Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to an intelligent hula hoop. Background Art

[0002] The hula hoop, also known as a fitness ring, has quickly become a popular fitness activity for all ages due to its lightness, aesthetic appeal, and minimal space required for exercise. Skilled users can effectively develop and strengthen their lower back, abdomen, buttocks, and leg muscles, effectively improving flexibility and toughness in the waist, hip, and knee joints. Besides being a standard fitness tool, the hula hoop is also commonly used in competitions, acrobatic performances, and as a weight-loss device. Existing hula hoops are annular in shape, which the user places around their waist and rotates the hoop around the waist using the twisting motion. However, these traditional hula hoops often fall off during use, making them difficult to use, especially for beginners. Consequently, a new smart hula hoop has emerged on the market. These hoops are secured to the waist and equipped with a swinging weight that slides along the hoop's circumference. The force of the twisting motion causes the swinging weight to rotate around the hoop, strengthening the waist. For example, the patent application with publication number CN107456702A, entitled "A Smart Hula Hoop," has a structure comprising a fixed structure and a swinging hammer, wherein the swinging hammer is slidably connected to the fixed structure, wherein the fixed structure comprises a hoop body, wherein an adjustment unit for adjusting the size of the hoop body is sleeved on the hoop body, wherein the adjustment unit can adjust the size of the hoop body, thereby adjusting the tightness of the hula hoop around the user's waist, making it easier for the user to use the hoop, wherein the adjustment unit is provided with a pressure plate on the side of the hoop body, wherein the pressure plate presses on the user's abdomen, thereby protecting the user's abdomen. Another example is the patent application with publication number CN210873909U, entitled "A Smart Hula Hoop," wherein the structure comprises a main frame and a movable mechanism, wherein a sub-frame is movably mounted on the right side of the inner wall of the main frame, and a fixing bolt is movably mounted on one side of the outer wall of the sub-frame, wherein the movable mechanism is movably mounted on the inner wall of the main frame, and a movable frame is movably mounted on the right side of the outer wall of the main frame, wherein a positioning bolt is movably connected to the top of the movable frame, and a shock absorbing mechanism is movably mounted on the other side of the outer wall of the main frame.Another example is the smart hula hoops with publication numbers CN214388659U, CN212817804U, and CN212593697U, in which the back of the pressure plate is connected to a screw, and the length of the pressure plate extended by rotating the screw is adjusted to adjust the size of the waist circumference; the above-mentioned smart hula hoops in the prior art have the following shortcomings in use: first, the fixation between the hula hoop and the waist is achieved by reducing the size of the hoop body or setting a spring or other shock-absorbing mechanism inside the hoop body to achieve the fixation between the hula hoop and the waist, which is relatively cumbersome to operate, especially the hula hoop in which the pressure plate is pressed against the abdomen by the elastic force of the spring, although there is an elastic force between the pressure plate and the abdomen, the fixation between the hula hoop and the waist is relatively cumbersome. The invention provides a kind of cushioning, but when the waist is twisted, the up and down swinging amplitude of the ring body is large, which causes the swing hammer to rotate unstablely; secondly, the radial adjustment amplitude of the pressure plate connected by a screw is small, and the user range is narrow; furthermore, the screw connecting the pressure plate is generally arranged along the radial direction of the ring body. In the process of human body twisting waist, the force of twisting waist applies a shear force deviating from the axial direction of the screw on the screw connecting the pressure plate, which causes damage to the thread on the screw or even fracture of the screw; in addition, the expansion and contraction adjustment of the pressure plate requires the simultaneous rotation adjustment of the pressure plate and the screw, which requires first adjusting the extended length of the pressure plate and then wearing it on the abdomen of the human body. The expansion and contraction adjustment operation of the pressure plate is very inconvenient. Summary of the Invention

[0022] After adopting the above structure, the intelligent hula hoop of the present invention has the following advantages compared with the prior art:

