Description

Technical Field

[0001] The present invention relates to the technical field of sports training equipment, and in particular to a snowboarding intelligent training device and a training method. Background Art

[0002] With the successful holding of various sports games, skiing has gradually shed the image of "aristocratic sport", and the stimulation and body-building functions of the sport itself have made it a sport deeply loved by the general public. With the surge in the number of skiers, people's technical requirements have also increased, from the initial entry to the current advanced stage. At the same time, with the country's advocacy of the development of ice and snow sports, Chinese athletes have also achieved certain results in the arena. Therefore, ski enthusiasts have higher requirements for improving their technical level.

[0003] However, due to the short snow season in my country and the limited coverage of ski resorts, many ski enthusiasts do not have enough time to participate in the sport of snowboarding. Secondly, skiing itself is difficult and the speed is fast. It is difficult for people to overcome their fear and it is difficult for the human body to break through the constraints of its own balance system. At present, there is no training equipment that can fully simulate skiing movements, which cannot meet the training needs of amateurs and professional athletes. The above factors make it necessary to learn skiing and become a high-level skier through long-term practice and training, spending a lot of time and money, and the success rate is extremely low.

[0004] The above information disclosed in the background technology section is only used to enhance the understanding of the background technology of the technology described in this article. Therefore, the background technology may contain certain information that does not form the prior art known in this country for those skilled in the art. Summary of the invention

[0027] During the 1 / 4-1 / 2 process, the internal program of the single-chip computer controls the speed of the running gears in the first drive unit and the second drive unit respectively, forming a speed difference, thereby causing the direction of the snowboard to shift, thereby simulating the stage of turning in the sliding track. During this process, the trainer is subjected to a certain centripetal force through the upper handle and the sliding sleeve, and the training board can rotate along the bottom rod by ±30°, gradually realizing technical movements such as falling, standing on the edge, applying pressure, turning the hips, applying pressure, etc. After this stage is over;

The machine rotates, thereby making the telescopic slide rail coordinated and synchronized with the front and rear tracks; by setting a slope simulation mechanism, the height of the first drive unit and the second drive unit is adjusted by the hydraulic jacking member, so that the slope is shaped at a certain angle along the movement direction of the training board, and the slope can be adjusted according to the training needs, thereby simulating different slope scenes of skiing; and a balance mechanism is set to assist the trainee to maintain balance, so that the participant can use more physical strength to control his body posture; the protective net around the frame and the protective pad at the bottom can provide all-round protection, on the one hand, to protect the personal safety of the trainee in the event of an emergency, and on the other hand, to prevent irrelevant personnel from entering the training area, so that the safety of the trainees is guaranteed.

[0046] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0048] There are 11 snowboarding events in total. my country won 2 medals in the snowboarding event in the competition. These two medals achieved a breakthrough in my country's "zero" gold medal in the snowboarding event. my country's overall strength in the snowboarding event is still far behind other traditional powers. Therefore, how to improve my country's competitive strength in snowboarding, narrow the gap with the snowboarding powers, and avoid the excellent results achieved being just a flash in the pan is a realistic problem that needs to be focused on at this stage. As snowboarding has gradually become the most popular winter sport. With the increase in the number of participants, people's requirements for its technology have also increased. After the basic introduction, skiing enthusiasts generally need to choose their own advanced practice branches, such as flat flowers, park, and slalom, which is generally called carving. All three branches are dangerous. "Slalom" is mainly to press the center of gravity onto the edges on both sides of the snowboard by leaning left and right, and to use the board shape designed by the snowboard and the gliding technology of entering and exiting the corners due to gravity acceleration. Compared with the other two techniques, the "slalom" technique requires a particularly high balance ability in speed and edge, which causes many skiing enthusiasts or professional athletes to make mistakes in their high, medium and low sliding postures when dealing with different snow conditions, and even suffer from injuries. At present, there is no special training equipment for skiing. This project is a training device that simulates actual snow for skiing enthusiasts and professional athletes. It aims to effectively help participants overcome objective factors based on the various coordination problems caused by speed and balance during actual practice. With the help of electronic power assistance, participants can control the balance and body posture of the snowboard with their whole body. While meeting this condition, the protective weight-bearing devices on the top and sides provide participants with special muscle training to achieve better sports performance.

