On June 17, 2026, information from the State Intellectual Property Office showed that a patent titled “Shock-absorbing sealing structure, cab and loader” applied by Guangxi Liugong Yuanxiang Technology Co., Ltd. and Guangxi Liugong Machinery Co., Ltd. was authorized. The authorization announcement number is CN224363380U, and the authorization announcement date is June 16, 2026.
The patent application number is CN202521428814.5, the application publication date is June 16, 2026, and the application date is July 9, 2025.
The patent summary shows that this shock-absorbing sealing structure belongs to the field of loader technology.
It includes a first shock-absorbing component, a second shock-absorbing component and a noise reduction component.
The first shock-absorbing component is connected between the sole plate and the vehicle frame, the second shock-absorbing component is connected between the mounting plate and the vehicle frame, and the noise reduction component is sealingly arranged between the sole plate and the vehicle frame.
The noise reduction component includes a first noise reduction component and a second noise reduction component. The first noise reduction component is provided at the flange of the foot plate. The second noise reduction component is attached to the vehicle frame, and the first noise reduction component and the second noise reduction component are in contact with each other.
This kind of shock-absorbing sealing structure can significantly improve the shock-absorbing effect of the cab by arranging the first shock-absorbing component and the second shock-absorbing component, thereby effectively reducing the noise in the cab.
At the same time, the first noise reduction part and the second noise reduction part provided between the frame and the foot plate form two noise reductions, which further reduces the noise in the cab, improves the driving experience, and has low improvement cost.
Tianyancha data shows that Guangxi Liugong Yuanxiang Technology Co., Ltd. was established on February 27, 2023. The industry it belongs to is the technology promotion and application service industry, and the scale of the enterprise is large.
