Description

Technical Field

[0001] This invention relates to a dragon boat land training device, belonging to the field of sports equipment technology, and particularly to the field of dragon boat sports training equipment technology. Background Technology Dragon boat racing is a highly team-oriented and competitive water sport that demands strong upper limb, trunk, and lower limb strength, rhythm coordination, and boat dynamic awareness from athletes. Due to limitations imposed by season, climate, and water conditions, athletes often have limited time and space for regular training on the water. Therefore, developing specialized dragon boat training equipment suitable for indoor or land-based environments is of great significance for improving training efficiency, ensuring sports safety, and promoting the sport.

[0002] Existing land-based dragon boat rowing machines mainly simulate paddling resistance in water through fixed supports and resistance devices. Their function focuses on improving athletes' specific strength and endurance, but they have significant shortcomings in the following aspects: 1. Lack of boat dynamic simulation: Existing equipment cannot reproduce the spatial displacement sensations such as undulation, acceleration and deceleration generated by the dragon boat as it moves across the water, resulting in a significant gap between training effects and the real competition environment.

[0003] 2. Insufficient training in rowing technique: Traditional rowing machines mostly focus only on the pull phase and lack trajectory guidance for the "entry, exit, and return" phases, making it difficult for athletes to develop complete and standard rowing technique in land training.

[0004] 3. Limited resistance modes: Existing equipment typically uses fixed resistance or simple magnetic / water resistance structures, which cannot flexibly adjust resistance characteristics according to training objectives, and also lacks realistic feedback on the relative motion of the paddle, the person, and the dragon boat.

[0005] 4. Low coordination between left and right rowers: The existing equipment is mainly for single rowing training, lacking training for left and right rowers to coordinate. It is difficult for athletes to develop tacit understanding and cooperation ability through training on land.

[0006] 5. Lack of specificity: The existing equipment lacks training equipment that is specific to different teams, which cannot meet the training needs of teams with different styles, resulting in poor training effects.

[0007] 6. Existing rowing machines are not durable and are cumbersome to maintain: Existing equipment mainly relies on built-in elastic ropes to achieve rebound, but the elastic ropes are not durable and need to be replaced frequently.

[0008] Therefore, there is an urgent need to find a dragon boat training device that can solve the above problems. Summary of the Invention

[0009] To address the above problems, the present invention provides a dragon boat land training device, comprising: The resistance box has a fixed circular track inside, and a semi-circular constraint track is set at the bottom of the box below the circular track. A horizontal track is set on the ground outside the resistance box, and the two sides of the first rigid rod are respectively slidably engaged with the circular track and the horizontal track; The cockpit is connected to the first rigid rod on one side via a telescopic component, and movably fitted to the semi-circular constraint track on the other side via a second rigid rod. The self-coiling drag engine includes a drag fan installed inside the drag box and a self-coiling damping mechanism installed on the drag fan. One end of the elastic rope is connected to the self-coiling damping mechanism, and the other end of the elastic rope is connected to the paddle plate. The elastic rope allows the paddle plate to be pulled to both sides of the cabin.

[0010] In some embodiments, the self-winding damping mechanism includes a first drive wheel coaxially arranged with the wind resistance fan, and a second drive wheel, a third drive wheel, and an elastic mechanism arranged around the first drive wheel. One end of the elastic rope is fixed to the elastic mechanism and is wound around the first drive wheel, the second drive wheel, and the third drive wheel in sequence. When the other end of the elastic rope is pulled, the elastic mechanism provides a rebound force to simulate resistance.

[0011] In some embodiments, the elastic mechanism includes a circular outer shell connected to one end of an elastic cord, and a wound spring is disposed inside the circular outer shell. One end of the spring is fixed to the central pivot of the circular outer shell, and the other end of the spring is fixed to the annular inner wall of the circular outer shell after being wound in a spiral shape. The elastic cord can drive the circular outer shell to rotate, and during the rotation, the elastic force generated by the spring being stretched provides a rebound force as damping.

[0012] In some embodiments, the outer periphery of the circular shell is provided with at least one tooth, and the resistance box is provided with a movable fastener. When the fastener is pressed down so that it engages with the tooth, the elastic rope cannot extend or retract, thus entering a fixed training state. When the fastener is released from the tooth, the circular shell returns to a free state, thus entering a resistance training state.

[0013] In some embodiments, the cockpit and the horizontal track are surrounded by a semi-enclosed baffle that connects to the resistance box, and the area enclosed by the semi-enclosed baffle and the resistance box constitutes a simulated training area.

[0014] In some embodiments, movable paddle track assemblies are provided on both sides of the semi-enclosed baffle. The paddle track assembly includes a movable platform and paddle tracks disposed on the movable platform, and the paddles can cooperate with the paddle tracks.

