Description

Technical Field

[0002] Battery devices are increasingly used in daily life and industry; for example, new energy vehicles equipped with battery devices are widely used. Typically, battery devices are mounted to the mounting frame of electrical appliances using bolts and other connectors, forming a rigid connection structure. When the electrical appliance is running, the vibrations generated by the appliance transmit stress to the battery device through this rigid connection structure, potentially leading to loosening of connectors and structural damage to the battery device. To address this, a buffer is usually added between the battery device and the mounting frame to mitigate these problems; however, this buffer is prone to displacement during installation, resulting in low assembly efficiency.

The buffer structure can absorb vibrations from the mounting frame, reducing the risk of vibration transmission to the battery device and causing battery device failure, thereby improving the safety of the battery device and extending its service life. At least a portion of the first connecting part of the buffer structure is sandwiched between the mounting bracket and the connecting bracket, which can reduce the transmission of vibrations on the mounting bracket to the connecting bracket along the first direction through the first connector, thereby reducing the transmission of vibrations on the mounting frame to the battery device along the first direction through the first connector. The buffer structure can be fixed to the mounting bracket or the connecting bracket by the second connector, realizing the pre-fixation of the buffer structure, improving the installation convenience and assembly efficiency of the buffer structure, and facilitating the disassembly and replacement of the buffer structure.

Figure 9 The buffer structure 40 can be a one-piece structure, combined with Figure 10 The buffer structure 40 can also be a split structure. In the second, third, and fourth cases, combined with... Figures 11 to 13 The buffer structure 40 is a split structure.

[0087] In some embodiments, the second connecting portion 41 is formed with a through hole 42, and the mounting bracket 10 is formed with a through hole. The through hole and the mounting hole 11 are spaced apart. The second connecting member 60 passes through the through hole 42 and the through hole to connect the second connecting portion 41 to the mounting bracket 10.

[0088] In other embodiments, the second connecting portion 41 has a through hole 42, the connecting bracket 20 has a through hole 22, the through hole 22 and the connecting hole 21 are spaced apart, and the second connecting member 60 passes through the through hole 42 and the through hole 22 to connect the second connecting portion 41 and the connecting bracket 20.

[0089] In some embodiments, the distance between the connecting bracket 20 and the mounting bracket 10 can be adjusted by positioning the second connecting portion 41 in the buffer structure 40 at different positions on the connecting bracket 20 and the mounting bracket 10. For example, the distance between the connecting bracket 20 and the mounting bracket 10 when the second connecting portion 41 is positioned on the side of the mounting bracket 10 away from the connecting bracket 20 is less than the distance between the connecting bracket 20 and the mounting bracket 10 when the second connecting portion 41 is positioned on the side of the mounting bracket 10 facing the connecting bracket 20.

[0090] In other embodiments, the distance between the connecting bracket 20 and the mounting bracket 10 can be adjusted by selecting buffer structures 40 of different sizes. For example, the larger the size of the first connecting portion 43 sandwiched between the connecting bracket 20 and the mounting bracket 10, the greater the distance between the connecting bracket 20 and the mounting bracket 10.

[0091] In the above embodiment, the second connecting part 41 can provide a connecting part for the buffer structure 40, which facilitates the pre-fixation of the buffer structure 40.

Figure 6 The first connecting part 43 may be partially inserted through the mounting bracket 10, and the second connecting part 41 may be a flange formed by the first connecting part 43 extending along the second direction Y, which abuts against the surface of the mounting bracket 10 away from the connecting bracket 20 along the first direction X.

[0094] The second connecting part 41 is provided on the side of the connecting bracket 20 opposite to the mounting bracket 10, that is, see... Figure 5 The first connecting part 43 can be partially inserted into the connecting bracket 20, and the second connecting part 41 can be a flange formed by the first connecting part 43 extending along the second direction Y. The flange abuts against the surface of the connecting bracket 20 away from the mounting bracket 10 along the first direction X.

