[0002] The handbrake, also known as the parking brake, is an important safety device for automobiles. It is mainly used to secure the vehicle after it has come to a stop and prevent it from moving accidentally. When you need to brake, pull the handle upwards. Before driving, you can press the brake release button. One end of the brake contact button will push the pawl, and then you can press the handle down to return it to its original position and release the brake.

[0003] Everyone's strength is different. When pulling the lever to apply the brakes, if the force is too great, when a person with less strength drives the car, it will be difficult for them to press the lever back to its original position when releasing the brakes. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-4 A handbrake cable assist device includes a brake lever 1 and a pawl 2. A brake release jacking component is fixedly connected inside the brake lever 1. A force-adding rod 3 is slidably sleeved on the outer wall of the brake lever 1, and a cavity 4 is opened inside the force-adding rod 3. A brake release control component is provided inside the cavity 4.

[0017] As can be seen from the above structure: by setting the force-adding rod 3, when in use, the force-adding rod 3 can be pulled, thereby increasing the power arm for moving the brake lever 1, so that the user can press the brake lever 1 with very little effort. At the same time, by setting the brake release control component in the cavity 4 and using it in conjunction with the brake release jacking component, pulling the force-adding rod 3 will not affect the release of the brake. When releasing the brake, the brake release control component can control the brake release jacking component to jack the ratchet 2, thereby completing the brake release.

[0018] Furthermore, the brake release actuation assembly includes a housing 5 disposed on one side of the pawl 2, and the housing 5 is fixedly connected to the inner wall of the brake lever 1. A piston 6 is slidably connected to the inner wall of the housing 5, and a push rod 7 is fixedly connected to one end of the piston 6. One end of the push rod 7 passes through the housing 5 and extends to one side of the pawl 2. By setting the push rod 7 to cooperate with the piston 6, after a medium enters the housing 5, the medium entering the housing 5 can press the piston 6. The moving piston 6 drives the push rod 7, thereby allowing the push rod 7 to push the pawl 2, thus completing the brake release.

[0019] Furthermore, the brake release control assembly includes an elastic sleeve 8 fixedly connected to the inner wall of the cavity 4, and a pressure block 9 is provided on one side of the elastic sleeve 8. A button 10 is fixedly connected to one side wall of the pressure block 9. One end of the button 10 passes through the cavity 4 and extends to the outside of the cavity 4. A flexible tube 11 is connected to one side wall of the cavity 4, and one end of the flexible tube 11 is connected to the housing 5. By setting the button 10, the elastic sleeve 8 and the flexible tube 11 to work together, when the button 10 is pressed, the button 10 can drive the pressure block 9, so that the pressure block 9 presses the elastic sleeve 8, thereby causing the elastic sleeve 8 to press the medium in the cavity 4 into the housing 5, thereby pushing the piston 6 and the push rod 7.

[0020] Furthermore, a strip groove 12 is provided on the outer wall of the brake lever 1, and a limit block 13 is slidably connected to the inner wall of the strip groove 12. The limit block 13 is fixedly connected to the inner wall of the force-applying rod 3. By setting the limit block 13, the force-applying rod 3 can be limited to prevent the force-applying rod 3 from disengaging from the brake lever 1.

[0021] Furthermore, the outer wall of the extension rod 3 is fixedly fitted with a rubber sleeve, and the outer wall of the rubber sleeve is provided with anti-slip texture.

[0022] Furthermore, a return spring 14 is provided inside the brake lever 1, and one end of the return spring 14 is fixedly connected to the force-applying rod 3; by providing the return spring 14, after the force-applying rod 3 is pulled open, the force-applying rod 3 can be released, and the return spring 14 can drive the force-applying rod 3 to automatically return to its original position.
