[0022] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0023] Example:

[0024] like Figure 1-Figure 4 As shown, a lightweight battery module pallet includes a pallet body 1, a battery slot 2 is opened on the top of the pallet body 1, a battery body 3 is placed inside the battery slot 2, a flame retardant frame 4 is clamped on the inner side of the top of the pallet body 1, and mounting feet 6 are symmetrically provided on the outer edge of the surface of the pallet body 1.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the battery body 3 is placed on the inner side of the battery slot 2, and then the bottom of the flame retardant frame 4 is inserted between the inner side of the battery slot 2 and the battery body 3, restricting the battery body 3 to the inner side of the battery slot 2. This can improve the stability of the battery body 3, and the flame retardant frame 4 can improve the safety of use.

[0027] In another embodiment, if Figure 4 As shown, a fixed bottom groove 8 is symmetrically provided at the bottom of the tray body 1 , and a plurality of first heat sinks 9 are provided inside the fixed bottom groove 8 .

[0028] The bottom groove 8 is convenient for fixing and can reduce the weight of the entire tray body 1. At the same time, the first heat sink 9 can absorb the heat generated by the entire body during use and dissipate it to the outside.

[0029] In another embodiment, if Figure 2 As shown, the top ends of the tray body 1 are both provided with fixed top grooves 10 , the inner side of the fixed top grooves 10 is provided with second heat sinks 11 , and the surfaces of both ends of the tray body 1 are both provided with fixed through grooves 12 .

[0030] The fixing top groove 10 and the fixing through groove 12 can reduce the overall weight, and the second heat sink 11 can quickly absorb the heat and dissipate it to the outside, thereby dissipating the heat.

[0031] In another embodiment, if Figure 2 As shown, both ends of the front and rear surfaces of the tray body 1 are provided with fixed installation slots 13 , the inner side of the fixed installation slots 13 is movably connected with a movable installation block 14 , and the surface of the movable installation block 14 is fixedly connected with a third heat sink 15 .

[0032] The end of the movable mounting block 14 can be inserted into the inner side of the fixed mounting slot 13 to install and fix the third heat sink 15, so that the third heat sink 15 can stably absorb the heat generated during the use of the whole and dissipate it to the outside.

[0033] In another embodiment, if Figure 3 As shown, the outer side of the bottom end surface of the flame retardant frame 4 is pressed and fitted with the inner side surface of the battery container 2 and the outer side surface of the battery body 3 .

[0034] When the bottom of the flame retardant frame 4 is inserted into the inner side of the battery slot 2 and pressed and fitted between the battery body 3 , the battery body 3 can be stably restricted inside the battery slot 2 for use, which is easy to operate.

[0035] In another embodiment, if Figure 1 As shown, a reinforcing support block 7 is fixedly connected between the bottom edge of the mounting foot 6 and the outer side of the surface of the tray body 1 .

[0036] Strengthening the support block 7 can improve the connection strength between the tray body 1 and the mounting legs 6, so that the whole can be stably connected and fixed to the electric vehicle.

[0037] In another embodiment, if Figure 2 As shown, the cross-sectional shape of the fixed installation slot 13 is T-shaped, and the outer side of the end surface of the movable installation block 14 is in contact with the inner side of the fixed installation slot 13 .

[0038] The movable installation block 14 can be stably stuck on the inner side of the fixed installation slot 13 to achieve connection and fixation.

[0039] The working principle of the utility model is as follows: during use, the battery body 3 is placed on the inner side of the battery slot 2, and then the bottom end of the flame retardant frame 4 is inserted into the inner side of the battery slot 2, and squeezed and fitted with the battery body 3, so that the battery body 3 can be stably located on the inner side of the battery slot 2 for use, and then the end of the movable mounting block 14 is inserted into the inner side of the fixed mounting slot 13, and the movable mounting block 14 and the third heat sink 15 are installed and fixed, and finally the mounting feet 6 are connected and fixed to the electric vehicle by bolts. When in use, the fixed bottom slot 8, the fixed top slot 10 and the fixed through slot 12 can reduce the overall weight, and at the same time the first heat sink 9, the second heat sink 11 and the third heat sink 15 can stably absorb the heat generated during use and dissipate it to the outside for heat dissipation treatment. The overall structure is simple and easy to use.

[0040] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
