Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0053] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0054] The following Figures 1 to 18 describes the embodiments of the present utility model.

[0055] According to an embodiment of the present utility model, an electronic pen 1 is provided. The electronic pen 1 includes a pen housing 100, an end cap 200, a pen core assembly 300, and a battery assembly 400. Among them, the electronic pen 1 can be used in conjunction with terminal devices such as tablet computers, laptop computers, and mobile phones.

[0056] The end of the pen housing 100 is provided with a disassembly and assembly opening 110. The end cap 200 is detachably connected to the pen housing 100, and the end cap 200 seals the disassembly and assembly opening 110. The pen core assembly 300 is disposed in the pen housing 100 and is provided with a first electrical connection position 301. The battery assembly 400 is movably disposed in the pen housing 100 and is located between the pen core assembly 300 and the end cap 200. The battery assembly 400 is provided with a second electrical connection position 401, and the first electrical connection position 301 and the second electrical connection position 401 are separably connected.

[0057] For example, the first electrical connection position 301 of the pen core assembly 300 and the second electrical connection position 401 of the battery assembly 400 can be connected by connection methods such as abutting and plugging that are easy to separate.

[0058] When the end cap 200 is connected to the pen shell 100, the end cap 200 closes the disassembly and assembly opening 110, which can not only prevent sundries such as dust from entering the pen shell 100 through the disassembly and assembly opening 110, ensure the cleanliness of the electronic pen 1, but also prevent the battery assembly 400 from detaching from the pen shell 100 through the disassembly and assembly opening 110, ensuring the reliability of the structure of the electronic pen 1;

[0059] When the end cap 200 is separated from the pen shell 100, the disassembly and assembly opening 110 is opened. Since the battery assembly 400 is located between the pen core assembly 300 and the end cap 200, and the battery assembly 400 is movable relative to the pen shell 100, the battery assembly 400 can move in the direction close to the disassembly and assembly opening 110, the first electrical connection position 301 and the second electrical connection position 401 are separated, and the battery assembly 400 in the pen shell 100 can be detached from the pen shell 100 through the disassembly and assembly opening 110, and operations such as charging and detecting the battery assembly 400 can be performed. Or another battery assembly 400 can also be installed into the pen shell 100 through the disassembly and assembly opening 110, the first electrical connection position 301 and the second electrical connection position 401 are connected, and the battery assembly 400 supplies power to the pen core assembly 300, realizing the replacement of the battery assembly 400.

[0060] In this way, the battery assembly 400 can be detached from the electronic pen 1, and when disassembling, only the end cap 200 needs to be opened, and the disassembly of the battery assembly 400 is convenient. By replacing the battery assembly 400, problems such as shortened battery life or reduced power supply capacity after long-term use of the battery assembly 400 affecting the service life of the electronic pen 1 can be avoided, and the service life of the electronic pen 1 can be extended. Moreover, when the electronic pen 1 is scrapped, the battery assembly 400 can be detached separately, realizing the recycling treatment of the battery assembly 400, reducing the environmental pollution of the electronic pen 1, and improving the environmental protection effect.

[0061] As Figures 2 - 6 shown, in the technical solution of this embodiment, the pen core assembly 300 includes a bracket 310, a first circuit board 320 and a spring pin 330.

[0062] The bracket 310 is installed on the pen shell 100 and includes a connecting wall 312. The first circuit board 320 is installed on the bracket 310. The connecting wall 312 is located between the first circuit board 320 and the battery assembly 400 in the axial direction of the electronic pen 1. The spring pin 330 is inserted into the connecting wall 312 and is connected to the first circuit board 320 through a first wire 340. The first electrical connection position 301 is formed at one end of the spring pin 330 facing the battery assembly 400.

[0063] For example, the first circuit board 320 can be the main control board of the electronic pen 1, which is used to control the electronic pen 1 to realize various functions, such as controlling the electronic pen 1 to realize the writing function and wiping function on the terminal. Moreover, the first wire 340 and the first circuit board 320 can be formed into an integral structure, and the first wire 340 and the spring pin 330 are welded.

