[0002] The battery mounting system needs to meet certain requirements for stability. However, the current mounting system uses a simple connecting bracket structure. To ensure mounting stability, a large number of connecting brackets are required, resulting in a large number of vehicle parts and high costs. Summary of the Invention

[0003] In view of the above problems, the present application provides a battery device and an electrical device to reduce costs.

[0004] In the first aspect, an embodiment of the present application provides a battery device for connecting to a main body bracket of an electrical device, the battery device including a battery body and a connecting bracket; the battery body is provided with multiple mounting positions, and at least one mounting position is provided with multiple mounting holes; the connecting bracket is provided at the mounting position, for connecting the battery body and the main body bracket; the connecting bracket includes a first connecting component and a second connecting component connected to each other, and the second connecting component is used to connect to the main body bracket; at least one connecting bracket has multiple first connecting components, and the multiple first connecting components are connected to multiple mounting holes of the same mounting position in the battery body.

[0005] In the related art, generally only one first connecting component is provided in the same connecting bracket, that is, only one first connecting component is provided in the same mounting position of the battery body, while in the battery device provided in the embodiment of the present application, at least one connecting bracket has multiple first connecting components, and the multiple first connecting components are connected to multiple mounting holes of the same mounting position in the battery body. Compared with the related art, the same connecting bracket can have multiple connection points with the battery body, which can improve the connection stability between a single connecting bracket and the battery device to a certain extent. The same connecting bracket can have multiple connection points with the battery body. To make the mounting connection between the battery device and the main bracket of the electrical device stable, fewer connecting brackets can be used, which can reduce the number of components required for the battery device and the electrical device, and can reduce the production cost to a certain extent.

[0006] In some possible implementations, the connecting bracket also includes a buffer member; in the same connecting bracket, multiple first connecting components are spaced apart along the first direction, at least a portion of the second connecting component is spaced apart from the first connecting component, and at least can move relative to the first connecting component in the height direction of the first connecting component, at least a portion of the buffer member is connected between the multiple first connecting components, and at least a portion of the buffer member is connected between the second connecting component and the first connecting component, the buffer member can at least absorb at least part of the load in the height direction and the first direction, and the height direction is set at an angle to the first direction.

[0007] In the battery assembly provided in this embodiment, multiple first connecting assemblies are provided, and these multiple first connecting assemblies are connected by at least a portion of the buffer member. Simultaneously, at least a portion of the second connecting portion is connected to the first connecting assembly by at least a portion of the buffer member. The buffer member in the connecting bracket absorbs vibration loads in multiple directions, thereby reducing the risk of collision between the battery assembly and the main bracket. This allows the battery assembly to use fewer connecting brackets, meeting the vibration reduction requirements of the battery assembly mounting, and reducing manufacturing costs to a certain extent.

[0008] In some possible implementations, the first connecting component includes a main body and a first fastener. The main body is located on the side of the battery body close to the main body bracket. The main body is provided with a through hole. The through hole passes through two opposite sides of the main body in the height direction. A portion of the first fastener is passed through the through hole and connects the battery body and the main body. The buffer is arranged around at least part of the outer peripheral wall of the main body.

[0009] The first connecting component adopts the solution provided in this embodiment, including a main body and a first fastener. The main body and the battery body are connected by the first fastener, and the buffer component surrounds at least part of the outer wall of the main body. This can make the structure of the first connecting component simple, easy to install and disassemble, and easy to install the buffer component.

[0010] In some possible implementations, an outer peripheral wall of the main body is provided with a receiving groove, and at least a portion of the buffer member is disposed in the receiving groove.

[0011] The provision of the accommodating groove can, on the one hand, reduce the volume of the combined structure of the buffer and the first connecting component, and on the other hand, limit the relative position of at least part of the buffer and the first connecting component, thereby stabilizing the structure of the connecting bracket.

[0012] In some possible implementations, the main body includes a supporting portion and a first side portion, the supporting portion is provided with a through hole, the first side portion is connected to the outer peripheral wall of the supporting portion, and the first side portions are provided with two groups, the two groups of first side portions are spaced apart along the height direction, and the two groups of first side portions and the outer peripheral wall of the main body form a receiving groove.

[0013] The main body adopts the solution provided in this embodiment, which can make the main body structure simple, stable, and easy to prepare.

[0014] In some possible implementations, the two groups of first side portions are provided at both ends of the support portion in the height direction.

[0015] In this way, the volume of the accommodating groove can be larger, and a larger portion of the buffer component can be accommodated, thereby making the connection structure between the buffer component and the first connecting assembly stable.

[0016] In some possible implementations, the main body is an integrally formed part.

[0017] The main body is an integrally formed part, which has a stable structure and is easy to prepare.

[0018] In some possible implementations, at least a portion of the second connecting component is embedded in the buffer.

[0019] At least a portion of the second connecting component is embedded in the buffer component, which can stabilize the connection between the second connecting component and the buffer component.

[0020] In some possible implementations, the second connecting component includes a first connecting portion and a second connecting portion, the first connecting portion is connected to the buffer component, and the first connecting portion is arranged around at least a portion of the outer peripheral wall of the buffer component, and the second connecting portion connects the first connecting portion and the main bracket.

[0021] The second connecting component adopts the solution provided in this embodiment, which can make the structure of the second connecting component simple and the connection between the second connecting component and the first connecting component stable.

[0022] In some possible implementations, the first connecting portion and the first connecting component are connected.

[0023] The connection between the first connecting portion and the first connecting assembly can stabilize the structure of the connecting bracket.

[0024] In some possible implementations, the first connecting portion and the first connecting assembly form a receiving cavity having at least one opening, and at least a portion of the buffer component is disposed in the receiving cavity.

[0025] The first connecting portion and the first connecting assembly form a cavity that encloses at least a portion of the buffer member. This allows for a larger connection area between the first connecting portion and the first connecting assembly, as well as a larger contact area between the first connecting portion and the buffer member. This helps improve the structural stability of the connecting bracket and reduces the risk of the connecting bracket being crushed during use. Crushing risk refers to the critical state where a component experiences plastic deformation or structural failure under axial or radial loads.

