Description

Technical Field

[0001] The utility model relates to the technical field of neck care equipment, in particular to a massage pillow. Background Art

[0002] With the rapid development of modern society, computer usage is very high in both work and life, and transportation is also very developed. Office workers and drivers, for example, spend long periods of time sitting, which puts a lot of pressure on the cervical spine, spine, and lumbar spine. This can easily lead to cervical injuries and other diseases, affecting normal life and work. Generally, people place suitable pillows on car seats and home seats. A good pillow can relieve people's cervical fatigue.

[0003] However, existing massage pillows typically only rotate the massage portion that contacts the human body horizontally to provide massage. For example, Chinese patent document CN213282245U discloses a trigger-type massage pillow. However, the massage portion only moves in one direction, so recessed areas such as the sides of the neck cannot be massaged, resulting in an inadequate massage and a suboptimal massage experience.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figures 1 to 5 As shown, a massage pillow includes a pillowcase 1 and a shell 2 built into the pillowcase 1, a driving mechanism 3 is provided in the shell 2, the driving mechanism 3 includes an output shaft 31 extending to the outside of the shell 2, and also includes a massage component 4, the massage component 4 includes an adapter seat 41 and a massage head 42, the adapter seat 41 is driven to rotate by the output shaft 31, the massage head 42 is rotatably connected to the adapter seat 41, and the adapter seat 41 is provided with a first surface 411 abutting the output shaft 31, and a second surface 412 for supporting the connection of the massage head 42, the first surface 411 and the second surface 412 are arranged at an angle; the shell 2 is provided with a limiting groove 231, and the massage head 42 is provided with a limiting rod 421 embedded in the limiting groove 231.

[0026] The cooperation between the limiting rod 421 and the limiting slot 231, as well as the angular arrangement of the first surface 411 and the second surface 412, allows the massage head 42 to move in a manner that, while rotating along the output shaft 31 at a certain angle, also fluctuates in height. This allows the massage head 42 to more fully massage areas such as the neck, enhancing the massage experience. The limiting slot 231 limits the rotation angle of the massage head 42, while the cooperation between the first surface 411 and the second surface 412 drives and limits the height fluctuation of the massage head 42.

[0027] As a preferred embodiment, the first surface 411 is arranged horizontally, and the angle between the second surface 412 and the first surface 411 is 5° to 15°. Figure 4 The preferred angle is 10°, which limits the fluctuation height of the massage head 42 to prevent the fluctuation height of the massage head 42 from being too high or too low, thereby reducing the massage comfort.

[0028] The massage assembly 4 also includes a pressure plate 43. A limit rod 421 is provided on one side of the massage head 42. The massage head 42 has a massage portion on the opposite side. The pressure plate 43 is positioned above the massage head 42 and connected to the adapter 41 via screws, securing the massage head 42 to the adapter 41. During assembly, the adapter 41 is mounted on the output shaft 31, the massage head 42 is then sleeved around the outer periphery of the adapter 41, and finally locked to the adapter 41 via the pressure plate 43. This prevents the massage head 42 from detaching from the adapter 41 and facilitates inserting the limit rod 421 of the massage head 42 into the limit groove 231.

[0029] The driving mechanism 3 further includes a swing shaft 32 extending to the outside of the housing 2; and a beating assembly 5, which includes a beating member 51, one end of which is connected to the swing shaft 32, and the other end of which is rotatably connected to the upper surface of the housing 2. The beating member 51 is swung vertically at a certain angle, so that it continuously beats the shoulder area of the human body, thereby enhancing the massage experience.

[0030] The housing 2 comprises a detachably connected upper shell 21 and a lower shell 22, and the upper surface of the upper shell 21 is provided with a connecting shaft 52, which crosses the hammering piece 51. By the connecting shaft 52, the upper shell 21 and the hammering piece 51 are quickly and easily assembled.

[0031] The housing 2 further comprises a limiting member 23 having a limiting groove 231 extending in a vertical direction, and the limiting member 23 is detachably connected to the upper housing 21. By forming each component individually, the limiting groove 231 can be easily formed.

[0032] The drive mechanism 3 also includes a dual-axis motor 33, a first gear 34, and a second gear 35. The dual-axis motor 33 is internally mounted within the housing 2. The first and second gears 34, 35 mesh with each other and are rotatably connected to the housing 2. A worm 331 of the dual-axis motor 33 meshes with the first gear 34, and the second gear 35 is provided with an output shaft 31 extending from the housing 2. This allows for two massage assemblies 4, symmetrically arranged about the center of the massage pillow, and allows both massage assemblies 4 to be driven by a single dual-axis motor 33, reducing costs. Specifically, the first gear 34 is rotatably connected to the housing 2 via a first rotating shaft 39, and the second gear 35 is rotatably connected to the housing 2 via an output shaft 31. The dual-axis motor 33 ultimately drives the output shaft 31 to rotate via the first and second gears 34, 35. The lower end of the output shaft 31 is rotatably connected to the housing 2. The first rotating shaft 39 and the output shaft 31 are rotatably connected to the upper housing 21 and the lower housing 22, respectively.

[0033] The first gear 34 includes an upper gear 341 and a lower gear 342 . The upper gear 341 is engaged with the worm 331 , and the lower gear 342 is engaged with the second gear 35 , thereby reducing the overall occupied space of the driving mechanism 3 .

[0034] The driving mechanism 3 also includes a pulley group 36 and a driven rod 37. One end of the pulley group 36 is arranged on the worm 331 of the dual-axis motor 33, and the other end of the pulley group 36 is arranged on the driven rod 37. The driven rod 37 is rotatably connected to the upper shell 21 and the lower shell 22 through a plurality of bearings 38. The driven rod 37 is connected to the swing shaft 32 and drives it to swing. The two massage components 4 and the hammering component 5 are driven by a dual-axis motor 33. The utility model only requires one dual-axis motor 33 to achieve two different massage functions, thereby reducing the overall manufacturing cost.

[0035] The pulley assembly 36 includes a first pulley 361 and a second pulley 362, and a transmission belt 363 connecting the first pulley 361 and the second pulley 362. The first pulley 361 is sleeved on the worm 331, and the second pulley 362 is sleeved on the driven rod 37. The ratio of the wheel diameters of the first pulley 361 and the second pulley 362 is 1:3 to 1:6. This makes the beating speed of the beating member 51 much faster than the rotation and swing speed of the massage head 42, thereby improving the massage comfort.

[0036] The pillowcase 1 is further provided with a sponge pad 6, which is provided with a mounting groove for mounting the housing 2. The sponge pad 6 can play a buffering and shock-absorbing role.