[0064] Specifically, as Figure 7 shown, the bracket 310 further includes a main body 311 and a limiting wall 313. The main body 311 at least partially surrounds the first circuit board 320. The main body 311 extends along the axial direction of the electronic pen 1. The limiting wall 313 is connected to one end of the main body 311 away from the disassembly and assembly port 110. The limiting wall 313 and the connecting wall 312 are located on opposite sides of the first circuit board 320 in the axial direction of the electronic pen 1. Through the cooperation of the connecting wall 312 and the limiting wall 313, the relative positions of the first circuit board 320 and the bracket 310 in the axial direction of the electronic pen 1 can be defined.

[0065] The connecting wall 312 is provided with a mounting hole 3121. The mounting hole 3121 includes a first hole section 3122 and a second hole section 3123. The first hole section 3122 and the second hole section 3123 are communicated. The first hole section 3122 is closer to the battery assembly 400 than the second hole section 3123. The diameter of the first hole section 3122 is larger than the diameter of the second hole section 3123.

[0066] As Figure 4 shown, the spring pin 330 includes a pin housing 331, a spring 332 and a pin head 333. The pin housing 331 includes a thick section 3311 and a thin section 3312. The thick section 3311 is disposed in the first hole section 3122 and extends beyond one side surface of the connecting wall 312 facing the battery assembly 400. The thin section 3312 is disposed in the second hole section 3123 and extends beyond one side surface of the connecting wall 312 facing away from the battery assembly 400. The thin section 3312 is connected to the first wire 340. The spring 332 and the pin head 333 are disposed in the thick section 3311. The spring 332 is located between the pin head 333 and the pin housing 331 in the axial direction of the electronic pen 1. The pin head 333 extends out of the pin housing 331 and abuts against the battery assembly 400. The spring 332 undergoes elastic deformation. The spring 332 exerts an elastic force on the pin head 333. This elastic force drives the pin head 333 to move in the direction of the battery assembly 400 to ensure the reliability of the electrical connection between the pin head 333 and the battery assembly 400. Among them, the spring pin 330 can be a POGOpin.

[0067] Among them, the inner peripheral surface of the pen shell 100 has a first positioning area 130, and the outer peripheral surface of the bracket 310 has a second positioning area 315. The first positioning area 130 and the second positioning area 315 can be mutually cooperating planes to fix the relative positions between the pen shell 100 and the bracket 310.

[0068] By providing the bracket 310, the relative positions between the first circuit board 320 and the pogo pin 330 can be fixed, ensuring the reliability of the electrical connection between the first circuit board 320 and the pogo pin 330. By providing the first circuit board 320, the normal operation of the electronic pen 1 can be controlled. By providing the pogo pin 330, taking advantage of the characteristic that the pogo pin 330 can undergo elastic deformation, the reliability of the electrical connection between the battery assembly 400 and the refill assembly 300 can be ensured.

[0069] As Figures 3 - 5 and Figure 7 shown, in the technical solution of this embodiment, a boss 314 is provided on the side of the connecting wall 312 facing the battery assembly 400. A first positioning groove 3141 is provided on the outer peripheral surface of the boss 314. One end of the battery assembly 400 facing the refill assembly 300 is provided with a groove 4121. The boss 314 is inserted into the groove 4121, and a second positioning groove 4125 is provided on the inner peripheral surface of the groove 4121.

[0070] The refill assembly 300 further includes an elastic connecting member 350. The elastic connecting member 350 includes an elastic body 352 and a positioning protrusion 351. The elastic body 352 is installed in the first positioning groove 3141, and the positioning protrusion 351 is inserted into the second positioning groove 4125.

[0071] Among them, the elastic connecting member 350 can undergo elastic deformation. The elastic connecting member 350 can be made of silicone material or rubber material. Moreover, the elastic connecting member 350 can be adhesively bonded into the first positioning groove 3141 by glue to prevent the elastic connecting member 350 from separating from the boss 314 under force.

[0072] By providing the cooperation of the boss 314 and the groove 4121, pre-positioning can be performed between the battery assembly 400 and the refill assembly 300 during the assembly of the battery assembly 400 and the refill assembly 300, improving the convenience of assembly. In addition, by providing the elastic connecting member 350, the gap between the outer peripheral surface of the boss 314 and the inner peripheral surface of the groove 4121 can be filled. The elastic connecting member 350 can undergo elastic deformation to fix the relative positions between the boss 314 and the groove 4121, preventing relative shaking between the boss 314 and the groove 4121 from generating abnormal noises, and thus the relative positions between the battery assembly 400 and the refill assembly 300 are stable.

