Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a power supply connection structure for a child seat. Background Art

[0002] Child safety seats are a common device that can accommodate infants and young children of different ages. They are designed mainly for the safety of children in vehicles. They can restrain children from dangerous behaviors in the vehicle during driving and protect children from injuries in the event of accidents such as sudden vehicle collisions. For ease of use and operation, some safety seats are also equipped with a backrest rotation adjustment mechanism. However, when the backrest is rotated and adjusted, the backrest and the base will move relative to each other. If the backrest circuit is directly connected to the base circuit through the turntable in order to simplify the circuit structure, the circuit harness will be twisted off after the backrest rotates several times.

The power base is passed through and fixed to the axis of the turntable, and the power plug is fixed on the seat base. The power plug and the power base are plug-connected to realize circuit conduction, and the two are coaxially rotated.

[0005] In the above scheme: the power base is in the shape of an axis, with a thread and an anti-rotation plane on its outer circumference, and a limiting step at its bottom end. The axis of the turntable is provided with a through hole matching the power base, and the power base passes through the through hole from bottom to top, and is locked on the turntable through the limiting step and the nut. The limiting step is pressed against the lower side of the turntable, and the nut is pressed against the upper side of the turntable, so that the power base is locked and fixed, with a simple structure and easy installation.

[0006] In the above scheme: the power plug includes a plug body and a plug shell, the seat base is provided with a mounting column, the plug shell is fixed to the mounting column by bolts, the top of the plug shell is open and a mounting groove is provided therein, the plug body is inserted into the mounting groove from top to bottom, and an anti-rotation structure is provided between the plug body and the plug shell, the structure is simple and easy to install.

[0007] In the above scheme: the bottom surface of the power base is provided with a power slot, the plug body includes a plug-in portion for plugging into the power slot and a mounting portion for assembling with the plug housing, the plug-in portion is a cylindrical body, the mounting portion is a polygonal columnar body, the mounting slot matches the mounting portion, and the two cooperate to form an anti-rotation structure. The plug-in portion is on the top, the mounting portion is on the bottom, the plug-in portion and the power slot form a rotational fit, and the mounting portion and the mounting slot form a non-rotational fit.

[0008] In the above scheme: the limiting step of the power base extends into the top opening of the plug shell, and an avoidance structure for avoiding the limiting step is provided in the top opening of the plug shell. The avoidance structure is funnel-shaped to prevent the plug shell from contacting the power base and interfering with its rotation.

[0009] In the above scheme: the upper end of the power base is connected to a wiring harness for connecting to the electrical components on the backrest, and the lower end of the plug body is connected to a wiring harness that passes downward through the plug shell and is connected to the base bus to achieve conduction between the base circuit and the backrest circuit.

[0010] The beneficial effects of the utility model are as follows: the power base is fixed on the turntable and moves with the turntable, so when the backrest fixed above the turntable rotates, the power line connected to the power base and the backrest do not move relative to each other, and will not be twisted or broken; the power plug is fixed to the seat base, and the seat base limits its rotation. When the power plug and the power socket are connected, the power plug will not rotate with the rotation of the power socket, and the power line connected to the power plug and the seat base do not move relative to each other, and will not be twisted or broken. In short, the utility model realizes that the backrest circuit passes through the turntable and is directly connected to the base circuit, simplifying the circuit structure.
