[0040] Reference Figures 1-4 This embodiment provides a frame structure for a charging and discharging integrated machine, including a body housing assembly, a support frame assembly 2, and an electrical component assembly;

[0041] The support frame assembly 2 includes a support component 20 and a support plate assembly. The support plate assembly is arranged in a multi-layer structure on the support component 20 to form a layered accommodating space.

[0042] The fuselage housing assembly is mounted on the support plate assembly and connected to the support assembly 20. The electrical component assembly is disposed within the receiving space and is electrically connected to the fuselage housing assembly.

[0043] In the above embodiments, the frame structure of the charging and discharging integrated machine includes a housing assembly, a support frame assembly 2, and an electrical component assembly. The support frame assembly 2 serves as the load-bearing and layout foundation of the entire structure, constructing a stable internal space system. The support component 20 is the vertical load-bearing structure within the support frame assembly 2, providing vertical support and connecting the various layers. The support plate assembly is mounted on the support component 20, forming a multi-layered, vertically separated three-dimensional structure with a certain distance between each layer, thus creating multiple independent storage spaces. These storage spaces are axially arranged along the same axis, forming a shelf-like hierarchical structure, providing physical partitioning for the orderly installation of internal components.

[0044] The housing assembly is mounted on the outside of the support plate assembly and rigidly connected to the support assembly 20. Electrical component assemblies are rationally distributed within their respective compartments according to function and wiring requirements, ensuring clear wiring paths and preventing interference between components. The compartments are interconnected via the support assembly 20, facilitating longitudinal cable routing. The support frame assembly 2 is centrally located, with the housing assembly covering the outside, achieving enclosure and interface integration. Electrical component assemblies are housed within their internal compartments and electrically connected to the housing assembly via wires, enabling power and signal transmission. This multi-layered support plate assembly creates layered compartments, avoiding simple component stacking, organizing the internal layout, and making the installation and wiring of electrical components more orderly, reducing wiring difficulty. Furthermore, the layered structure allows for precise component location during maintenance, reducing disassembly and assembly interference, simplifying maintenance processes, improving equipment operation and maintenance convenience, effectively increasing maintenance efficiency, and adapting to the maintenance needs of new energy vehicles.

[0045] Reference Figure 1 , Figure 4 In one embodiment, the support component 20 consists of multiple support columns, and the support plate component includes a base plate 210, a first support plate 211, and a second support plate 212. The multiple support columns are arranged in an array and fixedly connected to the base plate 210. The first support plate 211 and the second support plate 212 are respectively connected to the support columns, and the base plate 210, the first support plate 211, and the second support plate 212 are arranged at intervals from bottom to top.

[0046] In the above embodiment, the support component 20 is composed of multiple support columns, which serve as the vertical load-bearing main body of the overall structure. The support columns are four sheet metal columns, which are arranged in a rectangular array in space and evenly distributed in the four corner areas of the base plate 210 to form a stable four-point support layout. The base plate 210 serves as the basic load-bearing platform and is located at the bottom of the entire frame. The lower ends of the support columns are firmly fixed to the base plate 210 by welding or bolting. On the upper part of the support columns, the first support plate 211 and the second support plate 212 are installed in sequence. Both are horizontally set and are fixedly connected to each support column by screws or snaps to realize the interlayer load transfer.

[0047] The base plate 210, the first support plate 211, and the second support plate 212 are arranged sequentially from bottom to top, forming three installation planes at different heights. Sufficient vertical distance is maintained between each plate, and multiple horizontal bars are provided between adjacent support columns. These horizontal bars connect the support columns laterally, which not only enhances the structural rigidity between the support columns and prevents them from shifting laterally under stress, but also uses the base plate 210 as the installation reference plane, with the support columns standing vertically on it. The first support plate 211 and the second support plate 212 are fixed upwards along the support columns in layers, forming a stable three-dimensional frame system composed of the base plate 210, multiple support columns, the first support plate 211, the second support plate 212, and the horizontal bars, which significantly improves the structural stability and deformation resistance of the frame.

[0048] Reference Figure 1 , Figure 4 In one embodiment, the accommodating space includes a first accommodating chamber, a second accommodating chamber, and a third accommodating chamber. The first accommodating chamber is formed by the base plate 210, the first support plate 211, and the support column. The second accommodating chamber is formed by the first support plate 211, the second support plate 212, and the support column. The third accommodating chamber is located on the side of the second support plate 212 away from the second accommodating chamber.

