Description

Technical Field

[0001] This utility model belongs to the field of power battery swapping, and in particular relates to a liftable battery swapping device and a mobile battery swapping station. Background Technology

[0002] With the increasing number of new energy vehicles adopting battery swapping, such as electric heavy trucks and electric engineering vehicles, existing technologies have led to the development of mobile battery swapping stations that are more suitable for long-distance battery swapping scenarios. Compared to traditional fixed battery swapping stations, which are only suitable for short-distance concentrated vehicle battery swapping scenarios, mobile battery swapping stations do not rely on land or power facilities and can be moved at any time along with the working location of electric vehicles. However, due to road transport restrictions, the total height of mobile battery swapping stations must meet height restrictions, which narrows the range of different battery box sizes of vehicles that can be swapped using mobile battery swapping stations.

[0003] Chinese invention patent application CN118372714A discloses a mobile battery swapping vehicle, a mobile charging system, a mobile battery swapping system, and an integrated system. The mobile battery swapping vehicle includes a tractor, a trailer connected to the tractor, a battery gripping and placing device mounted on the trailer, and a control device. The control device is connected to the electronic control unit of both the battery gripping and placing device and the tractor to control the battery gripping and placing device. The battery gripping and placing device includes a traveling mechanism, a lifting mechanism mounted on the traveling mechanism, and a telescopic mechanism mounted on the lifting mechanism.

[0004] When the mobile battery swapping vehicle moves, the battery gripping and placing device is fixed at a specific position on the trailer, and the lifting mechanism is in its lowest position to meet the height restrictions for road transport. Upon reaching the location of the battery swapping vehicle, the telescopic mechanism is first controlled by the control equipment to move forward and backward along the trailer and rise and fall along the trailer's height under the action of the traveling and lifting mechanisms. Once the spreader on the telescopic mechanism reaches directly above the battery, connects to the battery, and lifts the battery to a certain height, the telescopic mechanism then extends and retracts along the trailer's left and right sides to perform the battery swap. Furthermore, to prevent the battery gripped by the device from colliding with other batteries during movement, the lifting mechanism must raise the battery to a height greater than the battery's own height. Additionally, the battery gripping and placing device is equipped with an anti-tipping locking mechanism to prevent it from tipping over after moving to the preset position on the trailer.

[0005] The problem with the aforementioned battery grabbing and placing equipment is that the lifting stroke of its lifting mechanism exceeds the height of the supporting walking mechanism by almost twice. Furthermore, the lifting mechanism only connects and guides the lifting process through the cooperation between the lifting guide rail and the guide rail groove on the walking frame of the walking mechanism. In addition, the weight of the swapping batteries is generally quite heavy, usually around several hundred kilograms. During the process of lifting the swapping battery, it may cause the swapping battery to shake. Moreover, when the swapping battery is extended outward from the trailer, the overall deflection between the walking frame and the lifting guide rail will be relatively large, making the connection between the lifting mechanism and the walking mechanism prone to compression deformation.

[0028] In order to solve the technical problems in the prior art, the basic technical concept of this utility model is to set up a main and an auxiliary set of guide modules between the liftable lifting frame and the column of the power swapping equipment, so as to reduce the overall deflection between the column and the lifting frame, prevent the lifting frame from tilting or deforming in any radial direction, and thus improve the stability and reliability during power swapping.

[0029] The present invention will be further described in detail below with reference to the embodiments.

[0030] The specific implementation method of the mobile battery swapping station provided by this utility model is as follows: A mobile battery swapping station, such as Figure 1 As shown, the system includes a tractor unit 1, a flatbed truck 2, and a control room 3. The flatbed truck 2 is equipped with a liftable battery swapping device 5, and also holds fully charged or replaced batteries 6. The liftable battery swapping device 5 is used to swap the fully charged batteries 6 on the flatbed truck 2 with the batteries on the vehicle requiring battery swapping. Specifically, the tractor unit 1 provides the power source and tows the flatbed truck 2 for relocation. The control room 3 controls the operation of the battery swapping device 5 to swap the batteries 6. The control room 3 is located on a raised platform at the front of the flatbed truck 2, while the battery swapping device 5 and batteries 6 are located on a lower platform at the rear of the flatbed truck 2.

