Description

Technical Field

[0001] This invention belongs to the field of automated parking garage technology, and particularly relates to a parking rack device for automated parking garages. Background Technology

[0002] With economic development, the number of cars in cities has increased rapidly, leading to increasingly prominent parking problems. Currently, the construction of multi-level parking garages can effectively solve the problem of parking space shortages and greatly improve space utilization.

[0003] According to Chinese patent application CN110056221U for a three-dimensional parking garage, the patent includes a parking rack, a frame, and a lifting assembly. The frame includes a column and a rotating arm assembly. One end of the lifting assembly is mounted on the parking rack. By extending and retracting the other end of the lifting assembly relative to the first end, the other end of the lifting assembly is supported on the ground, thereby pushing the parking rack off the ground. One end of the rotating arm assembly is hinged to the parking rack, and the other end is hinged to the column. While the lifting assembly pushes the parking rack off the ground, the rotating arm assembly pulls the parking rack towards the column, allowing the vehicle to be parked on the parking rack. Because the lifting assembly acts directly on the parking rack, it can effectively distribute the weight of the parking rack and the vehicle, effectively reducing or avoiding deformation of the rotating arm assembly due to excessive weight, thus effectively ensuring the stability of the parking rack during the lifting process.

[0004] Currently, multi-level parking garages can solve the parking problem for multiple vehicles for families. However, with existing parking rack systems, users often face the risk of collisions when parking in their own multi-level parking garages due to the lack of guidance and assistance. This not only damages the equipment but also affects the safety of the drivers, especially for novice drivers where parking safety is paramount. Therefore, we have designed a parking rack system for multi-level parking garages. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a parking rack device for multi-level parking garages. This parking rack device solves the technical problem that when users of existing parking rack devices park in their own multi-level parking garages, due to the lack of guidance and assistance, drivers entering the parking area are prone to collisions, which damages the equipment and affects the safety of the drivers.

[0006] To achieve the above objectives, an embodiment of the first aspect of the present invention provides a parking rack device for a multi-level parking garage, comprising a multi-level parking garage, bases vertically arranged at the four corners of the multi-level parking garage, sliding seats disposed in each base, and lifting parking plates disposed in the multi-level parking garage and connected to each sliding seat;

[0007] It also includes protective devices, which include guardrails connected to both sides of the lifting parking platform, several mounting rods set in each guardrail, rubber protective rollers for vehicle guidance and protection set at the end of each mounting rod, and protective rubber pads set on the inner wall of the multi-level parking garage.

[0008] A further improvement is that the protective device also includes a base connected to the bottom surface of the lifting parking platform, several mounting blocks rotatably mounted on the side of the base, and a telescopic protective rod connected to each mounting block. Two receiving slots are provided on both sides of the bottom surface of the three-dimensional parking garage, and the bottom surface of the telescopic protective rod is rotatably mounted in the receiving slot.

[0009] The telescopic protective rod is composed of several interlocking rubber cylinders, with the outer diameter of each rubber cylinder increasing in the telescopic direction.

[0010] A further improvement is that the device also includes a wheel limiting mechanism, which includes two front wheel stops on one side of the lifting parking plate, a pedal rotatably mounted on the lifting parking plate and corresponding to each front wheel stop, a mounting cavity in the base, two levers in the mounting cavity, a pressure rod rotatably mounted on the same side of each lever and rotatably connected to the bottom surface of the pedal, a mounting cylinder in the mounting cavity, a return spring connected to each mounting cylinder, and a lower pressure column in the mounting cylinder and rotatably connected to one end of the lever.

[0011] A further improvement is that the lifting parking plate is provided with a groove for installing a pedal.

[0012] A further improvement is that an extension slot is provided on the other side of the lifting parking platform, and a rear wheel stop is slidably installed in each extension slot. The bottom surface of each rear wheel stop is rotatably connected to the ends of two levers. An inflatable compression pad is provided on the side of each rear wheel stop, and an inflatable compression pad is provided with an air inlet on each inflatable compression pad. During installation, the air pipe of an external electric air pump is connected to the air inlet, and sufficient air is injected into the inflatable compression pad to compress and limit the rear wheels of the vehicle, preventing the vehicle from rolling backward and causing an accident.

