[0030] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0031] ​The embodiments of the present application are used only for explaining the present application, and are not used for limiting the scope of the present application. The present application is described in more detail with reference to the accompanying drawings in the following paragraphs. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, only for the purpose of conveniently, clearly and simply assisting in the description of the embodiments of the present application.

[0032] At present, in one way, the gas tank is arranged at the rear of the whole vehicle, such as the bottom of the trunk. In another way, the gas tank is arranged at the front of the whole vehicle, such as the front subframe cross beam. However, the weight of the gas tank is large, and additional mounting brackets, longitudinal beam reinforcements, reinforcing plates and other components are required during installation, thereby causing the weight of the whole vehicle to increase. In addition, the gas tank occupies a large space, and when the gas tank is arranged at the rear of the whole vehicle, it will occupy the layout space at the rear of the whole vehicle, affect the volume of the trunk, and also affect the layout of other rear functional modules. When the gas tank is arranged at the front of the whole vehicle, it will occupy the layout space at the front of the whole vehicle, affect the space of the front subframe, front shock absorber and other structures, and is not conducive to the structural path design of the vehicle body. If the gas tank is not used, other gas storage structures are difficult to provide sufficient pressure bearing capacity. In addition, when the gas tank is connected to the bottom of the trunk through the mounting bracket, the distance between the gas tank and the ground is small, and the risk of scraping the ground is easy to occur, which endangers the safety of driving. In addition, the gas tank and the mounting bracket need to be manufactured separately, which increases the cost of the whole vehicle. In order to solve the above problems, the embodiments of the present application provide a rocker assembly and a vehicle, which are described in detail below.

[0033] In the first aspect, with reference to Figure 1 , Figure 2 and Figure 5 , the rocker assembly provided by the embodiments of the present application comprises: a rocker beam 1 comprising at least one first structural cavity 11; and at least one cover plate assembly connected to the rocker beam 1, the cover plate assembly comprising two cover plates 2, the two cover plates 2 being respectively located at two ends of the first structural cavity 11, and the two cover plates 2 and the first structural cavity 11 surrounding a gas storage cavity 3, the gas storage cavity 3 being used for storing gas, wherein the rocker beam 1 further comprises at least one second structural cavity 12, a first plate body 14 and a second plate body 15, the first structural cavity 11 being surrounded by the at least one first plate body 14, and the second plate body 15 being used for surrounding the second structural cavity 12, and the thickness of the first plate body 14 being greater than the thickness of the second plate body 15.

[0034] Specifically, the material of the rocker beam 1 can be aluminum, and the rocker beam 1 can be integrally extruded. A plurality of connecting plates are fixed on the rocker beam 1, and the connecting plates are used for being connected to the vehicle body. The connection mode of the rocker beam 1 and the connecting plate can be bolt connection, screw connection, riveting or welding. The connection mode of the connecting plate and the vehicle body can be bolt connection, screw connection or welding.

[0035] The first structural cavity 11 preferably penetrates the rocker beam 1 along the length direction of the rocker beam 1. The number of the first structural cavities 11 can be determined according to the gas storage volume, for example, the number of the first structural cavities 11 is one or two. The rocker beam 1 has multiple cavities, and the number of the first structural cavities 11 is preferably one, and the first structural cavity 11 is preferably one with the largest cross-sectional area among the multiple cavities of the rocker beam 1, so that the gas storage cavity 3 has sufficient volume.

[0036] The second structural cavity 12 preferably penetrates the rocker beam 1 along the length direction of the rocker beam 1. The number of the second structural cavities 12 can be set according to actual needs, for example, the number of the second structural cavities 12 is two to seven. The second structural cavity 12 is specifically a cavity of the rocker beam 1 other than the first structural cavity 11.

