The first end is provided with a positioning part, the second end is provided with an elastic part, and a connecting part passes through the second main body and is located between the first end and the second end. The first direction and the second direction intersect.

[0006] In some embodiments, the positioning portion includes a positioning pin, which passes through a first mounting hole in the second body portion and protrudes from the side of the second body portion facing the first mounting portion.

[0009] In some embodiments, the first mounting portion includes a hook portion, one end of which is connected to the connecting portion, and the other end of which extends toward the positioning portion.

[0010] According to a second aspect of this application, this application provides a battery pack, comprising: Battery pack; Multiple end plates are spaced apart, with the battery pack positioned between two adjacent end plates; the end plates are used for detachable connection with the aforementioned hoisting fixture.

[0011] In some embodiments, a second mounting hole is provided on one side of the end plate along the first direction, the second mounting hole being used to accommodate the positioning part of the lifting fixture; A third mounting hole is provided on the side of the end plate away from the battery pack. The third mounting hole is used to accommodate the first mounting part of the hoisting tool.

[0012] In some embodiments, the battery pack includes a cable tie, which is sleeved on the outer periphery of the end plate and the battery pack. The end plate has a plurality of limiting portions, at least two of which are spaced apart along a first direction. The cable tie is connected to the limiting portions on both sides along the first direction.

[0013] In some embodiments, the battery pack includes a protective layer that covers at least a portion of the cable ties.

[0014] The hoisting fixture of this application includes a first main body, a second main body, a connecting part, a positioning part, and an elastic part. The second main body and the first main body are spaced apart along a first direction. The connecting part connects the first main body and the second main body, and a first mounting part is provided on one side of the connecting part for connecting to a battery pack. The positioning part is connected to the second main body, and the positioning part and the first mounting part are arranged opposite to each other along the first direction.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0021] The applicant noted that as the energy density of energy storage systems gradually increases and energy storage modules develop towards larger capacities, these modules contain some precision components that require extremely high stability during handling. Currently, the primary method of handling energy storage modules is manual labor combined with simple lifting equipment, which carries the risk of uneven stress, structural deformation, and module detachment.

[0022] In view of this, this application provides a lifting fixture, including a first main body 1, a second main body 2, a connecting part 3, a positioning part 4, and an elastic part 5. The second main body 2 and the first main body 1 are spaced apart along a first direction X. The connecting part 3 connects the first main body 1 and the second main body 2, and a first mounting part 30 is provided on one side of the connecting part 3 for connecting to a battery pack. The positioning part 4 is connected to the second main body 2, and is positioned opposite to the first mounting part 30 along the first direction X, for connecting to the battery pack. The elastic part 5 connects the second main body 2 and the first main body 1 respectively, and is spaced apart from the positioning part 4, for controlling the movement of the second main body 2 and the positioning part 4 along the first direction X. This application sets the first mounting part 30 to be fixed to the battery pack, and controls the connection and disassembly of the positioning part 4 and the battery pack by adjusting the extension and retraction of the elastic part 5. This simplifies the loading and unloading process of the lifting fixture and the battery pack, further improves the connection stability of the lifting fixture and the battery pack, prevents the battery pack from falling off during lifting, and improves the safety factor. Furthermore, the elastic part 5 and the positioning part 4 are spaced apart. On the one hand, after the force of the elastic part 5 acts on the second main body 2, the second main body 2 drives the positioning part 4 to achieve displacement, ensuring the connection accuracy and stability between the positioning part 4 and the battery pack. On the other hand, positioning parts 4 and elastic parts 5 of different sizes can be replaced according to the parameters of the battery pack, thereby improving the adaptability of the lifting fixture and reducing costs. This application embodiment also provides a battery pack, including a battery group 100 and multiple end plates 101, with the multiple end plates 101 spaced apart. The battery group 100 is disposed between two adjacent end plates 101. The end plates 101 are used for detachable connection with the aforementioned lifting fixture. The end plates 101 can act as a connecting carrier, providing a stable connection point for the lifting fixture. This arrangement eliminates the need for additional connecting carriers for the installation fixture, saving space and avoiding structural damage caused by directly setting lifting points on the battery group 100. Simultaneously, the rigid structure of the end plates 101 can disperse the lifting force, preventing the battery group 100 from deforming due to uneven force.

[0023] The lifting fixture and battery pack of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementation methods can be combined with each other.

[0024] Reference Figure 1This application provides a hoisting fixture, including a first main body 1, a second main body 2, a connecting part 3, a positioning part 4, and an elastic part 5. The second main body 2 and the first main body 1 are spaced apart along a first direction X. The connecting part 3 connects the first main body 1 and the second main body 2. A first mounting part 30 is provided on one side of the connecting part 3, which is used to connect to a battery pack. The positioning part 4 is connected to the second main body 2 and is positioned opposite to the first mounting part 30 along the first direction X. The positioning part 4 is used to connect to the battery pack. The elastic part 5 connects the second main body 2 and the first main body 1 respectively. The elastic part 5 is spaced apart from the positioning part 4 and is used to control the movement of the second main body 2 and the positioning part 4 along the first direction X.

