[0010] FIG1 is a schematic diagram of the structure of the utility model. DETAILED DESCRIPTION

[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0012] As shown in FIG1 , the utility model provides a life simulation test platform for a car seat bearing, comprising a test platform 1, wherein the test platform 1 is provided with a pair of mutually parallel guide rails 2, wherein the guide rails 2 are slidably provided with guide rail sliders 3, wherein a moving seat 4 is provided between the pair of guide rails 2, wherein both sides of the moving seat 4 are detachably connected to the corresponding guide rail sliders 3 through connecting pieces 5, wherein both ends of both sides of the moving seat 4 are further provided with mounting shafts 6, wherein the mounting shafts 6 are used to mount a bearing to be tested 7, wherein the bearing to be tested 7 is sleeved on the mounting shafts 6 and can roll along the test platform 1, wherein the test platform 1 is provided with a driving mechanism for reciprocating the moving seat 4 relative to the test platform 1, wherein the moving seat 4 is provided with a plurality of gravity blocks 8, and wherein the test platform 1 is provided with a digital display counter 9 for measuring the number of reciprocating times of the moving seat 4.

[0013] When the utility model is used, the bearing to be tested 7, i.e., the automobile seat bearing, is mounted on the mounting shaft 6 of the moving seat 4, and then the two sides of the moving seat 4 are detachably connected to the corresponding guide rail slider 3 through the connecting piece 5. At this time, the bearing to be tested 7 is placed on the test platform 1, and then a number of gravity blocks 8 are placed on the moving seat 4. The gravity blocks 8 are used to apply gravity to the bearing to be tested 7 to simulate the weight of the user. The number of gravity blocks 8 can be loaded as needed, and then the moving seat 4 is driven to move by the driving mechanism, the guide rail slider 3 slides relative to the guide rail 2, and the bearing to be tested 7 rolls back and forth on the test platform 1, thereby simulating the use scenario of the automobile seat bearing. When the bearing to be tested 7 has abnormal sound or stuck, the digital display counter 9 records the number of times the automobile seat bearing moves back and forth in real time, which is the service life of the automobile seat bearing. When the test is completed, the driving mechanism stops working, the moving seat 4 stops moving, and the moving seat 4 is disassembled from the guide rail slider 3, and the bearing to be tested 7 can be removed from the moving seat 4. The utility model has the advantages of simple and compact structure, convenient operation and low cost.

[0014] Preferably, the moving seat 4 is provided with an electronic scale 10 for measuring the weight of the gravity block 8. The weight loaded on the moving seat 4 can be known by the electronic scale 10, and the operation is simple.

[0015] Preferably, two ends of one of the guide rails 2 are provided with travel switches 11 , and the travel switch 11 is used to control the reciprocating distance of the moving seat 4 .

[0016] Preferably, the driving mechanism includes a driving motor 12, a screw rod 13 and a screw nut, the output end of the driving motor 12 is connected to one end of the screw rod 13, the screw rod 13 is arranged in parallel above one of the guide rails 2, and the screw nut is fitted on the screw rod 13 and fixed on the corresponding guide rail slider 3. The driving motor 12 drives the screw rod 13 to rotate forward, and the screw nut cooperates with the screw rod 13 to convert the rotational motion of the screw rod 13 into the linear motion of the moving seat 4, that is, the moving seat 4 moves forward; the driving motor 12 drives the screw rod 13 to reverse, and the screw nut cooperates with the screw rod 13 to drive the moving seat 4 to move backward, thereby realizing the reciprocating motion of the moving seat 4.

[0017] Preferably, the test platform 1 is provided with a rolling groove 14 for the bearing 7 to be tested to roll, which can achieve better test results.
