Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0053] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication 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.

[0055] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0056] In the embodiments of this application, the same reference numerals denote 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 various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0057] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0058] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0059] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0060] In some embodiments, the battery cell may include a casing. The casing may be a steel casing, an aluminum casing, a plastic casing (such as a polypropylene casing), a composite metal casing (such as a copper-aluminum composite casing), or an aluminum-plastic film, etc. In some embodiments, the casing may be a sealed structure or a non-sealed structure. As an example, when the casing is a non-sealed structure, the casing serves to protect the electrode assembly, and a sealing bag is included between the casing and the electrode assembly to encapsulate the electrode assembly and electrolyte. Specifically, the sealing bag may be a bag-shaped insulating component or an aluminum-plastic film. When the casing is a sealed structure, it is used to encapsulate components such as the electrode assembly and electrolyte.

[0061] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0062] In some embodiments, at least one electrode terminal is provided on the housing, and the electrode terminal is electrically connected to the tab. The electrode terminal can be directly connected to the tab, or it can be indirectly connected to the tab through a current collector. The electrode terminal can be provided on the end cap or on the housing.

[0063] In some embodiments, a pressure relief mechanism is provided on the casing. The pressure relief mechanism is used to release the internal gas of the battery cell.

[0064] As an example, the internal pressure or temperature of a battery cell is actuated to release the internal pressure or temperature when it reaches a predetermined threshold. When the internal pressure or temperature of the battery cell reaches the predetermined threshold, the pressure relief mechanism is activated or a weak structure in the pressure relief mechanism is broken, thereby creating an opening or channel for the internal pressure or temperature to be released. The threshold design varies depending on the design requirements. The threshold may depend on the materials of one or more of the positive electrode, negative electrode, electrolyte, and separator in the battery cell.

[0065] As an example, the pressure relief mechanism can be integrally molded with the housing.

[0066] As an example, the pressure relief mechanism can also be separately installed and connected to the housing.

[0067] The term "actuation" as used in this application refers to the activation or actuation of the pressure relief mechanism to a certain state, thereby releasing the internal pressure and temperature of the battery cell. The actions of the pressure relief mechanism may include, but are not limited to: movement of components within the mechanism to form an exhaust channel, rupture, breakage, tearing, or opening of at least a portion of the mechanism, etc. When the pressure relief mechanism is activated, the high-temperature, high-pressure substances inside the battery cell are discharged as waste from the activated portion. This method allows for pressure and temperature relief of the battery cell under controllable pressure or temperature, thereby preventing potentially more serious accidents.

[0068] In some embodiments, when the housing is a non-sealed structure, the pressure relief mechanism can be configured as a through hole for venting gas inside the battery cell.

[0069] The emissions from battery cells mentioned in this application include, but are not limited to: electrolyte, dissolved or split positive and negative electrode plates, fragments of separators, high-temperature and high-pressure gases generated by the reaction, flames, etc.

[0070] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0071] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0072] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0073] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cell assemblies housed within the housing.

[0074] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0075] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0076] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0077] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0078] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0079] The technical solutions described in the embodiments of this application are applicable to various electrical devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0080] Energy conservation and emission reduction are crucial for the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a critical factor in their development. During vibration or impact testing of the battery packs under the vehicle chassis of new energy vehicles, assembly equipment is required for the installation and removal of the battery packs. Current assembly equipment is limited to a wide range of products, requires manual installation and measurement, has poor compatibility with products of different sizes and structures, and suffers from low installation accuracy due to manual installation methods. Therefore, improving the performance of this assembly equipment has become a pressing technical problem to be solved in this field.

