Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a stylus and an electronic device. Background Technology

[0002] A stylus is a pen-shaped device used for input, writing, drawing, or manipulation on a touchscreen or dedicated graphics tablet. In some existing technologies, to provide a better writing and grip experience, the stylus's diameter is 8mm or larger. In other existing technologies, considering ease of storage and portability, the stylus's diameter is less than 5mm. However, styluses with larger diameters are inconvenient to store and carry. Conversely, styluses with too small a diameter offer a poor writing and grip experience. Therefore, currently, styluses cannot simultaneously achieve a good writing experience and portability. Utility Model Content

[0003] This application provides a stylus and an electronic device that allows the stylus to have both a good grip and a convenient storage design.

[0004] In a first aspect, this application provides a stylus. The stylus includes a pen body and a first component, both extending along a first direction, and the pen body having a cavity to accommodate the first component. The first component is a freely detachable part of the stylus, and the stylus has a first state and a second state depending on the position of the first component relative to the pen body. In the first state, the first component is accommodated within the cavity of the pen body. In the second state, the first component is fixed to the outer surface of the pen body, and the first component and the pen body are joined to form a columnar grip structure. This grip structure can be cylindrical or prismatic. Since the grip structure is composed of the first component and the pen body, the diameter of the grip structure is thicker, thus facilitating gripping.

[0005] The stylus described above can switch between a first state and a second state, making its diameter adjustable. When the stylus needs to be stored, it can be in the first state. When it needs to be used for writing, drawing, or other functions, it can be in the second state, which thickens the grip area, making it easier to hold and reducing discomfort from prolonged use.

[0006] In some alternative technical solutions, the stylus also includes a pen cap, which is detachably connected to the pen body. Optionally, the pen cap and pen body can be threaded together. Alternatively, the pen cap and pen body can also be plugged in. Furthermore, when the stylus is in its first state, the first component and pen cap are detachably connected. On one hand, the first component can be attached to the pen cap, thus assembling it into a single unit. In this way, as the pen cap moves away from the pen body in a first direction, the first component can move along with the pen cap, gradually detaching from the pen body. On the other hand, after the first component detaches from the pen body, it can separate from the pen cap, thus becoming an independent entity fixed to the outer surface of the pen body, allowing the stylus to switch from the first state to the second state.

[0007] In one specific implementation of the above technical solution, the first component has a limiting surface, which is perpendicular or substantially perpendicular to the first direction. The pen cap includes a pen cap body and a connector. The connector has a first end and a second end arranged along the first direction. The first end is fixedly connected to the pen cap body, and the second end has a limiting portion. In the first state, the limiting surface and the limiting portion are arranged along the first direction, and the limiting surface is located on the side of the limiting portion facing the first end. In addition, from a projection perspective, the orthographic projection of the limiting portion along the first direction is at least partially located within the orthographic projection of the limiting surface along the first direction. It can also be understood that the limiting surface is located on the movement path of the limiting portion along the first direction. During movement, the limiting portion can abut against the limiting surface, thereby applying a pushing force to the limiting surface, causing the first component to move in the same direction, and ultimately causing the first component to move out of the pen body.

[0008] In some alternative technical solutions, the stylus also includes a cap and an elastic element. The cap and the pen body are detachably connected. The elastic element has the ability to stretch and deform along a first direction. That is, the elastic element can extend or shorten along the first direction. Optionally, the elastic element can be a spring. In the first state, the elastic element is located between the cap and the first component, and the elastic element undergoes compressive deformation. The end of the elastic element away from the cap abuts against the first component, thereby pressing against the first component, reducing the wobbling of the first component, and improving the stability of the first component.

[0009] In the second state, the first component and the pen body can be fixed in various ways. In some alternative technical solutions, the first component includes a first magnet, and the pen body includes a second magnet. In the second state, the first magnet and the second magnet attract and fix each other, thereby securing the first component and the pen body. In the specific arrangement of the first and second magnets, the first component may include a protective shell, with the first magnet located inside the protective shell. The pen body may include a pen holder, with the second magnet located inside the pen holder. The aforementioned arrangement of the first and second magnets does not damage the surface structure of the first component and the pen body, thereby improving the appearance of the stylus.

[0010] In other alternative technical solutions, one of the first component and the pen body can be provided with a buckle, and the other can be provided with a slot. The first component and the pen body can be fixed by the cooperation of the buckle and the slot.

[0011] To enhance the fixing effect between the first component and the pen body, some alternative technical solutions include a third magnet in the first component, with the third magnet and the first magnet arranged at intervals along a first direction. The pen body also includes a fourth magnet, with the fourth magnet and the second magnet arranged at intervals along the first direction. In the second state, the third magnet and the fourth magnet are opposite each other and are attracted and fixed together.

