Description

Technical Field

[0001] This application relates to the field of battery technology, and more particularly to a battery device and an electrical appliance. Background Technology

[0002] Battery devices, as a clean and efficient new energy source, are widely used in various industries such as automobiles, ships, forklifts, and energy storage. A battery device can include a casing and individual battery cells housed within it. To resist deformation of the individual cells and to isolate them from other electrical components, separators are installed inside the casing. Some components of the battery device are housed on the separators, enabling the device to perform specific functions. For example, the separators may have mounting bases that support conductive components, allowing the individual cells to charge and discharge. Due to the large number of components in a battery device, different molds are required for manufacturing, and the assembly process is complex and costly. Utility Model Content

[0003] This application provides a battery device and an electrical appliance.

[0004] The battery device according to the present application includes a housing, a separator, and a reinforcing plate. The housing has a receiving space. The separator is disposed in the housing and fixedly connected to the housing. The separator divides the receiving space into at least two sub-spaces. The separator has a receiving groove. The reinforcing plate is detachably disposed in the receiving groove. The reinforcing plate has a mounting base for mounting conductive components. The mounting base and the reinforcing plate are an integral structure.

[0005] In the battery device of this application embodiment, the reinforcing plate can increase the strength of the separator. In addition, the reinforcing plate and the mounting base are integrated into one structure, which reduces the number of parts in the battery device. This results in fewer molds being used in the production and manufacturing process of the battery device, and reduces the assembly steps of the parts, thereby reducing the production and manufacturing cost of the battery device.

[0006] In some embodiments, the partition includes two opposing panels with the receiving groove formed between them. This allows a reinforcing plate to be sandwiched between the two panels, improving the stability of the reinforcing plate.

[0007] In some embodiments, the receiving groove is provided with a plurality of connecting plates, the connecting plates are connected to the panel, the plurality of connecting plates are arranged at intervals along the length direction of the panel, and the reinforcing plate is provided between at least two adjacent connecting plates.

[0008] In this way, the connecting plate can restrict the installation position of the reinforcing plate and improve the positional stability of the reinforcing plate.

[0009] In some embodiments, both ends of the reinforcing plate along its length abut against corresponding connecting plates. In this way, the degree of freedom of the reinforcing plate along its length is restricted by the connecting plates, which can further improve the positional stability of the reinforcing plate.

[0010] In some embodiments, the reinforcing plate is a corrugated plate, with the crests and / or troughs of the corrugated plate abutting against the panel. This increases the deformability of the corrugated plate, further strengthening the partition.

[0011] In some embodiments, the mounting base is partially embedded in the receiving groove and protrudes from the top edge of the panel. This partial embedding of the mounting base in the receiving groove provides greater stability to its position. Furthermore, the protrusion of the mounting base from the top edge of the panel facilitates the installation of conductive components on the mounting base, reducing the risk of contact between conductive components and the partition.

[0012] In some embodiments, the mounting base abuts against the corresponding panels on both sides along the thickness direction of the panels. In this way, the two panels restrict the degrees of freedom of the mounting base in the thickness direction, making the mounting base more stable.

[0013] In some embodiments, the mounting base includes a mounting surface facing away from the bottom of the housing, and the mounting base has a mounting hole recessed from the mounting surface. This mounting hole facilitates the mounting of conductive components onto the mounting base.

[0014] In some embodiments, there are multiple reinforcing plates arranged along the length of the partition, and each reinforcing plate is connected to the mounting base. In this way, multiple reinforcing plates can reinforce different parts of the partition, improving the partition's resistance to deformation.

[0015] In some embodiments, the ratio of the sum of the lengths of the plurality of reinforcing plates to the length of the partition is in the range of 0.5-0.9 along the length direction of the partition.

[0016] In this way, the length of the multiple reinforcing plates is relatively large, which can provide a good reinforcement effect to the partition.

[0017] In some embodiments, the partition is a metal plate and the reinforcing plate is a plastic plate. This results in a stronger partition, which improves its resistance to deformation; and the plastic reinforcing plate is easier to manufacture.

[0018] The electrical equipment described in this application includes at least one battery device as described in any of the embodiments.

