[0002] The vehicle slide rail is installed under the seat to adjust the front, rear, left and right position of the seat to make the passengers sit more comfortably. The assembly is usually composed of parts such as the upper slide rail, the lower slide rail, the locking assembly and the unlocking handle. Before the slide rail assembly is put into use, it is necessary to carry out necessary performance tests, such as operability, durability, looseness gap and peeling strength, which must meet the requirements.

[0053] A weight fixture for simulating a vehicle seat 7;

[0054] There are two mounting seats 8, and the two mounting seats 8 are respectively adjustable and installed in the assembly holes of the upper rails 6 of the slide rails on both sides. The two mounting seats 8 are slidably connected to each other, and the counterweight tooling 7 is installed on one mounting seat 8;

[0058] A pulling mechanism 12 is used for testing the peeling strength of the slide rail, and the pulling mechanism 12 is installed on the working frame 10 .

[0059] The method of using the above-mentioned vehicle slide rail performance testing device comprises the following steps:

[0060] S1. Positioning of the slide rail assembly: firstly, place the slide rail assembly to be tested on the test platform 1, and lock and position the two ends of the slide rail lower rail 4 on both sides respectively by means of the manual quick clamp 5;

[0061] S2. Durability test of slide rail assembly: a counterweight fixture 7 with corresponding counterweight is placed on a mounting seat 8 to simulate the actual state of a vehicle seat. After removing the pressure inclined plate 9, the slide rail assembly is subjected to durability test at room temperature through the push-pull mechanism provided on the test platform 1. Under the action of the specified load cycle, after reciprocating for 15,000 times at a frequency of 15 to 20 times / min, check whether it still works normally. If it cannot work normally, it fails the test.

[0062] S3, loosening clearance and peeling strength test of the slide rail assembly: During the S2 process, if the slide rail assembly still works normally, the durability test process is stopped. The test result shows that the slide rail assembly is not damaged. On this basis, the pressure inclined plate 9 is installed, and the loosening clearance and peeling strength test of the slide rail assembly is carried out through the pushing mechanism 11 and the pulling mechanism 12;

[0064] S5. Dismantle the slide rail assembly: Dismantle the slide rail assembly that is damaged during the loose gap and peel strength test process.

[0065] In this embodiment, the pushing mechanism 11 includes:

[0066] A fixing plate 111 mounted on the test platform 1 and the top frame 3;

[0067] A push plate 112 is slidably disposed on the fixed plate 111 via a slide bar 113. A spring 114 is sleeved on the slide bar 113. One end of the spring 114 abuts against the fixed plate 111, and the other end of the spring 114 abuts against the push plate 112. The side end surface of the push plate 112 abuts against the pressure inclined plate 9.

[0068] A driving motor 115, wherein the driving motor 115 is mounted on the top frame 3;

[0069] A crank 116, one end of which is mounted on the output end of the driving motor 115;

[0070] A slider 117, the slider 117 is slidably disposed on the work frame 10, and a rotating seat 118 is rotatably mounted on one side of the slider 117;

[0071] The push rotating ring 119 is detachably mounted on the rotating seat 118 , and the other end of the crank 116 is slidably disposed in the push rotating ring 119 .

[0072] In this embodiment, the pulling mechanism 12 includes:

[0073] The second driving motor 121 is installed on the working frame 10;

[0074] A lead screw 122, one end of which is mounted on the output end of the second driving motor 121, and the other end of which is rotatably connected to the work frame 10, and the lead screw 122 is also threadedly mounted on the slider 117;

[0075] A fixed head 123, the fixed head 123 is fixedly mounted on the pressure inclined plate 9 on one side;

[0076] An open guide groove 124, the open guide groove 124 is rotatably connected to the fixed head 123, and a sliding ball 125 is slidably arranged in the open guide groove 124;

[0077] A telescopic head 126, one end of which is mounted on the pressure-bearing inclined plate 9 on the other side, and the other end of which is telescopically mounted on the open guide groove 124;

[0078] A pull rod 127 , one end of which passes through the open guide groove 124 and is mounted on the sliding ball 125 , and the other end of the pull rod 127 is hinged on the slider 117 .

[0079] In this embodiment, if Figure 1 , Figure 5 As shown, in the test stage of the loosening gap and peeling strength of the slide rail assembly of S3, specifically: the slide rail assembly is installed on the test platform 1, so that the upper rail 6 of the slide rail extends out of the lower rail 4 of the slide rail as little as possible, that is, the upper rail 6 of the slide rail overlaps with the lower rail 4 of the slide rail to the maximum extent and the slide rail is locked by the locking component in the assembly, and the crank 116 is driven to rotate by the output end of the driving motor 115, and the other end of the crank 116 reciprocates in the appropriately selected push rotating ring 119, which will drive the push rotating ring 119 to rotate on the slider 117, and then the side end of the push rotating ring 119 performs an intermittent push action on the push plates 112 on both sides, and under the elastic force of the spring 114 itself, after the push rotating ring 119 is separated from the push action on the push plate 112, the push plate 112 returns to the initial position on the slide rod 113 again;

