[0047] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments of the present application will be described in more detail below in combination with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference signs represent the same or similar components or components with the same or similar functions throughout. The described embodiments are part of the embodiments of the present application, not all the embodiments. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below in combination with the drawings.

[0048] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms “mounting”, “connection” and “connection” should be understood in a broad sense, for example, it can be fixed connection, or indirect connection through an intermediate medium, or internal communication of two elements or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] In the description of the present application, it needs to be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0050] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0051] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or displays.

[0052] In the prior art, the battery lifting appliance includes a frame, a guide block, a lifting hook, a transmission assembly and a driving member, the guide block is fixedly installed at the bottom of the frame, the lifting hook is arranged below the frame, the driving member is connected with the lifting hook through the transmission assembly, and the driving member can drive the lifting hook to rotate relative to the frame within a certain range during work. During use of the battery lifting appliance, the travelling crane of the battery swap station is connected with the frame of the battery lifting appliance, positioning between the battery lifting appliance and the battery pack to be hoisted can be realized through the guide block, and the battery pack can be hooked through rotation of the lifting hook to realize hoisting of the battery pack. A kind of existing battery lifting appliance uses electric push rod as driving member, uses guide rail connecting rod mechanism or gear and rack mechanism as transmission assembly, electric push rod indirectly drives lifting hook to rotate through transmission assembly, transmission efficiency is low, failure rate is high and lifting hook can only rotate within a certain range. And the position of the guide block cannot be adjusted, and the guide block can only be positioned with battery packs of a specific specification. The above reasons make the battery lifting appliance less versatile, different battery lifting appliances are needed for battery packs of different specifications, and hoisting and replacement of battery packs are relatively inconvenient.

[0053] After repeated thinking and verification, the inventor found that if the lifting hook is directly driven to rotate by the transmission shaft through the rotary driving member, the transmission structure between the lifting hook and the driving member can be simplified, the lifting hook is less likely to fail during rotation, and the lifting hook can rotate 360°. A plurality of mounting positions are provided in the area of the frame of the battery lifting appliance for mounting the guide block, and the guide block can be mounted on the appropriate mounting position as needed, i.e. the position of the guide block can be adjusted as needed. In this way, the battery lifting appliance is more versatile and can be applied to more specifications of battery packs.

[0054] Therefore, the inventors design a battery lifting appliance and a battery swap station. The rotating driving member directly drives the lifting hook to rotate through the transmission shaft. The lifting hook can rotate by 360°. The battery lifting appliance has good compatibility, high speed, high efficiency and high reliability. Multiple mounting positions are arranged at the position where the battery lifting appliance is used to install the guide block. The guide block can be installed on the appropriate mounting position according to the specification of the battery pack to be hoisted. The guide block position can be adjusted by installing the guide block on different mounting positions, thereby further improving the compatibility and universality of the battery.

[0055] The technical solutions of the battery lifting appliance and the battery swap station provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0056] Referring to Figures 1 to 3 The battery lifting appliance provided by the embodiments of the present application includes a frame 100, a transmission shaft 200, a lifting hook 300, a rotating driving member 400 and at least two first guide blocks 510. At least two mounting portions 110 are arranged at intervals on the frame 100, and the mounting portion 110 is provided with at least two first mounting positions 111. The frame 100 is formed in an approximate sheet structure, and the mounting portion 110 can protrude from the main body portion of the frame 100. The number of first mounting positions 111 on the mounting portion 110 is non-limiting, for example, two, three or four first mounting positions 111 can be arranged on the mounting portion 110. The arrangement of the at least two first mounting positions 111 on the mounting portion 110 can be set according to the specification of the battery pack, which is not uniquely limited here.

[0057] As Figure 2 indicated, a down-to-position detection sensor 930 can be arranged on the frame 100. During use of the battery lifting appliance, the down-to-position detection sensor 930 can be used to obtain whether the battery lifting appliance is lowered to position.

[0058] The transmission shaft 200 penetrates the frame 100 and is rotatably connected with the frame 100. For example, the transmission shaft 200 can be rotatably connected with the frame 100 through a rotating bearing. A through hole can be arranged on the frame 100, the outer ring of the rotating bearing is embedded in the through hole, and the transmission shaft 200 penetrates the inner ring of the rotating bearing and is fixed with the inner ring. Illustratively, the axis of the transmission shaft 200 can extend in the vertical direction.

