Description

Technical Field

[0001] This invention relates to a wheelbase adjustment device for battery swapping stations, and more particularly to a multi-wheelbase adjustment device. Background Technology

[0002] With the rapid development of electric vehicles, one of the major challenges facing the industry is how to quickly replenish their energy, making them as convenient as traditional gasoline vehicles. Battery swapping stations have successfully solved this problem. These stations replace the batteries in the vehicle that need charging with fully charged batteries from the battery compartment, and then send the replaced batteries back into the compartment for charging.

[0003] Because different vehicle models have different wheelbases for the front and rear wheels, the battery placement also varies. Currently, the adjustment devices are generally fixed in the position of the front wheels and can only adjust the rear wheels. In this case, the battery position cannot be located after entering the battery swapping station, and the battery cannot be removed. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides a multi-axis pitch adjustment device.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multi-axis pitch adjustment device, comprising an adjustment part, a lifting structure that can drive the adjustment part to move up and down, a moving structure that can drive the adjustment part to move horizontally, and a limiting structure that prevents the adjustment part from displacing. The limiting structure includes a first limiting rack and a second limiting rack disposed on the adjustment part, wherein the first limiting rack meshes with the second limiting rack.

[0006] The lifting structure drives the adjusting part to rise, the first limiting rack disengages from the second limiting rack, the moving structure drives the adjusting part to move horizontally, and after the adjusting part reaches the set position, the lifting structure drives the adjusting part to fall, the first limiting rack engages with the second limiting rack, restricting the movement of the adjusting part.

[0007] More specifically, the moving structure includes a moving motor, a driving wheel connected to the moving motor, a driven wheel driven to rotate by the driving wheel, a moving chain sleeved on the driving wheel and the driven wheel, and a connecting plate connected to the moving chain. The connecting plate is connected to a lifting base, and the movement of the moving chain drives the lifting base to move.

[0008] More specifically, the lifting structure is mounted on the lifting base, and the adjusting part is connected to the lifting structure.

[0009] More specifically, the lifting module includes a power motor, a power drive wheel connected to the power motor, a power driven wheel meshing with the power drive wheel, a lead screw connected to the power driven wheel, and a wedge block connected to the lead screw. The rotation of the lead screw drives the wedge block to move linearly. A lifting component is provided on the adjusting part that contacts the wedge block. As the wedge block moves horizontally, the lifting component drives the adjusting part to rise and fall.

[0010] More specifically, the lifting component is configured as a lifting roller.

[0011] More specifically, the lifting base is equipped with a positioning detection sensor for detecting when the adjustment part has risen to the correct position and a reset detection sensor for detecting when the adjustment part has reset.

[0012] More specifically, a slide rail is provided on the lifting base, and a slider is provided on the adjusting block, with the slider cooperating with the slide rail for guidance.

[0013] More specifically, a guide rail is provided below the lifting base, and a traveling wheel is provided on the lifting base. The traveling wheel contacts the guide rail and rotates along the guide rail.

[0014] More specifically, guide wheels are provided on both sides of the movable guide rail, and the guide wheels are connected to the lifting base.

[0015] More specifically, limit blocks are provided at both ends of the guide rail.

[0016] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0017] A multi-wheelbase adjustment device is installed in the battery swapping station to adjust the wheelbase between the wheels according to the vehicle model. First, the position of the adjustment part is determined according to the vehicle model. Then, the lifting structure drives the adjustment part to rise, and the second limiting rack on the adjustment part disengages from the first limiting rack. Then, the moving structure drives the adjustment part to move horizontally, increasing or decreasing the distance between the two wheels. After the adjustment part reaches the determined position, the lifting structure drives the adjustment part to fall, and the first limiting rack engages with the second limiting rack. At this time, after the vehicle enters the battery swapping station, because the first limiting rack is engaged with the second limiting rack, the wheels will not push the adjustment part to cause displacement, ensuring the fixed position of the adjustment part.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this invention. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this invention, and should not be construed as limiting the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention. The embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0033] It should be understood that the accompanying drawings are for illustrative purposes only.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0035] A multi-axis pitch adjustment device, such as Figures 1-11 As shown, the multi-wheelbase adjustment device is installed within the battery swapping station to adjust the position of the vehicle's front wheels. The device includes an adjustment section 1, a lifting structure 2 that can move the adjustment section 1 vertically, a moving structure 3 that can move the adjustment section 1 horizontally, and a limiting structure to prevent displacement of the adjustment section 1. A battery swapping platform is located below the multi-wheelbase adjustment device. Therefore, the adjustment of the adjustment section 1 will not affect the vehicle's entry into or exit from the battery swapping station. The multi-wheelbase adjustment device only positions the vehicle's front wheels so that the battery pack is positioned directly above the RGV vehicle after the vehicle has come to a complete stop. The battery swapping platform provides a driving surface for the vehicle.