[0031] In addition, the liftable battery swapping equipment 5 is also equipped with a liftable and tiltable housing 4, which is connected to the flatbed trolley 2. Specifically, in the front-rear direction of the flatbed trolley 2, the front and rear panels of the housing 4 are each composed of upper and lower parts. The lower part of the front and rear panels is a fixed part 402, and the upper part is an adjusting part 403. The adjusting part 403 can be raised or lowered relative to the fixed part 402 by a lifting drive device. For example, the lifting drive device is a hydraulic cylinder or a pneumatic cylinder. By connecting cylinders to the fixed parts 402 of the front and rear panels respectively, and connecting telescopic rods to the adjusting parts 403 of the front and rear panels respectively, the lifting and lowering movement of the adjusting parts 403 of the front and rear panels can be achieved by the extension and retraction of the hydraulic cylinder or the pneumatic cylinder. In the left-right direction of the flatbed trolley 2, the box body 4 includes two inverted L-shaped plates 401. The two inverted L-shaped plates 401 are arranged opposite each other and together form the left box plate, right box plate, and top cover plate of the box body 4. The two inverted L-shaped plates 401 can be rotated 90 degrees by a flipping drive device to open the box body 4. For example, the flipping drive device is a hydraulic cylinder or a pneumatic cylinder. By connecting cylinders to the adjustment parts 403 of the front box plate and the rear box plate respectively, and connecting telescopic rods to the upper half of the two inverted L-shaped plates 401 respectively, the flipping movement of either inverted L-shaped plate 401 can be achieved by the extension and retraction of the hydraulic cylinder or the pneumatic cylinder.

[0032] When the mobile battery swapping station is moved, container 4 remains enclosed to meet road height restrictions; when the mobile battery swapping station is ready to perform battery swapping, such as Figure 1 As shown, the adjustment parts 403 of the front and rear boxes are first raised under the drive of the lifting drive device. Then, according to the location of the battery swapping vehicle on site, the inverted L-shaped plate 401 on the side closest to the battery swapping vehicle is flipped upward under the drive of the flipping drive device to open the box 4, so that the lifting module 20 of the battery swapping equipment 5 can rise and extend to grab and release the battery swapping battery 6.

[0033] like Figure 2 and Figure 3 As shown, the liftable battery swapping device 5 includes four columns 7 and a lifting frame. A travel module is connected to the bottom of each column 7. A lifting drive device 17 is provided between the lifting frame and the columns 7. A main guide module and a secondary guide module are provided between the lifting frame and the columns 7. A telescopic module 19 for extending and retracting the battery swapping device 6 from the housing 4 is connected to the top of the lifting frame. A lifting device module 20 for lifting the battery swapping device 6 is connected to the telescopic module 19. Specifically, the travel module drives the lifting frame to move and stop along the front-rear direction of the flatbed trolley 2 with the columns 7. The main guide module and the secondary guide module 21 provide dual support and guidance for the lifting frame. The lifting device module 20 is used to grab and release the battery swapping device 6. The telescopic module 19 drives the lifting device module 20 and the battery swapping device 6 to extend or retract in the left-right direction of the flatbed trolley 2.

[0034] The lifting frame includes guide columns 16 corresponding to the uprights 7. The guide columns 16 are guided and engaged with the uprights 7 through a main guiding module. The main guiding module includes a main guiding component on the guide column 16 and a main guiding engagement structure on the uprights 7. Preferably, the main guiding module includes two guide rollers 26 mounted on the guide column 16 and arranged vertically. The main guiding engagement structure is a guide groove on the uprights 7. The lifting frame moves up and down along the uprights 7 by the guide rollers 26 rolling up and down along the guide groove.

[0035] Specifically, the guide roller 26 moves up and down within the guide groove via the lifting drive device 17 and the lifting chain transmission mechanism. For example... Figure 5 As shown, the lifting drive device 17 is a rigid chain lifting device mounted on the column 7. The rigid chain lifting device includes a rigid chain 28, a drive motor, and a reel. The reel is connected to the output shaft of the drive motor. The rigid chain 28 is located in the guide groove of the column 7, with one end connected to the guide post 16 and the other end connected to the reel. When using the battery swapping equipment, the drive motor is started, and the output shaft of the drive motor drives the reel to rotate forward and backward, causing the rigid chain 28 to extend and retract from the reel. The other end of the rigid chain 28 rises and falls within the guide groove of the column 7, thereby driving the guide post 16 to rise and fall along the column 7. With the guidance of the guide roller 26, the rigid chain 28 can drive the guide post 16 to rise and fall stably along the column 7, ultimately achieving stable lifting and lowering of the battery swapping device 6. In fact, the rigid chain lifting device is existing technology and is commonly used in the lifting drive of scissor lift mechanisms.