[0095] In the above embodiments, the second connecting part 41 can limit and buffer the mounting bracket 10, reducing the risk of the mounting bracket 10 moving away from the side of the connecting bracket 20; or, the second connecting part 41 can limit and buffer the connecting bracket 20, reducing the risk of the connecting bracket 20 moving away from the side of the mounting bracket 10, thereby improving the connection stability between the mounting bracket 10 and the connecting bracket 20.

[0096] In some implementations, the buffer structure 40 passes through the mounting hole 11 and / or the connection hole 21.

[0097] For example, the first connecting portion 43 passes through the mounting hole 11 and / or the connecting hole 21.

[0098] The buffer structure 40 can be inserted only in the mounting hole 11, or only in the connecting hole 21, or partially in the mounting hole 11 and partially in the connecting hole 21.

[0099] The buffer structure 40 is inserted into the mounting hole 11. That is, from the center of the mounting hole 11 outwards radially, the components are the first connector 30, the buffer structure 40 and the mounting bracket 10 in sequence.

[0100] The buffer structure 40 is inserted into the connection hole 21. That is, from the center of the connection hole 21 outward along the radial direction, there are the first connector 30, the buffer structure 40 and the connection bracket 20 in sequence.

[0101] In the above embodiment, the buffer structure 40 can reduce the transmission of vibration on the mounting bracket 10 to the connecting bracket 20 through the first connector 30 along the aperture direction, thereby reducing the transmission of vibration on the mounting frame to the battery device 200 through the first connector 30 along the aperture direction.

First: A buffer structure 40 is provided between the stop part 33 and the connecting bracket 20, but no buffer structure 40 is provided between the locking member 34 and the mounting bracket 10. Second: No buffer structure 40 is provided between the stop part 33 and the connecting bracket 20, but a buffer structure 40 is provided between the locking member 34 and the mounting bracket 10. Third: A buffer structure 40 is provided between the stop part 33 and the connecting bracket 20, and a buffer structure 40 is also provided between the locking member 34 and the mounting bracket 10.

[0111] The first connecting member 30 can be a bolt, the stop part 33 is the head 31 of the bolt, and the locking member 34 can be a nut or a bushing.

[0115] In some implementation schemes, the buffer structure 40 is an integral structure.

[0116] An integrated structure refers to a buffer structure that is a single, inseparable unit.

[0117] For example, the buffer structure 40 is integrally formed.

[0118] In some embodiments, please refer to Figure 8The entire first connecting portion 43 is sandwiched between the mounting bracket 10 and the connecting bracket 20 in the first direction X. A second connecting portion 41 is formed on one side of the buffer structure 40 along the first direction X. The second connecting portion 41 abuts against one of the surfaces of the mounting bracket 10 and the connecting bracket 20 facing each other. Alternatively, please refer to... Figure 9 The buffer structure 40 has second connecting portions 41 formed on both sides along the first direction X. One side of the second connecting portion 41 abuts against the surface of the mounting bracket 10 facing the connecting bracket 20, and the other side of the second connecting portion 41 abuts against the surface of the connecting bracket 20 facing the mounting bracket 10.

[0119] In other embodiments, please refer to Figure 6 The buffer structure 40 passes through the mounting hole 11, and the second connecting part 41 abuts against any surface of the mounting bracket 10 along the first direction X; or, please refer to Figure 5 The buffer structure 40 passes through the connecting hole 21, and the second connecting part 41 abuts against any surface of the connecting bracket 20 along the first direction X.

[0120] In some other embodiments, please refer to Figure 7 The buffer structure 40 passes through the mounting hole 11 and the connecting hole 21, and the second connecting part 41 abuts against any surface of the mounting bracket 10 or the connecting bracket 20 along the first direction X.

[0121] In the above implementation scheme, the integrated structure facilitates the molding and installation of the buffer structure 40.

[0122] In some implementations, the buffer structure 40 is a split structure.

[0123] A split structure refers to a buffer structure consisting of multiple independent components.

[0124] For example, please refer to Figures 10 to 13 The buffer structure 40 includes two independent components that can be detachably connected to form the buffer structure 40. The independent components can be detachably connected using structures such as snaps or magnetic attraction.

