Description

Technical Field

[0001] This utility model relates to the field of automated parking system technology, specifically to an anti-fall device for automated parking systems. Background Technology

[0002] A device that prevents a transporter or vehicle platform from falling when it is in a static position in the air after it has moved into place is called a static fall arrestor. In contrast, there is a dynamic fall arrestor, which is a device that prevents a transporter or vehicle platform from falling during its movement. Different types of parking equipment and different operating methods of parking equipment have different requirements for the fall arrest performance of multi-level parking garages.

[0003] Most of the devices on the market have complex structures, are difficult to maintain, and have insufficient reliability. Electromagnetic devices are expensive to operate and maintain, and have poor reliability. Mechanical and electromagnetic devices are also complex in structure, making maintenance difficult and costly.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN111395842A, application date: 2020-04-25) discloses a multi-level parking garage anti-fall device, including a car carrier plate, a lifting frame fixedly mounted on the top end of the car carrier plate, a side column connected to the end of the lifting frame, and a device base fixedly connected to the bottom end of the car carrier plate. A brake gear, an intermediate gear, and a generator gear are rotatably connected inside the device base. The side column has meshing teeth that mesh with the brake gear. The brake gear, intermediate gear, and generator gear are sequentially meshed. A generator is fixedly mounted inside the device base. The drive shaft of the generator is coaxially fixedly connected to the generator gear. A braking device is provided outside the brake gear. The braking device is connected to a controller. A wire is connected between the controller and the generator. By setting a braking device, the present invention can drive the generator to generate electricity when the car carrier plate falls, and lock and stop the fall, thereby effectively improving the safety of the multi-level parking garage.

[0005] While existing designs can solve the above problems, they require too much manual operation and lack intelligence when stable vehicle operation is needed. Furthermore, they involve many manual steps and are not very convenient to use. Moreover, they are not time-saving enough when driving the vehicle away. Utility Model Content

[0006] The purpose of this utility model is to provide a fall prevention device for a three-dimensional parking garage, so as to solve the problems mentioned in the background art, such as excessive manual operation and insufficient intelligence when stabilizing vehicles, the lack of convenience due to the large number of manual steps during use, and the lack of time-saving when driving away vehicles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional parking garage anti-fall device, comprising a vehicle mounting base installed inside the moving track, and external moving grooves installed on both sides of the vehicle mounting base. A transmission worm is installed inside the external moving groove, and a meshing transmission mechanism for sliding a second tire limiting block left and right is installed on the outer surface of the transmission worm. The meshing transmission mechanism includes a tire rotating shaft, which is rotatably installed inside the vehicle mounting base. A transmission belt is installed on the outer surface of the end of the tire rotating shaft, and a transmission worm is installed at the other end of the inner surface of the transmission belt. The front end of the transmission worm is rotatably installed inside the vehicle mounting base, and the other end of the transmission worm is rotatably installed inside the external moving groove. An interlocking groove is formed on the upper surface of the vehicle mounting base, and an elastic nesting mechanism for fixing a semi-circular interlocking rod is installed inside the interlocking groove.

[0008] Furthermore, the elastic nesting mechanism includes a fixed rotating rod, which is fixedly installed inside the interlocking groove. An L-shaped swing plate is installed on the outer surface of the fixed rotating rod. The L-shaped swing plate is designed in an L-shape and is rotatably installed on the outer surface of the fixed rotating rod. Semi-circular interlocking rods are installed at both ends of the lower surface of the L-shaped swing plate, and a sliding abutment frame is installed at the bottom of the inner surface of the interlocking groove.

[0009] Furthermore, a transmission contact plate is installed inside the sliding contact frame, and the transmission contact plate passes through the interior of the sliding contact frame. A support spring is installed on the outer surface of the transmission contact plate, and the top of the support spring abuts against the outer surface of the sliding contact frame. A serial fitting frame is installed at the front end of the transmission contact plate, and the serial fitting frame has a U-shaped design.

[0010] Furthermore, a meshing gear rack is installed above the transmission worm gear, and a first tire limiting block and a second tire limiting block are installed above the meshing gear rack. The meshing gear rack, the first tire limiting block, and the second tire limiting block are integrated into one piece, and a sliding inner groove is provided on the upper surface of the vehicle mounting base.

[0011] Furthermore, the first tire limiting block and the second tire limiting block slide along the inner track of the sliding groove, and two sets of meshing gear racks are symmetrically installed with respect to the center point of the vehicle mounting base about the left and right. Moreover, the outer surface of the transmission worm gear contacts the lower surface of the meshing gear rack to form a meshing structure.

