Description

Technical Field

[0001] This utility model relates to the field of car parking rack technology, specifically to a three-dimensional car parking rack that facilitates positioning. Background Technology

[0002] With the increase in car usage, underground parking lots and other areas have limited horizontal parking space, making it difficult to meet the large parking demand. Therefore, multi-level parking racks are installed. By raising cars and placing them in the racks, the parking area is increased by utilizing vertical space, which can effectively solve the problem of insufficient parking spaces.

[0003] Chinese utility model patent CN219910220U discloses a three-dimensional parking device, which includes "a three-dimensional parking frame and several parking plates set inside the three-dimensional parking frame. The top of the parking plate has two through slots that symmetrically penetrate the parking plate. The bottom of the parking plate is provided with a limiting component. Each through slot is provided with a limiting block. The bottom of the limiting block is connected to the limiting component." By setting through slots and limiting blocks in fixed positions, the tires of cars parked on the parking plate are restricted. However, since different types of vehicles have different lengths and wheelbases, it is not convenient to adapt to the use of different vehicles. Utility Model Content

[0004] The purpose of this utility model is to provide a three-dimensional car parking rack that is easy to limit, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a three-dimensional car parking rack that facilitates positioning, comprising a three-dimensional parking rack body, a parking plate for placing a vehicle fixedly connected to the top of the three-dimensional parking rack body, two through grooves for blocking the rear wheels opened on the outer wall of the parking plate, a drive motor fixedly connected to the inner wall of the parking plate, and a transmission screw fixedly connected to the main shaft end of the drive motor.

[0006] The transmission lead screw is equipped with a limiting mechanism for restricting vehicle movement.

[0007] Preferably, the limiting mechanism includes a drive plate threadedly connected to the outer wall of the transmission screw, the drive plate being used to push the limiting block and the wheel to contact and limit the movement of the vehicle;

[0008] The front end of the drive plate is horizontally provided with a support chassis, which is used to support the limiting block. Both ends of the support chassis are fixedly connected with support plates, and guide rods for stabilizing and guiding the movement of the support plates are inserted into both support plates. Both ends of the two guide rods are fixedly connected to the inner wall of the parking plate.

[0009] Both support plates are provided with locking elements for locking the support plates.

[0010] Preferably, the limiting mechanism further includes a limiting block inserted into the supporting chassis, the limiting block being used to block and restrict the movement of the vehicle in front of the rear wheels;

[0011] A protrusion is fixedly connected to the side wall of the limiting block. One end of the protrusion is slidably connected to a guide groove opened on the inner wall of the parking plate. The guide groove is set in a U-shape. The limiting block slides in the guide groove through the protrusion to control its own height.

[0012] Two symmetrically arranged inflation chambers are provided on the outer wall of the support plate. A release port is provided on the side wall of the inflation chamber. A buffer rod is slidably connected in the inner wall of the inflation chamber. The end of the buffer rod away from the inflation chamber is fixedly connected to the drive plate.

[0013] To avoid or reduce damage to the device:

[0014] The buffer rod and the inner wall of the inflation chamber are connected by a compression spring, and a trigger sensor is horizontally arranged at the front end of the buffer rod. The trigger sensor is fixed in the inner wall of the inflation chamber and is electrically connected to the drive motor.

[0015] By adopting the above technical solution, when the drive plate pushes the support chassis through the buffer rod, it can be pushed to move by the compression spring. When the limit block on the support chassis contacts the wheel, the buffer rod can first squeeze the compression spring, trigger the locking component to lock, and at the same time, the drive motor stops working by triggering the sensor, thus avoiding wear of the equipment caused by the rigid connection between the buffer rod and the support chassis.

[0016] Preferably, the locking component includes a limiting post fixed inside the support plate, a control disk rotatably connected to the front end of the limiting post, and a limiting plate for locking the guide rod rotatably connected to the outer wall of the control disk;

[0017] The shaft ends of the limiting plate and the control disk are eccentrically arranged. A sliding rod is fixedly connected to the front end of the top of the control disk. Several limiting plates are arranged in a ring array about the axis of the support plate.

[0018] To achieve stable clamping of the guide rod by several limiting plates:

[0019] Further configuration: one end of the limiting plate is a semi-circular arc structure, and the semi-circular arc end is made of rubber material.

[0020] By adopting the above technical solution, several limiting plates are eccentrically rotated, and the semi-circular arc structure at the bottom of the limiting plate can be tightly pressed against the guide rod, limiting radial movement and achieving a locking effect.

