[0026] Please see all drawings for this manual:

[0027] A clamping device for testing a vehicle door comprises an impact tester body 1, a boss 2 is provided on a working surface of the impact tester body 1, and a vehicle door stabilizing clamping assembly is provided between the impact tester body 1 and the boss 2;

[0028] The door stabilization clamping assembly includes a moving mechanism located in the boss 2, a moving plate 3 is symmetrically provided on the moving mechanism, a limit rod 4 is symmetrically plugged and connected on the moving plate 3, a movable splint 5 is fixedly installed on the limit rod 4, a screw 6 is threadedly connected to the movable splint 5, and the lower end of the screw 6 is rotatably connected to the moving plate 3, a cavity 7 is provided in the movable splint 5, a plurality of grooves 8 are evenly provided on the lower side of the movable splint 5, a through hole 9 is provided between the groove 8 and the cavity 7, a spring 10 is fixedly installed in the groove 8, a fixing rod 11 is fixedly installed on the other end of the spring 10, and a through hole 2 12 is provided on the fixing rod 11, a fan 13 is symmetrically provided on the impact tester body 1, and an air duct 14 is provided on the impact tester body 1 corresponding to the fan 13, one end of the air duct 14 is communicated with the fan 13, and the other end of the air duct 14 is communicated with the cavity 7 through the movable splint 5;

[0029] From the above description, it can be seen that when in use, the car door is first placed on the boss 2. When the movable plates 3 on both sides approach each other through the moving mechanism, the movable plates 3 will first slowly fix the two sides of the car door. Then the staff rotates the screw 6 to make the movable splint 5 drop. The several fixing rods 11 on the movable splint 5 adapt to the shape of the car door under the action of the spring 10. The car door is fixed by the fixing rod 11 at the same time. Then the power supply of the ventilator 13 is connected, and the fan 13 is used to exhaust air, so that the through hole 12 in the fixing rod 11 generates negative pressure on the surface of the car door, so that the fixing effect of the car door is better.

[0030] As a technical optimization solution of the present invention, the moving mechanism includes a motor 15 fixedly mounted on the boss 2, and a second groove 16 is symmetrically provided on the boss 2. A double-threaded screw 17 is rotatably connected in the second groove 16, and the double-threaded screw 17 is fixedly connected to the output end of the motor 15;

[0031] As can be seen from the above description, when the motor 15 is controlled, it drives the double-threaded screw 17 to rotate, so that the movable plates 3 can move closer to or farther away from each other.

[0032] As a technical optimization solution of the present invention, a control button 18 is provided on the impact testing machine body 1, and the control button 18 is electrically connected to the fan 13 and the motor 15;

[0033] From the above description, it can be seen that the staff can easily control the corresponding electrical appliances through the control button 18.

[0034] As a technical optimization solution of the present invention, a lower support plate 19 is fixedly installed on the movable plate 3 corresponding to the movable splint 5;

[0035] As can be seen from the above description, the lower support plate 19 can facilitate the placement of the vehicle door above the boss 2, thereby achieving a better fixing effect of the vehicle door.

[0036] As a technical optimization solution of the present invention, a protective pad 20 is fixedly installed on the opposite side of the movable plate 3;

[0037] It can be seen from the above description that the protective pad 20 can protect both sides of the vehicle door when the vehicle door is clamped by the movable plates 3 on both sides.

[0038] As a technical optimization solution of the present invention, a knob 21 is fixedly mounted on the upper end of the screw rod 6;

[0039] It can be seen from the above description that the knob 21 can facilitate the staff to control the rotation of the screw 6.

[0040] As a technical optimization solution of the present invention, an arc-shaped groove 22 is provided at the lower end of the fixing rod 11 corresponding to the second through hole 12;

[0041] From the above description, it can be seen that the arc-shaped groove 22 enables the fixing rod 11 to have a stronger adsorption ability when it contacts the surface of the car door. Under the negative pressure suction of the fan 13, the structure similar to the suction cup can better fix the car door.

[0042] Working principle:

[0043] When testing the impact ability of the car door, the car door is first placed on the boss 2, and at the same time, it is ensured that the car door is located on the lower support plate 19; the motor 15 is controlled by the control button 18. When the movable plates 3 on both sides approach each other through the moving mechanism, the movable plates 3 will first slowly fix the two sides of the car door, and the protective pads 20 can protect the two sides of the car door; then the staff rotates the knob 21 to turn the screw 6 knob to control the movable splint 5 to descend. Under the action of the spring 10, the several fixing rods 11 on the movable splint 5 adapt to the shape of the car door, and the car door is fixed by the fixing rods 11 at the same time. Then the power supply of the ventilator 13 is connected, and the fan 13 is used to exhaust air, so that the through hole 2 12 and the arc-shaped groove 22 in the fixing rod 11 generate negative pressure on the surface of the car door, so that the fixing effect of the car door is better.

[0044] The above description of the present invention and its embodiments is non-limiting. The specific embodiments shown in the specific embodiments are only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
