Referring to fig. 1, 3 and 4, the present invention proposes a remote control device 300 for controlling a display device 400, wherein the display device 400 has a first receiving unit 410. The remote control device 300 includes a remote control device body 100 and an auxiliary transmission unit 200, the auxiliary transmission unit 200 being detachably connected to the remote control device body 100. The remote control device body 100 includes a first control unit 110, a first transmitting unit 120, a switch unit 130, a first connecting unit 140 and a power unit 150, where the first control unit 110 is connected to the power unit 150 and the first connecting unit 140, the switch unit 130 is connected between the first transmitting unit 120 and the first connecting unit 140, and the switch unit 130 is used for establishing or disconnecting electrical connection between the first transmitting unit 120 and the first connecting unit 140. In addition, the auxiliary transmitting unit 200 includes an extension line body 210, and a second transmitting unit 220 and a second connecting unit 230 disposed at both ends of the extension line body 210, wherein the second connecting unit 230 is matched with the first connecting unit 140.
When the second connection unit 230 is not connected to the first connection unit 140, that is, when the remote control device 300 is in the first state, the switch unit 130 establishes an electrical connection between the first transmission unit 120 and the first connection unit 140, and the remote control device 300 transmits a signal through the first transmission unit 120 to enable the first transmission unit 120 to be in butt joint with the first receiving unit 410. The first transmitting unit 120 of the remote control device body 100 in this state can be directly abutted with the first receiving unit 410.
When the second connection unit 230 is connected to the first connection unit 140, i.e. the remote control device 300 is in the second state, the switch unit 130 disconnects the electrical connection between the first transmission unit 120 and the first connection unit 140, the remote control device 300 transmits a signal through the second transmission unit 220, and the relative position of the second transmission unit 220 and the remote control device body 100 can be changed by the extension line body 210, so that the second transmission unit 220 is in butt joint with the first receiving unit 410. In this state, the first transmitting unit 120 of the original remote control device body 100 cannot meet the condition of interfacing with the first receiving unit 410, and at this time, the second transmitting unit 220 can change the relative position with respect to the remote control device body 100 under the guidance of the extension body 210 by utilizing the extendable and bendable characteristics of the extension body 210 by means of the access of the auxiliary transmitting unit 200, so that the second transmitting unit 220 interfaces with the first receiving unit 410.
The invention is based on the existing remote control device and adds an auxiliary transmitting unit comprising a second transmitting unit, when the remote control device is in a second state, the remote control device transmits signals through the second transmitting unit, and the characteristics of the auxiliary transmitting unit such as extensibility and flexibility can enable the remote control device to be applicable to various use scenes in which the transmitting unit cannot be directly aligned with the receiving unit, for example, the first receiving unit is arranged on the back of the display device; when in the first state, the remote control device transmits signals through the first transmitting unit, the auxiliary transmitting unit is not needed to be connected at the moment, and the remote control device body can be applied to normal use scenes like the existing remote control device.
As shown in fig. 1, in an embodiment of the invention, the first control unit 110 is connected to the switch unit 130, and the first control unit 110 can generate different control signals according to the connection state of the first connection unit 140. Specifically, when the second connection unit 230 is connected to the first connection unit 140 (i.e., the second state), the first control unit 110 outputs a second control signal, and the switch unit 130 disconnects the electrical connection between the first emission unit 120 and the first connection unit 140 according to the second control signal; when the second connection unit 230 is not connected to the first connection unit 140 (i.e., the first state), the first control unit 110 outputs a first control signal, and the switch unit 130 establishes an electrical connection between the first transmitting unit 120 and the first connection unit 140 according to the first control signal.
As shown in fig. 2, in another embodiment of the invention, the remote control device body 100 further includes a second control unit 170, the second control unit 170 is connected between the switch unit 130 and the first connection unit 140, and the second control unit 170 can generate different control signals according to the connection state of the first connection unit 140. Specifically, when the second connection unit 230 is connected to the first connection unit 140 (i.e., the second state), the second control unit 170 outputs a second control signal, and the switch unit 130 disconnects the electrical connection between the first emission unit 120 and the first connection unit 140 according to the second control signal; when the second connection unit 230 is not connected to the first connection unit 140 (i.e., the first state), the second control unit 170 outputs a first control signal, and the switch unit 130 establishes an electrical connection between the first transmitting unit 120 and the first connection unit 140 according to the first control signal.

Preferably, the first connection unit 140 is a jack similar to an earphone interface of 3.5mm or 2.5mm, and the second connection unit 230 is a plug similar to an earphone plug of 3.5mm or 2.5mm, that is, the signal plug of the auxiliary transmitting unit 200 only needs to correspond to the signal jack of the remote control device body 100. Because the earphone interface/earphone plug with the thickness of 3.5mm or 2.5mm is a common accessory, the remote control device is only needed to be modified by using the existing accessory, and the operation is easy.
In this embodiment, the first transmitting unit 120 and the second transmitting unit 220 are infrared transmitters, which are specifically infrared transmitting transistors. Of course, the first transmitting unit 120 and the second transmitting unit 220 may be other types of transmitters, which is not limited in the present invention.

The extension cord 210 may be bent/coiled for storage and stowing when not in use. It should be noted that, the extension line body 210 has a certain hardness, and has a certain shaping capability on the premise of ensuring free bending. In practical applications, when the second connection unit 230 is in the second state, the user only needs to access the first connection unit 140, and then extend the extension line 210 to the required position for shaping, and when the second connection unit 230 is in the first state, the user only needs to remove the second connection unit 140, and then bend/wind the second connection unit and store the second connection unit. It should be understood that the specific length, hardness, etc. of the extension cord 210 may be determined according to practical applications, and the invention is not limited thereto.
