[0041] Reference Figure 1-3 As shown, the battery bracket assembly includes a lower mounting bracket 11, a middle mounting bracket 12 and an upper mounting bracket 13. The lower mounting bracket 11, the middle mounting bracket 12 and the upper mounting bracket 13 together form the battery bracket 10.

[0042] The lower mounting bracket 11 is formed with a plurality of lower mounting areas 111; the middle mounting bracket 12 includes a horizontal support frame 121 and a plurality of legs 122, the horizontal support frame 121 is formed with a plurality of upper mounting areas 123 corresponding to the lower mounting bracket 11, and the plurality of legs 122 are arranged between the plurality of upper mounting areas 123. In this way, batteries can be installed respectively through the lower mounting areas 111 and the upper mounting areas 123.

[0043] The legs 122 include upper columns 1221 and lower columns 1222 located on both sides of the horizontal support frame 121, respectively. The lower columns 1222 are mounted on the lower mounting bracket 11; the upper mounting bracket 13 is mounted on a plurality of upper columns 1221. In this way, by forming a plurality of upper mounting areas 123 on the horizontal support frame 121, and the legs 122 are arranged between adjacent upper mounting areas 123, a modular design between the plurality of upper mounting areas 123 is realized. After the middle mounting bracket 12 is assembled to the lower mounting bracket 11, the installation space for a plurality of upper battery packs can be formed at the same time through one assembly, thereby improving the installation efficiency and assembly process of the battery bracket assembly.

[0044] The horizontal support frames 121 are connected together by the legs 122 to form a whole and then installed on the lower mounting bracket 11 at one time, avoiding the need to install multiple brackets separately, multiple subassembly components and complex assembly procedures.

[0045] Specifically:

[0046] The horizontal support frame 121 includes a plurality of cross beams 1211 and a plurality of longitudinal beams 1212, which are fixed by screw connection, and the support legs 122 are arranged between two of the cross beams 1211, and the two cross beams 1211 are located in adjacent upper installation areas 123. In this way, the longitudinal beams 1212 and cross beams 1211 in each upper installation area 123 are connected to the adjacent support legs 122, and then when the support legs 122 are installed with the lower installation bracket 11, the horizontal support frame 121 can be installed synchronously with the lower installation bracket 11.

[0047] Furthermore, after the support legs 122 are installed with the lower mounting bracket 11, the middle mounting bracket 12 and the lower device bracket form a plurality of lower mounting spaces. Meanwhile, a plurality of support legs 122 and the horizontal support frame 121 form a plurality of upper mounting spaces.

[0048] In this embodiment, the two ends of the cross beam of the upper mounting bracket 13 are respectively buckled on the top of the upper column 1221 and the top of the bracket side 14, so as to ensure the reliability of the connection. At the same time, a flange is provided in the middle of the cross beam of the upper mounting bracket 13, and a connecting beam is provided on the flange, and the cross beams of the upper mounting bracket 13 are connected in sequence through the connecting beam. It should be pointed out that the installation surface where the flange is located is lower than the plane where the cross beam of the upper mounting bracket 13 is located. In this way, it is ensured that when the connecting beam is installed on the cross beam of the upper mounting bracket 13, its height is lower than the top height of the cross beam of the upper mounting bracket 13, thereby reducing the overall height of the battery bracket assembly.

[0049] The battery support assembly further includes a frame 20, which is fixed to the upper column 1221. In this embodiment, the plurality of legs 122 are arranged in two rows and are respectively located on the outer sides of the frame 20 and assembled with the frame 20.

[0050] In this embodiment, the battery support assembly further includes an adjustment gasket 30, and the frame 20 includes a pair of main beams 21 and a secondary beam 22 connecting the pair of main beams 21; the main beam 21 is fixed to the upper column 1221, wherein the main beam 21 and the secondary beam 22 can be integrally formed, so that the overall structural strength of the frame 20 is greater. By arranging the adjustment gasket 30 between the longitudinal beam 1212 and the upper column 1221, the gap between the frame 20 and the upper column 1221 is adjusted to avoid the gap after assembly and cause the overall structure to be unstable.

[0051] In this embodiment, refer to Figure 4 As shown, the battery bracket assembly also includes a bracket 40, which is mounted on the horizontal support frame 121, and the battery is fixed on the bracket 40, for example, the battery can be fixed by screws.

[0052] Specifically, the battery bracket assembly further includes a plurality of first positioning pins 50, which are mounted on the horizontal support frame 121, and the bracket 40 is provided with positioning holes 41 that cooperate with the first positioning pins 50 in the vertical direction. In this way, the accuracy of the installation position of the battery bracket 40 is ensured, thereby also improving the installation position of the battery fixed on the battery bracket 40.

[0053] In one embodiment, referring to Figure 6-7 As shown, the top of the first positioning pin 50 is conical, so that when the positioning hole 41 in the battery bracket 40 falls from the top of the first positioning pin 50 and is inserted into the positioning hole 41, it can play a guiding role.