[0036] like Figures 1-3As shown, the adjustment unit 1 includes a base plate 15, positioning members 16 disposed on both sides of the base plate 15, and connecting side plates 14 disposed at both ends of the base plate 15. Reinforcing ribs are provided on the connecting side plates 14 to enhance their strength. The connecting side plates 14 are connected to the lifting structure 2. The positioning members 16 can all be set as trapezoidal blocks, or a trapezoidal block can be set on one side and an inverted V-shaped block on the other side. When a trapezoidal block is set on one side and an inverted V-shaped block is set on the side closer to the vehicle to facilitate vehicle entry, and an inverted V-shaped block is set on the other side to further prevent the vehicle from moving forward. The distance between the two positioning members 16 is sufficient to place the wheels.

[0037] A fixed plate is provided on the battery swapping platform. The limiting structure includes a first limiting rack 12 disposed on the fixed plate and a second limiting rack 13 disposed on the adjusting part 1. The first limiting rack 12 and the second limiting rack 13 can mesh to restrict the movement of the adjusting part 1. The length of the first limiting rack 12 is set to meet the wheel track of any vehicle model. When the first limiting rack 12 is disengaged from the second limiting rack 13, the adjusting part 1 can move. When the first limiting rack 12 is engaged with the second limiting rack 13, the position of the adjusting part 1 is fixed. When the vehicle moves forward, the front wheels will push the adjusting part 1 to move. Because the first limiting rack 12 is engaged with the second limiting rack 13, the adjusting part 1 does not move.

[0038] like Figures 4-11 As shown, a lifting base 11 is connected to the adjustment part 1. The lifting base 11 is provided on both sides of the adjustment part 1. A lifting structure 2 is provided between the adjustment part 1 and the lifting base 11. The lifting structure 2 drives the adjustment part 1 to rise and fall. When the adjustment part 1 rises and falls, the lifting base 11 remains fixed.

[0039] The lifting structure 2 includes a power motor 21, a power drive wheel 22 connected to the power motor 21, a power driven wheel 23 meshing with the power drive wheel 22, a lead screw 24 connected to the power driven wheel 23, and a wedge block 25 connected to the lead screw 24. The power motor 21 is fixed on the side of the lifting base 1 away from the adjusting part 1. When the power motor 21 runs, it drives the power drive wheel 22 to rotate, and the power drive wheel 22 drives the power driven wheel 23 to rotate. A support frame is provided on the lifting base 11, and the lead screw 24 is mounted on the support frame and can rotate on the support frame. When the power driven wheel 23 rotates, it synchronously drives the lead screw 24 to rotate. The rotation of the lead screw drives the lead screw slider mounted on the lead screw to move horizontally, and synchronously drives the wedge block 25 connected to the lead screw slider to move linearly. A power slide rail and a power slider 27 that moves on the power slide rail are provided on the lifting base 11. The power slider 27 is connected to the lead screw slider and is used to guide the lead screw slider to ensure the horizontal movement of the lead screw slider. A guide groove is provided on the lifting base 11. The guide groove is horizontally opened, and a connecting plate is provided between the connecting screw slider and the wedge block 25. The connecting plate slides within the guide groove for guidance. A wedge block slide rail is provided on the lifting base 11, and a slider is provided on the wedge block slide rail. The slider is connected to the wedge block and guides the wedge block 25.

