[0036] Currently available child seats on the market typically integrate with car seats to provide seating for children. Installing a child seat separately in a car takes up a lot of space, is complicated to install, and requires correct installation to ensure safety. Furthermore, child seats are heavy and difficult to carry, making them inconvenient and laborious to use. They also cannot meet the needs of children throughout their entire life cycle, from infancy to adulthood, and only meet the needs of children at a certain age. Child seats need to be replaced as children grow, failing to realize the technical problem of product growth.

[0037] To solve the above technical problems, such as Figs. 1-3 As shown, this application embodiment 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 the headrest 10, a right side wing of the 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 the adult seat frame 2 is arranged at the top of the slide rail assembly 1 and connected to the slide rail assembly 1 by bolts. The slide rail assembly 1 is used to allow the adult seat frame 2 to slide forward and backward relative to the vehicle body. The slide rail assembly 1 includes at least two slide rails arranged along the front and rear direction of the vehicle body. The slide rail assembly 1 is used as a common forward and backward sliding adjustment component of the automobile seat. The slide rail assembly 1 can use a slide rail that can realize sliding function in the prior art, such as a slide rail disclosed in a Chinese utility model patent with the patent publication number CN218228723U. The structure of the slide rail is not limited in this application, and therefore the specific structure and driving mode of the slide rail will not be described here.

[0039] Specifically, the child seat frame 3 is located in the adult seat frame 2, and the child seat frame 3 is connected to the adult seat frame 2 by a four-bar linkage mechanism 4. The four-bar linkage mechanism 4 is used to allow the child seat frame 3 to adjust the position relative to the adult seat frame 2, including lifting and lowering the child seat frame 3. The four-bar linkage mechanism 4 includes a four-bar lifting structure located on both sides of the child seat frame 3. The four-bar lifting structure connects the child seat frame 3 and the adult seat frame 2 through a connecting rod, and adjusts the connecting rod to make the child seat frame 3 lift or lower relative to the adult seat frame 2. The driving member of the four-bar linkage mechanism 4 can be a motor, which will not be described here. The four-bar linkage mechanism 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 by the upper connecting rod 6, and the adult backrest 7 is connected to the child backrest 8 by a backrest disengaging lock mechanism 9. The backrest disengaging lock mechanism 9 is used to allow the child backrest 8 to be fixed or unlocked relative to the adult backrest 7. The backrest disengaging lock mechanism 9 can use an existing mechanical disengaging lock mechanism, which will not be described here. For example, the disengaging lock function can be realized by using the disengaging lock mechanism disclosed in a Chinese utility model patent with the patent publication number CN221775727U. When adjusting the automobile seat, the two backrests can be fixed or unlocked by the backrest disengaging lock mechanism 9 to facilitate the adjustment.

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

[0042] In a specific embodiment, the other two headrests are also provided with a headrest lifting motor 18, and the output end of the headrest lifting motor 18 is drivingly connected to the headrest for driving the headrest to realize lifting, also in order 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 basin 5 through a seat connection lock 13, and the seat connection lock 13 is used to ensure the stable connection between the child seat basin 5 and the child backrest 8. The seat connection lock 13 is driven by electricity, and the same can adopt the existing technology, which will not be repeated here.

[0044] In a specific embodiment, the child seat basin 5 is connected to the rotating disc 16 through a tilting mechanism 15, and the rotating disc 16 is connected to the child seat frame 3 through a rotating mechanism 17. The tilting mechanism 15 is used to allow the child seat basin 5 to be adjusted in tilting angle relative to the rotating disc 16. The rotating mechanism 17 is used to allow the rotating disc 16 and the child seat basin 5 and the child backrest 8 connected thereto to be adjusted in rotation relative to the child seat frame 3. Among them, the tilting mechanism 15 can be realized by adopting the existing technology, and this application does not limit it, for example, it can be realized by adopting the tilting mechanism 15 involved in a movable car seat with a single column disclosed in a patent with publication number KR20180035228A; the rotating mechanism 17 can be realized by adopting the existing technology, and this application does not limit it, for example, it can be realized by adopting an electric rotating mechanism 17 of a car seat disclosed in a patent with publication number CN216424157U. The tilting mechanism 15 realizes the tilting adjustment function of the child seat, and the rotating mechanism 17 realizes the rotating adjustment function of the child seat.

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

[0046] In a specific embodiment, the automobile seat is electrically connected with an electronic control unit (ECU) of the automobile. Specifically, the electric drive module designed on the automobile seat, such as the headrest lifting motor 18, is linked with the automobile ECU, and through the electric control of the automobile ECU, one-key electric adjustment of the automobile seat in multiple modes is realized, which is convenient to operate and has high intelligent degree. It should be noted that the automobile ECU belongs to the prior art, and the improvement thereof is not involved in the present application, and thus will not be described here.

[0047] The specific use method of the growing automobile seat in the embodiment of the present application is as follows:

[0048] When the four-bar linkage mechanism 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 basin 5 and the angle and distance of the headrest meet the riding requirements of children over 3 years old; when the rotating disc 16 assembly drives the child seat basin 5 to rotate 180°, the four-bar linkage mechanism 4 is lifted to a certain height, the pitch structure changes the angle of the child seat basin 5, and the headrest side wing folding mechanism 12 works, which can meet the riding requirements of the child seat for 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, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features thereof; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
