[0001] This utility model relates generally to the technical field of container structures, and more specifically to a container bottom structure and a container. Background Technology

[0002] The energy storage containers in related technologies have insufficient bottom structural strength, making them difficult to apply in situations with higher load-bearing requirements.

[0003] Therefore, there is a need to provide a container bottom structure and a container to at least partially solve the above problems. Utility Model Content

[0004] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the first aspect of this utility model provides a box bottom structure, the box bottom structure having a battery carrying area and an electrical carrying area, the battery carrying area and the electrical carrying area being arranged along the length direction of the box bottom structure, the battery carrying area being adapted to house energy storage batteries, and the electrical carrying area being adapted to house at least electrical control equipment, the box bottom structure comprising:

[0006] A bottom longitudinal beam, which extends along the length direction;

[0007] A pair of bottom side beams, the pair of bottom side beams being located on both sides of the bottom longitudinal beam along the width direction of the box bottom structure;

[0008] Two sets of bottom crossbeams, located on either side of the bottom longitudinal beam along the width direction, with each end of the bottom crossbeam connected to the bottom longitudinal beam and the bottom side beam, respectively. Each set of bottom crossbeams includes multiple bottom crossbeams, which are spaced apart along the length direction; and

[0009] Two sets of first floor panels are located in the battery-bearing area. The two sets of first floor panels are located on both sides of the bottom longitudinal beam along the width direction.

[0010] According to the bottom structure of the first aspect of this utility model, by setting the first floor located in the battery bearing area such that "the end of the first floor near the bottom longitudinal beam is higher than the end of the first floor near the bottom side beam," liquid can be guided towards the direction near the bottom side beam. This prevents liquid from accumulating in the middle of the bottom structure along its width, and allows for the collection of liquid using receiving tanks and the isolation of liquid in each receiving tank by the bottom crossbeams, preventing liquid from flowing randomly. This makes the liquid distribution controllable. Moreover, by providing a bending section in the first floor, the bending resistance of the first floor can be enhanced.

[0020] A floor drain assembly, wherein the floor drain assembly is disposed at one end of the first floor near the bottom side beam; and

[0021] A connecting pipe, at least a portion of which is embedded in the bottom crossbeam, the connecting pipe extending along the length direction, the connecting pipe being arranged corresponding to one end of the first floor near the bottom side beam, and the connecting pipe connecting to the adjacent receiving groove.

[0058] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0059] This utility model provides a container bottom structure 100 and a container having the container bottom structure 100. See below. Figures 1 to 7 The container bottom structure 100 and the container having the container bottom structure 100 according to embodiments of this application will be described in detail.

[0060] See Figures 1 to 4According to an embodiment of the present invention, the bottom structure 100 has a battery carrying area 101 and an electrical carrying area 102. The battery carrying area 101 and the electrical carrying area 102 are arranged along the length direction D1 of the bottom structure 100. The battery carrying area 101 is suitable for arranging energy storage batteries. The electrical carrying area 102 is suitable for arranging at least electrical control equipment. The bottom structure 100 includes a bottom longitudinal beam 103, a pair of bottom side beams 104, two sets of bottom cross beams 105, and two sets of first floor panels 106. The bottom longitudinal beam 103 extends along the length direction D1. The pair of bottom side beams 104 are located on both sides of the bottom longitudinal beam 103 along the width direction D2 of the bottom structure 100. The bottom side beams 104 are parallel to the bottom longitudinal beam 103. The two sets of bottom cross beams 105 are located on both sides of the bottom longitudinal beam 103 along the width direction D2. The bottom cross beams 105 extend along the width direction D2. The two ends of the bottom crossbeam 105 are connected to the bottom longitudinal beam 103 and the bottom side beam 104, respectively. Each set of bottom crossbeams 105 includes multiple bottom crossbeams 105. The multiple bottom crossbeams 105 are arranged at intervals along the length direction D1. Two sets of first floor panels 106 are located in the battery support area 101. The two sets of first floor panels 106 are located on both sides of the bottom longitudinal beam 103 along the width direction D2. Each set of first floor panels 106 includes multiple first floor panels 106. The two ends of the first floor panels 106 along the width direction D2 are connected to the bottom longitudinal beam 103 and the bottom side beam 104, respectively. The end of the first floor panel 106 along the width direction D2 is connected to the bottom crossbeam 105. In the height direction D3 of the box bottom structure 100, the end of the first floor panel 106 near the bottom longitudinal beam 103 is higher than the end of the first floor panel 106 near the bottom side beam 104. The first floor panel 106 includes a bent portion 106c. Furthermore, the first floor 106 is lower than the top surface of the bottom crossbeam 105 and the top surface of the bottom longitudinal beam 103. The first floor 106, the bottom longitudinal beam 103, the bottom crossbeam 105, and the bottom side beam 104 enclose and form a receiving groove 107.

