Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, and in particular discloses a treadmill driven by an external brushless motor. Background Art

[0002] With the development of economy and the improvement of living standards, people begin to pay more and more attention to their own health exercise, which makes fitness equipment in the market increasingly popular, such as treadmills. However, because running is tiring, many people cannot stick to regular running, especially those who are not suitable for strenuous exercise. Treadmills do not provide them with a good exercise opportunity. In response to this problem, walking machines that allow people to walk have gradually appeared on the market. Compared with treadmills, walking machines have no special requirements for people and users can use them more easily. Therefore, they are attracting more and more attention and purchases from consumers.

[0003] Many walking machines on the market have evolved from treadmills, and most of them retain the original size of the treadmill. They are relatively large and generally need to be placed in a wider open space for use. Their principles generally follow the treadmill principle, including a walking belt and front and rear rollers. The walking belt is tensioned between the front and rear rollers, and the front roller is driven by a motor to rotate, thereby driving the walking belt to run. Therefore, most of them are equipped with larger motors, which are costly, heavy, and occupy a large space, resulting in the entire walking machine. The size, weight and cost will be relatively high. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, an object of the present invention is to provide a treadmill driven by an outward-rotating brushless motor.

[0005] To achieve the above-mentioned purpose, the present invention discloses an outward-rotating brushless motor-driven treadmill, comprising a frame and a walking belt movably arranged on the frame; further comprising a driving member for driving the walking belt to rotate and a reduction module used in conjunction with the driving member; the reduction module comprises a first wheel body rotatably arranged relative to the frame and a second wheel body arranged at an output end of the driving member, the diameter of the second wheel body being smaller than the diameter of the first wheel body, the second wheel body drives the walking belt to rotate via the first wheel body, a bearing is arranged at one end of the first wheel body, and the first wheel body is rotatably arranged with the frame via the bearing.

[0006] Preferably, an extension portion protrudes from the first wheel body, and the extension portion is cylindrical. The inner ring of the bearing is arranged at one end of the extension portion away from the first wheel body. A cover body is also arranged on the outer ring of the bearing, and the cover body is fixedly arranged relative to the frame. By designing an extension portion protruding from the first wheel body, and the extension portion is a cylindrical structure, a stable installation foundation is provided for the bearing, which not only enhances the stability of the bearing installation, but also effectively disperses the stress and vibration generated by the bearing / first wheel body during operation, thereby improving the overall stability and reliability of the reduction module. A cover body is arranged on the outer ring of the bearing, and the cover body is fixedly arranged relative to the frame. The existence of the cover body effectively prevents external contaminants such as dust and impurities from entering the interior of the bearing, thereby extending the service life of the bearing. In addition, the cover body also plays a certain safety protection role, reducing the potential damage to the bearing caused by accidental touch or impact.

[0007] Preferably, the reduction module also includes a first rod body accommodated inside the first wheel body and the extension part, the first rod body is fixedly arranged relative to the frame, the first wheel body and the extension part are both rotatably arranged with the first rod body, and the cover body is arranged on the first rod body. By arranging the first rod body inside the first wheel body and the extension part, and making the first wheel body and the extension part both rotatably arranged with the first rod body, this design provides a stable support axis for the first wheel body and the extension part. In this way, when the first wheel body is subjected to the transmission torque, it can rotate around the first rod body more stably, reducing the transmission instability and wear problems caused by shaking or offset, thereby enhancing the structural stability of the entire reduction module. The first rod body serves as a fixed support point for the first wheel body and the extension part, simplifying their installation process. At the same time, since the cover body is also arranged on the first rod body, the structure of the entire reduction module is more compact and orderly, and it is also convenient for subsequent maintenance and replacement work. When it is necessary to clean the heat dissipation channel, replace the bearing or adjust the transmission ratio, the relevant components can be located and operated more quickly.

