[0012] In some embodiments, both ends of the plate extend along a second direction to the outer side of the first flange, and the chassis further includes a plurality of connectors, which are respectively disposed at both ends of the plate, and the plate is connected to the chassis through the connectors;

[0013] Alternatively, a plurality of the connectors are arranged at intervals along the second direction on the plate, and at least some of the connectors are disposed at both ends of the plate. The main body is provided with through holes, and each connector located between the first flanges corresponds to one of the through holes.

[0014] In some embodiments, the fixing plate further includes a positioning part connected to one end of the plate body, wherein when the reinforcing rib abuts against the positioning part, the movement of the reinforcing rib toward the positioning part is restricted.

[0015] In some embodiments, the plate includes a main body, two bending portions and two flat pressing portions. The main body is connected to one bending portion on each side along the first direction, and each bending portion is connected to a flat pressing portion on the side away from the main body.

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "height," "thickness," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In the description of this application, "a plurality of" means two or more, and "at least one" can mean one, two, or more, unless otherwise expressly specified.

[0037] It should also be noted that in the accompanying drawings of the embodiments of this application, the arrow marked X represents the first direction X, the arrow marked Y represents the second direction Y, and the arrow marked Z represents the third direction Z. The first direction X, the second direction Y, and the third direction Z are introduced to more clearly illustrate the structure and relative positional relationship of the components in the chassis. In practical applications, the first direction X, the second direction Y, and the third direction Z may change depending on the placement of the chassis. In the description of this application, "perpendicular" means completely perpendicular to 90° or almost completely perpendicular. For example, an angle of 85° to 95° is considered perpendicular. Similarly, "parallel" means completely parallel or almost completely parallel. For example, a completely parallel angle of 10° is considered parallel.

[0038] As a prelude to the embodiments of this application, some of the enclosures of the energy storage device are heavy components, and the enclosure itself cannot meet the load-bearing requirements. Therefore, it is necessary to weld reinforcing ribs to the main load-bearing parts of the enclosure to support the weight of the components inside the enclosure.

[0039] Due to various processing factors, the surface of the welded areas of the chassis may have defects such as depressions, protrusions, or undulations, resulting in uneven flatness distribution. In order to even out stress distribution, existing reinforcing ribs are typically welded with their larger surfaces close to the chassis. This increases the coverage area of ​​the reinforcing ribs on the chassis, increasing the likelihood of them contacting areas with uneven flatness distribution. It also makes it more difficult to avoid these areas by adjusting the relative position of the reinforcing ribs to the chassis. Furthermore, a large contact area between the reinforcing ribs and the chassis means that the cumulative processing errors in the corresponding contact areas may also be significant. Therefore, the fit between conventional reinforcing ribs and the chassis is difficult to control, and welding defects such as porosity or slag inclusions are prone to occur, affecting the welding quality.

[0040] Please combine them together Figure 1 , Figure 2 and Figure 3 The chassis of this application embodiment includes a housing 1 and a reinforcing rib 2. The housing 1 includes a bearing surface 11, which is a surface of the chassis used to bear the main load of its internal components, and the surface is perpendicular to the direction of the load force. The reinforcing rib 2 includes a body portion 20 and a plurality of first flanges 21. The plurality of first flanges 21 are connected to the body portion 20, and at least a portion of each first flange 21 is attached to and welded to the bearing surface 11.

[0041] The first flange 21 is integrally formed with the main body 20 and is formed by bending a sheet metal. The width of the first flange 21 attached to the bearing surface 11 is smaller than the width of the main body 20. Therefore, its contact area with the chassis is correspondingly reduced, which can more easily avoid the uneven flatness of the bearing surface 11 or reduce the contact area with the uneven flatness of the bearing surface 11. This allows the first flange 21 to fully fit the bearing surface 11, thereby reducing the gap between them, reducing the possibility of welding defects, and thus achieving the purpose of improving welding quality.

