Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts and specifically relates to a dual-motor turntable device for automobile seats. Background Art

[0002] At present, with the continuous improvement of the intelligence level of the automobile industry and the rapid development of unmanned driving technology, the rotating seats that originally only existed in some large luxury commercial vehicles have become an increasingly important focus of current intelligent automobile research and development; as a rotating seat that can change the sitting orientation of the occupants and enrich the occupants' various sitting postures in the car, the rotating seat can, on the one hand, facilitate the welcoming of guests and the communication with the passengers in the back row, and on the other hand, it can also realize the functions of rest, sleep, and easy entry. The application demand of this kind of car seat with a rotating mechanism in today's luxury cars or commercial vehicles is getting higher and higher, and it is becoming more and more popular among people. Swivel seats are generally divided into manual and electric swivel seats; manual swivel seats are quicker to adjust in rotation, but require the occupant to manually unlock the handle and rotate it by itself, which is more laborious. At the same time, the swivel mechanism of the manual swivel seat generally rotates in the form of a swivel shaft, which has a short service life and is unreliable after a person sits on it and bears weight. The swivel shaft is easily offset and damaged when it rotates. The electric swivel seat is driven by a motor for rotation adjustment, which is convenient and quick. It has become the mainstream in the current wave of vehicle intelligence. The rotation of the electric swivel seat is mostly achieved through a turntable mechanism and a motor assembly. The turntable mechanism includes a fixed plate and a moving plate that are installed together in cooperation with each other. The fixed plate is fixedly connected to the car seat track or support, and the moving plate is rotatably installed on the fixed plate, and the moving plate is fixedly connected to the car seat frame. The moving plate is driven by the motor assembly to achieve convenient rotation of the car seat.

[0003] There is no lack of technical information on the electric rotating mechanism of automobile seats in Chinese patent documents, such as: CN215204542U (electric rotating plate), CN113276734A (an electric seat rotating mechanism and automobile seat), CN213619472U (an electric rotating plate mechanism for automobile seats) and CN110626231A (an electric seat rotating mechanism), etc. The above technical documents have various advantages recorded therein, but still have the same disadvantages: first, the seats suitable for the rotating mechanisms in the current market are small and light, and the strength and durability of the rotating mechanisms cannot meet the requirements of modified seats; in addition, on the existing automobile seats with rotating mechanisms, there are more or less gaps inside the rotating mechanisms, which leads to more or less gaps in the rotation direction of the seats, and the gaps are magnified by the force arm to cause the seat to shake, which not only greatly affects the comfort of the passengers, but also increases the safety hazards; at the same time, most of the existing rotating mechanisms also have the problems of small transmission torque and unstable operation.

[0004] In view of the above situation, it is necessary to reasonably improve the electric rotating device of the existing vehicle seat.
