Description

Technical Field

[0001] This invention relates to the field of battery swapping technology, and more particularly to a battery swapping device, a battery swapping forklift, and a battery swapping station. Background Technology

[0002] With the rapid development of battery swapping technology, more and more battery swapping light trucks are being put into operation. In the past, the battery packs of battery swapping light trucks were usually arranged on both sides of the frame. However, this arrangement can easily lead to higher vehicle costs. In order to reduce vehicle costs and improve vehicle performance, battery swapping light trucks now usually adopt a single-pack bottom solution, that is, the battery pack is installed at the bottom of the battery swapping light truck.

[0003] In related technologies, battery swapping forklifts are typically used for battery swapping on light trucks with battery packs installed at the bottom. These forklifts have a swapping platform mounted on their forks, which is used to lift and lower the battery pack. However, because these light trucks are cargo vehicles, their body posture is easily affected by the cargo, causing them to tilt. Since the battery pack is installed at the bottom of the truck, its posture also tilts. When the battery pack is tilted, the swapping platform is not parallel to the lower surface of the battery pack. Therefore, during battery swapping, one side of the battery pack may contact the swapping platform while the other side is suspended in the air. This can cause the suspended battery pack to fall during the swapping process, easily damaging the battery pack and significantly reducing its safety performance. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the first objective of this invention is to provide a battery swapping device for battery swapping trucks. By setting multiple floating adjustment components, it ensures that the first support member is in close contact with the lower surface of the battery pack during the docking process, preventing the battery pack from being suspended in the air during the swapping process, thereby avoiding the battery pack falling and being damaged, and greatly improving the reliability and safety of battery pack replacement.

[0005] The second objective of this invention is to provide a battery-swapping forklift.

[0006] The third objective of this invention is to propose a battery swapping station.

[0007] To achieve the above objectives, a first aspect of the present invention provides a battery swapping device for a battery swapping forklift, characterized in that the battery swapping device is adapted to be fixed to the battery swapping forklift, the battery swapping forklift is used to drive the battery swapping device to lift and lower, and the battery swapping device includes:

[0008] The first support member is used to place the battery pack;

[0009] The second support member and the first connector are located on the side of the first support member away from the battery pack and spaced apart from the first support member, and the first connector is connected between the first support member and the second support member.

[0010] Multiple floating adjustment components are provided, each of which is located on the second support member and on the side of the second support member away from the first support member. Each of the multiple floating adjustment components is adapted to be connected to the battery swapping forklift, and each floating adjustment component is movable along the lifting direction of the battery swapping device.

[0011] According to an embodiment of the present invention, a battery swapping device for a battery swapping forklift involves the battery swapping forklift driving the device to move toward the battery pack during the swapping process, causing the battery pack to dock with a first support member. During docking, the battery pack applies pressure to the first support member, driving a second support member to compress a floating adjustment component via a first connector. This causes the floating adjustment component to move toward the battery swapping forklift. When the battery pack is tilted, the force on the first support member and the battery pack is uneven during docking, resulting in different pressures on the multiple floating adjustment components. Consequently, the distances the multiple floating adjustment components move toward the battery swapping forklift are also different, allowing the first support member to remain tilted. This ensures that the first support member is parallel to the lower surface of the battery pack during docking, preventing the battery pack from becoming suspended during the swapping process and thus avoiding damage from falling. This significantly improves the reliability and safety of battery pack replacement.

[0012] According to one embodiment of the present invention, it further includes: a locking component, the locking component being movably disposed on the first support member, and the locking component having a first position and a second position relative to the first support member.

[0049] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0050] The following description, with reference to the accompanying drawings, describes a battery swapping device 100, a battery swapping forklift 200, and a battery swapping station according to embodiments of the present invention. The battery swapping device 100 can be applied to the battery swapping forklift 200, but this application is not limited thereto. The battery swapping device 100 can be applied to other equipment that requires the installation of the battery swapping device 100. In this invention, the application of the battery swapping device 100 to the battery swapping forklift 200 is used as an example for illustration.

