Problems solved by technology

However, in order to form a specific turning angle, the stylus needs to be provided with a large number of parts including grooves, ratchets, balls, etc. Although the stylus with the above structure can solve the problem of the support of the portable device, its structure is complicated, and it is expensive to process. High, difficult to implement

Embodiment 1

[0014] Please refer to Figure 1 to Figure 4 , this embodiment includes a portable device body 1 and a stylus 2 . The front of this portable device body 1 has a panel with handwriting function, and the opposite side of the panel has a small hole 12, and its top surface is provided with a cylindrical cavity 11, and the stylus 2 is put into the cavity when it is not in use. 11 for easy portability.

[0015] The barrel of the stylus 2 is composed of two parts, an outer tube 21 and an inner tube 22, the first end of the outer tube 21 is used to connect and support the portable device 1, and the second end of the outer tube 21 is provided with cavity; the first end of the inner tube 22 is used to be fixed on a plane, and the second end of the inner tube 22 is pivotally mounted in the cavity of the outer tube 21 . In this example, if Figure 4 , the cavity at the second end of the outer tube 21 is provided with an internal thread 211, and the second end of the inner tube 22 is pr...

Embodiment 2

[0017] Compared with the previous embodiment, the difference is that in this embodiment, the inner tube and the outer tube of the pen tube of the stylus are not threaded, and the second end of the outer tube of the stylus in this embodiment is connected to the inner tube. The second end of the tube is made of elastic material, such as rubber, plastic or fiber. The cavity at the second end of the outer tube is in interference fit with the outer diameter of the second end of the inner tube. According to the elastic modulus of the material , The interference fit of the interference fit can be 0~0.005mm. The stylus of this embodiment uses the friction of the pen tube itself to control the length of the inner tube of the stylus included in the outer tube, and can achieve the purpose of adjusting the tilt angle of the screen of the portable device without any other accessories or auxiliary mechanisms.

Abstract

The invention discloses a handwriting pen applied to a portable device, which comprises an outer tube, an inner tube, and a pair of connecting devices, wherein a first end part of the outer tube is used for connecting and supporting the portable device and a second end part thereof is provided with a cavity; a first end part of the inner tube is used to be fixed to a plane and a second end part thereof is pivoted in the cavity of the outer tube; and the pair of connecting devices is arranged in the cavity of the outer tube and on the second end part of the inner tube, and can adjust the lengthof the second end part of the inner tube extending into the cavity of the outer tube, so the portable device has different gradients relative to the plane. The handwriting pen realizes the functionswhich can be realized by complicated parts in the prior art through fewer parts and simple structure, saves cost and facilitates industrial popularization.

Description

technical field [0001] The invention relates to a portable device and its stylus, in particular to a structure in which the stylus can be used as a supporting frame of the portable device. Background technique [0002] With the development of the electronic communication industry, portable devices such as mobile communication terminals and PDAs (Personal Digital Assistants) have more and more functions, integrating online email sending and receiving, stock information browsing, e-book browsing, electronic games, and database applications. , wireless communication and multimedia playback and other functions. In order to facilitate manipulation, some portable devices have a handwriting input function, and users can input corresponding information in the handwriting input area through a stylus, which is convenient and fast. When users use such portable devices to watch video materials such as movies and MTV, they need to tilt the portable devices to achieve the best viewing ef...
