Description

Technical Field

[0001] This utility model belongs to the field of auxiliary devices, specifically relating to an auxiliary device for getting on and off a vehicle. Background Technology

[0002] Currently, in order to facilitate easy boarding and alighting for people with mobility impairments who are in wheelchairs, many types of boarding and alighting assistance devices have been promoted on the market to help people with mobility impairments enter and exit the vehicle while in wheelchairs, or to transfer people with mobility impairments from wheelchairs to seats inside the vehicle.

[0003] In the process of transferring people with mobility impairments from wheelchairs to seats in vehicles, for example, there is an existing vehicle entry and exit assistance device, which includes a fixed bracket and a boom movably connected to the fixed bracket. In use, the upper and lower ends of the fixed bracket are fixedly connected to the top and bottom of the vehicle compartment, the boom extends outward from the vehicle compartment, the wheelchair of the person with mobility impairment is pushed to the side of the vehicle, and the seat belt on the boom is fastened to the person with mobility impairment. Finally, the person with mobility impairment is transferred from the wheelchair to the corresponding seat in the vehicle through the lifting and retracting movement of the boom.

[0004] However, in actual use, the existing technology is only suitable for medium and large buses (the interior space of small cars is difficult to meet the installation requirements), and the installation and disassembly of the fixed bracket is very cumbersome and inconvenient. At the same time, during the transfer process, especially when the load is large, the force of the boom is transmitted to the fixed bracket, and the torque formed can easily cause deformation problems at the connection points of the top and bottom of the carriage. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a brand-new vehicle boarding and alighting assistance device.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A vehicle entry and exit assistance device includes a connecting bracket, a boom assembly movably connected to the connecting bracket and having a support head, a seat belt assembly connected to the support head, and a driver. The connecting bracket has locking slots spaced vertically and corresponding to the door hinges. As the wheelchair moves to any side of the door, the door opens and the hinges are exposed. The connecting bracket engages with the corresponding hinges from the locking slots and prevents the connecting bracket from rotating vertically. The person with mobility impairment is secured to the seat belt assembly. The driver drives the boom assembly and moves the person with mobility impairment between the wheelchair and the seat near the door.

[0008] According to a specific embodiment and preferred aspect of this utility model, the connecting bracket includes a vertically extending bracket body and a plurality of fastening modules disposed on one side of the bracket body and spaced vertically, wherein each fastening module is recessed from the bottom upward to form a fastening groove. This facilitates the hanging of the connecting bracket on the car door hinge from top to bottom, making operation simple and convenient.

[0009] Preferably, each fastening module is arranged perpendicularly to the bracket body, wherein the upper edge of the fastening module at the end away from the bracket body is bent downward to form a bent portion, and the bent portion is spaced from the lower edge of the fastening module at the end away from the bracket body to form a fastening groove. Here, the fastening groove is through on both sides, which can be used with various types of car door hinges on the market.

[0010] Preferably, the spacing between two adjacent fastening modules is adjustable. This allows for the matching of door hinges with different spacings to ensure precise installation.

[0011] Preferably, there are two fastening modules, wherein the upper fastening module is fixedly connected to the bracket body; the lower part of the bracket body has an adjustment groove extending vertically, and the lower fastening module is adjusted vertically along the adjustment groove by adjusting bolts.

[0012] According to another specific embodiment and preferred aspect of this utility model, the cross-section of the support body is rectangular; the support body has a plurality of first extension ears spaced vertically from the side away from the fastening module; a plurality of second extension ears corresponding one-to-one with the plurality of first extension ears are formed on one side of the boom assembly, and each second extension ear is vertically attached to the corresponding first extension ear and rotatably connected by a vertical pivot. Here, ensuring support is beneficial to improving the connection strength between the boom assembly and the support body; at the same time, after lifting the person with mobility impairment, the person with mobility impairment can be easily moved inside and outside the vehicle by manually rotating the boom assembly around the pivot centerline.

[0013] Preferably, at least one first extension ear is located between adjacent fastening modules, and the lines connecting the three form a triangle. This increases the stability of the overall structure.

[0014] Preferably, the boom assembly includes four booms forming a parallelogram, with one boom serving as a reference boom. A second extension lug is formed on the reference boom, and the upper and lower booms are rotatably connected to the reference boom from one end. The actuator includes a telescopic rod that drives the upper and lower booms to rotate synchronously up and down. The telescopic rod uses a hydraulic cylinder, which makes lifting people with mobility impairments easier.

[0015] Preferably, a sleeve is provided on the arm opposite to the reference rod, and the load-bearing head is connected to the sleeve and rotatably configured around the vertical center line. Here, the reference rod and the load-bearing head are rotatably configured, which increases the range of motion of the load-bearing head and meets the needs of people with mobility difficulties getting in and out of the vehicle in any door opening space.