[0015] In some implementations, the paddle track is an irregular closed loop track that simulates a specific paddling trajectory.

[0016] In some embodiments, the paddleboard is connected to a universal joint on the paddleboard track via a thin rotating shaft.

[0017] In some embodiments, a telescopic member is connected to the front bottom of the cockpit, and an inverted triangular stabilizer is provided at the middle bottom of the cockpit, the stabilizer being connected to a second rigid rod.

[0018] In some embodiments, the surface of the drag box near the cockpit is provided with a paddle engagement groove.

[0019] The beneficial effects of this invention are: This invention utilizes a drag box, horizontal track, cabin, and self-rotating air resistance device to create equipment specifically designed for dragon boat training. It simulates the movement and undulations of a dragon boat during rowing, training athletes' spatial displacement awareness. The addition of a paddleboard track simulating dragon boat paddling techniques helps athletes quickly master the paddle trajectory for entry, pull, exit, and return. Furthermore, the paddle blades, connected to the air resistance fan, allow athletes to feel the relative movement between the paddle and the athlete. Fixed points can also be selected for more efficient paddling. Additionally, the two cabins on either side allow athletes to intuitively feel their teammates' rowing rhythm, fostering teamwork. The self-rotating air resistance device simplifies the mechanism of traditional rowing machines, significantly improving its durability. This invention can also perform motion capture for different teams, customizing exclusive tracks to significantly enhance training effectiveness.

[0020] Specifically, the present invention has the following advantages: 1. Enhance realism: By simulating the longitudinal and vertical displacement of the platform, athletes can effectively obtain a sense of spatial displacement and undulation similar to paddling on water when training on land, thereby cultivating a correct sense of time and rhythm.

[0021] 2. Complete technical training: The semi-circular constraint track can repeatedly limit the water exit trajectory of the blades, improve the stability and efficiency of individual movement practice, and also unify the consistency of technical movements among team members.

[0022] 3. Based on the different technical styles of each team, 3D motion software can be used to create the team's paddling technique style and generate corresponding paddling tracks to meet the personalized needs of different technical teams.

[0023] 4. Multi-mode resistance experience: By switching between fan-type resistance and fixed-point mode on the self-rolling wind resistance machine, athletes can not only feel the speed-related resistance of the relative motion between the paddle and the water, but also practice explosive movements with high resistance.

[0024] 5. Double-person training: It can be equipped with two cockpits, left and right, to meet the training needs of athletes in left and right oar positions, practice the rhythm of rowing in left and right oar positions, and improve team coordination.

[0025] 6. The self-winding wind resistance mechanism uses a spring as the rebound component, which significantly improves its durability and can meet the requirements of high-frequency paddle training. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, the terms "first" and "second" are used only to distinguish similar components / parts in different positions or with different characteristics, and have no other limiting meaning; "upper" refers to the direction in which each component is away from the ground, and "lower" refers to the direction in which each component is away from the ground.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] This invention provides a dragon boat land training device, which mainly includes a resistance box 1, a horizontal track 21, a cabin 3, and a self-rolling wind resistance machine, and has made significant innovations in dragon boat sports teaching, water sports technology simulation training, and paddling motion mechanics research.

[0040] In some embodiments, a circular track 22 is fixed inside the resistance box 1, and a semi-circular constraint track 23 is provided at the bottom of the circular track 22 below the circular track 22; in the examples of Figures 1-8, one end of the circular track 22 is fixed to the bottom inside the resistance box 1, and the other end extends out from the elongated hole on one side of the resistance box 1 and is in an upward-curved state.

[0041] In some embodiments, the horizontal track 21 is disposed on the ground outside the drag box 1, and the two sides of the first rigid rod 81 can be slidably engaged with the circular track 22 and the horizontal track 21 respectively by sliders; the direction of the horizontal track 21 is parallel to the orientation of the cabin 3.

[0042] In some implementations, the bottom of the cockpit 3 is connected to the first rigid rod 81 via a telescopic member 9 on one hand, and is movably engaged with the semi-circular constraint track 23 via a second rigid rod 82 on the other hand. In the examples of Figures 1-8, there are two cockpits 3, which are suitable for two-person training. The left and right cockpits allow athletes to more intuitively feel the rowing rhythm of their teammates and cultivate tacit understanding.

[0043] In some embodiments, a telescopic member 9 is connected to the bottom front end of the cockpit 3, and an inverted triangular stabilizer is provided at the bottom center of the cockpit 3, the stabilizer being connected to a second rigid rod 82. The telescopic member 9 is a sleeve structure, enabling self-expansion; the inverted triangular structure of the stabilizer enhances stability.

