[0004] However, there are still the following problems. When an accident such as a vehicle collision occurs, it may cause the low-voltage line connectors to loosen, resulting in poor contact and further causing a short circuit. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a low-voltage communication wiring harness for an automotive electronic system to solve the problems existing in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A low-voltage communication wire harness for an automotive electronic system, including a fixing member locking device. Inside the fixing member locking device, there is a joint reinforcement device. The wire harness assembly is movably sleeved inside the joint reinforcement device. The top of the fixing member locking device is fixedly connected with a vibration trigger device. The fixing member locking device includes an enclosing housing. A partition is welded to the inner wall of the enclosing housing and is perpendicular to the inner wall of the enclosing housing. A circular hole is provided in the middle of the front of the partition. Two first springs are welded to both the front and back of the partition. The front end and the rear end of the top of the enclosing housing are both bolted with fixing plates. On the opposite sides of the two fixing plates, second springs are fixedly connected. Inside the two fixing plates, piston assemblies are fixedly sleeved. The piston assemblies are located inside the second springs. At the bottom of one end of the two piston assemblies, air pipes are connected by pipelines. One end of the two air pipes is connected by pipelines to a locking component. One end of the locking component passes through the side wall of the enclosing housing. The joint reinforcement device includes a sliding component. On both sides of the sliding component, connecting blocks are fixedly connected. On the front of the two connecting blocks, connecting rods are fixedly connected. One end of each of the two connecting rods is fixedly connected with a magnet block. The sliding component includes a wire harness collar. An annular groove is provided inside the wire harness collar. Five fixing rod frames are fixedly connected to the inside of the wire harness collar. At the top of the five fixing rod frames, balls are rotatably sleeved. The vibration trigger device includes a trigger tube component. At both ends of the trigger tube component, connecting strips are fixedly connected. One end of each of the two connecting strips is fixedly connected with a strip plate. Square holes are provided at one end of the two strip plates. Inside the two square holes, piston assemblies are connected by mortise and tenon joints. The bottom of the trigger tube component is fixedly connected to the top of the enclosing housing.

[0007] Further, the piston assembly includes a mortise and tenon block. The bottom end of the mortise and tenon block is fixedly connected with a first piston. On both sides of the top of the first piston, cross blocks are fixedly connected. The side of the first piston is movably sleeved with a first air cylinder.

[0008] Further, the locking component includes a protective housing. On one side of the protective housing, a second air cylinder is fixedly sleeved. The side of one end of the second air cylinder is connected by a pipeline to an air pipe. Inside the second air cylinder, a second piston is movably sleeved.

[0009] Further, a third spring is fixedly connected to the inner wall of one side of the protective housing. The second piston is located inside the third spring. One end of the second piston is fixedly connected with a locking pin.

[0010] Further, the trigger tube component includes a circular tube. At both ends of the circular tube, circular plates are fixedly connected. Inside the two circular plates, impact rods are movably sleeved.

[0011] Further, steel balls are placed in the inner cavity of the circular tube.

[0012] Further, the wire harness assembly includes a low-voltage wire harness. Both ends of the low-voltage wire harness are electrically connected to connector housings. Positioning blocks are fixedly connected to the tops of the two connector housings, and trapezoidal grooves are provided on the fronts of the two positioning blocks.

[0013] Further, connecting heads are electrically connected to the inner walls of the backs of the two connector housings, and three electrode rods are electrically connected to the inner walls of the backs of the two connecting heads.

[0014] Technical effects and advantages of the present invention:

[0015] 1. By providing a joint reinforcement device, the present invention utilizes the thrust generated instantaneously when the spring is released to push the joint reinforcement device towards the wire harness joint. Then, the friction between the sliding component and the wire harness is reduced by the ball, enabling the joint reinforcement device to reach the wire harness joint. Additionally, a magnet is provided in the joint reinforcement device. When the joint reinforcement device contacts the wire harness joint, since the interface connecting the wire harness joint is mainly made of copper and its alloys, it will be adsorbed by the magnet, thereby playing a role in strengthening the connection between the wire harness joint and the interface. This avoids the problem that the low-voltage line joint becomes loose and has poor contact due to the vehicle colliding or other severe vibrations, which may lead to a short-circuit problem. It is beneficial to improve the quality and reliability of the low-voltage wire harness and also enhance the efficiency and safety of the automotive electronic system.