[0073] As Figure 3 shown, in the technical solution of this embodiment, first positioning grooves 3141 are provided on the opposite sides of the boss 314 in the radial direction of the electronic pen 1. An elastic connecting member 350 is provided in each first positioning groove 3141. Second positioning grooves 4125 are provided on the opposite sides of the inner peripheral surface of the groove 4121 in the radial direction of the electronic pen 1. The two elastic connecting members 350 are inserted into the two second positioning grooves 4125 in a one-to-one correspondence.

[0074] In this way, when the boss 314 is inserted into the groove 4121 and pulled out from the groove 4121, both elastic connectors 350 can undergo elastic deformation, making the connection and separation between the boss 314 and the groove 4121 more convenient, and the connection and separation between the battery assembly 400 and the refill assembly 300 more convenient. In addition, the two elastic connectors 350 can fix the relative positions between the battery assembly 400 and the refill assembly 300 from the opposite sides in the radial direction of the electronic pen 1, further reducing the probability of relative shaking between the battery assembly 400 and the refill assembly 300, more effectively generating abnormal noises, and improving the structural stability and use comfort of the electronic pen 1.

[0075] As Figure 8 and Figure 9 shown, in the technical solution of this embodiment, the positioning protrusion 351 is provided with a first guiding surface 3511 and a second guiding surface 3512. The first guiding surface 3511 is located on the side of the positioning protrusion 351 facing the disassembly and assembly opening 110, and the height of the first guiding surface 3511 gradually increases in the direction away from the disassembly and assembly opening 110, that is, the distance between the first guiding surface 3511 and the outer peripheral surface of the boss 314 gradually increases in the direction away from the disassembly and assembly opening 110. The second guiding surface 3512 is located on the side of the positioning protrusion 351 facing away from the disassembly and assembly opening 110, and the height of the second guiding surface 3512 gradually decreases in the direction away from the disassembly and assembly opening 110, that is, the distance between the second guiding surface 3512 and the outer peripheral surface of the boss 314 gradually decreases in the direction away from the disassembly and assembly opening 110.

[0076] For example, the positioning protrusion 351 is further provided with a flat surface 3513, and the height of the flat surface 3513 remains unchanged, that is, the distance between the flat surface 3513 and the outer peripheral surface of the boss 314 remains unchanged. The flat surface 3513 is axially connected to the first guiding surface 3511 and the second guiding surface 3512 in the electronic pen 1, that is, the first guiding surface 3511, the flat surface 3513, and the second guiding surface 3512 are arranged in sequence along the axial direction of the electronic pen 1, and the positioning protrusion 351 generally forms a table-like structure. Moreover, the shape of the second positioning groove 4125 is adapted to the shape of the positioning protrusion 351 to prevent the positioning protrusion 351 from shaking in the second positioning groove 4125.

[0077] By providing the first guiding surface 3511, when the boss 314 is inserted into the groove 4121, the first guiding surface 3511 cooperates with the inner peripheral surface of the groove 4121, making it more convenient for the boss 314 to be inserted into the groove 4121 and increasing the connection convenience. By providing the second guiding surface 3512, when the boss 314 is pulled out from the groove 4121, the second guiding surface 3512 cooperates with the groove wall of the second positioning groove 4125, making it more convenient for the positioning protrusion 351 to move out of the second positioning groove 4125. Therefore, it is more convenient for the boss 314 to be pulled out from the groove 4121, increasing the disassembly convenience.

[0078] As Figures 10 - 13 shown, in the technical solution of this embodiment, the battery assembly 400 includes a mounting case 410, a battery 420, and a second circuit board 430.

[0079] The mounting case 410 is provided with a battery compartment 413. The battery 420 is installed in the battery compartment 413. The second circuit board 430 is disposed in the battery compartment 413 and is located between the battery 420 and the refill assembly 300. The battery 420 is connected to the circuit board through a second wire 440. A second electrical connection position 401 is formed on the side of the second circuit board 430 facing the refill assembly 300 and is electrically connected to the second wire 440.