[0008] Preferably, a transmission belt is sleeved on the first wheel body, and one end of the transmission belt away from the first wheel body is arranged on the first wheel body. At least two transmission belts are arranged. The design of multiple transmission belts can increase the safety of the treadmill. When one of the transmission belts breaks due to failure or wear, it will not cause excessive impact on the other belt. The other transmission belts can still maintain traction on the walking belt to prevent the walking belt from suddenly stopping or losing control, reducing the risk of user injury and being more conducive to heat dissipation. When multiple transmission belts are moving, the gaps between them and the relative movement with the surrounding air help to increase air flow. This flowing air can take away part of the heat, thereby reducing the overall temperature of the transmission system.

[0009] Preferably, the frame includes a first frame, a second frame, and a first plate disposed on the first frame and the second frame. The first frame, the second frame, and the first plate are detachably connected. The first plate is used to provide support for the side of the walking belt that is used. Since the first plate is detachably connected to the first frame and the second frame, it is more convenient to operate when the first plate needs to be maintained or replaced, without disassembling the entire frame or affecting other components, thereby reducing maintenance costs and time. The detachable connection design allows the user to adjust the position, quantity, or type of the first plate according to actual needs. For example, when it is necessary to increase the width of the walking belt or adjust its supporting structure, the first plate can be easily replaced or added, thereby improving the flexibility and adaptability of the device. The first plate is the direct supporting surface of the walking belt, and its material and structure have a certain influence on the heat dissipation performance. The detachable connection design allows for convenient selection of materials or structures with better heat dissipation performance to make the first plate, thereby optimizing the heat dissipation performance of the entire device and extending its service life.

[0010] Preferably, the frame further comprises a first roller and a second roller rotatably arranged on the first frame and / or the second frame, the first roller and the second roller are respectively located at both ends of the walking belt to drive the walking belt to rotate, and the first roller and the second roller serve as driving components of the walking belt, and their rotation can smoothly drive the walking belt to perform a circular motion. This design ensures the stability and continuity of the walking belt during the movement process, and provides a good user experience for the user.

[0011] Preferably, a third wheel body is arranged on the second roller body, the axis of the third wheel body is parallel to the axis of the extension part, the third wheel body is used in conjunction with the extension part via a transmission belt, the diameter of the third wheel body is larger than the diameter of the extension part, and the third wheel body and the extension part are connected via a transmission belt. This transmission mode has the advantages of stable transmission, low noise, high transmission efficiency, etc. At the same time, due to the larger diameter of the third wheel body, the transmission belt can be more stable when transmitting power, reduce slippage and wear, and further improve transmission efficiency.

[0012] Preferably, a fourth frame is provided on the side of the first plate body away from the walking belt, and the fourth frame is in an inverted U-shape. Both ends of the fourth frame protrude out of the walking belt to contact the external base surface to stably support the first frame / second frame. The fourth frame serves as a supporting structure, and its inverted U-shape design enables its two ends to firmly contact and be supported on the external base surface. This design effectively disperses the weight of the first frame and the second frame, enhances the stability of the entire frame, and prevents safety hazards caused by shaking or tilting of the equipment during operation.

[0013] Preferably, a third frame is provided on the first frame / second frame, and the third frame is in a U-shaped structure. The third frame is used to install the driving member and the reduction module. A closed groove is provided on the side of the third frame facing the outside world, and a through groove is provided on the side of the third frame away from the outside world. The U-shaped structure of the third frame enables it to fit tightly on the first frame / second frame, providing a stable and compact installation space for the driving member and the reduction module. This design not only reduces the occupied space of the overall structure, but also improves the integration level of the equipment, making the connection between the various components tighter and more stable. The design of the through groove also facilitates the maintenance and inspection of the equipment. When the driving member or the reduction module needs to be inspected, repaired or replaced, the technician can directly access / disassemble the internal components through the through groove without disassembling the entire third frame or other components, thereby saving time and labor costs.

[0014] Preferably, a third roller is also provided on the first frame / the second frame, and the third roller is arranged to rotate and slide relative to the first frame / the second frame, and the third roller is not colinear with the first roller and the second roller. The introduction of the third roller provides an additional support point for the equipment, making the overall structure more stable. At the same time, due to its characteristics of both rotating and sliding, and its layout that is not colinear with the first roller and the second roller, the tension distribution and transmission path of the walking belt can be optimized by adjusting the position, angle and sliding characteristics of the third roller, making the transmission more stable and efficient.

