[0057] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0058] As described in the background, a battery includes a cell module for storing and releasing electrical energy. This cell module consists of multiple interconnected cells. During battery manufacturing, glue can be locally injected between the cells to allow the glue to fill the gaps between adjacent cells. This allows the glue to connect adjacent cells, further stabilizing the cell module structure.

[0059] When locally injecting glue between multiple battery cells, a waterproof rubber pad can be set at the end of the battery cell to cover the safety valve, connection part and other structures at the end of the battery cell through the waterproof rubber pad, thereby reducing the possibility of contact between the safety valve, connection part and other structures of the battery cell and the colloid, thereby ensuring the normal use of the battery cell.

[0060] Furthermore, to ensure a more stable and accurate glue filling process for the battery cell module, a glue filling mold is required at the ends of the battery cell. This mold provides a certain degree of positioning and guidance, reducing the possibility of the glue flowing to the ends of the battery cell. However, the process of localized glue filling between multiple battery cells is cumbersome and results in poor battery stability.

[0061] In order to solve the above technical problems, the embodiment of the present application provides a battery module, a battery and an electrical device. The battery bracket includes a first bracket, the first bracket is provided with a glue tank, and a plurality of plug-in slots are provided in the glue tank. The battery cell can be plugged into the plug-in slot. After the glue tank is filled with colloid, the battery cell can be fixedly connected to the plug-in slot and the glue tank, so that the installation of multiple battery cells is more stable.

[0062] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0063] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0064] Reference Figure 1-Figure 3 The embodiment of the present application provides a cell holder 200 suitable for a cell module 10. The cell holder 200 can be used to support and fix multiple cells 100 to make the structure of the multiple cells 100 more stable and reduce the possibility of the cells 100 in the cell module 10 falling off.

[0065] The structure of the battery cell 100 supported and fixed by the battery cell holder 200 in the battery cell module 10 will be described below.

[0066] In some possible implementations, the multiple battery cells 100 in the battery cell module 10 may be connected in series in sequence to increase the output voltage of the battery cell module 10 .

[0067] For example, the battery cell 100 may be configured as a cylindrical battery cell 100 , which is cylindrical in shape as a whole.

[0068] The multiple battery cells 100 can be arranged in multiple rows and columns, with gaps formed between adjacent battery cells 100. For example, the battery cells 100 are arranged as cylindrical battery cells 100, and the outer surfaces of two adjacent cylindrical battery cells 100 can be tangent to each other. The outer surfaces of four cylindrical battery cells 100 arranged in a square are tangent to each other in sequence, and the middle of the four cylindrical battery cells 100 is tangent to each other.

[0069] The cylindrical battery cell 100 includes two ends spaced apart from each other along its axis. A connector 120 may be provided at one end of the battery cell 100. The connector 120 may include at least one of a positive electrode connector and a negative electrode connector, so that the battery cells 100 can be connected in series via the connector 120.

[0070] A safety valve 110 may be provided at the other end of the battery cell 100. The safety valve 110 can open when a fault occurs in the battery cell 100, thereby reducing the possibility of combustion or explosion of the battery cell 100.

[0071] It should be noted that the battery cell 100 may include a positive electrode connecting portion and a negative electrode connecting portion, and the battery cell 100 may be electrically connected to other battery cells 100 or electrical devices through the positive electrode connecting portion and the negative electrode connecting portion.

[0072] The positive and negative electrode connectors are disposed on the same side and can be located at the same end of the battery cell 100. The positive and negative electrode connectors can be disposed on opposite sides of the safety valve 110, that is, the positive and negative electrode connectors can be disposed at the end of the battery cell 100 where the safety valve 110 is not disposed. The positive and negative electrode connectors constitute the connector 120.

[0073] Alternatively, the positive electrode connection portion and the negative electrode connection portion may be provided on different sides. The positive electrode connection portion may be provided at one end of the battery cell 100 , and the negative electrode connection portion may be provided at the other end of the battery cell 100 .

