[0029] Please refer to Figures 1 to 4 The roof longitudinal beam structure 100 of the present invention includes a longitudinal beam 10 and a power battery 12, with the power battery 12 disposed on the longitudinal beam 10.

[0030] The aforementioned roof longitudinal beam structure 100, by placing the power battery 12 on the longitudinal beam 10, can greatly improve the rigidity of the whole vehicle, simplify the structural design of the body frame, reduce the weight of the whole vehicle, and lower the height of the vehicle's center of gravity.

[0031] Specifically, in the corresponding vehicle, the roof longitudinal beam structure 100 is located on the left and right sides of the vehicle, and the left and right roof longitudinal beam structures 100 can be connected by the connecting plate 52 in the middle. (See reference...) Figures 1-4 , Figures 1-4 This is a schematic diagram of the connecting plate 52 and the left-side roof longitudinal beam structure 100. In this embodiment of the invention, the roof longitudinal beam structure 100 includes a longitudinal beam 10 and a power battery 12, with the power battery 12 mounted on the longitudinal beam 10. Thus, by mounting the power battery 12 on the longitudinal beams 10 on both sides of the vehicle body, the rigidity of the entire vehicle can be significantly improved, the structural design of the vehicle frame can be simplified, the overall vehicle weight can be reduced, and the overall vehicle center of gravity height can be lowered.

[0032] In some roof longitudinal beam structures 100, the power battery 12 is concentrated on the roof. This necessitates the design of additional mounting devices and structural reinforcement for the power battery 12 mounting area. Dynamic driving can cause additional damage to the power battery 12 mounting area, potentially leading to premature breakage of interior armrests and the vehicle frame. Furthermore, the harsh environment of the rooftop environment hinders temperature management, resulting in excessively high temperatures in summer and excessively low engine temperatures, leading to high overall vehicle energy consumption and making maintenance more difficult. This necessitates the design of additional coverings, resulting in additional costs.

[0033] In some embodiments, the power battery 12 can be a battery approximately 2 meters long. Two power batteries 12 on the roof longitudinal beam structure 100 can be connected by bolts, and the structure can be in series. The power battery 12 can be fixed using bolts. Alternatively, the power battery 12 can be placed vertically on the longitudinal beam structure 10. This helps to improve the bending stiffness of the vehicle body.

[0034] In some embodiments, the longitudinal beam 10 is provided with a receiving groove 14, in which the power battery 12 is at least partially located.

[0035] In this way, the power battery 12 can form an integral whole with the longitudinal beam 10, and the rigidity of the power battery 12 itself can greatly improve the rigidity of the whole vehicle.

[0036] Specifically, see Figure 1 and Figure 2 The left longitudinal beam 10 has a receiving groove 14 with an opening facing the right. The receiving groove 14 is used to receive the power battery 12, and the power battery 12 is at least partially located in the receiving groove 14. The power battery 12 can be placed vertically in the receiving groove 14. In this way, the rigidity of the power battery 12 can be greatly improved by combining its own rigidity.

[0037] In some embodiments, the roof longitudinal beam structure 100 satisfies the condition: Lmax≤3, where Lmax is the maximum ratio of the thickness of the power battery 12 to the depth of the accommodating groove 14.

[0038] Thus, at least one-third of the power battery 12 is located in the receiving slot 14, which facilitates the fixing of the power battery 12.

[0039] Specifically, Lmax≤3, where Lmax is the maximum ratio of the thickness of the power battery 12 to the depth of the receiving groove 14. Here, the thickness of the power battery 12 represents the size of the power battery 12 along the depth direction of the receiving groove 14. The maximum ratio of the thickness of the power battery 12 to the depth of the receiving groove 14, Lmax≤3, means that at least one-third of the power battery 12 is located in the receiving groove 14, which can ensure the effectiveness of the receiving groove 14 in accommodating the power battery 12 and facilitate the fixing of the power battery 12.

[0040] In some embodiments, the power battery 12 has at least one mounting portion 16 at its end in the height direction, and the mounting portion 16 is connected to the longitudinal beam 10 to fix the power battery 12.

[0041] This makes it easier to secure the power battery 12.

[0042] Specifically, see Figure 1 , Figure 2 and Figure 4 The power battery 12 has at least one mounting portion 16 at its vertical end, which is connected to the longitudinal beam 10 to fix the power battery 12. The vertical ends of the power battery 12 are also the upper and lower parts of the power battery 12 shown in the figure, and mounting portions 16 are provided at the upper and lower parts of the power battery 12. These mounting portions 16 are connected to the longitudinal beam 10 to fix the power battery 12. In some embodiments, the power battery 12 has two mounting portions 16 at its vertical end, meaning there is one mounting portion 16 at the top and one at the bottom of the power battery 12. The mounting portions 16 located at the top and bottom of the power battery 12 are fixedly connected to the longitudinal beam 10 to fix the power battery 12 on the longitudinal beam 10.

