Description

Technical Field

[0001] This invention relates to the field of battery swapping, and in particular to a lifting device for battery swapping equipment. Background Technology

[0002] The installation of batteries in existing electric vehicles is generally divided into fixed and swappable types. For swappable batteries, a movable installation method is generally used, which allows the battery to be removed at any time for replacement or charging, and then installed back onto the vehicle body after replacement or charging is completed.

[0003] Existing automated battery swapping devices include a battery mounting section for installing batteries and a lifting device for raising and lowering the battery mounting section to complete battery replacement. However, existing battery swapping equipment suffers from poor control over the raising and lowering of the battery mounting section during battery replacement. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the poor lifting control effect of the battery mounting part when replacing batteries in the prior art, and to provide a lifting device for battery swapping equipment and a battery swapping equipment and a battery swapping station including the device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A lifting device for a battery swapping device is mounted on the frame of the battery swapping device, the lifting device comprising:

[0007] A drive unit is used to drive the battery mounting part of the battery swapping device to move up and down relative to the frame, and the drive unit has a preset motion path;

[0008] The detection component includes two fixed members disposed on the motion path and a follower member disposed on the drive unit. The two fixed members are disposed at intervals on the motion path, and the motion position of the drive unit is detected by sensing the follower member through the fixed members.

[0009] In this technical solution, when the follower of the detection component moves with the drive unit to a position corresponding to the fixed member, the fixed member can sense the follower. By setting the follower on the drive unit to detect the movement of the drive unit, the synchronization between the follower and the drive unit is ensured, making the movement of the drive unit detected by the drive unit detection component accurate.

[0010] The detection component can be used to detect the movement position of the drive unit and reflect the position of the battery mounting unit by detecting the position of the drive unit, thereby realizing the detection of the lifting of the battery mounting unit and controlling the movement of the drive unit according to the sensing signal of the fixing component, including controlling the drive unit to stop, so as to achieve precise control of the movement of the battery mounting unit.

[0011] In addition, the fixing members and the follower members can also serve as travel protection for the drive unit or the battery mounting unit. By setting the two fixing members at positions outside the highest and lowest positions of the corresponding battery mounting unit's movement path, and within the safe limit range of the corresponding battery mounting unit or drive unit's movement path, when the drive unit moves the battery mounting unit to the lowest or highest position and continues to move, the follower members follow the drive unit to the position corresponding to the fixing members. The fixing members can sense the follower members and control the drive unit to stop moving, thus preventing the drive unit from continuing to move to the safe limit position, or preventing the battery mounting unit from continuing to move to the safe limit position, which could cause damage to the drive unit, battery mounting unit, or other structures of the battery swapping equipment.

[0012] Preferably, the position of one of the fixing members on the movement path matches the first preset lifting position of the battery mounting part on the lifting path, and the position of the other fixing member on the movement path matches the second preset lifting position of the battery mounting part on the lifting path.

[0013] The lifting position of the battery mounting part is obtained by detecting the movement position of the drive unit.

[0014] In this technical solution, the position of one fixing member is matched with a first preset lifting position; that is, when the follower moves with the drive unit to a position corresponding to the fixing member, the battery mounting part moves to the first preset lifting position. The position of the other fixing member is matched with a second preset lifting position; that is, when the follower moves with the drive unit to a position corresponding to the other fixing member, the battery mounting part moves to the second preset lifting position. By matching the positions of the fixing members with the first and second preset lifting positions of the battery mounting part, the movement position of the drive unit reflects the movement position of the battery mounting part, thereby facilitating the control of the lifting of the battery mounting part.

[0015] Preferably, the first preset lifting position is the highest position of the battery mounting part on the lifting path; the second preset lifting position is the lowest position of the battery mounting part on the lifting path.

[0016] In this technical solution, the position of one fixing member corresponds to the first preset lifting position, that is, the highest position of the battery mounting part on the lifting path; the position of the other fixing member corresponds to the second preset lifting position, that is, the lowest position of the battery mounting part on the lifting path. That is, when the follower moves with the drive unit to the position corresponding to one of the fixing members, the battery mounting part is exactly at the highest or lowest position. The fixing member can sense the follower, allowing the lifting device to control the movement of the drive unit based on the signal sensed by the fixing member. This includes controlling the drive unit to stop, keeping the battery mounting part at the preset position, and preventing the drive unit from continuing to move and causing the battery mounting part to deviate from the preset position, or causing impact and equipment damage. The lifting process of the battery mounting part is controlled by detecting the lowest and highest positions of the battery mounting part, resulting in a simple structure and convenient control.

[0017] Preferably, the two ends of the motion path of the drive unit have a first limit position and a second limit position, and the two fixing members are spaced apart within the range of the first limit position and the second limit position;

[0018] The battery mounting part has a highest position and a lowest position at the upper and lower ends of the lifting path. When the battery mounting part moves to the highest position or the lowest position, the follower is located between the two fixed parts.

