Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, and more specifically, to a safety vehicle blocking device for automated parking systems. Background Technology

[0002] As a crucial facility for solving parking difficulties in modern cities, the safety and reliability of multi-level parking garages are of paramount importance. Among these, vehicle-stopping and anti-fall devices are a key component, used to prevent vehicles from accidentally moving or falling during parking, ensuring the safety of vehicles and people.

[0003] For example, document CN221400028U discloses a horizontal vehicle-stopping and anti-fall device for a three-dimensional parking garage. To prevent the top block from obstructing the wheels when a vehicle drives onto the platform, the top block is placed on both sides of the vehicle. After the vehicle is parked on the platform, an external control unit controls an electric push rod to move the top block outward until it moves to a position that matches the distance between the top block and the vehicle's tires. Then, a hydraulic rod is controlled to pull inward, which drives the electric push rod and the top block to move synchronously through a protrusion, so that the anti-slip pad on the top block fits against the outer wall of the vehicle's tires, thereby stopping the vehicle. The operation steps are relatively cumbersome and inefficient. Utility Model Content

[0004] This utility model provides a safety vehicle blocking device for a three-dimensional parking garage, which solves the technical problems of existing vehicle blocking devices having cumbersome operation steps and low efficiency.

[0005] To achieve the above objectives, this utility model proposes a three-dimensional parking garage safety vehicle blocking device, including a vehicle carrier plate. A wheel limiting block is fixedly connected to the inner wall of the vehicle carrier plate. A drive assembly and a connecting plate are installed inside the vehicle carrier plate. The drive assembly is used to drive the connecting plate to move and to adjust the distance between the connecting plate and the wheel limiting block. A rotating shaft is rotatably connected to both ends of the connecting plate. A connecting arm is fixedly connected to one end of each rotating shaft, and a limiting sleeve is fixedly connected to the other end of each rotating shaft. A torsion spring is sleeved on the outer circumference of each rotating shaft. A blocking mechanism is fixedly connected to the top of the connecting arm. A storage groove is opened at the bottom of the inner wall of the vehicle carrier plate, and the blocking mechanism is located in the storage groove. One end of the torsion spring is fixedly connected to the limiting sleeve, and the other end of the torsion spring is fixedly connected to the connecting plate. A stop block is fixedly connected to both ends of the connecting plate.

[0006] The above technical solution uses a drive component to move the connecting plate, adjusts the distance between the connecting plate and the wheel limit block, and uses the connecting arm and blocking mechanism to effectively block and position the vehicle, thus achieving automatic and effective blocking of the rear wheels of the vehicle and simplifying the parking blocking process.

[0007] Preferably, a groove is formed at the bottom of the inner wall of the vehicle carrier plate, and sliding grooves are formed on both sides of the inner wall of the groove. An extension groove is formed at the top of the inner wall of the sliding groove, and the extension groove extends to the bottom of the inner wall of the vehicle carrier plate. The width of the extension groove is greater than the width of the connecting arm and can accommodate the connecting arm to move along the length direction of the vehicle carrier plate.

[0008] Through the above technical solution, the groove provides installation space for the drive component and some connecting parts, the slide provides installation space for the slide rod, and the extension groove provides space for the movement of the connecting arm.

[0009] Preferably, the drive assembly includes two slide rods and a cylinder. The cylinder is fixedly connected to the inner wall of the groove, and the two slide rods are respectively fixedly connected to the inner wall of the slide groove and located directly below the extension groove. The ends of the two slide rods pass through the connecting plate and are slidably connected thereto. The output end of the cylinder is fixedly connected to the connecting plate.

[0010] Through the above technical solution, the slide rod passes through the connecting plate and slides with it, providing guidance for the movement of the connecting plate.

[0011] Preferably, the blocking mechanism includes a mounting plate and a blocking plate, the bottom of the mounting plate being fixedly connected to the top of the connecting arm, and the blocking plate being installed on the side of the mounting plate near the wheel limiting block.

[0012] The above technical solution enables the blocking plate to block the wheels.

[0013] Preferably, the wheel-stopping device further includes a pressure sensor, which is mounted on the mounting plate and the blocking plate and is used to detect the resistance when the mounting plate contacts the wheel.

[0014] With the above technical solution, if the vehicle is parked at a large angle, the rear wheels of the vehicle are not on the same straight line, making it difficult for one of the baffles to contact the rear wheels, and the pressure sensor on the baffle cannot detect the resistance.

