[0002] Reverse starting is a common generator starting method. Its purpose is to reverse the generator's rotational direction to accelerate the generator in advance, achieving a quick start. However, reverse starting requires a specialized controller. Similarly, the inverter is a core electrical component in a variable frequency generator set. To facilitate connection between the inverter and the operating panel, it is usually installed behind the panel base.

[0003] Generator sets also include electrical components like batteries and carbon monoxide alarms, all of which must be installed within the generator housing. If these components are installed far apart, the amount of wiring harnesses required will increase installation costs. Furthermore, the scattered installation locations of these components complicate the assembly process. Utility Model Content

[0029] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0032] like Figure 1-6As shown, in one embodiment of the present invention, a panel seat assembly and a variable frequency generator set are provided. The panel seat assembly includes a panel body 10, and an anti-drag controller 20, an inverter 30, a battery 40, and an alarm 50 arranged on the rear side of the panel body 10. The front side of the panel body 10 is recessed rearward to form a mounting groove 11, and the operation panel is installed in the mounting groove 11. The mounting groove 11 is formed with a raised portion 12 on the rear side of the panel body. The anti-drag controller 20 is arranged on the side of the raised portion 12 facing away from the mounting groove 11, and the inverter 30 is arranged below the raised portion 12. Among them, the variable frequency generator set includes the above-mentioned panel seat assembly.

[0033] The present embodiment discloses a panel seat assembly and a variable frequency generator set, which integrates the reverse drag controller 20, the inverter 30, the battery 40 and the alarm 50 on the panel body 10. Since the spacing between these electrical components is close, the length of the wiring harness used to connect the electrical components to the operation panel will be greatly shortened, thereby reducing the amount of wiring harness used and improving the economy of the whole machine assembly process. At the same time, since these electrical components are all installed on the panel plate body, this simplifies the assembly process of the whole machine and improves production efficiency. In addition, since the inverter 30 is relatively large in size, by installing it below the raised portion 12, the space on the rear side of the panel body 10 is fully utilized, making the layout of the entire panel seat assembly more regular and reducing the space occupied by the panel seat assembly.

[0034] In one embodiment, the raised portion 12 is provided with four through-holes 13 extending through the bottom of the mounting groove 11. The anti-drag controller 20 is provided with four mounting holes 21, the number of which corresponds to the number of through-holes 13. A positioning portion is provided on the side of the raised portion 12 facing away from the mounting groove 11. When the anti-drag controller 20 is positioned within the positioning portion, each through-hole 13 aligns with a mounting hole 21.

[0035] The anti-drag controller 20 is fastened to the raised portion 12 by bolts. Specifically, the bolts pass through the through holes 13 and are threadedly connected to the corresponding mounting holes 21. After tightening the four bolts, the anti-drag controller 20 can be fixed to the raised portion 12. At the same time, because the bolts engage the mounting holes 21 from the side of the mounting groove 11, there is no need to use nuts to fix the anti-drag controller 20, which saves the number of fixing parts.

[0036] Furthermore, the positioning portion includes four stoppers 14, each of which is a bent structure and is disposed around the four corners of the anti-drag controller 20. During assembly, after aligning the four corners of the anti-drag controller 20 with the four stoppers 14, each through hole 13 will align with the corresponding mounting hole 21, thereby improving assembly convenience.

[0037] In one embodiment, an air duct 61, an air inlet gap 62 and an air outlet gap 63 are formed between the inverter 30 and the panel body 10. The air inlet gap 62 and the air outlet gap 63 are respectively connected to the air duct 61. The air inlet gap 62 is close to the bottom of the panel body 10, and the air outlet gap 63 is close to the raised portion 12. The heat dissipation part of the inverter 30 is located in the air duct 61.

[0038] The panel body 10, together with the frame, bottom plate, side plates, and rear plate (not shown in the drawings), forms the generator set's housing. When the power source is running, a negative pressure forms inside the housing, causing outside air to be drawn into the housing through the air inlet gap 62, air duct 61, and air outlet gap 63, thereby cooling the power source and other components. As air flows through the air duct 61, it passes through the channels between the heat sinks of the inverter 30, removing heat from these heat sinks and cooling the inverter 30. This eliminates the need for an additional cooling device to cool the inverter 30, saving costs.

[0039] In one embodiment, an auxiliary air inlet hole 15 is provided on the panel body 10 between the air inlet gap 62 and the air outlet gap 63. The auxiliary air inlet hole 15 is connected to the air duct 61, and the outside air can also enter the air duct 61 through the auxiliary air inlet hole 15, thereby further improving the air intake effect.

[0040] In one embodiment, the panel body 10 is provided with two spaced-apart support blocks 16 extending along the height of the panel body 10. The inverter 30 is fixed to the two support blocks 16 by bolts. The inverter 30, the panel body 10, and the two support blocks 16 together form an air duct 61. The design of the two support blocks 16 not only secures the inverter 30 but also blocks airflow, allowing most of the airflow in the air duct 61 to flow out only through the air outlet gap 63. This improves the cooling effect on the inverter 30 and ensures its normal operation.

[0041] In one embodiment, a mounting bracket 70 is provided on the raised portion 12, and the battery 40 is fixed to the mounting bracket 70 via a bolt. To secure the battery 40, a support block 71 is formed on the mounting bracket 70, which is bent. The battery 40 is placed on the support block 71, which has a socket 711. The bottom of the battery 40 is provided with a tongue 41, which plugs into the socket 711.

[0042] In one embodiment, the alarm 50 is located below the battery 40 and on one side of the inverter 30. The panel body 10 is provided with an air inlet 17, and the alarm 50 is close to the air inlet 17. The alarm 50 is used to monitor CO gas. When the CO concentration exceeds the alarm limit of the alarm 50, the alarm 50 will shut down the internal combustion engine.

[0043] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
