Detailed Description

The following is a specific embodiment to illustrate the embodiments of the present disclosure related to a "wireless charging mouse", and those skilled in the art can easily understand the advantages and effects of the present disclosure from the disclosure of the present disclosure. The invention is capable of other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. The drawings of the present invention are merely schematic illustrations, and are not intended to be drawn to scale, i.e., to reflect the actual dimensions of the components involved.

The following embodiments will further explain aspects of the present invention in detail, but do not limit the scope of the present invention in any way.

Fig. 1 to 7 are schematic views of a wireless charging mouse according to an embodiment of the invention. The wireless charging mouse (hereinafter referred to as mouse) of the present embodiment mainly includes an upper casing 1, a lower casing 2, and a coil board 3. In addition, it should be noted that the mouse of the embodiment further includes other components, such as various components required for general mouse operations, for example, a wheel, a button, and the like, which are not required technical features of the present invention, and therefore, are not described in detail. However, the features and characteristics of the present embodiment will be described in more detail below.

Further, the lower housing 2 is locked under the upper housing 1, and an accommodating space is formed between the upper housing 1 and the lower housing 2 for accommodating electronic components, such as the track sensing module 4. The track sensing module 4 is used for determining the moving direction and the moving distance of the mouse, so as to complete the positioning of the cursor, and may be an optical track sensing module or a laser track sensing module. The lower housing 2 has an opening 21 for exposing the track sensing module 4.

The coil plate 3 is integrally covered in the lower case 2. Specifically, the coil plate 3 is integrally covered in the lower case 2 by insert molding, and the coil plate 3 and the lower case 2 are formed as a one-piece case structure. The coil plate 3 may be entirely covered in the lower case 2 or partially covered in the lower case 2. The size of the outer contour of the coil plate 3 can be matched with the size of the lower shell 2, so that the magnetic induction is increased, and the inner space of the mouse is not occupied.

Further, the coil plate 3 has a plate body 31 and a coil 32 formed on the plate body 31. The coil 32 may be a coil formed by copper-coating and etching on the board body 31. The board 31 may be a Rigid PCB or a Flexible PCB, and is preferably made of Polyimide (PI), and the material itself has high thermal stability, radiation resistance and heat resistance, and further allows processing at a temperature as high as 500 ℃. Therefore, the coil plate 3 has good heat resistance, so that the molten plastic material can be directly distributed around the coil plate 3 in the embedding and injection molding process, and an integrally molded shell structure can be formed after solidification. As shown in fig. 2 to 4, the coil 32 is shaped to correspond to the contour of the plate 31 and to surround the inner side of the outer contour of the lower case 2. In addition, the coil 32 has two circuit contacts 321, and the inner side surface of the lower case 2 has a contact window 22 corresponding to the two circuit contacts 321, so that the two circuit contacts 321 are exposed from the contact window 22.

Furthermore, the plate body 31 of the coil plate 3 has an opening 311 and a plurality of positioning portions 312 extending from the periphery of the opening 311. The positioning portion 312 can be used to cooperate with the positioning structure to position the plate 31 in the mold cavity, so that the lower case 2 can be integrally combined with the coil plate 3 after the lower case 2 is molded in the mold cavity. The plate body 31 of the coil plate 3 also has a plurality of positioning holes 313 recessed from the periphery of the opening 311. The positioning hole 313 can be used to match with a positioning structure, such as a positioning post, to position the plate 31 in the lower housing 2 of the mouse.

In addition, the shape of the coil 32 may vary from application to application. For example, the coil 32 may be a circular, rectangular, square, and irregularly-shaped coil. In the present embodiment, the coil 32 is an irregular-shaped coil to correspond to the contour of the plate body 31.

In summary, the coil board is covered in the lower casing of the mouse in the embedding and injection molding manner, instead of the traditional way of arranging the coil board on the lower casing of the mouse in a stacking manner. Thus, the present invention can obtain at least the following advantages: the invention can more effectively utilize the internal space of the mouse; the stacking height of the coil plate and the lower shell of the mouse is not required, so that the coil plate is thinner and thinner; thirdly, the size of the coil plate is matched with that of the lower shell of the mouse, so that magnetic induction is increased; and (IV) the coil plate is hidden in the lower shell of the mouse, so that the coil plate cannot be damaged when the mouse is assembled, and the assembly reject ratio is reduced.

The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the claims of the present invention, so that all equivalent changes made by using the contents of the present specification and the drawings are included in the scope of the claims of the present invention.
