[0027] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0028] A large-volume frame structure includes a front frame body 1, a pair of side frames 2 and a rear frame body 3. The side frame body 2 includes a battery support part 4, an inclined connection part 5 and a rear box support part 6. The battery support part 4, the inclined connection part 5 and the rear box support part 6 form a frame. The front end of the frame is used to place batteries and pedals, and the rear end of the frame is used to place a seat bucket. A support clamp 7 is also provided on the rear box support part 6. The support clamp 7 is used to connect the side frame body 2 and the shock-absorbing spring 8 at the wheel. An avoidance groove 9 is formed between the two support clamps 7. The inclined connection part 5 and the rear box support part 6 form a storage groove 10. The storage groove 10 is used to install a seat bucket storage bin. By directly arranging the support clamp 7 on the rear box support part 6, the space between the support clamp 7 and the rear frame body 3 can still be used, thereby increasing space utilization. By arranging the rear box support part 6, the overall structural strength of the side frame body 2 is guaranteed, while reducing the use of materials and reducing costs.

[0029] A bending joint 11 is provided between the inclined connection part 5 and the rear box support part 6. The support clamp 7 is arranged on the rear box support part 6 and close to the rear frame 3, so as to ensure the structural strength at the support clamp 7. The rear frame 3 includes a seat frame 12 and a locking block 13. The locking block 13 is installed on the rear box support part 6. The seat frame 12 is U-shaped and is installed on the locking block 13. Seat back mounting buckles 14 are provided on both sides of the seat frame 12 and the rear box support part 6. By additionally providing the seat frame 12 and installing it on the locking block 13, the overall size of the chair is reduced, and the use of materials is reduced while ensuring the structural strength, reducing costs and reducing the overall weight of the vehicle.

[0030] The lock block 13 includes a U-shaped mounting frame 15 and a lock core 16. The U-shaped mounting frame 15 is directly welded to the rear box support portion 6, and the lock core 16 is fixed in the U-shaped mounting frame 15. Through holes 17 are opened on both sides of the U-shaped mounting frame 15. The two sides of the chair frame 12 pass through the two through holes 17 and are fixed to the U-shaped mounting frame 15. After the rear chair is installed, the U-shaped mounting frame 15, the chair frame 12 and the rear box support portion 6 are formed into one body, thereby ensuring the structural strength.

[0031] The support clamp 7 is welded and fixed to the rear frame 3. A U-shaped clamping groove 18 is provided in the middle of the support clamp 7. The bottom of the U-shaped clamping groove 18 is connected to the shock-absorbing spring 8. By providing the U-shaped clamping groove 18, the structural strength of the support clamp 7 itself is ensured.

[0032] A seat bucket support frame 19 is also provided between the two battery support parts 4, which is welded to the battery support part 4 and is arranged in an arch shape. A lower frame body 20 is also provided at the lower end of the side frame body 2, and a transverse support rod 21 is provided between the lower frame bodies 20. A battery mounting box 22 is also provided at the bottom of the lower frame body 20. By arranging the seat bucket support frame 19 between the battery support parts 4 and arranging the seat bucket support frame 19 in an arch shape, the structural strength of the seat bucket support frame 19 is increased while ensuring space utilization. The lower frame body 20 and the transverse support rod 21 further increase the overall structural strength of the frame. By arranging the battery mounting box 22, the battery can be easily installed while the bottom of the battery is protected.

[0033] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
