  5. (5) a conventional laptop and/or palmtop radio phone transceiver and the like.


[0010] Referring to Fig. 1 and Fig. 2, in an embodiment, a mobile terminal 10 is a smart phone, and may also be a tablet computer. The mobile terminal 10 includes a terminal device 100 and an image acquisition module 200.

[0011] The terminal device 100 includes a first surface 101, a second surface 102 opposite the first surface 101, and a lateral peripheral surface 103 coupled between the first surface 101 and the second surface 102. The terminal device 100 is provided with a mounting groove, and the mounting groove passes through the lateral peripheral surface 103. In some exemplary embodiments, the terminal device 100 is substantially of a rectangular block shaped, the lateral peripheral surface 103 includes a top lateral surface 103a, a bottom lateral surface 103b, a left lateral surface 103c and a right lateral surface 103d, the top lateral surface 103a is opposite to the bottom lateral surface 103b, and the left lateral surface 103c is opposite to the right lateral surface 103d. The top lateral surface 103a and the bottom lateral surface 103b are positioned between the left lateral surface 103c and the right lateral surface 103d, and the left lateral surface 103c and the right lateral surface 103d are positioned between the top lateral surface 103a and the bottom lateral surface 103b.

[0012] The image acquisition module 200 is arranged at the mounting groove, and is able to move relative to the terminal device 100 to a first position and a second position. In combination with Fig. 3 and Fig. 4, the image acquisition module 200 includes a mounting seat 210, a camera assembly 220 and a light source 230, and the camera assembly 220 has an incident surface 220a. In some exemplary embodiments, the mounting groove is able to pass through any one or more lateral surfaces of the lateral peripheral surface 103. For example, in the mobile terminal 10 shown in Fig. 1 and Fig. 2, the mounting groove only passes through the top lateral surface 103a, and correspondingly, the image acquisition module 200 is able to extend from or retract into the mounting groove from the top lateral surface 103a. In other exemplary embodiments, the mounting groove is also able to pass through the left lateral surface 103d or the bottom lateral surface 103b only, or the mounting groove passes through both the top lateral surface 103a and the right lateral surface 103d. There are no limits made herein.

[0013] At the first position, the mounting groove accommodates the image acquisition module 200 and the incident surface 220a is kept hidden in the terminal device 100, so that an arrangement space on a side where the first surface 101 or the second surface 102 is positioned may be prevented from being occupied, the first surface 101 and the second surface 102 are relatively complete, and furthermore, when a display screen 110 is arranged on the first surface 101 or the second surface 102, a display region 110a of the display screen 110 is able to make larger to increase a screen-to-body ratio. For example, in some exemplary embodiments, the display screen 110 of the terminal device 100 is arranged on the side where the first surface 101 is positioned or the side where the second surface 102 is positioned. To be precise, the display region 110a of the display screen 110 faces the side where the first surface 101 is positioned or the side where the second surface 102 is positioned. The display screen 110 is configured to display information and provide an interaction interface for a user to meet a using requirement on the terminal device 100. In some exemplary embodiments, display screens 110 are arranged on both the side where the first surface 101 is positioned and the side where the second surface 102 is positioned to achieve a double-screen display effect. In other exemplary embodiments, the display screen 110 is able to get a flexible screen, and has a first display region and a second display region, the first display region faces the side where the first surface 101 is positioned, and the second display region faces the side where the second surface 102 is positioned, so that a double-sided display effect may also be achieved. Elaborations are omitted herein.

[0014] At the second position, the image acquisition module 200 extends from the mounting groove, and the incident surface 220a exposes from the side where the first surface 101 is positioned. Therefore, shooting towards the side where the first surface 101 is positioned is able to implement. It is to be noted that, when the display region 110a of the display screen 110 faces the side where the first surface 101 is positioned, a glass cover plate covering the display screen 110 forms part or all of the first surface 101. In such case, the incident surface 220a exposes from the side where the first surface 101 is positioned, and this means that the camera assembly 220 is able to shoot towards a side where the display region 110a of the display screen 110 is positioned. Correspondingly, in some other exemplary embodiments, the display region 110a of the display screen 110 faces the side where the second surface 102 is positioned, so that, when the incident surface 220a exposes from the side where the first surface 101 is positioned, a shooting direction of the camera assembly 220 is opposite the second surface 102, namely shooting opposite the side where the display region 110a of the display screen 110 is implemented.

