Detailed Embodiments

[0022] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0023] Please refer to Figure 1As shown in the figure, a multifunctional walking, running and vibrating fitness structure of the present utility model includes a frame 1, a ring belt 2 rotatably arranged on the frame 1, and a first driving member 3 installed on the frame 1 and used to drive the ring belt 2 to rotate. The frame 1 is welded by metal rod members. According to actual needs, the frame 1 can be made of stainless steel, aluminum alloy or cast iron, and the frame 1 is generally in a cuboid shape.

[0024] A plurality of feet 4 for pressing on an external bearing surface (such as a cement floor or an indoor floor) are installed at the lower end of the frame 1. Preferably, the number of the feet 4 is four, and the four feet 4 are respectively located at the four corners of the frame 1.

[0025] The multifunctional walking, running and vibrating fitness structure further includes two support legs 5 rotatably arranged on the frame 1 and a second driving member 6 for driving the two support legs 5 to open and close. The support legs 5 are located at the lower end of the frame 1. The second driving member 6 drives the two support legs 5 to expand and press against the bearing surface so that the feet 4 are separated from the bearing surface. With the arrangement of the support legs 5, the height of the entire frame 1 is increased, so that it is convenient for the user to lie flat on the ring belt 2 or sit on the ring belt 2. The second driving member 6 drives the two support legs 5 to close and overlap on the lower end of the frame 1 so that the support legs 5 are separated from the bearing surface and the feet 4 are pressed on the bearing surface. That is, at this time, the overall height of the frame 1 is relatively low, and the user can directly stand on the ring belt 2 to walk or run for fitness.

[0026] When walking or running for fitness is needed, the feet 4 are pressed on the bearing surface, the user steps on the ring belt 2, and the first driving member 3 drives the ring belt 2 to rotate continuously. When vibrating fitness is needed, the support legs 5 are pressed against the bearing surface, the user lies on the ring belt 2, and the first driving member 3 drives the ring belt 2 to reciprocate forward and backward to achieve vibrating fitness. The diversity of the user's fitness is realized, and the consumer experience is improved.

[0027] In this embodiment, the support leg 5 has two rollers 7 rotatably arranged at the lower end of the leg frame 8. The two rollers 7 are arranged in parallel, and the rotation axes of the two rollers 7 coincide or are parallel. The two support legs 5 are respectively rotatably arranged at the left and right ends in the length direction of the frame 1. The second driving member 6 is an electric cylinder, a cylinder or an oil cylinder, and the cylinder body and the telescopic rod of the second driving member 6 are respectively rotatably arranged on the leg frames 8 of the two support legs 5.

[0028] During actual use, by extending the telescopic rod of the second driving member 6, the leg frames 8 of the two support legs 5 can be driven to rotate synchronously. Compared with driving the two support legs 5 to rotate by two second driving members 6 respectively, on the one hand, the structural design is simplified, on the other hand, the manufacturing cost is reduced, and at the same time, the consistency of the movement or stop of the two support legs 5 is ensured.

[0029] The frame 1 is provided with two parallel rod bodies. The rod bodies are roughly straight cylindrical bodies. The two rod bodies are respectively used in cooperation with two leg frames 8. That is, the two leg frames 8 are respectively rotatably arranged on the two rod bodies. Preferably, the leg frame 8 is equipped with rolling bearings sleeved on the outer sides of the rod bodies. After the second driving member 6 drives the two support legs 5 to extend, the two support legs 5 are roughly in a V-shaped. With the rollers 7 at the lower ends of the two support legs 5 pressing on the bearing surface. By means of the arrangement of the rollers 7, it is avoided that the support legs 5 made of metal damage the bearing surface, and at the same time, it is convenient to move the position where the frame 1 is located. In this embodiment, the rollers 7 are made of silica gel. By means of the softness characteristic of the silica gel, when the user performs vibration fitness, the vibration impact of the frame 1 on the bearing surface via the support legs 5 is reduced, and at the same time, the vibration noise is reduced.

[0030] The leg frame 8 has two parallel legs and a cross bar connecting the middle parts of the two legs. The legs are roughly straight bars. The upper ends of the two legs of the same leg frame 8 are respectively rotatably arranged on the same rod body. The two rollers 7 are respectively arranged at the lower ends of the two legs. The legs are provided with a braking member 9 for braking the rollers 7. After the frame 1 presses on the required position on the bearing surface via the support legs 5, the braking member 9 brakes the rollers 7, so as to avoid the frame 1 moving around due to accidental collision, and ensure that the frame 1 is firmly positioned at the required position.

