AI Technical Summary
When the seal of a car's brake cable is poor, water can easily enter, causing corrosion to internal components. Especially in low-temperature environments, it may freeze, affecting the cable's function. In addition, the volatilization of grease causes parking difficulty and wear, reducing its service life.
The cable assembly consists of an EPB guide column, O-ring, nylon joint, rectangular ring, knurled joint and wire rope. Through threaded connection and sealing design, it achieves front and rear double sealing to prevent moisture from entering.
Effectively prevent moisture from entering in harsh environments, ensure the normal operation of the electronic parking function, avoid corrosion and wear caused by poor sealing, and extend service life.

[0002] A car is a non-track-borne vehicle that is powered by a motor and has four or more wheels. It is primarily used to transport people or goods and perform specialized tasks. Based on factors such as purpose, function, and size, cars can be divided into various types, such as sedans, SUVs, MPVs, sports cars, and pickup trucks.
[0003] With the development of intelligent automobile technology, the brake cable, as an important component in the automobile parking system, plays the role of transmitting force during the parking process. Therefore, the seal between the electronic parking actuator and the cable becomes more important. If the seal is not good and water enters, it will first corrode the internal components. It is also possible that when the temperature is below 0℃, the water will freeze, making the cable unable to pull. Poor sealing will also cause the internal grease to evaporate, which will not only make parking difficult but also cause internal wear and reduce the service life. Therefore, a device is urgently needed to solve the above problems. Utility Model Content
[0004] The purpose of the present utility model is to provide a waterproof component for automobile brakes to solve the problem raised in the above-mentioned background technology that poor sealing causes water to enter, which will first corrode internal components and may also cause the water to freeze when the temperature is below 0°C, resulting in the inability to pull the cable; poor sealing will also cause the internal grease to volatilize, which will not only make parking difficult but also cause internal wear and reduce the service life.

The cable assembly consists of a hose, a steel wire rope, a nylon joint, a rectangular ring and a knurled joint. The cable assembly is connected to the EPB guide column equipped with an O-ring by a threaded connection. The specified torque is achieved, so that the axial end face of the assembled rectangular ring is compressed and the O-ring is radially compressed to ensure that there is a front and rear double seal between the knurled joint and the EPB guide column. When the vehicle is driving in a harsh environment, the influencing factors of water entering from the knurled joint and the nylon joint or from the threaded fit between the knurled joint and the EPB guide column are avoided, thereby realizing the electronic parking function.
[0006] Preferably, the rectangular ring is made of rubber and is annular.
[0007] Preferably, one side of the knurled joint is sleeved on the outside of the nylon joint.
[0008] Preferably, the inner side of the knurled joint squeezes the outer side of the rectangular ring.
[0009] Preferably, the knurled joint is wrapped around the outside of the O-ring.
[0010] Preferably, one side of the steel wire rope passes through the interior of the EPB guide column and is engaged with the EPB.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model discloses an electronic parking brake assembly and a cable assembly arranged on the chassis below the vehicle. The cable assembly is composed of a hose, a steel wire rope, a nylon joint, a rectangular ring and a knurled joint. The cable assembly is connected to an EPB guide column equipped with an O-ring by using a thread. When a specified torque is reached, the axial end face of the assembled rectangular ring is compressed, and the O-ring is radially compressed and fitted, thereby ensuring a front-to-rear double seal between the knurled joint and the EPB guide column. When the vehicle is traveling in a harsh environment, the ingress of water from either the knurled joint and the nylon joint or the threaded fit between the knurled joint and the EPB guide column is avoided, thereby realizing the electronic parking function.
