Description

Technical Field

[0001] This invention relates to the field of charging and battery swapping stations, specifically to an integrated mobile charging and battery swapping station that can be rapidly deployed and relocated. Background Technology

[0002] CN202411930235.0 discloses a mobile charging and battery swapping station with a changeable form. The application describes a telescopic wheel frame on the bottom right side of the charging and battery swapping station. During installation, a balance adjustment cylinder drives a balance shaft and a series of transmission rods, causing the telescopic wheel frame to extend downwards, supporting the right end of the station and allowing the balance support wheel to rest on the inclined ground, thus ensuring horizontal installation. After installation, the front end of a combined branch plate contacts the ground, forming a slope structure. The combined branch plate is movably connected to eight retractable cavities inside a rotating bridge plate, allowing it to extend and retract. When the charging and battery swapping station is inclined to the ground, the combined branch plates are extended, with their front ends contacting the ground for support.

[0003] However, the above-mentioned applications are only suitable for flat surfaces with a unidirectional slope, limiting their applicability. In some mining or construction sites, where the ground has multiple slopes or is not unidirectionally inclined, it is difficult to adjust the above-mentioned applications to a horizontal state. The self-locking rotating wheel and the balancing support wheel are extremely low to the ground, making them difficult to move in the above-mentioned work sites. At the same time, placing the battery swapping room between the first and second charging storage compartments also increases the difficulty for vehicles to enter the battery swapping room. Therefore, this invention provides an integrated mobile charging and battery swapping station that can be quickly deployed and transferred. Summary of the Invention

[0013] Preferably, the leveling assembly includes a leveling plate, a leveling rod corresponding to the threaded cylinder, a locking head, and a support portion; the leveling plate has multiple sliding holes that match the leveling rod; both sides of the leveling plate extend upwards and are fixedly connected to the lower side of the support plate; a pair of sliding blocks protrude from the wall of the sliding holes; the leveling rod has sliding grooves corresponding to the sliding blocks, allowing the leveling rod to slide up and down along the sliding blocks; the lower end of the leveling rod is rotatably connected to the support portion, and the upper end is rotatably connected to the locking head, with damping at the rotatable connection, so that the locking head can achieve threaded connection with the inner wall of the threaded cylinder.

[0014] Preferably, the support includes a rotating ball and a floor plate; the lower side of the leveling rod has a groove that is rotatably connected to the rotating ball; the floor plate is fixedly connected to the lower side of the rotating ball so that the floor plate can rotate in any direction to conform to the ground with different slopes; multiple fixing rods are also fixedly connected to the leveling plate, and the upper end of the fixing rod is fixedly connected to the lower side of the support plate.

Detailed Implementation

[0041] Example 1

[0042] Please see Figures 1-14 The present invention provides a technical solution: such as Figures 1-2 As shown, a rapidly deployable and relocatable integrated mobile charging and battery swapping station includes a vehicle body 1, a support frame 2, a rotating device 3, a leveling device 4, multiple hydraulic cylinders 5, and multiple traction belts 6. The hydraulic cylinders 5 are fixedly connected to both sides of the vehicle body 1 along its length to support it. The support frame 2 is located on the side of the vehicle body 1 along its width, forming a battery swapping compartment 21 for vehicle battery swapping. The rotating device 3 is located on the upper side of the support frame 2, and the leveling device 4 is located inside the lower side. The traction belts 6 extend from both ends through multiple limiting grooves 11 formed in the vehicle body 1 and the support frame 2 towards the rotating device 3 and the leveling device 4, respectively, so that the leveling device 4 is raised and lowered by the rotation of the rotating device 3 and the lifting of the traction belts 6. The leveling device 4 descends to the ground to achieve automatic leveling. The traction belts 6 can be made of metal chains or other materials with high load-bearing capacity.

