Lithium-ion batteries have become an important choice for ship power systems due to their high energy density, long cycle life and environmental protection characteristics.

[0003] Since the marine environment has high humidity, high salt spray and strong corrosion, it places extremely high demands on the sealing performance of the battery. Existing battery boxes mostly use external anti-corrosion coatings or simple sealing structures, but in long-term use, salt spray may still penetrate into the box through the gaps, corroding the battery cell tabs and connecting parts, causing battery performance degradation or even failure; traditional sealing designs often conflict with heat dissipation requirements. For example, the outer frame of the battery cell module itself tightly wraps the internal battery cell, and the battery shell is equipped with a sealing layer that wraps multiple battery cell modules layer by layer. This excessive sealing will hinder heat dissipation, and the open heat dissipation design is difficult to meet the anti-corrosion requirements. Summary of the invention

DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figures 1 to 5 The present invention provides a technical solution: an anti-corrosion battery cell module for marine vessels, the battery cell module 1 comprising a main outer frame 101 and a cylindrical battery cell 4, and also comprising a reference inner frame 2 and a plurality of movable inner frames 3, the reference inner frame 2 remains at the center position of the main outer frame 101 unchanged, the plurality of movable inner frames 3 are symmetrically distributed on both sides of the reference inner frame 2 and are limitedly slidably installed on the main outer frame 101, and a cylindrical battery cell 4 can be detachably installed in both the reference inner frame 2 and the plurality of movable inner frames 3; when the plurality of movable inner frames 3 are equidistantly changed in position on both sides of the reference inner frame 2, the spacing between two adjacent cylindrical battery cells 4 can be adjusted; Two groups of Z-axis stop frames 7 are symmetrically arranged on the main outer frame 101. The two groups of Z-axis stop frames 7 move toward each other in a straight line under the drive of the pushing component, so as to push the movable inner frame 3 to fit closely with the reference inner frame 2. Magnetic sheets 5 are fixedly arranged on the side walls of the Z-axis stop frames 7, the reference inner frame 2 and the movable inner frame 3. Repulsive force is generated between the two adjacent groups of magnetic sheets 5, so as to push the movable inner frame 3 to quickly unfold to both sides of the reference inner frame 2. When the Z-axis stop frames 7 fit with the reference inner frame 2 and the movable inner frame 3, the multiple cylindrical battery cells 4 are in a completely sealed state. When the Z-axis stop frames 7 are separated from the reference inner frame 2 and the movable inner frame 3, the multiple cylindrical battery cells 4 are in an independent heat dissipation state. A boss 6 is fixedly provided on one side of the Z-axis stop frame 7 close to the movable inner frame 3 . The boss 6 is engaged in the opening of the assembly groove. The boss 6 and the side wall of the Z-axis stop frame 7 form a step shape, which can better block the side wall of the battery module 1 .

[0036] Furthermore, through the design of the main outer frame 101, the reference inner frame 2, the multiple movable inner frames 3 and the Z-axis baffle frame 7, a modular structure of the battery module 1 outer frame is formed, and the multiple cylindrical battery cells 4 can be independently assembled. When the reference inner frame 2, the multiple movable inner frames 3 and the Z-axis baffle frame 7 are assembled with each other, they can have a sealing effect on the cylindrical battery cells 4; when the multiple movable inner frames 3 are successively away from the reference inner frame 2, the multiple cylindrical battery cells 4 are separated from each other, and each cylindrical battery cell 4 can obtain the effect of uniform ventilation and heat dissipation.

[0037] like Figure 3-Figure 5 As shown, both the movable inner frame 3 and the reference inner frame 2 are provided with assembly grooves for accommodating the cylindrical battery cells 4, and side grooves 301 are provided on the front and rear sides of the movable inner frame 3; the side grooves 301 and the assembly grooves are interconnected, and a blocking column 302 is provided in the side grooves 301, and a through hole 3021 is provided on the front and rear of the blocking column 302, and the blocking column 302 can adaptively perform positive and negative rotation movements according to the change of the position of the movable inner frame 3 through the cooperation of the driven component; the driven component includes a central axis 303, a moving gear 304 and a fixed rack 305; the upper end of the central axis 303 extends into the side groove 301 and is coaxially fixedly connected to the blocking column 302, and the lower end of the central axis 303 extends into the main outer frame 101 and is coaxially fixedly connected to the moving gear 304; a long slide groove cooperating with the moving gear 304 is provided on the upper surface of the bottom wall of the main outer frame 101, and the fixed rack 305 is fixedly arranged on the side wall of the long slide groove. When the movable inner frame 3 is in contact with the reference inner frame 2, the blocking column 302 rotates clockwise, and the through hole 3021 thereon is staggered with the side slot 301, and the side slot 301 is blocked at this time; when the movable inner frame 3 is away from the reference inner frame 2, the blocking column 302 rotates clockwise, and the through hole 3021 thereon is overlapped with the side slot 301, and the side slot 301 is opened at this time, so that the front and rear sides of the movable inner frame 3 can also be ventilated, further improving the heat dissipation effect of the cylindrical battery cell 4.