[0042] In this embodiment, the chassis is made of aluminum. To facilitate welding to the chassis, the reinforcing rib 2 is also made of aluminum. To ensure the strength and rigidity of the aluminum reinforcing rib 2, the first flange 21 is formed by bending. This, combined with the main body 20, increases the thickness and area of ​​the reinforcing rib 2's cross-section, thereby improving its bending stiffness and strength, and ultimately enhancing the chassis's load-bearing capacity and resistance to deformation. In other embodiments, the chassis may also be made of stainless steel, magnesium alloy, etc.

[0043] Please combine them together Figure 2 and Figure 3, in some embodiments, a first flanging 21 is provided on each of the two sides of the body portion 20 along the first direction X, and the two first flangings 21 are arranged at intervals. The first flanging 21 extends along the second direction Y, and the first direction X intersects the second direction Y. That is to say, the first direction X and the second direction Y are distributed at an angle in the same plane, and the angle is 85°-95°, preferably 90°. In this embodiment, the first direction X is the width direction of the body portion 20, and the second direction Y is the length direction of the body portion 20. In some other embodiments, the first direction X can also be the length direction of the body portion 20, and then the second direction Y is the width direction of the body portion 20, as long as it is ensured that the two first flangings 21 are arranged oppositely.

[0044] The first flangings 21 are arranged oppositely. On the one hand, it can make the overall force of the reinforcing rib 2 uniform, and on the other hand, it can avoid the uneven positions of the chassis through the distance between the two first flangings 21.

[0045] In some other embodiments, a plurality of first flangings 21 are provided on each of the two sides of the body portion 20 along the first direction X, the first flangings 21 on both sides are arranged at intervals, and the plurality of first flangings 21 on each side are arranged in sequence along the second direction Y.

[0046] Please refer to Figure 4 , in some embodiments, in the first direction X, the width of the part of the first flanging 21 adhering to the bearing surface 11 is D mm, the width of the body portion 20 is L1 mm, and the thickness of the body portion 20 is L2 mm, satisfying: L2 < D ≤ L1 / 15. By limiting the size of the first flanging 21, the first flanging 21 can meet the requirements of both the welding surface and its own strength.

[0047] Please refer to Figure 4 , in some embodiments, the first flanging 21 is L-shaped, including a first section 211 and a second section 212. The first section 211 is connected to the body portion 20 and extends along the thickness direction of the body portion 20. The second section 212 is connected to the side of the first section 211 far from the body portion 20 and is parallel to the body portion 20. The second section 212 adheres to the bearing surface 11 and is welded to the bearing surface 11.

[0048] The positive projection of the second section 212 and the body portion 20 on the bearing surface 11 along the third direction Z coincides. The third direction Z intersects the first direction X and the second direction Y at the same time, which is the thickness direction of the body portion 20. The second section 212 is folded inwards, which can save the occupation of the outer space of the first section 211, hide the edges of the reinforcing rib 2, and maintain the flatness of the outer surface of the reinforcing rib 2.

[0049] In some other embodiments, the two first flanges 21 may also be configured to extend relative to each other along the first direction X, that is, the first flanges 21 are formed by bending the sheet once and are parallel to the body part 20. In this case, the first flanges 21 are all attached to the bearing surface 11.

[0050] Please combine them together Figure 5 , Figure 6 and Figure 7 In some embodiments, the chassis further includes a fixing plate 3, which includes a plate body 31. At least a portion of the plate body 31 is disposed on the side of the second segment 212 away from the chassis 1 and abuts against the first flange 21. The plate body 31 is connected to the chassis 1 to press the plurality of second segments 212 against the bearing surface 11. Under the pressure of the plate body 31, the second segments 212 adhere to the bearing surface 11, thereby improving the tightness between them and limiting the deformation of the first flange 21 during welding, which helps to improve the welding quality between the first flange 21 and the chassis 1. After welding, the fixing plate 3 can be removed or left on the chassis 1 together with the reinforcing rib 2, which can stabilize the connection of the reinforcing rib 2 and increase the strength of the chassis 1.

[0051] In this embodiment, there is one fixing plate 3, that is, each first flange 21 is pressed by one plate 31. In other embodiments, the number of fixing plates 3 can also be the same as the number of first flanges 21, that is, each first flange 21 corresponds to one plate 31 and is pressed separately. Correspondingly, each plate 31 is individually connected to the box 1.