[0043] In some embodiments, the roof longitudinal beam structure 100 includes a mounting assembly 18, through which the power battery 12 is mounted on the longitudinal beam 10.

[0044] Thus, the mounting assembly 18 secures the power battery 12 to the longitudinal beam 10.

[0045] Specifically, see Figure 1 , Figure 2 and Figure 4 The roof longitudinal beam structure 100 may include multiple mounting components 18, through which the power battery 12 is mounted on opposite sides of the longitudinal beam 10. The power battery 12 of the left-side roof longitudinal beam structure 100 is mounted on the longitudinal beam 10 via multiple mounting components 18 on both the upper and lower sides. Some mounting components 18 are connected to the top of the power battery 12, and others are also connected to the top of the power battery 12. By mounting the power battery 12 on the longitudinal beam 10 of the roof longitudinal beam structure 100 via the mounting components 18, the power battery 12 can be removed or installed by installing or removing the mounting components 18 when needed, facilitating maintenance of the power battery 12.

[0046] In some embodiments, a first mounting groove 20 is provided on the longitudinal beam 10, and the mounting assembly 18 includes a mounting member 22 and a fixing member 24. A part of the mounting member 22 is located in the first mounting groove 20, and another part of the mounting member 22 can be connected to the mounting part 16 of the power battery 12. The fixing member 24 is fixedly connected to the mounting member 22 on one side of the power battery 12 to fix the power battery 12 on the longitudinal beam 10.

[0047] Thus, the mounting component 18 is mounted on the first mounting slide 20 to connect to and secure the power battery 12.

[0048] Specifically, see Figure 1 , Figure 2 and Figure 4 The left longitudinal beam 10 is provided with two first mounting grooves 20, one above the other. Each of the two first mounting grooves 20 has a mounting component 18 installed, which can be embedded and fixed into the first mounting groove 20. The mounting component 18 includes a mounting member 22 and a fixing member 24. A portion of the mounting member 22 is located in the first mounting groove 20, and the other portion of the mounting member 22 is connected to the power battery 12. The fixing member 24 is fixedly connected to the mounting member 22 on one side of the power battery 12 to secure the power battery 12 on the longitudinal beam 10. In some embodiments, the mounting member 22 can be a bolt, and the fixing member 24 can be a nut. The bolt is installed in the first mounting groove 20, the power battery 12 passes through the bolt, and the nut cooperates with the bolt to fix the power battery 12.

[0049] In some embodiments, the roof longitudinal beam structure 100 includes a duct plate 26, which connects to the longitudinal beam 10 and forms a duct 28 with the longitudinal beam 10, and the power battery 12 is at least partially located in the duct 28.

[0050] Thus, the power battery 12 is at least partially located in the air duct 28 formed by the air duct plate 26 and the longitudinal beam 10, which facilitates heat dissipation.

[0051] Specifically, see Figure 1 The air duct plate 26 can be a long plate extending along the length of the longitudinal beam 10, having two long sides. One long side of the air duct plate 26 is connected to a connecting plate 52 connected above the longitudinal beam 10, and the other long side is connected to the longitudinal beam 10 located below the power battery 12, forming an air duct 28 in which the power battery 12 is located. Thus, the power battery 12 located in the air duct 28 facilitates heat dissipation. In some embodiments, air conditioning air flows through the air duct 28, and the temperature of the power battery 12 can be regulated by utilizing the air conditioning air flowing through the air duct 28.

[0052] In some embodiments, the roof longitudinal beam structure 100 includes an air duct lock 30, and the air duct plate 26 is detachably connected to the longitudinal beam 10 via the air duct lock 30.

[0053] In this way, the air duct plate 26 is detachably connected to the longitudinal beam 10, which allows for quick inspection and maintenance of the power battery 12 and improves the testing efficiency of the power battery 12.

[0054] Specifically, see Figure 1The roof longitudinal beam structure 100 includes a duct lock 30. The duct plate 26 can be detachably connected to the longitudinal beam 10 through the duct lock 30, which facilitates the rapid inspection and maintenance of the power battery 12 and improves the testing efficiency of the power battery 12.

