Description

FIELD OF THE INVENTION

[0001] The present invention relates to a wireless remote control receiver, and more particularly to a technology of transmitting a radio frequency control signal from a remote controller module to a receiver module, and converting the radio frequency control signal into an infrared control signal, and transmitting the infrared control signal to an electronic device.

BACKGROUND OF THE INVENTION

[0002] In the past, an electronic device such as a home appliance, an audio/video device or a consumer electronic product generally used many switches or buttons installed on the electronic device for its control, but such control is inconvenient, since users have to be near the electronic device to operate the electronic device.

[0003] At present, a wireless remote control receiver applicable for remote controlling an electronic device is well known in the art, and such conventional wireless remote control receiver comprises a remote controller module and a receiver module, wherein the remote controller module includes at least one keyboard (which is a press key set), a processing unit and an infrared transmitter circuit, so that users can input a signal by using the keyboard, and the processing unit drives an infrared transmitter circuit to transmit an infrared control signal based on the input signal, and the receiver module is electrically coupled to an electronic device and has at least one infrared receiving sensor for receiving the infrared control signal, and transmitting the infrared control signal to the electronic device through a cable, so as to achieve the purpose of remote controlling the electronic device.

[0004] Referring to FIG. 1 for a schematic view of the aforementioned wireless remote control receiver, the wireless remote control receiver comprises a remote controller module 11 and a receiver module 12, wherein the remote controller module 11 includes at least one first power supply circuit 111, a keyboard 112, a processing unit 113 and an infrared transmitter circuit 114. The first power supply circuit 111 provides a first supply power to the keyboard 112, the processing unit 113 and the infrared transmitter circuit 114, and users input a signal (not shown in the figure) by using the keyboard 112, and the processing unit 113 drives the infrared transmitter circuit 114 to transmit an infrared control signal (wireless) 115 to outside based on the input signal. The receiver module 12 is electrically coupled to an electronic device 13 and has at least one second power supply circuit 121 and an infrared receiving sensor 122. The second power supply circuit 121 provides a second supply power to the infrared receiving sensor 122. The infrared receiving sensor 122 is used to receive an infrared control signal (wireless) 115 and transmit the infrared control signal (cable) 123 to a processor 131 of the electronic device 13 through a cable, so as to achieve the purpose of remote controlling the electronic device 13.

[0005] The shortcoming of the foregoing conventional wireless remote control receiver resides in that the penetrating power of the infrared control signal transmitted by the remote controller module is poor, and thus the signal transmission may be blocked by obstacles easily and even not operable at all. Furthermore, the signal receiving angle and position of the receiver module are very limited, so that the remote controller module must be aligned precisely with the receiver module for good receptions, and the transmission distance of the infrared control signal is short, so that the transmission effect will be affected adversely if the receiver module is too far away from the remote controller module.

[0006] To overcome the shortcomings of the conventional wireless remote control receivers and satisfy the user requirements of the wireless remote control receiver, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally developed a wireless remote control receiver in accordance with the present invention.

SUMMARY OF THE INVENTION

[0007] It is a primary objective of the present invention to provide a wireless remote control receiver, and more particularly to the technology that a remote controller module transmits a radio frequency control signal to a receiver module and the receiver module converts the radio frequency control signal into an infrared control signal, and transmits the infrared control signal to an electronic device, so as to satisfy the user requirements of the wireless remote control receiver and overcome the shortcomings of the conventional wireless remote control receivers. The present invention not only provides a powerful penetration that cannot be blocked by obstacles easily, but also has less limitation on the signal receiving angle and position. In addition, the present invention features the advantages of a long transmission distance and an excellent transmission effect.

[0008] To achieve the foregoing objective, the present invention provides a wireless remote control receiver comprising a remote controller module and a receiver module, wherein the remote controller module includes at least one input unit, a first processing unit and a radio frequency transmitter, and the input unit inputs a signal to the first processing unit, and the first processing unit drives the radio frequency transmitter to transmit a radio frequency control signal based on the input signal, and the receiver module is electrically coupled to an electronic device and includes at least one radio frequency receiver and a second processing unit, and the radio frequency receiver receives a radio frequency control signal, and a second processing unit converts the radio frequency control signal into an infrared control signal and transmits the infrared control signal to the electronic device.
