[0012] As illustrated in FIGS. 1 to 3, in one embodiment, the mobile terminal 10 is a smart phone. The mobile terminal 10 includes a hand-held portion 100 and a host portion 200 which can be used separately. The hand-held portion 100 includes a first communication module, a first power supply module 110, and a display screen 120. The first power supply module 110 can be electrically connected to the first communication module and the display screen 120 respectively, and the first power supply module 110 is configured to supply power for the first communication module and the display screen 120. The display screen 120 can be used to display information, and the display screen 120 can also be used to provide an interactive interface for the user to interact with the hand-held portion 100, for example, to realize touch operation. The host portion 200 includes a camera module 210, a second communication module, a third communication module, and a second power supply module. The second power supply module can be electrically connected to the camera module 210, the second communication module, and the third communication module respectively, and the second power supply module is configured to supply power for the camera module 210, the second communication module, and the third communication module. The third communication module is used for communication with external equipments such as base stations or other terminals. In one embodiment, the host portion 200 includes a front surface 221, a back surface 223 opposite to the front surface 221, and a side surface 225 located between and connecting to the front surface 221 and the back surface 223, the front surface 221 is provided with a first installation slot 230, and the back surface 223 is provided with a second installation slot 240. A portion of the front surface 221 is used as a light incident surface 211 for the camera module 210 and allows light from environment to pass through and enter the camera module 210. The light can pass through the light incident surface 211 and be incident on the sensing element of the camera module 210. The hand-held portion 100 can be not only installed in the first installation slot 230, but also installed in the second installation slot 240. When the hand-held portion 100 is installed in the first installation slot 230 or the second installation slot 240, the hand-held portion 100 and the host portion 200 are combined to form the mobile terminal 10, and the mobile terminal 10 can be operated normally. The hand-held portion 100 can also be detached from the host portion 200. When the hand-held portion 100 is detached from the host portion 200, the second communication module can still communicate with the first communication module to realize the data transmission between the hand-held portion 100 and the host portion 200, and the hand-held portion 100 can still play the functions such as display, touch operation, so that the mobile terminal 10 can be operated normally by the user.

[0013] The first power supply module 110 may include a nuclear battery, such as a tritium battery, which is small in size, relatively light and thin, and has a long service life. The nuclear battery can provide power for the display screen 120, the first communication module, and other electronic components of the hand-held portion 100 for a long time, thereby facilitating the lightweight of the hand-held portion 100. In one embodiment, the first power supply module 110 may also include a lithium battery or the like, and the first power supply module 110 may repeatedly charge and discharge for many times to provide power for the display screen 120 and other electronic components of the hand-held portion 100. The function provided by the hand-held portion 100 can be relatively simple, so that the number of electronic components of the hand-held portion 100 is less, which is conducive to extending the endurance of the hand-held portion 100. In one embodiment, the second power supply module can include a lithium battery which can be repeatedly charged and discharged, and the second power supply module can provide power for the camera module 210, the second communication module, and the third communication module.

[0014] Both the first communication module and the second communication module adopt the short distance communication technology, and the first communication module and the second communication module adopt the same communication protocol. For example, the first communication module and the second communication module can both be Bluetooth communication module, or both are Wireless Fidelity (WiFi) communication module, or both are infrared data association (lrDA) module, or both are ZigBee communication module, or both are ultra wideband communication module, or both are near field communication (NFC) module. The communication connection between the first communication module and the second communication module can realize the data transmission between the hand-held portion 100 and the host portion 200. The data transmitted from the host portion 200 to the hand-held portion 100 can be further converted into signal for display, touch control and other signals, and the data transmitted from the hand-held portion 100 to the host portion 200 can be stored or processed. In other embodiments, the hand-held portion 100 may also include an audio output module for outputting sound, or an image capturing device for video recording and picture shooting, etc., which will not be discussed in detail here. The host portion 200 can also be provided with an audio output module and the like.

