Description

Technical Field

[0001] This invention relates to the field of new energy battery swapping station technology, specifically to a battery swapping device applied to the enclosure of a new energy battery swapping station. Background Technology

[0002] The battery swapping station enclosure typically refers to a modular prefabricated cabin or steel structure house that forms the main structure of the station. It is not only a "protective shell" for the equipment, but also an intelligent integrated platform that integrates mechanical, electrical, control, temperature control, and safety systems. The entire battery swapping station function is integrated into a large enclosure, which is compact, occupies little space, and can be deployed quickly. It houses several important pieces of equipment: battery swapping devices, battery compartments, charging compartments, monitoring systems, etc.

[0003] Existing battery swapping stations typically install the main body of the swapping unit in a concrete pit below ground. During swapping, the vehicle is first driven into the swapping station, and then the battery pack is removed and installed from under the vehicle chassis using the swapping unit. Current swapping systems require the depleted battery to be removed from the vehicle and placed in the swapping cabinet before a fully charged battery can be retrieved for replacement. This cumbersome process significantly reduces battery swapping efficiency. Furthermore, after moving the battery under the vehicle, the battery may shake during transport, necessitating repositioning and adjustment, which further reduces the efficiency of battery swapping. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a battery swapping device applied to a battery swapping station enclosure, comprising a battery swapping station enclosure, wherein a battery swapping station is provided inside the battery swapping station enclosure, a battery swapping port is provided through the bottom of the battery swapping station, a buried protection box is fixedly installed below the battery swapping port at the bottom of the battery swapping station enclosure, a support platform is fixedly installed at the bottom of the inner cavity of the buried protection box, a rotating mechanism is installed at the upper end of the support platform, a transfer mechanism is symmetrically installed on both sides of the rotating mechanism, a battery body is placed on the transfer mechanism, the transfer mechanism includes a roller bracket symmetrically fixedly installed on the side of the rotating mechanism, a plurality of transfer rollers are equidistantly rotatably installed on the inner side of the roller bracket, a positioning mechanism for blocking the battery body is installed on the inner side of the roller bracket away from the rotating mechanism, and a stop mechanism is fixedly installed on the upper surface of the roller bracket near the rotating mechanism; A lifting and swapping mechanism is installed at one end of the support platform, which is located below the swapping port. An unlocking mechanism is installed at the other end of the support platform.

[0006] As a further embodiment of the present invention, the rotating mechanism includes a rotating platform fixedly connected to the upper end of the support platform. A cylinder is rotatably mounted on the upper end of the rotating platform via a bearing. The cylinder is driven by the motor shaft of a stepper motor fixedly mounted on the upper end of the support platform. A rotating seat is fixedly connected to the upper end of the cylinder. One end of the roller bracket is fixedly connected to the rotating seat.

[0007] As a further embodiment of the present invention, the upper end of the support platform is symmetrically and fixedly connected to an arc-shaped guide rail via a support plate, and a fan-shaped slider is fixedly installed at the bottom of the roller bracket, the fan-shaped slider being slidably connected to the arc-shaped guide rail.

[0008] As a further embodiment of the present invention, the stop mechanism includes an L-shaped limiting seat fixedly installed on the upper surface of the roller bracket near the rotating mechanism, and a plurality of balls are embedded in the inner side of the L-shaped limiting seat.

[0009] As a further embodiment of the present invention, the positioning mechanism includes a mounting base fixedly installed on the inner side of the roller support away from the rotating mechanism. The upper end of the mounting base is provided with a lifting groove. A movable frame is slidably installed in the lifting groove. A positioning frame is fixedly connected to the upper end of the movable frame. A positioning roller is rotatably connected to the upper end of the positioning frame through a bearing. A pressing block is fixedly connected to the upper end of the movable frame. An inclined surface is formed by cutting off the upper end of the pressing block. A reset mechanism is installed in the movable frame.

