These cushions effectively mitigate the impact of closing the side door, protecting the upper glass 33 from damage. They also enhance the sealing of the side door and prevent external noise and dust from entering the cab.

[0035] The rebound mechanism 4 includes a gas spring 41. One end of the gas spring 41 is fixedly connected to the frame body 31, and the other end is connected to the cab frame 1. The gas spring 41 achieves smooth opening and closing of the side door by adjusting the internal air pressure. When the side door is opened, the gas spring 41 provides auxiliary force, which reduces the burden on the operator when opening the side door, making the operation easier and smoother. When the side door is closed, the gas spring 41 presses the side door to the cab frame 1 through its reaction force, thereby working together with the sealing airbag 5 to further compress the sealing airbag 5 to ensure effective sealing of the cab and prevent outside air, noise and dust from entering the interior of the cab. The design of the gas spring 41 takes into account the overall structural strength of the cab and the frequency of use of the side door. Its material is usually durable and high-strength metal material, which can maintain good working condition during long-term use.

[0036] This design not only improves the ease of operation of the side doors, but also enhances their durability and sealing, ensuring that a comfortable and safe operating environment can be maintained inside the cab even under complex working conditions.

[0037] A cable tie 8 is also connected between the frame body 31 and the cab frame 1. The cable tie 8 is made of high-strength, corrosion-resistant materials, such as stainless steel or weather-resistant synthetic fibers, to ensure long-term stability in harsh environments. The cable tie 8 is used to further strengthen the connection between the frame body 31 and the cab frame 1. Especially when the side door assembly 3 is frequently opened and closed or subjected to external force impact, the cable tie 8 can effectively prevent the relative displacement between the side door and the cab frame, thereby maintaining the stability and sealing of the side door. The cable tie 8 has a simple design structure and is easy to install. It is usually fixed to the frame body 31 and the cab frame 1 by buckles or bolts. It has good tensile strength and anti-fatigue properties, and can maintain a reliable connection effect during long-term use. The use of this cable tie not only enhances the connection strength between the side door and the cab frame, but also provides additional safety protection for the entire cab, avoiding safety hazards caused by loose side doors.

[0038] A panel 9 is mounted on the frame body 31 of the side door assembly 3. This panel 9 is made of high-strength materials, such as steel or aluminum alloy, to ensure sufficient strength and durability. Panel 9 is secured to the frame body 31 by screws or welding, further reinforcing the side door structure. Hinges are mounted on panel 9, connecting the side door upper glass 33. These hinges are typically made of stainless steel or other corrosion-resistant metals to ensure they are not easily damaged during long-term use. The hinges allow the side door upper glass 33 to open and close stably relative to the panel 9. The hinges are well-designed, ensuring smooth rotation and maintaining a secure lock when the side door is closed.

[0039] Furthermore, panel 9 is designed for ease of maintenance.