[0059] The lifting hook 300 is located below the frame 100, and the lifting hook 300 is fixedly connected with one end of the transmission shaft 200. Specifically, the lifting hook 300 is fixedly connected with the bottom end of the transmission shaft 200. The lifting hook 300 can be fixed with the bottom end of the transmission shaft 200 by welding or fastening, etc.

[0060] The rotary driving member 400 is connected to the other end of the transmission shaft 200. Illustratively, the body of the rotary driving member 400 can be mounted on the top of the frame 100 through a mounting seat 940, and the output shaft of the rotary driving member 400 is connected to the top end of the transmission shaft 200. The rotary driving member 400 can be an electric motor, a hydraulic motor, or a pneumatic motor, etc. When the rotary driving member 400 drives the transmission shaft 200 to rotate, the hook 300 can be driven to rotate synchronously with the transmission shaft 200. It can be understood that the rotary driving member 400 can drive the hook 300 to rotate 360° through the transmission shaft 200. Moreover, the transmission structure between the rotary driving member 400 and the hook 300 is simple, and the transmission efficiency and reliability are higher.

[0061] As shown in Figure 1 and Figure 2 The number of hooks 300 can be multiple, and each hook 300 can be driven to rotate by a rotary driving member 400 through a transmission shaft 200.

[0062] The first guide block 510 can be detachably mounted on different first mounting positions 111 of the mounting portion 110 to adjust the interval between adjacent two first guide blocks 510.

[0063] Specifically, the first guide block 510 is mounted on the bottom of the frame 100. The worker installs the first guide block 510 on the appropriate first mounting position 111 of the mounting portion 110 according to the specification of the battery pack to be hoisted, so that the interval between adjacent two first guide blocks 510 matches the positioning structure on the battery pack to be hoisted. At least two first guide blocks 510 can be positioned with the battery pack to be hoisted respectively to limit the movement of the battery hoist relative to the battery pack to be hoisted. Optionally, multiple first guide blocks 510 can be mounted on the same mounting portion 110, or different first guide blocks 510 can be mounted on different mounting portions 110, which is not limited herein.

[0064] In a possible implementation, the side surface of the first guide block 510 in the direction of the X-axis and the side surface in the direction of the Y-axis are respectively formed with guide surfaces, so that the first guide block 510 cooperates with the positioning structure on the battery pack.

[0065] In a possible implementation, the first guide block 510 can be fixed to the frame 100 by fastening, and the first mounting position 111 is a plurality of fastening holes on the mounting portion 110 for the fastening members to extend into. The first guide block 510 mounted on different first mounting positions 111 can be mounted on different positions of the frame 100.

[0066] The battery lifting appliance provided by the embodiment comprises a frame 100, a transmission shaft 200, a lifting hook 300, a rotating driving part 400 and at least two first guide blocks 510. The transmission shaft 200 passes through the frame 100 and can rotate relative to the frame 100. The lifting hook 300 and the rotating driving part 400 are connected with two ends of the transmission shaft 200 respectively. The rotating range of the lifting hook 300 is not limited, and the rotating driving part 400 can drive the lifting hook 300 to rotate by 360° through the transmission shaft 200. The first guide blocks 510 can be detachably installed on different first installation positions 111 of the installation part 110 to adjust the interval size between adjacent two first guide blocks 510. The workers can install the first guide blocks 510 on the suitable first installation positions 111 of the installation part 110 according to the specifications of the battery packs to be hoisted, that is, the first guide blocks 510 can be installed at different positions on the frame 100 according to the specifications of the battery packs to be hoisted, so as to adjust the interval size between the connected two first guide blocks 510, so that the at least two first guide blocks 510 can be positioned with the battery packs to be hoisted respectively. In this way, the battery lifting appliance can be suitable for battery packs of different specifications, and the versatility of the battery lifting appliance is improved.

[0067] In one embodiment, as shown in Figure 1 and Figures 3 to 5 The transmission shaft 200 is fixedly installed with a sensing part 600.

[0068] In the first direction, a first sensor 710 is installed on the frame 100 and faces the transmission shaft 200. In the second direction, a second sensor 720 is installed on the frame 100 and faces the transmission shaft 200. Here, the first direction is defined as the direction indicated by the X-axis in Figure 1 , and the second direction is defined as the direction indicated by the Y-axis in Figure 1 . The first direction and the second direction are perpendicular to each other. The first sensor 710 and the second sensor 720 can be photoelectric sensors, laser displacement sensors or proximity sensors, etc., which are not limited here. The first sensor 710 and the second sensor 720 can be respectively installed on the top surface of the frame 100 through brackets.

