This baffle fits snugly against the battery pack, providing some support and stability. However, because there is no connecting structure between the baffle and the battery cells, the cells may not be securely fixed. In the event of a drop or impact, the internal structure of the battery pack may shift, leading to damage to the battery cells. Utility Model Content

[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, it should be understood that the terms "thickness," "upper," "lower," "top," "bottom," "inner," "outer," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The following is for reference. Figure 1 - Figure 12 A power supply device 100 according to a first aspect embodiment of the present invention is described.

[0048] From the outside, the power supply unit 100 appears as follows: Figure 1 As shown. The power supply unit 100 includes a battery pack (not shown) disposed therein.

[0049] It is important to understand that the battery pack is a crucial component of the power supply unit 100, used to store and provide electrical energy. As the core component of the power supply unit 100, the battery pack contains multiple individual battery cells. These cells are interconnected in series or parallel through a precise electrical connection structure to achieve specific voltage and capacity output. These electrical connections typically include electrode tab welding between cells, bus connections, wire connections, etc., which together constitute the electrical network within the power supply unit 100.

[0050] Therefore, when the battery pack moves within the power supply unit 100, these electrical connections may be subjected to varying degrees of mechanical stress. This mechanical stress may originate from collisions, compression, or vibrations between the battery pack and surrounding structures. Under the influence of mechanical stress, the connection points may loosen, break, or deform. This loosening of electrical connections not only leads to a decline in the performance of the power supply unit 100, such as increased internal resistance and capacity decay, but may also cause more serious safety problems, such as short circuits, overheating, or even explosions.

[0051] Therefore, in order to improve the protection of the battery pack, the power supply device 100 of this utility model embodiment includes two baffles 10.

[0052] like Figure 2 - Figure 3 As shown, two baffles 10 are distributed along the circumference of the battery pack. The two baffles 10 are the first baffle 1 and the second baffle 2, respectively. The two ends of the first baffle 1 are the first end 11 and the second end 12, respectively. The two ends of the second baffle 2 are the third end 23 and the fourth end 24, respectively. The first end 11 is connected to the third end 23, and the second end 12 is connected to the fourth end 24, so as to form a circumferential limit on the battery pack.

[0053] Combination Figure 2 and Figure 3 The space between the two baffles 10 is used to place the battery pack.

[0054] By setting two circumferentially distributed baffles 10 and connecting them to form a ring structure, a circumferentially enclosing layout is created for the battery pack. Using two baffles 10 not only reduces the number of baffles and helps shorten assembly time, but also simplifies the assembly relationship between them and the battery pack, reducing the likelihood of jamming due to minor differences in components.

[0055] These two baffles 10 are fixed at both ends of the battery pack in the circumferential direction. When the battery pack expands, only the connection points at these two ends have relatively weak constraint in the entire circumferential region, while the overall constraint of the baffles 10 remains strong, thus providing more robust protection for the battery pack.

[0056] Specifically, the two ends of the first baffle 1 are the first end 11 and the second end 12, respectively, while the two ends of the second baffle 2 are the third end 23 and the fourth end 24, respectively. In terms of layout, the first end 11 of the first baffle 1 is connected to the third end 23 of the second baffle 2, and at the same time, the second end 12 of the first baffle 1 is also closely connected to the fourth end 24 of the second baffle 2, thereby constructing a ring-shaped protection structure surrounding the battery pack.

[0057] This design not only provides comprehensive physical protection for the battery pack, but also serves as a limiting function. The tight connection of the two baffles 10 securely fixes the battery pack, effectively preventing it from shifting inside the power supply unit 100 due to vibration or collision, thereby greatly reducing the risk of damage to the battery pack and improving the protection performance of the power supply unit 100 for the battery pack.

[0058] In some embodiments, the two baffles 10 can be connected by fasteners, such as bolts, screws, nuts, etc. This fastener connection ensures that the two baffles 10 can be tightly and firmly joined together, enhancing the connection strength between them. Furthermore, this enhanced connection strength provides a more effective limiting effect for the battery pack, preventing unnecessary displacement within the power supply unit 100, thereby ensuring the stability and safety of the battery pack.

[0059] Alternatively, the two baffles 10 can be connected via a self-locking structure. This self-locking structure can include elements such as snap-fits, latches, or pins to achieve automatic locking and connection between the two baffles 10. This connection method using a self-locking structure eliminates the need for additional fasteners. Furthermore, the self-locking structure enables quick and convenient assembly and disassembly, reducing production costs and facilitating maintenance.

[0060] It's important to understand that during charging and discharging, battery cells generate expansion forces due to internal chemical reactions and physical changes. If these expansion forces are not effectively controlled and suppressed, they will gradually accumulate, potentially increasing the cell's volume. When the cell expands to a certain extent, it will exert pressure on the battery pack's outer casing and other internal structures, causing the battery pack to deform. A deformed battery pack not only suffers cosmetic damage, but more importantly, its internal electrical connections and heat dissipation structures may be compromised, thus affecting the battery pack's performance and safety.