[0021] Preferably, the outer wall of the limiting post is provided with a plurality of sliding grooves arranged in a circular array, and the plurality of sliding grooves are slidably engaged with the sliding rods on the limiting plate to stably drive the limiting plate to move eccentrically.

[0022] Preferably, the locking component further includes a cover plate fixed to the front end of the control panel, and there is an installation gap between the cover plate and the control panel for installing a limiting plate, and the inner sidewalls of the limiting plate and the cover plate rotate eccentrically.

[0023] A connecting rod is fixedly connected to the front end of the shielding plate. The connecting rod is offset from the limiting plate. The connecting rod is a telescopic rod structure. A telescopic air rod is hinged to the front end of the connecting rod. One end of the telescopic air rod is fixed inside the support plate. One end of the telescopic air rod is connected to the inflation chamber through an air supply pipe.

[0024] The beneficial effects of this utility model are as follows:

[0025] In this utility model, by setting up a supporting chassis and a supporting plate, the limiting block can be driven to extend and move to abut against the front end of the rear wheel of the car after the vehicle passes, thereby limiting the car and adapting to different vehicles.

[0026] In this invention, by setting a locking component, the horizontal forward and backward movement of the limiting block is locked while the limiting block restricts the wheel, thereby reducing the pressure of the lead screw self-locking, avoiding damage to the transmission structure, and improving the limiting effect.

[0027] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0051] The computer software involved in the hardware carriers such as the three-dimensional parking frame body, trigger sensors, and drive motors in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned hardware carriers, nor is it a key technical point of the invention.

[0052] Therefore, the "three-dimensional parking rack body", "trigger sensor", "drive motor" and other components involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, in order to solve the corresponding technical problems to be solved by this application.

[0053] The working process of this convenient three-dimensional car parking rack is as follows:

[0054] First, the car is backed onto the parking platform 2. Then, the two drive motors 4 in the parking platform 2 drive the two transmission screws 5. The transmission screws 5 push the compression spring through the buffer rod 610 on the drive plate 61. The compression spring pushes the support chassis 62 to slide on the bottom wall of the parking platform 2. Since the inflation chamber 69 has a release port, the displacement generated by the initial push is sufficient to exceed the release port. At this time, the inflation chamber 69 cannot trigger the locking member 65.

[0055] Then, as the supporting chassis 62 moves, the supporting chassis 62 slides stably on the two guide rods 64 through the two support plates 63. At the same time, the limiting block 66 on the supporting chassis 62 slides in the guide groove 68 through the protrusion 67 and gradually moves out of the through groove 3 and moves to the front of the rear wheel of the car. The limiting block 66 abuts against the rear wheel of the car, restricting the rotation of the rear wheel.

[0056] When the limiting block 66 contacts and abuts against the rear wheel of the car, the supporting chassis 62 can no longer move. At this time, the buffer rod 610 continues to compress the spring until the buffer rod 610 passes the release port. At this time, the release port is blocked. The continuous displacement of the buffer rod 610 can squeeze the gas in the inflation chamber 69 into the telescopic air rod 658 through the air supply pipe, so that the telescopic air rod 658 pushes the connecting rod 657 forward. Since the connecting rod 657 is a telescopic structure, the telescopic air rod 658 can push the control disk 652 to rotate. The control disk 652 rotates clockwise. Since the limiting plate 653 and the control disk 652 rotate eccentrically, the semi-circular arc surfaces at the bottom of several limiting plates 653 are pressed against the outer wall of the guide rod 64. At the same time, the top of the limiting plate 653 slides in the sliding groove 655 through the sliding rod 654 to ensure the stable movement of the limiting plate 653. At this time, several limiting plates 653 lock the guide rod 64, which can withstand the sudden loosening of the vehicle and the squeezing force of the wheel, increasing the safe use of the equipment.

[0057] At the same time, the buffer rod 610 will come into contact with the trigger sensor 7, and the trigger sensor 7 will generate an electrical signal to control the drive motor 4 to stop, thereby completing the limit process;

[0058] When contact is required, simply drive the transmission screw 5 in the opposite direction via the drive motor 4. The transmission screw 5 drives the drive plate 61 to reset, thereby extracting the gas from the telescopic air rod 658, causing the limiting plate 653 to reset and releasing the locking effect. At this time, the support chassis 62 can be reset via the drive plate 61 to release the restriction.
