[0022] like Figure 7 As shown, an embodiment of the present invention provides a carrier for a soft-pack battery 100, comprising a support mechanism 1 and a plurality of fixture mechanisms 2, wherein the fixture mechanisms 2 are provided with a receiving groove 211 for receiving the soft-pack battery 100; like Figure 3As shown, the support mechanism 1 includes a locking assembly 11, a first end plate 12, a second end plate 13, a first support rod 14, a second support rod 15, a first slide plate 16, a second slide plate 17, a guide rod 18, and a first elastic member 19 sleeved on the guide rod 18; the first support rod 14 and the second support rod 15 are installed between the first end plate 12 and the second end plate 13 at intervals, and the first slide plate 16 and the second slide plate 17 are both slidably installed on the first support rod 14 and the second support rod 15; a receiving space 1001 for clamping the soft-pack battery 100 is provided between the second slide plate 17 and the second end plate 13; the guide rod 18 is slidably connected between the first slide plate 16 and the second slide plate 17, and the opposite ends of the first elastic member 19 are respectively connected to the first slide plate 16 and the second slide plate 17. The second slide plate 17 abuts; the locking assembly 11 is installed on the first end plate 12 and connected to the first slide plate 16; it can be understood that the first end plate 12 and the second end plate 13 are respectively installed at the left and right ends of the first support rod 14 and the second support rod 15; the guide rod 18 can be installed on the first slide plate 16 and slidably connected to the second slide plate 17, and the guide rod 18 can also be installed on the second slide plate 17 and slidably connected to the first slide plate 16; the first elastic member 19 includes but is not limited to a spring, etc., and the first slide plate 16 can compress the first elastic member 19; the first end plate 12, the first slide plate 16, the second slide plate 17 and the third end plate are spaced apart along the first support rod 14, and the first support rod 14 and the second support rod 15 are arranged in parallel.

[0023] like Figure 1 and Figure 2 As shown, the locking assembly 11 is used to drive the first slide plate 16 to move, so that the second slide plate 17 clamps or releases the multiple carrier mechanisms located in the accommodating space 1001 .

[0024] Specifically, after the soft-pack battery 100 is installed in the receiving groove 211 of the fixture mechanism 2, multiple fixture mechanisms 2 are stacked in the receiving space 1001 between the second slide plate 17 and the second end plate 13; the locking assembly 11 drives the first slide plate 16 to move toward the direction close to the second slide plate 17, and the first slide plate 16 will compress the first elastic member 19, and the first elastic member 19 has a rebound force on the second slide plate 17 to move toward one end of the second end plate 13, so that the second slide plate 17 can clamp multiple fixture mechanisms 2 in the receiving space 1001, and adjacent The two jig mechanisms 2 can clamp the soft-pack battery 100 from opposite ends, ensuring the stability of the soft-pack battery 100 installed in the jig mechanism 2; when the locking assembly 11 releases the thrust on the first slide plate 16, both the first slide plate 16 and the second slide plate 17 can move toward the end away from the second end plate 13, so that the second slide plate 17 releases the multiple jig mechanisms 2 located in the accommodating space 1001. At this time, all the jig mechanisms 2 can be taken out from the accommodating space 1001, and the disassembly and assembly operation of the soft-pack battery 100 from the jig mechanism 2 is simple. In the present invention, the soft-pack battery 100 carrier can be moved to load multiple soft-pack batteries 100, so that multiple soft-pack batteries 100 can be installed in the container at one time through the soft-pack battery 100 carrier, which improves the manufacturing efficiency of the soft-pack battery 100; and the soft-pack battery 100 carrier has a simple structure, low manufacturing cost, and simple operation.

