Description

Technical Field

[0001] The invention belongs to the field of mechanical engineering, and in particular relates to an adaptively adjustable engineering machinery seat and an adjustment method. Background Art

[0002] Seat vibration reduction is an important issue involving vehicle ride comfort and passenger health. There are various ways to reduce seat vibration in the automotive industry. In addition to optimizing the filling materials inside the seat, seat vibration reduction is also performed through a seat adjustment device. The seat adjustment device usually has multiple elastic vibration reduction parts for passive vibration reduction or multiple moving parts that are linked to each other to achieve active vibration reduction. The former passive vibration reduction does not require external energy and has relatively low cost, but the vibration reduction effect may be subject to certain limitations. The latter actively reduces vibration according to the vibration conditions. Although the vibration reduction effect is good, it cannot be applied to engineering vehicles.

[0003] like Figure 1 As shown, the existing active vibration reduction adjustment device uses an electromagnetic actuator to perform active vibration reduction, and is linked to the electromagnetic actuator through a vertically arranged pneumatic actuator, so that the size in the Z-axis direction is increased, causing the overall structure of the seat to be relatively high. Although the vibration in the Z-axis direction can be eliminated as much as possible on smooth roads, the internal space of the cab of engineering vehicles is limited and engineering vehicles are often used in harsh working conditions. The impact force of the vehicle on the seat adjustment device is large and in different directions; if the adjustment device only achieves single Z-axis vibration reduction, the vibration reduction effect is poor and it is also easy to cause poor stability of the seat adjustment device.

[0004] Finally, the seat adjustment device will easily lead to structural failure due to long-term vehicle bumps. As a result, the existing adjustment devices on construction machinery have problems such as low precision, poor stability and short service life and cannot be effectively promoted. The drivers of construction vehicles must stay in their seats for a long time during their careers. Therefore, the optimization of seat vibration reduction for construction vehicles is not only an important factor in improving their productivity, but also a necessary means to prevent health damage to drivers.
