Description

Technical Field

[0001] The present application relates to the field of battery cell technology, and in particular to an insulating support plate and a battery cell cover plate assembly. Background Art

[0002] The cover assembly is a key component of the battery cell, which is used to close the opening of the battery cell shell and plays the role of sealing, fixing and insulation.

[0003] The electrical cover assembly consists of a pole, an aluminum sheet, and a lower plastic sheet connected to the aluminum sheet. Both the aluminum sheet and the lower plastic sheet have pole mounting holes, into which the pole is installed. To insulate the pole from the aluminum sheet and seal the battery cell, a sealing ring is fitted onto the pole. Specifically, the pole passes through the lower plastic sheet, the sealing ring, and is secured within the pole mounting hole in the aluminum sheet.

[0004] However, the lower plastic of the current cover assembly still has obvious defects:

[0005] First, the lower plastic is very prone to deformation such as shrinkage, warping, and twisting after molding, which will cause the lower plastic to become skewed and offset after it is assembled with the cover to obtain the cover assembly. Furthermore, the cover assembly will be misaligned after assembly with the electrode group, which may make it impossible to wrap the insulating film. Severe misalignment may even cause the insulating film to wrinkle and tear, thereby affecting the insulation performance inside the battery cell and reducing the quality of the finished battery cell.

[0006] Second, the lower plastic will be twisted and deformed due to thermal expansion and contraction, which will cause the pole to shift, and in severe cases will cause the sealing ring to seal poorly. Summary of the Invention

[0059] Example 1

[0060] See also Figures 1 to 16As shown, an embodiment of the present application provides an insulating support plate 1 for a battery cell cover assembly 2. Specifically, the insulating support plate 1 is used to achieve insulation between the cover body 20 of the battery cell cover assembly 2 and the battery cell, and to support the pole group inside the battery cell.

[0061] The insulating support plate 1 provided in this embodiment includes an adjusting portion 11 and a support plate body.

[0062] The support plate body is provided with a slot which penetrates one side edge of the support plate body. That is, the slot opening is located at one side edge of the support plate body, and the slot does not penetrate the other side edge of the support plate body opposite to the side edge.

[0063] The support plate body includes a main body portion arranged on both sides of the slot, so that part of the side edges of two adjacent main body portions 10 are directly connected, and the other part of the side edges of the two are separated by the slot. The dotted line in the figure shows the direct connection between the two adjacent main body portions 10.

[0064] Two adjacent main bodies are connected within the slots via an adjustment portion, and the adjustment portion 11 is capable of deformation under load. In other words, depending on the number of slots, the main body 10 can be divided into at least two, for example, two, three, or more. Furthermore, by configuring the shape or material characteristics of the adjustment portion 11, the adjustment portion 11 can be configured to have the function of deformation under load.

[0065] After the insulating support plate 1 is formed or affected by environmental factors such as thermal expansion and contraction, it is easy to shrink, twist or warp and other deformations. The original shrinkage, twisting, warping and other deformations of the insulating support plate 1 can be adjusted and compensated by the force deformation of the adjustment part 11. Therefore, when assembling the insulating support plate 1 to the cover plate body 20, it is possible to prevent the insulating support plate 1 from being offset and skewed, thereby preventing misalignment with the pole group due to deformation, ensuring successful coating of the insulating film, and preventing wrinkles and tears in the insulating film. At the same time, it is also possible to prevent the pole from being offset due to deformation of the insulating support plate 1, ensure the sealing performance of the sealing ring, and improve the quality of the battery cover plate assembly 2 and the battery cell using the insulating support plate 1.

[0066] Optionally, the adjusting portion and the supporting plate body of the insulating supporting plate 1 are integrally injection-molded with insulating materials such as plastic. Specifically, they can be used as the lower plastic of the battery cover assembly 2 .

[0067] In an optional solution of this embodiment, along the groove depth direction of the groove, the ratio of the groove depth L1 of the groove to the total size L2 of the support plate body is 1 / 3-2 / 3, such as 1 / 3, 1 / 2 or 2 / 3.

[0068] By configuring the ratio of L1 to L2 to be no less than 1 / 3, the adjustment portion 11 in the slot can effectively play an adjustment compensation role. By configuring the ratio of L1 to L2 to be no more than 2 / 3, the insufficient strength of the support plate body caused by the slot being too large can be avoided.

[0069] In an optional solution of this embodiment, the adjusting portion 11 includes an adjusting rib 110 , and the adjusting rib 110 is curved, so that the degree of curvature of the adjusting rib 110 changes when it is subjected to force, thereby achieving deformation.

