[0040] The bottom plate foot pad structure further comprises a foot pad set, the foot pad set is installed at the bottom of the connecting plate, and the bottom of the foot pad set is in contact with the working surface. The foot pad set has a plurality of, each of the foot pad set has one or more continuous or discontinuous foot pads 2; the bottom of the connecting plate has a plurality of support areas, and the smallest rectangle containing the bottom surface projection area of all foot pads in the foot pad set is the support area of the foot pad set; the bottom of the connecting plate has three mutually exclusive foot pad sets, each foot pad set corresponds to one support area, and the aforementioned three points are taken as the centers of the circular areas, and the circular areas with a radius of 30mm are called edge areas; the three support areas intersect with the three edge areas respectively.

[0041] As shown in FIG. 3, a rectangular area represents a support area of one insole set, and a circle or an ellipse or other irregular shape in the rectangular area represents one insole 2. The (a), (b) and (c) parts of FIG. 3 respectively represent layout examples of the insole 2 in different support areas. The (a) part of FIG. 3 represents three discontinuous insoles 2 in the support area. The (b) part of FIG. 3 represents one insole 2 in the support area. The (c) part of FIG. 3 represents two continuous insoles 2 in the support area, each of which is tangent to the edge of the support area to obtain a minimum rectangular area.

[0042] As shown in FIG. 4, A, B and C represent three points on the outer contour of the bottom projection of the connecting plate 1, which constrain the shape of the bottom of the connecting plate 1. The rectangular shaded part represents three support areas, each of which has one or more continuous or discontinuous insoles 2. The edge area is set with the points A, B and C as the center and a certain length as the radius, and the edge area intersects with the support area, so that the insole 2 in the support area is as close as possible to the corresponding A, B or C point, and the insole 2 is arranged at the best position on the bottom of the connecting plate 1 to ensure the stability of the mouse movement.

[0043] The size of each support area is less than 30 mm x 30 mm. Preferably, the size of each support area is less than 20 mm x 20 mm.

[0044] Preferably, the insole 2 is made of wear-resistant and smooth material, such as Teflon or ceramic material.

[0045] Preferably, there are three points on the outer contour of the bottom projection of the connecting plate 1, and the ratio of the area of the triangle formed by the three points to the area of the outer contour of the bottom projection of the connecting plate 1 is greater than 0.7. Further, there are three points on the outer contour of the bottom projection of the connecting plate 1, and the ratio of the area of the triangle formed by the three points to the area of the outer contour of the bottom projection of the connecting plate 1 is greater than 1.

[0047] Preferably, the depth of the groove is 0.3 mm, and the thickness of the insole 2 is 0.3-0.7 mm greater than the depth of the groove.

[0048] In this embodiment, the groove is a circular slot with a size of 8 mm x 8 mm and a depth of 0.3 mm. The area of the insole 2 matches the area of the groove, and the thickness of the insole 2 is 0.6 mm. The groove can also be a round rectangular slot or other structural slot.

[0049] The connecting plate 1 includes a plurality of mounting holes 10 distributed at corresponding positions of the connecting plate 1 for mounting the mouse.

[0050] Referring to Figs. 5-6 of the accompanying drawings, the utility model further provides a mouse, which comprises the bottom plate foot pad structure and a mouse body 3. The bottom of the mouse body 3 is provided with a threaded hole matched with the mounting hole 10 of the connecting plate 1, and the threaded hole of the mouse body 3 is connected with the mounting hole 10 of the connecting plate 1 through a bolt along the bottom of the connecting plate 1.

[0051] The several mounting holes 10 distributed on the connecting plate 1 can be suitable for mounting mouse bodies 3 of different specifications, and are good in universality.

[0052] The following compares the shapes and layouts of two conventional mouse foot pads with those of the utility model, and it is illustrated that the mouse foot pad of the utility model can effectively reduce the change range of the mouse resistance center.

