According to the battery mounting bracket, under the normal use condition of a vehicle, the upper frame body 1 and the lower frame body 2 are fixed by the connecting frame 3, and the space between the upper frame body 1 and the lower frame body 2 is the battery mounting space. When the vehicle is subjected to a strong collision, resulting in deformation of the vehicle body floor or a beam structure associated with the vehicle body floor, the weakened portion 3-3 at the junction of the connecting frame 3 and the mounting frame 1-1 may be broken first. After the fracture, the limit posts 3-2 in the arch-shaped mounting grooves 1-3 are used as new connecting pieces for connecting the upper frame body 1 and the lower frame body 2. Due to the inertia effect in the collision process, the lower frame body 2 and the battery positioned in the lower frame body will move forwards or backwards, the arched mounting grooves 1-3 limit the movement track of the lower frame body 2, so that the lower frame body can displace downwards in the forward or backward movement process, the distance between the battery and the vehicle body floor can be increased, a deformation space is reserved, and the battery is prevented from being damaged when the vehicle body floor or a beam structure related to the vehicle body floor is deformed. When the frame body 3-1 is fixed relative to the mounting frame 1-1 and the bottom frame 2-1, the limit post 3-2 is required to be positioned at the highest point of the arched mounting groove 1-3, so that the battery can move downwards no matter the movement direction of the lower frame body 2 is forward or backward after the weakened portion 3-3 is subjected to collision fracture.
The bottom surface of the upper mounting plate 1-2 is a horizontal plane, the top surface of the lower mounting plate 2-2 is a horizontal plane, the mounted battery mounting bracket is arranged on the bottom surface of the upper mounting plate 1-2 opposite to the top surface of the lower mounting plate 2-2, the distance is between 0.2 cm and 0.5cm, the displacement of the lower frame body 2 is limited, the breaking moment of the weakened part 3-3 is avoided, and the lower frame body 2 deflects relative to the upper frame body 1.
In order to ensure smooth displacement of the lower frame body 2, the movement paths of the four limit posts 3-2 are required to be as consistent as possible, so that path interference is avoided, and the lower frame body 2 is prevented from moving and being blocked, so that the outlines of the four arch-shaped mounting grooves 1-3 are required to be as consistent as possible.
According to the mounting bracket structure, the weakened portions 3-3 are broken in the collision process, the battery moves downwards, the battery is protected, and in the subsequent maintenance process, the connecting frame 3 is only required to be replaced or welded again, so that the maintenance cost is reduced.
