[0002] With the increasing number of cars on the road, the problem of insufficient parking space has become increasingly apparent, leading to the widespread application of mechanical parking equipment, especially lift-and-slide type mechanical parking equipment. Lift-and-slide type mechanical parking equipment requires lifting and lowering of the vehicle platform, in addition to the entry and exit levels. When a vehicle is raised on the lift platform, if the platform malfunctions or the lifting is unstable, the car may fall. Furthermore, the chains or steel cables used to secure the platform may break, posing a significant challenge to protecting the car in the event of an accident. Utility Model Content
[0003] The purpose of this utility model is to provide a mechanical parking equipment anti-fall protection device with a simple structure. It is not easy for the vehicle to slip after it is parked in the designated position. In the event of an accident on the lifting platform, it can absorb the impact of the car falling. It has high protection capability, strong practicality, and is suitable for promotion.
[0004] This utility model provides the following technical solution: a mechanical parking equipment anti-fall protection device, including a main board, the main board is installed on a lifting platform, a recessed wheel groove is fixedly provided in the middle of the main board, a drive seat is fixedly provided below the wheel groove on the main board, and a card seat is provided on the front and rear sides of the main board on the wheel groove, with the main board passing through the bottom of the card seat;
[0005] The drive seat has symmetrical arc-shaped guide rails on both sides inside. A pusher frame is slidably installed inside the arc-shaped guide rails. The pusher frame extends to the card seat and is fixedly provided with a friction pad. An extension plate is fixedly provided at one end of the pusher frame inside the drive seat.
[0006] An electric telescopic rod is fixedly installed at the drive seat corresponding to the extension plate. The output end of the electric telescopic rod is slidably connected to the extension plate through a clamping mechanism. A pressure sensor is installed at the bottom of the wheel groove, and the power signal of the pressure sensor is connected to the electric telescopic rod.
[0007] Preferably, side plates are fixedly provided on the left and right sides of the wheel groove below the main board, and an impact plate is provided below the side plates. A symmetrical buffer spring is fixed between the impact plate and the main board. A cutting plate is fixedly provided on the impact plate corresponding to the side plate. The cutting plate is slidably connected to the inner side of the side plate through a sliding groove. An array of energy-absorbing bolts is threadedly connected to the side plate. The studs of the energy-absorbing bolts pass through the side plate and are located above the cutting plate.
[0008] Preferably, the pusher is a semi-circular rod with a diameter sufficient to extend out of the main board and push the friction pad to the wheel hub and tire, and the pushing force of the electric telescopic rod is fixed.
[0009] Preferably, a clamping seat is fixedly provided at the output rod of the electric telescopic rod, and the top end of the extension plate is inserted into the clamping groove of the clamping seat and slidably connected thereto.
[0010] The beneficial effects of this utility model are: simple structure, less prone to slippage after the vehicle is parked in the designated position, and able to absorb the impact of the car falling in the event of an accident on the lifting platform, providing high protection capability and strong practicality, as detailed below:
[0011] (1) This utility model is equipped with a pusher frame. When the vehicle's tire enters the wheel groove, the pressure sensor senses that the vehicle has stopped. At this time, the two electric telescopic rods connected to the electric signal operate and push their corresponding extension plates forward. The arc-shaped pusher frame is pushed out. During this process, the extension plates move downward in the clamping seat with the curvature of the guide rail. The friction pad moves with the pusher frame. Due to the curvature of the pusher frame, it deflects towards the tire and presses against the wheel hub and tire under the push of the electric telescopic rods, clamping the tire from both sides. Through the clamping mechanism and the wheel groove, the vehicle can be prevented from falling when the lifting platform tilts.
[0012] (2) This utility model is equipped with an impact plate. If the lifting platform falls, the impact plate will first contact the ground. At this time, the buffer spring provides buffering. The cutting plate rises along the slide rail. When it rises, it contacts the stud of the energy-absorbing bolt at the top. When the stud of the energy-absorbing bolt is broken, it absorbs the kinetic energy when the vehicle falls, reduces the impact force when the vehicle falls, and thus protects the vehicle.

