Description

Technical Field

[0001] The utility model belongs to the technical field of transportation tools, and in particular relates to an electric bicycle. Background Art

[0002] There are many kinds of existing means of transportation, such as bicycles, electric bicycles, scooters, karts, balance bikes, electric wheelchairs, etc. Relatively speaking, two-wheeled electric balance bikes are a relatively new means of transportation. Two-wheeled electric balance bikes usually have left and right wheels side by side, and left and right pedals are located between the two wheels. The left and right feet of the human body stand on the left and right pedals, and the left and right feet change the front and back tilt angles of the left and right pedals. The control component detects the front and back tilt angles of the left and right pedals to realize forward, backward, turning and other operations.

[0003] Although technicians have modified the two-wheeled electric balance scooter to obtain some relatively unique means of transportation, these modifications have made very few changes to the two-wheeled electric balance scooter, and have hardly changed the way the pedals are between the left and right wheels. Therefore, making major changes to the two-wheeled electric balance scooter and adding a new structure can obtain a relatively novel shape and provide users with more choices. Utility Model Content

[0004] Aiming at the shortcoming that the existing means of transport have a relatively simple shape, the utility model provides an electric riding vehicle, which has a shape different from the existing ones.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: an electric riding vehicle, comprising:

[0006] Left and right wheels, both including front motors;

[0007] The left and right pedals are installed on the outside of the left and right wheels and swing back and forth;

[0008] Left and right sensors, installed on the left and right pedals, detect the front and rear tilt angles of the left and right pedal assemblies;

[0009] A controller, which receives the sensor signal and controls the front motor;

[0010] The left and right supporting frames are located between the left and right wheels and are fixedly connected to the left and right wheels respectively;

[0011] The rear frame is located between the left and right supporting frames;

[0017] The electric bicycle of the utility model includes left and right wheels, left and right supporting frames, a rear frame, an upper frame, a seat, handrails, etc., forming a unique shape with two front wheels and one rear wheel, and the rear wheel is located between the two front wheels in the left and right directions; including left and right pedals, left and right sensors, a controller, a battery, etc. When riding, sitting on the seat, holding the handrails, stepping on the left and right pedals, and controlling the electric bicycle by swinging the left and right pedals back and forth. The specific control principle is similar to that of a two-wheeled electric balance car: when the left and right pedals are both forward / backward and the difference in the forward / backward tilt angles of the left and right pedals is within a certain range, the electric bicycle goes straight forward / backward; when the difference in the forward / backward tilt angles of the left and right pedals is greater than a certain range, turning is achieved; the upper frame and the rear frame can be folded relative to the left and right supporting frames to reduce the volume of the electric bicycle.

[0018] As an improvement, the upper frame and the left and right supporting frames are rotatably connected and have a locking structure; the rear frame and the left and right supporting frames are rotatably connected and have a locking structure.

[0019] As an improvement, the upper frame and the left and right supporting frames are connected by rotation through the cooperation of the shaft and the hole; the rear frame and the left and right supporting frames are connected by rotation through the cooperation of the shaft and the hole.

[0020] As an improvement, the locking structure includes a gear assembly and a self-locking motor that drives the gear assembly. The gear assembly includes a driving gear, a driven gear and a gear shaft. The left and right supporting frames are provided with shaft holes, and the gear shaft cooperates with the shaft holes.

[0021] As an improvement, the driven gear shaft and the left and right supporting frames form an anti-slip structure in the left and right directions.

[0022] As an improvement, the vehicle seat can be folded forward relative to the upper frame and unfolded backward.

[0023] As an improvement, the vehicle seat is rotatably connected to the upper frame via a rotating shaft; the upper frame forms a rear limiting portion.

[0024] As an improvement, a left-right folding structure is formed between the pedals and the wheels.

[0025] As an improvement, the left and right support frames are arc-shaped with their centers located at the upper left; the rear frame is arc-shaped with its center located at the upper rear; and the upper frame is arc-shaped with its center located at the lower part.

[0026] As an improvement, the rear wheels include a rear motor, and the controller controls the rear motor to coordinate with the front motor based on the sensor signal.

[0027] As an improvement, a battery is installed in the upper frame; a searchlight is installed on the upper frame; and a display screen is installed on the upper frame.

[0028] The beneficial effects of the electric bicycle of the utility model are: forming a unique shape with two front wheels and one rear wheel, with the rear wheel located between the two front wheels in the left and right directions; including left and right pedals, left and right sensors, a controller, a battery, etc. When riding, sitting on the seat, holding the armrests, stepping on the left and right pedals, and controlling the electric bicycle by swinging the left and right pedals back and forth. The specific control principle is similar to that of a two-wheeled electric balance vehicle: when the left and right pedals are both forward / backward and the difference in the forward / backward tilt angles of the left and right pedals is within a certain range, the electric bicycle goes straight forward / backward; when the difference in the forward / backward tilt angles of the left and right pedals is greater than a certain range, turning is achieved; the upper frame and the rear frame can be folded relative to the left and right support frames to reduce the volume of the electric bicycle.
