Description
Technical field
The utility model relates to a kind of rechargeable automobile key, belongs to the key technical field.
Background technology
Along with the automobile key of the coupling of the development of science and technology and automobile also makes great progress, it progressively develops so far wireless remote controlled keys from initial mechanical type key.Remote-control key is to reach the purpose of opening and controlling automobile by electronic technology and radiotechnics combination, and its people that appear as have brought good user to experience, and have satisfied the requirement of people to convenience and comfortableness.But along with the enhancing of the function of automobile key, for satisfying more and more important that the required power supply of its control just becomes, also become the bottleneck of restriction function of automobile key development.
Common automobile remote-control key power unit is to adopt the button cell power supply at present, in order to optimize service time of battery, usually only carries some simple, lower-powered functional modules, and common button cell also only can be kept the service time of six months simultaneously.The loss of battery and discarded after rear chemical contamination process and also become a unavoidable processing difficult problem.
So some automobile vendor begins to attempt replacing original button cell with rechargeable battery at present.But because each manufacturers design is different, often so that have the automobile key of charge function and aspect charging, operate more loaded down with trivial detailsly, and not general, do not take into account the essential function of key yet.Because a kind of convenience, the automobile key that simply has a charge function then have widely prospect of the application.
The utility model content
Technical problem to be solved in the utility model is for the problem that relates in the background technology, proposes a kind of rechargeable automobile key.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of rechargeable automobile key is comprised of the shank of the key box and key bit; Wherein, described key bit is comprised of two metal electrodes and an insulating interlayer, and the outside of described two metal electrodes offers respectively the key line of rabbet joint corresponding with the automobile key hole, and the inboard of described two metal electrodes is connected with the both sides of insulating interlayer respectively; Be provided with power-switching circuit, charging circuit, rechargeable battery in the described the shank of the key box, wherein, the input of described power-switching circuit is connected with two metal electrodes on the key bit respectively, the output of described power-switching circuit is connected with the input of charging circuit, and the output of described charging circuit is connected with rechargeable battery.
Further, rechargeable automobile key of the present utility model, described the shank of the key box also is provided with the additional function circuit, and described additional function circuit comprises interconnective single-chip microcomputer and radio receiving transmitting module.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
The utility model so that key when using, can directly the key built-in rechargeable battery be charged by the metal electrode of the key both sides band line of rabbet joint, not only possessed the basic function of automobile key but also had the ability of real time charging concurrently, and operation is very convenient, has also reached the purpose of environmental protection.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail:
A kind of rechargeable automobile key structure as shown in Figure 1, this key is comprised of the shank of the key box, key bit.
Wherein, key bit is comprised of two metal electrodes and an insulating interlayer, and two metal electrodes are installed in respectively the insulating interlayer both sides, are separated mutually by insulating interlayer not contact.Two one of metal electrodes are anodal, one is negative pole, the inboard of two metal electrodes is bonding with insulating interlayer respectively, and the outside has the line of rabbet joint, and this line of rabbet joint can be realized with automobile the mechanical matching of key to the lock pin in the lower lockhole of dish as the feature of unblanking of plug-in type key.
The various function module circuits that power-switching circuit, charging circuit, rechargeable battery, key are arranged in the shank of the key box.One end of two metal electrodes on the key bit is by the electric current of automotive interior circuit reception from automobile storage battery, the other end connects respectively power-switching circuit, power-switching circuit is the voltage transitions that automobile storage battery provides to be become the voltage of suitable charging, and offers charging circuit; Charging voltage after charging circuit will be changed is charged to the rechargeable battery in the key.In the utility model, the provider of charging voltage can be automobile storage battery, as long as after using key to connect automobile circuit, just can be continual to the rechargeable battery charging, and after the battery charging is complete, then stop the charge protection battery by charging circuit.
Function module circuit in the shank of the key box comprises interconnective single-chip microcomputer and radio receiving transmitting module, mainly is some additional functions of realizing the automobile key chip, such as: automobile remote-control function, password generation and decoding function, music alarm function etc.
Claims (2)
1. a rechargeable automobile key is characterized in that: be comprised of the shank of the key box and key bit; Wherein, described key bit is comprised of two metal electrodes and an insulating interlayer, and the outside of described two metal electrodes offers respectively the key line of rabbet joint corresponding with the automobile key hole, and the inboard of described two metal electrodes is connected with the both sides of insulating interlayer respectively; Be provided with power-switching circuit, charging circuit, rechargeable battery in the described the shank of the key box, wherein, the input of described power-switching circuit is connected with two metal electrodes on the key bit respectively, the output of described power-switching circuit is connected with the input of charging circuit, and the output of described charging circuit is connected with rechargeable battery.
