Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and in particular to an integrated treadmill for fitness and a fitness method thereof. Background Art

[0002] As people's health awareness continues to improve, the fitness equipment market has developed rapidly. As a common aerobic fitness equipment, treadmills are deeply loved by fitness enthusiasts. Traditional treadmills mainly provide flat running functions. Although they can meet users' aerobic exercise needs to a certain extent, such as improving cardiopulmonary function and consuming calories, their functions are relatively single. Long-term use can easily make users feel bored, and the exercise of muscle groups in specific parts of the body is not comprehensive enough.

[0003] In the field of fitness training, stair climbing is considered an efficient way of exercise. It can effectively exercise the leg muscles, including the quadriceps on the front of the thigh, the hamstrings on the back, and the buttocks muscles, and it also has a significant effect on improving cardiopulmonary function and body coordination. However, in real life scenarios, due to venue and environmental limitations, not everyone can easily perform stair climbing exercises. For example, outdoor stair exercises are difficult to achieve when living in a low-rise apartment or in bad weather.

[0004] In order to overcome the problem of traditional treadmills having a single function and stair climbing exercise being limited by the venue, some treadmills with slope adjustment function have gradually appeared on the market. These treadmills simulate climbing exercise by changing the inclination angle of the running belt, which increases the diversity of fitness to a certain extent.

[0005] However, existing fitness equipment with climbing functions has obvious defects. When the user performs a simple climbing action, the sole of the foot is forced to tilt when it contacts the slope because the slope is in a fixed tilt state, causing the entire foot and leg to be in a tilted posture. During long-term exercise, the ankle joint needs to continue to bear the unbalanced pressure from the body weight in the tilted direction. This unbalanced force condition violates the principles of motion mechanics under the normal physiological structure of the human body. The ligaments, muscles, and articular cartilage around the ankle joint are in a stress state of excessive stretching or compression for a long time. With the accumulation of exercise time, it is very easy to cause ankle fatigue, pain, and even chronic injuries, such as ankle sprains, ligament strains, and joint wear. This not only seriously affects the user's fitness effect and sports experience, but may also cause the user to interrupt the fitness plan due to pain, increase rehabilitation costs and time, and thus limit the wide application and further development of such simple climbing fitness equipment in the fitness market.

[0006] In view of the above problems, we propose an integrated treadmill for fitness and a method thereof. Summary of the invention

[0041] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0042] See also Figures 1 to 13 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0043] The present invention provides a technical solution: an integrated treadmill for fitness, comprising a base 1, a vertical plate 2, an arc guide rail 3, a connecting shaft 4, a mounting plate 5, a first rotating shaft 6, a second rotating shaft 7, a first sprocket 8, a second sprocket 9, a chain 10, a rectangular collapse block 11, a stabilizing mechanism 12, an angle adjustment mechanism 13, a protective cover 14 and other components.

[0044] First, two symmetrically arranged vertical plates 2 and two arc-shaped guide rails 3 are fixedly connected to the top surface of the base 1. The side walls of the two vertical plates 2 are used to rotate through two connecting shafts 4, and the connecting shafts 4 play a key role in supporting and rotating the subsequent components. The end of the connecting shaft 4 away from the vertical plate 2 is fixedly connected to the mounting plate 5, so that the mounting plate 5 can rotate around the connecting shaft 4 at a certain angle.

[0045] Between the two mounting plates 5, the first rotating shaft 6 is rotatably connected to the side wall of the mounting plate 5 close to the connecting shaft 4, and the second rotating shaft 7 is rotatably connected to the side wall of the mounting plate 5 away from the first rotating shaft 6. Two symmetrically arranged first sprockets 8 are fixedly connected to the outer wall of the first rotating shaft 6, and two symmetrically arranged second sprockets 9 are fixedly connected to the outer wall of the second rotating shaft 7. The chain 10 is meshed with the first sprocket 8 and the second sprocket 9, and the chain 10 is driven to circulate through the rotation of the sprockets. A plurality of rectangular collapse blocks 11 are rotatably connected to the side walls of the chain 10 through pins, and a stabilizing mechanism 12 is installed on the rectangular collapse blocks 11, which is used to tightly fit with adjacent rectangular collapse blocks 11 under different operating conditions to ensure the safety of the user and the stability of the movement.

