[0043] As shown in Figures 1 to 12 The electronic pen comprises: a driving assembly 10, a driven assembly 20, and an elastic pen barrel 30.

[0044] The elastic pen barrel 30 is sleeved on the driven assembly 20, and the driven assembly 20 is in contact with the inner wall of the elastic pen barrel 30. The driving assembly 10 is towards the driven assembly 20, and the driving assembly 10 is movable relative to the driven assembly 20. The elastic sleeve is fixed with a fixed assembly 40, and the fixed assembly 40 is in contact with the driven assembly 20 in the axial direction of the elastic pen barrel 30. In the case that the driving assembly 10 moves in the first direction X, the driving assembly 10 drives the driven assembly 20 to move in the radial direction of the elastic pen barrel 30, so as to increase the diameter of the elastic pen barrel 30. In the case that the driving assembly 10 moves in the second direction Y, the driven assembly 20 resets, so as to restore the diameter of the elastic pen barrel 30 to the initial size. The first direction X is opposite to the second direction Y.

[0045] In the embodiment of the present application, since the elastic pen barrel 30 is sleeved on the driven assembly 20, and the driven assembly 20 is in contact with the inner wall of the elastic pen barrel 30, once the driven assembly 20 moves in the radial direction of the elastic pen barrel 30, the diameter of the elastic pen barrel 30 can be changed, so that the size of the pen body of the electronic pen can be changed. Since the driving assembly 10 is towards the driven assembly 20, and the driving assembly 10 is movable relative to the driven assembly 20, the elastic sleeve is fixed with the fixing assembly 40, and the fixing assembly 40 is in abutment with the driven assembly 20 in the axial direction of the elastic pen barrel 30, therefore, when it is needed to adjust the size of the pen body of the electronic pen, the driving assembly 10 can be moved in the first direction X, and the driving assembly 10 can drive the driven assembly 20 to move, but the driven assembly 20 is blocked by the fixing assembly 40, so that the driven assembly 20 is difficult to move in the axial direction of the elastic pen barrel 30, thereby the driving assembly 10 drives the driven assembly 20 to move in the radial direction of the elastic pen barrel 30, and the driven assembly 20 can press the inner wall of the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 increases, thereby the size of the pen body increases, to meet the needs of the people who need a larger pen body size; then once it is not needed to increase the size of the pen body, the driving assembly 10 can be moved in the second direction Y, so that the elastic pen barrel 30 can rely on its elastic force to reset the driven assembly 20, and then the diameter of the elastic pen barrel 30 returns to the initial size, so that the electronic pen can meet the needs of the people whose pen body size is normal. That is, in the embodiment of the present application, by arranging the elastic pen barrel 30, the fixing assembly 40, the driven assembly 20 and the driving assembly 10, the driving assembly 10 can be driven to move in the axial direction of the elastic pen barrel 30 by applying force to the driving assembly 10, to drive the driven assembly 20 to move in the radial direction of the elastic pen barrel 30, and the driven assembly 20 applies force to the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 increases, thereby the size of the pen body of the electronic pen increases, when it is not needed to increase the size of the pen body of the electronic pen, the driven assembly 20 can be reset, so that the size of the pen body of the electronic pen returns to normal, that is, in the embodiment of the present application, the size of the pen body of the electronic pen is adjustable, so that the electronic pen can meet the needs of different people.

[0046] It should be noted that in the embodiment of the present application, the material of the elastic pen barrel 30 can be rubber, so that the elastic pen barrel 30 can be deformed, of course, the material of the elastic pen barrel 30 can also be other deformable materials, for example, the material of the elastic pen barrel 30 is silica gel. The specific material of the elastic pen barrel 30 is not limited in the embodiment of the present application.

