As a result, when an electric vehicle is involved in a collision, it cannot effectively disperse the collision force and prevent it from acting on the battery, thus making it difficult to protect the battery.

[0026] In some embodiments, the connecting rod includes a plurality of first connecting rods spaced apart between the crossbeam and the subframe, and the support device further includes a connecting plate that is fixedly connected to the first connecting rods and the crossbeam.

[0031] In some embodiments, the crossbeam further includes a third portion interconnected with the second portion, and the connecting plate further includes a third plate body connected to the second plate body, wherein the third portion is fixedly connected to the third plate body.

[0032] In the above technical solution, the contact area between the connecting plate and the crossbeam is relatively large, which can improve the connection stability between the support device and the energy cabin frame and facilitate the transmission of external forces on the energy cabin frame.

[0034] In the above technical solution, the fastener connection is firm and reliable, and at the same time, it is easy to quickly align and install the support device with the energy cabin frame, which can improve installation efficiency.

[0035] In some embodiments, the energy compartment frame includes longitudinal beams disposed at the middle of the crossbeams along the width axis of the vehicle frame.

[0036] In the above technical solution, multiple first connecting rods are arranged along the extension direction of the longitudinal beam on one side of the energy cabin frame, which improves the effect of absorbing the collision energy of the energy cabin frame.

[0037] In some embodiments, the subframe includes two first beams spaced apart and two second beams disposed between the first beams, and the support device is fixedly connected to the first beam of the two first beams closest to the energy compartment frame.

[0047] In some embodiments, the second connecting rod is arranged perpendicular to the width axis of the vehicle frame.

[0048] In the above technical solution, the first connecting rod and the second connecting rod are perpendicular to each other, which helps to increase the overall rigidity of the support device, enabling it to better resist deformation and displacement, thereby maintaining the stability and safety of the support device.

[0079] New energy vehicles have rapidly become popular in the domestic market, and the safety of using new energy vehicles is the most important consideration for users.

[0080] The vehicle includes a subframe, which can be seen as the skeleton of the front and rear axles and is a component of the front and rear axles. In the event of a collision, the subframe is easily damaged, and the huge impact energy is transferred through the subframe to the reinforcing beams near the battery pack, thus causing damage to its internal structure.

[0081] The battery pack of an electric vehicle, as its core power source, is not only expensive but also subject to extremely high safety requirements. However, existing electric vehicle frame designs have several shortcomings, primarily inadequate transmission of frontal collision forces, poor structural stability, and a tendency for excessive stress on the vehicle's crossbeams, leading to deformation. Furthermore, due to this inadequate force transmission, the impact force cannot be effectively dispersed during a collision to prevent it from reaching the battery, thus failing to adequately protect it.

[0082] Therefore, how to optimize the transmission path of collision force in the chassis design to ensure that collision energy can be quickly and evenly distributed to other non-critical areas of the vehicle body, thereby minimizing the impact on the battery device, has become a key issue that urgently needs to be addressed to improve the safety performance of electric vehicles.

[0083] Based on the above considerations, in order to solve or alleviate the problem of unreasonable transmission of external forces by the vehicle frame, this application provides a vehicle frame, including a subframe, an energy compartment frame, and a support device. The energy compartment frame is connected to the subframe, and the support device connects the energy compartment frame and the subframe on the width centerline of the vehicle frame.

[0084] In such a frame, the support device connects the crossbeams of the energy compartment frame and the subframe respectively. When either the energy compartment frame or the subframe is impacted, the support device absorbs the external force and prevents some of the external force from being transmitted to the other, thus protecting the energy compartment frame.

[0085] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0086] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cell assemblies housed within the housing.

[0087] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0088] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0089] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0090] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0091] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0092] In some embodiments of this application, the energy compartment is a battery device 100. The battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0093] Please refer to Figure 2 , Figure 2 This is an exploded structural diagram of a battery device 100 provided in some embodiments of this application. The battery device 100 includes a housing 70 and a battery cell 10, with the battery cell 10 housed within the housing 70. The housing 70 provides a closed space for the battery cell 10, and the housing 70 can adopt various structures.

[0094] Firstly, in some embodiments, please refer to Figure 3 This application provides a vehicle frame 400, which includes a subframe 41, an energy compartment frame 42, and a support device 43. The energy compartment frame 42 is connected to the subframe 41. On the width centerline V of the vehicle frame 400, the support device 43 connects the energy compartment frame 42 and the subframe 41.

[0095] In the technical solution of this application embodiment, the support device 43 connects the crossbeam 422 of the energy cabin frame 42 and the subframe 41 respectively. On the width centerline V of the frame 400, the support device 43 connects the energy cabin frame 42 and the subframe 41. By absorbing external forces through the support device 43, the energy cabin frame 42 can be protected.

