Description

Technical Field

[0001] This utility model relates to the field of vehicle structure technology, specifically to a vehicle battery fixing structure and a vehicle. Background Technology

[0002] With the rapid development of the new energy vehicle industry, vehicle safety has become a primary goal in automotive development. Batteries are essential for basic functions such as door unlocking, instrument panel operation, and engine starting, ensuring the normal and stable operation of the vehicle's electrical equipment. They are an indispensable component of the low-voltage system in new energy vehicles. As the power consumption of vehicles increases, the capacity and size of batteries will also increase accordingly.

[0003] Existing automotive batteries are typically mounted in the front engine compartment using methods such as mounting. However, large-capacity and bulky batteries occupy considerable space. Due to space constraints within the vehicle and the size and weight of the batteries themselves, this type of mounting structure and method not only has low space utilization but also limited load-bearing capacity and poor connection stability. The battery is prone to detaching from its mounting structure during crash tests, leading to battery damage and posing a safety risk to passengers. Utility Model Content

[0004] In view of the above problems, this utility model provides a vehicle battery fixing structure and vehicle, which can effectively improve the connection stability between the battery and its fixing structure.

[0005] According to one aspect of the present invention, a vehicle battery fixing structure is provided, comprising: a mounting plate having a first mounting surface and a second mounting surface opposite to each other along the height direction on its outer surface; the first mounting surface being adapted to support a battery and the second mounting surface being adapted to be fixedly connected to the vehicle floor; two sets of first limiting components spaced apart along a first direction on the first mounting surface, adapted to abut against opposite sides of the battery distributed along the first direction; and two sets of second limiting components spaced apart along a second direction on the first mounting surface, adapted to abut against opposite sides of the battery distributed along the second direction, wherein one set of second limiting components is detachably fixedly connected to the mounting plate; wherein the height direction, the first direction, and the second direction are perpendicular to each other; overlapping surfaces with the normal direction upward along the height direction are formed at the bottom of the two sides of the battery distributed along the second direction, and retaining edges are formed on the opposite inner sides of the two sets of second limiting components along the second direction, the retaining edges being adapted to press against the overlapping surfaces to fix the battery on the first mounting surface.

[0006] In an exemplary embodiment of the present invention, the bottom sides of the battery distributed along the second direction extend outward to form a raised edge, and the overlapping surface is defined on the upper end surface of the raised edge; or the bottom sides of the battery distributed along the second direction are recessed inward to form a groove, and the overlapping surface is defined on the lower end surface of the groove.

[0007] In an exemplary embodiment of the present invention, one set of first limiting components includes a plurality of limiting blocks, which are spaced apart along a second direction; wherein, the side of the limiting block near another set of first limiting components defines a limiting surface suitable for fitting against the side of the battery.

[0008] In an exemplary embodiment of the present invention, the other set of first limiting components is a wedge-shaped platform, which has a wedge-shaped surface extending forward in a first direction and upward in a height direction. The wedge-shaped surface is adapted to support the bottom surface of the battery on the side away from the other set of first limiting components.

[0009] In an exemplary embodiment of the present invention, the mounting plate has at least one hollow area in the middle, and the hollow area is arranged through the height direction.

[0010] In an exemplary embodiment of the present invention, a plurality of support frames are provided around the mounting plate, and the support frames are recessed downward from the first mounting surface along the height direction; the second mounting surface is defined at the lower end surface of the support frame.

[0013] In an exemplary embodiment of the present invention, the buffer plate has a shock-absorbing pad on the side of the plate near the first limiting component.

[0014] According to a second aspect of the present invention, a vehicle is provided, including the above-described vehicle battery mounting structure.

[0015] This invention enables effective support and fixation of the battery to the vehicle floor via a mounting plate. Two sets of first limiting components provide horizontal x-axis restraint, and two sets of second limiting components provide horizontal y-axis restraint.

