Description

Technical Field

[0001] This application belongs to the field of battery technology, specifically relating to a battery pack lifting device. Background Technology

[0002] Battery packs are important components of electrical equipment (such as electric vehicles). During the manufacturing process, production personnel need to use cranes (or overhead cranes) and lifting equipment to lift and assemble battery packs.

[0003] In related technologies, existing battery pack lifting devices include a frame and a hook, with the hook connected to the frame via a chain, thus enabling the lifting of the battery pack. However, with these lifting devices, the hook's position is relatively fixed, which cannot accommodate the lifting needs of battery packs of different sizes. Utility Model Content

[0004] This application aims to provide a battery pack lifting device that can solve the problem that the lifting hook position of the lifting device used in related technologies is relatively fixed and cannot meet the lifting needs of battery packs of different sizes.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a battery pack lifting device, including a frame, at least two lifting components, and a first limiting component. The frame has a first direction, the lifting components are arranged along the first direction, and the lifting components slide on the frame for lifting the battery pack. The first limiting component is at least partially movable relative to the frame to switch between a limiting state and a releasing state. In the limiting state, the first limiting component extends at least partially toward the frame and engages with the frame for limiting. In the releasing state, the first limiting component separates from the frame to release the limiting.

[0007] Optionally, the first limiting component includes a mounting component and a limiting component, the mounting component being connected to the hoisting component, and the limiting component being movably connected to the mounting component and capable of switching between a first position and a second position relative to the mounting component;

[0008] The mounting component has a snap-fit ​​groove at one end away from the frame, the snap-fit ​​groove extending recessed toward the frame, and the limiting component extends out of the mounting component at one end away from the frame, the portion of the limiting component extending out of the mounting component having a snap-fit ​​protrusion.

[0009] When the limiting member is in the first position, the snap-fit ​​protrusion snaps into the snap-fit ​​groove, so that the limiting member at least partially extends out of the mounting member and engages with the frame for limiting;

[0010] When the limiting member is in the second position, the snap-fit ​​protrusion abuts against the end of the mounting member away from the frame, so that the end of the limiting member facing the frame is at least partially retracted until the mounting member releases its limiting effect on the frame.

[0011] Optionally, the frame is provided with a plurality of first limiting holes on the side facing the mounting member, and the plurality of first limiting holes are arranged at intervals along the first direction;

[0012] When the limiting member is in the first position, the limiting member can be inserted into any of the first limiting holes to limit the engagement with the frame.

[0013] Optionally, the first limiting component further includes an elastic element, the mounting member has a receiving cavity, the limiting element passes through the receiving cavity, one end of the elastic element is connected to the mounting member, and the other end of the elastic element is connected to the limiting element;

[0014] When the limiting member is in the second position, the elastic member is in a deformed state to provide a force toward the frame to the limiting member.

[0015] Optionally, the first limiting component further includes an operating member, which is connected to one end of the limiting member away from the frame, and the snap-fit ​​protrusion is connected to the side of the operating member facing the limiting member.

[0016] Optionally, the frame has a first direction and a second direction that are perpendicular to each other. The hoisting assembly includes a support member and at least two hook members. The support member is slidably connected to the frame along the first direction. The support member extends along the second direction and extends beyond both sides of the frame. At least two hook members are respectively disposed on both sides of the frame along the second direction. The hook members are slidably connected to the support member along the second direction.

[0017] Optionally, the mounting bracket includes a hanging ring portion and a mounting body portion, the hanging ring portion being slidably connected to the support member, the mounting body portion being connected to the hanging ring portion, and the mounting body portion being used to mount the battery pack.

[0018] Optionally, it further includes a second limiting component, which is connected to the lifting ring portion and is used to limit the support member and the lifting ring portion.

[0019] Optionally, the frame has a third direction, which is perpendicular to the first direction and the second direction. The hanging body includes a connector, a hook, and a pin. The connector is connected to the support member at one end along the third direction.

[0020] The hook includes a mounting plate and two clamping plates. The mounting plate is connected to the other end of the connector along the third direction. The two clamping plates are located on one side of the mounting plate and are spaced apart along the third direction. Both clamping plates are provided with through holes, and the pin is inserted into the two through holes.

