[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment proposes a wheel speed sensor harness fixing device and an unmanned vehicle to solve the problem of easy damage to wheel speed sensor harnesses in the prior art.

[0037] like Figure 1As shown, a wheel speed sensor harness fixing device is installed on an unmanned vehicle. The wheel speed sensor harness fixing device includes a first fixing bracket 1 and a second fixing bracket 2. The first fixing bracket 1 has a mounting member 11 and a positioning member 12 connected to the mounting member 11. The mounting member 11 is used to connect to the axle 200 of the unmanned vehicle. The positioning member 12 has a mounting hole. One end of the second fixing bracket 2 is used to connect to the axle 200 of the unmanned vehicle, and the other end has a mounting hole. The wheel speed sensor harness fixing device also includes a plurality of fixing members 3, which are installed one-to-one in the mounting holes of the first fixing bracket 1 and the second fixing bracket 2. The fixing members 3 have a wire through hole 311 for the wheel speed sensor harness 400 to pass through.

[0038] Understandably, by setting a first fixed bracket 1 and a second fixed bracket 2 on the axle 200, with mounting holes on the first fixed bracket 1 and the second fixed bracket 2, the positioning part 31 of the fixing member 3 can fix the wheel speed sensor harness 400. The fixing member 3 is installed one-to-one in the mounting holes, thereby positioning the wheel speed sensor harness 400 on the axle 200. This eliminates the need for workers to find the positioning position of the wheel speed sensor harness 400 based on experience, improving assembly efficiency and avoiding the problem of unreasonable harness positioning caused by manually finding the positioning position of the wheel speed sensor harness 400, which could lead to pulling damage. In addition, by positioning the wheel speed sensor harness 400 on the axle 200 with the first fixed bracket 1 and the second fixed bracket 2, the problem of the wheel speed sensor harness 400 swinging freely and interfering with other components during the operation of the unmanned vehicle is avoided, further reducing the probability of damage to the wheel speed sensor harness 400 and improving the user experience.

[0039] Optionally, the axes of both wire holes 311 are parallel to the axis of the axle 200. This arrangement facilitates the parallel passage of the wheel speed sensor wiring harness 400 through the wire holes 311, preventing damage to the wheel speed sensor wiring harness 400 due to bending and improving the reliability of the wheel speed sensor wiring harness 400.

[0040] Optionally, the mounting holes of the first fixing bracket 1 and the second fixing bracket 2 are perpendicular in axis. This arrangement allows the fixing members 3 at different installation positions to have different orientations, thereby making it less likely for the wheel speed sensor harness 400 to fall out of the wire hole 311 and improving the reliability of the wheel speed sensor harness fixing device.

[0041] like Figures 1-2 As shown, optionally, a groove is provided on the lower side of the mounting component 11, the cross-section of which is arc-shaped, and the arc-shaped groove abuts against the upper side of the axle 200. This configuration improves the fit between the mounting component 11 and the axle 200, reduces the stress generated by the first fixed bracket 1 during the operation of the unmanned vehicle, and improves the reliability of the wheel speed sensor harness fixing device.

[0042] Optionally, two positioning elements 12 are provided, and the two positioning elements 12 are connected to both sides of the mounting element 11. This arrangement facilitates the effective positioning of the wheel speed sensor wiring harnesses 400 on both sides of the axle 200, improving the structural rationality of the wheel speed sensor wiring harness fixing device.

[0043] Optionally, the positioning member 12 is L-shaped, with one leg of the L-shaped positioning member 12 mounted on the mounting member 11, and the other leg extending downward and having a mounting hole. This arrangement allows the first fixing bracket 1 to fit as close as possible to the outer periphery of the axle 200, reducing space occupation and further preventing interference between the wheel speed sensor wiring harness 400 and other components after installation. In addition, this arrangement ensures that the wheel speed sensor wiring harness 400 can be effectively fixed when passing through both sides of the axle 200, preventing the wheel speed sensor wiring harness 400 from swinging or interfering with other components.

[0044] Optionally, the second fixed bracket 2 is plate-shaped, and the thickness direction of the second fixed bracket 2 is parallel to the vertical direction. This configuration reduces the size and weight of the second fixed bracket 2, thereby improving the portability of the autonomous vehicle.

[0045] Optionally, two second fixing brackets 2 are provided, and the two second fixing brackets 2 are installed one-to-one on both sides of the axle 200 along the length direction of the unmanned vehicle. This arrangement ensures that the second fixing brackets 2 correspond to the positioning members 12 on both sides of the axle 200, which can further ensure that the wheel speed sensor harness 400 can be effectively fixed when passing through both sides of the axle 200, and further avoid the wheel speed sensor harness 400 swinging or interfering with other components.

[0046] like Figure 3 As shown, optionally, the fixing member 3 includes a positioning part 31 and a connecting part 32 connected to each other. The connecting part 32 is installed in the mounting holes of the first fixing bracket 1 and the second fixing bracket 2 respectively. The positioning part 31 has a wire through hole 311. This configuration improves the structural rationality of the fixing member 3, thereby improving the reliability of the wheel speed sensor wiring harness fixing device.

[0047] Optionally, the connecting part 32 includes a connecting rod structure 321 and a flexible locking structure 322. The flexible locking structure 322 is disposed on the outer periphery of the connecting rod structure 321. The connecting rod structure 321 and the flexible locking structure 322 can pass through the mounting hole, and the diameter of the flexible locking structure 322 is larger than the diameter of the mounting hole.