[0031] In this embodiment, two stop portions 10 are installed on the frame 1. The two support legs 5 are located between the two stop portions 10. The stop portion 10 is provided with a buffer rubber pad 11 for abutting and stopping the support leg 5 to prevent the two support legs 5 from opening too much. After the second driving member 6 drives the two support legs 5 to extend to the required predetermined angle, the buffer rubber pad 11 of the stop portion 10 abuts on the support leg 5. By means of the soft characteristic of the buffer rubber pad 11, the vibration impact transmitted from the support leg 5 to the stop portion 10 during vibration fitness is absorbed, and the damage and noise caused by the frequent collision of the stop portion 10 and the support leg 5 are avoided. Preferably, each stop portion 10 includes a cross bar and two buffer rubber pads 11 detachably connected to the cross bar. The two buffer rubber pads 11 of the same cross bar are used to respectively abut the two legs of the same support leg 5. According to actual needs, the buffer rubber pad 11 can adopt a U-shaped structure, and the U-shaped structure is clamped and sleeved on the outer side of the cross bar, which is convenient for disassembling and assembling the buffer rubber pad 11.

[0032] The support leg 4 has a fixing rod 12 detachably connected to the frame 1 and a pressing disk 13 disposed at the lower end of the fixing rod 12 and used for pressing on the bearing surface. The fixing rod 12 is made of metal. For example, the fixing rod 12 is a threaded post. The pressing disk 13 includes a metal spring 14 and an elastic plastic part 15 injection-molded and coated on the outer side of the metal spring 14. The metal spring 14 is made of spring steel, and the central axis of the metal spring 14 coincides with or is parallel to the central axis of the fixing rod 12. In this embodiment, by virtue of the rigidity and elastic characteristics of the metal spring 14 and in cooperation with the flexible characteristics of the elastic plastic part 15, it is ensured that the pressing disk 13 has sufficient rigidity and elasticity. During actual use, when the frame 1 bears the user, there is a large pressure. If the rigidity is too large, the shock absorption effect is not good. If the rigidity is low and the elasticity is large, the height of the product will drop significantly. With the combination of the metal spring 14 and the elastic plastic part 15, while maintaining good elasticity, it has a certain sense, avoiding the problem of large drop amplitude during vibration and at the same time preventing the user's knees from being damaged due to secondary stress.

[0033] In this embodiment, two rotating rollers 16 are respectively disposed at both ends of the frame 1 along the length direction. The two rollers 16 are arranged in parallel. The endless belt 2 is sleeved on the outer sides of the two rollers 16, and the first driving member 3 is used to drive at least one roller 16 to rotate. According to actual needs, the first driving member 3 can drive the roller 16 to rotate continuously so that the endless belt 2 rotates continuously, or the first driving member 3 can also drive the roller 16 to rotate forward and backward to realize the vibration of the endless belt 2.

[0034] In this embodiment, the endless belt 2 also has a soft magnetic sheet, which extends along the length direction and width direction of the endless belt 2. During actual manufacturing, the soft magnetic sheet is first configured, and then the strip material is formed by coating on the outer side of the soft magnetic sheet. Preferably, the soft magnetic sheet is a neodymium iron boron magnetic sheet (i.e., a powerful magnetic sheet). By virtue of the magnetic field characteristics of the soft magnetic sheet, when the user exercises on the endless belt 2, the magnetic field of the soft magnetic sheet acts on the user's body, improving blood circulation, increasing the blood oxygenation level, and thus promoting physical health. Stimulating the nerve endings of the human body, releasing natural pain-relieving substances inside the body, and relieving pain caused by different reasons. Stimulating body cells to present a more active state, helping cell regeneration and repairing damaged tissues. Reducing the muscle inflammatory response and alleviating the problem of muscle soreness. Stimulating the acupoints on the user's soles and improving blood circulation in the feet. At the same time, neutralizing the acidic substances generated by sweat, which has an improvement effect on problems such as foot sweat, beriberi, and foot odor.

[0035] On the frame 1, there is a support plate 17 located between two rollers 16. The annular belt 2 is wound around the support plate 17. The support plate 17 is a metal plate and is used to support the upper part of the annular belt 2. With the arrangement of the support plate 17, the strength of the annular belt 2 to bear the user is improved. When the user walks, runs, lies flat, lies on the side or sits on the annular belt 2, the support plate 17 is used to support the user, preventing the user from crushing the annular belt 2 and extending its service life.

