Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic control wheels, in particular to a magnetic control wheel for a fitness bike. Background Art

[0002] Magnetic wheels are a cutting-edge technology widely used in exercise bikes. They utilize the magnetic force between magnets and metal to generate resistance. By adjusting the distance between the magnets and the metal wheel, or the strength of the magnetic field, the resistance can be varied. This method is smoother, quieter, and offers more precise resistance adjustment than traditional friction-based resistance systems.

[0003] The magnetic control wheels of exercise bikes are mostly installed inside the outer shell of the exercise bike. After long-term use, the rotating shaft of the magnetic control wheel and the parts where other components are installed need to be lubricated to reduce wear. However, the current lubrication method is mostly to pour lubricating oil on the rotating shaft from the outside, and the lubricating oil slowly penetrates into the shaft, which is slow and easy to cause the lubricating oil to flow everywhere, resulting in waste. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a magnetically controlled wheel for an exercise bike.

[0005] To achieve the above-mentioned objectives, the present invention proposes a magnetic control wheel for an exercise bike, comprising a magnetic control wheel body, a main shaft mounted on the magnetic control wheel body, mounting plates provided on both sides of the magnetic control wheel body, the mounting plates being rotatably connected to the main shaft, the lower surfaces of the two mounting plates being fixedly connected to a base plate, the upper surface of the base plate being provided with a box body, the main shaft passing through the box body and being rotatably connected to the box body, a lubrication assembly provided in the box body, and a magnetic device installed between the two mounting plates.

[0006] In one example, both ends of the main shaft are provided with oil filling holes, a delivery pipe is provided inside the main shaft, an oil outlet hole is provided outside the main shaft, and the oil filling holes are located in the box.

[0007] In one example, the lubrication assembly includes a horizontal plate, which is fixedly connected to the box body, a vertical pipe fixedly connected to the horizontal plate, the vertical pipe passes through the horizontal plate, the lower end of the vertical pipe is located at the bottom of the box body, a piston is slidably connected to the box body, and the vertical pipe passes through the piston.

[0008] In one example, the inner wall of the box is fixedly connected to a support plate, the support plate is fixedly connected to a servo motor, the main shaft of the servo motor is fixedly connected to a threaded rod, the threaded rod passes through the piston and is threadedly connected to the piston, and the vertical pipe passes through the support plate.

[0009] In one example, one side of the box body is fixedly connected to a storage box, and opposite square through slots are provided on the storage box and the box body. A one-way rotating plate is installed in the square through slot, and a torsion spring is provided on the one-way rotating plate. Spare lubricating oil is stored in the storage box.

[0010] In one example, one side of the box body is fixedly connected to a return pipe, the connection between the return pipe and the box body is located on the upper side of the horizontal plate, an electric valve is installed on one side of the return pipe, and the other end of the return pipe is fixed to the upper surface of the storage box, and the return pipe is connected to the storage box.

[0011] In one example, a liquid level sensor is installed on the upper surface of the transverse plate, and the liquid level sensor is used in conjunction with the electric valve.

[0012] The magnetically controlled wheel for a fitness bike proposed by the present invention can bring the following beneficial effects:

[0013] First, by setting up an oil filling hole and a delivery pipe, lubricating oil is injected into the delivery pipe through the oil filling hole, and the oil outlet hole is located at the connection between the main shaft and other components. After the lubricating oil flows out of the oil outlet hole, it lubricates the main shaft and other components. This method can prevent the lubricating oil from flowing around and falling on other components, causing pollution, and achieve the effect of precise lubrication;

[0014] Secondly, by setting up a return pipe, after the lubricating oil enters the oil filling hole for lubrication, when the liquid level sensor senses that the liquid level is higher than the oil filling hole, the electric valve opens and the lubricating oil above the cross plate enters the storage tank through the return pipe, avoiding the liquid level above the cross plate always being higher than the oil filling hole, causing the lubricating oil to continuously enter the delivery pipeline, resulting in excessive lubrication of the main shaft and causing waste, and at the same time avoiding the lubricating oil above the cross plate from settling above the cross plate, which easily blocks the oil filling hole.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0023] like Figures 1 to 4 As shown, the embodiment of the present utility model proposes a magnetic control wheel for an exercise bike, which is characterized in that it includes a magnetic control wheel body 1, a main shaft 2 is installed on the magnetic control wheel body 1, mounting plates 3 are provided on both sides of the magnetic control wheel body 1, the mounting plates 3 are rotatably connected to the main shaft 2, the lower surfaces of the two mounting plates 3 are fixedly connected to the bottom plate 4, the upper surface of the bottom plate 4 is provided with a box body 5, the main shaft 2 passes through the box body 5 and is rotatably connected to the box body 5, a lubrication component 6 is provided in the box body 5, a magnetic device 7 is installed between the two mounting plates 3, oil filling holes 8 are provided at both ends of the main shaft 2, a delivery pipe 9 is provided inside the main shaft 2, an oil outlet hole 10 is provided on the outside of the main shaft 2, the oil filling hole 8 is located in the box body 5, and the bottom plate 4 is installed on the exercise bike. Inside the vehicle shell, the main shaft 2 on the magnetic control wheel body 1 passes through the box 5 on both sides. At this time, the oil filling hole 8 is located in the box 5. After a period of time, the lubricating component 6 injects lubricating oil into the delivery pipe 9 through the oil filling hole 8, and the oil outlet hole 10 is located at the connection between the main shaft 2 and other components. After the lubricating oil flows out of the oil outlet hole 10, it lubricates the main shaft 2 and other components and is transported from the inside of the main shaft 2. Compared with pouring the lubricating oil on the main shaft 2 from the outside, this method can prevent the lubricating oil from flowing around and falling on other components to cause pollution, thereby achieving the effect of precise lubrication. At the same time, through the built-in box 5, the lubricating oil is placed inside the box 5, which does not need to be disassembled and is easy to use.

