Preferably, the first telescopic rod 94-1 and the second telescopic rod 94-2 are coaxially arranged, so that the vibration of the bidirectional telescopic frame 9 during deformation can be reduced.
Referring to fig. 12, when the two pedals 1 move relatively, the first telescopic rod 94-1 and the second telescopic rod 94-2 perform adaptive symmetrical telescopic motion, which can ensure the symmetry of the two pedals 1 when approaching or departing from each other, so as to ensure the synchronous symmetry of the two pedals 1 when extending or retracting, avoid the two pedals 1 from being affected by unbalanced swinging or vibration, and ensure the supporting rigidity and stability and reliability of the two pedals 1 by the bidirectional telescopic frame 9.
Example five: a vehicle provided with a door electric pedal according to any one of the first to fourth embodiments.
When the transmission case 4 is installed, the transmission case is fixedly installed in the middle of the bottom of the chassis frame.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
