Referring to fig. 1, 2 and 3, the present application provides a housing assembly 100 that may be used as a housing for a mechanical or electrical device (hereinafter referred to simply as a "device", such as an air conditioner external unit 200 described below) for protecting mechanical as well as electrical components within the device.

The housing assembly 100 includes a housing 10 and an electronic control box 30. The housing 10 is a main body portion of the housing assembly 100, and may have a substantially rectangular parallelepiped shape, for example. The housing 10 may be made of stainless steel or thermoplastic, which has good weather resistance and stability, and can effectively protect devices disposed inside the housing 10. The housing 10 is provided with an inner cavity (not shown in the drawings) and a through hole 11 communicating with the inner cavity. The inner cavity is for mounting and accommodating electrical components of the apparatus, and the through hole 11 is opened on one surface of the housing 10.

The electronic control box 30 is an electronic controller of the device that primarily controls the operation of the electrical components in the interior cavity. The electronic control box 30 mainly comprises a microprocessor, a power supply, an input/output interface, a protection circuit and other components, and the components work cooperatively to control the normal operation of the equipment.

The electronic control box 30 includes a box body 301 and a cover body 302. The box 301 is a structure of the electronic control box 30 for accommodating components such as a microprocessor, a power supply, a protection circuit, and the like. The box 301 is disposed in the inner cavity and connected to the housing 10. The shape of the case 301 is not limited, and may be, for example, a substantially rectangular parallelepiped shape provided with a mounting chamber 303. The mounting chamber 303 penetrates one side of the case 301 to form a mounting opening 304, the mounting opening 304 corresponds to the position of the through hole 11, and the mounting opening 304 is exposed to the housing 10 through the through hole 11. With the above arrangement, a worker can repair or replace parts inside the installation cavity 303 via the through hole 11 and the installation port 304. The cover 302 is a structure of the electronic control box 30 for covering the box 301, the cover 302 is disposed outside the housing 10 and covers the through hole 11 and the mounting opening 304, and the cover 302 is detachably connected to the housing 10. In the embodiment shown in the drawings of the present specification, the cover 302 is connected to the housing 10 by bolts, which is only used herein as an example and not by way of limitation, and the cover 302 may be detachably connected to the housing 10 by other means, such as a snap fit connection with a slot.

With the above arrangement, since the mounting opening 304 corresponds to the position of the through hole 11, and the cover 302 covers the mounting opening 304, the cover 302 can close the case 301, thereby protecting the components inside the case 301. Because the cartridge 301 is located in the interior cavity and is not directly exposed to the exterior surface of the housing 10, the volume of the device can be reduced, avoiding excessive bulk of the device as a whole. And because the box body 301 is positioned in the inner cavity, the chance of the box body 301 contacting with rain and snow is greatly reduced, thereby greatly reducing the possibility of water inflow of the box body 301 and playing a role in improving the waterproof performance of the electric control box 30. In summary, the housing assembly 100 provided in the embodiment can reduce the volume of the device, avoid the device from being excessively bulky, and improve the waterproof performance of the electronic control box 30, and is stable and reliable.
