Abstract
Description
Technical Field
[0001] This utility model relates to the field of training equipment technology, specifically to an omnidirectional movement protection device. Background Technology
[0002] With the advancement of scientific sports training and medical rehabilitation technology, protective devices are playing an increasingly important role in professional sports training and post-operative rehabilitation. Protective devices generally need to provide stable support and flexible movement. Some existing protective devices, such as those assisting skaters in gliding, turning, and jumping, typically have casters at the bottom for multi-directional movement. However, these casters require user-driven power, limiting their use to professional training, rehabilitation training, and post-operative rehabilitation where power is available. Current protective devices fail to meet the needs of automatic movement before rehabilitation training, automatic return after fatigue training, or scenarios where training doesn't require dragging the device but constant protection is necessary—that is, when the user has no power to apply to the device while gliding—making them inconvenient for consumers. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an omnidirectional mobile protection device that allows users to flexibly move the protection device to any position, whether powered or unpowered, thereby enhancing the omnidirectional mobility and flexibility of the protection device and expanding its functionality.

Conversely, when the driving member drives the second wheel body to contact the ground, it can simultaneously drive the first wheel body away from the ground.
[0008] The aforementioned omnidirectional movement protection device further includes a first gear, a second gear, and a third gear in the second wheel set.

[0011] The aforementioned omnidirectional movement protection device includes a protective frame comprising a top component, support rods, and reinforcing rods. Three support rods are distributed circumferentially, and the top end of each support rod is rotatably connected to the top component. A reinforcing rod is connected between each pair of adjacent support rods.
[0012] In the aforementioned omnidirectional movement protection device, the length of the support rod is adjustable, and the opening angle of the support rod is adjustable.

Detailed Implementation
[0023] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 6 This utility model provides an omnidirectional movement protection device, including a protective frame 100, a first wheel set 200, and a second wheel set 300. Multiple sets of both the first wheel set 200 and the second wheel set 300 are distributed at the bottom of the protective frame 100 to improve the stability of the device's movement. The first wheel set 200 includes a non-driven first omnidirectional wheel set 210, allowing for free movement during professional or rehabilitation training. The second wheel set 300 includes a drive member 310 and a second omnidirectional wheel set 320. The drive member 310 drives the second omnidirectional wheel set 320 to rotate, providing additional traction to the protective frame 100 and enabling automatic movement without user power. Through diverse wheel design, users can flexibly move the protection device to any position, whether powered or unpowered, enhancing its omnidirectional mobility and flexibility. It can be used for professional training in skating, ice skating, gymnastics, and other sports, as well as for rehabilitation training of athletes or injured patients, and for automatic movement during the early stages of rehabilitation training, thus expanding the device's functionality.
[0024] Furthermore, in some embodiments, the drive unit 310 can be a structure such as a motor, which can directly drive the second universal wheel set 320 to rotate, thereby causing the protective frame 100 to move automatically. In order to enable the protective frame 100 to stop moving automatically, in some embodiments, a brake structure can be additionally provided at the bottom of the protective frame 100. Of course, in other embodiments, braking can also be achieved by causing the drive unit 310 to drive the second universal wheel set 320 to rotate in the opposite direction.
[0025] Furthermore, in some embodiments, to reduce the sliding resistance of the protective frame 100 when powered by the user, the second wheel assembly 300 can be configured such that the drive member 310 can drive the second omnidirectional wheel assembly 320 to contact the ground and continue to drive the second omnidirectional wheel assembly 320 to rotate; the drive member 310 can also drive the second omnidirectional wheel assembly 320 away from the ground. When the user provides power to make the protective frame 100 slide, the drive member 310 can drive the second omnidirectional wheel assembly 320 away from the ground, thus reducing the sliding resistance of the protective frame 100. When the user does not provide power, the drive member 310 can drive the second omnidirectional wheel assembly 320 to contact the ground and continue to drive the second omnidirectional wheel assembly 320 to rotate, thereby driving the protective frame 100 to slide automatically under the action of friction.
[0026] Furthermore, in some embodiments, the second omnidirectional wheel assembly 320 adopts a bidirectional floating drive structure. The second omnidirectional wheel assembly 320 includes a first wheel body 321 and a second wheel body 322. When the drive member 310 drives the first wheel body 321 to contact the ground, it can simultaneously drive the second wheel body 322 away from the ground. At this time, the rotation of the first wheel body 321 can drive the protective frame 100 to slide in one direction. When the drive member 310 drives the second wheel body 322 to contact the ground, it can simultaneously drive the first wheel body 321 away from the ground. At this time, the rotation of the second wheel body 322 can drive the protective frame 100 to slide in the other direction.
