Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a battery pack hoisting fixture. Background Technology

[0002] A battery pack is a complete, independently usable energy storage unit that combines multiple individual battery cells in series, parallel, or mixed connection and integrates a sophisticated management and control system. After the battery pack is loaded, it needs to be installed into the device in which it is used. During the loading process, the battery pack needs to be suspended and lowered from top to bottom into the battery compartment of the device in which it is used, so that the battery pack can be installed into the device for power supply.

[0003] Although the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: During the installation process of existing battery packs, the hanging lugs of the suspension device need to be inserted into the chassis opening of the battery pack to suspend the battery pack. However, when the battery pack is moved laterally by the suspension device, especially when the suspension device moves the battery pack laterally at a relatively fast speed, the chassis of the battery pack and the hanging lugs of the suspension device are prone to lateral sliding due to inertia, which can easily cause the hanging lugs to detach from the chassis of the battery pack and affect the stability of the suspended battery pack. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a battery pack hoisting fixture that prevents lateral sliding and provides stable fixation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery pack hoisting fixture, including a suspension cable, the bottom of which is detachably provided with an anti-slip connecting device, and the bottom end of the suspension cable is detachably provided with a base plate for supporting the battery pack and fixedly connected to the battery pack through the anti-slip connecting device. The side wall of the base plate is provided with a side slot into which the anti-slip connecting device can be inserted, and the base plate is also provided with a fixing bolt that can engage with the anti-slip connecting device.

[0006] A further improvement is that an upper suspension frame is fixedly connected to the top of the suspension cable.

[0007] A further improvement is that the anti-slip connection device includes a connecting ring detachably connected to the bottom end of the suspension cable and a snap-fit ​​block detachably connected to the bottom of the connecting ring via a pin. The snap-fit ​​block can be snapped into the chassis through a side slot and its end can engage with a fixing bolt.

[0008] A further improvement is that the snap-in block includes a vertical plate that is detachably connected to the bottom of the connecting ring via a pin and a positioning groove integrally formed on one side of the vertical plate. A transverse hook is integrally formed at the bottom end of the vertical plate, and an engagement groove for engaging and fixing bolts is integrally formed on one side of the end of the transverse hook.

[0009] A further improvement is that an insertion groove is integrally formed on the upper surface of the side of the horizontal hook claw closest to the vertical plate.

[0010] A further improvement is that a top bead structure is provided on the upper surface of the transverse claw near the insertion groove.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, the battery pack is placed on the chassis, so that the chassis supports the battery pack. The locking block is installed into the bottom end of the suspension cable, and the lateral hook of the locking block is extended into the side slot on one side of the chassis. The lateral hook is moved so that its engagement groove engages with the fixing bolt, thereby providing resistance to lateral sliding. Then, the suspension cable is pulled up, so that the edge of the side slot engages in the locking groove. Thus, when lateral movement occurs, the locking groove further abuts against the edge of the side slot of the chassis to prevent the lateral hook from laterally moving out, thereby greatly improving the stability during suspension and avoiding the chassis from detaching from the suspension cable due to lateral inertia during suspension.

