[0024] In some embodiments, special fire protection measures are required for charging in high-rise parking spaces. The high-rise fire protection measures include fire isolation devices, fire extinguishing devices, and fall arrest devices.

[0025] The fire isolation device includes a fire isolation track, a long top beam, a short top beam, a long fire isolation wall, a short fire isolation wall, a top fire isolation board, a slider, a lifting ring, an electromagnetic hook, and a winch. Four pairs of fire isolation tracks made of channel steel are vertically installed at the four corners of the parking rack. The length is equal to the height of the front and rear columns of the parking rack. The lower end of the fire isolation track starts from the second floor upwards. The long top beam connects the top of the fire isolation track on the same side of the long side, and the short top beam connects the top of the fire isolation track on the same side of the end side. Therefore, the maximum height of the track is higher than the height of one parking space at the top of the parking rack. The long fire isolation wall and the short fire isolation wall are placed vertically and are respectively used at the front and rear sides and the left and right ends of the parking space, and both sides of the fire isolation wall are vertically installed at least Two sliders are embedded in the grooves of the fire isolation tracks at the corresponding ends and can slide up and down. Four winches are installed in the middle of the two long top beams and the two short top beams respectively. The electromagnetic hook is hung on the tail end of the wire rope of the winch. A lifting ring is installed in the middle of each long fire wall and short fire wall, which serves as the hanging ring of the electromagnetic hook. By hooking each lifting ring, each fire isolation wall panel can be lifted to the top floor. Normally, all fire isolation wall panels are lifted to the highest point by the winch. Once a fire occurs, the electromagnetic hook will open the hook at the first time, and all fire isolation wall panels at the highest point will be released and fall down along the fire isolation track. The top fire isolation board is installed above the power supply robot on each floor, covering the entire top plane of the parking space.

[0026] The anti-fall device includes an anti-fall support, an anti-fall square tube, an anti-fall electric push rod, and a sliding square tube sleeve. The vertical plate at one end of the anti-fall support is installed with the anti-fall electric push rod, and the horizontal plate at the other end is welded with a linear sliding square tube sleeve. The anti-fall square tube is inserted into the sleeve and connected to the sliding rod of the anti-fall electric push rod. When the anti-fall electric push rod is extended, the other end of the anti-fall square tube cantilever extends out of the sliding square tube sleeve. When the anti-fall electric push rod is retracted, the other end of the anti-fall square tube cantilever retracts into the sliding square tube sleeve, and the end faces are basically flush. The front beams, rear beams and both ends of the front and rear sides of each parking space are At least two anti-fall devices are installed horizontally in the middle section of the first track end beam, and the anti-fall square tubes are cantilevered outward. When all the anti-fall square tubes on the same level of the parking space are extended out of the sliding square tube sleeve, the extended cantilever section can prevent the two sides of the parking space on this level and the long fire walls and short fire walls on both sides from continuing to fall. Together with the upper and lower top fire barriers of the parking space, the parking space is enclosed by the fire barriers, which can separate the charging vehicles that may catch fire in the parking space from the vehicles and equipment stored in other stereo garages to prevent the spread of fire.

[0027] The fire extinguishing device includes a launching spring, a launching pipe, a launching trigger, a trigger rod, a trigger cross-link, and a fire extinguishing ball. The long fire wall and the short fire wall have a hollow structure, and the fire extinguishing device is installed vertically side by side. The launching pipe is placed vertically, the upper section has an arc section, the lower straight section has a long slot, and the upper end is open and the bottom end is closed. The launching spring is installed in the straight lower section of the launching pipe, and the launching trigger is installed outside the long slot of the straight lower section of the launching pipe. The upper hook of the launching trigger passes through the long slot and hooks the upper edge of the compressed launching spring. The lower hook of the launching trigger is supported by the trigger rod passing through the bottom plate of the fire wall. A number of fire extinguishing balls are installed in the upper section of the launching pipe. Once they hit the lower end of the trigger rod, the hook on the trigger trigger is deflected outward, releasing the compressed launching spring, so that the launching spring can rapidly push the upper When a vehicle in a high-rise parking space catches fire, the anti-fall electric push rod of the top fire extinguishing device will be retracted immediately. At the same time, the anti-fall electric push rods of all the fire extinguishing devices on the vehicle fire floor will be extended immediately. Therefore, the four fire-isolating wall panels originally on the top floor will fall vertically along the fire-isolating track, but will be blocked by all the anti-fall square tubes extended on the fire floor. When they are caught, the anti-fall square tubes hit the triggering horizontal connecting rod, causing all the fire-extinguishing balls in the fire-isolating wall panels around the fire floor to be rapidly ejected and thrown to the position where vehicles in the parking space are more likely to catch fire until the fire is extinguished.

[0028] According to the properties of the vehicle's burning material, the shell of the fire extinguishing ball is made of a material or structure that can be cracked by projection or easily dissolved at high temperature, and the fire extinguishing material inside it is made of different materials according to the properties of the vehicle's burning material, such as water, fire extinguishing foam or yellow sand.

[0060] The present invention will be further described in detail below with reference to the accompanying drawings.

[0061] like Figure 1 、 Figure 2 、 Figure 3 As shown, a stereoscopic parking garage with an automatic charging system includes: a garage body 1, a carrier 2, and an automatic charging system 3. The garage body 1 is a multi-layer structure in the vertical direction, with each layer having parking spaces. The garage body 1 includes a parking rack 10, a loading plate 20, a side shift device 30, a lifting device 50, a temporary parking frame 01, an intelligent control system 02, and an anti-fall guardrail 03.

