Description

Technical Field

[0001] This utility model relates to a PCB built-in antenna assembly and a shooting device. Background Technology

[0002] Currently, when camera products or electronic products have built-in PCB antennas, they are directly glued or taped to the product housing. However, after long-term use, the PCB antenna is prone to displacement, and when there are interference sources around the PCB antenna, the antenna placement is not unique. When fixing the PCB antenna in a narrow space, the placement may also be offset by different employees, or the antenna may not be firmly attached, which has a significant impact on the antenna's efficiency and performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a PCB-embedded antenna assembly and imaging device that can ensure the unique and fixed position of the antenna.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, a PCB built-in antenna assembly is provided, including a PCB antenna body, one side of which is attached with foam, and the other side is attached with a flexible fastener for compression assembly into an external device housing, and the inner side of the flexible fastener is attached to the antenna on the PCB antenna body.

[0005] A further technical solution is as follows: the inner side of the flexible fixing member is provided with a groove for placing the antenna at the position of the antenna.

[0006] The further technical solution is that the flexible fastener is made of silicone.

[0007] A further technical solution is that an adhesive layer is provided on the side of the foam that is away from the PCB antenna body.

[0008] A further technical solution is as follows: an avoidance groove is provided on the foam at the antenna position corresponding to the PCB antenna body.

[0009] The further technical solution is as follows: the PCB antenna body includes a PCB board and an antenna mounted on the PCB board. The antenna includes a wire and a terminal connected to the wire. The foam and the flexible fastener are respectively attached to both sides of the PCB board. The wire is located between the PCB board and the flexible fastener and is attached to the flexible fastener. The terminal passes through the clearance groove and is connected to the external circuit.

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, a shooting device is provided, including a lens module, a controller, a support arm for supporting the lens module, and the aforementioned PCB-embedded antenna assembly. The controller is connected to the lens module through an antenna in the PCB-embedded antenna assembly. The support arm has an accommodating space, and the PCB-embedded antenna assembly is located within the accommodating space. The foam is attached to one inner wall of the support arm, and the flexible fastener is pressed and fitted against another opposite inner wall of the support arm, so that the PCB-embedded antenna assembly is assembled within the accommodating space of the support arm in an interference fit manner.

[0011] The beneficial technical effects of this utility model are as follows: Compared with the prior art, in this utility model, the PCB antenna body of the PCB built-in antenna assembly has foam pasted on one side and a flexible fastener for compression assembly into the external device housing on the other side. The inner side of the flexible fastener is attached to the antenna on the PCB antenna body. It can be seen that when the PCB built-in antenna assembly of this utility model is used for assembly, the antenna position can be fixed by interference fit between the foam and the flexible fastener and the external device housing. Therefore, the antenna position will not be different due to different operators' assembly operations during the assembly process, which can ensure the unique fixation of the antenna position, ensure product consistency, and prevent antenna shaking or displacement during use. The cooperation between the flexible fastener and the PCB antenna body can also avoid overlapping with surrounding interference sources and affecting antenna performance, thereby improving antenna performance.

[0016] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0017] Reference Figures 1 to 3 , Figures 1 to 3 A specific embodiment of the PCB-embedded antenna assembly 10 of this utility model is shown. In the embodiment shown in the figures, the PCB-embedded antenna assembly 10 includes a PCB antenna body 11. Foam 12 is adhered to one side of the PCB antenna body 11, and a flexible fastener 13 for compression fitting into the housing of an external device is adhered to the other side, so that the PCB-embedded antenna assembly 10 is assembled into the housing in an interference fit. The inner side of the flexible fastener 13 is attached to the antenna 112 on the PCB antenna body 11. Understandably, the external device can be a handheld camera, a gimbal camera, or an electronic device with a relatively narrow installation space within the housing. Preferably, in this embodiment, the flexible fastener 13 can be made of silicone. In this utility model, through the cooperation of the foam 12 and the flexible fastener 13 with the PCB antenna body 11, the PCB-embedded antenna assembly 10 can be assembled into the housing of an external device (such as...) in an interference fit. Figure 3 As shown in the figure, the flexible fastener 13 is attached to the antenna 112 in the PCB built-in antenna assembly 10, which can make the position of the antenna 112 uniquely fixed and will not cause the antenna 112 to shake or shift during use. It can be used in scenarios with high requirements for the position of the antenna 112. In addition, the position of the antenna 112 will not be different due to different operators' assembly operations during the assembly process, which can ensure the consistency of the product. At the same time, it can also avoid overlapping with surrounding interference sources and affecting the performance of the antenna 112, thus improving the performance of the antenna 112.