[0047] In addition, in the embodiment of the present application, the first direction X and the second direction Y can both be parallel to the axial direction of the elastic pen barrel 30, so as to make the driving assembly 10 move along the axial direction of the elastic pen barrel 30, the driving assembly 10 makes the driven assembly 20 move along the radial direction of the elastic pen barrel 30, and the size of the pen body of the electronic pen is adjusted, so that in actual application, the user can conveniently apply force along the axial direction of the elastic pen barrel 30, thereby facilitating the user to adjust the size of the pen body. Of course, the first direction X and the second direction Y can also both intersect the axial direction of the elastic pen barrel 30, at this time, only the direction after the first direction X is decomposed has a direction extending along the axial direction of the elastic pen barrel 30, and the direction after the second direction Y is decomposed has a direction extending along the axial direction of the elastic pen barrel 30, so that when the driving assembly 20 moves along the first direction, the driving assembly 20 can still apply force to the driven assembly 40, so that the inner wall of the elastic pen barrel 30 is stressed and the diameter of the elastic pen barrel 30 increases, and when the driving assembly 20 moves along the second direction, the driven assembly 40 can also reset. In addition, in some embodiments, the first direction X and the second direction Y can also extend along the radial direction of the elastic pen barrel 30, at this time, it is equivalent to that along the first direction X, the driving assembly 40 applies force to the driven assembly 20, the driven assembly 20 extrudes the inner wall of the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 increases, and along the second direction Y, the driving assembly 40 moves, so that the driven assembly 40 resets, and the diameter of the elastic pen barrel 30 returns to the initial size.

[0048] In addition, in the embodiment of the present application, the elastic pen barrel 30 is used to be held, that is, when the user uses the electronic pen, the user holds the elastic pen barrel 30 of the electronic pen, and by adjusting the diameter of the elastic pen barrel 30, it is equivalent to adjusting the size of the holding position of the user holding the electronic pen, so as to meet the needs of different groups of people. That is, for the group of people who need a larger size of the holding position, the size of the elastic pen barrel 30 can be increased, and for the group of people who need a smaller size of the holding position, the size of the elastic pen barrel 30 can remain the original size.

[0049] In addition, in the embodiment of the present application, the driving assembly 10 and the driven assembly 20 can be in contact, at this time, once the driving assembly 10 is stressed, the driving assembly 10 can directly apply force to the driven assembly 20, so that the driven assembly 20 extrudes the inner wall of the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 increases; of course, the driving assembly 10 and the driven assembly 20 can also have a gap, at this time, once the driving assembly 10 is stressed, the driving assembly 10 moves and then contacts the driven assembly 20, the driving assembly 10 applies force to the driven assembly 20, so that the driven assembly 20 extrudes the inner wall of the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 increases; after the driving assembly 10 resets, the driving assembly 10 and the driven assembly 20 again have a gap.

[0050] In some embodiments, as shown in FIG. 1, the driving assembly 10 is provided with a first inclined surface 101, and the driven assembly 20 is provided with a second inclined surface 201. The first inclined surface 101 is matched with the second inclined surface 201. When the driving assembly 10 moves in the first direction X, the first inclined surface 101 is separated from the second inclined surface 201, and at least part of the driving assembly 10 moves to one side of the driven assembly 20 in the radial direction of the elastic barrel 30, so that the driven assembly 20 moves in the radial direction of the elastic barrel 30. When the driving assembly 10 moves in the second direction Y, the first inclined surface 101 is matched with the second inclined surface 201. Figure 1 、 Figure 3 、 Figure 4 、 Figure 11 and Figure 12 In some embodiments, as shown in FIG. 1, the driving assembly 10 is provided with a first inclined surface 101, and the driven assembly 20 is provided with a second inclined surface 201. The first inclined surface 101 is matched with the second inclined surface 201. When the driving assembly 10 moves in the first direction X, the first inclined surface 101 is separated from the second inclined surface 201, and at least part of the driving assembly 10 moves to one side of the driven assembly 20 in the radial direction of the elastic barrel 30, so that the driven assembly 20 moves in the radial direction of the elastic barrel 30. When the driving assembly 10 moves in the second direction Y, the first inclined surface 101 is matched with the second inclined surface 201.

