Description

Technical Field

[0001] This invention belongs to the field of transportation auxiliary equipment technology, and particularly relates to a highly adaptable ramp device and its application method. Background Technology

[0002] Displacement barriers refer to height differences caused by improper design of terrain, buildings, or transportation. They are very common in daily life. For example, such displacement barriers often exist between the edge of a boarding bridge and the edge of an airplane door, between the edge of a road surface and the edge of a bus door, and between the edge of a platform and the edge of a high-speed rail door, which seriously affect people's (especially those with leg disorders) normal passage.

[0003] As attached Figure 1 As shown, in the prior art, a ramp device is usually laid at the misaligned obstacle. By adjusting the angle of the ramp plate, the top and bottom ends of the ramp plate can be connected to the bottom surface and the high edge of the misaligned obstacle, respectively, to form a smooth transition ramp to assist in smooth passage.

[0004] However, traditional ramp devices can only adjust the tilt angle of the ramp. Since the length of the ramp remains constant, the larger the tilt angle, the further the top of the ramp is from the high edge of the misaligned obstacle, resulting in the ramp not being able to be properly connected or having a large gap after connection, which affects the user experience and poses a safety hazard. Therefore, it is necessary to design a highly adaptable ramp device and its application method to solve this problem. Summary of the Invention

[0009] Preferably, the extension plate is located at the bottom of the carrier plate, and the end of the carrier plate opposite to the inclined plate is provided with an inclined connecting surface. When the extension plate extends out of the carrier plate, the connecting surface contacts the carrier plate so that the carrier plate and the extension plate are transitionally connected.

[0011] Preferably, the base has an upward-opening receiving cavity inside, and the carrier plate is slidably connected to the receiving cavity in the vertical direction to open and close the opening of the receiving cavity and allow the extension plate and the second driving part to enter and exit the receiving cavity; the first driving part is installed in the receiving cavity.

[0012] Preferably, the bottom wall of the receiving cavity is provided with a vertical slide cylinder, the upper part is provided with a horizontal slide rail, and the carrier plate is provided with a slide column and a slider; the slide column is slidably connected to the slide cylinder so that the carrier plate and the receiving cavity are slidably connected in the vertical direction; the slider is slidably connected to the slide rail so that the extension plate and the carrier plate are slidably connected in the horizontal direction.

[0013] Preferably, the support assembly further includes a surrounding plate, which is mounted around the bottom periphery of the carrier plate and can move in and out of the receiving cavity with the carrier plate, and the surrounding plate has a first notch for the extension plate to extend and retract.

[0014] Preferably, the enclosure also has a second notch on the side opposite to the first notch, and the carrier plate and the inclined plate are hinged together by a hinge. One end of the hinge is fixed to the carrier plate, and the other end of the hinge passes through the second notch to the outside and is fixed to the inclined plate.

[0015] Preferably, the first drive unit includes a first lead screw motor, a guide rail, a guide seat, and a guide wheel. The guide rail is disposed in the receiving cavity. The guide seat is slidably mounted on the guide rail and has an inclined wheel groove. The first lead screw motor is fixedly mounted in the receiving cavity, and the output shaft of the first lead screw motor is fixedly connected to the guide seat. The guide wheel is mounted on the bottom of the carrier plate and slidably connected to the wheel groove.

[0016] Preferably, the guide wheel is rotatably mounted on the bottom of the carrier plate.

[0017] Preferably, both the top and bottom ends of the wheel groove are connected to horizontally arranged retention grooves.

[0018] Preferably, the guide rail has two parallel rails, the guide seat is synchronously slidably connected to the two guide rails, and the guide seat has two wheel grooves, and the guide wheel has two wheels that slide in cooperation with the two wheel grooves.

[0022] A method for using a highly adaptable ramp device includes the following steps: placing the base on the bottom surface of a misaligned obstacle, then activating the first drive unit to drive the carrier plate and the ramp plate to move upward synchronously, so that the end of the carrier plate away from the ramp plate aligns with the high edge of the misaligned obstacle; then swinging the ramp plate so that the end of the ramp plate away from the carrier plate contacts the bottom surface of the misaligned obstacle; the ramp plate and the carrier plate form a channel with a plane and a slope to pave the misaligned obstacle and assist passage.

