[0044] It should be noted that the rotating pin 103a and the positioning column 303a are both installed on the seat base. The seat base is fixed on the rear seat of the car and is used to connect and install the seat through this chassis mechanism. A positioning hole and a slot are provided on the base. The slot is provided at the center of the base. The rotating mechanism 1 connects the two by inserting the rotating pin 103a along the slot. The positioning holes are evenly distributed around the slot. In this embodiment, there are four positioning holes, each located in the up, down, left and right directions of the slot. By increasing the number of positioning holes, more angles of seat position limitation can be achieved.

[0045] Preferably, two sliding rails 101 are provided on the upper surface of the rotating mechanism 1, corresponding to the guide rails 201 of the sliding mechanism 2 respectively, and an auxiliary rail 104 is provided between the two sliding rails 101, for limiting the position of the sliding mechanism 3 to prevent the sliding mechanism 2 from derailing in the vertical direction, and the first handle 202 is installed on both sides of the two sliding rails 101, and the lower chassis 103 is fixedly installed below the rotating mechanism 1, and the first handle 202 is installed on both sides of the two sliding rails 101, and the first handle 202 is fixedly connected to the transmission plate 301, and the other end of the transmission plate 301 is inserted into the center of one end of the locking member 302, and one end of the tension spring 304 is fixed to the transmission plate 301, and the other end is fixed to the locking member 302 on the same side, for resetting the first handle 202.

[0046] Preferably, the unlocking steps of the rotating mechanism 1 are: pulling the first handle 202 - driving the transmission plate 301 - the two locking members 302 separate - the locking button 302a disengages from the button groove 305 - the locking member 302 lifts - the positioning member 303 lifts synchronously - the positioning column 303a lifts - the rotating mechanism 1 is unlocked; the unlocking steps of the sliding mechanism 2 are: pressing the pressing block 401a and pulling the second handle 204 at the same time - the pressing block 401a is forced to insert into the sliding mechanism 2 - the control member 401 penetrates - the limiting column 402 rises - the limiting column 402 disengages from the column slot 404 - the sliding mechanism 2 is unlocked.

[0047] Preferably, the second handle 204 is engaged with the main body of the sliding mechanism 4 through the protrusion 205. After unlocking, pulling the second handle 204 can pull the entire sliding mechanism 4 to slide along the track.

[0048] Preferably, after the sliding mechanism 2 is unlocked, that is, after the pressing block 401a is pressed, the bite 403b of the block 403 slides from one side of the right-angle protrusion 401b-1 to the other side. Since the other side is a right-angle side, the outer end of the bite 403b will abut against the right-angle protrusion 401b-1. At this time, the pressing block 401a will remain in the pressed state, which can facilitate manual pulling of the sliding mechanism 2 to slide out along the track. Due to the memory function of the block 403, this process There is no need to continue pressing the pressing block 401a. When the sliding mechanism 2 is reset, the limiting protrusion 403c will pass through the bayonet 406. The outer end of the bayonet 406 has a partial slope. During the resetting process, the bayonet 406 will gradually lift the limiting protrusion 403c and the block 403, so that the bite 403b can cross the right-angle protrusion 401b-1 and reset. At the same time, the pressing block 401a is also reset, and the limiting column 402 is reinserted into the column slot 404, and the resetting is completed.

[0049] Preferably, in this embodiment, the sliding mechanism 2 can only move in one direction, that is, a direction that is convenient for carrying out or placing the child. When the child safety seat of the utility model is installed in the back seat of a car, the best sliding direction is toward the corresponding door, which makes it easy to slide the seat out, thereby making it easier to carry out or place the child, avoiding the inconvenience caused by the parents bending over.

[0050] In summary, the child safety seat chassis mechanism with side sliding and rotating functions of the utility model can meet the use scenarios of most child seats through the multi-adjustable function design that can rotate and move sideways. It is also more convenient for parents to pick up or place children, and the overall use experience and safety performance of the seat are greatly improved. In addition, it is also equipped with two sets of independent locking and unlocking methods, which effectively improves the stability of the seat installation and adjustment and the response capability in emergency situations, and the safety is further improved.

Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