[0081] Therefore, this application provides an assembly device, which includes an assembly platform and an assembly component. The assembly platform includes a first wall and a first receiving cavity. The assembly component is located in a first mounting area and is used to bolt a beam component corresponding to the battery device to the first wall in the first mounting area. The beam component is attached to a first surface of the first wall away from the first receiving cavity. The first wall is provided with N first through holes penetrating the first wall along its thickness direction. The beam component includes a second wall facing the first surface. The second wall is provided with M second through holes penetrating the second wall along its thickness direction. The beam component is bolted to the first wall through the first and second through holes. On a plane perpendicular to the thickness direction of the first wall, the orthographic projections of the M second through holes overlap with the orthographic projections of the M first through holes. N is greater than M, and both N and M are positive integers greater than or equal to 2. Thus, in this embodiment, by configuring the assembly device to include an assembly platform and an assembly component, the assembly component is used to bolt the beam component corresponding to the battery device to the first wall in the first mounting area. The first wall has N first through holes penetrating the first wall along its thickness direction. The beam component includes a second wall facing the first surface, and the second wall has M second through holes penetrating the second wall along its thickness direction. The beam component and the first wall are bolted together through the first and second through holes. On a plane perpendicular to the thickness direction of the first wall, the orthographic projections of the M second through holes overlap with the orthographic projections of the M first through holes, where N is greater than M. This allows the assembly platform to accommodate beam components of different sizes, improving the product compatibility of the assembly device. Furthermore, by providing N first through holes on the first wall of the assembly platform, the number of first through holes is greater than the number of second through holes, reducing the weight of the assembly platform and facilitating its movement, thereby improving the performance of the assembly device.

[0082] It should be understood that the technical solutions described in the embodiments of this application are not limited to the electrical devices described above, but can also be applied to all devices that use batteries. For the sake of simplicity, the following embodiments will be described in detail using a vehicle as an example of an electrical device.

[0083] For example, such as Figure 1The diagram shown is a structural schematic of a vehicle 1 according to one embodiment of this application. Vehicle 1 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A motor 40, a controller 30, and a battery device 10 can be installed inside vehicle 1. The controller 30 controls the battery device 10 to supply power to the motor 40. For example, the battery device 10 can be installed at the bottom, front, or rear of vehicle 1. The battery device 10 can be used to power vehicle 1. For example, the battery device 10 can serve as the operating power source for vehicle 1, for example, to meet the electrical system requirements of vehicle 1, such as for starting, navigation, and operation. In another embodiment of this application, the battery device 10 can not only serve as the operating power source for vehicle 1, but also as the driving power source for vehicle 1, replacing or partially replacing gasoline or natural gas to provide driving power for vehicle 1.

[0084] To meet different power demands, the battery device 10 in this embodiment may include at least one battery cell assembly, which comprises multiple battery cells. These multiple battery cells can be electrically connected in series, parallel, or a combination thereof to form the battery device 10. A combination of series and parallel connections is used. The battery device 10 may also be referred to as a battery pack. For example, multiple battery cells can first be connected in series, parallel, or a combination to form a battery module, and then multiple battery modules can be connected in series, parallel, or a combination thereof to form the battery device 10. That is, multiple battery cells can directly form the battery device 10, or they can first be assembled into battery modules, and then the battery modules can be assembled into the battery device 10.

[0085] For example, such as Figure 2 The diagram shown is a structural schematic of a battery device 10 according to an embodiment of this application. The battery device 10 may include a plurality of battery cells 20. The battery device 10 may also include a housing 11 (or cover), the housing 11 having a hollow structure, and the plurality of battery cells 20 are housed within the housing 11. For example, the plurality of battery cells 20 may be connected in parallel, in series, or in a mixed configuration and then placed within the housing 11.

[0086] like Figure 2As shown, the housing 11 may include two parts, referred to here as the first structure 111 and the second structure 112, which are fastened together. The shapes of the first structure 111 and the second structure 112 can be determined according to the combined shape of multiple battery cells 20. Both the first structure 111 and the second structure 112 may have an opening. For example, both the first structure 111 and the second structure 112 can be hollow cuboids with only one open face each. The openings of the first structure 111 and the second structure 112 are opposite to each other, and the first structure 111 and the second structure 112 are fastened together to form a housing 11 with a closed cavity. The second structure 112 may include a bottom plate 112a, a side plate 112b, and a beam. Multiple battery cells 20 are connected in parallel, series, or mixed configurations and placed inside the housing 11 formed by the fastening of the first structure 111 and the second structure 112.

[0087] Optionally, the battery device 10 may also include other structures, which will not be described in detail here. For example, the battery device 10 may also include a busbar component for realizing the electrical connection between multiple battery cells 20, such as parallel, series, or mixed connection. Specifically, the busbar component can realize the electrical connection between battery cells 20 by connecting the electrode terminals of the battery cells 20. Further, the busbar component can be fixed to the electrode terminals of the battery cells 20 by welding. The electrical energy of the multiple battery cells 20 can be further led out through the housing by a conductive mechanism. Optionally, the conductive mechanism may also be part of the busbar component.

