Adjustable Lock Reaction Mechanism for Car Door Lock Test Equipment

Abstract

The invention discloses an adjustable lock counterforce mechanism for vehicle door lock test equipment, which comprises a fixed plate arranged on one side of an analog latch, wherein the analog latch is fixed on a test bench by an installing seat; the fixed plate is provided with an adjusting screw rod; one end of the adjusting screw rod is connected with an adjusting bolt and the other end of the adjusting screw rod is connected with a jacking part capable of sliding along the adjusting screw rod; the end part of the jacking part jacks the installing seat to produce a lock counterforce; and an elastic part is arranged between the adjusting bolt and the jacking part in the adjusting screw rod. By rotating the adjusting screw rod, the adjustable lock counterforce mechanism for the vehicle door lock test equipment compresses the elastic part, changes the elastic force of the elastic part on the jacking bolt so as to adjust the counterforce required when a lock is locked, and is good in universality and wide in application range.

Description

technical field [0001] The invention relates to a car door lock testing device, in particular to an adjustable lock reaction force mechanism used in the car door lock testing device. Background technique [0002] In modern automobiles, various car door locks have been widely used. As we all know, before the car door locks leave the factory, they must be tested for their durability and maximum load to ensure the quality of the car door locks. The opening and closing is realized by disengaging and hooking the hook and the lock. After the door lock is locked, the lock will have a certain reaction force against the hook. In order to better simulate the actual application environment of the door lock, get an accurate As a result of the test, the door lock test equipment generally installs a reaction force mechanism on one side of the simulated lock buckle. The reaction force of the existing lock reaction force mechanism cannot be adjusted, but the reaction force required by diffe...

[0002] In modern automobiles, various car door locks have been widely used. As we all know, before the car door locks leave the factory, they must be tested for their durability and maximum load to ensure the quality of the car door locks.

In order to better simulate the actual application environment of the door lock, get an accurate As a result of the test, the door lock test equipment generally installs a reaction force mechanism on one side of the simulated lock buckle. The reaction force of the existing lock reaction force mechanism cannot be adjusted, but the reaction force required by different types and types of door locks The force size is also different, which causes the existing lock reaction force mechanism to have the disadvantages of poor versatility and small application range
