Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional parking garages, and particularly to a double-layer three-dimensional side parking garage. Background Art

[0002] With the increase in the number of vehicles, the number of roadside parking spaces has not increased correspondingly. This has caused great difficulties for car owners when looking for parking spaces when going out. To solve this problem, double-layer three-dimensional side parking garages have been applied in the parking field. The use effects of double-layer three-dimensional parking garages are mainly reflected in aspects such as saving space, improving space utilization rate, being convenient and fast, having high safety performance, being easy to operate, having a high degree of intelligence, and having low maintenance costs. The design of the double-layer three-dimensional parking garage makes full use of the vertical space. Through mechanical operation, more vehicles can be parked in a limited space, thus effectively solving the problem of difficult urban parking. This parking method not only saves land resources, improves space utilization rate, but also greatly improves the efficiency of roadside parking and reduces the waiting time for car owners to find parking spaces.

[0003] Currently, since the three-dimensional garage stores vehicles in a mechanized manner, each parking space can access and store vehicles through lifting or lateral movement. Therefore, the length and width of each parking space are smaller than the standard roadside parking space size. Secondly, in order to facilitate the driver to get out of the vehicle after parking, the baffle on the parking space is relatively low. In order to facilitate the vehicle to enter the parking space, a ramp is provided between the parking space and the ground. As a result, some drivers with less parking experience may step on the accelerator or throttle too hard during parking, resulting in too fast a vehicle speed and being prone to rushing out of the parking space, causing the problem of vehicle falling. This is not conducive to safely parking the vehicle in the three-dimensional garage set by the roadside. Summary of the Invention

[0004] The present invention provides a double-layer three-dimensional side parking garage, which has the beneficial effect that hydraulic oil can quickly flow into the limit seat, prompting the limit seat to quickly move upward to limit the front wheels, avoiding the problem that when parking, due to excessive force, the vehicle slides off the parking board, and improving the safety performance of the vehicle use in the three-dimensional garage. It solves the problem that in the above-mentioned background art, some drivers with less experience step on the accelerator or throttle too hard during parking, resulting in too fast a vehicle speed and being prone to rushing out of the parking space, causing the problem of vehicle falling, which is not conducive to safely parking the vehicle in the three-dimensional garage set by the roadside.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the double-layer stereo side parking garage, the lifting height of the parking plate fixed on the mounting block can be adjusted conveniently through the screw rod assembly arranged on the hollow column, and the horizontal rotation angle of the hollow column can be adjusted conveniently through the motor assembly installed on the base, so that the working angle of the parking plate can be adjusted, so that the vehicle on the parking plate can be parked sideways at high altitude on the roadside, and the rear limit strip fixed on the parking plate can limit the rear wheel. If the rear wheel of the vehicle passes over the rear limit strip, the pressure plate can be contacted, so that the pressure plate is affected by the wheel pressure and moves downward to conflict with the linkage assembly, and one end of the linkage assembly can be tilted to conflict with the conflict assembly on the hydraulic oil tank, so that the conflict assembly can conflict with the movable plate in the hydraulic oil tank, and the hydraulic oil in the hydraulic oil tank can be squeezed upward, so that the hydraulic oil can quickly flow into the limit seat, so that the limit seat can quickly move up to limit the front wheel, so as to avoid excessive force when parking, so that the vehicle slips from the parking plate, thereby improving the safety performance of vehicles in the stereo garage.

