[0061] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0062] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0063] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of the various components in the embodiments of the present application shown in the drawings are only exemplary and should not constitute any limitation to the present application.

[0064] Batteries are common electrical energy storage devices. Batteries usually include battery cells and a casing. The casing usually includes a frame assembly. The frame assembly is usually formed by connecting a plurality of beams to define a storage space. The battery cells are placed in the storage space to protect the battery cells.

[0065] In the related art, the substrate is usually first formed by a rolling process, and then the formed substrate is cut into beams of a certain length. However, the actual size of the beams made by the above process has a certain deviation compared to the preset size, which results in a larger assembly tolerance between the two interconnected beams, resulting in a larger gap between the two interconnected beams, which in turn leads to a decrease in the airtightness of the box.

[0066] In order to improve the air tightness of the box, the first connecting end of the first beam body in the frame assembly provided in the embodiment of the present application abuts against the first alignment portion of the alignment component, and the second connecting end of the second beam body abuts against the second alignment portion of the alignment component. In this way, the alignment component can absorb the assembly tolerance of the first connecting end and the second connecting end so that the first connecting end and the second connecting end can be aligned with each other, effectively reducing the gap between the first connecting end and the second connecting end, thereby effectively improving the air tightness of the box using the above-mentioned frame assembly.

[0067] The battery disclosed in the embodiment of the present application can be used for electrical equipment using the battery as a power source, or for various energy storage systems using the battery as an energy storage element. Electrical equipment can be, but is not limited to, vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and electric tools, etc. The vehicle can be a fuel vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. The spacecraft can be an airplane, a rocket, a space shuttle, or a spacecraft, etc. The electric toy can be a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The electric tool can be a metal cutting electric tool, a grinding electric tool, an assembly electric tool, and a railway electric tool, for example, an electric drill, an electric grinder, an electric wrench, an electric screwdriver, an electric hammer, an impact drill, a concrete vibrator, and an electric planer, etc.

[0068] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device in an embodiment of the present application.

[0069] See also Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle 1000 provided in an embodiment of the present application. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be provided at the bottom, head, or tail of the vehicle 1000. The battery 100 can be used to power the vehicle 1000, for example, the battery 100 can be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating, and driving the vehicle 1000.

[0070] In some embodiments of the present application, the battery 100 can not only serve as an operating power source for the vehicle 1000, but also serve as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0071] See also Figure 2 , Figure 2Schematic diagram of an explosion of a battery 100 provided in an embodiment of the present application. The battery 100 includes a box 10 and a battery cell 20, and the battery cell 20 is contained in the box 10. Among them, the box 10 is used to provide a storage space 134 for the battery cell 20, and the box 10 can adopt a variety of structures. In some embodiments, the box 10 may include a first part 11 and a second part 12, and the first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define a storage space 134 for accommodating the battery cell 20. The second part 12 may be a hollow structure with one end open, and the first part 11 may be a plate-like structure, and the first part 11 is covered on the open side of the second part 12, so that the first part 11 and the second part 12 jointly define the storage space 134; the first part 11 and the second part 12 may also be hollow structures with one side open, and the open side of the first part 11 is covered on the open side of the second part 12. Of course, the box 10 formed by the first part 11 and the second part 12 can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0072] In some embodiments, the box body 10 includes a bottom plate, a cover plate and a frame assembly 13, wherein the bottom plate is covered on one side of the frame assembly 13, and the cover plate is covered on the other side of the frame assembly 13. The frame assembly 13 is a supporting component of the box body 10, and the frame assembly 13 includes a plurality of beams, which are connected end to end to define the above-mentioned accommodation space 134. The bottom plate is used to close the bottom of the frame assembly 13, and also plays a protective role for the bottom of the battery cell 20. The cover plate is used to close the top of the frame assembly 13. A heat exchange structure may be provided on the bottom plate, or on the cover plate, or on both the bottom plate and the cover plate. The heat exchange structure is used to absorb the heat generated by the operation of the battery cell 20 or transfer the heat to the battery cell 20, so as to adjust the temperature of the battery cell 20.

[0073] As an example, the cover plate alone constitutes the first part 11 of the box body 10 , and the frame assembly 13 and the bottom plate together constitute the second part 12 of the box body 10 .

