Description

Technical Field

[0001] This utility model relates to the field of barrier-free ramp technology, and in particular to a buffer device for urban barrier-free ramps. Background Technology

[0002] Urban barrier-free ramp buffer devices refer to functional facilities installed on barrier-free ramps in urban public buildings and road spaces. Through physical structure or material properties, they generate resistance or buffering effect on passing wheelchairs, pedestrians and vehicles to slow down their movement, reduce impact, and ensure passage safety and comfort.

[0003] A search revealed Chinese Patent Publication No. CN217461240U, which discloses an urban barrier-free ramp buffer device, relating to the technical field of urban planning. This urban barrier-free ramp buffer device includes a ramp body, a hollowed-out groove, a slot, and a spring. A support base is provided on the top of the spring, and a semi-circular groove is formed on the top of the support base. A bearing is installed inside the semi-circular groove, and a support tube is inserted into the center of the bearing. The support tubes are symmetrically arranged, and a pedal is provided on the side of the support tube closest to the center of the ramp body. A rope is threaded through the inside of the pedal, and both ends of the rope are fixedly connected to the inner wall of the ramp body. The design incorporates several pedals that can be lowered by springs, creating a wave-like oscillation on their surfaces, thus increasing cushioning. The reduced rotational connection between the support tubes and bearings at both ends of the pedals allows for more flexible rotation, enhancing pedal flexibility. Internal ropes further improve the oscillation direction and stability of the pedals, further enhancing the cushioning effect. However, the overall cushioning effect of this urban accessible ramp buffer device is poor, failing to effectively protect pedestrians. This makes pedestrians prone to falls and injuries while walking on ramps, failing to meet user needs, inconvenient to use, and reducing the efficiency and effectiveness of the buffer device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an urban barrier-free ramp buffer device, which aims to improve the problem that the existing urban barrier-free ramp buffer devices have poor buffering effect, cannot effectively protect pedestrians, and cause pedestrians to easily fall and get injured when walking on the ramp. They cannot meet people's needs, are inconvenient to use, and reduce the efficiency and effectiveness of the buffer device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a buffer device for an urban barrier-free ramp, comprising a ramp body, wherein multiple columns are fixedly connected at equal intervals on both the left and right sides of the top wall of the ramp body, and a buffer mechanism is provided inside the columns to reduce the impact force when a pedestrian falls; a protective mechanism is provided inside the ramp body to provide additional protection; the buffer mechanism includes a square groove, which is opened on the top wall of the ramp body, a support frame is provided on the bottom wall of the square groove, a buffer pad is installed on the top wall of the support frame, and a fixing component is provided on the top of the ramp body.

[0006] Through the above technical solution: the buffer mechanism is used to reduce the impact force when pedestrians fall, the protective mechanism is used to provide additional protection, when pedestrians walk on the ramp, the buffer pad absorbs the impact force through its high elasticity, reducing the impact force when pedestrians fall, and the support frame ensures the stability and durability of the buffer pad.

[0007] As a further description of the above technical solution: The fixing component includes a bolt one, which has threads at the four corners of the inner bottom wall of the square groove one. A bolt two is threaded to the inner wall of the bolt one, and a spring is installed at the bottom of the bolt two. Square grooves two are provided on the front and rear sides of the lower middle part of the outer wall of the bolt one. A locking block is rotatably connected to the inner wall of the square groove two. Square grooves three are provided around the lower middle part of the outer wall of the bolt two.

[0008] The above technical solution involves rotating the top bolt 2 of bolt 1 downwards, compressing the bottom spring, and causing the locking block to rotate within the square groove 2, thus flipping the locking block outwards and further fixing bolt 1 within the square groove 1.