[0019] In this technical solution, the drive unit moves the follower between two fixed members. The follower does not move to a position corresponding to a fixed member and thus not be detected by the fixed member. This ensures that the movement path of the battery mounting unit covers both the highest and lowest positions, completing the lifting and lowering of the battery mounting unit. During normal operation of the lifting device, the follower cannot be detected by the fixed members. If the drive unit moves the battery mounting unit to the highest or lowest position and continues moving, when the drive unit moves the follower to a position corresponding to either fixed member, the fixed member can detect the follower. The detection component can then control the movement of the drive unit based on the signal detected by the fixed member, including stopping the drive unit to prevent further damage to the battery mounting unit or other structures of the battery swapping equipment, thus providing stroke protection.

[0020] The fixing members are positioned within the range of the first and second extreme positions of the drive unit, including the case where both fixing members are located at the first and second extreme positions respectively. Positioning the two fixing members between the first and second extreme positions provides a safe margin of movement for the drive unit, improving the safety of its movement. Alternatively, positioning the two fixing members at the first and second extreme positions respectively results in a compact lifting device structure.

[0021] Preferably, the fixing member is a Hall sensor, and the follower member is made of a metal that can be sensed by the Hall sensor. When the follower member moves to a position corresponding to the fixing member, the fixing member senses the follower member.

[0022] In this technical solution, a Hall sensor is used to detect the movement of the drive unit. The technology is mature, the structure is simple, and the cost is low.

[0023] Preferably, the movement path of the drive unit is consistent with the extension direction of one edge of the battery mounting unit.

[0024] In this technical solution, the direction of movement of the drive unit is consistent with the extension direction of the battery mounting unit on one side, that is, the drive unit and the battery mounting unit are arranged side by side, which makes the structure between the lifting device and the battery mounting unit compact and saves space for the battery swapping equipment.

[0025] Preferably, the motion path of the drive unit is a straight line.

[0026] In this technical solution, the drive is performed by linear motion, which saves space and helps to reduce the size of the battery swapping equipment.

[0027] Preferably, the driving unit includes a lead screw and a sliding member, the sliding member being threadedly connected to the lead screw and slidable along the length direction of the lead screw, the follower being disposed on the sliding member, and the fixing members being spaced apart along the length direction of the lead screw.

[0028] In this technical solution, a lead screw structure is used for transmission, resulting in a large reduction ratio. This facilitates the use of a high-speed motor for drive, significantly reducing the size of the drive motor. Furthermore, the lead screw transmission is compact, making the lifting device structurally compact.

[0029] Preferably, the drive unit further includes a guide member, and the slider is slidably connected to the guide member;

[0030] The fixing member is disposed on the outside of the guide member and the sliding member, and the follower member is disposed on the side edge of the sliding member near the fixing member.

[0031] In this technical solution, the slider slides along the lead screw under the drive of the lead screw, and simultaneously slides along the guide, which improves the stability of the slider's sliding. The fixing member is located on the outside of the guide and the slider to prevent the fixing member from affecting the slider's sliding along the guide. The follower is located on the edge of the slider near the fixing member, reducing the distance between the follower and the fixing member, and facilitating the fixing member's sensing of the follower.

[0032] Preferably, the lifting device further includes a lifting member for connection with the battery mounting portion, and the driving unit drives the lifting member to move and move the battery mounting portion up and down.

[0033] In this technical solution, a lifting component is provided to connect the drive unit and the battery mounting unit, making the arrangement of the drive unit and the battery mounting unit flexible.

[0034] Preferably, the first end of the lifting member is rotatably connected to the frame via a rotating shaft, the second end of the lifting member is rotatably connected to the battery mounting portion, and the driving portion is connected to the rotating shaft to drive the lifting member to rotate by rotating the rotating shaft.

[0035] The detection component also includes a lifting position detection mechanism, which is arranged corresponding to the rotation axis and is used to detect the position of the lifting component.

[0036] In this technical solution, the drive unit drives the rotating shaft to rotate, which in turn drives the lifting component to rotate. The second end of the lifting component is rotatably connected to the battery mounting part, enabling the battery mounting part to move up and down. The lifting component is connected to the rotating shaft, and a lifting position detection mechanism is set corresponding to the rotating shaft. By detecting the movement position of the rotating shaft, the movement position of the lifting component is obtained, thereby obtaining the movement position of the battery mounting part. Based on the position information of the battery mounting part, the movement of the drive unit is controlled to achieve control of the lifting and lowering of the battery mounting part.

[0037] Preferably, the detection component is used to detect the rotational position of the rotating shaft to obtain the position of the lifting member.

[0038] In this technical solution, the position of the lifting component is obtained by detecting the rotational position of the rotating shaft, which is a simple detection method.

