In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0040] Next, with reference to the accompanying drawings of the specification, the electronic pen according to the first aspect embodiment of the present utility model will be described.

[0041] Refer to Figure 1 and Figure 2 As shown, the embodiment of the present utility model provides an electronic pen, wherein the electronic pen includes a housing 100, a main body portion 200, and an adjustment assembly 300. The housing 100 defines a receiving cavity 111, and the adjustment assembly 300 and at least a part of the main body portion 200 are disposed in the receiving cavity 111. The interior of the housing 100 further includes a first limiting portion 121, and the first limiting portion 121 is disposed in the receiving cavity 111. The first limiting portion 121 is used to limit the movement of the main body portion 200 and the adjustment assembly 300.

[0042] The main body portion 200 is movably connected to the housing 100. The main body portion 200 includes a pen tip 210 and a main shaft member 220. The pen tip 210 is detachably connected to the main shaft member 220. Among them, a part of the main shaft member 220 is located in the receiving cavity 111, and the pen tip 210 and the main shaft member 220 can move relative to the housing 100 in the receiving cavity 111 along the axial direction of the housing 100.

[0043] The adjustment assembly 300 is movably connected to the main shaft member 220. Among them, when the pen tip 210 and the main shaft member 220 are connected, the adjustment assembly 300 abuts against the pen tip 210, so that the pen tip 210 and the housing 100 are spaced apart, and a first gap h1 is formed between the pen tip 210 and the housing 100. The adjustment assembly 300 is disposed between the pen tip 210 and the first limiting portion 121. The pen tip 210, the adjustment assembly 300, and the first limiting portion 121 are arranged in sequence along the axial direction of the housing 100. The adjustment assembly 300 and the first limiting portion 121 are spaced apart, and a second gap h2 is formed between them.

[0044] Specifically, the pen tip 210 forms a connection with the main shaft member 220 in the accommodation cavity 111. The adjustment assembly 300 is connected to the main shaft member 220. When the pen tip 210 is assembled to the main shaft member 220, it will abut against the adjustment assembly 300. The adjustment assembly 300 will prevent the pen tip 210 from moving. At this time, the pen tip 210 and the housing 100 are not in contact, and a first gap h1 is formed between them. At the same time, the adjustment assembly 300 is also spaced from the first limiting portion 121 in the accommodation cavity 111, and a second gap h2 is formed between them. When using the electronic pen, the pen tip 210 will be squeezed due to writing. Under the action of the squeezing force, the pen tip 210 will drive the main shaft member 220 to move axially along the housing 100 relative to the housing 100. Since the adjustment assembly 300 is arranged on the main shaft member 220, the adjustment assembly 300 will also move axially along the housing 100 together with the main shaft member 220. During the movement, the second gap h2 will decrease until the adjustment assembly 300 abuts against the first limiting portion 121, that is, when the second gap h2 is reduced to zero, after abutting, the first limiting portion 121 will limit the movement of the main shaft member 220 by hindering the movement of the adjustment assembly 300.

[0045] When using the electronic pen, the electronic pen needs to communicate with the electronic device for writing. The electronic pen needs to generate pressure sensitivity by squeezing the pen tip 210. That is, when the electronic pen is in contact with the electronic device for writing, the contact between the two will generate pressure on the pen tip 210. The electronic pen generates pressure sensitivity through this pressure, so that the electronic pen can be used normally on the electronic device. Therefore, a certain gap needs to be ensured between the pen tip 210 and the housing 100 during assembly so that the pen tip 210 can have a moving distance when being squeezed. The adjustment assembly 300 can limit the gap between the pen tip 210 and the housing 100 to ensure that the gap distance between the two meets the assembly requirements. At the same time, the adjustment assembly 300 and the first limiting portion 121 are spaced apart to form the second gap h2, which can give the main shaft member 220 a certain moving space. And restricting the movement of the main shaft member 220 by the first limiting portion 121 can prevent the situation that when the pen tip 210 is pressed to drive the main shaft member 220 to move, the main shaft member 220 undergoes irreversible plastic deformation due to excessive moving distance. Therefore, this electronic pen can solve the problem that traditional electronic pens do not have enough moving space between parts due to manufacturing tolerances, and the parts are squeezed against each other during use, resulting in deformation of the electronic pen. Moreover, the adjustment assembly 300 is movably connected to the main shaft member 220, and the position of the adjustment assembly 300 can also be adjusted to prevent the gap between the parts in the electronic pen from being too large, which affects the accuracy and stability of the electronic pen, resulting in inaccurate graphics drawn or the electronic pen being unable to be used.