[0125] In some embodiments, please refer to Figure 10 Both components are sandwiched between the mounting bracket 10 and the connecting bracket 20 in the first direction X and abut against each other. The second connecting part 41 on one component abuts against the surface of the mounting bracket 10 facing the connecting bracket 20 in the first direction X, and the second connecting part 41 on the other component abuts against the surface of the connecting bracket 20 facing the mounting bracket 10 in the first direction X.

[0126] In other embodiments, please refer to Figure 11One component is entirely sandwiched between the mounting bracket 10 and the connecting bracket 20 in the first direction X, and the second connecting portion 41 on this component abuts against the surface of the mounting bracket 10 facing the connecting bracket 20 in the first direction X. The other component passes through the connecting hole 21, and the second connecting portion 41 on this component abuts against any surface of the connecting bracket 20 in the first direction X; or, please refer to Figure 12 One component is sandwiched between the mounting bracket 10 and the connecting bracket 20 in the first direction X, and the second connecting portion 41 on the component abuts against the surface of the connecting bracket 20 facing the mounting bracket 10 in the first direction X. The other component passes through the mounting hole 11, and the second connecting portion 41 on the component abuts against any surface of the mounting bracket 10 in the first direction X.

[0127] In some other embodiments, please refer to Figure 13 One component is inserted into the mounting hole 11, and the second connecting portion 41 on the component abuts against any surface of the mounting bracket 10 along the first direction X; the other component is inserted into the connecting hole 21, and the second connecting portion 41 on the component abuts against any surface of the connecting bracket 20 along the first direction X.

[0128] In the above implementation scheme, the split structure is advantageous for selecting the size of each split component of the buffer structure 40, thereby increasing the practicality and flexibility of the buffer structure 40.

[0129] In some implementations, the buffer structure 40 is a non-metallic elastic structure.

[0130] The buffer structure 40 can be made of rubber, silicone, etc.

[0131] In the above implementation scheme, the non-metallic elastic structure can reduce rigid contact with the mounting bracket 10 and the connecting bracket 20 while buffering and shock absorption, thereby reducing wear on the mounting bracket 10 and the connecting bracket 20 and extending their service life.

[0132] In some implementations, the buffer structure 40 is a rubber structure.

[0133] The buffer structure 40 can be a rubber pad, rubber ring, etc.

[0134] In the above implementation scheme, the rubber structure has a good buffering and shock absorption effect.

[0136] The battery device 200 can provide electrical energy to electrical devices. Electrical devices may include vehicles, aircraft, etc.

[0137] The connection assembly 100 includes a mounting bracket 10, a connecting bracket 20, and a first connector 30. The mounting bracket 10 is fixed to the mounting frame, the connecting bracket 20 is fixed to the battery device 200, and the first connector 30 connects the mounting bracket 10 and the connecting bracket 20, thereby connecting the battery device 200 and the mounting frame.

[0138] In the electrical device of this application embodiment, the connection component 100 connects the battery device 200 and the mounting frame, which can improve the stability of the connection between the battery device 200 and the mounting frame, and at the same time reduce the vibration transmitted from the mounting frame to the battery device 200, thereby improving the safety of the electrical device.

[0139] In some implementations, there are multiple connection components 100, which are arranged at intervals.

[0140] In other words, there can be multiple mounting brackets 10 and multiple connecting brackets 20, with multiple mounting holes 11 formed on different mounting brackets 10 and multiple connecting holes 21 formed on different connecting brackets 20.

[0141] In some embodiments, multiple mounting brackets 10 are arranged at intervals and evenly distributed on opposite sides of the mounting frame. Multiple connecting brackets 20 are arranged at intervals and evenly distributed on opposite sides of the battery device 200.

[0142] In the above implementation scheme, the battery device 200 and the mounting frame are connected by multiple connecting components 100, which facilitates the maintenance of the mounting bracket 10 and connecting bracket 20 in a single connecting component 100 and reduces maintenance costs.

