DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained in conjunction with specific embodiments below. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making any creative work all belong to the protection scope of the present invention.

[0032] like Figure 1-Figure 3 As shown, the present invention provides a walking movement with a massage head that can be opened and closed, comprising a frame 1, a massage movement slidably arranged on the frame 1, the massage movement comprising a housing 2 and a massage head 3 arranged on the housing 2, and the walking movement also includes a position changing mechanism:

[0033] The position changing mechanism includes at least one guide portion 111 and at least one adjustment component 4 (herein, two guide portions 111 and two adjustment components 4 are used as an example for explanation, and at this time, the corresponding two massage heads 3 can move closer to or farther from each other to perform opening and closing movements), and the guide portion 111 is arranged on the frame 1;

[0034] The adjustment assembly 4 includes a pull rod 41, a rotating disk 42, a driving member 44 and a support rod 43;

[0035] The turntable 42 is rotatably disposed in the housing 2, and one end of the pull rod 41 is connected to one end of the turntable 42;

[0036] The driving member 44 is disposed at the other end of the pull rod 41, and the driving member 44 passes through the bottom of the housing 2 and contacts the guide portion 111;

[0037] The support rod 43 is arranged at the other end of the top surface of the turntable 42, and the top of the support rod 43 is provided with a massage head 3;

[0038] When the massage movement slides on the frame 1, the driving member 44 moves along the guide part 111, the driving member 44 drives the pull rod 41 to move, the pull rod 41 drives the turntable 42 to rotate, the rotation of the turntable 42 drives the support rod 43 to rotate, so that the massage head 3 follows the support rod 43 to rotate around the rotation axis of the turntable 42, thereby changing the position of the massage head 3 on the housing 2, so that when the massage movement is moving, the position of the massage head 3 is also changing, when people lean on the massage head 3 of the massage movement, different positions of the human body can be massaged, the massage position of the human body is increased, and people have a better experience, and no additional power source is required for driving, which is more energy-saving and environmentally friendly;

[0039] When the pull rod 41 encounters an overload condition, the pull rod 41 may be deformed or the joint may become loose, thereby avoiding serious damage to the mechanism. However, if the turntable 42 is driven by power to rotate through gear transmission, there is generally no overload protection function. Once overloaded, it is easy to cause failure forms such as gear tooth wear and breakage, and even damage the entire transmission system.

[0040] By providing the pull rod 41 as an intermediate carrier, the force on the guide portion 111 can be reduced compared to directly providing the driving member 44 on the turntable 42. By providing the pull rod 41, the turntable 42 and the driving member 44 for transmission, the opening and closing movement of the massage head 3 is more stable.

[0041] like Figure 1 and Figure 2 As shown, the shell 2 includes an upper shell 22 and a lower shell 21 that are detachably fixedly connected, and can be fixed by screws, so that it is convenient to repair the driving mechanism 5 when it is damaged. The bottom surface of the lower shell 21 is horizontally provided with a transverse groove 211 along a direction perpendicular to the sliding direction of the massage movement on the frame 1. The driving member 44 is slidably arranged in the transverse groove 211. Through the transverse groove 211 arranged in this way, it can be ensured that under the same movement stroke of the massage head 3, the length of the transverse groove 211 is minimized, reducing the groove damage area of ​​the lower shell 21. At the same time, through such an arrangement, the contact wear stroke between the driving member 44 and the transverse groove 211 can be minimized when sliding along the guide portion 111.

[0042] like Figure 3 As shown, a fixed shaft 45 is detachably fixed on the rotating disk 42, and the fixed shaft 45 passes through the pull rod 41 and the bottom of the lower shell 21, and one end of the pull rod 41 is hinged to the fixed shaft 45;

[0043] By such an arrangement, it is ensured that the driving member 44 slides along the guide portion 111. The driving member 44 moves in the transverse groove 211, which can drive the pull rod 41 to move, thereby ensuring that the pull rod 41 can drive the turntable 42 to rotate. By setting a fixed shaft 45 that passes through the bottom of the lower shell 21, the rotation of the turntable 42 is more stable.

[0044] like Figure 3 and Figure 4 As shown, the bottom surface of the lower shell 21 is provided with a first arc-shaped guide groove 212 and a second arc-shaped guide groove 213, the support rod 43 is slidably disposed in the first arc-shaped guide groove 212, and the fixed shaft 45 is slidably disposed in the second arc-shaped guide groove 213, where the fixed shaft 45 can be set as a shaft rod;

[0045] By setting the support rod 43 to move in the first arc-shaped guide groove 212 and the fixed shaft 45 to move in the second arc-shaped guide groove 213, a centering and guiding function is further provided, so that the rotation of the turntable 42 and the movement of the pull rod 41 are more stable;

[0046] like Figure 3 As shown, a sleeve 46 is fixed on the outer surface of the driving member 44. Since the driving member 44 not only slides in the second arc-shaped guide groove 213, but also slides on the guide portion 111, its wear will be relatively more serious. Therefore, the setting of the sleeve 46 can provide good protection for the driving member 44 and extend its service life.

