Description

Technical Field

[0001] The utility model belongs to the field of electric vehicle charging and is applied to three-dimensional charging. It can effectively solve the problem of multi-layer three-dimensional charging, so that multiple electric vehicles can be charged simultaneously in a small space. Background Art

[0002] Currently, electric vehicles are charged by installing charging piles on the ground. If multiple electric vehicles are charged at the same time, they will occupy multiple ground parking spaces at the same time, which requires more and larger ground. Some large and medium-sized cities, especially the central areas, are land-scarce and cannot provide more and larger ground charging stations. This causes great inconvenience to electric vehicle users, restricts the promotion of electric vehicles, and affects the carbon emission targets of many cities.

[0003] Publication number CN213980136U, titled "A Small Stereoscopic Garage," discloses a circular parking layout with horizontal parking and access, but does not disclose technical solutions for charging electric vehicles. For example, Publication number CN116335449A, titled "A Horizontally Shifting Sunken Well Stereoscopic Garage and Its Parking and Access Method," details a circular sunken well garage with horizontal vehicle exchange. While it describes the process of moving vehicles from the entrance to the outer circular parking spaces, the garage lacks the ability to accommodate horizontal vehicle charging or independently configurable charging bays.

[0004] The patent with publication number CN114043884A discloses a new type of intelligent three-dimensional charging station, which includes a substation, cable a, a distribution box, cable b, an intelligent charging manager, cable c, a three-dimensional parking garage frame, a floor bracket, a charger, a vehicle loading plate, a busbar, a current collector, a charging gun, a surveillance camera, a lighting, and a car picker. The characteristics are: the substation connects to cable a, cable a is connected to the distribution box, the distribution box connects to cable b, cable b is connected to the intelligent charging manager, the intelligent charging manager connects to cable c, and cable c is connected to the charger on each floor along the three-dimensional parking garage frame. The charger is installed under the floor bracket of each floor, and a busbar is installed on the outside of the charger. The vehicle loading plate is stored on the floor bracket, a current collector is installed on one side of the vehicle loading plate, one end of the current collector is connected to the charging gun, and the charging gun is hung on one side of the vehicle loading plate. A surveillance camera and a lighting are installed on the top of the three-dimensional parking garage frame, and a car picker is installed on the side of the three-dimensional parking garage frame. In this way, a complete three-dimensional charging station is formed. Its prominent defects are: its structural configuration is unreasonable, the vehicle needs to be rotated during the storage and retrieval process, and after the vehicle enters the three-dimensional charging station, there is no mechanism to stably support the tray of the electric vehicle. Under vibration and other environments, the circuit contact is unstable, which in turn generates heat, reduces the charging power, and prolongs the charging time. It cannot be effectively solved, leaving safety hazards. Summary of the Invention

[0005] The purpose of the utility model is to provide a three-dimensional charging station tray stop mechanism to address the deficiencies of the existing technology, so as to solve the problem that the tray carrying electric vehicles in the existing technology is unstable under a vibration environment in the three-dimensional charging station.

[0006] The technical solutions adopted in this utility model are as follows.

[0007] A three-dimensional charging station tray stop mechanism is characterized by comprising a plurality of longitudinally arranged stop mechanism mounting beams and a plurality of rotating rods; and a plurality of charging layers are vertically arranged on the three-dimensional charging station frame.

[0008] Each charging layer includes a charging station. The left end of each charging station is equipped with an electric vehicle tray entrance and exit, and a lifting platform is provided on the left side of the frame.

[0009] or,

[0010] Each charging layer includes a charging station. The right end of each charging station is equipped with an electric vehicle tray entrance and exit, and a lifting platform is provided on the right side of the frame.

[0011] or,

[0012] Each charging layer includes two horizontally arranged charging positions. The left end of the charging position on the left is equipped with an electric vehicle tray entrance and exit, and the right end of the charging position on the right is equipped with an electric vehicle tray entrance and exit. There are lifting platforms on the left and right sides of the frame.

[0013] Each lifting platform is provided with an electric vehicle pallet moving track, a pallet moving drive device, and a laterally movable guide frame; a stop mechanism mounting beam is longitudinally provided below the inlet and outlet of each electric vehicle pallet, and a rotating rod is installed on the side surface of each stop mechanism mounting beam near the center of the bottom surface of the charging position; stop arms perpendicular to the central axis are provided at both ends of the rotating rod; a plurality of active rotating arms are installed between the two stop arms on the rotating rod, the top of each active rotating arm is located above the top surface of the stop mechanism mounting beam, and the top of each stop arm is located above the top of each active rotating arm; the rotating rod is connected to the stop mechanism mounting beam through a spring return assembly;

[0014] A plurality of stop blocks are provided on the bottom surface of the electric vehicle pallet, and the electric vehicle pallet is located in the charging position or on the electric vehicle pallet moving track; when the electric vehicle pallet is located in the charging position, each stop arm contacts a stop block; when the bottom surface of the leading frame of the lifting platform is flush with the top surface of a stop mechanism mounting beam, each active rotating arm on the rotating rod connected to the stop mechanism mounting beam is located between the front side and the rear side of the leading frame.