[0074] As another example, the frame assembly 13 and the cover plate together constitute the first part 11 of the box body 10 , and the bottom plate alone constitutes the second part 12 of the box body 10 .

[0075] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box 10. Of course, the battery 100 may also be a battery module formed by first connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and then accommodated in the box 10.

[0076] Each battery cell 20 may be a secondary battery cell or a primary battery cell, wherein a secondary battery cell refers to a battery cell 20 that can be used continuously by activating active materials by charging after the battery cell 20 is discharged, and a primary battery cell refers to a battery cell 20 that cannot be used continuously by activating active materials by charging after the power of the battery cell 20 is exhausted; the battery cell 20 may also be a lithium ion battery cell, a sodium ion battery cell, a sodium lithium ion battery cell, a lithium metal battery cell, a sodium metal battery cell, a lithium sulfur battery cell, a magnesium ion battery cell, a nickel hydrogen battery cell, a nickel cadmium battery cell, a lead storage battery cell, etc., but is not limited thereto.

[0077] Of course, in some embodiments, the battery 100 may not include the housing 10 , but rather a plurality of battery cells 20 may be electrically connected and formed into a whole through necessary fixing structures and then assembled into the vehicle 1000 .

[0078] In order to illustrate the technical solution provided by the present application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0079] First, please also refer to Figures 3 to 7 The embodiment of the present application provides a frame assembly 13, including a first beam body 131, a second beam body 132 and an alignment member 133, the first beam body 131 has a first connection end 1311, the second beam body 132 has a second connection end 1321, the alignment member 133 includes a first alignment member 1331, the first alignment member 1331 includes a first alignment portion 13311 and a second alignment portion 13312 connected to each other, the first alignment portion 13311 abuts against the first connection end 1311 and the second alignment portion 13312 abuts against the second connection end 1321, so that the first connection end 1311 is aligned with the second connection end 1321.

[0080] The first beam body 131 and the second beam body 132 are any two adjacent beam bodies in the frame assembly 13. The first beam body 131 can be arranged at an angle with the second beam body 132, or can be arranged parallel to the second beam body 132. In some embodiments, the first beam body 131 and the second beam body 132 can both be integrally formed components, for example, the first beam body 131 and the second beam body 132 are integrally formed by a rolling process.

[0081] The first connection end 1311 of the first beam body 131 refers to the end of the first beam body 131 close to the second beam body 132, and the second connection end 1321 of the second beam body 132 refers to the end of the second beam body 132 close to the first beam body 131. The first connection end 1311 is connected to the second connection end 1321, and the connection method between the first connection end 1311 and the second connection end 1321 can be but is not limited to welding, bonding, etc.

[0082] In some embodiments, the number of first beam bodies 131 and the number of second beam bodies 132 are both multiple, and the first beam bodies 131 and the second beam bodies 132 both include a first connection end 1311 and a second connection end 1321, the first connection end 1311 of a first beam body 131 is connected to the second connection end 1321 of a second beam body 132, and the second connection end 1321 of the first beam body 131 is connected to the first connection end 1311 of another second beam body 132.

[0083] The alignment member 133 is a component used to limit the relative position of the first connection end 1311 and the second connection end 1321. Under the limiting effect of the alignment member 133, the first connection end 1311 and the second connection end 1321 can be aligned with each other in at least one direction. In order to enable the alignment member 133 to effectively limit the relative position of the first connection end 1311 and the second connection end 1321, the alignment member 133 can be made of a rigid material, and the rigid material can be but is not limited to aluminum, aluminum alloy, stainless steel, copper, iron, hard plastic, etc. Among them, the first alignment portion 13311 is a portion used to limit the position of the first connection end 1311, and the second alignment portion 13312 is a portion used to limit the position of the second connection end 1321. It can be understood that the first alignment portion 13311 abuts against the first connection end 1311, and the second alignment portion 13312 abuts against the second connection end 1321. In other words, the first alignment portion 13311 can apply a certain supporting force to the first connection end 1311. Similarly, the second alignment portion 13312 can apply a certain supporting force to the second connection end 1321, so that at least one of the first connection end 1311 and the second connection end 1321 is displaced under the action of the corresponding supporting force, so that the first connection end 1311 and the second connection end 1321 are aligned with each other.