[0026] In some possible implementations, the first connecting portion includes a surrounding portion and a second edge portion, the surrounding portion is arranged to surround at least a portion of the first connecting component and is spaced apart from the first connecting component, the second edge portion is located on a side of the surrounding portion close to the buffer component, and connects the bottom of the surrounding portion and the first connecting component, and the outer peripheral wall of the second edge portion, the surrounding portion and the first connecting component form a accommodating cavity.

[0027] The first connecting portion adopts the structure provided in this embodiment, which has a simple structure and can make the accommodating cavity larger, so that more buffer members can be arranged in the accommodating cavity, which helps to improve the stability of the connecting bracket structure.

[0028] In some possible implementations, a dimension of the surrounding portion in the height direction is greater than or equal to 1 / 2 of a dimension of the first connecting component in the height direction.

[0029] In this way, the accommodating cavity can be made larger, so that more buffer members can be arranged in the accommodating cavity, which helps to improve the stability of the connecting bracket structure.

[0030] In some possible implementations, the second side portion is connected to the bottom of the first connecting component.

[0031] In this way, except for the portion connected to the second edge portion, the outer peripheral walls of the other portions of the first connecting component can be used as the inner walls of the accommodating cavity, which can make the accommodating cavity larger and help improve the stability of the connecting bracket structure.

[0032] In some possible implementations, the second side portion connects multiple first connection components.

[0033] The second side portion is connected to a plurality of first connection components, which can reduce the risk of the portion where the buffer component is located being crushed, and further reduce the risk of the connection bracket being crushed during use.

[0034] In some possible implementations, the first connecting portion also includes a third side portion, which is located on the side of the surrounding portion away from the buffer component and is connected to the surrounding portion. The third side portion and the surrounding portion form a corner structure, and a portion of the second connecting portion is arranged in the space enclosed by the corner structure and is connected to both the third side portion and the surrounding portion.

[0035] The provision of the third side portion can increase the connection area between the second connection portion and the first connection portion, thereby stabilizing the structure of the second connection assembly.

[0036] In some possible implementations, the second connecting portion includes a straight portion and a bent portion, the bent portion is connected to the first connecting portion, the straight portion is connected to the bent portion, and the straight portion is used to fit and connect with the main support.

[0037] Since the part of the main bracket that is used to contact the second connecting part is generally flat, the second connecting part includes a straight part and a bent part. The straight part is attached to and connected to the main bracket, which facilitates the stable connection between the second connecting part and the main bracket, and the position of the straight part can be set according to installation needs, which helps to adapt to different usage environments.

[0038] In some possible implementations, the second connecting assembly further includes a second fastener, and the second fastener is used to connect the second connecting portion and the main support.

[0039] The second connecting portion is connected to the main body bracket through a second fastener, which facilitates the connection and disassembly of the connecting bracket and the main body bracket and facilitates the replacement of the connecting bracket.

[0040] In some possible implementations, a plurality of second connection portions are provided, and the plurality of second connection portions are spaced apart along the outer peripheral wall of the first connection portion.

[0041] By adopting the solution provided in this embodiment, multiple connection points can be provided between the second connection component and the main frame, so that the connection between the connection frame and the main frame is stable, and the mounting stability of the battery device can be improved.

[0042] In some possible implementations, two second connection portions are provided, and the two second connection portions are provided on both sides of the first connection portion along the first direction.

[0043] By adopting the solution provided in this embodiment, the structure of the second connecting component can be simplified, and there are multiple connection points between the second connecting component and the main bracket, so that the connection between the connecting bracket and the main bracket is stable, and the mounting stability of the battery device can be better.

[0044] In some possible implementations, the first connection portion and the second connection portion are integrally formed.

[0045] The first connecting portion and the second connecting portion are integrally formed, which is convenient for preparation and has a stable structure.

[0046] In some possible implementations, the second connecting assembly further includes a third connecting portion, which is connected to the second connecting portion and is used to connect to the main support.

[0047] The third connecting portion is provided when the distance between the main support and the battery body is large, and the connection between the main support and the combined structure of the first connecting assembly and the buffer member cannot be achieved through the first connecting portion and the second connecting portion.

[0048] In some possible implementations, the buffer component is integrally connected to the first connecting component and the second connecting component by injection molding.

[0049] By adopting the solution provided in this embodiment, the buffer component can be tightly connected to the first connecting component and the second connecting component, so that the structure of the connecting bracket is stable.

[0050] In some possible implementations, at least a portion of the buffer component is an elastic portion.

[0051] By adopting the solution provided in this embodiment, at least a portion of the buffer component can be made elastic. The damping characteristics of the elastic portion can absorb high-frequency vibrations to which the electrical device is subjected during use, such as high-frequency vibrations (50-1000Hz) generated by the motor / road surface, reducing the vibration energy transmitted to the battery device by more than 60%, thereby reducing the risk of micro-damage to the internal structure of the battery device; by adjusting the stiffness of the elastic portion (usually designed to be in the range of 20-50N / mm), the natural frequency of the battery device system is made to avoid the main excitation frequency of the main part of the electrical device (such as the motor fundamental frequency of 20-200Hz), thereby preventing fatigue fracture caused by resonance.

[0052] In some possible implementations, the buffer component is an integrally formed component.

[0053] The buffer component is an integrally formed component, which can make the buffer component structure stable and easy to prepare.

[0054] In some possible implementations, the buffer member is a rubber member.

[0055] The buffer is made of rubber, which can make the buffer have excellent shock absorption and cushioning performance, can adapt to complex environments, and has low production costs. It can be made into complex shapes through molding, extrusion and other processes. The density is lower than that of metal, and it is suitable for weight-sensitive applications.

[0056] In some possible implementations, the first direction is perpendicular to the height direction.

[0057] This makes design and processing easier.

[0058] In a second aspect, an embodiment of the present application provides an electrical device, comprising a main frame and a battery device provided by any of the above solutions, wherein the connecting frame is connected to the main frame.

[0090] Unless otherwise specified, all embodiments and optional embodiments of the present application can be combined with each other to form a new technical solution.

