In the drawings:

fig. 1 is a diagram of a battery anti-theft circuit system according to an embodiment of the present invention.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, a battery anti-theft circuit system includes a trigger unit U2 and a sensing element;

the sensing assembly comprises a sensing unit U1 for sensing the trigger unit U2, and an alarm U3 directly or indirectly connected with the sensing unit U1; the sensing unit U1 is directly connected with the alarm U3 through a circuit, in addition, the sensing unit U1 can be connected with the alarm U3 through a controller, the scheme adopts the prior art to realize the alarm U3 to give an alarm, and therefore further description is omitted in the patent application;

The sensing unit U1 is a Hall switch, the power supply end VDD of the Hall switch is connected with the positive power supply end of the alarm U3, the output end OUT of the Hall switch U1 is connected with the signal detection end of the alarm U3, the grounding end GND of the Hall switch U1 is connected with the negative power supply end of the alarm U3, and the negative power supply end of the alarm U3 is grounded.

The triggering unit U2 is a magnet, and the magnet is used for triggering the Hall switch; the magnet is fixedly arranged on the battery compartment cover, the Hall switch is fixedly arranged on the battery compartment base, when the battery compartment cover is covered, the Hall switch is closed, when the battery compartment cover is opened, the Hall switch is disconnected, the alarm can know whether the battery compartment cover is installed in place or not through detecting the opening and closing state of the Hall switch, and the battery anti-theft effect is achieved by continuously alarming when the battery compartment cover is not in place.

The positive end of the power supply of the alarm U3 is electrically connected with the signal detection end of the alarm U3 through a pull-up resistor R1.

When the scheme is implemented, the Hall switch U1 is arranged on the base of the battery compartment and is connected with the alarm U3 according to the circuit shown in fig. 1, the magnet U2 matched with the Hall switch for use is arranged at the corresponding position of the battery compartment cover, and the magnetic pole of the magnet U2 is ensured to be vertical to and close to the front side of the Hall switch U1 after the compartment cover is arranged in place;

in practical application, when the battery hatch cover is installed in place, the Hall switch U1 is switched on, the signal detection end of the alarm U3 receives a low-level signal, and the alarm U3 does not act; when the battery compartment cover is moved or opened, the Hall switch U1 is disconnected, and the signal detection end of the alarm U3 receives a high level signal and sends out a high decibel alarm sound to continuously alarm.
