Description

Technical Field

[0001] This utility model relates to the field of battery box design technology, specifically to a battery box and a battery having the same. Background Technology

[0002] In the field of battery box design, single-layer module structures are currently the dominant form. However, in equipment such as forklifts, pallet trucks, and tractors, where installation space is limited but vertical space is relatively ample, double-layer module battery box designs are particularly crucial. Currently, the industry offers a variety of double-layer module battery box design solutions: some use module end plates and long screws or other connectors to tightly connect the upper and lower modules; others first create an external frame to securely position the two modules before fixing the frame as a whole; still others assemble a double-layer bracket on the battery box first, and then fix the modules layer by layer. Although these methods each have their own advantages, they generally suffer from large space requirements, cumbersome installation processes, and relatively complex debugging and maintenance during subsequent use.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a battery housing and a battery having therein, so as to at least solve the problem of large space requirements when installing double-layer modules in the prior art.

[0006] Furthermore, the support assembly has a disassembled position that allows it to move along a first direction so that at least a portion of the support assembly is located outside the receiving cavity.

[0007] Furthermore, the housing includes a main shell and a side plate. The side plate is located on one side of the main shell along the first direction. The side plate is detachably connected to the main shell. A groove is formed on the side of the main shell near the side plate. The groove depth direction is perpendicular to the first direction. When the side plate is detached from the main shell, the support assembly enters and exits the receiving cavity through the groove.

[0008] Furthermore, the first end of the support base is connected to the housing, and the second end of the support base extends toward the center of the receiving cavity. The support base has a limiting groove, and the extending direction of the limiting groove is parallel to the extending direction of the second end of the support base. When the support assembly is in the working position, at least a portion of the support assembly is located in the limiting groove.

[0009] Furthermore, the support assembly includes: a support plate, which is movably disposed relative to the housing; and a limiting beam, one end of which is connected to the support plate, and the other end of which protrudes from the support plate toward the support seat. When the support assembly is in the working position, the limiting beam is engaged in the limiting groove.

[0010] Furthermore, the support assembly is provided with a module fixing beam. When the support assembly is in the working position, the module fixing beam forms a connecting part for connecting the single-layer battery module. The module fixing beam and the limiting beam are respectively provided on both sides of the support plate.

[0011] Furthermore, when the limiting beam is engaged with the limiting groove, the bottom plane of the support plate abuts against the top plane of the support seat.

[0012] Furthermore, the support assembly also includes a locking member, which has a locking position for locking the limiting beam into the limiting groove when the limiting beam is engaged with the limiting groove, and an unlocking position for releasing the limiting beam from the limiting groove.

[0013] Furthermore, the first direction is the length direction of the box, and / or the second direction is the height direction of the box.

[0014] According to one aspect of the present invention, a battery is provided, including a battery housing, wherein the battery housing is the aforementioned battery housing.

[0015] By applying the technical solution of this utility model, the support component is configured to be movable relative to the housing, and when the support component is in the working position, it can divide the receiving cavity to construct an installation space for accommodating a single-layer battery module. This solves the problem of supporting and fixing multi-layer battery modules within a limited space, without occupying a large area.

[0031] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0032] Combination Figures 1 to 4 As shown, according to a specific embodiment of this application, a battery housing is provided, including: a housing 10, the housing 10 having an internal receiving cavity 11, and at least one support seat 3 disposed on the housing 10; a support assembly 20, the support assembly 20 being detachably connected to the housing 10, the support assembly 20 being movably disposed relative to the housing 10 along a first direction, the support assembly 20 having a working position completely located within the receiving cavity 11, the support assembly 20 being connected to at least one support seat 3 when in the working position, and the support assembly 20 dividing the receiving cavity 11 into at least two sub-cavities 111 along a second direction, wherein at least one sub-cavity 111 forms an installation space for accommodating a single-layer battery module.

