Description

Stylus pen, control method thereof, and electronic device component

Technical Field

The present invention relates to the technical field of stylus pens, and in particular to a stylus pen and a control method thereof, and an electronic device component including the stylus pen.

Background technique

As an increasingly popular peripheral input device, a stylus pen has begun to be widely used. However, a stylus pen in a conventional technical solution generally has only a basic handwriting function. If an erasing function is required, it needs to be implemented through an undo operation.

Some styluses also realize the erasing function by operating on the display screen of a touch-controlled electronic device (such as a mobile phone or tablet computer) to switch the working state of the stylus tip. However, since both erasing and normal writing operations are completed through the stylus tip, when it is necessary to frequently switch between erasing and writing, the user needs to continuously click on the corresponding icon on the display screen of the touch-controlled electronic device (such as a mobile phone or tablet computer), which brings inconvenience to the user and greatly reduces work efficiency.

Summary of the invention

A first aspect of an embodiment of the present application provides a stylus pen, the stylus pen comprising:

A housing having a hollow accommodating cavity, a first opening at a first end, and a second opening at a second end opposite to the first end;

A pressing component is disposed in the accommodating cavity, and one end of the pressing component extends out of the first opening;

A stylus tip is disposed in the housing and can be partially extended from the second opening or retracted into the housing under the drive of the pressing assembly;

a touch electrode, disposed on an end surface of the second end of the housing and isolated from the stylus tip; and

The controller is disposed in the housing and is electrically connected to the stylus tip and the touch electrode.

In a second aspect, an embodiment of the present application provides a control method for a stylus, the control method comprising:

Detecting the extension and retraction state of the stylus tip relative to the housing;

When the stylus tip is extended out of the housing, controlling the touch electrode to be closed;

When the stylus tip is completely retracted into the shell, the touch electrode is controlled to be turned on.

In a third aspect, an embodiment of the present application provides an electronic device component, which includes an electronic device and the stylus described in the above embodiment; the electronic device can be communicatively connected with the stylus, and the stylus can perform writing, touching and erasing operations on the touch display screen of the electronic device.

The stylus provided in the embodiment of the present application has a structure of a touch electrode at the end position of the shell for extending the stylus tip, and uses a pressing component to drive the stylus tip to extend or retract into the shell. When the stylus tip is extended from the shell, the stylus tip can cooperate with the touch screen of an external device to realize functions such as writing and touching; when the stylus tip is retracted into the shell, the touch electrode can cooperate with the touch screen of an external device to realize an erasing function. Compared with the stylus structure in the traditional solution, the stylus in the embodiment of the present application has the feature of convenient switching between the erasing function and the handwriting function, which greatly improves the user experience of using the stylus.

Please refer to Figures 3 to 5 together. Figure 3 is a structural schematic diagram of a state in which the stylus tip of an embodiment of the stylus pen of the present application is retracted into the shell, Figure 4 is a structural schematic diagram of a state in which the stylus tip of the stylus pen in the embodiment of Figure 3 is extended out of the shell, and Figure 5 is a structural cross-sectional schematic diagram of the stylus pen along line A-A in the embodiment of Figure 4. The stylus pen in this embodiment includes but is not limited to the following structures: a shell 110, a pressing component 120, a stylus tip 130, a controller 140 and a touch electrode 150.

Specifically, the housing 110 has a hollow accommodating cavity 1100, and two opposite ends are respectively a first end and a second end, and the first end and the second end are respectively provided with a first opening 111 and a second opening 112. The pressing component 120 is arranged in the accommodating cavity 1100, and one end extends out of the first opening 111; the stylus tip 130 is arranged in the housing 110, and a part of the structure can extend from the second opening 112 or retract into the housing 110 under the drive of the pressing component 120; the controller 140 is arranged in the housing 110, and is electrically connected to the stylus tip 130; the touch electrode 150 is arranged at the second end of the housing 110, and is isolated from the stylus tip 130, and the touch electrode 150 is also electrically connected to the controller 140.

