[0024] Please refer to Figure 1 , this embodiment provides a power battery frame structure 100, including a placement rack 110, a first mounting bracket 120, and a connection plate 130; the placement rack 110 includes a first rack body 111 and a second rack body 112 arranged in a stacked manner; the first rack body 111 includes a plurality of first trays 1111 and a plurality of support plates 1112, and the plurality of support plates 1112 are arranged at intervals in the horizontal direction. One first tray 1111 is connected between two adjacent support plates 1112, and the first tray 1111 is used for placing the first power battery 140; the support plate 1112 is perpendicularly connected to the first tray 1111; the connection plate 130 is arranged at the end of the support plate 1112 along the stacking direction of the first rack body 111 and the second rack body 112; the second rack body 112 includes a plurality of second trays 1121, and the plurality of second trays 1121 are arranged at intervals in the vertical direction on the top of the first rack body 111, and the second tray 1121 is used for placing the second power battery 150; the first mounting bracket 120 is arranged between two adjacent second power batteries 150 and is used for fixedly connecting to the vehicle frame 210.

[0025] Specifically, as Figure 1As shown, the power battery frame structure 100 includes a placement rack 110 for placing power batteries. To improve the space utilization rate of the placement rack 110, the placement rack 110 includes a first frame body 111 disposed on the lower layer and a second frame body 112 disposed on the upper layer.

[0026] Among them, as Figure 2 shown, the first frame body 111 includes a plurality of first trays 1111 and a plurality of support plates 1112. During assembly, first, a first power battery 140 is assembled on each first tray 1111. Each first tray 1111 and the first power battery 140 disposed thereon are arranged at intervals in the horizontal direction to be in the same direction as the width direction of the vehicle frame 210. Then, the support plates 1112 are installed. The support plates 1112 are perpendicularly disposed with respect to the first trays 1111. The mounting plates and the first trays 1111 together enclose the frame structure of the first frame body 111, and support plates 1112 are also provided between two adjacent first power batteries 140, facilitating the later installation, disassembly, and maintenance of individual first power batteries 140 and improving the convenience of maintenance disassembly and assembly. The setting of the support plates 1112 not only plays a certain protective role for the first power batteries 140 but also plays a certain supporting effect for the subsequent setting of the second frame body 112, strengthening the stability of the power battery frame structure 100.

[0027] As Figure 1 、 Figure 3 and Figure 6 shown, the second frame body 112 includes a plurality of second trays 1121. During assembly, first, a second power battery 150 is assembled on each second tray 1121. Each second tray 1121 and the second power battery 150 disposed thereon are arranged at intervals in the vertical direction, that is, the extension direction of the gap between two adjacent second power batteries 150 is in the same direction as the extension direction of the vehicle frame 210. After the assembly is completed, the second trays 1121 and the second power batteries 150 disposed thereon are installed on the assembly assembly 118, facilitating the subsequent assembly with the first frame body 111.

[0028] Preferably, to facilitate the assembly of the second frame body 112 and the first frame body 111, lifting lugs are provided on the second copper bars at the mid-position of the second frame body 112. Through the lifting lugs, the second trays 1121 and the second power batteries 150 thereon can be lifted and placed on the first frame body 111. To further improve the assembly stability of the first frame body 111 and the second frame body 112, the second frame body 112 and the first frame body 111 are assembled and linked by bolts.

[0029] As Figure 4As shown, there is a gap between two adjacent second power batteries 150. In a specific embodiment of the present application, the number of the first power battery 140 and the second power battery 150 is three each, that is, there is a gap between every two of the three power batteries. Correspondingly, the vehicle frame 210 has two longitudinals arranged at intervals and at least one cross member for connecting the two longitudinals. Among them, the two longitudinals can be arranged in the gap between two adjacent second power batteries 150 to further improve the space utilization rate of the assembly. The first mounting bracket 120 is arranged between two adjacent second power batteries 150 and is used for fixedly connecting with the second mounting bracket 211 of the vehicle frame 210.

[0030] It should be noted that, first, in order to further improve the assembly efficiency and positioning accuracy of the power electric frame structure and the vehicle frame 210, in an implementable embodiment of the present application, the first mounting bracket 120 is provided with positioning holes, and the second mounting bracket 211 is correspondingly provided with positioning pins adapted to the positioning holes. During assembly, the assembly efficiency can be improved through the quick positioning of the positioning holes and the positioning pins, and the assembly stability is also improved to a certain extent.

