[0032] See also Figure 1 An embodiment of the present application provides a battery mounting structure 10 for mounting a battery 50 . The battery mounting structure 10 includes a base plate 20 , a tray structure 30 and a protective structure 40 .

[0033] Part of the vehicle rear floor 20 ′ is reused as the bottom plate 20 .

[0034] The tray structure 30 is fixedly connected to the bottom plate 20 , and the tray structure 30 is used to carry the battery 50 .

[0035] Part of the vehicle body assembly 40 ′ is reused as a part of the protective structure 40 , and the tray structure 30 is disposed inside the protective structure 40 .

[0036] The battery mounting structure 10, the vehicle battery assembly 100 and the vehicle provided in the embodiment of the present application, by reusing part of the vehicle rear floor 20' as the base plate 20 in the battery mounting structure 10, and reusing part of the vehicle body assembly 40' as the protective structure 40 in the battery mounting structure 10, the tray structure 30 is arranged in the protective structure 40, and the battery 50 is indirectly installed on the base plate 20 through the tray structure 30, it is possible to provide comprehensive mechanical protection and a stable connection relationship for the battery 50, and effectively improve the structural strength and rigidity near the battery 50 arrangement area.

[0037] Optionally, the battery 50 is a lithium battery for low-voltage power supply to cockpit instruments and meters in the vehicle, and the power supply voltage of the battery 50 is usually 12 V. Since a 12V lithium battery is prone to fire or explosion after being collided or squeezed, a battery mounting structure 10 with sufficient structural strength and rigidity needs to be arranged near the arrangement area of ​​the battery 50 to prevent the battery mounting structure 10 from being squeezed to the battery 50 due to the deformation of other structures of the vehicle due to collision, and the connection relationship between the battery 50 and the battery mounting structure 10 also needs to be sufficiently stable.

[0038] The rear floor 20' of the vehicle is the foundation of the entire vehicle body structure, and can bear the rear seats, spare tires and fuel tanks, etc. The rear floor 20' of the vehicle also affects the dimensions of the four-wheel alignment of the entire vehicle. In the related art, the rear floor 20' of the vehicle is supported by a steel bottom plate 20, and its strength and rigidity are ensured by pressing reinforcing ribs and convex and concave platforms on the main plate, which has high strength and rigidity and can provide the support and structural strength required by the vehicle.

[0039] Reusing part of the vehicle rear floor 20 ′ as the bottom plate 20 of the battery mounting structure 10 can reuse the existing structure of the vehicle body, thereby reducing costs while ensuring that the battery mounting structure 10 still has sufficient strength and rigidity.

[0040] The battery 50 is not directly mounted on the bottom plate 20 , but is indirectly mounted on the bottom plate 20 via the tray structure 30 . The tray structure 30 is fixedly connected to the bottom plate 20 , and the tray structure 30 carries the battery 50 .

[0041] The double-layer structure of the tray structure 30 and the base plate 20 enhances the strength and rigidity of the battery mounting structure 10. At the same time, the fixed connection between the tray and the base plate 20 is more stable than the connection between the battery 50 and the base plate 20, and is less likely to fail in the connection and cause the battery 50 to separate from the base plate 20, or the battery 50 to catch fire or explode due to deformation due to collision.

[0042] The vehicle body assembly 40 ′ is a collection of the frame and shell of the entire vehicle body structure, which may include multiple vehicle body structure components. As a part of the vehicle, the vehicle body assembly 40 ′ provides the required support strength and rigidity for the vehicle as a whole.

[0043] Reusing part of the vehicle body assembly 40 ′ as part of the protective structure 40 can reuse the existing structure of the vehicle body, thereby reducing costs while ensuring that the battery mounting structure 10 still has sufficient strength and rigidity.

[0044] The tray structure 30 is arranged in the protective structure 40, that is, the battery 50 is installed in the protective structure 40 through the tray structure 30. The protective structure 40 can form a ring-shaped enclosed protection. The structural strength is large and the overall rigidity is good in the area enclosed by the protective structure 40. It has a strong protection capability against the collision of the whole vehicle and can provide comprehensive mechanical protection for the battery 50, effectively improving the structural strength and rigidity near the battery 50 arrangement area.

