[0033] In related technologies, the stylus 10 is also known as an electronic pen. The stylus 10 refers to a tool used for writing, drawing, or operating on an electronic screen. For example, the stylus 10 can be used on a tablet computer screen, thereby enabling interaction between the stylus 10 and the tablet computer. After use, the stylus 10 can be stored on the tablet computer, for example, by magnetically attaching it or by inserting it into the tablet computer's storage slot. For example, the diameter of the stylus 10 can be 9mm, which facilitates user grip and writing. With the trend towards thinner and lighter tablet computers, the thickness of tablet computers is becoming increasingly smaller. When the thickness of a tablet computer is 5mm to 8mm, the diameter of the stylus 10 is larger than the thickness of the tablet computer, making it impossible to store the stylus 10 inside the tablet computer. Therefore, this application proposes a stylus 10.

[0034] Please refer to Figures 1 to 4In some embodiments, the stylus 10 includes a housing, a pen tip 900, and a pen cap 1000. The pen tip 900 and the pen cap 1000 are respectively connected to both ends of the housing. The pen tip 900 can be used to write and draw on the screen of an electronic device. The pen cap 1000 can be used to interact with the electronic device; for example, after the pen tip 900 writes on the screen, the pen cap 1000 can be used to clear the written text. The housing includes a first housing 100 and a second housing 200. The first housing 100 and the second housing 200 are arranged around the central axis of the stylus 10. The housing can be cylindrical in shape, and the first housing 100 can be an arc-shaped sheet structure, and the second housing 200 can also be an arc-shaped sheet structure. The first housing 100 and the second housing 200 together form a storage cavity 300. The storage cavity 300 is used to house the electronic components of the stylus 10. The housing has a first state and a second state. When the housing is in the first state, the radial dimension of the housing is L1. For example, if L1 is 9mm, the radial dimension of the casing is convenient for the user to hold. Here, the radial dimension refers to the diameter of the casing, which is approximately cylindrical in shape. Furthermore, when the stylus 10 is placed inside or attached to the electronic device, the radial dimension of the casing can be the dimension along the thickness of the electronic device. For example, in the first state, the height of the casing along the thickness of the tablet is 9mm. In the second state, the radial dimension of the casing is L2. For example, if L2 is 7mm, the radial dimension of the casing is convenient for storage. Here, the radial dimension refers to the diameter of the casing, which is approximately cylindrical in shape. Furthermore, when the stylus 10 is placed inside or attached to the electronic device, the radial dimension of the casing can be the dimension along the thickness of the electronic device. For example, in the second state, the height of the casing along the thickness of the tablet is 7mm. L1 > L2; see reference for details. Figure 1 and Figure 2 , Figure 1 This indicates that the casing is in its first state. Figure 2The diagram illustrates the housing in its second state. A comparison shows that the radial dimension L1 of the housing is greater than its radial dimension L2. The first housing 100 is movable relative to the second housing 200, allowing the housing to switch between the first and second states. Specifically, the housing has a first state and a second state. The radial dimension of the housing in the first state is greater than that in the second state; that is, the radial dimension of the housing can change. The first housing 100 is movable relative to the second housing 200, allowing the housing to switch between the first and second states. Specifically, the first housing 100 can move relative to the second housing 200 to be in the first state, in which case the radial dimension of the housing is larger, making it easier for the user to hold. The first housing 100 can also move relative to the second housing 200 to be in the second state, in which case the radial dimension of the housing is smaller, making it easier to store the stylus 10 in the electronic device. In short, the stylus 10 is not only easy for the user to hold but also easy to store in the electronic device.

[0035] It should be noted that the shell is not strictly cylindrical. The radial dimension is used to facilitate understanding the dimensional changes of the shell between the first and second states. The radial dimension does not limit the shell to a cylindrical shape. In some cases, the cross-section of the shell can be not only circular, but also hexagonal or elliptical, etc.

[0036] The aforementioned scenario where the stylus 10 can be stored inside an electronic device includes the scenario where the stylus 10 is magnetically attached to the side of the electronic device. In this case, if the diameter of the stylus 10 is greater than the thickness of the electronic device, the stylus 10 will protrude relative to the electronic device after being attached, which may cause the stylus 10 to easily detach from the electronic device. Therefore, the stylus 10 of this application can switch from a first state to a second state to facilitate its attachment to the electronic device.