[0049] In the above embodiments, the accommodating space includes a first accommodating chamber, a second accommodating chamber, and a third accommodating chamber. The first accommodating chamber is located at the bottom layer of the structure and is formed by the bottom plate 210, the first support plate 211, and the support column connecting the two. The second accommodating chamber is located in the middle layer and is formed by the first support plate 211, the second support plate 212, and the support column passing through them. It is adjacent to the first accommodating chamber in the vertical direction, and the two are physically separated by the first support plate 211. The third accommodating chamber is located at the top layer and is located on the side of the second support plate 212 away from the second accommodating chamber. It is formed by the second support plate 212, the support column, and the top plate 14 and is located at the top of the overall structure.

[0050] The three compartments are arranged sequentially from bottom to top, with their central axes aligned, forming a hierarchical structure aligned vertically. The first and second compartments are the same size, while the third compartment is smaller than the first compartment. When the fuselage assembly is not installed, the first and second compartments are open structures, that is, they are surrounded by support columns and plates but open on the sides. The third compartment is open at the top and on all four sides. The entire spatial layout is connected by the bottom plate 210, the first support plate 211, the second support plate 212, the support columns, and the top plate 14, which ensures structural stability and improves the utilization of internal space.

[0051] Reference Figure 1 , Figure 4 In one embodiment, the electrical component assembly includes a first component 30, a resistor box assembly 31, and a second component 32. The first component 30 is located in the first receiving chamber and is fixedly connected to the base plate 210 and / or the support column. The resistor box assembly 31 is located in the second receiving chamber and is fixedly connected to the first support plate 211 and the support column. The second component 32 is located in the third receiving chamber and is fixedly connected to the second support plate 212. The second support plate 212 is connected to the resistor box assembly 31.

[0052] In the above embodiment, the electrical component assembly includes a first component 30, a resistor box assembly 31, and a second component 32. The first component 30 is disposed in the first receiving chamber and is a high-power, high-current electrical module, including an ACDC power module 301, a DCDC power module 302, and a relay copper busbar assembly 303. Such components are usually large in size and have thick cables, belonging to the power electrical part, and are therefore centrally arranged on the bottom layer for easy wiring close to the external power input interface. It is installed by fixing it to the base plate 210 and / or support column using bolts or clips. During installation, a certain vertical gap is maintained between the top of the first component 30 and the first support plate 211 to form a heat dissipation and operation gap, and also to provide operating space for wiring and maintenance.

[0053] The resistor box assembly 31 is located in the second housing chamber and is fixed to the first support plate 211 and the support column. Its position is close to the first component 30, which facilitates power connection via thick wires. The second support plate 212 serves as the load-bearing foundation of the upper structure. It is used not only to install the second component 32 but also to achieve structural connection with the resistor box assembly 31. The second component 32 is located in the third housing chamber. It consists of fine-wire components such as MCUs (microcontroller units), which are control signal modules. They are small in size and have dense cables. The second component 32 is directly fixed to the second support plate 212, away from the high-current area at the bottom, which effectively reduces strong electrical interference and ensures the stability of the control signal. The entire electrical component assembly is arranged in layers, forming a reasonable layout of "power at the bottom, control at the top, and heat generation in the middle". The connection relationship between each component is clear, and the space is used efficiently.

[0054] Reference Figure 1 , Figure 4 In one embodiment, the resistor box assembly 31 includes a resistor box body 310 and a resistance wire 311. The resistor box body 310 has an open structure at both ends and is located in the second accommodating chamber. The resistance wire 311 is disposed in the resistor box body 310 and is electrically connected to the first component 30 and the second component 32 respectively.

