Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery protection technology, and in particular to a positioning protection component for a battery management system. Background Technology
[0002] A battery management system (BMS) is a device used to monitor and manage battery packs, playing a crucial role, especially in electric vehicles and energy storage systems. It is responsible for battery charge and discharge management, temperature control, and voltage monitoring, ensuring the battery operates under safe and efficient conditions. Positioning protection components are a key design element of the BMS, used to ensure the battery pack is not damaged by external factors during use.
[0003] In traditional technologies, positioning and protection components are mostly connected to or fitted onto the outside of the battery pack through a fixed structure to provide physical protection and positioning for the batteries. This design typically uses a robust frame structure or plastic casing to firmly fix the individual battery cells in a certain position, ensuring the stability and safety of the battery pack.
[0004] However, since most protective components are secured with screws, fasteners, and other fasteners, and are tightly integrated with the battery pack, the disassembly process can be time-consuming. Especially when the battery pack is installed compactly, disassembling and replacing the battery becomes extremely complex, sometimes requiring the entire protective casing to be removed to access the battery. This not only increases the difficulty of maintenance but may also lead to unnecessary damage to the battery pack during disassembly, affecting the overall stability and lifespan of the system. Summary of the Invention
[0005] To overcome the above shortcomings, this utility model provides a positioning protection component for a battery management system, which aims to improve the problem that traditional protection components are mostly fixed by screws, fasteners and other means, which makes disassembly inconvenient and increases maintenance difficulty.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning and protection component for a battery management system, comprising a base, a battery pack fixedly connected to the top of the base, a protective mechanism provided on the top of the base for protecting the battery pack, an installer fixedly connected to the outside of the battery pack, a connector slidably connected inside the installer, a wire fixedly connected to the side of the connector away from the installer, a slot provided on the outside of the connector, and a stabilizing mechanism designed inside the installer for increasing the connection stability of the wire;
[0007] The protective mechanism includes a protective cover, the bottom of which is slidably connected to the inside of the base. Two mounting shells are fixedly connected to the outside of the base. A return spring is fixedly connected inside each of the two mounting shells. A limit block is fixedly connected to the opposite side of each of the two return springs. A pin is fixedly connected inside each of the two limit blocks. The opposite side of each pin passes through the base and engages with the outside of the protective cover.
[0008] As a further description of the above technical solution:
[0009] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.
[0010] As a further description of the above technical solution:
[0011] The limiting block is slidably connected inside the mounting housing, and the pin passes through both ends of the mounting housing.
[0012] As a further description of the above technical solution:
[0013] A handle is fixedly connected to the side of the pin away from the limiting block.
[0014] As a further description of the above technical solution:
[0015] The stabilizing mechanism includes a slide rod slidably connected inside the mounter. A slider is fixedly connected to the bottom of the slide rod, and a compression spring is fixedly connected to the bottom of the slider. Connecting rods are rotatably connected to both sides of the slider. U-shaped frames are rotatably connected to the bottom of both connecting rods. Locking rods are fixedly connected to the bottom of both U-shaped frames. Clamps are fixedly connected to the opposite sides of both locking rods, and both clamps engage with the locking grooves.
[0016] As a further description of the above technical solution:
[0017] The slider is slidably connected inside the mounter, and both connecting rods are slidably connected inside the mounter.
[0018] As a further description of the above technical solution:
[0019] The bottom of the compression spring is fixedly connected inside the mounter.
[0020] As a further description of the above technical solution:
[0021] A push handle is fixedly connected to the top of the slide rod.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the battery pack is connected to the base and can be used by connecting the wires through the installer. During use, the protective cover is connected to the outside of the battery pack. When the battery pack needs to be replaced or repaired, the handle is pulled outward to push the pin rod to cause the limit block to compress the reset spring and retract into the inside of the mounting shell. The barrier plate automatically falls due to gravity and blocks the limit block, preventing it from moving. At this time, the protective cover can be removed to carry out the battery pack replacement and repair work. This achieves the effect of conveniently removing the protective cover through the internal structure of the mounting shell, which facilitates the maintenance and repair of the battery pack and improves the service life of the battery.
