[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0034] Unless otherwise specified, the length direction of the vehicle described below is the X direction, that is, the front and rear direction of the vehicle, the width direction of the vehicle is the Y direction, that is, the left and right direction of the vehicle, and the height direction of the vehicle is the Z direction, that is, the up and down direction of the vehicle.

[0035] Reference below Figure 1-Figure 5 A lower vehicle body assembly 100 according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 5 As shown, the lower body assembly 100 according to the embodiment of the utility model includes: a lower body 10, a mounting structure 20 and a battery pack 30.

[0037] The lower body 10 includes a floor frame 11 and two body rocker beams 12 spaced apart in the width direction of the vehicle 1000, the mounting structure 20 is located between the two body rocker beams 12 and connected to the floor frame 11, the battery pack 30 is connected to the mounting structure 20, and at least a portion of the shell of the battery pack 30 and the floor frame 11 together constitute a body floor, wherein in the width direction of the vehicle 1000, an installation space is defined between the battery pack 30 and the body rocker beam 12, and the exhaust pipe of the engine of the vehicle 1000 is suitable for being installed in the installation space.

[0038] Thus, the battery pack 30 is mounted on the mounting structure 20, and the mounting structure 20 is connected to the floor frame 11, so that there will be a certain gap between the battery pack 30 and the body sill beam 12 in the width direction of the vehicle 1000, thereby forming an installation space for installing the exhaust pipe of the engine of the vehicle 1000, and at the same time, part of the shell of the battery pack 30 will form the body floor together with the floor frame 11, which can save space in the height direction of the vehicle 1000 and increase the comfort of the passengers.

[0039] For example, the floor frame 11 is arranged around the battery pack 30 along the circumference of the battery pack 30, and the floor frame 11 is connected to the inner side (the inner side is the side facing the inside of the vehicle 1000) of the vehicle body rocker beam 12 through the overlapping flange 111, and the mounting structure 20 is between the two vehicle body rocker beams 12 and connected to the floor frame 11. In this way, after the battery pack 30 is connected to the mounting structure 20, the shell of the battery pack 30 can form a vehicle body floor together with the floor frame 11, and at the same time, a certain gap will be formed between the battery pack 30 and the vehicle body rocker beam 12 to form an installation space for installing the exhaust pipe of the engine.

[0040] In the related art, the battery pack 30 of a pure electric vehicle can also be arranged between the body rocker beams 12 of the vehicle 1000 and the shell of the battery pack 30 can become the body floor. However, when the same arrangement is arranged in a hybrid vehicle 1000, the arrangement of the exhaust pipe of the engine will be affected.

[0041] When the battery pack 30 in this embodiment is arranged in the hybrid vehicle 1000 , it can provide installation space for the exhaust pipe of the engine, thereby making it more convenient to arrange the battery pack 30 .

[0042] According to the lower body assembly 100 of the embodiment of the utility model, at least part of the shell of the battery pack 30 thereof constitutes the vehicle body floor together with the floor frame 11, so that the battery pack 30 and the lower body 10 can be integrated into a design, so that the shell of the battery pack 30 assumes part of the function of the vehicle body floor, so as to increase the ground clearance of the vehicle 1000, and in the width direction of the vehicle 1000, an installation space for arranging the exhaust pipe of the engine is defined between the battery pack 30 and the vehicle body rocker beam 12, so as to reduce the difficulty of arranging the exhaust pipe of the engine.

[0043] In other embodiments, when the overlapping flange 111 of the floor frame 11 is connected to the inner side of the body rocker beam 12, the overlapping flange 111 is folded to extend in the height direction of the vehicle 1000, so that the overlapping flange 111 fits better with the side of the body rocker beam 12 facing the interior of the vehicle 1000, and the connection can be more stable. The connection form can be a welding connection, which can ensure the connection strength of the floor frame 11.

[0044] In some embodiments, Figure 1-Figure 2 As shown, the mounting structure 20 is constructed as an annular structure.

[0045] Therefore, the mounting structure 20 constructed as an annular structure can provide more connection points for the battery pack 30, so that the connection between the battery pack 30 and the mounting structure 20 can be more stable.

