[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 3 The utility model provides the following technical solutions: a shock-resistant automobile turn signal circuit board, including a turn signal circuit board body 1, having four diagonally distributed mounting holes 11 on the turn signal circuit board body 1, and also including: an isolation support mechanism 2 and a buffer mechanism 3.

[0029] Further, by Figure 1-Figure 3As shown, in this embodiment, the isolation support mechanism 2 includes a support frame 21 fixed to the bottom surface of the turn signal circuit board body 1 and a flexible frame 22 fixed to the bottom end of the support frame 21. The buffer mechanism 3 includes an upper positioning plate 31, a lower positioning plate 32 and a buffer spring 33. The lower positioning plate 32 is fixed to the position corresponding to the mounting hole 11 on the turn signal circuit board body 1. The upper positioning plate 31 is fixed to the upper part of the lower positioning plate 32 by using a plurality of buffer springs 33 evenly spaced along the circumferential direction. After adopting the above scheme, when in use, the turn signal circuit board body 1 is fixed to the outer shell of the turn signal controller with bolts, and the bolts are passed through the upper positioning plate 31 and the lower positioning plate. After being threadedly connected to the mounting hole 11, the flexible frame 22 is screwed to the threaded hole reserved in the outer shell of the turn signal controller. At this time, the flexible frame 22 fits tightly against the inner wall of the outer shell of the turn signal controller, and the buffer spring 33 contracts, which can provide more stable support for the turn signal circuit board body 1, improve the overall structural strength of the turn signal circuit board body 1, avoid bending caused by vibration, and play a role in buffering and shock resistance, greatly improve safety, and extend the service life of the turn signal circuit board body 1. In addition, the reverse elastic force of the buffer spring 33 can also effectively increase the thread bite force, further improve the stability of the installation of the turn signal circuit board body 1, and avoid loosening of the bolts due to shaking.

[0030] It should be noted that, in this embodiment, the flexible frame 22 includes but is not limited to being made of rubber material.

[0031] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the support frame 21 is bonded and fixed to the bottom surface of the turn signal circuit board body 1, and the length and width of the support frame 21 are greater than the length and width of the turn signal circuit board body 1. After adopting the above scheme, the support frame 21 is bonded and fixed, which is convenient and stable to install. At the same time, the support frame 21 can provide safety protection for the turn signal circuit board body 1 to prevent objects from hitting the turn signal circuit board body 1 from the side, further improving safety.

[0032] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the flexible frame 22 is bonded and fixed to the bottom end of the support frame 21, which is convenient and stable to install.

[0033] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: double-sided tape 321, the double-sided tape 321 is bonded and fixed to the bottom surface of the lower positioning plate 32, and the lower positioning plate 32 is bonded and fixed to the turn signal circuit board body 1 by using the double-sided tape 321. After adopting the above scheme, the lower positioning plate 32 is bonded and fixed by using the double-sided tape 321, which is convenient and stable to install, and there is no need to open additional holes on the turn signal circuit board body 1, thereby ensuring the structural integrity of the turn signal circuit board body 1.

[0034] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a damping telescopic column 34, a plurality of damping telescopic columns 34 are fixed between the upper positioning plate 31 and the lower positioning plate 32 at equal intervals along the circumferential direction, and a buffer spring 33 is sleeved on the damping telescopic column 34. The damping telescopic column 34 is a telescopic structure composed of two hollow cylindrical components sleeved together, which has a damping effect. Together with the buffer spring 33, it has a better buffering and anti-vibration effect, and avoids the buffer spring 33 from constantly bouncing due to shaking.

[0035] Optionally, by Figure 1-Figure 3 As shown, in this embodiment, three damping telescopic columns 34 are fixed between the upper positioning plate 31 and the lower positioning plate 32 at equal intervals along the circumferential direction to ensure the stability of the connection between the upper positioning plate 31 and the lower positioning plate 32.

[0036] It should be noted that the above implementation scheme is only a preferred implementation scheme of the utility model and is not used to limit the utility model. In actual use, the damping telescopic column 34 can also be designed to have other numbers. In principle, the more damping telescopic columns 34 there are, the higher the stability of the connection between the upper positioning plate 31 and the lower positioning plate 32, but the cost is also higher. The three damping telescopic columns 34 form a three-point support, which can not only ensure stability but also effectively reduce costs.

[0037] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, ventilation holes 211 are evenly opened on the support frame 21. The ventilation holes 211 facilitate air circulation between the lower space of the turn signal circuit board body 1 and the outside world, which is beneficial to ventilation and heat dissipation of the turn signal circuit board body 1.

[0038] Components not described in detail herein are prior art.

[0040] At this time, the flexible frame 22 is closely attached to the inner wall of the turn signal controller housing, and the buffer spring 33 is contracted, which can provide more stable support for the turn signal circuit board body 1, improve the overall structural strength of the turn signal circuit board body 1, avoid bending due to vibration, and play a role in buffering and anti-vibration, greatly improving safety and extending the service life of the turn signal circuit board body 1;

[0041] In addition, the reverse elastic force of the buffer spring 33 can also effectively increase the thread bite force, further improve the installation stability of the turn signal circuit board body 1, and avoid loosening of the bolts due to shaking.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
