Description

Skiing simulation training device

Technical Field

The utility model relates to the technical field of skiing equipment, in particular to a skiing simulation trainer.

Background

Skiing is one of the most popular sports, and a typical skiing exercise uses two skis (skis), called double plates, which are two feet separated, each standing on a ski, the body naturally facing forward, the movement of the ski including "three linear movements" and "three axial rotations", as described later.

The displacement of the snowboard body in the "three linear directions" refers to the movement of the snowboard in the three linear directions, one of which is the movement in the "vertical" direction (movement along the Z-axis direction) of downward movement and upward movement, for example, the movement of the snowboard body in which the snowboard slides on the terrain with varying height, i.e., the movement of the snowboard body in the vertical direction (direction perpendicular to the ground surface or horizontal plane) is generated along with the terrain. The displacement in the "vertical" direction is a critical interlock with respect to the increase or decrease in speed. Secondly, the movement in the "lateral" direction (movement along the X-axis direction) of the left and right translations takes an actual skiing action as an example, and unless the skiing is straight facing the mountain Gu Zhixia, the skiing must follow the continuous movement in the lateral direction, and the skiing slides in the "lateral" direction in a circular arc path manner to increase the resistance of the skiing and the snow surface, and the linkage is to reduce the speed and provide a force for changing the direction, and meanwhile, the control and release of the resistance are critical to the speed between skiers and the skiing. Thirdly, the movement in the 'longitudinal' direction (movement along the Y-axis direction) of the forward movement and the backward movement is continuously carried out forward during sliding, and the snowboard body obviously senses the change of the forward longitudinal movement.

When the snowboard moves on the snow surface, three axial rotations of the spin axes are presented, which together form six rotational vectors. Firstly, the center of the snowboard is taken transversely as the axis: the front-back rotation, the front-back rotation and the front-back rotation (rotation around the X axis in the front and back directions) are performed. And secondly, taking the vertical direction of the center of the snowboard as the axis, turning left on the left horizontal plane and turning right on the right horizontal plane (turning left and right around the Z axis by taking the Z axis as the axis). Thirdly, the snowboard is taken as an axle center in the longitudinal direction and is rotated left and upward on the left vertical surface and rotated right and downward on the right vertical surface (rotated left and right around the Y axis by taking the Y axis as the axle center).

The known skiing simulators, either as sports training devices or in combination with Virtual Reality (VR) technology as entertainment devices, provide the user with a device as close as possible to a real skiing experience, basically by means of mechanical structures or in combination with electromechanical technology, under conditions of limited space occupation. In many of the known ski simulators, most have only lateral movement and do not provide a simulation of longitudinal movement. For example, published chinese patent application publication No. CN111675097 proposes a skiing simulation platform capable of realizing four main elements of inclination of the skateboard, overall lateral movement, opening and closing between the two skateboards, and angle between the two skateboards for restoring the skiing experience. Chinese patent application number CN213252914U, five degrees of freedom virtual reality skiing simulator, includes: the skiing device comprises a shell base, wherein a transverse sliding rail is fixed on the shell base, a transverse moving base is connected to the transverse sliding rail in a sliding manner, two skiing turnover devices are arranged on the transverse moving base, and a skiing carrying platform is connected with a front-back moving sliding rail, but can move slightly back and forth, so that the experience of forward sliding and turning during skiing cannot be truly simulated basically.
