[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] The stylus can monitor the pressure change at the tip of the pen through the pressure enhancement component, thereby realizing the recognition of user input. When the stylus acts on the smart device, the tip of the pen can move along the axial direction of the pen shaft under the action of pressure, and the tip of the pen can interact with the elastic sheet during the movement to deform the elastic sheet. In the prior art, the elastic sheet of the pressure enhancement component is generally connected to a fixing member at one end and to a main bracket that can move relative to the fixing member at the other end. The main bracket is provided with a pen tip. When the pen tip contacts the smart device, it can push the main bracket to move relative to the fixing member, thereby causing the elastic sheet to deform. The sensor detects the deformation of the elastic sheet to obtain the force condition of the pen tip, thereby realizing the function of inputting and adjusting the thickness of lines in painting software, writing software, etc. Common stylus pressure detection sensors can be capacitive sensors, resistive sensors or shrapnel sensors. The prior art can detect the physical displacement or deformation generated after the pen tip is subjected to force, and convert it into an electrical signal output. In the prior art, the elastic sheet is only subjected to force in one direction of the main bracket, the deformation of the elastic sheet is small, the detection sensitivity of the pressure enhancement component is low, and the control accuracy is low, which makes it difficult to meet the user's needs for more precise control of fine lines and changes in brush strokes during painting and writing.

[0045] To solve the above technical problems, Figures 1 to 8 As shown, the present application proposes a pressure-sensitivity enhancement component 100 , which includes a base 110 , a main support 120 , a first elastic member 130 and a sensor 140 .

[0046] like Figure 1 , Figure 2 as well as Figure 3As shown, the base 110 has a shell 111 and a support portion 112. The shell 111 limits a receiving cavity 113. The support portion 112 is disposed in the receiving cavity 113 and connected to the shell 111. According to different requirements for the appearance design of the stylus, the shell 111 can be configured as a cylindrical shell 111. Specifically, the main bracket 120 can move relative to the shell 111 along the first direction X, and a projection surface is set perpendicular to the first direction X. The projection shape of the outer wall surface of the shell 111 on the projection surface along the first direction X can be a circle, a polygon, an ellipse, or a D-shaped or any other suitable shape. The inner wall surface of the shell 111 limits the receiving cavity 113, and the projection of the inner wall surface on the projection surface along the first direction X can also be a circle or any other suitable shape. The shape of the receiving cavity 113 can be set according to different installation requirements of the main bracket 120 provided with a pen tip.

[0047] like Figure 1 as well as Figure 2 As shown, the main bracket 120 is arranged in the accommodating cavity 113, and the main bracket 120 can move relative to the base 110 along the first direction X. That is to say, during use, relative to the main bracket 120, the base 110 serves as a fixed part, and the main bracket 120 serves as a movable part. The main bracket 120 may include a pen tip and a frame, etc. The main bracket 120 is arranged in the accommodating cavity 113, wherein the pen tip passes through the accommodating cavity 113 and can contact with the screen of a smart device, etc., thereby pushing the main bracket 120 to move relative to the base 110 along the first direction X.

[0048] like Figure 3 as well as Figure 4As shown, the first elastic member 130 includes a first connection portion 131 and a second connection portion 132, the first connection portion 131 intersects with the second connection portion 132, one end of the second connection portion 132 is connected to the main bracket 120, and the other end is connected to the first connection portion 131, the end of the first connection portion 131 away from the second connection portion 132 is connected to the main bracket 120, the first connection portion 131 is abutted or hinged with the support portion 112, when the main bracket 120 moves along the first direction X, the first connection portion 131 can rotate relative to the support portion 112, so that the end of the first connection portion 131 connected to the second connection portion 132 can move to the side away from the second connection portion 132. The first connection portion 131 can include a plate body, and can also include a plurality of plate bodies connected in sequence, and the support portion 112 can be abutted or hinged at any suitable position of the first connection portion 131. Taking the case where the support portion 112 abuts against the wall surface of the first connection portion 131 close to the second connection portion 132 as an example, driven by the main bracket 120, the first connection portion 131 can rotate around the support portion 112. It should be noted that, since the moving distance of the main bracket 120 is generally small, for the convenience of explanation, within this range, the rotation of the first connection portion 131 can be approximately equivalent to the end of the first connection portion 131 connected to the main bracket 120 moving along the first direction X, and the end of the first connection portion 131 connected to the second connection portion 132 moving in the direction opposite to the first direction X. The first connection portion 131 rotates around the support portion 112, that is, the end of the first connection portion 131 connected to the second connection portion 132 moves to the side away from the second connection portion 132, and the end of the second connection portion 132 connected to the main bracket 120 moves along the first direction X, thereby causing the two ends of the second connection portion 132 to be stretched in different directions. Since the overall displacement of the main bracket 120 is relatively small, for the sake of convenience, the movement of the two ends of the second connection part 132 can also be approximately equivalent to that when the end of the second connection part 132 connected to the main bracket 120 moves along the first direction X, the end of the second connection part 132 connected to the first connection part 131 moves in the direction opposite to the first direction X. In the technical solution of the present application, as long as the movement direction of the end of the first connection part 131 close to the second connection part 132 crosses the first direction X when the main bracket 120 moves along the first direction X so as to stretch the second connection part 132, the description here does not limit the displacement direction of the ends of the first connection part 131 and the second connection part 132.

