Description

Technical Field

[0001] This utility model relates to the field of passive exercise equipment, and in particular to a bidirectional rhythmic device. Background Technology

[0002] With the improvement of people's living standards and the increasing attention to health, various fitness and rehabilitation equipment are emerging to meet the needs of different groups for physical exercise, relaxation, and rehabilitation treatment. Among them, the rhythmic chair, as an innovative health device, has shown significant advantages in promoting blood circulation, relieving muscle fatigue, and improving physical function due to its unique rhythmic function, and has gradually gained widespread attention from the market and the favor of consumers.

[0003] Traditional kinetic chairs typically only offer unidirectional kinetic movement, usually either vertical or horizontal. While unidirectional kinetic movement can simulate natural human movement to some extent and provide certain health benefits, this single-directional mode has significant limitations. In daily life and exercise, the body experiences multi-directional and multi-dimensional combined forces on various parts. Unidirectional kinetic movement cannot comprehensively and realistically simulate this complex mechanical environment, failing to fully meet the body's need for comprehensive stimulation and exercise, thus limiting the potential of kinetic chairs in enhancing health.

[0004] Simply stacking a vertical vibrator on a horizontal vibrating platform often results in an excessively high center of gravity, leading to poor stability and safety hazards during high-speed vibrations. Secondly, the transmission paths of vertical and horizontal movements interfere with each other, making the motion trajectory uncontrollable and making it difficult to produce pure and directional composite vibrations, thus affecting the user experience and effectiveness. Furthermore, this simple stacking forces the user's back, legs, and other body parts to endure severe vertical vibrations along with the hips during operation. This not only fails to provide stable support for the upper body but may also cause discomfort or even injury with prolonged use.

[0005] Therefore, there is an urgent need in this field for a new type of bidirectional rhythmic device that can effectively and stably integrate vertical and horizontal rhythms, and solve problems such as motion interference, poor stability, and insufficient comfort in existing technologies. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a bidirectional rhythm device. By cleverly combining horizontal and vertical rhythm structures, it realizes multi-directional composite rhythm without interference, effectively solves the shortcomings of the prior art, and improves the overall performance and market competitiveness of the product.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A two-way rhythmic device includes a frame for receiving a user's body, and further includes: A horizontal rhythmic structure for outputting horizontal rhythmic motion includes a horizontal rhythmic base, a horizontal rhythmic output component, and a horizontal rhythmic drive mechanism. The horizontal rhythmic drive mechanism is attached to the horizontal rhythmic base, and the horizontal rhythmic output component and the horizontal rhythmic drive mechanism are drively connected. The frame is attached to the horizontal rhythmic output component to obtain horizontal rhythmic motion. A vertical rhythm structure for outputting vertical rhythm has a vertical rhythm base, a vertical rhythm output component, and a vertical rhythm drive mechanism. The vertical rhythm base is attached to the frame, the vertical rhythm drive mechanism is attached to the vertical rhythm base, and the vertical rhythm output component and the vertical rhythm drive mechanism are connected in a transmission manner. The vertical rhythm output component is configured to receive the user's buttocks and perform vertical rhythm massage, and a clearance is formed between the frame and the vertical rhythm output component to prevent them from colliding.

[0008] Furthermore, the frame also has an installation space, and the vertical pulsating base is suspended in the installation space by a suspension member.

[0009] Furthermore, it also includes a back frame for supporting the user's back, the bottom of which is movably attached to one side of the frame via a hinge, and the frame is provided with a back frame drive push rod for driving the back frame to adjust its angle.

[0010] Furthermore, a back frame linkage mechanism is provided between the back frame and the frame body. The frame body includes a base frame and a movable frame. The base frame is attached to the horizontal rhythm output component. The movable frame is attached to the base frame through a sliding mechanism. The back frame is movably attached to one side of the movable frame. The two ends of the back frame drive push rod are respectively connected to the base frame and the movable frame to drive the movable frame to move relative to the base frame and to adjust the angle of the back frame through the back frame linkage mechanism.

[0011] Furthermore, the sliding mechanism includes a slide rail attached to the bottom frame and a sliding block attached to the movable frame, wherein the sliding block is slidably limited within the slide rail.

[0012] Furthermore, the back frame linkage mechanism includes a first link, a second link, and a third link. One end of the first link is hinged to the bottom of the back frame, and the other end is rotatably connected to one end of the second link. The middle part of the second link is hinged to the movable frame, and the other end is rotatably connected to one end of the third link. The other end of the third link is hinged to the bottom frame.

