Description

Technical Field

[0001] This utility model relates to the field of DC power supply technology, and in particular to a power supply structure. Background Technology

[0002] A DC power supply is a device that converts raw electrical energy, such as alternating current (AC) or batteries, into a stable direct current (DC) output. It is widely used in industries, communications, laboratories, consumer electronics, and other fields. Its main principle is to use internal transformers and rectifier bridges to step down, rectify, filter, and linearly regulate the voltage.

[0003] Some transformers can have their pins securely soldered to pads via wave soldering or manual soldering, or fixed to the housing with bolts. For example, Chinese Patent Publication No. "CN218826484U" discloses a power transformer belonging to the field of power equipment technology. This transformer includes a housing, with connecting components on the sides and a top plate connected to the top. The top plate has a through-hole, and a sealing component connects to the side of the through-hole. This invention, by setting the connecting components, allows the top plate, side plates, and housing to be rotatably connected, enabling the top and side plates to be rotated open, exposing the housing and facilitating installation and wiring of the transformer body, as well as future maintenance. The sealing component, under the elastic force of spring two, allows the sliding plate to seal the through-hole in the top plate, preventing dust from entering the housing and interfering with the transformer body. The wire harness groove on the flexible plate at the side of the sliding plate also limits and fixes the wires, preventing dust entry and also limiting the wire movement.

[0004] In actual operation, considering that the iron core of the transformer will undergo magnetostriction under the action of alternating magnetic field when it is operating, producing a slight vibration, this is the reason for the humming sound. Because the lack of a fixed structure can easily affect the tightness of the transformer connection over a long period of time, and if the transformer needs to be replaced or repaired, all fixing screws must be completely unscrewed, which greatly increases the difficulty and time cost of maintenance. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the lack of a structure to reinforce the transformer and the inconvenience of disassembling and fixing the transformer, and to propose a power supply structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a power supply structure including a chassis, the chassis being composed of a housing and a top cover, the top cover being fixedly connected to the top of the housing and forming an opening, a display panel being fixedly connected to the opening of the chassis, and a heat dissipation assembly and a transformer assembly being installed inside the chassis. The transformer group includes several fixing plates corresponding to the transformer, and the fixing plates are fixed to the housing through a fixing structure to fix the transformer.

[0007] Furthermore, the heat dissipation assembly includes an output heat sink and an input heat sink, which are disposed on both sides of the transformer group, and both the output heat sink and the input heat sink are fixedly connected to the bottom of the housing.

[0008] Furthermore, a fan assembly is fixedly connected inside the housing on the same side as the output heat sink and the input heat sink, wherein an air inlet and an air outlet are respectively provided between the housing and the display panel.

[0009] Furthermore, the fixing structure includes connectors, and the inner bottom of the housing is fixedly connected to the two sides of the transformer. The connectors are U-shaped, with their two ends bent outwards to form bends. The two ends of the connectors are deformed under force so that the bends are movably connected to the fixings.

[0010] Furthermore, a stop is fixedly connected to the end of the connector, and the stop stops the protrusion on the side of the fixing member near the transformer.

[0011] Furthermore, buffer pads are provided on the upper and lower sides of the transformer, and the fixing plate is provided on the top of the transformer. The two sides of the fixing plate form elastic stop parts through deformation grooves. The connecting piece slides against the elastic stop parts to stop in the deformation grooves.

[0012] The power supply structure proposed in this utility model has the following advantages: an input and an output heat sink are provided inside the chassis. The two heat sinks, together with the fan assembly, can absorb and dissipate the heat generated by the operation of the power supply components inside the chassis, preventing temperature buildup from affecting the normal operation of the power supply. In addition, the two connecting parts in the fixed structure, together with the fixing plate, can further improve the stability of the transformer fixing, or replace the bolt fixing method to realize the convenient assembly and disassembly of the transformer. Furthermore, the two connecting parts and the fixing plate can be disassembled by unlocking the elastic stop, which is convenient, quick and highly practical. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A power supply structure includes a chassis 1, which is composed of a housing 11 and a top cover 12. The top cover 12 is fixedly connected to the top of the housing 11 and forms an opening. A display panel 2 is fixedly connected to the opening of the chassis 1, and a heat dissipation assembly 3 and a transformer assembly 4 are installed inside the chassis 1. The transformer group 4 includes several fixing plates 42 corresponding to the transformer 41. The fixing plates 42 and the housing 11 are fixed to the transformer 41 by a fixing structure 5.

[0017] In some embodiments, the power supply structure can refer to the DC power supply device in the prior art. The DC power supply device generally includes an input protection and filtering section, a power conversion section, an output rectification and filtering section, a control and feedback section, etc. Multiple parts are connected by electrical connection and signal feedback to form a closed loop system. The specific connection method and specific structure are all prior art and will not be described in detail here. Among them, the heat dissipation component 3 is used to absorb and dissipate the heat generated between the multiple parts.

