[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A device for testing the strength of automotive fabric leather materials comprises a tooling platform, a fixed structure, a weight hook structure, and a data acquisition controller. A height adjustment crossbar is fixed on the tooling platform, the fixed structure is fixed to the tooling platform, the fixed structure comprises a fabric leather material angle adjustment structure, the weight hook structure comprises a fixed ring and a hook, a weight is hung on the hook, an acceleration sensor is provided on the weight, and the fixed ring is fixed to the height adjustment crossbar.

[0006] The fabric leather material angle adjustment structure is provided with a plurality of angle adjustment slots.

[0007] The hook is provided with a hook latch.

[0008] The weight is provided with a hanging ring, and the weight is hung on the hook through the hanging ring.

[0009] The test device of the utility model can simulate dynamic stress and calculate the collision velocity and self-strength of this type of fabric leather by testing the transient acceleration. Moreover, the angle is adjustable and suitable for different extreme working conditions, providing data reference for the selection and research of such products. This simple and rapid verification greatly improves the test efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Reference Figure 1 A device for testing the strength of automotive fabric leather materials includes a tooling platform 1, a fixed structure 2, a weight hook structure 3, and a data acquisition controller 6. A height adjustment crossbar 11 is fixed on the tooling platform 1, the fixed structure 2 is fixed on the tooling platform 1, the fixed structure 2 includes a fabric leather material angle adjustment structure 21, the weight hook structure 4 includes a fixed ring 43 and a hook 42, a weight 5 is hung on the hook 42, an acceleration sensor 52 is provided on the weight 5, and the fixed ring 43 is fixed on the height adjustment crossbar 11.

[0016] like Figure 2 The fabric leather material angle adjustment structure 21 is provided with a plurality of angle adjustment slots 211 , and the heights of the plurality of angle adjustment slots 211 are different, and the fabric leather material can pass through different angle adjustment slots 211 .

[0017] like Figure 3 The hook 42 is provided with a hook latch 41. The hook latch 41 can be a structure commonly used in daily life, such as a key chain. The hook latch 41 is used to latch the hook. When the hook latch 41 is removed, the hook 42 is disengaged and the weight falls off the hook.

[0018] like Figure 4 The weight 5 is provided with a hanging ring 51 , and the weight 5 is hung on the hook 42 through the hanging ring 51 .

[0019] When testing the strength of automobile fabric leather, one end of the fabric leather material 3 is fixed to the fixed structure 2, and the other end is adjusted through the angle adjustment slots 211 of different heights through the fabric leather material angle adjustment structure 21 to adjust the force angle. Generally, the force angle of the extreme working conditions of 10°-40° can be simulated. Finally, the other end is fixed on the weight 5. It is worth mentioning that the weight can be replaced according to different working conditions. The weight is hung with the weight hook structure 4 and the theoretical height is reached through the height adjustment cross bar 11. An acceleration sensor 52 is set on the weight 5, and the other end of the sensor is connected to the digital acquisition controller 6.

[0020] When the automotive fabric leather strength testing device is working, the data acquisition controller 6 is started, then the hook latch 41 is removed, the hook 42 is disengaged, the weight 5 pulls the fabric leather test material 3 to fall freely, and the acceleration sensor 52 collects data. The acceleration curve of the process can be read on the data acquisition controller 6, and key parameters such as the maximum force value and the maximum speed can be calculated through calculation. The data acquisition controller 6 can read and calculate the data using software compiled by existing methods and algorithms.

[0021] The utility model has the following positive effects: (1) it can provide dynamic strength test for various types of fabric and leather materials, and is easy to install and replace; (2) it can simulate the strength under force of 10°~40° according to different test conditions; (3) it can replace different weights to test the strength under different gravity; (4) it calculates the strength of fabric and leather and the maximum test speed by processing the signals collected by the acceleration sensor, which is closer to the real scene than the constant speed test.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein, which should all be included in the scope of protection of the present invention.
