DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present application, a battery cell fixture provided by the invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figure 1 and Figure 2 , Figure 1 This is a front view of the first embodiment of the battery fixture of the present application; Figure 2 yes Figure 1 A schematic diagram of the structure shown.

[0032] The battery cell fixture of this embodiment includes a bottom plate 11 and a plurality of partition plates 2, wherein the plurality of partition plates 2 are arranged on the bottom plate 11 at intervals along a preset direction, wherein the preset direction is Figure 1 The direction indicated by the double-headed arrow. The number of partitions 2 is not limited, as long as it can meet the load of the battery cell. Since the spacing between the partitions 2 is adjustable, when the partitions 2 are close to each other, the battery cell inserted between the partitions 2 can be clamped from opposite sides. Among them, the battery cell can be a plate-shaped battery cell, a soft-pack battery cell, etc.

[0033] In order to reduce the wear of the bottom of the battery cell during the process of clamping or opening the clamping jig, the battery cell jig in this embodiment includes a flexible drag film 3, which has a flexible property, and the wear of the bottom of the battery cell is reduced by the flexible drag film 3. Specifically, the flexible drag film 3 is at least partially arranged between the partitions 2, and the flexible drag film 3 is at least partially arranged in a concave direction along the insertion direction of the battery cell relative to the partition 2, and the concave arrangement is used to support the battery cell inserted between the partitions 2. The flexible drag film 3 between the partitions is used as the bottom support of the battery cell. When the battery cell jig is clamped or opened, the flexible drag film 3 can expand and contract under the extrusion or tension force between the partition 2 and the adjacent partition 2. Compared with the existing battery cell jig, it can avoid the friction between the bottom of the battery cell and the bottom of the battery cell jig to form wear.

[0034] See also Figure 3 , Figure 4 and Figure 5 , Figure 3 This is a front view of the first embodiment of the flexible drag film of the present application; Figure 4 This is a front view of the second embodiment of the flexible drag film of the present application; Figure 5 It is a side view of the third embodiment of the flexible drag membrane of the present application.

[0035] In order to improve the stability of the flexible drag film 3 installed on the adjacent partition 2, the flexible drag film 3 in this embodiment includes a load-bearing section 31 and two installation sections 32, the two installation sections 32 are respectively connected to the two ends of the load-bearing section 31, the load-bearing section 31 is concavely arranged, the concavely arranged load-bearing section 31 is used to carry the battery cell, and the two installation sections 32 are respectively arranged on the partitions 2 on both sides of the load-bearing section 31 to achieve the installation of the flexible drag film 3. Preferably, the load-bearing section 31 and the two installation sections 32 are integrally formed.

[0036] Specifically, in order to facilitate the installation of the flexible drag membrane 3 on the partition 2, the installation section 32 is arranged parallel to the top of the partition 2, and at least one screw hole is opened on the installation section 32, so that the installation section 32 can be installed on the partition 2 by screws.

[0037] Specifically, the load-bearing section 31 is arranged in a V shape, which facilitates the insertion of the battery cell into the load-bearing section 31. Among them, the flexible drag film 3 is arranged continuously or in sections along a preset direction, such as in a V shape, a W shape, or a shape composed of several V shapes. The specific shape of the flexible drag film 3 is not limited, as long as the load-bearing section 31 is in a V shape and the battery cell load can be satisfied. Of course, in order to improve the installation efficiency of the battery cell fixture, the flexible drag film 3 can be set into a shape composed of several continuous V shapes, and the flexible drag film 3 can be directly covered on several partitions 2 and then fixed.

[0038] In actual process, in order to reduce the wear of the bearing section 31 on the bottom of the battery cell, the bottom of the bearing section 31 is arranged in an arc shape.

[0039] See also Figure 6 , Figure 6 It is a side view of an embodiment of a partition of the present application.

