[0067] The present application provides a battery lifting appliance.

[0068] Please refer to Figure 1The battery lifting tool 100 comprises a base frame 110, at least one hook assembly 120 and at least one driving member 130. Specifically, the hook assembly 120 is arranged on the base frame 110, and the hook assembly 120 comprises a hook 121 which is pivotable between a hoisting position and a releasing position about a first axis extending in a vertical direction DH. The driving member 130 is arranged on the base frame 110. The driving member 130 is arranged in one-to-one correspondence with the hook assembly 120. Further, the driving member 130 comprises an execution part 131 extending in a horizontal direction. The execution part 131 is movable between a first position and a second position along the extension direction of the execution part 131. The execution part 131 is connected to the hook 121 to drive the hook 121 to pivot. It should be noted that when the execution part 131 is located at the first position, the hook 121 is located at the hoisting position; and when the execution part 131 is located at the second position, the hook 121 is located at the releasing position.

[0069] According to the battery lifting tool 100 of the present scheme, the driving member 130 is arranged in one-to-one correspondence with the hook assembly 120, so that the transmission structure between the hook assembly 120 and the driving member 130 is more simple and direct, and the rotation accuracy of the hook assembly 120 is ensured.

[0070] Please refer to Figures 1 to 5 The driving member 130 further comprises a main body part 132 which is movably connected to the base frame 110. The execution part 131 is connected to the main body part 132 and is telescopic relative to the main body part 132, so that the execution part 131 is movable between the first position and the second position. Further, the execution part 131 is arranged at one end of the main body part 132 in a telescopic manner, and the other end of the main body part 132 away from the execution part 131 is pivotably connected to the base frame 110 about a third axis extending in the vertical direction DH. It can be understood that the driving member 130 can be configured as one of an electric cylinder, an oil cylinder, a gas cylinder and the like telescopic structure cylinder. Preferably, the driving member 130 is configured as an electric cylinder. The process of driving the hook assembly 120 to operate by the electric cylinder will be introduced below.

[0071] Please continue to refer to Figures 1 to 5The hook 121 includes a hook portion 125 and a pivot 123. Specifically, the pivot 123 extends vertically in the direction DH and is pivotable about its own axis. It can be understood that the axis of the pivot 123 is the aforementioned first axis. One end of the pivot 123 is connected to the actuator 131, enabling the actuator 131 to drive the pivot 123 to pivot. The hook portion 125 is located at the other end of the pivot 123 away from the actuator 131, and extends horizontally or substantially horizontally. Furthermore, the hook assembly 120 also includes a bushing 122 and a bearing 124. The bushing 122 is disposed on the base frame 110 and is located on the outer periphery of the pivot 123. The bearing 124 is sleeved between the pivot 123 and the bushing 122, allowing the pivot 123 to rotate relative to the bushing 122.

[0072] The battery lifting device 100 also includes a drive arm 144. Specifically, one end of the drive arm 144 is rotatably connected to the actuator 131 about a second axis extending in the vertical direction DH; the other end of the drive arm 144 is sleeved on the outer periphery of the end of the rotating shaft 123 away from the hook 125, so that the drive arm 144 and the rotating shaft 123 pivot synchronously. The actuator 131 is connected to the drive arm 144 by means of a pin 145; it can be understood that the axis of the pin 145 is the aforementioned second axis.

[0073] Please return to the reference section. Figures 1 to 3 To further ensure the pivoting accuracy of the hook assembly 120 and prevent the hook 121 from pivoting to positions other than the lifting and release positions, the battery lifting device 100 also includes a limiting assembly 160. Specifically, the limiting assembly 160 includes a limiting arm 163 and two positioning members 161. One end of the limiting arm 163 is sleeved on the outer periphery of the end of the rotating shaft 123 away from the hook portion 125, so that the limiting arm 163 pivots synchronously with the rotating shaft 123. Preferably, the limiting arm 163 and the aforementioned transmission arm 144 are constructed as an integral structure; in other words, the integral workpiece formed by the limiting arm 163 and the transmission arm 144 pivots along with the rotating shaft 123.

[0074] Furthermore, the two positioning elements 161 are fixed to the base frame 110 and are respectively located on the pivoting movement path of the limiting arm 163. It should be noted that when the hook 121 is in the lifting position, the limiting arm 163 is limited to one of the positioning elements 161; when the hook 121 is in the release position, the limiting arm 163 is limited to the other positioning element 161. For example, when the hook 121 is in the lifting and release positions, the limiting arm 163 abuts against both positioning elements 161 respectively. Alternatively, in Figure 1 and Figure 2In the embodiment shown, the limiting assembly 160 further includes two sensors 162, which are used to trigger the limiting arm 163 to stop rotating when the hook 121 is in the hoisting position and the release position so that the limiting arm 163 is close to the two positioning members 161 respectively, thereby stopping the drive component 130 from operating.