[0062] The parking rack 10 includes an upright truss 11, a front crossbeam 12, and a rear crossbeam 13. The upright truss 11 is a rectangular truss composed of a front column 111, a rear column 112, and a first track end beam 113. The front column 111 and the first track end beam 113 are made of channel steel, and the grooves on both sides can be used as roller tracks. Multiple upright trusses 11 are erected at a certain distance from each other, and the front and rear crossbeams 12 and the rear crossbeams 13 are used to connect the adjacent two pieces horizontally to form a multi-layer matrix-type three-dimensional frame. Each unit is a parking space. The connection of the front crossbeam 12 cannot block the tracks on both sides of the front column 111. It is connected below the first track end beam 113. The front crossbeam 12 is no longer provided in the first parking space. The garage main body 1 can store the parking rack 10 in a single row or in parallel into multiple rows. The two adjacent rows of storage racks 10 can share a vertical truss 11 between them. The beneficial effects are: simple structure, easy installation, and reduced equipment cost.

[0063] like Figure 4 、 Figure 5 As shown, the vehicle loading plate 20 includes a vehicle loading main beam 21, a first roller 22, a wheel support plate 23, and a second roller 24. The vehicle loading main beam 21 is mainly a rectangular steel pipe with a roller shaft symmetrically welded at each end. The two first rollers 22 are symmetrically installed with the roller shafts, and the center lines of the rollers are horizontally straight lines. The first rollers 22 on both sides are arranged in the groove tracks of the first track end beams 113 of the vertical trusses 11 at both ends of each storage area in the storage rack 10, and roll horizontally along the tracks. The center distance between the two wheel support plates 23 is corresponding to the front and rear wheel wheelbases of the vehicle, and they are connected to the front side of the vehicle loading main beam 21 in a cantilever manner. The lower surface of the load-bearing side beams on both sides of each wheel support plate 23 is horizontally supported on the four second rollers 24 installed on the front cross beam 12. Therefore, the vehicle loading plate 20, supported by the second rollers 24 and the first rollers 22, can be cantilevered in and out in a horizontal rolling manner.

[0064] like Figure 6 、 Figure 7 As shown, the side shift device 30 includes a side shift motor 31, a transmission shaft 32, a support bearing 33, a first electromagnetic clutch 34, a first driving sprocket 35, a first driven sprocket 36, a first traction chain 37, and a traction rod 38. The side shift motor 31 is installed at the center of the rear cross beam 13 on the top of the storage rack 10, and is connected to the vertically placed transmission shaft 32 downward through a coupling. Each layer of the transmission shaft 32 is keyed to a first electromagnetic clutch 34 with a first driving sprocket 35 installed in the outer shell. At the same time, a support bearing 33 is installed on the rear cross beam 13 of each layer. The first driven sprocket 36 is installed in the center of the front cross beam 12 and is in the same horizontal line as the first driving sprocket 35. The first traction chain 37 is divided into a plurality of sections. The first traction chain 37 is connected to the traction rod 38 at both ends. The traction rod 38 has bolts for adjusting the tightness of the first traction chain 37. Then, the traction rod 38 is installed at the center line position below the main beam 21 of the vehicle loading plate 20, that is, the center line of the first traction chain 37 on the side containing the traction rod 38 should coincide with the vehicle loading plate 20. Therefore, through the rotation of the first driving sprocket 35, the first traction chain 37 can pull the vehicle loading plate 20 horizontally. If a certain layer of vehicle loading plate 20 needs to be driven, it is only necessary to connect the first electromagnetic clutch 34 of that layer. Therefore, no matter how many layers of parking spaces there are in the parking rack 10, only one side shift motor 31 is needed, which greatly reduces the equipment cost.

[0065] The lifting device 50 includes an electric winch 51, a steel wire rope 52, a movable pulley 53, a lifting frame 54, and a third roller 55. The lifting frame 54 is composed of a lifting main beam 541, a bent vertical plate 542, a lifting channel steel 543, and a central base 544. The two ends of the lifting main beam 541 are vertically and symmetrically welded with a bent vertical plate 542. The central base 544 is welded to the vertical center line on the front side. The welding openings are opposite to the two lifting channel steels 543 at a certain horizontal distance from the vertical center line. The two movable pulleys 53 are symmetrically installed on the front side of the lifting main beam 541. 51 is horizontally installed at the top of the front column 111 of the storage rack 10. The two ends of the wire rope 52 pass through the two movable pulleys 53 and are vertically upward. One end is connected to the electric winch 51, and the other end is fixed to the top of the front column 111 on the other side. Two third rollers 55 are symmetrically installed on the outside of the two bent vertical plates 542. The centers of the two third rollers 55 on each side are in a vertical line and are respectively set in the grooves of the front columns 111 on both sides. When the electric winch 51 is started, the lifting frame 54 can be horizontally lifted and moved vertically along the grooves of the front columns 111 by winding the wire rope 52.

