Description

Automobile door decoration, automobile threshold decoration and mutual matching structure thereof

Technical Field

The utility model relates to the technical field of automobile door and threshold decoration parts, in particular to an automobile door decoration part, an automobile door decoration part and a mutual matching structure thereof.

Background

The automobile door decorating part is used for wrapping the bottom edge of the automobile door, so that the automobile door decorating part not only plays an attractive role, but also can prevent the automobile paint from being scratched and avoid the corrosion problem of the surface of the automobile after being corroded by silt, rainwater and the like in the running process. The automobile door threshold decoration is installed at the automobile door threshold, and a door threshold reinforcement is arranged on the automobile door threshold for protecting and reinforcing the automobile door threshold, and the automobile door threshold decoration can be installed on the door threshold reinforcement, so that the automobile door threshold decoration also plays roles of attractive appearance and protection. Meanwhile, after the door is closed, the automobile door decorating part and the door threshold decorating part are mutually butted to realize the sealing between the door and the threshold.

At present, when sealing is carried out between an automobile door decorating part and an automobile threshold decorating part, sealing is usually carried out through arranging a sealing strip. The sealing structure of the vehicle door and the side wall comprises a vehicle door guard plate assembly, a threshold beam and a side wall outer plate matched with the vehicle door guard plate assembly, wherein the side wall outer plate is connected with the threshold beam and is coated on the outer side of the threshold beam, and the bottom of the vehicle door guard plate assembly is in sealing fit with the side wall outer plate through a sealing piece.

The above-mentioned scheme sets up three sealing strips, and the setting of sealing strip can lead to the structure to become complicated, can increase assembly process and manufacturing cost when production, is unfavorable for the environmental protection moreover, is unfavorable for lightweight and reduce cost's demand.

Disclosure of Invention

The utility model aims to provide an automobile door decoration, an automobile door decoration and a mutual matching structure thereof, which are used for solving the problem that the structure is complex and the production cost is high because a plurality of sealing strips are required to be arranged when a door decoration plate, a side wall outer plate and a threshold beam are sealed in the prior art.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides an automobile door decoration, includes the door decoration body, still be equipped with on the door decoration body with the automobile door bottom towards the outside lateral wall fixed connection's of car first connection structure, the bottom of door decoration body is equipped with the butt joint plane.

The utility model discloses in, the butt joint plane is arranged in with car threshold decoration butt joint, as long as set up on car threshold decoration with butt joint plane complex structure and make clearance fit between the two for when closing the door, door decoration and threshold decoration can realize sealedly. Because the moving direction is usually rotated around the hinge when the automobile door is opened and closed, only a small part of the automobile moves forwards and backwards, in order to avoid interference between the door trim body and the threshold trim, the butt plane is arranged at the lowest part of the door trim body, namely the door trim body can be arranged at the lowest part of the automobile door, so that the door trim body replaces part of the structure of the bottom of the automobile door, and the weight and the cost of the automobile door are reduced. The threshold decoration only needs to be provided with an upward surface which can be matched with the bottom surface of the threshold decoration, and the two surfaces are in clearance fit, so that the butt joint of a butt joint plane and the threshold decoration of an automobile can be realized after the automobile door is closed, and the matching clearance of the two surfaces is preferably as small as possible. Meanwhile, even if the vehicle door slightly sinks or deforms under the influence of gravity or other factors, the matching can be realized, and the height of the butt joint plane can be increased as much as possible because the butt joint plane is positioned at the bottommost surface of the vehicle door, so that the height of the joint of the two surfaces is increased, the water on the road surface is not easy to contact, and the possibility of water inflow is further reduced.

Further, the first connecting structure comprises a first mounting buckle arranged on the upper portion of the door trim body, and the first mounting buckle is arranged on one side face, facing the side wall of the automobile, of the trim body.

The upper portion of door decoration body sets up first installation buckle and is connected with the car door bottom, be equipped with the mounting hole on the side wall planking of car door with first installation buckle is connected, and the lower part of car door is less than the bottommost of car door promptly, then the lower part structure of door decoration body has replaced the structure of door, and door decoration generally uses light material such as plastics to make, has alleviateed the weight of door like this and has reduced manufacturing cost.

Further, at least two different heights of the upper part of the door decoration body are provided with first mounting buckles.
