Description

Technical Field

[0001] The utility model relates to the technical field of hub motors, and particularly relates to a steering angle acquisition mechanism for electronic differential adjustment of double hub motors. Background Art

[0002] An electric tricycle is a three-wheel transport vehicle powered by a battery and driven by a motor for hauling goods or people. The electric tricycle adopts a tubular large-capacity, left and right liners, deep-discharge, traction-type battery, which can meet the requirements of continuous discharge for long-time work. The battery can be normally used for two years without reducing its internal capacity.

[0003] The driving modes of electric tricycles in the prior art are divided into two types. One is that a common motor directly drives the rear wheels, and the other is driven by double hub motors. However, when the vehicle turns, the rear double hub motors need differential adjustment. The prior art lacks a steering angle acquisition mechanism for the wheels, resulting in the inability of the double hub motors in the prior art to perform differential adjustment, which has certain potential safety hazards.

[0004] Therefore, how to provide a steering angle acquisition mechanism for electronic differential adjustment of double hub motors to solve the problems existing in the prior art is of great significance for its application. Summary of the Utility Model

[0005] In view of this, the purpose of this application is to provide a steering angle acquisition mechanism for electronic differential adjustment of double hub motors to solve the problem that the prior art lacks a steering angle acquisition mechanism for the wheels, resulting in the inability of the double hub motors in the prior art to perform differential adjustment, which has certain potential safety hazards.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A steering angle acquisition mechanism for electronic differential adjustment of double hub motors includes a connecting seat, an angle encoder, a driven gear, a handlebar main shaft, and a driving gear;

[0008] The angle encoder is installed at the top of the connecting seat, the driven gear is installed on the input shaft of the angle encoder, the driving gear is fixedly connected to the handlebar main shaft, and the driving gear is in transmission connection with the driven gear.

[0009] Preferably, the rotation axis of the driven gear is parallel to the rotation axis of the handlebar main shaft, and the rotation center of the driving gear is the same as the rotation center of the handlebar main shaft.

[0010] Preferably, the driving gear is semi-circular, and the maximum rotation angle of the handlebar main shaft is 180 degrees.

[0011] Preferably, the connecting seat is installed at the top of the vehicle frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model collects the steering angle of the vehicle by setting an angle encoder, a driven gear and a driving gear. When the vehicle turns, the vehicle handlebar drives the driving gear to rotate a certain angle through the main shaft. At the same time, the driving gear drives the driven gear to rotate, and the driven gear drives the input end of the angle encoder to rotate, so as to collect the rotation angle of the wheel. The angle encoder is connected to the vehicle controller, so as to adjust the differential speed of the two rear hub drive motors at different turning angles, making the riding safer.

[0024] Please refer to Figure 1-2 , this invention provides a technical solution for a steering angle acquisition mechanism for dual hub motor electronic differential adjustment: including a connecting seat 1, an angle encoder 2, a driven gear 3, a handlebar spindle 4, and a driving gear 5;

[0025] The angle encoder 2 is installed at the top of the connecting seat 1. The driven gear 3 is installed on the input shaft of the angle encoder 2. The driving gear 5 is fixedly connected to the handlebar spindle 4. The driving gear 5 is in transmission connection with the driven gear 3. The model of the angle encoder 2 is E30S4-1000-3-V-24.

[0026] The rotation axis of the driven gear 3 is parallel to the rotation axis of the handlebar spindle 4. The rotation center of the driving gear 5 is the same as the rotation center of the handlebar spindle 4.

[0027] The driving gear 5 is semi-circular, and the maximum rotation angle of the faucet main shaft 4 is 180 degrees, avoiding the turning amplitude of the wheel being greater than the maximum detection angle of the acquisition mechanism, resulting in the disengagement of the driving gear 5 and the driven gear 3.

[0028] The connecting seat 1 is installed at the top of the vehicle frame.

[0029] During specific use, when the vehicle turns, the vehicle faucet drives the driving gear 5 to rotate a certain angle through the main shaft 4.