[0016] 2. By providing a vibration trigger device, when the vehicle body shakes violently, the steel balls in the circular tube will roll back and forth along the inner wall of the circular tube. When the steel balls roll to one end of the circular tube, the steel balls have a certain kinetic energy. When the steel balls impact the short rod, the kinetic energy of the steel balls is transmitted to the short rod, causing the short rod to displace. One end of the short rod is connected to a strip plate, and a square hole is provided at one end of the strip plate. The protruding part of the tenon and mortise block of the piston assembly is stuck at the edge of the square hole so that it will not move forward under the action of the spring. When the short rod displaces, the strip plate displaces in the same direction, and thus the tenon and mortise block is located in the square hole, and the strip plate cannot block the tenon and mortise block. Under the force of the spring, the piston assembly moves forward, thereby forming a negative pressure in the first air cylinder. Due to the transmission of the air pipe, a negative pressure is also formed in the second air cylinder. The negative pressure contracts the second piston. One end of the second piston is fixedly connected to a locking pin, and the locking pin also displaces towards the second air cylinder, thereby releasing the lock of the joint reinforcement device. When the steel balls roll towards the other end of the circular tube, similarly, this process is beneficial to improve the joint connection quality and reliability of the low-voltage wire harness.

[0027] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and a low-voltage communication wire harness of an automotive electronic system related to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0028] Refer to Figure 1 , the present invention provides a low - voltage communication wire harness for an automotive electronic system, including a fixing part locking device 1. Inside the fixing part locking device 1, there is a joint reinforcement device 2. The wire harness assembly 4 is movably sleeved inside the joint reinforcement device 2. The top of the fixing part locking device 1 is fixedly connected to a vibration trigger device 3.

[0029] In this embodiment, it needs to be specifically supplemented and explained that there are two joint reinforcement devices 2 in the inner cavity of the fixing part locking device 1. The joint reinforcement device 2 and the vibration trigger device 3 are temporarily connected directly through a mortise - tenon structure. The joint reinforcement device 2 is beneficial to improving the quality and reliability of the low - voltage wire harness, and also improves the efficiency and safety of the automotive electronic system. The vibration trigger device 3 is beneficial to improving the joint connection quality and reliability of the low - voltage wire harness. The specific structures and working principles of the above components will be described in detail later.

[0030] Refer to Figure 2 , the fixing part locking device 1 includes an enclosing shell 101. A partition 102 is welded to the inner wall of the enclosing shell 101 and the partition 102 is perpendicular to the inner wall of the enclosing shell 101. There is a round hole in the middle of the front side of the partition 102. Two first springs 103 are welded to both the front and back sides of the partition 102. The front end and the rear end of the top of the enclosing shell 101 are bolt - connected with fixing plates 104. On the opposite sides of the two fixing plates 104, second springs 105 are fixedly connected. A piston assembly 106 is fixedly sleeved inside both the fixing plates 104. The piston assembly 106 is located inside the second spring 105. The bottom ends of one ends of the two piston assemblies 106 are connected by pipes to air pipes 107. One ends of the two air pipes 107 are connected by pipes to a locking component 108. One end of the locking component 108 passes through the side wall of the enclosing shell 101.

[0031] In this embodiment, it needs to be specifically supplemented and explained that the two first springs 103 on the front and back sides of the partition 102 are located on both sides of the round hole of the partition 102.

[0032] Refer to Figure 3 , the piston assembly 106 includes a mortise - tenon block 1061. The bottom end of the mortise - tenon block 1061 is fixedly connected to a first piston 1062. On both sides of the top end of the first piston 1062, cross - blocks 1063 are fixedly connected. The side of the first piston 1062 is movably sleeved with a first air cylinder 1064.

[0033] In this embodiment, it needs to be specifically supplemented and explained that the cross - blocks 1063 are located outside the first air cylinder 1064. In actual use, the cross - blocks 1063 will squeeze the second spring 105, and the first air cylinder 1064 is located inside the second spring 105.