[0016] In addition, the support head includes a frame pole and multiple hooks mounted on the frame pole and connected to form a polygon; the safety harness assembly includes multiple safety harnesses that can be combined to support a person with mobility impairments. During transfer, the multiple safety harnesses are hooked onto the hooks from one end. It should be noted that before transfer, the multiple safety harnesses should be wrapped around the torso of the person with mobility impairment, and then the ends of the multiple safety harnesses should be hooked onto the hooks for transfer. As for the combination of safety harnesses, it can be adjusted according to the actual physical condition of the person with mobility impairment to achieve a safe fixation.

[0017] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] Existing technologies are only suitable for medium and large passenger buses (the interior space of small cars is difficult to accommodate installation), and the installation and disassembly of the fixed brackets are cumbersome and inconvenient. Furthermore, during transfer, especially under heavy loads, the torque generated by the force transmitted from the boom to the fixed brackets can easily cause deformation at the connection points at the top and bottom of the passenger compartment. This application, however, provides a holistic design for the boarding / alighting assistance device, cleverly addressing the shortcomings and defects of existing technologies. With this device, when boarding, any door is opened to expose the door hinges, and the connecting brackets are then engaged with the various hinges of the door. A person with mobility impairment can sit in a wheelchair and be pushed onto the bus. Next to the door, the person with mobility impairment is secured to the seatbelt assembly. Then, the boom assembly is driven by a actuator to transfer the person from the wheelchair to a seat near the door. After use, the seatbelt assembly is unfastened, and the connecting bracket and boom assembly are removed for future use. For assisted alighting, the corresponding door is opened, exposing the door hinges. The connecting bracket is engaged with each hinge of the door. The wheelchair is pushed to the door, and the person with mobility impairment is secured to the seatbelt assembly. Then, the boom assembly is driven by a actuator to transfer the person from the seat to the wheelchair. After use, the seatbelt assembly is unfastened, and the connecting bracket and boom assembly are removed for future use. Therefore, compared with existing technologies, this utility model utilizes the exposed hinges of the open door. By installing the connecting bracket at the door hinges, the movement of the boom assembly assists the person with mobility impairment secured to the seatbelt assembly in getting on and off the vehicle. This not only provides a more spacious operating area, is applicable to any type of vehicle, and is highly practical, but also allows for simple and convenient assembly and disassembly, without causing deformation of the vehicle cabin during use.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0029] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] like Figures 1 to 3 As shown, the vehicle boarding and alighting assistance device involved in this embodiment includes a connecting bracket 1, a boom assembly 2 movably connected to the connecting bracket 1 and having a load-bearing head t, a safety belt assembly connected to the load-bearing head t, and a driver 3.

[0031] Specifically, the connecting bracket 1 has interlocking slots c0 that are spaced vertically and correspond one-to-one with the door hinges. As the wheelchair moves to any door M, the door M opens and the hinge J is exposed. The connecting bracket 1 engages with each hinge J through the corresponding interlocking slots c0, preventing the connecting bracket 1 from flipping up and down. That is, this application utilizes the high strength of the door hinges to achieve quick assembly and disassembly of the connecting bracket 1.

[0032] The connecting bracket 1 includes a vertically extending bracket body 10 and multiple fastening modules 11 disposed on one side of the bracket body 10 and spaced vertically. Each fastening module 11 is recessed from the bottom upward to form a fastening groove c0. This facilitates the connection bracket to be hung on the door hinge from top to bottom, making the operation simple and convenient.

[0033] In some specific embodiments, each fastening module 11 is arranged perpendicularly to the bracket body 10, wherein the upper edge of the fastening module 11 at the end away from the bracket body 10 is bent downward to form a bent portion 110, and the bent portion 110 is spaced from the lower edge of the fastening module 11 at the end away from the bracket body 10 to form a fastening groove c0. Here, the fastening groove is through on both sides, which can be used with various types of car door hinges on the market.

[0034] For ease of implementation, the spacing between two adjacent fastening modules 11 is adjustable. This allows for the matching of door hinges with different spacings to ensure precise installation.

[0035] In some specific embodiments, there are two fastening modules 11, wherein the upper fastening module 11 is fixedly connected to the bracket body 10; the lower part of the bracket body 10 forms an adjustment groove c1 extending vertically, and the lower fastening module 11 is adjusted vertically along the adjustment groove c1 by adjusting bolts s. That is, after the lower fastening module 11 is adjusted vertically along the adjustment groove c1 to a suitable height, the adjusting bolts s are tightened to fix the lower fastening module 11.

