In the related art, in order to realize function switching of the stylus, a button is generally set in the radial direction of the stylus, and the function is switched by pressing. However, such a setting requires a larger radial size to give the button enough pressing stroke, and the radial size of the stylus becomes larger. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a stylus pen, which can trigger a switch by moving the pen core in the axial direction of the stylus pen, thereby reducing the radial size of the stylus pen.

[0004] The stylus pen according to the embodiment of the utility model includes a bracket, a circuit board assembly and a refill. The bracket is a hollow structure with openings at both ends; the circuit board assembly is arranged inside the bracket, and the circuit board assembly includes a switch; the refill is movably connected to the bracket, at least part of the refill is located inside the bracket, and the refill can move along the length direction of the bracket, so as to switch between a first position and a second position. When the refill is in the first position, the switch is not triggered by the refill, and the stylus pen is in the first function; when the refill is in the second position, the switch is triggered by the refill, and the stylus pen is in the second function.

[0005] The stylus pen according to the embodiment of the utility model has at least the following beneficial effects: the switch can be triggered or not triggered only by moving the pen core in the length direction of the bracket, thereby switching the stylus pen between the first function and the second function; there is no need to reserve a pressing stroke of a conventional button in the radial direction of the stylus pen, thereby reducing the radial size of the stylus pen and meeting the demand for a miniaturized stylus pen.

[0006] According to some embodiments of the present invention, the bracket and the pen core are both connected to the first elastic member, and the elastic force of the first elastic member is used to drive the pen core to move from the second position to the first position.

[0007] According to some embodiments of the utility model, one end of the bracket is a first opening, and the other end is a second opening. The stylus also includes a first elastic member, one end of the first elastic member abuts against the pen core and is away from the second opening, and the other end of the first elastic member is close to the second opening. The first elastic member is used to drive the pen core to move toward the first opening. In the initial state, the pen core is in the first position, and the pen core can be driven by the first external force to move from the first position to the third position. After the first external force is eliminated, the pen core is driven by the first elastic member to be fixed in the second position. The pen core can be driven by the second external force to move from the second position to the third position, and driven back to the first position by the first elastic member. The direction of the first external force and the second external force is the direction from the first opening to the second opening.

[0008] According to some embodiments of the utility model, the stylus pen further comprises a second elastic member, the pen core comprises an axis portion, a moving portion and a rotating portion, and the axis portion is fixedly connected to the moving portion.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0034] refer to Figures 1 to 3 According to the embodiment of the utility model, the stylus pen 100 includes a bracket 101, a circuit board assembly 103 and a refill 102. The bracket 101 is a hollow structure with openings at both ends; the circuit board assembly 103 is arranged inside the bracket 101, and the circuit board assembly 103 includes a switch 104; at least a part of the refill 102 is located inside the bracket 101, the refill 102 is movably connected to the bracket 101, and the refill 102 can move along the length direction of the bracket 101, so as to switch between a first position and a second position. When the refill 102 is in the first position, the switch 104 is not triggered by the refill 102, and the stylus pen 100 is in the first function. When the refill 102 is in the second position, the switch 104 is triggered by the refill 102, and the stylus pen 100 is in the second function. In this way, the switch 104 can be triggered or not triggered only by moving the pen core 102 in the length direction of the bracket 101, so that the stylus pen 100 can be switched between the first function and the second function. There is no need to reserve a pressing stroke of a conventional button in the radial direction of the stylus pen 100, thereby reducing the radial size of the stylus pen 100 and meeting the demand for a miniaturized stylus pen 100.

[0035] It should be noted that in some embodiments of the present invention, the first function of the stylus pen 100 is the writing function, and the second function of the stylus pen 100 is the erasing function. In some embodiments of the present invention, the first function and the second function can also be the switching of pen strokes of different thicknesses or the switching of different types of lines.

[0036] It should be noted that the switch 104 can switch the function of the stylus 100 mainly by using the triggering and non-triggering states of the switch 104 to send out two different preset output signals. Different output signals received on the touchpad correspondingly activate different functions.

[0037] refer to Figure 2 and Figure 3 In some embodiments of the utility model, the bracket 101 and the pen core 102 are both connected to the first elastic member 106, and the elastic force of the first elastic member 106 is used to drive the pen core 102 to move from the second position to the first position. Such a design can realize the use of the second function by applying an external force to the pen core 102 to move it to the second position, and then after the external force is eliminated, the elastic force of the first elastic member 106 is used to drive the pen core 102 to move toward the first opening 201 to realize the use of the first function, which simplifies the operation steps and improves convenience.

