[0009] An unlocking and fixing mechanism is provided in the mounting slot and connected to the mounting block. The unlocking and fixing mechanism is connected to the connecting part to lock or unlock the button.

[0010] A reset mechanism is connected to the button to drive the button to reset.

[0011] In this solution, a button is set up. When the button is pressed, the button's connecting part unlocks from the unlocking and fixing mechanism. The button then rotates under the guidance of the reset mechanism, thereby unlocking the device. At the same time, the cooperation between the contact part and the limit part precisely controls the rotation stroke of the button to prevent damage from overtravel and to prepare for the next operation. After the button is opened, garbage bags or food with soup can be hung up, keeping the vehicle clean and convenient to use.

[0012] Preferably, the button is provided with a through hole, and a pin is provided in the through hole, the pin being connected to the inner walls of both sides of the mounting groove.

[0013] In this design, the pin connection method facilitates assembly, ensures smooth rotation, provides reliable support, effectively withstands the torque during button operation, and guarantees long-term stability.

[0014] Preferably, the connecting part is a buckle, which is integrally formed with the button and located on the side of the button near the mounting block. The unlocking and fixing mechanism is a PUSH lock, and the buckle is engaged in the PUSH lock.

[0015] In this design, the snap-fit ​​and push button are integrally molded, which simplifies the number of parts and improves the connection strength; the snap-fit ​​engages with the push lock to form a clear and stable locking state; the transmission is direct and efficient with a fast response; and the snap-fit ​​structure between the snap-fit ​​and the push lock facilitates assembly.

[0019] In this design, the contact between the limiting block and the first inclined surface provides stable limiting support; the angle of the first inclined surface determines the maximum rotation angle of the button, allowing for flexible design.

[0020] As a further preferred embodiment, the reset mechanism is a torsion spring, which is sleeved on the pin, and the other end of the torsion spring is connected to the mounting block.

[0021] In this solution, the torsion spring provides a constant and directional reset torque, ensuring that the button can accurately and quickly return to its initial position when unlocked; the torsion spring has a mature structure, good fatigue resistance, and long service life.

[0022] Preferably, the housing is provided with a fixing groove, and a damper is disposed in the fixing groove.

[0023] In this design, the damper makes the button rotation smoother and more stable, reduces the impact force when the torsion spring and the button itself return to their original position, helps protect related parts, and improves the overall durability of the mechanism; slowing down the movement helps avoid slight vibrations or secondary contact that may be caused by rapid rebound.

[0024] As a further preferred embodiment, the damper is provided with a first tooth, and the button is provided with a second tooth on one side, the first tooth and the second tooth meshing together.

[0025] In this solution, the gear meshing method directly and without slippage transmits the rotation angle and speed of the button to the damper rotor, resulting in an immediate and linear damping effect. By designing the tooth size and the internal damping coefficient of the damper, the rotation speed of the button can be precisely controlled.

[0026] Preferably, a protruding knob is provided on one side of the button, which makes it convenient for the user to press the button.

[0027] In this design, the protruding knob makes it easier for fingers to access and apply force, especially suitable for operation while wearing gloves or in confined spaces; the protruding knob serves as a visual and tactile marker, allowing users to quickly locate the operating position.
