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

[0015] 1. The present invention is provided with a joint reinforcement device, which utilizes the instantaneous thrust released by the spring to push the joint reinforcement device toward the wiring harness joint, and then reduces the friction between the sliding component and the wiring harness through the ball bearing, so that the joint reinforcement device is sufficient to reach the wiring harness joint. In addition, a magnet is provided on the joint reinforcement device. When the joint reinforcement device contacts the wiring harness joint, since the interface connecting the wiring harness joint is mainly made of copper and its alloy material, it will be attracted by the magnet, thereby playing a role in reinforcing the connection between the wiring harness joint and the interface, thereby avoiding the low-voltage line joint from loosening and poor contact due to vehicle collision or other severe vibrations, thereby causing the occurrence of a short circuit problem, which is beneficial to improving the quality and reliability of the low-voltage wiring harness, and also improving the efficiency and safety of the automotive electronic system.

[0016] 2. The present invention is provided with a vibration trigger device. When the vehicle body shakes violently, the steel ball in the round tube rolls back and forth along the inner wall of the round tube. When the steel ball rolls to one end of the round tube, the steel ball itself has a certain kinetic energy. When the steel ball hits the short rod, the kinetic energy of the steel ball is transmitted to the short rod, causing the short rod to move. One end of the short rod is connected to a strip plate. One end of the strip plate is provided with a square hole. The convex part of the mortise and tenon block of the piston assembly is stuck on the edge of the square hole so that it will not move forward under the action of the spring. When the short rod is displaced, the strip plate moves in the same direction. The mortise and tenon block is displaced in the same direction, so that the mortise and tenon block is located in the square hole, and the strip plate cannot clamp the mortise and tenon 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 propagation of the air pipe, a negative pressure is also formed in the second air cylinder. The negative pressure contracts the second piston. A locking pin is fixedly connected to one end of the second piston, and the locking pin also moves toward the second air cylinder, thereby contacting the locking of the joint reinforcement device. When the steel ball rolls to the other end of the round tube, similarly, this process is beneficial to improving the connection quality and reliability of the joints of the low-voltage wiring harness.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples.

All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0028] Reference Figure 1 The present invention provides a low-voltage communication wiring harness for an automotive electronic system, comprising a fixing locking device 1, wherein a joint reinforcing device 2 is provided inside the fixing locking device 1, a wiring harness assembly 4 is movably sleeved on the inner side of the joint reinforcing device 2, and a vibration triggering device 3 is fixedly connected to the top of the fixing locking device 1.

[0029] What needs to be specifically explained in this embodiment is that two joint reinforcement devices 2 are provided in the inner cavity of the fixing locking device 1, and the joint reinforcement device 2 and the vibration trigger device 3 are directly temporarily connected through the mortise and tenon structure.

The vibration trigger device 3 is conducive to improving the quality and reliability of the joint connection of the low-voltage wiring harness. The specific structure and working principle of the above components will be described in detail later.

[0031] What needs to be specifically explained in this embodiment is that the two first springs 103 located on the front and back sides of the partition 102 are located on both sides of the circular hole of the partition 102 .

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

[0033] What needs to be specifically explained in this embodiment is that the cross block 1063 is located outside the first air cylinder 1064 . In actual use, the cross block 1063 will squeeze the second spring 105 , while the first air cylinder 1064 is located inside the second spring 105 .

[0034] Reference Figure 4 The locking assembly 108 includes a protective shell 1081, a second gas cylinder 1082 is fixedly sleeved on one side of the protective shell 1081, a side pipe at one end of the second gas cylinder 1082 is connected to the air pipe 107, a second piston 1083 is movably sleeved on the inner side of the second gas cylinder 1082, a third spring 1084 is fixedly connected to the inner wall of one side of the protective shell 1081, the second piston 1083 is located inside the third spring 1084, and a locking pin 1085 is fixedly connected to one end of the second piston 1083.

[0035] Reference Figure 5 The joint reinforcement device 2 includes a sliding component 201, both sides of the sliding component 201 are fixedly connected with connecting blocks 202, the front sides of the two connecting blocks 202 are fixedly connected with connecting rods 203, and one end of the two connecting rods 203 is fixedly connected with a magnet block 204.

[0036] It should be specifically explained in this embodiment that the connecting block 202 squeezes the first spring 103 and stabilizes the state through the locking pin 1085 .

[0037] Reference Figure 6 The sliding assembly 201 includes a harness ring 2011, an annular groove is provided on the inner side of the harness ring 2011, and five fixed rod frames 2012 are fixedly connected to the inner side of the harness ring 2011. The tops of the five fixed rod frames 2012 are all rotatably sleeved with balls 2013.

[0038] What needs to be specifically explained in this embodiment is that the annular space formed by the five balls 2013 is used to place the wiring harness. When the sliding component 201 moves, the balls 2013 roll directly on the outer surface of the wiring harness, making the movement of the sliding component 201 smoother. The first spring 103 is used to release the instantaneous thrust to push the joint reinforcement device 2 toward the wiring harness connector, and then the friction between the sliding component and the wiring harness is reduced by the balls 2013, so that the joint reinforcement device 2 is sufficient to reach the wiring harness connector. In addition, a magnet block 204 is provided in the joint reinforcement device. When the sliding component 201 contacts the wiring harness connector, since the interface connecting the wiring harness connector is mainly made of copper and its alloy material, it will be absorbed by the magnet block 204, thereby playing a role in reinforcing the connection between the wiring harness connector and the interface, thereby avoiding the low-voltage line connector from loosening and poor contact due to a collision or other severe vibration of the vehicle, thereby causing a short circuit problem, which is beneficial to improving the quality and reliability of the low-voltage wiring harness, and also improving the efficiency and safety of the automotive electronic system.

