Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and in particular to a pen-shaped mouse. Background Technology

[0002] In the field of computer input devices, the mouse, as a widely used pointing device, has long focused its technological development on improving positioning accuracy and ease of use. Currently, mainstream mouse devices primarily rely on optical sensing technology. An optical sensor module on the bottom of the mouse captures high-speed images of the operating surface and calculates displacement based on image differences to control the cursor. These mice typically rely on relative friction with the desktop for positioning, requiring a certain degree of flatness and texture on the operating surface. Furthermore, when using such mice for high-precision operations such as drawing and design, users need to move their arms and wrists a considerable range to control the cursor, which can easily cause fatigue during prolonged use and negatively impact the user experience.

[0003] To overcome the limitations of the aforementioned operating methods, trackball mice were developed. These mice combine an optical sensing system with a manually scrollable ball, allowing users to control cursor movement by directly rotating the ball with their fingers, without requiring any movement of the mouse itself. This design significantly reduces the space required for operation and avoids fatigue caused by arm movement. However, most trackball mice on the market currently use a combination of mechanical structures and optical sensing modules to detect ball movement, such as indirectly measuring ball movement through a scroll wheel or encoder. This type of mechanical transmission structure suffers from uneven frictional resistance, easy wear, and limited accuracy, affecting the smoothness of operation and the accuracy of control. Furthermore, the presence of mechanical parts increases the failure rate of the device and reduces the overall durability of the product.

[0004] Therefore, how to provide a new mouse structure that can adapt to various operating environments and conform to ergonomics to improve comfort during long-term use has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is how to provide a novel mouse structure that can adapt to various operating environments and conform to ergonomics to improve comfort during long-term use.

[0006] To address the aforementioned problems, this utility model provides a pen-shaped mouse, comprising: A pen-shaped housing includes a main body and a pen tip located at one end of the main body; A slider, a portion of which is housed inside the pen tip and the remainder exposed outside the pen tip, is operable to perform omnidirectional rolling; An optical sensing module is fixedly installed inside the pen-shaped housing, with its sensing lens facing the surface of the portion of the sliding body housed inside the pen tip. The main control chip is located inside the pen-shaped housing and is connected to the optical sensing module.

[0007] A further technical solution is that the pen-shaped mouse also includes an optical lens, which is disposed inside the pen-shaped housing and located between the optical sensing module and the slider.

[0008] A further technical solution is that the outer surface of the pen-shaped shell is provided with a concave-convex structure for guiding the user's grip direction.

[0009] A further technical solution is that the pen-shaped mouse also includes a gyroscope, which is connected to the main control chip and is located inside the pen-shaped housing.

[0010] A further technical solution is that the main control chip is electrically connected to a gyroscope located inside the pen-shaped housing. The main control chip is used to collect attitude data generated by the gyroscope and calculate the attitude data through a preset algorithm inside the main control chip, thereby generating a control signal to control the movement of the cursor.

[0011] A further technical solution is that the pen-shaped mouse also includes a pressure sensor, which is disposed in the pen-shaped housing and connected to the main control chip.

[0012] A further technical solution is that the pen-shaped mouse also includes a wireless communication module, which is connected to the main control chip.

[0013] A further technical solution is that the main control chip is connected to the computer via wireless transmission or a wired interface.

[0014] A further technical solution is that the pen-shaped mouse also includes at least one function button, which is disposed on the outer surface of the pen-shaped shell and is connected to the main control chip.

[0015] A further technical solution is that the shape of the slider is spherical, and the slider and the pen tip are detachably connected.

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments.

[0023] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0024] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] See Figures 1-5 This utility model embodiment proposes a pen-shaped mouse, which includes a pen-shaped shell 10, a slider 20, an optical sensing module 30, and a main control chip 40. The specific structure is described below: The pen-shaped housing 10 includes a main body 11 and a pen tip 12 disposed at one end of the main body 11. The pen-shaped housing 10 adopts an ergonomic pen-shaped design, which allows users to operate the device in a natural pen-holding manner, greatly reducing the fatigue of the wrist and arm caused by traditional mice. It is particularly suitable for scenarios that require long-term fine-tuning operations, such as graphic design, digital art creation, or engineering drawing, thereby significantly improving user experience and operational comfort.

[0026] A portion of the slider 20 is housed inside the pen tip 12, while the remainder is exposed outside the pen tip 12. The slider 20 can be operated to roll in all directions. The slider 20 can be spherical to facilitate rolling. The user can operate the pen-shaped housing 10 to make the slider 20 roll freely on the operating surface (similar to the posture of writing), or directly roll the slider 20 with their finger; this invention is not specifically limited in this respect.

