Abstract

A wireless cursor control device for use with a computer system includes a main body, a wireless signal receiver, a storing portion and a resilient pad member. The main body generates a wireless signal to control a cursor of the computer system. The wireless signal receiver is swappable to be electrically connected to the computer system for receiving the wireless signal. The storing portion is disposed in the main body for accommodating the wireless signal receiver. The resilient pad member is engaged with the bilateral sides of the storing portion, and deformed to generate a restoring force when the wireless signal receiver is inserted into the storing portion. The resilient pad member is sustained against the wireless signal receiver according to the restoring force.

Claims

1. A wireless cursor control device for use with a computer system, comprising:

a main body for generating a wireless signal to control a cursor of said computer system;

a wireless signal receiver swappable to be electrically connected to said computer system for receiving said wireless signal;

a storing portion disposed in said main body for accommodating said wireless signal receiver; and

a resilient pad member engaged with the bilateral sides of said storing portion, and deformed to generate a restoring force when said wireless signal receiver is inserted into said storing portion, wherein said resilient pad member is sustained against said wireless signal receiver according to said restoring force;

wherein said storing portion comprises a first indentation structure and a second indentation structure in the bilateral side thereof to be engaged with said resilient pad member;

wherein said storing portion further comprises a third indentation structure for accommodating a universal serial bus connector of said wireless signal receiver therein, thereby facilitating positioning said wireless signal receiver within said storing portion;

a power switch unit in communication with said third indentation structure of said storing portion, wherein said wireless cursor control device is powered off when said wireless signal receiver is stored within said storing portion and said universal serial bus connector of said wireless signal receiver touches said power switch unit.

2. The wireless cursor control device according to claim 1 wherein said main body is a main body of a wireless mouse, and said computer system is selected from one of a personal computer and a notebook computer.

3. The wireless cursor control device according to claim 1 wherein said resilient pad member includes a first resilient semi-cylindrical pad and a second resilient semi-cylindrical pad to be sustained against said wireless signal receiver when said wireless signal receiver is stored within the storing portion.

4. The wireless cursor control device according to claim 3 wherein said first resilient semi-cylindrical pad and said second resilient semi-cylindrical pad are respectively embedded within said first indentation structure and said second indentation structure, and have a first trench structure and a second trench structure engaged with bilateral edges of a bottom plate of said storing portion.

5. The wireless cursor control device according to claim 1 wherein said wireless signal receiver further comprises a first notch and a second notch to be engaged with said first resilient semi-cylindrical pad and said second resilient semi-cylindrical pad of said resilient pad member.

6. The wireless cursor control device according to claim 1 wherein said wireless signal receiver is stored within said storing portion by a depressing approach, and said first resilient semi-cylindrical pad and said second resilient semi-cylindrical pad of said resilient pad member are sustained against said wireless signal receiver after said resilient pad member is engaged within said storing portion.

7. The wireless cursor control device according to claim 1 wherein the length of said storing portion is slightly greater than that of said wireless signal receiver, and said storing portion has an inclined plane for facilitating said wireless signal receiver to be stored within said storing portion in a slidable manner, so that said first resilient semi-cylindrical pad and said second resilient semi-cylindrical pad of said resilient pad member are sustained against said wireless signal receiver.
