The outer covering parts of the automobile, such as a fender, a bonnet, a trunk lid, a door, a side wall, a top cover, glass and the like, are easy to have assembly gaps, poor assembly surfaces and the like, so that the assembly accuracy and the aesthetic property of the automobile are low. In the related art, taking a fender as an example, in order to ensure the assembly precision of the fender, one implementation manner is as follows: by increasing the level of manufacturing process, however, there is still some deviation in the quality and design of the parts according to the current state of the art, and in addition, from a cost standpoint, it is often necessary to give the parts a certain tolerance to ensure the part yield. Another implementation is: in the related art, for example, when a plurality of parts are assembled, two adjacent parts are often assembled in the same direction, for example, two adjacent parts are assembled in a horizontal direction or two adjacent parts are assembled in a vertical direction. However, the assembly errors of the components in the same direction are accumulated greatly, the error accumulation cannot be weakened well, and further the final assembly position of the fender is easily changed greatly, so that the assembly precision of the fender is low and the attractiveness is poor.

Aiming at the technical problems, the embodiment of the application provides an automobile. The automobile of the present application may refer to a large automobile, a small automobile, a dedicated automobile, and the like. The automobiles in the present application may be, for example, passenger cars, off-road cars, multi-Purpose Vehicles (MPV) or other types, depending on the type of the automobile.

In automobiles, there are generally provided wheels, a power source, and a transmission system provided between the wheels and the power source, wherein the transmission system is capable of transmitting power provided by the power source to the wheels to rotate the wheels, thereby driving the vehicle.

In addition, in the embodiment of the present application, the type of the power source of the automobile is not limited. For example, for a fuel-powered automobile, the power source may refer to a fuel engine such as a gasoline engine, a diesel engine, or the like; for an electric vehicle, the power source may be referred to as an electric motor; for a hybrid electric vehicle, the power source may refer to an engine or an electric motor; for an otherwise powered vehicle, the power source may refer to a device that generates power. )

The automobile provided by the embodiment of the application comprises a vehicle body and a lap joint device 100 besides the wheels and the power source, wherein the lap joint device 100 comprises a wheel cover 110, a cabin side beam assembly 120 and a fender assembly 130. The vehicle body includes a housing main shell on which the wheels are assembled, the housing main shell includes a housing body on which the fender 132 of the fender assembly 130 is assembled, and the assembled fender 132 and the housing body together form the housing main shell. That is, the fender 132 forms a part of the total shell of the outer shell of the automobile, and it is understood that the color and material of the fender 132 are substantially the same as those of the total shell of the outer shell.

The wheel cover 110 is located above the wheel, wherein the wheel cover 110 is an ornament on the outside of the wheel. The fender is an outer panel of a vehicle body covering a wheel, and has the effect of protecting the wheel and blocking mud like a protective shell because the shape and position of the fender are named as a bird wing. The fender can be divided into a front fender and a rear fender according to the installation position, the front fender is installed at the front wheel, and the rear fender is installed at the rear wheel.

The effect of the fender is that the sand and mud rolled up by the wheels can be prevented from splashing to the bottom of the vehicle body during the running process of the vehicle, so that the materials used for the fender must have weather aging resistance and good molding processability. Some fenders are made of plastic materials with certain elasticity, the strength of the plastic materials is low, the injury to pedestrians is small when the automobile collides, the pedestrian protection performance of the automobile is improved, and the automobile can bear certain elastic deformation and resist slight collision.

During assembly, the first overlapping surface 124 of the side sill assembly 120 and the overlapping surface 113 of the wheel cover overlap in the first direction, the first overlapping surface 124 is attached to the overlapping surface 113 of the wheel cover, the second overlapping surface 125 of the side sill assembly 120 and the overlapping surface 133 of the fender assembly overlap in the second direction, and the second overlapping surface 125 is attached to the overlapping surface 133 of the fender assembly.

By attaching the first landing surface 124 to the landing surface 113 of the wheel cover, the second landing surface 125 is attached to the landing surface 133 of the fender assembly. Therefore, when the cabin side beam assembly 120 and the wheel cover 110, the cabin side beam assembly 120 and the fender assembly 130 are tightly pressed and fixed by the connecting pieces, the possibility that gaps appear on the installation surfaces of the cabin side beam assembly 120 and the wheel cover 110 and the installation surfaces of the cabin side beam assembly 120 and the fender assembly 130 can be reduced, so that the cabin side beam assembly 120 is tightly attached to the wheel cover 110 and the fender assembly 130, and the use experience of a user is improved.
