Description

TECHNICAL AREA

[0001] The present application relates to the technical field of input pens, in particular a battery module for an input pen, a pen body of an input pen, an input pen and a touch input device. STATE OF THE ART

[0002] Currently, various touch input devices and interactive systems are widely used. For example, the interaction between a stylus and a touchscreen allows the user to put the stylus into a writing mode or an erase mode. In writing mode, the user can use the stylus to perform writing or drawing operations such as writing or drawing on the touchscreen, while in erase mode, content such as notes or drawings can be deleted.

[0003] Styluses typically contain a battery. With increasing use, the battery is at risk of damage. However, due to the design of most styluses currently on the market, users cannot replace the battery themselves, meaning that a new stylus must be purchased if the battery fails, increasing usage costs. CONTENT OF THE PRESENT APPLICATION

[0004] The present application provides a battery module for a stylus, a stylus body, a stylus and a touch input device, thereby solving the problem in the relevant technology where users cannot replace damaged batteries due to structural limitations of the stylus, resulting in waste.

[0005] First, the embodiment of the present application provides a battery module for an input pen; the battery module comprises a housing and a battery arranged in a receiving space of the housing, wherein the housing is designed to be detachably connected to the pen body of the input pen, and wherein, when the housing is mounted on an outer housing of the pen body, the battery is configured to cooperate with the control component of the pen body to supply power to the control component of the pen body.

[0006] Secondly, an embodiment of the present application provides a pen body of an input pen; the pen body comprises an outer casing and a control component arranged in a cavity of the outer casing, wherein the outer casing is configured to be detachably connected to a battery module for an input pen, and wherein the control component is configured to cooperate with a battery of the battery module to receive electrical energy supplied by the battery of the battery module when the outer casing is mounted on a casing of the battery module.

[0007] Thirdly, the embodiment of the present application provides an input pen; this input pen comprises the above-mentioned battery module and the above-mentioned pen body.

[0008] Fourthly, the embodiment of the present application provides a touch input device; this touch input device comprises a touchscreen and the aforementioned stylus.

[0009] In battery modules for styluses, stylus bodies, styluses, and touch input devices according to the embodiments of this application, the stylus is divided into two independent battery modules and the stylus body. The battery module and the stylus body are detachably connected. If the battery is damaged, the user can simply remove and replace the battery module without having to discard the entire stylus. This effectively reduces operating costs. Similarly, if the stylus body is damaged, the user only needs to remove and replace the stylus body without having to discard the entire stylus, which effectively reduces operating costs.

DETAILED DESCRIPTION

[0012] To clarify the purpose, technical solution, and advantages of this application, it is explained in detail below with reference to the attached figures and embodiments. It should be noted that the specific embodiments described herein serve only to illustrate this application and are not intended to limit it.

[0013] As in Fig. The touch input device shown (not shown in the figure) can include products, but is not limited to tablets, electronic graphics tablets, learning computers, game consoles, etc.

[0014] The touch input device includes a stylus 10 and a touchscreen (not shown in the figure).

[0015] The stylus 10 has various operating modes, including the write mode and the erase mode.

[0016] When the tip of the stylus 10 touches the touch surface of the touchscreen, the stylus 10 is in write mode. In this mode, the tip electrode of the stylus 10 sends a downlink signal to the touchscreen, allowing it to detect the stylus's position on the touchscreen and display the corresponding stroke. This enables the user to perform writing tasks such as taking notes or drawing on the touchscreen using the stylus 10. When the rear end of the stylus 10 touches or approaches the touch surface of the touchscreen, the stylus 10 is in erase mode. In this mode, the rear electrode of the stylus 10 sends another downlink signal to the touchscreen, allowing it to detect the stylus's position on the touchscreen and erase the corresponding stroke.In this way, the user can, for example, delete notes or drawings on the touchscreen using the stylus 10.

[0017] As in the Fig. As shown in Figures 1 to 4, the input pen 10 comprises a battery module 100 and a pen body 200. The specific structure of the battery module 100 and the pen body 200 is explained in more detail below.

