Abstract

An electric rotation device for an automobile seat disclosed in the present invention includes a rotary support, a rotary disc, a fixed disc, a platen, an upper ball assembly, a lower ball assembly, a driving motor assembly, and a semicircular rack. A center of the semicircular rack coincides with a center of rotation of the rotary support. The semicircular rack is meshed with the driving gear. The driving gear in the driving motor assembly is configured to drive, by using the semicircular rack, the rotary support to perform reciprocating rotation in a range of 0-180°. A special-shaped tooth configured to prevent the driving gear from rotating out of the semicircular rack is disposed at each of extreme positions on two ends of teeth in the semicircular rack, so that the driving gear is gradually snapped with the special-shaped teeth to stop further rotation when rotating to the extreme positions on the two ends of the semicircular rack. The present invention has advantages such as an increased strength, reduced costs, and elimination of a gap between extreme positions. In addition, a wire harness of a seat is prevented from being broken as a result of unlimited rotation.

Abstract

The present invention discloses a seat rotation locking mechanism, including a locking mechanism mounted on a rotating disc in a seat rotation mechanism and at least one lockhole disposed on an outer circumference of a fixed disc in the seat rotation mechanism, where the locking mechanism includes: a lock support fixed on the rotating disc; and at least two lock pins horizontally and moveably configured in the lock support, where a first end of the lock pin is of a truncated-cone-shaped structure; and the first end of the lock pin is inserted into the lockhole, to implement zero-clearance locking by using wedging between the truncated-cone-shaped structure of the first end of the lock pin and the lockhole. The present invention eliminates a fit clearance existing after a rotation mechanism is locked, improves a grade of a product, and improves user experience. In an adjustment process, even if an operator releases an adjustment lever, a locking piece and a fixed disc do not generate scraping noise, and service life of the product is prolonged since wearing is eliminated.

Abstract

A turnover mechanism is disclosed. The turnover mechanism includes a bracket assembly, a rotatable cam, a cam resetting component, a locking pawl piece, a rotating shaft, and a rotating shaft resetting torsion spring. The cam is axially disposed on the bracket assembly. The cam resetting component is connected to the cam and the bracket assembly. The locking pawl piece is axially disposed on the bracket assembly. The cam drives the locking pawl piece to move between a locked state and an unlocked state through forward and reverse movements. The rotating shaft is axially disposed on the bracket assembly and is provided with a locking tooth plate. When the locking pawl piece is in the locked state, a locking pawl in the locking pawl piece and a locking groove on the locking tooth plate are locked and engaged, and the rotating shaft and the bracket assembly are restricted from relative rotation by the locking tooth plate. When the locking pawl piece is at an unlocked position, the locking pawl in the locking pawl piece and the locking groove on the locking tooth plate are unlocked and disengaged, and the rotating shaft and the bracket assembly are rotatable relatively. The rotating shaft resetting torsion spring is connected to the locking tooth plate and the bracket assembly. The rotating shaft resetting torsion spring drives the locking tooth plate and the rotating shaft to rotate relative to the bracket assembly.

Abstract

A cup holder with an adjustable depth includes: a cup-holder base, having at least one accommodation hole; a fixed cup holder, fixed in the accommodation hole of the cup-holder base; and a moveable cup holder, moveably sleeved over the fixed cup holder and capable of rotating around the fixed cup holder to ascend and descend, where during ascending and descending of the moveable cup holder, an inner cavity of the moveable cup holder and an inner cavity of the fixed cup holder jointly define a container placement hole for placement of containers of different heights. The present invention solves the problem that containers of different heights placed in the cup holder easily fall out when the automobile is accelerating, hard braking or travelling over uneven road surfaces. In addition, after the moveable cup holder descends to the lowest position, the moveable cup holder can completely overlap the fixed cup holder, so that the entire cup holder has a small height and is therefore suitable for installation in a thin interior trim part of the automobile, for example, in the armrest at the rear seat, thereby saving interior trim space in the automobile.