[0037] The number of the cover plate assemblies is equal to the number of the first structural cavities 11, and the two cover plates 2 in one cover plate assembly and one first structural cavity 11 form one closed gas storage cavity 3. The cross-sectional area of the cover plate 2 is greater than the cross-sectional area of the first structural cavity 11, the cross-section of the cover plate 2 is the cross-section of the cover plate 2 perpendicular to the length direction of the rocker beam 1, the cross-section of the first structural cavity 11 is the cross-section of the first structural cavity 11 perpendicular to the length direction of the rocker beam 1, and the cover plate 2 cooperates with the first structural cavity 11 to ensure the sealing of the gas storage cavity 3.

[0038] The material of the cover plate 2 can be aluminum, steel, etc. The gas storage cavity 3 is specifically used for supplying air to the air spring in the vehicle. The cover plate 2 can be provided with a gas pipe joint, the gas pipe joint is in communication with the gas storage cavity 3, and the gas pipe joint is used to be connected with a connecting pipeline, the connecting pipeline is connected with the air spring. When the number of the gas storage cavities 3 is multiple, the gas pipe joints corresponding to the multiple gas storage cavities 3 are in communication.

[0039] The first plate body 14 is used to form the first structural cavity 11. The cross-sectional shape of the first structural cavity 11 can be rectangular, circular, etc. When the cross-sectional shape of the first structural cavity 11 is rectangular, the first structural cavity 11 is formed by four first plate bodies 14. It should be noted that the first plate body 14 is connected with the cover plate 2, and is not connected with other external structures. The first structural cavity 11 has two openings arranged opposite along the length direction of the rocker beam 1, and has no other openings.

[0040] The second structural cavity 12 can be surrounded by a plurality of second plate bodies 15, and the second structural cavity 12 can also be surrounded by a plurality of second plate bodies 15 and a first plate body 14. The difference between the thickness of the first plate body 14 and the thickness of the second plate body 15 is preferably greater than 1 mm. In this application, the thickness of the first plate body 14 is increased, so that the thickness of the first plate body 14 is greater than the thickness of the second plate body 15. The first plate body 14 with greater thickness provides stronger support in the first structural cavity 11, thereby improving the strength of the first structural cavity 11 surrounded by the first plate body 14, and further enabling the gas storage cavity 3 surrounded by the two cover plates 2 and the first structural cavity 11 to withstand greater pressure. In addition, by increasing the thickness of the first plate body 14, the overall strength of the rocker beam 1 can also be improved. In addition, since the thickness of the second plate body 15 is less than the thickness of the first plate body 14, the material cost can be reduced while ensuring the strength of the rocker beam 1, and the lightweight of the rocker beam 1 is facilitated.

[0041] In the embodiment of the present application, the gas storage cavity 3 surrounded by the first structural cavity 11 in the rocker beam 1 and the two cover plates 2 is used for gas storage, so that the rocker assembly has a gas storage function, without the need to set up a gas tank and the installation support, fastening bolts, nuts and other components required for installing the gas tank, thereby saving the space occupied by the gas tank and reducing the overall weight of the vehicle, achieving lightweight of the vehicle. In addition, the position of the gas storage is shifted from the bottom of the vehicle body to the rocker beam 1, thereby increasing the distance between the gas storage cavity 3 and the ground, and avoiding the risk of the gas tank scraping the ground. In addition, since it is not necessary to set up a gas tank and the installation support, fastening bolts, nuts and other components required for installing the gas tank at the rear of the vehicle body, the layout space at the rear of the vehicle body is saved, and the volume of the floor storage box is maximized. In addition, the gas tank and the installation support, fastening bolts, nuts and other components required for installing the gas tank are reduced on the vehicle, and the installation steps of these components are omitted, thereby reducing the overall cost of the vehicle and improving the assembly efficiency of the vehicle. In the embodiment of the present application, the gas storage cavity 3 is integrated into the rocker beam 1, thereby saving the space occupied by the gas tank, and ensuring that the gas storage cavity 3 can withstand sufficient pressure, and facilitating the lightweight of the vehicle.

