Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a glue injection assembly for a battery pack, a battery pack, and an electrical device. Background Technology

[0002] Existing battery packs include a tray and a cell module located inside the tray, with a side panel on the side of the cell module. A PP (Polypropylene) sheet and a vacuum foam strip are sequentially disposed between the side panel and the inner wall of the tray. The vacuum foam strip is adhered to the inner wall of the tray, a first side of the PP sheet is adhered to the vacuum foam strip, and a second side of the PP sheet, opposite to the first side, is connected to the side panel. The PP sheet, the vacuum foam strip, and the inner wall of the tray together form an adhesive injection cavity, which is filled with adhesive.

[0003] However, the above structure makes the battery pack complex. The PP sheet is pasted on the side plate without clear positioning. It is difficult to automatically identify the position of the glue injection port during glue filling, which requires manual alignment of the glue injection port, thus increasing labor costs and resulting in low production efficiency of the battery pack.

[0059] Thirdly, this application provides an electrical device, which includes the glue injection assembly described in any of the first aspects or the battery pack described in any of the second aspects.

[0060] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0061] Since the battery pack includes a tray and cell modules, the tray has a placement cavity in which the cell modules are placed. This creates a gap between the cell modules and the tray, which can accommodate the injection molding assembly. Specifically, the support for the injection molding assembly is located between the side wall of the cell module and the inner wall of the placement cavity.

[0062] Because the glue injection assembly includes a support member adapted to enclose the tray and form a glue injection space, this support member replaces the assembly of the side plate and PP sheet compared to the prior art, which uses vacuum foam strips adhered to the inner wall of the tray, a first side of a PP sheet adhered to the vacuum foam strip, and a second side of the PP sheet opposite to the first side connected to a side plate, with the PP sheet, vacuum foam strip, and inner wall of the tray enclosing the glue injection cavity. This simplifies the battery pack structure, thereby improving battery pack production efficiency and reducing production costs.

[0063] Because this support component has an adhesive inlet channel that communicates with the adhesive injection space, it offers advantages over existing technologies where the first side of a PP sheet is adhered to a vacuum foam strip, and the second side of the PP sheet, opposite the first side, is connected to the side plate. Since this adhesive inlet channel is an integral part of the support component, its location can be accurately determined simply by identifying the support component. This makes the adhesive inlet channel easier to identify during adhesive injection, achieving automated adhesive injection and eliminating the need for manual alignment, thus further reducing battery pack production costs.

[0064] Because the support is adapted to form an outlet with the tray, and this outlet is connected to the glue injection space, the gas in the glue injection space can be smoothly discharged when glue is injected through the glue inlet channel, thereby increasing the glue injection rate and further improving the production efficiency of the battery pack.

Detailed Implementation

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0073] With the rapid development of electric vehicles, on-board battery packs have become an important component of automobiles. Existing battery packs include a tray and cell modules located inside the tray, with side panels on the sides of the cell modules. A PP (Polypropylene) sheet and a vacuum foam strip are sequentially arranged between the side panel and the inner wall of the tray. The vacuum foam strip is adhered to the inner wall of the tray, and the first side of the PP sheet is adhered to the vacuum foam strip. The second side of the PP sheet, opposite to the first side, is connected to the side panel. The PP sheet, the vacuum foam strip, and the inner wall of the tray together form an adhesive injection cavity, which is filled with adhesive.

[0074] However, the above structure makes the battery pack complex. The PP sheet is pasted on the side plate without clear positioning. It is difficult to automatically identify the position of the glue injection port during glue filling, which requires manual alignment of the glue injection port, thus increasing labor costs and resulting in low production efficiency of the battery pack.

[0075] To address the aforementioned technical issues, the battery pack provided in this application includes a tray and a cell module. The tray has a placement cavity, and the cell module is disposed within the placement cavity. This allows a gap to be formed between the cell module and the tray, which can accommodate an injection molding assembly. Specifically, the support member of the injection molding assembly is disposed between the side wall of the cell module and the inner wall of the placement cavity.

[0076] The glue injection assembly provided in this application includes a support member adapted to enclose a tray to form a glue injection space. Compared to the prior art, which uses vacuum foam strips adhered to the inner wall of the tray, a first side of a PP sheet adhered to the vacuum foam strip, and a second side of the PP sheet opposite to the first side connected to a side plate, with the PP sheet, vacuum foam strip, and inner wall of the tray enclosing the glue injection cavity, this support member replaces the assembly of the side plate and the PP sheet. This simplifies the battery pack structure, thereby improving battery pack production efficiency and reducing production costs.

