DETAILED DESCRIPTION

[0037] 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.

[0038] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a car turn signal circuit board that is easy to disassemble and maintain, including a circuit board body 1, and also includes: a fixed base plate 2, an L-shaped positioning angle 3, a clamping mechanism 4 and a flexible support mechanism 5.

[0039] Further, by Figure 1-Figure 4 As shown, in this embodiment, a fixing hole 21 is provided on the fixed substrate 2, four L-shaped positioning corners 3 are diagonally fixed on the top surface of the fixed substrate 2, and are used to position the four corners of the circuit board body 1, two sets of clamping mechanisms 4 are symmetrically fixed on the fixed substrate 2, and the clamping mechanism 4 includes a fixing plate 41 and a clamping rod 42, the fixing plate 41 is fixed on the fixed substrate 2, the clamping rod 42 is elastically connected to the fixing plate 41, and the cross-section of the clamping rod 42 is a triangular structure, two sets of flexible support mechanisms 5 are symmetrically fixed on the fixed substrate 2, and are used to support the circuit board body 1. After adopting the above scheme, when in use, the fixed substrate 2 is first fixed in the housing of the automobile turn signal controller by conventional means. Since the fixed substrate 2 is pre-set with a fixing hole 21, the fixed substrate 2 can be fixed and installed by bolts. After the fixed substrate 2 is installed and stably, the four L-shaped positioning angle wraps 3 are used to locate the four corners of the circuit board body 1 to locate the installation position of the circuit board body 1 and avoid horizontal displacement of the circuit board body 1. Then, the circuit board body 1 is pressed down. Since the clamping rod 42 is elastically connected to the fixed plate 41, and the cross-section of the clamping rod 42 is a triangular structure, when the inclined surface of the clamping rod 42 is stressed, a component force will be generated to move the clamping rod 42 toward the outside for avoidance until the circuit board body 1 passes over the clamping rod 42. At this time, the clamping rod 42 is reset, and the circuit board body 1 is supported from below by the flexible support mechanism 5. At the same time, the circuit board body 1 is clamped from above by the clamping rod 42. Under the premise of ensuring the installation stability of the circuit board body 1, the safety is also greatly improved, and it is also convenient for disassembly and maintenance, and the disassembly and assembly efficiency is high.

[0040] Optionally, by Figure 1-Figure 3 As shown, in this embodiment, the clamping mechanism 4 also includes: a mounting rod 43 and a reset spring 44. The mounting rod 43 is fixed on the clamping rod 42 and passes through the fixed plate 41. The reset spring 44 is sleeved on the mounting rod 43 and is located between the fixed plate 41 and the clamping rod 42. After adopting the above scheme, when the inclined surface of the clamping rod 42 is subjected to force, a component force will be generated to cause the clamping rod 42 to move toward the outside to avoid it, and the reset spring 44 will shrink.

[0041] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, the clamping mechanism 4 further includes: a limit plate 431 , which is fixed to one end of the mounting rod 43 away from the clamping rod 42 , and the movement range of the clamping rod 42 is limited by the set limit plate 431 .

[0042] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, three equally spaced mounting rods 43 are fixed on the clamping rod 42 to improve the installation stability of the clamping rod 42 and prevent the clamping rod 42 from rotating to affect the clamping effect.

[0043] It should be noted that the above embodiments are only exemplary descriptions of the present invention and are not intended to limit the present invention. In actual use, the clamping rods 42 may also be installed in other numbers, but in theory the number of installed clamping rods 42 should be at least two to prevent the rotation of the clamping rods 42 from affecting the clamping effect.

[0044] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the flexible support mechanism 5 includes: an upper support plate 51, a lower support plate 52, a damping telescopic column 53 and a telescopic spring 54. The lower support plate 52 is fixed on the fixed base plate 2, and the two damping telescopic columns 53 are symmetrically fixed between the upper support plate 51 and the lower support plate 52. The telescopic spring 54 is sleeved on the damping telescopic column 53 and is located between the upper support plate 51 and the lower support plate 52. After adopting the above scheme, the elastic force of the telescopic spring 54 can push the upper support plate 51 to stably support the circuit board body 1, and cooperate with the clamping rod 42 to present a state of clamping the circuit board body 1, thereby ensuring the stability of the installation of the circuit board body 1.

[0045] It should be noted that, in the present embodiment, the damping telescopic column 53 is a telescopic structure composed of two hollow cylindrical members sleeved together, which has a damping effect and can also play a role in buffering and anti-vibration for the circuit board body 1 in conjunction with the telescopic spring 54 .

[0046] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: a flexible pad 511, which is bonded and fixed to the top surface of the upper support plate 51, and the flexible pad 511 is flexible. When the upper support plate 51 and the clamping rod 42 clamp the circuit board body 1, the flexible pad 511 contracts to ensure the safety of the circuit board body 1 and avoid mechanical damage caused by rigid clamping.

[0047] It should be noted that, in the present embodiment, the flexible pad 511 includes but is not limited to being made of rubber material, and in actual use, the flexible pad 511 is also fixed to the bottom surface of the pressing rod 42 .

[0048] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: double-sided tape 521, the double-sided tape 521 is bonded and fixed to the bottom surface of the lower support plate 52, and the lower support plate 52 is bonded and fixed to the fixed base plate 2 using the double-sided tape 521, which is easy to install, and the initial installation position of the flexible support mechanism 5 can be adjusted at will to meet different usage needs.

[0049] Components not described in detail herein are prior art.

[0050] Working principle and use process of the utility model: When the circuit board body 1 of the utility model is used, the fixed substrate 2 is first fixed in the housing of the automobile turn signal controller by conventional means. After the fixed substrate 2 is installed stably, the four corners of the circuit board body 1 are positioned by four L-shaped positioning angle wraps 3 to locate the installation position of the circuit board body 1 and avoid horizontal displacement of the circuit board body 1;

[0051] Then, the circuit board body 1 is pressed down. Since the pressing rod 42 is elastically connected to the fixing plate 41 and the cross section of the pressing rod 42 is a triangular structure, when the inclined surface of the pressing rod 42 is stressed, a component force is generated to make the pressing rod 42 move outward to avoid the circuit board body 1. The reset spring 44 contracts until the circuit board body 1 passes over the pressing rod 42. At this time, the reset spring 44 releases its elastic force to reset the pressing rod 42.

[0052] The elastic force of the telescopic spring 54 can push the upper support plate 51 to stably support the circuit board body 1, and cooperate with the clamping rod 42 to clamp the circuit board body 1, thereby ensuring the stability of the installation of the circuit board body 1. Under the premise of ensuring the stability of the installation of the circuit board body 1, the safety is greatly improved, and it is also convenient for disassembly and maintenance, and the disassembly and assembly efficiency is high;

[0053] When disassembling the circuit board body 1, the two clamping rods 42 are pushed outward. After the clamping rods 42 are separated from the circuit board body 1, the elastic force of the telescopic spring 54 can push the upper support plate 51 upward, and the circuit board body 1 is lifted up by the upper support plate 51, which makes disassembly and maintenance convenient.

[0054] 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. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