[0023] Beneficial effects This invention provides a highly adaptable ramp device and its application method. The ramp device uses a base as a supporting foundation and a first driving unit that works in conjunction with a hinged carrier plate and ramp. This allows for easy control of their heights and adjustment of the ramp's tilt angle, quickly constructing a passage that adapts to different misaligned obstacles, demonstrating strong adaptability. Because the plane and ramp surfaces of the passage transition between each other and respectively contact the high edge and bottom surface of the misaligned obstacle, they can completely overcome the obstacle and avoid gaps, improving user experience and safety. Furthermore, the application method of this ramp device is perfectly applicable to various misaligned obstacles while retaining the corresponding functional effects. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0027] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component, or there may be an intervening component present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. Furthermore, the terms "center," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] See appendix Figure 2 -Appendix Figure 6 A highly adaptable ramp device includes a base 1, a support assembly 2, and a drive assembly 3. The support assembly 2 includes a carrier plate 21 and an inclined plate 22. The carrier plate 21 is horizontally arranged and slidably connected to the base 1 in the vertical direction. The inclined plate 22 is located beside the base 1, and one end of the inclined plate 22 is hinged to the carrier plate 21, while the other end can swing around the hinge point to adjust the angle. The drive assembly 3 includes a first drive part 31, which is installed in the base 1 and drivenly connected to the carrier plate 21 to drive the carrier plate 21 to move in the vertical direction.

[0029] Specifically, in use, the base 1 is placed on the bottom surface of the misaligned obstacle and the first drive unit 31 is activated to drive the carrier plate 21 and the inclined plate 22 to move upward synchronously until the end of the carrier plate 21 away from the inclined plate 22 aligns with the high edge of the misaligned obstacle. Then, the end of the inclined plate 22 away from the carrier plate 21 swings and contacts the bottom surface of the misaligned obstacle under the action of manual pressure or its own action, so that the inclined plate 22 and the carrier plate 21 form a channel with a plane and a slope to lay the misaligned obstacle and assist passage.

[0030] It should be noted that during use, the position of the base 1 remains unchanged, so the carrier plate 21 will not move in the horizontal direction, so that the carrier plate 21 can properly align with the high edge of different misaligned obstacles without creating gaps. Also, due to the restriction of the carrier plate 21, the end of the inclined plate 22 that is hinged to the carrier plate 21 will not move in the horizontal direction, so the carrier plate 21 and the inclined plate 22 will continue to align and avoid creating gaps.

[0031] In summary, this invention uses a base 1 as a supporting foundation and a first driving unit 31 designed to work in conjunction with a hinged carrier plate 21 and an inclined plate 22. This allows for easy control of their heights and adjustment of the tilt angle of the inclined plate 22, enabling the rapid construction of a passage that adapts to different misaligned obstacles and demonstrating strong adaptability. Furthermore, because the plane and slope of the passage transition between each other and respectively contact the high edge and bottom surface of the misaligned obstacle, the misaligned obstacle can be completely overcome, and gaps can be avoided. Therefore, this solution maintains contact with the high and low edges of the misaligned obstacle and prevents gaps during the adjustment of the tilt angle of the inclined plate 22, improving user experience and safety.

[0032] See appendix Figure 8 The bottom of the inclined plate 22 is provided with multiple reinforcing ribs 220. This design can increase the structural stability and load-bearing capacity of the inclined plate 22, effectively prevent the inclined plate 22 from twisting and deforming during use, and improve the service life of the inclined plate 22.