[0088] The number of battery cells 20 can be set to any value depending on different power requirements. Multiple battery cells 20 can be connected in series, parallel, or mixed to achieve a larger capacity or power. Since each battery device 10 may include a large number of battery cells 20, for ease of installation, the battery cells 20 can be grouped, with each group of battery cells 20 forming a battery module. The number of battery cells 20 included in a battery module is unlimited and can be set according to requirements.

[0089] In this embodiment, the number of battery cells 20 can be set to any value according to different power requirements. Multiple battery cells 20 can be connected in series, parallel, or mixed connection to achieve a larger capacity or power. Since each battery device 10 may include a large number of battery cells 20, for ease of installation, the battery cells 20 can be grouped, with each group of battery cells 20 forming a battery module.

Figure 4 A partial structural schematic diagram of the assembly device 5 provided in one embodiment of this application is shown. Figure 5 A partial structural schematic diagram of the assembly device 5 provided in another embodiment of this application is shown. Figure 6 A partial structural schematic diagram of the assembly device 5 provided in another embodiment of this application is shown.

[0091] In some implementations, such as Figures 3 to 6 As shown, the assembly device 5 includes an assembly platform 510 and an assembly component 520. The assembly platform 510 includes a first wall 511 and a first receiving cavity 512. The assembly component 520 is located in a first mounting area 521. The assembly component 520 is used to bolt the beam component 530 corresponding to the battery device 10 to the first wall 511 in the first mounting area 521. The beam component 530 is attached to a first surface 513 of the first wall 511 away from the first receiving cavity 512. The first wall 511 is provided with a through-hole extending through the thickness direction of the first wall 511. The beam component 530 includes N first through holes 514 and a second wall 531 facing the first surface 513. The second wall 531 is provided with M second through holes 532 extending through the second wall 531 along its thickness direction. The beam component 530 and the first wall 511 are bolted together through the first through holes 514 and the second through holes 532. On a plane perpendicular to the thickness direction of the first wall 511, the orthographic projections of the M second through holes 532 and the orthographic projections of the M first through holes 514 overlap each other. N is greater than M, and both N and M are positive integers greater than or equal to 2.

[0092] It should be understood that, such as Figure 3 , Figure 4 and Figure 6 As shown, the assembly platform 510 in this embodiment may include a first wall 511 and a first receiving cavity 512, wherein the first receiving cavity 512 may be... Figure 3 , Figure 4 and Figure 6 The three-ended opening cavity is shown, and the first wall 511 can be an integral plate structure, or the middle region of the first wall 511 can also have a through hole structure 517 to reduce the weight of the assembly platform 510 and facilitate the movement of the assembly platform 510.

[0093] It should also be understood that the assembly component 520 is disposed in the first mounting area 521 to complete the bolt connection between the first wall 511 and the beam component 530 in the first mounting area 521. Exemplarily, the assembly component 520 can be a robotic arm, and the number of robotic arms can be set according to actual needs; this embodiment does not limit this. It should also be understood that the first mounting area 521 is further provided with a guide rail component 516, and the bottom of the assembly platform 510 is provided with a roller component 515, which can move to the first mounting area 521 via the guide rail component 516. It should also be understood that the assembly component 520 in this embodiment can be used for installation or disassembly.

[0094] It should also be understood that a first limiting member 522 is provided at the end of the guide rail component 516 away from the assembly platform 510. This first limiting member 522 is used to limit the displacement of the assembly platform 510 in the first mounting area 521. The shape of the first limiting member 522 can be set according to actual needs; for example, it can be... Figure 3 The wedge-shaped structure shown in the image.

[0095] It should also be understood that the first surface 513 of the beam component 530, which is attached to the first wall 511 and is away from the first receiving cavity 512, can mean that the beam component 530 is in direct contact with the first surface 513 but is not fixedly connected.

[0096] It should also be understood that the shape of the first through hole 514 provided on the first wall 511 can be set according to actual needs. On a plane perpendicular to the thickness direction of the first wall 511, the shape of the first through hole 514 can be circular, elliptical, polygonal, rectangular, etc. It should also be understood that the number of first through holes 514 provided on each first wall 511 can be set according to actual needs; for example, the first wall 511 can be provided with one or more of the aforementioned first through holes 514. Correspondingly, the shape of the second through hole 532 provided on the second wall 531 can be set according to actual needs. On a plane perpendicular to the thickness direction of the second wall 531, the shape of the second through hole 532 can be circular, elliptical, polygonal, rectangular, etc. It should also be understood that the number of second through holes 532 provided on each second wall 531 can be set according to actual needs; for example, the second wall 531 can be provided with one or more of the aforementioned second through holes 532.

