Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, specifically to assisted fitness training devices. Background Technology

[0002] Ab wheel fitness machines are small, push-type exercise devices that can work muscles and joints and help with weight loss. They are generally made of high-quality engineering plastics, with a simple and attractive design, are sturdy and durable, and easy to use. They are used to exercise various parts of the body, such as the abdomen, waist, hips, and arms, to reduce excess fat. Because they require little space, they are convenient for home use.

[0003] Most ab wheel fitness machines currently available are operated with two hands, with very few that can be operated with one hand. Moreover, they are very difficult to operate, and it is easy to lose control of the speed and get injured. When pulling back, the machine does not have an active assist structure, making it difficult to control the training difficulty independently. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as high operational difficulty, lack of active assistance structure during pull-back exercise, and difficulty in controlling training difficulty independently, this utility model provides an assisted fitness training device.

[0005] The technical solution for this utility model is as follows:

[0006] This utility model provides an assisted fitness training device, including a main body with rollers mounted on it. The rollers' axles are rotatably connected to the main body, and a portion of the rollers extends from the bottom of the main body. A brake wheel is also rotatably mounted on the roller's axle, and the brake wheel is connected to the roller's axle via a one-way transmission structure. The main body also features a manually controlled braking mechanism that works in conjunction with the brake wheel. A reverse assist mechanism is also provided within the main body, which is linked to the braking mechanism. When the braking mechanism is activated, the reverse assist mechanism is simultaneously activated, applying a backward-rotating torque to the rollers.

[0007] Furthermore, the brake structure includes a rotating block having a hinged end that is rotatably connected to the body, a brake pad mounting surface facing the brake wheel, a brake pad being fixedly mounted on the brake pad mounting surface, and a drive end having a portion of the drive end extending to the front side of the body.

[0008] Furthermore, the reverse assist structure includes a motor, a power supply, and a motor start button. The motor is connected to the shaft of the roller, and both the power supply and the motor start button are connected to the motor. When the braking structure is working, it simultaneously drives the motor start button.

[0009] Furthermore, the motor start button is connected to the rotating block.

[0010] Furthermore, the main body includes a base and a housing, with the housing fixedly mounted on the upper side of the base, and the roller shaft rotatably connected to the base.

[0011] Furthermore, a wear-resistant pad is fixedly installed at the bottom of the base on the side of the roller.

[0012] Furthermore, the unidirectional transmission structure uses a unidirectional bearing.

[0013] Furthermore, the unidirectional transmission structure is a ratchet and ratchet assembly.

[0014] Furthermore, the rear side of the main body is connected to a traction plate, and the main body and the plate are detachably connected. A sliding component is installed at the bottom of the plate.

[0015] Furthermore, the upper surface of the pallet has a concave arc-shaped surface.

[0016] The beneficial effects achieved by this utility model are as follows:

[0017] When using this device for fitness training, the user places the trainer in front of them, leans forward, and grasps the main body with one hand. Using their muscles, they control their body's posture and slowly push the trainer forward. This is the first stage of training. After the trainer rolls forward a certain distance, the braking mechanism increases the resistance of the brake wheel. This resistance helps the user control the trainer's forward speed and makes it easier to stop the trainer from moving forward. When the braking mechanism is working, the reverse assist mechanism is activated and applies a backward torque to the roller, which acts as an auxiliary brake. At the same time, this torque also helps the user pull the trainer backward, making the process of pulling the trainer backward less strenuous and thus assisting in the training.

[0027] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] like Figures 1-9 As shown, this utility model provides an assisted fitness training device, including a main body 1. The main body 1 includes a base 101 and a housing 102. The housing 102 is fixedly installed on the upper side of the base 101. A roller 2 is installed on the base 101. The roller's shaft is rotatably connected to the base, preferably through a bearing. A part of the roller extends from the bottom of the base. A brake wheel 3 is also rotatably mounted on the roller's shaft. The brake wheel 3 is connected to the roller 2's shaft through a one-way transmission structure. The housing 102 has a front end and a rear end. The main body is also equipped with a manually controlled braking structure that cooperates with the brake wheel. Controlling the braking structure can increase the resistance of the brake wheel's rotation relative to the main body. After the brake wheel is completely stopped by the braking structure, the roller can no longer rotate towards the front end, thus achieving braking of the roller. At this time, the roller can rotate towards the rear end of the housing 102. Through this principle, after the brake wheel is completely stopped by the braking structure, this training device cannot continue to roll forward on the ground, but can roll backward.