[0033] See appendix Figure 3 -Appendix Figure 6 When the bottom of the misaligned obstacle sidewall has protrusions forming multiple steps, the base is difficult to fit against the sidewall of the misaligned obstacle, which in turn causes the carrier plate 21, which moves in the vertical direction, to fail to smoothly align with the high edge of the misaligned obstacle, resulting in gaps and affecting normal use. To solve this problem, in this invention, the support component 2 also includes an extension plate 23, and the drive component 3 also includes a second drive part 32. The extension plate 23 is disposed on the opposite side of the inclined plate 22 and is slidably connected to the carrier plate 21 in the horizontal direction. The second drive part 32 is mounted on the carrier plate 21 and is drivenly connected to the extension plate 23 to drive the extension to extend and retract in the horizontal direction.

[0034] Specifically, in use, the base 1 is placed on the bottom surface of the misaligned obstacle, and the first drive unit 31 is activated to drive the carrier plate 21, the inclined plate 22, and the extension plate 23 to move upward synchronously until the extension plate 23 is level with the high edge of the misaligned obstacle. Then, the second drive unit 32 is activated to drive the extension plate 23 to move and extend horizontally to align with the high edge. The end of the inclined plate 22 away from the carrier plate 21 swings and contacts the bottom surface of the misaligned obstacle under artificial pressure or its own action, so that the inclined plate 22, the carrier plate 21, and the extension plate 23 together construct a channel with both flat and sloping surfaces to lay the misaligned obstacle and assist passage. Therefore, the design of the second drive unit 32 and the extension plate 23 allows this ramp device to adapt to misaligned obstacles of more terrains and effectively eliminates gaps, comprehensively improving adaptability, user experience, and safety.

[0035] See appendix Figure 3 -Appendix Figure 7 The extension plate 23 is located at the bottom of the carrier plate 21. The end of the carrier plate 21 facing away from the inclined plate 22 is provided with an inclined connecting surface 210, and the carrier plate 21 can be transitionally connected to the extension plate 23 through the connecting surface 210.

[0036] Specifically, when the second drive unit 32 drives the extension plate 23 to extend and protrude from the carrier plate 21 to align with the high edge of the misaligned obstacle, the connecting surface 210 contacts the carrier plate 21 to make the carrier plate 21 and the extension plate 23 transitionally connected. This design makes it easier for wheelchairs, trolleys and other equipment to pass between the carrier plate 21 and the extension plate 23, reduces the sense of obstruction, and further improves the user experience.

[0037] See appendix Figure 3 Appendix Figure 8 and attached Figure 10 The invention also includes a ranging unit 4, which is mounted on the extension plate 23 and electrically connected to the second drive unit 32 for precisely controlling the extension distance of the extension plate 23.

[0038] Specifically, when the carrier plate 21 moves upward so that the extension plate 23 is level with the high edge of the misaligned obstacle, the ranging unit 4 can measure the distance between the extension plate 23 and the side wall of the misaligned obstacle and transmit the data to the second drive unit 32. The second drive unit 32 can then precisely control the extension distance of the extension plate 23 so that the extension plate 23 is precisely aligned with the high edge of the misaligned obstacle. This eliminates gaps and prevents the extension plate 23 from impacting the obstacle, further improving adaptability, user experience, and safety.

[0039] It should be noted that the ranging unit 4 can be a component that can measure distance, such as an infrared sensor or an optical sensor. Since there are many types of related components, this invention does not limit them.

[0040] See appendix Figure 2 -Appendix Figure 10 The base 1 has an upward-opening receiving cavity 10 inside. The carrier plate 21 is slidably connected to the receiving cavity 10 in the vertical direction to open and close the opening of the receiving cavity 10 and allow the extension plate 23 and the second drive part 32 to enter and exit the receiving cavity 10. The first drive part 31 is installed inside the receiving cavity 10.

[0041] Specifically, during use, the first drive unit 31 is activated to move the carrier plate 21 upward and open the opening of the receiving cavity 10, so that the second drive unit 32 and the extension plate 23 are placed outside. At this time, the second drive unit 32 is activated to move the extension plate 23 horizontally and extend it to align with the high edge of the misaligned obstacle. After use, the second drive unit 32 is activated to move the extension plate 23 horizontally inward to below the carrier plate 21, and then the first drive unit 31 is activated to move the carrier plate 21 downward and close the opening of the receiving cavity 10, so that the second drive unit 32 and the extension plate 23 are hidden inside the receiving cavity 10.

