[0041] like Figure 1-Figure 4As shown, this embodiment provides a circuit board mounting structure for fixing and installing a circuit board 100. The circuit board mounting structure includes a circuit board support 1 and a decorative ring 2. The circuit board support 1 is provided with a slot 11 and a first fixing portion 12. One end of the circuit board 100 is fixed in the slot 11. The decorative ring 2 is provided with a threaded opening 21 and a second fixing portion 22. The other end of the circuit board 100 is fixed in the threaded opening 21. The second fixing portion 22 can be fixedly connected to the first fixing portion 12 to fix the circuit board support 1 and the decorative ring 2. The circuit board mounting structure provided in this embodiment is achieved by fixing the circuit board 100 between the slot 11 of the circuit board support 1 and the threaded opening 21 of the decorative ring 2, and then fixing the circuit board support 1 and the decorative ring 2 to achieve fixed installation of the circuit board 100. This installation method does not require threaded holes in the circuit board 100, can avoid damage to the circuit board 100, achieve stable installation of the circuit board 100, and improve the stability of the circuit board 100.

[0042] The principle of fixing circuit board 100 with circuit board support 1 and decorative ring 2 indicates that circuit board 100 is in a horizontal position, with one end of circuit board 100 retained within slot 11 of circuit board support 1 and the other end within notch 21 of decorative ring 2. Circuit board 100 is clamped in the horizontal and left-right directions by circuit board support 1 and decorative ring 2, while being vertically limited by slot 11 and notch 21.

[0043] Optionally, an LED lamp 200 is mounted on the circuit board 100 to achieve the lighting effect of a headlight. In this embodiment, the LED lamp 200 is square and has antennae, which are soldered to the circuit board 100 via a specific medium. Of course, in other embodiments, other light-emitting elements can be mounted on the circuit board 100 to achieve the lighting effect of a headlight, but these examples are not further detailed here.

[0044] For example, Figure 1-Figure 2 As shown, in this embodiment, one decorative ring 2 cooperates with two circuit board supports 1 to secure two circuit boards 100. Of course, in other embodiments, one decorative ring 2 may cooperate with one circuit board support 1 to secure one circuit board 100, or one decorative ring 2 may cooperate with three circuit board supports 1 to secure three circuit boards 100. The specific design can be based on actual needs and will not be further illustrated here.

[0045] In order to achieve stable installation of the circuit board 100, as Figure 3As shown, two first fixing portions 12 are provided on either side of the slot 11, and two second fixing portions 22 are provided on either side of the threaded opening 21, with the second fixing portions 22 corresponding one to one with the first fixing portions 12. Specifically, the circuit board 100 is clamped between the circuit board support 1 and the decorative ring 2, and then the circuit board support 1 and the decorative ring 2 are fixed on the upper and lower sides of the circuit board 100. This ensures that the circuit board 100 is stably installed, ensuring that the circuit board 100 vibrates minimally under the action of the circuit board support 1 and the decorative ring 2 when the vehicle is driving, thereby enhancing the stability of the LED lamp 200's light emission.

[0046] Preferably, if Figure 3 Combine Figure 4 As shown, a fixing groove 121 is provided on the first fixing portion 12, and a fixing column 221 is provided on the second fixing portion 22. The fixing column 221 can be clamped in the fixing groove 121. Through the cooperation between the fixing column 221 and the fixing groove 121, the relative displacement of the circuit board support 1 and the decorative ring 2 can be ensured to remain unchanged, thereby ensuring the stability of the circuit board 100.

[0047] For example, in this embodiment, a threaded hole is provided at the end of the fixing column 221, and a through hole is provided at the bottom of the fixing groove 121. The bolt passes through the through hole of the fixing groove 121 and is threadedly connected to the fixing column 221 to achieve a fixed connection between the circuit board support 1 and the decorative ring 2.

[0048] Preferably, if Figure 5 Combine Figure 6 As shown, a limiting card plate 23 is provided inside the tooth mouth 21, and a limiting card slot 231 is provided on the limiting card plate 23. The width of the limiting card slot 231 is adapted to the thickness of the circuit board 100. The circuit board 100 can be clamped in the limiting card slot 231 to further limit the circuit board 100 in the vertical direction.

