Technical Field

[0001] The present invention relates to the technical field of battery swapping stations, and particularly to a battery swapping equipment vehicle and a mobile battery swapping station. Background Art

[0002] Currently, most mobile battery swapping stations use a cooperation between a battery swapping equipment vehicle and a battery transport vehicle. The battery swapping equipment vehicle is equipped with battery swapping equipment, and the battery transport vehicle is equipped with multiple fully charged batteries. During the operation of the mobile battery swapping station, the battery transport vehicle is parked on one side of the battery swapping equipment vehicle, and the vehicle to be battery-swapped is parked on the other side of the battery swapping equipment vehicle. The battery swapping equipment of the battery swapping equipment vehicle can replace the empty battery on the vehicle to be battery-swapped with a fully charged battery in the empty space of the battery transport vehicle, and replace the fully charged battery on the battery transport vehicle with an empty battery on the vehicle to be battery-swapped.

[0003] In the prior art, for some batteries on vehicles to be battery-swapped with a relatively high installation position, in order to meet the battery swapping requirements, the height dimension of the battery swapping equipment needs to be set relatively large, resulting in a relatively large height dimension of the battery swapping equipment vehicle. Moreover, since the battery swapping equipment needs to transfer batteries on both sides of the battery swapping equipment vehicle, the lateral dimension of the battery swapping equipment on the battery swapping equipment vehicle needs to be set relatively large, resulting in a relatively large lateral dimension of the battery swapping equipment vehicle. Therefore, the battery swapping equipment vehicle in the prior art cannot adapt to scenarios with requirements for the height and width of transported objects, and it is inconvenient for the battery swapping equipment vehicle to transfer and transport.

[0004] Therefore, how to solve the problem that the battery swapping equipment vehicle in the prior art is inconvenient for transfer and transport has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0019] The power supply battery is arranged on the tray. The tray is arranged below the support platform, and the tray is slidably connected to the box body. The sliding direction of the tray relative to the box body is arranged horizontally.

[0020] The present invention further provides a mobile battery swapping station, which includes a battery swapping equipment vehicle and a battery transport vehicle. The battery swapping equipment vehicle is the above-mentioned battery swapping equipment vehicle, and the battery swapping equipment of the battery swapping equipment vehicle is adapted to grab a battery on one of the battery transport vehicle and the vehicle to be battery-swapped and transfer and release the battery to the other.

[0021] The battery swapping equipment vehicle provided by the present invention includes a vehicle body and battery swapping equipment. A box body with an accommodation space inside is arranged on the vehicle body, and the longitudinal direction of the box body is consistent with the longitudinal direction of the vehicle body. First openings and second openings are respectively arranged on two side walls of the box body distributed along the transverse direction of the vehicle body. The battery swapping equipment is arranged inside the box body, and the first openings and the second openings are used for the battery swapping equipment to transfer the battery on one side of the box body to the other side of the box body through the inside of the box body. That is to say, the battery swapping equipment can grab the battery on the first side of the box body and transfer the battery to the second side of the box body, and the battery swapping equipment can also grab the battery on the second side of the box body and transfer the battery to the first side of the box body.

Detailed implementation manners

[0032] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] The following combines Figures 1 to 6 to describe the battery swapping equipment vehicle of the present invention.

[0034] As Figures 1 to 6 shown, the battery swapping equipment vehicle provided by the embodiment of the present invention includes a vehicle body 1 and a battery swapping equipment 2.

[0035] Specifically, the vehicle body 1 can be a fuel vehicle or a new energy vehicle. The vehicle body 1 is selected as a standard truck, which is convenient for driving. A box 4 with an accommodation space inside is arranged on the vehicle body 1. The longitudinal direction of the box 4 is consistent with the longitudinal direction of the vehicle body 1. Refer to the direction indicated by y in Figure 1 The transverse direction of the box 4 is consistent with the transverse direction of the vehicle body 1. Refer to the direction indicated by x in Figure 1 The direction perpendicular to both the transverse direction and the longitudinal direction of the box 4 is the height direction of the box 4. Refer to the direction indicated by z in Figure 1 in

[0036] First openings and second openings are respectively arranged on the two side walls of the box 4 distributed along the transverse direction of the vehicle body 1. The battery swapping device 2 is arranged inside the box. The battery swapping device 2 can grab the battery on the first side of the box 4 and transfer the battery to the second side of the box 4. The battery swapping device 2 can also grab the battery on the second side of the box 4 and transfer the battery to the first side of the box 4. That is to say, the first openings and the second openings are used for the battery swapping device 2 to transfer the battery on one side of the box 4 to the other side of the box 4 through the inside of the box 4.

