[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] The following is combined with Figures 1 to 10 The following describes embodiments of the present invention.
[0034] According to an embodiment of the present invention, an electronic pen is provided, comprising a pen barrel 20 and a pen refill module 30 and a battery module 10 disposed within the pen barrel 20. The battery module 10 is located on one side of the pen refill module 30 along a first direction X, and is connected to the pen refill module 30.
[0035] Understandably, such as Figure 1-3 The first direction X can be the length direction of the electronic pen, that is, the axial direction of the pen barrel 20. The second direction Y intersects the first direction X. In some cases, the second direction Y is perpendicular to the first direction X. The second direction Y is the radial direction of the electronic pen.
[0036] Understandably, the pen barrel 20 has a pen tip and a pen tail, both with openings. The pen refill module 30 is positioned near the pen tip, and the battery module 10 is positioned near the pen tail. The battery module 10 can be inserted into the pen barrel 20 through the opening at the pen tail and connected to the pen refill module 30. The battery module 10 and the pen refill module 30 can be fixedly connected or detachably connected. For example, the battery module 10 and the pen refill module 30 are detachably connected, and after the battery module 10 is separated from the pen refill module 30, the battery module 10 can detach from the pen barrel 20 through the opening at the pen tail.
[0037] Furthermore, such as Figure 4-6 As shown, the battery module 10 includes a first tube 1 and a battery assembly 3, a charging assembly 2, and a telescopic assembly 4 disposed within the first tube 1. The battery assembly 3, the telescopic assembly 4, and the charging assembly 2 are arranged sequentially along the first direction X, with the telescopic assembly 4 connecting the battery assembly 3 and the charging assembly 2.
[0038] Furthermore, the charging assembly 2 includes a charging element 21, which is electrically connected to the battery assembly 3, and the charging element 21 has an interface portion 211. The charging assembly 2 is movably disposed along a first direction X, such that the interface portion 211 has a concealed state located inside the first tube body 1 and an exposed state located outside the first tube body 1. The telescopic assembly 4 is telescopically disposed along the first direction X, and the telescopic assembly 4 is adapted to move the charging assembly 2 between the concealed state and the exposed state when it extends or retracts.
[0039] Understandably, the battery module 10 is disposed within the pen barrel 20 of the electronic pen, that is, the first tube 1 of the battery module 10 is disposed within the pen barrel 20. In the exposed state, the interface portion 211 of the charging component 2 is exposed outside the first tube 1 and the pen barrel 20. Preferably, the battery component 3 is disposed near the pen core module 30, and the charging component 2 is disposed near the pen tail, so that the interface portion 211 is exposed.
[0040] In this embodiment, the battery component 3 and the charging component 2 of the battery module 10 are integrated into a single structure via the first tube 1, facilitating the assembly of the electronic pen. Furthermore, the charging component 2 utilizes the telescopic extension of the telescopic component 4 to move along the first direction X, allowing the interface portion 211 to switch between a hidden state and an exposed state. In the hidden state, the interface portion 211 of the charging component 2 is concealed within the first tube 1, improving aesthetics and providing dust and impact protection, thus enhancing durability. In the exposed state, the interface portion 211 of the charging component 2 is exposed, allowing charging of the battery component 3 through the interface portion 211. Therefore, in the battery module 10 and the electronic pen using it of this invention, the integrated design of the battery module 10 facilitates assembly and provides both charging functionality and the ability to conceal the interface portion 211, resulting in good aesthetics and durability.
[0041] Understandably, the telescopic component 4 of this utility model can be any structural component with linear telescopic function, as long as it can be installed inside the first tube 1 to achieve the telescopic function.