[0091] With the rapid development of new energy vehicles such as electric and hybrid vehicles, battery devices, as a crucial component of these devices, are facing significantly higher safety, reliability, and performance requirements. For example, modern vehicles are increasingly integrating technologies such as intelligent driving and connected vehicles, which place higher demands on the accuracy and reliability of vehicle control systems. To improve energy efficiency and range, vehicle designs are trending towards lightweight design, which places higher demands on the strength and durability of industrial control systems. As vehicle industrial control requirements become increasingly stringent, battery mounting systems must meet higher performance standards (such as longer lifespan, enhanced safety, and improved stability). These systems must be able to cope with a wider range of more extreme operating conditions, i.e., meet these standards under more uncertain environments or factors. To meet these requirements, systems must be more adaptable to address the challenges posed by uncertainty. Current mounting systems use simple connecting brackets. To ensure mounting stability, a large number of these brackets are required, resulting in a large number of vehicle components and high costs.

[0092] To at least partially alleviate the aforementioned issues, embodiments of the present application provide a battery device. In this battery device, at least one connecting bracket has multiple first connecting assemblies, and the multiple first connecting assemblies connect to multiple mounting holes at the same mounting position in the battery body. Compared to related art, this allows the same connecting bracket to have multiple connection points with the battery body, which can improve the connection stability between a single connecting bracket and the battery device to a certain extent. As a result, the battery device can use fewer connecting brackets to meet the mounting requirements of the battery device, which can reduce the number of components required for the battery device and the electrical device using the battery device, thereby reducing manufacturing costs.

[0093] The electrical devices disclosed in the embodiments of the present application may be, but are not limited to, electric toys, electric tools, battery vehicles, electric cars, ships, spacecraft, etc. The electric toys may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. The spacecraft may include airplanes, rockets, space shuttles, and spacecraft, etc.

[0094] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0095] Please refer to Figure 1 , Figure 1A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. A battery device (Battery Apparatus) is provided inside the vehicle 1000. The battery device 100 may be provided at the bottom, head, or tail of the vehicle 1000. The battery device 100 may be used to power the vehicle 1000. For example, the battery device 100 may serve as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to power the motor 300, for example, to meet the power requirements for starting, navigating, and driving the vehicle 1000.

[0096] In some embodiments of the present application, the battery device 100 can serve not only as an operating power source for the vehicle 1000 , but also 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 .

[0097] Please refer to Figure 2 , Figure 2 The battery device 100 provided in some embodiments of the present application is a schematic diagram of an exploded structure. The battery device 100 includes a housing 10 and a battery cell 20 , wherein the battery cell 20 is accommodated in the housing 10 .

[0098] The housing 10 is used to provide storage space for the battery cells 20 and can have various structures. In some embodiments, the housing 10 may include a cover 11 and a tray 12. The cover 11 covers the tray and, together with the tray 12, defines a storage space for the battery cells 20. The tray 12 may be a hollow structure with one end open, and the cover 11 may be a plate-like structure. The cover 11 covers the open side of the tray 12, so that the cover 11 and tray 12 together define a storage space. Alternatively, both the cover 11 and tray 12 may be hollow structures with side openings, with the open side of the cover 11 covering the open side of the tray 12. Of course, the housing 10 formed by the cover 11 and tray 12 can have various shapes, such as a circular through-hole or a rectangular parallelepiped. The tray 12 is a critical structural component in the battery system, used to store and protect the battery cells. It also significantly impacts the collision safety of the vehicle and the torsional and bending stiffness of the vehicle body.

[0099] Multiple battery cells 20 may be provided, connected in series, parallel, or in a hybrid manner via a busbar assembly. A hybrid arrangement refers to a combination of series and parallel connections among the multiple battery cells 20. Multiple battery cells 20 may be directly connected in series, parallel, or in a hybrid arrangement, and the entire assembly of multiple battery cells 20 may then be housed within the housing 10. Alternatively, the battery assembly 100 may comprise a battery module in which multiple battery cells 20 are first connected in series, parallel, or in a hybrid arrangement, and then the multiple battery modules are further connected in series, parallel, or in a hybrid arrangement to form a single assembly and housed within the housing 10. The battery assembly 100 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells 20. For example, the multiple battery cells 20 may form a battery module, which is a single module formed by arranging and securing the multiple battery cells 20. For example, the battery module may be formed by binding the multiple battery cells 20 together using cable ties.

[0100] Each battery cell 20 can be a secondary battery or a primary battery. A secondary battery refers to a battery cell that can be recharged to activate its active material after discharge, allowing continued use. The battery cell 20 can be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, a lead-acid battery, or the like, though this embodiment of the present application does not limit this. The battery cell can have a round through-hole, a flat body, a rectangular parallelepiped, or other shapes.

[0105] The main frame 400 is the primary structural component in an electrical device, supporting and securing core components (such as the battery unit 100, engine, and motor). It provides a stable mounting base, ensuring safe and reliable operation of the core components while also withstanding various external forces (such as vibration, impact, and gravity).

[0106] The main frame 400 can be composed of one or more components, depending on the type of electrical device and its intended use. For example, if the electrical device is a vehicle, the main frame 400 can serve as at least a portion of the vehicle's chassis structure, such as at least a portion of the vehicle's floor, and can be a crossbeam or longitudinal beam. If the electrical device is a ship, the main frame 400 can serve as the hull and be composed of multiple components.

[0107] The main frame 400 is generally a three-dimensional structure having a certain length direction, a width direction and a height direction Z. The height direction Z refers to a direction perpendicular to the ground or a reference plane.

[0108] The battery body 100a, which includes the aforementioned housing and battery cells, is the primary portion of the battery assembly 100 and the entire component of the battery assembly 100, excluding the connecting bracket 500. The sides of the battery body 100a are generally provided with multiple mounting locations 100b. These locations 100b are areas or structures on the battery body used for mounting, securing, or connecting the connecting bracket 500. Mounting holes are through-holes provided in the mounting locations 100b for fasteners such as bolts and screws in the connecting bracket 500 to pass through. The connection between the connecting bracket 500 and the mounting holes can be achieved through-hole, threaded, or snap-on connections, depending on the intended use.

[0109] The connecting bracket 500 is a connecting component that connects the battery body 100a and the main body bracket 400. In this embodiment, a plurality of connecting brackets 500 are provided, and the structures of the plurality of connecting brackets 500 can be the same or different, depending on the specific use requirements.

[0110] The connecting bracket 500 includes a first connecting component 51 and a second connecting component 52 connected to each other. The second connecting component 52 is used to connect to the main bracket 400.