[0037] Furthermore, the movement of the first housing 100 relative to the second housing 200 specifically refers to two scenarios: First, the first housing 100 moves while the second housing 200 remains stationary. The first housing 100 moves closer to or away from the second housing 200. When the first housing 100 moves closer to the second housing 200, it can come into contact with the second housing 200, or the gap between the first housing 100 and the second housing 200 is small. When the first housing 100 moves away from the second housing 200, there is a larger gap between the first housing 100 and the second housing 200. Second, both the first housing 100 and the second housing 200 move, moving closer to or away from each other. When the first housing 100 moves closer to the second housing 200, it can come into contact with the second housing 200, or the gap between the first housing 100 and the second housing 200 is small. When the first housing 100 moves away from the second housing 200, there is a larger gap between the first housing 100 and the second housing 200. In the third scenario, the first housing 100 remains stationary while the second housing 200 moves. The second housing 200 moves closer to or further away from the first housing 100. When the first housing 100 moves closer to the second housing 200, it can come into contact with the second housing 200, or the gap between the first housing 100 and the second housing 200 is small. When the first housing 100 moves further away from the second housing 200, there is a larger gap between the first housing 100 and the second housing 200. The specific manner of the movement of the first housing 100 relative to the second housing 200 will be described below.

[0038] Further, please refer to Figures 2 to 6 In some embodiments, the stylus 10 further includes a driving component. The driving component is used to drive the first housing 100 closer to or further away from the second housing 200. The driving component includes a first moving member 400 and a first rotating member 500. The first moving member 400 is connected to the first housing 100 and may be fixedly connected to it. The first moving member 400 has multiple first teeth 410 along its length, i.e., it has a rack. The first rotating member 500 has second teeth 510 and may be a gear. The first teeth 410 and second teeth 510 mesh, and rotating the first rotating member 500 causes the first moving member 400 to move closer to or further away from the second housing 200. Specifically, after the first rotating member 500 rotates, the second teeth 510 drive the first teeth 410 to move, causing the first moving member 400 to move, thus moving the first housing 100 closer to or further away from the second housing 200. The above setup features a simple structure and convenient operation, making it easy for users to switch the casing between the first and second states.

[0039] Further, please refer to Figures 2 to 6In some embodiments, the drive assembly further includes a second moving member 600. The second moving member 600 is connected to the second housing 200, and may be fixedly connected to the second housing 200. The second moving member 600 has multiple third teeth 610 along its length, that is, a rack is provided on the second moving member 600. The third teeth 610 mesh with the second teeth 510, meaning that the first moving member 400 and the second moving member 600 are respectively located on both sides of the first rotating member 500. Rotating the first rotating member 500 will cause the first moving member 400 and the second moving member 600 to move synchronously. Specifically, synchronous movement of the first moving member 400 and the second moving member 600 means that they move closer to each other or move further away from each other synchronously. This allows the first housing 100 and the second housing 200 to move closer to or further away from each other. Specifically, the movement of the first rotating member 500 can bring the first housing 100 and the second housing 200 closer together or further apart, which allows the user to easily switch the housings between the first and second states. Furthermore, the fact that the first housing 100 and the second housing 200 can be moved closer or further apart by a single first rotating member 500 facilitates user operation and also saves costs.

[0040] Furthermore, in some embodiments, the drive assembly further includes a second moving member 600 and a second rotating member. The second moving member 600 is connected to the second housing 200, and may be fixedly connected to the second housing 200. The second moving member 600 has a plurality of third teeth 610 along its length, that is, a rack is provided on the second moving member 600. The second rotating member has a fourth tooth, and the third teeth 610 and the fourth tooth mesh. Rotating the second rotating member causes the second moving member 600 to move the second housing 200 closer to or away from the first housing 100. Specifically, rotating the first rotating member 500 and the second rotating member simultaneously can make the first housing 100 and the second housing 200 move closer to or away from each other, which allows the user to easily switch the housing between a first state and a second state.

