Technical Field

[0001] This utility model relates to the technical field of stairwell elevators, and in particular to a stairwell elevator pedal flipping structure. Background Technology

[0002] With the development of technology, people's lives have gradually improved. Many old residential areas did not have elevators installed before, which made it inconvenient for the elderly to go up and down the stairs. Therefore, many families have installed stairwell mobility aids to make it easier for the elderly to go up and down the stairs. When the stairwell mobility aid is in operation, it needs to be equipped with a drive system to drive the stairwell mobility aid and realize the normal up and down movement of the stairwell mobility aid to meet the needs of users.

[0003] Some stairwell mobility aids typically use a single structure, resulting in poor pedal storage and a tendency to take up valuable stairwell space. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a stairwell elevator pedal flipping structure to solve the problems of poor pedal rotation effect and occupation of stairwell space in existing stairwell elevators.

[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figure 1-5As shown, a stairwell elevator pedal flipping structure includes a base 11, which is the main structure of the stairwell elevator. The back of the base 11 is connected to the track, and the front of the base 11 is connected to a pedal 12, which is used to support the user. The user is located on the pedal 12 and moves with the base 11.

[0025] The pedal 12 is rotatably mounted below the base 11. The base 11 has a propulsion structure inside, which is connected to the pedal 12 and controls the pedal 12 to flip from a horizontal state to a vertical state. When the pedal 12 is working, it is in a horizontal state, and when it is not working, the pedal 12 flips to a vertical state.

[0026] An L-shaped connecting rod 13 is connected to the bottom of the base 11. A connecting groove 14 is provided at one end of the pedal 12 near the connecting rod 13. The vertical part of the connecting rod 13 is fixedly connected to the base 11, and the horizontal part of the connecting rod 13 extends into the connecting groove 14. The connecting rod 13 is rotatably connected to the pedal 12 in the connecting groove 14.

[0027] To ensure the stability of the pedal 12 in a horizontal state, a limiting block 15 is fixedly connected to the side wall of the base 11. The limiting block 15 is located on one side of the connecting rod 13 and above the pedal 12. When the pedal 12 is flipped to a horizontal position, it abuts against the limiting block 15.

[0028] Meanwhile, the base 11 has a drive cavity 16 inside, and a propulsion structure is provided inside the drive cavity 16. A crank 17 is connected to the propulsion structure. One end of the crank 17 is connected to the propulsion structure, and the other end of the crank 17 is connected to the pedal 12. The movement of the crank 17 can control the flipping operation of the pedal 12.

[0029] Furthermore, the base 11 has an opening on the lower side of the drive cavity 16, and the end of the crank 17 extends out from the opening of the drive cavity 16. The crank 17 is rotatably connected to the side wall of the pedal 12. When the crank 17 moves up and down under the action of the propulsion structure, the crank 17 can drive the pedal 12 to rotate around the connection of the connecting rod 13, thereby realizing the switching between vertical and horizontal states.

[0030] The propulsion structure is used to control the movement of the crank 17. The propulsion structure includes a pump 18, which is fixedly installed on the inner wall of the drive chamber 16. The pump 18 is connected to a telescopic rod 19. One end of the telescopic rod 19 is fixedly connected to the pump 18, and the other end of the pump 18 is connected to the crank 17, thereby realizing the driving operation of the crank 17.

[0031] In another embodiment, the propulsion structure may also be a motor, which is fixedly installed on the inner wall of the drive cavity 16. The output shaft of the motor is fixedly connected to a gear, and a rack is slidably installed on the inner wall of the drive cavity 16. The rack and the gear are meshed and connected. The end of the rack is connected to the crank 17 to realize the driving operation of the crank 17.

[0032] Furthermore, the crank 17 has a movable hole 20 at the end away from the pedal 12, and a connecting rod 21 is inserted through the movable hole 20. The connecting rod 21 is fixedly connected to the propulsion structure. The connecting rod 21 can be installed on the telescopic rod 19 or the rack. By pushing the connecting rod 21 to move, the crank 17 is propelled to move, which improves the adaptability of the crank 17 and makes assembly more convenient.

[0033] Furthermore, the movable hole 20 is an elongated, waist-shaped hole, and the connecting rod 21 is slidably installed inside the movable hole 20, which provides clearance space for the connecting rod 21 during the process of pushing the crank 17 to move, and prevents it from popping up quickly.

[0034] Furthermore, a spring 22 is mounted on the crank 17 near the connecting rod 21, along with a baffle 23. The baffle 23 is located between the spring 22 and the connecting rod 21. After the connecting plate 21 abuts against the baffle 23, it compresses the spring 22. The baffle 23 prevents the connecting rod 21 from slipping. The spring 22 can achieve a buffering effect during the pushing process, slowing down the flipping speed of the pedal 12.

[0035] The base 11 also has a control cavity 24, which is located at the center of the base 11. The drive cavity 16 is located on one side of the control cavity 24. The control cavity 16 is equipped with a control module and a battery. The propulsion structure is electrically connected to the control module and the battery. The control module is used to control the battery to supply power to the propulsion structure.

[0036] The pedal 12 is provided with a receiving cavity 25 with openings on both sides. A baffle 26 is slidably connected to the pedal 12 at the receiving cavity 25. The baffle 26 seals the opening. At the same time, a return spring 27 is provided in the receiving cavity 25 of the pedal 12. The return spring 27 is connected to the baffle 26 and the inner wall of the receiving cavity 25. When the pedal 12 comes into contact with the outside, the baffle 26 makes contact first to achieve a protective effect and prevent accidents caused by collisions.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