[0046] An angle adjustment mechanism 13 is installed at one end of the two mounting plates 5 away from the first rotating shaft 6, which engages with the outer wall of the arc guide rail 3 for transmission. Through precise mechanical structure design, the angle of the mounting plate 5 can be flexibly adjusted, so that several rectangular blocks 11 can present different states, such as horizontal arrangement or stair-step shape, to meet the user's diverse fitness needs.

[0047] The protective cover 14 plays a role of protection and auxiliary support for the operation of the entire treadmill. It includes two side panels 1401 fixedly mounted on the side walls of the two mounting plates 5. The top of the side panels 1401 is horizontally folded, and its bottom surface is slidably connected to the top surface of the chain 10. This design can not only prevent users from accidentally contacting the chain 10 and other moving parts, but also play a certain guiding and supporting role in the operation of the chain 10. The two ends of the two side panels 1401 are fixedly connected to two arc covers 1402, and the chain 10 and the rectangular collapse block 11 at the first sprocket 8 and the second sprocket 9 are located inside the two arc covers 1402, further enhancing the protection effect of the key moving parts.

[0048] In order to better support the chain 10, the side wall of the side plate 1401 is fixedly connected with an L-shaped plate 1403, and the top surface of the L-shaped plate 1403 is slidably connected to the bottom surface above the chain 10, ensuring that the chain 10 always maintains a stable running track during long-term operation, reducing the noise and wear caused by the shaking of the chain 10, and extending the service life of the equipment.

[0049] A plurality of spherical cavities 1101 arranged horizontally are provided inside the rectangular collapse block 11, and a copper ball 1102 is provided on the inner wall of the spherical cavity 1101 to play the role of counterweight. In the design of the rectangular collapse block 11, the plurality of spherical cavities 1101 arranged horizontally and the copper ball 1102 inside thereof play a key role. When the treadmill is in a stationary state or the chain 10 is running slowly, since the copper ball 1102 can roll freely in the spherical cavity 1101, under the action of gravity, the copper ball 1102 will tend to be at the lowest position of the spherical cavity 1101, thereby changing the center of gravity distribution of the rectangular collapse block 11. This center of gravity adjustment is similar to the principle of a tumbler, so that the rectangular collapse block 11 can automatically tend to maintain a vertical state, thereby ensuring that its top surface always maintains a horizontal state.

[0050] During the operation of the treadmill, for example, when the chain 10 drives the rectangular collapse block 11 to rise or fall, even if it is disturbed by a certain external force or affected by the inertia of movement, the copper ball 1102 will roll and redistribute accordingly in the spherical cavity 1101, and continue to fine-tune the center of gravity of the rectangular collapse block 11 to resist the tendency of the external force to deviate from the vertical state, and ensure that the top surface of the rectangular collapse block 11 is as close to the horizontal as possible. This feature is very important for users to perform fitness activities on the rectangular collapse block 11, such as running or climbing stairs to simulate exercise. It provides users with a relatively stable and flat tread surface, reduces the probability of accidents such as slipping or spraining caused by the tilt of the rectangular collapse block 11, and greatly improves the safety and comfort during fitness.

[0051] The side wall of the rectangular collapse block 11 is provided with a plurality of evenly arranged rectangular grooves 1103 and the other side wall is provided with a storage groove 1104. The top surface is provided with a plurality of evenly arranged guide grooves 1105. The inner wall of the guide groove 1105 is fixedly connected with two symmetrically arranged first guide blocks 1106.

