Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to an automotive plug-in type multilayer circuit board. Background Technology

[0002] Automotive circuit boards are printed circuit boards specifically designed for automotive electronic systems. They serve as the "physical carrier" and "electrical connection hub" for automotive electronic components. Their core function is to mechanically fix and electrically connect electronic components such as chips, sensors, actuators, capacitors, and resistors through copper foil lines, pads, and other structures on the substrate, forming a complete circuit system. This system supports signal transmission, power distribution, and functional operation of various automotive electronic modules (such as the engine control unit (ECU), anti-lock braking system (ABS), airbag controller, and in-vehicle entertainment system).

[0003] However, existing automotive circuit boards have the following drawbacks: (1) Existing automotive circuit boards are easy to plug into, but the circuit board maintenance efficiency is weak. Since traditional circuit boards are fixed, if electronic components are damaged between multiple circuit boards, the maintenance process is more troublesome. Moreover, the device is easily damaged when disassembling the circuit board, resulting in a reduction in the circuit board maintenance efficiency. (2) Existing automotive circuit boards have weak stability and safety during transport. During transport, the circuit boards are easily damaged by collisions, causing signal transmission interruption or power supply abnormalities in the corresponding electronic systems, leading to subsequent functional failures. Utility Model Content

[0004] The purpose of this invention is to provide an automotive plug-in type multilayer circuit board to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive plug-in type multilayer circuit board, comprising: a first circuit board, a plug-in assembly, and a stabilizing assembly; a first telescopic rod is fixedly connected to the inner sidewall of the first circuit board; a first spring is sleeved on the outer surface of the first telescopic rod; a fixed frame is fixedly connected to one end of the first telescopic rod; a sliding rod is slidably connected inside the fixed frame; a second spring is sleeved on the lower surface of the sliding rod; a pull plate is fixedly connected to the top of the sliding rod; a limit block is fixedly connected to the bottom of the sliding rod; an insertion block is fixedly connected to the side of the fixed frame away from the first spring; a connecting block is inserted into the outer surface of the insertion block; and a second circuit board is fixedly connected to the top of the connecting block. The bottom of the first circuit board is provided with an anti-slip pad, and the bottom of the anti-slip pad is fixedly connected to a second telescopic rod. A third spring is sleeved on the outer surface of the second telescopic rod, and the bottom of the second telescopic rod is fixedly connected to an outer frame. An elastic sheet is fixedly connected to the inner side wall of the outer frame, and a clamping plate is fixedly connected to one end of the elastic sheet.

[0006] Optionally, one end of the first spring is fixedly connected to the inner side wall of the first circuit board, and the other end of the first spring is fixedly connected to one side of the surface of the fixed frame. Through the connection between the first spring, the first circuit board, and the fixed frame, the first circuit board supports and fixes one end of the first spring. When the first spring extends or retracts, it will drive the fixed frame to move together.

[0007] Optionally, the top of the second spring is fixedly connected to the inner top wall of the fixed frame, and the bottom of the second spring is fixedly connected to the top of the limiting block. Through the connection between the second spring, the fixed frame, and the limiting block, the fixed frame supports and fixes one end of the second spring. When the second spring extends or retracts, it will drive the limiting block to move together.

[0008] Optionally, the first circuit board has circular slots at its top four corners, and the second circuit board has limit rods fixedly connected to its bottom four corners. When the two circuit boards are connected, the limit rods at the bottom of one circuit board will be driven into the circular slots at the top of the other circuit board, and the limit rods will limit the connection process of the two circuit boards.

[0009] Optionally, the top of the third spring is fixedly connected to the bottom of the anti-slip pad, and the bottom of the third spring is fixedly connected to the inner bottom wall of the outer frame. Through the connection between the third spring, the anti-slip pad, and the outer frame, the outer frame supports and fixes the bottom of the third spring. When the third spring extends or retracts, it will drive the anti-slip pad to move together.