[0018] The battery module 100 comprises a housing 110 and a battery 120.

[0019] The housing 110 functions as a housing component of the battery module 100. The specific material composition of the housing 110 is not restricted here, and the design personnel can make an appropriate selection according to the actual requirements; for example, the material of the housing 110 can be, but is not limited to, plastic, silicone, or rubber, etc.

[0020] Housing 110 has a receiving space 110a, wherein the receiving space 110a represents the cavity within the housing 110. The specific shape of the receiving space 110a is not limited here, and the design personnel can reasonably shape it according to the actual requirements; for example, the shape of the receiving space 110a can be adapted to the outer contour shape of the battery 120.

[0021] The battery 120 is configured as the power source of the battery module 100 in such a way that it supplies power to the control component 220 of the pen body 200.

[0022] The battery 120 is located in the receiving space 110a of the housing 110. The specific installation method between the battery 120 and the housing 110 is not restricted here; the design personnel can adapt it appropriately according to actual requirements. For example, a battery installation groove may be provided in the receiving space 110a of the housing 110, into which the battery 120 is inserted; alternatively, a battery installation seat may be provided in the receiving space 110a of the housing 110, on which the battery 120 is mounted.

[0023] The housing 110 is configured to be detachably connected to the pen body 200 of the input pen 10, thus enabling a detachable connection between the entire battery module 100 and the pen body 200 of the input pen 10. This allows the user to replace the battery module 100 with a discharged or damaged battery, or the damaged pen body 200, in a timely manner. The specific types of detachable connections between the housing 110 and the pen body 200 of the input pen 10 are not limited here.Designers can implement an appropriate design according to actual requirements; for example, the detachable connection between the housing 110 and the pin body 200 of the input stylus 10 (in particular the outer housing 210 of the pin body 200) can be achieved by a threaded connection; or the housing 110 and the pin body 200 of the input stylus 10 (in particular the outer housing 210 of the pin body 200) can be detachably connected to each other by a snap-fit ​​connection; furthermore, the detachable connection between the housing 110 and the pin body 200 of the input stylus 10 (in particular the outer housing 210 of the pin body 200) can also be made by a plug connection; in addition, the detachable connection between the housing 110 and the pin body 200 of the input stylus 10 (in particular the outer housing 210 of the pin body 200) can also be achieved by magnetic attraction.

[0024] When the housing 110 is mounted on the outer housing 210 of the pen body 200, the battery 120 is configured to interact with the control component 220 of the pen body 200 to supply power to the control component 220 of the pen body 200; when the housing 110 is removed from the outer housing 210 of the pen body 200, the battery 120 stops supplying power to the control component 220 of the pen body 200. It should be explained that the battery 120 can supply power to the control component 220 of the pen body 200 via wired charging; for example, in this case, an electrical connection between the battery 120 and the control component 220 of the pen body 200 can be established through the interaction of electrical contacts and contact surfaces.The battery 120 can also supply power to the control components 220 of the pen body 200 via wireless charging; for example, in this case, an electrical connection between the battery 120 and the control components 220 of the pen body 200 can be established by the interaction of a wireless transmitting coil and a wireless receiving coil.

[0025] By designing the input pen 10 as two independent modules—the battery module 100 and the pen body 200—with the battery module 100 being detachably connected to the pen body 200, the user can, if the battery 120 is damaged, simply remove and replace the battery module 100 without having to discard the entire input pen 10. This effectively reduces operating costs for the user. Similarly, if the pen body 200 is damaged, only it needs to be removed and replaced without having to discard the entire input pen 10, which also effectively reduces operating costs.

