[0026] The present invention provides a technical solution:

[0027] Embodiment 1

[0028] Combined with Figures 1 to 4 , a convenient and assembled safe lithium battery includes an outer shell 3, an installation mechanism 1 is arranged inside the outer shell 3, a battery body 4 is arranged inside the installation mechanism 1, and a fixing mechanism 2 is arranged inside the top of the outer shell 3.

[0029] The installation mechanism 1 includes a placement component 11 and a support component 12. The placement component 11 is arranged on the left and right sides inside the outer shell 3, and the support component 12 is arranged at the bottom inside the outer shell 3.

[0030] The placement component 11 includes a sieve plate 1101, the sieve plate 1101 is fixedly connected to the inner sides of the front and rear of the outer shell 3, four corners inside the outer shell 3 are fixedly connected with clamping partitions 1102, the clamping partitions 1102 are clamped to the four corners outside the battery body 4, the front and rear sides inside the clamping partitions 1102 are fixedly connected with fixing shafts 1103, the outer circle of the fixing shaft 1103 is rotatably connected with a transmission roller 1104, and the inner side of the outer circle of the transmission roller 1104 is in contact with the left and right sides of the battery body 4. The support component 12 includes a fixed cylinder 1201, the fixed cylinder 1201 is fixedly connected to the inner bottom of the outer shell 3, a sliding ring 1202 is slidably connected inside the fixed cylinder 1201, the inner circle of the sliding ring 1202 is fixedly connected with a telescopic cylinder 1203, the top of the telescopic cylinder 1203 is in contact with the bottom of the battery body 4, the telescopic cylinder 1203 is slidably connected to the inner top of the fixed cylinder 1201, and a compression spring 1204 is fixedly connected to the inner top of the telescopic cylinder 1203, and the compression spring 1204 is fixedly connected to the inner bottom of the outer shell 3.

[0031] Further: When the staff disassembles and assembles the battery body 4, the clamping partition 1102 limits the position of the battery body 4, so that it can keep itself positioned in the middle of the outer shell 3 and maintain an appropriate distance from the inner wall of the outer shell 3, ensuring the circulation of the space inside the outer shell 3, enabling the air inside the outer shell 3 to communicate with the outside through the sieve plate 1101. At the same time, the setting of the transmission roller 1104 contacts the left and right sides of the battery body 4 during the disassembly and assembly of the battery body 4, guiding the movement of the battery body 4 during the disassembly and assembly process of the battery body 4, increasing the fluidity during the disassembly and assembly process of the battery body 4, facilitating the staff to disassemble and assemble the battery body 4, and the telescopic cylinder 1203 is arranged at the inner bottom of the outer shell 3 to support and buffer the bottom of the battery body 4 through the compression spring 1204, so that the battery body 4 will not collide with the inner bottom of the outer shell 3 during the installation process, increasing the stability during the installation process of the battery body 4.

[0032] Embodiment 2

[0033] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 ,and on the basis of Embodiment 1, it is further obtained that the fixing mechanism 2 includes a closing component 21, a positioning component 22 and a pulling component 23. The closing component 21 is arranged inside the top of the outer shell 3, the positioning component 22 is arranged on the left and right sides inside the top of the closing component 21, and the pulling component 23 is arranged on the front and rear sides of the positioning component 22.

[0034] The closing assembly 21 includes a closing cover 2101, which is snap-fitted inside the top of the housing 3. On the front and rear sides inside the top of the closing cover 2101, there are fixedly connected grips 2102. At the bottom of the grips 2102, there is fixedly connected a reinforcing rod 2103, and the reinforcing rod 2103 is fixedly connected to the bottom inside the top of the closing cover 2101. At the bottom of the closing cover 2101, there is fixedly connected a positioning latch 2104. An outer ring of the positioning latch 2104 is sleeved with a support cushion block 2105, and the support cushion block 2105 is fixedly connected to the four inner corners of the housing 3. The top of the support cushion block 2105 is in contact with the bottom of the closing cover 2101. The positioning assembly 22 includes a fixed box 2201, and the fixed box 2201 is fixedly connected to the left and right sides inside the top of the closing cover 2101. Inside the fixed box 2201, there is a slidably connected sliding cylinder 2202. Inside the sliding cylinder 2202, there is fixedly connected a return spring 2203. On the outer side of the sliding cylinder 2202, there is fixedly connected a positioning card plate 2204, and the positioning card plate 2204 is snap-fitted inside the left and right sides of the closing cover 2101 and the housing 3. The pulling assembly 23 includes a moving slide bar 2301, and the moving slide bar 2301 is fixedly connected to the front and rear sides of the sliding cylinder 2202. The moving slide bar 2301 is slidably connected to the front and rear sides inside the fixed box 2201. An outer ring of the moving slide bar 2301 is rotatably connected with a rotating ring 2302. On the outer ring of the rotating ring 2302, there is fixedly connected a pull rod 2303. An outer side of the pull rod 2303 is sleeved with a positioning bracket 2304, and the positioning bracket 2304 is fixedly connected to the position inside the top of the closing cover 2101 and on the inner side of the fixed box 2201.

[0035] Furthermore: The staff only needs to pull the pull rod 2303 to drive the movement of the positioning card plate 2204 to complete the disassembly and assembly process of the closing cover 2101, which is convenient for the staff to disassemble and assemble the closing cover 2101, enabling the staff to quickly complete the disassembly, assembly or replacement process of the battery main body 4 inside the housing 3, and the operation is simple and convenient for the staff to use.

[0036] During the actual operation process, when this device is in use and the battery body 4 needs to be disassembled, the staff first pulls the pull rod 2303 to move inward. The inward movement of the pull rod 2303 drives the moving slide rod 2301 to move through the rotating ring 2302. The movement of the moving slide rod 2301 drives the positioning clamping plate 2204 to retract inward into the fixed box 2201 through the sliding cylinder 2202, so that the positioning clamping plate 2204 releases the connection with the closing cover 2101 and the outer shell 3. At the same time, after the pull rod 2303 moves inward to the inner side position of the positioning frame 2304, the staff then flips the pull rod 2303 downward. After that, the staff releases the pulling of the pull rod 2303 on this side. Then, the sliding cylinder 2202 drives the pull rod 2303 to move outward under the action of the return spring 2203. Since the pull rod 2303 is located at the inner side position of the positioning frame 2304 at this time, the pull rod 2303 is clamped to the inner top of the positioning frame 2304 during the outward movement to complete the positioning of the positioning clamping plate 2204. Then, the above operation is repeated to also clamp the pull rod 2303 on the other side to the positioning frame 2304, so that the positioning clamping plate 2204 on the other side retracts into the fixed box 2201. Then, the staff only needs to pull the handle 2102 upward to drive the closing cover 2101 upward to complete the disassembly of the closing cover 2101. After that, the staff can move the battery body 4 upward to complete the disassembly process of the battery body 4.