[0039] Preferably, the lifting position detection mechanism includes a lifting detection fixing part and a lifting detection follower part. The lifting detection fixing part is fixed on the frame, and the lifting detection follower part is connected to the rotating shaft and rotates synchronously with the rotating shaft. The lifting detection fixing part senses the lifting detection follower part to detect the rotation position of the rotating shaft.

[0040] In this technical solution, a lifting detection fixing part is used to detect the position of the lifting detection follower part, thereby detecting the position of the rotating shaft. This structure is simple, reliable, and easy to implement. The position information of the rotating shaft can be transmitted through the lifting detection fixing part, allowing the lifting detection follower part to be set to a small size. The lifting detection follower part of the drive unit detection assembly is coaxially arranged with the lifting component, ensuring the synchronization between the lifting detection follower part and the lifting component. This ensures that the rotation of the lifting component detected by the detection assembly is without deviation, directly reflecting whether the battery mounting part has been lifted and lowered correctly.

[0041] Preferably, the lifting detection follow-up part has a first follow-up point and / or a second follow-up point, the first follow-up point and / or the second follow-up point are set on the rotating shaft at positions corresponding to a first preset lifting position and / or a second preset lifting position on the lifting path of the battery mounting part, and the lifting detection fixing part is used to sense the first follow-up point and / or the second follow-up point that rotate synchronously with the rotating shaft.

[0042] In this technical solution, the first follow-up point and the second follow-up point correspond to the first preset lifting position and the second preset lifting position of the battery mounting part, respectively. That is, when the rotating shaft drives the first follow-up point on the lifting detection follow-up part to rotate to the position corresponding to the lifting detection fixing part, the lifting detection fixing part senses the first follow-up point, and at this time the battery mounting part moves to the first preset lifting position; when the rotating shaft drives the second follow-up point on the lifting detection follow-up part to rotate to the position corresponding to the lifting detection fixing part, the lifting detection fixing part senses the second follow-up point, and at this time the battery mounting part moves to the second preset lifting position.

[0043] Preferably, the first preset lifting position is the highest position of the battery mounting part on the lifting path; the second preset lifting position is the lowest position of the battery mounting part on the lifting path.

[0044] In this technical solution, two lifting detection follow-up parts are set up to correspond to the highest and lowest positions of the lifting path of the battery mounting part, respectively. After the battery mounting part is lifted or lowered into place, the drive part stops moving to avoid the drive part continuing to drive the battery mounting part to lift or lower, which would cause the battery mounting part to deviate from the preset position or damage the lifting device, thereby improving the safety of the lifting device.

[0045] Preferably, the number of lifting components is multiple, and the lifting device further includes a synchronization mechanism. The drive unit is simultaneously connected to multiple lifting components through the synchronization mechanism and drives multiple lifting components to move synchronously. At least one of the lifting components has a corresponding lifting position detection mechanism on its rotation axis.

[0046] In this technical solution, multiple lifting components are provided, and a synchronization mechanism enables these components to move synchronously, lifting the battery mounting section smoothly. Each lifting component moves synchronously, and at least one rotating axis is equipped with a detection component to monitor the lifting status of the battery mounting section.

[0047] A battery swapping device includes the lifting device described in any of the foregoing technical solutions.

[0048] Preferably, the movement path of the drive unit is perpendicular to the walking path of the battery swapping device.

[0049] In this technical solution, the motion path of the drive unit is perpendicular to the walking path of the battery swapping equipment. This facilitates the staggered arrangement of the power and transmission components that enable the battery swapping equipment to move with the drive unit, thereby avoiding excessive unidirectional size of the battery swapping equipment and making the structure of the battery swapping equipment compact.

[0050] A battery swapping station comprising the battery swapping equipment described in any of the foregoing technical solutions.

[0051] The positive and progressive effects of this invention are as follows:

[0052] By setting up a detection component to detect the position of the drive unit, the lifting and lowering of the battery mounting unit can be controlled based on the movement of the drive unit, achieving precise control of the battery mounting unit's movement. Alternatively, the positions of two fixing components can be set to provide stroke protection. A follower component is mounted on the drive unit, ensuring good synchronization with it, making the drive unit's movement detected by the detection component accurate. Attached Figure Description

[0095] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0096] Example 1

[0097] Figures 1-13 This is a schematic diagram of the structure of the battery swapping device 100 provided in Embodiment 1 of the present invention.

[0098] like Figure 1 , Figure 2 As shown, the battery swapping equipment 100 includes a lifting device 1, a frame 3, and a battery mounting part 2. The battery mounting part 2 is disposed within the frame 3, and the lifting device 1 is mounted on the frame 3 and connected to the battery mounting part 2 to drive the battery mounting part 2 to rise and fall.