[0010] As a further embodiment of the present invention, the reset mechanism includes a slide rod fixedly connected inside the movable frame. The slide rod passes downward through the mounting base and extends to the outside. A reset spring is sleeved on the outside of the slide rod. The two ends of the reset spring abut against the bottom of the movable frame and the lifting groove, respectively. An L-shaped frame is fixedly connected to the bottom of the slide rod. A pressing roller is rotatably installed on the top of the horizontal plate of the L-shaped frame.

[0011] As a further embodiment of the present invention, the unlocking mechanism includes a support frame symmetrically and fixedly connected to the upper end of the support platform. An arc-shaped plate is fixedly installed at the upper end of the support frame, and the bottom of both ends of the arc-shaped plate is cut off to form a pressing slope.

[0012] As a further embodiment of the present invention, the lifting and power-swapping mechanism includes a lifting platform disposed above a support platform. Multiple bearing pads are fixedly installed on the upper end of the lifting platform, and guide rods are symmetrically fixedly connected to the lower end of the lifting platform. The guide rods penetrate the upper end of the support platform, and hydraulic cylinders are symmetrically fixedly installed on the support platform. The upper end of the inner rod of the hydraulic cylinder is fixedly connected to the bottom of the lifting platform.

[0013] The beneficial effects of this invention are: 1. When a car needs a battery swap, the upper end of the lifting battery swapping mechanism abuts against the bottom of the battery body. The servo tightening system unlocks the latches between the battery and the car, releasing the lock between the depleted battery and the car. The retraction of the inner rod of the hydraulic cylinder moves the depleted battery body above the transfer mechanism, thus completing the removal of the depleted battery body from the car. During the removal of the depleted battery body from the car, the fully charged battery body is transferred to another transfer mechanism via the battery transfer mechanism. At this time, the stop mechanism and positioning mechanism on the transfer mechanism cooperate to clamp and position the battery body on the transfer mechanism, preventing it from slipping or shifting off the transfer mechanism when the battery body rotates and moves.

[0014] 2. Start the stepper motor, which drives the two transfer mechanisms on its side to rotate 180 degrees through the rotating mechanism, thereby exchanging the positions of the two transfer mechanisms and the depleted battery body and the fully charged battery body. The depleted battery body is moved from the transfer mechanism to the charging compartment for charging through the battery transfer mechanism. At the same time, the lifting battery swapping mechanism clamps the fully charged battery body into the bottom of the car. Then, the tooling in the servo tightening system locks the buckle between the car and the car, locking the fully charged battery body between the car and the car. Then, the lifting battery swapping mechanism is reset, and finally the opening and closing door is closed, thus completing the battery swapping of the car.

