BYD's patent information about "a multifunctional mouse" is authorized to be published. The patent publication number is CN2/KOOC-0/32/KOOC-0/0986U, and the publication date is 202/KOOC-0/May/KOOC-0/4. The utility model belongs to the technical field of electronic equipment, in particular to a multifunctional mouse, which comprises a mouse body, a control motherboard, a left button, a right button, a roller and a changeover switch. After the switch is turned on, the left key and the right key are given new key values, and the second key value of the left key and the second key value of the right key are both equivalent to a key value on the keyboard, so as to achieve the purpose of simulating the keyboard, and the mouse and the simulated keyboard can be switched freely by using the switch. BYD said that users can assign special key values to the side keys 5, 6, 7 and 8 in the figure without installing special drivers, and output "←", "↓" and → "respectively, so that the multifunctional mouse is equivalent to a miniature analog keyboard.
Through the multifunctional mouse in the utility model, it can greatly facilitate users to operate on the BIOS interface. For a general reloading system, you need a boot disk, a mirror disk, a USB keyboard and a USB mouse, and you need four USB interfaces, but some computer motherboards don't have that many USB interfaces.
The general BIOS interface can only be operated by keyboard, and some BIOS interfaces can only be operated by mouse and keyboard, which undoubtedly increases the burden of the number of USB interfaces. If the multifunctional output mouse is inserted into PS/2 port, it can even be used without USB interface, which greatly saves the resources of USB interface.
