[0031] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0032] An embodiment of the present application provides a kayak training device for allowing a user to perform kayak simulation training on land. The contents of the kayak simulation training include left-side paddling training, right-side paddling training, and left-right alternating paddling training.

[0033] Please refer to the attached Figure 1The kayak training device provided in an embodiment of the present application includes a first frame 10 and a carrying device. The carrying device is disposed on the first frame 10, and the kayak training device carries the user via the carrying device. The carrying device includes a carrying portion 21, a seat 22, and a footrest 23. The carrying portion 21 is disposed on the first frame 10, and the seat 22 and the footrest 23 are disposed on top of the carrying portion 21 and spaced apart along a first direction. When a user uses the kayak training device, the user's buttocks sit on the seat 22 and the feet step on the footrest 23. The carrying device is disposed so as to be reciprocatingly movable along the first direction, so that during kayak simulation training, the user's body can be reciprocated back and forth in the first direction via the carrying device, enabling the kayak training device to provide the user with a more realistic kayak simulation training scene, thereby improving the user's kayak sports experience and training effect.

[0034] The carrying device has an initial position and a moving position along the first direction. It is understood that the initial position of the carrying device may be the position of the carrying device immediately before the user begins kayak simulation training, and the moving position may be the position of the carrying device after moving a certain distance along the first direction from the initial position. There may be multiple moving positions arranged along the first direction. During the user's kayak simulation training, the farthest moving position reached by the carrying device each time it moves along the first direction may be the same or different.

[0035] The first direction may be, but is not limited to, the length direction of the first frame 10 to reduce the volume of the kayak trainer. Figure 1 As shown, the first direction is the length direction of the first rack 10, and the length direction of the first rack 10 is as shown in the attached Figure 1 As shown by arrow A.

[0036] A first movable structure is provided between the carrying device and the first frame 10, and the carrying device moves back and forth on the first frame 10 via the first movable structure. The first movable structure may be, but is not limited to, a roller 12 structure or a sliding structure. When the first movable structure is a roller 12 structure, the friction between the carrying device and the first frame 10 can be reduced, thereby increasing the service life of the trainer. Figure 1 The first frame 10 is provided with guide grooves 11 on both sides along the width direction, the bearing portion 21 is provided with two rows of rollers 12 and each row of rollers 12 includes a plurality of rollers 12 arranged at intervals along the length direction of the first frame 10, and the two rows of rollers 12 are respectively located in the two guide grooves 11 and move in the corresponding guide grooves 11.

[0037] Please refer to the attached Figure 2-3In some embodiments of the present application, the seat 22 is rotatable reciprocatingly along both a first rotational direction and a second rotational direction, the first rotational direction and the second rotational direction being opposite. The rotation axis of the seat 22 is parallel to the first direction, that is, the rotation axes of the first rotational direction and the second rotational direction are coaxial and parallel to the first direction.

[0038] The first rotation direction may correspond to the left rotation direction of the seat 22, and the second rotation direction may correspond to the right rotation direction of the seat 22. Figure 2 As shown, the first rotation direction is as shown in the attached Figure 2 As shown by the arrow B in the figure, the second rotation direction is as shown in the figure. Figure 2 As shown by arrow C in FIG. During kayaking training, when the user performs left-side paddling training, the seat 22 rotates in a first rotational direction driven by the user's body, causing the user's body to tilt to the left. When the user performs right-side paddling training, the seat 22 rotates in a second rotational direction driven by the user's body, causing the user's body to tilt to the right. After the left-side paddling training or the right-side paddling training is completed, the seat 22 returns to its original position, and the user's body also returns to its original position. It should be understood that the left and right sides in the left-side paddling training and the right-side paddling training described herein refer to the left and right sides of the user on the supporting device.

