[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally of one kind and are not limited in number. For example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0037] Referring to Figure 1 , the present application provides an explosion structure diagram of a stylus, the stylus comprising: a support 10, a touch sensor 20, an elastic member 30 and a housing 40; the touch sensor 20 is arranged around the support 10, the elastic member 30 is arranged between the housing 40 and the touch sensor 20, the elastic member 30 is extruded by the housing 40 and the touch sensor 20, and generates deformation along the radial direction of the housing 40 and / or the support 10 (such as Figure 1 and Figure 2 , the direction x is the radial outward direction of the housing 40 or the support 10, and the direction y is the radial inward direction of the housing 40 or the support 10); referring to Figure 2 , the support 10 is provided with a gap A, the touch sensor 20 at least partially covers the gap A, and the gap is used to provide a space for the touch sensor 20 which generates deformation when extruded and deformed by an external force. Preferably, the touch sensor 20 completely covers the gap A.

[0038] Exemplarily, the support 10, the touch sensor 20, the elastic member 30 and the shell 40 can be a cylindrical structure; the touch sensor 20 is sleeved on the outer wall of the support 10, the elastic member 30 is sleeved on the outer wall of the touch sensor 20, the shell 40 is sleeved on the outer wall of the elastic member 30, and the cylindrical structure is a hollow cylindrical structure with both ends open, and cylindrical structures of different sizes can be nested with each other to form an integral whole.

[0039] In the embodiment of the utility model, exemplarily, with reference to Figure 2 The inner diameter of the support 10 is smaller than the inner diameter of the touch sensor 20, the inner diameter of the touch sensor 20 is smaller than the inner diameter of the elastic member 30, and the inner diameter of the elastic member 30 is smaller than the inner diameter of the shell 40, so that the touch sensor 20 can be sleeved on the outer wall of the support 10, the elastic member 30 can be sleeved on the outer wall of the touch sensor 20, and the shell 40 can be sleeved on the outer wall of the elastic member 30, and finally the nested structure constitutes the main structure of the stylus.

[0040] It should be noted that the touch sensors can be uniformly distributed around the pen body of the stylus, of course, the touch sensors can also be unevenly distributed on the pen body of the stylus; in addition, the touch sensors can be distributed in the form of a whole around the pen body of the stylus, or can be distributed in multiple parts around the pen body of the stylus. The material of the shell includes but is not limited to plastic material. The embodiment of the utility model does not limit this.

[0041] The surface of the touch sensor can form a capacitor, and when a conductive object (including but not limited to a finger) approaches or moves away from the touch sensor, the capacitance value of the capacitor will change. This change in capacitance value causes a change in the charge distribution in the circuit of the touch sensor, so that through the corresponding circuit design, the touch sensor can detect these small changes in capacitance and convert them into processable touch instructions, realizing the detection of external touch input.

[0042] Based on the touch detection of the touch sensor, the stylus can be given more functions, for example, 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.

[0043] In the embodiment of the utility model, with reference to Figure 2The support 10 is in the innermost layer in the cross-sectional structure of the stylus, and is used to provide support force from inside to outside. The outer wall of the touch sensor 20 is sleeved with the elastic member 30, so that the elastic member 30 is between the touch sensor 20 and the shell 40. The two surfaces of the elastic member 30 are tightly attached to the outer wall of the touch sensor 20 and the inner wall of the shell 40 respectively, so that the elastic member 30 can absorb the assembly gap between the touch sensor 20 and the shell 40. In addition, the elastic member can also provide pressure from outside to inside, so that the touch sensor 20 and the support 10 are in close contact. If there is an assembly gap between the outer wall of the touch sensor 20 and the inner wall of the shell 40, the distance detected by the touch sensor 20 will not be accurate due to the assembly gap, which will reduce the 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 40, the touch sensor 20 can more accurately sense the external operation, thereby ensuring high detection accuracy and sensitivity. In addition, the elastic member can be foam, silicone, adhesive and the like.

