The upper frame 2 includes two main beams 21 and two side beams 22. The two main beams 21 are arranged in parallel and at intervals. The two side beams 22 are respectively connected to both ends of the two main beams 21. The adjacent main beam 21 and side beam 22 are vertically connected. The first connection lug 23 has a flat wall 231 and reinforcing walls 232 connected to both sides of the bottom wall. The flat wall 231 is attached to the side beam 22 of the upper frame 2.

[0054] In a possible implementation, as Figure 3 , Figure 4 and Figure 6As shown, the first side frame 12 includes a plurality of columns, and second connecting lugs 121 are provided on the columns. One end of the second fastener 6 passes through the second connecting lug 121 and is connected to the upper layer frame 2, and the other end of the second fastener 6 is limited in the second connecting lug 121. The second connecting lug 121 has a fifth connecting hole 1211a, one main beam 21 has a sixth connecting hole 211, and the column has a seventh connecting hole (not shown). The second fastener 6 can be a bolt, and the bolt has a screw and a nut. In a state where the upper layer frame 2 is connected to the lower frame assembly 1, the rod body of the screw sequentially passes through the fifth connecting hole 1211a, the seventh connecting hole, and the sixth connecting hole 211 and is threadedly connected to the nut, and the cap body of the screw and the nut are respectively limited on both sides of the second connecting lug 121 and the main beam 21.

[0055] As Figure 3 and Figure 9 shown, the second connecting lug 121 includes a strip plate 1211, the strip plate 1211 is vertically connected to the column, both ends of the strip plate 1211 extend out of the column, and both ends of the strip plate 1211 are respectively connected to the upper layer frame 2 through the second fastener 6. Two fourth connecting holes 131 are respectively provided at both ends of the strip plate 1211, and both ends of the strip plate 1211 are respectively connected to the main beam 21 through the second fastener 6.

[0056] As Figure 3 and Figure 9 shown, the second connecting lug 121 includes a plurality of reinforcing plates 1212, and the reinforcing plates 1212 are respectively welded to the strip plate 1211 and the column. The reinforcing plates 1212 are vertically connected to the strip plate 1211 and the column. The reinforcing plates 1212 increase the structural strength between the main beam 21 and the column, and the structural strength of the welded connection is higher, so that the structural strength of the split battery frame of the present application is high.

[0057] In a possible implementation manner, as Figure 3 and Figure 8 shown, the vehicle body connecting portion 14 includes a first connecting hole 141 provided on the column and / or a third connecting lug 142 provided on the column.

The first plate body 1421 is perpendicular to the column, and an eighth connecting hole 1421a is provided on the first plate body 1421, and a bolt passes through the eighth connecting hole 1421a and is connected to the vehicle body.

[0058] In a possible implementation, positioning pins (not shown) are provided on both the bottom frame 11 and the upper frame 2. The positioning pin on the bottom frame 11 is in limit fit with the lower battery pack 3, and the positioning pin on the upper frame 2 is in limit fit with the upper battery pack 4. In the prior art, the battery pack is pushed onto the frame from the side, so it is impossible to arrange positioning pins, and accurate positioning of the battery pack cannot be achieved. Subsequently, the position of the battery pack needs to be continuously adjusted to make the mounting holes (not shown) on the battery pack coincide with the fixing holes (not shown) on the bottom frame 11 and the upper frame 2, and the adjustment operation is difficult. The separable battery frame of the present application is a detachable separable structure. Positioning pins can be provided on both the bottom frame 11 and the upper frame 2, and the positioning pins can be vertically arranged on the bottom frame 11 and the upper frame 2. Corresponding positioning and mating holes (not shown) are provided on both the upper battery pack 4 and the lower battery pack 3. When the upper battery pack 4 is installed on the upper frame 2, the positioning pin on the upper frame 2 penetrates through the corresponding positioning and mating hole on the upper battery pack 4. When the lower battery pack 3 is installed on the bottom frame 11, the positioning pin on the bottom frame 11 penetrates through the corresponding positioning and mating hole on the lower battery pack 3.

[0059] The assembly method of the separable battery frame of the present application is as follows:

[0060] Step 1: Separate the lower frame assembly 1 and the upper frame 2: The lower frame assembly 1 and the upper frame 2 are detachable structures. By removing the first fastener 5 and the second fastener 6, the separation operation of the lower frame assembly 1 and the upper frame 2 can be achieved.

[0061] Step 2: Install the upper battery pack 4 onto the upper frame 2: Lift the upper battery pack 4 above the upper frame 2 so that the positioning and mating holes penetrate through the corresponding positioning pins. After positioning, the mounting holes on the upper battery pack 4 coincide with the fixing holes on the upper frame 2, and then use bolts to connect and fix the upper battery pack 4 to the upper frame 2. As shown in Figure 5 the figure, the positioning and mating of the positioning pins and the positioning and mating holes achieve the accurate positioning of the upper battery pack 4. Subsequently, it is not necessary to adjust the position of the upper battery pack 4, and one person can complete the installation operation with the help of a lifting device, which is very convenient and labor-saving.

[0062] Step 3: Install the lower battery pack 3 onto the bottom frame 11: Lift the lower battery pack 3 above the bottom frame 11 so that the positioning and mating holes penetrate through the corresponding positioning pins. After positioning, the mounting holes on the lower battery pack 3 coincide with the fixing holes on the bottom frame 11, and then use bolts to connect and fix the lower battery pack 3 to the bottom frame 11. As shown in Figure 6As shown, the positioning fit between the positioning pin and the positioning mating hole realizes the precise positioning of the lower battery pack 3. Subsequently, the position of the lower battery pack 3 does not need to be adjusted, and one person can complete the installation operation, which is very convenient and labor-saving.

[0063] Step 4: Install and fix the upper frame 2 with the battery pack assembled thereon onto the lower frame assembly 1 with the battery pack assembled thereon: Lift and suspend the upper frame 2 with the battery pack assembled thereon above the lower frame assembly 1 with the battery pack assembled thereon, so that the positions of the second connection holes 2311, the third connection holes, and the fourth connection holes 131 are opposite to each other, and the positions of the fifth connection hole 1211a, the sixth connection hole 211, and the seventh connection hole are opposite to each other. Then, use the first fastener 5 and the second fastener 6 for connection and fixation respectively.

[0064] It should be noted that when performing the assembly operation of the split battery frame of the present application, the operations of Step 2 and Step 3 can be carried out synchronously, or the operation of Step 3 can be carried out first and then the operation of Step 2.
