Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a fitness device that mimics hula hoop movement. Background Technology

[0002] Hula hooping, a popular training method, is remarkably effective in activating core muscles, enhancing trunk stability, and boosting fat-burning efficiency. Multiple studies have shown that continuous hula hoop rotation effectively works the rectus abdominis, obliques, and lower back muscles, making it particularly suitable for targeted strengthening exercises for those who lack regular exercise. Due to its rhythmic nature, hula hooping also offers a degree of fun and stress relief, resulting in stable demand in the fitness market.

[0003] However, hula hooping has a relatively high entry barrier, requiring a certain level of coordination, waist control, and core strength. For beginners, the elderly, or those with weaker physical conditions, mastering the continuous rotation and keeping the hula hoop from falling is not easy, and it's not suitable for space-constrained home settings. Traditional hula hooping demands a high level of body control, rhythm, and basic core strength, making it difficult for many beginners to grasp the rhythm, leading to interruptions, incorrect movements, or muscle strain. While some seated fitness machines on the market attempt to simulate this exercise, most have a simple structure, failing to accurately replicate natural waist twisting movements and lacking adaptation mechanisms for different user abilities. Furthermore, most of these machines offer limited training methods and do not allow for variation in the target muscle groups.

[0004] Therefore, there is an urgent need for fitness equipment that can simulate the core effects of hula hoop exercise, while being more adaptable, safer to train, easier to use, and applicable to more body parts, in order to meet the daily exercise needs of a wider range of people.

[0005] Therefore, we propose a fitness device that mimics the motion of a hula hoop. Utility Model Content

[0006] The purpose of this invention is to provide a fitness device that mimics hula hoop movement, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fitness device that mimics hula hoop movement, comprising a base plate and a seat plate. The base plate and the seat plate are connected by a composite mechanism composed of multiple bearings to form a swinging connection. The seat plate maintains a constant orientation when swinging relative to the base plate, thus mimicking the process of hula hoop movement. It should be noted that although it is named a seat plate in this application, it can be other parts in actual use.

[0008] Preferably, an airbag is installed at the bottom of the base plate, and the airbag is connected to an air valve and an air pump in sequence. The base plate is also equipped with a main control drive board and a power supply. The base plate is deflected by the expansion and contraction of the airbags at different positions, thereby simulating the asymmetrical movement of the human body when swinging.

[0009] Preferably, the seat plate is also detachably connected to a massage ball to provide a squeezing massage function.

[0010] Preferably, one or both surfaces of the base plate or seat plate are covered with a decorative protective layer to improve comfort and protect the equipment.

[0011] Preferably, the composite mechanism includes a first bearing, a connecting component, and a second bearing; Multiple first bearings are arranged in an array on the upper side of the base plate. Second bearings are connected to the first bearings via adapters. The rotation centers of the first and second bearings do not coincide, thereby mimicking the motion of a hula hoop.

[0012] Preferably, the base plate is provided with a drive motor for driving the rotation of the central disk, and a second bearing connected to the base plate is also installed at the eccentric position of the central disk, thereby realizing the function of electric assisted motion.

[0013] Preferably, a thrust bearing is installed on the central disk and the adapter, located outside the second bearing, to improve stability.

[0014] Preferably, a friction wheel is provided between the central disk and the adapter to make the force application more uniform.

[0015] Preferably, the friction wheel and the adapter are provided with mating grooves to provide a stable transmission process.

[0016] Preferably, the seat plate is equipped with a pressure switch, which can stop the operation in a timely manner, making it safer and more reliable.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model realizes the swinging motion of the seat plate through a non-concentric bearing and motor structure, thereby imitating the hula hoop movement process. With the waist rotation drive as the main form, it has a good trunk exercise effect. The technical solution of this application allows users to sit on the seat plate when using it. Compared with the traditional hula hoop, there is no need to grasp the rhythm of the movement and the requirements for body control are not high. Users can complete standardized movements in a seated position, effectively reducing the threshold of use. It is especially suitable for people with weak physical fitness, people in the rehabilitation period, and places with limited space. In addition, this application provides a solution that uses a drive motor as the core drive source, which can provide the effect of active or assisted movement. By adjusting the state, speed and other parameters of the drive motor, it is possible to achieve precise matching of different training rhythms.

