Description

Technical Field

[0001] This utility model relates to the field of mouse technology, and specifically to a mouse trackball mounting structure. Background Technology

[0002] A mouse is an external input device for computers, serving as an indicator for positioning on the computer's display system using horizontal and vertical coordinates. It gets its name from its resemblance to a mouse. A trackball mouse is a type of mouse whose biggest advantage is that it doesn't require moving the mouse across the support surface like a mechanical mouse, thus saving space and reducing wrist fatigue for the user.

[0003] Existing trackball mice have the same mechanical sensitivity in every direction. However, in the gaming field, some games require rapid left and right head turning. When ordinary trackballs rotate rapidly left and right, they also rotate up and down, causing the cursor and view on the screen to wobble. It is difficult to achieve smooth left and right movement, making it difficult to control the rotation of the game view and prone to errors. Improvement is needed. Utility Model Content

[0004] To address the above problems, this utility model provides a mouse trackball mounting structure to solve one or more technical problems existing in the prior art, and at least provides a beneficial option or creates conditions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mouse trackball mounting structure includes a trackball and a mounting base. The trackball is disposed within the mounting base. Bearing seats are provided at both ends of the mounting base. Bearing assemblies are inserted into the bearing seats. One side of the bearing assembly is in contact with the trackball, and at least one side of the bearing assembly is in contact with an elastic element.

[0007] Preferably, a damping component is provided on one side of the bearing assembly facing into the mounting base, the other side of the bearing assembly is connected to an elastic element, and the damping component is in contact with a track ball.

[0008] Preferably, the bearing assembly includes an inner ring and an outer ring, with balls disposed between the inner and outer rings, the damping assembly connected to the inner ring, and the elastic element abuttingly connected to the outer ring.

[0009] Preferably, the damping component is a damping column, which includes a concave surface and a column body. One end of the column body is fixedly connected to the inner ring, and the other end is connected to the concave surface. The concave surface is in contact with the track ball.

[0010] Preferably, the column is fixedly connected to the outer ring, and the elastic element is abuttingly connected to the inner ring.

[0011] Preferably, the damping component consists of at least three pillars uniformly fixed to the inner ring, with the tops of the pillars abutting against the trackball.

[0012] Preferably, the support is connected to the outer ring, and the top of the support is connected to the trackball.

[0013] Preferably, the mounting base has a mounting hole at its bottom, and a photoelectric sensor is installed in the mounting hole.

[0014] Preferably, the bearing housing is cylindrical.

[0015] A lightweight mouse trackball mounting structure includes a trackball and a mounting base. The trackball is disposed within the mounting base. The mounting base has at least one bearing assembly. The bearing assembly includes an inner ring and an outer ring, with a ball bearing between the inner and outer rings. The outer ring abuts against the trackball. A fixing rod passes through the inner ring and is fixedly connected to the mouse. The fixing rod is also fitted with an elastic element, which abuts against the inner ring.

[0016] The beneficial effects of this utility model are:

[0017] This invention utilizes a vertical elastic element to push a bearing assembly against a trackball. When the trackball is slid left or right, the horizontal friction is less than the vertical friction, resulting in smoother horizontal rotation of the trackball. The oblique and vertical resistances are relatively greater, which translates to smoother left and right movement of the cursor. In games and other applications requiring rapid left and right turns, the viewing angle is smoother and does not wobble, leading to a better gaming experience.

[0018] The damping component is connected to the bearing assembly, and the damping component is in contact with the trackball. The friction between the damping component and the trackball is greater, which provides stronger constraint on the vertical rotation of the trackball. The left and right rotation of the trackball is relatively smoother, and the cursor and viewing angle are more stable.

[0019] The damping component is connected to the inner / outer ring of the bearing assembly, and the elastic element is abuttingly connected to the outer / inner ring. The damping component generates vertical friction force on the trackball without affecting the lateral rotation of the trackball. The structure is simple and effective. Attached Figure Description

