Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery replacement, and in particular to a mobile rotary crane battery replacement method and system. Background Art

[0002] With the widespread popularity of battery-swap vehicles, the demand for vehicle battery swap is also increasing. Battery-swap vehicles are mainly composed of a vehicle body and a battery-swap seat. By installing a battery box on the battery-swap seat of a battery-swap vehicle, the electricity in the battery box can be used to power the battery-swap vehicle. Since traditional charging methods take a long time, battery-swap vehicles can be quickly recharged by replacing the battery box.

[0003] Due to the high cost of building fixed battery swap stations, when battery swap vehicles are swapped at mobile battery swap stations, the battery boxes are usually hoisted by a rotary lifting unit. However, when the rotary lifting unit moves the vertical arm during the battery box hoisting process, it is often accompanied by horizontal movement, which can cause the hoisted battery box to collide with other adjacent battery boxes. If the distance between adjacent charging stations is increased, the number of battery boxes accommodated in the mobile battery swap station will be small, and the battery swap capacity will be insufficient.

[0047] In this embodiment, with the development of battery-swapping vehicles 02, the demand for vehicle battery-swapping is also increasing. Battery-swapping vehicles 02 are replaced by platform components 01, which greatly improves the battery-swapping efficiency of battery-swapping vehicles 02 and is conducive to the rapid development of battery-swapping vehicles 02. However, when battery-swapping vehicles 02 are replaced by platform components 01, it is necessary to grab the battery box 13 by the rotating lifting unit 14 to achieve the battery-swapping operation. The process of moving the battery box 13 by the rotating lifting unit 14 is often accompanied by shaking, so that the battery box 13 may collide with other battery boxes 13 on the platform component 01. Figure 1 As shown, this embodiment provides a mobile rotary crane power replacement method, which may include steps S10 to S50, and each step is described in detail as follows:

[0048] In step S10, based on the platform component 01 moving to the battery swapping area, the position of the charging seat 122 without a battery box 13 on the platform component 01 can be obtained. When the platform component 01 moves, the battery box 13 on the platform component 01 can be moved closer to the middle of the platform component 01 to increase the driving safety of the platform component 01. Among them, the charging seat without a battery box can be the charging seat without a battery box that is closest to the battery swapping vehicle.

[0049] In step S20, Figure 4 As shown, based on the position of the charging seat 122 without a battery box 13, the first driving unit can drive the battery box 13 that needs to be avoided of the platform component 01 to move to the first set position on one side in the width direction of the platform component 01, and the first driving unit drives the charging seat 122 without a battery box 13 to move to the second set position in the width direction of the platform component 01. By moving the battery box 13 that needs to be avoided, a certain avoidance space can be left between the battery box 13 that needs to be avoided and the charging seat 122 without a battery box 13, and at the same time, the charging seat 122 without a battery box 13 is moved to the second set position, so that a battery replacement channel can be left near the charging seat 122 without a battery box 13, to prevent the subsequent rotary crane unit 14 from colliding when grabbing the battery box 13 on the battery replacement vehicle 02 and placing it on the platform component 01. Among them, the battery box 13 that needs to be avoided is adjacent to the charging seat 122 without a battery box 13.

[0050] In step S30, based on the platform assembly 01 being stationary in the battery exchange area, the rotary hoist unit 14 can drive the hoist 15 to grab the battery box 13 on the battery exchange vehicle 02 and move it along the battery exchange channel toward the charging seat 122 without the battery box 13.

[0051] In step S40, based on the charging seat 122 without the battery box 13 being moved to the second set position, the hoist 15 can place the captured battery box 13 on the battery swap vehicle 02 on the charging seat 122 without the battery box 13, so that the battery box 13 on the battery swap vehicle 02 can be charged on the charging seat 122 of the platform assembly 01, and also allows subsequent new battery boxes 13 to be placed on the battery swap vehicle 02.