[0080] Under the reciprocating pushing action, the other side end of the pushing plate 112 will further push the pressure-bearing inclined plate 9, and the pressure-bearing inclined plate 9 will pass through the two mutually sliding mounting seats 8, and this process will not affect the mutual sliding of the two mounting seats 8 because one end of the telescopic head 126 can be telescopically mounted on the open guide groove 124, thereby driving the lower slide rail to deflect intermittently to both sides, and the displacement sensor installed on the test platform 1 detects the degree of deflection of the slide rail upper rail 6 on the slide rail lower rail 4. The reciprocating pushing action is continuous. After a period of time, the deflection degree of the upper rail 6 of the slide rail has no obvious change, and the pressure sensor installed on the push plate 112 can also use a digital push-pull dynamometer to more intuitively record the push load. Although the loose gap test is a destructive test, under the push load of the fixed-size push swivel 119, the side end of the single-side upper rail 6 of the slide rail is in a critical deformation state, that is, the gap on one side is the smallest and the gap on the other side is the largest. In this state, it does not affect the mutual cooperation between the upper rail 6 of the slide rail and the lower rail 4 of the slide rail in the vertical direction;

[0081] The output end of the driving motor 121 drives the lead screw 122 to rotate, driving the slider 117 to move upward on the workbench 10, and then pulling the sliding ball 125 through the pull rod 127, thereby pulling the pressure inclined plate 9 through the open guide groove 124 and the fixed head 123 and the telescopic head 126 on both sides, and then applying a longitudinal tensile stress load to the upper rail 6 of the slide rail below, until the tension sensor installed on the pull rod 127 detects the maximum tension of the upper rail 6 of the slide rail to separate from the lower rail 4 of the slide rail in the vertical direction. At this time, the slide rail assembly is completely destroyed. After the test, the maximum destructive tension is the measured peeling stress. In this test equipment, the corresponding test data can be obtained through a slide rail assembly, thereby reducing the test cost while ensuring the accuracy of the test.

[0082] In this embodiment, if Figure 6 , Figure 7 As shown, the rotation path of the crank 116 is placed between the two push plates 112, and the side end of the push swivel 119 intermittently abuts against the push plates 112 within the rotation path to simulate the intermittent load applied to the slide rail by the combined weight of the driver and passenger's own weight and the weight of the car seat when the car encounters a complex road section during normal driving, thereby more realistically restoring the use environment.

[0083] In this embodiment, if Figure 1 , Figure 5 , Figure 8As shown, a mounting opening 128 is provided on the pressure inclined plate 9, and an open fork frame 129 is installed on each of the two mounting seats 8. The mounting opening 128 and the open fork frame 129 are fixed by bolts. The pulling force required in the peeling strength test stage is controlled by the height of the slider 117. The mounting angle of the pressure inclined plate 9 on the mounting seat 8 is adjusted by bolts, so that when the stress load is applied during the peeling strength test to ensure stability, the pressure inclined plate 9 can always rest against the side end surface of the push plate 112, thereby not affecting the loose clearance test of the slide rail assembly.

[0084] In this embodiment, if Figure 1 , Figure 5 , Figure 8 , Fig. 9 As shown, the open guide groove 124 is an arc structure, and the sliding ball 125 is placed in the middle of the arc structure of the open guide groove 124. The pull rod 127 can directly pull the sliding ball 125 to the middle of the arc of the open guide groove 124, keep the tension load uniform in the middle, and avoid stress deviation on the slide rails on both sides of the lower slide rail assembly. A second installation opening 1210 is opened on the pressure inclined plate 9, and the fixed head 123 and the telescopic head 126 are both adjustable and installed in the second installation opening 1210 by bolts. According to different car seat slide rail assemblies, uniform stress can be dynamically applied, which is more applicable.

[0085] In this embodiment, if Figure 1 , Figure 5 As shown, a counterweight block 13 is detachably placed in the counterweight fixture 7, and the side end of the counterweight block 13 is in contact with the inner wall of the counterweight fixture 7, simulating the actual application state of the slide rail assembly and maintaining the stability of the counterweight block 13 to prevent it from flying out of the counterweight fixture 7 during the test process.

[0086] In this embodiment, if Figure 3 , Figure 4 As shown, the clamping head of the manual quick clamp 5 is pressed into the assembly hole on the lower rail 4 of the slide rail, and the top end of the manual quick clamp 5 is placed below the sliding path of the upper rail 6 of the slide rail, maintaining the positioning stability of the lower rail 4 of the slide rail while avoiding affecting the sliding of the upper rail 6 of the slide rail.

[0087] In this embodiment, if Figure 1 , Figure 2 As shown, the push-pull mechanism includes a cylinder 14 and a push-pull head 15. The cylinder 14 is installed on the work frame 10, and the push-pull head 15 is installed on the output end of the cylinder 14. The push-pull head 15 pulls on the unlocking handle 16 of the slide rail.