[0027] The optical sensing module 30 is fixedly disposed within the pen-shaped housing 10, with its sensing lens facing the surface of the portion of the slider 20 housed within the pen tip 12. The optical sensing module 30 acquires image data of the slider 20's surface and calculates the slider 20's movement direction and displacement based on image analysis algorithms, thereby generating corresponding cursor control signals. Because the optical sensing module 30 targets the surface features of the slider 20 itself, rather than an external operating plane, this pen mouse exhibits strong adaptability to the external environment. It can be used stably on various surfaces where traditional optical mice cannot function properly (such as glass, cloth, uneven surfaces, or air), completely eliminating dependence on an operating plane, expanding its application scenarios and practicality, and providing high precision.

[0028] The main control chip 40 is housed within the pen-shaped housing 10 and connected to the optical sensing module 30. It performs calculations based on data from the optical sensing module 30 and controls the pen mouse's operation. The main control chip 40 processes the image data transmitted from the optical sensing module 30, performs displacement calculations and signal conversions, and outputs standard cursor control signals. The high integration and efficient processing capabilities of the main control chip 40 ensure the real-time performance and stability of the entire system, making cursor control smoother and more precise, and further enhancing the reliability of the device.

[0029] This utility model provides a pen-shaped mouse, which includes a pen-shaped housing 10, a slider 20, an optical sensing module 30, and a main control chip 40. The pen-shaped housing 10 includes a main body 11 and a pen tip 12 disposed at one end of the main body 11. A portion of the slider 20 is housed inside the pen tip 12, and the remainder is exposed outside the pen tip 12. The slider 20 can be operated to perform omnidirectional scrolling. The optical sensing module 30 is fixedly disposed within the pen-shaped housing 10, with its sensing lens facing the surface of the slider 20 housed within the pen tip 12. The optical sensing module 30 is fixedly disposed within the pen-shaped housing 10, with its optical sensing window facing the surface of the slider 20, a portion of the surface of the slider 20 being housed within the pen tip 12. The main control chip 40 is disposed within the pen-shaped housing 10 and connected to the optical sensing module 30. The pen-shaped mouse proposed in this invention features an ergonomically designed pen-shaped shell 10, significantly improving grip comfort and reducing operator fatigue. The optical sensing module 30 directly detects the surface movement of the slider 20, completely eliminating reliance on a flat operating surface. It can work stably on various surfaces such as glass, fabric, and air, and maintains high precision. The main control chip 40 efficiently processes displacement signals, ensuring smooth and reliable cursor control. This design balances excellent environmental adaptability with comfort during extended use.

[0030] In some preferred embodiments, the pen mouse further includes an optical lens 50, which is disposed within the pen housing 10 and located between the optical sensing module 30 and the slider 20.

[0031] In practice, the optical lens 50 serves to converge and guide light, enabling the microscopic texture features of the slider 20 surface to be imaged more clearly and brightly onto the photosensitive element of the optical sensing module 30. Without the lens, the light source may scatter, resulting in blurry or distorted images. The introduction of the optical lens 50 corrects aberrations, providing a flatter, more focused field of view, allowing the optical sensing module 30 to capture higher contrast and clearer image sequences, thereby improving accuracy.

[0032] In some preferred embodiments, the pen tip 12 is provided with an inclined surface 121, the inclined surface 121 is provided with a receiving groove 122, and the slider 20 is embedded in the receiving groove 122.

[0033] In specific implementation, the inclined surface 121 is used to limit the user's direction of use, avoiding operational malfunctions caused by incorrect grip direction. Simultaneously, the design of the inclined surface 121 facilitates the rolling of the slider 20, and the receiving groove 122 provides a stable support structure for the slider 20, limiting its excessive wobbling, ensuring that the relative position of the exposed part and the receiving part of the slider 20 remains relatively constant when it is moved. This stability is crucial because it ensures that the optical sensing module 30 can continuously and stably align with the effective imaging area of ​​the slider 20, avoiding problems such as image blurring, data loss, or cursor jumping caused by violent shaking or displacement of the slider 20, thereby significantly improving the accuracy and reliability of cursor control. Furthermore, the inclined surface 121 is arc-shaped to improve the smoothness of operation. Understandably, the receiving groove 122 is provided with a window for the optical sensing module 30 to acquire signals, allowing the optical sensing module 30 to acquire surface images of the slider 20 through the window.

[0034] In some preferred embodiments, to further optimize the user experience and guide the correct grip direction, the outer surface of the pen-shaped housing 10 is provided with multiple concave and convex structures. These concave and convex structures (e.g., anti-slip grooves, finger rest protrusions, etc.) are ergonomically designed, and their shape and distribution naturally guide the user to hold the pen-shaped mouse at a preset optimal angle and direction, thereby avoiding operational malfunctions caused by incorrect grip direction and achieving the same technical effect as the aforementioned inclined surface solution.

[0035] In some preferred embodiments, the pen mouse further includes a gyroscope 60, which is connected to the main control chip 40 and is disposed inside the pen housing 10.