[0049] like Figure 5As shown, the sensor 140 is attached to the second connection part 132, and the sensor 140 is used to detect the deformation of the second connection part 132. The sensor 140 is attached to the second connection part 132, and the sensor 140 is used to detect the deformation of the second connection part 132. The sensor 140 can be attached to the side of the second connection part 132 close to the main bracket 120, and can also be attached to the side of the first elastic sheet away from the main bracket 120. The contact surface between the sensor and the second connection part 132 can intersect with the first direction X, and preferably, the contact surface between the sensor and the first connection part 131 is perpendicular to the first direction X.

[0050] In the technical solution of the present application, the first connection part 131 and the second connection part 132 are arranged crosswise, and the first connection part 131 is abutted or hinged with the support part 112. When the main bracket 120 moves along the first direction X, the end of the first connection part 131 connected to the main bracket 120 moves along the first direction X together with the main bracket 120. Due to the arrangement of the support part 112, the end of the first connection part 131 close to the second connection part 132 can move to the side away from the second connection part 132. One end of the second connection part 132 is connected to the main bracket 120, and the other end is connected to the first connection part 131. When the main bracket 120 moves along the first direction X, the end of the second connection part 132 connected to the main bracket 120 moves along the first direction X, and the other end is stretched by the first connection part 131 in a direction intersecting with the first direction X. The sensor 140 is attached to the second connecting part 132. The second connecting part 132 can not only be deformed under the stretching of the main bracket 120, but also be deformed under the stretching of the first connecting part 131. The cooperation between the supporting part 112 and the first connecting part 131 amplifies the deformation of the second connecting part 132 caused by the displacement of the main bracket 120, and the input sensitivity and accuracy of the pressure enhancement component 100 are greatly improved.

[0051] To further improve the measurement accuracy of the pressure-sensing enhancement component 100, the deformation of the first elastic member 130 can be concentrated to the second connection portion 132. In some embodiments, the first connection portion 131 can be configured as a rigid component, and the second connection portion 132 can be configured as an elastic component. In some embodiments, both the first connection portion 131 and the second connection portion 132 can be configured as elastic components, wherein the elastic modulus of the first connection portion 131 is not less than the elastic modulus of the second connection portion 132. Figure 6As shown, in this embodiment, the first connecting portion 131 includes a first plate 1311, the first plate 1311 is connected to the end of the second connecting portion 132 away from the main bracket 120, the first plate 1311 has a first wall 1312 parallel to the first direction X, the second connecting portion 132 has a second wall 1321 intersecting the first wall 1312, the first plate 1311 has a first thickness a along a direction perpendicular to the first wall 1312, and the second connecting portion 132 has a second thickness b along a direction perpendicular to the second wall 1321, and the first thickness a and the second thickness b satisfy: a>b. Specifically, the first thickness a can be 1.2 times, 1.3 times, 1.5 times, 2 times, 3 times or any other suitable multiples of the second thickness b. The thickness of the first connecting portion 131 is not less than the thickness of the second connecting portion 132, so that the deformation of the first connecting portion 131 during the movement of the main bracket 120 is greatly reduced, and the deformation is further concentrated on the second connecting portion 132. It can be understood that the first wall surface 1312 intersects with the second wall surface 1321. Specifically, Figure 7 , Figure 8 as well as Figure 6 As shown, the angle between the first wall surface 1312 and the second wall surface 1321 can be an acute angle, an obtuse angle or a right angle. Figure 3 as well as Figure 8 As shown, when the angle between the first wall surface 1312 and the second wall surface 1321 is a right angle or an obtuse angle, in order to further amplify the deformation of the second connecting portion 132 , preferably, the first connecting portion 131 may also be provided with a second plate body 1313 .

