Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to an electric bicycle with a foldable frame structure. Background Art

[0002] A folding electric bicycle is an ultra-light electric vehicle with the advantages of small size, foldability, exquisite design, excellent materials and sophisticated manufacturing technology. It is made of special light materials such as magnesium alloy, and is extremely light. It can be folded quickly through a hinged folding structure, and the folded vehicle is more compact and easy to carry and store.

[0003] In order to save space and reduce the burden of the vehicle when folding and storing, existing folding electric bicycles omit space-occupying components such as storage baskets and windshields. This results in the folding electric bicycles having a single function and being unable to meet different usage scenarios. Utility Model Content

[0004] In order to make up for the above shortcomings, the present invention provides an electric bicycle with a foldable frame structure, which aims to improve the problem that foldable electric bicycles have a single function due to space saving and cannot meet different usage scenarios.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an electric bicycle with a foldable frame structure, comprising a back panel, a screw being threadedly connected to the right side of the back panel, a movable bar being slidably connected to the right side of the back panel, the movable bar being rotatably connected to the screw, two limiting columns being fixedly connected to the lower front side of the back panel, a sliding plate being slidably connected to the front side of the back panel, a connecting block being fixedly connected to the front side of the sliding plate, a fixing rod being fixedly connected to the left side of the movable bar, a control rod being fixedly connected to the rear side of the back panel, a frame being fixedly connected to the lower side of the control rod, a locking assembly being provided on the right side of the frame, and the locking assembly being used to prevent the electric bicycle from accidentally unfolding after being folded.

[0006] Preferably, the locking assembly includes a fixed plate, which is located on the right side of the frame. Three connecting columns are fixedly connected to the right side of the fixed plate. A rotating ring is fixedly connected to the right side of the three connecting columns. Three control columns are rotatably connected to the inner wall of the rotating ring. The rotating plate is fixedly connected to the left side of the three control columns.

[0007] Preferably, grooves are provided on the surfaces of the back plate and the moving bar, and the grooves are triangular grooves.

[0008] Preferably, a lock column is fixedly connected to the right side of the frame.

[0009] Preferably, the three rotating disks are all rotatably connected with fixed columns.

[0010] Preferably, the vehicle frame is fixedly connected to the three fixing columns.

[0011] Preferably, the locking column is a T-shaped column, and when the electric bicycle is folded, the locking column is located just on the left side of the rotating ring.

[0012] Preferably, the distance between the right side of the rotating disk and the left side of the fixed disk is the same as the thickness of the protruding disc at the left end of the lock column.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the present invention, rotating the screw drives the moving bar to move to the left, and the moving bar drives the fixed rod to move to the left. At this time, the connecting block connecting different modules slides into the groove through the sliding plate. When the sliding plate moves to the position of the limit column, the screw is rotated in the opposite direction, and the screw drives the moving bar to move to the right. The moving bar drives the control to move to the right until the moving plate is completely stuck, thereby realizing the replacement of different accessory modules to meet different usage scenarios.

[0015] 2. In the present invention, the rotating ring is rotated to make the rotating disk rotate under the control of the fixed column and the second control column to create a space for the lock column to be inserted. After the lock column is inserted, the rotating ring is rotated in the opposite direction. At this time, the rotating disk rotates under the control of the fixed column and the second control column to clamp the lock column, thereby preventing the electric bicycle from accidentally unfolding after being folded.

The control rod 2 is used to fix the position of the back plate 9. The frame 16 is used to control the position of the control rod 2, so as to realize the replacement of different accessory modules to meet different usage scenarios.

[0026] Reference Figure 5 The locking assembly includes a fixed plate 3, which is located on the right side of the frame 16. Three connecting columns 14 are fixedly connected to the right side of the fixed plate 3. The three connecting columns 14 are fixedly connected to the right side of the rotating ring 11. The inner wall of the rotating ring 11 is rotatably connected to three control columns 15. The left side of the three control columns 15 is fixedly connected to the rotating plate 12.