[0031] Second, in an implementable embodiment of the present application, as Figure 1 and Figure 2 shown, the end parts of two adjacent support plates 1112 are respectively connected by an upper connection bracket 113 and a lower connection bracket 114; the upper connection bracket 113 and the lower connection bracket 114 are respectively arranged on the opposite sides of the support plate 1112 along the arrangement direction of the connection plate 130; the connection plate 130 is respectively connected to the connection surfaces of the upper connection bracket 113 and the lower connection bracket 114.

[0032] Through the arrangement of the upper connection bracket 113 and the lower connection bracket 114, the connection stability of the first frame body 111 can be further improved. The rigid connection between the upper connection bracket 113 and the lower connection bracket 114 and the end part of the support plate 1112 forms a three-dimensional support structure in the horizontal and vertical directions, thereby enhancing the overall stiffness and torsional resistance of the first frame body.

[0033] As Figure 1 and Figure 2 shown, the connection plate 130 is arranged at the end part of the support plate 1112 along the stacking direction, and the upper connection bracket 113 and the lower connection bracket 114 are respectively located on both sides of the connection plate 130, so that the force on the support plate 1112 in the vertical direction is evenly transmitted to the connection plate 130 through the brackets on both sides, avoiding structural deformation or stress concentration caused by unilateral force, and reducing the problem of insufficient strength of the vehicle frame 210 caused by uneven battery weight distribution.

[0034] Third, as Figure 1 and Figure 2As shown, in an implementable manner of the present application, at least one rubber buffer block 115 is provided between two adjacent support plates 1112. During the driving of a commercial vehicle, the torsion of the vehicle frame 210 or the bumps on the road surface may cause the support plates 1112 to vibrate. The rubber buffer block 115 absorbs the vibration energy through elastic deformation, reduces the mechanical stress generated by the vibration of the power battery, and reduces the risk of loosening of the internal circuits or structural components of the battery pack. Moreover, the rubber buffer block 115 can buffer the relative displacement between the support plates 1112, avoid damage to the battery tray or bracket caused by rigid collision, and extend the service life of the frame system.

[0035] Through the arrangement of the rubber buffer block 115, effective support can be provided for the first power battery 140, effective limit can be provided while avoiding structural failure, and abnormal noise caused by bumping can be prevented.

[0036] Fourth, in an implementable manner of the present application, as Figure 5 shown, at least one quick-release strengthening part 1111a is recessed in the side wall of the first tray 1111 towards the first power battery 140. In a specific implementation manner of the present application, quick-release strengthening parts 1111a are recessed on both opposite sides of the first tray 1111. Through the arrangement of the quick-release strengthening part 1111a, the installation and disassembly of each first tray 1111 and the first power battery 140 can be independent of each other, improving the disassembly and assembly efficiency.

[0037] The present application provides a power battery frame structure 100, including a placement rack 110, a first mounting bracket 120 and a connecting plate 130; the placement rack 110 includes a first frame body 111 and a second frame body 112 arranged in a stacked manner; the stacked design can make full use of the vertical space, and compared with the traditional arrangement on both sides of the frame, more batteries can be arranged in a limited chassis space, thereby improving space utilization and the volume energy density of the battery of the whole vehicle; the first frame body 111 includes a plurality of first trays 1111 and a plurality of support plates 1112, the plurality of support plates 1112 are arranged at intervals in the horizontal direction, and a first tray 1111 is connected between two adjacent support plates 1112, and the first tray 1111 is used to hold a first power battery 140; this structural design enables the first frame body 111 to be arranged in a horizontal direction. It has high rigidity. When the whole vehicle is in torsion condition, it can effectively reduce the stress of the first power battery 140 caused by the torsion of the frame 210, and improve the overall torsion resistance of the power battery frame structure 100. The support plate 1112 is vertically connected to the first tray 1111. The connecting plate 130 is arranged at the end of the support plate 1112 along the stacking direction of the first frame 111 and the second frame 112. The second frame 112 includes a plurality of second trays 1121, which are arranged at intervals on the top of the first frame 111 along the vertical direction. The second tray 1121 is used to hold the second power battery 150. The space is further expanded on the top of the first frame 111 to realize the arrangement of the upper vertical battery, further improve the space utilization, and meet the arrangement requirements of large-capacity power batteries. The first mounting bracket 120 is arranged between two adjacent second power batteries 150 and is used to be fixedly connected to the frame 210. The power battery frame structure 100 can improve the space utilization of the power battery frame, improve the passability of the vehicle chassis, and reduce the risk of collision of the power battery.