[0014] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0015] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a battery pack hoisting fixture, including a suspension cable 3, with an anti-slip connecting device 5 detachably provided at the bottom of the suspension cable 3, and a base 4 for supporting the battery pack 100 and fixedly connected to the battery pack 100 detachably provided at the bottom end of the suspension cable 3 through the anti-slip connecting device 5. The side wall of the base 4 is provided with a side slot 41 into which the anti-slip connecting device 5 can be inserted. A fixing bolt 42 that can engage with the anti-slip connecting device 5 is also penetrated and engaged on the base 4. The anti-slip connecting device 5 includes a connecting ring 51 detachably connected to the bottom end of the suspension cable 3 and a pin detachably connected to the connecting ring. The bottom of the connecting ring 51 has a locking block 52. The locking block 52 can be inserted into the chassis 4 through the side slot 41 and its end can engage with the fixing bolt 42. The locking block 52 includes a vertical plate 521 that is detachably connected to the bottom of the connecting ring 51 by a pin and a positioning groove 522 integrally formed on one side of the vertical plate 521. The bottom end of the vertical plate 521 has an integrally formed horizontal hook 523. The end of the horizontal hook 523 has an integrally formed engagement groove 525 on one side to engage with the fixing bolt 42. In use, the battery pack 100 is placed on the chassis 4 so that the chassis 4 supports the battery pack 100. Then the horizontal hook 52 of the anti-slip connecting device 5 is engaged with the bolt 42. Insert the hook 523 into the side slot 41 on the side wall of the chassis 4, and twist the vertical plate 521 of the locking block 52 to cause the horizontal hook 523 to twist synchronously. Finally, the engagement groove 525 of the horizontal hook 523 engages with the outer wall of the fixing bolt 42. Then, place the connecting ring 51 on the top of the locking block 52 and connect the two with a pin. Then, install the connecting ring 51 onto the suspension cable 3. In normal use, four suspension cables 3 and four anti-slip connecting devices 5 need to be set up, symmetrically distributed in two groups on both sides of the chassis 4 to ensure that the chassis 4 is evenly stressed and does not tilt. Then, pull up the suspension cables 3. This allows the chassis 4 and battery pack 100 to be suspended and lifted. When lateral movement occurs, the end of the lateral hook 523 is engaged with the fixing bolt 42 through the engagement groove 525 to resist the lateral force. This prevents the lateral hook 523 from detaching during lateral movement, ensuring a stable connection with the chassis 4. This significantly improves the stability during suspension and prevents the chassis 4 from detaching from the suspension cable 3 due to lateral inertia. Once the battery pack 100 is suspended to the appropriate position, the locking block 52 can be twisted to disengage from the side slot 41, allowing the battery pack 100 and chassis 4 to be installed together into the battery-using equipment. Meanwhile, during use, a force parallel to the horizontal hook 523 can be applied to the vertical plate 521, thereby further improving the engagement strength between the engagement groove 525 and the fixing bolt 42, further improving the stability during use. After the snap-in block 52 and the suspension cable 3 are installed, they will not be disassembled unless replacement or maintenance is required, to prevent frequent disassembly from affecting the stability of use. The top of the suspension cable 3 is fixedly connected to the upper suspension frame 1. When suspending and lifting, the suspension cable 3, chassis 4 and battery pack 100 can be lifted directly by raising the upper suspension frame 1. This helps to make the upward pulling force more even through the upper suspension frame 1 and further avoids the chassis 4 from tilting when pulling up. On the upper surface of the side of the horizontal hook 523 near the vertical plate 521, there is also an integrally formed locking groove 524, which is beneficial to allow the chassis 4 at the edge of the side slot 41 to be locked into the locking groove 524 during the lifting process. Then, when lateral movement occurs, the locking groove 524 abuts against the edge of the side slot 41 of the chassis 4 to prevent the horizontal hook 523 from lateral movement and falling out, thereby further improving the stability during suspension. A top bead structure 526 is also provided on the upper surface of the transverse hook 523 near the insertion groove 524. The top bead structure is the same as the top bead structure on the umbrella. The top bead structure 526 is used to further increase the resistance when the transverse hook 523 is inserted and removed. When the transverse hook 523 is removed, it moves along the side slot 41 and moves the top bead structure 526 to the position of the side slot 41. This can generate additional removal resistance for the top bead structure 526, thereby further improving the firmness and stability of the transverse hook 523 after it is inserted into the chassis 4.

[0016] The working principle of this utility model is as follows: When using this utility model, the battery pack 100 is placed on the chassis 4, allowing the chassis 4 to support the battery pack 100. Then, the horizontal hook 523 of the locking block 52 of the anti-slip connecting device 5 is inserted into the side slot 41 opened on the side wall of the chassis 4. The vertical plate 521 of the locking block 52 is twisted, causing it to drive the horizontal hook 523 to twist synchronously. Finally, the engagement groove 525 of the horizontal hook 523 engages with the outer wall of the fixing bolt 42. Then, the connecting ring 51 is placed on top of the locking block 52, and the two are connected by a pin. Finally, the connecting ring 51 is installed onto the suspension cable 3. During normal use, four suspension cables 3 and four anti-slip connecting devices 5 are required, symmetrically distributed in two groups on both sides of the chassis 4 to ensure that the chassis 4 is evenly stressed and does not tilt. Then, pulling up the suspension cables 3 will suspend and lift the chassis 4 and the battery pack 100. When lateral movement occurs, the end of the lateral hook 523 is engaged with the fixing bolt 42 through the engagement groove 525 to resist the lateral force. Thus, the lateral hook 523 will not laterally move out during lateral movement, making it stably connected to the chassis 4. This greatly improves the stability during suspension and prevents the chassis 4 from detaching from the suspension cables 3 due to lateral inertia during suspension.