[0038] like Figure 4 as well as Figure 5 As shown, the blocking column 302 is rotatably mounted on the movable inner frame 3 through the central axis 303, the lower end of the blocking column 302 extends into the main outer frame 101 and is fixedly connected to a moving gear 304, a long slide groove for accommodating the moving gear 304 is provided on the upper surface of the bottom wall of the main outer frame 101, a fixed rack 305 meshing with the moving gear 304 is fixedly arranged in the long slide groove, and a through hole 3021 is opened through the front and rear of the blocking column 302; When the movable inner frame 3 is fitted with the reference inner frame 2, the blocking column 302 on the left side of the reference inner frame 2 rotates 90° clockwise, and the blocking column 302 on the right side of the reference inner frame 2 rotates 90° counterclockwise, and the through holes 3021 thereon are staggered with the assembly grooves, thereby blocking the side slots 301. Figure 1When the inner frame 3 is moved away from the reference inner frame 2, the blocking column 302 located on the left side of the reference inner frame 2 rotates 90° counterclockwise, and the blocking column 302 located on the right side of the reference inner frame 2 rotates 90° clockwise, and the through holes 3021 thereon coincide with the assembly grooves, thereby opening the side slots 301, referring to Figure 2 , which can further increase the ventilation volume of a single battery cell.

[0039] like Figure 2 as well as Figure 4 As shown, two groups of main push blocks 10 are installed in the upper limit sliding manner on the main outer frame 101, and the main push blocks 10 are pushed up and down by external force and act on the push assembly; the push assembly includes a cylindrical pin 8 and a vertical push bar 9, and the vertical push bar 9 is installed on the main outer frame 101 in a limited sliding manner. One end of the vertical push bar 9 extends into the Z-axis block frame 7 and is fixedly connected with the cylindrical pin 8, and the other end of the vertical push bar 9 is fixedly connected to the main push block 10, and an oblique groove 701 for accommodating the cylindrical pin 8 is opened through the side wall of the Z-axis block frame 7. By setting the cylindrical pin 8 and the vertical push bar 9 to be used in conjunction with the oblique groove 701, the up and down movement of the main push block 10 can be converted into the horizontal opposite movement of the two groups of Z-axis block frames 7, so that the battery module 1 can quickly switch between the two states of sealing and ventilation and heat dissipation.

[0040] Specifically, when the main push block 10 is pushed upward by an external force, the vertical push bar 9 also drives the cylindrical pin 8 thereon to move upward, and the cylindrical pin 8 acts on the oblique groove 701, and the cylindrical pin 8 moves from the left end (such as Figure 3 ) moves to the right end of the oblique groove 701 (as shown in Figure 2 As shown in the figure, because the cylindrical pin 8 only moves up and down, and its left and right positions remain unchanged, the position of the Z-axis baffle frame 7 will be moved from protruding from the main outer frame 101 to inside the main outer frame 101 due to the limiting extrusion of the cylindrical pin 8; that is, the Z-axis baffle frame 7 is subjected to force and pushes the movable inner frame 3 to move toward the direction of the reference inner frame 2. At this time, the reference inner frame 2, multiple movable inner frames 3 and the Z-axis baffle frame 7 fit each other. At the same time, driven by the moving gear 304, the fixed rack 305 and the central axis 303, the blocking column 302 blocks the side slot 301, so that the battery module 1 is in a completely closed state, which has a sealing protection effect on the cylindrical battery cell 4. Figure 1 ; When the external force cancels the squeezing force on the main push block 10, under the action of the repulsive force generated between the adjacent magnetic sheets 5, the Z-axis baffle frame 7 releases the pushing force on the movable inner frame 3, and the multiple movable inner frames 3 are also equidistantly translated and unfolded on both sides of the reference inner frame 2, and the oblique groove 701 of the Z-axis baffle frame 7 acts on the cylindrical pin 8, so that the vertical push bar 9 is forced to drive the main push block 10 to move downward. At the same time, under the action of the moving gear 304, the fixed rack 305 and the central axis 303 again, the blocking column 302 opens the side slot 301, and the battery module 1 can be ventilated and cooled in the four directions of front, back, left and right. Figure 3 .