[0013] Furthermore, it also includes a calf support for supporting the user's lower legs, the top of which is movably attached to the other side of the movable frame via a hinge, and the movable frame is equipped with a calf support drive rod for driving the calf support to adjust its angle.

[0014] Furthermore, the lower leg frame is also equipped with a support plate that can move relative to the lower leg frame. A lower leg frame linkage mechanism is configured between the lower leg frame and the moving frame, and a support plate linkage mechanism is configured between the support plate and the moving frame. The lower leg frame drive push rod drives the lower leg frame to rotate relative to the moving frame through the lower leg frame linkage mechanism, and drives the support plate to move relative to the lower leg frame through the support plate linkage mechanism.

[0015] Furthermore, the horizontal rhythm output component includes a linear sliding mechanism and a bidirectional inertia suppression mechanism disposed on the linear sliding mechanism. The bidirectional inertia suppression mechanism is configured to suppress sudden acceleration changes in the frame that cause the user to slide relative to the frame.

[0016] Furthermore, the horizontal rhythmic structure also has an amplitude adjustment mechanism, which includes an amplitude adjustment drive motor and an amplitude adjustment transmission component.

[0017] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model's bidirectional rhythmic device innovatively integrates horizontal and vertical rhythmic structures, breaking through the limitations of traditional rhythmic chairs that only possess single-directional rhythmic function. In daily human activities and exercise, various parts of the body are subjected to complex forces acting in multiple directions and dimensions. This device, by simultaneously outputting horizontal and vertical rhythms, can more comprehensively and realistically simulate the natural movement state of the human body. This complex rhythm can simultaneously stimulate muscle groups and the nervous system in different parts of the body, promoting blood circulation, accelerating metabolism, effectively relieving muscle fatigue, and enhancing muscle strength and flexibility. Compared to single-directional rhythms, complex rhythms can exercise and relax the body from multiple dimensions, greatly improving health benefits and providing users with a higher quality and more efficient health experience, meeting the body's need for comprehensive stimulation and exercise.

[0018] 2. In this utility model, the vertical rhythmic base is suspended within the installation space of the frame via a suspension connector. This design not only rationally arranges the internal space of the device and lowers the overall center of gravity, but also effectively enhances the stability of the device during high-speed rhythmic motion, reducing swaying and tilting caused by an unstable center of gravity, greatly reducing safety hazards and ensuring user safety during use. Simultaneously, through a reasonable structural design and transmission connection method, motion interference between horizontal and vertical rhythmic motions is avoided, ensuring that the two rhythms can operate independently and stably, producing a pure and directional composite rhythm, improving the reliability and stability of the device, and providing users with a safer and more comfortable operating environment.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0027] Example: Please see Figure 1 and Figure 2 The bidirectional rhythm device provided by this utility model includes: a frame 10 for receiving the user's body, a horizontal rhythm structure 20 for outputting horizontal rhythm, and a vertical rhythm structure 30 for outputting vertical rhythm.

[0028] The horizontal rhythm structure 20 has a horizontal rhythm base 21, a horizontal rhythm output component 22, and a horizontal rhythm drive mechanism 23. The horizontal rhythm drive mechanism 23 is attached to the horizontal rhythm base 21. The horizontal rhythm output component 22 and the horizontal rhythm drive mechanism 23 are connected in a transmission manner. The frame 10 is attached to the horizontal rhythm output component 22 to obtain horizontal rhythm.

[0029] The vertical rhythm structure 30 has a vertical rhythm base 31, a vertical rhythm output component 32, and a vertical rhythm drive mechanism 33. The vertical rhythm base 31 is attached to the frame 10, the vertical rhythm drive mechanism 33 is attached to the vertical rhythm base 31, and the vertical rhythm output component 32 and the vertical rhythm drive mechanism 33 are connected in a transmission manner.

[0030] The vertical rhythm output component 32 is configured to accommodate the user's buttocks and perform vertical rhythm massage, and a clearance P is formed between the frame 10 and the vertical rhythm output component 32 to prevent them from colliding.