[0066] The temporary parking frame 01 is a white painted rectangular line drawn on the ground outside the lateral parking rack 10. Its plane size is slightly larger than the plane projection size of the vehicle. Two horizontal front wheel stop lines 013 are drawn in the rectangular dotted line frame 012. This is the parking frame for vehicles parked in the second-floor parking space. The parked vehicle must first be parked in the rectangular dotted line frame 012, and the front wheels of the vehicle must also stop within the two stop lines 013. The projection of any part of the vehicle on the ground must not exceed the temporary parking frame 01, otherwise the transporter 1 will not move.

[0067] The intelligent control system 02 includes: an electric control box 021, a parking position recognition device 022, an operating panel 023, an automatic control device 024, a fault alarm device 025 and other conventional electrical components. The electric control box 021 is installed on the front pillar 111 of the parking rack 10 at a position convenient for the driver to operate. The operating panel device 023, the automatic control device 024, and the fault alarm device 025 are all installed on the electric control box 021. The parking position recognition device 022 is installed on the wire frame of the temporary parking frame 01. When the driver operates the operating panel device 023, the parking position recognition device 022 can emit wireless rays to detect whether the vehicle parts parked in the temporary parking frame 01 are beyond the frame.

[0068] The beneficial effects of the present invention are: making the equipment manufacturing and installation simpler, and making more efficient use of parking lot space. Parking in and out of the garage is all on the ground of the vehicle driving passage, and there is no need to drive into a sloped and narrow special loading platform. The parking and retrieval of the vehicle is intelligent, automatic, and fast, and all operations are completed on the electrical control box panel.

[0069] like Figure 8 、 Figure 9 、 Figure 10As shown, the transporter 2 includes a vehicle picker 40. The "vehicle picker" mentioned here is a device used for vehicle transport operations in a three-dimensional parking garage, which is used to perform sideways "fork picking" of static and unmoving vehicles, especially an operating tool for "forking" the vehicle chassis.

[0070] The first embodiment is an overlapping rotary vehicle pickup device 40, which includes a carriage assembly 41, a first fork assembly 42, a second fork assembly 43, a one-way bending chain 44, a bearing support 45, a plane bearing 46, a bearing ring 47, a transverse locking pin shaft 48, a fork sleeve 49, a fork cylinder 401, and a hydraulic power unit 402.

[0071] The carriage assembly 41 includes a carriage 411, a third roller 412, and a cylinder rear seat 414. The carriage 411 is a structural frame welded together by a horizontal plate 415, two vertical plates 416, and two chain support plates 417. Relative to the vertical centerline of the carriage 411, two bearing supports 45 are symmetrically mounted on the front side of the horizontal plate 415. Four third rollers 412 are symmetrically mounted on the outside of the two vertical plates 416, and the third rollers 412 are placed in the lifting channel steel 543. The carriage 411 and the hydraulic power unit 402 are fixedly mounted on the lifting frame 54. The hydraulic power unit 402 is an integrated component composed of a motor, an oil pump, a valve, and an oil tank. The rear seat 414 of the oil cylinder is installed behind the horizontal plate 415. The first fork assembly 42 includes a first fork body 421, a column pin shaft 422, and a first lever 423. The fork body 421 is an L-shaped right-angled member. Its vertical section is a relatively short round steel cylinder. There is a horizontal horizontal hole on the upper end of the steel cylinder. The bearing support 45 on one side of the slide 411 is inserted from the bottom to the top. Then, the upper end is successively covered with a plane bearing 46 and a bearing ring 47. Then, the horizontal locking pin shaft 48 is used to insert the horizontal locking pin 48 into the horizontal locking pin 48. The load ring 47 is fixed to the upper end of the steel column. The fork body 421 is a horizontal section of rectangular cross-section steel. There is a groove on the vertical surface outside the root of the horizontal section. The groove is embedded with a one-way bending chain 44. The cantilever end of the horizontal section is inserted into the fork sleeve 49. The end of the vertical surface outside the inserted end is connected to one end of the one-way bending chain 44. The other end of the one-way bending chain 44 is connected to the chain support plate 417 on this side. The first shift rod 423 is horizontally installed on the rear side of the right-angle root of the first fork body 421. The fork cylinder 401 is placed horizontally and is hinged at one end through the column pin shaft 422. The cantilever end of the first shifting rod 423 is hingedly connected to the cylinder rear seat 414 on the rear side of the horizontal plate 415 at the other end. Through the telescopic movement of the articulated fork cylinder 401, the first fork body 421 can be pushed to rotate horizontally 90 degrees. At the same time, due to the unidirectional bending performance of the unidirectional bending chain 44, during the rotation of the first fork body 421, the fork sleeve 49 telescopically slides linearly along the horizontal section of the first fork body 421. When the horizontal section is parallel to the horizontal plate 415, the fork sleeve 49 retracts the most. When the horizontal section is perpendicular to the horizontal plate 415 at 90 degrees, the fork sleeve 49 extends the most.The second fork assembly 43 includes a second fork body 431, a ball pin 432, a second lever 423, a high-position spring 435, and a sliding support 436. The second fork body 431 is also an L-shaped right-angled component. The vertical section is a relatively long round steel cylinder. The rest is the same as the first fork body 421. It is inserted from the bottom to the top into the bearing support 45 on the other side of the slide 411. Then, the upper end is successively covered with a plane bearing 46, a spring 435, and finally a bearing ring 47. The second lever 433 is horizontally installed on the rear side of the right-angle root of the first fork body 421. The rest of the assembly is the same as the first fork assembly 42, except that the other end of the one-way bending chain 44 is The fork oil cylinder 401 is basically placed horizontally, and is connected to the cantilever end of the second shift rod 433 through the ball pin 432 at one end, and is connected to the cylinder rear seat 414 on the other side of the rear of the horizontal plate 415 at the other end through the ball joint oil cylinder 424. The ball joint oil cylinder 424 is telescopically movable to push the first fork body 421 to rotate horizontally 90 degrees. At the same time, due to the unidirectional bending performance of the unidirectional bending chain 44, during the rotation of the first fork body 421, the fork sleeve 49 makes a linear telescopic sliding along the horizontal section of the first fork body 421. Because the articulated fork oil cylinder 401 is connected to the ball joint oil cylinder 424, the fork sleeve 49 makes a linear telescopic sliding along the horizontal section of the first fork body 421. The cylinder 401 is installed in a mirror-symmetrical manner. Therefore, for the extension and retraction movement of the oil cylinder, the rotational movement directions of the first fork assembly 42 and the second fork assembly 43 are opposite. At the same time, since a high-position spring 435 is installed on the upper end of the vertical cylinder of the second fork assembly 43, when there is no load, the second fork body 431 is lifted by the spring 435. The height of the raised horizontal section is slightly greater than the thickness of the fork sleeve 49. Therefore, the horizontal section of the second fork assembly 43 will be higher than the horizontal section of the first fork assembly 42. When the horizontal sections of the first fork assembly 42 and the second fork assembly 43 are parallel to the horizontal plate 415, the upper and lower spaces of the two overlap. When both are unloaded, they can be rotated 90 degrees in opposite directions to form a forked state. Once the two are ready to fork the vehicle chassis and the slide is raised, the horizontal section fork sleeve 49 of the second fork assembly 43 will first encounter the load force, which is greater than the pressure of the spring 435. Then the horizontal section fork sleeve 49 of the second fork assembly 43 will not be lifted until the horizontal section fork sleeve 49 of the first fork assembly 42 encounters the load force. Then the two will fork together in the vehicle horizontal state and perform a lifting movement. Of course, once the fork is unloaded, the second fork body 431 will automatically rise again under the operation of the spring 435, and the fork will retract at the same time. There will be no movement interference between the horizontal sections.

