Description

Technical Field

[0001] The present invention relates to the technical field of automobile safety belt detection, in particular to a safety belt buckle hardness detection device. Background Art

[0002] Seat belts are a guarantee of driver's driving safety. They are active safety measures that can save lives at critical moments. Seat belts are composed of a belt, a buckle, and a plug-in buckle. The plug-in buckle is inserted into the buckle to lock it. The buckle surface is made of plastic material, and the interior is a metal locking structure. The seat belt buckle is used to ensure the safety of people in the vehicle. Therefore, high requirements are placed on its hardness. Hardness testing is required during production. For example, Chinese invention patent with authorization announcement number CN113984877A discloses a vehicle seat belt buckle hardness testing tool, which includes: a workbench; a feeding component; a heating table; a hardness testing component; and a gripping component. Currently, when testing the hardness of the seat belt buckle surface, a Shore hardness tester is often used for testing. This is suitable for testing the hardness of the plastic material on the surface. However, the current seat belt buckle hardness testing device has the following defects:

[0003] When testing the surface hardness of a seat belt buckle, multiple points are selected for testing to ensure the reliability of the test results. This requires multiple adjustments to the seat belt buckle position and multiple clamping, which is particularly inconvenient to use. In addition, the Shore hardness tester needs to press down during testing, which can easily cause vertical deviations, resulting in the pressure point not being vertical enough. In particular, when contacting the seat belt buckle, the pressure path can easily cause slight horizontal deviations, affecting the reliability of the test results.

After completion, the sliding block 47 drives the pneumatic push rod 48 to adjust to the next testing point, and repeats the testing action. If necessary, the carrying component 3 can drive the seat belt buckle to move to the temperature control mechanism 5, and change the seat belt buckle through the thermoelectric cooling plate 53. After the surface temperature of the buckle is measured, the test is carried out again; the adjustment mechanism of the present invention is moved by the sliding block 47 equipped with a pneumatic push rod 48 for pressing down the Shore hardness tester 2, which can be moved in two axes in the horizontal direction, thereby driving the Shore hardness tester 2 to change the horizontal position, and performing hardness tests on the surface of the seat belt buckle at multiple points. In this way, there is no need to change the clamping position of the seat belt buckle, and the hardness test of multiple points can be completed with a single clamping, which is more convenient; the guide component 43 of the present invention can lock the position of the guide sleeve 434 by tooth engagement, so that when the downward test is performed, the guide square column 4328 will be upper-limited in the horizontal direction by the guide sleeve 434, reducing the risk of the downward path of the Shore hardness tester 3 being slightly offset in the horizontal direction when pressing down, thereby ensuring the reliability of the test result.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
