[0035] The battery pack 200 is an integrated unit assembled from multiple battery modules for storing and providing electrical energy. It is a higher-level component in the battery system, usually consisting of several battery modules, connectors, a battery management system (BMS), a cooling system, an electrical interface, and a housing.

[0036] The main function of the battery pack 200 is to integrate multiple battery modules together to form an integral unit. Battery modules are connected in parallel or in series to increase the voltage, capacity or power of the battery system. The battery pack 200 is also responsible for providing other functions and features required by the battery system, such as electrical interfaces for connecting to external systems, heat dissipation systems for controlling temperature, and housings for protecting batteries and other auxiliary devices and components. Similar to battery modules, the battery pack 200 is also equipped with a battery management system (BMS) for monitoring and managing the entire battery system. The BMS monitors the status of the battery module, controls the charging and discharging process, and implements battery protection and balance control to ensure the safety and stable performance of the battery. The battery pack 200 is usually also equipped with a heat dissipation system for controlling the battery temperature. The heat dissipation system can effectively cool the battery module to prevent overheating and maintain the battery within a suitable operating temperature range. The battery pack 200 also includes a housing or protective structure for protecting the battery module and BMS, and providing physical support and isolation while ensuring the safety and reliability of the battery system.

[0037] The battery pack 200 is widely used in electric vehicles, hybrid vehicles, energy storage systems and other applications that require large capacity and high voltage. It is a key component of the electric energy system, providing a higher level of electrical energy storage and management to meet the needs of different applications.

[0038] As mentioned in the background technology, the existing battery pack 200 usually needs to be hoisted and transferred during the manufacturing process. The existing hoisting and transfer is mainly performed through the hook part 300. However, because the battery pack 200 itself has a certain weight, it is easy to shake relative to the hook part 300 during the hoisting and transfer process, which poses a certain safety hazard.

[0039] Please refer to Figure 1-Figure 5 The hoisting sling 100 and the battery pack hoisting system 1000 provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0040] refer to Figure 1 and Figure 2 The lifting sling 100 is applied to the battery pack lifting system 1000, and the lifting tool includes a lifting component 110, a supporting component 120 and an anti-slip component 130; wherein the lifting component 110 is rotatably connected to the supporting component 120, and a lifting hole 111 is opened on the lifting component 110, and the lifting hole 111 is used to accommodate the hook component 300, and the supporting component 120 is used to support the battery pack 200, and one end of the anti-slip component 130 is connected to the supporting component 120, and the other end of the anti-slip component 130 is used to be connected to the hook component 300.

[0041] During use, the lifting sling 100 can support the battery pack 200 through the support member 120, so that the lifting hole 111 can accommodate the hook member 300, and the support member 120 and the hook member 300 are connected through the anti-slip member 130, thereby improving the stability during lifting and transportation, thereby reducing lifting shaking and reducing safety hazards.

[0042] refer to Figure 2-Figure 4 The supporting member 120 includes a connected support rod 121 and a support platform 122. The support rod 121 is rotatably connected to the hanging member 110, and the support platform 122 is connected to one end of the anti-slip member 130. The support platform 122 is used to support the battery pack 200, and the end surface area of ​​the support platform 122 is larger than the end surface area of ​​the support rod 121.

[0043] It is worth noting that the battery pack 200 is usually provided with through holes around the periphery for accommodating the support rod 121 and the hanging member 110, and the end surface of the support platform 122 close to the support rod 121 is used to support the battery pack 200 to ensure that the battery pack 200 can be supported for lifting and movement.

[0044] refer to Figure 2 The lifting sling 100 further includes a limit spring 160, which is sleeved on both the lifting member 110 and the supporting member 120. Specifically, a portion of the limit spring 160 is sleeved on the lower portion of the lifting member 110, and another portion is sleeved on the supporting rod 121. The limit spring 160 can play a certain role in limiting the relative rotation of the two, and provide an elastic force for the rotation reset.

[0045] In this embodiment, in order to improve the matching stability between the support rod 121 and the hanging member 110 and prevent the two from being easily separated, a groove 1211 can be opened at one end of the support rod 121, and one end of the hanging member 110 can be accommodated in the groove 1211 and rotatably connected to the groove 1211.

[0046] Furthermore, the opening of the groove 1211 is consistent with the relative rotation direction between the hanging member 110 and the support rod 121, and can also play a guiding and limiting role in the relative rotation between the two.

[0047] Specifically, the hanging member 110 is provided with a first transfer hole 112, and the side wall of the groove 1211 is penetrated with a second transfer hole 1212, and the first transfer hole 112 and the second transfer hole 1212 are rotatably connected through the latch 140. It is worth noting that the opening directions of the first transfer hole 112 and the second transfer hole 1212 are consistent, thereby ensuring that the latch 140 can be connected and matched with both at the same time. In addition, in order to ensure rotation flexibility, a lubricating medium may be applied to the positions where both ends of the latch 140 contact the first transfer hole 112 and the second transfer hole 1212, specifically including but not limited to: lubricating oil, grease; or bearings are arranged on both sides of the latch 140, and the bearings play a role of rotational support for the latch 140 and the first transfer hole 112 and the second transfer hole 1212.

[0048] In this embodiment, the extension direction of the first adapter hole 112 is consistent with the extension direction of the suspension hole 111, which can avoid the negative impact on the cooperation between the suspension hole 111 and the hook member 300 when the suspension member 110 and the support rod 121 rotate relative to each other.

[0049] refer to Figure 2 and Figure 4 The support platform 122 is provided with an anti-drop hole 1221, and one end of the anti-drop member 130 is accommodated in the anti-drop hole 1221. In addition, the support platform 122 is provided with a first positioning hole 1222 and a second positioning hole 1223, the first positioning hole 1222 and the second positioning hole 1223 are spaced apart and both communicate with the anti-drop hole 1221, the first positioning hole 1222 and the second positioning hole 1223 are connected by a top screw 150, a part of the top screw 150 is accommodated in the anti-drop hole 1221, and one end of the anti-drop member 130 is connected to the top screw 150.

[0050] In the above technical solution, by setting the anti-slip hole 1221, the first positioning hole 1222 and the second positioning hole 1223, it is convenient to connect the end of the anti-slip component 130 with the top screw 150, thereby ensuring the relative position stability of the anti-slip component 130 and the base 122, and avoiding the base 122 from swinging during the lifting and movement process and causing the battery pack 200 to swing.

[0051] refer to Figure 2 and Figure 5 The anti-slip component 130 includes an anti-slip rope 131 and two fixing buckles 132. The two ends of the anti-slip rope 131 cooperate with the two fixing buckles 132 to be bent to form two fixing loops 133. The two fixing loops 133 cooperate with the supporting component 120 and the hook component 300. By forming the fixing loops 133, the connection stability of the anti-slip rope 131, the top wire 150 and the hook component 300 can be avoided. The fixing buckles 132 are provided to lock the ends of the anti-slip rope 131 to prevent the fixing loops 133 from being easily untied.

[0052] refer to Figure 1 The embodiment of the utility model further provides a battery pack hoisting system 1000, including a battery pack 200, a hoisting member, and a hoisting sling 100, wherein the number of the hoisting slings 100 is at least two groups, and at least two groups of hoisting slings 100 are installed on the battery pack 200 and connected to the hoisting member. The battery pack hoisting system 1000 includes the hoisting sling 100, which has all the functions of the hoisting sling 100.

[0053] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
