AI Technical Summary
Due to the small fuel tank capacity and no indication of oil quantity in the existing vehicle-mounted generator, it is difficult for users to judge the oil quantity and power supply time, and it is easy to cause the generator to lack oil and shut down and the frequency of refueling.
An improved vehicle-mounted generator oil supply system is designed. By opening an oil extraction hole in the chassis fuel tank and setting a plug cover and fuel pipe in the chassis hole, the fuel pipe takes oil from the chassis fuel tank and is connected to the generator fuel pump oil inlet.
By taking oil from the chassis fuel tank, users can observe the amount of oil through the main vehicle fuel indicator, extend the generator oil supply time, reduce the problems of oil shortage and frequent refueling, and improve the practicality of the system.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil supply for vehicle-mounted generators, in particular to an improved oil supply system for vehicle-mounted generators. Background Art
[0002] At present, the demand for special-purpose vehicles in my country has begun to show a growing trend, such as mobile dining cars, communication command vehicles, camping cars, inspection vehicles, etc. When these vehicles are parked, some special devices such as air conditioners, refrigerators, communication equipment, inspection instruments and other electrical equipment need to use electricity for a long time. If the engine on the chassis is used for power supply, the fuel consumption is high and it is not economical. At present, on this type of special vehicle, various manufacturers widely use on-board generators to power special equipment. The on-board generator has an independent fuel tank and fuel supply system, but because the fuel tank capacity is very small (relative to the chassis fuel tank) and there is no fuel level indicator, the user is not clear about the fuel tank oil level and the power supply time, which will cause the generator to shut down due to lack of oil and high refueling frequency. Utility Model Content
[0003] The purpose of the utility model is to provide an improved vehicle-mounted generator oil supply system, which is used to solve the technical problems existing in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] An improved vehicle-mounted generator fuel supply system comprises a chassis fuel tank, an oil extraction hole is opened at the upper part of the chassis fuel tank, a plugging cover is arranged inside the oil extraction hole, a fuel pipe is passed through the plugging cover, one end of the fuel pipe passes through the plugging cover and extends to a certain distance D above the bottom wall of the chassis fuel tank, and the other end is connected to the oil inlet of the generator fuel pump.
[0006] Furthermore, the plugging cover is interference-fitted with the oil extraction hole and the fuel pipe respectively.
[0007] Furthermore, a through hole for passing a fuel pipe is provided in the middle of the plugging cover.
[0008] Furthermore, a slot for engaging with the oil extraction hole is provided on the outer peripheral wall of the plugging cover.
[0009] Furthermore, the distance D is 10 mm.
[0010] Compared with the prior art, the advantages of the utility model are as follows: by improving the existing independent fuel supply method of the vehicle-mounted generator to taking oil from the chassis fuel tank, the user can observe the oil level in the tank from the fuel indicator of the main vehicle; at the same time, since the chassis fuel tank has a large capacity, the time for supplying oil to the generator is extremely long, so it is not easy to cause problems such as oil shortage and frequent refueling, and it has strong practicality.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.
[0018] See also Figures 1 to 3 The utility model provides an improved vehicle-mounted generator fuel supply system, comprising a chassis fuel tank 1, an oil extraction hole 2 is opened on the upper part of the chassis fuel tank 1, a plugging cover 3 is arranged inside the oil extraction hole 2, a fuel pipe 4 is passed through the plugging cover 3, one end of the fuel pipe 4 passes through the plugging cover 3 and extends to a certain distance D above the bottom wall of the chassis fuel tank 1, and the other end is connected to the fuel inlet 5 of the generator fuel pump.
[0019] Furthermore, in order to ensure that there is no oil leakage at the joint surface between the fuel pipe 4 and the chassis fuel tank 1, the plugging cover 3 and the oil extraction hole 2 and the fuel pipe 4 are all interference fit.
[0020] Specifically, as a preferred example of the plugging cover 3: Figure 4 A through hole 6 for passing the fuel pipe 4 is opened in the middle of the plugging cover 3 according to the diameter of the fuel pipe 6.
[0021] Specifically, in the preferred embodiment of the plug cover 3, in order to increase the reliability of the connection between the plug cover 3 and the chassis fuel tank 1, refer to Figure 4A slot 7 for engaging with the oil extraction hole 2 is provided on the outer peripheral wall of the plug cover 3. The provision of the slot 7 can, on the one hand, make the plug cover 3 firmly connected to the chassis fuel tank 1, and on the other hand, can well prevent the fuel in the chassis fuel tank 1 from leaking through the joint surface between the plug cover 3 and the chassis fuel tank 1.
[0022] Specifically, in the present invention, the distance D between the fuel pipe 4 and the inner bottom wall of the chassis fuel tank 1 is 10 mm. This design can ensure that the generator 8 is supplied with oil for a long time, so that the generator 8 is not prone to the problem of oil shortage and shutdown.