[0039] Reference Figure 7The vibration trigger device 3 includes a trigger tube assembly 301, both ends of the trigger tube assembly 301 are fixedly connected with connecting strips 302, one end of the two connecting strips 302 are fixedly connected with strip plates 303, one end of the two strip plates 303 are provided with square holes 304, the inner sides of the two square holes 304 are connected with piston assemblies 106 by mortise and tenon, and the bottom of the trigger tube assembly 301 is fixedly connected to the top of the surrounding shell 101.

[0040] In this embodiment, it is necessary to specifically explain that the two connecting strips 302 are respectively connected to the front and rear of the trigger tube assembly 301. Figure 7 As displayed.

[0041] Reference Figure 8 The trigger tube assembly 301 includes a round tube 3011, both ends of the round tube 3011 are fixedly connected with round pieces 3012, the inner sides of the two round pieces 3012 are movably sleeved with impact rods 3013, and a steel ball 3014 is placed in the inner cavity of the round tube 3011.

[0042] In the present embodiment, it is necessary to specifically explain that when the environment in which the trigger tube assembly 301 is located shakes violently, the steel ball 3014 rolls to both ends of the circular tube 3011 and hits the impact rod 3013 to displace it. When the vehicle body shakes violently, the steel ball 3014 in the circular tube 3011 rolls 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 hits 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 be displaced. One end of the impact rod 3013 is connected to a strip plate 303, and one end of the strip plate 303 is provided with a square hole 304. The raised portion of the mortise and tenon block 1061 of the piston assembly 106 is stuck on the edge of the square hole 304 so that it will not be in the second The strip plate 303 is displaced in the same direction as the spring 105, so that the mortise and tenon block 1061 is located in the square hole 304, and the strip plate 303 cannot jam the mortise and tenon block 1061. Under the force of the second spring 105, the piston assembly 106 moves forward, thereby forming a negative pressure in the first air cylinder 1064. Due to the propagation of the air pipe 107, a negative pressure is also formed in the second air cylinder 1082, and 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 is also displaced toward the second air cylinder 1082, thereby contacting the locking of the joint reinforcement device 2. When the steel ball 3014 rolls to the other end of the circular tube 3011, similarly, this process is conducive to improving the connection quality and reliability of the joints of the low-voltage wiring harness.

[0043] Reference Fig. 9The wiring harness assembly 4 includes a low-voltage wiring harness 401, both ends of which are electrically connected to a connector shell 402, the tops of the two connector shells 402 are fixedly connected to a positioning block 403, the fronts of the two positioning blocks 403 are provided with a trapezoidal groove 404, the inner walls on the backs of the two connector shells 402 are electrically connected to a connector 405, and the inner walls on the backs of the two connectors 405 are electrically connected to three electrode rods 406.

[0044] It should be specifically explained in this embodiment 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 is as follows: the first spring 103 is used to release the instantaneous thrust to push the joint reinforcement device 2 toward the wiring harness joint, and then the friction between the sliding component and the wiring harness is reduced by the ball 2013, so that the joint reinforcement device 2 is sufficient to reach the wiring harness joint. In addition, a magnet block 204 is provided in the joint reinforcement device. When the sliding component 201 contacts the wiring harness joint, since the interface connecting the wiring harness joint is mainly made of copper and its alloy material, it will be adsorbed by the magnet block 204, thereby playing a role in reinforcing the connection between the wiring harness joint and the interface, thereby avoiding the low-voltage line joint from loosening and poor contact due to a collision or other severe vibration of the vehicle, thereby causing a short circuit problem, which is beneficial to improving the quality and reliability of the low-voltage wiring harness, and also improving the efficiency and safety of the automotive electronic system.

[0046] When the environment in which the trigger tube assembly 301 is located shakes violently, the steel ball 3014 rolls to the two ends of the circular tube 3011 and hits the impact rod 3013 to displace it. When the vehicle body shakes violently, 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 hits 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 be displaced. One end of the impact rod 3013 is connected to a strip plate 303, and one end of the strip plate 303 is provided with a square hole 304. The raised part of the mortise and tenon block 1061 of the piston assembly 106 is stuck on the edge of the square hole 304 so that it will not be affected by the action of the second spring 105. The strip plate 303 is displaced in the same direction when the impact rod 3013 is displaced, so that the mortise and tenon block 1061 is located in the square hole 304, and the strip plate 303 cannot jam the mortise and tenon block 1061. Under the force of the second spring 105, the piston assembly 106 moves forward, thereby forming a negative pressure in the first air cylinder 1064. Due to the propagation of the air pipe 107, a negative pressure is also formed in the second air cylinder 1082, and 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 is also displaced toward the second air cylinder 1082, thereby contacting the locking of the joint reinforcement device 2. When the steel ball 3014 rolls to the other end of the circular tube 3011, similarly, this process is beneficial to improving the connection quality and reliability of the joints of the low-voltage wiring harness.
