Technical Field
[0001] The utility model relates to the technical field of seats, and more specifically to an electric seat adjustment device. Background Art
[0002] At present, the seat back angle adjustment device generally adjusts the angle between the base and the seat back through an angle adjustment handle. However, the angle adjustment handle is generally hidden on the inside of the seat back, rather than being set in a conspicuous position that is easy for users to identify, and has poor indication. At the same time, when the angle is adjusted, the parts of the mechanism often directly rub against each other, which will produce a sense of blockage or a friction sound. After long-term use, the surface coating of the metal parts is easily worn, reducing the service life of the equipment.
[0003] In response to the above problems, regarding the poor indication of the position of the adjustment handle, and the direct dry friction between the parts of the existing mechanism when adjusting the angle, the surface coating of the metal parts is easy to wear, which reduces the service life of the equipment. After a lot of searches, a Chinese utility model with application number CN205239208U was found, which provides a child safety seat back angle adjustment device. The utility model includes a base, a slide rail frame, an adjustment handle, a positioning pin and a slide rail. The slide rail frame is arranged on the base and is arranged along the front and rear direction of the child safety seat when in use. The slide rail is connected to the bottom of the child safety seat back, and the slide rail is movably arranged on the slide rail frame and slides along the slide rail frame; the adjustment handle is connected to the slide rail, and the base is provided with a plurality of The utility model has the following problems: when sitting on the seat, the backrest angle cannot be directly adjusted. First, you need to leave the seat, disengage the locating pin from the gear hole, and then slide the base to the appropriate position to adjust the backrest angle. However, this method of adjusting the angle after leaving the seat cannot be adjusted to the appropriate position at one time, and multiple adjustments are required, resulting in inconvenient, complicated and laborious adjustment. In addition, the device uses the gear hole to cooperate with the locating pin, resulting in a limited adjustable angle of the backrest, which cannot be better adapted to more usage scenarios.
