Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and in particular to a load-bearing mechanism for fitness equipment and an aerobic fitness device based on Internet technology. Background Technology

[0002] Cycling is a healthy and natural form of aerobic exercise. Long-term cycling can effectively enhance cardiovascular function, improve metabolism and immunity. However, outdoor cycling is greatly affected by external factors, such as outdoor environment, weather, outdoor temperature, and air quality, which cannot provide a stable operating environment for cyclists.

[0003] In response, Chinese invention patent CN114404879B proposes a multi-sensory fitness system based on virtual reality, including a bicycle, VR glasses, a frame, and a platform that can simulate inclines and angles. The bicycle is mounted on the platform via a bracket. A conical groove is opened at the axle of the bicycle's rear wheel, and a friction plug for providing resistance or assistance to the rear wheel to simulate going uphill or downhill is slidably connected inside the conical groove. A stabilizing belt for stabilizing the rear wheel is installed under the bicycle's rear wheel, and a turntable for detecting the steering angle of the front wheel is located under the bicycle's front wheel. A fan for simulating wind direction is installed on the frame. This device combines virtual reality with cycling, allowing users to exercise indoors for extended periods without feeling bored.

[0099] Furthermore, such as Figures 1-3 As shown, the load module includes: a load housing 61, a load shaft 62, several paddles 63, a hydraulic assembly, and a transmission assembly. The load housing 61 is fixedly mounted on the top of the support plate 1, and hydraulic oil is pre-stored in the inner cavity of the load housing 61. The load shaft 62 is arranged radially within the inner cavity of the load housing 61, and both ends of the load shaft 62 are rotatably connected to the inner wall of the load housing 61. Several paddles 63 are mounted on the load shaft 62, and the head end of any paddle 63 is fixedly connected to the load shaft 62. The hydraulic assembly is mounted on the support plate 1, connected to the load housing 61, and electrically connected to the main unit, for transmitting hydraulic oil to the inner cavity of the load housing 61.

[0101] Furthermore, such as Figures 1-3 As shown, the piping system includes: an oil pump (not shown in the figure), an inlet pipe 6441, a second electrically controlled valve 6442, an outlet pipe 6443, a third electrically controlled valve 6444, a second air nozzle 6445, and a fourth electrically controlled valve 6446. The oil pump is fixedly installed at the bottom of the inner cavity of the reservoir and is electrically connected to the main unit. One end of the inlet pipe 6441 is connected to the oil pump, and the other end of the inlet pipe 6441 is connected to the lower part of the inner cavity of the load housing 61 for transmitting hydraulic oil. The second electrically controlled valve 6442 is installed on the inlet pipe 6441 and is electrically connected to the main unit for controlling the opening and closing of the inlet pipe 6441. One end of the outlet pipe 6443 is connected to the load housing 6446. The lower part of the inner cavity is connected, and the other end of the oil outlet pipe 6443 is connected to the inner cavity of the reservoir bladder to transmit hydraulic oil; the third electrically controlled valve 6444 is installed on the oil outlet pipe 6443 and is electrically connected to the main unit to control the opening and closing of the oil outlet pipe 6443; the second air nozzle 6445 is fixedly installed on the top of the load housing 61, and one end of the second air nozzle 6445 penetrates through the outer wall of the load housing 61 and is connected to the upper part of the inner cavity of the load housing 61 to ensure the air pressure balance inside and outside the load housing 61; the fourth electrically controlled valve 6446 is installed on the second air nozzle 6445 and is electrically connected to the main unit to control the opening and closing of the second air nozzle 6445.

