Description

Anti-theft fuel tank cover

Technical Field

The utility model relates to a theftproof fuel tank lid.

Background

Motor vehicles are continuously increased in life, meanwhile, the oil price is continuously increased, fuel oil cases in automobile fuel tanks are stolen occasionally, the cases become a great worry of drivers and automobile owners at present, vehicle operators who often go out are greatly troubled, and the automobile fuel oil is stolen, so that economic loss is brought to the vehicle operators, and serious potential safety hazards can be caused.

The invention discloses an electronic anti-theft oil tank cover, which comprises an oil tank cover and an anti-theft unlocking key, wherein the existing electronic anti-theft oil tank is complex in structure, the Chinese patent application number is 201810919088.5, and a first through hole is formed in one surface of the oil tank cover; the lock core is in clearance fit with the inner wall of the first through hole; lock grooves are arranged on the peripheral side surface of the lock core along the axial direction in a linear way; one end of the lock cylinder is provided with a lock hole; the peripheral side surface of the oil tank cover is provided with first circular grooves in linear arrangement along the axial direction; a rectangular groove is formed in the oil tank cover; a first rectangular hole is linearly arranged on the inner wall of the rectangular groove along the axial direction; the first rectangular hole is communicated with the first circular groove; the other inner wall of the rectangular groove is provided with second rectangular holes in linear arrangement along the axial direction. According to the invention, through the designed oil tank cover, the lock core, the lock shell, the first lock block, the second lock block and the anti-theft lock key, when the lock is unlocked, the anti-theft lock key pushes two correct first lock blocks to release the electronic lock, and the second lock block is pushed to trigger the alarm. The invention has the anti-theft effect, but brings trouble to users and has a complicated process of opening the fuel tank cover.

Disclosure of Invention

The utility model aims at the not enough of prior art, provide an theftproof fuel tank lid, prevent burglary through the electron trick lock, and can record thief's action and characteristic.

In order to achieve the above object, the utility model discloses a following scheme realizes: the anti-theft fuel tank cover comprises a base and a tank cover, wherein the tank cover is connected with the base through a connecting part, a coded lock is arranged on the tank cover, an oil filling hole is formed in the top of the base, and a coded lock base matched with the coded lock is arranged on the base.

The base is equipped with microcontroller, alarm, the trick lock base is equipped with micro-gap switch, microcontroller is connected with alarm and micro-gap switch electricity respectively.

The microcontroller is electrically connected with the coded lock. The base is provided with a camera, and the camera is electrically connected with the microcontroller.

The alarm is a flash lamp and/or a buzzer.

The utility model has the advantages that: 1. through the combination of the coded lock, the microswitch and the alarm, when the correct code is not input or the coded lock is damaged manually, the oil tank cover can give an alarm to prevent someone from stealing oil;

2. through the setting of camera, can carry out the record to thief's action and characteristic.

Drawings

The invention will be further explained with reference to the drawings:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a circuit diagram of an electromagnetic relay control module;

FIG. 3 is a circuit diagram of an audible alarm;

in the figure: camera 1, trick lock base 2, tank filler hole 3, connecting portion 4, trick lock 5, case lid 6, alarm 7, base 8.

Detailed Description

As shown in figure 1, the anti-theft fuel tank cover comprises a base 8 and a tank cover 6, wherein the tank cover 6 is connected with the base 8 through a connecting part 4, a coded lock 5 is arranged on the tank cover 6, an oil filling hole 3 is formed in the top of the base 8, and a coded lock base 2 matched with the coded lock 5 is arranged on the base 8.

The base 8 is provided with a microcontroller and an alarm 7, the coded lock base 2 is provided with a microswitch, and the microcontroller is respectively electrically connected with the alarm 7 and the microswitch. When external force acts on the coded lock base 2, the driver component of the microswitch transmits the force to the action reed and generates corresponding displacement, and when the reed moves to a certain critical point, the switch is triggered to act, so that the movable contact at the tail end of the action reed is quickly connected with the fixed contact.

The microcontroller is electrically connected with the coded lock 5. When the password input by the user is correct, the singlechip outputs a driving signal to the electromagnetic relay to control the coded lock to be unlocked. The circuit diagram of the electromagnetic relay control module is shown in fig. 2, the relay chamber is driven by a PNP type triode, when the threshold value exceeds the set value, the single chip jumps from high level to low level, the triode is conducted to the relay for attraction, and the relay plays a role of switching and can drive the load.

The base 8 is provided with a camera 1, and the camera 1 is electrically connected with the microcontroller.

The alarm 7 is a flash lamp and/or a buzzer. With the structure, the alarm can be given in the forms of flashing light and sound. Buzzer sound alarm circuit as shown in fig. 3, the triode Q1 acts as a switch, the low level of its base electrode makes the triode saturated and conducted, making the buzzer sound; and the triode is closed by the high base level, and the buzzer stops sounding.

Example (b):

an AT24C02 chip of Atmel can be used as a memory for storing data such as preset coded lock passwords and the like. The microcontroller adopts an STC89C51 singlechip, and the micro-switch adopts a ZW3-1I series micro-switch of the Mount Zhejiang Mitsu electric company Limited.

The singlechip compares the input password with the password preset in the memory, and if the input password is correct, the singlechip sends a driving signal to the electromagnetic relay to unlock. And after the lock is unlocked, the oil is added through the oil adding hole 3. If the input password is incorrect, the single chip microcomputer sends an alarm signal alarm 7 to give an alarm, so that the alarm can remind a user and warn a thief. When external force acts on the coded lock base 2, the single chip microcomputer receives a contact signal of the microswitch and does not receive a code input signal, an alarm signal is sent to the alarm 7, the alarm 7 gives an alarm, and meanwhile the microcontroller sends a control signal to the camera 1. When man and machine destroys the trick lock, report to the police and the camera is to user's action and characteristic record.