[0025] In one embodiment, if Figure 4 As shown, the locking assembly 11 includes an outer sleeve 111, an inner sleeve 112, a push rod 113, a second elastic member 114 and a limiting bead 115. The inner wall of the outer sleeve 111 is provided with a first limiting groove 1111, the push rod 113 is provided with a second limiting groove 1131, and the side wall of the inner sleeve 112 is provided with a receiving hole 1121; the outer sleeve 111 is slidably sleeved on the inner sleeve 112, the inner sleeve 112 is installed on the first end plate 12, the push rod 113 is slidably inserted in the inner sleeve 112 and connected to the first slide plate 16; the second elastic member 114 is sleeved on the inner sleeve The inner sleeve 112 is on the sleeve 112, and the opposite two ends are respectively connected to the inner sleeve 112 and the outer sleeve 111; the limiting bead 115 is installed in the accommodating hole 1121; it can be understood that the inner sleeve 112 is fixedly installed on the first end plate 12, and the second elastic member 114 includes but is not limited to a spring, etc., and the opposite two ends of the push rod 113 are both located outside the inner sleeve 112; the middle part of the limiting bead 115 is located in the accommodating hole 1121, the outer side of the limiting bead 115 can be located in the first limiting groove 1111, and the outer side of the limiting bead 115 can be located in the second limiting groove 1131.

[0026] like Figure 2 and Figure 5 As shown, the second elastic member 114 drives the outer sleeve 111 to move away from the first slide plate 16, and the limiting bead 115 is located in the accommodating hole 1121 and the second limiting groove 1131 to lock the push rod 113; specifically, when the outer sleeve 111 is in a free state, the second elastic member 114 pushes the outer sleeve 111 toward the end away from the first slide plate 16, and the push rod 113 moves toward the end away from the first slide plate 16, and the outer side of the limiting bead 115 slides The inner side of the limiting bead 115 is embedded in the second limiting groove 1131, and the middle part of the limiting bead 115 is located in the accommodating hole 1121, so that the inner sleeve 112 locks the push rod 113 by the limiting bead 115 embedded in the second limiting groove 1131, so that the first slide plate 16 does not move, the second elastic member 19 is kept in a compressed state, and then the second slide plate 17 presses the multiple fixture mechanisms 2 located in the accommodating space 1001.

[0027] like Figure 1 and Figure 6 As shown, the outer sleeve 111 moves in the direction close to the first slide plate 16, and the limiting bead 115 is located in the accommodating hole 1121 and the first limiting groove 1111 to unlock the push rod 113. It can be understood that an external gas source or the like can drive the outer sleeve 111 to move toward one end close to the first slide plate 16, and the first limiting groove 1111 of the outer sleeve 111 slides to the position of the limiting bead 115, so that the outer side of the limiting bead 115 can be embedded in the first limiting groove 1111, and the inner side of the limiting bead 115 can be separated from the second limiting groove 1131. At this time, the limiting bead 115 will release the locking state of the push rod 113, and the push rod 113 can release the thrust on the first slide plate 16, and the second slide plate 17 moves toward the end away from the second end plate 13, thereby releasing the fixture mechanism 2 located in the accommodating space 1001.

[0028] In this embodiment, the locking assembly 11 can automatically lock the push rod 113, so that the push rod 113 remains in a state of pressing the first slide plate 16 and the second elastic member 114 (that is, the support mechanism 1 remains in a state of clamping the fixture mechanism 2), thereby ensuring the stability of the support mechanism 1 in clamping multiple fixture mechanisms 2, and the locking assembly 11 is simple to operate to lock and unlock the push rod 113.

[0029] In one embodiment, if Figure 5As shown, along the extension line direction of the push rod 113 , the width of the second limiting groove 1131 is greater than the diameter of the limiting bead 115 ; it can be understood that when the second limiting groove 1131 is a semicircular groove, the inner diameter of the second limiting groove 1131 is greater than the diameter of the limiting bead 115 .

