Brush stylus with rotating telescopic structure

The present invention relates to a brush stylus with a rotating telescopic structure, and particularly relates to a brush stylus structure which protects a writing head from being damaged by external force and being twisted and deformed.

With the maturity and intuitive use of touch-screen technology, today's touch screens have long been an indispensable input interface for handheld devices. Users only need to touch the screen to achieve pointing or input effects. It is used in today's mobile phones, cameras and even computer products.

According to the different sensing principle, the touch screen can be divided into two types: resistive and capacitive. The most sensitive one is resistive. The resistive touch screen mainly generates the corresponding sensing signal according to the resistance change. In other words, any object that touches the surface of the screen will produce a change in resistance, that is, a corresponding sensing signal is generated. This resistive touch screen is very sensitive, but it is easy to be accidentally touched by clothes or surrounding objects during the carrying process. The malfunction occurs; the so-called capacitive touch screen mainly uses the current change to generate the sensing signal. In short, a small current change is required to generate the corresponding sensing signal, and the user generates a small current by using the human body in addition to the finger touch. In addition to the corresponding sensing signal, the conductive material can also be used to generate the corresponding sensing signal. Therefore, the touch pen is smaller than the finger. The front end of the touch pen has a conductive material tip (not shown), which can be Corresponding sensing signals are generated in a small area, so that users can have limited Write or touch within the range.

However, although the stylus described above generates a sensing signal in a small area, the material of the conductive material is often too hard, and the touch screen is easily crushed by the writing head due to improper application. The industry has developed a soft use. As a pen tip (as shown in Figure 1), the conductive rubber can solve the above-mentioned defects, but it is found that the friction between the soft conductive rubber and the screen is too large, which makes the user feel very laborious when writing and touching, and the touch effect is also Insensitive, it has developed a conductive brush as an inductive tip (as shown in Figure 2). The sensor is softer than the conductive rubber except for the soft rubber. It can effectively solve the above various types of touch pens. problem.

However, the above-mentioned touch pen using the conductive brush as the inductive pen head can solve any touch problem encountered by the current touch pen, but it is necessary to additionally use a pen cover or a protective cover to protect the conductive brush, otherwise it is easy Due to improper carrying or improper storage, the pen tip is deformed or depilated, but the user often loses the pen cover or the protective cover, which causes the touch pen tip to lose protection and is easily deformed and damaged.

Therefore, how to effectively maintain the life of the touch pen with the conductive brush tip, and to facilitate carrying and storing, and the deformation of the pen head is a subject of research and development.

The main purpose of the present invention is to provide a brush stylus with a rotating telescopic structure, which uses a forward rotation and a reverse rotation to control the tip of the pen to extend or retract into the body. The brush stylus includes: a brush-type pen head and a body And a telescopic rod body, wherein the telescopic rod body is sleeved inside the body, the front end of the telescopic rod body is fixed integrally with the pen head, and the rear end of the telescopic rod body exposes the rear end of the body for the user to forward or reverse To the rotation control, when the rear end of the telescopic rod body rotates in the forward direction, the front end of the telescopic rod body pushes the tip to extend out of the body; when the rear end of the telescopic rod body rotates in the reverse direction, the front end of the telescopic rod body The tip of the pen is retracted into the interior of the body, thereby achieving protection against the deformation of the pen tip by external force.

According to the above main features, the telescopic rod body comprises at least: an inner rod body and an outer rod body, wherein the inner rod body is sleeved inside the outer rod body, wherein the pen head is disposed at the front end of the inner rod body, the outer rod body The rear end exposes the rear end of the body, and when the rear end of the outer rod body rotates forwardly, the outer rod body pushes the inner rod body forward to move the pen head out of the body, and when the rear end of the outer rod body is reversely rotated, the outer rod body pushes The inner rod moves backwards, causing the tip to retract into the body.

According to the above main feature, the rear end of the outer rod body is exposed at the rear end of the body, and further has a knob body with a larger outer diameter for the user to rotate in the forward or reverse direction.

According to the main features of the foregoing, the outer surface of the outer rod is provided with a spiral through groove, and the inner surface of the inner rod is correspondingly provided with at least one linking piece, and the connecting piece is located inside the spiral through slot, when the rear end of the outer rod is positive When rotating, the outer rod body spirally passes through the groove wall to push the inner rod linkage piece, so that the inner rod body moves forward, so that the pen tip protrudes outside the body, and when the outer rod rear end rotates backward, the outer rod The body spiral grooved groove wall pushes the inner rod body linkage piece to move the inner rod body backward, so that the pen head is retracted into the body.

The brush stylus described in the present application may also be referred to as a touch brush or a touch brush, which is mainly used on a capacitive touch screen, which will be described first.

Referring to FIG. 3, the present invention provides a brush stylus with a rotating telescopic structure. The present invention comprises: a head 10, a body 20 and a telescopic rod body 30; wherein the telescopic rod body 30 is sleeved on the body The front end of the telescopic rod body 30 is fixed for the writing head 10, and the rear end of the telescopic rod body 30 is exposed at the rear end of the body 20. In more detail, the writing head 10 is disposed at the front end of the telescopic rod body 30, and the front end of the writing head 10 The outer shape is formed by a plurality of conductive fiber bundles forming a shape similar to a brush head, and a rear end of the pen tip 10 has a metal sleeve for holding and fixing the conductive fiber hair.

In the embodiment, the body 20 is a hollow tube body for accommodating the pen head 10 and the telescopic rod body 30. The inner diameter of the body 20 needs to match the pen head 10 and the telescopic rod body 30; The telescopic rod body 30 includes at least an inner rod body 31 and an outer rod body 32. The inner rod body 31 is sleeved inside the outer rod body 32, and the pen tip 10 is disposed at the front end 310 of the inner rod body 31. The rear end 321 of the rod body 32 rotates forwardly, and the outer rod body 32 pushes the inner rod body 31 so that the pen head 10 protrudes out of the body 20 (as shown in FIG. 4). When the rear end 321 of the outer rod body 32 rotates in the reverse direction, The outer rod 32 pushes the inner rod 31 to retract the pen head 10 into the body 20 (as shown in Fig. 5); thereby, the pen tip 10 is extended or retracted into the body 20 by means of positive reversal, thereby protecting the pen head 10 It is not subject to external damage and is transformed.

In addition, the rear end 321 of the outer rod body 32 of the present invention is exposed to the body 20 and has a rotation. The button body 40 is for the user to rotate in the forward or reverse direction. The size of the knob body 40 depends on the overall shape of the body 20.