[0024] In this invention, when installing the wire, the push handle is used to push the slide bar downwards, causing the slider to move downwards and compress the compression spring. As the slider moves, the connecting rods on both sides drive the U-shaped frame, causing the two locking rods to separate the two clamps. After the wire and connector are slid into the installer, the push handle is released. The rebound force of the compression spring pushes the slider upwards, causing the two locking rods to engage with the two clamps and fix them in place. This achieves the effect of further enhancing the stability of the wire connection through the stabilizing mechanism, enabling the device to be used in complex environments and improving its practicality.

[0033] The protective mechanism includes a protective cover 3, which protects the battery pack 2. The bottom of the protective cover 3 is slidably connected to the inside of the base 1. Two mounting shells 4 are fixedly connected to the outside of the base 1. The mounting shells 4 are used to fix the internal structure. A return spring 5 is fixedly connected inside each of the two mounting shells 4. The return spring 5 provides elastic force to push the limit block 6. Limit blocks 6 are fixedly connected to the opposite sides of the two return springs 5. Limit blocks 6 are used to prevent the return springs 5 from falling off. Pins 7 are fixedly connected inside each of the two limit blocks 6. Pins 7 are used to engage and fix the device. The opposite sides of the two pins 7 pass through the base 1 and engage with the outside of the protective cover 3. The top of the mounting shell 4 is fixedly connected to a fixing box 8, which serves to fix the internal structure. Inside the fixing box 8, a sliding plate 9 is slidably connected, which serves to connect to the baffle plate 10. The bottom of the sliding plate 9 is fixedly connected to the baffle plate 10, which serves to prevent the limit block 6 from moving. The bottom of the baffle plate 10 abuts against the top of the limit block 6. The limit block 6 is slidably connected inside the mounting shell 4. A pin 7 passes through both ends of the mounting shell 4. A handle 11 is fixedly connected to the side of the pin 7 away from the limit block 6.
[0034] Reference Figure 1 and Figures 3-4The stabilizing mechanism includes a slide rod 16, which connects to a slider 17. The slide rod 16 is slidably connected inside the mounter 12. The bottom of the slide rod 16 is fixedly connected to the slider 17, which connects to a compression spring 18. The compression spring 18 provides elastic force to push the slider 17. Both sides of the slider 17 are rotatably connected to connecting rods 19, which connect to U-shaped frames 20. The bottom of both connecting rods 19 is rotatably connected to U-shaped frames 20, which connect to locking rods 21. The bottom of both U-shaped frames 20 is fixedly connected to locking rods 21, which connect to clamps 22.

[0035] Working principle: Connect the battery pack 2 to the base 1 and connect the wire 14 through the installer 12 for use. During use, connect the protective cover 3 to the outside of the battery pack 2. When the battery pack 2 needs to be replaced or repaired, pull the pin 7 outward by the handle 11 to cause the limit block 6 to compress the reset spring 5 and retract it into the mounting shell 4. The barrier plate 10 will automatically fall down due to gravity and block the limit block 6 so that it cannot move. At this time, the protective cover 3 can be removed to replace or repair the battery pack 2.
[0036] When installing wire 14, push the slide bar 16 downward by pushing the handle 23 to move the slider 17 downward and compress the compression spring 18. When the slider 17 moves, it drives the U-shaped frame 20 through the connecting rods 19 on both sides, so that the two locking rods 21 drive the two clamps 22 to separate relative to each other. After sliding the wire 14 and connector 13 into the installer 12, release the push handle 23. The rebound force of the compression spring 18 pushes the slider 17 upward, so that the two locking rods 21 drive the two clamps 22 to engage and fix with the slot 15.