[0084] In some embodiments, the first alignment portion 13311 abuts against the outer peripheral wall of the first connection end 1311, so that the direction of the supporting force exerted by the first alignment portion 13311 on the first connection end 1311 is not parallel to the length direction of the first beam body 131. Similarly, the second alignment portion 13312 abuts against the outer peripheral wall of the second connection end 1321, so that the direction of the supporting force exerted by the second alignment portion 13312 on the second connection end 1321 is not parallel to the length direction of the second beam body 132.

[0085] In the frame assembly 13 provided in the embodiment of the present application, the first connection end 1311 of the first beam body 131 abuts against the first alignment portion 13311 of the alignment member 133, and the second connection end 1321 of the second beam body 132 abuts against the second alignment portion 13312 of the alignment member 133. In this way, the alignment member 133 can absorb the assembly tolerance of the first connection end 1311 and the second connection end 1321 so that the first connection end 1311 and the second connection end 1321 can be aligned with each other, effectively reducing the gap between the first connection end 1311 and the second connection end 1321, thereby effectively improving the air tightness of the box body 10 using the above-mentioned frame assembly 13.

[0086] In some embodiments of this application, please refer to Figures 3 to 7 The first alignment portion 13311 abuts against the first connection end 1311 along a first direction, and the second alignment portion 13312 abuts against the second connection end 1321 along a second direction. The first direction and the second direction are parallel to the reference plane, so that the first connection end 1311 and the second connection end 1321 are aligned along a direction parallel to the reference plane.

[0087] The first direction may be any direction parallel to the reference plane but not parallel to the length direction of the first beam 131. Similarly, the second direction may be any direction parallel to the reference plane but not parallel to the length direction of the second beam 132. In some embodiments, the reference plane may be the placement plane of the box 10, that is, the reference plane is perpendicular to the height direction of the box 10 (e.g. Figure 3 Z direction as shown).

[0088] The first alignment portion 13311 abuts against the first connection end 1311 along the first direction, that is, the first alignment portion 13311 can apply a supporting force to the first connection end 1311 along the first direction. Similarly, the second alignment portion 13312 abuts against the second connection end 1321 along the second direction, that is, the second alignment portion 13312 can apply a supporting force to the second connection end 1321 along the second direction. The first direction and the second direction can be two non-parallel directions or the same direction.

[0089] In some embodiments, when the first beam body 131 and the second beam body 132 are arranged at an angle to each other, the first alignment portion 13311 and the second alignment portion 13312 are also arranged at an angle to each other, and accordingly, the first direction and the second direction are two non-parallel directions.

[0090] In other embodiments, when the first beam 131 and the second beam 132 are arranged parallel to each other, the first alignment portion 13311 and the second alignment portion 13312 are also arranged parallel to each other, and accordingly, the first direction and the second direction are parallel to each other, that is, the first direction and the second direction are the same direction.

[0091] By adopting the above technical solution, the alignment component 133 can absorb the assembly tolerance of the first connection end 1311 and the second connection end 1321 along the direction parallel to the reference plane, so that the first connection end 1311 and the second connection end 1321 are aligned along the direction parallel to the reference plane, effectively reducing the gap between the first connection end 1311 and the second connection end 1321, thereby effectively improving the air tightness of the box body 10 adopting the above frame assembly 13.

[0092] In some embodiments of this application, please refer to Figures 3 to 7 The alignment member 133 also includes a second alignment member 1332 connected to the first alignment member 1331, and the second alignment member 1332 abuts against the first connection end 1311 and the second connection end 1321 along a third direction to align the first connection end 1311 with the second connection end 1321 along the third direction, wherein the third direction intersects with the reference plane.

