[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0026] Please refer to Figures 1-5 The utility model provides a kind of technical scheme: a glue filling type waterproof damage prevention inverter, including shell, mainboard 8 being installed in the shell inside and wifi antenna 7 located at one end of shell, by the setting of wifi antenna 7, make inverter have wireless transmission function, facilitate the wireless communication of this inverter, improve the convenience of use.

[0027] The outer casing includes a base 1, a first upper cover 2, and a second upper cover 6. The first upper cover 2 and the second upper cover 6 are installed side by side on top of the base 1. The first upper cover 2 and the second upper cover 6 are both connected to the base 1 by bolts. The first upper cover 2, the second upper cover 6, and the base 1 are all provided with screw holes for bolt installation. The first upper cover 2 and the second upper cover 6 are fixed to the base 1 by bolts, which facilitates the disassembly of the first upper cover 2 and the second upper cover 6 in sections according to usage and installation requirements, so as to facilitate the installation and maintenance of the internal components of the outer casing.

[0028] The base 1 has an internal baffle mechanism for surrounding the motherboard 8. A waterproof adhesive layer is applied to the surface of the motherboard 8 via a pouring method inside the baffle mechanism, completely covering the surface of the motherboard 8 during pouring. The upper surface of the waterproof adhesive layer is not flush with the upper surface of the baffle mechanism. Side plates 5 are installed on opposite sides of the first top cover 2. The first top cover 2 has through holes for installing the side plates 5, and the two side plates 5 are connected to the side walls of the first top cover 2 by screws. A display screen 3 is installed on the upper surface of the first top cover 2. Through the cooperation of the baffle mechanism and the motherboard 8, the surface of the motherboard 8 is completely covered by pouring waterproof adhesive inside the baffle mechanism. This waterproof adhesive increases the water resistance of the motherboard 8 and also protects the components on the motherboard 8, reducing damage to internal components caused by external impacts or drops, and improving the service life of the inverter.

[0029] The blocking mechanism includes two first blocking plates 10 and two second blocking plates 11. The two first blocking plates 10 and the two second blocking plates 11 alternately surround the motherboard 8. The second blocking plates 11 are fixed to opposite sides of the base 1. The two first blocking plates 10 are respectively inserted into the two ends of the second blocking plates 11. The first blocking plates 10 and the second blocking plates 11 form an orifice-shaped frame for applying waterproof adhesive to the motherboard 8. The orifice-shaped frame blocks the waterproof adhesive from overflowing from the motherboard 8 when applying it to the surface, allowing the waterproof adhesive to completely cover the motherboard 8 and form a protective layer on the motherboard 8 to protect the components on the motherboard 8.

[0030] The second baffle plate 11 has a slot 9 for the two side plates 5 to make way. The second baffle plate 11 and the base 1 are integrally formed, so that the second baffle plate 11 is located inside the first upper cover 2. Integrating the second baffle plate 11 and the base 1 into one piece can improve the firmness of the installation of the second baffle plate 11, and at the same time increase the sealing between the baffle mechanism and the base 1.

[0031] Both ends of the first baffle plate 10 are fixed with connecting blocks 14. The first baffle plate 10 and the two connecting blocks 14 form a U-shaped structure. The two ends of the second baffle plate 11 are provided with slots 13 for the connecting blocks 14 to be inserted. The two connecting blocks 14 are located above the first baffle plate 10, increasing the connection area with the second baffle plate 11. The U-shaped structure makes the upper surface of the first baffle plate 10 correspond to the upper surface of the base 1, preventing the waterproof glue from overflowing from the base 1 when it is poured. The first baffle plate 10 and the second baffle plate 11 are detachable. The first baffle plate 10 can be removed from the second baffle plate 11, and then the mainboard 8 with the waterproof glue layer can be removed, which facilitates the maintenance of the mainboard 8.

[0032] The blocking mechanism also includes a base plate 12, which is installed inside the base 1. The base plate 12 has positioning posts for mounting the main board 8. The length and width of the base plate 12 are the same as the length and width of the main board 8. The base plate 12 provides a limit for the installation of the main board 8. At the same time, the base plate 12 can also provide a certain degree of protection for the main board 8. When applying waterproof glue, it prevents the waterproof glue from being poured into the interior of the base 1 and thus sticking the main board 8 to the base 1.

[0033] One end of the base 1 is integrally formed with a protruding edge 4. The lower surface of the protruding edge 4 is not on the same plane as the lower surface of the base 1. The protruding edge 4 is provided with mounting holes, which facilitate the installation of the inverter in the designated installation position according to actual usage requirements, thereby improving the convenience of inverter installation.

[0034] The waterproof adhesive layer is an AB epoxy resin layer with a thickness of 1-3mm. After complete curing, the AB epoxy resin forms a dense cross-linked network structure with a smooth and tough surface, which can effectively improve the waterproof performance of the motherboard 8. The cured AB epoxy resin has high bonding strength and toughness, which can absorb the impact of drops to a certain extent, protecting the components of the motherboard 8 from damage caused by external factors such as moisture, insects, and drops. In addition, the thermal conductivity of AB epoxy resin is usually between 0.4-0.6W / (m·K), which gives it a certain heat dissipation effect and accelerates the heat dissipation rate of the motherboard 8.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
