[0002] In the car lamp system, PCB board bears various electronic components and circuits, which need to be accurately aligned and connected to ensure the normal operation of car lamp. Fixing PCB board can prevent it from moving or deforming inside the car lamp, thus maintaining its correct position and posture. In addition, vehicles will experience various shocks and collisions during driving, and if the PCB board is not fixed well, these shocks and collisions can cause the components on the PCB board to loosen, fall off or be damaged. Fixing PCB board can reduce this risk and improve the durability and reliability of car lamp.

[0003] The structural member for fixing PCB board in the prior art generally includes a one-piece clamping portion and a limiting portion. The clamping portion is provided with a clamping groove to clamp and press the PCB board, and the limiting portion is provided with a circular through hole for connecting the connecting portion of the reflector of the car lamp. Moreover, the bottom surface of the clamping portion is lower than that of the limiting portion, so that the impact force on the clamping portion and the limiting portion is different when the vehicle is in motion, which often causes the connection between the clamping portion and the limiting portion to break, and the PCB board to fall off, affecting the durability and reliability of the car lamp. In addition, the position of the circular through hole of the limiting portion is fixed, so the limiting portion can only limit the reflector at a single position, and cannot realize the universality of the structural member, increasing the manufacturing cost of the product.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The utility model provides an adjustable pressing structure for a PCB board on a vehicle lamp, such as Figures 1-4 As shown, the invention comprises a body 1, which includes a clamping portion 2 and a limiting portion 3. The clamping portion 2 and the limiting portion 3 are integrally formed. The clamping portion 2 is located on one side of the body 1, and a clamping slot 4 is provided at the bottom of the clamping portion 2. The clamping slot 4 is used to clamp and press the PCB board 5. The limiting portion 3 is located on the other side of the body 1. The limiting portion 3 is provided with an elongated through hole 6 with an elliptical cross section. The elongated through hole 6 passes through in the vertical direction and is used to connect to the reflector connecting portion 7 on the vehicle light. The limiting portion 3 is provided with three first limiting grooves 8 on the side walls on both sides of the elongated through hole 6 in the longitudinal direction, and the first limiting grooves 8 are used to clamp the first limiting rib 9 in the width direction of the reflector connecting portion 7. The limiting portion 3 is provided with a second limiting groove 10 on the side wall away from the clamping portion 2. The second limiting groove 10 is used to clamp the second limiting rib 11 in the longitudinal direction of the reflector connecting portion 7. The bottom surface of the clamping portion 2 and the bottom surface of the limiting portion 3 are located on the same horizontal plane. However, in the prior art, Figures 5-6As shown, the structural part for fixing the PCB board includes an integrally formed clamping part 2 and a limiting part 3. The clamping part 2 is provided with a clamping slot 4 for clamping and pressing the PCB board 5. The limiting part 3 is provided with a circular through hole 12 for connecting the reflector connecting part 7. The bottom surface of the clamping part 2 is lower than the bottom surface of the limiting part 3.

[0029] The present invention provides an adjustable clamping structure for a PCB board on a vehicle lamp. By providing a clamping slot 4 on a clamping portion 2, a PCB board 5 is clamped. By providing an elongated through-hole 6 on the clamping portion 2, a reflector connecting portion 7 can be inserted into the elongated through-hole 6. Simultaneously, a first limiting rib 9 of the reflector connecting portion 7 is correspondingly inserted into a first limiting groove 8, and a second limiting rib 11 of the reflector connecting portion 7 is inserted into a second limiting groove 10. The reflector connecting portion 7 is then fixed to the clamping portion 2 using connecting components such as bolts 18, thereby achieving a position-limited and secure connection of the reflector. Unlike prior art designs that only provide a single circular through-hole 12 and can only position the reflector in one position, the present invention provides three first limiting grooves 8, allowing the corresponding first limiting groove 8 to be selected according to the actual position of the reflector, thereby achieving position-limited connection of the reflector in three positions. This improves the versatility of the structural component and reduces product manufacturing costs.

[0030] Furthermore, in the prior art, the bottom surface of the clamping portion 2 is lower than the bottom surface of the limiting portion 3. Therefore, when the vehicle vibrates during driving, the impact forces on the clamping portion 2 and the limiting portion 3 are different, which may cause the intersection 17 of the clamping portion 2 and the limiting portion 3 to break, causing the PCB board 5 to fall off. However, in the present invention, the bottom surface of the clamping portion 2 and the bottom surface of the limiting portion 3 are located on the same horizontal plane. When the vehicle vibrates, the impact forces on the clamping portion 2 and the limiting portion 3 are the same, making the strength of the structural member body 1 higher, preventing the intersection 17 of the clamping portion 2 and the limiting portion 3 from breaking, preventing the PCB board 5 from falling off, and ensuring the durability and reliability of the headlight.

[0031] In this embodiment, anti-slip teeth 13 are provided on two opposite side walls of the card slot 4. By providing the anti-slip teeth 13, the friction between the card slot 4 and the PCB board 5 is increased, making the PCB board 5 less likely to fall off.

[0032] In this embodiment, a protrusion 14 is provided on the top surface of the main body 1. An elliptical mounting hole 15 is provided on one side of the protrusion 14, located above the stopper 3. The elliptical mounting hole 15 communicates with the elongated through-hole 6. Bolts 18 and other connecting components can pass through the elliptical mounting hole 15 to connect the stopper 3 to the reflector. The provision of the protrusion 14 also increases the strength of the top surface of the structural component main body 1, ensuring durability. A groove 16 is provided on one side of the protrusion 14, located above the clamping portion 2, to reduce the weight of the structural component main body 1 while ensuring wall thickness.

[0033] This utility model uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only used to help understand the method and core concept of this utility model. At the same time, for those skilled in the art, according to the concept of this utility model, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