[0023] 1. Compared with the structure in the prior art where the pressure plate is connected to the annular ring body by a screw, the intelligent hula hoop pressure plate of the present invention is connected to the annular ring body by a folding bracket, and the folding bracket is composed of a first support rod and a second support rod. The connection structure of the pressure plate is more stable and firm, and has a longer service life. Moreover, a driving member is used to drive the first end of the second support rod to slide in the annular ring body, so that the folding bracket can be unfolded or folded. The folding bracket has a large unfolding range, so that the distance adjustment range of the pressure plate relative to the annular ring body is large, thereby meeting the use of people with different waist circumferences and having a wide range of use. Furthermore, the angle between the first support rod and the second support rod can be adjusted by simply moving the driving member, thereby realizing the position adjustment of the pressure plate, and its operation is simple and convenient.

[0024] 2. The first support rod and the second support rod of the folding bracket are set to be symmetrical about the center line of the pressure plate, and the distance between the first end of the first support rod and the second support rod is greater than the distance between the second end; in this way, the first support rod and the second support rod are set in an "eight" shape, and when the annular ring body is moved by the human body, the force of the human body on the pressure plate is applied to the first support rod and the second support rod, and is evenly dispersed on the annular ring body; the force applied by the human body on the pressure plate is generally in the direction of circumferential rotation of the annular ring body, and due to the angle setting of the first support rod and the second support rod, the force on the pressure plate is applied to the annular ring body along the axial direction of the first support rod or the second support rod, or most of the force on the pressure plate is applied to the annular ring body along the axial direction of the first support rod or the second support rod; in this way, compared with the prior art, in which the twisting force applies a shear force deviating from the axial direction of the screw connecting the pressure plate, the folding bracket formed by the first support rod and the second support rod is less likely to be damaged and has a longer service life.

[0025] 3. The setting of the locking mechanism on the driving member can lock the driving member at any position of its stroke, so that the structure of the pressure plate is more stable and firm after the position is adjusted, and the sliding adjustment of the driving member on the annular ring body has no gear limit, so that the distance adjustment range of the pressure plate relative to the annular ring body is larger, which can meet the needs of different users; moreover, the user can easily adjust the contact between the pressure plate and the abdomen by wearing the annular ring body on the abdomen, without having to remove the annular ring body for adjustment, and the operation is very convenient.

[0026] 4. In the intelligent hula hoop of the present invention, there are two pressure plates and two folding brackets corresponding to the pressure plates, and an arc-shaped slide is provided in the annular ring body. An arc-shaped sliding rod is slidably fitted in the arc-shaped slide, and the arc-shaped sliding rod is respectively connected to the first end of the second support rod in the two folding brackets, so that the arc-shaped sliding rod can drive the two folding brackets to unfold or fold at the same time under the drive of the driving member; the setting of the arc-shaped sliding rod enables the pressure plates to be linked, and when adjusting the position of the pressure plates, only the driving member needs to be operated to adjust the distance of all the pressure plates, and the pressure plate distance adjustment can be completed in one step, and the operation of adjusting the pressure plate distance is very simple and convenient.

[0027] 5. The positioning teeth provided on the annular ring bodies on both sides of the arc-shaped sliding hole cooperate with the pressure block and the knob on the driving member. When the knob is in the tightened state, the locking teeth of the pressure block and the positioning teeth are engaged with each other to lock the position of the driving member. The setting of the positioning teeth and the locking teeth on the pressure block makes the position locking of the driving member more secure.

[0028] 6. The provision of an annular wall on the outer edge of the opening on the inner side wall of the annular ring body protects the connection between the first support rod and the second support rod and the annular ring body, thereby preventing the annular ring body from being damaged or the first support rod and the second support rod from being broken when the first support rod and the second support rod rotate.