[0042] In a preferred embodiment of the present application, referring to Figures 3 to 5 The first structural cavity 11 penetrates the rocker beam 1 along the length direction of the rocker beam 1, and the rocker beam 1 has two oppositely arranged end faces 13, and a positioning groove 131 is formed on each end face 13, and the cover plate 2 is connected in the positioning groove 131.

[0043] Specifically, the length direction of the rocker beam 1 can refer to Figure 1The two end faces 13 are oppositely arranged along the length direction of the rocker beam 1 in the direction indicated by the middle B arrow. The positioning groove 131 is specifically a stepped positioning groove. The shape and size of the positioning groove 131 are matched with the shape and size of the cover plate 2. When the cover plate 2 is assembled with the rocker beam 1, the cover plate 2 is first placed in the positioning groove 131, and then the cover plate 2 is connected with the rocker beam 1. In the embodiment of the present application, the positioning groove 131 can realize the positioning of the cover plate 2, ensure the accuracy of the position of the cover plate 2 when connected with the rocker beam 1, and further ensure the sealing of the gas storage cavity 3, thereby avoiding the situation that the gas storage cavity 3 is not sealed due to the misalignment of the cover plate 2 when connected with the rocker beam 1.

[0044] In a preferred embodiment of the present application, at least one reinforcing rib is arranged on the inner wall 141 of the first plate body 14, and / or at least one reinforcing rib is arranged on the outer wall 142 of the first plate body 14.

[0045] Specifically, the reinforcing rib arranged on the inner wall 141 of the first plate body 14 is located in the first structural cavity 11, and the reinforcing rib arranged on the outer wall 142 of the first plate body 14 is located outside the first structural cavity 11. The length direction of the reinforcing rib can be consistent with the length direction of the first structural cavity 11. The length direction of the reinforcing rib can also be consistent with the width direction of the rocker beam 1.

[0046] The total number of reinforcing ribs can be set according to actual needs, for example, the number of reinforcing ribs can be two, three, four, six, etc. The thickness of the reinforcing rib can be set according to actual needs, for example, the thickness of the reinforcing rib can be 2mm-3mm. In the embodiment of the present application, the reinforcing rib improves the strength of the first structural cavity 11, so that the first structural cavity 11 can withstand greater pressure, and avoids the deformation or damage of the first structural cavity 11 due to the excessive pressure of the gas stored in the first structural cavity 11.

[0047] In a preferred embodiment of the present application, the thickness of the first plate body 14 is greater than or equal to 2mm and less than or equal to 5mm.

[0048] Specifically, the thickness of the first plate body 14 can refer to Figure 5As shown in the diagram, the thickness of the first plate 14 (L1) can be 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. The thickness of the first plate 14 is preferably 5mm, in which case the thickness of the second plate 15 can be 2mm-3.5mm. When the thickness of the first plate 14 is greater than or equal to 2mm, it can provide sufficient structural support to ensure the strength of the first structural cavity 11, and the first plate 14 can better resist bending and twisting, thus preventing excessive deformation or damage to the first structural cavity 11 enclosed by the first plate 14. Conversely, when the thickness of the first plate 14 is less than or equal to 5mm, it can reduce costs, avoid material waste, and facilitate weight reduction. In summary, when the thickness of the first plate 14 is within the above range, the strength of the first structural cavity 11 is ensured without unnecessary weight increase due to excessive thickness.

[0049] In a preferred embodiment of the present invention, along the height direction of the sill beam 1, the first dimension of the cover plate 2 is greater than the first dimension of the first structural cavity 11, the difference between the first dimension of the cover plate 2 and the first dimension of the first structural cavity 11 is greater than or equal to 4 mm, and less than twice the thickness of the first plate 14; along the width direction of the sill beam 1, the second dimension of the cover plate 2 is greater than the second dimension of the first structural cavity 11, the difference between the second dimension of the cover plate 2 and the second dimension of the first structural cavity 11 is greater than or equal to 4 mm, and less than twice the thickness of the first plate 14.

