For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Reference Figures 1-3 According to an embodiment of the lithium battery module end cap of this utility model, it includes a plate body 11, on which a downwardly extending mounting plate 12 is integrally formed, and the mounting plate 12 is provided with mounting holes. When installing, the worker can fix the lithium battery module end cap to the base containing the battery with fasteners such as bolts to complete the installation and form a lithium battery module. In addition, in order to facilitate the worker to carry the lithium battery module, a grip component is also included. The grip component includes two mounting blocks 13 and a flexible strip 14 installed between the two mounting blocks 13. The user or worker can lift the flexible strip 14.

[0029] To facilitate the assembly and disassembly of the mounting block 13, the plate body 11 has two through slots 15 that extend vertically to accommodate the mounting block 13. The mounting block 13 includes a housing 21, and the housing 21 has a vertically extending mounting groove 22. A vertical plate 23 is slidably connected to the mounting groove 22, and a horizontally extending locking plate 24 is integrally formed at the lower end of the vertical plate 23. The left and right width of the locking plate 24 is not greater than the left and right width of the through slot 15, so that the locking plate 24 can pass upward through the through slot 15 and leave. In addition, a positioning mechanism is included to control the left and right position of the vertical plate 23.

[0030] In this embodiment, the positioning mechanism includes a spring connected between the side of the mounting groove 22 and the side of the vertical plate 23. A pressing block 25 is also slidably connected in the mounting groove 22. The lower side of the pressing block 25 is an inclined surface adapted to the upper side of the vertical plate 23. The mechanism also includes a pin 26 that penetrates the outer shell 21 and is inserted into the pressing block 25. When the pressing block 25 is pressed down, it will push the vertical plate 23 and the locking plate 24 to move laterally, so that the locking plate 24 can be attached to the bottom surface of the plate 11. At this time, the outer shell 21 will be fixed in the through groove 15, and the pin 26 can be inserted into the pressing block 25 and limit its vertical position.

[0031] In a second embodiment of the lithium battery module end cover, in order to facilitate the disassembly and assembly of the flexible strip 14, an opening groove 27 is provided in the side of the mounting groove 22, and the two mounting blocks 13 are arranged symmetrically on the left and right so that the two opening grooves 27 are close to each other. The pressing block 25 is also provided with a locking mechanism for locking the flexible strip 14.

[0032] The locking mechanism includes slots 28 that extend vertically through the left and right sides of the flexible strip 14. The pressing block 25 has a notch 29 on its side, and the upper side of the notch 29 is integrally formed with a vertical plate 30 that can be inserted into the slot 28. When the pressing block 25 is on the upper side, the flexible strip 14 can be inserted horizontally into the notch 29. Then, when the pressing block 25 moves downward, the vertical plate 30 will be inserted into the notch 29 and lock the flexible strip 14.

[0033] Furthermore, the removed flexible strip 14 can cover the through groove 15. There are two flexible strips 14 distributed front and back. Each pressing block 25 is provided with two vertical plates 30 distributed front and back. The upper side of the plate body 11 on both the front and back sides of each through groove 15 is provided with a Velcro surface. The flexible strip 14 is provided with two Velcro hook surfaces. And the width of each flexible strip 14 is not less than the left and right width of the through groove 15.

[0034] The lower side of the plate 11 is provided with two abutment brackets 31 distributed on the left and right, and the abutment brackets 31 are used to support the locking plate 24.

[0035] When the gripping assembly needs to be installed, the operator inserts the two outer shells 21 into the two through slots 15 respectively, so that the vertical plate 23 and the locking plate 24 press against the abutment frame 31. Then, the operator inserts the flexible strip 14 into the notch 29 in the two pressing blocks 25. Then, the operator presses down on the pressing block 25. When the pressing block 25 moves downward, the two locking plates 24 will move away from each other and stick to the bottom surface of the plate body 11. At the same time, the vertical plate 30 can be inserted into the slot 28 and lock the left and right positions of the flexible strip 14. When the pressing block 25 moves to the lowest side, the pin 26 can be inserted into the pressing block 25 and lock the up and down positions of the pressing block 25. At this time, the operator can lift the flexible strip 14 and raise the lithium battery module.

[0036] When the outer casing 21 needs to be removed, the worker first pulls out the pin 26. At this time, under the action of the spring, the two vertical plates 23 move closer to each other, and the outer casing 21 moves upward away from the through groove 15. At the same time, the flexible strip 14 is no longer locked by the vertical plate 30, and the flexible strip 14 can be removed separately. Then, the worker can place the flexible strip 14 back and forth and fix the flexible strip 14 on the plate 11 and cover the through groove 15 by using the hook and loop sides of the Velcro and the loop side of the Velcro. This prevents foreign objects from falling into the lithium battery module through the through groove 15 when the lithium battery module end cover is in the installation state, and also facilitates pressure relief in case of thermal runaway of the lithium battery.

[0037] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