[0096] Specifically, the frame 400 includes front and rear subframes 41 and an energy compartment frame 42 located between the front and rear subframes 41, the energy compartment frame 42 being used to fix and protect the vehicle's energy compartment.

[0097] The energy cabin frame 42 encloses the energy cabin's containment space 421, thereby fixing and protecting the energy cabin.

[0098] The energy compartment frame 42 is connected to the subframe 41. Meanwhile, the support device 43 connects the energy compartment frame 42 and the subframe 41 on the width centerline V of the frame 400.

[0099] like Figure 3As shown, the width centerline V of the frame 400 is parallel to the front-rear direction of the frame 400.

[0100] The support device 43 is located between the energy compartment frame 42 and the subframe 41. It can effectively absorb some energy and has a certain protective effect on the energy compartment frame 42. It can prevent the energy compartment frame 42 from being subjected to external forces, thereby reducing the amount of misalignment between the energy compartment and the energy compartment frame 42 and reducing the damage to the energy compartment.

[0101] Furthermore, when the energy compartment frame 42 is subjected to an external force from front to back, the external force is transmitted from the energy compartment frame 42 to the subframe 41 along the width axis V of the frame 400. The support device 43 can also block some of the external force from being transmitted to the subframe 41 by absorbing energy, thus providing a certain degree of protection for the subframe 41.

[0102] Conversely, when the energy compartment frame 42 is subjected to an external force from rear to front, the external force is transmitted from the subframe 41 to the energy compartment frame 42 along the width axis V of the frame 400. The support device 43 can also block some of the external force from being transmitted to the energy compartment frame 42 by absorbing energy, thus providing a certain degree of protection for the energy compartment frame 42.

[0103] The misalignment between the energy cabin and its frame 42 can be defined as the relative displacement between them. Excessive misalignment will cause the frame 42 to lose its function of securing and protecting the energy cabin, resulting in damage to the energy cabin.

[0104] In some embodiments, the support device 43 includes at least one connecting rod 431, which connects the energy cabin frame 42 and the subframe 41 respectively.

[0105] In the above technical solution, along the longitudinal direction of the vehicle 1000, the connecting rod 431 is located at the middle position on one side of the energy compartment frame 42, and the middle position of the energy compartment frame 42 is supported and strengthened by the connecting rod 431. Furthermore, the connecting rod 431 can absorb part of the impact energy, thereby blocking part of the external force from being transmitted between the energy compartment frame 42 and the subframe 41.

[0106] Specifically, along the front-rear direction of the frame 400, the energy compartment frame 42 is relatively weak at the position of the width centerline V of the frame 400. The two end faces 4311 of the connecting rod 431 are connected to the energy compartment frame 42 and the subframe 41 respectively. That is, the extension direction of the connecting rod 431 is parallel to the width centerline V of the frame 400.

[0107] The connecting rod 431 mainly bears the force in the direction of V, which is parallel to the width centerline of the frame 400. The extension direction of the connecting rod 431 is parallel to the width centerline of the frame 400, which can make the connecting rod 431 have better rigidity and load-bearing capacity when subjected to external force in the direction of V, which is parallel to the width centerline of the frame 400, and has a relatively good absorption effect on the force generated by external force.

[0108] Optionally, the connecting rod 431 includes a hollow tube. This allows for a lighter overall weight of the connecting rod 431, minimizing its impact on the weight of the frame 400 itself.

[0109] Optionally, the connecting rod 431 includes a square tube with a square cross-section. The square cross-section gives the connecting rod 431 good bending and torsional resistance in all directions. At the same time, the square cross-section of the connecting rod 431 is less prone to deformation when subjected to lateral forces, thereby improving the overall stiffness.

[0110] Optionally, the connecting rod 431 includes a circular tube with a circular cross-section. The circular cross-section allows the connecting rod 431 to distribute stress more evenly, reducing the possibility of stress concentration, thereby enabling the connecting rod 431 to have better support when subjected to external forces.

[0111] Optionally, the connecting rod 431 may be made of materials including but not limited to steel, aluminum alloy, carbon fiber, titanium alloy, and other high-strength, lightweight materials.

[0112] In some embodiments, please combine Figure 4 The connecting rod 431 includes a first connecting rod 432, and multiple first connecting rods 432 are arranged parallel to each other on one side of the energy cabin frame 42.

[0113] In the above technical solution, multiple first connecting rods 432 are arranged in parallel to each other, which makes the support device 43 have high rigidity and reliability, and at the same time has a good effect on dispersing external forces.

[0114] Specifically, multiple first connecting rods 432 are arranged on one side of the energy cabin frame 42, and the contact area between them is relatively larger. Thus, the first connecting rods 432 provide better support for the energy cabin frame 42.