[0026] The housing 110 and the side wall of the rear end of the outer housing 210 form an interlocking inner-outer nesting structure. For example, the housing 110 can enclose the side wall of the rear end of the outer housing 210, in which case the housing 110 encloses the outer housing 210 of the pin body 200; another example would be that the housing 110 is enclosed by the side wall of the rear end of the outer housing 210, in which case the outer housing 210 of the pin body 200 encloses the housing 110; furthermore, the housing 110 can also enclose the side wall of the rear end of the outer housing 210 and simultaneously be itself enclosed by the side wall of the rear end of the outer housing 210, thus forming a multi-layered inner and outer nesting structure between the housing 110 and the outer housing 210 of the pin body 200.It should be noted that “the housing 110 is enclosed by the side wall of the rear end of the outer housing 210” can mean that the entire housing 110 projects into the receiving space 110a of the outer housing 210, or that only part of the housing 110 projects into the receiving space 110a of the outer housing 210, while the remaining part of the housing 110 projects out of the receiving space 110a of the outer housing 210.

[0027] As in the Fig. As shown in Figures 4 to 6, the housing 110 comprises an end wall 111 and a circumferential wall 112 arranged around the end wall 111, the end wall 111 being connected to the circumferential wall 112 to enclose a receiving space 110a configured to receive the aforementioned battery 120. The circumferential wall 112 is arranged around the central axis of the input stylus 10, while the end wall 111 is arranged along the direction in which the central axis of the input stylus 10 runs.

[0028] When the housing 110 is connected to the outer housing 210 of the pin body 200 by a snap connection; the battery module 100 further comprises a snap element 130 which is connected to the circumferential wall 112, the snap element 130 being configured to interact with the snap groove 210a on the side wall of the outer housing 210 to position the housing 110 on the outer housing 210 of the pin body 200 and thereby enable assembly between the battery module 100 and the pin body 200.

[0029] The detent element 130 is the component that interacts with the detent groove 210a to define the relative position between the housing 110 and the outer housing 210 of the pin body 200. The specific type of connection between the detent element 130 and the circumferential wall 112 is not restricted here.Designers can adapt them to the actual requirements. For example, the locking element 130 can be detachably connected to the circumferential wall 112, and not exclusively by at least one of the following methods: screwing, snap-fit, or plug connection. Another example: The locking element 130 can also be permanently connected to the circumferential wall 112, for example by bonding, injection molding, or 3D printing, although these methods are not the only possibilities. It is understood that the specific embodiment of the locking element 130 can be manifold, and the specific connection method between the locking element 130 and the circumferential wall 112 will differ for different embodiments of the locking element 130.For example, the locking element 130 can comprise a locking block (not shown in the figure) which is formed into an integral structure with the circumferential wall 112 by injection molding or 3D printing, wherein the locking block engages with the locking groove 210a to achieve a relative positional fixation between the housing 110 and the outer housing 210 of the pin body 200;Alternatively, the locking element 130 can, for example, also comprise a wedge block (not shown in the figure) and a spring (not shown in the figure), wherein the circumferential wall 112 is provided with a groove (not shown in the figure) corresponding to the locking groove 210a of the outer housing 210, the wedge block is slidably connected to the groove, and the spring is arranged in the groove, with both ends being fixedly connected to the wedge block and the groove bottom, respectively, so that the wedge block locks into the locking groove 210a to achieve a relative position fixation between the housing 110 and the outer housing 210 of the pin body 200.

[0030] The design of the locking element 130, which interacts with the locking groove 210a on the side wall of the outer housing 210, achieves a relative positional fixation between the housing 110 and the outer housing 210 of the pin body 200, thereby mounting the battery module 100 in the pin body 200. This structure is simple and easy to implement.

[0031] More precisely, as in the Fig. As shown in Figures 4 to 6, a release groove 112a is provided in the circumferential wall 112, which corresponds to a detent groove 210a of the outer housing 210; the detent element 130 comprises a connecting part 131 and a detent spring leaf 132, wherein the connecting part 131 is connected to the circumferential wall 112 and the detent spring leaf 132 is arranged according to the release groove 112a and is connected to the connecting part 131; when the housing 110 is positioned in the outer housing 210 of the pin body 200, the detent spring leaf 132 engages with the detent groove 210a of the outer housing 210.

