Description

Automobile front protection and grille connecting device and automobile Technical Field The invention belongs to the technical field of automobiles, and particularly relates to an automobile front protection and grille connecting device and an automobile. Background When the front protector and the grille are separated to be arranged on the assembly line, the front protector and the grille are limited by the modeling style of the grille and the assembly beat of the assembly line, the grille is required to be conveniently and easily arranged in the front protector in terms of assembly maintainability, and is convenient and quick to detach, but the grille cannot be separated from the front protector under the condition of limited use of the whole vehicle in terms of reliability, so that the two requirements are contradictory and difficult to be compatible. In coping with such conflicting performance requirements, only reliability requirements can be met. The convenience of assembly takt and after-sales maintenance of the assembly line cannot be considered, for example, the assembly takt is suffered in the refitting trend of the off-road vehicle type. And the modeling style, such as cutting a screw or bolt blanking cover on the modeling appearance surface, is needed to be used for shielding the screws or bolts after the front protection is connected with the grid screws or bolts, so that the screws or bolts are prevented from being exposed, the modeling consistency is possibly damaged, and the single-piece cost, the assembly time and the after-sales maintenance cost of the parts are increased. Disclosure of Invention The invention provides a connecting device for a front guard and a grille of an automobile, which aims to solve the problems that the consistency of modeling is destroyed, the cost of a single part of a part is increased, and the assembly time and the after-sale maintenance cost of the assembly of the front guard and the grille of the automobile are increased. In order to achieve the above purpose, the invention adopts the following technical scheme: the invention provides a connecting device for front protection and grille of an automobile, which comprises a grille assembly and a front protection assembly, wherein: The grille assembly and the front protection assembly are of non-integrated assembly structures, a plurality of connecting structures are arranged between the grille assembly and the front protection assembly, and the connecting structures comprise a first release structure and a second release structure; the first release structure comprises a clamping angle arranged on the grid assembly and a clamping hole arranged on the front protection assembly, the clamping angle and the clamping hole are connected in a clamping manner through an adapting mode, the second release structure comprises a clamping jaw structure arranged on the grid assembly, a standard part assembled on the clamping jaw structure and a passing clamping hole arranged on the front protection assembly, the standard part and the passing clamping hole are connected in a clamping manner through the adapting mode, a difference area of the first release structure and the second release structure is arranged in a minimized mode, and a plurality of connecting structures can be switched and combined freely through changing a die insert and a checking fixture module. In some embodiments, the clamping angle is a 7-shaped clamping angle, the 7-shaped clamping angle is integrally formed on the grid assembly, the clamping hole is a front-protection assembly duck-tongue-shaped clamping hole formed in the front-protection assembly, and the 7-shaped clamping angle is clamped in the front-protection assembly duck-tongue-shaped clamping hole according to the front-to-back assembly direction so as to form limit clamping fit.
