A domestic intelligent treadmill

Abstract

This invention discloses a home-use smart treadmill, relating to the field of home treadmill technology. It includes an external support frame, an internal support frame slidably connected to the inner side of the external support frame, a running board fixedly connected to one side of the internal support frame, a running belt slidably connected to one side of the running board, multiple buffer grooves on one side of the running board, a drive plate and a lifting rod slidably connected inside the buffer grooves, and a spring fixedly connected to one side of the drive plate and the buffer grooves. This invention addresses the issue that when the lubricating coating wears down over time, friction causes the drive plate to slide backward when the user steps on the running belt. At this time, a ramp on one side of the drive plate presses against the lifting roller, causing the lifting rod to move downward. The downward-moving lifting rod then causes the lifting tube to move downward. The conical plug inside the lifting tube disengages from the limiting groove, and one end of the lubricating roller moves downward to contact the inner side of the running belt. This allows lubricating oil to flow through the lifting tube and the lubricating roller to lubricate the inner side of the running belt, thus resolving the dragging sensation caused by increased friction.

Description

Technical Field

[0001] This invention relates to the field of home treadmill technology, and more particularly to a home smart treadmill. Background Technology

[0002] With the development of society and economy, people are paying more and more attention to their physical health. Fitness has become a part of many people's daily life. However, due to various reasons, it is inconvenient for many people to go to the gym to exercise. Therefore, home treadmills have become a good choice. There is usually a lubricating coating between the running board and the running belt on the treadmill. However, the lubricating coating will wear down during long-term use, which will cause a dragging sensation when running, affecting the user's normal running and even causing falls.

[0003] Existing treadmill structures lack components that lubricate the running belt and running board when the lubricating coating between them wears down. As a result, the dragging sensation caused by friction cannot be automatically resolved after prolonged use. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a home-use intelligent treadmill.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A home-use smart treadmill includes an external support frame, an internal support frame slidably connected to the inner side of the external support frame, a running board fixedly connected to one side of the internal support frame, a running belt slidably connected to one side of the running board, multiple buffer grooves on one side of the running board, a drive plate and a lifting rod slidably connected inside the buffer grooves, a spring one fixedly connected to one side of the drive plate and the buffer grooves, a lifting roller rotatably connected to one end of the lifting rod, a lifting roller slidably connected to one side of the drive plate, a connecting plate fixedly connected to one side of the lifting rod, a spring two fixedly connected to one side of the connecting plate and the running board, an oil supply pipe fixedly connected to one side of the running board, an oil inlet fixedly connected to one side of the oil supply pipe, multiple fixed tubes fixedly connected to one end of the oil supply pipe, limit grooves opened inside the fixed tubes, a lifting tube fixedly connected to one end of the connecting plate, a conical plug fixedly connected inside the lifting tube, a lubrication roller slidably connected to the inside of the lifting tube, and a lubrication roller rotatably connected to one end of the lifting tube.

[0007] Preferably, one end of the internal support is fixedly connected to a magnetic levitation damping component and a damping pad, one end of the magnetic levitation damping component and the damping pad is fixedly connected to a buffer plate, and one end of the external support is fixedly connected to the buffer plate.

[0008] Furthermore: a control circuit board is fixedly connected to one side of the buffer plate, an upper bracket is fixedly connected above the external bracket, and a control screen and a handrail bracket are fixedly connected to one side of the upper bracket.

[0009] Furthermore: a drive motor is fixedly connected to one side of the internal support, and guide roller one and guide roller two are rotatably connected to one side of the internal support. A transmission belt one is connected to the power output end of the drive motor and the first end of guide roller one. The belt is connected to guide roller one and guide roller two.

[0010] As a preferred embodiment of the present invention: one end of the buffer plate is rotatably connected to a bottom support plate, and a plurality of silent rubber pads are fixedly connected below the bottom support plate.

[0011] As a further aspect of the present invention: a telescopic rod is fixedly connected to one side of the bottom support plate, a buffer is fixedly connected to the movable end of the telescopic rod, and a connecting rod is rotatably connected to one end of the buffer and the buffer plate.

[0012] As a further embodiment of the present invention: a transmission wheel and a transmission gear are rotatably connected to one side of the internal support, the transmission wheel is fixedly connected to the transmission gear on one side, a drive gear is meshed with one side of the transmission gear on one side, the drive gear is fixedly connected to the internal support on one side, and a transmission belt is drivingly connected to one side of the transmission wheel and the guide roller.

[0013] Based on the aforementioned scheme: one end of the drive gear is fixedly connected to a guide roller, one side of the guide roller is rotatably connected to an internal support, an extrusion rod is fixedly connected inside the guide roller, one side of the internal support is fixedly connected to a telescopic rod two, and the movable end of the telescopic rod two is rotatably connected to an extrusion sleeve.

