Description

Stylus

The present invention relates to a stylus, and more particularly to a stylus with a button feel.

With the development of mobile communication technologies, touch-screen portable electronic devices are increasingly favored by users.

The stylus is the main way for the touch screen type portable electronic device to input information. The conventional stylus is usually a simple pressing lever, and the user directly presses the touch screen on the touch screen of the touch screen type electronic device.

However, the stylus is harder to use when used, and it does not allow the user to perceive the force of pressing, so that the user is bound to exert excessive force and damage the touch screen.

In view of this, it is necessary to provide a stylus with a button feel.

A stylus pen includes a head, a tip, an elastic element and a body, the pen head being mounted at one end of the pen body, the pen tip being telescopically received in the pen body, and one end of which is exposed to the pen body The elastic member is received in the pen body, and one end thereof abuts against the pen tip and the other end abuts against the pen tip.

Compared with the prior art, the stylus makes the user feel the button feel by the deformation of the elastic component, and can sense the strength of pressing the touch screen, thereby better changing the shortcoming of the conventional stylus feel.

Referring to FIG. 1 , a preferred embodiment of the stylus with a button feel of the present invention is used for inputting a message of a portable electronic device, which includes a head 21 , a spring 22 , a buffer body 23 , A tip 24 and a body 25. The pen tip 24, the buffer body 23 and the elastic piece 22 are sequentially accommodated in the pen body 25, and are attached to one end of the pen body 25 by the pen head 21.

Referring to FIGS. 2 to 4 together, the longitudinal cross section of the pen head 21 is substantially in the shape of a "T", which is formed by connecting a first cylindrical body 211 having a smaller diameter to a second cylindrical body 212 having a larger diameter. Thus, a resisting surface 213 is formed at the joint. A circular groove 214 is defined in an end surface of the first cylinder 211 away from the second cylinder 212 for receiving the elastic piece 22 therein. The material of the writing head 21 is plastic, such as Acrylonitrile Butadiene Styrene (ABS) or Polycarbonate (PC).

The elastic piece 22 is a spherical elastic piece body having a convex surface 221 and a concave surface 222 opposite to each other. The elastic piece 22 can be accommodated in the recess 214 in such a manner that the convex surface 221 faces the writing head 21, or the concave surface 222 can be received in the recess 214 in such a manner as to face the writing head 21.

The buffer body 23 is a cylinder having a through hole 231 formed through the two end faces. The material of the buffer body 23 is rubber or the like, which is disposed between the pen tip 24 and the elastic piece 22 for buffering the force of the pen tip 25 pressing against the elastic piece 22. In addition, the buffer body 23 also serves to fill the assembly gap, preventing the writing of the writing head 21, the elastic piece 22 and the pen tip 24.

The nib 24 includes a head portion 241, a tail portion 242 connected to one end of the head portion 241, and a pressing portion 243 protruding from the other end of the head portion 241. The head 241 is a cylinder. The tail portion 242 is a solid table body, and one of the larger end faces is connected to one end of the head portion 241 and forms a resisting surface 244. The pressing portion 243 is a cylindrical body whose diameter is substantially equal to the diameter of the through hole 231 of the buffer body 23 so as to be received in the through hole 231. The material of the nib 24 is plastic, such as Acrylonitrile Butadiene Styrene (ABS) or Polycarbonate (PC).

The pen body 25 includes a hollow truncated cone 251 and a hollow cylinder 252 fixed to one of the larger end faces of the truncated cone 251. The hollow cylinder 252 defines a receiving hole 253 having a circular cross section through its two end faces. The size of the receiving hole 253 is substantially equal to the size of the first cylinder 211 of the pen head 21. The hollow truncated cone 251 defines a tapered hole 254 communicating with the receiving hole 253 through the two end faces. The size of the tapered hole 254 is smaller than the size of the receiving hole 253, thereby forming a resisting surface 255 therebetween. The abutting surface 255 is for resisting the abutting surface 244 of the pen tip 24. The taper of the tapered bore 254 is substantially equivalent to the taper of the outer surface of the tail portion 242 of the nib 24 to more closely receive the nib 24 therein. The material of the pen body 25 is plastic, such as Acrylonitrile Butadiene Styrene (ABS) or Polycarbonate (PC).

Referring to FIG. 1 and FIG. 3 , when the stylus pen 20 is assembled, the pen tip 24 is first inserted into the receiving hole 253 of the pen body 25 with the tail portion 242 facing the pen body 25 , thereby further accommodating the tail portion 242 of the pen tip 24 . The tapered hole 254 is partially exposed outside the pen body 25 by the tapered hole 254. At this time, the head portion 241 of the pen tip 24 is received in the receiving hole 253 of the pen body 25; then the buffer body 23 is placed in the pen body 25 The accommodating hole 253 is received in the end surface 241 of the pen tip 24, and the pressing portion 243 of the pen tip 24 is received in the through hole 231; then the elastic piece 22 is received in the recess 214 of the pen head 21, The pen tip 21 with the elastic piece 22 is inserted into the receiving hole 253 of the pen body 25 with the groove 214 facing the pen body 25; then the pen head 21 is continuously pushed until the abutting surface 213 of the pen head 21 abuts against the pen body 25 The end surface of the resisting surface 244 is abutted against the resisting surface 255. At this time, the first cylindrical body 211 of the writing head 21 is in interference fit with the receiving hole 253 of the pen body 25, and the pen tip 24, the buffer body 23 and the elastic piece 22 are used. It is firmly housed in the pen body 25, thus completing the assembly of the stylus pen 20.

When the stylus 20 is used for message input, the user can hold the pen head 21 or the pen body 25, and press the touch screen by the pen tip 24 of the stylus pen 20. When the pressing force reaches the desired value, the pressing force is counteracted. The force will cause the pressing portion 243 of the pen tip 24 to press the elastic piece 22 until the pressing portion 243 abuts against the end of the pen tip 21. At this time, the user will feel the feel of pressing a certain keyboard button, thereby being well perceived. Press the strength of the touch screen to avoid damage to the touch screen due to excessive pressure.

It can be understood that the first cylinder 211 can be locked in the receiving hole 253 of the pen body 25 by screwing or bonding.

It can be understood that the elastic piece 22 can also be replaced by an elastic member such as a compression spring.

The stylus 20 is deformed by a spring piece 22 to make the user feel the button feel, and can sense the strength of pressing the touch screen, thereby better changing the shortcoming of the conventional stylus feel.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
