Description

Technical Field

[0001] This utility model relates to the field of mice, and in particular to a mouse scroll wheel. Background Technology

[0002] A mouse is an external input device for computers and an indicator for positioning on the computer's display system. It is named for its resemblance to a mouse. Its standard name should be "mouse device," and its English name is "Mouse." The purpose of using a mouse is to make computer operation simpler and faster, replacing the cumbersome commands of the keyboard. With the development of technology, mice are divided into wired mice and wireless mice.

[0003] A mouse scroll wheel is a type of scroll wheel that can detect the scrolling direction and speed. A traditional mouse scroll wheel usually consists of an axle and a one-piece molded scroll wheel body. The outer surface of the scroll wheel body is covered with a rubber sleeve, and the two ends of the axle are located on the encoder and tactile switch.

[0004] However, existing mice are not very effective at achieving fast scrolling of the scroll wheel, have a heavy feel to the tactile feedback, and are expensive. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A mouse scroll wheel, including a mouse motherboard installed inside the mouse;

[0007] The mouse motherboard has a support bracket in the middle of the upper part, and a scroll wheel body is set at the upper end of the support bracket. The scroll wheel body includes a stator base and a stator cover that are interlocked. A shaft core is horizontally passed through the inner center of the stator base. Rotor magnets are set on the left and right sides of the shaft core respectively. A rotor gear is sleeved on the outer side of the stator base, and a scroll wheel sleeve is sleeved on the outer side of the rotor gear.

[0008] The mouse motherboard has a Hall module on one side of the bracket, and the scroll wheel sleeve has a Hall magnet on the spindle core on the side close to the Hall module.

[0009] As a further embodiment of this utility model: the upper end of the bracket is provided with a receiving cavity for installing the roller body, a limiting seat is provided on the side of the receiving cavity away from the Hall module, and a limiting block is provided on the outer side of the stator base to limit and cooperate with the limiting seat.

[0010] As a further embodiment of this utility model: a rotating groove for the Hall magnet to rotate and a rotating hole for the shaft core to rotate are provided on the other side of the receiving cavity.

[0011] As a further embodiment of this utility model, the stator base and stator cover are respectively provided with fixing grooves for fixing the rotor magnets.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. After assembling the stator base and rotor magnet and other related accessories, install them into the receiving cavity of the bracket. When rotating slowly, the mutual magnetic attraction between the rotor magnet and the rotor gear is used to achieve the scale sense of the traditional encoder. When rolling rapidly, the IC magnetic induction of the Hall module and Hall magnet can realize rapid rolling in the computer.

[0014] 2. By utilizing the attraction structure between the rotor gear and the rotor magnet, the wheel installed on the mouse scroll wheel on the market is usually formed by multi-piece stamping process and injection molding magnetization. The gear of this utility model is formed by powder metallurgy one-piece molding process, which improves labor costs and optimizes the simplicity of the structure, thereby reducing costs.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] A bracket 2 is provided in the middle of the upper part of the mouse motherboard 1. A roller body is provided at the upper end of the bracket 2. The roller body includes a stator seat 3 and a stator cover 4 that are interlocked. A shaft core 5 is horizontally passed through the inner middle of the stator seat 3. Rotor magnets 6 are provided on the left and right sides of the shaft core 5 respectively. A rotor gear 7 is sleeved on the outer side of the stator seat 3. A roller sleeve 8 is sleeved on the outer side of the rotor gear 7.

[0028] The mouse motherboard 1 has a Hall module 9 on one side of the bracket 2, and the scroll wheel sleeve 8 has a Hall magnet 10 on the shaft core 5 on the side close to the Hall module 9.

[0029] When rotating slowly, it can achieve the scale feel of a traditional encoder. The scale feel is achieved by the mutual magnetic attraction between the rotor magnet 6 and the rotor gear 7.

[0030] A further solution: The upper end of the bracket 2 is provided with a receiving cavity 11 for installing the roller body. A limit seat 12 is provided on the side of the receiving cavity 11 away from the Hall module 9. A limit block 13 is provided on the outer side of the stator seat 3 to limit and cooperate with the limit seat 12.

[0031] The limiting block 13 is inserted and fixed inside the limiting seat 12, so that the stator seat 3 is fixed inside the receiving cavity 11.

[0032] A further option: The other side of the receiving cavity 11 is provided with a rotating groove 14 for the Hall magnet 10 to rotate and a rotating hole 15 for the shaft core 5 to rotate.

[0033] It allows the scroll wheel sleeve 8 to rotate, enabling the mouse to scroll, which in turn drives the Hall magnet 10 to rotate, achieving rapid scrolling.

[0034] A further solution: The stator base 3 and the stator cover 4 are respectively provided with fixing grooves 16 for fixing the rotor magnet 6.

[0035] The position of the rotor magnet 6 can be fixed, so that the magnetic attraction between it and the rotor gear 7 can be used to achieve a sense of scale when rolling.

[0036] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
