[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0047] Please refer to Figures 1-5 , the embodiments provided by the present utility model:

[0048] Embodiment 1

[0049] As Figure 1 and Figure 2As shown in the figure, a fixing member for a wheel speed sensor wire harness fixes the wire harness 5 to the vehicle body or other structures, which can prevent the wire harness 5 from swinging and falling off. It includes a mounting plate 1 and a clamping plate 2. The mounting plate 1 and the clamping plate 2 are integrally formed. The mounting plate 1 and the clamping plate 2 are vertically bent. In order to enable the clamping plate 2 to be clamped with the side wall of the wire harness 5, the mounting plate 1 can be fixedly installed on the vehicle body, so as to prevent the wire harness 5 from being restricted due to the limitation of the installation position. A clamping hole 4 for clamping with the wire harness 5 is opened at the end of the clamping plate 2;

[0050] Specifically, the clamping hole 4 includes an annular hole 41 for surrounding the wire harness groove 51 opened on the side wall of the wire harness 5, a notch 43 opened on the side of the annular hole 41. The notch 43 and the annular hole 41 are communicated. And a return hook groove 42 for preventing the fixing member from detaching from the side wall of the wire harness 5 is provided in the transition area from the notch 43 to the annular hole 41. A sliding inclined groove 44 for facilitating sliding with the side wall of the wire harness 5 is provided at a position of the notch 43 close to the side wall of the clamping plate 2.

[0051] Due to the opening of the notch 43, the side wall of the clamping plate 2 is open, so that the wire harness groove 51 on the side wall of the wire harness 5 can be inserted into the annular hole 41. And the setting of the annular hole 41 can also provide space for the clamping of the wire harness 5 according to the arc-shaped side wall of the wire harness 5. During specific installation, align the notch 43 of the clamping plate 2 with the wire harness groove 51 opened on the wire harness 5, and then forcefully squeeze the clamping plate 2 on the wire harness groove 51 of the wire harness 5, so that the wire harness groove 51 enters the notch 43 under the guiding action of the inclined groove 44. As the clamping plate 2 is pushed, the wire harness groove 51 on the side wall of the wire harness 5 is placed in the annular hole 41, so that the clamping plate 2 is clamped on the side wall of the wire harness 5 to provide a supporting position for the wire harness 5. And due to the setting of the return hook groove 42, when the wire harness 5 is pulled out of the annular hole 41 under the action of an external force, the return hook groove 42 effectively prevents the wire harness 5 from being pulled out. And a relatively large pulling force is required until the wire harness groove 51 of the wire harness 5 is deformed and extruded from the return hook groove 42 into the notch 43 to be able to remove the wire harness 5 from the fixing member, thus avoiding the situation that the wire harness 5 is pulled out of the fixing member due to vibration or shaking during vehicle driving, resulting in the wire harness 5 of the wheel speed sensor falling near the vehicle body wheel.

[0052] Mounting holes 3 are opened on the top surface of the mounting plate 1. If the mounting plate 1 coincides with the position to be installed on the predetermined vehicle, the fixing member is directly installed at the mounting position on the bottom surface of the vehicle body through the threaded fastener 7 cooperating with the mounting holes 3 to support and fix the wire harness 5.

[0053] Embodiment 2

[0054] As Figure 3As shown, on the basis of Embodiment 1, in order to be able to cope with the misalignment between the installation position and the installation hole 3, the installation hole 3 is installed with the adjusting plate 6 through a threaded fastener 7. The adjusting plate 6 has an "L" - shaped structure. A fixing hole 61 is opened on the side wall in the vertical direction of the adjusting plate 6, and an oblong hole 62 is penetrated through the top surface in the horizontal direction of the adjusting plate 6.

[0055] The installation hole 3 on the installation plate 1 and the oblong hole 62 on the adjusting plate 6 are fixedly installed through a threaded fastener 7. A limiting plate 63 is fixedly connected to the side wall in the horizontal direction of the adjusting plate 6, and the limiting plates 63 are respectively located beside the two side walls of the installation plate 1.