[0015] When the vehicle is parked and charged, the driving guide frame on the lifting platform enters the charging position first, pushes each active rotating arm laterally, drives the rotating rod to rotate, so that the top end of the stop arm is located below the stop block on the bottom surface of the electric vehicle tray; the tray movement drive device drives the electric vehicle tray to enter the charging position; the driving guide frame on the lifting platform is reset, and under the action of the spring reset assembly, the end of each stop arm is in close contact with the stop block on the bottom surface of the electric vehicle tray.

[0016] When the vehicle is picked up after charging is completed, the driving guide frame on the lifting platform enters the charging position first, pushes each active rotating arm laterally, drives the rotating rod to rotate, so that the top of each stop arm is located below the stop block on the bottom surface of the electric vehicle tray; the tray moving drive device drives the electric vehicle tray to leave the charging position; the driving guide frame on the lifting platform is reset, and each stop arm and active rotating arm are reset.

[0017] The beneficial effects of this utility model include: facilitating the entry and exit of an electric vehicle tray into a charging station. When the electric vehicle tray is in the charging station, each stop arm contacts a stop block to stabilize the tray in the charging station, ensuring stable circuit contact in environments such as vibration. The electric vehicle tray is stably positioned in the charging station, eliminating the problem of unstable circuit contact that could generate heat, reduce charging power, extend charging time, and create safety hazards. This solves the problem of unsafe charging in the prior art.

[0018] As a preferred technical solution, the rotating rod is mounted on the side surface of the stop mechanism mounting beam close to the center of the bottom surface of the charging position through a plurality of bearings.

[0019] The spring return assembly includes at least one torsion spring, each of which is arranged on a bearing.

[0020] or,

[0021] The spring return assembly includes at least one first tension spring, one end of each first tension spring is connected to a stop arm, and the other end is connected to the stop mechanism mounting beam.

[0022] or,

[0023] The spring return assembly comprises at least one second tension spring, one end of each second tension spring is connected to an active rotating arm, and the other end is connected to a mounting beam of the stop mechanism.

[0024] As an optimal technical solution, the top of each active rotating arm is equipped with a first rotating shaft parallel to the rotating rod, and the two ends of the first rotating shaft are equipped with first rotating wheels, and the top surface of the first rotating wheel is higher than the top surface of the active rotating arm.

[0025] As an optimal technical solution, the top of each stop arm is fitted with a second rotating shaft parallel to the rotating rod, both ends of the second rotating shaft are fitted with second rotating wheels, and the top surface of the second rotating wheel is higher than the top surface of the stop arm.

[0026] As an optimal technical solution, a coupling is provided on the rotating rod.

[0027] As a preferred technical solution, the contact surface between the stop block and the stop arm is an arc surface.

[0028] As a preferred technical solution, each lifting platform is connected to a lifting mechanism provided on the frame;

[0029] Each lifting platform is provided with two guide frame transverse moving rails and a guide frame driving motor. A guide frame is provided on the two guide frame transverse moving rails, and the guide frame is connected to the guide frame driving motor. The electric vehicle pallet moving rail includes two electric vehicle pallet conveying rails. An electric vehicle pallet conveying rail is provided on each side of the guide frame transverse moving rail on the lifting platform.

[0030] As a preferred technical solution, the pallet movement drive device includes several gears; a group of gears arranged horizontally on the leading frame, a group of back pressure wheels arranged horizontally, and the gear closest to the frame is connected to the gear drive motor provided on the leading frame; a rack is provided horizontally at the bottom end of the electric vehicle pallet; and a plurality of rolling wheels are provided on the bottom surface of the electric vehicle pallet that can move on each electric vehicle pallet conveyor rail;

[0031] When both ends of the pallet are respectively located on the electric vehicle pallet conveyor rails, the toothed surface of the rack engages with the gears, and the toothless surface of the rack is combined with the back pressure wheels; when the bottom surface of the leading frame on the lifting platform controlled by the lifting mechanism is flush with the top surface of the stop mechanism mounting beam close to a charging position on the lifting platform side, each active rotating arm is located between the front side and the rear side of the leading frame.