[0093] The second alignment member 1332 is a member used to limit the relative position of the first connection end 1311 and the second connection end 1321 along the third direction. The second alignment member 1332 abuts against the first connection end 1311 and the second connection end 1321 along the third direction, that is, the second alignment member 1332 can apply a supporting force to the first connection end 1311 and the second connection end 1321 along the third direction, so that the first connection end 1311 and the second connection end 1321 are aligned along the third direction. The third direction can be any direction intersecting with the above-mentioned reference plane, that is, the third direction is not parallel to the above-mentioned first direction and the above-mentioned second direction. The second alignment piece 1332 and the first alignment piece 1331 can be an integrally formed component. For example, the second alignment piece 1332 and the first alignment piece 1331 are integrally formed by a stamping process. The second alignment piece 1332 and the first alignment piece 1331 can also be separately formed and then connected into a whole. The connection method between the second alignment piece 1332 and the first alignment piece 1331 can be but is not limited to welding, bonding, fastening connection, etc.

[0094] By adopting the above technical solution, the alignment component 133 can simultaneously absorb the assembly tolerances of the first connection end 1311 and the second connection end 1321 along the direction parallel to the reference plane and the third direction, not only making the first connection end 1311 and the second connection end 1321 aligned along the direction parallel to the reference plane, but also making the first connection end 1311 and the second connection end 1321 aligned with each other along the third direction, further reducing the gap between the first connection end 1311 and the second connection end 1321, thereby further improving the air tightness of the box body 10 adopting the above frame assembly 13.

[0096] By adopting the above-mentioned technical solution, the alignment member 133 can limit the relative position of the first connection end 1311 and the second connection end 1321 in the positive and reverse directions along the third direction at the same time, so as to more effectively absorb the assembly tolerance of the first connection end 1311 and the second connection end 1321 along the third direction, further reduce the gap between the first connection end 1311 and the second connection end 1321, thereby further improving the air tightness of the box body 10 adopting the above-mentioned frame assembly 13.

[0097] In some embodiments of the present application, the third direction is parallel to the height direction of the frame assembly 13 and perpendicular to the reference plane.

[0098] In other words, in this embodiment, the second alignment member 1332 can abut against the top wall of the first connection end 1311 and the top wall of the second connection end 1321, or can abut against the bottom wall of the first connection end 1311 and the bottom wall of the second connection end 1321, and the first alignment portion 13311 can abut against the side wall of the first connection end 1311 close to the above-mentioned accommodating space 134 or the side wall of the first connection end 1311 away from the above-mentioned accommodating space 134, and the second alignment portion 13312 can abut against the side wall of the second connection end 1321 close to the above-mentioned accommodating space 134 or the side wall of the second connection end 1321 away from the above-mentioned accommodating space 134.

That is to say, the first alignment member 1331 and the second alignment member 1332 are both applying a supporting force to the first connection end 1311 from the inside of the first cavity 13111 to the outside of the first connection end 1311.

The second alignment portion 13312 and / or the second alignment member 1332 can be inserted into the second cavity 13211 along the introduction direction of the second introduction member 1333.

[0108] The second guide member 1333 is a component for guiding the second alignment portion 13312 and / or the second alignment member 1332 into the second cavity 13211. The second guide member 1333 can be connected to a side of the second alignment portion 13312 close to the second connection end 1321, can also be connected to a side of the second alignment member 1332 close to the second connection end 1321, and can also be connected to both a side of the second alignment portion 13312 close to the second connection end 1321 and a side of the second alignment member 1332 close to the second connection end 1321.

[0111] By adopting the above technical solution, it is convenient to insert the first alignment portion 13311 into the first cavity 13111 and the second alignment portion 13312 into the second cavity 13211 , thereby further improving the assembly efficiency of the frame assembly 13 .

[0112] In some embodiments of this application, please refer to Figure 7 The alignment component 133 has an alignment cavity 1334 , and the first connection end 1311 and the second connection end 1321 are inserted into the alignment cavity 1334 .

[0113] The alignment cavity 1334 may be formed by enclosing the first alignment member 1331 and the second alignment member 1332 . When there are two second alignment members 1332 , the alignment cavity 1334 is located between the two second alignment members 1332 .

[0114] It can be understood that after the first connection end 1311 is inserted into the alignment cavity 1334, the first alignment member 1331 and the second alignment member 1332 abut against the first connection end 1311. Similarly, after the second connection end 1321 is inserted into the alignment cavity 1334, the first alignment member 1331 and the second alignment member 1332 abut against the second connection end 1321. In other words, the first alignment member 1331 and the second alignment member 1332 both abut against the outer wall surface of the first connection end 1311 and the outer wall surface of the second connection end 1321, so as to apply a supporting force to the first connection end 1311 and the second connection end 1321 at the outside of the first connection end 1311 and the outside of the second connection end 1321.

