Description

Technical Field

[0001] This utility model relates to the field of massage mechanism, specifically a multi-purpose massage mechanism with a linkage-driven 3D mechanism. Background Technology

[0002] Existing massage mechanisms are typically fixedly mounted on a massage frame. The massage mechanism moves vertically within the frame via guide rails and its own traveling mechanism. This design allows the massage unit to shift vertically, thus covering different massage areas.

[0003] However, human muscle groups are not flat structures; for example, the shoulders, back, sides of the spine, and waist exhibit continuous curved changes. Traditional massage mechanisms can only move vertically during operation, and the front-to-back position of the massage mechanism relative to the frame remains fixed. This prevents them from actively conforming to the body, resulting in insufficient contact and poor fit in some massage areas, thus affecting the overall massage experience. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose massage mechanism with a linkage-driven 3D mechanism. It has stable transmission, can actively conform to the massage area and perform kneading, tapping and kneading-tapping massage, and has good massage comfort.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A linkage-driven 3D multi-purpose massage mechanism is mounted on a massage frame and includes a base plate and a massage mechanism; the massage mechanism is mounted on the base plate and is used to perform massage.

[0007] The left and right sides of the base plate are respectively connected to swing arms via a first pivot shaft, and a guide rod is connected between the two swing arms. The guide rod is located on the rear side of the base plate.

[0008] The swing arm is also provided with a fulcrum part that cooperates with the massage frame. A lifting mechanism is provided between the guide rod and the base plate to drive the base plate to swing around the first pivot axis, thereby driving the massage mechanism to extend forward or return to its original position relative to the massage frame.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. Through the cooperation of the swing arm, fulcrum and extension mechanism, the base plate can swing around the first pivot axis, thereby driving the massage mechanism to extend forward or return to its original position, so that the massage mechanism can better fit the user's massage area and improve the massage comfort.

[0011] 2. By combining the kneading and tapping units, the massage arms can perform kneading and tapping actions simultaneously, providing a variety of massage options and enhancing massage comfort. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0025] like Figure 1-11 The image shown is a schematic diagram of an embodiment of a linkage-driven 3D multi-purpose massage mechanism provided by this utility model:

[0026] A linkage-driven 3D multi-purpose massage mechanism is mounted on a massage frame and includes a base plate 1 and a massage mechanism; the massage mechanism is mounted on the base plate 1 and is used to perform massage.

[0027] The left and right sides of the base plate 1 are respectively connected to swing arms 3 via the first pivot shaft 2, and a guide rod 4 is connected between the two swing arms 3. The guide rod 4 is located on the rear side of the base plate 1.

[0028] The swing arm 3 is also provided with a fulcrum 5 that cooperates with the massage frame. A lifting mechanism 6 is provided between the guide rod 4 and the base plate 1 to drive the base plate 1 to swing around the first pivot shaft 2, thereby driving the massage mechanism to extend forward or return to its original position relative to the massage frame.

[0029] The extension mechanism 6 includes an extension drive assembly and an extension connecting rod 61. The extension drive assembly is installed on the rear side of the base plate 1, and the extension connecting rod 61 is connected between the extension drive assembly and the guide rod 4.

[0030] The top extension drive assembly is used to drive the top extension link 61 to move, so as to adjust the relative distance between the guide rod 4 and the base plate 1, thereby causing the base plate 1 to swing around the first pivot axis 2.

[0031] The extension drive assembly includes an extension motor 62, a lead screw slide, and a guide sleeve 64;

[0032] In this embodiment, the top extension motor 62 is fixed to the rear side of the base plate 1, and a first transmission component 621 is fixedly connected to its output end; the lead screw slide is arranged laterally on the rear side of the base plate 1, and a second transmission component 632 is installed on its lead screw part 631. The first transmission component 621 and the second transmission component 632 are connected in a transmission manner to drive the lead screw part 631 to rotate.

[0033] In this embodiment, the first transmission component 621 is a transmission worm, and the second transmission component 632 is a transmission worm wheel. The first transmission component 621 and the second transmission component 632 are meshing transmissions. In some embodiments, the first transmission component 621 may also be a spur gear, bevel gear, etc., and the second transmission component 632 may be a spur gear, bevel gear, etc., that matches the first transmission component 621.