[0015] 3. During the removal of the depleted battery from the vehicle, the depleted battery is moved to a transfer mechanism, while the fully charged battery is moved from the battery compartment to above another transfer mechanism. A rotating mechanism drives the two transfer mechanisms on its sides to rotate 180 degrees, thus swapping their positions. The depleted and fully charged battery are then interchanged via these two transfer mechanisms. At this point, a lifting and swapping mechanism installs the fully charged battery onto the vehicle, while the depleted battery is moved to the charging compartment for charging, significantly improving work efficiency. The shifting and positioning mechanisms on the transfer mechanisms work together to clamp and position the battery, preventing it from slipping or shifting during rotation and ensuring the accuracy and efficiency of battery installation and removal.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 9 This invention provides a technical solution: a battery swapping device applied to a battery swapping station enclosure, comprising a battery swapping station enclosure 1, a battery swapping station 11 inside the battery swapping station enclosure 1, a battery swapping port 12 extending through the bottom of the battery swapping station 11, an opening and closing door installed inside the battery swapping port 12, and a buried protection box 13 fixedly installed below the battery swapping port 12 at the bottom of the battery swapping station 11. The battery swapping station enclosure 1 contains a battery compartment, a charging compartment, a monitoring system, and a battery transfer mechanism, etc. The battery is moved from the battery compartment and the charging compartment through the battery transfer mechanism to complete the initial transfer of the battery. A notch is opened on one side of the buried protection box 13, and one end of the battery transfer mechanism extends through the notch into the buried protection box 13, thereby enabling the battery to be moved into the buried protection box 13 through the battery transfer mechanism. A support platform 2 is fixedly installed at the bottom of the inner cavity of the buried protection box 13. A rotating mechanism is installed at the upper end of the support platform 2. A transfer mechanism is symmetrically installed on both sides of the rotating mechanism. A battery body 36 is placed on the transfer mechanism. The transfer mechanism includes a roller bracket 3 symmetrically fixedly installed on the side of the rotating mechanism. Several transfer rollers 31 are equidistantly rotatably installed on the inner side of the roller bracket 3. A positioning mechanism for blocking the battery body 36 is installed on the inner side of the roller bracket 3 away from the rotating mechanism. A stop mechanism is fixedly installed on the upper surface of the roller bracket 3 near the rotating mechanism. The battery body 36 is moved onto the roller support 3 by the battery transfer mechanism. At this time, the bottom of the battery body 36 rolls along the transfer roller 31 until the battery body 36 contacts the two stop mechanisms, thus completing the transfer of the battery body 36. The two stop mechanisms and two positioning mechanisms on the transfer mechanism are used to position and clamp the battery body 36 to prevent the battery body 36 from slipping off or shifting from the transfer mechanism when the rotating mechanism drives the two transfer mechanisms to rotate. The battery transfer mechanism can be composed of a multi-degree-of-freedom robotic arm, a vision positioning system, etc., so as to accurately move the battery body 36 in the initial stage. The above-mentioned equipment is known to those skilled in the art. The specific setting can be adjusted according to actual needs, as long as the movement of the battery body 36 can be completed. A lifting battery swapping mechanism is installed at one end of the support platform 2, which is located below the battery swapping port 12. An unlocking mechanism is installed at the other end of the support platform 2. The unlocking mechanism is used to release the positioning mechanism from obstructing the battery body 36.

[0020] The battery body 36 is equipped with multiple buckle structures that connect with the vehicle, such as a T-shaped spin-pressed battery pack quick-change lock. The lifting battery swapping mechanism is equipped with multiple high-precision servo tightening systems that perform unlocking and locking, thereby completing the unlocking and locking of the buckles on the battery body 36 with the vehicle.

[0021] Please see Figures 2 to 6 The rotating mechanism includes a rotating platform 21 fixedly connected to the upper end of the support platform 2. A cylinder 22 is rotatably mounted on the upper end of the rotating platform 21 via a bearing. The cylinder 22 passes through the top of the rotating platform 21. The cylinder 22 is driven by the motor shaft of a stepper motor fixedly mounted on the upper end of the support platform 2. A rotating seat 23 is fixedly connected to the upper end of the cylinder 22. The lower end of the rotating seat 23 is in rotatable contact with the upper end of the rotating platform 21. Two transfer mechanisms are symmetrically installed on both sides of the rotating seat 23. One end of the roller bracket 3 is fixedly connected to the rotating seat 23.

[0022] Each time the stepper motor is driven, its motor shaft rotates 180 degrees, which drives the cylinder 22 to rotate. The cylinder 22 drives the rotating seat 23 to rotate 180 degrees, and the rotating seat 23 drives the two transfer mechanisms on its side to rotate 180 degrees, thereby exchanging the positions of the two transfer mechanisms. The rotating seat 23 drives the roller support 3 to rotate, and the roller support 3 drives the battery body 36 on it to move synchronously through the transmission roller 31. With the cooperation of two stop mechanisms and two positioning mechanisms, the battery body 36 can slide off or deviate from the transfer mechanism when it rotates and moves.

[0023] The upper end of the support platform 2 is symmetrically and fixedly connected to an arc-shaped guide rail 35 via a support plate. The bottom of the roller bracket 3 is fixedly installed with a fan-shaped slider 34, which is slidably connected to the arc-shaped guide rail 35. The arc-shaped guide rail 35 and the fan-shaped slider 34 have the same curvature, and both the arc-shaped guide rail 35 and the fan-shaped slider 34 are coaxial with the cylinder 22.

