Combination structure for electronic apparatus

Abstract

The invention provides a combination structure for an electronic apparatus. The combination structure comprises fixed clamping parts, movable limiting parts and limiting grooves, wherein the fixed clamping parts have a clamping direction in a first direction; the movable limiting parts and the limiting grooves have a clamping direction in a second direction which is opposite to the first direction; and the movable limiting parts can move back and forth slightly on a first body in the second direction under the effect of an elastic part. When the first body is combined to a second body in the mounting direction, the fixed clamping parts can the buckled mutually in the first direction; meanwhile, after the movable limiting parts are aligned to the corresponding limiting grooves, the limiting parts and the limiting grooves are buckled mutually in the second direction under the push of the elastic part; and in addition, the limiting parts with ferromagnetism can be additionally applied with magnetic attractive force to separate from the clamping state with the limiting grooves, so as to separate the first body from the second body.

Description

technical field [0001] The invention relates to a combination structure, in particular to a composite snap-fit ​​structure used for fixed and movable combination of electronic devices. Background technique [0002] At present, regarding the assembly of electronic devices such as notebook computers, mobile phones, desktop computers, etc., it is necessary to add screws between the casings or between an additional cover and the casing to prevent the casing from being separated or parts from falling off. This traditional screw locking method often uses a large number of screws, which increases the assembly man-hours and makes it inconvenient for users to disassemble and assemble by themselves. In order to meet the development trend of light, thin, and simple electronic devices, too many screws will affect the integrity and aesthetics of the device itself, and the screws will be lost during disassembly and assembly, and the screws are prone to chipping. [0003] In addition to t...

Problems solved by technology

However, just like screw fixing has its disadvantages, using hooks to fix the shell can easily cause structural breakage or deformation during the disassembly process, and in order to reinforce the fixing structure such as hooks, it is necessary to increase the structural space, or even Causes disassembly and assembly procedures that are more difficult for the production line or users

[0004] Using the sliding structure to fix the shell, a large sliding space must be reserved for the sliding structure in the structural design, and the sliding structure still needs to use other fixing means to maintain the parts at a specific position to avoid the parts from slipping loose, so the sliding structure cannot achieve the purpose of directly replacing screw fixing

[0005] As for the fixing method of the Velcro, it is necessary to set a large enough Velcro to provide the adhesive force required for fixing, which also affects the available internal space of the electronic device.

And the current Velcro fixing scheme must be added with other auxiliary structures to pass the test of bonding strength, which cannot meet the current thin and light needs of notebook computers