[0051] When it is necessary to adjust the size of the pen body of the electronic pen, the driving assembly 10 can be moved along the first direction X, at this time, the first inclined surface 101 of the driving assembly 10 can slide relative to the second inclined surface 201 of the driven assembly 20, and the cooperation between the first inclined surface 101 and the second inclined surface 201 can ensure that the first inclined surface 101 of the driving assembly 10 is separated from the second inclined surface 201 after the driving assembly 10 slides relative to the driven assembly 20, so that at least part of the driving assembly 10 moves to one side of the driven assembly 20 in the radial direction of the elastic barrel 30, i.e., at least part of the driving assembly 10 moves to the side of the driven assembly 20 away from the elastic barrel 30, and in the process of moving of the driving assembly 10, the fixed assembly 40 blocks the movement of the driven assembly 20 along the axial direction of the elastic barrel 30, so that the driven assembly 20 is driven by the driving assembly 10 to move along the radial direction of the elastic assembly, and the driven assembly 20 will press the inner wall of the elastic barrel 30, which is equivalent to that the inside of the elastic barrel 30 exerts a force on the elastic barrel 30, so that the elastic barrel 30 is equivalent to be expanded, the diameter of the elastic barrel 30 increases, and the size of the pen body of the electronic pen increases. In addition, at least part of the driving assembly 10 moves to one side of the driven assembly 20 in the radial direction of the elastic barrel 30, and at least part of the driving assembly 10 is equivalent to support the driven assembly 20 to a certain extent, so as to support the inner wall of the elastic barrel 30 in the radial direction of the elastic barrel 30, avoiding the elastic barrel 30 to reset due to its elasticity, i.e., ensuring that the size of the elastic barrel 30 remains unchanged after the size of the elastic barrel 30 is increased by the driven assembly 20. When it is not necessary to adjust the size of the pen body of the electronic pen, or when it is necessary to restore the size of the pen body of the electronic pen, the driving assembly 10 can be moved along the second direction Y, at this time, the first inclined surface 101 can be moved to the second inclined surface 201 again, cooperate with the second inclined surface 201, and the elastic barrel 30 is no longer supported due to the movement of the driving assembly 10, so that the elastic barrel 30 restores to the initial state by relying on its elasticity, i.e., the diameter of the elastic barrel 30 restores to the initial size. That is, by setting the first inclined surface 101 and the second inclined surface 201, the driving assembly 10 can be moved relative to the driven assembly 20, and the size of the pen body of the electronic pen can be adjusted.

[0052] In addition, in some embodiments, as shown in Figure 3 and Figure 10 The driven assembly 20 can include at least one driven block 21, each driven block 21 is provided with a second inclined surface 201, and each driven block 21 is in contact with the inner wall of the elastic barrel 30, and at least part of the driven block 21 abuts against the fixed assembly 40.

[0053] By such arrangement, when the size of the pen body of the electronic pen needs to be adjusted, the active assembly 10 can be moved along the first direction X, so that the first inclined surface 101 on the active assembly 10 moves relative to the second inclined surface 201 on the driven block 21, the driven block 21 is blocked by the fixed assembly 40, so that the driven block 21 is difficult to move along the axial direction of the elastic barrel 30, and then at least part of the active assembly 10 moves to the side away from the inner wall of the elastic barrel 30, the active assembly 10 moves the driven block 21 along the radial direction of the inner wall of the elastic barrel 30, so that the driven block 21 exerts force on the inner wall of the elastic barrel 30, so that the diameter of the elastic barrel 30 increases. In addition, the size of the driven block 21 is small, which can facilitate movement, so that the active assembly 10 drives the driven block 21 to move after moving, so that the diameter of the elastic barrel 30 increases, and the size of the pen body of the electronic pen is adjusted.

