Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a test bench for testing the anti-pinch force of frameless car doors. Background Technology
[0002] With the changing design philosophy of automobiles, some cars will adopt frameless doors, which not only improves the aesthetics but also reduces obstruction of the view, making them popular among consumers and with a broad market prospect.
[0003] To ensure vehicle safety, frameless doors require anti-pinch force testing. Currently, existing methods for testing door anti-pinch force typically involve fixing an obstacle and / or an anti-pinch force testing device to the upper frame of the door. During the test, the door is raised and lowered, and the glass contacts the obstacle and / or the testing device at different positions, thus testing the anti-pinch force during the door's movement. However, because frameless doors lack a traditional frame structure, it is difficult to fix the obstacle and / or the testing device to the window using traditional methods, making it difficult to meet testing requirements. In other words, there is currently no device specifically designed for testing the anti-pinch force of frameless doors. Furthermore, existing methods for testing the anti-pinch force of vehicle windows are limited by the structural layout of the vehicle frame, which restricts the flexible adjustment of the positions of obstacles and anti-pinch force testing instruments. This necessitates repeated installation and removal of obstacles and testing instruments on the vehicle frame, resulting in a complex and inefficient testing process. Moreover, the limited number of locations available for installing obstacles and testing instruments means that only certain areas of the window can be monitored, lacking comprehensive test point coverage. Consequently, the accuracy of existing anti-pinch force test results is insufficient, making it difficult to accurately and completely evaluate the true performance of the anti-pinch system and impacting its application in vehicle doors. Summary of the Invention
[0004] To address the aforementioned problems in existing technologies, this invention aims to provide a test bench for testing the anti-pinch force of frameless car doors. The bench is equipped with a door fixing clamp to hold the frameless car door to be tested, and includes a horizontal lateral sliding component. A horizontal longitudinal sliding component and a lifting component are mounted on the horizontal lateral sliding component. This allows the lifting component to be adjusted to any position in the horizontal plane under the action of the horizontal and longitudinal sliding components. Combined with its own lifting motion, it can be adjusted to any position in space. By using the lifting component as an obstacle or mounting an anti-pinch force testing instrument, the testing requirements for any test point on the frameless car door can be met. Furthermore, no structural additions to the frameless car door are required, making operation simpler, adjustment more convenient, and testing efficiency higher. It also ensures the accuracy of the test results, providing a precise and complete evaluation of the performance of the window anti-pinch system.

[0027] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.
[0028] Figure 1This is a structural diagram of an embodiment of a test bench for testing the anti-pinch force of frameless car doors according to the present invention. Figure 1 As shown, the test bench for anti-pinch force testing of frameless car doors provided in this embodiment includes: a frame body 1, a car door fixing clamp 2, a horizontal lateral sliding member 3, a horizontal longitudinal sliding member 4, and a lifting member 5.
[0029] Specifically, the frame 1 includes a base 11 and a top frame 12. The base 11 is placed horizontally on the ground, serving as a carrier for the frameless car door to be tested, supporting the frameless car door. The top frame 12 is horizontally arranged and spaced above the base 11, forming a support platform at a predetermined height above the base 11, providing a carrier for the subsequent installation of obstacles and / or anti-pinch force testing equipment.
[0030] Specifically, the door fixing clamp 2 is installed on the frame body 1 so that when the frameless door to be tested is placed on the base 11, the door fixing clamp 2 can clamp the frameless door to be tested, ensuring that the frameless door to be tested can maintain stability during the test, preventing the frameless door to be tested from tipping over or other problems, and ensuring the accuracy and effectiveness of the test structure.
[0031] Specifically, the horizontal sliding component 3 is set on the top frame 12 and slides on the top frame 12 in one direction in the horizontal plane, so that the horizontal sliding component 3 can adjust its position relative to the frameless car door to be tested through its own sliding, thereby providing conditions for subsequent testing of different test points on the frameless car door to be tested.