Example 1:

[0042] See also Figures 1 to 9 As shown;

[0043] This embodiment discloses a smart hula hoop, which includes an annular hoop body 1. In this embodiment, the annular hoop body 1 includes two arc-shaped first hoop bodies 100 and second hoop bodies 101, and the first end of the first hoop body 100 is hinged to the first end of the second hoop body 101; the second end of the first hoop body 100 is connected to a plug 7, and the second end of the second hoop body 101 is provided with a slot for plugging the plug 7, and the plug 7 at the second end of the first hoop body 100 is plugged into the slot at the second end of the second hoop body 101. In this way, the first circle body 100 can be rotated to open or close relative to the second circle body 101. Specifically, the first end of the first circle body 100 is connected to a pin 111, and the free end of the pin 111 is rotatably connected to the first end of the second circle body 101 through a pin shaft; the plug 7 at the second end of the first circle body 100 includes two symmetrically arranged plug-ins 700, and an elastic member is connected between the two plug-ins 700; the outer side walls of the two plug-ins 700 are connected with outwardly protruding buttons 702, and the first circle body 100 is provided with two button 702 holes, and the buttons 702 of the two plug-ins 700 are respectively clearance-fitted in the two button 702 holes; the free ends of the two plug-ins 700 are respectively connected with outwardly protruding card blocks 701, and the inner side wall of the slot at the second end of the second circle body 101 is provided with a card groove for elastically engaging the card block 701. In this way, the plug 7 at the second end of the first coil body 100 is inserted into the slot at the second end of the second coil body 101 and the block 701 on the two plug-ins 700 is connected to the slot, so that the second end of the first coil body 100 is connected to the second end of the second coil body 101; when the elastic force of the elastic member is overcome, the buttons 702 of the two plug-ins 700 are pressed, and the block 701 can be disengaged from the slot, thereby disengaging the plug 7 from the slot, and the second ends of the first coil body 100 and the second coil body 101 can be relatively open, which makes it convenient for the user to wear the hula hoop on the abdomen or remove it from the abdomen. In other embodiments, the annular coil body 1 can be an entire coil body, or it can be an annular coil body 1 composed of three, four, or other multiple coil bodies connected at the end.

[0044] In this embodiment, the outer wall of the annular ring body 1 is provided with an annular groove 102 arranged along its circumference; a slider 103 is provided in the gap within the annular groove 102. The slider 103 can rotate along the annular groove 102 without being disengaged from the annular groove 102. In this embodiment, in order to make the slider 103 rotate more smoothly, without noise or with low noise, a plurality of pulleys are provided on the slider 103, which are slidably or rollingly connected to the inner wall of the annular groove 102. The outer side of the annular ring body 1 of the smart hula hoop is provided with a swing hammer 2 connected to the slider 103. When the human body twists, the annular ring body 1 can be driven to move, thereby causing the swing hammer 2 and the slider 103 to rotate around the circumference of the annular groove 102, thus achieving the purpose of waist exercise.

