Please refer to Figure 1 to Figure 3. According to an embodiment, an input device 1 includes a device housing 12, a control module 14, a roller 16, an elastic hook 18 and an adjustment mechanism 20. The control module 14 (shown schematically in FIG. 2 with a dotted line) is disposed in the device housing 12. In practice, the control module 14 can be implemented by, but not limited to, a circuit board module (which can include a circuit board, a control chip disposed on the circuit board, other required electronic components and components, etc.), which It can sense the rotation of the scroll wheel 16 (for example, for scrolling input), the movement of the device housing 12 relative to the external environment (for example, for moving input), and communicate with an external device (for example, a computer host) (for example, via Cable 22) and other functions. The roller 16 is rotatably disposed in the device casing 12 and has a wheel portion 162 and a rotating shaft 164 fixedly connected to the wheel portion 162. The wheel portion 162 can rotate relative to the device casing 12 via the rotating shaft 164. The wheel 162 protrudes from the device housing 12 so that the user can rotate the roller 16 from the outside of the input device 1. The rotating shaft 164 has a peripheral surface 1642 and a plurality of tooth grooves 1644 on the peripheral surface 1642. The elastic hook 18 is disposed in the device housing 12 adjacent to the roller 16 and can be inserted into or separated from the plurality of tooth grooves 1644. The adjustment mechanism 20 is arranged in the device housing 12 and includes a linkage portion 202 and an operating portion 204. The linkage portion 202 is movably arranged and connected to the elastic hook 18, and the operating portion 204 is connected to the linkage portion 202 and exposed to the device housing 12. The operation part 204 can be operated by the user from outside the input device 1. Thereby, the user can operate the operating portion 204 to move the elastic hook 18 through the linkage portion 202 to disengage the elastic hook 18 from the plurality of tooth grooves 1644 or change the engagement between the elastic hook 18 and the plurality of tooth grooves 1644 Degree (including partial engagement, full engagement, and contact force).

In addition, in this embodiment, the device housing 12 includes a housing 122 and a roller support structure 124 disposed inside the housing 122. The control module 14, the roller 16, the elastic hook 18 and the adjustment mechanism 20 are also arranged inside the housing 122. The outer shell 122 includes an upper shell 1222 and a bottom shell 1224 that are connected to each other. The roller supporting structure 124 is fixed on the bottom shell 1224, such as but not limited to plastic injection molding. The roller support structure 124 supports the roller 16 via the rotating shaft 164. The operating portion 204 is rotatably connected to the bottom of the device housing 12; wherein, the operating portion 204 includes a screw 2042 and a retaining ring 2044. The screw 2042 rotatably penetrates the bottom housing 1224 (ie, the device housing 12) via the retaining ring 2044. The bottom) and exposed at the bottom shell 1224. The linkage portion 202 includes a carrier 2022 and a screw hole post (for example, but not limited to, implemented by a nut 2024). The nut 2024 is fixed to the carrier 2022 (for example, but not limited to, the carrier 2022 is embedded in the carrier 2022 through the nut 2024) and engaged with the screw 2042 , The elastic hook 18 is fixed to the carrier 2022. The adjustment mechanism 20 further includes a guide groove structure 206 fixed on the bottom shell 1224, such as but not limited to plastic injection molding. The carrier 2022 is slidably disposed in the guide groove structure 206. Thereby, the screw 2042 can be operated (for example, the user rotates the screw 2042 from the device housing 12) to rotate relative to a rotating shaft 204a (shown as a chain line in FIG. 2) so that the linkage portion 202 and the nut 2024 rotate together The shaft 204a moves relative to the screw 2042, so that the elastic hook 18 can move parallel to the rotating shaft 204a relative to the rotating shaft 164, thereby realizing that the elastic hook 18 is separated from the plurality of tooth grooves 1644 or the elastic hook 18 and the plurality of tooth grooves are changed The degree of meshing between 1644.

In practice, the head of the aforementioned screw 2042 can have an appropriate shape for the user to rotate with bare hands or with a tool; moreover, an indicator mark can also be provided on the bottom shell member 1224 to indicate the direction of rotation of the screw 2042 and the elastic hook 18 For the relation of meshing with the plurality of tooth grooves 1644, for example, clockwise rotation may tend to make the elastic hook 18 mesh with the plurality of tooth grooves 1644, and counterclockwise rotation may tend to cause the elastic hook 18 to disengage from the plurality of tooth grooves 1644. In addition, in practice, the retaining ring 2044 can be implemented by a retaining ring, a bearing, or other components that can allow the screw 2042 to rotate relative to the bottom housing 1224; or, if there is no concern about interference with the upper structure, the retaining ring can be omitted 2044, the screw 2042 directly engages with the screw hole of the bottom shell 1224, which can also allow the screw 2042 to rotate relative to the bottom shell 1224. In addition, the screw 2042 can provide the user with a stepless adjustment of the position of the elastic hook 18, but in practice, it can be implemented through indicator marks and a limit structure (for example, provided on the retaining ring 2044 to limit the rotation of the screw 2042). Angle) and other methods provide paragraph-style adjustment, so that users can quickly adjust.