[0033] By applying the technical solution of this utility model, the support component 20 is configured to be movable relative to the housing 10, and when the support component 20 is in the working position, it can divide the receiving cavity 11 to construct an installation space for accommodating a single-layer battery module. This solves the problem of supporting and fixing multi-layer battery modules in a limited space without occupying a large amount of space, and effectively improves installation efficiency and simplifies maintenance procedures. The technical solution of this application effectively solves the problem of large space requirements when installing double-layer modules in the battery housing in the prior art.

[0034] By dividing the housing into at least two sub-cavities, a double-layer battery module arrangement can be achieved within a limited installation space, making full use of the vertical space of the battery box, thereby significantly increasing the energy storage capacity of the battery box without increasing the overall volume.

[0035] The support assembly 20 is movably disposed relative to the housing 10 along a first direction, meaning that the position of the support assembly can be adjusted as needed when installing or replacing battery modules. This design not only facilitates the quick installation and removal of battery modules but also allows for flexible adjustments based on different battery sizes or quantities, enhancing the scalability and adaptability of the battery housing.

[0036] When the support assembly 20 is in the working position, its detachable connection to the support base 3 ensures that the upper battery module can be inspected or replaced independently of the lower module. This avoids the need to disassemble the entire battery box or the lower battery module to maintain the upper module, greatly improving maintenance efficiency and reducing maintenance costs.

[0037] The connection between the support components and the support base, as well as its partitioning of the housing cavity, helps enhance the structural stability of the entire battery box, ensuring the safety and reliability of the battery during transportation and use. Layered installation of battery modules allows for a more rational arrangement of the battery thermal management system, such as cooling channels or heat sinks, ensuring effective cooling of each battery module layer, thereby improving battery performance and lifespan.

[0038] By using detachable support components and a simple installation mechanism, the need for additional frames or fixing structures is reduced, manufacturing costs are lowered, and production efficiency is improved.

[0039] Furthermore, the support assembly 20 has a disassembled position that allows it to move along a first direction so that at least a portion of the support assembly 20 is located outside the receiving cavity 11. This arrangement significantly improves maintenance efficiency and reduces maintenance costs.

[0040] Furthermore, the housing 10 includes a main housing 5 and a side plate 1. The side plate 1 is located on one side of the main housing 5 along the first direction. The side plate 1 is detachably connected to the main housing 5. A groove 30 is formed on the side of the main housing 5 near the side plate 1. The groove depth direction of the groove 30 is perpendicular to the first direction. When the side plate 1 is detached from the main housing 5, the support assembly 20 enters and exits the receiving cavity 11 through the groove 30.

[0041] The slot design allows the support components to enter or exit the receiving cavity along the first direction without removing the side panels. This means that the installation and removal of the upper battery module can be carried out quickly without disassembling the entire battery housing, greatly simplifying the maintenance process and saving time and costs.

[0042] The slot design provides the necessary passage for the installation and removal of support components without increasing the overall size of the enclosure. This not only improves space utilization but also maintains the compactness of the battery enclosure, which is especially important for applications with limited space, such as forklifts and pallet trucks.

[0043] Because the support components can be operated directly through the slots, direct intervention in the internal structure of the battery housing is reduced, minimizing the impact on other components and the risk of potential damage during maintenance. Maintenance personnel can focus solely on the upper battery modules without having to deal with the complexities of the entire system, making the maintenance process simpler and safer.

[0044] The groove depth is perpendicular to the first direction, which allows for greater flexibility in the installation position and angle of the support component. Depending on different application scenarios and requirements, the support component can be adjusted to fit the groove, achieving a more optimized layout and thus better adapting to different battery module sizes and shapes.

[0045] In emergency situations, such as battery overheating or short circuits, the upper battery module can be quickly removed through the slot, preventing potential thermal runaway or electrical risks from spreading to the entire battery box and enhancing the system's safety performance.

[0046] The presence of the slot makes it easier to inspect and replace the upper battery module inside the battery box. This facilitates future upgrades in battery technology and the replacement of battery modules, ensuring that the equipment can keep pace with the times and maintain optimal performance.