[0027] Furthermore, to achieve the bidirectional floating drive structure of the second omnidirectional wheel assembly 320, in some embodiments, the drive element 310 can be designed in two sets, one set for driving the first wheel 321 / second wheel 322 to contact and separate from the ground, and the other set for driving the rotation of the first wheel 321 / second wheel 322. (Refer to...) Figures 2 to 4In some other embodiments, the second omnidirectional wheel assembly 320 can be configured as follows: the second wheel assembly 300 further includes a first gear 330, a second gear 340, and a third gear 350. A fixed frame 400 is provided at the bottom of the protective frame 100. The driving component 310 is fixedly mounted on the fixed frame 400. The first gear 330 is connected to the driving component 310. The second gear 340 and the third gear 350 are both meshed with the first gear 330 and positioned on opposite sides of the first gear 330. The first wheel body 321 is coaxially connected to the second gear 340, and the second wheel body 322 is coaxially connected to the third gear 350. In the initial state, both the first wheel body 321 and the second wheel body 322 are in a floating state, that is, they do not contact the ground. When the drive member 310 drives the first gear 330 to rotate in the first direction, the second gear 340 and the third gear 350, which are meshed with the first gear 330, rotate in opposite directions. At this time, since both the first wheel body 321 and the second wheel body 322 are in a floating state, the second gear 340 and the third gear 350 can rotate around the gear shaft of the first gear 330, that is, they exhibit the motion state of planetary gears. The second gear 340 moves closer to the ground, while the third gear 350 moves away from the ground, thereby driving the first wheel body 321 to move closer to the ground and contact the ground, while the second wheel body 322 moves away from the ground. When the drive member 310 continues to drive the first gear 330 to rotate, since the first wheel body 321 is restricted by the ground, the second gear 340 can no longer rotate around the gear shaft of the first gear 330. At this time, the second gear 340 will rotate around its own gear shaft, thereby driving the first wheel body 321 to contact the ground and rotate. Under the action of friction, the protective frame 100 is driven to slide. Similarly, when the driving member 310 drives the first gear 330 to rotate in the second direction, the second gear 340 and the first wheel body 321 will move away from the ground, and the third gear 350 and the second wheel body 322 will move closer to the ground. As the driving member 310 continues to drive the first gear 330 to rotate in the second direction, the third gear 350 will rotate around its own gear shaft, thereby causing the second wheel body 322 to contact the ground and rotate. Under the action of friction, this drives the protective frame 100 to slide. Furthermore, the second wheel set 300 also includes a driving gear 360 and a transmission gear 370. The driving gear 360 is connected to the output end of the driving member 310, and the transmission gear 370 meshes with the driving gear 360, and is coaxially connected to the first gear 330. When the driving member 310 starts, it will directly drive the driving gear 360 to rotate, thereby driving the transmission gear 370 meshing with the driving gear 360 to rotate, and finally driving the first gear 330 coaxially connected to the transmission gear 370 to rotate. Furthermore, a counterweight structure can be provided on the first wheel 321 and the second wheel 322 to ensure that after the first wheel 321 / second wheel 322 contacts the ground, it can continue to rotate and slide in contact with the ground without bouncing.
[0028] Furthermore, referring to Figure 1 , Figure 5 and Figure 6 To improve the structural stability of the entire protective device, the protective frame 100 adopts a tripod support frame, which can fully utilize the inherent stability of a triangle to ensure the structural stability of the entire protective device. Furthermore, in some embodiments, the protective frame 100 includes a top component 110, support rods 120, and reinforcing rods 130. Three support rods 120 are distributed circumferentially, and the top end of each support rod 120 is rotatably connected to the top component 110. A reinforcing rod 130 connects each pair of adjacent support rods 120. The structural design of the reinforcing rods 130 further enhances the structural strength and stability of the entire protective device.
[0029] Furthermore, the length of the support rod 120 is adjustable, and the opening angle of the support rod 120 is also adjustable, so as to adjust the height of the protective frame 100, thereby making the protective device suitable for users of different heights and expanding the applicable population. Furthermore, to facilitate the length adjustment of the support rod 120, the structure of the support rod 120 can be configured as follows: the support rod 120 includes an upper support rod 121 and a lower support rod 122. The upper support rod 121 and the lower support rod 122 can be connected in a telescopic or detachable manner to adjust the relative position between the upper support rod 121 and the lower support rod 122, thereby adjusting the overall length of the support rod 120. After adjusting to a suitable length, the upper support rod 121 and the lower support rod 122 can be locked using bolts or other structures.