[0010] Optionally, the anti-slip mat is made of rubber. Because the anti-slip mat is made of rubber, it has anti-slip properties and can further improve the stability of the circuit board placement.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This automotive plug-in type multi-layer circuit board, through the setting of the plug-in assembly, when in use, pulling the pull plate causes the slide rod to slide upward and causes the second spring to retract. Then, the fixed frame moves laterally, causing the first telescopic rod and the first spring to retract. After inserting the connecting block into the first circuit board, the pull plate is released. The first spring rebounds until the fixed frame moves to a certain position. Then, the second spring rebounds and causes the limit block to insert into the first circuit board. The plug block is inserted into the connecting block, so that the first circuit board and the second circuit board are stably connected. The reverse operation can disassemble and maintain multiple circuit boards. It achieves the effect of convenient plugging and connecting circuit boards and improving the circuit board maintenance efficiency. It avoids the situation in traditional circuit boards that are fixed. If electronic components are damaged between multi-layer circuit boards, the maintenance process is more troublesome. Moreover, the device is easily damaged when disassembling circuit boards, which leads to a decrease in circuit board maintenance efficiency.

[0012] 2. This automotive plug-in type multilayer circuit board, through the setting of the stabilizing component, allows the circuit board to be placed on the anti-slip mat during use. At this time, the elastic sheet, due to its own elasticity, drives the clamping plate to clamp the side of the circuit board, maintaining the stability of the device during transportation. If the outer frame is impacted, the second telescopic rod and the third spring can reduce the vibration force and protect the circuit board. This achieves the effect of improving the stability and safety of the circuit board during transportation, avoiding the circuit board being easily damaged by collisions during transportation, which could lead to signal transmission interruption or power supply abnormality of the corresponding electronic system, causing subsequent functional failure.

[0015] 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.

[0016] Please see Figures 1-4 As shown, this utility model provides a technical solution: an automotive plug-in type multilayer circuit board, comprising: a first circuit board 1, a plug-in assembly 2, and a stabilizing assembly 3. A first telescopic rod 201 is fixedly connected to the inner sidewall of the first circuit board 1. A first spring 202 is sleeved on the outer surface of the first telescopic rod 201. A fixing frame 203 is fixedly connected to one end of the first telescopic rod 201. A sliding rod 204 is slidably connected inside the fixing frame 203. A second spring 205 is sleeved on the lower surface of the sliding rod 204. A pull plate 206 is fixedly connected to the top of the sliding rod 204. A limit block 207 is fixedly connected to the bottom of the sliding rod 204. An insertion block 208 is fixedly connected to the side of the fixing frame 203 away from the first spring 202. The outer surface of the insertion block 208 is inserted... A connecting block 209 is attached, and a second circuit board 210 is fixedly connected to the top of the connecting block 209. Pulling the pull plate 206 causes the slide rod 204 to slide upward and causes the second spring 205 to retract. Then, the fixed frame 203 moves laterally, causing the first telescopic rod 201 and the first spring 202 to retract. After the connecting block 209 is inserted into the first circuit board 1, the pull plate 206 is released. The first spring 202 rebounds until the fixed frame 203 moves to a certain position. Then, the second spring 205 rebounds, causing the limiting block 207 to be inserted into the first circuit board 1, and the insertion block 208 to be inserted into the connecting block 209, so that the first circuit board 1 and the second circuit board 210 are stably connected. The reverse operation can disassemble and maintain multiple sets of circuit boards. The slide rod 204 has a circular cross-section. The bottom of the first circuit board 1 is provided with an anti-slip pad 301. The bottom of the anti-slip pad 301 is fixedly connected to a second telescopic rod 302. A third spring 303 is sleeved on the outer surface of the second telescopic rod 302. The bottom of the second telescopic rod 302 is fixedly connected to an outer frame 304. An elastic sheet 305 is fixedly connected to the inner side wall of the outer frame 304. One end of the elastic sheet 305 is fixedly connected to a clamping plate 306. When the circuit board is placed on the anti-slip pad 301, the elastic sheet 305 drives the clamping plate 306 to clamp the side of the circuit board due to its own elasticity, so as to maintain the stability of the device during transportation. If the outer frame 304 is hit, the vibration force can be reduced by the setting of the second telescopic rod 302 and the third spring 303, thus protecting the circuit board. The elastic sheet 305 is made of 65Mn spring steel. One end of the first spring 202 is fixedly connected to the inner side wall of the first circuit board 1, and the other end of the first spring 202 is fixedly connected to one side of the surface of the fixed frame 203. Through the connection between the first spring 202, the first circuit board 1 and the fixed frame 203, the first circuit board 1 supports and fixes one end of the first spring 202. When the first spring 202 extends or retracts, it will drive the fixed frame 203 to move together. The top of the second spring 205 is fixedly connected to the inner top wall of the fixed frame 203, and the bottom of the second spring 205 is fixedly connected to the top of the limiting block 207. Through the connection between the second spring 205, the fixed frame 203 and the limiting block 207, the fixed frame 203 supports and fixes one end of the second spring 205. When the second spring 205 extends or retracts, it will drive the limiting block 207 to move together. The first circuit board 1 has circular slots 4 at the top four corners, and the second circuit board 210 has limit rods 5 fixedly connected to the bottom four corners. When the two circuit boards are connected, the limit rods 5 at the bottom of one circuit board will be driven into the circular slots 4 at the top of the other circuit board. At the same time, the limit rods 5 limit the connection process of the two circuit boards. The top of the third spring 303 is fixedly connected to the bottom of the anti-slip pad 301, and the bottom of the third spring 303 is fixedly connected to the inner bottom wall of the outer frame 304. Through the connection between the third spring 303, the anti-slip pad 301, and the outer frame 304, the outer frame 304 supports and fixes the bottom of the third spring 303. When the third spring 303 extends or retracts, it will drive the anti-slip pad 301 to move together. The anti-slip mat 301 is made of rubber. Because of its rubber material, the anti-slip mat 301 has anti-slip properties, which can further improve the stability of the circuit board placement.

