Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a high-stability protection mechanism for an automobile wheel speed wire harness. Background Art

[0002] A wheel speed sensor, namely a vehicle speed sensor, is used to detect the rotational speed of a wheel and convert it into an electrical signal for input to a control unit ECU. For modern automobiles, wheel speed information is essential, and it is required for automotive dynamic control systems, electronic stability programs, anti-lock braking systems, etc. Currently, when most wheel speed sensors are arranged, the wire harness of the wheel speed sensor needs to be bundled with a brake hose.

[0003] When the existing wire harness of the wheel speed sensor is arranged, its two ends usually need to be fixed. When the wire harness is arranged tightly, there is no buffer space when it is subjected to external forces, resulting in the wire harness being easily damaged or even broken. When the wire harness is arranged relatively loosely, it may rub against the body such as the wheel hub during use, causing wear and affecting the stability and service life of the wire harness. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-stability protection mechanism for an automobile wheel speed wire harness, which solves the technical problems raised in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-stability protection mechanism for an automobile wheel speed wire harness, including two connecting seats and a wire harness. The inner walls of the two connecting seats are symmetrically provided with side grooves. An activity plate is slidably connected between the two side grooves. The front end of the wire harness is fixedly connected to the front activity plate. A positioning component is sleeved on the outer wall of the wire harness. A check component is arranged inside the positioning component. The rear end of the wire harness passes through the check component and is connected to the rear activity plate. The positioning component is composed of a positioning ring one and a positioning ring two. The positioning ring one and the positioning ring two are detachably connected through a connecting component.

[0006] Preferably, the check component includes a check ring and a snap ring. The check ring is wider at the front and narrower at the rear. A notch is opened at the rear end of the check ring. The check ring is made of rubber.

[0007] Preferably, the connecting component includes a bolt. The outer walls of the positioning ring one and the positioning ring two are symmetrically provided with grooves. The positioning ring one and the positioning ring two are threadedly connected through the bolt. The bolt is located inside the groove.

[0008] Preferably, a ring groove is opened on the inner wall of the positioning ring one. The snap ring is rotatably installed inside the ring groove. The check component is connected to the positioning component through the snap ring.

[0009] Preferably, an arc-shaped opening is formed at the rear end of the first positioning ring, the arc-shaped opening is communicated with the annular groove, and a limiting ring is fixedly connected to the rear end of the first positioning ring;

[0010] A limiting groove is formed at the front end of the second positioning ring, the limiting ring is inserted into the limiting groove, an inclined groove is formed at the front end of the second positioning ring, and fixing blocks are symmetrically connected to the outer walls of the first positioning ring and the second positioning ring.

[0011] Preferably, a telescopic rod is fixedly connected to the inner wall of each side groove, the inner wall of the movable plate is slidably connected to the outer wall of the telescopic rod, springs are fixedly connected to the front and rear ends of the movable plate, the springs are located outside the telescopic rod, and one end of the spring away from the movable plate is fixedly connected to the inner wall of the side groove.

[0012] Compared with the related art, a high-stability protection mechanism for an automotive wheel speed wire harness provided by the present utility model has the following beneficial effects:

[0013] 1. During use, the positioning component is fixed on the vehicle body, the wire harness is passed through the positioning component and connected to the movable plates on the two connecting seats, and its two ends are properly tightened to prevent the wire harness from loosening. After the wire harness is connected, when the wire harness is subjected to a pulling force, the movable plate at its end will slide back and forth in the connecting seat, and the spring provides a buffering force and an elastic force to reserve a moving space for the wire harness, so as to prevent the wire harness from breaking when encountering a huge pulling force. While ensuring safety, it can effectively prevent the wire harness from loosening and improve the service life of the wire harness.

[0014] 2. The check ring itself is wider at the front and narrower at the rear, and is made of rubber material and has elasticity. The aperture at its rear end is smaller than the diameter of the wire harness, so that it can be tightened in time when the wire harness passes through the check ring. The cut ensures that the rear end of the check ring can expand outwards. When the wire harness passes through the check ring, a damping effect is achieved through the frictional force between the two, effectively enhancing the fit between the two, so as to prevent the wire harness from loosening and rubbing against the vehicle body to cause wear.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment:

[0027] Please refer to Figure 1 - Figure 9 , the present utility model provides a technical solution: a high-stability automotive wheel speed wire harness protection mechanism, including two connecting seats 1 and a wire harness 6. Side grooves 2 are symmetrically opened on the inner walls of the two connecting seats 1. A movable plate 5 is slidably connected between the two side grooves 2. The front end of the wire harness 6 is fixedly connected to the front movable plate 5. A positioning component 7 is sleeved on the outer wall of the wire harness 6. An anti-backflow component 8 is arranged inside the positioning component 7. The rear end of the wire harness 6 passes through the anti-backflow component 8 and is connected to the rear movable plate 5. The positioning component 7 is composed of a first positioning ring 701 and a second positioning ring 702. The first positioning ring 701 and the second positioning ring 702 are detachably connected through a connecting component;

