[0003] Battery modules typically incorporate heating films to raise the overall temperature of the module, ensuring proper operation in cold weather. These heating films are usually attached to the battery module using adhesive, and pressure is applied after attachment to ensure a secure bond. Therefore, effectively applying pressure to the heating films in battery modules is a pressing issue that needs to be addressed. Utility Model Content

Detailed Implementation

[0041] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0042] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0044] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this application, the term "and / or" indicates that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0047] In the description of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 80° to 90°, the two directions can be considered perpendicular; if the angle between two directions is 0° to 10°, the two directions can be considered parallel.

[0048] like Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of this application provides a pressurizing device 100, which relates to the field of battery technology. It is mainly used to position a battery module 200 and pressurize the heating film 210 of the positioned battery module 200.

[0049] Combination Figures 3 to 5 As shown, the pressurizing device 100 provided in this embodiment has a first direction X, a second direction Y and a third direction Z that are perpendicular to each other, and includes a positioning mechanism 110 and a pressurizing mechanism 120.

[0050] The positioning mechanism 110 includes a first positioning component 1101 and a second positioning component 1102 arranged opposite to each other along the second direction Y. The pressurizing mechanism 120 includes a fixing component 123, a moving component 124, a first pressurizing component 1201 and a second pressurizing component 1202. The fixing component 123 and the positioning mechanism 110 are spaced apart along the third direction Z. The moving component 124 is located between the fixing component 123 and the positioning mechanism 110 along the third direction Z and is slidably connected to the fixing component 123. The first pressurizing component 1201 and the second pressurizing component 1202 are arranged opposite to each other on the moving component 124 along the first direction X.

[0051] When the battery module 200 to be pressurized is located between the first positioning component 1101 and the second positioning component 1102, the first positioning component 1101 and the second positioning component 1102 press against the battery module 200 along the second direction Y, the moving component 124 moves to a preset position along the direction close to the positioning mechanism 110 in the third direction Z, and the first pressurizing component 1201 and the second pressurizing component 1202 press against the battery module 200 along the first direction X.

[0052] For example, a sliding connection between the moving component 124 and the fixed component 123 can be achieved by a combination of linear bearings and guide shafts, or by a combination of sliders and guide rails. For instance, the guide shaft is connected to the moving component 124, and the linear bearing is connected to the fixed component 123 and fitted onto the guide shaft, thereby achieving a sliding connection between the moving component 124 and the fixed component 123 along the third direction Z.

[0053] It is understood that when using the pressurizing device 100 provided in this embodiment, the battery module 200 to be pressurized is located between the first positioning component 1101 and the second positioning component 1102. The first positioning component 1101 and the second positioning component 1102 press against the battery module 200 along the second direction Y, thereby pressing the two opposite sides of the battery module 200 along the second direction Y to achieve positioning of the battery module 200 and improve the positional accuracy of the battery module 200. On this basis, the moving component 124 moves to a preset position along the direction close to the positioning mechanism 110 in the third direction Z. The first pressurizing component 1201 and the second pressurizing component 1202 press against the battery module 200 along the first direction X, thereby pressing the two opposite sides of the battery module 200 along the first direction X to achieve pressurization of the heating film 210 on the two opposite sides of the battery module 200 along the first direction X, so that the heating film 210 can be firmly attached to the battery module 200.

[0054] like Figure 1 As shown, it should be noted that the operation of positioning the battery module 200 between the first positioning component 1101 and the second positioning component 1102 can be accomplished by the conveying device 300. Specifically, the conveying device 300 conveys the tray containing the battery module 200 along the first direction X until the tray and the battery module 200 move to the position of the pressurizing device 100. At this time, the lifting mechanism on the conveying device 300 drives the tray and the battery module 200 to move along the third direction Z in the direction close to the fixing component 123, thereby positioning the battery module 200 between the first positioning component 1101 and the second positioning component 1102.

[0055] like Figure 4 As shown, in one embodiment, the first positioning component 1101 includes a first positioning element 111 and a first driving element 113 connected together, and the second positioning component 1102 includes a second positioning element 112 and a second driving element 114 connected together. The first positioning element 111 and the second positioning element 112 are disposed opposite to each other along the second direction Y. The first driving element 113 is used to drive the first positioning element 111 to move along the second direction Y, and the second driving element 114 is used to drive the second positioning element 112 to move along the second direction Y.

[0056] It should be noted that the drive components mentioned above and below can be electric cylinders, connected motors and ball screws, pneumatic cylinders, linear motor modules, etc. No specific restrictions are placed on the type of each drive component here.