[0042] In some embodiments, such as Figures 7-9 As shown, the telescopic component 4 specifically includes a limiting member 41, a sliding connector 42, and an elastic member 43. The limiting member 41 is connected to the battery assembly 3. A first receiving cavity 411 is formed within the limiting member 41, and a locking portion 412 is provided within the first receiving cavity 411. One end of the sliding connector 42 is slidably connected to the first receiving cavity 411 along a first direction X, and the other end is connected to the charging assembly 2. It can be understood that, as Figure 5 and Figure 6As shown, when the sliding connector 42 slides along the first direction X away from the limiting member 41, that is, the telescopic component 4 extends, the sliding connector 42 can push the charging component 2 to move until the interface 211 is exposed; when the sliding connector 42 slides along the first direction X towards the limiting member 41, that is, the telescopic component 4 shortens, the sliding connector 42 pulls to move the charging component 2 until the interface 211 is hidden. The elastic member 43 is located in the first receiving cavity 411 and is connected to the sliding connector 42. The elastic member 43 is used to drive the charging component 2 to move through the sliding connector 42, so that the interface 211 switches from the hidden state to the exposed state.
[0043] The sliding connector 42 has a locked state and an unlocked state. In the locked state, at least a portion of the structure of the sliding connector 42 abuts against the locking portion 412 to restrict the charging assembly 2 and lock the interface portion 211 in a hidden state. In the unlocked state, the sliding connector 42 disengages from the locking portion 412 to allow the charging assembly 2 to move. Under the action of the elastic member 43, the interface portion 211 can switch from a hidden state to an exposed state. The charging assembly 2 is adapted to switch the sliding connector 42 between the locked and unlocked states when pressed.
[0044] In this embodiment, such as Figure 6 As shown, when the interface portion 211 of the charging component 2 is in the hidden state, the sliding connector 42 is in the locked state, and the charging interface of the charging component 2 is hidden inside the first tube 1. When charging is required, the charging component 2 is pressed, causing the sliding connector 42 to switch from the locked state to the unlocked state. Under the action of the elastic member 43, the sliding connector 42 extends and moves the charging component 2, and the interface portion 211 switches from the hidden state to the exposed state and remains in the exposed state. At this time, the charging interface of the charging component 2 is exposed so that charging can be performed. When charging is complete, the charging component 2 is pressed again, and the pressing force overcomes the elastic force of the elastic member 43. The sliding connector 42 shortens and moves the charging component 2 from the exposed state to the hidden state, and the sliding connector 42 switches from the unlocked state to the locked state, locking the charging component 2 in the hidden state. In the technical solution of this embodiment, the extension and retraction of the interface portion 211 can be achieved by pressing, which is simple and convenient to operate and provides a good user experience.
[0045] Specifically, such as Figure 5As shown, the battery assembly 3 includes a third support member 31 and a battery 32 and a circuit board 33 disposed within the third support member 31. The aforementioned limiting member 41 is connected to the third support member 31, specifically, the limiting member 41 is connected to the end of the third support member 31 away from the pen refill module 30 along the first direction X. The limiting member 41 and the third support member 31 can be fixedly connected or detachably connected, such as by adhesive, snap-fit, or threaded connection. For example, the limiting member 41 and the third support member 31 are snapped together by a first snap-fit structure 5, which includes a first snap-fit groove and a first snap-fit block. For example, the third support member 31 has a first protruding post protruding towards the limiting member 41, and a first snap-fit block is provided on the outer periphery of the first protruding post; the limiting member 41 has a first snap-fit groove, the first protruding post passes through the first receiving cavity 411, and the first snap-fit block engages with the first snap-fit groove. Alternatively, in some embodiments not shown in the figures, the first card block may be disposed on the limiting member 41, and the first card slot may be disposed on the third support member 31.
[0046] Furthermore, in some embodiments, the sliding connector 42 includes a pivot 421 and a rotating member 422. The pivot 421 is slidably disposed within the first receiving cavity 411 along a first direction X. The pivot 421 has a first end 4211 and a second end 4212 disposed opposite to each other along the first direction X. The first end 4211 of the pivot 421 is located within the first receiving cavity 411, and the second end 4212 is connected to the charging assembly 2. The first end 4211 is provided with a driving portion 4213. The rotating member 422 is rotatably sleeved on the first end 4211 and engages with the driving portion 4213. The outer periphery of the rotating member 422 is provided with a first protrusion 4221. In the locked state, the first protrusion 4221 abuts against the locking part 412 to restrict the movement of the rotating member 422 along the first direction X, and with the cooperation of the elastic member 43, restricts the sliding of the shaft member 421 along the first direction X, thereby restricting the sliding of the entire sliding connector 42 along the first direction X, thus restricting the movement of the charging component 2 and keeping the interface part 211 in the hidden state. In the unlocked state, the first protrusion 4221 disengages from the locking part 412 to allow the rotating member 422 to move along the first direction X, and with the action of the elastic member 43, drives the rotating member 422 and the shaft member 421 to slide along the first direction X, thereby pushing out the charging component 2, switching the interface part 211 from the hidden state to the exposed state, and keeping it in the exposed state with the action of the elastic member 43.
