[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] This embodiment provides an inverter, including a housing 100 and a control panel 1 disposed on the housing 100. Further, referring to Figures 1 to 6, the control panel 1 includes a circuit board 11, a display screen 15, and a mounting plate 12. The mounting plate 12 is fixed to the housing 100, and a sealing body is disposed between the mounting plate 12 and the housing 100. The sealing body includes a sealant layer 122 coated on the housing 100, and the sealant layer 122 fills the gap between the mounting plate 12 and the housing 100, resulting in good sealing performance of the inverter.

[0031] Furthermore, the mounting plate 12 has a transparent display area 124 and multiple hooks 16 arranged around the display area 124. The display screen 15 is located inside the display area 124 and is constrained between the multiple hooks 16. The circuit board 11 is fixed on the mounting plate 12 and the display screen 15 is located between the circuit board 11 and the mounting plate 12. The display screen 15 can display the inverter's operating status and output voltage in real time, playing the role of monitoring, protecting and regulating the inverter. The housing 100 is provided with a display window corresponding to the display screen 15. Furthermore, the display area 124 protrudes from the plane where the mounting plate 12 is located. The display area 124 is provided with a display screen groove, and the display screen 15 is located in the display screen groove. The depth of the display screen groove is less than the thickness of the mounting plate 12.

[0032] As shown in Figures 4 and 5, the first inner side of the mounting plate 12 is provided with two first hooks, and the second inner side is provided with two second hooks. The display screen 15 is clamped between the first hooks and the second hooks. During assembly, the display screen 15 is pressed down directly, the hooks are deformed by force, and the display screen 15 falls directly into the slot of the hooks. The installation is relatively convenient and saves time.

[0033] Referring to Figures 2 and 3, a touch portion 13 is provided on the circuit board 11. The touch portion 13 includes a button body and a trigger. The button body is located on the circuit board 11 and is electrically connected to the circuit layer on the circuit board 11. The trigger is specifically a spring. The mounting plate 12 includes a touch portion 17 and a limiting sleeve 121 extending from the touch portion 17 into the housing 100. The spring is disposed in the limiting sleeve 121. One end of the spring can abut against the touch portion 13, and the other end of the spring can abut against the button body. The spring is configured to deform when the touch portion 13 is touched to trigger the button body to generate an electrical signal. The housing 100 is provided with a touch window that exposes the touch portion 13. The touch portion is relatively thin. When the operator touches the touch portion 13, the touch portion 13 will undergo a slight deformation, the spring will be compressed, the button body will be triggered, and an electrical signal will be generated.

[0034] Specifically, the limiting sleeve 121 has a receiving groove 1211 for accommodating a spring, with the spring located within the receiving groove 1211. Specifically, there are multiple limiting sleeves 121, specifically four, with each limiting sleeve 121's receiving groove 1211 accommodating one spring. More specifically, the receiving groove 1211 has an open end and a closed end. The spring has a welding end 131 and an abutting end 132. The welding end 131 is welded and fixed to the circuit board 11 and abuts against the button body. The closed end forms the bottom wall of the receiving groove, and the abutting end 132 abuts against the bottom wall of the receiving groove 1211, or in other words, the abutting end 132 abuts against the touch portion 13. When the circuit board 11 and the mounting plate 12 are fastened together, as the screws are tightened, the abutting end 132 of the spring and the bottom wall of the receiving groove 1211 come into tight contact, achieving good electrical contact.

[0035] Referring to Figures 2 and 3, the elastic element has a first elastic segment 133 and a second elastic segment 134, with the second elastic segment 134 abutting against the bottom wall of the receiving groove 1211. The first elastic segment 133 is a vertical spiral, and the second elastic segment 134 is coiled, resembling a "Swiss roll". In terms of direction, the first elastic segment 133 is arranged vertically, and the second elastic segment 134 is arranged horizontally. The tail end of the first elastic segment 133 connects to the head end of the second elastic segment 134, and the second elastic segment 134 is in close contact with the bottom wall of the receiving groove 1211. Here, "tail end" refers to the lowest point of the first elastic segment 133 in Figure 3, and "head end" refers to the innermost side of the second elastic segment 134 in Figure 3.

[0036] The touch portion 17 is the closed end of the limiting sleeve 121, which protrudes from the plane of the mounting plate 12 and forms the touch portion of the photovoltaic inverter. During operation, only the touch portion 17 needs to be touched. Since the touch portion 17 is essentially part of the limiting sleeve 121, and the limiting sleeve 121 is not a through hole, even if liquid enters the gap between the touch portion 17 and the housing 100, the sealant layer 122 prevents the liquid from entering the interior of the photovoltaic inverter, providing excellent waterproof sealing. Furthermore, unlike physical buttons, there is no need to design a special silicone sleeve for the button, saving on usage costs.

[0037] Furthermore, there are four limiting sleeves 121 and four receiving slots 1211, corresponding to four touch units 17. Each touch unit 17 includes a mode selection button, a start / stop button, a power adjustment button, and a display screen operation button. The mode selection button is typically used to switch the inverter's operating mode. Different inverters may have different operating modes, such as AC mode, battery mode, and hybrid mode. By pressing the mode selection button, the user can select the appropriate operating mode according to their needs. The start / stop button is used to control the inverter's on / off state. When the user needs to turn on the inverter, they simply press the start button. The inverter will then start working. Conversely, when the user needs to turn off the inverter, they can press the stop button, and the inverter will stop running. The power adjustment button allows the user to adjust the inverter's output power as needed. In some cases, the user may want to reduce the inverter's output power to save energy or reduce operating costs; in other cases, the user may need to increase the output power to meet higher power demands. The display operation button is usually used to view and set the inverter's operating parameters. By pressing this button, the user can enter the inverter's settings interface, view the current voltage, current, power, and other key parameters, and adjust them as needed.

[0038] In this embodiment, the display screen 15 and the limiting sleeve 121 protrude 2-3mm from the plane of the mounting plate 12, and the thickness of the housing 100 is also 2-3mm. When the control panel 1 is installed on the housing 100, the display screen 15 and the limiting sleeve 121 are flush with the mounting plate 12. Furthermore, the housing 100 is provided with a plurality of first through holes for the limiting sleeve 121 to be inserted, and the limiting sleeve 121 and the first through holes are on the same plane.

[0039] The housing 100 is provided with four downwardly extending connecting posts 101. The connecting posts 101 are hollow and have internal threads. The mounting plate 12 is provided with positioning posts 123. The positioning posts 123 are sleeved on the connecting posts 101 to position the mounting plate 12. The circuit board 11 is provided with a second through hole 111 for fasteners to pass through. The fasteners pass through the second through hole 111 and the connecting posts 101 in sequence to fix the circuit board 11, the mounting plate 12 and the housing 100 together.

[0040] In this embodiment, during assembly, a ring of sealant is first applied to the sealant layer 122 of the mounting plate 12. Then, the positioning post 1213 of the mounting plate is fitted onto the connecting post 101 of the housing 100. Next, the display screen 15 is secured to the mounting plate 12 using multiple hooks 16. Finally, screws and other fasteners are used to pass through the second through hole on the circuit board 11 and the connecting post 101 on the housing 100 to fix the circuit board 11 to the mounting plate 12 and / or the housing 100.

[0041] The control panel of this embodiment has at least the following advantages:

[0042] (1) The use of a touch part reduces the cost of use while ensuring a tight seal;

[0043] (2) The display screen 15 is held in place by a hook structure, which makes assembly more convenient and saves time.
