Description

Technical Field

[0001] This application relates to the technical field of electric vehicles, and in particular to a rear seat for an electric vehicle. Background Technology

[0002] The seat is one of the key components of an electric vehicle. It is mainly used to support the weight of the rider and passengers, and to mitigate and dampen the impact and vibration transmitted from the vehicle body, creating a smooth and comfortable riding experience for the rider and passengers.

[0003] Electric vehicles often have storage space under the seat for placing the battery or other items. Usually, the vehicle needs to be turned off and opened with the same key to retrieve (or place) the items.

[0004] Currently, the seat cushion of an electric scooter is rotatably connected to the frame near the front of the scooter. When the user retrieves (or places) an item, they need to rotate the seat cushion to press it against the front of the scooter. The rotation angle of the seat cushion is relatively large, which can easily damage the dashboard at the front of the scooter. Furthermore, the seat cushion relies on gravity to press against the front of the scooter, and external forces can cause the seat cushion to rotate, potentially causing injury to the user who is retrieving (or placing) an item. Utility Model Content

[0005] To improve the ease of opening the seat cushion and enhance the safety of electric vehicles, this application provides a rear seat for electric vehicles.

[0006] The technical solution for the rear seat of an electric vehicle provided in this application is as follows:

[0007] An electric vehicle rear seat includes a seat cushion body, a fixed base, a first hinge rod, a second hinge rod, and a resetting member. The fixed base is connected to the vehicle frame. One end of the first hinge rod is hinged to the fixed base, and the hinge axis between the first hinge rod and the fixed base is horizontal. The other end of the first hinge rod is hinged to the side of the seat cushion body away from the front of the electric vehicle, and the hinge axis between the first hinge rod and the seat cushion body is parallel to the hinge axis between the first hinge rod and the fixed base. One end of the second hinge rod is hinged to the fixed base, and the hinge axis between the second hinge rod and the fixed base is parallel to but does not coincide with the hinge axis between the first hinge rod and the fixed base. The other end of the second hinge rod is hinged to the seat cushion body, and the hinge axis between the second hinge rod and the seat cushion body is parallel to the hinge axis between the second hinge rod and the fixed base. The resetting member is connected between the first hinge rod and the second hinge rod, and the resetting member causes the first hinge rod and the second hinge rod to tend to move closer to each other.

[0008] By adopting the above technical solution, the fixed seat is connected to the frame, one end of the first hinge rod is hinged to the fixed seat, and the other end of the first hinge rod is hinged to the side of the seat body away from the front of the vehicle, so that the seat body rotates away from the front of the electric vehicle, reducing the possibility of the seat body hitting the dashboard at the front of the vehicle.

[0018] By adopting the above technical solution, the hinge seat is connected to the base plate, and the first hinge rod and the second hinge rod are hinged to the hinge seat, which facilitates the replacement of the base plate or the hinge seat as needed, thereby reducing the maintenance cost of electric vehicles.

[0019] Preferably, the lower end of the base plate is provided with a mounting groove for the hinge seat to be embedded in, and the hinge seat is provided with a fixing hole for the bolt to pass through and be threaded to the base plate.

[0020] By adopting the above technical solution, the mounting base provides initial positioning for the hinge base, which facilitates the subsequent fixed connection between the hinge base and the base plate, thereby improving the assembly efficiency of the seat cushion body.

[0021] Preferably, the end of the base plate away from the hinge seat has a groove for inserting a finger.

[0022] By adopting the above technical solution, a groove is provided at the end of the base plate away from the hinge seat. This groove is used for inserting fingers, making it easier for users to apply force when opening the seat cushion, thereby improving the convenience and comfort of opening the seat cushion body.