[0077] Because this support component has an adhesive inlet channel that communicates with the adhesive injection space, it offers advantages over existing technologies where the first side of a PP sheet is adhered to a vacuum foam strip, and the second side of the PP sheet, opposite the first side, is connected to the side plate. Since this adhesive inlet channel is an integral part of the support component, its location can be accurately determined simply by identifying the support component. This facilitates automatic adhesive injection, eliminating the need for manual alignment and further reducing battery pack production costs.

[0078] Because the support is adapted to form an outlet with the tray, and this outlet is connected to the glue injection space, the gas in the glue injection space can be smoothly discharged when glue is injected through the glue inlet channel, thereby increasing the glue injection rate and further improving the production efficiency of the battery pack.

[0079] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0080] The following provides a detailed description of the specific structure of the above-mentioned glue injection component 11 and various possible implementation methods.

[0081] Figure 1 This is a schematic diagram of the structure of a support member 110 for an adhesive injection assembly 11 provided in an embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the structure of the glue injection assembly 11 installed in the battery pack 100. Figure 3 for Figure 2 A three-dimensional structural diagram of the dispensing component 11 in the diagram. Figure 4This is a partial cross-sectional view of a battery pack 100 provided in an embodiment of this application, formed by cutting a plane perpendicular to the tray bottom plate 122.

[0082] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a tray 120 and a cell module 140. The tray 120 has a placement cavity 121, and the cell module 140 is disposed within the placement cavity 121. The glue injection assembly 11 for the battery pack 100 includes a support member 110, which has a glue inlet channel 1101 and is disposed between the tray 120 and the cell module 140. The support member 110 is adapted to enclose with the tray 120 to form a glue injection space 150 and a discharge port 160. Both the glue inlet channel 1101 and the discharge port 160 communicate with the glue injection space 150.

[0083] In this embodiment, the battery pack 100 includes a tray 120 and a cell module 140. The tray 120 has a placement cavity 121, and the cell module 140 is disposed within the placement cavity 121. This creates a gap between the cell module 140 and the tray 120, which can accommodate the injection assembly 11. Specifically, the support member 110 of the injection assembly 11 is disposed between the side wall of the cell module 140 and the inner wall of the placement cavity 121.

[0084] Since the glue injection assembly 11 includes a support member 110, which is adapted to enclose the tray 120 to form a glue injection space 150, compared to the prior art, which uses vacuum foam strips adhered to the inner wall of the tray 120, a first side 1102 of a PP sheet adhered to the vacuum foam strip, and a second side 1103 of the PP sheet opposite to the first side 1102 connected to a side plate, with the PP sheet, vacuum foam strip, and inner wall of the tray 120 enclosing the glue injection cavity, this support member 110 replaces the assembly of the side plate and the PP sheet. This simplifies the structure of the battery pack 100, thereby improving the production efficiency of the battery pack 100 and reducing its production cost.

[0085] Because the support member 110 has an adhesive inlet channel 1101 that communicates with the adhesive injection space 150, compared to the prior art where the first side 1102 of the PP sheet is adhered to a vacuum foam strip and the second side 1103 of the PP sheet, which is opposite to the first side 1102, is connected to the side plate, the adhesive inlet channel 1101 is part of the support member 110. Therefore, as long as the position of the support member 110 can be identified, the position of the adhesive inlet channel 1101 can be accurately located. This makes the adhesive inlet channel 1101 easier to identify during adhesive injection, thus achieving automatic adhesive injection and eliminating the need for manual alignment, thereby further reducing the production cost of the battery pack 100.

[0086] Since the support member 110 is adapted to enclose the tray 120 to form an outlet 160, which is connected to the glue injection space 150, the gas in the glue injection space 150 can be smoothly discharged when glue is injected into the glue injection space 150 through the glue inlet channel 1101, thereby increasing the glue injection rate and further improving the production efficiency of the battery pack 100.

[0087] It should be noted that the side of the support member 110 facing away from the injection space 150 is connected to the cell module 140. In this way, the cell module 140 and the tray 120 can be fixedly connected by the adhesive member 1100 in the injection space 150 to improve the overall structural stability of the battery pack 100.

[0088] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The glue injection assembly 11 includes a seal 130, which is adapted to be disposed between the support 110 and the tray 120. The support 110, the seal 130 and the tray 120 enclose a glue injection space 150 and a discharge port 160.

[0089] In this way, the inner surface of the glue injection space 150 is sealed except for the glue inlet channel 1101 and the outlet 160. Therefore, when liquid adhesive is injected into the glue injection space 150 through the glue inlet channel 1101, it prevents the liquid adhesive from flowing out of the glue injection space 150, thus avoiding adverse effects of the liquid adhesive on other parts of the battery pack 100, and ensuring that a dense adhesive component 1100 is ultimately formed.