[0111] At least one connecting bracket 500 has multiple first connecting components 51, and the multiple first connecting components 51 are connected to multiple mounting holes of the same mounting position 100b in the battery main body 100a, which means that at least one connecting bracket 500 can include only the first connecting component 51, or can also include other components in addition to the first connecting component 51, such as a second connecting component, a third connecting component, etc., as long as these components work together to ensure that the connecting bracket 500 can firmly fix the battery main body 100a on the main bracket 400, and in the connecting bracket 500 with multiple first connecting components 51, the multiple first connecting components 51 are respectively connected to the multiple mounting holes of the same mounting position 100b in the battery main body 100a.

[0112] The first connecting component 51 is a fixing component in the connecting bracket 500 connected to the battery body 100a, and its function is to firmly install the connecting bracket 500 on the battery body 100a to ensure a stable and reliable connection between the connecting bracket 500 and the battery body 100a.

[0113] The first connecting assembly 51 may be composed of one or more parts, and the specific structure may be determined according to the use requirements. For example, the first connecting assembly 51 may include at least part of bolts, nuts, buckles, etc., and may also include at least part of welding points, washers, positioning pins, etc.

[0114] The second connecting assembly 52 is a fixing component of the connecting bracket 500 that is connected to the main bracket 400. Its function is to firmly mount the connecting bracket 500 on the main bracket 400 and ensure a stable and reliable connection between the connecting bracket 500 and the main bracket 400. The specific structure of the second connecting assembly 52 can be determined according to the actual use requirements, and may include, for example, bolts, nuts, and at least some of welds, washers, and locating pins.

[0115] The structure of the second connecting component 52 may be the same as or different from that of the first connecting component 51 , depending on the specific usage requirements.

[0116] In this embodiment, the first connecting component 51 and the second connecting component 52 can be directly connected or indirectly connected. Indirect connection means that the first connecting component 51 and the second connecting component 52 are spaced apart and connected through other components.

[0117] In the related art, only one first connecting component 51 is generally provided in the same connecting bracket 500, that is, only one first connecting component 51 is provided in the same mounting position 100b of the battery body 100a. However, in the battery device provided in the embodiment of the present application, at least one connecting bracket 500 has multiple first connecting components 51, and the multiple first connecting components 51 are connected to multiple mounting holes in the same mounting position 100b of the battery body 100a. Compared with the related art, the same connecting bracket 500 can have multiple connection points with the battery body 100a, which can improve the connection stability between a single connecting bracket and the battery device to a certain extent. To ensure a stable mounting connection between the battery device and the main bracket of the electrical device, fewer connecting brackets 500 can be used, which can reduce the number of components required for the battery device and the electrical device, and can reduce the manufacturing cost to a certain extent.

[0118] Please refer to Figures 4 to 6 , Figure 5 for Figure 4 The side view of the connecting bracket is shown in FIG. Figure 6 For the Figure 5 In the cross-sectional structural diagram along line AA, in some embodiments, the connecting bracket 500 further includes a buffer member 53 .

[0119] In the same connecting bracket 500, multiple first connecting assemblies 51 are spaced apart along the first direction X. At least a portion of the second connecting assembly 52 is spaced apart from the first connecting assembly 51 and is at least movable relative to the first connecting assembly 51 in the height direction of the first connecting assembly 51. At least a portion of the buffer 53 is connected between the multiple first connecting assemblies 51, and at least a portion of the buffer 53 is connected between the second connecting assembly 52 and the first connecting assembly 51. The buffer 53 is capable of absorbing at least a portion of the load in the height direction Z and the first direction X. The height direction Z is arranged at an angle to the first direction X.

[0120] The first direction X is the arrangement direction of the plurality of first connecting components 51 , which is generally the length direction of the battery body 100 a , and may also be the width direction of the battery body 100 a , or other directions, depending on specific usage requirements.

[0121] In this embodiment, at least a portion of the second connecting assembly 52 is spaced apart from the first connecting assembly 51. This means that the second connecting assembly 52 can be spaced apart from the first connecting assembly 51 in its entirety, or a portion can be movably connected to the first connecting assembly 51, while another portion can be spaced apart from the first connecting assembly 51. At least a portion of the second connecting assembly 52 can be spaced apart from the first connecting assembly 51 only in the first direction X, or can be spaced apart not only in the first direction X but also in other directions (such as a second direction Y). The second direction Y is perpendicular to both the height direction Z and the first direction X.

[0122] The above-mentioned ability to move relative to the first connecting component 51 in the height direction Z of the first connecting component 51 means that when the second connecting component 52 is subjected to external force, it can at least move relative to the first connecting component 51 along the height direction Z. In addition, according to usage needs, it can also move relative to the first connecting component 51 along the first direction X or other directions (such as the second direction Y).

[0123] The buffer member 53 is part of the connecting bracket 500 and is located on the force transmission path between the main bracket 400 and the battery body 100a. It is used to support and connect the first connecting component 51 and the second connecting component 52. Its function is to provide structural support and transfer load to ensure the relative position and stability between the first connecting component 51 and the second connecting component 52.

[0124] In this embodiment, the buffer member 53 can buffer forces in multiple directions. The buffer member 53 can absorb the load between the multiple first connecting components 51 and the load between the first connecting component 51 and the second connecting component 52. The above loads include but are not limited to loads in the first direction X and the height direction Z.

[0125] In this embodiment, the first connecting component 51 of the connecting bracket 500 is connected to the main bracket 400, the second connecting component 52 is connected to the battery body 100a, and the buffer 53 serves as an intermediate structure to support and transfer loads. This design ensures that the battery body 100a is firmly mounted on the main bracket 400 while withstanding vibration, impact, and other dynamic loads during use of the electrical device.

[0126] There are multiple first connecting components 51, and the multiple first connecting components 51 are connected by a buffer 53. In this way, when at least one first connecting component 51 is subjected to an external force and is relatively displaced with other first connecting components 51 in the first direction X or other directions, the buffer 53 can absorb at least part of the load transmitted by the first connecting component 51, thereby reducing the risk of collision between the battery body 100a and the main frame 400.

