Abstract
The utility model discloses a self-generating electric wireless keyboard. The self-generating electric wireless keyboard is characterized by comprising a keycap (1), a keyboard outer shell (2), a key pillar (3), a spring (4), polyvinylidene fluoride (PVDF) piezoelectric films (5), an electronic contact piece (6), an evaporation metal electrode (7), an energy storage circuit board (8) and a small storage battery (9). The PVDF piezoelectric films (5) are divided into multiple layers to be arranged between the lower end of the key pillar (3) and the electronic contact piece (6). The evaporation metal electrode (7) is connected with the PVDF piezoelectric films (5). An evaporation electrode metal layer technology is utilized to lead out an electrode wire, and the energy storage circuit board (8) is connected on the electrode wire. The small storage battery (9) is connected with the energy storage circuit board (8). A PVDF piezoelectric technology is utilized to achieve self-generating electricity of a wireless keyboard, defects of big power consumption and frequently-changing of the battery of a wireless keyboard are overcome, and simultaneously, wasted batteries causing the environmental pollution is effectively reduced.
Description
Technical field
The utility model relates to a kind of self-generating wireless keyboard, specifically relates to the novel self-generating wireless keyboard of a kind of PVDF of employing piezo technology and electrode evaporation metal level technology.
Background technology
This drawback that present Wireless Keyboard all exists power consumption large shortcoming, especially gamepad is more obvious.Generally, just need to change one-shot battery for Wireless Keyboard every other month, and change continually the use cost that battery has increased the consumer greatly, also cause simultaneously the pollution of refuse battery to environment.In the situation that the Wireless Keyboard electric weight is low, button sensitivity meeting reduces greatly, often causes the not reaction of maloperation even Wireless Keyboard.This shows, existing Wireless Keyboard has brought a lot of troubles to us, and the use of a large amount of batteries has also caused pollution to environment.
Because we always exist constantly in using the Wireless Keyboard process and press, therefore produced very frequently discontinuity pressure energy, we can convert this part discontinuity pressure energy to power storage fully in the small battery of Wireless Keyboard inside, continue for Wireless Keyboard, however the equal unrealized this point of traditional Wireless Keyboard.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, and the self-generating wireless keyboard of a kind of PVDF of employing piezo technology and electrode evaporation metal level technology is provided.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
A kind of self-generating wireless keyboard, it is characterized in that: comprise keycap, keyboard case, key post, spring, PVDF piezoelectric membrane, electronics contact, evaporation metal electrode, tank circuit plate, small battery, a described PVDF piezoelectric membrane minute multilayer is installed between key post lower end and the electronics contact, the evaporation metal electrode is connected with the PVDF piezoelectric membrane, utilize electrode evaporation metal level technology extraction electrode wire, the tank circuit plate is connected on the described electrode cable, and described small battery is connected with the tank circuit plate.
Rectification circuit on the described tank circuit plate can be three-phase, single-phase or heterogeneous controlled rectification circuit.
Compared with prior art, the beneficial effects of the utility model are:
The intermittent pressure energy that produces during with button by the PVDF piezo technology converts electric energy to, and it is inner to be stored in the small battery of Wireless Keyboard inside, thereby has realized the lasting use of Wireless Keyboard.The utility model improved Wireless Keyboard power consumption large, change frequently shortcoming of battery, also reduced the pollution of old and useless battery to environment simultaneously.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the utility model comprises keycap 1, keyboard case 2, key post 3, spring 4, PVDF piezoelectric membrane 5, electronics contact 6, evaporation metal electrode 7, tank circuit plate 8, small battery 9,5 minutes multilayers of described PVDF piezoelectric membrane are installed between key post 3 lower ends and the electronics contact 6, its thickness is 50 μ m, frequency response is wide, dynamic range is large, power electricity converting sensitivity is high, mechanical properties strength is high, acoustic impedance is easily mated, lightweight, softness is not crisp, shock-resistant, can have more and need to make arbitrarily shape, and can be by 5 series connection of multilayer PVDF piezoelectric membrane are improved its generating efficiency.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
