It also includes a splicing mechanism 2, and the splicing mechanism 2 includes: a fixing block 21, an insert block 22, a limiting plate 23, a locking rod 25, a No. 1 limiting ring 26 and a reset spring 27.

[0037] Further, by Figure 1-Figure 3 As shown, in this embodiment, the fixing block 21 is fixed in the mounting opening 13, and a slot 211 is provided at one end of the fixing block 21, and a through hole 214 communicating with the slot 211 is provided on the fixing block 21, the plug-in block 22 is fixed to the end of the fixing block 21 away from the slot 211, and the plug-in block 22 can be embedded in the slot 211, and a locking groove 221 is provided on the plug-in block 22, and the limiting plate 23 is supported and fixed to the outer wall of the fixing block 21 by the mounting rod 24, and the locking rod 25 penetrates the limiting plate 23 and the through hole 214 and then is embedded in the locking groove 221, and a No. 1 limiting ring 26 is fixed on the locking rod 25, and a return spring 27 is sleeved on the locking rod 25 and is located between the limiting plate 23 and the No. 1 limiting ring 26. After adopting the above scheme, when in use, a circuit board body 1 can be fixed in the outer shell of the automobile blind spot lamp controller by conventional means, or two or more circuit board bodies 1 can be longitudinally spliced ​​and then fixed In the outer shell of the automobile blind spot lamp controller, when the circuit board body 1 is spliced, the staff pulls the locking rod 25 toward both sides at the same time. At this time, the reset spring 27 is in a contracted state. Then, the circuit board body 1 is lifted, and the slot 211 of the current circuit board body 1 is aligned with the plug-in block 22 of the lower circuit board body 1. Then, the plug-in block 22 is inserted into the slot 211, and the circuit board body 1 is pressed down. When the plug-in block 22 is fully inserted into the slot 211, the locking rod 25 is facing the locking groove 221. The locking rod 25 is released, and the reset spring 27 releases the elastic force to reset the locking rod 25. The locking rod 25 is inserted into the locking groove 221 to lock the circuit board body 1, so that the two circuit board bodies 1 can be stably spliced. On the premise of ensuring stable splicing, the safety of the splicing of the circuit board bodies 1 is improved, and the splicing and disassembly of the two circuit board bodies 1 can be completed by a single person, which is more convenient to use.

[0038] Preferably, by Figure 1-Figure 3As shown, in the present embodiment, the embedded end face of the locking rod 25 is an inclined surface. After adopting the above design, when splicing two circuit board bodies 1, there is no need to pull the locking rod 25 toward both sides at the same time. The slot 211 of the current circuit board body 1 is directly aligned with the plug-in block 22 of the lower circuit board body 1, and then the plug-in block 22 is inserted into the slot 211, and the circuit board body 1 is pressed down. The inclined surface of the locking rod 25 is subjected to force and a component force will be generated. Continuing to press down the upper circuit board body 1 will cause the locking rod 25 to automatically move toward the outside until the locking rod 25 moves to the position of the locking groove 221, making the splicing more convenient.

[0039] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a pull ring 28, which is fixed to one end of the locking rod 25 away from the fixing block 21. The setting of the pull ring 28 makes it easy to pull the locking rod 25 to move.

[0040] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a second limiting ring 29, which is fixed on the locking rod 25 near the pull ring 28, and is used to limit the movement range of the locking rod 25.

[0041] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, an oblique chamfer 222 is processed at one end of the insert block 22 away from the fixing block 21 . The oblique chamfer 222 has a guiding function, making it easy to insert the insert block 22 into the slot 211 .

[0042] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the plug block 22 abuts against the inner wall of the slot 211. Therefore, when the plug block 22 is inserted into the slot 211, the outer wall of the plug block 22 abuts against the inner wall of the slot 211, further improving the stability of the splicing of the two circuit board bodies 1 and avoiding lateral shaking.

[0043] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, the outer wall of the locking rod 25 abuts against the inner wall of the locking groove 221. Therefore, when the locking rod 25 is inserted into the locking groove 221, the outer wall of the locking rod 25 abuts against the inner wall of the locking groove 221, further improving the stability of the splicing of the two circuit board bodies 1 and avoiding lateral and longitudinal jitter.

[0044] Optionally, by Figure 1 and Figure 2As shown, in this embodiment, it also includes: an installation frame 212 and a double-sided tape 213. The installation frame 212 is fixed on the fixing block 21, and the double-sided tape 213 is bonded and fixed to the installation frame 212. The installation frame 212 is bonded and fixed to the circuit board body 1 by the double-sided tape 213. Therefore, after adopting the above scheme, the utility model uses the double-sided tape 213 to bond and fix the splicing mechanism 2, which is convenient for installation.

[0045] Components not described in detail herein are prior art.

[0046] Working principle and use process of the utility model: When the circuit board body 1 of the utility model is used, one circuit board body 1 can be fixed in the outer shell of the automobile blind spot light controller by conventional means, or two or more circuit board bodies 1 can be longitudinally spliced ​​and then fixed in the outer shell of the automobile blind spot light controller;

[0047] When splicing the circuit board body 1, the staff lifts the circuit board body 1, aligns the slot 211 of the current circuit board body 1 with the plug-in block 22 of the lower circuit board body 1, then inserts the plug-in block 22 into the slot 211, and presses down the circuit board body 1. The inclined surface of the locking rod 25 is subjected to force and a component force is generated. Continuing to press down the upper circuit board body 1 will cause the locking rod 25 to automatically move outward, and at this time, the return spring 27 is in a contracted state;

[0048] When the insert block 22 is fully inserted into the slot 211, the locking rod 25 is facing the locking groove 221, and the reset spring 27 releases the elastic force to reset the locking rod 25. The locking rod 25 is inserted into the locking groove 221 to lock the circuit board body 1, so that the two circuit board bodies 1 can be stably spliced. On the premise of ensuring the stability of the splicing, the safety of the splicing of the circuit board bodies 1 is improved, and the splicing of the two circuit board bodies 1 can be completed by a single person, which is more convenient to use.

[0049] When the upper circuit board body 1 needs to be disassembled, the staff uses the pull ring 28 to pull the locking rod 25 toward both sides at the same time. When the locking rod 25 is out of the locking groove 221, the circuit board body 1 can be lifted up. The disassembly is convenient and one person can complete the disassembly of the two circuit board bodies 1.