[0127] At least a portion of the second connecting component 52 is spaced apart from the first connecting component 51, and the two are connected by a buffer member 53. In this way, when the first connecting component 51 is subjected to external force and undergoes relative displacement with the second connecting component 52 in the first direction X, the height direction Z or other directions, the buffer member 53 can absorb at least part of the load, thereby reducing the risk of collision between the battery body 100a and the main bracket 400.

[0128] Thus, the battery device provided in this embodiment has multiple first connecting assemblies 51, and these multiple first connecting assemblies 51 are connected by at least a portion of the buffer 53. At the same time, at least a portion of the second connecting assembly 52 is connected to the first connecting assembly 51 by at least a portion of the buffer 53. The buffer 53 in the connecting bracket 500 can absorb vibration loads in multiple directions, thereby reducing the risk of collision between the battery body 100a and the main bracket 400. This allows the battery device to use fewer connecting brackets 500, meeting the shock absorption requirements of the battery body 100a, and reducing manufacturing costs to a certain extent.

[0129] Among them, there are multiple first connecting components 51, which not only helps to absorb loads in multiple directions, but also can improve the mounting capacity of the battery body 100a to a certain extent compared to setting only one first connecting component 51, so that the structure of the electrical device using the battery device is stable.

[0130] like Figures 4 to 6 As shown, in some embodiments, the first connecting assembly 51 includes a main body 511 and a first fastener 512. The main body 511 is located on a side of the battery body 100a close to the main bracket 400. The main body 511 is provided with a through hole 511a. The through hole 511a extends through two opposite sides of the main body 511 in the height direction Z. A portion of the first fastener 512 is disposed within the through hole 511a and connects the battery body 100a and the main body 511. The buffer member 53 is disposed around at least a portion of the outer peripheral wall of the main body 511.

[0131] The main body 511 is the main part of the first connecting component 51 and plays a supporting role. The main body 511 can be composed of one or more parts, which can be determined according to the specific use requirements.

[0132] The main body 511 is located between the battery body 100a and the main frame 400. This means that the main body 511, as a solid component, can be surrounded or clamped from both sides by the battery body 100a and the main frame 400. It can also be spaced apart from at least one of the battery body 100a and the main frame 400, depending on the specific needs. In this embodiment, the main body 511 is fastened to the battery body 100a via a first fastener 512. The main body 511 and the main frame 400 may or may not be spaced apart, depending on the specific needs.

[0133] The first fastener 512 is used to provide a mechanical locking force to fix the main body 511 and the battery body 100a together. The first fastener 512 can include a bolt, a nut, a screw, etc., and the specific method can be determined according to the actual use requirements.

[0134] The buffer member 53 is disposed around at least a portion of the outer peripheral wall of the main body 511, meaning that the buffer member 53 at least partially surrounds the outer peripheral wall of the main body 511. This "at least partially surrounding" includes at least the following scenarios: first, surrounding only at least a portion of the outer peripheral wall of the main body 511; second, surrounding the entire outer peripheral wall of the main body 511. The outer peripheral wall refers to the circumferential wall surface of an object, i.e., the side or outer surface surrounding the outer circumference of the object and extending in its circumferential direction (circumferential direction).

[0135] The first connecting component 51 adopts the solution provided in this embodiment, including a main body 511 and a first fastener 512. The main body 511 and the battery body 100a are connected by the first fastener 512, and the buffer 53 surrounds at least part of the outer wall of the main body 511. This can make the structure of the first connecting component 51 simple, easy to install and disassemble, and easy to install the buffer 53.

[0136] like Figure 6 As shown, in some embodiments, the outer peripheral wall of the main body 511 is provided with a receiving groove 513 . At least a portion of the buffer member 53 is disposed in the receiving groove 513 .

[0137] The receiving groove 513 is a groove structure for receiving at least part of the buffer member 53, and can be an annular groove, an arc groove, a strip groove, etc. according to the use requirements. The receiving groove 513 can include one or more groove structures according to the use requirements.

[0138] At least part of the buffer 53 is disposed in the receiving groove 513 , which includes the following situations: first, the buffer 53 is entirely located in the receiving groove 513 ; second, part of the buffer 53 is located in the receiving groove 513 , and the other part is located outside the receiving groove 513 .

[0139] The setting of the accommodating groove 513 can, on the one hand, reduce the volume of the combined structure of the buffer 53 and the first connecting component 51, and on the other hand, limit the relative position of at least part of the buffer 53 and the first connecting component 51, so that the structure of the connecting bracket 500 is stable.

[0140] In some embodiments, the main body 511 includes a support portion 5111 and a first side portion 5112. The support portion 5111 is provided with a through hole 511a. The first side portion 5112 is connected to the outer peripheral wall of the support portion 5111. Two groups of first side portions 5112 are provided. The two groups of first side portions 5112 are spaced apart along the height direction Z. The two groups of first side portions 5112 and the outer peripheral wall of the main body 511 form a receiving groove 513.

[0141] The support portion 5111 is the main structure and support structure of the main body 511. The support portion 5111 can be composed of one or more parts, which can be determined according to the specific needs of use.

[0142] The first side portion 5112 is a component located outside the support portion 5111 and connected to the outer peripheral wall of the support portion 5111. It can be composed of one or more parts and can be integrally formed with the support portion 5111, or connected by welding, plugging, etc.

[0143] Each group of first side portions 5112 may include one or more first side portions 5112 according to usage requirements.

[0144] The main body 511 adopts the solution provided in this embodiment, which can make the main body 511 simple and stable in structure and easy to prepare.

[0145] In some embodiments, the two groups of first side portions 5112 are respectively disposed at two ends of the support portion 5111 in the height direction Z.

[0146] In this way, the volume of the accommodating groove 513 can be larger, and a larger portion of the buffer member 53 can be accommodated, thereby making the connection structure between the buffer member 53 and the first connecting assembly 51 stable.

[0147] In some embodiments, the main body 511 is an integrally formed part.

[0148] The integrally formed portion refers to a buffer 53 that is processed into a complete form at one time through an integral forming process, avoiding assembly or splicing to improve strength, aesthetics or production efficiency. The integral forming process can be injection molding, 3D printing, etc., and the specific process can be determined according to the use requirements.

[0149] The main body 511 is an integrally formed part, which has a stable structure and is easy to prepare.

