Technical Field
[0001] The utility model belongs to the technical field of testing devices, in particular to a durability testing device for an automobile door cover. Background Art
[0002] In the automotive manufacturing industry, the durability and reliability of car door covers are one of the important indicators for measuring car quality. The car door cover durability test includes the door handle durability test, the door opening and closing durability test, the hinge and limiter durability test, and the vibration and impact durability test. During the door handle durability test, the test device repeatedly opens and closes the door and records the number of times the door handle is opened and closed, the force required, and any possible failures or damage, so as to comprehensively evaluate the durability and reliability of the door handle.
[0003] The traditional door handle durability test method is to tie the door handle with a rope, and then collect data after repeatedly opening and closing the door by pulling it with a robot to test the durability of the door handle in the car door cover durability. However, due to the different hand sizes, gripping habits and force distribution of different users, the door handle will be subjected to forces from different directions and magnitudes in actual use. Therefore, it is difficult to accurately reflect the durability performance of the door handle through only a single-position binding test.
[0004] Therefore, in order to solve the above problems, an automobile door cover durability testing device is proposed. Utility Model Content
[0005] In order to make up for the shortcomings of the existing technology and solve the problem that the traditional testing method of using a rope to tie a door handle in a single position is different, due to the different positions of different people holding the door handle, the door handle is subjected to different force distribution and magnitude during long-term use, which limits the accuracy of the test, a car door cover durability testing device is proposed.

Since different people hold the door handle in different positions, the door handle is subjected to different force distribution and magnitude during long-term use, which limits the accuracy of the test. By simulating the hand spacing in various holding scenarios, it ensures that the test can be closer to actual usage, thereby improving the accuracy and reliability of the test.
[0008] Preferably, fixed blocks are fixedly connected on both sides of the limit block, and a first tension spring is provided between the fixed block and the movable block; this avoids the traditional testing method of using a rope to tie a door handle in a single position, which requires the operator to manually tie the rope, which is more troublesome. This reduces manual intervention and improves the convenience of testing.
[0009] Preferably, the moving block is fixedly connected to a sliding rod at one end close to the connecting block, the sliding rod is embedded in the inner wall of the connecting block, the sliding rod and the connecting block are slidingly connected, and the sliding rod is fixedly sleeved at one end close to the connecting block with a limiting ring for limiting the sliding rod from detaching from the inner wall of the connecting block; this avoids the problem of the two limiting blocks being stuck with the door handle due to excessive torsion angle, thereby improving the reliability of the device.
[0010] Preferably, the movable block and the connecting block are connected by a second tension spring, which is placed on one side of the sliding rod; this improves the adaptability of the device, and when the distance between the limit blocks is large, the door handle is closed, and the second tension spring rebounds to restore the state of separation between the movable block and the connecting block.
[0011] Preferably, the cross section of the limit block away from the door handle is set as an inclined surface, thereby ensuring the normal operation of the device.
[0012] Preferably, a latex pad is fixedly connected to the side of the limit block close to the door handle, so that the test can be closer to actual usage, thereby improving the accuracy and reliability of the test and reducing the mechanical wear of the limit block.
[0013] Beneficial effects of the utility model:
[0014] The utility model provides a vehicle door cover durability testing device. By setting an adjustment component, when testing the durability of a door handle in a vehicle door cover durability test, the rotation of a motor is used to drive the movement of two rack plates, thereby adjusting the distance between the two limit blocks, thereby avoiding the traditional testing method of using a rope to tie a door handle at a single position. Since different people hold the door handle in different positions, the force distribution and magnitude to which the door handle is subjected in long-term use are different, which limits the accuracy of the test. By simulating the hand distances under various holding scenarios, it is ensured that the test can be closer to the actual usage, thereby improving the accuracy and reliability of the test.
[0015] The utility model provides a vehicle door cover durability testing device, which has a first tension spring, and when a door handle durability test is conducted on a vehicle door cover, the door handle is restricted and fixed, the protective shell moves forward to drive the limit block to move forward, and when the limit block contacts the door handle, the upper and lower limit blocks are driven by the stretching and rebound of the first tension spring to limit the door handle between the limit block and the protective shell, thereby avoiding the traditional testing method of using a rope to tie the door handle in a single position, which requires the operator to manually tie the rope, which is quite troublesome, thereby reducing manual intervention and improving the convenience of testing.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Specific examples are given below.
