Adjustable walker for the elderly

Abstract

This invention discloses an adjustable mobility scooter for the elderly, comprising a body, a seat, a control compartment, and a shock-absorbing assembly. The control compartment contains a first adjustment component and a second adjustment component connected to the shock-absorbing assembly. The first adjustment component, driven by the reciprocating motion of the shock-absorbing assembly, cools the control compartment. The second adjustment component is connected to the first adjustment component and simultaneously adjusts the height of the seat. This allows the seat height to be adjusted according to the bumpy road conditions, thereby lowering the elderly person's center of gravity and preventing them from falling off the seat. The stronger the bump, the lower the seat. Furthermore, the scooter can simultaneously utilize both water cooling and air cooling for power supply based on the bump conditions. The reciprocatingly oscillating fan also prevents dust from entering the scooter body; the stronger the bump, the better the heat dissipation.

Description

Technical Field

[0001] This invention relates to the field of mobility scooters, and more particularly to an adjustable mobility scooter for the elderly. Background Technology

[0002] Elderly mobility scooters are low-speed electric vehicles, also known as four-wheeled electric mobility scooters. They are a type of transportation that has emerged in recent years, mainly targeting elderly people who travel for leisure, picking up and dropping off children, shopping, and other similar purposes. However, due to their low price, ease of operation, and relatively low safety risks, elderly mobility scooters have gained popularity among many consumers.

[0003] Elderly mobility scooters inevitably encounter bumpy roads during operation. Since the height of the conventional seat cannot be adjusted while driving, the higher center of gravity makes it easier for elderly people to fall off the seat, especially on bumpy roads. Furthermore, the vibration of the vehicle can put a strain on the battery, causing it to overheat. Summary of the Invention

[0028] Reference Figure 1-11 As shown, an adjustable mobility scooter for the elderly includes a vehicle body 1, a seat 2, a control compartment 3, and a shock-absorbing component. The control compartment 3 is provided with a first adjustment component and a second adjustment component connected to the shock-absorbing component. The first adjustment component is used to cool the control compartment 3 under the reciprocating drive of the shock-absorbing component. The second adjustment component is connected to the first adjustment component and simultaneously adjusts the height of the seat 2.

[0029] The shock absorption assembly is located at the rear of the vehicle body 1, specifically behind the control compartment 3. The shock absorption assembly is a traditional shock absorber, including a shock absorber rod 4. During driving, the shock absorber rod 4 will reciprocate according to the road conditions. The more bumpy the road, the faster the reciprocating speed and the farther the reciprocating distance. A top rod 5 is provided on the side of the shock absorber rod 4, parallel to the shock absorber rod 4.

[0030] The first adjustment mechanism includes a reversing mechanism, a driving mechanism, and a cooling mechanism. The reversing mechanism converts the longitudinal reciprocating force of the shock absorber 4 into a lateral force. The reversing mechanism includes a reversing chamber 6 located on one side of the shock absorber 4. The reversing chamber 6 contains a first chamber 7 and a second chamber 8. A first sealing plate 9 is located inside the first chamber 7. A first spring 10 is located from the lower surface of the first sealing plate 9 to the bottom surface of the first chamber 7. A groove 57 for the passage of the top rod 5 is located at the bottom of the first chamber. To prevent the top rod 5 from accidentally colliding with the bottom surface of the first chamber, a guide edge can also be provided. A second sealing plate 11 is located inside the second chamber 8. A top column 12 is located below the second sealing plate 11. An arc-shaped spring 13 is located below the second chamber 8. The two ends of the arc-shaped spring 13 are straight segments, and the middle is an arc segment. The other end of the arc spring 13 is connected to one end of the guide cylinder 14. A guide rod 16 is provided inside the guide cylinder 14, and a movable ball 15 is provided inside the arc spring 13. The top rod 5 presses the first sealing plate 9, causing the top column 12 below the second sealing plate 11 to press the movable ball 15 inside the arc spring 13. This causes the movable ball 15 to press the guide rod 16 inside the guide cylinder 14 synchronously, and the guide rod 16 moves laterally.

[0031] To prevent the guide rod 16 from damaging the first sealing part, a rubber block 68 is provided on the top surface of the guide rod 16. The guide rod 16 is a certain distance away from the sealing plate. This arrangement is to ensure that the normal reciprocating motion of the top rod 5 during normal driving will not cause pressure on the first sealing plate 9.

