Description

Technical Field

[0001] This utility model relates to the field of generator technology, and in particular to a variable frequency generator oil tank structure with an oil guide groove. Background Technology

[0002] The fuel tank is a component on a variable frequency generator used to store gasoline. The basic structure of the fuel tank includes the tank itself with a filler neck and a cap that covers the filler neck. When refueling, the cap is removed, and fuel is added to the tank through the filler neck. During this process, some fuel may overflow from the filler neck to the outside of the tank. In some generator layouts, a circuit board is compactly placed next to the fuel tank; overflowing fuel can then flow onto and damage the circuit board. Utility Model Content

[0003] The present invention aims to provide a variable frequency generator oil tank structure with an oil guide groove that allows overflowing oil to flow in a set direction, thereby solving the problem that random flow of oil when it flows out of the existing oil tank will damage the adjacent circuit board.

[0004] The following technical problem is solved by the following technical solution: A variable frequency generator oil tank structure with an oil guide groove, comprising an oil tank with an oil filling port and an oil tank cover covering the oil tank opening, characterized in that the oil filling port protrudes from the oil tank, an oil receiving plate is fitted onto the oil tank opening, the upper surface of the oil receiving plate has an oil receiving pit to catch oil leaking from the oil filling port, and the oil receiving pit has an oil drain outlet; in use, a circuit board is located next to the oil tank, and the oil drain outlet is located on the side of the oil receiving pit away from the circuit board. When oil overflows from the oil tank, it falls onto the oil receiving plate and collects in the oil receiving pit, and then drains to a designated location through the oil drain outlet, preventing the oil from randomly flowing around and damaging surrounding circuit boards and other components.

[0005] Preferably, the upper surface of the oil tank is provided with an oil drain groove, and the oil drain port is located above the oil drain groove. This allows overflowing oil to be drained to a designated location.

[0006] Preferably, the oil drain groove extends perpendicular to the distribution direction of the circuit board and the oil tank. This effectively increases the strength of the oil tank.

[0007] Preferably, the oil receiving plate has several protruding strips on the side away from the circuit board. The upper surface of each protruding strip has an oil drain groove, one end of which communicates with the oil receiving recess, and the other end passes through the end face of the protruding strip to form the oil drain port. This allows oil to be drained further away from the circuit board, improving the reliability of the circuit board and preventing oil damage. It also keeps the material consumption of the oil-saving plate low.

[0008] Preferably, the oil receiving recess has a protrusion in the middle, making the oil receiving recess annular and extending circumferentially along the filler neck, with the filler neck passing through the protrusion. This reduces unintended oil leakage from the connection between the oil receiving plate and the filler neck.

[0009] Preferably, the protrusion is sealed together with the filler neck. This more reliably prevents unintended oil leakage from the connection between the filler plate and the filler neck.

[0010] Preferably, the oil receiving plate is made of rubber, and the protrusion relies on its own elasticity to elastically seal with the oil filling port. This provides good convenience in achieving a seal, requires fewer parts, and eliminates the need for a sealing ring.

[0011] Preferably, the outer edge of the oil receiving plate is provided with a skirt, and the skirt forms a groove with the peripheral surface of the oil receiving plate. This increases the planar area of ​​the oil receiving plate, providing better oil blocking and absorption, and improving structural strength.

[0012] Preferably, the groove is provided with several reinforcing ribs connecting the skirt and the oil receiving plate together. This further improves the structural strength. This invention has the following advantages: it can collect oil flowing from the filler neck, and the collected oil can be discharged in a set direction, thereby avoiding damage to electrical components such as circuit boards next to the fuel tank.