[0021] Optionally, the main body of the hook also includes an anti-detachment component, which is disposed on the clamping plate near the connector. The anti-detachment component extends radially along the through hole and protrudes from the through hole. The pin has an anti-detachment groove extending in the third direction. The anti-detachment component cooperates with the anti-detachment groove to prevent the pin from being pulled out of the through hole.

[0022] In the embodiments of this application, at least two lifting assemblies are arranged along a first direction. The lifting assemblies slide against the frame. By changing the position of the lifting assemblies, the distance between the two assemblies can be changed, thereby enabling the lifting of battery packs of different sizes to meet the lifting requirements of different sized battery packs. After the lifting assemblies lift the battery pack, a first limiting assembly is operated to move at least partially relative to the frame, thereby placing the first limiting assembly in a limited state. This limits the lifting assemblies to the frame, preventing further movement of the lifting assemblies during the entire battery pack lifting process, thus preventing the battery pack from moving relative to the frame during lifting and improving the safety of battery pack lifting.

[0041] The battery pack lifting device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0042] like Figures 1 to 6 As shown, a battery pack lifting device according to some embodiments of this application includes a frame 10, at least two lifting assemblies 25, and a first limiting assembly 50. The frame 10 has a first direction X, the lifting assemblies 25 are arranged along the first direction X, the lifting assemblies 25 slide on the frame 10, and are used to lift the battery pack 01. The first limiting assembly 50 is at least partially movable relative to the frame 10 to switch between a limiting state and a releasing state. In the limiting state, the first limiting assembly 50 extends at least partially toward the frame 10 and engages with the frame 10 for limiting. In the releasing state, the first limiting assembly 50 separates from the frame 10 to release the limiting.

[0043] In the embodiments of this application, at least two lifting assemblies 25 are arranged along the first direction X. The lifting assemblies 25 slide on the frame 10. By changing the position of the lifting assemblies 25, the distance between the two lifting assemblies 25 can be changed, allowing for the lifting of battery packs 01 of different sizes to meet the lifting requirements of battery packs 01 of different sizes, thus possessing universality. After the lifting assembly 25 lifts the battery pack 01, the first limiting assembly 50 is operated to move at least partially relative to the frame 10, thereby placing the first limiting assembly 50 in a limited state, achieving the limitation between the lifting assembly 25 and the frame 10, preventing the lifting assembly 25 from moving during the entire movement of the battery pack lifting device, thereby preventing the battery pack 01 from moving relative to the frame 10 during the lifting process, and improving the safety of lifting the battery pack 01.

[0044] The frame 10 is a structure for mounting and supporting other components, and can be welded from profiles. The frame 10 has a first direction X, for example, the first direction X can be the length direction of the frame 10.

[0045] like Figure 1 and Figure 2 As shown, at least two lifting assemblies 25 are arranged along the first direction X. The lifting assemblies 25 slide on the frame 10, allowing the distance between the two lifting assemblies 25 to be changed. The lifting assemblies 25 are used to lift the battery pack 01, enabling the lifting of the battery pack 01.

[0046] The first limiting component 50 is at least partially movable relative to the frame 10, such that at least part of it can switch between a limiting state and a released state.

[0047] In the limited state, at least a portion of the first limiting component 50 extends toward the frame 10 and engages with the frame 10 for limiting, thereby limiting the lifting component 25 to the frame 10, and the lifting component 25 no longer moves along the first direction X.

[0048] In the released state, at least a portion of the first limiting component 50 separates from the frame 10, releasing the lifting component 25 from the frame 10 limit, allowing the lifting component 25 to continue moving along the first direction X. By switching at least a portion of the first limiting component 50 between the limiting state and the released state, the lifting component 25 can be limited or released from the frame 10.

[0049] Optionally, such as Figures 3 to 6As shown, the first limiting component 50 includes a mounting member 51 and a limiting member 53. The mounting member 51 is connected to the hoisting component 25, and the limiting member 53 is movably connected to the mounting member 51 and can switch between a first position and a second position relative to the mounting member 51. The mounting member 51 has a snap-fit ​​groove 512 at one end away from the frame 10, which extends recessed toward the frame 10. The limiting member 53 has a snap-fit ​​protrusion 531 at one end away from the frame 10. When the limiting member 53 is in the first position, the snap-fit ​​protrusion 531 snaps into the snap-fit ​​groove 512, so that the limiting member 53 at least partially extends out of the mounting member 51 and engages with the frame 10. When the limiting member 53 is in the second position, the snap-fit ​​protrusion 531 abuts against the end of the mounting member 51 away from the frame 10, so that the end of the limiting member 53 toward the frame 10 at least partially retracts back to the mounting member 51 and releases the limiting effect on the frame 10.

