DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0042] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, "plurality" means two or more, and at least one means one, two, or more, unless otherwise clearly and specifically defined.

[0043] Electronic pens are commonly used with tablets, office computers, mobile phones, and other devices, allowing users to write and draw on the device's screen using the pen tip. However, after prolonged use, the pen tip can wear out, affecting its proper function. However, current electronic pens are difficult to quickly replace, making replacement cumbersome. Most commercially available pen tips connect to the pen's internal structure via a threaded connection, which can easily cause rust and slippage, making tip replacement difficult.

[0044] In view of this, an embodiment of the present application provides an electronic pen to overcome at least one of the above-mentioned technical problems.

[0045] See also Figure 1 and Figure 2 In the embodiment of the present application, the electronic pen includes a pen body 10, a support member 20, a pen tip 30 and a fixing member 40.

[0046] The pen body 10 has a accommodating cavity 11 and an opening 12 connected to the accommodating cavity 11. The support member 20 is located in the accommodating cavity 11 and is connected to the pen body 10. The support member 20 has a first placement cavity 21 and a second placement cavity 22 that are connected to each other, and the first placement cavity 21 is connected to the opening 12. The pen tip 30 passes through the opening 12 and the first placement cavity 21 to the second placement cavity 22. It can be understood that the accommodating cavity 11 of the pen body 10 can be installed with structures such as a bracket structure, a pen tip structure, a sensor, a circuit board, and a power module. The opening 12 of the pen body 10 is connected to the accommodating cavity 11, and the pen tip structure can be embedded in the interior of the accommodating cavity 11 through the opening 12 and connected to the structure in the accommodating cavity 11. The support member 20 is a bracket structure in the accommodating cavity 11, which is connected to the inner side of the pen body 10 so that the support member 20 can be stably installed. When installed, the pen tip 30 can be embedded in the first placement cavity 21 and the second placement cavity 22 in the support member 20 through the opening 12, so that the pen tip 30 can only move in the length direction of the pen body 10 and cannot move in the radial direction of the pen body 10, which plays a certain limiting role on the pen tip 30.

[0047] The fixing member 40 is located in the radial direction of the pen tip 30 and is movably connected to the support member 20. The fixing member 40 is made of hardware, has good strength, and has a long service life. The fixing member 40 includes a first protrusion 41 and a second protrusion 42 that protrude toward the pen tip 30. The first protrusion 41 is connected to the second protrusion 42. The first protrusion 41 and the second protrusion 42 both protrude toward the pen tip 30. The first protrusion 41 abuts the pen tip 30, and the second protrusion 42 abuts the pen tip 30. It can be understood that the fixing member 40 needs to be located in the radial direction of the pen tip 30, and can be in the first placement cavity 21 or in the second placement cavity 22, without limitation. The fixing member 40 is connected to the support member 20 to ensure that the fixing member 40 has a relatively stable state to limit the pen tip 30. The fixing member 40 contacts the pen tip 30 via the first protrusion 41, exerting a radial force on the pen tip 30. This increases the friction between the first protrusion 41 and the pen tip 30, providing a certain degree of stability for the pen tip 30 and preventing it from easily falling out of the first and second cavities 21, 22, and opening 12. The second protrusion 42 of the fixing member 40 also exerts a radial force on the pen tip 30, further increasing the frictional resistance of the pen tip 30 in the axial direction, further improving the stability of the pen tip 30. Even if the pen tip 30 is subjected to greater tension, it will not fall out of the first and second cavities 21, 22, and opening 12. If the pen tip 30 becomes damaged after prolonged use and needs to be replaced, it can be directly pulled with a greater force to free it from the restraints of the first and second protrusions 41, 42 and remove it from the interior of the pen body 10. The new pen tip 30 is then replaced, passing through the opening 12 and the first placement cavity 21, and then inserted into the second placement cavity 22. During the insertion process, the first protrusion 41 and the second protrusion 42 squeeze the pen tip 30, thereby again retaining the new pen tip 30 and ensuring the stability of the replaced pen tip 30. This structure facilitates quick replacement of the pen tip 30 if it becomes damaged, is simple and convenient to operate, and the dual retaining effect of the first protrusion 41 and the second protrusion 42 improves the stability of the pen tip 30.

