Description

Technical Field

[0001] This invention relates to the field of braking system electrical connection technology, and in particular to a braking system wiring harness that is easy to install and remove. Background Technology

[0002] The braking system wiring harness is the core conductive and signal transmission carrier of the vehicle's electronic braking control system. It is composed of multiple flexible insulated wires, protective sheaths, and connectors. It is mainly arranged in the corresponding areas of the braking mechanism, such as the chassis, wheel wells, and engine compartment. It is responsible for transmitting ABS wheel speed signals, transmitting braking electronic control commands, and connecting the circuits of braking-related electrical components. During vehicle operation, dynamic conditions such as suspension bounce, wheel steering sway, and chassis vibration all require the flexible wiring harness to adapt to mechanical movements and ensure the real-time stable operation of the braking system. It is an indispensable connection component for the overall vehicle braking safety control and is directly related to the vehicle's braking response accuracy and driving safety stability.

[0003] Current automotive braking systems generally adopt a split, scattered wiring structure. Based on the installation location of each electrical component of the vehicle's braking system, multiple independent branch harnesses are laid out separately to match the connection requirements of different components such as wheel speed sensors, brake pedal switches, brake pressure sensors, and ESP electronic control modules. The overall assembly method adopts segmented wiring and single-point clip fixing. The wiring harness is organized and positioned by conventional insulating tape and simple fixing brackets. This is currently the mainstream wiring method for vehicle braking electrical connections, which can basically meet the usage requirements of braking system circuit conduction and signal transmission.

[0004] The existing scattered brake wiring harness layout has significant drawbacks in complex vehicle driving conditions and maintenance / disassembly scenarios. Multiple separate branch harnesses are difficult to arrange neatly in the confined and densely packed component installation space of the chassis. This makes vehicle assembly and after-sales maintenance disassembly and disassembly operations cumbersome and inefficient. At the same time, the continuous chassis vibration, suspension extension and contraction, and wheel steering sway during vehicle operation cause the unorganized wiring harness to repeatedly twist, stick together, and sag. This easily leads to the wiring harnesses getting tangled and getting caught on surrounding mechanical components. Long-term dynamic stress can cause wear on the wiring harness insulation layer, fatigue fracture of the internal copper core, and loosening and falling off of the connectors. This can not only cause brake signal interruption and poor circuit contact, but also seriously affect the working stability of the braking system and significantly increase vehicle fault repair costs and driving safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a braking system wiring harness that is easy to install and remove, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a brake system wiring harness that is easy to assemble and disassemble, comprising a detachable base ring, wherein a detachable positioning mechanism is fixedly installed on the top of the detachable base ring in a ring with equal spacing, the detachable positioning mechanism clamps and winds a wiring harness body, and a plug is fixedly connected to the inner end of the wiring harness body. The plug and the detachable positioning mechanism are connected by plugging in and electrically, and the detachable positioning mechanism is electrically connected to the detachable base ring through a conductive slip ring.

A rotating seat is rotatably connected to the bottom inner side of the circular shell. A torsion spring is fixedly connected to the top of the rotating seat. A turntable is fixedly connected to the top of the torsion spring. The turntable is rotatably connected to the top of the inner side of the circular shell. The winding module is fixedly connected to the top of the turntable.

[0012] Furthermore, the positioning module includes an outer shell, which is fixedly connected to the outer center of the arc-shaped block. The inner side of the outer shell is connected to the inner side of the circular shell. A lead screw is rotatably connected inside the outer shell, and a movable block is threadedly connected to the outer surface of the lead screw. The movable block slides inside the outer shell. A reserved groove is provided on one side of the outer shell. An adjusting knob handle is fixedly connected to the outer end of the lead screw through the outer shell. A limiting external rod is fixedly connected to one side of the movable block. A limiting pin is fixedly connected to the outer end of the limiting external rod. The end of the limiting pin passes through the limiting hole on the assembly groove 12 and is inserted into the limiting hole of the assembly block. If it is necessary to prevent the lead screw from accidentally slipping due to vibration, a positioning screw can be threaded onto the adjusting knob handle. After turning the adjusting knob handle, the adjusting knob can be further positioned by the screw. At the same time, the screw on the adjusting knob handle can be a hand-tightening screw for easy subsequent adjustment.