[0052] The specific working principle of the stabilizing mechanism 12 is as follows: the electric push rod 1201 is fixedly installed in the installation groove provided on the inner wall of the storage groove 1104. When a stable connection operation is required, the telescopic end of the electric push rod 1201 pushes the rectangular plate 1202. The inner wall of the U-shaped groove 1203 at the top of the rectangular plate 1202 is fixedly connected with two symmetrically arranged second guide blocks 1212, and a strip block 1204 is slidably connected in the U-shaped groove 1203, and two strip grooves 1205 are provided on the two side walls of the strip block 1204. When the electric push rod 1201 pushes the rectangular plate 1202, the inner wall of the guide groove 1105 is slidably connected with the outer wall of the strip block 1204, and the outer walls of the first guide block 1106 and the second guide block 1212 are slidably connected with the inner wall of the strip groove 1205, respectively, so as to ensure that the strip block 1204 can accurately enter the corresponding slot of the adjacent rectangular collapse block 11.

[0053] The side wall of the rectangular plate 1202 is fixedly connected with a plurality of rectangular blocks 1206, and a transmission shaft 1207 is rotatably connected to the side wall of the rectangular block 1206. A plurality of first gears 1208 are fixedly sleeved on the outer wall of the transmission shaft 1207. Every two rectangular blocks 1206 form a group, and a lifting plate 1209 is slidably connected to the side wall between the two rectangular blocks 1206 in each group, and teeth meshing with the first gears 1208 are provided on the side wall of the lifting plate 1209. When the bar block 1204 enters the slot at different positions, such as when it is tilted on a steep slope, the bar block 1204 presses against the side wall below the rectangular groove 1103 and slides in the U-shaped groove 1203, and is transmitted to the second gear 1211 through the teeth at the bottom of the bar block 1204. The transmission shaft 1207 drives the first gear 1208, and the first gear 1208 cooperates with the teeth of the lifting plate 1209, so that the lifting plate 1209 rises, the electromagnet 1210 rises, and the side wall at the top of the rectangular plate 1202 presses against the side wall at the bottom of the rectangular collapse block 11. The rise of the electromagnet 1210 increases the distance between the electromagnet 1210 and the rectangular plate 1202, thereby increasing the fit span of the electromagnet 1210 and the rectangular plate 1202 relative to the rectangular collapse block 11 in front of them, thereby improving stability when tilting on a steep slope.

[0054] The side wall of the lifting plate 1209 located just above the rectangular plate 1202 is fixedly connected with an electromagnet 1210, and the side wall of the rectangular collapse block 11 is inlaid with a bar iron block 1107 that is magnetically attracted to the electromagnet 1210. When the electromagnet 1210 is energized, it can adsorb the bar iron block 1107, further enhancing the stability of the connection between the rectangular collapse blocks 11. The second gear 1211 fixedly sleeved on the outer wall of the transmission shaft 1207 is meshed with the teeth opened at the bottom of the bar block 1204, and the outer wall of the transmission shaft 1207 located between the second gear 1211 and the rectangular block 1206 is sleeved with a torsion spring 1213, and the two ends of the torsion spring 1213 are fixedly connected to the second gear 1211 and the side wall of the rectangular block 1206 respectively. The torsion force of the torsion spring 1213 is applied to the second gear 1211, and then acts on the first gear 1208 and the lifting plate 1209 through the transmission shaft 1207 to engage the transmission, so that the bottom of the electromagnet 1210 is pressed against the bottom of the U-shaped groove 1203, maintaining the stability and compactness of the stabilizing mechanism 12 in the initial state or when no special adjustment is required.