[0047] In the technical solution of this application, a slot is cut into the side of the battery box body, allowing for quick assembly and disassembly of the upper module support plate. A support base is welded onto the battery box body, and the support base and support plate are fixed together by side threads, improving installation efficiency and ease of maintenance. This application solves the problems of supporting and fixing battery modules in a limited space within a double-layer battery box, as well as the efficiency and convenience of the inspection and maintenance process for the upper and lower modules in a double-layer battery box. Through the above technical solution, installation efficiency is improved, the battery box inspection process is greatly simplified, and maintenance efficiency and convenience are enhanced; at the same time, the safety and stability of the battery module in the double-layer battery box are ensured, enabling rapid maintenance even in confined spaces.

[0048] Furthermore, the first end of the support base 3 is connected to the housing 10, and the second end of the support base 3 extends toward the middle of the receiving cavity 11. The support base 3 has a limiting groove 40, and the extending direction of the limiting groove 40 is parallel to the extending direction of the second end of the support base 3. When the support assembly 20 is in the working position, at least a portion of the support assembly 20 is located in the limiting groove 40.

[0049] The limiting groove ensures that the support components are precisely installed in the intended position, preventing offset or shaking during installation. The second end of the support base extends to the center of the receiving cavity, providing more stable support for the upper battery module, reducing vibration during transportation or operation, and ensuring the safety and stability of the battery module.

[0050] During installation, the support components can be quickly positioned by sliding into the limiting slots, eliminating the need for complex alignment or adjustments and significantly improving installation speed. This design reduces labor and time costs during installation, with its advantages being particularly pronounced in mass production or on-site installation.

[0051] When the upper battery module needs to be disassembled or replaced, the support assembly can slide directly out of the limiting groove without disassembling the entire support structure or housing. This simplifies the disassembly process, reduces maintenance difficulty, and saves maintenance time. The extension design of the support base towards the center of the receiving cavity helps to optimize the internal space of the battery housing, reducing unnecessary gaps and improving the overall structural compactness. This is especially important for space-constrained applications, such as forklifts and pallet trucks, as it maximizes the use of limited space.

[0052] This support design facilitates the placement of heat dissipation components or channels within the battery housing, such as fans, heat sinks, or coolant lines. Particularly, the sides of the limiting slot provide a direct heat dissipation path for the battery module, improving thermal management and extending battery life. The limiting slot design also makes the assembly and disassembly of the support components and the upper battery module more convenient. Especially when rapid replacement of damaged battery modules is required, this design significantly improves work efficiency and reduces downtime due to maintenance.

[0053] Optionally, by adjusting the size and position of the limiting groove, it can accommodate battery modules of different sizes or shapes, enhancing the versatility and adaptability of the battery box design and reducing the need for design modifications due to changes in battery module size.

[0054] Furthermore, the support assembly 20 includes: a support plate 4, which is movably disposed relative to the housing 10; and a limiting beam 50, one end of which is connected to the support plate 4, and the other end of which protrudes from the support plate 4 toward the support seat 3. When the support assembly 20 is in the working position, the limiting beam 50 is engaged in the limiting groove 40.

[0055] The limiting beam engages within the limiting groove, ensuring that the support plate can be precisely positioned on the support base during installation, preventing positional shifts during the installation process, and providing a stable connection to guarantee the stability and safety of the upper battery module.

[0056] The design of the limiting beam and limiting groove makes the installation and disassembly of the support plate very quick and simple. Simply slide the support plate along the limiting groove for positioning and initial fixation. During disassembly, the support plate can easily slide out of the limiting groove, eliminating the need for complex disassembly steps and greatly improving maintenance efficiency. The limiting beam design allows the support plate to fit snugly against the internal structure of the battery box, reducing unnecessary space waste, optimizing the internal space layout of the battery box, and helping to maximize the number of battery modules that can be installed within a limited space.

