Slide is used in skiing training

Technical Field

The invention relates to the technical field of ski training equipment.

Background

At present, during skiing training, a beginner and a skier are not greatly different, for the skiller, the control of skiing speed can be realized through self operation technology, however, for the beginner, the operation technology in the skiing process is not skillful, particularly, when the beginner slides on a slope, the problem that the speed is too fast easily occurs only by using the existing skier, and the beginner is difficult to effectively control the speed and is easy to fall down.

To the too fast dangerous problem of initiation easily of speed during the skiing training, there are some skis at present and can stretch out the brake nail downwards when the speed is too fast, insert in the snow to brake the ski by force and stop, in order to reach the protection purpose to beginner. However, the method of forcibly braking once overspeed is caused is not suitable for beginners to learn the speed reduction technique effectively, and is not suitable for beginners to grasp the skiing technique completely, and the method of forcibly braking as soon as overspeed is caused easily causes trainers to fall down and hurt; in addition, when stopping, the snow that hangs on the brake nail can increase gradually, leads to the effect that stops in the braking process can worsen gradually, therefore stops the effect and is difficult to continuously guarantee, uses the reliability not enough.

As shown in fig. 4-5, a brake plate 13 is fixed on the front side of the rotating shaft 8; the brake plate 13 is correspondingly positioned on the front side of the mounting through hole 6; the lower side of the front part of the brake plate 13 is of a convex arc structure; a B cam 14 for driving a brake plate 13 to move is sleeved and fixed on the supporting shaft 10; the B cam 14 corresponds to the brake plates 13 one by one; the orientation of the B cam 14 is opposite to that of the a cam 12; when the far end of the cam 14B pushes the brake plate 13 to move downwards to the lowest position, the near end of the cam 12A blocks the upper end of the speed reducing plate 7, and the lower side of the front end of the brake plate 13 is attached to the lower side of the front end of the mounting through hole 6; an alarm 15 is fixedly arranged on the upper side of the sliding plate main body 1; the alarm 15 is connected with the control circuit; a direct-connected switch 16 of the speed reducing motor 9 is fixedly arranged on the upper side of the sliding plate main body 1.

Compare with the tradition as long as slide the hypervelocity just stop the mode of stopping, what adopt among this technical scheme is speed limit, accuse fast mode, through will slide speed control within safe speed, realize the protection effect to the training person, this kind of mode can not cause frequent brake to stop, has both avoided the compulsory brake to stop and has leaded to the training person to fall down injured's problem easily, has avoided frequent brake to stop again and has caused adverse effect's problem to the skiing training.

As shown in fig. 6, the GPS positioning sensor 4 can detect the moving distance of the skateboard body 1 in real time by means of satellite positioning while taxiing, the inclination angle sensor 5 can detect the inclination angle of the skateboard body 1 in real time, the sliding speed of the skateboard body 1 can be determined in real time through the processing of the control circuit, once the sliding speed reaches a set limit value, the control circuit controls the speed reduction motor 9 to operate, the distal end of the cam 12A rotates downwards, the rear part of the speed reduction plate 7 is pressed downwards to be scraped with the snow, and the speed reduction effect on the skateboard body 1 is realized, as shown in figures 2-3, when the speed is reduced to the safe range, the control circuit controls the speed reducing motor 9 to operate, the cam A12 rotates back, the pressing of the speed reducing plate 7 is relieved, through this process, the sliding speed of the skateboard body 1 can be controlled within a certain safety range (which can be set according to the training level of the trainee).

In the above process, the tilt sensor 5 is provided because the distance data detected by the GPS positioning sensor 4 cannot be directly converted into the speed data, and because the GPS positioning sensor 4 detects the horizontal moving distance, and the moving distance when the skateboard is sliding on a slope is not equal to the horizontal moving distance, the tilt sensor 5 needs to be combined with the tilt angle to perform conversion to determine the real moving distance of the skateboard body 1, so as to accurately determine the speed of the skateboard body 1, and avoid errors caused by terrain problems.

Besides the speed limiting means, an emergency braking and stopping means is further arranged in the technical scheme to further protect beginners and avoid danger caused by the fact that the speed cannot be reduced within the specified time. Once the sliding speed cannot be controlled within a safe range within a specified time (a time range is set according to training requirements) due to factors such as excessive shake of the slope during sliding, forced acceleration of a beginner and the like, the control circuit controls the speed reducing motor 9 to operate, the far end of the B cam 14 rotates downwards, the brake plate 13 is pressed downwards to be sunk into snow, the near end of the A cam 12 blocks the speed reducing plate 7, the brake plate 13 is positioned, the brake plate 13 is sunk into the snow to realize the brake action on the sliding plate main body 1, and the front side of the installation through opening 6 is blocked by the brake plate 13 at the moment, so that the snow is prevented from overflowing from the installation through opening 6, as shown in figures 4-5; in addition, because the anterior downside of brake block 13 is convex arc structure, consequently can play the guide effect to snow in the braking process, avoid snow to last to gather on brake block 13 to make the braking effect can last to guarantee, stop the reliability height (in the same way, the continuous gathering of snow also can be avoided to the air brake 7 front side).

In the above process, in order to avoid interference caused by the respective actions of the a cam 12 and the B cam 14, the two cams are arranged in opposite directions on the supporting shaft 10 (i.e., opposite directions of the distal ends of the two cams), and the speed reduction motor 9 can use a stepping motor, and the rotation angle of the output end thereof is controlled by a control circuit.

In the technical scheme, an alarm 15 is also arranged, and when the speed is over-speed, the control circuit can control the alarm 15 to give an alarm to remind a trainer of taking a speed reduction action and remind other personnel in a field of attention; the direct-connected switch 16 of the speed reducing motor 9 installed on the sliding plate main body 1 can control the speed reducing motor 9 to continuously operate, so that the brake plate 13 and the speed reducing plate 7 shake, snow adhered to the brake plate can be shaken down, and the effect of convenient cleaning is achieved.

It should be noted that in this technical solution, the speed reduction plate 7 is for playing the role of speed reduction and speed limitation, and the brake plate 13 is for braking, so the depth of the speed reduction plate 7 pressed into the snow is set to be smaller than the depth of the brake plate 13 pressed. In addition, the double-plate type sliding plate is adopted, and the two sliding plates are consistent in structure, so that the other sliding plate is not marked in the figure, and the description is not repeated in the application document.