[0054] It should be noted that the number of driven blocks 21 can be set according to actual needs. For example, the number of driven blocks 21 is 12, and every 6 driven blocks 21 in the 12 driven blocks 21 is a group, so that the two groups of driven blocks 21 are distributed along the axial direction of the elastic barrel 30, and each group of driven blocks 21 is distributed along the circumferential direction of the elastic barrel 30. Once the active assembly 10 moves along the first direction X, the 12 driven blocks 21 can move along the radial direction of the elastic barrel 30, so that the 12 driven blocks 21 simultaneously exert force on the inner wall of the elastic barrel 30, the diameter of the elastic barrel 30 can be quickly increased, and each group of driven blocks 21 can increase the diameter of the elastic barrel 30 along the radial direction thereof, facilitating the user to hold the elastic barrel 30 subsequently. For another example, the number of driven blocks 21 is 14. The specific number of driven blocks 21 is not limited in the embodiment of the application.

[0055] In addition, in the embodiment of the application, when the number of driven blocks 21 is multiple, only part of the driven blocks 21 in the multiple driven blocks 21 can abut against the fixed assembly 40, of course, each driven block 21 can also abut against the fixed assembly 40. When the multiple driven blocks 21 are distributed along the axial direction of the elastic barrel 30, only part of the driven blocks 21 can abut against the fixed assembly 40 along the axial direction of the elastic barrel 30, which can save the fixed assembly 40 and thus save the cost. Of course, each fixed block can also abut against the fixed assembly 40. The embodiment of the application does not limit this.

[0056] Furthermore, in this embodiment, there are multiple driven blocks 21, which are divided into at least two groups of driven blocks 21. These groups are spaced apart along the axial direction of the elastic pen cylinder 30, with each group comprising at least two driven blocks 21. Each group of driven blocks 21 is also spaced apart along the circumferential direction of the elastic pen cylinder 30. With this arrangement, once the active component 10 moves along the first direction X, each group of driven blocks 21 moves radially along the elastic pen cylinder 30, thereby applying force to the inner wall of the elastic pen cylinder 30. Since each group of driven blocks 21 is spaced apart along the circumferential direction of the elastic pen cylinder 30, when each group of driven blocks 21 applies force to the inner wall of the elastic pen cylinder 30, the inner wall of the elastic pen cylinder 30 is effectively subjected to force along its circumferential direction. This allows the elastic pen cylinder 30 to be stretched more evenly, increasing its inner diameter. That is, by setting each group of driven blocks 21 to be spaced apart along the circumferential direction of the elastic pen holder 30, the inner diameter of the elastic pen holder 30 can be increased more uniformly.

[0057] Additionally, in some embodiments, such as Figure 3 and Figure 7 As shown, the driven component 20 may further include a driven plate 22, which extends along the axial direction of the elastic pen holder 30 and contacts the inner wall of the elastic pen holder 30. Along the axial direction of the elastic pen holder 30, the driven plate 22 has at least two mounting grooves 221, each mounting groove 221 is fixed with a driven block 21, and the second inclined surface 201 is located outside the mounting groove 221. At least part of the fixing component 40 is located in the mounting groove 221 and abuts against the driven block 21.

[0058] Since the driven plate 22 extends along the axial direction of the elastic pen cylinder 30 and contacts the inner wall of the elastic pen cylinder 30, once the driven plate 22 moves along the radial direction of the elastic pen cylinder 30, the driven plate 22 can make the elastic pen cylinder 30 be subjected to more force in the axial direction of the elastic pen cylinder 30, which makes it easier for the elastic pen cylinder 30 to be stretched open and increase the diameter of the elastic pen cylinder 30. In addition, each mounting slot 221 is fixed with a driven block 21, and the second inclined surface 201 is located outside the mounting slot 221. Thus, once the size of the electronic pen body needs to be adjusted, the active component 10 moves along the first direction X, and the active component 10 can cause the driven block 21 to move along the radial direction of the elastic pen cylinder 30. In turn, the driven block 21 drives the driven plate 22 to move along the radial direction of the elastic pen cylinder 30. The driven plate 22 and the driven block 21 simultaneously exert force on the inner wall of the elastic pen cylinder 30, thereby increasing the diameter of the elastic pen cylinder 30. The driven plate 22 can provide more support for the elastic pen cylinder 30, making it easier for the user to hold the elastic pen cylinder 30.

