[0048] It should be noted that the first standby component 8 and the first parking component 4, the first parking component 4 and the second parking component 5, and the second parking component 5 and the second standby component 9 can be connected side by side through the connecting rod 13. The connecting rod 13 includes a support column 54 and sliding pins 55 provided on both sides of the support column 54, and the sliding pins 55 are used to connect adjacent components.

[0050] When the foldable variable volume garage device provided by the present invention is used, the upper frame 1 and the lower frame 2 are in an overlapping state in the initial state, and the first spare assembly 8 and the second spare assembly 9 are vertically arranged on the left and right sides of the upper frame 1. If the flow of people is small and the demand for parking spaces is small, the vehicle can be parked on the first parking assembly 4 and the second parking assembly 5 to realize the parking operation of two vehicles.

[0051] However, when the flow of people is large and the demand for parking spaces is large, the vehicle can be parked on the first parking assembly 4 and the second parking assembly 5 first, and the locking device 53 can be used to lock the vehicle. Then, the driving device 10 can be controlled to drive the first parking assembly 4 and the second parking assembly 5 to fold into an inverted V shape, thereby leaving space for laying the first spare assembly 8 and the second spare assembly 9 flat, and then other vehicles can be parked on the locking devices 53 of the first spare assembly 8 and the second spare assembly 9, thereby realizing the parking operation of four vehicles and doubling the parking space volume ratio.

[0052] In addition, if the demand for parking spaces cannot be met, the lifting device 3 can be controlled to operate so that the upper rack 1 with four vehicles is lifted relative to the lower rack 2, so that the lower rack 2 can park the vehicles, and then the other two vehicles are parked on the locking devices 53 of the third parking assembly 6 and the fourth parking assembly 7, and finally six vehicles can be parked, so that the volume ratio of the parking space is increased by three times. When it is necessary to unload the vehicles on the upper rack 1, the conveying device 11 can be used to connect the raised upper rack 1 to the ground, so that the vehicles can leave the parking space.

[0053] Since the first parking assembly 4, the second parking assembly 5, the third parking assembly 6, the fourth parking assembly 7, the first spare assembly 8 and the second spare assembly 9 are all provided with a locking device 53, safety hazards such as tipping over and rolling of the vehicle during folding or lifting can be avoided.

[0054] In summary, the foldable variable-volume garage device provided by the present invention can enable the parking device to expand the parking space capacity according to actual needs.

[0055] On the basis of the above embodiments, preferably, the first parking component 4 and the second parking component 5 have the same structure, and the first parking component 4 includes a parking frame 14, two wheel grooves 15 arranged along the length direction of the parking frame 14, a locking device 53 that can slide relative to the wheel groove 15, a slide rail 16 that can move along the track groove 12, a fixed rod 17 arranged parallel to the width direction of the parking frame 14, and a first hydraulic cylinder 18 for pushing the parking frame 14 to overturn, the slide rail 16 is arranged on the fixed rod 17, one end of the first hydraulic cylinder 18 is hinged to the end of the parking frame 14, and the other end is hinged to the fixed rod 17.

[0056] When the driving device 10 drives the first parking component 4 and the second parking component 5 to perform a folding operation, the slide rails 16 of the first parking component 4 and the second parking component 5 can move along the track groove 12 to drive the fixing rod 17 to move along the track groove 12. When the fixing rod 17 moves, it will drive one end of the first hydraulic cylinder 18 to move synchronously. At this time, the first hydraulic cylinder 18 can be controlled to operate, and the two ends of the first hydraulic cylinder 18 are extended to pull the parking frames 14 of the first parking component 4 and the second parking component 5 to flip sideways through the first hydraulic cylinder 18, and finally the first parking component 4 and the second parking component 5 can form an inverted V shape. After the first parking component 4 and the second parking component 5 are folded, a parking space can be vacated to facilitate the flat placement of the first spare component 8 and the second spare component 9.

[0057] It should also be noted that the parking frame 14 and the fixed rod 17 here are both hinged to the first hydraulic cylinder 18, which may mean that two first hydraulic cylinders 18 are arranged on the front and rear sides of the parking frame 14, and the first hydraulic cylinders 18 on the same side are connected to the parking frame 14 and the fixed rod 17 through hinges 19, and the hinged position of the two first hydraulic cylinders 18 and the fixed rod 17 is in the middle of the parking frame 14, so that the first hydraulic cylinder 18 can drive the parking frame 14 to flip and fold.

The arm 25 and the second arm 29 are both perpendicular to the screw 20, the arm seat 30 is provided with a threaded hole 31 which can be sleeved on the outer periphery of the screw 20, the first driven gear 24 and the second driven gear 28 are both meshed with the driving gear 26, and the rotation directions are opposite; the locking device 23 includes a lock seat 32, a retractable lock pin cylinder 33 and a mounting seat 34 for mounting the lock pin cylinder 33, the lock seat 32 is provided with a threaded hole 31 which can be sleeved on the outer periphery of the screw 20, the mounting seat 34 is arranged on the lock seat 32, and the telescopic ends of the lock pin cylinder 33 are respectively locked with the lock holes of the first arm 25 and the second arm 29.

