At present, in commercial streets, subway entrances, residential areas and other places with concentrated populations, the problem caused by the large-scale parking of two-wheeled vehicles is serious, which seriously affects the normal life and traffic environment. Therefore, three-dimensional parking racks have gradually appeared.

[0064] The positioning housing 611 is fixed at each parking position of the corresponding layer of the vehicle frame. Vertical openings are symmetrically arranged at the lower ends of the positioning housing 611. The vertical openings are used for the lifting and positioning channels of the lower coupler 443. The central pin shaft 615 in the center of the positioning housing 611 is rotatably connected to a transition gear 614, and a horizontal upper rack 612 and a lower rack 613 are arranged in the upper and lower guide cavities thereof. The upper and lower ends of the transition gear 614 respectively mesh with the inner ends of the upper rack 612 and the lower rack 613. The upper rack 612 and the lower rack 613 move laterally, fit together and gradually support the lower coupler 443 that is lifted up and enters the vertical opening, so that the movable guide wheel 442 is upwardly separated from the support of the flexible rope 42; or gradually separates from and releases the lower coupler 443, so that the movable guide wheel 442 is downwardly fitted with the support of the flexible rope 42.

[0067] Furthermore, an upper positioner 61 is installed on each of the several parking positions of the front and rear cross beams 13 of the parking frame.

There is a longitudinal hole in the center of the U-shaped tube, and there are vertical openings with a bottom plate passing through on both sides, and there are oblique guide edges at the entrance, and the center pin 615 is inserted into the horizontal through hole.

[0068] Further, the center pin 615 is an active component, and the positioning power 62 is a rotational power that drives the center pin 615 to rotate.

The extended end of a driving motor is connected to a horizontally placed transmission shaft, and a plurality of active bevel gears are installed on the transmission shaft, and each active bevel gear is meshed with an outer bevel gear of the electromagnetic clutch; the working principle of the rotational positioning power: when a certain electromagnetic clutch is energized and engaged, after the driving motor is started, through the transmission shaft, the active bevel gear, the electromagnetic clutch and the center pin transmission, the transition gears on both sides can be synchronously driven to rotate. Here, the center pin 615 and the transition gear 614 can be connected by a key to drive the upper rack and the lower rack to move laterally, thereby realizing the operation of the upper positioner 61.

[0069] Either the upper rack 612 or the lower rack 613 is an active component, and the positioning power 62 is a linear power output part that drives the upper rack 612 or the lower rack 613 to move horizontally.

[0070] Furthermore, the positioning power 62 is a driving device power shared by all the positioners 61, and can drive one group of positioners 61 separately; usually, it is preferred to set two front and rear positioners 61 in each group, and a lifting frame 44 is placed under a group of positioners 61;

[0071] The positioning power 62 adopts a linear power output part, including: an electric push rod 621, a positioning push rod 622, a positioning push block 623, a push rod support wheel 624, a push rod pressure wheel 625, a first electromagnetic lock 626, and a traction support 627; a plurality of horizontal holes are drilled on one side of the positioning push rod 622; a rectangular opening is opened on the inner side plate of the positioning housing 611 and the inner side plate of the top crossbeam 13, and the length of the opening is greater than the horizontal stroke of the upper rack 612; a traction support 627 is horizontally installed on the tooth surface end of each upper rack 612, and a first electromagnetic lock 626 is installed on the traction support 627, and the lock tongue can extend out of the rectangular opening of the side plate of the positioning housing 611 and the upper rack 612 after power is turned on, and can be inserted into the horizontal hole at the corresponding position of the side of the positioning push rod 622 installed horizontally on the side;

[0072] Each electric push rod 621 is placed horizontally, with one end installed on the end beam 12 at one end of the parking frame, and the other end connected to the positioning push block 623 fixed at the end of the positioning push rod 622, so that the electric push rod 621 can synchronously push the two positioning push rods 622 to move linearly horizontally through the positioning push block 623; the push rod supporting wheel 624 and the push rod pressure wheel 625 are respectively located below and above the positioning push rod 622, with a certain distance from each other, and are horizontally installed on the side plate of the top beam 13 through a pin shaft, constraining the positioning push rod 622 to move longitudinally and linearly between the two.

