Technical Field

[0001] The invention relates to the field of machinery, and in particular to a liquid damping device with adjustable resistance and a riding platform. Background Art

[0002] The damping device is a device that absorbs motion energy or provides motion resistance. Its excellent energy absorption characteristics make it widely used in scientific research and application fields, especially in aerospace, aviation, military, guns, automobiles and other industries. With the improvement of people's living standards and the rise of the fitness industry, it has also been rapidly popularized in the fitness equipment industry. For example, cycling platforms for simulated cycling training and rowing machines for simulated rowing training are equipped with damping devices.

[0003] Common damping devices can be roughly divided into three types according to the principle of generating resistance, namely electromagnetic damping devices, gas damping devices and liquid damping devices. Liquid damping devices use damping fluid to provide resistance. Since the damping fluid itself is smooth and soft, the resistance it provides is often smooth. In addition, liquid damping devices are noiseless during operation, so they have been used in many fields.

[0004] However, the liquid damping devices in the prior art are often unable to adjust the resistance, or can only adjust the resistance by replacing damping fluids of different viscosities, which not only consumes the user's labor, but also has little effect in changing the resistance, thereby limiting the application of the liquid damping device and weakening the user's satisfaction with the equipment related to the liquid damping device.

[0005] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0036] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The present invention discloses a liquid damping device with adjustable resistance, such as Figure 1 and Figure 2As shown, the resistance-adjustable liquid damping device includes a frame 300, an axis mechanism 200, a flywheel 400 and a liquid damping mechanism 100. One end of the frame 300 is connected to the liquid damping mechanism 100, and the axis mechanism 200 extending from the other end of the frame 300 is connected to the flywheel 400, thereby providing smooth and continuous resistance for the resistance-adjustable liquid damping device through the operation of the liquid damping mechanism 100 and the rotation of the flywheel 400. The axis mechanism 200 is arranged on the frame 300, and the frame 300 can be flexibly arranged in different places or assembled with different external devices, thereby expanding the application location and application range of the resistance-adjustable liquid damping device. For example, the resistance-adjustable liquid damping device can be fixed to a wall, the ground and other places through the frame 300, so that users can apply the resistance-adjustable liquid damping device according to different terrain structures.

[0038] like Figure 2 and Figure 3 As shown, the frame 300 is provided with an interface 311 at a position corresponding to the shaft mechanism 200, so that the heat generated by the shaft mechanism 200 during rotation can be released outward through the interface 311 to reduce the temperature of the shaft mechanism 200. The resistance-adjustable liquid damping device can also be connected to different external devices through the interface 311, so that the external device obtains resistance, or offsets the energy generated by the external device.

[0039] like Figure 3 As shown, the shaft mechanism 200 may include a shaft rod 210, a first rolling bearing 231 and a second rolling bearing 232. For example, the first rolling bearing 231 is arranged at one end of the frame body 300, and the second rolling bearing 232 is arranged at the other end of the frame body 300. The shaft rod 210 is movably connected to the frame body 300 through the first rolling bearing 231 and the second rolling bearing 232, thereby allowing the shaft rod 210 to rotate smoothly and with low wear. At least one sleeve 220 may be sleeved on the outer side of the shaft 210, and different connecting components may be provided on the outer side of the sleeve 220 to achieve connection with external equipment through various connection methods. For example, a first sleeve and a second sleeve are sleeved on the shaft 210, and a strip anti-slip pattern is provided on the outer side of the first sleeve. The first sleeve can be used for an external device to contact the first sleeve and drive the shaft 210 to rotate to obtain resistance. A gear is provided on the outer side of the second sleeve, and the second sleeve can be used for an external device to connect to the gear through a chain to obtain resistance through the chain. Thus, a liquid damping device with adjustable resistance can be flexibly connected to external equipment in various connection forms.

