Description

Technical Field

[0001] This invention relates to the field of wheelchair technology, specifically to a wheelchair and assistive method for getting on and off a bus. Background Technology

[0002] People with disabilities face many challenges when using public transportation, one of which is the difficulty of getting on and off buses. To facilitate wheelchair access, existing buses are equipped with a manually openable mechanism on the passenger exit platform. Opening this mechanism creates a ramp between the bus and the ground, allowing accompanying persons to push the wheelchair safely into the bus. However, some bus routes do not have wheelchair access assistance devices due to their older models, and even newer buses with wheelchair access assistance devices still require a second person to assist in getting on and off the bus. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art, thereby providing a wheelchair assisting in getting on and off a bus and an assistive method thereof.

[0004] A wheelchair for assisting in getting on and off a bus includes: a frame body, a rear wheel assembly, an anti-tilt assembly, a front wheel assembly, and a mobility assembly;

[0005] The frame body has two pairs of vertically movable components on both sides, and front wheel components and rear wheel components are connected to the two pairs of movable components respectively. Multiple anti-tilt components are symmetrically arranged on both sides of the frame body.

[0006] The anti-tilt assembly includes a propeller motor, a motor mounting bracket, and a propeller; the propeller motor is fixed to the side of the frame body via the motor mounting bracket, and the output shaft of the propeller motor is fixed to the propeller.

[0007] Furthermore, the moving component includes a slide rail and a slider. The slide rail is fixed to the side of the frame body, the slider is slidably connected to the slide rail, and the slider is connected to the corresponding front wheel assembly or rear wheel assembly.

[0008] Furthermore, the front wheel assembly includes a front wheel motor and a front wheel, and the rear wheel assembly includes a rear wheel motor and a rear wheel;

[0009] The front wheel motor is fixedly connected to the corresponding slider, and the output shaft of the front wheel motor is fixedly connected to the front wheel. The rear wheel motor is fixedly connected to the corresponding slider, and the output shaft of the rear wheel motor is fixedly connected to the rear wheel.

[0010] Furthermore, the diameter of the rear wheel is larger than the diameter of the front wheel.

[0011] Furthermore, the wheelchair also includes multiple rollover detectors;

[0012] Multiple rollover detectors are fixed inside the main frame.

[0013] Furthermore, the wheelchair also includes multiple omnidirectional balls;

[0014] Multiple omnidirectional balls are evenly distributed at the bottom of the main frame.

[0015] Furthermore, the main frame body includes an upper front baffle, an upper side plate, a support plate, an upper rear baffle, a bottom plate, a lower front baffle, a lower rear baffle, and a lower side plate;

[0016] Both sides of the base plate are fixedly connected to lower side plates. The lower front baffle and the lower rear baffle are fixedly connected to the front side and the rear side of the base plate, respectively. The bottom of the support plate is fixedly connected to the top of the lower side plates, the lower front baffle and the lower rear baffle. Both sides of the support plate are fixedly connected to upper side plates. The front side and the rear side of the support plate are fixedly connected to the upper front baffle and the upper rear baffle, respectively.

[0018] Furthermore, the wheelchair also includes a controller that is electrically connected to the rear wheel assembly, the anti-tilt assembly, the front wheel assembly, and the mobility assembly.

[0019] A method for assisting in getting on and off a bus, the method being based on the wheelchair for assisting in getting on and off a bus described in any of the preceding claims, characterized in that it specifically comprises:

[0020] Reverse the wheelchair to the loading dock. Adjust the height of the wheelchair according to the height of the loading dock. Adjust the moving assembly so that the bottom of the frame is higher than the top surface of the loading dock. Then adjust the moving assembly so that the bottom of the frame is in contact with the top surface of the loading dock. At the same time, move the rear wheel assembly upwards until the bottom of the rear wheel assembly is higher than the bottom of the frame. Move the front wheel assembly towards the vehicle until 2 / 3 of the wheelchair is inside the vehicle. Move the front wheel assembly upwards until the bottom of the front wheel assembly is higher than the bottom of the frame. At the same time, move the rear wheel assembly downwards a short distance and then move the rest of the wheelchair into the vehicle.