[0012] In the above technical solution, the polarity of the third magnet facing the pen body and the polarity of the second magnet facing the first component can be the same, and the polarity of the fourth magnet facing the first component and the polarity of the first magnet facing the pen body can be the same. Thus, during the installation of the first component onto the outside of the pen body, when the third and second magnets are facing each other, and the fourth magnet and the first magnet are facing each other, the third and second magnets will repel each other, and the fourth magnet and the first magnet will also repel each other, preventing the first component from being fixed to the surface of the pen body. During the assembly of the first component, the attraction and repulsion effects between the magnets can determine whether the installation method of the first component is correct, thus preventing mistaken attachment.

[0013] In the specific design of the first component, it can be a battery component, which powers the electrical components within the stylus. Alternatively, this application can utilize existing components within the stylus as the first component, thereby reducing the introduction of other components and simplifying the stylus's structure. Specifically, the first component includes a battery cell. The pen body includes a main circuit board, in which the battery cell and the main circuit board are electrically connected in both a first and a second state. The main circuit board houses electronic components that can obtain power from the battery cell through the main circuit board.

[0014] In the first state, to electrically connect the battery cell and the main circuit board, in one optional implementation, the first component further includes a first electrical connection portion, which is electrically connected to the battery cell. The pen body also includes a second electrical connection portion, which is electrically connected to the circuit board. In the first state, the first and second electrical connection portions are in contact and electrically connected, thereby electrically connecting the battery cell and the main circuit board. When the stylus switches from the first state to the second state, the first and second electrical connection portions separate, and the connection is broken.

[0015] In the second state, to electrically connect the battery cell and the main circuit board, in one optional implementation, the outer surface of the pen body has a third electrical connection portion, which is electrically connected to the main circuit board. In the second state, the first and third electrical connection portions contact and are electrically connected, thereby electrically connecting the battery cell and the main circuit board.

[0016] In the specific design of the pen body, the pen body includes a first connecting surface, which is planar and parallel to a first direction. The first component includes a second connecting surface, which is also planar and parallel to the first direction. In the second state, the first and second connecting surfaces are fitted and fixed together. Thus, the first component and the pen body have a large contact area, reducing the likelihood of misalignment, and the overall structure is relatively compact.

[0017] In some alternative technical solutions, the pen body includes a writing section, a grip section, and a receiving section arranged sequentially along a first direction, the receiving section having a cavity for accommodating a first component. In a second state, at least a portion of the first component is fixed to the outer surface of the grip section. More specifically, the first component can be integrally fixed to the outer surface of the grip section, thereby assembling with the grip section to form a columnar grip structure. Alternatively, a portion of the first component is fixed to the surface of the grip section, and another portion is fixed to the surface of the receiving section.

[0018] Specifically, the cross-sectional area of ​​the receiving portion is larger than that of the grip portion. That is, along the length of the pen body, the thickness of the pen body is uneven, with the receiving portion being thicker than the grip portion. By making the receiving portion thicker, it is easier to place the first component within the cavity of the receiving portion. Optionally, the receiving portion and the grip portion are smoothly connected.

[0019] Secondly, this application provides an electronic device. The electronic device includes a device body and a stylus as described in any of the first aspects, the stylus being used for interactive connection with the device body.

[0020] The stylus described above can switch between a first state and a second state, making its diameter adjustable. When the stylus needs to be stored, it can be in the first state. When it needs to be used for writing, drawing, or other functions, it can be in the second state, which thickens the grip area, making it easier to hold and reducing discomfort from prolonged use.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this application are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this application. The accompanying drawings of the embodiments of this application are for illustrating relative positional relationships only and do not represent actual scale.

[0048] It should be noted that specific details are set forth in the following description to facilitate understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] To facilitate understanding of the stylus and electronic device provided in this application, the application scenarios of this application will be introduced first.

[0050] With the continuous evolution of cutting-edge technologies, styluses have been deeply integrated into various smart devices, becoming a standard accessory for important terminals such as mobile phones, tablets, and laptops. Styluses not only support precise and smooth writing and drawing, but also integrate intelligent interactive functions such as one-click clearing, significantly improving the efficiency and experience of digital creation.

[0051] Typically, the size of a stylus pen is fixed. When considering the grip, a stylus should have a larger diameter to facilitate a comfortable hold and improve the user experience. When considering storage, a stylus should be thinner to minimize its footprint and make it easier to store. Therefore, it's difficult for a stylus to achieve both good grip and easy storage.

[0052] In view of the above, this application provides a stylus and an electronic device that allows the stylus to have both good grip and storage performance.