[0025] Specifically, refer to Figure 2 and Figure 3 The first direction X is the height direction. The end plate 101 of the battery pack is provided with a second mounting hole 1010 on one side along the first direction X. The second mounting hole 1010 is used to accommodate the positioning part 4 of the hoisting tool. The end plate 101 is provided with a third mounting hole 1011 on the side away from the battery pack 100. The third mounting hole 1011 is used to accommodate the first mounting part 30 of the hoisting tool. By pressing the elastic part 5, the elastic part 5, under pressure, moves the second main body 2 and the positioning part 4 along the first direction X toward the side away from the first mounting part 30, causing the positioning part 4 to retract from its initial position to avoid interference with the end plate 101. This engages the first mounting part 30 into the third mounting hole 1011 of the end plate 101. Then, by releasing the elastic part 5, the restoring force of the elastic part 5 moves the second main body 2 and the positioning part 4 along the first direction X toward the side facing the first mounting part 30, returning the positioning part 4 to its initial position. This allows the positioning part 4 to be inserted into the second mounting hole 1010 of the end plate 101, thereby improving the connection stability between the lifting fixture and the battery pack. When the battery pack reaches the target position, pressing the elastic part 5 again drives the positioning part 4 to move along the first direction X and exit from the second mounting hole 1010 of the end plate 101. After releasing the constraint of the positioning part 4, the first mounting part 30 is removed from the third mounting hole 1011 of the end plate 101, completing the separation of the lifting fixture from the battery pack.

[0026] This application sets the first mounting part 30 to be fixed to the battery pack, and controls the connection and disassembly of the positioning part 4 and the battery pack by adjusting the extension and retraction of the elastic part 5. This simplifies the loading and unloading process of the lifting fixture and the battery pack, while further improving the connection stability between the lifting fixture and the battery pack, preventing the battery pack from falling off during lifting, and increasing the safety factor. Furthermore, the elastic part 5 and the positioning part 4 are spaced apart. On one hand, the force of the elastic part 5 acts on the second main body 2, causing the second main body 2 to drive the positioning part 4 to move, ensuring the connection accuracy and stability between the positioning part 4 and the battery pack. On the other hand, different sizes of the positioning part 4 and the elastic part 5 can be replaced according to the parameters of the battery pack, thereby improving the adaptability of the lifting fixture and reducing costs.

[0027] In some embodiments, the second main body 2 includes a first end 20 and a second end 21 disposed opposite to each other along a second direction Y. The first end 20 is provided with a positioning part 4, and the second end 21 is provided with an elastic part 5. A connecting part 3 passes through the second main body 2 and is located between the first end 20 and the second end 21. The first direction X and the second direction Y intersect. The first direction X is a height direction, and the second direction Y is a horizontal direction. Figure 1 In the illustrated embodiment, the second direction Y is the length direction of the second main body 2. A positioning part 4 is disposed at the first end 20, an elastic part 5 is disposed at the second end 21, and a connecting part 3 passes between them, forming a lever structure with the connecting part 3 as a fulcrum. When the elastic part 5 is pressed and released along the first direction X, the force generated by the elastic part 5 can drive the second main body 2 to move along the first direction X, thereby driving the positioning part 4 connected to the second main body 2 to move. This arrangement makes operation easier; workers can quickly drive the positioning part 4 to insert or withdraw along the first direction X into or out of the second mounting hole 1010 of the end plate 101 by simply pressing the elastic part 5, shortening loading and unloading time.

[0028] In some embodiments, refer to Figure 1 The positioning part 4 includes a positioning pin 40. The second main body 2 has a first mounting hole. The positioning pin 40 passes through the first mounting hole and protrudes from the side of the second main body 2 facing the first mounting part 30. After the positioning pin 40 passes through the first mounting hole, the protruding part of the positioning pin 40 can be precisely aligned with the second mounting hole 1010 of the end plate 101. It can be understood that when the elastic part 5 is subjected to force, it drives the second main body 2 and the positioning pin 40 to move away from the first mounting part 30 along the first direction X, avoiding interference between the positioning pin 40 and the end plate 101, thereby facilitating the insertion of the first mounting part 30 into the third mounting hole 1011 of the end plate 101. The positioning pin 40 and the first mounting part 30 are arranged opposite each other along the first direction X, and the two form constraints from different positions on the end plate 101, avoiding the problem of battery pack tilting or falling off due to uneven force.

[0029] In some embodiments, refer to Figure 1The positioning pin 40 is movably connected to the second main body 2. The positioning part 4 includes a nut 41, which is threadedly connected to the positioning pin 40. The positioning pin 40 is movably connected to the second main body 2, and its length protruding from the second main body 2 can be changed by the nut 41, thereby adapting to end plates 101 of different sizes and ensuring that the positioning pin 40 can be stably engaged in the second mounting hole 1010 of the end plate 101.

