Inverter shell

Technical Field

The utility model relates to an inverter technical field, in particular to inverter housing.

Background

The inverter is a converter which converts direct current electric energy (batteries and storage batteries) into constant-frequency constant-voltage or frequency-modulation voltage-regulation alternating current (generally 220V,50Hz sine wave). It is composed of inverter bridge, control logic and filter circuit. The existing inverter casing usually adopts a U-shaped casing, then the bottom plate and the side plate are locked on the casing through screws, and the internal circuit board is fixed on the casing. However, when the conventional housing is impacted by an external force, vibration is transmitted to the circuit board, which easily causes damage to the circuit board. In addition, the side plate is usually provided with an operation member such as a knob, and the side plate is likely to collide during use and to be damaged when a corner portion collides.

Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to 5, an inverter case of the present embodiment includes a first case 1, a second case 2, and a cushion 3, where the first case 1 has a convex portion 11, and extension plates 12 are provided on both sides of the convex portion 11. The second shell 2 has a bent part 21, the bent part 21 abuts against the extending plate 12, and the first shell 1 and the second shell 2 form a closed space. Be equipped with circuit board 4 in the enclosure space, shock pad 3 sets up between circuit board 4 and first casing 1, be connected through retaining member 5 between first casing 1 and the circuit board 4, be equipped with the interval space between circuit board 4 and the first casing 1. In the above technical solution, the bending portion 21 of the second housing 2 abuts against the extending plate 12 of the first housing 1, so that the first and second housings can be supported by each other, and the housing has better pressure resistance. Through setting up shock pad 3, can cushion the vibrations that the casing received, reduce vibrations and transmit for circuit board 4. Through the spacing space between circuit board 4 and first casing 1, when can first casing 1 pressurized, can have the buffer space, avoid the circuit board to be extruded. Through above-mentioned technical scheme, can make the casing have better structural strength, can strengthen the antidetonation buffer capacity of circuit board.

In this embodiment, the bent portion 21 has a U-shaped groove 22, the inverter housing includes a side plate 6, the side plate 6 has a positioning column 61, and the positioning column 61 is coupled with the U-shaped groove 22. Through above-mentioned technical scheme, can be convenient for the location installation between curb plate 6 and the second casing 2. In this embodiment, the corner of the side plate 6 is provided with the protection part 7, so that four corners of the side plate 6 are better protected, and the corner is not easy to damage when being impacted. In this embodiment, the protection portion 7 has a positioning column 71, the side plate 6 is provided with a positioning hole 62, and the positioning hole 62 is disposed corresponding to the positioning column 71, so that the protection portion 7 can be positioned and installed on the side plate 6. In this embodiment, the protection portion 7 is L-shaped. In this embodiment, the surface of the side plate 6 is provided with the protective film 8, and the protective film 8 is located between the protective part 7 and the side plate 6, so that the protective part 7 can fix the protective film 8 on the surface of the side plate 6, and the protective film is not easy to fall off.
