[0027] In the embodiment of the present application, the running platform 5 is manufactured by integral molding. The integrally molded running platform has a lower cost, a higher assembly efficiency, easier maintenance, and a lower failure rate. Preferably, engineering plastics (e.g., polycarbonate, nylon, ABS, etc.) or carbon fiber composite materials can be used as the material of the running platform to reduce the weight of the running platform. More specifically, the composite material may be a material formed by compounding polypropylene (PP) with 10-30% glass fiber (GF), that is, 10%-30% (e.g., 10%, 15, 20%, 25% or 30%) glass fiber (GF) is added to the polypropylene (PP) material to perform modified reinforcement. The treadmill according to the present application is lighter, smaller, easier to store, and more suitable for home use.

[0028] In one possible embodiment, a wear plate 6 is provided between the upper side of the base part 51 of the running platform 5 and the covering running belt 7. The wear plate 6 enhances the flatness of the moving contact surface, and the wear plate 6 provides support and cushioning between the running belt 7 and the running platform 5, improving the durability of the entire treadmill.

[0029] In one possible embodiment, a receiving groove is provided in the carriage 5, and the servo motor 2 is arranged in the receiving groove.

[0030] In one possible embodiment, the support includes a left support and a right support, and the base 51 connects the left support and the right support to form an I-shaped support structure. Fig. 3 is a perspective view of a running platform according to an embodiment of the present application. As shown in Fig. 3, the integrally molded running platform includes a base 51 and support parts 52 on the left and right sides.

[0031] In such an example, the accommodating groove may be provided within the base portion of the running platform 5, and more preferably, may be provided on the inside of the left support portion of the running platform 5 or on the inside of the right support portion of the running platform 5.

[0032] In one possible embodiment, a first receiving groove and a second receiving groove are provided in the left support part and the right support part of the running platform 5, respectively, and the servo motor 2 is disposed in the first receiving groove. The treadmill further includes a controller 3, which is provided in the second receiving groove and is electrically connected to the servo motor 2 to drive the output torque of the servo motor 2.

[0033] The servo motor 2 has a feature of being compact, and can be flexibly installed inside the running platform 5, and there is no need to provide additional storage space for the motor, which can effectively save space. For example, the servo motor 2 is installed in a storage groove in the left support part of the running platform 5, and the controller 3 is installed in a storage groove in the right support part of the running platform 5. For example, the servo motor 2 and the pulley connected thereto are disposed in the storage groove in the left support part of the running platform 5, and the controller 3 is installed in the storage groove in the right support part of the running platform 5. Naturally, logically, in consideration of the balance of the weight, beauty, functional connection, etc., each member of the treadmill drive device can be distributed or concentrated at any position in the running platform 5, and this application is not limited thereto. The servo motor 2 and the speed adjustment transmission mechanism 4 may be further installed on the first support plate 2a, and the controller 3 may be further installed on the second support plate 3a.

[0034] Fig. 4 is a schematic perspective view of the main components of a treadmill according to an embodiment of the present application after disassembly. As shown in Fig. 4, the treadmill includes a treadmill roller 1, a servo motor 2, a controller 3, a running platform 5, a wear-resistant plate 6, and a running belt 7 that covers the treadmill roller 1.

[0035] In one possible embodiment, the integrally molded running platform 5 has a lattice structure inside, which provides excellent stress performance, rigidity and vibration suppression ability. Preferably, the size of the lattice and the distribution of the connection points in the lattice structure can be set according to the overall size of the running platform and the load-bearing requirements, and the present application is not specifically limited thereto. The overall size of the running platform may use the size of a general running platform, or according to the demand for miniaturization of the treadmill, a running platform smaller than the general size may be selected to meet the size requirements of the treadmill.

[0036] The treadmill according to the embodiment of the present application uses a running platform with a one-piece structure, and during its manufacture, a seamless connection is realized through precise molds and processes, which can avoid the seam and loosening problems caused by traditional spliced ​​structures. Such seamless connection not only improves the stability of the running platform, but also reduces noise and vibration during exercise. In addition, the running platform with a one-piece structure usually uses a streamlined design. Such a design not only makes the running platform look more stylish and advanced, but also helps reduce wind resistance and noise.

