The shaking wires will pull the components connected at both ends and cause collision interference with other wires. They may also scratch the base shell, resulting in a shortened service life of the wires, thereby affecting the stability and safety of the child safety seat. Utility Model Content

[0036] After the wire harness limiting plate 4 is installed on the rotating disk 3, a wiring space for accommodating and limiting the bundled wires 7 is formed between the wire harness limiting plate 4 and the rotating disk 3, and the wire segment portion of the bundled wires 7 is located in the wiring space; further, the side of the wire harness limiting plate 4 facing the rotating disk 3 is the inner side, and the side of the wire harness limiting plate 4 facing away from the rotating disk 3 is the outer side.

[0037] Preferably, in this embodiment, the wire harness limiting plate 4 is connected to the rotating disk 3 by a bolt structure.

[0038] Furthermore, in this embodiment, a countersunk hole 45 is provided on the wire harness limiting plate 4, and the countersunk hole 45 is located on the side of the wire harness limiting plate 4 away from the rotating disk 3, that is, the outer side surface of the wire harness limiting plate 4. The countersunk hole 45 is used to keep the outer side surface of the wire harness limiting plate 4 smooth after the wire harness limiting plate 4 is connected to the rotating disk 3 through a bolt structure, and the head of the bolt can be accommodated in the countersunk hole 45; not indicated in the figure, the wire harness limiting plate 4 is also provided with a countersunk protrusion matching the countersunk hole 45, the countersunk protrusion is located on the inner side surface of the wire harness limiting plate 4, the countersunk hole 45 is coaxially arranged with the countersunk protrusion, and the countersunk hole 45 is partially in the countersunk protrusion.

Specifically, the wire viewing holes 46 are waist-shaped holes, and the wire viewing holes 46 are used for the observer to clearly see the status of the bundled wires 7 in the harness space.

[0040] Furthermore, in this embodiment, twenty wire viewing through holes 46 are provided on the wire harness limiting plate 4 .

[0041] See 6 and Figure 7, shown are the perspective view and the top view of the wire harness limiting plate 4 of the present application. Both ends of the wire harness limiting plate 4 are provided with first wire grooves 51 for wires to pass through. The two first wire grooves 51 cooperate for wire threading and wiring to limit the wires that are prone to swaying as the rotating disc 3 rotates, so that the bundled wires 7 are not easily swayed to pull the components connected to both ends thereof, can prevent the bundled wires 7 from colliding and interfering with other wires, and can also avoid the shortened service life of the wires caused by the bundled wires 7 scratching the base housing 2, making the child safety seat have better stability and safety. Among them, preferably, since the structure of the wire harness limiting plate 4 is plate-shaped or cover plate-shaped, the wire harness limiting plate 4 occupies less space in the base part 1. Further, it can also make the wires form an upper and lower layered structure in the base part 1 to increase the wire routing space in the base part 1.

[0042] The wire harness limiting plate 4 includes a wire routing part 41 and two wire bundling parts 42. The two wire bundling parts 42 are respectively located at both ends of the wire routing part 41.

The third wire groove 53 is located at the connection between the side convex part 43 and the wire routing part 41. Through the third wire groove 53, the available routing paths of the wires can be increased.

[0044] Preferably, in this embodiment, the path of the third wire groove 53 is arc-shaped, and the connection between the side convex part 43 and the wire routing part 41 is an arc-shaped structure. The third wire groove 53 with an arc-shaped path can increase the available insertion directions of the wires. [[ID=]))

[0045] Preferably, in this embodiment, the size of the first wiring groove 51 is larger than the size of the third wiring groove 53, and the size of the third wiring groove 53 is larger than the size of the second wiring groove 52. The first wiring groove 51 is located at both ends of the wire harness limiting plate 4, and the two ends of the wire harness limiting plate 4 correspond to the front end and the rear end of the base part 1. There are more components at the front end and the rear end of the base part 1, and the first wiring groove 51 can easily gather and limit more bundled wires 7; in addition, due to the structural limitation of the side protrusion 43, the size that can be opened of the third wiring groove 53 is larger than the second wiring groove 52, and the second wiring groove 52 and the third wiring groove 53 of different sizes have their own functions. Since the bundled wires 7 connected from the side of the wire harness limiting plate 4 are of different thicknesses, the second wiring groove 52 can gather and limit the thinner bundled wires 7, and the third wiring groove 53 can gather and limit the thicker bundled wires 7.

[0046] Preferably, in this embodiment, a wiring through-hole 44 is provided on the wiring portion 41, and the wiring through-hole 44 is located on the side of the wiring harness limiting plate 4 away from the rotating disk 3. The wiring through-hole 44 is used to match the connecting component below the rotating disk 3. Furthermore, not indicated in the figure, the wiring harness limiting plate 4 is also provided with a wiring protrusion matching the wiring through-hole 44, and the wiring protrusion is located on the outer side surface of the wiring harness limiting plate 4. The wiring through-hole 44 and the wiring protrusion are coaxially arranged, and the wiring through-hole 44 is partially inside the wiring protrusion; further, not indicated in the figure, a rotary switch is provided at the bottom of the rotating disk 3, and the rotary switch is connected to the component on the base shell 2 through the wiring through-hole 44, and cooperates with the wiring protrusion through the wiring through-hole 44 to make the rotary switch at the bottom of the rotating disk 3 connected to the component in the base portion 1, and the wiring protrusion can protect the connection between the rotary switch and the wire.

[0047] Preferably, in this embodiment, the countersunk hole 45 is located between the wiring portion 41 and the wiring bundle portion 42 .

[0048] See Figure 8 , shown is a left view of the wire harness limiting plate 4 of the present application, the fitting surface between the rotating disk 3 and the wire harness limiting plate 4 is arc-shaped, and the rotating disk 3 is matched with the inner convex arc surface of the rotating disk 3 by adopting the arc-shaped fitting surface.