[0028] Before use, disassemble the positioning component 7, then snap the snap ring 802 at the front end of the check ring 801 into the inner part of the ring groove 705, then assemble the positioning component 7 together and fix it on the vehicle body. The positioning component 7 is connected by bolts 709, which facilitates disassembly and assembly. During use, fix one end of the wire harness 6 on the movable plate 5, then pass the other end of the wire harness 6 through the positioning component 7 and connect it to the movable plate 5 on another connecting seat 1, so as to position the end of the wire harness 6. When the wire harness 6 passes through the positioning component 7, the check ring 801 can play a limiting role on the wire harness 6, thus preventing the wire harness 6 from loosening;

[0029] The inner wall of each side groove 2 is fixedly connected with a telescopic rod 3, and the inner wall of the movable plate 5 is slidably connected with the outer wall of the telescopic rod 3. Both the front and rear ends of the movable plate 5 are fixedly connected with springs 4. The springs 4 are located outside the telescopic rods 3, and the ends of the springs 4 far away from the movable plate 5 are fixedly connected with the inner wall of the side groove 2. When the wire harness 6 is subjected to a pulling force, the movable plate 5 at its end will slide back and forth in the connecting seat 1, and the spring 4 provides a buffering force, reserving a moving space for the wire harness 6 to prevent the wire harness 6 from breaking when encountering a huge pulling force and improving safety;

[0030] The check component 8 includes a check ring 801 and a snap ring 802. The check ring 801 is wider at the front and narrower at the rear. A notch 803 is opened at the rear end of the check ring 801. The check ring 801 is made of rubber and has elasticity. The aperture at its rear end is smaller than the diameter of the wire harness 6, so as to tighten in time when the wire harness 6 passes through the check ring 801. The notch 803 ensures that the rear end of the check ring 801 can expand outwards, and when the wire harness 6 passes through the check ring 801, a damping effect is achieved through the friction between the two, increasing the fitting degree between the two;

[0031] The connecting component includes a bolt 709. Grooves 708 are symmetrically formed on the outer walls of the first positioning ring 701 and the second positioning ring 702. The first positioning ring 701 and the second positioning ring 702 are threadedly connected by the bolt 709. The positioning component 7 composed of the first positioning ring 701 and the second positioning ring 702 can be connected together by the bolt 709. The bolt 709 is located inside the groove 708. An annular groove 705 is formed on the inner wall of the first positioning ring 701. The snap ring 802 is rotatably installed inside the annular groove 705. The check component 8 is connected to the positioning component 7 through the snap ring 802. An arc-shaped opening 706 is formed at the rear end of the first positioning ring 701. The arc-shaped opening 706 communicates with the annular groove 705. A limit ring 703 is fixedly connected to the rear end of the first positioning ring 701. A limit groove 704 is formed at the front end of the second positioning ring 702. The limit ring 703 is inserted into the limit groove 704. An inclined groove 707 is formed at the front end of the second positioning ring 702. Fixed blocks 710 are symmetrically connected to the outer walls of the first positioning ring 701 and the second positioning ring 702. The check ring 801 is of a front-wide-and-rear-narrow type. The design of the arc-shaped opening 706 and the inclined groove 707 provides an installation space for it. When the first positioning ring 701 and the second positioning ring 702 are butted, the limit ring 703 is inserted into the limit groove 704, improving the tightness between the two and enhancing the strength of the positioning component 7 itself.

[0032] Working principle: Before use, disassemble the positioning component 7, then snap the snap ring 802 at the front end of the check ring 801 into the inside of the annular groove 705, and then assemble the positioning component 7 together and fix it on the vehicle body. When in use, fix one end of the wire harness 6 on the movable plate 5, then pass the other end of the wire harness 6 through the positioning component 7 and connect it to the movable plate 5 on another connecting seat 1 to achieve the effect of positioning the end of the wire harness 6. When the wire harness 6 passes through the positioning component 7, the check ring 801 plays a limiting role on the wire harness 6 to prevent the wire harness 6 from loosening. When the wire harness 6 is subjected to a pulling force, the movable plate 5 at its end will slide back and forth in the connecting seat 1, and the spring 4 provides a buffering force to reserve a movable space for the wire harness 6 to prevent the wire harness 6 from breaking when encountering a huge pulling force. The check ring 801 is of a front-wide-and-rear-narrow type and is made of rubber material and has elasticity. The aperture at its rear end is smaller than the diameter of the wire harness 6, so as to be tightened in time when the wire harness 6 passes through the check ring 801. The cut 803 ensures that the rear end of the check ring 801 can expand outwards, and when the wire harness 6 passes through the check ring 801, a damping effect is achieved through the friction between the two, increasing the degree of fit between the two to prevent the wire harness 6 from moving inside the positioning component 7 and reducing the wear between the wire harness 6 and the vehicle body.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