[0053] Figure 1 Schematic diagrams of the structure of the electronic device provided in this application in some embodiments, such as Figure 1As shown, the electronic device includes a device body 1 and a stylus 2, which is used to interact with the device body 1. In other words, the device body 1 can sense the state of the stylus 2, such as the position of the stylus 2 and the pressure applied by the stylus 2 to the device body 1, and the behavior of the stylus 2, as an input signal, can affect the output display of the device body 1.

[0054] This application does not limit the types of the device body 1 and the stylus 2. As an example, the device body 1 can be a mobile phone, tablet computer, laptop computer, graphics tablet, or digital display. The stylus 2 includes, but is not limited to, an active capacitive stylus, a passive capacitive stylus, or an electromagnetic resonance stylus.

[0055] In some embodiments, the stylus 2 and the device body 1 are detachably connected. When the stylus 2 is needed, it can be separated from the device body 1. After use, the stylus 2 can be placed in a preset position on the device body 1, thus fixing the stylus 2 and the device body 1 together and reducing the risk of loss or damage to the stylus 2. Therefore, the device body 1 can serve as a storage container for the stylus 2.

[0056] There are several ways in which the stylus 2 and the device body 1 can be detachably connected. For example, the stylus 2 has a first magnetic component, and the device body 1 has a second magnetic component. When the stylus 2 is placed in a preset position on the device body 1, the first and second magnetic components attract each other, fixing the stylus 2 to the device body 1. Applying external force to the stylus 2 to overcome the attraction between the first and second magnetic components allows the stylus 2 to be separated from the device body 1. Another example is that one of the stylus 2 and the device body 1 has a snap-fit, and the other has a slot. The engagement of the snap-fit ​​and the slot allows the stylus 2 to be fixed to the device body 1. When external force is applied to the stylus 2, causing the snap-fit ​​to disengage from the slot, the stylus 2 can be separated from the device body 1. Of course, the stylus 2 can also be connected to the device body 1 in other detachable ways, which will not be listed in this application.

[0057] In other embodiments, a storage device may be provided for storing the stylus 2. The stylus 2 can be detachably connected to the storage device in the manner described above, which will not be elaborated upon in this application.

[0058] Figure 2 The structural diagrams of the stylus provided in this application in some embodiments are as follows: Figure 2As shown, the stylus 2 includes a pen body 10 and a first component 20. The pen body 10 and the first component 20 extend along a first direction X, and the pen body 10 has a cavity to accommodate the first component 20. The first component 20 is a detachable part of the stylus 2. Depending on the position of the first component 20 relative to the pen body 10, the stylus 2 has a first state and a second state. In the first state, the first component 20 is accommodated within the cavity of the pen body 10. In the second state, the first component 20 is detached from the cavity of the pen body 10, and the first component 20 is fixed to the outer surface of the pen body 10, forming a columnar grip structure with the pen body 10. In this state, the first component 20 and the pen body 10 are detachably connected. After the first component 20 is separated from the pen body 10, it can be placed back into the cavity of the pen body 10, thereby switching the stylus 2 from the second state back to the first state.

[0059] Figure 3 A schematic diagram of the structure of the stylus provided in this application in its first state. Figure 4 A schematic diagram of the stylus provided in this application in its second state. Figure 3 As shown, in the first state, the first component 20 is hidden inside the pen body 10, and the cross-sectional area of ​​the pen body 10 determines the thickness of the stylus 2. Figure 4 As shown, in the second state, the first component 20 is moved from inside the pen body 10 to outside the pen body 10 and assembled with the pen body 10 to form a columnar grip structure. This grip structure is composed of the first component 20 and the pen body 10, and its cross-sectional area is larger than that of the pen body 10. Comparing the stylus 2 in the first state and the stylus 2 in the second state, the stylus 2 in the first state is thinner, occupies less space, and is easier to store. In the second state, because the first component 20 is moved from inside the pen body 10 to outside the pen body 10 and assembled with the pen body 10 to form a grip structure, the grip structure is thicker, making it easier for the user to hold while writing, alleviating discomfort caused by prolonged holding, and improving the user experience.

[0060] The stylus 2 described above can switch between a first state and a second state, thus making its diameter adjustable. When the stylus 2 needs to be stored, it can be in the first state. When the stylus 2 needs to be used for writing, drawing, or other functions, it can be in the second state, which thickens the grip area, making it easier to hold and reducing discomfort from prolonged use. Of course, in some scenarios, the stylus 2 can also be used for writing and drawing when in the first state.