[0052] Please combine them together Figure 5 , Figure 6 and Figure 7 In some embodiments, both ends of the plate 31 extend along the second direction Y to the outside of the first flange 21, that is, the length of the plate 31 is greater than the length of the first flange 21. At the same time, in order to avoid the plate 31 occupying the space around the box 1, when the reinforcing rib 2 is arranged parallel to the width of the box 1, the maximum length of the plate 31 is not greater than the width of the box 1, and when the reinforcing rib 2 is arranged parallel to the length of the box 1, the maximum length of the plate 31 is not greater than the length of the box 1.

[0053] The chassis also includes multiple connectors 4, which are respectively located at both ends of the plate 31. The plate 31 is connected to the housing 1 via the connectors 4. The plate 31 is detachably connected to the housing 1 via the connectors 4. After the reinforcing ribs 2 are welded, the plate 31 can be removed and pulled out. At the same time, since the connectors 4 are all located on the outside of the first flange 21, there is ample operating space, which facilitates the assembly and disassembly of the plate 31.

[0054] Alternatively, multiple connectors 4 are arranged at intervals along the second direction Y on the plate 31, with at least some of the connectors 4 located at both ends of the plate 31. The main body 20 is provided with through holes 201 extending along its thickness direction, and each connector 4 located between the first flanges 21 corresponds to a through hole 201. The spaced connectors 4 ensure that the plate 31 is subjected to uniform force, which increases the number of points of force applied to the first flanges 21, allowing the first flanges 21 to better fit the bearing surface 11. The through holes 201 also facilitate the assembly and disassembly of the connectors 4 located inside the first flanges 21.

[0055] In this embodiment, the connector 4 can be a screw, a press-fit screw, a press-fit nut, or other similar structure.

[0056] Please combine them together Figure 5 and Figure 6 In some embodiments, the fixing plate 3 further includes a positioning part 32, which is connected to one end of the plate body 31. When the reinforcing rib 2 abuts against the positioning part 32, the movement of the reinforcing rib 2 toward the positioning part 32 is restricted.

[0057] In this embodiment, there are two positioning parts 32, and the two positioning parts 32 are connected to the two sides of the plate 31 along the first direction X. In the first direction X, the distance between the two opposite sides of the two positioning parts 32 is greater than the distance between the two first flanges 21. So when the positioning part 32 abuts against the first flange 21, it restricts the relative position of the reinforcing rib 2 and the plate 31, thereby making each reinforcing rib 2 arranged in the same direction and improving the uniformity of the load-bearing capacity of the reinforcing rib 2.

[0058] In some other embodiments, the positioning part 32 may also be vertically connected to the side of the plate 31 away from the bearing surface 11. In the third direction Z, the combined size of the positioning part 32 and the plate 31 is larger than the distance between the main body 20 and the second segment 212. The relative position between the reinforcing rib 2 and the plate 31 is limited by the contact between the positioning part 32 and the main body 20.

[0059] Please combine them together Figure 5 and Figure 7 In some embodiments, the plate 31 includes a main body 311, two bent portions 312, and two flat pressing portions 313. One bent portion 312 is connected to each side of the main body 311 along the first direction X. A flat pressing portion 313 is connected to the side of each bent portion 312 away from the main body 311. The flat pressing portions 313 and the main body 311 are staggered along the third direction Z. That is, when the main body 311 is attached to the bearing surface 11, there is a gap between the flat pressing portions 313 and the bearing surface 11. The main body 311, the two bent portions 312, and the two flat pressing portions 313 can be an integrally formed structure, created by bending a sheet metal. Both sides of the bent portions 312 adopt an arc-shaped transition to reduce stress concentration.

[0060] The main body 311 is disposed between the two second sections 212 and connected to the housing 1. Each flat pressing part 313 corresponds to one second section 212 and is disposed on the side of the second section 212 away from the bearing surface 11. The plate 31 increases its own strength by bending, reducing the possibility of deformation when the second section 212 is pressed.

