[0024] like Figures 1 to 4As shown in the figure, a lithium battery structure that is convenient for quick replacement includes an installation housing 1 and a lithium battery body 2. Inside the installation housing 1, "U"-shaped limit blocks 3 for limiting and fixing the lithium battery body 2 are symmetrically arranged front and back. On the inner wall surface of the installation housing 1, there is a side fixing part 4 for adjusting the distance between the two limit blocks 3. Four support blocks 10 are mortise-connected to the upper surface of the installation housing 1. The support blocks 10 are tubular with a square outside and a round inside. A cross bar 9 is rotatably connected between two symmetrically arranged support blocks 10 on the left and right. Above the lithium battery body 2, there is a support rod 5. On the outer wall surface of the cross bar 9, there is a lifting part 7 for driving the support rod 5 to move up and down. A telescopic column 6 is detachably connected between two symmetrically arranged support rods 5 front and back. On the side wall surface of the installation housing 1, there is a linkage rotation part 8 for driving the two cross bars 9 to rotate;

[0025] Specifically, the limit blocks 3 can fix both sides of the lithium battery body 2. The side fixing part 4 can adjust the distance between the two corresponding limit blocks 3 front and back according to the different sizes of the lithium battery body 2, so as to fix lithium battery bodies 2 of various specifications, enhancing practicality. The support rods 5 can press and limit the upper part of the lithium battery body 2. The lifting part 7 can drive multiple support rods 5 to move up and down when the cross bar 9 rotates, effectively improving the stability of the installation of the lithium battery body 2 in the inner cavity of the installation housing 1. At the same time, it is also convenient to disassemble and replace a certain component when it fails, effectively reducing economic losses compared with replacing the entire component, and also reducing the difficulty of replacing the lithium battery body 2.

[0026] As Figure 2 shown, the side fixing part 4 includes balls 401. Balls 401 are rotatably connected to both the inner wall surface of the installation housing 1 and the outer wall surface of the limit block 3. A damping spring 402 and a telescopic rod 403 are welded between the two balls 401. The telescopic rod 403 is surrounded by the damping spring 402;

[0027] Specifically, through the damping spring 402 and the telescopic rod 403 provided, they can expand and contract correspondingly according to the specifications of the lithium battery body 2, so as to adapt to lithium battery bodies 2 of different sizes, enhancing the practicality of the product.

[0028] As Figure 2 shown, a chute 404 is opened on the inner wall surface of the limit block 3. Inside the chute 404, a plurality of vertically equally spaced extrusion rollers 405 are rotatably connected. The extrusion rollers 405 are made of flexible plastic or silicone;

[0029] Specifically, the extrusion roller 405 is arranged to rotate accordingly when the lithium battery body 2 is inserted downward between the two limit blocks 3, so that the lithium battery body 2 can be smoothly installed between the two limit blocks 3. At the same time, the extrusion roller 405 made of flexible plastic or silicone material can avoid scratching and wearing the lithium battery body 2, thereby ensuring the safety of the lithium battery body 2, and also can enhance the stability of the lithium battery body 2 installed inside the limit blocks 3.

[0030] like Figure 3 As shown, the lifting part 7 includes a gear 701, and the outer wall surface of the cross bar 9 is sleeved with a plurality of gears 701 corresponding to the support rod 5. A rack 702 meshing with the gear 701 is slidably connected to the mounting housing 1, and the upper end of the rack 702 is connected to the side wall of the support rod 5 by a mortise and tenon process. The length of the cross bar 9 of the lifting part 7 and the lithium battery body 2 is twice the height of the lithium battery body 2;

[0031] Specifically, the rack 702 is arranged to rotate accordingly when the cross bar 9 rotates. When the rack 702 rotates, it can drive the rack 702 to move up and down. When the rack 702 rotates clockwise, it drives the rack 702 to move vertically downward, and can press down and fix the lithium battery body 2 installed in the inner cavity of the installation shell 1. When the rack 702 rotates counterclockwise, it drives the rack 702 to move vertically upward, and can take out the lithium battery body 2 installed in the inner cavity of the installation shell 1. The structure is simple and easy to operate.

[0032] like Figure 4 As shown, the linkage rotating part 8 includes a second gear 801, the input end of the crossbar 9 is connected to the second gear 801, the side wall surface of the mounting housing 1 is provided with a third gear 804 meshing with the second gear 801, and the side wall surface of the mounting housing 1 is provided with a motor 802 for driving the third gear 804;

[0033] Specifically, the motor 802 is configured to drive the pulley 803 to rotate, which can drive the gear 2 801 to rotate accordingly, thereby driving the cross bar 9 to rotate, thereby achieving the purpose of pressing down and fixing the lithium battery body 2.

[0034] like Figure 4 As shown, the output end of the motor 802 is connected to a pulley 803 whose outer wall is fixedly connected to the gear three 804, and a connecting belt 805 is wound between the front and rear pulleys 803;

[0035] Specifically, by setting up a connecting belt 805, one of the motors 802 can be driven, so that when the pulley 803 at the output end of the motor 802 rotates, the other pulley 803 can be driven to rotate, thereby achieving that driving one pulley 803 can drive the two cross bars 9 to rotate synchronously, effectively saving power costs.

[0036] In summary: the limit blocks 3 are provided to fix the two sides of the lithium battery body 2, and the side fixing parts 4 are provided to adjust the distance between the two corresponding limit blocks 3 at the front and rear according to the different sizes of the lithium battery body 2, so as to fix the lithium battery bodies 2 of various specifications and enhance practicality; the support rods 5 are provided to press down and limit the upper part of the lithium battery body 2, and the lifting parts 7 are provided to drive multiple support rods 5 to move up and down when the cross bar 9 rotates, which effectively improves the stability of the installation of the lithium battery body 2 and the inner cavity of the installation shell 1, and also facilitates the disassembly and replacement of a component when it is damaged. Compared with the replacement of the entire component, it effectively reduces the economic loss and also reduces the difficulty of replacing the lithium battery body 2.
