The utility model provides a theftproof pressure switch of storage battery car battery box, including power GB, pressure switch element, load element, ground element, power GB, pressure switch element, load element establish ties, load element is bee calling organ BL, power GB connects ground element, ground element is storage battery protection shield GND.

Further, the pressure switch element comprises a pressure sensor BP, a normally open contact NO, a knife switch S, a normally closed contact NC and a multi-contact relay K, the knife switch is connected with the negative electrode of the pressure sensor BP, the knife switch S can be switched between the normally open contact NO and the normally closed contact NC, the normally open contact NO and the normally closed contact NC are both arranged on the multi-contact relay K and are connected with the negative electrode of the multi-contact relay K, the positive electrode of the multi-contact relay K is connected with the negative electrode of a power supply, the negative electrode of the multi-contact relay K is connected with the negative electrode of a buzzer BL, and the multi-contact relay K and the buzzer BL are connected on the main circuit in parallel.

Compared with the prior art, the beneficial effects of the utility model reside in that:

firstly, when the storage battery is stolen, the storage battery box is taken up to trigger a pressure switch device under the storage battery box, the buzzer is communicated to give an alarm, the buzzer makes a sound, a vehicle owner can be reminded, and the anti-theft effect is achieved.

Secondly, the whole device has simple structure and small size, can be arranged under the storage battery box only by occupying little space, and is very convenient and practical.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention.

The components of the embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

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 in specific cases to those skilled in the art.

The following description is made with reference to fig. 1, an embodiment of the present invention provides an anti-theft pressure switch for a battery box of a battery car, which includes a power supply GB, a pressure switch element, a load element, and a ground element, where the power supply GB is a fixed voltage power supply for a battery in the battery car, the load element is a buzzer BL, the ground element is a battery protection board GND, the pressure switch closing element includes a pressure sensor BP, a normally open contact NO, a knife switch S, a normally closed contact NC, and a multi-contact relay K, a negative electrode of the power supply GB is connected with a positive electrode of the buzzer BL and a positive electrode of the multi-contact relay K, a negative electrode of the buzzer BL is connected with a negative electrode of the relay K and a positive electrode of the pressure sensor BP, the pressure sensor BP is not powered or is not enough to support the operation of the buzzer BL, but the negative electrode of the pressure sensor BP is connected with the knife switch and can control the knife switch S to form the, the power GB and the buzzer BL are connected in series through the pressure switch, the multi-contact relay K is connected with the buzzer BL in parallel, and the storage battery protection board GND is connected with the positive electrode and the negative electrode of the power GB to protect the whole circuit and prevent short circuit.

When the storage battery of the storage battery car is in the storage battery box, the pressure sensor BP can transmit a power-off signal to the switch blade S, the switch blade S is located on the normally-open contact NO under the condition that the power supply discharges, the whole circuit is in a circuit-breaking state, and the buzzer BL does not work.

When the storage battery of the storage battery car is separated from the storage battery box, the pressure sensor BP can transmit a power-on signal to the switch blade S, the switch blade S is positioned on the normally closed contact NC under the condition that the power supply discharges, the whole circuit is in a channel state, and the buzzer BL starts working and sends out a loud alarming whistle.