[0090] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The tray 120 includes a seal 130; the support 110 is adapted to enclose the tray 120 and the seal 130 to form an injection space 150 and an outlet 160.

[0091] In this way, the inner surface of the glue injection space 150 is sealed except for the glue inlet channel 1101 and the outlet 160. Therefore, when liquid adhesive is injected into the glue injection space 150 through the glue inlet channel 1101, it prevents the liquid adhesive from flowing out of the glue injection space 150, thus avoiding adverse effects of the liquid adhesive on other parts of the battery pack 100, and ensuring that a dense adhesive component 1100 is ultimately formed.

[0092] In addition, both the dispensing assembly 11 including the seal 130 and the tray 120 including the seal 130 can form the dispensing space 150 by combining two components. Compared with the solution of forming the dispensing space 150 by combining three components, the dispensing efficiency can be improved, thereby improving the production efficiency of the battery pack 100.

[0093] It should be noted that when connecting the support member 110 and the tray 120 to form the glue injection space 150, the sealant 130 can be pre-adheded to the inner wall of the tray 120 with adhesive backing, and then the support member 110 can be adhered to the sealant 130 to form the glue injection space 150; or the sealant 130 can be pre-adheded to the support member 110 with adhesive backing, and then the inner wall of the tray 120 can be adhered to the sealant 130 to form the glue injection space 150.

[0094] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The seal 130 includes a sealing segment 131 that forms an annular shape with an opening. The two ends of the sealing segment 131 are spaced apart along its length to form corresponding openings. The support 110 is adapted to enclose the tray 120 and the seal 130 at the opening to form a discharge port 160.

[0095] In this embodiment, the seal 130 includes a sealing segment 131, which forms an annular shape with an opening. This facilitates the sealing segment 131 in forming the injection space 150. Therefore, the number of discharge ports is one.

[0096] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The seal 130 includes a plurality of sealing segments 131, which are spaced apart to form an annular structure; an opening is formed between each pair of adjacent sealing segments 131, and the plurality of sealing segments 131 form a plurality of openings. The support 110 is adapted to enclose the tray 120 and the seal 130 at the opening to form an outlet 160.

[0097] In this embodiment, since multiple sealing segments 131 are arranged at intervals to form a ring structure, it is convenient for the sealing segments 131 to enclose and form the glue injection space 150. Since the sealing member 130 includes multiple sealing segments 131, an opening is formed between each pair of adjacent sealing segments 131, and the multiple sealing segments 131 form multiple openings. The support member 110 is adapted to enclose the tray 120 and the sealing member 130 at the opening to form an outlet 160. At this time, there are multiple outlets 160, so when glue is injected into the glue injection space 150 through the glue inlet channel 1101, the speed of gas discharge in the glue injection space 150 can be increased, thereby further increasing the glue injection rate, and thus further improving the production efficiency of the battery pack 100.

[0098] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The seal 130 includes two sealing segments 131, which are spaced apart to form an annular structure; the two sealing segments 131 form two openings. The support 110 is adapted to enclose the tray 120 and the seal 130 at the openings to form an outlet 160.

[0099] In this embodiment, since the two sealing segments 131 are arranged at intervals to form a ring structure, it is convenient for the sealing segments 131 to enclose and form the glue injection space 150. Since the seal 130 includes two sealing segments 131 arranged at intervals in a ring, the two sealing segments 131 form two openings. The support member 110 is adapted to enclose the tray 120 and the seal 130 at the openings to form an outlet 160. At this time, there are two outlets 160. In this way, when glue is injected into the glue injection space 150 through the glue inlet channel 1101, the rate of gas discharge in the glue injection space 150 can be increased, thereby further increasing the glue injection rate, and thus further improving the production efficiency of the battery pack 100.

[0100] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The seal 130 includes vacuum foam.

[0101] Since vacuum foam is an elastic and flexible material, when it is sandwiched between the support plate and the tray 120, it will undergo elastic deformation due to compression, thus achieving a better sealing effect.

[0102] The vacuum foam is compressed before bonding. During bonding, it needs to be expanded to a vacuum-free state before bonding. The thickness of the vacuum foam in the compressed state and the thickness in the expanded state are determined according to the design of the battery pack 100 to achieve the function of filling and sealing.

[0103] It should be noted that the aforementioned sealing element 130 may include not only vacuum foam, but also rubber or silicone, or other sealing materials. This application embodiment does not limit this.

[0104] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support member 110 includes a first surface 1102 facing the battery module 140 and a second surface 1103 facing the injection space 150; the support member 110 has a side surface 1104 connecting the first surface 1102 and the second surface 1103. The first port 11011 of the injection channel 1101 is located on the second surface 1103 and communicates with the injection space 150; the second port 11012 of the injection channel 1101 is located on the side surface 1104.

