It has strong flexibility and compatibility. Moreover, it solves the problem of additionally matching the lower pressing modules 1 of different specifications due to the differences in the overall design of the battery modules, which not only simplifies the production process of the battery pack, but also the design output of the lower pressing module 1 effectively reduces the cost of the battery pack.

Preferably, two first linear telescopic members are provided, both of which are pneumatic telescopic cylinders. The telescopic rod of the first linear telescopic member is positioned downward relative to the fixed cylinder of the first linear telescopic member. The telescopic rod of the first linear telescopic member is fixedly connected to the mounting assembly 12, so that the first linear telescopic member drives the mounting assembly 12 and the pressing fixture 13 to move upward and downward in the height direction.

[0083] Please see the attached Figures 10-14 In some embodiments of the present application, the mounting assembly 12 includes a mounting plate 121 and hook portions 122 formed on opposite sides of the mounting plate 121. The opposite sides of the pressing fixture 13 are passed through the hook portions 122.

[0086] Please refer to the accompanying drawings Figure 10 In some embodiments, the hooking part 122 is L-shaped, and the L-shaped hooking part 122 includes a vertical segment 1221 and a horizontal segment 1222 arranged vertically; the vertical segment 1221 is connected to the bottom end surface of the mounting plate 121 vertically; and the horizontal segment 1222 is connected to the end of the vertical segment 1221 away from the mounting plate 121 and is parallel to the mounting plate 121.

[0087] In some embodiments, the first side and the second side are parallel to the first direction. The length of the hooking part 122 on the first side can be much smaller than the length of the first side, and in this case, the first side is provided with a plurality of hooking parts 122 arranged at intervals along the length direction of the first side; or the length of the hooking part 122 on the first side is equal to or substantially equal to the length of the first side, and in this case, the first side is provided with only one hooking part 122. Similarly, the length of the hooking part 122 on the second side can be much smaller than the length of the second side, and in this case, the second side is provided with a plurality of hooking parts 122 arranged at intervals along the length direction of the second side; or the length of the hooking part 122 on the second side is equal to or substantially equal to the length of the second side, and in this case, the second side is provided with only one hooking part 122.

[0088] In some embodiments, a first hooking part mounting hole is formed through the mounting plate 121, and a second hooking part mounting hole is formed through the hooking part 122, and a hooking part fastener is sequentially inserted through the first hooking part mounting hole and the second hooking part mounting hole to detachably connect the hooking part 122 to the mounting plate 121.

[0089] In some embodiments, the hooking part 122 can be bonded to the mounting plate 121; or the hooking part 122 can be welded to the mounting plate 121.

The first positioning member 123 is arranged at a position close to the third side of the mounting plate 121; the pressing jig 13 is pushed from the third side of the mounting plate 121 to extend out of the fourth side of the mounting plate 121, so that the pressing jig 13 is arranged in the hooking part 122.

[0093] During the pushing of the pressing jig 13 to be arranged in the hooking part 122, the first positioning member 123 on the mounting plate 121 is first lifted upward to avoid blocking the pushing movement of the pressing jig 13; then the force for lifting the first positioning member 123 upward is removed, and the pressing jig 13 is continuously pushed until the second positioning hole of the pressing jig 13 and the first positioning member 123 are opposite in position in the height direction, and the first positioning member 123 automatically falls into the second positioning hole; at this time, the pressing jig 13 cannot continue to move, realizing the rough positioning of the assembly of the mounting plate 121 and the pressing jig 13, and making the assembly of the pressing jig 13 more accurate and reliable.

[0094] Please refer to the accompanying drawings Figures 11-12 , 14, in some embodiments, a third positioning hole is formed on the mounting plate 121, and the pressing jig 13 is formed with a fourth positioning hole opposite to the third positioning hole in position, and the second positioning member 124 is sequentially inserted into the third positioning hole and the fourth positioning hole to realize the positioning of the mounting plate 121 and the pressing jig 13.

[0095] Wherein it needs to be explained that the second positioning member 124 is a bolt structure which can be separated from the third positioning hole and the fourth positioning hole.

[0096] When the rough positioning of the assembly of the mounting plate 121 and the pressing jig 13 is completed, the third positioning hole and the fourth positioning hole are opposite in position in the height direction; at this time, the second positioning member 124 is sequentially inserted into the third positioning hole and the fourth positioning hole to complete the fine positioning of the assembly of the mounting plate 121 and the pressing jig 13. As above, the assembly of the pressing jig 13 is further made more accurate and reliable.

[0099] When the assembly positioning of the pressing jig 13 on the mounting assembly 12 is completed, the locking member 125 is inserted into the locking hole, and the locking member 125 is screwed until the locking member 125 abuts against the pressing jig 13. As described above, the play gap between the pressing jig 13 and the mounting plate 121 is eliminated, and the fixing of the pressing jig 13 on the mounting assembly 12 is more reliable, and the positional shift movement does not occur.

[0100] Please refer to the accompanying drawings Figures 10-13 In some embodiments of the present application, the bottom of the pressing jig 13 is provided with a plurality of pole abutting members 131. The pole abutting member 131 can move in the height direction and elastically abut against the pole 51.

