[0002] The boarding vehicle for passengers with limited mobility is a type of airport equipment designed specifically to help people with limited mobility get on and off aircraft without obstacles. It includes key components such as the service brake system, steering system, and hydraulic system. Its design and manufacturing must comply with strict national standards and technical requirements, thereby providing passengers with limited mobility with more convenient and safe boarding services.

[0003] The service brake system should be able to ensure that the vehicle and its load can be stopped reliably under any operating conditions, even in the event of hydraulic failure. The maximum free travel of the steering wheel should not exceed the angle specified in the standard. The hydraulic system should be able to maintain normal operation under various operating conditions and have good sealing performance.

[0004] In the existing technical solutions, the chassis of the common disabled passenger boarding car is relatively high, and the distance between the car and the ground is large. A hydraulic lifting platform is required to lift the disabled passengers from the ground to the car. The structure is complex, the cost is high, and there are safety hazards, which increases maintenance costs.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] A small low-floor boarding vehicle for passengers with limited mobility comprises a vehicle body 1, the front end of the vehicle body 1 being fixedly connected to a vehicle head 11, the rear end of the vehicle body 1 being fixedly connected to a vehicle tail 12, the interior of the vehicle body 1 being movably connected to a box body 2, the left and right ends of the box body 2 being fixedly connected to a frame 9, the left end of the box body 2 being movably connected to a box door 3, the upper end of the box body 2 being movably connected to a lifting device 6, the front end of the box body 2 being movably connected to a front platform 5, the box body 2 being embeddable in the chassis of the vehicle body 1, and the box body 2 being embedded in the chassis of the vehicle body 1. The bottom of the box 2 is close to the bottom of the vehicle body 1, and the box 2 slides and fits inside the vehicle body 1. The lifting device 6 is located on the front side of the inner wall of the box 2, and the lifting device 6 slides and fits inside the inner wall of the box 2. The lower left end of the box 2 is hinged with a boarding plate 4. A limiting block 7 is provided at the lower end of the interior of the vehicle body 1, and the number of the limiting blocks 7 is multiple. A limiting groove 21 is correspondingly provided at the lower end of the box 2, and the lower ends of the front 11 and the rear 12 are both provided with support legs 10, and the number of the support legs 10 is multiple.

[0028] By adopting the above technical solution, the driver enters the front of the vehicle 11, drives the vehicle body 1 to the vicinity of the passenger plane, controls the multiple legs 10 to descend, supports the vehicle body 1, the front of the vehicle 11 and the rear of the vehicle 12, aligns the front platform 5 with the boarding gate, and flips the boarding plate 4 open to reveal the door 3 on one side of the box body 2. The flipped boarding plate 4 is tilted when it contacts the ground. At this time, the assistant pushes the wheelchair of the person with limited mobility into the box body 2, and then activates the lifting device 6 at the upper end of the box body 2 to make the limit block 7 leave the limit slot 21. As the lifting device 6 rises, the box body 2 is lifted up. The box body 2 rises together with the people inside. At the same time, after the box body 2 slides over the upper end of the car body 1, the interior of the box body 2 is connected with the front platform 5. After the box body 2 and the front platform 5 are stable, the assistant pushes the wheelchair of the person with limited mobility into the passenger aircraft. Then the assistant can return to the inside of the box body 2 through the front platform 5, and exit through the box door 3 at the front end of the box body 2 as the box body 2 descends, so as to lower the vehicle chassis and make the car close to the ground by changing the layout of the lifting mechanism. The car can be boarded directly with a ramp, and there is no need to set up a lifting device 6. The structure is simple, the cost is low, and there is no safety hazard.

[0029] Specifically, such as Figure 4 As shown, the vehicle body 1 is U-shaped, with a beam 8 fixedly connected between the front 11 and the rear 12. Necessary components such as a pump, a motor and a battery are arranged inside the vehicle body 1, and frames 9 are fixedly connected to the left and right ends of the box body 2.

[0030] By adopting the above technical solution, the vehicle body 1 is first reduced in size as a whole, and the interior of the box body 2 is reduced to a size that can accommodate one or two passengers with limited mobility and their assistants. Then, the front 11 and the rear 12 of the vehicle are fixed by the beam 8, and the frame 9 is provided for protective fixation, thereby reducing the size of the entire vehicle, reducing the space occupied by the vehicle, saving energy, and reducing manufacturing and maintenance costs.

[0031] Working principle: The driver drives the vehicle body 1 to the vicinity of the passenger plane, controls the multiple legs 10 to descend, supports the vehicle body 1, the front 11 and the rear 12, aligns the front platform 5 with the boarding gate, and flips the boarding board 4 open to reveal the door 3 on one side of the box 2. The flipped boarding board 4 is tilted when it contacts the ground. At this time, the assistant pushes the wheelchair of the person with mobility difficulties into the box 2, and then starts the lifting device 6 at the upper end of the box 2 to make the limit block 7 leave the limit groove 21. As the lifting device 6 rises, the box 2 and the people inside rise together. At the same time, after the box 2 slides the upper end of the vehicle body 1, the interior of the box 2 is connected with the front platform 5. After the box 2 and the front platform 5 are stable, the assistant pushes the wheelchair of the person with mobility difficulties into the passenger plane.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
