[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] First embodiment

[0037] The current design of the wire management clip that fixes all wire harnesses together can ensure the neatness and orderliness of the wire harnesses. However, during actual maintenance, it is necessary to disassemble all the wire harnesses and then find the corresponding wire harness for maintenance or replacement, which is time-consuming and laborious and increases the complexity of the maintenance work. To facilitate the quick maintenance or replacement of the problematic wire harness, reduce the inconvenience during the maintenance process, and improve the maintenance efficiency, as Figure 1 - Figure 7 shown, this embodiment provides an electric vehicle wire harness management and positioning clip, which is composed of a housing 1, three equally spaced clamping components 2, and a driving component 3. In this embodiment, three groups of clamping components 2 are provided. In fact, four groups, five groups, etc. can also be set. The back of the housing 1 is usually fixed inside the electric vehicle by bonding or screws.

[0038] In order to quickly repair or replace one or more wire harnesses and reduce interference with other wire harnesses, the clamping component 2 is used to clamp and fix the electric vehicle wire harness to ensure that the wire harness is neat and firm. It includes two arc-shaped clamping rods 21, a transmission component 23 and a positioning component 24. The two arc-shaped clamping rods 21 are symmetrically arranged, and the bottom ends of the arc-shaped clamping rods 21 penetrate through the housing 1 and extend to its inner side. The design of the arc-shaped clamping rods 21 enables the wire harness to be clamped evenly and gently, avoiding problems such as excessive extrusion, bending or damage that may occur in the traditional wire harness clamping method. The transmission component 23 and the positioning component 24 are both arranged inside the housing 1. Magnetic blocks 22 connected by magnetic attraction are respectively fixed to the tops of the two arc-shaped clamping rods 21. After the two arc-shaped clamping rods 21 rotate a certain angle towards the middle to clamp the wire harness, the two magnetic blocks 22 are fixed to each other through magnetic attraction, improving the stability of the wire harness clamping.

[0039] The driving component 3 is used to drive the three groups of clamping components 2 to clamp three wire harnesses synchronously and lock them on the housing 1. It includes a strip-shaped rod 31, a rotating component 32 and a limiting component 33. The strip-shaped rod 31 is slidably arranged at the bottom inside the housing 1. The rotating component 32 is arranged on the strip-shaped rod 31 and is used to push it to move unidirectionally. The limiting component 33 is arranged inside the housing 1 to limit the moving position of the strip-shaped rod 31, and thus limit the rotation angle of the arc-shaped clamping rod 21, so that the two arc-shaped clamping rods 21 on each group of clamping components 2 can be rotated simultaneously, and the three wire harnesses can be disassembled at the same time, allowing maintenance personnel to repair or replace the problematic wire harness, reducing interference with other wire harnesses and reducing the inconvenience during the maintenance process.

[0040] In order to prevent the wire harness from becoming loose during the driving of the electric vehicle and affecting safety, when the transmission component 23 synchronously drives the two arc-shaped clamping rods 21 to rotate towards the middle to clamp the wire harness, and the arc-shaped clamping rods 21 are clamped in the housing 1 through the positioning component. The transmission component 23 includes two symmetrically arranged limiting frame bodies 231, L-shaped magnetic blocks 232 magnetically attracted and fixed to both ends of the limiting frame bodies 231 and fixed to the housing 1. The two limiting frame bodies 231 are inserted into the inner side of the housing 1, and both ends of the limiting frame bodies 231 are fixed to the L-shaped magnetic blocks 232 through magnetic attraction. At the bottom of the two arc-shaped clamping rods 21, limiting rotating shafts 233 are respectively fixed, and both ends of the limiting rotating shafts 233 respectively penetrate through the two limiting frame bodies 231 and are rotatably connected thereto. At one end of the two limiting rotating shafts 233, a driving gear 234 and a driven gear 235 that are meshed with each other are respectively fixed. The driving gear 234 and the driven gear 235 move in opposite directions at the same time. The tooth width of the driving gear 234 is greater than the tooth width of the driven gear 235. At the bottom of one side of the driving gear 234, a first rack 236 fixed to the strip-shaped rod 31 is meshed. When the first rack 236 moves, it drives the driving gear 234 and the driven gear 235 to rotate simultaneously, drives the two limiting rotating shafts 233 to rotate simultaneously, and the two limiting rotating shafts 233 respectively drive the two arc-shaped clamping rods 21 to rotate towards the middle. The two magnetic blocks 22 are fixed to each other through magnetic attraction to clamp the wire harness in this way.

[0041] Among them, in order to improve the stability of the wire harness fixation, the positioning component 24 includes limiting bearings 241 respectively arranged at both ends of the limiting rotating shaft 233, a threaded sleeve 242 rotatably arranged inside the limiting bearing 241, and limiting grooves opened on both inner side walls of the housing 1. And the two limiting bearings 241 respectively match the two opposite limiting grooves. Threaded shafts 243 fixed to both ends of the limiting rotating shaft 233 are respectively threadedly arranged inside the two threaded sleeves 242. On one side of the threaded sleeve 242, a telescopic rod 244 fixed to the limiting frame body 231 is arranged. The movable end of the telescopic rod 244 is fixed to one side of the threaded sleeve 242, and the fixed end of the telescopic rod 244 is fixed to the limiting frame body 231. When the limiting rotating shaft 233 rotates, it drives the threaded shaft 243 to rotate. The threaded shaft 243 drives the threaded sleeve 242 and the limiting bearing 241 to move, and the limiting bearing 241 enters the limiting groove, thereby restricting the longitudinal position of the arc-shaped clamping rod 21 and making the clamping of the wire harness by the two arc-shaped clamping rods 21 more stable.