[0030] When the limiting bead 115 locks the push rod 113, the limiting bead 115 abuts against the inner wall of the second limiting groove 1131 toward the end close to the first slide 16; it can be understood that after the thrust of the outer sleeve 111 and the push rod 113 is cancelled, the inner side of the limiting bead 115 is embedded in the second limiting groove 1131, and the limiting bead 115 abuts against the inner wall of the second limiting groove 1131 toward the end close to the first slide 16, so that the limiting bead 115 will limit the push rod 113 from moving toward the end away from the first slide 16, and then the limiting bead 115 will lock the push rod 113.

[0031] When the push rod 113 moves to abut against the second slide plate 17, the limiting bead 115 moves in the second limiting groove 1131. Specifically, when the soft-pack battery 100 is in the formation stage, the jig mechanism 2 needs to provide a larger clamping force on the soft-pack battery 100. If only the first elastic member 19 is used to clamp the jig mechanism 2 through the second slide plate 17, the clamping force of the jig mechanism 2 on the soft-pack battery 100 is insufficient; when the soft-pack battery 100 is in the formation stage, the push rod 113 will further move toward one end of the second slide plate 17, and the limiting bead 115 moves in the second limiting groove 1131 until the push rod 113 is pressed against the second slide plate 17, and the push rod 113 has a sufficiently large pressing force on the jig mechanism 2 through the second slide plate 17. At this time, the jig mechanism 2 has a larger clamping force on the soft-pack battery 100. In this embodiment, the soft-pack battery 100 carrier has a relatively large clamping force on the soft-pack battery 100 , thereby satisfying the soft-pack battery 100 to complete the formation work under the relatively large clamping force.

[0032] In one embodiment, if Figure 3 As shown, a compression space is provided between the first slide plate 16 and the second slide plate 17, and a first through hole communicating with the compression space is provided on the first slide plate 16, and one end of the push rod 113 passes through the first through hole and extends into the compression space. It can be understood that the push rod 113 and the first through hole can be connected by a threaded structure; when the locking mechanism is in a locked state, the push rod 113 does not abut against the second slide plate 17, and the width of the compression space is large; when the locking mechanism is in a compressed state, the push rod 113 is compressed on the second slide plate 17, and the width of the compression space is small.

[0033] In one embodiment, if Figure 1 and Figure 7 As shown, the first hanging ear 212 adapted to the first support rod 14 and the second hanging ear 213 adapted to the second support rod 15 are respectively provided on opposite sides of the jig mechanism 2, the first hanging ear 212 can be detachably hung on the first support rod 14, and the second hanging ear 213 can be detachably hung on the second support rod 15. It can be understood that the first hanging ear 212 and the second hanging ear 213 are respectively located on the left and right sides of the jig mechanism 2, the first hanging ear 212 is hung on the first support rod 14, and the second hanging ear 213 is hung on the second support rod 15, thereby ensuring the stability of the jig mechanism 2 installed in the accommodating space 1001, and the jig mechanism 2 can be lifted by the support mechanism 1. In this embodiment, the design of the first hanging ear 212 and the second hanging ear 213 facilitates the disassembly and assembly between the jig mechanism 2 and the support mechanism 1.

[0034] In one embodiment, if Fig.13 As shown, the soft-pack battery carrier also includes a container 3, which includes a barrel cover 31 and a barrel 32 provided with a storage space for accommodating the support mechanism 1; the barrel cover 31 is detachably mounted on the barrel 32 and is used to cover the storage space 321. It can be understood that the soft-pack battery 100 is installed on the fixture mechanism 2, and after multiple fixture mechanisms 2 are stacked and installed on the support mechanism 1, the support mechanism 1 is placed in the storage space 321 of the barrel 32, and finally the barrel cover 31 is covered. In this embodiment, the design of the container 3 allows the soft-pack battery 100 to be pressurized, depressurized, heated, and other processes in a closed space, thereby completing processes such as isobaric negative pressure, isobaric high pressure static, and isobaric negative pressure static of the soft-pack battery 100 at high temperature.