[0014] Based on the aforementioned scheme: one end of the extrusion sleeve is rotatably connected to a connecting rod two, one end of the extrusion rod is rotatably connected to a connecting rod three, one end of connecting rod two and connecting rod three is rotatably connected to a sliding bracket, one end of the sliding bracket is slidably connected to a cleaning brush, and one side of the cleaning brush is slidably connected to the guide roller.

[0015] Based on the aforementioned scheme: an electric double-ended lead screw is fixedly connected to the bottom of the running board, a tensioning leaf spring is threadedly connected to the movable end of the electric double-ended lead screw, and a pressure sensor is fixedly connected to the middle of the tensioning leaf spring.

[0016] The beneficial effects of this invention are as follows:

[0017] A home-use smart treadmill, when the lubricating coating wears down after prolonged use, causes the drive plate to slide backward due to friction when the user steps on the running belt and moves backward. At this time, the inclined platform on one side of the drive plate squeezes the lifting roller, causing the lifting rod to move downward. The downward-moving lifting rod drives the lifting tube to move downward. At this time, the conical plug inside the lifting tube disengages from the limiting groove, and one end of the lubricating roller moves downward and contacts the inside of the running belt. This allows lubricating oil to lubricate the inside of the running belt through the lifting tube and the lubricating roller, thus solving the dragging sensation caused by increased friction.

[0018] A home-use smart treadmill, equipped with multiple drive plates, can apply lubricating oil only to areas with severely worn lubricating coatings, adapting to different running postures of different people and preventing excessive lubricating oil discharge from contaminating the running belt and the ground.

[0019] A home-use smart treadmill features a pressure sensor that detects a decrease in pressure value, indicating deformation in the middle of the running belt. At this point, an electric double-ended lead screw rotates, causing the two ends of the tensioning leaf spring to move inward and the middle of the tensioning leaf spring to bend outward, thus tensioning the middle of the running belt. This keeps the running belt taut and prevents deformation in the middle of the running belt after prolonged use.

[0020] A home-use smart treadmill uses guide rollers that rotate in the opposite direction to the guide rollers to tighten the running belt, allowing lubrication rollers that move downwards from above to properly contact and rotate to lubricate the inside of the running belt.

[0021] A home-use smart treadmill uses a control panel to move a telescopic rod two to one side, causing a squeezing sleeve to move outward via a connecting rod two and a connecting rod three. The outer brush portion of the squeezing cleaning brush extends outward from the guide roller, allowing the outer side of the running belt to be cleaned while the guide roller rotates.

[0035] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0036] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0037] Example 1:

[0038] A type of home smart treadmill, such as Figures 1-12As shown, the system includes an external support 1, an internal support 3 slidably connected to the inner side of the external support 1, a running plate 17 fixedly connected to one side of the internal support 3, a running belt 4 slidably connected to one side of the running plate 17, multiple buffer grooves 18 opened on one side of the running plate 17, a drive plate 19 and a lifting rod 21 slidably connected inside the buffer grooves 18, a spring 20 fixedly connected to one side of the drive plate 19 and the buffer grooves 18, a lifting roller 22 rotatably connected to one end of the lifting rod 21, one end of the lifting roller 22 slidably connected to one side of the drive plate 19, and one side of the lifting rod 21 fixedly connected to the other. A connecting plate 23 is fixedly connected to one side of the connecting plate 23 and the running plate 17. A spring 24 is fixedly connected to one side of the running plate 17. An oil supply pipe 25 is fixedly connected to one side of the oil supply pipe 25. An oil inlet 10 is fixedly connected to one side of the oil supply pipe 25. Multiple fixed pipes 26 are fixedly connected to one end of the oil supply pipe 25. A limit groove 29 is opened inside the fixed pipe 26. A lifting pipe 27 is fixedly connected to one end of the connecting plate 23. A conical plug 30 is fixedly connected inside the lifting pipe 27. The lifting pipe 27 is slidably connected to the fixed pipe 26. A lubricating roller 28 is rotatably connected to one end of the lifting pipe 27.

