[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 9 This utility model provides a technical solution: a fixing device for wheel speed sensor wiring harness of new energy vehicle, including an L-shaped support plate 1, a plurality of through holes 2 for the wiring harness to pass through on the outer wall of the support plate 1, and an installation cavity 3 in the inner wall of the through holes 2. The mounting cavity 3 is equipped with a fixing mechanism 4 for securely clamping the wire harness.

[0017] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixing mechanism 4 includes a bearing ring 41 on the same axis as the mounting cavity 3. Both ends of the bearing ring 41 are fixedly connected to protruding rings 42, and the two protruding rings 42 are respectively fixedly connected to the inner walls of the two through holes 2 on both sides of the mounting cavity 3. Both the protruding rings 42 and the bearing ring 41 have wire holes. A rotating ring 43 is movably sleeved on the outer peripheral wall of the bearing ring 41, and one end of the rotating ring 43 is rotatably connected to the inner wall of the mounting cavity 3. The bearing ring 41 is provided with a clamping member 44 for clamping the wire harness; The rotating ring 43 is provided with a trigger element 45 for triggering the clamping function, so that the rotating ring 43 can slide stably on the bearing ring 41 and avoid interference movement.

[0018] In this embodiment, as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the clamping member 44 includes vertical grooves 441 formed inside the bearing ring 41, and several vertical grooves 441 are arranged in a circular array at equal intervals. Both ends of the vertical groove 441 are provided with sliding grooves 442, and a horizontally arranged guide rod 443 passes through the inside of the sliding groove 442. The guide rod 443 moves vertically on the bearing ring 41 through the sliding groove 442. A connecting plate 445 is slidably arranged on the guide rod 443. The connecting plate 445 is located in the vertical groove 441. The connecting plate 445 is a spring telescopic plate structure. A rubber plate 446 is fixedly connected to the bottom end of the connecting plate 445. When the rubber plate 446 is in contact with and squeezed against the wire harness, the spring telescopic plate structure on the connecting plate 445 makes it easy for the rubber plate 446 to continuously contact and squeeze the wire harness, thereby increasing the fixing effect.

[0019] In this embodiment, as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the clamping member 44 also includes an arc-shaped groove 447 formed on the inner side wall of the rotating ring 43. The arc-shaped groove 447 is slidably connected to the side wall of the guide rod 443. Several arc-shaped grooves 447 are arranged in a circular array at equal intervals, and each arc-shaped groove 447 corresponds to a vertical groove 441. The left end of the guide rod 443 has an internal movable cavity 448, and the right end of the guide rod 443 has a number of equally spaced circularly arranged movable slots 449. The inner walls of the movable slots 449 are all fixedly connected to protrusions 4410. The interior of the movable slots 449 is slidably connected to movable plates 4411. The movable plates 4411 have guide slots 4412 that are slidably connected to the protrusions 4410. A conical rod 4416 is inserted into the guide rod 443. The conical rod 4416 and the moving plate 4411 are set horizontally. The conical inclined surface on the conical rod 4416 pushes several moving plates 4411 to rise, thereby squeezing and limiting the arc groove 447.

[0020] In this embodiment, as Figure 7 and Figure 9 As shown, a connecting plate 4413 is vertically slidably connected to the top of the movable plate 4411, and an air cushion block 4414 is fixedly connected to the top of the connecting plate 4413. The interiors of both the movable plate 4411 and the connecting plate 4413 are hollow, and the air cushion block 4414 is filled with gas. The air cushion block 4414 is connected to the connecting plate 4413. By contracting and moving the movable plate 4411 and the connecting plate 4413, the sealing space between the movable plate 4411 and the connecting plate 4413 is reduced, which increases the air pressure between the movable plate 4411, the connecting plate 4413 and the air cushion block 4414. This causes the air cushion block 4414 to expand and fit tightly against the inner wall of the arc groove 447, preventing the guide rod 443 from loosening.