[0074] One of the positive electrode connection part and the negative electrode connection part can be set on the same side as the safety valve 110, and the other of the positive electrode connection part and the negative electrode connection part can be set on the opposite side of the safety valve 110. The positive electrode connection part or the negative electrode connection part set on the opposite side of the safety valve 110 is the connection part 120.

[0075] In some possible implementations, the battery cell holder 200 may include a first holder 210 and a second holder 220 connected to each other, so that the battery cell 100 is fixed by the first holder 210 and the second holder 220 .

[0076] Illustratively, the first bracket 210 secures the first ends of the plurality of battery cells 100. The first bracket 210 is provided with a glue groove 211 that accommodates at least a portion of the battery cells 100. The second bracket 220 secures the opposite second ends of the plurality of battery cells 100, thereby securing the battery cells 100 at both ends along the axial direction through the mating first bracket 210 and second bracket 220.

[0077] It is easy to understand that in the process of locally pouring glue between multiple battery cells 100, the glue pouring head used for pouring glue can be directed toward the second bracket 220, so that glue can be poured between the multiple battery cells 100 through the second bracket 220, so that the glue can flow from between the multiple battery cells 100 to the glue tank 211 of the first bracket 210 to realize the glue pouring process of the battery cell module 10.

[0078] After the glue is filled into the glue tank 211 , the glue can solidify in the glue tank 211 to easily form a glue layer, and the glue layer can be filled between adjacent battery cells 100 , so that the glue layer can fix multiple battery cells 100 and the first bracket 210 , thereby making the structure of the battery cell module 10 more stable.

[0079] Exemplarily, the glue layer is arranged in the glue groove 211 of the first bracket 210, so that the glue layer does not need to be completely filled between the multiple battery cells 100, so as to reduce the amount of glue used, thereby reducing the cost of the glue filling process of the battery cell module 10 and reducing the time of the glue filling process of the battery cell module 10.

[0080] Reference Figure 3-Figure 5In some possible embodiments, the first bracket 210 may be provided with a plurality of plug-in slots 212, which may be used for inserting the battery cells 100, thereby enabling the plug-in slots 212 to play a certain positioning and guiding role in the insertion process of the battery cells 100, making the process of the first bracket 210 supporting and fixing the battery cells 100 more convenient.

[0081] The plurality of insertion slots 212 are provided corresponding to the plurality of battery cells 100 , so that the battery cells 100 are inserted into the corresponding insertion slots 212 , thereby fixing the corresponding battery cells 100 through the insertion slots 212 and reducing the possibility of the battery cells 100 shaking.

[0082] The insertion slot 212 can be connected to the glue tank 211. When the battery cell 100 is inserted into the insertion slot 212, at least part of the battery cell 100 can be located outside the insertion slot 212 and inside the glue tank 211, so that the battery cell 100 can contact the glue.

[0083] When the battery cell 100 is not inserted into the insertion slot 212 , the insertion slot 212 can be communicated with the glue storage slot 211 .

[0084] For example, when the battery cell 100 is inserted into the insertion slot 212 , the battery cell 100 can seal the insertion slot 212 , so that the glue in the glue holding slot 211 does not flow into the insertion slot 212 .

[0085] Alternatively, for example, when the battery cell 100 is inserted into the insertion slot 212 , the battery cell 100 may partially close the insertion slot 212 , allowing the colloid in the glue holding slot 211 to flow into the insertion slot 212 , thereby increasing the contact area between the colloid and the battery cell 100 .

[0086] Exemplarily, the shape of the insertion slot 212 can be adjusted according to the shape of the battery cell 100. For example, when the shape of the battery cell 100 is set to be cylindrical, the insertion slot 212 can be set to be a circular insertion slot 212 so that the battery cell 100 can be more stably inserted into the insertion slot 212.

[0087] When the battery cell 100 is inserted into the corresponding insertion slot 212 , the insertion slot 212 may be transitionally fitted with the battery cell 100 , or the insertion slot 212 may be interference fit with the battery cell 100 , so that the connection between the battery cell 100 and the insertion slot 212 is more stable.