[0072] The temporary parking frame 01 is drawn on the ground outside the front of the parking rack 10 to indicate the driver's accurate parking range before the vehicle enters the garage. Its outer frame is a rectangular dotted frame 012, whose plane size is slightly larger than the plane projection size of the vehicle. Two horizontal front wheel stop lines 013 are drawn in the frame. The vehicle to be stored must first be parked within the rectangular dotted frame 012, and the front wheels of the vehicle must also be pressed within the range of the two stop lines 013 so that the forks of the vehicle picker 40 can accurately align with the vehicle chassis support point. The projection of any part of the vehicle on the ground must not exceed the temporary parking frame 01, otherwise the transporter 1 will not move, avoiding collisions between vehicle parts and garage parts during the vehicle entry operation.

[0073] The advantages of the overlapping rotary car picker 40 are: the fork structure is simple and firm, the oil cylinders can move at the same time, and the speed is fast.

[0074] like Figure 11 、 Figure 12 As shown, the carrier 2 may further include a lifting mechanism 60, which includes a lifting cylinder 61, a guide wheel assembly 62, a lifting chain 63, and a chain joint 64. The lifting cylinder 61 adopts a single-acting plunger cylinder, the bottom of the cylinder barrel is seated on the central base 544 of the lifting frame 54, and the top of the plunger rod is installed with a guide wheel assembly 62. Both ends of the lifting chain 63 are connected to the chain joint 64, passing around the guide wheel on the guide wheel assembly 62. One chain joint 64 is connected to the hanging chain plate on the cylinder barrel, and the other end goes to the horizontal plate 41 on the slide 411 in the vehicle pick-up device 40. 5 is connected to the lower side of the rear part, and the third roller 412 on the slide 411 is placed in the lifting channel steel 543 and rolls vertically along the lifting channel steel 543. The hydraulic power unit 402 is composed of a motor, an oil pump, a valve, and an oil tank as an integrated component, which respectively provides power hydraulic oil to the lifting cylinder 61 and the articulated fork cylinder 401 on the vehicle picker 40. When the hydraulic power unit 402 is started and pressure oil is supplied to the lifting cylinder 61, the slide assembly 41 can move vertically along the groove track of the lifting channel steel 543 with the first fork assembly 42 and the second fork assembly 43.

[0075] After adding the lifting mechanism 60, its beneficial effects are: first, the lifting main beam 541 of the lifting frame 54 does not need to stop at a height higher than the vehicle loading plate 20 when it rises; second, before the vehicle loading plate 20 moves laterally with the vehicle, there is no need to first retract the fork of the vehicle picker 40, and then lift the lifting frame 54 and the vehicle picker 40 to a height higher than the vehicle before moving laterally. Instead, the lifting frame 54 can be directly lifted and moved. As long as the top of the lifting channel steel 544 on the lifting frame 54 is lower than the vehicle chassis, the vehicle loading plate 20 can start to move laterally with the vehicle; and, when the lifting frame 54 starts to descend, that is, in the process of returning to the initial state, the vehicle picker 40 and the lifting mechanism 60 can be driven simultaneously and both return to the initial state, thereby saving a lot of time for the reciprocating up and down movement of the lifting device 30. The beneficial effect is that the lifting mechanism 60 can be used to lift the carriage assembly 41 to a relatively small height, so that the front and rear tires of the vehicle are lifted to a height higher than the height of the crossbeam of the lifting frame 54. Then, the side shifting device 30 can push the vehicle loading plate 20 to be inserted under the vehicle tires to receive the vehicle. The lifting device 50 does not need to lift the lifting frame 54 to a position higher than one level before moving the vehicle loading plate 20, except for vehicles entering or exiting the next level. This saves time and improves the speed of parking and retrieving vehicles.