[0026] See also Figure 1-Figure 5 The utility model provides a vehicle door cover durability test device, including a test vehicle 1 and a test device body 2, wherein the test vehicle 1 is arranged in the middle of the test device body 2, and door handles 4 are arranged on both sides of the test vehicle 1, a test robot 3 is arranged above the test device body 2, and a protective shell 5 is arranged on one side of the test robot 3, and two moving blocks 10 are slidably connected to one side of the protective shell 5, and the two moving blocks 10 are symmetrically arranged up and down, and the inner wall of the moving block 10 is slidably connected to a limit block 11, and an adjustment component for adjusting the distance between the two limit blocks 11 is arranged inside the protective shell 5;
[0027] The adjustment component includes a motor 6 fixedly connected to the inner wall of the protective shell 5, and a gear 7 is fixedly sleeved on one end of the output shaft of the motor 6. The upper and lower sides of the gear 7 are meshed with rack plates 8, and one side of the two rack plates 8 is fixedly connected to a connecting block 9. The connecting block 9 is arranged at one end of the moving block 10. The test robot 3 records the number of times the door handle 4 is opened and closed through a built-in counter or sensor, and detects and records the force or torque value required during the door opening and closing process in real time through a force sensor or torque sensor. Any possible faults or damage are recorded through a visual detection system, a physical sensor or a comprehensive diagnostic system. The counter, sensor, quantity sensor, torque sensor, visual detection system, physical sensor and comprehensive diagnostic system are all existing technologies, so their internal structure, principle and circuit connection relationship are not described one by one.
[0028] During operation, through the provided adjustment component, when testing the durability of the door handle 4 in the durability test of the automobile door cover, the rotation of the motor 6 is used to drive the two rack plates 8 to move, and then adjust the distance between the two limit blocks 11, avoiding the traditional testing method of using a rope to tie the door handle 4 in a single position. Since different people hold the door handle 4 in different positions, the force distribution and magnitude that the door handle 4 is subjected to are different in long-term use, which limits the accuracy of the test. By simulating the hand distances in various holding scenarios, it is ensured that the test can be closer to actual usage, thereby improving the accuracy and reliability of the test.
[0029] Further, such as Figure 2 and Figure 3 As shown, fixed blocks 12 are fixedly connected to both sides of the limiting block 11 , and a first tension spring 13 is provided between the fixed block 12 and the movable block 10 .
[0030] During operation, through the set first tension spring 13, in the durability test of the door handle 4 in the automobile door cover durability test, when the door handle 4 is restricted and fixed, the protective shell 5 moves forward to drive the limit block 11 to move forward. When the limit block 11 contacts the door handle 4, the upper and lower limit blocks 11 are driven by the stretching and rebound of the first tension spring 13 to limit the door handle 4 between the limit block 11 and the protective shell 5, avoiding the traditional test method of using a rope to tie the door handle 4 in a single position, which requires the operator to manually tie the rope, which is more troublesome. It reduces manual intervention and improves the convenience of testing.
[0031] Further, such as Figure 2 and Figure 3 As shown, the end of the moving block 10 close to the connecting block 9 is fixedly connected to a sliding rod 15, the sliding rod 15 is embedded in the inner wall of the connecting block 9, the sliding rod 15 and the connecting block 9 are slidingly connected, and the end of the sliding rod 15 close to the connecting block 9 is fixedly sleeved with a limiting ring 16 for limiting the sliding rod 15 from detaching from the inner wall of the connecting block 9.
[0032] During operation, by setting the sliding rod 15, in the durability test of the door handle 4 in the durability test of the automobile door cover, when the distance between the two limit blocks 11 is large, the car door is opened, and the door handle 4 presses one of the limit blocks 11. During the process of the protective shell 5 moving backward, the sliding rod 15 drives the limit ring 16 to slide in the connecting block 9, and stretches the second tension spring 14 to separate the moving block 10 from the connecting block 9, avoiding the problem of the two limit blocks 11 and the door handle 4 being stuck due to the twisting angle being too large, thereby improving the reliability of the device.
[0033] Further, such as Figure 2 and Figure 3As shown, the moving block 10 is connected to the connecting block 9 via a second tension spring 14 , and the second tension spring 14 is placed on one side of the sliding rod 15 .
[0034] During operation, by setting the second tension spring 14, in the durability test of the door handle 4 in the automobile door cover durability test, the door handle 4 is limited between the upper and lower limit blocks 11 and the protective shell 5. The stretching of the second tension spring 14 can adapt to door handles 4 of different widths, thereby improving the adaptability of the device. At the same time, when the distance between the limit blocks 11 is large, the door handle 4 is closed, and the second tension spring 14 rebounds to restore the state of separation of the moving block 10 and the connecting block 9.