[0030] When the opening angle of the support rod 120 is adjusted, the connection position of the reinforcing rod 130 on the support rod 120 will also change accordingly. Therefore, in some embodiments, a locking assembly 140 is detachably connected to the support rod 120. The locking assembly 140 includes a first locking block 141, a second locking block 142, and a third locking block 143. The first locking block 141 is detachably connected to the support rod 120. The second locking block 142 and the third locking block 143 are rotatably connected to both sides of the first locking block 141, and the second locking block 142 and the third locking block 143 are respectively connected to the reinforcing rods 130 on both sides. When it is necessary to adjust the opening angle of the support rod 120, the first locking block 141 can be removed from the support rod 120 first. At this time, the reinforcing rod 130 can be removed, releasing the restriction of the reinforcing rod 130 on the support rod 120. After adjusting the opening angle of the support rod 120, the first locking block 141 can be reinstalled on the support rod 120 at the appropriate position.
[0031] Furthermore, a plurality of connection holes 123 are provided on the support rod 120, which are distributed along the length of the support rod 120. The first locking block 141 is detachably and rotatably connected to the support rod 120 via a first locking pin 144. The first locking pin 144 is detachably inserted into a connection hole 123 at a suitable position on the support rod 120. The first locking block 141 is provided with a first slot 1411. After the first locking pin 144 is inserted into the connection hole 123, it can rotate within the connection hole 123, thereby driving the first locking block 141 to rotate relative to the support rod 120, and causing the first slot 1411 to engage with the support rod 120, thereby improving the connection stability between the first locking block 141 and the support rod 120. On one side of the support rod 120, a second locking block 142 is rotatably connected to a first locking block 141 via a second locking pin 145, so that the angle between the first locking block 141 and the second locking block 142 can adapt to the angle between the support rod 120 and the reinforcing rod 130. The second locking block 142 is provided with a second slot 1421, which engages with the end of the reinforcing rod 130 to improve the connection stability between the second locking block 142 and the reinforcing rod 130. Similarly, on the other side of the support rod 120, a third locking block 143 is rotatably connected to the first locking block 141 via a third locking pin 146, and the third locking block 143 is provided with a third slot 1431, which engages with the end of the reinforcing rod 130.
[0032] This protective device can be applied to various scenarios, such as training beginners or professional athletes in skating, ice skating, or gymnastics for gliding, spinning, and jumping, or rehabilitation training for athletes and injured patients. When used for rehabilitation training of ordinary injured patients, the height of the protective frame 100 can be lowered, allowing the user to sit inside the frame and support their hands for forward movement. Alternatively, the protective frame 100 can be raised and fitted with a shoulder strap that attaches to the user, allowing training directly below the frame, such as in gymnastics. The user can also drag the protective frame 100 forward while gliding, such as in ice skating or ice skating training. Furthermore, the drive unit 310 can automatically propel the protective frame 100 forward during gliding, providing protection without interfering with the user's training. When using this protective device, instructors do not need to be constantly present, enhancing the user's self-training and promoting progress. When the protective device is used for skating and ice skating training, a wheel with a blade can be added to the side of the first wheel body 321 / second wheel body 322 to increase weight and friction, so as to prevent bouncing or slipping.
[0033] Furthermore, when applied to skating, ice skating, or gymnastics training, the harness can be equipped with shock absorbers to extend the trainee's time in the air, enabling them to smoothly complete aerial maneuvers and protecting their knees, reducing the risk of injury. The shock absorption effect of the harness can be achieved using structures similar to automatic safety harnesses used by climbers, which tighten the rope during jumps and provide cushioning during descent for a slow descent. Alternatively, it can be achieved using a combination of car seat belts and hydraulic rods. During jumps, the characteristics of a car seat belt allow for rapid tightening of the harness, while the hydraulic rods provide cushioning during descent for a slow descent. To further enhance the equipment's intelligence, three flat beam tensioners in the X, Y, and Z directions can be installed on the protective frame 100. A triaxial force measuring mechanism can detect the force exerted by the human body on the flat beam tensioners. By analyzing the magnitude and duration of the force, the trainee's ability to complete maneuvers at a specific height can be determined, thereby assessing the trainee's airborne height and analyzing whether the trainee can successfully complete the corresponding maneuver at that height. In addition, an image analysis system can be introduced. This system uses cameras to capture images and employs artificial intelligence to identify the trainee's posture and center of gravity, transmitting the data in real time to a computer to analyze whether the trainee's posture meets standards and whether the center of gravity is correct. Based on the analysis results, the system will provide real-time feedback to help trainees adjust their posture, improve the success rate of jumps, and customize targeted training.