[0013] A further improvement is that each of the mounting rods is connected to a mounting base at its end, each mounting base has a mounting groove inside, each mounting groove has a universal ball joint inside, each mounting base has a through notch on its top surface, a fastening cover plate is installed in the notch, a pressure sensing switch is installed in each fastening cover plate and on the rubber cylinder, and a connecting rod is installed on the top of each rubber protective roller, with each connecting rod connected to each universal ball joint.

[0014] A further improvement is that a through groove is provided on the bottom surface of each mounting base, each connecting rod is respectively provided in the through groove, and a number of buffer springs are provided in each through groove in a circular distribution, and each buffer spring is respectively connected to the connecting rod.

[0015] A further improvement is that the device also includes a power structure, which includes a lifting hydraulic cylinder connected to each base, a sprocket rotating at the extension end of each lifting hydraulic cylinder, and lifting chains connected to the bottom surface of each base and resting on the sprocket. The ends of the four lifting chains are respectively connected to a sliding seat.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) In this invention, after the user selects to park the vehicle in the upper parking space of the multi-level parking garage, when the vehicle touches it, the rubber protective roller swings and touches the pressure sensing switch. At this time, the pressure sensing switch activates the alarm flashing light to provide an alarm warning to the user until the vehicle is completely parked. The rubber protective roller can protect the vehicle body and effectively prevent the vehicle from being scratched. After the user's vehicle is parked, the two front wheels of the vehicle drive into the front wheel seats respectively. The two front wheels press the pedals where they are located, causing the height of one end of the pressure lever under each pedal to drop. At this point, the lower pressure column at the bottom of the lever compresses the return spring inside the mounting cylinder, causing the return spring to deform and generate a rebound force. Meanwhile, the other end of the lever lifts up, extending the two rear wheel stops along with the inflatable compression pads from the extension slots of the lifting parking platform. This allows an external electric air pump to inject sufficient air into the inflatable compression pads, which is then used to compress and limit the rear wheels of the vehicle, preventing the vehicle from rolling backward and causing an accident, thus improving safety. When the user retrieves the vehicle, the above operation is repeated, and under the action of the return spring's rebound force, the rear wheel stops along with the inflatable compression pads retract into the extension slots.

[0018] (2) In this invention, when a user parks their vehicle in the lower level of the multi-level parking garage, four lifting hydraulic cylinders are simultaneously activated to provide power for the drive, causing each sprocket to drive the lifting chain to pull the lifting parking platform up and down. At this time, the mounting blocks and telescopic guardrails located on both sides of the lifting parking platform rotate. Since the telescopic guardrail is composed of several sections of rubber cylinders that are nested together, each section of the telescopic guardrail is pulled out as the lifting parking platform moves. When a vehicle touches the guardrail, the rubber cylinders touch the pressure sensor switch and are activated. The pressure sensor switch then activates the alarm flashing light to provide a warning to the user until the vehicle is completely parked. The multiple sections of rubber cylinders also protect the vehicle body, effectively preventing scratches and achieving double-layer parking space protection. Attached Figure Description

[0029] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1As shown, a parking rack device for a multi-level parking garage includes a multi-level parking garage 1, bases 14 vertically arranged at the four corners of the multi-level parking garage 1, sliding seats 12 arranged in each base 14, lifting parking plates 11 arranged in the multi-level parking garage 1 and connected to each sliding seat 12, and a power structure 13. The power structure 13 includes lifting hydraulic cylinders 131 connected in each base 14, sprockets 132 rotating at the extension end of each lifting hydraulic cylinder 131, and lifting chains 133 connected to the bottom surface of each base 14 and resting on the sprockets 132. The ends of the four lifting chains 133 are respectively connected to the sliding seats 12. By synchronously starting the four lifting hydraulic cylinders 131 to provide power for driving, each sprocket 132 drives the lifting chains 133 to pull the lifting parking plates 11 to rise and fall.

[0032] like Figure 2 As shown, it also includes a protective device 2, which includes a protective railing 21 connected to both sides of the lifting parking platform 11, a number of mounting rods 22 set in each protective railing 21, a rubber protective roller 23 for vehicle guidance and protection set at the end of each mounting rod 22, and a protective rubber pad 24 set on the inner wall of the three-dimensional parking garage 1.

