Description

Technical Field

[0001] This utility model relates to the field of luggage collision testing technology, and in particular to a universal luggage clamp for luggage collision testing. Background Technology

[0002] When conducting crash tests on the rear seat trunk of a car, it is usually necessary to simulate the relative positional relationship between the trunk lid and the seat in a real vehicle, including height and angle parameters. In the early stages of project development, a complete real vehicle body is often unavailable, so a special trunk jig needs to be made to simulate this environment.

[0003] In existing technologies, trunk crash tests for different vehicle models typically require custom-designed clamps based on the trunk data of the specific vehicle model. The disadvantage of this approach is that:

[0004] 1. Each project requires redesigning and manufacturing the fixtures, resulting in wasted material and processing costs;

[0005] 2. The fixture cannot be reused after the test, resulting in idle resources and storage problems;

[0006] 3. The production cycle is long, which affects the progress of the experiment;

[0007] 4. Unable to quickly adapt to parameter changes in different vehicle models.

[0008] Therefore, there is an urgent need for a universal luggage clamp that can adapt to various vehicle parameters and is reusable, in order to reduce testing costs and improve testing efficiency. Utility Model Content

[0011] A universal luggage clamp for luggage collision testing includes a fixed base, an extension rod, and a luggage block support plate. The fixed base includes a base plate and a vertical rod fixed on the base plate. The extension rod is a lead screw structure, sleeved inside the vertical rod, and can move up and down relative to the vertical rod. The luggage block support plate is connected to the top of the extension rod through an angle adjustment mechanism, and can rotate to adjust the angle relative to the extension rod. The angle adjustment mechanism includes a first through-hole block fixed to the top of the extension rod and a second through-hole block fixed to the lower part of the luggage block support plate. The luggage block support plate is connected to the first through-hole block and the second through-hole block by connecting bolts passing through the first through-hole block.

[0012] Preferably, the second through-hole block is provided with a strip groove.

[0013] Preferably, the extension rod is provided with a rotating component for rotating and raising / lowering the extension rod.

[0014] Preferably, the substrate has a plurality of fixing holes for connecting the slide.