[0042] Therefore, the design of the receiving cavity 10 provides space for components such as the first drive unit 31, the second drive unit 32, and the extension plate 23, making the ramp device more aesthetically pleasing when not in use. See appendix Figure 7 -Appendix Figure 10 The bottom wall of the receiving cavity 10 is provided with a vertical slide cylinder 10h, the extension plate 23 is provided with a horizontal slide rail 23h, and the carrier plate 21 is provided with a slide column 211 and a slider 212; the slide column 211 is slidably connected to the slide cylinder 10h so that the carrier plate 21 and the receiving cavity 10 are slidably connected in the vertical direction; the slider 212 is slidably connected to the slide rail 23h so that the extension plate 23 and the carrier plate 21 are slidably connected in the horizontal direction.

[0043] Specifically, the carrier plate 21 is driven by the first driving unit 31, which allows the slide column 211 to slide along the slide cylinder 10h; similarly, the extension plate 23 is driven by the second driving unit 32, which allows the slide rail 23h to slide on the carrier block 212.

[0044] It should be noted that in some embodiments, other sliding connection structures may be used between the carrier plate 21 and the receiving cavity 10, and between the extension plate 23 and the carrier plate 21. Since there are many types of related sliding connection structures and they are relatively common in the mechanical field, they will not be listed one by one in this invention, nor will they be limited.

[0045] See appendix Figure 7 -Appendix Figure 10 The support assembly 2 also includes a surrounding plate 24, which is mounted around the bottom periphery of the carrier plate 21 and can move in and out of the receiving cavity 10 with the carrier plate 21. A first notch 241 is provided on the surrounding plate 24 for the extension plate 23 to extend and retract.

[0046] Specifically, the enclosure 24 can surround the periphery of the carrier plate 21 when the carrier plate 21 opens the cavity 10, effectively shielding components such as the first drive part 31 and the second drive part 32 placed in the cavity 10. This not only improves the aesthetics but also reduces the possibility of debris entering the cavity 10 and damaging the relevant components. The design of the first notch 241 can provide an active channel for the extension plate 23, preventing the enclosure 24 from interfering with the normal movement of the extension plate 23.

[0047] See appendix Figure 7 -Appendix Figure 10 The enclosure 24 also has a second notch 242 on the opposite side of the first notch 241. The carrier plate 21 and the inclined plate 22 are hinged together by a hinge 5. One end of the hinge 5 is fixed to the carrier plate 21, and the other end of the hinge 5 passes through the second notch 242 to the outside and is fixed to the inclined plate 22.

[0048] Specifically, the design of the hinge 5 allows the inclined plate 22 to swing around one end of the carrier plate 21 to adjust the angle, while the design of the second notch 242 can reserve an installation position for the hinge 5, which can prevent the hinge 5 of the carrier plate 21 and the inclined plate 22 from interfering with the normal closing of the carrier plate 21 and the receiving cavity 10, making the overall structure more reasonable.

[0049] It should be noted that in some embodiments, other rotating connection structures can be used to replace the hinge 5. Since there are many types of related rotating connection structures and they are quite common in the mechanical field, they will not be listed one by one in this invention, nor will they be limited.

[0050] See appendix Figure 5 -Appendix Figure 10 The first drive unit 31 includes a first lead screw motor 311, a guide rail 312, a guide seat 313, and a guide wheel 314. The guide rail 312 is disposed in the receiving cavity 10. The guide seat 313 is slidably mounted on the guide rail 312 and is provided with an inclined wheel groove 3130. The first lead screw motor 311 is fixedly mounted in the receiving cavity 10, and the output shaft of the first lead screw motor 311 is fixedly connected to the guide seat 313. The guide wheel 314 is mounted on the bottom of the carrier plate 21 and is slidably connected to the wheel groove 3130.

