Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat cushion front basin adjustment structure. Background Art

[0002] When using seats, people of different body shapes have different lengths of thighs and calves, which makes their riding conditions in the car very different. The seat cushion plays a major supporting role for the human legs during use. Due to the sitting posture and thigh length of people of different body shapes, people with shorter legs will have too much support at the front end of the cushion, while people with long legs will have insufficient support.

[0003] The conventional front basin adjustment structure installs the motor on the front cross tube or side panel of the seat cushion and drives the adjustment through the motor's screw rod; however, when the front cross tube needs to be rotated or the front cross tube is not conducive to the installation of the motor, or there is insufficient space on the side panel to install the adjustment motor, a new installation scheme and adjustment structure are needed to implement it; a new front basin adjustment scheme is designed to address such problems.

[0005] To achieve the above-mentioned purpose, the utility model provides a seat cushion front basin adjustment structure, including a cushion side panel and a cushion front basin, the cushion front basin is rotatably mounted on the cushion side panel, and also includes an adjustment component; the adjustment component includes a rotating shaft, a screw bracket, an adjustment connecting rod and an electric screw, the rotating shaft is fixedly connected to the cushion front basin and is arranged on the cushion front basin, the screw bracket is fixedly connected to the cushion side panel and is arranged on the cushion side panel, the adjustment connecting rod is rotatably connected to the cushion side panel, connected to the rotating shaft, and arranged on the cushion side panel, the electric screw is connected to the screw bracket, connected to the adjustment connecting rod, and arranged on the adjustment connecting rod.

[0006] Wherein, the electric screw comprises a motor and a screw, the motor is connected to the adjusting connecting rod and is located on one side of the adjusting connecting rod; the screw is connected to the motor and to the screw support and is arranged on the motor.

[0007] Among them, the seat cushion front basin adjustment structure also includes a front transverse tube and a rear transverse tube, the front transverse tube is fixedly connected to the seat cushion side panel and arranged on the seat cushion side panel; the rear transverse tube is fixedly connected to the seat cushion side panel and arranged on the seat cushion side panel.

[0008] Among them, the rotating shaft includes an adjusting cross tube and a mounting clamp, the mounting clamp is fixedly connected to the front basin of the seat cushion and is located on one side of the front basin of the seat cushion; the adjusting cross tube is connected to the mounting clamp, and is rotationally connected to the adjusting connecting rod, and is arranged on the mounting clamp.

[0009] The utility model discloses a seat cushion front basin adjustment structure, wherein the motor drives the lead screw nut to rotate through a worm gear and a worm transmission method, and the lead screw nut drives the lead screw to move axially. (The structure and principle of the electric lead screw are prior art and will not be elaborated on here.) Since the lead screw is connected to the lead screw bracket, and the lead screw bracket is relatively fixed to the seat cushion side panel, the motor drives the adjusting connecting rod to rotate in the reverse direction, and the adjusting connecting rod drives the rotating shaft to rotate, thereby driving the front basin of the seat cushion to rotate on the seat cushion side panel, thereby realizing the adjustment of the front basin of the seat cushion. The utility model provides a new front basin adjustment scheme, which is different from the traditional motor installation method and performs reverse driving, thereby optimizing the layout space of the front end of the seat cushion, and more electrical components can be placed at the front end of the seat cushion. The front cross pipe of the seat cushion can have more layout forms or even be cancelled. BRIEF DESCRIPTION OF THE DRAWINGS