[0038] It should be noted that in the first position, the second position and the third position mentioned below in this specification, the pen core 102 gradually moves toward the second opening 202 .

[0039] It should be noted that the reference Figure 1 and Figure 2 In some embodiments of the present invention, the first elastic member 106 and the second elastic member 206 mentioned below are springs, and the springs are sleeved on the periphery of the pen core 102. Such a combined design can improve space utilization, make the internal structure of the stylus pen 100 more compact, and help reduce the size of the stylus pen 100 to meet the needs of a small stylus pen 100.

[0040] refer to Figures 2 to 5 and Fig. 9In some embodiments of the present invention, one end of the bracket 101 is a first opening 201, and the other end is a second opening 202. The stylus pen 100 further includes a first elastic member 106. One end of the first elastic member 106 abuts against the pen core 102 and is away from the second opening 202. The other end of the first elastic member 106 is close to the second opening 202. The first elastic member 106 is used to drive the pen core 102 to move toward the first opening 201. In the initial state, the pen core 102 is in the first position. The pen core 102 can be driven by the first external force to move from the first position to the third position. After the first external force is eliminated, the pen core 102 is driven by the first elastic member 106 to be fixed in the second position. The pen core 102 can be driven by the second external force to move from the second position to the third position, and driven back to the first position by the first elastic member 106. The directions of the first external force and the second external force are the directions from the first opening 201 to the second opening 202. With such a design, the function switching of the stylus pen 100 can be achieved by unidirectional pressing. Specifically, in the initial state, the pen core 102 is in the first position and the stylus 100 is in the first function. After applying the first external force, the pen core 102 can be driven by the first elastic member 106 to be fixed in the second position after moving to the third position. In this way, the stylus 100 can be in the second function without applying external force to maintain it. If you want to switch the stylus 100 to the first function, you only need to apply a second external force in the same direction as the first external force to press it. The pen core 102 can move from the second external position to the third position and then be driven by the first elastic member 106 back to the first position. The operation is simple and convenient.

[0041] refer to Figures 2 to 6 and Fig. 9In some embodiments of the present invention, the stylus pen 100 further includes a second elastic member 206, the pen core 102 includes a shaft 205, a moving part 203 and a rotating part 204, and the shaft 205 is fixedly connected to the moving part 203. One end of the second elastic member 206 abuts against the moving part 203 and is away from the first opening 201, and the other end of the second elastic member 206 is close to the first opening 201, and the second elastic member 206 is used to drive the moving part 203 to move toward the second opening 202. The rebound force of the second elastic member 206 is less than the rebound force of the first elastic member 106. The bracket 101 includes a plurality of track parts 401 and a plurality of clamping parts 402, and the track parts 401 and the clamping parts 402 are alternately arranged along the inner circumference of the bracket 101. The moving part 203 is provided with a plurality of first protrusions 501, and the rotating part 204 is provided with a plurality of second protrusions 502, and the first protrusions 501 and the second protrusions 502 can move along the track part 401. When the pen core 102 is in the first position, the first protrusion 501 and the second protrusion 502 abut against each other in the track portion 401. The abutting surface of the first protrusion 501 is the first abutting surface 503, the abutting surface of the second protrusion 502 is the second abutting surface 504, the clamping portion 402 includes the third abutting surface 404, and the outlet of the track portion 401 includes the fourth abutting surface 403. The first abutting surface 503, the second abutting surface 504, the third abutting surface 404 and the fourth abutting surface 403 are all inclined relative to the axial direction and radial direction of the bracket 101. When the second abutting surface 504 leaves the track portion 401, the elastic force of the first elastic member 106 drives the second abutting surface 504 to slide on the third abutting surface 404, so that the rotating portion 204 rotates to move toward the first opening 201 and is fixed on the clamping portion 402. At this time, the pen core 102 is in the second position; when the second abutting surface 504 leaves the clamping portion 402, the elastic force of the first elastic member 106 drives the second abutting surface 504 to slide on the fourth abutting surface 403, so that the rotating portion 204 rotates to move toward the first opening 201 and is fixed on the next track portion 401. At this time, the pen core 102 is in the first position.