[0040] like Figures 1 to 6 As shown, this embodiment provides a vehicle battery fixing structure, including: a mounting plate 1, two sets of first limiting components 2 / 2' and two sets of second limiting components 3 / 3'; the outer surface of the mounting plate 1 has a first mounting surface 11 and a second mounting surface 12 opposite to each other along the height direction z, the first mounting surface 11 is suitable for supporting the battery 8, and the second mounting surface 12 is suitable for fixed connection with the vehicle floor 10, the fixed connection method including but not limited to welding, bolt connection, etc.; the two sets of first limiting components 2 / 2' are spaced apart along the first direction x on the first mounting surface 11, and the two sets of second limiting components 3 / 3' are spaced apart along the second direction y on the first mounting surface 11, and one set of second limiting components 3' is perpendicular to the mounting plate. 1. The battery is detachably fixed. At this time, the two sets of first limiting components 2 / 2' and the two sets of second limiting components 3 / 3' form an installation space for placing the battery 8. At the same time, the bottom sides of the battery 8 distributed along the second direction y have overlapping surfaces 811 with the normal direction z pointing upward. The two sets of second limiting components 3 / 3' have baffles 31 on their opposite inner sides along the second direction y. The baffles 31 and the first mounting surface 11 form an accommodating space. The bottom sides of the battery 8 distributed along the second direction y can be inserted into the accommodating space between the baffles 31 and the first mounting surface 11, so that the baffles 31 are pressed against the overlapping surfaces 811 to fix the battery 8 to the first mounting surface 11.

[0041] After placing the battery 8 on the first mounting surface 11, the opposite sides of the battery 8 distributed along the first direction x abut against the two sets of first limiting components 2 / 2', limiting the battery 8 in the first direction x. Then, the battery 8 is pushed along the second direction y, so that one side of the battery 8 distributed along the second direction y abuts against the inner side of the second limiting component 3 on that side. At this time, the overlapping surface 811 of the bottom of the battery 8 on that side is pressed against the first mounting surface 11 by the flange 31 of the second limiting component 3 on that side. Then, a set of detachable second limiting components 3' is fixed to the other side of the battery 8 distributed along the second direction y. At this time, the opposite sides of the battery 8 distributed along the second direction y abut against the two sets of second limiting components 3 / 3', limiting the battery 8 in the second direction y, and the flange 31 of the detachable set of second limiting components 3' is pressed against the overlapping surface 811 of the battery 8 on the other side of the battery 8 distributed along the second direction y, so as to fix the battery 8 on the first mounting surface 11. Thus, the battery 8 is positioned and fixed in six directions through the mounting plate 1, the first limiting component 2 / 2' and the second limiting component 3 / 3', which can effectively improve the connection stability between the battery 8 and the mounting plate 1 and make it less likely for the two to fall off.

[0042] It is understood that in this embodiment, the first direction x can be the vehicle length direction, and the second direction y can be the vehicle width direction. These two directions need to be perpendicular to each other on the horizontal plane, and there are no restrictions here. The normal of the aforementioned overlapping surface 811 is set upward along the height direction z. It can be set vertically upward along the height direction z, or it can be set upward along the height direction z and tilted outward along the second direction y. This allows the retaining edge 31 of the second limiting component 3 / 3' to press against the overlapping surface 811, restricting the movement of the battery 8 along the height direction z. Further details are omitted here.

[0043] Specifically, such as Figure 5 and Figure 6As shown, in this embodiment, the normal direction of the overlapping surface 811 of the battery 8 is upward along the height direction z and outward along the second direction y. In this embodiment, the second limiting component 3, located on the first mounting surface 11, extends upward along the height direction z and bends inward along the second direction y at one end facing the battery 8 to form a retaining edge 31 suitable for fastening onto the overlapping surface 811. A detachably connected set of second limiting components 3' is generally arc-shaped, with one end along the second direction y away from the battery 8 abutting against the first mounting surface 11. The second limiting component 3' and the mounting plate 1 are in the first... Bolt connection holes are correspondingly provided on the mounting surface 11, and the two are fixed together by bolt assembly to realize the detachable fixed connection between the second limiting component 3' and the mounting plate 1; the end of the component close to the battery 8 along the second direction y extends upward along the height direction z and bends inward along the second direction y to form a retaining edge 31 suitable for pressing on the overlapping surface 811, and when the second limiting component 3' is fixedly connected to the mounting plate 1, it is pressed on the overlapping surface 811 of the battery 8, thereby fixing the battery 8 to the first mounting surface 11 and realizing the limiting of the battery 8 in the height direction z and the second direction y.