[0048] Understandably, during the process of the connecting rod structure 321 passing through the mounting hole, the flexible locking structure 322 abuts against the mounting hole and is compressed by the mounting hole until it returns to a relaxed state after passing through the mounting hole, thereby simply and quickly positioning the connecting part 32 in the mounting hole and improving the assembly efficiency of the wheel speed sensor harness 400.

[0049] For example, the flexible locking structure 322 is tapered and coaxially connected to the connecting rod structure 321, with the larger end of the flexible locking structure 322 facing the positioning part 31. This arrangement makes it easier for the flexible locking structure 322 to enter the mounting hole and more difficult to exit it, improving the positioning reliability of the fastener 3 for the wheel speed sensor harness 400.

[0050] For example, multiple flexible locking structures 322 are provided, and the multiple flexible locking structures 322 are spaced apart from the connecting rod structure 321. This arrangement can form multi-level limiting of the connecting rod structure 321, can change the insertion depth of the connecting part 32 into the mounting hole as needed, and can further prevent the connecting part 32 from dislodging from the mounting hole, thereby improving the reliability of the wheel speed sensor harness fixing device.

[0051] For example, the flexible locking structure 322 is made of polytetrafluoroethylene (PTFE). This design improves the cold resistance, heat resistance, and corrosion resistance of the flexible locking structure 322, thereby enhancing its reliability. Of course, in other embodiments, the flexible locking structure 322 can also be made of other materials, depending on actual needs, and no further restrictions are imposed here.

[0052] Optionally, the connecting part 32 further includes a flexible abutment plate structure 323, which is coaxially disposed at one end of the connecting rod structure 321 near the positioning part 31. The flexible abutment plate structure 323 can abut against the second fixed bracket 2 or the positioning member 12. This arrangement allows the flexible abutment plate structure 323 to cooperate with the flexible locking structure 322 to clamp the second fixed bracket 2 or the positioning member 12 from both sides, thereby improving the fixing strength of the fixing member 3.

[0053] Optionally, the positioning element 12 is plate-shaped. This arrangement reduces the weight and space occupied by the first fixing bracket 1, thereby improving the portability of the wheel speed sensor harness fixing device.

[0054] Optionally, the diameter of the wire hole 311 is larger than the diameter of the wheel speed sensor wiring harness 400. This arrangement allows the wheel speed sensor wiring harness 400 to move and swing within the wire hole 311 to a certain extent, thereby preventing the wheel speed sensor wiring harness 400 from being torn off due to overly tight positioning during autonomous vehicle operation and improving the reliability of the wheel speed sensor wiring harness fixing device.

[0055] For example, the positioning part 31 has a locking channel and also includes a cable tie. The cable tie can pass through the locking channel to form a wire hole 311. Multiple abutment structures are spaced apart on the cable tie, and a backstop structure is provided in the locking channel. Any abutment structure can abut against the backstop structure. This arrangement uses a cable tie to fix the wheel speed sensor wiring harness 400, which is simple to operate and low in cost, thus improving the economy of the wheel speed sensor wiring harness fixing device.

[0056] It should be noted that the positioning part 31 can adopt any commercially available cable tie locking method, which is not the focus of protection in this embodiment and will not be elaborated on here.

[0057] This embodiment also provides an unmanned vehicle to solve the problem of easy damage to the wheel speed sensor wiring harness 400 in the prior art. The unmanned vehicle proposed in this embodiment includes wheels 100, a frame 300, an axle 200, wheel speed sensors, and wheel speed sensor wiring harness 400. The axle 200 is mounted on the frame 300, and wheels 100 are mounted on both ends of the axle 200. The wheel speed sensor is mounted on the wheel 100 and connected to the wheel speed sensor wiring harness 400. The unmanned vehicle also includes a wheel speed sensor wiring harness fixing device. Mounting holes are provided on the frame 300, and the fixing member 3 can be installed in the mounting holes of the frame 300.

[0058] This embodiment proposes an unmanned vehicle that, by setting up a wheel speed sensor harness fixing device, can position the wheel speed sensor harness 400 on the axle 200. This eliminates the need for workers to find the wheel speed sensor harness 400's location based on experience, improving assembly efficiency. It also avoids the problem of improper harness positioning caused by manual searching for the wheel speed sensor harness 400's location, which could lead to damage. Furthermore, it prevents the wheel speed sensor harness 400 from swinging freely and interfering with other components during unmanned vehicle operation, further reducing the probability of damage to the wheel speed sensor harness 400 and improving the user experience.

[0059] Furthermore, the unmanned vehicle proposed in this embodiment has mounting holes on the frame 300, in which the fixing member 3 can be installed to position the wheel speed sensor wiring harness 400. This prevents the wheel speed sensor wiring harness 400 from swinging on the frame 300, avoids interference with other components on the frame 300, and thus avoids damage to the wheel speed sensor wiring harness 400, thereby improving the user experience.

[0060] The usage process of the wheel speed sensor harness fixing device in this embodiment is as follows:

[0061] First, the optimal fixing position of the wheel speed sensor harness 400 was determined by experiment, and the mounting holes on the first fixing bracket 1, the second fixing bracket 2 and the frame 300 were installed or opened on the chassis of the unmanned vehicle according to the pre-designed fixing position.

[0062] Next, the wheel speed sensor wiring harness 400 is threaded through the wire hole 311 of the fixing member 3, and the wire hole 311 is tightened to the preset size according to actual needs;

[0063] Insert the connecting parts 32 of each fixing component 3 into the mounting holes of the first fixing bracket 1, the second fixing bracket 2, and the mounting holes on the frame 300 to complete the fixing of the wheel speed sensor wiring harness 400.

[0064] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