[0015] For the mobile terminal 10 above, the hand-held portion 100 includes a display screen 120, a first communication module, and a first power supply module 110. The first communication module can communicate with the second communication module of the host portion 200. The hand-held portion 100 can be separated from the host portion 200. After the hand-held portion 100 is separated from the host portion 200, and the hand-held portion 100 can receive the signal from the host portion 200 and provide display or other functions for the normal operation of the user, and the host portion 200 can be placed in a pocket or other location. The structure of the hand-held portion 100 is relatively simple, so the hand-held portion 100 can be made extremely light and thin, and the electronic components of the hand-held portion 100 can be less, so the endurance of the hand-held portion 100 can be improved. A larger battery can be located in the host portion 200 to improve the endurance of the host portion 200 and avoid affecting the portability of the hand-held portion 100. Understandably, the mobile terminal 10 can also be a tablet computer or a palmtop computer, etc.

[0016] In the embodiment shown in FIG. 3, the first installation slot 230 or the second installation slot 240 is a circumferential structure with an opening, namely, the first installation slot 230 can extends to entire the side surface 225 of the host portion 200, and the second installation slot 240 can also extends to entire the side surface 225 of the host portion 200. For example, the cross section of the first installation slot 230 may be approximately U-shaped, and the cross section of the second installation slot 240 may be approximately U-shaped. The hand-held portion 100 can be installed into the first installation slot 230 from the side of the side surface 225, so that the orientation of the display screen 120 is the same as that of the light incident surface 211. At this time, the camera module 210 can perform the function of the front camera, so as to facilitate self shooting, video calling, and other operations for the user. The hand-held portion 100 can also be installed into the second installation slot 240 from the side of the side surface 225, so that the orientation of the camera module 210 is the same or opposite to that of the display screen 120. Taking the open structure of the first installation slot 230 as an example, the above structure enables the user to insert the hand-held portion 100 into the first installation slot 230 of the host portion 200 from the side of the side surface 225 of the host portion 200, and the groove wall of the first installation slot 230 can be used for guiding, so as to facilitate the insertion and removal of the hand-held portion 100.

[0017] As illustrated in FIGS. 4 and 5, in one embodiment, the first installation slot 230 and the second installation slot 240 are in a circumferential closed structure. In the embodiment shown in FIG. 4, the hand-held portion 100 can be installed into the first installation slot 230 from the side of the front surface 221 of the host portion 200, so that the orientation of the display screen 120 is the same as that of the light incident surface 211. At this time, the camera module 210 can perform the function of the front camera, so as to facilitate self shooting, video calling, and other operations for the user. It is understandable that the orientation of the display screen 120 refers to the orientation of the side of the display surface of the display screen 120. The display surface of the display screen 120 is a surface that the user can directly contact, the display surface can display information, and can provide an interactive interface for the user to touch, operate, etc. As illustrated in FIG. 5, the hand-held portion 100 can also be installed into the second installation slot 240 from the side of the back surface 223 of the host portion 200, so that the orientation of the display screen 120 is opposite to the orientation of the light incident surface 211. At this time, the camera module 210 may perform the function of a back camera to facilitate the user to perform operations such as picture shooting or video recording. The above mobile terminal 10 can avoid setting the camera module on both the front surface 221 and the back surface 223 of the host portion 200, thus reducing the number of components and saving the cost of the mobile terminal 10. Furthermore, the camera module 210 can have higher resolution, thus improving the quality of self shooting and back shooting.

[0018] In the embodiment shown in FIG. 3, the first installation slot 230 and the second installation slot 240 are intercommunicated with each other so that the host portion 200 is hollow. In one embodiment, the hand-held portion 100 can be installed into the first installation slot 230 from the side of the side surface 225, so that the orientation of the display screen 120 is opposite to the orientation of the light incident surface 211. Since the host portion 200 is hollow, the user can also view the information from the side of the back surface 223. At this time, the camera module 210 may perform the function of a back camera to facilitate the user to perform operations such as picture shooting or video recording. The hand-held portion 100 can also be installed into the second installation slot 240 from the side of the side surface 225, so that the orientation of the camera module 210 is the same or opposite to that of the display screen 120. As illustrated in FIGS. 6 to 8, in another embodiment, the first installation slot 230 and the second installation slot 240 are arranged on the opposite sides and are not intercommunicated with each other, that is, the first installation slot 230 and the second installation slot 240 are isolated. When the hand-held portion 100 is installed into the first installation slot 230 from the side of the side surface 225 so that the orientation of the display screen 120 is opposite to the orientation of the light incident surface 211, the host portion 200 shelter the display surface of the display screen 120, which can prevent the display surface from being exposed, thus preventing the display surface of the display screen 120 from being damaged by accidental collision. It can be understood that when the hand-held portion 100 can be installed into the second installation slot 240 from the side of the side surface 225 so that the orientation of the display screen 120 is the same as that of the light incident surface 211, the host portion 200 can also shelter the display surface of the display screen 120, prevent the display surface from being exposed, and thus prevent the display surface of the display screen 120 from being damaged by accidental collision.