[0035] Further, such as Figure 4 and Figure 5 As shown, the cross section of the limiting block 11 away from the door handle 4 is set to be an inclined surface.
[0036] During operation, in the durability test of the door handle 4 in the durability test of the automobile door cover, when the door handle 4 is restricted and fixed, the protective shell 5 moves forward, and the inclined surface can smoothly make the door handle 4 and the limit block 11 contact. The door handle 4 presses the limit block 11 to move the limit block 11 upward, and the first tension spring 13 rebounds to pull the upper and lower limit blocks 11 to limit the door handle 4 between the limit block 11 and the protective shell 5, ensuring the normal operation of the device.
[0037] Further, such as Figure 4 and Figure 5 As shown, a latex pad 17 is fixedly connected to the side of the limiting block 11 close to the door handle 4 .
[0038] During operation, through the latex pad 17 that is set, when testing the durability of the door handle 4 in the durability test of the automobile door cover, the latex pad 17 has moderate softness and elasticity, which can simulate the touch of the human hand and simulate the dispersion of the pressure points of the human hand, so that the test can be closer to the actual usage, thereby improving the accuracy and reliability of the test and reducing the mechanical wear of the limit block 11.
[0039] Working principle:
[0040] The automobile door cover durability testing device is used when the durability of the door handle 4 needs to be tested;
[0041] Step 1: Move the test vehicle 1 to the middle position of the test device body 2, control the test robot 3 to move the protective shell 5 to the front of the door handle 4, control the protective shell 5 to move forward, and the protective shell 5 moves forward to drive the limit block 11 to move forward. When the limit block 11 contacts the door handle 4, the limit block 11 is lifted up by the door handle 4 through the inclined surface. The limit block 11 is lifted up, and the limit block 11 drives the fixed block 12 to move upward. The fixed block 12 moves upward and stretches the first tension spring 13. When the limit block 11 exceeds the door handle 4, the first tension spring 13 rebounds and pulls the fixed block 12 downward. The fixed block 12 moves downward, driving the limit block 11 to move downward, and the door handle 4 is limited between the limit block 11 and the protective shell 5 by the upper and lower limit blocks 11.
[0042] Step 2: Start the test robot 3, control the test robot 3 to drive the protective shell 5 to move, the protective shell 5 then drives the limit block 11 to move, the limit block 11 moves and drives the door handle 4 to move and open the door. Similarly, control the test robot 3 to drive the door handle 4 to move, and then close the door. At this time, the motor 6 is energized, and the rotation of the motor 6 drives the gear 7 to rotate. The rotation of the gear 7 engages with the rack on the rack plate 8, driving the two rack plates 8 to move to both sides. The movement of the rack plate 8 drives the second tension spring 14 to move. The movement of the second tension spring 14 drives the moving block 10 to move. The movement of the moving block 10 then drives the limit block 11 to move to both sides. Control the test robot 3 to drive the protective shell 5 to move, the protective shell 5 then drives the limit block 11 to move. The limit block 11 moves and drives the door handle 4 to move and open the door. Similarly, control the test robot 3 to drive the door handle 4 moves, and then the car door is closed. And so on. When the distance between the two limit blocks 11 is large, in the process of opening the car door, the torsion angle of the two limit blocks 11 is large, and the car door handle 4 presses one of the limit blocks 11. In the process of the protective shell 5 moving backward, the sliding rod 15 drives the limit ring 16 to slide in the connecting block 9 and stretches the second tension spring 14 to separate the moving block 10 from the connecting block 9 to ensure the opening of the car door. After closing the car door, the second tension spring 14 rebounds and drives the sliding rod 15 back to its original position. When the motor 6 rotates to the set number of circles, the motor 6 starts to reverse. The motor 6 reverses and drives the two rack plates 8 to move in the opposite direction. The two rack plates 8 drive the two connecting blocks 9 to move in the opposite direction. The two connecting blocks 9 drive the two moving blocks 10 to move. The two moving blocks 10 drive the limit blocks 11 to move. This is repeated to finally obtain the required data.
[0043] The third step is to obtain the required data, pull the limit block 11, control the test robot 3 to slowly move the protective shell 5 outward, separate the door handle 4 from the limit block 11, and test the vehicle 1 to proceed to the next test item.
[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