[0015] In combination with Fig. 3 and Fig. 4, the mounting seat 210 includes a pedestal 211 and a light transmission member 212, the light transmission member 212 is coupled to the pedestal 211, and the light transmission member 212 and the pedestal 211 cooperatively define a receiving cavity. The camera assembly 220 is arranged in the receiving cavity, and the incident surface 220a exposes from the light transmission member 212. The light source 230 is configured to emit light transmitting through the light transmission member 212. By such arrangement, the light of the light source 230 is transmitted from the side where the incident surface 220a is positioned by use of the light transmission member 212, thereby achieving a relatively good light effect outside the camera assembly 220, improving the whole aesthetics of the camera assembly 220 and improving a shooting experience.

[0016] The light transmission member 212 may be made from a light transmission glass material such as optical quartz glass and ultraviolet transmission glass, and may also be made from a plastic material with relatively high light transmittance such as polymethyl methacrylate (PMMA), polystyrene (PS) and polycarbonate (PC). In addition, the light transmission member 212 and the pedestal 211 is able to connect into a whole in a buckle connecting manner without any connecting piece such as a screw and a jackscrew, so that the number of parts is reduced, and assembling is facilitated. In other exemplary embodiments, the light transmission member 212 may also be adhered to the pedestal 211 by glue, which may also firmly connect the light transmission member 212 to the pedestal 211 to form the receiving cavity.

[0017] The image acquisition module 200 includes a first flexible printed circuit 240 and a second flexible printed circuit 250, and a main board is arranged in the terminal device 100. The light source 230 is electrically connected to the main board by the first flexible printed circuit 240 such that the main board may control the light source 230. For example, when the image acquisition modules 200 moves out of the mounting groove, the main board controls the light source 230 to emit a beam to achieve a light effect on the side where the incident surface 220a of the camera assembly 220 is positioned. It is to be noted that the light source 230 is a Light-Emitting Diode (LED) lamp, may emit monochromatic light, and may also emit red, green or yellow light, to achieve different light effects. There are no limits made herein. The camera assembly 220 is electrically connected with the main board by the second flexible printed circuit 250 such that the main board may control a shooting state of the camera assembly 220 for adaptation to a shooting requirement. In some exemplary embodiments, after the light transmission member 212 is coupled to the pedestal 211, a wire passage opening is reserved therebetween such that the second flexible printed circuit 250 passes through the wire passage opening to be electrically connected to the camera assembly 220 in the receiving cavity. In other exemplary embodiments, a connecting port electrically connected to the camera assembly 220 is formed in the pedestal 211, so that the second flexible printed circuit 250 is electrically connected to the camera assembly 220 when the second flexible printed circuit 250 is coupled to the connecting port, and furthermore, when the second flexible printed circuit 250 is electrically connected to the main board, a current or a signal is transmitted between the main board and the camera assembly 220 to implement shooting control of the main board over the camera assembly 220.

[0018] The first flexible printed circuit 240 and the second flexible printed circuit 250 is electrically connected to the main board through a board-to-board connector. For example, for the first flexible printed circuit 240, a connector plug is arranged on the first flexible printed circuit 240, a connector jack is formed in the main board, and the connector plug mates with the connector jack to implement electrical connection between the connector plug and the connector jack. In other exemplary embodiments, the first flexible printed circuit 240 and the second flexible printed circuit 250 may also be coupled to the main board in a welding manner. There are no limits made herein.

[0019] Still referring to Fig. 3, the first flexible printed circuit 240 has a first retractable section 241, and the second flexible printed circuit 250 has a second retractable section 251. When the image acquisition module 200 moves relative to the terminal device 100, the first retractable section 241 and the second retractable section 251 extend or retract. In such an arrangement manner, when the image acquisition module 200 moves relative to the terminal device 100, the first flexible printed circuit 240 and the second flexible printed circuit 250 may adaptively extend or retract, which ensures that the first flexible printed circuit 240 and the second flexible printed circuit 250 may move independently relative to each other, so that interference caused by intertwining of the first flexible printed circuit 240 and the second flexible printed circuit 250 to the image acquisition module 200 is avoided, a movement effect of the image acquisition module 200 is effectively ensured, and the first flexible printed circuit 240 and the second flexible printed circuit 250 are prevented from being damaged during movement of the image acquisition module 200.

[0020] In some exemplary embodiments, when the image acquisition module 200 moves to the first position, the first retractable section 241 bends to wrap a part of a structure of the light transmission member 212. That is, at the first position, a part of a structure of the light transmission member 212 is accommodated in a space formed by bending of the first retractable section 241, so that an internal mechanism of the terminal device 100 is more compact, which is adoptable for lightening and thinning of the terminal device 100.

