Description
Technical field
The utility model belongs to the keyboard of electronic equipment, is specifically related to a kind of isolated island formula power generation keyboard and electronic equipment thereof.
Background technology
Now along with the development of technology, the electronic equipments such as notebook are subject to the restriction of battery capacity service time when out using, if have power supply also by connecting power supply to increase service time, if but it is inconvenient to connect power supply, may directly affect work and study progress and efficiency, visible, the size of battery capacity badly influences the service time of electronic equipment.
If increasing battery capacity, need battery volume to become large simultaneously, mechanism design is had a significant impact.Meanwhile, due to the increase of electronic equipment volume and weight, occupy very large space, carrying or increasing a lot of inconvenience in use procedure, when causing terminal use to use, susceptibility is bad, affects product quality.
How when not affected by environment, neither strengthen battery volume, the equipment use time can be made again to increase, become a bottleneck with the contradiction of battery capacity in thin, the light evolution of solution current electronic device.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of isolated island formula power generation keyboard, utilize electromagnetic induction principle, in electronic equipment use procedure, the relative motion of the equal generating coil cutting magnetic line of upper and lower motion of keycap, and the alternating current of generation to be converted to direct current by AC-DC conversion equipment be battery charging, increase battery electric quantity, increase service time; Reasonable in design, convenient and swift.
For achieving the above object, the utility model by the following technical solutions:
A kind of isolated island formula power generation keyboard, comprise keycap and keyboard base, described keycap is magnetic keycap, and described keyboard base arranges closed power coil, and described magnetic keycap is arranged on the inside of closed power coil, the magnetic line of force of described power coil cutting magnetic keycap.
Further, described power coil is arranged on the keyboard base surrounding whole keycap area.
Further, described power coil is arranged on the keyboard base around some keycaps.
Further, described power coil is arranged on the keyboard base around arbitrary keycap.
Further, described multiple be connected or non-conterminous keycap be provided with magnetic material.
Further, the output of described power coil connects AC-DC conversion equipment.
Further, described AC-DC conversion equipment comprises AC-DC conversion wafer or rectifier.
Further, described AC-DC conversion equipment adopts AC-DC to change wafer, and this AC-DC changes the output that wafer is set in power coil.
Further, magnetic material is provided with on the downside of described keycap surrounding.
A kind of electronic equipment, comprise above-mentioned isolated island formula power generation keyboard, described AC-DC conversion equipment is communicated with device battery.
The utility model compared with prior art has the following advantages:
1) the utility model keycap adopts magnetic keycap, arranges a closing coil at keyboard frame, and coil connects AC-DC conversion equipment and is communicated with device battery, so, does not additionally increase space; Use magnetic material to make by the downside of keycap surrounding, when use keyboard, keycap moves up and down, the relative motion of generating coil cutting magnetic line, the alternating current of generation; By AC-DC conversion wafer or rectifier, the alternating current of generation is converted to direct current, battery is charged.
2) the utility model is when using electronic equipment keyboard, moving up and down by keycap, can realize charging to battery, with the problem of the contradiction of battery capacity in effective solution electronic apparatus thin, light evolution, when using keyboard, automatic charging increases service time, convenient and swift, and it is convenient to control, improving product quality, improves user's use sense and is subject to.
3) the utility model reasonable in design, does not need additionally to take the space on height, easily realizes, good stability.
4) the utility model is applicable to various types of keyboard, applied range, and applicability is good.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As shown in Figure 1,2 and 3, the present embodiment comprises keycap 1, scissor 5 and keyboard base 3, each keycap inside casing of described keyboard base, closed power coil is set, some keycaps are arranged on the inside casing region of keyboard base 3, magnetic material is provided with, by scissor 5 cushioning supportive of its correspondence on keyboard base 3 on the downside of the surrounding of described keycap 1.Wherein, scissor 5 can be other supporting constructions.
During installation, the output of power coil 2 is changed wafer 4 by AC-DC and is connected with device battery.
As shown in Figure 4, the output of power coil 2 is communicated with device battery.Power coil 2 is formed with the closed-loop path of power supply, magnetic keycap 1 carry out up or down both direction motion process in, power coil 2 all can cutting magnetic line, produce alternating current, then change wafer 4 i.e. convertible output direct current by AC-DC, battery is charged, even if when battery does not have electric be also closed-loop path, under the idle state of electronic equipment, pressing keyboard equally can charge to battery by generation current.So, when use keyboard, all can charge to battery by knocking arbitrary keycap.
Embodiment 2
The difference of the present embodiment and embodiment 1 is, a described coil can around two or more keycap, as shown in Figure 5, as long as namely magnetic keycap is arranged on the inside of closed power coil, make described power coil can cut the magnetic line of force generation current of magnetic keycap.
The utility model above-described embodiment is only the good execution mode of this patent, the structure that all employing the technical program describes, feature and the change in its spiritual principle, modifies the protection range all belonging to this patent.