[0040] Fan blades may also be provided at both ends of the sleeve 220, so that when the shaft 210 drives the sleeve 220 to rotate, the fan blades and the air friction generate resistance, thereby increasing the resistance of the adjustable resistance liquid damping device. When the blades rotate, wind may also be generated to accelerate the heat dissipation speed of the shaft mechanism 200. For example, the wind generated by the fan blades driven by the sleeve 220 may accelerate the release of heat generated by the rotational friction of the shaft 210, the first rolling bearing 231 and the second rolling bearing 232, and also cool down the external device connected to the shaft mechanism 200 to prevent the external device from overheating and aging.

[0041] like Figure 2 and Figure 4 As shown, the liquid damping mechanism includes a cavity 140, a rotating disk 110 and a liquid level height adjustment mechanism 120. The cavity 140 is connected to the frame 300. A damping liquid is arranged in the cavity 140, so that the rotating disk 110 rotates in the damping liquid to provide resistance for the liquid damping mechanism 100. It should be noted that the damping liquid in the cavity 140 in the present invention generally refers to a substance with a liquid-like flow property, which can be any liquid substance, a solid-liquid mixture, a granular substance, etc. The damping liquid in the cavity 140 does not completely fill the space in the cavity 140. For example, the cavity 140 is injected with lubricating oil that accounts for 50% of the volume of the cavity 140 space, so that a part of the rotating disk 110 is in contact with the lubricating oil, thereby adjusting the height of the rotating disk 110 contacting the damping liquid level to adjust the size of the resistance of the rotating disk 110, so as to control the size of the output resistance of the liquid damping device with adjustable resistance.

[0042] like Fig.13 and Fig.14As shown, the cavity 140 may include a first shell 141 and a second shell 142, the second shell 142 is connected to the frame 300, the second shell 142 is detachably connected to the first shell 141, and the first shell 141 can be rotatably connected to the second shell 142. A first adjustment groove 128 may also be provided on the side of the first shell 141 facing the second shell 142, and the user may rotate the first shell 141 to adjust the position of the first adjustment groove 128 in the cavity 140 according to the required resistance demand, thereby adjusting the resistance by adjusting the height of the liquid level of the damping fluid in the cavity 140, for example, the first adjustment groove 128 is located at the top of the cavity 140, and the user rotates the first shell 141 180 degrees clockwise so that the first adjustment groove 128 is located at the bottom of the cavity 140, the damping fluid flows into the first adjustment groove 128, and the liquid level of the damping fluid in the cavity 140 is reduced, thereby the resistance encountered by the rotating disk 110 when rotating in the damping fluid becomes relatively small. The first adjusting groove 128 is provided on the first housing 141, and the processing technology is simple and the cost is low. For example, the first adjusting groove 128 can be quickly manufactured by stamping. The first adjusting groove 128 can be driven to rotate by rotating the first housing 141. The operation is simple and convenient, and the user can operate it without special training.

[0043] like Figure 4 As shown, the cavity 140 can also be composed of a third shell 143 and a fourth shell 144. The third shell 143 is connected to the frame 300, and the third shell 143 and the fourth shell 144 are detachably connected, thereby making it convenient for the user to replace the damping fluid in the cavity 140 or repair or maintain the rotating disk 110, the adjusting disk 121 and other components in the cavity 140.

[0044] like Figure 2 As shown, the rotating disk 110 is connected to the shaft 210, for example, the shaft 210 is connected to the center of the rotating disk 110, so that the rotating disk 110 can rotate synchronously with the shaft 210, so that the resistance of the damping fluid on the rotating disk 110 is transmitted to the external device through the shaft mechanism 200. It should be noted that the shaft 210 can also indirectly drive the rotating disk 110 to rotate synchronously through magnetic force. For example, the shaft 210 is connected to a magnet, and another magnet magnet is provided on the rotating disk 110. When the shaft 210 rotates, the rotating disk 110 rotates under the action of the magnetic force.