[0048] See also Figure 1 、 Figure 2 and Figure 5In combination with the above embodiments, in some embodiments, the pen tip 30 has a groove 31, which is located in the radial direction of the pen tip 30. At least a portion of the first protrusion 41 is embedded in the groove 31, and / or at least a portion of the second protrusion 42 is embedded in the groove 31. It can be understood that the position of the groove 31 corresponds to the position of the first protrusion 41 and / or the second protrusion 42. The groove 31 can match the shape and size of each protrusion, or it can be an annular structure, arranged around the pen tip 30 in the radial direction of the pen tip 30. The number of grooves 31 can be set as needed, and can be one or more. At least a portion of the first protrusion 41 is embedded in the groove 31, forming a snap-fit ​​structure with the groove 31 and also pressing the pen tip 30, while the second protrusion 42 presses the surface of the pen tip 30. Alternatively, at least a portion of the second protrusion 42 is embedded in the groove 31, forming a snap-fit ​​structure with the groove 31 and also pressing the pen tip 30, while the first protrusion 41 presses the surface of the pen tip 30. Alternatively, at least a portion of the first protrusion 41 and at least a portion of the second protrusion 42 are both embedded in the corresponding groove 31, forming a snap-fit ​​structure with the corresponding groove 31 and pressing the pen tip 30. This arrangement with a snap-fit ​​structure is equivalent to blocking the pen tip 30 with the protrusion, preventing it from easily moving, further improving the stability of the connection between the pen tip 30 and the fixing member 40, and preventing the pen tip 30 from falling off.

[0049] See also Figure 1 、 Figure 2 and Figure 5 In combination with the above embodiments, in some embodiments, the fixing member 40 includes a plurality of fixing protrusions 40a, which are arranged around the pen tip 30, with adjacent fixing protrusions 40a connected. Each fixing protrusion 40a includes a first protrusion 41 and a second protrusion 42. At least a portion of each first protrusion 41 is embedded in the groove 31, and / or at least a portion of each second protrusion 42 is embedded in the groove 31. It will be understood that by arranging the plurality of fixing protrusions 40a around the pen tip 30, the first protrusion 41 on each fixing protrusion 40a also surrounds the pen tip 30 and compresses the outer circumference of the pen tip 30 in the radial direction, thereby further increasing the friction between the fixing member 40 and the pen tip 30. Simultaneously, the second protrusion 42 on each fixing protrusion 40a also surrounds the pen tip 30 and compresses the outer circumference of the pen tip 30 in the radial direction, further increasing the friction between the fixing member 40 and the pen tip 30. At least one of the first and second protrusions 41, 42 on each fixing protrusion 40a is embedded in the corresponding groove 31, forming a snap-fit ​​structure with the groove 31. The multiple first and second protrusions 41, 42 compress the pen tip 30, increasing the friction between the fixing member 40 and the pen tip 30. The multiple snap-fit ​​structures further enhance the stability of the pen tip 30, preventing it from easily falling off.

[0050] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In combination with the above embodiments, in some embodiments, the electronic pen includes a connecting component 50 and a sensing component 60 .

[0051] The connecting member 50 is located within the second receiving cavity 22 and connected to the support member 20. The connecting member 50 has a connecting groove 51 that opens toward the first receiving cavity 21. One end of the pen tip 30 is embedded in the connecting groove 51 along the first direction X. The fixing member 40 is located within the connecting groove 51 and connected to the support member 20 via the connecting member 50. The sensor 60 is at least partially located within the second receiving cavity 22 and connected to the support member 20. The sensor 60 is located on one side of the connecting member 50 along the first direction X and is connected to the connecting member 50. It will be understood that the pen tip 30 extends along the first direction X through the opening 12 and the first receiving cavity 21 into the second receiving cavity 22 and may further extend into the connecting groove 51 of the connecting member 50. Meanwhile, the fixing member 40 may be located within the connecting groove 51 and connected to the connecting member 50, as long as the fixing member 40 is located radially relative to the pen tip 30. The fixing member 40 is connected to the supporting member 20 via the connecting member 50, thereby ensuring a relatively stable state of use and preventing the fixing member 40 from shaking within the connecting slot 51. The portion of the pen tip 30 within the connecting slot 51 can directly abut the connecting member 50, allowing the pen tip 30 to transmit the applied force to the sensor 60 through the connecting member 50. Alternatively, the pen tip 30 can be spaced a certain distance from the connecting member 50, with the pen tip 30 transmitting the applied force to the connecting member 50 via the fixing member 40, and then to the sensor 60 through the connecting member 50. When the electronic pen is writing or drawing, one end of the pen tip 30 contacts the touch screen. The pen tip 30 transmits the force from the touch screen to the connecting member 50, or transmits it to the connecting member 50 through the fixing member 40, so that the connecting member 50 squeezes the sensor 60 along the first direction X. The sensor 60 can sense and detect the force applied to the pen tip 30 along the first direction X, and then transmits the force information to the processor in the form of an electrical signal. After processing by the processor, the electronic pen triggers the corresponding function.