[0046] In some embodiments, refer to Figure 3 and Figure 4As shown, the pen tip 210 includes a pen tip 211 and a connecting portion 212, the pen tip 211 is connected to the connecting portion 212, the pen tip 211 is located outside the accommodating cavity 111, and the connecting portion 212 is located in the accommodating cavity 111 and is detachably connected to the main shaft member 220. Specifically, when the pen tip 210 is connected to the main shaft member 220 through the connecting portion 212, the connecting portion 212 will drive the pen tip 211 to move along the axial direction of the shell 100, and the adjustment assembly 300 will abut the connecting portion 212 to limit the movement of the connecting portion 212. When the connecting portion 212 is restricted, the pen tip 211 will be spaced apart from the shell 100, thereby defining a first gap h1 together with the shell 100. For further information, see Figure 4 As shown, the connecting portion 212 is provided with a mounting opening 2121 around its outer surface, and the mounting opening 2121 is recessed relative to the outer surface of the connecting portion 212. The mounting opening 2121 is used to connect a jig, so as to facilitate the use of the jig to fix the pen tip 210 on the main shaft 220. The pen tip 210 can be connected to the main shaft 220 through the mounting opening 2121.

[0047] In some embodiments (not shown in the figure), the positional relationship between the pen tip 210 and the main shaft 220 in the accommodating chamber 111 can also be other situations. For example: a part of the main shaft 220 is arranged in the accommodating chamber 111, while the pen tip 210 is not arranged in the accommodating chamber 111, a part of the main shaft 220 extends out of the accommodating chamber 111, the pen tip 210 is connected to the part of the main shaft 220 located outside the accommodating chamber 111, and one end of the adjustment component 300 is arranged at the end of the accommodating chamber 111, that is, the open end 113 of the housing 100. The adjustment component 300 abuts against the pen tip 210 at the open end 113 so that the pen tip 210 and the housing 100 are spaced apart. At the same time, the adjustment component 300 also limits the movement of the pen tip 210 and limits the pen tip 210 from entering the accommodating chamber 111.

[0048] Furthermore, in this embodiment, the pen tip 210 is connected to the main shaft 220 through a threaded connection portion 212. In other embodiments (not shown in the figure), the connection portion 212 can also be detachably connected to the main shaft 220 by a snap connection, or bonding or the like. In another embodiment (not shown in the figure), the pen tip 210 can also be fixedly connected to the main shaft 220, such as: one-piece injection molding, or welding or the like. The use of a fixed connection method requires the distance between the pen tip 210 and the housing 100 to be positioned in advance, thereby also allowing the width of the gap between the pen tip 210 and the housing 100 to meet the requirements.

[0049] In some embodiments, see Figure 2 , Figure 3 and Figure 5As shown, the adjusting assembly 300 includes a first adjusting member 310 and a second adjusting member 320 which are oppositely arranged. The first adjusting member 310 and the second adjusting member 320 are movably connected to the main shaft member 220. Among them, the first adjusting member 310 abuts against the connecting portion 212, and the second adjusting member 320 and the first limiting portion 121 are arranged at an interval along the axial direction of the housing 100 to jointly define a second gap h2. Specifically, both the first adjusting member 310 and the second adjusting member 320 are arranged on the main shaft member 220. When the pen tip 210 is connected to the main shaft member 220 through the connecting portion 212, the first adjusting member 310 will abut against the connecting portion 212, and the first adjusting member 310 is used to limit the movement of the pen tip 210. The second adjusting member 320 is arranged close to the first limiting portion 121, and the second adjusting member 320 and the first limiting portion 121 are arranged at an interval, and the two jointly define a second gap h2.