[0054] In addition, the bottom of the first positioning pin 50 is provided with an internal thread; the first positioning pin 50 is detachably connected to the horizontal support frame 121 through the internal thread hole 51, and the battery bracket 40 can be further fixed by, for example, a bolt and the internal thread hole 51. In this way, compared with fixing the battery bracket 40 to the horizontal support frame 121 by integral molding, welding, etc., the detachable connection of the present application has universality and interchangeability.

[0055] Considering how to facilitate the transfer and installation of the bracket 40 and the battery as a whole onto the horizontal support frame 121 after the battery is installed on the bracket 40, in this embodiment, a hanging point 42 is provided on the side of the bracket 40, and the hanging point 42 is symmetrically arranged about the bracket 40, so that the bracket 40 can be hoisted through the hanging point 42.

[0056] In this embodiment, a limiting hole 1223 is provided at the bottom of the support leg 122, and a second positioning pin 60 adapted to the limiting hole 1223 is provided at the top of the lower mounting bracket 11; thus, the accuracy of the installation of the support leg 122 is improved.

[0057] Reference Figure 5 As shown, the support leg 122 is limited by abutting against the positioning hole 41, and then installed and fixed by screws, with high assembly accuracy. In this embodiment, the second positioning pin 60 is movably connected to the lower mounting bracket 11, so that the position of the second positioning pin 60 can be adjusted according to different installation positions, and the versatility is strong.

[0058] In a feasible embodiment, the second positioning pin 60 is disposed between the legs 122. In this way, the middle mounting bracket 12 can only be moved downward by hoisting, so that the second positioning pin 60 abuts against the positioning hole 41 for positioning; further, the movement of the middle mounting bracket 12 in the horizontal direction is restricted.

[0059] In this embodiment, the battery bracket assembly further includes a bracket side enclosure 14, which is mounted on the sides of the middle mounting bracket 12 and the lower mounting bracket 11 and arranged opposite to each other. In this way, the upper mounting area 123 is further shielded.

[0060] Furthermore, the bracket side enclosure 14 includes a side enclosure vertical plate 141 and a side enclosure horizontal plate 142. The side enclosure horizontal plate 142 is used to connect the side enclosure vertical plate 141 and is connected to the lower side of the side enclosure vertical plate 141. The lower side mentioned here refers to the lower side of the plane where the horizontal support frame 121 is located. The advantage of this design is that by arranging the side enclosure horizontal plate 142 on the lower side, in addition to connecting the side enclosure vertical plate 141, it can also support the horizontal support frame 121, thereby improving the overall structural strength. Of course, the side enclosure horizontal plate 142 can also be arranged on the upper side of the side enclosure vertical plate 141 to further enhance the structural strength.

[0061] In addition, the battery bracket assembly also includes a charging port bracket 15 and a charging port cover 16, which are mounted on the top of the upper mounting bracket 13. In this way, the height of the charging port from the ground can be increased, and safety can be increased. Of course, the charging port bracket 15 and the charging port cover 16 can also be set on the side of the battery bracket assembly, or at any suitable position of the battery bracket assembly.

[0062] In addition, the battery bracket assembly further includes a connecting beam 17 and an adapter bracket 18, and the connecting beam 17 is connected to the bracket side enclosure 14 through the adapter bracket 18, for example, connected to the upper part of the bracket side enclosure 14. In this way, the overall structural strength of the battery bracket assembly is enhanced to ensure the stability of the battery in the lower mounting area 111 and the upper mounting area 123.

[0063] In addition, the battery bracket assembly also includes an auxiliary bracket 19, which is connected to the other adjacent side of the lower mounting bracket 11 and the upper mounting bracket 13 to fix the components connected to the lower mounting area 111 and the upper mounting area 123, such as high-voltage wiring harnesses, cooling pipes and other packaged parts.

[0064] The present application also discloses a vehicle, comprising the battery bracket assembly. The vehicle mentioned here may be a car, a pickup truck, etc.

[0065] In order to better realize modular assembly, the specific assembly steps are as follows: first, fix the lower battery on the multiple lower mounting areas 111 of the lower mounting bracket 11; secondly, install the middle mounting bracket 12 on the lower mounting bracket 11; secondly, assemble the first auxiliary bracket 191, the second auxiliary bracket 192 and the third auxiliary bracket 193 on the side of the middle mounting bracket 12 respectively; secondly, install the frame 20 between the two sets of legs 122; secondly, align the upper battery assembled on the battery bracket 40 with the first positioning pin 50 and the positioning hole 41 and install it on the middle mounting bracket 12; secondly, install the bracket side 14, the connecting beam 17, the adapter bracket 18, the charging port bracket 15 and the charging port cover 16 in sequence; finally, assemble the assembled battery bracket assembly to the bottom of the vehicle through the frame 20.
