[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0035] Traditional light logistics vehicles are mainly converted from gasoline-powered trucks to electric vehicles, with the chassis remaining unchanged and the battery pack mounted on both sides of the vehicle. This allows for rapid market entry while meeting the load-bearing requirements of existing vehicles. Specifically, the battery pack is suspended in the middle of the chassis and assembled in the middle section of the chassis. The battery pack uses a lower support bracket, symmetrically arranged on both sides. The lower support bracket is first assembled onto the battery pack and tightened with M12 bolts; the upper six lifting lug brackets are pre-assembled with the middle section of the chassis and then tightened with M10 bolts.

[0036] The battery pack with its integrated lower support bracket is moved horizontally to the corresponding position using an AGV tool cart, then moved upwards to align the mounting holes of the lower support bracket with those of the lifting lug bracket. Bolts are then inserted in a Z-direction to install the lifting lug bracket and lower support bracket into place. Finally, the bolts are tightened to complete the mid-mounted battery pack assembly. This solution suffers from the issue of a relatively heavy battery bracket, estimated at 36kg, which does not meet the higher requirements for overall vehicle lightweighting.

[0037] like Figures 1-12 As shown, the lightweight power battery bracket provided in this embodiment includes: side beam brackets 1 disposed on the left and right sides of the vehicle frame 4. The side beam brackets 1 have a bent structure. A first threaded hole 13 is provided on one side of the bent structure of the side beam brackets 1 for connection with the battery pack 3 through the first threaded hole 13. A positioning pin 11 is provided on the other side of the bent structure of the side beam brackets 1. A Z-direction through bracket 2 is connected to the side beam brackets 1 through the positioning pin 11. The Z-direction through bracket 2 is also connected to the vehicle frame 4.

[0038] The lightweight power battery bracket of the present invention has a side beam bracket 1 with one side of its bent structure connected to the battery pack 3 via a first threaded hole 13, and the other side of the bent structure connected to a Z-direction through bracket 2 via a positioning pin 11. The Z-direction through bracket 2 is also connected to the vehicle frame 4. The original lower support structure has been changed to an upper suspension structure, reducing the amount of Z-direction material used and lightening the weight of the side beam bracket. At the same time, the first threaded hole 13 is close to the bending edge of the bent structure, eliminating the need for a reinforcing plate and further reducing material usage.

[0039] Among them, such as Figure 2 and Figure 10 As shown, each of the side beam supports 1 includes a horizontal portion 14 and an inclined portion 15, with the horizontal portion 14 located inside the inclined portion 15. A first threaded hole 13 is provided on the horizontal portion 14, and a second threaded hole is provided on the battery pack 3. The first threaded hole 13 matches the second threaded hole so that the battery pack 3 is fixed to the side beam support 1 by a first bolt 16 passing through the first threaded hole 13 and the second threaded hole in sequence. A positioning pin 11 is provided on the inclined portion 15, and the positioning pin 11 is arranged vertically on the outside of the inclined portion 15. Specifically, there are 15 first threaded holes 13, divided into 5 groups of 3, with the first threaded holes 13 in each group evenly distributed on the horizontal portion 14, and the first threaded holes 13 in each group are evenly distributed. There are 3 positioning pins 11, evenly distributed on the outside of the inclined portion 15, and the positioning pins 11 are of type M12. Correspondingly, there are also 3 Z-direction through-braces 2 corresponding to the same side beam support 1.

[0040] Furthermore, a plurality of projection weld nuts 12 are provided around the positioning pin 11 on the inclined portion 15, and the side beam bracket 1 is assembled with the Z-direction through bracket 2 through each of the projection weld nuts 12; the number of projection weld nuts 12 corresponding to the same positioning pin 11 is 4, and the projection weld nuts 12 corresponding to the same positioning pin 11 are distributed in a rectangular shape. In one embodiment of the present invention, the projection weld nuts 12 are of type M10.

[0041] Furthermore, such as Figure 1 As shown, the top end of the Z-axis through-bracing 2 is connected to the vehicle frame 4, and the bottom end of the Z-axis through-bracing 2 is connected to the side beam bracket 1. Figure 3 , Figure 4 , Figure 11 and Figure 12As shown, the Z-direction through-bracing 2 includes two narrow side structures 23 extending vertically along the Z direction. A U-shaped protrusion 24, which bends from the inside to the outside and runs vertically through the two narrow side structures 23, is provided between them. The two narrow side structures 23 and the U-shaped protrusion 24 are integrally formed. A pad 21 is provided on the inner side between the two narrow side structures 23. The pad 21 is roughly square in shape, and a square hole 212 is provided in the middle of the pad 21. The two sides of each narrow side structure 23 are connected to the pad 21 by a weld 22.

