Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Numeral in figure: 1, car key; 2, charging terminal; 3, charging device; 4, charging module; 5, control module; 6, charging receiving unit; 7, rechargeable battery.
Embodiment
To illustrate below in conjunction with accompanying drawing and embodiment further illustrates the utility model.
As shown in Figure 1, there is provided in a kind of car to the device of car key charging, comprise car key 1, charging terminal 2, charging device 3, described car key 1 provides electric energy by described charging terminal 2, described charging device 3 charges to described charging terminal 2, and described charging device 3 is arranged in car by ignition switch, comprises charging module 4 and the control module 5 of electrical connection, described charging terminal 2 is arranged in described car key 1, and described charging terminal 2 comprises charging receiving unit 6 and the rechargeable battery 7 of electrical connection.
As shown in Figure 1, the electric flux that described control module 5 controls charging device 3 starts or stops being transferred to charging receiving unit 6 to charge.
As shown in Figure 1, whether described charging device 3 energy inspection vehicle key 1 is close, and it provides electric energy by automobile.
As shown in Figure 1, described charging device 3 is communicated with described charging receiving unit 6 by NFC technique.Described charging receiving unit 6 charges to described rechargeable battery 7.
As shown in Figure 1, car key 1 provides electric energy by charging terminal 2, and when charging device 3 normal power supply, charging device 3 charges just automatically to charging terminal 2, and now car key 1 can normal power supply.
Once automobile is powered to charging device, when car key to be placed on charging device or near charging device, charging device automatically by energy transfer to car key.
In the present embodiment, adopt one can the charging device of power taking in automobile, work as automobile starting, the normal power taking of charging device, when car key is placed on charging device or near charging device, control module in charging device can control charging module by energy transfer to the charging receiving unit in charging terminal, and charging device is communicated with charging receiving unit by NFC technique.Charging receiving unit uses the electric flux received to charge to rechargeable battery.Once rechargeable battery electricity is full of, charging terminal can send a command to the control module in charging device, control module in charging device receives the order that electricity is full of, control module can control charging module and stop electric energy transmitting to the charging receiving unit in charging terminal, and last charging receiving unit stops charging to rechargeable battery.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
