In some embodiments, the support plate 10 has a thickness of 2.5 mm.

In some embodiments, as shown in FIG. 2, the support leg 20 includes: a first support leg 210 and a second support leg 220. The first support legs 210 are disposed on both sides of the width direction of the support plate 10 and one side of the length direction of the support plate 10, for example, the width direction of the support plate 10 is the front-back direction, and the length direction is the left-right direction, so that the first support legs 210 can be disposed on the left side, the right side, and the rear side of the support plate 10, the number and the fixing positions of the support legs 20 around the first installation part 101 and the second installation part 102 can be increased, and the strength of the support plate 10 can be further improved.

The BDU assembly is a gate for the electric energy of the battery pack to enter and exit, is connected with the high-voltage load of the whole vehicle and the quick-charging harness through a high-voltage electrical interface, comprises a pre-charging circuit, a total positive relay, a total negative relay, a quick-charging relay and the like, and is controlled by the main board, and the BMS assembly is a battery management system of the vehicle.

In some embodiments, as shown in FIG. 2, the second support legs 220 are provided in one piece, and according to the foregoing, since the space available for support at the front portion of the support plate 10 is small, the strength of the front portion of the support plate 10 can be ensured by providing one second support leg 220, and the arrangement is also convenient.

In some embodiments, there are at least two first support legs 210 on either side of the support plate 10, and at least two first support legs 210 are spaced apart from each other, i.e., more first support legs 210 are provided on each side of the support plate 10, which is beneficial to increase the strength of the support plate 10. For example, two first support legs 210 are provided on each of the left, right, and rear sides of the support plate 10, and the two first support legs 210 are disposed to be spaced apart from each other. Of course, this is only an example, and the number of the first support legs 210 may be specifically set according to the situation, and is not described herein again.

Alternatively, the first and

second support legs

210 and 220 are coupled to the support plate 10 by fasteners, which may be bolts. Since the support legs 20 and the support plate 10 are fixed by bolts, the number of the support legs 20 is large, the strength of the support plate 10 is high, and the deformation and displacement are small, so that the stress at the stress concentration positions of the support legs 20 and the support plate 10 can be small, and the risk of fracture failure of the module bracket 100 due to stress concentration can be reduced.

Alternatively, as shown in fig. 2, the leg reinforcing bead 202 of the first support leg 210 is a first leg reinforcing bead 21, and the first leg reinforcing bead 21 includes: a plurality of first horizontal muscle 211, a plurality of first horizontal muscle 211 are along the extending direction of type groove 201 spaced apart the setting in proper order. By adopting the mode, the rigidity of the first support leg 210 can be improved, the deformation resistance of the first support leg is enhanced, the deformation of the module bracket 100 is reduced, and the risk that the bracket touches a module or a wire harness downwards is reduced. For example, the number of the first transverse ribs 211 may be three, and certainly, the number of the first transverse ribs 211 may also be other values, which may be specifically set according to the situation, and is not described herein again.

In some embodiments, as shown in FIG. 2, the leg stiffener 202 of the second support leg 220 is a second leg stiffener 22, and the second leg stiffener 22 includes: the plurality of second transverse ribs 221 and the plurality of second inclined ribs 222 are arranged at intervals in sequence along the extending direction of the groove 201; two ends of each second tilted rib 222 are respectively connected to two opposite sides of the slot 201. Referring to the foregoing, since the space for supporting the front portion of the support plate 10 is small, the number of the support legs 20 that can be installed is small, and therefore, the strength of the single support leg 20 needs to be improved, and the strength of the second support leg 220 can be greatly improved by the cooperation of the plurality of second transverse ribs 221 and the plurality of second oblique ribs 222, so that the second support leg has a good resistance to deformation.

For example, the number of the second transverse ribs 221 is three, the number of the second inclined ribs 222 is two, and two second inclined ribs 222 are disposed on the upper and lower sides of the groove 201. Of course, the number of the second transverse ribs 221 and the second oblique ribs 222 may also be other values, and may be specifically set according to the situation, which is not described herein again.
