Specific embodiment
Technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
Embodiment 1
As depicted in figs. 1 and 2, children trolley of the invention includes vehicle frame 1, seat board 2, backboard 3 and cloth set 4.
Seat board 2 is arranged on vehicle frame 1, and backboard 3 and seat board 2 are rotatablely connected, which has sitting posture use state
With lying posture use state, backboard 3 is rotated before and after seat board 2 so as to make children trolley in sitting posture use state and lying posture
It is converted between state.Cloth set 4 is separately positioned on seat board 2 and backboard 3 and the left and right sides of children trolley, the left and right sides
The cloth set 4 of every side is fixed between vehicle frame 1, seat board 2 and backboard 3.
Children trolley further include backrest adjust component, backrest adjust component can limit backboard 3 position so that
Children trolley is in sitting posture use state and lying posture use state.It includes that backrest adjusts band 5 that backrest, which adjusts component, and backrest adjusts band
5 are separately positioned on the left and right sides of children trolley, and the one end that the backrest of every side adjusts band 5 is fixed at corresponding side
On vehicle frame 1, the other end that the backrest of every side adjusts band 5 each extends to the rear portion of backboard 3.It further includes using that backrest, which adjusts component,
The locking mechanism of band 5 is adjusted in locking backrest, the other end that the backrest of every side adjusts band 5 each extends to the rear portion of backboard 3
Pass through locking mechanism latched position afterwards.
Children trolley further includes the elastic component with certain elasticity, when children trolley is in lying posture use state and backboard
3 when not stressing, backboard 3 can the automatic rotation forward under the action of the elastic force of elastic component, to make children trolley from lying
Appearance use state is transformed into sitting posture use state.In the present embodiment, when children trolley is in lying posture use state, at elastic component
In the state being stretched, and when children trolley is in sitting posture use state, elastic component can automatic rebounding contraction, preferably elastic component
Can automatic rebounding be retracted to original state.
In the present embodiment, elastic component can be all or part of cloth set 4, i.e., cloth set 4 is whole flexible bullet
Property cloth, alternatively, a part of cloth set 4 be flexible elastical cloth.Specifically, the cloth set 4 of the every side in the left and right sides includes the
One cloth set 41 and the second cloth set 42, the front of the first cloth set 41 are fixed on vehicle frame 1, and the rear portion fixation of the second cloth set 42 is set
It sets on backboard 3, the rear portion of the first cloth set 41 is mutually fixedly connected with the front of the second cloth set 42, and the second cloth set 42 is elasticity
Part, i.e. the second cloth set 42 are the elastical cloth with certain elasticity.
In this way when children trolley is in lying posture use state, as shown in Figure 1, turn over after 3 stress of backboard, second
Cloth set 42 is stretched, and in the state being straightened, backrest adjusts band 5 and is partially supported upon the rear portion of backboard 3 and by locking machine
Structure locking, persistently turns over so as to limit backboard 3, so that the children trolley is stablized in lying posture use state.
When the children being located on children trolley are in sitting state or children leave children trolley, i.e., at children trolley
In light condition, at this point, the second cloth set 42 acts on meeting automatic rebounding due to natural resiliency since backboard 3 is not by external force
It shrinks, so that backboard 3 be pulled to rotate forward, until the second cloth set 42 returns to original state, backboard 3 is rotated forward at this time
To making children trolley be in sitting posture use state, as shown in Fig. 2, position and locking that backrest adjusts band 5 are then adjusted, thus just
Stablize the children trolley under sitting posture use state.In this state, entire cloth set 4 is all very smooth, corrugationless, so that
The shape of the children trolley is clean and tidy, beautiful.
Embodiment 2
As shown in Figure 3 and Figure 4, in this embodiment, cloth set 4 does not have elasticity all, and elastic component is to be separately positioned on left and right
The elastic band 6 with certain elasticity in the cloth set 4 of two sides.Specifically, the one end of elastic band 6 extends to the direction of vehicle frame 1
And be fixed on vehicle frame 1, the other end of elastic band 6 extends to the direction of backboard 3 and is fixed at backboard 3
On.The elastic band 6 of every side it is settable one or more.
Remaining is same as Example 1.
In this way when children trolley is in lying posture use state, as shown in figure 3, turn over after 3 stress of backboard, it is elastic
Band 6 is stretched, and in the state being straightened, cloth set 4 is also at the state being straightened at this time, and backrest adjusts band 5 and is supported on backrest
The rear portion of plate 3 is simultaneously locked by locking mechanism, is persistently turned over so as to limit backboard 3, so that the children trolley is stablized
In lying posture use state.
When the children being located on children trolley are in sitting state or children leave children trolley, i.e., at children trolley
In light condition, at this point, elastic band 6 is received due to the natural resiliency meeting of acting on automatic rebounding since backboard 3 is not by external force
Contracting, so that backboard 3 be pulled to rotate forward, until elastic band 6 returns to original state, backboard 3 turns to make forward at this time
Children trolley is in sitting posture use state, as shown in figure 4, adjusting position and locking that backrest adjusts band 5, then so as to make this
Children trolley is stablized under sitting posture use state.
Embodiment 3
As shown in Figure 5 and Figure 6, in this embodiment, cloth set 4 does not have elasticity all, uses when children trolley is in lying posture
When state, it includes the side positioned at the left or right side of children trolley with body that the backrest of every side, which adjusts band 5, and elastic component is all
Or the side band body of partial-length, i.e. side band body is whole flexible elastic webbing, alternatively, the side band body of partial-length
For flexible elastic webbing.Specifically, the side of every side includes 51 He of first band body that one end is mutually fixedly connected with body
Second band body 52, the other end of first band body 51 are fixed on vehicle frame 1, and second the other end with body 52, which extends to, to be leaned on
Backboard 3, second band body 52 be elastic component, i.e., second with body 52 be the elastic webbing with certain elasticity.
Remaining is same as Example 1.
In this way when children trolley is in lying posture use state, as shown in figure 5, turn over after 3 stress of backboard, second
Band body 52 is stretched, and in the state being straightened, cloth set 4 is also at the state being straightened at this time, and backrest adjusts band 5 and supports simultaneously
Backboard 3 rear portion and by locking mechanism lock, persistently turn over so as to limit backboard 3, so that the children push away
Vehicle is stablized in lying posture use state.
When the children being located on children trolley are in sitting state or children leave children trolley, i.e., at children trolley
In light condition, at this point, the second band body 52 can be shunk automatically since natural resiliency acts on since backboard 3 is not by external force,
To pull backboard 3 to rotate forward, until the second band body 52 returns to original state, backboard 3 turns to make forward at this time
Children trolley is in sitting posture use state, as shown in fig. 6, adjusting position and locking that backrest adjusts band 5, then so as to make this
Children trolley is stablized under sitting posture use state.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
