[0051] Currently, from the perspective of the development of the market situation, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in many fields such as military equipment and aerospace. With the continuous expansion of the application fields of batteries, the market demand is also constantly increasing.

[0052] Among them, the battery device includes a battery box body and one or more battery modules arranged in the battery box body. The battery device usually also includes an FPC. The FPC can flexibly connect the battery modules together. In the related art, after the FPC is fixed on the battery module, when the battery module expands or the FPC itself expands and cannot be relieved, it is easy for the side of the FPC to warp or curl.

[0053] Based on the above considerations, in order to solve the technical problem that the side of the FPC in the prior art is prone to warp or curl, the present application proposes a fixing device, a battery device, and an electrical device for the FPC. The fixing device has a first fixing member and a second fixing member. The first fixing member can be detachably fixed on one side of the second fixing member; when the first fixing member is fixed on one side of the second fixing member, there is a through groove for the FPC to pass through between the first fixing member and the second fixing member, which can reduce the warping or curling problem of the side of the FPC due to expansion.

[0054] For the convenience of description in the following embodiments, a vehicle is taken as an example of an electrical device in an embodiment of the present application for illustration.

[0055] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a vehicle according to one or more embodiments.

[0056] Vehicle 1000 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, an extended-range vehicle, etc. A battery device 100 is disposed inside the vehicle 1000. The battery device 100 can be disposed at the bottom, head, or tail of the vehicle 1000. The battery device 100 can be used to supply power to the vehicle 1000. For example, the battery device 100 can serve as the operating power source of the vehicle 1000. The vehicle 1000 can also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300. For example, it is used for the working power requirements during the start, navigation, and driving of the vehicle 1000.

[0057] In some embodiments of the present application, the battery device 100 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0058] To improve the performance of the electrical device, the present application provides a fixing device for an FPC. Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of a perspective of the FPC fixed on the fixing device according to one or more embodiments.

[0059] In some embodiments, the fixing device 10 includes a bracket 20 and a fitting 30. The bracket 20 includes a first fixing member 21 and a second fixing member 22. The first fixing member 21 can be detachably fixed to one side of the second fixing member 22. When the first fixing member 21 is fixed to one side of the second fixing member 22, there is a through slot 23 between the first fixing member 21 and the second fixing member 22 for the FPC 40 to pass through. The fitting 30 is connected to the bracket 20.

[0060] The material of the bracket 20 can be plastic, copper, iron, aluminum, stainless steel, aluminum alloy, etc. The fixing device 10 fixes the FPC 40 by passing the FPC 40 through the through slot 23. Among them, the through slot 23 can be in the shape of a long rectangular body, a cylindrical body, an irregular polyhedron, etc. The FPC 40 passes through the through slot 23, and the slot wall of the through slot 23 plays a limiting role on the FPC 40. Compared with the prior art in which the FPC 40 is rigidly fixed by a fixing plate or rivets, etc., in this embodiment, in the thickness direction of the FPC 40, the size of the through slot 23 is larger than the size of the FPC 40, so that the fixing of the through slot 23 to the FPC 40 is a non-rigid fixing, and there is a certain amount of movement and expansion space for the FPC 40 in the thickness direction. In addition, the first fixing member 21 and the second fixing member 22 can be in the shape of a rod, a block, a plate, etc. The first fixing member 21 can be detachably fixed to one side of the second fixing member 22, that is, the first fixing member 21 can be fixed to the second fixing member 22, and the first fixing member 21 can also be separated from the second fixing member 22. The detachable fixing makes it convenient for the assembly and disassembly of the FPC 40. In addition, the FPC 40 can be adjusted to a natural state when assembling the FPC 40. Among them, the first fixing member 21 can be detachably fixed to the second fixing member 22 by one or more of a bolt structure, a magnetic attraction structure, a hinge structure, and a buckle structure. The fitting 30 is used to fix the bracket 20 on the battery module. In this embodiment, the fitting 30 is arranged on the first fixing member 21. In some other embodiments, the fitting 30 can also be arranged on the second fixing member 22. In addition, the fitting 30 can specifically be in the structure of a screw, a rivet, a bolt, etc.

