[0023] 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.

[0024] Example 1

[0025] like Figures 1-6 As shown in the figure, a vertical lift boarding vehicle for disabled persons that can lock to a wheelchair includes a fixed base 1 and a boarding structure mounted on the fixed base 1. The boarding structure includes a fixing component and a lifting component.

[0026] The fixed assembly includes a support 2, a balance plate 5, a lifting seat 6, an inclined plate 7, a first motor 8, a bottom drive wheel 9, a double-acting screw 10, a limit rod 11, a wheel groove 12, a bottom transmission belt 13, a bottom driven wheel 14, and a vehicle body 23. The support 2 is fixedly installed on the top of the fixed base 1. The balance plate 5 is installed parallel to the right side of the support 2. The lifting seat 6 is fixedly installed on the right side of the balance plate 5. The inclined plate 7 is installed at the right end of the lifting seat 6. The first motor 8 is fixedly installed at the rear of the lifting seat 6. The bottom drive wheel 9 is installed at the output end of the first motor 8. The bottom transmission belt 13 is installed on the side of the bottom drive wheel 9. The bottom driven wheel 14 is installed at the other end of the bottom transmission belt 13. The double-acting screw 10, which is coaxial with the bottom drive wheel 9, is installed in front of the output end of the first motor 8. The limit rod 11 is engaged on the left and right sides of the double-acting screw 10. Two sets of symmetrical wheel grooves 12 are opened on the surface of the lifting seat 6. The fixed base 1 is fixedly installed on the vehicle body 23 below.

[0027] The lifting assembly includes a balance groove 3, a balance slider 4, a lifting screw 15, two side through grooves 16, a balance bar 17, a connecting rod 18, a top driven wheel 19, a top transmission belt 20, a top driving wheel 21, and a second motor 22. Two sets of balance grooves 3 are provided on the right side of the support 2. Two sets of balance sliders 4 are fixedly installed on the left side of the balance support plate 5 at positions corresponding to the balance grooves 3. The lifting screw 15 is fixedly installed in the middle of the support 2. Two sets of side through grooves 16 are provided on the front and rear sides inside the support 2. Two sets of balance bars 17 are fixedly installed at the rear of the support 2. A connecting rod 18 is slidably installed on the right side of the balance bar 17. The connecting rod 18 is fixed to the balance support plate 5. The top driven wheel 19 is installed on the top of the lifting screw 15. The top transmission belt 20 is installed behind the top driven wheel 19. The top driving wheel 21 is installed on the other side of the top transmission belt 20. The second motor 22 is installed at the bottom of the top driving wheel 21.

[0028] The limiting rod 11 forms a translation structure with the lifting seat 6 through the bidirectional screw 10. Two sets of limiting rods 11 are installed above the bidirectional screw 10. The first motor 8 drives the bidirectional screw 10 to rotate. Since the limiting rods 11 are symmetrically installed on the left and right sides of the bidirectional screw 10, the limiting rods 11 will translate in relative directions through the bidirectional screw 10. After the user sits on the lifting seat 6 in the wheelchair, the wheels of the wheelchair will enter the wheel groove 12. Then, the wheels of the wheelchair will be locked and limited by the four sets of limiting rods 11 moving towards the center, thereby fixing the wheelchair.

[0029] Two sets of bidirectional screws 10 are installed. The two sets of bidirectional screws 10 form a rotating structure through the bottom driven wheel 14 and the bottom transmission belt 13. The bottom driven wheel 14 forms a transmission structure through the bottom transmission belt 13 and the bottom driving wheel 9. During use, the two sets of bidirectional screws 10 installed in parallel can simultaneously adjust and control the four sets of limit rods 11. The first motor 8 drives the bottom driving wheel 9 to rotate. Then, the bottom driving wheel 9 drives the bottom driven wheel 14 to rotate through the bottom transmission belt 13. Then, a set of bidirectional screws 10 is set in front of the bottom driven wheel 14 and the bottom driving wheel 9. Therefore, the two sets of bidirectional screws 10 will rotate synchronously, which makes it convenient to lock the wheels at the same time and prevent the wheelchair from moving above the lifting seat 6.

