Description

Technical Field

[0001] The present disclosure relates to the technical field of new energy batteries, and in particular to an integrated heat insulation sheet and a battery pack structure. Background Art

[0002] With the development of new energy technology, new energy batteries have also developed rapidly, and vehicles powered by battery packs have become the first choice for more and more people. However, when the battery pack is in use, the high external temperature can easily cause overheating inside the battery pack, which can easily cause safety problems such as explosion and aging.

[0003] In order to prevent the battery from being affected by external temperature changes, most manufacturers usually stick a heat shield on each side of the battery pack, which means that a single battery pack needs to use a large number of heat shields. The large number of heat shields leads to more operating procedures and more operators, which is not conducive to production line operations. In response to this problem, some manufacturers have made further research and development.

[0004] For example, Chinese patent document CN206022580U discloses a battery insulation pad, including an upper gasket and a side gasket, the lower end of the upper gasket is fixedly connected to the side gasket, the side gasket is provided with a plurality of vertical fold lines, the plurality of vertical fold lines enable the side gasket to be folded into a cylinder with an upper opening and a lower opening, the upper gasket can close the upper opening of the cylinder, the left end of the side gasket has a clamping portion, the right end of the side gasket is provided with a clamping groove, the upper end and / or the lower end of the clamping portion can be bent toward the middle thereof, and the bent clamping portion can pass through the clamping groove to connect the left end of the side gasket with the right end.

[0005] However, the design of the above-mentioned battery insulation pad has the following problems:

[0006] The above-mentioned battery insulation pad can quickly wrap the entire battery by bonding the upper pad to the battery, but the pads are easily displaced during the bonding process. Since the pads are connected as a whole, when one of the pads is displaced, the other pads will also be displaced, which will eventually lead to the battery being not tightly wrapped and reduce the insulation effect. At the same time, when the pads are displaced during bonding, it is difficult to make a secondary adjustment because the pads are tightly bonded to the battery. Utility Model Content

DETAILED DESCRIPTION

[0034] In order to facilitate the understanding of the present disclosure, the present disclosure will be described more fully below with reference to the relevant drawings.

However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present disclosure more thoroughly and comprehensively understood.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0038] like Figure 1 and Figure 2 As shown, an integrated thermal insulation sheet 100 of an embodiment includes a first fitting gasket 110, an intermediate gasket 120 and a second fitting gasket 130 arranged in sequence; both side edges of the intermediate gasket 120 are respectively connected to the first fitting gasket 110 and the second fitting gasket 130; a plurality of alignment holes 1110 are provided on the first fitting gasket 110; a first adhesive area 1170 is provided on the first fitting gasket 110, and the first adhesive area 1170 is used to bond the first electrode end surface 210 of the battery pack 200; a plurality of alignment holes 1110 are spaced apart at the edge of the first adhesive area 1170, and each alignment hole 1110 is used to adapt to the positioning column 2110 of the first electrode end surface 210 of the corresponding battery pack 200.

[0039] It can be understood that by arranging multiple alignment holes 1110 at intervals on the edge of the first adhesive area 1170, when the first adhesive area 1170 is bonded to the first electrode end surface 210 of the battery pack 200, the alignment can be achieved through the one-to-one cooperation between the alignment holes 1110 and the positioning columns 2110 of the first electrode end surface 210 of the battery pack 200, so that the first adhesive area 1170 can be accurately bonded to the first electrode end surface 210 of the battery pack 200. When the first bonding gasket 110 is accurately bonded, the middle gasket 120 and the second bonding gasket 130 can also cover the battery pack 200 more accurately. Compared with the battery insulation pad in the prior art, the first fitting gasket 110 of the above-mentioned integrated insulation sheet 100 can be accurately aligned with the first electrode end surface 210 of the battery pack 200, so that the first adhesive area 1170 can be more accurately adhered to the first electrode end surface 210 of the battery pack 200, which can effectively reduce the pasting deviation and secondary adjustment, and finally make the first fitting gasket 110, the middle gasket 120 and the second fitting gasket 130 tightly cover the battery pack 200, thereby improving the thermal insulation effect of the battery pack 200.

[0040] Combination Figure 1As shown, specifically, the plurality of alignment holes 1110 are divided into two rows, namely the first alignment row 1111 and the second alignment row 1112; the first alignment row 1111 and the second alignment row 1112 are respectively arranged on the opposite sides of the first adhesive region 1170. It can be understood that since the first alignment row 1111 and the second alignment row 1112 are respectively arranged on the opposite sides of the first adhesive region 1170, by making the alignment holes 1110 in the first alignment row 1111 fit with the corresponding positioning posts 2110, and making the alignment holes 1110 in the second alignment row 1112 fit with the corresponding positioning posts 2110, both sides of the first adhesive region 1170 can be more accurately aligned with the first electrode end surface 210 of the battery pack 200, thereby making the first bonding gasket 110 as a whole bonded to the first electrode end surface 210 flat and accurate.

