[0026] See also Figure 1 and Figure 2The high-voltage power supply device 1000 includes a first housing 100, a high-voltage module 200 and a functional module 300. The first housing 100 is provided with a first receiving cavity 110. The high-voltage module 200 includes a second housing 210, a high-voltage circuit 220 and an insulating rubber layer 230. The second housing 210 is detachably fixed to the first housing 100 and received in the first receiving cavity 110. The second housing 210 is provided with a second receiving cavity 213. The high-voltage circuit 220 is received in the second receiving cavity 213. The insulating rubber layer 230 fills the second receiving cavity 213, and the insulating rubber layer 230 covers the high-voltage circuit 220. The functional module 300 is received in the first receiving cavity 110. The functional module 300 is separated from the high-voltage module 200 and is electrically connected to the high-voltage module 200. The present application adopts the above structure to separately perform glue filling treatment on the high-voltage module 200, so that the insulating glue layer 230 is filled in the second receiving cavity 213, so as to achieve the purpose of insulating the high-voltage module 200, without filling the first receiving cavity 110 with insulating material as a whole. On the one hand, when part of the internal structure of the high-voltage power supply device 1000 is damaged, it can be separately disassembled and processed. For example, when the high-voltage module 200 is damaged, the high-voltage module 200 is separately removed and replaced, or the insulating glue layer 230 in the second receiving cavity 213 is removed to repair the high-voltage circuit 220; or, it is convenient to repair, replace, or upgrade the hardware and software of the functional module 300 of the high-voltage power supply device 1000; on the other hand, the volume of the second shell 210 is smaller than that of the first shell 100, so as to facilitate the filling and transportation of the second shell 210. It is worth mentioning that in order to facilitate the installation of the high-voltage power supply device 1000 in the external rack equipment, the first shell 100 is in the shape of a flat rectangular parallelepiped. In the first receiving cavity 110, the functional module 300 and the high-voltage module 200 are separated and arranged in order to perform partitioned modular assembly in the high-voltage power supply device 1000, so as to facilitate installation and disassembly, batch production and improve work efficiency. Optionally, when the high-voltage power supply device 1000 is assembled, the high-voltage circuit 220 is first installed in the second housing 210, and then the insulating rubber layer 230 is filled in the second receiving cavity 213, and finally the assembled high-voltage module 200 is installed in the first housing 100.

[0027] For the first housing 100, see Figures 2 to 4 The first shell 100 includes an end cover 120, a side plate 130 and a base plate 140, and the end covers 120, the two side plates 130 and the two base plates 140 together enclose the first receiving cavity 110. The second shell 210 is installed on the side plate 130. Specifically, the second shell 210 is in contact with one of the side plates 130 and one of the base plates 140, and the side plate 130 and the base plate 140 are two adjacent surfaces of the first shell 100, so as to facilitate the installation and fixing of the second shell 210 and prevent the high-voltage module 200 from loosening. There is a gap between the second shell 210 and the end covers 120.

[0028] Further, please refer to Figure 2 , and in combination with other attached drawings. The first housing 100 further includes a fixing component 150. The fixing component 150 includes a fixing plate 151 and a handle 152. The fixing plate 151 protrudes relative to the side plate 130 along the direction in which the end cover 120 extends. The fixing plate 151 is provided with a fixing hole 1511. The handle 152 protrudes relative to the end cover 120 in a direction away from the first receiving cavity 110. It can be understood that the fixing hole 1511 is set as a "U"-shaped hole, so as to facilitate adjusting the set position when the first housing 100 is installed on other rack devices, and prevent the first housing 100 from being inconvenient to install due to errors in part manufacturing. The handle 152 is provided to facilitate pushing or pulling the first housing 100 relative to other rack devices. It can be understood that the handle 152 is set as a "冂"-shaped handle 152, so as to facilitate gripping. Optionally, the handle 152 can be folded and stored relative to the end cover 120, so as to prevent the handle 152 from interfering with other devices. It should still be noted that in the embodiment of the present application, the fixing plate 151 and the end cover 120 are integrally formed, thereby improving the manufacturing efficiency of the workpiece and improving the installation strength and structural strength of the end cover 120.

The high-voltage circuit 220 is installed in the high-voltage housing 212. Specifically, the second housing 210 is integrally in a cuboid shape, so as to adapt to the inner contour of the first receiving cavity 110, thereby improving the space utilization rate of the first receiving cavity 110 and reducing space waste.

[0030] Further, please refer to Figures 2 to 4. The projections of the high-voltage cover plate 211 and the high-voltage housing 212 on the side plate 130 at least partially overlap.

That is, the locking member 400 passes through the side plate 130 and the high-voltage housing 212, thereby fixing the second housing 210 to the first housing 100, and the locking member 400 passes through the high-voltage cover plate 211 and the high-voltage housing 212, thereby installing and fixing the second housing 210. Optionally, in some embodiments, the high-voltage housing 212 can also be fixed to the second housing 210, and another locking member 400 is used to fix the high-voltage housing 212 and the high-voltage cover plate 211. It is worth mentioning that the projections of the high-voltage cover plate 211 and the high-voltage housing 212 on the side plate 130 at least partially overlap, so as to allow the locking member 400 to pass through for installation and fixing.

[0031] For further information, see Figures 2 to 4 The high-pressure housing 212 is provided with a first fixing portion 2121, which is concave away from the side plate 130, and the high-pressure cover plate 211 is provided with a second fixing portion 2111, and the projections of the first fixing portion 2121 and the second fixing portion 2111 on the side plate 130 overlap. Through the above structure, the outer surface of the second housing 210 is flat, so as to prevent the overlapping part of the high-pressure housing 212 and the high-pressure cover plate 211 from occupying the space of the first receiving cavity 110.

[0032] For further information, see Figure 3 The high-pressure cover plate 211 has a first end 2112 close to one end cover 120, and the high-pressure housing 212 has a second end 2122 close to one end cover 120, and a gap is left between the first end 2112 and the second end 2122.

The output cable 250 is plugged into the second receiving cavity 213, and the output cable 250 passes through the first receiving cavity 110 and extends outside the first housing 100. Specifically, the communication board 240 is at least partially exposed in the above-mentioned gap, the communication board 240 and the high-voltage housing 212 jointly enclose the second receiving cavity 213, and the output cable 250 is arranged on a side away from the handle 152, so as to output high voltage electricity to other electrical equipment.
