Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a positioning device for a parking brake cable assembly. Background Technology

[0002] The parking brake, commonly known as the handbrake (or, in some cases, foot-operated), or the parking gear in an automatic car, primarily functions to prevent the vehicle from rolling away after it has come to a stop. It also provides necessary assistance when starting uphill.

[0003] In current parking brake cable assemblies, the cable needs to be continuously pulled and held during use, which easily causes wear on the cable. However, current parking brake cable assemblies cannot provide auxiliary lubrication for the cable, thus reducing its service life and performance. To address this issue, we propose a locking device for the parking brake cable assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a locking device for a parking brake cable assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A locking device for a parking brake cable assembly includes a cable assembly mechanism. The cable assembly mechanism includes a first locking plate and a second locking plate, which are fastened together by a locking mechanism. A bearing is fixedly embedded in the front of the second locking plate, and a rotating shaft is fixedly embedded in the front of the first locking plate. The rear end of the rotating shaft is fixedly connected to the inner wall of the bearing. An oil reservoir is formed inside the first locking plate, an oil cap is installed on the front of the first locking plate, and a booster pump is installed on the front of the first locking plate.

The mounting mechanism includes a mounting plate, a damping pad is fixedly connected to the bottom surface of the mounting plate, and two mounting holes are formed on the upper surface of the mounting plate.

[0009] In a further embodiment, an observation frame is provided on the front of the first card slot, and the observation frame is located in the middle of the first card slot.

[0010] In a further embodiment, a model mark is fixedly connected to the front of the first card slot.

[0011] In a further embodiment, a fastening piece is snapped onto the upper surface of the protective sleeve, and two fastening holes are formed on the upper surface of the fastening piece.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through its cable assembly mechanism, first locking plate, second locking plate, and traction seat, can move the traction seat by locking the first and second locking plates, thereby moving the brake cable to achieve parking cable braking. Furthermore, through its oil reservoir, booster pump, control valve, and oil supply pipe, the booster pump can be controlled to pressurize the oil reservoir, assisting lubricating oil flow through the oil supply pipe. This facilitates the lubrication of the protective sleeve and brake cable, effectively maintaining the lubrication of the brake cable and ensuring the safe and long-term use of this parking brake cable assembly.