[0045] like Figure 2As shown, the rotating disk 110 is provided with blades 111, so that when the rotating disk 110 is driven by an external device to rotate, the blades 111 rotate synchronously with the rotating disk 110, thereby generating resistance through the interaction between the blades 111 and the damping fluid in the cavity 140. The blades 111 can also be connected to the rotating disk 110 at an adjustable angle, so that the resistance of the damping fluid to the rotating disk 110 can be adjusted. For example, the blades 111 arranged at an angle relative to the rotating disk 110 are detachably connected to the rotating disk 110 by screws, and the user can also connect the blades 111 relative to the rotating disk 110 at another angle, so that the resistance of the damping fluid to the blades 111 at different angles is different, so as to output resistances of different sizes. When the blades 111 rotate with the rotating disk 110, the blades 111 located above the liquid level can also disturb the air to generate wind, thereby cooling the cavity 140.

[0046] like Figure 4 As shown, the liquid level height adjusting mechanism 120 is arranged in the cavity 140 to control the liquid level height of the damping fluid in the cavity 140. Therefore, when the rotating disk 110 rotates in the damping fluid at a fixed speed, the higher the liquid level height of the rotating disk 110 immersed in the damping fluid, the greater the resistance of the damping fluid to the rotating disk 110, and the lower the liquid level height of the rotating disk 110 immersed in the damping fluid, the smaller the resistance to the rotating disk 110. Therefore, the size of the resistance can be controlled by adjusting the height of the damping fluid by the liquid level adjusting mechanism 120.

[0047] like Figure 5 As shown, the liquid level height adjustment mechanism 120 can be an adjustment disk 121, and at least one recess 122 is provided on the adjustment disk 121. The recess 122 can be a groove with a volume gradually deepening in the adjustment disk 121, thereby controlling the volume of the damping liquid immersed in the recess 122 to control the height of the damping liquid in the cavity 140, thereby controlling the size of the resistance of the damping liquid when the rotating disk 110 rotates. Taking a liquid damping device of a fitness equipment cycling platform as an example, the recess 122 is provided on the adjustment disk of the liquid damping device of the cycling platform, as shown in FIG. Figure 6 As shown, the adjusting plate 121 is rotated so that the recess 122 is located at the lower end of the cavity 140, that is, the recess 122 is immersed in the damping fluid, and the damping fluid flows into the space in the recess 122. The liquid level of the damping fluid in the cavity 140 is low, and the resistance of the damping fluid to the rotating plate 110 during rotation is small, thereby satisfying the entertainment experience of users such as children who can ride quickly with less force. Figure 7 As shown, the adjusting disk 121 is rotated so that the concave portion 122 is located at the upper end of the liquid surface of the damping liquid, that is, when the plane portion of the adjusting disk 121 is immersed in the damping liquid, the liquid level of the damping liquid in the cavity 140 rises, and the rotating disk 110 is subjected to a large resistance from the damping liquid when rotating, thereby satisfying the need for adult users to overcome resistance with great effort to enhance the intensity of physical training. Thus, by controlling the volume of the concave portion 122 of the rotating disk 110 immersed in the damping liquid to control the size of the resistance of the liquid damping mechanism, the personalized needs of different user groups can be met.

[0048] like Figure 8 As shown, the recess 122 can be a through hole, whereby, when the adjusting disk 121 is rotated to adjust the liquid level height of the damping fluid, the damping fluid flowing into the through hole can quickly flow out of the through hole, so that the liquid level height of the damping fluid quickly reaches a corresponding height, thereby causing the rotating disk 110 to quickly receive a resistance corresponding to the liquid level height.

[0049] like Figure 5 As shown, an adjusting rod 123 is provided on the adjusting disk 121, and the adjusting rod 123 extends to the outside of the cavity 140, so that the user can adjust the resistance in real time by rotating the adjusting rod 123 from the outside to drive the adjusting disk 121 to rotate. For example, an adjusting rod 123 is provided at the center of the adjusting disk 121, and the adjusting rod 123 extends out of the resistance adjustable liquid damping device through the cavity formed by the shaft mechanism 200 and the flywheel 400, so that the user can rotate the adjusting rod 123 on one side of the flywheel 400 to control the resistance. The adjusting rod 123 can also extend to the outside of the resistance adjustable liquid damping device through the fourth housing 144, so that the user can rotate the adjusting rod 123 to adjust the resistance. The user can connect the adjusting rod 123 through the intelligent motor, and control the rotation degree of the motor to control the corresponding degree of rotation of the adjusting disk 121 through the adjusting rod 123, thereby controlling the liquid level of the damping liquid in the cavity 140. The intelligent motor to control the speed or rotation angle is a mature prior art and does not belong to the protection invention of the present invention, so it will not be repeated here. Figure 4 As shown, the user can also provide a handle 124 at one end of the adjusting rod 123 extending from the resistance-adjustable liquid damping device, and the end of the handle 124 can be locked with the cavity 140, so that the user can manually adjust the adjusting rod 123, and fix the handle 124 after achieving a satisfactory effect to ensure that the resistance effect remains unchanged, thereby realizing manual and quick adjustment of the resistance size under no-electricity conditions, which is convenient for users to use.

