[0078] Please refer to Figure 1 and Figure 2 The battery lifting appliance 100 comprises a base frame 110, at least one hook assembly 120, and at least one driving member 130. The hook assembly 120 is arranged on the base frame 110. The hook assembly 120 comprises a hook 121, which is pivotable about a first axis extending in a vertical direction DH between a hoisting position and a release position. The driving member 130 is arranged on the base frame 110, and is configured to drive the hook 121 to pivot. The driving member 130 comprises an execution portion 131, which is movable along a first horizontal direction D1 between a first position and a second position. It is to be noted that when the execution portion 131 is located at the first position, the hook 121 is located at the hoisting position; and when the execution portion 131 is located at the second position, the hook 121 is located at the release position. Further, the battery lifting appliance 100 further comprises a transmission mechanism 140. The transmission mechanism 140 is connected between the execution portion 131 and the hook 121, so as to enable the execution portion 131 to drive the hook 121 to pivot. Specifically, please refer to Figure 3The transmission mechanism 140 comprises a first guide rail 141 and a first sliding block 142. The first guide rail 141 extends along a second horizontal direction D2, and the first sliding block 142 is slidably connected to the first guide rail 141. One of the first guide rail 141 and the first sliding block 142 is used to move along the first horizontal direction D1 under the driving of the execution part 131, and the other of the first guide rail 141 and the first sliding block 142 is connected with the hook 121 to drive the hook 121 to pivot. The second horizontal direction D2 intersects the first horizontal direction D1.

[0079] According to the battery lifting appliance 100 of the present scheme, the combination of the first guide rail 141 and the first sliding block 142 is adopted to replace the existing sliding groove and roller, which not only can improve the pivoting accuracy of the hook 121, but also can solve the alarm problem and safety hazard of the battery lifting appliance 100 due to the pivoting angle error of the hook 121, and can prolong the service life of the battery lifting appliance 100.

[0080] Please continue to refer to Figure 3 Further, the transmission mechanism 140 further comprises a first transmission member 143 and a second transmission member 144. Specifically, the first transmission member 143 is connected to the execution part 131 and moves with the execution part 131. One of the first guide rail 141 and the first sliding block 142 is fixedly connected to the first transmission member 143. One end of the second transmission member 144 is connected to the hook 121 and pivots synchronously with the hook 121, and the other end of the second transmission member 144 away from the hook 121 is rotatably connected to the other of the first guide rail 141 and the first sliding block 142 about a second axis extending along a vertical direction DH. Preferably, in the present embodiment, the first guide rail 141 is connected to the first transmission member 143, and the first sliding block 142 is connected to the second transmission member 144. The first sliding block 142 is connected to the second transmission member 144 by a pin shaft, for example; correspondingly, the axis of the pin shaft is the aforementioned second axis.

[0081] It can be understood that, in order to make the movement of the first transmission member 143 relative to the base frame 110 more accurate and smooth, the battery lifting appliance 100 further comprises a guide assembly 150. Specifically, please refer to Figures 1 to 3 The base frame 110 is provided with a mounting seat 133, and the driving member 130 is connected to the mounting seat 133. The guide assembly 150 is arranged between the first transmission member 143 and the base frame 110 to guide the first transmission member 143 to move along the first horizontal direction D1 relative to the base frame 110. Figure 3In the embodiment, the guide assembly 150 is arranged between the mounting base 133 and the first transmission member 143. The guide assembly 150 comprises a second guide rail 151 and a second sliding block 152. The second guide rail 151 extends along the first horizontal direction D1, and the second sliding block 152 is slidably connected to the second guide rail 151. Preferably, the second guide rail 151 is fixedly connected to the mounting base 133, and the second sliding block 152 is connected to the first transmission member 143 at an end thereof away from the second guide rail 151. Moreover, the guide assembly 150 is arranged in pairs, and the two guide assemblies 150 arranged in pairs are spaced apart along the second horizontal direction D2. When the execution part 131 moves along the first horizontal direction D1 between the first position and the second position, the first transmission member 143 moves along the first horizontal direction D1 following the execution part 131, so that the second sliding block 152 connected to the first transmission member 143 moves along the first horizontal direction D1 relative to the second guide rail 151, so as to make the movement of the first transmission member 143 more accurate and smooth.

