Description

Handheld device

The present invention relates to a hand-held device, and more particularly to a space-saving handheld device.

Currently, hand-held devices such as personal digital assistants (PDAs) and mobile phones use batteries as their energy source. The existing hand-held device battery is mostly a detachable battery, and is accommodated in a hand-held device, and a battery cover that is inserted into the body of the casing is disposed thereon. When you need to replace the battery, open the battery cover and remove the battery.

Referring to Figure 4, a conventional battery cover structure is disclosed. The battery 40 is mounted to the rear of the mobile phone body 50, and a locking device for locking the battery 40 is mounted within the body 50. The locking device includes a hook 60 mounted at a rear portion of the body 50 to be movable up and down, a spring 68 mounted between the hook 60 and the body 50, and a locking groove 42 formed at one end of the battery 40 and used for The hook 60 is locked. The hook 60 includes a manipulation portion 62 that protrudes outwardly; a spring mounting portion 64; and a locking projection 66 for locking the hook 60 into the locking groove 42 of the battery 40. During installation, the battery 40 is pressed toward the body 50, and the hook 60 is moved toward the front end of the body 50 under the pushing of the battery 40. When the battery 40 is placed in the body 50, the hook 60 slides backwards under the push of the spring 68. The locking projection 66 is inserted into the locking groove 42 of the battery 40 such that the battery 40 is fixed within the body 50. A disadvantage of this configuration is that it requires a space for mounting the locking device on the mobile phone body 50, thereby reducing the space availability of the mobile phone body 50.

In view of this, it is desirable to provide a handheld device that saves space on the body.