[0018] 2. In the double-layer stereoscopic side parking garage, through the multiple oil inlet chambers arranged in the limit seat, the hydraulic oil in the hydraulic oil tank can enter the oil inlet chamber through the oil nozzle for filling when being squeezed, so as to realize the purpose of lifting multiple front limit blocks upward. Due to the different wheelbases of the vehicles, the distances between the front and rear wheels of the vehicles are different. When the front wheels of the vehicles move to the limit seats, some front limit blocks that are not in contact with the wheels are subjected to less pressure. By injecting hydraulic oil into the oil inlet chamber, the front limit blocks can be raised to the top, so as to limit the front wheels. At the same time, when the first interference block moves, the interference force with the L-shaped interference block can be reduced, so that the installation strip drives multiple positioning blocks to move, which can be automatically inserted into the positioning plug on the front limit block, so as to avoid the front limit block at the top position from falling, so as to facilitate the front limit block to jam the wheel and keep it motionless. The front limit block that is in contact with the wheel but not fully raised will form a small height difference with the front limit block that is fully raised, affecting the parking stability of the vehicle. At the same time, the front limit block that is not fully raised will be resisted by the wheel, which will increase the pressure inside the oil inlet chamber. The conical plug arranged in the oil return port of the oil inlet chamber can be pushed to move horizontally when the pressure inside the oil inlet chamber is relatively high, so that the hydraulic oil inside the oil inlet chamber can flow back into the hydraulic oil tank, thereby achieving the purpose of pressure relief, and facilitating the front limit block that is in contact with the wheel to be pressed back to the lowest point, so that a large height difference is formed between the unpressed front limit block and the pressed front limit block, thereby greatly increasing the resistance to vehicle movement and further improving the limiting effect. The temporary storage tank arranged at one end of the hydraulic oil tank can be used to divide the pressure when the internal pressure of the hydraulic oil tank is relatively high, thereby improving the pressure relief effect of the oil inlet chamber.

[0019] 3. In this double - layer three - dimensional side - parking garage, the pneumatic horn can be conveniently installed through the rectangular base. When the airbag set on the pneumatic horn is pressed, the pneumatic horn will emit a sound, which can give a warning reminder to the driver who controls the vehicle to cross the rear limit bar. Through the contact rod fixed on one side of the first contact block, it can move synchronously with the first contact block, so that the contact rod can intermittently contact with several arc - shaped contact blocks fixed on the pressing plate, achieving the purpose of the pressing plate reciprocally pressing the airbag, enabling the pneumatic horn to continuously emit warning sounds, and greatly improving the warning effect.

A contact assembly is arranged on the hydraulic oil tank 9. A linkage assembly is arranged between the contact assembly and the pressing plate 31. The movable plate 11 is urged to vertically move in the hydraulic oil tank 9 through the linkage assembly and the contact assembly.

[0033] The motor assembly includes a first servo motor 101 , which is fixed on the base 1 , and a bevel gear 102 is fixed on the motor shaft of the first servo motor 101 , and a bevel gear 103 is fixed on the rotating shaft 2 , and the bevel gear 102 and the bevel gear 103 are meshed with each other.

[0034] The screw assembly includes a screw 61, which is rotatably connected to the hollow column 3. A movable bracket 62 is threadedly connected to the screw 61.

A second servo motor 63 is fixed to the top of the hollow column 3, and the motor shaft of the second servo motor 63 is transmission-connected to the screw 61 through a coupling.

[0035] The resistance assembly includes a sliding resistance frame 91 , a first resistance block 92 is fixed to the end of the sliding resistance frame 91 , the sliding resistance frame 91 is elastically connected to the hydraulic oil tank 9 via a third spring 94 , a second resistance block 93 is fixed on the movable plate 11 , and the second resistance block 93 resists the sliding resistance frame 91 .

