[0031] The present application provides a child safety seat, as shown in FIG. 1A and FIG. 1B, which comprises a base assembly 01 and a seat back assembly 02, the seat back assembly 02 is slidingly arranged on the base assembly 01 and can be translated towards the left and right sides of the base assembly 01, or in other words, can be translated towards the side where the vehicle door is located, so that the child can be put into or taken out of the child safety seat.

[0032] In some embodiments, the seat back assembly 02 can also rotate relative to the base assembly 01 to realize, for example, forward installation, reverse installation, lateral installation towards the vehicle door, etc., to meet different seating needs of children.

[0033] In combination with FIG. 2, a wire assembly 40 is usually arranged between the seat back assembly 02 and the base assembly 01, which can specifically include mechanical transmission wires and / or electrically conductive wires, such as steel wire ropes 42, electric wires 41, etc. The wire assembly 40 is used for mechanical transmission or electrical connection between the seat back assembly 02 and the base assembly 01. In the related art, during the rotation or lateral translation of the seat back assembly 02 relative to the base assembly 01, the wire assembly 40 can be wound and wire jammed, resulting in the corresponding mechanical transmission function or electrical connection function cannot be realized, the child safety seat cannot work normally, and even can cause safety hazards.

In a specific embodiment, the base assembly 01 constitutes the fixed part 10, and the backrest assembly 02 constitutes the movable part 20. It can be understood that in other embodiments, the fixed part 10 and the movable part 20 can also be constituted by other modules that are slidably connected with each other in the child safety seat. Through the wire passing hole 3b and / or the wire passing groove 3a, the present application can limit the wire assembly 40 and guide the movement direction of the wire assembly 40, thereby reducing the risk of the wire assembly 40 being wound and stuck during the displacement of the movable part 20 relative to the fixed part 10, and the overall structure is simple, easy to disassemble and maintain, and low in processing and use cost.

[0035] In some embodiments, in combination with FIGS. 2, 3A, and 3B, the wire assembly 40 comprises an electric wire 41, the sliding plate 30 is provided with a wire passing groove 3a, the electric wire 41 is movably arranged in the wire passing groove 3a, one end of the electric wire 41 is connected with the fixed part 10, and the other end of the electric wire 41 is connected with the movable part 20, for realizing the electrical connection between the fixed part 10 and the movable part 20.

[0036] In some embodiments, the length direction of the wire passing groove 3a is the sliding direction of the movable part 20, and when the movable part 20 slides synchronously with the sliding plate 30, the electric wire 41 can smoothly slide in the wire passing groove 3a. In other embodiments, the wire passing groove 3a can also be arranged obliquely relative to the sliding direction of the movable part 20, for example, at an angle less than or equal to 30°, as long as the electric wire 41 can be partially arranged in the wire passing groove 3a and the wire passing groove 3a does not pull the electric wire 41 during the sliding of the sliding plate 30, and the electric wire 41 can smoothly slide in the wire passing groove 3a.

[0037] In some embodiments, the length of the wire passing groove 3a is greater than or equal to the sliding stroke of the movable part 20, so as to avoid the two ends of the wire passing groove 3a from pulling the electric wire 41.

[0038] In some embodiments, the wire passing groove 3a is arranged as a square groove, which is regular in structure and easy to process and form.

[0039] In some embodiments, as shown in FIG. 4, the fixed part 10 is provided with a slip ring device 51, and the electric wire 41 includes a first conductive section 411 and a second conductive section 412.

[0043] In some embodiments, the steel wire rope 42 and the electric wire 41 are arranged side by side in the direction perpendicular to the sliding direction of the movable part 20 to prevent interference between different wires.

[0044] In some embodiments, the side of the wire passing hole 3b facing the adjusting handle 21 is arranged in an arc shape to reduce the friction resistance of the steel wire rope 42.

[0045] In some embodiments, the wire passing hole 3b is arranged at one end of the wire passing groove 3a along the sliding direction of the movable part 20 and communicates with the wire passing groove 3a. The steel wire rope 42 can be first threaded in the wire passing groove 3a and then pulled tight and positioned in the wire passing hole 3b, which is beneficial to reduce the processing difficulty and assembly difficulty.