[0088] Furthermore, when glue is poured between the multiple battery cells 100, the glue can flow from between the multiple battery cells 100 into the glue reservoir 211. Considering the fluidity of the glue, by providing a transition fit or interference fit between the insertion groove 212 and the battery cell 100, the possibility of the glue flowing from the glue reservoir 211 into the insertion groove 212 can be reduced, thereby reducing the possibility of the glue contacting the end surface of the battery cell 100.

[0089] Reference Figure 3-Figure 5 In some possible implementations, a connection port 213 may be provided on the bottom wall of the insertion slot 212 .

[0090] When the battery cell 100 is not inserted into the insertion slot 212, the connection port 213 can be connected to the glue groove 211, so that the first end of the battery cell 100 can move toward the connection port 213 of the insertion slot 212 through the glue groove 211, and at least part of the end face of the first end of the battery cell 100 can be exposed through the connection port 213.

[0091] When the battery cell 100 is inserted into the insertion slot 212, the first end of the battery cell 100 can close the connection port 213 so that the connection port 213 is not connected to the glue tank 211, so that the glue will not flow from the glue tank 211 to the connection port 213, reducing the possibility of the glue contacting the end face of the first end of the battery cell 100.

[0092] It is easy to understand that when the battery cell 100 is inserted into the insertion slot 212, the insertion slot 212 and the battery cell 100 are configured to have a transition fit or interference fit, so that the connection port 213 is not connected to the glue tank 211. Alternatively, the first end of the battery cell 100 closes the connection port 213, so that the connection port 213 is not connected to the glue tank 211.

[0093] For example, a connection portion 120 may be provided on an end surface of a first end of the battery cell 100 , and a safety valve 110 may be provided on an end surface of a second end of the battery cell 100 .

[0094] The number of the connection parts 120 can be set to two, and the two connection parts 120 can include a positive connection part and a negative connection part. The positive connection part and the negative connection part can be arranged on the same side of the end surface of the first end of the battery cell 100.

[0095] The number of the connection port 213 can be set to one, and the connection port 213 can be set corresponding to the positive electrode connection part and the negative electrode connection part, and the positive electrode connection part and the negative electrode connection part can be set inside the connection port.

[0096] Alternatively, the number of the connection ports 213 may be two, one of the two connection ports 213 may be provided corresponding to the positive electrode connection portion, and the other of the two connection ports 213 may be provided corresponding to the negative electrode connection portion.

[0097] When the battery cell 100 is inserted into the insertion slot 212, the connecting portion 120 located at the first end of the battery cell 100 can be set in the connecting port 213, so that the connecting portion 120 can be connected to the outside of the first bracket 210 through the connecting port 213, so that the connecting portions 120 of multiple battery cells 100 can be electrically connected through the connecting port 213.

[0098] Furthermore, the connection port 213 is not connected to the glue holding groove 211, so that the glue will not flow to the outside of the first bracket 210 through the connection port 213, thereby reducing the possibility of the glue contacting the connecting piece 240, thereby reducing the influence of the glue on the electrical connection between the connecting piece 240 and the connecting parts 120 of the multiple battery cells 100, and improving the stability of the electrical connection between the connecting piece 240 and the connecting parts 120 of the multiple battery cells 100.

[0099] It should be noted that the battery cells 100 can be inserted into the insertion slots 212 , and the insertion slots 212 can play a certain role in limiting and fixing the multiple battery cells 100 , so that the arrangement between adjacent battery cells 100 is more stable.

[0100] When glue is poured between the multiple battery cells 100 through the glue pouring head, the glue pouring head can be more easily inserted between the multiple battery cells 100, and the first bracket 210 can act as a glue pouring mold for the multiple battery cells 100, thereby reducing the possibility of the glue pouring head facing the end face of the battery cell 100 and improving the glue pouring effect of the battery cell module 10.