[0099] The lifting device 1 includes a drive unit and a detection component. The drive unit moves along a preset motion path and drives the battery mounting section 2 of the battery swapping equipment 100 to rise and fall relative to the frame 3. The detection component includes a stroke detection mechanism 40 for detecting the movement position of the drive unit. Specifically, the stroke detection mechanism 40 includes two fixed members 41 spaced apart on the motion path of the drive unit and a follower member 42 disposed on the drive unit. The fixed members 41 sense the follower member 42 to detect the movement position of the drive unit.

[0100] When the follower 42 moves with the drive unit to a position corresponding to the fixed member 41, the fixed member 41 can sense the follower 42. By setting a stroke detection mechanism 40 to detect the movement position of the drive unit, and by detecting the position of the drive unit to reflect the position of the battery mounting part 2, the lifting and lowering detection of the battery mounting part 2 is achieved. Furthermore, the movement of the drive unit is controlled according to the sensing signal from the fixed member 41, including controlling the drive unit to stop, to achieve control over the movement of the battery mounting part 2, making the lifting and lowering of the battery mounting part 2 smooth. By setting the follower 42 on the drive unit to detect the movement of the drive unit, the synchronization between the follower 42 and the drive unit is ensured, making the movement of the drive unit detected by the drive unit detection assembly accurate.

[0101] like Figures 3-5 , Figure 9 , Figure 10As shown, the drive unit includes a motor 11, a lead screw 12, a slider 13, a guide 14, and a synchronization mechanism 15. The synchronization mechanism 15 includes a chain 17, two sprockets 18, and two tension adjustment parts 16. The motor 11 is fixed to the frame 3 and connected to the lead screw 12, driving the lead screw 12 to rotate. The slider 13 is threadedly connected to the lead screw 12 and can slide along the length of the lead screw 12 under its drive. The slider 13 is fixedly connected to the tension adjustment parts 16 provided on the chain 17 through a connecting part 19, and can drive the tension adjustment parts 16 to move in the sliding direction of the slider 13. In turn, the tension adjustment parts 16 drive the chain 17 to move, thereby driving the sprockets 18 on both sides to rotate synchronously.

[0102] In this embodiment, the connecting part 19 is provided with a groove that matches the hexagonal bolt structure of the tension adjustment part 16. By partially embedding the tension adjustment part 16 into the groove of the connecting part 19, the connecting part 19 can drive the chain 17 to move.

[0103] like Figure 10 , Figure 12 As shown, the lifting device 1 also includes a lifting component 30 and two rotating shafts 20. The two rotating shafts 20 are mounted on the frame 3 and are respectively positioned corresponding to two sprockets 18. The two sprockets 18 are fixedly connected to the two rotating shafts 20 and can drive the rotating shafts 20 to rotate relative to the frame 3. Figure 13 As shown, the lifting component 30 includes a cam 31 and a cylindrical extension 32. One end of the cam 31 is fixed to the rotating shaft 20 and can rotate synchronously with the rotating shaft 20. The extension 32 is fixed to the other end of the cam 31 and installed in the slide groove 33, and can slide along the slide groove 33. The slide groove 33 is fixedly connected to the battery mounting part 2. The rotating shaft 20 rotates under the drive of the sprocket 18, which drives the cam 31 to rotate. The rotation of the cam 31 drives the extension 32 to move. The extension 32 follows the rotation of the cam 31 and slides in the slide groove 33, thereby driving the slide groove 33 and the battery mounting part 2 to rise and fall.

[0104] In this embodiment, motor 11 is used for driving. In other embodiments, the specific structure of the drive unit may differ from that of this embodiment. In other embodiments, other power drives, such as cylinders, may also be used.

[0105] In this embodiment, a lead screw 12 structure is used for transmission, which has a large reduction ratio, making it easier to use a smaller power motor 11 for driving, thereby reducing the size of the drive motor 11. Moreover, the lead screw 12 transmission has a small volume, making the lifting device 1 compact in structure.

[0106] In this embodiment, a lead screw 12 and a slider 13 are used for transmission. The slider 13 moves along a straight line, and transmission is achieved through linear motion, saving space and reducing the size of the power swapping equipment 100. In other embodiments, a gear and rack system or other transmission structures can be used for linear transmission. In other embodiments, a gear system can be used for rotary transmission, or other structures can be used for non-linear transmission.

[0107] In this embodiment, the slider 13 and the guide 14 form a sliding pair. While sliding along the lead screw 12 under the drive of the lead screw 12, the slider 13 can also slide along the guide 14, thereby improving the stability of the slider 13's movement. Furthermore, there are two guides 14, specifically two parallel slide rails. By providing two guides 14, the stability of the slider 13's movement is further improved. In other embodiments, the guides 14 may not be provided, or other methods may be used to improve the stability of the slider 13's movement.