[0021] In some exemplary embodiments, at the first position, the second retractable section 251 bends to wrap the first retractable section 251, so that a layout of the first flexible printed circuit 240 and the second flexible printed circuit 250 is more compact, an internal space of the terminal device 100 may be used completely, and lightening and thinning design of the terminal device 100 is facilitated. In addition, in such an arrangement manner, the flexible printed circuit 240 and the second flexible printed circuit 250 may be stacked together, so that the first retractable section 241 and the second retractable section 251, when the image acquisition module 200 moves relative to the terminal device 100, may synchronously extend or retract without interference therebetween.

[0022] In some exemplary embodiments, the first flexible printed circuit 240 has a first connecting section 242 coupled to the first retractable section 241, the second flexible printed circuit 250 has a second connecting section 252 coupled to the second retractable section 251, the first connecting section 242 is coupled to the second connecting section 252, and the first connecting section 242 and the second connecting section 252 are electrically connected to the main board respectively. The first connecting section 242 and the second connecting section 252 are coupled to connect the first flexible printed circuit 240 and the second flexible printed circuit 250 into a whole, so that centralized arrangement of the first flexible printed circuit 240 and the second flexible printed circuit 250 is facilitated, assembling of the light source 230, the camera assembly 220 and the main board is simplified, and the image acquisition module 200 is able to get rapidly assembled to the terminal device 100. In addition, when a part of assembly such as the light source 230 is damaged, the light source 230 can be replaced only by disconnecting the first flexible printed circuit 240 from the light source 230, so that convenience for operation is ensured.

[0023] In combination with Fig. 3, in one embodiment, the light transmission member 212 includes a first mounting portion 2121, the first mounting portion 2121 is provided with a receiving groove 21211, and a part of the structure of the pedestal 211 is arranged at a groove opening of the receiving groove in a covering manner to define the receiving cavity. An enough receiving space is provided for the camera assembly 220 by use of the receiving groove 21211 of the first mounting portion 2121. In addition, since the camera assembly 220 is received in the receiving cavity, when the light emitted by the light source 230 is transmitted to the outside by the light transmission member 212, a relatively good light effect is achieved around the camera assembly 220.

[0024] In some exemplary embodiments, the groove opening of the receiving groove 21211 is opposite to a side where the incident surface 220 is positioned, and then the camera assembly 220, when being arranged, can be placed into the receiving groove 21211 from a direction of the side where the incident surface 220a is positioned, so that most of the structure of the camera assembly 220 is wrapped with the light transmission member 212, and furthermore, when the light emitted by the light source 230 is transmitted by the light transmission member 212, a better glare effect is achieved around the camera assembly 220.

[0025] In one embodiment, the first mounting portion 2121 includes a top end face 2121a, a front end face 2121b and a bottom end face 2121c which are sequentially abutted, and the incident surface 220a exposes from the front end face 2121b to meet the shooting requirement of the camera assembly 220. It is to be noted that, since the incident surface 220a exposes from the side where the first surface 101 is positioned after the image acquisition module 200 moves relative to the terminal device 100 to the second position, shooting towards the side where the first surface 101 is positioned may be implemented. In such case, the light transmission member 212 may transmit the beam emitted by the light source 230 to the outside for emission from the side where the front end face 2121b is positioned, and a relatively good light effect may further be achieved around the camera assembly 220.

[0026] In some exemplary embodiments, the light transmission member 212 includes a second mounting portion 2122, the second mounting portion 2122 is coupled to the bottom end face 2121c, the light source 230 is arranged at the second mounting portion 2122, the light emitted by the light source 230 is incident towards the side where the bottom end face 2121c is positioned till the second mounting portion 2122, thereby lighting the first mounting portion 2121, and the light is transmitted by the first mounting portion 2121 and emitted from the side where the incident surface 220a is positioned to achieve a relatively good light effect.

[0027] In some exemplary embodiments, the light transmission member 212 is provided with a sunken region, and at the second position, the sunken region accommodates the first connecting section 242 and a part of the second connecting section 252. In such an arrangement manner, when the image acquisition module 200 is at the second position, the first flexible printed circuit 240, the second flexible printed circuit 250 and the light transmission member 212 are more compact, so that an internal arrangement space of the terminal device 100 is effectively saved for lightening and thinning design of the terminal device 100.

