[0036] The child seats currently available on the market in the relevant technology are usually combined with car seats to realize the function of child riding. Installing a child seat separately on the car seat takes up a large space in the car, and the child seat is troublesome to install. The customer needs to install it correctly to ensure its safety during use. In addition, the child seat itself is heavy and not easy to carry. It is troublesome and laborious to use, and it cannot meet the use problems of the entire life cycle from childhood to adulthood. It can only meet the use of children in a certain age group. The child seat needs to be replaced as the age increases, and the technical problem of the product not being able to realize the concept of growth.

[0037] In order to solve the above technical problems, Figure 1-3 As shown, an embodiment of the present application provides a growth-type car seat, including a slide rail assembly 1, an adult seat frame 2, a child seat frame 3, an adult backrest 7, a child backrest 8, a left side wing of a headrest 10, a right side wing of a headrest 11 and a child seat basin 5.

[0038] In a specific embodiment, the slide rail assembly 1 is connected to the vehicle body by bolts, and an adult seat frame 2 is arranged on the top of the slide rail assembly 1, and the adult seat frame 2 is connected to the slide rail assembly 1 by bolts, wherein the slide rail assembly 1 is used to allow the adult seat frame 2 to slide forward and backward relative to the vehicle body, and the slide rail assembly 1 includes at least two slide rails arranged along the front and rear directions of the vehicle body. The slide rail assembly 1 is a commonly used front and rear sliding adjustment component for automobile seats. The slide rail assembly 1 can be implemented by a slide rail that can realize a sliding function in the prior art, such as a car seat slide rail disclosed in a Chinese utility model patent with patent publication number CN218228723U. The present application does not limit its structure here, so its specific structure and driving method are not repeated here.

[0039] Specifically, the child seat frame 3 is located inside the adult seat frame 2, and the child seat frame 3 is connected to the adult seat frame 2 via a four-bar linkage 4. The four-bar linkage 4 is used to allow the child seat frame 3 to be adjusted relative to the adult seat frame 2, including lifting and lowering the child seat frame 3. The four-bar linkage 4 includes a four-bar lifting structure located on both sides of the child seat frame 3, wherein the four-bar lifting structure connecting rods connect the child seat frame 3 and the adult seat frame 2, and by adjusting the connecting four-bars, the child seat frame 3 is lifted or lowered relative to the adult seat frame 2. The driving member of the four-bar linkage 4 may be a motor, etc., which will not be described in detail here. The four-bar linkage 4 satisfies the functions of extending, lifting and lowering the child seat.

[0040] In a specific embodiment, the adult seat frame 2 is connected to the adult backrest 7 through the upper connecting rod 6, and the adult backrest 7 is connected to the child backrest 8 through the backrest clutch lock mechanism 9. The backrest clutch lock mechanism 9 is used to allow the child backrest 8 to be fixed or unlocked relative to the adult backrest 7. The backrest clutch lock mechanism 9 can adopt an existing mechanical clutch lock mechanism, which is also not described in detail in this application. For example, a seat for a vehicle and a vehicle having the same disclosed in a Chinese utility model patent with patent announcement number CN221775727U can be used to realize the clutch lock function. When adjusting the car seat, the two backrests can be fixed or unlocked by the backrest clutch lock mechanism 9 to facilitate adjustment.

[0041] In a specific embodiment, a left side wing 10 of a headrest and a right side wing 11 of a headrest are provided on the top of the child backrest 8. The left side wing 10 of the headrest and the right side wing 11 of the headrest are connected to the child backrest 8 through a headrest wing folding mechanism 12; the headrest wing folding mechanism 12 is used to allow the left side wing 10 of the headrest and the right side wing 11 of the headrest to be folded and adjusted relative to the child backrest 8. The headrest wing folding mechanism 12 can adopt an existing wing folding structure, which is not described in detail in this application. For example, an electric wing folding mechanism disclosed in a Chinese utility model patent with patent announcement number CN112937397A can be adopted to realize the wing folding function. When adjusting the car seat, the distance and angle between the left side wing 10 of the headrest and the right side wing 11 of the headrest can be adjusted by the headrest wing folding mechanism 12 to adapt to the use of passengers of different ages. The headrest wing folding mechanism 12 realizes the function of adjusting the wing of the child backrest 8.

[0042] In a specific embodiment, a headrest lifting motor 18 is further provided at the lower portion of the other two headrests. The output end of the headrest lifting motor 18 is connected to the headrest for driving the headrest to be raised and lowered, also to meet the riding needs of passengers of different ages.

[0043] In a specific embodiment, the child backrest 8 is connected to the child seat pan 5 via a seat connection lock 13, and the seat connection lock 13 is used to ensure a stable connection between the child seat pan 5 and the child backrest 8. The seat connection lock 13 is electrically driven and can also adopt existing technology, which will not be repeated here.

[0044] In a specific embodiment, the child seat seat pot 5 is connected to the turntable 16 via a pitch mechanism 15, and the turntable 16 is connected to the child seat seat frame 3 via a rotating mechanism 17. The pitch mechanism 15 is used to allow the child seat seat pot 5 to adjust the pitch angle relative to the turntable 16. The rotating mechanism 17 is used to allow the turntable 16 and the child seat pot 5 and the child backrest 8 connected thereto to rotate and adjust relative to the child seat seat frame 3. Among them, the pitch mechanism 15 can be implemented by using the existing technology, and this application does not limit this. For example, it can be implemented by using the pitch mechanism 15 involved in the movable car seat with a single column disclosed in Patent Publication No. KR20180035228A; the rotating mechanism 17 can be implemented by using the existing technology, and this application does not limit this. For example, it can be implemented by using an electric rotating mechanism 17 for a car seat disclosed in Patent Publication No. CN216424157U. The pitch mechanism 15 realizes the pitch adjustment function of the child seat, and the rotating mechanism 17 realizes the rotation adjustment function of the child seat.

[0045] In a specific embodiment, the car seat further comprises a five-point safety belt buckle 14, which is fixed to the child seat pan 5 by bolts and is used to connect the five-point safety belt.

[0046] In a specific embodiment, the car seat is electrically connected to the electronic control unit (ECU) of the car. Specifically, the electric drive module designed on the car seat, such as the headrest lifting motor 18, is linked to the car ECU. Through the electric control of the car ECU, the multi-mode one-button electric adjustment of the car seat is realized, which is convenient to operate and highly intelligent. It should be noted that the car ECU belongs to the prior art, and this application does not involve improvements thereto, so it will not be repeated here.

[0047] The specific method of using the growth-type car seat in the embodiment of the present application is as follows:

[0048] When the four-bar linkage 4 lifts the child seat frame 3 to the highest state, the headrest side wing folding mechanism 12 works, so that the height of the child seat pan 5 and the angle and distance of the headrest meet the riding needs of children over 3 years old; when the turntable 16 assembly drives the child seat pan 5 to rotate 180°, the four-bar linkage 4 is lifted to a certain height, the pitch structure drives the child seat pan 5 to change its angle, and the headrest side wing folding mechanism 12 works, which can meet the riding needs of children under 3 years old.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
