Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a composite rhythmic slow rocking device and a massage chair. Background Technology

[0002] The rhythmic function of a massage chair utilizes advanced motion simulation technology to accurately reproduce the body's natural movement trajectories, such as the up-and-down motion of jogging or the back-and-forth swaying of horseback riding. This rhythmic movement pattern is achieved through a sophisticated mechanical structure, including rhythmic up-and-down vibrations, side-to-side swaying, and forward-and-backward movement. These combined movements effectively stimulate the user's muscle groups, promote accelerated blood circulation throughout the body, and enhance cardiopulmonary function, achieving fitness effects similar to aerobic exercise.

[0003] The slow rocking function is another important relaxation mode. It simulates the slow, gentle rocking motion of a baby cradle, oscillating rhythmically at a frequency of 6-25 times per minute. This gentle rocking stimulates the vestibular system, producing a sense of security similar to being held in a mother's arms. It helps to quickly relax tense emotions, relieve mental stress, and has a significant effect on improving insomnia symptoms and enhancing sleep quality.

[0004] However, market research has revealed that the vast majority of massage chairs currently on the market suffer from limited functionality. They either only offer rhythmic massage or a slow rocking mode, failing to intelligently switch between or organically integrate these two distinct exercise modes. This technological limitation severely restricts the overall user experience of massage chairs, failing to fully realize their intended relaxation effects and limiting their application value in the health and wellness field.

Detailed Implementation

[0034] The following is combined with Figures 1-13 This utility model will be described in detail.

[0035] A composite rhythmic slow rocking device includes a base 10 and a platform 20. The base 10 is provided with a first rocking component 30 and a second rocking component 40. The output end of the first rocking component 30 is hinged to a first end of the platform 20, and the output end of the second rocking component 40 is hinged to a second end of the platform 20. The platform 20 is driven to rock by the first rocking component 30 and the second rocking component 40, and the rocking amplitude of the platform 20 driven by the first rocking component 30 is greater than the rocking amplitude of the platform 20 driven by the second rocking component 40.

[0036] Therefore, when the first rocking component 30 works alone, the platform 20 can generate a large-amplitude rocking motion, simulating the motion trajectory in rhythm mode; when the second rocking component 40 runs independently, it brings a small and gentle slow rocking experience; and with the synergistic effect of the two components, the combined effect of compound rhythm and slow rocking can be achieved, making the motion modes of the massage chair 80 more diverse, meeting the personalized needs of different users, and significantly improving the functionality and comfort of the massage chair 80.

[0037] like Figure 2 and Figure 3 As shown, the first rocking assembly 30 includes a first drive shaft 301, with both ends of the first drive shaft 301 rotatably connected to the base 10. The first drive shaft 301 has a first connecting rod assembly at both ends. The first connecting rod assembly includes a first connecting member 3021 and a second connecting member 3022 hinged to each other. The end of the first connecting member 3021 away from the second connecting member 3022 is fixedly connected to the first drive shaft 301, and the end of the second connecting member 3022 away from the first connecting member 3021 is hinged to the platform 20. Further, as... Figure 3 As shown, the platform 20 has connecting posts 201 on both sides, and the ends of the two second connecting pieces 3022 that are away from the first connecting piece 3021 are hinged to the corresponding connecting posts 201.

[0038] like Figure 2 , Figure 3 as well as Figure 4 As shown, the second rocking assembly 40 includes a second drive shaft 401, both ends of which are rotatably connected to the base 10, and both ends of the second drive shaft 401 are provided with connecting shafts 4012. The axis of the connecting shaft 4012 is not coaxial with the axis of the second drive shaft 401, and the connecting shaft 4012 is rotatably connected to the platform 20.

[0039] like Figure 4 and Figure 5 As shown, the distance between the axis of the first drive shaft 301 and the axis between the first connector 3021 and the second connector 3022 is greater than the distance between the axis of the second drive shaft 401 and the axis of the connecting shaft 4012, that is, L1 is greater than L2, so that the swing amplitude of the platform 20 driven by the first swing component 30 is greater than the swing amplitude of the platform 20 driven by the second swing component 40.

