A testing machine for the durability performance of a car seat height adjuster
A technology of car seats and high-profile devices, which is applied to the testing of machines/structural components, instruments, and measuring devices. It can solve the problem of single-directional loading, the inability to accurately evaluate the quality of the seat, and the inability to accurately simulate the impact of external loads on the seat. And other problems, to achieve the effect of good stability, good softness and low noise

specific Embodiment approach 1
[0020] Specific implementation mode one: combine Figure 1 to Figure 3 Describe this embodiment in detail. A car seat high-profile device durability tester described in this embodiment includes a platform 1, a dummy load 2, an adjustment frame 3, a swing arm mechanism 4, and a two-way drive cylinder 5;
[0021] The platform 1 is set horizontally, the car seat 8 equipped with the height controller to be tested is set on the platform 1, the dummy load 2 is fixed on the car seat 8, the adjustment frame 3 is used to adjust the position of the rotation shaft 9 of the height controller, and the swing arm mechanism 4 includes a fixed part 4-1, a movable part 4-2 and a connecting shaft 4-3, the high-profile device rotating shaft 9 is coaxial with the connecting shaft 4-3 of the swing arm mechanism 4, and the fixed part 4-1 and the movable part 4-2 pass through The connecting shaft 4-3 is connected, the fixed part 4-1 is fixed on the adjustment frame 3; the top end of the two-way drivi...
specific Embodiment approach 2
[0023] Specific embodiment 2: This embodiment is a further description of a car seat high-profile device durability performance testing machine described in specific embodiment 1. In this embodiment, the adjustment frame 3 includes Z-direction brackets 3-1, X to the support 3-2 and the Y-direction support 3-3;
[0024] The Z-direction support 3-1 is vertically arranged on the tooling plate 2-1 of the dummy load 2 along the z-direction, the X-direction support 3-2 is vertically fixed on the Z-direction support 3-1 along the x-direction, and the Y-direction support 3-3 It is vertically fixed on the X-direction support 3-2 along the y direction; the fixed part 4-1 is fixed on the Y-direction support 3-3, and the top of the bidirectional drive cylinder 5 is fixed on the Y-direction support 3-3.
[0025] By adjusting the positions of the three brackets, the position of the rotating shaft 9 of the high-profile device can be adjusted. The device in this embodiment is convenient to ad...
specific Embodiment approach 3
[0026] Specific embodiment three: This embodiment is a further description of a car seat high-profile device durability performance testing machine described in specific embodiment two. In this embodiment, the Z-direction bracket 3-1 and the X-direction bracket 3- 2 and the Y-direction bracket 3-3 are provided with a groove channel, by sliding on the groove channel to adjust the position of the bracket, the clamp block 3-4 is used to realize the Z-direction bracket 3-1 and the X-direction bracket 3-2, X Fix between the bracket 3-2 and the Y bracket 3-3.
[0027] The position of the bracket is adjusted by sliding continuously on the groove channel, which improves the accuracy of the adjustment.
