Description

Technical Field

[0001] This application relates to the field of batteries, and in particular to an energy storage device and an electrical appliance. Background Technology

[0002] Battery units are typically assembled into the power cabinet using a pushing method. During the pushing process, the battery unit's casing is prone to friction and collision with the power cabinet, causing the casing to deform and affecting the individual battery cells inside, thus reducing the operational stability of the individual battery cells. Utility Model Content

[0003] In view of the above problems, this application provides an energy storage device and an electrical device that can reduce the risk of deformation of the battery device casing during assembly and improve the structural stability of the battery device.

[0004] In a first aspect, this application provides an energy storage device, including a battery assembly, a mounting frame, a connecting assembly, and a buffer. The battery assembly includes a housing and individual battery cells disposed within the housing. The mounting frame has a slide rail extending along a first direction, and the connecting assembly is connected to the housing and slidably connected to the slide rail. The buffer is disposed at the end of the slide rail along the first direction and is capable of extending and retracting along the first direction. The connecting assembly is capable of sliding within the slide rail along the first direction and moving the battery assembly relative to the mounting frame along the first direction, while the buffer reduces the impact between the battery assembly and the mounting frame.

[0005] In the technical solution of this application embodiment, the battery device is used to provide electrical energy to the equipment. The casing of the battery device protects the individual battery cells to improve their operational stability. A mounting bracket is provided to install the battery device in a preset position, facilitating the movement of the battery device and the connection of related electrical equipment. The mounting bracket is equipped with a slide rail, and the connecting component cooperates with the slide rail to form a sliding connection between the battery device and the mounting bracket, facilitating the assembly of the battery device into the mounting bracket. In particular, a buffer is provided at the end of the slide rail to form a buffer between the battery casing and the mounting bracket, reducing the impact of the collision between the casing and the mounting bracket, minimizing damage to the casing, improving the structural integrity of the casing, and thus improving the operational stability of the individual battery cells.

[0006] In some embodiments, the buffer includes at least one of a rubber block, an airbag, and a polyurethane block. The aforementioned buffer is capable of contracting along a first direction when the housing contacts the mounting frame, simultaneously exerting a reaction force on both the housing and the mounting frame, reducing the impact force of their collision, and effectively buffering the damage caused by impact and friction during movement.

[0007] In some embodiments, the buffer includes an elastic element capable of stretching and contracting along a first direction. The elastic element slows the movement of the housing along the slide rail, allowing the battery assembly to be smoothly installed into place.

[0008] In some embodiments, the buffer further includes a connecting block connected to the end of the elastic member facing the connecting assembly, the connecting block being slidably connected to the slide rail. The connecting block increases the contact area between the elastic member and the housing, reduces the pressure between the housing and the elastic member, improves the integrity of the housing surface, and reduces the risk of deformation of the elastic member.

[0009] In some embodiments, two connecting components are provided, positioned on opposite sides of the housing along a second direction that intersects with the first direction. Two slide rails are also provided, with the space between them used to accommodate the battery device. In the above structure, by providing two connecting components, the force balance during battery assembly is improved, thus enhancing the structural stability of the battery device.

[0010] In some embodiments, the slide rail includes a top plate and a bottom plate disposed opposite each other along a third direction, and a side plate connected between the top plate and the bottom wall. The top plate, side plate, and bottom plate enclose a receiving space for accommodating the connecting assembly. This structure, with the top plate, side plate, and bottom plate surrounding the connecting assembly, restricts and guides the movement of the connecting assembly from two directions, improving the stability and positional accuracy of the battery assembly process.

[0011] In some embodiments, the top plate is provided with a first sliding groove extending in a first direction, and the connecting block has a first protrusion on one side surface facing the first sliding groove. The first protrusion extends into the first sliding groove and moves within the first sliding groove to slide the connecting block and the slide rail. The above structure, by providing the first sliding groove and the first protrusion, restricts the movement direction of the connecting block to the first direction, reducing the risk of the connecting block detaching from the receiving space.

[0012] In some embodiments, a buffer pad is further provided on one side of the enclosure along the first direction. This structure provides buffering between the enclosure and the mounting frame, further enhancing the structural stability of the enclosure.

