Testing method of vehicle trunk lock dynamic testing machine

Abstract

The invention discloses a testing method of a vehicle trunk lock dynamic testing machine. The method comprises the steps that: a lock body is placed into the machine; the machine is started; a safety door is closed and a sensor works normally; the clock body is clamped tightly; a plug-in unlocking cylinder stretches out to be connected with a lock body joint, and the machine judges whether the lock body is in an unlocking state; the plug-in unlocking cylinder returns to be separated from the lock body joint; an arm lifting cylinder rapidly stretches a swing arm out and falls freely; the plug-in unlocking cylinder stretches out to be connected with the lock body joint; a system checks whether a locking signal is normal; the lock body is unlocked when a constant sealing force is applied; the plug-in unlocking cylinder returns to be separated from the lock body joint; the arm lifting cylinder lifts the swing arm and falls freely; the plug-in unlocking cylinder stretches out to be connected with the lock body joint; the system checks whether the locking signal is normal; a snow loading cylinder is ejected out, and the lock body is powered on and unlocked; the system is automatically unlocked and detects an unlocking signal; and the plug-in unlocking cylinder returns to be separated from the lock body joint. According to the invention, the real vehicle environment is completely simulated, abnormal defects can be totally exposed, and the product quality can be well managed and controlled.

Description

technical field [0001] The invention relates to a testing method of a dynamic testing machine for tail box locks of automobiles. Background technique [0002] The car trunk lock helps the owner to unlock and lock the trunk accurately when opening and closing the trunk. When unlocking, the dead bolt mechanism in the lock body is released under the drive of the unlocking motor, the lock hook is opened, and the tail box is unlocked. At the same time, the switch used to monitor the lock state (open and close) in the lock body is also turned on or off accordingly, telling the car computer that the lock has been opened normally, and vice versa. [0003] At present, the enterprise will have an EOL final inspection and testing machine at the end of the production process of the car trunk lock. It tests the entire function of the product and judges whether it is qualified, and plays a decisive role in the control of product quality. However, it also has shortcomings, complicated o...