[0044] In some embodiments, such as Figure 5 and Figure 6 As shown, the bottom sides of the battery 8 distributed along the second direction y extend outward to form a protruding edge 81. At this time, the overlapping surface 811 is limited to the upper end surface of the protruding edge 81. After the battery 8 is placed on the first mounting surface 11, the protruding edge 81 can be embedded between the retaining edge 31 and the first mounting surface 11, completing the pressing of the retaining edge 31 on the overlapping surface 811, thereby limiting and fixing the battery 8 in the height direction z.

[0045] Similarly, in other embodiments, grooves (not shown) can be formed inwardly on the bottom sides of the battery 8 distributed along the second direction y. In this case, the overlapping surface 811 is limited to the lower end surface of the groove. After the battery 8 is placed on the first mounting surface 11, the retaining edge 31 can extend into the groove and press against the overlapping surface 811. At this time, the structure of the lower part of the groove is limited between the retaining edge 31 and the first mounting surface 11, thereby realizing the limiting and fixing of the battery 8 in the height direction z.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, one set of first limiting components 2 includes multiple limiting blocks 21, which are distributed at intervals along the second direction y. The limiting block 21 has a limiting surface 211 on the side of the limiting block 21 closest to another set of first limiting components 2', which is suitable for fitting against the side of the battery 8. In this way, while ensuring the effectiveness of the limiting in the first direction x, the space occupied and material usage of the first limiting components 2 can be reduced, and the weight reduction can be achieved.

[0047] Specifically, such as Figure 3 and Figure 4 As shown, there are four limiting blocks 21 in this embodiment, all of which are designed as T-shaped platforms. They have a certain height in the height direction z, a certain length in the first direction x, and a certain width in the second direction y, thus having sufficient structural strength to effectively limit and support the battery 8 in the first direction x.

[0048] In some embodiments, such as Figure 3 and Figure 4 As shown, another set of first limiting components 2' is a wedge-shaped platform 22. The wedge-shaped platform 22 has a wedge-shaped surface 221 extending forward in the first direction x and upward in the height direction z. The wedge-shaped surface 221 is adapted to support the bottom surface of the battery 8 on the side away from the other set of first limiting components 2. By setting the wedge-shaped platform 22, interference with the installation and removal process of the battery 8 can be avoided while ensuring the effectiveness of the limiting in the first direction x, thereby improving the convenience of installing and removing the battery 8.

[0049] Understandably, due to the inclined arrangement of the wedge surface 221, when the bottom surface of the battery 8 near the wedge platform 22 wants to move along the first direction x, it must simultaneously move along the height direction z. However, due to the limiting effect of the second limiting component 3 / 3' on the battery 8 in the height direction z, the battery 8 cannot move in the height direction z. Therefore, the bottom surface of the battery 8 near the wedge platform 22 cannot move along the first direction x on the wedge surface 221, thus effectively limiting and supporting the battery 8 in the first direction x.

[0050] Preferably, based on the vehicle's driving direction, a set of first limiting components 2 composed of limiting blocks 21 can be set on the rear side distributed along the first direction x, and another set of first limiting components 2' composed of wedge-shaped platforms 22 can be set on the front side distributed along the first direction x, so as to improve the limiting stability of the battery 8.

[0051] In some embodiments, such as Figure 3 As shown, the mounting plate 1 has at least one hollow area 13 in the middle, and the hollow area 13 is arranged through the height direction z. In this way, on the one hand, the amount of material used in the vehicle battery fixing structure can be further reduced, so as to achieve the purpose of weight reduction; on the other hand, it is conducive to heat dissipation at the bottom of the battery 8.

[0052] In some embodiments, such as Figure 7As shown, the mounting plate 1 is provided with multiple support frames 4 around its perimeter. The support frames 4 are recessed downwards from the first mounting surface 11 along the height direction z. In this way, the support frames 4 and the mounting plate 1 can be integrally set, and multiple interconnected sidewalls can be formed at the recessed area to improve the support strength and stability of the support frames 4. At the same time, the second mounting surface 12 is defined at the lower end surface of the support frame 4. Based on the height setting of the support frame 4, the first mounting surface 11 and the vehicle floor 10 below are spaced apart, which allows the hollow area 13 to be connected to the outside through the spaced area, further improving the bottom heat dissipation performance of the battery 8.

