DETAILED DESCRIPTION

[0024] In order to further understand the structure, features and other purposes of the present invention, the preferred embodiments are described in detail with reference to the accompanying drawings as follows. The embodiments described in the drawings are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.

[0025] like Figure 1 As shown, Figure 1It is a structural schematic diagram of the convenient walking device of the present invention; the convenient walking device includes a driving walking mechanism 1, a sitting chair 2 and a control unit 3.

[0026] Combination Figure 2 and Figure 3 The driving walking mechanism 1 includes a servo motor 11, a worm gear reducer 12, a walking gear row 13, a high-precision linear guide 14 and a walking slide 15, wherein the walking gear row 13 and the high-precision linear guide 14 are fixedly arranged on the sliding track along the direction of the stair handrail, and the walking slide 15 is slidably connected to the high-precision linear guide 14, and the cross-section of the walking slide 15 perpendicular to the walking gear row 13 is S-shaped. The servo motor 11 and the worm gear reducer 12 are fixed on the top of the walking slide 15, and the output end of the servo motor 11 is connected to the input end of the worm gear reducer 12. The output end of the worm gear reducer 12 is provided with a walking gear 121, and the walking gear 121 is meshed with the walking gear row 13. When the servo motor 11 is started, it can drive the walking slide 15 to slide along the high-precision linear guide 14, thereby providing power for the movement of the passenger chair 2.

[0027] The servo motor 11 used in the present invention to provide power can improve the comfort of passengers when walking. At the same time, the servo motor 11 has high stability. The servo motor 11 is equipped with a turbine reducer 12 to enhance the walking torque. In addition, the turbine reducer 12 has a self-locking feature. In the event of a sudden power outage, there is no danger of the riding mechanism automatically sliding down, which greatly improves safety.

[0028] The present invention also uses a traveling gear 121 and a traveling gear row 13 to replace the lead screw or wire in a common walking device, thereby solving the problem that the lead screw cannot increase the speed. When the lead screw itself is long, it is easy to cause insufficient mechanical rigidity and produce shaking, resulting in reduced comfort, increased noise and affected service life. The wire rope power traction is prone to breakage, causing the riding mechanism to automatically slide down and cause safety accidents.

[0029] Preferably, two high-precision linear guides 14 are provided, and the sliding rails are arranged in an L-shape. One high-precision linear guide 14 is provided on the horizontal surface of the sliding rail, and another high-precision linear guide 14 is provided on the vertical surface of the sliding rail, so that the high-precision linear guides 14 are arranged in an L-shape, and the side and bottom of the walking skateboard 15 are respectively slidably connected to the two high-precision linear guides 14, so that the sliding of the walking skateboard 15 is more stable and safer to use.

[0030] Combination Figure 1 and Figure 3The passenger chair 2 includes a support plate 21, a safety handrail 22, a safety seat plate 23 and an automatic safety pedal 24; the support plate 21 is vertically fixed to the side of the walking skateboard 15 away from the high-precision linear guide rail 14. When the walking skateboard 15 slides along the high-precision linear guide rail 14, it drives the support plate 21 to slide. The length direction of the support plate 21 remains vertical and its thickness direction is perpendicular to its sliding direction. For ease of disassembly and assembly, a seat connecting flange 151 is provided on one side of the walking skateboard 15, and the support plate 21 is fixed by the seat connecting flange 151.

[0031] Two safety armrests 22 are horizontally fixed on both sides of the top of the support plate 21. The two ends of the safety armrests 22 are placed on both sides of the support plate 21 for easy holding with both hands. A hand-push walking switch 221 is provided on the safety armrests 22. The hand-push walking switch 221 is electrically connected to the control unit. When the walking switch is pushed by the user, the servo motor 11 starts to drive the seat 2 to move. It has the advantages of easy opening and stopping and strong operability.

[0032] The safety board 23 is installed in the middle of the support plate 21 through a horizontally arranged first hinge axis, so that the safety board 23 is hinged to the support plate 21, and the safety board 23 rotates 90 degrees around the first hinge axis. A notch with the same width as the safety board 23 is provided on the support plate 21 above the safety board 23, and the safety board 23 rotates 90 degrees to the notch around the first hinge axis, and an avoidance notch is provided at the end of the safety board 23 away from the first hinge axis, so that the safety board 23 can be manually rotated to choose whether to use it. More preferably, the safety board 23 is provided on both sides of the support plate 21, and the two safety boards 23 are respectively hinged on both sides of the width direction of the support plate 21, and the axes of the hinge axes of the two safety boards 23 coincide. By providing two safety boards 23, it is convenient for users to choose the facial orientation according to different situations.

[0033] The automatic safety pedal 24 is arranged at the bottom of the support plate 21. The automatic safety pedal 24 is arranged horizontally and is installed at the bottom of the support plate through a horizontally arranged second hinge shaft. The automatic safety pedal 24 rotates 90° around the second hinge shaft. A accommodating groove is opened at a position of the support plate 21 below the safety riding plate 23. The shape and size of the accommodating groove match the shape and size of the automatic safety pedal 24, so that when the automatic safety pedal 24 is not in use, the automatic safety pedal 24 can be rotated 90° to be placed in the accommodating groove to save space.

[0034] When the passenger presses the start button, the convenient walking device automatically puts down the automatic safety pedal 24. The support plate 21 is provided with a riding safety check sensor 212 between the safety riding plate 23 and the automatic safety pedal 24. The riding safety check sensor 212 is electrically connected to the control unit 3. The riding safety check sensor 212 is an infrared sensor. The sensing position of the riding safety check sensor 212 is within the width range of the automatic safety pedal 24. Therefore, the automatic safety pedal 24 can only be started and used when the passenger stands at the designated position of the automatic safety pedal 24, thereby increasing its safety. More preferably, the upper surface of the automatic safety pedal 24 is provided with two limit grooves 242 of the same size. The length direction of the limit grooves 242 is perpendicular to the support plate 21, and the arrangement direction of the limit grooves 242 is along the width direction of the support plate 21, which can facilitate the user to determine his standing position and play an anti-slip role. Front and rear anti-collision switches 241 are provided at the front and rear ends of the automatic safety pedal 24. The front and rear anti-collision switches 241 are provided in grooves 243 provided on the side of the automatic safety pedal 24. The front and rear anti-collision switches 241 are electrically connected to the control unit 3 to avoid danger when the passenger seat 2 collides with obstacles in front and behind. To further increase the safety of the convenient mobility device, a safety belt 211 is provided at the position below the safety handrail 22 of the support plate 21 to ensure the safety of the passenger when the passenger has physical conditions or external unsafe factors during the ride.