[0026] Please see Figures 1-3 The battery device 100 of this application includes a housing 10, a separator 20, and a reinforcing plate 30. The housing 10 has a receiving space 11. The separator 20 is disposed inside the housing 10 and fixedly connected to the housing 10. The separator 20 divides the receiving space 11 into at least two sub-spaces 111. The separator 20 has a receiving groove 21. The reinforcing plate 30 is detachably disposed in the receiving groove 21. The reinforcing plate 30 has a mounting base 40 for mounting conductive components. The mounting base 40 and the reinforcing plate 30 are an integral structure.

[0027] In the battery device 100 of this application embodiment, the reinforcing plate 30 can increase the strength of the separator 20. In addition, the reinforcing plate 30 and the mounting base 40 are an integral structure, which reduces the number of parts in the battery device 100. This reduces the number of molds used in the production and manufacturing process of the battery device 100 and reduces the assembly process of parts, thereby reducing the production and manufacturing cost of the battery device 100.

[0028] Specifically, the housing 10 is an external part of the battery device 100, serving to protect the internal parts of the battery device 100. The partition 20 is, for example, a metal plate, and can be fixedly connected to the housing 10 by welding. The partition 20 is vertically arranged, thereby dividing the receiving space 11 of the housing 10 to form multiple sub-spaces 111. The partition 20 has a hollow structure to form receiving grooves 21.

[0029] The reinforcing plate 30 strengthens the partition 20. The partition 20 and reinforcing plate 30 are molded separately for easy installation into the receiving groove 21 of the partition 20. Both the reinforcing plate 30 and the mounting base 40 are made of materials such as plastic, and the mounting base 40 and reinforcing plate 30 can be formed into a single structure through injection molding. The reinforcing plate 30 and partition 20 are detachably connected, thus improving the maintainability of the reinforcing plate 30. For example, if the performance of the reinforcing plate 30 is insufficient, it can be replaced.

[0030] The mounting base 40 can be disposed on top of the reinforcing plate 30. The conductive component mounted on the mounting base 40 includes a conductive structure that enables electrical connection between the two components. For example, the conductive component can lead out the individual cell 50 of the battery device 100.

[0031] Please see Figures 1-3 In some embodiments, the partition 20 includes two opposing panels 22, with a receiving groove 21 formed between the two panels 22. In this way, the reinforcing plate 30 can be sandwiched between the two panels 22, which helps to improve the stability of the reinforcing plate 30.

[0032] Specifically, the two panels 22 are generally flat and spaced apart to facilitate the formation of the receiving groove 21. The two panels 22 can be made of metal, and both panels 22 can be welded and fixed to the housing 10 to form an integral structure with the housing 10, which helps to improve the stability of the connection of the partition 20.

[0033] Please see Figures 1-3 In some embodiments, the receiving groove 21 is provided with a plurality of connecting plates 23, which are connected to the panel 22. The plurality of connecting plates 23 are arranged at intervals along the length direction of the panel 22, and a reinforcing plate 30 is provided between at least two adjacent connecting plates 23. In this way, the connecting plates 23 can restrict the installation position of the reinforcing plate 30 and improve the positional stability of the reinforcing plate 30.

[0034] Specifically, the thickness direction of the connecting plate 23 can be perpendicular to the thickness direction of the panel 22. The connecting plate 23 extends from the bottom to the top of the panel 22, which can strengthen the panel 22. The connecting plate 23 can connect one panel 22 or two panels 22. The number of connecting plates 23 can be two, three, four, etc.

[0035] When the reinforcing plate 30 deforms or the battery device 100 shakes as a whole, causing the reinforcing plate 30 to tend to move, the connecting plate 23 can restrict the position of the reinforcing plate 30, thereby ensuring the reinforcing effect of the reinforcing plate 30 on the separator 20.

[0036] In some embodiments, the two ends of the reinforcing plate 30 in the longitudinal direction abut against the corresponding connecting plates 23. In this way, the degree of freedom of the reinforcing plate 30 in the longitudinal direction is restricted by the connecting plates 23, which can further improve the positional stability of the reinforcing plate 30.

[0037] In one example, when installing the reinforcing plate 30, the reinforcing plate 30 can be pre-deformed along its own length to shorten its length. Then, the reinforcing plate 30 is installed into the receiving groove 21. After the force applied to the reinforcing plate 30 is unloaded, the reinforcing plate 30 returns to its original shape and then its two ends abut against the connecting plate 23.

