Description

Technical Field

[0001] This utility model relates to an automotive headlight circuit board. Background Technology

[0002] In automotive lighting systems, the circuit board, as the core control unit, directly affects the functionality of the lights and driving safety. Traditional automotive lighting circuit boards are typically fixed to the mounting area using rigid connections (such as direct bolt fastening). However, during vehicle operation, complex multi-directional vibration loads are easily transmitted directly to the circuit board body through the rigid connection structure, causing fatigue cracking of electronic component solder joints due to stress concentration, and even leading to faults such as open circuits and short circuits. In view of this, this utility model proposes an automotive lighting circuit board to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an automotive headlight circuit board to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automotive headlight circuit board includes a circuit board body, on which multiple sets of mounting slots are formed.

[0006] The mounting groove is provided with a connecting pipe, and the two ends of the connecting pipe are provided with connecting blocks. The outer wall of the connecting pipe is also provided with two sets of buffer rings. The two sets of buffer rings are matched with the two sets of connecting blocks. The buffer rings are set between the connecting blocks and the circuit board body. The connecting pipe is provided with a through connecting hole, and a connecting bolt is provided in the through connecting hole, so that the circuit board body is flexibly connected to the mounting area.

[0007] As an improvement to the above technical solution, the connecting pipe includes a first mounting pipe and a second mounting pipe, which are coaxially arranged.

[0008] The two sets of connecting blocks are respectively connected to the end faces of the first mounting tube and the second mounting tube.

[0009] As an improvement to the above technical solution, the first mounting tube is provided with a first connecting sleeve, the first connecting sleeve is provided with an external threaded wall, the second mounting tube is provided with a second connecting sleeve, the second connecting sleeve is provided with an internal threaded wall, and the external threaded wall and the internal threaded wall are threadedly engaged.

[0010] As an improvement to the above technical solution, the cross-section of the connecting block is hexagonal, and the connecting pipe is located at the center of the connecting block.

[0011] As an improvement to the above technical solution, the mounting groove is provided with an installation notch, and the width of the mounting groove is smaller than the diameter of the buffer ring.

[0012] As an improvement to the above technical solution, the buffer ring is made of rubber material.

[0013] As an improvement to the above technical solution, the connecting block has multiple sets of protrusions on one end face facing the buffer ring, and the buffer ring contacts the protrusions.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting a double buffer ring structure sleeved on the outer wall of the connecting pipe, a flexible support system is formed after connecting to the installation area. This effectively absorbs the multi-directional vibration energy during vehicle operation, transforming the rigid connection between the circuit board body and the installation area into elastic coupling. This avoids the impact of vibration during vehicle operation on the circuit board body and significantly reduces the risk of fatigue failure of electronic component solder joints.

[0016] By setting a double buffer ring structure for the sleeve and the outer coin of the connecting tube, stress can be avoided from being directly applied to the circuit board body when the connecting bolts are connected, thus preventing damage to the circuit board body caused by the connecting bolts and effectively improving the service life of the circuit board body.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] like Figure 1-5 As shown, this embodiment proposes an automotive headlight circuit board, including a circuit board body 10, on which multiple sets of mounting slots 11 are formed;

[0026] A connecting pipe 20 is provided in the mounting groove 11. Connecting blocks 40 are provided at both ends of the connecting pipe 20. Two sets of buffer rings 30 are also sleeved on the outer wall of the connecting pipe 20. The two sets of buffer rings 30 are matched with the two sets of connecting blocks 40. The buffer rings 30 are located between the connecting blocks 40 and the circuit board body 10. A through connecting hole 23 is provided on the connecting pipe 20. A connecting bolt is provided in the through connecting hole 23, so that the circuit board body 10 is flexibly connected to the mounting area.

[0027] In this case, the installation area is the location where the vehicle light circuit board is installed, and holes matching the positions of multiple sets of connecting through holes 23 are provided in this area. Then, a flexible connection is completed by connecting bolts to the holes.