[0036] In this example, the cross-section of the support body 10 is rectangular. Two first extension ears e1, spaced vertically apart, are formed on the side of the support body 10 away from the fastening module. Two second extension ears e2, corresponding one-to-one with the two first extension ears e1, are formed on one side of the boom assembly. Each second extension ear e2 is vertically attached to its corresponding first extension ear e1 and is rotatably connected via a vertical pivot z. This ensures support and improves the connection strength between the boom assembly and the support body. Furthermore, after lifting a person with mobility impairments, they can easily move inside and outside the vehicle by manually rotating the boom assembly around the pivot centerline.

[0037] To further facilitate implementation, a first extension ear e1 is located between two fastening modules 11 in the vertical direction, and the line connecting the three forms a triangle. In other words, the force-bearing point of the first extension ear e1 and the force-bearing points of the two fastening modules 11 form a triangle. This increases the stability of the overall structure.

[0038] In some specific embodiments, the boom assembly 2 includes four booms 20 that are rotatably connected to each other and form a parallelogram. One boom 20 serves as a reference rod, on which a second extension lug e 2 is formed. The upper and lower booms 20 are rotatably connected to the reference rod from one end and can drive the boom 20 opposite the reference rod to rotate up and down. The quadrilateral structure facilitates folding and saves space.

[0039] Meanwhile, the second extension ear e2 passes through the reference rod and is located below the upper or lower arm 20 to form a limit during the downward flipping of the upper and lower arms 20. In this embodiment, when the upper and lower arms 20 are flipped to the horizontal, the upper arm 20 abuts against the second extension ear e2.

[0040] Meanwhile, a sleeve 200 is provided on the arm 20 opposite to the reference rod, and the bearing head t is connected to the sleeve 200 and rotates around the vertical center line. Here, the reference rod and the bearing head are rotatably set, which increases the range of motion of the bearing head and meets the needs of people with mobility difficulties getting in and out of the vehicle in any door opening space.

[0041] The bearing head t in this embodiment includes a frame rod t0, multiple hooks t1 arranged on the frame rod t0 and connected to form a polygon, and a rotating arm t2 rotatably connected between the frame rod t0 and the sleeve 200. There are three hooks t1, which are respectively arranged at both ends and the middle of the frame rod t0.

[0042] In this example, the safety harness assembly (not shown in the diagram, but easily understood) includes multiple safety harnesses that can be combined to support a person with mobility impairments. During the transfer, the multiple safety harnesses are attached to multiple hooks t1 from one end. It is important to note that before the transfer, the multiple safety harnesses are looped around the torso of the person with mobility impairment, and then the ends of the harnesses are attached to the hooks for the transfer. The arrangement of the safety harnesses can be adjusted according to the actual physical condition of the person with mobility impairment (refer to common safety harnesses in daily life) to achieve a secure fixation.

[0043] In this example, the actuator 3 includes a telescopic rod 30 that drives the upper and lower arms 20 to rotate synchronously up and down. The two ends of the telescopic rod 30 are rotatably connected between the reference rod and the lower arm 20, and are used to lift the person with mobility impairment after the seat belt is used to secure them. The telescopic rod uses a hydraulic cylinder and its telescopic movement is controlled by a handheld controller, making it easier to lift the person with mobility impairment.

[0044] In other words, when the person with mobility impairment is secured to the seat belt assembly, the drive unit 3 drives the boom assembly 2 and lifts the person with mobility impairment from the wheelchair or the seat near the door. Then, the person with mobility impairment can be moved into or out of the vehicle by manually rotating the boom assembly 2. Finally, the drive unit 3 drives the boom assembly 2 downward to place the person with mobility impairment on the seat or wheelchair near the door.

[0045] In summary, after adopting this vehicle entry and exit assistance device, when assisting with entry, open any door and expose the door hinges, then engage the connecting bracket with each hinge of the door. The person with mobility impairment sits in the wheelchair and is pushed to the door. The person with mobility impairment is then secured to the seat belt assembly. Next, the drive unit activates the boom assembly, transferring the person with mobility impairment from the wheelchair to a seat near the door. After use, the seat belt assembly is unfastened, and the connecting bracket and boom assembly are removed for future use. When assisting with exit, open the corresponding door and expose the door hinges, engage the connecting bracket with each hinge of the door, push the wheelchair to the door, and secure the person with mobility impairment to the seat belt assembly. Next, the drive unit activates the boom assembly, transferring the person with mobility impairment from the seat to the wheelchair. After use, the seat belt assembly is unfastened, and the connecting bracket and boom assembly are removed for future use. Therefore, compared with the prior art, this utility model utilizes the exposed hinges of the open car door and installs the connecting bracket at the door hinge. Based on the movement of the boom assembly, it assists people with mobility impairments who are fixed to the seat belt assembly to get on and off the vehicle. This not only provides a more spacious operating space and is applicable to any type of vehicle, making it highly practical, but also makes disassembly and assembly simple and convenient, and does not cause deformation of the vehicle body during use.

[0046] The present invention has been described in detail above, but it is not limited to the embodiments described above. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the protection scope of the present invention.
