[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0043] Reference Figure 1The utility model embodiment provides a kind of explosion structure schematic diagram of stylus, comprising: support piece 10, touch sensor 20 and shell 30;Touch sensor 20 is arranged between support piece 10 and shell 30, and it is around support piece 10 arrangement;First protruding structure 41 is arranged on the inner wall of shell 30;The inner wall of touch sensor 20 is provided with second protruding structure 42, or the outer wall of support piece 10 is provided with second protruding structure 42;First protruding structure 41 and second protruding structure 42 are misaligned arrangement, first protruding structure 41 is attached with touch sensor 20, and it is suitable to exert extrusion force of shell 30 or support piece 10 radial inward direction y to touch sensor 20.

[0044] Wherein, exemplary, support piece 10, touch sensor 20 and shell 30 can be cylindrical structure;Touch sensor 20 is set on the outer wall of support piece 10, shell 30 is set on the outer wall of touch sensor 20, cylindrical structure is two ends open and hollow cylindrical structure, and different sizes of cylindrical structure can be nested to form an integral whole. Figure 2 , Figure 2 is Figure 1 The cross-sectional structure schematic diagram of the first embodiment of stylus, the inner diameter of support piece 10 is less than the inner diameter of touch sensor 20, the inner diameter of touch sensor 20 is less than the inner diameter of shell 30, so that touch sensor 20 can be set on the outer wall of support piece 10, shell 30 can be set on the outer wall of touch sensor 20, and the final nesting structure constitutes the main body structure of stylus.

[0045] It should be noted that touch sensor can be evenly distributed around the pen body of stylus, of course, touch sensor can also be unevenly distributed on the pen body of stylus;In addition, touch sensor can be distributed in the form of whole around the pen body of stylus, and can also be distributed in multiple parts around the pen body of stylus.The material of shell includes but is not limited to plastic material.The utility model embodiment does not limit this.

[0046] The surface of touch sensor can form capacitor, when conductive object (including but not limited to finger) approaches or moves away from touch sensor, the change of capacitance value of capacitor will be caused.This change of capacitance value makes the charge distribution in the circuit of touch sensor change, so that, through corresponding circuit design, touch sensor can detect these small capacitance changes and convert them into processable touch instructions, realize the detection of external touch input.

[0047] Based on the touch sensor, the touch detection can give the stylus more functions, such as when the touch sensor of the stylus detects a continuous touch signal, it can be considered that the current is in the scene of using the stylus, at this time the stylus can work normally; When the touch sensor of the stylus does not detect a continuous touch signal, it can be considered that the current is in the scene of not using the stylus, at this time the stylus can be in a low-power idle mode to save power.

[0048] In the embodiments of the present application, further refer to Figure 3 , Figure 3 is Figure 2 The cross-sectional enlarged view of the stylus; the support 10 is in the innermost layer in the cross-sectional structure of the stylus, the support 10 is used to provide support force from inside to outside, and the outer wall of the touch sensor 20 is sleeved with the shell 30. Specifically, the first protruding structure 41 is used to form a first gap A1 between the inner wall of the shell 30 and the outer wall of the touch sensor 20, and the second protruding structure 42 is used to form a second gap A2 between the outer wall of the support 10 and the inner wall of the touch sensor 20. Because the first protruding structure 41 and the second protruding structure 42 are arranged in a staggered manner, the first gap A1 and the second gap A2 can be arranged in a staggered manner. The second protruding structure 42 can be arranged in a stacked manner on the touch sensor 20, and can be rubber, hard or flexible plastic, etc.

[0049] Refer to Figure 2 When the conductive object (including but not limited to a finger) does not touch the surface of the shell 30, the initial distance between the touch sensor 20 and the internal support 10 is s. In this state, the distance s does not change, the touch sensor 20 remains stationary, and therefore there is no change in capacitance. When the conductive object touches the surface of the shell 30, because the first protruding structure 41 is in contact with the touch sensor 20, the pressure generated by the touch will be conducted by the first protruding structure 41 to exert a squeezing force on the touch sensor 20 in the radial inward direction y of the shell 30 or the support 10, and the squeezing force will drive the touch sensor 20 to move inward, thereby generating deformation in the second gap A2. At this time, the distance s between the touch sensor 20 and the support 10 changes. This change enables the touch sensor 20 to sense the corresponding change in capacitance and convert it into an electrical signal to achieve accurate detection of touch.