Optionally, the touch electrode 150 in this embodiment can be specifically disposed on the end surface of the second opening 112. The touch electrode 150 is made of a material that can trigger the touch screen, such as a metal that can change the capacitance of the touch screen. The controller 140 is used to control the working state of the stylus tip 130 and the touch electrode 150 and to send and receive communication signals with the electronic device 200.

When the stylus tip 130 is retracted in the housing 110 (the state in FIG. 3 ), the touch electrode 150 can cooperate with the touch screen of the external device (referring to FIG. 1 , for example, the touch display screen 210 of the electronic device 200 ) to realize the erasing function. When the user needs to write with the stylus tip 130, the user can drive the stylus tip 130 to extend out of the housing by pressing the component 120, and then the user can use the writing, touch and other operations of the stylus tip 130.

Please continue to refer to Figures 4 and 5. In this embodiment, one end of the housing 110 where the second opening 112 is provided is a conical structure, the second opening 112 is provided at the end of the conical structure, and the touch electrode 150 is provided at the end surface of the second opening 112. Optionally, the touch electrode 150 in this embodiment may be a ring-shaped structure, and is provided at the end surface of the second opening 112. This design structure of the touch electrode 150 can facilitate the use of the touch electrode 150.

Optionally, please continue to refer to FIG. 5 . The pressing assembly 120 in this embodiment includes a pressing portion 121, a transmission member 122, and a spring 123. Among them, one end of the pressing portion 121 extends out of the first opening 111 of the housing 110, and the other end is connected to the transmission member 122. The transmission member 122 abuts against the non-touch end of the stylus tip 130. The spring 123 is sleeved on the circumference of the stylus tip 130 located in the internal structure of the housing 110, and is used to provide an elastic force for the stylus tip 130 to retract into the housing 110. Among them, the structure of the transmission member 122 may specifically include a pressure rod, a locking member, and other structures (not specifically indicated in the figure). The upper part of the pressure rod is connected to the pressing portion 121, and the lower locking member is rotatable. Only the tooth tip of the pressure rod and the locking member are partially engaged. After engagement, the guide ribs of the two members slide in the same guide groove (which may be provided on the inner side wall of the housing, not shown in the figure). When the user presses the pressing portion 121 with a finger, the pressing rod moves along the slide groove to press the locking member to move downward. When the pressing rod is disengaged from the engagement portion of the locking member, due to the action of the spring 123, the locking member will rotate an angle and slide to the other side, and the stylus tip 130 will extend out of the second opening 112 of the housing 110. Repeating this process can achieve the function of extending and retracting the stylus tip 130 into the housing. Among them, the detailed structure and working principle of the transmission member 122 can refer to the currently common press-type ballpoint pen structure. The detailed structural features of this part are within the understanding of those skilled in the art and will not be repeated here.

In addition, in some other embodiments, the pressing component 120 may also be in other structural forms, as long as it can drive the stylus tip 130 to extend or retract into the housing, and no specific limitation is made here.

Optionally, please continue to refer to FIG. 5 . The stylus in this embodiment is further provided with a sensor 160 in its housing 110. The sensor 160 is electrically connected to the controller 140. The sensor 160 is used to detect the extension state of the stylus tip 130. Specifically, the extension state of the stylus tip 130 can be indirectly detected by detecting the position of the pressing portion 121. Of course, in some other embodiments, the sensor can directly detect the extension state of the stylus tip (for example, the sensor 160 is an optical sensor that directly detects the moving position of the stylus tip 130). The detailed structural features of this part are within the scope of understanding of those skilled in the art and will not be described in detail here.

To save power consumption, only one of the stylus tip 130 and the touch electrode 150 can be in working state at the same time. They can be switched by detecting the position state (pressed state) of the pressing part 121 through the sensor 160. This method can also effectively avoid accidental touches. For example, when the user needs to turn off the stylus tip 130, the pressing part 121 can be long pressed, or it can be automatically turned off when it has not been in contact with the touch display screen of the electronic device for a long time. When the user needs to use the stylus tip 130, press the pressing part 121 to trigger wake-up.