[0069] The first sensor 710 and the second sensor 720 are both configured to obtain the position of the sensing part 600 when facing the sensing part 600. When the transmission shaft 200 is rotated to face the first sensor 710, the first sensor 710 can obtain the position of the sensing part 600. When the transmission shaft 200 is rotated to face the second sensor 720, the second sensor 720 can obtain the position of the sensing part 600.

[0070] Illustratively, when the inductor 600 on the transmission shaft 200 is opposite one of the first sensor 710 and the second sensor 720, the hook 300 is located below the beam on the battery pack to be hoisted to realize hoisting of the battery pack; when the inductor 600 on the transmission shaft 200 is opposite the other of the first sensor 710 and the second sensor 720, the hook 300 can be separated from the beam on the battery pack to be hoisted. The rotation of the hook 300 to the in-place angle can be detected through the first sensor 710 and the second sensor 720.

[0071] Through the above setting, the worker can accurately obtain the position of the hook 300 to accurately realize hoisting and unloading of the battery pack. The power selection of the hook 300 adopts independent driving of the rotary driving part 400, which can realize real-time detection of different working states of the hook 300, and has simple structure, faster speed, higher efficiency and higher reliability.

[0072] In a specific embodiment, as shown in Figures 3 to 5 The transmission shaft 200 is formed with a shaft shoulder 210. The shaft shoulder 210 is a step portion formed on the transmission shaft 200.

[0073] The inductor 600 includes a connecting portion 610 and an inductive portion 620. The connecting portion 610 is sleeved on the transmission shaft 200, the connecting portion 610 is locked with the shaft shoulder 210 through a fastener, and the connecting portion 610 is provided with a mounting hole 611 through which the fastener passes. The connecting portion 610 is a sheet structure, and the connecting portion 610 is provided with a through hole through which the transmission shaft 200 passes. After the transmission shaft 200 passes through the through hole on the connecting portion 610, the shaft shoulder 210 thereof can abut against the connecting portion 610. The inductive portion 620 can be a strip structure, and one end thereof can be fixed with the connecting portion 610 by an integral molding manner. In a possible implementation manner, the shaft shoulder 210 of the transmission shaft 200 is provided with a plurality of fastening holes, and the fastener is locked in one of the fastening holes after passing through the mounting hole 611. In another possible implementation manner, the connecting portion 610 is provided with a plurality of mounting holes 611, and the fastener is locked on the shaft shoulder 210 of the transmission shaft 200 after passing through one of the mounting holes 611. The fastener between the connecting portion 610 and the shaft shoulder 210 passes through a specific fastening hole and the mounting hole 611 or the fastener between the connecting portion 610 and the shaft shoulder 210 passes through the fastening hole and a specific mounting hole 611 to set the included angle between the inductive portion 620 and the hook 300.

[0074] The first sensor 710 and the second sensor 720 are both configured to acquire the position of the sensing portion 620 when the sensing portion 620 is directly opposite the sensing portion 620. Specifically, when the sensing portion 620 rotates with the transmission shaft 200 to be directly opposite the first sensor 710 away from one end of the connecting portion 610, the first sensor 710 can acquire the position of the sensing portion 620; when the sensing portion 620 rotates with the transmission shaft 200 to be directly opposite the second sensor 720 away from one end of the connecting portion 610, the second sensor 720 can acquire the position of the sensing portion 620.

[0075] In the embodiment, the reliability of the connection between the sensing member 600 and the transmission shaft 200 can be ensured, and the angle between the sensing portion 620 and the hook 300 can be adjusted, further improving the versatility of the battery lifting device. In actual use, the battery lifting device can adjust the initial positions of the hook 300 and the sensing member 600 according to the battery pack hoisting structure, and then adjust the rotation working angle range of the hook 300, so as to better adapt to the hoisting and taking of various battery packs.

[0076] In other embodiments, the sensing member 600 can be a strip-shaped structure fixedly installed on the transmission shaft 200, and the angle of the hook 300 can be acquired through the cooperation between the sensing member 600 and the first sensor 710 and the second sensor 720.

[0077] In a more specific embodiment, as shown in Figures 3 to 5 The mounting hole 611 is formed in an arc shape, and the mounting hole 611 is arranged around the axis of the transmission shaft 200.

