Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Thermo-electric generation wireless mouse as shown in Figure 3, Figure 4, comprise Mouse assembly and thermo-electric generation assembly, described Mouse assembly comprises heat conduction top cap of mouse 1, mouse control mainboard 5, mouse lower cover 6, except above-mentioned parts, a complete mouse also may have other members such as mousebutton 7, roller 8, photoelectric sensor, spin, inductor, wireless signal transceiver, these members belong to prior art, in the utility model, are not described in detail.In addition, along with the fast development of induction technology, on market, there is the induction mouse of roller-less button; although therefore drawn roller 8 and mousebutton 7 in Fig. 1; but it must be noted that, they are not the essential features of this programme, should not limit protection domain of the present utility model.Described thermo-electric generation assembly comprises thermo-electric generation sheet 2, mu balanced circuit, charging control circuit 3 and rechargeable battery 4, heat conduction top cap of mouse 1 contacts with the palm of human body, palmar aspect radian when therefore the outer wall of upper cover 1 should grasp mouse with human body as far as possible approaches, and could receive the palm heat of human body maximum magnitude.Heat conduction top cap of mouse 1 should be made by the good material of heat-conducting effect, is preferably aluminum upper cover, and quality is light, good heat conductivity, and ductility is high, is easy to manufacture.The hot junction face of described thermo-electric generation sheet 2 should be connected with the inwall of heat conduction top cap of mouse 1 and the laminating of trying one's best, and the upper surface of thermo-electric generation sheet 2 should be consistent with the inwall radian of heat conduction top cap of mouse 1, to reach best heat-transfer effect.The voltage that thermo-electric generation sheet produces is undertaken after voltage stabilizing processing by mu balanced circuit, and via charging control circuit 3, to rechargeable battery 4 chargings, described rechargeable battery 4 is 5 power supplies of mouse control mainboard.Rechargeable battery 4 preferably adopts lithium battery, long service life, memory-less effect.
When using thermo-electric generation wireless mouse, if palm is placed on the surface of mouse always, the hot junction face of thermo-electric generation sheet 2 receives palm heat by the conduction of heat conduction top cap of mouse 1, owing to there is the temperature difference in the upper and lower surface of thermo-electric generation sheet 2, thereby generation electromotive force, thereby can directly heat energy be converted into electric energy.But this electromotive force is also unstable, need to control by mu balanced circuit, this example adopts LM780 as the Master control chip of mu balanced circuit, and its output voltage is 6V, and output maximum current is 1A, can change by resistance value in regulating circuit its output valve.After magnitude of voltage is stable, need electrical power storage in lithium battery, due to needs by lithium cell charging to voltage maximum rating, but can not overcharge, so this example employing charge controlling chip MAX1898 charges to lithium battery, prevent over-charge of lithium battery.Concrete charging process can be controlled as follows, when MAX1898 detects voltage in lithium battery lower than 2.5V, carries out trickle charge, and the little pre-charge of 5mA is provided, and when magnitude of voltage reaches 2.9V, carries out total current rapid charge.When cell voltage reaches preset voltage (being generally made as 4.2V), start to carry out constant-voltage charge, charging current reduces simultaneously, and finishing rate is reduced to 0 gradually, and charging process finishes.When electric quantity of lithium battery is sufficient, mouse control plate can adopt the electric energy power supply in lithium battery.The mouse that uses the utility model to provide, as long as can be continuously for mouse charges by people's grasped, without worrying power-off problem, environmental protection be pollution-free.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being comprised of above technical characterictic combination in any.It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