[0038] In other words, the reinforcing plate 30 is assembled in the receiving groove 21 with an interference fit to ensure that the interface pre-stress is evenly distributed, thereby improving the shear resistance of the reinforcing plate 30 to resist the load of the expansion of the battery cell 50.

[0039] Please see Figures 1-3 In some embodiments, the reinforcing plate 30 is a corrugated plate, with the crests and / or troughs of the corrugated plate abutting against the panel 22. This increases the deformability of the corrugated plate, further strengthening the separator 20. Specifically, when the separator 20 is subjected to the expansion and deformation of the battery cell 50 on one side, the separator 20 bends and stretches accordingly, thereby causing the reinforcing plate 30 to stretch and deform as well. The corrugated structure of the reinforcing plate 30 enhances its stretchability, allowing it to absorb more external force, thus reducing the degree of deformation of the separator 20 and strengthening its overall strength.

[0040] Please see Figures 1-2 In some embodiments, the mounting base 40 is partially embedded in the receiving groove 21 and protrudes from the top edge of the panel 22. This partial embedding of the mounting base 40 in the receiving groove 21 provides greater stability to its position. Furthermore, the protrusion of the mounting base 40 from the top edge of the panel 22 facilitates the mounting of conductive components on the mounting base 40, reducing the risk of contact between conductive components and the partition 20.

[0041] Specifically, since the partition 20 includes two opposing panels 22, and the reinforcing plate 30 and the mounting base 40 are integrally formed, the mounting base 40 can be embedded in the receiving groove 21 when the reinforcing plate 30 is inserted from the top of the receiving groove 21. Because no notch needs to be made on the partition 20 for mounting the mounting base 40, no assembly gap is formed between the partition 20 and the mounting base 40, avoiding the risk of overheating and fire due to excessive contact resistance, as well as the risk of electrical short circuit due to insulation failure.

[0042] Please see Figures 1-3 In some embodiments, the mounting base 40 abuts against the corresponding panels 22 on both sides along the thickness direction of the panel 22. In this way, the two panels 22 restrict the degrees of freedom of the mounting base 40 in the thickness direction, making the mounting base 40 more stable and preventing it from loosening, thereby ensuring the stability of the conductive components mounted on the mounting base 40. Specifically, the mounting base 40 is block-shaped, and the side of the mounting base 40 facing the panel 22 is flat. The dimensional tolerances of the mounting base 40 can be set so that when the mounting base 40 is inserted into the receiving groove 21, both sides of the mounting base 40 abut against the corresponding panels 22.

[0043] Please see Figure 4In some embodiments, the mounting base 40 includes a mounting surface 41 facing away from the bottom of the housing 10, and the mounting base 40 has a mounting hole 42 recessed from the mounting surface 41. Thus, the mounting hole 42 facilitates the mounting of conductive components onto the mounting base 40. Specifically, the mounting surface 41 can be a plane, providing support for the conductive components. The mounting hole 42 can be, for example, a threaded hole, allowing the conductive components to be mounted onto the mounting base 40 using screws.

[0044] Please see Figures 1-3 In some embodiments, there are multiple reinforcing plates 30, which are arranged along the length of the partition 20, and each reinforcing plate 30 is connected to a mounting base 40. In this way, multiple reinforcing plates can reinforce different parts of the partition 20, thereby improving the deformation resistance of the partition 20.

[0045] In some embodiments, the ratio of the sum of the lengths of the plurality of reinforcing plates 30 to the length of the partition 20 along its length direction ranges from 0.5 to 0.9. For example, the ratio of the sum of the lengths of the plurality of reinforcing plates 30 to the length of the partition 20 ranges to values ​​such as 0.5, 0.6, 0.7, 0.8, and 0.9. In this way, the length of the plurality of reinforcing plates 30 is relatively large, which can provide better reinforcement to the partition 20.

[0046] In some embodiments, the partition 20 is a metal plate and the reinforcing plate 30 is a plastic plate. In this way, the partition 20 has greater strength, which is beneficial to improving the resistance to deformation of the partition 20; the reinforcing plate 30 is made of plastic, which is easier to manufacture and shape. The electrical equipment described in this application includes at least one battery device 100 according to any of the embodiments. Specifically, the electrical equipment includes, but is not limited to, aircraft, vehicles, energy storage devices, etc.
