Problems solved by technology

However, due to the high cost of its design and manufacture, it is usually only used in high-end cars and other products, and it cannot be widely used at all.
[0004] In fact, there has been a technical bias in the industry for a long time regarding this problem, believing that there is no low-cost technical solution other than adopting complex process technology and investing more funds to solve it
As a result, the formation of gaps visible to the naked eye between the mating surfaces of components has become a ubiquitous and commonplace phenomenon, and has become a problem that has long been hoped to be solved but has not been effectively solved.

Embodiment Construction

[0050] Figure 1a and Figure 1bThey are respectively a front view and a rear view of the assembled assembly of the name plate and decorative cover embodiment of the structure of the present invention. As shown, the plate 2 as the second part is mounted on the back side (i.e. the non-appearance surface) of the decorative cover 1 as the first part, both of which can be made of hard materials such as plastics, copper, aluminum, etc. A good assembly appearance effect can be formed by adopting the matching installation method shown in the figure.

[0051] then please go to Figure 2a , 2b , 3a and 3b, the characteristics of the structure of the present invention can be further understood by referring to these figures in conjunction. Wherein, the matching installation surface between the decoration cover 1 and the plate 2 includes the fitting surface 3 that is compatible with each other and the clearance fitting surface 4 that is fitting with each other, and such fitting surface...

Abstract

The invention discloses a structure for the fit installation among components, wherein the fit installation surfaces among the components comprise assembly surfaces (3) which are mutually adaptive and gap fit surfaces (4) which are mutually adaptive; the assembly surfaces (3) and the gap fit surfaces (4) form a stairway shape; and assembly gaps are formed among the gap fit surfaces (4) of the components, thus the gap distances among the assembly surfaces (3) of the components are zero after fit installation. The structure disclosed by the invention can eliminate the defect of visual gaps generated in the course of the fit installation among the components, thereby guaranteeing the quality of fit gaps and the uniformity of surface differences.

Description

【Technical field】 [0001] The invention relates to a cooperating installation structure between components, in particular to a structure for adopting rear stepped coordinating installation between hard components, which belongs to the technical field of mechanical structures. 【Background technique】 [0002] In the prior art, people can cooperate and install several components together to form an assembly according to actual needs, so as to facilitate its application. Of course, due to various reasons, the mutual cooperation effect between these components may not be all satisfactory. For example, if you pay a little attention, you will find that there are generally gaps visible to the naked eye between the mating surfaces of the common trims in the car models currently on the market. The main reason is that decorative parts made of hard materials such as plastics and aluminum sheets have rounded corners at the matching positions of the corners, which will cause different deg...
