[0028] The utility model provides a gear adjustment device 100 .

[0029] See also Figure 1-4In one embodiment of the utility model, the gear adjustment device 100 is used for a stylus pen 200, comprising: a fixed seat 1, a rotating member 2 and an elastic member 3; the fixed seat 1 has an elastic member mounting position 11; the rotating member 2 can be rotatably sleeved on the outer side of the fixed seat 1, and the inner wall of the rotating member 2 is provided with at least two gear grooves 211 along the rotation direction; the elastic member 3 is installed at the elastic member mounting position 11, and the elastic member 3 is provided with an elastic limiting portion 31, and when the rotating member 2 rotates to a preset gear position, the elastic limiting portion 31 can be selectively inserted into the gear groove 211.

[0030] In this embodiment, the fixing seat 1 is the base of the gear adjustment device 100. As the basic part of the whole device, the fixing seat 1 and the stylus do not rotate. The top surface of the fixing seat 1 is provided with an elastic member installation position 11. The shape of the elastic member installation position 11 matches the shape of the elastic member 3 so that the elastic member 3 can be stably installed therein. The elastic member installation position 11 can be set to be open, which is convenient for disassembly and replacement when the elastic member 3 loses elasticity or deforms. It can also be set to be closed at the top, so that the elastic member 3 is not easy to fall out, and the stability of the structure of the elastic member installation position 11 is increased. The rotating member 2 is provided with a gear slot 211 inside, and the number of the gear slots 211 can be set according to the actual function of the final product. After the fixing seat 1 is fixedly connected to the stylus pen body, the elastic member 3 is installed in the elastic member installation position 11, and then the rotating member 2 is sleeved on the outside of the rotating shaft, and the elastic limiting portion 31 of the elastic member 3 is set within the range of the gear slot 211 on the inner wall of the rotating member 2. During the gear adjustment process, the rotating member 2 can only rotate within the range of multiple gear slots 211, and cannot exceed the range of the gear slot 211. The elastic member 3 switches from one gear slot 211 to another gear slot 211 through its own elasticity and elasticity; when the rotating member 2 is rotated, the elastic member 3 gradually contracts radially under the blocking effect of the slot wall of the gear slot 211, so that the elastic limiting portion 31 of the elastic member 3 can pass through the slot wall of the gear slot 211 along the circumferential direction. After passing through the slot wall, the elastic member 3 loses the blocking effect of the slot wall, and then automatically pops outward under the elastic effect, and is stuck in the next gear slot 211 to achieve the gear switching.

[0031] The technical solution of the present utility model is to set a fixed seat 1 with an elastic member installation position 11 in the gear adjustment device 100, set the elastic member 3 in the elastic member installation position 11, and rotatably sleeve the rotating member 2 with a gear groove 211 on the inner wall on the outer side of the fixed seat 1. The elastic member 3 has an elastic limiting portion 31, so that the elastic member 3 can be partially inserted into the gear groove 211 and limited, and the gear switching is achieved through the elastic expansion and contraction of the elastic member 3 and the rotation of the rotating member 2. The elasticity of the elastic member 3 in the technical solution of the present utility model can provide a clear touch and sound for the gear adjustment, so that the user can clearly feel whether the stylus 200 has been adjusted to the correct gear; the gear groove 211 also has a limiting function, which can limit the elastic limiting portion 31 on the elastic member 3 in the groove to avoid the situation where the gear is not adjusted properly due to the gear offset.

[0032] In one embodiment, a connection portion 12 for connecting to the body of the stylus pen is provided at one end of the fixing seat 1, and a boss 13 is provided at the other end. A through hole for the rotation axis to pass through is provided at the end surface of the boss 13 away from the connection portion 12, and an elastic member 3 is arranged around the periphery of the through hole; the rotating member 2 has a mounting cavity 22 open to the fixing seat 1, and a through hole for the rotation axis to pass through is provided at the end of the rotating member 2 away from the opening, and the boss 13 is arranged in the mounting cavity 22, and the rotating member 2 can rotate around the rotation axis and the boss 13. The connection portion 12 is provided with a connection structure such as a buckle, which is used to be fixedly connected to the body 30 of the stylus pen 200, and a component such as a colloid or an elastic body is filled between the connection portion 12 and the body 30 of the stylus pen 200 to be sealed and connected to the body 30. The boss 13 is arranged in a truncated cone shape to facilitate the rotation of the rotating body outside the fixing seat 1, and a through hole is provided in the middle of the boss 13 for passing the rotation axis. A limiting hole coaxially arranged with the through hole is provided on the rotating member 2, so that the rotating shaft can pass through the through hole and the limiting hole at the same time. The diameter of the limiting hole is slightly larger than the outer diameter of the rotating shaft, ensuring that the rotating member 2 always rotates around the rotating axis without deviation, thereby ensuring that the elastic member 3 can always be stuck in the limiting groove.