[0040] Combination Figure 1 and Figure 2 In this embodiment, the battery fixture includes a first side plate 12 and a second side plate 13, which are arranged opposite to each other and fixed to the bottom plate 11 at intervals along a preset direction. A plurality of partitions 2 are arranged between the first side plate 12 and the second side plate 13.

[0041] In order to clamp or open the multiple partitions 2 along a preset direction, the battery cell fixture in this embodiment also includes at least one sliding rod 14, and the at least one sliding rod 14 is connected between the first side plate 12 and the second side plate 13. The multiple partitions 2 are slidably arranged on the at least one sliding rod 14, and the sliding rod 14 plays a guiding role, so that the multiple partitions 2 can slide along the sliding rod 14.

[0042] For example, when there is one slide bar, in order to maintain the stability of the multiple partitions, the slide bar slides at the center of the multiple partitions. When there are two slide bars, the slide bars are respectively arranged at both ends of the partition, and the specific positions are not limited. Of course, there can also be three or four slide bars.

[0043] In order to ensure the stability of the movement of the multiple partitions 2, in this embodiment, there are four sliding rods 14, which are respectively provided at the upper and lower ends of both sides of the partitions 2.

[0044] In one embodiment, the battery fixture further includes a plurality of coupling assemblies, and the plurality of coupling assemblies are respectively connected between each pair of adjacent separators 2 to limit the maximum spacing distance between each pair of adjacent separators 2. The maximum spacing distance between adjacent separators 2 is as follows: Figure 1 There are multiple coupling assemblies, and the specific number is not limited.

[0045] Specifically, a coupling hole 21 is provided on the partition 2, and the coupling hole 21 is used to respectively accommodate the coupling assembly connected to the partition 2 where the coupling hole 21 is located and the adjacent partition 2, so that the coupling assembly can be slidably set in the coupling hole 21 in the adjacent partition 2, thereby limiting the maximum spacing distance between the adjacent partitions 2.

[0046] In order to prevent the coupling assemblies between each pair of adjacent partitions 2 from interfering with each other, at least two coupling holes 21 are provided at both ends of the partition 2 so that the coupling assemblies are staggered with adjacent coupling assemblies in a preset direction.

[0047] Specifically, the partition 2 is provided with an avoidance hole 22, and the avoidance hole 22 is used to avoid the coupling assembly connected between other partitions 2 other than the partition 2 where the coupling hole 21 is located. The number of the avoidance hole 22 is one or more.

[0048] Specifically, the partition 2 is provided with a slide rod hole 23, and the number of the slide rod holes 23 is one or more, and is not specifically limited. For example, when a slide rod hole is provided on the partition, the number of the slide rod is one, and the slide rod passes through the slide rod holes on the partitions in sequence. When two slide rod holes 23 are provided at both ends of the partition 2, the number of the slide rods 14 is four.

[0049] In order to prevent sliding wear between the slide bar 14 and the partition 2 and improve the smoothness of the sliding of the partition 2, in this embodiment, a guide sleeve 8 is fixedly arranged on each corresponding slide bar hole 23, and the guide sleeve 8 is sleeved on the slide bar 14 to improve the smoothness of the sliding of the partition 2. In order to simplify the installation of the guide sleeve 8, the slide bar hole 23 is set to be open, so that the guide sleeve 8 is conveniently fixed on the slide bar hole 23.

[0050] At the same time, in order to simplify the structure of the battery fixture, reduce the installation cost of the battery fixture, and facilitate the adjustment of the maximum spacing between the two groups of partitions 2 according to actual needs, the coupling hole 21 is set as an opening in this embodiment. Specifically, the coupling assembly includes a coupling rod 4 and a stop block (not shown in the figure), and the coupling rod 4 can be placed in the coupling hole 21 through the opening to facilitate the installation of the coupling rod 4 in the coupling hole 21. Of course, in order to prevent the coupling rod 4 from falling from the open coupling hole 21 during the installation of the coupling rod 4 in the coupling hole 21, the bottom of the coupling hole 21 is set toward the bottom plate 11.

