摘要： 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.

摘要： Disclosed in the utility model is a vertical latch locking mechanism for a rotating seat, including a vertical latch locking mechanism mounted on a rotating disc in a seat rotation mechanism, at least one lockhole provided on a disc surface of a fixed disc in the seat rotation mechanism, and at least one first lock pin hole provided on the rotating disc. The lockhole is aligned with the first lock pin hole, and the vertical latch locking mechanism includes: a locking pin bracket fixed on the rotating disc; and at least two lock pins vertically and moveably configured on the locking pin bracket. A first end of the lock pin passes through the first lock pin hole and is inserted into the lockhole, to implement locking. In the utility model, a horizontal locking mechanism is changed to a vertical latch mechanism, radial sizes of the rotating disc and the fixed disc are greatly reduced, and a diameter can be reduced to less than 200 mm. In addition, the vertical latch locking mechanism for a rotating seat does not extend beyond the rotating disc and can be hidden at a lower end of a cushion. The lock pin moves in an inner cavity of the rotating disc and does not scratch the outside, providing a good appearance.

摘要： The present invention discloses a rotation device for a vehicle seat. The device includes a fixed disc, a lower ball assembly, a movable disc, an upper ball assembly, and a platen successively arranged from bottom to top. A first lower circular track is formed on the fixed disc. A first upper circular track and a second lower circular track are formed on the movable disc. A second upper circular track is formed on the platen. A diameter of a first arcuate envelope line of the first lower circular track that is in contact with a lower ball and a diameter of a second arcuate envelope line of the first upper circular track that is in contact with the lower ball are both equal to a diameter of the lower ball, and a height of the first arcuate envelope line and a height of the second arcuate envelope line are 0.8 times the diameter of the lower ball. A diameter of a third arcuate envelope line of the second lower circular track that is in contact with an upper ball and a diameter of a fourth arcuate envelope line of the second upper circular track that is in contact with the upper ball are both equal to a diameter of the upper ball, and a height of the third arcuate envelope line and a height of the fourth arcuate envelope line are both 0.8 times the diameter of the upper ball. By means of the present invention, a smooth rotary operating force can be achieved, and a service life of the rotation device can be properly prolonged.

摘要： 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.

摘要： A turnable headrest includes a headrest body and a headrest rod. The headrest body is wrapped around and hinged to a horizontal rod of the headrest rod, and two vertical rods of the headrest rod are inserted into a seat. The turnable headrest further includes a fixed tooth, a torsion spring, a rotary tooth, and a reset tension spring. A headrest body locking portion, a headrest body rotary tooth portion, and a turned headrest body locking portion are disposed on the fixed tooth. A rotary tooth portion is disposed on the rotary tooth. When the rotary tooth portion is mated with the headrest body locking portion on the fixed tooth, the headrest body is locked at an initial use position. When the rotary tooth portion is mated with the headrest body rotary tooth portion on the fixed tooth, the headrest body is at a turnable position. When the rotary tooth portion is mated with the turned headrest body locking portion on the fixed tooth, the headrest body is locked at a flat position. The turnable headrest has advantages such as a strong self-locking ability, a small quantity of parts, a simple structure, and low costs.