[0050] Exemplary, Figure 1 , Figure 2 , Figure 3 , Figure 4 In the scheme shown, the end of the first protruding structure 41 of the inner wall of the shell 30 is in close contact with the outer wall of the touch sensor 20, refer to Figure 1 , Figure 2 , Figure 3, the end of the second protruding structure 42 of the inner wall of the touch sensor 20 is tightly fitted with the outer wall of the support 10, or refer to Figure 4 , Figure 4 is Figure 1 The schematic diagram of the cross-sectional structure of the second embodiment of the stylus; the end of the second protruding structure 42 of the outer wall of the support 10 is tightly fitted with the inner wall of the touch sensor 20.

[0051] It should be noted that the utility model embodiment can not set an elastic member in the stylus, so that the assembly gap between each element in the stylus does not need to be absorbed by the elastic member. In the utility model embodiment, due to the design of the first protruding structure 41 and the second protruding structure 42, the end of the protruding structure arranged on one element can be tightly fitted with the surface of the adjacent other element, and the protruding structure plays a supporting role in the space between the adjacent elements, so that the effect of absorbing the assembly gap between each element in the stylus is achieved through the protruding structure.

[0052] The treatment of the assembly gap is because, if there is an assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 30, the distance detected by the touch sensor 20 will not be accurate due to the assembly gap, which will lead to a decrease in detection accuracy. Therefore, in the case that there is no assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 30, the touch sensor 20 can more accurately sense the external operation, thereby ensuring high detection accuracy and sensitivity.

[0053] In summary, in the utility model embodiment, the stylus comprises a support, a touch sensor and a shell, the utility model is provided with a first protruding structure on the inner wall of the shell; a second protruding structure is arranged on the inner wall of the touch sensor, or a second protruding structure is arranged on the outer wall of the support; the first protruding structure and the second protruding structure are arranged in a staggered manner, the first protruding structure is fitted with the touch sensor and is suitable for applying a radially inward extrusion force of the shell or the support to the touch sensor, gaps are formed between adjacent first protruding structures and between adjacent second protruding structures, and the triggering of the touch sensor by external force is realized through the gaps, so that the stylus is more likely to detect the distance change between the conductive object and the touch sensor under the action of external force, the detection accuracy and sensitivity of the touch sensor are improved, and in addition, the utility model also absorbs the assembly gap between the touch sensor and the shell by arranging the protruding structure, so that the outer wall of the touch sensor is tightly fitted with the inner wall of the shell and does not slip, and the detection accuracy and sensitivity are further improved.

[0054] Optionally, refer to Figure 1 The first protruding structure 41 is a strip-shaped structure; the length extension direction of the first protruding structure 41 is consistent with the axial direction z of the shell 30; further refer to Figure 2The space formed between adjacent first protruding structures 41 constitutes a first gap A1.

[0055] In the embodiment of the present application, the inner wall of the shell 30 is provided with a plurality of first protruding structures 41 spaced from each other, such as Figure 1 , Figure 2 In the embodiment of the present application, the inner wall of the shell 30 is provided with 6 first protruding structures 41 spaced from each other, but the number of the first protruding structures 41 is not limited in the embodiment of the present application. The plurality of first protruding structures 41 are evenly distributed in the radial direction of the shell 30 on the inner wall of the shell 30, and with reference to Figure 1 The first protruding structure 41 is a strip-shaped structure, and the length extension direction of the first protruding structure 41 is consistent with the axial direction z of the shell 30 of the cylindrical structure, so that the space formed between adjacent first protruding structures 41 constitutes a first gap A1.

[0056] In addition, when the conductive object presses the shell 30, such as pressing the position corresponding to the first protruding structure 41, the shell 30 will be pressed and deformed at the first gap A1, and the first gap A1 can also absorb the pressing deformation at this position, so as to avoid the touch sensor 20 detecting a touch signal at the position corresponding to the first protruding structure 41, thereby avoiding the false touch at the position of the first gap A1.

