Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, invention is described further.
Please refer to shown in Fig. 1, a kind of children car seat 10 provided by the invention, comprise sitting part 1, be arranged on sitting part 1 leans against 2 and head rest 3, head rest 3 is slidably connected at by headrest height adjusting mechanism and leans against on 2, to realize the height adjustment of head rest 3, the baby child making children car seat 10 can be applicable to different building shape height uses.Wherein, as shown in Fig. 2 ~ 7, headrest height adjusting mechanism of the present invention, it is be installed on for adjusting head rest 3 height on seat back 2, and Fig. 2 is the headrest height adjusting mechanism structural representation being coated with decorative cover 5.After covering decorative cover 5, the present invention is succinctly attractive in appearance.Particularly, as shown in Figure 3, headrest height adjusting mechanism comprise lean against 2, be slidably connected the head rest 3 leaned against on 2, head rest 3 is connected to by control apparatus 4 and leans against on 2, control apparatus 4 comprises operating parts 41, several draw-in grooves 42, can stretch into one of them kelly 43 of draw-in groove 42, and operating parts 41 is vertically slidably connected on head rest 3, and kelly 43 is laterally slidably connected on head rest 3, draw-in groove 42 is arranged on and leans against on 2, and the spacing between draw-in groove 42 adjusts the actual conditions such as interval according to head rest 3 and determines.
Operating parts 41 is provided with the limiting stopper 411 (shown in Fig. 5 or Fig. 6) for being positioned at kelly 43 one end in draw-in groove 42, when limiting stopper 411 is sticked between two kellies 43, the other end of kelly 43 stretches in draw-in groove 42 respectively, head rest 3 is locked in and leans against on 2, when limiting stopper 411 moves apart between two kellies 43, head rest 3 unlocks, now head rest 3 is free to slide in leaning against on 2, user can adjust head rest 3 as required and be positioned at and lean against on the diverse location of 2, and is stretched in draw-in groove 42 by kelly 43 and lock.Preferably, in the present embodiment, draw-in groove 42 is echelon form structure, and kelly 43 one end stretching into draw-in groove 42 is arc shape structure, kelly 43 is in course of adjustment and is easily inside contracted by the interference of the sidewall of draw-in groove 42, adjust to facilitate head rest 3.
Preferably, some draw-in grooves 42 are symmetricly set on the both sides leaning against 2, and kelly 43 has two, two kellies 43 lay respectively at the both sides of operating parts 41, by two kellies 43 respectively correspondence stretch in draw-in groove 42 and lock, stabilized structure, makes head rest 3 locate more stable, reliable.Preferably, as shown in Figure 5 and Figure 6, be connected with elastic component 44 between two kellies 43, kelly 43 is automatically reset by the elastic reaction of elastic component 44.More specifically, in the present embodiment, elastic component 44 is a Compress Spring, and the two ends of elastic component 44 connect two kellies 43 respectively.When limiting stopper 411 departs from kelly 43 spacing, kelly 43 can freely in contract compression elastic piece 44. more specifically, the fastening end 43a of kelly 43 is preferably designed to level and smooth arcuate structure, and the inwall up and down of draw-in groove 42 is preferably designed to trapezoidal inclined plane.Therefore when user moves up and down head rest 3, fastening end 43a can be interfered in the inclined-plane on draw-in groove 42 inwall, kelly 43 being moved inward and departs from draw-in groove 42, making head rest 3 can be free to slide adjustment in leaning against on 2.When fastening end 43a adjusts to different draw-in grooves 42, kelly 43 can reset in another draw-in groove 42 under the elastic force of elastic component 44 by compression.To be adjusted complete after, limiting stopper is sticked in again between two kellies 43, kelly 43 cannot be moved inward, complete the locking of head rest 3.
Preferably, the upper end of head rest 3 offers gathering hole 31, the top of operating parts 41 is provided with handle 412, handle 412 is revealed on gathering hole 31, user is by handle 412 upwards pulling process part 41, what make the limiting stopper 411 on operating parts 41 depart from kelly 43 is spacing, and namely head rest 3 becomes released state relative to leaning against 2.
Preferably, the upper end of operating parts 41 is convexly equipped with projection 413, and head rest 3 is provided with the elastic portion 32 coordinated with projection 413, and what utilize elastic portion 32 and projection 413 coordinates the reset reaching operating parts 41, realizes the lock-out state of head rest 3.In the present embodiment, as shown in Figure 7, elastic portion 32 has an arc-shaped curved surface structure, namely be under the elastic reaction of elastic portion 32, order about projection 413 to move down, thus operating parts 41 is moved down, the limiting stopper 411 on operating parts 41 is sticked between kelly 43 and limits kelly 43 transverse shifting, its one end is stretched into and is fixed in draw-in groove 42.In the present embodiment, operating parts 41 is rod-like structure as shown in Figure 4, compact conformation.
The invention is not restricted to above-described embodiment, another embodiment as shown in Figure 8, operating parts 41 can utilize spring 414 to realize automatically reseting, and realizes the lock-out state of head rest 3, replaces the projection 413 of above-described embodiment and the effect of elastic portion 32.Particularly, operating parts 41 and be connected with spring 414 between leaning against 2, this spring 414 one end is connected with operating parts 41, its other end with lean against 2 and be connected.When head rest 3 leans against after 2 adjustment terminate relatively, user's release handle 412, under the elastic reaction of spring 414, operating parts 41 moves down, limiting stopper 411 on operating parts 41 is sticked between kelly 43 and limits kelly 43 transverse shifting, make kelly 43 one end stretch into and be fixed in draw-in groove 42, realize the locking of head rest 3.
Compared with prior art, head rest 3 of the present invention is connected to by control apparatus 4 and leans against on 2, control apparatus 4 comprises operating parts 41, several draw-in grooves 42, can stretch into one of them a pair kelly 43 of draw-in groove 42, operating parts 41 is vertically slidably connected on head rest 3, kelly 43 is laterally slidably connected on head rest 3, draw-in groove 42 is arranged on and leans against on 2, and operating parts 41 is provided with and is selectively arranged at this to the limiting stopper 411 between kelly 43.When limiting stopper 411 is between this is to kelly 43, this stretches into respectively the other end of kelly 43 and is fixed in corresponding draw-in groove 42, is locked in by head rest 3 and leans against on 2; When limiting stopper 411 departs from kelly 43 spacing, head rest 3 is free to slide in leaning against on 2, and user can adjust head rest 3 as required and be positioned at and lean against on the diverse location of 2, and is stretched in draw-in groove 42 by kelly 43 and lock.So realize the height adjustment of head rest 3, use with the baby of applicable different building shape height child, meet the different demands of user, structure of the present invention is simple, and its assembling is easy to operate with adjustment.
The above disclosed preferred embodiment being only invention, certainly can not limit the interest field of invention, therefore according to the equivalent variations that patent application the scope of the claims is done, still belong to the scope that invention is contained with this.