[0040] A lifting component, specifically a lifting roller 17, is provided on the adjusting part 1. The lifting roller 17 contacts the wedge block 25. When the wedge block 25 moves horizontally, its inclined surface causes the lifting roller 17 to rise or fall, simultaneously raising or lowering the adjusting part 1 and disengaging the first limiting rack 12 from the second limiting rack 13. To better facilitate the raising and lowering of the adjusting part 1, power guide rails 26 are provided on both sides of the lifting base 11, and power sliders 27 are provided on both sides of the adjusting part 1. When the adjusting part 1 is driven to rise and fall by the wedge block 25, the power sliders 27 cooperate with the power guide rails 26 to guide the adjusting part 1, causing it to rise and fall vertically.

[0041] To detect whether the adjustment unit 1 has been raised or lowered to the correct position, a position detection sensor 28 for detecting when the adjustment unit 1 has risen to the correct position and a reset detection sensor 29 for detecting when the adjustment unit 1 has reset are provided on the lifting base 11. A position detection block and a reset detection block are provided on the side of the adjustment unit 1 near the lifting structure 2. When the position detection sensor 28 detects the position detection block, it indicates that the adjustment unit 1 has been raised to the correct position, and the moving structure 3 can drive the adjustment unit 1 to move horizontally. When the reset detection sensor 29 detects the reset detection block, it indicates that the first limiting rack 12 and the second limiting rack 13 have engaged, and the vehicle can drive in. The positions of the detection sensors and detection blocks are not limited, as long as they can ensure detection.

[0042] To prevent the adjusting part 1 from detaching from the lifting base 11 when it moves upward, a power limiting block 18 is provided on the lifting base 11. After the adjusting part 1 rises to the correct position, the power limiting block 18 will block the adjusting part 1 from rising further, ensuring the safety of the adjusting part 1.

[0043] To further detect the synchronicity of the movement of the two sides of the adjustment part 1, a photoelectric sensor 20 is provided on the top of the lifting base 11. A transmitter is provided on the connecting side plate 14 on one side, and a receiver is provided on the connecting side plate 14 on the other side. The transmitter and receiver are on the same horizontal line. If the receiver can receive the signal emitted by the transmitter, it means that the two sides of the adjustment part 1 are moving synchronously. If the receiver does not receive the signal from the transmitter, it means that the two sides of the adjustment part 1 are not moving synchronously, either because the lifting structures 2 on both sides are not lifting synchronously, or because the moving structures 3 on both sides are not moving synchronously.

[0044] like Figures 4-11 As shown, the moving structure 3 includes a moving motor 31, a moving drive wheel 32 connected to the moving motor 31, a moving driven wheel 33 driven by the moving drive wheel 32, a moving chain 34 sleeved on the moving drive wheel 32 and the moving driven wheel 33, and a connecting plate connecting the moving chain 34 and the adjusting part 1. A gear frame is provided on the fixed plate, and the moving drive wheel 32 and the moving driven wheel 33 are respectively located at both ends of the gear frame. The distance between the moving drive wheel 32 and the moving driven wheel 33 is greater than or equal to the length of the first limiting rack 12, ensuring that the adjusting part 1 can reach any position of the first limiting rack 12. The moving motor 31 is fixed on the gear frame, and the forward or reverse rotation of the moving motor 31 causes the adjusting part 1 to move back and forth.

[0045] The connecting plate is fixed on the moving chain 34 and moves as the moving chain 34 rotates. While the connecting plate moves, it drives the adjusting part 1 to move. Since the adjusting part 1 is connected to the lifting base 11, the connecting plate is connected to the lifting base 11. While the connecting plate moves, it drives the lifting base 11 to move, and synchronously drives the adjusting part 1 to move. After the adjusting part 1 moves to a horizontal position, the lifting structure 2 will drive the adjusting part 1 to descend. At this time, the first limiting rack 12 and the second limiting rack 13 will mesh. Sometimes, the movement of the adjusting part 1 may not accurately guarantee that the first limiting rack 12 and the second limiting rack 13 will mesh after the adjusting part 1 descends. However, because each tooth on the rack is set as a trapezoidal inclined surface, the second limiting rack 13 can slide into the tooth groove of the first limiting rack 12 and mesh with it. At this time, since this solution uses a moving chain 34, when the second limiting rack 13 slides, the moving chain 34 can be directly pulled to make the moving chain 34 rotate, without causing the moving chain 34 to break. If other power sources are used, such as cylinders, the adjusting part 1 cannot move, and the meshing of the second limiting rack 13 and the first limiting rack 12 cannot be guaranteed. Of course, the moving chain 34 can also be replaced with a belt to achieve the above function.