[0115] Optionally, in one embodiment, a plurality of first connecting rods 432 are spaced apart along the width direction of the energy compartment frame 42 and disposed between the subframe 41 and the energy compartment frame 42. The plurality of first connecting rods 432 provide more support points for the energy compartment frame 42, and when external force is applied to the energy compartment frame 42, the transmission and distribution of external force are more uniform, thereby providing a relatively better protection effect for the energy compartment frame 42.

[0116] Optionally, in one embodiment, a plurality of first connecting rods 432 are arranged parallel to each other and spaced apart, with the spacing between any two first connecting rods 432 being the same. This results in a more uniform distribution of external forces when the energy cabin frame 42 is subjected to stress.

[0117] Optionally, in one embodiment, a plurality of first connecting rods 432 are arranged parallel to each other and spaced apart, with a different spacing between each pair of first connecting rods 432. For example, the spacing between the first connecting rods 432 near the width axis V of the frame 400 is smaller, while the spacing between the first connecting rods 432 away from the width axis V of the frame 400 is larger. This provides better support and reinforcement for the middle part of the energy compartment frame 42.

[0118] In some embodiments, please combine Figure 3 and Figure 4 Multiple first connecting rods 432 are symmetrically arranged along the width centerline V of the frame 400.

[0119] In the above technical solution, the support device 43 connects the energy compartment frame 42 and the subframe 41 on the width centerline V of the frame 400, so that the force distribution effect of the support device 43 on the middle part of the energy compartment frame 42 is more uniform.

[0120] Specifically, multiple first connecting rods 432 are symmetrically arranged along the width centerline V of the frame 400, which makes the support device 43 have high rigidity and reliability, and at the same time has a good effect on dispersing external forces.

[0121] Multiple first connecting rods 432 are symmetrically arranged on one side of the energy compartment frame 42 along the width axis V of the frame 400. On both sides of the width axis V of the frame 400, the effect of external force is evenly distributed, which can prevent the energy compartment frame 42 from shifting, bending or breaking under the action of external force to a certain extent.

[0122] Optionally, in one embodiment, the support device 43 includes a connecting rod 431, the axis of the connecting rod 431 along its length is in a straight line with the width centerline V along the frame 400, and the two end faces 4311 of the connecting rod 431 are respectively connected to the energy compartment frame 42 and the subframe 41, so that the connecting rod 431 can reinforce and support the energy compartment frame 42.

[0123] Optionally, in one embodiment, the plurality of first connecting rods 432 are arranged parallel to each other and symmetrically along the width axis V of the frame 400. This allows the plurality of first connecting rods 432 to be subjected to more even force.

[0124] Optionally, in one embodiment, the support device 43 includes two connecting rods 431, which are symmetrically arranged along the width centerline V of the frame 400, so that the supporting force on the energy cabin frame 42 is uniform and symmetrical. This can realize that the connecting rods 431 have a reinforcing and supporting effect on the energy cabin frame 42.

[0125] Optionally, in one embodiment, when the support device 43 includes two or more connecting rods 431, the width centerline V of the plurality of connecting rods 431 as a whole is on a straight line with the width centerline V of the frame 400.

[0126] It should be noted that symmetrical arrangement means that the multiple first connecting rods 432 are symmetrical along the width axis V of the frame 400. This can be understood as the spacing between the axes along the length direction of the first connecting rods 432 being basically the same. Here, "basically the same" means that the arrangement of the first connecting rods 432 can have a certain distance and angular error. Furthermore, structures that have little impact on the mass, shape, or position of the first connecting rods 432 can be provided. For example, the first connecting rods 432 may include reinforcing ribs, positioning parts, etc. Even if their positions on each first connecting rod 432 are different, it can still be considered that the multiple first connecting rods 432 are symmetrical along the width axis V of the frame 400. Alternatively, to match the structure of the subframe 41 or energy compartment frame 42, the length of the first connecting rods 432 or their connection position with the subframe 41 or energy compartment frame 42 may change accordingly. In this case, it can also be considered that the multiple first connecting rods 432 are symmetrical along the width axis V of the frame 400.

[0127] In some embodiments, please combine Figure 5 The first connecting rod 432 includes two opposing end faces 4311 and a side face 4312 connecting the two end faces 4311. The two end faces 4311 are respectively connected to the energy compartment frame 42 and the subframe 41.

[0128] In the above technical solution, the first connecting rod 432 contacts the energy compartment frame 42 and the subframe 41 through the end face 4311, which makes the first connecting rod 432 more stable under force.