[0052] In step S50, if Figure 3 As shown, based on the hoist 15 lowering the battery box 13 on the battery swap vehicle 02 , the hoist 15 can grab the battery box 13 of the platform assembly 01 and move it to the battery swap seat 22 of the battery swap vehicle 02 .

[0053] In this embodiment, the platform assembly 01 may include a movable platform 11, and the movable platform 11 may include a first section and a second section. The base 141 may be disposed between the first section and the second section.

[0054] Step S30 may include steps S311 to S312, and each step is described in detail as follows:

[0055] In step S311 , based on the platform assembly 01 being stationary in the battery swapping area, the rotary hoist unit 14 can drive the hoist 15 to grab the battery box 13 on the battery swapping vehicle 02 .

[0056] In step S312, based on the rotating hoist unit 14 driving the hoist 15 to grab the battery box 13 on the vehicle, the battery box 13 on the platform component 01 can be driven to switch to the first equilibrium state, and the rotating hoist unit 14 can drive the hoist 15 to grab the battery box 13 on the battery swap vehicle 02 and move it along the battery swap channel toward the charging seat 122 without the battery box 13. Among them, the first equilibrium state can include the second interval battery box 13 moves along the width direction of the platform component 01 toward the side away from the battery swap vehicle 02 to the first equilibrium position, and the charging seat 122 without the battery box 13 is in the first interval. Since the battery box 13 is heavy, when the rotary lifting unit 14 grabs the battery box 13 on the battery swap vehicle 02, the center of gravity of the platform assembly 01 may shift due to the long rotary lifting arm 142 of the rotary lifting unit 14, and even the platform assembly 01 may tilt. The battery box 13 in the second section can be driven to move to the first balance position along the width direction of the platform assembly 01 toward the side away from the battery swap vehicle 02, thereby reducing the center of gravity shift caused by the rotary lifting unit 14 grabbing the battery box 13 on the battery swap vehicle 02, so that the platform assembly 01 can maintain balance during the battery swap process.

[0057] In this embodiment, the first equilibrium state in step S312 also includes the first interval portion of the battery boxes 13 moving along the width direction of the platform assembly 01 toward the side away from the battery swap vehicle 02 to the second equilibrium position. Among them, the first interval portion of the battery boxes 13 include the battery boxes 13 in the first interval away from the charging seat 122 without the battery boxes 13, that is, the battery boxes 13 other than the battery boxes 13 that need to be avoided in the first interval. By moving the first interval portion of the battery boxes 13 along the width direction of the platform assembly 01 toward the side away from the battery swap vehicle 02 to the second equilibrium position, the center of gravity offset caused by the rotating hoist unit 14 grabbing the battery boxes 13 on the battery swap vehicle 02 is further reduced, so that the platform assembly 01 can maintain balance during the battery swap process.

[0058] In this embodiment, step S40 may include step S41 to step S42, and each step is described in detail as follows:

[0059] In step S41, based on the charging base 122 without the battery box 13 moving to the second set position, the rotary hoist unit 14 can drive the hoist 15 to grab the battery box 13 on the battery swap vehicle 02 and move it along the battery swap channel to the first battery swap position. Among them, the first battery swap position may include the battery box 13 moving along the battery swap channel to a position close to the platform assembly 01. In the process of the hoist 15 grabbing the battery box 13 on the battery swap vehicle 02 and moving it along the battery swap channel toward the platform assembly 01, due to the reduction in the distance between the battery box 13 on the battery swap vehicle 02 and the platform assembly 01, the degree of displacement of the center of gravity of the platform assembly 01 toward the battery swap vehicle 02 is reduced.