[0115] By adopting the above technical solution, it is convenient for the alignment component 133 to align the first connection end 1311 and the second connection end 1321 , thereby effectively improving the assembly efficiency of the frame assembly 13 .

[0116] In some embodiments of the present application, when the number of the first beam bodies 131 and the number of the second beam bodies 132 are both plural, the number of the alignment members 133 is plural, and the adjacent first connection ends 1311 and the second connection ends 1321 constitute a connection structure, a part of the alignment members 133 is arranged in a one-to-one correspondence with a part of the connection structure and is inserted into the first cavity 13111 and the second cavity 13211 in the corresponding connection structure, and another part of the alignment members 133 has an alignment cavity 1334 and is arranged in a one-to-one correspondence with the other part of the connection structure, and the alignment cavity 1334 is used for the corresponding connection structure to be inserted.

[0117] In some embodiments of this application, please refer to Figure 6 The first connection end 1311 includes a first wall 13112 abutting against the second alignment piece 1332, and the second connection end 1321 includes a second wall 13212 abutting against the second alignment piece 1332. The first wall 13112 and the second wall 13212 are welded to form a first weld mark 135, and the second alignment piece 1332 covers at least a portion of the first weld mark 135.

[0118] When the third direction is parallel to the height direction of the frame assembly 13 and perpendicular to the reference plane, the first wall 13112 can be the top wall or bottom wall of the first connection end 1311 , and the second wall 13212 can be the top wall or bottom wall of the second connection end 1321 .

[0119] In some embodiments, the number of first walls 13112 is two, one first wall 13112 is the top wall of the first connection end 1311, and the other first wall 13112 is the bottom wall of the first connection end 1311. Correspondingly, the number of second walls 13212 is two, one second wall 13212 is the top wall of the second connection end 1321, and the other second wall 13212 is the bottom wall of the second connection end 1321. The number of second alignment members 1332 is two, two The second alignment member 1332 is disposed on two opposite sides of the first alignment member 1331 along the third direction, the top wall of the first connection end 1311 and the top wall of the second connection end 1321 are welded to form a first weld mark 135, and one second alignment member 1332 covers at least a portion of the aforementioned first weld mark 135, the bottom wall of the first connection end 1311 and the bottom wall of the second connection end 1321 are welded to form the first weld mark 135, and another second alignment member 1332 covers at least a portion of the aforementioned first weld mark 135.

[0120] The second alignment member 1332 covers at least a portion of the first weld mark 135. The second alignment member 1332 may be in contact with the first weld mark 135 or may be separated from the first weld mark 135 by a small distance. In some embodiments, the second alignment member 1332 covers the entire first weld mark 135 and is in contact with the first weld mark 135.

[0121] In the related art, since the thickness of the wall of the first beam body 131 and the thickness of the wall of the second beam body 132 are relatively small, when the first connection end 1311 and the second connection end 1321 are welded, the wall of the first beam body 131 and the wall of the second beam body 132 are easily welded through, resulting in poor welding, causing a decrease in the connection strength between the first connection end 1311 and the second connection end 1321.

[0122] By adopting the above technical solution, when welding through occurs during the welding process of the first wall body 13112 and the second wall body 13212, the second alignment member 1332 can be used as a reinforcement component to fill the welding through portion of the first weld mark 135, thereby effectively improving the welding strength between the first connection end 1311 and the second connection end 1321.

[0123] In some embodiments of the present application, the second alignment member 1332 is connected to the first connection end 1311 and to the second connection end 1321 .

[0125] In other embodiments, when the alignment member 133 has an alignment cavity 1334, the first connection end 1311 can be first inserted into the alignment cavity 1334 and the second alignment member 1332 can be connected to the first connection end 1311, and then the second connection end 1321 can be inserted into the alignment cavity 1334 and the second alignment member 1332 can be connected to the second connection end 1321.