[0041] like Figure 6-12 As shown, an anti-corrosion energy storage battery for marine vessels comprises a plurality of battery cell modules 1, an intermediate shell 11 and an outer shell 12; the frame of the battery cell module 1 itself provides a single-layer sealing protection for the cylindrical battery cell 4; a plurality of battery cell modules 1 are arranged inside the intermediate shell 11, and the number of the battery cell modules 1 is set to an odd number, and the main outer frame 101 of the battery cell module 1 located in the middle remains fixed; the battery cell modules 1 on both sides thereof can move as a whole; and the plurality of battery cell modules 1 perform equidistant translational motion under the drive of the main driving assembly, so as to realize ventilation and heat dissipation of the battery cell module 1 itself; the plurality of battery cell modules 1 are integrally wrapped by the intermediate shell 11, so as to realize double sealing protection for the cylindrical battery cell 4; the outer shell 12 is arranged outside the intermediate shell 11, and the outer shell 12 is in a long sealing state, so as to realize triple sealing protection for the cylindrical battery cell 4; Furthermore, the intermediate housing 11 is provided with Z-axis through grooves 13 and X-axis through grooves 14 on both sides of the Z axis and the X axis in sequence to realize ventilation and heat dissipation of the intermediate housing 11; an X-axis blocking plate 15 is clamped in the X-axis through groove 14, and the X-axis blocking plate 15 is fixedly arranged on the battery module 1 adjacent thereto, and the Z-axis blocking frame 7 on the battery module 1 can block the Z-axis through groove 13 when it is expanded outward; in this way, the intermediate housing 11 and the battery module 1 are in an alternating sealing state; The advantages of this energy storage battery are: the outer shell 12 is set to a long closed state to form a permanent barrier, ensuring that the core area of ​​the battery is always in a high protection state to prevent the invasion of salt spray, moisture and corrosive gases; and the second and first sealing structures work alternately. Under normal working conditions, the intermediate shell 11 is opened as the second sealing structure, and the first sealing structure is closed. A ventilation channel is formed between the intermediate shell 11 and the outer shell 12, which can dissipate heat for the battery module 1 as a whole; when the heat inside the battery module 1 increases sharply, the intermediate shell 11 is closed as the second sealing structure, and the first sealing structure is opened, and the unit frames in the battery module 1 are separated from each other, so that each single battery cell can be evenly ventilated and cooled.

[0043] Specifically, when the piston rod of the electric push cylinder 18 extends outward and pushes the plug-in plate cam 17, the connecting column 16 drives the battery module 1 to expand to both sides under the action of the wheel groove of the plug-in plate cam 17, and at this time, the X-axis blocking plate 15 also moves accordingly and blocks the X-axis through groove 14; when the piston rod of the electric push cylinder 18 retracts inward and pulls the plug-in plate cam 17, the connecting column 16 drives the battery module 1 to close inward under the action of the wheel groove of the plug-in plate cam 17, and at this time, the X-axis blocking plate 15 also moves accordingly and opens the X-axis through groove 14; like Figure 10-12 As shown, a linkage assembly is provided on the plug plate cam 17, which is used to squeeze the main push block 10 on the battery module 1 in the middle; the linkage assembly includes an active push plate 19, a first push block 20, an active tooth plate 21, a spur gear 22, a driven tooth plate 23 and a second push block 24, the active push plate 19 and the active tooth plate 21 are fixedly connected to the plug plate cam 17, and the first push block 20 and the second push block 24 both push a group of main push blocks 10 upward; one side of the bottom of the first push block 20 and the second push block 24 is set in an inclined shape, and the other side thereof is protrudingly provided with a limit block 25, and a return spring 26 is provided above the limit block 25; the two sides of the spur gear 22 are meshed and connected with the active tooth plate 21 and the driven tooth plate 23 in turn, so that the driven tooth plate 23 and the active push plate 19 perform opposite movements and push the second push block 24 and the first push block 20 in turn.

[0044] Furthermore, through the design of the active push plate 19, the first push block 20, the active tooth plate 21, the spur gear 22, the driven tooth plate 23 and the second push block 24, the linear motion of the plug-in plate cam 17 can be converted into an upward pushing force on the two sets of main push blocks 10 on the battery module 1 located in the middle, so that the battery module 1 in the middle can maintain its own position unchanged, and the movable inner frame 3 and the Z-axis stop frame 7 thereon can also be smoothly unfolded, so that the first-layer sealing structure on all battery modules 1 can be opened and closed normally.

[0045] like Figure 8 as well as Fig. 9As shown, the bottom wall of the intermediate shell 11 is provided with movable grooves 1101 of the same number as the main push blocks 10 at intervals, and the bottom of the main push blocks 10 are all arranged in an arc shape, and the main push blocks 10 move linearly with the battery cell module 1; when multiple battery cell modules 1 are unfolded to both sides, except for the main push block 10 on the middle battery cell module 1, all the remaining main push blocks 10 are released from the extrusion effect and are just stuck in the movable grooves 1101, and the battery cell modules 1 matched therewith are in a ventilation and heat dissipation state; when multiple battery cell modules 1 are closed toward the center, except for the main push block 10 on the middle battery cell module 1, all the remaining main push blocks 10 are moved away from the movable grooves 1101 and are squeezed upward by the bottom wall of the intermediate shell 11, and the battery cell modules 1 matched therewith are in a sealed state.
