Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a clamp. Background Art

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0003] In related technologies, injecting electrolyte into battery cells typically requires significant pressure to force the electrolyte into the battery. This can cause deformation or displacement of the battery cells and the fixtures holding them due to the injection pressure. Deformation of the fixtures typically manifests as curling of the separator corners or loosening of the screws securing the separator, causing it to protrude from the separator surface. This can easily lead to a series of problems. Summary of the Invention

[0004] One object of the present application is to provide a clamp to improve the overall strength and stability of the clamp, thereby improving the problem of deformation and / or displacement of the partition in the clamp due to pressure.

[0005] An embodiment of the first aspect of the present application provides a clamp for a battery. The clamp includes an outer frame and a partition assembly. The outer frame includes two first side portions arranged along the length of the clamp, two second side portions arranged along the width of the clamp, and a bottom plate connecting the bottoms of the two first side portions and the bottoms of the two second side portions. The two first side portions are arranged at both ends of the clamp in the width direction, and the two second side portions are arranged at both ends of the clamp in the length direction. The partition assembly includes: N pairs of partitions, arranged between the two first side portions along the width direction of the clamp, the two partitions in each pair of partitions facing each other in the length direction, and used to clamp a corresponding battery cell, N is an integer greater than or equal to 1; N+1 partition support plates, alternately arranged with the N pairs of partitions in the length direction of the clamp, so that the side of each partition facing away from the battery cell abuts against a partition support plate; and multiple partition reinforcements, wherein each partition is provided with at least one partition reinforcement, each partition reinforcement passes through the partition along the width direction of the clamp, and extends beyond the partition to be detachably connected to the two first side portions.

[0006] In the technical solution of the embodiments of this application, the partition reinforcement is provided to improve the overall strength and stability of the partition. Due to the presence of the partition support plate and the partition reinforcement, the surface of the partition facing the battery cell does not need to be installed with screws for fixing the partition. This can alleviate the problem of partition deformation and / or displacement caused by pressure, for example, reducing the risk of damage to the battery cell casing due to curling corners or loose screws.

[0007] In some embodiments, the two first side portions each include a plurality of slide slots extending along the length, each slide slot being configured to accommodate one end of a corresponding partition reinforcement member, and one end of the corresponding partition reinforcement member is detachably connected to the slide slot. Providing slide slots on the first side portion of the fixture allows for stepless adjustment for battery cells of varying thickness specifications and enhances the flexibility of battery cell replacement.

[0008] In some embodiments, the N+1 separator support plates are selected from a variety of separator support plates of different thickness specifications, and the plurality of separator support plates of different thickness specifications are adapted to battery cells of different thicknesses. Depending on the thickness of the selected separator support plates, the spacing between the two separators in each pair of separators can be changed by changing the position of the end of the separator reinforcement in the chute, thereby enabling each pair of separators to clamp battery cells of corresponding thickness. By selecting appropriate separator support plates and adjusting the position of the separator reinforcement, the spacing between each pair of separators can be matched to the thickness of the clamped battery cells, increasing the flexibility of the clamp. Furthermore, the fact that no separator replacement is required during adjustment also reduces costs.

[0009] In some embodiments, the fixture further includes N pairs of side plates, each pair of side plates being disposed between a corresponding pair of separators in the N pairs of separators, with the two side plates in each pair of side plates facing each other in the width direction of the fixture. The two side plates and the corresponding pair of separators are used to define a receiving space for the corresponding battery cell clamped by the corresponding pair of separators. Providing the side plates in conjunction with the separators can improve the stability and safety of the battery cells during the injection process.

[0010] In some embodiments, each side panel of each pair of side panels is detachably connected to a corresponding side panel of the two first side portions. The detachable connection of the side panels of the clamp to the first side portions allows the side panels to be adjusted, replaced, or repaired as needed, thereby making the use of the clamp more flexible.

[0011] In some embodiments, the fixture further includes N spacers, each spacer positioned between a corresponding pair of the N pairs of spacers and on the bottom plate to support a corresponding battery cell held by the corresponding pair of spacers. The placement of spacers in the fixture can increase operational flexibility during battery cell injection.