[0061] Therefore, the battery pack in this embodiment includes two baffles 10, which tightly surround the battery cell assembly to form a stable support frame. This frame effectively restricts the expansion space of the battery cell assembly, ensuring that the expansion of the cells is limited to a relatively small area. Simultaneously, the tight fit between the baffles 10 and the battery pack disperses the pressure generated by the cell expansion over a larger area, thereby reducing pressure on the battery pack casing and other internal structures.

[0062] According to some embodiments of the present invention, the power supply device 100 has two baffles 10 with the same shape.

[0063] First, the fact that two baffles 10 are identical in shape means that the same molds, production lines, and quality control standards can be used in the production process, thereby simplifying the production flow and improving production efficiency. This standardized production method reduces the complexity of adjusting the production line due to different components, making the assembly process smoother.

[0064] Secondly, the uniform shape of the baffles 10 eliminates the need to distinguish between left and right during assembly, reducing the identification burden on assembly personnel and lowering the risk of assembly errors. Workers only need to install the baffles 10 together according to the predetermined positions, simplifying the assembly process and improving assembly efficiency.

[0065] According to some embodiments of the present invention, in the power supply device 100, the first end 11 of the first baffle 1 is connected to the third end 23 of the second baffle 2.

[0066] Optionally, the first end 11 and the third end 23 are connected by means of a pin structure, a fastener, or a snap-fit ​​connection. Specifically, the connection method between the first end 11 and the third end 23 can achieve a stable connection between the two while also facilitating installation and disassembly.

[0067] According to some specific embodiments of this utility model, combined with Figures 3-4 The first baffle 1 is connected to the third end 23 of the second baffle 2 by a pin structure.

[0068] The pin structure, serving as the connecting component between the first baffle 1 and the second baffle 2, not only ensures a tight fit between the two baffles 10, forming a stable connection, but also effectively creates a circumferential limiting structure to prevent the battery pack from loosening due to vibration or external forces. This tight and stable connection provides a solid guarantee for the internal stability of the power supply device 100.

[0069] Furthermore, the pin structure facilitates disassembly. Specifically, when the power supply unit 100 requires maintenance or the baffle 10 needs replacement, the pin structure allows operators to easily perform disassembly without the aid of other tools. This design not only simplifies the maintenance process and improves work efficiency but also reduces maintenance costs.

[0070] In some alternative embodiments, the baffle 10 is made of plastic. Plastic materials have advantages such as being lightweight, high-strength, corrosion-resistant, and easy to process and mold, making them suitable for manufacturing the baffle 10. Through processes such as injection molding, the shape, size, and surface quality of the baffle 10 can be precisely controlled to meet the power supply device's requirements for baffle structural strength, sealing, and heat dissipation performance. Simultaneously, plastic materials also possess good insulation properties, helping to ensure the safe operation of the power supply device.

[0071] In some alternative embodiments, combined with Figure 3 - Figure 6The first baffle 1 has a first post 111 and a first pin 113 at its first end 11. The first post 111 has a first insertion hole 112, and the first post 111 and the first pin 113 are spaced apart along the height direction. The second baffle 2 has a second post 231 and a second pin 233 at its third end 23. The second post 231 has a second insertion hole 232, and the second post 231 and the second pin 233 are spaced apart along the height direction. The first pin 113 is inserted into the second insertion hole 232 of the second post 231, and the second pin 233 is inserted into the first insertion hole 112 of the first post 111. Here, the height direction refers to the height direction of the battery pack, which will not be elaborated further below.

[0072] In the above technical solution, the first baffle 1 is provided with a first post 111 and a first pin 113 at its first end 11 (i.e., one side or one end). These two components are distributed at intervals along the height direction of the battery pack, forming a stable support and connection structure.

[0073] Combination Figure 5 The first insertion post 111 is a protruding columnar structure with a first insertion hole 112. This first insertion hole 112 is configured to receive the second pin 233 of the second baffle 2, so as to realize the insertion and engagement between the two.

[0074] The first pin 113 is a slender columnar structure whose shape and size match the insertion hole on the second pin 231, and is used to insert into the second insertion hole 232 of the second pin 231.

[0075] Similar to the first baffle 1, the second baffle 2 also has a second post 231 and a second pin 233 at its third end 23 (i.e., the side or end corresponding to the first baffle 1). These two components are also spaced apart along the height direction of the battery pack, corresponding to the first post 111 and the first pin 113 of the first baffle 1.

[0076] Combination Figure 6 The second insertion post 231 is a protruding columnar structure with a second insertion hole 232. The second insertion hole 232 is used to receive the first pin 113 of the first baffle 1, so as to realize the insertion and engagement between the two.