[0042] Second Embodiment

[0043] In order to prevent wear during the wire harness clamping process and extend the service life of the wire harness, as Figure 1 - Figure 7As shown, the clamping member 2 of the first embodiment further includes a pressing member 25 respectively arranged on two arc-shaped clamping rods 21. Specifically, the pressing member 25 includes anti-slip soft pads 251 respectively arranged at both ends of the concave part of the arc-shaped clamping rod 21. A connecting shaft 252 is fixed on one side of the anti-slip soft pad 251. A return spring 253 is sleeved outside the connecting shaft 252. Both ends of the return spring 253 are fixedly connected with the anti-slip soft pad 251 and the arc-shaped clamping rod 21 respectively, and the connecting shaft 252 penetrates through the arc-shaped clamping rod 21 and is slidably connected with it.

[0044] When the two arc-shaped clamping rods 21 move towards the middle, the arc-shaped clamping rod 21 drives the anti-slip soft pad 251 to move through the connecting shaft 252. The four anti-slip soft pads 251 move towards the middle to clamp the wire harness, effectively reducing the direct pressure of the current rigid clamping rod on the wire harness, avoiding damage or wear to the outer layer of the wire harness. At the same time, the return spring 253 connects the anti-slip soft pad 251 and the arc-shaped clamping rod 21, which can effectively absorb a certain amount of vibration and reduce the impact on the wire harness.

[0045] The third embodiment

[0046] In order to push the strip-shaped rod 31 to move, three groups of clamping members 2 can be driven to operate simultaneously to improve the consistency of the positioning clamp. As Figure 1 - Figure 7 shown, the rotating member 32 of the first embodiment. Specifically, the rotating member 32 includes a transmission gear 321 arranged on the top of the strip-shaped rod 31, and a second rack 322 meshed with the bottom of the transmission gear 321 and fixed to the strip-shaped rod 31. A transmission cross shaft 323 is fixed at the center of the axis of the transmission gear 321. The transmission cross shaft 323 penetrates through one side of the housing 1 and is rotatably connected with it through a bearing. A spiral cap 324 is fixed at one end of the transmission cross shaft 323 outside the housing 1. A ratchet wheel 325 is fixed in the middle of the transmission cross shaft 323. A ratchet pawl 326 is meshed with one side of the ratchet wheel 325. One end of the ratchet pawl 326 is rotatably provided with a limit post fixed to the housing 1. Due to the setting of the ratchet pawl 326, the ratchet wheel 325 can only rotate in one direction, thereby keeping the transmission cross shaft 323 rotating in only one direction, and further improving the stability of clamping and fixing the wire harness.

[0047] By rotating the spiral cap 324, the spiral cap 324 drives the transmission cross shaft 323 on its side to rotate. The transmission cross shaft 323 drives the transmission gear 321 at one end of it to rotate. The transmission gear 321 drives the second rack 322 at its bottom to move. The second rack 322 drives the strip-shaped rod 31 to move inside the housing 1, enabling maintenance personnel to fix and disassemble the wire harness more conveniently and quickly, and reducing the complexity during the maintenance process.

[0048] The fourth embodiment

[0049] In order to make the movement of the strip-shaped rod 31 more stable and not deviate, as Figure 1- Figure 7 As shown in Figure 7 , for the limiting member 33 of the first embodiment, specifically in the implementation manner, the limiting member 33 includes a sliding transverse groove 331 formed in the strip-shaped rod 31. A positioning cross rod 332 is slidably disposed inside the sliding transverse groove 331. Support seats 333 fixed to the inner bottom wall of the housing 1 are respectively fixed at both ends of the positioning cross rod 332. The strip-shaped rod 31 slides outside the positioning cross rod 332, and the sliding transverse groove 331 is set at a certain distance, which can achieve precise clamping control. The moving direction and length of the strip-shaped rod 31 are limited, ensuring that the moving range and clamping force of the two arc-shaped clamping rods 21 are controllable, and avoiding problems of over-clamping or insufficient clamping.

[0050] In the present invention, three wire harnesses are separately fixed by three sets of clamping members 2. When it is necessary to repair or replace a wire harness, the three sets of clamping members 2 are simultaneously opened. The two arc-shaped clamping rods 21 are synchronously driven by the transmission member 23 to open towards both ends. Since the wire harnesses lack fixation, one or more wire harnesses can be repaired or replaced, reducing the interference to other wire harnesses and the inconvenience during the maintenance process.

[0051] During the use of this wire management and positioning clip, the three wire harnesses to be fixed are respectively placed in the three sets of clamping members 2, and each wire harness is located between the two arc-shaped clamping rods 21. Then, the screw cap 324 is rotated. The screw cap 324 drives the transmission cross shaft 323 on one side thereof to rotate. The transmission cross shaft 323 drives the transmission gear 321 at one end thereof to rotate. The transmission gear 321 drives the second rack 322 at its bottom to move. The second rack 322 drives the strip-shaped rod 31 to move outside the positioning cross rod 332. The strip-shaped rod 31 drives the three first racks 236 thereon to move. The first rack 236 drives the driving gear 234 at its top to rotate. The driving gear 234 drives the driven gear 235 engaged therewith to rotate, thereby simultaneously driving the two limiting rotating shafts 233 to rotate. The two limiting rotating shafts 233 respectively drive the two arc-shaped clamping rods 21 to rotate towards the middle to clamp the wire harnesses;

[0052] At the same time, the limiting rotating shaft 233 drives the threaded shafts 243 at both ends thereof to rotate. The threaded shafts 243 drive the threaded sleeves 242 thereon to move. The threaded sleeves 242 drive the limiting bearings 241 outside them to move, so that the limiting bearings 241 enter the limiting grooves, thereby further limiting the arc-shaped clamping rods 21 on the housing 1.

[0053] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
