Description

Technical Field

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

[0002] The pedals of electric bicycles are of fixed size and cannot be extended, which is quite inconvenient when large-sized goods need to be transported.

[0003] The existing patent authorization announcement number is: CN206900550U, which discloses an electric bicycle with extendable pedals, including a body, a battery box is provided in the middle of the body, a through-drawing slot is provided on the battery box, a locking circular hole is provided at each end of the draw-out slot, and a draw-out first pedal and a draw-out second pedal are provided in the draw-out slot. When the user needs a larger pedal, the first pedal and the second pedal can be respectively pulled out of the draw-out slot, and the first pedal and the second pedal can be fixed with the locking head. When the electric bicycle encounters a shoulder or a pothole, the card connector can be engaged with the card slot to form a whole board. In this way, the user can place the whole board on the shoulder or pothole to facilitate the movement of the electric bicycle;

[0004] However, the problem with the above patent is that the pedal and the top of the battery box are not located in the same plane, and there is a certain height difference, which affects the stability of the placed items. The placed items are not necessarily a whole box of large items, but may also be scattered small items. The above prior art cannot store and collect scattered small items, which affects actual use.

[0005] Therefore, we invent an extendable pedal structure for an electric bicycle. Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop an extendable pedal structure for an electric bicycle. Summary of the invention

[0006] The utility model aims to provide an extendable pedal structure for an electric bicycle.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The utility model discloses an extendable pedal structure for an electric bicycle, comprising: a vehicle body, a supporting cross plate provided in the middle of the vehicle body, a first groove provided at the top end of the supporting cross plate, pedals slidably connected to both sides of the inner wall of the first groove, first transverse grooves provided at both ends of the inner wall of the first groove, sliders fixedly connected to the inner sides of both ends of two groups of pedals, and the outer wall of the slider is slidably connected to the inner wall of the first transverse groove.

[0009] On both sides of the bottom end of the inner wall of the first groove, press grooves are provided. On both sides of the bottom end of the inner wall of the first transverse groove, first vertical grooves are provided. The inner wall of the first vertical groove is slidably connected to the outer wall of the slider. The height of the press groove is the same as the thickness of the pedal. The sliders at both ends of the pedal are snapped into the first vertical grooves, and the pedal is snapped into the press groove. Bolts are passed through the positioning holes three provided on the pedal and in the press groove to fix the two, so that the pedal and the first groove are in the same plane, expanding the area of the placement position.

[0010] Further, one slider is provided at any section of both ends of the pedal, and it is cylindrical. A placement frame is connected to the outside of the pedal by bolts. Support brackets are fixedly connected to the outer sides of both ends of the cross plate. The brackets are L-shaped. Second transverse grooves are provided on the brackets. The second transverse groove and the first transverse groove are in the same plane, and a notch is provided between them to penetrate the two.

[0011] The placement frame is fixed to the pedal by bolts, so that a placement space is formed between the inner wall of the placement frame and the outer wall of the pedal. The sliders at both ends of the pedal are moved along the first transverse groove and the notch to the second transverse groove and rotated 90 degrees outward, so that the top opening of the placement frame faces upward, thus facilitating the placement of some scattered objects.

[0012] In the above technical solution, a retractable pedal structure for an electric bicycle provided by the present utility model has the following beneficial effects:

[0013] The height of the press groove is the same as the thickness of the pedal. The sliders at both ends of the pedal are snapped into the first vertical grooves, and the pedal is snapped into the press groove. Bolts are passed through the positioning holes three provided on the pedal and in the press groove to fix the two, so that the pedal and the first groove are in the same plane, expanding the area of the placement position and making the placement more stable.

[0014] The placement frame is fixed to the pedal, and a placement space is formed between the inner wall of the placement frame and the outer wall of the pedal. The sliders at both ends of the pedal are moved along the first transverse groove and the notch to the second transverse groove and rotated 90 degrees outward, so that the top opening of the placement frame faces upward, thus facilitating the placement of some scattered objects and expanding the scope of use.