[0108] In this embodiment, a tension adjustment part 16 is provided to adjust the tension of the chain 17; and the chain 17 and the slider 13 are connected through the tension adjustment part 16 to transmit the power of the motor 11 to the chain 17. In other embodiments, the tension adjustment part 16 and the connecting part 19 may not be provided, and the chain 17 may be moved directly by the slider 13.

[0109] like Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 12 As shown, the battery swapping equipment 100 includes a control module and two lifting devices 1. The two lifting devices 1 are respectively arranged on both sides of the battery mounting part 2. Each lifting device 1 has two lifting parts 30. The control module controls the two lifting devices 1 to move synchronously. The synchronization mechanism 15 makes the two lifting parts 30 in each lifting device 1 move synchronously, so that the four lifting parts 30 of the battery swapping equipment 100 lift the battery mounting part 2 synchronously, making the battery mounting part 2 rise and fall smoothly.

[0110] In this embodiment, the horizontal travel path of the power swapping device 100 is perpendicular to the axial direction of the lead screw 12, which facilitates the staggered arrangement of the power and transmission components that enable the power swapping device 100 to move with the drive unit, so as to avoid the power swapping device 100 having an excessively large unidirectional size and make the structure of the power swapping device 100 compact.

[0111] In this embodiment, the lifting device 1 is arranged along one edge of the battery mounting portion 2, that is, the drive unit and the battery mounting portion 2 are arranged side by side, making the structure between the lifting device 1 and the battery mounting portion 2 compact and saving space in the battery swapping equipment 100. The movement path of the sliding member 13 in the lifting device 1 is consistent with the extension direction of the side edge of the battery mounting portion 2, making the structure between the lifting device 1 and the battery mounting portion 2 even more compact. In other embodiments, the number of lifting devices 1 and their positions relative to the battery mounting portion 2 may differ from this embodiment. Correspondingly, the movement path of the drive unit and the travel path of the battery swapping equipment 100 may also differ from this embodiment. In other embodiments, a lifting device 1 may be provided with one or more lifting members 30.

[0112] In this embodiment, a lifting member 30 is provided to connect the drive unit and the battery mounting unit 2, so that the drive unit and the battery mounting unit 2 can be arranged flexibly.

[0113] In this embodiment, a sprocket 18 and a chain 17 are used to achieve synchronous movement of the two lifting components 30 in a single lifting device 1. In other embodiments, a belt drive structure or other transmission structure may be used, or multiple lifting components 30 may move synchronously by electrical signal control of a control module.

[0114] The battery mounting section 2 has a highest position and a lowest position on the lifting path. When the battery pack is being disassembled or assembled, the battery mounting section 2 is at the highest position; before the battery pack is disassembled or assembled, the battery mounting section 2 is at the origin position, and after the battery pack is disassembled or assembled, the battery mounting section 2 needs to be lowered to the origin position.

[0115] In this embodiment, the travel detection mechanism 40 of the detection component includes two fixing members 41 and one follower member 42. The position of one fixing member 41 on the movement path matches the first preset lifting position of the battery mounting part 2 on the lifting path, and the position of the other fixing member 41 on the movement path matches the second preset lifting position of the battery mounting part 2 on the lifting path.

[0116] One fixing member 41 is positioned to match a first preset lifting position. That is, when the follower member 42 moves with the drive unit to a position corresponding to the fixing member 41, the battery mounting part 2 moves to the first preset lifting position. The other fixing member 41 is positioned to match a second preset lifting position. That is, when the follower member 42 moves with the drive unit to a position corresponding to the other fixing member 41, the battery mounting part 2 moves to the second preset lifting position. By matching the positions of the fixing members 41 with the first and second preset lifting positions of the battery mounting part 2, the movement position of the drive unit reflects the movement position of the battery mounting part 2, thereby facilitating the control of the lifting of the battery mounting part 2.

[0117] Specifically, the first preset lifting position is the highest position; the second preset lifting position is the lowest position. That is, of the two fixing members 41, one matches the lowest position of the battery mounting part 2, and the other matches the highest position of the battery mounting part 2. By matching the position of the fixing member 41 with the highest and lowest positions of the battery mounting part 2, when the battery mounting part 2 moves to the highest or lowest position, the fixing member 41 can sense the follower member 42, which facilitates the control of the drive unit movement based on the signal sensed by the fixing member 41, including controlling the drive unit to stop, so that the battery mounting part 2 stays at the preset position, avoiding the drive unit from continuing to move and causing the battery mounting part 2 to deviate from the preset position, or causing impact and equipment damage. The control of the lifting process of the battery mounting part 2 is completed by detecting the lowest and highest positions of the battery mounting part 2, which is simple in structure and convenient in control.