[0050] In this embodiment, the mounting member 51 is provided with a snap-fit ​​groove 512 at one end away from the frame 10, and the limiting member 53 is provided with a snap-fit ​​protrusion 531 at the part extending out of the mounting member 51. Through the cooperation of the snap-fit ​​protrusion 531 and the snap-fit ​​groove 512, the limiting member 53 can be switched between the first position and the second position, that is, the limiting state and the release state of the first limiting component 50 can be switched. The operation is convenient and the safety is high.

[0051] Specifically, such as Figures 3 to 6 As shown, the mounting member 51 is connected to the lifting assembly 25, thereby enabling the entire first limiting assembly 50 to be installed onto the lifting assembly 25. The limiting member 53 is movably connected to the mounting member 51 and can switch between a first position and a second position relative to the mounting member 51; for example, the limiting member 53 can be slidably connected to the mounting member 51. A snap-fit ​​groove 512 is provided at the end of the mounting member 51 facing away from the frame 10, and a snap-fit ​​protrusion 531 is provided on the portion of the limiting member 53 extending beyond the mounting member 51. The engagement of the snap-fit ​​protrusion 531 with the snap-fit ​​groove 512 enables the limiting member 53 to switch between the first position and the second position. When the limiting member 53 is in the first position, the snap-fit ​​protrusion 531 engages with the snap-fit ​​groove 512, causing the limiting member 53 to at least partially extend out of the mounting member 51 and engage with the frame 10, thus placing the first limiting assembly 50 in a limited state (i.e., Figure 3 and Figure 5 (As shown in the diagram). With the limiting member 53 in the second position, the engaging protrusion 531 abuts against the end of the mounting member 51 away from the frame 10, causing the limiting member 53 to retract at least partially towards the frame 10 until the mounting member 51 releases the limiting effect on the frame 10, thus putting the first limiting assembly 50 in the released state (i.e., Figure 4 and Figure 6 (The state shown).

[0052] Optionally, such as Figure 2 As shown, the frame 10 has a plurality of first limiting holes 11 on the side facing the mounting member 51, and the plurality of first limiting holes 11 are arranged at intervals along the first direction X; when the limiting member 53 is in the first position, the limiting member 53 can be inserted into any of the first limiting holes 11 so that the limiting member 53 is in a limiting engagement with the frame 10.

[0053] In this embodiment, the limiting member 53 is inserted into the first limiting hole 11 to achieve the limiting of the frame 10, making the limiting of the frame 10 more reliable. Even if the hoisting component 25 is subjected to an external force along the first direction X, it will not slide relative to the frame 10 again, thus ensuring the reliability of the limiting of the hoisting component 25.

[0054] Specifically, such as Figure 2 As shown, the frame 10 has a plurality of first limiting holes 11 on the side facing the receiving member. The plurality of first limiting holes 11 are arranged at intervals along the first direction X. When the hoisting assembly 25 moves into place along the first direction X, the limiting member 53 is inserted into the first limiting hole 11 to limit the position of the limiting member 53 and the frame 10. For example, the intervals between adjacent first limiting holes 11 along the first direction X can be equal.

[0055] Optionally, such as Figure 4 and Figure 6 As shown, the first limiting component 50 also includes an elastic member 52, the mounting member 51 has a receiving cavity 511, the limiting member 53 passes through the receiving cavity 511, one end of the elastic member 52 is connected to the mounting member 51, and the other end of the elastic member 52 is connected to the limiting member 53; when the limiting member 53 is in the second position (i.e. Figure 6 (as shown in the figure), the elastic element 52 is in a deformed state to provide a force toward the frame 10 to the limiting element 53.

[0056] In this embodiment, the receiving cavity 511 of the mounting member 51 can accommodate the elastic member 52. One end of the elastic member 52 is connected to the mounting member 51, and the other end of the elastic member 52 is connected to the limiting member 53. When an external force is applied to the limiting member 53 away from the frame 10, the limiting member 53 moves away from the frame 10, and the elastic member 52 deforms, thereby releasing the limiting position and causing the locking protrusion 531 to abut against the end of the mounting member 51 away from the frame 10. When the external force is removed, the limiting member 53 can automatically move closer to the frame 10 under the rebound action of the elastic member 52, thereby achieving the limiting position with the frame 10.