[0076] like Figure 13 、 Figure 14 、 Figure 15 As shown, the automatic charging system 3 includes a power supply device 80, a charging socket 90, and an automatic charging control 100. The power supply device 80 includes: a charger 81, a power plug 83, a conical charging plug 84, a retractable cable 85, and a first robot 86.

[0077] like Figures 19 to 22 As shown, the conical charging plug 84 includes a charging plug shell 841, a conductive contact pin 842, a pressure spring 843, a locking screw 844, an insulating spring seat 845, and a plug cover 846. The conductive contact pin 842 is made of a material with good conductive properties and is formed into a stepped cylinder. The lower end is a contact surface, and the upper end is a threaded hole. The locking screw 844 is screwed into the hole to connect the cable. The charging plug shell 841, made of insulating material, has a guiding conical cylinder shape. The interior has several concentric circular planes of different diameters. Each circular ring has at least two stepped vertical holes. At least two conductive contact pins 842 and a pressure spring 843 are inserted into each hole in the circular ring. Then, the insulating spring seat 845 is put on, and the several conductive contact pins 842 are mounted on the charging plug shell 841 so that they can move up and down slightly. After the upper ends of the conductive contact pins 842 are connected to the corresponding conductive wires, the plug cover 846 made of insulating material is covered and connected to the charging plug shell 841 to form a waterproof insulator.

[0078] The first robot 86 adopts a rectangular coordinate system XYZ three-dimensional motion structure, including a transverse movement mechanism 87, a longitudinal movement mechanism 88, and a plug-in mechanism 89. The transverse movement mechanism 87 includes a charging track beam 871, a moving main beam 872, a fifth roller 873, a second electromagnetic clutch 874, a second driving sprocket 875, a second driven sprocket 876, and a second traction chain 877. The charging track beam 871 can be made of "H"-shaped steel, which is welded in parallel under each first track end beam 113 of the storage rack 10. The moving main beam 872 is a rectangular frame welded by two long channel steels and two short vertical steel plates. The frame is horizontally arranged, and two second short vertical steel plates are symmetrically installed horizontally on both sides. The fifth roller 873 at both ends is placed in the groove of the charging track beam 871 on both sides. At this time, the mobile main beam 872 is in the top space of the parking space. The second electromagnetic clutch 874, the second driving sprocket 875, the second driven sprocket 876, the second traction chain 877 and the first electromagnetic clutch 34, the first driving sprocket 35, the first driven sprocket 36, and the first traction chain 37 are assembled in the same way and are horizontally installed under the corresponding accessories. Moreover, the two ends of the second traction chain 877 are connected in the middle of the two long channel steels of the mobile main beam 872. Therefore, when the side shift motor 31 is running, the second electromagnetic clutch 874 is energized, and the second driving sprocket 87 5 rotates, which will pull the moving main beam 872 to move horizontally along the groove track of the charging track beam 871 in the top space of the parking space. The longitudinal movement mechanism 88 includes a trolley frame 881, a sixth roller 882, and a charging screw machine 883. The trolley frame 881 is a rectangular frame welded with steel plates. The trolley frame 881 is horizontally arranged, and two sixth rollers 882 are symmetrically installed on both sides of the long side. The sixth rollers 882 on both sides are placed in the two long channel steels of the moving main beam 872. The horizontally placed charging screw machine 883 base is installed on the moving main beam 872, and the movable nut is in the middle of the short side of the trolley frame 881. Therefore, starting the charging screw machine 883 can drive the trolley frame 881 to move along the moving main beam 87 2 makes longitudinal movement in the space above the parking space. The plug-in / plug-out mechanism 89 includes an electric push rod 891 and a flexible ball joint 892. The fixed part of the electric push rod 891 is vertically installed in the center of the trolley frame 881. The flexible ball joint 892 is located at the lower end of the movable push rod. Under the action of the electric push rod 891, the first robot 86 can make vertical movement up and down in the space above the parking space. Therefore, the function of the first robot 86 is to provide XYZ movement function in the space above the parking space. The conical charging plug 84 is installed at the lower end of the flexible connector 892. The function of the flexible connector 892 is to allow the center line of the conical charging plug 84 to deflect 360° in space at a small angle to accommodate the possible non-strict horizontal state of the corresponding socket.

[0079] The charger 81 can be fixed and mounted on the storage rack 10 , which is suitable for a slow charger. Therefore, the conductive connection is: power supply plug 83 —fixed cable —slow charger 200 —retractable cable 85 —conductive contact pin 842 of the conical charging plug 84 .

[0080] In the case where the charger 81 is a fast charger, it is suitable for installation on the small vehicle frame 881 so that the cable transmitting high current is as short as possible. The conductive connection is: power supply plug 83--retractable cable 85--fast charger 200--flexible cable--conductive contact pin 842 of the conical charging plug 84.