[0018] Users can choose different exercise intensities, rhythms, and trajectory patterns according to their own abilities to achieve personalized training that is "different for each person". They can also choose different exercise parts to make the machine multi-purpose. In addition, it is equipped with a controllable airbag structure that can simulate the asymmetrical displacement of the human body during dynamic waist twisting movements. At the same time, the airbag structure can also effectively buffer the impact force during the swinging process and improve comfort. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-15 This utility model provides a technical solution: a fitness device that mimics hula hoop movement, including a base plate 1 and a seat plate 2. The seat plate 2 is the part that contacts the human body and is located on the upper layer; the base plate 1 is the part that contacts the external load and is located on the lower layer. The shapes of the base plate 1 and the seat plate 2 are not particularly limited and can be freely combined. The embodiments of this application are mainly circular.

[0023] One or both surfaces of the base plate 1 or seat plate 2 are covered with a decorative protective layer. This layer can be made of materials such as leather or fabric, serving both protective and tactile / sitting comfort purposes. Figure 1 and 2 The textured part on it.

[0024] The base plate 1 and the seat plate 2 are connected by a composite mechanism composed of multiple bearings to form a swinging connection. Specifically, the swinging process is achieved by the eccentric combination of the bearings, and the seat plate 2 maintains the same orientation when swinging relative to the base plate 1, which also conforms to the user's sitting posture.

[0025] The technical solution provided in this application has a low barrier to entry and occupies little space, making it very suitable for use in space-constrained places. In addition, it should be noted that the training of this application is not limited to sitting posture, but can also be applied to other parts of the human body. For example, the feet, palms, waist, abdomen, back and other parts can be contacted with the seat board 2 to swing and exercise the corresponding parts, thereby achieving multi-purpose use. Other parts of this application are based on sitting posture, which does not mean that it is impossible to exercise other parts of the body.

[0026] Specifically, an airbag 5 is installed at the bottom of the base plate 1. The airbag 5 is sequentially connected to an air valve 502 and an air pump 501. Furthermore, a main control drive board 12 and a power supply unit 11 are also installed on the base plate 1. Figure 3 As shown, the airbag 5 is installed on the bottom surface of the base 1, and the material covering the surface is required to have the ability to deform elastically so that the airbag 5 does not affect its operation when it is inflated, such as elastic fabric, etc. Power supply component 11 can be as follows Figure 4 The rechargeable battery (with charging module and interface, mature technology will not be described in detail) is installed in the position, or the power is connected by an external cable. At the same time, the base plate 1 also provides an installation position for the main control drive board 12. In order to facilitate control, this application also includes a controller 14, since the power supply, air pump 501, etc. are all installed on the base plate 1.

[0027] In practice, the circuit nodes on the base plate 2 only oscillate in a single turn relative to the circuit nodes on the base plate 1 during operation, and will not rotate continuously or become entangled. Therefore, the controller 14 can be fixedly placed on the base plate 2 and connected to the main control drive board 12 via wired connection. However, this is not convenient in actual operation. Therefore, the controller 14 is movably set on the upper base plate 2, preferably using a magnetic attraction method (such as setting magnets at the bottom of the controller 14 and the corresponding positions on the base plate 2 to attract each other), so as to facilitate the user to pick it up and perform corresponding control. The controller 14 and the main control drive board 12 communicate wirelessly, which requires the main control drive board 12 to be a development board with a wireless control solution, such as a development board with WIFI, Bluetooth and other functions. Since there are many existing publicly available technical solutions and commercially available products for this requirement, we will not limit the model or elaborate on its structure and principle. For example, the ESP32-C3 model development board can be used, which comes with multiple input / output interfaces (which can be added to control external air pumps, etc.); or the Arduino Nano development board, which is small in size and has wireless signal communication and other related functions.

