Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a lightweight automobile seat frame. Background Art

[0002] The car seat frame is the main support of the seat, which bears the weight of the seat and the pressure of the human body. The type and quality of the seat frame directly affect the comfort and safety of the seat. Common car seat frame materials include steel, aluminum alloy, carbon fiber, plastic and polyamide fiber. The structure of the car seat frame is diverse. Common passenger car front frame has full tube structure, sheet tube structure and full sheet structure. In short, the car seat frame is an important part of the car seat, among which lightweight is an important function of the car seat frame.

[0003] For example, the Chinese patent "Automobile Seat Frame" with announcement number CN212098555U includes a pair of armrest frames, a backrest frame, a seat frame and a recliner assembly, the pair of armrest frames are respectively arranged on both sides of the seat frame, the lower end of the backrest frame is connected to the upper end of the recliner assembly, the lower end of the recliner is connected to the seat frame, the recliner assembly is used to adjust the backrest frame to provide a degree of freedom that allows the backrest frame to rotate around a horizontal axis above the seat frame, the armrest frame includes a fixed plate, a support assembly and a locking assembly, the support assembly is welded with a fixed plate, the support assembly is installed with a locking assembly on the side of the seat frame, the locking assembly is connected to the seat frame, the backrest frame includes a pair of side panels, a plurality of backrest cross tubes and a headrest tube, the plurality of backrest cross tubes are distributed from bottom to top between a pair of side panels and fixedly connected to a pair of side panels.

[0004] Although the above-mentioned existing technology can realize the use of automobile seat frames, in actual use, on the one hand, the automobile seat frames are not lightweight enough. When manufacturing the automobile seat frames, steel or aluminum is used for welding and assembly, which leads to an increase in the overall weight of the car, thereby increasing the vehicle's fuel consumption and affecting the vehicle's handling and power performance. On the other hand, the position adjustment of the automobile seat frame is not flexible enough. When adjusting the car seat, it is necessary to move it by turning a knob, resulting in the need to turn the knob every time the car seat frame is adjusted, thereby reducing the efficiency of the car seat frame adjustment. Therefore, it does not meet existing needs. In this regard, we have proposed a lightweight automobile seat frame. Utility Model Content

The lead screw moves on the Y-axis together with the horizontal frame through the external threaded belt moving rod. At the same time, the pulley on the moving rod slides on the slide rail until the horizontal frame moves to a suitable position. Then the drive motor is turned on to make the output shaft of the drive motor drive the vertical frame to rotate until the vertical frame moves to fit the back of the occupant, which simplifies the adjustment steps of the car seat frame and improves the efficiency of the car seat frame adjustment.

[0018] 3. The utility model can reduce the sponge filling inside the car seat frame through the first comfort spring and the second comfort spring.
