Deck-chair-type automobile seat frame driven by planetary gears

Abstract

The invention discloses a deck-chair-type automobile seat frame driven by planetary gears, and belongs to the technical field of automobile seats. The deck-chair-type automobile seat frame comprises a seat-frame adjusting chassis arranged on a platform floor, a seat frame body correspondingly arranged on the seat-frame adjusting chassis, a seat back frame connected with the back side of the seat frame body, a left handrail frame and a right handrail frame. The deck-chair-type automobile seat frame is characterized by further comprising a planetary gear ring supporting mechanism, a left rotating mechanism, a right rotating mechanism, a left planetary gear driving mechanism and a right planetary gear driving mechanism; the planetary gear ring supporting mechanism is connected with the seat-frame adjusting chassis, the left rotating mechanism and the right rotating mechanism are supported on the planetary gear ring supporting mechanism, the left planetary gear driving mechanism and the right planetary gear driving mechanism are arranged on the planetary gear ring supporting mechanism, the seat frame body is fixed between the left rotating mechanism and the right rotating mechanism, the seat back frame is connected with the left rotating mechanism and the right rotating mechanism, the left handrail frame is connected with the left rotating mechanism, and the right handrail frame is connected with the right rotating mechanism. The requirement generated when a passenger uses the deck-chair-type automobile seat frame as a deck chair is met, comfort is good, impacting caused by inertia is avoided, and the serve life is long.

Description

Technical field [0001] The invention belongs to the technical field of automobile seats, and in particular relates to a recliner-type automobile seat frame driven by planetary gears. Background technique [0002] The car seat frame in the prior art usually consists of a seat frame adjustment chassis, a seat frame (also called a seat basin, the same below), a seat back frame and a pair of armrest frames. The seat frame adjustment chassis is also called a seat frame support The assembly or seat frame slide rail assembly is used to adjust the front and rear displacement of the seat frame. When in use, it is set on the floor of the car compartment. The seat frame is set on the front and rear displacement adjustment chassis of the seat frame and is The front and rear displacement adjustment chassis of the seat frame forms a sliding pair. The seat back frame is hinged with the seat frame and connected with a car seat angle adjuster arranged on both sides of the seat frame. A pair of ar...

Problems solved by technology

[0006] Although the above-mentioned CN204354855U can meet the comfort requirements of the occupants to a certain extent when riding, objectively there are the following shortcomings: one, because the space in front of the seat on the vehicle is usually very limited, thus causing the seat to sit on the seat. The space for forward displacement on the slide rails of the seat frame adjustment chassis is restricted. If the seat is adjusted to the limit position, the legs of the occupant will not be able to move, and the occupant will be affected by taking care of one thing and losing another. Two, because a pair of car seat recliners are still needed to realize the rotational connection between the seat back and the seat seat (paragraph 0020 of the manual), on the one hand, the gap between the seat back and the seat The requirements for the rotating connection of the car seat recliner are very strict, especially the biggest defect of the car seat recliner, which is prone to chipping or jamming after frequent use, resulting in troublesome maintenance and replacement, often due to damage to the car seat recliner Replacing the entire seat at the same time causes a waste of resources and increases maintenance costs. On the other hand, because the requirement of synchronous adjustment of the seat and the seat back (that is, one adjustment and all adjustments) cannot be met, the car seat cannot be adjusted as required. Lives up to its name as a recliner