[0012] In some embodiments, the N spacers are selected from a variety of spacers of varying heights to accommodate battery cells of varying heights. Depending on the selected spacer heights, the corresponding battery cell held by each pair of separators can be positioned at a predetermined height relative to the outer frame. The spacers in the fixture can provide an appropriate injection height for the battery cells being held.

[0013] In some embodiments, the base plate has openings at locations corresponding to the N pads. These openings allow a lifting device to pass through the base plate to lift the corresponding pads and the battery cells they carry. The openings in the base plate allow the lifting device to adjust the height of the battery cells in the fixture.

[0014] In some embodiments, a threaded hole is formed at the end of each partition reinforcement member, and is fixedly connected to the slide slot by a bolt passing through the slide slot. By using the bolt and the threaded hole, a detachable fixed connection between the partition reinforcement member and the slide slot can be achieved.

[0015] In some embodiments, each of the N pairs of side panels is formed with a threaded hole, and the two first side portions are provided with corresponding side panel mounting holes. The side panels are fixedly connected to corresponding side portions of the two first side portions via bolts extending through the side panel mounting holes. The use of bolts and threaded holes enables a removable fixed connection between the side panels and the first side portions, while reducing the risk of the battery cell housing being scratched by the protruding screws.

[0016] In some embodiments, the separator assembly comprises a non-metallic flexible material, and / or the separator reinforcement comprises a metal material. The non-metallic flexible material can reduce the risk of the separator contacting the battery cell and damaging the cell surface, while the metal separator reinforcement can provide the separator with greater rigidity.

[0017] In some embodiments, the base plate includes at least two positioning holes for mounting and positioning the fixture. Providing positioning holes in the base plate can provide a matching reference for positioning the fixture in different logistics positions.

[0018] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0037] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0038] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0042] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components.

[0043] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0044] In the related art, when injecting liquid into a battery cell, a large pressure is usually required to press the electrolyte into the battery. This will cause the battery cell and the clamp that clamps it to deform or shift due to the injection pressure. The deformation of the clamp is usually manifested as curling at the corners of the partition or the loosening of the screws that fix the partition. Specifically, whether it is a change in the internal pressure of the battery cell or a change in temperature, the partition will be deformed. The deformation generation and recovery process will generate a certain reciprocating axial force on the screws on the partition, and this axial force will cause the screws to loosen. In addition, the entire clamp will generate a certain amount of vibration every time it is moved and parked, thereby aggravating the loosening of the screws and causing them to protrude from the surface of the partition. After the screws are loosened, the partition will be permanently deformed due to the long-term influence of thermal expansion and contraction, and its corners will be raised.

[0045] This can easily lead to a series of problems. For example, in the process of taking and placing battery cells, the curled corners of the partition or the loose screws will scrape the outer shell of the battery cell, causing damage to the appearance or even the battery cell being scrapped. For another example, the deformation or displacement of the fixture causes the original space for accommodating battery cells to be reduced. When the space for the fixture to accommodate battery cells is reduced, when the battery cell is taken out of the fixture, the resistance it encounters increases, which will increase the risk of the battery cell being thrown off the clamp; when the battery cell is placed in the fixture, it may also collide with the curled corners of the partition or loose screws, causing a collision.

[0046] The clamp disclosed in the embodiment of the present application can improve the overall strength and stability of the partition in the clamp, and can improve the problem of deformation and / or displacement of the partition due to pressure.

[0048] An embodiment of the present application provides a clamp for a battery, comprising an outer frame 100 and a spacer assembly 200 .

[0049] The outer frame 100 includes two first side portions 110 arranged along the length direction L of the clamp, two second side portions 120 arranged along the width direction W of the clamp, and a bottom plate 130 connecting the bottoms of the two first side portions 110 and the bottoms of the two second side portions 120. The two first side portions 110 are arranged at both ends of the clamp in the width direction W, and the two second side portions 120 are arranged at both ends of the clamp in the length direction L.

[0050] The diaphragm assembly 200 includes N pairs of diaphragms 210 , N+1 diaphragm support plates 220 , and a plurality of diaphragm reinforcement members 230 .

[0051] N pairs of separators 210 are arranged between the two first side portions 110 along the width direction W of the clamp, and the two separators in each pair are opposite to each other in the length direction L for clamping a corresponding battery cell (not shown), where N is an integer greater than or equal to 1.