[0126] The connection method between the second alignment member 1332 and the first connection end 1311 can be but is not limited to welding, bonding, etc. Similarly, the connection method between the second alignment member 1332 and the second connection end 1321 can be but is not limited to welding, bonding, etc.

[0127] By adopting the above technical solution, the first connection end 1311 and the second connection end 1321 can be pre-fixed, which is convenient for the subsequent connection of the first connection end 1311 and the second connection end 1321 .

[0131] By adopting the above technical solution, it is convenient to connect the second alignment member 1332 to the first connection end 1311 and to connect the second alignment member 1332 to the second connection end 1321 .

[0132] In some embodiments of this application, please refer to Figure 6The first connection end 1311 includes a third wall 13113 abutting against the first alignment portion 13311, and the second connection end 1321 includes a fourth wall 13213 abutting against the second alignment portion 13312. The third wall 13113 and the fourth wall 13213 are welded to form a second weld mark, and the first alignment member 1331 covers at least part of the second weld mark.

[0133] When the third direction is parallel to the height direction of the frame assembly 13 and perpendicular to the reference plane, the third wall 13113 can be the side wall of the first connection end 1311 close to the above-mentioned accommodating space 134 or the side wall away from the above-mentioned accommodating space 134, and the fourth wall 13213 can be the side wall of the second connection end 1321 close to the above-mentioned accommodating space 134 or the side wall away from the above-mentioned accommodating space 134.

The side wall of the first connection end 1311 away from the above-mentioned accommodating space 134 and the side wall of the second connection end 1321 away from the above-mentioned accommodating space 134 are welded to form a second weld mark.

[0135] The first alignment member 1331 covers at least part of the second weld mark, and the first alignment member 1331 may be in contact with the second weld mark or may be separated from the second weld mark by a small distance. In some embodiments, the first alignment member 1331 covers the entire second weld mark and is in contact with the second weld mark.

[0136] In the related art, since the thickness of the wall of the first beam body 131 and the thickness of the wall of the second beam body 132 are relatively small, when the first connection end 1311 and the second connection end 1321 are welded, the wall of the first beam body 131 and the wall of the second beam body 132 are easily welded through, resulting in poor welding, causing a decrease in the connection strength between the first connection end 1311 and the second connection end 1321.

[0137] By adopting the above technical solution, when welding through occurs during the welding process of the third wall body 13113 and the fourth wall body 13213, the first alignment member 1331 can be used as a reinforcement component to fill the weld through portion of the second weld mark, thereby effectively improving the welding strength between the first connection end 1311 and the second connection end 1321.

[0138] In some embodiments of the present application, the first alignment portion 13311 is connected to the first connection end 1311 , and the second alignment portion 13312 is connected to the second connection end 1321 .

[0140] In other embodiments, when the alignment member 133 has an alignment cavity 1334, the first connection end 1311 can be inserted into the alignment cavity 1334 and the first alignment portion 13311 can be connected to the first connection end 1311, and then the second connection end 1321 can be inserted into the alignment cavity 1334 and the second alignment portion 13312 can be connected to the second connection end 1321.

[0141] The connection method between the first alignment portion 13311 and the first connection end 1312 may be, but is not limited to, welding, bonding, etc. Similarly, the connection method between the second alignment portion 13312 and the second connection end 1321 may be, but is not limited to, welding, bonding, etc.

[0142] By adopting the above technical solution, the first connection end 1311 and the second connection end 1321 can be pre-fixed, which is convenient for the subsequent connection of the first connection end 1311 and the second connection end 1321 .

[0143] In some embodiments of the present application, the first alignment portion 13311 is welded to the first connection end 1311 .

[0148] It can be understood that the angle between the first beam body 131 and the second beam body 132 can be determined according to actual application requirements. For example, the angle between the first beam body 131 and the second beam body 132 can be 90°, 120°, 150°, etc.

[0149] By adopting the above technical solution, the angle formed by the first alignment portion 13311 and the second alignment portion 13312 can be adapted to the angle formed by the first beam body 131 and the second beam body 132, so that the first alignment member 1331 can more quickly and accurately align the first connection end 1311 and the second connection end 1321, further reducing the gap between the first connection end 1311 and the second connection end 1321, and further improving the air tightness of the box body 10 using the above frame assembly 13.