[0035] In one embodiment, if Figures 7 to 10 As shown, the fixture mechanism 2 includes a switching valve 22 and a fixture seat 21 provided with the receiving groove 211, and the fixture seat 21 is provided with a liquid storage chamber 214 and a liquid outlet 215 connected to the liquid storage chamber 214, and the liquid outlet 215 is used to connect to the injection hole 101 of the soft-pack battery 100; it can be understood that the liquid outlet 215 is arranged on the bottom wall of the receiving groove 211.

[0036] The switching valve 22 includes a valve seat 221 and a valve core 222 provided with a valve hole 2221, the valve seat 221 is provided with a sliding hole 2211 and a second through hole 2212 and a third through hole 2213 both connected to the sliding hole 2211; the valve core 222 is slidably installed in the sliding hole 2211, and is used to control the connection and disconnection between the second through hole 2212 and the third through hole 2213; preferably, the second through hole 2212 and the third through hole 2213 are coaxially arranged, and the axis of the second through hole 2212 is perpendicular to the axis of the sliding hole 2211.

[0037] The valve seat 221 is mounted on the fixture seat 21 , and one end of the third through hole 2213 away from the sliding hole 2211 is connected to the liquid storage chamber 214 . It can be understood that the third through hole 2213 is located directly above the liquid storage chamber 214 .

[0038] Specifically, the soft-pack battery 100 is installed in the receiving groove 211 of the fixture seat 21, and the injection hole 101 of the soft-pack battery 100 is connected to the liquid outlet hole 215, so that the electrolyte in the liquid storage cavity 214 can flow into the inner cavity of the soft-pack battery 100 through the liquid outlet hole 215, thereby completing the injection work of the soft-pack battery 100.

[0039] In this embodiment, when the valve core 222 slides to the blocking position in the sliding hole 2211, the valve core 222 can play a role in blocking the channel between the second through hole 2212 and the third through hole 2213. At this time, the liquid storage chamber 214 is not connected to the second through hole 2212; when the valve core 222 slides to the conducting position in the sliding hole 2211, the second through hole 2212 is connected to the third through hole 2213 through the valve hole 2221, and the injection needle of the external injection device can sequentially pass through the second through hole 2212, the valve hole 2221 and the third through hole 2213 to extend into the liquid storage chamber 214, so that the external injection device can directly inject electrolyte into the liquid storage chamber 214, and the valve core 222 will not be contaminated with electrolyte, which ensures the cleanliness of the switching valve 22 while improving the injection accuracy of the fixture mechanism 2.

[0040] In addition, when the liquid outlet hole 215 is located directly below the second through hole 2212, the external sealing member can sequentially pass through the second through hole 2212, the valve hole 2221, the third through hole 2213 and the liquid storage chamber 214 to seal the liquid outlet hole 215, thereby facilitating cleaning of the liquid storage chamber 214 and other operations.

[0042] When the switching valve 22 is in a conducting state, the second through hole 2212 is connected to the third through hole 2213 through the valve hole 2221; specifically, when the valve core 222 moves in the sliding hole 2211 until the valve hole 2221 is directly below the second through hole 2212, the second through hole 2212 is connected to the third through hole 2213 through the valve hole 2221.

[0043] When the switching valve 22 is in the blocking state, the blocking portion 2222 blocks the passage between the second through hole 2212 and the third through hole 2213. Specifically, when the valve core 222 slides in the sliding hole 2211 until the blocking portion 2222 is located directly below the second through hole 2212, the blocking portion 2222 blocks the second through hole 2212, that is, the second through hole 2212 is not connected to the third through hole 2213.

[0045] In one embodiment, the battery mechanism further includes a heating element (not shown in the figure) mounted on the fixture seat 21, and the heating element is used to heat the soft-pack battery 100 located in the receiving groove 211.

It can be understood that the second seat body 217 can be detachably mounted on the first seat body 216 through a snap structure, a magnetic structure, etc.; the liquid injection hole 101 of the battery is arranged on the side pocket 104. To further illustrate, the second seat body 217 is made of a non-conductive material, and the first seat body 216 can be made of a conductive material with relatively high strength, thereby extending the service life of the jig mechanism 2 while ensuring the safety of the jig mechanism 2 .

