Description

Single electric seat carousel Technical Field The invention relates to the technical field of vehicle seats, in particular to a single electric seat turntable. Background With the transformation and upgrading of the automobile industry and the upgrading of the consumption demand, the electric seat is widely applied to modern automobiles due to the convenience and comfort of the electric seat. The electric turntable is driven by a motor to realize the rotation of the seat and realize the function of electric control of the rotation of the seat. The main current electric seat turntables on the market at present mostly adopt a double-motor structure, the principle is that two independent motors respectively bear the functions of unlocking and driving, one motor controls the locking mechanism to be opened and closed so as to fix or separate the turntables from the seat base, the other motor drives the turntables to rotate through gear transmission so as to adjust the angle of the seat, but the design scheme can have adverse effects on the space arrangement, cost, weight and other aspects of seat products, particularly the effect on the small electric vehicle is more remarkable, the precision requirement required for realizing gapless locking is high, and the cost for driving the turntables is further increased. Meanwhile, the electric turntable locking mechanism adopted in the prior art can generally only provide limited locking gears, can not cover any adjustment angle required by a user, and has obvious mechanical clearance between the locking mechanism and the turntable when the locking mechanism is not in the locking gears, so that the turntable can generate obvious shaking caused by jolt in the running process of a vehicle, riding comfort is affected, abnormal sound can be generated, potential safety hazards are increased even in the process of sudden acceleration and sudden braking, and in addition, the locking mechanism is directly arranged on a structural member of the electric turntable, so that the modularization degree is low. Accordingly, there is a need for improvements and enhancements in the art. Disclosure of Invention Aiming at the defects in the prior art, the invention aims to provide the single-motor seat turntable which adopts a single motor to realize stepless adjustment and can ensure that the turntable is locked without gaps when any rotation angle stops. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: A single-motor seat turntable comprises an upper turntable, a lower turntable, a motor component fixed on the lower turntable and a locking mechanism arranged between the upper turntable and the lower turntable, The locking mechanism comprises a fluted disc and a rotating disc, wherein a plurality of first protrusions are uniformly distributed on the surface of the fluted disc facing the rotating disc along the circumference, a plurality of second protrusions and a plurality of third protrusions are uniformly arranged on the outer circumferential surface of the rotating disc at intervals, each first protrusion is positioned in a locking cavity formed between the adjacent second protrusions and the third protrusions, and a roller and an elastic element are sequentially arranged between the first protrusions and the adjacent third protrusions. As a further scheme of the invention, the upper rotating disc and the lower rotating disc are also provided with a ball retainer and a plurality of balls, and a plurality of cavities for accommodating the balls are formed on the outer circumferential surface of the ball retainer. As a further scheme of the invention, a pressing disc is arranged above the upper rotating disc, and a plurality of elastic pieces for pressing the upper rotating disc are uniformly arranged on the surface of the pressing disc along the circumference. As a further aspect of the present invention, the pressing disc includes a first semicircular pressing disc and a second semicircular pressing disc, and the first semicircular pressing disc and the second semicircular pressing disc are symmetrically disposed. As a further aspect of the present invention, the locking mechanism further includes a receiving member having a receiving space for receiving the locking mechanism. As a further aspect of the present invention, the receiving member includes a plastic member and an end cap, and the end cap and the plastic member are fixed together by a plurality of tapping bolts. As a further aspect of the present invention, the receiving member further includes a locking plate, and the locking plate is located at a side of the locking mechanism adjacent to the end cap. As a further proposal of the invention, the rotating disc is fixed with the upper rotating disc through a plurality of screws. As a further aspect of the present invention, the receiving member is fixed to the lower rotating disc by a plurality of clinching bolts. Compared w
