Description

technical field [0001] The invention relates to the technical field of motor vehicle accessories, in particular to a hand brake lever assembly. Background technique [0002] The handbrake lever assembly is the main control device when the motor vehicle is parked and braked. As an important working part of the motor vehicle, the working performance of the handbrake lever assembly has also attracted widespread attention. [0003] In the current assembly structure of the handbrake lever assembly, it usually directly connects the handbrake handle with the vehicle brake assembly through the brake cable. Although this structure can meet the basic parking brake requirements, due to The brake cable does not have any protection or guiding structure, which makes the parking cable easy to deform after long-term frequent use, which will not only cause the parking stroke of the handbrake lever assembly to become longer, the parking brake force will decrease, and will also make the handbr...

[0003] In the current assembly structure of the handbrake lever assembly, it usually directly connects the handbrake handle with the vehicle brake assembly through the brake cable. Although this structure can meet the basic parking brake requirements, due to The brake cable does not have any protection or guiding structure, which makes the parking cable easy to deform after long-term frequent use, which will not only cause the parking stroke of the handbrake lever assembly to become longer, the parking brake force will decrease, and will also make the handbrake lever The overall service life of the assembly is correspondingly shortened, and the operating tension at the handbrake lever during the parking operation is not uniform, causing inconvenience to the user's daily operation