[0042] Furthermore, a U-shaped groove 25 is provided at the lower end of the U-shaped protrusion structure 24, and the positioning pin 11 of the side beam bracket 1 passes through the U-shaped groove 25 to position the side beam bracket 1 and the Z-direction through bracket 2.

[0043] Furthermore, each of the two narrow-sided structures 23 has two third threaded holes 26 near the U-shaped groove 25. Each third threaded hole 26 matches the corresponding projection weld nut 12, allowing a second bolt 29 (e.g., ...) to pass through the third threaded hole 26 to reach the projection weld nut 12. Figure 8 As shown, the side beam bracket 1 and the Z-direction through bracket 2 are fixed, and the second bolt 29 is of type M10.

[0044] Furthermore, in one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the U-shaped groove 25 has the shape of a rectangle extending along the Z direction and semicircles disposed on the upper and lower sides of the rectangle, correspondingly, as... Figure 2 As shown, the side beam support 1 has a right-angle structure, and the inclined portion 15 is perpendicular to the horizontal portion 14. In another embodiment of the invention, as... Figure 11 and Figure 12 As shown, the U-shaped groove 25 has the shape of a rectangle extending along the Z direction and a semicircle disposed on the upper side of the rectangle, and the bottom end of the U-shaped groove 25 is flush with the bottom end of the U-shaped protrusion structure. Correspondingly, as... Figure 10 As shown, the side beam support 1 has a bent guide structure. The angle between the inclined portion 15 and the horizontal portion 14 is an obtuse angle. A folded edge structure 211 is provided at the top of the inclined portion 15. The folded edge structure 211 and the horizontal portion 14 are located on the same side of the inclined portion 15, and the folded edge structure 211 is inclined upward. In specific implementations, the appropriate option can be selected based on battery pack installation, after-sales service equipment, and ease of disassembly and assembly.

[0045] Furthermore, the four corner edges of the pad 21 are respectively provided with fourth threaded holes 27, and the two narrow side structures 23 are provided with fifth threaded holes 28 at positions corresponding to the fourth threaded holes 27. The frame 4 is provided with a sixth threaded hole to allow the passage of a third bolt 210 (e.g., passing through the sixth threaded hole, the fifth threaded hole 28, and the fourth threaded hole 27 in sequence). Figure 6 As shown, the Z-axis through-bracing 2 is fixed to the vehicle frame 4. During assembly, the same locating pin 11 provides lateral positioning for the four second bolts 29 passing through the Z-axis through-bracing. After positioning, the battery pack 3 is lowered freely. At this time, the locating pin 11 bears the weight of the entire battery pack 3, and positioning is completed under the influence of the battery pack 3's own weight. After positioning, the four second bolts 29 around the locating pin 11 are assembled, and the third bolts 210 used to connect the Z-axis through-bracing 2 and the vehicle frame 4 are tightened simultaneously to complete the system assembly.

[0046] In one embodiment of the present invention, when the U-shaped groove 25 is a rectangle extending along the Z direction and semicircles are provided on the upper and lower sides of the rectangle, and correspondingly, the side beam support 1 has a right-angle structure, and the inclined part 15 is perpendicular to the horizontal part 14, the assembly process of the lightweight power battery bracket of the present invention is as follows:

[0047] like Figure 5 As shown, first, pre-install and tighten the side beam bracket 1 and the battery pack 3. Specifically, place the side beam bracket 1 on the left and right sides in the corresponding holes (second threaded holes) of the battery pack 3. In the Z direction, insert the first bolt 16 (M12 type) downward through the first threaded hole 13 of the side beam bracket 1 and the second threaded hole of the battery pack 3, and place the nut below accordingly. Once assembled in place, set the torque to complete the first step of installation.

[0048] Then, as Figure 6 and Figure 7 As shown, the Z-direction through bracket 2 is assembled onto the outer surface of the frame 4: the third bolt 210 is passed through the sixth threaded hole on the frame, the fifth threaded hole 28 on the narrow side structure 23 of the Z-direction through bracket 2, and the fourth threaded hole 27 on the pad of the Z-direction through bracket 2 in sequence, with the nut on the outside, the nut is only screwed in but not tightened, and the Z-direction through bracket 2 can move outward along the third bolt 210.