[0013] In some embodiments, two guide rails arranged opposite each other along a second direction form a bracket, and a fixing frame is provided with multiple brackets. The multiple brackets are arranged sequentially along a third direction, which intersects the plane containing the first direction and the second direction. In the above structure, by providing multiple brackets, the number of battery devices in the energy storage device is increased, the energy density of the energy storage device is improved, and the installation efficiency and positional accuracy of the battery devices are also improved.

[0014] Secondly, this application provides an electrical device that includes the energy storage device described in the above embodiments, the energy storage device being used to provide electrical energy.

[0038] Battery units are used to provide electrical power to equipment. To increase voltage and energy storage capacity, multiple battery units can be installed in a fixed frame and interconnected to form an energy storage device to power the equipment. Battery units are relatively large and heavy. During installation, a robotic arm or hoisting equipment is used to move the battery units to the opening side of the fixed frame and push them into the frame from the opening. This pushing process involves a certain amount of inertia, which can easily cause impact and friction between the battery unit's casing and the fixed frame, potentially damaging the casing.

[0039] Based on the above, this application provides an energy storage device. The battery unit provides electrical energy to the equipment, and the housing within the battery unit protects the individual battery cells to improve their operational stability. A mounting bracket is provided to install the battery unit in a preset position, facilitating the movement of the battery unit and the connection of related electrical equipment. The mounting bracket is equipped with a slide rail, and a connecting component cooperates with the slide rail to form a sliding connection between the battery unit and the mounting bracket, facilitating the assembly of the battery unit into the mounting bracket. In particular, a buffer is provided at the end of the slide rail to create a buffer between the battery housing and the mounting bracket, reducing the impact of the collision between the housing and the bracket, minimizing damage to the housing, improving the structural integrity of the housing, and thus enhancing the operational stability of the individual battery cells.

[0040] Please refer to the reference. Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of an energy storage device provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of a battery device provided in some embodiments of this application. Figure 3 This is a schematic diagram of the structure of a battery cell provided in some embodiments of this application. Figure 4 This is a schematic diagram of the structure of a buffer provided in some embodiments of this application.

[0041] As shown in the figure, the energy storage device 1 includes a battery device 2, a mounting frame 3, a connecting assembly 4, and a buffer 7. The battery device 2 includes a housing 5 and individual battery cells 6 disposed within the housing 5. The mounting frame 3 is provided with a slide rail 301 extending along a first direction X. The connecting assembly 4 is connected to the housing 5 and is slidably connected to the slide rail 301. The buffer 7 is disposed at the end of the slide rail 301 along the first direction X and is capable of extending and retracting along the first direction X. The connecting assembly 4 can slide within the slide rail 301 along the first direction X and drive the battery device 2 to move relative to the mounting frame 3 along the first direction X. The buffer 7 is used to reduce the impact between the battery device 2 and the mounting frame 3.

[0042] Battery assembly 2 typically includes a housing 5 and individual battery cells 6. The housing 5 houses the individual battery cells 6 and can have various structures. The housing 5 has a cavity for accommodating the individual battery cells 6. In battery assembly 2, there can be one or more individual battery cells 6. If there are multiple individual battery cells 6, they can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple individual battery cells 6 are connected in both series and parallel connections. Multiple individual battery cells 6 can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of the multiple individual battery cells 6 is housed within the housing 5.

[0043] The battery cell 6 can be the smallest unit constituting the battery device 2. For example, the battery cell 6 includes a housing 20 and an electrode assembly 10 housed within the housing 20. The electrode assembly 10 includes a positive electrode and a negative electrode. During the charging and discharging process of the battery cell 6, active ions (e.g., lithium ions) repeatedly insert and extract between the positive and negative electrodes.

[0044] For example, the mounting bracket 3 is a cabinet structure with an opening, through which the battery device 2 can enter the mounting bracket 3. The mounting bracket 3 includes two opposing vertical plates 302 and a connecting plate 303 connecting the two vertical plates 302, the connecting plate 303 being opposite to the opening. The first direction X can be the direction from the outlet to the connecting plate 303. The mounting bracket 3 may also include two opposing horizontal plates, with the vertical plates 302 and the connecting plate 303 connected between the two horizontal plates. The above structure encloses and forms a stable support structure.

[0045] The slide rail 301 is a strip-shaped structure connected to two vertical plates 302, which can accommodate the movement of the connecting component 4. The connecting component 4 can be a block-shaped structure connected to the housing 5. The connecting component 4 can form a fixed connection with the side of the housing 5, such as by welding or bonding, to improve the stability of the battery device 2 during movement.

