[0020] This utility model discloses an auxiliary mechanism for getting on and off a tricycle for disabled passengers, comprising a base plate 101 and an auxiliary assembly for getting on and off. The auxiliary assembly includes two lifting structures 102, a load-bearing component 103, two connecting frames 104, and two tilting components 105. The lifting structure 102 includes a support component 106, a lifting driven bracket 107, and a driving component 108. The support component 106 includes a support seat 109 and a lifting base 110.

The load-bearing component 103 includes a lifting platform 113, two limit locks 114, an extension plate 115, and a limit spring buckle 116. The tilting component 105 includes a tilting link 117 and a tilting spring 118. The aforementioned solution solves the problem that existing tricycles for disabled passengers do not have an auxiliary lifting structure for getting on and off, which requires multiple people to lift the wheelchair, making it very inconvenient for disabled passengers to ride.

[0021] In this specific embodiment, the base plate 101, in conjunction with the vehicle boarding and alighting assistance components, enables disabled persons to conveniently board and alight from the vehicle.

[0022] The two lifting structures 102 are respectively located on one side of the base plate 101; the support member 106 is disposed on one side of the base plate 101; the lifting driven bracket 107 is fixedly connected to the support member 106 and is located on one side of the support member 106; the driving member 108 is disposed between the support member 106 and the lifting driven bracket 107; the load-bearing member 103 is respectively disposed between the two lifting driven brackets 107; the two connecting frames 104 are respectively fixedly connected to the load-bearing member 103 and are respectively located on both sides of the load-bearing member 103; the two tilting members 105 are respectively disposed on one side of the two connecting frames 104; and the base plate 101 is fixed by locking bolts and other fixing components. When mounted on a passenger tricycle, for assisting disabled passengers to board, the drive unit 108 is controlled to extend the lifting driven bracket 107 on the support member 106. Then, the flipping member 105 is controlled to flip and unfold the load-bearing member 103. Subsequently, the wheelchair of the disabled person moves onto the load-bearing member 103, and the drive unit 108 is controlled to lift and raise the disabled person and wheelchair into the passenger tricycle. Finally, the flipping member 105 is controlled to flip the load-bearing member 103 to close the rear of the passenger tricycle. This solves the problem that existing passenger tricycles do not have a lifting and lowering structure for disabled passengers, which requires multiple people to lift the wheelchair when the disabled person is riding in the tricycle, making it very inconvenient for the disabled person to ride.

[0023] Secondly, the support base 109 is fixedly connected to the base plate 101 and is located on one side of the base plate 101; the lifting base 110 is fixedly connected to the support base 109 and is located on one side of the support base 109, and the support base 109 cooperates with the lifting base 110 to support the assembly of the lifting driven bracket 107.

[0024] Furthermore, the hydraulic jacking cylinder 111 is fixedly connected to the support base 109, and the output end of the hydraulic jacking cylinder 111 is fixedly connected to the lifting driven bracket 107 and located on one side of the support base 109; the hydraulic oil pipe 112 is connected to the hydraulic jacking cylinder 111 and located on one side of the hydraulic jacking cylinder 111, and the hydraulic oil pipe 112 is connected to the hydraulic oil supply equipment. The hydraulic jacking cylinder 111 is driven by the impact of hydraulic oil to achieve the effect of driving the lifting driven bracket 107.

[0025] In addition, the lifting platform 113 is rotatably connected to the two lifting driven brackets 107 and is located between the two lifting driven brackets 107; the two limiting locks 114 are fixedly connected to the lifting platform 113 and the two lifting driven brackets 107 respectively, and are located on both sides of the lifting platform 113; the extension plate 115 is rotatably connected to the lifting platform 113 and is located on one side of the lifting platform 113; the limiting spring buckle 116 is fixedly connected to the lifting platform 113 and is located on one side of the lifting platform 113. The lifting platform 113 is extended and retracted through the lifting driven brackets 107 and the limiting locks 114. Then, the limiting spring buckle 116 is operated to release the extension plate 115, and then the extension plate 115 is unfolded to facilitate the movement of the wheelchair of the disabled onto the lifting platform 113.

[0026] Furthermore, the flipping link 117 is fixedly connected to the connecting frame 104, and the output end of the flipping link 117 is fixedly connected to the lifting driven bracket 107 and located on one side of the connecting frame 104; the flipping spring 118 is fixedly connected to the flipping link 117 and the lifting driven bracket 107 respectively, and is located between the flipping link 117 and the lifting driven bracket 107 respectively, and the flipping link 117 cooperates with the flipping spring 118 to flip the lifting platform 113.

[0027] When using this utility model, the base plate 101 is assembled onto the passenger tricycle by fixing components such as locking bolts. When assisting disabled people to board the vehicle, the hydraulic oil pipe 112 is connected to the hydraulic oil supply equipment. The hydraulic oil drives the hydraulic cylinder 111 to extend the lifting driven bracket 107. Then, the flipping linkage 117, in conjunction with the flipping spring 118, flips and unfolds the lifting platform 113. The limit spring buckle 116 is then operated to release the extension plate 115, allowing the wheelchair of the disabled person to move onto the lifting platform 113. The hydraulic cylinder is then controlled to drive the lifting driven bracket 107 to lift and raise the disabled person and wheelchair into the passenger tricycle. Finally, the flipping linkage 117 is controlled to flip the lifting platform 113 to close the rear of the passenger tricycle. This solves the problem that existing passenger tricycles do not have a lifting structure for disabled people, thus requiring multiple people to lift the wheelchair, making it very inconvenient for disabled people to ride.
