Lumbar support mechanism, seat cushion device and two-wheeled vehicle
This invention relates to a lumbar support mechanism, a seat device, and a two-wheeled vehicle. The lumbar support mechanism includes a lifting assembly, a lifting seat, and a support member. The lifting seat is mounted on the movable end of the lifting assembly, and the support member is mounted on the lifting seat and can elastically float relative to the lifting seat within at least one degree of freedom. Since the preset direction is inclined to the longitudinal direction of the seat body, the lifting assembly drives the lifting seat to move along the preset direction, simultaneously adjusting the height and distance of the support member to accommodate riders of different body types, significantly improving the adaptability of lumbar support. Furthermore, because the support member can elastically float relative to the lifting seat within at least one degree of freedom, it can also adaptively conform to the rider's lumbar contour and riding posture, avoiding localized pressure concentration or unsupported areas. Therefore, the aforementioned lumbar support mechanism can achieve excellent support, effectively relieving lumbar fatigue during riding and significantly improving riding comfort.

Computer aided design system for agricultural machine box white model support
PendingCN122655479AEliminate local excessive deformationEliminate cracks
The present application belongs to the field of computer-aided design, and particularly to a computer-aided design system for supporting a white model of an agricultural machine box. The system constructs a three-dimensional geometric model of the white model of the agricultural machine box and extracts the elastic modulus and yield limit parameters; establishes a discrete element model of the sand and a kinematics equation of the vibration table to simulate the sand filling and vibrating process, and obtains the distribution of the dynamic fluid-structure coupling pressure field of the white model surface; takes the dynamic pressure field distribution as the external load boundary condition, takes the maximum deformation of the white model being less than the yield critical value as the constraint, and takes the minimum volume of the support structure as the target to solve the density distribution of the support material; in combination with the support cross-section size requirement of the white model casting process, the density distribution is subjected to threshold extraction and geometric reconstruction to generate a non-uniform support structure that is fitted to the white model surface and adapts to the vibration pressure. The support distribution is matched with the dynamic pressure field, the local deformation and rupture of the white model are eliminated, the support redundancy is avoided, and the structural stability is improved.
