Problems solved by technology

[0002] At present, the vast majority of automobile parking brake devices are manual parking brake devices. The manual parking brake device has the following shortcomings: 1. The driver needs to manually operate each work, which is cumbersome to operate. 2. When parking on a slope with a large angle, the operation is laborious, parking is difficult, and it is often difficult to obtain a large enough braking force To ensure that the car parks reliably, there are potential safety hazards; 3. Regardless of whether it is flat or slope, the driver is used to pulling the parking brake lever to a larger stroke to ensure that the car can be parked reliably. Under normal circumstances, that is to say, under most conditions of use, the wear and deformation of automobile brake mechanical parts such as brakes and brake cables are increased; 4. The manual brake device has been used for a long time, and the brake cables The steel cable in the vehicle will be deformed and elongated, and the elongation of the steel cable will affect its usability. At the same time, it may be difficult for the device to obtain sufficient braking force, which may cause potential safety hazards; 5. The manual parking brake device has a large operating mechanism, and its Takes up a lot of room space

Embodiment Construction

[0047] Please refer to Fig. 1, Fig. 2 and Fig. 3, an electric parking brake device, including a casing 1, an upper cover 2, a gasket 3, a pulley 4, a card 5, a fixed-side sealing ring 6, a fixed-side plug 7, The fixed side sealing cover 8 , the control circuit assembly 10 , the motor assembly 20 , the reducer assembly 30 , the rotating shaft assembly 40 , the parking brake cable assembly 50 , the tension sensor assembly 60 and the emergency release cable assembly 70 . The integrated design of the parts of the electric parking brake device realizes a high degree of integration. Compared with the scattered structure, this design is easier to realize the proper functions of the electric parking brake device itself, and also improves The reliability and stability of the product are improved, and the device is more convenient for repair and maintenance.

[0048] Please refer to FIG. 2 , the upper cover 2 and the casing 1 are fixed by screws, and a waterproof gasket 3 is placed in t...

Abstract

The electric brake apparatus includes one executing mechanism for braking or brake off; one control module includes one signal acquiring circuit to acquire at least signals of brake switch, engine rotation speed, automobile speed, gear box setting and ignition lock setting, and one control circuit to judge based on the acquired signals and to send command for controlling the executing mechanism; and one emergency release assembly to release the braking state of the brake apparatus in case of self abnormality and incapability of braking. The electric brake apparatus is superior to available manual brake apparatus.
