A shaft locking member is installed between the suspension seat 2 and the rotating shaft 17. The gathering push plate 3 plays a role in pushing the clamping frame 6. The suspension plate 4 moves downward under the gravity of the battery pack 1, thereby driving the gathering push plate 3 to move to push the clamping frame 6, so that the clamping frame 6 can rotate around the rotating shaft 17 to be clamped on both sides of the I-shaped steel 33. At the same time, the corner ear 13 at the end of the clamping frame 6 is pressed against the upper corner of the I-shaped steel 33 from the inside to fix the suspension seat 2 on the I-shaped steel 33 by itself.

[0026] A lifting ring 15 is fixedly installed in the middle of the upper end of the suspension plate 4. The lifting ring 15 serves to facilitate the lifting and suspension of the suspension plate 4. Grooves 31 are provided at the front and rear ends of the suspension plate 4. A connecting shaft 28 is rotatably installed inside the groove 31. The groove 31 serves to support the connecting shaft 28. The end of the connecting shaft 28 passes through the side of the suspension plate 4. One end of the gathering push plate 3 is embedded in the outer surface of the connecting shaft 28. The connecting shaft 28 serves to connect the gathering push plate 3. A connecting plate 18 is fixedly installed at the inner corner of the corner ear 13. The end of the connecting plate 18 is fixed to the clamping frame 6.

[0028] A limiting shell 12 is fixedly installed in the middle of the upper end of the suspension seat 2, and a limiting column 10 is coaxially arranged inside the limiting shell 12. The limiting shell 12 and the limiting column 10 play a role in guiding the suspension plate 4.

[0029] The lower end of the limiting column 10 is coaxially inlaid with an anti-slip ring 9, which is integrally formed with the limiting column 10. The anti-slip ring 9 prevents the limiting shell 12 and the limiting column 10 from separating. The anti-slip ring 9 is attached to the inner wall of the limiting shell 12, and the outer side of the limiting shell 12 is wrapped with an opening spring 11. The lower end of the opening spring 11 is fixed to the upper end of the suspension seat 2. The opening spring 11 can ensure that when the suspension seat 2 is placed on the I-beam 33, the clamp 6 can be in an open state without hindering the placement of the suspension seat 2. The upper end of the opening spring 11 is fixed to the lower end of the suspension plate 4.

[0030] A limiting ear 8 extends from the lower corner of the suspension seat 2. There are four limiting ears 8. The limiting ears 8 can ensure that the suspension seat 2 is placed centered on the I-beam 33. The limiting ears 8 are integrally formed with the suspension seat 2. The lower edges of the opposite surfaces of the four limiting ears 8 are set as oblique guide edges 32. The oblique guide edges 32 can be guided during placement to facilitate the I-beam 33 to enter between the limiting ears 8 on both sides. Suspension frames 5 are fixedly installed on both sides of the suspension plate 4. T-shaped frames 30 are fixedly installed at the lower ends of the two suspension frames 5. The suspension frames 5, T-shaped frames 30 and battery racks 7 serve to connect the battery pack 1 and the suspension plate 4 together. The battery rack 7 is fixedly installed at the end of the T-shaped frame 30, and the end of the battery rack 7 is fixed to the battery pack 1.

[0031] The shaft locking member includes two L-shaped frames 16 respectively fixedly mounted on the middle part of the front and rear edges of the upper end of the suspension seat 2, and a guide sleeve 19 is fixedly mounted on the end of the L-shaped frame 16. The L-shaped frame 16 plays a role in fixing the guide sleeve 19, and a guide column 21 is fitted inside the guide sleeve 19. Both ends of the guide column 21 pass through the upper and lower ends of the guide sleeve 19. The guide sleeve 19 and the guide column 21 play a role in linearly guiding the arc seat 25. The lower end of the guide column 21 is fixedly mounted with an arc seat 25, and a convex locking ring 24 is coaxially inlaid in the middle part of the outer surface of the rotating shaft 17. The arc seat 25 plays a role in bearing the locking edge 26. The arc seat 25 is fitted to the outer surface of the convex locking ring 24, and a locking edge 26 is extended from the inner surface of the arc seat 25. The locking edge 26 passes through the outer surface of the convex locking ring 24, and the locking edge 26 can fix the convex locking ring 24, thereby locking the rotating shaft 17.

[0032] The outer surface of the convex lock ring 24 is provided with a lock groove 27, and the lock rib 26 is fitted inside the lock groove 27. The lock groove 27 plays a role in cooperating with the lock rib 26. The outer surface of the guide column 21 has two anti-rotation ribs 22 symmetrically extending, and the anti-rotation ribs 22 penetrate the inner wall of the guide sleeve 19. The anti-rotation ribs 22 play a role in preventing the arc seat 25 from rotating. The upper end of the guide column 21 has two symmetrically extending positioning ears 20, and the positioning ears 20 are fitted to the upper end of the guide sleeve 19. The positioning ears 20 play a role in preventing the guide sleeve 19 and the guide column 21 from separating. The outer side of the guide column 21 is wrapped with a compression spring 23, and one end of the compression spring 23 is fixed to the lower end of the guide sleeve 19. The compression spring 23 serves to fix the locking edge 26 in the locking groove 27. The other end of the compression spring 23 is fixed to the upper end of the arc seat 25. When the clamping frame 6 rotates around the rotating shaft 17 and is clamped on both sides of the I-shaped steel 33, the compression spring 23 will push the arc seat 25 so that the locking edge 26 on the arc seat 25 can be inserted into the locking groove 27 on the convex locking ring 24 to lock the rotating shaft 17, thereby limiting the clamping frame 6 on the rotating shaft 17, so that the corner ear 13 can always be pressed against the upper corner of the I-shaped steel 33 from the inside, so that the suspension seat 2 can be firmly fixed on the I-shaped steel 33.

[0033] When hanging, the suspension seat 2 is placed on the I-shaped steel 33 through the suspension ring 15. At this time, the suspension plate 4 moves downward under the gravity of the battery pack 1, thereby driving the gathering push plate 3 to move to push the clamping frame 6, so that the clamping frame 6 can rotate around the rotation axis 17 to clamp on both sides of the I-shaped steel 33. At the same time, the corner ears 13 at the ends of the clamping frame 6 are pressed against the upper corners of the I-shaped steel 33 from the inside to fix the suspension seat 2 on the I-shaped steel 33 by itself. At the same time, when the clamping frame 6 rotates around the rotation axis 17 as the center, the clamping frame 6 can rotate around the rotation axis 17 as the center. After rotating and clamping on both sides of the I-shaped steel 33, the compression spring 23 will push the arc seat 25, so that the locking edge 26 on the arc seat 25 can be inserted into the locking groove 27 on the convex locking ring 24, so as to lock the rotating shaft 17, and then limit the clamping frame 6 on the rotating shaft 17, so that the corner ear 13 can always be pressed against the upper corner of the I-shaped steel 33 from the inside, so that the suspension seat 2 can be firmly fixed on the I-shaped steel 33 to prevent the battery pack 1 from falling, thereby completing the suspension installation of the battery pack 1.
