Telescopic stylus and portable electronic device with the same

The present invention relates to a stylus and a portable electronic device with the stylus, and more particularly to a telescopic stylus and a portable electronic device with the retractable stylus.

With the development of communication technology, the telescopic stylus not only adapts to the development trend of the light and thin touch-type portable electronic devices, but also meets the user's comfortable and convenient use requirements.

Referring to FIG. 1 , a conventional telescopic stylus 10 can be disposed in the receiving slot 31 of a portable electronic device 30 . The telescopic stylus 10 includes a tube 11 , a sleeve 12 and a resisting member 13 disposed on the sleeve 12 . An elastic member 111 is disposed inside the pen tube 11. The sleeve 12 is telescopically sleeved inside the pen tube 11 and abuts against the elastic member 111. The resisting member 13 has a biasing portion 131 and a latching portion 132. The urging portion 131 is for taking out the telescopic stylus 10. The catching portion 132 is for holding the telescopic stylus 10 in the housing groove 31. The material of the pen tube 11 and the sleeve 12 is stainless steel.

When the telescopic stylus 10 is housed in the portable electronic device 30, the pen tube 11 is simply inserted into the accommodating slot 31 of the portable electronic device 30, and the sleeve 12 is compressed by the elastic member 111. In the inside of the pen tube 11, at this time, the holding portion 132 is held in the housing groove 31, and the telescopic stylus 10 is prevented from coming off the portable electronic device 30 by frictional force.

When the telescopic stylus 10 is taken out from the portable electronic device 30, an external force is applied, which is greater than the gap between the holding portion 132 and the groove wall of the receiving groove 31. The frictional force releases the resisting member 13 from the receiving groove 31. At this time, the elastic member 111 pushes the barrel 11 out of the sleeve 12 by its elastic force so that the user can take out the telescopic stylus 10.

However, the structure of the telescopic stylus 10 is relatively complicated, and there are many components, which requires a lot of manufacturing process and production cost, and the material of the pen tube 11 and the sleeve 12 of the telescopic stylus 10 is relatively expensive. The high-grade stainless steel further increases the production cost of the telescopic stylus 10. In addition, the stainless steel stylus 10 is bound to have a certain negative impact on the antenna performance of the portable electronic device 30.

In view of this, it is necessary to provide a retractable stylus with a simple structure.

It is also necessary to provide a portable electronic device with the telescopic stylus.