[0051] The battery swapping forklift 200 has a battery swapping device 100. The forklift 200 replaces the battery pack at the bottom of the truck by driving the lifting and lowering of the battery swapping device 100, greatly improving the battery pack replacement efficiency. Figure 1 As shown, in some embodiments of the present invention, the forklift body 201 of the battery swapping forklift 200 has forks 202, and the battery swapping device 100 is fixedly installed on the forks 202. The installation method includes, but is not limited to, bolt connection. With this configuration, the battery swapping device 100 can be docked with the battery pack at the bottom of the battery swapping truck by driving the lifting and lowering of the forks 202 of the battery swapping forklift 200, which facilitates the replacement of the battery pack and improves the replacement efficiency of the battery pack.

[0052] like Figures 1-7 As shown, the battery swapping device 100 according to a first aspect embodiment of the present invention includes: a first support member 1, a second support member 2, a first connector 3, and a plurality of floating adjustment components 4. The first support member 1 is used to place a battery pack, the second support member 2 is located on the side of the first support member 1 away from the battery pack and spaced apart from the first support member 1, the first connector 3 connects between the first support member 1 and the second support member 2, and the plurality of floating adjustment components 4 are all disposed on the second support member 2 and located on the side of the second support member 2 away from the first support member 1. The plurality of floating adjustment components 4 are all adapted to be connected to a battery swapping forklift, and each floating adjustment component 4 is movable along the lifting direction of the battery swapping device 100.

[0053] Specifically, refer to Figure 2 and Figure 6 As shown, both the first support member 1 and the second support member 2 can be constructed as support plates. The first support member 1 has multiple support legs 16, each of which is fixedly connected to a corresponding first connector 3. That is, the first connector 3 connects the second support member 2 and the corresponding support leg 16 of the first support member 1. It should be noted that the first connector 3 is located below the second support member 2, and the length of each support leg 16 is greater than the length of the corresponding first connector 3. This arrangement ensures that the second support member 2 is located on the side of the first support member 1 away from the battery pack and is spaced apart from the first support member 1, thus placing the second support member 2 below the first support member 1 and spaced apart from it. For example, as... Figure 2 As shown, taking the first support member 1 with 4 support legs 16 as an example, the 4 support legs 16 are fixedly connected to the corresponding first connecting members 3 respectively, and the length of the 4 support legs 16 is greater than the length of the corresponding first connecting members 3. With this setting, the second support member 2 can support the first support member 1 through the cooperation of the 4 support legs 16 and the 4 first connecting members 3.

[0054] It should be noted that the first connecting member 3 can be a rigid connecting member or a flexible connecting member. In some embodiments of the present invention, the first connecting member 3 is described as a flexible connecting member. For example, the first connecting member 3 can be constructed as a suspension chain, that is, the second support member 2 is fixedly connected to the four support legs 16 of the first support member 1 through four suspension chains. With this configuration, when the battery swapping device 100 docks with the battery pack, the first support member 1 and the battery pack can be docked in a floating manner, avoiding serious collisions between the battery pack and the first support member 1, which is beneficial to improving the safety performance of the battery pack.

[0055] Furthermore, such as Figure 2 and Figure 4 As shown, multiple floating adjustment components 4 are provided below the second support member 2, for reference. Figure 1 As shown, multiple floating adjustment components 4 are fixedly installed on the forks 202 of the battery swapping forklift. With this configuration, by driving the forks 202 to rise or fall, the floating adjustment components 4 can drive the first support 1 and the second support 2 to rise or fall, thus achieving the overall lifting of the battery swapping device 100. Furthermore, each floating adjustment component 4 is movable along the lifting direction of the battery swapping device 100; that is, each floating adjustment component 4 is vertically adjustable between the second support 2 and the forks 202 to change the distance between the second support 2 and the forks 202 at both ends of the floating adjustment component 4.

