Description

Touch pen with magnetic induction roller and its operation method

The present invention provides a stylus with a magnetic induction scroll wheel and an operation method thereof, especially a stylus that can operate the rotary scroll wheel to browse the screen page of a preset electronic device. The rotary scroll wheel and a magnetic induction element are assembled in the accommodating space inside the penholder , For the two detection points on the magnetic sensor element and the magnetic element on the central axis of the rotating wheel to form magnetic induction, so as to achieve the purpose of controlling the preset electronic device through the stylus at the lower end of the penholder.

According to the continuous advancement of electronic technology, in addition to electronic and electrical products for indoor operation and application, portable electronic devices (such as laptops, tablets or smart phones) are more convenient for carrying applications. It has become the most widely used electronic product in recent years. It has not only won the favor of young generations, but also popular in various generations such as teenagers, middle-aged, and old people. It has almost reached the level of human hands, especially tablet computers or smart phones. Portable electronic devices such as portable electronic devices are even more popular regardless of age. In the current social environment, people with lowered heads and long-term operation and use of portable electronic devices are often seen. However, most of the screens of portable electronic devices are touch-sensitive. For controlled operation applications, you must use your finger or stylus to slide and touch on the screen to browse and change pages on the screen. However, the user’s finger has a larger touch area on the screen of the electronic device. , When performing operations such as sliding, tapping, etc., often sliding several pages at a time, unable to accurately control the page to browse or change pages, so that the user must often repeat up and down Only then can you find the page you want to browse, which creates inconvenience in operating the screen of the electronic device.

And some electronic devices are equipped with a smart stylus for the screen, which allows users to use the tip of the smart stylus to touch the screen of the electronic device for control. Nowadays, the smart stylus tends to be multifunctional. The design of the smart stylus requires more control elements to be added. The purpose is to allow the user to move the cursor position arbitrarily or change the operation mode of the window screen in real time. However, increasing the number of control elements will gradually complicate the relationship between the elements in the stylus mechanism, and the final result will be reflected in the volume change of the smart stylus.

The current smart stylus used in electronic devices seems to be easy to find that the thickness and size of the pen body of many styles of stylus are too large and difficult to hold compared to the pen body used for normal writing. When the pen body tends to be designed with more functions, the larger the pen body is, the more difficult it is to hold. This is because the left and right mouse buttons in desktop computer applications, the middle scroll wheel that moves up and down the window, the power switch key, and the window shortcut keys If all of the various components are to be assembled on the thin body of the smart stylus, the volume of the smart stylus will naturally change. Furthermore, if you observe the influence of the above components on the volume change, the scroll wheel system accounts for the largest change in the volume of the stylus pen body. The reason is that it is relative to the left mouse button, right mouse button, power switch key, and window shortcut keys. For the components that are activated or deactivated by the signal, the middle mouse wheel is responsible for the up and down movement of the window screen. The pen body usually involves more gears, signal sensors and effect modules and other components. So overall , The scroll wheel system affects the most critical person for the volume of the pen body.

In addition, if the conventional technology develops a design scheme that exposes the outer edge of the roller to the pen body from the inside of the pen body, for example, the Chinese Mainland Patent Publication No. CN205334393U discloses a pen-shaped wireless mouse. Please refer to the first picture. The pen body shell From bottom to top, the left mouse button A, the right mouse button B, the scroll wheel C, and the switch D are arranged in sequence from bottom to top, but the scroll wheel C is adjacent to the left mouse button A, The right button B is located at the position of the index finger of the user holding the stylus. According to the user's habit, the index finger of the hand is usually less conducive to force rotation of the scroll wheel than the thumb. Therefore, this design solution has room for improvement in the operability of the user interface. Furthermore, each sensor inside the pen body uses optical sensor E for detection, so it relies on more battery F energy consumption.

In addition, in order to develop a more user-friendly operability, conventional techniques such as the Republic of China Patent Publication No. 201530370, disclosed that the outer part of the pen body uses the rotation of the rotating sleeve to replace the original purpose of pressing the function key, so as to reduce the user's accidental touch function. Key probability. This kind of design scheme is to change the control of the on or off state through the change of the electrical signal in each control section inside the rotating sleeve. This inventive concept can be described as an innovative move. However, the conduction or disconnection relies on the direct contact between the conductive elastic body and the pen body to switch between different input signals, and the design freedom of this internal mechanism still leaves much room for improvement. How the latecomers apply the innovative ideas of the rotating sleeve and further solve the other unsolved problems of the smart stylus are problems that the latecomers urgently need to think about.

Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, evaluated and considered from many parties, and based on the accumulated years of experience in this industry, through continuous trials and modifications, he designed this kind of touch with magnetic induction roller. Stylus and its operation method; the stylus of the present invention uses the advantages of the prior art related to the concept of rotating sleeve and is further improved to a magnetic coupling sensing method, which solves the problem that the stylus has to move up and down in order to control the window screen. The volume problem of installing too many components in the internal mechanism avoids excessive changes in the size of the pen body, so that the user can more easily hold and operate the stylus pen freely.

Please refer to Figures 3, 4, 5, 6, 7 and 8, which are the three-dimensional exploded view, side sectional view, schematic diagram of the magnetic induction method between the magnetic element and the magnetic induction element of the present invention, and the second detection point of the magnetic sensor A schematic diagram of detecting angular momentum changes, a partial three-dimensional appearance diagram of a preferred embodiment, and a flow chart of manipulation steps. The rotating roller 2 is provided with a ring-shaped magnetic element 22 on the central axis 21 above or below the through hole 101 of the penholder 1 , And relative to the magnetic element 22, a magnetic induction element 3 is provided on the inner wall surface of the accommodating space 10 of the penholder 1, and the magnetic element 22 is a ring-shaped magnet, including at least two opposite S magnetic poles 221 and N magnetic poles 222; and the magnetic induction The element 3 can be a Hall sensor 31, and the magnetic element 2 can be detected through two magnetic sensing detection points 31a, 31b located at the same diagonal position or at different corners.

The operation method of controlling the operation of the preset electronic device 4 through the touch pen, the steps are:

(A01) Part of the circumference of the rotating roller 2 exposed at the through hole 101 of the penholder 1 is for the user to operate and rotate the rotating roller 2 with one hand.

(A02) As for the magnetic element 22 on the central axis 21 of the rotating roller 2, the angular momentum or angular velocity of the magnetic field lines of the two different magnetic poles of the S magnetic pole 221 and the N magnetic pole 222 will change.

(A03) The two detection points 31a and 31b of the magnetic induction element 3 detect the changes in the magnetic field lines generated by the S magnetic pole 221 and the N magnetic pole 222 of the magnetic element 22, and the magnetic induction element 3 is converted into the rotating roller 2 every time it rotates. Offset signal per unit time.

(A04) The offset signal per unit time is transmitted to the circuit board 32 with a wireless signal module, and the wireless signal is transmitted by wireless transmission through the wireless signal module (such as Bluetooth or RF wireless signal transmitter unit) To the preset electronic device 4.

(A05) The built-in wireless signal receiving unit (such as Bluetooth or RF) of the preset electronic device 4 receives the wireless signal, and then transmits the wireless signal to the built-in processing unit of the preset electronic device 4 (such as OS System or signal processor, etc.).

Because the accommodating space 10 of the penholder 1 assembles the rotating roller 2 and the magnetic induction element 3, the magnetic element 22 of the rotating roller 2 and the two detection points 31a, 31b of the magnetic induction element 3 form a magnetic induction coupling state through rotational displacement. There is no need to supply power through the power supply, and the magnetic induction coupling between the magnetic element 22 and the two detection points 31a, 31b of the magnetic induction element 3 will not be affected by insufficient power of the power supply, and no magnetic induction coupling will be interrupted. , Pause, delay, or termination, etc., and the magnetic induction coupling can be performed smoothly, and the screen 41 of the preset electronic device 4 can be controlled to smoothly slide, change pages, or browse.

Please refer to Figures 3, 4, and 9 which are a perspective exploded view, a side sectional view, and a perspective exploded view of another embodiment of the present invention. It can be clearly seen from the figures that the present invention has a magnetic induction roller The stylus is attached to the central shaft 21 of the rotating roller 2 assembled in the accommodating space 10 of the penholder 1, and at least one gear 24 is inserted through it. The gear 24 is arranged on the inner wall of the accommodating space 10 of the two rod bodies 11 There is at least one shrapnel 241, which can be used to rotate the gear 24 when the rotating roller 2 is rotated, and the gear 24 will touch the at least one shrapnel 241 to generate a sound or feedback; in addition, the central shaft 21 of the roller 2 can be rotated The upper sleeve is provided with at least one bearing 25, and the outer circumference of the at least one bearing 25 is against the inner wall surface of the accommodating space 10 inside the penholder 1, so that the central shaft 21 of the rotating roller 2 in the accommodating space 10 receives at least A bearing 25 is firmly supported, and when the rotating roller 2 rotates with the central shaft 21, it is not easy to cause unstable defects such as shaking and offset.