[0013] Furthermore, the outer side of the rotating seat is provided with locking holes arranged in a ring at equal intervals, and the lower inner side of the movable block is fixedly connected with a locking pin. The end of the locking pin is inserted into a locking hole for positioning the rotating seat.

[0014] Furthermore, the winding module includes a winding wheel, which is fixedly connected to the top of the turntable. A top housing is fixedly connected to the top of the winding wheel. A reserved positioning groove is provided at the bottom of the winding wheel. A power connection socket is fixedly connected to one side of the top of the turntable. A conductive slip ring is provided on the turntable. The power connection socket is electrically connected to the power connection socket at the end of the wiring conduit through the conductive slip ring and the wire. The end of the wire harness body is electrically connected to the power connection socket through a plug. A limiting component is provided on the inner side of the top housing. The limiting end of the limiting component extends into the reserved positioning groove. The wire harness body is held in place by the limiting component in the reserved positioning groove.

The bottom end of the push rod passes through the winding wheel and extends into the reserved positioning groove, where a clamping plate is fixedly connected. Anti-slip conical teeth are evenly spaced on the bottom of the clamping plate and the bottom of the reserved positioning groove. After the clamping plate is plugged into the wire harness body and the power connector socket to form an electrical connection, it locks and limits the wire harness body. A quick-adjusting shaft is fixedly connected to the top of the push plate, and a quick-adjusting pull ring is fixedly mounted on the top end of the quick-adjusting shaft through the top housing.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, the technical solution utilizes a modular base ring paired with a positioning module, a winding module paired with an elastic energy storage buffer module and a limiting component, along with a conductive slip ring. This allows for the integration and centralized arrangement of multiple brake harnesses during use, while also organizing excess wires. This achieves a unified approach to assembly layout and vehicle operating conditions. The modular base ring and positioning module work together to gather various brake lines that were originally scattered. They can be flexibly assembled according to on-site wiring conditions. During assembly, it is not necessary to fix individual wire harnesses, simplifying the vehicle assembly process. In subsequent maintenance, the entire harness can be disassembled as a whole, reducing the time spent on disassembling wires step by step. The gathered wires are confined within the base ring's layout area, preventing them from extending and touching surrounding mechanical components of the chassis. The winding module and limiting components can uniformly store excess wiring harnesses, preventing them from becoming disorderly tangled during vehicle vibrations. The elastic energy storage buffer module can release a small section of wire when the wiring harness is accidentally pulled, working in conjunction with the winding wheel. After the external force disappears, the structure automatically retracts the released wiring harness. The limiting components clamp the wiring harness ends, reducing the possibility of plugs coming loose. The conductive slip ring follows the rotation of the winding structure to continuously maintain circuit continuity. Multiple structures work together to simultaneously complete wiring harness assembly and storage, wiring constraints, and dynamic buffering. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 8 In this embodiment of the invention, a brake system wiring harness that is easy to assemble and disassemble includes a detachable base ring 1. A detachable positioning mechanism 2 is fixedly installed on the top of the detachable base ring 1 in a ring-shaped arrangement with equal intervals. A wiring harness body 3 is clamped and wound inside the detachable positioning mechanism 2. A plug 4 is fixedly connected to the inner end of the wiring harness body 3. The plug 4 and the detachable positioning mechanism 2 are connected by plugging and electrical connection. The detachable positioning mechanism 2 is electrically connected to the detachable base ring 1 through a conductive slip ring. The detachable positioning mechanism 2 for wire harnesses includes an elastic energy storage buffer module 21, a winding module 22, and a positioning module 23. The elastic energy storage buffer module 21 is arranged in a ring at equal intervals and fixedly installed on the top of the detachable base ring 1. The winding module 22 is fixedly connected to the top of the elastic energy storage buffer module 21. The positioning module 23 is arranged in a ring at equal intervals and fixedly installed on the outside of the detachable base ring 1. The detachable base ring 1 is assembled and positioned by the positioning module 23. During the application of this device, by setting up the detachable base ring 1 in conjunction with the detachable positioning mechanism 2, the detachable base ring 1 is first assembled and fixed by the positioning module 23. After the base ring is assembled, the wire harness body 3 is placed inside the detachable positioning mechanism 2. The clamping operation of the wire harness body 3 is completed by relying on the mechanism structure. The winding operation is carried out simultaneously inside the detachable positioning mechanism 2. The plug 4 at the end of the wire harness body 3 is inserted into the detachable positioning mechanism 2. Electrical connection is established, and the circuit connection path between the detachable positioning mechanism 2 and the assembleable base ring 1 is built by relying on the conductive slip ring. The elastic energy storage buffer module 21, the winding module 22, and the positioning module 23, which are separated from the detachable positioning mechanism 2, undertake different tasks. The winding module 22 controls the storage margin of the wire harness body 3. The elastic energy storage buffer module 21 works with the winding module 22 to buffer the external force pulling on the wire harness during use. Through this combination arrangement, multiple wire harnesses can be centrally stored and controlled, thereby achieving the effect of gathering and dispersing the wires. The operation steps of fixing a single wire harness are eliminated. When the wire harness needs to be disassembled, the clamping structure of the detachable positioning mechanism 2 can be released directly to take out the wire harness body 3, thereby reducing the disassembly and assembly operation steps. The conductive slip ring can follow the movement of the winding module 22 to continuously maintain the circuit conduction. The circuit will not be disconnected when the winding module 22 adjusts the length of the wire harness.