[0057] Specifically, such as Figure 4 and Figure 6As shown, the first limiting component 50 also includes an elastic element 52. The mounting component 51 has a receiving cavity 511, and the limiting element 53 passes through the receiving cavity 511. One end of the elastic element 52 is connected to the mounting component 51, and the other end of the elastic element 52 is connected to the limiting element 53. When the limiting element 53 moves away from the frame 10, the elastic element 52 undergoes elastic deformation, and the locking protrusion 531 separates from the locking groove 512. The limiting element 53 is rotated, for example, by 90 degrees, so that the locking protrusion 531 abuts against the end of the mounting component 51 away from the frame 10, thereby preventing the limiting element 53 from re-limiting the frame 10, and the hoisting component 25 can move. After the hoisting component 25 moves into place, the limiting element 53 is rotated again to align the locking protrusion 531 with the locking groove 512. The external force is removed, and the locking protrusion 531 re-engages with the locking groove 512 under the rebound action of the elastic element 52, and the limiting element 53 re-limits the frame 10.

[0058] It should be noted that, as Figure 7 As shown, the mounting member 51 has a receiving cavity 511, thereby forming a cylindrical structure. The limiting member 53 passes through the receiving cavity 511. The elastic member 52 can also be configured as a cylindrical structure; for example, the elastic member 52 can be a spring. The limiting member 53 also passes through the elastic member 52. For example, as shown... Figure 6 and Figure 8 As shown, an annular protrusion can be provided on the limiting member 53, and the spring is connected to the annular protrusion, thereby facilitating the connection between the spring and the limiting member 53.

[0059] Optionally, such as Figure 8 As shown, the first limiting component 50 also includes an operating member 54, which is connected to the end of the limiting member 53 away from the frame 10, and a snap-fit ​​protrusion 531 is connected to the side of the operating member 54 facing the limiting member 53.

[0060] In this embodiment, by providing an operating member 54 at the end of the limiting member 53 away from the frame 10, it is convenient for the operator to hold the entire limiting member 53, thereby realizing the outward pulling operation of the limiting member 53, reducing the difficulty of operation, and improving the ease of use of the first limiting component 50.

[0061] Specifically, such as Figure 8 As shown, the operating component 54 is connected to the end of the limiting component 53 that is away from the frame 10. For example, the operating component 54 can be a ball handle, a disc handle, or other components, which makes it convenient for the operator to hold and thus facilitates the operator to apply force.

[0062] For example, the operating member 54 is detachably connected to the limiting member 53, allowing the limiting member 53 to be installed into the receiving cavity 511 first, and then the operating member 54 to be installed into the limiting member 53, reducing the installation difficulty of the limiting member 53. For instance, a threaded hole can be formed at the end of the limiting member 53 facing away from the frame 10, and a threaded shaft can be formed at the end of the operating member 54 facing the frame 10, thereby achieving the installation of the operating member 54 and the limiting member 53 through a threaded connection.

[0063] Optionally, such as Figure 1 and Figure 2 As shown, the frame 10 has a first direction X and a second direction Y that are perpendicular to each other. The hoisting assembly 25 includes a support member 30 and at least two hook members 40. The support member 30 is slidably connected to the frame 10 along the first direction X. The support member 30 extends along the second direction Y and extends beyond both sides of the frame 10. The at least two hook members 40 are respectively disposed on both sides of the frame 10 along the second direction Y. The hook members 40 are slidably connected to the support member 30 along the second direction Y.

[0064] In this embodiment, the support member 30 is slidably connected to the frame 10 along the first direction X, and at least two hook members 40 are respectively disposed on both sides of the frame 10 along the second direction Y. The hook members 40 are slidably connected to the support member 30 along the second direction Y, so that the hook members 40 can move simultaneously along the first direction X and the second direction Y, thereby further expanding the size range of the battery pack 01 that the hook members 40 can hook.