[0060] In step S42, based on the battery box 13 on the battery swap vehicle 02 moving to the first battery swap position along the battery swap channel, the battery box 13 in the second section can be driven to move to the third equilibrium position along the width direction of the platform assembly 01 toward the direction close to the battery swap vehicle 02, and the hoist 15 can place the captured battery box 13 on the battery swap vehicle 02 along the battery swap channel on the charging seat 122 without the battery box 13. When the battery box 13 on the battery swap vehicle 02 moves to the first battery swap position along the battery swap channel, the battery box 13 on the battery swap vehicle 02 has little effect on the center of gravity of the platform assembly 01. At this time, the center of gravity of the platform assembly 01 will move away from the battery swap vehicle 02 due to the movement of the battery box 13 in the second section away from the battery swap vehicle 02. Therefore, the battery box 13 in the second section can be driven to move to the fourth set position along the width direction of the platform assembly 01 toward the direction close to the battery swap vehicle 02, reducing the deviation of the center of gravity of the platform assembly 01 away from the battery swap vehicle 02, and ensuring the balance of the platform assembly 01 during the battery swap process.

[0061] In this embodiment, step S50 may include step S51 to step S53, and each step is described in detail as follows:

[0062] In step S51, based on the battery box 13 on the battery swap vehicle 02 being lowered by the hoist 15, the position of the target battery box 13 on the platform assembly 01 can be obtained. Among them, the target battery box 13 can be the available battery box 13 closest to the battery swap vehicle 02. When the position of the target battery box 13 is close to the position of the battery swap vehicle 02, the moving distance of the target battery box 13 during the process of the hoist 15 grabbing the target battery box 13 and moving it to the battery swap vehicle 02 is short, which facilitates the installation of the target battery box 13.

[0063] In step S52, based on the position of the target battery box 13, the first driving unit can drive the platform assembly 01 to move to the third set position on the side of the platform assembly 01 in the width direction of the battery box 13 that needs to be avoided, and the first driving unit can drive the target battery box 13 to move to the fourth set position in the width direction of the platform assembly 01. At this time, the target battery box 13 is adjacent to the charging seat 122 without a battery box 13, so that a certain avoidance space can be reserved near the target battery box 13. Prevent the rotating hanging unit 14 from colliding with the adjacent battery box 13 when clamping the target battery box 13.

[0064] In step S53 , based on the target battery box 13 moving to the fourth set position, the hoist 15 can be driven to clamp the target battery box 13 and move it to the battery replacement seat 22 .

[0065] In this embodiment, step S53 includes step S5311 to step S5312, and each step is described in detail as follows:

[0066] Step S5311, based on the target battery box 13 moving to the fourth set position and the target battery box 13 being on the side of the platform assembly 01 close to the battery swap vehicle 02, the hoist 15 can be driven to grab the target battery box 13. When the target battery box 13 is on the side of the platform assembly 01 close to the battery swap vehicle 02, the hoist 15 can grab the target battery box 13 from the side close to the battery swap vehicle 02 and move it toward the battery swap vehicle 02. At this time, the center of gravity of the platform assembly 01 shifts toward the direction close to the battery swap vehicle 02.

[0067] Step S5312, based on the lifting device 15 grabbing the target battery box 13, the battery box 13 away from the target battery box 13 can be driven to move to the fourth equilibrium position in the direction away from the battery swapping vehicle 02, and the center of gravity of the platform assembly 01 is reduced in the process of moving the target battery box 13. The lifting device 15 can clamp the target battery box 13 and move it to the battery swapping seat 22.

[0068] In this embodiment, step S53 may include step S5321 to step S5323, and each step is described in detail as follows:

[0069] Step S5321, based on the target battery box 13 moving to the fourth set position and the target battery box 13 being on the side of the platform assembly 01 away from the battery swap vehicle 02, the hoist 15 can be driven to grab the target battery box 13. When the target battery box 13 is on the side away from the battery swap vehicle 02, after the hoist 15 grabs the target battery box 13, it needs to move a certain distance away from the battery swap vehicle 02 to prevent the target battery box 13 from colliding with other battery boxes 13 during the process of being removed from the platform assembly 01. At this time, the center of gravity of the platform assembly 01 will shift with the movement of the target battery box 13.