[0052] The first connection portion 131 can rotate relative to the support portion 112 under the drive of the main bracket 120, so that the end of the first connection portion 131 connected to the second connection portion 132 can move away from the second connection portion 132. Figure 4 As shown, in some embodiments, the support portion 112 can be configured as a column, a rib plate or any suitable protrusion. In some embodiments, the support portion 112 can also be configured as a hole or a groove, and the first elastic member 130 is provided with a column hinged to the support portion 112. Specifically, the wall surface of the first connection portion 131 close to the second connection portion 132 can abut against the support portion 112, or the first connection portion 131 can be provided with a hinge end directly hinged to the support portion 112. When the first connection portion 131 is provided with different plates, the support portion 112 can also abut against the wall surface of the different plates of the first connection portion 131. Figure 6As shown, in some embodiments, the first connection portion 131 includes a first plate 1311, one end of the first plate 1311 is connected to the second connection portion 132, and the other end is connected to the main bracket 120, the support portion 112 abuts against a side of the first plate 1311 close to the second connection portion 132, the first wall 1312 is provided on a side of the first plate 1311 close to the second connection portion 132, and the support portion 112 abuts against the first wall 1312. Figure 6 As shown, in some embodiments, the first connection portion 131 further includes a second plate 1313, the second plate 1313 has a third wall 1314 parallel to the second wall 1321, the second plate 1313 is connected to an end of the first plate 1311 away from the second connection portion 132, and the support portion 112 abuts against the third wall 1314. In some embodiments, the support portion 112 may also be provided with a plurality of columns to abut against the first wall 1312 and the third wall 1314 respectively. Figure 6 As shown, in some embodiments, the support portion 112 can be disposed at the intersection of the first wall 1312 and the third wall 1314, so that the support portion 112 can abut against the first wall 1312 and the third wall 1314 at the same time. In some embodiments, the support portion 112 can also be hinged to the first plate 1311 or the second plate 1313, which will not be repeated here.

[0053] In order to further improve the rigidity of the first connection part 131 and further concentrate the deformation of the first elastic member 130 on the second connection part 132, in some embodiments, the strength of the first connection part 131 can be improved by increasing the thickness of the second plate 1313 along the first direction X and increasing the width of the second plate 1313 perpendicular to the first direction X, thereby reducing the deformation of the first connection part 131 during the movement of the main bracket 120. Figure 3 as well as Figure 5As shown, in some embodiments, the first connection portion 131 may also be provided with a reinforcing portion 1315, and the reinforcing portion 1315 may be used to increase the thickness of the first connection portion 131 along the first direction X, and the reinforcing portion may be used to increase the height of the first connection portion 131 along the second direction Y, and may also be used to increase the width of the first connection portion 131 along the third direction Z, which is not limited here. In this embodiment, the direction perpendicular to the first wall surface 1312 is the second direction Y, and the direction perpendicular to the first direction X and the second direction Y is the third direction Z. The first connection portion 131 also includes a reinforcing portion 1315, and the reinforcing portion 1315 is adjacent to the second plate body 1313 along the third direction Z. Among them, the reinforcing portion 1315 may be connected to the second plate body 1313 on one side, and abut against the support portion 112 on the other side. The reinforcing portion 1315 may also be connected to the second plate body 1313 on one side, and abut against the main bracket 120 on the other side. The reinforcing portion 1315 may be configured as a rib plate, an angle steel, a bracket or any other suitable component, which is not limited here. The reinforcing portion 1315 is connected to the second plate 1313 . The reinforcing portion 1315 abuts against the main bracket 120 or the base 110 to enhance the stability of the second plate 1313 during the movement of the main bracket 120 along the first direction X, while concentrating the deformation of the first elastic member 130 on the second connecting portion 132 .