[0032] The driving mechanism includes a driving tube 17, with a continuous, spirally wound arc-shaped guide groove 18 on the inner wall of the driving tube 17. A guide rod 16 is aligned with the driving tube 17. A guide block 56, shaped like a round block, is provided on the lower surface of the front end of the driving rod 16. When the guide rod 16 moves forward, the driving tube 17 rotates through the engagement of the guide block 56 with the arc-shaped guide groove 18. A first gear is fixedly installed at the other end of the driving tube 17.

[0033] 19. The drive tube 17 is rotated to drive the first gear 19 to rotate. A second gear 20 and a third gear 21 are respectively meshed on the upper part and slightly to the sides of the first gear 19. A fourth gear 22 is also meshed above the second gear 20 and the third gear 21. At the same time, the second gear 20 and the third gear 21 are provided with a mechanism for pulling the second gear.

[0034] A pulling device that disengages the second gear 20 and the third gear 21 from the first gear 19, the pulling device including a movable rod 23, one end of the movable rod 23 being placed in a bearing 24 in the middle of the second gear 20 / third gear 21, and the other end being disposed on an arc-shaped block.

[0035] Within the arc-shaped block 25, the arc of the arc-shaped block 25 is concentric with that of the fourth gear 22. A second spring 26 connected to the movable rod 23 is provided within the arc-shaped block 25, and a first pull rope 28 is provided on the movable rod 23, passing through the second spring.

[0036] 26 is connected to a control box 27 located at the outer end of the arc-shaped block 25. A magnetic suction element 29 is provided in the control box 27 near the arc-shaped block 25, and a fixed electromagnet 30 is provided at a distance away. A switch structure for controlling the opening and closing of the electromagnet 30 is provided below the guide rod 16.

[0037] like Figure 11 As shown, a groove 57 is provided below the guide rod 16, and a rack 58 is provided in the groove 57. The switch structure includes a fifth gear 59 disposed below and meshing with the rack 58.

[0038] A gear post 60 is provided on the fifth gear 59. A lever 61 is rotatably mounted at the other end of the gear post 60. A circumferentially evenly spaced protruding edge 62 is provided at the other end of the gear post 60, and a circumferentially evenly spaced concave edge 63 is provided at the center hole of the lever 61. The lever 61 is placed within a U-shaped groove. A first switch 65 and a second switch 66 are provided on both sides of the U-shaped groove. The first switch 65 controls the on / off state of the electromagnet 30 on the second gear 20, and the second switch 66 controls the on / off state of the electromagnet 30 on the third gear 21. When the lever 61 is not subjected to any other force, the cooperation of the protruding edge 62 and the concave edge 63 allows the fifth gear 59 to drive the lever 61 to press against either the first switch 65 or the second switch 66. When the first switch 65 and the second switch 66 can no longer be pressed, under the action of plastic deformation, the protruding edge...

[0039] 62 can disengage from the concave edge 63, but will continue to press the first switch 65 or the second switch 66. When the guide rod 16 moves back, it will cause the dial 61 to press the switch on the other side, and at the same time, it can press the switch on this side.

[0040] Initially, the dial 61 is located in the middle of the first switch 65 and the second switch 66. A straight groove 67 is provided at the front end of the arc-shaped guide groove 18. The guide block 56 first passes through the straight groove 67 and then enters the arc-shaped guide groove 18. This arrangement is to allow time for the dial 61 to contact the first switch 65. Optimally, the rack 58 and the fifth gear 59 can be configured to engage more quickly, making this contact time negligible.

[0041] A power supply 31 for power supply is provided in the control chamber 3. The cooling mechanism includes a water-cooling cooling mechanism connected to the first gear 19 and an air-cooling cooling mechanism connected to the second gear 20. The water-cooling cooling mechanism includes a heat dissipation water pipe 32 wrapped around the outside of the power supply 31. Two connecting pipes of the heat dissipation water pipe 32 are connected to two sides of the water-driving chamber 33. The water-driving chamber 33 is used to make the water in the heat dissipation water pipe 32 flow back and forth to remove the heat from the surface of the power supply 31. A first water-driving wheel 34 and a second water-driving wheel 35 are installed vertically inside the water-driving chamber 33. The second water-driving wheel 35 is placed underwater and the first water-driving wheel 34 is placed above the water. The two are meshed. At the same time, the first water-driving wheel 34 is connected to the first gear 19 and rotates back and forth with the first gear 19, driving the water in the heat dissipation water pipe 32 to flow.

