Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing fixtures, specifically a tooling for testing the lifespan of an automotive tailgate lifter. Background Technology

[0002] Modern cars are equipped with a trunk at the rear. In the field of car trunk tailgates, there are two ways to open the tailgate: one is manual and the other is electric. Manual opening requires a key or a button inside the car to open when taking out items, which is inconvenient in actual use. Electric opening generally uses a hydraulic rod or electric crank. To ensure product quality, it is necessary to conduct simulated tests on the lifespan of the tailgate lifter, that is, to test the maximum number of times the tailgate lifter can be used when opening and closing the car tailgate. However, the current lifter life test fixture directly applies a load to the lifter to simulate the actual use conditions. But during the use of the car tailgate, the lifter does not only extend and retract, but also rotates when the tailgate is opened. At this time, the load on the lifter is constantly changing. Therefore, the test results of traditional life test fixtures differ greatly from the real situation and cannot obtain true life test results. Based on this, this utility model designs a life testing fixture for automobile tailgate lifting rods to solve the above problems. Utility Model Content

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0019] Please see Figure 1-7This utility model provides a technical solution: a tooling for testing the lifespan of a car tailgate lifter, used to test the lifespan of the lifter 1, including a frame and a tailgate simulator 2; the frame includes a vertical plate 31 and a base plate 32 located at the bottom of the vertical plate 31, with multiple first contour seats 33 at the end of the vertical plate 31 away from the base plate 32, the first contour seats 33 being rotatably connected to the outer tube of the lifter 1; the tailgate simulator 2 is rotatably connected to the end of the vertical plate 31 away from the base plate 32, the rotation axis of the tailgate simulator 2 is parallel to the rotation axis of the outer tube of the lifter 1, and the rotation axis of the tailgate simulator 2 is higher than the rotation axis of the outer tube of the lifter 1, the end of the tailgate simulator 2 away from the vertical plate 31 is inclined downward and has multiple second contour seats 21, the second contour seats 21 being rotatably connected to the push rod of the lifter 1; the weight of the tailgate simulator 2 matches the weight of the real tailgate; A first contouring seat 33 is set on the upright plate 31 to rotatably install the outer tube of the lifting rod 1. The tailgate simulation component 2 is also rotatably installed on the upright plate 31. A second contouring seat 21 is set on the tailgate simulation component 2. The push rod of the lifting rod 1 is rotatably installed on the second contouring seat 21. The rotation axis of the tailgate simulation component 2 is parallel to the rotation axis of the outer tube of the lifting rod 1, and the rotation axis of the tailgate simulation component 2 is higher than the rotation axis of the outer tube of the lifting rod 1, simulating the real assembly structure of the car tailgate. The tailgate simulation component 2 can be pushed to rotate upward by extending the push rod of the lifting rod 1. At the same time, the weight of the tailgate simulation component 2 matches the weight of the real car tailgate, so as to simulate the load of the lifting rod 1 under real working conditions, thereby realizing the life test of the lifting rod 1. In this example, there are two of each of the first contour base 33 and the second contour base 21, which are used to install two lifting rods 1 for testing, thereby truly reproducing the actual working conditions of the lifting rods 1. During the test, the two lifting rods 1 were first installed on this fixture. The outer tube of the lifting rod 1 was rotatably connected to the first contour seat 33, and the push rod of the lifting rod 1 was rotatably connected to the second contour seat 21. Then, the opening and closing process of the tailgate was simulated by extending and retracting the push rod of the lifting rod 1, so as to test the service life of the lifting rod 1. This fixture, through the combination of base plate 32, upright plate 31 and tailgate simulation component 2, forms a simulated environment identical to the actual installation state of the lifting rod 1, and matches the weight of the tailgate simulation component 2 with the weight of the real tailgate, simulating the load of the lifting rod 1 during actual use. This makes the life test results of the lifting rod 1 close to the life under real use conditions. The overall fixture structure is simple and easy to use, and can greatly restore the real use conditions of the lifting rod 1, thus avoiding quality problems in the application of new products in real vehicles.

[0020] Furthermore, a counterweight 22 is detachably installed on the tailgate simulation component 2 to simulate tailgates of different weights; like Figure 3As shown, a counterweight 22 is fixedly installed on the tailgate simulation component 2 by bolts. The counterweight 22 can be replaced according to different products being tested, thereby simulating tailgates of different weights and increasing the applicability of the tooling.

[0021] Furthermore, a buffer mechanism 4 is provided at the end of the base plate 32 away from the upright plate 31. The buffer mechanism 4 is used to contact the tailgate simulation component 2 to absorb the impact force when the tailgate simulation component 2 descends. Specifically, the buffer mechanism 4 includes a spring 41, a contact rod 42, and a spring base 43. The spring base 43 is fixedly mounted on the base plate 32, the spring 41 is fixedly mounted on the spring base 43, and the contact rod 42 passes through the spring 41 and is fixedly connected to the end of the spring 41 away from the spring base 43. like Figure 1-4 As shown, a spring base 43 is provided on the base plate 32, and a spring 41 is fixedly provided on the spring base 43. A contact rod 42 is passed through the spring 41, and the end of the contact rod 42 away from the spring base 43 extends out of the spring 41 and is fixedly connected to the spring 41. When the telescopic rod retracts and the tailgate simulation piece 2 descends, the bottom end of the tailgate simulation piece 2 will first contact the contact rod 42, and then press the contact rod 42 against the spring base 43. At this time, the spring 41 will be compressed. The spring 41 absorbs the impact force of the tailgate simulation piece 2, preventing the tailgate simulation piece 2 from directly hitting the base plate 32, and reducing the impact force of the tailgate simulation piece 2 when it contacts the base plate 32 on the life of the lifting rod 1.