[0061] According to an embodiment of the present invention, the bottom structure 100 of the box can guides liquid flow towards the bottom side beam 104 by setting the first floor 106 located in the battery bearing area 101 such that "the end of the first floor 106 near the bottom longitudinal beam 103 is higher than the end of the first floor 106 near the bottom side beam 104". This prevents liquid from accumulating in the middle of the bottom structure 100 along the width direction D2, and allows the collection of liquid using the receiving grooves 107 and the isolation of liquid in each receiving groove 107 by the bottom cross beam 105 to prevent liquid from flowing randomly. This makes the distribution range of liquid in the upper part of the bottom structure 100 controllable, reducing the risk of water accumulation. Moreover, by providing a bending portion 106c in the first floor 106, the bending resistance of the first floor 106 can be enhanced. Compared with a flat floor, this is beneficial to improving the overall strength of the bottom structure 100, thereby helping to improve the load-bearing capacity of the bottom structure 100 and thus adapting to the application requirements of greater load weight. When the bottom structure 100 is applied to a container, the total weight of goods or equipment that the container can carry can be increased.

[0062] See Figure 3 and Figure 5 In some embodiments, the first floor 106 includes a first plate 106a and a second plate 106b connected sequentially along the width direction D2. The first plate 106a and the second plate 106b are arranged intersectingly. The end of the first plate 106a away from the second plate 106b is connected to the bottom longitudinal beam 103. The end of the second plate 106b away from the first plate 106a is connected to the bottom side beam 104. A bend 106c is formed at the connection between the first plate 106a and the second plate 106b. When liquid drips onto the first plate 106a, the liquid flows from the first plate 106a to the second plate 106b until it reaches the lowest point of the second plate 106b. When liquid drips onto the second plate 106b, the liquid flows from the point where it drips onto the second plate 106b to the lowest point of the second plate 106b until it reaches the lowest point of the second plate 106b. By configuring the first floor 106 to have intersecting first plate 106a and second plate 106b, the overall outline of the first floor 106 is V-shaped or other shapes similar to V-shaped, thereby improving the structural strength of the first floor 106 while simplifying its structure, and thus facilitating the processing and manufacturing of the first floor 106.

[0063] See Figure 5Schematably, a first included angle α1 is formed between the first plate 106a and the second plate 106b. The first included angle α1 is located on the upper side of the first plate 106. The first included angle α1 is greater than 0° and less than 180°. Preferably, the first included angle α1 is an obtuse angle. It can be understood that the first plate 106a is bent upward relative to the second plate 106b. The bent portion 106c is formed at the part of the first plate 106a that is bent relative to the second plate 106b.

[0064] In the illustrated example, the first plate 106a is inclined in the height direction D3. The second plate 106b is perpendicular to the height direction D3. That is, the first plate 106a is an inclined plate, and the second plate 106b is a horizontally arranged plate. When the first floor 106 is a metal plate such as stainless steel, the first floor 106 is constructed by stamping the metal plate with a punch or bending it with a bending machine.

[0065] Furthermore, in the width direction D2, the size of the first plate 106a is larger than the size of the second plate 106b. When the amount of liquid is small, the liquid can be confined to the area corresponding to the second plate 106b, thereby reducing the distribution range of the liquid on the first plate 106, thus reducing the impact of the liquid on energy storage batteries, etc., and also helping to improve the liquid discharge efficiency.

[0066] See Figure 6 Schematic illustration: The first floor 206 includes a first plate 206a and a second plate 206b. A second included angle α2 is formed between the first plate 206a and the second plate 206b. The second included angle α2 is located on the lower side of the first floor 206. The second included angle α2 is greater than 0° and less than 180°. Preferably, the second included angle α2 is an obtuse angle. It can be understood that the second plate 206b is bent downward relative to the first plate 206a. The bent portion 206c is formed at the location where the first plate 206a is bent relative to the second plate 206b.

