[0002] The car steering wheel is a control center that integrates functions such as horn, airbag, and cruise control. The steering wheel skeleton includes rim, hub and spokes. The rim is the outer edge of the steering wheel and is the ring that the driver holds. The design of this part needs to take ergonomics into consideration to ensure that the driver can control the steering wheel comfortably and stably when holding it. The rim is usually covered with a coating. The hub is the central part of the steering wheel, and the spokes are the spokes that connect the rim and the hub.

[0003] The production of the steering wheel starts with its frame. Currently, when the car steering wheel frame is formed, lightweight and high-strength materials such as magnesium alloy or aluminum alloy are usually melted into liquid, and the molten material is squeezed into the interior of the forming mold by an extruder. After the alloy material is cooled and solidified, the steering wheel frame is obtained. At this time, the frame is still high in temperature, and the robotic arm transfers it to the cooling area for cooling. After it is completely cooled, the steering wheel frame is trimmed.

[0004] After that, it is necessary to make a steering wheel cover, especially the rim cover is particularly important, which directly affects the comfort of the driver holding the steering wheel after it is made. The existing steering wheel cover uses another set of independent molding molds, and the molding molds are expensive.

[0020] 3. The present invention also further designs the rotating column so that when it is necessary to adjust to the state of processing the steering wheel skeleton, a hexagonal wrench is used to insert the adjusting screw groove on the lower module and rotate it in the opposite direction, so that the ring block moves downward along the annular groove, driving a plurality of sliders X to slide downward along the slide groove B, and the adaptation groove is disengaged from the centripetal end of the rim block A. At this time, the hemispherical block is engaged with the snap-in ball groove. At this time, the rotating column has a certain rotational resistance to prevent the gear from self-rotating.

The worm ring 51 continues to rotate until the movable ring 58 enters the oblique guide groove 571 from the arc guide groove 572. At this time, the worm ring 51 rotates to cause The gap position between the arc guide groove 572 and the centripetal guide groove 205 changes, causing the connecting column 49 to slide along the eccentric direction of the centripetal guide groove 205, so that the ring block 43 moves upward along the annular groove 202, driving a number of sliders X41 to slide upward along the slide groove B203, causing the movable ring 58 to move to the eccentric end of the inclined guide groove 571, and the covering arc groove C44 and the covering arc groove A22 on the lower module 2 form a semi-injection cavity of the rim cover, and the adapting groove 42 contacts the centripetal end of the rim block A32.

The worm ring 51 continues to rotate until the movable ring 58 enters the arc guide groove 571 from the oblique guide groove 571. 72 moves until the arc rack 53 and the gear 33 are re-engaged. The rotational resistance generated by the engagement of the hemispherical block 39 and the engaging ball groove 211 ensures the stability of the re-engagement of the rack 53 and the gear 33, thereby further improving the functionality of the present invention.