[0047] When the pivot 421 slides along the first direction X, the rotating member 422 is adapted to rotate around its own axis under the pressure of the driving part 4213, so that the first protrusion 4221 abuts against or disengages from the locking part 412. That is, by pressing the charging component 2, the driving part 4213 of the pivot 421 abuts against the rotating member 422, thereby realizing the switching between the locked and unlocked states of the sliding connector 42. In this embodiment, the pivot 421 and the rotating member 422 mesh together to realize the switching between the locked and unlocked states. The structure is simple and reliable, and the structure is compact, which helps to reduce the overall size of the battery module 10.
[0048] Specifically, the rotating member 422 is located on the side of the driving part 4213 away from the second end 4212. The end face of the driving part 4213 facing the rotating member 422 is provided with a first toothed portion 4215, and the end face of the rotating member 422 facing the driving part 4213 is provided with a second toothed portion 4222. The mating surfaces of the first toothed portion 4215 and the second toothed portion 4222 are inclined surfaces. When the first toothed portion 4215 presses against the second toothed portion 4222 under pressure, the rotating member 422 is driven to rotate around its own axis under the pressure of the mating surfaces, adjusting the position of the first protrusion 4221, thereby achieving the switching between the locked and unlocked positions.
[0049] In some embodiments, such as Figure 8 As shown, within the first receiving cavity 411, the inner wall of the limiting member 41 is provided with a plurality of guide portions 413. The guide portions 413 extend along the first direction X, and a guide groove 414 is formed between two adjacent guide portions 413. A locking portion 412 is formed at the end of the guide portion 413 near the rotating member 422. A second protrusion 4214 is provided on the outer periphery of the driving member 4213, and the second protrusion 4214 is slidably connected within the guide groove 414. In the unlocked state, the first protrusion 4221 is opposite to the guide groove 414 along the first direction X and is adapted to slide along the guide groove 414. The guide groove 414 can guide and limit the rotating member 422 and the driving member 4213 through the first protrusion 4221 and the second protrusion 4214, so that the rotating member 421 and the rotating member 422 can move along the first direction X without rotating.
[0050] For example, both the guide portion 413 and the guide groove 414 can be elongated. For example, the guide portion 413 can be integrally formed on the inner wall of the limiting member 41.
[0051] More specifically, in some embodiments, the first protrusion 4221 includes an intersecting and connected first side surface 42211 and a first inclined surface 42212. The locking portion 412, at one end facing the rotating member 422, has a second side surface 4121 that conforms to the first side surface 42211 and a second inclined surface 4122 that conforms to the first inclined surface 42212. The second inclined surface 4122 is inclined towards the guide groove 414. In this embodiment, the second side surface 4121 can circumferentially limit the rotation of the rotating member 422 through the first side surface 42211, restricting the rotation direction of the rotating member 422; the second inclined surface 4122 can guide the first protrusion 4221 through the first inclined surface 42212, guiding the first protrusion 4221 to the guide groove 414.
[0052] In some embodiments, the elastic member 43 includes a first elastic member 431, which is connected between the battery assembly 3 and the rotating member 422. Specifically, the first elastic member 431 is connected between the third support member 31 and the rotating member 422. Figure 6 As shown, when the interface portion 211 of the charging component 2 is in the hidden state, the first elastic member 431 is in the compressed state. Thus, when the sliding connector 42 is in the unlocked state, the restoring force of the first elastic member 431 pushes the rotating member 422 and the pivot member 421 to slide away from the battery component 3, causing at least a portion of the structure of the charging component 2 to extend outside the first tube 1, and the interface portion 211 switches from the hidden state to the exposed state. Furthermore, when the interface portion 211 is in the exposed state, the first elastic member 431 can be in either the compressed state or the normal state, so that the charging component 2 can remain in the exposed state.