[0028] The sunken region can be formed by step connection of the second mounting portion 2122 to the bottom end face 2121c. To be precise, the bottom end face 2121c and a surface of the second mounting portion 2122 define the sunken region.

[0029] As shown in Fig. 3, the second mounting portion 2122 is provided with an accommodation groove 2122a, and the light source 230 is arranged in the accommodation groove 2122a. A sunken region 2122b communicated with the accommodation groove 2122a is defined in the second mounting portion 2122, and the first flexible printed circuit 240 is partially accommodated in the sunken region 2122b and electrically connected to the light source 230. Under such structural arrangement, it is ensured that the light emitted by the light source 230 can be incident to the light transmission member 212 well; and in addition, the structures of the light source 230 and the second mounting portion 2122 are more compact, and the size of the whole image acquisition module 200 is reduced, so that a space required by arrangement of the image acquisition module 200 in the terminal device 100 is as small as possible, which is adoptable for lightening and thinning design of the terminal device 100.

[0030] Furthermore, in the embodiment that the first flexible printed circuit 240 has the first retractable section 241, the first retractable section 241 is able to bend to wrap the second mounting portion 2122, thereby making the structure more compact. In such an arrangement manner, when the first retractable section 241 extends or retracts along with movement of the image acquisition module 200 relative to the terminal device 100, the first flexible printed circuit 240 may extend and retract stably without interference with the second mounting portion 2122 to avoid influence on the effect of movement of the image acquisition module 200 relative to the terminal device 100.

[0031] In one embodiment, the receiving groove 21211 passes through the top end face 2121a, the pedestal 211 includes an end cover 2111, and the end cover 2111 is arranged on the top end face 2121a in the covering manner, thereby covering the receiving groove 21211 from a side where the top end face 2121a is positioned and making the whole appearance of the mounting seat 210 more attractive. In addition, the end cover 2111 may also achieve a shading effect to prevent the light transmitted by the light transmission member 212 from being emitted from the side where the top end face 2121a is positioned and ensure that the light can be emitted from the side where the front end face 2121b is positioned as much as possible to effectively achieve a light effect on the side where the incident surface 220a is positioned.

[0032] In combination with Fig. 5, in one embodiment, the camera assembly 220 includes an inductive sensor 221 and a lens group 222, and the inductive sensor 221 is electrically connected to the second flexible printed circuit 250, so that, when the image acquisition module 200 is assembled to the terminal device 100, the second flexible printed circuit 250 can be coupled the main board in the terminal device 100 to electrically connect the inductive sensor 221 with the main board to further transmit data or currents. In the exemplary embodiment, external light can be incident to the inductive sensor 221 through the lens group 222. The first mounting portion 2121 is provided with a bayonet communicated with the receiving groove 21221, and the lens group 222 is arranged at the bayonet. By the bayonet, the camera assembly 2210 is able to get positioned on one hand, and on the other hand, a clearance space may also be provided for the lens group 222, the lens group 222 being positioned at the bayonet, so that, when the light emitted by the light source 230 is incident to the light transmission member 212, the light transmission member 212 may lead the light out to form a light ring around the lens group 222 to achieve a relatively good glowing effect.

[0033] Referring to Fig. 6, Fig. 6 is a structure of a terminal device 100 according to an embodiment of the present disclosure. The terminal device 100 includes assemblies such as a Radio Frequency (RF) circuit 601, and one or more than one computer-readable storage medium including a memory 602, an input unit 603, a display unit 604, a sensor 604, an audio circuit 606, a Wireless Fidelity (WiFi, Wireless Fidelity) module 607, a processor 608 including a plurality of processing cores, and a power supply 609.

[0035] The memory 602 is configured to store an application program and data. The application program stored in the memory 602 includes an executable code. The application program is able to form various functional modules. The processor 608 runs the application program stored in the memory 602, thereby executing various functional present disclosures and data processing. The memory 602 mainly includes a program storage region and a data storage region. The program storage region stores an operating system, an application program required by at least one function (for example, a sound playing function and an image playing function) and the like. The data storage region may store data (for example, audio data and a phone book) created according to use of the terminal device 100 and the like. In addition, the memory 602 includes a high-speed random access memory and further includes a nonvolatile memory, for example, at least one disk storage device, flash memory device or other volatile solid-state storage device. Correspondingly, the memory 602 further includes a memory controller for providing access to the memory 602 for the processor 608 and the input unit 603.