[0028] Specifically, a massage ball 3 can also be detachably connected to the seat plate 2, such as... Figure 7 The upper surface of the seat plate 2 has a fixing hole 203 and multiple positioning holes 204 corresponding to the position of a massage ball 3. The bottom of the corresponding massage ball 3 is provided with a fixing pin 301 and multiple positioning pins 302, which are positioned and fixed by elastic interference fit. When different massage balls 3 need to be replaced, they can be easily removed and replaced. The surface covering material of the seat plate 2 can be pre-drilled with holes without affecting the installation.

[0029] Specifically, in order to realize the swinging process of the seat plate 2 on the base plate 1 in the shape of a hula hoop, the composite mechanism includes a first bearing 901, a connector 902, and a second bearing 903. Three first bearings 901 are arranged in an array on the upper side of the base plate 1. The first bearings 901 are connected to the second bearings 903 via adapters 902. The second bearings 903 are connected to the base plate 2.

[0030] Common sense dictates that a typical bearing consists of two parts that can rotate relative to each other. In the context of this application, for example... Figure 9 As shown, the two parts of the three first bearings 901 that can rotate relative to each other are respectively connected to the base plate 1 (e.g., Figure 9 The adapter 902 is connected by an interference fit (or by other fasteners such as screws). The adapter 902 can rotate on the first bearing 901. The two parts of the second bearing 903 that can rotate relative to each other are connected to the adapter 902 and the base plate 2 respectively (the connection can be made by fasteners or by interference fit).

[0031] It is important to note that the rotation centers of the first bearing 901 and the second bearing 903 do not coincide, which is necessary to achieve the swinging process that mimics a hula hoop, while maintaining the user's orientation while seated.

[0032] It should also be noted that the second bearing 903 is preferably an angular contact bearing, which can accommodate the swinging of the inner and outer rings of the bearing within a certain range. The embodiment using this solution can adapt to some slight swinging changes that occur when the user exercises the waist twisting.

[0033] The above results enable users to exercise using their own abdominal and back muscles, and on this basis, an electrically powered structure can be added to provide active / assisted exercise methods.

[0034] Specifically, the base plate 1 is equipped with a drive motor 4 that drives the central disk 401 to rotate, and a second bearing 903 connected to the base plate 2 is also installed at the eccentric position of the central disk 401. The drive motor 4 is electrically connected to the main control drive board 12 (through which it provides power, controls forward and reverse rotation and speed, all of which can be controlled by existing main control boards such as the ESP32-C3 model, which can meet the control requirements of this application), and can drive the external central disk 401 to rotate. The purpose and structure of the central disk 401 are similar to those of the first bearing 901 mentioned above, except that it can output power and perform fine motion control.

[0035] Since the load-bearing capacity of angular contact bearings is limited, specifically, a thrust bearing 904 is installed on the center disk 401 and the adapter 902 and located outside the second bearing 903. An elastic groove 9021 is opened around the adapter 902 and the center disk 401. like Figure 6As shown, a sealing plate 201 adapted to the shape of the adapter 902 and the center plate 401 is provided at the corresponding position at the bottom of the base plate 2, and a connecting post 202 adapted to the shape of the outer ring of the second bearing 903 is provided at the corresponding position at the bottom of the base plate 2.

[0036] During installation, the sealing plate 201 is pressed downwards and deformed through the elastic groove 9021 to insert into the adapter 902 to complete the connection. This serves to connect with the adapter 902 and prevent the thrust bearing 904 from moving outwards. At the same time, the connecting column 202 is also connected to the second bearing 903 (the connection is an interference fit). The sealing plate 201 and the bottom of the base plate 2 can be integrally formed or glued. In addition, the bottom of the sealing plate 201 can be integrally formed with a slight outward protrusion to connect with the flanges on both sides of the elastic groove 9021 (such as...). Figure 6 As shown, a compression fit is formed, further improving safety and stability.

