Clamping mechanism and electronic device using the same

technical field

The present invention relates to a snap-fit mechanism and an electronic device using the snap-fit mechanism, in particular to a snap-fit mechanism that utilizes a collocation design of a pressing piece and a slider to easily remove an object and the application of the snap-in mechanism Electronic device of the integrated mechanism.

Background technique

With the development of the communication industry, the mobile phone industry is booming day by day, and fueled by the advertising media, the mobile phone has become an indispensable part of daily life. People use mobile phones to receive real-time information, communicate with the outside world or browse information online, which makes life more colorful.

Please refer to FIG. 1 , which shows a perspective view of a traditional mobile phone. The mobile phone 100 includes a battery 102 and a base 104 . The base 104 includes a groove 106 . The battery 102 is placed on the base 104 . When the user wants to take out the battery 102 , the user needs to pass through the groove 106 and use fingers and fingernails to pull the battery 102 away from the base 104 . However, if the user's fingers are thick or the nails are short, the battery 102 cannot be removed smoothly. Or although the battery 102 has been taken out, the user's fingers have been injured.

In addition, the battery 102 is placed in the base 104 , and the engagement between the battery 102 and the base 104 is not very tight, so that the electrical contacts between the battery 102 and the mobile phone 100 may be poorly connected. When the user lifts the back cover (not shown) of the mobile phone 100 , the battery 102 is often loosened, resulting in loss of the battery 102 . Moreover, if the mobile phone 100 is accidentally dropped and its back cover is opened, the battery 102 will be separated from the base 104 and the mobile phone will be turned off directly.

In addition to mobile phones and their batteries, many electronic devices and their components have the above-mentioned problems. For example, personal digital assistant (personal digital assistant, PDA), electronic dictionary or smart phone (Smart Phone) and its battery, expansion card and other objects.

Therefore, how to make it easier for the user to take out the battery. Furthermore, it is an important research goal in the current industry to make the battery and the base tightly engaged to reduce the occurrence of the battery being loose relative to the base.
