[0011] Furthermore, the backrest body includes a copper plate base and a sponge layer, the second mounting seat is fixedly connected to the rear of the copper plate base, and the sponge layer is fixedly connected to the front of the copper plate base.

[0012] Furthermore, the bracket is an adjustable bracket with adjustable length.

[0013] The utility model has beneficial effects:

[0014] The utility model provides an adjustable backrest for an electric vehicle, which can be adjusted according to the situation. When only the driver is driving the electric vehicle, the backrest body can be adjusted to the rear of the driver. At this time, the adjustable bracket is placed horizontally, the front end of the adjustable bracket is limited by the second mounting seat, and the rear end is limited by the first mounting seat, so the support is stable. When there are passengers sitting on the back seat of the electric vehicle, the backrest body can be adjusted to the rear of the passenger. At this time, the adjustable bracket is placed vertically, the lower end of the adjustable bracket is limited by the first mounting seat, the backrest body is limited by the adjustable bracket and will not rotate, so the support is stable.