[0009] As a further description of the above technical solution: The protective mechanism includes two bidirectional threaded rods, both of which are located on the left and right sides inside the slope. Threaded blocks are threaded to the front and rear sides of the outer walls of the bidirectional threaded rods. A connecting block one is fixedly connected to the top wall of each threaded block. A connecting block two is rotatably connected to the inner side of the outer wall of the connecting block one. A connecting block three is rotatably connected to the top of the connecting block two. Fixing plates are fixedly connected to the top walls of both connecting blocks three. Handrails are installed on the top walls of the fixing plates. A drive assembly is installed inside the slope.

[0010] Through the above technical solution: the bidirectional threaded rod drives the threaded blocks to move in opposite directions simultaneously, the threaded blocks drive the first connecting block to move, and the first connecting block drives the third connecting block to move through the second connecting block, thus achieving flexible adjustment of the handrail height.

[0011] As a further description of the above technical solution: The drive assembly includes a dual-head motor, which is fixedly connected to the lower part of the inner wall of the slope. The output end of the dual-head motor is fixedly connected to a connecting shaft, and the end of the connecting shaft is fixedly connected to a bevel gear one. The outer front side of the outer wall of the bevel gear one is meshed with a bevel gear two, which is fixedly connected to the rear end of the outer wall of the bidirectional threaded rod.

[0012] Through the above technical solution: the dual-head motor drives the connecting shaft to rotate, the connecting shaft drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear on the front side, and the second bevel gear drives the bidirectional threaded rod to rotate.

[0013] As a further description of the above technical solution: The support frame is threadedly connected to the square groove by bolt one, and the locking block is set inside the square groove two.

[0014] Through the above technical solution: Bolt 1 is used to initially fix the support frame in square groove 1, and square groove 3 on bolt 2 allows the locking block to rotate in square groove 2.

[0015] As a further description of the above technical solution: Each of the columns has a sliding groove on an adjacent side of its outer wall, and the sliding groove is slidably connected to the fixing plate.

[0016] The above technical solution ensures that the fixed plate can only slide up and down along the groove direction, thus guaranteeing the stability of the handrail when it is raised, lowered, or unfolded.

[0017] As a further description of the above technical solution: The inner bottom wall of the slope is fixedly connected to slide rails on both the left and right sides, and sliders are slidably connected to the inner walls of the slide rails on both the front and rear sides. The bottom wall of the threaded block is fixedly connected to the top wall of the slider.

[0018] The above technical solution ensures that the sliding connection between the slider and the slide rail ensures that the threaded block moves horizontally only along the slide rail direction when the bidirectional threaded rod rotates. The slider is used to support the weight of the threaded block and reduce the load on the bidirectional threaded rod.

[0019] As a further description of the above technical solution: The outer walls of the fixed plate are fixedly connected to connecting plates on both the left and right sides, and rubber pads are installed on adjacent sides of the outer walls of the two connecting plates.

[0020] The above technical solution involves using a connecting plate to install a rubber pad, which absorbs impact force through deformation, reducing collision intensity and minimizing accidental damage.

[0021] This utility model has the following beneficial effects: 1. In this utility model, when a pedestrian walks on a ramp, the buffer pad uses high elasticity to absorb the impact force and reduce the impact when falling. The support frame ensures that the buffer pad is stable and durable. The frame is initially fixed to the square groove by bolt one, and then bolt two is used to press down the spring to make the locking block flip, further stabilizing bolt one and ensuring that the device does not shift.