[0056] As a specific example, when the battery swapping forklift drives the battery swapping device 100 to lift and lower to replace the battery pack at the bottom of the battery swapping truck, the forklift drives the battery swapping device 100 to move towards the battery pack, so that the first support member 1 docks with the battery pack and supports the battery pack. During the docking process between the battery pack and the first support member 1, the battery pack applies pressure to the first support member 1. The pressure on the first support member 1 is transmitted to the second support member 2 through the first connector 3, and then to the floating adjustment component 4 through the second support member 2. The second support member 2 compresses the floating adjustment component 4, causing the floating adjustment component 4 to move towards the battery swapping forklift. When the battery pack is in an inclined state, the first support member 1 and the battery... During the docking process, the battery pack experiences uneven force. The first support member 1 initially contacts the lower side of the battery pack's lower surface. The lower surface of the battery pack exerts greater pressure on the floating adjustment component 4, causing the floating adjustment component 4 corresponding to the lower side to move a longer distance downward. As the battery swapping device 100 continues to move towards the battery pack, the first support member 1 is tilted under the action of the battery pack. Ultimately, during the docking process, the first support member 1 can be made parallel to the lower surface of the battery pack, ensuring that the first support member 1 is in contact with the lower surface of the battery pack. This prevents the battery pack from being suspended during the battery swapping process, thus avoiding the battery pack from falling and being damaged, and greatly improving the reliability and safety of battery pack replacement.

[0057] Therefore, by setting multiple floating adjustment components 4, it is possible to ensure that the first support 1 is in contact with the lower surface of the battery pack during the docking process between the battery pack and the first support 1, thereby preventing the battery pack from being suspended in the air during the battery replacement process, thus preventing the battery pack from falling and being damaged, and greatly improving the reliability and safety of battery pack replacement.

[0058] According to one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 6As shown, it also includes: a locking component 5, which is movably disposed on the first support member 1, and the locking component 5 has a first position and a second position relative to the first support member 1. When the locking component 5 is in the first position, the locking component 5 is suitable for locking or unlocking the battery pack. The first support member 1 has a support surface 10 for supporting the battery pack. When the locking component 5 is in the second position, the locking component 5 is located on the side of the support surface 10 away from the battery pack.

[0059] Specifically, such as Figure 2 As shown, the battery swapping device 100 also includes a locking assembly 5, wherein the locking assembly 5 is movable relative to the first support member 1, so that the locking assembly 5 can move relative to the first support member 1 to a first position and a second position. Optionally, the movement mode includes, but is not limited to, translation and rotation.

[0060] As a specific example, when the battery swapping forklift drives the battery swapping device 100 to replace the battery pack, the forklift drives the battery swapping device 100 to move towards the battery pack to achieve docking between the battery pack and the first support member 1. In some embodiments of the present invention, before replacing the battery pack, the battery swapping device 100 controls the locking component 5 to be in a second position. After the battery pack docks with the first support member 1, that is, after the first support member 1 is in contact with the lower surface of the battery pack, the battery pack needs to be locked by the locking component 5. Specifically, the locking component 5 is controlled to move to the first position. It should be noted that when the locking component 5 is in the first position, part of the structure of the locking component 5 is fitted with the locking part of the battery pack, and is driven by... The locking component 5 locks the battery pack. Before the battery pack is removed from the battery swapping light truck and transferred to the battery swapping station, the locking component 5 is driven to unlock the battery pack and moved to the second position. It should be noted that when the locking component 5 is in the second position, it is located on the side of the support surface 10 away from the battery pack, that is, the locking component 5 moves to the bottom of the support surface 10. This can avoid interference between the battery pack and the locking component 5 when the battery pack is transferred to the battery swapping station, which would cause the battery pack transfer to fail. At the same time, during the battery pack replacement process, locking the battery pack with the locking component 5 can also prevent the battery pack from falling, thereby avoiding the impact during the transfer of the battery pack and improving the safety performance of the battery pack.

[0061] According to one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 6 As shown, the locking assembly 5 is movable relative to the first support member 1 along the thickness direction of the first support member 1, so that the locking assembly 5 can move to a first position or a second position.

[0062] Specifically, the locking component 5 can move relative to the first support member 1 along the thickness direction of the first support member 1. Before replacing the battery pack, the battery swapping device 100 controls the locking component 5 to be in the second position, that is, controls the locking component 5 to be below the support surface 10. After the battery pack is connected to the first support member 1, that is, after the first support member 1 is in contact with the lower surface of the battery pack, the locking component 5 is controlled to move from the second position to the first position along the thickness direction of the first support member 1, so that part of the structure of the locking component 5 can be fitted with the locking part of the battery pack. This setting can ensure that the locking component 5 moves perpendicular to the support surface 10. Since the first support member 1 is in contact with the lower surface of the battery pack, when part of the structure of the locking component 5 is fitted with the locking part of the battery pack, it ensures that the locking component 5 and the corresponding locking part of the battery pack are coaxially locked and unlocked, that is, it ensures that the locking component 5 can be directly facing the locking part of the battery pack to lock and unlock it, which is beneficial to improve the locking effect of the battery pack, further avoids the risk of the battery pack falling during the replacement process, and is beneficial to further improve the safety performance of the battery pack.