[0033] In one embodiment, the elastic member mounting position 11 is provided with a clamping portion 111, and clamping grooves 112 are respectively provided on both sides of the clamping portion 111. The elastic member 3 includes an elastic body 32 arranged in an arc shape, and the elastic body 32 is arranged around the outer periphery of the clamping portion 111. Both ends of the elastic body 32 are provided with bending portions 33 bent toward the clamping portion 111. The two bending portions 33 are clamped in the clamping grooves 112 one by one, and the middle section of the elastic body 32 protrudes toward the side away from the clamping portion 111 to form an elastic limiting portion 31. The clamping part 111 is a boss 13 protruding from the elastic member installation position 11. A through hole for the rotation shaft to pass through is provided in the center of the clamping part 111. The elastic member 3 is arranged around the outer periphery of the clamping part 111. The clamping groove 112 of the clamping part 111 is used to clamp the end of the elastic member 3 to limit the end of the elastic member 3. The elastic member 3 is a metal component formed by bending a long strip of metal. The cross section of the long strip of metal can be square or circular. The metal is curled along the elastic member installation position 11 to form an arc shape. Both ends are bent radially to form a bending part 33. A protrusion is pushed out radially outward in the middle of the arc to form an elastic limiting part 31. The shape of the protrusion is set to be a smooth semi-ellipse, which can make it easier for the elastic limiting part 31 to slide between the gear slots 211 for switching, and it is not easy to scratch the edge of the gear slot 211. The elastic member 3 has greater elasticity and hardness, so that when the gear is switched, it can trigger a greater touch, which is convenient for the user to perceive the gear.

[0034] In one embodiment, the elastic member installation position 11 is further provided with a first limiting portion 113 and a second limiting portion 114, the first limiting portion 113 and the second limiting portion 114 are respectively abutted against the ends of the two bending portions 33, and the first limiting portion 113 and the second limiting portion 114 are respectively provided with limiting grooves for accommodating the bending portions 33. The first limiting portion 113 has a first groove wall extending in the axial direction and a second groove wall extending from the first groove wall in the circumferential direction to form a certain distance, and the second limiting portion 114 has a third groove wall extending in the axial direction and a fourth groove wall extending from the third groove wall in the circumferential direction to form a certain distance; the second groove wall and the fourth groove wall extend in opposite directions. The shapes of the limiting portion and the bending portion 33 are adapted so that the bending portion 33 can completely fit in and abut against the limiting portion. When the elastic limiting portion 31 arranged in the middle of the elastic member 3 is subjected to radial pressure, the bending portions 33 at both ends of the elastic member 3 will not be displaced under the action of the first limiting portion 113 and the second limiting portion 114. At this time, the elastic member 3 is compressed and deformed under the action of the first limiting portion 113, the second limiting portion 114 and the external pressure. When the external pressure disappears, the elastic member 3 returns to its original shape. At this time, the bending portion 33 is always located at the first limiting portion 113 and the second limiting portion 114 and will not be offset.

[0035] In one embodiment, the elastic member installation position 11 is further provided with a third limiting portion 115, and the third limiting portion 115 has a first protrusion and a second protrusion arranged at intervals along the circumference of the elastic body 32, and the elastic limiting portion 31 is arranged between the first protrusion and the second protrusion, and the elastic limiting portion 31 protrudes from the outer surface of the third limiting portion 115. The first protrusion and the second protrusion are used to always limit the elastic limiting portion 31 on the elastic member 3 between the protrusions. When the external rotating member 2 rotates, the elastic limiting portion 31 will not swing with it, so that the elastic limiting portion 31 can be switched from one gear slot 211 to the next gear slot 211. The circumferential interval between the first protrusion and the second protrusion is the same as the width of the elastic limiting portion 31, and the radial height of the elastic limiting portion 31 is greater than the radial height of the first protrusion and the second protrusion. By setting the width of the elastic limiting portion 31 and the interval between the first protrusion and the second protrusion to be the same width, the elastic limiting portion 31 will not swing in the circumferential direction when it is arranged between the first protrusion and the second protrusion; the radial height of the elastic limiting portion 31 is greater than the height of the first protrusion and the second protrusion, and after the elastic limiting portion 31 is inserted into the first protrusion and the second protrusion, the elastic limiting portion 31 can pass through the first protrusion and the second protrusion to abut against the rotating member 2 and smoothly insert into the gear groove 211.

