Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology and relates to a modular battery pack. Background Technology

[0002] The voltage and capacity of individual battery cells are relatively small and cannot meet the battery application requirements of energy storage systems. Therefore, multiple battery cells need to be connected in series and parallel to form a high-voltage battery string. In order to facilitate transportation, save space, and provide effective protection for the batteries, more and more battery packs are being installed in PACK (packaging, encapsulation, and assembly) boxes and connected in series and parallel to form a battery string.

[0003] In actual use, battery packs are used as backup power sources for temporary use during power failures. The required capacity of battery packs varies depending on the purpose. Existing battery packs are generally of fixed capacity, which cannot be adjusted by the operator according to actual needs, making them inconvenient to use.

[0004] Based on this, we designed a modular battery pack. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a modular battery pack. The technical problem this device aims to solve is: how to achieve battery pack assembly and adjustment for ease of use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A modular battery pack includes a main control panel and several battery boxes. Several batteries are installed inside each battery box, and each battery box is covered. The front end of the main control panel has a charging interface and a discharging interface. A connecting mechanism is provided between the main control panel and the battery boxes. Two conductive plates are provided on both sides of each battery box for connecting the positive and negative terminals of the batteries, and electrical contact blocks are provided on both sides of each conductive plate. An electrical contact piece is provided on the back of the main control panel. The electrical contact piece abuts against the electrical contact block at the corresponding position, and the electrical contact blocks on adjacent battery boxes abut against each other.

[0008] An arc-shaped copper sheet is fixed on the electrical contact block.

[0009] With the above structure, the arc-shaped copper sheet will increase the clamping force between the electrical contact blocks during use, improve the connection stability, and prevent poor contact.

[0010] The connection mechanism includes a fixed connecting column fixed to the back of the main control panel, and a limit hole is provided on the fixed connecting column. Cover plates are fixed at both ends of the battery box. The cover plates are provided with sliding grooves, and two push blocks are slidably arranged in the sliding grooves. Two sliding holes are provided on both sides of the battery box, and a sliding connecting column is slidably arranged in one of the sliding holes. The sliding connecting column is also provided with a limit hole. A connecting rod is connected to the sliding connecting column. The connecting rod is fixedly connected to one of the push blocks. Two fixing plates are fixed inside the battery box. A limit rod is slidably arranged on the fixing plate, and a triangular block is fixed on the limit rod. A conical block is fixed on the other push block, and the conical block abuts against the inclined surface of the triangular block.

[0011] Using the above structure, during use, the fixed connecting post is inserted into the sliding hole on one side of the battery box. Then, one of the push blocks on the battery box is pushed, causing the conical block to press against the two triangular blocks, which in turn causes the two limiting rods to insert into the limiting holes of the fixed connecting post, thus assembling the main control panel and the battery box. To assemble two battery boxes, first align the two battery boxes, then push one of the push blocks of one battery box, causing the sliding connecting post to extend outward and insert into the corresponding sliding hole of the other battery box. Then, repeat the above steps, pushing one of the push blocks of the other battery box, causing the conical block to press against the two triangular blocks, which in turn causes the two limiting rods to insert into the limiting holes of the sliding connecting post, thus assembling the battery boxes. Operators can assemble them as needed. The more battery boxes assembled, the larger the capacity of the battery pack.

[0012] The triangular block has a magnetic sheet embedded on its side near the conical block, and the conical block is made of iron.

[0013] With the above structure, when the conical block is reset during use, the two triangular blocks will approach the conical block under the action of magnetic force, thereby achieving a shrinking effect. This allows the device to automatically disengage from the limiting hole and prevent it from jamming when the battery box is removed.

[0014] The sliding connecting column has a groove on its side end, and a baffle is hinged to the inside of the groove by a torsion spring, and the baffle covers the outside of the corresponding electrical contact block.

[0015] With the above structure, during use, the empty electrical contact connection blocks on the last battery box to be assembled will be blocked by the baffle, which can prevent electric shock or leakage. Moreover, when the sliding connection post extends outward and is inserted into the corresponding sliding hole, the baffle will compress the torsion spring under the obstruction of the sliding hole and completely sink into the groove, which will not affect the use of the electrical contact connection block. When the sliding connection post retracts, the baffle will pop outward under the action of the torsion spring and cover the outside of the electrical contact connection block again.

[0016] Compared with existing technologies, this modular battery pack has the following advantages:

[0017] 1. Through the main control panel, battery box, connecting mechanism, electrical contact connecting block and electrical contact connecting piece, the battery boxes can be spliced ​​together and powered on. Operators can select the appropriate number of battery boxes to splice together as needed to change the capacity of the battery PACK box, making it more convenient to use.

[0018] 2. By using arc-shaped copper sheets, the clamping force between the electrical contact blocks is increased, the connection stability between battery boxes is improved, and poor contact is prevented.

[0019] 3. The connection mechanism enables the splicing of the main control panel and the battery box. The splicing method is simple, the connection structure is stable, and it is more convenient to use.

[0020] 4. The baffle can block the empty electrical contact connection blocks on the battery box that is to be spliced ​​last, which can prevent electric shock or leakage. Moreover, when the sliding connection post is inserted into the corresponding sliding hole, the baffle will be completely embedded in the groove, which will not affect the use of the electrical contact connection block.