[0041] Further, please refer to Figure 3 and Figure 8In some embodiments, the driving assembly further includes a driving element 1300. The driving element 1300 is connected to the first rotating element 500 and is used to drive the first rotating element 500 to move. Specifically, the driving element 1300 can be a motor, which can be connected to the first rotating element 500 via a transmission shaft, so that when the motor rotates, it can drive the first rotating element 500 to rotate. The driving element 1300 enables the automatic folding effect of the stylus 10's housing. That is, when the user is not using the stylus 10, the driving element 1300, upon receiving a program command, can drive the first rotating element 500 to rotate, thereby switching the housing from a first state to a second state, which saves the user time and effort. Furthermore, the high precision of the motor allows the first housing 100 to accurately approach the second housing 200, effectively preventing mutual damage between the first housing 100 and the second housing 200. Furthermore, in some other embodiments, the first rotating member 500 can also be rotated manually. Rotating the first rotating member 500 allows the first housing 100 and the second housing 200 to move closer or further apart, facilitating the user's switching between the first and second states of the housing. For example, please refer to... Figure 4 and Figure 8 , Figure 4 and Figure 8 The drive component 1300 can be replaced by a rotating shaft. After the user turns the rotating shaft, the rotating shaft can drive the first rotating component 500 to rotate, thereby switching the housing from the first state to the second state. In some embodiments, the rotating shaft can be part of the pen cap 1000. That is, after the user turns the pen cap 1000, the first rotating component 500 can be rotated, thereby switching the housing from the first state to the second state.

[0042] Furthermore, in the first state, the user holds the stylus 10 for use. The first state provides a good grip experience. To prevent the shell from switching from the first state to the second state with slight force, a rotational damper can be incorporated. Specifically, in some embodiments, the drive assembly further includes a damper connected to the first rotating member 500. The damper increases the resistance to rotation of the first rotating member 500. Specifically, the damper can be a rotational damper. The working principle of the rotational damper is mainly based on its internal damping medium and damping structure. When the rotational damper rotates under external force, the damping medium generates flow resistance in the damping structure, thereby slowing down the rotation speed. After the rotational damper is connected to the first rotating member 500, it applies resistance to the first rotating member 500, preventing it from rotating easily. Thus, when the user uses the stylus 10, the shell will not easily switch from the first state to the second state, thus affecting user experience. In addition, the damper can also control the stroke of the first housing 100 relative to the second housing 200.

[0043] Further, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 In some embodiments, the stylus 10 further includes a limiting member 700 disposed in the storage cavity 300. The limiting member 700 has a limiting groove 710, and the first moving member 400 is disposed in the limiting groove 710. The limiting groove 710 can restrict the position and direction of the first moving member 400 during movement, ensuring that the first moving member 400 moves along a predetermined trajectory, thereby allowing the first housing 100 to move closer to or further away from the second housing 200, avoiding unnecessary collisions or deviations. The shape of the first moving member 400 can be square, and the shape of the limiting groove 710 can be adapted to the shape of the first moving member 400. Specifically, the limiting member 700 effectively ensures that the first moving member 400 reliably and stably drives the first housing 100 to move.

[0044] Since there is relative movement between the first housing 100 and the second housing 200, directly placing electronic components into the storage cavity 300 may cause damage to the electronic components from either the first housing 100 or the second housing 200. Therefore, the pen body 800 can be used to protect the electronic components. For details, please refer to... Figure 2 , Figure 3 , Figure 4 and Figure 7In some embodiments, the stylus 10 further includes a pen body 800, which is disposed in the storage cavity 300. The pen body 800 has a receiving cavity 810 for accommodating electronic components. The pen body 800 may be cylindrical. The aforementioned limiting member 700 ensures the stability of the movement of the first moving member 400. The limiting member 700 and the pen body 800 are an integral structure. That is, the pen body 800 and the limiting member 700 are formed by an integral molding process, and the pen body 800 may be made of plastic. Specifically, the pen body 800 is provided with a limiting groove 710 to ensure the stability of the movement of the first moving member 400. This can make full use of the structure of the pen body 800 itself, thereby making reasonable use of the space of the storage cavity 300 and saving the cost of the stylus 10.

[0045] Further, please refer to Figure 1 and Figure 3 In some embodiments, the stylus 10 further includes a closure 1100 having a cavity 1200 in which the housing is disposed. Specifically, the closure 1100 can further protect the housing and the components inside the housing. At the same time, after the closure 1100 encloses the housing, it can also enhance the integrity of the housing of the stylus 10.

[0046] Furthermore, in some embodiments, the closure 1100 is made of an elastic material. An elastic material is a type of material that can deform under external force and quickly return to its original shape and size after the force is removed. Elastic materials can be rubber, silicone, or acrylic elastomers, etc. Specifically, the closure 1100 has a cavity 1200, and the shell is located within the cavity 1200, where the closure 1100 wraps around the outer periphery of the shell. When the closure 1100 wraps around the shell, it can be in a contracted state. In addition to being an elastic material, the closure 1100 can also be made of soft materials, such as elastic fabric, which can improve the user's grip on the stylus 10.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
