Description

Magnetic rotation sensor endless scroll wheel stylus

This creation is to provide a magnetic rotation induction endless scroll wheel stylus, especially a stylus that can operate the rotary scroll wheel to browse the screen of the preset electronic device. The ring-shaped magnetic element is assembled on the ring groove on the outer surface of the penholder, and the inner volume is A magnetic induction element is assembled in the set space for the two detection points on the magnetic induction element and the ring-shaped magnetic element to form magnetic induction, so as to achieve the purpose of controlling the preset electronic device through the touch pen tip on the side of the pen barrel.

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 smartphones, etc.) 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 the young generation, but also popular in various generations such as teenagers, middle-aged, and old people. It has almost reached the level of a human hand, 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 low 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 fingers 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., several pages are often swiped at a time, and the page cannot be accurately controlled 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.

Some electronic devices are equipped with a smart stylus for the screen, which can be used by the user to touch the screen of the electronic device with the tip of the smart stylus. 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, because the left and right buttons of the mouse on the desktop computer applications, the middle scroll wheel that moves up and down the window, the power switch key, and the window shortcut key 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. Further, 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 scroll wheel of the mouse 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 of the pen body volume.

In addition, if the conventional art has developed 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 Figure 1 for 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 and right button B and is located The position of the index finger of the user holding the stylus pen is usually less conducive to force rotation of the scroll wheel than the thumb of the hand according to the user's habit. Therefore, this design has room for improvement in the operability of the user interface. Furthermore, the sensors inside the pen body use optical sensors E for detection, so it relies on more battery F energy consumption.

In addition, in order to develop more user-friendly operability, conventional techniques such as the Republic of China Patent Publication No. 201530370 disclose that the rotation of the rotating sleeve is used to replace the original purpose of pressing the function key to reduce the user's accidental touch function. Key probability. The idea of this design scheme is to control the on or off state by changing the electrical signal in each control section inside the rotating sleeve. This creative idea 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 by the latecomers. 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 need to think urgently.

Therefore, in view of the above-mentioned problems and deficiencies, the creators 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, they began to design this magnetic rotation induction stepless Numerous scroll wheel stylus, this creative stylus uses the advantages of the known skills 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.