[0054] In some embodiments, the reinforcing portion 1315 is connected to the second plate 1313, and the reinforcing portion 1315 increases the width of the first connecting portion 131 along the third direction Z at the second plate 1313. Preferably, the width of the first connecting portion 131 along the third direction Z may be greater than the width of the first connecting portion 131 along the third direction Z. Figure 5 As shown, in this embodiment, along the third direction Z, the sum of the widths of the reinforcing portion 1315 and the second plate body 1313 is the first width c, the second connecting portion 132 has a second width d, and the first width c and the second width d satisfy: c>d. Specifically, the first width c can be 1.2 times, 1.4 times, 1.5 times, 2 times, 3 times, 5 times, or any other suitable multiple of the second width d.

[0055] In order to improve the recognition stability of the pressure-sensing enhancement component 100, the connection between the first connection part 131 and the second connection part 132 may be provided with a first arc segment 1317, and the connection between the various plates of the first connection part 131 and the connection between the first connection part 131 and the main bracket 120 may also be provided with a first arc segment 1317. Figure 3As shown, in this embodiment, the second plate body 1313 has a straight plate segment 1316 and a first arc segment 1317, the straight plate segment 1316 is provided with a third wall surface 1314, the straight plate segment 1316 is connected to the first plate body 1311, one end of the first arc segment 1317 is connected to the side of the straight plate segment 1316 away from the first plate body 1311, and the other end is connected to the main bracket 120, and the center of the first arc segment 1317 is set at the side of the second plate body 1313 close to the second connecting portion 132. Firstly, the setting of the first arc segment 1317 can provide a smooth transition for the connection between the main bracket 120 and the first connecting portion 131. When the main bracket 120 is subjected to pressure, the springs of each segment can work more smoothly together, reducing the possibility of spring breakage and input jump, thereby improving the accuracy and stability of pressure sensing. Secondly, the setting of the first arc segment 1317 can optimize the pressure distribution on the first elastic part. The design of the first arc segment 1317 can more effectively disperse and transmit pressure, reduce the possibility of excessive stress concentration on the first elastic part, and thus extend the service life of the pressure enhancement component 100. In addition, the setting of the first arc segment 1317 can enhance the structural stability of the first elastic part, and the first arc segment 1317 and the main bracket 120 can support each other, thereby reducing the deformation or damage of the first elastic member 130 caused by sudden changes in external force. In other words, the setting of the first arc segment 1317 can also optimize pressure sensing and enhance structural stability, so that the pressure enhancement component 100 can provide the user with a more accurate and smooth input experience when in use, which helps to improve the user's satisfaction. In some embodiments, the second connecting portion 132 has a second arc segment 1322 on the side close to the first plate body 1311, and the second arc segment 1322 is connected to the first plate body 1311. The provision of the second arc segment 1322 can improve the connection stability between the first plate 1311 and the second connection portion 132, and reduce the risk of damage to the first elastic member 130. In some embodiments, the second plate 1313 has a third arc segment 1318 on one side close to the first plate 1311, and the third arc segment 1318 is connected to the first plate 1311. The provision of the third arc segment 1318 can improve the connection stability between the first plate 1311 and the second plate 1313, and reduce the risk of damage to the first elastic member 130, which will not be described in detail here.

[0056] The connection method between the support portion 112 and the first connection portion 131 may vary according to different design requirements. Specifically, the first support portion 112 may abut against the first connection portion 131, or the first support portion 112 may be hinged to the support portion 112, as long as the first support portion 112 can rotate relative to the first support portion 112. Figure 3As shown, in this embodiment, the support portion 112 is configured as a cylinder, the axis of the support portion 112 is perpendicular to the first direction X, the main bracket 120 limits a first through hole 121, the support portion 112 is penetrated in the first through hole 121 and abuts against the first connecting portion 131. Preferably, the axis of the support portion 112 can be parallel to the third direction Z, and the support portion 112 can penetrate the accommodating cavity 113 along the third direction Z, that is, both ends of the support portion 112 along the third direction Z can be connected to the shell 111, thereby improving the connection stability between the support portion 112 and the shell 111. It should be noted that the support portion 112 is penetrated in the first through hole 121, and in order to enable the main bracket 120 to move along the first direction X, a certain gap can be left between the support portion 112 and the first through hole 121, or the first through hole 121 can be set as a through groove extending along the first direction X, which is not limited here.

