Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic parking brake technology, and in particular to a connector structure for an electronic parking brake. Background Technology
[0002] With the continuous development of automotive technology, electronic parking brakes (EPB) have gradually replaced integrated mechanical brakes (IPB) and are widely used in various vehicle models. EPB and IPB share similar braking principles: both generate braking force by pushing out friction pads and causing them to rub against the brake disc. The difference lies in the braking mechanism: when parking, IPB uses a mechanical handbrake to push out the friction pads for continuous braking force, while EPB maintains braking force through an electronic parking actuator integrated into the brake. Electronic parking actuators mostly use an electric motor as a power source, converting the motor's rotation into braking force on the brake disc through gear transmission. However, in existing technology, the housing connectors of electronic parking actuators are basically fixed structures of a single size, which cannot meet the needs of varying actuator connector positions. Utility Model Content
