Description

Technical Field

[0001] The invention relates to the technical field of training auxiliary equipment, in particular to a kayak resistance device. Background Art

[0002] In the field of canoeing training, efficient training equipment is crucial for athletes to improve their competitive level. Traditional canoeing training mainly relies on actual rowing training in natural waters or artificial rowing tracks. However, this training method has many limitations. On the one hand, it is greatly affected by natural factors such as weather and water conditions. For example, in bad weather, such as heavy rain and strong winds, training cannot be carried out normally, and differences in water flow speed and water quality in different waters will also interfere with the consistency evaluation of training effects. On the other hand, when training in actual waters, it is difficult to accurately control the training resistance conditions, and it is impossible to make targeted resistance adjustments according to the individual needs and training stages of athletes, which is not conducive to athletes systematically and scientifically improving rowing techniques and physical fitness.

[0003] In order to solve the above problems, kayak resistance devices came into being. Early kayak resistance devices mainly used simple mechanical structures, such as springs, rubber bands, etc. to provide resistance. Although this type of resistance device can simulate the resistance of rowing in a non-aquatic environment to a certain extent, it has many defects. The resistance characteristics provided by springs or rubber bands are relatively simple and cannot truly simulate the complex and changeable resistance of kayaks in water, such as the change in resistance at different paddling speeds. At the same time, these simple mechanical structure resistance devices perform poorly in terms of stability and durability, and are prone to failure.

[0004] To this end, the present invention proposes a kayak resistance device, which utilizes the interaction between water flow and a resistance cover to achieve the function of flexibly adjusting resistance during kayaking, providing athletes with diverse training resistance conditions, and helping athletes to train more scientifically and efficiently. Summary of the invention

[0005] The purpose of the present invention is to solve the defects in the prior art and to propose a kayak resistance device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A kayak resistance device comprises a connecting frame, on which a connecting frame and a fixing rod are arranged; the connecting frame is used to be connected to a kayak, a sliding sleeve is slidably connected to the fixing rod, and the position of the sliding sleeve is controlled by a control component; an articulated disk is fixedly connected to the end of the fixing rod, the sliding sleeve and the articulated disk are connected via a plurality of articulated frames, flexible water-blocking plates are fixedly connected between adjacent articulated frames, and a plurality of the flexible water-blocking plates enclose a resistance cover.

[0008] Furthermore, the connecting frame includes a transverse plate and a longitudinal frame, the transverse plate is fixedly connected to the longitudinal frame and is vertically arranged, the fixing rod is arranged on the transverse plate, and the connecting frame is arranged on the longitudinal frame.

[0009] Furthermore, the fixed rod is a two-section structure, including a first fixed rod and a second fixed rod, the diameter of the first fixed rod is larger than the diameter of the second fixed rod; the control component includes a threaded sleeve and a drive motor, the drive motor is arranged in a connecting frame, the drive motor is used to drive the threaded sleeve to rotate, the threaded sleeve is rotatably connected to the second fixed rod, and the sliding sleeve is threadedly connected to the threaded sleeve; a limit strip is fixedly connected to the surface of the first fixed rod, the length direction of the limit strip is parallel to the axis of the first fixed rod, and a limit ring is sleeved on the first fixed plate, and the limit ring is fixedly connected to the sliding sleeve through a connecting rod.

[0010] Furthermore, a driving compartment is provided on the connecting frame, the driving motor is a waterproof motor and is arranged in the driving compartment, the end of the threaded sleeve is provided with a driving part, and the driving motor is transmission-connected to the driving part.

[0011] Furthermore, the articulated frame includes a first articulated rod and a second articulated rod, the first end of the first articulated rod is articulated to the articulated plate, the second end of the first articulated rod is fixedly connected to the first end of the second articulated rod, and the second end of the second articulated rod is articulated to the articulated seat on the sliding sleeve.

[0012] Furthermore, reinforcement strips are provided at the edges of the flexible water blocking plate.

[0013] Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Through the setting of the present invention, a kayak resistance device is proposed, which utilizes the interaction between water flow and resistance cover to achieve the function of flexibly adjusting resistance during kayaking, provides athletes with diverse training resistance conditions, and helps athletes to train more scientifically and efficiently.

[0016] When the kayak paddles forward, the water flow impacts the resistance cover. At this time, the resistance cover formed by multiple flexible water-blocking plates interacts with the water flow. Because the flexible water-blocking plate has a certain degree of flexibility, it will deform under the impact of the water flow. This deformation can better fit the water flow shape, increase the contact area with the water flow, and thus generate greater resistance. Moreover, by adjusting the position of the sliding sleeve through the control component, changing the angle of the articulated frame, and then changing the shape and opening degree of the resistance cover, the size of the resistance can be flexibly adjusted. For example, when the sliding sleeve slides toward the hinged disk, the angle of the articulated frame becomes smaller, the opening degree of the resistance cover decreases, the obstruction encountered by the water flow when passing through is relatively reduced, and the resistance becomes smaller; conversely, when the sliding sleeve slides away from the articulated disk, the angle of the articulated frame becomes larger, the opening degree of the resistance cover increases, the obstruction encountered by the water flow when passing through increases, and the resistance becomes larger.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Reference Figure 1-Figure 2A kayak resistance device includes a connecting frame 11, on which a connecting frame 12 and a fixing rod are arranged; the connecting frame 12 is used to connect with the kayak, and a sliding sleeve 8 is slidably connected to the fixing rod, and the position of the sliding sleeve 8 is controlled by a control component; an articulated disk is fixedly connected to the end of the fixing rod, and the sliding sleeve 8 and the articulated disk are connected through multiple groups of articulated frames 3, and flexible water-blocking plates 1 are fixedly connected between adjacent articulated frames 3, and multiple flexible water-blocking plates 1 form a resistance cover.

