Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0026] Depend on Figure 1 and Figure 2As shown, this is a schematic diagram of the battery cell fixing structure in this embodiment, including a left connecting plate 1, a right connecting plate 2, and a middle connecting member 3. The right connecting plate 2 is provided on the side of the left connecting plate 1. The middle connecting member 3 is installed between the left connecting plate 1 and the right connecting plate 2 to adjust the distance and size between the left connecting plate 1 and the right connecting plate 2. The middle connecting member 3 includes a splicing plate 31 and a limiting block 32. The splicing plate 31 is disposed between the left connecting plate 1 and the right connecting plate 2. The limiting block 32 is symmetrically fixed on both sides of the splicing plate 31. The left connecting plate 1 and the right connecting plate 2 are both provided with sliding grooves for sliding insertion with the limiting block 32.

[0027] During use, the splicing plate 31 of the corresponding size is selected according to the number and specifications of the battery cells. Then, with the cooperation of the limiting block 32, the splicing plate 31 is inserted between the left connecting plate 1 and the right connecting plate 2 to form a reinforcing frame for the battery cells. The limiting block 32 is convex in shape, which can prevent the middle connecting piece 3 from coming out between the left connecting plate 1 and the right connecting plate 2 after the left connecting plate 1, the right connecting plate 2 and the middle connecting piece 3 are combined, thus ensuring the stability of the equipment during use.

[0028] From the appendix Figure 3 As shown, it is a structural schematic diagram of the middle connector 3 in this embodiment. The middle connector 3 also includes a side baffle 33 and a side sliding block 34. The side baffle 33 is fixedly installed on the top of the splicing plate 31, and the side sliding block 34 is symmetrically installed on both sides of the side baffle 33. The side sliding block 34 is slidably connected to the left connecting plate 1 and the right connecting plate 2.

[0029] During use, by locking the position of the splicing plate 31, the side sliding block 34 is inserted into the left connecting plate 1 or the right connecting plate 2 on both sides to lock the position of the side baffle 33 itself. With the protective plates installed on the surfaces of the left connecting plate 1 and the right connecting plate 2, the side area of ​​the battery cell is protected to ensure the stability of the battery cell during use.

[0030] From the appendix Figure 2 As shown, the splicing plate 31 is provided with a battery cell positioning plate 4 for limiting the bottom of the battery cell. The battery cell positioning plate 4 has battery cell placement slots equidistantly opened inside. In use, the battery cell positioning plate 4 itself limits the bottom part of the battery cell, allowing the battery cell to be inserted into the placement slot of the battery cell positioning plate 4, thus assisting in the positioning of the battery cell.

[0031] From the appendix Figure 4As shown, this is a schematic diagram of the docking mechanism 5 in this embodiment. The battery cell fixing structure also includes the docking mechanism 5. The docking mechanism 5 is installed on the sides of the left connecting plate 1 and the right connecting plate 2. The docking mechanism 5 includes a plug-in block 51, a plug-in groove 52 and a snap-fit ​​component 53. The plug-in block 51 is symmetrically fixedly installed on the side of the left connecting plate 1. The right connecting plate 2 has a plug-in groove 52 for plugging into the plug-in block 51. The snap-fit ​​component 53 is installed on the side of the plug-in groove 52 inside the right connecting plate 2.

[0032] When it is necessary to connect the outer frame consisting of the left connecting plate 1, the right connecting plate 2 and the middle connecting piece 3 during use, insert the plug block 51 into the plug slot 52 inside another outer frame. By using the snap-fit ​​component 53, multiple outer frames can be stably spliced ​​together, and the connection of multiple battery cell groups can be completed quickly.

[0033] From the appendix Figure 5 As shown, it is a structural schematic diagram of the snap-fit ​​assembly 53 in this embodiment. The snap-fit ​​assembly 53 includes a movable groove 531, a locking block 532, and a spring assembly 534. The movable groove 531 is provided inside the right connecting plate 2 on the side of the insertion groove 52. The movable groove 531 communicates with the insertion groove 52. The locking block 532 is slidably installed inside the movable groove 531. The locking block 532 and the insertion block 51 are engaged and snapped together. A spring assembly 534 is installed at the end of the locking block 532.

[0034] During use, the plug-in block 51 is inserted into the plug-in block 51. At this time, the locking block 532 is squeezed and pushed by the plug-in block 51 and moves into the moving slot 531. At this time, the spring assembly 534 is in a charged state. When the plug-in block 51 is inserted into the target position, the locking block 532 automatically pops out due to the elastic force of the spring assembly 534 and completes the locking with the plug-in block 51, realizing the combination and docking of multiple sets of outer frames.

[0035] From the appendix Figure 5 As shown, it is a structural schematic diagram of the snap-fit ​​component 53 in this embodiment. The snap-fit ​​component 53 also includes a push rod 533, which is fixedly installed on the side of the snap-fit ​​block 532 and is slidably connected to the right connecting plate 2.

[0036] During use, by pushing the push rod 533, the push rod 533 causes the locking block 532 to slide stably inside the moving groove 531, releasing the locking block 532 from the plug-in block 51, and quickly completing the disassembly of the outer frame.

[0037] From the appendix Figure 5As shown, it is a structural schematic diagram of the snap-fit ​​component 53 in this embodiment. The lower surface of the right connecting plate 2 is provided with a sliding groove that cooperates with the sliding of the push rod 533. The lower surface of the right connecting plate 2 is provided with a toggle groove outside the sliding groove to facilitate the toggle of the push rod 533. With the opening of the toggle groove and the sliding groove, the user can manually push the push rod 533 to stably release the snap-fit ​​between the snap-fit ​​block 532 and the plug-in block 51.