[0039] Among them, along the first rotation direction, the seat 22 has an initial position and a first rotation position; along the second rotation direction, the seat 22 has an initial position and a second rotation position. It can be understood that the initial position of the seat 22 is the position of the seat 22 when the user is about to perform kayak simulation training, the first rotation position is the position of the seat 22 after rotating a certain angle along the first rotation direction from the initial position, and the second rotation position is the position of the seat 22 after rotating a certain angle along the second rotation direction from the initial position. The initial position of the seat 22 in the first rotation direction and the initial position in the second rotation direction can be the same position. The seat 22 in the initial position can be, but is not limited to, set vertically, as shown in the attached figure. Figure 2 As shown. There may be multiple first and second rotational positions, each of which may be arranged along the first and second rotational directions, respectively. During kayak simulation training, the farthest first rotational position reached by the seat 22 each time it moves along the first rotational direction may be the same first rotational position or a different first rotational position, and the farthest second rotational position reached by the seat 22 each time it moves along the second rotational direction may be the same second rotational position or a different second rotational position.

[0040] In this embodiment, by arranging the seat 22 to be rotatable, the user's body can be adaptively tilted left and right with the paddling action, further improving the authenticity of the kayak simulation training scene provided by the kayak trainer, and further improving the user's kayak sports experience and training effect.

[0041] The seat 22 can be, but is not limited to, rotatably mounted on the supporting device via the first rotating shaft 224. Figure 2-3 The seat portion 22 includes a first base 221 and a seat plate 222. The seat plate 222 is disposed on top of the first base 221. Two mounting plates 223 are disposed at the bottom of the first base 221. Both mounting plates 223 are provided with first mounting holes 2231. The bearing portion 21 is provided with a mounting tube 211 located between the two first mounting holes 2231. A rotatable first rotating shaft 224 is mounted within the mounting tube 211. The two ends of the first rotating shaft 224 are respectively passed through the two first mounting holes 2231. Screws 225 are screwed onto both ends of the first rotating shaft 224 to secure the first rotating shaft 224 to the seat portion 22.

[0042] Please continue to refer to the attached Figure 1 In some embodiments of the present application, the kayak trainer further includes a first resistance device 30, which is connected to the seat 22 to apply a pulling force along the moving reset direction to the moving carrying device and to apply a pulling force along the rotational reset direction to the rotating seat 22.

[0043] It is understood that the movement reset direction refers to the direction in which the carrying device moves from the moved position to the initial position, which is also the opposite direction of the first direction. The rotation reset direction refers to the direction in which the seat portion 22 rotates from the first rotation position to the initial position after moving in the first rotation direction, which is also the opposite direction of the first rotation direction; or the direction in which the seat portion 22 rotates from the second rotation position to the initial position after moving in the second rotation direction, which is also the opposite direction of the second rotation direction.

[0044] During left-right alternating paddling training, when the user performs left-side paddling training, the supporting device is driven by the user to move in the first direction, and the seat 22 is simultaneously driven to the left by the user. When the user performs right-side paddling training, the supporting device is driven by the user to move in the first direction, and the seat 22 is simultaneously driven to the right by the user. Specifically, when the supporting device moves in the first direction, the first resistance device 30 applies a pulling force to the supporting device in the movement reset direction through the seat 22. This pulling force not only increases the resistance of the supporting device in the first direction to simulate the forward water resistance of the kayak, further improving the realism of the kayak simulation training scenario provided by the kayak training device, but also drives the supporting device to move in the movement reset direction after the supporting device stops moving in the first direction, thereby completing the reset of the supporting device. When the seat 22 rotates to the left or right, the first resistance device 30 applies a pulling force to the seat 22 along the rotational reset direction. This pulling force not only increases the rotational resistance of the seat 22 along the first rotational direction or the second rotational direction to simulate the water resistance of the kayak roll, further improving the authenticity of the kayak simulation training scene provided by the kayak trainer, but also can drive the supporting device to rotate along the rotational reset direction after the seat 22 stops rotating in the first rotational direction or the second rotational direction to complete the reset of the seat 22.

[0045] In this embodiment, by configuring the above-mentioned first resistance device 30, not only can resistance be applied to the simultaneously moving supporting device and seat 22, but the supporting device and seat 22 can also be driven to automatically move along their respective reset directions, further improving the user's kayaking experience and training effect.