[0105] In this embodiment, the first port 11011 of the adhesive inlet channel 1101 is located on the second surface 1103 and communicates with the adhesive injection space 150; the second port 11012 of the adhesive inlet channel 1101 is located on the side surface 1104. This facilitates the delivery of liquid adhesive into the adhesive injection space 150 from the outside through the second port 11012 of the adhesive inlet channel 1101. Furthermore, placing the second port 11012 of the adhesive inlet channel 1101 on the side surface 1104 of the support member 110 makes the second port 11012 of the adhesive inlet channel 1101 easier to identify, thereby achieving the effect of automatic adhesive injection, thus improving the adhesive injection efficiency and the production efficiency of the battery pack 100.

[0106] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support member 110 includes an injection pipe 1105, which is disposed on the side 1104 and communicates with the second port 11012 of the glue inlet channel 1101; the opening of the injection pipe 1105 protrudes from the side 1104 where the injection pipe 1105 is located.

[0107] Since the support member 110 includes an injection pipe 1105, which is located on the side 1104 and communicates with the second port 11012 of the glue inlet channel 1101, glue injection can be performed simply by aligning the injection nozzle with the opening of the injection pipe 1105. This makes the glue injection operation more convenient compared to directly aligning the injection nozzle with the second port 11012 of the glue inlet channel 1101.

[0108] Because the opening of the injection tube 1105 protrudes from the side 1104 where the injection tube 1105 is located, the opening of the injection tube 1105 is easier to identify during glue injection, which facilitates automated glue injection.

[0109] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The cross-section of the glue inlet channel 1101 is annular.

[0110] Because a circular channel has a smaller total inner surface area compared to channels with other cross-sectional shapes, for the same length and cross-sectional area, less adhesive adheres to the inner wall of the adhesive injection channel 1101 during injection, thus reducing adhesive waste and lowering the production cost of the battery pack 100.

[0111] It should be noted that the cross-section of the aforementioned glue inlet channel 1101 refers to the cross-section obtained after the glue inlet channel 1101 is cut by a plane perpendicular to its own central axis.

[0112] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The second port 11012 of the glue inlet channel 1101 and the outlet 160 are located on the side 1104 of the same side of the support member 110.

[0113] During the glue injection operation, an external visual inspection device is typically used to identify the position of the second port 11012 of the glue inlet channel 1101, thereby aligning the glue nozzle. Simultaneously, the external visual inspection device also identifies whether glue has overflowed from the outlet 160, thus determining whether the glue injection space 150 is completely filled, thereby automating the start and stop of the glue injection operation. Based on the above, when the second port 11012 of the glue inlet channel 1101 and the outlet 160 are located on the same side 1104 of the support member 110, the glue injection operation can be completed simply by having the external visual inspection device identify one direction of the support member 110, thereby improving the efficiency of glue injection.

[0114] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The second port 11012 of the glue inlet channel 1101 and the outlet 160 are located on the side 1104 of the support 110 facing the cover 1200 of the battery pack 100.

[0115] The cover plate 1200 of the battery pack 100 is placed on the side of the placement cavity 121 of the tray 120 with an opening, and is used to seal the placement cavity 121, which can protect the battery cell module 140 inside the placement cavity 121.

[0116] During the production of the battery pack 100, the cover plate 1200 is typically located above the placement cavity 121. At this time, the second port 11012 of the adhesive inlet channel 1101 and the outlet 160 are located on the side 1104 above the support member 110. Thus, during adhesive injection, the adhesive is injected from top to bottom, while the gas in the adhesive injection space 150 is expelled from bottom to top. Consequently, under the influence of gravity, the adhesive injection space 150 is more easily filled and compacted, thus improving the quality of adhesive injection. Furthermore, when venting gas from bottom to top, it is easier for the gas to escape, thereby improving the efficiency of adhesive injection.

[0117] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The number of exhaust ports 160 is at least two. This increases the venting speed of the glue injection space 150 during glue injection, thereby improving the efficiency of glue injection.

[0118] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 Along the length of the side 1104 where the outlet 160 is located, at least two outlets 160 are provided at intervals.

[0119] In this way, during glue injection, at least two exhaust ports 160 can simultaneously vent air from different parts of the glue injection space 150 along the length of the side 1104. This further increases the venting speed of the glue injection space 150, thereby further improving the glue injection efficiency.

[0120] It should be noted that the length extension direction of the aforementioned side 1104 refers to the direction of the straight line containing the longer side of the side 1104.