[0082] Referring back to Figures 3 to 6 The hook 121 comprises a hook portion 125 and a pivot shaft 123. Specifically, the pivot shaft 123 extends along the vertical direction DH, and the pivot shaft 123 is pivotable about a first axis. It can be understood that the first axis is the axis of the pivot shaft 123 itself. The hook portion 125 is arranged at an end of the pivot shaft 123 away from the transmission mechanism 140, and the hook portion 125 extends along the horizontal direction or substantially along the horizontal direction. This is because the hook portion 125 has a load-bearing surface for supporting (or hoisting) the battery, and depending on different types of batteries, the load-bearing surface of the hook portion 125 can be arranged horizontally or at a certain inclination angle relative to the horizontal direction to match the specific battery type. Preferably, the hook portion 125 extends along the horizontal direction. The second transmission member 144 is sleeved on the outer circumferential side of the pivot shaft 123 at an end thereof away from the hook portion 125. Further, the hook assembly 120 further comprises a shaft sleeve 122 and a bearing 124. Specifically, the shaft sleeve 122 is arranged on the base frame 110, and the shaft sleeve 122 is located on the outer periphery of the pivot shaft 123. The bearing 124 is sleeved between the pivot shaft 123 and the shaft sleeve 122, so that the pivot shaft 123 rotates relative to the shaft sleeve 122.

[0083] Referring back to Figure 3Further, the driving member 130 further comprises a body portion 132, which is arranged on the base frame 110; specifically, is arranged on the mounting seat 133. It can be understood that the driving member 130 can be configured as one of a pneumatic cylinder, an electric cylinder, an oil cylinder and the like telescopic cylinder structure. It should be noted that when the executing portion 131 is located at the first position, the executing portion 131 is in one of the states of extending and retracting relative to the body portion 132 along the first horizontal direction D1; when the executing portion 131 is located at the second position, the executing portion 131 is in the other state of extending and retracting relative to the body portion 132 along the first horizontal direction D1. Preferably, when the executing portion 131 is located at the first position, the executing portion 131 is in the state of extending relative to the body portion 132 along the first horizontal direction D1; correspondingly, when the executing portion 131 is located at the second position, the executing portion 131 is in the state of retracting relative to the body portion 132 along the first horizontal direction D1. That is, when the executing portion 131 is in the state of extending relative to the body portion 132 along the first horizontal direction D1, the hook 121 is located at the hoisting position; when the executing portion 131 is in the state of retracting relative to the body portion 132 along the first horizontal direction D1, the hook 121 is located at the releasing position.

[0084] Please continue to refer to Figure 3 When the hook 121 is located at the releasing position, a single hook 121 is not easy to carry and hoist multiple batteries; therefore, preferably, the battery lifting appliance 100 comprises a plurality of hook assemblies 120, the hook assemblies 120 are arranged in pairs, the two hook assemblies 120 arranged in pairs are spaced apart along the second horizontal direction D2 and connected to the same driving member 130, and the pivoting directions of the two hook assemblies 120 arranged in pairs are opposite. Correspondingly, the second transmission members 144 are arranged in pairs, the two hook assemblies 120 arranged in pairs are respectively located on both sides of the first transmission member 143 along the second horizontal direction D2; specifically, one end of any second transmission member 144 is connected to one hook 121 and pivots synchronously with the hook 121, and the other end of the second transmission member 144 away from the hook 121 is rotatably connected to the first sliding block 142 about the second axis extending along the vertical direction DH. It can be understood that for a battery with a larger size, a single hook 121 is also not easy to carry and hoist the battery with a larger size, and preferably, the number of hook assemblies 120 is multiple pairs, and each pair of hook assemblies 120 is spaced apart from other pairs of hook assemblies 120 along the first horizontal direction D1. It is easily conceivable that the plurality of hook assemblies 120 arranged along the first horizontal direction D1 can cooperate with each other to carry and hoist the same battery with a larger size.

