Embodiment 1

[0027] Embodiment 1: as figure 2 , 3 Shown: a door stopper, including a static end 1 and a moving end 2, the static end 1 has a wedge-shaped hole, one end of the moving end 2 is provided with a wedge-shaped tongue, and the other end is provided with an inner shaft seat 7, when When the door is closed, the wedge-shaped tongue falls into the wedge-shaped hole, a stopper 3 is also provided on the static end 1, and an inner shaft hole a with the upper end closed is provided on the inner shaft seat 7 of the moving end 2. An inner shaft 5 is installed in the inner shaft hole a, and both ends of the inner shaft 5 protrude from the inner shaft hole a;

[0028] The inner shaft 5 is composed of a collision section, a guide section and a switch section, wherein the collision section faces the stopper 3, the diameter of the collision section is larger than the guide section, and a return spring 4 is set on the guide section, and the return spring 4 It is limited between the top surface...

Embodiment 2

[0035] Embodiment 2: as Figure 6 As shown: the wedge-shaped hole is a blind hole, and the stopper 3 is the bottom of the blind hole.

Embodiment 3

[0036] Embodiment 3: as Figure 5 As shown: the block 3 is located outside the wedge-shaped hole, the inner shaft seat 7 on the movable end 2 is located outside the wedge-shaped tongue, and the inner shaft seat 7 is located directly above the block 3 .

[0037] The working principle of the present invention is:

[0038] The static end 1 is fixed on the door frame, and the moving end 2 is fixed on the door. The wedge-shaped hole and the wedge-shaped tongue realize the limit function of the door. When the door is closed, the moving end 2 and the static end 1 are closed, and the wedge-shaped tongue is inserted into the wedge-shaped groove. Inside, the door forms position restrictions in the up and down and left and right directions, preventing the door from moving in these two directions when the vehicle is moving, ensuring the safety of the vehicle.

[0039] The stroke of the inner shaft 5 is limited by the stopper 3, and the inner shaft 5 drives the moving contact 6 to separat...

Abstract

The invention discloses a car door limiter which comprises a fixed end and a mobile end, wherein the fixed end is provided with a wedge-shaped hole, and the mobile end is provided with a wedge-shaped tongue. The car door limiter is characterized in that a stop block is also arranged on the fixed end, an inner shaft is arranged in an inner shaft hole, and the inner shaft comprises a collision section, a guide section and a switch section, wherein the collision section faces to the stop block, the diameter of the collision section is larger than that of the guide section, a reset spring is sleeved on the guide section, the reset spring is limited between the top surface of the collision section and a shrinkage port at the upper end of the inner shaft hole, the switch section is positioned outside the inner shaft hole, and a mobile contact is arranged on the switch section; and a fixed contact is also arranged on the mobile end. The invention has the remarkable effects that the structure is simple just by carrying out slight change on a production die of the original car door limiter, and the cost is low; whether a car door is closed or not can also be detected while a limit function between the car door and a door frame is provided, a plurality of functions are integrated together with reasonable design, compact structure, convenient installation and low cost, and the assembling procedures are reduced.

Description

technical field [0001] The invention is mainly used in the technical field of sliding car door control, in particular to a car door limiter. Background technique [0002] Sliding doors mainly appear on the side body of vans, commercial vehicles, etc., and the sliding doors do not occupy the space of the body. But opening and closing the car door requires a lot of strength, and the alignment technology of the car door is more difficult than ordinary sliding doors. Therefore, a car door stopper is installed on the car door, and the common car door stopper includes a static end and a moving end, and the static end is fixed on the door frame, and the moving end is fixed on the sliding door. [0003] Such as figure 1 As shown: the static end has a wedge-shaped hole, and the moving end is provided with a wedge-shaped tongue. When the door is closed, the wedge-shaped tongue falls into the wedge-shaped hole. The two realize the relative positioning between the door and the door fr...