[0040] The first rocking assembly 30 further includes a first driving device 303, which is driven by the first drive shaft 301. The second rocking assembly 40 further includes a second driving device 402, which is driven by the second drive shaft 401. Further, the first driving device 303 includes a first drive motor 3031 and a reduction gear assembly. The input end of the reduction gear assembly is connected to the output end of the first drive motor, and the output end of the reduction gear is driven by the first drive shaft 301. By reducing the output speed of the first drive device 303 through the reduction gear assembly, the first drive shaft 301 drives the platform 20 to rock at a slower speed, thus achieving a slow rocking function. Since the second rocking assembly 40 is used to achieve a rhythmic rocking function, the platform 20 rocks faster during rhythmic rocking. Because the distance between the axis of the connecting shaft 4012 and the axis of the second drive shaft 401 is short, the rotational speed of the connecting shaft 4012 around the axis of the second drive shaft 401 will not be too high. Therefore, the drive motor can be directly driven by the second drive shaft 401 without the need for a reduction gear assembly.

[0041] like Figure 2 and Figure 3 As shown, a first pulley 3011 is provided in the middle of the first drive shaft 301, and a first drive device 303 is connected to the first pulley 3011 by belt drive; a second pulley 4011 is provided in the middle of the second drive shaft 401, and a second drive device 402 is connected to the second pulley 4011 by belt drive.

[0042] like Figure 3 As shown, the base 10 is provided with a first bearing 501 and a second bearing 502. The two ends of the first drive shaft 301 are connected to the inner ring of the first bearing 501, the two ends of the second drive shaft 401 are connected to the inner ring of the second bearing 502, and the platform 20 is provided with a third bearing 503. The connecting shaft 4012 is connected to the inner ring of the third bearing 503. The function of the bearing is to reduce the friction between the two components.

[0043] This embodiment also proposes a composite rhythmic slow rocking device with a single motor configuration, such as... Figure 6 and Figure 7 As shown. Specifically, the compound rhythmic slow rocking device includes a dual-head drive motor 60, with its two output ends respectively connected to a first drive shaft 301 and a second drive shaft 401. Further, the two output ends of the dual-head drive motor 60 are connected to the first drive shaft 301 and the second drive shaft 401 via belt drives. Compared to the previous description, using a dual-head drive motor 60 reduces one drive unit, effectively lowering production costs and simplifying the structural layout.

[0044] This embodiment also proposes a configuration scheme with single rhythm and single slow rock, and users can choose the appropriate configuration scheme according to their actual needs to improve the applicability and economy of the product.

[0045] The single slow rocking configuration retains only the first rocking component 30 and removes the second rocking component 40, making it suitable for applications requiring only slow rocking, such as... Figure 8 and Figure 9 As shown. Specifically, a rotating shaft assembly 70 is fixedly mounted on the base 10, and the rotating end of the rotating shaft assembly 70 is rotatably connected to a third bearing 503 on the platform 20. Activating the first rocking assembly 30 causes the platform 20 to perform a rhythmic motion relative to the base 10.

[0046] The single-rhythm configuration retains only the second swing component 40 and removes the first swing component 30. This is suitable for scenarios requiring only rapid rhythmic swinging, such as... Figure 10 and Figure 11 As shown. Specifically, a rotating shaft assembly 70 is fixedly mounted on the base 10, and the rotating end of the rotating shaft assembly 70 is rotatably connected to the second connecting member 3022. Activating the second rocking assembly 40 causes the platform 20 to slowly rock relative to the base 10.

[0047] This embodiment also proposes a massage chair 80, such as Figure 12 and Figure 13 As shown, the device includes a chair frame 801 and a composite rhythmic rocking device as described above. The chair frame 801 is connected to the platform 20 to drive the chair frame 801 to rock.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