[0057] Understandably, when the battery module 200 to be pressurized is located between the first positioning component 1101 and the second positioning component 1102, the first driving component 113 drives the first positioning component 111 to move in the second direction Y along the direction close to the second positioning component 112. At the same time, the second driving component 114 drives the second positioning component 112 to move in the second direction Y along the direction close to the first positioning component 111, until the first positioning component 111 and the second positioning component 112 press against the two opposite sides of the battery module 200 in the second direction Y, thus completing the positioning of the battery module 200.

[0058] like Figure 7 As shown, further, the first positioning member 111 includes a first inelastic positioning plate 1111 and a first elastic positioning plate 1112, the first inelastic positioning plate 1111 being connected between the first driving member 113 and the first elastic positioning plate 1112, and the thickness of the first elastic positioning plate 1112 being less than the thickness of the first inelastic positioning plate 1111; and / or the second positioning member 112 includes a second inelastic positioning plate 1121 and a second elastic positioning plate 1122, the second inelastic positioning plate 1121 being connected between the second driving member 114 and the second elastic positioning plate 1122, and the thickness of the second elastic positioning plate 1122 being less than the thickness of the second inelastic positioning plate 1121.

[0059] For example, non-elastic positioning plates can be made of metal plates, rigid plastic plates, etc., while elastic positioning plates can be made of silicone plates, rubber plates, etc., without specific limitations.

[0060] It is understandable that by combining the first inelastic positioning plate 1111 and the second elastic positioning plate 1122, and controlling the thickness of the first elastic positioning plate 1112 to be less than the thickness of the first inelastic positioning plate 1111, the first positioning member 111 can stably adhere to the battery module 200 to achieve positioning of the battery module 200, and the possibility of the first positioning member 111 damaging the battery module 200 can be reduced. Similarly, by combining the second inelastic positioning plate 1121 and the second elastic positioning plate 1122, and controlling the thickness of the second elastic positioning plate 1122 to be less than the thickness of the second inelastic positioning plate 1121, the second positioning member 112 can stably adhere to the battery module 200 to achieve positioning of the battery module 200, and the possibility of the second positioning member 112 damaging the battery module 200 can be reduced.

[0061] like Figure 4 and Figure 5As shown, in one embodiment, the fixed component 123 is provided with a third driving member 1251 connected to the moving component 124. The third driving member 1251 is used to drive the moving component 124 to move along a third direction Z.

[0062] It is understandable that after the pressurizing device 100 positions the battery module 200 through the positioning mechanism 110, the third driving member 1251 drives the moving component 124 to move to a preset position in the third direction Z along the direction close to the positioning mechanism 110, so that the pressurizing mechanism 120 can pressurize the heating film 210 on the battery module 200.

[0063] Of course, in the above embodiments, the third driving component 1251 can be omitted, and the moving component 124 can be moved relative to the fixed component 123 along the third direction Z by manual operation.

[0064] like Figure 5 As shown, in one embodiment, the first pressurizing assembly 1201 includes a first pressurizing member 121 and a fourth driving member 1252 connected to each other, and the second pressurizing assembly 1202 includes a second pressurizing member 122 and a fifth driving member 1253 connected to each other. The first pressurizing member 121 and the second pressurizing member 122 are disposed opposite to each other along a first direction X. The fourth driving member 1252 is used to drive the first pressurizing member 121 to move along the first direction X, and the fifth driving member 1253 is used to drive the second pressurizing member 122 to move along the first direction X.

[0065] Understandably, after the moving component 124 moves to a preset position in the third direction Z along the direction close to the positioning mechanism 110, the fourth driving component 1252 drives the first pressing component 121 to move in the first direction X along the direction close to the second pressing component 122 until the first pressing component 121 presses against one side of the battery module 200 along the first direction X, thereby pressurizing the heating film 210 on that side. The fifth driving component 1253 drives the second pressing component 122 to move in the first direction X along the direction close to the first pressing component 121 until the second pressing component 122 presses against the other side of the battery module 200 along the first direction X, thereby pressurizing the heating film 210 on that side.

[0066] like Figure 2 and Figure 6 As shown, the pressurizing mechanism 120 further includes a blocking member 1254 and a sixth driving member 1255 disposed on the moving component 124. The sixth driving member 1255 is connected to the blocking member 1254 and is used to drive the blocking member 1254 to move along a third direction Z. The blocking member 1254 is used to abut against the first pressurizing member 121 to restrict the first pressurizing member 121 from moving in the first direction X away from the second pressurizing member 122.

