Description

Technical Field

[0001] This invention relates to the field of vehicle engineering technology, specifically to a sunken power battery bracket assembly and a vehicle thereof. Background Technology

[0002] With the deepening aging of China's population, the demand for pure electric low-floor city buses is becoming increasingly strong. Due to space constraints, these vehicles typically place the power battery on the roof. Because of the significant mass of the power battery, this arrangement raises the vehicle's center of gravity, negatively impacting lateral stability. Therefore, minimizing the height of the power battery placement would lower the center of gravity of the pure electric low-floor city bus, improving driving stability and thus protecting passenger safety. Consequently, there is an urgent need for a recessed power battery mount assembly and vehicle to address these issues. Summary of the Invention

[0003] To address the technical problem that pure electric low-floor city buses typically place their power batteries on the roof, which raises the vehicle's center of gravity due to the large mass of the batteries, thus compromising lateral stability, this invention provides a recessed power battery bracket assembly and vehicle. The integrated design of the base and the vehicle's roof frame reduces the weight of the roof frame. The power battery is fixed in the middle of the support, significantly reducing the height of the power battery on the vehicle's roof and also lowering the vehicle's center of gravity. Ultimately, this improves the vehicle's driving stability and overall lightweight design, while also ensuring passenger safety.

[0004] The present invention provides a sunken power battery bracket assembly, including a base and two support components. The two support components are fixedly mounted on the base and arranged symmetrically. Each support component includes a support seat, which is fixedly mounted on the base. The height of the horizontal plane where the middle part of the support seat is located is lower than the height of the horizontal plane where the base is located. The power battery is fixedly mounted in the middle part of the support seat.

[0005] Furthermore, the base includes two outer longitudinal beams and three connecting crossbeams. The two outer longitudinal beams are spaced apart and parallel to each other. One connecting crossbeam passes through the middle of the two outer longitudinal beams, and the remaining two connecting crossbeams are fixedly installed at both ends of the two outer longitudinal beams. Each connecting crossbeam is perpendicular to the outer longitudinal beam. A limiting longitudinal beam is fixedly installed in the middle of the three connecting crossbeams. The limiting longitudinal beam is located in the middle of the two outer longitudinal beams and is parallel to the outer longitudinal beams. Each support seat is fixedly installed on the limiting longitudinal beam and the two outer longitudinal beams. The base is assembled from the limiting longitudinal beam, the two outer longitudinal beams, and the three connecting crossbeams.

[0008] Furthermore, each of the support components also includes two anti-collision beams, which are respectively fixedly mounted at both ends of the first mounting beam and the two second mounting beams. The two anti-collision beams on each support component are located above the two outer mounting plates, and the power battery is located between the two anti-collision beams. The anti-collision beams protect the power battery, reducing the external impact on the power battery when the vehicle rolls over.

[0009] Furthermore, each of the aforementioned anti-collision beams includes an anti-collision main beam, a first longitudinal beam, and two second longitudinal beams. The first longitudinal beam is fixedly disposed in the middle of the anti-collision main beam, and both ends of the anti-collision main beam are curved.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-8 As shown in Embodiment 1, a sunken power battery bracket assembly includes a base 1 and two support components. The two support components are fixedly mounted on the base 1 and arranged symmetrically. Each support component includes a support seat 2, which is fixedly mounted on the base 1. The horizontal plane of the middle part of the support seat 2 is lower than the horizontal plane of the base 1 (i.e., a sunken design). The power battery 5 is fixedly mounted in the middle of the support seat 2. The support seat 2 can hold two power batteries 5. In this embodiment, two support seats 2 are provided, but the number of support seats 2 is not limited, and the size of the base 1 is not limited. Various assembly methods can be used to adapt to the installation requirements of different models and quantities of power batteries 5.

[0019] Assembly process of the recessed power battery bracket assembly: Two support seats 2 are fixedly mounted on the base 1 and arranged symmetrically. The power batteries 5 are fixedly mounted in the middle of the support seats 2, and a total of four power batteries 5 are fixed on the two support seats 2 respectively. Since the horizontal plane of the middle of the support seat 2 is lower than the horizontal plane of the base 1, after the power batteries 5 are fixed in the middle of the support seat 2, the horizontal plane of the power batteries 5 is lower than the horizontal plane of the base 1, thus reducing the arrangement height of the power batteries 5.

[0020] The base 1 is welded and fixed to the roof frame of the vehicle. After the base 1 is fixed, the mounting surface of the power battery 5 will be flush with the upper plane of the roof frame of the vehicle. The height of the mounting surface of the power battery 5 will be the same as or even lower than the height of the roof skin of the vehicle (but the power battery 5 still protrudes, and a battery decorative cover will be installed on the power battery 5).