[0101] Reference Figure 3 ,as well as Figure 6 and Figure 7 In some possible embodiments, the second bracket 220 may be provided with a glue filling port 222, which is connected to the glue tank 211, so that glue can be poured between the multiple battery cells 100 through the glue filling port 222 of the second bracket 220. The glue filling port 222 located on the second bracket 220 can position and guide the glue filling head, making it easier to insert the glue filling head between the multiple battery cells 100.

[0102] When glue is poured between the multiple battery cells 100 through the glue pouring head, the glue can flow between the multiple battery cells 100 through the glue pouring port 222 , so that the glue can flow into the glue receiving tank 211 .

[0103] For example, the second bracket 220 may include a plurality of mounting slots 221. The plurality of mounting slots 221 may correspond to the plurality of battery cells 100. The mounting slots 221 accommodate corresponding battery cells 100, thereby making the connection between the battery cells 100 and the second bracket 220 more stable.

[0104] The mounting groove 221 may be configured as a through groove, and the mounting groove 221 passes through the second bracket 220. Alternatively, the mounting groove 221 may be configured as a blind groove, and the mounting groove 221 may not pass through the second bracket 220.

[0105] It is easy to understand that when the first end of the battery cell 100 is inserted into the corresponding insertion slot 212, the opposite second end of the battery cell 100 is away from the first bracket 210, and the first bracket 210 can play a certain pre-fixing role for the multiple battery cells 100. Then the second bracket 220 can be connected to the opposite second ends of the multiple battery cells 100, so that the opposite second ends of the multiple battery cells 100 can be inserted into the installation slot 221, so that the opposite second ends of the multiple battery cells 100 can be fixed by the second bracket 220.

[0106] Then, glue can be poured between the multiple battery cells 100 through the glue filling port 222 of the second bracket 220. The glue filling port 222 is connected to the glue tank 211, so that the glue can flow between the multiple battery cells 100 to the glue tank 211 of the first bracket 210, thereby realizing the glue filling process in the battery cell module 10.

[0107] In some possible embodiments, the glue filling port 222 can be located between adjacent mounting grooves 221 , and the glue filling port 222 is used to face between multiple battery cells 100 so that the colloid can flow from the glue filling port 222 toward between multiple battery cells 100 , so that the colloid can be filled between multiple battery cells 100 .

[0108] Illustratively, the multiple battery cells 100 are arranged in multiple rows and columns, and the multiple mounting grooves 221 may be arranged in multiple rows and columns, so that the multiple battery cells 100 can be fixed through the multiple mounting grooves 221 .

[0109] Reference Figure 3 ,as well as Figure 6-Figure 8 In some possible embodiments, the mounting groove 221 is used for inserting the corresponding battery cell 100, and the safety valve 110 located at the second end of the battery cell 100 can be located in the mounting groove 221 to reduce the possibility of contact between the glue filling head and the safety valve 110, thereby reducing the possibility of the safety valve 110 being contaminated by the colloid, and reducing the possibility of the safety valve 110 being blocked by the colloid and causing safety hazards.

[0110] For example, when the opposite second end of the battery cell 100 is inserted into the mounting groove 221, the safety valve 110 located on the end face of the second end of the battery cell 100 can be located in the mounting groove 221, and the safety valve 110 can pass through the mounting groove 221 toward the outside of the second bracket 220, so that the safety valve 110 can be separated from the main part of the battery cell 100 by the second bracket 220 to reduce the possibility of colloidal contact between the safety valve 110 and multiple battery cells 100.

[0111] Moreover, when glue is locally injected between the multiple battery cells 100 through the glue injection port 222 of the second bracket 220, the second bracket 220 can be reused to form a glue injection mold, thereby eliminating the need to set a waterproof rubber pad on the safety valve 110, making the process of locally injecting glue between the multiple battery cells 100 more convenient and improving the battery preparation efficiency.

[0112] The second bracket 220 may be provided with a frame 223, with the glue injection port 222 and the mounting slot 221 both located inside the frame 223. The frame 223 can provide support and protection for the second bracket 220, thereby reducing the possibility of the second bracket 220 being squeezed and deformed, and thus reducing the possibility of damage to the battery cell 100.