[0150] like Figure 6 As shown, in some embodiments, at least a portion of the second connecting component 52 is embedded in the buffer member 53 .

[0151] Insertion refers to a core assembly process in which at least a portion of the second connecting component 52 is permanently or semi-permanently embedded in a predetermined cavity of the buffer component 53 through mechanical interference or deformation fit. This deformation fit can be at least one of an interference fit (press fit), a transition fit (cold fit / shrink fit), and an elastic deformation fit.

[0152] At least a portion of the second connecting component 52 is embedded in the buffer component 53 , which can stabilize the connection between the second connecting component 52 and the buffer component 53 .

[0153] like Figures 3 to 6As shown, in some embodiments, the second connecting assembly 52 includes a first connecting portion 521 and a second connecting portion 522. The first connecting portion 521 is connected to the buffer member 53 and surrounds at least a portion of the outer peripheral wall of the buffer member 53. The second connecting portion 522 connects the first connecting portion 521 and the main frame 400.

[0154] The first connection portion 521 and the second connection portion 522 are both part of the second connection assembly 52 . The materials of the two portions can be the same or different. The two portions can be integrally formed or connected by welding, plugging, or the like.

[0155] The first connection part 521 and the second connection part 522 may be provided in one or more pieces, and may be respectively composed of one or more parts.

[0156] The first connecting portion 521 may be an arc-shaped portion or an annular portion, and the specific shape may be determined according to usage requirements.

[0157] The second connection portion 522 can be in a bent shape or a straight plate structure according to usage requirements, and the specific shape can be determined according to usage requirements.

[0158] The second connecting component 52 adopts the solution provided in this embodiment, which can make the structure of the second connecting component 52 simple and the connection between the second connecting component 52 and the first connecting component 51 stable.

[0159] In some embodiments, the first connecting portion 521 is connected to the first connecting component 51 .

[0160] The first connecting portion 521 and the first connecting assembly 51 can be connected by welding, integral molding, etc., and the specific method can be determined according to usage requirements.

[0161] The connection between the first connecting portion 521 and the first connecting assembly 51 can stabilize the structure of the connecting bracket 500 .

[0162] In some embodiments, the first connecting portion 521 and the first connecting assembly 51 form a receiving cavity having at least one opening, and at least a portion of the buffer member 53 is disposed in the receiving cavity.

[0163] The accommodating cavity may be provided with one or more openings, which may be determined according to the specific use requirements.

[0164] During preparation, the first connection portion 521 and the first connection assembly 51 may be connected and formed first, and then the buffer component 53 may be inserted into the accommodating cavity through the opening or prepared by injection molding.

[0165] The first connecting portion 521 and the first connecting assembly 51 form a cavity that encloses at least a portion of the buffer 53. This increases the connection area between the first connecting portion 521 and the first connecting assembly 51, and the contact area between the first connecting portion 521 and the buffer 53. This helps improve the structural stability of the connecting bracket 500 and reduces the risk of crushing of the connecting bracket 500 during use. Crushing risk refers to the critical state where a component undergoes plastic deformation or structural failure under axial or radial loads.

[0166] like Figures 7 to 9 As shown, Figure 7 Schematic diagram of the three-dimensional structure of the connecting bracket in the battery device provided in other embodiments of the present application, Figure 8 for Figure 7 The side view of the connecting bracket is shown in FIG. Figure 9 For the Figure 8 In a cross-sectional view taken along line BB, in some embodiments, the first connecting portion 521 includes a surrounding portion 5211 and a second side portion 5212. The surrounding portion 5211 surrounds at least a portion of the first connecting component 51 and is spaced apart from the first connecting component 51. The second side portion 5212 is located on a side of the surrounding portion 5211 proximal to the buffer 53 and connects the bottom of the surrounding portion 5211 to the first connecting component 51. The second side portion 5212, the surrounding portion 5211, and the outer peripheral wall of the first connecting component 51 define a receiving cavity.

[0167] The surrounding portion 5211 and the second side portion 5212 are both components of the first connecting portion 521. The first connecting portion 521 may include only the surrounding portion 5211 and the second side portion 5212, or may include other parts in addition to the surrounding portion 5211 and the second side portion 5212, depending on the specific usage requirements.

[0168] The surrounding portion 5211 is the portion of the first connecting portion 521 that contacts the buffer member 53 , and may be an arc-shaped structure or a ring-shaped structure, depending on the specific needs of use.

[0169] The second side portion 5212 is located outside the surrounding portion 5211 and is connected to the outer wall of the surrounding portion 5211. At least a portion of the second side portion 5212 radially protrudes from the surrounding portion 5211. The second side portion 5212 can be a plate or a block, depending on the specific application requirements.

[0170] The accommodating cavity is located above the second side portion 5212 , that is, the buffer member 53 is provided above the second side portion 5212 in the height direction Z.

[0171] The first connecting portion 521 adopts the structure provided in this embodiment, which has a simple structure and can make the accommodating cavity larger, so that more buffer members 53 can be arranged in the accommodating cavity, which helps to improve the stability of the connecting bracket 500 structure.

[0172] like Figures 9 to 12 As shown, Figure 10 Schematic diagram of the three-dimensional structure of the connecting bracket in the battery device provided in other embodiments of the present application, Figure 11 for Figure 10 The side view of the connecting bracket is shown in FIG. Figure 12 For the Figure 11 Schematic diagram of the cross-sectional structure along the CC line. In some embodiments, the size of the surrounding portion 5211 in the height direction Z is greater than or equal to 1 / 2 of the size of the first connecting component 51 in the height direction Z.

[0173] In this way, the accommodating cavity can be made larger, so that more buffer members 53 can be arranged in the accommodating cavity, which helps to improve the stability of the connecting bracket 500 structure.

[0174] In some embodiments, the second side portion 5212 is connected to the bottom of the first connecting component 51 .

[0175] In this way, except for the portion connected to the second side portion 5212 , the outer peripheral walls of the other portions of the first connecting component 51 can be used as the inner walls of the accommodating cavity, which can make the accommodating cavity larger and help improve the stability of the connecting bracket 500 structure.

[0176] In some embodiments, the second side portion 5212 connects a plurality of first connection components 51 .