[0021] Please see Figures 1-5The modular base ring 1 includes several arc-shaped blocks 11. One end of each arc-shaped block 11 has an assembly groove 12, and the other end of each arc-shaped block 11 is fixedly fitted with an assembly block 13. The assembly block 13 is inserted into the inner side of the assembly groove 12. A positioning module 23 is fixedly connected to the outer side of the arc-shaped block 11, and a winding module 22 is fixedly connected to the top of the arc-shaped block 11. During application, the modular base ring 1 is formed by assembling arc-shaped blocks 11 with assembly grooves 12 and assembly blocks 13. This allows the assembly blocks 13 at the ends of individual arc-shaped blocks 11 to be inserted into the assembly grooves 12 of adjacent arc-shaped blocks 11, thereby enabling the splicing and combination of multiple sets of arc-shaped blocks 11. This allows for flexible assembly of the modular base ring 1. In the assembly process, the positioning module 23 is assembled on the outside of the arc-shaped block 11, which can work with the splicing structure to complete the positioning and fixing work after the overall assembly. The winding module 22 is assembled on the top of the arc-shaped block 11, which can match the spliced ​​base structure to arrange the wire harness storage structure. The segmented splicing structure can change the limitation of the integral base that cannot be disassembled. It can complete the assembly operation piece by piece in a small installation space, reducing the difficulty of the overall assembly operation. During the disassembly process, the arc-shaped blocks 11 can be disassembled one by one without the need for overall disassembly, which can simplify the disassembly and assembly process. The winding module 22, which is independently arranged for the arc-shaped block 11, can also be used to store different wire harnesses in different areas, making the wire harness arrangement more neat and orderly.