[0081] The charging socket 90 includes: a conical socket 91, an intermediate connection line 92, a vehicle charging plug 93, and a suction cup device 94. The conical socket 91 includes: a charging socket shell 911 that matches the conical charging plug 84, a plurality of conductive rings 912 of different diameters, a plurality of terminal posts 913, a plurality of terminal screws 914, a socket base 915, and a socket cover 916. The charging socket shell 911 is made of insulating material, and the upper end is an inner conical guide mouth, and the inner bottom is a surface with multiple concentric circular grooves, each circular groove has at least one vertical hole, and the lower circumferential surface of the conductive ring 912 is at least connected to the inner conical guide mouth. Connect a terminal 913, and then embed it into the concentric ring groove on the charging socket shell 911 of the same diameter, forming a plane insulated from each concentric conductive ring 912. After each terminal 913 passes through the vertical hole, the lower end can be connected to the corresponding intermediate connection line 92 and the on-board charging plug 93. Finally, the charging socket shell 911 and the socket base 915 are connected to form an external waterproof insulator. The circuit of the charging socket board 90 is conductively connected: conductive ring 912--terminal 913--intermediate connection line 92--on-board charging plug 93, and finally connected to the charging socket of the vehicle.

[0082] The on-board charging plug 93 is a standard charging plug that matches the charging socket on the following vehicle. The intermediate connecting line 92 is a multi-core cable. The suction cup device 94 includes: a suction cup frame 941, a soft suction cup 942, and a manual control mechanism 943. A cone-shaped socket 91 is installed on the suction cup frame 941, and at least one soft suction cup 942 is installed below. The manual control mechanism 943 can manually control the soft suction cup 942 to enter the "sucked" state or "released" state. When the charging socket 90 is not in use, the upper port of the cone-shaped socket 91 is covered by a socket cover 916 with a bayonet or threaded seal to prevent foreign objects or dust from entering and affecting the conductive performance of the contact surface.

[0083] The charging strip 90 can be carried with the electric vehicle, stored at the entrance of the parking garage, or stored in other suitable locations within the parking garage. Its purpose and function is to allow charging sockets located at different locations on different brands of electric vehicles to be manually connected to the charging strip 90, allowing the garage's universal charging socket to be transferred to the vehicle's exterior. The present invention utilizes a suction cup device 94 to temporarily "suck and fix" the conical socket 91 to a specific location on the vehicle's roof, allowing the conical charging plug 84 installed on the first robot 86 at the top of each parking space to be automatically aligned and inserted, achieving automatic charging.

[0084] Automatic charging control 100 includes a signal transmitter 101, a signal receiver 102, an addressing controller 103, an automatic control program 104, and an electrical control box 105. Signal transmitter 101 is mounted at the center below the tapered socket 91, while signal receiver 102 is mounted at the center above the tapered charging plug 84. Addressing controller 103 and automatic control program 104 are installed inside electrical control box 105, near the power cord and in a location convenient for commissioning and maintenance.

[0085] like Figure 20 、 Figure 21As shown, the addressing robot adopts a polar coordinate system structure for three-dimensional motion and a second power supply robot, including a rotating bracket 210, a rotating mechanism 220, a rotating cantilever 230, and a plug-in mechanism 89. The rotating bracket 210 includes a central axis 211, a positioning nut 212, and a fixed bracket 213. The fixed bracket 213 is installed in the space between the front crossbeam 12 and the rear crossbeam 13 at the top of each rechargeable parking space, so that the vertically placed central axis 212 is at the top center position. The rotating mechanism 220 includes a rotating sprocket 221, a rotating disk 222, a rotating chain 223, and a third electromagnetic clutch 224. , driving sprocket 225, the third electromagnetic clutch 224 of the set driving sprocket 225 is keyed to the top of the transmission shaft 32 section of this layer, the rotating sprocket 221 is horizontally set on the central shaft 211 through a rolling bearing, and is locked by the positioning nut 212 thread, the rotating disk 222 is fixedly mounted on the rotating sprocket 221, and the rotating chain 223 respectively bypasses the driving sprocket 225 and the rotating sprocket 221 to form a rotation transmission. Therefore, when the side shift motor 31 is started and the third electromagnetic clutch 224 is energized, the driving sprocket 225 rotates and drives the rotating sprocket 221 and the rotating disk 222 to rotate through the rotating chain 223. The rotating cantilever 230 includes a seventh roller 231, a telescopic frame 232, a second electric push rod 233 and a pole support 234. The seventh rollers 231 are symmetrical in pairs at the center and are vertically mounted on the plane of the rotating disk 222 of the rotating mechanism 220. The telescopic frame 232 is a rectangular frame with a sliding track on the outside of the long side. Four groups of seventh rollers 231 are symmetrically embedded in the track on the outside of the long side of the telescopic frame 232. The pole support 234 is mounted on the edge of the rotating disk 222. The fixed sleeve end of the second electric push rod 233 is horizontally mounted on the pole support 234 and is parallel to the long side track of the telescopic frame 232. The movable rod end of the second electric push rod 233 is horizontally docked with the short side of the rectangular frame of the telescopic frame 232. Therefore, when the second electric push rod 233 is started and telescopically pushed and pulled, the telescopic frame 232 can perform horizontal linear telescopic movement supported by the four sets of seventh rollers 231. At the same time, the rotating disk 222 can rotate 360° under the drive of the rotating mechanism 220, so that the end of the short side of the telescopic frame 232 can reach any position within the area of ​​a circle with the extended length of the movable rod of the second electric push rod 233 as the radius. The plug-in mechanism 89 is vertically installed at the cantilever end of the telescopic frame 232 of the rotating cantilever 230.