[0118] In other embodiments, the number of fixing members 41 may differ from that in this embodiment, and the positions of the fixing members 41 may correspond to other positions on the lifting path of the battery mounting part 2. The lifting device 1 controls the lifting process of the battery mounting part 2 by detecting other positions of the battery mounting part 2 on the lifting path. In this embodiment, the fixing member 41 is a Hall sensor, and the follower 42 is made of metal that can be sensed by the Hall sensor. When the follower 42 moves to the position corresponding to the fixing member 41, the fixing member 41 senses the follower 42. Using a Hall sensor to detect the movement of the drive unit is a mature technology with a simple structure and low cost. In other embodiments, other sensors may also be used to detect the movement position of the drive unit.

[0119] like Figure 5 , Figure 6 As shown, in this embodiment, the fixing member 41 is disposed on the outside of the guide member 14 and the sliding member 13 to prevent the fixing member 41 from affecting the sliding member 13 sliding along the guide member 14. The follower member 42 is disposed on the edge of the sliding member 13 near the fixing member 41 to reduce the distance between the follower member 42 and the fixing member 41, making it easier for the fixing member 41 to sense the follower member 42. In other embodiments, the arrangement of the fixing member 41 and the follower member 42 in the drive unit may be different from that in this embodiment, and the stroke detection mechanism 40 may also obtain the movement position of the battery mounting part 2 by detecting the movement position of other components of the drive unit.

[0120] Furthermore, in this embodiment, the detection component also includes a lifting position detection mechanism 50. For example... Figure 11 As shown, the lifting position detection mechanism 50 includes two lifting detection fixing parts 51 and two lifting detection follower parts 52. The lifting detection fixing parts 51 are fixed on the frame 3 by the bracket 55. The lifting detection follower parts 52 are connected to the rotating shaft 20 and rotate synchronously with the rotating shaft 20. The lifting detection fixing parts 51 sense the lifting detection follower parts 52 to detect the rotation position of the rotating shaft 20.

[0121] like Figure 11 As shown, the two lifting detection follower units 52 each have a first follower point 53 and a second follower point 54; the first follower point 53 corresponds to the first preset lifting position of the battery mounting part 2, i.e., the highest position; the second follower point 54 corresponds to the second preset lifting position of the battery mounting part 2, i.e., the lowest position. Figure 10 , Figure 11 As shown, at this time, the battery mounting part 2 is in its lowest position, and the second follow-up point 54 is located at the position corresponding to the lifting detection fixing part 51. In this embodiment, both lifting detection fixing parts 51 are Hall sensors, and the materials at the first follow-up point 53 and the second follow-up point 54 are both metals that can be sensed by the Hall sensors.

[0122] Two lifting detection follow-up units 52 are set up to correspond to the highest and lowest positions of the lifting path of the battery mounting unit 2, respectively. When the battery mounting unit 2 is lifted or lowered into place, the lifting detection fixing unit 51 can sense the first follow-up point 53 or the second follow-up point 54 and send the sensed signal to the control module. The control module sends an electrical signal to the drive unit to control the drive unit to stop moving, so as to avoid the drive unit continuing to drive the battery mounting unit 2 to move, which would cause the battery mounting unit 2 to deviate from the preset position or damage the lifting device 1, thereby improving the stability and safety of the lifting device 1.

[0123] In this embodiment, the lifting detection follower 52 and the lifting member 30 are coaxially arranged and both are mounted on the rotation shaft 20. This ensures the synchronization between the lifting detection follower 52 and the lifting member 30, so that the rotation of the lifting member 30 detected by the detection component is without deviation and can directly reflect whether the lifting and lowering of the battery mounting part 2 is in place.

[0124] In this embodiment, the lifting position detection mechanism 50 is set corresponding to the rotating shaft 20. By detecting the rotation position of the rotating shaft 20, the position of the lifting member 30 is obtained, and then the position of the battery mounting part 2 is obtained, so as to control the lifting of the battery mounting part 2. The detection method is simple.

[0125] In this embodiment, the stroke detection mechanism 40 of the detection component obtains the position of the battery mounting part 2 by detecting the position of the drive unit, and the lifting position detection mechanism 50 obtains the position of the battery mounting part 2 by detecting the rotational position of the lifting member 30, i.e., the rotational axis position of the rotation shaft 20. Specifically, whether the sliding member 13 of the drive unit drives the follower 42 to move to correspond with any fixed member 41, causing the fixed member 41 to sense the follower 42 and send an electrical signal to the control module, or the rotation shaft 20 drives the first follower point 53 or the second follower point 54 on the lifting detection follower 52 to move to correspond with the position of the lifting detection fixed part 51, causing the lifting detection fixed part 51 to sense and send an electrical signal to the control module, the control module can send an electrical signal to the motor to control the motor to stop moving. At the same time, the position of the battery mounting part is obtained through the stroke detection mechanism 40 and the lifting position detection mechanism 50. Even if the stroke detection mechanism 40 or the lifting position detection mechanism 50 fails, the lifting of the battery mounting part can be correctly controlled.