[0053] In some embodiments, such as Figure 7 and Figure 8 As shown, the second mounting surface 12 has a connecting hole 121 that extends along the height direction z. Fasteners 9 pass through the connecting hole 121 and are fixedly connected to the vehicle floor 10 to fix the support frame 4 to the vehicle floor 10. A shock-absorbing pad 5 is provided between the second mounting surface 12 and the vehicle floor 10. The shock-absorbing pad 5 can be a rubber shock-absorbing pad. This can further reduce the vibration transmission between the mounting plate 1 and the vehicle floor, avoid abnormal noise caused by the hard connection between the mounting plate 1 and the rear floor during vehicle operation, and improve the NVH performance of the whole vehicle.

[0054] It is understood that the fastener 9 can be a bolt 91, with a through hole made on the vehicle floor 10 corresponding to the connecting hole 121, and a projection weld nut 92 welded below the through hole on the vehicle floor 10. The bolt is then passed through the connecting hole 121 on the second mounting surface 12, the shock-absorbing pad 5, and the through hole on the vehicle floor 10 in sequence, and threadedly connected to the projection weld nut 92 below the vehicle floor 10, thereby achieving a fixed connection between the support frame 4 and the vehicle floor 10.

[0055] It is understandable that, apart from the detachable second limiting component 3', the mounting plate 1, the two first limiting components 2 / 2', the other second limiting component 3, and the multiple support frames 4 in the above embodiment can be integrally formed by die casting using aluminum alloy material, so that the mounting plate 1, the first limiting component 2 / 2', one of the second limiting components 3, and the support frames 4 are formed into a whole, reducing the setting of connecting parts, improving the integration and structural strength of the mounting plate 1, and further meeting the lightweight requirements of the mounting plate 1.

[0056] In some embodiments, such as Figure 1 and Figure 2As shown, the vehicle battery fixing structure also includes a buffer plate 6, which is located on the side of the first limiting component 2 away from the battery 8. The bottom of the buffer plate 6 is fixedly connected to the first mounting surface 11, and the normal direction of the buffer plate 6 is parallel to the first direction x. The buffer plate 6 serves as a second layer of protection to limit and protect the battery 8, preventing it from falling off the mounting plate 1. Simultaneously, the buffer plate 6 is also compatible with the power distribution box mounting frame, reducing unnecessary space occupation.

[0057] Specifically, in this embodiment, the two ends of the bottom of the buffer plate 6, distributed along the second direction y, extend along the first direction x towards the side closer to the battery 8, thereby forming a C-shaped connecting part. The C-shaped connecting part is fixedly connected to the first mounting surface 11. The connection method includes, but is not limited to, welding, bolt connection, etc., which can achieve a stable connection of the buffer plate 6 on the mounting plate 1. Preferably, based on the consideration of the vehicle's driving direction, the buffer plate 6 is located on the rear side distributed along the first direction x, which can prevent the battery 8 from falling into the rear compartment during a vehicle collision.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the buffer plate 6 has a shock-absorbing pad 7 on the side of the plate closest to the first limiting component 2. The shock-absorbing pad 7 can be made of materials such as rubber and can be fixed to the side of the buffer plate 6 facing the battery 8 by adhesive, in order to reduce the impact that may occur when the battery 8 collides with the buffer plate 6.

[0059] Preferably, the shock-absorbing pad 7 can be designed to have a certain thickness in the first direction x, so that the shock-absorbing pad 7 is attached to the surface of the buffer plate 6 and the side wall of the battery 8 on both sides of the first direction x, so as to play an effective role in isolation and buffering.

[0061] It is understandable that, such as Figure 9 As shown in the above embodiment and the accompanying drawings, the vehicle battery fixing structure is arranged at the upper left end of the rear floor of the vehicle. This arrangement can effectively save engine compartment space and improve the overall space utilization of the engine compartment, which will not be described in detail here.