[0032] Here, the connecting part 131 serves as an intermediate connection structure between the detent spring leaf 132 and the circumferential wall 112. The specific type of connection between the connecting part 131 and the circumferential wall 112 is not restricted here;Designers can adapt them to the actual requirements. For example, the connecting part 131 can be detachably connected to the circumferential wall 112, and not exclusively by at least one of the following methods: screwing, snap-fit, or plug connection. Another example: The connecting part 131 can also be permanently connected to the circumferential wall 112, for example by bonding, injection molding, or 3D printing, although these methods are not the only possibilities. It is understood that the specific embodiment of the connecting part 131 can be manifold, and the specific connection method between the connecting part 131 and the circumferential wall 112 will differ for different embodiments of the connecting part 131.For example, the connecting part 131 can comprise a connecting projection (not shown in the figure), wherein the circumferential wall 112 near the clearance groove 112a is provided with a positioning groove (not shown in the figure), and the connecting projection interacts with the positioning groove to position the detent spring leaf 132 on the circumferential wall 112; alternatively, the connecting part 131 can, for example, also comprise a screw (not shown in the figure), wherein the circumferential wall 112 near the clearance groove 112a is provided with a threaded hole (not shown in the figure), and the screw is guided through the detent spring leaf 132 and is connected to the threaded hole to position the detent spring leaf 132 on the circumferential wall 112.

[0033] The detent spring leaf 132 is elongated and configured to deform elastically under force and to return to its original shape after the force is removed. A clearance groove 112a corresponding to the detent spring leaf 132 is provided in the circumferential wall 112, offering sufficient deformation space and enabling good elastic deformation. This strengthens the connection between the housing 110 and the outer housing 210 of the pin body 200 and facilitates disassembly between the housing 110 and the outer housing 210 of the pin body 200.

[0034] More specifically, as in the Fig. As shown in Figures 4 to 6, the connecting part 131 comprises a connecting ring 1311. The connecting ring 1311 rests against the circumferential wall 112, and the annular surface of the connecting ring 1311 has a through-groove 1311a, which corresponds to the clearance groove 112a. The detent spring 132 is arranged according to the through-groove 1311a and is firmly connected to the connecting ring 1311. The connecting ring 1311 and the detent spring 132 are formed in one piece. By designing the connecting part 131 as a connecting ring 1311, the contact area between the connecting ring 1311 and the circumferential wall 112 is increased, thereby improving the connection stability between the detent element 130 and the circumferential wall 112. Due to its larger volume, the connecting ring 1311 provides good support for the detent spring 132.Additionally, the connecting ring 1311 can be configured as a reinforcing body to improve the structural strength of the circumferential wall 112.

[0035] The connecting ring 1311 has a recess 1311b. The design of the recess 1311b allows the radial dimension of the connecting ring 1311 to be changed under the influence of an external force in order to facilitate the assembly and disassembly of the locking element 130 on the circumferential wall 112.

[0036] Of course, in other embodiments, if the housing 110 is in snap-fit ​​connection with the outer housing 210 of the pin body 200, it is also possible that the circumferential wall 112 is provided with a snap-fit ​​groove 210a configured to interact with a snap-fit ​​element 130 of the pin body 200 to position the housing 110 on the outer housing 210 of the pin body 200, thereby enabling the mounting of the battery module 100 on the pin body 200. It is worth mentioning that the specific embodiment of the snap-fit ​​element 130 arranged on the outer housing 210 of the pin body 200 can be described in the preceding introduction of the snap-fit ​​element 130, which will not be discussed further here.

[0037] As in Fig. As shown in Figure 6, the battery 120 is removable from the compartment 110a of the housing 110. If the battery 120 is a dry cell battery, the user can remove the discharged or damaged dry cell battery 120 directly from the compartment 110a of the housing 110 and replace it with a new dry cell battery 120. This is easy to handle, so the user does not have to dispose of the entire battery module 100 because of a discharged or damaged dry cell battery 120, which further reduces the user's operating costs. If the battery 120 is a lithium battery 120, the user can remove the damaged lithium battery 120 directly from the compartment 110a of the housing 110 and replace it with a new lithium battery 120.This is easy to handle, so the user does not have to dispose of the entire battery module 100 because of a damaged lithium battery 120, which further reduces the user's operating costs.