[0077] The second pin 233 is a slender columnar structure whose shape and size match the first insertion hole 112 on the first insertion post 111. The second pin 233 is used to insert into the first insertion hole 112 of the first insertion post 111.

[0078] For example, during the plug-in connection, the first baffle 1 and the second baffle 2 are placed on both sides of the battery pack.

[0079] The first pin 113 of the first baffle 1 is inserted into the second insertion hole 232 of the second insertion post 231 of the second baffle 2, while the second pin 233 of the second baffle 2 is inserted into the first insertion hole 112 of the first insertion post 111 of the first baffle 1.

[0080] This plug-in method not only ensures a tight connection between the first baffle 1 and the second baffle 2, but also achieves stable support for both in the height direction of the battery pack through the cooperation of the plug and the plug hole.

[0081] On the one hand, through the above-mentioned plug-in connection, the first baffle 1 and the second baffle 2 form a stable frame inside the battery pack, effectively restricting the movement and expansion of the battery pack, thereby enhancing the overall stability of the power supply device 100.

[0082] On the other hand, through the above-mentioned plug-in connection, the first baffle 1 and the second baffle 2 can be easily disassembled and replaced when needed, without the need for additional tools or equipment, thus reducing maintenance costs and time.

[0083] Furthermore, the above-mentioned plug-in connection method can ensure that the first baffle 1 and the second baffle 2 occupy less horizontal space inside the battery pack, providing more horizontal space for the cell pack and optimizing the energy density and performance of the battery pack.

[0084] It is worth noting that, in some optional embodiments, the first baffle 1 forms a first insertion hole 112 and a first pin 113 at its first end 11. The second baffle 2 forms a second insertion hole 232 and a second pin 233 at its third end 23. The first insertion hole 112 and the second pin 233 are engaged, and the first pin 113 and the second insertion hole 232 are engaged. Specifically, the first insertion hole 112 is integrally formed in the first baffle 1, and the second insertion hole 232 is integrally formed in the second baffle 2. This arrangement ensures a stable connection and precise alignment between the first baffle 1 and the second baffle 2.

[0085] In some embodiments, the first post 111 and the first pin 113 are distributed sequentially along the height direction of the battery pack. The first pin 113 is disposed at the end of the first post 111 away from the opening of the first socket 112.

[0086] With this configuration, the first insertion post 111 and the first insertion pin 113 can be either a single piece or separate pieces.

[0087] Optionally, when the first insertion post 111 and the first pin 113 are integral parts, the first insertion post 111 is connected to the first pin 113, the first insertion post 111 is connected to the first baffle 1, and / or the first pin 113 is connected to the first baffle 1 through a connecting part.

[0088] Alternatively, when the first insertion post 111 and the first pin 113 are separate parts, the first insertion post 111 is connected to the first baffle 1, the first pin 113 is provided with a connecting part, and the first pin 113 is connected to the first baffle 1 through the connecting part.

[0089] In some optional such Figure 3 In the embodiment shown, the first pin 113 and the first socket 112 are coaxially arranged, and the second pin 233 and the second socket 232 are coaxially arranged.

[0090] The first pin 113 may be a cylindrical or similar cylindrical connecting member, which is configured to be inserted into a hole of a corresponding size.

[0091] The first socket 112 is a hole that matches the first pin 113 and can accommodate its insertion.

[0092] The coaxial arrangement means that the central axis of the first pin 113 coincides or nearly coincides with the central axis of the first socket 112. The positional relationship between the two in the height direction of the battery pack shows a high degree of alignment, making the docking of the pin and the socket more intuitive and easier.

[0093] In addition, the high coaxiality of the pins and sockets helps reduce local stress in the connection area caused by offset or tilt.

[0094] Specifically, if the coaxiality of the pin and the socket is not high, the pin may hit or rub against the edge of the socket due to inaccurate positioning after insertion, resulting in local stress concentration. In severe cases, it may even affect the stability and reliability of the connection structure between the two baffles 10.

[0095] When the coaxiality is high, the pin can be smoothly and unobstructedly inserted into the socket, and the force on the edge of the socket is uniform during the connection process, avoiding unnecessary impact and friction. In this way, the local stress in the connection area of ​​the two sockets will be reduced, thereby improving the life and reliability of the baffle 10.

[0096] In some alternative embodiments, the first pin 113 and the first socket 112 are coaxially arranged, and the second pin 233 and the second socket 232 are coaxially arranged.

[0097] Specifically, the first pin 113 and the first socket 112 are not located on the same straight line in space, but are offset to a certain extent. Similarly, the second pin 233 and the second socket 232 are also not located on the same straight line in space, and are also offset to a certain extent.

[0098] The different shaft settings create a certain friction between the pin and the socket after insertion, which can effectively prevent the pin from loosening under vibration or external force.