[0073] Furthermore, the lifting frame 44 is a lifting device, including: a lifting frame 441, a movable guide wheel 442, and a lower connector 443. The lifting frame 441 is a horizontal rectangular frame, and four movable guide wheels 442 are installed at both ends of the two end beams through horizontal pins; and the lower connector 443 is installed in the middle section of each end beam. The lifting frame 441 is vertically connected to the parking device 3 below to form a three-dimensional frame for storing two-wheeled vehicles that can be lifted up and down.

[0074] Working principle of positioning device 6: When a high-rise parking device 3 needs to store or retrieve a vehicle, firstly, the first electromagnetic lock 26 on each transverse shift frame below the parking device 3 in each transverse shifter 2 below the layer is energized and each lock tongue is extended and inserted into the corresponding horizontal hole on each transverse shift push rod 20, and then each transverse shift force 21 is started to push the multiple transverse shift frames below to shift horizontally, so that the space below the parking device 3 on each layer below becomes empty;

[0075] Secondly, the first electromagnetic lock 626 at the parking device 3 is energized, and the lock tongue is extended and inserted into the corresponding horizontal hole on the positioning push rod 622. Then the electric push rod 621 is started, and the push rod is extended, driving the upper and lower inclined racks in the upper positioner 61 to retract, thereby releasing the lower connector 443 and allowing the lifting frame 44 to reach the support of the wire rope 42. Finally, the lifting power 41 is started, and the lifting frame 44 is driven by the lifting part 4 to move downward until the parking device 3 reaches the ground, and the vehicle is stored or taken out;

[0076] Then, the lifting power 41 starts in reverse, and the lifting frame 44 is driven by the lifting part 4 to make an upward movement before approaching the highest point. When the lower coupler 443 installed on the lifting frame 44 is respectively higher than the lowest point of the upper and lower inclined racks of the locator 61, a group of first electromagnetic locks 626 there are energized, and the lock tongue is extended and inserted into the horizontal hole at the corresponding position on the side positioning push rod 622, the electric push rod 621 is started and the push rod retracts, pushing the lower coupler 443 to the highest point, and the fixed pulley 442 on the lifting frame 44 is separated from the wire rope, so that the upper locator 61 is supported and positioned at this layer, the first electromagnetic lock 626 is powered off and the lock tongue is retracted; the entire access operation is completed.

[0077] The function of the positioning device 6 is to slightly lift the lifting basket to the highest point and position it so that the height of the lower bottom groove of the movable guide wheel 443 thereon exceeds the height of the upper bottom groove of the fixed guide wheel 43 of the lifting parts 4 on both sides, that is, all lifting frames 44 are at the highest and positioned in the parking space, and the flexible rope 42 steel wire rope is in a horizontal straight line state. The beneficial effect is that only one set of fixed and movable pulleys are subjected to force each time the operation is performed, and at the same time, the lifting resistance and the wear of the steel wire rope are reduced. Normally, the lifting frame, the parking device 3 and the vehicle are not carried on the flexible rope 42, and the lifting frame, the parking device 3 and the vehicle will not fall due to the breakage of the flexible rope 42. Similarly, as above, once a certain upper positioner 61 fails, the equipment it carries will only fall on the steel wire rope, and the two play a double protective role with each other.

[0078] The beneficial effect of installing the positioning part 6 in the lifting part 4 is that only one set of power and transmission device is used for the lifting movement and positioning support action of multiple lifting frames on each high level, so that the entire level can independently drive the lifting movement and support positioning of a certain parking storage device 3.

[0079] Further, the parking device 3 includes: a chassis 31, a clamp 32, a sliding track 33 and a front wheel suspension 36;

[0080] The chassis 31 includes a horizontally arranged pallet 311, and the pallet 311 is connected to the lifting frame on both sides longitudinally through side frames. The space defined by the pallet 311, the two side frames and the lifting frame is a parking cavity. Preferably, the chassis 31 also includes two side guide plates 312 for guiding the tire's in and out movement direction, and the two side guide plates 312 are symmetrically connected on both sides of the center line of the pallet 311.

[0081] Two sliding rails 33 are respectively arranged on the inner sides of the two side frames;

[0082] The clamping frame 321 of the clamp 32 is fixed to the front side of the bracket 311, and two clamping plates 323 for clamping the front wheel are symmetrically installed on the rear end of the clamping frame 321. The two clamping plates 323 can move towards each other to clamp and fix the front wheel tire or move away from each other to open and release the tire.