[0102] All the pole abutting members 131 are opposite to all the poles 51 of the plurality of battery monomers 5 arranged side by side; when the heights of the plurality of battery monomers 5 are inconsistent, the play gap between the pole abutting member 131 and the pole 51 is eliminated through the telescopic movement of the pole abutting member 131 in the height direction, so that the positional shift movement of the battery monomer 5 in the height direction during the peristalsis pressure process is prevented, and the pole 51 is well protected.

[0103] Please refer to 10, 12-14, in some embodiments, the pressing jig 13 includes a support plate 132, a connecting plate 133, a mounting block 134, and an elastic member 135.

The pressing fixed end module 3 comprises a second pressing plate 31, which can change position between a second working position and a second avoiding position. The second working position is arranged opposite and parallel to the contact surface along the first direction.

When the pressing module 2 presses the contact surface, the second pressing plate 31 is fixed at the second working position, and the contact surface abuts against the second pressing plate 31.

[0130] Before the multiple battery monomers 5 arranged in parallel are subjected to peristaltic pressing, the battery monomers 5 need to be placed in position, at which time the second pressing plate 31 is moved to the second avoiding position, and the second pressing plate 31 no longer blocks the placement of the battery monomers 5. After the battery monomers 5 are placed in position, the second pressing plate 31 is moved to the second working position so that the abutting surface abuts against the second pressing plate 31. Finally, the multiple battery monomers 5 are subjected to peristaltic pressing by the pressing module 2.

[0131] Please refer to the accompanying drawings Figures 19-21 In some embodiments of the present application, the pressing fixed-end module 3 comprises a transmission assembly 32.

The first transmission member 321 is movable in the height direction; the second transmission member 322 is fixedly connected to the second pressing plate 31 and in transmission abutment with the first transmission member 321. The second transmission member 322 is moved in the first direction under the transmission of the first transmission member 321, so that the second pressing plate 31 is moved from the second avoiding position to the second working position.

[0132] Please refer to the accompanying drawings Figure 19 , 21 -22, it should be noted that the pressing fixed-end module 3 comprises a fourth driving assembly 34, which drives the first transmission member 321 to move up and down in the height direction. The fourth driving assembly 34 comprises a fourth linear extension and retraction member, which can be selected from any one of a telescopic electric cylinder, a telescopic pneumatic cylinder, and a telescopic hydraulic cylinder; the fourth linear extension and retraction member drives the first transmission member 321 to move up and down in the height direction.

[0133] As described above, the movement of the first transmission member 321 in the height direction can be converted into the movement of the second transmission member 322 in the first direction, realizing the conversion of the transmission direction, and the transmission assembly 32 does not occupy a large space volume of the pressing device, making the structure more compact and the integration higher.

[0134] Please refer to the accompanying drawings Figure 20 In some embodiments, the first transmission member 321 comprises a transmission roller 3211 fixedly connected to the extension rod of the fourth linear extension and retraction member through a roller fixing block. The second transmission member 322 comprises a transmission surface 3221; from bottom to top, the transmission surface 3221 comprises a first vertical section, an inclined section, and a second vertical section connected in sequence; from bottom to top, the inclined section is inclined away from the placement platform 23. The transmission surface 3221 is located on the side surface of the second transmission member 322 away from the placement platform 23; the first transmission member 321 is located on the side of the second transmission member 322 away from the placement platform.

[0135] When the fourth driving assembly 34 drives the first transmission member 321 to move upward along the height direction, the transmission roller 3211 moves upward and is in transmission cooperation with the transmission surface 3221; when the transmission roller 3211 moves to the inclined section of the transmission surface 3221, the first transmission member 321 drives the second transmission member 322 to move along the first direction and towards the placing platform 23; until the transmission roller 3211 moves to the second vertical section, the second transmission member 322 stops moving, and the second pressing plate 31 moves to the second working position.

[0136] When the transmission roller 3211 moves upward along the height direction, the transmission roller 3211 is in rolling contact with the transmission surface 3221, which reduces the friction loss between the two and is conducive to prolonging the service life of the transmission assembly 32.

When the second transmission member 322 is located at the second avoiding position, the reset member 33 is in a natural state or a compressed deformation state; as described above, when the fourth driving assembly 34 drives the first transmission member 321 to move upward, the second transmission member 322 is always in abutment with the first transmission member 321 under the action of the force of the reset member 33 returning to its original shape, and the two are in transmission cooperation.

[0139] When the fourth driving assembly 34 drives the first transmission member 321 to move upward along the height direction, the transmission roller 3211 moves upward and is in transmission cooperation with the transmission surface 3221, so as to drive the second transmission member 322 along with the second pressing plate 31 to move along the first direction and towards the placing platform 23, until the second pressing plate 31 moves to the second working position, at which time the reset member 33 is compressed and deformed under the abutment of the first transmission member 321. When the fourth driving assembly 34 drives the first transmission member 321 to move downward along the height direction, the transmission roller 3211 moves downward and is out of transmission cooperation with the transmission surface 3221, at which time the force of abutting and compressing the reset member 33 disappears, the reset member 33 returns to its original shape, so as to drive the second transmission member 322 along with the second pressing plate 31 to move along the first direction and away from the placing platform 23, until the second pressing plate 31 automatically returns to the second avoiding position.

[0140] As described above, the reset member 33 is simple in structure and can automatically reset the second pressing plate 31 from the second working position to the second avoiding position, thereby saving the manufacturing cost.