[0044] In some embodiments, the self-coiling drag engine includes a drag fan 4 disposed inside the drag box 1 and a self-coiling damping mechanism 5 disposed on the drag fan 4. One end of the elastic rope 7 is connected to the self-coiling damping mechanism 5, and the other end of the elastic rope 7 is connected to the paddle plate 6. The elastic rope 7 allows the paddle plate 6 to be pulled to both sides of the cabin 3.

[0045] In some embodiments, the surface of the drag box 1 near the cockpit 3 is provided with a paddle plate engaging slot. When not in use, the paddle plate 6 can be placed in the paddle plate engaging slot for storage, and when needed, it can be pulled out and pulled to both sides of the cockpit 3 by the elastic rope 7.

[0046] In some embodiments, the self-winding damping mechanism 5 includes a first drive wheel 51 coaxially arranged with the wind resistance fan 4, and a second drive wheel 52, a third drive wheel 53 and an elastic mechanism 54 arranged around the first drive wheel 51. One end of the elastic rope 7 is fixed to the elastic mechanism 54 and is wound around the first drive wheel 51, the second drive wheel 52 and the third drive wheel 53 in sequence. When the other end of the elastic rope 7 is pulled, the elastic mechanism 54 provides a rebound force to simulate resistance.

[0047] In the example in Figure 5, the second drive wheel 52 and the third drive wheel 53 are respectively arranged below the periphery of the first drive wheel 51 and above the right. The elastic mechanism 54 is located on the left side. The elastic rope 7 passes through the first drive wheel 51, is pulled back and then wound around the second drive wheel 52. After passing through the third drive wheel 53, it is sent out from the small hole on one side of the resistance box 1 and connected to the paddle plate 6.

[0048] In some embodiments, the elastic mechanism 54 includes a circular outer shell 542 connected to one end of the elastic rope 7. A wound spring 541 is disposed inside the circular outer shell 542. One end of the spring 541 is fixed to the central pivot 543 of the circular outer shell 542, and the other end of the spring 541 is fixed to the annular inner wall of the circular outer shell 542 after being spirally wound. The elastic rope 7 can drive the circular outer shell 542 to rotate. During the rotation, the elastic force generated by the spring 541 being stretched provides a rebound force as damping.

[0049] In some embodiments, the outer periphery of the circular outer shell 542 is provided with at least one tooth, and the resistance box 1 is provided with a movable fastener 55. When the fastener 55 is pressed down so that it engages with the tooth, the elastic rope 7 cannot extend or retract, thus entering a fixed training state. When the fastener 55 is released from the tooth, the circular outer shell 542 returns to a free state, thus entering a resistance training state.

[0050] In some embodiments, a semi-enclosed baffle 11 connecting the resistance box 1 is provided around the cockpit 3 and the horizontal track 21. The area enclosed by the semi-enclosed baffle 11 and the resistance box 1 constitutes a simulated training area. In the examples of Figures 1 and 2, steps can also be provided behind the cockpit 3. Considering that the cockpit 3 of the present invention is located at a certain height, it can facilitate the trainees to climb onto the cockpit 3. The steps can also be connected to the semi-enclosed baffle 11 and the resistance box 1 to form an integral unit.

[0051] In some embodiments, movable paddle track assemblies 10 are provided on both sides of the semi-enclosed baffle 11. The paddle track assembly 10 includes a movable platform and paddle tracks disposed on the movable platform, and the paddles 6 can cooperate with the paddle tracks.

[0052] In some embodiments, the movable platform is a support with casters, with a paddleboard track connected above it. As shown in Figures 1-2, the paddleboard track assembly 10 is moved to both sides of the resistance box 1 for standby when not in use. As shown in Figure 7, when specific paddleboard rowing trajectory training is required, the paddleboard 6 can have its head plate removed and its paddle shaft directly engaged with the paddleboard track. As shown in Figure 8, the paddleboard 6 can be connected to a universal joint on the paddleboard track via a thin pivot shaft, allowing the paddleboard 6 to run along the paddleboard track to assist in adjusting the trainee's movements.

[0053] In some implementations, the paddleboard track is an irregular closed loop track that simulates a specific paddling trajectory. The shape of the paddleboard track can be generated using a specific trajectory data model collected by a computer simulation system, as shown in Figure 7, which can complete a quasi-elliptical trajectory with a major axis of 2.5m and a minor axis of 20cm.

[0054] For specific training needs, the trainee sits inside the cabin 3, holding the paddle stick 6, which is connected to the thin rod supports on both sides, and moves back and forth along a fixed trajectory. Alternatively, different shaped paddle stick tracks can be selected and fitted to achieve different training objectives.

[0055] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