[0031] Based on the above structure, during use, the user sits on the vertical rhythmic output component 32. The shape of the vertical rhythmic output component 32 is ergonomically designed to ensure full contact with the user's buttocks, providing a comfortable massage experience. The clearance P between the frame 10 and the vertical rhythmic output component 32 prevents collisions during rhythmic movement, ensuring stable operation of the device. See also Figure 3 In this embodiment, the horizontal rhythm drive mechanism 23 includes a horizontal rhythm drive motor 231 and a horizontal rhythm transmission component 232. The specific structure and driving method of the horizontal rhythm transmission component 232 have been previously applied for and will not be described in detail in this application.

[0032] See Figure 4 In this embodiment, the vertical rhythm drive mechanism 33 includes a vertical rhythm drive motor 331 and a vertical rhythm transmission component 332. The specific structure and driving method of the vertical rhythm transmission component 332 have been previously applied for and will not be described in detail in this application.

[0033] When the user sits on the frame 10, the horizontal rhythm drive motor 231 and the vertical rhythm drive motor 331 are activated respectively. The horizontal rhythm drive motor 231 drives the horizontal rhythm output component 22 to reciprocate in the horizontal direction through the horizontal rhythm transmission component 232, thereby giving the frame 10 horizontal rhythm. At the same time, the vertical rhythm drive motor 331 drives the vertical rhythm output component 32 to reciprocate in the vertical direction through the vertical rhythm transmission component 332, providing vertical rhythm massage to the user's buttocks. By simultaneously outputting rhythms in both the horizontal and vertical directions, the bidirectional rhythm device of this invention can more comprehensively and realistically simulate the natural movement state of the human body, providing users with a comprehensive exercise and relaxation experience.

[0034] See Figure 2 and Figure 4To further optimize the structural layout and stability of the device, this invention provides an installation space T on the frame 10, within which the vertical rhythmic base 31 is suspended via a suspension member 34. The suspension member 34 can be an L-shaped suspension rod, which can be positioned around the vertical rhythmic base 31 or in pairs on opposite sides of the base. This design not only rationally arranges the internal space of the device and lowers the overall center of gravity, but also effectively enhances the stability of the device during high-speed rhythmic motion, reducing swaying and tilting caused by an unstable center of gravity, significantly reducing safety hazards and ensuring user safety during use.

[0035] See Figure 5 and Figure 6 To provide more comprehensive body support, this utility model also includes a back frame 40 for supporting the user's back. The bottom of the back frame 40 is movably attached to one side of the frame body 10 via a back frame hinge 41, and the frame body 10 is equipped with a back frame drive push rod 42 for adjusting the angle of the back frame 40. The specific structure of the back frame hinge 41 is prior art and will not be described in detail in this application.

[0036] Furthermore, in this embodiment, a back frame linkage mechanism 43 is provided between the back frame 40 and the frame body 10. The frame body 10 includes a bottom frame 11 and a movable frame 12. The bottom frame 11 is attached to the horizontal rhythmic output component 22, and the movable frame 12 is attached to the bottom frame 11 via a sliding mechanism 13. The back frame 40 is movably attached to one side of the movable frame 12. The two ends of the back frame drive push rod 42 are respectively connected to the bottom frame 11 and the movable frame 12 to drive the movable frame 12 to move relative to the bottom frame 11, and the back frame linkage mechanism 43 drives the back frame 40 to adjust its angle.

[0037] See Figure 7 The sliding mechanism 13 includes a slide rail 131 attached to the bottom frame 11 and a sliding block 132 attached to the movable frame 12. The sliding block 132 is slidably limited within the slide rail 131 to ensure that the movable frame 12 can slide smoothly on the bottom frame 11.

[0038] See Figure 5The back frame linkage mechanism 43 includes a first link 431, a second link 432, and a third link 433. One end of the first link 431 is hinged to the bottom of the back frame 40, and the other end is rotatably connected to one end of the second link 432. The middle part of the second link 432 is hinged to the movable frame 12, and the other end is rotatably connected to one end of the third link 433. The other end of the third link 433 is hinged to the bottom frame 11, and the third link 433 is curved to accommodate the angle adjustment requirements of the back frame 40. When the back frame drive push rod 42 pushes the movable frame 12 to move relative to the bottom frame 11, the back frame 40 is driven to rotate around the back frame hinge 41 through the transmission action of the back frame linkage mechanism 43, thereby realizing the angle adjustment of the back frame 40 and meeting the different usage needs of users.