[0045] The inner side of the annular ring body 1 of the smart hula hoop is provided with at least one pressure plate that is against the human abdomen; the number of the pressure plates can be one, two, three or four, etc., and the specific number can be set according to needs. In the present embodiment, the number of the pressure plate is one, and the outer wall of the pressure plate close to the human abdomen is set to an arc that matches the curvature of the abdomen, and a plurality of massage protrusions are distributed on the arc-shaped outer wall of the pressure plate. A folding bracket is provided between the pressure plate and the annular ring body 1, and the folding bracket can be unfolded or folded. In the present embodiment, the folding bracket includes a first support rod 401 and a second support rod 402, and the first support rod 401 and the second support rod 402 are both arc-shaped, and the first support rod 401 and the second support rod 402 are symmetrically arranged about the center line of the pressure plate; the distance between the first ends of the first support rod 401 and the second support rod 402 is greater than the distance between the second ends. The first end of the first support rod 401 is hinged to the annular ring body 1, the second end of the first support rod 401 is hinged to the pressure plate, the first end of the second support rod 402 can be slidably fitted in the annular ring body 1 along the circumference of the annular ring body 1, and the second end of the second support rod 402 is hinged to the pressure plate; a driving member is connected to the annular ring body 1 of the smart hula hoop, and the driving member is connected to the first end of the second support rod 402, and is used to drive the first end of the second support rod 402 to slide in the annular ring body 1, so that the folding bracket can be unfolded or folded to adjust the distance of the pressure plate relative to the annular ring body 1. Compared with the structure in the prior art in which the pressure plate is connected to the annular ring body 1 by a screw, the pressure plate of the smart hula hoop of the present invention is connected to the annular ring body 1 by a folding bracket, and the folding bracket is composed of a first support rod 401 and a second support rod 402, so that the connection structure of the pressure plate is more stable and firm, and the service life is longer; and a driving member is used to drive the first end of the second support rod 402 to slide in the annular ring body 1, so that the folding bracket is unfolded or folded. The unfolding range of the folding bracket is large, and the distance adjustment range of the pressure plate relative to the annular ring body 1 is large, so that it can meet the use of people with different waist circumferences and has a wide range of use; furthermore, the angle between the first support rod 401 and the second support rod 402 can be adjusted by simply actuating the driving member, so as to realize the position adjustment of the pressure plate, and the operation is simple and convenient. The first support rod 401 and the second support rod 402 of the folding bracket are arranged in an "eight" shape. When the annular ring body 1 is moved by the human body, the force of the human body on the pressure plate is applied to the first support rod 401 and the second support rod 402 and is evenly dispersed on the annular ring body 1; the force applied by the human body on the pressure plate is generally in the direction of the circumferential rotation of the annular ring body 1. Due to the angular setting of the first support rod 401 and the second support rod 402, the force on the pressure plate is applied along the axial direction of the first support rod 401 or the second support rod 402, or most of the force on the pressure plate is applied to the annular ring body 1 along the axial direction of the first support rod 401 or the second support rod 402; compared with the prior art, in which the twisting force applies a shear force deviating from the axial direction of the screw connecting the pressure plate, the folding bracket formed by the first support rod 401 and the second support rod 402 is less likely to be damaged and has a longer service life.

[0046] In this embodiment, the driving member is slidably engaged with the annular ring body 1 along the circumference of the annular ring body 1, and a locking mechanism is provided on the driving member. The locking mechanism is used to place the driving member in a locked state or a released state. In the locked state, the driving member is fixed in position relative to the annular ring body 1, and the distance of the pressure plate relative to the annular ring body 1 is fixed. In the released state, the driving member slides along the circumference of the annular ring body 1, and the distance of the pressure plate relative to the annular ring body 1 is adjustable. Specifically, the annular ring body 1 is provided with an arcuate sliding hole 104 extending along the length direction of the annular ring body 1, and the driving member is slidably engaged within the arcuate sliding hole 104; a knob 5 is threadedly connected to the driving member, and the knob 5 is disposed on the outside of the annular ring body 1; when the knob 5 is tightened, the driving member is locked to the annular ring body 1, and when it is loosened, the driving member can slide and adjust its position on the annular ring body 1. In this embodiment, the driving member is directly connected to the first end of the second support rod 402, and the driving member is slidably arranged on the annular ring body 1, and the sliding of the driving member drives the first end of the second support rod 402 to slide; in other embodiments, the driving member can also be rotatably connected to the annular ring body 1, and a pull rope is wound on the driving member, and the free end of the pull rope is connected to the first end of the second support rod 402, and a torsion spring is connected between the first support rod 401 and the second support rod 402, and the force applied by the torsion spring to the second support rod 402 is opposite in direction to the force applied by the pull rope to the second support rod 402; when the driving member is rotated, the driving member winds up the pull rope, thereby driving the first end of the second support rod 402 to slide in the annular ring body 1; when the driving member releases the pull rope, the first end of the second support rod 402 drives the first end of the second support rod 402 to slide in the opposite direction along the annular ring body 1 under the elastic force of the torsion spring; the locking mechanism is used to limit the rotation of the driving member, and can be achieved by a pin, a locking screw, a ratchet, etc.

