Description

Technical Field

[0001] This utility model relates to the field of automated testing technology, and in particular to a device for testing the stiffness of automobile seats. Background Technology

[0002] Car seats are a key component for ensuring driving safety and must possess sufficient strength and rigidity to prevent breakage and failure under certain impact loads, thereby reducing injury to occupants. Therefore, it is necessary to test the rigidity of car seats.

[0003] In existing technologies, the stiffness of automotive seats is typically measured by fixing the seat in place and evaluating its stiffness by measuring the deformation of the seat under a predetermined pressure. However, existing seat stiffness measuring devices can only apply pressure to a specific location on the seat, and the operation is cumbersome and the testing efficiency is low.

[0004] Therefore, in view of the shortcomings of existing technology, it is necessary to design a car seat stiffness testing device to solve the above problems. Utility Model Content