[0070] Specifically, by relatively pulling the two main bodies 10 connected by the adjusting rib 110, the two ends of the adjusting rib 110 are relatively far away from each other, thereby compensating for the shrinkage deformation of the insulating support plate 1; by pressing down the warped main body 10, one end of the adjusting rib 110 is pressed down along with the warped main body 10. Since the adjusting rib 110 can be deformed, the other end of the adjusting rib 110 and its non-warped main body 10 will not be pressed down and remain stationary, thereby compensating for the warping deformation of the insulating support plate 1; by relatively twisting the two main bodies 10 connected by the adjusting rib 110, the two ends of the adjusting rib 110 are relatively twisted, thereby compensating for the twisting deformation of the insulating support plate 1.

[0071] It is worth explaining that the adjustment rib 110 is configured to be bent, so that the relative position relationship between the two ends of the adjustment rib 110 can be changed by adjusting the bending degree of the adjustment rib 110 to achieve compensation for various deformations such as shrinkage, warping and twisting.

[0072] It is understandable that, depending on the deformation of the insulating support plate 1 itself, one or at least two of the above-mentioned deformation compensation solutions may be used alone or in combination.

[0073] In an optional solution of this embodiment, in order to make the adjustment rib 110 of the insulating support plate 1 have the characteristic of being able to deform, the adjustment rib 110 can also be configured to have elasticity.

[0074] In the optional solution of this embodiment, Figures 5 to 7 As shown, the adjustment rib 110 is bent toward the depth direction of the groove. In other words, the raised direction of the bent part of the adjustment rib 110 is toward the depth direction of the groove, wherein the depth direction of the groove can be the length direction, thickness direction or a composite direction of the support plate body.

[0075] Or, as Figures 1 to 4 As shown and Figures 9 to 16 As shown, the adjustment rib 110 is bent toward the thickness direction of the support plate body. In other words, the bulging direction of the bent portion of the adjustment rib 110 is toward the thickness direction of the support plate body.

[0076] Alternatively, the adjustment rib 110 is bent toward the depth direction of the groove and the thickness direction of the support plate body. In other words, the raised direction of the bent part of the adjustment rib 110 is toward both the depth direction of the groove and the thickness direction of the support plate body (not shown in the figure).

[0077] In this embodiment, the adjustment rib 110 is V-shaped, wave-shaped (not shown in the figure) or arc-shaped, wherein, for example Figures 1 to 4 As shown, the adjustment rib 110 is V-shaped and bent toward the thickness direction of the support plate body. When the adjustment rib 110 is V-shaped, the bending angle of the adjustment rib 110 is 0-180°, for example, 30°, 60°, 90°, 120°, 150° or 180°; Figures 5 to 8 As shown, the adjustment rib 110 is arc-shaped and bent toward the groove depth direction; Figures 9 to 16 As shown, the adjustment rib 110 is arc-shaped and bent toward the thickness direction of the support plate body. When the adjustment rib 110 is arc-shaped, the central angle corresponding to the arc is 0-180°, for example, 30°, 60°, 90°, 120°, 150° or 180°.

[0078] Optionally, the thickness of the adjustment rib 110 is configured to be smaller than the thickness of the insulating support plate 1 .

[0079] In an optional solution of this embodiment, the adjustment portion 11 includes one adjustment rib 110; or, the adjustment portion 11 includes multiple adjustment ribs 110, and the multiple adjustment ribs 110 are arranged at intervals along the groove depth direction of the slot.

[0080] Among them, such as Figure 11 As shown, when the adjustment portion 11 includes an adjustment rib 110 , the dimension of the adjustment rib 110 along the groove depth direction of the slot can be configured to be larger to prevent the adjustment rib 110 from breaking in the deformation compensation state.

[0081] When Figure 2 、 Figures 5 to 7 as well as Figure 10 As shown, when the adjustment portion 11 includes multiple adjustment ribs 110, the adjustment ribs 110 are configured to be smaller along the groove depth direction of the slot, so that by stacking multiple adjustment ribs 110 at intervals, the deformation posture of the adjustment portion 11 can be made more flexible and diverse while ensuring that the adjustment ribs 110 will not break in the deformation compensation state.

[0082] In an alternative embodiment of the present invention, there are multiple adjustment parts 11, all of which have the same shape, or at least two of which have different shapes. In other words, there can be one or more adjustment parts 11, such as two, three, or more.

[0083] When there are multiple adjusting parts 11, at least two adjusting parts 11 have different shapes, for example Figures 9 to 16 As shown, there are two adjusting parts 11, and the shapes of the two adjusting parts 11 are different; or, the shapes of all adjusting parts 11 are the same, as shown in FIG. Figures 1 to 8 As shown, there are two adjusting parts 11 , and the two adjusting parts 11 have the same shape.