[0022] 2. In this utility model, when a pedestrian approaches, the dual-head motor starts, driving the connecting shaft and bevel gear one to rotate, which in turn causes bevel gear two and the bidirectional threaded rod to rotate. The threaded block moves accordingly, pushing connecting block one, connecting block two and connecting block three, so that the fixing plate moves up and down along the slide groove, realizing the adjustment of the handrail height, meeting the needs of different users, and ensuring the safety of pedestrians on the ramp.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of an urban barrier-free ramp buffer device, comprising a ramp body 1. Multiple columns 2 are equidistantly fixed to the left and right sides of the top wall of the ramp body 1. A buffer mechanism 3 is installed inside each column 2 to reduce the impact force when a pedestrian falls. A protective mechanism 4 is installed inside the ramp body 1 to provide additional protection. The buffer mechanism 3 includes a square groove 301, which is formed in the top wall of the ramp body 1. A support frame 302 is installed on the bottom wall of the square groove 301. The support frame 302 is made of aluminum alloy, which is lightweight and high-strength. A buffer pad 303 is installed on the top wall of the support frame 302. The buffer pad 303 is made of highly elastic rubber material. A fixing component 304 is installed at the top of the ramp body 1. The fixing component 304 includes a bolt 3041, which is threaded into the square groove 301. At the four corners of the bottom wall, bolt 3041 is threadedly connected to bolt 3042. A spring 3046 is installed at the bottom of bolt 3042. Square grooves 3043 are provided on the front and back sides of the lower middle part of the outer wall of bolt 3041. A locking block 3044 is rotatably connected to the inner wall of square groove 3043. Square grooves 3045 are provided around the lower middle part of the outer wall of bolt 3042. Rotating bolt 3042 on top of bolt 3041 causes it to move downward, compressing the bottom spring 3046. Square groove 3045 on bolt 3042 causes locking block 3044 to rotate in square groove 3043, causing locking block 3044 to flip outward, thereby further fixing bolt 3041 in square groove 301. The support frame 302 is threadedly connected to square groove 301 through bolt 3041. Locking block 3044 is located inside square groove 3045. Specifically, the buffer mechanism 3 is designed to reduce the impact force on pedestrians when they fall, while the protective mechanism 4 provides additional protection. When a pedestrian walks on a ramp, the buffer pad 303 absorbs the impact energy with its excellent elasticity, thereby reducing the impact force when the pedestrian falls. The support frame 302 ensures the stability and durability of the buffer pad 303. First, the support frame 302 is initially fixed in the square groove 301 by rotating the first bolt 3041. Then, the second bolt 3042 at the top of the first bolt 3041 is rotated to move it downward to compress the bottom spring 3046. The square groove 3045 on the second bolt 3042 causes the locking block 3044 to rotate in the square groove 3043, causing the locking block 3044 to flip outward, thereby further fixing the first bolt 3041 firmly in the square groove 301, ensuring that the entire device is stably fixed in the square groove 301 and preventing displacement.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The protective mechanism 4 includes two bidirectional threaded rods 401, both of which are located on the left and right sides inside the slope 1. Threaded blocks 402 are threadedly connected to the front and rear sides of the outer walls of the bidirectional threaded rods 401. A connecting block 403 is fixedly connected to the top wall of each threaded block 402, causing the threaded block 402 to move. A connecting block 404 is rotatably connected to the inner side of the outer wall of the connecting block 403, and a connecting block 405 is rotatably connected to the top of the connecting block 404. Fixing plates 406 are fixedly connected to the top walls of both connecting blocks 405. The connecting block 403 moves the connecting block 405 via the connecting block 404. A handrail 407 is installed on the top wall of the fixing plate 406. A drive assembly 408 is installed inside the slope 1, including a dual-head motor 4081. The dual-head motor 4081 is fixedly connected to... In the lower part of the inner wall of the slope 1, the output end of the double-head motor 4081 is fixedly connected to the connecting shaft 4082. The double-head motor 4081 drives the connecting shaft 4082 to rotate. The end of the connecting shaft 4082 is fixedly connected to the bevel gear 4083. The connecting shaft 4082 drives the bevel gear 4083 to rotate. The front side of the outer wall of the bevel gear 4083 is meshed with the bevel gear 4084. The bevel gear 4083 drives the bevel gear 4084 on the front side. The bevel gear 4084 is fixedly connected to the rear end of the outer wall of the double-threaded rod 401. The bevel gear 4084 drives the double-threaded rod 401 to rotate. The outer walls of multiple columns 2 are provided with sliding grooves 9 on adjacent sides. The sliding grooves 9 are slidably connected to the fixed plate 406. The sliding grooves 9 ensure that the fixed plate 406 can only slide up and down along the sliding grooves 9, ensuring the stability of the handrail 407 when it is raised, lowered or unfolded. Specifically, when a pedestrian approaches, the dual-head motor 4081 automatically starts. The dual-head motor 4081 drives the first bevel gear 4083 to rotate via the connecting shaft 4082, which in turn drives the second bevel gear 4084 on the front side. The second bevel gear 4084 drives the bidirectional threaded rod 401 to rotate, causing the threaded blocks 402 to move towards each other. The movement of the threaded blocks 402 drives the first connecting block 403, which in turn, through the second connecting block 404 and the third connecting block 405, pushes the fixing plate 406 to slide up and down along the groove 9 on the column 2. This series of actions ultimately enables flexible adjustment of the handrail 407's height to accommodate the gripping needs of pedestrians or wheelchair users of different heights, providing safe and stable support and protection for pedestrians on the ramp.