[0032] Specifically, the horizontal longitudinal sliding member 4 is slidably mounted on the horizontal transverse sliding member 3, so that the horizontal longitudinal sliding member 4 can both move with the horizontal transverse sliding member 3 and move on its own within the horizontal plane. At this time, the sliding direction of the horizontal longitudinal sliding member 4 on the horizontal transverse sliding member 3 is perpendicular to the sliding direction of the horizontal transverse sliding member 3 on the top frame 12. With the horizontal transverse sliding member 3 and the horizontal longitudinal sliding member 4 moving in coordination, the horizontal longitudinal sliding member 4 can be moved to any position within the horizontal plane, further providing conditions for subsequent testing of different test points on the frameless door to be tested.
[0033] Specifically, the lifting component 5 is mounted on the horizontal longitudinal sliding component 4, and moves vertically up and down on the horizontal longitudinal sliding component 4. This allows the lifting component 5 to move with both the horizontal transverse sliding component 3 and the horizontal longitudinal sliding component 4, while also allowing for vertical height adjustment, enabling it to be positioned at any point in space. Furthermore, one end of the lifting component 5 can be an obstacle end or have an anti-pinch force testing device mounted on it. This means the obstacle end of the lifting component 5 or the anti-pinch force testing device mounted on it can move to any position in space, ensuring comprehensive coverage of all test points on the frameless door under test. This improves the accuracy of the test results and allows for a more precise and complete evaluation of the actual performance of the window anti-pinch system. Moreover, the testing process is not affected by the door's structure; it acts directly on the glass. The structure is simple, and adjusting the test points is more convenient, eliminating the need for repeated disassembly and reassembly of obstacles and the anti-pinch force testing device, thus simplifying operation and increasing testing efficiency. In addition, it can adapt to anti-pinch force testing of frameless doors of different models and with different design requirements, making the testing more flexible and adaptable, thereby improving the utilization rate of the test bench.
[0034] More specifically, the frame 1 also includes columns 13 and reinforcing rods 14. Several columns 13 are provided, positioned between the base 11 and the top frame 12. The upper and lower ends of each column 13 are fixedly connected to the top frame 12 and the base 11, respectively. This ensures the top frame 12 is stably supported above the base 11, maintaining its stability. The columns 13 also connect the top frame 12 and the base 11, forming a unified structure with higher structural strength and load-bearing capacity. Furthermore, the frame features internal self-locking, guaranteeing the stability of each structure during testing. The structural design is more rational. Simultaneously, the reinforcing rods 14 are placed within the base 11, with both ends fixedly connected to the bottom rods at both ends of the base 11. The reinforcing rods 14 enhance the overall integrity of the base 11, resulting in a taller overall structure, making the base 11 more robust and the test results more accurate and reliable.
[0035] More specifically, the base 11 also includes a base post 15, which is arranged in a horizontal plane and parallel to the sliding direction of the horizontal transverse sliding member 3 or the horizontal longitudinal sliding member 4. The base post 15 further strengthens the structural strength of the base 11. In addition, a door placement groove 151 arranged in the same direction is provided on the base post 15. That is, the door placement groove 151 forms a recessed part on the base post 15, so that when the frameless door to be tested is placed on the base 11, the bottom of the frameless door to be tested can be placed in the door placement groove 151, realizing the rapid positioning of the frameless door to be tested. At the same time, it can also realize the bottom limit of the frameless door to be tested, further improving the stability of the frameless door during the testing process and ensuring the accuracy of the test results.