[0024] When in use, the resistor is first firmly connected to the kayak through the connecting frame 12 on the connecting frame 11 to ensure that it will not be detached during the rowing process, thereby providing basic support for the realization of subsequent functions.

[0025] During the kayaking process, the control component starts to work. It accurately controls the sliding position of the sliding sleeve 8 on the fixed rod according to actual needs. When the position of the sliding sleeve 8 changes, since the sliding sleeve 8 and the hinge plate are connected through multiple sets of hinge frames 3, and the flexible water blocking plate 1 is fixedly connected between adjacent hinge frames 3, the hinge frames 3 will change their angles as the sliding sleeve 8 moves.

[0026] When the kayak paddles forward, the water flow impacts the resistance cover. At this time, the resistance cover formed by multiple flexible water-blocking plates 1 interacts with the water flow. Because the flexible water-blocking plate 1 has a certain flexibility, it will deform under the impact of the water flow. This deformation can better fit the water flow shape, increase the contact area with the water flow, and thus generate greater resistance. Moreover, by adjusting the position of the sliding sleeve 8 through the control component, changing the angle of the articulated frame 3, and then changing the shape and opening degree of the resistance cover, the size of the resistance can be flexibly adjusted. For example, when the sliding sleeve 8 slides toward the hinged disk, the angle of the articulated frame 3 becomes smaller, the opening degree of the resistance cover decreases, the obstruction encountered by the water flow when passing through is relatively reduced, and the resistance becomes smaller; conversely, when the sliding sleeve 8 slides away from the articulated disk, the angle of the articulated frame 3 becomes larger, the opening degree of the resistance cover increases, the obstruction encountered by the water flow when passing through increases, and the resistance becomes larger.

[0027] This canoe resistance device uses clever structural design and the interaction between water flow and resistance cover to achieve the function of flexibly adjusting resistance during canoeing, providing athletes with diverse training resistance conditions, and helping athletes to train more scientifically and efficiently.

[0028] In other preferred embodiments, the connecting frame 11 includes a transverse plate and a longitudinal frame, the transverse plate is fixedly connected to the longitudinal frame and is vertically arranged, the fixing rod is arranged on the transverse plate, and the connecting frame 12 is arranged on the longitudinal frame.

[0029] In other preferred embodiments, the fixed rod is a two-section structure, including a first fixed rod 4 and a second fixed rod 13, and the diameter of the first fixed rod 4 is larger than the diameter of the second fixed rod 13; the control component includes a threaded sleeve 9 and a drive motor, and the drive motor is arranged in the connecting frame 11, and the drive motor is used to drive the threaded sleeve 9 to rotate, and the threaded sleeve 9 is rotatably connected to the second fixed rod 13, and the sliding sleeve 8 is threadedly connected to the threaded sleeve 9; a limit strip 5 is fixedly connected to the surface of the first fixed rod 4, and the length direction of the limit strip 5 is parallel to the axis of the first fixed rod 4, and a limit ring 6 is sleeved on the first fixed plate, and the limit ring 6 is fixedly connected to the sliding sleeve 8 through a connecting rod 7.

[0030] After the driving motor is started, it drives the threaded sleeve 9 to rotate. Since the sliding sleeve 8 is threadedly connected to the threaded sleeve 9, under the transmission effect of the thread, the sliding sleeve 8 can accurately move along the axis direction of the second fixed rod 13. This method of driving the thread by the motor not only saves more effort, but also can achieve more accurate displacement control, so that athletes can quickly and accurately adjust the position of the sliding sleeve 8 according to real-time training needs during kayaking, thereby changing the resistance of the resistance cover, greatly improving the flexibility and scientificity of training.

[0031] The cooperation of the limit strip 5 and the limit ring 6 effectively limits the movement trajectory of the sliding sleeve 8, ensuring that it can only move linearly along the direction of the limit strip 5, avoiding the sliding sleeve 8 from shaking or deflecting during the movement, and ensuring the stability and reliability of the resistance adjustment. At the same time, this limit structure also further enhances the stability of the entire resistor structure, making the performance of the resistor more reliable during long-term use, and reducing the probability of failure caused by component displacement deviation.

[0032] Specifically, a driving compartment 10 is provided on the connecting frame 11 . The driving motor is a waterproof motor and is arranged in the driving compartment 10 . A driving part 14 is provided at the end of the threaded sleeve. The driving motor is transmission-connected to the driving part 14 .

[0033] In other preferred embodiments, the articulated frame 3 includes a first articulated rod and a second articulated rod, the first end of the first articulated rod is articulated to the articulated plate, the second end of the first articulated rod is fixedly connected to the first end of the second articulated rod, and the second end of the second articulated rod is articulated to the articulated seat on the sliding sleeve 8.

[0034] In other preferred embodiments, a reinforcement strip 2 is provided at the edge of the flexible water blocking plate 1. The reinforcement strip 2 is made of high-strength fiber material, such as carbon fiber or high-strength nylon fiber. The presence of the reinforcement strip 2 significantly enhances the tear resistance of the edge of the flexible water blocking plate 1. Since the impact force of the water flow on the edge of the water blocking plate is relatively concentrated during canoeing, it is easy to cause edge wear and tear. The reinforcement strip 2 can effectively disperse these concentrated stresses, greatly extend the service life of the flexible water blocking plate 1, reduce the frequency of replacing the water blocking plate due to edge damage, and reduce maintenance costs. At the same time, the reinforced edge is smoother and more stable, and can better maintain the shape of the water blocking plate under the impact of water flow, ensuring that the resistance characteristics of the entire resistance cover are stable.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