[0030] In some embodiments, refer to Figure 4 The lifting fixture includes a lifting device 6; a second mounting part 31 is provided at the end of the connecting part 3 away from the first mounting part 30, and the second mounting part 31 is connected to the lifting device 6. The connecting part 3 is connected to the end plate 101 of the battery pack through the first mounting part 30, and to the lifting device 6 through the second mounting part 31. Furthermore, multiple lifting holes can be provided on the end plate 101, as shown in the reference... Figure 5 Two second mounting holes 1010 and two third mounting holes 1011 are provided at intervals on an end plate 101, and are respectively connected to the first mounting part 30 and the positioning part 4. This can distribute the pulling force of the lifting device 6 to the end plate 101, and avoid problems such as structural deformation, battery pack tilting or falling off caused by excessive local stress.

[0031] In some embodiments, refer to Figure 1 , Figure 2 and Figure 3 The first mounting part 30 includes a hook part 300, one end of which is connected to the connecting part 3, and the other end of which extends toward the positioning part 4. The hook part 300 can hook onto the edge of the third mounting hole 1011 of the end plate 101, and the connection between the hook part 300 and the battery pack is achieved by the weight of the battery pack. In addition, by providing the positioning part 4, a stable connection between the battery pack and the lifting fixture can be achieved.

[0032] Reference Figure 4 and Figure 6 This application also provides a battery pack, including a battery pack 100 and multiple end plates 101. The multiple end plates 101 are spaced apart, and the battery pack 100 is disposed between two adjacent end plates 101. The end plates 101 are used for detachable connection with the aforementioned lifting fixture. The end plates 101 can act as a connecting carrier, providing a stable connection point for the lifting fixture. This arrangement eliminates the need for additional connecting carriers for the installation fixture, saving space and avoiding structural damage caused by directly setting lifting points on the battery pack 100. At the same time, the rigid structure of the end plates 101 can distribute the lifting force, preventing the battery pack 100 from deforming due to uneven force.

[0033] In some embodiments, refer to Figure 5The end plate 101 has a second mounting hole 1010 on one side along the first direction X, which is used to accommodate the positioning part 4 of the lifting fixture; the end plate 101 has a third mounting hole 1011 on the side away from the battery pack 100, which is used to accommodate the first mounting part 30 of the lifting fixture. (Refer to...) Figure 2 and Figure 3 By pressing the elastic part 5, the elastic part 5, under force, drives the second main body 2 and the positioning part 4 to move away from the first mounting part 30 along the first direction X, causing the positioning part 4 to retract from its initial position to avoid interference with the end plate 101. The first mounting part 30 is then inserted into the third mounting hole 1011 of the end plate 101. Subsequently, the elastic part 5 is released, and the restoring force of the elastic part 5 drives the second main body 2 and the positioning part 4 to move towards the first mounting part 30 along the first direction X, causing the positioning part 4 to return to its initial position. This allows the positioning part 4 to be inserted into the second mounting hole 1010 of the end plate 101, thereby improving the connection stability between the hoisting fixture and the battery pack. After the battery pack moves to the target position, press the elastic part 5 again to drive the positioning part 4 to move along the first direction X and exit from the second mounting hole 1010 of the end plate 101; after releasing the constraint of the positioning part 4, remove the first mounting part 30 from the third mounting hole 1011 of the end plate 101 to complete the separation of the hoisting fixture from the battery pack.

[0034] This application sets the first mounting part 30 to be fixed to the battery pack, and controls the connection and disassembly of the positioning part 4 and the battery pack by adjusting the extension and retraction of the elastic part 5. This simplifies the loading and unloading process of the lifting fixture and the battery pack, while further improving the connection stability between the lifting fixture and the battery pack, preventing the battery pack from falling off during lifting, and increasing the safety factor. Furthermore, the elastic part 5 and the positioning part 4 are spaced apart. On one hand, the force of the elastic part 5 acts on the second main body 2, causing the second main body 2 to drive the positioning part 4 to move, ensuring the connection accuracy and stability between the positioning part 4 and the battery pack. On the other hand, different sizes of the positioning part 4 and the elastic part 5 can be replaced according to the parameters of the battery pack, thereby improving the adaptability of the lifting fixture and reducing costs.

[0035] In some embodiments, refer to Figure 7 The battery pack includes cable ties 102, which are sleeved on the outer periphery of the end plate 101 and the battery pack 100. The end plate 101 has multiple limiting portions 1012, with at least two limiting portions 1012 spaced apart along a first direction X. The cable ties 102 are connected to the limiting portions 1012 on both sides along the first direction X. By providing cable ties 102, the loosening of the battery pack 100 structure caused by vibration and impact during handling or use can be reduced, thereby improving the stability and reliability of the battery pack.

[0036] In some embodiments, the battery pack includes a protective layer 103 that covers at least a portion of the cable tie 102. (See also...) Figure 7 The protective layer 103 is disposed on the outer periphery of the battery pack 100, which can prevent the cable ties 102 from directly contacting the outer shell of the battery pack 100 during handling, installation or long-term use, which may cause scratches or cause local deformation of the outer shell due to the concentration of restraint stress, thereby enhancing the protective effect on the battery pack 100.