[0102] Furthermore, such as Figure 1 , 2As shown in Figures 4 and 6, the transmission assembly includes: an assembly plate 651, a pair of first gears 652, a second gear 653, a first synchronous pulley 654, a second synchronous pulley 655, and a transmission belt 656; the assembly plate 651 is fixedly mounted on the top of the support plate 1; the pair of first gears 652 are rotatably mounted on the assembly plate 651, and each pair of first gears 652 is connected to a pair of roller shafts 3 respectively, with any one first gear 652 rotating coaxially with the corresponding roller shaft 3 to transmit power to the pair of roller shafts 3; the second gear 653 is rotatably mounted on the assembly plate 651, and meshes with the pair of first gears 652 to transmit power to the pair of roller shafts 3. The first gear 652 provides power; the first synchronous pulley 654 is rotatably mounted on the mounting plate 651, and is connected to the second gear 653. The first synchronous pulley 654 and the second gear 653 rotate coaxially to transmit power to the second gear 653; the second synchronous pulley 655 is rotatably mounted on the load housing 61, and is connected to the load shaft 62. The second synchronous pulley 655 and the load shaft 62 rotate coaxially; the transmission belt 656 is sleeved on the first synchronous pulley 654 and the second synchronous pulley 655 to drive the second synchronous pulley 655 and the first synchronous pulley 654 to rotate synchronously.

[0103] When a user uses this device for cycling training, the rear wheel of the bicycle 10 outputs power, driving a pair of rollers 3 to rotate. During the rotation of the rollers 3, a pair of first gears 652 rotate synchronously. During the rotation of the first gears 652, they mesh with a second gear 653, driving the second gear 653 to rotate. The second gear 653 drives a first synchronous pulley 654 to rotate synchronously. The first synchronous pulley 654, through the power transmission of the transmission belt 656, drives a second synchronous pulley 655 to rotate. During the rotation of the second synchronous pulley 655, the load shaft 62 and several paddles 63 rotate within the inner cavity of the load housing 61. The hydraulic components control the resistance experienced by the load shaft 62 and several paddles 63 during rotation by adjusting the amount of hydraulic oil in the inner cavity of the load housing 61.

[0104] The working principle of the hydraulic components is as follows: When it is necessary to increase the forward resistance of the bicycle 10, the main unit controls the third electrically controlled valve 6444 to close and controls the first electrically controlled valve 643, the second electrically controlled valve 6442, and the fourth electrically controlled valve 6446 to open. At the same time, the main unit controls the oil pump to start, so that the oil pump pumps the hydraulic oil stored in the reservoir cavity into the inner cavity of the load housing 61 through the oil inlet pipe 6441, so that the hydraulic oil content in the inner cavity of the load housing 61 continuously increases. As the hydraulic oil level in the inner cavity of the load housing 61 continuously rises, the air in the inner cavity of the load housing 61 is discharged through the second air nozzle 6445, thereby achieving the goal of increasing the hydraulic oil content in the inner cavity of the load housing 61. The purpose of increasing the amount of water is to increase the resistance experienced by several paddles 63 during rotation, thereby increasing the resistance experienced by the bicycle 10 during forward movement. Conversely, the main unit opens the first electronically controlled valve 643, the third electronically controlled valve 6444, and the fourth electronically controlled valve 6446, while keeping the second electronically controlled valve 6442 closed. The hydraulic oil in the inner cavity of the load housing 61 can automatically flow back to the inner cavity of the oil reservoir through the oil outlet pipe 6443, thereby reducing the resistance experienced by several paddles 63 during rotation. In addition, this device can also apply power to a pair of roller shafts 3 through the load module, ensuring the rotation speed of the rear wheel of the bicycle without requiring manual driving by the user, thus simulating the movement of the bicycle 10. The effect on a downhill road: when the load assembly applies power to a pair of rollers 3, the main unit controls the second and third electrically controlled valves 6442 and 6444 to open, and controls the first and fourth electrically controlled valves 643 and 6446 to remain closed. Simultaneously, the main unit controls the oil pump to start, and the oil pump inputs hydraulic oil from the reservoir cavity into the load housing 61 cavity through the oil inlet pipe 6441. As the amount of hydraulic oil in the load housing 61 cavity gradually increases, the air pressure in the load housing 61 cavity also increases. This pressure in the load housing 61 cavity forces the hydraulic oil back into the reservoir cavity, achieving hydraulic oil circulation. During the oil circulation process, the hydraulic oil drives several paddles 63 to rotate the load shaft 62. The load shaft 62 drives the second synchronous pulley 655 to rotate synchronously. The second synchronous pulley 655 transmits power through the transmission belt 656, which in turn drives the first synchronous pulley 654 to rotate synchronously. During the rotation of the first synchronous pulley 654, the first synchronous pulley 654 drives the second gear 653 to rotate. The second gear 653 meshes with a pair of first gears 652, which in turn drives the pair of first gears 652 to rotate, which in turn drives a pair of rollers 3 to rotate actively. During the rotation of the rollers 3, the friction between the rollers 3 and the rear wheel of the bicycle 10 drives the rear wheel of the bicycle to rotate.