[0129] Specifically, when the end face 4311 of the connecting rod 423 contacts the energy compartment frame 42 and the subframe 41 respectively, the contact area is maximized, which enhances the stability of the connection and helps resist the transmission of external forces or torque, ensuring the stability and reliability of the connection between the first connecting rod 432 and the energy compartment frame 42 and the subframe 41.

[0130] When subjected to large loads or dynamic loads, the end face 4311 of the connecting rod 423 is connected to the energy compartment frame 42 and the subframe 41 respectively, which can more effectively distribute stress and prevent loosening or damage at the connection.

[0131] In some embodiments, please combine Figure 3 The support device 43 also includes a connecting plate 433, which is fixedly connected to the connecting rod 431 and the energy cabin frame 42.

[0132] In the above technical solution, the connecting plate 433 has the function of reinforcing and protecting the energy cabin frame 42.

[0133] Specifically, the connecting plate 433 can increase the contact area between the connecting rod 431 and the energy cabin frame 42. In the case of multiple connecting rods 431, the connecting plate 433 can fix multiple connecting rods 431 together, which facilitates the unified installation of multiple connecting rods 431.

[0134] In some embodiments, please combine Figure 7 The connecting rod 431 includes a plurality of first connecting rods 432, which are parallel to each other and spaced apart on the connecting plate 433.

[0135] In the above technical solution, the connecting plate 433 can be fixedly connected to multiple first connecting rods 432, which facilitates the unified installation of multiple first connecting rods 432 and enables the connecting plate 433 and the first connecting rods 432 to be quickly and reliably connected.

[0136] Specifically, the connecting plate 433 is fixedly connected to the first connecting rod 432. Multiple first connecting rods 432 are pre-fixed to the connecting plate 433, which facilitates the unified installation of multiple first connecting rods 432, thereby making it more convenient to install the support device 43 onto the frame 400.

[0137] Meanwhile, when the first connecting rod 432 is fixedly connected to the connecting plate 433, multiple first connecting rods 432 can be arranged in parallel by using a positioning device or other positioning methods.

[0138] In some embodiments, please combine Figure 4 and Figure 5 The connecting plate 433 includes a first plate 4331 and a second plate 4332 that are connected to each other. The first plate 4331 is fixedly connected to at least a portion of the end face 4311 of the first connecting rod 432, and the second plate 4332 is fixedly connected to at least a portion of the side face 4312 of the first connecting rod 432.

[0139] In the above technical solution, a firm connection between the connecting plate 433 and the first connecting rod 432 can be achieved, thereby improving the overall rigidity and support reliability of the support device 43.

[0140] Specifically, at least a portion of the end face 4311 of the first plate 4331 is connected to the end face 4311 of the first connecting rod 432, meaning the area of ​​the surface where the first plate 4331 contacts the end face 4311 of the first connecting rod 432 can be greater than, equal to, or less than the area of ​​the end face 4311 of the first connecting rod 432. At least a portion of the side face 4312 of the second plate 4332 is fixedly connected to the side face 4312 of the first connecting rod 432, meaning the area of ​​the surface where the second plate 4332 contacts the side face 4312 of the first connecting rod 432 can be greater than, equal to, or less than the area of ​​the side face 4312 of the first connecting rod 432.

[0141] Optionally, in one embodiment, the first connecting rod 432 is a square tube, and the first plate 4331 and the second plate 4332 are basically perpendicular to each other. In this way, the contact area between the first body and the second plate 4332 and the first connecting rod 432 can be larger, thereby making the fixation between the two more secure and reliable.

[0142] In some embodiments, the connecting plate 433 and the energy cabin frame 42 are connected by at least one of the following connection methods: welding, fastener connection, and adhesive connection.

[0143] In the above technical solution, the connecting plate 433 and the energy cabin frame 42 can be connected quickly and reliably.

[0144] Optionally, in one embodiment, the connecting plate 433 and the energy cabin frame 42 are connected by welding. Welding creates a high-strength connection point, ensuring the stability of the connection between the connecting plate 433 and the energy cabin frame 42 under external force conditions. Furthermore, since no additional fasteners 434, such as bolts or nuts, are required during welding, the cost is relatively low.

[0145] Optionally, in one embodiment, the connecting plate 433 and the energy cabin frame 42 are connected by fasteners. The fasteners 434 include, but are not limited to, bolts, nuts, screws, rivets, etc. The fastener connection is detachable and highly reliable, which facilitates subsequent maintenance, inspection and parts replacement.

[0146] The fastener connection ensures high precision and constant fastening force between the connecting plate 433 and the energy chamber frame 42. In addition, the fastener connection has high strength and durability and can withstand large loads and vibrations, thereby improving the safety and reliability of the overall structure.