[0084] In an optional solution of this embodiment, an adjustment portion 11 is provided on one side edge of the support plate body in the width direction and serves as a first adjustment portion 11a, and an adjustment portion 11 is provided on the other side edge of the support plate body in the width direction and serves as a second adjustment portion 11b.

[0085] The number of the first adjusting portion 11a and the number of the second adjusting portion 11b are both at least one. Figure 2 For example, the case where both the first adjustment portion 11a and the second adjustment portion 11b are one is shown. In order to improve the flexibility of compensating for deformation, the number of the first adjustment portion 11a and the second adjustment portion 11b can be appropriately increased according to demand.

[0086] In this embodiment, Figure 2 、 Figure 7 and Figure 12 As shown, the support plate body includes three main body parts 10 connected in sequence along the length direction of the support plate body.

[0087] The main body portion 10 located in the middle is provided with a safety valve vent hole 102 , which allows internal gas to communicate with the explosion-proof valve 25 .

[0088] A first adjustment portion 11a is provided between the central body portion 10 and an adjacent body portion 10, and a second adjustment portion 11b is provided between the central body portion 10 and another adjacent body portion 10. In other words, along the length of the support plate body, the first adjustment portion 11a is provided on one side of the safety valve vent 102, and the second adjustment portion 11b is provided on the other side of the safety valve vent 102, such that the first adjustment portion 11a and the second adjustment portion 11b are provided diagonally with respect to the safety valve vent 102.

[0089] This scheme of diagonally arranging the first adjustment portion 11a and the second adjustment portion 11b, on the basis of structural simplification, enables the insulating support plate 1 to not only compensate for the deformation at both ends in the length direction respectively, but also to perform diagonal adjustment compensation for the deformation of the insulating support plate 1, thereby improving the precision of the adjustment compensation.

[0090] Alternatively, the first regulating portion 11 a and the second regulating portion 11 b may be configured to be symmetrical about the center of the safety valve vent hole 102 .

[0091] In this embodiment, the insulating support plate 1 is provided with a pole through hole, which is used to install the pole. Specifically, the pole includes a first pole 21 and a second pole 22. One of the first pole 21 and the second pole 22 is a positive pole, and the other is a negative pole.

[0092] The pole through-holes on the insulating support plate 1 include a first pole mounting hole 100 and a second pole mounting hole 101 , wherein the first pole mounting hole 100 is used to mount the first pole 21 , and the second pole mounting hole 101 is used to mount the second pole 22 .

[0093] Example 2

[0094] Embodiment 2 provides a battery cell cover plate assembly, which includes the insulating support plate in embodiment 1. The technical features of the insulating support plate disclosed in embodiment 1 are also applicable to this embodiment, and the technical features of the insulating support plate disclosed in embodiment 1 will not be repeated.

[0095] Combine Figures 1 to 16 See also Figures 17 to 19 As shown, the cell cover plate assembly 2 provided in this embodiment includes an insulating support plate 1 , which serves as a lower plastic support below the cover plate body 20 .

[0096] Specifically, the battery cell cover assembly 2 also includes a cover body 20, a first sealing ring 23, a second sealing ring 24, a first pole 21 and a second pole 22. The cover body 20 can be a plain aluminum sheet. The cover body 20 is provided with two through holes for passing the first pole 21 and the second pole 22. The first sealing ring 23 is sleeved on the first pole 21 to perform a sealing and insulating role between the cover body 20 and the first pole 21. The second sealing ring 24 is sleeved on the second pole 22 to perform a sealing and insulating role between the cover body 20 and the second pole 22.

[0097] Optionally, the cell cover assembly 2 further includes an explosion-proof valve 25 and an explosion-proof valve patch 26. The cover body 20 is provided with an explosion-proof through-hole 200. When the cover body 20 is assembled with the insulating support plate 1, the explosion-proof through-hole 200 corresponds to the safety valve vent 102. The explosion-proof valve 25 is disposed within the explosion-proof through-hole 200, thereby enabling the explosion-proof valve 25 to contact the gas inside the cell via the safety valve vent 102, thereby providing an explosion-proof function. The explosion-proof valve patch 26 is mounted on top of the explosion-proof valve 25 to protect the explosion-proof valve 25 and prevent accidents such as accidental scratching or contamination of the explosion-proof valve 25.

[0098] The cell cover plate assembly in this embodiment has the advantages of the insulating support plate in the first embodiment, and the advantages of the insulating support plate disclosed in the first embodiment will not be repeated here.
