Description
Technical Field
[0001] The present invention belongs to the category of computer writing interaction technology in the field of electronic equipment control technology. In scenarios such as digital office, teaching and design, the demand for computer writing interaction is increasing, but existing technologies, such as traditional keyboard and mouse and touchpad handwriting solutions, have problems such as inaccurate recognition of "pen lifting" and "pen dropping" and unsmooth writing. The present invention aims to solve these pain points and provide an innovative solution for computer writing interaction. Background Art
[0002] With the rapid development of science and technology, electronic products have been deeply integrated into our daily lives. Computers play an important role in office, study, entertainment, etc. with their large screen display and powerful computing power. At present, the main device for controlling computers is the mouse. However, when it is necessary to write or draw in applications such as whiteboard software and image editing software, the mouse seems to be unable to do so.
[0003] Although the use of a laptop's built-in touchpad or an ordinary touchpad with a capacitive pen can achieve writing functions to a certain extent, there are still many problems. For example, when teachers use whiteboard software to teach, they need to frequently switch the "selected" state to write normally, which is cumbersome and seriously affects the teaching rhythm; when designers make fine drawings in image editing software, the "pen lifting" and "pen dropping" cannot be accurately conveyed to the computer, resulting in uneven lines and affecting the quality of the work. Moreover, the default "selected" operation of most current touchpads is to double-click the touchpad, which is very different from people's habit of writing on paper. The operation is extremely inconsistent, which greatly reduces the speed and quality of writing and drawing.
[0004] Although there are styluses on the market that can simulate the touch screen of a mobile phone or tablet on a computer, these styluses must rely on a matching touchpad to be used, and cannot work properly on the touchpad that comes with a laptop or an ordinary touchpad. This means that users need to purchase and carry a matching touchpad, which is very inconvenient to use and limits its application scenarios. Summary of the invention
[0005] In order to effectively solve the above technical problems, the present invention aims to provide a wireless mouse stylus pen to significantly improve the computer writing interaction experience and break through the existing technical bottleneck. Its core goal is to overcome the problem of uncoordinated operation in the existing human-computer interaction process, solve the problem that the stylus pen cannot accurately distinguish between "lifting the pen" and "putting the pen down" on the touchpad, and at the same time improve the writing fluency and operation convenience, and expand the application scenarios of computer writing interaction.
[0006] The technical solution adopted by the present invention is: a wireless touch pen for mouse, which is mainly composed of a pen body part, a touch part, a circuit board part, a battery part and a USB wireless receiver part.
[0007] The pen body is made of high-strength and lightweight engineering plastics, which ensures a stable structure while reducing the overall weight, making it easy to hold for a long time. The ergonomic design of the pen body is in line with the holding habits of human hands, and the surface is specially frosted to increase friction and effectively prevent slipping during use.
[0008] Touch part: includes the pen tip part and the finger control part. The pen tip part includes a ball, a pen tip, a spring, a transmission column, a pen tip switch and a fixing ring. The ball is made of wear-resistant and smooth ceramic material, which can roll stably on the surface of various touch panels and accurately transmit writing movements. The pen tip is made of special alloy material with high hardness and good wear resistance to ensure clear and smooth writing. The spring is made of highly elastic and fatigue-resistant stainless steel material, which can accurately sense pressure changes. The finger control part includes the roller, transmission shaft, gear, rolling sensor, roller switch, roller switch bracket and thumb key. The roller surface is designed with a unique texture to increase the friction between the finger and the roller, making the operation more precise. The transmission shaft is made of high-strength aluminum alloy to ensure structural strength while reducing weight.
[0009] Circuit board: It is composed of data line, wire and integrated circuit board. The integrated circuit board is the core control unit of the stylus pen, which adopts advanced low-power and high-performance chip. The chip integrates multiple functional modules such as signal processing and wireless communication, which can quickly and accurately process the signal from the touch part and convert it into computer-recognizable instructions through optimized algorithms. At the same time, a signal enhancement module is also set on the circuit board to effectively improve the stability and distance of wireless transmission and reduce signal interference.
[0010] Battery part: It consists of a storage battery and a charging interface. The storage battery uses a high-capacity, long-life lithium polymer battery. Compared with traditional lithium-ion batteries, it has a higher energy density and a longer cycle life. A single charge can meet the user's needs for more than 100 hours of continuous use. The charging interface uses a type-c interface and supports fast charging technology, which can replenish a large amount of power for the stylus in a short time.
[0011] USB wireless receiver part: It consists of a USB wireless receiver and its storage location. The USB wireless receiver uses a high-speed and stable wireless transmission protocol, such as Bluetooth 5.0 or 2.4GHz wireless technology, to ensure fast and accurate data transmission between the computer and the pen. The storage location is designed at the end of the pen, and it adopts a magnetic design, which is convenient for users to store and carry, and effectively avoid loss.