[0065] Specifically, such as Figure 1 and Figure 2 As shown, the frame 10 forms a cuboid structure with three perpendicular directions: a first direction X, a second direction Y, and a third direction Z. The first direction X can be the length direction of the frame 10, the second direction Y can be the width direction of the frame 10, and the third direction Z can be the height direction of the frame 10. A support member 30 is slidably connected to the frame 10 along the first direction X, and extends along the second direction Y beyond both sides of the frame 10. At least two hooks 40 are slidably connected along the second direction Y to the portions of the support member 30 extending beyond the frame 10. Thus, the battery pack lifting device has at least four hooks 40, allowing the battery pack 01 to be hooked from at least four positions, achieving stable hooking and lifting of the battery pack 01.

[0066] It should be noted that a guide member 20 extending along the first direction X can be provided on the frame 10, such as a guide rail or optical axis. The support member 30 can slide relative to the guide member 20. At the same time, a slider or other component can be provided on the support member 30 to cooperate with the guide member 20, ensuring that the support member 30 slides smoothly relative to the frame 10 and reducing the possibility of jamming.

[0067] like Figure 2As shown, to facilitate the installation of the first limiting component 50, a support plate 31 can be installed on the side of the support member 30 facing the frame 10 along the third direction Z. The support plate 31 is spaced apart from the frame 10 along the second direction Y. Then, the mounting part 51 of the first limiting component 50 is installed onto the support plate 31, thereby realizing the installation of the first limiting component 50. In addition, in the released state, the limiting member 53 is completely pulled out from the first limiting hole 11, and there is a gap between the limiting member 53 and the frame 10, so as not to affect the movement of the support member 30 relative to the frame 10 along the first direction X.

[0068] It should be noted that, as Figure 2 As shown, the first limiting hole 11 can be an elongated hole extending along the third direction Z, so that the limiting member 53 can be easily inserted into the first limiting hole 11. Moreover, the elongated hole extending along the third direction Z can also allow the lifting assembly 25 to make slight movements due to the gravity of the battery pack 01 after lifting the battery pack 01.

[0069] Optionally, such as Figure 9 As shown, the mounting bracket 40 includes a hanging ring portion 41 and a mounting body portion 42. The hanging ring portion 41 is slidably connected to the support member 30, and the mounting body portion 42 is connected to the hanging ring portion 41. The mounting body portion 42 is used to mount the battery pack 01.

[0070] In this embodiment, the sliding connection between the lifting ring 41 and the support member 30 is achieved through the lifting ring part 41, which has a simple structure and low manufacturing cost.

[0071] Specifically, such as Figure 2 and Figure 9 As shown, the hanger 40 includes a hanging ring portion 41 and a hanger body portion 42. The hanging ring portion 41 is slidably connected to the portion of the support member 30 that extends beyond the frame 10, and the hanger body portion 42 is connected to the hanging ring portion 41, thereby realizing the slidable connection of the hanger body portion 42 relative to the support member 30.

[0072] It should be noted that there is a gap between the lifting ring 41 and the support member 30 to facilitate sliding and ensure smooth sliding. For example, a guide component can also be provided between the lifting ring 41 and the support member 30 to further improve the smoothness of the sliding of the lifting ring 41.

[0073] Optionally, such as Figure 2 As shown, the battery pack lifting device also includes a second limiting component 60, which is connected to the lifting ring part 41 and is used to limit the support member 30 and the lifting ring part 41.

[0074] In this embodiment of the application, the second limiting component 60 is used to limit the lifting ring 41 and the support member 30, so as to ensure that the lifting ring 41 will not slide after it moves into place, thus ensuring the reliability of the lifting.

[0075] Specifically, such as Figure 2 As shown, the battery pack lifting device also includes a second limiting component 60, which is disposed on the lifting ring portion 41. The second limiting component 60 can limit the support member 30 and the lifting ring portion 41, thereby preventing the lifting ring portion 41 from continuing to slide relative to the support member 30.

[0076] For example, the structure of the second limiting component 60 can be the same as that of the first limiting component 50. On the one hand, this can reduce the number of types of materials and reduce the difficulty of material management; on the other hand, it can achieve the same limiting effect as the first limiting component 50. Of course, the second limiting component 60 can also have other structures, which can be flexibly set according to the actual situation. This application embodiment does not limit this.

