[0001] The present invention relates to a variable ramp device, in particular to a variable ramp device for cars to enter and exit a small underground or semi-underground three-dimensional garage. In one state, the variable ramp device forms a horizontal surface or is flush with the surrounding ground. In another state, the variable ramp device forms a ramp for cars to enter and exit the underground or semi-underground small three-dimensional garage. Background Art

[0002] As urban space becomes increasingly scarce, underground garages and multi-story parking garages are becoming more and more common.

[0003] In the prior art, the three-dimensional parking garage usually lifts the car as a whole, and the parking platform used when moving the car is usually set horizontally. The installation space of the lifting device needs to occupy a large space, and it is laborious to lift the car as a whole. It also affects the appearance and is unsafe.

[0009] The vertical lifting device includes an electric-controlled lifting device, and four vertical lifting supports are respectively provided with motors for driving the panel to vertically lift along the inclined support column and the fulcrum support column.

[0010] The vertical lifting device includes a pneumatic lifting device or a hydraulic lifting device, and the pneumatic lifting device or the hydraulic lifting device drives the fulcrum slider or the tilting slider to move up and down.

[0011] The vertical lifting device controls the vertical lifting distance range of the panel to be greater than or equal to half the height of the inclined support column; the length of the telescopic column is adjustable so that the angle between the panel and the horizontal direction is less than or equal to 8.6 degrees.

[0012] The rotation control device controls the panel to rotate with the connection between the panel and the fulcrum support column as the fulcrum so that the angle range is less than or equal to 8.6 degrees.

[0030] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 3In the embodiment of a variable ramp device shown, the support device includes a vertical support column 210 and a telescopic support column; one end of the vertical support column 210 is connected to the panel 270 through a rotating fulcrum, and one end of the telescopic support column is connected to the panel 270 through a rotating fulcrum; the other end of the vertical support column 210 is rotatably connected to the other end of the telescopic support column; the telescopic support column includes a fixed column 221 and a telescopic column 222; the telescopic column 222 is sleeved in the fixed column 221, and the telescopic column 222 can be extended or retracted relative to the fixed column 221; in the first state, the telescopic column 222 is in an extended or retracted state, and the panel 270 is in a horizontal state; in the second state, the telescopic column 222 is in a retracted or extended state, and the panel 270 is in a downward tilted or upward tilted state, forming a downward or upward ramp.

[0032] like Figures 1 to 3 In the embodiment of a variable ramp device shown, the length of the telescopic column is adjustable so that the angle between the panel and the horizontal direction is less than or equal to 8.6 degrees.

[0033] The height of a general garage is 2.2 meters, and the car's driving ramp is required to be below 8.6 degrees, which results in a relatively long panel length. A non-standard garage, based on 1.8 meters, also requires a length of 12 meters, which is not suitable for implementation in narrow spaces.

[0034] like Figures 4 to 5 In the embodiment of a variable ramp device shown, the support device includes two inclined support columns 110 and an inclined slider 113. The inclined support columns include a vertical slide 111 in the middle, and the inclined slider 113 can slide in the vertical slide 111 in the middle of the inclined support column 110. The panel 150 is rotatably connected to the inclined slider 113. The support device also includes two fulcrum support columns 120 and a fulcrum slider 123. The fulcrum support column 120 includes a vertical slide 121 in the middle, and the fulcrum slider 123 can slide in the vertical slide 121 in the middle of the fulcrum support column 120. The panel 150 is rotatably connected to the fulcrum slider 123. The inclined support columns 110 and the fulcrum support columns 120 have the same height, which is adapted to the vertical distance between the upper plane and the lower plane of the three-dimensional parking garage.

[0035] Figures 4 to 5 In an embodiment of a variable ramp device shown, the support control device also includes a vertical lifting device and a rotation control device, which are not shown in the accompanying drawings; the panel 150 includes two horizontal slide rails 160 arranged on both sides of the bottom of the panel, and the inclined slider 113 can slide in the horizontal slide rails 160; two inclined support columns 110 are symmetrically arranged on both sides of the panel 150; and two fulcrum support columns 120 are symmetrically arranged on both sides of the panel 150.

[0036] Figures 4 to 5In the embodiment of a variable ramp device shown, the variable ramp device in the transition state from the first state to the second state includes: the first step: the vertical lifting device first controls the fulcrum slider 123 and the inclined slider 113 to move synchronously, driving the panel 150 to vertically lift a certain distance in a horizontal state, at which time the panel 150 is still in a horizontal state; the second step: the rotation control device controls the inclined slider 113 to slide up or down, and the inclined slider 113 slides in the horizontal slide rail 160 at the same time, driving the panel 150 to rotate with the fulcrum slider 123 as the fulcrum, so that the panel 150 is in an inclined state, forming an upward or downward ramp for the car. The rotation control device control panel 150 rotates with the connection between the panel and the fulcrum support column as the fulcrum, and the angle range is less than or equal to 8.6 degrees. At this time, the connection between the panel 150 and the fulcrum support column 120 is the position where the fulcrum slider 123 stays.

[0037] The panel 150 in the variable ramp device first moves vertically, and the vertical movement distance can be as large as possible, so that the slope of the ramp formed by the panel 150 after rotation will be as gentle as possible, and the length of the panel 150 can meet the slope requirements, that is, it can meet the relationship between the length of the hypotenuse and the length of the two vertical sides in the Pythagorean theorem. This design method ensures that the vertical lifting height is high enough, and at the same time ensures that the angle of the panel tilt is relatively gentle, which is convenient for the car to enter and exit, so as to avoid a large slope that affects safe parking.

