Description

Technical Field

[0001] This utility model relates to the technical field of vehicle door performance testing devices, specifically to a vehicle door durability testing device. Background Technology

[0002] Car doors are one of the main components of a vehicle. Their primary function is to seal off the interior of the vehicle, ensuring that the interior is not affected by the outside world while the vehicle is in motion, and also ensuring the safety of the passengers. Because vehicles are used for a long time, car doors are frequently opened and closed, so the requirements for car doors are also very high.

[0003] After vehicle production and assembly are completed, testing is required. The testing of car doors mainly involves testing their opening and closing life. Currently, the basic method is to control the opening and closing of the car door using telescopic rods or multi-stage linkage rods. This method can only test the door hinges. After the car door is closed, the handle needs to be pulled to open it. However, the current testing equipment does not have the relevant components, which means that the car door cannot be completely closed each time it is opened and closed, reducing the reliability of the test. Therefore, a car door durability testing device is proposed. Utility Model Content

[0004] The technical problem this invention aims to solve is that a car door needs to be opened by pulling the handle after it is closed.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The present invention relates to a vehicle door durability testing device, comprising a base 1, a horizontal guide rail 3 on the top of the base 1, a vertical guide rail 5 above the horizontal guide rail 3, a slider 4 slidably connected to both the horizontal guide rail 3 and the vertical guide rail 5, a fixing block 6 fixedly connected to one side of the slider 4 on the vertical guide rail 5, a telescopic rod 7 detachably embedded in the fixing block 6, a vertical plate 8 at the output end of the telescopic rod 7, a hook 9 slidably connected to the side of the vertical plate 8 away from the telescopic rod 7, an anti-slip pad 16 fixedly connected to the inner wall of the hook 9, and the hook 9 being an L-shaped knot;

[0019] Two grooves are provided on the side wall opposite to the hook 9 of the vertical plate 8, and a slider 4 is slidably connected in the groove. One end of the hook 9 is detachably connected to one end of the slider 4. A connecting post 11 is provided on the side of the vertical plate 8 away from the hook 9. A driver 12 is detachably embedded in the connecting post 11 and the side wall opposite to the vertical plate 8. The output end of the driver 12 is detachably connected to the middle of one side wall of the vertical plate 8.

[0020] The technical effect of this solution is as follows: the slider 4 connected to the horizontal guide rail 3 can drive the vertical guide rail 5 to move horizontally, while the slider 4 on the vertical guide rail 5 can drive the vertical plate 8 to rise and fall vertically, thus adapting to different sizes and models of vehicle doors, ensuring that the hook 9 can accurately lock onto the handle. After adjusting the orientation angle of the hook 9 according to the handle shape, after the hook 9 is locked onto the handle, the telescopic rod 7 is activated to drive the hook 9 to move backward, thereby pulling the handle open and opening the door's locking structure. Then, the motor 2 is activated to drive the horizontal guide rail 3 and the vertical guide rail 5 to move, thus opening the door. Repeating this step can test the hinge durability of the door, and it is a complete process of door opening and closing, ensuring the reliability of the test data.

[0021] Two semi-circular mating blocks 13 are fixedly connected to the side wall of the connecting column 11 away from the driver 12. An insert block 14 is inserted between the two mating blocks 13. Linkage columns 15 are fixedly connected to both sides of the insert block 14. The insert block 14 is rotatably connected between the two mating blocks 13 through the linkage columns 15. One end of the insert block 14 is detachably connected to the output end of the telescopic rod 7. A motor 2 is detachably embedded at the top of the base 1. The output end of the motor 2 is detachably connected to the bottom side wall of the horizontal guide rail 3 near one end. A wedge plate is fixedly connected to one side of the output end of the motor 2, and the wedge plate is detachably connected to the bottom side wall of the horizontal guide rail 3. A rotating shaft 10 is detachably connected to the bottom side wall of the vertical guide rail 5. The rotating shaft 10 is detachably embedded at the bottom end of the top side wall of the slider 4 on the horizontal guide rail 3.

[0022] The technical effects of this solution are as follows: To ensure smooth door opening and closing control, the vertical plate 8 is rotatably connected to the insert block 14 via the docking block 13 on one side. This allows the vertical plate 8 to rotate and adjust itself as needed during door opening and closing, ensuring smooth movement. The anti-slip pad 16 connected inside the hook 9 is to prevent scratches on the door handle. At the same time, the anti-slip pad 16 increases friction and ensures the stability of the engagement.

[0023] Specifically, when using this invention, the test vehicle is first moved to the designated position. Then, the positions of the vertical guide rail 5 and the fixing block 6 are adjusted according to the position of the door handle. Next, the driver 12 is activated to rotate and adjust the orientation of the hook 9 according to the door handle. Then, the telescopic rod 7 is activated to push out the vertical plate 8, controlling the hook 9 to move so that it is locked onto the door handle. Then, the hook 9 is controlled to retract via the telescopic rod 7, during which the handle is pulled open. Then, the motor 2 is activated to control the horizontal guide rail 3 to rotate and move until the door is fully opened. Then, the door is closed and locked by reversing. Repeating this step can achieve the durability test of the door. Because the vertical guide rail 5 and the horizontal guide rail 3 are rotatably connected, they can automatically rotate and adjust with the movement, avoiding movement interference. (In this article, the movement of the slider 4 and the hook 9 are controlled by cylinders, which are existing technologies and will not be described in detail.)