[0099] For example, when a power supply device is used in a vehicle, the friction between the pins and sockets on different shafts can resist the loosening caused by vibration when the vehicle vibrates during operation, thus maintaining the stability of the connection.

[0100] Furthermore, by using different shafts, the contact area and contact points between the pin and the socket are more evenly distributed, which helps to disperse stress, reduce local stress concentration, and extend the service life of the connector.

[0101] In addition, different axis settings can provide multiple positioning points. Even if one positioning point fails, the other positioning points can still maintain the stability of the connection, thereby increasing the overall reliability of the connection.

[0102] In some alternative embodiments, such as Figure 3 As shown, the first pin 113 and the first post 111 are integrally formed on the first baffle 1, and / or the second pin 233 and the second post 231 are integrally formed on the second baffle 2.

[0103] In the above technical solution, the first pin 113 and the first post 111 are integrally formed on the first baffle 1, and the second pin 233 and the second post 231 are integrally formed on the second baffle 2. These two designs can exist independently or simultaneously in the same embodiment. Specifically, when the first pin 113 and the first post 111 are integrally formed on the first baffle 1, or when the second pin 233 and the second post 231 are integrally formed on the second baffle 2, connection stability and reliability can be achieved. To further improve structural stability, the first pin 113 and the first post 111 are integrally formed on the first baffle 1, and the second pin 233 and the second post 231 are integrally formed on the second baffle 2.

[0104] Here, the concept of "integrated formation" should be interpreted broadly: it can refer to the first pin 113, the first post 111, and the first baffle 1 (as well as the second pin 233, the second post 231, and the second baffle 2) being directly formed into a single unit through a one-time manufacturing process (such as injection molding, casting, or forging); or it can refer to them being processed and formed separately first, and then combined into a single structure through some means (such as welding, bonding, or mechanical connection). The key is that, regardless of the processing sequence or method, the first pin 113, the first post 111, and the first baffle 1 (as well as the second pin 233, the second post 231, and the second baffle 2) must ultimately form an integrated structure after all processing steps are completed. This arrangement ensures the stability and reliability of the structure of the first baffle 1 with the first pin 113 and the first post 111, and the second baffle 2 with the second pin 233 and the second post 231.

[0105] According to some embodiments of the present invention, in the power supply device 100, the second end 12 of the first baffle 1 is engaged with the fourth end 24 of the second baffle 2.

[0106] Optionally, the second end 12 and the fourth end 24 are connected by means of a pin structure, a fastener, or a snap-fit ​​connection. Specifically, the connection method between the second end 12 and the fourth end 24 can ensure a stable connection between the two while facilitating installation and disassembly.

[0107] According to some specific embodiments of this utility model, combined with Figure 4 , Figure 7 The second end 12 of the first baffle 1 is connected to the fourth end 24 of the second baffle 2 by a snap fastener.

[0108] This snap-fit ​​connection ensures a secure connection between the first baffle 1 and the second baffle 2 while providing a convenient assembly method. During assembly, the snap-fit ​​portion on the second end 12 of the first baffle 1 can match the corresponding slot or snap-fit ​​receiving portion on the fourth end 24 of the second baffle 2. A tight connection can be achieved through simple pressing or rotating. This connection method eliminates the need for additional fasteners, simplifying the assembly process and improving assembly efficiency.

[0109] Furthermore, the snap-fit ​​structure has a certain degree of flexibility, which can accommodate minor errors during the assembly process to a certain extent, ensuring the stability and reliability of the connection. At the same time, when it is necessary to disassemble or repair the power supply unit 100, the snap-fit ​​structure facilitates quick release of the connection, reducing maintenance costs and time.

[0110] In some specific embodiments, the first end 11 of the first baffle 1 and the third end 23 of the second baffle 2 are connected by a pin structure, and the first baffle 1 is connected to the second end 12 and the fourth end 24 of the second baffle 2 by a snap-fit ​​structure.

[0111] The pin structure provides a stable initial connection, ensuring that the two baffles 10 do not separate during assembly. The snap-fit ​​structure, on the other hand, further enhances the tightness and reliability of the connection through its quick and easy connection method.

[0112] In some alternative embodiments, combined with Figure 7 - Figure 11 The first baffle 1 has a first locking hole 121 and a first locking protrusion 122 at its second end 12, and the first locking hole 121 and the first locking protrusion 122 are distributed at intervals along the height direction of the battery pack; the second baffle 2 has a second locking hole 241 and a second locking protrusion 242 at its fourth end 24, and the second locking hole 241 and the second locking protrusion 242 are distributed at intervals along the height direction of the battery pack; wherein, the first locking protrusion 122 is engaged in the second locking hole 241, and the second locking protrusion 242 is engaged in the first locking hole 121.

