Description

A door body limiter

technical field

The invention relates to a limiting device, in particular to a door body limiting device.

Background technique

The door stop device is widely used in various vehicles. Its main function is to limit the opening of the car door within a certain range. Most of the existing door stoppers are installed on the top of the car door. The door stopper can be adjusted manually. Unlocking, but for relatively high doors, it is difficult for human hands to reach directly, and it is inconvenient to use.

CN103742012A discloses a car door limiter, which includes a car door and a chute arranged on the car door, the car door limiter also includes a limit pin, one end of the limit pin is in the chute Slide left and right along the chute, the other end of the limit pin is installed on the mounting plate on the frame so that the limit pin can rotate freely. When the door reaches the maximum opening range, the door limit device of this invention uses Gravity principle, the limit pin automatically enters the bottom of the chute to realize the automatic limit of the door. When the door is closed, manually lift the limit pin from the bottom of the chute, and then close the door, which can ensure the automatic limit position, but the invention has low reliability, short service life, and is prone to deformation, which finally leads to inaccurate door limit.

Contents of the invention

The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a door body limiting device, which can not only be installed at any position on the upper, middle and lower sides of the car door, is flexible and convenient to use, but also has high reliability and long service life. Long and other advantages.

The technical solution of the present invention is: a door body limit device, a fixed seat, a movable clip, a guide rail seat, a bayonet pin and a torsion spring, one end of the fixed seat is connected to the vehicle wall through a fixing hole, and the other end is connected through a pin It is connected with one end of the movable clip, and the other end of the movable clip is provided with a pin hole, and the bayonet pin is in the pin hole; the guide rail seat is provided with a notch with an inflection point groove at one end, and the bayonet pin is in the pin hole. Slide in the notch, the guide rail seat is installed on the car door through the fixing hole, and the torsion spring is installed at the connection between the fixed seat and the movable clip.

A further technical solution of the present invention is: the movable clamping member is in a "U" shape.

A further technical solution of the present invention is: the torsion spring is made of spring steel wire, and the torsion spring encloses the pin shaft, and the torsion spring can make the movable clip press the guide rail seat to slide and slide the movable clip. The bayonet pin on the part is automatically pressed into the inflection point groove to limit the position.

A further technical solution of the present invention is: the notch is in the shape of a long waist.

Furthermore, the fixed seat, the movable clip, and the guide rail seat are all made of bent steel plates.

Furthermore, the angle formed between the inflection point groove and the notch is 90°.

Compared with the prior art, the present invention has the following characteristics: the door body limit device provided by the present invention adopts the cooperation between the movable seat, the movable clip and the guide rail seat, and a terminal with a The notch of the inflection point groove adopts the principle of the connecting rod mechanism, and a dead point is set as the locking point, which can not only ensure the high reliability of the entire limit device, ensure a long service life, but also ensure the flexible operation of the entire limit mechanism It is convenient and can be installed at any position on the top, middle or bottom of the car door.

The detailed structure of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

detailed description

As shown in the drawings: a door body limit device, fixed seat 6, movable clip 3, guide rail seat 1, bayonet pin 2 and torsion spring 5, one end of the fixed seat 6 is connected with the car wall 9 through the fixed hole 7, The other end is connected with one end of the movable clip 3 through the pin shaft 4, the other end of the movable clip 3 is provided with a pin hole, and the bayonet pin 2 is in the pin hole; the guide rail seat 1 is provided with a groove 1-2 with an inflection point at one end. The notch 1-1, the bayonet pin 2 slides in the notch 1-1, the guide rail seat 1 is installed on the car door 8 through the fixing hole 7, and the torsion spring 5 is installed at the junction of the fixed seat 6 and the movable clip 3.

Movable clamp 3 is " U " shape structure, makes movable clamp 3 be provided with trapezoidal notch, breach is just in the turning point that car wall 9 is connected with door body 8, and flexibility is higher when opening and closing the door.

The torsion spring 5 is made of spring steel wire, and the torsion spring 5 surrounds the pin shaft 4. The torsion spring 5 can make the movable clamp 3 tightly press the guide rail seat 1 to slide and can move the bayonet 2 on the movable clamp 3. Automatically press into the inflection point groove 1-2 to limit.

The notch 1-1 is in the shape of a long waist; the angle between the inflection point notch 1-2 and the notch 1-1 is 90°, which ensures high stability when the door 8 is in the limit state.

The fixed seat 6, the movable clip 3, and the guide rail seat 1 are all made by bending steel plates, have certain rigidity, are not easily deformed, and ensure a long service life.

The working principle and usage method of the present invention are: when the door is opened, the door body 8 drives the guide rail seat 1 to rotate, causing the movable clip 3 to move, and then the movable bayonet 2 moves along the notch 1-1, and finally enters the In the inflection point groove 1-2, the automatic limit is realized. In the above process, the torsion spring 5 can make the movable clamp 3 press the guide rail seat 1 to slide and can automatically press the bayonet 2 on the movable clamp 3 into the inflection point groove. 1-2 middle limit; when closing the door, lift the bayonet 2 by hand, so that the bayonet 2 breaks away from the inflection point groove 1-2 and enters the notch 1-1, and the limit can be released, which is simple and convenient. The reliability is high, and the door body limiting device provided by the present invention can be installed at any position on the top, middle and bottom of the car door, and the installation flexibility is high.