[0037] Furthermore, there is no need to provide additional space for arranging the driving parts, and the servo motor and controller can be flexibly installed in any accommodation groove in the integrally molded running base, thereby greatly saving space and ensuring the compactness and beauty of the entire treadmill structure, thereby realizing a lightweight and easy-to-port home treadmill structure.

[0038] 5 is a schematic perspective view of each component of a treadmill according to an embodiment of the present application after disassembly. Various preferred components of the treadmill in various possible embodiments will be described below with reference to FIG.

[0039] In one possible embodiment, the treadmill roller 1 includes a front roller 1a and a rear roller 1b, both of which are provided with protective caps 8 on the outside of their mounting points on the running platform 5 at both ends of the front roller 1a and at both ends of the rear roller 1b.

[0040] In one possible embodiment, the treadmill roller 1 is provided with a strainer 101 for adjusting the tension of the running belt 7 covering the treadmill roller. Preferably, the strainer 101 is an adjustment bolt, and one adjustment bolt is provided at each end of the treadmill roller (1a and 1b). The adjustment bolts of the treadmill rollers (1a and 1b) rotate to drive the rollers to move back and forth, thereby adjusting the tension of the running belt 7, thereby keeping the running belt 7 in a stable operation and reducing slippage and wear.

[0041] In one possible embodiment, the treadmill further includes at least one of a stiffening plate, a dust cap, and a pad.

[0042] At least one reinforcing plate 9 is provided between the running platform 5 and the wear plate 6, and is used for support and vibration damping.

[0043] A dust cap 201 is provided on the servo motor 2 of the drive unit of the treadmill. At least one pad 10 is provided under the running platform 5, and the pad 10 is used for anti-slip and sound insulation.

[0044] In the schematic diagram of another treadmill according to an embodiment of the present application, the structure of the running platform is not shown. As shown in FIG. 6, taking the front roller 1a as an example, protective caps 8 are attached to both ends of the front roller 1a, and the front roller 1a further has a strainer 101 provided within the protective cap 8, and preferably the strainer 101 is an adjustment bolt.

[0045] As shown in Fig. 6, the servo motor 2 and the speed adjusting transmission mechanism 4 are provided on one side of the running belt 7, and as shown in Fig. 7, the servo motor 2 and the speed adjusting transmission mechanism 4 are fitted into the accommodation groove of the support part 52 on one side of the running platform 5. The controller 3 is provided on the other side of the running belt 7, and fitted into the accommodation groove of the support part 52 on the other side of the running platform 5.

[0046] A wear-resistant plate 6 is further provided between the running belt 7 and the running table 5, and a plurality of reinforcing plates 9 are provided below the wear-resistant plate 6, and the plurality of reinforcing plates 9 are fitted into the upper interior of the running table 5. Specifically, as shown in Figures 8 to 9, the upper surface of the running table 5 is provided with grooves 5a in the same number as the reinforcing plates 9, and the plurality of reinforcing plates 9 are fitted into a corresponding number of grooves 5a, thereby achieving support reinforcement and vibration damping effects for the main body of the running table 5.

[0047] The pad 10 is provided under the running platform 5, specifically, as shown in FIG. 10, the pad 10 is provided under the support part 52 of the running platform 5 and is used for anti-slip and soundproofing, and the remote controller 11 can send commands to the controller 3 to control the mode of the treadmill.

[0048] In another embodiment, the treadmill further supports a horizontal rhythm function. The driving device of the treadmill, which is composed of the treadmill roller 1, the servo motor 2, and the controller 3, realizes the horizontal rhythm function. Specifically, the controller 3 controls the output torque of the servo motor 2, so that the treadmill roller 1 drives the running belt 7 to oscillate and rotate in one direction, or to oscillate horizontally during the process of rotating in one direction.