[0113] Optionally, the second end 12 of the first baffle 1 is provided with one or more first locking holes 121 along the height direction of the battery pack. These first locking holes 121 can be constructed as circles, squares or other shapes that facilitate the insertion of the second locking protrusion 242, so as to ensure that the second locking protrusion 242 can be smoothly and securely locked in.

[0114] The second end 12 of the first baffle 1 is provided with one or more first latching protrusions 122 along the height direction of the battery pack. The first latching protrusions 122 correspond to the second latching holes 241, and the first latching protrusions 122 are constructed to match the shape of the second latching holes 241 so that they can be smoothly inserted into the corresponding second latching holes 241 during assembly.

[0115] In some such Figure 7 - Figure 8 In the specific embodiment shown, the second end 12 of the first baffle 1 is provided with a first card hole 121 and a first card protrusion 122 along the height direction of the battery pack.

[0116] The first locking hole 121 and the second locking protrusion 242 (as well as the second buckle and the second locking protrusion 242) are distributed at intervals along the height direction of the battery pack. This means that the connection between the second end 12 of the first baffle 1 and the fourth end 24 of the second baffle 2 is not concentrated at one point, but is distributed along the vertical height direction of the battery pack. This arrangement helps to disperse stress and improve the stability of the connection.

[0117] The first protrusion 122 and the first baffle 1, and the second protrusion 242 and the second baffle 2 can be formed in one step. However, this invention is not limited to this; the first protrusion 122 (second protrusion 242) can also be formed after the first baffle 1 (second baffle 2) has been formed. In this case, the first protrusion 122 and the first baffle 1 (second protrusion 242 and second baffle 2) can be formed after two processing steps. It is understood that regardless of the specific processing order of the first protrusion 122 and the first baffle 1 (second protrusion 242 and second baffle 2), as long as the second end 12 and the first protrusion 122 (fourth end 24 and second protrusion 242) are an integrated structure after the first baffle 1 (second baffle 2) has been fully processed, this is acceptable.

[0118] In some alternative embodiments, combined with Figures 8-9 The first protrusion 122 extends along the height direction of the battery pack, and the second hole 241 is a hole with the same shape as the first protrusion 122. The second hole 241 has a second opening 2411 on one side.

[0119] For example, a columnar first latching protrusion 122 extending along the height direction of the battery pack is provided at the second end 12 of the first baffle 1. This columnar structure not only enables a reliable connection but also allows the first latching protrusion 122 to have a certain radial movement space during assembly. This means that when the first latching protrusion 122 is inserted into the second latching hole 241, even if there are minor positional deviations or assembly errors, they can be adapted and corrected through radial movement, thereby ensuring smooth engagement.

[0120] The second card hole 241 corresponds to the first card protrusion 122. The fourth end 24 of the second baffle 2 is provided with a hole with the same shape as the first card protrusion 122 as the second card hole 241.

[0121] For example, the second locking hole 241 is a cylindrical hole. This cylindrical hole design matches the first locking protrusion 122, providing an effective connection for the first locking protrusion 122.

[0122] The second slot 241 has a second opening 2411 on one side.

[0123] Reference Figure 9 First, the second opening 2411 not only provides a smoother insertion path for the first card protrusion 122.

[0124] Secondly, the second opening 2411 cleverly avoids the connection point between the first latching protrusion 122 and the first baffle 1. This connection point refers to any structural connection or transition area that may exist between the first latching protrusion 122 and the first baffle 1. These connection points may have a certain thickness or size, potentially creating obstacles during assembly. By providing the second opening 2411, it can be ensured that the second latching hole 241 can smoothly avoid these connection points during assembly without being obstructed or damaged. This improves the smoothness of assembly while also protecting the integrity of the first latching protrusion 122 and the first baffle 1.

[0125] Furthermore, the presence of the second opening 2411 enhances the adaptability of the connection. Even with minor assembly errors or changes in component dimensions, the first locking protrusion 122 can still be smoothly inserted and engaged due to the presence of the second opening 2411, thus achieving a good connection.

[0126] Optionally, the second slot 241 and the second opening 2411 are open on at least one side along both sides of the battery pack height direction.

[0127] Therefore, in some designs, the second slot 241 and the second opening 2411 are vertically continuous along the height direction of the battery pack. Or, in some designs... Figure 10In the illustrated design, the second locking hole 241 is open on one side and closed on the other side in the height direction of the battery pack. The closed side serves as a positioning and support, ensuring that the first locking protrusion 122 cannot easily detach once it is inserted. Therefore, the support on the closed side enhances the strength of the connection.

[0128] like Figure 11 As shown, the second protrusion 242 extends along the height direction of the battery pack, and the first hole 121 is a hole with the same shape as the second protrusion 242. The first hole 121 has a first opening 1211 on one side.