In this embodiment, the elastic hook 18 includes a fixing portion 182, an elastic deformation portion 184, and a hook portion 186. The elastic deformation portion 184 connects the fixing portion 182 and the hook portion 186, and the elastic hook 18 passes through the fixing portion 182. Fixed on the carrier 2022 of the linkage portion 202, the elastic hook 18 hooks one of the plurality of tooth grooves 1644 via the hook portion 186. When the hook portion 186 is locked into the plurality of tooth grooves 1644, the elastic hook 18 is elastically deformed through the elastic deformation portion 184 to allow the rotating shaft 164 to rotate relative to the hook portion 186. In this embodiment, the elastic deformation portion 184 includes a curved portion (such as but not limited to the semicircular structure in the figure) to increase elasticity; however, in practice, it is not limited to this. For example, the elastic deformation portion 184 is implemented by a bending structure; for another example, the elastic deformation portion 184 or the elastic hook 18 is implemented by a spring. In addition, in this embodiment, the fixing portion 182 and the hooking portion 186 are approximately located on the same horizontal plane (perpendicular to the rotation axis 204a).

Please also refer to FIG. 4; wherein, the bottom shell 1224 is shown in cross section in FIG. 4. The user can operate the operating portion 204 (or the rotating screw 2042) to change the relative position of the elastic hook 18 with respect to the plurality of tooth grooves 1644 (or the rotating shaft 164). As shown in FIG. 4, when the elastic hook 18 moves to a first position P1 (shown in the figure with a dotted line), the hook portion 186 of the elastic hook 18 is separated from the plurality of tooth grooves 1644. At this time, the rotation resistance of the scroll wheel 16 is the smallest, which is suitable for quickly rotating the scroll wheel 16, for example, when a web page needs to be quickly scrolled. When the elastic hook 18 moves to a second position P2 (as shown by the solid line in the figure), when the hook portion 186 is partially engaged with the plurality of tooth grooves 1644 (for example, the elastic hook 18 partially extends into one of the teeth). Slot 1644). At this time, although the hooking portion 186 is not in close contact with the tooth grooves 1644, when the rotating shaft 164 rotates, the hooking portion 186 and the plurality of tooth grooves 1644 will cause structural interference, so the rotation resistance of the roller 16 is slightly increased. At this time, the input device 1 can provide the user with lighter tactile feedback, for example, it is suitable for young or elderly people to rotate the scroll wheel 16 in general use situations. In addition, as the degree of structural interference between the hook portion 186 and the plurality of tooth grooves 1644 increases (for example, the elastic hook 18 continues to move toward the rotating shaft 164), the rotation resistance of the roller 16 also increases, and the aforementioned tactile feedback is gradually obvious (making The wheel 16 turns more and more heavier).

When the elastic hook 18 moves to a third position P3 (shown in dotted lines in the figure), the hook portion 186 is completely engaged with the plurality of tooth grooves 1644 (for example, the elastic hook 18 is locked into one of the tooth grooves 1644 Inside), the hooking portion 186 is in principle tightly fitted with the tooth groove 1644. At this time, the rotation resistance of the roller 16 increases again, which can provide heavier tactile feedback, for example, it is suitable for general adults to rotate the roller 16 in general use situations. When the elastic hook 18 further moves to a fourth position P4 (shown in dotted lines in the figure), the hook portion 186 is completely meshed with the plurality of tooth grooves 1644 and the contact force increases (for example, the elastic hook 18 is stressed The ground is locked into one of the tooth grooves 1644), and the elastic deformation portion 184 is elastically deformed. At this time, the rotation resistance of the roller 16 increases again, which can provide heavier tactile feedback. In addition, as the degree of elastic deformation of the elastic deformation portion 184 increases (for example, the elastic hook 18 continues to move toward the rotating shaft 164), the rotation resistance of the roller 16 and the contact force also increase. In this way, the contact force can be adjusted to provide different tactile feedback, which can increase the diversity of the use situation of the input device 1 and also meet the needs of users for different tactile feedback.

In the foregoing embodiment, the operating portion 204 of the input device 1 is exposed from the bottom shell 1224 and the operating portion 204 is operated in a rotating manner; however, in practice, it is not limited to this. Please refer to Figure 5 to Figure 8. According to an embodiment, an input device 3 includes a device housing 32, a control module 34 (shown schematically in FIGS. 5 and 6 in dashed lines), a roller 36, an elastic hook 38, and an adjustment mechanism 40. The roller 36 is rotatably disposed in the device housing 32 and has a wheel portion 362 and a rotating shaft 364 fixedly connected to the wheel portion 362. The wheel portion 362 protrudes from the device housing 32. The rotating shaft 364 has a peripheral surface 3642 and a plurality of tooth grooves 3644 on the peripheral surface 3642. The elastic hook 38 is disposed in the device housing 32 adjacent to the roller 36 and can be inserted into or separated from the plurality of tooth grooves 3644. The adjustment mechanism 40 is arranged in the device housing 32 and includes a linkage portion 402 and an operating portion 404. The linkage portion 402 is movably arranged and connected to the elastic hook 38, and the operating portion 404 is connected to the linkage portion 402 and exposed to the device housing 32. Thereby, the user can operate the operating portion 404 to move the elastic hook 38 via the linkage portion 402 to disengage the elastic hook 38 from the plurality of tooth grooves 3644 or to change the engagement between the elastic hook 38 and the plurality of tooth grooves 3644 Degree (including partial engagement, full engagement, and contact force). The difference between the input device 3 and the input device 1 is mainly that the adjustment mechanism 40 links the elastic hook 38 to generate rotation resistance to the roller 36 in specific structural details, but the actuation logic is still the same, so in principle, the following will focus on the adjustment mechanism 40 linking the elastic hook The structure details of hook 38. For other descriptions of the components of the input device 3, please refer to the relevant descriptions of the input device 1, and will not be repeated.

