A portable generator set based on draw rod architecture

Abstract

A portable generator set based on a pull-rod framework. The generator set (1) is mainly composed of an engine (6), a generator (7) and a casing (5) and has a cuboid framework with length L, width W and height H. The engine (6) and the generator (7) are accommodated in the casing (5), and the engine (6) is connected with the casing (5) arranged at the bottom of the generator set. The left side face (103) or the right side face (104) formed by the length L and the width W in the cuboid framework of the generator set is provided with a pull type pull rod device (4), and the pull rod device (4) is vertically arranged along the height H direction of the generator set. By a series of adjustment and optimization designs, the generator set is more easy to move and can avoid bumping operators. Besides, space of the generator set can be utilized more reasonably, operation interface is improved, and portability and convenience in operation are greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of portable generator sets, in particular to a portable inverter generator set based on a pull rod structure. Background technique [0002] The generator set is mainly composed of an engine, a generator and an electronic control system. It can convert the chemical energy of fuel into electrical energy. Backup power supply, mobile communication base station and many other occasions. [0003] Compared with the traditional power frequency synchronous generator set, the inverter generator set using multi-pole permanent magnet generator has the advantages of high efficiency, small size and light weight. Its weight and volume are only about 50% of the traditional generator set, which is truly reliable Realize "portable" generator set. [0004] However, the weight of the inverter generator set of about 2kw is generally more than 20kg, so it is still very inconvenient to carry and carry. Such as Figure 1a , Fi...

Problems solved by technology

But this design has many problems, such as figure 2 As shown, when the operator lifts the front part of the generator set and drags the generator set 2 forward, since the generator set 2 is tilted backward (opposite to the forward direction), the P area 203 under the front part of the generator set is far away from the operator's feet It is very close to the legs, and it is easy to bump into the operator, which may cause injury in severe cases, which creates a great obstacle for the operator to quickly drag the generator set

Moreover, the action of the opening and retracting process of the rotary pull rod 202 is relatively complicated, the operation is not very convenient, and the efficiency is low.

On the other hand, in the process of dragging the generator set 2, the operator must always use an upward force F to overcome the weight G of the generator set to lift the front part of the generator set. Since the length L of the generator set 2 is relatively large (greater than the width W ), the distance B between the center of gravity of the generator set 2 and the center of the roller 201 in the horizontal direction is relatively large. , so F is relatively large, and it is still very laborious for the operator to carry the generator set 2

In addition, the two rollers 201 of the existing generator set 2 share one wheel shaft, and the wheel shaft running through the entire generator set 2 wastes the space inside the casing, so only rollers with smaller diameters can be used. Large, the adaptability to road conditions is poor, and the passing capacity of the generator set during transportation is also poor