[0129] For example, the second protrusion 242 is a column extending along the height direction of the battery pack. This design ensures the stability and support of the connecting components in the vertical direction.

[0130] Matching the second latching protrusion 242 is the first latching hole 121, which is constructed as a cylindrical hole with the same shape as the second latching protrusion 242. This consistency in shape ensures that when the second latching protrusion 242 is inserted into the first latching hole 121, the two can fit tightly together to form a stable mechanical connection. The cylindrical hole also allows for a certain tolerance range during assembly. Even if there are minor dimensional differences or assembly errors, they can be accommodated by the elasticity or deformation of the cylindrical hole, thereby ensuring a smooth connection.

[0131] The first locking hole 121 has a first opening 1211 on one side. Similar to the second opening 2411, the presence of the first opening 1211 gives the first locking hole 121 a certain degree of elasticity during assembly. When the second locking protrusion 242 attempts to insert, even if it encounters slight resistance or deviation, the first opening 1211 can allow for a certain degree of adjustment or deformation, thereby ensuring successful connection and improving the flexibility of the first baffle 1 and the second baffle 2 during assembly. Furthermore, the first opening 1211 can also avoid the connection position between the second locking protrusion 242 and the second baffle 2, improving the smoothness of assembly.

[0132] Optionally, the first slot 121 and the first opening 1211 are open on at least one side along both sides of the battery pack height direction.

[0133] In some designs, the first slot 121 and the first opening 1211 are vertically continuous. Alternatively, in some designs, they are combined... Figure 10 The first locking hole 121 and the first opening 1211 are open on one side and closed on the other. The closed side serves as a positioning and support, ensuring that the second locking protrusion 242 cannot easily fall off once it is inserted. Therefore, the support on the closed side enhances the strength of the connection.

[0134] It is worth noting that in some optional embodiments, both ends of the first baffle and both ends of the second baffle are connected by a pin structure. For example, the first end of the first baffle and the third end of the second baffle are connected by a pin hole-pin, and the second end of the first baffle and the fourth end of the second baffle are connected by a pin hole-pin.

[0135] Alternatively, both ends of the first baffle and both ends of the second baffle may be snap-fitted together. For example, the first end of the first baffle and the third end of the second baffle may be connected by a snap-fit ​​protrusion-snap, and the second end of the first baffle and the fourth end of the second baffle may be connected by a snap-fit ​​protrusion-snap.

[0136] Alternatively, the first end of the first baffle and the third end of the second baffle may simultaneously include pin-hole-pin connections and snap-fit-hole connections, and the second end of the first baffle and the second baffle may simultaneously include pin-hole-pin connections and snap-fit-hole connections. Specifically, between the first end of the first baffle and the third end of the second baffle, a snap-fit ​​can be provided on one end face, while a matching snap-fit ​​hole is provided on the other end face. Pin holes and snap-fits can also be additionally designed on the end face where snap-fits and snap-fit ​​holes have already been provided. Similarly, between the second end of the first baffle and the fourth end of the second baffle, a snap-fit ​​can be provided on one end face, while a matching snap-fit ​​hole is provided on the other end face, and pin holes and snap-fits can be additionally designed on the end face where snap-fits and snap-fit ​​holes have already been provided. By simultaneously employing both snap-fit-hole and pin-hole-pin connection methods, the strength and stability of the connection can be greatly improved. The snap-fit-hole connection provides initial fixation, while the pin-hole-pin connection ensures further reinforcement and stability of the connection. This combination connection method can improve the pressure resistance of the power supply device because it can effectively distribute stress and prevent connection failure.

[0137] According to some embodiments of the present invention, the power supply device 100, such as Figure 2 - Figure 3 As shown, each baffle 10 includes a main body 101 and two sets of arm plates 102. The two sets of arm plates 102 are connected to the two circumferential sides of the main body 101, and each set of arm plates 102 includes at least two arm plates 102 that are spaced apart along the height direction of the battery pack.

[0138] The main body 101 serves as the primary support structure for the baffle 10, connecting and supporting the two sets of arm plates 102 while maintaining the overall stability of the baffle 10. The design of the main body 101 takes into account the effective use of materials, ensuring sufficient strength while avoiding unnecessary material waste through reasonable thickness and shape design.

[0139] Two sets of arm plates 102 are respectively connected to the two circumferential sides of the main body 101, and each set of arm plates 102 includes at least two arm plates 102 that are spaced apart along the height direction of the battery pack. This arrangement of the arm plates 102 not only reduces the amount of material used and lowers the overall weight of the power supply unit 100, but also helps to achieve the goal of lightweighting, which meets the modern electronic devices' pursuit of portability and energy efficiency.