[0177] The second edge portion 5212 can be connected to the first connecting component 51 by welding, plugging or other means.

[0178] The second side portion 5212 is connected to the plurality of first connection components 51 , which can reduce the risk of the portion where the buffer member 53 is located being crushed, thereby further reducing the risk of the connection bracket 500 being crushed during use.

[0179] like Figure 9 and Figure 12 As shown, in some embodiments, the first connecting portion 521 further includes a third side portion 5213. The third side portion 5213 is located on a side of the surrounding portion 5211 facing away from the buffer member 53 and is connected to the surrounding portion 5211. The third side portion 5213 and the surrounding portion 5211 form a corner structure. A portion of the second connecting portion 522 is disposed within the space enclosed by the corner structure and is connected to both the third side portion 5213 and the surrounding portion 5211.

[0180] The third side portion 5213 is a component of the first connecting portion 521 and may be a plate, a block, etc., and its extending direction is perpendicular to the height direction Z or is arranged at an acute angle or an obtuse angle.

[0181] The corner structure refers to an angular connection formed by a specific geometric fit between the third side portion 5213 and the surrounding portion 5211. The specific geometric fit may be that the third side portion 5213 and the surrounding portion 5211 extend in different directions, and the angle between the two connected surfaces is less than 180°.

[0182] A portion of the second connection portion 522 is disposed in the space surrounded by the corner structure, which means that a portion of the second connection portion 522 is covered by the corner structure.

[0183] The second connection portion 522 can be welded to the third side portion 5213 and the surrounding portion 5211, or connected by other means (such as gluing, plugging, etc.).

[0184] The provision of the third side portion 5213 can increase the connection area between the second connection portion 522 and the first connection portion 521 , thereby stabilizing the structure of the second connection component 52 .

[0185] like Figure 12 As shown, in some embodiments, the second connecting portion 522 includes a straight portion 5221 and a bent portion 5222. The bent portion 5222 is connected to the first connecting portion 521. The straight portion 5221 is connected to the bent portion 5222, and the straight portion 5221 is used to fit and connect with the main support 400.

[0186] The straight portion 5221 and the bent portion 5222 are both components of the second connecting portion 522. The second connecting portion 522 may include only the straight portion 5221 and the bent portion 5222, or may include other structures in addition to the straight portion 5221 and the bent portion 5222.

[0187] The straight portion 5221 is a portion of the component extending generally in a straight line in its longitudinal direction. The surface of the straight portion 5221 in contact with the main support 400 is a continuous plane with a curvature radius greater than 1000 mm. The curvature radius of at least part of the bent portion 5222 is ≤ 10 mm.

[0188] Since the portion of the main bracket 400 that contacts the second connecting portion 522 is generally flat, the second connecting portion 522 includes a straight portion 5221 and a bent portion 5222. The straight portion 5221 is attached to and connected to the main bracket 400, which facilitates stable connection between the second connecting portion 522 and the main bracket 400, and allows the position of the straight portion 5221 to be set according to installation needs, which helps to adapt to different usage environments.

[0189] like Figure 6As shown, in some embodiments, the second connecting assembly 52 further includes a second fastener 523. The second fastener 523 is used to connect the second connecting portion 522 and the main support 400.

[0190] The structure of the second fastener 523 may be the same as or different from that of the first fastener 512 , depending on the specific usage requirements.

[0191] The second connecting portion 522 is connected to the main frame 400 via a second fastener 523 , which facilitates connection and disassembly of the connecting frame 500 and the main frame 400 and facilitates replacement of the connecting frame 500 .

[0192] like Figure 6 As shown, in some embodiments, a plurality of second connection portions 522 are provided, and the plurality of second connection portions 522 are spaced apart along the outer peripheral wall of the first connection portion 521 .

[0193] Multiple second connection parts 522 are arranged at intervals along the outer peripheral wall of the first connection part 521, which means that the arrangement path of the second connection parts 522 follows the contour of the outer ring side surface of the first connection part 521 (such as a cylindrical surface, a polygonal side surface, etc.), and a gap is left between two adjacent second connection parts 522.

[0194] By adopting the solution provided in this embodiment, multiple connection points can be provided between the second connecting component 52 and the main bracket 400, so that the connection between the connecting bracket 500 and the main bracket 400 is stable, and the mounting stability of the battery body 100a is better.

[0195] like Figure 6 As shown, in some embodiments, there are two second connection parts 522. The two second connection parts 522 are respectively arranged on both sides of the first connection part 521 along the first direction X.

[0196] The two second connection portions 522 are provided on both sides of the first connection portion 521 along the first direction X, which means that the two second connection portions 522 are provided on both sides of the first connection portion 521, and the two second connection portions 522 are respectively spaced apart from the first connection portion 521 in the first direction X. The spacing between the two second connection portions 522 and the first connection portion 521 can be the same or different, depending on the specific needs.

[0197] By adopting the solution provided in this embodiment, the structure of the second connecting component 52 can be simplified, and there are multiple connection points between the second connecting component 52 and the main bracket 400, so that the connection between the connecting bracket 500 and the main bracket 400 is stable, and the mounting stability of the battery body 100a can be better.

[0198] In some embodiments, the first connection portion 521 and the second connection portion 522 are integrally formed.

[0199] The first connection portion 521 and the second connection portion 522 are integrally formed, which means that the first connection portion 521 and the second connection portion 522 are manufactured through an integral molding process.

[0200] The first connection portion 521 and the second connection portion 522 are integrally formed, which is easy to prepare and has a stable structure.

[0201] like Figure 3 and Figure 13 As shown, Figure 13 This is a schematic diagram of the three-dimensional structure of a connecting bracket in a battery device provided in some other embodiments of the present application. In some embodiments, the second connecting component 52 further includes a third connecting portion 524, which is connected to the second connecting portion 522 and is used to connect to the main bracket 400. That is, the third connecting portion 524 connects the second connecting portion 522 and the main bracket 400.

[0202] The third connecting portion 524 is a component of the second connecting assembly 52. ​​The third connecting portion 524 can be composed of one or more parts.

[0203] The third connection portion 524 is suitable for a case where the distance between the main frame 400 and the battery body 100 a is large and the combination structure of the main frame 400 and the first connection assembly 51 and the buffer member 53 cannot be connected by the first connection portion 521 and the second connection portion 522 .