[0121] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 Along the length of the side 1104 where the second port 11012 and the outlet 160 are located, at least two outlets 160 are respectively provided on opposite sides of the second port 11012.

[0122] During glue injection, at least two exhaust ports 160 can simultaneously vent air from different locations on opposite sides of the second port 11012 of the glue inlet channel 1101 along the length of the side 1104. This allows the gas in the glue injection space 150 to be evenly discharged from different locations, thereby further increasing the venting speed of the glue injection space 150 and thus further improving the glue injection efficiency.

[0123] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 There are two outlets 160. The second port 11012 is located in the middle of the side 1104 where the second port 11012 and the outlet 160 are located.

[0124] At least one outlet 160 is provided near the end of the side surface 1104. This allows at least one outlet 160 to vent air from the end of the injection space 150 along the length of the side surface 1104 during adhesive injection. This ensures that the gas in the injection space 150 is evenly discharged from the end of the injection space 150, which in turn facilitates a denser filling of the injection space 150, thus improving the quality of adhesive injection.

[0125] Alternatively, two outlets 160 may be positioned near the two ends of the side surface 1104, and equidistant from the second port 11012. Thus, along the length of the side surface 1104, the two outlets 160 are symmetrically positioned relative to the second port 11012 of the glue inlet channel 1101. During glue injection, the two outlets 160 can vent air from the two opposite ends of the glue injection space 150 along the length of the side surface 1104. This allows the gas in the glue injection space 150 to be evenly discharged from the two opposite ends, thereby ensuring a balanced flow rate of adhesive from the center to the two ends of the glue injection space 150. This promotes a denser filling of the glue injection space 150, thus improving the quality of glue injection.

[0126] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4The support member 110 has a limiting groove 1106 on the side facing the glue injection space 150, and the limiting groove 1106 is used to set the seal 130. In this way, the seal 130 and the support member 110 are connected to form a whole. When producing the battery pack 100, it is only necessary to connect the side of the support member 110 with the seal 130 to the tray 120 to form the glue injection space 150. That is, only the combination of two parts is needed to form the glue injection space 150. Compared with the solution of forming the glue injection space 150 by combining three parts, the glue injection efficiency can be improved, thereby improving the production efficiency of the battery pack 100.

[0127] Alternatively, a limiting groove 1106 may be provided on the side of the tray 120 facing the injection space 150, and the limiting groove 1106 is used to set the seal 130. In this way, the seal 130 and the tray 120 are connected to form a whole. When producing the battery pack 100, it is only necessary to connect the support 110 to the side of the tray 120 with the seal 130 to form the injection space 150. That is, only the combination of two parts is needed to form the injection space 150. Compared with the solution of forming the injection space 150 by combining three parts, the injection efficiency can be improved, thereby improving the production efficiency of the battery pack 100.

[0128] It should be noted that the sealing element 130 may be provided on only one of the support member 110 and the tray 120, or the sealing element 130 may be provided on both the support member 110 and the tray 120. This application embodiment does not limit this.

[0129] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The shape of the limiting groove 1106 is adapted to match the shape of the seal 130.

[0130] In this way, the seal 130 can be completely accommodated in the limiting groove 1106, thereby preventing the seal 130 from moving relative to the limiting groove 1106, thus making the structure of the battery pack 100 more stable.

[0131] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting groove 1106 is annular in shape with a notch 11061. The support member 110, the seal member 130 and the tray 120 surround each other at the notch 11061 to form an outlet 160.

[0132] When the seal 130 is housed in the limiting groove 1106, the opening position formed by the sealing section 131 corresponds to the position of the notch 11061 in the limiting groove 1106, and thus the support 110, the seal 130 and the tray 120 can be closed at the notch 11061 to form the discharge port 160.

[0133] The number of notches 11061 in the limiting groove 1106 is the same as the number of openings formed by the sealing section 131, and they correspond one-to-one.

[0134] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support member 110 has a discharge groove 1107 on the side facing the glue injection space 150. The discharge groove 1107 is located at the notch 11061, and the inner wall of the discharge groove 1107, the seal 130 and the tray 120 enclose to form a discharge port 160.

[0135] The discharge groove 1107 extends to the side 1104 where the second port 11012 of the glue inlet channel 1101 is located, so that the inner wall of the discharge groove 1107, the seal 130 and the tray 120 can be enclosed to form the discharge outlet 160.

[0136] The number of discharge grooves 1107 is the same as the number of openings formed by the sealing section 131, and they correspond one-to-one.

[0137] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 A first wire groove 1108 is provided on the side 1104 where the second port 11012 and the outlet 160 are located. The first wire groove 1108 extends along the length of the side 1104 and is used to accommodate the power transmission cable bundle 170.

