Detailed Description

The utility model is further described in the following with specific embodiments in conjunction with the accompanying drawings, see fig. 1-4:

example one

Referring to the attached figure 1, the automobile child safety seat comprises a backrest framework 1 and a base framework 2 which are hinged with each other, a driving mechanism is arranged between the backrest framework 1 and the base framework 2, the driving mechanism comprises a driving seat 3 and a screw rod 4 screwed in the driving seat 3, the tail end of the screw rod 4 is rotatably arranged in the screw rod seat 5 and is driven by the motor 6, a bearing can be added in the screw rod seat 5 to ensure that the screw rod 4 can better rotate, the outer ends of the driving seat 3 and the screw rod seat 5 are respectively hinged with the backrest framework 1 and the base framework 2, the adjusting mechanism further comprises a control mechanism for controlling the starting and stopping of the motor 6, the motor 6 is a bidirectional motor, and the motor 6 drives the backrest framework 1 to rotate around the base framework 2 in a reciprocating mode through the lead screw control mechanism when rotating, so that the stepless adjusting function of the backrest angle is achieved.

Example 2

Comparing with the attached fig. 2 and fig. 3, on the basis of the embodiment 1, a guiding mechanism is further added to increase the stability during adjustment: actuating mechanism sets up the one side between back skeleton 1 and base skeleton 2, and its opposite side is provided with guiding mechanism, guiding mechanism includes guide holder 7 and the guide bar 8 of smooth establishment in guide holder 7, the outer end of guide holder 7, guide bar 8 is articulated with back skeleton 1, base skeleton 2 respectively. When the motor 6 drives the screw rod 4 to adjust the angle of the backrest, the guide rod 8 slides in the guide seat 7.