[0204] In some embodiments, the buffer component is integrally connected to the first connecting component and the second connecting component by injection molding.

[0205] During preparation, the first connecting component and the second connecting component can be prepared and formed first, and their positions can be placed and fixed using injection molding equipment. Then, the injection molding material required to prepare the buffer part can be injected between the first connecting component and the second connecting component, so that the injection molding material fills the preset space between the first connecting component and the second connecting component. Then, the injection molding material is cooled and formed to prepare the buffer part.

[0206] By adopting the solution provided in this embodiment, the buffer component can be tightly connected to the first connecting component and the second connecting component, so that the structure of the connecting bracket is stable.

[0207] In some embodiments, at least a portion of the buffer member 53 is an elastic portion.

[0208] There are several cases where at least one buffer portion of the buffer member 53 is an elastic portion: first, a portion of the buffer member 53 is an elastic portion and another portion is a non-elastic portion; second, the entire buffer member 53 is an elastic portion.

[0209] Elasticity refers to the property of an object that can return to its original size and shape after deformation. The fact that at least a portion of the buffer 53 is elastic means that at least a portion of the buffer 53 can absorb loads in multiple directions and return to its original shape after the load is removed.

[0210] By adopting the solution provided in this embodiment, at least a portion of the buffer member 53 can be made elastic. The damping characteristics of the elastic portion can absorb high-frequency vibrations to which the electrical device is subjected during use, such as high-frequency vibrations (50-1000 Hz) generated by the motor / road surface, thereby reducing the vibration energy transmitted to the battery body 100a by more than 60%, thereby reducing the risk of micro-damage to the internal structure of the battery body 100a; by adjusting the stiffness of the elastic portion (usually designed to be in the range of 20-50 N / mm), the natural frequency of the battery body 100a system is made to avoid the main excitation frequency of the main part of the electrical device (such as the motor fundamental frequency of 20-200 Hz), thereby preventing fatigue fracture caused by resonance.

[0211] In some embodiments, the buffer member 53 is an integrally formed member.

[0212] An integrally formed part is a part that is formed by processing the buffer 53 into a complete form at one time through an integral molding process, avoiding assembly or splicing to improve strength, aesthetics, or production efficiency. The integral molding process can be injection molding, 3D printing, etc., and the specific process can be determined according to the use requirements.

[0213] The buffer member 53 is an integrally formed member, which can make the buffer member 53 structurally stable and easy to manufacture.

[0214] In some embodiments, the buffer member 53 is a rubber member.

[0215] The buffer 53 is made of rubber, which can make the buffer 53 have excellent shock absorption and cushioning performance, adapt to complex environments, and have low production costs. It can be made into complex shapes through molding, extrusion and other processes. The density is lower than metal, and it is suitable for weight-sensitive applications.

[0216] In some possible implementations, the first direction is perpendicular to the height direction.

[0217] This makes design and processing easier.

[0227] The main body 511 is an integrally formed part. At least a portion of the second connecting component 52 is embedded in the buffer member 53 .

[0228] The second connecting component 52 includes a first connecting portion 521 and a second connecting portion 522 . The first connecting portion 521 is connected to the buffer component 53 and is arranged around at least a portion of the outer peripheral wall of the buffer component 53 .

[0229] In some embodiments, the first connecting portion 521 and the first connecting assembly 51 are connected to form a receiving cavity having at least one opening, and at least a portion of the buffer member 53 is disposed in the receiving cavity.

[0230] The first connecting portion 521 includes a surrounding portion 5211 and a second side portion 5212. The surrounding portion 5211 is arranged to surround at least a portion of the first connecting component 51 and is spaced apart from the first connecting component 51.

[0236] In the prior art, the complexity of the vehicle body and the dual-hole mounting point structure of the battery body 100a (which has two mounting holes) conflicted, making it impossible to directly use the traditional rubber shock-absorbing bracket structure. Furthermore, the current structure is expensive to produce, necessitating the simplification and cost reduction of the shock-absorbing bracket components.

[0237] The design of the shock-absorbing structure must simultaneously meet the vehicle body envelope requirements and the interface for the mounting holes of the battery body 100a. These two constraints increase the complexity of the design. This complexity further increases the requirements for the mounting connection bracket 500 with a shock-absorbing structure. The mounting connection bracket 500 must have higher precision, strength, and durability. However, higher design requirements and technical standards will increase costs (including R&D costs, material costs, and manufacturing costs), resulting in higher costs for the mounting connection bracket 500 and the electrical device.

[0238] The aforementioned body envelope requirement refers to the space constraints both inside and outside the vehicle body. The design of the shock-absorbing structure must be completed within these constraints. The mounting interface of the battery body 100a refers to the specific location and form of the interface connecting the battery body 100a to the vehicle body. The shock-absorbing structure must precisely match these interfaces to ensure that the battery body 100a can be securely mounted on the vehicle body.

[0239] The electrical device provided in this embodiment not only meets the requirements of the vehicle body envelope and the mounting interface of the battery device 100, but also has a low cost. Specifically, when the electrical device provided in this embodiment is a vehicle, due to the provision of multiple first connecting assemblies 51, the mounting method of the battery device 100 is optimized through biaxial locking, improving the vibration reduction capability in all directions. It is easy to install and can be directly installed on the bottom of the beam without the need for additional adapter brackets. While enhancing the mounting capability of the battery device 100, the connecting bracket 500 is highly adaptable and easy to install, improving its adaptability to vehicle body vibration. Compared with the existing technology, the number of connecting brackets 500 used can be reduced, simplifying the electrical device structure, and reducing its operating cost while maintaining its adaptability to multiple interfaces and vibration reduction capability. Therefore, the electrical device provided in this embodiment adopts a low-cost vibration-damping and torsion-resistant bracket (i.e., the aforementioned connecting bracket 500) that is integrated with the vehicle frame, thereby achieving vibration reduction of the battery device 100, easy installation structure, and multiple mounting interface adaptability. In addition, the connection bracket 500 in this embodiment can be positioned according to the frame interface and the mounting requirements of the battery device 100. On the basis of ensuring the shock absorption capability of the rubber, the shape of the connection bracket 500 can be changed to adapt to various scene requirements.