[0034] Refer to Figure 4 Figure 4 , the locking component 108 includes a protective housing 1081. A second air cylinder 1082 is fixedly sleeved on one side of the protective housing 1081. A trachea 107 is connected to the side of one end of the second air cylinder 1082 through a pipeline. A second piston 1083 is movably sleeved inside the second air cylinder 1082. A third spring 1084 is fixedly connected to the inner wall on one side of the protective housing 1081. The second piston 1083 is located inside the third spring 1084. One end of the second piston 1083 is fixedly connected to a locking pin 1085.

[0035] Refer to Figure 5 Figure 5 , the joint reinforcement device 2 includes a sliding component 201. Connecting blocks 202 are fixedly connected to both sides of the sliding component 201. Connecting rods 203 are fixedly connected to the fronts of the two connecting blocks 202. Magnet blocks 204 are fixedly connected to one ends of the two connecting rods 203.

[0036] It should be specifically supplemented in this embodiment that the connecting block 202 presses the first spring 103 and is in a stable state through the locking pin 1085.

[0037] Refer to Figure 6 Figure 6 , the sliding component 201 includes a wire harness collar 2011. An annular groove is provided inside the wire harness collar 2011. Five fixed rod frames 2012 are fixedly connected to the inside of the wire harness collar 2011. Ball bearings 2013 are rotatably sleeved on the tops of the five fixed rod frames 2012.

[0038] It should be specifically supplemented in this embodiment that the annular space formed by the five ball bearings 2013 is used to place the wire harness. When the sliding component 201 moves, the ball bearings 2013 directly roll on the outer surface of the wire harness, making the movement of the sliding component 201 smoother. Using the thrust released by the first spring 103 instantaneously, the joint reinforcement device 2 is pushed towards the wire harness joint. Then, the friction between the sliding component and the wire harness is reduced through the ball bearings 2013, enabling the joint reinforcement device 2 to reach the wire harness joint. Additionally, a magnet block 204 is provided on the joint reinforcement device. When the sliding component 201 contacts the wire harness joint, since the interface connecting the wire harness joint is mainly made of copper and its alloys, it will be adsorbed by the magnet block 204, thereby playing a role in strengthening the connection between the wire harness joint and the interface. This avoids the occurrence of problems such as loosening and poor contact of the low-voltage line connection head due to vehicle collisions or other violent vibrations, which may lead to short circuits. It is beneficial to improve the quality and reliability of the low-voltage wire harness and also improve the efficiency and safety of the automotive electronic system.

[0039] Refer to Figure 7, the vibration trigger device 3 includes a trigger tube assembly 301. Both ends of the trigger tube assembly 301 are fixedly connected with connecting bars 302. One end of each of the two connecting bars 302 is fixedly connected with a strip plate 303. One end of each of the two strip plates 303 is provided with a square hole 304. A piston assembly 106 is connected to the inner sides of the two square holes 304 by mortise and tenon joints. The bottom of the trigger tube assembly 301 is fixedly connected to the top of the surrounding housing 101.

[0040] In this embodiment, it should be specifically supplemented that the two connecting bars 302 are respectively connected to the front and rear of the trigger tube assembly 301, specifically as Figure 7 shown.

[0041] Refer to Figure 8 , the trigger tube assembly 301 includes a circular tube 3011. Both ends of the circular tube 3011 are fixedly connected with circular plates 3012. Impact rods 3013 are movably sleeved inside the two circular plates 3012. Steel balls 3014 are placed in the inner cavity of the circular tube 3011.