[0057] The main support 120 will move along the first direction X when subjected to external force. In order to reduce the impact force of the main support 120 on the first elastic sheet when subjected to impact, the pressure-sensing enhancement component 100 may be provided with a plurality of elastic members to assist the first elastic member 130 in guiding the movement of the main support 120, or to limit the movement of the main support 120 along the first direction X, thereby improving the deformation stability of the first elastic member 130 and reducing the risk of damage to the first elastic member 130. Figure 3As shown, in some embodiments, the pressure-sensing enhancement component 100 further includes a second elastic member 150, which is disposed on a side of the first connection portion 131 away from the second connection portion 132, and is connected to the base 110. The second elastic member 150 has a second through hole 151, and the main bracket 120 is passed through the second through hole 151 along the first direction X and abuts against the second elastic member 150. The second elastic member 150 can be welded to the housing 111, can be clamped to the housing 111, or can be integrally formed with the housing 111. The provision of the second elastic member 150 can reduce the impact of the main bracket 120 on the first elastic member 130 on the one hand, and can improve the movement accuracy of the main bracket 120 in the first direction X on the other hand. Specifically, in some embodiments, the second elastic member 150 may be provided with a plate extending along the first direction X and a plate extending along the second direction Y. The plate of the second elastic member 150 extending along the first direction X abuts against the main bracket 120 to further limit and guide the movement of the main bracket 120 in the first direction X. The plate of the second elastic member 150 extending along the second direction Y may be provided with a second through hole 151. The main bracket 120 is penetrated by the second through hole 151 so that the second elastic member 150 can limit the movement of the main bracket 120 in any other direction perpendicular to the first direction X, thereby improving the movement accuracy of the main bracket 120 along the first direction X and optimizing the detection accuracy of the sensor 140. It can be understood that the main bracket 120 can be provided with a guide groove extending along the first direction X, and the end of the second elastic member 150 close to the main bracket 120 can also be inserted into the guide groove. When the impact force applied to the main bracket 120 causes the moving stroke of the main bracket 120 to exceed the length of the guide groove, the second elastic member 150 can abut against the wall of the guide groove, thereby enabling the second elastic member 150 to limit the movement of the main bracket 120.

[0058] like Figure 2 as well as Figure 4As shown, in some embodiments, the pressure-sensing enhancement component 100 may also be provided with a third elastic member 160. The housing 111 may be provided with an opening communicating with the accommodating cavity 113. The pressure-sensing enhancement component 100 further includes a third elastic member 160, which is provided on a side of the first elastic portion close to the second elastic portion. One end of the main bracket 120 is passed through the opening, and the other end is in contact with the third elastic member 160. The third elastic member 160 is used to limit the movement of the main bracket 120 along the first direction X. The pressure-sensing enhancement component 100 may further include components such as a flexible circuit board. The main bracket 120 moves along the first direction X. When the main bracket 120 is impacted, not only the first elastic member 130 and the sensor 140 may be damaged, but also the flexible circuit board and the like provided in the accommodating cavity 113 may be damaged. In this embodiment, the pressure enhancement component 100 further includes a third elastic member 160, which is disposed on a side of the first connection portion 131 close to the second connection portion 132, one end of the third elastic member 160 is connected to the base 110, and the other end is connected to the main bracket 120, and the third elastic member 160 is used to limit the movement of the main bracket 120 along the first direction X. Specifically, the third elastic member 160 can be connected to the housing 111. The third elastic member 160 is disposed on a side of the first elastic portion close to the second elastic portion, and the third elastic member 160 partitions the accommodating cavity 113. The third elastic member 160 limits the main bracket 120 to a side of the third elastic member 160 close to the opening, and the third elastic member 160 can limit the movement of the main bracket 120 along the first direction X, thereby greatly reducing the risk of the main bracket 120 damaging the device on the side of the third elastic member 160 away from the opening. In some embodiments, the third elastic member 160 can be provided with a plate extending along the second direction Y, and can also be provided with a plate extending along the first direction X. In some embodiments, the third elastic member 160 can be integrally formed with the shell 111 to reduce the manufacturing cost and assembly difficulty of the pressure-sensing enhancement component 100, which will not be described in detail here. It is understandable that the third elastic member 160 can also be provided with an arc segment connected to the shell 111 so that the third elastic member 160 can be more stably connected to the shell 111 when impacted, so that the movement stroke of the main bracket 120 along the first direction X can be stably controlled. As shown in the figure and the figure, the shell 111 can be provided with a hole connected to the third elastic member 160, and the third elastic member 160 can be provided on the side of the hole provided in the shell 111 close to the opening, and can also be provided on the side of the hole provided in the shell 111 away from the opening.
