Abstract

The utility model provides a wireless mouse inducing type power supply device. The utility model is characterized in that an electromagnetic wave radiating coil is embedded in the inner cloth of a mouse pad, and an inducting coil is arranged in a proper position inside a mouse body, and then the electromagnetic wave generated by the radiating coil in the mouse pad can be connected crossly to the inducting coil inside the mouse body to generate an electromotive force, which can penetrate the parallel resonance of the inducting coil and a capacitor to charge a charging capacitor directly through the passage of a rectifier diode, and simultaneously can provide power supply to a wireless transmission circuit preset in the mouse; then without an additional battery, the wireless mouse can be provided with needed power supply directly; and a charging battery can be additionally arranged in the mouse. When being in use, the utility model can provide the power supply on one hand, and can charge the charging battery on the other hand, and ensure that the mouse can achieve multifold utilization effectiveness.

Description

The wireless mouse inductive power-supply supply device

Technical field

The utility model relates to a kind of wireless mouse inductive power-supply supply device.

Background technology

General wireless mouse, the supply of its power supply can be divided into two kinds: one for the inner dry cell that uses, so that the wireless signal radiating circuit to be provided; Another charges on cradle, as the charging situation of mobile phone in advance for using rechargeable battery; Following shortcoming is so arranged on it:

1, the inner dry cell that uses of mouse, owing to use a period of time, the electric power of this battery will produce the power shortage phenomenon; the dry cell that must change the outfit often, quite inconvenience in the use is as in use; under power shortage, there is not reserve battery again, work is paused.

2, mouse is if use rechargeable battery, and it certainly will provide a cradle in advance, to rechargable battery in charging at ordinary times; And the charging matching structure between this cradle and mouse, then as mobile phone, this mouse outer surface is provided with two Metal Contact sheets, cooperate two power contacting plates on the cradle again, place on the cradle through mouse, and make the power contacting plate on mouse Metal Contact sheet and the cradle touch, in order to do charging action; Right this contact chip easily produces the loose contact facts if put badly because of mouse, and this can obtain to confirm in mobile phone charging problem, moreover, on the Metal Contact sheet, easily because of long-time use, and the sticking together of generation dirt, its charging effect is more had a greatly reduced quality.

Summary of the invention

The purpose of this utility model provides a kind of wireless mouse inductive power-supply supply device; Be to use an electromagnetic wave radiation coil to be embedded in the mouse pad, and power, to send the magnetic wave signal; And, then establish an induction coil in mouse body, and and cooperate a charging circuit, supply with the existing wireless transmission signal circuit of mouse to export a power supply, the electric power that makes this wireless mouse reaches easy-to-use Practical Benefit person continually.

Another purpose of the present utility model provides a kind of wireless mouse inductive power-supply supply device; The charging circuit rear end of this wireless mouse can connect a rechargable battery, makes this wireless mouse in using, and simultaneously rechargable battery is charged, with the convenient utilization benefit that provides this wireless mouse increase to carry.

Another purpose of the present utility model provides a kind of wireless mouse inductive power-supply supply device; This wireless mouse can be provided with a cradle in addition, be provided with the flush type coil in the circuit board of mat cradle end face, make its magnetic wave that produces, directly the induction coil of commissure in wireless mouse, to produce an electromotive force, also make resonance, and, simultaneously rechargeable battery is charged via the diode path via the capacitor of parallel connection, in order to do being provided in not use a computer down, with the collocation of a cradle, and obtain the charge function of wireless mouse, so that the convenience when carrying to be provided.

Above-mentioned purpose of the present utility model is achieved in that a kind of wireless mouse inductive power-supply supply device, is made up of a wireless mouse and a mouse pad; Also comprise: a wireless mouse; An induction coil is established in its inner bottom appropriate location, and in parallel with the capacitor of a power supply circuit, forms a resonant circuit in parallel, via the path of diode, and is connected to charging capacitor, to form an inductive power-supply supply circuit; One mouse pad; Be that coil is embedded in the mouse pad, maybe this coil application of printed circuit mode formed, and this coil is met a power line W, with the input power supply.

For being convenient to further to understand structure of the present utility model, feature, effect and practical purpose thereof, the utility model is elaborated below in conjunction with accompanying drawing.

Embodiment

See also Fig. 1, Fig. 2 and shown in Figure 3: the inner bottom appropriate location of this wireless mouse 1, an if induction coil L2, and it is in parallel with the capacitor C1 of a power supply circuit PC, form a resonant circuit in parallel,, and be connected to charging capacitor C2 in path via diode D, to form an inductive power-supply supply circuit, and the two ends of this charging capacitor C2, then export one preset and with the operating voltage of existing wireless signal radiating circuit coupling, through the sub-P output of power connection end; And this mouse pad 2 is that coil L 1 is embedded in the mouse pad 2, and this coil L2 is met a power line W, to supply with power supply; Please cooperate shown in Figure 4 again: when wireless mouse 1 places on the mouse pad 2, but and the coil L2 application of printed circuit modes in this mouse pad 2 form; Coil L1 when power supply input mouse pad 2, to produce a magnetic wave, this magnetic wave signal is then received by the induction coil L2 in the wireless mouse 1, then this induction coil L2 promptly produces an electromotive force, and form parallel resonance with the capacitor C1 of power supply circuit PC, this signal is then via diode D path, and charging capacitor C2 is charged, simultaneously output power to wireless mouse 1 inside existing wireless signal radiating circuit plate, make wireless mouse make remote control be used in the operation of computer, in order to do the electric power that makes wireless mouse continuously, to avoid that power shortage or outage phenomenon take place in the wireless mouse use; Moreover, between charging capacitor C2, can a rechargeable battery B in parallel, make wireless mouse 1 in using, can provide charge function with fashion, with carrying of convenient mouse, use and can be applicable to not have this mouse pad of burying coil apparatus underground 2.

Please consult Fig. 2 and shown in Figure 5 again: electric supply installation of the present utility model, one cradle 3 can be provided, be equiped with a similar printed circuit board (PCB) 2 ' that is embedded with the mouse pad of coil on it, then then can directly place wireless mouse 1 of the present utility model thereon, can charge to rechargeable battery B, the convenience of carrying to be provided and not to have this mouse pad of burying coil apparatus underground 2 and use.