[0052] N+1 separator support plates 220 and N pairs of separators 210 are alternately arranged in the length direction L of the fixture, so that the side of each separator facing away from the battery cell abuts against one separator support plate 220 .

[0053] Each partition is provided with at least one partition reinforcement 230 . Each partition reinforcement 230 penetrates the partition along the width direction W of the clamp and extends beyond the partition to be detachably connected to the two first side portions 110 .

[0054] In the embodiments of the present application, a "clamp" may refer to a device for fixing, supporting, and protecting a battery or battery cell. The "clamp" in the present application may also specifically refer to a device for clamping a battery cell to inject electrolyte into the battery cell during the battery production process.

[0055] The outer frame 100 can provide a mounting point as well as stable support and protection for other components in the fixture (such as the partition assembly 200 ).

[0056] Inside the outer frame 100, N+1 separator support plates 220 and N pairs of separators 210 are alternately arranged along the length direction L. Among them, the N pairs of separators 210 can be used to separate the battery cells in the fixture, and each pair of separators (for example, Figure 1 or Figure 3 The first separator 210a and the second separator 210b in the separator pair can be used to clamp a corresponding battery cell, so that each battery cell can be independently injected. The separator support plate 220 can provide stable positional support for the separator against which it rests, and thus for the battery cell clamped between each pair of separators.

[0057] In an embodiment of the present application, the number of partitions can be one pair, and the number of partition support plates can be two (not shown in the figure); or, the number of partitions can be two or more pairs, and the number of partition support plates can be three or more.

[0058] For example, if there is only one pair of separators, the two separator support plates 220 are respectively arranged inside the outer frame 100 adjacent to the two second side portions 120 of the clamp. The two separators in the pair of separators respectively abut against the two separator support plates 220 and are arranged between the two first side portions 110 along the width direction W of the clamp. The space between the two separators in the pair of separators is used to clamp a battery cell.

[0059] In the case where the number of the partition pairs is two or more, the number of the partition support plates may be three or more. Figure 1 or Figure 3The embodiment shown in FIG. 1 shows a case where there are eight separator pairs and nine separator support plates, wherein two separator support plates 220 are respectively arranged inside the outer frame 100 adjacent to the two second side portions 120 of the clamp, and the remaining separator support plates 220 are sequentially arranged and spaced between the two separator support plates 220. Each pair of separators is arranged opposite each other along the width direction W of the clamp and respectively abuts against two adjacent separator support plates 220, wherein the space between the two separators in each pair is used to clamp a corresponding battery cell.

[0060] The partition assembly 200 further includes a plurality of partition reinforcements 230 . Each partition reinforcement 230 may be embedded in the partition and penetrate the partition in the width direction W. Portions of the partition reinforcements 230 extending beyond the partition may be detachably connected to the two first side portions 110 .

[0061] In the technical solution of the embodiments of this application, the partition reinforcement is provided to improve the overall strength and stability of the partition. Due to the presence of the partition support plate and the partition reinforcement, the surface of the partition facing the battery cell does not need to be installed with screws for fixing the partition. This can alleviate the problem of partition deformation and / or displacement caused by pressure, for example, reducing the risk of damage to the battery cell casing due to curling corners or loose screws.

[0062] According to some embodiments of the present application, the two first side portions 110 each include a plurality of slide grooves 112 extending along the length direction L, each slide groove 112 is used to accommodate one end of a corresponding partition reinforcement 230, and one end of a corresponding partition reinforcement 230 is detachably connected to the slide groove 112.

[0063] In some embodiments, reference Figure 3 The partition reinforcement 230 can be, for example, a rod, such as a stainless steel rod, with both ends extending beyond the partition and detachably connected to the chute 112. The number of partition reinforcements 230 in each partition can be, for example, three, thereby better increasing the overall rigidity of the partition.

[0064] In some embodiments, a plurality of slide grooves 112 may be provided at a certain height of each first side portion 110. This height may match the height of one bulkhead reinforcement 230 in the bulkhead to accommodate one end of the bulkhead reinforcement 230. When there are three bulkhead reinforcements 230 in each bulkhead, a plurality of slide grooves 112 may be provided at three corresponding heights of each first side portion 110 to accommodate each end of the three bulkhead reinforcements 230.