[0070] Step S5322, based on the hoist 15 grabbing the target battery box 13, when the target battery box 13 moves in the direction away from the battery swap vehicle 02, the center of gravity of the platform assembly 01 will move in the direction away from the battery swap vehicle 02 along with the movement of the target battery box 13. The battery box 13 away from the target battery box 13 can be driven to move to the fifth equilibrium position in the direction close to the battery swap vehicle 02, so that the platform assembly 01 can maintain balance. The hoist 15 can clamp the target battery box 13 and move it to the second battery swap position. The second battery swap position can be the position where the platform assembly 01 is close to the battery swap vehicle 02.

[0071] Step S5323, based on the target battery box 13 moving to the second battery exchange position, the hoist 15 can be driven to clamp the target battery box 13 and move it to the battery exchange seat 22. The battery box 13 away from the target battery box 13 can be moved to the sixth equilibrium position in the direction away from the battery exchange vehicle 02. When the target battery box 13 moves from the second battery exchange position to the battery exchange seat 22, the target battery box 13 will move in the direction away from the platform assembly 01 to the battery exchange vehicle 02. At this time, the center of gravity of the platform assembly 01 will gradually tilt toward the direction close to the battery exchange vehicle 02. At this time, the battery box 13 away from the target battery box 13 can be driven to move in the direction away from the battery exchange vehicle 02 to reduce the degree of deviation of the center of the platform assembly 01 toward the battery exchange vehicle 02, thereby ensuring the balance of the platform assembly 01.

[0072] In this embodiment, step S30 may include steps S321 to S323:

[0073] Step S321, based on the platform component 01 being stationary in the battery swapping area, the height information above the platform component 01 can be obtained.

[0074] Step S322, based on the height above the battery swap area being greater than or equal to the height threshold, the rotary hoist unit 14 can drive the hoist 15 to grab the battery box 13 on the battery swap vehicle 02.

[0075] Step S323, based on the rotary lifting unit 14 driving the hoist 15 to grab the battery box 13 on the vehicle, the hoist 15 can be driven to move the grabbed battery box 13 on the battery swap vehicle 02 from above the required avoidance battery box 13 and move it toward the charging seat 122 without the battery box 13. When the height above the battery swap area is large, the hoist 15 can be driven to move the grabbed battery box 13 on the battery swap vehicle 02 from above the avoidance battery box 13 and place it on the charging seat 122 without the battery box 13, thereby reducing the moving distance of the battery box 13 on the battery swap vehicle 02 grabbed by the hoist 15, and also making the extended length of the rotary lifting arm 142 shorter, thereby reducing the degree of shaking of the battery box 13 on the battery swap vehicle 02 during the movement, and ensuring the stability of the battery swap process.

[0076] This embodiment discloses a mobile rotary crane power exchange system. The mobile rotary crane system can be applied to any of the above mobile rotary crane power exchange methods. The mobile rotary crane power exchange system may include:

[0077] The battery swap vehicle 02 may include a vehicle body 21 and a battery swap seat 22. The battery swap seat 22 is detachably connected to the end of the vehicle body 21 away from the ground. The battery box 13 may be installed on the battery swap seat 22, thereby transmitting electrical energy to the battery swap vehicle 02 through the battery swap seat 22, providing power for the battery swap vehicle 02.

[0078] Platform component 01, such as Figure 2 As shown, the platform assembly 01 may include a movable platform 11, a sliding unit 12, a battery box 13, a rotating suspension unit 14 and a sling 15. The sliding unit 12 may be arranged on the movable platform 11 and detachably connected to the movable platform 11. The sliding unit 12 may include a slide rail 121 and a charging seat 122, and the slide rail 121 is slidably connected to the charging seat 122. The battery box 13 is detachably connected to the charging seat 122. The charging seat 122 may move along the width direction of the platform assembly 01 on the slide rail 121, thereby driving the battery box 13 to move on the slide rail 121. The rotating suspension unit 14 may include a base 141 and a rotating suspension arm 142. The base 141 may be fixedly connected to one end of the rotating suspension arm 142.