[0015] Preferably, the storage groove is connected to the slide groove and the extension groove, the connecting plate extends into the storage groove, and the mounting plate and the blocking plate are located in the storage groove.

[0016] Through the above technical solution, the storage slot provides storage space for the blocking mechanism, making it flush with the surface of the vehicle platform, thus avoiding interference during vehicle movement.

[0017] Each of the inner walls of the storage slot is fixedly connected to a support platform, which is used to support the mounting plate that has been flipped into the storage slot.

[0018] Through the above technical solution, the support platform can provide support for the fallen mounting plate, disperse the pressure generated when the wheel runs over it, and reduce the direct impact on the torsion spring and the shaft.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The safety vehicle blocking device of this automated parking garage uses a cylinder to directly drive the connecting plate to move, which in turn drives the connecting arm and blocking mechanism. After the vehicle is parked on the vehicle platform, the entire vehicle blocking action can be completed simply by activating the cylinder. This eliminates the need for multiple steps and complex external control units, reducing operational steps, shortening vehicle blocking time, and improving parking efficiency.

[0021] 2. The support platform can provide support for the fallen mounting plate, disperse the pressure generated when the wheel runs over it, and reduce the direct impact on the torsion spring and shaft. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-3As shown, a safety vehicle-stopping device for a multi-level parking garage includes a vehicle-carrying plate 1. A wheel limiting block 6 is fixedly connected to the inner wall of the vehicle-carrying plate 1. A drive assembly and a connecting plate 8 are installed inside the vehicle-carrying plate 1. The drive assembly is used to move the connecting plate 8 and adjust the distance between the connecting plate 8 and the wheel limiting block 6. Both ends of the connecting plate 8 are rotatably connected to rotating shafts 11. One end of each rotating shaft 11 is fixedly connected to a connecting arm 13, and the other end of each rotating shaft 11 is fixedly connected to a limiting sleeve 14. Torsion springs 12 are fitted around the outer circumference of each rotating shaft 11. The top of the connecting arm 13 is fixedly... A blocking mechanism is fixedly connected to the vehicle carrier plate 1. A storage groove 4 is provided at the bottom of the inner wall of the vehicle carrier plate 1, and the blocking mechanism is located in the storage groove 4. One end of the torsion spring 12 is fixedly connected to the limiting sleeve 14, and the other end of the torsion spring 12 is fixedly connected to the connecting plate 8. Both ends of the connecting plate 8 are fixedly connected to the stop blocks 18. The stop blocks 18 are used to block and limit the connecting arm 13 when it is reset to the vertical position. The stop blocks 18 provide a mechanical hard limit for the vertical reset position of the connecting arm 13, ensuring that the blocking plate 17 can be stably maintained in a blocking state perpendicular to the surface of the vehicle carrier plate 1. The connecting plate 8 is moved by the drive component, and the distance between the connecting plate 8 and the wheel limiting block 6 is adjusted. The connecting arm 13 and the blocking mechanism are used to effectively block and position the vehicle, realizing automatic and effective blocking of the rear wheels of the vehicle and simplifying the parking blocking process.

[0030] like Figure 2 As shown, a groove 2 is formed at the bottom of the inner wall of the vehicle carrier plate 1. Slide grooves 3 are formed on both sides of the inner wall of the groove 2. An extension groove 5 is formed at the top of the inner wall of the slide groove 3, extending to the bottom of the inner wall of the vehicle carrier plate 1. The width of the extension groove 5 is greater than the width of the connecting arm 13, and it can accommodate the connecting arm 13 moving along the length of the vehicle carrier plate 1. The groove 2 provides installation space for the drive assembly and some connecting parts, the slide groove 3 provides installation space for the slide rod 9, and the extension groove 5 provides space for the movement of the connecting arm 13.

[0031] like Figure 2 As shown, the drive assembly includes two slide rods 9 and a cylinder 7. The cylinder 7 is fixedly connected to the inner wall of the groove 2, and the two slide rods 9 are respectively fixedly connected to the inner wall of the slide groove 3 and located directly below the extension groove 5. The ends of the two slide rods 9 pass through the connecting plate 8 and are slidably connected thereto. The output end of the cylinder 7 is fixedly connected to the connecting plate 8. The slide rods 9 passing through the connecting plate 8 and being slidably connected thereto provide guidance for the movement of the connecting plate 8.

