[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0024] Example 1

[0025] Reference Figure 1-5 As illustrated, this embodiment provides an installation structure for a scroll wheel button, which solves the problems of traditional scroll wheel buttons lacking freedom of movement during assembly, requiring a separate molded bracket to ensure installation accuracy, thus demanding high mold precision, and being difficult to disassemble and maintain.

[0026] In this embodiment, the mounting structure includes a roller 1, a loading plate 2, an elastic element 3, and a housing 4. The roller 1 is first mounted on the loading plate 2 via the elastic element 3, and then mounted on the housing 4 after being assembled together, thereby realizing the installation of the roller 1.

[0027] Specifically, the roller 1 is assembled on the loading plate 2 to form a combined component, which allows for the simultaneous removal and installation of the roller 1 and the loading plate 2. The assembly of this combined component can be achieved simply through the outer casing 4, without the need for a separate mold with a bracket, thus simplifying the assembly process.

[0028] In one embodiment, one side of the roller 1 is mounted on the loading plate 2 via an elastic element 3. The elastic element 3 provides the one side of the roller 1 with a degree of freedom of movement in the spatial direction. The other side of the roller 1 can be mounted on the loading plate 2 via a bearing, support column, or other means to enable the roller 1 to roll.

[0029] In this method, the elastic element 3 has elastic degrees of freedom in the up and down, left and right, front and back, and more directions at angles between the above directions, which can be summarized as spatial degrees of freedom. It is easy to understand that this degree of freedom is realized by the elasticity of the elastic element 3, which can be made of plastic, rubber or metal materials. The specific structure can be long strip, elliptical, bent or more irregular shapes, as long as it does not affect its degrees of freedom in each direction.

[0030] In this method, the connection between the elastic element 3, the roller 1, and the loading plate 2 can be achieved by directly setting a shaft hole on the top or side of the elastic element 3, with one end of the roller 1 passing through the shaft hole to achieve the rotation of the roller 1 while connecting the elastic element 3 and the side end; or by indirectly setting other structures with shaft holes for the side shaft of the roller 1 to rotate, such as a directional block with a shaft hole, a circular block, or other structures with shaft holes of different shapes. Therefore, no specific limitation is made in this embodiment.

[0031] In one embodiment, the aforementioned combined component is confined and installed inside the outer casing 4, with the roller 1 facing inwards and partially exposed on the surface of the outer casing 4 through the opening 41. In this embodiment, the exposed portion of the roller 1 is used by the user to rotate the roller 1. Regarding the confined and installed component inside the outer casing 4, refer to... Figure 5 As illustrated, a groove with the same shape as the loading plate 2 can be provided on the outer shell 4, and a limiting post corresponding to the loading plate 2 can be provided. The loading plate 2 can be installed on the outer shell 4 by positioning through the groove and the limiting post, but it also includes the method of directly fixing the loading plate 2 to the loading plate 2 by means of screws, glue or interference fit.

[0032] Example 2

[0033] In the above embodiments, the specific structure of the elastic element 3 is not limited. In this embodiment, a more specific optimization method is proposed for the connection between the elastic element 3, the roller 1, and the loading plate 2. The elastic element 3 includes a support ring 31 and a limiting foot 32. The support ring 31 is sleeved on the moving shaft 11 at one end, and the corresponding other end is a fixed shaft 12. The fixed shaft 12 is installed on the loading plate 2 by means of a shaft seat, support column, etc. in the above embodiment. In this way, both ends of the roller 1 are installed on the loading plate 2.

[0034] In this method, the elastic element 3 is mounted on the loading plate 2 via the limiting foot 32. Based on the description of the above embodiment, the limiting foot 32 in this embodiment can be implemented by various structures. For example, the limiting foot 32 can be directly fixed to the loading plate 2 by welding, gluing, or other methods by at least one elastic support. As an optimization in this embodiment, the limiting foot 32 is arranged symmetrically, and the bottom is provided with an inwardly bent recess 321. The recess 321 falls into the limiting hole 21 and is stuck after being elastically squeezed inward. Because the recess 321 has a rebound force that abuts against the limiting hole 21, the connection between the limiting foot 32 and the loading plate 2 is realized. Since the thickness of the limiting foot 32 is smaller than the diameter of the limiting hole 21, the elastic element 3 can have a certain amount of room for movement, and it can move left and right relative to the moving shaft 11.