[0097] It should be noted that the shapes of the first through hole 514 and the second through hole 532 need to be matched so that the first wall 511 and the bracket component 570 can be threaded together.

[0098] It should also be understood that the assembly device 5 further includes a second limiting member 536, which is bolted to the beam member 530 to limit the displacement of the beam member 530 on the first wall. The shape of the second limiting member 536 can be set according to actual needs.

[0099] In this embodiment, the assembly device 5 is configured to include an assembly platform 510 and an assembly component 520. The assembly component 520 is used to bolt the beam component 530 corresponding to the battery device 10 to the first wall 511 in the first mounting area 521. The first wall 511 is provided with N first through holes 514 penetrating the first wall 511 along its thickness direction. The beam component 530 includes a second wall 531 facing the first surface 513. The second wall 531 is provided with M second through holes 532 penetrating the second wall 531 along its thickness direction. The beam component 530 and the first wall 511 are connected by the first through holes 532. The hole 514 and the second through hole 532 are bolted together. On a plane perpendicular to the thickness direction of the first wall 511, the orthographic projections of the M second through holes 532 and the M first through holes 514 overlap each other, and N is greater than M. This allows the assembly platform 510 to be compatible with beam components 530 of different sizes, thereby improving the product compatibility of the assembly device 5. Furthermore, by providing N first through holes 514 on the first wall 511 of the assembly platform 510, the number of first through holes 514 is greater than the number of second through holes 532, which can reduce the weight of the assembly platform 510, making it easier to move and thus improving the performance of the assembly device 5.

[0100] In some implementations, such as Figure 3 , Figure 5 and Figure 6 As shown, the assembly device 5 also includes a first detection component 540, which is used to detect the torque value between the beam component 530 and the first wall 511 during the bolt connection process.

[0101] It should be understood that the first detection component 540 in this embodiment can be separately disposed in the first installation area 521, or the first detection component 540 can be integrated into the interior of the assembly component 520. That is, during the process of bolting the first wall 511 and the beam component 530 to the assembly component 520, the first detection component 540 can detect the torque between the beam component 530 and the first wall 511 during the bolting process.

[0102] It should be noted that the range of torque K1 during the bolt connection process between the beam component 530 and the first wall 511 in this embodiment of the application satisfies: 0 N·m ≤ K1 ≤ 200 N·m. For example, if the threshold torque for the bolt connection between the beam component 530 and the first wall 511 is set to 200 N·m, and the assembly component 520 detects a torque value reaching 200 N·m during the bolt connection process between the beam component 530 and the first wall 511, then the assembly component 520 stops assembling.

[0103] In this embodiment, by configuring the assembly device 5 to include a first detection component 540, which is used to detect the torque value between the beam component 530 and the first wall 511 during the bolt connection process, that is, during the bolt connection process between the beam component 530 and the first wall 511 by the assembly component 520, the first detection component 540 can detect the change in the torque value during the bolt connection process, so as to stop the bolt connection when the torque value reaches a preset threshold, thereby improving the accuracy and bonding strength of the bolt connection between the beam component 530 and the first wall 511, and thus improving the performance of the assembly device 5.

[0104] In some implementations, such as Figure 3 , Figure 5 and Figure 6 As shown, the assembly component 520 also includes a second detection component 550, which is used to detect the flatness between the beam component 530 and the first wall 511.

[0105] It should be understood that the second detection component 550 in this embodiment can be separately disposed in the first mounting area 521, or the second detection component 550 can be integrated inside the assembly component 520. That is, during the bolting process of the assembly component 520 connecting the first wall 511 and the beam component 530, the flatness between the beam component 530 and the first wall 511 during the bolting process, as well as the flatness after the bolting connection, can be detected. It should also be understood that the flatness in this embodiment refers to the distance between the first wall 511 and the beam component 530 along the direction of gravity.

[0106] In this embodiment of the application, by setting the assembly component 520 to also include a second detection component 550, the second detection component 550 is used to detect the flatness between the beam component 530 and the first wall 511, so as to improve the degree of connection between the beam component 530 and the first wall 511, reduce the shaking of the beam component 530 and the assembly platform 510 in subsequent vibration or impact tests, and improve the performance of the assembly component 520.