[0050] Furthermore, in this embodiment, the main shaft member 220 is provided with an external thread structure arranged along the axial direction of the housing 100. At least a part of the external thread structure is located in the accommodation cavity 111. The first adjusting member 310 and the second adjusting member 320 are two nuts. The first adjusting member 310 and the second adjusting member 320 are threadedly connected to the external thread structure, so as to be movably arranged on the main shaft member 220. In some embodiments (not shown in the figure), the first adjusting member 310 and the second adjusting member 320 can also be other structural members, such as: a slider. A slide rail is arranged on the main shaft member 220, and the slider can move and be positioned on the slide rail, so as to limit the movement of the pen tip 210 and abut against the first limiting portion 121. In other embodiments (not shown in the figure), the number of adjusting members included in the adjusting assembly 300 can be other numbers, such as: the adjusting assembly 300 only includes one adjusting member, and this adjusting member simultaneously abuts against the connecting portion 212 of the pen tip 210 and is arranged at an interval from the first limiting portion 121, or the adjusting assembly 300 includes three or other numbers of adjusting members with such characteristics. In another embodiment (not shown in the figure), the adjusting assembly 300 can also be a convex block formed by extending outward from the main shaft member 220, and the movement of the pen tip 210 is limited and abuts against the first limiting portion 121 through the convex block.

[0051] In some embodiments, refer to Figure 2 and Figure 5As shown, the adjusting assembly 300 is provided with an adjusting opening 330 along its outer wall surface. Both the first adjusting member 310 and the second adjusting member 320 are provided with the adjusting opening 330. The adjusting opening 330 is circumferentially arranged on the outer wall surfaces of the first adjusting member 310 and the second adjusting member 320, and the adjusting opening 330 penetrates through the first adjusting member 310 and the second adjusting member 320 along the thickness direction of the outer wall surfaces of the first adjusting member 310 and the second adjusting member 320. The adjusting opening 330 is used to connect the jig, which is convenient for using the jig to fix the adjusting assembly 300. By the adjusting opening 330, the positions of the first adjusting member 310 and the second adjusting member can be adjusted, thereby changing the sizes of the first gap h1 and the second gap h2. Among them, the first gap h1 is greater than the second gap h2. Since the electronic pen needs to sense pressure to work, and the pressure sensing needs to be realized through the pen tip 210, making the first gap h1 greater than the second gap h2 can enable the second adjusting member 320 to abut against the first limiting portion 121. That is, when the second gap h2 is zero, there is still a moving distance between the pen tip 210 and the housing 100, and the pen tip 210 will not directly abut against the housing 100, thereby preventing the pen tip 210 and the housing 100 from being squeezed against each other when the pen tip 210 is pressed, thus causing damage to the pen tip 210 and the sensing element.

[0052] In some embodiments, referring to Figure 2 and Figure 3 As shown, the housing 100 includes an outer shell 110 and a first limiting member 120. The outer shell 110 is used to define an accommodation cavity 111. The first limiting member 120 is removably accommodated in the accommodation cavity 111, that is, the first limiting member 120 is detachably arranged in the accommodation cavity 111 and connected to the inner wall of the outer shell 110. A first limiting portion 121 is formed on the first limiting member 120. Specifically, when the main shaft member 220 is assembled into the accommodation cavity 111, the main shaft member 220 will be connected to the first limiting member 120, and the first limiting portion 121 will limit the movement of the main shaft member 220, so that the first limiting member 120 axially positions the main shaft member 220, so that at least a part of the main shaft member 220 is always kept in the accommodation cavity 111. When the main shaft member 220 moves in the accommodation cavity 111, when it moves a certain distance, the first limiting portion 121 on the first limiting member 120 will limit the movement of the main shaft member 220 to prevent the main shaft member 220 from undergoing plastic deformation.