The linkage portion 402 includes a first linkage portion 4022, a pivot portion 4024 and a second linkage portion 4026, and the pivot portion 4024 connects the first linkage portion 4022 and the second linkage portion 4026. The linkage portion 402 is pivotally connected to the roller support structure 324 via the pivot portion 4024 to be pivotally connected to the device housing 32. The first link portion 4022 abuts against the operating portion 404, and the second link portion 4026 abuts against the elastic hook 38. In this way, the user can slide the operating portion 404 so that the operating portion 404 is linked to the elastic hook 38 via the linkage portion 402 so that the elastic hook 38 disengages or engages with the plurality of tooth grooves 3644.

In this embodiment, the elastic hook 38 utilizes the elasticity of a torsion spring 42 to reset. The torsion spring 42 is disposed on the roller support structure 324, one end 42 a of the torsion spring 42 abuts against the roller support structure 324, and the other end 42 b extends to form an elastic hook 38. The torsion spring 42 drives the elastic hook 38 to escape from the plurality of tooth grooves 3644. The elastic hook 38 includes a groove 382 and a hook portion 384. The groove 382 is formed extending from the end 42 b of the torsion spring 42 and is located between the hook portion 384 and the body of the torsion spring 42. The second link portion 4026 is received in the groove 382 and abuts against the elastic hook 38 via the groove 382. The elastic hook 38 can be elastically deflected through the torsion spring 42 to realize the action of disengaging or engaging the plurality of tooth grooves 3644. In practice, the elastic hook 38 can also be directly and deflectably disposed on the roller support structure 324. For example, the elastic hook 38 is implemented in a cantilever structure, and one end of the elastic hook 38 is fixed to the roller support structure 324, which can also be elastically deflected and separated Or the action of engaging the plurality of tooth grooves 3644.

In this embodiment, the user can slide the operating portion 404 according to their needs to change the degree of engagement between the elastic hook 38 and the plurality of tooth grooves 3644 or to disengage the elastic hook 38 from the plurality of tooth grooves 3644. Therefore, the structural interference between the elastic hook 38 and the plurality of tooth grooves 3644 is not limited to presence or absence, but can be adjusted. For other descriptions of the influence of the structural interference between the elastic hook 38 and the plurality of tooth grooves 3644 on the rotation resistance of the roller 16, please refer to the previous description about the structural interference between the elastic hook 18 and the plurality of tooth grooves 1644. Another repeat. In addition, the operating part 404 can in principle also provide the user with paragraph-less adjustments to the position of the elastic hook 38, but in practice, paragraph-like adjustments can be provided by means of indicator marks, limit positions or positioning structures to facilitate The user adjusts quickly. In this embodiment, the input device 3 further includes a switch 44 disposed in the device housing 32, electrically connected to the control module 34, and connected to the operating part 404. When the operating portion 404 slides, the state of the switch 44 can be switched, and the control module 34 can sense the structural interference between the elastic hook 38 and the plurality of tooth grooves 3644 through the state of the switch 44, which can increase the flexibility of practical applications.

In addition, in this embodiment, the roller support structure 324 includes a roller bracket 3242 and a pivot bracket 3244. The pivot bracket 3242 is fixed to the bottom shell member 3224 of the housing 322, and the roller bracket 3242 is pivotally connected to the pivot bracket 3242. And the roller 36 is supported via the rotating shaft 364. The pivotal portion 4024 of the linkage portion 402 is pivotally connected to the roller bracket 3242, and the elastic hook 38 is rotatably disposed on the roller bracket 3242. Moreover, in this embodiment, the pivot bracket 3244 also allows the roller bracket 3242 to pivot up and down relative to the bottom shell 3224. The input device 3 further includes a switch 45 disposed in the device housing 32, electrically connected to the control module 34, and located under the roller bracket 3242. When the roller 36 is pressed down, the roller bracket 3242 deflects downward to trigger the switch 45.

In the input devices 1, 3, the rotation resistance of the rotating shafts 164, 364 of the rollers 16, 36 is caused by the structural interference (between the elastic hooks 18, 38 and the rotating shafts 164, 364); but in practice, this is not the case. Is limited. Please refer to FIG. 9, which shows an input device 5 similar in structure to the aforementioned input device 1.