[0047] In this embodiment, the second seat body 217 can be detachably mounted on the first seat body 216, and different second seat bodies 217 (the sizes of the second groove 2112 on the second seat body 217 are different) can be replaced, so that the jig mechanism 2 can install soft-pack batteries 100 of different sizes, thereby improving the applicability and versatility of the jig mechanism 2.

[0048] In one embodiment, if Figure 7 and Fig. 9As shown, the fixture seat 21 also includes a third seat body 218 detachably mounted on the end of the first seat body 216 away from the second seat body 217, and the third seat body 218 is provided with a third groove (not shown in the figure) for accommodating the battery body 105. It can be understood that the third seat body 218 can be detachably mounted on the first seat body 216 by a snap structure, a magnetic structure, etc. Specifically, after the soft-pack battery 100 is installed in the accommodating groove 211, the two fixture mechanisms 2 are stacked together, and the second seat body 217 and the third seat body 218 press the soft-pack battery 100 from the left and right sides respectively, that is, the left side of the soft-pack battery 100 is located in the second groove 2112, and the right side of the soft-pack battery 100 is located in the third groove. In this embodiment, the fixture mechanism 2 can accommodate soft-pack batteries 100 protruding on both the left and right sides, further improving the applicability and versatility of the fixture mechanism 2.

[0049] It should be noted that when the soft-pack battery 100 protrudes toward only one side, the side of the third base 218 that is away from the first base 216 is a flat surface.

[0050] In one embodiment, if Figure 7 and Fig. 9 As shown, the fixture mechanism 2 also includes a positive electrode conductive member 2171 and a negative electrode conductive member 2172 both mounted on the second seat 217, the positive electrode conductive member 2171 is used to electrically connect the positive electrode ear 102 of the soft-pack battery 100, and the negative electrode conductive member 2172 is used to electrically connect the negative electrode ear 103 of the soft-pack battery 100. It can be understood that after the positive electrode conductive member 2171 and the negative electrode conductive member 2172 are connected to the external power supply, the soft-pack battery 100 can be charged and discharged, thereby completing the formation process of the soft-pack battery 100.

[0051] In one embodiment, if Figure 7 As shown, the two opposite sides of the jig mechanism 2 are respectively provided with positioning pins 2161 and positioning holes; when two adjacent jig seats 21 are assembled, the positioning pin 2161 on one jig seat 21 is inserted into the positioning hole of the other jig seat 21. It can be understood that the positioning pins 2161 and the positioning holes are respectively arranged on the two opposite sides of the first seat body 216, and the positioning pins 2161 inserted into the positioning holes ensure the assembly accuracy of the two adjacent jig seats 21.

[0053] The annular groove is used to accommodate the elastic liquid injection nozzle 106, and the convex column 219 is inserted into the liquid injection hole 101. Specifically, a plurality of jig mechanisms 2 with soft-pack batteries 100 installed are stacked in the accommodating space 1001, and the second slide plate 17 and the second end plate 13 clamp the plurality of jig mechanisms 2 located in the accommodating space 1001, and when the locking mechanism is in a locked state, two adjacent jig mechanisms 2 have a clamping force, ensuring that while the two adjacent jig mechanisms 2 clamp the soft-pack batteries 100, the convex column 219 is inserted into the elastic liquid injection nozzle 106, and ensuring the sealing of the convex column 219 inserted into the elastic liquid injection nozzle 106, avoiding the accident of leakage of the jig mechanism 2 and the soft-pack battery 100.

[0054] In one embodiment, the fixture mechanism 2 further includes a fourth sealing ring installed in the annular groove and arranged around the boss 219. It can be understood that when the boss 219 is inserted into the injection hole 101 of the flexible injection nozzle, the sealing ring abuts against the outer wall of the flexible battery, so that the design of the fourth sealing ring further ensures the sealing of the boss 219 and the elastic injection nozzle 106.