[0047] like Figure 2 and Figure 3 As shown, a kneading gear 57 is fixedly installed on the outer surface of the support rod 43, and a driving mechanism 5 for driving the kneading gear 57 to rotate is provided in the housing 2. The kneading gear 57 is driven to rotate by the driving mechanism 5, thereby driving the support rod 43 to rotate, and finally the massage head 3 performs a rotation massage work;

[0048] Specifically, the driving mechanism 5 includes a dual-axis motor 51 and two sets of first transmission gear sets. The two output ends of the dual-axis motor 51 are fixedly mounted with a worm 52. Each first transmission gear set includes a worm wheel 53, a first gear 54, a second gear 55 and a third gear 56. The worm wheel 53 and the first gear 54 are coaxially fixed and rotatably arranged on the lower shell 21. The second gear 55 and the third gear 56 are coaxially fixed and rotatably arranged on the lower shell 21. The worm wheel 53 is meshed with the worm 52, the first gear 54 is meshed with the second gear 55, and the third gear 56 is meshed with the kneading gear 57.

[0049] By driving the dual-axis motor 51 to drive the two worms 52 to rotate, the worm 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the first gear 54 to rotate, the first gear 54 drives the second gear 55 to rotate, the third gear 56 follows the second gear 55 to rotate, the third gear 56 drives the kneading gear 57 to rotate, thereby driving the support rod 43 to rotate, and finally performing the rotation massage work of the massage head 3;

[0050] By setting the size of the worm gear 53 to be larger than the size of the first gear 54, the size of the first gear 54 to be smaller than the size of the second gear 55, the size of the second gear 55 to be larger than the size of the third gear 56, and the size of the third gear 56 to be smaller than the size of the kneading gear 57, the multi-stage transmission set in this way has a large transmission ratio and a stronger output torque, thereby preventing the massage head 3 from being restricted in rotation when the human body is too heavy on the massage head 3, and ensuring that the massage head 3 can rotate normally when people lean on the massage head 3.

[0051] like Figure 3 As shown, the center points of the worm gear 53, the third gear 56 and the kneading gear 57 are arranged in a triangle. Through such an arrangement, the structural position arrangement of each gear can be made more compact. The pull rod 41 is arc-shaped and its arc-shaped opening faces the second gear 55. This can avoid contact and collision with the center axes of the second gear 55 and the third gear 56 when the pull rod 41 moves.

[0052] like Figure 1-Figure 3 As shown, the traveling movement also includes a traveling gear 7 rotatably disposed on the lower shell 21 and protruding from the housing 2, a rack 12 meshing with the traveling gear 7 is disposed on the frame 1, a second transmission gear set 6 is disposed in the housing 2, the second transmission gear set 6 includes a fourth gear 61, a fifth gear 62 and a sixth gear 63, the fourth gear 61 and the fifth gear 62 are coaxially fixed and rotatably disposed on the lower shell 21, the sixth gear 63 and the traveling gear 7 are coaxially fixed and rotatably disposed on the lower shell 21, the first gear 54 meshes with the fourth gear 61, and the fifth gear 62 meshes with the sixth gear 63;

[0053] When the dual-axis motor 51 is started, the dual-axis motor 51 drives the worm 52 to rotate, the worm 52 drives the worm wheel 53 to rotate, the worm wheel 53 drives the first gear 54 to rotate, the first gear 54 drives the second gear 55 to rotate and drives the fourth gear 61 to rotate, the fourth gear 61 drives the fifth gear 62 to rotate, the fifth gear 62 drives the sixth gear 63 to rotate, and the sixth gear 63 drives the travel gear 7 to rotate synchronously, so that the travel gear 7 moves along the rack 12, thereby completing the movement on the frame 1.

[0054] Similarly, by setting the size of the first gear 54 to be smaller than the size of the fourth gear 61, the size of the fourth gear 61 to be larger than the size of the fifth gear 62, the size of the fifth gear 62 to be smaller than the size of the sixth gear 63, and the size of the sixth gear 63 to be larger than the size of the traveling gear 7, the multi-stage transmission set in this way has a large transmission ratio and a stronger output torque, thereby preventing the massage movement from being restricted on the frame 1 when the human body is too heavy on the massage head 3.

[0055] like Figure 1As shown, the guide portion 111 is a guide groove or a guide rail, which is symmetrically arranged on the back plate 11. Here, the guide portion 111 is taken as a guide groove for example. It is opened on the back plate 11. On the one hand, it can reduce the overall weight, and on the other hand, it is convenient to avoid the additional setting of a guide rail, so that the cost is relatively lower.

[0056] like Figure 1 As shown, the frame 1 includes a back plate 11, a vertical beam 13 and a horizontal beam 14 which are detachably fixedly connected, and a guide portion 111 is provided on the back plate 11;

[0057] Specifically, the back plate 11, the vertical beam 13 and the horizontal beam 14 are detachably fixedly connected by screws, so that the back plate 11 with the guide part 111 having different trajectories can be easily replaced to meet the needs of different groups of people for different movement strokes of the massage head 3.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
