Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, specifically to an electrically adjustable automotive seat with height and tilt angle. Background Technology

[0002] Traditional car seat adjustment methods have many limitations. Manual adjustment requires passengers to use their body strength to operate levers or knobs, which is not only laborious but also has limited adjustment precision, making it difficult to accurately find a comfortable sitting position. Although early electric seats achieved partial electrification of functions, the adjustment dimensions were limited, mostly only able to move forward and backward or adjust the backrest angle, and could not simultaneously meet the personalized adjustment needs of seat height and tilt angle.

[0003] Some existing electric seats have problems such as jamming and excessive noise during adjustment. Some seat adjusters are prone to gear meshing problems and excessive friction between parts during transmission due to unreasonable structural design, resulting in uneven adjustment and obvious jamming, which affects the user experience. At the same time, the noise generated by the motor is not effectively controlled, which is particularly noticeable in quiet environments, reducing driving and riding comfort.

[0004] In addition, the existing seat adjustment mechanism has a complex structure and a large number of parts, which not only increases manufacturing costs but also reduces the reliability and maintainability of the seat. The complex structure makes troubleshooting and repair difficult. If a component malfunctions, it may be necessary to disassemble multiple related components for repair, which increases repair time and costs. Summary of the Invention

A second tooth 15 that meshes with the toothed plates 14 is fixedly connected to the bottom of the backrest 2.

[0018] Specifically, both the first motor 7 and the second motor 11 are three-phase asynchronous motors, capable of forward and reverse rotation. A three-phase asynchronous motor is a type of motor powered by simultaneously connected to a 380V three-phase AC current. It mainly consists of a stator and a rotor. The stator is the stationary part, while the rotor is the rotating part. There is a certain air gap between the stator and rotor. Its working principle is based on the interaction between the rotating magnetic field of the stator and the rotor current. Three-phase asynchronous motors are the leading product among small and medium-sized motors. As one of the most important power devices, they convert electrical energy into mechanical energy to drive various mechanical equipment. They have advantages such as simple structure, reliable operation, and low price, and are widely used in industries such as chemical, textile, metallurgy, construction, agricultural machinery, mining, and light industry. They are widely used as the power source for major mechanical drives such as fans, pumps, compressors, machine tools, printing presses, papermaking machines, textile machines, rolling mills, air conditioners, urban subways, light rail transit, and mining electric vehicles.

[0019] Specifically, it can precisely adjust the seat tilt angle according to the height, body type and driving habits of different drivers and passengers, providing more body-fitting support, effectively reducing fatigue during long-term driving or riding, and improving driving and riding comfort.

[0020] In this invention, a housing 16 is fixedly connected between the two sides of the inner wall of the backrest 2, and a stop block 17 is movably connected to both sides of the back of the housing 16, with the stop block 17 being engaged between the two first teeth 10.

[0021] In this invention, a fixing block 18 is fixedly connected to one side of the stop block 17 extending into the interior of the outer shell 16, and a first spring 19 is fixedly connected between the front side of the fixing block 18 and the side of the inner wall of the outer shell 16 facing each other.

[0022] In this invention, a vertical plate 20 is fixedly connected to the bottom of the inner wall of the cushion 1, and the end of the threaded rod 12 away from the second motor 11 is rotatably connected to the surface of the vertical plate 20.

[0023] In this invention, slide rails 21 are fixedly connected to both sides of the inner wall of the cushion 1, and sliders 22 are fixedly connected to the opposite sides of the two toothed plates 14. The interior of the sliders 22 is slidably connected to the surface of the slide rails 21.

A positioning block 28 is rotatably connected to the bottom of the fixed shell 3.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] In use, the first motor 7 is started by an external switch. The first motor 7 drives the fixed rod 8 to rotate, which in turn drives the gear 9 to rotate. The rotation of the gear 9 causes the first tooth 10 on the frame 5 to move, and the frame 5 causes the headrest 4 to adjust its height. The stop block 17 on the outer shell 16 is locked in the middle of the first tooth 10, which can limit the frame 5. When adjusting the tilt angle of the backrest 2, the second motor 11 is started by an external switch. The second motor 11 drives the threaded rod 12 to rotate, which in turn drives the horizontal plate 13 to move. The horizontal plate 13 drives the toothed plate 14 to move, and the movement of the toothed plate 14 causes the second tooth 15 at the bottom of the backrest 2 to rotate, thereby adjusting the angle of the backrest 2. The movable rod 24 inside the fixed shell 3 drives the movable block 25 to slide on the track 23, providing a certain amount of cushioning support for the backrest 2.