[0113] The frame 223 can be integrated with the second bracket 220 to make the connection between the frame 223 and the second bracket 220 more stable, reduce the deformation of the frame 223 caused by impact, and reduce the possibility of deformation of the battery cell 100 located in the installation groove 221 of the second bracket 220.

[0114] Illustratively, the second bracket 220 is provided with a support member 224 , and the support member 224 is located on a side of the second bracket 220 away from the first bracket 210 .

[0115] When connecting multiple battery cells 100 to the first bracket 210, the second bracket 220 connecting the multiple battery cells 100 can be placed on the workbench through the support member 224, so that the first ends of the multiple battery cells 100 are located above the second ends of the battery cells 100, so that the opposite second ends of the battery cells 100 can be connected to the second bracket 220 to realize the connection between the battery cells 100 and the second bracket 200.

[0116] Reference Figure 2 and Figure 3 In some possible implementations, the battery cell holder 200 may further include a connection structure 230 , and the first holder 210 and the second holder 220 may be fixed via the connection structure 230 .

[0117] For example, the first bracket 210 and the second bracket 220 may be spaced apart. The space between the first bracket 210 and the second bracket 220 may be used to observe the height of the glue in the glue tank 211 , thereby making it easier to control the glue filling amount between the multiple battery cells 100 .

[0118] When the first bracket 210 and the second bracket 220 are fixed by the connecting structure 230, the height of the multiple battery cells 100 and the glue in the glue tank 211 can be observed through the gap between the first bracket 210 and the second bracket 220, so that the glue filling amount between the multiple battery cells 100 can be more accurately controlled on the basis of ensuring the connection stability between the multiple battery cells 100, thereby reducing the cost of the glue filling process.

[0119] It is easy to understand that the connecting structure 230 can be arranged on the side of the first bracket 210 facing the second bracket 220, and the end of the connecting structure 230 facing away from the first bracket 210 can be detachably connected to the second bracket 220 so that the first bracket 210 can be fixed to the second bracket 220 through the connecting structure 230.

[0120] Alternatively, the connecting structure 230 can be arranged on the side of the second bracket 220 facing the first bracket 210, and the end of the connecting structure 230 facing away from the second bracket 220 can be detachably connected to the first bracket 210, so that the second bracket 220 can be fixed to the first bracket 210 through the connecting structure 230.

[0121] For example, the length of the connecting structure 230 is adjustable.

[0122] When the first bracket 210 and the second bracket 220 are suitable for fixing battery cells 100 of different specifications, the distance between the first bracket 210 and the second bracket 220 changes. By setting the connecting structure 230 to be adjustable in length, the length of the connecting structure 230 can be adjusted according to the length of the battery cell 100, so that the distance between the first bracket 210 and the second bracket 220 changes. The first bracket 210 and the second bracket 220 can be used to fix battery cells 100 of different lengths.

[0123] In some possible implementations, the connection structure 230 may include a first connection member 231 and a second connection member 232 that match each other.

[0124] Among them, the first connecting member 231 is arranged on the side of the first bracket 210 facing the second bracket 220, and the second connecting member 232 is arranged on the side of the second bracket 220 facing the first bracket 210. The first connecting member 231 and the second connecting member 232 are connected, so that the first bracket 210 and the second bracket 220 can be connected through the matching first connecting member 231 and the second connecting member 232.

[0125] The first connector 231 and the second connector 232 are detachably connected to facilitate the connection process of the first bracket 210 and the second bracket 220. For example, the first bracket 210 and the second bracket 220 can be connected to the battery cell 100, and then the first connector 231 and the second connector 232 are fixed to complete the connection process of the first bracket 210, the second bracket 220 and the plurality of battery cells 100.

[0126] Illustratively, the connection structure 230 includes a fixing member 233 , and the first connecting member 231 and the second connecting member 232 can be connected via the fixing member 233 , so that the first bracket 210 and the second bracket 220 are relatively fixed.

