Description

Technical Field

[0001] The utility model relates to the technical field of electric pedals, in particular to an electric telescopic pedal structure. Background Art

[0002] Automobile pedals are arranged on the edges on both sides of the car door, which is convenient for drivers and passengers to get on and off the car, especially for the elderly and children. Compared with traditional fixed pedals, electric pedals are pedals that can automatically extend and retract. When in use, the pedals extend to the side of the sill; when not in use, the pedals retract under the vehicle. The electric telescopic pedals can make the overall vehicle model more beautiful and coordinated, without increasing the width of the vehicle and without reducing the passing performance of the vehicle.

[0003] Generally, the telescopic mode of electric telescopic pedals on the market is driven by a motor to drive a set of flipping brackets to flip to drive the pedals to extend and retract, and the pedals then drive another set of flipping bracket components to flip. Due to the long pedals, the synchronism of the two sets of flipping bracket components is poor and the running resistance is large during the telescopic process, resulting in the pedals being prone to distortion, large vibration and noise during the telescopic process, and even causing problems such as motor jamming, driving circuit burning out, and pedal deformation. Currently, electric telescopic pedals on the market generally use high-power motors to drive, and use high-strength gears, high-strength transmission structures, large-diameter cables, and select high-power electronic components and other peripheral accessories, resulting in problems such as high cost, high power consumption of mechanism operation, large noise, easy jamming, and high failure rate.

[0004] Therefore, it is necessary to design an electric telescopic pedal structure with higher reliability, stable operation and low noise. Content of the Utility Model

[0005] In order to solve the above problems, a telescopic conduit structure provided by the utility model can effectively suppress the noise generated when the spring acts, and at the same time has a simple structure, low cost and wide applicability.

[0008] Optionally, in an embodiment of the utility model, the motor drive assembly is disposed between or on one side of the flipping bracket assemblies.

[0009] Optionally, in an embodiment of the utility model, the transmission assembly includes a universal joint and a transmission shaft, and the transmission shaft is connected to the motor drive assembly and the flipping bracket assembly through the universal joint.

[0010] Optionally, in an embodiment of the present utility model, output shafts are respectively provided at both ends of the motor drive assembly.

The connecting head is connected to the flipping bracket assembly, and the shaft sleeve is connected to the transmission shaft.

[0013] Optionally, in an embodiment of the present utility model, the flipping bracket assembly includes a fixed block, a connecting block, a mounting block and a torsion spring.
