In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0037] like Figures 1 to 10 As shown, in one embodiment, a battery cell support 1 includes at least two end caps 10. The end cap 10 has an inner groove 11 for receiving the battery cell. The outer side wall of the end cap 10 has at least one slot 12 and a half-groove 13. The outer side wall of the end cap 10 has at least one locking post 14. Any two slots 12 / half-grooves 13 / locking posts 14 are spaced apart. When any two end caps 10 are spliced ​​together, a locking post 14 of one end cap 10 is laterally locked into a slot 12 of the other end cap 10. The half-groove 13 of one end cap 10 and the half-groove 13 of the other end cap 10 are spliced ​​together to form a locking part. The locking part is used to pass through a locking rod 20. The locking rod 20 is used to longitudinally lock the two end caps 10.

[0038] It should be noted that the end cover 10 is a polygonal structure, for example, the end cover 10 is a hexagonal structure, further, three clamping grooves 12 and three clamping columns 14 are arranged on the outer side wall of the end cover 10, and the three clamping grooves 12 and the three clamping columns 14 are alternately arranged on the six outer sides of the end cover 10 respectively. The width of the inner bottom wall of the clamping groove 12 is greater than the width of the slot of the clamping groove 12, and the width of the clamping column 14 connected to one outer side of the end cover 10 is less than the width of the clamping column 14 away from one outer side of the end cover 10. In an embodiment, the three clamping grooves 12 are arranged on the adjacent three outer sides of the end cover 10, and the three clamping columns 14 are arranged on the other adjacent three outer sides of the end cover 10. Each clamping groove 12 and each clamping column 14 extend from one end face of the end cover 10 to the other end face in the axial direction. Further, one clamping column 14 on one end cover 10 is clamped with the clamping groove 12 on the other end cover 10, so that the radial direction of the two end covers 10 can be spliced. Further, the outer included angle between the two adjacent outer sides is an obtuse angle. Since the end cover 10 is a hexagonal structure, the two outer sides of the end cover 10 together form six obtuse angles of 120 degrees, so that the three end covers 10 can be spliced with each other. In order to facilitate description, the three end covers 10 are defined as a first end cover, a second end cover and a third end cover, the clamping column 14 on the first end cover is clamped with the clamping groove 12 on the second end cover, and the adjacent clamping column 14 and the clamping groove 12 on the third end cover are clamped with the clamping groove 12 on the first end cover and the clamping column 14 on the second end cover respectively, so that the plurality of end covers 10 can be spliced with each other to form a top frame 30 / bottom frame 40.

[0039] It should be noted that the end cover 10 is a hexagonal structure, and when a plurality of end covers 10 are spliced to form a top frame 30 / bottom frame 40, a honeycomb structure is formed, so that the firmness of the battery cell support 1 can be increased.

[0040] It should be noted that the end cover 10 is also provided with a plurality of half grooves 13, each half groove 13 extends from one end face of the end cover 10 to the other end face, and each half groove 13 is located at the angle position of the six outer sides, when two end covers 10 are spliced with each other, the two half grooves 13 together form a locking part which tends to be a circular groove structure, when three end covers 10 are spliced with each other, the locking part is in a hole type structure, in this way, the top frame 30 / bottom frame 40 spliced by one end cover 10 is formed with a plurality of hole type perforations, and each perforation is located at the angle position of the spliced end cover 10. Further, the two ends of the locking rod 20 are respectively arranged in the perforations of the top frame 30 / bottom frame 40, and the two ends of the locking rod 20 are respectively clamped with the perforations, so that the shaft center of each end cover 10 can be spliced. When any one of the battery cells fails, by rotating the locking rods 20 clamped with other end covers 10 on the end cover 10, the end cover 10 on the failed battery cell can be pulled out along the axial direction from the top frame 30 / bottom frame 40, and then the battery cell can be pulled out from the spliced top frame 30 / bottom frame 40 for replacement or repair. In this way, the maintenance personnel can quickly disassemble the single failed battery cell without disassembling the entire battery pack, thereby reducing unnecessary disassembly procedures and reducing the failure rate and labor cost of the battery pack after maintenance.

