Description

Technical Field

[0001] This utility model relates to the field of pressure-sensitive pen technology, specifically a pressure-sensitive pen for animation design. Background Technology

[0002] In the field of digital art creation, especially in the animation design industry, pressure-sensitive pens, as core input devices, have gradually replaced traditional hand-drawing tools and become a key medium for designers to realize their creative expression, thanks to their ability to accurately capture pen pressure, tilt angle, and writing speed.

[0003] However, in actual use of pressure-sensitive pens, when animation designers place the pens during breaks in their creative process, they mainly use random placement or ordinary pen holders. Accidental collisions can cause the pens to roll and fall, resulting in pen tip deformation. Secondly, when users need to draw long, thick lines or dark-colored patterns, they need to maintain a certain amount of force when holding the pen for a long time, which can easily cause hand fatigue. Utility Model Content

[0004] This utility model provides a pressure-sensitive pen for animation design. Through the cooperation of a protective tube, a connecting groove, and a buffer sleeve, the pen tip and button can be synchronously stored and protected, and the hand fatigue caused by long-term creation can be alleviated. This solves the problem mentioned in the background art that the pen tip is easy to deform and easily causes hand fatigue.

[0005] This utility model provides the following technical solution:

[0006] A pressure-sensitive pen for animation design includes a pen barrel with a pen tip at the bottom and a pressure detection component adapted to the pen tip inside the barrel. It also includes a protective sleeve forming a protective space, wherein a connector is provided within the protective space, and the pen barrel has a connecting groove in which the connector is disposed. When the connector moves along the connecting groove, the pen tip disengages from or enters the protective space. A buffer sleeve is disposed on the protective sleeve, and the buffer sleeve has a hand-holding area.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Reference Figures 1-5 This utility model provides a pressure-sensitive pen for animation design. Its basic components mainly include a pen barrel 100, which has a streamlined columnar structure that is suitable for hand use. A pen tip 200 is fixedly installed at the bottom of the pen barrel 100. The pen tip 200 is made of wear-resistant conductive material and can interact with the touch screen of a tablet or mobile phone by forming electromagnetic or capacitive signals. The pen barrel 100 is embedded with a pressure detection component that is compatible with the pen tip 200. This component includes a pressure sensor and a signal processing module, which can convert the drawing pressure on the pen tip 200 into a corresponding electrical signal, and then map it into a gradient effect of line thickness and color intensity, so as to meet the fine drawing needs of character hair and scene shadow gradient in animation design.

[0029] The specific principle is as follows: The tablet or mobile phone touch screen is a capacitive screen with uniformly distributed transparent electrodes on the surface, forming a capacitor matrix. The pen tip 200 is made of a wear-resistant conductive material (such as conductive rubber or a metal probe). The pen barrel 100 contains a pressure-sensitive sensor, a capacitive sensor, or a signal processing module and a battery. The battery is electrically connected to the charging connector 102. When the pen tip 200 touches the screen, it forms a "capacitive coupling" with the screen electrodes (similar to finger touch, but the pen tip 200 has a smaller conductive area and higher precision). When the pen tip 200 is pressed, the resistance / capacitance value of the pressure sensor changes after being pressed, causing a change in the coupling capacitance between the pen tip 200 and the screen. Subsequently, the signal processing module analyzes the pressure magnitude, and the built-in pressure-sensitive sensor converts it into physical quantities such as resistance, capacitance, or magnetic field changes. After being encoded and amplified by the signal processing module, it is transmitted wirelessly (electromagnetically, capacitively) or wired to the graphics tablet, graphics display, and other supporting devices. After being analyzed by the devices, it is mapped to changes in line thickness, transparency, and other pen strokes, ultimately achieving a natural hand-drawing experience. This is existing technology.