[0077] Optionally, such as Figure 2 and Figure 10 As shown, the frame 10 has a third direction Z, which is perpendicular to the first direction X and the second direction Y. The main body 42 includes a connector 43, a hook 44 and a pin 45. One end of the connector 43 along the third direction Z is connected to the support 30. The hook 44 includes a mounting plate 441 and two clamping plates 442. The mounting plate 441 is connected to the other end of the connector 43 along the third direction Z. The two clamping plates 442 are located on one side of the mounting plate 441 and are spaced apart along the third direction Z. Both clamping plates 442 are provided with through holes, and the pin 45 is inserted into the two through holes.

[0078] In this embodiment, the hook 44 forms a snap-fit ​​component for snapping onto the edge plate 02 of the battery pack 01. The hook 44 snaps onto the edge plate 02 of the battery pack 01. The edge plate 02 of the battery pack 01 is provided with a socket, which is opposite to the through hole. Then, the pin 45 is inserted into the socket and the through hole to realize the hook 44 and the edge plate 02 of the battery pack 01.

[0079] Specifically, such as Figure 2 and Figure 10 As shown, one end of the connector 43 is connected to the support member 30, and the other end is connected to the mounting plate 441 of the hook 44, thus connecting the hook 44 to the support member 30. Two clamping plates 442 are connected to the mounting plate 441, forming a structure that snaps onto the edge plate 02 of the battery pack 01. Exemplarily, the connector 43 can be a component such as an iron chain, nylon strap, or fiber strap, which enables the connection between the support member 30 and the hook 44, and can bend and shift itself to facilitate the connection between the hook 44 and the edge plate 02 of the battery pack 01.

[0080] Optionally, such as Figure 9As shown, the main body 42 also includes an anti-detachment member 46. The anti-detachment member 46 is provided on the clamping plate 442 near the connector 43. The anti-detachment member 46 extends radially along the through hole and protrudes out of the through hole. The pin 45 is provided with an anti-detachment groove 451 extending in the third direction Z. The anti-detachment member 46 cooperates with the anti-detachment groove 451 to prevent the pin 45 from being pulled out of the through hole.

[0081] In this embodiment, the portion of the anti-detachment member 46 protruding from the through hole engages with the anti-detachment groove 451 on the pin 45. The pin 45 can move normally along the third direction Z. Due to the engagement between the anti-detachment member 46 and the anti-detachment groove 451, the pin 45 will not be pulled out of the through hole, so that the pin 45 will not separate from the hook 44, thereby achieving the anti-detachment of the pin 45 and preventing the pin 45 from falling off and being lost.

[0082] Specifically, such as Figure 9 As shown, the main body 42 also includes an anti-detachment component 46. The anti-detachment component 46 is located near the clamping plate 442 of the connector 43, that is, the upper clamping plate 442. The anti-detachment component 46 extends radially along the through hole and protrudes from the through hole. The pin 45 has an anti-detachment groove 451 extending in the third direction Z. The anti-detachment component 46 cooperates with the anti-detachment groove 451 to prevent the pin 45 from being pulled out of the through hole. When the pin 45 is pulled to the upper clamping plate 442 position, the pin 45 separates from the edge plate 02 of the battery pack 01, so that the entire hook 44 can be separated from the edge plate 02 of the battery pack 01. However, due to the engagement of the anti-detachment component 46 and the anti-detachment groove 451, the pin 45 will not be pulled out of the through hole, so that the pin 45 will not be separated from the hook 44.

[0083] Optionally, the main body 42 may also include a protective layer covering the surface of the hook 44.

[0084] In this embodiment, the protective layer covers the surface of the hook 44, that is, the outer surface of the mounting plate 441 and the two clamping plates 442. When the battery pack 01 is attached, the protective layer contacts the edge plate 02 of the battery pack 01 to protect the battery pack 01.

[0085] Specifically, the main body 42 also includes a protective layer that covers the surface of the hook 44. For example, the protective layer can be a soft material such as rubber or sponge, which will not damage the edge plate 02 of the battery pack 01 when it comes into contact with it. Of course, the protective layer can also be made of other types of materials, and can be flexibly set according to actual conditions; this application embodiment does not limit this.

[0086] In addition, such as Figure 1As shown, a handrail 12 can also be installed on the frame 10 to facilitate the operator's support of the frame 10. The lifting and lowering operation of the battery pack hoisting device can be achieved through the overhead crane controller 13. To facilitate the placement of the overhead crane controller 13, a clamp can be installed on the frame 10 to place the overhead crane controller 13 in the clamp for easy operation by the operator.