[0022] Please see Figures 1-5 Limiting holes 14 are provided on the outer side of the arc-shaped block 11 and the outer side of the assembly groove 12. The assembly blocks 13 of adjacent arc-shaped blocks 11 are inserted and fitted into the assembly groove 12. Several arc-shaped blocks 11 are interlocked with the assembly blocks 13 through the assembly groove 12 to form an assembly base ring. The limiting end of the positioning module 23 extends through the limiting hole 14 of the assembly groove 12 and is inserted into the limiting hole 14 of the assembly block 13. During the application of this device, by setting the structure of arc-shaped blocks 11 with assembly groove 12, assembly blocks 13 and limiting holes 14, it is possible to install the assembly blocks 13 of adjacent arc-shaped blocks 11 into the assembly groove 12 during use, so that multiple sets of arc-shaped blocks 11 can be interlocked and spliced ​​to form a complete assembly base ring. The arc-shaped blocks 11 and the assembly groove 12 The limiting holes 14 on the outer side can be aligned with each other after the structure is assembled. The limiting end of the positioning module 23 passes through the aligned limiting holes 14 and is inserted into the limiting holes 14 of the assembly block 13. This can lock and limit the assembled arc block 11 combination structure, eliminate the gap caused by the fitting of the assembly groove 12 and the assembly block 13, and prevent structural misalignment and loosening of the assembly base ring during use. The overall combination of fitting and perforation limiting fixation can improve the tightness of the fitting of the arc block 11 after assembly. When disassembling, it is only necessary to release the insertion state of the limiting end of the positioning module 23 to separate each group of arc blocks 11, which can simplify the disassembly and assembly process of the assembly base ring.

[0023] Please see Figures 3-5A fixing arc plate 15 is fixedly installed on the outer side of the arc-shaped block 11. Mounting holes 16 are provided at both ends of the outer side of the fixing arc plate 15. The mounting holes 16 are countersunk holes. The fixing arc plates 15 are combined to form a ring-shaped fixing structure. The top view of the assembly groove 12 and the assembly block 13 is convex. During application, by setting the arc-shaped block 11 with the fixing arc plate 15, and cooperating with the countersunk mounting holes 16 and the convex assembly groove 12 and assembly block 13, the convex assembly groove 12 and assembly block 13 interlock and connect during use. The arc-shaped block 11, constrained by its external contour, exhibits lateral displacement after assembly. Multiple fixed arc plates 15 are joined together with the arc blocks 11 to form a ring-shaped fixing structure. Workers use the countersunk mounting holes 16 at both ends of the fixed arc plates 15 to complete the locking operation of the device and the assembly carrier. The countersunk design can store the fastening accessories inside the holes to prevent the accessories from being exposed and bumping into the surrounding components. The arc block splicing position is pre-defined by the shape of the clamp, and the overall fastening is completed by relying on the ring-shaped fixed arc plates 15. The two operations of splicing and fixing the whole machine can be completed separately. When disassembling later, the fastening accessories inside the mounting holes 16 can be loosened to release the external restraint, thereby shortening the operation steps required to disassemble the entire base ring.

[0024] Please see Figures 3-5 A wiring conduit 17 is fixedly connected to the inner side of the arc-shaped block 11. An electrical socket 18 is installed inside the wiring conduit 17. One path of the electrical socket 18 connects to the braking system via a wire and a connecting connector for the braking system. The other path connects to the winding module 22 via a wire and a conductive slip ring. By configuring the wiring conduit 17 inside the arc-shaped block 11 and the electrical socket 18 inside the wiring conduit 17, the electrical socket 18 branches into two independent circuits during use. One circuit connects to the braking system via a wire and a connecting connector for the braking system, while the other circuit... By using wires and conductive slip rings to connect the receiving module 22, the branched wiring can be connected to two power-consuming parts separately, eliminating the need for additional intermediate wiring components and reducing the messy arrangement of unnecessary external wiring. The conductive slip rings connected in the middle of the circuit can adapt to the rotational movement of the receiving module 22. During the rotational changes of the winding and unwinding of the winding module 22, the circuits on both sides can remain connected. When inspecting the related structure of the receiving module 22 in the later stage, the corresponding branch can be disconnected separately by relying on the two independent wirings without interrupting the overall power supply of the braking system.