[0036] Based on the above implementation methods, such as Figure 5 As shown, two guide rollers 26 are provided, one near each end of the guide column 16. The lifting drive device 17 is installed between the two guide rollers 26 and near the lower guide roller 26. The rigid chain 28 is connected to the guide column 16 between the two guide rollers 26. In this configuration, guide rollers 26 are provided at both ends of the rigid chain 28, which helps reduce the overall deflection of the guide column 16 when lifting the battery swapping 6, making the battery swapping process smoother. Furthermore, both the rigid chain 28 and the guide rollers 26 are enclosed in the guide groove of the column 7, which helps save the size of the battery swapping equipment and protects the rigid chain 28 from the influence of the external environment or the battery, ensuring the reliability of the rigid chain 28.

[0037] Based on the above implementation methods, such as Figure 5As shown, the rigid chain 28 is connected to the guide post 16 via adjusting shims 27. Specifically, a detachable adjusting shim 27 is provided on the side of the guide post 16 near the upright post 7, and the guide post 16 is connected to the rigid chain 28 via the adjusting shim 27. When there is a deviation in the connection gap between the lifting frame and each upright post 7, the connection gap between the lifting frame and each upright post 7 can be adapted by removing and installing different numbers of adjusting shims 27, ensuring a reliable connection between the guide post and the rigid chain, thereby further reducing the overall deflection between the upright post 7 and the lifting frame, improving the guiding fit between the lifting frame and the guide groove, and enhancing the stability of the battery swapping equipment 5 during battery swapping.

[0038] Specifically, since there are four columns 7, the four lifting drive devices 17 and the lifting chain transmission mechanism are respectively installed on the four columns 7. When there is a deviation in the connection gap between the lifting frame and each column 7, the connection gap between the four guide columns 16 and each column 7 is different. At this time, the distance between the four rigid chains 28 and their corresponding guide columns 16 is inconsistent. The adjusting shims 27 can make a small adjustment between a single rigid chain 28 and the guide column, so that the overall connection between the rigid chain of the battery swapping equipment and the guide column 16 is more reliable, and the stable lifting and lowering of the battery swapping battery 6 is guaranteed.

[0039] In other embodiments, three or more guide rollers may be provided. In this case, it is preferable that the connection point between the rigid chain and the guide post is located below all the guide rollers. This facilitates installation and avoids interference between the protruding rigid chain and the guide rollers located below its connection point. Of course, the rigid chain can also connect any two guide rollers of the guide post, as long as the size of the guide groove in the post is ensured to maintain a certain distance between the guide rollers and the rigid chain to prevent interference.

[0040] In other embodiments, the guide column can be moved up and down along the column using other lifting drive methods. For example, the battery gripping and placing device described in Chinese invention patent application CN118372714A cited in the background art uses a conveyor chain lifting mechanism.

[0041] In other embodiments, the main guiding component can also be a guide slider connected to the guide column 16. The lifting frame moves up and down along the column 7 by the guide slider on the guide column 16 moving up and down along the guide groove. When the main guiding component is a guide slider, grooves can be provided on the guide slider. The grooves on the two guide sliders can still be used to achieve lifting and lowering movement using a rigid chain drive mechanism.

[0042] In other embodiments, the main guide rollers 26 or the main guide sliders can also be set to more than two, such as three or more, as long as each main guide is spaced apart along the main guide mating parts. When there are three main guides, the three guide rollers 26 or the three guide sliders can increase the guiding effect between the main guide and the main guide mating structure. At the same time, the gap between the main guides can be used to prevent the main guide from getting stuck between the main guide and the main guide mating parts due to slight deformation of the guide column 16 caused by the weight of the battery 6, thus reducing the deflection between the lifting frame and the column 7.

[0043] Compared to existing technologies, the guide rollers 26 and guide sliders have lower requirements for fitting precision than the lifting guide rails, reducing the deflection between the lifting frame and the column 7. Even if the guide column 16 deforms slightly due to the weight of the battery 6 during the lifting frame's movement carrying the battery swapping 6, it will not affect the normal lifting and lowering of the guide rollers 26 and guide sliders along the guide groove. In contrast, since the lifting guide rail and guide groove are integrally fitted, slight deformation of the lifting guide rail due to the weight of the battery swapping 6 can easily cause jamming between the lifting guide rail and guide groove, affecting normal battery swapping operations. Moreover, the lifting frame achieves its lifting and lowering movement along the column 7 by the up-and-down rolling of the guide rollers 26 along the guide groove, transforming the sliding friction between the existing lifting guide rail and guide groove into rolling friction. This significantly reduces the frictional resistance during the lifting frame's movement and improves the stability of the lifting frame's movement along the column 7.