[0037] Additionally, an unnecessary structure is added: a fixing post 101 is integrally formed at the center of the base plate 1 where the first bearing 901 is mounted. An auxiliary bearing 102 is also fitted onto the fixing post 101, and an interference fit is formed between the auxiliary bearing 102 and the adapter 902. Furthermore, as... Figure 8 An auxiliary screw 103 is engaged on the fixed post 101 to provide further stability. It should be noted that the first bearing 901, the auxiliary screw 103, the auxiliary bearing 102 and the fixed post 101 are all concentrically arranged and do not affect the rotation of the adapter 902.

[0038] Specifically, protective silicone rings 10 are installed on the upper side of the base plate 1 and the lower side of the seat plate 2. The installation method can be achieved by snapping or gluing based on their shape.

[0039] In the above scheme, the power source is concentrated in the central area. In order to improve stability and balance, and considering the overall volume, an additional scheme is added to the above embodiment. A friction wheel 6 is provided between the central disk 401 and the adapter 902. The friction wheel 6 is installed on the base plate 1 by screws (with small bearings to reduce friction, conventional means). The rotational power of the central disk 401 is transmitted outward by the transmission of the friction wheel 6.

[0040] like Figure 12 The equivalent diagram shown has the same dimensions for the friction wheel 6 and the adapter 902. Due to the size limitations of the existing motor and the requirements of the transmission structure, the actual size of the center disk 401 cannot be smaller. In the actual prototyping, the size of the center disk 401 is larger, and no special restrictions are placed on the size of the center disk 401. In actual operation, the friction wheel 6 and the center disk 401 transmit power through close friction. The two can slide relative to each other, and the friction slippage is used to make up for the difference in the transmission ratio, so that a 1:1 transmission is still achieved in the end.

[0041] The friction wheel 6 and the adapter 902 are provided with mating grooves (to prevent slippage between them), as shown in the schematic diagram. Figure 13 As shown, to achieve good transmission and frictional sliding, the outer surface of the center plate 401 (especially the transmission side surface) is made of PPS material, the surface of the friction wheel 6 in the middle position is made of PU material, and the outermost side of the adapter 902 in contact is made of POM material. In addition, a limiting clamp 13 that limits the center plate 401 and the adapter 902 can be installed at the bottom of the base plate 2 by screws or other fasteners to improve stability.

[0042] The base plate 2 is equipped with a pressure switch 7, which is electrically connected to the main control drive board 12. Similar to the above, due to the structural reasons of this application, in actual operation, the circuit node on the base plate 2 only swings in a single circle relative to the circuit node on the base plate 1, and will not rotate continuously and become entangled. Therefore, the circuit of the pressure switch 7 can actually be directly electrically connected to the main control drive board 12 through a cable.

[0043] Pressure switch 7 is a pre-activated switch; according to the settings, the drive motor 4 will only operate when pressure switch 7 is pressed and triggered. This allows the user to easily stop the operation by simply getting up in case of an emergency, improving safety. Additionally, as... Figure 14 As shown, a cover plate 8 is movably disposed above the pressure switch 7 and under the decorative protective layer. The tension of the decorative protective layer is required not to affect the normal use of the pressure switch 7.

[0044] like Figure 1 As shown, the controller 14 has multiple buttons that, through a pre-set program, control the forward and reverse rotation, speed, and number of revolutions of the drive motor 4. By controlling the opening and closing of air valves 502 at different positions in conjunction with the operation of air pump 501, airbags 5 at different positions can be inflated, thereby tilting the base plate 1 to simulate asymmetrical situations during swinging. The flexible structure of the airbags 5 also effectively buffers the impact force during swinging, improving comfort. All of these functions are pre-programmed into the main control driver 12, eliminating the need for tedious manual adjustments. Different buttons can have different functions, for example... First: Press the button once, and the motor will rotate continuously at a certain speed; Press twice, and the motor will continuously reverse at a certain speed; The second, third, fourth... are used as gear shifting and timer settings, respectively.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
