Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a sliding pair structure and its automotive seat. Background Technology

[0002] As a key component of a car's interior, the design and function of car seats have a crucial impact on the comfort, safety, and ergonomics of passengers. In the development of modern automobiles, as consumers' demands for driving and riding experiences continue to increase, the adjustment functions of car seats have become increasingly sophisticated. From initially only allowing simple fore-and-aft adjustments, they have gradually evolved to offer multi-directional electric adjustment, lumbar support adjustment, seat heating, ventilation, and massage functions. The introduction of these functions aims to meet the comfort and convenience needs of passengers of different body types, driving habits, and usage scenarios, enhancing the overall driving experience and helping to reduce fatigue during long drives or rides, thus contributing to driving safety.

[0003] However, existing car seat sliding adjustment mechanisms still have some prominent problems in practical applications. On the one hand, their structures are often quite complex, usually requiring an independent drive motor or a complex linkage system to achieve the seat's sliding adjustment function. This complex structure not only leads to a significant increase in production costs, making car seats account for a large proportion of the overall cost, but also occupies a certain amount of interior space due to the numerous components and cumbersome layout, thus limiting the optimal design of the car's interior space. This problem is particularly pronounced in some small cars, potentially compressing legroom for passengers and trunk space. Utility Model Content

[0004] The purpose of this invention is to provide a sliding pair structure and its automotive seat, aiming to solve the problem of complex structure and large space occupation of existing automotive seat sliding adjustment mechanisms.

[0005] To achieve the above objectives, in a first aspect, this utility model provides a sliding pair structure, including a base frame, a moving component, a base, a shaft, a backrest component, a transmission plate, and two driven plates;

[0006] The movable component is mounted on the base frame, the base is mounted on the movable component, the shaft is rotatably connected to the base and located on the base, the backrest component is mounted between the base and the shaft, the transmission plate is rotatably connected to the shaft and located on the shaft, and the two driven plates are rotatably connected to the transmission plate and rotatably connected to the vehicle body respectively.

[0007] The movable component includes two movable frames, a rotating handle, a push rod, and a fixed plate. The two movable frames are slidably connected to the base frame and fixedly connected to the base. The rotating handle is rotatably connected to the base and located on one side of the base. The push rod is fixedly connected to the rotating handle and passes through the base. The fixed plate is rotatably connected to the movable frame and located on the side of the movable frame closer to the push rod.

[0008] The moving component further includes a torsion spring one and a torsion spring two. The torsion spring one is installed on the side of the moving frame near the rotating handle, and the torsion spring two is installed on the side of the moving frame near the fixed plate.

[0009] The backrest assembly includes a backrest body, a mounting bracket, and a limit lock. The backrest body is rotatably connected to the base and to the shaft. The mounting bracket is fixedly connected to the backrest body and located on the backrest body.

[0010] In a second aspect, there is an automobile seat with a sliding pair structure, including the sliding pair structure described in the first aspect.

[0011] This utility model discloses a sliding pair structure. When the car seat needs to be adjusted, the moving component is unlocked, and the moving component drives the base to move forward on the base frame. The base drives the backrest component to rotate through the shaft, thereby adjusting the angle of the backrest component. At the same time, the rotation of the transmission plate drives the two driven plates to rotate, limiting the adjustment angle of the backrest component until the seat is adjusted to the preset angle. This utility model reduces the axial space occupied by 50%, adapts to the seat layout of microcars, and effectively solves the problem of complex structure and large space occupation of existing car seat sliding adjustment mechanisms.