[0024] When the rotating seat 23 drives the roller support 3 to rotate, the roller support 3 drives the fan-shaped slider 34 at its bottom to move synchronously. The fan-shaped slider 34 slides along the arc-shaped guide rail 35, so that the roller support 3 can rotate stably, and the transfer mechanism can stably support and move the battery body 36.

[0025] Please see Figure 2 , Figures 4 to 6 The stop mechanism includes an L-shaped limit seat 32 fixedly installed on the upper surface of the roller bracket 3 near the rotating mechanism. Multiple balls 33 are embedded in the inner side of the L-shaped limit seat 32, and the balls 33 are in rolling connection with the L-shaped limit seat 32.

[0026] The L-shaped limiting seat 32 is engaged at one end corner of the battery body 36 near the rotating mechanism. By engaging the L-shaped limiting seat 32 at two adjacent sides of the end corner of the battery body 36, the ball bearing 33 abuts against the side of the battery body 36, thereby completing the positioning of the battery body 36.

[0027] Please see Figures 2 to 9 The positioning mechanism includes a mounting base 5 fixedly installed on the inner side of the roller support 3 away from the rotating mechanism. The upper end of the mounting base 5 is provided with a lifting groove 51. A movable frame 52 is slidably installed in the lifting groove 51. A positioning frame 53 is fixedly connected to the upper end of the movable frame 52. A positioning roller 54 is rotatably connected to the upper end of the positioning frame 53 through a bearing. The upper end and side of the positioning roller 54 extend to the outside of the positioning frame 53, and the positioning roller 54 contacts the side of the battery body 36. A pressing block 55 is fixedly connected to the upper end of the movable frame 52. The pressing block 55 is close to the side of the positioning frame 53 away from the rotating mechanism. The upper end of the pressing block 55 has an inclined surface formed by cutting off. A reset mechanism is installed in the movable frame 52.

[0028] When the battery body 36 moves above the roller support 3 and the transmission roller 31, the battery body 36 contacts the two stop mechanisms. The ball bearings 33 in the stop mechanisms abut against the side of the battery body 36, thereby limiting the battery body 36. During the process of the battery body 36 moving above the roller support 3, the battery body 36 first contacts the extrusion block 55 in the positioning mechanism. The battery body 36 slides along the inclined surface of the extrusion block 55 and pushes the extrusion block 55 downward. The extrusion block 55 drives the movable frame 52 to slide downward along the lifting groove 51. When the battery body 36 contacts the positioning roller 54, the battery body 36 pushes the positioning roller 54 downward. The positioning roller 54 drives the movable frame 52 to slide downward along the lifting groove 51 through the positioning frame 53. During this process, the movable frame 52 presses the reset mechanism. Once the battery body 36 has moved to the appropriate position, the two stop mechanisms limit the battery body 36. At the same time, the battery body 36 moves away from the top of the positioning mechanism. Under the action of the reset mechanism, the movable frame 52 moves upward and resets. The movable frame 52 drives the pressing block 55, the positioning frame 53, and the positioning roller 54 to move upward and reset. At this time, the positioning roller 54 rolls upward along one side of the battery body 36, so that the positioning roller 54 abuts against one side of the battery body 36, thereby completing the positioning of the battery body 36 and preventing the battery body 36 from slipping or shifting off the transfer mechanism during the transfer process.

[0029] The reset mechanism includes a slide rod 6 fixedly connected inside the movable frame 52. The slide rod 6 passes downward through the mounting base 5 and extends to the outside. The slide rod 6 and the mounting base 5 are slidably connected up and down. A reset spring 61 is sleeved on the outside of the slide rod 6. The two ends of the reset spring 61 abut against the bottom of the movable frame 52 and the lifting groove 51, respectively. The reset spring 61 applies an upward elastic force to the movable frame 52. An L-shaped frame 62 is fixedly connected to the bottom of the slide rod 6. The upper end of the L-shaped frame 62 contacts the bottom of the mounting base 5. A pressing roller 63 is rotatably installed on the top of the horizontal plate of the L-shaped frame 62.

