[0020] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be made with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] See Figures 1 to 5 , a circuit board of a wireless remote control according to an embodiment of the present utility model, includes a first PCB board 1 and a second PCB board 2. The first PCB board 1 is provided with a key function circuit 11 of the wireless remote control, and the second PCB board 2 is provided with a wireless radio frequency circuit 21 of the wireless remote control; the second PCB board 2 is fixedly connected to the first PCB board 1 in a patch manner.

[0024] In this embodiment, optionally, the first PCB board 1 is a single-sided cardboard, and the second PCB board is a double-sided module PCB board. The key function circuit 11 and the wireless radio frequency circuit 21 are respectively independently arranged on two boards, effectively avoiding the problem that the key metal of the traditional wireless remote control interferes with the wireless radio frequency, and providing a low-impedance and short-distance return path for the signal effectively. The first PCB board can be changed in shape according to customer requirements, and the wireless radio frequency can uniformly adopt the second PCB board, without the need for additional PCB layout design and wireless radio frequency debugging for the wireless radio frequency circuit 21, reducing the design cost and manufacturing cost. The patch manner can be SMT (Surface Mounted Technology) patching to realize the docking of the first PCB board and the second PCB board.

[0025] In some embodiments, see Figure 4 , the wireless radio frequency circuit 21 includes a main control chip 211 and a wireless radio frequency antenna 212 connected to the main control chip 211 to realize the wireless communication function of the remote control.

[0026] Optionally, the main control chip 211 is provided with a pin pad 2111, and the first PCB board 1 is provided with a preset pad 12 corresponding to the pin pad 2111. The pin pad 2111 is solder-pasted to the preset pad 12 to realize the docking of the first PCB board 1 and the second PCB board 2, forming a complete circuit board of the wireless remote control, so as to realize the wireless communication function and button function of the wireless remote control.

[0027] Optionally, the preset pad 12 and the button function circuit 11 are on the same side of the first PCB board 1. Specifically, the preset pad 12 and the button function circuit 112 are on the same side of the first PCB board 1, so as to facilitate the layout of the metal button 111 on the first PCB board 1 for the user to press the button, and at the same time effectively avoid the interference of the button metal on the radio frequency, ensuring the working stability of the radio frequency circuit 21.

[0028] In some embodiments, the patch position of the second PCB board 2 corresponding to the first PCB board 1 is a blank area 13 to further avoid the interference of the button function circuit on the radio frequency and ensure the working stability of the radio frequency circuit 21.

[0029] In some embodiments, the radio frequency circuit 21 is arranged on one side of the second PCB board 2, and the other side of the second PCB board 2 is patched with the first PCB board 1, so that the radio frequency circuit 21 is far away from the metal button 111 and the button function circuit 112 of the first PCB board 1, further avoiding the interference of the button metal and the circuit on the radio frequency.

[0030] In some embodiments, see Figure 2 and Figure 3 , the button function circuit 11 includes a plurality of metal buttons 111 and button function circuits 112. Among them Figure 3 the shown metal button 111 is the side for the user to operate the button, Figure 2 the shown metal button 111 is the side connected to the button function circuit 112.

[0031] In some of these embodiments, the size of the second PCB board 2 is smaller than that of the first PCB board 1 to save the size space of the second PCB board 2, so as to be more easily adapted to various specifications of the first PCB board 1 and meet the requirements of different wireless remote control product shapes.

[0032] The present utility model also provides a wireless remote control, including the circuit board of the above-mentioned wireless remote control.

[0033] The wireless remote control of this embodiment separately arranges the key function part on the first PCB board to meet the customer's requirement of changing the appearance according to different remote controls, and separately arranges the wireless radio frequency part on the second PCB board. All remote controls can share the same type of wireless radio frequency module and unify the radio frequency parameters, without the need to redesign the appearance of the wireless radio frequency part and conduct additional wireless radio frequency debugging, thus reducing the design cost and manufacturing cost. At the same time, the key function part and the wireless radio frequency part are separately manufactured on boards, effectively avoiding the problem that the metal of the keys in traditional wireless remote controls interferes with the wireless radio frequency, and providing a low-impedance and short-distance return path for the effective signal.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0035] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