[0049] In view of this, the present invention provides a snowboard intelligent training device for special training of "turn" technical movements. Figure 1 to Figure 5 The present invention is described in detail.

[0050] A snowboard intelligent training device, see Figure 1 ,include:

[0051] The frame 1 is a metal gantry frame structure with dimensions of 7m in length, 3m in width and 2m in height, including a bottom frame and gantry frames on both sides;

[0052] The walking mechanism includes a first driving unit 2 and a second driving unit 3 which are arranged on both sides of the bottom frame.

[0053] The first driving unit 2 and the second driving unit 3 are both arranged along the length direction of the bottom frame;

[0054] The training board 4, both ends of the training board 4 are connected to the first driving unit 2 and the second driving unit 3 respectively, and the first driving unit 2 and the second driving unit 3 are provided with motor driving structures, which can independently control the movement of both ends of the training board 4 along the length direction of the frame 1;

[0055] The telescopic mechanism is arranged between the first drive unit 2 and the second drive unit 3, and is used to control the movement direction of the first drive unit 2 or the second drive unit 3, and to limit the distance between the first drive unit 2 and the second drive unit 3 so as to adapt to the inclination of the training board 4.

[0056] The first drive unit 2 and the second drive unit 3 are respectively connected to the two ends of the training board 4, and the first drive unit 2 and the second drive unit 3 are used to independently control the movement speed and direction of the two ends of the training board 4, so that the training board 4 is tilted while moving forward. The training requires the inclination to be set between 0-80°, and the distance between the drive units on both sides is adjusted by the telescopic mechanism to be consistent with the inclination of the training board 4, so that the drive units on both sides of the frame 1 and the training board 4 move in a coordinated and synchronous manner; through the above structure, a speed difference is formed at both ends of the training board 4 while the training board 4 moves in one direction, thereby simulating the trajectory of the trainee in the actual sliding process and various training movements such as rotation.

[0057] In a specific embodiment, see Figure 2 The first drive unit 2 and the second drive unit 3 have the same structure, including a shell 5, the shell 5 is made of metal, a hollow chamber is arranged in the shell 5, strip slide grooves 6 are opened on both sides of the shell 5, and an annular track 7 is installed in the shell 5. The annular track 7 adopts two 4:08B single-row tracks with a length of 10m. The two ends of the annular track 7 are meshed with a tensioning gear 8. The central axis of the tensioning gear 8 is rotatably connected to the side wall of the shell 5, and the central axis is fixedly connected to a power source. A traveling gear 9 is meshed and installed in the middle of the annular chain. The gear type is white 4:13 single-axis with an inner diameter of 100 mm, and the central axis of the traveling gear 9 is connected to the training board 4. Through the above, the driving source provides power, and the power is transmitted to the tensioning gear 8 through the central shaft. The tensioning gear 8 is meshed and installed at both ends of the annular track 7. The rotation of the tensioning gear 8 drives the annular track 7 to rotate around the tensioning gear 8. A traveling gear 9 is meshed and installed in the middle of the annular track 7. On the one hand, the annular track 7 can provide power for the traveling gear 9, and on the other hand, it also limits the travel trajectory of the traveling gear 9. Under the action of the annular track 7, the traveling gear 9 reciprocates along the direction of the strip slide 6 to realize the power transmission between the driving source and the training board 4.

[0058] In a further embodiment, see Figure 2, the driving source is a rotating motor 10 fixedly mounted on the side of the housing 5, the rotating motor 10 is a stepping motor, and the output end of the rotating motor 10 is fixedly connected to the central axis of the tensioning gear 8. Through the above, the rotating motor 10 can be directly fixedly mounted on the housing 5, and the connection method between the output shaft of the rotating motor 10 and the tensioning gear 8 can be adopted, the central hole of the tensioning gear 8 is provided with a card slot, and the output shaft of the rotating motor 10 is correspondingly provided with a card block, and the output shaft is correspondingly inserted into the central hole, so that the card block and the card slot are engaged, thereby completing the power transmission from the motor to the tensioning gear 8, with a simple structure and high stability.