[0107] In some implementations, the maximum distance between the beam member 530 and the first surface 513 along the thickness direction of the first wall 511 is greater than or equal to 0 mm and less than or equal to 1 mm.

[0108] For example, along the thickness direction of the first wall 511, the maximum distance between the beam component 530 and the first surface 513 can be set to: 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., or its value is within the range obtained by any combination of the above two values.

[0109] In this embodiment, along the thickness direction of the first wall 511, the maximum distance between the beam component 530 and the first surface 513 is set to be greater than or equal to 0 mm and less than or equal to 1 mm, thereby further improving the bonding degree between the beam component 530 and the first wall 511, effectively reducing the shaking of the beam component 530 and the assembly platform 510 during subsequent vibration or impact tests, and improving the performance of the assembly component 520.

[0110] Figure 7 A partial structural schematic diagram of the assembly device 5 provided in another embodiment of this application is shown. Figure 8 A schematic diagram of the assembly device 5 provided in another embodiment of this application is shown. Figure 9 A cross-sectional schematic diagram of the assembly apparatus 5 provided in another embodiment of this application is shown.

[0111] In some implementations, the assembly device 5 further includes a transfer device 560 for moving the support component 570 of the battery device 10 to the first mounting area 521, such that the support component 570 is attached to the surface of the beam component 530 facing the first receiving cavity 512.

[0112] It should be understood that the transfer device 560 in this embodiment can be an automated guided vehicle (AGV) or a rail-guided vehicle. Exemplarily, when the transfer device 560 is configured as an AGV, it can move along a predetermined route to the first installation area 521. The transfer device 560 can move horizontally and also along the height of the assembly device 5. That is, the transfer device 560 can move the support member 570 horizontally to the first installation area 521, and upon reaching the first installation area 521, move it along the height of the assembly device 5, so that the support member 570 is attached to the surface of the beam member 530 facing the first receiving cavity 512. It should also be understood that the attachment of the support member 570 to the surface of the beam member 530 facing the first receiving cavity 512 means that a portion of the surface of the support member 570 facing the beam member 530 is in direct contact with the surface of the beam member 530 facing the first receiving cavity 512.

[0113] In this embodiment, by further providing a transfer device 560 in the assembly device 5, and the transfer device 560 being used to move the bracket component 570 of the battery device 10 to the first mounting area 521 so that the bracket component 570 is attached to the surface of the beam component 530 facing the first receiving cavity 512, the automation level of the assembly device 5 can be improved, thereby reducing labor costs and improving the performance of the assembly device 5.

[0114] In some implementations, such as Figure 8 and Figure 9 As shown, when the bracket component 570 is attached to the surface of the beam component 530 facing the first receiving cavity 512, the mounting component 520 is also used to bolt the bracket component 570 to the beam component 530.

[0115] In this embodiment, when the bracket component 570 is attached to the surface of the beam component 530 facing the first receiving cavity 512, the assembly component 520 is further configured to bolt the bracket component 570 to the beam component 530, so as to facilitate the installation and disassembly of the bracket component 570 and the beam component 530, thereby improving the performance of the assembly device 5.

[0116] In some implementations, such as Figures 4 to 7As shown, the beam component 530 also includes a second receiving cavity 534 and a third wall 533 connected to the second wall 531. The third wall 533 extends away from the first receiving cavity 512. The third wall 533 is provided with K third through holes 535 penetrating the third wall 533 along its thickness direction. The support component 570 includes a fourth wall 571 attached to the third wall 533. The fourth wall 571 is provided with L fourth through holes 572 penetrating the fourth wall 571 along its thickness direction. The beam component 530 and the support component 570 are bolted together through the third through holes 535 and the fourth through holes 572. On a plane perpendicular to the thickness direction of the third wall 533, the orthographic projections of the L fourth through holes 572 and the orthographic projections of the L third through holes 535 overlap each other. K is greater than L, and both K and L are positive integers greater than or equal to 2.

[0117] It should be understood that the second receiving cavity 534 in the embodiments of this application can be Figure 4 or Figure 6 The image shows a receiving cavity with openings at both ends along the direction of gravity.