[0036] In a specific implementation, the main control chip 40 is electrically connected to a gyroscope 60 located inside the pen-shaped housing 10. The main control chip 40 is used to collect attitude data generated by the gyroscope 60 and calculate the attitude data using a preset algorithm inside the main control chip 10, thereby generating a control signal to control the movement of the cursor.

[0037] The gyroscope 60 can detect the angular velocity and attitude changes of the pen mouse in three-dimensional space in real time. When the user holds the pen mouse at different angles, or even rotates it freely in the air, the "front" orientation of the pen mouse may change. Without the gyroscope 60, the scrolling direction of the slider 20 detected by the optical sensing module 30 (based on the mouse body coordinate system) would deviate from the user's expected cursor movement direction (based on the screen coordinate system), leading to operational confusion. The attitude data provided by the gyroscope 60 allows the main control chip 40 to sense this change in the mouse body orientation and dynamically adjust the coordinate transformation algorithm from the displacement of the slider 20 to the cursor movement, automatically compensating for the effects of the pen mouse rotation. This means that no matter how the user rotates the pen mouse, sliding the slider 20 forward always corresponds to the cursor moving upward, and sliding it to the right always corresponds to the cursor moving to the right, perfectly matching the user's intuitive expectations and greatly enhancing the user experience. This makes the pen mouse a truly free-pointing device unrestricted by spatial attitude.

[0038] In some preferred embodiments, the gyroscope 60 is integrated into the main control chip 40, thereby achieving a higher degree of integration.

[0039] In some preferred embodiments, the pen mouse further includes a pressure sensor 70, which is disposed in the pen housing 10 and connected to the main control chip 40.

[0040] In practice, the pressure sensor 70 can be located inside the pen tip 12 or on the support structure of the slider 20. The pressure sensor 70 can detect the pressure applied by the user to the pen tip 12 or the slider 20 and convert this analog signal into a digital signal, which is then transmitted to the main control chip 40. The main control chip 40 can output this pressure data as a control signal independent of cursor movement to the computer. This transforms the pen mouse from a simple pointing device into a feature-rich creative tool. For example, in digital painting software, pressure data can be mapped in real time to parameters such as brush thickness and color intensity; in 3D modeling software, it can be mapped to the intensity of a sculpting brush or the rotation rate of the model. This function, which simulates the pressure sensitivity of a real paintbrush, greatly enhances the expressiveness and precision of creation, providing artists, designers, and other professional users with an unparalleled control experience and improving creative efficiency and quality.

[0041] In some preferred embodiments, the pen mouse further includes a wireless communication module 80, which is connected to the main control chip 40. Alternatively, the main control chip 40 connects to the computer via wireless transmission or a wired interface. The wireless communication module 80 may be, for example, a Bluetooth module. In this invention, the pen mouse can transmit signals to the computer via wired or wireless means, and this invention is not specifically limited in this respect.

[0042] In some preferred embodiments, the pen mouse further includes at least one function button 90, which is disposed on the outer surface of the pen housing 10 and is connected to the main control chip 40.

[0043] In practice, function keys 90 (such as left, right, middle, and custom shortcut keys) provide users with additional command input channels besides cursor movement and pressure input. Users can perform operations such as selecting, confirming, canceling, opening context menus, launching specific applications, and executing macro commands by clicking different keys. This partially frees users from complete reliance on virtual menus or keyboard shortcuts on the computer screen, allowing frequently used operations to be completed quickly while holding the mouse with one hand. This reduces the number of times the hand switches back and forth between the mouse and keyboard, significantly improving workflow efficiency, especially when browsing web pages, processing documents, or editing images.

[0044] In some preferred embodiments, the slider 20 is detachably connected to the pen tip 12. This detachable design allows the user to easily clean or replace the slider 20 when it is worn, dirty, or when a slider with different functions (such as different coefficients of friction) needs to be replaced.

[0045] In a preferred embodiment, the slider 20 has a connecting portion at its root (or top), and the pen tip 12 has a corresponding receiving groove 122. The connecting portion and the receiving groove 122 are fixed together by magnetic attraction. For example, a first magnet can be embedded in the connecting portion, and a second magnet can be embedded in the bottom of the receiving groove 122, using the attraction force between opposite magnetic poles to achieve reliable fixing and convenient disassembly of the slider 20.

[0046] In another embodiment, the connecting part and the receiving groove 122 can be connected by a snap-fit ​​mechanism. For example, a protruding buckle can be provided on the outer wall of the connecting part, and a corresponding groove can be provided on the inner wall of the receiving groove 122. The sliding body 20 is fixed by the cooperation of the buckle and the groove. During disassembly, the user can pull out the sliding body 20 with a little force.

[0047] Those skilled in the art will understand that the above-described magnetic attraction and engagement are merely examples, and any mechanical or magnetic connection method that enables detachable connection falls within the protection scope of this invention.