[0105] like Figure 1 , 24. Another embodiment of the present invention discloses an aerobic fitness equipment based on Internet technology. The load mechanism of the fitness equipment further includes: VR glasses (not shown in the figure), mounting bracket 7, bearing shell 8, bearing ring 81 and posture adjustment module.

[0106] Specifically, such as Figure 1 , 2 As shown in Figure 4, the VR glasses are worn on the user's head and are electrically connected to the host. The mounting bracket 7 is fixedly mounted on the top of the support plate 1 and is connected to the bicycle 10 for detachably mounting the bicycle 10 onto the support plate 1.

[0110] When a user uses this device for cycling training, the rear wheel of bicycle 10 outputs power, driving a pair of rollers 3 to rotate. A first sensor detects the number of rotations of the rollers 3 in real time and transmits the data to the host computer. The host computer records the total number of rotations of the rollers 3 as the distance traveled by bicycle 10, and records the number of rotations of the rollers 3 per unit time as the speed of bicycle 10. A second sensor detects the deflection angle of turntable 4 in real time and transmits the detection data to the host computer. The deflection time and angle of turntable 4 are recorded as the steering control command output by turntable 4. The host computer transmits the data via V... The R-glasses present the user with images of the road conditions while cycling and match the road conditions with the user's distance and speed. Based on the steering commands output by the second sensor from the turntable 4, the system selects different routes for the user on the current map. During the cycling process, the posture adjustment module controls the tilt angle of the support plate 1 in various directions to simulate the posture of the bicycle 10 when cycling uphill / downhill / turning. The main unit can download maps and obtain motion data from multiple online users via the Internet for comparison, enhancing the fun of the device.

[0111] The working principle of the adjustment module is as follows: During the user's ride, the main unit controls several second motors 984 to drive several corresponding I-beams 983 to rotate, causing the I-beams 983 to wind up the traction rope 985 a certain distance. At the same time, the main unit controls the remaining second motors 984 to drive the corresponding I-beams 983 to rotate in the opposite direction, causing the remaining I-beams 983 to release the traction rope 985 a certain distance. The traction rope 985 pulls the drive end of the connecting bracket, and the connecting bracket 981 drives the bearing plate 1 to rotate towards the user's side at a certain angle, thereby causing the bicycle 10 set on top of the bearing plate 1 to tilt to either side. The bicycle 10 is tilted at a certain angle to achieve the body posture of the bicycle 10 when riding uphill / downhill / turning. During the user's riding, when the user controls the front wheel of the bicycle 10 to drive the turntable 4 to rotate, the second sensor sends a steering signal. The first motor 976 drives the drive gear 975 to rotate at a certain angle. The drive gear 975 drives the drive ring 971 to rotate at a certain angle by meshing with several tooth grooves 972. In turn, the second assembly ring 94, the first assembly ring 91 and the support plate 1 rotate synchronously at a certain angle to simulate the centrifugal force felt by the user when turning during actual riding.