[0036] Figure 2 for Figure 1 An enlarged view of section A. (See image below.) Figure 1 and Figure 2 As shown, the door fixing clamp 2 includes a fixing rod 21, two clamp baffles 22, and door fixing locking screws. The fixing rod 21 is horizontally arranged and its two ends are fixedly connected to the two columns 13, realizing the stable installation of the fixing rod 21 on the frame body 1. Preferably, the fixing rod 21 is arranged perpendicular to the bottom column 15. Since the door placement groove 151 on the bottom column 15 is used to place the bottom of the frameless door to be tested, the bottom column 15 is arranged along the length direction of the frameless door to be tested. Therefore, the arrangement direction of the fixing rod 21 is the thickness direction of the frameless door to be tested, thus providing the conditions for clamping from both sides of the frameless door to be tested. At this time, a clamping slot 211 is opened in the same direction on the fixed support rod 21. One side of each of the two clamping baffles 22 is slidably disposed in the clamping slot 211. This allows the distance between the two clamping baffles 22 to be adjusted when they slide within the clamping slot 211, so that the two clamping baffles 22 can clamp the frameless car door to be tested from both sides. This ensures that the frameless car door to be tested can be stably placed within the frame body 1, ensuring that the frameless car door remains stable during the test and preventing problems such as tipping or movement under force, thus ensuring the accuracy of the test results. In addition, the clamping baffles 22 can be adjusted to adapt to the clamping requirements of different models and design requirements of frameless car doors, resulting in greater structural flexibility. Preferably, each clamping baffle 22 corresponds to a door fixing screw. In this case, a clamping relief groove 212 is formed on the fixing rod 21 in the same direction. One side of the clamping relief groove 212 is connected to the clamping slot 211, so that the clamping relief groove 212 can be arranged parallel to the clamping slot 211. That is, the clamping relief groove 212 can adapt to the movement requirements of the clamping baffle 22 at any position in the clamping slot 211. Furthermore, after the door fixing screw passes through the clamping relief groove 212, it is threadedly connected to the corresponding clamping baffle 22. That is, when the door fixing screw is loosened, the clamping baffle 22 can slide in the clamping slot 211, and the clamping relief groove 212 is used to adapt to the sliding, preventing the door fixing screw from being blocked and the clamping baffle 22 from sliding. Conversely, when the door fixing screw is tightened, the clamping baffle 22 can be temporarily fixed in a part of the clamping slot 211, making the operation more convenient.
[0037] Figure 3 for Figure 1 A magnified view of section B. (See image below.) Figure 1 and Figure 3As shown, the horizontal sliding component 3 includes two horizontal guide rails 31, two horizontal sliders 32, and a horizontal sliding rod 33. The two horizontal guide rails 31 are respectively mounted on the top rods at both ends of the top frame 12. The two horizontal sliders 32 are slidably mounted on the two horizontal guide rails 31. Both ends of the horizontal sliding rod 33 are fixedly connected to the two horizontal sliders 32, ensuring that both ends of the horizontal sliding rod 33 are supported and guaranteeing the stability of the horizontal sliding rod 33 after position adjustment. This also allows the horizontal sliding rod 33 to adjust its position when the horizontal sliders 32 slide relative to the horizontal guide rails 31, thus meeting different testing requirements. Additionally, a horizontal locking screw is threaded onto the horizontal slider 32. One end of the horizontal locking screw abuts against the corresponding horizontal guide rail 31. Tightening the horizontal locking screw temporarily locks or loosens the horizontal slider 32 on the horizontal guide rail 31, thus meeting adjustment requirements.
[0038] More specifically, the horizontal longitudinal sliding member 4 includes a longitudinal slider 41. A longitudinal groove 331 is formed on the transverse slide rod 33 along its arrangement direction. Simultaneously, one side of the longitudinal slider 41 is slidably disposed within the longitudinal groove 331, enabling position adjustment of the longitudinal slider 41 in another direction within the horizontal plane. Furthermore, a longitudinal clearance groove 332, parallel to and connected to the longitudinal groove 331, is also formed on the transverse slide rod 33. A longitudinal locking screw passes through the longitudinal clearance groove 332 and is threadedly connected to the longitudinal slider 41. That is, by tightening the longitudinal locking screw, the longitudinal slider 41 is temporarily locked or released within the longitudinal groove 331, thereby satisfying the position adjustment of the longitudinal slider 41 in another direction within the horizontal plane and meeting the usage requirements.