[0046] The buffer 7 is located inside the fixing frame 3. For example, the buffer 7 can be positioned close to the connecting plate 303. During movement, the housing 5 of the battery device 2 first contacts the buffer 7. The buffer 7 contracts along the first direction X and applies a reaction force to reduce its movement speed towards the connecting plate 303 until the relative movement completely stops. This process effectively reduces the moving speed of the battery device 2 and reduces friction and deformation on the surface of the housing 5.

[0047] In the technical solution of this application embodiment, the battery device 2 is used to provide power to the equipment. The housing 5 in the battery device 2 protects the battery cells 6 to improve the operational stability of the battery cells 6. A fixing frame 3 is provided to install the battery device 2 in a preset position, which facilitates the movement of the battery device 2 and the connection of related electrical equipment. The fixing frame 3 is provided with a slide rail 301. The connecting component 4 cooperates with the slide rail 301 to form a sliding connection between the battery device 2 and the fixing frame 3, which facilitates the assembly of the battery device 2 into the fixing frame 3. In particular, a buffer 7 is provided at the end of the slide rail 301 to form a buffer between the battery housing 5 and the fixing frame 3, reduce the impact of the housing 5 colliding with the fixing frame 3, reduce the damage to the housing 5, improve the structural integrity of the housing 5, and thus improve the operational stability of the battery cells 6.

[0048] like Figure 5 As shown, in some embodiments of this application, the buffer 7 includes at least one of a rubber block, an airbag, and a polyurethane block.

[0049] Rubber is used in the cushioning component 7 due to its good elasticity and wear resistance, and rubber material is inexpensive and readily available. The rubber block can absorb and disperse impact force, protecting the housing 5 and the fixing frame 3 from damage.

[0050] The airbag buffer 7 is typically made of a flexible material, and, for example, is formed by filling a spherical bladder with gas. Upon impact, the airbag can compress and absorb energy, thus mitigating the impact force. An advantage of airbags is that they can be adjusted as needed to accommodate different impact forces and space requirements.

[0051] Polyurethane is a high-performance material with excellent wear resistance, elasticity, and strength. As a cushioning component, the polyurethane block can withstand significant impact forces while maintaining a low deformation rate, thus preserving its cushioning effect over a long period.

[0052] The aforementioned buffer 7 can retract along the first direction X when the housing 5 contacts the fixed frame 3, and at the same time exert a reaction force on the housing 5 and the fixed frame 3, reducing the impact force of the collision between the two and effectively buffering the impact and friction caused by the movement process.

[0053] like Figure 6 As shown, in some embodiments of this application, the buffer 7 includes an elastic element 701, which is capable of extending and retracting along a first direction X. For example, the elastic element 701 can be a leaf spring, a torsion bar spring, etc.

[0054] By setting the elastic element 701, the speed at which the housing 5 moves along the slide rail 301 can be slowed down, so that the battery device 2 can be smoothly assembled into place.

[0055] like Figure 7 as well as Figure 8 As shown, in some embodiments of this application, the buffer 7 further includes a connecting block 702 connected to one end of the elastic member 701 facing the connecting assembly 4, and the connecting block 702 is slidably connected to the slide rail 301.

[0056] The design of the connecting block 702 increases the contact area between the elastic element 701 and the housing 5, which reduces the pressure per unit area and helps protect the surface of the housing 5 from damage caused by excessive pressure. The reduced pressure means that when the housing 5 is subjected to the reaction force of the elastic element 701, the stress distribution on its surface is more uniform, thus reducing the risk of breakage due to localized stress concentration. By reducing pressure and dispersing stress, the connecting block 702 helps maintain the integrity of the housing 5 surface, reducing deformation or cracks caused by long-term stress. The increased contact area also means that the elastic element 701 will deform less when subjected to pressure from the housing 5, thereby extending the service life of the elastic element 701.

[0057] The sliding connection between the connecting block 702 and the slide rail 301 allows the housing 5 to slide smoothly and steadily along the slide rail 301 during movement. This not only improves the moving efficiency of the housing 5 but also reduces noise and wear caused by friction.