[0038] In particular, the housing 110 comprises a sleeve body 113 and a cover 114, wherein at least a portion of the sleeve body 113 is enclosed by a side wall of the outer housing 210, and wherein the cover 114 is movably connected to the sleeve body 113 to open or close a sleeve opening of the sleeve body 113, and wherein the cover 114 and the sleeve body 113 together enclose a receiving chamber 110a. The specific movable connection between the cover 114 and the sleeve body 113 is not restricted; designers can design it appropriately according to actual requirements. For example, the cover 114 can be movably connected to the sleeve body 113, and not exclusively by a pivot axis. Another example: The cover 114 can also be movably connected to the sleeve body 113, for instance by a tongue-and-groove connection, although these methods are not considered the only possibilities.Due to the design of the cover 114 and the sleeve body 113 in a movable connection, the cover 114 moves relative to the sleeve body 113 to open or close the opening of the sleeve body 113, thus enabling the installation and removal of the battery 120, resulting in a simple structure and convenient operation. Of course, the cover 114 can be configured in other embodiments, as shown in... Fig. 7 shown, also securely connected to the sleeve body 113 via the locking mechanism 115.

[0039] As in Fig. 4 to Fig. As shown in Figure 6, the battery module 100 further comprises a connector 140, which is attached to the housing 110 and electrically connected to the battery 120. The connector 140 is configured such that, when the housing 110 is positioned on the outer casing 210 of the pin body 200, it is inserted into a connector 222 of the control component 220 to establish an electrical connection to the connector 222 of the control component 220. The design of the connector 140 ensures that, when the housing 110 is positioned on the outer casing 210 of the pin body 200, the electrical connection is established by connecting the connector 140 to the connector 222 of the control component 220.In contrast to a method where electrical contacts and conductor tracks directly interact to establish the electrical connection, the plug connection between terminal 140 and connector 222 of the control component 220 can compensate for problems with poor electrical contact caused by assembly errors along the axis of the input pin 10. It is worth noting that there is not only an electrical connection between terminal 140 and connector 222 of the control component 220, but also a structural connection. Together with the interaction between the aforementioned locking element 130 and the locking groove 210a, this enables a double fastening between the housing 110 and the outer housing 210 of the pin body 200, effectively increasing the connection stability between the battery module 100 and the pin body 200.

[0040] Specifically, terminal 140 is mounted on the cover 114. A first electrical connection element (not shown in the figure, e.g., a conductive ring) is embedded in the end face of the cover 114 facing the sleeve body 113 and is electrically connected to terminal 140. A second electrical connection element (not shown in the figure, e.g., another conductive ring) is embedded in the end face of the sleeve body 113 facing the cover 114 and is electrically connected to the circuit board 150 of the battery module 100. When the cover 114 closes the sleeve opening of the sleeve body 113, the first and second electrical connections make contact, thus closing the circuit between the battery 120 and terminal 140.

[0041] Interface 140 can include a plug that is electrically connected to battery 120, and connector 222 can include a socket that is electrically connected to the main board 221 of control component 220. When housing 110 is positioned on the outer housing 210 of the pin body 200, the plug serving as interface 140 is inserted into the socket serving as connector 222. Of course, interface 140 can also include a socket that is electrically connected to battery 120, and connector 222 can also include a plug that is electrically connected to the main board 221 of control component 220. When housing 110 is positioned on the outer housing 210 of pin body 200, the socket serving as interface 140 is inserted into the plug serving as connector 222.

[0042] Along the insertion direction of the plug and socket, the engagement depth with which the plug interacts with the socket is greater than or equal to 1.5 mm and less than or equal to 3.0 mm. For example, the engagement depth with which the plug and socket interact can be, but is not limited to: 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3.0 mm, etc. Here, the "engagement depth" is understood as the overlapping length of the plug's pin connections and the socket's pin connections along the center line of the input pin 10.By ensuring a reasonable design of the interaction depth between plug and socket, it is ensured that the plug can be connected to the socket and that effective contact is made between the pin terminals of the plug and the pin terminals of the socket, even if assembly deviations occur along the direction of the central axis of the input pen 10 when assembling the battery module 100 and the pen body 200.