[0059] In another preferred embodiment, see Figure 1 , and also includes a slope simulation mechanism, including a hydraulic jacking member 11 arranged at the bottom of both ends of the shell 5 in the first drive unit 2 and the second drive unit 3, the hydraulic jacking member 11 specifically includes: a jacking plate 13 fixedly connected to the bottom of the shell 5 and a hydraulic cylinder 12 fixedly arranged on the ground, the output end of the hydraulic cylinder 12 is connected to both ends of the jacking plate 13, and the hydraulic jacking member 11 is used to adjust the height of one end of the shell 5 so that the forward direction of the ski board forms an inclined plane with an angle of 0-30 degrees with the horizontal plane. Based on the above, the height of both ends of the first drive unit 2 and the second drive unit 3 is adjusted by the hydraulic jacking member 11, so that the slope of the training board 4 along the movement direction is formed at a certain angle, and the slope can also be adjusted according to training needs, thereby simulating different slope scenes of skiing.

[0060] In a specific embodiment, see Figure 3 , 4 , the training board 4 comprises:

[0061] The plate body 14 is 170 cm long and 30 cm wide, and a shoe body fastening sleeve 15 is provided on the surface of the plate body 14;

[0062] The rod body 16 is 150 cm long, and the plate body 14 is rotatably connected to the rod body 16. The two ends of the rod body 16 are connected to the central axis of the traveling gear 9 through a universal shaft connection mechanism 17. The central axis of the traveling gear 9 is rotatably connected to the input shaft of the universal shaft connection mechanism 17 through a rotary bearing (not shown in the figure). A limit slider 18 is fixedly provided on the input shaft of the universal shaft connection mechanism 17. The limit slider 18 is cooperatively connected to the strip slide groove 6, and a rotation limit structure is fixedly connected to the rod body 16.

[0063] Based on the above, since the traveling gear 9 itself rotates while moving forward, the training board 4 used for training does need to remain horizontal while moving forward. In addition, the central axis is fixedly connected to the traveling gear 9, and its direction is always perpendicular to the forward direction. However, the training board 4 will deflect due to the speed difference at both ends, so the connection structure between the rod body 16 and the central axis cannot be a fixed connection structure. Based on the above, it is necessary to set a movable connection structure between the rod body 16 at the bottom of the training board 4 and the central axis of the traveling gear 9, so that the central axis can move forward and rotate at the same time, and the board body 14 moves forward with the central axis, but it always remains in a horizontal direction and only flips at a certain angle in the horizontal direction; in an optional implementation manner. The movable connection structure adopts a universal joint connection mechanism 17, and a rotating bearing is provided at the connection between the central axis of the traveling gear 9 and the universal joint connection mechanism 17. The rotating bearing prevents the rod body 16 from rotating with the rotation of the central axis, and a limiting slider 18 is fixedly provided on the input shaft of the universal joint connection mechanism 17. The limiting slider 18 is connected with the strip slide 6 to prevent the rod body 16 from rotating during the forward movement, thereby achieving the forward movement and rotation of the central axis of the traveling gear 9 while keeping the rod body 16 at the bottom of the training board 4 in a horizontal movement state without rotating; the board body 14 moves with the rod body 16 and can rotate around the rod body 16, but under the limitation of the rotating limiting structure, it can only flip at a small angle. Through this ingenious power transmission structure, the problem of how to use the motor as a power source to drive the training board 4 to perform horizontal displacement is overcome.