[0046] The tension applied by the first resistance device 30 can be a constant tension or a non-constant tension. Constant tension means that the tension applied by the first resistance device 30 to the load-bearing device is constant during the reciprocating movement of the load-bearing device, while constant tension means that the tension applied by the first resistance device 30 to the load-bearing device varies during the reciprocating movement of the load-bearing device. When the tension applied by the first resistance device 30 is a constant tension, the resistance provided by the first resistance device 30 to the load-bearing device and the seat 22 more closely matches the water resistance of the kayak in water, further enhancing the user's kayaking experience and training effectiveness.

[0047] In some embodiments of the present application, the magnitude of the pulling force applied by the first resistance device 30 can be adjusted, so that the kayak training device can be suitable for different user groups, thereby improving the practicality of the kayak training device.

[0048] It is understood that adjusting the pulling force refers to the user adjusting the current resistance provided by the first resistance device 30 before the kayak simulation training. During the movement of the carrying device and the seat 22, the pulling force applied by the first resistance device 30 is its inherent pulling force.

[0049] Please continue to refer to the attached Figure 1 In some embodiments of the present application, the first resistance device 30 includes a second frame 31, a counterweight portion, a flexible cable 32 and a pulley portion. The first resistance device 30 provides a constant pulling force to the load-bearing device and the seat 22 through the deadweight of the counterweight portion. The counterweight portion includes a mounting member and a plurality of counterweights, and the mounting member is used to carry the counterweights. The plurality of counterweights can be of the same counterweight specification or different counterweight specifications. The plurality of counterweights can be selectively mounted on the mounting member, that is, the counterweights can be mounted on the mounting member or not mounted on the mounting member at the user's option to adjust the number or counterweight specifications of the counterweights mounted on the mounting member, thereby adjusting the pulling force provided by the first resistance device 30. The mounting member is reciprocally movably arranged along the height direction of the second frame 31. The pulley portion is arranged on the second frame 31, and one end of the flexible cable 32 is connected to the mounting member and the other end passes around the pulley portion and is connected to the seat 22. The sheave portion includes a first sheave 33 located upstream of the connection position between the seat 22 and the flexible cable 32 in the first direction. That is, the connection positions between the first sheave 33, the seat 22, and the flexible cable 32 are arranged along the first direction.

[0050] When the load-bearing device moves in the first direction, the counterweight portion moves upward under the drive of the flexible cable 32. After the load-bearing device stops moving in the first direction, the counterweight portion moves downward under its own weight and drives the load-bearing device to move in the movement reset direction via the flexible cable 32. When the seat 22 rotates in the first rotational direction or the second rotational direction, the counterweight portion moves upward under the drive of the flexible cable 32. After the seat 22 stops rotating in the first rotational direction or the second rotational direction, the counterweight portion moves downward under its own weight and drives the seat 22 to rotate in the rotation reset direction via the flexible cable 32.

[0051] Please refer to the attached Figure 1 The first resistance device 30 can be, but is not limited to, arranged on the upstream side of the first frame 10 along the first direction, that is, the second frame 31 and the first frame 10 are arranged along the first direction, which not only helps to simplify the structure of the first resistance device 30, but also helps to reduce the width of the kayak trainer.

[0052] The second rack 31 is connected to the first rack 10 or not. When the second rack 31 is connected to the first rack 10, the connection between the two can be a non-detachable fixed connection such as welding or a detachable fixed connection such as screwing. Figure 1The second frame 31 is screwed to the first frame 10 so that the two can be disassembled and assembled, which helps to reduce the packaging and transportation costs of the kayak trainer.

[0053] Please refer to the attached Figure 1 The mounting member may be, but is not limited to, a mounting rod 35, and the counterweight may be, but is not limited to, a counterweight disc, which is sleeved on the mounting rod 35. Of course, in other embodiments, the counterweight may be a counterweight plate, and a plurality of counterweight plates are stacked along the height direction of the second frame 31, with insertion holes provided on the peripheral side surfaces of the counterweight plates. The mounting member may be a mounting rod 35, which may be inserted into the insertion hole of any counterweight plate to drive the current counterweight plate and the counterweight plates stacked above the current counterweight plate to move up and down.

