In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," and the like are used in the indicated orientations and positional relationships based on the drawings for convenience in describing and simplifying the description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the invention.

In the present invention, unless otherwise specifically stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; the connection can be mechanical connection, electrical connection or communication connection; either directly or indirectly through intervening media, either internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Example 1: the utility model provides an electric motor car battery burglar alarm that key was opened and close, including starting and stopping mechanism and alarm mechanism, alarm mechanism is including setting up permanent magnet 2 in the battery and setting up electromagnet 1 in electric motor car frame, power 7 and audible-visual annunciator 6, the both ends of electromagnet 1 are equipped with perpendicular to electric motor car shell place planar insulating track 3, insulating track 3 is kept away from electric motor car shell place planar one end and is equipped with the shrink haulage rope 4 of connection on electromagnet 1, permanent magnet 2 and 1 heteropolar dislocation of electromagnet set up relatively, the intercommunication has the wire 5 of connection keeping away from shrink haulage rope 4 one end at insulating track 3 on audible-visual annunciator 6, starting and stopping mechanism is including connecting the circuit of opening and close on electromagnet 1, the intercommunication has rotary switch in the circuit of opening and close, the rotary switch transmission is connected on electric. When the battery of the electric vehicle is locked, the rotary switch is reset, the on-off circuit forms a passage to electrify the electromagnet 1, because the opposite poles of the permanent magnet 2 and the electromagnet 1 are arranged in a staggered and opposite mode, if the battery is stolen by a person, the permanent magnet 2 and the electromagnet 1 in an electrified state attract each other when the battery is pulled out, the electromagnet 1 is lifted to the top end of the insulating track 3, the power supply 7 and the audible and visual alarm 6 form a passage through the lead 5, and therefore the audible and visual alarm 6 is electrified to emit light and noise, and the alarm effect is achieved.

Based on the principle, the alarm can be triggered only when the battery of the electric vehicle is in a state of locking the key and the battery is obviously displaced, and the alarm can not be triggered when the vehicle owner opens the lock of the battery by himself or the vehicle receives external force vibration of non-theft behavior, so that the anti-theft alarm is more accurate.