[0053] In some embodiments, the elastic member 43 includes a second elastic member 432, which is located on the side of the drive portion 4213 away from the rotating member 422 and is connected between the drive portion 4213 and the limiting member 41. Figure 6 As shown, when the interface portion 211 of the charging component 2 is in a hidden state, the second elastic member 432 is in a compressed state or a normal state, so that the pivot member 421 can be held in a position close to the rotating member 422, so that the interface portion 211 can be held in a hidden state. Furthermore, when the interface portion 211 is in an exposed state, the second elastic member 432 is in a compressed state.
[0054] Furthermore, in some embodiments, the charging assembly 2 further includes a first support member 22, a pressing member 24, and a flexible connector 23. The first support member 22 is connected to the telescopic assembly 4, specifically to the pivot member 421. The charging component 21 is disposed within the first support member 22, which has a first opening exposing the interface portion 211. Exemplarily, a first receiving groove is formed within the first support member 22, and the charging component 21 is installed within the first receiving groove. The first support member 22 has a first opening communicating with the first receiving groove, and the interface portion 211 is located at the first opening.
[0055] The first support member 22 and the rotating shaft member 421 can be fixedly connected or detachably connected, such as by adhesive, snap-fit, or threaded connection. For example, the first support member 22 and the rotating shaft member 421 are snapped together by a second snap-fit structure 6, which includes a second snap-fit groove and a second snap-fit block. For example, the first support member 22 has a second protruding post protruding towards the rotating shaft member 421, which is sleeved on the second end 4212 of the rotating shaft member 421; the inner wall of the second protruding post has a second snap-fit groove, and the second end 4212 of the rotating shaft member 421 has a second snap-fit block, which engages with the second snap-fit groove. Alternatively, in some embodiments not shown in the figures, the second snap-fit block can be disposed on the first support member 22, and the second snap-fit groove can be disposed on the rotating shaft member 421.
[0056] Furthermore, the pressing member 24 is connected to the end of the first support member 22 away from the telescopic component 4, and the pressing member 24 is located outside the first tube body 1. When the battery module 10 is installed inside the pen barrel 20, the pressing member 24 is located at the end of the pen to form the pen cap of the electronic pen. Exemplarily, the pressing member 24 and the first support member 22 can be connected by means of snap-fit, adhesive, threaded connection, etc.
[0057] Furthermore, the flexible connector 23 is connected between the charging component 21 and the battery assembly 3 to achieve an electrical connection between the charging component 21 and the battery assembly 3. For example, the flexible connector 23 can be a flexible circuit board 33. For example, the flexible connector 23 has a folding portion, which can unfold when the interface portion 211 is exposed to avoid pulling on the flexible connector 23, thus ensuring the reliability of the electrical connection between the charging component 21 and the battery assembly 3.
[0058] In some embodiments, the charging assembly 2 further includes a second tube 25, which is sleeved on the outside of the first support member 22 and connected to the pressing member 24. The second tube 25 has a second opening that exposes the interface portion 211; that is, the second opening corresponds to the aforementioned second opening to allow the interface portion 211 to be exposed. In this embodiment, the second tube 25, combined with the first tube 1, increases the structural strength of the battery module 10.
[0059] For example, the first tube 1 and the second tube 25 can be hardware components; for example, the first tube 1 and the second tube 25 can also be stainless steel components, which have high structural strength.
[0060] In some embodiments, the battery module 10 includes the aforementioned third support member 31, which has a second receiving groove 311. The battery 32 and circuit board 33 are both installed within the second receiving groove 311, and the battery 32 is electrically connected to the circuit board 33. The battery 32 is positioned close to the telescopic component 4, and the circuit board 33 is located on the side of the battery 32 furthest from the telescopic component 4, i.e., close to the pen refill module 30. A through hole is provided on the side of the third support member 31 adjacent to the circuit board 33 to facilitate electrical connection between the circuit board 33 and the pen refill module 30.