[0017] In this invention, the working steps of the device are as follows: First step: Pull the pull plate 206 to drive the slide bar 204 to slide upward and cause the second spring 205 to retract. Then, move the fixed frame 203 laterally to drive the first telescopic rod 201 and the first spring 202 to retract. Insert the connecting block 209 into the first circuit board 1 and then release the pull plate 206. The first spring 202 rebounds until the fixed frame 203 moves to a certain position. Then, the second spring 205 rebounds to drive the limit block 207 to insert into the first circuit board 1, and the insertion block 208 to insert into the connecting block 209, so that the first circuit board 1 and the second circuit board 210 are stably connected. The reverse operation can be used to disassemble and maintain multiple sets of circuit boards.

[0018] The second step: Place the circuit board on the anti-slip mat 301. At this time, the elastic sheet 305 will cause the clamping plate 306 to clamp the side of the circuit board due to its own elasticity, so as to maintain the stability of the device during transportation. If the outer frame 304 is hit, the vibration force can be reduced by the second telescopic rod 302 and the third spring 303 to protect the circuit board.

[0019] The third step: The first spring 202 is connected to the first circuit board 1 and the fixing frame 203. The first circuit board 1 supports and fixes one end of the first spring 202. When the first spring 202 extends or retracts, it will drive the fixing frame 203 to move together. The second spring 205 is connected to the fixing frame 203 and the limiting block 207. The fixing frame 203 supports and fixes one end of the second spring 205. When the second spring 205 extends or retracts, it will drive the limiting block 207 to move together. When the two sets of circuit boards are connected, the limiting rod 5 at the bottom of one set of circuit boards will be inserted into the circular slot 4 at the top of the other set of circuit boards. At the same time, the limiting rod 5 limits the connection process of the two sets of circuit boards. The third spring 303 is connected to the anti-slip pad 301 and the outer frame 304. The outer frame 304 supports and fixes the bottom of the third spring 303. When the third spring 303 extends or retracts, it will drive the anti-slip pad 301 to move together. Since the anti-slip pad 301 is made of rubber, it has anti-slip properties and can further improve the stability of the circuit board placement.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