[0138] When the glue injection assembly 11 is installed in the battery pack 100, the power transmission harness 170 of the battery pack 100 can be accommodated in the first wire groove 1108. This facilitates full utilization of the space of the glue injection assembly 11, thus contributing to the miniaturization design of the battery pack 100.

[0139] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The injection tube 1105 of the glue injection assembly 11 is located in the first wire groove 1108, and the opening of the injection tube 1105 is higher than the height of the wire harness in the first wire groove 1108.

[0140] In this way, when the first wire groove 1108 contains the wire harness, the glue injection nozzle will not come into contact with the wire harness in the first wire groove 1108 during glue injection, thereby preventing the wire harness in the first wire groove 1108 from being damaged, thus improving the production quality of the battery pack 100.

[0141] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support member 110 is provided with a second wire groove 1109, which is spaced apart from the first wire groove 1108 and extends in the same direction; the second wire groove 1109 is used to accommodate the monitoring wire harness 180.

[0142] Specifically, the second wire groove 1109 is disposed between the first wire groove 1108 and the limiting groove 1106. Since the second wire groove 1109 is used to accommodate the monitoring wire harness 180, when the glue injection assembly 11 is installed in the battery pack 100, the monitoring wire harness 180 of the battery pack 100 can be accommodated in the second wire groove 1109. This facilitates full utilization of the space in the glue injection assembly 11, thus contributing to the miniaturization design of the battery pack 100.

[0143] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The support member 110 is provided with a mounting groove 1110, the groove opening of the mounting groove 1110 is located on the second surface 1103, and the bottom of the mounting groove 1110 is provided with a mounting hole 11101, which is used to install the monitoring member 190.

[0144] This facilitates the installation of a monitoring component 190 on the glue-filling assembly 11. This monitoring component 190 is used to monitor the performance data of the battery cell, allowing technicians to monitor the cell's operating status in real time. This performance data includes the cell temperature.

[0145] Because the bottom of the mounting slot 1110 has mounting holes 11101 for mounting the monitoring component 190, the monitoring component 190 can directly contact the surface of the battery cell, thereby enabling more accurate monitoring of the battery cell temperature.

[0146] It should be noted that the aforementioned monitoring harness 180 is connected to the monitoring component 190, and the monitoring harness 180 is used to transmit data from the monitoring component 190.

[0147] The performance data that was monitored.

[0148] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The edge of the mounting hole 11101 is provided with a locking member 11102, which is used to connect with the monitoring member 190.

[0149] It should be noted that the locking component 11102 can be two oppositely arranged buckles, with the two opposite sides of the monitoring component 190 connected to the two buckles respectively. In this way, the locking component 11102 can fix the monitoring component 190, thereby making the monitoring component 190 more securely installed, and thus making the structure of the battery pack 100 more stable. The locking component 11102 can also be a bolt, which connects the monitoring component 190 to the edge of the mounting hole 11101. Furthermore, the locking component 11102 can also be other types of connection structures, which are not limited in this embodiment.

[0150] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The groove of the mounting groove 1110 is located in the middle of the second surface 1103, and the limiting groove 1106 of the support member 110 is at least partially arranged around the outer periphery of the mounting groove 1110.

[0151] Since the temperature in the middle of the cell surface can accurately reflect the true temperature of the cell, when the slot opening of the mounting groove 1110 is located in the middle of the second surface 1103, the monitoring element 190 is also located in the middle of the second surface 1103, thus enabling the monitoring of the temperature in the middle of the cell surface, and therefore accurately reflecting the true temperature of the cell.

[0152] Because the limiting groove 1106 of the support member 110 is at least partially circumferentially arranged around the outer periphery of the mounting groove 1110, the mounting groove 1110 can communicate with the glue injection space 150. Thus, during glue injection, the adhesive can flow into the mounting groove 1110, thereby enabling a tighter connection between the monitoring member 190 and the mounting groove 1110, making the structure of the battery pack 100 more stable.

[0153] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The second surface 1103 is provided with a connecting groove 1111, which connects the second wire groove 1109 and the mounting groove 1110 to accommodate the monitoring wire harness 180 connected to the monitoring component 190.

[0154] In this way, the monitoring harness 180 is embedded in the support member 110, which makes full use of the space of the glue injection assembly 11, thus facilitating the miniaturization design of the battery pack 100.

[0155] This application also provides a battery pack 100, see [link to previous document]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a tray 120, a cell module 140, and any one of the aforementioned glue injection components 11. The tray 120 has a placement cavity 121. The cell module 140 is located within the placement cavity 121. The glue injection component 11 is disposed between the cell module 140 and the tray 120. The support member 110 of the glue injection component 11 and the tray 120 enclose a glue injection space 150 and a discharge port 160. The glue inlet channel 1101 and the discharge port 160 of the support member 110 are both connected to the glue injection space 150.