[0052] The first direction X is the direction from the opening 12 to the first placement cavity 21 .

[0053] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In combination with the above embodiments, in some embodiments, the connecting member 50 includes a sleeve portion 52 , an abutting portion 53 and an elastic portion 54 .

[0054] The sleeve portion 52 can be a tubular structure made of metal, offering excellent strength and a long service life. The sleeve portion 52 can be conveniently positioned around the nib 30. At least a portion of the fixing member 40 is located between the nib 30 and the sleeve portion 52, and is connected to the sleeve portion 52 and the nib 30, respectively. The connection between the fixing member 40 and the sleeve portion 52 can improve the stability of the fixing member 40, thereby preventing the fixing member 40 from shaking within the connection slot 51. The connection between the fixing member 40 and the nib 30 can also compress the nib 30 and form a snap connection between the fixing member 40 and the nib 30. The abutment portion 53 is at least partially sleeved on the outer periphery of the sleeve portion 52 and is connected to the sleeve portion 52 by means of threads. The abutment portion 53 and the sleeve portion 52 enclose a connecting groove 51. The abutment portion 53 and the sleeve portion 52 are connected by threads, which facilitates the assembly of the two and also facilitates the installation of the fixing member 40 into the connecting groove 51 enclosed by the abutment portion 53 and the sleeve portion 52. The abutment portion 53 is connected to the fixing member 40, thereby further improving the stability of the fixing member 40 and preventing it from shaking in the connecting groove 51. The pen tip 30 is connected to the sensor 60 via the abutment portion 53. The elastic portion 54 can be a spring structure. The elastic portion 54 is arranged around the sleeve portion 52 and is respectively connected to the support member 20 and the abutment portion 53. The elastic portion 54 presses the abutment portion 53. It is understood that the pen tip 30 can transmit the force applied from the touch screen to the sensor 60 via the abutment 53, allowing the sensor 60 to sense and detect this force. Simultaneously, the elastic portion 54 is in a compressed state, with its ends pressing against the support member 20 and the abutment 53, respectively. The abutment 53, in turn, presses against the sensor 60, eliminating any gaps between them and creating a tight connection between the two. This prevents the connector 50, support member 20, and sensor 60 from shaking or expanding in the first direction X due to gaps when the electronic pen is moved, thus providing a certain degree of structural protection. The compressive force exerted by the elastic portion 54 on the abutment 53 is relatively low, resulting in a relatively low compressive force on the sensor 60. Since this compressive force is always present, this low compressive force can be used as the starting value for the sensor 60's sensing force during the stylus design process. This value can be set to "0," and the force transmitted through the pen tip 30 can be increased from this value. That is to say, the smaller squeezing force will not affect the sensing and detection of the sensor 60 , and the sensor 60 can still accurately detect the force transmitted by the pen tip 30 .

[0055] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In combination with the above embodiments, in some embodiments, the sensing element 60 includes a conducting portion 61 , an extruding portion 62 and a sensing portion 63 .

