Further include button 50 and processing module 60 in some embodiments of the invention with reference to shown in Fig. 3 to Fig. 4,
In, button 50 is set on the shell 10；Processing module 60 be set in the shell 10 and with the button 50 and power supply
40 are electrically connected, and the signal to be triggered according to the button 50 controls the power supply 40 and is turned on and off.
That is, the button 50 can be operated for user, control signal is generated with triggering, processing module 60 receives
After the control signal, it is turned on and off according to the control signal control power supply 40, it is corresponding, when power supply 40 is opened, then LED light
Source 30 is opened, and when power supply 40 is closed, corresponding, LED light source 30 is closed, in this way, the switch of the LED light source 30 may be implemented
Control in order to which user opens the LED light source 30 when needed, and controls the LED light by the button 50 when not needed
Source 30 is closed.
It illustratively,, certainly, should in order to which user operates as shown in figure 3, button 50 is set to the rear end of shell 10
Button 50 can also be arranged as required in the position that other are operated convenient for user on shell 10.
Advantageous, which may be used self-locking button, in this way, when user presses the button 50 for the first time, this is pressed
Key 50 is connected and is kept, i.e. self-locking, and when pressing the button 50 for the second time, which disconnects and bounce, in this way, using operation
It is convenient.
It is, of course, understood that the button 50 can also use other press-key structures in the prior art.
With reference to shown in Fig. 4, in some embodiments of the invention, processing module 60 is electrically connected with the OBD connectors 20,
Detecting the connection status between the OBD connectors 20 and vehicle diagnosis interface, and when detect the OBD connectors 20 with
When vehicle diagnosis interface connects, the closing of the power supply 40 is controlled.
In general, OBD contact pins 201 in OBD connectors 20 are more, for example, standard 16 needles, corresponding, vehicle diagnosis connects
Pin hole in mouthful is also 16 holes.After OBD connectors 20 and vehicle diagnosis interface grafting, each OBD contact pins in OBD connectors 20
201 grafting corresponding with each pin hole in vehicle diagnosis interface, then at least partly OBD contact pins 201 generate signal in grafting.Example
Such as the 4th pin and the 16th pin, wherein for vehicle body, the 16th pin is positive voltage, the 4th pin and the 16th pin to the 4th pin
With in vehicle diagnosis interface the 4th pin hole and the 16th pin hole grafting after, power supply 40 can be obtained from automobile power source 40, it is corresponding,
4th pin and the 16th pin generate signal, at this point, the signal that processing module 60 can be generated according to the 4th pin and the 16th pin
Judge that OBD connectors 20 have connected with vehicle diagnosis interface.
And when processing module 60 detects that OBD connectors 20 are connect with vehicle diagnosis interface, processing module 60 can export
Signal is controlled to LED light source 30, to control the closing of power supply 40, corresponding, LED light source 30 is closed.
That is, user is when in use, LED light source 30 can be opened, is illuminated using LED light source 30, in turn
Facilitate and OBD connectors 20 are inserted into vehicle diagnosis interface.When OBD connectors 20 are inserted into vehicle diagnosis interface, OBD connectors 20 produce
Raw signal, the signal detection OBD connectors 20 that processing module 60 is generated according to OBD connectors 20 have connected with vehicle diagnosis interface, into
And control the closing of LED light source 30.
Due to working as after OBD connectors 20 are inserted into vehicle diagnosis interface, LED light source 30 is no longer required, still, at this point,
LED light source 30 is located in vehicle diagnosis interface, and light will not substantially expose to outside, so, user is difficult to find LED
Whether light source 30 has been switched off, and once forgets that the LED light source 30 is turned off manually, then the LED light source 30 can be caused to be constantly in
Illuminating state, and then electric energy is wasted, meanwhile, also it be easy to cause the damage of LED light source 30.In the present embodiment, pass through processing module 60
LED light source 30 is actively closed after OBD connectors 20 are connect with vehicle diagnosis interface, and then can be to avoid the generation of the above problem.
The present invention other embodiments in, processing module 60 be additionally operable to when detect the OBD connectors 20 not with
When the vehicle diagnosis interface connection, controls the power supply 40 and stay open.
That is, if OBD connectors 20 not with the vehicle diagnosis interface successful connection, processing module 60 control
Power supply 40 is always maintained at opening, corresponding so that the holding of LED light source 30 is always on, and then user is facilitated to be inserted into OBD connectors 20
Vehicle diagnosis interface, in this way, its is more convenient to use, more hommization.
