Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a vehicle steering wheel integrated with a power steering device. Background Art

[0002] In recent years, with the popularization of power steering, turning the steering wheel has become easier and easier. As a result, drivers' demand for safe one-handed steering is also increasing.

[0003] At the same time, as competition in the automotive industry becomes increasingly fierce, many manufacturers have tried to change the round steering wheel to a D-shaped, hexagonal, U-shaped or other special-shaped steering wheel in order to cater to the driver's pursuit of practicality and personalization. These special-shaped steering wheels also have their own advantages and disadvantages. For example, the U-shaped steering wheel is deeply loved by young drivers due to its personalized and fashionable design. Moreover, the U-shaped steering wheel is convenient for the driver to enter and exit the cab, and does not block the view of the instrument screen during the vehicle's movement. These are all incomparable to the round steering wheel. The disadvantage is that when turning at a large angle, especially when the vehicle turns around, it is very inconvenient to control with both hands compared to the round steering wheel, and there is even a risk of grabbing air when turning the hand. If the steering wheel is turned with one hand, the hand will slip, which is also dangerous. It can be seen that the change in the shape of the steering wheel brings convenience to the driver, but also brings some inconvenience in use, especially the problem of inconvenient steering control is particularly prominent.

[0004] The steering power ball can well solve the problem of one-handed quick turning, but the existing steering power ball is usually assembled on the steering wheel through a buckle as an independent component, which is troublesome to install and not beautiful. Moreover, the existing steering power ball is only suitable for round steering wheels, and cannot be installed on special-shaped steering wheels. Utility Model Content

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods. Example 1

[0018] Reference Figure 1 The vehicle steering wheel with integrated power steering device described in this embodiment includes a circular steering wheel body and three power steering devices, wherein the power steering devices are respectively arranged at the left, right and upper parts of the circular steering wheel body.

[0019] Reference Figure 3 The steering assist device comprises a connection base integrally formed with a circular steering wheel body, a steering assist ball 1, and an installation assembly for assembling the steering assist ball 1 on the connection base. Among them:

[0020] The connecting base includes a base body 2, a cylindrical positioning block 3 located at the top of the base body 2, and a central axis 4 located at the top of the positioning block 3. The central axis of the positioning block 3 and the central axis of the central axis 4 are in a straight line.

[0021] The mounting assembly includes a bearing 5 mounted on the center shaft 4 by means of an interference fit connection.

[0022] Reference Figure 4 The steering assist ball 1 includes a steering assist ball body 11 and a cover body 12 buckled on the top of the steering assist ball body 11. The interior of the steering assist ball body 11 is provided with a hollow cavity 13, an axial hole 14 for the central axis 4 to pass through, a bearing cavity 15 for assembling the bearing 5, and a positioning cavity 16 for accommodating the positioning block 3 from top to bottom.