[0038] For example, Figure 3 As shown, one end of the connecting plate 130 is flush with the end of the supporting plate 1112 away from the second tray 1121, and the other end extends along the stacking direction of the first frame 111 and the second frame 112 to the top surface protruding from the second power battery 150; a pedal skeleton 116 is provided on the plane where the end of the connecting plate 130 away from the first frame 111 is located, and the pedal skeleton 116 is a rectangular frame structure; a plurality of skin fixing brackets 117 spliced ​​in sequence are provided in the frame of the pedal skeleton 116; the surfaces of the connecting plate 130, the pedal skeleton 116 and the skin fixing bracket 117 are covered with a skin 160.

[0039] Specifically, Figure 1 and Figure 3As shown, one end of the connecting plate 130 is flush with the end of the support plate 1112, forming a horizontal reference plane at the bottom layer of the first frame body 111, which facilitates the precise docking with the support plate 1112 through positioning pins and bolts; the other end extends upward to protrude above the top surface of the second power battery 150, enhancing the longitudinal supporting force of the connecting plate 130 on the second tray 1121 and preventing the middle part of the connecting plate 130 from sagging and deforming due to the gravity of the upper-layer battery. The connecting plate 130 protruding above the top surface of the second power battery 150 provides an installation base for the stepping skeleton 116 and the skin fixing bracket 117, avoiding additional support members occupying the chassis space and further improving the space utilization rate.

[0040] The stepping skeleton 116 with a rectangular frame structure forms a rigid plane, which can be directly stepped on by maintenance personnel for operation, eliminating the process of additionally installing an operation platform on the traditional vehicle frame, reducing the types and weights of components, and thus improving the integration and lightweight of the power battery frame structure 100. At the same time, the mechanical structure of the rectangular frame has strong stability. When bearing the stepping load, the stress is evenly dispersed through the four-side frame, avoiding the deformation of the skeleton or the rupture of the skin 160 caused by single-point stress, and providing reliable support for the skin 160.

[0041] The connecting plate 130, the stepping skeleton 116, and the skin fixing bracket 117 and the skin 160 form a closed cavity, protecting the batteries, pipelines, etc. inside the frame from being eroded by mud and water. The skin 160 is installed through bolts or buckles with the skin fixing bracket 117 set, improving the appearance consistency of the whole vehicle and reducing the air resistance during driving.

[0042] Optionally, as Figure 1 shown, the skin fixing bracket 117 includes a bracket frame 1171 and at least one cross beam bracket and at least one longitudinal beam bracket arranged in the bracket frame 1171, and the cross beam bracket is vertically connected to the longitudinal beam bracket. Through the arrangement of at least one cross beam bracket and at least one longitudinal beam bracket, a plurality of grid-like support structures in the shape of a Chinese character 'tian' are formed inside the skin fixing bracket 117, providing evenly distributed fixing points for the skin 160 and also improving the supporting force and stability.

[0043] Optionally, as Figure 1 and Figure 8 shown, the outer surface of the skin 160 is convexly provided with reinforcing ribs 161, and the number of the reinforcing ribs 161 can be multiple, and the multiple reinforcing ribs 161 are evenly distributed on the outer surface of the skin 160. Through the arrangement of the reinforcing ribs 161, the protection efficiency and reliability of the skin 160 are further improved.

[0044] In an implementable manner of the present application, as Figure 8As shown, a clamping plate 1172 is further provided on the bracket frame 1171 of the skin fixing bracket 117 corresponding to the position of the vehicle frame 210. The clamping plate 1172 is connected to the bracket frame 1171 through a rubber pad 170; the side edge of the vehicle frame 210 is arranged between the clamping plate 1172 and the bracket frame 1171.

