Description

Technical Field

[0001] This utility model belongs to the field of two-wheeled vehicle seat technology and relates to a seat opening support structure. Background Technology

[0002] Two-wheeled vehicles are a common mode of transportation in people's daily lives. Typically, a storage space is located at the bottom of the seat for everyday items such as raincoats, helmets, and gloves. Some two-wheeled vehicles also house the battery and other components at the bottom of the seat. Therefore, both during daily use and when repairing the two-wheeled vehicle, it is necessary to flip and open the seat for access.

[0003] However, existing two-wheeled vehicle seat cushions still have some shortcomings. When the seat cushion is opened, it usually remains in a natural state. When the seat cushion is touched or vibrated by external force, it is easy to flip and close, which may hit the rider or maintenance personnel, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the current technology by proposing a seat cushion opening support structure. The technical problem to be solved by this invention is: how to prevent the seat cushion from being easily closed when it is opened.

[0005] The objective of this utility model can be achieved through the following technical solution: a seat cushion opening support structure, including a base, a fixed pin on the inner side of the base, a swinging rocker arm on the pin, the bottom of the rocker arm being hinged to the pin, a fixed seat cushion on the top of the rocker arm, a torsion spring on the pin, a first abutment part and a second abutment part on the torsion spring, the first abutment part abutting against the bottom of the rocker arm, and the second abutment part abutting against the inner wall of the base.

[0006] In this design, the bottom of the rocker arm is hinged to a pin, allowing the rocker arm to rotate along the pin. The top of the rocker arm is fixedly connected to the seat cushion, allowing the seat cushion to flip along the pin. When the seat cushion is flipped open, the first abutment part on the torsion spring rests against the bottom of the rocker arm, while the second abutment part rests against the inner wall of the base below. Elastic potential energy supports the rocker arm, keeping the seat cushion open. By incorporating a torsion spring structure on the rocker arm, and using the first and second abutment parts on the torsion spring to support the rocker arm, the design prevents the seat cushion from easily closing when subjected to external force or vibration, avoiding pinching injuries and improving safety.

[0007] In the aforementioned seat cushion opening support structure, the torsion spring has upwardly extending first abutment portions at both ends, which abut against the bottom of the rocker arm. The middle section of the torsion spring has a downwardly extending second abutment portion, which abuts against the inner wall of the base. The two first abutment portions at both ends of the torsion spring better support the rocker arm and prevent the seat cushion from closing.

[0008] In the aforementioned seat cushion opening support structure, several torsion springs are provided on the pin. The first abutment portion of each torsion spring abuts against the bottom of the rocker arm, and the second abutment portion of each torsion spring abuts against the inner wall of the base. Multiple torsion spring structures can be provided on the pin to provide stronger support.

[0009] In the aforementioned seat cushion opening support structure, the base consists of a left aluminum seat and a right aluminum seat. Symmetrically arranged mounting posts are provided on the inner walls of the left and right aluminum seats, and both ends of the pin are inserted into the mounting posts. During installation, the pin is first inserted into one of the mounting posts, and then the rocker arm and torsion spring are inserted into the outside of the pin. When the left and right aluminum seats on both sides are joined together, the pin can be fixedly installed on the mounting posts.

[0010] In the aforementioned seat cushion opening support structure, the inner walls of the left and right aluminum seats are provided with inwardly extending connecting portions. These connecting portions have fixing holes, through which the left and right aluminum seats on both sides are fixedly connected. The connecting portions are used to connect the left and right aluminum seats on both sides, and the fixing holes securely connect the left and right aluminum seats.

[0011] In the aforementioned seat cushion opening support structure, the rocker arm has a bent portion that bends towards the front end, and the top of the bent portion has a mounting hole. The mounting hole is used to insert a bolt to fix the rocker arm to the seat cushion.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, a torsion spring structure is set on the swing arm. The first and second abutment parts on the torsion spring support the swing arm, preventing the seat cushion from easily closing when touched or vibrated by external force, avoiding pinching injuries, improving safety, and at the same time, the structure is simple and can improve the user experience.
