[0039] At the same time, in the utility model, the driving part includes a flip motor 4, and the flip motor 4 is connected to the worm gear shaft 7 through a worm 8; with such a setting, the worm gear shaft 7 converts the longitudinal rotation into a lateral rotation through the rotation cooperation of the worm 8 and the worm gear, and the worm gear shaft 7 drives the entire steering wheel body 1 to rotate laterally and stop after reaching the set position, thereby realizing the folding function of the steering wheel.

[0046] specific:

[0047] The utility model discloses a flip steering wheel assembly. The main purpose is to design a flip steering wheel structure to achieve the function of storing and hiding the steering wheel, which can meet the needs of the car's intelligent cockpit and expand the application scenarios, such as entertainment mode: after the steering wheel is flipped, the large screen is allowed to rise to enter the game mode; meeting mode: after the steering wheel is flipped and folded, the seat is allowed to rotate.

[0048] A flip steering wheel assembly comprises a foldable steering wheel rim 11, a spoke 12, a coupling 3, a spoke frame 13, a flip motor 4, a connecting bridge plate 5, a fixing bracket 2, a worm shaft 7, a worm 8 and bearings.

[0049] The steering wheel rim 11, the spokes 12 and the coupling 3 are connected by bolts made of the spoke frame 13 material, and the coupling 3 and the worm gear shaft 7 are connected by interference fit, thereby ensuring the reliability of the connection.

[0050] After receiving the flip command, the flip motor 4 drives the worm 8 to rotate, and the rotational force is transmitted to the lateral rotation of the worm shaft 7 through the worm gear, thereby driving the rotation of the steering wheel assembly, and finally achieving the function of driving the steering wheel assembly to realize the flip angle.

[0051] In the present invention, the steering wheel rim 11, the spokes 12 and the spoke frame 13 are an integral assembly structure, and are connected together by bolts through the spoke frame 13 and the coupling 3 (to ensure the reliability of the connection).

[0052] The coupling 3 is fixed to the worm shaft 7 by interference fit to form a reliable connection.

[0053] The worm gear shaft 7 is then positioned on the fixed bracket 2 (8) through two bearing mechanisms 9 on the left and right sides, and finally fixed to the mounting base, so that the flipping action can be smoothly realized, thus forming the overall structure of the flippable steering wheel.

[0054] When the flip motor 4 receives a rotation position instruction from the user (it can be a manual hardware button, a soft button on the host large screen, or it can be linked to the program set in the whole vehicle, such as: get off or get on signal or entertainment signal, etc.), the motor can rotate the position (designed position) according to the input rotation instruction.

[0055] The worm 8 is then driven by the flip motor 4 to rotate longitudinally, and then through the rotation coordination of the worm 8 and the worm wheel, the worm wheel shaft 7 converts the longitudinal rotation into a lateral rotation, and the worm wheel shaft 7 drives the entire steering wheel assembly to rotate laterally, and stops after reaching the set position, thereby realizing the folding function of the steering wheel.

[0056] The applicable flip angle range of the utility model is: 0° (initial position of the steering wheel) / -70° (flip position of the steering wheel). Based on this, the steering wheel can be stored and hidden, which can meet the needs of the car's smart cockpit and expand the application scenarios, such as entertainment mode: after the steering wheel is flipped, the large screen is allowed to rise to enter the game mode, and meeting mode: after the steering wheel is flipped and folded, the seat is allowed to rotate.

[0057] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods.