[0061] In the above structure, the fitting 30 of the fixing device 10 is used to be fixed on the battery module, and the through slot 23 of the fixing device 10 allows the FPC 40 to pass through to limit and fix the FPC 40. The fixing device 10 fixes the FPC 40 by passing the FPC 40 through the through slot 23, so that the FPC 40 is not rigidly fixed on the battery module, and the FPC 40 can have a certain amount of movement and expansion in the through slot 23. The fixing method of the FPC 40 is floating fixing, and the through slot 23 can relieve the expansion and reduce the warping or curling problem of the side part of the FPC 40 due to expansion.

[0062] In some embodiments, the first fixing member 21 is a first baffle, the second fixing member 22 is a second baffle, and the first baffle and the second baffle enclose to form the through slot 23.

[0063] In this embodiment, the first fixing member 21 and the second fixing member 22 are plate-like structures. The setting of the plate-like structures enables the FPC 40 to have a larger contact area with the first fixing member 21 and the second fixing member 22 after passing through the through groove 23, reducing the problem of damage to the FPC 40 caused by excessive local stress on the FPC 40, and also improving the fixing effect on the FPC 40 through a larger contact area. The first fixing member 21 and the second fixing member 22 can specifically be bent plates or flat plates. When the first fixing member 21 and the second fixing member 22 are flat plates, the first fixing member 21 and the second fixing member 22 can be in the shape of a rectangle, a circle, an irregular polygon, etc.

[0064] As described above, the first baffle and the second baffle enclose to form the through groove 23, which can enable the FPC 40 to have a larger contact area with the through groove 23 and reduce the pressure locally applied to the FPC 40; in addition, the first baffle and the second baffle can also play a role in protecting the FPC 40.

[0065] Please refer to Figure 3 , Figure 3 FIG. is a schematic structural view of the FPC fixed on the fixing device according to one or more embodiments from another perspective. In some embodiments, the second baffle is a flat plate, and the first baffle includes an intermediate section 211 and connecting sections 212 provided on both sides of the intermediate section 211. The connecting sections 212 are arranged at an angle with the intermediate section 211, and both sides of the second baffle are respectively connected to the two connecting sections 212.

[0066] In this embodiment, the second baffle is a flat plate and the first baffle is a bent plate. In some other embodiments, it is also possible that the second baffle is a bent plate and the first baffle is a flat plate. In addition, the first baffle and the second baffle can also both be bent plates. In this embodiment, the intermediate section 211 of the first baffle and the connecting sections 212 on both sides thereof are integrally formed structures. In some other embodiments, the intermediate section 211 and the connecting sections 212 on both sides can also be connected together by means such as heat melting, welding, screws, etc. In this embodiment, the intermediate section 211 is perpendicular to the connecting sections 212. In some other embodiments, the angle between the intermediate section 211 and the connecting sections 212 can also be an obtuse angle or an acute angle.

[0067] As described above, the first baffle and the second baffle can enclose to form the through groove 23.

[0068] In some embodiments, one side of the first fixing member 21 is fixed to one side of the second fixing member 22 through a hinge structure 25, and the other side of the first fixing member 21 is detachably fixed to the other side of the second fixing member 22 through a snap structure 24.

[0069] The hinge structure 25 enables one side of the first fixing member 21 to rotate on one side of the second fixing member 22. When assembling the FPC 40, the other side of the first fixing member 21 can be separated from the second fixing member 22. Rotate the first fixing member 21 to open the through slot 23. After placing the FPC 40 on the second fixing member 22 and adjusting it to the natural state, then rotate the first fixing member 21 and fix the other side of the first fixing member 21 to the other side of the second fixing member 22 through the buckle structure 24, so that the FPC 40 can be fixed in the fixing through slot 23 of the fixing device 10. The advantage of the above separable fixing is that when assembling the FPC 40 and separating the first fixing member 21 from the second fixing member 22, the first fixing member 21 and the second fixing member 22 are not completely disassembled, which is convenient for the first fixing member 21 and the second fixing member 22 to be fixed together again. In some other embodiments, both sides of the first fixing member 21 and both sides of the second fixing member 22 can be fixed together through the buckle structure 24. Among them, the separable fixing can also be realized by other means such as bolt structure, magnetic attraction structure, hinge structure 25, buckle structure 24, etc.