[0065] In some embodiments, the slide groove 112 may extend along the length direction L of the clamp. The slide groove 112 extending along the length direction L can provide multiple selectable installation positions along the length direction L for the bulkhead reinforcement 230 and thus for the bulkhead.

[0066] Providing a slide groove on the first side of the clamp can perform stepless adjustment for battery cells with different thickness specifications and enhance the flexibility of battery cell replacement.

[0067] According to some embodiments of the present application, the N+1 separator support plates 220 are selected from a variety of separator support plates of different thicknesses, each of which is adapted to battery cells of varying thicknesses. Depending on the thickness of the selected separator support plates, the spacing between the two separators in each pair of separators can be varied by changing the position of the end of the separator reinforcement 230 within the chute 112, thereby enabling each pair of separators to clamp battery cells of corresponding thicknesses.

[0068] In some embodiments, for example, reference Figure 1 or Figure 3 The spacer support plates at both ends of the fixture may have different thickness specifications than the spacer support plate in the middle. In some embodiments, the spacer support plates at both ends of the fixture may also have the same thickness specifications as the spacer support plate in the middle (not shown).

[0069] When clamping battery cells of different specifications, the separator support plate in the same fixture can also be replaced with another separator support plate with different thickness specifications. Depending on actual needs, the thickness of the separator support plate at any position in the fixture can be selected.

[0070] When the thickness of the diaphragm support plate is determined, the spacing between the two diaphragms in each pair of diaphragms abutting the diaphragm support plate can be changed by changing the position of the end of the diaphragm reinforcement 230 in the slide groove 112 .

[0071] By selecting appropriate separator support plates and adjusting the position of the separator reinforcements, the spacing between each pair of separators can be adjusted to match the thickness of the battery cells being clamped, increasing the flexibility of the clamp. Furthermore, the fact that separators do not need to be replaced during adjustments also reduces costs.

[0072] According to some embodiments of the present application, the clamp further includes N pairs of side plates 300, each pair of side plates being arranged between a corresponding pair of partitions in the N pairs of partitions 210, and the two side plates in each pair of side plates are opposite to each other in the width direction W of the clamp, and the two side plates and the corresponding pair of partitions are used to limit the accommodation space of the corresponding battery cells clamped by the corresponding pair of partitions.

[0073] In some embodiments, continue to refer to Figure 3 , one or more pairs of side plates 300 are provided, the same number as the N pairs of separators. The side plates and the corresponding pair of separators 210 form a clamping area capable of enclosing the side surfaces of the battery cell.

[0074] By providing the side plates in conjunction with the separators, the stability and safety of the battery cells during the liquid injection process can be improved.

[0075] According to some embodiments of the present application, each side panel in each pair of side panels is detachably connected to a corresponding side portion of the two first side portions 110 .

[0076] In some embodiments, continue to refer to Figure 3 Each pair of side panels may include a first side panel 300a and a second side panel 300b. Each side panel may be detachably connected to the corresponding first side portion 110, for example, using bolts, latches, buckles, etc.

[0077] The detachable connection between the side plate of the clamp and the first side portion allows the side plate to be adjusted, replaced or repaired as needed, thereby making the use of the clamp more flexible.

[0078] According to some embodiments of the present application, the clamp further includes N spacers 400 , each spacer being located between a corresponding pair of the N pairs of spacers 210 and on the bottom plate 130 to support a corresponding battery cell clamped by the corresponding pair of spacers.

[0079] In some embodiments, reference Figure 3 and Figure 6 A spacer block may be provided between each pair of spacers. The number of spacers in the fixture may depend on the number of spacer pairs in the fixture, for example, the same as the number of spacer pairs.

[0080] In some embodiments, the spacers are detachably arranged on the bottom plate 130 to support corresponding battery cells.

[0081] Arranging spacers in the fixture can increase the operational flexibility when injecting liquid into the battery cell.

[0082] According to some embodiments of the present application, the N spacers 400 are selected from a variety of spacers of varying heights, each of which is adapted to accommodate battery cells of varying heights. Depending on the selected spacer heights, the corresponding battery cell held by each pair of separators can be positioned at a predetermined height relative to the outer frame 100.

[0083] The pad 400 in the fixture can provide a suitable filling height for the battery cell it carries. For example, pads 400 with different height levels can be replaced for battery cells of different height specifications so that the battery cell can be set to a suitable filling height relative to the outer frame 100.

