[0025] As Figure 3As shown, each of the locking devices 4 comprises a lifting driving assembly 12, a sliding assembly 13, a clamping assembly 14 and a reset device 15; the lifting driving assembly 12 is arranged in the battery cell accommodating cavity 5, the reset device 15 is arranged on the side of the lifting driving device 12 close to the liquid cooling plate 3, and the reset device 15 is used to provide a restoring force when the battery cell is removed, so as to ensure that the lifting driving assembly 12 is automatically reset. A plurality of sliding assemblies 13 are respectively arranged in the respective corresponding locking driving cavities 16, and a plurality of driving ends of the lifting driving assembly 12 are respectively in the respective corresponding locking driving cavities 16 and are drivingly connected with the respective corresponding sliding assemblies 13, and a plurality of clamping assemblies 14 are respectively drivingly connected with the respective corresponding sliding assemblies 13; when the battery cell is placed in the battery cell accommodating cavity 5, the lifting driving assembly 12 drives the sliding assembly 13 to slide forward under the action of the gravity of the battery cell, the forward sliding refers to the driving sliding block 21 moving towards the battery cell, so as to realize the clamping action; thereby driving the clamping assembly 14 to clamp the battery cell; when the battery cell is taken out of the battery cell accommodating cavity 5, the reset device 15 drives the lifting driving assembly 12 to reset, thereby driving the sliding assembly 13 to slide reversely, thereby driving the clamping assembly 14 to separate from the battery cell; the reverse sliding refers to the driving sliding block 21 moving away from the battery cell, so as to release the clamping state, and ensure that the battery cell is easily taken out.

[0026] The reset device 15 is a compression spring, one end of the reset device 15 abuts against the upper surface of the liquid cooling plate 3, and the other end abuts against the bottom surface center of the lifting block 17; when the lifting block 17 is pressed down by the gravity of the battery cell, the reset device 15 stores energy, and after the battery cell is taken out of the battery cell accommodating cavity 5, the reset device 15 releases energy to push the lifting block 17 to reset.

[0027] As shown in Figure 3 and 4 The lifting driving assembly 12 comprises a lifting block 17, a first connecting rod 18 and a second connecting rod 19; the lifting block 17 is located at the center of the battery cell accommodating cavity 5, and the reset device 15 is installed at the center of the side of the lifting block 17 close to the liquid cooling plate 3; the two first connecting rods 18 are arranged in parallel with the cross beam 11, and the ends of the two first connecting rods 18 close to each other are evenly hinged on the two sides of the lifting block 17 along the length direction of the cross beam 11, and the ends away from each other are respectively located in the respective corresponding locking driving cavities 16 and are drivingly connected with the respective corresponding sliding assemblies 13; the first connecting rod 18 and the second connecting rod 19 convert the vertical movement of the lifting block 17 into the linear sliding of the driving sliding block 21, so as to realize force transmission and direction conversion; the two second connecting rods 19 are arranged perpendicularly to the cross beam 11, and the ends of the two second connecting rods 19 close to each other are respectively hinged on the two sides of the lifting block 17 perpendicular to the length direction of the cross beam 11; the ends away from each other are respectively located in the respective corresponding locking driving cavities 16 and are drivingly connected with the respective corresponding sliding assemblies 13.

[0028] As Figure 4 and 5 shown, each of the sliding assembly 13 includes a guide rail 20 and a drive slider 21, the guide rail 20 is fixed in the locking drive cavity 16, the drive slider 21 is in sliding fit with the guide rail 20, each of the drive slider 21 is respectively hinged with one end of the first connecting rod 18 or the second connecting rod 19 corresponding to each other in the locking drive cavity 16; when the battery is placed or taken out of the battery containing cavity 5, one end of each of the first connecting rod 18 and the second connecting rod 19 in the locking drive cavity 16 will synchronously drive each corresponding drive slider 21 to slide away from or close to the battery containing cavity 5 relative to each corresponding guide rail 20, thereby ensuring that all clamping assemblies 14 work together to avoid the battery from shifting in the containing cavity 5.