[0039] See Figure 5 and Figure 6 To provide more comprehensive leg support, this invention also includes a calf support 50 for supporting the user's lower legs. The top of the calf support 50 is movably attached to the other side of the movable frame 12 via a calf support hinge 51. The movable frame 12 is equipped with a calf support drive push rod 52 for adjusting the angle of the calf support 50. The specific structure of the calf support hinge 51 is prior art and will not be described in detail in this application.

[0040] Furthermore, in this embodiment, a support plate 53 that can move relative to the lower leg frame 50 is also provided on the lower leg frame 50. A lower leg frame linkage mechanism 54 is provided between the lower leg frame 50 and the movable frame 12, and a support plate linkage mechanism 55 is provided between the support plate 53 and the movable frame 12. The lower leg frame drive push rod 52 drives the lower leg frame 50 to rotate relative to the movable frame 12 through the lower leg frame linkage mechanism 54, and drives the support plate 53 to move relative to the lower leg frame 50 through the support plate linkage mechanism 55. The specific structures of the lower leg frame linkage mechanism 54 and the support plate linkage mechanism 55 are prior art and will not be described in detail in this application.

[0041] In this embodiment, when the lower leg support drive push rod 52 pushes the lower leg support 50 to rotate, the lower leg support linkage mechanism 54 and the support plate linkage mechanism 55 drive the support plate 53 to move relative to the lower leg support 50, thereby realizing the synchronous adjustment of the lower leg support 50 and the support plate 53, providing users with more comfortable leg support.

[0042] See Figure 3In this embodiment, the horizontal rhythm output component 22 includes a linear sliding mechanism 221 and a bidirectional inertia suppression mechanism 222. The linear sliding mechanism 221 is used to realize the horizontal rhythm of the frame 10. The bidirectional inertia suppression mechanism 222 is disposed on the linear sliding mechanism 221 and is configured to suppress the user from sliding relative to the frame 10 due to sudden acceleration changes of the frame 10. This mechanism can monitor the acceleration changes of the frame 10 in real time through sensors and adjust the output torque of the drive motor through the control system, thereby achieving precise control of acceleration, avoiding the user from sliding due to inertia, and improving the safety and comfort of use. The specific structures of the linear sliding mechanism 221 and the bidirectional inertia suppression mechanism 222 have been previously applied for and will not be described in detail in this application.

[0043] See Figure 3 To further optimize the horizontal rhythm effect, the horizontal rhythm structure 20 of this utility model also includes an amplitude adjustment mechanism 24. The amplitude adjustment mechanism 24 includes an amplitude adjustment drive motor 241 and an amplitude adjustment transmission component 242. The specific structure of the amplitude adjustment transmission component 242 has been previously applied for and will not be detailed here. The amplitude adjustment drive motor 241 is attached to the horizontal rhythm base 21 and is connected to the horizontal rhythm output component 22 via the amplitude adjustment transmission component 242. When the amplitude adjustment drive motor 241 operates, it drives the horizontal rhythm drive mechanism 23 to change its amplitude of motion through the amplitude adjustment transmission component 242, specifically changing the transmission amplitude of the horizontal rhythm transmission component 232, thereby achieving adjustment of the horizontal rhythm amplitude to meet different user needs.

[0044] See also Figure 3 To protect the various components of the horizontal rhythmic structure 20, this invention also includes a protective frame 25 on the horizontal rhythmic base 21 to protect the horizontal rhythmic output component 22, the horizontal rhythmic drive mechanism 23, the amplitude modulation output component, and the amplitude modulation drive mechanism 24. The protective frame 25 is made of a sturdy material, such as metal or high-strength plastic, and its shape and size are designed according to the various components of the horizontal rhythmic structure 20. It can be mounted on top of these components to avoid interference with other components on top. The protective frame 25 not only prevents damage to the horizontal rhythmic structure 20 from external objects but also prevents users from contacting these components during use, improving safety.

[0045] This utility model's bidirectional rhythmic device cleverly combines horizontal and vertical rhythmic structures to achieve interference-free multidirectional composite rhythms, effectively solving problems such as motion interference, poor stability, and insufficient comfort in existing technologies. By rationally arranging the internal space, the overall center of gravity is lowered, enhancing the device's stability and providing a safer and more comfortable user environment. Simultaneously, the inclusion of a back frame and leg supports provides comprehensive body support, meeting diverse usage needs. The design of the amplitude adjustment mechanism and protective frame further optimizes the device's performance, improving its reliability and lifespan. This utility model's bidirectional rhythmic device has broad market prospects and application value, providing strong support for people's healthy living.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
