Description
Technical field
The present invention relates to a kind of armchair structure, specifically refer to a kind of two guide groove attitude regulating mechanisms of child safety seat.
Background technology
In recent years, along with the fast development of automobile industry, automobile services industry, China's domestic automobile quantity is constantly doubled, and the traffic law of China is also constantly perfect, and when manned vehicle being loaded with child, laws and regulations requirement children must be sitting on child safety seat.Child safety seat is exactly the designed for children that one aims at different weight (or age bracket), child is strapped in safety seat, effectively can improve the seat of children riding safety.According to traffic accident data statistics, nearly more than 18000 children die from traffic accident every year, and when getting into an accident, the virgin mortality of baby of not installing child safety seat in automobile is 8 times that have installed child safety seat, and injury rate is 3 times.These data show, a child safety seat having more safety of research invention is of practical significance and is worth very much.Recent years, due to the frequent generation of traffic accident, automobile children safety chair performance requriements is improved constantly, traditional child safety seat, can not meet the product demand of national standard and people.
Traditional safety seat is a kind of common seat, locate, make children need to be subject to the constraint of seatbelt, and the attitude of seat own can not regulate by interlocking with the hook in back seat undercut.Analyze known to conventional child safety seat: the traveling comfort that the attitude of seat own cannot regulate, fixed type headrest can have a strong impact on seat, does not meet the design of hommization, is be functional defect.
The chair angle of the child safety seat also had at present can regulate, thus realizes the adjustment of seat attitude, but its structure but has improves part not to the utmost.Such as: CN200820162676.0, CN201020280358.1, CN201120269900.8, CN201210377570.3 etc. Chinese patent application, before these patents, the seat attitude of case is when regulating location, mostly realize location by the structure such as limiting stopper, position-limited lever, but position-limited lever only arranges one usually, limiting stopper is generally paired setting.This position limiting structure generally will bear the total weight of seat, insufficient strength.Also the seat had bears weight by base, position limiting structure only plays position-limiting action, but this structure, when unforeseen circumstancess such as sudden stops, seat will have the trend overturn forward, and the application force of upset will all be born by position limiting structure, position limiting structure undercapacity, to bring potential safety hazard to child seat, structure is to be improved.
Summary of the invention
Technical matters to be solved by this invention is the two guide groove attitude regulating mechanisms providing a kind of child safety seat, and it not only has seat pose adjustment function, make child safety seat become more flexible, comfortable, practical, and structure is reliably safer.
For solving the problems of the technologies described above, technical solution of the present invention is:
Two guide groove attitude regulating mechanisms for child safety seat, are located between cushion frame and base, and it comprises pivoted arm and two guide barrel construction; This pivoted arm front end and cushion frame are rotationally connected, and its rear end and stage casing are respectively equipped with the first gear portion and the second gear portion; Described pair of guide barrel construction is arranged on base, and it comprises the first guide groove being positioned at below and the second guide groove being positioned at top, and the second guide groove is from rear forward direction surface thereof; Two guide grooves are respectively equipped with some gear grooves, the some second gear grooves being namely located at the some first gear grooves on the first guide groove and being arranged on the second guide groove, and the first gear groove and the second gear groove embed for the first gear portion and the second gear portion respectively; Be connected with described base rotation on rear side of described cushion frame.
Preferably, described pivoted arm is provided with symmetrical two, and two pivoted arm front ends are connected by pivoted arm rotating shaft, this pivoted arm rotating shaft through the forward axis hole of described cushion frame lower front to realize being rotationally connected of pivoted arm and cushion frame; The rear end of two pivoted arms is connected respectively by the first gear lever and the second gear lever with stage casing, and the two ends of two gear levers pass the first gear portion described in formation and the second gear portion from the outside of two pivoted arms; This pair of guide barrel construction coordinates two pivoted arms to be also provided with symmetrical two.
Preferably, described two guide barrel constructions are arranged on a two guide groove positioning plate, and this pair of guide groove positioning plate is then arranged in the shape groove on described base.
Preferably, described base is made up of the upper cover mutually fastened up and down and lower cover, and described shape groove is arranged on the mounting groove sidewall on front side of upper cover.
Preferably, described base front portion is provided with groove according to the track of the first guide groove, and the first gear lever on described pivoted arm passes this groove and stretches out.
Preferably, described two gear levers are made up of two sections of bars respectively, are connected between two sections of bars of two gear levers respectively by head rod with the second pipe link.
Preferably, be provided with rear rotating shaft on rear side of described base, this rear rotating shaft realizes being rotationally connected of base and cushion frame through the rear shaft hole of rear side bottom described cushion frame.
Preferably, the rear side of described cushion frame is provided with two arc reinforced ribs, and base arranges the limit guide rail suitable with this arc reinforced rib.
Preferably, the rear side of described cushion frame is provided with two arc reinforced ribs, and base arranges the limit guide rail suitable with this arc reinforced rib; Described rear shaft hole is arranged on this arc reinforced rib, and the arc center of circle of this arc reinforced rib overlaps with the center of circle of rear shaft hole.
After adopting such scheme, two guide groove attitude regulating mechanisms of a kind of child safety seat of the present invention, using the turning cylinder of pivoted arm and cushion frame as one of attitude regulation fulcrum of cushion frame and base, using the turning cylinder of cushion frame and base rear end as another attitude regulation fulcrum; By the restriction changing the first gear portion on pivoted arm, the second gear portion coordinates two guide barrel construction track in adjustment, reach succinctly, effectively, attitude regulation effect swimmingly.Whole attitude regulating mechanism is simple for structure, and adjustment operation is simple and convenient, and seat is in use comfortable more flexibly, practical, meets hommization user demand.
And more crucially, the present invention not merely acts on two fulcrums to the bearing force of cushion frame, also carried on a shoulder pole by two gear parts simultaneously, therefore can improve the safety performance of seat.Meanwhile, when under the unforeseen circumstancess such as sudden stop, when seat has the propulsive effort overturn forward, rear fulcrum can prevent cushion frame from overturning forward, thus increases safety in utilization.