[0147] Optionally, in one embodiment, the connecting plate 433 and the energy cabin frame 42 are connected by adhesive bonding. Adhesive bonding uses adhesive to tightly bond the connecting plate 433 and the energy cabin frame 42 together, resulting in a simple and cost-effective connection method. Adhesive bonding eliminates the need for complex processes such as drilling and riveting, simplifying the assembly process and improving production efficiency.

[0148] In some embodiments, please combine Figure 4 The connecting plate 433 has a first connecting hole 4334, the energy cabin frame 42 has a second connecting hole, and the support device 43 also includes a fastener 434, which passes through the first connecting hole 4334 and the second connecting hole to fix the connecting plate 433 and the energy cabin frame 42.

[0149] In the above technical solution, the fastener connection is firm and reliable, and at the same time, it is easy to quickly align and install the support device 43 with the energy cabin frame 42, which can improve the installation efficiency.

[0150] Specifically, the fastener 434 connection ensures a high-precision and constant fastening force between the connecting plate 433 and the energy cabin frame 42. In addition, the fastener 434 connection has high strength and durability, and can withstand large loads and vibrations, thereby improving the safety and reliability of the overall structure.

[0151] In some embodiments, please combine Figure 3 and Figure 6 The energy cabin frame 42 includes a crossbeam 422, and the support device 43 includes at least one connecting rod 431. The connecting rod 431 connects the energy cabin frame 42 and the subframe 41 respectively, and the connecting rod 431 is fixedly connected to the crossbeam 422.

[0152] In the above technical solution, the connecting plate 433 connects the crossbeam 422 and the connecting rod 431. The connecting rod 431 connects the crossbeam 422 in the middle and reinforces the middle of the crossbeam 422. To a certain extent, it can protect the crossbeam 422 from impact deformation.

[0153] Specifically, the energy cabin frame 42 includes two opposing crossbeams 422, and the energy cabin can be fixed between the two crossbeams 422. A first connecting rod 432 connects the crossbeams 422 at the middle, providing support and reinforcement to the middle of the crossbeams 422.

[0154] Optionally, the support device 43 can be connected to the crossbeam 422 of the energy compartment frame 42 near the front of the frame 400. Optionally, the support device 43 can be connected to the crossbeam 422 of the energy compartment frame 42 near the rear of the frame 400. Optionally, the support device 43 can be connected to the crossbeams 422 of the energy compartment frame 42 near both the front and rear of the frame 400.

[0155] The connecting plate 433 is fixedly connected to multiple connecting rods 431 and to the crossbeam 422. Compared to the connecting rods 431, the connecting plate 433 has a larger contact area with the crossbeam 422. When the connecting rods 431 are subjected to external forces, the connecting plate 433 can disperse the external forces, thus protecting the crossbeam 422. When the energy cabin frame 42 is subjected to external forces, the connecting plate 433 first provides support to the crossbeam 422, strengthening the middle part of the crossbeam 422.

[0156] In some embodiments, please combine Figure 3 and Figure 6 The connecting rod 431 includes a plurality of first connecting rods 432, which are spaced apart between the crossbeam 422 and the subframe 41. The support device 43 also includes a connecting plate 433, which is fixedly connected to the first connecting rods 432 and the crossbeam 422.

[0157] In the above technical solution, the first connecting rod 432 supports the crossbeam 422, and the connecting plate 433 disperses external forces.

[0158] Specifically, the connecting plate 433 is fixedly connected to multiple first connecting rods 432 and to the crossbeam 422. Compared to the first connecting rods 432, the connecting plate 433 has a larger contact area with the crossbeam 422. When the first connecting rods 432 are subjected to external forces, the connecting plate 433 can disperse the external forces, thus protecting the crossbeam 422. When the energy cabin frame 42 is subjected to external forces, the connecting plate 433 first provides support to the crossbeam 422, strengthening the middle part of the crossbeam 422.

[0159] Furthermore, the connecting plate 433 can disperse and transmit external forces to multiple first connecting rods 432, which helps to absorb the energy generated by external forces and prevents some of the external forces from continuing to be transmitted to the subframe 41.

[0160] In some embodiments, please combine Figure 5 The crossbeam 422 includes a first part 4221 and a second part 4222 that are connected to each other. The connecting plate 433 includes a first plate body 4331 and a second plate body 4332 that are connected to each other. The side of the first plate body 4331 facing the first connecting rod 432 is fixedly connected to at least a portion of the end face 4311 of the first connecting rod 432. The side of the second plate body 4332 facing the first connecting rod 432 is fixedly connected to at least a portion of the side surface 4312 of the first connecting rod 432.

[0161] The side of the first plate 4331 facing away from the first connecting rod 432 is fixedly connected to the first part 4221, and the side of the second plate 4332 facing away from the first connecting rod 432 is fixedly connected to the second part 4222.