[0061] Figure 5 for Figure 4 The AA sectional view of the stylus at the grip structure shown is also included. Figure 2 , Figure 3 , Figure 4 and Figure 5 The pen body 10 includes a first connecting surface 101, which is planar and parallel to the first direction X. The first component 20 includes a second connecting surface 201, which is also planar and parallel to the first direction X. When the stylus 2 is in the second state, the first connecting surface 101 and the second connecting surface 201 are fitted and fixed together. Thus, the first component 20 and the pen body 10 have a large contact area, making misalignment less likely, and the overall structure is relatively compact. When the stylus 2 is in the first state, the first connecting surface 101 can fit against the device body 1, thereby achieving a tight connection with the device body 1 and improving the fixation effect of the stylus 2.

[0062] Optionally, the first connecting surface 101 can penetrate the pen body 10 along the first direction X, and the second connecting surface 201 can penetrate the first component 20 along the first direction X. That is, the first connecting surface 101 can extend from one end of the pen body 10 to the other end of the pen body 10, and the second connecting surface 201 can extend from one end of the first component 20 to the other end of the first component 20.

[0063] To clearly describe the structure of the pen body 10 and the first component 20, a second direction Y and a third direction Z are defined. The second direction Y is perpendicular to both the first connecting surface 101 and the second connecting surface 201. The third direction Z is perpendicular to the first direction X and also perpendicular to the second direction Y. In some embodiments, the width of the first connecting surface 101 along the third direction Z is substantially equal to the width of the second connecting surface 201 along the third direction Z.

[0064] Please continue to refer to this. Figure 2 , Figure 3 , Figure 4 and Figure 5 For the pen body 10, the pen body 10 also includes a first curved surface 102, which protrudes in a direction away from the first connecting surface 101. The first curved surface 102 and the first connecting surface 101 are connected and form the peripheral surface of the pen body 10. In the specific configuration of the first curved surface 102, the first curved surface 102 can be an arc surface. Alternatively, the first curved surface 102 can also include multiple sub-surfaces, each extending along a first direction X. For any given sub-surface, the sub-surface can be a plane or an arc surface, and multiple sub-surfaces are sequentially connected to form the aforementioned curved surface.

[0065] For the first component 20, the first component 20 also includes a second curved surface 202, which protrudes in a direction away from the second connecting surface 201. The second curved surface 202 connects with the second connecting surface 201 and forms the peripheral surface of the first component 20. When specifically setting the second curved surface 202, the setting method of the first curved surface 102 can be referred to, which will not be described in detail here.

[0066] like Figure 4 As shown, from an appearance standpoint, the pen body 10 and the first component 20 can be assembled into a cylindrical grip structure. This grip structure, due to its smooth curved surface, improves the feel of the grip. Figure 5 As shown, within a cross-section perpendicular to the first direction X, the first curved surface 102 and the second curved surface 202 can form a structure resembling a circle. The cross-sectional area of ​​the pen body 10 can be equal to or unequal to the cross-sectional area of ​​the first component 20. For example, in some embodiments, the cross-sectional area of ​​the pen body 10 can be equal to the cross-sectional area of ​​the first component 20, and both the cross-sections of the pen body 10 and the first component 20 can be semicircular. In other embodiments, the cross-sectional area of ​​the pen body 10 can be larger than the cross-sectional area of ​​the first component 20, the cross-section of the pen body 10 is more than a semicircle, and the cross-section of the first component 20 is less than a semicircle.

[0067] In order to remove the first component 20 from the pen body 10, as Figure 3 and Figure 4 As shown, in some embodiments, the stylus 2 includes a cap 30 located at the end of the pen body 10 and detachably connected to the pen body 10. Optionally, the cap 30 and the pen body 10 can be threaded together. Alternatively, the cap 30 and the pen body 10 can also be plugged in. When the stylus 2 is in a first state, the cap 30 seals the cavity of the pen body 10, so that the first component 20 is encapsulated inside the pen body 10. When the cap 30 is removed from the end of the pen body 10, the cavity can be opened, thereby allowing the first component 20 to be removed from the pen body 10.

[0068] In other embodiments, the pen body 10 includes a detachably connected first part and a second part, which form a cavity for accommodating the first component 20. The first and second parts can be separated to expose the first component 20, allowing it to be removed. Of course, other structural designs can also be used to remove the first component 20 from the pen body 10, which will not be listed here.

[0069] In this application, the stylus 2 includes a cap 30, and the first component 20 is removed from the pen body 10 by disassembling the cap 30. To facilitate removal of the first component 20 from the pen body 10, in some embodiments, the first component 20 and the cap 30 are detachably connected in the first state. That is, the first component 20 can be connected to the cap 30, thus assembling them as a whole. When the cap 30 moves away from the pen body 10 along the first direction X, the first component 20 can move along with the cap 30, gradually detaching from the pen body 10. After the first component 20 detaches from the pen body 10, it can separate from the cap 30, thus becoming an independent entity fixed to the outer surface of the pen body 10, allowing the stylus 2 to switch from the first state to the second state.