[0037] The height of the box 4 can be telescopically adjusted. By adjusting the height dimension of the box 4, the accommodation capacity of the box 4 can be increased in the height direction.

[0038] The battery swapping device 2 includes a grasping mechanism 5, a fourth driving mechanism, and a lifting device 3. The grasping mechanism 5 is used to perform grasping and releasing actions on the battery. The fourth driving mechanism is used to drive the grasping mechanism 5 to lift and move along the transverse direction of the box 4. The lifting device 3 is used to drive the fourth driving mechanism to lift.

[0039] The lifting device 3 is rotatably arranged on the box around the vertical axis so as to rotate the battery swapping device 2 to make the length direction of the battery swapping device 2 consistent with the longitudinal direction of the box 4 before the transfer.

[0040] With such an arrangement, before the battery swap equipment vehicle is put into operation, the height dimension of the box 4 can be adjusted to the maximum, and the lifting device 3 can be used to lift the fourth drive mechanism to the highest position, so that the height position of the grabbing mechanism 5 is adapted to the height dimension of the box 4 to meet the battery swap requirements. During the battery swap process, the lifting device 3 is rotated around the vertical axis to rotate the battery swap equipment 2 until the length direction of the battery swap equipment 2 is consistent with the transverse direction of the box 4, and the fourth drive mechanism is used to control the lifting or lateral displacement of the grabbing mechanism 5 to complete the battery swap action. During transfer transportation, the lifting device 3 is rotated around the vertical axis to rotate the battery swap equipment 2 until the length direction of the battery swap equipment 2 is consistent with the longitudinal direction of the box 4, so that the requirements for the transverse dimension of the box 4 can be reduced, and the transverse dimension of the box 4 can be set smaller, which can well adapt to the scene where there are requirements for the width of the transported objects. By using the lifting device 3 to lower the fourth drive mechanism to the lowest position and adjusting the height of the box 4 to the minimum, the height of the battery swap equipment vehicle can be reduced. It can adapt well to scenarios with requirements on the height of the transported objects, facilitate transfer transportation, and solve the problem of inconvenient transfer transportation of battery swap equipment vehicles in the prior art.

[0041] Specifically, the fourth driving mechanism includes a multi-stage telescopic arm 26 and a hoisting mechanism 27. The multi-stage telescopic arm 26 is arranged at the upper end of the lifting column 9. The axis of the multi-stage telescopic arm 26 is along the lateral direction of the box body 4 and can be telescoped in the lateral direction of the box body 4. The hoisting mechanism 27 is arranged at the end of the multi-stage telescopic arm 26. The wire rope of the hoisting mechanism 27 is connected to the above-mentioned grabbing mechanism 5. The multi-stage telescopic arm 26 is telescoped, which can drive the hoisting mechanism 27 and the grabbing mechanism 5 to move in the lateral direction of the box body 4. The hoisting mechanism 27 operates, which can drive the grabbing mechanism 5 to rise and fall.

[0042] The length of the wire rope of the hoisting mechanism 27 can be made long enough. Specifically, when the lifting device 3 drives the fourth driving mechanism to rise to the highest position, the length of the wire rope is greater than the distance between the multi-stage telescopic arm 26 and the ground, so that the battery exchange equipment 2 can place the battery on the ground for easier maintenance.

[0043] The multi-stage telescopic arm 26 includes a support arm, a gear rack transmission assembly and a first motor. The support arm is provided with multiple sections. Two adjacent sections of the support arm are connected by a gear rack transmission assembly, and the gear rack transmission assembly is driven by the first motor. When the first motor rotates forward, the multi-stage telescopic arm 26 can be extended to one side of the box 4. When the first motor rotates reversely, the multi-stage telescopic arm 26 can be extended to the other side of the box 4. When the battery exchange device 2 transfers batteries between the battery transport vehicle and the vehicle to be exchanged, the battery exchange device 2 and the battery do not need to rotate. The battery only needs to move laterally along the box 4, which is beneficial to improve the battery exchange efficiency and reduce the demand for surrounding space.

