Abstract
The invention discloses a charging type automobile key. The charging type automobile key consists of a key handle box and a key bit, wherein the key bit consists of two metal electrodes and an insulating interlayer; outer sides of the two metal electrodes are respectively provided with key groove lines corresponding to automobile key holes; the inner sides of the two metal electrodes are respectively connected with the two sides of the insulating interlayers; the key handle box is internally provided with a power conversion circuit, a charging circuit and a charging battery; the input end of the power conversion circuit is respectively connected with two metal electrodes on the key bit, and the output of the power conversion circuit is connected with the input end of the charging circuit; and the output end of the charging circuit is connected with the charging battery. The charging type automobile key disclosed by the invention has the advantages that the key can be directly charged while being used, the basic function and the real-time capability of the automobile key are achieved, great convenience is brought for operation, and the purpose of protecting the environment is also achieved.
Description
Technical field
The present invention relates to a kind of rechargeable automobile key, belong to the key technical field.
Background technology
Along with the automobile key of the coupling of development of science and technology and automobile has also had very big progress, it progressively develops wireless remote controlled keys so far from initial mechanical type key.Remote-control key is the purpose that combines to reach unlatching and Control of Automobile through electronic technology and radiotechnics, and its people that appear as have brought good user to experience, and have satisfied the requirement of people to convenience and comfortableness.But,, also become the bottleneck of restriction automobile key function development for satisfying more and more important that the required power supply of its control just becomes along with the enhancing of the function of automobile key.
At present common automobile remote-control key power unit is to adopt the button cell power supply, in order to optimize battery service time, only carries some simple, lower-powered functional modules usually, and common button cell also only can be kept the service time of six months simultaneously.The loss of battery with discarded after back chemical contamination handle and also become a unavoidable processing difficult problem.
So some automobile vendor begins to attempt using rechargeable battery to replace original button cell at present.But because each manufacturers design is different, it is more loaded down with trivial details often to make the automobile key with charge function aspect charging, operate, and not general, does not also take into account the essential function of key.Because a kind of convenience, the automobile key that simply has a charge function then have and use prospect widely.
Summary of the invention
Technical problem to be solved by this invention is to the problem that relates in the background technology, proposes a kind of rechargeable automobile key.
The present invention adopts following technical scheme for solving the problems of the technologies described above:
A kind of rechargeable automobile key is made up of the shank of the key box and key bit; Wherein, said key bit is made up of two metal electrodes and an insulating interlayer, and the outside of said two metal electrodes offers respectively and the corresponding key line of rabbet joint in automobile key hole, and the inboard of said 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 said the shank of the key box; Wherein, The input of said power-switching circuit respectively with key bit on two metal electrodes be connected; The output of said power-switching circuit is connected with the input of charging circuit, and the output of said charging circuit is connected with rechargeable battery.
Further, rechargeable automobile key of the present invention, said the shank of the key box also is provided with the additional function circuit, and said additional function circuit comprises interconnective single-chip microcomputer and radio receiving transmitting module.
The present invention adopts above technical scheme compared with prior art, has following technique effect:
The invention enables key when using; Can directly the key built-in rechargeable battery be charged through the metal electrode of key both sides trough of belt line; 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 a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is done further detailed description:
A kind of rechargeable automobile key structure is as shown in Figure 1, and this key is made up of the shank of the key box, key bit.
Wherein, key bit is made up of two metal electrodes and an insulating interlayer, and two metal electrodes are installed in the insulating interlayer both sides respectively, are separated each other 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 the machinery coupling of key with automobile lock pin in the lockhole under dish as the characteristic 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 receives the electric current from automobile storage battery through the automotive interior circuit; The other end connects power-switching circuit respectively; 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 present invention, the provider of charging voltage can be an automobile storage battery, as long as after using key to connect automobile circuit, just can be continual to the rechargeable battery charging, and, battery charge then stops the charge protection battery after finishing through 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 made up of the shank of the key box and key bit; Wherein, said key bit is made up of two metal electrodes and an insulating interlayer, and the outside of said two metal electrodes offers respectively and the corresponding key line of rabbet joint in automobile key hole, and the inboard of said 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 said the shank of the key box; Wherein, The input of said power-switching circuit respectively with key bit on two metal electrodes be connected; The output of said power-switching circuit is connected with the input of charging circuit, and the output of said charging circuit is connected with rechargeable battery.
2. a kind of rechargeable automobile key according to claim 1 is characterized in that: said the shank of the key box also is provided with the additional function circuit, and said additional function circuit comprises interconnective single-chip microcomputer and radio receiving transmitting module.