[0037] The parking garage is set up on the roadside. Under normal circumstances, vehicles can be parked in the parking spaces on both sides of the road. When the parking spaces on the road are used up, the vehicles can be parked in the parking garage. The parking garage can lift the vehicles and rotate them to achieve the purpose of stacking the vehicles. In this way, 2, 3 or even more vehicles can be parked at the same position on the side of the road. When the vehicle to be parked needs to be parked in the three-dimensional garage, the parking board 5 of the three-dimensional side garage is controlled to be lowered to the ground, and the vehicle is driven onto the parking board 5. Figures 1 - 3The rear limit strip 4 fixed on the parking plate 5 can limit the rear wheel. If the vehicle is used to cause the rear wheel to cross the rear limit strip 4, the vehicle can contact the pressure plate 31, causing the pressure plate 31 to move downward under the pressure of the vehicle, so that the first spring 8 fixed on the mounting block 7 accumulates force, and the downward sliding pressure plate 31 simultaneously conflicts with the two rockers 52 of the linkage assembly, causing the rocker 52 to rotate on the shaft 51, and at the same time, the torsion spring 53 accumulates force, and one end of the rotating rocker 52 conflicts with the first conflicting block 92 of the sliding conflicting frame 91 upward, causing the first conflicting block 92 to drive the sliding conflicting frame 91 to move horizontally on the hydraulic oil tank 9, and the third spring 94 accumulates force, which can achieve the purpose of the sliding conflicting frame 91 conflicting with the second conflicting block 93, causing the movable plate 11 to move vertically upward in the hydraulic oil tank 9. , the hydraulic oil is squeezed into the limit seat 12, so that the hydraulic oil can quickly flow into the limit seat 12, prompting the limit seat 12 to move up quickly to limit the front wheel, avoiding excessive force when parking, which may cause the vehicle to slip from the parking board 5, thereby improving the safety performance of vehicles in the three-dimensional parking garage. After the vehicle is parked, the second servo motor 63 in the screw rod assembly is started, and the second servo motor 63 drives the screw rod 61 to rotate in the hollow column 3, prompting the movable bracket 62 to drive the parking board 5 to move upward through the support frame 6, thereby raising the height of the vehicle, and starting the first servo motor 101 in the motor assembly. The first servo motor 101 drives the bevel gear 102 to rotate. When the bevel gear 102 is engaged with the bevel gear plate 103 fixed on the rotating shaft 2, it can drive the hollow column 3 to rotate, prompting the parking board 5 to rotate horizontally, thereby adjusting the parking angle of the vehicle.

[0038] Embodiment 2: This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figures 1 - 9 The limit seat 12 includes a plurality of oil inlet chambers 121 arranged along the length direction of the parking plate 5. The oil inlet chamber 121 is fixed on the hydraulic oil tank 9. The hydraulic oil tank 9 is provided with an oil nozzle 122. The oil nozzle 122 is connected to the oil inlet chamber 121. A front limit block 123 is slidably connected in the oil inlet chamber 121. A fourth spring 124 is connected between the front limit block 123 and the bottom of the oil inlet chamber 121.

[0039] The oil inlet chamber 121 is provided with an oil return port 13 , in which a conical plug 14 is provided. The conical plug 14 is elastically connected to the oil inlet chamber 121 via a fifth spring 141 , and the oil return port 13 is communicated with the hydraulic oil tank 9 .

[0040] One end of the hydraulic oil tank 9 is connected to a temporary oil tank 15 , a push plate 16 is slidably connected in the temporary oil tank 15 , and a sixth spring 17 is connected between the push plate 16 and the temporary oil tank 15 .

[0041] A mounting strip 18 is provided on the parking plate 5, and a plurality of positioning blocks 19 are slidably connected to the mounting strip 18, a ninth spring 32 is connected between the positioning block 19 and the mounting strip 18, a positioning plug 20 is fixed on the front limit block 123, the positioning plug 20 is adapted to the positioning block 19, a seventh spring 21 is connected between the mounting strip 18 and the parking plate 5, an L-shaped resistance block 22 is fixed at one end of the mounting strip 18, one end of the L-shaped resistance block 22 is in resistance to the first resistance block 92, and a resistance slope 23 is provided on one side of the first resistance block 92.

