DETAILED DESCRIPTION

[0022] like Figures 1-6As shown, the utility model provides a technical solution: a lithium battery shell that can resist falling, including a shell body 1, a cover body 2 connected to the surface of the shell body 1, a foam board 3 fixed to the inner wall of the shell body 1, a lithium battery pack 4 placed inside the foam board 3, and a docking assembly 5 for stacking is provided on the surface of the shell body 1 and the cover body 2. The docking assembly 5 includes a fixing column 50 fixed to the bottom of the shell body 1, a card slot 51 is opened on the surface of the fixing column 50, a docking groove 52 is opened on the top of the cover body 2, and a cavity 53 is opened inside the cover body 2. Component 5 also includes a limit block 54, which is slidably connected to the inner wall of the cavity 53. The limit block 54 passes through the docking groove 52. A spring 57 is fixed to the end of the limit block 54 away from the docking groove 52. The end of the spring 57 away from the limit block 54 is fixed to the inner wall of the cavity 53. The inner wall of the cavity 53 is slidably connected to a slider 56. The surface of the limit block 54 is hinged with a linkage plate 55. The end of the linkage plate 55 away from the limit block 54 is hinged to the surface of the slider 56. The docking assembly 5 also includes a linkage 58, which includes a knob 580. The knob 580 The surface of the cover 2 is rotatably connected, and the output shaft of the knob 580 passes through the cavity 53. A worm 581 is fixed to the surface of the output shaft of the knob 580. A worm gear 582 is rotatably connected to the inner wall of the cavity 53. The worm gear 582 meshes with the worm 581. A gear 583 is fixed to the bottom of the worm gear 582. A fixing plate 584 is fixed to the inner wall of the cavity 53. A rack 585 is slidably connected to the surface of the fixing plate 584. The rack 585 meshes with the gear 583. A connecting plate 586 is fixed to the surface of the rack 585. A contact plate 587 is fixed to the top of the slider 56. The fixed column 50 is inserted into the docking groove 52, and the limit block 54 enters the card slot 51, and the outer shell body 1 is limited and stable, and will not slip during transportation, avoiding damage. Turn the knob 580 forward, and the worm 581 drives the worm wheel 582 and the gear 583 to rotate. The gear 583 drives the rack 585 and the connecting plate 586 to move. The surface of the connecting plate 586 contacts the surface of the contact plate 587, driving the slider 56 to move, and the limit block 54 is pulled out of the card slot 51 through the linkage plate 55. At this time, the outer shell body 1 and the cover body 2 can be separated normally.

[0023] The surface of one end of the limit block 54 away from the spring 57 is set to be inclined. When it is interfered with, the limit block 54 can be moved to facilitate stacking. There are two groups of limit blocks 54, springs 57, and linkage plates 55, and the two groups of limit blocks 54, springs 57, and linkage plates 55 are symmetrically arranged with the center line of the slider 56 as the symmetry axis, which improves the stability of stacking. The fixed column 50 is consistent in shape with the docking groove 52, which facilitates the fixed column 50 to enter the docking groove 52 for limiting.

[0024] When the shell body 1 needs to be stacked, the fixing column 50 is inserted into the docking groove 52. At this time, the surface of the fixing column 50 contacts the inclined surface of the limit block 54. At this time, the limit block 54 moves away from the docking groove 52, synchronously driving the linkage plate 55 to flip, and then pulling the slider 56 to move synchronously. The linkage plate 55 and the slider 56 can make the two sets of limit blocks 54 move synchronously. When the limit block 54 moves away from the docking groove 52, the spring 57 is compressed. When the limit block 54 is parallel to the position of the card slot 51, the spring 57 is released, and the limit block 54 enters the card slot 51, which can make the shell bodies 1 limited and stable, and will not slip during transportation, avoiding damage. When separation is required, the knob 580 is turned forward, and the worm 581 drives The worm gear 582 and the gear 583 rotate, and the gear 583 drives the rack 585 and the connecting plate 586 to move. The surface of the connecting plate 586 contacts the surface of the contact plate 587, driving the slider 56 to move, and the limit block 54 is pulled out of the slot 51 through the linkage plate 55. At this time, the outer shell body 1 and the cover body 2 can be separated normally. At the same time, the outer shell body 1 and the foam plate 3 are set. The outer shell body 1 is made of engineering plastic. When the outer shell body 1 falls, it can absorb and disperse the impact force and reduce the damage to the internal battery. At the same time, the foam plate 3 is set, which can further absorb energy to avoid damage to the internal lithium battery pack 4. Reverse the knob 580, and the spring 57 can drive the limit block 54, the linkage plate 55, the slider 56, and the contact plate 587 to reset.

[0025] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