[0028] Reference Figure 2 and Figure 5 The inner bottom wall of the slope 1 is fixedly connected to the left and right sides of the slide rail 5. The inner wall of the slide rail 5 is slidably connected to the front and rear sides of the slide rail 5. The bottom wall of the threaded block 402 is fixedly connected to the top wall of the slide rail 6. The sliding connection between the slide rail 5 and the slide rail 6 ensures that the threaded block 402 moves horizontally only along the direction of the slide rail 5 when the bidirectional threaded rod 401 rotates. The slide rail 6 is used to support the weight of the threaded block 402 and reduce the load on the bidirectional threaded rod 401. The outer wall of the fixed plate 406 is fixedly connected to the left and right sides of the connecting plate 7. The connecting plate 7 is used to install rubber pads 8. Rubber pads 8 are installed on adjacent sides of the outer walls of the two connecting plates 7. The rubber pads 8 absorb the impact force through deformation, reduce the collision intensity, and reduce accidental damage. Specifically, the sliding connection between the slider 6 and the slide rail 5 ensures that the threaded block 402 moves horizontally only along the direction of the slide rail 5 when the bidirectional threaded rod 401 rotates. The slider 6 is used to support the weight of the threaded block 402 and reduce the load on the bidirectional threaded rod 401. The connecting plate 7 is used to install the rubber pad 8. The rubber pad 8 absorbs the impact force through deformation, reduces the collision intensity, and reduces accidental damage.

[0029] Working principle: When a pedestrian walks on a ramp, the buffer pad 303 absorbs the impact force through its high elasticity, reducing the impact force when the pedestrian falls. The support frame 302 ensures the stability and durability of the buffer pad 303. The support frame 302 is initially fixed in the square groove 301 by rotating the first bolt 3041. Then, the second bolt 3042 on top of the first bolt 3041 is rotated to move it downward, compressing the bottom spring 3046. The third square groove 3045 on the second bolt 3042 causes the locking block 3044 to rotate in the second square groove 3043, causing the locking block 3044 to flip outward, thereby further fixing the first bolt 3041 in the square groove 301. This can firmly fix the entire device in the square groove 301 and prevent displacement. When a pedestrian approaches, the dual-head motor 4081 is automatically activated. The dual-head motor 4081 drives the connecting shaft 4082 to rotate, which in turn drives the first bevel gear 4083 to rotate. The first bevel gear 4083 drives the second bevel gear 4084 on the front side, which in turn drives the bidirectional threaded rod 401 to rotate. The bidirectional threaded rod 401 drives the threaded block 402 to move in opposite directions. The threaded block 402 drives the first connecting block 403 to move, and the first connecting block 403 drives the third connecting block 405 to move through the second connecting block 404. The third connecting block 405 pushes the fixing plate 406 to slide up and down along the slide groove 9 on the column 2, ultimately achieving flexible adjustment of the height of the handrail 407 to meet the gripping needs of pedestrians or wheelchair users of different heights, providing safe and stable support and protection for pedestrians on the ramp.
