[0001] The utility model belongs to the technical field of lithium batteries, and particularly relates to a structure of a all-solid-state lithium battery. Background Art

[0002] A solid-state lithium battery is a battery technology that uses solid electrodes and solid electrolytes. Compared with traditional liquid lithium batteries, it has a higher energy density and better safety. When the solid-state lithium battery is encapsulated and disassembled, since the battery packs are all buried inside the battery encapsulation structure and a large number of screws are required for fixation, the installation and disassembly are very inconvenient. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a structure of a all-solid-state lithium battery, so that the installation of the battery is relatively stable, the overall installation and disassembly work is also relatively convenient and fast, and fewer screws are used.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A structure of a all-solid-state lithium battery, including an encapsulation housing, an elevating support plate is arranged inside the encapsulation housing, a partition plate is also arranged inside the encapsulation housing, a guiding slide bar is fixedly arranged inside the encapsulation housing and a transmission screw rod is rotatably installed, the guiding slide bar penetrates through the elevating support plate and is slidably connected with it, the transmission screw rod penetrates through the elevating support plate and is threadedly connected with it, a top cover is arranged on the top of the encapsulation housing, an upper shock-absorbing buffer pad is arranged at the bottom of the top cover, a lower shock-absorbing buffer pad is installed on the top of the elevating support plate, an installation guide groove is installed on the top of the lower shock-absorbing buffer pad, a battery pack is slidably installed on the top of the installation guide groove, the battery pack includes a battery, a first docking seat is arranged at one end of the battery, a second docking seat is arranged at the other end of the battery, and a limiting plate is inserted inside the installation guide groove.

[0005] The beneficial effects of the present utility model are as follows: When the device is in use, a hexagonal wrench is connected to the hexagonal wrench connector, and the hexagonal wrench connector is rotated, thereby driving the transmission screw rod to rotate. Through the screw drive between the transmission screw rod and the lifting support plate, the lifting support plate rises under the guiding action of the guiding slide rod. After docking two adjacent batteries through the first docking seat and the second docking seat, they are slid into the installation guide groove at one time. Then, the limiting plate is inserted into the installation guide groove, and after comparing the screw holes of the two, the locking bolt is used to fix them between the two, which plays a limiting role for the battery pack. After the circuit connection is completed, the hexagonal wrench connector can be rotated in the reverse direction to reset the lifting support plate. Subsequently, the top cover is covered on the top of the encapsulation housing. After aligning the first screw connection plate and the second screw connection plate, the first screw connection plate and the second screw connection plate are fixed with screws to complete the installation of the device. The installation and wiring of the battery pack are mainly completed on the top of the encapsulation housing, and adjacent batteries are fixed through the first docking seat and the second docking seat. With the limiting and fixing effect of the installation guide groove on the battery and the blocking of the limiting plate, the installation of the battery is relatively stable, and the overall installation is also relatively convenient and fast, using fewer screws. When the battery needs to be disassembled or repaired in this device, the top cover is removed, and then the hexagonal wrench can be connected to the hexagonal wrench connector again. The hexagonal wrench connector and the transmission screw rod are rotated to drive the lifting support plate to rise. The locking bolt is unscrewed and the limiting plate is taken out, and then the battery pack can be pulled out along the installation guide groove, and each battery can be separated in turn, which greatly facilitates the disassembly of the battery.

[0006] For the fixation between the encapsulation housing and the top cover:

[0007] As a further improvement of the above technical solution: The side of the top of the encapsulation housing is provided with a first screw connection plate, and the outside of the top cover is provided with a second screw connection plate. The first screw connection plate and the second screw connection plate are connected by screws.

[0008] After the encapsulation housing and the top cover are aligned, the first screw connection plate and the second screw connection plate are fixed by screws.

[0009] For facilitating the rotation of the transmission screw rod:

[0010] As a further improvement of the above technical solution: The top end of the transmission screw rod is connected to the hexagonal wrench connector.

[0011] The beneficial effect of this improvement is that the hexagonal wrench connector is used to connect with the hexagonal wrench, and the transmission screw rod is rotated through the hexagonal wrench.

[0012] For playing a limiting role for the battery pack:

[0013] As a further improvement of the above technical solution: The installation guide groove and the limiting plate are both provided with screw holes and are fixed by locking bolts.

[0014] The beneficial effects of this improvement are as follows: After the installation guide groove and the limiting plate are inserted into each other, they are prevented from falling off by screwing the locking bolts, thereby playing a limiting role on the battery pack.

[0015] In order to conduct the heat generated by the battery:

[0016] As a further improvement of the above technical solution: The side of the encapsulation shell is provided with a through hole in a penetrating manner, and the bottom of the installation guide groove is provided with an air guide pipe.

[0017] The beneficial effects of this improvement are as follows: The cooperation of the air guide pipe and the through hole enables the external air flow to enter the interior of the encapsulation shell and enter the interior of the air guide pipe. The air guide pipe contacts the installation guide groove, and can conduct the heat generated by the battery, playing a role in heat dissipation.