[0067] It is understandable that when the first pressurizing member 121 presses the heating film 210 on one side of the battery module 200 along the first direction X, the sixth driving member 1255 drives the blocking member 1254 to move along the third direction Z in a direction close to the first pressurizing member 121 until the blocking member 1254 abuts against the first pressurizing member 121, thereby restricting the first pressurizing member 121 from moving away from the second pressurizing member 122 in the first direction X, thus blocking the first pressurizing member 121 and reducing the possibility that the first pressurizing member 121 will detach from the heating film 210 due to the failure of the fourth driving member 1252. Furthermore, the second pressurizing member 122 can better press the heating film 210 on the other side of the battery module 200, improving the effect of pressurizing the heating film 210 of the battery module 200.

[0068] like Figure 8 As shown, further, the movable component 124 is provided with a limiting groove 1241 for receiving at least a portion of the blocking member 1254.

[0069] It is understandable that the setting of the limiting groove 1241 has the effect of limiting the blocking member 1254, increasing the stability of the blocking member 1254, and enabling it to better restrict the first pressure member 121 from detaching from the heating film 210.

[0070] Furthermore, the blocking member 1254 is integrally molded from an elastic material, and the blocking member 1254 is used to contact the surface of the first pressure member 121.

[0071] For example, the elastic material can be silicone, rubber, wood, etc., without specific limitations.

[0072] Understandably, the blocking member 1254, made of an elastic material in one piece, makes flexible contact with the first pressure member 121. Compared to rigid contact, flexible contact can effectively reduce the risk of damage to the components. At the same time, the blocking member 1254 and the first pressure member 121 make surface contact. Compared to point contact and line contact, surface contact has higher stability, thus better preventing the first pressure member 121 from detaching from the heating film 210.

[0073] like Figure 5 and Figure 9As shown, the pressurizing mechanism 120 further includes a first buffer 1256 and a second buffer 1257. The first buffer 1256 and the second buffer 1257 are respectively connected to the moving assembly 124. The first buffer 1256 is located between the first pressurizing member 121 and the second pressurizing member 122 along the first direction X. The second buffer 1257 is located between the second pressurizing member 122 and the first buffer 1256 along the first direction X. The first buffer 1256 is used to abut against the first pressurizing member 121, and the second buffer 1257 is used to abut against the second pressurizing member 122.

[0074] For example, the buffer can be a hydraulic damper, a buffer spring, a sponge block, or other components with a buffering function, without any specific limitations.

[0075] It is understandable that the first buffer 1256 and the second buffer 1257 can buffer the first pressurizing member 121 and the second pressurizing member 122, so that the first pressurizing member 121 and the second pressurizing member 122 can slowly press the battery module 200, thereby reducing the risk of damage to the battery module 200 caused by collision with the first pressurizing member 121 and the second pressurizing member 122.

[0076] like Figure 9 As shown, the pressurizing mechanism 120 further includes a first limiting member 1258 and a second limiting member 1259. The first limiting member 1258 and the second limiting member 1259 are respectively connected to the moving assembly 124. The first limiting member 1258 is used to abut against the first pressurizing member 121 to limit the distance that the first pressurizing member 121 moves in the first direction X along the direction close to the second pressurizing member 122. The second limiting member 1259 is used to abut against the second pressurizing member 122 to limit the distance that the second pressurizing member 122 moves in the first direction X along the direction close to the first pressurizing member 121.

[0077] It is understandable that the first limiting member 1258 can limit the distance that the first pressing member 121 can move in the first direction X along the direction close to the second pressing member 122, and the second limiting member 1259 can limit the distance that the second pressing member 122 can move in the first direction X along the direction close to the first pressing member 121, thereby reducing the possibility that the first pressing member 121 and the second pressing member 122 may cause poor adhesion of the heating film 210 due to excessive pressing of the battery module 200.

[0078] Furthermore, the first limiting member 1258 is a first adjusting bolt, which is threadedly connected to the moving component 124, and the second limiting member 1259 is a second adjusting bolt, which is threadedly connected to the moving component 124.

[0079] It is understandable that by turning the first adjusting bolt, the distance by which the first pressurizing member 121 moves in the first direction X along the direction close to the second pressurizing member 122 can be adjusted, and by turning the second adjusting bolt, the distance by which the second pressurizing member 122 moves in the first direction X along the direction close to the first pressurizing member 121 can be adjusted, so that the pressurizing device 100 can adapt to battery modules 200 of different sizes and specifications.

