Description

Technical Field

[0001] The utility model relates to the technical field of child seats, in particular to a folding device for a child seat of an electric vehicle. Background Art

[0002] Battery cars are also called "electric cars". They are pure electric vehicles powered by batteries and driven by electric motors. In recent years, they have been widely used in my country.

[0003] The usage rate of existing two-wheeled electric vehicles is getting higher and higher. In the process of using electric vehicles, in order to facilitate children to ride, corresponding child seats are often installed on electric vehicles. In the actual use of existing child seats, in order to save space when not in use, the seats are often designed to be foldable. However, most of the existing folding structures use tension springs to pull the rotating seats so that they can be positioned after rotation. However, the tension spring mechanism is prone to damage and the cost is relatively high. Therefore, we propose a folding device for electric vehicle child seats. Utility Model Content

[0004] The utility model aims to provide a folding device for a child seat of an electric vehicle, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a folding device for a child seat of an electric vehicle, comprising a base, a fixing column is fixed on the top of the base, a handle is fixed on the top of the fixing column, a connecting frame is fixed on one side of the middle of the fixing column, a rotating block is provided in the inner cavity of the connecting frame, a seat cushion is fixedly connected to the outer end of the rotating block, arc-shaped slides are provided on both side walls of the connecting frame, positioning pins are penetrated on both sides of the side walls of the rotating block, both ends of the positioning pins are respectively penetrated through the arc-shaped slides on both sides, a first card groove is provided at one end of the arc-shaped slide, and a second card groove is provided at the other end of the arc-shaped slide.

[0006] By adopting the above technical solution, when the seat cushion needs to be rotated for folding, the seat cushion is lifted to rotate the rotating block, and at the same time, the two positioning pins are made to slide in the arc-shaped slide, so that one of the positioning pins slides into the second slot, so that the seat cushion is limited after being stored to ensure stability. When putting down the seat cushion, the other positioning pin is slid into the first slot to achieve limiting. Compared with the previous tension spring mechanism for folding, the technical solution has a simple structure, is convenient and fast to operate, saves labor, and effectively reduces the production cost of the device.

[0007] As a preferred embodiment of the present utility model, a reinforcing rib is fixedly connected between the tail end of the fixing column and the connection between the base.

[0008] By adopting the above technical solution and setting the reinforcing ribs, the connection strength between the fixing column and the base can be improved.

[0009] As a preferred embodiment of the present invention, three evenly distributed strip holes are provided on both sides of the top of the base.

[0010] By adopting the above technical solution and setting the strip holes, it is convenient to install and fix the device as a whole, and the position can be adjusted during installation, thereby improving the use effect.

[0011] As a preferred embodiment of the present invention, outer walls at both ends of the handle are fixedly sleeved with matching rubber sleeves.

[0012] By adopting the above technical solution and the provision of the rubber sleeve, relative sliding between the hand and the handle can be avoided when holding the handle.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The technical solution of the present application is a folding device for a child seat of an electric vehicle. Two positioning pins are arranged on the outer wall of a rotating block. The positions of the two positioning pins can be changed by rotating the seat cushion and the rotating block, so that the seat cushion is stuck in the first slot or the second slot, thereby realizing the folding operation of the seat cushion. Compared with the previous folding by a tension spring mechanism, the technical solution has a simple structure, is convenient and fast to operate, and saves labor, while effectively reducing the production cost of the device.
