Description

Technical Field

[0001] The present invention relates to the technical field of massage pillows, and in particular to a movement structure of a massage pillow and a massage pillow. Background Art

[0002] With the rapid development of modern society, the use of computers in work and life is very high, and transportation is also very developed. Office workers and drivers sit for a long time, which puts a lot of pressure on the cervical spine, spine, lumbar spine and other parts. This can easily lead to cervical spine injuries and other diseases, affecting normal life and work. Generally, people will put suitable pillows on car seats and home seats. Good pillows can relieve people's cervical fatigue.

[0003] However, the massage part of the existing massage pillow that contacts the human body can usually only rotate in the horizontal direction to massage the human body. For example, Chinese patent document CN213282245U discloses a trigger-type massage pillow. However, the massage part moves in only one direction, and the concave parts such as the side of the neck cannot be massaged in place, resulting in insufficient massage of the human body and poor massage experience. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and provide a movement structure of a massage pillow and a massage pillow.

[0005] The technical solution of the present disclosure is achieved as follows:

[0029] Reference Figure 1 and Figure 2 , a movement structure of a massage pillow, the movement structure comprising:

[0030] The swing rod 20 is swingably mounted on the housing 10 of the movement structure, the swing end of the swing rod 20 extends out of the movement structure, and is equipped with a massage head 22. Specifically, the swing rod 20 has a hemispherical connecting portion 21, and the hemispherical connecting portion 21 is rotatably clamped in the spherical groove 11 of the housing 10, driving the massage head 22 to rotate;

[0031] The guide rod 30 is rotatably connected to the housing 10, and has a first transmission contact surface 31 at its end. The portion of the swing rod 20 connected to the housing 10 has a second transmission contact surface 211. The first transmission contact surface 31 is rotatably connected to the second transmission contact surface 211, and the first transmission contact surface 31 is arranged obliquely; as a preferred embodiment, the second transmission contact surface 211 is arranged horizontally, and the angle between the first transmission contact surface 31 and the second transmission contact surface 211 is 5° to 15°. Figure 8 In the embodiment, the preferred angle is 10°.

[0032] A driving assembly 50, used for driving the guide rod 30 to rotate;

[0033] In the above structure, since the first transmission contact surface 31 is inclined so that the bottom of the guide rod 30 has peaks and valleys, as the driving assembly 50 rotates the guide rod 30, the positions of the peaks and valleys will continuously change with the rotation of the guide rod 30, and the first transmission contact surface 31 and the second transmission contact surface 211 are rotatably connected. In this process, the peaks will squeeze the second transmission contact surface 211, and the swing end of the swing rod 20 will swing around the center of the hemispherical connecting portion 21 by squeezing the second transmission contact surface 211, as shown in FIG. Figure 7 and Fig. 9 shown.

[0034] Furthermore, the housing 10 has limiting grooves 111 on both sides of the spherical groove 11, and both sides of the hemispherical connecting portion 21 have limiting protrusions 212, and the limiting protrusions 212 are movably and rotatably embedded in the limiting grooves 111, and the limiting grooves 111 are extended along the geometric circle of the spherical groove ball 11 surface, wherein the moving direction of the limiting protrusions 212 is as follows: Figure 7 The dotted arrow in the upper part shows the direction of rotation. Figure 7 The function of the limiting protrusion 212 and the limiting groove 111 is to ensure that the hemispherical connecting portion 21 can rotate in the spherical groove 11 while preventing the hemispherical connecting portion 21 from rotating about the central axis of the swing rod 20, so as to ensure that the angle of the massage head 22 does not change; further, the cross section of the limiting protrusion 212 is semicircular, so that the limiting protrusion 212 can rotate more smoothly in the limiting groove 111, and can rotate around the center of the cross section of the limiting protrusion 212, as shown in the dotted arrow in the lower half. Figure 7 The lower part is indicated by the dotted arrow.

[0035] A further improvement based on the above structure: the driving assembly 50 includes: a first gear 51, which is sleeved and fixed on the guide rod 30, and the rotating axis of the first gear 51 is coaxial with the rotating axis of the guide rod 30; a second gear 52, which meshes with the first gear 51; a screw rod 53, which meshes with the second gear 52; a motor 54, which is installed at the center of the shell 10 and is used to drive the screw rod 53 to rotate. When the screw rod 53 rotates, the screw rod 53 will drive the second gear 52 to rotate, thereby driving the first gear 51 to rotate. The rotation of the first gear 51 can drive the guide rod 30 to rotate, thereby realizing the swing of the massage head 22.

[0036] Preferably, the second gear 52 includes an upper gear 521 and a lower gear 522 that rotate coaxially, and the lower gear 522 is fixed below the upper gear 521, the wheel diameter of the upper gear 521 is larger than the wheel diameter of the lower gear 522, and the wheel diameter of the first gear 51 is larger than the wheel diameter of the lower gear 522; preferably, the wheel diameter ratio of the upper gear 521 to the lower gear 522 is 1.5:1, and at the same time, the lower gear 522 is meshed with the first gear 51, and the upper gear 521 is meshed with the screw rod 53. When the screw rod 53 rotates the upper gear 521, the upper gear 521 drives the lower gear 522 to rotate, thereby driving the first gear 51 to rotate, realizing the rotation of the guide rod 30, and the massage head 22 can be swung;

[0037] Based on the further improvement of the above structure, the purpose of rotating the guide rod 30 with less effort is achieved by designing the transmission ratio of the screw rod 53 and the first gear 51. Specifically, the transmission between the screw rod 53 and the first gear 51 is a reduction transmission, and the transmission ratio of the screw rod 53 and the first gear 51 is i=2; i=Zb / Za, wherein Za is the number of teeth of the first gear 51, and Zb is the number of teeth of the screw rod 53, and Za=1, Zb=2, so as to achieve the effect of rotating the guide rod 30 with less effort.

[0038] The housing 10 also has a thickened portion 12 at the opening of the spherical groove 11 to increase the transmission contact area between the housing 10 and the guide rod 30, ensuring that the guide rod 30 is not prone to shaking or shifting when rotating.

[0039] The utility model also discloses a massage pillow, in which a movement is installed. The movement adopts the movement structure of the massage pillow mentioned above. The implementation effect of the massage pillow is the same as the movement structure mentioned above, which will not be described in detail here.