[0050] like Fig. 9 and Fig.10 As shown, the liquid level height adjustment mechanism 120 can also be a slider 125 disposed in the cavity 140, so as to control the liquid level of the damping liquid in the cavity 140 by the volume of the slider 125 immersed in the damping liquid, thereby controlling the magnitude of the resistance of the damping liquid to the rotating disk 110. For example, a slideway 126 is disposed inside the fourth shell 144 of the cavity 140, and the slider 125 can slide up and down in the slideway 126. A magnet 127 is disposed on the slider 125, so that the user can control the slider 125 to move along the slideway 126 through another magnet outside the liquid damping device with adjustable resistance, so as to change the liquid level of the damping liquid in the cavity 140, that is, the larger the volume of the slider 125 immersed in the damping liquid, the higher the liquid level of the damping liquid, and the greater the resistance to the rotating disk 110. It should be noted that the sliding direction of the slider 125 in the cavity 140 is not limited. For example, the slider 125 can also slide in the direction close to the rotating disk 110 and in the direction away from the rotating disk 110. The height of the slider 125 is higher than the liquid level of the damping fluid in the cavity 140 when the slider 125 is closest to the rotating disk 110. Therefore, when the slider 125 slides in the direction of the rotating disk 110, the liquid level of the damping fluid gradually increases. As the height of the volume of the rotating disk 110 immersed in the damping fluid increases, the resistance of the damping fluid to the rotating disk 110 when it rotates is greater. On the contrary, when the slider 125 slides in the direction away from the rotating disk 110, the liquid level of the damping fluid decreases, and the resistance to the rotating disk 110 when it rotates becomes smaller accordingly. Through the simple operation of the slider 125 sliding in the cavity 140, the size of the resistance of the damping fluid to the rotating disk 110 can be changed.

[0051] like Figure 2 and Fig.11 As shown, the cavity 140 is further provided with an inner sleeve 130, which is detachably provided inside the cavity 140, and can be of any structure, such as conical or cylindrical, so as to adjust the resistance of the damping fluid to the rotating disk 110 by cooperating with the liquid level height adjustment mechanism 120 through different structural features. The inner side of the inner sleeve 130 is further provided with resistance ribs 131, which can be of various structures, such as spiral stripes, concave-convex structures, etc., so as to cooperate with the liquid level height adjustment mechanism 120 to increase the resistance effect.

[0052] The inner sleeve 130 may also be provided with a second adjustment groove, and the user may adjust the position of the second adjustment groove in the cavity 140 by rotating the inner sleeve 130, thereby controlling the height of the damping liquid level in the cavity 140 to conveniently adjust the resistance. For example, the second adjustment groove is located at the bottom of the cavity 140, and the user may rotate the inner sleeve 130 to rotate the second adjustment groove 140 to the top of the cavity 140, and then clamp the inner sleeve 130 in the cavity 140, thereby increasing the level of the damping liquid and correspondingly increasing the resistance of the damping liquid to the rotating disk 110.

[0053] like Fig.12 As shown, the present invention further discloses a cycling platform 500, which includes a support frame 510 and the liquid damping device with adjustable resistance. The structural features and corresponding technical effects of the liquid damping device with adjustable resistance are the same as those described above and will not be described in detail here. When a user trains with the cycling platform 500, the user can adjust the size of the resistance according to his or her own training requirements or training plan throughout the training process, and conduct targeted personalized training.