[0070] It is worth noting that by making the first component 20 and the pen cap 30 detachably connected, in addition to removing the first component 20 while removing the pen cap 30, the shaking of the first component 20 inside the pen body 10 can be reduced when the stylus 2 is in the first state, and the abnormal noise caused thereby can be reduced accordingly, thus improving the user experience of the stylus 2.

[0071] Of course, in the first state, the first component 20 may not be physically connected to the pen cap 30. After removing the pen cap 30, the first component 20 can be removed from the pen body 10 with the help of some tools.

[0072] Figure 6 Assembly diagrams of the pen cap and first component provided in this application in some embodiments, such as... Figure 6 As shown, the first component 20 has a limiting surface 203. Optionally, the limiting surface 203 may be perpendicular or substantially perpendicular to the extending direction (i.e., the first direction X) of the first component 20. The pen cap 30 includes a pen cap body 31 and a connector 32, wherein the pen cap body 31 and the pen body 10 are detachably connected. The connector 32 has a first end and a second end arranged along the first direction X, the first end being fixedly connected to the pen cap body 31, and the second end having a limiting portion 321. When the stylus 2 is in the first state, the limiting surface 203 and the limiting portion 321 are arranged along the first direction X, and the limiting surface 203 is located on the side of the limiting portion 321 facing the first end. From a projection perspective, the orthographic projection of the limiting portion 321 along the first direction X is at least partially located within the orthographic projection of the limiting surface 203 along the first direction X. It can also be understood that the limiting surface 203 is located on the moving path of the limiting portion 321 along the first direction X. During the movement, the limiting part 321 can abut against the limiting surface 203, thereby applying a pushing force to the limiting surface 203, causing the first component 20 to move in the same direction, and finally causing the first component 20 to move out of the pen body 10.

[0073] Figure 7This is a schematic diagram showing the state of the pen cap and the first component during the process of removing the pen cap. (Example) Figure 7 As shown, when the pen cap body 31 moves away from the pen body 10 along the first direction X, the connector 32 will move along with the pen cap body 31, and the limiting part 321 located at the second end of the connector 32 will also move accordingly. The limiting surface 203 of the first component 20 is located on the moving path of the limiting part 321. After the limiting part 321 abuts against the limiting surface 203, it will apply a pushing force to the limiting surface 203, causing the first component 20 to move in the same direction, and finally causing the first component 20 to move out of the pen body 10.

[0074] There are multiple ways to specifically set the aforementioned limiting surface 203. For example... Figure 6 and Figure 7 As shown, in some embodiments, the side surface of the first component 20 has a groove 204, and the aforementioned limiting surface 203 is located on the inner wall of the groove 204. In the first state, the limiting part 321 can be accommodated in the groove 204 and abuts against the limiting surface 203. During the process of removing the pen cap 30, the first component 20 can be pulled out from the pen body 10 by the cooperation of the limiting surface 203 and the limiting part 321.

[0075] It is worth noting that, based on the above design, except for the area corresponding to the groove 204, the main body of the first component 20 can be a columnar structure with uniform thickness. Thus, when the first component 20 is installed on the outer surface of the pen body 10, the main body of the first component 20 can fit tightly against the pen body 10, making the overall structure more compact. If a protrusion is provided on the surface of the first component 20, with the limiting surface 203 located on the side surface of the protrusion, although the cooperation between the limiting surface 203 and the limiting part 321 can achieve the effect of pulling the first component 20 out of the pen body 10 while removing the pen cap 30, the protrusion will interfere with the pen body 10 when the first component 20 is installed on the outer surface of the pen body 10. To avoid the protrusion, an avoidance groove needs to be provided on the outer surface of the pen body 10 to accommodate the protrusion, but this damages the surface structure of the pen body 10. Furthermore, when the stylus 2 is in the first state, the aforementioned clearance groove will also be exposed, thus affecting the appearance of the stylus 2 in the first state.

[0076] In other embodiments, the limiting surface 203 can be located on the end face of the first component 20 away from the pen cap body 31. That is, the end face of the first component 20 away from the pen cap body 31 can be used as the limiting surface 203. The cooperation between the limiting surface 203 and the limiting part 321 achieves the effect of pulling the first component 20 out of the pen body 10 while removing the pen cap 30. The first component 20 can be designed as a columnar structure with uniform thickness. When installed on the outer surface of the pen body 10, the first component 20 can fit tightly against the pen body 10, making the overall structure more compact.