[0029] like Figure 9 As shown, when a user holds this device for fitness training, they place the trainer in front of them, bend over, and grasp the main body 1 with one hand. Using their muscles, they control their body shape and slowly push the trainer forward, thus beginning the first stage of training. After the trainer rolls forward a certain distance, the braking structure increases the resistance of the brake wheel. Due to the one-way transmission structure, the resistance is transmitted to the roller, increasing the resistance to continue pushing the trainer forward. This resistance helps the user control the trainer's speed and better stop it from moving forward. After the brake wheel is completely stopped by the braking structure, the user can keep the trainer on the ground and prevent it from moving forward even if they relax their body. The user then continues to exert force and pulls the trainer backward to begin the second stage of training. In the second stage, the trainer can roll backward smoothly without being affected by the braking structure. By controlling the resistance of the brake, the user can control the difficulty of the training independently.

[0030] like Figure 6As shown, a wear-resistant pad 4 is fixedly installed on the side of the roller at the bottom of the base 101. During use, even if the side of the base rubs against the ground, it can be protected by the wear-resistant pad, thus improving its service life. The wear-resistant pad is preferably made of a material with a smooth surface. When the wear-resistant pad comes into contact with the ground during use, it will not instantly increase the movement resistance of the trainer, allowing the user to better control the movement speed of the trainer.

[0031] like Figure 3 As shown, in the first embodiment of the one-way transmission structure, the shafts of the brake wheel and the roller are connected by a one-way bearing 5.

[0032] like Figure 4 As shown in the second embodiment of the unidirectional transmission structure, the shafts of the brake wheel and the roller are connected by a ratchet assembly 6.

[0033] like Figure 3 As shown, the brake structure includes a rotating block 7, which has a hinged end 701 rotatably connected to the main body. A torsion spring is installed at the connection between the hinged end 701 and the main body. The rotating block has a brake pad mounting surface facing the brake wheel, on which a brake pad 8 is fixedly mounted. The rotating block also has a drive end 702. When no external force is applied to the drive end, the torque of the torsion spring prevents the brake pad from contacting the brake wheel. A portion of the drive end extends to the front side of the housing, and a window is provided in the housing corresponding to the drive end position. When the user holds the housing, they can press the drive end with their fingers to drive the rotating block to rotate around the hinged end, thereby causing the brake pad to squeeze the brake wheel for braking.

[0034] like Figure 7 As shown, a reverse assist structure is also provided within the main body. This reverse assist structure is linked to the braking structure. When the braking structure is working, the reverse assist structure is activated and applies a backward rotational torque to the roller. One specific implementation of the reverse assist structure includes a motor 9 connected to the roller's shaft. The motor is preferably a small hub motor 9, mounted at one end of the roller's shaft and fixedly connected to the main body. The roller's shaft is connected to the rotating part of the hub motor. A power supply 10 and a motor start button 11 are also provided within the main body. Both the power supply 10 and the motor start button 11 are connected to the hub motor. The motor start button is connected to a rotating block 7. Preferably, the motor start button is located on the rear side of the rotating block 7. During braking, the rotating block rotates around the hinge end, driving the motor start button. The motor start button controls the hub motor to operate, applying a backward rotational torque to the roller, thus assisting braking. Simultaneously, this torque also assists the user in pulling the trainer backward, making the backward pulling process easier and thus aiding training.

[0035] like Figure 8As shown, the rear side of the main body is connected to the support plate 12, and the main body and the support plate are detachably connected. The upper surface of the support plate has a concave arc surface, and the bottom of the support plate is equipped with a sliding component 13. The sliding component can be a sliding wheel or a ball bearing. If a sliding wheel is selected, a universal sliding wheel is preferred. When the user is training, the support plate can support the arm, reducing the difficulty of training. The support plate can be removed at any time according to the training situation.

[0036] The above-described embodiments of this utility model do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