[0054] In order to illustrate the hydraulic damping device with adjustable resistance and the riding platform of the present invention, an embodiment is taken as an example below.

[0055] like Fig.12 As shown, a cycling platform 500 includes a support frame 510 and a liquid damping device with adjustable resistance, wherein the liquid damping device with adjustable resistance is arranged at the bottom end of the support frame 510, and the support frame 510 is used to fix the bicycle so that the rear wheel of the bicycle contacts the liquid damping device with adjustable resistance, so that the user can ride the bicycle in place, so that the rear wheel of the bicycle obtains a smooth resistance from the liquid damping device with adjustable resistance, which is similar to riding a bicycle, and the user obtains a similar riding feeling indoors.

[0056] like Figure 1 and Figure 3As shown, the adjustable resistance liquid damping mechanism includes a frame 300, the frame 300 includes a fixed frame 320 and a connecting frame 310, the fixed frame 320 is used to connect with the support frame 510, the fixed frame 320 can be connected with the support frame 510 at an adjustable angle and position on the support frame 510, so that the rear tire of the bicycle can accurately contact the adjustable resistance liquid damping device. The connecting frame 310 is arranged at the upper end of the fixed frame 320, the connecting frame 310 is a cylindrical structure, one end of the connecting frame 310 is provided with a first rolling bearing 231, and the other end of the connecting frame 310 is provided with a second rolling bearing 232, a shaft 210 is movably connected to the connecting frame 310 through the first rolling bearing 231 and the second rolling bearing 232, so that the shaft 210 can rotate smoothly and with low wear.

[0057] like Figure 2 and Figure 3 As shown, a sleeve 220 is disposed on the shaft rod 210, and the sleeve 220 is used to contact the rear tire of the bicycle, so that when the rear tire of the bicycle contacts and rotates with the sleeve 220, the sleeve 220 is driven to rotate synchronously, thereby driving the shaft rod 210 to rotate, thereby obtaining the resistance of the liquid damping device with adjustable resistance. Anti-skid stripes are arranged on the outer side of the sleeve 220, so that the rear tire of the bicycle is in stable contact with the sleeve 220, to prevent slipping and wear of the rear tire of the bicycle. The connecting frame 310 is provided with an interface 311 at a position corresponding to the sleeve 220, so that the rear tire of the bicycle is in contact with the sleeve 220.

[0058] like Figure 1 and Figure 2 As shown, one end of the connecting frame 310 facing the cavity 140 is provided with an outwardly extending edge, and the cavity 140 is provided with a protrusion adapted to the edge at a position corresponding to the edge, so that the protrusion is clamped into the edge, thereby increasing the stability of the connection between the frame 300 and the cavity 140.

[0059] like Figure 4 As shown, the cavity 140 is composed of a third shell 143 and a fourth shell 144 that are detachably connected to facilitate the user to replace the silicone oil in the cavity 140. A sealing ring is provided between the third shell 143 and the fourth shell 144 to prevent the silicone oil in the cavity 140 from leaking out. The silicone oil in the cavity 140 occupies one-half of the volume of the cavity 140, thereby providing resistance for the liquid damping mechanism through the silicone oil.

[0060] like Figure 2 and Figure 4As shown, a rotating disk 110 is connected to a shaft 210 extending into the cavity 140, and a plurality of blades 111 are radially arranged on the rotating disk 110, so that the blades 111 obtain resistance when contacting the silicone oil in the cavity 140. When the rotating disk 110 rotates, the blades 111 located on the silicone oil liquid surface can generate wind to reduce the temperature in the cavity 140 during rotation.

