Description

Technical Field

[0001] This utility model relates to the field of telescopic pedal technology, and in particular to an electric telescopic pedal device for enclosed sightseeing vehicles. Background Technology

[0002] In recent years, the tourism industry has experienced rapid growth, with a continuous increase in the number of tourists visiting scenic spots and theme parks across the country. Meanwhile, urban sightseeing tourism has become increasingly popular, leading to a surge in sightseeing routes in cities. Against this backdrop, enclosed sightseeing vehicles, as an important mode of transportation for tourists, are seeing their usage frequency and scope expand, placing higher demands on vehicle comfort and convenience. The continuous development of automotive electronics, motor drive technology, and materials science has provided strong technical support for the research and application of electric retractable pedals for enclosed sightseeing vehicles. High-performance motors provide stable power, ensuring rapid and smooth pedal extension and retraction. Advanced controllers control the motor's operation, enabling synchronized operation of the pedals and door opening and closing, and feature intelligent obstacle detection and gravity sensing functions, improving safety and reliability. Furthermore, the application of new aluminum alloys and other materials ensures the pedals are lighter and more corrosion-resistant while maintaining strength, further enhancing their overall performance and lifespan.

[0003] The mechanism of the electric retractable step device for enclosed sightseeing vehicles includes a step mechanism, a retractable drive mechanism, a guide mechanism, a motor control mechanism, a mounting and fixing mechanism, and a protective mechanism. To ensure good maneuverability and accommodate equipment such as batteries, enclosed sightseeing vehicles have a high chassis, which means passengers need to traverse a significant height difference when getting on and off. This poses a challenge and safety hazard, especially for children and the elderly. To improve the passenger experience and meet the needs of different passenger groups, the electric retractable step device automatically extends when passengers get on and off, providing a convenient platform and reducing the difficulty of getting on and off. However, the use of chain drive and direct drive methods is prone to impact and vibration, which not only affects the lifting and lowering effect of the step but also leads to premature wear of components and reduces the overall lifespan of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an electric telescopic pedal device for enclosed sightseeing vehicles, which aims to improve the existing technology that uses chain drive and direct drive, which is prone to impact and vibration. This not only affects the lifting and lowering effect of the pedal, but also causes premature wear of parts and reduces the service life of the entire device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an enclosed sightseeing vehicle electric retractable pedal device, comprising a carrier shell, a support platform fixedly connected to the bottom inner side of the carrier shell, a support frame one fixedly connected to the top right side of the support platform, a motor two fixedly connected to the top left side of the support platform, a small gear fixedly connected to the output end of the motor two, a large gear meshing with the outer wall of the small gear, a short strip fixedly connected to the top front side of the large gear, a long strip rotatably connected to the bottom of the short strip, a support frame two rotatably connected to the top of the long strip, the outer wall of the support frame two slidingly connected to the inner wall of the support frame one, a foot pedal fixedly connected to the top of the support frame two, a support plate fixedly connected to the bottom left side of the foot pedal, and a rotating mechanism provided inside the carrier shell for convenient use by passengers.

[0006] As a further description of the above technical solution:

[0007] The rotating mechanism includes a motor, the right side of which is fixedly connected to the inner right end of the bearing shell. A short plate is fixedly connected to the output end of the motor. A second short plate is rotatably connected to the front side of each of the two first short plates. A mounting block is rotatably connected to the front side of each second short plate. A wide plate is fixedly connected between adjacent mounting blocks. A rotating shaft is fixedly connected to the rear side of the wide plate. The outer wall of the rotating shaft is rotatably connected to the inner front end of the bearing shell.

[0008] As a further description of the above technical solution:

[0009] A protective pad is fixedly connected to the inner middle of the bearing shell, and a nameplate is fixedly connected to the top front side of the bearing shell.

[0010] As a further description of the above technical solution:

[0011] Two breathing lights are fixedly connected to the front side of the carrier shell, and both breathing lights adopt a symmetrical design.

[0012] As a further description of the above technical solution:

[0013] A protective cover is fixedly connected to the bottom of the foot pedal, and the outer wall of the protective cover is slidably connected to the top of the supporting shell.

[0014] As a further description of the above technical solution:

[0015] A sign is fixedly connected to the front of the protective cover, and an anti-slip groove is provided on the top of the foot pedal.

[0016] As a further description of the above technical solution:

[0017] A heat dissipation plate is fixedly connected to the rear side of the support shell, and an anti-slip pad is fixedly connected to the top front side of the support shell.

[0018] As a further description of the above technical solution:

[0019] The top of the wide plate is provided with an anti-slip groove, and reflective strips are provided on both the left and right sides of the top of the wide plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotation of the small gear is driven by the second motor, which in turn drives the rotation of the large gear meshing with it. The rotation of the short bar drives the long bar to push the second support frame up and down along the first support frame, so that the foot pedal can achieve the lifting effect. This avoids the impact and vibration during the power transmission process. At the same time, the connection structure between the short and long bars and the guiding effect of the first support frame ensure that the foot pedal can remain stable during the lifting process, thus ensuring the safety and comfort of passengers when getting on and off the vehicle.

[0022] 2. In this utility model, the first motor drives the first short plate to rotate, the rotation of the first short plate causes the second short plate to rotate, and the rotation of the second short plate pulls the moving mounting block, so that the wide plate can be retracted through the rotating shaft. When passengers arrive, it can be lowered again, which further facilitates the ride of the sightseeing vehicle. The retraction and lowering of the wide plate can be flexibly adjusted according to different vehicle models, passenger flow and usage scenarios to meet diverse usage needs.
