Stylus pop-up mechanism

The present invention relates to an ejection mechanism, and more particularly to an ejection mechanism for a stylus.

With the development of technology, mobile electronic devices such as mobile phones and personal digital assistants (PDAs) have gradually become important tools for people to conduct information management, especially the advancement and wide application of touch technology. Many portable electronic devices have a stylus provided to facilitate quick input of information by the user.

In order to make the stylus easy to pick and place, one method is to set the pen slot on the side wall of the casing of the portable electronic device, and the friction between the stylus pen and the pen slot prevents the stylus from coming loose from the pen slot. The above structure is relatively simple, but it is difficult to access; the other method is that the stylus pen tip (touch screen end) retains the barb slot fixing, and when the stylus is fixed in the portable electronic device, it can be carried by finger swiping. The control button on the electronic device causes the hook to be disengaged from the stylus and the stylus is pushed out by the elastic member. For example, a stylus pop-up switch device is mounted in a portable electronic device housing. The stylus is provided with a first holding portion, and the housing is provided with a sliding elastic action portion and an elastic ejection member. The elastic action part is provided with an action switch, and the elastic ejector element is provided with a second holding part; the ejecting switch device is provided with an elastic clamping part for clamping the stylus; the elastic clamping part is fixed in the housing The action switch is disposed inside and outside the clamping portion; the second holding portion clamps and fixes the first holding portion. When the action switch is worn in the bullet When the clamping portion is outside, the elastic clamping portion and the elastic ejection member are in a compressed state, and the stylus is stuck in the elastic ejection member; when the stylus needs to be taken out, the action switch is toggled, and the action switch is worn. The elastic clamping portion is disposed in the elastic clamping portion to elastically open the elastic clamping portion, and the second clamping portion is elastically stretched to cause the stylus to eject the housing under the elastic force. However, the stylus pop-up switch must cooperate with the elastic actuation portion to engage the stylus in the housing, and the structure is complicated.

In view of this, it is necessary to provide a stylus ejection mechanism having a simple structure.

A stylus ejection mechanism includes a housing, an elastic operating element mounted in the housing, and an elastic ejection member for ejecting the stylus, the elastic operating element including a pressable device disposed in the housing An operating member and an elastic member for holding the operating member, the operating member is provided with a sliding slot through which the stylus passes, the elastic member abuts the operating member, and the stylus is locked in the housing by the sliding slot And the elastic ejection member is opposite to the stylus by pressing the operation member, and the elastic ejection member ejects the stylus.

Compared with the prior art, the stylus ejection mechanism of the present invention fixes the stylus in the housing by the operation member, and ejects the stylus by pressing the operation member and the elastic ejection member. The stylus ejection mechanism has a simple structure.