[0029] As Figure 4 and 5 shown, each of the clamping assembly 14 includes a drive gear plate 22, a driven gear 23, a locking rack 24 and a support frame 25; the drive gear plate 22 is fixedly connected on the side of the drive slider 21 away from the cross beam 11, the support frame 25 is fixed on the upper surface of the end of the guide rail 20 away from the cross beam 11, the driven gear 23 is in rotary fit on the support frame 25 and is in meshing arrangement with the drive gear plate 22; the locking rack 24 is in sliding fit with the end of the support frame 25 away from the guide rail 20 and is in meshing arrangement with the driven gear 23; when the drive slider 21 slides relative to the guide rail 20, the drive gear plate 22 moves synchronously with the drive slider 21, thereby driving the driven gear 23 to rotate, under the meshing effect, the locking rack 24 moves synchronously in the direction opposite to the movement direction of the drive gear plate 22; thereby realizing the locking of the locking rack 24 to the battery or separating from the battery, thereby converting the horizontal sliding of the drive slider 21 into the vertical or horizontal movement of the locking rack 24, depending on the meshing direction of the gear, to complete the locking or releasing action; more specifically, the end of the locking rack 24 close to the cross beam 11 is the locking end, the cross section shape of the locking end is rectangular, the segment of the locking rack 24 away from the cross beam is the meshing end, which is a toothed plate in meshing arrangement with the driven gear 23.

[0030] The support frame 25 is provided with a guide block 26, and the locking rack 24 is provided with a sliding groove 27 through the two sides in the length direction, the guide block 26 can guide the sliding of the locking rack 24 and form stable support for the locking rack 24; the cooperation of the guide block 26 and the sliding groove 27 enhances the movement stability of the locking rack 24 and prevents jamming.

[0031] Due to the presence of the locking device 4, the bottom of the battery cell accommodating cavity 5 is not flat. If the battery cell is directly placed into the battery cell accommodating cavity 5, the battery cell will collide with the protruding point in the battery cell accommodating cavity 5 in the event of an accident such as a collision, thereby causing the local impact force on the battery cell to be too large, and there is a risk that the battery cell will be pierced. Therefore, a protection structure needs to be designed. The protection structure aims to disperse the impact force and provide a flat support surface to reduce the risk of damage to the battery cell.

[0032] As shown in Figure 1 and 3 In the present application, an electric cell tray 29 and a uniform force plate 30 are also included. The electric cell tray 29 is detachably installed in the battery cell accommodating cavity 5, and the outer wall of the electric cell tray 29 is arranged in close contact with the cavity wall of the battery cell accommodating cavity 5. When the battery cell is placed in the battery cell accommodating cavity 5, the inner wall of the electric cell tray 29 surrounds the outer wall of the battery cell. The electric cell tray 29 provides direct support and isolation for the battery cell, preventing it from contacting the protruding point on the bottom. The surface of the uniform force plate 30 in contact with the electric cell tray 29 is a flat structure. The uniform force plate 30 is fixedly arranged on the side of the lifting block 17 away from the liquid cooling plate 3, and the end of the uniform force plate 30 is in sliding fit with the cavity wall of the battery cell accommodating cavity 5. When the battery cell is placed in the battery cell accommodating cavity 5, the side of the uniform force plate 30 away from the liquid cooling plate 3 is in contact with the bottom surface of the electric cell tray 29. The uniform force plate 30 moves with the lifting block 17, and through contact with the electric cell tray 29, the weight of the battery cell is evenly transmitted to the lifting block 17, preventing local stress concentration.

[0033] A plurality of locking holes are formed on the circumferential surface of the lower end of the battery cell corresponding to the locking rack 24. A plurality of lock tongue through holes 31 are formed on the peripheral blocking wall of the electric cell tray 29 corresponding to the locking holes. Each locking rack 24 corresponds to a corresponding locking hole position one by one. The "lock tongue" in the lock tongue through hole 31 refers to the locking end of the locking rack 24. The locking end of the locking rack 24 directly acts on the locking hole of the battery cell to achieve reliable fixation of the battery cell. When the battery cell is placed in the battery cell accommodating cavity 5, the locking end of each locking rack 24 is locked in the corresponding locking hole through the lock tongue through hole 31. When the battery cell needs to be taken out of the battery cell accommodating cavity 5, each locking rack 24 is retracted into the locking drive cavity 16 under the drive of the driven gear 23

[0034] The electric cell tray 29 is provided with a second sealing ring 28 on the side close to the upper cover 2. When the liquid cooling plate 3 and the upper cover 2 are tightly connected together through fasteners, the battery cell accommodating space 5 can be isolated from the outside through the first sealing ring 6 and the second sealing ring 28, thereby improving the waterproofness of the entire battery.

[0035] The above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can also make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