[0033] like Figure 2 and Figure 5 As shown, the protective device 2 also includes a base 25 connected to the bottom surface of the lifting parking platform 11, several mounting blocks 251 rotatably mounted on the sides of the base 25, and telescopic protective rods 252 connected to each mounting block 251. Two receiving slots 253 are provided on both sides of the bottom surface of the multi-level parking garage 1, and the bottom surface of the telescopic protective rods 252 is rotatably mounted in the receiving slots 253. The telescopic protective rods 252 are divided into several sections of rubber cylinders 254 that are nested together. The outer diameter of each section of rubber cylinder 254 increases in the telescopic direction. Power is provided by the power structure 13, and the mounting blocks 251 and the telescopic protective rods 252 located on both sides of the lifting parking platform 11 rotate. Since the telescopic protective rods 252 are divided into several sections of rubber cylinders 254 that are nested together, each section of rubber cylinder 254 of the telescopic protective rods 252 is pulled out as the lifting parking platform 11 is lifted. When the vehicle is touched, the rubber cylinder 254 contacts the pressure sensing switch 27 and is activated. The pressure sensing switch 27 then activates the alarm flashing light to provide a warning to the user until the vehicle comes to a complete stop. The multiple rubber cylinders 254 are used to protect the vehicle body.

[0034] like Figure 4As shown, each mounting rod 22 is connected to a mounting base 26 at its end. Each mounting base 26 has a mounting groove 261 inside, and a universal ball joint 262 inside each mounting groove 261. A notch 263 is provided through the top surface of each mounting base 26, and a fastening cover plate 264 is provided inside the notch 263. A pressure sensing switch 27 is provided inside each fastening cover plate 264 and on the rubber cylinder 254. A connecting rod 265 is provided at the top of each rubber protective roller 23, and each connecting rod 265 is connected to each universal ball joint 262. The bottom surface of each mounting base 26 is through... A through groove 266 is provided, and each connecting rod 265 is respectively located in the through groove 266. Several buffer springs 267 are arranged in a circular pattern in each through groove 266, and each buffer spring 267 is connected to the connecting rod 265. When the vehicle touches it, the rubber protective roller 23 swings and touches the pressure sensing switch 27. At this time, the pressure sensing switch 27 activates the alarm flashing light to provide an alarm warning and give the user a certain reminder until the vehicle comes to a complete stop. The rubber protective roller 23 can protect the vehicle body and effectively prevent the vehicle from being scratched.

[0035] Example 2

[0036] like Figure 3 As shown, based on Embodiment 1, the device further includes a wheel limiting mechanism 3. The wheel limiting mechanism 3 includes two front wheel stops 31 disposed on one side of the lifting parking plate 11, a pedal 32 rotatably disposed on the lifting parking plate 11 and corresponding to each front wheel stop 31, a mounting cavity 33 disposed in the base 25, two levers 34 disposed in the mounting cavity 33, a pressure rod 37 rotatably disposed on the same side of each lever 34 and rotatably connected to the bottom surface of the pedal 32, a mounting cylinder 35 disposed in the mounting cavity 33, a return spring 36 connected in each mounting cylinder 35, and a lower pressure column 310 disposed in the mounting cylinder 35 and rotatably connected to one end of the lever 34. The lifting parking plate 11 is provided with a groove 111 for mounting the pedal 32, which is used to mount one side of the pedal 32 in the groove 111 through a rotating shaft. When the front wheels of the vehicle press the pedal 32, the pedal 32 rotates, and the pedal 32 drives the pressure rod 37 to move downward until the pedal 32 rotates to parallel.

[0037] After the user's vehicle is parked, the two front wheels of the vehicle drive into the front wheel stops 31 respectively. The two front wheels press down on the pedals 32, causing the pressure rods 37 under each pedal 32 to press down on one end of the lever 34. At this time, the lower pressure column 310 at the bottom of the lever 34 compresses the return spring 36 in the mounting cylinder 35, causing the return spring 36 to deform and generate a rebound force. Meanwhile, the other end of the lever 34 is raised, and the two rear wheel stops 38, together with the inflatable compression pads 39, extend out of the extension slots 112 of the lifting parking plate 11.

