Description
The present invention relates to a kind of lighting device for keyhole and control method thereof, be applicable to the lockset of motor bike or similar automotive, can be near oneself the vehicle time user under the environment of insufficient light, can make lighting device for keyhole illumination in advance through the mode of induction, and make things convenient for the user to operate key.
Present commercially available automotive, as motor bike, though existing all anti-joyride devices comprise lockset, to opening the lock with the key under the environment of insufficient light, the user need grope to look for key hole voluntarily, and is very inconvenient.
In existing patent, relevant key hole or lockhole lighting engineering, for example announce 142737,143975,165506,194784, No. 356869 etc., these patents are not provided in a side of the little flash light on the key chain in fact, just be provided in a side of the lighting fixture on the door lock, be not located at the lighting fixture on the motor bike; On the other hand; Above-mentioned patent has illumination equipment near only providing the key hole position, as for how illumination just is provided when the user really needs, not open, but, for vehicle such as motor bikes, only just provide illumination during near the key hole of motor bike the user, ability power saving (because of the device on the motor bike must rely on powered battery), and can not become the instrument of luring or helping the burglar to set about, therefore, how the user during near oneself the vehicle, can be through induction mode, and make lighting device for keyhole illumination in advance, and operate key to make things convenient for the user, this has been existing motor bike developer's research and development problem.
The object of the present invention is to provide a kind of easy to use and safe lighting device for keyhole and control method thereof.
For achieving the above object, the present invention takes following technical measures:
A kind of lighting device for keyhole of the present invention comprises: a power supply unit and an illumination equipment; Also comprise:
A control chip, a main switch and an induction installation;
Control chip is connected with main switch, induction installation, power supply unit respectively, and power supply unit also connects illumination equipment.
Wherein, but described induction installation comprises the inductor of one of signals such as an induction vibration beating, photoinduction, PS (Push Switch), contact.
Wherein, described inductor comprises an infrared inductor.
Wherein, described inductor comprises a PS (Push Switch).
Wherein, described inductor is a piezoelectric buzzer.
Wherein, described inductor comprises a touch chip.
The control method of a kind of lighting device for keyhole of the present invention comprises the following steps:
(1) under the normality, whether detects the user, promptly detect the signal of induction installation, promptly continue to detect, as record signal and then carry out step (2) as no signal near key hole;
(2) state of detection main switch is " pass " as main switch, then control lighting device for keyhole and be " opening ", and be " opening " as main switch, then lighting device for keyhole is controlled to be " pass ".
Wherein, also comprise the following steps: when main switch be " opening " state, and when not having any energizing signal such as charging signals, actuating motor, all first closing control chip.
Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows architectural feature of the present invention:
The accompanying drawing simple declaration:
Fig. 1: the diagram of circuit of control method embodiment of the present invention;
Fig. 2: the circuit block diagram of lighting device for keyhole embodiment of the present invention;
Fig. 3,4: the application state scheme drawing of lighting device for keyhole embodiment of the present invention;
Fig. 5: lighting device for keyhole of the present invention utilizes the scheme drawing of photoinduction embodiment;
Fig. 6 A: the button circuit diagram in the lighting device for keyhole induction mode of the present invention;
Fig. 6 B, 6C, 6D represent vibration formula, photoinduction formula and the touch circuit diagram in the induction mode of the present invention respectively.
As shown in Figures 1 and 2, key hole illumination induction installation of the present invention comprises control chip 1, main switch 2, induction installation 3, power supply unit 4 and lighting device for keyhole 5; Control chip 1 is connected with main switch 2, induction installation 3, power supply unit 4 respectively, and power supply unit 4 connects lighting device for keyhole 5 again, and control chip 1 is between main switch 2 and power supply unit 4.
Control method of the present invention comprises the following steps (as Fig. 1):
1, under normal conditions, whether detect the user, promptly detect the signal of induction installation, promptly continue to detect, as record signal and then carry out step 2 as no signal near key hole; 2, detecting the state of main switch 2, be " pass " as the state of main switch 2, and then controlling lighting device for keyhole 5 is " opening " state, is " opening " as the state of main switch 2, and then lighting device for keyhole 5 is controlled to be " pass " state.
Main flow is: control chip 1 normality is in detection main switch 2 and is " opening " or "off" state, when state is " pass ", further detect the signal of induction installation 3, when experiencing the signal of induction installation 3, further detect clean boot voltage again, when clean boot voltage during in the clean boot scope, control chip 1 is just controlled and is made lighting device for keyhole 5 light or light a period of time; The embodiment of the invention can be connected with antitheft circuit in fact again, so sub-process of the present invention comprises: when clean boot voltage during not in the clean boot scope, main switch 2 is at " opening " state, and when not sending any energizing signal (as charging signals, actuating motor, power connection etc.), all first closing control chip 1, certainly, lighting device for keyhole 5 is lighted; These two sub-processes mainly are to prevent to connect unusually (robber's link) and antitheft; In addition, when main switch 2 is in " pass " state, and when not detecting the induced signal (in fact be user leave and do not return by motorcycle as yet) of induction installation 3, and main switch 2 is at " opening " state, and sending any energizing signal (in fact is that the user has returned by motorcycle to control chip 1, and start) time, control chip 1 also just needn't make lighting device for keyhole 5 light certainly.
Shown in Fig. 6 A～D, it is respectively the circuit diagram of different inductor, and among the figure, the inductor 31 in the induction installation 3 is respectively embodiment such as PS (Push Switch), vibration formula, photoinduction formula, contact.
In Fig. 6 A, inductor 31 comprises that a PS (Push Switch) 311 reaches and its illumination equipment that is connected in series mutually 5 (light-emitting diode 310), when PS (Push Switch) 311 was pressed, light-emitting diode 310 was luminous, and PS (Push Switch) can be located at any pushing easily in place's (as handle or panel) on the motor bike.
As (vibration formula) among Fig. 6 B, inductor 31 mainly comprises piezoelectric buzzer 312 amplifier, delay circuit and a light-emitting diode 310, piezoelectric buzzer 312 produces signal when patting signal, makes light-emitting diode 310 luminous through amplification and delay circuit.