[0057] Optionally, with reference to Figure 1 The second protruding structure 42 is a strip-shaped structure; the length extension direction of the second protruding structure 42 is consistent with the axial direction z of the touch sensor 20 or the support 10; further with reference to Figure 2 The space formed between adjacent second protruding structures 42 constitutes a second gap A2; the second protruding structure 42 is correspondingly arranged with the first gap A1; the first protruding structure 41 is correspondingly arranged with the second gap A2; and the first protruding structure 41 is adapted to be pressed against the outer wall of the touch sensor 20 under the action of external force, so that the touch sensor 20 is deformed in the second gap A2.

[0058] In the first embodiment of the present application, a plurality of second protruding structures 42 spaced from each other can be arranged on the inner wall of the touch sensor 20, such as Figure 2 and Figure 3In the embodiment, the inner wall of the touch sensor 20 is provided with six second protruding structures 42 which are spaced apart from each other, but the number of the second protruding structures 42 is not limited in the embodiment. The plurality of second protruding structures 42 are evenly distributed on the inner wall of the touch sensor 20 in the radial direction of the touch sensor 20, and the second protruding structures 42 can also be strip structures, and the length extension direction of the second protruding structures 42 is consistent with the axial direction z of the touch sensor 20 in the cylindrical structure, so that the space formed between the adjacent second protruding structures 42 and the outer wall of the support 10 forms a second gap A2. When the conductive object does not touch the surface of the shell 30, the initial distance between the touch sensor 20 and the internal support 10 is s. In this state, the distance s does not change, and the touch sensor 20 remains stationary, so there is no change in capacitance. When the conductive object touches the surface of the shell 30, since the first protruding structure 41 is attached to the touch sensor 20, the pressure generated by the touch will be conducted by the first protruding structure 41 to exert a pressing force on the touch sensor 20 in the radial inward direction y of the shell 30 or the support 10, so that the pressure generated by the touch will drive the touch sensor 20 to move inward, and deformation is generated in the second gap A2, at this time, the distance s between the touch sensor 20 and the support 10 changes. This change enables the touch sensor 20 to sense the corresponding change in capacitance and convert it into an electrical signal to achieve accurate detection of touch.

[0059] In the second embodiment of the utility model, refer to Figure 4 A plurality of second protruding structures 42 which are spaced apart from each other can be arranged on the outer wall of the support 10, for example Figure 4 In the embodiment, the outer wall of the support 10 is provided with six second protruding structures 42 which are spaced apart from each other, but the number of the second protruding structures 42 is not limited in the embodiment. The plurality of second protruding structures 42 are evenly distributed on the inner wall of the support 10 in the radial direction of the support 10, and the second protruding structures 42 can also be strip structures, and the length extension direction of the second protruding structures 42 is consistent with the axial direction z of the support 10 in the cylindrical structure, so that the space formed between the adjacent second protruding structures 42 and the inner wall of the touch sensor 20 forms a second gap A2. In the cooperation of the second protruding structure 42 and the first protruding structure 41 arranged on the inner wall of the shell 30, since the projection of the second protruding structure 42 on the shell 30 is in the first gap A1 (the second protruding structure 42 is correspondingly arranged with the first gap A1); the projection of the first protruding structure 41 on the support 10 is in the second gap A2 (the first protruding structure 41 is correspondingly arranged with the second gap A2), so that the pressing of the conductive object on the shell 30 will make the pressure transmitted to the position of the touch sensor 20 corresponding to the second gap A2 through the end of the first protruding structure 41, so that the structure of the touch sensor 20 at the position of the second gap A2 is deformed, and the deformation can trigger the touch sensor 20 to detect the touch signal.

[0060] In the first and second embodiments of the utility model, the positions of the first gap A1 and the second gap A2 can be staggered with each other. Preferably, the projection of the second protruding structure 42 on the shell 30 completely coincides with the first gap A1, and the projection of the first protruding structure 41 on the touch sensor 20 completely coincides with the second gap A2. In this way, the first protruding structure 41 can overlap the position of the second gap A2, and when the conductive object presses the shell 30, the pressure transmitted by the end of the first protruding structure 41 can directly change the depth of the second gap A2, so that the distance between the touch sensor 20 and the support 10 at the pressing position changes. This change enables the touch sensor 20 to more easily sense the corresponding change in capacitance and convert it into an electrical signal to achieve accurate detection of touch.

[0061] Optionally, referring to Figure 2 to Figure 5 When the touch sensor 20 and the support 10 are assembled in the shell 30, the first protruding structure 41 is adapted to extrude the outer wall of the touch sensor 20, so that the touch sensor part at the extrusion position is sunken in the inward direction y of the radial direction of the touch sensor, and the touch sensor part at the corresponding position of the first gap A1 is extruded to fill the first gap A1.