[0038] like Figure 3As shown, an extension slot 112 is provided on the other side of the lifting parking platform 11. A rear wheel stop 38 is slidably installed in each extension slot 112. The bottom surface of each rear wheel stop 38 is rotatably connected to the ends of two levers 34. An inflatable compression pad 39 is provided on the side of each rear wheel stop 38. A solenoid valve 311 is provided on the inflation port of each inflatable compression pad 39. During installation, the air pipe of an external electric air pump is connected to the inflation port, and sufficient air is injected into the inflatable compression pad 39 to compress and limit the rear wheels of the vehicle to prevent the vehicle from rolling backward after being raised and causing an accident.

[0039] Combination Figures 1 to 5 As shown, it should be noted that the specific dimensions of each component in the application document are selected and installed according to the actual needs of the site. Before implementation, the wheel limiting mechanism 3 in this device is also set on the bottom surface of the multi-level parking garage 1 to limit the wheels of the lower parking spaces. For the specific installation process, refer to the installation process of the wheel limiting mechanism 3 installed at the bottom of the lifting parking platform 11. In addition, before implementation, the alarm flashing light and the pressure sensing switch 27 are connected and set in the garage. The connection principle is the same as that of the prior art, which will not be described in detail in the application document.

[0040] The working principle of this type of parking rack device for automated parking garages is as follows:

[0041] When a user chooses to park their vehicle in the upper parking space of the multi-level parking garage 1, a protective device 2 is installed on the lifting parking platform 11. When the vehicle touches it, the rubber protective roller 23 swings and touches the pressure sensor switch 27. At this time, the pressure sensor switch 27 activates the alarm flashing light to provide an alarm warning to the user until the vehicle is completely parked. The rubber protective roller 23 can protect the vehicle body and effectively prevent the vehicle from being scratched.

[0042] After the user's vehicle is parked, the two front wheels drive into the front wheel seats 31, pressing down on the pedals 32. This causes the levers 37 below each pedal 32 to press down on one end of the lever 34, lowering its height. At this time, the lower pressure column 310 at the bottom of the lever 34 compresses the return spring 36 inside the mounting cylinder 35, causing the return spring 36 to deform and generate a rebound force. Meanwhile, the other end of the lever 34 lifts up, extending the two rear wheel seats 38 along with the inflatable compression pads 39 from the extension slots 112 of the lifting parking platform 11. This controls the opening of the solenoid valve 311, allowing an external electric air pump to inject sufficient air into the inflatable compression pads 39, which is used to compress and limit the rear wheels of the vehicle, preventing the vehicle from rolling backward and causing an accident, thus improving safety. When retrieving the vehicle, the above operation is repeated. Under the action of the rebound force of the return springs 36, the rear wheel seats 38 along with the inflatable compression pads 39 are retracted into the extension slots 112.

[0043] After the user parks the car, the four lifting hydraulic cylinders 131 are activated simultaneously to provide power for driving, so that each sprocket 132 drives the lifting chain 133 to pull the lifting parking plate 11 to lift and lower.

[0044] When a user parks their vehicle in the lower level of the automated parking garage 1, four hydraulic cylinders 131 are simultaneously activated to provide power, causing each sprocket 132 to drive the lifting chain 133 to pull the lifting parking platform 11 up and down. At this time, the mounting blocks 251 and the telescopic guardrail 252 on both sides of the lifting parking platform 11 rotate. Since the telescopic guardrail 252 consists of several interlocking rubber cylinders 254, each cylinder is pulled out as the parking platform 11 is raised. When a vehicle touches the cylinder, the rubber cylinder 254 contacts the pressure sensor switch 27, triggering an alarm and providing a warning to the user until the vehicle is fully parked. The multiple rubber cylinders 254 also protect the vehicle body, effectively preventing scratches and providing double-layer parking space protection.

[0045] After a user's vehicle is parked, the wheel limiting mechanism 3 limits the tires of the vehicle in the lower parking space, as described above.

[0046] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