[0086] The rotating mechanism 220 is installed under the central axis 211 below the rotating bracket 210, so the telescopic frame 232 of the rotating cantilever 230 is located at the top center of each parking space and can rotate, extend and retract 360° in all directions. The telescopic length of the rotating cantilever 230 is set to be approximately equal to half the longitudinal length of the top of the car. The reach of the plug-in mechanism 89 installed on the rotating cantilever 230 can cover the entire roof of the vehicle. Therefore, the conical charging plug 84 installed on the plug-in mechanism 89 can reach the "fixed adsorption" conical socket 91 of the vehicle.

[0087] like Figure 22 、 Figure 23 As shown, further, the power supply robot using the third embodiment of the rotating crank arm includes a rotating bracket 210, a rotating mechanism 220, a first arm 250, a second arm 260 and a plug-in mechanism 89;

[0088] The rotating bracket 210 includes a central shaft 211, a positioning nut 212 and a fixing bracket 213. The fixing bracket 213 is installed on the top of each rechargeable parking space so that the vertically placed central shaft 211 is at the top center position;

[0089] The rotating mechanism 220 includes a rotating sprocket 221, a rotating disk 222, a rotating chain 223, and a driving sprocket 225. The rotating sprocket 221 is mounted on the central shaft 211 via a bearing sleeve and is threadedly locked by a positioning nut 212. The rotating disk 222 is fixedly mounted on the rotating sprocket 221. The rotating chain 223 passes around the driving sprocket 225 and the rotating sprocket 221 respectively.

[0090] The first arm 250 includes a first rotating arm 251 and a second rotating motor 252. One end of the first rotating arm 251 is horizontally mounted on the rotating disk 222. The second rotating motor 252 can be a slow-speed motor and is vertically mounted on the other end of the first rotating arm 251. One end of the second arm 260 is horizontally mounted on the output shaft of the second rotating motor 252. The plug-in mechanism 89 is vertically mounted at the other cantilever end of the second arm 260.

[0091] The rotating mechanism 220 is installed under the central axis 211 below the rotating bracket 210, so that one end of the first rotating arm 251 is located at the top center of each parking space and can rotate 360° in all directions. The second arm 260 installed at the other end of the first rotating arm 251 can rotate 360° relative to the first rotating arm 251, so that the plug-in mechanism 89 cantilevered on the second arm 260 can reach a range that covers the entire roof of the vehicle. Therefore, the conical charging plug 84 installed on the plug-in mechanism 89 can reach the "fixed adsorption" conical socket 91 of the vehicle.

[0092] Since pure electric vehicles are not yet popular, an automatic charging system is not required to be installed on the top of each parking space on a parking rack 10 .

[0093] like Figures 24 to 28 As shown, for charging in high-rise parking spaces, special fire protection measures need to be added. The high-rise fire protection measures 600 include a fire isolation device 610, a fire extinguishing device 640, and a fall arrest device 630.

[0094] The fire isolation device 610 includes a fire isolation rail 611, a long top beam 612, a short top beam 613, a long fire wall 614, a short fire wall 615, a top fire isolation board 616, a slider 617, a lifting ring 618, an electromagnetic hook 619, and a winch 620. Four pairs of fire isolation rails 611 made of channel steel are vertically installed at the four corners of the storage rack 10. The length is equal to the height of the front and rear columns of the storage rack 10. The lower end of the fire isolation rail 611 starts from the second layer and goes up. The long top beam 612 extends the long side. The tops of the fire isolation rails 611 on the same side are connected, and the short top beam 613 connects the tops of the fire isolation rails 611 on the same side of the end edge, so the maximum height of the rail is higher than the height of a parking space at the top of the parking rack 10. The long fire isolation wall 614 and the short fire isolation wall 615 are placed vertically and are respectively used for the front and back sides and the left and right ends of the parking space. At least two sliders 617 are vertically installed on both sides of the fire isolation wall, and the sliders 617 are embedded in the grooves of the fire isolation rails 611 at the corresponding ends to enable the upper and lower ends to be lowered. The fire wall panels are lifted to the top by the hoist 620. The electromagnetic hook 619 will open the hook, and all the fire isolation wall panels at the highest point will be released and fall down along the fire isolation track 611. The top fire isolation board 616 is installed above the power supply robot on each floor, covering the entire top plane of the parking space. The long fire isolation wall 614, the short fire isolation wall 615, and the top fire isolation board 616 are all made of wall panels filled with fireproof material in the middle. The long fire isolation wall 614 and the short fire isolation wall 615 are thicker, and there is space in the middle to install the fire extinguishing device 640, and a fire extinguishing gap is opened on the inside.