[0044] When the conductive object does not touch the shell 40, the initial distance between the touch sensor 20 and the inner 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 position corresponding to the gap A in the shell 40, the external pressure generated by the conductive object will be conducted to the inner layer by the elastic member 30, causing the touch sensor 20 to deform radially inward at the position corresponding to the gap A. The gap A will provide a space for the deformation to occur smoothly, so that the distance between the touch sensor 20 and the support 10 will change, and the new distance becomes s1. This new distance s1 is obviously different from the initial distance s. This change allows 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.

[0045] In the embodiment of the utility model, the stylus is composed of the support member, the touch sensor, the elastic member and the shell, the touch sensor is arranged around the support member, the elastic member is arranged between the shell and the touch sensor, the elastic member can generate deformation along the radial direction of the shell and / or the support member when being pressed by the shell and the touch sensor, in addition, the support member is provided with a gap, the touch sensor at least partially covers the gap, the gap is used for providing the touch sensor generating deformation with a clearance when the touch sensor is deformed by external force. The utility model provides the clearance on the support member to provide the touch sensor generating deformation with a clearance, thereby realizing the triggering of the touch sensor by external force, making the stylus more easily detect the distance change between the conductive object and the touch sensor under the action of external force, improving the detection precision and sensitivity of the touch sensor, in addition, the utility model also sets up the elastic member, the purpose of absorbing the assembly gap between the touch sensor and the shell is achieved, the outer wall of the touch sensor is tightly combined with the inner wall of the shell, and the detection precision and sensitivity are further improved.

[0046] Optionally, referring to Figure 2 and Figure 3 , Figure 3 is Figure 2 The stylus cross-section enlarged schematic view, the support member 10 includes: a plurality of convex structures 12 are arranged on the outer wall of the support member 10;Further referring to Figure 4 , Figure 4 is Figure 2 The appearance structure schematic view of the support member in it, the convex structure 12 is strip structure, the length extension direction of the convex structure 12 is consistent with the axial direction z of the support member 10, a plurality of convex structures 12 are arranged at intervals;The space formed between adjacent convex structures 12 constitutes a gap A.

[0047] In the first embodiment of the utility model, referring to Figure 2 and Figure 3 , the convex structure 12 can be arranged on the outer wall of the support member 10, the gap A can be formed between adjacent convex structures 12, when the conductive object does not touch the shell 40, the initial distance between the touch sensor 20 and the internal support member 10 is kept as s, the touch sensor 20 remains stationary, so there is no change in capacitance. When the conductive object touches the position corresponding to the gap A in the shell 40, the external pressure generated by the conductive object will be conducted to the inner touch sensor 20 by the elastic member 30, so that the touch sensor 20 generates deformation in the direction y, and the gap A provides the touch sensor 20 generating deformation with a clearance. At this time, the distance between the touch sensor 20 and the support member 10 will change, and the new distance becomes s2. The new distance s2 is obviously different from the initial distance s. This change makes the touch sensor 20 more easily sense the change of the corresponding capacitance and convert it into an electrical signal to realize accurate detection of touch.

[0048] It should be noted that the convex structure can be an integral structure with the support, and the convex structure can also be a separate structure with the support. The convex structure can be a non-elastic material. In an implementation, the convex structure can be a hard glue material. The convex structure can be prepared on the outer wall of the support by printing or the like. The convex structure can be an integral strip structure, or can be composed of a plurality of convex point structures arranged in a strip shape to form the convex structure. The embodiments of the present application do not limit this.

[0049] In addition, the surface of the convex structure in contact with the inner wall of the touch sensor can be provided as an outer arc surface, so that the surface of the convex structure in contact with the inner wall of the touch sensor can be closely contacted and fitted with the arc-shaped inner wall of the touch sensor. The opposite sides of the convex structure can also be rounded, which can reduce the damage of the edges of the convex structure to the inner wall of the touch sensor. The cross-sectional shape of the convex structure can also be trapezoidal, and the cross-sectional width of the convex structure uniformly increases in the direction of the support radially inward.