Optionally, in order to prevent interference between the touch electrode 150 and the stylus tip 130, the touch electrode 150 and the stylus tip 130 send different signal frequencies when triggered externally. Alternatively, the problem can be solved by presenting different sensing effects at one end of the touch display screen 210 of the electronic device 200, which is not specifically limited here.

In addition, the stylus in the embodiment of the present application may further include structural features such as a battery 170 and a gravity sensor 180 electrically connected to the controller 140, wherein the battery 170 supplies power to the stylus, and the gravity sensor 180 is used to detect the cutting angle of the stylus. The detailed technical features of this part are within the scope of understanding of those skilled in the art and will not be repeated here.

The stylus provided in the embodiment of the present application has a structure of a touch electrode at the end position of the shell for extending the stylus tip, and uses a pressing component to drive the stylus tip to extend or retract into the shell. When the stylus tip is extended from the shell, the stylus tip can cooperate with the touch screen of an external device to realize functions such as writing and touching; when the stylus tip is retracted into the shell, the touch electrode can cooperate with the touch screen of an external device to realize an erasing function. Compared with the stylus structure in the traditional solution, the stylus in the embodiment of the present application has the feature of convenient switching between the erasing function and the handwriting function, which greatly improves the user experience of using the stylus.

Optionally, the present application also provides a method for controlling a stylus pen. Please refer to FIG6 , which is a flowchart of an embodiment of the method for controlling a stylus pen of the present application. The control method in the present embodiment is based on the structure of the stylus pen in the above-mentioned embodiment. The control method includes but is not limited to the following steps:

Step S100, detecting the extension and retraction state of the stylus tip relative to the housing.

Please continue to refer to FIG. 5 . In this step, the position state of the pressing component 120 (the pressing portion 121 ) can be detected by the sensor 160 . The extended state of the stylus tip relative to the housing 110 can be determined by detecting the position state of the pressing component 120 .

Please continue to refer to FIG. 6 . The control method in this embodiment further includes step S200 , in which the touch electrode is controlled to be turned off when the stylus tip is extended out of the housing.

In this step, the touch electrodes 150 may be powered off by the controller 140 .

Please continue to refer to FIG. 6 . The control method in this embodiment further includes step S300 , in which the touch electrode is controlled to be turned on when the stylus tip is completely retracted into the housing.

In this step, the touch electrodes may be energized to restore them to a working state.

The control method of the stylus in the embodiment of the present application controls the opening and closing of the touch electrode by detecting the extended state of the stylus tip relative to the shell, so that one of the stylus tip and the touch electrode is in a working state, thereby achieving the purpose of reducing energy consumption and thereby increasing the use time of the stylus.

Please refer to FIG. 7 , which is a flow chart of another embodiment of the control method of the stylus of the present application. The control method in this embodiment includes but is not limited to the following steps:

Step S100, detecting the extension and retraction state of the stylus tip relative to the housing.

Step S200 , when the stylus tip is extended out of the housing, controlling the touch electrode to be closed.

Step S300, when the stylus tip is completely retracted into the housing, controlling the touch electrode to be turned on.

Among them, for the detailed features of steps S100 to S300, please refer to the relevant description of the aforementioned embodiment. The difference between this embodiment and the aforementioned embodiment is that the control method in this embodiment also includes step S400, which controls the closing of the stylus tip when the stylus tip is fully retracted into the shell.

In this step, the stylus tip may be powered off or its touch function may be turned off to reduce energy consumption.

Please continue to refer to FIG. 7 . The control method in this embodiment further includes step S500 , detecting the duration of time during which the touch electrodes are continuously not triggered.

This step may be specifically completed by a timer in the controller 140 .

Please continue to refer to FIG. 7 . The control method in this embodiment further includes step S600 , when the time length for which the touch electrode is continuously not triggered is greater than a preset time length, controlling to turn off the touch electrode.

The control method of the stylus in this embodiment can further reduce energy consumption by controlling the stylus tip to be closed when the stylus tip is fully retracted into the shell and controlling the touch electrode to be closed when the touch electrode has not been triggered continuously for longer than a preset time.

The above descriptions are only some embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any equivalent device or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