[0049] In order to limit the position of the circuit board 100 in the horizontal front-back direction, as shown in FIG. Figure 7 Combine Figure 6 As shown, the circuit board 100 is provided with a first limiting groove 101. The thickness of the limiting card plate 23 is adapted to the width of the first limiting groove 101, and the limiting card plate 23 can be fixed in the first limiting groove 101. In short, the first limiting groove 101 of the circuit board 100 is fixed on both sides of the limiting card plate 23 to limit the circuit board 100 in the horizontal front-to-back direction; the limiting card slots 231 on the limiting card plate 23 are fixed on the upper and lower side surfaces of the circuit board 100 to limit the circuit board 100 in the vertical direction.

[0050] Furthermore, a plurality of limiting clamps 23 are arranged along the extending direction of the thread opening 21. Accordingly, a plurality of first limiting grooves 101 are provided on the circuit board 100 so that the first limiting grooves 101 are matched with the limiting clamps 23 one by one.

[0051] For example, in this embodiment, Figure 6 As shown, there are two limit clamps 23 and two first limit slots 101 on the circuit board 100 , and the first limit slots 101 match the limit clamps 23 one by one.

[0052] Optionally, in order to further limit the position of the circuit board 100 in the horizontal front-back direction, as shown in FIG. Figure 7 Combine Figure 3 As shown, the card slot 11 passes through the circuit board support 1 in its length direction, and a second limiting slot 102 is provided on the circuit board 100. The card slot 11 can cooperate with the second limiting slot 102 so that the groove walls on both sides of the second limiting slot 102 abut against the two side walls of the circuit board support 1. Specifically, as Figure 2 As shown, the second limiting groove 102 on the circuit board 100 cooperates with the clamping groove 11 on the circuit board support 1, so that the circuit board support 1 limits the circuit board 100 in four directions: up, down, left, and right.

[0053] Furthermore, the opening end of the second limiting groove 102 on the circuit board 100 is in an arc shape, so that the circuit board 100 can be easily locked in the locking groove 11 .

[0054] Preferably, if Figure 8 As shown, to facilitate the installation of circuit board 100, the angle between the upper wall of thread opening 21 and the horizontal plane is θ1, and the range of θ1 is 15° to 30°. That is, thread opening 21 is flared to facilitate the insertion of circuit board 100 into thread opening 21. Furthermore, the angle between the lower wall of thread opening 21 and the horizontal plane is θ2, and the range of θ2 is 15° to 30°. Exemplarily, the upper and lower walls of thread opening 21 are arranged symmetrically. In this case, the circuit board 100 is fixed by the cooperation of the limiting slot 231 of the limiting clip 23 and the first limiting slot 101 on the circuit board 100.

[0055] Considering the thickness of the circuit board 100, the minimum width of the threaded opening 21 is d, and the range of d is 1.6 mm to 3.4 mm. Specifically, the width of the position limiting slot 231 is 1.6 mm to 3.4 mm.

[0056] Furthermore, the width of the first limiting groove 101 on the circuit board 100 ranges from 1 mm to 3 mm, and is mainly designed based on the thickness of the limiting clamping plate 23 .

[0057] This embodiment also provides a circuit board installation method, comprising the following steps:

[0058] One end of the circuit board 100 is clamped into the threaded opening 21 of the decorative ring 2;

[0059] Use the card slot 11 on the circuit board support 1 to clamp the circuit board support 1 to the other end of the circuit board 100, so that the circuit board 100 is clamped between the circuit board support 1 and the decorative ring 2;

[0060] The first fixing portion 12 on the circuit board support 1 is fixedly connected to the second fixing portion 22 on the decorative ring 2 .

[0061] The circuit board installation method provided in this embodiment, by applying the above-mentioned circuit board installation structure, installs and fixes the LED lamp 200 on the circuit board 100, which can achieve stable installation of the LED circuit board and improve the stability of the LED circuit board.

[0062] Specifically, one end of the circuit board 100 is positioned within the groove 21 of the decorative ring 2, and the first retaining groove 101 on the circuit board 100 engages with the retaining groove 231 on the retaining plate 23 within the groove 21. The retaining groove 11 of the circuit board support 1 mates with the second retaining groove 102 on the circuit board 100. Bolts securely connect the first fixing portion 12 on the circuit board support 1 to the second fixing portion 22 on the decorative ring 2.

[0063] This circuit board installation method changes from the previous vertical fixation to parallel pressing, so that the circuit board support 1 can fit tightly with the circuit board 100 without sliding. At the same time, the two ends of the circuit board support 1 are set to a symmetrical structure, which makes it have better rigidity and long service life. When the car is driving, the vibration amplitude of the LED light source of the taillight is small, and the stability is better.

[0064] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
