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.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0032] The utility model provides a gear switching device.

[0033] See also Figure 1-7 In one embodiment of the utility model, the gear switching device 100 includes: a bracket 1, a circuit board 2, a rotating frame and a conductive connecting member 4; the circuit board 2 is installed on the bracket 1, and the circuit board 2 is provided with a conductive area 221 and a plurality of gear areas 222; the rotating member 3 can be rotatably installed on one end of the bracket 1; the conductive connecting member 4 is fixedly installed on the rotating member 3, and the conductive connecting member 4 has a conductive body 41 and a first connecting arm 42 and a second connecting arm 43 connected to the conductive body 41. When the rotating member 3 rotates to a preset gear, the first connecting arm 42 is in contact with the conductive area 221, and the second connecting arm 43 is electrically connected to one of the gear areas 222.

[0034] In this embodiment, the bracket 1 is the support and installation structure of the entire gear switching device 100, and has multiple installation cavities for installing the electronic components of the stylus pen. The position of the electronic components is fixed, which can prevent the electronic components from shifting during use, resulting in poor contact of the circuit. The circuit board 2 is used to process circuit information to control the stylus to achieve different functions. The circuit board 2 has a conductive area 221 and a gear area 222 that are spaced apart. The conductive area 221 and each gear area 222 are insulated and non-conductive from each other. The conductive area 221 is connected to one of the gear areas 222 through a conductive connector 4 to form a current loop, thereby realizing the function of the corresponding gear, wherein the first connecting arm 42 of the conductive connector 4 is always in contact with the conductive area 221 to ensure the flow of current, and the second connecting arm 43 is connected to different gear areas 222 by rotation as needed, thereby realizing different functions. The rotating member 3 is used to be driven to rotate under the action of an external force. There is a mutually coordinated limiting structure between the rotating member 3 and the conductive connecting member 4, so that the conductive connecting member 4 can be driven to rotate synchronously with the rotating member 3. When the rotating member 3 rotates a certain angle, the conductive connecting member 4 can also be driven to rotate the same angle. When adjusting the gear position, the outside of the stylus pen has a corresponding gear position mark. When the indicator mark on the outside of the rotating member 3 is rotated to a position corresponding to the gear position mark, the internal conductive connecting member 4 will simultaneously connect the conductive area 221 and the corresponding gear area 222. The circuit board 2 processes the corresponding gear information according to the connected gear area 222 and converts it into an electrical signal, so that the stylus pen can realize the function of the gear position.

[0035] The technical solution of the utility model is to set a circuit board 2 in the gear switching device 100, and set a conductive area 221 and multiple gear areas 222 on the circuit board 2, so that the stylus has multiple adjustable gears; by setting a rotating member 3, and fixing the conductive connecting member 4 on the rotating member 3, the conductive connecting member 4 can rotate relative to the circuit board 2; by setting a first connecting arm 42 and a second connecting arm 43 that can abut against the circuit board 2 on the conductive connecting member 4, the conductive connecting member 4 can form a current loop with the circuit board 2; the first connecting arm 42 is always in abutment with the conductive area 221, and by rotating the conductive connecting member 4, the second connecting arm 43 can be made to abut against different gear areas 222 of the circuit board 2, thereby adjusting multiple different gears by rotation.

[0036] Reference Figure 2 In one embodiment, the bracket 1 includes a first mounting groove 11 and a second mounting groove 12 spaced apart along the axial direction of the stylus, and the second mounting groove 12 is arranged at one end of the bracket 1 close to the rotating member 3; the circuit board 2 includes a main body 21 and a conductive contact plate 22 electrically connected to the main body 21, the main body 21 is arranged in the first mounting groove 11, the conductive contact plate 22 and the conductive connecting member 4 are both arranged in the second mounting groove 12, the conductive contact plate 22 is located on a side of the conductive connecting member 4 close to the first mounting groove 11, and the conductive area 221 and the gear area 222 are arranged on a side of the conductive contact plate 22 close to the conductive connecting member 4. The bracket 1 includes two parts, namely a first bracket and a second bracket. The first mounting groove 11 is opened in the first bracket. The second bracket has a cavity open toward the first bracket. The second bracket is sleeved on one end of the first bracket close to the rotating member 3. The outer wall of the first bracket abuts against the inner wall of the cavity. When the first bracket is inserted into the cavity, the end of the first bracket is spaced apart from the bottom of the cavity, and the space between them forms a second cavity. The conductive connector 4 and the conductive contact pad 22 are arranged in the second cavity. The space of the second cavity enables the conductive connector 4 and the conductive contact pad 22 to always maintain a state of abutting each other. The end of the second bracket away from the first bracket is connected to the rotating member 3, and a through hole 121 is provided on the end face of the second bracket. The rotating shaft passes through the through hole 121 and is transmission-connected with the conductive connecting member 4. Since the end of the second bracket away from the first bracket is connected to the rotating member 3, the conductive connecting member 4 is arranged at the end of the second mounting groove 12 away from the first bracket, and the conductive contact plate 22 is arranged at the end of the second cavity close to the first bracket. The conductive area 221 and the gear area 222 are arranged on the side of the conductive contact plate 22 close to the conductive connecting member 4 to be electrically connected with the first connecting arm 42 and the second connecting arm 43 on the conductive connecting member 4.