[0046] In some embodiments, Figure 1-Figure 5 As shown, the mounting structure 20 is configured as a mounting beam, and a weight-reducing cavity 21 is formed in the mounting beam.

[0047] For example, the weight-reducing cavity 21 will be open toward the floor frame 11. By closing the weight-reducing cavity 21 through the floor frame 11, the airtightness of the vehicle body floor can be enhanced. At the same time, the weight-reducing cavity 21 provided in the mounting beam can reduce the weight of the mounting beam and realize the lightweight of the lower body 10. The weight-reducing cavity 21 can also absorb the noise generated by the vehicle 1000 during driving, thereby improving the passenger experience.

[0048] Furthermore, when the battery pack 30 is connected to the mounting beam using connecting bolts, the weight-reducing cavity 21 can avoid the bolts to prevent interference between the bolts and the floor frame 11 , thereby making the installation of the battery pack 30 more convenient.

[0049] Therefore, a weight-reducing cavity 21 is formed in the mounting structure 20 constructed as a mounting beam. The weight-reducing cavity 21 can enhance the airtightness of the vehicle body floor, and at the same time can reduce the weight of the lower body assembly 100 to achieve lightweight lower body assembly 100. The weight-reducing cavity 21 can also serve as a force transmission channel of the lower body assembly 100 to improve the safety of the vehicle 1000, and can also absorb some noise generated by the vehicle 1000 when driving.

[0050] In some embodiments, Figure 1-Figure 2 As shown, a connecting flange 22 for connecting with the floor frame 11 is provided on the side of the mounting beam facing the floor frame 11 .

[0051] Thus, the connecting flange 22 where the mounting beam is connected to the floor frame 11 makes it more convenient to connect the mounting beam to the floor frame 11 during assembly, thereby improving assembly efficiency.

[0052] In some embodiments, Figure 1-Figure 2 As shown, the mounting beam includes a mounting cross beam 23 extending along the length direction of the vehicle 1000 , and / or the mounting beam includes a mounting longitudinal beam 24 extending along the width direction of the vehicle 1000 .

[0053] It should be noted that the mounting beam may include a mounting cross beam 23, or the mounting beam may include a mounting longitudinal beam 24, or the mounting beam includes a mounting cross beam 23 and a mounting longitudinal beam 24. Preferably, in this example, the mounting beam includes a mounting cross beam 23 and a mounting longitudinal beam 24, and the mounting cross beam 23 extends along the length direction of the vehicle 1000, and the mounting longitudinal beam 24 extends along the width direction of the vehicle 1000. In this way, when the battery pack 30 is connected to the mounting beam, it is connected in both the length direction and the width direction of the vehicle 1000, which can improve the connection stability of the battery pack 30.

[0054] Therefore, the mounting beam includes the mounting cross beam 23 and the mounting longitudinal beam 24 , so that there are more connection points when the battery pack 30 is connected to the mounting beam, which can improve the connection stability of the battery pack 30 .

[0055] Furthermore, the mounting cross beam 23 extends along the length direction of the vehicle 1000, and the mounting longitudinal beam 24 extends along the width direction of the vehicle 1000, so that the mounting cross beam 23 and the mounting longitudinal beam 24 are connected end to end to form a ring-shaped mounting beam, which can make the mounting beam more stable when set on the vehicle 1000.

[0056] In some embodiments, Figure 1-Figure 5 As shown, the shell includes a box body 31 and an upper cover 32, the box body 31 is connected to the mounting structure 20, the upper cover 32 is connected to the box body 31, and at least a portion of the upper cover 32 and the floor frame 11 together constitute the vehicle body floor; wherein, the mounting surface of the battery pack 30 is flush with the upper surface of the box body 31.