[0059] It should be noted that when the vehicle enters the wheel groove 15 of the parking rack 14, the screw motor 21 can be controlled to operate to drive the locking device 22 and the locking device 23 on the screw 20 to move along the direction of the vehicle groove to ensure that the locking device 22 and the locking device 23 move to the wheel position of the vehicle and cooperate to lock the wheel to avoid the vehicle falling during the subsequent folding process.

[0060] In addition, it should be noted that when the driving gear 26 rotates, the first driven gear 24 and the second driven gear 28 can be driven to rotate in the opposite direction. When the first driven gear 24 and the second driven gear 28 rotate, the first arm 25 and the second arm 29 can be driven to move closer to or farther from each other, so as to facilitate the clamping and fixing of the wheel. At the same time, the locking pin cylinder 33 can operate synchronously to ensure that the telescopic end of the locking pin cylinder 33 is respectively locked with the locking holes of the first arm 25 and the second arm 29, thereby locking the wheel and ensuring that the vehicle is fixed. The coordinated arrangement of the locking device 22 and the locking device 23 can avoid the safety hazard of the vehicle tipping over when the parking rack 14 is in the folded state. Moreover, the different rotation directions of the driving gear 26 and the driven gear are used to realize the closing and opening control of the arm, which has higher reliability and longer service life than the electronic drive closing system.

[0061] Preferably, the driving device 10 includes a first support rod 35, a second support rod 36 and a second hydraulic cylinder 37, the first support rod 35 is vertically connected to the two fixed rods 17 of the first parking component 4, the second support rod 36 is vertically connected to the two fixed rods 17 of the second parking component 5, and the telescopic ends of the second hydraulic cylinder 37 are vertically connected to the first support rod 35 and the second support rod 36 respectively.

[0062] It should be noted that when the first parking assembly 4 and the second parking assembly 5 need to be folded, the second hydraulic cylinder 37 can be controlled to operate, and the second hydraulic cylinder 37 can drive the first support rod 35 and the second support rod 36 to approach each other. When the first support rod 35 and the second support rod 36 approach each other, they can drive the fixing rod 17 of the first parking assembly 4 and the second parking assembly 5 to approach each other, and the movement of the fixing rod 17 will cause the parking rack 14 of the first parking assembly 4 and the second parking assembly 5 to flip and fold sideways, and finally form an inverted V-shaped structure. The driving schematic diagram of the driving device 10 is shown in FIG. Figure 6 As shown, the arrows in the figure indicate the running directions of the corresponding components.

[0063] In actual use, the shape, structure, size, position, etc. of the first support rod 35, the second support rod 36 and the second hydraulic cylinder 37 can be determined according to actual conditions and actual needs.

[0065] It should be noted that when the first parking assembly 4 and the second parking assembly 5 form an inverted V shape, the parking spaces originally occupied by the first parking assembly 4 and the second parking assembly 5 will be vacated, so that the first spare assembly 8 and the second spare assembly 9 can be placed flat. The locking device 22 and the locking device 23 of the first spare assembly 8 and the second spare assembly 9 can effectively lock the vehicle to ensure the fixed parking effect of the vehicle. In addition, the different rotation directions of the driving gear 26 and the driven gear are used to realize the closing and opening control of the arm, which has higher reliability and longer service life than the electronic drive closing system.

At this time, the three groups of unloading motors 42 of the unloading drive 39 can be controlled to operate to drive the three groups of unloading gears 43 to rotate, thereby driving the rack 45 on the unloading folding plate 38 to slide along the conveying rail 41 to the outside of the first parking assembly 4 and the second parking assembly 5, and the third hydraulic cylinder 40 lifts the conveying rail 41 to form an angle with the fixed plate 44, so that the unloading folding plate 38 contacts the ground of the lower frame 2, and then unfolds the three folding plates 56, so that the vehicle can be parked and locked on the first parking assembly 4 and the second parking assembly 5 of the upper frame 1 through the folding plates 56.

In addition, after the vehicle is parked, the unloading driving member 39 and the unloading folding plate 38 can be reset by the reverse movement of the above movement, thereby saving space.

[0078] Therefore, the device can realize the parking of two vehicles when it is idle and the parking of six vehicles when it is busy, so that the volume ratio of the parking space is increased by 3 times. Moreover, the lifting and folding design concept is adopted to realize the folding and expansion of the parking spaces of the upper frame 1 and the lower frame 2, and the parking space of the upper frame 1 can also realize the rapid parking operation of the car through the unloading drive member 39 and the unloading folding plate 38, which improves the parking efficiency of the car and solves the problem that the upper parking space cannot be docked and unloaded.
