Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automotive interior, specifically relates to a simple and easy magnetic quick-release structure for automotive interior. BACKGROUND

[0002] With the rapid development of the automobile industry, consumers' requirements for automobile configuration are increasing, and automobile configuration gradually develops towards high-end and intelligence, among which the proportion of electronic parts in automobile configuration is increasing. Electronic parts bring more functions and convenience to automobiles, but due to their complexity and sensitivity, the failure rate is relatively high. When electronic parts fail, the interior parts often need to be frequently disassembled in order to repair or replace electronic components.

[0003] At present, the conventional automotive interior structure mainly adopts two ways of fixing with clips and fixing with screws. However, these two traditional fixing methods have obvious limitations. On the one hand, during the disassembly and assembly process, the clips and screws are prone to wear, deformation and other conditions, and generally can only be disassembled and assembled 5 times without damage, which cannot meet the emerging needs of frequent disassembly and assembly of interior parts due to electronic component maintenance; on the other hand, the interior parts that need to be disassembled use screw or buckle fastening, which not only has a traditional form, but also exposes the matching structure after disassembly, greatly affecting the overall aesthetics of the automotive interior and reducing the user experience.

[0004] In the application of magnets to automotive interior fixation, the existing technical solutions also have many problems: at present, the main way is to use the opposite attraction of magnets, which requires the use of a large number of magnets, resulting in high cost and being unable to comply with the current industry trend of reducing costs; in addition, some interior parts embed magnets as auxiliary installation points, but due to the high temperature resistance requirement of the insert injection molding process for magnets, the cost of magnets that meet this requirement is extremely high, which seriously limits the large-scale application of magnets in automotive interiors; at the same time, due to the characteristics of magnets that repel each other and attract each other, the current magnet structure must be designed to prevent mistakes to prevent the fastening point from failing due to repulsion, which makes the magnet structure not fully universal, increasing the complexity of design and production.

[0005] Therefore, there is an urgent need for a simple and easy magnetic quick-release structure for automotive interior. UTILITY MODEL CONTENT