[0080] Of course, in the above embodiments, the first limiting member 1258 and the second limiting member 1259 can also be elastic limiting blocks. The elastic limiting blocks can also play a limiting role on the first pressing member 121 and the second pressing member 122. Here, no specific restrictions are placed on the type of the first limiting member 1258 and the second limiting member 1259.

[0081] like Figure 8 and Figure 9 As shown, further, the first pressure member 121 includes a first connecting seat 1211, a first non-elastic pressure plate 1212, and a first elastic pressure plate 1213. The first connecting seat 1211 is connected to the fourth driving member 1252. The first non-elastic pressure plate 1212 is connected between the first elastic pressure plate 1213 and the first connecting seat 1211. The thickness of the first elastic pressure plate 1213 is less than or equal to the thickness of the first non-elastic pressure plate 1212. And / or the second pressure member 122 includes a second connecting seat 1221, a second non-elastic pressure plate 1222, and a second elastic pressure plate 1223. The second connecting seat 1221 is connected to the fifth driving member 1253. The second non-elastic pressure plate 1222 is connected between the second elastic pressure plate 1223 and the second connecting seat 1221. The thickness of the second elastic pressure plate 1223 is less than or equal to the thickness of the second non-elastic pressure plate 1222.

[0082] For example, non-elastic pressure plates can be made of metal plates, rigid plastic plates, etc., while elastic pressure plates can be made of silicone plates, rubber plates, etc., without specific limitations.

[0083] It is understood that by combining the first inelastic pressure plate 1212 and the first elastic pressure plate 1213, and controlling the thickness of the first elastic pressure plate 1213 to be less than or equal to the thickness of the first inelastic pressure plate 1212, the first pressure member 121 can stably adhere to the battery module 200 to apply pressure to the heating film 210 on one side of the battery module 200 along the first direction X. By combining the second inelastic pressure plate 1222 and the second elastic pressure plate 1223, and controlling the thickness of the second elastic pressure plate 1223 to be less than or equal to the thickness of the second inelastic pressure plate 1222, the second pressure member 122 can stably adhere to the battery module 200 to apply pressure to the heating film 210 on the other side of the battery module 200 along the first direction X.

[0084] Furthermore, the first pressurizing member 121 is slidably connected to the moving component 124 along the first direction X, and the second pressurizing member 122 is slidably connected to the moving component 124 along the first direction X.

[0085] For example, a sliding connection can be achieved through a combination of linear bearings and guide shafts, or through a combination of sliders and guide rails. For instance, a slider is provided on the first pressure member 121, and a guide rail is provided on the moving component 124; the slider slides against the guide rail, thereby achieving a sliding connection between the first pressure member 121 and the moving component 124 along the first direction X. As another example, a slider is provided on the second pressure member 122, and a guide rail is provided on the moving component 124; the slider slides against the guide rail, thereby achieving a sliding connection between the second pressure member 122 and the moving component 124 along the first direction X.

[0086] It is understandable that by sliding the first pressurizing member 121 to the moving component 124 along the first direction X, and sliding the second pressurizing member 122 to the moving component 124 along the first direction X, the stability of the first pressurizing member 121 and the second pressurizing member 122 moving under the drive of the driving member can be increased, thereby improving the effect of pressurizing the heating film 210 of the battery module 200.

[0087] like Figure 9 and Figure 10 As shown, the first connecting seat 1211 further includes a first seat plate 12111, a second seat plate 12112, a third seat plate 12113, a fourth seat plate 12114, a first reinforcing plate 12115, and a second reinforcing plate 12116. The first seat plate 12111 is connected to the fourth driving member 1252. The second seat plate 12112 is connected between the first seat plate 12111 and the third seat plate 12113. The fourth seat plate 12114 is connected to the third seat plate 12113. The first non-elastic pressure plate 1212 is connected to the fourth seat plate 12114. The first reinforcing plate 12115 is connected to the third seat plate 12113 and the fourth seat plate 12114 respectively. The second reinforcing plate 12116 is connected to the second seat plate 12112 and the fourth seat plate 12114 respectively. The fourth seat plate 12114 is located between the first reinforcing plate 12115 and the second reinforcing plate 12116.

[0088] It is understandable that the first base plate 12111 facilitates the connection between the first pressure member 121 and the fourth drive member 1252; the first reinforcing plate 12115 and the second reinforcing plate 12116 enhance the structural strength and stability of the first pressure member 121, enabling the first pressure member 121 to better pressurize the heating film 210 of the battery module 200.

