[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0027] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, and are hereby explained together.

[0028] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs. Embodiment

[0029] As Figures 1 to 6 shown,

[0030] This embodiment includes:

[0031] A box body 1 made of ultra-thin light metal for power distribution and control. The overall structure of the box body 1 of this chassis adopts a new type of ultra-thin light metal. That is, light metal refers to a metal with a relative density less than 5. For example, it is made of magnesium alloy to reduce the mass of the box body 1 itself, facilitate movement, installation and disassembly, and is easy to use. It not only has high strength but also is light in weight, facilitating handling during installation.

[0032] On both sides of the box body 1, air outlets 2 for facilitating internal heat dissipation are symmetrically arranged. A shielding edge is provided at the air outlet 2 on the outer side wall of the box body 1. The setting of the edge enables the device to not only reduce rainwater from entering the inside of the box body 1 when fixed outdoors, but also reduce the entry of impurities such as dust from the outside into the box body 1 in windy weather. On one side of the box body 1, a movable groove 7 is provided, and a box door 3 hinged by a hinge is arranged in the movable groove 7, facilitating inspection and maintenance inside the box body 1.

[0033] Multiple movable plates 5 for facilitating the installation of power control electronic components. The movable plate 5 is threadedly connected to a threaded rod 6 capable of adjusting multiple lifting speeds. Different pitches of threads are provided on the outer peripheral side of the threaded rod 6. The setting of different pitches of threads can effectively adjust the spacing of the movable plate 5 according to the usage situation.

[0034] One end of the threaded rod 6 is rotatably connected to the inner top wall of the box body 1, and the other end of the threaded rod 6 penetrates the inner bottom wall of the box body 1 and is connected to the output shaft of the drive motor. The fixing part of the drive motor is screw-connected to the bottom of the box body 1. By controlling the rotation of the drive motor, the threaded rod 6 is driven to rotate, and the spacing of the movable plate 5 is adjusted. On the inner wall of the other side of the box body 1, round rods 10 with a smooth outer peripheral side corresponding to the threaded rod 6 one by one are welded. The round rod 10 is slidably connected to the movable plate 5, and both ends of the round rod 10 are fixed to the inner wall of the box body 1. The setting of the round rod 10 makes the movable plate 5 more stable during movement, facilitating the electronic components fixed on the top of the movable plate 5 to be more stable.

[0035] In order to prevent the dust in the outside air from corroding the electronic components connected to the movable plate 5 during heat dissipation, slide rails 9 are provided on the inner wall of the box body 1. The slide rails 9 are arranged on both sides of the air outlet 2. A T-shaped slide plate 12 is slidably connected to the slide rails 9. The end of the slide plate 12 is welded to the side wall of the filter box 8. A filter screen is embedded and installed on the side wall of the filter box 8. The filter box 8 is arranged with an opening on one side of the inner wall of the box body 1, facilitating the airflow circulating inside the box body 1 to pass through, thereby dissipating the heat generated by the electronic components installed inside the box body 1.

[0036] On the top of the box body 1, symmetric connecting grooves 13 are also provided. The connecting grooves 13 are located directly above the filter box 8. A fixing layer for facilitating connection is arranged in the connecting grooves 13. The top of the fixing layer abuts against a movable plate 4 that is convenient for moving. Symmetrically arranged grooves for facilitating force application are provided on the top of the movable plate 4. By gripping the handle 11 arranged on the top of the movable plate 4 through the grooves and taking it out, the filter box 8 installed inside the slide rail 9 can be taken out regularly to clean and replace the installed filter screen, which is convenient for use.

[0037] Working principle

[0038] For this new type of ultra-thin light metal chassis, when the operator uses the device, the box body 1 made of ultra-thin light metal is fixed. When installing the electronic components for control, first, the movable plate 4 is opened through the grooves. The filter box 8 with a filter screen fixed is connected to the slide rail 9 through the slide plate 12, and the filter box 8 is connected to the box body 1 through the connecting groove 13, and then the movable plate 4 is reset. Finally, according to the actual use situation inside the box body 1, the driving motor arranged at the bottom of the box body 1 is controlled to rotate, driving the connected threaded rod 6 to rotate, adjusting the distance between the moving plates 5 connected at different pitches, and then fixing the electronic components for control to the moving plates 5, and closing the box door 3 hinged by the hinge.