[0044] When the multi-stage telescopic arm 26 is in the retracted state, the length dimension of the multi-stage telescopic arm 26 and the length dimension of the grasping mechanism 5 are basically the same as the length dimension of the battery, and the width dimension of the multi-stage telescopic arm 26 and the width dimension of the grasping mechanism 5 are basically the same as the width dimension of the battery. The length dimension of the battery is much larger than the width dimension of the battery. The length direction of the multi-stage telescopic arm 26 and the length direction of the grasping mechanism 5 can be regarded as the length direction of the whole commutation device.

[0045] During the transfer transportation, by rotating the lifting device 3 relative to the box body 4 around the vertical axis, the fourth driving mechanism and the grasping mechanism 5 are driven to rotate until the length direction of the multi-stage telescopic arm 26 and the length direction of the grasping mechanism 5 are consistent with the longitudinal direction of the box body 4. It can not only make full use of the space in the longitudinal direction of the box body 4, but also reduce the requirements for the transverse dimension of the box body 4, which is beneficial to reducing the transverse dimension of the box body 4.

[0046] In addition, the limitation of the transverse dimension of the box body 4 on the length dimension of the multi-stage telescopic arm 26 is removed, which is beneficial to increasing the length dimension of the multi-stage telescopic arm 26 and increasing the bearing capacity and elongation capacity of the multi-stage telescopic arm 26.

[0047] In a specific embodiment, the lifting device 3 can be connected to the box body 4 through the slewing device 7, and the slewing axis of the slewing device 7 is arranged along the vertical direction.

[0048] The slewing device 7 includes a base 28, a slewing seat 29 and a slewing driving mechanism. The base 28 is arranged on the box body 4. The slewing seat 29 is rotatably connected to the base 28 through a slewing bearing. The slewing axis of the slewing bearing is arranged along the vertical direction. The fixed column 8 of the lifting device 3 is arranged on the slewing seat 29. The slewing driving mechanism is used to drive the slewing seat 29 to rotate relative to the base 28, so as to drive the lifting device 3 and the fourth driving mechanism to rotate.

[0049] The inner ring of the slewing bearing is fixedly connected to the base 28, and the outer ring of the slewing bearing is fixedly connected to the slewing seat 29. The slewing driving mechanism includes a second motor and a driving gear. The second motor is fixed on the slewing seat 29. The second motor is meshed and driven with the inner ring of the slewing bearing through the driving gear. When the second motor operates, it can drive the inner ring and the outer ring of the slewing bearing to rotate relative to each other, so as to drive the slewing seat 29 to rotate relative to the fixed seat.

[0050] In this embodiment, the lifting device 3 includes a fixed column 8, a lifting column 9 and a fifth driving mechanism 10.

[0051] The fixed column 8 is connected to the slewing seat 29 of the slewing device 7. The lifting column 9 is connected to the head end of the multi-stage telescopic arm 26 of the fourth driving mechanism. The fixed column 8 is slidably connected to the lifting column 9. The sliding direction of the lifting column 9 relative to the fixed column 8 is along the vertical direction. The fifth driving mechanism 10 is used to drive the lifting column 9 to slide reciprocally relative to the fixed column 8.

[0052] The fifth driving mechanism 10 can, but is not limited to, select a lead screw nut transmission mechanism, a rack and pinion transmission mechanism, a hydraulic cylinder, etc.

[0053] Referring to Figure 4 , a lead screw nut transmission mechanism is selected as the above-mentioned fifth driving mechanism 10. Specifically, the lead screw of the lead screw nut transmission mechanism can be set as a trapezoidal lead screw, which has a self-locking performance and can keep the lifting column 9 in any position. Without an additional locking mechanism, the stability of the height position where the fourth driving mechanism is located can be ensured.

[0054] In a further embodiment, an avoidance hole 11 is provided on the rotary seat 29 of the rotary device 7. The avoidance hole 11 corresponds to the lifting column 9 up and down, and the avoidance hole 11 can allow the lifting column 9 to extend vertically therein. When the lifting device 3 is used to lower the position of the fourth driving mechanism, the lifting column 9 can extend into the avoidance hole 11 of the rotary seat 29. When the requirement for the working range of the fourth driving mechanism in the vertical direction is certain, the lowest position that the fourth driving mechanism can reach during transfer transportation can be further reduced, and the height dimension of the box body 4 can be reduced.