[0021] When getting off the bus, the wheelchair moves towards the exit until the front wheel assembly is suspended in the air. At this point, the moving component drives the front wheel assembly to move downwards until the front wheel assembly contacts the ground. The front wheel assembly continues to drive the wheelchair forward until the rear wheel assembly is suspended in the air and the bottom of the frame body has not detached from the upper surface of the exit. At this point, the moving component drives the rear wheel assembly to move downwards until it contacts the ground. The wheelchair moves forward until the frame body separates from the bus.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] Please see Figures 1 to 3 A wheelchair for assisting in getting on and off a bus includes: a frame body, a rear wheel assembly 5, an anti-tilt assembly 7, a front wheel assembly 8, and a moving assembly 9;

[0040] Two pairs of vertically movable components 9 are provided on both sides of the main frame body. The front wheel assembly 8 and the rear wheel assembly 5 are respectively connected to the two pairs of movable components 9. Multiple anti-tilt components 7 are symmetrically arranged on both sides of the main frame body.

[0041] The anti-tilt assembly 7 includes a propeller motor, a motor mounting bracket, and a propeller; the propeller motor is fixed to the side of the frame body through the motor mounting bracket, and the output shaft of the propeller motor is fixed to the propeller. In this embodiment, a total of two pairs of anti-tilt assemblies 7 are provided.

[0042] When boarding a bus, back the wheelchair to the boarding gate and adjust its height according to the gate's height. Adjust the moving component 9 so that the bottom of the frame is higher than the top surface of the gate. Then, adjust the moving component 9 until the bottom of the frame contacts the top surface of the gate. Simultaneously, move the rear wheel assembly 5 upwards until its bottom is higher than the bottom of the frame. The front wheel assembly 8 then moves the wheelchair towards the inside of the bus until two-thirds of the wheelchair is inside. Move the front wheel assembly 8 upwards until its bottom is higher than the bottom of the frame. Simultaneously, move the rear wheel assembly 5 downwards a short distance, then move the remaining portion of the wheelchair into the bus.

[0043] When it is time to get off, follow the reverse procedure described above to complete the disembarkation. Move the wheelchair towards the exit until the front wheel assembly 8 is suspended in the air. At this point, the moving component 9 moves the front wheel assembly 8 downward until it contacts the ground. The front wheel assembly 8 continues to move the wheelchair forward until the rear wheel assembly 5 is suspended in the air and the bottom of the frame body has not detached from the upper surface of the exit. At this point, the moving component 9 moves the rear wheel assembly 5 downward until it contacts the ground. The wheelchair moves forward until the frame body separates from the bus. Finally, the moving component 9 moves the rear wheel assembly 5 and the front wheel assembly 8 to a suitable position.

[0044] In certain special circumstances, the wheelchair may tip over when getting on or off the bus. If this happens, the anti-tilt component 7 will activate, which means that multiple propellers at the bottom of the main frame will rotate simultaneously to generate upward lift, thereby keeping the wheelchair level and preventing it from falling.

[0045] When using this wheelchair to climb hills, it can continuously maintain the stability of the user's body. Simply adjust the moving component 9 according to the actual tilt level when going uphill or downhill, so that the front wheel component 8 or the rear wheel component 5 moves up or down until the user's seating area is flat.

[0046] Please continue reading. Figure 1 In this embodiment, the moving component 9 includes a slide rail and a slider. The slide rail is fixedly connected to the side of the frame body, and the slider is slidably connected to the slide rail. The slider is connected to the corresponding front wheel component 8 or rear wheel component 5. The movement of the front wheel component 8 or rear wheel component 5 can be achieved through the cooperation of the slide rail and the slider, and the movement is smooth and efficient.

[0047] Please continue reading. Figure 1 In this embodiment, the front wheel assembly 8 includes a front wheel motor and a front wheel, and the rear wheel assembly 5 includes a rear wheel motor and a rear wheel;

[0048] The front wheel motor is fixedly connected to the corresponding slider, and the output shaft of the front wheel motor is fixedly connected to the front wheel. The rear wheel motor is fixedly connected to the corresponding slider, and the output shaft of the rear wheel motor is fixedly connected to the rear wheel.

[0049] In this embodiment, the diameter of the rear wheel is larger than that of the front wheel. Having a larger rear wheel increases the stability of the wheelchair and reduces the risk of tipping over. A larger rear wheel provides a larger support area, making the wheelchair more stable. It also helps the wheelchair more easily traverse obstacles such as thresholds and uneven ground. Furthermore, a larger rear wheel provides greater ground clearance, making it easier for the wheelchair to navigate obstacles.

