The Comfort Layout Technology of Mechanical Handbrake

Abstract

In the current vehicle design, mechanical handbrake is widely used as a low-configuration model and often proposed as cost reduction scheme, and because of its frequent use during the driving and the need to meet the convenience of users of different stature, to make sure the comfort layout of mechanical handbrake is still of great importance in the design process. Based on the actual operation process of the user, this paper decomposes the process into nine comfort variables that users can easily perceive, including the initial position of the handbrake, the pull-up position of the handbrake, the horizontal angle of the initial position, the horizontal angle of the pull-up track of the handbrake, the pull-up stroke of the handbrake, the horizontal angle after the pull-up of the handbrake, the distance between the operating point of the handbrake and the human body in Y direction, the Y inclination angle of the handbrake, and the gap between the centerline of the arm and the hand pillow after the handbrake is pulled. In this paper the comfort variables are discussed based on theoretical human body analysis and large database analysis, then summarized into relative comfort range, after verification on the adjustable physical bench, we finally get a comprehensive recommended range of handbrake layout comfort parameters. The final research conclusion can be effectively uesd to guide the project development, to improve the quality of project development, and to ensure the man–machine comfort of product design.