[0036] In one embodiment, the inner circumferential wall of the rotating member 2 is provided with a gear adjustment portion 21, and the gear adjustment portion 21 includes a plurality of convex ribs 212 convexly provided on the inner circumferential wall of the rotating member 2, and the plurality of convex ribs 212 are arranged at intervals along the circumference of the rotating member 2, and a gear groove 211 is formed between two adjacent convex ribs 212; when the rotating member 2 rotates to a preset gear, the top surfaces of the two convex ribs 212 located on both sides of the elastic limiting portion 31 respectively abut against the first protrusion and the second protrusion. The convex ribs 212 are used to divide the gear adjustment portion 21 into a plurality of required gears according to the actual use of the stylus 200, and the radial height of the convex ribs 212 cannot exceed the outer circumferential surface of the first protrusion and the second protrusion, otherwise the rotation of the rotating member will be restricted, and the height of the convex ribs 212 cannot be lower than the top surface of the elastic limiting portion 31, otherwise it cannot cooperate with the elastic member 3 to form an adjustable gear.

[0037] In one embodiment, the inner peripheral wall of the rotating member 2 is further provided with a limiting bone 213, and the limiting bone 213 is located outside the gear adjustment portion 21 in the circumferential direction of the rotating member 2; the radial height of the limiting bone 213 is greater than the radial height of the convex rib 212. Since the top surface of the convex rib 212 abuts against the outer peripheral surface of the first protrusion and the second protrusion, when the radial height of the limiting bone 213 is greater than the radial height of the convex rib 212, the limiting bone 213 will be blocked by the third limiting portion 115 and cannot rotate through the outer wall of the third limiting portion 115. When the rotating member 2 rotates, the third limiting portion 115 and the elastic limiting portion 31 provided in the third limiting portion 115 are always between the limiting bones 213. Therefore, the role of the limiting bone 213 is to limit the rotation range of the rotating member 2, ensure that the elastic limiting portion 31 always rotates in the gear adjustment portion 21, and will not cause the device to fail to achieve gear adjustment due to excessive adjustment.

[0038] In one embodiment, two limit bones 213 are arranged at intervals along the circumference of the rotating member 2, and the two limit bones 213 are arranged at intervals on both sides of the gear adjustment part 21. In this embodiment, in order to ensure that the rotating member 2 will not be over-adjusted regardless of whether it rotates clockwise or counterclockwise, the limit bones 213 are arranged at both ends of the gear adjustment part 21 to limit the rotation of the rotating member 2 in two directions. In other embodiments, when the gear adjustment part 21 has many gears and insufficient space, the limit bone 213 can also be arranged on only one side to prevent the rotating member 2 from over-rotating and improve space utilization.

[0039] In one embodiment, a mark 23 for identifying the gear position is provided on the outer wall of the rotating member 2. When the rotating member 2 rotates to a preset gear position, the mark 23 corresponds to the preset gear position mark on the pen body 30. The mark 23 can be a directional convex block convexly provided on the outer surface of the rotating member 2, or it can be concavely provided on the outer surface of the rotating member 2, or the mark 23 can be printed on the outer surface of the rotating member 2 by using different colors of paint.

[0040] The utility model also proposes a stylus pen 200, which includes a pen body 30, a pen cap 40 and a gear adjustment device 100. The specific structure of the gear adjustment device 100 refers to the above embodiment. Since the stylus pen 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. It includes: a pen body 30, a gear adjustment device 100 and a pen cap 40; the pen body 30 has a pen tip and a pen cap 40 end, and the pen cap 40 end has a rotating shaft; the gear adjustment device 100 is any of the above gear adjustment devices 100, the gear adjustment device 100 is fixedly connected to the pen cap 40 end, and the rotating shaft passes through the fixed seat 1 and the rotating member 2 at the same time; the pen cap 40 is arranged at the end of the gear adjustment device 100 away from the pen body 30, and the pen cap 40 is connected to the rotating shaft. The pen cap 40 is used to limit the axial movement of the rotating member 2, prevent the rotating member 2 from falling out during the gear adjustment process, and will not hinder the relative rotation between the rotating member 2 and the fixed seat 1. The rotating shaft can be made of threaded fasteners such as screws or bolts, and the pen cap 40 can be detachably connected to the rotating shaft by threading. The rotating shaft can also be set as a cylinder with a bayonet at the end, and a buckle is set on the pen cap 40. The pen cap 40 is pressed into the cylinder so that the buckle and the bayonet cooperate to achieve a detachable connection between the pen cap 40 and the rotating shaft. When using the stylus 200, the rotating member 2 is rotated, and the tactile feeling of the elastic member 3 being stuck in the gear slot 211, and the gear slot 211 having a certain limiting effect on the elastic member 3, the adjusted gear can be clearly perceived, and the problem of insufficient or excessive gear adjustment can be avoided.

[0041] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