[0028] In this embodiment, when the circuit board body 10 needs to be connected to the mounting area, a connecting tube 20 is placed in the mounting groove 11 of the circuit board body 10, and two sets of buffer rings 30 are respectively in contact with the upper and lower end faces of the circuit board body 10, until connecting tubes 20 are placed in multiple sets of mounting grooves 11. Then the circuit board body 10 is placed in the mounting area, and the connecting through hole 23 is aligned with the hole in the mounting area. Then connecting bolts are installed in the connecting through hole 23, so that the connecting bolts are connected to the hole in the mounting area, until connecting bolts are installed in multiple sets of connecting through holes 23, thereby completing the flexible mounting process of the circuit board body 10.

[0029] By setting a double buffer ring 30 structure sleeved on the outer wall of the connecting pipe 20, a flexible support system is formed after being connected to the installation area. This effectively absorbs the multi-directional vibration energy during vehicle operation, transforming the rigid connection between the circuit board body 10 and the installation area into elastic coupling. This avoids the vibration during vehicle operation from affecting the circuit board body 10, and at the same time significantly reduces the risk of fatigue failure of electronic component solder joints.

[0030] By setting a double buffer ring 30 structure between the sleeve and the outer coin of the connecting tube 20, stress can be avoided from being directly applied to the circuit board body 10 when the connecting bolts are connected, thus preventing damage to the circuit board body 10 caused by the connecting bolts and effectively improving the service life of the circuit board body 10.

[0031] Specifically, the connecting pipe 20 includes a first mounting pipe 21 and a second mounting pipe 22, which are coaxially arranged.

[0032] The two sets of connecting blocks 40 are respectively connected to the end faces of the first mounting tube 21 and the second mounting tube 22.

[0033] Specifically, the first mounting tube 21 is provided with a first connecting sleeve 212, the first connecting sleeve 212 is provided with an external threaded wall 211, the second mounting tube 22 is provided with a second connecting sleeve 222, the second connecting sleeve 222 is provided with an internal threaded wall 221, and the external threaded wall 211 and the internal threaded wall 221 are threadedly engaged.

[0034] In this embodiment, when the connecting pipe 20 is placed in the mounting groove 11, the first mounting pipe 21 can be rotated by the connecting block 40, which reduces the distance between the two sets of connecting blocks 40. This allows the connecting blocks 40 to press against the buffer ring 30, and the amount of distance reduction between the two sets of connecting blocks 40 can be precisely controlled. This enables the application of an adjustable axial preload to the buffer ring 30, which effectively improves the uniformity of contact pressure between the buffer ring 30 and the circuit board body 10, and enhances the stability of vibration energy absorption. At the same time, the thread self-locking characteristic keeps the preload constant, avoiding connection loosening caused by long-term vehicle vibration.

[0035] Of course, the adjustable design can be adjusted according to the actual installation situation, which significantly improves the assembly accuracy of the installation structure, ensures that the flexible support system can maintain optimal buffering performance in different environments, and further reduces the risk of failure of electronic components due to stress concentration.

[0036] Specifically, the cross-section of the connecting block 40 is hexagonal, and the connecting pipe 20 is located at the center of the connecting block 40.

[0037] In this embodiment, the connecting block 40 with a cross-section of equal hexagons can be easily rotated by tools such as wrenches.

[0038] Specifically, the mounting groove 11 is provided with a mounting notch 12, and the width of the mounting groove 11 is smaller than the diameter of the buffer ring 30.

[0039] In this embodiment, the installation notch 12 facilitates the connection pipe 20 to enter the installation groove 11.

[0040] Specifically, the buffer ring 30 is made of rubber material.

[0041] Specifically, the connecting block 40 has multiple sets of protrusions on one end face facing the buffer ring 30, and the buffer ring 30 contacts the protrusions.

[0042] In this embodiment, by providing multiple sets of protrusions on the end face of the connecting block 40 facing the buffer ring 30, a multi-point friction enhancement structure is formed. The protrusions form a local embedded contact with the surface of the buffer ring 30, which significantly increases the friction coefficient of the contact surface and suppresses the relative slippage between the buffer ring 30 and the connecting block 40 through the mechanical interlocking effect.

[0043] This design effectively improves the deformation recovery accuracy of the buffer ring 30 under vibration environment, and avoids the buffer ring 30 from shifting or loosening due to insufficient friction. At the same time, the discrete layout of the protrusions can disperse the stress on the contact surface, reduce the risk of local wear of the buffer ring 30, and extend the service life of the elastic element.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
