Description

Technical Field

[0001] The present invention relates to the technical field of resistance systems for spinning bikes, in particular to a multifunctional spinning bike and a resistance control system. Background Art

[0002] A spinning bike is a piece of fitness equipment that can simulate cycling indoors. When exercising on a spinning bike, the user steps on the pedals to cause the drive wheel to rotate rapidly. The strong magnetic force applies resistance to the front wheel, allowing the user to perform aerobic exercise and enhance physical fitness. Therefore, more and more people use spinning bikes for physical exercise.

[0003] However, most spinning bikes on the market are only used for riding, and the riding state cannot be adjusted. At the same time, the riding resistance of spinning bikes is relatively small, so they are suitable for a wider group of people. If the riding resistance of spinning bikes can be adjusted, users can make reasonable adjustments according to their own usage and choose the resistance that suits them best. Some high-end spinning bikes on the market achieve adjustable riding resistance by adding resistance motors inside the wheels, but they are expensive, and if the motor is damaged, it will become unusable, causing many users not to choose to buy it. If a spinning bike with adjustable resistance can be designed, and the functions are simple and practical, and the users can replace the wearing parts by themselves, it will provide great convenience.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 , the present invention provides a technical solution:

[0032] A multifunctional spinning bicycle comprises a frame 1, a transmission housing 2, a base 3, wheels 4, a rotating shaft 5, a supporting sleeve frame 7 and a resistance member;

[0033] The frame 1 is fixedly connected to the transmission housing 2, and the bottom end of the frame 1 is fixedly connected to the base 3. The middle of the wheel 4 is fixedly connected to the shaft 5. The side end of the shaft 5 is rotatably connected to the frame 1.

[0034] The side end of the support sleeve frame 7 is fixedly connected to the auxiliary support slide rod 26, and the upper end of the support sleeve frame 7 is provided with a motor 6. The lower end surfaces of the support sleeve frame 7 and the auxiliary support slide rod 26 are fixedly connected to the upper end surface of the base 3, and the shaft end of the motor 6 is fixedly connected to the screw rod 8, which is threadedly connected to the support sleeve frame 7.

[0035] The resistance component includes a screw 8, a U-shaped frame 9, a first friction block 10, a first through hole 11, an auxiliary plug 12, a second friction block 13, an auxiliary plug 14, a second through hole 15, a threaded spike 16, a threaded cap 17, an extrusion friction block 20, an auxiliary screw hole 21, a slide 22, a threaded through hole 23, a condensing circulator 24 and a water pipe 25. The screw 8 is threadedly connected to the support sleeve frame 7, and one end of the screw is fixedly connected to the shaft end of the motor 6, and the other end passes through the threaded through hole 23 and presses into the auxiliary The screw hole 21 and the two side ends of the U-shaped frame 9 are fixedly connected to the extrusion friction block 20. The upper arc surface of the extrusion friction block 20 is provided with a condensation circulator 24, and the extrusion friction block 20 is penetrated by a water pipe 25. The slide groove 22 is opened at the lower end of the extrusion friction block 20. The side end of the first friction block 10 is provided with a first through hole 11, and the bottom surface of the side end is fixedly connected to the auxiliary plug-in block 12. The side ends of the second friction block 13 are respectively provided with an auxiliary plug hole 14 and a second through hole 15, and the threaded cap 17 is threadedly sleeved with the threaded long nail 16.

[0036] The rotating chain of the wheel 4 is located in the transmission housing 2, and a threaded through hole is opened at the side end of the plug-in circular groove 18, and the threaded through hole corresponds to the position of the threaded hole of the internal thread fixing block 19 and is the same in size. The auxiliary support slide bar 26 is adapted to the sliding connection slide groove 22, and the height of the auxiliary support slide bar 26 is lower than the bottom end cross-section of the plug-in circular groove 18; the rotating movement of the wheel 4 is driven by the transmission chain, and the movement of the transmission chain is controlled by the foot pedal, so the wheel 4 is a driven wheel. At the same time, the purpose of the low height of the auxiliary support slide bar 26 is to ensure that the extrusion friction block 20 can smoothly squeeze the two groups of friction blocks.

[0037] The auxiliary screw hole 21 and the threaded through hole 23 correspond to each other in position, and the interior of the auxiliary screw hole 21 is a smooth curved surface. The diameter of the auxiliary screw hole 21 is larger than the diameter of the threaded through hole 23, and the circular end surface of the auxiliary screw hole 21 located inside the extrusion friction block 20 is a solid surface, which is convenient for contacting the screw 8; ensuring that the screw 21 can drive the U-shaped frame 9 to move forward and backward by rotation, and its contact with the auxiliary screw hole 21 also supports the extrusion friction block 20.

