Description

Technical Field

[0001] This disclosure relates to the field of battery technology, and more particularly to a battery box. Background Art

[0002] A battery box is a group of batteries consisting of several individual batteries, a box body, a battery management system, and related installation structures or equipment. It has a standard battery box structure, battery box monitoring equipment, battery box connectors, and battery box environmental control equipment.

[0003] In related technologies, battery boxes mostly adopt a box-type structure, that is, the bottom is a pentahedron and the top is covered with a cover. This structure is suitable for battery boxes with low capacity or small modules. Generally speaking, it is convenient for assembly and sealing, and the design is simple. However, for battery boxes with large capacity or large modules, it is difficult to put the modules into the box, and the internal operation of the box is more inconvenient. Utility Model Content

[0004] One of the technical problems that this disclosure aims to solve is that battery boxes with a pentahedral bottom and a top cover are difficult to fit into large module batteries, and the operation inside the box is inconvenient.

[0005] To solve the above-mentioned technical problems, this disclosure provides a battery box, including a base frame mechanism for placing a battery module; and a top cover mechanism having an opening, with one side having the opening detachably connected to the base frame mechanism, and the top cover mechanism being adapted to cover the battery module.

[0006] In some embodiments, the base frame mechanism includes at least two horizontal supports and at least two vertical supports, which together form a frame.

[0007] In some embodiments, the horizontal support has a plurality of first lifting holes, and the vertical support has a plurality of second lifting holes.

[0008] In some embodiments, the base frame mechanism further includes several reinforcing beams, one end of which is connected to a longitudinal support and the other end of which is connected to another longitudinal support.

[0009] In some embodiments, the base frame mechanism further includes several sealing plates, which are disposed between two adjacent reinforcing beams or between adjacent reinforcing beams and cross supports, and the battery module is adapted to be placed on the sealing plate.

[0010] In some embodiments, the cover plate is provided with a plurality of fixing brackets, which are adapted to be inserted into the battery module.

[0011] In some embodiments, a bottom end plate is also included connected to one side of the base frame mechanism, and the battery module is adapted to abut against the bottom end plate.

[0012] In some embodiments, the top cover mechanism includes a top plate and a plurality of side plates connected to the top plate, the ends of the side plates away from the top plate being adapted to abut against the base frame mechanism.

[0013] In some embodiments, the side panel away from the top panel has a flange that is adapted to abut against the base frame mechanism.

[0014] In some embodiments, the base frame mechanism is provided with a first sealing strip, and the side of the flange facing away from the top plate is provided with a second sealing strip, the second sealing strip being adapted to abut against the first sealing strip.

[0015] Through the above technical solution, the present disclosure provides a battery box, in which a base frame mechanism is used to place battery modules for easy operation of the battery modules, and a top cover mechanism has an opening that can be placed on the base frame mechanism. The base frame mechanism and the top cover mechanism together form a battery box to cover the battery modules. Compared with a battery box with a pentahedron bottom and a top cover, this structure makes it easier to put battery modules with large capacity and large volume into the box. When the battery modules are placed on the base frame mechanism, the top, bottom and sides of the battery modules can be operated, which is more convenient. Attached Figure Description

[0031] This disclosure provides a battery box, see [link to details]. Figures 1 to 5 ,include:

[0032] The battery box comprises a base frame mechanism 1 and a top cover mechanism 2. The base frame mechanism 1 is used for positioning and holding the battery modules, while the top cover mechanism 2 is a shell with an opening on one side. The base frame mechanism 1 and the top cover mechanism 2 together form the battery box for packing the battery modules. Specifically, the battery modules are first placed on the base frame mechanism 1, and then the top cover mechanism 2 is placed on top of the battery modules. The top cover mechanism 2 and the base frame mechanism 1 fit tightly together to form the battery box. Compared with a battery box with a pentahedron at the bottom and a top cover, the battery box in this disclosure is more convenient for packing larger battery modules. At the same time, after the battery modules are placed on the base frame mechanism 1, the top and sides of the battery modules are not covered, which facilitates the operation of the battery modules.

[0033] In some embodiments, the base frame mechanism 1 consists of at least two horizontal supports 11 and at least two vertical supports 12. The horizontal supports 11 and the vertical supports 12 form a frame adapted to the size and shape of the battery module. If the number of horizontal supports 11 is greater than two, after the two horizontal supports 11 and the two vertical supports 12 form the frame, the remaining horizontal supports 11 are arranged along the length direction of the vertical supports 12. If the number of vertical supports 12 is greater than two, after the two horizontal supports 11 and the two vertical supports 12 form the frame, the remaining vertical supports 12 are arranged along the length direction of the horizontal supports 11. The horizontal supports 11 forming the frame are provided with a plurality of first lifting holes 111, and the vertical supports 12 forming the frame are provided with a plurality of second lifting holes 121. When the battery box needs to be transported, the equipment can lift the battery box through the first lifting holes 111 and the second lifting holes 121 to transport the battery module.