[0077] Please continue to refer to this. Figure 6 and Figure 7 The inner wall of the pen body 10 has a groove 103, which extends along a first direction X. In the first state, the portion of the connector 32 located between the first component 20 and the pen body 10 can be accommodated within the groove 103. During the process of removing the first component 20 from the pen body 10, the groove 103 acts as a guide, reducing the risk of the first component 20 tilting and allowing it to slide smoothly out of the pen body 10. During the installation of the first component 20, the groove 103 guides the first component 20 to a preset position, thereby positioning the first component 20.

[0078] Please continue to refer to this. Figure 6 and Figure 7 The stylus 2 may also include an elastic element 100, which has the ability to stretch and deform along a first direction X. In other words, the elastic element 100 can be stretched or compressed along the first direction X. Optionally, the elastic element 100 can be a spring. When the stylus 2 is in the first state, the elastic element 100 is located between the pen cap 30 and the first component 20. Optionally, one end of the elastic element 100 can be fixedly connected to the pen cap 30, thereby reducing the risk of loss of the elastic element 100 and improving the integration of the stylus 2. In the above state, the elastic element 100 undergoes compression deformation, and the end of the elastic element 100 away from the pen cap 30 abuts against the first component 20.

[0079] In some embodiments, the elastic member 100 can press against the first component 20, causing the end of the first component 20 away from the elastic member 100 to abut against some structural components inside the pen body 10, thereby reducing the shaking of the first component 20 and improving its stability. In other embodiments, the elastic member 100 presses against the first component 20, causing the limiting surface 203 to abut against the limiting portion 321 located at the second end of the connector 32, thereby reducing the risk of the limiting surface 203 and the limiting portion 321 disengaging, and ensuring that the first component 20 can be smoothly pulled out during the process of removing the pen cap 30.

[0080] Figure 8 A cross-sectional view of the stylus provided in this application in its first state. Figure 9 A cross-sectional view of the stylus provided in this application in a second state. (See image below.) Figure 8 and Figure 9 As shown, the first component 20 includes a first magnet 40a, and the pen body 10 includes a second magnet 40b. The first magnet 40a and the second magnet 40b can attract each other, thereby fixing the first component 20 to the outer surface of the pen body 10.

[0081] Specifically, such as Figure 8 As shown, when the stylus 2 is in the first state, the first magnet 40a and the second magnet 40b can be arranged at intervals along the first direction X, with the second magnet 40b located at the end of the first component 20 away from the pen cap 30. Thus, during the process of removing the first component 20 from the pen body 10, the first magnet 40a gradually moves away from the second magnet 40b as the first component 20 moves, and will not pass by the second magnet 40b. Therefore, the first magnet 40a and the second magnet 40b will not attract each other due to proximity, thereby reducing the resistance encountered by the first component 20 when it is removed from the pen body 10.

[0082] like Figure 9 As shown, when the stylus 2 is in the second state, the first component 20 is located on the outer surface of the pen body 10. The first component 20 and the pen body 10 can be understood as being stacked along the second direction Y. The second direction Y is perpendicular to the first direction X. In this state, the first magnet 40a and the second magnet 40b are positioned opposite each other along the second direction Y. "Opposite" means that on a plane perpendicular to the second direction Y, the orthographic projections of the first magnet 40a and the second magnet 40b at least partially overlap. The first magnet 40a and the second magnet 40b are attracted and fixed together, thereby fixing the first component 20 and the pen body 10. When it is necessary to switch the stylus 2 from the second state to the first state, by applying an external force to the first component 20 to overcome the magnetic attraction between the first magnet 40a and the second magnet 40b, the first component 20 and the pen body 10 can be separated.

[0083] In addition to fixing the first component 20 and the pen body 10 by the magnetic attraction generated by the first magnet 40a and the second magnet 40b when the stylus 2 is in the second state, at least one of the first magnet 40a and the second magnet 40b can also attract each other with the magnet correspondingly provided on the device body 1 when the stylus 2 is in the first state, thereby fixing the stylus 2 and the device body 1 in a fixed connection.

[0084] When specifically configuring the first magnet 40a and the second magnet 40b, at least one of the first magnet 40a and the second magnet 40b may include a magnet group arranged in a Hellbeck array. In some embodiments, the first magnet 40a includes a magnet group arranged in a Hellbeck array. The first magnet 40a has a strong magnetic field side and a weak magnetic field side. When the stylus 2 is in the second state, the strong magnetic field side of the first magnet 40a is located on the side of the first magnet 40a facing the pen body 10. The second magnet 40b may be a permanent magnet or a magnetic component made of soft magnetic material. The aforementioned first magnet 40a and second magnet 40b can generate a strong attraction effect, thereby improving the fixation effect between the first component 20 and the pen body 10.