[0022] Furthermore, such as Figure 5 As shown, the automotive tailgate lift rod life test fixture also includes a base 5, a base plate 32 rotatably mounted on the base 5, the rotation axis of the base plate 32 is parallel to the rotation axis of the tailgate simulation component 2, and the base plate 32 is provided with a locking mechanism for fixing the angle of the base plate 32, which can adjust the initial angle of the base plate 32, the upright plate 31 and the tailgate simulation component 2 to simulate the working conditions of the lift rod 1 at different angles of the vehicle. Specifically, a locking mechanism is provided at one end of the base plate 32 where the upright plate 31 is mounted and at the end away from the upright plate 31. The locking mechanism includes an adjusting screw 34 and a screw mounting seat 35. The screw mounting seat 35 is fixedly mounted on the base plate 32, and a threaded hole is opened on the screw mounting seat 35 in a vertical direction. The adjusting screw 34 is threaded into the threaded hole opened in the screw mounting seat 35, and the bottom end of the adjusting screw 34 abuts against the base 5. The rotation axis of the base plate 32 is located between the two adjusting screws 34. like Figure 2As shown, screw mounting seats 35 are installed at both ends of the base plate 32 near the vertical plate 31 and away from the vertical plate 31. Adjusting screws 34 are threaded onto the screw mounting seats 35. The bottom end of the adjusting screws 34 abuts against the base 5, and the rotation axis of the base plate 32 is located between the two adjusting screws 34. When one of the adjusting screws 34 descends on the screw mounting seat 35, this adjusting screw 34 will lift the base plate 32 upward, while the side of the base plate 32 with the other adjusting screw 34 will descend. At this time, it is necessary to raise the other adjusting screw 34 on the screw mounting seat 35 to make room for the rotation of the base plate 32. By having the two adjusting screws 34 abut against the base 5, the angle of the base plate 32 can be adjusted and fixed. In use, rotate both adjusting screws 34 simultaneously to lower one adjusting screw 34 and raise the other adjusting screw 34 at the same time, or first rotate the adjusting screw 34 that needs to be raised to disengage it from the base 5, and then rotate the other adjusting screw 34 to lower it. The bottom ends of both adjusting screws 34 are then fully pressed against the base 5 to complete the angle adjustment of the base plate 32. The base plate 32 can be fixed at any angle within the adjustment range by using two adjusting screws 34 to abut against the base 5. At the same time, it can ensure that the base plate 32 will not wobble during use and can ensure the stability of the base plate 32 after the angle adjustment is completed.

[0023] Furthermore, the base 5 is provided with a pad 51 for contacting the adjusting screw 34, and the pad 51 is provided with a wear-resistant layer 52 at the position where it contacts the adjusting screw 34; like Figure 5 As shown, during the angle adjustment of the base plate 32, the adjusting screw 34 needs to abut against the surface of the base 5. At the same time, the adjusting screw 34 needs to rotate relative to the base 5 during the adjustment process. In order to reduce the wear on the surface of the base 5, a shim 51 is provided on the base 5. The shim 51 is used to contact the adjusting screw 34. At the same time, a wear-resistant layer 52 is provided at the contact position between the shim 51 and the adjusting screw 34 to reduce the wear of the shim 51 during long-term use. Furthermore, multiple columns 53 are fixedly installed on the base 5. The columns 53 are provided with arc grooves along the rotation axis of the base plate 32. The center of the arc grooves coincides with the rotation axis of the base plate 32. The side of the base plate 32 is provided with sliders for sliding cooperation with the arc grooves. When the base plate 32 is adjusted at an angle, the slider on the side of the base plate 32 will slide in the arc groove opened in the column 53. The sliding cooperation between the arc groove and the slider restricts the base plate 32, further improving the stability of the base plate 32. like Figure 5As shown in this example, each of the four corners of the base 5 is provided with a column 53, and each of the four corners of the base plate 32 is provided with a slider. The four sliders slide in a one-to-one correspondence with the arc grooves opened on the four columns 53. The sliders and the grooves cooperate to limit the base plate 32 from the four corners, preventing the edge of the base plate 32 from shaking and further improving the stability of the overall frame during use.

[0024] Furthermore, the second contour seat 21 is adjustable in position on the tailgate simulation component 2 to accommodate different lengths of lifting rod 1, and can be tested for lifting rod 1 of different lengths. Specifically, such as Figure 3 As shown, the second contouring seat 21 is fixed to the tailgate simulation part 2 by bolts, and multiple threaded holes are opened on the tailgate simulation part 2 along its length. The second contouring seat 21 can be fixed to different positions of the tailgate simulation part 2 by bolts, thereby changing the distance between the second contouring seat 21 and the first contouring seat 33, so as to adapt to different lengths of lifting rod 1, and life test of telescopic rods of different lengths can be performed. The bottom plate 32 is provided with a latch 61 at the end away from the upright plate 31, and the tailgate simulator 2 is provided with a lock body 62 at the end away from the upright plate 31 for locking with the latch 61. When the tailgate simulator 2 is lowered to the lowest position, the latch 61 installed on the tailgate simulator 2 will be engaged in the groove opened in the lock body 62. At this time, the latch 61 can be locked in the lock body 62, simulating the locking state of the real tailgate, restoring the use state of the vehicle tailgate to the greatest extent, and further improving the realism of the experimental results.

[0025] Furthermore, the bottom of the base 5 is equipped with casters to facilitate the movement of the entire fixture. Additionally, the bottom of the base 5 is also equipped with feet, which support the fixture on the ground after it is moved to the set position, thus ensuring that the entire fixture will not move during use.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
