Two symmetrically arranged driving screws are rotatably provided inside each rotation ring. A slider is threadedly sleeved on the rod wall of the driving screw. The end of the slider is provided with a support beam through a connection mechanism. An installation hole is opened inside the support beam;

[0009] A battery module is arranged inside the battery pack bottom case. A connection frame is fixedly sleeved on the outer wall of the battery module. A connection plate is fixedly provided on the outer wall of the connection frame. A bolt is connected between the connection plate and the installation hole.

[0010] Preferably, the slider is arranged in an L shape.

[0011] Preferably, the connecting mechanism includes two symmetrically arranged clamping blocks. A through groove is formed at the end of the slider. Moving plates are slidably inserted through both sides of the through groove. The other end of the moving plate is located in the through groove and fixedly connected to the clamping block. A slot for inserting the slider is formed at the end of the support beam. Card slots are formed on both sides of the inner wall of the slot. The clamping block passes through the through hole and is inserted into the card slot. A spring is fixedly arranged between the two moving plates.

[0012] Preferably, a cover plate is covered outside the bottom shell of the battery pack. A sealing groove for the slider to pass through is formed on the side of the cover plate.

[0013] Further, the side wall of the clamping block is arranged in an inclined plane.

[0025] The embodiment of the present invention discloses a general battery pack for electric vehicles.

[0026] Embodiment 1

[0027] The present invention provides a general battery pack for electric vehicles as shown in Figures 1-3 which includes a battery pack bottom case 1. Both sides of the outer wall of the battery pack bottom case 1 are fixedly provided with support plates 2. Both sides of the outer wall of the battery pack bottom case 1 are fixedly provided with a plurality of rotating rings 3 arranged at intervals. Each rotating ring 3 internally rotates two symmetrically arranged driving screws 4. A slide block 5 is threadedly sleeved on the rod wall of the driving screw 4. The slide block 5 is L-shaped. The side wall of the slide block 5 is in contact and cooperation with the outer wall of the battery pack bottom case 1. The end of the slide block 5 is provided with a support beam 6 through a connecting mechanism. An installation hole 7 is opened inside the support beam 6. A cover plate 15 is covered outside the battery pack bottom case 1. A sealing groove 16 for the slide block 5 to pass through is opened on the side of the cover plate 15;

[0028] A battery module 8 is arranged inside the battery pack bottom case 1. A connecting frame 9 is fixedly sleeved on the outer wall of the battery module 8. A connecting plate 10 is fixedly provided on the outer wall of the connecting frame 9. A bolt 11 is connected between the connecting plate 10 and the installation hole 7.

[0029] Before assembling the internal battery module of the battery pack, the plurality of driving screws 4 can be adjusted according to the specifications of the battery module 8, so that the slide block 5 slides along the outer wall of the battery pack bottom case 1 and drives the support beam 6 to move, adjusting the installation space between two adjacent support beams 6 to be suitable for the installation of the battery module 8. After the position of the support beam 6 is fixed, the battery module 8 can be placed inside the battery pack bottom case 1, and the bolt 11 is connected to the support beam 6 through the connecting frame 9 and the connecting plate 10, thus completing the setting of the battery module 8. After a plurality of battery modules 8 are all arranged inside the battery pack bottom case 1, the sealing groove 16 is opened on the outside of the cover plate 15 according to the position of the slide block 5, and the cover plate 15 is covered above the battery pack bottom case 1 to complete the composition of the battery pack.

[0030] Embodiment 2

[0031] Embodiment 2 On the basis of Embodiment 1, in order to be able to disassemble the support beam 6 when the installation position of the support beam 6 affects the installation of the battery module 8, as Figures 1-2 shown, the connecting mechanism includes two symmetrically arranged clamping blocks 12. Through grooves are formed at the ends of the sliders 5. Moving plates 13 are slidably inserted through both sides of the through grooves. The other ends of the moving plates 13 are located in the through grooves and are fixedly connected to the clamping blocks 12. The side walls of the clamping blocks 12 are arranged in an inclined plane. Slots for inserting the sliders 5 are formed at the ends of the support beam 6. Card slots are formed on both sides of the inner walls of the slots. The clamping blocks 12 pass through the through holes and are inserted into the card slots. A spring 14 is fixedly arranged between the two moving plates 13.

[0032] When the battery module 8 to be installed has a large specification and the support beam 6 cannot be further moved, the two moving plates 13 can be pressed close to each other, and the spring 14 can be squeezed. At this time, the moving plates 13 drive the clamping blocks 12 to be pulled out from the inside of the card slots, so that the support beam 6 can be removed from the outside of the slider 5, thereby increasing the installation space of the battery module 8 inside the battery pack bottom case 1 and further improving the universality of use of the battery pack.

[0033] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