[0042] At present, the lengths of vehicles on the market are different, resulting in different wheelbases. During the parking process, the front wheel limit of the vehicle will be unstable, affecting the parking stability of the vehicle. Figures 2 - 8 , through the several oil inlet chambers 121 arranged in the limit seat 12, the hydraulic oil in the hydraulic oil tank 9 can enter the oil inlet chamber 121 through the oil nozzle 122 for filling when being squeezed, so as to realize the purpose of lifting the front limit block 123 upward, and at the same time the fourth spring 124 accumulates force. Due to the different wheelbases of the vehicles, the distances between the front and rear wheels of the vehicles are different. When the front wheels of the vehicles move onto the limit seat 12, some of the front limit blocks 123 that are not in contact with the front wheels are subjected to less pressure and can rise to the top end, so as to limit the front wheels. Some front limit blocks 123 are in contact with the front wheels and cannot be fully raised due to the pressure of the front wheels. At this time, the internal pressure of the oil inlet chamber 121 will be increased. At the same time, the height difference between the fully raised front limit block 123 and the incompletely raised front limit block 123 is small, which will affect the stability of the wheel limit. It is necessary to relieve the pressure in the oil inlet chamber 121, and through the oil return port 13 When the conical plug 14 is subjected to a relatively high pressure, the fifth spring 141 can be urged to store force, so that a gap is formed between the movement of the conical plug 14 and the oil drain port of the oil inlet chamber 121, so that the hydraulic oil inside the oil inlet chamber 121 can flow back to the hydraulic oil tank 9, thereby achieving the purpose of pressure relief, and facilitating the front limit block 123 in contact with the wheel to be pressed back to the lowest point, so that a larger height difference is formed between the unpressed front limit block 123 and the pressed front limit block 123, thereby greatly increasing the resistance to vehicle movement and further improving the limiting effect. At the same time, when the hydraulic oil inside the oil inlet chamber 121 flows back to the hydraulic oil tank 9, the oil pressure inside the hydraulic oil tank 9 will increase, affecting the reflux effect. The temporary storage tank 15 connected to one end of the hydraulic oil tank 9 can store part of the hydraulic oil, so that the hydraulic oil pushes the push plate 16 to move in the temporary storage tank 15, and at the same time the sixth spring 17 stores force.

[0043] refer to Figure 2 and Figure 4, one end of the installation bar 18 is fixed. In the initial state, the L-shaped abutting block 22 abuts against the first abutting block 92. As the first abutting block 92 moves, it causes the first abutting block 92 to contact the abutting inclined surface 23, and the ninth spring 32 releases elastic force, driving several positioning inserts 20 to move horizontally. Through the cooperation of the ninth spring 32, it is convenient to insert into the positioning inserts 20 when encountering them during the movement of the positioning inserts 20, and the purpose of limiting the front limiting block 123 can be achieved.

[0044] Embodiment 3, this embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1 - 9 , a rectangular seat 24 is fixed on one side of the hydraulic oil tank 9. An air horn 25 is fixed on the rectangular seat 24. An airbag 26 is arranged on the air horn 25. A pressing plate 27 is arranged on one side of the airbag 26. The pressing plate 27 is elastically connected to the rectangular seat 24 through an eighth spring 28. Several arc-shaped abutting blocks 29 are fixed on one side of the pressing plate 27. A abutting rod 30 is fixed on one side of the first abutting block 92, and the abutting rod 30 abuts against the arc-shaped abutting blocks 29.

[0045] In the prior art, when a vehicle is parked on a multi-story garage, due to the lack of a warning function, it is easy for the driver to exert too much force frequently during the parking process, which greatly affects the operation safety. Refer to Figures 4 - 5 , when the first abutting block 92 moves horizontally, it can drive the abutting rod 30 fixed on one side to move synchronously, so that the moving abutting rod 30 intermittently abuts against several arc-shaped abutting blocks 29 fixed on the pressing plate 27, prompting the pressing plate 27 to move repeatedly on the rectangular seat 24. At the same time, the eighth spring 28 continuously stores and releases elastic force, and the purpose of enabling the pressing plate 27 to reciprocally press the airbag 26 can be achieved, prompting the air horn 25 to continuously emit warning sounds, which can greatly improve the warning effect and can warn and remind the driver who controls the vehicle to cross the rear limiting strip 4.

[0046] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0047] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