[0043] like Figures 2-4As shown, the rotating device 3 includes a drive assembly 31, a pair of rotating assemblies 32, and two sets of support seats 33. The support seats 33 are fixedly connected to the upper side of the support frame 2, and each set of support seats 33 corresponds to one rotating assembly 32. Each rotating assembly 32 includes a rotating rod 321, two pairs of limiting discs 322, and a first gear 323; the rotating rod 321 passes through the corresponding support seat 33 and is rotatably connected to it. Each pair of limiting discs 322 is fixedly connected to the outer wall of the rotating rod 321 and is close to both ends of the rotating rod 321; each pair of limiting discs 322 corresponds to a limiting groove 11, and the rotating rod 321 between each pair of limiting discs 322 is fixedly connected to the end of the traction belt 6 in the corresponding limiting groove 11; the traction belt 6 is gathered and wound around the rotating rod 321 or extends out of the traction belt 6 by rotating the rotating rod 321. Multiple traction belts 6 corresponding to one of the rotating rods 321 retract or extend from the lower side of the rotating rod 321, and multiple traction belts 6 corresponding to the other rotating rod 321 retract or extend from the upper side of the rotating rod 321, so that the multiple traction belts 6 retract or extend synchronously, thereby driving the leveling device 4 to rise or fall. A first gear 323 is fixedly connected to the outer wall of the middle part of each rotating rod 321.

[0044] The drive assembly 31 includes a motor 311, a first gear chain 312, and a second gear 313. The motor 311 is fixedly connected to the upper side of the support frame 2, and the drive end of the motor 311 is fixedly connected to the second gear 313. The first gear chain 312 is meshed with a pair of first gears 323 and second gears 313, so that the rotation of the first gear 323 drives the corresponding rotating rod 321 to rotate.

[0045] like Figures 4-11 As shown, the leveling device 4 includes a pair of ramps 41, a support plate 42, a locking assembly 43, and a leveling assembly 44. The pair of ramps 41 are rotatably connected to both sides of the support plate 42, assisting the vehicle in moving onto the support plate 42 for battery swapping. The locking assembly 43 is threaded to the underside of the support plate 42; the leveling assembly 44 is located below the locking assembly 43 and is fixedly connected to the support plate 42. A combined branch plate can also be installed on the side of the ramp 41 that contacts the ground to adapt to sloping ground. Specific installation methods are described in the background section and will not be elaborated further.

[0046] The support plate 42 includes a support plate 421 and a shield 422. The support plate 421 has multiple spaced threaded holes 4211, and the shield 422 is fixedly connected to the upper side of the support plate 421 to prevent foreign objects from falling into the threaded holes 4211. Multiple connecting cylinders 423 matching the traction belt 6 are also fixedly connected to both sides of the support plate 421 along its length to be fixedly connected to the traction belt 6. The connecting cylinders 423 are aligned vertically with the limiting groove 11 to ensure stability when the leveling device 4 moves up and down. The support plate 421 can be made with a honeycomb structure to reduce its weight and increase its load-bearing capacity.

[0047] The locking assembly 43 includes multiple threaded cylinders 431 corresponding to the threaded holes 4211, multiple second toothed chains 432, multiple third gears 433 corresponding to the threaded cylinders 431, and multiple limiting plates 434. Each threaded cylinder 431 is threadedly connected to the threaded hole 4211, and a third gear 433 is fixedly connected to its outer wall. The multiple threaded cylinders 431 are divided into multiple rows of threaded cylinders 431 along the length of the support plate 421. Each row of threaded cylinders 431 is fitted with a second toothed chain 432, which meshes with the third gear 433 corresponding to each row of threaded cylinders 431, so as to drive the third gear 433 and the threaded cylinder 431 of the corresponding row to rotate through the second toothed chain 432. A limiting plate 434 is provided on the lower side of each third gear 433, and the limiting plate 434 is fixedly connected to the outer wall of the corresponding threaded cylinder 431 to provide support for the second toothed chain 432.

[0048] The locking assembly 43 also includes multiple fourth gears 435 and third toothed chains 436; each fourth gear 435 corresponds to a row of threaded cylinders 431, and the fourth gears 435 are located on either side of the support plate 421 in the width direction, forming a row of fourth gears 435; the limiting plate 434 near the fourth gear 435 extends further to the lower side of the fourth gear 435 for support. The height of the fourth gear 435 is greater than that of the third gear 433, and the lower part of the fourth gear 435 meshes with the corresponding second toothed chain 432. The third toothed chain 436 is sleeved on the upper part of the multiple fourth gears 435 and meshes with them, so that the rotation of any fourth gear 435 drives the rotation of all second toothed chains 432, thereby driving the rotation of all third gears 433 and all threaded cylinders 431, realizing synchronous rotation and upward or downward movement from the threaded hole 4211. Each fourth gear 435 has a rotation hole 4351 in the middle.