A limiting plate 18 is inserted inside the installation guide groove 13.

[0030] It should be noted that the text seems to have some inaccuracies. It should be "a all-solid-state lithium battery structure" which is corrected to "an all-solid-state lithium battery structure" in the translation. Also, it is recommended to double-check the technical content for accuracy and consistency in a real patent context.When this device is in use, connect a hexagonal wrench to the hexagonal wrench connector 6 and rotate the hexagonal wrench connector 6, thereby driving the transmission screw 5 to rotate. Through the screw drive between the transmission screw 5 and the lifting support plate 2, the lifting support plate 2 is driven to rise under the guiding action of the guiding slide rod 4. After docking two adjacent batteries through the first docking seat 16 and the second docking seat 17, slide them into the installation guide groove 13 at one time, and insert the limiting plate 18 into the installation guide groove 13. After comparing the screw holes of the two, use the locking bolt 19 to fix them between the two, which plays a limiting role for the battery pack 14. After completing the circuit connection, the hexagonal wrench connector 6 can be rotated in the reverse direction to reset the lifting support plate 2. Subsequently, cover the top cover 9 on the top of the packaging shell 1. After aligning the first screw connection plate 8 and the second screw connection plate 11, use screws to fix between the first screw connection plate 8 and the second screw connection plate 11 to complete the installation of this device. The installation and wiring of the battery pack 14 are mainly completed on the top of the packaging shell 1. And the adjacent batteries 15 are fixed through the first docking seat 16 and the second docking seat 17. With the limiting and fixing effect of the installation guide groove 13 on the battery 15 and the blocking of the limiting plate 18, the installation of the battery 15 is relatively stable, and the overall installation is also relatively convenient and fast, using fewer screws. When the battery 15 needs to be disassembled or repaired in this device, remove the top cover 9, then connect the hexagonal wrench to the hexagonal wrench connector 6 again, rotate the hexagonal wrench connector 6, and the transmission screw 5 drives the lifting support plate 2 to rise. Unscrew the locking bolt 19 and take out the limiting plate 18, then the battery pack 14 can be pulled out along the installation guide groove 13, and each battery 15 can be separated in turn, which greatly facilitates the disassembly work of the battery 15.

[0031] A first screw connection plate 8 is provided on the side of the top of the packaging shell 1, and a second screw connection plate 11 is provided on the outside of the top cover 9. The first screw connection plate 8 and the second screw connection plate 11 are connected by screws.

[0035] Screw holes are provided on both the installation guide groove 13 and the limiting plate 18 and are fixed by the locking bolt 19.

[0036] After the installation guide groove 13 and the limiting plate 18 are inserted into each other, they are prevented from falling off by screwing the locking bolt 19, thereby playing a limiting role for the battery pack 14.

[0037] A through hole 7 is provided through the side surface of the encapsulation housing 1, and an air duct 20 is provided at the bottom of the installation guide groove 13.

[0038] The cooperation of the air duct 20 and the through hole 7 allows external air flow to enter the interior of the encapsulation housing 1 and enter the interior of the air duct 20. The air duct 20 contacts the installation guide groove 13, and can export the heat generated by the battery 15, playing a role in heat dissipation.

[0039] The working principle and usage process of the present utility model: When this device is in use, connect a hexagonal wrench to the hexagonal wrench connector 6, and rotate the hexagonal wrench connector 6, thereby driving the transmission screw rod 5 to rotate. Through the screw drive between the transmission screw rod 5 and the lifting support plate 2, drive the lifting support plate 2 to rise under the guiding action of the guiding slide rod 4. After docking two adjacent batteries through the first docking seat 16 and the second docking seat 17, slide them into the installation guide groove 13 at one time, and insert the limiting plate 18 into the installation guide groove 13. After comparing the screw holes of the two, use the locking bolt 19 to fix between the two, playing a role in limiting the battery pack 14. After completing the circuit connection, the hexagonal wrench connector 6 can be rotated in the reverse direction to reset the lifting support plate 2. Subsequently, cover the top cover 9 on the top of the encapsulation housing 1.

During the use process, through the setting of the upper shock-absorbing cushion 10 and the lower shock-absorbing cushion 12, it can play a role in shock absorption and buffering for the battery 15, avoiding hard collisions between the battery 15 and the surrounding structures. And the cooperation of the air duct 20 and the through hole 7 allows external air flow to enter the interior of the encapsulation housing 1 and enter the interior of the air duct 20. The air duct 20 contacts the installation guide groove 13, and can export the heat generated by the battery 15, playing a role in heat dissipation. When this device needs to disassemble the battery 15 or perform maintenance, remove the top cover 9, and then connect the hexagonal wrench to the hexagonal wrench connector 6 again. Rotate the hexagonal wrench connector 6 and the transmission screw rod 5 to drive the lifting support plate 2 to rise. Unscrew the locking bolt 19 and take out the limiting plate 18, then the battery pack 14 can be pulled out along the installation guide groove 13, and each battery 15 can be separated in sequence, greatly facilitating the disassembly work of the battery 15.