[0034] The guide sleeve 64 is slidably connected to the outside of the guide rod 4. One end of the top extension rod 61 is pivotally connected to the guide sleeve 64 via the second pivot shaft 65, and the other end is pivotally connected to the sliding part 633 of the lead screw slide via the third pivot shaft 66. Both the second pivot shaft 65 and the third pivot shaft 66 are vertically arranged. It should be specifically noted that in this embodiment, the lead screw part 631 rotates and drives the sliding part 633. At this time, the sliding part 633 itself does not rotate, but only moves along the axial direction of the lead screw part 631, and pushes the top extension rod 61 to swing, thereby adjusting the relative distance between the guide rod 4 and the base plate 1, and thus driving the base plate 1 to swing around the first pivot shaft 2.

[0035] In some embodiments, the lead screw slide is located between the guide rod 4 and the first pivot shaft 2. The lead screw part 631 rotates and drives the sliding part 633. At this time, the sliding part 633 itself rotates. The lower end of the extension connecting rod 61 is fixed on the sliding part 633, while the upper end is fixed on the guide sleeve 64.

[0036] When the lead screw 631 rotates and drives the sliding part 633 to rotate, the upper end of the extension connecting rod 61 drives the guide rod 4 to swing around the first pivot axis 2, thereby adjusting the relative distance between the guide rod 4 and the base plate 1, and thus driving the base plate 1 to swing around the first pivot axis 2.

[0037] The fulcrum 5 includes a passive walking wheel 51 that slides vertically with the massage frame and a fourth pivot shaft 52 that extends to the left and right. The passive walking wheel 51 is pivotally connected to the swing arm 3 through the fourth pivot shaft 52.

[0038] The massage mechanism includes a kneading unit 7 and a tapping unit 8. The tapping unit 8 is connected to the kneading unit 7 and is used to drive the kneading unit 7 to perform tapping.

[0039] The kneading unit 7 includes a kneading motor 71, a kneading shaft 72 arranged horizontally, and two transmission arms 73.

[0040] The kneading motor 71 is mounted on the base plate 1, and its output end is fixedly connected to the fifth transmission component 711. The kneading shaft 72 is rotatably mounted on the base plate 1, and the kneading shaft 72 is equipped with the sixth transmission component 721 in the middle. The fifth transmission component 711 is connected to the sixth transmission component 721 in a transmission connection.

[0041] Both ends of the kneading shaft 72 are obliquely provided with stepped shafts 74. The middle sections of the two transmission arms 73 are respectively mounted on the corresponding stepped shafts 74 on both sides through bearings. The front end of the transmission arm 73 is connected to a massage arm 75. The kneading motor 71 drives the kneading shaft 72 to rotate and drives the transmission arm 73 and the massage arm 75 to reciprocate, thereby realizing kneading.

[0042] The massage arm 75 includes an arc-shaped frame 751 and two massage rollers 752. The two massage rollers 752 are respectively installed at both ends of the arc-shaped frame 751, and the middle part of the arc-shaped frame 751 is hinged to the front end of the transmission arm 73.

[0043] The striking unit 8 includes a striking motor 81, a striking rotating shaft 82, a driving pulley 83, a driven pulley 84, and two striking transmission components 85;

[0044] The striking motor 81 is mounted on the base plate 1, and the driving pulley 83 is fixed on the output shaft of the striking motor 81; the striking rotating shaft 82 is coaxially connected to the driven pulley 84 and rotatably mounted on the base plate 1, and the driving pulley 83 and the driven pulley 84 are connected by belt drive.

[0045] Both ends of the striking rotating shaft 82 are provided with striking eccentric shafts 86, and two striking transmission components 85 are respectively installed on the striking eccentric shafts 86 on both sides and are hinged to the bottom end of the transmission arm 73 on the corresponding side.

[0046] The striking motor 81 drives the striking rotating shaft 82 and the striking eccentric shaft 86 to rotate, and drives the striking transmission assembly 85 to reciprocate, thereby pushing the transmission arm 73 to perform striking.

[0047] The striking transmission assembly 85 includes a striking bearing 851 and a universal ball joint connecting rod 852. The striking bearing 851 is mounted on the striking eccentric shaft 86. The ball joint end of the universal ball joint connecting rod 852 is hinged to the bottom end of the transmission arm 73, and its other end is hinged to the outer side of the striking bearing 851.

[0048] An clearance opening 10 is provided on the base plate 1, and the front end of the transmission arm 73 is connected to the massage arm 75 through the clearance opening 10.