[0059] It should be noted that in the embodiments of the present application, the number of the driven assemblies 20 can be set according to actual needs, for example, the number of the driven assemblies 20 is 6, and the 6 driven assemblies 20 are distributed along the circumferential direction of the elastic pen barrel 30, and for another example, the number of the driven assemblies 20 is 8, and the 8 driven assemblies 20 are distributed along the circumferential direction of the elastic pen barrel 30. The specific number of the driven assemblies 20 is not limited herein in the embodiments of the present application.

[0060] In addition, in some embodiments, as shown in Figure 3 The driving assembly 10 can include a driving barrel 11, the driving barrel 11 is at least partially located in the elastic pen barrel 30, and the driving barrel 11 extends along the axial direction of the elastic pen barrel 30, the outer wall of the driving barrel 11 is provided with a slot 12, the slot 12 is provided with a driving platform 13, and the driving platform 13 is provided with a first inclined surface 101; in the case that the driving barrel 11 moves along a first direction X, the driving barrel 11 drives the first inclined surface 101 to move away from the second inclined surface 201, and the driving platform 13 moves to one side of the driven block 21 in the radial direction of the elastic pen barrel 30, so that the driven assembly 20 moves along the radial direction of the elastic pen barrel 30; in the case that the driving barrel 11 moves along a second direction Y, the driving barrel 11 drives the first inclined surface 101 to move to the second inclined surface 201.

[0061] Since the driving barrel 11 is at least partially located in the elastic pen barrel 30, and the driving barrel 11 extends along the axial direction of the elastic pen barrel 30, the outer wall of the driving barrel 11 is provided with a slot 12, the slot 12 is provided with a driving platform 13, and the driving platform 13 is provided with a first inclined surface 101, therefore, the first inclined surface 101 on the driving platform 13 cooperates with the second inclined surface 201 on the driven block 21, so that when the size of the pen body of the electronic pen needs to be adjusted, the driving barrel 11 can be moved along the first direction X, the driving barrel 11 can drive the driving platform 13 to move, so that the first inclined surface 101 on the driving platform 13 can move relative to the second inclined surface 201 until the first inclined surface 101 moves away from the second inclined surface 201, at this time, the driving platform 13 will move to one side of the driven block 21 in the radial direction of the elastic pen barrel 30, that is, the driving platform 13 moves to the side of the driven block 21 away from the inner wall of the elastic pen barrel 30, so that the driving platform 13 can support the driven block 21 to a certain extent, and the driven block 21 moves along the radial direction of the elastic pen barrel 30, so that the diameter of the elastic pen barrel 30 is increased; when the size of the pen body of the electronic pen needs to be restored to the initial size, the driving barrel 11 can be moved along the second direction Y, so that the driving barrel 11 drives the driving platform 13 to move along the second direction Y, so that the first inclined surface 101 on the driving platform 13 moves to the second inclined surface 201 and cooperates with the second inclined surface 201. That is, by providing the driving barrel 11, the movement of the driven block 21 can be facilitated, and the size change of the pen body of the electronic pen is realized.

[0062] It should be noted that the driven block 21 can be partially located in the groove 12 on the outer wall of the driving cylinder 11, so that the groove 12 can avoid and limit the driven block 21 to a certain extent, so as to avoid the problem that the driven block 21 is easy to shake when moving in the radial direction of the elastic pen barrel 30, thereby affecting the diameter of the elastic pen barrel 30 when being adjusted.

[0063] In addition, in the embodiment of the present application, the number of driving platforms 13 is equal to the number of driven blocks 21.

[0064] In addition, in the embodiment of the present application, when the driven assembly 20 includes the driven plate 22, the driven plate 22 can be located between the driving cylinder 11 and the elastic pen barrel 30.

[0065] In addition, the number of grooves 12 can be equal to the number of driven blocks 21, and the arrangement of the grooves 12 is the same as that of the driven blocks 21.