[0047] See again Figure 4As shown, in this embodiment, a slideway 108 extending circumferentially along the annular ring body 1 is provided within the annular ring body 1, and the first end of the second support rod 402 is slidably engaged within the slideway 108. The provision of the slideway 108 further defines the motion trajectory of the first end of the second support rod 402, making the unfolding and folding of the folding bracket smoother. To enable the driving member to better drive the movement of the first end of the second support rod 402, a curved slide rod 6 is slidably connected within the slideway 108. One end of the curved slide rod 6 is connected to the first end of the second support rod 402, and the other end of the curved slide rod 6 is connected to the driving member. In order to make the curved slide bar 6 slide smoothly in the slide 108, a plurality of convex walls 112 distributed along the length direction of the slide 108 and extending radially along the slide 108 are provided on the inner wall of the slide 108, and the convex wall 112 is provided with an arc-shaped notch 113, and the inner wall of the arc-shaped notch 113 is protruded and set in the slide 108, and the outer wall of the curved slide bar 6 slides with the inner wall of the arc-shaped notch 113; this reduces the contact area between the curved slide bar 6 and the slide 108, thereby reducing the movement resistance of the curved slide bar 6, and the movement of the curved slide bar 6 in the slide 108 is smoother, the noise during sliding friction is small, and the user experience is good.

[0048] See also Figures 6 to 8 As shown, in this embodiment, the locking mechanism utilizes a plurality of positioning teeth 105 distributed along the length of the arcuate sliding hole 104 on the annular ring body 1 on both sides of the arcuate sliding hole 104. A pressure block 500 is slidably mounted on the driver below the knob 5, and a locking tooth 501 is provided at the bottom of the pressure block 500 to engage with the positioning teeth 105. In this embodiment, the pressure block 500 is mounted on the driver through a gap in its center hole 502. When the knob 5 is tightened, the locking teeth 501 of the pressure block 500 engage with the positioning teeth 105 to lock the driver in place. The positioning teeth 105 and the locking teeth 501 on the pressure block 500 further secure the driver's position.

[0049] In this embodiment, the annular ring body 1 is provided with a display screen 8 and a counting module is provided inside the annular ring body 1. The counting module is used to display the number of rotations of the slider 103 on the display screen 8. The arrangement of the display screen 8 and the counting module on the base allows the user to conveniently calculate the number of rotations of the swinging hammer 2 and the energy consumed during the movement, thus being convenient for the user.

See also Figures 6 to 8As shown, the annular ring body 1 on either side of the arcuate sliding hole 104 is provided with a plurality of positioning teeth 105 distributed along the length of the arcuate sliding hole 104. A pressing block 500 is slidably mounted on the driving member below the knob 5, and the bottom of the pressing block 500 is provided with locking teeth 501 that engage with the positioning teeth 105. When the knob 5 is tightened, the locking teeth 501 of the pressing block 500 engage with the positioning teeth 105 to lock the position of the driving member. The arrangement of the positioning teeth 105 and the locking teeth 501 on the pressing block 500 further secures the position of the driving member.

[0052] Other technical solutions of this embodiment are the same as those of the above-mentioned embodiment 1, and will not be described repeatedly in this embodiment. Example 3:

[0053] The smart hula hoop has three pressure plates on its annular ring body 1, and three folding brackets to match the pressure plates. The arc-shaped slide bar 6 is connected to the first ends of the second support rods 402 of the three folding brackets. Thus, when the driving member drives the arc-shaped slide bar 6, the three folding brackets can be simultaneously adjusted to expand or fold. In other embodiments, the number of pressure plates and folding brackets can also be four, five, or more.