[0021] Compared to the commonly seen battery mounts mounted on top of vehicles, the sunken battery mount assembly in this embodiment integrates the base 1 with the vehicle's roof frame, reducing the weight of the roof frame. The battery 5 is fixed in the middle of the support 2, which not only greatly reduces the height of the battery 5 on the vehicle roof but also significantly lowers the vehicle's center of gravity, ultimately improving the vehicle's driving stability and overall vehicle weight reduction, while also ensuring passenger safety.

[0022] In one possible implementation, the base 1 includes two outer longitudinal beams 11 and three connecting crossbeams 12. The two outer longitudinal beams 11 are spaced apart and parallel to each other. One connecting crossbeam 12 passes through the middle of the two outer longitudinal beams 11, and the remaining two connecting crossbeams 12 are fixedly disposed at both ends of the two outer longitudinal beams 11. Each connecting crossbeam 12 is perpendicular to the outer longitudinal beam 11. A limiting longitudinal beam 13 is fixedly disposed in the middle of the three connecting crossbeams 12. The limiting longitudinal beam 13 is located in the middle of the two outer longitudinal beams 11 and is parallel to the outer longitudinal beams 11. Each support seat 2 is fixedly disposed on the limiting longitudinal beam 13 and the two outer longitudinal beams 11. In this embodiment, the base 1 is assembled from the limiting longitudinal beam 13, the two outer longitudinal beams 11, and the three connecting crossbeams 12. The limiting longitudinal beam 13, the outer longitudinal beams 11, and the connecting crossbeams 12 are at the same horizontal level. The limiting longitudinal beam 13 passes through the connecting crossbeam 12 located in the middle. The limiting longitudinal beam 13, the outer longitudinal beams 11, and the connecting crossbeams 12 are all welded and fixed to the vehicle's roof frame. Preferably, the two ends of the connecting crossbeams 12 are curved to further facilitate their fixation to the vehicle's roof frame. The limiting longitudinal beam 13, the two outer longitudinal beams 11, and the three connecting crossbeams 12 can serve as part of the vehicle's roof frame, reducing the weight of the roof frame and thus lowering the vehicle's center of gravity.

[0023] In one possible implementation, each support base 2 includes a first mounting beam 21, two second mounting beams 22, and three mounting plates 23. The three mounting plates 23 are spaced apart and parallel to each other. The first mounting beam 21 is fixedly disposed in the middle of the three mounting plates 23, and the two second mounting beams 22 are respectively fixedly disposed at both ends of the three mounting plates 23. The first mounting beam 21 and each second mounting beam 22 are perpendicular to the mounting plates 23. The middle of each of the three mounting plates 23 is fixedly disposed on a limiting longitudinal beam 13, and the two ends of each mounting plate 23 are respectively fixedly disposed on two outer longitudinal beams 11. The horizontal plane of each mounting plate 23 is lower than the horizontal plane of the base 1. The power battery 5 is fixedly disposed on the three mounting plates 23. In this embodiment, the support base 2 is assembled from the first mounting beam 21, the two second mounting beams 22, and the three mounting plates 23. The three mounting plates 23 are all fixedly mounted on the limiting longitudinal beam 13 at their middle parts, and each mounting plate 23 is fixedly mounted on two outer longitudinal beams 11 at both ends, thus fixing the support base 2 to the base 1. The height of the middle part of the support base 2, i.e., the horizontal plane where the three mounting plates 23 are located, is lower than the height of the horizontal plane where the base 1 is located. The power battery 5 is fixedly mounted on the three mounting plates 23, thereby reducing the height of the power battery 5.