[0030] When the reset mechanism rotates with the transfer mechanism, the reset mechanism will not come into contact with the arc-shaped guide rail 35; When the battery body 36 moves above the positioning mechanism, the movable frame 52 slides down along the lifting groove 51, and the movable frame 52 drives the slide rod 6 to slide down along the mounting base 5. At this time, the movable frame 52 compresses the return spring 61. When the battery body 36 moves away from above the positioning mechanism, the movable frame 52 slides up along the lifting groove 51 under the action of the return spring 61. The movable frame 52 drives the positioning roller 54 to move upward and reset, thus positioning the battery body 36.

[0031] Please see Figures 2 to 4 , Figure 9The unlocking mechanism includes a support frame 7 symmetrically and fixedly connected to the upper end of the support platform 2. An arc plate 71 is fixedly installed on the upper end of the support frame 7. The bottom of both ends of the arc plate 71 is cut off to form a pressing slope 72.

[0032] The diameter of the arc plate 71 is larger than the diameter of the arc guide rail 35. The arc plate 71 is coaxial with the cylinder 22. When the reset mechanism approaches the unlocking mechanism, the pressing roller 63 in the reset mechanism first contacts the pressing inclined surface 72. At this time, the pressing inclined surface 72 pushes the pressing roller 63 to move downward until the pressing roller 63 rolls into contact with the bottom of the arc plate 71. During this process, the pressing roller 63 drives the L-shaped frame 62 to move downward. The L-shaped frame 62 drives the slide rod 6 to slide downward along the mounting base 5. The slide rod 6 drives the movable frame 52 to slide downward along the lifting groove 51. The movable frame 52 drives the pressing block 55, the positioning frame 53, and the positioning roller 54 to move downward, so that the positioning mechanism releases the positioning of the battery body 36. At this time, the battery body 36 can be moved away from the top of the transfer mechanism.

[0033] Please see Figure 2 , Figure 4 and Figure 5 The lifting and swapping mechanism includes a lifting platform 4 set above the support platform 2. The lifting platform 4 is located below the swapping port 12. Multiple bearing pads 41 are fixedly installed on the upper end of the lifting platform 4. The bearing pads 41 are used to place the battery body 36 to prevent damage to the battery body 36. Guide light rods 42 are symmetrically fixedly connected to the lower end of the lifting platform 4. The guide light rods 42 pass through the upper end of the support platform 2 and are slidably connected to the support platform 2. Hydraulic cylinders 43 are symmetrically fixedly installed on the support platform 2. The upper end of the inner rod of the hydraulic cylinder 43 is fixedly connected to the bottom of the lifting platform 4.

[0034] Multiple hydraulic cylinders 43 are controlled by a hydraulic system to regulate the direction and flow of fluid, ensuring that they expand and contract with the same speed and force. Displacement sensors and a control system monitor the movement of each cylinder in real time and adjust accordingly to maintain synchronization. The control system receives feedback signals from the displacement sensors, processes them using algorithms, and adjusts the opening of the control valve assembly to achieve precise synchronization of displacement between the hydraulic cylinders 43. This adjusts the movement commands of the multiple hydraulic cylinders 43, enabling them to extend and retract synchronously.

[0035] The servo tightening system is installed on both sides of the upper end of the lifting platform 4. The servo tightening system consists of a servo motor, a servo driver, a tightening shaft, tooling and a main controller, which can perform the unlocking and locking operations between the battery body 36 and the car.

[0036] The lifting platform 4 moves up and down by extending and retracting the inner rod of the hydraulic cylinder 43. The lifting platform 4 drives the guide rod 42 to slide up and down along the support platform 2, so that the lifting platform 4 can move up and down stably, thereby enabling the battery body 36 to be disassembled and installed stably.

[0037] Working principle: When a car needs to have its battery swapped, the car is first driven to the battery swapping station 11, so that the battery body 36 with the depleted battery is above the battery swapping port 12. At this time, the transfer mechanism below the battery swapping port 12 does not have the battery body 36 placed on it.