[0018] In some embodiments, an adhesive layer 122 is provided on the side of the foam 12 away from the PCB antenna body 11. The PCB antenna body 11 can be fixed by the adhesive layer 122 on the foam 12, so that the PCB built-in antenna 112 body can be quickly attached to a designated position inside the housing. The fixing method is simple and convenient, the cost is low, and it does not affect the performance of the PCB antenna body 11 itself.

[0019] In some embodiments, the PCB antenna body 11 includes a PCB board 111 and an antenna 112 mounted on the PCB board 111. The antenna 112 includes a wire 1121 and a terminal 1122 connected to the wire 1121. The foam 12 and the flexible fastener 13 are respectively attached to both sides of the PCB board 111.

[0020] Specifically, in this embodiment, as Figure 1 and Figure 3As shown, the wire 1121 is located between the PCB board 111 and the flexible fixing member 13 and is attached to the flexible fixing member 13. Preferably, the inner side of the flexible fixing member 13 is provided with a wire groove 131 for placing the wire 1121 at the position of the wire 1121 to further fix the position of the antenna 112. The terminal 1122 is formed by bending upward from the end of the wire 1121 and passing through the PCB board 111 and located on the side of the PCB board 111 connected to the foam 12. The foam 12 is provided with a relief groove 121 at the position of the terminal 1122, and the terminal 1122 passes through the relief groove 121 to connect to the external circuit.

[0021] As can be seen from the above, the PCB board 111 of the PCB built-in antenna assembly 10 of this utility model is pre-installed with a flexible fastener 13 with a certain rigidity. When assembled in a narrow space, the PCB antenna body 11 can be quickly attached to the inner wall of the housing through the adhesive layer 122 on the outside of the foam 12 for fixation. This allows the PCB built-in antenna 112 body to be quickly attached to the designated position inside the housing. In combination with the flexible fastener 13, the PCB built-in antenna assembly 10 can be assembled into the housing of the external device in an interference fit manner, so that the position of the antenna 112 is uniquely fixed and will not cause the antenna 112 to shake or shift during use. It is suitable for scenarios with high requirements for the position of the antenna 112. Moreover, the position of the antenna 112 does not vary due to different operators' assembly operations during the assembly process, which can ensure product consistency. At the same time, it can also avoid overlapping with surrounding interference sources and affecting the performance of the antenna 112, thereby improving the performance of the antenna 112.

[0022] Understandably, this utility model can also provide a shooting device, which includes a lens module, a controller, a support arm for supporting the lens module, and the PCB-embedded antenna assembly 10 described in the above embodiments, wherein the support arm can be as follows: Figure 2 and Figure 3 The gimbal camera's support arm 20 shown can also be a handheld part for a handheld camera. The controller is connected to the lens module via the antenna 112 in the PCB-built antenna assembly 10 to control the lens module's operation. Figure 2 and Figure 3 The support arm 20 has an accommodating space 21. The PCB-embedded antenna assembly 10 is located in the accommodating space 21. The foam 12 is attached to one inner wall of the support arm 20 by an adhesive layer 122. The flexible fastener 13 is pressed and attached to another opposite inner wall of the support arm 20, so that the PCB-embedded antenna assembly 10 is assembled in the accommodating space 21 of the support arm 20 in an interference fit manner, so that the position of the antenna 112 is uniquely fixed.

[0023] The above preferred embodiments should be regarded as illustrative examples of the implementation of the present utility model. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present utility model should be considered within the scope of protection of this patent.