[0156] Since the battery pack 100 includes a tray 120 and a cell module 140, the tray 120 has a placement cavity 121, and the cell module 140 is disposed within the placement cavity 121. This creates a gap between the cell module 140 and the tray 120, which can accommodate the injection assembly 11. Specifically, the support member 110 of the injection assembly 11 is disposed between the side wall of the cell module 140 and the inner wall of the placement cavity 121.

[0157] Since the glue injection assembly 11 includes a support member 110, which, together with the tray 120, forms a glue injection space 150, this is a significant improvement over the prior art where a vacuum foam strip is attached to the inner wall of the tray 120, the first side 1102 of a PP sheet is attached to the vacuum foam strip, and the second side 1103 of the PP sheet, opposite to the first side 1102, is connected to the side plate, with the PP sheet, vacuum foam strip, and the inner wall of the tray 120 forming the glue injection cavity. This support member 110 replaces the assembly of the side plate and the PP sheet. This simplifies the structure of the battery pack 100, thereby improving its production efficiency and reducing its production cost.

[0158] Because the support member 110 has an adhesive inlet channel 1101 that communicates with the adhesive injection space 150, compared to the prior art where the first side 1102 of the PP sheet is adhered to a vacuum foam strip and the second side 1103 of the PP sheet, which is opposite to the first side 1102, is connected to the side plate, the adhesive inlet channel 1101 is part of the support member 110. Therefore, as long as the position of the support member 110 can be identified, the position of the adhesive inlet channel 1101 can be accurately located. This makes the adhesive inlet channel 1101 easily identifiable during adhesive injection, thus achieving automatic adhesive injection and eliminating the need for manual alignment, thereby further reducing the production cost of the battery pack 100.

[0159] Since the support member 110 and the tray 120 enclose and form an outlet 160, which is connected to the glue injection space 150, the gas in the glue injection space 150 can be smoothly discharged when glue is injected into the glue injection space 150 through the glue inlet channel 1101, thereby increasing the glue injection rate and further improving the production efficiency of the battery pack 100.

[0160] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 also includes an adhesive 1100, which fills the injection space 150.

[0161] In this way, the adhesive 1100 can tightly bond the support 110 to the tray 120. The first surface 1102 of the support 110 is connected to the cell module 140. Thus, the adhesive 1100 tightly bonds the cell module 140 and the tray 120 together, thereby improving the structural stability of the battery pack 100.

[0162] It should be noted that the aforementioned adhesive component 1100 is formed by curing the adhesive that flows into the injection space 150. This adhesive can be a glue or other types of adhesive, and this embodiment does not limit the specific type. When the adhesive is a glue, it can be a structural adhesive or a thermally conductive adhesive.

[0163] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a power transmission cable harness 170, which is housed in a first cable groove 1108 of the support member 110.

[0164] The power transmission harness 170 is used to charge the cells in the battery pack 100 or to output the electrical energy stored in the cells. The power transmission harness 170 of the battery pack 100 can be accommodated in the first wire groove 1108, which helps to make full use of the space of the glue injection assembly 11, thus facilitating the miniaturization design of the battery pack 100.

[0165] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a monitoring harness 180, which is housed in a second wire groove 1109 of the support member 110.

[0166] The monitoring harness 180 is used to transmit performance data monitored by the monitoring component 190. The second wire groove 1109 is disposed between the first wire groove 1108 and the limiting groove 1106. Since the monitoring harness 180 is housed in the second wire groove 1109 of the support component 110, it is beneficial to make full use of the space of the glue injection assembly 11, thus facilitating the miniaturization design of the battery pack 100.

[0167] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a monitoring component 190, which is mounted on a support 110 and connected to a locking component 11102 of the support 110, for collecting cell performance data.

[0168] This allows technicians to monitor the cell's operating status in real time. This performance data includes the cell temperature.

[0169] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The monitoring harness 180 extends along the second wire groove 1109 and the connecting groove 1111 of the support member 110 into the mounting groove 1110 of the support member 110 and is connected to the monitoring member 190.

[0170] In this way, the monitoring harness 180 can transmit the cell performance data monitored by the monitoring device 190. In addition, since the monitoring harness 180 is embedded in the support member 110, the space of the glue injection assembly 11 can be fully utilized, which is beneficial to the miniaturization design of the battery pack 100.

[0171] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The sealing element 130 of the glue injection assembly 11 is housed in the limiting groove 1106 of the support 110.

