[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0031] The present application provides a child safety seat, such as Figure 1A , Figure 1B As shown, it includes a base component 01 and a seat back component 02. The seat back component 02 is slidably set on the base component 01 and can be translated toward the left and right sides of the base component 01, or can be translated toward the side where the vehicle door is located, so that a child can be placed in 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 achieve, for example, forward installation, reverse installation, side installation toward the car door, etc., to meet the different riding needs of children.

[0033] Combination Figure 2 As shown, a wire assembly 40 is often provided between the backrest assembly 02 and the base assembly 01. The wire assembly 40 may specifically include mechanical transmission wires and / or electrical conductive wires, such as a steel wire rope 42, an electric wire 41, etc. The wire assembly 40 is used for mechanical transmission or electrical connection between the backrest assembly 02 and the base assembly 01. In the related art, during the rotation or lateral translation of the backrest assembly 02 relative to the base assembly 01, the wire assembly 40 may be entangled or stuck, resulting in the inability to realize the corresponding mechanical transmission function or electrical connection function, the child safety seat cannot work properly, and may even cause safety hazards.

[0034] In order to solve or at least partially alleviate the problem of the wire assembly 40 being entangled and stuck, the present application further provides a wiring structure of a child safety seat, such as Figure 2-Figure 7As shown, the wiring structure of the child safety seat includes a fixed part 10, a movable part 20, a slide plate 30 and a wire assembly 40. The slide plate 30 is slidably connected to the fixed part 10, and the movable part 20 is connected to the slide plate 30 and is suitable for sliding relative to the fixed part 10 synchronously with the slide plate 30. The slide plate 30 is provided with a wire hole 3b and / or a wire groove 3a. One end of the wire assembly 40 is connected to the fixed part 10, and the other end passes through the wire hole 3b or the wire groove 3a to connect with the movable part 20. In a specific embodiment, the base assembly 01 constitutes the fixed part 10, and the seat back assembly 02 constitutes the movable part 20. It can be understood that in some other embodiments, the fixed part 10 and the movable part 20 can also be respectively constituted by two other modules in the child safety seat that are slidably connected to each other. The present application uses the wire hole 3b and / or the wire groove 3a to 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 entangled or stuck during the displacement of the movable part 20 relative to the fixed part 10. The overall structure is simple, easy to disassemble and maintain, and has low processing and use costs.

[0035] In some embodiments, in combination Figure 2 , Figure 3A , Figure 3B The wire assembly 40 includes an electric wire 41. A wire groove 3a is provided on the slide plate 30. The electric wire 41 is movably arranged in the wire groove 3a. One end of the electric wire 41 is connected to the fixed part 10, and the other end is connected to the movable part 20, so as to realize the electrical connection between the fixed part 10 and the movable part 20.

[0036] In some embodiments, the length direction of the wire groove 3a is the sliding direction of the movable part 20, and when the movable part 20 and the slide plate 30 slide synchronously, the wire 41 can slide smoothly in the wire groove 3a. In other embodiments, the wire groove 3a can obviously be set at an angle relative to the sliding direction of the movable part 20, for example, at an angle of less than or equal to 30°, as long as it is ensured that the wire 41 can be partially set in the wire groove 3a to avoid air, and the wire groove 3a will not pull the wire 41 during the sliding process of the slide plate 30, and the wire 41 can slide smoothly in the wire groove 3a.

[0037] In some embodiments, the length of the wire groove 3 a is greater than or equal to the sliding stroke of the movable portion 20 to prevent the two ends of the wire groove 3 a in the length direction from pulling the wires 41 .

[0038] In some embodiments, the wire groove 3a is configured as a square groove with a regular structure and is easy to process and shape.

[0039] In some embodiments, in combination Figure 4The fixed part 10 is provided with a slip ring 51, and the wire 41 includes a first conductive segment 411 and a second conductive segment 412. The first conductive segment 411 is provided on one side of the slip ring 51 and connected to the fixed part 10, and the second conductive segment 412 is provided on the other opposite side of the slip ring 51 and passes through the wire slot 3a to connect to the movable part 20. Figure 3A and Figure 3B The first conductive segment 411 is not shown. In a specific embodiment, the wire 41 is movably arranged in the slip ring 51 , and when the movable part 20 rotates relative to the fixed part 10 , the wire 41 can rotate adaptively.

[0040] In some embodiments, along the sliding direction of the movable part 20, the slip ring 51 is centrally arranged relative to the fixed part 10, and a guide structure 11 suitable for limiting the second conductive segment 412 is also arranged on the fixed part 10, and the guide structure 11 is arranged on one side of the slip ring 51 along the sliding direction of the movable part 20. When the movable part 20 slides away from the center of the fixed part 10, Figure 3B As shown, under the action of the guide structure 11, the second conductive segment 412 passes through the wire slot 3a upwards and is connected to the movable part 20 at the side closer to the deviation direction of the movable part 20, thereby solving the problem that part of the wire 41 is exposed to the air after the second conductive segment 412 directly passes through the wire slot 3a upwards above or near the slip ring 51.

[0041] In some embodiments, in combination Figure 5 The fixing portion 10 is provided with a slot 1a suitable for installing the slip ring 51, and a guide slot 11a is provided on the slot wall of the slot 1a. The fixing portion 10 is also provided with a guide opening 11b spaced from the guide slot 11a. The guide slot 11a and the guide opening 11b together constitute a guide structure 11, which has a simple structure and is easy to process and form.

[0042] In some embodiments, in combination Figure 2 , Fig. 6A , Figure 6B , Figure 7 The movable part 20 is provided with an adjustment handle 21 which can be the angle adjustment handle of the backrest assembly 02. The wire assembly 40 includes a steel wire rope 42. The slide plate 30 is provided with a wire hole 3b. The steel wire rope 42 is movably passed through the wire hole 3b. One end of the steel wire rope 42 is connected to the fixed part 10, and the other end is connected to the adjustment handle 21. When the movable part 20 slides and translates laterally, the steel wire rope 42 can move in the wire hole 3b. The wire hole 3b limits the steel wire rope 42 to prevent it from being entangled or stuck.

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

[0044] In some embodiments, the side of the wire hole 3 b facing the adjustment handle 21 is configured to be arc-shaped to reduce the friction resistance to the wire rope 42 .

[0045] In some embodiments, the wire hole 3b is arranged at one end of the wire groove 3a along the sliding direction of the movable part 20 and communicates with the wire groove 3a. The wire rope 42 can be firstly passed through the wire groove 3a, and then tightened and limited in the wire hole 3b, which is conducive to reducing the difficulty of processing and assembly.