[0067] exist Figure 6 In the example shown, the first plate 206a is inclined in the height direction D3. The second plate 206b is also inclined in the height direction D3. The absolute value of the slope of the first plate 206a is less than the absolute value of the slope of the second plate 206b. That is, the inclination of the first plate 206a is less than the inclination of the second plate 206b. When the first floor 206 is a metal plate such as stainless steel, the first floor 206 is constructed by stamping the metal plate with a punch or bending it with a bending machine.

[0068] In other embodiments, the first floor includes at least two bends. The bends are spaced apart along the width direction D2. Compared to having only one bend, having at least two bends further improves the bending resistance of the first floor, thereby increasing its structural strength and contributing to further improving the structural strength and load-bearing capacity of the box bottom structure 100.

[0069] See Figure 7 Furthermore, the first floor 306 includes two bent portions 306c. The first floor 306 includes a first plate 306a, a second plate 306b, and a third plate 306d arranged sequentially along the width direction D2. The first plate 306a and the second plate 306b are arranged intersectingly. The second plate 306b and the third plate 306d are arranged intersectingly. One end of the first plate 306a away from the second plate 306b is connected to the bottom longitudinal beam 103. The end of the third plate 306d away from the second plate 306b is connected to the bottom side beam 104. One of the two bent portions 306c is formed at the connection between the first plate 306a and the second plate 306b. The other of the two bent portions 306c is formed at the connection between the second plate 306b and the third plate 306d. When liquid drips onto the first plate 306a, it flows from the first plate 306a to the third plate 306d until it reaches the lowest point of the third plate 306d. When liquid drips onto the second plate 306b, it flows from the second plate 306b to the third plate 306d until it reaches the lowest point of the third plate 306d. When liquid drips onto the third plate 306d, it flows from the point where it drips onto the third plate 306d to the lowest point of the third plate 306d until it reaches the lowest point of the third plate 306d.

[0070] Continue reading Figure 7 Furthermore, a third included angle α3 is formed between the first plate 306a and the second plate 306b. The third included angle α3 is located below the first floor 306. A fourth included angle α4 is formed between the second plate 306b and the third plate 306d. The fourth included angle α4 is located above the first floor 306. It can be understood that the second plate 306b is bent downwards relative to the first plate 306a, and the second plate 306b is bent upwards relative to the third plate 306d, with the bending directions of the two bent portions 306c being opposite. The third included angle α3 is greater than 0° and less than 180°. Preferably, the third included angle α3 is an obtuse angle. The fourth included angle α4 is greater than 0° and less than 180°. Preferably, the fourth included angle α4 is an obtuse angle.

[0071] exist Figure 7In the example shown, the first plate 306a is perpendicular to the height direction D3. The second plate 306b is inclined to the height direction D3. The third plate 306d is perpendicular to the height direction D3. It can be understood that the first plate 306a is a horizontally arranged plate structure, the second plate 306b is an inclined plate structure, and the third plate 306d is a horizontally arranged plate structure.

[0072] Optionally, in the width direction D2, the size of the first plate 306a is smaller than the size of the second plate 306b, and the size of the second plate 306b is larger than the size of the third plate 306d.

[0073] See Figure 1 , Figure 2 as well as Figure 3 In addition, the bottom structure 100 also includes a drain assembly 110 and a connecting pipe 120. The drain assembly 110 is disposed at one end of the first floor 106 near the bottom side beam 104. At least a portion of the connecting pipe 120 is embedded in the bottom cross beam 105. The connecting pipe 120 extends along the length direction D1. The connecting pipe 120 is arranged corresponding to the end of the first floor 106 near the bottom side beam 104. The connecting pipe 120 connects to an adjacent receiving tank 107. The drain assembly 110 is used to drain liquid from the receiving tank 107 when it is open, and to retain liquid in the receiving tank 107 when it is closed. By providing the connecting pipe 120 to connect adjacent receiving tanks 107, liquid can flow through the connecting pipe 120 to the receiving tank 107 where the drain assembly 110 is provided, thus eliminating the need to provide a drain assembly 110 in each receiving tank 107. Compared to the approach of installing a drain assembly 110 in each receiving tank 107, installing a connecting pipe 120 and placing the drain assembly 110 in only a portion of the receiving tanks 107 reduces costs and simplifies the operation when draining liquid. Furthermore, since the receiving tanks 107 are interconnected via the connecting pipe 120, the liquid level in each receiving tank 107 can be kept consistent even when the drain assembly 110 is closed. This helps prevent electrical short circuits and other malfunctions caused by excessively high liquid levels in some receiving tanks 107, thereby improving electrical safety.