[0066] In addition, in some embodiments, as shown in Figure 1 and Figure 8 The electronic pen can further include an extension pen barrel 50, the driving cylinder 11 is partially embedded in the inside of the extension pen barrel 50, and the driving cylinder 11 is connected with the extension pen barrel 50; in the axial direction of the elastic pen barrel 30, the extension pen barrel 50 and the elastic pen barrel 30 are arranged in sequence.

[0067] Through such a setting, when it is necessary to adjust the size of the pen body of the electronic pen, the user can hold the extension pen barrel 50, so as to apply force to the extension pen barrel 50, so that the extension pen barrel 50 moves in the first direction X, so that the extension pen barrel 50 drives the driving cylinder 11 to move, so that the driving cylinder 11 moves in the first direction X, that is, the driving assembly 10 moves in the first direction X, so that the diameter of the elastic pen barrel 30 increases. That is, by setting the extension pen barrel 50, the user can conveniently adjust the size of the pen body of the electronic pen.

[0068] It should be noted that the end of the extension pen barrel 50 can be in contact with the end of the elastic pen barrel 30, of course, the end of the extension pen barrel 50 can also have a gap with the end of the elastic pen barrel 30. For this, the embodiment of the present application is not limited here. Among them, in the axial direction of the extension pen barrel 50, the driving platform 13 can be located outside the extension pen barrel 50, so that when the user holds the extension pen barrel 50 and applies force to the extension pen barrel 50, the extension pen barrel 50 will not affect the driving platform 13, and ensure that the driving platform 13 can abut against the driven block 21 and apply force to the driven block 21, so that the driven block 21 moves.

[0069] In addition, in some embodiments, as shown in Figure 1 and Figure 8As shown, the electronic pen can further include a cap 60, which is arranged at the end of the extension barrel 50 away from the elastic barrel 30, and covers the opening at the end of the extension barrel 50 away from the elastic barrel 30.

Moreover, the presence of the cap 60 can also improve the aesthetic appearance of the electronic pen. That is, by arranging the cap 60, on the one hand, the aesthetic appearance of the electronic pen can be improved, and on the other hand, the components in the interior of the electronic pen can also be protected from impurities entering the interior of the electronic pen and contacting the components in the interior of the electronic pen.

[0072] By such an arrangement, the fixing platform 42 can abut against the driven block 21, so that the fixing platform 42 can block the driven block 21 from moving along the axial direction of the elastic barrel 30 when the main barrel 11 moves along the first direction X. Moreover, the presence of the fixing barrel 41 means that the fixing assembly 40 has a component with a large size, so that the fixing assembly 40 can be easily fixed, i.e. the fixing barrel 41 can be easily fixed, so that the fixing platform 42 is fixed, and the fixing platform 42 can effectively block the driven block 21.

[0073] It should be noted that the fixing barrel 41 can be provided with a fixing slot 411, which is opposite to the position of the slot 12, so that the driven block 21 can pass through the fixing slot 411. The position of the fixing slot 411 can be consistent with the position of the driven block 21.

[0074] In addition, in the embodiments of the present application, the main assembly 10 can further include a main block, the main block is connected with a rack, the rack is engaged with a gear assembly, when the gear assembly rotates, the gear assembly drives the rack to move along the first direction X or the second direction Y, so that the rack drives the main block to move along the first direction X or the second direction Y. The main block faces the driven assembly 20, so that when the main block is driven to move by the rack, the main block applies force to the driven assembly 20, so that the driven assembly 20 applies force to the inner wall of the elastic barrel 30, so that the diameter of the elastic barrel 30 increases.

[0075] It should be noted that when the electronic pen comprises the extension barrel 50, the gear assembly can be located in the extension barrel 50, and a rotary knob is arranged on the outer wall of the extension barrel 50, the rotary knob is connected with the gear assembly, and the gear assembly is driven to rotate by rotating the rotary knob, so that the gear assembly drives the rack to move.
