[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. To provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; the following embodiments are part of the present invention; any other embodiments obtained based on this application without creative effort are within the scope of protection of the present invention.

[0021] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the clear description of the embodiments. They do not indicate or imply that the devices or components referred to must have a specific orientation and should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" in the embodiments are used solely for descriptive purposes and do not indicate or imply relative importance.

[0022] This utility model provides a lightweight flywheel encoder with switchable feel, aiming to achieve flexible switching of feel through a simple structural design while maintaining the lightweight characteristics of the device. The following is a detailed description of the specific implementation of this utility model.

[0023] like Figure 1-2 As shown, embodiment 1: a flywheel encoder with a lightweight and switchable feel based on a Hall sensor 7.

[0024] The flywheel encoder of this embodiment mainly consists of a bracket 1, an encoder module (including a Hall sensor 7), a roller 2, a tactile element 21, a magnetic ring 3 (trigger element), a key switch, and a tactile switching element 5. The tactile element 21 is an object that can provide a tactile feeling when the roller 2 is turned.

[0025] A hand-feeling member 21 is fixedly connected to the central axis of the roller 2. The hand-feeling member 21 is an annular structure with a bearing mounting seat 22 at the center. The bearing mounting seat 22 is connected to the inner ring wall of the roller 2 through reinforcing ribs 23. The reinforcing ribs 23 are distributed radially. Two high-precision bearings 25 are embedded in the bearing mounting seat 22. The bearings 25 are made of precision copper and have the characteristics of low friction and high speed, which can ensure that the roller 2 remains stable and smooth during rotation. Figure 5 As shown, the shaft 24 and the bearing 25 are tightly matched, and the shaft 24 is pivotally connected to the bracket 1. The shaft 24 is preferably made of stainless steel, and the bearing 25 and the shaft 24 are both of the common type of micro motors.

[0026] In this embodiment, the outer wall of the tactile element 21 is designed with toothed or wavy tactile projections to enhance operational feel. A push-button switch (self-locking switch 4) and a tactile switching element 5 are provided on the bracket 1. The self-locking switch 4 is positioned adjacent to the tactile switching element 5 and is mounted within a mounting slot in the bracket 1. A pivot post 12 is designed on the sidewall of the bracket 1, and a pivot hole 54 is designed in the middle of the tactile switching element 5, corresponding to the pivot post 12. The pivot hole 54 cooperates with the pivot post 12 to ensure the stability of the tactile switching element 5 during rotation.

[0027] The feel switching member 5 is a rigid frame with a connecting beam 51, a feel end 52, and a tilting end 53. The tilting end 53 abuts against the return spring 6 within the bracket 1. The bracket 1 is provided with a spring slot 11 for mounting the return spring 6. The pressure rod 41 of the self-locking switch 4 abuts against the tilting end 53. Pressing the self-locking switch 4 pushes the pressure rod 41 downward, pushing the feel end 53 away from the feel member 21. This changes the rotational damping of the roller 2 and achieves the feel switching.

[0028] The encoder module includes a flexible circuit board 8 and a Hall sensor 7. The magnetic ring 3 is nested between the hand-feeling part 21 and the bearing mounting seat 22 as a trigger element. The Hall sensor 7 is set corresponding to the magnetic ring 3. After the user adjusts the hand feel through the self-locking switch, the user rotates the roller 2. The rotation of the roller 2 drives the magnetic ring 3 to move. The change in the magnetic field of the magnetic ring 3 triggers the Hall sensor 7, generating an electrical signal. Figure 3 As shown (the outer wall protrusion of the hand-feeling part is not drawn in the figure), a toothed magnetic conductive sheet 26 is installed on the side of the hand-feeling part 21. The toothed magnetic conductive sheet 26 is a ring structure. A plurality of claws facing the Hall sensor 7 are evenly provided on the outer periphery of the ring structure of the toothed magnetic conductive sheet 26, which are used to guide or change the distribution of the magnetic field of the magnetic ring 3 to enhance the effect.

[0029] Embodiment 2: A flywheel encoder with a lightweight and switchable feel based on the optical tube assembly 10 .

[0030] like Figure 4As shown, the flywheel encoder of this embodiment differs primarily from that of the first embodiment in the encoder module and the triggering element. The encoder module of this embodiment comprises a flexible circuit board 8 and a light-pipe assembly 10 mounted thereon. The triggering element is a grating disk 9. The grating disk 9 is mounted on the end of the hand-feeling member 21 facing the light-pipe assembly 10. The grating disk 9 and the hand-feeling member 21 may be integrally formed. The grating disk 9 has multiple light-transmitting holes and opaque areas. When the roller 2 rotates, the grating disk 9 blocks or transmits light, thereby triggering the light-pipe assembly 10 to generate an electrical signal.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
