Description

Technical Field

[0001] This utility model relates to the field of public transportation auxiliary equipment technology, specifically a quick-loading and unloading wheelchair ramp device for public transportation. Background Technology

[0002] The wheelchair ramp for buses is an auxiliary device designed to help wheelchair passengers get on and off buses quickly and safely.

[0003] In the existing technology, the ramp plate is composed of a top plate and a bottom plate. It is usually fixed to the bus door by welding or bolting. Welding makes the ramp plate a rigid structure that cannot be disassembled, and it cannot be flexibly used or stored according to actual needs. While bolting provides disassembly, it requires frequent tightening and loosening operations. Neither of these methods can meet the actual needs of convenient and efficient bus operation, and their practicality is poor. Utility Model Content

[0004] The purpose of this invention is to provide a quick-loading and unloading wheelchair ramp device for public transportation, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-loading and unloading wheelchair ramp device for public transportation, comprising a base plate, a connecting block rotatably connected to the base plate, and a top plate rotatably connected to the connecting block;

[0006] The base plate is provided with an adjustment mechanism, which includes a mounting groove and two mounting rods. A lifting plate is slidably connected inside the mounting groove. A main magnet is fixedly connected to the bottom end of the lifting plate. Symmetrically arranged pressing rods are fixedly connected to the bottom end of the lifting plate. A secondary magnet is fixedly connected to the bottom end inside the mounting groove. Limit blocks are slidably connected to each mounting rod. A support block is fixedly connected to the bottom end of each limit block. A guide rod is fixedly connected to each support block. A spring is fixedly connected to each support block at the position corresponding to the guide rod. A handle is fixedly connected to the top end of the lifting plate.

[0007] Preferably, the mounting groove is located in the middle of the base plate, and the mounting rods are symmetrically and fixedly connected to the bottom end of the base plate.

[0008] Preferably, the bottom of the main magnet is set as the south pole, the top of the secondary magnet is set as the north pole, and the main magnet and the secondary magnet are magnetically connected.

[0009] Preferably, the bottom end of each extrusion rod is triangular, and the bottom end of each extrusion rod passes through the main magnet, the auxiliary magnet, and is slidably connected to the base plate inside the corresponding mounting rod.

[0010] Preferably, one end of each limiting block slides through the outer wall of the corresponding mounting rod, and one end of each guide rod slides through the outer wall of the corresponding mounting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the use of the adjustment mechanism allows the ramp plate device to completely get rid of the limitations of the traditional fixing method. It eliminates the need for rigid fixing by welding and also eliminates the frequent tightening and loosening of bolts. It not only realizes the flexible loading and unloading of the ramp plate and solves the pain points of welded structures being unable to be disassembled, difficult to store, and easy wear and loosening of bolt connection threads, but also greatly improves the operating efficiency, significantly shortens the loading and unloading time, and adapts to the needs of efficient bus operation. At the same time, it reduces the operating threshold and labor intensity. Staff can easily operate it without professional tools or complex skills, which fundamentally improves the practicality of the device in the bus scenario. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution:

[0020] Example 1: A quick-loading and unloading wheelchair ramp device for public transportation includes a base plate 1, a connecting block 2 rotatably connected to the base plate 1, and a top plate 3 rotatably connected to the connecting block 2;

[0021] When in use, the top plate 3 can be rotated directly. The top plate 3 can be rotated through the support of the connecting block 2 and the bottom plate 1. Then, the top plate 3 is rotated to contact the ground, at which point the wheelchair can be moved into the bus through the top plate 3.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: an adjustment mechanism 4 on the base plate 1, the adjustment mechanism 4 including a mounting groove 41 and two mounting rods 42, a lifting plate 43 slidably connected inside the mounting groove 41, a main magnet 44 fixedly connected to the bottom end of the lifting plate 43, symmetrically arranged pressing rods 45 fixedly connected to the bottom end of the lifting plate 43, a secondary magnet 46 fixedly connected to the bottom end inside the mounting groove 41, a limit block 47 slidably connected to each of the mounting rods 42, a support block 48 fixedly connected to the bottom end of each limit block 47, a guide rod 49 fixedly connected to each of the support blocks 48, a spring 401 fixedly connected to each of the support blocks 48 at the position corresponding to the guide rod 49, and a handle 402 fixedly connected to the top end of the lifting plate 43;

[0023] The mounting slot 41 is located in the middle of the base plate 1. The mounting rods 42 are symmetrically fixed to the bottom of the base plate 1. The bottom of the main magnet 44 is set as the south pole, and the top of the auxiliary magnet 46 is set as the north pole. The main magnet 44 and the auxiliary magnet 46 are magnetically connected. The bottom of the pressing rods 45 are all triangular. The bottom of the pressing rods 45 all penetrate the main magnet 44 and the auxiliary magnet 46 and are slidably connected to the base plate 1 inside the corresponding mounting rod 42. One end of the limiting block 47 slides through the outer wall of the corresponding mounting rod 42. One end of the guide rod 49 slides through the outer wall of the corresponding mounting rod 42.

[0024] In use, the mounting rod 42 at the bottom of the base plate 1 is inserted through the threaded hole pre-drilled in the bottom layer of the bus. Then, the lifting plate 43 is held by the handle 402 and connected to the mounting groove 41. The lifting plate 43 will drive the pressing rod 45 through the auxiliary magnet 46 and the corresponding mounting rod 42 on the base plate 1. Then, the pressing rod 45 will slide into the interior of the corresponding mounting rod 42. At this time, the triangular part of the downward-moving pressing rod 45 will press the arc-shaped part of the limiting block 47. At this time, the pressure on the arc-shaped part of the limiting block 47 inside the mounting rod 42 will act on the limiting block 47 itself. The limiting block 47 will protrude outward from the mounting rod 42. The movement of the limiting block 47 will drive the support block 48 and the guide rod 49 to move together. During the movement, the support block 48 will compress and retract the corresponding spring 401. At this time, the top of the limiting block 47 will abut against the bottom of the bottom layer of the bus. Figure 3At this point, the lifting plate 43 is completely moved into the mounting slot 41, and the main magnet 44 and auxiliary magnet 46 at the bottom of the lifting plate 43 are also magnetically connected. At this point, the base plate 1 is fixed and the loading is completed. When disassembling, simply pull the lifting plate 43 from the mounting slot 41 by pulling the handle 402. At this point, the main magnet 44 and auxiliary magnet 46 are separated, and the lifting plate 43 will drive the pressing rod 45 to separate from the mounting rod 42. At this point, the limiting block 47 will be reset to the inside of the mounting rod 42 under the action of the spring 401. At this point, the base plate 1 is released and can be directly removed from the bottom of the bus. Loading and unloading are very convenient.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