[0051] The stop blocks are respectively arranged at both ends of the coupling rod 4 , and the radial dimension of the stop blocks is larger than the radial dimension of the coupling hole 21 , so that the coupling rod 4 will not separate from the partition plate 2 when it automatically moves in a preset direction.

[0052] In other embodiments, a baffle (not shown in the figure) is provided on the partition 2 , and the baffle is located at the open coupling hole 21 , which can prevent the coupling rod 4 from detaching from the partition 2 from the open end of the coupling hole 21 .

[0053] See also Figure 7 , Figure 7 It is a partial schematic diagram of the second embodiment of the battery cell fixture of the present application.

[0054] In this embodiment, the battery cell jig includes a partition driving member (not shown in the figure), which is arranged on the first side plate 12, and is used to drive the partitions 2 adjacent to the first side plate 12 to move toward the second side plate 13, thereby pushing the multiple partitions 2 to move closer to each other, so as to achieve the clamping of the battery cell jig. The partition driving member is further used to drive the partitions 2 adjacent to the first side plate 12 to move toward the first side plate 12, thereby pulling the multiple partitions 2 away from each other through the shaft coupling assembly, so as to achieve the opening of the battery cell jig.

[0055] In an alternative embodiment, the partition driving member is disposed on the second side plate, and the partition driving member is used to drive the partitions adjacent to the second side plate to move toward the first side plate, thereby pushing the multiple partitions to move closer to each other, so as to achieve the clamping of the battery cell jig. The partition driving member is further used to drive the partitions adjacent to the second side plate to move toward the second side plate, thereby pulling the multiple partitions away from each other through the coupling assembly, so as to achieve the opening of the battery cell jig.

[0056] Specifically, a reserved hole 121 is provided on the first side plate 12 or the second side plate 13 to provide an installation position for the partition plate driving member. Of course, the partition plate driving member can also be installed at other positions, which is not specifically limited.

[0057] See also Figure 8 , Fig. 9 and Fig.10 , Figure 8 is a side view of the first embodiment of the stopper assembly of the present application; Fig. 9 is a side view of a second embodiment of the stopper assembly of the present application; Fig.10 It is a top view of the third embodiment of the stop assembly of the present application.

[0058] Combination Figure 1 In this embodiment, the battery cell fixture also includes a stopper assembly 5, and the stopper assembly 5 is used to limit the battery cell fixture in an open state and a clamped state. Specifically, the stopper assembly 5 includes a base 51, a seesaw 52, ​​and a seesaw driving member (not shown in the figure). The base 51 is arranged on the bottom plate 11 and is located below the partition 2, and its specific installation position is not limited. The seesaw 52 includes a first end and a second end relative to each other, and the middle part of the seesaw 52 rotates on the base 51, wherein the first end of the seesaw 52 is located above the base 51, and the second end of the seesaw 52 extends out of the base 51. Since the stopper assembly 5 is located on the bottom plate 11 and at the lower end of the partition 2, the stopper assembly 5 drives the seesaw 52 to rotate, so that when multiple partitions 2 are close to each other and / or away from each other, the seesaw 52 can be used to lock the partition 2 thereon. As shown Figure 8 The stop assembly 5 is in a tilted state, used to lock the partition 2; Fig. 9 The stop assembly 5 is in a non-tilted state.

[0059] When the second end of the seesaw 52 is subjected to a downward force from the seesaw driving member, the first end of the seesaw 52 moves upward to block the movement of the partition 2, thereby preventing the partition 2 from moving forward and achieving a locking effect. Fig. 9 In the direction indicated by the arrow, the first end of the rocker 52 moves downward to a point where it is not blocked by the moving path of the partition 2, thereby achieving the unlocking effect.

