Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

As shown in fig. 1 to 3, the self-returning electronic steering wheel of the present embodiment includes a base 1, the automatic return device comprises a return rotating wheel 4 and a return matching surface 5 arranged on the base 1, the return matching surface 5 comprises a lowest point and two sections of matching sections 51 extending from the lowest point to two sides around the rotating shaft 21 respectively, the distance between the matching sections 51 along the extending direction of the matching sections 51 and the base 1 in the axial direction of the rotating shaft 21 is gradually increased, the return rotating wheel 4 is movably arranged on the rotating shaft 21 and can move along the return matching surface 5 along the rotation of the rotating shaft 21, and an elastic part 6 forcing the return rotating wheel 4 to be attached to the return matching surface 5 is further arranged on the rotating shaft 21. This self return's electronic steering wheel is when using, the in-process that turns to with control to the steering wheel 2 rotates, return runner 4 rotates along with pivot 21 is synchronous, and keep laminating with return fitting surface 5 under the elastic compression effect of elastomeric element 6, because elastomeric element 6's hindrance effect, make the controllability and the stationarity of steering operation better, after accomplishing to turn to and unclamping steering wheel 2, under elastomeric element 6's elastic compression effect, return runner 4 can follow return fitting surface 5 and move to the minimum, thereby take pivot 21 autogyration to reset, realize ordering about steering wheel 2 self return. The electronic steering wheel realizes automatic return only through the automatic return device consisting of the return rotating wheel 4, the return matching surface 5 and the elastic part 6, does not need to be provided with a power part, and has the advantages of simple structure, low cost, easy manufacture and assembly and good working stability.

In this embodiment, the return rotating wheel 4 is installed on the rotating shaft 21 in a swinging manner through a swinging mechanism, the swinging mechanism includes a swinging arm 7 installed on the rotating shaft 21 in a hinged manner, and the return rotating wheel 4 is installed on the swinging arm 7. The return rotating wheel 4 is arranged on the rotating shaft 21 in a swinging mode through the swing arm 7 so as to be always attached to the return matching surface 5, and the device is simple and compact in structure, good in installation stability and easy to manufacture, assemble and maintain.

In this embodiment, seted up the recess on the pivot 21, swing arm 7 inserts and locates in the recess and articulated through articulated shaft and pivot 21, can further improve the installation steadiness, and do benefit to and save space.

In this embodiment, the elastic component 6 is a flexible pressure spring, the rotating shaft 21 is provided with the blocking component 8, the flexible pressure spring is sleeved on the rotating shaft 21, and two ends of the flexible pressure spring respectively and correspondingly abut against the blocking component 8 and the swing arm 7, so as to force the swing arm 7 to swing in a direction in which the return rotating wheel 4 is attached to the return fitting surface 5. The telescopic compression spring has the advantages of simple structure, low cost and convenience in installation and maintenance, and the telescopic compression spring is sleeved on the rotating shaft 21, so that the installation stability is good.

In this embodiment, preferably, the blocking component 8 is an annular sleeve that is sleeved on the outer portion of the rotating shaft 21, and the annular sleeve is in threaded fit connection with the rotating shaft 21 in a manner that the connection position can be adjusted along the axial direction of the rotating shaft 21. The axial connection position of the annular sleeve on the rotating shaft 21 is adjusted, and the compression degree of the telescopic pressure spring can be adjusted, so that the requirements of controllability and stability of steering operation and the requirement of automatic return are met.

In other embodiments, the elastic component 6 may also be a tension spring, and two ends of the tension spring are correspondingly connected to the rotating shaft 21 and the swing arm 7, respectively, so as to force the swing arm 7 to swing in a direction that the return rotating wheel 4 is attached to the return matching surface 5.

In this embodiment, the extending ends of the two segments of the matching segments 51 are connected to form an annular surface with the return matching surface 5, and a blocking member 9 for blocking the return runner 4 is disposed at the connecting position of the extending ends of the two segments of the matching segments 51.