[0057] It should be noted that the box body 31 of the battery pack 30 is connected to the mounting structure 20 and thus fixed in the lower body assembly 100, and an upper cover 32 is also connected to the box body 31. When the upper cover 32 forms a vehicle body floor together with the floor frame 11, it can partially form a vehicle body floor together with the floor frame 11, or all form a vehicle body floor together with the floor frame 11. Preferably, in the present embodiment, the upper cover 32 forms the vehicle body floor together with the floor frame 11, which can improve the utilization rate of the upper cover 32 and thus reduce the weight of the entire vehicle.

[0058] Furthermore, the upper surface of the box body 31 is flush with the mounting surface of the battery pack 30, which makes it easier to align the upper cover 32 when forming the vehicle body floor with the floor frame 11, thereby improving the comfort of the passengers. At the same time, the upper cover 32 and the floor frame 11 forming the vehicle body floor can save materials and increase the Z-direction space of the vehicle 1000, thereby further improving the passenger experience.

[0059] Thus, the box body 31 of the battery pack 30 is connected to the mounting structure 20, and at least a portion of the upper cover 32 connected to the box body 31 can form a vehicle body floor together with the floor frame 11, which can save materials and reduce the weight of the entire vehicle, while also increasing the Z-direction space of the vehicle 1000 and improving the passenger experience.

[0060] In some embodiments, Figure 5 As shown, a connecting frame 33 is provided on the outer peripheral wall of the box body 31 , and the connecting frame 33 is detachably connected to the mounting structure 20 via a connecting piece 34 .

[0061] It should be noted that the connecting member 34 can be constructed as a connecting bolt, so that the box body 31 is easier to connect with the mounting structure 20, and the assembly efficiency can also be improved, which is more convenient to operate in subsequent maintenance.

[0062] Furthermore, the connecting member 34 may also be constructed in other forms. For example, the connecting member 34 may be constructed as a pin for connection. Preferably, in the present embodiment, the connecting member 34 is constructed as a connecting bolt.

[0063] Thus, the connecting frame 33 is connected to the mounting structure 20 via the connecting piece 34, which can effectively improve the assembly efficiency, thereby improving the production efficiency, and also making subsequent maintenance work easier.

[0064] In other embodiments, the connecting member 34 is constructed as a connecting bolt, and the nut 35 of the connecting bolt is arranged in the weight-reducing cavity 21. This can save installation space, thereby increasing the Z-direction space of the vehicle 1000. At the same time, the nut 35 is arranged in the weight-reducing cavity 21 to make assembly more convenient.

[0065] In some embodiments, the lower body assembly 100 further includes a gasket.

[0066] The gasket is sleeved on the connecting member 34 and clamped between the connecting frame 33 and the mounting structure 20 .

[0067] Therefore, the gasket sandwiched between the connecting frame 33 and the mounting structure 20 can provide a buffer for the connecting member 34, so that the connecting member 34 can be more stable during connection.

[0068] In some embodiments, Figure 1-Figure 2 As shown, the lower vehicle body assembly 100 further includes a sealing member 40 .

[0069] The sealing member 40 is sandwiched between the connecting frame 33 and the mounting structure 20 , and the sealing member 40 is located on the inner side of the gasket.

[0070] It should be noted that the seal 40 can be a sealing strip with an annular structure, and the annular sealing strip is arranged on the connecting frame 33. At the same time, the annular sealing strip is located on the side of the gasket facing the interior space in the horizontal direction. In this way, when the connecting frame 33 is connected to the mounting structure 20, it can play a circumferential sealing effect, thereby realizing the sealing of the passenger compartment, which can effectively isolate the noise when the vehicle 1000 is driving.

[0071] Among them, the sealing strip is clamped on the inner side of the gasket. When connected, the thickness of the gasket can be controlled to adjust the compression amount of the sealing strip, so that the sealing strip can seal the passenger compartment within a suitable compression range.

[0072] Furthermore, the seal 40 may also be constructed as a sealing sheet and disposed on the battery pack 30. Of course, the seal 40 may also be constructed in other forms. Preferably, in the present embodiment, the seal 40 is constructed as an annular sealing strip.

[0073] Thus, the seal 40 can seal the passenger compartment and isolate the noise generated when the vehicle 1000 is running.

[0074] The utility model also provides a vehicle 1000 .