[0018] Furthermore, the heat dissipation component 3 includes an output heat sink 31 and an input heat sink 32. The output heat sink 31 and the input heat sink 32 are disposed on both sides of the transformer group 4, and both the output heat sink 31 and the input heat sink 32 are fixedly connected to the bottom of the housing 11.

[0019] Furthermore, inside the housing 11, on the same side as the output heat sink 31 and the input heat sink 32, a fan assembly 33 is also fixedly connected. An air inlet and an air outlet are respectively provided between the housing 11 and the display panel 2.

[0020] In this embodiment, the input heat sink 32 is mainly responsible for dissipating heat from the high-voltage section at the front end, protecting key components such as the rectifier bridge and PFC switch. The output heat sink 31 is responsible for heat management of the low-voltage, high-current section at the back end, focusing on the output rectifier and filter inductor. The output heat sink 31 and the input heat sink 32 are used to absorb the temperature generated by the components, and together with the fan assembly 33, the temperature is discharged to the outside of the chassis 1 through the exchange of internal and external air.

[0021] More specifically, the fixing structure 5 includes a connector 51. The inner bottom of the housing 11 is fixedly connected to the two sides of the transformer 41 with fixing members 52. The connector 51 has a U-shaped structure, and its two ends are bent outward to form a bending part 53. The two ends of the connector 51 are deformed under force so that the bending part 53 is movably connected to the fixing member 52.

[0022] In general, a stop 54 is fixedly connected to the end of the connector 51, and the stop 54 stops the protrusion of the fixing member 52 on the side near the transformer 41.

[0023] Finally, buffer pads 43 are provided on the upper and lower sides of the transformer 41, and the fixing plate 42 is provided on the top of the transformer 41. The two sides of the fixing plate 42 form elastic stop parts 45 through deformation grooves 44. The connecting member 51 slides against the elastic stop parts 45 to stop in the deformation grooves 44.

[0024] In some embodiments, the stability of the transformer 41 is further improved by the fixing structure 5, and the connection 51 in conjunction with the fixing plate 42 can replace the bolt fixing method, thereby further improving the disassembly and assembly efficiency. In this embodiment, as Figure 2 , 3 As shown in Figures 4 and 5, the transformer 41 is positioned between two connecting pieces 51. After the fixing plate 42 is positioned above the transformer 41 and the buffer pad 43, the connecting piece 51 is rotated half a turn. On one hand, the stop 54 at the end of the connecting piece 51 stops the protrusion on the side of the fixing piece 52 near the transformer 41. On the other hand, while the connecting piece 51 rotates, its middle position slides against the elastic stop 45. Then, the elastic stop 45, in conjunction with the deformation groove 44, locks and fixes the connecting piece 51. The connecting pieces 51 on both sides then use tension to drive the fixing plate 42 to press the transformer 41, thereby achieving a reinforcement effect. It is worth mentioning that, such as Figure 5 As shown, the fastener 52 is formed by stamping a metal plate and is used to limit the connector 51. Both the connector 51 and the fastener 42 are preferably made of materials with elastic deformation capabilities, such as stainless steel. The connector 51 is squeezed to deform its end, and then it can be connected to the fastener 52. Specifically, under normal circumstances, due to the rotation stop of the stop 54 and the fixing 52, after the two connecting parts 51 are fixed to the fixing plate 42, the two connecting parts 51, the fixing plate 42 and the box 11 form a rectangular structure, which improves the lateral force bearing capacity of the fixing structure 5. Of course, the fixing plate 42 itself has a certain rigidity to prevent the fixing from being unstable. Reference Figure 4 It can be seen that by moving the movable end of the elastic stop 45, it can be slightly deformed, thereby unlocking the connector 51.

[0025] In addition, the cushioning pad 43 is usually made of insulating material and plays a cushioning and protective role. Pin holes can also be reserved on the cushioning pad 43.

[0026] Working method: The transformer 41 is placed between two connectors 51, and the fixing plate 42 is placed above the transformer 41 and the buffer pad 43. The connector 51 is rotated half a turn so that the stop 54 stops the protrusion of the fixing plate 52 near the transformer 41. Then, while the connector 51 is rotating, its middle part slides against the elastic stop 45. Then, the elastic stop 45 cooperates with the deformation groove 44 to lock and fix the connector 51. The two connectors 51 on both sides drive the fixing plate 42 to press the transformer 41 with tension to achieve the reinforcement effect. The heat absorbed by the output heat sink 31 and the input heat sink 32 can be discharged from the inside of the chassis 1 through the exchange of internal and external air by the fan assembly 33.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