[0049] A storage compartment is provided at the bottom side of the carriage 1 inside the battery swapping compartment 21. A rotating gun 12 with a round handle is placed in the storage compartment. The cross section of the rotating gun 12 matches the rotating hole 4351, so that the fourth gear 435 can be rotated by inserting the rotating gun 12 into the rotating hole 4351.

[0050] like Figure 8 and Figures 11-14As shown, the leveling assembly 44 includes a leveling plate 441, a leveling rod 442 corresponding to the threaded cylinder 431, a locking head 443, and a support part 444. The leveling plate 441 has multiple sliding holes that match the leveling rod 442. The two sides of the leveling plate 441 extend upward and are fixedly connected to the lower side of the support plate 421. A pair of sliding blocks 4411 protrude from the wall of the sliding hole. The leveling rod 442 has a sliding groove 4421 corresponding to the sliding block 4411, so that the leveling rod 442 slides up and down along the sliding block 4411. The upper end of the leveling rod 442 is connected to the locking head 443, and the specific connection method is a damped rotating connection. The lower end of the leveling rod 442 is rotatably connected to the support part 444. The diameter of the locking head 443 is larger than the diameter of the leveling rod 442, and the outer wall is threaded for threaded connection with the inner wall of the threaded cylinder 431 (wherein the damping resistance is greater than the force exerted by the threaded cylinder 431 on the locking head 443 when the locking head 443 is threadedly connected to the threaded cylinder 431, so as not to affect the threaded connection between the threaded cylinder 431 and the locking head 443).

[0051] The support part 444 includes a rotating ball 4441 and a flooring 4442; the leveling rod 442 has a groove on its lower side that matches the rotating ball 4441 for rotatable connection with the rotating ball 4441; the flooring 4442 is fixedly connected to the lower side of the rotating ball 4441 so that the flooring 4442 can rotate in any direction to fit the ground with different slopes.

[0052] Multiple fixing rods 445 are also fixedly connected to the flat plate 441. The upper end of the fixing rod 445 is fixedly connected to the lower side of the support plate 421 to keep the flat plate 441 stable and prevent deformation.

[0053] The bottom structure of the hydraulic cylinder 5 is the same as that of the support part 444, so as to adapt to the ground with different slopes.

[0054] Working principle: First, the carriage 1 is transported and leveled: The transport driver drives the vehicle to the designated location, activates hydraulic cylinder 5, and the hydraulic cylinder 5 descends to the ground to keep the carriage 1 level, replacing the vehicle's support for the carriage 1. The way the lower end of the hydraulic cylinder 5 contacts the road surface is the same as the way the support part 444 is, which can be referred to in the following description of the support part 444; it should be noted that because the road surface may not be very flat, the descent distance of each hydraulic cylinder 5 is different; the operator first activates the descent of a single hydraulic cylinder 5 so that the lower end of each hydraulic cylinder 5 is in contact with the ground (because the road surface is uneven, the descent distance of each hydraulic cylinder 5 is different), and then activates all hydraulic cylinders 5 at the same time, so that the carriage 1 is separated from the vehicle, completing the leveling of the carriage 1. The leveling of the carriage 1 is the initial leveling stage. Finally, the driver drives the vehicle away.

