Portable inversion gasoline generator set

Abstract

A portable inversion gasoline generator set is disclosed, comprising a shell and an engine assembly arranged in the shell. The engine assembly comprises an engine, a generator, a carburetor arranged on a cylinder head of the engine and an air filter connected with the carburetor. The portable inversion gasoline generator set is characterized in that the shell includes a rectangular enclosure framewhich is defined by a front cover shell, a rear cover shell, a left side plate and a right side plate and fixed through connecting pieces, and an oil tank fixed to the top of the rectangular enclosure frame; a plurality of upper supporting pipes and a plurality of lower supporting pipes are fixed between the left side plate and the right side plate; the upper portion and the lower portion of theengine assembly are fixed to pipe connecting pieces and are fixed to the upper supporting pipes and the lower supporting pipes respectively through the pipe connecting pieces; the air filter is fixedly or integrally arranged on one of the left side plate and the right side plate close to the carburetor; and an air outlet of the air filter is connected with an air inlet of the carburetor through anelastic hose. An existing inner supporting frame is omitted, the accumulated tolerance between components is reduced, the whole body is easier to assemble, and better anti-seismic property and working stability are achieved.

Description

technical field [0001] The invention relates to a portable inverter gasoline generator set. Background technique [0002] The company originally designed a portable inner frame type inverter gasoline generator set for the purpose of simplifying assembly and facilitating maintenance. The engine assembly, the front and rear covers, the left and right side panels, the top fuel tank and the air filter, and the control panel for the inverter assembly is placed on the front cover. This design makes the assembly of the whole generating set more convenient and quick, shortens the production time, saves the production cost and improves the production efficiency. And ensure that each part of the generator set is configured independently, simplify the internal structure, and facilitate disassembly and maintenance. [0003] However, in the process of continuous use, we found that the above-mentioned portable inner frame inverter gasoline generator set exposed the following problems: ...

AI Technical Summary

Problems solved by technology

However, due to the introduction of the inner support frame, the cumulative tolerance between the engine assembly and the side plate increases, resulting in a large deviation between the air filter and the opening that matches the air filter on the side plate, and there is no guarantee that the two can be installed coincide

[0006] 2) The introduction of the inner support frame, the problem caused by a large number of components at the same time is that when the generator set is working, the overall vibration is relatively large, although the vibration can be reduced by introducing a shock absorber structure between the inner support frame and the engine assembly

However, as mentioned in 1) above, the introduction of the shock-absorbing structure leads to further accumulation of tolerances between components, which is even more unfavorable for assembly

[0007] 3) The vibration of the generator set is too large, causing oil to leak from the air hole of the top fuel tank, and at the same time, it will cause damage to the electrical components in the front cover, such as the inverter, which hinders its normal and effective work, and the carburetor Even more detrimental effect on the stability of the connection between the air filter and the