[0085] Please continue to refer to this. Figure 8 and Figure 9To enhance the fixing effect between the first component 20 and the pen body 10, the first component 20 further includes a third magnet 40c, which is arranged at intervals with the first magnet 40a along the first direction X. The pen body 10 further includes a fourth magnet 40d, which is arranged at intervals with the second magnet 40b along the first direction X. The third magnet 40c and the fourth magnet 40d can attract each other, thereby enhancing the fixing effect between the first component 20 and the pen body 10.

[0086] When arranging the above magnets in a specific way, such as Figure 8 As shown, when the stylus 2 is in the first state, the third magnet 40c and the fourth magnet 40d can be arranged at intervals along the first direction X, with the fourth magnet 40d located at the end of the first component 20 away from the pen cap 30. During the process of removing the first component 20 from the pen body 10, the third magnet 40c gradually moves away from the fourth magnet 40d as the first component 20 moves, and will not pass by the fourth magnet 40d. Therefore, the third magnet 40c and the fourth magnet 40d will not attract each other due to proximity, thereby reducing the resistance encountered by the first component 20 when it is removed from the pen body 10.

[0087] Specifically, the third magnet 40c and the fourth magnet 40d are configured such that at least one of them may include a group of magnets arranged in a Helbeck array, thereby further enhancing the fixing effect between the first component 20 and the pen body 10. Details will not be elaborated here. Furthermore, in the first state, at least one of the third magnet 40c and the fourth magnet 40d can be attracted to the corresponding magnets on the device body 1, thereby enhancing the fixing effect between the stylus 2 and the device body 1.

[0088] Of course, in addition to the first magnet 40a, the second magnet 40b, the third magnet 40c and the fourth magnet 40d, one or more other magnets can be provided on the first component 20 and the pen body 10 to further enhance the fixing effect between the stylus 2 and the device body 1. This application will not go into detail.

[0089] Please continue to refer to this. Figure 9In some embodiments, the polarity of the first magnet 40a facing the pen body 10 is the same as the polarity of the fourth magnet 40d facing the first component 20, and the polarity of the third magnet 40c facing the pen body 10 is the same as the polarity of the second magnet 40b facing the first component 20. Specifically, when the first component 20 is moved to the side of the pen body 10, if the first magnet 40a and the second magnet 40b are opposite each other, and the third magnet 40c and the fourth magnet 40d are opposite each other, then the first magnet 40a and the second magnet 40b can be attracted and fixed, and the third magnet 40c and the fourth magnet 40d can be attracted and fixed, thereby fixing the first component 20 and the pen body 10 accordingly. When the two ends of the first component 20 are interchanged along the first direction X, the first magnet 40a and the fourth magnet 40d face each other, and the second magnet 40b and the third magnet 40c face each other. The first magnet 40a and the fourth magnet 40d repel each other, and the second magnet 40b and the third magnet 40c repel each other, thus preventing the first component 20 from being fixed to the surface of the pen body 10. Therefore, during the assembly of the first component 20, the correctness of its installation can be determined by the attraction and repulsion effects between the magnets, providing a foolproof method.

[0090] In the specific configuration of the first component 20, the first component 20 may include a functional device that participates in the operation of the stylus 2. For example, the functional device may be a battery cell, a circuit board, etc. Alternatively, the first component 20 may not include the aforementioned functional device. The first component 20 does not participate in the operation of the stylus 2, but is only used to form a columnar grip structure with the pen body 10. For example, the first component 20 may be a columnar shell.

[0091] like Figure 8 and Figure 9 As shown, this application uses the first component 20, including the battery cell 50, as an example for specific description. The pen body 10 includes a main circuit board 70, which is electrically connected to the battery cell 50 in a first state and a second state. The main circuit board 70 is equipped with electronic devices that can obtain electrical energy from the battery cell 50 through the main circuit board 70. As an example, the aforementioned electronic devices include, but are not limited to, sensors, processors, etc.

[0092] like Figure 8As shown, when the stylus 2 is in the first state, to electrically connect the battery cell 50 and the main circuit board 70, the first component 20 also includes a first electrical connection part 60, which is electrically connected to the battery cell 50. Optionally, the first electrical connection part 60 can be electrically connected to the battery cell 50 via a flexible circuit board, wires, etc. The pen body 10 also includes a second electrical connection part 80, which is electrically connected to the main circuit board 70. The connection method between the second electrical connection part 80 and the main circuit board 70 can refer to the connection method between the first electrical connection part 60 and the battery cell 50, and will not be described in detail here. In the first state, the first electrical connection part 60 and the second electrical connection part 80 are in contact and electrically connected, thereby electrically connecting the battery cell 50 and the main circuit board 70. In this way, the battery cell 50 can supply power to the main circuit board 70 and the electronic devices disposed on the main circuit board 70. Figure 5 In the corresponding embodiment, the elastic member 100 in the compressed state can prevent the first component 20 from shaking inside the pen body 10 by pressing against the first component 20, so that the first electrical connection part 60 and the second electrical connection part 80 make good contact and reduce the risk of poor connection.