[0063] According to one embodiment of the present invention, such as Figure 2 , Figure 4 and Figure 6 As shown, the locking assembly 5 includes a locking mechanism 51 and a lifting mechanism 52. The locking mechanism 51 is fixed to the lifting mechanism 52, and the first support member 1 is provided with a first clearance hole 11 that cooperates with the locking mechanism 51. The lifting mechanism 52 is provided on the first support member 1, and the lifting mechanism 52 is movable relative to the first support member 1 along the thickness direction of the first support member 1, so that the locking mechanism 51 moves through the first clearance hole 11 to a first position or a second position.

[0064] Specifically, the locking assembly 5 includes a locking mechanism 51 and a lifting mechanism 52. The locking mechanism 51 can be configured as a locking motor, which is vertically fixed to the lifting mechanism 52. The fixed installation method includes, but is not limited to, bolt connection. The first support member 1 is provided with a first clearance hole 11, which corresponds to the corresponding locking mechanism 51, so that the locking mechanism 51 can extend or retract from the corresponding first clearance hole 11. Furthermore, the lifting mechanism 52 can move relative to the first support member 1 along the thickness direction of the first support member 1.

[0065] As a specific example, before replacing the battery pack, the battery swapping device 100 controls the locking assembly 5 to be in the second position, that is, controls the lifting mechanism 52 to move so that the locking mechanism 51 retracts into the first clearance hole 11. After the battery pack is connected to the first support member 1, that is, after the first support member 1 is in contact with the lower surface of the battery pack, the lifting mechanism 52 is driven to move upward along the thickness direction of the first support member 1 so that the locking mechanism 51 extends out of the first clearance hole 11 and into the locking part of the battery pack, so that the locking mechanism 51 moves to the first position to cooperate with the locking part of the battery pack and controls the locking mechanism 51 to lock the battery pack to achieve the fixation of the battery pack. When the battery pack is removed from the battery swapping light truck and transferred to the battery swapping station, the locking mechanism 51 is controlled to unlock the battery pack and the lifting mechanism 52 is driven to move downward along the thickness direction of the first support member 1 so that the locking mechanism 51 retracts into the first clearance hole 11 again, that is, the locking mechanism 51 moves to below the support surface 10. With this configuration, the locking mechanism 51 and the lifting mechanism 52 work together to achieve the lifting and unlocking of the battery swapping device 100. The structure is simple and reliable, which helps to improve the battery swapping efficiency of the battery swapping device 100. At the same time, since the first support member 1 is in contact with the lower surface of the battery pack, when the locking mechanism 51 is assembled with the locking part of the battery pack, the locking mechanism 51 and the locking part of the battery pack are coaxially connected, which helps to improve the locking effect of the battery pack.

[0066] It should be noted that multiple locking mechanisms 51 and lifting mechanisms 52 can be provided, and multiple locking mechanisms 51 can be provided on the same upgrade mechanism. For example, as shown in 4, two lifting mechanisms 52 are provided on both sides of the battery swapping device 100, and each lifting mechanism 52 is provided with three locking mechanisms 51. This arrangement can achieve the simultaneous up and down movement of the three locking mechanisms 51, which improves the battery swapping efficiency. Furthermore, providing multiple locking mechanisms 51 is beneficial to further improve the connection strength between the battery pack and the battery swapping device 100.

[0067] According to one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the lifting mechanism 52 includes: a lifting member 521, a first guide member 522, and a second guide member 523. A locking mechanism 51 is fixed to the lifting member 521. The first guide member 522 is fixed to the side of the lifting member 521 away from the first support member 1. The second guide member 523 is disposed on the first guide member 522 and is along the thickness direction perpendicular to the first support member 1. The second guide member 523 is movable relative to the first guide member 522. The second guide member 523 has a driving inclined surface 5231. The first support member 1 is provided with a driving wheel 12 that is fitted with the driving inclined surface 5231. Through the sliding cooperation between the driving inclined surface 5231 and the driving wheel 12, the lifting member 521 is driven to move relative to the first support member 1 along the thickness direction of the first support member 1 when the second guide member 523 moves relative to the first guide member 522.