[0039] There are multiple groups of water pipes 25 distributed on the extrusion friction block 20, and the water pipes 25 inside the extrusion friction block 20 form a "U"-shaped structure to achieve cooling of the extrusion friction block 20. The condensing circulator 24 runs through the connected water pipes 25 to ensure that the extrusion friction block 20 can be cooled by water, thereby reducing the temperature at the friction point and avoiding damage to components caused by high temperature generated by long-term friction.

[0040] The side end surface of the extrusion friction block 20 is provided with multiple groups of arc-shaped ridges, and the side edges of the first friction block 10 and the second friction block 13 are provided with multiple groups of annular ridges, and the positions correspond to the arc-shaped ridges, which increase the friction force and thus achieve the effect of increasing the resistance.

[0041] There are two groups of resistance components symmetrically arranged at equal distances, and the two groups of resistance components are independent of each other and can be adjusted individually to ensure that the debugging or replacement of each group will not affect each other, and the two groups are independent and can cooperate with each other to effectively control the size of the resistance.

[0042] A resistance control system includes a multifunctional spinning bicycle.

[0043] Working principle: The present invention is a multifunctional spinning bike and resistance control system. In actual use, when it is necessary to adjust the riding resistance of the spinning bike, the motor 6 is first started. When the rotating shaft of the motor 6 rotates, the screw rod 8 is driven to rotate, and then the U-shaped frame 9 is driven to move forward. When the U-shaped frame 9 moves forward, the push rods on both sides thereof drive the extrusion friction block 20 to move forward. The contact surfaces of the extrusion friction block 20 with the first friction block 10 and the second friction block 13 are provided with convex strips to increase the friction force. The extrusion force of the extrusion friction block 20 on the friction block in the plug-in circular groove 18 is adjusted to achieve resistance adjustment, that is, to adjust the rotation of the motor 6. The screw rod 8 is used to adjust the extrusion friction block 20. If the motor 6 rotates many times, it will make When the distance the friction block 20 moves forward increases, the squeezing force between the two sets of friction blocks increases, causing the resistance to increase. On the contrary, when the distance the friction block 20 moves forward decreases, the resistance decreases. When the condensing circulator 24 is started, the water flow inside the water pipe 25 can also cool the friction block 20 when it circulates. When the temperature of the friction block 20 decreases, it can indirectly cool the block when it contacts the first friction block 10 and the second friction block 13. When riding an action bike, when the pedals start to rotate, the wheel 4 is rotated by the transmission chain in the transmission housing 2. However, because the wheel 4 is limited by resistance, the rider will feel the corresponding resistance. After a long period of riding, the first friction block 10 and the second friction block 13 will be affected. To wear, at this time, it is necessary to replace the first friction block 10 and the second friction block 13, otherwise the outer edge of the plug-in circular groove 18 will be damaged by friction, adjust the motor 6 to rotate in the opposite direction, and make the U-shaped frame 9 retreat to the rear end. At this time, the width between the squeezed friction block 20 and the plug-in circular groove 18 will be greater than the width of the new friction block, so the friction block to be replaced can be smoothly taken out, and the threaded cap 17 is rotated with the help of a tool, and then the threaded nail 16 is rotated to disengage it from the first through hole 11, the second through hole 15 and the plug-in circular groove 18. If the friction block still has a part protruding from the plug-in circular groove 18, the friction block can be directly taken out manually. If it is not serious and difficult to take out, the spinning bike can be tilted, and the inertia force can be used to directly dump the two sets of friction blocks from the inside of the plug-in circular groove 18. When replacing the new first friction block 10 and second friction block 13, it is necessary to ensure that the auxiliary plug-in block 12 is smoothly inserted into the auxiliary socket 14, and fixed with the threaded nail 16 to complete the replacement operation; the overall design is relatively simple to adjust the resistance during use, and the method of replacing the friction block is also convenient. The condensation circulator 24 is used to condense the water flow inside the water pipe 25, and the friction contact point can also be cooled to reduce the loss of parts during friction. Compared with the control of the resistance motor, this design will greatly extend the service life of the spinning bike, because its resistance adjustment parts can be replaced, and it also has a cooling function, simple operation, practical functions, and can bring great convenience and experience to users.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