[0012] Furthermore, the tire rotating shaft forms a transmission structure by contacting the inner surface of the transmission belt with the outer surface of the transmission worm, and the inner surface of the moving track forms a sliding structure by contacting the side of the vehicle mounting base, and the outer surface of the tire rotating shaft forms a sliding structure by contacting the inner surface of the transmission belt.

[0013] Furthermore, the rotation trajectory of the semi-circular fitting rod passes through the interior of the serial fitting frame, and the front end of the serial fitting frame is nested inside the vehicle mounting base. A fixed traction rod is installed on the side of the transmission contact plate, and the fixed traction rod and the transmission contact plate are designed as an integral unit.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the tire fixing operation of the vehicle needs to be performed, the vehicle is first driven into the vehicle mounting base. As the movement continues, the wheel contacts the tire rotating shaft and drives it. The rotation of the tire rotating shaft drives the transmission worm gear to rotate in a circle through the transmission belt. As the transmission worm gear rotates, it meshes with the gear rack and drives the first tire limiting block and the second tire limiting block forward, and gradually approaches the front and rear sides of the wheel. Finally, the wheel rotation stops after ensuring that the front and rear of the tire are nested and stable. This design ensures that even if the vehicle slips, there will be no risk of falling.

[0015] Furthermore, when the vehicle drives onto the vehicle mounting base, the front of the vehicle will first contact the L-shaped swing plate and move forward, pushing it along the fixed rotating rod to the inner groove of the fitting dock. At the same time, the semi-circular fitting rod will swing downward and contact the transmission contact plate. Since the semi-circular fitting rod is designed to be semi-circular, the transmission contact plate is resisted and slides along the sliding contact frame. After passing through the transmission contact plate, the support spring pushes it out again to complete the fixation of the semi-circular fitting rod. As the front end of the L-shaped swing plate is fixed, the rear end is gradually raised and fixed at 90 degrees. Adding the car stop soft plate can complete the fixation of the rear of the vehicle.

[0016] Furthermore, when it is necessary to open the L-shaped swing plate to drive out of the vehicle mounting base, simply pull the fixed traction rod left and right to disengage the semi-circular interlocking rod from its nested installation. The vehicle can then be driven out directly through the L-shaped swing plate after removing the barrier plate. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a three-dimensional parking garage anti-fall device, including a vehicle mounting base 2 installed inside a moving track 1, and external moving grooves 13 installed on both sides of the vehicle mounting base 2. A transmission worm 7 is installed inside the external moving groove 13, and a meshing transmission mechanism for sliding the second tire limiting block 10 left and right is installed on the outer surface of the transmission worm 7. The meshing transmission mechanism includes a tire rotating shaft 5, which is rotatably installed inside the vehicle mounting base 2. A transmission belt 6 is installed on the outer surface of the end of the tire rotating shaft 5, and a transmission worm 7 is installed at the other end of the inner surface of the transmission belt 6. The front end of the transmission worm 7 is rotatably installed inside the vehicle mounting base 2, and the other end of the transmission worm 7 is rotatably installed inside the external moving groove 13. An interlocking groove 14 is opened on the upper surface of the vehicle mounting base 2, and an elastic nesting mechanism for fixing a semi-circular interlocking rod 19 is installed inside the interlocking groove 14.

[0026] like Figure 2 , Figure 3 , Figure 4The technical solution shown, in order to solve the problem of vehicle tire slippage and difficulty in fixing, discloses the following: a meshing gear rack 8 is installed above the transmission worm gear 7, and a first tire limiting block 9 and a second tire limiting block 10 are installed above the meshing gear rack 8. The meshing gear rack 8, the first tire limiting block 9, and the second tire limiting block 10 are integrated into one piece. Furthermore, a sliding inner groove 11 is formed on the upper surface of the vehicle mounting base 2, and the first tire limiting block 9 and the second tire limiting block 10 slide along the trajectory inside the sliding inner groove 11. Furthermore, two sets of meshing gear rack 8, first tire limiting block 9, and second tire limiting block 10 are symmetrically installed about the center point of vehicle mounting base 2. Moreover, the outer surface of transmission worm 7 contacts the lower surface of meshing gear rack 8 to form a meshing structure. The tire rotating shaft 5 contacts the outer surface of transmission worm 7 through the inner surface of transmission belt 6 to form a transmission structure. The inner surface of moving track 1 contacts the side of vehicle mounting base 2 to form a sliding structure. Moreover, the outer surface of tire rotating shaft 5 contacts the inner surface of transmission belt 6 to form a sliding structure.