[0062] For the assembly of the stylus, the shell 30 and the touch sensor 20 in the assembled stylus need to be tightly attached to each other without position slippage, i.e. to eliminate the assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 30, and to ensure that the touch sensor 20 does not deviate from the position relative to the shell 30, so as to ensure the detection accuracy and sensitivity of the touch sensor 20. The assembly gap is processed because if there is an assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 30, the detection distance of the touch sensor 20 will not be accurate due to the assembly gap, which will lead to a decrease in detection accuracy. Therefore, in the case where there is no assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 30, the touch sensor 20 can more accurately sense the external operation, thereby ensuring high detection accuracy and sensitivity.

[0063] In the embodiment of the utility model, when the touch sensor 20 and the supporting piece 10 are assembled in the shell 30, the shell 30 generates the extrusion force in the radial inward direction y through the first protruding structure 41, the extrusion force can be suitable for extruding the outer wall of the touch sensor 20, so that the touch sensor part at the extrusion position is sunken in the radial inward direction y of the touch sensor 20, and this sunken effect can make the shell 30 and the touch sensor 20 closely adhere to each other and eliminate the assembly gap at the contact position. In addition, the sunken touch sensor part caused by the extrusion of the first protruding structure 41 can further cause the touch sensor part at the position corresponding to the first gap A1 to be extruded and thus fill the first gap A1, and after filling, the touch sensor part filled is limited by the two side walls of the first gap A1, so that the effect of mutual positioning and installation of the shell 30 and the touch sensor 20 can be achieved, so that the touch sensor 20 will not be positionally deviated relative to the shell 30, and the high detection precision and detection sensitivity of the touch sensor 20 are ensured.

[0064] For example, referring to Figure 3 In the first embodiment of the utility model, the second protruding structure 42 is arranged on the inner wall of the touch sensor 20, before the shell 30 and the touch sensor 20 are assembled, the outer wall surface of the part of the touch sensor 20 corresponding to the first protruding structure 41 is at position S2, after the shell 30 and the touch sensor 20 are assembled, the outer wall surface of the corresponding part of the touch sensor 20 is sunken in the radial inward direction y and moves to position S2' under the extrusion of the first protruding structure 41, and this extrusion and sinking of the part of the touch sensor 20 can eliminate the assembly gap at the contact position. In addition, under the influence of the extrusion and sinking of the part of the touch sensor 20 corresponding to the first protruding structure 41, the outer wall surface S1 of the part of the touch sensor 20 corresponding to the first gap A1 is moved upward in the radial outward direction x, so that the part of the touch sensor 20 corresponding to the first gap A1 fills the first gap A1, and the assembly and positioning of the touch sensor and the shell are realized.

[0065] For example, referring to Figure 5In the second embodiment of the present application, the second protruding structure 42 is arranged on the outer wall of the supporting member 10. Before the shell 30 and the touch sensor 20 are assembled, the outer wall surface of the part of the touch sensor 20 corresponding to the first protruding structure 41 is at position S3. After the shell 30 and the touch sensor 20 are assembled, the part of the touch sensor 20 is extruded by the first protruding structure 41, the outer wall surface of the corresponding part of the touch sensor 20 is depressed in the radial inward direction y, and is moved to position S3'. The extrusion and depression of the part of the touch sensor 20 can eliminate the assembly gap at the contact position. In addition, the outer wall surface S1 of the part of the touch sensor 20 corresponding to the first gap A1 is moved upward in the radial outward direction x due to the extrusion and depression of the part of the touch sensor 20 corresponding to the first protruding structure 41, so that the part of the touch sensor 20 corresponding to the first gap A1 fills the first gap A1, and the assembly positioning of the touch sensor and the shell is realized.

[0066] It should be noted that, for the first embodiment and the second embodiment of the present application, after the part of the touch sensor 20 corresponding to the first gap A1 is filled in the first gap A1, the outer wall surface S1 of the part of the touch sensor 20 corresponding to the first gap A1 can be tightly attached to the bottom wall of the first gap A1, or the outer wall surface S1 of the part of the touch sensor 20 corresponding to the first gap A1 can be spaced apart from the bottom wall of the first gap A1 by a small distance, and the present application does not make a specific limitation on this.