[0049] The aforementioned linkage-driven 3D multi-purpose massage mechanism also includes a walking mechanism 9 for driving the vertical displacement of the base plate 1. The walking mechanism 9 includes a walking motor 91 and a main rotating shaft 92 rotatably connected to the base plate 1.

[0050] The output end of the walking motor 91 is fixedly connected to a third transmission component 911, and a fourth transmission component 921 is fixedly provided on the main rotating shaft 92. The third transmission component 911 and the fourth transmission component 921 are connected in a transmission manner.

[0051] In this embodiment, the third transmission component 911 is a transmission worm gear, and the fourth transmission component 921 is a transmission worm wheel. The third transmission component 911 and the fourth transmission component 921 are meshing transmissions. In some embodiments, the third transmission component 911 may also be a spur gear, bevel gear, etc., and the fourth transmission component 921 may be a spur gear, bevel gear, etc., that matches the third transmission component 911.

[0052] Both ends of the main rotating shaft 92 are fixed with active walking wheels 922 and walking teeth 923. The active walking wheels 922, walking teeth 923 and the main rotating shaft 92 are coaxially arranged. The massage frame is provided with a rack that cooperates with the walking teeth 923 and a guide rail that cooperates with the active walking wheels 922.

[0053] The working principle of this utility model is roughly as follows:

[0054] The massage mechanism of this utility model has the functions of kneading, tapping, kneading and tapping, as well as kneading, tapping, kneading and tapping under vertical displacement and forward and backward extension conditions. Through the cooperation of the swing arm 3, the fulcrum part 5 and the extension mechanism 6, the massage mechanism can realize the forward and backward posture change relative to the massage frame, so as to improve the fit between the massage mechanism and the user.

[0055] When the output of the extension motor 62 rotates in the forward direction, the first transmission member 621 drives the lead screw part 631 of the lead screw slide to rotate. The lead screw part 631 drives the sliding part 633 to move linearly along its axial direction. In this embodiment, the movement of the sliding part 633 drives the extension connecting rod 61 to swing through the second pivot shaft 65 and the third pivot shaft 66, thereby causing the guide sleeve 64 to slide on the guide rod 4, thus changing the relative distance between the guide rod 4 and the base plate 1. The change in the relative distance between the guide rod 4 and the base plate 1 will cause the base plate 1 to move around the first pivot shaft 2. During this process, since the fulcrum part 5 on the swing arm 3 abuts against the massage frame, it provides a reaction force support for the swing of the base plate 1, realizing the forward extension of the massage mechanism. When the output of the extension motor 62 rotates in the reverse direction, the lead screw part 631 rotates and resets the sliding part 633, the extension connecting rod 61, and the base plate 1.

[0056] When the kneading motor 71 starts, the fifth transmission component 711 drives the sixth transmission component 721 in the middle of the kneading shaft 72 to rotate. The kneading shaft 72 rotates accordingly and drives the stepped shafts 74 at both ends to make eccentric movements. The transmission arm 73 installed on the stepped shaft 74 swings back and forth, so that the massage arm 75 at the front end of the transmission arm 73 kneads the user.

[0057] When the tapping motor 81 is started, it drives the tapping rotating shaft 82 to rotate via the driving pulley 83 and the driven pulley 84. The tapping eccentric shafts 86 at both ends of the tapping rotating shaft 82 oscillate eccentrically, thereby driving the tapping transmission assembly 85 to reciprocate. Since the tapping transmission assembly 85 is hinged to the transmission arm 73, the movement of the tapping transmission assembly 85 drives the transmission arm 73 to swing together, causing the massage arm 75 to tap the human body.

[0058] When the kneading motor 71 and the striking motor 81 start simultaneously, the transmission arm 73 adds a striking action on top of the kneading action, thereby achieving the joint operation of kneading and striking.

[0059] When the walking motor 91 starts, the third transmission component 911 at the output end of the walking motor 91 drives the fourth transmission component 921 and the main rotating shaft 92 to rotate. The active walking wheels 922 at both ends of the main rotating shaft 92 cooperate with the guide rails on the massage frame. At the same time, the walking gear 923 meshes with the rack, causing the base plate 1 to move vertically along the frame. While the massage mechanism is moving vertically, the extension mechanism 6 can be activated as needed, so that the massage mechanism can further perform forward extension, backward reset, kneading, tapping or kneading and tapping on the basis of vertical movement, in order to adapt to different massage parts of the human body and improve the massage fit and comfort.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