[0042] Specifically, the process of the pen core 102 moving from the first position to the second position is as follows: Figures 2 to 5 and Fig. 9When the pen core 102 is in the first position, the first protrusion 501 and the second protrusion 502 abut against each other in the track portion 401, and the track portion 401 can well limit the movement direction of the moving portion 203 and the rotating portion 204. When the rotating portion 204 is in the track portion 401, it can only move along the track direction of the track portion 401. At this time, the first external force is applied, and the moving portion 203 pushes the rotating portion 204 to move in the direction of the second opening 202 until the second abutting surface 504 leaves the track portion 401. The radial constraint force of the rotating part 204 on the bracket 101 by the two side walls disappears, and the first external force is stopped, while the rotating part 204 is always subjected to the rebound force of the first elastic member 106. After the radial constraint force and the first external force disappear, the rotating part 204 is supported by the rebound force of the first elastic member 106 to move toward the first opening 201. When the second abutting surface 504 abuts against the third abutting surface 404 of the clamping part 402, the second abutting surface 504 slides along the third abutting surface 404, that is, the second protrusion 502 slides to Figure 5 The clamping portion 402, the resisting force of the inner wall surface of the clamping portion 402 and the rebound force of the first elastic member 106 are mutually balanced forces, so that the rotating portion 204 is fixed in the clamping portion 402. At this time, the moving portion 203 and the shaft portion 205 lose the restraint of the rebound force of the first elastic member 106, and are squeezed toward the second opening 202 by the rebound force of the second elastic member 206. At this point, the entire pen core 102 is fixed in the second position, the switch 104 is triggered, and the stylus 100 is in the second function.

[0043] Specifically, the process of the pen core 102 moving from the second position to the first position is as follows: Figures 2 to 6 as well as Fig. 9 When the refill 102 is in the second position, the rotating part 204 is held in the clamping part 402 by the first elastic member 106, and the moving part 203 and the shaft part 205 are held by the second elastic member 206. At this time, the second external force is applied, and the moving part 203 again abuts against the rotating part 204, so that the rotating part 204 moves toward the second opening 202. When the second abutting surface 504 leaves the clamping part 402, the restraining force of the inner wall of the clamping part 402 on the rotating part 204 in the radial direction of the bracket 101 disappears, and the application of the second external force stops. The rotating portion 204 is always subject to the rebound force of the first elastic member 106. After the radial constraint force and the second external force disappear, because the rebound force of the second elastic member 206 is smaller than the rebound force of the first elastic member 106, the rotating portion 204 is supported by the rebound force of the first elastic member 106 to move toward the second opening 202. When the second abutting surface 504 abuts against the fourth abutting surface 403 of the next track portion 401, the second abutting surface 504 slides along the fourth abutting surface 403, that is, the second protrusion 502 slides to Figure 5 As shown in the track portion 401 , until it returns to the first position, the switch 104 is not triggered and the stylus pen 100 is in the first function.

[0044] In this way, the conversion of the pen core 102 between the first position and the second position becomes simple and convenient, and only a one-way pressing operation is required, thereby facilitating the switching of the functions of the stylus pen 100 .

[0045] It should be noted that in some embodiments of the present invention, the second rebound member is not provided, and the rotating portion 204 and the shaft portion 205 are fixedly connected, so that when the rotating portion 204 is fixed in the clamping portion 402, the position of the shaft portion 205 is also fixed in the second position, and the same technical effect of the switching function can be achieved.

[0046] It should be noted that in some embodiments of the present invention, other types of unidirectional tracks may also be used. For example, the surface that needs to move is set as an inclined surface that is inclined inwardly relative to the axial direction of the stylus 100, and the blocking surface that is perpendicular to the axial direction of the stylus 100 is set in the direction where the movement needs to be restricted, thereby limiting the unidirectional movement of internal components and achieving the same technical effect.

[0047] In some embodiments of the present invention, the inclination angles of any two of the first abutting surface 503, the second abutting surface 504, the third abutting surface 404, and the fourth abutting surface 403 are equal. The inclination angle refers to the inclination angle of the abutting surface relative to the radial direction of the stylus 100. The equal inclination angle can make the angle between any two abutting surfaces as small as possible, so that relative sliding can occur smoothly and unnecessary friction can be reduced.