[0055] In some embodiments, the receiving groove 14 includes a side plate 32 and a top plate 34. The side plate 32 is connected to the top plate 34. The side plate 32 is disposed at the bottom of the receiving groove 14. The top plate 34 is disposed on the side of the receiving groove 14 near the top of the power battery 12. The longitudinal beam 10 includes a water guide plate 36. The water guide plate 36 is connected to the top plate 34. A water guide portion 38 is disposed at the end of the top plate 34 away from the water guide plate 36. The water guide portion 38, the top plate 34, and the water guide plate 36 form a water guide groove 40. The water guide groove 40 is inclined along the length direction of the longitudinal beam 10.

[0056] In this way, the water channel 40 formed by the water guide section 38, the top plate 34 and the water guide plate 36 can guide water out of the vehicle and prevent water from accumulating on the vehicle.

[0057] Specifically, see Figure 1 and Figure 2 A receiving groove 14 is disposed on the longitudinal beam 10, a side plate 32 is disposed at the bottom of the receiving groove 14, and a top plate 34 is disposed on the side of the receiving groove 14 near the top of the power battery 12. The side plate 32 is connected to the top plate 34. The longitudinal beam 10 connected to the top plate 34 is a water guide plate 36. A water guide section 38 is disposed at the end of the top plate 34 away from the water guide plate 36. The water guide section 38 extends away from the side where the power battery 12 is located. The water guide section 38, the top plate 34, and the water guide plate 36 form a water guide channel 40, which is inclined along the length of the longitudinal beam 10. The water guide channel 40 has a U-shaped cross-section and has a certain inclination angle along the vehicle body. In this way, water flowing down from the roof can be drained away through the U-shaped cross-section, preventing it from flowing into the vehicle and affecting the power battery 12 or other components. See reference. Figure 2 The water guide plate 36 can be an arc-shaped plate, which facilitates water diversion.

[0058] In some embodiments, the receiving groove 14 includes a side plate 32 and a bottom plate 42. The side plate 32 is disposed at the bottom of the receiving groove 14, and the bottom plate 42 is connected to the bottom end of the side plate 32. The power battery 12 is located in the space enclosed by the side plate 32 and the bottom plate 42. The bottom surface of the bottom plate 42 is provided with a fixing plate 44, and the fixing plate 44 is provided with a second mounting groove 46 for installing curtains.

[0059] Thus, the second mounting groove 46 can be used to install curtains.

[0060] Specifically, see Figure 1 and Figure 2The receiving groove 14 is disposed on the longitudinal beam 10, and the base plate 42 is disposed on the side of the receiving groove 14 near the bottom of the power battery 12. The base plate 42 is connected to the bottom end of the side plate 32, and the power battery 12 is located in the space enclosed by the side plate 32 and the base plate 42. The bottom surface of the base plate 42 is provided with a fixing plate 44, which has a second mounting groove 46 for installing curtains. Curtain hangers can be guided into the second mounting groove 46 so that the curtains can be installed on the second mounting groove 46.

[0061] In some embodiments, a second mounting groove 46 is provided on the longitudinal beam 10. The second mounting groove 46 is located below the power battery 12 and is used to install the curtain.

[0062] Thus, the second mounting groove 46 provided on the longitudinal beam 10 is located below the power battery 12 and is used to install the curtain.

[0063] Specifically, see Figure 1 , Figure 2 and Figure 4 The second mounting groove 46 on the longitudinal beam 10 is located below the power battery 12 and is used to install curtains.

[0064] In some embodiments, the bottom of the second mounting groove 46 is provided with a mounting hole 48, and the two opposite walls of the mounting hole 48 form a guide surface 50, which is used to guide the curtain hanger into the second mounting groove 46.

[0065] Thus, the guide surface 50 formed by the mounting hole 48 and the two hole walls facilitates the insertion of curtain hangers.

[0066] Specifically, see Figure 2 The mounting hole 48 at the bottom of the second mounting groove 46 is used to guide the curtain hanger. The guide surface 50 formed by the mounting hole 48 and the two hole walls facilitates the introduction of the curtain hanger.

[0067] The vehicle in this embodiment of the invention includes the roof longitudinal beam structure 100 in any of the above embodiments.

[0068] By placing the power battery 12 on the longitudinal beam 10, the rigidity of the vehicle can be greatly improved, the structural design of the body frame can be simplified, the weight of the vehicle can be reduced, and the height of the vehicle's center of gravity can be lowered.

[0069] Specifically, the aforementioned vehicles include, but are not limited to, pure electric vehicles, hybrid vehicles, range-extended electric vehicles, etc. In one embodiment, the vehicle may be a passenger car.
