Description

Adjustable scroll wheel assembly and mouse Technical Field

[0001] This invention relates to mouse accessories, specifically to a scroll wheel assembly with adjustable scrolling feel and a corresponding mouse. Background Technology

[0002] Application number "202321176094.9", patent title "A roller component with electrically adjustable rolling damping and a mouse", provides a roller component that can precisely control the rolling distance and speed of the roller. It achieves the change of roller damping by changing the contact / abutment distance between the damping rod and the inner wall of the roller.

[0003] However, this roller component cannot flexibly adjust the pressure between the damping rod and the inner wall of the roller while keeping the damping rod and the inner wall of the roller in a tight fit, i.e., the distance remains constant, which cannot meet the user's demand for a more personalized and refined roller feel. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a scroll wheel assembly and mouse with adjustable scrolling feel.

[0005] To achieve this technical objective, the present invention provides a roller assembly with adjustable rolling feel, comprising a bracket and a movable annular roller mounted on the bracket. An electric motor module is assembled on the bracket, and a swing arm is pivotally connected to the bracket. One end of the swing arm is a damping rod extending to the inner wall of the roller, and the other end is an abutment end. An abutment member is movably mounted on the bracket, having a variable elastic end capable of abutting against the abutment end of the swing arm. The electric motor module is driven by the abutment member. When the electric motor module drives the abutment member to move, it changes the abutment position between the variable elastic end and the abutment end, thereby applying different elastic forces to the abutment end. Furthermore, the abutment end, through the swing arm transmission, changes the pressure applied to the inner wall of the roller by the damping rod.

[0006] Preferably, the elastic variable end of the abutment includes a rocker arm and an elastic element, the rocker arm being pivotally connected to the abutment, and the elastic element being disposed on the abutment to provide tension to the rocker arm.

[0007] Preferably, the elastic element is any one of torsion spring, sheet spring, spring, or silicone.

[0008] Preferably, the abutting end of the swing arm is an "L"-shaped structure protruding downward from one end of the swing arm, and the end of the rocker arm is a sloping platform. The end of the "L"-shaped structure facing the rocker arm is arc-shaped.

[0009] Preferably, the abutment is provided with a limiting end for determining the maximum tilting angle of the tilting arm.

[0010] Preferably, the electric motor module includes an electric motor and a reduction gear set, and the abutment is provided with a rack structure. The rack structure meshes with the reduction gear set for transmission, and the electric motor drives the rack structure through the reduction gear set to move the abutment.

[0011] Preferably, the inner wall of the roller is configured with a wave-like or toothed structure.

[0012] Preferably, the swing arm is also provided with an elastic reset member. When the abutment member leaves the abutment end of the swing arm, the elastic reset member causes the damping pressure rod to move away from the inner wall of the roller.

[0013] The present invention also provides a mouse that employs a scroll wheel assembly with adjustable scrolling feel as described in any of the preceding claims.

[0014] The beneficial effects of this invention are as follows: This solution achieves fine adjustment of the rolling segment feel by adjusting the pressure of the damping rod against the inner wall of the roller; the solution ingeniously applies different elastic forces to the abutting end by changing the contact position between the variable elastic end and the abutting end, and changes the pressure of the damping rod on the inner wall of the roller by means of the lever transmission mechanism of the swing arm; this design makes the adjustment of damping pressure more flexible and diverse, providing users with a more personalized roller flicking experience.

[0026] The present invention will be 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; these embodiments are only some embodiments of the present invention; other embodiments obtained based on this application without inventive effort are all within the scope of protection of the present invention.

[0027] In the following embodiments, it should be noted that the terms "upper," "lower," "left," "right," "inner," "outer," "top / bottom," etc., are all based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of clearly describing this embodiment. They do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application. At the same time, the terms "first" and "second" in the embodiments are only used for descriptive purposes and do not represent an indication or implication of relative importance.

[0028] As shown in Figures 1-2, a specific embodiment of the present invention is a roller assembly with adjustable rolling feel, including a bracket 1 and a ring-shaped roller 2 that can be moved on the bracket 1. An electric motor module 3 is assembled on the bracket 1, and a swing arm 4 is also pivotally connected to the bracket 1. One end of the swing arm 4 is a damping rod 401 extending to the inner wall 201 of the roller, and the other end is an abutment end 402. The abutment member 5 is a movable component on the bracket 1 and has a variable elastic end. The variable elastic end can abut against the abutment end 402 of the swing arm 4. The abutment member 5 is drivenly connected to the electric motor module 3.

[0029] The middle part of the swing arm 4 is provided with a pivot column 403, and the bracket 1 is provided with a pivot groove 101. The middle part of the swing arm 4 is mounted on the pivot groove 101 of the bracket 1 through the pivot column 403. One end of the swing arm 4 is a damping pressure rod 401 connected to the inner wall 201 of the roller, and the other end is an abutment end 402 connected to the elastic variable end of the abutment member 5, which acts as a lever. The position of the damping pressure rod 401 is changed by swinging the swing arm 4 to change the pressure on the inner wall of the roller.