[0041] Combination Figure 1 As shown, further, the first alignment row 1111 includes a first alignment hole 111 a and a second alignment hole 111 b ; the first alignment hole 111 a is disposed close to the middle gasket 120 , and the second alignment hole 111 b is disposed away from the middle gasket 120 . It can be understood that by arranging the first alignment hole 111a close to the middle gasket 120, when the first alignment hole 111a is adapted to the corresponding positioning column 2110, the portion of the first fitting gasket 110 close to the middle gasket 120 can be accurately aligned with the first electrode end surface 210, and by arranging the second alignment hole 111b away from the middle gasket 120, when the second alignment hole 111b is adapted to the corresponding positioning column 2110, the portion of the first fitting gasket 110 away from the middle gasket 120 can be accurately aligned with the first electrode end surface 210, and finally the side of the first adhesive area 1170 where the first alignment row 1111 is located is better aligned with the first electrode end surface 210 of the battery pack 200.

[0042] Combination Figure 1As shown, in another embodiment, the second alignment row 1112 includes a third alignment hole 111c and a fourth alignment hole 111d; the third alignment hole 111c is disposed close to the middle gasket 120, and the fourth alignment hole 111d is disposed away from the middle gasket 120. It can be understood that by arranging the third alignment hole 111c close to the middle gasket 120, when the third alignment hole 111c is adapted to the corresponding positioning column 2110, the portion of the first fitting gasket 110 close to the middle gasket 120 can be accurately aligned with the first electrode end surface 210, and by arranging the fourth alignment hole 111d away from the middle gasket 120, when the fourth alignment hole 111d is adapted to the corresponding positioning column 2110, the portion of the first fitting gasket 110 away from the middle gasket 120 can be accurately aligned with the first electrode end surface 210, and finally the side of the first adhesive area 1170 where the second alignment row 1112 is located is better aligned with the first electrode end surface 210 of the battery pack 200.

[0043] Combination Figure 2 and Figure 3 As shown, in one embodiment, the first fitting gasket 110 is further provided with a center alignment ring 1120 at the center position of the first adhesive region 1170, and the center alignment ring 1120 is used to cooperate with the center boss 2120 of the first electrode end surface 210 of the battery pack 200. It can be understood that when the center alignment ring 1120 cooperates with the center boss 2120 of the first electrode end surface 210 of the battery pack 200, the center position of the first adhesive region 1170 can be more accurately adhered to the first electrode end surface 210, and it is less likely to be offset in the pasting.

[0044] like Figure 2 As shown, in this embodiment, the middle gasket 120 is provided with a first adhesive portion 1210, a glue-killing covering area 1240 and a second adhesive portion 1220 arranged in sequence; the glue-killing covering area 1240 is used to cover the protection plate 230 of the battery pack 200, the first adhesive portion 1210 is used to be bonded to the first end of the battery cell holder 240 of the battery pack 200, and the second adhesive portion 1220 is bonded to the second end of the battery cell holder 240 of the battery pack 200. It can be understood that by making the glue-killing covering area 1240 cover the protection plate 230 of the battery pack 200, making the first adhesive portion 1210 bonded to the first end of the battery cell holder 240 of the battery pack 200, and making the second adhesive portion 1220 bonded to the second end of the battery cell holder 240 of the battery pack 200, the glue-killing covering area 1240 is more firmly covered on the protection plate 230. At the same time, since the glue-killing covering area 1240 is not backed by glue, a heat dissipation gap can be formed between the glue-killing covering area 1240 and the protection plate 230. The heat of the protection plate 230 can be transferred faster through the air in the heat dissipation gap, thereby accelerating the heat dissipation of the protection plate 230.

[0045] like Figure 1 and Figure 2 As shown, further, the first fitting gasket 110 is connected to the first side of the glue-killing covering area 1240, and the first side of the glue-killing covering area 1240 is provided with a first indentation folding line 1140. It can be understood that by providing the first indentation folding line 1140 at the first side of the glue-killing covering area 1240, when the first fitting gasket 110 is bonded to the first electrode end surface 210 through the first adhesive area 1170, the glue-killing covering area 1240 can be folded along the first indentation folding line 1140 and covered on the protective plate 230. After the glue-killing covering area 1240 is folded along the first indentation folding line 1140, it can ensure that the first side of the glue-killing covering area 1240 is attached flat to the protective plate 230, avoiding the occurrence of arching at the first side of the glue-killing covering area 1240, and finally improving the wrapping between the integrated thermal insulation gasket of the present disclosure and the battery pack 200.

[0046] Combination Figure 1 and Figure 2 As shown, it can also be that, in another embodiment, the second fitting gasket 130 is connected to the second side of the glue-killing covering area 1240, and a second indentation folding line 1310 is provided at the second side of the glue-killing covering area 1240. It can be understood that by setting the second indentation folding line 1310 at the second side of the glue-killing covering area 1240, when the glue-killing covering area 1240 is covered on the protective plate 230, the second fitting gasket 130 can be folded along the second indentation folding line 1310 and attached to the second electrode end surface 220. After the second fitting gasket 130 is folded along the second indentation folding line 1310, it can ensure that the second side of the glue-killing covering area 1240 is attached flat to the protective plate 230, avoiding the occurrence of arching at the second side of the glue-killing covering area 1240, and finally improving the wrapping between the integrated thermal insulation gasket of the present disclosure and the battery pack 200.