[0043] As in Fig. 1 to Fig. As shown in Figure 4, the pin body 200, which can be detachably connected to the battery module 100, comprises an outer housing 210 and a control component 220.

[0044] The outer casing 210 serves as a housing component of the pen body 200. The specific material of the outer casing 210 is not specified here; designers may make an appropriate selection according to practical requirements. For example, the material of the outer casing 210 may be, among others, plastic, silicone, or rubber.

[0045] The outer casing 210 has a cavity 210b, wherein the cavity 210b is the inner cavity of the outer casing 210. The specific shape of the cavity 210b is not restricted here; the designer may make an appropriate design according to the actual requirements; for example, the shape of the cavity 210b may be, among other things, but not limited to, that of a cylindrical body.

[0046] The control component 220 serves as the control center of the pen body 200, with the control component 220 being configured to control the operating mode of the input pen 10.

[0047] The specific structure of tax component 220 is explained in more detail below.

[0048] The control component 220 is located in the cavity 210b of the outer housing 210. The specific installation method between the control component 220 and the outer housing 210 is not restricted here; designers can make an appropriate design based on the actual requirements; for example, an installation bracket can be provided in the cavity 210b of the outer housing 210, and the control component 220 is then mounted on the installation bracket.

[0049] The outer casing 210 is configured to be detachably connected to the battery module 100 of the input pen 10. This creates a detachable connection between the entire pen body 200 and the battery module 100 of the input pen 10, allowing the user to replace the pen body 200, whose battery is empty or damaged, or the damaged battery module 100 in a timely manner. The specific types of detachable connections between the outer casing 210 and the battery module 100 of the input pen 10 are not limited here.Designers can implement an appropriate design according to actual requirements; for example, the detachable connection between the outer housing 210 and the battery module 100 of the input pen 10 (in particular the housing 110 of the battery module 100) can be achieved by a threaded connection; or the outer housing 210 and the battery module 100 of the input pen 10 (in particular the housing 110 of the battery module 100) can be detachably connected to each other by a snap-fit ​​connection; furthermore, the detachable connection between the outer housing 210 and the battery module 100 of the input pen 10 (in particular the housing 110 of the battery module 100) can also be made by a plug connection; in addition, the detachable connection between the outer housing 210 and the battery module 100 of the input pen 10 (in particular the housing 110 of the battery module 100) can also be achieved by magnetic attraction.

[0050] When the outer casing 210 is mounted on the casing 110 of the battery module 100, the control component 220 is configured to interact with the battery 120 of the battery module 100 to receive the electrical energy supplied by the battery 120 of the battery module 100; when the outer casing 210 is removed from the casing 110 of the battery module 100, the battery 120 of the battery module 100 stops supplying power to the control component 220. It should be explained that the control component 220 can receive the electrical energy supplied by the battery 120 of the battery module 100 via wired charging; for example, in this case, an electrical connection between the control component 220 and the battery 120 of the battery module 100 can be established through the interaction of electrical contacts and contact surfaces.The control component 220 can also receive the electrical energy provided by the battery 120 of the battery module 100 via wireless charging; for example, in this case, an electrical connection between the control component 220 and the battery 120 of the battery module 100 can be established by the interaction of a wireless transmitting coil and a wireless receiving coil.