[0061] like Figure 4 and Figure 8 As shown, an adjusting disk 121 is further provided on one side of the fourth shell 144, and a first through hole 151, a second through hole 152, a third through hole 153 and a fourth through hole 154 are provided on the adjusting disk 121. An adjusting rod 123 is provided at the center position of the adjusting disk 121, and the adjusting rod 123 extends to the outside through the fourth shell 144 and is controlled by a handle 124. The fourth shell 144 is provided with a positioning hole corresponding to the position of the handle 124. When the user needs to use a large resistance, the user shakes the handle 124 to rotate the adjustment disk 121, so that the non-through hole part of the adjustment disk 121 is immersed in the silicone oil, so that the liquid level of the silicone oil in the cavity 140 reaches the highest height, and the handle 124 is fixed to the fourth shell 144 through the positioning hole to ensure that the adjustment disk 121 is fixed relative to the fourth shell 144, so that the silicone oil liquid level in the cavity 140 is stable. When the user is riding, the rotating disk 110 is subjected to a large resistance of the silicone oil, so that the user obtains the corresponding resistance. When the user needs to reduce the difficulty of training, the user rotates the handle 124 and adjusts the rotating disk 110, so that the first through hole 151 and the second through hole 152 are immersed in the silicone oil. The silicone oil is immersed in the first through hole 151 and the second through hole 152, and the silicone oil liquid level in the cavity 140 is reduced. When the rotating disk 110 rotates, the resistance of the silicone oil becomes smaller, and the user obtains a smaller resistance accordingly. When the user further reduces the riding resistance, the user rotates the handle 124 so that the first through hole 151, the second through hole 152 and the third through hole 153 are immersed in the silicone oil. The silicone oil quickly enters the third through hole 153, and the silicone oil level is further reduced. When the rotating disk 110 rotates, the resistance is correspondingly reduced, thereby meeting the user's low-resistance training needs.

[0062] In summary, the present invention discloses a liquid damping device with adjustable resistance, which includes a frame 300, an axis mechanism 200, a flywheel 400 and a liquid damping mechanism 100, wherein the axis mechanism 200 is arranged on the frame 300, and the flywheel 400 and the liquid damping mechanism 100 are respectively arranged at two ends of the frame 300, thereby providing smooth resistance for the liquid damping mechanism with adjustable resistance. The liquid damping mechanism includes a cavity 140, a rotating disk 110 and a liquid level height adjustment mechanism 120, wherein the cavity 140 is used to contain damping liquid, so as to provide resistance to the rotating disk 110 when the rotating disk 110 rotates in the damping liquid. The rotating disk 110 is provided with a blade 111, and the angle of the blade 111 relative to the rotating disk 110 is adjustable, so as to obtain resistance of different sizes by adjusting the angle. The liquid level height adjustment mechanism 120 can be an adjustment disk 121 provided with a recess 122. The damping liquid is immersed in the recess 122 to change the liquid level of the damping liquid in the cavity 140 to control the size of the resistance. The adjustment disk 121 is also provided with an adjustment rod 123, which extends out of the outside of the cavity 140 so that the user can control the resistance in real time outside the cavity 140 to meet the user's personalized needs. The liquid level height adjustment mechanism 120 can also be a slider 125, which can be movably connected to the cavity 140 through a slide 126 to control the height of the liquid surface by the volume of the damping liquid immersed, thereby controlling the size of the resistance. The structure is simple and the operation is convenient, and the resistance can be controlled in real time. An inner sleeve 130 is also provided in the cavity 140. The inner sleeve 130 is detachably connected to the cavity 140, so that the user can replace the inner sleeve 130 according to actual needs. Resistance ribs 131 are also provided on the inner side of the inner sleeve 130 to increase the resistance effect. A second adjustment groove can also be provided in the inner sleeve 130, so that the position of the second adjustment groove in the cavity 140 can be adjusted by rotating the inner sleeve 130, thereby adjusting the liquid level of the damping fluid in the cavity 140. The cavity can be composed of the first shell 141 and the second shell 142. The first shell 141 is provided with a first adjustment groove. The user adjusts the position of the first adjustment groove in the cavity 140 by rotating the first shell 141 to control the height of the damping liquid level and the size of the resistance. The present invention also discloses a cycling platform 500, which includes a support frame 510 and the liquid damping device with adjustable resistance. Thus, a user can connect the cycling device with the liquid damping device with adjustable resistance in a variety of ways. The resistance of the liquid damping device with adjustable resistance can also be adjusted to meet the personalized needs of the user or external equipment.