[0027] When it is necessary to limit and fix the vehicle tires, the driver first drives the vehicle onto the vehicle mounting base 2. As the vehicle moves, the front wheels first contact the tire rotating shaft 5. Since the tire rotating shaft 5 is rotatably installed inside the vehicle mounting base 2, when the tire contacts the tire rotating shaft 5, it will cause the tire to rotate in a circle, and the wheel will also rotate in place without moving forward. When the tire rotating shaft 5 rotates, it will drive the transmission worm gear 7, which is nested on the other end of the inner surface, to rotate through the externally nested transmission belt 6. The two ends of the transmission worm gear 7 are respectively rotatably installed inside the vehicle mounting base 2 and on the external moving groove 13. Inside the worm gear 7, when it is driven to rotate in a circular motion, it will drive the meshing gear rack 8 that is in contact with it to generate a meshing motion. Since the upper end of the meshing gear rack 8 is equipped with a first tire limiting block 9 and a second tire limiting block 10 on the front and rear sides of the wheel respectively, as the meshing gear rack 8 slides forward along the sliding inner groove 11 under the meshing motion, the first tire limiting block 9 and the second tire limiting block 10 fixed on the upper end are also driven to slide and limit the wheel to the front and rear ends. When the first tire limiting block 9 and the second tire limiting block 10 reach the appropriate fixed position, the wheel stops rotating, thus realizing the limiting operation of the wheel.

[0028] like Figure 1 , Figure 5 , Figure 6The technical solution shown, in order to solve the problem of the vehicle being difficult to fix when tilting backward, discloses the following: An elastic nesting mechanism includes a fixed rotating rod 3, which is fixedly installed inside the fitting and docking inner groove 14. An L-shaped swing plate 4 is installed on the outer surface of the fixed rotating rod 3. The L-shaped swing plate 4 is L-shaped and rotatably installed on the outer surface of the fixed rotating rod 3. Semi-circular fitting rods 19 are installed at both ends of the lower surface of the L-shaped swing plate 4. A sliding contact frame 15 is installed at the bottom of the inner surface of the fitting and docking inner groove 14. A transmission contact plate 1 is installed inside the sliding contact frame 15. 6. The transmission contact plate 16 passes through the interior of the sliding contact frame 15. A support spring 17 is installed on the outer surface of the transmission contact plate 16, and the top of the support spring 17 abuts against the outer surface of the sliding contact frame 15. A series fitting frame 18 is installed at the front end of the transmission contact plate 16. The series fitting frame 18 is U-shaped. The rotation trajectory of the semi-circular fitting rod 19 passes through the interior of the series fitting frame 18. The front end of the series fitting frame 18 is nested inside the vehicle mounting base 2. A fixed traction rod 12 is installed on the side of the transmission contact plate 16. The fixed traction rod 12 and the transmission contact plate 16 are integrated into one piece.

[0029] When the vehicle drives onto the vehicle mounting base 2, the front of the vehicle first contacts the L-shaped swing plate 4. Since the L-shaped swing plate 4 is rotatably mounted outside the fixed rotating rod 3, and the fixed rotating rod 3 is fixedly mounted inside the fitting groove 14 opened above the vehicle mounting base 2, the L-shaped swing plate 4 rotates along the fixed rotating rod 3 into the fitting groove 14 after being pushed by the front of the vehicle. When the L-shaped swing plate 4 rotates, the semi-circular fitting rod 19, fixedly mounted on the lower surface of the rotating surface, rotates synchronously, and the rotation trajectory of the semi-circular fitting rod 19 contacts the transmission contact plate 16. Because the lower end of the semi-circular fitting rod 19 is semi-circular, the semi-circular fitting rod 19 pushes the transmission contact plate 16 outwards, causing the transmission contact plate 16 to be pushed. After contact, it will slide outward along the sliding abutment frame 15 fixedly installed inside the vehicle mounting base 2. During the sliding process, the support spring 17 nested on the outer surface will contact the sliding abutment frame 15 and compress and contract. When the semi-circular fitting rod 19 passes through the transmission abutment plate 16 and enters the serial fitting frame 18 fixedly installed at the front end of the transmission abutment plate 16, the semi-circular fitting rod 19 will disengage from the transmission abutment plate 16, and at the same time, the support spring 17 will release elastic potential energy to push the transmission abutment plate 16 out again. The transmission abutment plate 16 and the serial fitting frame 18 will complete the overall nesting and fixing of the semi-circular fitting rod 19. Since the end of the L-shaped swing plate 4 is fixed, the front end will rotate 90 degrees and rise. At this time, a special car stop pad can be used to prevent the vehicle from sliding backward and falling.
