Figure 1 The position shown in the figure can now transform the original adult seat into a child seat for children to use.
[0042] When the child seat is used and needs to be stored, the control unit 006 presses the storage button, and the first steering engine 41, the second steering engine 412 and the third steering engine 413 drive the base guardrail 012, the back guardrail 014 and the two sides of the pillow 15 to buckle as shown in the figure. Fig.13 In the state shown, the locking button 051 of the lockable rotating shaft 005 is pressed at the same time to buckle the child seat base 011 and the child seat backrest 013 of the child safety seat 001 into a state as shown. Fig.11 Finally, the lifting platform 003 lowers the entire child seat to below the adult seat base 021 and pushes it a short distance toward the backrest to prevent the child safety seat from leaking out, and finally the separation layer 211 is buckled into a Fig.12 As indicated, continue to be used by adults.
[0043] As a possible implementation, a plurality of buttons may be provided on the control unit 006 to respectively control the deployment angles of the first servo 41, the second servo 412 and the third servo 413, so that the base guardrail 012, the back guardrail 014 and the pillow 15 are deployed at different angles so as to be suitable for children of different body shapes.
[0044] As a possible implementation, the transmission ratio of the gear set connected to the first servo 41, the second servo 412 and the third servo 413 can be adjusted according to the servo torque and the locking force at the guardrail required in actual use, mainly to prevent the base guardrail 012, the backrest guardrail 014 and the two sides of the pillow 15 from rotating easily.
[0045] As a possible implementation, the child seat backrest 013 of the child safety seat 001 may be provided with a plurality of safety belt holes, and the fixed positions may be freely selected according to the size of the child using the child.
[0046] This embodiment integrates the child work seat into the rear seat of the car. The adult seat in the rear seat of the car can be transformed into a safety seat for children through simple operations, saving space and without the need for tedious disassembly. In addition, as the child grows older, the seat can adapt to children of different sizes by adjusting the angles of the pillow, base guardrail, and backrest guardrail, thereby increasing its applicability.

3. The lifting mechanism of a rear-row deformable seat of a car according to claim 2, characterized in that: The height difference between the bottom frame (031) and the top frame (032) can be adjusted by controlling the extension and retraction of the lifting hydraulic rod (036); the seat fixing plate (033) is located on the top frame (032) and is connected by a sliding fit; the translation hydraulic rod (037) is fixedly mounted on the top frame (032) at one end away from the top frame slide groove (321), and is fixedly connected to the seat fixing plate (033); the position of the seat fixing plate (033) can be adjusted by controlling the extension and retraction of the translation hydraulic rod (037).
4. The lifting mechanism of a rear deformable seat of a car according to claim 2, characterized in that: When the child safety seat (001) needs to be used, the translation hydraulic rod (037) drives the seat fixing plate (033) to be pushed toward the front of the seat, and at the same time, by driving the lifting hydraulic rod (036) to extend, the top frame (032) is raised, thereby driving the child safety seat (001) to be raised to a specified position, and then the child safety seat (001) is fully unfolded for use; when the child safety seat (001) is not in use, the lifting hydraulic rod (036) is driven to shorten, so that the top frame (032) is lowered, thereby driving the child safety seat (001) to be lowered into the adult seat base (021), and the translation hydraulic rod (037) drives the seat fixing plate (033) to be pushed toward the rear of the seat, thereby fully utilizing the space of the seat base.