[0055] Correspondingly, when the lowest position that the fourth driving mechanism can reach during transfer transportation and the requirement for the height dimension of the box body 4 during transfer transportation are certain, the working range of the fourth driving mechanism in the vertical direction can be increased, which is beneficial for the battery swapping equipment vehicle to serve as many new energy vehicles as possible.

[0056] When the battery swapping equipment vehicle provided by the embodiment of the present invention is in transfer transportation, its lateral dimension is less than 2.55 meters, and its height dimension is less than 4 meters, and it can drive on the road at will.

[0057] Referring to Figure 1 and Figure 2 , the box body 4 is in a cubic shape, and the dimension of the box body 4 along its longitudinal direction is greater than the dimension of the box body 4 along its lateral direction.

[0058] When the battery swapping equipment vehicle is put into operation, the battery transport vehicle can be parked on the first side of the box body 4, and the second side of the box body 4 is used to park the vehicle to be battery-swapped. The length direction of the battery on the vehicle to be battery-swapped is generally the same as the lateral direction of the vehicle to be battery-swapped. When the vehicle to be battery-swapped is parked, it is necessary to make the lateral direction of the vehicle to be battery-swapped the same as the lateral direction of the box body 4. The longitudinal direction of the battery transport vehicle is the same as the longitudinal direction of the box body 4.

[0059] Considering that a number of batteries are arranged on the battery transport vehicle, and the batteries are distributed longitudinally along the battery transport vehicle. To ensure that the grasping mechanism 5 can smoothly grasp the batteries at any position on the battery transport vehicle, the power exchange device in the embodiment of the present invention further includes a traveling device 6. The traveling device 6 is arranged between the base 28 of the slewing device 7 and the box body 4, and is used to drive the slewing device 7 to move longitudinally along the box body 4, so as to drive the fourth driving mechanism and the grasping mechanism 5 to move longitudinally along the box body 4, which is beneficial to improving the service capacity of the power exchange equipment vehicle. When the fourth driving mechanism and the grasping mechanism 5 move longitudinally along the box body 4, they can stop at a position directly opposite to any battery on the battery transport vehicle, so as to grasp the battery at the corresponding position.

[0060] The traveling device 6 includes traveling wheels and a third motor. The traveling wheels are rotatably arranged on the base 28 of the slewing device 7. There are two groups of traveling wheels, and the two groups of traveling wheels are respectively arranged on both sides of the base 28 along the transverse direction of the box body 4. Each group of traveling wheels is distributed at intervals along the longitudinal direction of the box body 4. The third motor is used to drive the traveling wheels to rotate, and under the action of the friction force between the traveling wheels and the bottom wall of the box body 4, the base 28 can be driven to move longitudinally along the box body 4.

[0061] A first guide rail is arranged on the bottom wall of the box body 4. The first guide rail extends longitudinally along the box body 4 and is matched with the traveling wheels, and can guide the movement of the base 28.

[0062] In the embodiment of the present invention, the box body 4 at least includes a top plate 12 and a pair of telescopic plate assemblies 13. The telescopic plate assemblies 13 can be telescoped in the vertical direction. The pair of telescopic plate assemblies 13 are parallel to each other and are distributed longitudinally along the box body 4. The lower ends of the pair of telescopic plate assemblies 13 are connected to the vehicle body 1, and the top plate 12 is arranged at the upper ends of the pair of telescopic plate assemblies 13. The pair of telescopic plate assemblies 13, the top plate 12 and the vehicle body 1 enclose a cylindrical structure. The two ends of the cylindrical structure in the transverse direction of the vehicle body 1 have openings, and the openings at both ends of the cylindrical structure are respectively used as the above-mentioned first opening and second opening.

[0063] In a further embodiment, the box body 4 further includes a first cover plate 14, a second cover plate 15, a first driving mechanism 16 and a second driving mechanism 17.

[0064] The first cover plate 14 and the second cover plate 15 are arranged on both sides of the top plate 12 along the transverse direction of the vehicle body 1, and the upper edges of the first cover plate 14 and the second cover plate 15 are rotatably connected to the top plate 12.