[0024] like Figure 4As shown, the lubricating assembly 6 includes a transverse plate 61, which is fixedly connected to the box body 5, and a vertical pipe 62 is fixedly connected to the transverse plate 61. The vertical pipe 62 passes through the transverse plate 61, and the lower end of the vertical pipe 62 is located at the bottom of the box body 5. The piston 63 is slidably connected in the box body 5, and the vertical pipe 62 passes through the piston 63. The inner wall of the box body 5 is fixedly connected to the support plate 11, and the servo motor 12 is fixedly connected to the support plate 11. The main shaft 2 of the servo motor 12 is fixedly connected to the threaded rod 13, and the threaded rod 13 passes through the piston 63 and is threadedly connected to the piston 63. The vertical pipe 62 passes through the support plate 11, and the lubricating oil is located on the lower surface of the piston 63. When the main shaft 2 on the magnetic control wheel body 1 is rotated, the servo motor 12 drives the threaded rod 13 to rotate, and the threaded rod 13 controls the piston 63 to descend. The piston 63 squeezes the lubricating oil, forcing the lubricating oil to enter the delivery pipe 9 through the oil filling hole 8 and lubricate the main shaft 2 through the oil outlet hole 10. There is no need for staff to disassemble the outer shell of the fitness bike, which is more convenient to use and conducive to improving efficiency.

[0025] like Figure 2 and Figure 4 As shown, one side of the box body 5 is fixedly connected to the storage box 14, and the storage box 14 and the box body 5 are provided with opposite square through grooves, and a one-way rotating plate 15 is installed in the square through groove. The one-way rotating plate 15 is provided with a torsion spring. Spare lubricating oil is stored in the storage box 14, and an air hole is provided on the storage box 14. When it is needed, the servo motor 12 drives the threaded rod 13 to rotate in the opposite direction, and the control piston 63 rises. Under the action of the external atmospheric pressure, the lubricating oil in the storage box 14 is squeezed, and the one-way rotating plate 15 is pushed open to enter the box body 5 for use, automatically replenishing the internal lubricating oil, greatly extending the use time.

[0026] like Figure 4 As shown, one side of the box body 5 is fixedly connected to the return pipe 16, and the connection between the return pipe 16 and the box body 5 is located on the upper side of the transverse plate 61. An electric valve is installed on one side of the return pipe 16, and the other end of the return pipe 16 is fixed to the upper surface of the storage box 14. The return pipe 16 is connected to the storage box 14. A liquid level sensor is installed on the upper surface of the transverse plate 61. The liquid level sensor is used in conjunction with the electric valve. When the lubricating oil enters the upper part of the transverse plate 61, it gathers above the transverse plate 61. Only when the lubricating oil level above the transverse plate 61 reaches the oil filling hole 8, Only then can it enter the delivery pipe 9 for lubrication. After the lubricating oil enters the oil filling hole 8 for lubrication, when the liquid level sensor senses that the liquid level is higher than the oil filling hole 8, the electric valve opens at this time, and the lubricating oil above the cross plate 61 enters the storage tank 14 through the return pipe 16, so as to prevent the liquid level above the cross plate 61 from always being higher than the oil filling hole 8, causing the lubricating oil to continuously enter the delivery pipe 9, resulting in excessive lubrication of the main shaft 2 and waste. At the same time, it prevents the lubricating oil above the cross plate 61 from settling above the cross plate 61 and easily blocking the oil filling hole 8.

[0027] Working principle: The servo motor 12 drives the threaded rod 13 to rotate, and the threaded rod 13 controls the piston 63 to descend. The piston 63 squeezes the lubricating oil, forcing the lubricating oil to enter the delivery pipe 9 through the oil filling hole 8, and lubricates the main shaft 2 through the oil outlet hole 10. After the lubricating oil enters the oil filling hole 8 for lubrication once, when the liquid level sensor senses that the liquid level is higher than the oil filling hole 8, the electric valve opens, and the lubricating oil above the horizontal plate 61 enters the storage tank 14 through the return pipe 16.

Each embodiment focuses on the differences between the other embodiments.