[0140] Moreover, the spacing of each set of arm plates 102 along the height of the battery pack effectively reduces the coverage area of ​​the baffle 10 on the battery pack and increases the heat exchange area between the battery pack and the surrounding environment. This helps the heat generated by the battery pack during operation to dissipate more quickly, reduce the temperature of the battery pack, and improve its working efficiency and safety.

[0141] The arrangement of each set of arm plates 102 along the height direction of the battery pack effectively limits the height of the battery pack. This limiting effect prevents the battery pack from shifting under vibration or impact conditions, protecting the integrity of the internal structure of the battery pack and reducing the impact of the battery pack on other components inside the power supply device 100, thereby improving the reliability and durability of the power supply device 100.

[0142] In some optional embodiments, the two arm plates 102 provided on the first end 11 of the first baffle 1 and the two arm plates 102 provided on the third end 23 of the second baffle 2 are set at different heights along the height direction of the battery pack. This arrangement enables the arm plates 102 of the first end 11 of the first baffle 1 and the arm plates 102 of the third end 23 of the second baffle 2 to be spatially offset from each other when the baffle 10 is flipped, avoiding mutual interference or overlap, thereby ensuring high flexibility in the assembly of the baffle 10.

[0143] It is known that there is a certain angle between the arm plate 102 and the main body 101. The size of this angle can be adjusted according to actual application requirements, such as according to the circumferential shape of the battery pack. By adjusting the angle, the gap between the baffle and the battery pack can be minimized, thereby improving the overall strength of the annular structure.

[0144] According to some embodiments of the present invention, the power supply device 100, such as Figure 2 - Figure 12 As shown, each baffle 10 has a reinforcing structure 103 on the surface opposite to the battery pack.

[0145] In some embodiments, the reinforcing structure 103 is at least one reinforcing rib or at least one frame structure. By providing reinforcing ribs or frame structures, the structural support capacity of the baffle 10 can be strengthened, its overall strength can be improved, and a more stable support effect can be ensured.

[0146] In some alternative embodiments, the design of the reinforcing structure 103 is very flexible and is not limited to the form of a single reinforcing rib or frame, but may include a combination of two or more reinforcing ribs and / or frames.

[0147] First, when the reinforcing structure 103 includes two or more reinforcing ribs, these ribs can be arranged in various forms, such as parallel, intersecting, or in a specific pattern. The reinforcing ribs can be interconnected to form a continuous network structure. This design can more effectively disperse and resist forces and stresses from multiple directions, thereby improving the overall strength and stability of the baffle 10. On the other hand, the reinforcing ribs can also be independent of each other, each forming an independent support path on the surface of the baffle 10. This helps to reduce weight while maintaining a certain level of strength.

[0148] Secondly, when the reinforcing structure 103 includes frames, these frames can be rectangular, circular, polygonal, or other arbitrary shapes. These frames can be evenly distributed on the surface of the baffle 10 or arranged in a specific pattern. The frames can also be interconnected to form a more stable overall structure, providing additional support and protection for the baffle 10. If the frames are independent of each other, they can provide support within their respective areas.

[0149] Both the reinforcing ribs and the frame can be adjusted and optimized in terms of materials, dimensions, shapes, and arrangements according to actual needs to achieve the best reinforcement effect. This diverse reinforcement structure 103 design enables the baffle 10 to better adapt to various complex environments and application scenarios, ensuring its stability and durability.

[0150] In some alternative embodiments, the reinforcing structure 103 is a mesh structure. By setting the mesh structure, the baffle 10 can maintain the necessary support while correspondingly reducing the amount of material used.

[0151] In some alternative embodiments, the mesh in the mesh structure extends through the entire thickness of the baffle 10, forming transparent holes. This design is equivalent to increasing the porosity of the surface of the baffle 10, allowing air to circulate more freely, thereby improving the heat dissipation efficiency of the battery pack, helping to reduce the internal temperature of the battery pack, and extending the service life of the battery pack and other components.

[0152] Alternatively, the mesh in the mesh structure exists on the surface of the baffle 10 away from the battery pack, and does not penetrate its entire thickness. This arrangement ensures that the mesh structure is located only on one side of the baffle 10, serving as a non-penetrating structure that maintains the necessary structural strength while allowing for optimized heat dissipation in specific areas as needed, and avoids the risk of direct exposure to the battery pack.

[0153] Optionally, a reinforcing structure 103 is provided on the main body 101 and / or the arm plate 102. It should be noted that the reinforcing structure 103 provided on the main body 101 and the arm plate 102 may include various forms such as lines, frames or grids. They may be interconnected or independent, and may extend through the entire thickness of the baffle 10 or be located only on one side of its surface.

[0154] To effectively enhance the local support strength in specific areas while controlling costs, the reinforcement structure 103 can employ a flexible density adjustment strategy. Specifically, in critical areas requiring high-strength support, the support density of the reinforcement structure 103 is increased by increasing the number of grid lines or reducing the size of grid cells to enhance the load-bearing capacity and stability of these areas. Conversely, in areas where support strength requirements are lower, the support density of the reinforcement structure 103 is reduced by decreasing the number of grid lines or increasing the size of grid cells to reduce material usage and thus achieve cost control.

