Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of double-layer parking lot, and in particular relates to a double-layer parking space that can be raised and lowered smoothly. Background Technology
[0002] With the improvement of economic level and the continuous increase in car ownership, the contradiction between supply and demand of parking spaces in cities is becoming increasingly prominent. Especially in places such as old residential areas, commercial complexes, and hospitals, the contradiction between supply and demand of parking spaces is particularly prominent. Double-layer parking spaces can effectively solve these problems, not only improving land utilization but also conforming to the concept of green and low-carbon development. However, in actual use, existing vertical double-layer parking spaces generally have the problem that vehicles parked in the upper layer are not in a centered position, causing the overall center of gravity of the upper layer parking space to shift. As a result, during descent, there is a high frequency of different pressures on the left and right sides and different descent speeds. If the shift is too large, it may cause vehicles to scrape or even fall. Therefore, it is necessary to design a double-layer parking space with smooth lifting. Utility Model Content
[0003] The purpose of this invention is to provide a smoothly lifting double-layer parking space to solve the problems mentioned in the background art.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] A smoothly lifting double-layer parking space includes a lower parking space, a lifting mechanism, and an upper parking space connected in sequence. The lower parking space includes a base plate with a mechanical safety lock. The lifting mechanism includes symmetrically arranged scissor arms, lifting cylinders, and locking arms. The lower end of the locking arm is equipped with rollers. A power supply box and a balance cylinder are located on one side of the lower parking space. A pump station is located on one side of the balance cylinder. The balance cylinder has two oil outlet pipes and two oil inlet pipes. The two oil outlet pipes are connected to the two lifting cylinders respectively, and the two oil inlet pipes are connected to the pump station. The pump station is equipped with a throttle valve and an overflow valve. The power supply box contains several removable batteries.
[0006] Furthermore, an explosion-proof valve for the hydraulic cylinder is provided on one side of the lifting cylinder.
[0007] Furthermore, the power supply box contains two batteries.
[0008] Furthermore, the battery is a rechargeable battery.
[0009] Furthermore, a T-junction is provided between the two oil inlet pipelines and the pump station.
[0010] Furthermore, the upper parking space is equipped with tire grooves.
[0011] Furthermore, the pump station is located inside the electrical control cabinet.
[0012] Furthermore, the pump station is equipped with an electromagnetic unloading valve.
[0013] Furthermore, the mechanical safety lock is fixed to one side of the lower end of the locking arm.
[0014] This utility model has the following beneficial effects:
[0015] This invention can improve the space utilization of parking spaces, allowing two vehicles to be parked simultaneously. The upper parking space can lift vehicles weighing up to 2700 kg. The lifting height of the upper parking space can be automatically adjusted according to the height of the parked vehicle to meet the height requirements of most vehicles. It has good performance and adaptability, and operates with low noise, reaching below 80 dB. It is equipped with a removable battery, which can be used in places without power, greatly increasing the scope of use of the equipment.

The combination of multiple operation methods makes it simple to operate and avoids the problem of the vehicle's normal use being affected when the remote control is lost. It has good adaptability and good performance.
[0017] This invention features a mechanical safety lock. When the upper parking space is raised to its position, the mechanical safety lock automatically locks, and the weight of the vehicle in the upper parking space is reliably pressed against the safety lock without any additional hydraulic energy, thus reducing operating costs. When the power supply is turned off or interrupted, or when the hydraulic system leaks, the safety lock remains locked until it can be unlocked manually or remotely. It is simple to operate, has a high overall safety factor, good performance, and high work efficiency.
[0018] By setting up a balance cylinder, even when the upper-level vehicle is parked off-center and its center of gravity is not centered, the hydraulic system can still automatically adjust to achieve a smooth and uniform descent on both sides, improving the overall safety and user experience, and making it highly adaptable.
[0019] By setting a throttle valve, users can adjust the descent speed of the parking space according to their own experience or personal habits. For example, if the noise is too loud when the descent speed is too fast, it can be achieved by reducing the descent speed. It is simple to operate, highly adaptable, and has high work efficiency.
[0020] By setting an overflow valve, the system pressure can be adjusted, and the lifting capacity of the parking space can be changed. It has good adaptability and good performance.
[0021] By incorporating removable batteries and converting the existing 220V / 380V power supply to 24V, parking spaces can be used even in areas without power. Powered by batteries, when the battery is low or insufficient, it can be directly replaced with a fully charged new battery, making it highly adaptable and effective. Depleted batteries can be fully charged and reused. Attached Figure Description

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0027] Please see Figure 1-3 As shown, this utility model is a double-layer parking space that can be smoothly raised and lowered. Figure 1 As shown, the smoothly lifting double-layer parking space in this embodiment includes a lower parking space 1, a lifting mechanism, and an upper parking space 2 connected in sequence. The lower parking space 1 includes a base plate 11, on which a mechanical safety lock 9 is provided. The lifting mechanism includes symmetrically arranged scissor arms 7, lifting cylinders 6, and locking arms 8. The lower end of the locking arms 8 is provided with rollers 12. A power supply box 4 and a balance cylinder 3 are provided on one side of the lower parking space 1. A pump station is provided on one side of the balance cylinder 3. The balance cylinder 3 is provided with two oil outlet pipes and two oil inlet pipes. The two oil outlet pipes are respectively connected to the two lifting cylinders 6, and the two oil inlet pipes are connected to the pump station. The pump station is provided with a throttle valve 52 and an overflow valve 53. The power supply box 4 is provided with several removable batteries.