[0030] The swing arm 4 transmits force from the variable elastic end to the damping rod 401, which applies pressure to the inner wall 201 of the roller. The magnitude of this pressure is determined by the relative position of the swing arm 4 and the abutment 5, and can therefore be adjusted by driving the abutment 5 to move via the electric motor module 3. When the electric motor module 3 drives the abutment 5 to move, it can change the contact position between the variable elastic end and the abutment end 402, thereby applying different elastic forces to the abutment end 402, and changing the pressure applied to the inner wall 201 of the roller by the damping rod 401 through the transmission of the swing arm 4. When the abutment 5 leaves the swing arm 4 (when the two are not in contact), the damping rod 401 loses the force provided by the elastic variable end, allowing the damping rod 401 to disengage from the inner wall 201 of the roller. In this case, the rotation of the roller is not limited by the damping of the damping rod, and the roller can achieve a flywheel mode. In the preferred embodiment, a torsion spring-like elastic reset member is provided on the swing arm 4 to ensure that the damping rod 401 is reset to a state away from the inner wall 201 of the roller when the abutment 5 leaves the swing arm 4.

[0031] As a specific embodiment of this application, as shown in Figures 3-7, the variable-elastic end of the abutment member 5 includes a rocker arm 501 and a torsion spring 502. The rocker arm 501 is pivotally connected to the abutment member 5, while the middle part of the torsion spring 502 is pivotally connected to the abutment member 5, providing tension to the rocker arm 501. The upper arm of the torsion spring 502 abuts against the lower part of the rocker arm 501, and a torsion spring seat 503 extends from the bottom of the abutment member 5. The lower arm of the torsion spring 502 abuts against the torsion spring seat 503, ensuring that the torsion spring 502 maintains a stable position and orientation during operation.

[0032] Of course, in addition to torsion springs, any elastic element in the prior art, such as sheet metal, springs, silicone, etc., can be used as the elastic element that provides tension to the rocker arm 501.

[0033] To further improve the efficiency of force transmission, the abutment end 402 of the swing arm 4 is an "L"-shaped structure protruding downward from one end of the swing arm 4, and the end of the rocker arm 501 is a ramp surface 505, which makes the contact end 402 of the swing arm 4 more stable when it contacts the end of the rocker arm 501. The end of the "L"-shaped structure facing the abutment 5 is arc-shaped, which can reduce the friction when it contacts the rocker arm 501, making the movement of the abutment 5 smoother. In particular, when the rocker arm 501 moves away from the abutment end 402 and then moves back towards the abutment end 402, the rocker arm 501 can enter the area below the abutment end 402 more smoothly.

[0034] The movement trajectory of the rocker arm 501 in this application is shown in Figures 8-10. The rocker arm 501 is connected to the abutment member 5 through the pivot point 506. The rocker arm 501 can rotate around the pivot point 506. When the damping pressure rod 401 abuts against the inner wall 201 of the roller, the position of the abutment end 402 is kept constant. At this time, the rocker arm 501 is driven to move along with the abutment member 5 by the electric motor module 3. This rotation structure can ensure that the angle of the rocker arm 501 changes to prevent the rocker arm 501 from getting stuck with the abutment end 402.

[0035] When the rocker arm 501 is far away from the abutment end 402, in order to further limit the rotation range of the rocker arm 501, the abutment member 5 is also provided with a limiting end 507 for determining the maximum rocker angle of the rocker arm 501, to ensure that the rocker arm 501 can stay stably in the predetermined position during the adjustment process, and to prevent the rocker arm 501 from rotating excessively or accidentally leaving the predetermined position. This allows the rocker arm 501 to smoothly enter under the abutment end 402 when the abutment member 5 moves back towards the abutment end 402.

[0036] To protect the internal structure, both the electric motor module 3 and the abutment 5 are installed inside the housing 6. The abutment 5 and the electric motor module 3 abut against each other via a rack and pinion structure 504. The electric motor module 3 includes an electric motor 301 and a reduction gear set 302. The electric motor 301 drives the rack and pinion structure 504 through the reduction gear set 302 to move the abutment 5. The rack and pinion structure 504 converts the rotational motion generated by the electric motor module 3 into the linear motion of the abutment 5. Through cooperation with the reduction gear set 302, the rack and pinion structure 504 can precisely control the moving distance and speed of the abutment 5, thereby achieving precise adjustment of the damping and providing users with a more stable and reliable roller experience.

[0037] The inner wall 201 of the roller in this application is preferably configured as a wave or toothed structure. When the user rolls the roller, this structure can interact with the damping rod 401 to provide a more delicate segmented rolling feel. Different wave or toothed designs can produce different damping effects to meet the needs and preferences of different users.

[0038] The bracket 4 is also equipped with a flexible circuit board 7. Encoded electrical devices are attached to the flexible circuit board 7. Correspondingly, the roller is equipped with a trigger structure for triggering the encoded electrical devices to generate signals. This roller assembly can be applied to any encoded electrical devices in the prior art, such as Hall effect sensors, light-emitting elements and light-receiving elements forming a photodiode, etc. These are not innovative features of the present invention, so they will not be described in detail. Only the specific preferred embodiments shown in Figures 1 and 2 are described in detail: The trigger structure constructed inside the roller 2 is a ring of grating disk 202. The grating disk 202 is a disc-shaped structure with light-transmitting and light-blocking parts. In the roller assembly, the grating disk 202 is fixedly installed inside the roller and rotates with the rotation of the roller. The flexible circuit board 7 is equipped with a photodiode assembly 8 composed of light-emitting elements and light-receiving elements. The light-emitting elements and light-receiving elements are arranged on both sides of the grating disk 202. When the roller 2 rotates, the light-transmitting and light-blocking parts on the grating disk 202 pass between the light-emitting element and the light-receiving element in sequence, causing the light flux received by the light-receiving element to change and thus generate a corresponding signal output.

[0039] The present invention also provides a mouse that uses the above-mentioned scroll wheel assembly with adjustable scrolling feel.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present invention should be included within the protection scope of the present invention.