[0074] exist Figure 1 and Figure 2 In the example shown, the bottom structure 100 is provided with two drain assemblies 110. The two drain assemblies 110 are located on both sides of the bottom longitudinal beam 103. In the length direction D1, the drain assemblies 110 are located in the middle of the battery carrying area 101. This reduces the number of drain assemblies 110 while improving the efficiency of liquid collection in the receiving tank 107 without drain assemblies 110 to the receiving tank 107 with drain assemblies 110.

[0075] Optionally, the bottom crossbeam 105 has mounting holes. The connecting pipe 120 passes through the mounting holes and is welded to the bottom crossbeam 105.

[0076] See Figure 4 Furthermore, the drain assembly 110 includes a liquid receiving element 111, a drain pipe 112, and a plug 113. The upper part of the liquid receiving element 111 has a groove suitable for receiving liquid. The groove is flared, wider at the top and narrower at the bottom. The upper part of the drain pipe 112 is connected to the liquid receiving element 111 and communicates with the receiving tank 107 through the liquid receiving element 111. The plug 113 is detachably connected to the lower end of the drain pipe 112 by a screw connection or other detachable connection method. When the plug 113 is connected to the drain pipe 112, the drain assembly 110 is in a closed state, preventing liquid discharge. When the plug 113 is detached from the drain pipe 112, the drain assembly 110 is in an open state, allowing liquid to drain, thereby achieving the purpose of draining liquid.

[0077] See Figure 1 and Figure 2 In an embodiment of this application, the bottom longitudinal beam 103 includes a first longitudinal beam segment 103a and a second longitudinal beam segment 103b arranged sequentially along the length direction D1. The top surface of the first longitudinal beam segment 103a is higher than the top surface of the second longitudinal beam segment 103b. The first longitudinal beam segment 103a is located in the battery carrying area 101. The second longitudinal beam segment 103b is at least partially located in the electrical carrying area 102. The first floor 106 is lower than the top surface of the bottom crossbeam 105. The bottom crossbeam 105 is lower than the top surface of the first longitudinal beam segment 103a. The top surface of the bottom crossbeam 105 is flush with the top surface of the second longitudinal beam segment 103b. The box bottom structure 100 also includes a second floor 130. The second floor 130 is located in the electrical carrying area 102. The second floor 130 is connected to the upper part of the second longitudinal beam segment 103b and the upper part of the bottom crossbeam 105. By setting the top surface of the second longitudinal beam segment 103b corresponding to the electrical load-bearing area 102 to be flush with the top surface of the bottom crossbeam 105, and setting the top surface of the first longitudinal beam segment 103a corresponding to the battery load-bearing area 101 to be higher than the top surface of the bottom crossbeam 105, the structural strength and load-bearing performance of the box bottom structure 100 in the battery load-bearing area 101 can be improved. On the other hand, the height of the second floor 130 can be reduced, so that more space can be reserved for equipment such as electrical control cabinets in the height direction D3, thereby allowing the arrangement of equipment with larger height dimensions and improving the compatibility of equipment selection.

[0078] Continue reading Figure 1 and Figure 2 Optionally, a portion of the second longitudinal beam segment 103b is located in the battery bearing area 101. This portion of the second longitudinal beam segment 103b is used to avoid certain hardware structures or for wiring.

[0079] See also Figure 1 and Figure 2 Optionally, the electrical bearing area 102 is provided with two second floor panels 130. The two second floor panels 130 are distributed along the width direction D2 on both sides of the bottom longitudinal beam 103. The upper part of one second floor panel 130 is used to install liquid cooling equipment. The upper part of the other second floor panel 130 is used to install electrical control equipment. The second floor panel 130 used for accommodating the electrical control equipment has through holes 131. The through holes 131 are used for cable routing.

[0080] See Figure 1 , Figure 3 as well as Figure 4 In addition, a bottom sealing plate 140 is provided at the lower part of the box bottom structure 100. The bottom sealing plate 140 is connected to the lower part of the bottom longitudinal beam 103, the lower part of the bottom side beam 104, and the lower part of the bottom transverse beam 105. The bottom sealing plate 140 is used to close the open structure at the lower part of the box bottom structure 100 to improve the integrity, flatness, and aesthetics of the lower part of the box bottom structure 100.

[0081] An embodiment of this utility model provides a container. This container is an energy storage container. The container includes the aforementioned bottom structure 100.