[0080] For example, the second wire 440 and the battery 420 can be integrally formed, and the second wire 440 and the second circuit board 430 can be welded. Moreover, a through hole 414 can be provided at one end of the mounting case 410 facing the refill assembly 300. The spring pin 330 abuts against the second electrical connection position 401 of the second circuit board 430 through the through hole 414. The spring pin 330 can elastically deform to ensure the reliability of the electrical connection between the first electrical connection position 301 and the second electrical connection position 401.

[0081] In addition, a third positioning area 415 is provided on the outer peripheral surface of the mounting case 410. The third positioning area 415 cooperates with the first positioning area 130 of the pen case 100. Among them, the third positioning area 415 can be a plane to prevent relative rotation between the battery assembly 400 and the pen case 100 and ensure the positioning accuracy between the battery assembly 400 and the pen case 100.

[0082] By providing the mounting case 410, on the one hand, it can fix the relative positions between the battery 420 and the second circuit board 430, and the relative positions between the battery 420 and the second circuit board 430 will not change during the disassembly and assembly process, ensuring the reliability of the electrical connection between the second circuit board 430 and the battery 420. On the other hand, a positioning structure can be provided on the mounting case 410 to ensure the positioning accuracy between the second circuit board 430 and the refill assembly 300, so that the second circuit board 430 is electrically connected to the refill assembly 300. There is no need to process a positioning structure on the battery 420, and the battery 420 does not need to contact the structures outside the mounting case 410, reducing the probability of damage to the battery 420.

[0083] As Figures 10 - 13 shown, in the technical solution of this embodiment, the mounting case 410 includes a case body 411 and a case cover 412. The case cover 412 is detachably connected to the case body 411 and jointly defines the battery compartment 413. The case cover 412 is located between the case body 411 and the refill assembly 300. The second circuit board 430 is connected to the case cover 412.

[0084] For example, on the side of the shell cover 412 facing the pen shell 100, there is a receiving groove 4122. The receiving groove 4122 and the groove 4121 are connected through a through hole 414. The second circuit board 430 is installed in the receiving groove 4122. A first protruding portion 431 is provided on the outer peripheral surface of the second circuit board 430. A first through hole 4123 is provided on the groove wall of the receiving groove 4122. The first protruding portion 431 is inserted into the first through hole 4123. The first protruding portion 431 is arranged on opposite sides of the second circuit board 430 in the radial direction of the electronic pen 1.

[0085] Moreover, a second protruding portion 4124 is provided on the outer peripheral surface of the receiving groove 4122. A second through hole 4111 is provided on the peripheral wall of the shell 411. The second protruding portion 4124 is inserted into the second through hole 4111. The second protruding portion 4124 is arranged on opposite sides of the receiving groove 4122 in the radial direction of the electronic pen 1. Wherein, the connecting line between the two second protruding portions 4124 and the connecting line between the two first through holes 4123 are perpendicularly arranged, reducing the probability of interference between the shell 411 and the second circuit board 430.

[0086] By detachably connecting the shell cover 412 and the shell 411, it is more convenient to place the second circuit board 430 and the battery 420 in the battery compartment 413. Moreover, the second circuit board 430 and the battery 420 can be taken out from the battery compartment 413, facilitating the recycling of the second circuit board 430 and the battery 420, improving the utilization rate of electronic devices, avoiding environmental pollution, and improving the cleaning effect. In addition, when replacing the battery assembly 400, the mounting shell 410 does not need to be scrapped and can be recycled, reducing the replacement cost.

[0087] Such as Figure 2 、 Figure 3 、 Figure 14 and Figure 16 As shown in

[0088] For example, the plug-in ring portion 210 includes a plurality of plug-in pieces 211. The plurality of plug-in pieces 211 are arranged at intervals along the circumferential direction of the electronic pen 1. A fixing protrusion 214 is provided at the end of each plug-in piece 211. A plurality of fixing grooves 140 are provided on the inner wall of the pen shell 100. The plurality of fixing protrusions 214 are inserted into the plurality of fixing grooves 140 in a one-to-one correspondence. Since the plurality of plug-in pieces 211 are arranged at intervals, each plug-in piece 211 is convenient to deform, and the cooperation between the fixing groove 140 and the fixing protrusion 214 is more convenient.