In general, the stylus with a magnetic induction scroll wheel of the present invention detects the angular momentum of the magnetic field lines of the S magnetic pole 221 and N magnetic pole 222 of the magnetic element 22 through the two detection points 31a and 31b of the magnetic induction element 3 Change or angular velocity change, etc., and then The screen 41 of the preset electronic device 4 can be precisely controlled to move (up or down, left or right, etc.), and has the following advantages:

(1) The volume change of the penholder 1 is effectively reduced. The internal accommodating space 10 of the penholder 1 has a small number of assembling elements, and only has a rotating roller 2 and a magnetic induction element 3. The assembly operation is also more convenient, time-saving and labor-saving.

(2) The annular magnetic element 22 on the central axis 21 of the rotating roller 2 is detected by the two detection points 31a, 31b of the magnetic induction element 3 located on the inner wall surface of the accommodating space 10 of the penholder 1, forming a non-contact Rotating magnetic flux coupling sensing, instead of the conventional mechanical contact operation mode, the two detection points 31a, 31b on the magnetic sensing element 3 have better sensitivity to the sensing detection signal of the magnetic element 22.

(3) The accommodating space 10 of the penholder 1 assembles the rotating roller 2, a magnetic induction element 3, and does not need to be powered by a power supply (such as a battery), then the S magnetic pole 221 of the magnetic element 22 on the central axis 21 of the rotating roller 2 The magnetic flux density generated by the N magnetic pole 222 will not be affected by insufficient power supply, that is, the magnetic induction coupling delay phenomenon between the two detection points 31a, 31b on the magnetic induction element 3 and the magnetic element 22 will not occur, so as to avoid operating presets The display screen 41 of the electronic device 4 is delayed, paused, or terminated.

The so-called simple modification and equivalent structural changes in the description and drawings of the present invention have various embodiments. Please refer to Figures 10 and 11 respectively. As long as the mechanism design can tilt the chip to make the two detection points 31a, 31b can be maintained on the same plane as the ring-shaped magnet, or the diagonals of the two detection points 31a, 31b are directly perpendicular to the central axis 21 or maintained at a specific angle, so that the magnetic sensor 3 can detect the rotation caused by the If the angular momentum or angular velocity of the magnetic field lines is changed, the magnetic element 22 and the magnetic induction element 3 can be transformed Position also belongs to the scope of the present invention.

According to the tenth figure, the stylus with a magnetic induction roller of the present invention includes a penholder 1, a rotating roller 2 and a magnetic induction element 3. The rotating roller 2 is replaced by a hollow roller or a sleeve-shaped roller. , So that the central shaft 21 can still extend outward from the two ends of the roller respectively, but the magnetic element 22 is no longer arranged on either side of the central shaft 21. Compared with the foregoing embodiments, the magnetic element 22 changes its position and is attached to the inner wall of the rotating roller 2. The magnetic element 22 is preferably in the shape of a ring magnet, and the magnetic induction element 3 is located in the inner hollow space of the rotating roller 2. Inside and on the central axis 21 of the penholder 1, the magnetic sensing element 3 is a Hall sensor 31, where, taking the IQS624 chip as an example, the two detection points 31a, 31b are still maintained on the same two-dimensional plane as the ring magnet, or The diagonals of the positions of the two detection points 31a and 31b are directly perpendicular to the central axis 21. When the rotating roller 2 rotates, the magnetic element 22 will rotate around the central axis 21, so that the magnetic sensor 3 can detect the angular momentum or angular velocity change caused by the rotation of the magnetic element 22, thereby controlling the movement of the window screen.

Moreover, according to the eleventh figure, the rotating roller 2 is also a hollow roller or a sleeve-shaped roller, and the magnetic induction element 3 is also a Hall sensor 31 and takes the IQS624 chip as an example, but the magnetic induction element 3 is changed again position. The Hall sensor 31 is no longer located in the inner hollow space of the rotating roller 2, or the central shaft 21, or the inner wall of the penholder 1, but is instead arranged on a circuit board perpendicular to the central shaft 21 and located adjacent to the ring magnet. This mechanism design makes the two detection points 31a, 31b and the ring magnet maintain the same two-dimensional plane, or the diagonals of the two detection points 31a, 31b are directly perpendicular to the central axis 21. Therefore, when the rotating roller 2 rotates, the magnetic induction element 3 also rotates, so that the angular momentum or angular velocity change of the magnetic element 22 is also detected, and then the control vision is achieved.