[0068] Specifically, such as Figure 5 As shown, the lifting member 521 can be constructed as a lifting plate, the locking mechanism 51 is vertically fixedly installed on the lifting plate, the first guide member 522 is fixedly installed on the side of the lifting member 521 away from the first support member 1, that is, the first guide member 522 is fixedly installed on the lower surface of the lifting plate, and the second guide member 523 is provided on the first guide member 522. Specifically, the first guide member 522 can be constructed as a linear guide rail, which extends along the thickness direction perpendicular to the first support member 1. Further, the second guide member 523 is constructed as a slider that guides and cooperates with the linear guide rail. The slider is provided on the linear guide rail and can move along the extension direction of the linear guide rail.

[0069] Furthermore, a driving inclined surface 5231 is provided on the lower side of the slider. The extension direction of the driving inclined surface 5231 has a certain angle with the support surface 10 of the first support member 1. The first support member 1 is provided with a driving wheel 12 that is fitted and assembled with the driving inclined surface 5231. The driving wheel 12 and the driving inclined surface 5231 can slide relative to each other. With this arrangement, the linear motion of the slider relative to the linear guide rail can be converted into the relative lifting motion of the driving wheel 12 and the slider. That is, through the driving cooperation of the driving inclined surface 5231 and the driving wheel 12, the lifting member 521 can move up and down along the thickness direction of the first support member 1. Moreover, the above structure is simple and reliable, ensuring the reliability of the movement of the lifting member 521.

[0070] According to one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the lifting mechanism 52 further includes a driving member 524, which is disposed on the lifting member 521 and fixedly connected to the second guide member 523. The driving member 524 is used to drive the second guide member 523 to move relative to the first guide member 522 along a direction perpendicular to the thickness of the first support member 1. Specifically, as shown... Figure 4 As shown, the driving component 524 can be configured as a drive motor. The drive motor is fixedly mounted on the lower surface of the lifting component 521 and fixedly connected to the slider. The drive motor is used to drive the slider to move linearly relative to the linear guide rail. Specifically, refer to... Figure 5 As shown, the slider is driven by the drive motor to move relative to the linear guide rail, so that the drive inclined surface 5231 of the slider slides relative to the sliding wheel, thereby causing the slider to move up and down relative to the first support plate along the thickness direction of the first support member 1. This realizes the automatic control of the lifting movement of the lifting member 521 and improves the automation rate of the battery swapping device 100.

[0071] According to one embodiment of the present invention, the lifting mechanism 52 further includes: a third guide member 525, the third guide member 525 being fixedly disposed on the lifting member 521, and the first support member 1 being provided with a fourth guide member 13 that is fitted and assembled with the third guide member 525. The lifting mechanism 52 is moved relative to the first support member 1 along the thickness direction of the first support member 1 by the guiding cooperation of the third guide member 525 and the fourth guide member 13.

[0072] Specifically, the lifting mechanism 52 further includes a third guide member 525, which is fixed to the lifting member 521. A fourth guide member 13, which mates with the third guide member 525, is provided on the lower surface of the first support member 1. Under the guidance of the third guide member 525 and the fourth guide member 13, the lifting mechanism 52 can move relative to the first support member 1 along its thickness direction. Further, one of the third guide member 525 and the fourth guide member 13 is a guide pin, and the other is a guide sleeve. The guide pin is slidably disposed on the guide sleeve, and both the guide pin and the guide sleeve extend along the thickness direction of the first support member 1. If the third guide member 525 is a guide pin, then the fourth guide member 13 is a guide sleeve; if the third guide member 525 is a guide sleeve, then the fourth guide member 13 is a guide pin. The guide pin can slide along the guide sleeve along the thickness direction of the first support member 1.

[0073] Therefore, through the combined use of the third guide member 525 and the fourth guide member 13, the lifting mechanism 52 can be ensured to move smoothly in the thickness direction of the first support member 1, avoiding directional deviation during the movement. Moreover, the guide pin and guide sleeve have a simple structure and are easy to assemble.