[0031] Please see Figure 1-5 This embodiment provides a modular battery pack, including a main control panel 1 and several battery boxes 2. Several batteries 5 are installed inside the battery boxes 2, and a cover 3 is provided on the battery boxes 2. The front end of the main control panel 1 is provided with a charging interface 6 and a discharging interface 7. A connecting mechanism 4 is provided between the main control panel 1 and the battery boxes 2. Two conductive plates 9 are provided on both sides of the battery boxes 2 for connecting the positive and negative terminals of the batteries 5, and electrical contact blocks 10 are provided on both sides of the conductive plates 9. An electrical contact piece 8 is provided on the back of the main control panel 1. The electrical contact piece 8 abuts against the electrical contact block 10 at the corresponding position. The electrical contact blocks 10 on adjacent battery boxes 2 abut against each other.

[0032] An arc-shaped copper sheet 11 is fixed on the electrical contact block 10; during use, the arc-shaped copper sheet 11 will increase the clamping force between the electrical contact blocks 10, improve the connection stability, and prevent poor contact.

[0033] The connecting mechanism 4 includes a fixed connecting post 401 fixed to the back of the main control panel 1, and a limit hole 402 is provided on the fixed connecting post 401. Cover plates 403 are fixed at both ends of the battery box 2. The cover plates 403 are provided with sliding grooves 404, and two push blocks 405 are slidably arranged in the sliding grooves 404. Two sliding holes 406 are provided on both sides of the battery box 2, and a sliding connecting post 407 is slidably arranged in one of the sliding holes 406. The sliding connecting post 407 is also provided with a limit hole 402. A limiting hole 402 is provided. A connecting rod 409 is connected to a sliding connecting post 407. The connecting rod 409 is fixedly connected to one of the push blocks 405. Two fixing plates 410 are fixed inside the battery box 2. A limiting rod 411 is slidably provided on the fixing plate 410, and a triangular block 412 is fixed on the limiting rod 411. A conical block 413 is fixed on the other push block 405, and the conical block 413 abuts against the inclined surface of the triangular block 412. In use, the fixing connecting post 401 is inserted. In the sliding hole 406 on one side of the battery box 2, push one of the push blocks 405 on the battery box 2, so that the conical block 413 squeezes the two triangular blocks 412, and drives the two limiting rods 411 to insert into the limiting hole 402 of the fixed connecting column 401. This realizes the assembly of the main control panel 1 and the battery box 2. The assembly between the two battery boxes 2 can be done by first aligning the two battery boxes 2, and then pushing one of the push blocks 405 of one battery box 2, so that the sliding connecting column 407 extends outward and inserts into the corresponding sliding hole 406 of the other battery box 2. Then, in the same way, push one of the push blocks 405 of the other battery box 2, so that the conical block 413 squeezes the two triangular blocks 412, and drives the two limiting rods 411 to insert into the limiting hole 402 of the sliding connecting column 407. This realizes the assembly between the battery boxes 2. The operator can assemble them as needed. The more battery boxes 2 are assembled, the larger the capacity of the battery PACK box.

[0034] A magnetic sheet is embedded on the side of the triangular block 412 near the conical block 413, and the conical block 413 is made of iron. When in use, when the conical block 413 is reset, the two triangular blocks 412 will approach the conical block 413 under the action of magnetic force, thereby achieving a shrinking effect and automatically disengaging from the limiting hole 402 to prevent the device from getting stuck when disassembling the battery box 2.

[0035] The sliding connecting post 407 has a groove 414 on its side end. A baffle 408 is hinged to the inside of the groove 414 by a torsion spring, and the baffle 408 covers the outside of the corresponding electrical contact block 10. In use, the empty electrical contact block 10 on the last battery box 2 to be assembled will be blocked by the baffle 408, which can prevent electric shock or leakage. When the sliding connecting post 407 extends outward and is inserted into the corresponding sliding hole 406, the baffle 408 will compress the torsion spring under the obstruction of the sliding hole 406 and completely sink into the groove 414, which will not affect the use of the electrical contact block 10. When the sliding connecting post 407 retracts, the baffle 408 will pop outward under the action of the torsion spring and cover the outside of the electrical contact block 10 again.

[0036] In this embodiment, the above-mentioned fixing methods are the most commonly used fixing connection methods in the field, such as welding and bolt connection; the above-mentioned electrical components, such as the storage battery 5, are all existing technology products that can be directly purchased and used on the market, and the specific principles will not be elaborated.

[0037] The working principle of this utility model:

[0038] In use, the fixed connecting post 401 is inserted into the sliding hole 406 on one side of the battery box 2. Then, one of the push blocks 405 on the battery box 2 is pushed, causing the conical block 413 to press against the two triangular blocks 412, which in turn causes the two limiting rods 411 to insert into the limiting hole 402 of the fixed connecting post 401. This completes the assembly of the main control panel 1 and the battery box 2. The assembly between the two battery boxes 2 can be done by first aligning the two battery boxes 2, and then pushing one of the push blocks 405 of one battery box 2, causing the sliding connecting post 407 to extend outward and insert into the corresponding sliding hole 406 of the other battery box 2. At this time, the baffle 408 will... The compression spring is blocked by the sliding hole 406 and completely embedded in the groove 414, which will not affect the use of the electric contact block 10. Then, following the same steps, one of the push blocks 405 of the other battery box 2 is pushed, so that the cone block 413 presses the two triangular blocks 412, which drives the two limit rods 411 to insert into the limit hole 402 of the sliding connecting column 407, thus realizing the assembly between the battery boxes 2. The operator can assemble them as needed. The more battery boxes 2 are assembled, the larger the capacity of the battery PACK box. Moreover, the empty electric contact block 10 on the last battery box 2 to be assembled will be blocked by the baffle 408, which can prevent electric shock or leakage.