[0051] The side wall of the rear end of the outer casing 210 and the casing 110 of the battery module 100 form an interlocking inside-outside nesting structure. For example, the side wall of the rear end of the outer casing 210 can enclose the casing 110 of the battery module 100, with the outer casing 210 then enclosing the casing 110 of the battery module 100; another example would be that the side wall of the rear end of the outer casing 210 is enclosed by the casing 110 of the battery module 100, with the casing 110 of the battery module 100 then enclosing the outer casing 210; Furthermore, the side wall of the rear end of the outer casing 210 can also enclose the housing 110 of the battery module 100 and at the same time be enclosed by the housing 110 of the battery module 100, whereby the outer casing 210 and the housing 110 of the battery module 100 form a multi-layered inner and outer nesting.It should be noted that “the side wall of the rear end of the outer casing 210 encloses the casing 110 of the battery module 100” can mean that the entire casing 110 protrudes into the receiving space 110a of the outer casing 210, or that only part of the casing 110 protrudes into the receiving space 110a of the outer casing 210, while the remaining part of the casing 110 protrudes out of the receiving space 110a of the outer casing 210.

[0052] As in the Fig. Figures 4 to 6 show the outer housing 210 in a snap-fit ​​connection with the housing 110 of the battery module 100. The side wall of the outer housing 210 can also be provided with a snap-fit ​​groove 210a configured to interact with a snap-fit ​​element 130 of the battery module 100 to position the outer housing 210 on the housing 110 of the battery module 100, thereby enabling the mounting of the pin body 200 on the battery module 100. It is worth noting that the specific embodiment of the snap-fit ​​element 130 can be found in the preceding introduction, which will not be discussed further here.

[0053] When the outer housing 210 is in snap-fit ​​connection with the housing 110 of the battery module 100, the pin body 200 also includes a locking element 130, which is connected to the side wall of the outer housing 210 and is configured to interact with a locking groove 210a of the housing 110 to position the outer housing 210 on the housing 110 of the battery module 100, thereby achieving the mounting of the pin body 200 on the battery module 100. It is worth noting that the specific embodiment of the locking element 130 can be found in the preceding introduction, which will not be discussed further here.

[0054] As in Fig. As shown in Figure 4, the control component 220 comprises a mainboard 221 and a connector 222. The mainboard 221 is mounted in the cavity 210b of the outer housing 210. The connector 222 is located at the end of the mainboard 221 facing the rear end of the outer housing 210 and is electrically connected to the mainboard 221. The connector 222 is configured such that, when the outer housing 210 is positioned on the housing 110 of the battery module 100, it is inserted into the terminal 140 of the battery module 100 to establish an electrical connection. In this configuration, the mainboard 221 controls the operating mode of the input stylus 10 and can be mounted on the aforementioned holder, while the connector 222 can be soldered directly onto the mainboard 221.The design of connector 222 establishes an electrical connection when the outer housing 210 is positioned on the housing 110 of the battery module 100, by connecting connector 222 to terminal 140 of the battery module 100. Compared to a method where electrical contacts and conductor tracks directly interact to establish the electrical connection, the plug connection between connector 222 and terminal 140 of the battery module 100 can compensate for problems with poor electrical contact caused by mounting deviations along the axis of the input pin 10. It is worth noting that there is not only an electrical connection but also a structural connection between connector 222 and terminal 140 of the battery module 100.Together with the interaction between the above-mentioned locking element 130 and the locking groove 210a, this enables a double fastening between the outer housing 210 and the housing 110 of the battery module 100, in order to effectively increase the connection stability between the pin body 200 and the battery module 100.

[0055] Connector 222 can include a plug that is electrically connected to the mainboard 221, and interface 140 can include a socket that is electrically connected to the battery 120 of the battery module 100. When the outer housing 210 is positioned on the housing 110 of the battery module 100, the plug serving as connector 222 is inserted into the socket serving as interface 140. Of course, connector 222 can also include a socket that is electrically connected to the mainboard 221, and interface 140 can likewise include a plug that is electrically connected to the battery 120 of the battery module 100. When the outer housing 210 is positioned on the housing 110 of the battery module 100, the socket serving as connector 222 is inserted into the plug serving as interface 140.

[0056] As in Fig.As shown in Figure 8, a guide chamfer 222a is provided at the insertion opening of the socket serving as connector 222. Due to the design of the guide chamfer 222a, it acts as a guide for the plug serving as connection 140. This promotes the locking of the socket with the plug and reduces wear on both.