[0038] Figures 4 to 5 In the embodiment of the variable ramp device shown, the vertical lifting distance range of the vertical lifting device control panel 150 is greater than or equal to one half of the height of the inclined support column 110.

[0039] In some embodiments of the variable ramp device not shown in the accompanying drawings, the vertical lifting device includes an electric-controlled lifting device, and four vertical lifting supports are respectively provided with motors for driving the panel to vertically lift and lower along the inclined support columns and the fulcrum support columns.

[0040] In some embodiments of the variable ramp device not shown in the drawings, the vertical lifting device includes a pneumatic lifting device or a hydraulic lifting device, and the pneumatic lifting device or the hydraulic lifting device drives the fulcrum slider or the tilt slider to move up and down.

[0041] The moving power of the tilting slider or the fulcrum slider in the slideway can be any technology in the existing technology, such as chain drive, screw drive, cylinder drive, or electromagnetic drive. Of course, the up and down movement of the panel can also be achieved using existing mechanical technology.

[0042] like Figure 1 In the embodiment of a variable ramp device shown, the panel 270 is hollow in the middle. When the panel is horizontal, the hollow portion 272 is a vehicle chassis inspection channel; the hollow portion 272 is enclosed in the main body of the panel 270.

[0043] like Figure 4 In the embodiment of a variable ramp device shown, a hollow space is provided in the middle of the panel 150, and the hollow portion 152 is enclosed in the panel 150; the hollow portion 152 is used as a vehicle chassis inspection channel. This design further expands the applicable scenarios of the variable ramp device, making the variable ramp device also suitable for small car repair shops, or for observing and repairing the vehicle chassis when the variable ramp device is in a certain state, such as a horizontal state.

[0044] like Figures 6 to 7 As shown in the schematic diagram of the preferred embodiment of the variable ramp device and the three-dimensional parking garage, when the variable ramp device is in the first state, that is, Figure 6 When the variable ramp device 100 is in the second state, that is, the panel 150 is in a horizontal state, and the plane of the panel 150 is flush with the upper plane 500. Figure 7 state, at this time, the panel 150 is in an inclined state to form a ramp, and one end of the panel 150 obliquely crosses the lower plane 600, allowing the car to drive into the lower plane 600.

[0045] Figure 6 and 7 In the invention, an application scenario of a variable ramp device for entering an underground parking lot is given. By the same token, the variable ramp device can also have a reverse application scenario, such as being used as a ramp for entering a second-floor parking lot.

[0046] Traditional vertical car lifting devices require a larger space to install the drive motor or pneumatic device, and the drive motor or pneumatic device needs to be installed under the parking surface, which means that equipment installation space needs to be dug under the floor. For ordinary underground garages, this means designing a second underground floor, and traditional basements cannot be directly installed and used.

[0047] The technical solution of the present invention uses a mechanical device to enable the panel to change vertically as a whole, and to rotate around a fulcrum, which greatly reduces the length of the panel's individual rotation, while reducing the installation volume and mechanical complexity of the equipment required for individual vertical lifting and lowering, and reducing the requirements for the installation environment. When the width of the lifting room is 5 meters and the inclination is 8.6 degrees, that is, the slope is 15, at the bottom of the panel, close to the side of the fulcrum support column 120, the fulcrum support column still leaves a maximum of 0.75 meters of space, which can be used to install an electric motor or a pneumatic device.

[0048] In the above scenario, by cleverly setting the supporting device, it is more convenient for the car to transfer position in the small stereo garage. In the home application scenario, such as in a city villa or a rural courtyard, there are many such small stereo garages, and the device of the present invention is very suitable for such occasions.

[0049] When the panel of the variable ramp device is in a horizontal state, the panel surface can be used as horizontal parking or maintenance or horizontal passage or as an anti-theft door for closing the garage; when the panel is in a tilted state, a ramp is formed for cars to enter and exit the small three-dimensional garage; the variable ramp device, through a mechanical device, enables the panel to move vertically up and down as a whole, and to rotate around the fulcrum, which greatly reduces the ramp length required when the panel rotates alone, while reducing the installation volume and mechanical complexity of the machinery and equipment required for the independent vertical lifting and lowering changes, and reducing the requirements for the installation environment.

[0050] Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 In the figure, a three-dimensional schematic diagram of the variable ramp device with a canopy and a double-layer stereoscopic carport and left-view perspective views of several usage states are given;

[0051] As shown in the figure, garage 510 and garage 520 are arranged as upper and lower garages. In scenes such as villas, the garage can be designed as a semi-basement, and the height of the ground is about 1.1 meters away from the ground of garage 520. That is, when panel 270 is lowered to the ground and the rotation angle remains unchanged, the height difference is shortened, and the length of panel 270 can be controlled between 5 and 7 meters. In this scenario, the structural strength of panel 270 can be guaranteed.

[0052] Figure 8 In the embodiment, a canopy can be placed on the variable ramp device. In this scenario, when the panel 270 is laid flat, one car can be placed on the panel, and three cars can be placed in a limited space.

[0053] Fig.10 When the panel 270 is laid flat, a vehicle can be placed on the panel, or the panel can be used as a maintenance platform.

[0054] Fig.11 In the middle, when the panel 270 is lifted up, the car can enter the upper garage 510;

[0055] Fig.12 When the panel 27 is lowered, the car can enter the lower garage 520.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