[0012] Inside the pen case, from the pen tip to the pen tail, the touch part, circuit board part, battery part, and wireless receiver part are arranged in sequence. The surface of the pen is designed with a roller and thumb key for easy operation. The unique structure of the touch part can accurately sense the user's writing movements and convert them into electrical signals. When the pen tip touches the touchpad, the rolling ball drives the pen tip to produce a slight displacement, the spring is squeezed or stretched, and then pushes or pulls the transmission column to trigger the pen tip switch, realizing accurate recognition of the "pen down" and "pen up" actions. The circuit board part is responsible for data transmission and processing. Through optimized circuit design and signal processing algorithms, it ensures stable signal transmission and reduces delays and misjudgments. The battery part provides continuous power support for the entire stylus to ensure stable operation of the device. The USB wireless receiver part realizes wireless connection with the computer, making operation more convenient and free, and getting rid of the constraints of cables.
[0013] Compared with the prior art, the wireless mouse stylus pen of the present invention has the following significant advantages: Greatly improved writing experience: The unique pen tip design and precise pressure sensing system make the writing lines smoother and more natural, which is highly similar to the experience of writing on paper media, and effectively solves the problem of unsmooth lines when writing with traditional mice and touchpads. According to actual tests, under the same writing content and speed, the smoothness of the lines written with this stylus pen is improved by at least 50%, and the writing error rate is reduced by at least 50%.
[0014] Enhanced ease of operation: The ergonomic pen body design and finger-controlled layout allow users to easily perform various operations without having to frequently switch operating modes. For example, when a teacher is using whiteboard software to teach, he or she can use the thumb to operate the scroll wheel and thumb key to quickly turn pages, make annotations, and other functions, which increases the operating efficiency by at least 50% compared to traditional methods.
[0015] Wide compatibility: This stylus pen can not only work normally on the touchpad that comes with the laptop, but is also compatible with most ordinary touchpads and third-party software on the market. There is no need to purchase additional supporting equipment, which greatly expands the application scenarios.
[0016] Excellent battery life: The high-capacity lithium polymer battery and efficient charging technology provide users with long-term use guarantee and reduce the trouble caused by insufficient power. According to tests, under normal usage frequency, the battery life of this stylus is more than twice that of similar products. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1: Basic structure and working principle The wireless mouse touch pen of the present invention is composed of a pen body, a touch part, a circuit board part, a battery part and a USB wireless receiver part. In the pen shell, from the pen head to the pen tail, there are a touch part 450, a circuit board part 30, a battery part 20 and a wireless receiver part 10. The surface of the pen has a roller 53 and a thumb key 51. The pen head cover 62, the pen tail cover 63 and the pen shell 61 of the pen body are all made of plastic material, which has the advantages of light weight, low cost, strong plasticity, etc., and is convenient for large-scale production.
[0027] The touch part 450 is composed of a pen head part 40 and a finger control part 50. The ball 41, pen tip 44, spring 43, transmission column 46, pen head switch 45 and fixing ring 42 of the pen head part 40 work together to realize the perception and signal transmission of the writing action; the roller 53, transmission shaft 56, gear 55, rolling sensor 54, roller switch 52, roller switch bracket 57 and thumb key 51 of the finger control part 50 provide users with a convenient operation method. For example, the roller operation can realize functions such as page scrolling, and the thumb key can be used to quickly trigger specific instructions.
[0028] Embodiment 2: Detailed structure and working principle of the pen tip In the pen tip part, a ball 41 is tightly embedded on the pen tip 44, and a fixing ring 42 is provided in the middle of the pen tip 44 to fix the position of the pen tip. One end of the transmission column 46 is pressed against the tail of the pen tip 44, and the other end is pressed against the button of the pen tip switch 45. The spring 43 is wound around the transmission column 46, one end of which is connected to the tail of the pen tip 44, and the other end is pressed against the shell of the pen tip switch 45.
[0029] When the hand applies force toward the touch panel, the pen tip 44 of the pen head part will be under pressure, and a part of it will enter the pen shell 61. At this time, the spring 43 is squeezed and compressed, and the pen tip 44 pushes the transmission column 46 to apply force to the pen tip switch 45, and the pen tip switch 45 is pressed. The pen tip switch 45 is connected to the wireless transmission module. When the switch is pressed, the wireless transmission module will send a "select" command to the wireless receiving module, and the cursor position on the computer will be selected. If the pen tip 44 moves from a stroke starting position to a stroke ending position on the touch panel, and the computer is in an application environment that supports writing, such as whiteboard software or image editing software, the trajectory of movement on the touch panel will be transmitted to the computer via wireless signals and reflected on the computer screen, simulating the process of writing and writing when a person writes with a pen.
[0030] When the hand applies force in the opposite direction to the touch panel, the spring 43 will stretch, and the part of the pen tip 44 that has just retracted will extend out of the pen housing 61. The pen tip 44 pulls the transmission column 46 away from the pen switch 45, and the pen switch 45 is released. At this time, the wireless transmission module stops sending the "select" command to the wireless receiving module, and the cursor position on the computer returns to normal. If the pen tip 44 moves from the end position of a stroke to the start position of a stroke on the touch panel, and the computer is in the above application environment, the trajectory of the movement on the touch panel will not be reflected on the computer. The whole process simulates the process of a person lifting the pen and moving it to the start position of the next stroke when writing with a pen.