[0032] The toothed side of the rack meshes with the gears, while the untoothed side of the rack engages with the back-pressure rollers. This rotation of the gears allows the rack to drive the pallet's lateral movement. The pilot frame can move laterally into the charging station's charging bays, where the gears and racks work together to deliver the pallet to the charging bays. Alternatively, the racks engage with the racks of the pallets in the charging bays, working in conjunction with the pilot frame to deliver the pallet to the lift. A set of back-pressure rollers ensures stable lateral movement of the pallets during transport.

[0033] When the vehicle on the electric vehicle pallet is charging, the leading frame enters the charging position from the lifting platform and contacts the active rotating arm in the charging position, causing it to rotate so that the active rotating arms and the stop mechanism located in the charging position are installed below the top surface of the beam. The pallet lateral movement device drives the electric vehicle pallet from the electric vehicle pallet inlet and outlet into the charging position. The leading frame completely sends the electric vehicle pallet into the charging position and the leading frame returns to the lifting platform. At this time, each stop arm contacts the stop block of the electric vehicle pallet under the action of the spring return assembly, stabilizing the electric vehicle pallet in the charging position.

[0034] After charging is complete, the pilot frame on the platform enters a charging position on the side of the frame body closest to the platform. The pilot frame contacts the stop arms in the charging position, causing them to rotate so that each stop arm is located below the stop block in the charging position. The pilot frame then moves the electric vehicle tray out of the charging position and returns it to the platform. The stop arms are reset by the spring return assembly. The lifting mechanism controls the platform to descend to the ground, and the vehicle is driven out of the electric vehicle tray on the pilot frame of the platform.

[0035] As an optimal technical solution, the top and bottom ends of each leader frame's transverse moving track are connected to a number of pressure wheels arranged longitudinally along the central axis and protruding toward the direction of the other leader frame's transverse moving track. The pressure wheels at the top end of each leader frame's transverse moving track are in contact with the top surface of the leader frame, and the pressure wheels at the bottom end of each leader frame's transverse moving track are in contact with the bottom surface of the leader frame.

[0036] As an optimal technical solution, two drive chain support wheels are longitudinally provided at the bottom end of the horizontal moving track of one of the leading frames, and the two drive chain support wheels are connected to the drive chain. One of the drive chain support wheels is connected to the leading frame drive motor, and the drive chain is connected to the bottom surface of the leading frame.

[0037] As a preferred technical solution, the gear closest to the frame is connected to the driving wheel of the gear drive motor through a transmission chain.

[0038] As an optimal technical solution, a charging position horizontal pallet rack moving guide rail is provided below the front and rear ends of the charging position on the frame. When the lifting mechanism controls the bottom surface of the guide frame on the lifting platform to be flush with the top surface of the stop mechanism mounting beam of a charging position close to the lifting platform side of the frame, the moving guide rail of each charging position horizontal pallet rack is aligned with the electric vehicle pallet conveyor rail closest to it.

[0039] As an optimal technical solution, the lifting mechanism includes a lifting motor located at the top of the frame, each lifting platform is connected by a lifting chain, and the lifting motor is externally connected to a power supply.

[0040] As an optimal technical solution, a female charging docking assembly mounting rod is longitudinally provided below each charging position on the frame away from the inlet and outlet ends of the electric vehicle tray. A female charging docking assembly is installed on the female charging docking assembly mounting rod, and a sub-charging docking assembly is installed on the side of each electric vehicle tray close to the female charging docking assembly mounting rod; when the electric vehicle tray fully enters a charging position, the sub-charging docking assembly on the electric vehicle tray docks with the female charging docking assembly closest to it; each female charging docking assembly is externally connected to a charging stack.

[0078] A plurality of stop blocks 60 are provided on the bottom surface of the electric vehicle tray 6, and the electric vehicle tray 6 is located in the charging position 13 or on the electric vehicle tray moving track; when the electric vehicle tray 6 is located in the charging position 13, each stop arm 32 contacts a stop block 60; when the bottom surface of the leading frame 52 of the lifting platform 5 is flush with the top surface of a stop mechanism mounting beam 11, each active rotating arm 31 on the rotating rod 3 connected to the stop mechanism mounting beam 11 is located between the front side and the rear side of the leading frame 52.

[0079] When parking the car, the driving guide frame 52 on the lifting platform 5 first enters the charging position 13, pushes each active rotating arm 31 laterally, drives the rotating rod 3 to rotate, so that the top end of the stop arm 32 is located below the stop block on the bottom surface of the electric vehicle tray 6; the tray moving drive device drives the electric vehicle tray 6 to enter the charging position 13; the driving guide frame 52 on the lifting platform 5 is reset, and under the action of the spring reset component, the end of each stop arm 32 is in close contact with the stop block 60 on the bottom surface of the electric vehicle tray 6.