[0047] Combination Figure 1 and Figure 2 As shown, specifically, the glue-killing covering area 1240 is provided with a plurality of alignment openings 1230, and the alignment openings 1230 are used to match the positioning blocks 2410 of the battery cell holder 240 of the battery pack 200. It can be understood that by providing a plurality of alignment openings 1230 on the glue-killing covering area 1240, when the glue-killing covering area 1240 covers the protective plate 230, the alignment openings 1230 can match the positioning blocks 2410 of the battery cell holder 240 of the battery pack 200, thereby making the glue-killing covering area 1240 cover the protective plate 230 more accurately. At the same time, since the alignment openings 1230 on the glue-killing covering area 1240 are limited by the positioning blocks 2410 of the battery cell holder 240, the relative slippage and displacement between the glue-killing covering area 1240 and the protective plate 230 can be effectively avoided.

[0048] Combination Figure 2and Figure 3 As shown, in one embodiment, the first laminating gasket 110 is provided with a plurality of pressure relief and heat dissipation holes 1130 at intervals in the first adhesive region 1170; the pressure relief and heat dissipation holes 1130 are used to correspond one-to-one with the cell electrode ends 2130 of the first electrode end surface 210 of the battery pack 200. It can be understood that by providing the pressure relief and heat dissipation holes 1130 on the first adhesive region 1170, since the pressure relief and heat dissipation holes 1130 correspond one-to-one with the cell electrode ends 2130 of the first electrode end surface 210 of the battery pack 200, the heat generated by a single cell during operation can be discharged in time through the corresponding pressure relief and heat dissipation holes 1130, thereby accelerating the heat dissipation of the entire battery pack 200. At the same time, when the electrode end of a single cell expands and leaks electrolyte, the electrolyte can flow out in time through the corresponding pressure relief and heat dissipation holes 1130, which can effectively prevent the entire battery pack 200 from swelling.

[0049] like Figure 2 As shown, the second adhesive region 1320 is provided on the second fitting gasket 130, and the second adhesive region 1320 is used to adhere the second electrode end surface 220 of the battery pack 200. It can be understood that by providing the second adhesive region 1320 on the second fitting gasket 130, the second fitting gasket 130 can be adhered to the second electrode end surface 220 of the battery pack 200 through the second adhesive region 1320, and finally the integrated thermal insulation gasket can wrap the battery pack 200 more tightly.

[0050] like Figure 4 As shown, the present disclosure also provides a battery pack structure, including a battery pack 200 and an integrated heat insulating sheet 100 of any of the above embodiments; a plurality of positioning posts 2110 are provided on the first electrode end surface 210 of the battery pack 200; a first adhesive region 1170 is attached to the first electrode end surface 210 of the battery pack 200; and the alignment holes 1110 are matched one by one with the positioning posts 2110. It can be understood that by applying the disclosed battery pack structure to a battery, the first adhesive region 1170 can be more accurately attached to the first electrode end surface 210 of the battery pack 200 by accurately aligning the first adhesive gasket 110 with the first electrode end surface 210 of the battery pack 200, thereby effectively reducing the situation of offset attachment and secondary adjustment, and finally making the first adhesive gasket 110, the middle gasket 120 and the second adhesive gasket 130 tightly cover the battery pack 200, thereby improving the heat insulation effect of the battery pack 200.

[0051] Compared with the prior art, the present invention has at least the following advantages:

[0052] The above-mentioned integrated thermal insulation sheet 100 has multiple alignment holes 1110 spaced apart at the edge of the first adhesive area 1170. When the first adhesive area 1170 is attached to the first electrode end surface 210 of the battery pack 200, the alignment holes 1110 can be matched one by one with the positioning columns 2110 of the first electrode end surface 210 of the battery pack 200 to achieve alignment, so that the first adhesive area 1170 can be accurately attached to the first electrode end surface 210 of the battery pack 200. When the first fitting gasket 110 is accurately attached, the middle gasket 120 and the second fitting gasket 130 can also cover the battery pack 200 more accurately. Compared with the battery insulation pad in the prior art, the first fitting gasket 110 of the above-mentioned integrated insulation sheet 100 can be accurately aligned with the first electrode end surface 210 of the battery pack 200, so that the first adhesive area 1170 can be more accurately adhered to the first electrode end surface 210 of the battery pack 200, which can effectively reduce the pasting deviation and secondary adjustment, and finally make the first fitting gasket 110, the middle gasket 120 and the second fitting gasket 130 tightly cover the battery pack 200, thereby improving the thermal insulation effect of the battery pack 200.

[0053] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be subject to the attached claims.
