Device for simulating load capacity of door lock during closing of sliding door of automobile

Abstract

The invention relates to a device for simulating load capacity of a door lock during the closing of a sliding door of an automobile. The invention is characterized in that the device comprises a base plate, fixed installing plates and a door lock installing plate, wherein the fixed installing plates are vertically arranged on the base plate at intervals and are provided with a transverse linear guide rail and a power source which drives a load installing plate to move along the linear guide rail; a transverse guide rail is fixed on the load installing plate; a sliding block is arranged on theguide rail; a load spring is connected between the load installing plate and the sliding block; a lock column installing plate is also fixed at the outer side of the sliding block; a lock column is arranged on the lock column installing plate; and the door lock corresponding to the lock column is arranged on the door lock installing plate. With the adoption of the simulating device, as the durability test of the door lock can be transferred from an automobile body to a laboratory table, the cost is saved, the test steps are simplified, and the period of product development is shortened.

Description

technical field [0001] The invention relates to a simulation device, in particular to a device for simulating the load force of a door lock when a sliding door of an automobile is closed. Background technique [0002] With the rapid development of the domestic automobile industry, the share of MPVs in the domestic market is increasing year by year, and MPVs are generally equipped with single or double sliding doors. In addition, electric sliding doors are becoming more and more popular. [0003] The existing electric sliding door structure has a sealing strip on the door, and when the electric sliding door is closing the door, when the sealing strip touches the vehicle body, the sealing strip will be subjected to a reverse elastic force, and the lock cylinder will generate a pulling force on the door lock ratchet. Existing durability tests on the sealing strip to close the door elastically pull the door lock are all done directly on the vehicle body, which causes many inconv...

AI Technical Summary

Problems solved by technology

Existing durability tests on the sealing strip to close the door elastically pull the door lock are all done directly on the vehicle body, which causes many inconveniences:

[0004] 1. The price of the body during the test is relatively expensive, and the corresponding body of various door locks is not the same, so it is inconvenient to purchase and the cost is also high

[0005] 2. The car body itself has a relatively large space, and the door lock environment test and other requirements require simulation functions. This test requires a relatively large space and requires relatively high site requirements.

[0006] 3. The structure of the electric sliding door is relatively complicated, and the structures of various doors and door locks are different. It is cumbersome to assemble the entire door lock system on the door, and it is not convenient to disassemble and adjust the door lock, so the test cost is reduced. efficiency, greatly increasing the labor force of the testers

[0007] Therefore, the traditional electric sliding door durability test system is not only costly and complex to use, but also time-consuming, taking up a lot of labor and money