[0055] Then, the leveling device 4 is lowered via the rotating device 3, and further leveling is completed simultaneously. Specifically, the operator starts the motor 311, and the drive end of the motor 311 drives the second gear 313, the first gear chain 312, a pair of first gears 323, and a pair of rotating rods 321 to rotate synchronously, with the rotation directions of the pair of rotating rods 321 being opposite; as the rotating rods 321 rotate, the traction belt 6 extends, and the connecting cylinder 423 drives the leveling device 4 to move down along the limiting groove 11. During the downward movement, the floor 4442 and the rotating ball 4441 are in a vertical state; when it moves down to the road surface, since the road surface may not be very flat, the floor 4442 does not... The surface must be in contact with the road surface, or there may still be some part of the flooring 4442 not in contact with the ground. At this time, the motor 311 continues to rotate, causing the leveling device 4 to continue to move down. As the leveling device 4 moves down, the leveling rod 442 will pass through the sliding hole and move towards the threaded cylinder 431. The rotating ball 4441 will drive the flooring 4442 to rotate accordingly according to the flatness of the road surface to better fit the road surface. The operator will turn off the motor 311 after the flooring 4442 is basically in contact with the ground (this can be judged by the slack of the traction belt 6).

[0056] The leveling rod 442 is locked by locking head 443. Specifically, the operator pulls out the rotating gun 12 from the storage cavity and inserts it into the rotating hole 4351 of any of the fourth gears 435. Then, the operator rotates the rotating gun 12, which drives the third gear chain 436, the other fourth gears 435, the second gear chain 432, the third gear 433 corresponding to the second gear chain 432, and the threaded cylinder 431 to rotate. As the threaded cylinder 431 rotates, all the threaded cylinders 431 simultaneously rotate out of the threaded hole 4211 and move down to be threadedly connected to the corresponding locking head 443 to lock the leveling rod 442. This process continues until the locking head 443 at the lowest point of the road surface is threadedly connected to the corresponding threaded cylinder 431, thus locking the leveling rod 442. After that, the rotating gun 12 is pulled out. In addition to the rotating gun 12 of this application, a power tool can also be used to drive the fourth gear 435 to rotate. This is a conventional method and will not be described in detail.

[0057] Finally, the ramp 41 is flipped onto the road surface so that vehicles waiting to have their batteries swapped can walk onto the cover 422 to swap batteries.

[0058] When retracting, the operator retracts the ramp 41 and rotates it onto the cover plate 422; then inserts the rotating gun 12 back into the rotating hole 4351 of any of the fourth gears 435, and then rotates the rotating gun 12 in the opposite direction. The rotating gun 12 drives the third gear chain 436, the other fourth gears 435, the second gear chain 432, the third gear 433 corresponding to the second gear chain 432, and the threaded cylinder 431 to rotate, so that the threaded cylinder 431 disengages from the locking head 443.

[0059] The start motor 311 rotates in the reverse direction, driving the second gear 313, the first gear chain 312, a pair of first gears 323, and a pair of rotating rods 321 to rotate synchronously. As the rotating rods 321 rotate, the traction belt 6 begins to retract and drives the leveling device 4 to move upward. When the leveling device 4 moves to the bottom of the limiting groove 11, the operator aligns the connecting cylinder 423 with the limiting groove 11, causing the connecting cylinder 423 to drive the leveling device 4 to move upward along the limiting groove 11. At the same time, during the upward movement of the leveling device 4, the leveling rod 442 and the locking head 443 move downward through the sliding hole under the action of gravity. Meanwhile, the rotating ball 4441 and the flooring 4442 return to a vertical state under the action of gravity. Here, the rotating gun 12 can be continued to be rotated to confirm that all the flooring 4442 remain vertical, and then the rotating gun 12 can be pulled out.

[0060] Example 2

[0061] like Figure 15 As shown, based on Embodiment 1, a drag-reducing rod 13 is rotatably connected to the end of the rotating gun 12 away from the circular handle to reduce the resistance when the rotating gun 12 rotates.

[0062] Example 3

[0063] Based on Example 1, such as Figures 16-19 As shown, a pair of lifting grooves 4311 are provided on the inner wall of the threaded cylinder 431. An alignment component 45 is slidably connected in the lifting groove 4311 for thread alignment between the threaded cylinder 431 and the locking head 443. A push ring 4312 is also fixedly connected to the lower end of the threaded cylinder 431. The inner wall of the push ring 4312 matches the outer wall of the locking head 443.

