Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, in particular to a steering device with an offset steering wheel for an electric tricycle. Background Art

[0002] An electrically operated tricycle is a three-wheeled vehicle powered by a battery and driven by an electric motor, used for transporting goods or people. Electric tricycles utilize large-capacity tubular, left- and right-lined, deep-discharge, traction-type batteries, capable of withstanding long periods of continuous discharge. The batteries can maintain their charge for two years of normal use.

[0003] Electric tricycles, with their versatile, maneuverable, easy-to-maintain, and affordable advantages, are ideal for navigating narrow streets. They feature a reverse switch, allowing for both forward and reverse travel, making them particularly practical in narrow alleys and lanes, making them convenient for both driving and parking. They are widely used in short-distance transportation, including for families, urban and rural areas, individual rentals, factories, mining areas, sanitation services, and community cleaning.

[0004] Most existing electric tricycles have the steering device set in the center of the front of the vehicle. This design is convenient for control, but the front row can generally only accommodate one person. If there are multiple people in the front row, it will affect the driver's control of the vehicle and affect the safety of the vehicle during driving.

[0005] Therefore, the present application provides an offset steering wheel steering device for an electric tricycle to overcome the defects of the prior art. Utility Model Content

[0006] The utility model aims to solve the problem that when multiple people are seated in the front row of the existing electric tricycle, the driver's control of the vehicle will be affected, which will affect the safety of the vehicle during driving.

[0007] The technical solution of the utility model provides a steering device with an offset steering wheel for an electric tricycle, comprising a steering wheel, the bottom of the steering wheel is transmission-connected to a steering machine, characterized in that: one end of a pull rod in the steering machine is rotatably connected to a ball head 1, the top of the ball head 1 is screwed with a reversing mechanism, one end of the reversing mechanism is screwed with a ball head 2, the bottom of the ball head 2 is hinged to a steering adjustment rod, the end of the steering adjustment rod away from the ball head 2 is hinged to a ball head 3, the bottom of the ball head 3 is screwed with a swing arm, the end of the swing arm away from the ball head 3 is fixedly connected to a connecting shaft, the bottom of the connecting shaft is connected to a front fork, two relatively arranged shock-absorbing steering shafts are fixed on the bottom of the front fork, a wheel is installed between the two shock-absorbing steering shafts, the outer sleeve of the connecting shaft is provided with a connecting arm, the connecting arm is arranged between the swing arm and the front fork, the connecting arm is rotatably connected to the connecting shaft, and a frame is fixed to one side of the connecting arm.

[0008] The reversing mechanism includes two relatively arranged connecting rods, one and two, wherein the connecting rod one is arranged below the connecting rod two, and the connecting rod three is fixed between the connecting rod one and the connecting rod two. The end of the connecting rod one away from the connecting rod three is threadedly connected to the top of the ball head one, and the end of the connecting rod two away from the connecting rod three is threadedly connected to the top of the ball head two.

[0009] The beneficial effects of the electric tricycle offset steering wheel steering device provided by the utility model are:

[0010] The utility model offsets the steering wheel by arranging a ball head 1, a reversing mechanism, a ball head 2, and a steering adjustment rod at one end of the steering machine. This structure has a small installation space and a simple structure, so that when there are multiple people sitting in the front row, the driver can still stably control the direction of the vehicle without affecting the driver's control of the vehicle, and has higher safety.