[0025] Please see Figures 3-7The elastic energy storage buffer module 21 includes a circular shell 211, which is fixedly connected to the center of the arc-shaped block 11. A rotating seat 212 is rotatably connected to the bottom inner side of the circular shell 211. A torsion spring 213 is fixedly connected to the top of the rotating seat 212. A turntable 214 is fixedly connected to the top of the torsion spring 213. The turntable 214 is rotatably connected to the top inner side of the circular shell 211. A winding module 22 is fixedly connected to the top of the turntable 214. During the application of this device, the circular shell 211, rotating seat 212, torsion spring 213, and turntable 214 constitute the elastic energy storage buffer module 21. This allows the circular shell 211 to provide a regular installation space for the internal rotating structure during use. The rotating seat 212 is rotated and assembled based on the bottom of the circular shell 211. The torsion spring 213 is connected to the rotating seat. Between 212 and turntable 214, turntable 214 can rotate freely inside the circular housing 211. The winding module 22 mounted on the top of turntable 214 can rotate synchronously with turntable 214. When the wire harness body 3 is pulled by an external force, it will drive the winding module 22 to rotate, thereby driving turntable 214 to torsion spring 213. The deformation of torsion spring 213 can adapt to the stretching action of the wire harness, thereby releasing the corresponding length of wire harness to offset the external pulling force. After the external force is completely eliminated, torsion spring 213 can automatically rebound and reset, driving turntable 214 and winding module 22 to rotate in the opposite direction, which can re-gather the outward wire harness body 3. The overall integrated structure can limit the range of motion of internal components, which can prevent the rotating parts from shifting and shaking, and continuously adapt to the daily winding adjustment and dynamic buffer protection needs of the wire harness.

[0026] Please see Figures 3-7The positioning module 23 includes an outer shell 231, which is fixedly connected to the outer center of the arc-shaped block 11. The inner side of the outer shell 231 is connected to the inner side of the circular shell 211. A lead screw 232 is rotatably connected inside the outer shell 231. A movable block 233 is threadedly connected to the outer surface of the lead screw 232 and slides inside the outer shell 231. A reserved groove 234 is provided on one side of the outer shell 231. An adjustment mechanism is fixedly connected to the outer end of the lead screw 232 through the outer shell 231. A limiting external rod 236 is fixedly connected to one side of the knob handle 235 and the movable block 233. A limiting pin 237 is fixedly connected to the outer end of the limiting external rod 236. The end of the limiting pin 237 passes through the limiting hole 14 on the assembly slot 12 and is inserted into the limiting hole 14 of the assembly block 13. During the application of this device, it forms a positioning module 23 by setting up the outer shell 231, the lead screw 232, the movable block 233, the adjusting knob handle 235, the limiting external rod 236, and the limiting pin 237. This design allows the outer shell 231 to integrate with the internal space of the circular shell 211 during use, resulting in a more regular internal structure layout. Rotating the adjustment knob 235 can drive the lead screw 232 to rotate. The lead screw 232 can drive the movable block 233 to slide smoothly inside the outer shell 231 via threaded transmission. While the movable block 233 slides, it can drive the limiting external rod 236 to move along the reserved groove 234, thereby controlling the limiting pin 237 to complete the telescopic displacement. After the limiting pin 237 extends, it can pass through the limiting hole 14 of the assembly groove 12 and insert into the limiting hole 14 of the assembly block 13, which can lock and fix the assembled base ring structure. After the limiting pin 237 retracts, it can directly release the splicing limit of the base ring. The operator can complete the locking and unlocking operation of the structure by simply rotating the adjustment knob 235, which can save the use of various auxiliary disassembly and assembly tools, greatly simplify the operation steps of assembling and disassembling the base ring, and flexibly control the combination and separation state of the base ring structure.