[0057] Because the limiting beam can fit tightly with the support base, this design helps to form a stable heat conduction interface between the support plate and the housing, which is conducive to the effective operation of the internal thermal management system of the battery housing, thereby improving battery efficiency and life.

[0058] Furthermore, a module fixing beam 60 is provided on the support component 20. When the support component 20 is in the working position, the module fixing beam 60 forms a connecting part for connecting the single-layer battery module. The module fixing beam 60 and the limiting beam 50 are respectively provided on both sides of the support plate 4.

[0059] Furthermore, when the limiting beam 50 is engaged with the limiting groove 40, the bottom plane of the support plate 4 abuts against the top plane of the support base 3.

[0060] Furthermore, the support assembly 20 also includes a locking member 2. When the limiting beam 50 is engaged with the limiting groove 40, the locking member 2 has a locking position that locks the limiting beam 50 into the limiting groove 40, and the locking member 2 has an unlocking position that releases the limiting beam 50 from the limiting groove 40.

[0061] When the locking component is in the locked position, it can firmly fix the limiting beam in the limiting groove, preventing the limiting beam or support plate from moving unexpectedly due to vibration during transportation or use of the battery box, thereby ensuring the stability and safety of the upper battery module.

[0062] The unlocking function of the locking mechanism makes the disassembly of the support components easy. No complicated tools or operating procedures are required. Simply adjust the locking mechanism to the unlocked position to easily remove the support plate and the limiting beam, which greatly simplifies the process of maintaining and replacing the battery module.

[0063] Furthermore, the first direction is the length direction of the box 10, and / or the second direction is the height direction of the box 10.

[0064] Specifically, the battery enclosure includes an upper module support plate and a new type of support block. The battery enclosure opens on both sides, and the sides are designed with slots to facilitate quick removal of the upper module and support plate without affecting other components. The new support block on the enclosure locks the upper module support plate on the side, preventing it from shaking or loosening, facilitating easy assembly and disassembly, and ensuring the safety, stability, and rapid maintenance of the battery module.

[0065] The upper limit beam of the support plate is locked in the slot on the support base, and the support plate is locked to the battery box by the set screw. When the support plate needs to be removed, remove the set screw and it can be easily removed through the slot on the side of the battery box.

[0066] The module fixing beam on the support plate can fix the module, and its limiting beam can cooperate with the support base to tighten it, which plays a role in stabilizing the upper module.

[0067] The bottom of the enclosure is welded with a module fixing beam, and the lower module is fixed to the module fixing beam with screws. Multiple support seats are welded on the enclosure, and the support seats are designed with slots and fixing holes. The support plate is also welded with a module fixing beam for fixing the upper module. The support plate is also designed with a limiting beam with threaded holes for fixing to the enclosure with threads. The support plate can be installed into the battery box from the top or side. Its limiting beam cooperates with the slot of the support seat, and the support plate is locked and fixed to the battery box with set screws to prevent it from shaking or loosening. The upper module is then fixed to the support plate with screws.

[0068] When maintaining the battery cell, it is only necessary to disconnect the connection with the upper electrical components and remove all the set screws. The support plate can then be removed from the side slot of the housing along with the module. This meets the mechanical strength requirements of the design and ensures the safety, stability and rapid maintenance of the battery module.

[0069] According to one aspect of the present invention, a battery is provided, including a battery housing, wherein the battery housing is the aforementioned battery housing.

A slot is provided on the side of the battery box body, allowing for quick assembly and disassembly of the upper module and support plate. Furthermore, a support base is welded to the battery box body, enabling quick engagement with the support plate and securing it using side threads. This not only improves installation efficiency but also significantly simplifies the maintenance process, enhancing both efficiency and convenience. This application addresses the support and fixation issues of battery modules during installation in a confined space double-layer battery box, proposing a new solution. It also improves the inspection and maintenance process for the upper and lower modules in a confined space double-layer battery box, enhancing efficiency and convenience.