[0035] In one embodiment, the support ring 31 is fitted onto the moving shaft 11 at one end. Since the roller 1 will roll frequently, there is rolling friction between the support ring 31 and the moving shaft 11, which affects the smoothness of the roller 1's rolling and also causes wear. Therefore, in this embodiment, a bushing 5 is fitted onto the moving shaft 11, and the support ring 31 is fitted onto the bushing 5.

[0036] In one embodiment, the elastic element 3 and the bushing 5 are positioned to limit the left and right movement of the roller 1. Specifically, brackets 42 are provided inside the outer shell 4 and on both sides of the opening 41. The roller 1 is limited to the left and right movement between the two brackets 42, that is, the body of the roller 1 is limited between the two brackets 42. The moving shaft 11 and the fixed shaft 12 rest on the brackets 42 and have a vertical movement range, but the roller 1 cannot move in the left and right direction.

[0037] Furthermore, an annular groove 43 is provided on the outer side of the bracket 42 at the end of the moving shaft 11. The elastic element 3 is located on the outer side of the bracket 42, and the top of the support ring 31 falls into the annular groove 43 for limitation. When the roller 1 is assembled on the loading plate 2 to form a combined component, the support ring 31 can move left and right, realizing convenient disassembly and installation of the roller 1 on the loading plate 2. However, when the loading plate 2 is assembled towards the inside of the shell, the support ring 31 falls into the annular groove 43 and cannot move left and right. Its elasticity will push the end of the moving shaft 11 upward while it can also move downward under pressure. When the mold opening accuracy between the loading plate 2, the roller 1 and the outer shell 4 is not high enough, there will be assembly differences, which will cause the roller 1 to tilt left and right and up and down. However, due to the assembly freedom in this embodiment, and under the constraint of the opening 41 and the bracket 42, the two ends of the roller 1 can have a certain coaxiality and the assembly is more compact. Therefore, it no longer depends on the mold opening accuracy, which not only saves a bracket, but also simplifies the assembly and reduces the assembly process requirements.

[0038] Furthermore, the annular groove 43 is a groove within the bushing groove 44, and the bushing groove 44 is used to limit the bushing 5. Both groove 43 and bushing groove 44 are located on the outside of the bracket 42. The bushing 5 is sleeved on the moving shaft 11, and the support ring 31 is sleeved on the bushing 5. However, when the loading plate 2 is assembled towards the inside of the shell, the bushing 5 falls into the bushing groove 44 and is limited, while the support ring 31 on its outer surface falls into the annular groove 43 and is limited. Therefore, both the bushing 5 and the support ring 31 are limited to the left and right. At the same time, due to the elasticity of the support ring 31, the bushing 5 and the moving shaft 11 are subjected to an upward force, ensuring that the bushing 5 and the support ring 31 are in close contact with the groove 43 and the bushing groove 44. Thus, the mold opening accuracy requirement is low. It is easy to understand that the allowable assembly error can be eliminated by the elasticity of the support ring 31.

[0039] Example 3

[0040] This embodiment proposes an electronic adjustment device, including the mounting structure of the roller button described in the above embodiment, referring to... Figure 6-8 The illustration shows the application of this mounting structure on an electronic handwheel. It also includes applications on electronic devices with scroll wheel adjustment buttons, such as scroll wheel speed adjustment structures for car steering wheels, mice, keyboards, dashboards, fitness equipment, neck massagers, handles, microphones, etc. The scroll wheel buttons on the above-mentioned electronic products can all be set as the mounting structure of the scroll wheel buttons in the above embodiments.

[0041] In one application of this embodiment, the loading plate 2 is a circuit board. The fixed shaft 12 on the other end of the roller 1 is supported and mounted on the loading plate 2 via an encoder 6. The encoder 6 is electrically connected to the loading plate 2 and is used to transmit the rolling amount of the roller 1. The encoder 6 is an existing component. The roller 1 drives the turntable, and the turntable contacts make electrical contact with the fixed contacts on the base to generate an on / off signal, which is responsible for converting the physical rotation into an electrical signal for computer recognition. The speed can be adjusted by rotation, etc. The circuit board is also an existing integrated electronic system, responsible for converting physical operations into digital signals. Its core principle involves signal acquisition, processing, and communication. Its functional implementation and its own principle will not be described in detail here.

[0042] To facilitate adaptation, it's easy to understand that the mounting structure of the scroll wheel button in this embodiment serves as the handwheel shell when applied to an electronic handwheel, the steering wheel shell when applied to a car steering wheel, the mouse shell when applied to a mouse, the keyboard shell when applied to a keyboard, and the dashboard shell when applied to a dashboard, etc. Therefore, the shell 4 can be adapted to the shell structure of the actual electronic product.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here.