[0126] In other embodiments, the detection component may also obtain the position of the lifting member 30 in other ways, such as directly detecting the position of the lifting member 30, or obtaining the position of the battery mounting part 2 by detecting the position of the driving part. Similarly, in other embodiments, the detection component may also obtain the position of the battery mounting part 2 in other ways, such as obtaining the position of the battery mounting part 2 by detecting the position of the driving part, or directly detecting the position of the battery mounting part 2.

[0127] By applying the battery swapping device 100 from any of the above embodiments to a battery swapping station, a battery swapping station capable of detecting the position of the drive unit of the lifting device 1 can be obtained. For instructions on how to apply the battery swapping device 100 to a battery swapping station, please refer to the prior art.

[0128] Example 2

[0129] The detection component in this embodiment is structurally the same as that in Embodiment 1, but the logic of the control module controlling the drive unit to stop moving is different from that in Embodiment 1.

[0130] In this embodiment, when the sliding member 13 of the drive unit moves the follower 42 to correspond to one of the fixed members 41, the fixed member 41 senses the follower 42 and sends an electrical signal to the control module. Simultaneously, the rotating shaft 20 moves the first follower point 53 or the second follower point 54 on the lifting detection follower 52 to correspond to the position of the lifting detection fixed member 51, causing the lifting detection fixed member 51 to sense and send an electrical signal to the control module. Upon receiving the electrical signals from the fixed member 41 and the lifting detection fixed member 51, the control module sends an electrical signal to the motor to stop its movement, ensuring the battery mounting part is in place. If the control module does not receive the electrical signal from the lifting detection fixed member 51 within a preset system time after receiving the signal from the fixed member 41, or if the control module does not receive the signal from the fixed member 41 within a preset system time after receiving the signal from the lifting detection fixed member 51, it indicates a sensor malfunction, a large transmission error in the drive unit, or a large transmission error in the lifting component. The control system issues an alarm signal to remind the operator to inspect or recalibrate the lifting device.

[0131] Example 3

[0132] The stroke detection mechanism 40 of the detection component in this embodiment is structurally the same as that in Embodiment 1, including two fixing members 41 and one follower member 42. The position of one fixing member 41 on the movement path matches the first preset lifting position of the battery mounting part 2 on the lifting path, and the position of the other fixing member 41 on the movement path matches the second preset lifting position of the battery mounting part 2 on the lifting path. The lifting position of the battery mounting part 2 is obtained by detecting the movement position of the drive unit. The lifting height position of the battery mounting part 2 is fed back by the movement of the drive unit. Since there are multiple motion transmissions in the middle, there will usually be errors. By adding an empirical value, the lifting height position of the battery mounting part 2 can be accurately reflected.

[0133] This embodiment improves the accuracy of reflecting the battery mounting position by correcting errors in the transmission process.

[0134] In this embodiment, the detection component does not include the lifting position detection mechanism 50 in Embodiment 1, and only the position of the drive unit reflects the lifting position of the battery mounting unit.

[0135] In other embodiments, the stroke detection mechanism 40 of this embodiment can also be used to obtain the position of the battery mounting part, while the lifting position detection mechanism 50 of embodiment 1 can be used to obtain the position of the battery mounting part. Specifically, whether the sliding member 13 of the drive unit drives the follower 42 to move to correspond with any fixed member 41, so that the fixed member 41 senses the follower 42 and sends an electrical signal to the control module, or the rotating shaft 20 drives the first follower point 53 or the second follower point 54 on the lifting detection follower 52 to move to correspond with the position of the lifting detection fixed part 51, so that the lifting detection fixed part 51 senses and sends an electrical signal to the control module, the control module can send an electrical signal to the motor to control the motor to stop moving. That is, even if the stroke detection mechanism 40 or the lifting position detection mechanism 50 fails, the lifting of the battery mounting part can be correctly controlled. At the same time, by correcting the error in the transmission process, the accuracy of reflecting the position of the battery mounting part through the position of the drive unit is improved.

[0136] Example 4

[0137] In this embodiment, the sliding member 13 has a first limit position and a second limit position at both ends of its movement path, and two fixing members 41 are spaced apart between the first limit position and the second limit position. When the battery mounting part 2 moves to the highest or lowest position, the follower 42 is located between the two fixing members 41.

[0138] The drive unit moves the follower 42 between the two fixed members 41. The follower 42 does not move to a position corresponding to a fixed member 41 and thus not be sensed by the fixed member 41, ensuring that the movement path of the battery mounting part 2 covers both the highest and lowest positions, completing the lifting and lowering of the battery mounting part 2. When the lifting device 1 is working normally, the follower 42 cannot be sensed by the fixed member 41. If the drive unit moves the battery mounting part 2 to the highest or lowest position and continues to move, when the drive unit moves the follower 42 to a position corresponding to either fixed member 41, the fixed member 41 will sense the follower 42 and send the sensed signal to the control module to control the movement of the drive unit, stopping its movement and preventing damage to the battery mounting part 2 or other structures of the battery swapping device 100. The two fixed members 41 are positioned between the first and second extreme positions, providing a safe movement margin for the drive unit and improving its safety. The structure described in this embodiment provides stroke protection.

