Full-automatic truck fuel tank cap and control circuit

Abstract

The invention discloses a full-automatic truck fuel tank cap and a control circuit. The full-automatic truck fuel tank cap comprises a fuel tank body and an oil inlet, and stand columns are arranged on both sides of the oil inlet. The stand columns are fixedly connected with the oil tank body, and grooves are formed in the stand columns. The oil inlet is correspondingly provided with a fuel tank cap body, and the fuel tank cap body is movably connected with a sliding rod. The sliding rod is slidably connected with the stand columns, and the sliding rod is elastically connected with the tops ofthe grooves. Coils are arranged at the bottoms of the grooves, and iron blocks are arranged at the positions, corresponding to the coils, at the bottom of the sliding rod. In the control circuit, thepositive pole of a power supply DC is connected to a main control switch S and a fixed resistor R in sequence, the fixed resistor R is connected with an indicator light H and a rotary motor M separately, the rotary motor M is connected to a motor switch S1, and the indicator light H and the motor switch S1 are sequentially connected to a coil L, a passive switch S2 and the negative pole of the power supply DC. According to the full-automatic truck fuel tank cap and the control circuit, automatic opening of the fuel tank cap is controlled through the circuit, the cap opening time is saved, convenience is provided for drivers, and the indicator light in the circuit can timely detect whether the fuel tank cap is abnormal or not to prevent criminals from stealing oil during the parking break.

Description

technical field [0001] The invention relates to the technical field of fuel tank caps, in particular to a fully automatic truck fuel tank cap and a control circuit. Background technique [0002] Heavy-duty trucks are different from ordinary family cars. Many of its accessories take stability as the first consideration, which is different from the convenience and fashion of ordinary family cars. The fuel tank cap of heavy-duty trucks is also one of the very important accessories. Now In order to improve the safety performance of long-term driving, the fuel tank cap is mostly opened manually. When refueling, it needs to be opened manually. The operation is cumbersome, and the driver needs to get on and off the truck to open it, which causes a lot of inconvenience to the driver. During the driving process, the truck driver needs to stop to rest, and criminals steal oil when the truck driver stops to rest, and the driver cannot find out in time, causing economic losses to the dr...
