## Abstract

A wireless charging mouse includes an upper housing, a lower housing, and a coil board. The lower housing is fixed to the upper housing and has an aperture for exposing a displacement sensing module. The coil board is integrally embedded in the lower housing by means of injection molding such that the coil board and the lower housing are formed as a one-piece structure.

## Claims

### Claim 1

A wireless charging mouse, comprising:
an upper housing;
a lower housing being fixed to the upper housing and having an aperture for exposing a displacement sensing module; and
a coil board being integrally embedded in the lower housing by means of injection molding such that the coil board and the lower housing are formed as a one-piece structure,
wherein the coil board is partially enclosed in the lower housing, and a top surface of the lower housing forms an inspection opening that exposes the terminals of the coil board for testing a short-circuit of the coil board,
wherein the coil board has a plate board and a coil formed on the plate board, and an outer contour of a rear portion of the coil is irregularly shaped the same as an outer contour of a rear portion of the lower housing,
wherein the rear portion of the coil has a first part, a second part connected to the first part, a third part connected to the second part, and a fourth part connected to the third part,
wherein an inner side of the first part and an inner side of the second part define a first angle there-between, the inner side of the second part and an inner side of the third part define a second angle there-between, and an outer side of the third part and an outer side of the fourth part define a third angle there-between, and wherein the first angle is set to be greater than the second angle, and the third angle is set to be greater than the first angle.

### Claim 2 (depends on 1)

The wireless charging mouse according to claim 1, wherein the first angle is set to be greater than 90 degrees, the second angle is set to be less than or equal to 90 degrees, and the third angle is set to be greater than 90 degrees.

### Claim 3 (depends on 1)

The wireless charging mouse according to claim 1, wherein the plate board has an opening and a plurality of positioning portions extending from a periphery of the opening.

### Claim 4 (depends on 3)

The wireless charging mouse according to claim 3, wherein the plate board is provided with a plurality of positioning notches recessed from the periphery of the opening.

### Claim 5 (depends on 1)

The wireless charging mouse according to claim 1, wherein the plate board is made of a polyimide material.