[0080] When picking up the car, the driving guide frame 52 on the lifting platform 5 first enters the charging position 13, pushes each active rotating arm 31 laterally, drives the rotating rod 3 to rotate, so that the top of each stop arm 32 is located below the stop block on the bottom surface of the electric vehicle tray 6; the tray moving drive device drives the electric vehicle tray 6 to leave the charging position 13; the driving guide frame 52 on the lifting platform 5 is reset, and each stop arm 32 and the active rotating arm 31 are reset.

[0082] Each lifting platform 5 is connected to a lifting mechanism mounted on the frame 1. The lifting mechanism includes a lifting motor 4 located at the top of the frame. The lifting platform is connected to the lifting motor 4 via a lifting chain 41, which is connected to an external power source. A lifting shaft 42 and a lifting motor 4 are longitudinally disposed at the top of the frame. Each lifting shaft 42 is connected to the lifting motor 4. Each lifting shaft 42 is provided at each end with a lifting wheel 43, each of which is connected to a lifting chain 41. Each lifting platform 5 is connected to a lifting chain 41 at each end.

[0083] Each lifting platform 5 is provided with two guide frame transverse moving rails 51 and a guide frame driving motor 53. The two guide frame transverse moving rails 51 are provided with a guide frame 52, and the guide frame 52 is connected to the guide frame driving motor 53; the electric vehicle pallet moving rail includes two electric vehicle pallet conveying rails 54; an electric vehicle pallet conveying rail 54 is provided laterally on each side of the guide frame transverse moving rail 51 on the lifting platform 5.

[0084] The pallet movement drive mechanism includes several gears 55; a set of gears 55 and a set of back pressure rollers 56 arranged transversely on the leading frame 52. The gears 55 closest to the frame body 1 are connected to a gear drive motor 57 mounted on the leading frame 52. A rack 61 is positioned transversely at the bottom end of the electric vehicle pallet 6; and several rolling wheels 62 are positioned on the bottom surface of the electric vehicle pallet 6, enabling movement along the respective electric vehicle pallet conveyor rails 54. There are three gears 55 and three back pressure rollers 56. The leading frame 52 is provided with three panels 513, each equipped with a gear 55 and a back pressure roller 56.

[0085] When the two ends of the pallet 6 are respectively located on the electric vehicle pallet conveying rails 54, the toothed surface of the rack 61 engages with each gear 55, and the toothless surface of the rack 61 is combined with each back pressure wheel 56; when the bottom surface of the leading frame 52 on the lifting platform 5 controlled by the lifting mechanism is flush with the top surface of the stop mechanism mounting beam 11 of the frame 1 close to a charging position 13 on the side of the lifting platform 5, each active rotating arm 31 is located between the front side and the rear side of the leading frame 52.

[0086] The top and bottom ends of each leading frame transverse moving track 51 are respectively connected with three pressure wheels 58 arranged longitudinally along the central axis and protruding toward the other leading frame transverse moving track 51. The pressure wheels 58 at the top end of each leading frame transverse moving track 51 are in contact with the top surface of the leading frame 52, and the pressure wheels 58 at the bottom end of each leading frame transverse moving track 51 are in contact with the bottom surface of the leading frame 52.

The tray transverse moving device drives the electric vehicle tray 6 from the electric vehicle tray inlet and outlet 14 into the charging position 13. The leading frame 52 completely sends the electric vehicle tray 6 into the charging position 13 and the leading frame 52 returns to the lifting platform 5. At this time, each stop arm 32 contacts the stop block 60 of the electric vehicle tray 6 under the action of the spring return assembly, stabilizing the electric vehicle tray 6 in the charging position 13.

[0093] After charging is complete, the leading frame 52 on the lift platform 5 enters a charging position 13 on the side of the frame 1 closest to the lift platform 5. The leading frame 52 contacts the stop arms 32 in the charging position 13, causing it to rotate so that each stop arm 32 is located below the stop block 60 in the charging position 13. The leading frame 52 removes the electric vehicle tray 6 from the charging position 13 and returns it to the lift platform 5. The stop arms 32 are reset by the spring return assembly. The lifting mechanism controls the lift platform 5 to descend to the ground, and the vehicle exits the electric vehicle tray 6 on the leading frame 52 of the lift platform 5.

A second rotation axis 38, parallel to the rotation rod 3, is mounted on the top of each stop arm 32. Second rotating wheels 39 are mounted on both ends of the second rotation axis 38. The top surface of the second rotating wheel 39 is higher than the top surface of the stop arm 32.