[0048] refer to Figure 8 and Fig.10 In some embodiments of the present invention, the stylus pen 100 further includes a pen tip 802, and the bracket 101 includes an elastic section 801. The elastic section 801 is elastic. When the pen tip 802 is inserted into the elastic section 801, the elastic force of the elastic section 801 presses the inner wall surface of the elastic section 801 against the outer peripheral surface of the pen tip 802 to limit the axial movement of the pen tip 802 relative to the elastic section 801. In this way, the pen tip 802 of the stylus pen 100 can be prevented from accidentally falling off or loosening during use. Moreover, the use of elastic force to press is more environmentally friendly and convenient than conventional glue bonding. Moreover, since the elastic section 801 is elastic, when the pen tip 802 is inserted into the elastic section 801 and assembled to the bracket 101, the assembly operation is convenient.

[0049] It should be noted that the reference Figure 8 and Fig.10 In some embodiments of the present invention, the stylus pen further includes a pen housing 803 , the bracket 101 is located inside the pen housing 803 , the pen housing 803 is provided with a through hole 805 , and the pen tip 802 passes through the through hole 805 and is partially exposed outside the pen housing 803 .

[0050] refer to Figure 8In some embodiments of the present invention, the elastic section 801 can extend from the second opening 202 in a direction away from the first opening 201. The elastic section 801 includes at least two clamping parts 804, which are spaced along the outer circumference of the pen tip 802 and surround the pen tip 802 together. The inner diameter of the track defined by the two clamping parts 804 gradually decreases in a direction away from the bracket 101. On the one hand, since at least two clamping parts 804 are spaced along the outer circumference of the pen tip 802, there is a gap between each clamping part 804. When the pen tip 802 is assembled to the bracket 101, space is provided for the elastic deformation of the elastic section 801, which is convenient for assembly; on the other hand, the design of gradually decreasing inner diameter can also make greater use of the resilience of the elastic member, so that the connection between the pen tip 802 and the elastic section 801 is more secure.

[0051] In some embodiments of the present invention, the switch 104 is a contact switch 104. The contact switch 104 conducts current through the contact between the metal sheet and the contact point, so the electronic response speed is fast and the response is sensitive. The switch can better realize the switching of functions in the embodiments of the present invention.

[0052] refer to Figure 7In some embodiments of the present utility model, the switch 104 includes a movable portion 602, a movable contact 605, a body portion 601, a fixed contact 604 and a third elastic member 603, the movable contact 605 is connected to the movable portion 602, the fixed contact 604 is connected to the body portion 601, and the third elastic member 603 is connected to the movable portion 602. When the pen core 102 is in the first position, at least a portion of the movable portion 602 is exposed outside the body portion 601, the movable contact 605 and the fixed contact 604 are arranged at intervals from each other, and at least a portion of the projection of the pen core 102 in its own axial direction falls on the exposed portion of the movable portion 602. When the pen core 102 is in the second position, the pen core 102 abuts against the movable part 602, at least a part of the movable part 602 is located in the body 601, and the movable contact 605 abuts against the fixed contact 604. When the abutment between the pen core 102 and the movable part 602 is released, the elastic force of the third elastic member 603 is used to drive the movable part 602 to extend outward relative to the body 601. When the movable contact 605 and the fixed contact 604 are arranged at intervals, the switch 104 is not triggered, and the stylus 100 is in the first function. When the pen core 102 moves from the first position to the second position, the end surface of the pen core 102 close to the second opening 202 abuts against the movable part 602 and pushes the movable part 602 to rotate, so that the movable contact 605 approaches the fixed contact 604. When the pen core 102 is in the second position, the movable contact 605 contacts the fixed contact 604, the switch 104 is triggered, and the stylus 100 is in the second function. When the refill 102 moves from the second position to the first position, the movable portion 602 is driven by the elastic force of the third elastic member 603 to extend outward relative to the main body 601, the movable contact 605 and the fixed contact 604 are disconnected, the switch 104 is not triggered, and the stylus 100 is in the first function. This arrangement can well combine the state of the switch 104 with the state of the refill 102, and the contact design also makes the state and function switching sensitive.

[0053] It should be noted that, in some embodiments of the present invention, the third elastic member 603 uses a torsion spring, which has a compact structure and a small size and can well realize the rotational reset of the movable part 602 .