[0044] The guiding module 21 includes a linear slide rod 24 connected to one side of the column 7 and a guide hole on the guide post 16. The guide post 16 is sleeved on the linear slide rod 24 and guides it. Preferably, the linear slide rod 24 is a round rod connected to the inner side of the column 7. The bottom of the column 1 is connected to a base 8. The bottom of the linear slide rod 24 is fixedly connected to the base 8 via a base 23. A linear bearing 25 is also provided in the guide hole. The guide post 16 is sleeved on the linear slide rod 24 via the linear bearing 25 to achieve the guiding engagement between the guide post 16 and the round rod. The linear bearing 25 is used to transition between the round rod and the guide hole, which can reduce the frictional force between the round rod and the guide hole.

[0045] The main guiding module and the auxiliary guiding module 21 work together to form a dual guide between the lifting frame and the column 7. Based on the guiding engagement between the guide column 16 and the guide groove on the column 7, the auxiliary guiding module 21 also engages with the guide column 16. Furthermore, the auxiliary guiding module 21 and the guide column 16 are coaxially arranged, which effectively reduces the overall deflection between the column 7 and the guide column 16, prevents deformation of the guide column 16, ensures reliable engagement between the guide column 16 and the guide groove, and thus improves the stability of the battery swapping process of the battery swapping equipment 5.

[0046] In other embodiments, the linear slide bar 24 may also be a rectangular slide bar. In this case, the rectangular slide bar can be directly inserted into the guide post 16 and guide the guide post 16. However, compared with the embodiment where the guide post 16 is directly sleeved on the round rod, since the round rod has no sharp edges, the fitting accuracy requirement between the round rod and the guide post 16 is lower. This helps to prevent jamming caused by slight deformation of the guide post 16.

[0047] In other embodiments, the guiding module 21 can be sleeved around the guide post 16. In this case, the guiding module 21 includes a guide sleeve and a base, with the guide sleeve fixedly connected to the base 8 of the main frame via the base. When the guide post 16 moves up and down along the column 7, one side of the guide post 16 engages with the guide groove on the column 7, and the other side of the guide post 16 engages with the guide sleeve of the guiding module 21. This prevents the battery swapping 6 from shaking during replacement. When the battery swapping 6 is extended outward from the trailer, the guiding module 21 reduces the overall deflection between the column 7 and the guide post 16, preventing compression deformation between the lifting frame and the column 7. Compared to the embodiment where the guide post 16 is directly sleeved on the round rod, sleeved guide post 16 saves more space occupied by the guiding module 21 and helps prevent interference or collision between the battery swapping 6 and the guiding module 21.

[0048] To further improve the guiding performance between column 7 and the lifting frame, such as Figure 2 , Figure 3 and Figure 4 As shown, a reinforcing beam 9 and a limiting beam 10 connect the tops of the four uprights 7, and a synchronous beam 11 connects the bottoms of the four uprights 7. The reinforcing beam 9 connects the tops of adjacent uprights 7 along the left-right direction of the flatbed trolley 2, the limiting beam 10 connects the tops of adjacent uprights 7 along the front-back direction of the flatbed trolley 2, and the synchronous beam 11 connects the adjacent bases 8 located at the bottom of the uprights 7 along the front-back direction of the flatbed trolley 2. The reinforcing beam 9, the limiting beam 10, and the synchronous beam 11 can jointly improve the connection strength between the four uprights 7, thereby improving the stability of the uprights 7 in supporting the lifting frame.

[0049] Preferably, the limiting beam 10 is a supporting angle steel. When the lifting frame carrying the battery swapping 6 is raised to a certain height, the supporting angle steel can provide a certain support for the lifting frame, which helps to prevent the lifting frame from bending and deforming due to the load of the battery swapping 6, ensures that the lifting frame and the guide groove on the column 7 are vertically guided and cooperated, and improves the stability of the battery swapping equipment 5 in the process of replacing the battery swapping 6.

[0050] Preferably, the walking module connected to the bottom of the column 7 includes two walking tracks 14 extending along the front-rear direction of the flatbed trolley 2, which are fixedly connected to both sides of the battery swapping device 6. The two walking tracks 14 are arranged parallel to each other in the left-right direction of the flatbed trolley 2, and the flatbed trolley 2 is connected to the liftable battery swapping device 5 through the two walking tracks 14. Specifically, the two walking tracks 14 are connected to the flatbed trolley 2 by pads. The pads are connected to the flatbed trolley 2 by welding, and the number of pads can be adjusted according to the length of the flatbed trolley 2. The two walking tracks 14 are fastened to the pads located on both sides of the battery swapping device 6 by pressure plate pressing and bolt fixing. When the height of the walking tracks 14 is inconsistent, shims should be used to level the walking tracks 14 to ensure that the walking tracks 14 are in a horizontal state, thereby ensuring the stability of the liftable battery swapping device 5 when moving along the walking tracks 14.

