Description

Technical Field

[0001] This utility model relates to the field of variable frequency generators, and in particular to a novel open-frame variable frequency generator. Background Technology

[0002] Traditional open-frame variable frequency generators, such as Figure 1 The present design suffers from two drawbacks: Firstly, inverters are typically installed either front-mounted (in front of the engine starter) or top-mounted (on top of the engine). The former requires an additional protective cover, resulting in an excessively large overall size, while the latter raises the center of gravity, affecting stability. Secondly, traditional low-power inverters (weighing less than 15kg) are usually designed with a square, double-bar frame, requiring the user to carry it with both hands. If one hand is used to grip one of the bars, the machine will tilt, causing fuel to leak, which is very unsafe. However, carrying it with both hands negates its small and portable advantage.

[0003] Therefore, those skilled in the art are dedicated to developing a new type of open-frame variable frequency generator that can simultaneously solve the problems of compact heat dissipation and safe handling. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to provide a novel open-frame variable frequency generator.

[0005] To achieve the above objectives, this utility model provides a novel open-frame inverter generator, including a first bracket with an engine, a second bracket on the first bracket, a panel fixedly connected to the second bracket, and an inverter on the side of the panel near the engine.

[0006] Preferably, the engine is provided with a wind deflector, and the wind deflector has an air vent facing the inverter.

[0007] Preferably, the first bracket includes a first connecting rod, and the two ends of the first connecting rod are respectively provided with a radially extending second connecting rod and a third connecting rod.

[0008] Preferably, the second bracket includes a fourth connecting rod, and the two ends of the fourth connecting rod are respectively provided with a fifth connecting rod and a sixth connecting rod, and the fifth connecting rod and the sixth connecting rod are respectively connected to the second connecting rod and the third connecting rod.

[0009] Preferably, the engine is provided with a grip bar on top, and one end of the grip bar is connected to the fourth connecting rod.

[0010] Preferably, the end of the grip bar away from the fourth connecting rod is provided with a vertical rod, one end of which is connected to the grip bar, and the other end of which is connected to the first connecting rod.

[0011] Preferably, the first connecting rod is connected to the second and third connecting rods, the fourth connecting rod is connected to the fifth and sixth connecting rods, and the grip rod is connected to the vertical rod using an arc-shaped tube transition connection.

[0012] Preferably, at least one crossbar is provided between the second connecting rod and the third connecting rod, and the crossbar is threadedly connected to the engine.

[0013] The beneficial effects of this utility model are: by placing the inverter on its side and integrating it with the panel, this utility model effectively reduces the overall size of the machine, lowers the center of gravity, and improves its operational stability. Furthermore, this application also provides a novel support structure that is easier for users to move while offering higher safety and significantly reducing manufacturing costs, thus possessing considerable market potential.

[0021] like Figure 2-5 As shown, a novel open-frame inverter generator includes a first bracket 1 housing an engine 3. In this embodiment, the first bracket 1 is horizontally positioned at the bottom of the device as a mounting base, and includes a first connecting rod 11 and a second connecting rod 12 and a third connecting rod 13 extending radially along the first connecting rod 11. Further, the first bracket 1 also has a vertically extending second bracket 2, which includes a fourth connecting rod 21 and a fifth connecting rod 22 and a sixth connecting rod 23 extending radially along the fourth connecting rod 21. Furthermore, the fifth connecting rod 22 and the sixth connecting rod 23 are respectively connected to the second connecting rod 12 and the third connecting rod 13. This design allows the first bracket 1 and the second bracket 2 to together form an upwardly bent rectangular structure, providing support for the engine 3 and other components. In this embodiment, the first bracket 1 and the second bracket 2 are manufactured using an integral molding technique to ensure their structural strength.

[0022] In this embodiment, a horizontally extending grip bar 6 is also provided on the top of the engine 3. One end of the grip bar 6 is connected to the middle of the fourth connecting rod 21. With the centrally positioned grip bar 6, the user can grasp it with only one hand when carrying it, greatly improving the user experience. Furthermore, a vertical rod 7 is provided at the end of the grip bar 6 away from the fourth connecting rod 21. One end of the vertical rod 7 is connected to the grip bar 6, and the other end is connected to the first connecting rod 11. The vertical rod 7 supports the grip bar 6 and, together with the first bracket 1 and the second bracket 2, forms a complete support structure. In specific implementation, the first connecting rod 11, the second connecting rod 12, the third connecting rod 13, the fourth connecting rod 21, the fifth connecting rod 22, the sixth connecting rod 23, the vertical rod 7, and the grip bar 6 are all manufactured by integral molding of hollow steel tubes. This design can achieve a 20-30% weight reduction while maintaining the same bending stiffness. Meanwhile, the first connecting rod 11 is connected to the second connecting rod 12 and the third connecting rod 13, the fourth connecting rod 21 is connected to the fifth connecting rod 22 and the sixth connecting rod 23, and the handle 6 and the vertical rod 7 are all connected by arc-shaped tubes. By setting arc-shaped tubes at each corner, the structural stress is dispersed, the service life of the structure is improved, and the production and manufacturing costs are reduced.

[0023] At least one crossbar 14 is provided between the second connecting rod 12 and the third connecting rod 13, and the crossbar 14 is threadedly connected to the engine 3. In this embodiment, there are two crossbars 14, which are arranged in parallel and spaced apart, and the engine 3 is screwed onto the two crossbars 14.

[0024] like Figure 2 As shown, a panel 4 is fixedly attached to the second bracket 2. Panel 4 integrates various function buttons for unified management. The two sides of panel 4 are screwed to the fifth connecting rod 22 and the sixth connecting rod 23, respectively, which provide a mounting base for panel 4. Furthermore, an inverter 5 is also located on the side of panel 4 closest to the engine 3. Positioning the inverter 5 inside panel 4 allows panel 4 to function as a protective cover. Compared to existing technologies, this application eliminates the design of an outer cover for the inverter 5, reducing the overall size of the device. Simultaneously, the close proximity of panel 4 to inverter 5 significantly reduces the wiring harness routing and manufacturing process complexity between the two.

[0025] like Figure 3 As shown, the engine 3 is equipped with a wind deflector 31, and the wind deflector 31 has an air vent 31a facing the inverter 5. By opening the air vent 31a on the wind deflector 31 facing the inverter 5, the inverter 5 is cooled by the cooling air discharged from the engine 3. Compared with the traditional cooling scheme where the inverter 5 is installed in front of the starter of the engine 3 and uses natural air cooling or intake air cooling, this application has a smaller size and higher cooling efficiency. Compared with the traditional scheme where the inverter 5 is placed on top of the engine 3 with an exhaust vent for cooling, this application can reduce the height of the generator, lower the center of gravity of the whole machine, improve stability, and reduce costs.

[0026] When in use, the machine position is adjusted by gripping the lever 6 with one hand. After the machine is adjusted to the appropriate position, the engine 3 is started. The cold air in the engine 3 is gathered in the air guide shroud 31, and part of the cold air is output to the inverter 5 for cooling through the air guide vent 31a.

[0027] This application effectively reduces the overall size of the unit, lowers the center of gravity, and improves operational stability by placing the inverter 5 on the side and integrating it with the panel 4. Furthermore, this application provides a novel support structure that is easier for users to move while offering higher safety and significantly reducing manufacturing costs, making it highly valuable for market promotion.

[0028] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
