Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
Fig. 4 shows the structural representation of the described contactless charging device in the utility model.As shown in Figure 4, described contactless charging device comprises module base 1 and charging part 14, and described charging part 14 is arranged on the described module base 1.
Described module base 1 comprises the bottom 2 and the loam cake 4 that can fasten, and is provided with charging socket 3, coil 7, depression bar 8, battery lead plate 9 and switch 10 between described bottom 2 and loam cake 4.Described coil provides induction electric energy for described charging part.
Wherein, described charging socket is electrically connected with described circuit board, and described circuit board is electrically connected with coil, so that the induced current of charging usefulness is provided for described charging part 14.
Described depression bar 8 is mounted slidably on described loam cake 4, and a distal process of depression bar 8 is for the external table of described loam cake 4, its other end and switch 10 Elastic Contact that are installed on the described battery lead plate 9.Preferably, described switch is a touch-switch.
Preferably, a side of described coil also is provided with coil pressing plate 5.
Preferably, inner surface one side at described loam cake 4 also is provided with first magnet 6 that is used to attract described charging part 14.
Described charging part 14 comprises base 11, is arranged on second magnet 12 on the base 11, and described charging part 14 also comprises accumulation of energy portion 13, and preferably, described accumulation of energy portion is a rechargeable battery.
Also be provided with the charge controller (not shown) in the described charging part 14, the induced current that described charge controller is controlled described coil 7 that described charging part 14 senses to be provided is 13 chargings of described accumulation of energy portion.
Preferably, described contactless charging device is installed in the lamp module.
The course of work of described contactless charging device is as follows:
When needs charge, described charging part 14 is placed on the loam cake place of described module base 1, at this moment, second magnet in the charging part and first magnet in the module base attract each other, so, under the effect of the gravity of described attraction and charging part 14, charging part remains on the described module base reliably, simultaneously, depression bar 8 on the module base 1 is depressed, thereby trigger described switch 10 and provide a triggering signal to described coil 7 power supplies to the circuit board 9 of described module base 1, after described circuit board 9 was received this triggering signal, the electric energy that described charging socket 3 is provided outputed to described coil 7.Next, the charge controller in the described charging part 14 is sensed the induced current from described coil 7, and the energy that it is sensed is stored in the described accumulation of energy portion 13.When not needing to charge, described charging part 14 is taken away from described module base, at this moment, thereby the depression bar on the module base no longer the pressurized elastic recovery to initial state, so that described switch sends the triggering signal that stops to charge to described circuit board, so circuit board stops to coil power supply.
Contactless charging device described in the utility model is by being arranged on the magnet that can attract each other on charging part and the module base, make the two more closely to combine, have simple in structure, dependable performance, fail safe is good, cost is low, the contact reliable characteristics.
The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