[0050] Please continue reading. Figure 3 In this embodiment, the wheelchair also includes multiple rollover detectors 12;

[0051] Multiple rollover detectors 12 are fixed inside the frame body. In this embodiment, a total of four rollover detectors 12 are used and are correspondingly set near the areas of the two pairs of anti-tilt components 7 in order to better detect whether tilting occurs. If tilting occurs, the rollover detector 12 sends a signal and the anti-tilt component 7 is activated.

[0052] Please continue reading. Figure 2 In this embodiment, the wheelchair also includes a plurality of omnidirectional balls 11;

[0053] Multiple omnidirectional balls 11 are evenly distributed at the bottom of the main frame. The multiple omnidirectional balls 11 allow the passenger to avoid direct contact with the bottom of the main frame when getting on and off the bus, instead contacting the omnidirectional balls 11, reducing friction and making the whole process faster and less strenuous.

[0054] Please continue reading. Figure 3 In this embodiment, the frame body includes an upper front baffle 1, an upper side plate 2, a support plate 3, an upper rear baffle 4, a bottom plate 6, a lower front baffle 10, a lower rear baffle 14, and a lower side plate 15.

[0055] Both sides of the base plate 6 are fixedly connected to the lower side plate 15. The lower front baffle 10 and the lower rear baffle 14 are fixedly connected to the front side and the rear side of the base plate 6, respectively. The bottom of the support plate 3 is fixedly connected to the top of the lower side plate 15, the lower front baffle 10 and the lower rear baffle 14. Both sides of the support plate 3 are fixedly connected to the upper side plate 2. The front side and the rear side of the support plate 3 are fixedly connected to the upper front baffle 1 and the upper rear baffle 4, respectively.

[0056] Please continue reading. Figure 3 In this embodiment, both the base plate 6 and the lower side plate 15 are provided with multiple lightweight through holes 13. Providing multiple lightweight through holes 13 without affecting overall performance further reduces the weight of the device and also reduces the working pressure on the anti-tilt component 7.

[0057] In this embodiment, the wheelchair also includes a controller, which is electrically connected to the rear wheel assembly 5, the anti-tilt assembly 7, the front wheel assembly 8, and the moving assembly 9. The controller can be manually controlled, and multiple detectors or sensors can be added around the wheelchair to automatically identify scenarios of getting on and off the vehicle or going uphill and downhill, and automatically make adjustments.

[0058] The present invention also includes a method for assisting in getting on and off a bus, the method being based on the wheelchair for assisting in getting on and off a bus described in any of the preceding claims, specifically as follows:

[0059] When boarding, back the wheelchair to the boarding opening. Adjust the height of the wheelchair according to the height of the boarding opening. That is, adjust the moving component 9 so that the bottom of the frame body is higher than the upper surface of the boarding opening. Then adjust the moving component 9 so that the bottom of the frame body contacts the upper surface of the boarding opening. At the same time, adjust the rear wheel assembly 5 to move upward until the bottom of the rear wheel assembly 5 is higher than the bottom of the frame body. The front wheel assembly 8 moves the wheelchair towards the inside of the vehicle until 2 / 3 of the wheelchair is inside the vehicle. The front wheel assembly 8 moves upward until the bottom of the front wheel assembly 8 is higher than the bottom of the frame body. At the same time, the rear wheel assembly 5 moves downward a short distance and then moves the rest of the wheelchair into the vehicle.

[0060] When it is time to get off, follow the reverse procedure described above to complete the disembarkation. Move the wheelchair towards the exit until the front wheel assembly 8 is suspended in the air. At this point, the moving component 9 moves the front wheel assembly 8 downward until it contacts the ground. The front wheel assembly 8 continues to move the wheelchair forward until the rear wheel assembly 5 is suspended in the air and the bottom of the frame body has not detached from the upper surface of the exit. At this point, the moving component 9 moves the rear wheel assembly 5 downward until it contacts the ground. The wheelchair moves forward until the frame body separates from the bus. Finally, the moving component 9 moves the rear wheel assembly 5 and the front wheel assembly 8 to a suitable position.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