[0050] Optionally, the convex structure accounts for no more than 50% on the circular ring.

[0051] In the embodiments of the present application, referring to Figure 2 and Figure 3 , the circular ring is jointly formed by the gap A and the convex structure 12. The embodiments of the present application can set that the area ratio of the convex structure on the circular ring is not more than 50%. The purpose of this is that the support 10 can support the touch sensor 20 to maintain a good tension, and the area ratio of the gap A is as large as possible, so that the detection of the touch sensor 20 is more accurate and sensitive.

[0052] Optionally, referring to Figure 5 , Figure 5 is Figure 1 the appearance diagram of the support of the second embodiment of the stylus, and the surface of the support 10 is hollow to form a gap A.

[0053] In the second embodiment of the stylus provided by the present application, the gap A can be hollow on the surface of the support 10, that is, the gap A can be provided by the hollow through hole on the surface of the support 10. In this design, the support 10 provides support for the touch sensor 20 through the fixed part itself on one hand, and provides a space for the touch sensor 20 to deform on the other hand through the gap A formed by the hollow surface of the support 10. The fixed part is the part of the support 10 except the gap A, and the function of the fixed part is to support the inner wall of the touch sensor.

[0054] Preferably, referring to Figure 5 , the gap A can be a rectangular hole, and the long side direction of the gap A is consistent with the axial direction z of the support 10.

[0055] When the conductive object does not touch the shell 40, the initial distance between the touch sensor 20 and the support 10 inside remains s. When the conductive object touches the position corresponding to the gap A in the shell 40, the external pressure generated by the conductive object is conducted to the touch sensor 20 in the inner layer by the elastic member 30, so that the touch sensor 20 generates deformation in the direction y, and the gap A formed in the support 10 is used to provide a space for the touch sensor 20 to be deformed, at this time, the distance between the touch sensor 20 and the support 10 changes, and the new distance becomes s2. The new distance s2 is obviously different from the initial distance s. This change enables the touch sensor 20 to more easily sense the change of the corresponding capacitance and convert it into an electrical signal to achieve accurate detection of touch.

[0056] Optionally, referring to Figure 5 On the circumference where the gap A is located, the area occupied by the gap A is greater than 2:1 than the area occupied by the fixed part of the support 10.

[0057] Wherein, the circumference where the gap A is located is the circumferential surface formed by the outer surface of the support 10, and in the embodiment of the utility model, the area occupied by the gap A can be greater than 2:1 than the area occupied by the fixed part of the support 10 on the circumference where the gap A is located. The purpose of this is to make the area of the gap A as large as possible on the premise that the support 10 can support the touch sensor 20 to maintain a good tension, so that the detection of the touch sensor 20 is more accurate and sensitive.

[0058] Specifically, on the premise of meeting the basic supporting capacity of the support to maintain a good tension of the touch sensor 20, the area occupied by the fixed part of the support needs to be as small as possible, and preferably, the area occupied by the fixed part of the support is less than or equal to 10%.

[0059] It should be noted that the above gap A can be a rectangular hole, a circular hole, a trapezoidal hole or a hole of other shapes, and the present application does not limit this.

[0060] Optionally, referring to Figure 6 , Figure 6 is Figure 1 The appearance schematic view of the support of the third embodiment of the stylus, the support 10 is hollowed to form a gap, and at least part of the first gap A1 in all gaps is further provided with an auxiliary structure 11 that is elastically deformed when subjected to external pressure Figure 6 In the support 10, all gaps are first gaps A1 provided with the auxiliary structure 11, and the touch sensor 20 at least partially covers the auxiliary structure 11.