[0051] Specifically, during use, the first lead screw motor 311 is started to drive the guide seat 313 to move forward along the guide rail 312, which in turn drives the guide wheel 314 to slide along the top of the wheel groove 3130, thereby causing the carrier plate 21 to move upward and open the opening of the receiving cavity 10. At this time, the second drive unit 32 is started to drive the extension plate 23 to move and extend in the horizontal direction to align with the high edge of the misaligned obstacle. After use, the second drive unit 32 is started to drive the extension plate 23 to move inward in the horizontal direction to below the carrier plate 21, and then the first lead screw motor 311 is started to drive the guide seat 313 to move in the opposite direction along the guide rail 312, which in turn drives the guide wheel 314 to slide along the bottom of the wheel groove 3130, thereby causing the carrier plate 21 to move downward and close the opening of the receiving cavity 10, so as to hide the second drive unit 32 and the extension plate 23 inside the receiving cavity 10. The first drive unit 31 adopts the above-mentioned structural design, which can effectively reduce the occupation of the height space of the accommodating cavity 10, making the overall structure more compact. At the same time, it can also buffer and offset some of the pressure on the carrier plate 21, and improve the load-bearing capacity of the carrier plate 21.

[0052] Furthermore, the guide wheel 314 is rotatably mounted on the bottom of the carrier plate 21. This design allows the guide wheel 314 to rotate during sliding, thereby reducing friction between the guide wheel 314 and the wheel groove 3130 and ensuring smoother sliding, thus improving structural stability and effectively reducing wear.

[0053] It should be noted that the first drive unit 31 may also directly adopt components with a travel stroke, such as an electric cylinder, or other structures with a travel stroke. Since there are many types of related components and structures, this invention does not impose any restrictions on them.

[0054] See appendix Figure 7 -Appendix Figure 9 The top and bottom of the wheel groove 3130 are connected to horizontally set retention grooves 3131.

[0055] Specifically, when the carrier plate 21 opens the cavity 10 and moves to its highest position, the guide wheel 314 enters the retention groove 3131 at the top of the groove 3130. This design allows the guide seat 313 to directly support the carrier plate 21 through the guide wheel 314, improving the load-bearing capacity of the carrier plate 21 and preventing the guide wheel 314 from sliding down the groove 3130 due to pressure on the carrier plate 21, thus preventing the guide seat 313 from retracting. This effectively prevents the guide seat 313 from putting pressure on the first lead screw motor 311 and reduces the possibility of damage to the first lead screw motor 311. When the carrier plate 21 closes the cavity 10, the guide wheel 314 is located in the retention groove 3131 at the bottom of the groove 3130. This design allows the guide wheel 314 to be evenly stressed on both the top and bottom sides, thus reducing the damage rate of the guide wheel 314.

[0056] See appendix Figure 7 -Appendix Figure 9 The guide rail 312 has two parallel rails, and the guide seat 313 is synchronously slidably connected to the two guide rails 312. The guide seat 313 has two wheel grooves 3130, and the guide wheel 314 has two wheels, which slide and cooperate with the two wheel grooves 3130 one by one.

[0057] Specifically, in use, the first lead screw motor 311 can drive the guide seat 313 to slide synchronously along the two guide rails 312, and cause the two wheel grooves 3130 to simultaneously press the two guide wheels 314, thereby driving the carrier plate 21 to move up and down. The cooperation between the guide seat 313 and the two guide rails 312, as well as the cooperation between the two guide wheels 314 and the two wheel grooves 3130, can effectively improve the structural stability and provide stronger support for the carrier plate 21, thereby improving the safety of use.

[0058] Furthermore, the first drive unit 31 is provided in two sets and symmetrically arranged in the receiving cavity 10, and the two sets of first drive units 31 are synchronously connected to the carrier plate 21 for driving. This design enables the two first drive units 31 to support and drive the carrier plate 21 synchronously, and ensures that the force on both sides of the carrier plate 21 is uniform and has a stronger load-bearing capacity, further improving the safety of use.

[0059] See appendix Figure 8 and attached Figure 10 The second drive unit 32 includes a second lead screw motor 321, which is mounted on the carrier plate 21 and the output shaft of the second lead screw motor 321 is fixed to the extension plate 23.

