A tailgate self-suction lock detection system

Abstract

The invention proposes a tailgate self-priming lock detection system, including a tailgate self-priming lock, a slow-release detection mechanism, an industrial computer, a door-closing detection mechanism, a screw hole position detection mechanism and a short-circuit detection module, a slow-release detection mechanism, a door-closing detection The mechanism, the screw hole position detection mechanism and the short-circuit detection module are all signal-connected with the industrial computer. The door-closing pawl of the tailgate self-priming lock is fixedly connected with the slow release detection mechanism; the door-closing detection mechanism is fixedly connected with the buckle of the tailgate self-priming lock. The present invention can comprehensively evaluate the performance of each key component of the tailgate self-absorption lock through the combination detection of the slow release detection mechanism, the door closing detection mechanism, the screw hole position detection mechanism and the short circuit detection module, so that the quality of the tailgate self-priming lock is more reliable , has the advantages of high integration and small footprint.

Description

technical field [0001] The invention relates to the field of mechanical automation detection, in particular to a tailgate self-suction lock detection system. Background technique [0002] The self-suction lock of the tailgate of the car can realize the automatic locking and unlocking of the tailgate of the car, and has been widely used in cars. The tailgate lock pulls or pushes the opening lever through the wire drawing or connecting rod, the opening lever moves the pawl, the pawl meshes with the ratchet, the pawl drives the ratchet to rotate to a certain angle, and then the self-priming lock drives the latch and the buckle to lock. Realize the closure of the tailgate. Even when the tailgate is in the semi-locked position, the suction and pull motor of the self-priming lock will also drive the linkage mechanism to turn the latch to close the tailgate. Due to the complex structure of the self-priming lock, there are many quality inspection procedures for the self-priming lo...