[0074] According to one embodiment of the present invention, such as Figure 2 and Figure 6 As shown, the locking assembly 5 also includes: a first positioning member 53, which is fixed to the lifting mechanism 52, and the first support member 1 is provided with a second clearance hole 14, with the first positioning member 53 and the second clearance hole 14 correspondingly arranged.

[0075] Specifically, such as Figure 2 As shown, the first positioning member 53 can be constructed as a positioning pin. The first positioning member 53 is fixedly installed on the lifting mechanism 52. Specifically, each of the lifting members 521 on both sides of the battery swapping device 100 is provided with a first positioning member 53. Furthermore, the first support member 1 is provided with a second clearance hole 14. The first positioning member 53 is correspondingly arranged with the second clearance hole 14. This arrangement allows the first positioning member 53 to extend or retract from the corresponding second clearance hole 14.

[0076] As a specific example, before replacing the battery pack, when the locking assembly 5 is in the second position, the first positioning member 53 retracts into the second clearance hole 14. After the battery pack is connected to the first support member 1, that is, after the first support member 1 is in contact with the lower surface of the battery pack, the driving lifting mechanism 52 moves upward along the thickness direction of the first support member 1, so that the first positioning member 53 extends out of the second clearance hole 14 and into the positioning part of the battery pack, thereby achieving precise positioning of the battery pack and the battery swapping device. At the same time, the first positioning member 53 can also restrict the movement of the battery pack during the transfer process. When the battery pack is removed from the battery swapping light truck and transferred to the battery swapping station, the driving lifting mechanism 52 moves downward along the thickness direction of the first support member 1, so that the first positioning member 53 retracts back into the second clearance hole 14. This setting can avoid interference between the battery pack and the first positioning member 53 when the battery pack is transferred to the battery swapping station, which would cause the battery pack transfer to fail.

[0077] It should be noted that the battery swapping device 100 also has a second positioning component 7, which is fixed to the first support plate. The second positioning component 7 is used to achieve coarse positioning of the battery swapping device 100 and the battery pack. With this configuration, the positioning accuracy of the battery swapping device 100 and the battery pack is further improved through the cooperation of the first positioning component 53 and the second positioning component 7.

[0078] According to one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the floating adjustment assembly 4 includes a second connector 41, a third connector 42, and an elastic member 43. The second connector 41 is fixedly connected to the second support member 2. The third connector 42 is adapted to be fixedly connected to the battery swapping forklift. The second connector 41 and the third connector 42 are opposite to each other and spaced apart. The elastic member 43 is located between the second connector 41 and the third connector 42 and moves along the lifting direction of the battery swapping device 100. The second connector 41 is adapted to move toward or away from the third connector 42.

[0079] Specifically, such as Figure 3 As shown, both the second connecting member 41 and the third connecting member 42 can be constructed as connecting plates, and the elastic member 43 can be constructed as a spring. The second connecting member 41 and the third connecting member 42 are fixedly connected to the second support member 2 and the forks 202 of the electric forklift, respectively. The elastic member 43 is connected between the second connecting member 41 and the third connecting member 42. With this configuration, when the elastic member 43 is under pressure, the second connecting member 41 moves toward the third connecting member 42. When the elastic member 43 is released from pressure, the second connecting member 41 moves away from the third connecting member 42. Since both the second connecting member 41 and the third connecting member 42 are plate-shaped structures, the contact area between the elastic member 43 and the second connecting member 41 and the third connecting member 42 is increased, which is beneficial to improving the stability of the relative displacement of the second connecting member 41 and the third connecting member 42.

[0080] As a specific example, when the battery swapping forklift drives the battery swapping device 100 to replace the battery pack, the forklift drives the battery swapping device 100 to move towards the battery pack so that the battery pack docks with the first support member 1. During the docking process, the battery pack applies pressure to the first support member 1, so as to drive the second support member 2 to compress the elastic member 43 through the first connector 3, so that the second connector 41 moves towards the third connector 42. In this way, the distance between the first support member 1 and the fork 202 is adjusted. Furthermore, the attitude adjustment of the battery swapping device 100 is achieved by the coordinated use of multiple floating adjustment components 4, so that the first support member 1 is parallel to the lower surface of the battery pack, which facilitates the contact between the first support member 1 and the lower surface of the battery pack and is conducive to the smooth replacement of the battery pack.

