[0018] A fast-swap battery pack mounting bracket for automobiles includes two crossbeams 1 on both sides, and a longitudinal beam is installed between the two crossbeams 1.

[0019] The longitudinal beams include a first longitudinal beam 4, a second longitudinal beam 8, a third longitudinal beam 9, and a fourth longitudinal beam 10, arranged sequentially from front to back. The first longitudinal beam 4 is located at the front end between the two side crossbeams 1, and its two ends are connected to the two side crossbeams 1 by two diagonal beams 5 respectively. In this invention, the two side crossbeams 1, the first longitudinal beam 4, the second longitudinal beam 8, the third longitudinal beam 9, the fourth longitudinal beam 10, and the two side diagonal beams 5 together form a frame structure. This frame structure is simple and is fixed by welding, resulting in a strong connection.

[0020] The two crossbeams 1 on both sides are each provided with a hollow cavity, and the bottom surface of the crossbeam 1 is provided with multiple transverse battery pack connection points spaced apart along its length. In this invention, the two crossbeams 1 on both sides are connected to a quick-change battery pack through these multiple transverse battery pack connection points. The bottom surface of the crossbeam 1 in this invention has four transverse battery pack connection points spaced apart along its length. Each horizontal battery pack connection point is provided with a first elongated hole 2 that connects to the hollow cavity of the crossbeam 1. In application, the battery pack is connected to the horizontal battery pack connection point by a T-shaped screw. When connecting, the T-shaped head of the T-shaped screw is inserted into the first elongated hole 2 and the inner cavity of the crossbeam 1 and rotated 90 degrees.

[0021] Each of the aforementioned transverse battery pack connection points includes a first reinforcing plate 13, on which a first elongated hole 2 is formed. First ear plates 14 are connected to both sides of the first reinforcing plate 13. The crossbeam 1 is located between the two first ear plates 14, and the two first ear plates 14 are respectively connected to the crossbeam 1. The first ear plates 14 are riveted to the crossbeam 1. This invention enhances the strength of the transverse battery pack connection points by providing the first reinforcing plate 13, which is integrally formed with the two first ear plates 14.

[0022] At least two lower connecting blocks 11 are installed at the bottom of the first longitudinal beam 4. The lower connecting block 11 has an inner cavity and a longitudinal battery pack connection point is provided on the bottom surface of the lower connecting block 11. The two lower connecting blocks 11 in this utility model are respectively connected to the quick-change battery pack through the longitudinal battery pack connection point.

[0023] Each longitudinal battery pack connection point is provided with a second elongated hole 12 that connects to the hollow cavity of the lower connecting block 11. In application, the battery pack is connected to the longitudinal battery pack connection point via a T-screw. During connection, the T-head of the T-screw is inserted into the second elongated hole 12 and the inner cavity of the lower connecting block 11 and rotated 90 degrees.

[0024] Each of the longitudinal battery pack connection points includes a second reinforcing plate 15, on which a second elongated hole 12 is formed. Second ear plates 16 are connected to both sides of the second reinforcing plate 15. A lower connecting block 11 is located between the two second ear plates 16, and the two second ear plates 16 are connected to the lower connecting block 11. The second ear plates 16 and the lower connecting block 11 are riveted together. This invention enhances the strength of the longitudinal battery pack connection points by providing the second reinforcing plate 15, which is integrally formed with the two second ear plates 16.

[0025] The top surface of the longitudinal beam is provided with a bracket mounting hole 3, and an upper connecting block 6 is installed on each of the two inclined beams 5. The upper connecting block 6 is provided with a bracket mounting hole 3. The height of the top surface of the upper connecting block 6 is flush with the top surface of the first longitudinal beam 4. The bracket mounting hole 3 is a countersunk hole. By setting the bracket mounting hole 3 as a countersunk hole, the bolt head can be inserted into the countersunk hole when connecting to the vehicle body with bolts.

This utility model achieves positioning with the vehicle body through the positioning pins 7 on the first longitudinal beam 4 and the positioning pins 7 on the second longitudinal beam 8, thereby making the installation of this utility model more convenient.

[0028] When modifying a car, we only need to make multiple body fixing holes corresponding to multiple bracket mounting holes 3 and body positioning holes corresponding to positioning pins 7 on the car body. During installation, first insert multiple positioning pins 7 into the body positioning holes on the car body, and then connect the bracket mounting holes 3 and the body fixing holes respectively with bolts and nuts.
