Abstract
The invention discloses a car key with a positioning function. The car key comprises a key body and an internal battery in the key body. The car key is characterized in that an induction coil and an electric control switch connected onto the induction coil are arranged in the key body; the electric control switch is connected with a buzzer and the internal battery; the car key also comprises a coupling coil which is externally arranged and matched with the induction coil; after inducing the signal of the coupling coil, the induction coil is combined with the electric control switch. According to the car key disclosed by the invention, the induction coil and the buzzer are arranged, so the location of the car key can be conveniently obtained.
Description
Technical field
The present invention relates to automobile key.
Background technology
Existing automobile key is all put everywhere usually, cannot find sometimes.
Summary of the invention
The object of the invention is to, for problem existing in prior art, provide a kind of car key with positioning function easy to use.
Technical scheme of the present invention is as follows:
Have a car key for positioning function, key body, the internal battery in key body, is characterized in that: in key body, have induction coil, and is connected to the electric-controlled switch on induction coil, and electric-controlled switch connects buzzer and internal battery; Also comprise the external coupling coil coordinated with described induction coil; Induction coil senses after the signal of coupling coil together with electric-controlled switch.
Preferably, be connected on battery power with described coupling coil.
Compared with prior art, the present invention arranges recipient and buzzer on car key, can know the position at car key place easily.
Accompanying drawing illustrates:
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with test example and detailed description of the invention, the present invention is described in further detail.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following embodiment, all technology realized based on content of the present invention all belong to scope of the present invention.
Have the car key of positioning function as Fig. 1 is a kind of, key body 1, have internal battery 5 and induction coil 2 in key body 1, and be connected to the electric-controlled switch 4 on induction coil 2, electric-controlled switch 4 is arranged between internal battery and buzzer 3; Also comprise the external coupling coil coordinated with described induction coil; Induction coil senses after the signal of coupling coil together with electric-controlled switch.Be connected on battery power with described coupling coil.When finding car key, can hold the transmitting terminal that coupling coil is housed and look about, when coupling coil and induction coil are in mutual induction distance, induction coil is charged, opens electric-controlled switch, and buzzer to be powered sounding by internal battery, finds automobile key.