[0056] The conductive portion 61 is located within the second receiving cavity 22 and abuts one side of the connector 50 along the first direction X. The conductive portion 61 has a mounting groove 611, which is located on the side of the conductive portion 61 facing away from the connector 50. The extrusion portion 62 is located within the mounting groove 611 and connected to the conductive portion 61. The sensing portion 63 is at least partially located within the second receiving cavity 22; a portion of the sensing portion 63 is embedded within the mounting groove 611 and connected to the extrusion portion 62. The side of the sensing portion 63 facing away from the extrusion portion 62 is connected to the support member 20. It is understood that the conductive portion 61 abuts the connector 50, allowing forces acting on the connector 50 to be transmitted to the conductive portion 61. Furthermore, the conductive portion 61 is connected to the sensing portion 63 via the extrusion portion 62. Forces acting on the conductive portion 61 are transmitted to the sensing portion 63 via the extrusion portion 62. The sensing portion 63 senses the transmitted forces, thereby detecting the forces acting on the pen tip 30. The extrusion portion 62 protrudes toward the sensing portion 63, making it easier to connect to the sensing portion 63. Made of high-strength metal, the extrusion portion 62 effectively transmits force to the sensing portion 63 without loss of force and offering a long service life. The sensing portion 63 may be a pressure sensor.

[0057] See also Figure 1 and Figure 2 In combination with the above embodiments, in some embodiments, the conductive portion 61 and the sensing portion 63 are spaced apart, with a gap 64 therebetween. The mounting groove 611 communicates with the second placement cavity 22 via the gap 64. It is understood that to prevent excessive force transmitted by the pen tip 30 from causing the conductive portion 61 to exert excessive instantaneous squeezing force on the sensing portion 63, thereby damaging the sensing portion 63, the gap 64 is provided between the conductive portion 61 and the sensing portion 63. This gap 64 provides a buffer space for the conductive portion 61, preventing the conductive portion 61 from directly exerting excessive force on the sensing portion 63, thereby providing a certain degree of protection for the sensing portion 63.

[0058] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4In combination with the above embodiments, in some embodiments, the support member 20 includes a first support portion 23 and a second support portion 24 that are connected to the pen body 10, providing a certain degree of stability. The first support portion 23 has a first placement cavity 21. At least a portion of the first support portion 23 is embedded within the inner side of the second support portion 24, and together with the second support portion 24, they form a second placement cavity 22. It is understood that the support member 20 is composed of the first and second support portions 23, 24 that are connected. The first placement cavity 21 is formed within the first support portion 23, and the second placement cavity 22 is formed by the first and second support portions 23, 24. In addition to being in communication with the first placement cavity 21, the second placement cavity 22 also communicates with the accommodating cavity 11. Structures within the second placement cavity 22 can extend into the accommodating cavity 11 and communicate with structures within the accommodating cavity 11. Conversely, structures within the accommodating cavity 11 can also extend into the second placement cavity 22 and connect with structures within the second placement cavity 22.

[0059] The second support portion 24 includes a body 241 and a baffle 242, which are connected to each other. The body 241 at least partially surrounds the first support portion 23 and is connected to the first support portion 23 and the pen body 10, respectively. The baffle 242 is located on the side of the sensing portion 63 facing away from the extrusion portion 62 and is connected to the sensing portion 63. It will be understood that the baffle 242 of the second support portion 24 is located on the side of the sensing portion 63 facing away from the extrusion portion 62 and is connected to the sensing portion 63, thereby limiting the position of the sensing portion 63 in the first direction X. When the pen tip 30 transmits force to the conductive portion 61 through the connector 50, the conductive portion 61 compresses the sensing portion 63 through the extrusion portion 62. The baffle 242 limits the sensing portion 63, preventing it from moving when squeezed, thereby dissipating the force and ensuring the accuracy of the sensing portion 63's force sensing and detection.

[0060] See also Figure 2 、 Figure 4 and Figure 6 In combination with the above embodiment, in some embodiments, the second support portion 24 has a guide groove 243. The first support portion 23 includes a support frame 231 and a guide block 232.

[0061] The support frame 231 is at least partially embedded in the inner side of the second support portion 24 and connected to the second support portion 24. The support frame 231 and the second support portion 24 enclose a second placement cavity 22. The guide block 232 is located on the outer periphery of the support frame 231 and is connected to the support frame 231. The guide block 232 is embedded in the guide groove 243. It will be understood that during the process of connecting the support frame 231 and the second support portion 24 to enclose the second placement cavity 22, the guide block 232 connected to the support frame 231 can be embedded in the guide groove 243 of the second support portion 24. When the support frame 231 is embedded in the inner side of the second support portion 24, it can prevent the support frame 231 from rotating, guide the connection between the support frame 231 and the second support portion 24, ensure the alignment of the support frame 231 and the second support portion 24, and also ensure the alignment of the structure within the support frame 231 with the structure within the second support portion 24.
