The main layer 1 is fixedly arranged on the top of the support layer 2, and the battery compartment 3 is fixedly arranged on the bottom of the support layer 2. The main layer 1 is used to support the body structure of the electric vehicle, and the support layer 2 is used to support the power structure of the electric vehicle and serve as the overall skeleton of the electric vehicle. The battery compartment 3 is a rectangular frame structure, and the battery compartment 3 is used to support the battery pack 8 of the electric vehicle. The battery compartment 3 is provided with a plurality of rectangular battery cavities, so that each battery pack 8 is placed vertically on both sides of the battery compartment 3 perpendicular to the forward direction of the vehicle.

[0033] Reference Figure 1 A plurality of support rods 4 are arranged between the main body layer 1 and the support layer 2, one end of each support rod 4 is fixedly connected to the support layer 2, and the other end of each support rod 4 is connected to the main body layer 1. Each support rod 4 is evenly distributed on both sides of the support layer 2 and obliquely supports the main body layer 1, thereby making the connection between the main body layer 1 and the support layer 2 more stable, and at the same time, it is easier to transfer the force to the support layer 2 using the main body layer 1.

[0034] Reference Figure 1 The main body layer 1 includes a main body 11 and a head 12, which are respectively fixedly connected to the support layer 2. The head 12 is arranged on the side close to the vehicle's forward direction, and the main body 11 is arranged on the side away from the vehicle's forward direction. A connecting frame 13 is arranged between the main body 11 and the head 12. The connecting frame 13 is inclined from top to bottom from close to the main body 11 to close to the head 12. The surface height of the head 12 is lower than the surface height of the main body 11. One end of the connecting frame 13 is fixedly connected to the main body 11, and the other end of the connecting frame 13 is fixedly connected to the head 12. The connecting frame 13 obliquely supports the main body 11.

[0035] By dividing the integrated frame on a plane into functional areas, the vehicle chassis has a frame structure for placing the battery pack 8, and the vehicle chassis structurally allows the battery pack 8 to be pulled out from both sides of the forward direction of the vehicle chassis, thereby improving the problem of producing a vehicle chassis adapted for quick disassembly and assembly of the battery pack 8 without meeting the demand for quick disassembly and assembly of the battery pack 8, thereby making the disassembly and assembly structure of the battery pack 8 more reasonable.

[0036] Reference Figure 2 A pull-out battery replacement structure for an electric vehicle also includes a accommodating component 5, a driving component 6 and a locking component 7. The accommodating component 5 is arranged in the battery cavity, the driving component 6 and the locking component 7 are both arranged in the battery compartment 3, the accommodating component 5 is used to accommodate the battery pack 8, the driving component 6 is used to drive the accommodating component 5 to be pulled out, and the locking component 7 is used to lock the position of the accommodating component 5.

[0037] Reference Figure 2 and Figure 3The accommodating assembly 5 includes four accommodating boxes 51, each of which is vertically arranged on both sides of the battery compartment 3 and perpendicular to the forward direction of the vehicle. Each of the accommodating boxes 51 is slidably fitted in each battery cavity and evenly distributed on both sides of the battery compartment 3, and each battery pack 8 is placed in each of the accommodating boxes 51.

[0038] Reference Figure 2 and Figure 3 The accommodating assembly 5 also includes four groups of positioning blocks 52, each group includes eight positioning blocks 52, and each group of positioning blocks 52 is fixedly connected to each accommodating box 51, and each group of positioning blocks 52 horizontally positions each battery pack 8 near the four corners of the accommodating box 51.

[0039] Reference Figure 2 and Figure 3 The accommodating assembly 5 further includes four positioning plates 53, four positioning torsion springs 54 and four positioning rods 55. Each positioning plate 53 is rotatably arranged on the side of the battery compartment 3 close to the supporting layer 2. Each positioning plate 53 is respectively located at the top of each accommodating box 51. The positioning plate 53 includes a positioning portion 531 and abutting portion 532. The positioning portion 531 and the abutting portion 532 are fixedly connected. When the battery pack 8 is placed in the accommodating box 51, the positioning portion 531 abuts against the battery pack 8. Each positioning rod 55 is respectively fixedly arranged on the top of each accommodating box 51. Each positioning rod 55 abuts against each abutting portion 532. When the accommodating box 51 is in contact with the battery pack 8, the positioning portion 531 abuts against the battery pack 8. When the accommodating box 51 is in contact with the battery pack 8, the positioning rod 55 abuts against each abutting portion 532. When the storage box 51 is opened, the positioning rod 55 disengages from the abutment with the tightening portion 532, slides with the storage box 51 to abut against the positioning portion 531, and pushes the positioning portion 531 to rotate away from the battery pack 8 until the positioning portion 531 loses its positioning in the direction of the top of the battery pack 8, thereby allowing the battery pack 8 to be smoothly taken out. Each positioning torsion spring 54 is respectively arranged on the positioning plate 53, and one end of each positioning torsion spring 54 is fixedly connected to the battery compartment 3, and the other end of each positioning torsion spring 54 is respectively fixedly connected to each positioning plate 53, thereby always pushing each positioning portion 531 to rotate towards the direction of the battery pack 8.

The two driving racks 62 are both meshed with the driving gear 61. The driving gear 61 rotates and at the same time drives the two driving racks 62 to slide in a direction of approaching or moving away from each other, thereby driving the accommodating boxes 51 on both sides to slide along each battery cavity in a direction of approaching or moving away from each other, thereby completing the driving of each accommodating box 51 to open and close.

[0041] The driving assembly 6 also includes a driving motor, which is fixedly disposed on the battery compartment 3 . The output shaft of the driving motor is coaxially fixed with the driving gear 61 . When the driving motor is driven, the output shaft of the driving motor rotates, and the driving gear 61 rotates.

One end of the driving torsion spring 63 is fixedly connected to the driving gear 61, and the other end of the driving torsion spring 63 is fixedly connected to the battery compartment 3, so that when each storage box 51 needs to be opened, the torque of the driving torsion spring 63 is released, pushing the driving gear 61 to rotate, so that each storage box 51 is quickly opened.

[0043] Reference Figure 5 and Figure 6 The locking assembly 7 includes a locking block 71 and a locking spring 72. The locking block 71 is slidably fitted in the battery compartment 3.

The locking gear 74 is coaxially fixed with the lock core 73. When the key rotates the lock core 73, the locking gear 74 rotates. A plurality of locking teeth are arranged on one side of the locking block 71, and each locking tooth is engaged with the locking gear 74.

[0045] Reference Figure 7 , Figure 8 as well as Fig. 9 The battery pack 8 includes a battery body 81, a plurality of sliding wheels 82 and a plurality of pull-out rings 83. The battery body 81 is rectangular. Each positioning block 52 positions the four corners of the battery body 81 close to the storage box 51 in the horizontal direction.