[0055] In the above embodiment, the resistor box assembly 31 includes a resistor box body 310 and a resistance wire 311. The resistor box body 310 is located in the second receiving chamber and adopts a hollow structure design with openings at both ends, that is, its left and right sides are completely open, forming a through channel. The top of the resistor box body 310 is connected to the second support plate 212 by bolts, and the bottom is connected to the first support plate 211. At the same time, it is bolted to four support columns at the four diagonal positions to form a hexahedral stable support structure. This installation method makes the second receiving chamber present an open structure with openings at both ends. The resistance wire 311 is set inside the resistor box body 310, and its two ends are electrically connected to the first component 30 and the second component 32, respectively, forming a complete electrical path. Specifically, the resistance wire 311 extends downward from the third receiving chamber, protrudes from the top plate 14, and then vertically penetrates downward into the first receiving chamber, where it is vertically wired to high-current components such as relays in the first component 30. This vertical wiring method avoids the problems of wire crossing and tangling caused by traditional horizontal wiring, making the wiring path clear, neat and orderly. The resistor box body 310 with openings at both ends allows hot air to be quickly discharged, preventing local overheating.

[0056] Reference Figure 1 , Figure 4In one embodiment, the support frame assembly 2 further includes a plurality of movable components 23, each movable component 23 including a movable bracket 230 and a roller 231.

The moving bracket 230, as a connecting structural member, is located on the side of the base plate 210 away from the support column, i.e., on the bottom plane of the base plate 210, at the lowest point of the entire frame. The moving bracket 230 is fixed to the bottom of the base plate 210 by bolts or welding, or by a detachable movable connection. The rollers 231 are movably connected to the moving bracket 230, typically using a rotating shaft or snap ring structure to achieve a rotational connection, allowing the rollers 231 to rotate freely. Multiple moving components 23 are symmetrically arranged along the edge of the base plate 210, preferably in the four corner areas of the base plate 210. When the equipment reaches the designated position, it can be stably stopped by adjusting the braking device of the rollers 231 or by using the support feet. Through the flexible rotation of the rollers 231, the entire frame structure can achieve translation and turning in any direction within workshops, laboratories, and other locations, greatly improving the deployment flexibility and ease of use of the equipment.

The top plate 14 and the second support plate 212 maintain a certain vertical distance. This gap provides the necessary internal space for the third accommodating chamber, ensuring that the top of the second component 32 installed on the second support plate 212 is also sufficiently far from the top plate 14 during operation, avoiding poor heat dissipation or assembly interference due to the narrow space.

[0067] This structural design allows the third housing chamber to be formed by the second support plate 212, top plate 14, left side plate 12, right side plate 13, front shell body 101, and rear shell body 110. Heat dissipation windows are provided on the left side plate 12 and right side plate 13 to promote air circulation inside the equipment and achieve passive heat dissipation. In particular, a cooling fan is also installed in the heat dissipation window of the right side plate 13 to actively extract hot air from the inside, enhance the heat dissipation effect, and ensure the stable operation of the equipment for a long time. The entire shell structure provides ample space for disassembly and maintenance of each housing chamber. Opening the left side plate 12, right side plate 13, or top plate 14 allows direct access to the internal components, greatly improving the convenience of maintenance.

[0068] Reference Figures 1-4 In one embodiment, the support frame assembly 2 further includes a plurality of handle assemblies 24. Each handle assembly 24 includes a handle support crossbar 240 and a handle body 241. The handle support crossbar 240 is located at the end of the support column away from the base plate 210 and is fixedly connected to an adjacent support column. The handle body 241 is fixedly connected to the handle support crossbar 240. The left side plate 12 and the right side plate 13 are respectively provided with a plurality of through holes 242 for the handle body 241 to pass through.

[0069] In the above embodiment, the support frame assembly 2 also includes multiple handle assemblies 24 for convenient handling and hoisting of the equipment. Each handle assembly 24 consists of a handle support crossbar 240 and a handle body 241. The handle support crossbar 240 is located at the end of the support column away from the base plate 210, i.e., at the top area of ​​the support column, and is horizontally fixedly connected between two adjacent support columns to form a transverse reinforcement structure. The handle body 241 is fixedly connected to the handle support crossbar 240, typically using welding or bolting to extend vertically or obliquely upwards, forming an operating area for hand gripping or sling passage. Multiple through holes 242 are provided on the left side plate 12 and right side plate 13 corresponding to the positions of the handle body 241. The size and position of these through holes 242 precisely match the handle body 241, allowing the handle body 241 to pass through. Multiple handle assemblies 24 are symmetrically arranged along the top of the support columns, typically one set on each of the front and rear sides, ensuring balanced force during handling, facilitating manual lifting or mechanical hoisting, and providing convenient operation.
