Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Fig. 1 is a schematic structural view of a foldable steering wheel according to an embodiment of the present utility model. Referring to fig. 1, the foldable steering wheel comprises two symmetrical arc handle structures 1, a connecting rod 2 and a folding motor 3, wherein a supporting shaft 11 of the arc handle structure 1 is at least partially positioned in a hollow part of the connecting rod 2, a protruding column 12 is arranged on the supporting shaft 11, the protruding column 12 is movably clamped in an arc guide rail 21 on the connecting rod 2, the folding motor 3 drives the supporting shaft 11 to rotate and stretch in the connecting rod 2 in a working state, in the process, the protruding column 12 moves in the arc guide rail 21, and the supporting shaft 11 drives the arc handle structure 1 to fold downwards, fold or unfold upwards and stretch out.

When the user starts the intelligent driving function, the manual control steering wheel is not needed any more, so that the steering wheel can be folded and stored, and a larger movable space is provided for the driver. In this application scheme, when starting intelligent driving function, can be based on user selection or automatic control folding motor start, drive the circular arc and to the rotatory shrink of back shaft 11 of structure 1, drive two circular arcs simultaneously and to the folding shrink of structure 1. The support shaft 11 can be rotated to fold the arc handle structure 1, and the support shaft 11 can be contracted to retract the arc handle structure 1 inwards.

Wherein, connecting rod 2 integrated into one piece, two circular arc handle structures 1 are connected simultaneously at both ends. The connecting rods 2 are respectively used for clamping the arc guide rails 21 of the protruding columns 12 on the left and right arc handle structures 1, and the two arc handle structures 1 which are symmetrical left and right share the folding motor 3. That is, when the folding motor works, it can synchronously drive the left and right support shafts 11 to simultaneously shrink and rotate, so as to realize synchronous folding and shrinking of the two symmetrical circular arc handle structures 1.

In another implementation, the foldable steering wheel may further include a road-sensing pipe column 4 fixedly connected with the connecting rod 2 and a telescopic motor 5, where the telescopic motor 5 drives the road-sensing pipe column 4 to axially extend and retract in a working state. As shown in fig. 2, wherein the telescoping motor may be disposed inside the road feel string, shown in phantom in fig. 2.

In this scheme, on the basis that two circular arcs of bilateral symmetry are folding the shrink to structure 1, can further control the road sense tubular column 4 along its axial drive steering wheel and continue to keep away from the translation of driver to bring bigger activity space for the driver's cabin, further promote user's comfort. The telescopic example of the road sense pipe column is not limited by fixation, can be determined by combining with practical application scenes, and can realize long-distance contraction and expansion functions through a screw rod and a brush motor, and if the steering wheel is required to be completely hidden, the contraction distance can be set at 150-250 mm.

According to the scheme, based on the steering system, the non-intermediate shaft decoupling framework combines the road sense pipe column stretching and folding of the steering wheel, when a user needs manual driving, the steering wheel stretches out and expands, when a vehicle enters automatic driving, the steering wheel is folded and contracted, more space is provided for the user, meanwhile, the damage caused by the road sense pipe column during collision is avoided, and larger space and safety are provided for passengers in the whole vehicle high-order intelligent driving.

Wherein, manual driving is switched to automatic driving:

1. the steering actuator starts to respond to the intelligent driving request at the same time through the processing of the intelligent driving controller by the keys and converting the signals into folding signals. The road feel controller controls the steering wheel to return to the middle position, and after the folding steering wheel controller receives the instruction and returns the steering wheel, the folding motor is controlled to fold the steering wheel, and a completion state signal is sent when the folding is completed.

2. After receiving the folding completion signal, the axial electric control controller controls the telescopic motor to shrink the road sense pipe column, and the shrinkage completion sends out a completion state signal.

Automatic driving is switched to manual driving:

1. the intelligent driving controller processes the road sense pipe column through the keys and converts the road sense pipe column into an extension signal, and the axial electric control controller controls the road sense telescopic brush motor to extend the road sense pipe column after receiving the extension signal, so that the extension completion signal is sent out;

2. the folding steering wheel controller receives the extension completion status signal, controls the folding motor, realizes the unfolding of the steering wheel, and sends out the completion status signal after the unfolding is completed. And after receiving the unfolding state completion signal, the road feel controller controls the steering wheel to follow the angle of the current steering actuator.