[0055] The angle adjustment mechanism 13 is composed of two symmetrically arranged connecting plates 1301. The side wall between the two connecting plates 1301 is rotatably connected to two rollers 1302 through a pin shaft. The outer wall of the roller 1302 is in rolling connection with the inner wall of the arc guide rail 3. This rolling connection mode can reduce friction and make the angle adjustment process smoother. The side wall of the connecting plate 1301 is fixedly installed with a first motor 1303. The outer wall of the output shaft of the first motor 1303 is fixedly sleeved with a third gear 1304 arranged between the two connecting plates 1301. The outer wall of the arc guide rail 3 is provided with teeth meshing with the third gear 1304. When the first motor 1303 drives the third gear 1304 to rotate, the third gear 1304 moves along the teeth of the outer wall of the arc guide rail 3. Since the shape and position of the arc guide rail 3 are fixed, the connecting plate 1301 is driven to move along the arc guide rail 3, and then the mounting plate 5 is rotated with the connecting shaft 4 as the axis, so as to achieve the angle adjustment of the chain 10 and the rectangular collapse block 11. The side walls of the arc guide rail 3 and the side walls between the two connecting plates 1301 are slidably connected, further ensuring stability and accuracy during angle adjustment. The side walls between the two connecting plates 1301 are fixedly connected to the side walls of the mounting plate 5, ensuring effective force transmission and coordinated movement of the overall structure.

[0056] In addition, the side wall of the connecting plate 1301 is fixedly connected with a second motor 19, and the output end of the second motor 19 is axially connected to one end of the second rotating shaft 7, so as to drive the circulation of the chain 10. The inner wall of the arc guide rail 3 is fixedly connected with an arc rod 15, which can be used as a handrail to facilitate the user to maintain body balance and stability when performing operations such as climbing stairs. The arc centers of the arc guide rail 3 and the arc rod 15 coincide with the axis center of the connecting shaft 4, and the arc rod 15 can move through the gap between the two connecting plates 1301. This design makes the overall structure more compact and reasonable, and improves the aesthetics and practicality of the equipment while meeting the functional requirements.

[0057] Several infrared sensors 16 are fixedly installed on the side wall of the chain 10, and are located on the outer wall of the connecting pin of the rectangular collapse block 11 and the chain 10. The inner walls of the two arc-shaped covers 1402 are fixedly installed with a front infrared emitter 17 and a rear infrared emitter 18. During the operation of the treadmill, the infrared sensor 16 is used to detect the infrared rays emitted by the front infrared emitter 17 and the rear infrared emitter 18. When the infrared sensor 16 detects the infrared rays emitted by the front infrared emitter 17, the controller will control the electric push rod 1201 and the electromagnet 1210 and other components in the rectangular collapse block 11 where the infrared sensor 16 is located to perform corresponding actions according to the preset program, such as pushing the rectangular plate 1202, making the bar block 1204 enter the corresponding slot, and energizing the electromagnet 1210, etc., to achieve a stable connection between the rectangular collapse blocks 11. When the infrared sensor 16 detects the infrared rays emitted by the rear infrared emitter 18, the controller controls the electromagnet 1210 in the rectangular collapse block 11 where the infrared sensor 16 is located to be powered off, and the electric push rod 1201 pulls the rectangular plate 1202 back into the receiving groove 1104, releasing the connection between the rectangular collapse blocks 11 so as to perform the next cycle of movement. Through the cooperation of this precise sensor and control system, the treadmill is automatically controlled and operated stably in different operating states, providing users with a more convenient, safe and efficient fitness experience.

[0058] The integrated treadmill for fitness also includes a controller;

[0059] A method for using an integrated treadmill for fitness includes the following steps:

[0060] S1, the mounting plate 5 is kept in a horizontal state, and the top surfaces of the plurality of rectangular collapse blocks 11 located between the two mounting plates 5 are located in the same horizontal plane;

[0061] During fitness, the second motor 19 drives the second rotating shaft 7 to rotate, and then the first sprocket 8 and the second sprocket 9 rotate, driving the chain 10 to run, and a plurality of rectangular collapse blocks 11 follow the cycle. When the rectangular collapse block 11 runs to the upper side, one of the infrared sensors 16 passes through the front infrared transmitter 17. The infrared sensor 16 detects the infrared ray emitted by the front infrared transmitter 17, and the controller controls the electric push rod 1201 in the rectangular collapse block 11 where the infrared sensor 16 is located to push the rectangular plate 1202 forward, and the bar in the rectangular collapse block 11 where the infrared sensor 16 is located is The strip block 1204 enters the guide groove 1105 of the rectangular block 11 in front of it, and the strip block 1204 connects the gap between the two adjacent rectangular blocks 11. The rectangular plate 1202 presses against the side wall of the rectangular block 11 in front of it. At the same time, the controller controls the electromagnet 1210 in the rectangular block 11 to be energized to generate magnetism, so that the electromagnet 1210 absorbs the strip iron block 1107 in front of it; thereby, the stabilizing mechanism 12 and the rectangular block 11 in front of it are pressed against each other, and the fitness personnel can stand on the several rectangular blocks 11 on the same horizontal plane above to run and exercise;