[0027] Please see Figures 2-6The rotating base 212 has equally spaced, ring-shaped locking holes 238 on its outer side. A locking pin 239 is fixedly connected to the lower inner end of the movable block 233. The end of the locking pin 239 is inserted into a locking hole 238 to position the rotating base 212. During application, the equally spaced, ring-shaped locking holes 238 on the outer side of the rotating base 212 and the locking pin 239 mounted on the lower end of the movable block 233 ensure that during use, the movable block 233 of the positioning module 23 slides, causing the locking pin 239 to move synchronously, allowing the end of the locking pin 239 to engage with the corresponding locking hole 238 on the rotating base 212, thereby locking the rotating base 212. The rotation position of 12 can restrict the rotational freedom of the rotating seat 212 and the turntable 214, thereby fixing the wire harness winding length of the winding module 22. The equally spaced locking holes 238 can match different rotation angles and can adapt to the positioning requirements of various wire harness winding allowances. When the wire harness length needs to be readjusted, the positioning module 23 can be adjusted to drive the movable block 233 to move, so that the locking pin 239 disengages from the inside of the locking hole 238, thereby releasing the locking state of the rotating seat 212, allowing the winding module 22 to rotate again to complete the winding and unwinding adjustment of the wire harness. It can flexibly switch between the fixed state and the adjustment state of the wire harness to adapt to the wire harness layout requirements in different scenarios.

[0028] Please see Figures 5-8The take-up module 22 includes a take-up roller 221, which is fixedly connected to the top of the turntable 214. A top housing 222 is fixedly connected to the top of the take-up roller 221. A reserved positioning groove 223 is provided at the bottom of the take-up roller 221. A power connection socket 224 is fixedly connected to one side of the top of the turntable 214. A conductive slip ring is provided on the turntable 214. The power connection socket 224 is electrically connected to the power connection socket 18 at the end of the wiring conduit 17 through the conductive slip ring and the wire. The wire harness body The end of 3 is electrically connected via plug 4 and power connector 224. A limiting component 225 is provided on the inner side of the top housing 222. The limiting end of the limiting component 225 extends into the reserved positioning groove 223. The limiting component 225 holds the wire harness body 3 within the reserved positioning groove 223. The wire harness body 3 is wound onto the outer surface of the winding wheel 221. During application, this device utilizes the winding wheel 221, top housing 222, reserved positioning groove 223, and power connector 224. The conductive slip ring and the limiting component 225 form the winding module 22, so that during use, the auxiliary power socket 224 is connected to the power socket 18 at the wiring conduit 17 by means of the conductive slip ring and the wire. The wire harness body 3 is connected to the auxiliary power socket 224 by means of the end plug 4 to complete the circuit connection. After the end of the wire harness body 3 is placed in the reserved positioning groove 223, the end is clamped by the limiting component 225. The excess wire harness body 3 is wrapped around the outer surface of the winding wheel 221. The winding wheel 221 rotates synchronously with the turntable 214. The conductive slip ring can keep the circuit connected by following the rotation of the winding wheel 221 and will not cut the circuit path due to the winding operation. The limiting component 225 binds the end of the wire harness inside the reserved positioning groove 223, which can prevent the end from falling off the plugged position when the wire harness is wound up and down. When it is necessary to remove the wire harness body 3, the clamping constraint of the limiting component 225 can be released to pull out the wire without disassembling the entire plugged circuit, which can simplify the operation process of wire harness disassembly and assembly.