[0118] It should also be understood that the shape of the third through hole 535 provided on the third wall 533 can be set according to actual needs. On a plane perpendicular to the thickness direction of the third wall 533, the shape of the third through hole 535 can be circular, elliptical, polygonal, rectangular, etc. It should also be understood that the number of third through holes 535 provided on each third wall 533 can be set according to actual needs; for example, the third wall 533 can be provided with one or more of the aforementioned third through holes 535. Correspondingly, the shape of the fourth through hole 572 provided on the fourth wall 571 can be set according to actual needs. On a plane perpendicular to the thickness direction of the fourth wall 571, the shape of the fourth through hole 572 can be circular, elliptical, polygonal, rectangular, etc. It should also be understood that the number of fourth through holes 572 provided on each fourth wall 571 can be set according to actual needs; for example, the fourth wall 571 can be provided with one or more of the aforementioned fourth through holes 572.

[0119] In this embodiment, the beam component 530 is further configured to include a second receiving cavity 534 and a third wall 533 connected to the second wall 531, wherein the third wall 533 extends in a direction away from the first receiving cavity 512, and the third wall 533 is provided with K third through holes 535 penetrating the third wall 533 along its thickness direction. The support component 570 includes a fourth wall 571 attached to the third wall 533, and the fourth wall 571 is provided with L fourth through holes 572 penetrating the fourth wall 571 along its thickness direction. The beam component 530 and the support component 570 are connected by the third through holes 535 and the fourth through holes 532. The through holes 572 are bolted together. On a plane perpendicular to the thickness direction of the third wall 533, the orthographic projections of the L fourth through holes 572 and the L third through holes 535 overlap, and K is greater than L. This allows the beam component 530 to be compatible with support components 570 of different sizes, thereby improving the product compatibility of the beam component 530. Furthermore, by providing K third through holes 535 on the third wall 533 of the beam component 530, the number of third through holes 535 is greater than the number of fourth through holes 572, which can reduce the weight of the beam component 530, making it easier to assemble the beam component 530 and reducing the weight of the assembly device 5, thereby improving the performance of the assembly device 5.

[0120] In some implementations, such as Figure 8 and Figure 9 As shown, the first detection component 540 is also used to detect the torque value between the beam component 530 and the bracket component 570 during the bolt connection process.

[0121] It should be understood that during the bolting process of the assembly component 520 to the beam component 530 and the bracket component 570, the first detection component 540 is able to detect the torque between the beam component 530 and the bracket component 570 during the bolting process.

[0122] It should be noted that the torque K2 during the bolt connection process between the beam component 530 and the support component 570 in this embodiment satisfies the following range: 0 N·m ≤ K2 ≤ 1000 N·m. For example, if the threshold torque for the bolt connection between the beam component 530 and the support component 570 is set to 1000 N·m, and the assembly component 520 detects a torque value reaching 1000 N·m during the bolt connection process between the beam component 530 and the support component 570, then the assembly component 520 stops assembling.

[0123] In this embodiment, the first detection component 540 is further configured to detect the torque value during the bolt connection process between the beam component 530 and the support component 570. That is, during the bolt connection process between the beam component 530 and the support component 570 by the assembly component 520, the first detection component 540 can detect the change in the torque value during the bolt connection process, so as to stop the bolt connection when the torque value reaches a preset threshold, thereby improving the accuracy and bonding strength of the bolt connection between the beam component 530 and the support component 570, and thus improving the performance of the assembly device 5.

[0124] In some implementations, such as Figure 8 and Figure 9 As shown, the second detection component 550 is also used to detect the flatness between the beam component 530 and the support component 570.

[0125] It should be understood that during the bolting process of the assembly component 520 to the beam component 530 and the support component 570, the flatness of the beam component 530 and the support component 570 during the bolting process, as well as the flatness after the bolting, can be detected. It should also be understood that the flatness in this embodiment refers to the distance between the beam component 530 and the support component 570 along the direction of gravity.

[0126] In this embodiment of the application, by further configuring the second detection component 550 to detect the flatness between the beam component 530 and the support component 570, the degree of connection between the beam component 530 and the support component 570 is improved, the shaking of the beam component 530 and the support component 570 during subsequent vibration or impact tests is reduced, thereby improving the performance of the assembly component 520.

[0127] In some implementations, the maximum distance between the support member 570 and the beam member 530 along the thickness direction of the first wall 511 is greater than or equal to 0 mm and less than or equal to 1 mm.

[0128] For example, along the thickness direction of the first wall 511, the maximum distance between the support component 570 and the beam component 530 can be set to: 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., or its value is within the range obtained by any combination of the above two values.