[0034] The base frame mechanism 1 also includes several reinforcing beams 13, which are arranged along the length of the longitudinal supports 12. One end of the reinforcing beam 13 is connected to one longitudinal support 12 that forms the frame, and the other end of the reinforcing beam 13 is connected to another longitudinal support 12 that forms the frame. On the one hand, the reinforcing beams 13 can enhance the strength of the frame formed by the transverse supports 11 and the longitudinal supports 12, reducing the possibility of deformation of the frame formed by the transverse supports 11 and the longitudinal supports 12, which could make it difficult to place the battery module. On the other hand, the several reinforcing beams 13 can improve the support capacity of the base frame mechanism 1 for the battery module, so that larger and heavier battery modules can be placed on the base frame mechanism 1.

[0035] In some embodiments, the base frame mechanism 1 further includes a sealing plate 14 laid on the frame formed by the horizontal support 11 and the vertical support 12, the sealing plate 14 being disposed between two adjacent reinforcing beams 13 or between adjacent reinforcing beams 13 and the horizontal support 11. In an optimal embodiment of this disclosure, one end of the sealing plate 14 is connected to a longitudinal support 12 surrounding the frame, and the other end of the sealing plate 14 is connected to another longitudinal support 12 surrounding the frame. One side of the sealing plate 14 is connected to a reinforcing beam 13, and the other side of the sealing plate 14 is connected to an adjacent reinforcing beam 13. Alternatively, one end of the sealing plate 14 is connected to a longitudinal support 12 surrounding the frame, and the other end of the sealing plate 14 is connected to another longitudinal support 12 surrounding the frame. One side of the sealing plate 14 is connected to a reinforcing beam 13, and the other side of the sealing plate 14 is connected to an adjacent transverse support 11. That is, several sealing plates 14 are fixed and filled in the gaps of the frame formed by the transverse support 11, the longitudinal support 12, and the reinforcing beam 13, so that the top of the base frame mechanism 1 can form an integral plane. This can not only stably support the battery module, but also reduce the possibility of dust and other foreign objects passing through the base frame mechanism 1 and contaminating the battery module.

[0036] The sealing plate 14 is provided with several fixing brackets 4. When the battery module is placed on the base frame assembly, the fixing brackets 4 are connected to the positioning groove at the bottom of the battery module. While positioning the battery module, the fixing brackets 4 can improve the stability of the battery module placed on the base frame assembly.

[0037] In some embodiments, the base frame mechanism 1 is further provided with a bottom end plate 3, which is connected to one side of the base frame mechanism 1, that is, the bottom end plate 3 is connected to a horizontal support 11. When the battery module is placed on the base frame mechanism 1, the battery module abuts against the bottom end plate 3. The bottom end plate 3 can further position the battery module and reduce the possibility of displacement of the battery module on the base frame mechanism 1. The bottom end plate 3 has several mounting holes 31, which can be used to install instruments such as power display meters to help understand the status of the battery module. A BMS mounting plate 7 is provided on the side of the bottom end plate 3 facing the sealing plate 14 for installing the BMS. The BMS is an electronic device that can monitor and manage the battery module. By collecting and calculating parameters such as voltage, current, temperature and SOC, it controls the charging and discharging process of the battery module to protect the battery module and improve its overall performance.

[0038] In some embodiments, the base frame mechanism 1 and the bottom end plate 3 are both made of lightweight metal materials. In a preferred embodiment of this disclosure, the horizontal support 11, the vertical support 12, the reinforcing beam 13, the sealing plate 14 and the bottom end plate 3 are all made of aluminum alloy materials, which can reduce the overall weight of the battery box and facilitate hoisting and transportation.

[0039] In some embodiments, the top cover mechanism 2 consists of a top plate 21 and a plurality of side plates 22. Specifically, the plurality of side plates 22 are fixed around the side of the top plate 21. The top cover mechanism 2 is matched with the size of the battery module. When the top cover mechanism 2 is mounted on the base frame mechanism 1, the end of the side plate 22 away from the top plate 21 abuts against the base frame mechanism 1. The top plate 21 is in contact with the top of the battery module, and the side plate 22 is in contact with the side of the battery module. This helps to reduce the possibility of the battery module being damaged due to a collision between the battery module and the top cover mechanism 2, which may affect the service life of the battery module.