[0054] In order to improve the stability of the counterweight, a sleeve 36 can be provided on the mounting piece and a first guide rod 37 can be provided on the second frame 31. The sleeve 36 is movably mounted on the first guide rod 37. The first guide rod 37 can be vertically arranged or tilted relative to the vertical direction.

[0055] The rope pulley portion may be only the first rope pulley 33, or may include several rope pulleys, which is not specifically limited in this application. Figure 1 The sheave portion includes a first sheave 33 and a second sheave 34. The second sheave 34 is located on the side of the first sheave 33 close to the counterweight portion and above the first sheave 33. One end of the flexible rope 32 is connected to the sleeve 36 and the other end passes around the second sheave 34 and the first sheave 33 in sequence and is connected to the seat 22.

[0056] It is understood that the first resistance device 30 is not limited to the embodiment provided in this embodiment. For example, in other embodiments, the first resistance device 30 may include a second frame 31 and an elastic structure, with both ends of the elastic structure respectively connected to the second frame 31 and the seat 22 to provide a non-constant pulling force to the moving seat 22. The elastic structure may be, but is not limited to, an elastic rope or a spring.

[0057] Please continue to refer to the attached Figure 2-3In some embodiments of the present application, the support device includes a support portion 21, a seat portion 22, and a pedal portion 23 disposed on top of the support portion 21. The seat portion 22 is provided with a first anti-rotation mating surface 2261 and a second anti-rotation mating surface 2262, and the support portion 21 is provided with a first anti-rotation surface 2121 and a second anti-rotation surface 2122. The first anti-rotation surface 2121 is located downstream of the first anti-rotation mating surface 2261 in a first rotational direction. The first anti-rotation surface 2121 and the first anti-rotation mating surface 2261 can engage with each other in the first rotational direction to prevent the seat portion 22 from rotating in the first rotational direction. The second anti-rotation surface 2122 is located downstream of the second anti-rotation mating surface 2262 in a second rotational direction. The second anti-rotation surface 2122 and the second anti-rotation mating surface 2262 can engage with each other in the second rotational direction to prevent the seat portion 22 from rotating in the first rotational direction.

[0058] The plurality of first rotational positions include a first extreme rotational position. At the first extreme rotational position, the first anti-rotation surface 2121 and the first anti-rotation mating surface 2261 abut against each other in the first rotational direction to form a anti-rotation fit, thereby stopping the seat 22 from rotating in the first rotational direction. The first anti-rotation surface 2121 and the first anti-rotation mating surface 2261 do not contact each other in the initial position and at other first rotational positions of the seat 22. The plurality of second rotational positions include a second extreme rotational position. At the second extreme rotational position, the second anti-rotation surface 2122 and the second anti-rotation mating surface 2262 abut against each other in the second rotational direction to form a anti-rotation fit, thereby stopping the seat 22 from rotating in the second rotational direction. The second anti-rotation surface 2122 and the second anti-rotation mating surface 2262 do not contact each other in the initial position and at other second rotational positions of the seat 22.

[0059] In this embodiment, the seat 22 and the bearing portion 21 are anti-rotationally engaged through an anti-rotation surface and an anti-rotation mating surface, which increases the anti-rotation mating area of ​​the seat 22 and the bearing portion 21 and extends the service life of the seat 22 and the bearing portion 21.

[0060] Please refer to the attached Figure 2-3 The mounting plate 223 is provided with two anti-rotation fitting blocks 226, the first anti-rotation fitting surface 2261 and the second anti-rotation fitting surface 2262 are respectively located on the bottom surfaces of the two anti-rotation fitting blocks 226, and the top of the bearing part 21 is provided with four anti-rotation blocks 212 arranged one-to-one corresponding to the four anti-rotation fitting blocks 226.