[0049] The servo motor 2 is provided with an internal and / or external encoder and is connected to the controller 3 via the encoder. The transmission shaft of the servo motor 2 is connected to the treadmill roller 1 so as to be capable of transmitting power.

[0050] In the present embodiment, the controller 3 provides electrical control of the entire device.

[0051] In the embodiment of the present application, various drive modes can be realized by performing bidirectional alternating changes and unidirectional changes on the rotation angle of the servo motor 2. A description will now be given of the various drive modes.

[0052] (Drive mode A, horizontal vibration) Specifically, when the rotation angle of the servo motor 2 alternates in both directions, the servo motor 2 drives the treadmill roller 1 to vibrate horizontally. The bidirectional alternating change of the rotation angle of the servo motor 2 refers to rotating the rotation angle forward at a certain angle and then reversed at a certain angle to realize a motion trajectory of reciprocating rotation in two opposite directions, and when the forward and reverse speeds reach a certain value, the treadmill roller 1 is driven to achieve the effect of horizontal vibration. Regarding the user's experience, the horizontal vibration can achieve the experience effect of a vibration massage, so that the driven fitness equipment (e.g., treadmills and running machines) provides basic functions and achieves a massage effect.

[0053] In one possible embodiment, the driving mode A may be further expanded to multiple modes in combination with horizontal vibration.

[0054] (A1, constant speed walking / running mode with horizontal vibration effect) Specifically, while the rotation angle of the servo motor 2 alternates between two directions, the rotor of the servo motor 2 drives the treadmill roller 1 to vibrate horizontally in the process of rotating in one direction along the first direction when the change width of the rotation angle in the first direction is greater than the change width of the rotation angle in the second direction. This process can be regarded as achieving the vibration effect by periodically turning in the second direction with a certain width in the process of rotating mainly in the first direction.

[0055] The frequency of the horizontal vibration corresponds to the difference between the range of change in the rotation angle in the first direction and the range of change in the rotation angle in the second direction.

[0056] (A2, reciprocating sweep mode with horizontal vibration effect (combining sweep and vibration)) Specifically, in the bidirectional alternating period of the rotor of the servo motor 2, When the rotor of the servo motor 2 reciprocates in the first and second directions by a second width within a predetermined vibration period in the process of changing the rotation angle by a first width along the first direction, the rotor drives the treadmill roller 1 to oscillate horizontally at a second frequency in the process of sweeping horizontally at the first frequency. This process can be regarded as maintaining the effect of always reciprocating with a small width in the process of moving horizontally in a reciprocating circular motion with a large width.

[0057] The predetermined oscillation period is less than the bidirectional alternating period, the first width is greater than the second width, and the first frequency is less than the second frequency.

[0058] (Drive mode B, unidirectional rotation) Specifically, when the rotation angle changes in one direction, the servo motor 2 drives the treadmill roller 1 to rotate in one direction. This mode includes a walking function and a running function based on low speed and / or variable speed. The drive device of the treadmill according to the present application may drive the treadmill roller to rotate in the forward direction or in the reverse direction.

[0059] In one possible embodiment, the drive device of the treadmill further includes a speed adjusting transmission mechanism. The torque output by the transmission shaft of the servo motor 2 is adjusted by the speed adjusting transmission mechanism and then input to the treadmill roller 1. The speed adjusting transmission mechanism is, for example, a reducer, a pulley and a belt, a sprocket and a chain, etc.

[0060] Specifically, the combined structure of the pulley and belt is relatively simple, and the installation and maintenance are easy. The belt transmission has a buffering and vibration absorbing function, and can further reduce the shock and vibration during the transmission process. In addition, the transmission ratio can be easily changed by adjusting the diameter ratio of the pulleys, and the output torque of the servo motor can be adjusted.

[0061] The driving device of the treadmill of the present application further utilizes the physiological health horizontal rhythm to realize various and rich exercise modes, and improve the user's usage experience and fitness effect. In addition, by providing multiple interactive methods, the driving mode of the device can be controlled to make it easier for the user to use. The horizontal rhythm can promote blood circulation and help prevent cardiovascular diseases.