[0060] In order to improve the stability of the stopper assembly 5 in blocking the movement of the partition 2, the stopper assembly 5 also includes an elastic member 53, which is elastically supported between the base 51 and the first end of the seesaw 52. When the battery fixture is in the open state, the seesaw 52 is always on a horizontal plane parallel to the bottom plate 11 under the driving force of the seesaw driver, and the elastic member 53 is in a compressed state. When the battery fixture is in the clamped state, the seesaw driver releases the force on the second end of the seesaw 52, ​​and the elastic member 53 returns to its original state, so that the first end of the seesaw 52 blocks the movement of the partition 2. Preferably, the elastic member 53 is a spring. The seesaw driver is a cylinder and a pin plug (not shown in the figure), and the pin plug can be inserted into the bottom of the second end of the seesaw 52 under the push of the cylinder, thereby lifting the second end of the seesaw 52.

[0061] Specifically, the number of the stopper assembly 5 is one or more, and the number is not limited. For example, when there are two groups of stopper assemblies 5, the stopper assemblies 5 are located in the middle of the bottom plate 11 and at the end of the bottom plate 11 respectively.

[0062] See also Fig.11 and Fig.12 , Fig.11 It is a partial schematic diagram of the third embodiment of the battery fixture of the present application. Fig.12 yes Fig.11 Schematic diagram of the structure of B shown.

[0063] Combination Figure 1 and Figure 2 In this embodiment, the battery fixture further includes a positioning assembly 6, which can prevent the battery fixture from being easily merged under the action of external force when in an open state. Specifically, the positioning assembly 6 includes a positioning block 61 and a block driver 62. The positioning block 61 is provided with a plurality of positioning grooves 611 facing the partition 2. The block driver 62 drives the positioning block 61 to approach and move away from the plurality of partitions 2, so that when the plurality of partitions 2 are brought closer to each other and / or moved away from each other, the plurality of partitions 2 are respectively locked in the corresponding positioning grooves 611.

[0064] In actual process, when the guide sleeve 8 is provided on the slide rod hole 23, the size of the positioning groove 611 is matched to the size of the guide sleeve 8, and the positioning block 61 can be clamped on the guide sleeve 8, so that the position between the guide sleeves 8 does not change.

[0065] In order to accurately clamp the positioning assembly 6 on the plurality of partitions 2, the drive shaft of the block driver 62 is mounted on the connecting plate 63, and at least two guide shafts 64 are mounted on the connecting plate 63. The guide shafts 64 pass through the connecting plate 63 and are connected to the positioning block 61, wherein the guide shafts 64 are used to guide the positioning block 61. Preferably, the block driver 62 is a cylinder, and the drive shaft of the cylinder drives the connecting plate 63 to move.

[0066] See also Fig.13 , Fig.13 It is a side view of an embodiment of a baffle of the present application.

[0067] Combination Figure 1 In this embodiment, the cell fixture further includes a plurality of baffles 7, which are respectively arranged on the corresponding partitions 2, and the position and number of the baffles 7 correspond to the position and number of the partitions 2. The baffles 7 are used to support the exposed part of the cell between the partitions 2, and play the role of isolating adjacent cells. The baffles 7 are provided with avoidance grooves 71, and the opening direction of the avoidance grooves 71 points to the side of the baffles 7 away from the partition 2. The avoidance grooves 71 are used to allow the manipulator to grab the cell from the opposite sides of the cell.

[0068] The battery cell jig of this embodiment includes a bottom plate, a plurality of partitions and a flexible drag film. The plurality of partitions are arranged on the bottom plate at intervals along a preset direction, and the interval between the partitions is adjustable, so that when the partitions are close to each other, the battery cell can be clamped from opposite sides of the battery cell inserted between the partitions. The flexible drag film is at least partially arranged between the partitions, and is arranged in a concave shape along the insertion direction of the battery cell relative to the partition, so as to support the battery cell inserted between the partitions. By using the flexible drag film as the bottom support of the battery cell, it can expand and contract with the opening and closing of the battery cell jig, thereby reducing the wear of the bottom of the battery cell.
