Abstract

The invention belongs to the technical field of car door stoppers, in particular to a car door stopper, which includes a mounting bracket fixed on the car body, a limit box fixed on the car door, a rubber buffer block for providing buffer force, a stopper Arm, clamping mechanism, the car door limiter designed by the present invention, by designing the limiting plane of the upper and lower side limit protrusions of the limiter arm, the work of the upper side compression spring and the lower side compression spring of the limiter in the working process Depending on the state, the time to cause the spring to fail and become weak is different. Through the elastic force of the spring that fails slowly to cooperate with the adjustment mechanism, and through the extrusion of the extrusion block to the second rack, the pre-compression of the upper compression spring and the lower spring is increased. Weaken the reduction degree of the resistance torque after the stopper works for a long time.

Description

[0001] Technical field

[0002] The invention belongs to the technical field of car door stoppers, in particular to an automobile door stopper. Background technique

[0003] At present, when the vehicle is manufactured, a door stopper, a rubber spring stopper and a torsion spring stopper are installed on the car door. The car door stopper generally has the following two functions: one is the stopper arm Set 2-3 arc belts on the top, so as to form switch gears at the nodes of the arc belts and arc belts, so that the door has 2-3 positioning points during the opening and closing process; the second is to ensure that the car is on the specified ramp. It can ensure that the door stops at a certain fixed point and does not open or close by itself. The advantages of this structure are simple structure, low cost, small footprint, and maintenance-free; the disadvantage is that the limit torque decreases rapidly after a period of operation.

Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples or drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0034] like figure 1 As shown, it includes a mounting bracket 4 fixed on the car body, a limit box 3 fixed on the door, a rubber buffer block 1 providing a buffer force, a limit arm 2, and a clamping mechanism 11, wherein as figure 2 As shown, the upper and lower ends of the limit arm 2 are respectively provided with two limit protrusions 6 distributed along the length direction of the limit arm 2, and one end of the limit arm 2 is mounted on the mounting bracket 4 in a hinged manner, and the rubber The buffer block 1 is installed on the other end of the limit arm 2, and is limited by the pin installed on the limit arm 2; the limit arm 2 passes through the limit box 3 and...