[0078] The central angle of the arc-shaped mounting hole 611 can be set as needed, and is not limited herein. The number of mounting holes 611 can be one or multiple. When the number of mounting holes 611 is multiple, the multiple mounting holes 611 are arranged around the axis of the transmission shaft 200.

[0079] It can be understood that when it is necessary to adjust the position of the sensing portion 620 relative to the hook 300, the fastener passing through the mounting hole 611 is only loosened, the connecting portion 610 is rotated to move the fastener in the mounting hole 611, and when the included angle between the sensing portion 620 and the hook 300 reaches a preset angle, the fastener is locked to complete the adjustment of the position of the sensing portion 620. The above setting facilitates the adjustment of the position of the sensing portion 620 relative to the hook 300, and the position adjustment of the sensing portion 620 is more flexible. When the number of mounting holes 611 is multiple and the multiple mounting holes 611 are arranged around the axis of the transmission shaft 200, the included angle between the sensing portion 620 and the hook 300 can be adjusted by approximately 360°.

[0080] In a specific embodiment, as shown in Figure 1As shown, the battery lifting appliance further comprises a driver 810 and an IO module 820 respectively mounted on the frame 100, and the rotating driving member 400, the first sensor 710, the second sensor 720 and the IO module 820 are respectively electrically connected with the driver 810.

[0081] In the embodiment, motors can be used as the rotating driving members 400, and the number of the rotating driving members 400 is the same as that of the drivers 810, and each rotating driving member 400 is electrically connected with a corresponding driver 810. The driver 810 and the IO module 820 can be respectively mounted on the top surface of the frame 100. It can be understood by those skilled in the art that remote adjustment of the battery lifting appliance can be realized through the IO module 820. When the IO module 820 receives a remote signal, the signal can be transmitted to the driver 810, and the driver 810 controls the rotating driving member 400 to work to realize the rotation of the lifting hook 300. When the first sensor 710 or the second sensor 720 is directly opposite the sensing portion 620, the first sensor 710 or the second sensor 720 can transmit a signal to the driver 810, and at this time the driver 810 can control the rotating driving member 400 to stop working to realize the fixation of the angle of the lifting hook 300. The specific structure of the driver 810 and the IO module 820 is not limited in the embodiment, and those skilled in the art can select appropriate drivers 810 and IO modules 820 according to needs.

[0082] In one embodiment, as shown in Figure 2 The bottom surface of the frame 100 is further provided with two oppositely arranged second guide blocks 520.

[0083] Each second guide block 520 can be mounted on the frame 100 by fastening. For example, the two second guide blocks 520 are arranged along the first direction, i.e., the direction indicated by the X axis. The guide surface of the second guide block 520 is inclined to the height direction of the second guide block 520. The battery lifting appliance can be positioned with the battery pack along the direction indicated by the X axis in Figure 1 and Figure 2 In other embodiments, the two second guide blocks 520 can also be arranged along the second direction, i.e., the direction indicated by the Y axis. The battery lifting appliance can be positioned with the battery pack along the direction indicated by the Y axis in Figure 1 and Figure 2 Optionally, the opposite sides of the two second guide blocks 520 are respectively provided with guide surfaces, so that the second guide blocks 520 cooperate with the positioning structure on the battery pack.

[0084] In the embodiment, along the arrangement direction of the two second guide blocks 520, when the first guide block 510 cannot be positioned with the battery pack, the second guide block 520 can be positioned with the battery pack, further improving the versatility of the battery lifting appliance.

[0085] In a possible implementation, as shown in Figure 2 , the frame 100 is provided with a plurality of second mounting positions 120, and two second guide blocks 520 are respectively mounted on two second mounting positions 120.

[0086] When the second guide block 520 is mounted on the frame 100 by means of fastening, the second mounting position 120 can be a fastening hole on the frame 100 for the fastener to extend into. The number of second mounting positions 120 is non-limiting, and a person skilled in the art can set it according to the needs. The worker can mount the second guide block 520 on the appropriate second mounting position 120 of the frame 100 to adjust the position of the second guide block 520 according to the needs.

[0087] It can be understood that by adjusting the position of the second guide block 520, the battery lifting appliance can be positioned between more specifications of battery packs, further improving the versatility of the battery lifting appliance.

[0088] In an embodiment, as shown in Figure 1 and Figure 2 , the frame 100 has four mounting portions 110, and the four mounting portions 110 are respectively located at the four corners of the frame 100. Each mounting portion 110 is provided with at least two first mounting positions 111.