[0040] In some embodiments, a flange 23 is provided at the end of the side plate 22 away from the top plate 21. The flange 23 is provided along the length direction of the side plate 22 and extends toward the side plate 22 in the direction away from the top plate 21. When the top cover mechanism 2 is placed on the base frame mechanism 1, the flange 23 is in contact with the horizontal support 11 or the vertical support 12. This can improve the sealing performance of the battery box, reduce the possibility of dust and other foreign objects contaminating the battery module, and thus ensure the service life of the battery module.

[0041] In some embodiments, to improve the sealing performance of the battery box, a first sealing strip 5 is provided on the base frame mechanism 1, and a second sealing strip 6 is provided on the top cover mechanism 2. Specifically, the first sealing strip 5 is arranged on the horizontal support 11 and the vertical support 12, that is, the first sealing strip 5 is provided on the frame formed by the horizontal support 11 and the vertical support 12. The second sealing strip 6 is provided on the side of the flange 23 facing away from the side plate 22. After the battery module is placed on the base frame mechanism 1 and the top cover mechanism 2 is placed on the battery module, the second sealing strip 6 abuts against the first sealing strip 5, and the first sealing strip 5 and the second sealing strip 6 form a sealing ring around the battery module, which can further reduce the contamination of the battery module by dust and other foreign objects. Both the first sealing strip 5 and the second sealing strip 6 adopt double-sided adhesive, which can seal the battery box and bond the top cover mechanism 2 and the base frame mechanism 1 at the same time, which facilitates the subsequent fixing of the top cover mechanism 2 to the base frame mechanism 1 to form the battery box.

[0042] In some embodiments, the top cover mechanism 2 is made of lightweight metal material. In a preferred embodiment of this disclosure, the top plate 21 and the side plate 22 are both made of aluminum alloy material, which can reduce the overall weight of the battery box, so as to facilitate the top cover mechanism 2 to be placed on the base frame mechanism 1 to complete the packing of the battery module.

[0043] This disclosure provides a battery box, including a base frame mechanism 1 for placing battery modules. The base frame mechanism 1 consists of a horizontal support 11 and a vertical support 12 forming a frame. The horizontal support 11 and the vertical support 12 are provided with first sealing strips 5. The horizontal support 11 has a plurality of first lifting holes 111, and the vertical support 12 has a plurality of second lifting holes 121. A plurality of reinforcing beams 13 are also provided along the length of the vertical support 12. Sealing plates 14 are arranged between two adjacent reinforcing beams 13 and between adjacent reinforcing beams 13 and the horizontal support 11. A plurality of fixing brackets 4 are provided on the sealing plates 14. The horizontal support 11 is also provided with a bottom plate 3, and the bottom plate 3 has a plurality of mounting holes 31. The top cover mechanism 2 includes a top plate 21 and a plurality of side plates 22. The plurality of side plates 22 are arranged around the side of the top plate 21. The side of the side plate 22 away from the top plate 21 is provided with a flange 23, and the side of the flange 23 facing away from the top plate 21 is provided with a second sealing strip 6.

[0044] In summary, the battery box disclosed herein has the following advantages: When assembling the battery module, the battery module is first placed on the base frame mechanism 1. The frame formed by the horizontal support 11 and the vertical support 12 matches the size of the battery module. The reinforcing beam 13 supports and strengthens the frame formed by the horizontal support 11 and the vertical support 12. The fixing bracket 4 is embedded in the groove at the bottom of the battery module for positioning. The bottom end plate 3 abuts against the side of the battery module for further positioning. Several sealing plates 14 fill the space between adjacent horizontal supports 11 and reinforcing beams 13, and between two adjacent reinforcing beams 13 to form a plane, which allows the battery module to be placed stably on the base frame mechanism 1. Furthermore, the positioning of the battery module on the base frame mechanism 1 by the fixing bracket 4 and the bottom end plate 3 reduces the possibility of displacement of the battery module on the base frame mechanism 1, which could lead to difficulties in assembly. The top cover mechanism 2 is then placed on the battery module, and the flange 23 presses the second sealing strip 6 against the first sealing strip 5. The top cover mechanism 2 and the base frame mechanism 1 form a sealed box to seal the battery module. This structure not only facilitates the loading of large-volume battery modules but also facilitates the operation of the battery modules. Finally, the top cover mechanism 2 and the base frame mechanism 1 are fixed together to form a stable battery box for packaging the battery module. The battery box can be lifted onto transport equipment for transportation or onto the equipment to be installed through the first lifting hole 111 and the second lifting hole 121, which is very convenient.