[0067] Optionally, referring to Figure 6 , Figure 6 is Figure 2 Another cross-sectional enlarged view of the stylus, the outer wall of the touch sensor 20 is provided with a third protruding structure 43 matched with the shape of the first gap A1 at the position corresponding to the first gap A1; the third protruding structure 43 is a strip-shaped structure; the length extension direction of the third protruding structure 43 is consistent with the axial direction of the touch sensor 20; the opposite sides of the surface of the third protruding structure 43 in contact with the shell 30 are rounded structures; when the touch sensor 20 and the supporting member 10 are assembled in the shell 30, the first protruding structure 41 is adapted to extrude the outer wall of the touch sensor 20, so that the part of the touch sensor at the extrusion position is depressed in the radial inward direction y of the touch sensor, and the third protruding structure 43 fills the first gap. The third protruding structure is stacked with the touch sensor 20, and the material thereof can be rubber, hard or flexible plastic, etc.

[0068] In the present application Figure 6In the embodiment, the outer wall of the touch sensor 20 is provided with a third protruding structure 43 matching the shape of the first gap A1 at the position corresponding to the first gap A1, when the touch sensor 20 and the support 10 are assembled in the shell 30, the shell 30 can generate a pressing force in the radial inward direction y through the first protruding structure 41, so that the touch sensor part at the pressing position is depressed, thereby eliminating the assembly gap at the contact position. In addition, the third protruding structure 43 of the outer wall of the touch sensor 20 fills the first gap A1, and after filling, the third protruding structure 43 is limited by the two side walls of the first gap A1, which can achieve the effect of mutual positioning of the shell 30 and the touch sensor 20, so that the touch sensor 20 does not deviate from the shell 30, thereby ensuring the high detection accuracy and detection sensitivity of the touch sensor 20.

[0069] In the third protruding structure 43, the opposite sides of the surface for contacting the shell 30 are rounded structures, which can reduce the mutual abrasion between the third protruding structure 43 and the inner wall of the shell 30.

[0070] Optionally, referring to Figure 2 to Figure 5 The cross-sectional shape of the first gap A1 is trapezoidal, and the cross-sectional width of the first gap A1 uniformly increases along the radial inward direction y of the shell 30, and the cross-sectional shape of the first protruding structure 41 is trapezoidal, and the cross-sectional width of the first protruding structure 41 uniformly decreases along the radial inward direction y of the shell 30.

[0071] In the first embodiment and the second embodiment of the utility model, the cross-sectional shape of the first protruding structure 41 can be trapezoidal, and the cross-sectional width of the first protruding structure 41 uniformly decreases along the radial inward direction y of the shell 30, so that the cross-sectional shape of the first gap A1 formed between adjacent first protruding structures 41 is also trapezoidal, and the cross-sectional width of the first gap A1 uniformly increases along the radial inward direction y of the shell 30. The advantage of the first protruding structure 41 with a trapezoidal cross section is that when the first protruding structure 41 presses the corresponding part of the touch sensor 20, the trapezoidal structure of the first protruding structure 41 can reduce the damage to the corresponding part of the touch sensor 20, and in addition, the trapezoidal structure of the first protruding structure 41 can also extrude and guide the part of the touch sensor 20 corresponding to the first gap A1, so that the part of the touch sensor 20 corresponding to the first gap A1 is more easily filled in the first gap A1.

The advantage of the second protruding structure 42 with trapezoidal cross-section is that when the first protruding structure 41 presses the corresponding part of the touch sensor 20, the part of the touch sensor 20 pressed can be deformed in the second gap A2, at this time, the trapezoidal structure of the second gap A2 can play a guiding role for the deformed part of the touch sensor 20, so that the deformation of the touch sensor 20 is more likely to occur, and the detection sensitivity and accuracy of the touch sensor are improved.

[0078] In the embodiment of the present application, the first protruding structure and the shell can be an integrated structure, and the second protruding structure and the touch sensor or the support member can be an integrated structure, so that the shell and the touch sensor or the support member can be integrally processed and formed, thereby reducing the production cost and improving the production efficiency. In addition, the first protruding structure and the shell can also be separate structures, and the second protruding structure and the touch sensor or the support member can also be separate structures, thereby further increasing the flexibility of the protruding structure.