[0061] Specifically, in the third embodiment of the stylus, the auxiliary structure 11 can be arranged in the first gap A1 of the support 10, and the auxiliary structure 11 can be elastically deformed when extruded by an external force. The purpose of this is to increase the auxiliary structure 11 in the first gap A1 to provide a certain supporting effect on the inner wall of the touch sensor 20. In this way, the problem of poor supporting effect of the support 10 caused by the too large first gap A1 can be solved. In addition, through the elastic deformation of the auxiliary structure 11 itself, the deformation of the touch sensor 20 can be avoided, and the high-precision triggering of the touch sensor 20 can be realized. Wherein, referring to Figure 7 , which shows Figure 1 the cross-sectional view of the third embodiment of the stylus. The elastic deformation refers to the elastic deformation of the auxiliary structure 11 in the radial direction y of the shell 40 or the support 10 inward under the action of an external force. When the external force disappears, the elastic potential energy accumulated by the elastic deformation is released, so that the auxiliary structure 11 deforms and resets in the radial direction x of the shell 40 or the support 10 outward.

[0062] Preferably, referring to Figure 6 , the first gap A1 can be a rectangular hole, and the long side direction of the first gap A1 is consistent with the axial direction z of the support 10.

[0063] Optionally, referring to Figure 6 and Figure 7 , the auxiliary structure 11 includes: a resilient arm 111 arranged at the position of the first gap A1; the resilient arm 111 is elastically deformed when extruded by an external force; one end of the resilient arm 111 is connected with one side of the first gap A1, and the other end of the resilient arm 111 extends to the direction of the opposite side of the first gap A1.

[0064] Exemplarily, in Figure 6 and Figure 7 , the auxiliary structure 11 can specifically include a deformable resilient arm 111 structure. The resilient arm 111 is used for deforming in the radial direction y of the support 10 inward under the action of an external force, and deforming and resetting in the radial direction x of the support 10 outward when the action of the external force disappears.

[0065] In the embodiment of the utility model, the elastic arm 111 can be an integral structure with the support 10, and the elastic arm 111 is specifically a strip structure with one end extending from one side of the first gap A1 of the support 10 and the other end extending to the opposite side of the first gap A1. Since the other end of the elastic arm 111 is not connected with other structures, the elastic arm 111 can be deformed in the space formed by the first gap A1. When the conductive object touches the shell 10 of the stylus, the external force is transmitted from outside to inside, sequentially passes through the elastic member 30 and the touch sensor 20 and is conducted to the elastic arm 111, so that the elastic arm 111 is deformed and moves in the first gap A1 towards the radial direction y of the support 10. The movement of the elastic arm 111 can provide a space for the deformation of the touch sensor 20. In addition, when the external force disappears, the elastic arm 111 can be deformed and reset towards the radial direction x of the support 10. At this time, the elastic arm 111 can provide a supporting force for the inner wall of the touch sensor 20, thereby improving the supporting effect of the support 10 on the inner wall of the touch sensor 20.

[0066] Optionally, referring to Figure 6 , one first gap A1 is provided with two elastic arms 111; one end of one elastic arm 111 is connected with one side of the first gap A1, and one end of the other elastic arm 111 is connected with the opposite side of the first gap A1; the other ends of the two elastic arms 111 are spaced apart by a preset distance.

[0067] In the embodiment of the utility model, the first gap A1 is a rectangular through hole, and the regular structure of the first gap A1 is convenient for processing and implementation, and is also convenient for the symmetrical arrangement of the two elastic arms 111. In addition, the other ends of the two elastic arms 111 are spaced apart by a preset distance, so that the ends of the two elastic arms 111 are separated, and mutual collision of the ends of the two elastic arms 111 under stress is avoided.

[0068] Preferably, referring to Figure 6 , the two elastic arms 111 are arranged on two opposite short sides of the first gap A1.

