Wireless power transmission mouse

Abstract

The invention discloses a wireless power transmission mouse which comprises a wireless power transmission device. The wireless power transmission device comprises an alternating-current inverter, a wireless electric transmission device and a rectifier filter voltage stabilizer. An input end of the alternating-current inverter is connected with a power cable of a USB (universal serial bus) or a +5V power supply output by other devices, and an output end of the alternating-current inverter is connected with an input end of the wireless electric transmission device. An output end of the wireless electric transmission device is connected with an input end of the rectifier filter voltage stabilizer, and an output end of the rectifier filter voltage stabilizer is connected with the wireless power transmission mouse and powers the same.

Description

Technical field [0001] The invention relates to a wireless mouse that receives electricity in a non-contact mode, that is, a wireless mode. Background technique [0002] With the popularity of consumer computers, the development of the mouse has become more and more rapid, from the early mechanical wheel mouse to the current mainstream optical mouse to the high-end laser mouse and blue shadow mouse. [0003] At present, the most widely used and best effect is the wired mouse, but this kind of mouse needs to provide power and transmit signals through the line, which affects the cleanliness of the desk surface, and also affects the comfort during operation, and people are more concerned about office conditions and operating comfort. With increasing requirements, wired mice are increasingly unable to meet people's needs. Therefore, the popularity of wireless mice has increased rapidly in recent years. However, the wireless mouse needs battery power supply, which not only increases th...

Problems solved by technology

[0003] At present, the most widely used and the best effect is the wired mouse, but this kind of mouse needs to provide power and transmit signals through the line, which affects the cleanliness of the office desktop and the comfort during operation, and people's expectations for office conditions and operating comfort The requirements are increasing day by day, and wired mice cannot meet people's needs more and more. Therefore, the popularity of wireless mice has increased rapidly in recent years.

However, the wireless mouse needs a battery to supply power, which not only increases the weight of the mouse and affects the feel of the mouse, but also when the battery energy is exhausted, the mouse cannot continue to work, and a new battery must be replaced, which may delay some work. The treatment is also a major problem in environmental protection today.

[0004] Before this invention application, someone has proposed a self-charging wireless mouse (authorized announcement number: CN201892925U), which uses piezoelectric ceramics to convert the clicks on the operation buttons into electrical energy to charge the mouse, but the electrical energy generated by piezoelectric ceramics is very weak and difficult to charge. Guaranteed to provide stable power for the normal use of the mouse, and the mouse still uses batteries, and there is still the problem of battery disposal; some people have also proposed an optical mouse with its own power generation device (authorization announcement number: CN201780562U), which is set in the mouse to contain A power generating device comprising a driving ball, a generator and at least one rotating shaft. The driving ball is in contact with the rotating shaft, and the rotating shaft is meshed with the power shaft of the generator. The driving ball is in contact with the desktop, and is driven to roll when the mouse moves, thereby driving the generator To generate electricity, a rectifier circuit is used to convert the alternating current output by the generator into direct current to charge the battery, but the mechanical device is relatively complicated, and it is inconvenient to arrange in the small space inside the mouse, and a drive that is in contact with the desktop is set in the photoelectric mouse. The ball will seriously affect the accuracy and comfort of mouse operation, and there is still the problem of battery disposal; some people have also proposed a mutual induction rechargeable wireless optical mouse (authorized announcement number: CN2821688Y), which is a wireless optical mouse and a wireless optical mouse invented by it. Mouse pad, the mouse pad is provided with a primary PCB board and a primary coil, and the mouse body is provided with a secondary PCB board and a secondary coil. When the wireless mouse works on or near the mouse pad, it provides power to the mouse through the principle of mutual induction, but this is practical The new type requires the mouse pad to have wired power input or use batteries. Not only does it not realize true wireless power supply, but also must use a mouse pad. Now the new technology of wireless mouse, laser mouse and blue shadow mouse, has already freed the mouse from the shackles of the mouse pad. Works well on almost any flat surface

[0005] Therefore there is an urgent need for a wireless mouse with simple structure, low manufacturing cost, stable work and really no need for batteries, so that people can get rid of the shackles of mouse wires and batteries, and also solve the frequent replacement of batteries and environmental pollution problems. report