[0032] like Figure 3 As shown, the blocking mechanism includes a mounting plate 15 and a blocking plate 17. The bottom of the mounting plate 15 is fixedly connected to the top of the connecting arm 13, and the blocking plate 17 is installed on the side of the mounting plate 15 near the wheel limiting block 6. The blocking plate 17 can block the wheel.

[0033] like Figure 4As shown, the vehicle-stopping device also includes a pressure sensor 16, which is mounted on the mounting plate 15 and the blocking plate 17 and is used to detect the resistance when the mounting plate 15 contacts the wheel. If the vehicle is parked at a large angle, the rear wheels of the vehicle are not on the same straight line, making it difficult for one of the blocking plates 17 to contact the rear wheel, and the pressure sensor 16 on the blocking plate 17 cannot detect the resistance.

[0034] Pressure sensor 16 is disposed between mounting plate 15 and baffle plate 17 to detect pressure signal when baffle plate 17 is squeezed by tire.

[0035] Under normal circumstances, when the baffle 17 moves behind the rear wheel of the vehicle, it will come into contact with the tire. The pressure sensor 16 will detect a small pressure value, and the system will determine that the vehicle has been successfully stopped.

[0036] In an abnormal situation, the vehicle is placed at an angle, causing one of the barriers 17 to fail to contact the rear wheels. In this case, the barrier 17 on that side will not encounter tire resistance during movement, and the pressure sensor 16 on it will not output a valid signal. After receiving this signal, the control system can determine that the vehicle is parked abnormally and trigger an alarm or stop the garage operation to prompt the driver to re-park the vehicle.

[0037] It should be noted that the above-mentioned control system, which makes logical judgments based on sensor signals and controls the actions of actuators (such as cylinders), has hardware components (such as PLCs and controllers) and programming methods that are existing technologies in the field of automation. Those skilled in the art can perform conventional design and implementation based on this functional description.

[0038] like Figure 2 As shown, the storage slot 4 is connected to the slide 3 and the extension slot 5, the connecting plate 8 extends into the storage slot 4, and the mounting plate 15 and the blocking plate 17 are located in the storage slot 4. The storage slot 4 provides storage space for the blocking mechanism, making it flush with the surface of the vehicle platform 1, thus avoiding interference during vehicle operation.

[0039] like Figure 2 As shown, the inner wall of the storage groove 4 is fixedly connected to the support platform 10, which is used to support the mounting plate 15 that has been flipped into the storage groove 4. The support platform 10 can provide support for the mounting plate 15 in the fallen state, disperse the pressure generated when the wheel runs over it, and reduce the direct impact on the torsion spring 12 and the rotating shaft 11.

[0040] When the vehicle enters the vehicle platform 1, the front wheels first contact the blocking plate 17. Under the pressure of the wheels, the blocking plate 17 overcomes the torque of the torsion spring 12 and flips down into the storage slot 4 around the pivot 11 via the connecting arm 13. The support platform 10 supports the fallen mounting plate 15, and the vehicle passes smoothly.

[0041] The vehicle continues to move forward until the front wheels contact and abut against the wheel limiting block 6, achieving initial positioning. At this point, the rear wheels are positioned between the blocking plate 17 and the wheel limiting block 6.

[0042] After the vehicle passes over it, due to the restoring torque of the torsion spring 12, the connecting arm 13 will cause the blocking plate 17 to flip in the opposite direction until the bottom of the connecting arm 13 contacts the stop block 18 on the connecting plate 8. The stop block 18 forms a mechanical limit on the connecting arm 13, so that the blocking plate 17 is reset to a blocking state perpendicular to the surface of the vehicle plate 1.

[0043] Cylinder 7 drives connecting plate 8 to slide along the inner wall of slide groove 3, adjusting the distance between blocking plate 17 and wheel limit block 6. When connecting plate 8 moves, it drives the entire blocking mechanism to move, so that blocking plate 17 moves behind the rear wheel and squeezes the rear wheel to prevent the vehicle from rolling backward.

[0044] When retrieving the vehicle, the output end of cylinder 7 extends outward, causing the connecting plate 8 to move away from the wheel limit block 6. At this time, the vehicle carrier plate 1 presses against the connecting arm 13, causing the mounting plate 15 to flip and fall into the storage slot 4.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