[0129] In this embodiment, along the thickness direction of the first wall 511, the maximum distance between the support component 570 and the beam component 530 is set to be greater than or equal to 0 mm and less than or equal to 1 mm, thereby further improving the bonding degree between the support component 570 and the beam component 530, effectively reducing the shaking of the support component 570 and the beam component 530 during subsequent vibration or impact tests, and improving the performance of the assembly component 520.

[0130] Figure 10 A schematic diagram of the assembly device 5 provided in another embodiment of this application is shown. Figure 11 A cross-sectional schematic diagram of the assembly apparatus 5 provided in another embodiment of this application is shown.

[0131] In some implementations, such as Figure 10 As shown, the transfer device 560 is also used to move the battery device 10 to the first mounting area 521 so that the battery device 10 is attached to the surface of the support member 570 facing the first receiving cavity 512.

[0132] It should be understood that when the transfer device 560 is configured as an automated guided vehicle, it can move along a predetermined route to the first mounting area 521. The transfer device 560 can move horizontally and also vertically along the assembly device 5. That is, the transfer device 560 can move the battery device 10 horizontally to the first mounting area 521, and upon reaching the first mounting area 521, move it vertically along the assembly device 5 so that the battery device 10 is attached to the surface of the support member 570 facing the first receiving cavity 512. It should also be understood that the battery device 10 being attached to the surface of the support member 570 facing the first receiving cavity 512 means that a portion of the surface of the battery device 10 facing the support member 570 is in direct contact with the surface of the support member 570 facing the first receiving cavity 512.

[0133] In this embodiment of the application, by further configuring the transfer device 560 to move the battery device 10 to the first mounting area 521, and such that the battery device 10 is attached to the surface of the bracket member 570 facing the first receiving cavity 512, the automation level of the assembly device 5 can be improved, thereby reducing labor costs and improving the performance of the assembly device 5.

[0134] In some implementations, such as Figure 10 and Figure 11 As shown, when the battery device 10 is attached to the surface of the bracket member 570 facing the first receiving cavity 512, the mounting member 520 is also used to bolt the battery device 10 to the bracket member 570.

[0135] It should be understood that the battery device 10 and the bracket component 570 can be bolted together using a T-bolt quick-change lock. That is, the T-bolt quick-change lock has a T-shaped screw. After the T-shaped screw is bolted together with the nut, the T-shaped nut at the end of the T-shaped screw away from the nut can engage with the rectangular through hole on the bracket. That is, the T-shaped screw can rotate a certain angle relative to the rectangular through hole so that the orthographic projection of the nut of the T-shaped screw overlaps with the orthographic projection of the rectangular through hole on a plane perpendicular to the height direction of the assembly device 5. This achieves a snap-fit ​​connection between the nut of the T-shaped screw and the rectangular through hole, thereby improving the bonding strength between the battery device 10 and the bracket component 570.

[0136] In this embodiment, when the battery device 10 is attached to the surface of the bracket member 570 facing the first receiving cavity 512, the assembly member 520 is configured to also bolt the battery device 10 to the bracket member 570, so as to facilitate the installation and removal between the bracket member 570 and the battery device 10, thereby improving the performance of the assembly device 5.

[0137] In some implementations, such as Figure 10 and Figure 11 As shown, the first detection component 540 is also used to detect the torque value between the battery device 10 and the bracket component 570 during the bolt connection process.

[0138] It should be understood that during the bolting process of the assembly component 520 connecting the battery device 10 and the bracket component 570, the first detection component 540 is able to detect the torque between the battery device 10 and the bracket component 570 during the bolting process.

[0139] It should be noted that the torque K3 during the bolt connection process between the battery device 10 and the bracket component 570 in this embodiment satisfies the following range: 0 N·m ≤ K3 ≤ 300 N·m. For example, if the threshold torque for the bolt connection between the battery device 10 and the bracket component 570 is set to 300 N·m, and the assembly component 520 detects a torque value reaching 1000 N·m during the bolt connection process between the battery device 10 and the bracket component 570, then the assembly component 520 stops assembling.

[0140] In this embodiment, the first detection component 540 is further configured to detect the torque value of the battery device 10 and the beam component 530 during the bolting process. That is, during the bolting process between the assembly component 520 and the battery device 10 and the bracket component 570, the first detection component 540 can detect the change in torque value during the bolting process, so as to stop the bolting when the torque value reaches a preset threshold. This improves the accuracy and bonding strength of the bolting between the battery device 10 and the bracket component 570, thereby improving the performance of the assembly device 5.