[0064] The alignment assembly 45 includes a lifting rod 451, a synchronizing rod 452, and a positioning plate 453. The lifting rod 451 is slidably connected at both ends to the lifting groove 4311. The upper end of the synchronizing rod 452 is fixedly connected to the lower side of the lifting rod 451, and the lower end is used to insert into the synchronizing hole opened and matched in the middle of the locking head 443. The lifting rod 451 and the synchronizing rod 452 constitute a lifting structure. The locking head 443 is rotatably connected to the leveling rod 442 (due to damping resistance, a force greater than that from the damping resistance needs to be applied to drive the locking head 443 to rotate), causing the threaded cylinder 431 to rotate, which in turn drives the lifting rod 451, the synchronizing rod 452, the positioning plate 453, and the locking head 443 to rotate synchronously.

[0065] The locking head 443 also has a separation cavity, and a pushing assembly 46 is provided in the separation cavity. The pushing assembly 46 includes a pushing rod 461, a prying rod 462, and a fixing plate 463. The lower end of the fixing plate 463 is fixedly connected to the bottom of the separation cavity, and the upper end is rotatably connected to the lower side of the prying rod 462, forming a lever structure with the prying rod 462. The prying rod 462 extends out of the locking head 443. The pushing rod 461 is located on the upper side of the prying rod 462 and on the left side of the fixing plate 463, and the pushing rod 461 passes through the locking head 443. A spring is provided on the lower side of the prying rod 462 corresponding to the pushing rod 461 so that the prying rod 462 remains horizontal in its natural state. At this time, the top of the pushing rod 461 is flush with the top of the locking head 443. By pressing down the prying rod 462, the pushing rod 461 is moved upward, which can lift the positioning plate 453 so that the synchronizing rod 452 is disengaged from the synchronizing hole.

[0066] The height of the push ring 4312 is equal to the distance from the upper side of the positioning plate 453 to the upper side of the pry bar 462. The maximum upward movement height of the push bar 461 is the same as the distance between the lower side of the positioning plate 453 and the lower end of the synchronizing rod 452.

[0067] The process of threaded connection between locking head 443 and threaded cylinder 431 is as follows:

[0068] When the flooring 4442 is not in contact with the ground, the distance between the locking head 443 and the threaded cylinder 431 is the same. At this time, under the gravity of the alignment component 45, the synchronizing rod 452 is inserted into the synchronizing hole, and the threaded cylinder 431 and the locking head 443 are threadedly matched. When the flooring 4442 contacts the ground and completes the leveling, the locking head 443 moves upward and pushes the corresponding synchronizing rod 452 upward.

[0069] As the threaded cylinder 431 rotates and moves downward, it drives the locking head 443 to rotate synchronously via the synchronizing rod 452. When the threaded cylinder 431 drives the pushing ring 4312 to move downward until the lower end of the pushing ring 4312 contacts the upper side of the prying rod 462, the lower end of the threaded cylinder 431 is flush with the upper side of the positioning plate 453. As the threaded cylinder 431 continues to move downward, the pushing ring 4312 begins to press down on the prying rod 462, causing the pushing rod 461 to move upward until the pushing rod 461 lifts the positioning plate 453 until the synchronizing rod 452 disengages from the synchronizing hole. At this point, the prying rod 462 is pressed down into the separation cavity and does not extend beyond the outer wall of the locking head 443, so the threaded cylinder 431 cannot continue to drive the locking head 443 to rotate. As the threaded cylinder 431 continues to rotate, it will achieve a threaded connection with the locking head 443 through the matching thread. This continues until all the threaded cylinders 431 and their corresponding locking heads 443 are threadedly connected, which also completes the locking of the leveling rod 442.

[0070] Conversely, the threaded cylinder 431 rotates in the opposite direction to disengage from the threaded connection of the locking head 443. When the threaded cylinder 431 rotates upwards until its lower end is flush with the upper side of the positioning plate 453, it continues to rotate in the opposite direction. This causes the push rod 461 and the synchronizing rod 452 to begin moving downwards. The synchronizing rod 452 gradually moves downwards and inserts into the synchronizing hole, again driving the locking head 443 to rotate synchronously. This continues until the threaded cylinder 431 rotates upwards into the threaded hole 4211.