[0015] The beneficial effects of the present invention are as follows: by adopting the design of a deceleration module, in which the diameter of the second wheel body is smaller than the diameter of the first wheel body, effective deceleration of power and increase of torque are achieved. This deceleration and torque increase effect enables the driving part to output greater power at a lower rotational speed, thereby driving the walking belt to rotate smoothly and efficiently. At the same time, a bearing is arranged at one end of the first wheel body. Through the rotation arrangement of the bearing and the frame, not only the friction resistance of the first wheel body during rotation is reduced and the rotation efficiency is improved, but also the service life of the first wheel body and the entire deceleration module is extended. By moving the motor placed in the front of a traditional walking machine or treadmill to the side, and through a multi-stage transmission method, the treadmill roller body and the walking belt are driven to rotate to meet the requirements of use, not only the area where the original motor is fixed on the machine can be saved, but also the machine can be thinned, that is, cost can be saved and part of the space can be saved.

[0031] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0032] See also Figures 1 to 13As shown, an outward-rotating brushless motor-driven treadmill of the present invention comprises a frame 1 and a walking belt 4 movably arranged on the frame 1; it also comprises a driving member 2 for driving the walking belt 4 to rotate, and a deceleration module 3 used in conjunction with the driving member 2; the deceleration module 3 comprises a first wheel body 33 rotatably arranged relative to the frame 1 and a second wheel body 32 arranged at the output end of the driving member 2, the diameter of the second wheel body 32 is smaller than the diameter of the first wheel body 33, the second wheel body 32 drives the walking belt 4 to rotate via the first wheel body 33, a bearing 36 is arranged at one end of the first wheel body 33, and the first wheel body 33 is rotatably arranged with the frame 1 via the bearing 36.

[0033] Specifically, by adopting the design of the deceleration module 3, in which the diameter of the second wheel body 32 is smaller than the diameter of the first wheel body 33, effective power deceleration and torque increase are achieved. This deceleration and torque increase effect enables the driving member 2 to output greater power at a lower rotation speed, thereby driving the walking belt 4 to rotate smoothly and efficiently. At the same time, a bearing 36 is provided at one end of the first wheel body 33. Through the rotation setting of the bearing 36 and the frame 1, not only the friction resistance of the first wheel body 33 during the rotation process is reduced and the rotation efficiency is improved, but also the service life of the first wheel body 33 and the entire deceleration module 3 is extended. By moving the motor placed in the front of the traditional walking machine or treadmill to the side, and through a multi-stage transmission method, driving the treadmill roller body and the walking belt to rotate, the requirements of use can be met. Not only the area where the original motor is fixed on the machine can be saved, but also the machine can be thinned, that is, cost can be saved and part of the space can be saved.

[0034] Specifically, an extension portion 35 protrudes from the first wheel body 33, and the extension portion 35 is cylindrical. The inner ring of the bearing 36 is arranged at the end of the extension portion 35 away from the first wheel body 33. A cover body 37 is also arranged on the outer ring of the bearing 36, and the cover body 37 is fixedly arranged relative to the frame 1. The extension portion 35 protrudes from the first wheel body 33, and the extension portion 35 is a cylindrical structure, which provides a stable installation foundation for the bearing 36, not only enhances the stability of the installation of the bearing 36, but also effectively disperses the stress and vibration generated by the bearing 36 / the first wheel body 33 during operation, thereby improving the overall stability and reliability of the reduction module. A cover body 37 is arranged on the outer ring of the bearing 36, and the cover body 37 is fixedly arranged relative to the frame 1. The existence of the cover body 37 effectively prevents external contaminants such as dust and impurities from entering the interior of the bearing, thereby extending the service life of the bearing. In addition, the cover body 37 also plays a certain safety protection role, reducing the potential damage to the bearing caused by accidental touch or impact.