[0061] Specifically, the pen refill module 30 includes a second support member 301, a main board member 304, and an electrical connector 305. The second support member 301 forms a second receiving cavity 3013, and the main board member 304 is disposed within the second receiving cavity 3013. A third opening 3016 is provided at one end of the second support member 301 facing the battery module 10, and the third opening 3016 communicates with the second receiving cavity 3013. One end of the electrical connector 305 is located within the second receiving cavity 3013 and is connected to the main board member 304; the other end of the electrical connector 305 extends outward from the third support member 31 through the third opening 3016, and can be electrically connected to the circuit board 33 through a through hole in the third support member 31, thereby realizing the electrical connection between the main board member 304 and the battery module 10.
[0062] For example, electrical connector 305 can be a POGO pin (i.e., a spring pin), which provides high reliability for the electrical connection.
[0063] For example, multiple electrical connectors 305 are provided, and a connecting block 3014 may be provided in the second support member 301. The connecting block 3014 is connected to the second receiving cavity 3013, and the multiple electrical connectors 305 are spaced apart and pass through the connecting block 3014. The connecting block 3014 can define the position of each electrical connector 305 so as to facilitate electrical connection to a predetermined position on the circuit board 33.
[0064] Furthermore, in some embodiments, such as Figure 10As shown, the pen refill module 30 includes a second support member 301 and a telescopic member 302. The second support member 301 passes through the pen barrel 20. The telescopic member 302 is disposed at the end of the second support member 301 facing the battery module 10 and is telescopically oriented along the second direction Y. A first tube 1 is sleeved on the outside of the second support member 301 and has a snap-fit portion 11. The telescopic member 302 is adapted to snap into the snap-fit portion 11 when extended and to disengage from the snap-fit portion 11 when shortened. In this embodiment, the connection and disassembly with the first tube 1 are achieved by the telescopic extension and retraction of the telescopic member 302, improving the convenience of assembling and disassembling the battery module 10.
[0065] Specifically, the telescopic component 302 includes an elastic part 3021 and a ball head 3022 connected together. When the telescopic component 302 extends, the ball head 3022 engages with the locking part 11. When disassembly is required, pulling the battery module 10 causes the ball head 3022 and the locking part 11 to press against each other, compressing the elastic part 3021, shortening the telescopic component 302, and disengaging the ball head 3022 from the locking part 11. In this solution, the battery module 10 can be disassembled simply by pulling, offering high convenience.
[0066] For example, the second support member 301 has a first hole 3015 extending along the second direction Y at one end near the battery module 10, and the telescopic member 302 is installed in the first hole 3015. The diameter of the first hole 3015 is larger than the diameter of the ball head 3022 to facilitate the installation of the telescopic member 302. Further, the cell module also includes a sleeve 303, which is sleeved on the second support member 301, specifically at the end of the second support member 301 near the battery module 10. The sleeve 303 has a second hole 3031 extending along the second direction Y, opposite to the first hole 3015. The ball head 3022 can extend through the first hole 3015 and the second hole 3031 to engage with the snap-fit part 11. The diameter of the second hole 3031 is smaller than the diameter of the ball head 3022 to prevent the telescopic member 302 from detaching from the second support member 301.
[0067] For example, the elastic part 3021 can be a spring, and the ball head 3022 can be a steel ball.
[0068] For example, the snap-fit part 11 can be a snap-fit groove or a snap-fit hole provided on the inner wall of the first tube body 1.
[0069] For example, the second support member 301 includes a first half 3011 and a second half 3012 connected to each other, and a second receiving cavity 3013 is formed between the first half 3011 and the second half 3012. This arrangement facilitates the installation of other components of the pen refill module 30 into the second receiving cavity 3013.
[0070] For example, the second support member 301 and the socket member 303 can both be made of stainless steel or metal to improve the overall structural strength of the electronic pen.
[0071] According to an embodiment of the present invention, another aspect provides a terminal, including a battery module 10 as described in any of the above embodiments; or, including an electronic pen as described in any of the above embodiments. Since the terminal of the present invention includes the battery module 10 or electronic pen of the above embodiments, it has the same technical effects as the battery module 10 or electronic pen of the present invention, and will not be described again here.
[0072] Understandably, the terminal of this utility model can be a mobile phone, tablet, laptop, electronic watch, electronic drawing board, etc., as long as the electronic pen of this utility model can be used to realize the corresponding writing and drawing functions.
[0073] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