[0029] Please see Figures 5-8The limiting assembly 225 includes a limiting spring 2251, which is fixedly installed inside the top housing 222. A push plate 2252 is fixedly connected to the bottom of the limiting spring 2251, and a push rod 2253 is fixedly connected to the bottom of the push plate 2252. The bottom end of the push rod 2253 passes through the winding wheel 221 and extends into the reserved positioning groove 223, where a clamping plate 2254 is fixedly connected. Anti-slip conical teeth 2255 are evenly spaced on the bottom of the clamping plate 2254 and the bottom of the reserved positioning groove 223. After the wire harness body 3 and the power connector 224 are plugged in to form an electrical connection, the wire harness body 3 is locked and limited. A quick-adjusting shaft 2256 is fixedly connected to the top of the push plate 2252. The top of the quick-adjusting shaft 2256 passes through the top housing 222 and is fixedly fitted with a quick-adjusting pull ring 2257. During the application of this device, the limiting assembly 225, composed of a limiting spring 2251, push plate 2252, push rod 2253, clamping plate 2254, quick-adjusting shaft 2256, and quick-adjusting pull ring 2257, ensures... When in use, pulling the quick-adjusting ring 2257 causes the quick-adjusting shaft 2256 to move upward, simultaneously pulling the push plate 2252 to compress the limit spring 2251. The push rod 2253 follows the push plate 2252 to raise the clamping plate 2254, thereby opening the clamping space of the reserved positioning slot 223, making it convenient for the operator to put the end of the wire harness body 3 into the slot. After releasing the quick-adjusting ring 2257, the limit spring 2251 rebounds, causing the push plate 2252, push rod 2253, and clamping plate 2254 to return to their original position downward. The anti-slip conical teeth 2255 on the bottom surface of plate 2254 and the reserved positioning groove 223 work together to clamp the end of the wire harness. The anti-slip conical teeth 2255 can increase the biting effect of the contact surface and reduce the possibility of the end of the wire harness slipping out during the winding and unwinding process. When the wire harness needs to be disassembled later, the clamping constraint of the clamp plate 2254 can be released by pulling the quick adjustment ring 2257 again. There is no need to disassemble other connected structures. The wire harness can be quickly released from its fixed state, shortening the operation steps of wire harness disassembly and assembly and improving the overall convenience of its use.

[0030] The working principle of this invention is as follows: During application, the assembly and use of this device can first complete the overall base assembly operation. By embedding the matching assembly block 13 of the arc-shaped block 11 into the corresponding assembly slot 12, the convex structure of the assembly slot 12 and the assembly block 13 achieves fitting and docking. This allows multiple sets of arc-shaped blocks 11 to cooperate with each other to form a complete assemblable base ring 1. After the splicing operation is completed, the adjustment knob handle 235 of the positioning module 23 can be rotated, causing the lead screw 232 to rotate synchronously, thereby driving the movable block 233 to move smoothly inside the outer shell 231. The movable block 233 moves simultaneously with the... When the time is right, the limiting external rod 236 can slide along the inside of the reserved groove 234, so that the limiting pin 237 can pass through the limiting hole 14 corresponding to the assembly groove 12 and the assembly block 13, thereby locking and fixing the assembled base ring 1 as a whole. At the same time, the screw rod 232 structure can be locked by adjusting the hand-tightening positioning screw mounted on the knob handle 235, which can prevent the screw rod 232 from slipping and loosening due to the vibration generated by the vehicle operation. The fixing arc plate 15 mounted on the outside of each arc block 11 can cooperate with the mounting hole 16 of the countersunk structure to complete the docking and fixing of the whole device with the vehicle installation position, thereby completing the overall assembly of the basic structure of the device.

[0031] After the assembly and fixing of the modular base ring 1 is completed, the circuit connection operation can be carried out. The circuit of the vehicle braking system can be connected to the power socket 18 of the wiring pipe 17 inside the arc-shaped block 11. The power socket 18 can establish a circuit path with the power auxiliary socket 224 on the top of the turntable 214 through the matching wire and the conductive slip ring, so that the power and control signals of the braking system can be transmitted normally. The plug 4 at the end of the wire harness body 3 is inserted and installed in the power auxiliary socket 224, which can complete the electrical connection between the wire harness body 3 and the braking system, and conduct electricity. The slip ring can maintain the circuit connection during the rotation of the turntable 214, thereby achieving stable power supply during rotation. After the circuit connection is completed, the adjustment knob 235 of the positioning module 23 can be operated again to drive the lead screw 232 to drive the movable block 233 to move in the opposite direction. This causes the locking pin 239 at the bottom of the movable block 233 to disengage from the locking hole 238 on the outside of the rotating seat 212, thereby releasing the rotation limit between the rotating seat 212 and the turntable 214, allowing the winding module 22 to rotate freely.