[0024] In one possible implementation, each mounting plate 23 includes two mounting sub-plates 231, which are inverted U-shaped. One end of each mounting sub-plate 231 is fixedly connected by a first mounting bracket 24, and the other end of each mounting sub-plate 231 is fixedly provided with a second mounting bracket 25. A first mounting beam 21 is fixedly mounted on three first mounting brackets 24, and each second mounting beam 22 is fixedly mounted on three second mounting brackets 25 located on the same side. All three first mounting brackets 24 are fixedly mounted on a limiting longitudinal beam 13, and all three second mounting brackets 25 located on the same side are fixedly mounted on an outer longitudinal beam 11. The power battery 5 is fixedly mounted on the three mounting sub-plates 231 located on the same side, and the power battery 5 is located between the first mounting beam 21 and the second mounting beam 22. In this embodiment, the mounting plate 23 is assembled from the first mounting bracket 24, the two mounting sub-plates 231, and the second mounting bracket 25. The first mounting bracket 24 and the second mounting bracket 25 are key components for realizing the recessed design of the power battery 5. The first mounting beam 21 is fixedly mounted on three first mounting brackets 24, and each second mounting beam 22 is fixedly mounted on three second mounting brackets 25 located on the same side. Finally, the first mounting beam 21, two second mounting beams 22, and three mounting plates 23 are assembled to form the support base 2. The three first mounting brackets 24 are fixedly mounted on the limiting longitudinal beam 13, and the three second mounting brackets 25 located on the same side are fixedly mounted on an outer longitudinal beam 11, thus fixing the support base 2 to the base 1. The height of the horizontal plane of each mounting plate 23 is lower than the height of the horizontal plane of the base 1, that is, the height of the horizontal plane of each mounting sub-plate 231 is lower than the height of the horizontal plane of the base 1. The power battery 5 is fixedly mounted on the three mounting sub-plates 231 located on the same side, thereby reducing the height of the power battery 5.

[0025] In one possible implementation, each support assembly further includes two anti-collision beams 3. The two anti-collision beams 3 on each support assembly are respectively fixed at both ends of the first mounting beam 21 and the two second mounting beams 22. The two anti-collision beams 3 on each support assembly are located above the two outer mounting plates 23. The mounting plate 23 located in the middle position on each support assembly may not have an anti-collision beam 3. The power battery 5 is located between the two anti-collision beams 3. The anti-collision beams 3 protect the power battery 5, reducing the external impact on the power battery 5 when the vehicle rolls over.

[0026] In one possible implementation, each of the anti-collision beams 3 includes an anti-collision main beam 31, a first longitudinal beam 32, and two second longitudinal beams 33. The first longitudinal beam 32 is fixedly disposed in the middle of the anti-collision main beam 31, and the two ends of the anti-collision main beam 31 are curved. The two second longitudinal beams 33 are respectively fixedly disposed in the two ends of the anti-collision main beam 31. Tripods 34 are fixedly disposed at the bottom of the first longitudinal beam 32 and the two second longitudinal beams 33. The three tripods 34 are respectively fixedly disposed at the same end of the first mounting beam 21 and the two second mounting beams 22. In this embodiment, the anti-collision beam 3 is assembled from the anti-collision main beam 31, the first longitudinal beam 32, and the two second longitudinal beams 33. The tripods 34 on the first longitudinal beam 32 are fixedly disposed at the end of the first mounting beam 21, and the tripods 34 on each of the second longitudinal beams 33 are fixedly disposed at the end of the second mounting beam 22.

[0027] As one possible implementation, each of the first mounting brackets 24 is an inverted U-shape, and an extension plate 241 is fixedly provided on both outer walls of each of the first mounting brackets 24. Each extension plate 241 is located below one end of the mounting sub-plate 231, and each extension plate 241 is fixedly connected to one end of the mounting sub-plate 231. The first mounting beam 21 is fixedly provided on the top of the three first mounting brackets 24, and the inverted U-shaped grooves on the three first mounting brackets 24 are all engaged with the limiting longitudinal beam 13.

[0028] One end of the mounting plate 231 is fixedly connected to the first mounting bracket 24 via the extension plate 241. Preferably, the extension plate 241 is provided with a connecting hole, and one end of each mounting plate 231 is provided with a first mounting hole. A first bolt passes through the first mounting hole and the connecting hole and is fixedly connected to the first nut.

[0029] Preferably, each first mounting bracket 24 has a first screw hole at its top, the first mounting beam 21 is U-shaped, and each first mounting beam 21 has multiple second screw holes. The second screw holes on the first mounting beam 21 are fixedly connected to the first screw holes by second bolts. The two ends of the first mounting beam 21 are also fixedly connected to the tripod 34 on the first longitudinal beam 32. That is, the second bolt passes through the tripod 34, the second screw hole and the first screw hole on the first longitudinal beam 32 in sequence and is fixedly connected.

[0030] The inverted U-shaped grooves on the three first mounting brackets 24 are all engaged with the limiting longitudinal beam 13. The limiting longitudinal beam 13 limits the three first mounting brackets 24, thereby fixing the support 2 to the base 1 and preventing the support 2 from swaying left and right. The limiting longitudinal beam 13 is inverted U-shaped, and the inverted U-shaped grooves on the first mounting brackets 24 match the top surface and two sides of the limiting longitudinal beam 13, allowing the inverted U-shaped grooves on the first mounting brackets 24 to engage with the limiting longitudinal beam 13.