[0060] Specifically, when the carrier plate 21 moves upward, causing the second lead screw motor 321 and the extension plate 23 to move out of the receiving cavity 10, the second lead screw motor 321 is started to drive the extension plate 23 to move outward in the horizontal direction to connect with the high edge of the misaligned obstacle; after use, the second lead screw motor 321 is started to drive the extension plate 23 to move inward in the horizontal direction to below the carrier plate 21, and then the carrier plate 21 is controlled to move downward to hide the second lead screw motor 321 and the extension plate 23 in the receiving cavity 10.

[0061] It should be noted that when the ranging unit 4 is provided, the ranging unit 4 is electrically connected to the second lead screw motor 321 to control the stroke of the output shaft of the second lead screw motor 321; on the other hand, the second drive unit 32 may also adopt a component with a moving stroke, such as an electric cylinder, or other structures with a moving stroke. Since there are many types of related components and structures, this invention does not limit them.

[0062] Furthermore, the present invention also includes a storage battery (not shown in the figure) and a control board (not shown in the figure). Both the storage battery and the control board can be installed inside the base 1, and the control board can be electrically connected to the first lead screw motor 311, the second lead screw motor 321 and the ranging unit 4 to supply power to the first lead screw motor 311, the second lead screw motor 321 and the ranging unit 4, and control the running time and movement stroke of the first lead screw motor 311 and the second lead screw motor 321. Since the relevant control technology is relatively conventional, its specific circuit structure will not be described in detail in the present invention.

[0063] A method for using a highly adaptable ramp device includes the following steps: placing the base 1 on the bottom surface of the misaligned obstacle, then activating the first drive unit 31 to drive the carrier plate 21 and the ramp 22 to move upward synchronously, so that the end of the carrier plate 21 away from the ramp 22 aligns with the high edge of the misaligned obstacle; then swinging the ramp 22 so that the end of the ramp 22 away from the carrier plate 21 contacts the bottom surface of the misaligned obstacle; the ramp 22 and the carrier plate 21 form a channel with both a plane and a slope to lay the misaligned obstacle and assist passage; this method can be perfectly applied to many scenarios with misaligned obstacles and retains the corresponding functional effects, which will not be repeated here.

[0064] Among them, misaligned obstacles can exist between the edge of the boarding bridge deck and the edge of the aircraft door, between the road surface and the edge of the bus door, between the platform surface and the edge of the high-speed rail door, or even between the ground and the threshold of a residence. Due to the variety of related scenarios, this invention does not impose any limitations. However, for ease of understanding, an example of its use in the aircraft boarding bridge scenario is given below: Before boarding, staff will align the jet bridge with the parked aircraft door. Once the jet bridge contacts the aircraft and surrounds the door, the jet bridge surface is usually lower than the door threshold. At this point, using the method described above, the base 1 of the ramp device is first placed on the jet bridge surface and close to the outer wall of the aircraft. Then, the first drive unit 31 is activated to drive the carrier plate 21 and the ramp 22 to move upward synchronously, so that the end of the carrier plate 21 away from the ramp 22 aligns with the door threshold. Then, the ramp 22 is swung so that the end of the ramp 22 away from the carrier plate 21 contacts the jet bridge surface. The ramp 22 and the carrier plate 21 form a channel with both a flat surface and a slope to lay the jet bridge and the aircraft door, thus creating a passage for passengers to smoothly enter and exit the aircraft.

[0065] It should be noted that if there is a large gap between the boarding bridge and the aircraft after the boarding bridge is parked, the ramp device may also include a second drive unit 32 and an extension plate 23. In this case, the base 1 of the ramp device can be placed on the boarding bridge surface first, and then the first drive unit 31 can be activated to drive the carrier plate 21, the ramp plate 22 and the extension plate 23 to move upward synchronously, so that the extension plate 23 aligns with the threshold of the aircraft door. Then, the second drive unit 32 can be activated to drive the extension plate 23 to extend and connect with the threshold, and the end of the ramp plate 22 away from the carrier plate 21 can be swung to contact the boarding bridge surface.

[0066] It should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