[0050] Specifically, the height direction of threshold beam 1 can be referenced. Figure 3 The direction indicated by arrow C in the middle indicates the width direction of sill beam 1. Figure 3 The direction indicated by arrow D. When the thickness of the first plate 14 is 5mm, along the height direction of the sill beam 1, the difference between the first dimension of the cover plate 2 and the first dimension of the first structural cavity 11 is greater than or equal to 4mm and less than 10mm; along the width direction of the sill beam 1, the difference between the second dimension of the cover plate 2 and the second dimension of the first structural cavity 11 is greater than or equal to 4mm and less than 10mm. Preferably, along the height direction of the sill beam 1, the difference between the first dimension of the cover plate 2 and the first dimension of the first structural cavity 11 is 6mm; preferably, along the width direction of the sill beam 1, the difference between the second dimension of the cover plate 2 and the second dimension of the first structural cavity 11 is 6mm.

[0051] The first size of the cover plate 2 is greater than the first size of the first structural cavity 11, and the second size of the cover plate 2 is greater than the second size of the first structural cavity 11, so that the cover plate 2 can completely cover the end of the first structural cavity 11, thereby enabling the two cover plates 2 and the first structural cavity 11 to enclose a closed space, that is, the gas storage cavity 3 enclosed by the two cover plates 2 and the first structural cavity 11 is closed. When the difference between the first size of the cover plate 2 and the first size of the first structural cavity 11 is greater than or equal to 4 mm, and the difference between the second size of the cover plate 2 and the second size of the first structural cavity 11 is greater than or equal to 4 mm, the connection width of the cover plate 2 and the single side of the end surface 13 of the rocker beam 1 is greater than or equal to 2 mm, so that the cover plate 2 and the end surface 13 of the rocker beam 1 have sufficient connection width, thereby ensuring the connection firmness of the cover plate 2 and the rocker beam 1. When the difference between the first size of the cover plate 2 and the first size of the first structural cavity 11 is less than twice the thickness of the first plate body 14, and the difference between the second size of the cover plate 2 and the second size of the first structural cavity 11 is less than twice the thickness of the first plate body 14, the connection width of the cover plate 2 and the single side of the end surface 13 of the rocker beam 1 is less than the thickness of the first plate body 14, at this time, the edge of the cover plate 2 does not exceed the first plate body 14, which ensures the connection width between the cover plate 2 and the end surface 13 of the rocker beam 1 while avoiding material waste.

[0052] In summary, when the size of the cover plate 2 meets the above requirements, the cover plate 2 can cover the end of the first structural cavity 11 to ensure the sealing of the gas storage cavity 3, and the cover plate 2 and the end surface 13 of the rocker beam 1 have sufficient connection width, thereby ensuring the connection firmness of the cover plate 2 and the rocker beam 1.

The height of the first structural cavity 11 refers to the size of the first structural cavity 11 in the height direction of the rocker beam 1. The height of the reinforcing rib protruding from the first plate body 14 is preferably less than or equal to half of the height of the first structural cavity 11. When the height of the reinforcing rib is within the above range, the reinforcing effect on the first plate body 14 is ensured, and the first structural cavity 11 is avoided from being divided into small cavities that are not connected.

[0054] In a preferred embodiment of the present application, the depth of the positioning groove 131 is greater than or equal to 2 mm and less than or equal to 4 mm, and the thickness of the cover plate 2 is greater than or equal to the depth of the positioning groove 131.

[0055] Specifically, the depth of the positioning groove 131 can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. The preferred depth of the positioning groove 131 is 3mm. The thickness of the cover plate 2 can be 3mm, 4mm, 5mm, etc. When the depth of the positioning groove 131 is greater than or equal to 2mm, it provides sufficient embedding depth for the cover plate 2. The thickness of the cover plate 2 is greater than or equal to the depth of the positioning groove 131, that is, the thickness of the cover plate 2 is greater than or equal to 2mm, to ensure the strength of the cover plate 2, and a thicker cover plate 2 can withstand greater pressure, reducing the risk of deformation or damage.