[0041] As Figures 1 to 8 In an embodiment, the end cover 10 is also provided with a through hole penetrating through both ends of the end cover 10, and a plurality of stop blocks 17 are arranged on the end cover 10, each stop block 17 is distributed along the circumferential direction of the through hole, and the through hole and each stop block 17 together form an inner groove 11.

[0042] It should be noted that the end cover 10 is provided with a through hole, and the through hole penetrates two end faces of the end cover 10 in the axial direction. The diameter of the inner groove 11 is greater than the diameter of the battery cell, so that the battery cell can be accommodated in the inner groove 11. Further, the end cover 10 is provided with a plurality of stop blocks 17, each stop block 17 is located on one end face of the end cover 10, each stop block 17 is L-shaped structure, one end of each stop block 17 is located on one side face of the end cover 10, the other end of each stop block 17 faces the axial direction of the through hole, and the one end of each stop block 17 facing the axial direction of the through hole extends into the through hole and forms the inner bottom wall of the inner groove 11. Further, when the battery cell is accommodated in the inner groove 11, the stop blocks 17 collectively abut against the end of the battery cell, so that the battery cell cannot extend out of one side face of the end cover 10. Further, when a plurality of end covers 10 are spliced together, and each stop block 17 on each end cover 10 is located on the same side face, so that when each battery cell is accommodated in each inner groove 11 one by one, the end of each battery cell abuts against a plurality of stop blocks 17 on one end cover 10 at the same time, for example, one end of a plurality of battery cells is accommodated in each inner groove 11 on the top frame 30 one by one, and the other end of the plurality of battery cells is accommodated in each inner groove 11 on the bottom frame 40 one by one, so that the top frame 30 and the bottom frame 40 collectively fix the plurality of battery cells. Further, the two ends of the locking rod 20 are respectively clamped with the through holes on the top frame 30 and the bottom frame 40, so that the top frame 30 and the bottom frame 40 collectively clamp the plurality of battery cells.

[0043] It should be noted that since each stop block 17 is L-shaped structure, the one end of each stop block 17 facing the axial direction of the through hole has a spacing with the end face of the end cover 10, when one end of the battery cell is accommodated in the inner groove 11, the end of the battery cell can extend out of the through hole and abut against each stop block 17, so as to connect the pole pieces of each battery cell. Further, each stop block 17 is provided with a rubber pad 171 on the side face facing the end face of the end cover 10, so that the stop block 17 and the end of the battery cell have a buffering effect, which avoids the top frame 30 / bottom frame 40 directly applying force to the battery cell when the top frame 30 / bottom frame 40 is extruded by external force, so as to avoid deformation or damage of the battery cell.

[0044] As shown in FIG. 1, Figures 2 to 8 In an embodiment, the end cover 10 is also provided with a plurality of heat dissipation grooves 15, each heat dissipation groove 15 is equally distributed along the inner side wall of the through hole.

[0045] It should be noted that each heat dissipation groove 15 is equally distributed along the inner side wall of the through hole, and the heat dissipation groove 15 extends along the axial direction of the through hole from one end of the end cover 10 to the other end, so that when the battery cell is accommodated in the inner groove 11, the two end faces of the end cover 10 can be communicated, and air can flow from one end face of the end cover 10 to the other end face, so that the heat generated by the battery cell can be quickly discharged to reduce the temperature in the entire battery pack.

[0046] As shown in Figures 3 to 8 , in an embodiment, the end cover 10 is provided with a plurality of clamping platforms 16, and one clamping platform 16 is located in one half slot 13, and each clamping platform 16 is clamped with a locking rod 20.

[0047] It should be noted that the clamping platform 16 is arranged on the inner side wall of the half slot 13, the clamping platform 16 is a half ring structure, the outer diameter of the clamping platform 16 is consistent with the diameter of the half slot 13, so that the clamping platform 16 can be fitted on the inner side wall of the half slot 13, and the arc length of the outer diameter of the clamping platform 16 is less than the arc length of the half slot 13, for example, the arc length of the outer diameter of the clamping platform 16 is half of the arc length of the half slot 13. Further, the inner diameter of the clamping platform 16 is consistent with the diameter of the locking rod 20, so that when the half slots 13 are jointly spliced into a through hole, the locking rod 20 can pass through the through hole.