[0036] On the frame 1, a plurality of soft rubber pads 18 and a plurality of positioning columns 19 respectively passing through the plurality of soft rubber pads 18 are installed. The support plate 17 is pressed on the plurality of soft rubber pads 18, and the support plate 17 is provided with a plurality of positioning holes respectively accommodating the plurality of positioning columns 19. The soft rubber pad 18 can be a silica gel pad or a spring coil. With the soft buffering characteristic of the soft rubber pad 18, the support plate 17 is buffered. When the user walks or runs on the support plate 17, the soft rubber pad 18 buffers the impact force applied by the support plate 17 to the frame 1, improving the consumer experience.

[0037] The first driving member 3 has a first motor 20 installed on the frame 1, a first pulley arranged on the output shaft of the first motor 20, a second pulley arranged on the roller 16, and a conveyor belt 21 wound around the outside of the first pulley and the second pulley. The radius of the first pulley is smaller than the radius of the second pulley. The first pulley and the second pulley form a speed reducer, reducing the rotation speed of the first motor 20 and increasing the output torque of the first motor 20 to ensure that the first motor 20 has sufficient output power to drive the annular belt 2 to operate.

[0038] The first motor 20 has a stator fixedly arranged on the frame 1 and a rotor rotatably arranged inside the stator. The stator has a cylinder body 22 accommodating the rotor, a first cover 23 and a second cover 24 respectively installed at both ends of the cylinder body 22. The cover has a ventilation hole 25 passing through the cover and exposing the rotor. Preferably, the number of ventilation holes 25 on each cover is multiple, and the multiple ventilation holes 25 are arranged in an annular array around the central axis of the cover.

[0039] The rotor has a main shaft passing through the first cover 23, and the first pulley is installed on the main shaft. The first pulley has a pulley part 26 cooperating with the conveyor belt 21, a disc part 27 arranged on the pulley part 26, and a plurality of arc-shaped blades arranged on the disc part 27. The radius of the pulley part 26 is smaller than the radius of the disc part 27, the radius of the disc part 27 is the same as the radius of the cover, the disc part 27 is arranged parallel to the first cover 23, the first cover 23 is located between the disc part 27 and the second cover 24, and a clearance 28 is formed between the first pulley and the first cover 23.

[0040] During the actual use of the first motor 20, heat dissipation for the first motor 20 is required. Especially when the first motor 20 drives the endless belt 2 to rotate forward and backward with vibration, the first motor 20 will accumulate a large amount of heat. If this heat cannot be dissipated in time, the coil of the first motor 20 will be damaged due to excessive temperature. With the structural arrangement of the arc-shaped blades of the first pulley, when the stator drives the first pulley to rotate, the arc-shaped blades of the first pulley rotate, driving air to flow through the clearance space 28, the ventilation holes 25, and the clearance between the stator and the rotor, thereby achieving rapid heat dissipation for the first motor 20.

[0041] Lifting frames 29 are provided at both ends of the frame 1, and a plurality of support feet 4 are respectively provided at the lower ends of the lifting frames 29; the lifting frame 29 includes a carrier frame 30, a common shaft 31 rotatably provided on the carrier frame 30, a second motor for driving the common shaft 31 to rotate, two threaded rods respectively cooperating with both ends of the common shaft 31 and arranged in parallel, two threaded barrels 32 respectively screwed and cooperating with the two threaded rods, and a cross beam 33 connecting the two threaded barrels 32 and fixed to the frame 1. The second motor drives the common shaft 31 to rotate the two threaded rods, and the support feet 4 are provided at the lower end of the carrier frame 30.

[0042] During the actual use of the frame 1, people of different heights require different heights of the endless belt 2. With the arrangement of the lifting frame 29, according to the height requirements of different users, the user can adjust the second motor to drive the common shaft 31 to rotate, thereby achieving the raising or lowering of the threaded barrel 32. When the threaded barrel 32 moves up and down, it can drive the frame 1 to move up and down via the cross beam 33, meeting the actual needs of users of different heights.

[0043] Certainly, taking the two ends in the length direction of the frame 1 as the first end and the second end, for actual users, the adjustable heights of the two lifting frames 29 can be different, that is, the first end of the frame 1 is located above the second end. In this way, when the user is walking or running for fitness, the needs of going uphill or downhill can be achieved. At the same time, when the user lies on the frame 1, the posture of having the head higher than the feet or the head lower than the feet can also be realized.

[0044] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
