Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a vertical power supply chassis. Background Technology

[0002] In a CT scanner, the power supply unit is used to convert externally input AC power into various isolated and stable DC or AC voltages to power subsystems such as the X-ray high-voltage generator, detector array, slip ring, rotary drive motor, control computer, and cooling pump.

[0003] In order to improve space utilization, existing CT scanners generally adopt a "rotation-fixed" double-layer frame structure. The inner frame carries the X-ray tube and detector and rotates at high speed with the slip ring; the outer frame fixes components such as the high-voltage generator, heat exchanger, and power supply chassis. Due to limitations in slip ring diameter, scanning aperture, and overall machine height, the outer frame has only narrow gaps of less than 200mm in both radial and axial directions for accommodating the power supply chassis. Furthermore, the outer frame is often a truss structure welded from aluminum profiles, with intersecting longitudinal and transverse reinforcing ribs, further resulting in an irregular geometric shape of usable space. The mounting surface is often divided into several small sections by beams and diagonal braces, making it difficult to provide a complete and continuous planar mounting surface.

[0004] Existing CT scanners typically use horizontal or wall-mounted power supply chassis. Horizontal chassis require at least four bolts at the bottom and sides to secure them to the frame beams. Inconsistent beam spacing or incomplete mounting surfaces necessitate the use of adapter plates, easily increasing the overall thickness of the machine and exceeding the allowable profile of the CT scanner's casing. Wall-mounted power supply chassis, due to the irregular geometry of the CT scanner's internal space, often cannot fully utilize the mounting holes on the back, leading to loosening after installation.

[0051] The technical solution of this utility model will be described in detail below with reference to specific embodiments and the accompanying drawings.

[0052] As attached Figure 1 - Appendix Figure 6 As shown in an illustrative embodiment of a vertical power supply chassis according to this utility model, the power supply chassis is installed in a CT scanner. The CT scanner adopts a "rotation-fixed" double-layer frame structure, and its frame has a crisscrossing reinforcing rib structure. The power supply chassis includes a first housing 1, a first transformer, a first electronic component assembly 2, and a support assembly 3.

[0053] The first enclosure 1 is a rectangular metal cover assembled from a top plate and at least three side plates. After assembly, the bottom of the first enclosure 1 has a lower opening so that the transformer can be inserted from below.

[0054] The first transformer is fixed inside the first enclosure 1 by bolts. It should be noted that the first transformer is installed inside the first enclosure 1, and is not shown in the figure.

[0055] The first electronic device assembly 2 includes multiple electronic devices, each of which is mounted on the outer side wall of the first housing 1 to disperse heat sources and reduce internal temperature rise.

[0056] The support assembly 3 includes a support plate 31 and a support frame 32.

[0057] The support plate 31 is a rectangular sheet metal plate that completely covers the lower opening end of the first housing 1 and is fastened to the first housing 1 with screws to achieve encapsulation of the first housing 1. Two hooks 33 are pre-machined on the bottom end face of the support plate 31.

[0058] The support frame 32 is U-shaped with the opening facing downwards. A slot 323 is provided on the top end face of the support frame 32. The hook 33 of the support plate 31 is inserted into the slot 323 of the support frame 32 to form a detachable snap-fit ​​with the support plate 31.

[0059] When installing the power supply chassis, the restricted support frame 32 is inserted into the reserved narrow gap of the CT machine's outer frame and fixed. Then, the entire assembly connecting the first housing 1 and the support plate 31 is inserted from top to bottom, so that the hook 33 automatically slides into the slot 323 to complete the positioning and locking.

[0060] In the above illustrative embodiment, by installing a support frame 32 at the bottom of the power supply chassis, the mounting surface of the power supply chassis is transferred from the perimeter of the chassis to the support frame 32. Simultaneously, the shape of the support frame 32 can be adjusted according to the orientation of the CT machine frame and the shape of the reserved installation gap, thus avoiding the crisscrossing beams, vertical beams, and diagonal beams within the CT machine's internal frame structure. Furthermore, the insertion method of the hooks 33 and slots 323 in the support assembly 3 eliminates the need for tools during assembly and disassembly, significantly improving maintenance efficiency.

[0061] To improve the overall strength of the support frame 32, in some embodiments of this utility model, the support frame 32 is integrally bent from a single sheet metal plate, including at least two vertical support parts 321, which are connected by a transverse connecting part 322. The transverse connecting part 322 is provided with a slot 323 for connecting with the hook 33 of the support plate 31.

[0062] To reduce the volume of the support frame 32 and adapt to the limited installation space inside the CT scanner, in some embodiments of this invention, the area of ​​the transverse connecting portion 322 in the support frame 32 is smaller than the area of ​​the support plate 31. At least one side of the support plate 31 is bent downwards at a 90° angle near the edge of the vertical support portion 321 to form a folded edge 311.

[0063] A sheet metal filler 34 is provided between the vertical support portion 321 and the folded edge portion 311. The thickness of the sheet metal filler 34 is equal to the gap width between the vertical support portion 321 and the folded edge portion 311.

[0064] In order to fix the filler 34, in some embodiments of the present invention, two hooks 33 are provided on the end face of the filler 34 near the vertical support 321.

[0065] The vertical support part 321 is provided with a slot 323 at the corresponding position. During installation, the hook 33 of the filler 34 is inserted into the slot 323 of the vertical support part 321 and engages with the vertical support part 321. Then, it is attached and fixed to the folded edge 311 of the support plate 31 to improve the stability of the connection.

[0066] In order to mount electronic devices on the outer wall of the first housing 1, some embodiments of the present invention further include a device mounting plate 4.

[0067] The device mounting plate 4 is disposed on the outer wall of the first housing 1, and the first electronic device assembly 2 is mounted on the outside of the first housing 1 through the device mounting plate 4.

[0068] The device mounting plate 4 has at least one edge bent toward the edge away from the first housing to form a bend 41, in order to protect the device mounting plate 4 and prevent the electronic device from interfering with other structures inside the CT machine.

[0069] In order to reduce material costs, in some embodiments of this utility model, the device mounting plate 4 is part of the outer wall of the box.

[0070] To improve the overall strength of the chassis, in some embodiments of this utility model, the top plate and at least three side plates are integrally bent and formed.

[0071] In order to improve the heat dissipation performance of the power supply chassis and reduce the risk of failure caused by transformer overheating, in some embodiments of this utility model, the top plate and at least three side plates are provided with heat dissipation holes.

[0072] In order to further improve the heat dissipation performance of the power supply chassis, in some embodiments of this utility model, heat dissipation holes are opened at corresponding positions of the first housing 1 on the support plate 31.

[0073] In order to hoist the power supply chassis, some embodiments of this utility model further include four eye bolts 5, which are respectively fixedly installed on the top of the first chassis 1 through the top plate.

[0074] In some embodiments of the present invention, the first electronic device assembly 2 includes at least a contactor 21, a circuit breaker 22, and a terminal block 23.

[0075] Terminal block 23 is connected to the first transformer. The output terminal of the first transformer is connected to the input terminal of circuit breaker 22. The output terminal of circuit breaker 22 is connected to the output terminal of contactor 21.

[0076] To improve the expandability of the power supply chassis, some embodiments of this utility model further include a second chassis 6, a sliding mounting assembly 7, and a second electronic component assembly 8.

[0077] Among them, the sliding installation component 7 is slidably installed on the second housing 6.

[0078] The second electronic component assembly 8 is mounted on the sliding mounting assembly 7 and the second housing 6. The second electronic component assembly 8 includes at least a filter, the output of which is connected to the first transformer via a terminal block 23.

[0079] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
