Abstract

This invention relates to a locking force measurement method and a locking force measurement device for an automobile front cover. The locking force measurement method for the automobile front cover comprises steps of putting an automobile front cover key cylinder in a box structure tooling which is fixed with the automobile body, forming the two sides of the box structure tooling into two deformable beams, adhering a plurality of strain gauges on the deformable beams, forming an electric bridge through electrically connecting the plurality of strain gauges, and obtaining the received force on the automobile front lock by measuring the voltage outputted by the electrical bridge. By utilizing the locking force measurement method and the locking force measurement device for the automobile front cover, the pressure applied on the front cover lock can be accurately measured without destroying the conventional structure of the automobile.

Description

technical field [0001] The invention relates to a measuring method for measuring the force received by a car front cover lock and a measuring device for measuring the car front cover lock. Background technique [0002] When the front cover of the car is closed, the front cover lock will receive a greater impact. Measuring the magnitude of this force will aid in the design of the lock and its surrounding sheet metal. The method mainly includes specific tooling and strain gauge arrangement. [0003] At present, the domestic methods for measuring the locking force of the front cover of the car all need to partially destroy the sheet metal structure of the car body, and measure it by installing a general-purpose force sensor or directly pasting strain gauges on the car body. These methods change the structure of the original body, and greatly change its stiffness, strength and other states, making the measurement results inaccurate. Contents of the invention [0004] In vie...
