[0026] ​​In order to have a clearer understanding of the technical features, objectives and effects of the utility model, the specific implementation manners of the utility model will be described with reference to the drawings, and the same reference numerals in the drawings represent the same or similar components with the same function.

[0027] In this document, "illustrative" means "serving as an example, instance, or illustration," and should not necessarily be construed as preferred or advantageous over other implementations.

[0028] Figure 1 Structure schematic view of a illustrative implementation manner of the automobile battery pack protection support. Figure 2 For Figure 1 Structure schematic view of the installation position of the battery pack protection support. As Figure 1 and Figure 2 The automobile battery pack protection support includes a guide member 10 and a crash member 20. In this illustrative implementation manner, the guide member 10 and the crash member 20 are integrally formed to ensure the strength of the protection support.

[0029] Specifically, the guide member 10 is fixedly arranged on the automobile chassis 40, and the guide member 10 is arranged on the side of the battery pack 30 facing the tail of the automobile in the length direction of the automobile, as Figure 2 The guide member 10 and the battery pack 30 leave a space therebetween, thereby forming a buffer zone to reduce the damage to the battery pack 30. Meanwhile, the crash member 20 is connected to the guide member 10 and laid on the top of the battery pack 30. The guide member 10 guides the impact object (such as the external spare tire of the off-road vehicle) moving towards the top of the battery pack 30, and the crash member 20 guides the impact object moving towards the top of the battery pack 30 to move towards the head of the automobile to prevent the impact on the battery pack, thereby ensuring the safety of the battery and reducing the cost effectively due to the simple structure.

[0030] As Figure 1 The guide member 10 includes a base 16 and a guide portion 18. In this illustrative implementation manner, the base 16 is in the form of a flat plate and is fixedly connected to the automobile chassis by bolts to ensure the stability of the protection support. The guide portion 18 is connected to one end of the base 16, and the guide portion 18 has a first guide surface 11. The distance of the first guide surface 11 from the automobile chassis 40 gradually increases in the length direction of the automobile to guide the impact object moving towards the battery pack 30 in the length direction of the automobile to gradually move upwards of the battery pack 30. Specifically, in this illustrative implementation manner, the first guide surface 11 is in the form of a cylindrical surface, thereby effectively guiding the impact object to move upwards of the battery pack 30 and reducing the impact energy. In other illustrative implementation manners, the first guide surface 11 can also be a smooth inclined surface.

[0031] As Figure 1 andFigure 2 As shown in the figure, the anti-collision member 20 is in the form of a flat plate. The anti-collision member 20 is connected to the guide member 10 and is laid on the top of the battery pack. The anti-collision member 20 has a second guide surface 21 which is parallel to the battery pack 30 and is connected to the first guide surface 11 to guide the impact object to move towards the front of the vehicle, thereby further reducing the damage to the battery pack 30.

[0032] Figure 3 For Figure 1 The rear view structure of the battery pack protection bracket is shown in the figure. As Figure 3 As shown in the figure, the guide member 10 further comprises five reinforcing members 12, each of which is in the form of a flat plate perpendicular to the width direction of the vehicle and is connected to the back of the guide part 18 and the base 16. The five reinforcing members 12 are evenly arranged along the width direction of the vehicle, thereby enhancing the strength of the protection bracket. The bottom of the reinforcing member 12 extends along the width direction of the vehicle to form a support part 121 which is connected to the chassis of the vehicle to ensure sufficient stability of the protection bracket.