[0065] Please refer to the attached Figure 7-8 In some embodiments of the present application, an elastic limiting structure is provided between the first frame 10 and the load-bearing portion 21. The elastic limiting structure includes two limiting members and two limiting mating members. The two limiting members are provided on one of the first frame 10 and the load-bearing portion 21, and the two limiting mating members are provided on the other of the first frame 10 and the load-bearing portion 21. The two limiting members are respectively located on both sides of the two limiting mating members along the first direction, wherein adjacent limiting members and limiting mating members are elastically limited and matched. By providing the above-mentioned elastic limiting structure, the reciprocating movement range of the load-bearing device can be limited, and hard contact between the load-bearing device and the first frame 10 can be avoided when the two are in limited cooperation. This not only extends the service life of the limiting structure, but also improves the user experience of the kayak trainer.

[0066] Specifically, the two limiting members are a first limiting member 214 and a second limiting member 215, and the two limiting fitting members are a first limiting fitting member 13 and a second limiting fitting member 14. The first limiting member 214, the first limiting fitting member 13, the second limiting fitting member 14 and the second limiting member 215 are arranged in sequence along the first direction. The first limiting member 214 and the first limiting fitting member 13 can be elastically limited and fitted, and the second limiting member 215 and the second limiting fitting member 14 can be elastically limited and fitted. It can be understood that the process of elastic limited fitting between the limiting member and the limiting fitting member is as follows: the limiting member and the limiting fitting member first elastically abut against each other to gradually reduce the moving speed of the load-bearing device, and when the speed of the load-bearing device drops to 0, the limiting member and the limiting fitting member are in a limited and fitted state.

[0067] Among them, preferably, when the carrying device is in the initial position, the second limiting member 215 and the second limiting fitting member 14 are in a limiting fitting state, and the multiple moving positions of the carrying device include an extreme moving position. When the carrying device is in the extreme moving position, the first limiting member 214 and the first limiting fitting member 13 are in a limiting fitting state.

[0068] Among them, at least one of the first limiting member 214 and the first limiting fitting member 13 is an elastic limiting member, and at least one of the first limiting member 214 and the first limiting fitting member 13 is also an elastic limiting member. The elastic limiting member can be but is not limited to an elastic cylinder, an elastic limiting block, etc. Preferably, please refer to the attached Figure 4 Two limiting members are arranged on the bearing portion 21, and two limiting matching members are arranged on the first frame 10, and the limiting matching members are elastic cylinders.

[0069] Please continue to refer to the attached Figure 1 In some embodiments of the present application, the kayak training device further includes a paddle shaft 40, a second rotating shaft 41, a first rope pulley 42, a second rope pulley 43, a first elastic cord 44, a second elastic cord 45, and a second resistance device. The second rotating shaft 41 is disposed on the first frame 10, and the first rope pulley 42 and the second rope pulley 43 are both disposed on the second rotating shaft 41. One end of the first elastic cord 44 is connected to one end of the paddle shaft 40, and the other end of the first elastic cord 44 passes through the first rope pulley 42 and is connected to the first frame 10. One end of the second elastic cord 45 is connected to the other end of the paddle shaft 40, and the other end of the second elastic cord 45 passes through the second rope pulley 43 and is connected to the first frame 10. When a user performs paddling training using the paddle shaft 40, the first elastic cord 44 and the second elastic cord 45 drive the second rotating shaft 41 to rotate in a third rotational direction. The second resistance device is connected to the second rotating shaft 41 to apply rotational resistance to the second rotating shaft 41 when it rotates in the third rotational direction.

[0070] The resistance type of the second resistance device may be, but is not limited to, wind resistance, electromagnetic resistance, or the like. Preferably, the second resistance device comprises a motor and a transmission structure, with the motor shaft and the second rotating shaft 41 being connected via the transmission structure. When the second rotating shaft 41 rotates in the third rotational direction, the motor shaft, driven by the transmission structure, rotates. During this process, the shaft generates electromagnetic resistance under electromagnetic action, which acts as rotational resistance on the second rotating shaft 41.
