Description

Bonding structures for electronic devices

technical field

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

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.

In addition to the solution of fixing the two housings with screws, other electronic devices currently on the market simply use hooks, sliding structures, or Velcro to assemble and fix the housings. 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.

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.

As for the fixing method of the Velcro, it is necessary to provide a Velcro of a large enough size to provide sufficient adhesive force for fixing, which also affects the available internal space of the electronic device. Moreover, 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.