[0048] As shown in Figures 1 to 3 , Figures 9 to 10 , in an embodiment, the locking rod 20 is provided with a plurality of bosses 21, each boss 21 is arranged at both ends of the locking rod 20, and each boss 21 is equidistantly distributed along the circumferential surface of the locking rod 20, and each boss 21 is one-to-one corresponding to each clamping platform 16.

[0049] It should be noted that the structure of the boss 21 is similar to that of the clamping platform 16, the boss 21 is arranged on the outer side wall of the locking rod 20, the boss 21 is also a half ring structure, the inner diameter of the boss 21 is consistent with the diameter of the locking rod 20, so that the boss 21 can be fitted on the outer side wall of the locking rod 20, and the outer diameter of the boss 21 is consistent with the diameter of the half slot 13, and the arc length of the outer diameter of the boss 21 is adapted to the spacing between the two clamping platforms 16, so that the boss 21 can pass through the spacing between the two clamping platforms 16. Further, three bosses 21 are arranged on both ends of the locking rod 20, each boss 21 is equidistantly distributed on the circumferential surface of the locking rod 20, and each boss 21 on both ends of the locking rod 20 is one-to-one corresponding, so that when the locking rod 20 drives the boss 21 on one end to pass through the through hole on the top frame 30, it can continue to pass through the through hole on the bottom frame 40.

[0050] As shown in Figures 3 to 8 , in an embodiment, the clamping platform 16 is provided with a limiting block 161, and the boss 21 is provided with a limiting groove 211, and the limiting block 161 is clamped with the limiting groove 211.

[0051] It should be noted that the locking platform 16 is provided with a limiting block 161, which is also inclined to a ring structure. The boss 21 is also inclined to a ring structure. When the locking rod 20 is inserted into the through hole on the top frame 30 / bottom frame 40, the limiting block 161 is located on the side of the locking platform 16 facing the boss 21, and the limiting groove 211 is located on the side of the boss 21 facing the locking platform 16. When the locking rod 20 is rotated so that the locking rod 20 drives the boss 21 and the locking platform 16 to align with each other along the axis of the through hole, the locking platform 16 pushes the boss 21 to prevent the locking rod 20 from being pulled out of the through hole. This prevents any one end cap 10 from being pulled out longitudinally from the top frame 30 / bottom frame 40. At the same time, the locking rod 20 drives the limiting groove 211 to engage with the limiting block 161, so that when the locking rod 20 rotates, it can accurately drive the boss 21 to align with the locking platform 16.

[0052] It should be noted that the slots of the inner grooves 11 on the top frame 30 and the bottom frame 40 are facing each other. When the two ends of the locking rod 20 are respectively engaged with the through holes on the top frame 30 and the bottom frame 40, the inner grooves 11 on the top frame 30 and the bottom frame 40 are used to clamp the battery cell together. Furthermore, when the two ends of the locking rod 20 are engaged with the top frame 30 and the bottom frame 40 respectively, the limiting block 161 on the top frame 30 and the limiting block 161 on the bottom frame 40 are both located on the same side of the half groove 13 relative to the half groove 13. For example, when the locking rod 20 rotates clockwise, the limiting block 161 on the top frame 30 is located on the side of the locking platform 16 away from the boss 21, so that the locking rod 20 can drive the boss 21 to engage with the locking platform 16. At the same time, relative to the base frame 40, when one end of the locking rod 20 on the top frame 30 rotates clockwise, the other end of the locking rod 20 on the base frame 40 rotates counterclockwise relative to the base frame 40. The limiting block 161 on the base frame 40 will be located on the side of the locking platform 16 closer to the boss 21, so that when the locking rod 20 rotates, the bosses 21 on both ends of the locking rod 20 can simultaneously engage with the locking platforms 16 on the top frame 30 / base frame 40.

[0053] like Figures 1 to 3 , Figures 9 to 10 As shown, in one embodiment, the locking rod 20 has twist grooves 22 on both ends.

[0054] It should be noted that when the locking rod 20 is inserted into the through hole, the two end faces of the locking rod 20 will face the surface of the top frame 30 / base frame 40. In this way, the two torsion grooves 22 are located on the end faces of the two ends of the locking rod 20 respectively. The operator can rotate the locking rod 20 by using a tool, such as a flathead screwdriver.

[0055] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