[0089] For example, the length direction of each mounting portion 110 can extend along the direction indicated by the X axis in Figure 1 and Figure 2 , and one first guide block 510 can be respectively mounted on each mounting portion 110. Two first mounting positions 111 can be respectively arranged on each mounting portion 110, and the arrangement direction of the two first mounting positions 111 on the mounting portion 110 can be inclined to the direction indicated by the X axis in Figure 1 and Figure 2 .

[0090] In this structure, the mounting portions 110 at the four corners of the frame 100 can respectively mount the first guide blocks 510 to position the battery pack, ensuring the reliability of the positioning between the battery lifting appliance and the battery pack.

[0091] In other embodiments, the number of mounting portions 110 can be two, and the two mounting portions 110 are respectively located at the opposite corners of the frame 100.

[0092] In an embodiment, as shown in Figure 1 , at least two guide columns 130 are vertically mounted on the top surface of the frame 100.

[0093] For example, the number of guide columns 130 is two, and the two guide columns 130 extend along the direction indicated by the Y axis in Figure 1The X-axis is spaced out. Each guide post 130 can be mounted on the top surface of the frame 100 via a limiting member. The end of each guide post 130 away from the frame 100 can be tapered.

[0094] As an illustration, the overhead crane of the battery swapping station is equipped with a positioning hole into which the guide column 130 can extend. When the battery pack is hoisted, the guide column 130 can be inserted into the positioning hole. At this time, when the overhead crane moves the battery hoist, it can prevent the battery hoist from shaking and improve the stability of the battery hoist.

[0095] The following embodiments, in conjunction with the accompanying drawings, briefly describe the different working processes of the battery hoist, so that those skilled in the art can better understand the technical solutions of this application.

[0096] Example 1

[0097] like Figure 6 As shown, the lifting beam of the first battery pack 21 is the inner middle longitudinal beam. The battery lifting device is positioned in the X-direction with the inner middle longitudinal beam via the second guide block 520, and in the Y-direction with the outer crossbeam of the first battery pack 21 via the first guide block 510. The hook 300 is initially positioned symmetrically "face-to-face" in the Y-direction. The motor drives the lifting device to rotate 90° towards the inner middle longitudinal beam in the X-direction. The first sensor 710 and the second sensor 720 acquire the position of the sensing part 620 of the sensing element 600, completing the detection of the hook 300's rotation angle and realizing the lifting of the first battery pack 21.

[0098] Example 2

[0099] like Figure 7 As shown, the lifting beam of the second battery pack 22 is the outermost longitudinal beam in the middle. The battery lifting device completes the X and Y direction positioning through the first guide block 510, the outer crossbeam of the second battery pack 22, and the guide plate. The initial position of the hook 300 is adjusted to be symmetrically arranged "face to face" in the Y direction. The motor drives the lifting device to rotate 90° towards the outer longitudinal beam in the X direction. The position of the sensor 600 on the transmission shaft 200 is adjusted to complete the detection of the rotation angle of the hook 300, thus realizing the lifting of the second battery pack 22.

[0100] Example 3

[0101] like Figure 8 As shown, the lifting beam for the third battery pack 23 is the outer crossbeam. The first guide block 510 of the battery lifting device is adjusted to align with the outer crossbeam and longitudinal beam to complete the X-axis and Y-axis positioning. The initial position of the hook 300 is adjusted to a symmetrical "face-to-face" arrangement in the X-axis. The motor drives the lifting device to rotate 90° towards the outer crossbeam in the Y-axis direction. The position of the sensor 600 on the transmission shaft 200 is adjusted to complete the detection of the hook 300's rotation angle, thus achieving the lifting of the third battery pack 23.

[0102] The application also provides a battery swap station comprising the battery hoist. Illustratively, the battery swap station further comprises a trolley to drive the battery hoist to move. The trolley can be provided with a pulley, and the battery hoist can be provided with a pulley assembly 910 at the top of the frame 100. The pulley assembly 910 can form a movable pulley set with the pulley on the trolley through a steel wire, so as to realize the up-and-down lifting of the battery hoist. The battery hoist can be provided with a wire winding box 920 at the top of the frame 100, and the steel wire can be accommodated through the wire winding box 920.

[0103] The battery swap station provided by the application can be suitable for different specifications of battery packs due to the adoption of the battery hoist, and is convenient for hoisting and replacing the battery packs.