[0035] Specifically, the cover body 37 is made of a material that is easy to conduct heat and dissipate heat, and the heat dissipation material includes copper, aluminum, silver, graphite, diamond, carbon fiber composite materials, nanomaterials, etc.

[0036] Specifically, in this embodiment, a through hole is provided at the axis of the wheel body, and a plurality of through holes are provided. The plurality of through holes are arranged in a ring array around the axis of the wheel body to increase the heat dissipation area.

[0037] Specifically, the driving member 2 is an external rotating motor, and a fan for heat dissipation is also provided on the driving member 2. The driving member 2 includes a stator part and a rotor part. The fan is arranged on the rotor part for cooling the transmission belt 34. The fan is directly arranged on the rotor part of the driving member 2 (external rotating motor), and the rotational power of the rotor part is used to drive the fan to rotate, thereby realizing active heat dissipation of the transmission belt 34 and its surrounding environment. This design can more effectively take away the heat generated by the transmission belt 34 during high-speed operation, reduce the operating temperature of the transmission belt and the reduction module, and improve the stability and reliability of the entire transmission system. Through effective heat dissipation measures, the problems of thermal expansion and thermal stress concentration caused by high temperature in the transmission belt 34, the reduction module and the internal components of the driving member 2 can be reduced, the aging rate and wear degree of the material can be reduced, thereby extending the service life of these components. The transmission belt 34 runs more smoothly at low temperature, reducing the friction resistance and energy loss caused by high temperature, and improving the transmission efficiency. At the same time, the low temperature environment also helps to maintain the stability of the electromagnetic properties inside the motor, reduce the motor performance fluctuations caused by temperature changes, and improve the operating performance of the whole machine.

[0038] Specifically, in this embodiment, the driving member 2 is a single-sided outward rotating motor. Since the torque of the outward rotation is larger than that of the inward rotation, it can be made shorter and hidden in the side of the frame 1, which can save the need for a special location for installing the motor in the front. This saves transportation costs and packaging space, and through multi-stage transmission, the motor can be miniaturized, which saves both cost and energy.

[0039] Specifically, the deceleration module 3 further includes a first rod 38 accommodated in the first wheel 33 and the extension 35, the first rod 38 is fixedly arranged relative to the frame 1, the first wheel 33 and the extension 35 are both rotatably arranged with the first rod 38, the first rod 38 is arranged on the frame 1, and the cover 37 is arranged on the first rod 38. By arranging the first rod 38 in the first wheel 33 and the extension 35, and making the first wheel 33 and the extension 35 rotatably arranged with the first rod 38, this design provides a stable support axis for the first wheel 33 and the extension 35, so that when the first wheel 33 When subjected to the transmission torque, it can rotate more stably around the first rod body 38, reducing the transmission instability and wear problems caused by shaking or offset, thereby enhancing the structural stability of the entire reduction module. The first rod body 38 serves as a fixed support point for the first wheel body 33 and the extension part 35, which simplifies their installation process. At the same time, since the cover body 37 is also arranged on the first rod body 38, the structure of the entire reduction module is more compact and orderly, and it is also convenient for subsequent maintenance and replacement work. When it is necessary to clean the heat dissipation channel, replace the bearing or adjust the transmission ratio, the relevant components can be located and operated more quickly.

The other transmission belts can still maintain traction on the walking belt 4 to prevent the walking belt from suddenly stopping or losing control, reducing the risk of user injury and being more conducive to heat dissipation. When multiple transmission belts are moving, the gaps between them and the relative movement with the surrounding air help to increase air flow. This flowing air can take away part of the heat, thereby reducing the overall temperature of the transmission system.

The first frame 11, the second frame 12 and the first plate 14 are detachably connected. The first plate 14 is used to provide support for the side of the walking belt 4 that is used. Since the first plate 14 is detachably connected to the first frame 11 and the second frame 12, it is more convenient to operate when the first plate 14 needs to be maintained or replaced, without disassembling the entire frame or affecting other components, thereby reducing maintenance costs and time.