[0038] The opening and closing door inside the battery swapping port 12 is opened, the inner rod of the hydraulic cylinder 43 extends and drives the lifting platform 4 to move upward, so that the top plate of the bearing pad 41 at the upper end of the lifting platform 4 abuts against the bottom of the battery body 36. At the same time, the tooling in the servo tightening system engages with the buckle on the battery body 36, and the buckle is unlocked from the car through the servo tightening system, so that the battery body 36 is unlocked from the car. The retraction of the inner rod of the hydraulic cylinder 43 causes the lifting platform 4 and the support pad 41 to move downwards. At this time, the battery body 36 moves downwards synchronously with the lifting platform 4 under its own gravity. After the battery body 36 moves downwards for a certain distance, the side of the battery body 36 rolls into contact with the ball bearing 33 and the positioning roller 54 until the lower end of the battery body 36 contacts the transfer roller 31. At this time, the inner rod of the hydraulic cylinder 43 continues to extend and retract, while the battery body 36 is supported by the transfer mechanism and cannot move further downwards, thus separating the battery body 36 from the support pad 41. This continues until the lifting platform 4 moves to the bottom. At this time, the inner rod of the hydraulic cylinder 43 stops retracting, thus completing the disassembly of the battery body 36 from the car.

[0039] At this time, the lifting and swapping mechanism will not affect the normal rotation of the transfer mechanism.

[0040] When disassembling the depleted battery body 36 from the car, the fully charged battery body 36 is transferred to another transfer mechanism via the battery transfer mechanism. At this time, the stop mechanism and positioning mechanism on the transfer mechanism cooperate to clamp and position the battery body 36 on the transfer mechanism to prevent it from slipping or shifting off the transfer mechanism when the battery body 36 rotates and moves.

[0041] Start the stepper motor to rotate the motor shaft 180 degrees, which causes the rotating seat 23 to drive the two transfer mechanisms on its side to rotate 180 degrees, thereby swapping the positions of the two transfer mechanisms, and thus swapping the positions of the depleted battery body 36 and the fully charged battery body 36. The depleted battery body 36 is moved from the transfer mechanism to the charging compartment for charging via the battery transfer mechanism. At the same time, the inner rod of the hydraulic cylinder 43 extends, causing the lifting platform 4 to move upward. First, the upper end of the support pad 41 contacts the bottom of the fully charged battery body 36. The inner rod of the hydraulic cylinder 43 continues to extend upward, causing the lifting platform 4 to push the fully charged battery body 36 upward through the support pad 41 until the fully charged battery body 36 is inserted into the bottom of the car. Then, the tooling in the servo tightening system locks the buckle between the car and the fully charged battery body 36. The inner rod of the hydraulic cylinder 43 then retracts, resetting the lifting platform 4 and the support pad 41. Finally, the opening and closing door closes, thus completing the battery swapping of the car.

[0042] During the disassembly of the depleted battery body 36 from the car, the depleted battery body 36 is moved to a transfer mechanism, while the fully charged battery body 36 is moved from the battery compartment to above another transfer mechanism. A rotating mechanism drives the two transfer mechanisms on its side to rotate 180 degrees, thereby exchanging the positions of the two transfer mechanisms. The positions of the depleted battery body 36 and the fully charged battery body 36 are exchanged through the two transfer mechanisms. At this time, the fully charged battery body 36 is installed on the car through a lifting battery swapping mechanism, while the depleted battery body 36 is moved to the charging compartment for charging.

[0043] When removing the depleted battery body 36 from the vehicle, the fully charged battery body 36 is simultaneously moved to a rotating position. The rotating mechanism allows the positions of the depleted battery body 36 and the fully charged battery body 36 to be quickly interchanged. Then, the fully charged battery body 36 is installed using a lifting battery swapping mechanism, which greatly improves work efficiency. The stop mechanism and positioning mechanism on the transfer mechanism work together to clamp and position the battery body 36 on the transfer mechanism, preventing it from slipping or shifting off the transfer mechanism during rotation and movement, thus ensuring the accuracy and efficiency of the installation and removal of the battery body 36.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