[0069] In the embodiment of the utility model, the two elastic arms 111 are arranged on the two opposite short sides of the first gap A1, so that the length extension direction of the elastic arm 111 is consistent with the long side direction of the first gap A1. Compared with the scheme in which the elastic arm is arranged on the long side of the first gap A1 and the length extension direction of the elastic arm 111 is consistent with the short side direction of the first gap A1, the scheme in which the elastic arm 111 is arranged on the short side can set the length of the elastic arm 111 to be longer, so that the elastic arm 111 is more likely to be deformed under the action of external force, and the detection sensitivity of the touch sensor is further improved.

[0070] It should be noted that the elastic arm of the embodiment of the utility model can also be arranged at other positions of the first through hole, such as being arranged at the long side of the first gap, and the embodiment of the utility model does not limit this.

[0071] Optionally, referring to Figure 7 , the sum of the areas of the auxiliary structure 11 and the fixed part of the support 10 accounts for no more than 50% on the circular ring.

[0072] In the embodiment of the utility model, the circular ring is jointly constituted by the gap A, the auxiliary structure 1 and the fixed part of the support 10, the embodiment of the utility model can set that the area ratio of the sum of the areas of the auxiliary structure 11 and the fixed part of the support 10 on the circular ring is no more than 50%, and the purpose of this is to make the area ratio of the gap A as large as possible while maintaining sufficient tension of the touch sensor, so that the detection of the touch sensor 20 is more accurate and sensitive.

[0073] Optionally, referring to Figure 1 and Figure 5 , at least part of the second gaps A2 in all the gaps A are divided into multiple gap groups, and each gap group includes multiple second gaps A2 arranged in an array.

[0074] Optionally, referring to Figure 1 and Figure 5 , multiple second gaps A2 are arranged on the support 10; each group of second gaps A2 includes multiple second gaps A2 arranged in an array. Figure 1 In the embodiment of the utility model, two groups of second gaps A2 are arranged on the support 10, Figure 1 In the embodiment of the utility model, four groups of second gaps A2 are arranged on the support 10. Figure 1 and Figure 5 In the embodiment of the utility model, each group of second gaps A2 includes four second gaps A2 arranged in a 2x2 array; the multiple second gaps A2 included in each group of second gaps A2 are arranged in an array, which can uniformly distribute the second gaps A2 on the surface of the support 10, thereby realizing high-precision triggering of the touch sensor 20.

[0075] In the embodiment of the utility model, the first gap A1 refers to a gap in which the auxiliary structure 11 is arranged, and the second gap A2 refers to a gap in which the auxiliary structure 11 is not arranged.

[0076] Referring to Figure 1 , Figure 1 The appearance structure of the support 10 of the fourth embodiment of the stylus is shown, that is, on the support 10, both the first gap A1 with the auxiliary structure 11 and the second gap A2 without the auxiliary structure 11 are arranged, and each first gap A1 is arranged between two adjacent groups of second gaps A2.

[0077] In addition, the size of the first gap A1 is greater than the size of the second gap A2.

[0078] In the embodiment of the present application, the size of the first gap A1 can be set to be greater than the size of the second gap A2, and preferably, the size of the circumscribed rectangle of the whole composed of the plurality of second gaps A2 included in each group of second gaps A2 is set to be consistent with the size of the first gap A1.

[0079] In the embodiment of the present application, the stylus is composed of a support member, a touch sensor, an elastic member and a housing, the touch sensor is arranged around the support member, the elastic member is arranged between the housing and the touch sensor, the elastic member can generate deformation along the radial direction of the housing and / or the support member when being pressed by the housing and the touch sensor, in addition, the support member is provided with a gap, the touch sensor at least partially covers the gap, and the gap is used to provide a relief space for the touch sensor generating deformation when being pressed and deformed by external force. The present application provides a relief space for the touch sensor generating deformation by setting the gap on the support member, thereby realizing the triggering of the touch sensor by external force. Further, the present application further provides an auxiliary structure generating elastic deformation when being pressed by external force in the gap, so that the stylus based on the elastic deformation of the auxiliary structure is more likely to detect the distance change between the conductive object and the touch sensor under the action of external force, thereby improving the detection accuracy and sensitivity of the touch sensor.