[0056] There can be sliding between the oblong hole 62 on the additional adjusting plate 6 and the installation hole 3 when the threaded fastener 7 is in a loose state. Thus, after adjusting the position of the screw rod of the threaded fastener 7 in the oblong hole 62 according to the actual required installation position, the position of the adjusting plate 6 on the fixing part can be adjusted, and then the threaded fastener 7 is tightened to fix the position between the adjusting plate 6 and the fixing part. Thus, it is installed on the preset hole position of the vehicle body through the cooperation of the fixing hole 61 on the adjusting plate 6 and the threaded fastener 7, which is convenient for the installation of the fixing part.

[0057] Embodiment 3

[0058] As Figures 4-5 shown, on the basis of Embodiment 1 and Embodiment 2, in order to prevent the situation that the connection position of the wire harness 5 of the installation fixing part is bent and causes the fixing part to fall off from the wire harness 5, connecting plates 8 are respectively fixedly connected to both sides of the clamping plate 2, and auxiliary support components 9 for preventing the wire harness 5 from bending are respectively installed on the connecting plates 8 through threaded fasteners 7.

[0059] Specifically, the auxiliary support component 9 includes a sliding mechanism and a wire clamping mechanism. The wire clamping mechanism is fixedly installed at the bottom end of the sliding mechanism. The sliding mechanism includes a support plate 91, a vertical plate 93, a sliding plate 94, a lead screw 96 and a nut 95. The vertical plate 93 is integrally formed with the support plate 91 and is vertically arranged on one side of the support plate 91. The side wall of the vertical plate 93 abuts against the two side walls of the clamping plate 2. A through - hole is opened on one side of the top surface of the support plate 91, and the through - hole opened on the support plate 91 and the through - hole on the connecting plate 8 are fixedly installed through a threaded fastener 7.

[0060] A chute 92 is penetrated through the top surface of the support plate 91. The lead screw 96 is slidably connected in the chute 92. The top end of the lead screw 96 is fixedly connected to the sliding plate 94. Flanging is provided on both sides of the sliding plate 94, and the flanging is slidably connected to the two side walls of the support plate 91. The side wall of the lead screw 96 is internally threaded with the nut 95, and the top surface of the nut 95 abuts against the bottom surface of the support plate 91.

[0061] By loosening or tightening the nut 95, the slide plate 94 and the lead screw 96 can slide on the top surface of the support plate 91 and in the chute 92 to adjust the position of the wire clamping mechanism to the limiting groove of the wire harness 5, so as to adjust according to the opening position of the wire groove 51 of the specific wire harness 5, and increase the versatility of the fixing parts.

[0062] The wire clamping mechanism includes an upper clamping plate 97 and a lower clamping plate 910. The bottom end of the lead screw 96 is fixedly connected to one side of the top surface of the upper clamping plate 97. A clamping groove 914 for clamping on the side wall of the wire harness 5 is formed at one end where the upper clamping plate 97 and the lower clamping plate 910 face each other.

[0063] One side of the bottom surface of the upper clamping plate 97 is fixedly connected with slide rods 98 respectively. Slide holes 911 are formed in the lower clamping plate 910 at positions corresponding to the slide rods 98. The slide holes 911 are slidably connected to the side walls of the slide rods 98. A limiting disc 913 is fixedly installed at the bottom end of the slide rods 98. A spring 912 is sleeved on the side wall of the slide rod 98 between the limiting disc 913 and the bottom surface of the lower clamping plate 910.

[0064] It is clamped on the side wall of the wire harness 5 through the clamping grooves 914 on the upper clamping plate 97 and the lower clamping plate 910, so as to prevent the wire harness 5 at the installation position of the auxiliary clamping hole 4 from being easily bent. At the same time, by sliding the lower clamping plate 910 on the side wall of the slide rod 98 and the compression and expansion movement of the spring 912, the size of the clamping groove 914 can be adjusted according to the diameter of different wire harnesses 5.

[0065] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