[0089] Among them, the number of the positioning pieces 402 can be the same as that of the insertion pieces 211, and the multiple positioning pieces 402 and the multiple insertion pieces 211 are arranged in one-to-one correspondence, or the number of the positioning pieces 402 can be less than that of the insertion pieces 211, and a part of the multiple insertion pieces 211 is correspondingly arranged with the multiple positioning pieces 402.

[0090] In addition, Figure 1 and Figure 15 As shown, an operation groove 120 can be provided on the outer peripheral surface of the pen shell 100. The operation groove 120 is located at the edge of the pen shell 100. There can be multiple operation grooves 120, and the multiple operation grooves 120 are arranged at intervals along the circumferential direction of the electronic pen 1. A user can insert a hand into the operation groove 120 to contact the end cap 200, and apply a pulling force to the end cap 200 along the axial direction of the electronic pen 1 to separate the end cap 200 from the pen shell 100, facilitating the disassembly and assembly between the end cap 200 and the pen shell 100.

[0091] By providing the multiple positioning pieces 402, the positioning pieces 402 and the pen shell 100 are located on opposite sides of the insertion ring portion 210 in the radial direction of the electronic pen 1. When an external force causes the end cap 200 to move relative to the pen shell 100 (for example, when the electronic pen 1 drops to the ground), the positioning pieces 402 can fix the relative positions of the end cap 200 and the pen shell 100, prevent the end cap 200 and the pen shell 100 from being accidentally separated, and further avoid the accidental detachment of the battery assembly 400 from the pen shell 100, ensuring the reliability of the structure of the electronic pen 1.

[0092] As Figure 14 shown, in the technical solution of this embodiment, a clamping piece 403 is provided at one end of the battery assembly 400 facing the end cap 200. The clamping piece 403 extends beyond one end of the pen shell 100 facing the end cap 200, and the clamping piece 403 is located at the center of the battery assembly 400.

[0093] Specifically, the clamping piece 403 extends beyond one end of the positioning piece 402 facing the end cap 200, the positioning piece 402 does not extend beyond one end of the pen shell 100 facing the end cap 200, and the positioning piece 402 is located inside the pen shell 100.

[0094] By providing the clamping piece 403, when the end cap 200 is separated from and installed on the pen shell 100, a user can directly pinch the clamping piece 403 or use a machine to clamp the clamping piece 403 to pull out the battery assembly 400 from the pen shell 100. Moreover, the clamping piece 403 is located at the center of the battery assembly 400, and the battery assembly 400 is evenly stressed, avoiding the relative deflection of the battery assembly 400 with respect to the pen shell 100 and the increase in friction force during the pulling process, and increasing the convenience of pulling out the battery assembly 400 from the pen shell 100.

[0095] As Figure 17 and Figure 18As shown, in the technical solution of this embodiment, the electronic pen 1 further includes a buffer member 500, and the buffer member 500 is axially clamped between the end cap 200 and the battery assembly 400 of the electronic pen 1. Among them, the buffer member 500 can undergo elastic deformation, and the buffer member 500 can be foam or the like.

[0096] For example, the buffer member 500 is sleeved on the clamping piece 403, the buffer member 500 is provided with a plurality of avoidance notches 510, and a plurality of positioning pieces 402 are respectively arranged in the plurality of avoidance notches 510. Among them, the plurality of insertion pieces 211 can include a plurality of wide insertion pieces 212 and a plurality of narrow insertion pieces 213, and the wide insertion pieces 212 and the narrow insertion pieces 213 are alternately arranged along the circumferential direction of the electronic pen 1. The plurality of narrow insertion pieces 213 are arranged corresponding to the plurality of positioning pieces 402 one by one. The buffer member 500 is axially clamped between the wide insertion piece 212 and the battery assembly 400. In this way, while the relative position of the end cap 200 and the pen case 100 is defined by the positioning piece 402, the contact area between the buffer member 500 and the end cap 200 is large.

[0097] By providing the buffer member 500, the buffer member 500 can fill the gap between the end cap 200 and the battery assembly 400 axially on the electronic pen 1, define the relative position of the end cap 200 and the battery assembly 400 axially on the electronic pen 1, prevent abnormal noise generated by the shaking of the battery assembly 400, and prevent abnormal noise generated between the end cap 200 and the pen case 100 due to assembly tolerance, thereby improving the structural stability and use comfort of the electronic pen 1.