[0039] More specifically, the lifting component 5 is a lifting rod 51. The lower end of the lifting rod 51 is an arc-shaped surface, which serves as the actual usable end for forming obstacles or installing an anti-pinch force tester. Preferably, the longitudinal slider 41 has a lifting hole 411 in the vertical direction, and the lifting rod 51 passes through the lifting hole 411. At the same time, the longitudinal slider 41 also has a lifting adjustment hole 412 that communicates with the lifting hole 411. A lifting adjustment screw is threaded to the lifting adjustment hole 412 and one end abuts against the part of the lifting rod 51 located in the lifting hole 411. The lifting rod 51 can be tightened or loosened by turning the lifting adjustment screw, which meets the needs of temporarily fixing or adjusting the lifting rod 51 in the lifting hole 411, making operation more convenient and easier to adjust.
[0040] In addition, in this embodiment, for the structure of the horizontal sliding member 3, the two horizontal guide rails 31 can be replaced with two horizontal sliding grooves. In this case, the two horizontal sliding grooves are respectively set on the top rods at both ends of the top frame 12, and the two horizontal sliders 32 are respectively slidably set in the two horizontal sliding grooves. The two ends of the horizontal sliding rod 33 are respectively fixed on the two horizontal sliders 32, which can also achieve support for the two ends of the horizontal sliding rod 33, improve the stability of the horizontal sliding rod 33 after installation, and at the same time, it can also adapt to the sliding requirements of the horizontal sliding rod 33 in one direction in the horizontal plane. In addition, the top rods at both ends of the top frame 12 are provided with horizontal clearance grooves that are parallel to and connected to the horizontal sliding grooves. The horizontal locking screw passes through the horizontal clearance groove and is threadedly connected to the horizontal slider 32. That is, by turning the horizontal locking screw, the horizontal slider 32 can be temporarily fixed or loosened in the horizontal sliding groove, thereby meeting the position adjustment requirements of the horizontal sliding rod 33.
[0041] In a preferred embodiment, a mounting block is detachably installed at the lower end of the lifting rod 51. When installing the anti-pinch force tester on the lifting component 5, the mounting block can serve as the mounting carrier for the anti-pinch force tester, providing a larger mounting surface, making installation more convenient, and resulting in higher stability after installation. Preferably, the mounting block has a clamping hole with an opening, through which the lower end of the lifting rod 51 is clamped. At the same time, a clamping screw is provided on the mounting block at both ends of the opening of the clamping hole. The size of the opening of the clamping hole can be adjusted by turning the clamping screws, which facilitates the installation and removal of the mounting block at the bottom of the lifting rod 51, resulting in a more reasonable structural design.
[0042] As a further preferred embodiment, the bottom of the frame 1 is provided with a plurality of casters 6. In this case, the casters 6 are located at the bottom of the base 11. To ensure overall stability, the casters 6 are evenly distributed on the base 11. The casters 6 increase the overall mobility of the frame 1, facilitating positional movement when testing is required, improving flexibility, and meeting different testing needs. Preferably, the casters 6 are omnidirectional wheels, and all or part of the omnidirectional wheels are equipped with brakes, enabling movement in any direction, further improving mobility, and locking the casters 6 during testing, further improving testing stability and ensuring the accuracy of the test structure.
[0043] The test bench for frameless car door anti-pinch force testing provided in this embodiment includes a frame body 1, a car door fixing clamp 2, a horizontal lateral sliding member 3, a horizontal longitudinal sliding member 4, and a lifting member 5. By setting the car door fixing clamp 2 on the frame body 1, the frameless car door to be tested, placed on the base 11 of the frame body 1, is clamped to ensure stability during testing.
