Abstract

A steering assembly includes: a steering wheel ( 1 ), a support frame ( 2 ) and a flexible touch display screen ( 3 ). The support frame ( 2 ) is arranged at a center of the steering wheel ( 1 ) and fixedly connected to the steering wheel ( 1 ). The flexible touch display screen ( 3 ) is fixed on the support frame ( 2 ) and includes a piezoelectric device ( 31 ). The steering assembly can realize the functions displayed on the steering wheel, and the haptic feedback function and sound-emitting function, enhancing the authenticity and immersion of human-computer interaction. An automobile is further provided.

First claim

What is claimed is:

1 . A steering assembly, comprising:
a steering wheel; a support frame arranged at a center of the steering wheel and fixedly connected to the steering wheel; and a flexible touch display screen fixed on the support frame, comprising a piezoelectric device; wherein the piezoelectric device is a PZT piezoelectric film structure or a piezoelectric ceramic block structure.

2 . The steering assembly according to claim 1 , further comprising:
an airbag fixed to a central area of the support frame; wherein an orthographic projection of the piezoelectric device on the support frame does not overlap with an orthographic projection of the airbag on the support frame.

3 . The steering assembly according to claim 2 , wherein the flexible touch display screen is arranged on at least one side of the airbag along an extension direction of the support frame.

4 . The steering assembly according to claim 3 , wherein the flexible touch display screen is arranged on both sides of the airbag along the extension direction of the support frame.

5 . The steering assembly according to claim 2 , wherein the flexible touch display screen is arranged above the airbag.

6 . The steering assembly according to claim 2 , wherein the flexible touch display screen further comprises:
a flexible display module, and a flexible cover plate arranged on a light emitting side of the flexible display module, wherein the flexible cover plate is larger than the flexible display module in size, the piezoelectric device and the flexible display module are arranged on a same side of the flexible cover plate, and the piezoelectric device is arranged on the flexible cover plate outside the flexible display module.

7 . The steering assembly according to claim 6 , further comprising:
a protective layer arranged on a side of the flexible cover plate away from the flexible display module.

8 . The steering assembly according to claim 6 , wherein the flexible touch display screen further comprises:
a touch layer arranged on a side of the flexible cover plate facing the flexible display module or on a side of the flexible cover plate away from the flexible display module.

9 . The steering assembly according to claim 6 , wherein material of the flexible cover plate comprises acrylic, polyimide, polyvinyl chloride, or polycarbonate.

10 . The steering assembly according to claim 6 , wherein the flexible display module is an organic light emitting display module, a liquid crystal display module or an LED lamp bead.

11 . The steering assembly according to claim 6 , wherein there are a plurality of piezoelectric devices, and the piezoelectric devices are arranged on all four sides of the flexible display module, or the piezoelectric devices are arranged on two opposite sides of the flexible display module.

12 . The steering assembly according to claim 1 , further comprising:
an airbag fixed to a central area of the support frame, wherein the flexible touch display screen is arranged above the airbag; the flexible touch display screen further comprises:
a flexible display module, and
a flexible cover plate arranged on a light emitting side of the flexible display module,
wherein the piezoelectric device is arranged on a side of the flexible display module away from the flexible cover plate, and the piezoelectric device and the airbag are bonded by an adhesive layer.

13 . The steering assembly according to claim 12 , wherein there are a plurality of piezoelectric devices, and the plurality of piezoelectric devices are arranged in an array.

14 . An automobile, comprising the steering assembly according to claim 1 .

15 . A steering assembly, comprising:
a steering wheel; a support frame arranged at a center of the steering wheel and fixedly connected to the steering wheel; a flexible touch display screen fixed on the support frame, comprising a piezoelectric device; an airbag fixed to a central area of the support frame; wherein an orthographic projection of the piezoelectric device on the support frame does not overlap with an orthographic projection of the airbag on the support frame; wherein the flexible touch display screen further comprises: a flexible display module, and a flexible cover plate arranged on a light emitting side of the flexible display module, wherein the flexible cover plate is larger than the flexible display module in size, the piezoelectric device and the flexible display module are arranged on a same side of the flexible cover plate, and the piezoelectric device is arranged on the flexible cover plate outside the flexible display module.

16 . The steering assembly according to claim 15 , wherein the flexible touch display screen is arranged on at least one side of the airbag along an extension direction of the support frame.

17 . The steering assembly according to claim 15 , wherein the flexible touch display screen is arranged above the airbag.

18 . The steering assembly according to claim 15 , wherein there are a plurality of piezoelectric devices, and the piezoelectric devices are arranged on all four sides of the flexible display module, or the piezoelectric devices are arranged on two opposite sides of the flexible display module.

19 . A steering assembly, comprising:
