Background

The back door of an automobile is generally positioned by a hinge located above the back door and a lock centered at the lower end of the back door, and in order to provide good cushioning when the back door is closed, a cushion pad is usually provided at each of the left and right sides of the lower end of the back door.

The backdoor cushion only provides a supporting force, and plays a role in limiting the X direction and the Z direction when the backdoor is closed. In the driving process of the vehicle, because the area and the weight of the backdoor are large, Y-direction (left-right direction) shaking (particularly bumping the road surface) is easy to occur, so that the backdoor collides with the side wall of the vehicle body or the rear combination lamp, and even air drum sound, lock impact sound and the like are generated. Therefore, people set limit devices on the left and right sides of the backdoor, and the limit devices usually consist of a backdoor limiter installed on the backdoor and a vehicle body limiter installed on a vehicle body. When the backdoor is closed, the left backdoor limiter, the right backdoor limiter and the two vehicle body limiters are in matched contact with each other, so that the backdoor is limited in the Y direction.

However, the existing back door limiting structure has the following problems: first, stop device and buffer separate the setting, make whole structure too complicated, be not convenient for installation and maintenance. Secondly, because the manufacturing assembly precision problem of car, the interference volume when stop device location inclined plane contacts is inconsistent, and the interference volume undersize, limiting displacement is limited and produce the abnormal sound easily, and the interference volume is too big, probably leads to the backdoor can't close and sound too big when opening. And thirdly, the limiting device usually adopts a surface-to-surface fit limiting structure, so that the back door can be limited in one or two directions generally, the comprehensive limitation in X, Y, Z three directions is difficult to realize, and the limiting precision is low.

Detailed Description

Example the utility model discloses an assembly and use

As shown in fig. 1 to 6, the automobile back door limiting structure comprises a vehicle side limiting structure and a back door side limiting structure which are respectively arranged on a vehicle body and a back door and are matched with each other;

the back door side limiting structure comprises a back door side limiting block 2; the vehicle body side limiting structure comprises a vehicle body side limiting block 1 and a metal framework 1-2 embedded in the vehicle body side limiting block 1; the limiting surfaces of the vehicle side limiting block 1 and the back door side limiting block 2 which are matched with each other are inclined planes.

Specifically, the vehicle body side limiting surface 1-1 of the vehicle body side limiting block 1 is perpendicular to the XY plane of the vehicle body and arranged at an included angle of 35-50 degrees with the ZX plane to guide the back door and limit the back door in the X, Y direction.

Specifically, the material of car body side stopper 1 is soft in the material of back of the body side stopper 2, and the back of the body is closed the back, and back of the body side stopper is sunken in the certain degree of depth in car body side stopper, carries out Z to spacingly to the back of the body.

Specifically, the back door side limiting block 2 is made of plastic.

The vehicle body side limiting block 1 is made of composite rubber.

As shown in fig. 5 and 6, a vehicle body side stopper surface 1-1 of the vehicle body side stopper 1 has a hollow structure; the back door side limiting surface 2-1 of the back door side limiting block 2 is a smooth surface.

As shown in fig. 4, bolt guide holes 1-3 are specifically formed in the vehicle body side limiting block 1 and the back door side limiting block 2; the bolt pretension of back of the body door and automobile body can be well guided, and the installation is convenient.

As shown in figure 1 and figure 2, in the use and the assembly process, the two limiting surfaces of the back door side limiting block and the vehicle body side limiting block are matched with each other, the buffering and limiting effects are achieved, the metal framework is located in the vehicle body side limiting block, the reinforcing effect is achieved, and the problem that the bolt is crushed due to the fact that the vehicle body side limiting block is soft partially is avoided. Glue is smeared on the surface of the metal framework, so that the metal framework is fixed in the limiting block on the side of the vehicle body and does not move.

As shown in fig. 4, when the back door is closed, the back door side limiting block and the vehicle body side limiting block are close to each other, the back door side limiting block enters the limiting surface of the vehicle body side limiting block under the guidance of the limiting surface, the limiting surface is perpendicular to the XY plane of the vehicle body and forms a certain included angle with the ZX plane, and therefore, component forces are generated in the X direction and the Y direction by pressure when the two limiting surfaces are matched with each other, and the limiting effect in the X, Y direction is achieved. After the back of the body door is closed completely, back of the body door side stopper and car body side stopper match completely, because back of the body door side stopper adopts the higher plastics material of intensity, car body side stopper adopts the lower rubber material of intensity, consequently, car body side stopper takes place to warp during the matching, sink into certain degree of depth in the spacing face of car body side stopper in the spacing face of back of the body door side stopper, car body stopper can produce the component force of a Z direction to back of the body door side Z to spacing face 2-2 this moment, to back of the body door Z to playing limiting displacement, simultaneously because car body side stopper 1 has fine elasticity, can also play the effect of buffering to the back of the body door.