[0021] In this embodiment, as Figure 3 , Figure 5 and Figure 7 As shown, the length of the connecting plate 445 is less than the length of the vertical groove 441, and damping rods 4415 are fixedly connected to both ends of the connecting plate 445. The two ends of the damping rods 4415 pass through the sliding grooves 442 respectively, and connecting blocks are fixedly connected to the outer wall of the damping rods 4415. The connecting blocks are fixedly connected to the outer wall of the guide rod 443, so that the connecting plate 445 can float left and right on the guide rod 443, which reduces the pulling force generated when the wire harness is pulled and reset, and avoids damage to the wire harness.

[0022] In this embodiment, as Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the trigger 45 includes a sliding groove 451 formed on the outer wall of the guide rod 443. The sliding groove 451 is connected to the movable cavity 448. A control plate 452 fixedly connected to the conical rod 4416 is slidably arranged inside the sliding groove 451. The control plate 452 is connected to the inner wall of the movable cavity 448 by a tension spring. A push ring 453 is fixedly connected to the top of the control plate 452. The push ring 453 is horizontally slidably connected to the inner wall of the mounting cavity 3. An operation window 454 is provided on the outer wall of the support plate 1, which is horizontally arranged with the rotating ring 43. A locking groove is provided on the outer wall of the support plate 1. A locking plate 455 is vertically slidably connected inside the locking groove. A rod 456 is fixedly connected to the front end of the locking plate 455. The bottom end of the rod 456 is tapered, and a compression spring is sleeved on the top end of the rod 456. The top of the push ring 453 has a insertion hole for insertion into the insertion rod 456. The outer side wall of the rotating ring 43 may have an uneven friction surface, so that the operator can insert his thumb through the operating window 454 to rotate the rotating ring 43. When the rotating ring 43 is rotated into place, the operator can move his thumb to squeeze the push ring 453, so that the push ring 453 drives the conical rod 4416. After the push ring 453 moves into place, the insertion rod 456 slides down into the insertion hole, thereby locking all components.

[0023] like Figures 1 to 9 As shown, the working process of the fixing device for the wheel speed sensor harness of this new energy vehicle is as follows: The operator can pass the wire harness through the wire hole on the protruding ring 42 and remove it. Then, the operator inserts his thumb into the operating window 454 and uses his thumb to rotate the rotating ring 43. Several arc-shaped grooves 447 on the rotating ring 43 drive several guide rods 443 to slide on the bearing ring 41 through the sliding groove 442. The guide rods 443 simultaneously drive the connecting plate 445 and the rubber plate 446 to move down. Several rubber plates 446 contact the outer wall of the wire harness and continuously squeeze it, causing the rubber plates 446 to deform and wrap around the wire harness. After the rotation is completed, the rotating ring 43 can no longer be moved. The operator moves his thumb, and one end of his thumb contacts the pushing ring 453. The pushing ring 453 is squeezed forward and pushes the conical rod 4416 simultaneously. The control plate 452 pulls the tension spring. Then, the front conical surface of the conical rod 4416 squeezes the bottom of several moving plates 4411, causing the moving plates 4411 to move stably through the protrusion 4410 and the guide groove 4412, squeezing the air cushion block 4414 against the inner wall of the arc groove 447. At this time, through continuous squeezing, the connecting plate 4413 is drawn into the moving plate 4411. As the space between the moving plate 4411 and the connecting plate 4413 is reduced, the internal pressure increases, causing the air cushion block 4414 to expand, increasing the contact area with the inner wall of the arc groove 447 and increasing the restraining effect. At this time, the guide rod 443 can no longer move in the arc groove 447. At the same time, when the insertion rod 456 contacts the insertion hole, the insertion rod 456 falls into it by gravity and locks the push ring 453, thus completing the installation and fixing operation; When disassembly is required, similarly, simply move the locking plate 455 upward to move the insertion rod 456 out, and the push ring 453 is reset by the tension spring on the control plate 452. Several moving plates 4411 are no longer squeezed by the conical rod 4416, and thus return to their original state through internal air pressure. At this time, the guide rod 443 is no longer restricted and drives the rotating ring 43 in the opposite direction, so that it drives the guide rod 443 to rise through the arc groove 447 to release the clamping state. At this time, the wire harness can be pulled out.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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.