[0139] In other embodiments, the two fasteners 41 may also be located at the first limit position and the second limit position respectively, making the structure of the lifting device 1 compact.

[0140] Furthermore, in this embodiment, the detection component also includes a lifting position detection mechanism 50, such as... Figure 11As shown, the lifting position detection mechanism 50 includes two lifting detection fixing parts 51 and two lifting detection follower parts 52. The lifting detection fixing parts 51 are fixed on the frame 3 by the bracket 55. The lifting detection follower parts 52 are connected to the rotating shaft 20 and rotate synchronously with the rotating shaft 20. The lifting detection fixing parts 51 sense the lifting detection follower parts 52 to detect the rotation position of the rotating shaft 20.

[0141] like Figure 11 As shown, the two lifting detection follower units 52 each have a first follower point 53 and a second follower point 54; the first follower point 53 corresponds to the first preset lifting position of the battery mounting part 2, i.e., the highest position; the second follower point 54 corresponds to the second preset lifting position of the battery mounting part 2, i.e., the lowest position. Figure 10 , Figure 11 As shown, at this time, the battery mounting part 2 is in its lowest position, and the second follow-up point 54 is located at the position corresponding to the lifting detection fixing part 51. In this embodiment, both lifting detection fixing parts 51 are Hall sensors, and the materials at the first follow-up point 53 and the second follow-up point 54 are both metals that can be sensed by the Hall sensors.

[0142] Two lifting detection follow-up units 52 are set up to correspond to the highest and lowest positions of the lifting path of the battery mounting unit 2, respectively. When the battery mounting unit 2 is lifted or lowered into place, the lifting detection fixing unit 51 can sense the first follow-up point 53 or the second follow-up point 54 and send the sensed signal to the control module. The control module sends an electrical signal to the drive unit to control the drive unit to stop moving, so as to avoid the drive unit continuing to drive the battery mounting unit 2 to move, which would cause the battery mounting unit 2 to deviate from the preset position or damage the lifting device 1, thereby improving the stability and safety of the lifting device 1.

[0143] In this embodiment, the lifting detection follower 52 and the lifting member 30 are coaxially arranged and both are mounted on the rotation shaft 20. This ensures the synchronization between the lifting detection follower 52 and the lifting member 30, so that the rotation of the lifting member 30 detected by the detection component is without deviation and can directly reflect whether the lifting and lowering of the battery mounting part 2 is in place.

[0144] In this embodiment, the lifting position detection mechanism 50 is set corresponding to the rotating shaft 20. By detecting the rotation position of the rotating shaft 20, the position of the lifting member 30 is obtained, and then the position of the battery mounting part 2 is obtained, so as to control the lifting of the battery mounting part 2. The detection method is simple.

[0145] In this embodiment, the stroke protection function is achieved through the position detection of the drive unit, and the precise lifting and lowering position of the battery mounting unit is achieved through the rotational position detection of the rotating shaft. This approach combines reliability and accuracy. In particular, since the drive unit position detection used for stroke protection is located at the end of the power transmission closer to the power source, and the rotating shaft position detection used for precise battery mounting unit position detection is located near the end of the power transmission, their combined operation can reflect whether the transmission mechanism between them is functioning properly.

[0146] In other embodiments, the detection component may also obtain the position of the lifting member 30 in other ways, such as directly detecting the position of the lifting member 30, or obtaining the position of the battery mounting part 2 by detecting the position of the driving part. Similarly, in other embodiments, the detection component may also obtain the position of the battery mounting part 2 in other ways, such as obtaining the position of the battery mounting part 2 by detecting the position of the driving part, or directly detecting the position of the battery mounting part 2.

[0147] By applying the battery swapping device 100 from any of the above embodiments to a battery swapping station, a battery swapping station capable of detecting the position of the drive unit of the lifting device 1 can be obtained. For instructions on how to apply the battery swapping device 100 to a battery swapping station, please refer to the prior art.

[0148] Example 5

[0149] Figure 14 This is a schematic diagram of the stroke detection mechanism 40 according to another embodiment of the present invention. Figure 14 As shown, the fixing member 41 can also be configured as a wedge shape, and the follower member 42 is configured as a wedge shape that cooperates with the stroke detection fixing member 41. When the follower member 42 moves to contact any other follower member 42, it will brake the sliding member 13, thereby stopping the drive unit from moving.

[0150] In other embodiments, other structures may be used to control the movement of the drive unit, including braking, deceleration, etc.

[0151] The other structures of the lifting device 1 and the power swapping equipment 100 in Examples 2, 3, 4 and 5 are the same as those in Example 1.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