[0045] See also Figure 1In some embodiments, the partial vehicle body assembly 40' reused as the protective structure 40 includes a vehicle side panel assembly 41', a portion of the vehicle longitudinal beam structure 21' is reused as the protective structure 40, the vehicle longitudinal beam structure 21' is fixedly disposed on the vehicle rear floor 20', and the vehicle side panel assembly 41' and a portion of the vehicle longitudinal beam structure 21' are enclosed to form the protective structure 40.

[0046] In these embodiments, the protective structure 40 is formed by enclosing a vehicle side panel assembly 41' in a vehicle body assembly 40' of an existing vehicle body structure and a portion of a vehicle longitudinal beam structure 21' in a vehicle rear floor 20', thereby reducing costs while ensuring that the battery mounting structure 10 still has sufficient strength and rigidity.

[0047] The vehicle side assembly 41' is an important structure that forms the left and right side walls of the vehicle and constitutes the cabin. The vehicle side assembly 41' is a side surface component that supports the top cover and connects the front and rear parts of the vehicle body. It is a load-bearing frame that ensures the safety of the vehicle body against side impacts and has great rigidity and strength in resisting bending and torsion.

[0048] A vehicle longitudinal beam structure 21' is formed on the vehicle rear floor 20' by means of sheet metal or pressing. The vehicle longitudinal beam structure 21' is directly formed by deforming the steel bottom plate 20 in the vehicle rear floor 20', so the vehicle longitudinal beam structure 21' also has high rigidity and strength.

[0049] See also Figure 1 In some embodiments, the vehicle side enclosure assembly 41 ′ reused as the protective structure 40 includes a vehicle rear apron 411 ′ and a vehicle wheelhouse beam 412 ′. The vehicle rear apron 411 ′, the vehicle wheelhouse beam 412 ′ and the vehicle longitudinal beam structure 21 ′ together form the protective structure 40 .

[0050] In these embodiments, the vehicle rear apron 411 ′ and the vehicle wheel arch beam 412 ′ in the vehicle side assembly 41 ′ of the existing vehicle body structure are used to enclose and form the protective structure 40 , thereby reducing costs while ensuring that the battery mounting structure 10 still has sufficient strength and rigidity.

[0051] The vehicle rear apron 411 ′ is a collection of a part of the side surface and a part of the rear enclosure structure of the vehicle body, and the vehicle rear apron 411 ′ also has great rigidity and strength in resisting bending and torsion.

[0052] The vehicle wheel cover beam 412' is a partial structure of the vehicle wheel cover assembly, which provides positioning and accommodation space for the four wheels of the vehicle. The vehicle wheel cover beam 412' also has great rigidity and strength in resisting bending and torsional motion.

[0053] The vehicle rear apron 411 ′ and the vehicle wheelhouse beam 412 ′ cooperate to form an annular structure with three sides enclosed and one side open. The longitudinal beam structure on the vehicle rear floor 20 ′ is arranged at the opening to enclose and form a protective structure 40 .

[0054] See also Figure 1 In some embodiments, the vehicle rear apron 411' reused as the protective structure 40 includes a vehicle side panel 4111' and a vehicle rear panel 4112', and the vehicle rear panel 4112', the vehicle side panel 4111', the vehicle wheel arch beam 412' and the vehicle longitudinal beam structure 21' together form the protective structure 40.

[0055] In these embodiments, the vehicle side panels 4111 ′ and the vehicle rear panel 4112 ′ in the vehicle rear apron 411 ′ of the existing vehicle body structure are used to enclose and form the protection structure 40 , thereby reducing costs while ensuring that the battery mounting structure 10 still has sufficient strength and rigidity.

[0056] The vehicle side panels 4111 ′ and the vehicle rear panel 4112 ′ are part of the vehicle rear apron 411 ′, and also have great rigidity and strength in resisting bending and torsion.

[0057] The vehicle side panel 4111 ′ forms a structure of the protection structure 40 close to the side of the vehicle body, and the vehicle rear panel 4112 ′ forms a structure of the protection structure 40 close to the rear side of the vehicle body.

[0066] In these embodiments, the connecting ribs 52 are connected to the tray structure 30 by bolts 31 while clamping the limiting portion 51, thereby ensuring a fixed connection effect and facilitating installation, maintenance and disassembly.

[0067] The two limiting portions 51 arranged at two opposite sides along the first direction X are both provided with connecting ribs 52 , and the connecting ribs 52 are connected to the tray structure 30 by two M6 bolts 31 with a diameter of 6 mm, and the connection is firm.

[0068] The cross-sectional shape of the connecting rib 52 in the first direction X is Z-shaped.