[0058] Optionally, the connecting block 702 can be hexahedral, cylindrical, or other shapes. By adjusting the size and shape of the connecting block 702, it can be adapted to boxes 5 of different sizes and shapes, thus improving the versatility of the buffer 7.

[0059] Therefore, the connection block 702 increases the contact area between the elastic element 701 and the housing 5, reduces the pressure between the housing 5 and the elastic element 701, improves the integrity of the surface of the housing 5, and reduces the risk of deformation of the elastic element 701.

[0060] In some embodiments of this application, two connecting components 4 are provided, and the two connecting components 4 are provided on both sides of the housing 5 along the second direction Y, the second direction Y intersects with the first direction X, and two slide rails 301 are provided accordingly, and the space between the two slide rails 301 is used to accommodate the battery device 2.

[0061] For example, the first direction X is the width direction of the box 5, and the second direction Y is the length direction of the box 5.

[0062] The two connecting components 4 are positioned on both sides of the housing 5 along the second direction Y. During assembly, the battery device 2 receives balanced support from both sides, preventing tilting or twisting caused by unilateral force. Corresponding to the two connecting components 4, two slide rails 301 are provided. The space between these two slide rails 301 is precisely designed to accommodate the battery device 2, allowing it to slide smoothly and steadily along the slide rails 301. By providing two connecting components 4 and two slide rails 301, the battery device 2 receives balanced reaction forces from both sides during assembly. This balanced force helps reduce vibration and shaking of the battery device 2 during assembly, improving the accuracy and stability of the assembly.

[0063] Furthermore, the combined design of the two connecting components 4 and the two slide rails 301 not only enhances the connection strength between the battery device 2 and the housing 5, but also improves the stability of the entire structure. This design ensures that the battery device 2 can be firmly fixed inside the housing 5 after assembly, preventing it from loosening or falling off.

[0064] In the above structure, by setting two connecting components 4, the force balance during the assembly process of the battery device 2 is improved, and the stability of the battery device 2 structure is improved.

[0065] like Figure 6As shown, in some embodiments of this application, the slide rail 301 includes a top plate 304 and a bottom plate 305 disposed opposite each other along a third direction Z, and a side plate 306 connected between the top plate 304 and the bottom wall. The top plate 304, the side plate 306, and the bottom plate 305 enclose a receiving space for accommodating the connecting assembly 4. The top plate 304, the bottom plate 305, and the side plate 306 have equal dimensions along the first direction X, and the three together form a structure with a cross-section similar to a C shape.

[0066] For example, the third direction Z is the thickness direction of the battery device 2. The top plate 304 and the bottom plate 305 restrict the movement of the battery device 2 along the third direction Z. The side plate 306 restricts the movement of the battery device 2 along the second direction Y.

[0067] The above structure, with a top plate 304, side plate 306 and bottom plate 305 surrounding the connecting component 4, restricts and guides the movement of the connecting component 4 from two directions, improving the stability and positional accuracy of the battery device 2 assembly process.

[0068] like Figure 6 as well as Figure 8 As shown, in some embodiments of this application, the top plate 304 is provided with a first sliding groove 307 extending along the first direction X, and the connecting block 702 is provided with a first protrusion 703 on one side surface facing the first sliding groove 307. The first protrusion 703 extends into the first sliding groove 307 and moves within the first sliding groove 307 to slide the connecting block 702 and the slide rail 301.

[0069] For example, the sliding groove is a through groove that extends along the thickness direction of the top plate 304. The sliding groove is provided on the top plate 304 so that it can be effectively connected with the first protrusion 703 and the first protrusion 703 provides space and path for movement.

[0070] Through the cooperation of the first sliding groove 307 and the first protrusion 703, the movement of the connecting block 702 is strictly limited in the first direction X. This limitation ensures that the connecting block 702 will not deviate from the predetermined path during assembly or movement, thereby improving the accuracy and stability of assembly. At the same time, since the first protrusion 703 is confined within the first sliding groove 307, the movement of the connecting block 702 in other directions perpendicular to the first direction X is also effectively prevented, which greatly reduces the risk of the connecting block 702 falling out of the receiving space.

[0071] The above structure, by setting the first sliding groove 307 and the first protrusion 703, restricts the movement direction of the connecting block 702 to the first direction X, reducing the risk of the connecting block 702 falling out of the receiving space.

