Verification device for automobile trunk assembly operation performance

Abstract

The invention relates to a verification device for the automobile trunk assembly operation performance. The device comprises a base part and an operation part arranged on the base part and movably connected with the base part. A rotating mechanism capable of adjusting the rotating direction of the base part is arranged on the base part, the operation part comprises an aluminum alloy steel frame mechanism for simulating opening / closing of the contact region of a trunk, a mechanism bearing part for installing the aluminum alloy steel frame mechanism on the base part, and a trunk lock bearing part for installing a trunk lock, the trunk lock is installed on the aluminum alloy steel frame mechanism, a lock catch for achieving pinching with the trunk lock is arranged on the trunk lock bearing part, a balance weight mechanism for adjusting the position of the gravity center is arranged on the aluminum alloy steel frame mechanism, and a handle is arranged at the front end of the aluminum alloysteel frame mechanism. Compared with the prior art, the verification device has the advantages of being convenient to use, applicable to different automobile type sizes and the like.

Description

technical field [0001] The invention relates to the design field of automobile operation performance equipment, in particular to a verification device for the operation performance of the automobile trunk assembly. Background technique [0002] The composition of existing automobile trunk assembly is as follows: figure 1 As shown, it includes a hinge 100, a torsion bar 101, a trunk, a buffer block 102, and a trunk lock 105, wherein the trunk has a contact area 106 dedicated to opening / closing the trunk, the position of the center of gravity of the trunk assembly, opening / closing The position of the contact area of ​​the closed trunk, the position of the lock, the position of the buffer block, the distance of the left / right hinge in the Y direction of the body, etc. will affect the operational performance of the trunk (such as the size of the opening / closing force, the minimum closing speed, turn on balance angle, etc.). In the early development process of the project under...

AI Technical Summary

Problems solved by technology

In the early development process of the project under the existing technology, in order to form a better maneuverability of the trunk assembly, the position of the center of gravity of the trunk assembly, the position of the contact area for opening / closing the trunk, the position of the lock, and the buffer block The determination of the position of the left / right hinge in the Y direction of the vehicle body, etc. is based on simple theoretical calculations and historical project experience. However, due to some inaccuracies in theoretical calculations and historical project experience, it is difficult to determine in the early stage of the project. Form a more intuitive and reliable evaluation on the maneuverability of the trunk assembly

Only after the project is mass-produced and the real parts assembly is obtained can the operability be evaluated intuitively and reliably. At this time, if the operability evaluation effect is not satisfactory, a certain degree of design of the trunk assembly is required. It will be very difficult to optimize, because the parts have already been mass-produced