[0075] The following is a brief description of the operation process of the drive component 130 driving the hook assembly 120.

[0076] Figure 1 In the configuration, hook 121 is in the release position, and correspondingly, actuator 131 is in the second position, with limiting arm 163 positioned at a positioning element 161. When the drive component 130 is activated, actuator 131 extends outward relative to the main body 132. During this process, actuator 131 drives transmission arm 144 via pin 145, causing drive component 130 to pivot around a third axis. Transmission arm 144 drives rotating shaft 123 and limiting arm 163, and hook 125 pivots along with rotating shaft 123 until hook 121 pivots to the lifting position. At this point, actuator 131 reaches the first position, and limiting arm 163 pivots to be positioned at another positioning element 161. It should be noted that the angle between hook 121 in the lifting position and the release position is 90° or approximately 90°.

[0077] Please continue reading. Figure 1 and Figure 2 With the hook 121 in the released position, a single hook 121 is not suitable for supporting and hoisting multiple batteries. Therefore, preferably, the battery hoist 100 includes multiple hook assemblies 120, and correspondingly, multiple drive members 130. Specifically, the hook assemblies 120 are arranged in pairs, with the two hook assemblies 120 in a pair spaced apart along a first horizontal direction D1, and the two hook assemblies 120 in a pair having opposite pivot directions. It can be understood that for larger batteries, a single hook 121 is also not suitable for supporting and hoisting larger batteries. Preferably, the number of hook assemblies 120 is multiple pairs, with each pair of hook assemblies 120 spaced apart from the other pairs of hook assemblies 120 along a second horizontal direction D2. The second horizontal direction D2 intersects the first horizontal direction D1. It is easy to imagine that multiple hook assemblies 120 spaced apart along the first horizontal direction D2 can cooperate to support and hoist the same larger battery. Preferably, the first horizontal direction D1 is perpendicular to the second horizontal direction D2, the first horizontal direction D1 is configured as one of the length direction and the width direction of the base frame 110, and the second horizontal direction D2 is configured as the other of the length direction and the width direction of the base frame 110. For example Figure 1 In the first horizontal direction D1, the width direction of the base frame 110 is defined, and the second horizontal direction D2, the length direction of the base frame 110 is defined.

[0078] Furthermore, the battery hoist 100 also includes a control device electrically connected to all drive components 130, which controls the synchronous operation of all drive components 130. That is, the control device can control the synchronous operation of all hooks 121.

[0079] This utility model also provides a battery swapping station, which includes a battery and the aforementioned battery lifting device 100, which is used to lift the battery. It is understood that when the hook 121 is in the lifting position, the battery lifting device 100 lifts the battery; when the hook 121 is in the release position, the battery lifting device 100 separates from the battery.

[0080] The following is a brief description of the process of lifting batteries using the battery hoist 100.

[0081] The batteries being lifted are typically in a box-like structure, with lifting lugs or clips on the outside for hoisting. Before the battery lifter 100 lifts the battery, the relevant control system within the battery swapping station (such as a vision system or sensors) positions the battery lifter 100 to the lifting lugs or clips. Hook 121, driven by the drive member 130, pivots from the release position to the lifting position and precisely engages with the battery's lifting lugs or clips, then locks the battery to hook 121. It is understood that different specifications of battery lifters 100 can be selected for different battery sizes. For example, a single hook 121 connects to a single battery, or multiple hooks 121 spaced along the second horizontal direction D2 are used to connect to the same battery's lifting lugs or clips. The battery lifter 100 uses a lifting device (such as a winch or hydraulic arm) to lift and move the battery to the target position. Upon reaching the target position, the battery is released from the hook 121 and smoothly released. Then, under the drive of the drive component 130, the hook 121 pivots from the hoisting position to the release position.

[0082] According to the battery lifting device of this utility model, the driving component and the hook assembly correspond one-to-one and are uniformly controlled by the control device to ensure the pivoting accuracy of the hook. In addition, the limit component strictly restricts the pivoting of the hook between the lifting position and the release position, which is conducive to the lifting and release of the battery, reduces the number of alarms in the system, and reduces safety hazards.

[0083] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention.

A feature described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0084] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this utility model to the described embodiments. Those skilled in the art will understand that many more variations and modifications can be made based on the teachings of this utility model, and all such variations and modifications fall within the scope of protection claimed by this utility model.