[0028] The lifting cylinder 6 is equipped with an explosion-proof valve on one side.
[0029] The power supply box 4 contains two batteries.
[0030] The battery is a rechargeable battery.
[0031] A tee is provided between the two oil inlet pipelines and the pump station.
[0032] The upper parking space 2 is equipped with tire grooves 22 and damping strips 21.
[0033] The pump station is located inside the electrical control cabinet 5.
[0034] The pump station is equipped with an electromagnetic unloading valve 51.
[0035] The mechanical safety lock 9 is fixed to one side of the lower end of the locking arm 8.
[0036] During operation, the double-layer parking space starts at its lowest position. The vehicle is parked in the upper parking space 2 using a reverse parking maneuver. After parking, the rear wheel rims of the vehicle fall into the tire grooves 22. After the driver gets out of the vehicle, they can use the remote control to press the lift button to raise the lifting mechanism.
[0037] By pressing the up button on the remote control or by manually operating it through the electrical control cabinet 5, the mechanical safety lock 9 is unlocked. During the lifting process of the parking space, the motor 55 drives the gear pump 54 to pump hydraulic oil into the balance cylinder 3. The balance cylinder 3 distributes the hydraulic oil evenly to the lifting cylinder 6 through two oil outlets. The lifting cylinder 6 drives the elevator to gradually rise. The roller 12 slides to the right and passes over the stop block 91 in turn until it rises to the appropriate height. The mechanical safety lock 9 is locked on the stop block 91.
[0038] By pressing the lift button on the remote control or by manually operating the control cabinet 5, the mechanical safety lock 9 is unlocked, and the hydraulic oil stored in the balance cylinder 3 is pushed back to the pump station. Although the vehicle's center of gravity is not centered, the balance cylinder 3 will always maintain the balance of oil in the two lifting cylinders 6, so that it can descend smoothly until it falls back to the lowest position.
[0039] See Figure 3 Each side of the parking space has a locking arm 8 with two rollers 12. A connecting shaft is provided between the two rollers 12. A connecting cylinder is fixedly connected to the locking arm 8 on the outside of the connecting shaft. A mechanical safety lock 9 is fixedly connected to one side of the connecting cylinder. The mechanical safety lock 9 includes a safety block in the shape of the number 7. The recessed part of the safety block can be locked with the stop block 91. When the two are locked, the safety lock is in the locked state. The safety block has a through groove running vertically through the middle. Inside, there is an adjusting plate that is rotatably connected. The adjusting plate is a right trapezoid. When the parking space rises, the locking arm 8 drives the mechanical safety lock 9 to move to the right. After the adjusting plate encounters the stop block 91, it rotates to the left along the upper axis and slides past the stop block 91 until the lifting mechanism rises to the appropriate position. Then the adjusting plate contacts and locks the stop block 91, that is, the mechanical safety lock 9 is in the locked state. When the parking space descends, the locking arm 8 drives the mechanical safety lock 9 to slide to the right to unlock and then move to the left. After the adjusting plate encounters the stop block 91, it stands up and drives the safety block past the stop block 91 until the lifting mechanism descends to the lowest position.
[0040] This invention can improve the space utilization of parking spaces, allowing two vehicles to be parked simultaneously. The upper parking space 2 can lift vehicles weighing up to 2700 kg. The lifting height of the upper parking space 2 can be automatically adjusted according to the height of the parked vehicle to meet the height requirements of most vehicles. It has good performance and adaptability, and the operating noise is low, reaching below 80 dB. It is equipped with a removable battery, which can be used in places without power, greatly increasing the scope of use of the equipment. It can achieve smooth lifting and lowering, and has a good user experience.
[0041] This invention can be remotely operated via a remote control or manually operated via a pump station. The combination of multiple operation methods makes it simple to operate and avoids the problem of the vehicle's normal use being affected when the remote control is lost. It has good adaptability and good performance.
[0042] This invention features a mechanical safety lock 9. When the upper parking space 2 is raised to its position, the mechanical safety lock 9 automatically locks, and the weight of the vehicle in the upper parking space 2 is reliably pressed on the safety lock without any additional hydraulic energy, thus reducing operating costs. When the power supply is turned off or interrupted, or when the hydraulic system leaks, the safety lock remains locked until it can be unlocked manually or remotely. The operation is simple, the overall safety factor is high, the use effect is good, and the work efficiency is high.
[0043] By setting up balance cylinder 3, even when the upper vehicle is parked off-center and its center of gravity is not centered, the hydraulic system can still automatically adjust to achieve a smooth and uniform descent on both sides, improving the overall safety factor and user experience, and making it highly adaptable.
[0044] By setting the throttle valve 52, users can adjust the descent speed of the parking space according to their own experience or personal habits. For example, if the noise is too loud when the descent speed is too fast, the descent speed can be reduced to achieve the desired effect. The operation is simple, highly adaptable, and has high work efficiency.
[0045] By setting the overflow valve 53, the system pressure can be adjusted, the lifting capacity of the parking space can be changed, and the adaptability and performance are good.
[0046] By incorporating removable batteries and converting the existing 220V / 380V power supply to 24V, parking spaces can be used even in areas without power. Powered by batteries, when the battery is low or insufficient, it can be directly replaced with a fully charged new battery, making it highly adaptable and effective. Depleted batteries can be fully charged and reused.