[0127] Reference Figure 2 and Figure 3 In some possible implementations, the second connecting member 232 may be provided with an extension opening 2321 , a first end of the extension opening 2321 being provided on the same side as the glue filling opening 222 , and a second end opposite to the extension opening 2321 facing the first connecting member 231 .

[0128] The fixing member 233 can be configured as a fixing screw member. The fixing member 233 is provided in the first connecting member 231 through the extension opening 2321 and is threadedly connected to the first connecting member 231, so that the first connecting member 231 and the second connecting member 232 can be fixed by the fixing member 233.

[0129] The extension opening 2321 can be used for inserting a tool to rotate the fixing member 233 by the tool, so that the fixing member 233 can be threadedly connected to the first connecting member 231, making the rotation process of the fixing member 233 more convenient.

[0130] In addition, the first end of the extension port 2321 is arranged on the same side as the glue filling port 222. After the first connecting member 231 and the second connecting member 232 are connected and fixed by the fixing member 233, glue can be directly poured toward the glue filling port 222 through the glue filling head, thereby eliminating the need to flip the battery cell holder 200, making the glue filling process of the battery cell module 10 more convenient.

[0131] The number of the connecting structures 230 can be set to multiple, and the multiple connecting structures 230 can be arranged at intervals so that the first bracket 210 and the second bracket 220 can be connected and fixed through the multiple connecting structures 230, making the connection between the first bracket 210 and the second bracket 220 more stable.

[0132] Part of the connection structure 230 can be set outside the multiple battery cells 100. For example, the second connector 232 can be set on the frame 223 to make the edge of the battery holder 200 more stable. Part of the connection structure 230 can be set between the multiple battery cells 100 to make the middle of the battery holder 200 more stable.

[0133] In summary, the cell holder 200 includes a first holder 210 and a second holder 220. The first holder 210 secures a first end of the cell 100, and the second holder 220 secures an opposite second end of the cell 100. This allows the cell holder 200 to secure both ends of the cell 100, making the installation of multiple cells 100 more stable.

[0134] The cell holder 200 includes a first holder 210 and a second holder 220. The first holder 210 secures the first end of the cell 100, and the second holder 220 secures the second end of the cell 100. This allows the cell holder 200 to secure both ends of the cell 100, making the installation of multiple cells 100 more stable.

[0135] Moreover, in the process of pouring glue between the multiple battery cells 100, the glue pouring head for pouring glue can be directed toward the second bracket 220, so that glue can be poured between the multiple battery cells 100, so that the glue can flow from the second bracket 220 to the glue tank 211 of the first bracket 210, and the glue can flow between the multiple battery cells 100 to realize the glue pouring process of the battery cell module 10.

[0136] The cell holder 200 of the embodiment of the present application supports and secures multiple battery cells 100 via the second bracket 220, thereby providing a certain positioning and guiding function during the glue pouring process. This makes the glue pouring process of the battery module 10 more stable and accurate, and reduces the possibility of contact between the glue and the end faces of the battery cells 100. Furthermore, compared to the glue pouring process of related technologies, the embodiment of the present application does not require the use of a separate waterproof glue pad and glue pouring mold during the glue pouring process, making the glue pouring process between multiple battery cells 100 more convenient and improving battery production efficiency.

[0137] The embodiment of the present application provides a battery cell module 10 , including a plurality of battery cells 100 , a connecting piece 240 , and the battery cell bracket 200 .

[0139] Illustratively, the connecting piece 240 is disposed on the first bracket 210 , and the connecting piece 240 is used to electrically connect the connecting portions 120 of the plurality of battery cells 100 .

[0140] When multiple battery cells 100 are inserted into the insertion slot 212, the connecting portion 120 located at the first end of the battery cell 100 can be connected to the outside of the first bracket 210 through the connecting port 213. The connecting piece 240 arranged on the first bracket 210 can connect the connecting portions 120 of the multiple battery cells 100 in series in sequence, thereby realizing electrical connection of the multiple battery cells 100.

[0141] In some possible implementations, the battery cell 100 is configured as a cylindrical battery cell 100 .

[0142] The multiple battery cells 100 are arranged in multiple rows and columns.
