And when torsionspring 230 is twisted and is contracted to be close to tapered end body 210, the second electric wire L2 can be with
Torsionspring 230 is electrically connected with, namely the second electric wire L2 can be electrically connected to the by torsionspring 230
One electric wire L1.Now, the second electric wire L2, after receiving reference voltage VR, can provide startup accordingly
Signal SST is to theft-proofing control circuit 115.Wherein, reference voltage VR can be free voltage, such as
System voltage VDD or ground voltage GND.
Bidirectional final switch SWD is configured on torsionspring 230, and detects the first pull bar connector
The rotation direction of 240, to provide door contact interrupter signal SDS to theft-proofing control circuit 115 accordingly.Lift
For example, when the first pull bar connector 240 is by pressing bidirectional final switch SWD on the left of diagram, table
Showing that car door is powered on, therefore door contact interrupter signal SDS is to represent that car door is unlocked；When the first pull bar connects
Fitting 240, by when pressing bidirectional final switch SWD on the right side of diagram, represents that car door is powered on, therefore
Door contact interrupter signal SDS is to represent that car door is closed.
In embodiment of the present utility model, door contact interrupter signal SDS can be single signal or by multiple
Signal is formed.When door contact interrupter signal SDS is single signal, car door can be represented by different voltages
It is opened or closed, such as system voltage VDD or ground voltage GND；As door contact interrupter signal SDS
By multiple signals formed time, can represent that car door is opened or closed by the enable of unlike signal.
Fig. 3 is based on the car door tapered end of another embodiment of this utility model and shows with the structure rotating testing circuit
It is intended to.Refer to Fig. 2 and Fig. 3, the most same or similar element uses same or similar label.At this
In embodiment, rotating testing circuit 113b and be approximately identical to rotate testing circuit 113a, it is a difference in that