[0062] When one of the infrared sensors 16 passes by the rear infrared emitter 18, the infrared sensor 16 detects the infrared emitted by the rear infrared emitter 18, and the controller controls the electromagnet 1210 in the rectangular collapse block 11 where the infrared sensor 16 is located to be powered off, and the magnetism of the electromagnet 1210 disappears. At the same time, the controller controls the electric push rod 1201 in the rectangular collapse block 11 where the infrared sensor 16 is located to pull the rectangular plate 1202 back into the receiving groove 1104;

[0063] S2, the first motor 1303 drives the third gear 1304 to rotate, the third gear 1304 cooperates with the teeth on the outer wall of the arc guide rail 3, and the third gear 1304 moves upward along the teeth, so that the angle adjustment mechanism 13 moves upward, driving the mounting plate 5 to rotate with the connecting shaft 4 as the axis, so that the chain 10 is inclined, and the plurality of rectangular collapsed blocks 11 on the chain 10 are in the shape of stairs, such as Fig.11 ;

[0064] The steps include normal slope incline and steep slope incline;

[0065] like Fig.12During the operation of the ordinary slope tilting chain 10, one of the infrared sensors 16 passes through the front infrared emitter 17, and the electric push rod 1201 in the rectangular collapse block 11 where the infrared sensor 16 is located pushes the rectangular plate 1202 forward, and the bar block 1204 in the rectangular collapse block 11 where the infrared sensor 16 is located enters the rectangular groove 1103 of the rectangular collapse block 11 in front of it, and the electromagnet 1210 in the rectangular collapse block 11 is energized to generate magnetism, and then the electromagnet 1210 absorbs the bar iron block 1107 in front of it; thereby achieving the tight fit between the stabilizing mechanism 12 and the rectangular collapse block 11 in front of it;

[0066] like Fig.13 During the operation of the steep slope inclined chain 10, one of the infrared sensors 16 passes the front infrared emitter 17, and the electric push rod 1201 in the rectangular collapse block 11 where the infrared sensor 16 is located pushes the rectangular plate 1202 forward, and the bar block 1204 in the rectangular collapse block 11 where the infrared sensor 16 is located is pressed against the side wall below the rectangular groove 1103 of the rectangular collapse block 11 in front of it. During the pressing process, the bar block 1204 slides in the U-shaped groove 1203 and is transmitted to the second gear 1211 through the teeth at the bottom of the bar block 1204, then the transmission shaft 120 7 drives the first gear 1208, and the first gear 1208 cooperates with the teeth of the lifting plate 1209, so that the lifting plate 1209 rises, the electromagnet 1210 rises, and the side wall of the top of the rectangular plate 1202 is pressed against the side wall of the bottom of the rectangular collapse block 11. The rise of the electromagnet 1210 increases the distance between the electromagnet 1210 and the rectangular plate 1202, thereby increasing the fitting span of the electromagnet 1210 and the rectangular plate 1202 relative to the rectangular collapse block 11 in front of them, thereby improving the stability when the slope is steep; at the same time, the electromagnet 1210 is energized to adsorb the bar iron block 1107;

[0067] The angle adjustment mechanism 13 is meshed with the outer wall of the arc guide rail 3 to adjust the angle of the mounting plate 5. The plurality of rectangular blocks 11 are in the shape of stairs. The upper stabilizing mechanism 12 is tightly fitted with the adjacent rectangular blocks 11. The fitness person can stand on the stepped rectangular blocks 11 to perform stair climbing exercises.