[0072] In some alternative embodiments, the base plate 305 is provided with a second sliding groove extending along the first direction X, and the connecting block 702 has a second protrusion on one side surface facing the second sliding groove. The second protrusion extends into the second sliding groove and moves within it to slidably connect the connecting block 702 to the slide rail 301. This structure further improves the accuracy and stability of assembly, reduces maintenance costs, and enhances the safety of the assembly process.

[0073] like Figure 9 As shown, in some embodiments of this application, the housing 5 is further provided with a buffer pad 704 on one side along the first direction X.

[0074] The buffer pad 704 is made of a material with a certain degree of elasticity and wear resistance, such as rubber or polyurethane. When the housing 5 comes into contact with the mounting frame 3, the buffer pad 704 can absorb and disperse the impact force, reducing the vibration and impact on the housing 5, thereby protecting the structure and internal components of the housing 5 from damage. The buffer pad 704 not only provides additional support for the housing 5, but also enhances the connection stability between the housing 5 and the mounting frame 3 through its elasticity and wear resistance. This stability helps reduce the shaking and displacement of the housing 5 due to vibration or impact during transportation or use, further improving the overall structural stability of the housing 5.

[0075] By introducing the cushioning pad 704, the contact between the box 5 and the mounting frame 3 becomes more uniform and stable. During transportation or use, even if bumps or vibrations occur, the cushioning pad 704 can effectively absorb and disperse these forces, protecting the structural integrity of the box 5. Furthermore, the application of the cushioning pad 704 reduces the risk of damage to the box 5 due to vibration or impact, ensuring the safety and integrity of the items inside the box 5.

[0076] The aforementioned structure provides a buffer between the housing 5 and the fixing frame 3, further enhancing the structural stability of the housing 5.

[0077] like Figure 1 As shown, in some embodiments of this application, two guide rails arranged opposite each other along the second direction Y form a bracket, and the fixed frame 3 is provided with multiple brackets. The multiple brackets are arranged sequentially along the third direction Z, and the third direction Z intersects with the plane containing the first direction X and the second direction Y.

[0078] In the above structure, by setting multiple brackets, the number of battery devices 2 in the energy storage device is increased, the energy density of the energy storage device 1 is improved, and the installation efficiency and position accuracy of the battery devices 2 are also improved.

[0079] In some alternative embodiments, the energy storage device 1 includes a battery device 2, a mounting frame 3, a connecting assembly 4, and a buffer 7. The battery device 2 includes a housing 5 and individual battery cells 6 disposed within the housing 5. The mounting frame 3 has a slide rail 301 extending along a first direction X. The connecting assembly 4 is connected to the housing 5 and is slidably connected to the slide rail 301. The buffer 7 is located at the end of the slide rail 301 along the first direction X and is capable of extending and retracting along the first direction X. The connecting assembly 4 can slide within the slide rail 301 along the first direction X and drive the battery device 2 to move relative to the mounting frame 3 along the first direction X. The buffer 7 is used to reduce the impact between the battery device 2 and the mounting frame 3. The buffer 7 is a torsion bar spring that extends and retracts along the first direction X. The buffer 7 also includes a connecting block 702 connected to the end of the elastic member 701 facing the connecting assembly 4, and the connecting block 702 is slidably connected to the slide rail 301. Two connecting components 4 are provided, positioned on both sides of the housing 5 along the second direction Y, which intersects with the first direction X. Two corresponding slide rails 301 are provided, with the space between them accommodating the battery device 2. Each slide rail 301 includes a top plate 304 and a bottom plate 305 positioned opposite each other along the third direction Z, and a side plate 306 connecting the top plate 304 and the bottom wall. The top plate 304 has a first sliding groove 307 extending along the first direction X. A connecting block 702 has a first protrusion 703 on its surface facing the first sliding groove 307. The first protrusion 703 extends into and moves within the first sliding groove 307, thereby slidably connecting the connecting block 702 to the slide rail 301. Two guide rails positioned opposite each other along the second direction Y form a bracket. Multiple brackets are provided on the fixing frame 3, arranged sequentially along the third direction Z, which intersects with the plane containing the first direction X and the second direction Y.

[0080] This application also provides an electrical device including the energy storage device 1 described in the above embodiments, which provides electrical energy. A battery device 2 provides electrical energy to the device, and the housing 5 in the battery device 2 protects the individual battery cells 6 to improve their operational stability.