[0021] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] See Figure 1-2A fall protection device for mechanical parking equipment includes a main board 1, which is mounted on a lifting platform. A recessed wheel groove 2 is fixedly provided in the center of the main board 1, with the wheel located at the groove 2. A drive seat 3 is fixedly provided below the wheel groove 2 on the main board 1, driving the wheel clamping area via the drive seat 3. Card slots 14 are provided on the front and rear sides of the main board 1 at the wheel groove 2, for placing friction pads 5. The main board 1 extends through the lower part of the card slots 14. Symmetrical arc-shaped guide rails 12 are provided on both sides inside the drive seat 3. A pusher 4 slides within the arc-shaped guide rails 12, extending to the card slots 14 and fixing the friction pads 5 thereon. The pusher 4 is a semi-circular rod with a diameter sufficient to extend out of the main board 1 and push the friction pads 5. When the pusher 4 is pushed along the guide rail to the wheel hub tire, the friction pad 5 deflects relative to the card seat 14 and presses against the force-bearing part of the wheel. An extension plate 15 is fixedly installed at one end of the pusher 4 inside the drive seat 3. An electric telescopic rod 13 is fixedly installed at the drive seat 3 corresponding to the extension plate 15. The output end of the electric telescopic rod 13 is slidably connected to the extension plate 15 through a clamping mechanism. The pusher 4 is pushed forward by the electric telescopic rod 13. A pressure sensor 6 is installed at the bottom of the wheel groove 2. The power signal of the pressure sensor 6 is connected to the electric telescopic rod 13. After the pressure sensor 6 detects the pressure, the electric telescopic rod 13 operates. The pushing force of the electric telescopic rod 13 is fixed, so that the friction pad 5 maintains pressure.
[0023] See Figure 3 A clamping seat 17 is fixedly provided at the output rod 16 on the electric telescopic rod 13. The top end of the extension plate 15 is inserted into the clamping groove of the clamping seat 17 and slidably connected thereto. When the arc-shaped push frame 4 is pushed out or pulled back, the extension plate 15 moves up and down in the clamping seat 17 with the arc of the guide rail.
[0024] See Figure 1 Side plates 7 are fixedly installed on the left and right sides of the wheel groove 2 below the main board 1. An impact plate 8 is installed below the side plate 7. A symmetrical buffer spring 10 is fixed between the impact plate 8 and the main board 1. When the lifting platform falls, the impact plate 8 contacts the ground first. At this time, the buffer spring 10 provides buffering. A cutting plate 9 is fixedly installed on the impact plate 8 corresponding to the side plate 7. The cutting plate 9 is slidably connected to the inner side of the side plate 7 through a slide groove. An array of energy-absorbing bolts 11 are connected to the side plate 7 by threads. The studs of the energy-absorbing bolts 11 penetrate through the side plate 7 and are located above the cutting plate 9. The cutting plate 9 rises along the slide rail. When the studs of the energy-absorbing bolts 11 are crushed, they absorb kinetic energy.
[0025] This utility model relates to a mechanical parking equipment anti-fall protection device with a simple structure. It is not easy for the vehicle to slip after it is parked in the designated position. In the event of an accident on the lifting platform, it can absorb the impact of the car falling. It has high protection capability, strong practicality, and is suitable for widespread application.
[0026] For specific usage, please refer to... Figure 1-3When the vehicle's tires enter the wheel groove 2, the pressure sensor 6 senses that the vehicle has stopped. At this time, the two electric telescopic rods 13 connected to them by electrical signals operate, pushing their corresponding extension plates 15 forward. The arc-shaped push frame 4 is pushed out. During this process, the extension plates 15 move downward in the clamping seat 17 along the arc of the guide rail. The friction pad 5 moves with the push frame 4. Due to the arc of the push frame 4, it deflects towards the tire and presses against the wheel hub and tire under the push of the electric telescopic rods 13, clamping the tire from both sides. Through the clamping mechanism and the wheel groove 2, the vehicle is prevented from falling when the lifting platform tilts.
[0027] Reference Figure 1 If the lifting platform falls, the impact plate 8 will first contact the ground. At this time, the buffer spring 10 will provide cushioning. The cutting plate 9 will rise along the slide rail. When it rises, it will contact the stud of the energy-absorbing bolt 11. When the stud of the energy-absorbing bolt 11 is broken, it will absorb the kinetic energy of the vehicle falling and protect the vehicle.