[0039] The running board 17 and drive plate 19 are coated with a lubricating coating. When the user runs, their feet slide against the running belt 4 and against the running board 17 and drive plate 19. The lubricating coating makes the sliding smooth and prevents dragging. After the lubricating coating wears down with prolonged use, when the user steps on the running belt 4 and moves backward, the friction will cause the drive plate 19 to slide backward. At this time, the inclined platform on one side of the drive plate 19 presses against the lifting roller 22, causing the lifting rod 21 to move downward. The downward movement of the lifting rod 21 will cause the lifting tube 27 to move downward. At this time, the conical plug 30 inside the lifting tube 27 disengages from the limiting groove 29, and the lubricating roller 28 moves downward, with one end contacting the inside of the running belt 4, allowing lubricating oil to pass through the lifting tube 27. Pipe 27 and lubrication roller 28 lubricate the inside of the running belt 4 to solve the dragging feeling caused by increased friction. At the same time, since different people have different running postures and foot step positions, multiple drive plates 19 can be installed to lubricate only the long-term friction parts, preventing a large amount of lubricating oil from being discharged and contaminating the running belt 4 and the room. Spring 1 20 and spring 2 24 can reset the drive plate 19 and the lifting rod 21. The inclined platform on one side of the drive plate 19 has a certain margin from the lifting roller 22 to prevent the lubricating oil from flowing out due to non-frictional reasons when the foot steps down when the running board 17 is tilted and the drive plate 19 moves backward due to the impact. The oil inlet 10 is located on one side of the external bracket 1, and oil can be added to the oil supply pipe 25 from the outside.

[0040] To address the issue of cushioning and shock absorption during running; such as Figures 1-12 As shown, one end of the internal support 3 is fixedly connected to a magnetic levitation damping component 47 and a damping pad 48, and one end of the magnetic levitation damping component 47 and the damping pad 48 is fixedly connected to a buffer plate 49. One end of the external support 1 is fixedly connected to the buffer plate 49.

[0041] The shock-absorbing pad 48 can work with the magnetic levitation shock-absorbing component 47 to cushion and reduce the impact on the user's knees during running, while also reducing noise transmission to prevent it from affecting other residents.

[0042] To solve the control problem of the device; such as Figures 1-12 As shown, a control circuit board 11 is fixedly connected to one side of the buffer plate 49, and an upper bracket 2 is fixedly connected above the external bracket 1. A control screen 45 and a handrail bracket 46 are fixedly connected to one side of the upper bracket 2. When running, the user can hold onto the handrail bracket 46 to stabilize their body. The control screen 45 is preferably a touch screen, which can display the device's operating data. At the same time, the buffer strength of the magnetic levitation shock absorption component 47 can be adjusted by touching the control screen 45.

[0043] To solve the problem of the running belt rotating at point 4; such as... Figures 1-12 As shown, a drive motor 12 is fixedly connected to one side of the internal support 3, and a guide roller 14 and a guide roller 2 16 are rotatably connected to one side of the internal support 3. A transmission belt 13 is driven to the power output end of the drive motor 12 and one end of the guide roller 14. The running belt 4 is driven to the guide roller 14 and the guide roller 2 16. When the drive motor 12 is working, it can drive the guide roller 14 to rotate through the transmission belt 13, thereby driving the running belt 4 to rotate.

[0044] To solve the problem of adjusting the running angle; such as Figures 1-12 As shown, one end of the buffer plate 49 is rotatably connected to the bottom support plate 5, and multiple silent rubber pads 6 are fixedly connected below the bottom support plate 5. A telescopic rod 7 is fixedly connected to one side of the bottom support plate 5, and a buffer 8 is fixedly connected to the movable end of the telescopic rod 7. A connecting rod 9 is rotatably connected to one end of the buffer plate 49 and the buffer 8.

[0045] When the telescopic rod 7 extends, the buffer plate 49 can be tilted up by the connecting rod 9 to adjust the angle. The buffer 8 is preferably a pneumatic spring, which can be used in conjunction with the silent rubber pad 6 to further achieve the effect of buffering and noise reduction.

[0046] In this embodiment, when the user stands on the running belt 4, the drive motor 12 can be started through the control panel 45 and the running belt 4 can be rotated through the guide roller 14, allowing the user to run. During long-term use, when the lubricating coating between the running belt 4 and the running plate 17 wears down and a dragging feeling occurs when running, when the user steps on the running belt 4 and moves backward, the drive plate 19 will slide backward due to friction. At this time, the inclined platform on one side of the drive plate 19 squeezes the lifting roller 22, causing the lifting rod 21 to move downward. The downward-moving lifting rod 21 will drive the lifting tube 27 to move downward. At this time, the conical plug 30 inside the lifting tube 27 disengages from the limiting groove 29, and the lubricating roller 28 moves downward and one end contacts the inner side of the running belt 4, so that the lubricating oil can be used to lubricate the inner side of the running belt 4 through the lifting tube 27 and the lubricating roller 28, thus solving the dragging feeling caused by increased friction.