[0061] When the connector 4 and the positioning part 32 are combined, the connector 4 is provided on the main body 311, and the positioning part 32 is provided on the side of the flat pressing part 313 away from the main body 311.

[0062] Please refer to Figure 9 In some embodiments, in the first direction X, the portion of the first flange 21 that is attached to the bearing surface 11 extends in a direction away from the body portion 20. Specifically, the second segment 212 of the first flange 21 extends in a direction away from the body portion 20. At this time, the first flange 21 is folded outward, which can provide the operator with relatively ample space during welding and facilitate observation of the weld.

[0063] Please refer to Figure 9 In some embodiments, the chassis further includes multiple fixing plates 3, with each first flange 21 corresponding to one fixing plate 3. The fixing plate 3 is located on the side of the first flange 21 facing away from the chassis 1 and is connected to the chassis 1. Since the second segment 212 of the first flange 21 is located outside the first segment 211, it has a relatively large operating space, making the connection between the fixing plate 3 and the chassis 1 relatively convenient. The connection between the fixing plate 3 and the chassis 1 can be achieved using screws, rivet screws, rivet nuts, etc. Correspondingly, process holes can be pre-set on the fixing plate 3 and the first flange 21 for mating connection.

[0064] In some embodiments, the second segment 212 of the first flange 21 can also be a separate structure from the first segment 211. In this case, the first segment 211 and the second segment 212 form a T-shape, that is, part of the second segment 212 extends inward and part extends outward to meet the design requirements under different working conditions.

[0065] Please refer to Figure 2 In some embodiments, the reinforcing rib 2 further includes a plurality of second flanges 22, which are respectively connected to both ends of the body portion 20 along the second direction Y. The second flanges 22 are perpendicular to the body portion 20 and can be integrally formed. The second flanges 22 can work with the first flanges 21 to further enhance the overall strength of the reinforcing rib 2. At the same time, the second flanges 22 are also symmetrical structures, which helps to distribute stress evenly.

[0066] Please combine them together Figure 4 and Figure 5In some embodiments, there is a gap between the portions of the second flange 22 and the first flange 21 that are attached to the bearing surface 11. The gap separates the portions of the second flange 22 and the first flange 21 that are attached to the bearing surface 11, providing operating space for the flange bending process and preventing mutual interference.

[0067] Since there is a gap between the second flange 22 and the first flange 21 that are attached to the bearing surface 11, the fixing plate 3 is slidably inserted between the two first flanges 21, and specifically between the second flange 22 and the second section 212 of the first flange 21, providing clearance space for the movement of the plate 31.

[0068] Please combine them together Figure 1 and Figure 8 In some embodiments, the housing 1 has a receiving cavity 12, and a bearing surface 11 is disposed in the receiving cavity 12 and is directly opposite to the opening of the receiving cavity 12 in the third direction Z. In this case, the bearing surface 11 is the inner bottom surface of the housing 1.

[0069] Alternatively, the bearing surface 11 can be located on the outside of the housing 1, facing away from the opening of the receiving cavity 12 in the third direction Z. In this case, the bearing surface 11 is the outer bottom surface of the housing 1. The reinforcing rib 2 can be installed inside or outside the housing 1 depending on different working conditions. When the reinforcing rib 2 is fixed inside the housing 1, it can both reinforce the bottom of the housing 1 and protect the reinforcing rib 2. When the reinforcing rib 2 is fixed outside the housing 1, it can avoid occupying the internal space of the housing 1.

[0070] In some embodiments, the reinforcing rib 2 is provided with a corrosion-resistant layer, which is generated on the surface of the reinforcing rib 2 using ALD (Atomic Layer Deposition) technology, which can extend the service life of the reinforcing rib 2 and increase the chassis's adaptability to different operating environments.

[0071] In some embodiments, the fixing plate 3 can be made of stainless steel plate. Since stainless steel plate has high strength, when connecting fixing plate 3 and box 1, it can maintain its shape when pressure is applied to the first flange 21, and there is no need to bend it to increase strength, which is convenient to use.

[0072] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0073] The chassis provided in the embodiments of this application has been described in detail above, and specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