[0081] According to one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the floating adjustment assembly 4 also includes a guide structure 44, which is connected between the second connector 41 and the third connector 42. The guide structure 44 is adapted to guide the second connector 41 to move along the lifting direction of the battery swapping device 100.

[0082] Specifically, the guide structure 44 includes a first guide portion 441 and a second guide portion 442. The first guide portion 441 is fixedly connected to the second connecting member 41, and the second guide portion 442 is fixedly connected to the third connecting member 42. Optionally, the first guide portion 441 can be constructed as a cylinder, and the second guide portion 442 can be constructed as a sleeve. The cylinder can be installed inside the sleeve, and the cylinder can move up and down relative to the sleeve along the lifting direction of the battery swapping device 100. Further, the elastic member 43 can be arranged around the guide structure 44. Specifically, it is located between the battery pack and the first support member 1. During the docking process, the first connector 3 drives the second support 2 to compress the elastic member 43. During this process, the second connector 41 drives the first guide part 441 to move relative to the second guide part 442, so that the second connector 41 moves toward the third connector 42. This arrangement realizes the guiding cooperation between the second guide part 442 and the first guide part 441, avoids the second connector 41 from deviating when it moves toward the third connector 42, improves the stability of the first support 1 during the downward movement, and helps to improve the adhesion between the first support 1 and the lower surface of the battery pack.

[0083] It should be noted that, as Figure 6 and Figure 7As shown, the battery swapping device 100 further includes a rolling element 6, which is rotatably disposed on the first support member 1 and is adapted to abut against the battery pack. Specifically, the battery swapping device 100 further includes multiple rolling elements 6, each of which is disposed on a corresponding third clearance hole 15 on the first support member 1, ensuring that a portion of the rolling element 6 extends out of the third clearance hole 15. Optionally, the rolling element 6 can be configured as a bullseye bearing. The battery pack can be mounted on the rolling element 6 through abutment and assembly. This configuration facilitates the removal of the battery pack from the first support member 1 and its placement into the battery swapping compartment of the corresponding battery swapping station, thereby greatly improving the battery pack replacement efficiency.

[0084] like Figure 1 As shown, the battery-swapping forklift 200 according to a second aspect embodiment of the present invention includes: a forklift body 201 and a battery-swapping device 100. The forklift body 201 has forks 202. The battery-swapping device 100 is the same as the battery-swapping device 100 in the first aspect embodiment. The battery-swapping device 100 is fixed to the forks 202 of the battery-swapping forklift 200. The forks 202 are used to drive the battery-swapping device 100 to lift and lower.

[0085] Specifically, the battery-swapping forklift 200 has a battery-swapping device 100. The battery-swapping forklift 200 replaces the battery pack at the bottom of the battery-swapping truck by driving the lifting and lowering of the battery-swapping device 100, greatly improving the battery pack replacement efficiency. Figure 1 As shown, in some embodiments of the present invention, the forklift body 201 of the battery swapping forklift 200 has forks 202, and the battery swapping device 100 is fixedly installed on the forks 202. The installation method includes, but is not limited to, bolt connection. With this configuration, the battery swapping device 100 can be docked with the battery pack at the bottom of the battery swapping truck by driving the lifting and lowering of the forks 202 of the battery swapping forklift 200, which facilitates the replacement of the battery pack and improves the replacement efficiency of the battery pack.

[0086] According to the embodiment of the present invention, the battery swapping forklift 200, by providing the above-mentioned battery swapping device 100 and by setting multiple floating adjustment components 4, can ensure that the first support member 1 is in contact with the lower surface of the battery pack during the docking process between the battery pack and the first support member 1, thereby preventing the battery pack from being suspended in the air during the battery swapping process, thus preventing the battery pack from falling and being damaged, and greatly improving the reliability and safety of battery pack replacement.

[0087] According to a third aspect of the present invention, the battery swapping station includes the battery swapping forklift 200 of the second aspect embodiment.

[0088] According to an embodiment of the present invention, the battery swapping station, by providing the aforementioned battery swapping forklift 200, greatly improves the reliability and safety of battery pack replacement.