[0042] In this embodiment, it should be specifically supplemented that when the environment where the trigger tube assembly 301 is located undergoes violent shaking, the steel balls 3014 roll to both ends of the circular tube 3011 and impact the impact rods 3013 to displace them. When the vehicle body undergoes violent shaking, the steel balls 3014 in the circular tube 3011 will roll back and forth along the inner wall of the circular tube 3011. When the steel ball rolls to one end of the circular tube 3011, the steel ball 3014 has a certain kinetic energy. When the steel ball 3014 impacts the impact rod 3013, the kinetic energy of the steel ball 3014 is transmitted to the impact rod 3013, causing the impact rod 3013 to displace. One end of the impact rod 3013 is connected to a strip plate 303. A square hole 304 is provided at one end of the strip plate 303. The protruding part of the mortise and tenon block 1061 of the piston assembly 106 is stuck at the edge of the square hole 304 so that it will not move forward under the action of the second spring 105. When the impact rod 3013 displaces, the strip plate 303 displaces in the same direction, and then the mortise and tenon block 1061 is located in the square hole 304, and the strip plate 303 cannot hold the mortise and tenon block 1061. Under the force of the second spring 105, the piston assembly 106 moves forward, and thus a negative pressure is formed in the first air cylinder 1064. Due to the transmission of the air tube 107, a negative pressure is also formed in the second air cylinder 1082. The negative pressure contracts the second piston 1083. One end of the second piston 1083 is fixedly connected with a locking pin 1085, and the locking pin 1085 also displaces towards the second air cylinder 1082, thereby releasing the lock of the docking head reinforcement device 2. When the steel ball 3014 rolls towards the other end of the circular tube 3011, similarly, this process is beneficial to improving the connection quality and reliability of the low-voltage wire harness joints.

[0043] Refer to Figure 9, the wire harness assembly 4 includes a low-voltage wire harness 401, both ends of the low-voltage wire harness 401 are electrically connected to connector housings 402, positioning blocks 403 are fixedly connected to the tops of the two connector housings 402, trapezoidal grooves 404 are provided on the fronts of the two positioning blocks 403, connection heads 405 are electrically connected to the inner walls on the backs of the two connector housings 402, and three electrode rods 406 are electrically connected to the inner walls on the backs of the two connection heads 405.

[0044] In this embodiment, it should be specifically noted that the three electrode rods 406 at both ends of the low-voltage wire harness 401 are arranged in a triangle.

[0045] The working principle of the present invention: Utilize the thrust released instantaneously by the first spring 103 to push the joint reinforcement device 2 towards the wire harness joint, and then reduce the friction between the sliding component and the wire harness through the balls 2013, so that the joint reinforcement device 2 can reach the wire harness joint. In addition, a magnet block 204 is provided on the joint reinforcement device. When the sliding component 201 contacts the wire harness joint, since the interface connecting the wire harness joint is mainly made of copper and its alloys, it will be adsorbed by the magnet block 204, thereby playing a role in strengthening the connection between the wire harness joint and the interface, thus avoiding the problem that the low-voltage line joint becomes loose and has poor contact due to the vehicle collision or other severe vibrations, and further causing a short-circuit problem, which is beneficial to improving the quality and reliability of the low-voltage wire harness, and also improving the efficiency and safety of the automotive electronic system.

[0046] When the environment where the trigger tube assembly 301 is located undergoes severe shaking, the steel ball 3014 rolls to both ends of the circular tube 3011 and impacts the impact rod 3013 to displace it. When the vehicle body undergoes severe shaking, the steel ball 3014 in the circular tube 3011 will roll back and forth along the inner wall of the circular tube 3011. When the steel ball rolls to one end of the circular tube 3011, the steel ball 3014 itself has a certain kinetic energy. When the steel ball 3014 impacts the impact rod 3013, the kinetic energy of the steel ball 3014 is transferred to the impact rod 3013, causing the impact rod 3013 to displace. One end of the impact rod 3013 is connected to a strip plate 303, and a square hole 304 is provided at one end of the strip plate 303. The protruding part of the tenon and mortise block 1061 of the piston assembly 106 is stuck at the edge of the square hole 304 so that it will not move forward under the action of the second spring 105. When the impact rod 3013 displaces, the strip plate 303 displaces in the same direction, and then the tenon and mortise block 1061 is located in the square hole 304, and the strip plate 303 cannot hold the tenon and mortise block 1061. Under the force of the second spring 105, the piston assembly 106 moves forward, and then a negative pressure is formed in the first air cylinder 1064. Due to the transmission of the air pipe 107, a negative pressure is also formed in the second air cylinder 1082. The negative pressure contracts the second piston 1083. One end of the second piston 1083 is fixedly connected to a locking pin 1085, and the locking pin 1085 also displaces towards the second air cylinder 1082, thereby releasing the lock of the docking head reinforcement device 2. When the steel ball 3014 rolls towards the other end of the circular tube 3011, similarly, this process is beneficial to improving the joint connection quality and reliability of the low-voltage wire harness.