[0070] As described above, the hinge structure 25 enables one side of the first fixing member 21 to rotate on one side of the second fixing member 22, and the buckle structure 24 can fix or separate the other side of the first fixing member 21 from the other side of the second fixing member 22, which is convenient for fixing the FPC 40 and can also adjust the FPC 40 to the natural state during fixing.

[0071] In some embodiments, the fixing device 10 further includes: a floating limiting member 50, and the floating limiting member 50 is located in the through slot 23.

[0072] The floating limiting member 50 is used to clamp and fix the FPC 40 in the through slot 23 to reduce the shaking of the FPC 40 in the through slot 23. In addition, the fixing of the floating limiting member 50 to the FPC 40 is not a rigid fixing. When expansion occurs, the FPC 40 can also squeeze the floating limiting member 50, so that the floating limiting member 50 can deform or move to absorb the expansion, reducing the warping or curling problem of the side of the FPC 40 due to expansion. The number of floating limiting members 50 can be one or more. In this embodiment, the floating limiting members 50 are arranged on the first fixing member 21 and the second fixing member 22. In some other embodiments, the floating limiting members 50 can be arranged only on the first fixing member 21 or the second fixing member 22.

[0073] As described above, the FPC 40 can be further limited in the through slot 23 by the floating limiting member 50 in the through slot 23. When the battery module or the FPC 40 expands, the floating limiting member 50 can deform or move, so that the FPC 40 can have a certain degree of movement and expansion in the through slot 23, reducing the warping or curling problem of the FPC 40.

[0074] In some embodiments, the floating limiting member 50 is one or more of a foam, a movable buckle, and an elastic member.

[0075] In this embodiment, the floating limiting member 50 is a foam. The foam has a porous structure and has a certain elasticity. The foam is disposed on the groove wall of the through groove 23. The foam can both limit and fix the FPC 40 in the through groove 23. When the battery module or the FPC 40 expands, the foam can also absorb the expansion by deforming, so that the FPC 40 can have a certain degree of movement and expansion in the through groove 23, reducing the warping or curling problem of the FPC 40. In some other embodiments, the floating limiting member 50 can also be an elastic member such as a movable buckle or rubber.

[0076] As described above, the type of the floating limiting member 50 can be adjusted according to requirements.

[0077] In some embodiments, the fitting 30 is disposed on the side of the second fixing member 22 facing away from the first fixing member 21, and the number of the fittings 30 is multiple.

[0078] In this embodiment, the fitting 30 is located on the second fixing member 22. In some other embodiments, the fitting 30 can also be located on the first fixing member 21. In this embodiment, the number of the fittings 30 is two. In some other embodiments, the number of the fittings 30 can be a reasonable number such as one, three, four, etc. In addition, the fitting 30 can be fixed to the second fixing member 22 by means of screws, threads, welding fixation, clamping fixation, etc. In this embodiment, the fitting 30 is a rivet. In some other embodiments, the fitting 30 can also be a screw, a pin, etc.

[0079] As described above, the fixing device 10 is fixed to the battery module through the fitting 30 on the second fixing member 22, and the FPC 40 is fixed by the through groove 23 on the bracket 20. The multiple fittings 30 make the fixing of the fixing device 10 more reliable.

[0080] In some embodiments, the second fixing member 22 is provided with a plurality of clamping portions 221, and each fitting 30 is disposed on each clamping portion 221.

[0081] The clamping portion 221 is used to fix the fitting 30. The clamping portion 221 is located on the side of the second fixing member 22 facing away from the first fixing member 21. In this embodiment, the clamping portion 221 is specifically a groove structure protruding on the second fixing member 22, and the groove structure and the second fixing member 22 are an integrally formed structure. The fitting 30 is clamped and fixed in the groove. In some other embodiments, the clamping structure can also be other types of clamping structures such as a hook structure or a clamping ring structure.

