[0002] Currently, hybrid vehicles are quite common, and battery mounting racks are typically used to install the batteries to meet the installation requirements. Specifically, in the process of arranging the power batteries in minibuses, top-mounted or rear-mounted layouts are commonly used. However, due to the large weight of the power batteries, a top-mounted layout increases the vehicle's size, affecting aesthetics, and also raises the vehicle's center of gravity, impacting stability. A rear-mounted layout leads to an unbalanced weight distribution between the front and rear axles, resulting in a heavier rear axle. Therefore, how to install battery mounting racks at the bottom of the mid-section frame of minibuses has become a pressing issue. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a power battery mounting frame, which is spliced ​​together by a first mounting beam, a second mounting beam, a bracket, and a third mounting beam.

[0028] See Figures 1 to 5 A power battery mounting bracket includes: a first mounting beam 100, a second mounting beam 200, and a third mounting beam 300. The first mounting beam 100 is used to mount to a vehicle frame 110 and has a first waist-shaped hole 101 in the left-right direction. The second mounting beam 200 has a second waist-shaped hole in the front-back direction. A bracket 210 is connected between the first mounting beam 100 and the second mounting beam 200. The bracket 210 is used to mount a power battery and has a first mounting hole at one end. The first mounting hole is connected to the first waist-shaped hole 101 by a first bolt assembly. The third mounting beam 300 has a second mounting hole, which is connected to the second waist-shaped hole by a second bolt assembly 310.

[0029] During installation, the power battery mounting bracket with the above structure is installed by first mounting the first mounting beam 100 to one side bar of the frame 110, then mounting the third mounting beam 300 to the other side bar of the frame 110. Next, the front and rear positions of the second mounting beam are adjusted, and the second mounting beam 300 is installed into the corresponding second mounting hole and second waist-shaped hole using the second bolt assembly 310. Finally, the bracket 210 is placed above the first support beam 211 and the second support beam 212. The left and right positions of the bracket 210 are adjusted, and one side of the bracket 210 is connected to the second mounting beam 200. The other side of the bracket 210 is installed into the corresponding first mounting hole and first waist-shaped hole 101 using the first bolt assembly. This completes the adjustable installation of the entire bracket onto the frame 110, which facilitates the subsequent installation of the power battery using the bracket 210, thus avoiding problems caused to the vehicle by using a top-mounted or rear-mounted installation method for the power battery.

[0030] Understandably, the first bolt assembly and the second bolt assembly 310 include bolts with hexagonal flange faces, bolt threads that engage with nuts, thereby connecting the corresponding two components through the engagement of the bolt and nut, which also facilitates the assembly and disassembly of the entire frame.

[0031] See Figures 1 to 5Furthermore, the bracket 210 includes multiple parallel first support beams 211 connected to the first mounting beam 100 and the second mounting beam 200. Multiple second support beams 212 are spaced apart along the length of each first support beam 211, and the first and second support beams 211 are perpendicularly connected. Specifically, the first and second support beams 211 and 212 form a crisscross structure, which is beneficial for evenly distributing the weight of the power battery. It is understood that the length of the first support beam 211 is greater than the length of the second support beam 212, which is beneficial for forming a long, narrow bracket 210 to evenly transmit the stress of the rear leaf spring seat of the frame 110, thus improving stress concentration in the leaf spring seat. The first and second support beams 211 and 212 are fixed together by welding, thereby improving the structural strength of the bracket 210.

[0032] See Figures 1 to 5 Furthermore, the first mounting beam 100 has a plurality of first waist-shaped holes 101 spaced apart along its length direction, and each first support beam 211 has a first mounting hole at one end. The plurality of first waist-shaped holes 101 and the first mounting holes are arranged in a one-to-one correspondence, thereby increasing the connection points between the bracket 210 and the first mounting beam 100, which is beneficial to improving the stability of the bracket 210 and the first mounting beam 100.

[0033] See Figures 1 to 5 Furthermore, the first mounting beam 100 has a U-shaped structure and includes two opposing first horizontal plates 102. A first vertical plate 103 connects the two first horizontal plates 102, and the first vertical plate 103 is connected to the frame 110 by a third bolt assembly. A first waist-shaped hole 101 is provided through the two first horizontal plates 102, and a first support beam 211 is located between the two first horizontal plates 102. Specifically, after the first mounting beam 100 and the second mounting beam 200 are fixed, the first support beam 211 is first erected above the lower first horizontal plate 102 and the second mounting beam 200. Then, the position of the first support beam 211 is adjusted, and one end of the first support beam 211 is connected to the second support beam 212. Finally, the other end of the first support beam 211 is connected between the two first horizontal plates 102 by a first bolt assembly. Understandably, the first mounting beam 100 is an integral structure formed by bending steel plates, which on the one hand facilitates the stable installation of the first mounting beam 100, and on the other hand helps to increase the bending strength of the first mounting beam 100.

[0034] See Figures 1 to 5Furthermore, the second mounting beam 200 has a Z-shaped structure and includes a second vertical plate 201. Second horizontal plates 202 are vertically connected to the upper and lower sides of the second vertical plate 201, respectively. The lower second horizontal plate 202 connects to the first support beam 211, and the upper second horizontal plate 202 connects to the third mounting beam 300. Specifically, the lower second horizontal plate 202 supports the first support beam 211, facilitating its installation on the second mounting beam 200. The upper second horizontal plate 202 forms a plane for the installation of the second bolt assembly 310, facilitating the installation of the second support beam 212 and the third mounting beam 300. It is understood that the integrated structure of the second mounting beam 200, achieved through bending steel plates, improves its structural strength.

[0035] See Figures 1 to 5 Furthermore, the second waist-shaped hole is opened in the second horizontal plate 202 located on the upper side, so as to facilitate the adjustment of the installation position of the second horizontal plate 202 and the third mounting beam 300 through the second waist-shaped hole, thereby avoiding the situation where the hole position of the third mounting beam 300 does not match the second mounting beam 200 after the third mounting beam 300 is fixed.

[0036] See Figures 1 to 5 Furthermore, the third mounting beam 300 has an L-shaped structure and includes a third horizontal plate 301 and a third vertical plate 302 that are perpendicularly connected to each other. The third horizontal plate 301 is connected to the upper second horizontal plate 202 via a second bolt assembly 310. The third vertical plate 302 has a first through hole 303 for connecting to the frame 110. Specifically, during installation, the first through hole 303 is first bolted to the frame 110, which facilitates the installation of the third vertical plate 302 onto the frame 110. Then, the position of the upper second horizontal plate 202 is adjusted, and finally, the second horizontal plate 202 and the third horizontal plate 301 are connected using the second bolt assembly 310.

[0037] See Figures 1 to 5 Furthermore, reinforcing ribs 400 are provided between the second vertical plate 201 and the upper second horizontal plate 202, and between the third horizontal plate 301 and the third vertical plate 302. This enhances the structural strength of the second mounting beam 200 and the third mounting beam 300, thereby reducing the bending strength of the second mounting beam 200 and the third mounting beam 300. It is understood that multiple reinforcing ribs 400 are provided, and these multiple reinforcing ribs 400 are spaced apart along the front-rear direction on the second mounting beam 200 or the third mounting beam 300.

[0038] See Figures 1 to 5 Furthermore, the first support beam 211 is provided with a plurality of second through holes 213 along its length direction. The second through holes 213 are used to install the power battery, thereby facilitating the provision of holes for installing the power battery.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