[0046] To facilitate the horizontal movement of the lifting base 11, a movable guide rail 35, which is an I-beam guide rail, is provided below the lifting base 11. The lifting base 11 moves horizontally along the movable guide rail 35. To make the movement of the lifting base 11 smoother, several traveling wheels 111 are provided on the lifting base 11. The traveling wheels 111 are located below the lifting base 11 and are evenly distributed. The traveling wheels 111 contact the upper flange plate of the movable guide rail 35. When the moving chain 34 drives the lifting base 11 to move, the traveling wheels 111 roll on the upper surface of the upper flange plate. The traveling wheels 111 can reduce the friction between the lifting base 11 and the movable guide rail 35, and reduce the pulling force when the lifting base 11 is pulled.

[0047] To prevent the lifting base 11 from tilting or detaching from the guide rail 35 when it moves along the guide rail 35, a plurality of guide wheels 351 are provided on both sides of the lifting base 11. The guide wheels 351 are evenly distributed on both sides of the lifting base 11. The guide wheels 351 are in contact with the side of the upper flange plate. When the lifting base 11 moves, the guide wheels 351 roll along the side of the upper flange plate. The guide wheels 351 can further guide the movement of the lifting base 11 and also clamp the guide rail 35 to prevent the lifting base 11 from detaching from the guide rail 35.

[0048] To prevent the lifting base 11 from detaching from the moving guide rail 35 during movement, moving limit blocks 36 are provided at both ends of the moving guide rail 35, and moving contact blocks 37 are provided on the lifting base 11. When the lifting base 11 moves to its limit, the moving contact blocks 37 will contact the moving limit blocks 36, preventing further movement of the lifting base 11 and ensuring the safe use of the lifting base 11. A gasket is provided on the moving contact blocks 37 to provide some cushioning when the moving contact blocks 37 contact the moving limit blocks 36, preventing damage.

[0049] To better determine whether the adjustment unit 1 has reached the designated position, a position detection sensor 38 is provided on the side of the first limiting rack 12 near the lifting base 11, and a position detection block is provided on the lifting base 11. When the position detection sensor 38 detects the position detection block at the corresponding position, it indicates that the adjustment unit 1 has reached the corresponding position. Of course, the arrangement of the position detection sensor 38 and the position detection block can be changed to ensure position detection.

[0050] The specific operating steps of the multi-axis pitch adjustment structure are as follows:

[0051] When the position of the adjusting part 1 needs to be adjusted, the power motor 21 drives the wedge block 25 to move to one side, and simultaneously drives the adjusting part 1 to rise. When the positioning detection sensor 28 detects the positioning detection block, it indicates that the first limiting rack 12 and the second limiting rack 13 have disengaged. At this time, the moving motor 31 drives the moving chain 34 to rotate, and simultaneously drives the lifting base 11 to move closer to or further away from the vehicle. When the position detection sensor 38 at the corresponding position detects the positioning detection block, it indicates that the adjusting part 1 has reached the designated position. At this time, the power motor 21 drives the wedge block 25 to move to the other side, and simultaneously drives the adjusting part 1 to fall. When the reset detection sensor 29 detects the reset detection block, it indicates that the first limiting rack 12 and the second limiting rack 13 are engaged, and the wheelbase adjustment is completed.

[0052] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0053] A multi-wheelbase adjustment device is installed in the battery swapping station to adjust the wheelbase between the wheels according to the vehicle model. First, the position of the adjustment part 1 is determined according to the vehicle model. Then, the lifting structure 2 drives the adjustment part 1 to rise, and the second limiting rack 13 set on the adjustment part 1 disengages from the first limiting rack 12. Then, the moving structure 3 drives the adjustment part 1 to move horizontally, increasing or decreasing the distance between the two wheels. After the adjustment part 1 reaches the determined position, the lifting structure 2 drives the adjustment part 1 to fall, and the first limiting rack 12 engages with the second limiting rack 13. At this time, after the vehicle enters the battery swapping station, because the first limiting rack 12 and the second limiting rack 13 are engaged, the wheels will not push the adjustment part 1 to cause displacement, ensuring that the position of the adjustment part 1 is fixed.