[0155] like Figure 2 As shown, the power supply device 100 according to some embodiments of the present invention further includes a bracket 20. The bracket 20 is connected to the top of at least one baffle 10.

[0156] Optionally, the bracket 20 and the baffle 10 are connected by a limiting structure or limiting member.

[0157] In this way, the bracket 20 can provide a certain constraint on the baffle 10, effectively preventing the baffle 10 from shifting due to external forces, thereby enhancing the overall structural strength of the power supply device 100 and making it more adaptable to more complex working environments.

[0158] Specifically, the limiting structure can be a magnetic limiting structure, a fastening component limiting structure, etc. The limiting element can be a screw, pin, etc. The limiting structure and limiting element can adopt known solutions in the prior art. The limiting structure and limiting element themselves are not the core points of this application, so they will not be described in detail here.

[0159] In some alternative embodiments, the power supply device 100 also includes a control board 30, which is mounted on the bracket 20.

[0160] The bracket 20 is used to support the control board 30 and to stabilize the control board 30.

[0161] As part of the power supply unit 100, the control board 30 is responsible for monitoring and regulating the operation of the power supply unit 100. Therefore, the control board 30 integrates various electronic components and circuits to realize current and voltage control, fault detection, and protection mechanisms. By mounting the control board 30 on the bracket 20, the control board 30 can perform its tasks stably, safely, and reliably, ensuring that the power supply unit 100 can work efficiently and stably.

[0162] Optionally, a limiting structure is provided between the control board 30 and the bracket 20. The control board 30 is mounted on the bracket 20. By using the limiting structure, the accidental movement of the control board 30 on the bracket 20 can be effectively prevented, ensuring that the control board 30 is in the correct installation position, reducing the displacement of the control board 30 caused by vibration or impact, and thus improving the reliability of the power supply device 100.

[0163] In some embodiments, combined with Figure 3 Each baffle 10 has a connection hole 104 on its top, and the bracket 20 is connected to the connection hole 104 by fasteners.

[0164] Specifically, a connection hole 104 is provided on the top of the baffle 10 to provide installation space for the connection of fasteners. When connecting the bracket 20 and the baffle 10, the bracket 20 is first aligned with the connection hole 104, and then a suitable fastener is passed through the connection hole 104 to fix the baffle 10 and the bracket 20.

[0165] Fasteners can be bolts, screws, etc. Optionally, mounting washers are also provided on the bracket 20 and / or the baffle 10 to increase friction, thereby improving the fastening effect and preventing loosening.

[0166] The size and shape of the fastener are adapted to the connection hole 104 to ensure the connection between the two.

[0167] However, this utility model also includes another power supply device structure. In the structure of the power supply device in this embodiment, the bracket 20 and the baffle 10 are integrally formed. By setting the integrally formed bracket and baffle, the structural stability of the power supply device can be enhanced, the battery pack can be effectively fixed, and cost savings can be achieved by reducing the number of parts and assembly steps.

[0168] In some optional embodiments, the power supply device further includes a base 40. The base 40 is connected to the bottom of at least one baffle. The base 40 serves to provide stable support and enhance the overall structural strength of the power supply device.

[0169] Optionally, the base 40 and the baffle can be connected in various ways. They can be securely connected using fasteners such as screws and nuts to ensure structural stability and durability; or they can be connected via a snap-fit ​​design for quick installation and disassembly, facilitating maintenance and replacement. Alternatively, a receiving groove can be provided on the base 40 to prevent the battery pack from shaking. The edge of the baffle can fit tightly against the wall of the receiving groove, effectively preventing displacement or vibration of the battery pack during use, thus ensuring the safety and reliability of the power supply device.

[0170] The electrical equipment according to a second aspect of the present invention includes a power supply device 100 according to a first aspect of the present invention.

[0171] By setting up a stable and reliable power supply device 100, the reliability of electrical equipment is improved.

[0172] In some optional embodiments, the electrical equipment is applied in a vehicle. It is worth noting that the vehicle in this application can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The vehicle is equipped with electrical equipment, which can be located at the bottom, front, or rear of the vehicle. The electrical equipment can be used to supply power to the vehicle; for example, it can serve as the vehicle's operating power source. The vehicle may also include a controller and a motor. The controller is used to control the electrical equipment to supply power to the motor, for example, for the vehicle's starting, navigation, and driving power needs. In some embodiments of this application, the electrical equipment can not only serve as the vehicle's operating power source but also as the vehicle's drive power source, replacing or partially replacing gasoline or natural gas to provide driving power to the vehicle.

It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.