[0093] In some specific embodiments, the first component 20 includes a protective shell, and the battery cell 50 is located inside the protective shell. The first electrical connection portion 60 includes a connecting circuit board and a spring pin mounted on the connecting circuit board. The side wall of the protective shell has a first through hole, through which the spring pin protrudes. The second electrical connection portion 80 is located on the side wall surface of the cavity of the pen body 10 for accommodating the first component 20. When the first component 20 is placed in the cavity, the spring pin can contact and be electrically connected to the second electrical connection portion 80.

[0094] like Figure 9 As shown, in the second state, the first electrical connection 60 and the second electrical connection 80 are separated, and the power supply path between the first electrical connection 60 and the second electrical connection 80 is broken. The battery cell 50 cannot supply power to the main circuit board 70 and the electronic devices disposed on the main circuit board 70 through the first electrical connection 60 and the second electrical connection 80. In this state, to ensure that the battery cell 50 and the main circuit board 70 are electrically connected, and thus allow the battery cell 50 to continue supplying power to the main circuit board 70 and the electronic devices disposed on the main circuit board 70, the outer surface of the pen body 10 has a third electrical connection 90, which is electrically connected to the main circuit board 70. Furthermore, in the second state, the third electrical connection 90 is electrically connected to the first electrical connection 60, thereby forming a current path between the battery cell 50 and the main circuit board 70. Thus, regardless of whether the stylus 2 is in the first or second state, the battery cell 50 can supply power to the main circuit board 70 inside the pen body 10 and the electronic devices disposed on the main circuit board 70, ensuring the normal use of the stylus 2.

[0095] When specifically connecting the third electrical connection part 90 and the main circuit board 70, the connection method between the first electrical connection part 60 and the battery cell 50 can be referred to, which will not be elaborated here.

[0096] When specifically designing the pen body 10, the pen body 10 includes various structural forms. Figure 10 Schematic diagrams of the structure of the stylus provided in this application in other embodiments, such as Figure 10 As shown, the pen body 10 includes a writing section 104, a grip section 105, and a receiving section 106 arranged along a first direction X. The writing section 104 is used to mount the pen tip, and the grip section 105 is located between the writing section 104 and the receiving section 106. The receiving section 106 has a cavity for accommodating a first component 20. In a first state, the first component 20 is accommodated within the cavity of the receiving section 106. In a second state, at least a portion of the first component 20 is fixedly connected to the outer surface of the grip section 105, and together with the grip section 105, forms a columnar grip structure.

[0097] Because the grip portion 105 is close to the tip of the stylus 2, the grip structure formed by the splicing of the first component 20 and the grip portion 105 is also close to the tip of the stylus 2, thus conforming to human writing habits. In addition, the grip portion 105 can accommodate the main circuit board 70, electronic components, the second magnet 40b, and the fourth magnet 40d, etc., so that the disassembly and assembly of the first component 20 has little impact on the above-mentioned components.

[0098] In a specific implementation, the first component 20 can be fixed as a whole to the outer surface of the grip portion 105, thereby assembling with the grip portion 105 to form a columnar grip structure. Alternatively, the first component 20 can be partially fixed to the surface of the grip portion 105 and the other part fixed to the surface of the receiving portion 106.

[0099] Figure 11 for Figure 10 The diagram shown is a cross-sectional view of the stylus at the receiving part and the grip part, as shown in the figure. Figure 11 As shown, the solid line represents the cross-section of the receiving portion 106, and the dashed line represents the cross-section of the grip portion 105. The cross-sectional area of ​​the receiving portion 106 is larger than that of the grip portion 105. All of these cross-sections are perpendicular to the first direction X. That is, along the length of the pen body 10, the thickness of the pen body 10 is uneven, with the receiving portion 106 being thicker than the grip portion 105. By making the receiving portion 106 thicker, it is easier for the first component 20 to be placed within the cavity of the receiving portion 106. Optionally, the receiving portion 106 and the grip portion 105 are smoothly connected.

[0100] In a specific configuration, the thickness H1 of the receiving portion 106 along the second direction Y and the thickness H2 of the gripping portion 105 along the second direction Y are substantially equal. The maximum width W1 of the receiving portion 106 along the third direction Z is greater than the maximum width W2 of the gripping portion 105 along the third direction Z. The maximum width of the gripping portion 105 along the third direction Z and the maximum width of the first component 20 along the third direction Z are substantially equal.

[0101] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