[0049] Next, as Figure 8As shown, manually move the Z-direction through bracket 2: Move the side beam bracket 1 with battery pack 3 horizontally under the vehicle frame 4. After moving it to the predetermined position in the Z direction, manually move the Z-direction through bracket 2 inward along the position of the third bolt 210 of the vehicle frame 4. At the same time, fit the U-shaped groove 25 below the Z-direction through bracket 2 onto the positioning pin 11 of the side beam bracket 1 to achieve the pre-installation of the preset position. After all 6 Z-direction through brackets 2 are assembled in place, remove the mounting platform under the battery pack 3. Under the action of its own weight, the battery pack 3 descends freely, and the holes of the 6 positioning pins 11 of the side beam bracket 1 reach the preset position. At this time, the 4 projection weld nuts 12 around the positioning pins 11 are aligned with the third threaded holes 26 of the Z-direction through bracket 2. Insert 4 second bolts 29 of type M10 through the corresponding third threaded holes 26 of the Z-direction through bracket 2 and lock them onto the corresponding projection weld nuts 12 of the side beam bracket 1 to achieve the lower assembly of the Z-direction through bracket 2.

[0050] After completing the above steps, first tighten the third bolt 210 used to connect the Z-direction through bracket 2 and the frame 4, and then tighten the second bolt 29 used to connect the Z-direction through bracket 2 and the side beam bracket 1 to complete the assembly.

[0051] like Figure 9 As shown, when replacing or repairing battery pack 3 in the aftermarket, first loosen the six third bolts 210 used to connect the Z-direction through bracket 2 and the frame 4, allowing for Y-direction movement. Use a forklift or lifting platform to align battery pack 3 with the Z-direction through bracket 2, lift it into position in the Z-direction, and manually engage the U-shaped groove 25 pre-drilled in the Z-direction through bracket 2 with the positioning pin 11 of the side beam bracket 1 from front to back. Lower battery pack 3 to hang freely to achieve positioning. Then, assemble the second bolts 29 used to connect the Z-direction through bracket 2 and the side beam bracket 1, and tighten the third bolts 210 used to connect the Z-direction through bracket 2 and the frame 4 to achieve reliable installation. It is evident that when replacing the battery in the aftermarket, using the aforementioned method, no special installation platform is required; positioning is achieved solely by the positioning pins 11, allowing for precise lowering and positioning of the battery pack 3.

[0052] In another embodiment of the present invention, when the U-shaped groove 25 is a rectangle extending along the Z direction and a semicircle is provided on the upper side of the rectangle, and the bottom end of the U-shaped groove 25 is flush with the bottom end of the U-shaped protrusion structure, and correspondingly, the side beam bracket 1 has a bent guide structure, the assembly process of the lightweight power battery bracket of the present invention is as follows:

[0053] As with the aforementioned installation method, first assemble the Z-direction through bracket 2 and the frame 4 into place (do not tighten, and make slight adjustments along the direction of the bolts).

[0054] Then, pre-install and tighten the battery pack 3 and the side beam bracket 1. After assembly, use the battery pack mounting platform to lift it and move it to the corresponding position. Lift it in the Z direction. Align the positioning pin 11 of the side beam bracket 1 with the U-shaped groove 25 of the Z-direction through bracket 2. When the positioning pin 11 is locked, the positioning is completed. Keep the battery pack mounting platform still and install the second bolt 29 at the bottom of the Z-direction through bracket 2. After completion, remove the battery mounting platform (generally an AGV trolley).

[0055] Correspondingly, the present invention also provides a new energy logistics vehicle, including the aforementioned lightweight power battery bracket.

[0056] The lightweight power battery bracket and new energy logistics vehicle provided by this invention offer a lightweight battery bracket. One side of the bent structure of the side beam bracket is connected to the battery pack through a first threaded hole, and the other side of the bent structure is connected to a Z-direction through bracket through a positioning pin. The original lower support adapter bracket is replaced with an upper hanging structure, and the Z-direction through bracket is set to achieve assembly of the upper part with the vehicle frame and the lower part with the side beam bracket. The assembly process is simple and the positioning is accurate. It is used to assemble a single-pack centrally located battery pack. While ensuring the assembly strength of the battery pack, it minimizes the weight of the battery bracket, contributing more than 15 kg to the overall vehicle weight reduction. It also facilitates battery disassembly and assembly in the aftermarket, reduces equipment platform requirements, and improves installation accuracy.