[0141] In some implementations, such as Figure 10 and Figure 11 As shown, the second detection component 550 is also used to detect the flatness between the battery device 10 and the bracket component 570.

[0142] It should be understood that during the bolting process of the assembly component 520 connecting the battery device 10 and the bracket component 570, the flatness of the battery device 10 and the bracket component 570 during the bolting process, as well as the flatness after the bolting, can be detected. It should also be understood that the flatness in this embodiment refers to the distance between the battery device 10 and the bracket component 570 along the direction of gravity.

[0143] In this embodiment of the application, by further configuring the second detection component 550 to detect the flatness between the battery device 10 and the bracket component 570, the degree of connection between the battery device 10 and the bracket component 570 is improved, the shaking of the battery device 10 and the bracket component 570 during subsequent vibration or impact tests is reduced, thereby improving the performance of the assembly component 520.

[0144] In some implementations, the maximum distance between the battery device 10 and the support member 570 along the thickness direction of the first wall 511 is greater than or equal to 0 mm and less than or equal to 1 mm.

[0145] For example, along the thickness direction of the first wall 511, the maximum distance between the battery device 10 and the bracket component 570 can be set to: 0mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, etc., or its value is within the range obtained by any combination of the above two values.

[0146] In this embodiment of the application, along the thickness direction of the first wall 511, the maximum distance between the battery device 10 and the bracket component 570 is set to be greater than or equal to 0 mm and less than or equal to 1 mm, so as to further improve the degree of connection between the bracket component 570 and the battery device 10, effectively reduce the shaking of the bracket component 570 and the battery device 10 during subsequent vibration or impact tests, and improve the performance of the assembly component 520.

[0147] In some implementations, after the assembly device 5 sequentially completes the threaded connections between the assembly platform 510 and the beam component 530, the support component 570 and the beam component 530, and the battery device 10 and the support component 570, the assembly platform 510 can be moved to the test area for subsequent vibration or impact testing. It should be noted that after the test is completed, the assembly platform 510 can be moved to the first installation area 521, and then the assembly device 5 can sequentially disassemble the above structures using the assembly component 520. The specific bolt disassembly process is similar to the bolt installation process described above. For example, the assembly component 520 can first disassemble the battery device 10 from the support component 570, then disassemble the support component 570 from the beam component 530, and finally disassemble the beam component 530 from the first wall 511 of the assembly platform 510.

[0148] According to some embodiments of this application, this application also provides an electrical device, including the assembly device 5 in any of the above embodiments, the assembly device 5 being used to assemble the battery device 10 onto the electrical device. Specifically, the electrical device can be the above... Figure 1 The vehicle 1 shown can also be any electrical device that uses the battery device 10.

[0149] According to some embodiments of this application, see Figures 3 to 6This application provides an assembly device 5, which includes an assembly platform 510 and an assembly component 520. The assembly platform 510 includes a first wall 511 and a first receiving cavity 512. The assembly component 520 is located in a first mounting area 521 and is used to bolt a beam component 530 corresponding to a battery device 10 to the first wall 511 in the first mounting area 521. The beam component 530 is attached to a first surface 513 of the first wall 511 away from the first receiving cavity 512. The first wall 511 is provided with a through-beam 530 extending along the thickness direction of the first wall 511. The first wall 511 has N first through holes 514. The beam component 530 includes a second wall 531 facing the first surface 513. The second wall 531 is provided with M second through holes 532 penetrating the second wall 531 along its thickness direction. The beam component 530 and the first wall 511 are bolted together through the first through holes 514 and the second through holes 532. On a plane perpendicular to the thickness direction of the first wall 511, the orthographic projections of the M second through holes 532 overlap with the orthographic projections of the M first through holes 514. N is greater than M, and both N and M are positive integers greater than or equal to 2. The assembly device 5 also includes a first detection component 540, which is used to detect the torque value between the beam component 530 and the first wall 511 during the bolting process. The assembly component 520 also includes a second detection component 550, which is used to detect the flatness between the beam component 530 and the first wall 511. Along the thickness direction of the first wall 511, the maximum distance between the beam component 530 and the first surface 513 is greater than or equal to 0 mm and less than or equal to 1 mm.