[0042] The air-cooled cooling mechanism includes a drive rod 36 connected to the fourth gear 22. A drive wheel 37 is provided at the end of the drive rod 36. A fixed sleeve 38 is wrapped around the drive tube 17. Two sets of support rods 39 are provided on the fixed sleeve 38. A rotating rod 40 is provided at the end of the support rod 39, passing through the two sets of support rods 39. A swing member 41 is provided on the rotating rod 40. A guide post 42 is provided at one end of the swing member 41 facing downwards from the drive wheel 37, and a fan plate 43 is provided at the other end. A movable sleeve 44 is provided on the drive wheel 37, and a sleeve 45 is provided at the end of the movable sleeve 44. The sleeve 45 is located inside the guide post 42. When the drive wheel 37 follows the drive rod 36... During rotation, the movable sleeve 44 extends and retracts on the drive wheel 37, while the sleeve 45 moves within the guide post 42. The faster the drive wheel 37 rotates, the stronger the fan action of the fan plate, increasing gas flow within the control chamber and further cooling the power supply. Simultaneously, the fan plate can blow dust from the control chamber 3 to the outside, effectively preventing dust adsorption. The rotational speed of the drive wheel 37 is related to the fourth gear 22, which in turn is related to the speed of the guide rod 16 towards the drive wheel 37. The reciprocating speed of the shock absorber 4 directly controls the movement speed of the guide rod 16. Similarly, the bumpier the road surface, the faster the fan operates.

[0043] The second adjustment assembly includes a first bevel gear 46 disposed on the drive rod 36, a second bevel gear 47 meshing with the first bevel gear 46, a rotating rod 48 disposed on the second bevel gear 47, a second pull rope 49 disposed on the rotating rod 48, and a ball 50 disposed at the end of the second pull rope 49, with a side of the ball 50 facing the ball.

[0044] An arc-shaped plate 51 in the 50-degree direction is fixed on a damper 52. The arc-shaped plate 51 is connected to a slider 54 on a sliding rheostat 53. The sliding rheostat 53 is connected to a motor 55 below the seat 2.

[0045] The length of the motor 55 rod extending from the motor 55 is related to the current. Initially, the resistance value output by the sliding rheostat 53 is the smallest, and the height of the motor 55 rod is the highest. As the road becomes bumpy, the output resistance of the sliding rheostat 53 increases, and the seat 2 will decrease in height. The bumpier the road surface, the larger the angle between the ball 50 and the rotating rod 48, so that the ball 50 can move the arc plate 51 further away from the rotating rod 48. In order to prevent the arc plate 51 from returning to its original position quickly, the damper 52 is provided on one side of the arc plate 51.

[0046] The working process of this invention is as follows: During normal driving, the push rod 5 will not compress the first sealing plate 9. When driving on a bumpy road, the frequency and amplitude of each reciprocating movement of the push rod 5 are directly determined according to the bumpiness of the road surface. The push rod 5 compresses the first sealing plate 9, and through the reversing mechanism, the guide rod 16 causes the drive tube 17 to rotate. The rack 58 cooperates with the fifth gear 59 to make the dial plate 61 continuously compress the first switch 65. The electromagnet 30 on the second gear 20 is energized, causing the second gear 20 to disengage from the first gear 19. The first gear 19 reciprocates, and the water-driving chamber 33 controls the flow. The surface of the power supply 31 is cooled. When the guide rod 16 returns, the rack 58 and the fifth gear 59 cooperate to make the dial plate 61 press the second switch 66, thereby causing the second gear 20 to re-mesh with the first gear 19, and the third gear 22 to disengage from the first gear 19. At this time, the fourth gear 22 moves in one direction. The fan plate 43 can fan the power supply 31, increase airflow, reduce temperature, and effectively prevent dust from entering the control chamber 3. At the same time, the output resistance of the sliding rheostat 53 is controlled by the cooperation of the ball 50 and the arc plate 51, thereby controlling the height of the seat 2.

[0047] The above description is merely one embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, equivalent changes, or alterations made without departing from the technical solution of the present invention shall fall within the protection scope of the present invention.