[0053] Referring to Fig. 7 of the accompanying drawings, parts (a) and (b) of Fig. 7 are schematic diagrams of the shapes and layouts of two conventional mouse foot pads. Part (a) of Fig. 7 is layout 1, and the mouse bottom plate of layout 1 generally has at least four supporting points (i.e. independent foot pads). The size of the foot pad of each supporting point is usually small. Since the mouse bottom plate is deformed in the injection molding or other forming process, the bottom plate is not an absolute plane. At the same time, the working surface of the mouse is not an absolute plane due to process limitations, and the height and curvature of the working surface usually have slight differences. Therefore, in the actual use of the mouse, it is a small probability event that the four supporting points simultaneously contact the working surface, and the absolute majority of the working conditions in actual use are that the mouse bottom plate randomly has one supporting point suspended. Part (b) of Fig. 7 is layout 2, and the mouse bottom plate of layout 2 is commonly seen in game mice. The bottom plate generally comprises two large-area foot pads. However, in actual use, due to the deformation of the mouse bottom plate in the injection molding or other forming process and the uneven thickness caused by the cutting process of the foot pad, the foot pad cannot be completely attached to the working surface. The partial attachment and partial suspension still account for the vast majority of working conditions, and the attached part is generally located near the two sides of the mouse. The wear of the foot pad after use can also prove this point.

[0054] Fig. 8 and Fig. 9 are schematic diagrams of the resistance center variation of the two kinds of traditional mouse foot pad layouts, respectively. For Fig. 8, the (a1) part and the (a2) part of Fig. 8 show the working conditions in which the support points A, B and the working surface are in contact, and one of the support points C and D is suspended. When the support point D is suspended, the support points ABC are in contact with the working surface, and the resistance center of the mouse when moving is in the triangular area formed by the three points ABC. According to the variation of the load of the three points ABC, the resistance center moves in the area 1 near the center point of the triangle ABC. When the support point C is suspended, the support points ABD are in contact with the working surface, and the resistance center of the mouse when moving is in the triangular area formed by the three points ABD. According to the variation of the load of the three points ABD, the resistance center moves in the area 2 near the center point of the triangle ABD. Thus, when the support point changes from the support point C to the support point D during the movement of the mouse, the resistance center changes from the area 1 to the area 2, resulting in a large deviation. For Fig. 9, similar to Fig. 8, the (b1) part and the (b2) part of Fig. 9 show the variation of the resistance center when the support areas A and B are in contact with the working surface and the support areas C or D are suspended in the two large foot pad coverage areas. When the support point changes from the support area C to the support area D, the resistance center changes from the area 1 to the area 2, resulting in a large deviation. The traditional mouse foot pad structure and layout will cause unevenness during the operation of the mouse and poor stability.

[0055] The mouse foot pad of the utility model of Fig. 10 limits the arrangement area of the foot pad to three, so that even if there is a deviation in the flatness of the mouse bottom plate and the working surface, the contact point changes during use, and the resistance center still maintains a small deviation amplitude. The variation amount of the resistance feedback during the movement of the mouse can be reduced, as shown in the (c1) part and the (c2) part of Fig. 10, the resistance center changes little in the different specific contact positions of the mouse foot pad and the working surface. At the same time, by enlarging the ratio of the area of the triangle with the point on the outer contour of the bottom surface projection as the vertex to the area of the outer contour of the bottom surface projection, the stability of the mouse during movement can be improved, and the overturning moment during the movement of the mouse can be resisted.

[0056] Because the traditional foot pad has a large coverage size and a large number, and the contact surface of the mouse bottom is not an absolute plane, the resistance center of the mouse will change greatly during movement. The structure of the embodiment limits the arrangement area of the foot pad to three, which can effectively reduce the variation amplitude of the resistance center of the mouse, so that the operation process of the mouse is smooth and the reaction is sensitive.

[0057] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge are not described in detail herein. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