[0064] In a further embodiment, see Figure 4 The rotation limiting structure includes a V-shaped limiting plate 19 and a torsion spring 20 fixedly arranged on the rod body 16. The opening angle of the V-shaped limiting plate 19 faces the plate body 14, and the opening angle is set to 90-150 degrees, which is used to limit the rotation angle of the plate body 14 on the rod body 16. The two ends of the torsion spring 20 are respectively in contact with the plate body 14. Through the above, in order to prevent the training board 4 from turning 360° around the rod body 16 to ensure the safety performance of the training, and in order to make it convenient for the user to stand on the plate body 14 in the initial state, it is necessary to limit the rotation of the plate body 14 on the rod body 16. The V-shaped limiting plate 19 and the torsion spring 20 can double limit the plate body 14, so that it can only rotate within the range of ±30° on the horizontal plane, and through the elastic force of the torsion spring 20, the initial state of the plate body 14 is always kept horizontal, so as to solve the above three technical problems.

[0065] In a specific embodiment, see Figure 5 , the telescopic mechanism comprises:

[0066] The telescopic slide rail 21 includes an outer rail and an inner rail. The outer rail is sleeved on the inner rail and is slidably connected to the inner rail. The end of the outer rail is fixedly connected to the housing 5 of the first drive unit 2, and the end of the inner rail is fixedly connected to the housing 5 of the second drive unit 3. In this embodiment, the shapes of the outer rail and the inner rail are not limited as long as they can achieve relative sliding.

[0067] The telescopic gear rack mechanism comprises a telescopic motor 22, a telescopic gear 23 and a rack 24, wherein the telescopic motor 22 is fixedly mounted on the housing 5 of the second drive unit 3, the telescopic gear 23 is fixedly connected to the output end of the telescopic motor 22, and the rack 24 is arranged along the width direction of the frame 1, one end of which is fixedly connected to the housing 5 of the first drive unit 2 on the opposite side of the telescopic motor 22, and is meshed with the telescopic gear 23. Specifically, the telescopic motor 22 can be directly fixedly mounted on the housing 5, and the connection mode between the output shaft of the telescopic motor 22 and the telescopic gear 23 can be fixed by clamping, the center hole of the telescopic gear 23 is provided with a clamping groove, and a clamping block is correspondingly provided on the output shaft of the telescopic motor 22, and the output shaft is correspondingly inserted into the center hole, so that the clamping block and the clamping groove are clamped and matched, thereby completing the power transmission from the telescopic motor 22 to the telescopic gear 23, and the telescopic gear 23 rotates around the output shaft of the motor, driving the rack 24 to move along the length direction of the telescopic slide rail 21, solving the problem of the constant distance between the two drive units when the length of the training board 4 is fixed but the direction changes.

[0068] In another preferred embodiment, see Figure 1 , and also includes a balancing mechanism, which includes a balancing rod 25 arranged on the top of the frame 1 along the length direction of the frame 1, the height of the balancing rod 25 is set to 2m, and a sliding sleeve 26 is slidably connected to the balancing rod 25, and the sliding sleeve 26 is provided with a connecting hole for connecting a safety rope, and a handle 27 for the trainee to hold with both hands is slidably connected to the balancing rod 25, and an emergency stop button 28 is provided on the handle 27, which is remotely connected to the switch of the whole machine. In order to prevent accidental touch, a protective cover is provided above the button, and limit blocks 29 are also fixedly provided at both ends of the balancing rod 25, and the distance between the limit blocks 29 is consistent with the length of the strip slide 6. Based on the above, the balancing device mainly provides auxiliary functions for the trainee. It is connected to the safety harness worn by the trainee through a safety rope to prevent the trainee from losing the center of gravity during the training process, thereby improving passive safety. At the same time, the trainee can actively control his or her posture during the forward movement by holding the handle 27 with both hands, and can also improve the trainee's control over body balance. When a fault occurs, the trainee can control the device to stop running through the emergency stop button 28 on the handle 27, thereby improving active safety.

[0069] In another preferred embodiment, see Figure 1, and also includes a safety protection mechanism, including a protection net 30 arranged around the frame 1, and a protection pad at the bottom of the frame 1 (not shown). Based on the above, the protection net 30 around the frame 1 is used to protect the trainee on the one hand, and prevent unrelated personnel from entering the training area and causing safety hazards on the other hand; when an emergency occurs, such as when the trainee falls to the ground during the preparation process, the protection pad at the bottom of the frame 1 can protect the trainee's life safety.

