[0002] In modern urban life, with the increasing number of cars, the problem of parking difficulty has become increasingly prominent. In order to make full use of space, three-dimensional parking garages have emerged, which can accommodate more vehicles in a limited area, thereby greatly increasing the number of parking spaces. However, the existing three-dimensional parking garages still have some shortcomings in design, especially in the wheel limit structure.
[0003] The wheel limit structure of traditional three-dimensional parking garages is often designed to be relatively fixed and cannot adapt well to vehicles with different wheel sizes and different wheelbases. When a vehicle is parked in such a parking garage, the vehicle may be parked unsteadily or even damaged due to the inappropriate wheel limit structure. This not only brings inconvenience to the car owner, but also increases the maintenance cost of the parking garage management. In view of this, we propose a wheel limit structure for a three-dimensional parking garage. Utility Model Content

When two adjacent strip plates are connected, the second protrusions are located in the grooves.
[0010] As a preferred technical solution, two adjacent strip plates are hinged via a hinge shaft, and two ends of the hinge shaft are fixedly connected to two second protrusions respectively.
[0011] As a preferred technical solution, the hydraulic cylinder is perpendicular to the side plate, and when its piston rod is extended, the chain plate structure bends toward the middle plate side.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0024] The wheel limiting structure of the three-dimensional parking garage comprises a mounting frame 1 and a turntable 2 rotatably connected in the mounting frame 1, a middle plate 3 is fixedly connected in the middle of the top of the turntable 2, a chain plate structure 4 is hingedly installed at both ends of the middle plate 3, and the chain plate structure 4 comprises a plurality of mutually hinged strip plates 40, the inside of the turntable 2 is hollow and an opening for installing the middle plate 3 and the chain plate structure 4 is opened at the top, a base 5 is fixedly connected under the middle plate 3 inside the turntable 2, and a side plate 50 arranged obliquely is welded on both sides of the base 5, and two hydraulic cylinders 6 are symmetrically fixedly installed on each side plate 50, and the piston rods of the two hydraulic cylinders 6 located on the same side plate 50 are hinged to one end of the chain plate structure 4 away from the middle plate 3. The middle plate 3 is hinged with the chain plate structure 4, and the bending of the chain plate structure 4 can be controlled by the extension and contraction of the hydraulic cylinder 6 during use, thereby realizing the limiting of the wheel. This structure can flexibly cope with the use of vehicles with wheels of different sizes and different wheelbases, thereby improving the versatility and convenience of the parking garage.
[0025] As a preferred embodiment of the present invention, a driving motor for driving the turntable 2 to rotate is installed at the bottom of the mounting frame 1, and the top of the turntable 2 is flush with the top of the mounting frame 1. By installing the driving motor at the bottom of the mounting frame 1, the turntable 2 can be easily driven to rotate, thereby adjusting the parking direction of the wheel. The top of the turntable 2 is flush with the top of the mounting frame 1, ensuring that the wheel can smoothly drive in and out of the parking garage.
[0026] As a preferred embodiment of the present invention, the bottom of the strip plate 40 at one end of the chain plate structure 4 away from the middle plate 3 is symmetrically integrally formed with two first protrusions 41, a fixed shaft 42 is fixedly connected between the two first protrusions 41, and two movable blocks 43 are rotatably connected on the circumferential outer wall of the fixed shaft 42, and the two movable blocks 43 are respectively fixedly connected to the piston rods of the two hydraulic cylinders 6 on the same side plate 50. The end of the chain plate structure 4 away from the middle plate 3 is connected to the piston rod of the hydraulic cylinder 6 through the first protrusion 41, the fixed shaft 42 and the movable block 43. Such a design enables the hydraulic cylinder 6 to stably and effectively control the bending degree of the chain plate structure 4, thereby realizing the limiting of the wheel.
[0027] As a preferred embodiment of the present invention, two second protrusions 44 are symmetrically formed on the outer wall of one side of the strip plate 40, and two grooves 46 are symmetrically formed on the outer wall of the other side. When two adjacent strip plates 40 are connected, the second protrusions 44 are located in the grooves 46. The two adjacent strip plates 40 are hinged by a hinge shaft 45, and the two ends of the hinge shaft 45 are fixedly connected to the two second protrusions 44 respectively. The strip plates 40 are hinged to each other through the second protrusions 44, the grooves 46 and the hinge shaft 45. Such a design allows the chain plate structure 4 to be flexibly bent and stretched to adapt to wheels of different sizes and vehicles with different wheelbases. At the same time, the hinged connection method also ensures the stability and durability of the chain plate structure 4.
[0028] As a preferred embodiment of the present invention, the hydraulic cylinder 6 is perpendicular to the side plate 50, and when the piston rod thereof is extended, the chain plate structure 4 bends toward the middle plate 3. Two adjacent strip plates 40 are hinged by a hinge shaft 45, and both ends of the hinge shaft 45 are fixedly connected to two second protrusions 44, respectively.
[0029] As a preferred embodiment of the present invention, when the chain plate structure 4 is placed horizontally, its top is flush with the top of the middle plate 3, and the top of the middle plate 3 is flush with the top of the turntable 2. When the chain plate structure 4 is placed horizontally, its top is flush with the top of the middle plate 3. Such a design ensures that the wheels can smoothly drive in and out of the parking garage, avoiding bumps and damage caused by height differences. At the same time, the top of the middle plate 3 is flush with the top of the turntable 2, which further ensures the smooth driving in and out of the wheels.
[0030] As a preferred embodiment of the present invention, when the piston rod of the hydraulic cylinder 6 is retracted to the shortest position, the chain plate structure 4 is placed horizontally, and the end of the piston rod is located below the top opening of the turntable 2. When the piston rod of the hydraulic cylinder 6 is retracted to the shortest position, the chain plate structure 4 is placed horizontally. This design allows the chain plate structure 4 to remain horizontal when no vehicle is parked, without affecting the normal use of the parking garage. At the same time, the end of the piston rod is located below the top opening of the turntable 2, ensuring that the piston rod can extend from the opening to the outside of the turntable 2.
[0031] When the wheel limiting structure of the three-dimensional parking garage of the utility model is in use, when a vehicle needs to be parked in the three-dimensional parking garage, first, the vehicle will drive towards the turntable 2. At this time, the chain plate structure 4 is in a horizontal state and is flush with the top of the middle plate 3, ensuring that the vehicle can drive in smoothly.
[0032] Next, drive the vehicle onto the chain plate structure 4 and the middle plate 3, ensure that the wheel is located on the chain plate structure 4, and then control the piston rod of the hydraulic cylinder 6 to extend and retract. When the piston rod of the hydraulic cylinder 6 is extended, the chain plate structure 4 will begin to bend at the hinge of the middle plate 3 to form a certain arc. At this time, the strip plate 40 pressed by the wheel will not move, and only the strip plate 40 located on the outside of the wheel will flip with the extension of the piston rod of the hydraulic cylinder 6 until a strip plate 40 is tightly fitted with the outer wall of the wheel. Then the hydraulic cylinder 6 will stop working and maintain the current bending degree, thereby limiting the wheel. This limiting method can ensure that the wheel will not slide or move in the parking garage, improving the safety and stability of parking.
[0033] During the bending process of the chain plate structure 4 , since the strip plates 40 are hinged to each other via the hinge shafts 45 , the chain plate structure 4 can bend flexibly without being broken or damaged.
[0034] When the vehicle needs to drive out of the parking garage, the piston rod of the hydraulic cylinder 6 will shrink, so that the chain plate structure 4 gradually returns to a horizontal state. In this way, the wheels can smoothly drive out of the parking garage without any hindrance.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