[0162] In the above technical solution, a firm connection can be achieved between the connecting plate 433 and the first connecting rod 432 and the crossbeam 422, thereby improving the overall rigidity and support reliability of the support device 43.

[0163] Specifically, the connecting plate 433 can fully contact the crossbeam 422 and the first connecting rod 432, thereby firmly fixing the crossbeam 422 and the first connecting rod 432 through the connecting plate 433.

[0164] The connecting plate 433 can fully contact and almost completely fit the crossbeam 422, which can effectively reinforce the crossbeam 422 and help resist external forces. In addition, the large contact area between the connecting plate 433 and the crossbeam 422 is conducive to firmly fixing the connecting plate 433 and the first connecting rod 432 on it.

[0165] In some embodiments, please combine Figure 5 The crossbeam 422 also includes a third part 4223 that is interconnected with the second part 4222, and the connecting plate 433 also includes a third plate 4333 that is connected with the second plate 4332. The third part 4223 is fixedly connected to the third plate 4333.

[0166] In the above technical solution, the contact area between the connecting plate 433 and the crossbeam 422 is relatively large, which can improve the connection stability between the support device 43 and the energy cabin frame 42 and facilitate the transmission of external forces on the energy cabin frame 42.

[0167] Specifically, the connecting plate 433 contacts the crossbeam 422 and the third part 4223 of the energy cabin frame 42 through the first plate 4331, the second plate 4332, and the third plate 4333, respectively, so that the contact area between the connecting plate 433 and the energy cabin frame 42 is relatively large, and the effect of transmitting external forces between the two is better. At the same time, it also facilitates the fixing of the connecting plate 433 and the energy cabin frame 42.

[0168] Optionally, in one embodiment, the first plate 4331, the second plate 4332, and the third plate 4333 are manufactured from a single sheet metal through an integral forming process such as bending, stamping, and casting. This ensures a reliable connection between the first plate 4331, the second plate 4332, and the third plate 4333, while also facilitating processing.

[0169] In some embodiments, please combine Figure 4The first plate 4331, the second plate 4332 and the third plate 4333 are provided with a first connecting hole 4334, and the first part 4221, the second part 4222 and the third part 4223 are provided with a second connecting hole. The fastener 434 is fixedly connected to the first plate 4331, the second plate 4332 and the third plate 4333 and the first part 4221, the second part 4222 and the third part 4223 by passing through the first connecting hole 4334 and the second connecting hole.

[0170] In the above technical solution, the fastener connection is firm and reliable, and at the same time, it is easy to quickly align and install the support device 43 with the energy cabin frame 42, which can improve the installation efficiency.

[0171] Specifically, the fastener connection ensures high precision and constant fastening force between the connecting plate 433 and the crossbeam 422. In addition, the fastener connection has high strength and durability and can withstand large loads and vibrations, thereby improving the safety and reliability of the overall structure.

[0172] Furthermore, by providing a first connecting hole 4334 and a second connecting hole on the connecting plate 433 and the crossbeam 422, the middle position of the connecting plate 433 along the length direction can be determined according to the length of the connecting plate 433 and the distribution of the first connecting rods 432 on the connecting plate 433, thereby realizing that the support device 43 is set along the width centerline V of the frame 400.

[0173] In some embodiments, please combine Figure 3 The energy compartment frame 42 includes a longitudinal beam 424, which is disposed in the middle of the crossbeam 422 along the width centerline V of the frame 400.

[0174] In the above technical solution, multiple first connecting rods 432 are arranged on one side of the energy cabin frame 42 along the extension direction of the longitudinal beam 424, which has a better effect on absorbing the collision energy of the energy cabin frame 42.

[0175] Specifically, as an example, in an energy compartment collision test, when one side of the energy compartment frame 42 is impacted, the impact energy is transferred to the subframe 41 through the longitudinal beam 424. The support device 43 connects the crossbeam 422 and the subframe 41, and can support and reinforce the crossbeam 422 in the middle. While absorbing part of the impact energy, the support device 43 transfers the impact energy to the rear subframe 41, thereby achieving uniform distribution of the impact force. In this way, the support strength of the energy compartment frame 42 in the collision direction is strengthened, the misalignment between the energy compartment and the energy compartment frame 42 is reduced, and the damage to the energy compartment is reduced.

[0176] In some embodiments, please combine Figure 3The subframe 41 includes two first beams 411 spaced apart and two second beams 412 disposed between the first beams 411. The support device 43 is fixedly connected to the first beam 411 closest to the energy compartment frame 42 among the two first beams 411.

[0177] In the above technical solution, it is beneficial for the subframe 41 to transmit the external force to the first connecting rod 432.

[0178] Specifically, the subframe 41 includes two opposing first beams 411 and a second beam 412 located between the first beams 411 and fixedly connected to the first beams 411, forming a fixed frame for the rear compartment. The first beams 411 are fixedly connected to the first connecting rod 432.

