Abstract

The utility model relates to the production and manufacturing field of passenger cars, in particular to a light-weight car door limiter component; the automobile door limiting device comprises a limiting arm, a connecting support, a rotating shaft and a housing, wherein one end of the limiting arm is rotatably connected with the connecting support through the rotating shaft, the housing is arranged on the limiting arm in a penetrating mode, and the whole automobile door limiting device assembly is connected with an automobile body and an automobile door through the housing and the connecting support respectively; the method is characterized in that: the whole surface of the cover shell is wrapped by the injection molding layer. This door stopper subassembly adopts above-mentioned structural design, through adopting the plastics material on housing and spacing arm, and then reduces the occupation of area ratio of metal material to set up the top layer of plastics material on the surface of housing and spacing arm, and then produce the abnormal sound that the metal knocks the sound and send and arouse when avoiding stopper or housing and automobile body or door to take place to contact. Meanwhile, the door limiter assembly adopts an injection molding process on a large scale, so that the waste phenomenon of materials in a stamping process is avoided.

Description

Light-weighted car door limiter subassembly

Technical Field

The utility model relates to a field is made in the production of passenger car, specifically is a lightweight car door limiter subassembly.

Background

The door check device is used for connecting a vehicle door with a vehicle body and limiting the opening range of the vehicle door, and is a very common automobile part on the whole. As shown in fig. 1 and 2, the conventional door check 6 has a metal shell 7, so that the weight of the single door check is large and the metal shell needs to be manufactured by a stamping process, thereby generating expensive design and manufacturing cost of the die. Meanwhile, the dimension tolerance of the product which cannot be avoided in the stamping manufacturing process can also generate abnormal sound in the actual use process of the limiter.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned defect, provide a can reduce single product weight and be difficult for producing the car door stop that the metal strikeed the abnormal sound.

In order to achieve the above object, the present invention is realized as follows:

a light-weight vehicle door limiter assembly comprises a limiting arm, a connecting support, a rotating shaft and a housing, wherein one end of the limiting arm is rotatably connected with the connecting support through the rotating shaft, the housing is arranged on the limiting arm in a penetrating mode, and the whole vehicle door limiter assembly is connected with a vehicle body and a vehicle door through the housing and the connecting support respectively; the whole surface of the cover shell is wrapped by the injection molding layer.

The light-weight vehicle door limiter assembly is characterized in that the whole housing is made of a plastic material.

In the light-weight vehicle door limiter assembly, the whole surface of the limiting arm is wrapped by the injection layer, and the upper side and the lower side of the inner part of the housing are provided with the sliding blocks made of plastic materials; the slider slides along the upper surface and the lower surface of the limiting arm to realize the segmented limiting, namely the purpose of opening the vehicle door in a segmented manner.

This door stopper subassembly adopts above-mentioned structural design, through adopting the plastics material on housing and spacing arm, and then reduces the occupation of area ratio of metal material to set up the top layer of plastics material on the surface of housing and spacing arm, and then produce the abnormal sound that the metal knocks the sound and send and arouse when avoiding stopper or housing and automobile body or door to take place to contact.

Fig. 2 is a schematic structural diagram of a conventional door checker assembly.

Fig. 3 is a schematic structural diagram of the present door checker assembly.

Detailed Description

The invention is further illustrated by the following specific examples.

As shown in fig. 3, a light-weight vehicle door check device assembly includes a check arm 1, a connecting bracket 2, a rotating shaft 3 and a cover 4, wherein one end of the check arm 1 is rotatably connected with the connecting bracket 2 through the rotating shaft 3, the cover 4 is arranged on the check arm 1 in a penetrating manner, and the whole vehicle door check device assembly is connected with a vehicle body and a vehicle door through the cover 4 and the connecting bracket 2; the entire surface of the cover 4 is covered by an injection molded layer.

The light-weight car door limiter assembly is characterized in that the whole housing 4 is made of injection molding materials.

In the light-weight vehicle door limiter assembly, the whole surface of the limiting arm 1 is wrapped by the injection layer, and the upper side and the lower side of the inner part of the housing 4 are provided with the sliding blocks 5 made of plastic materials; the sliding block 5 slides along the upper surface and the lower surface of the limiting arm to realize the segmented limiting, namely the purpose of opening the vehicle door in a segmented manner.

In the door check assembly, the injection molding raw material is selected from high-strength nylon materials (PA 66+33 GF), so that the strength is better than that of a metal material.

This door stopper subassembly adopts above-mentioned structural design, through adopting the plastics material on housing 4 and spacing arm, and then reduces the proportion of metal material to set up the top layer of plastics material on the surface of housing 4 and spacing arm, and then produce the abnormal sound that the metal knocks the sound transmission and arouse when avoiding stopper or housing 4 and automobile body or door to take place to contact. Meanwhile, the door limiter assembly adopts an injection molding process on a large scale, so that the waste phenomenon of materials in a stamping process is avoided.