[0083] The front wheel suspension 36 includes two sliding frames 361 and a plurality of sliding wheels 362. The two sliding frames 361 are respectively fixed on the two longitudinal upper ends of the clamping frame 321, so that the sliding frame 361 and the clamp 321 become a rigid whole. A sliding wheel 362 is respectively installed at the front and rear ends of the sliding frame 361, and the sliding wheel 362 slides in the sliding track 33. When parking the car, the clamp 32 and the front wheel suspension 36 slide to the front end of the storage cavity as the two-wheeled vehicle is pushed. When taking the car out, the clamp 32 and the front wheel suspension 36 slide to the rear end of the storage cavity, that is, the entrance of the storage cavity, as the two-wheeled vehicle is pulled out. The beneficial effects are as follows: first, semi-automatic storage is realized. When the vehicle enters the parking device 3, the front wheel enters the clamp 32, and the clamp 32 is manually operated to clamp the front and lower circumference of the front wheel of the vehicle, ensuring that the vehicle will not tip over under the premise that the human hand is off the handlebars and the rear is supported. Then the vehicle is pushed forward in a straight line until the rear wheel of the vehicle is pushed onto the chassis 31 and all enters the parking device 3. People do not need to enter the parking frame 3, which not only ensures the safety of users, but also reduces the area of ​​the parking frame 3 or eliminates the pedestrian space on one side, so that more vehicles can be stored in the same area; second, the clamp 32 can ensure that the vehicle is flexibly and lightly pushed into the parking device 3 in a straight line, and can also prevent the vehicle from tipping over and falling sideways; third, the two sliding rails 33 and the two side guide plates 312 below will serve as support members to resist the tipping of the vehicle, preventing the vehicle from tipping over during the process of pushing the vehicle in.

[0084] Preferably, the sliding frame 361 is an inverted U-shaped structure, and a group of sliding wheels 362 are installed on both sides of the two ends of the horizontal beam on the sliding frame 362. The sliding wheels 362 are symmetrically embedded in two sliding rails 33 horizontally installed on the inner side of the front suspension rod 34 and the rear suspension rod 35, so that the clamp 32 can slide horizontally under the two sliding rails 33, and the lower end of the clamp 32 is embedded in the middle of the two side guide plates 312 on the chassis 31.

[0085] Furthermore, the side frame includes two front suspension rods 34 and two rear suspension rods 35. The lower ends of the two front suspension rods 34 are symmetrically fixed to the front end of the support plate 311 and the upper ends are fixed to the corresponding hanging frames. The lower ends of the two rear suspension rods 35 are symmetrically or longitudinally staggered to the rear end of the support plate 311 and the upper ends are fixed to the hanging frames. The beneficial effect is that the longitudinal staggered setting can further save space.

[0086] Preferably, the two front suspension rods 34 are located in front of the handlebars, and the lateral spacing may be smaller than the width of the handlebars; the two rear suspension rods 35 are basically located at the vertical center of the rear wheel of the vehicle, and there are outward bending sections on both sides in the middle section at the height of the handlebars. The horizontal width of the space in the two bending sections is greater than the width of the handlebars, and the handlebars can pass through longitudinally, and the two rear suspension rods 35 are installed with a longitudinal gap of one suspension rod height. The beneficial effect is: the center distance between two adjacent parking devices 3 is minimized, and the rear suspension rods 35 do not collide due to protruding outward.

[0087] Furthermore, in order to ensure that the vehicle cannot fall from the parking device 3 , a fall prevention device 37 is installed at the rear end of the support plate 311 of the chassis 31 .

[0088] Preferably, the anti-fall device 37 includes: a support bracket 371, a speaker chute 372, and a fixed support 373. The support bracket 371 is a foot-operated, spring-locked double-bracket accessory for electric vehicles. The two fixed supports 373 are symmetrically installed on the rear end edge of the support plate 311. The support bracket 371 is horizontally installed on the two fixed supports 373 by bolts, and the speaker chute 373 is fixed to the cross-link under the support leg of the support bracket 371, so that when the speaker chute 372 is in the lowest basic horizontal state, the small mouth of the speaker is inserted into the inner side of the side guide plate 312, becoming an inclined springboard for entering and exiting the support plate entrance and exit. By stepping on the lever on the support bracket 371, the support bracket 371 is in the highest upward tilted state, so that the speaker chute 372 serves as a barrier to the rear wheel of the vehicle, and the springs on the support bracket 371 are locked at both positions; the beneficial effect is: it is convenient for two-wheeled vehicles to be pushed in and out of the parking device 3, and prevents the two-wheeled vehicle from falling after entering the parking device 3.