[0172] In this way, the seal 130 and the support 110 are connected to form a whole. When producing the battery pack 100, it is only necessary to connect the side of the support 110 with the seal 130 to the tray 120 to form the glue injection space 150. That is, only the combination of two parts is needed to form the glue injection space 150. Compared with the solution of forming the glue injection space 150 by combining three parts, the glue injection efficiency can be improved, thereby improving the production efficiency of the battery pack 100.

[0173] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The pallet 120 includes a pallet base plate 122 and a pallet beam 123 connected to each other, which together form a placement cavity 121. The glue injection assembly 11 and the pallet beam 123 together form a glue injection space 150 and a discharge port 160.

[0174] The battery module is housed in the placement cavity 121 and forms a gap with the tray beam 123, which can accommodate the glue injection assembly 11.

[0175] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 and Figure 4 The battery pack 100 includes a cover plate 1200, which covers the opening side of the placement cavity 121. Along the direction from the tray bottom plate 122 to the cover plate 1200, the top surface of the cell module 140 is higher than the opening of the injection tube 1105 of the glue injection assembly 11.

[0176] Since the battery pack 100 includes a cover plate 1200, which covers the opening side of the placement cavity 121, the cover plate 1200 can seal the top of the placement cavity 121, thereby protecting the cell module 140.

[0177] Because the top surface of the battery cell module 140 is higher than the opening of the injection tube 1105 of the glue injection assembly 11 along the direction from the bottom plate 122 to the cover plate 1200, when the glue is injected into the injection space 150 through the opening of the injection tube, the adhesive can be prevented from flowing onto the top surface of the battery cell module 140 and affecting the glue spreading on the top surface of the battery cell module 140.

[0178] It should be noted that the aforementioned tray 120 is provided with a weight-reducing part 124 to reduce the weight of the tray 120, thereby reducing the weight of the battery pack 100. Specifically, the weight-reducing part 124 is provided on the tray beam 123. The weight-reducing part 124 can be a weight-reducing cavity or a weight-reducing hole, or other types of weight-reducing structures, which are not limited in this embodiment.

[0179] This application also provides an electrical device, see [link to relevant documentation] Figure 1 , Figure 2 , Figure 3 and Figure 4 The electrical equipment includes any of the above-mentioned glue injection components 11 or any of the above-mentioned battery packs 100.

[0180] Since the battery pack 100 includes a tray 120 and a cell module 140, the tray 120 has a placement cavity 121, and the cell module 140 is disposed within the placement cavity 121. This creates a gap between the cell module 140 and the tray 120, which can accommodate the injection assembly 11. Specifically, the support member 110 of the injection assembly 11 is disposed between the side wall of the cell module 140 and the inner wall of the placement cavity 121.

[0181] Since the glue injection assembly 11 includes a support member 110, which is adapted to enclose the tray 120 to form a glue injection space 150, compared to the prior art where a vacuum foam strip is attached to the inner wall of the tray 120, the first side 1102 of a PP sheet is attached to the vacuum foam strip, and the second side 1103 of the PP sheet, which is opposite to the first side 1102, is connected to the side plate, and the PP sheet, vacuum foam strip, and inner wall of the tray 120 enclose the glue injection cavity, the support member 110 replaces the assembly of the side plate and the PP sheet. This simplifies the structure of the battery pack 100, thereby improving the production efficiency and reducing the production cost of the battery pack 100, which in turn improves the production efficiency and reduces the production cost of the electrical equipment.

[0182] Because the support member 110 has an adhesive inlet channel 1101 that communicates with the adhesive injection space 150, compared to the prior art where the first side 1102 of the PP sheet is adhered to a vacuum foam strip and the second side 1103 of the PP sheet, which is opposite to the first side 1102, is connected to the side plate, the adhesive inlet channel 1101 is part of the support member 110. Therefore, as long as the position of the support member 110 can be identified, the position of the adhesive inlet channel 1101 can be accurately located. This makes the adhesive inlet channel 1101 easily identifiable during adhesive injection, thus achieving automatic adhesive injection and eliminating the need for manual alignment. This further reduces the production cost of the battery pack 100 and consequently, the production cost of electrical equipment.

[0183] Since the support member 110 is adapted to enclose the tray 120 to form an outlet 160, which communicates with the glue injection space 150, the gas in the glue injection space 150 can be smoothly discharged when glue is injected into the glue injection space 150 through the glue inlet channel 1101, thereby increasing the glue injection rate and further improving the production efficiency of the battery pack 100, which in turn further improves the production efficiency of the electrical equipment.

[0184] It should be noted that the aforementioned electrical equipment may be electric vehicles, electrical appliances, or construction machinery, or other types of electrical equipment; this application embodiment does not limit this.
