Abstract

The invention relates to a vehicle front cover locking force measuring device and a vehicle front cover locking force measuring method. The method for measuring the locking force of the front cover of an automobile is characterized in that it includes the following steps: a fixing step of placing the lock cylinder of the front cover of the automobile in the box structure tooling and fixing the box structure tooling to the vehicle body; The two sides of the structural tool form the deformation beam forming step of two deformation beams; the strain gage setting step of pasting a plurality of strain gauges on the deformation beam; the electric bridge forming step of electrically connecting the plurality of strain gauges to form an electric bridge ; The pressure measurement step of obtaining the force received by the front lock of the automobile by measuring the output voltage of the electric bridge. By using the vehicle front cover locking force measuring device and the automobile front cover locking force measuring method of the present invention, the pressure on the front cover lock can be accurately measured without destroying the original vehicle structure.

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...