[0089] Furthermore, the clamp 32 further includes an arc plate 322, a return spring 324, a wedge block 325, and an operating pressure rod 326. The clamp frame 321 is a three-dimensional bilaterally symmetrical rod frame. Clamping plates 323 are installed on both sides of the arc plate 322. The upper end of the arc plate 322 is vertically connected to the center of the upper end horizontal plate of the clamp frame 321, and the lower end is embedded in the middle of the two side guide plates 312.

[0090] Clamping plates 323 are installed on both sides of the arc plate 322.

[0091] The outer back side of the clamping plate 323 has a vertical inclined surface and several horizontal supporting sliding shafts, and the horizontal sliding shaft is inserted into the corresponding sliding sleeve on the clamping frame 321. A return spring 324 is installed at the end of each extended horizontal sliding shaft to maintain the two clamping plates 323 in an initial open state; the swing fulcrum of the operating pressure rod 326 is set at the front lower end of the clamping frame 321, and a sliding wedge block 325 is placed on each inclined surface on the back side of the clamping plate 323. The wedge block 325 is connected to the front end hole on the operating pressure rod 326 through a connecting rod. Manually swinging the operating pressure rod 326 up and down can drive the two wedge blocks 325 to move up and down synchronously on the inclined surface on the back side of the clamping plate 323, so that the wedge block 323 generates a pair of horizontal squeezing forces on the inclined surface, so that the two clamping plates 323 can realize the opening or clamping action. The beneficial effect is that the clamping opening of the clamp is automatically and steplessly adjusted according to the width of the clamped front wheel, and can adapt to the width of the front tires of vehicles with different specifications.

[0092] Preferably, the clamping force on both sides of the front wheel can be adjusted by increasing or decreasing the weight at the tail end of the long rod section of the operating pressure rod 326 .

[0093] Preferably, the inner side of the clamping plate 323 is a plane, and a soft rubber plate is attached to the inner side of the plane to protect the vehicle tire.

[0094] The operation procedure for storing electric vehicles on the first floor is as follows: operate the anti-fall device 37 by foot, align the electric vehicle with the empty parking device 3 in a straight line, manually lift the operating pressure rod 326 of the clamp 32, and the two clamping plates 323 expand under the action of the return spring 324, push the vehicle into the clamping frame 321 until the arc plate 322 manually presses down the operating pressure rod 326, and the wedge blocks 325 on both sides descend, and the two clamping plates 323 clamp the front wheels of the vehicle, and continue to push the vehicle in. The front wheels of the vehicle are clamped by the clamp 32, and the rear wheels roll on the ground and enter in a straight line along the sliding track 33. The rear wheels roll on the ground until the rear wheels enter the parking device 3, and then the anti-fall device 37 is closed by foot.

[0095] Furthermore, the sliding rail 33 and the side guide plate 312 are structures that turn horizontally to the left at the front end, that is, the clamp 32 can be deflected at an angle when it reaches the front end. The parking garage is designed so that the number of parking spaces on each floor can allow one more vehicle to be inserted into the floor. According to the specifications of two-wheeled vehicles, the single parking rack of this method is designed to park approximately the number of vehicles on the top floor after the same number of vehicles on the bottom floor is parked in a turning manner, and the number of vehicles parked on the bottom floor does not need to be less than the number of vehicles parked on the top floor. When the vehicle is not stored or taken out, the lateral distance between two adjacent vehicles parked in this way can be smaller; the beneficial effect is: without reducing the number of vehicles parked on the original floor, more parked vehicles are added in the vertical space above;

[0096] Furthermore, explosion-proof panels are used on the top and bottom, left and right, front and back of the parking device 3 to form a fully sealed parking box structure, thus forming an explosion-proof and fire-proof three-dimensional parking garage system for two-wheeled vehicles.

[0097] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