[0065] The rotation axis of the first cover plate 14 relative to the top plate 12 is along the longitudinal direction of the vehicle body 1, and the first driving mechanism 16 is used to drive the first cover plate 14 to rotate relative to the top plate 12. When a pair of telescopic plate assemblies 13 are contracted to the minimum height dimension, the first driving mechanism 16 drives the first cover plate 14 to rotate to the vertical state to close the first opening, so as to protect the devices in the box body 4 during the transfer transportation of the battery swapping equipment vehicle. When a pair of telescopic plate assemblies 13 are extended to the maximum height dimension, the first driving mechanism 16 drives the first cover plate 14 to rotate to the horizontal state. While the first opening is in the open state, it can also provide protection for the battery transport vehicle parked on the first side of the box body 4 to ensure the safety of the battery transport vehicle.

[0066] Similarly, the rotation axis of the second cover plate 15 relative to the top plate 12 is along the transverse direction of the vehicle body 1, and the second driving mechanism 17 is used to drive the second cover plate 15 to rotate relative to the top plate 12. When a pair of telescopic plate assemblies 13 are contracted to the minimum height dimension, the second driving mechanism 17 drives the second cover plate 15 to rotate to the vertical state to close the second opening, so as to protect the devices in the box body 4 during the transfer transportation of the battery swapping equipment vehicle. When a pair of telescopic plate assemblies 13 are extended to the maximum height dimension, the second driving mechanism 17 drives the second cover plate 15 to rotate to the horizontal state. While the second opening is in the open state, it can also provide protection for the vehicle to be battery-swapped parked on the second side of the box body 4 to ensure the safety of the vehicle to be battery-swapped.

[0067] Refer to Figure 6 , a lengthening part 30 is further provided at the lower ends of the first cover plate 14 and the second cover plate 15. When the first cover plate 14 and the second cover plate 15 rotate to the horizontal state, the lengthening part 30 can increase the protection area range of the first cover plate 14 and the second cover plate 15. For example, the lengthening part 30 of the second cover plate 15 can correspond to the battery on the vehicle to be battery-swapped, expanding the rain shielding range of the second cover plate 15, and can strengthen the protection of the exposed electrical connectors on the battery base 28 of the vehicle to be battery-swapped during the battery swapping process.

[0068] The telescopic plate assembly 13 includes a fixed plate 23, a sliding plate 24 and a third driving mechanism 25. The lower end of the fixed plate 23 is fixedly connected to the vehicle body 1. The sliding plate 24 is slidably connected to the fixed plate 23. The sliding direction of the sliding plate 24 relative to the fixed plate 23 is along the vertical direction. The sliding plate 24 is fixedly connected to the top plate 12. The third driving mechanism 25 is used to drive the sliding plate 24 to slide reciprocally relative to the fixed plate 23.

[0069] The third driving mechanism 25 can be a hydraulic cylinder. The axis direction of the hydraulic cylinder is arranged along the vertical direction.

When the outrigger device 18 shortens, the vehicle body 1 can be placed on the ground.

[0072] Specifically, four outrigger devices 18 are provided, and the four outrigger devices 18 respectively correspond to the four corner positions of the box body 4.

The mobile battery swapping station is not restricted by the site when put into use and can achieve self-sufficiency. After changing the site, there is no need to reconfigure the power supply facilities, effectively reducing the engineering quantity and having obvious mobility advantages.

[0080] In the implementation of the present invention, the battery swapping equipment vehicle further includes a support platform 20 and a tray, and both the support platform 20 and the tray are arranged inside the box body 4.

[0081] The support platform 20 is fixedly arranged at one end of the box body 4, and the charger, the inverter 21, the hydraulic station 22, the control system, etc. are all arranged above the support platform 20.

[0082] The power supply battery 19 is arranged on the tray, and the tray is arranged below the support platform 20, which can make full use of the internal space of the box body 4.

[0083] The tray is slidably connected to the box body 4, and the sliding direction of the tray relative to the box body 4 is arranged horizontally. By sliding the tray, the position of the power supply battery 19 can be adjusted. When it is necessary to detect or repair the power supply battery 19, the tray can be slid to the outside of the support platform 20 to expose the power supply battery 19 for convenient operation.