[0053] In other embodiments (not shown in the figure), the housing 100 may not include the first limiting member 120. Among them, the first limiting member 120 is arranged on the inner wall of the outer shell 110, and the first limiting member 120 extends from the inner wall of the outer shell 110 towards the position where the main shaft member 220 is located. Thus, when the main shaft member 220 moves in the accommodation cavity 111, the outer shell 110 will limit the movement of the main shaft member 220 through the first limiting portion 121.

[0054] In some embodiments, referring to Figure 8As shown, a limiting structure 112 is provided around the inner wall of the outer shell 110. The number of the limiting structures 112 is multiple. The limiting structures 112 protrude in the direction of the central axis of the outer shell 110. The protruding distances of the multiple limiting structures 112 are different. The multiple limiting structures 112 together form a stepped structure. The stepped structure can facilitate the assembly of the first limiting member 120, meet the axial positioning requirement of the first limiting member 120, so that the first limiting member 120 can be connected and fixed in the accommodation cavity 111, and then position the main shaft member 220 through the first limiting member 120. The first limiting member 120 is connected and fixed to the limiting structure 112. Among them, the limiting structure 112 is configured to limit the movement of the first limiting member 120 in the direction of the pen tip 210. That is: the pen tip 210 is assembled from the opening end 113 of the outer shell 110 into the accommodation cavity 111. The limiting structure 112 can be used to position the first limiting member 120 and prevent the first limiting member 120 from moving out of the opening end 113 of the outer shell 110 and separating from the outer shell 110.

[0055] In some embodiments, referring to Figure 6 and Figure 7 As shown, a first limiting portion 121 extends from the side of the first limiting member 120 facing the main shaft member 220, and the first limiting portion 121 defines a moving channel 122. Specifically, a part of the inner wall of the first limiting member 120 protrudes and extends in the direction of the central axis of the outer shell 110. The first limiting portion 121 is formed around the inner wall of the first limiting member 120. The first limiting portion 121 is a cylindrical structure with a hollow structure. Among them, the hollow structure of the first limiting portion 121 defines the moving channel 122, and the inner diameter of the hollow structure is smaller than the inner diameter of the second adjusting member 320. A part of the main shaft member 220 is inserted into the moving channel 122. When the pen tip 210 drives the main shaft member 220 to move axially along the housing 100, the main shaft member 220 can move in the moving channel 122. When the second adjusting member 320 also moves to the position of the moving channel 122, due to the relationship of its inner diameter size, the first limiting portion 121 will abut against the second adjusting member 320 to prevent the second adjusting member 320 from entering the moving channel 122, thereby restricting the movement of the main shaft member 220.

[0056] In other embodiments (not shown in the figure), the first limiting portion 121 may also be formed by a plurality of protruding portions protruding from the inner wall of the first limiting member 120 in the direction of the central axis of the outer shell 110. The plurality of protruding portions are circumferentially arranged at intervals on the inner wall of the first limiting member 120. One ends of the plurality of protruding portions close to the central axis of the outer shell 110 do not contact each other, thereby forming a moving channel 122. The size of the moving channel 122 is smaller than the size of the second adjusting member 320, thereby restricting the second adjusting member 320 from entering the moving channel 122.

[0057] In another embodiment (not shown in the figures), the first limiting portion 121 may also be a limiting block formed by protruding from the inner wall of the first limiting member 120 towards the central axis of the housing 110, and the protruding distance of the limiting block is greater than the distance from the second adjusting member 320 to the inner wall of the first limiting member 120, so that the limiting block can abut against the limiting block when moving.