[0085] Preferably, the first guide rail 141 is configured to move along the first horizontal direction D1 under the drive of the execution part 131, and the first sliding block 142 is connected with the hook 121 to drive the hook 121 to pivot. It can be understood that the second horizontal direction D2 is perpendicular or inclined to the first horizontal direction D1; preferably, the second horizontal direction D2 is perpendicular to the first horizontal direction D1. Moreover, the first horizontal direction D1 is preferably configured as the length direction of the base frame 110, and the second horizontal direction D2 is preferably configured as the width direction of the base frame 110. The included angle between the hook 121 in the lifting position and the release position is substantially 90°, for example, 90°±2°, and preferably, the included angle between the hook 121 in the lifting position and the release position is 90°.

[0086] In order to ensure that the execution part 131 moves between the first position and the second position, and avoid the transmission error caused by the position overshoot of the execution part 131, the battery lifting appliance 100 further comprises a detection assembly 160. Specifically, the detection assembly 160 comprises a first detection member 161 and a second detection member 162 connected to the base frame 110. It should be noted that when the execution part 131 is located at the first position, the transmission mechanism 140 triggers or abuts against the first detection member 161; when the execution part 131 is located at the second position, the transmission mechanism 140 triggers or abuts against the second detection member 162. It can be understood that the first detection member 161 can be configured as a sensor or a pure mechanical limit structure; correspondingly, the second detection member 162 can also be configured as a sensor or a pure mechanical limit structure to limit the operation of the drive member 130.

[0087] The working principle of the battery lifting appliance 100 is briefly described as follows.

[0088] Figure 3 and Figure 6In the middle, the execution part 131 is in the state of retracting along the first horizontal direction D1 relative to the main body part 132, that is, the execution part 131 is located at the second position, the hook 121 is located at the release position, and the transmission mechanism 140 triggers the second detection member 162. Start the drive member 130 to operate, so that the execution part 131 extends along the first horizontal direction D1 relative to the main body part 132, that is, the execution part 131 moves from the second position to the first position. In the process of moving the execution part 131 from the second position to the first position, the first transmission part 143 moves along with the execution part 131 along the first horizontal direction D1 from the position close to the second detection member 162 to the position close to the first detection member 161. The second sliding block 152 moves along the first horizontal direction D1 relative to the second guide rail 151 to improve the accuracy and stability of the movement of the first transmission part 143. The first sliding block 142 moves along the second horizontal direction D2 on the first guide rail 141 towards the middle part of the first transmission part 143, that is, the two first sliding blocks 142 adjacent along the second horizontal direction D2 are close to each other, and at the same time, the second transmission part 144 connected with the first sliding block 142 is pivoted around the second axis, so as to drive the hook part 125 of the hook 121 to pivot around the first axis to the hoisting position (see Figure 7 ) through the rotating shaft 123.

[0089] The utility model also provides a battery swap station, the battery swap station includes battery and preceding battery lifting appliance 100, and the battery lifting appliance 100 is used for hoisting battery. It can be understood that the battery lifting appliance 100 hoists battery in the case where the hook 121 is located at the hoisting position, and the battery lifting appliance 100 is separated from the battery in the case where the hook 121 is located at the release position.

[0090] The process of hoisting battery by the battery lifting appliance 100 is briefly described below.

[0091] The hoisted battery is usually a box structure, and the outside of the box is provided with lifting lugs or buckles for hoisting. Before the battery lifting appliance 100 hoists the battery, the battery lifting appliance 100 is controlled by the relevant control system (such as a vision system or a sensor) in the battery swap station to position the lifting lug or buckle position of the battery. The hook 121 is pivoted from the release position to the hoisting position under the drive of the drive member 130 and accurately docks with the lifting lug or buckle of the battery, and then the battery is locked with the hook 121. It can be understood that different specifications of battery lifting appliances 100 can be selected for different sizes and types of batteries. For example, a single hook 121 is connected to a single battery, or a plurality of hooks 121 distributed at intervals along the first horizontal direction D1 are used to connect to the lifting lugs or buckles of the same battery. The battery lifting appliance 100 lifts and moves the battery to the target position by a lifting device (such as a winch or a hydraulic arm). After reaching the target position, the battery is unlocked from the hook 121 and released smoothly. Then the hook 121 is pivoted from the hoisting position to the release position under the drive of the drive member 130.

[0092] The battery lifting appliance can improve the running precision of the transmission mechanism, thereby ensuring the pivoting precision of the hook, effectively reducing the alarm of the battery swap station system, reducing the safety hazard, and prolonging the service life of the battery lifting appliance.
