By the above-described cooperation, the steering wheel frame 1 can be rotated about the bracket 4, and the rotation of the steering wheel can be transmitted to the steering column 6 through the bevel gear 501.
The gear rack 11 on the lower surface of the bull gear 10 is low in the middle and high in the middle and low in the middle and high in the periphery of the transmission gear 12, the conical gear 501 is a conical gear which is narrow towards the central end and wide towards the peripheral end, and the transmission ratio can be designed according to requirements.
To sum up, when the driver rotates the framework 1, the bearing 8 fixedly connected with the framework 1 rotates along with the framework, and the support 4 rotatably connected with the bearing 8 and the mounting seat 2 fixed on the support seat 401 are fixed relative to the whole vehicle. When the framework 1 rotates freely, the large gear 10 fixedly connected with the hub 101 rotates along with the rotation, the large gear 10 rotates to drive the plurality of conical gears 501 which are uniformly distributed to rotate, and meanwhile, the transmission teeth 12 meshed with the plurality of conical gears 501 rotate synchronously to drive the steering column 6 fixedly connected with the transmission teeth 12 to rotate, so that a vehicle connected with the steering column 6 turns.
Through the structure, the framework 1 rotates to control the vehicle to turn, and the working ends of additional components such as an electronic screen and a control switch on the mounting seat 2 can be kept to face a driver in a convenient posture all the time.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the method embodiments described later, since they correspond to the system, the description is simple, and for the relevant points, reference may be made to the partial description of the system embodiments.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