[0037] In one embodiment, a through hole 121 is provided on a groove wall of a side of the second mounting groove 12 away from the first mounting groove 11; the rotating member 3 has a rotating shaft arranged along the axial direction of the bracket 1, the rotating shaft is passed through the through hole 121, a limiting protrusion 311 is provided at one end of the rotating shaft close to the bracket 1, a limiting through hole corresponding to the shape of the limiting protrusion 311 is provided in the middle of the conductive body 41, and the limiting protrusion 311 is passed through the limiting through hole. The shape of the protrusion at the end of the rotating shaft needs to be avoided to be set to a circle, otherwise the conductive connecting member 4 cannot be driven to rotate through the limiting through hole of the same size and shape, while the other shapes can be limited by the irregular shape edge to drive the conductive connecting member 4 to rotate. The through hole 121 is larger than the diameter of the rotating shaft to provide a channel for the rotating shaft to pass through without limiting the rotation of the rotating shaft; the size of the limiting protrusion 311 is smaller than the diameter of the rotating shaft to avoid the situation where the rotating shaft cannot pass through due to the limiting protrusion 311 being larger than the diameter of the through hole 121.

[0038] In one embodiment, the rotating member 3 further includes a fastener 32, which is inserted into the limiting protrusion 311, and the rotating member 3 is fixedly connected to the rotating shaft through the fastener 32. A threaded hole is provided in the center of the limiting protrusion 311 along the axial direction of the rotating shaft, and the fastener 32 is a screw, and the threaded section of the screw passes through the gasket 5 and the conductive body 41 in sequence and is threadedly connected to the threaded hole. The size of the screw nut is larger than the limiting through hole on the gasket 5 and the conductive body 41, so the conductive connector 4 and the gasket 5 can be limited between the screw nut and the end of the rotating shaft.

[0039] See also Figure 4 In one embodiment, the first connecting arm 42 and the second connecting arm 43 are bent and extended from the conductive body 41 toward the same side, and one end of the first connecting arm 42 and the second connecting arm 43 away from the conductive body 41 abuts against the conductive contact pad 22. In this embodiment, the first connecting arm 42 and the second connecting arm 43 are integrally arranged with the conductive body 41 to ensure the conductivity of the first connecting arm 42 and the second connecting arm 43 and the conductive body 41. The shapes of the first connecting arm 42 and the second connecting arm 43 are first cut out, and then the structures of the first connecting arm 42 and the second connecting arm 43 are formed by bending. In other embodiments, the first connecting arm 42 and the second connecting arm 43 can also be welded to the conductive body 41 by welding or other methods, which can save materials for manufacturing the conductive connector 4, thereby saving costs.

[0040] See also Figure 3 , 46. In one embodiment, the first connecting arm 42 has two elastic arms 44, which are arranged at intervals along the radial direction of the conductive body 41, one end of each elastic arm 44 is connected to the conductive body 41, and the other end has a contact portion 45 formed by bending toward the conductive body 41; and / or, the second connecting arm 43 has two elastic arms 44, which are arranged at intervals along the radial direction of the conductive body 41, one end of each elastic arm 44 is connected to the conductive body 41, and the other end has a contact portion 45 formed by bending toward the conductive body 41. The elastic arm 44 is elastic and can continuously contact the conductive contact pad 22 through the elastic potential energy generated by its own deformation. The provision of multiple elastic arms 44 can improve the adaptability of the first connecting arm 42 and the second connecting arm 43. The elastic arms 44 can be adjusted to different shapes and widths by bending and deformation to adapt to different sizes of conductive contact discs 22 and gear areas 222; when one of the elastic arms 44 is deformed in daily use, the other elastic arm 44 can still resist the conductive contact disc 22, which can improve the service life of the stylus. The end of each elastic arm 44 is bent upward to form a smooth arc, which prevents the conductive contact disc 22 from being worn and scratched due to the sharp end of the rotating member 3 during rotation, and also allows the elastic arm 44 to fit more closely with the conductive contact disc 22, with a larger contact area.

[0041] See also Figure 4 , 6 In one embodiment, the conductive area 221 is arranged in a ring shape, and a plurality of gear areas 222 are arranged at intervals on the outer periphery of the conductive area 221 along the rotation direction of the rotating member 3, and each gear area 222 corresponds to a gear function. By setting the conductive area 221 in a ring shape, the first connecting arm 42 can always be against the conductive area 221 no matter how much it rotates. The gear area 222 can be set according to the number of functions that need to be applied in the actual application of the stylus. By rotating the rotating member 3 and making the second connecting arm 43 stay on the corresponding gear area 222, the conductive area 221 and the corresponding gear area 222 can be connected, thereby realizing the function of the gear area 222.

[0042] In one embodiment, a light guide ring 13 is convexly provided on the outer wall of the bracket 1, and the light guide ring 13 abuts against one end of the rotating member 3 close to the bracket 1. The light guide ring 13 is used to provide visual feedback when the user uses the stylus pen, enhancing the user's perception and operating experience. Through the lighting or change of the light guide ring 13, the user can more intuitively understand the working status of the stylus pen, such as whether it is turned on, the battery status, the connection status, etc. The light guide ring 13 is surrounded by a light-guiding material so that the light emitted by the light-emitting element is evenly distributed on the light ring, forming a soft and uniform lighting effect.

[0043] In one embodiment, the gear switching device 100 further includes a gasket 5, which is disposed on a side of the conductive body 41 close to the circuit board 2. The gasket 5 is disposed between the conductive connector 4 and the nut of the screw, and is used to isolate the nut of the screw and the conductive connector 4, so as to prevent the nut and the conductive connector 4 from being worn and scratched during rotation, thereby protecting the conductive connector 4 and improving its service life.

[0044] The utility model also proposes a stylus pen 200, which includes a housing 20 and a gear switching device 100. The specific structure of the gear switching 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. In one embodiment, the gear switching device 200 is installed in the housing 20, and the housing 20 is used to protect the internal electronic components to prevent external dust and moisture from entering the internal electronic components and causing damage to the electronic components. The light guide ring 13 is added between the housing 20 and the rotating member 3 so that the user can identify the state of the stylus pen 200 through the light guide ring 13.