[0051] Specifically, the walking module includes walking wheels 12 connected to the base 8, a walking drive device 13 connected to the column 7, and a walking track 14. Each walking wheel 12 is also equipped with an anti-tilt device 15. The output shaft of the walking drive device 13 is connected to the wheel axle of the walking wheel 12 through a rigid chain transmission mechanism 22. The walking wheel 12 connected to the walking drive device 13 is the driving wheel, and the walking wheel 12 not connected to the walking drive device 13 is the driven wheel. The driving wheel drives the driven wheel to move along the walking track 14 through the synchronous beam 11, and each walking wheel 12 remains vertical under the action of the anti-tilt device 15.

[0052] In addition, the tops of the four guide columns 16 of the lifting frame are connected as a whole by the mounting frame 18. One end of the telescopic module 19 connected to the top of the lifting frame is connected to the mounting frame 18, and the other end is connected to the lifting module 20.

[0053] The anti-tilt device 15 is a V-shaped support member connected to the base 8 with its opening facing downwards. Based on the guiding engagement of the traveling wheels 12 and the traveling track 14, the two diagonal sections of the V-shape support each other on either side of the corresponding traveling track 14. When the lifting module carrying the battery swapping 6 is raised to a high height, the two diagonal sections of the V-shape prevent the traveling mechanism from tilting towards the battery swapping 6, thus ensuring vertical guiding engagement between the lifting frame and the guide groove on the column 7, and improving the stability of the battery swapping equipment 5 during the battery swapping process.

[0054] Preferably, the lifting drive device 17 adopts a direct-acting drive device, such as a hydraulic cylinder, pneumatic cylinder, or hydraulic motor. When the direct-acting drive device is a hydraulic cylinder, the cylinder body is connected to the column 7, and the telescopic piston rod of the hydraulic cylinder is connected to the guide column 16 of the lifting frame. The telescopic piston rod can directly drive the guide column 16 to move up and down along the column 7. Compared with the existing lifting chain drive method, the lifting drive structure can be simplified, thereby reducing the driving error, ensuring that each guide column 16 in the lifting frame lifts and lowers synchronously, and improving the stability of the battery swapping process of the battery swapping equipment 5.

[0055] In addition, the lifting module 20 is equipped with a visual positioning sensor. The visual positioning sensor can be used to control the telescopic module 19 to adjust the telescopic length and control the walking module to adjust the walking displacement so that the lifting module 20 is positioned directly above the battery swapping unit 6. This allows the lifting module 20 to smoothly and efficiently grab and place the battery swapping unit 6, reducing the time the lifting frame carries the battery swapping unit 6 in the raised state. This reduces the possibility of deformation of the lifting frame, improves the guidance between the lifting frame and the column 7, and further reduces the overall deflection between the lifting frame and the column 7, which helps to improve the reliability and stability of the battery swapping equipment 5 during use.

[0056] In fact, the walking module connected to the bottom of the column 7, the telescopic module 19 connected to the top of the lifting frame, and the lifting device module 20 connected to the telescopic module 19 are all prior art. For example, the structures of the walking module, the telescopic module 19, and the lifting device module 20 can be the same as the walking drive device, telescopic mechanism, and lifting device described in the battery gripping and placing device of application publication number CN118372714A in the cited background art. Alternatively, in other embodiments, the structures of the walking module, the telescopic module 19, and the lifting device module 20 can be the same as the walking frame walking mode, telescopic mechanism, and lifting device described in the battery swapping robot of application publication number CN119872475A.

[0057] In other embodiments, the drive device for moving the lifting frame up and down may use a drive motor. In this case, a transmission device is needed to convert the rotational torque of the drive motor's output shaft into a vertical traction force to move the lifting frame up and down. Specifically, the transmission device may be a chain drive mechanism. The structure of the chain drive mechanism and the connection method between the chain drive mechanism and the guide column 16 and the column 7 may be the same as the lifting chain drive structure described in the battery gripping and placing device of application publication number CN118372714A in the cited background art.

[0058] In other embodiments, the structure of the walking module and the anti-tilt device 15 may be the same as that of the walking mechanism and anti-tipping structure described in the battery gripping and placing device of application publication number CN118372714A in the cited prior art. Alternatively, the structure of the walking module and the anti-tilt device 15 may be the same as that of the guide assembly and the centering wheel described in a mobile battery swapping station and control method of application publication number CN114834340A.
