detailed description

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIGS. 1 to 4 , the child safety seat of the present invention includes a base 1 , a seat panel assembly 2 and a backrest assembly 3 .

The base 1 extends along the front-to-back direction and is used to connect with the car seat. The seat panel assembly 2 and the backrest assembly 3 are all arranged on the base 1. The backrest assembly 3 is located at the rear of the seat panel assembly 2. The base 1, the seat panel assembly 2, The three components of the backrest assembly 3 are rotationally connected in two phases, wherein the two rotationally connected components are rotationally connected through the first shaft 41, and the first shaft 41 is slidably arranged in the two rotationally connected parts on one of the components. The first shaft 41 can be fixedly arranged on the other part of the two parts that are rotatably connected; it can also be set rotatably relative to the other part of the two parts that are rotatably connected. At this time, the base 1 and the seat plate A slider crank mechanism is formed between the component 2 , the backrest component 3 and the first shaft 41 . In this way, the relative positions among the base 1 , the seat panel assembly 2 and the backrest assembly 3 can be adjusted, so that the child safety seat can be in different use states.

Specifically, the child safety seat has at least a sitting posture and a flat lying posture. When the child safety seat is in the sitting posture, both the seat panel assembly 2 and the backrest assembly 3 extend obliquely in the up and down direction, and the direction of their inclination On the contrary, a first angle is formed between the seat panel assembly 2 and the backrest assembly 3; children can sit and stand in the space formed by the seat panel assembly 2 and the backrest assembly 3; Both the component 2 and the backrest component 3 extend along the front-to-back direction, forming a second included angle between the seat panel component 2 and the backrest component 3, and the second included angle is much larger than the first included angle, children can sit between the seat panel component 2 and the backrest component 3 to lie down in the space formed, thereby improving the comfort of the child safety seat.

The child safety seat also includes a locking mechanism for locking the child safety seat in a sitting position and a flat-lying use state and an unlocking mechanism for unlocking the locking mechanism. The locking mechanism can be arranged on the base 1, the seat panel assembly 2 and the backrest Between any two connected parts of the three parts of component 3, after the locking mechanism is unlocked by the unlocking mechanism, the child safety seat can be switched between the sitting position use state and the lying use state. The locking mechanism and the unlocking mechanism The specific structures are not the technical points to be protected by this patent, and the structures in the prior art can be used.

A specific embodiment, the base 1 and the backrest assembly 3 are rotatably connected through the second shaft 42, one end of the seat board assembly 2 and one end of the backrest assembly 3 are rotatably connected through the third shaft 43, and one end of the base 1 It is rotatably connected with the seat plate assembly 2 through a first shaft 41 , and the first shaft 41 is slidably arranged on the seat plate assembly 2 . In this embodiment, the first shaft 41 is fixed on the base 1 .

The way in which the first shaft 41 is slidably arranged on the seat plate assembly 2 is as follows: the seat plate assembly 2 is provided with a chute 21 extending in the front-rear direction, and the first shaft 41 passes through the chute 21 and can move along the chute. The length extension of 21 is slidably set.

The locking mechanism in this embodiment is arranged at the rotational connection between the seat panel assembly 2 and the backrest assembly 3 .

As shown in Figures 1 and 2, the child safety seat is in a sitting position. At this time, the seat panel assembly 2 and the backrest assembly 3 both extend obliquely in the up and down direction, and the inclination directions of the two are opposite. The first axis 41 is in the The front end of the chute 21 is located in the chute 21; when the child safety seat is converted from a sitting position to a flat use state, the locking mechanism is first unlocked, and then the backrest assembly 3 is moved backward and downward around the second axis 42 Turning over, when the backrest assembly 3 is turned backwards and downwards, the third shaft 43 is moved toward the front of the child safety seat and moved upwards, so that the seat panel assembly 2 also moves forward and turned down around the third shaft 43, This makes the first shaft 41 slide backward along the length extension direction of the chute 21 in the chute 21 until the first shaft 41 slides to the rear end of the chute 21, and the locking mechanism locks again. At this time, the seat plate assembly 2 and The backrest assemblies 3 all extend along the front and rear directions, and the child safety seat is in a flat use state, as shown in Fig. 3 and Fig. 4 .

When the child safety seat is converted from the lying state to the sitting state, it is only necessary to unlock the locking mechanism and then turn the backrest assembly 3 upward and forward around the second axis 42. When the backrest assembly 3 is turned upward and forward, Make the third shaft 43 move toward the rear of the child safety seat and move downwards, so that the seat panel assembly 2 also moves backwards and turns upwards around the third shaft 43, which makes the first shaft 41 move along the chute 21 The length extension direction of the chute 21 slides forward until the first shaft 41 slides to the front end of the chute 21. At this time, the seat panel assembly 2 and the backrest assembly 3 both extend in the direction of inclination up and down, and the child safety seat is in the sitting position. In use state, as shown in Figure 1 and Figure 2.

When the above-mentioned child safety seat is used in a sitting position, when it is used in a flat position, and when it is switched between the use position in a sitting position and a flat position, the base 1 is always kept at the same position, and only the seat panel assembly 2 and the backrest are adjusted. The relative position of component 3 is enough.

The above descriptions about directions are all defined according to the direction observed by the child sitting on the child safety seat. When the child sits on the child safety seat, the direction facing the face is the front, and the left and right sides of the child are facing forward. The side is the left-right direction in this embodiment.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to enable those familiar with this technology to understand the content of the present utility model and implement it accordingly, and not to limit the protection scope of the present utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
