Vibration test device for automobile door cover lock parts

Abstract

The invention discloses a vibration test device for automobile door cover lock parts, which belongs to the technical field of test devices, and consists of a load simulation mechanism, a lock body fixing mechanism, a lock ring fixing mechanism and a basic mechanism; the load simulation mechanism is fixed at the top end of the basic mechanism, and the lower part of the load simulation mechanism isconnected with the lock body fixing mechanism; the load simulation mechanism provides internal force by compressing a spiral spring, the internal force stabilization effect is guaranteed through a guide screw structure, the internal force is transmitted to the lock body fixing mechanism under the action of a guide screw, and simulation and adjustment of load / separation force between a lock and a lock ring are achieved. The lock body fixing mechanism is in floating connection with the load simulation mechanism, the angle of the lock body mounting surface can be adjusted, and the load applied bythe load simulation mechanism is transmitted to the lock body fixing mechanism and the lock body. The device overcomes the defects of the original scheme, achieves universalization, is suitable for all doors and front and rear cover lock parts of the whole vehicle, does not need to independently design and trial-manufacture each vehicle and each part, and directly reduces the design trial-manufacture period of a single vehicle type by 4 weeks.

Description

technical field [0001] The invention belongs to the technical field of test devices, and in particular relates to a vibration test device for automobile door cover lock components. Background technique [0002] Automobile door lock components include side door locks, hood locks, trunk lid locks, back door locks, etc. The locks cooperate with the lock rings and are important components for keeping the doors and covers closed. In order to ensure quality, the performance and quality of lock components need to be verified by laboratory bench tests, among which vibration test is a very important one, to check whether the lock is damaged after the vibration test and whether it has the function of locking and maintaining. [0003] The installation angle of the lock in different parts and the force between the lock and the lock ring are different. For the lock at the same position, the installation size, angle and force of different models will also be different. The previous schem...

Problems solved by technology

[0005] Aiming at the problems that the vibration test device for door cover lock parts in the prior art cannot be generalized and the boundary simulation is not good, the present invention provides a vibration test device for automobile door cover lock parts; The design and improvement of the original scheme overcome the shortcomings of the original scheme and realize generalization. It is applicable to all door and front and rear cover lock parts of the whole car. It does not need to be designed and trial-manufactured separately for each car and each piece, which directly reduces the design and trial-manufacture cycle of a single model4 Week (calculated according to 4 kinds of locks for each model)
