Description

Telescopic pedal structure

Technical Field

The utility model relates to a special type car footboard technical field particularly, relates to a flexible footboard structure.

Background

Along with the technical development of fire fighting equipment, a fireman puts forward a new requirement on the convenience of vehicle operation, and the requirements on humanized design and rationality of vehicle equipment are higher and higher. The telescopic pedal device can realize linkage operation of the roller shutter door and the pedal, saves opening time and is convenient to use.

The fire engine footboard form that the existing market is mostly convertible footboard, and the structural feature of this kind of footboard is: the turnover pedal is driven by an air spring, the pedal fixing frame is connected with the turnover pedal through a fixing pin, one end of the air spring is connected with the pedal fixing frame through a connecting pin, and the other end of the air spring is connected with the turnover pedal through a connecting pin. When the pedal is used, the pedal needs to be turned down by manpower, the process needs to be manually controlled, otherwise, the phenomenon of in-place impact exists, the connecting structure is complex, the turning process is labor-consuming, and the turning process needs to sweep a large space.

SUMMERY OF THE UTILITY MODEL

To the problem among the correlation technique, the utility model provides a flexible footboard structure solves current draw bail complicacy, the hard problem of artificial upset process.

In order to achieve the technical purpose, the technical scheme of the utility model is as follows:

the utility model provides a flexible footboard structure, includes flexible step frame, flexible step frame slidable sets up on the footboard fixing base, be provided with electric pull rod on the flexible step frame, electric pull rod sets up the intermediate position of footboard fixing base, the one end of electric pull rod is passed through the connecting pin and is set up on the footboard fixing base, the other end of electric pull rod is in through the fixed setting of connecting pin on the flexible step frame.

Furthermore, tracks are arranged on two sides of the pedal fixing seat, and the telescopic treadle frame is in telescopic motion on the guide rail.

Furthermore, the two sides of the telescopic step frame are provided with sliding blocks, and the sliding blocks are arranged in the tracks in a sliding mode.

Further, the electric pull rod is a driving unit.

The utility model has the advantages that: the electric pull rod and the pedal move on the same plane, the electric pull rod can convert the rotation of the driving motor into the telescopic movement of the pedal, the structure is simple, the installation is convenient, and meanwhile, the whole process can also prevent the phenomenon of in-place impact.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in fig. 1-5, a flexible footboard structure, including flexible step 4, flexible step 4 slidable sets up on footboard fixing base 1, be provided with electric pull rod 2 on the flexible step 4, electric pull rod 2 sets up the intermediate position of footboard fixing base 1, the one end of electric pull rod 2 is passed through connecting pin 3 and is set up on the footboard fixing base 1, the other end of electric pull rod 2 is in through connecting pin 31 fixed the setting on the flexible 4 frames of marking time.

In this embodiment, the two sides of the pedal fixing seat 1 are provided with tracks, and the telescopic step frame 4 completes telescopic motion in the guide rails.

In this embodiment, the two sides of the telescopic step frame 4 are provided with sliding blocks 5, the sliding blocks 5 are arranged in the tracks, and the sliding blocks 5 play a role in supporting and sliding guiding.

In the present embodiment, the electric pull rod 2 is a driving unit capable of providing power for the telescopic movement of such a telescopic pedal structure.

In order to facilitate further understanding of the above technical solutions, the working principle thereof will now be explained:

when the door is opened, the sensor on the telescopic pedal transmits a signal to the control system, the control system gives an instruction to the controller, and the controller controls the driving unit to drive the driving rod to rotate clockwise, so that the connecting rod drives the electric pull rod 2 to follow up, and under the traction of the electric pull rod 2, the telescopic pedal frame 4 slides in the track of the pedal fixing seat 1, so that the pedal reaches the set position. When the door is closed, the signal is transmitted to the controller again, and the controller controls the driving unit to rotate reversely, so that the electric pull rod 2 retracts, and the telescopic step frame 4 slides reversely in the track of the pedal fixing seat 1, thereby completing the retraction state of the telescopic pedal.

By adopting the novel telescopic pedal structure, the action control is convenient, the linkage control with the rolling door can be realized, and the withdrawing state after the installation is integrally beautiful.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