[0179] When the energy cabin frame 42 is subjected to external force, part of the force is transmitted to the first beam 411 and the second beam 412 through the first connecting rod 432, so that the external force is evenly distributed, which helps to protect the energy cabin frame 42 and the subframe 41.

[0180] In some embodiments, the support device 43 includes at least one connecting rod 431, the energy cabin frame 42 includes a crossbeam 422, and the connecting rod 431 connects the crossbeam 422 and the first beam 411 respectively, so that the support assembly connects the energy cabin frame 42 and the subframe 41.

[0181] In the above technical solution, the connecting rod 431 is in direct contact with the first beam 411, which facilitates the transmission of external forces from the subframe 41 to the first connecting rod 432.

[0182] Specifically, the first beam 411 is fixedly connected to the connecting rod 431, serving as the fixed frame of the rear cabin. The connecting rod 431 connects the crossbeam 422 and the first beam 411 respectively. When the crossbeam 422 is subjected to external force, the connecting rod 431 can absorb part of the energy generated by the external force, and at the same time transfer part of the external force to the first beam 411 and the second beam 412, which helps to protect the energy cabin frame 42.

[0183] In some embodiments, please combine Figure 4 The connecting rod 431 includes a first connecting rod 432, and the support device 43 further includes a baffle 435, which connects the first beam 411 to at least one first connecting rod 432.

[0184] In the above technical solution, the baffle 435 connects the first beam 411 and the connecting rod 431. The baffle 435 has a certain strengthening effect on the first beam 411. At the same time, the baffle 435 has a certain function of absorbing and blocking external forces.

[0185] Specifically, the baffle 435 is fixedly connected to at least one first connecting rod 432, and is fixedly connected to the first beam 411. The baffle 435 can act as an intermediary for external force transmission, so that the force on the first connecting rod 432 can be more uniformly transmitted to the first beam, avoiding force concentration, thereby providing a protective effect for the first connecting rod 432 and the first beam 411, which helps to prolong the service life of the first connecting rod 432 and the first beam 411.

[0186] In some embodiments, the contact area between the baffle 435 and the first beam 411 is larger than the contact area between the first connecting rod 432 and the baffle 435.

[0187] In the above technical solution, the baffle 435 can increase the stressed area of the interaction force between the first connecting rod 432 and the first beam 411, thereby better dispersing external acting forces.

[0188] Specifically, the contact area between the baffle 435 and the first beam 411 is larger than the contact area between the first connecting rod 432 and the baffle 435. When the contact area between the baffle 435 and the first beam is large, the force can be more uniformly distributed on the contact surface, so the stress distribution on the contact surface between the baffle 435 and the first beam will be more uniform, reducing local stress concentration.

[0189] Meanwhile, the larger contact area helps to enhance the overall stability of the structure. The baffle 435 and the first beam 411 are less prone to deformation or damage when subjected to force

[0190] In some embodiments, please refer to Figure 8 , the connecting rod 431 includes a first connecting rod 432 and a second connecting rod 436. A plurality of first connecting rods 432 are arranged parallel to each other on one side of the energy cabin frame 42, and the second connecting rod 436 is arranged between every two first connecting rods 432, and connects the cross beam 422 of the energy cabin frame 42 or the sub-frame 41.

[0191] In the above technical solution, the combination of the first connecting rod 432 and the second connecting rod 436 reinforces the support device 43 and improves the reliability of the support device 43.

[0192] Specifically, the first connecting rod 432 and the second connecting rod 436 are connected to each other, and a certain angle may be formed between the first connecting rod 432 and the second connecting rod 436. The second connecting rod 436 has the function of supporting the first connecting rod 432 and enhancing the structural strength, which can improve the overall stiffness of the support device 43.

[0193] Wherein, the first connecting rod 432 and the second connecting rod 436 can be connected into a "grid-shaped" or "checkerboard-shaped" grid, so that the supporting device 43 has better bearing capacity for external forces and the overall stiffness is improved.

[0194] Optionally, in one embodiment, the first connecting rod 432 and the second connecting rod 436 are connected by welding. Welding creates a high-strength connection point, ensuring the stability of the connection between the first connecting rod 432 and the second connecting rod 436 under external force conditions. Furthermore, since no additional fasteners 434, such as bolts or nuts, are required during welding, the cost is relatively low.

[0195] Optionally, in one embodiment, the first connecting rod 432 and the second connecting rod 436 are connected by fasteners. The fasteners 434 include, but are not limited to, bolts, nuts, screws, rivets, etc. The fastener connection is detachable and highly reliable, which facilitates subsequent maintenance, inspection and replacement of parts.

