Embodiment Construction

[0021] The automobile seat strength test method of the single hydraulic cylinder effect of the present invention is realized in the following way, see figure 2 As shown, the test method for the strength of a car seat with a single hydraulic cylinder includes four parts: seat installation, hydraulic cylinder loading, angle position adjustment, and car seat test. The car seat test part includes the car seat headrest test. , car seat back test, and car seat cushion test. The three test contents mentioned above are all loaded through the same loading hydraulic cylinder.

[0022] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are intended to illustrate the present invention and not limit the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to specific tests.

[0023] In the automobile seat strength test method of the single hydrauli...

Abstract

The invention discloses an automobile seat strength testing method with a single hydraulic cylinder to act, and belongs to the field of tests for the strength of an automobile seat. The testing method comprises the steps of installation of a seat to be tested, loading of the hydraulic cylinder, regulation of angles and positions, and testing of the automobile seat. The testing method is characterized in that the same loading hydraulic cylinder is used for testing a headrest, a backrest and a seat cushion of the automobile seat, and the loading hydraulic cylinder can adjust the loaded height and the loaded angle of the automobile seat. In the testing process, the loading device does not need to shift and change longitudinally, and only the angle and the height need to be adjusted. The automobile seat strength testing method with the single hydraulic cylinder to act has the technical advantages that tests are loaded through the hydraulic cylinder, a loading source is simplified, the whole loading process is safer and more reliable, and the repeatability of test data is high.

Description

technical field [0001] The invention relates to a method for testing the strength of an automobile seat under the action of a single hydraulic cylinder, belonging to the field of strength testing of the automobile seat. Background technique [0002] Car seats are an important part of car interiors. In addition to comfort, car seats also play a safety protection function for the occupants. Many laws and regulations have been issued at home and abroad to regulate the strength and test methods of car seats. Scholars from various countries have also made test methods and equipment for car seat strength. Extensive research such as: [0003] US Patent US5641917 discloses a multi-axis seat fatigue testing machine; [0004] US patent US6386054 discloses a seat test method that simulates a human seat; [0005] U.S. Patent No. 5,373,749 discloses a testing device for a car seat headrest; [0006] US patent US5379646 discloses a robot-loaded seat back test device; [0007] U.S. Pa...
