Description

Technical Field

[0001] This utility model relates to the field of parking brake technology, specifically to a stable parking brake cable assembly. Background Technology

[0002] The parking brake cable assembly is one of the core components of the vehicle's parking brake system (commonly known as the handbrake or electronic handbrake). It is mainly used to transmit the operating force of the driver or electronic control unit to keep the vehicle stationary when parked.

[0003] In a parking brake cable assembly with a limiting function disclosed in the current authorized announcement CN204222836U, the cable assembly is covered by a limiting bracket assembly, the limiting bracket assembly is provided with a limiting hole, and the inner ring of the limiting hole is provided with a soft bushing; a section in the middle of the cable assembly is provided with a corrugated tube, the corrugated tube is equipped with a cable mounting bracket, the cable mounting bracket is fixed to the vehicle body, and the limiting bracket assembly is fixedly installed on the suspension control arm. The aforementioned device limits the range of cable movement during vehicle movement, allowing the cable to bounce within the limiting hole. By rationally selecting the bracket fixing position and the size of the bracket inner hole, the cable is stabilized while satisfying the motion envelope during the cable's up-and-down movement. A soft bushing is installed inside the limiting hole to protect the cable when it bounces within the limiting hole. However, while the soft bushing can reduce cable wear during bounce, the cable and the soft bushing of the limiting cable will also shift during the bounce, inevitably causing wear on the cable. Over time, the cable may even be worn out and damaged. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a stable parking brake cable assembly that prevents displacement between the cable and the limiting structure when the cable bounces, thereby avoiding cable wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable parking brake cable assembly, comprising a cable body, a limiting clamp being sleeved on the outer wall of the cable body, and a bolt being provided on one side of the limiting clamp, one end of the bolt penetrating the limiting clamp and being threadedly connected to the other side wall of the limiting clamp, a through hole being provided on one side of the limiting clamp, a fixing post being provided in the through hole, and an elastic support component being sleeved on the outer wall of the fixing post.

[0006] Preferably, the fixing post includes a slide rod that is slidably connected to the inner wall of the through hole, and one end of the slide rod is fixedly connected to a threaded rod, the outer wall of which is threaded with a nut.

[0007] Preferably, the elastic support assembly includes a threaded ring threadedly connected to the threaded rod, and a support spring is provided on one side of the threaded ring. A fixing block is fixedly connected to one end of the support spring, and one end of the fixing block is fixedly connected to the limiting clamp.

[0008] Preferably, the upper surface of the threaded ring is provided with an annular groove, and a fixed ring is rotatably connected to the inner wall of the annular groove, one end of which is fixedly connected to a support spring.

[0009] Preferably, a protective sleeve is provided inside the limiting clamp, and the protective sleeve is fitted onto the outer wall of the cable body.

[0010] Preferably, the outer wall of the threaded ring is provided with anti-slip texture.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a limiting clamp that works in conjunction with bolts to fix the cable body. An elastic support component supports both the limiting clamp and the cable body. When the cable body moves up and down, the moving cable body moves the limiting clamp along with it, preventing displacement between the limiting clamp and the cable body. This eliminates sliding friction between the limiting clamp and the cable body, preventing damage from friction. Furthermore, when the cable body moves up and down, the elastic support component converts some of the kinetic energy of the movement into elastic potential energy, thus reducing the vertical movement of the cable body.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1-4 A stable parking brake cable assembly includes a cable body 1, a limiting clamp 2 is sleeved on the outer wall of the cable body 1, and a bolt 3 is provided on one side of the limiting clamp 2. One end of the bolt 3 passes through the limiting clamp 2 and is threaded to the other side wall of the limiting clamp 2. A through hole is opened on one side of the limiting clamp 2, and a fixing post 4 is provided in the through hole. An elastic support component is sleeved on the outer wall of the fixing post 4.

[0016] As can be seen from the above structure: by setting the limiting clamp 2 and the bolt 3 together, the cable body 1 can be fixed. By setting the elastic support component, the limiting clamp 2 and the cable body 1 can be supported. When the cable body 1 jumps up and down, the jumping cable body 1 can drive the limiting clamp 2 to move together, so that the limiting clamp 2 will not be displaced from the cable body 1. This prevents sliding friction between the limiting clamp 2 and the cable body 1, so that the cable body 1 will not be damaged by friction. Moreover, when the cable body 1 jumps up and down, the elastic support component can convert part of the kinetic energy of the cable body 1 jumping up and down into the elastic potential energy of the elastic support component, thereby reducing the jumping of the cable body 1.

[0017] Furthermore, the fixed post 4 includes a slide rod 401 that is slidably connected to the inner wall of the through hole, and one end of the slide rod 401 is fixedly connected to a threaded rod 402, and the outer wall of the threaded rod 402 is threadedly connected to a nut 403; by setting the threaded rod 402 and the nut 403 to work together, the fixed post 4 can be fixed on the suspension swing arm, and the slide rod 401 can limit the clamp 2.

[0018] Furthermore, the elastic support assembly includes a threaded ring 5 that is threadedly connected to the threaded rod 402, and a support spring 6 is provided on one side of the threaded ring 5. A fixing block 7 is fixedly connected to one end of the support spring 6, and one end of the fixing block 7 is fixedly connected to the limiting clamp 2. By providing the support spring 6, the limiting clamp 2 can be supported. When the cable body 1 jumps up and down, the support spring 6 will deform, thereby converting part of the kinetic energy of the cable body 1 jumping up and down into elastic potential energy.

[0019] Furthermore, an annular groove 8 is provided on the upper surface of the threaded ring 5, and a fixed ring 9 is rotatably connected to the inner wall of the annular groove 8. One end of the fixed ring 9 is fixedly connected to the support spring 6. By setting the annular groove 8 and the fixed ring 9 to work together, when rotating the threaded ring 5, the support spring 6 can be prevented from pressing too tightly against the threaded ring 5, thus avoiding the problem of difficulty in rotating the threaded ring 5.

[0020] Furthermore, a protective sleeve 10 is provided inside the limiting clamp 2, and the protective sleeve 10 is fitted onto the outer wall of the cable body 1; by providing the protective sleeve 10, protection can be filled between the limiting clamp 2 and the cable body 1, thereby avoiding the problem that the limiting clamp 2 may pinch and damage the cable body 1 when fixing the cable body 1.

[0021] Furthermore, the outer wall of the threaded ring 5 is provided with anti-slip texture; by providing anti-slip texture, the friction of the outer wall of the threaded ring 5 can be increased when rotating the threaded ring 5.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled 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, the scope of which is defined by the appended claims and their equivalents.
