[0007] The present invention is further configured such that buckle grooves are continuously and equidistantly arranged on the side wall of the shell, and the buckle grooves are matched with protrusions on a side surface of the embedding component.

[0008] The present invention is further configured such that the opposite surface of the raised side of the insert one is a flat plate, and the flat surface of the insert one fits with the battery cell body, and the raised surface of the added insert one fits with the flat surface of the original insert one.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiments

[0020] See also Figure 1-4 The present invention is an adjustable lithium battery cell structure, including an integrated lithium battery cell; the integrated lithium battery cell includes a shell 1, a protective corner 2 integrally arranged at the corner of the shell 1, a heat dissipation groove 3 equidistantly and continuously opened at the bottom of the shell 1, an end cover 6 sealed at the opening of the shell 1, a terminal 10 embedded at the corner of the end cover 6, an adjustment knob 7 arranged in the middle position of the end cover 6, an insert 13 and an insert 2 14 embedded in the shell 1, and a battery body 12 arranged between the insert 13 and the insert 2 14.

[0021] Specifically, in the lithium battery cell structure involved in the present application, an integrated lithium battery cell is provided to replace the current bulk cell structure, so as to facilitate the connection and use of the cell. At the same time, the number of installed cell bodies 12 built into the shell 1 can be adjusted according to actual usage requirements to meet the centralized installation requirements of different numbers of cell bodies 12. Both the insert 13 and the insert 2 14 serve as auxiliary fixing structures, which are inserted and embedded between the cell body 12 and the shell 1 to limit the position of the cell body 12 so that it maintains a fixed relative position with the shell 1. When the insert 13 and the insert 2 14 limit the cell body 12, the number of inserts 13 and 14 to be installed is selected according to the size of the cell body 12 to meet the installation requirements of cell bodies 12 of different sizes.

[0022] After the assembly of several of the battery cell bodies 12 is completed, the connecting circuit is connected to the terminal 10 and the adjustment knob 7 (the terminal 10 is used to connect the integrated lithium battery cell with the external circuit, and the adjustment knob 7 is used to control the output voltage of the integrated lithium battery cell. The use of the above-mentioned structure is currently a relatively conventional and mature technology, and this application does not make further restrictive descriptions of its principles). Finally, the end cover 6 is sealed and installed with the opening of the shell 1 to complete the assembly of the integrated lithium battery cell.

[0023] Furthermore, a mounting groove 11 is recessed on the bottom side of the shell 1 , an inner protrusion of the positioning plate 4 is fixed inside the mounting groove 11 , and a connecting ear seat 5 is fixed on the outer side of the positioning plate 4 .

[0024] Specifically, the positioning plate 4 is an external connecting member, and after the ear seat 5 fixed on its outer side is fixed to the outer mounting surface by a bolt structure, the position of the shell 1 is fixed under the connecting action of the positioning plate 4, so that the position of the integrated lithium battery cell is fixed.

[0025] Furthermore, a trapezoidal protrusion 8 is symmetrically arranged in the middle of the end cover 6 , and a handle 9 is buckled on the outside of the trapezoidal protrusion 8 , and the handle 9 is movably buckled in a recessed area symmetrically arranged in the middle of the end cover 6 .

[0026] Specifically, the handle 9 is provided to facilitate the movement and carrying of the integrated lithium battery cell. When in use, the handle 9 can be pulled out from the recessed area of ​​the end cover 6. When not in use, the handle 9 can be stored in the corresponding recessed area.

[0027] Furthermore, the shell 1 is an integrally formed structure, the battery cell body 12 is centrally arranged inside the shell 1 , and the bottom of the battery cell body 12 is in contact with the heat dissipation area at the bottom of the shell 1 .

[0028] Specifically, the one-piece molded shell 1 has high stability and is easy to install. It is used for centralized installation of the battery cell body 12 and external protection of the battery cell body 12. The heat generated by the battery cell body 12 during operation is mainly discharged from the bottom heat dissipation area of ​​the shell 1, and its heat dissipation area corresponds to the heat dissipation groove 3 outside the shell 1. Specific embodiments

[0029] See also Figure 3 and Figure 4 On the basis of the specific embodiment one, the opposite surface of the raised side of the embedding part 13 is set as a flat plate, and the flat surface of the embedding part 13 is in contact with the battery cell body 12, and the raised surface of the added embedding part 13 is in contact with the flat surface of the original embedding part 13; the embedding part 2 14 is continuously and equidistantly provided with protrusions on both sides, and the end of the embedding part 2 14 is in contact with the flat surface of the embedding part 13.

[0030] Specifically, the first insert 13 and the second insert 14 are both used as auxiliary fixing structures, inserted and embedded between the battery cell body 12 and the shell 1, and the position of the battery cell body 12 is limited, so that it maintains a relative position fixed with the shell 1. At the same time, the first insert 13 and the second insert 14 isolate the battery cell body 12 from the inner wall of the shell 1, so that when the shell 1 is subjected to an external collision, the first insert 13 and the second insert 14 evenly transmit the impact force to the battery cell body 12, so as to avoid the concave deformation of the shell 1 from squeezing and puncturing the surface of the battery cell body 12; When the first and second embedded parts 13 and 14 are used to limit the position of the battery cell body 12 , the number of the first and second embedded parts 13 and 14 to be installed is selected according to the size of the battery cell body 12 to meet the installation requirements of battery cell bodies 12 of different sizes.
