Description

Technical Field

[0001] The present invention relates to the technical field of outdoor inverter accessories, and in particular to a housing with a waterproof operation panel and an inverter. Background Art

[0002] With the vigorous development of the photovoltaic new energy industry in recent years, grid-connected energy storage photovoltaic inverters have become key equipment in this industry chain. Therefore, improving the safety, service life, and stability of inverters is of great significance. However, most inverters are installed in harsh environments, often facing high temperatures, rain, wind and sand, and other outdoor conditions. Therefore, a high level of protection is usually required to improve the safety, service life, and stability of the inverter.

[0003] Currently commonly used display schemes are:

[0004] 1. Non-touch screen + button: This type relies on buttons for operation, and waterproofing is mostly achieved by applying a film to the outer surface. Disadvantages of this method: Because the product is installed outdoors, the film is easily damaged over time and the appearance is slightly poor. The adhesive backing is easily ineffective after long-term exposure to sunlight and rain, making waterproofing unreliable and providing a poor customer experience.

[0005] 2. Touchscreen displays: These rely on touchscreen operation, and waterproofing is mostly achieved through a film applied to the exterior surface. Disadvantages of this method include: operating the screen through the film provides a poor user experience. Because the product is installed outdoors, the film is easily damaged over time, and the appearance is slightly poor. The adhesive backing can easily lose effectiveness after prolonged exposure to sunlight and rain, making waterproofing unreliable. If the touchscreen fails to function, it cannot be operated, resulting in a poor customer experience. Summary of the Invention

[0069] The shell with a waterproof operation panel described in the embodiment integrates light guide, waterproofing, and keys into one. When the display screen 500 uses a touch screen, it belongs to an inverter waterproof structure with exposed touch screen and backup keys. It can be directly touched to operate the display screen 500 or operated through the key 920. The shell has strong waterproof reliability, is easy to operate, has backup keys 920, and can be operated through the keys in the case of touch screen failure.

[0070] Referring to Figures 1-4As shown, in the optional solution of the embodiment, the two surfaces of the light guide waterproof key integrated piece 400 correspondingly are provided with sealing protrusions 440; the sealing protrusions 440 are annular; the light guide protrusions 410 and the key protrusions 420 are located in the annular space of the sealing protrusions 440; the heights of the light guide protrusions 410 and the key protrusions 420 protruding from the body of the light guide waterproof key integrated piece 400 are higher than the height of the sealing protrusions 440 protruding from the body of the light guide waterproof key integrated piece 400; by providing the two surfaces of the light guide waterproof key integrated piece 400 correspondingly with the sealing protrusions 440, the waterproof performance of the light guide protrusions 410 and the key protrusions 420 is improved, and the waterproof performance of the indicator lamp 910, the key 920 and the display screen 500 is further improved. When the first fastener 700 fastens and connects the mounting bracket 600 and the shell 100, the sealing protrusions 440 are deformed by extrusion to improve the waterproof sealing performance.

By setting the integrated piece fastener hole 480 outside the annular space of the sealing protrusions 440, it is prevented that the integrated piece fastener hole 480 affects the waterproof performance of the light guide waterproof key integrated piece 400.

[0073] Referring to Figures 1-4 As shown, in the optional solution of the embodiment, the light guide protrusions 410 and the key protrusions 420 protrude in the direction away from the support body 900; the light guide protrusions 410 are provided with light guide protrusion cavities 411 on the side close to the support body 900, and at least part of the indicator lamps 910 are accommodated in the light guide protrusion cavities 411; the key protrusions 420 are provided with key protrusion cavities 421 on the side close to the support body 900, and at least part of the keys 920 are accommodated in the key protrusion cavities 421; by accommodating at least part of the indicator lamps 910 in the light guide protrusion cavities 411, the light guide protrusions 410 guide the light of the indicator lamps 910 out, realizing the light display effect. By accommodating at least part of the keys 920 in the key protrusion cavities 421, the force can be transmitted to the keys 920 by pressing the key protrusions 420, realizing the functional operation of the keys 920.

[0074] Optionally, the integrated light-guiding waterproof keypad component 400 is made of silicone or other materials. For example, the integrated light-guiding waterproof keypad component 400 is made of transparent silicone. Optionally, a light diffuser is added to the silicone; for example, using existing technology, a silicone-specific light diffuser, GJST-5, is added to the silicone at a ratio of 8%. This makes the finished integrated light-guiding waterproof keypad component 400 translucent, providing excellent light-guiding and sealing properties.

[0075] See also Figure 5 and Figure 6 As shown, in an optional solution of this embodiment, a first groove 630 and a second groove 640 are provided on a side of the mounting bracket 600 close to the housing 100, and an annular rib 690 is formed between the first groove 630 and the second groove 640; the second groove 640 is located on the outer periphery of the first groove 630, that is, the first groove 630 is located inside the second groove 640.