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] Example 1: Refer to Figures 1 to 3 The present invention discloses a mouse trackball mounting structure, which is applied to a trackball mouse. It includes a mounting base 2 and a photoelectric sensor 3 disposed at the bottom of the mounting base 2. The trackball 1 is disposed within the mounting base 2. With the vertical direction of the mounting base 2 extending from its upper and lower ends as shown in the figure, the mounting base 2 has bearing seats 4 at both its upper and lower ends in the vertical direction. Bearing assemblies 5 are inserted into the bearing seats 4 and can slide within them. One side of each bearing assembly 5 abuts against the trackball 1, and the other side of one bearing assembly 5 abuts against an elastic element 7. The other end of the elastic element 7 abuts against the bearing cover 1 of the bearing seat 4. 2. The elastic element 7 pushes the bearing assembly 5 to connect tightly with the trackball 1. When the trackball 1 moves horizontally, the trackball 1 and one of the bearing assemblies 5 generate rolling friction. When the trackball 1 rotates vertically, the two bearing assemblies 5 and the trackball 1 generate friction. Therefore, when sliding the trackball mouse left and right, the horizontal friction is smaller than the vertical friction, so the horizontal rotation of the trackball is smoother. The resistance in the diagonal and vertical directions is relatively larger. This is reflected in the cursor, which moves more smoothly left and right. In games that require fast left and right turning, the view is smoother when turning left and right, and there is no up and down shaking of the view, resulting in a better gaming experience.

[0032] Specifically, the bottom of the mounting base 2 is provided with a mounting hole, and the photoelectric sensor 3 is installed in the mounting hole.

[0033] Specifically, the trackball 1 is made of stainless steel or other materials with a conductive coating on the surface.

[0034] Specifically, the bearing housing 4 is cylindrical, which makes the installation and sliding of the bearing assembly 5 more stable.

[0035] Example 2: See Figure 3 Unlike embodiment 1, both bearing assemblies 5 are connected to elastic elements 7 on their outer sides, resulting in less friction and smoother lateral rotation.

[0036] Example 3: See Figures 4 to 6 Unlike embodiment 2, a damping component 6 is provided on one side of the bearing assembly 5 facing the mounting base 2, and an elastic element 7 is abutting and connected on the other side of the bearing assembly 5. The damping component 6 is abutting and connected to the track ball 1. When the track ball 1 rotates in the vertical direction, the track ball 1 and the damping component 6 generate sliding friction under the action of the elastic element 7 and the damping component 6, and the sliding friction is more sufficient.

[0037] Specifically, the bearing assembly 5 includes an inner ring 8 and an outer ring 9, with balls between the inner ring 8 and the outer ring 9. A damping assembly 6 is connected to the inner ring 8, and an elastic element 7 is abutted against the outer ring 9. The damping assembly 6 generates a vertical frictional force on the trackball 1 without affecting the lateral rotation of the trackball 1.

[0038] Specifically, the damping component 6 is a damping column 10, which includes a concave surface 101 and a column 102. One end of the column 102 is fixedly connected to the inner ring 8, and the other end is connected to the concave surface 101. The concave surface 101 abuts against the track ball 1, and the contact area is large, which can provide greater vertical friction. In the preferred embodiment, the column 102 is connected to the outer ring 9, and the elastic element 7 abuts against the inner ring 8, making the connection more stable.

[0039] Example 4: Reference Figure 7-8 Unlike embodiment 3, the damping component 6 consists of at least three pillars 11 evenly fixed to the inner ring 8. The top of the pillars 11 is connected to the trackball 1, which can provide less friction and is suitable for scenarios where the vertical cursor is more sensitive.

[0040] Specifically, the support column 11 is connected to the outer ring 9, and the elastic element 7 is connected to the inner ring 8.

[0041] Example 5: A lightweight mouse trackball mounting structure, different from Example 1, omits the bearing housing 4. Specifically, it includes a trackball 1 and a mounting base 2. The trackball 1 is disposed within the mounting base 2. The mounting base 2 has at least one bearing assembly 5. The mounting base 2 has an opening through which the bearing assembly 5 passes. The bearing assembly 5 includes an inner ring 8 and an outer ring 9, with a ball bearing between the inner ring 8 and the outer ring 9. The outer ring 9 is abutted against the trackball 1. A fixing rod 13 passes through the inner ring 8 and is fixedly connected to the mouse. The fixing rod 13 is also fitted with an elastic element 7, which abuts against the inner ring 8. The elastic element 7 pushes the bearing assembly 5 into the mounting base 2, causing the outer ring 9 to abut against the inner ring 8. This example omits the bearing housing 4, resulting in a lighter overall weight and easier operation.
