Description

Technical Field

[0001] This utility model relates to the field of automotive testing, and in particular to a testing device for vehicle door opening and closing. Background Technology

[0002] As a crucial means of transportation, automobiles are seeing increasing ownership and sales volume year by year. The door assembly is a vital component of a car and one of the most important opening and closing mechanisms, playing a crucial role in ensuring the safety of occupants. Because doors significantly impact the overall quality of a vehicle, all marketed car models undergo door opening and closing durability tests to verify the reliability of the door assembly.

[0003] Existing car door testing devices typically use a robotic arm to push the door closed during testing. After the door is closed, staff need to manually open it to its maximum opening angle. However, since car door tests usually require more than 100,000 tests, it is very time-consuming to have staff manually open the door.

[0004] Therefore, it is necessary to provide a new testing device for vehicle door opening and closing to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a testing device for car door opening and closing, which solves the problem that existing car door tests usually require more than 100,000 tests, so it is very time-consuming for staff to manually open the car door.

[0006] The testing device for car door opening and closing provided by this utility model includes a base fixed at the work site and a car door to be tested. A door handle is installed on the car door to be tested, a rotating platform is installed on the base, and a support frame is fixed on the top of the rotating platform.

[0007] A lifting column is installed through the support frame, and the lifting column is slidably connected to the support frame. A connecting seat is installed on the top of the lifting column, and a force-applying seat is fixed to one side of the connecting seat by a side rod. A bionic finger rod is installed on one side of the force-applying seat.

[0008] A door opening assembly is provided on one side of the rotating platform.

[0009] In a preferred embodiment, the base is configured as a trapezoid.

[0010] In a preferred embodiment, an electric telescopic rod is installed on the top of the rotary table, and the output end of the electric telescopic rod is fixedly connected to the bottom of the lifting column.

[0011] In a preferred embodiment, a gear ring is mounted on the rotating platform, a motor is mounted on the base, a gear is mounted on the output end of the motor, and the gear ring meshes with the gear.

[0012] In a preferred embodiment, the door opening assembly includes an electric reel and a pull cord, and a mounting platform is fixed on the base, with a limit seat fixed on one side of the mounting platform.

[0013] The electric winding reel is mounted on the limiting seat, and the pull rope is wound on the electric winding reel. The end of the pull rope away from the electric winding reel is fixed to the door handle.

[0014] In a preferred embodiment, a laser velocimeter is detachably mounted on the top of the mounting platform by bolts.

[0015] The beneficial effects of this utility model are:

[0016] When using this testing device, the operator can first use a forklift to move the base to the door handle of the car door to be tested. After it is fixed, during the test, the operator starts the electric reel to move the door handle and open the car door. After the car door is open, the operator can start the motor. Under the transmission of gears and gear rings, the turntable will rotate, which will eventually drive the side rod to swing. The simulated finger rod on the side rod applies force to the car door, causing the car door to close. This solves the problem of the time wasted by the operator manually opening the car door. At the same time, this device has a simple structure and low cost, making it suitable for widespread use. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A perspective view of the main structure of the testing device for vehicle door opening and closing provided by this utility model; Figure 2 A front view of the main structure of the testing device for vehicle door opening and closing provided by this utility model; Figure 3 The main structural top view of the testing device for car door opening and closing provided by this utility model.

[0023] In the specific implementation process, such as Figures 1-3 As shown, the test includes a base 1 fixed at the work site and a test door 2. The base 1 is trapezoidal to increase its stability during use. A door handle 3 is installed on the test door 2. A rotating platform 4 is installed on the base 1. A support frame 5 is fixed on the top of the rotating platform 4. A gear ring 12 is installed on the rotating platform 4. A motor 13 is installed on the base 1. A gear 14 is installed at the output end of the motor 13. The gear ring 12 meshes with the gear 14. Starting the motor 13 can drive the gear 14 to rotate. Under the transmission action of the gear 14 and the gear ring 12, the rotating platform 4 will rotate and drive the side rod 8 to swing.

[0024] A lifting column 6 is installed through the support frame 5. The lifting column 6 is slidably connected to the support frame 5. A connecting seat 7 is installed on the top of the lifting column 6. A force-applying seat 9 is fixed to one side of the connecting seat 7 via a side rod 8. A bionic finger rod 10 is installed on one side of the force-applying seat 9. A door opening assembly is installed on one side of the rotating platform 4. The door opening assembly includes an electric winding and unwinding reel 15 and a pull rope 16. An installation platform 17 is fixed on the base 1. A limit seat 19 is fixed to one side of the installation platform 17. The electric winding and unwinding reel 15 is installed on the limit seat 19. A pull rope 16 is wound on the electric winding and unwinding reel 15. The end of the pull rope 16 away from the electric winding and unwinding reel 15 is fixed to the door handle 3. During testing, the staff starts the electric winding and unwinding reel 15 to move the door handle 3, thereby opening the car door.

[0025] The movement of the output end of the electric telescopic rod 11 can drive the lifting column 6 to move up and down, thereby enabling the force-applying seat 9 to apply a pushing force to the door at different heights.

[0026] A laser velocimeter 18 is detachably mounted on the top of the mounting platform 17 via bolts. This laser velocimeter 18 utilizes the principle of laser ranging, determining the distance between the object and the test point by emitting a laser beam towards the object being measured, receiving the reflected laser beam, and recording the time difference. The laser velocimeter measures the distance to the object twice at specific time intervals to obtain the distance the object has moved during that time period, thus determining the object's speed.

[0027] The working principle of this utility model is as follows: When using this testing device, the operator can first use a forklift to move the base 1 to the door handle 3 of the door 2 to be tested. After fixing it, during the test, the operator starts the electric winding reel 15 to move the door handle 3, thereby opening the door. After the door is opened, the operator can start the motor 13 to drive the gear 14 to rotate. Under the transmission action of the gear 14 and the gear ring 12, the rotating table 4 will rotate, which will eventually drive the side rod 8 to swing. The simulated finger rod 10 on the side rod 8 applies force to the door, causing the door to close. This solves the problem that it is very time-consuming for the operator to manually open the door. At the same time, this device has a simple structure and low cost.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
