[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figures 1-4 As shown, the present invention provides an integrated car seat suitable for both adults and children, comprising: The child seat 1 is mounted rearward on the backrest frame 3 of the front adult seat 2, facing the rear adult seat. The front adult seat 2 and the child seat 1 can be used interchangeably. When the front adult seat 2 is adjusted to a comfortable position, the child seat 1 cannot be activated; When the backrest frame 3 rotates forward to adjust, the linkage mechanism drives the child seat 1 to unfold.

[0022] The technical scheme fills the blank of reverse integrated seat, and gives consideration to safety and convenience. The reverse installation of the integrated seat for children under 4 years old is realized for the first time, and the technical blank in the prior art is solved. The comfortable position is locked in the child mode, and the unique safety of the child riding posture is ensured. The linkage expansion design saves the manual assembly step, and the operation efficiency is improved.

[0023] In the present application, the linkage mechanism is a connecting rod linkage mechanism 4, a gear linkage mechanism or a belt linkage mechanism. In the technical scheme, various linkage modes can be selected according to the space, cost or design requirements of the vehicle, expand the product application scenarios, and enhance the market compatibility, flexibility and adaptability of the technical scheme.

[0024] In the present application, as shown in Figures 13-15 The connecting rod linkage mechanism 4 comprises: an angle adjuster assembly 5 installed on the backrest framework 3, when unlocked, the backrest framework 3 rotates around the angle adjuster assembly 5; a connecting rod assembly 6 comprising a first connecting rod 7, a second connecting rod 8 and a third connecting rod 9 hingedly connected to each other, the first connecting rod 7 is hingedly connected to the backrest framework 3, and the hinged portion forms a first rotation point 10, one end of the first connecting rod 7 is hingedly connected to the child seat 1, and the other end is hingedly connected to one end of the second connecting rod 8, and the hinged portion forms a second rotation point 11, the other end of the second connecting rod 8 is hingedly connected to one end of the third connecting rod 9, and the hinged portion forms a third rotation point 12, the other end of the third connecting rod 9 is hingedly connected to the angle adjuster lower connecting plate 21 of the angle adjuster assembly 5; When the angle adjuster assembly 5 (which can be a conventional angle adjuster assembly 5 in the art) is unlocked, when the backrest framework 3 rotates around the angle adjuster assembly 5, the connecting rod assembly 6 transmits the rotating motion of the backrest framework 3 to the child seat 1, and drives the child seat 1 to expand from the storage position to the reverse supporting child riding position. Specifically, as shown in Figures 14-15 The backrest framework 3 rotates forward around the angle adjuster assembly 5, the first rotation point 10 moves forward with the backrest framework 3, and the two ends of the second connecting rod 8 rotate around the second rotation point 11 and the third rotation point 12 at the hinged portions of the first connecting rod 7 and the third connecting rod 9, respectively, drive the second rotation point 11 to move upward, and then drive the first connecting rod 7 to rotate, and finally drive the child seat 1 to rotate and expand. When stored, the motion process is reversed, and this will not be described again.

[0025] In the technical scheme, the stable transmission of motion is realized through the multi-connecting-rod hinged structure, the position accuracy of the child seat 1 from storage to expansion is ensured, the safety and stability are improved, the mechanical structure is durable, and no fault is found after multiple tests.

[0026] As shown in Figure 5 , 13As shown in Figure -15, the installation location of the angle adjuster assembly 5 is illustrated as follows: The angle adjuster assembly 5 mainly includes an upper connecting plate 22 for the angle adjuster, which is installed on the backrest frame 3; The lower connecting plate 21 of the angle adjuster is welded to it through the angle adjuster; then the linkage mechanism of the child seat 1 is assembled, and the unlocking piece 19 and the limiting piece 20 are welded to achieve the function of unfolding the child seat 1.

[0027] For the adjuster assembly 5, any standard adjuster assembly from the automotive seat industry can be selected; no special requirements are specified.

[0028] In this invention, the backrest frame 3 is provided with an unlocking handle 13, which is connected to the unlocking plate 19 in the angle adjuster assembly 5 via a pull cable 14. Pressing down on the unlocking handle 13 causes the unlocking plate 19 to be pulled up via the pull cable 14, thus completing the unlocking process. In this technical solution, the unlocking process is simplified to a single step of "pressing down the handle," reducing the user's learning curve; the pull cable 14 transmission structure is concealed and reliable, preventing accidental unlocking and improving safety.

[0029] In this invention, the front adult seat 2 is adjusted to a comfortable position via a locking gas spring 15. In this technical solution, the locking gas spring 15 can be any conventional gas spring with a locking function found in the art; no special requirements are placed on it. The locking gas spring 15 provides a linear, smooth backrest adjustment experience, improving adult seating comfort; the locking function ensures the adjusted posture is fixed, preventing accidental movement and enhancing safety.

[0030] In this invention, such as Figures 5-7 As shown, after unlocking the locking gas spring 15 by pulling up the unlocking handle 16, the adult seating position can be adjusted.

[0031] like Figures 8-9 As shown, in this invention, the backrest frame 3 is provided with a front stop point 17 and a rear stop point 18 to limit the adjustment of the comfort state. This technical solution has clear adjustment boundaries to prevent excessive backrest adjustment that could cause structural damage, while ensuring that the child mode is only activated in the designed posture (avoiding accidental triggering in a comfortable position), thus improving system safety and reliability.

[0032] like Figures 10-11The diagram shows the principle of the child seat 1 in its unlocked and folded states in this invention. By pressing down the unlocking handle 13, the cable 14 is driven to pull up the unlocking plate 19, completing the unlocking action. Pushing the backrest frame 3 forward moves the first rotation point 10 forward and the second rotation point 11 upward, causing the first connecting rod 7 to unfold the child seat 1. After the backrest frame 3 is adjusted to the appropriate position, the rear stop 18 blocks and limits the lower connecting plate 21 of the adjuster, thus completing the unfolding. The folding action is the reverse of the unfolding action; that is, it is simply the reverse operation of the unfolded state.

[0033] like Figure 12 As shown, this invention illustrates the principle that the child seat 1 cannot be activated when an adult is seated in a comfortable position, as detailed below: When the adult seat is adjusted to the comfort position, the danger of accidental activation of the child seat 1 is prevented by adding a limiting piece 20 to the backrest. The child seat 1 needs to be unlocked by rotating the angle adjuster unlock piece 19 at least 20°. However, when the comfort position is reached, it has already been rotated 16°. If it tries to rotate another 20°, it will be blocked by the limiting piece 20 and the seat frame stop point 23. Therefore, the child seat 1 cannot reach the unlocking angle and cannot be activated.

[0034] The above description is merely a preferred embodiment of the present invention. However, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention should be covered within the scope of protection of the present invention.