[0019] As illustrated in FIG. 9 and FIG. 10, in one embodiment, the hand-held portion 100 is substantially a rectangular plate. As further illustrated in FIGS. 11 and 12, the first installation slot 230 may be used as the second installation slot 240. The hand-held portion 100 includes a front end surface 131, a back end surface 133 and a side end surface 135 connecting the front end surface 131 and the back end surface 133. The display screen 120 is arranged on the front end surface 131. The hand-held portion 100 can be installed into the first installation slot 230 from the side of the front end surface 131 and can also be installed into the first installation slot 230 from the side of the back end surface 133. Specifically, two sides of the hand-held portion 100 can be set as a symmetrical structure, and two sides of the first installation slot 230 can be set as a symmetrical structure correspondingly. In the operation process, the user can install the hand-held portion 100 into the host portion 200 with the front face 131 facing the host portion 200, or install the hand-held portion 100 into the host portion 200 with the back end surface 133 facing the host portion 200. On one hand, the orientation of the display screen 120 and the orientation of the light incident surface 211 can be arranged to be the same or opposite. On the other hand, it is unnecessary for the user to deliberately locate the front end surface 131 or the back end surface 133 of the hand-held portion 100, and the user can install the hand-held portion 100 into the host portion 200 with any one of the front end surface 131 and the back end surface 133 facing the host portion 200, thus facilitating the assembly of the hand-held portion 100 and the host portion 200, and improving the convenience for user to assemble.

[0020] It can be understood that the mobile terminal 10 can include two hand-held portions 100, one is arranged on the first installation slot 230 and the other one is arranged on the second installation slot 240, so that the host portion 200 has the function of double-sides display. The two hand-held portions 100 can be separated from the host portion 200 and can be operated independently, so that the two hand-held portions 100 can be operated by the same user or different users. It can be understood that the number of hand-held portions 100 can be more than three, corresponding the number of the first installation slot 230 and the second installation slot 240 can be more than three, and multiple hand-held portions 100 can be operated by the same user or different users. For example, a family can have a single host portion 200, but has multiple hand-held portions 100, so as to save the cost and improve the convenience for the family.

[0021] As illustrated in FIG. 11 and FIG. 12, two opposite side walls of the first installation slot 230 can be provided with a groove 231 which extends along the length direction (x-axis direction) of the host portion 200. The side surface of the hand-held portion 100 is provided with a guide rail 140 matchable to the groove 231, and the guide rail 140 can be accommodated in the groove 231. It can be understood that the outer circumference of the display screen 120 of the hand-held portion 100 can be provided with a metal or plastic support structure, and the guide rail 140 can be installed on the support structure, so that the guide rail 140 becomes a part of the hand-held portion 100. In the embodiment shown in FIG. 11, in a plane perpendicular to the length direction of the host portion 200, the cross section of the groove 231 is approximately trapezoid, and the cross section of the guide rail 140 is approximately trapezoid. The guide rail 140 and the groove 231 allow the host portion 200 to hold the two sides of the hand-held portion 100, so as to prevent the hand-held portion 100 from easily separating from the host portion 200.

[0022] In one embodiment, when the hand-held portion 100 is inserted into the first installation slot 230 and the orientation of the display screen 120 is the same as that of the light incident surface 211, the surface of the display screen 120 away from the back end surface 133 can be flush with the front surface 221 of the host portion 200, so as to improve the integration of the mobile terminal 10 and beautify the appearance of the mobile terminal 10. In one embodiment, when the hand-held portion 100 is inserted into the second installation slot 240 and the orientation of the display screen 120 is opposite to the orientation of the light incident surface 211, the surface of the display screen 120 away from the back end surface 133 can be flush with the back surface 223 of the host portion 200, so as to further improve the integration of the mobile terminal 10 and beautify the appearance of the mobile terminal 10.