[0032] After the circuit and limiting structure are debugged, the wire harness body 3 can be fixed and its length adjusted. By pulling the quick adjustment ring 2257 on the top of the top housing 222, the quick adjustment shaft 2256 can be moved axially, which in turn pulls the push plate 2252 to compress the limiting spring 2251, causing the clamping plate 2254 connected to the bottom of the push rod 2253 to move upward synchronously. This opens the reserved positioning groove 223 at the bottom of the take-up wheel 221, and the operator can place the wire harness body 3, which has been connected, into the reserved positioning groove 223. After releasing the quick adjustment ring 2257, the limiting spring 2251 returns to its original position, which can push the clamping plate 2254 down to fit the wire harness body 3. The clamping plate 2254 and the anti-slip bevel teeth 2255 arranged inside the reserved positioning groove 223 complete the clamping and fixing of the wire harness body 3. Afterwards, the turntable 214 and the rotating seat 212 can be manually rotated to drive the take-up wheel 221. 21 rotates synchronously, thereby winding and storing the excess length of the wire harness body 3 on the outer surface of the winding wheel 221. After winding, the positioning module 23 resets its limiting structure, allowing the locking pin 239 to re-engage into the locking hole 238 to lock the rotation structure. If the wire harness body 3 is subjected to external pulling force during vehicle operation, it will drive the winding wheel 221 and the turntable 214 to rotate, thereby torturing the torsion spring 213 to produce elastic deformation. During the deformation of the torsion spring 213, it can release part of the wire harness body 3 to offset the hard pulling force. When the external pulling force disappears, the torsion spring 213 rebounds and resets, which can drive the winding wheel 221 to rotate in the opposite direction, re-organize and wind the wire harness body 3, and continue to maintain the neat layout of the wire harness. When subsequent maintenance and disassembly are required, it is only necessary to release the limiting structure of the positioning module 23 and the limiting component 225 in sequence to complete the disassembly operation of the wire harness body 3 and the device as a whole.

[0033] This technical solution adopts a modular, assembleable base ring 1 structure, which can change the traditional layout of dispersed and independent wiring and single-point fixing of brake harnesses. It can complete the centralized positioning and layout of multiple harness bodies 3 according to the actual wiring requirements of the vehicle braking system, which can reduce the messy wiring harness layout in the confined space of the vehicle chassis, reduce the difficulty of vehicle assembly and subsequent maintenance. Through the cooperation of the winding wheel 221 and the limiting component 225, the excess harness bodies 3 after wiring can be uniformly collected and restrained, preventing the harnesses from tangling during vehicle driving vibration, and also preventing the harnesses from drooping and getting stuck with chassis mechanical components or road protrusions. To prevent dragging and snagging, the frequency of wear and tear on the outer sheath of the wire harness is reduced. The elastic energy storage buffer module 21 can buffer the external force through structural deformation when the wire harness is subjected to sudden tensile force, changing the working state of the wire harness under rigid force and reducing the damage problem caused by long-term stress on the copper wires inside the wire harness. The use of conductive slip rings can maintain the circuit path during the adjustment of the wire harness length by rotating the winding structure, avoiding the circuit disconnection problem caused by structural rotation. The multiple unlockable limit design of the overall structure can simplify the operation steps of wire harness disassembly and replacement, and reduce secondary damage to the wire harness body 3 during disassembly and assembly.