[0196] The fastener connection ensures high precision and constant fastening force between the connecting plate 433 and the crossbeam 422. In addition, the fastener connection has high strength and durability and can withstand large loads and vibrations, thereby improving the safety and reliability of the overall structure.

[0197] Optionally, in one embodiment, the first connecting rod 432 and the second connecting rod 436 are connected by adhesive bonding. Adhesive bonding uses adhesive to tightly bond the first connecting rod 432 and the second connecting rod 436 together, resulting in a simple and cost-effective connection method. Adhesive bonding eliminates the need for complex processes such as drilling and riveting, simplifying the assembly process and improving production efficiency.

[0198] In some embodiments, please combine Figure 8 The second connecting rod 436 is set perpendicular to the width centerline V of the frame 400.

[0199] In the above technical solution, the first connecting rod 432 and the second connecting rod 436 are perpendicular to each other, which helps to increase the overall rigidity of the support device 43, enabling it to better resist deformation and displacement, thereby maintaining the stability and safety of the support device 43.

[0200] Specifically, the first connecting rod 432 is parallel to the width centerline V of the frame 400, and the second connecting rod 436 is perpendicular to the width centerline V of the frame 400. In this way, the first connecting rod 432 and the second connecting rod 436 can support and fix each other, preventing deformation of either the first connecting rod 432 or the second connecting rod 436 under external force. This strengthens the overall rigidity of the support device 43, improving its reliability and stability.

[0201] In some embodiments, please combine Figure 8 The support device 43 also includes a connecting plate 433, which is fixedly connected to the energy cabin frame 42 and the first connecting rod 432 and / or the second connecting rod 436.

[0202] In the above technical solution, the connecting plate 433 provides support and fixation for the first connecting rod 432 and the second connecting rod 436, which helps to enhance the overall rigidity of the support device 43.

[0203] Specifically, the connecting plate 433 increases the contact area between the first connecting rod 432 and the second connecting rod 436 and the energy cabin frame 42, while also providing support and fixation for the first connecting rod 432 and the second connecting rod 436. On the other hand, the connecting plate 433 is fixedly connected to the energy cabin frame 42, which provides support and reinforcement for the middle part of the energy cabin frame 42.

[0204] Optionally, in one embodiment, one end face 4311 of the first connecting rod 432 is connected to one side face 4312 of the second connecting rod 436, and the other side face 4312 of the second connecting rod 436 is fixed to the connecting plate 433, thereby realizing the fixed connection between the connecting plate 433 and the first connecting rod 432 and the second connecting rod 436.

[0205] Optionally, in one embodiment, one end face 4311 of the first connecting rod 432 and one side face 4312 of the second connecting rod 436 are fixedly connected to the connecting plate 433, while one end face 4311 of the second connecting rod 436 is connected to one side face 4312 of the first connecting rod 432. In this way, the connection between the first connecting rod 432, the second connecting rod 436 and the connecting plate 433 is more robust and reliable.

[0206] In some embodiments, please combine Figure 8 The support device 43 also includes a baffle 435, which is fixedly connected to the subframe 41 and the first connecting rod 432 and / or the second connecting rod 436.

[0207] In the above technical solution, the baffle 435 has a certain strengthening effect on the structure of the support device 43, and at the same time, the baffle 435 has a certain function of absorbing and blocking external forces.

[0208] Specifically, when the energy cabin frame 42 is subjected to external force, the external force is transmitted to the baffle 435 through the energy cabin frame 42, the first connecting rod 432 and the second connecting rod 436. The baffle 435 absorbs and disperses part of the force, thereby reducing the transmission of external force to the subframe 41, thus achieving the protection of the subframe 41.

[0209] As an example, in the crash test of the frame 400, the support device 43 serves as the final energy absorption and barrier barrier for the energy compartment. The force transmission path of the collision force on the frame 400 is as follows: the collision force is transmitted from the front end to the crossbeam 422 on the front side of the energy compartment frame 42, and then to the longitudinal beam 424 in the middle of the energy compartment frame 42. The longitudinal beam 424 then transmits the force to the crossbeam 422 on the rear side of the energy compartment frame 42, and finally to the support device 43 through the rear crossbeam 422. The support device 43 can absorb and block part of the impact energy and evenly transmit part of the collision force to the rear subframe 41 and the rear compartment.

[0210] The connecting plate 433 and the first connecting rod 432 are connected by riveting, thus connecting the first connecting rod 432 and the connecting plate 433 by riveting the riveted parts together. When the external force on the subframe 41 is transmitted forward, the baffle 435 blocks part of the external force from continuing to be transmitted forward, and the energy is further absorbed by the first connecting rod 432 and the second connecting rod 436, so as to achieve the protection of the energy compartment.