[0084] The spacers in the fixture can provide a suitable filling height for the battery cells it carries.

[0085] According to some embodiments of the present application, the bottom plate 130 is provided with an opening structure 132 at positions corresponding to the N pads 400 . The opening structure 132 allows a lifting device to pass through the bottom plate 130 to lift the corresponding pads and the battery cells supported by the pads.

[0086] In some embodiments, reference Figure 5 and Figure 6 The opening structure 132 is provided to facilitate the use and operation of the lifting device. The lifting device can lift the cushion block 400 and the battery cell carried by the cushion block 400 to a suitable position through the opening structure 132 on the bottom plate 130, or lower them to the bottom plate when necessary.

[0087] The shape and size of the opening structure 132 can be determined according to the requirements of the lifting device. Figure 5 In the embodiment shown, the opening structure 132 is shown as a slot, it should be understood that other opening structures that adapt to the shape and size of the lifting device are also possible.

[0088] The opening structure on the bottom plate allows the lifting device to adjust the height of the battery cell in the fixture.

[0089] According to some embodiments of the present application, a threaded hole is formed at the end of a corresponding partition reinforcement 230 and is fixedly connected to the slide groove 112 by a bolt passing through the slide groove 112 .

[0090] In some embodiments of the present application, a threaded hole (not shown in the figure) may be formed at the end of each partition reinforcement 230, and a bolt (not shown in the figure) may be arranged to pass through the slide groove 112. The partition reinforcement 230 in the partition can be fixed to the slide groove 112 by matching the threaded hole and the bolt of the slide groove 112.

[0091] By using bolts and threaded holes, a detachable fixed connection between the bulkhead reinforcement and the slide channel can be achieved.

[0092] According to some embodiments of the present application, each side panel of the N pairs of side panels 300 is formed with a threaded hole 310, and the two first side portions 110 are provided with corresponding side panel mounting holes 114, and the side panels are fixedly connected to the corresponding side portions of the two first side portions 110 by bolts passing through the side panel mounting holes 114.

[0093] Similarly, each of the N pairs of side panels 300 may also be formed with a threaded hole 310 to cooperate with the side panel mounting hole 114 opened in the first side portion 110 .

[0094] refer to Figure 3 、 Figure 6 and Figure 7 Taking the first side plate 300a as an example, one or more threaded holes 310 may be formed at one or more heights of the first side plate 300a. In some examples, the threaded holes 310 may be formed on a nut detachably connected to the body of the side plate, and a mounting hole corresponding to the threaded hole 310 may be formed on the side wall of the body of the side plate facing the threaded hole 310 ( Figure 7 In some examples, the threaded holes 310 may be formed directly on the body of the side panel (not shown). In either case, the first side portion 110 is provided with side panel mounting holes 114 corresponding to the one or more threaded holes 310. The first side panel 300a may be fixedly connected to the corresponding side portion of the two first side portions 110 by bolts (not shown) passing through the side panel mounting holes 114.

[0095] By using the bolts and the threaded holes, a detachable fixed connection between the side plate and the first side portion can be achieved, while reducing the risk of the battery cell housing being scratched by the protruding screws.

[0096] According to some embodiments of the present application, the material of the diaphragm assembly 200 includes a non-metallic flexible material, and / or the material of the diaphragm reinforcement 230 includes a metal material.

[0097] In related technologies, the battery cells before liquid injection usually have a relatively high temperature, and the parts of the fixture that contact the battery cells are usually made of corrosion-resistant non-metallic materials with limited temperature resistance. These materials will produce a certain thermal expansion and contraction effect due to the temperature changes of the battery cells, thereby exacerbating the deformation of the fixture.

[0098] In some embodiments of the present application, the material of the partition assembly 200 can be, for example, a corrosion-resistant, mechanically excellent, and high-temperature resistant polymer resin material, thereby reducing deformation of the fixture due to thermal expansion and contraction. In some embodiments, the material of the partition reinforcement 230 can be, for example, stainless steel.

[0099] The material of the separator assembly includes a non-metallic flexible material to reduce the risk of the separator contacting the battery cell and damaging the surface of the battery cell. The separator reinforcement includes a metal material to provide the separator with stronger rigidity.