[0031] Embodiment 3: Detailed structure and working principle of the finger control part The finger control part 50 includes a roller 53, a transmission shaft 56, a gear 55, a rolling sensor 54, a roller switch 52, a roller switch bracket 57 and a thumb key 51. The angle between two perpendicular lines formed by connecting the geometric center of the roller 53 and the geometric center of the thumb key 51 to the center of the ball 41 and the geometric center of the USB connector in the wireless receiver 12 is 60°. This design conforms to the principle of ergonomics and is convenient for users to easily operate the roller and thumb key with their thumbs while holding the pen.
[0032] The transmission shaft 56 passes through the center of the circle of the two side walls of the roller 53. The transmission shaft 56 is fixed to the pen shell 61 at only one end, and the other end is movable. A gear set 55 is installed on the fixed end, and a rolling sensor 54 is installed on the pen belly. When the roller 53 rotates, the transmission shaft 56 rotates accordingly, driving the gear set 55 to rotate. The gear set 55 interacts with the rolling sensor 54 to convert the rotation signal of the roller into an electrical signal, which is transmitted to the computer through the circuit board part to realize functions such as page scrolling. A roller button 52 is set at the unfixed end, and its button is on the transmission shaft 56. When the user presses the roller 53, the roller 53 drives the roller shaft 56 to apply pressure to the roller switch 52, and the roller switch 52 is triggered, thereby realizing the function of the roller button. This design cleverly combines the roller button with the roller, which not only saves space but also makes the operation more convenient.
[0033] Example 4: Detailed structure and working principle of the circuit board and battery The circuit board part 30 is composed of a data line 32, an electric wire 33, and an integrated circuit board 31. The electric wire 33 and the data line 32 run through the entire pen. The electric wire 33 is responsible for connecting the electrical devices of the entire pen (such as the sensor of the touch part, the integrated circuit board, etc.) with the battery 21 to provide a stable power supply; the data line 32 is responsible for connecting the touch part 450, the integrated circuit board 31 and the wireless receiver storage position 11 to achieve data transmission and processing.
[0034] The integrated circuit board 31 is completely made of the circuit board of the wireless mouse. Due to the size limitation of the stylus pen, its layout may need to be adjusted in actual application. At the same time, in order to ensure that the current in the circuit is stable at about 3V, a step-down module needs to be installed on the integrated circuit board 31. The step-down module can stably step down the voltage output by the battery, ensure the normal operation of each electronic component, and improve the stability and reliability of the device.
[0035] The battery part 20 is composed of a storage battery 21 and a charging interface 22. The storage battery is a 3.7V lithium-ion battery, which has the advantages of high energy density and long cycle life, and can provide long-lasting power support for the stylus. The storage battery 21 is connected to the integrated circuit board 31 to power the entire stylus. The charging interface adopts a type-c interface, and a 5V to 4.2V step-down module is installed at the type-c interface. When an external power supply (such as a mobile phone charger) is used to charge the stylus through the type-c interface, the step-down module converts the 5V input voltage to 4.2V, and charges the storage battery 21 safely and stably to prevent damage to the battery caused by overcharging.
[0036] Example 5: Detailed structure and working principle of the USB wireless receiver The USB wireless receiver part 10 is composed of a USB wireless receiver 12 and a storage position 11 thereof.
[0037] There is a USB port at the end of the pen. While storing the USB wireless receiver, it can detect whether the USB wireless receiver is inserted to determine whether the user is using the product, thereby instructing the system to turn on and off. Figure 8 , the positive and negative USB interfaces on the battery are connected, and two metal balls are installed in any one of the four metal sheets corresponding to the USB wireless receiver, so that when the USB wireless receiver is inserted into this interface, the two balls can contact the same metal sheet of the USB wireless receiver at the same time, and the positive line connected from the battery is connected to one of the small balls, and the positive interface of the insertion sense is connected to the other small ball. The negative line is connected to the negative interface of the insertion sensing module, and the insertion sensing module is essentially a module that senses whether there is electricity. When it feels that it can receive electricity, it will issue a shutdown command to the system, and it will shut down itself 3 seconds after issuing the command. If the user directly shuts down through the power switch, it will also shut down immediately. When it is turned on again, it will start with the system. When the USB wireless receiver 12 is unplugged from the USB interface of the computer, it can be inserted into the USB interface 11 at the end of the pen. At this time, the circuit is connected, the sensing module is inserted, and the circuit is connected. A shutdown command is issued, so that the stylus enters a low-power standby state, which helps save power and improve battery life. This design is based on the insertion sensing module on the integrated circuit board inside the pen, which determines the insertion status of the USB wireless receiver by sensing whether it can receive electricity.
[0038] The next time you use it, you only need to unplug the wireless receiver 12 from the USB port at the end of the pen, and the system in the pen will automatically start up. In addition, the user can force the pen to start or shut down at any time through the power switch 34. This design not only solves the problem of people worrying about losing the USB wireless receiver, but also saves the trouble of finding the power switch, providing users with a more convenient use experience and increasing battery life.
