Automobile trunk lock dynamic testing machine

Abstract

The invention discloses a vehicle trunk lock dynamic testing machine. The vehicle trunk lock dynamic testing machine comprises a trunk cover mechanism arranged on an operation bench, a lock fixing mechanism connected to the trunk cover mechanism, a latch arranged below the lock fixing mechanism, a snow loading mechanism arranged at one open side of the trunk cover mechanism, and a downward-insertion cylinder arranged at one closing side of the trunk cover mechanism. A piston rod of the downward-insertion cylinder is connected with a wedge. The lock fixing mechanism is provided with a lock circuit monitoring unit. The snow loading mechanism comprises at least one group of snow loading cylinders. The snow loading cylinders are horizontal and face the trunk cover mechanism, and two sides of each snow loading cylinder are fixed to the operation bench through cylinder installation plates. When the snow loading mechanism is activated, the piston rods of the snow loading cylinders extend out to be abutted against a push block on the lock fixing mechanism, and in this way, the snow loading situation of the trunk cover mechanism is simulated. 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 dynamic testing machine for an automobile tail box lock. 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 operation, poor compati...