[0058] In some embodiments, referring to Figure 6 As shown, a through hole 123 is provided on the outer wall surface of the first limiting member 120, and the through hole 123 penetrates the outer wall surface of the first limiting member 120. The adjusting assembly 300 can be directly adjusted through the through hole 123, which is convenient for changing the sizes of the first gap h1 and the second gap h2.

[0059] In some embodiments, referring to Figure 3 and Figure 6 As shown, the main body portion 200 further includes a second limiting member 230. The main shaft member 220 includes a first end and a second end. Among them, the first end of the main shaft member 220 is connected to the pen tip 210, and the second limiting member 230 is connected to the second end. Further, a second limiting portion 231 is formed by extending from the side of the second limiting member 230 facing the housing 110, that is, the second limiting member 230 extends towards the inner wall of the housing 110 to form the second limiting portion 231. The second limiting portion 231 and the adjusting assembly 300 are respectively arranged at intervals on both sides of the moving channel 122 formed by the first limiting portion 121. Specifically, referring to Figure 2 As shown, the second limiting portion 231 extends towards the inner wall of the housing 110, and the width of the second limiting portion 231 is greater than the width of the moving channel 122. Therefore, the second limiting portion 231 cannot enter the moving channel 122 either, and the second limiting portion 231 and the adjusting assembly 300 are separated by the first limiting portion 121. The second limiting portion 231 can prevent the main shaft member 220 from moving out of the accommodating cavity 111 along the axial direction of the housing 100 from the opening end 113, and at the same time, it can also axially position the first limiting member 120 to prevent the first limiting member 120 from moving out of the accommodating cavity 111 along the axial direction of the housing 100 from the side far away from the opening end 113. The main body portion 200 and the first limiting member 120 limit each other through the second limiting member 230 to mutually ensure the axial positioning of each other in the accommodating cavity 111.

[0060] In another embodiment (not shown in the figures), the second limiting member 230 may be a baffle plate, which is connected to the second end of the main shaft member 220 and extends towards the inner wall of the housing 110 and abuts against the inner wall of the housing 110. Since the baffle plate abuts against the inner wall of the housing 110, while the first limiting portion 121 extends away from the inner wall of the housing 110 and towards the central axis of the housing 110, the width of the baffle plate will surely be greater than the width of the moving channel 122, and the baffle plate cannot pass through the moving channel 122. The baffle plate and the adjusting assembly 300 are separated by the first limiting portion 121, thereby preventing the first limiting member 120 from moving out of the receiving cavity 111 from the side away from the opening end 113.

[0061] In some embodiments, referring to Figure 6 as shown, the electronic pen further includes a control module and a strain gauge assembly 400. Among them, the adjusting assembly 300 in the electronic pen is only applied to the architecture with the strain gauge assembly 400. The strain gauge assembly 400 is connected to the main shaft member 220, and the control module is located in the receiving cavity 111 and is electrically connected to the main shaft member 220 through the strain gauge assembly 400. Specifically, referring to Figures 1 to 8 as shown, the housing 100 of the adjusting assembly 300 defines the receiving cavity 111. Among them, the control module, the adjusting assembly 300, the strain gauge assembly 400 and at least a part of the main shaft member 220 are arranged in the receiving cavity 111. The control module is connected to the strain gauge assembly 400 and is electrically connected to the main shaft member 220 through the strain gauge assembly 400. The control module is used to receive the pressure sensation received by the pen tip 210, so as to drive the electronic pen to work.

[0062] In some embodiments, the control modules of different electronic pens are different. After the control module is arranged in the receiving cavity 111, it is necessary to adjust the gaps between the components in the electronic pen through the adjusting assembly 300 so that the gaps between the components meet the requirements and avoid plastic deformation of the electronic pen during use. The adjusting assembly 300 can prevent the electronic pen from being damaged due to tolerance accumulation and can be adapted to the components and user requirements of different electronic pens.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention. In addition, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