[0031] In one possible implementation, each of the second mounting brackets 25 includes a first mounting plate 251, a second mounting plate 253, a third mounting plate 254, and an inclined plate 252 fixedly disposed between the first mounting plate 251 and the second mounting plate 253. The height of the horizontal plane where the second mounting plate 253 is located is greater than the height of the horizontal plane where the third mounting plate 254 is located, and the height of the horizontal plane where the third mounting plate 254 is located is greater than the height of the horizontal plane where the first mounting plate 251 is located. Each of the first mounting plates 251 is located below the other end of the mounting sub-plate 231, and each of the first mounting plates 251 is fixedly connected to the other end of the mounting sub-plate 231. Each of the second mounting beams 22 is fixedly disposed on the top of the three second mounting plates 253 located on the same side. Each of the inclined plates 252 is provided with an arc-shaped slot, and each of the arc-shaped slots is engaged with the outer longitudinal beam 11. Each of the third mounting plates 254 is fixedly connected to the outer longitudinal beam 11.

[0032] The other end of the mounting plate 231 is fixedly connected to the second mounting bracket 25 via the first mounting plate 251. Preferably, the other end of the mounting plate 231 is provided with a second mounting hole, the first mounting plate 251 is provided with a first positioning hole, and a third bolt passes through the second mounting hole and the first positioning hole and is fixedly connected to the third nut.

[0033] Preferably, both ends of the mounting plate 231 are provided with third mounting holes, which are located between the first and second mounting holes. The power battery 5 is mounted on the mounting plate 231 through the third mounting holes. The extension plate 241 is at the same height as the horizontal plane of the first mounting plate 251 and is lower than the horizontal plane of the base 1. The power battery 5 is fixedly mounted on the three mounting plates 231 located on the same side, thereby reducing the height of the power battery 5. At the same time, the mounting plate 231 can also strengthen the vehicle's roof frame.

[0034] The second mounting plate 253 is provided with a third screw hole. The second mounting beam 22 is U-shaped and is provided with multiple fourth screw holes. The fourth screw holes on the second mounting beam 22 are fixedly connected to the third screw holes by fourth bolts. The two ends of the second mounting beam 22 are also fixedly connected to the tripod 34 on the second longitudinal beam 33. That is to say, the fourth bolt passes through the tripod 34, the fourth screw hole and the third screw hole on the second longitudinal beam 33 in sequence and is fixedly connected.

[0035] The arc-shaped slot on the inclined plate 252 is engaged with the outer longitudinal beam 11. The outer longitudinal beam 11 limits and supports the second mounting bracket 25, thereby fixing the support seat 2 to the base 1.

[0036] In one possible implementation, each of the outer longitudinal beams 11 is fixedly provided with a plurality of fixing plates 111, and each of the third mounting plates 254 is located above the fixing plates 111 and fixedly connected to the fixing plates 111. The fixing plates 111 are provided with fixing holes, and the third mounting plates 254 are provided with second positioning holes. The fifth bolt passes through the second positioning hole and the fixing hole and is fixedly connected to the fifth nut.

[0037] like Figure 9 As shown in Embodiment 2, a vehicle includes a vehicle body 4 and a power battery 5, and also includes a recessed power battery bracket assembly as described in any of the above embodiments. The base 1 of the recessed power battery bracket assembly is fixedly mounted on the top frame of the vehicle body 4, and the power battery 5 is fixedly mounted on a support seat 2 on the recessed power battery bracket assembly. The base 1 is fixed to the top frame of the vehicle. After the base 1 is fixed, the mounting surface of the power battery 5 will be flush with the upper plane of the vehicle's top frame, and the height of the mounting surface of the power battery 5 will be the same as or even lower than the height of the vehicle's roof skin. Compared to the commonly used brackets that mount the power battery 5 on top of the vehicle, the recessed power battery bracket assembly of this embodiment integrates the base 1 with the vehicle's top frame. The power battery 5 is fixed in the middle of the support seat 2, thereby reducing the height of the power battery 5 on the vehicle's roof, thus lowering the center of gravity of the vehicle (pure electric low-floor city bus), ultimately improving the vehicle's driving stability and overall lightweight design, and also ensuring passenger safety.

[0038] In this embodiment, the vehicle has a sunken power battery bracket assembly, which lowers the height of the power battery 5, thereby reducing the vehicle's center of gravity. This improves the vehicle's driving stability and overall lightweight design, while also ensuring passenger safety.