[0070] Another aspect of the present invention further provides a training method based on the above-mentioned snowboard intelligent training device, the method comprising the following steps:

[0071] In the first 1 / 4 of the process, the traveling gear 9 in the annular crawler 7 is driven to rotate by the rotating motor 10, driving the ski board to move forward along the strip chute 6;

[0072] During the 1 / 4-1 / 2 process, the internal program of the single chip microcomputer controls the rotation speed of the travel gear 9 in the first drive unit 2 and the second drive unit 3 respectively, forming a rotation speed difference, thereby causing the direction of the snowboard to shift, thereby simulating the turning stage in the sliding track. During this process, the trainer is subjected to a certain centripetal force through the upper handle 27 and the sliding sleeve 26, and the training board 4 can rotate along the bottom rod body 16 by ±30°, gradually realizing technical movements such as falling, standing on the edge, applying pressure, turning the hips, applying pressure, etc. After this stage is over;

[0073] From 1 / 2 to 3 / 4 of the process, the speed of the rear track increases, the speed of the front track decreases, and the speed of the front track running gear 9 gradually decreases from the maximum speed to slightly faster than the rear track running gear 9, thereby simulating the actual curve exiting stage during the sliding process.

[0074] In the last 1 / 4 of the process, the rotation speeds of the front and rear rail gears gradually balance, and the telescopic distance of the rear rail returns to its original position.

[0075] Based on the above, compared with the current training devices, more emphasis is placed on automation and intelligence; the motor drive enables the snowboard to simulate the sliding trajectory more realistically than the existing equipment when in motion, and the left and right annular tracks 7 work together to achieve technical movements such as turning the hips and changing the line of sight in the large loop of the snowboard.

[0076] Advantages of the intelligent training device and method of the present invention:

[0077] This product emphasizes scientific, intelligent and automated, and adopts a one-button start method, which is more convenient to operate. It has low requirements for the working environment, more stable operation, and better protection effect, so that trainees can better master the relevant technologies. The setting of the balance device can ensure that the trainees maintain the balance and stability of the center of gravity during training. The speed difference is generated by the motor, so that the snowboard can simulate the actual sliding trajectory when snowing, which is not available in the current research. At present, other designs use more one-way sliding methods, and users cannot achieve technical actions such as turning hips and changing vision in the big loop of the snowboard. It can allow advanced snowboard enthusiasts and professional athletes to have better and more targeted training equipment.

[0078] Nowadays, skiing has become a sport for parents, socializing, and exercising. However, due to the short snow season, many people do not have enough time to improve their skills. Some even choose to go to Xinjiang or even go abroad, and the cost is self-evident. This design can not only meet the purpose of snowboarding enthusiasts to advance, but also replace dry snow machines in teaching in major clubs and become the first choice!

[0079] It also has excellent promotion prospects and market economic benefits:

[0080] Promotion prospects. Although the ski tourism industry has developed rapidly in recent years, it is still far from the "period of princes rising up and heroes competing for hegemony". The development of snowboarding in my country is in its infancy, with little cultural accumulation and strong plasticity in project development. With the increase in people's attention, it will undoubtedly bring more opportunities for the development of the project. my country's ski resort construction and ski tourism consumer products are far from enough. The ski industry is in the growth and development stage, with huge market potential, and it is far from forming a so-called customer source competition situation between provinces. In such a situation of low scale and level, the fundamental task is development. Since the introduction of snowboarding, national teams for snowboarding U-shaped field skills, parallel giant slalom, obstacle pursuit, slope obstacle skills, and big jump have been established. By continuously introducing relevant knowledge, technology, and competitions, the snowboarding culture has been internalized, and a unique snowboarding culture has been formed in combination with the current development status of the project. What we have to do now is how to form a joint force, promote the development of the skiing industry in practice, and develop the skiing customer source market as soon as possible. The research and development and promotion of this product will definitely play a mainstay role in the development of snowboarding.