[0047] The shock-absorbing pad 48 can work with the magnetic levitation shock-absorbing component 47 to cushion and reduce the impact on the user's knees during running. It can also reduce noise transmission to prevent disturbing other residents. At the same time, the telescopic rod 7 can be extended via the touch control screen 45 to adjust the angle of the running board 17, allowing the user to exercise at different angles.

[0048] Example 2:

[0049] A type of home smart treadmill, such as Figures 1-12 As shown, in order to solve the problem that the loose running belt 4 at the lower end causes the lubricating roller 28 moving downward to not contact the inner side of the running belt 4, this embodiment makes the following improvements based on embodiment 1: A transmission wheel 34 and a transmission gear 35 are rotatably connected to one side of the internal support 3, a transmission wheel 34 is fixedly connected to the transmission gear 35, a drive gear 36 is meshed with one side of the transmission gear 35, a drive gear 36 is fixedly connected to one side of the internal support 3, a transmission belt 15 is rotatably connected to one side of the transmission wheel 34 and the guide roller 14, a guide roller 37 is fixedly connected to one end of the drive gear 36, a squeeze rod 41 is fixedly connected inside the guide roller 37, a telescopic rod 38 is fixedly connected to one side of the internal support 3, and a squeeze sleeve 39 is rotatably connected to the movable end of the telescopic rod 38;

[0050] The guide roller 14 can drive the guide drum 37 to rotate through the transmission wheel 34 and the transmission gear 35. The rotation direction of the guide drum 37 is opposite to that of the guide roller 14, which can make the running belt 4 taut so that the lubrication roller 28 moving from above to the bottom can normally contact the inner side of the running belt 4 and rotate for lubrication.

[0051] To solve the problem of cleaning the surface of the running belt; such as... Figures 1-12 As shown, one end of the extrusion sleeve 39 is rotatably connected to a connecting rod 42, one end of the extrusion rod 41 is rotatably connected to a connecting rod 43, one end of the connecting rod 42 and the connecting rod 43 is rotatably connected to a sliding bracket 44, one end of the sliding bracket 44 is slidably connected to a cleaning brush 40, and one side of the cleaning brush 40 is slidably connected to the guide roller 37.

[0052] When the telescopic rod 38 moves the extrusion sleeve 39 to one side via the control panel 45, the sliding bracket 44 can be moved outward by the linkage 42 and the linkage 33. The outer brush part of the extrusion cleaning brush 40 extends out of the guide roller 37, and the outer side of the running belt 4 can be cleaned when the guide roller 37 rotates.

[0053] To address the issue of reduced user experience due to deformation in the middle of the treadmill belt 4 after prolonged use; such as... Figures 1-12As shown, an electric double-ended lead screw 31 is fixedly connected below the running board 17. A tensioning spring 32 is threadedly connected to the movable end of the electric double-ended lead screw 31. A pressure sensor 33 is fixedly connected to the middle of the tensioning spring 32. When the middle of the running belt 4 does not deform, the middle of the running belt 4 will squeeze the pressure sensor 33. When the pressure sensor 33 receives a decrease in pressure value, it indicates that the middle of the running belt 4 has deformed. At this time, the electric double-ended lead screw 31 rotates, causing the two ends of the tensioning spring 32 to move inward and the middle of the tensioning spring 32 to bend outward to tension the middle of the running belt 4, keeping the running belt 4 taut. The pressure value received by the pressure sensor 33 can be displayed on the control panel 45, and the electric double-ended lead screw 31 can be controlled to work through the control panel 45.

[0054] In this embodiment, when the middle of the running belt 4 deforms after being stepped on for a long time, the pressure sensor 33 receives a decrease in pressure value, indicating that the middle of the running belt 4 has deformed. At this time, the electric double-headed screw 31 rotates, causing the two ends of the tensioning leaf spring 32 to move inward and the middle of the tensioning leaf spring 32 to bend outward to tension the middle of the running belt 4, so that the running belt 4 remains taut.

[0055] Subsequently, guide roller 14 can drive guide roller 37 to rotate through transmission wheel 34 and transmission gear 35. The rotation direction of guide roller 37 is opposite to that of guide roller 14, which can make the running belt 4 taut so that the lubrication roller 28 moving from top to bottom can normally contact the inner side of the running belt 4 and rotate for lubrication.

[0056] The control panel 45 can be used to move the second telescopic rod 38 to one side, and the second connecting rod 42 and the third connecting rod 43 can be used to move the sliding bracket 44 outward. The outer brush part of the squeezing cleaning brush 40 extends out of the guide roller 37, and the outer side of the running belt 4 can be cleaned when the guide roller 37 rotates.

[0057] The above description represents a preferred embodiment of the present invention. The scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, combined with existing technology or common knowledge, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
