It blocks adjusting rod and realizes adjusting positioning.Structure is complicated for the footstep mechanism of the structure, and handlebar etc. also takes up spatial volume, will affect
The folding etc. of wheelchair.
Utility model content
The technical problem to be solved by the present invention is to provide across the foot angular adjustments of one kind conveniently, and regulating mechanism is not take up
The electric wheelchair of volume.
In order to solve the above-mentioned technical problem, the utility model uses technical solution are as follows: a kind of across the electronic of foot adjustable angle
Wheelchair, including vehicle frame, wheel, across foot, controller and driving motor, described across foot includes column, and foot is arranged in column bottom
Pad, it is characterised in that: described across foot further includes the rotating part and fixed part being connected by a hinge, and the fixed part is arranged in vehicle frame
On, the rotating part is mounted on column, a position limited gear is arranged between rotating part and fixed part, in rotating part and fixation
It is respectively provided with gear grooved corresponding with position limited gear shape in portion, described across foot includes resetting-mechanism for resetting position limited gear
And the separating mechanism for releasing position limited gear from the gear grooved of wherein side, position limited gear are partially located in its natural state
In the gear grooved of rotating part, position is located in the gear grooved of fixed part.
Further, the resetting-mechanism is spring, and separating mechanism includes a cover board, is provided with protrusion, cover board on cover board
Positioned at the outside of fixed part, protrusion is protruded on the inside of fixed part and is offseted with position limited gear side, and spring is located at the another of position limited gear
Side, both ends offset with position limited gear and rotating part respectively.
Further, the raised end is in snap fit shape, card slot is provided on fixed part, protrusion protrudes into card slot, convex
End is played to match with card slot.
Further, the cross section of the teeth of the position limited gear is in triangular shape.
Further, removable connection between the fixed part and vehicle frame.
From above-mentioned technical proposal it can be seen that the utility model have the advantage that using position limited gear and gear grooved from
It closes, the angular adjustment across foot entirety may be implemented, and be not take up volume, facilitate the design of the functions such as the folding of entire wheelchair.
Detailed description of the invention
Fig. 1 is across the foot structural scheme of mechanism of wheelchair of the prior art.
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram across foot in the utility model；
Fig. 4 is the structural schematic diagram of rotating mechanism in the utility model.
Specific embodiment
Specific embodiment of the present utility model is illustrated below in conjunction with attached drawing.
As shown in Figures 2 and 3, the electric wheelchair of the utility model includes vehicle frame 10, wheel 30, across foot 20, handrail 60, control
Device 70 and driving motor (being located in vehicle frame, be not drawn into figure) processed.Backrest 50, cushion part 40 are also set up on vehicle frame.It is described across
Foot 20 includes column 2, foot pad 1 is arranged in 2 bottom of column, the angle adjusting mechanism across foot is by the rotation that is connected by a hinge
The composition such as portion 3 and fixed part 4, the fixed part are arranged on vehicle frame 10, and the end of fixed part is provided with 5 He of column plug body part
The arc-shaped connection sheet 6 in cross section is equipped with screw hole in connection sheet 6 and connection sheet is fixed on to pipe to be connected by bolt
External circumferential surface, column plug body part 5 are provided with several edges on the outer peripheral surface of column cock body for filling in tube body end to be connected
The reinforcing rib being axially distributed.The axial line of column plug body part 5 and the screw hole of connection sheet are vertically arranged, and screw hole is located in connection sheet
Heart position.
When this is mounted on wheelchair across foot, column plug body part is filled in the horizontal of wheelchair frame first, is connected
The outer peripheral surface of piece and tube body offsets, and is fixed tube body and connection sheet with along the bolt that tube body is arranged radially, thus will across foot installation