[0095] The anti-fall device 630 includes an anti-fall support 631, an anti-fall square tube 632, an anti-fall electric push rod 633, and a sliding square tube sleeve 634. The anti-fall support 631 has a vertical plate at one end for installing the anti-fall electric push rod 633, and a horizontal plate at the other end for welding a linear sliding square tube sleeve 634. The anti-fall square tube 632 is inserted into the sleeve to connect the sliding rod of the anti-fall electric push rod 633 at one end. When the anti-fall electric push rod 633 is extended, the other end of the anti-fall square tube 632 is cantilevered out of the sliding square tube sleeve 634. When the anti-fall electric push rod 633 is retracted, the other end of the anti-fall square tube 632 is cantilevered back into the sliding square tube sleeve 634. The end faces are basically flush. At least two anti-falling devices 630 are horizontally installed on the middle sections of the crossbeam 12, the rear crossbeam 13 and the first rail end beams 113 at both ends. The anti-falling square tubes 632 are cantilevered outward, and when all the anti-falling square tubes 632 on the same floor of the parking space are extended out of the sliding square tube sleeve 634, the extended cantilever section can prevent the two sides of the parking space on this floor and the long fire walls 614 and short fire walls 615 on both sides from continuing to fall. Together with the top fire isolation boards 616 above and below the parking space, the parking space is enclosed by fire isolation boards, separating the charging vehicles that may catch fire in the parking space from the vehicles and equipment stored in other multi-story parking garages to prevent the spread of fire.

[0096] The fire extinguishing device 640 includes a projectile spring 641, a projectile pipe 642, a projectile trigger 643, a trigger rod 644, a trigger cross-link 645, a fire extinguishing ball 647, and a temperature sensor 646. The long fire wall 614 and the short fire wall 615 are hollow structures. The fire extinguishing device 640 is vertically installed side by side. The projectile pipe 642 is placed vertically, with an arc section on the upper section and a long slot on the lower straight section. The upper end is open and the bottom end is closed. The projectile spring 641 is installed in the lower straight section of the projectile pipe 642, and the projectile trigger 643 is installed outside the long slot on the lower straight section of the projectile pipe 642. The upper hook of the machine 643 passes through the long slot and hooks the upper edge of the compressed ejection spring 641. The lower hook of the ejection trigger machine 643 is supported by the trigger rod 644 that passes through the bottom plate of the fire wall panel. Several fire extinguishing balls 647 are loaded into the upper part of the ejection pipe 642. Once it hits the lower end of the trigger rod 644, the upper hook of the ejection trigger machine 643 is triggered to deflect outward, releasing the compressed ejection spring 641, so that the ejection spring 641 can rapidly push the several fire extinguishing balls 647 above along the upper arc section of the ejection pipe 642 and eject them upward and laterally. The temperature sensor 646 is installed on the conical charging plug 84 of the automatic charging system on each floor.

[0097] A number of parallel fire extinguishing devices 640 are selected to form a group, and the trigger rods 644 of the group are connected with the trigger cross-link 645. The middle and lower part of each trigger cross-link 645 corresponds to a fall-stopping square tube 632 of the fall-stopping device 630. Therefore, once a vehicle in a high-rise parking space catches fire, the temperature sensor 646 sends a signal, and the electromagnetic hook 619 will immediately open the hook, and all the fire isolation wall panels at the highest point will be released and fall downward along the fire isolation track 611. At the same time, the fall-stopping electric push rods 633 of all fire extinguishing devices 640 on the vehicle fire floor will immediately extend to prevent the vertically falling fire isolation wall panels in front, behind, left, and right from continuing to fall. At the same time, the extended fall-stopping square tubes 632 hit the trigger cross-link 645, causing all the fire extinguishing balls 647 in the surrounding fire isolation wall panels to be rapidly ejected from the injection gap on the wall and thrown to the position where vehicles in the parking space are more likely to catch fire until the fire is extinguished.

[0098] According to the properties of the vehicle's burning material, the shell of the fire extinguishing ball 647 is made of a material or structure that can be cracked by projection or easily dissolved at high temperature, and the fire extinguishing material inside it is made of different materials according to the properties of the vehicle's burning material, such as water, fire extinguishing foam, or yellow sand.

[0099] The beneficial effect is that the rechargeable automatic storage parking spaces on each upper floor or above of a three-dimensional parking garage basically share a set of surrounding fireproof walls and fire extinguishing equipment, and usually do not affect the loading and unloading of vehicles on each floor, the response speed is fast, and the fire isolation and fire extinguishing are carried out compactly, orderly and automatically.

[0100] like Figures 29 to 31 As shown, further, the cone-mouth socket can be directly fixed and installed on the vehicle roof as a window for the original roof-fixed automatic charging configuration of the electric vehicle, so as to adapt to the situation where this form of automatic charging system is widely used in stereo garages in the future. It is characterized in that the vehicle-mounted automatic socket 09 includes a charging socket shell 091, a conductive ring 912, a terminal 093, a terminal screw 914, a socket base 095, a socket cover 096, and a signal generator 097. The charging socket shell 091 is flat in shape, and the terminal 093 made into a flat strip shape at the front end is installed in a fan-shaped ray manner to connect the corresponding The conductive ring 912 has a terminal screw 914 installed at the tail to connect with the corresponding wires of the car. The flat socket base 095 is used to seal, insulate and waterproof each conductive connection. The socket cover 096 is made into a waterproof sealing cover in the form of an automatic sliding switch like a car sunroof and is installed on the car roof. If charging is needed when parking the car, the driver can open the socket cover 096 before the vehicle is parked. The signal generator 097 is installed in the center of the charging socket shell 091 to facilitate the accurate alignment and insertion of the conical charging plug 84 on the power supply device 80 on the top of the parking space in the three-dimensional parking garage.