[0030] Example 2

[0031] like Figures 1-4 As shown, this embodiment further explains Example 1. The balance support plate 5 forms a lifting structure with the support 2 through the cooperation between the connecting rod 18 and the lifting screw 15. The balance support plate 5 forms a sliding structure with the balance rod 17 through the connecting rod 18. The lifting screw 15 rotates through the top driven wheel 19. Since the connecting rod 18 and the lifting screw 15 are meshed with each other, the rotation of the lifting screw 15 will drive the connecting rod 18 to rise and fall inside the device. Since the connecting rod 18 and the balance support plate 5 are fixed to each other, the balance support plate 5 will drive the right lifting seat 6 to rise and fall synchronously, which facilitates the upward movement of the wheelchair above the lifting seat 6 to help the user board the plane.

[0032] The balance support plate 5 forms a translation structure with the support 2 through the cooperation between the balance slider 4 and the balance groove 3. The balance support plate 5 also forms a sliding structure through the balance slider 4 and the balance groove 3. During use, in order to maintain balance, two sets of balance grooves 3 are provided on the right side of the support 2 during the lifting and lowering process of the balance support plate 5. Then, the balance slider 4 on the rear side of the balance support plate 5 can slide and lift inside the balance groove 3. The balance slider 4 and the balance rod 17 cooperate with each other to improve the stability of the balance support plate 5 during lifting and lowering, and prevent the balance support plate 5 from tilting inside the device.

[0033] The lifting screw 15 forms a rotating structure through the cooperation between the top driven wheel 19 and the top transmission belt 20. The top driven wheel 19 forms a transmission structure through the cooperation between the top transmission belt 20 and the top driving wheel 21. The second motor 22 drives the top driving wheel 21 to rotate. Then, the top driving wheel 21 drives the side top driven wheel 19 to rotate through the top transmission belt 20, thereby driving the lifting screw 15 to rotate and driving the lifting seat 6 to rise and fall.

[0034] In use: After the user sits on the lifting seat 6 in a wheelchair, the wheels of the wheelchair will enter the wheel groove 12. The first motor 8 drives the bidirectional screw 10 to rotate. The two sets of bidirectional screws 10 installed in parallel can simultaneously adjust and control the four sets of limit rods 11. The first motor 8 drives the bottom drive wheel 9 to rotate. Then, the bottom drive wheel 9 drives the bottom driven wheel 14 to rotate through the bottom transmission belt 13. Then, a set of bidirectional screws 10 is set in front of the bottom driven wheel 14 and the bottom drive wheel 9. So the two sets of bidirectional screws 10 will rotate synchronously, which can lock the wheels at the same time and prevent the wheelchair from moving on the lifting seat 6. Since the limit rods 11 are symmetrically installed on the left and right sides of the bidirectional screws 10, the limit rods 11 will enter through the bidirectional screws 10. The wheelchair is moved in a relative direction and then locked and limited by four sets of limit rods 11 moving towards the center, thereby fixing the wheelchair. Then, the second motor 22 drives the top drive wheel 21 to rotate, and the top drive wheel 21 drives the side driven wheel 19 to rotate through the top transmission belt 20, thereby driving the lifting screw 15 to rotate and driving the lifting seat 6 to rise and fall. The lifting screw 15 rotates through the top driven wheel 19. Since the connecting rod 18 and the lifting screw 15 are meshed with each other, the rotation of the lifting screw 15 will drive the connecting rod 18 to rise and fall inside the device. Since the connecting rod 18 and the balance plate 5 are fixed to each other, the balance plate 5 will drive the right lifting seat 6 to rise and fall synchronously, which facilitates the upward movement of the wheelchair above the lifting seat 6 to help the user board the plane.