[0045] Specifically, as Figure 8 shown, the rubber pad 170 is provided to have a preset interval between the clamping plate 1172 and the bracket frame 1171, and the clamping plate 1172 is arranged on the side of the bracket frame 1171 facing the first frame body 111; correspondingly, the opposite sides of the horizontal end face of the vehicle frame 210 extend outward to form horizontally arranged extension pieces. When the vehicle frame 210 is clamped in the gap between the two second power batteries 150, the extension pieces of the vehicle frame 210 can be clamped in the gap between the clamping plate 1172 and the bracket frame 1171, thereby providing a clear positioning reference for the connection between the vehicle frame 210 and the power battery frame structure 100, quickly aligning the side edge of the vehicle frame 210, reducing the alignment time during installation, and improving the assembly efficiency.

[0046] Moreover, the clamping plate 1172 and the bracket frame 1171 cooperate to clamp the extension piece, which can avoid the loosening risk that may occur in a single bolt connection. Especially under the condition of vehicle bumpiness, the clamping plate 1172 and the bracket frame 1171 cooperate to limit the lateral displacement of the side edge of the vehicle frame 210, enhancing the reliability of the connection between the power battery frame structure 100 and the vehicle frame 210.

[0047] The elastic characteristic of the rubber pad 170 can absorb the relative vibration between the vehicle frame 210 and the frame, preventing the direct contact between metal parts from generating friction noise; when the vehicle passes through a complex road surface, the vehicle frame 210 and the power battery frame structure 100 may generate a small angular deviation due to torsion, and the deformation ability of the rubber pad 170 can buffer the shear force between the two, avoiding the deformation or fracture of the clamping plate 1172 or the bracket frame 1171 caused by rigid collision, and being able to avoid the coating wear of the vehicle, prolonging the service life of the vehicle frame 210 and the frame.

[0048] It should be noted that in an implementable manner of the present application, as Figure 9 shown, the surface of the rubber pad 170 is further convexly provided with a clamping portion 171. Correspondingly, the bracket frame 1171 is provided with a clamping hole adapted to the clamping portion 171, and the rubber pad 170 can be quickly clamped in the clamping hole through the clamping portion 171, thereby improving the assembly efficiency.

[0049] In an implementable manner of the present application, as Figure 4 shown, the power battery frame structure 100 further includes a brake system air storage tank 180 and a charging socket 190. The brake system air storage tank 180 is hung on the side wall of the placement rack 110; the charging socket 190 is arranged on the top of the placement rack 110.

[0050] Specifically, as Figure 4 shown, the power battery frame structure 100 of the present application is combined with the independently arranged functional components in the transmission, avoiding the problems of space waste and complex pipelines caused by the scattered installation of each component. In traditional commercial vehicles, an air storage tank bracket and a charging socket 190 bracket need to be separately installed on both sides of the vehicle frame. However, in this design, through the integrated bearing of the power battery frame structure 100, the types and quantities of chassis components are reduced, and the assembly complexity is lowered; in addition, in such a setting method, components such as the support plate 1112 of the power battery frame structure 100 can be shared, avoiding the repeated setting of independent brackets, thereby reducing the vehicle weight and material cost.

[0051] As Figure 4 shown, the brake system air storage tank 180 is hung on the side wall of the placement rack 110, making use of the vertical space of the power battery frame structure 100 to avoid the air storage tank occupying the battery layout area inside the vehicle frame 210 or in the middle of the chassis, ensuring the maximization of the installation space of the power battery; moreover, after the air storage tank is hung on the side wall of the power battery frame structure 100, its center of gravity is close to the longitudinal beam of the vehicle frame 210, reducing the roll moment during vehicle driving and improving the driving stability.

[0052] As Figure 4 shown, the charging socket 190 is arranged on the top of the placement rack 110, which is easily accessible to the driver or charging personnel, improving the convenience and safety of the charging operation; and the charging socket 190 is higher than the chassis ground, reducing the risk of rain and mud splashing into the socket, and improving the use reliability and safety.

[0053] On the other hand, the present invention provides a vehicle, including a vehicle frame 210 and a power battery frame structure 100. The power battery frame structure 100 includes a first frame body 111 and a second frame body 112 arranged in a stacked manner.