[0143] In some implementations, the number of connecting components 100 can be one. That is, the number of mounting brackets 10 and connecting brackets 20 is one, multiple mounting holes 11 are formed on the same mounting bracket 10, and multiple connecting holes 21 are formed on the same connecting bracket 20. This helps to improve the efficiency of assembly and disassembly of the connecting components 100.

[0144] In some implementations, the mounting bracket 10 is detachably connected to the mounting frame; and / or, the connecting bracket 20 is detachably connected to the battery device 200.

[0145] The above can include the following situations: First, the mounting bracket 10 is detachably connected to the mounting frame, while the connecting bracket 20 is not detachably connected to the battery device 200. Second, the mounting bracket 10 is not detachably connected to the mounting frame, while the connecting bracket 20 is detachably connected to the battery device 200. Third, the mounting bracket 10 is detachably connected to the mounting frame, and the connecting bracket 20 is also detachably connected to the battery device 200.

[0146] Detachable connections can be made using bolts, screws, clips, etc., while non-detachable connections can be made using welding, riveting, etc.

[0147] In the above implementation scheme, the mounting bracket 10 is detachably connected to the mounting frame; and / or the connecting bracket 20 is detachably connected to the battery device 200, which facilitates the disassembly and assembly of the mounting bracket 10 and the connecting bracket 20 and makes replacement easier.

[0148] In some implementations, the electrical device includes vehicle 1000, and the mounting frame includes the chassis of vehicle 1000.

[0149] In other words, vehicle 1000 includes battery device 200, chassis and connection assembly 100.

[0150] Vehicle 1000 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 vehicles, etc.

[0151] A battery device 200 can be mounted on the chassis. In some embodiments, a battery device 200 can be connected to the chassis via 8-12 connecting components 100.

[0152] In the above implementation scheme, by connecting the battery device 200 and the chassis of the vehicle 1000 through the connecting component 100, the stability of the connection between the battery device 200 and the chassis of the vehicle 1000 can be improved, while reducing the transmission of chassis vibration to the battery device 200, reducing the risk of battery device 200 failure, thereby improving the safety of the vehicle 1000.

[0153] In some implementations, the battery device 200 is located on the side of the chassis facing the ground, and the mounting bracket 10 is located above the connecting bracket 20.

[0154] The battery unit 200 is located on the side of the chassis facing the ground, that is, at least a portion of the chassis is located above the battery unit 200.

[0155] In some embodiments, the chassis forms an accommodating space, and an opening is formed at the bottom of the chassis, which communicates with the accommodating space. The battery device 200 can enter the accommodating space through the opening, and part of the battery device 200 is located in the accommodating space.

[0156] In the above embodiment, the mounting bracket 10 is located above the connecting bracket 20, which facilitates the adjustment of the ground clearance of the battery device 200 by selecting the size of the portion of the first connecting part 43 between the mounting bracket 10 and the connecting bracket 20.

The mounting bracket 10 is used to fix to the chassis of the vehicle 1000 and has a mounting hole 11. The connecting bracket 20 is used to fix to the battery device 200 and has a connecting hole 21. The first connector 30 passes through the mounting hole 11 and the connecting hole 21 to connect the mounting bracket 10 and the connecting bracket 20, thereby securely connecting the battery device 200 and the chassis of the vehicle 1000.

[0159] The buffer structure 40 includes a first connecting part 43 and a second connecting part 41. The first connecting part 43 is sleeved on the outer periphery of the first connecting member 30 and is at least partially sandwiched between the mounting bracket 10 and the connecting bracket 20 in the first direction X. This can reduce the transmission of vibration on the mounting bracket 10 to the connecting bracket 20 through the first connecting member 30 in the first direction X, thereby reducing the transmission of chassis vibration to the battery device 200 through the first connecting member 30 in the first direction X, reducing the risk of battery device 200 failure, and thus improving the safety of the vehicle 1000. The second connecting part 41 is detachably connected to the mounting bracket 10 or the connecting bracket 20, which can realize the pre-fixation of the buffer structure 40, improve the assembly efficiency of the buffer structure 40, and facilitate the disassembly and replacement of the buffer structure 40.