[0082] As described above, the fitting 30 can be fixed to the second fixing member 22 through the clamping portion 221.

[0083] In some embodiments, the clamping portion 221 protrudes from the second fixing member 22, and reinforcing ribs are provided between adjacent clamping portions 221.

[0084] The reinforcing ribs are arranged between two adjacent clamping portions 221, and the reinforcing ribs can be linear, wavy, grid-shaped, circular, polygonal, etc. The reinforcing ribs and the second fixing member 22 are of an integrally formed structure.

[0085] As described above, the reinforcing ribs can increase the structural strength of the fixing device 10.

[0086] In some embodiments, the fixing device 10 further includes: a stopper 60, the stopper 60 is connected to the bracket 20, and the stopper 60 and the fitting 30 are located on the same side of the bracket 20.

[0087] The stopper 60 is used to quickly position the fixing device 10 on the battery module when the fixing device 10 is fixed to the battery module through the fitting 30, thereby improving the assembly efficiency. In this embodiment, the stopper 60 is plate-shaped. When assembling the fixing device 10, the stopper 60 can abut against the end face on the side of the battery module, so as to realize the positioning of the fixing device 10. The stopper 60 is connected to the second fixing member 22. The stopper 60 and the second fixing member 22 can be of an integrally formed structure, and the stopper 60 can also be fixed to the second fixing member 22 by means of welding, screws, bolts, etc. In this embodiment, the stopper 60 is plate-shaped.

In some other embodiments, the fixing device 10 can be assembled to the FPC 40 later. The FPC 40 can be adjusted to the natural state during assembly and then the fixing device 10 can be assembled to achieve the function of redundant protection.

[0096] Correspondingly, the present application also proposes an electrical device, which includes the battery device 100. The battery device 100 is the battery device 100 in any of the above embodiments, and the battery device 100 is used to provide electrical energy.

[0097] Finally, in a specific application scenario, in view of the problem that the battery module in the existing battery device 100 expands or the FPC 40 itself expands and cannot be relieved, which easily causes the side of the FPC 40 to warp or curl. The fixing device 10 of the present application includes a bracket 20 and a fitting 30. The bracket 20 includes a first fixing member 21 and a second fixing member 22. The first fixing member 21 can be detachably fixed on one side of the second fixing member 22. When the first fixing member 21 is fixed on one side of the second fixing member 22, there is a through groove 23 for the FPC 40 to pass through between the first fixing member 21 and the second fixing member 22. The fitting 30 is connected to the bracket 20. The first fixing member 21 is a first baffle, the second fixing member 22 is a second baffle, and the first baffle and the second baffle enclose to form the through groove 23. The first baffle is a flat plate, the second baffle includes an intermediate section 211 and connecting sections 212 provided on both sides of the intermediate section 211. The connecting sections 212 are arranged at an angle with the intermediate section 211, and both sides of the first baffle are connected to the two connecting sections 212 respectively. One side of the first fixing member 21 is fixed on one side of the second fixing member 22 through a hinge structure 25, and the other side of the first fixing member 21 can be detachably fixed on the other side of the second fixing member 22 through a buckle structure 24. The fixing device 10 further includes: a floating limiting member 50, and the floating limiting member 50 is located in the through groove 23. The fitting 30 is arranged on the side of the second fixing member 22 facing away from the first fixing member 21, and the number of the fittings 30 is multiple. The fitting 30 is a rivet. The first fixing member 21 and the second fixing member 22 are injection molded parts.

[0098] In the above manner, the fitting 30 of the fixing device 10 is used to be fixed on the battery module, and the through groove 23 of the fixing device 10 is for the FPC 40 to pass through to limit and fix the FPC 40. The fixing device 10 fixes the FPC 40 by passing the FPC 40 through the through groove 23, so that the FPC 40 is not rigidly fixed on the battery module. The FPC 40 can have a certain degree of movement and expansion in the through groove 23. The fixing method of the FPC 40 is floating fixation, and the through groove 23 can relieve the expansion and reduce the warping or curling problem of the side of the FPC 40 due to expansion.