[0089] like Figure 9 , Figure 11 and Figure 12As shown, the second connecting seat 1221 includes a fifth seat plate 12211, a sixth seat plate 12212, a seventh seat plate 12213, a third reinforcing plate 12214, a fourth reinforcing plate 12215, a pressure sensor 12216, and a protective cover 12217. The fifth seat plate 12211 is connected to the fifth driving member 1253. The pressure sensor 12216 is connected between the fifth seat plate 12211 and the seventh seat plate 12213. The protective cover 12217 is connected to the fifth seat plate 12211 and covers the pressure sensor 1221. 6. The sixth seat plate 12212 is connected to the seventh seat plate 12213 and is slidably connected to the moving assembly 124 along the first direction X. The third reinforcing plate 12214 is connected to the seventh seat plate 12213 and the sixth seat plate 12212 respectively. The fourth reinforcing plate 12215 is connected to the seventh seat plate 12213 and the sixth seat plate 12212 respectively. The seventh seat plate 12213 is located between the third reinforcing plate 12214 and the fourth reinforcing plate 12215. The second non-elastic pressure plate 1222 is connected to the seventh seat plate 12213.

[0090] Understandably, the fifth base plate 12211 facilitates the connection between the second pressure-applying component 122 and the fifth driving component 1253; the sixth base plate 12212 facilitates the sliding connection between the second pressure-applying component 122 and the moving component 124; the pressure sensor 12216 can detect the pressure applied by the second pressure-applying component 122 to the heating film 210 of the battery module 200 in real time, so as to determine whether the pressure applied by the second pressure-applying component 122 has reached the preset pressure. The protective cover 12217 can protect the pressure sensor 12216, thereby reducing the risk of the pressure sensor 12216 being affected by the external environment and thus reducing its accuracy; the third reinforcing plate 12214 and the fourth reinforcing plate 12215 can enhance the structural strength and structural stability of the second pressure-applying component 122, so that the second pressure-applying component 122 can better pressurize the heating film 210 of the battery module 200.

[0091] In summary, the pressurization device 100 provided in the embodiments of this application is used as follows:

[0092] First, the conveying device 300 conveys the tray containing the battery module 200 along the first direction X until the tray and the battery module 200 move to the position of the pressurizing device 100. At this time, the lifting mechanism on the conveying device 300 drives the tray and the battery module 200 to move along the third direction Z in the direction close to the fixing component 123, so that the battery module 200 is located between the first positioning component 1101 and the second positioning component 1102.

[0093] Then, the first driving member 113 drives the first positioning member 111 to move along the direction close to the second positioning member 112 in the second direction Y. At the same time, the second driving member 114 drives the second positioning member 112 to move along the direction close to the first positioning member 111 in the second direction Y, until the first positioning member 111 and the second positioning member 112 press against the two opposite sides of the battery module 200 along the second direction Y, thereby positioning the battery module 200. The third driving member 1251 drives the moving component 124 to move along the direction close to the positioning mechanism 110 in the third direction Z to a preset position. The fourth driving member 1252 drives the first pressing member 121 to move along the direction close to the second pressing member 122 in the first direction X, until the first pressing member 121 presses against the second pressing member 122. The heating film 210 on one side of the battery module 200 along the first direction X is pressed; the sixth driving member 1255 drives the blocking member 1254 to move along the third direction Z in a direction close to the first pressing member 121 until the blocking member 1254 abuts against the first pressing member 121, thereby restricting the first pressing member 121 from moving along the first direction X away from the second pressing member 122; the fifth driving member 1253 drives the second pressing member 122 to move along the first direction X in a direction close to the first pressing member 121 until the second pressing member 122 presses the heating film 210 on the other side of the battery module 200 along the first direction X, and maintains the pressure for a certain period of time after the pressure sensor 12216 detects that the second pressing member 122 has reached the preset pressure.

[0094] After pressurizing the heating film 210 of the battery module 200, the fifth driving member 1253 drives the second pressing member 122 to move in the first direction X away from the first pressing member 121; the sixth driving member 1255 drives the blocking member 1254 to move in the third direction Z away from the first pressing member 121 to release the obstruction of the first pressing member 121; the fourth driving member 1252 drives the first pressing member 121 to move in the first direction X away from the second pressing member 122; the third driving member 1251 drives the moving assembly 124 to move in the third direction Z away from the positioning mechanism 110; the second driving member 114 drives the second positioning member 112 to move in the second direction Y away from the first positioning member 111, and at the same time, the first driving member 113 drives the first positioning member 111 to move in the second direction Y away from the second positioning member 112. At this point, all restrictions on the battery module 200 are lifted, and the battery module 200 can be transported by the conveying device 300 to the next production process.
