The angles of the first servo 41, the second servo 412 and the third servo 413 are divided into a folding angle and an unfolding angle, wherein the folding angle is a fixed value and the unfolding angle can be adjusted. The lifting hydraulic rod 036 and the translation hydraulic rod 037 are divided into an unfolded length and a stowed length, and both are fixed values.

[0041] The seat is usually kept Fig.12 The state shown can be used normally by adults at this time;

[0042] When the child seat is needed, the separation layer 211 is first opened, and the control unit 006 presses the unfolding button, and the seat will be unfolded from the Fig.11 In the state shown, the entire child seat is lifted and pushed outward for a short distance by the lifting platform 003, and at the same time, the first servo 41, the second servo 412 and the third servo 413 drive the base guardrail 012, the backrest guardrail 014 and the two sides of the pillow 15 to unfold. At this time, the locking button 051 of the lockable shaft 005 is pressed to adjust the angle between the child seat base 011 and the child seat backrest 013 of the child safety seat 001. When an angle suitable for children is found, the locking button 051 can be released, and finally the state shown in FIG. Figure 1 The position shown in the figure can now transform the original adult seat into a child seat for children to use.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] The utility model integrates the child work seat into the rear seat of the car, and can transform the adult seat in the rear seat of the car into a safety seat for the child through simple operation, thus saving space and not requiring tedious disassembly, so that the user can use it conveniently. In addition, as the child ages, the seat can adapt to children of different sizes by adjusting the angles of the headrest, the base guardrail, and the back guardrail, thereby increasing its applicability.