[0030] Specifically, a protective sleeve 400 is fitted onto the outer side of the pen barrel 100. The protective sleeve 400 is a hollow cylindrical structure, that is, a protective space with openings at both ends, specifically designed to accommodate the pen tip 200. A limiting block 401 (i.e., a connector) is fixedly installed on the inner wall of the protective sleeve 400. Correspondingly, a spirally extending connecting groove 300 is formed on the outer wall of the pen barrel 100. The limiting block 401 is slidably connected within the connecting groove 300. At the same time, the inner diameter of the protective sleeve 400 is consistent with the diameter of the pen barrel 100, ensuring that the protective sleeve 400 can slide stably along the pen barrel 100, avoiding jamming or displacement during state switching. In addition, a mounting hole 402 is formed on the side wall of the protective sleeve 400, the size of which is adapted to the button 101 on the pen barrel 100, for the storage and exposure of the button 101.

[0031] Specifically, the outer side of the protective sleeve 400 is fitted with a buffer sleeve 500. The buffer sleeve 500 is made of soft, non-slip silicone material, which has good elasticity and grip comfort, and can effectively relieve hand pressure from holding the pen for a long time. The buffer sleeve 500 is a one-piece molded structure, including a main connecting sleeve 501, a convex sleeve 502 and a concave sleeve 503. The main connecting sleeve 501 fits tightly against the upper outer wall of the protective sleeve 400. The convex sleeve 502 is located on the lower outer wall of the buffer sleeve 500. Its outward arc structure can adapt to the support of the palm base, avoiding direct contact between the palm and the table during creation and causing friction. The concave sleeve 503 is connected between the main connecting sleeve 501 and the convex sleeve 502. Its inward concave curved surface forms a hand-holding area that fits the fingers. The curvature of this area is adapted to the common "three-finger pen grip" posture in animation design, which can distribute the pressure of the fingers pressing. Meanwhile, the buffer sleeve 500 has a through hole 600 at the position of the mounting hole 402 on the protective cylinder 400. The through hole 600 and the mounting hole 402 are matched in size and position to form a space for accommodating the button 101.

[0032] Specifically, a button 101 is embedded in the side wall of the pen barrel 100 at the position corresponding to the through hole 600. The button 101 is electrically connected to the pressure detection component inside the pen barrel 100. Designers can customize it with the required driver software to perform commonly used functions in animation design such as "eraser switching", "layer switching", and "undo operation". The charging connector 102 on the pen barrel 100 uses a Type-C interface or a Lightning interface to be compatible with mainstream charging devices and ensure battery life during long animation creation.

[0033] The working principle is as follows: When an animation designer needs to create, they can hold the concave sleeve 503 of the buffer sleeve 500 and slide the buffer sleeve 500 along the spiral connecting groove 300 on the outer wall of the pen barrel 100 to move it upward until the pen tip 200 is completely out of the protective space and exposed. At the same time, the button 101 on the pen barrel 100 is exposed from the space formed by the through hole 600 and the mounting hole 402. In this state, the soft silicone material of the buffer sleeve 500 and the concave sleeve 503 fit together to effectively distribute the pressure of holding the pen. Even if the designer draws thick lines of large animation scenes for a long time (such as the outline of the scene) or repeatedly adjusts the fine strokes of character details (such as the texture of the character's eyes), the fatigue of the fingers and palms can be reduced. The exposed button 101 allows the designer to switch tools with one click during the creation process.

[0034] When the pressure-sensitive pen needs to be placed during breaks in the creative process, the concave sleeve 503 of the buffer sleeve 500 can be held and the buffer sleeve 500 can be slid along the spiral connecting groove 300 on the outer wall of the pen barrel 100 to move it downwards until the pen tip 200 is completely inside the protective space of the protective sleeve 400. At the same time, the button 101 will also be stored in the protective space of the protective sleeve 400. At this time, the protective sleeve 400 forms a physical enclosure for the pen tip 200, avoiding the risk of collision and falling when placed carelessly (solving the problem of easy deformation of the pen tip 200 in the background technology); the button 101 is blocked to prevent accidental touch and prevent the creative file from being accidentally modified; and the convex sleeve 502 of the buffer sleeve 500 can serve as a support structure, allowing the pen barrel 100 to be placed stably on the table without relying on an additional pen holder.

[0035] In the above solution, the spiral connecting groove 300 and the protective sleeve 400 can be used to simultaneously store and protect the pen tip 200 and the button 101, preventing the pen tip 200 from easily deforming. In addition, the fit of the buffer sleeve 500 to the hand area can alleviate hand fatigue during long periods of creation.
