Description

Technical Field

[0001] The invention relates to the technical field of massage movement, in particular to a massage movement with a compact structure. Background Art

[0002] Nowadays, people are under increasing pressure in life and their bodies are becoming more and more tired, so they need to use some auxiliary tools to eliminate fatigue. With the widespread application of mechanization and automation, various massagers that simulate artificial massage have entered thousands of households, and massage devices have come into being.

[0003] The existing authorization announcement number of "A massage head device" is CN206342658U. It drives the mounting frame to move up and down by using a turbine shaft, a worm gear and a transmission screw. It not only has a simple and reasonable structure and low manufacturing cost, but also has a long service life and generates less noise during operation, which is beneficial to improving the therapeutic effect.

[0004] There is also an "up and down motion adjustment device for warm therapy device" with authorization announcement number CN102462617B. As the moxibustion device moves in a circular arc and rises, it can simultaneously obtain pressing effect and pushing effect. Therefore, it can not only improve the massage effect obtained by the moxibustion device, but also improve the warm therapy effect.

[0005] For the first type, "a massage head device", since the transmission screw is arranged perpendicular to the top surface of the walking frame and protrudes from the walking frame, the volume of the entire massage head device is relatively large; for the second type, "an up and down motion adjustment device for a warm therapy device", although an arc-shaped gear component is provided, the volume of the device is reduced to a certain extent compared with the first type of vertically arranged transmission screw, but the overall structure volume is still relatively large, and the device has high requirements on the processing and installation accuracy of the rack, so the manufacturing cost is also high. At the same time, the massage head needs to be frequently lifted and lowered during use, so the wear on the gear and rack is large, resulting in a relatively short service life. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a compact and small massage movement to solve the problem that the existing massage movement has a large volume when the massage head is ejected and massaged by a transmission screw or an arc-shaped gear component arranged perpendicular to the top surface of the walking frame.

DETAILED DESCRIPTION

[0028] 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.

[0029] like Figure 1-Figure 3 As shown, the present invention provides a compact massage movement, including a housing 1 and at least one first massage head 31 located above the housing 1, and also includes: a rotating shaft 5, an adjustment mechanism 4 and a support member 2;

[0030] The rotating shaft 5 is rotatably disposed in the housing 1;

[0031] The adjustment mechanism 4 includes a first driving assembly and a sliding member 45 which are horizontally arranged inside the housing 1. The first driving assembly drives the sliding member 45 to move horizontally inside the housing 1.

[0032] The support member 2 is fixedly connected to the rotating shaft 5, one end of the support member 2 passes through the top surface of the housing 1 and is provided with a first massage head 31, and the other end of the support member 2 is movably connected to the sliding member 45;

[0033] When the first driving component is adjusted to drive the sliding member 45 to move horizontally in the shell 1, the sliding member 45 drives the supporting member 2 and the rotating shaft 5 to rotate around the center line of the rotating shaft 5, so that the first massage head 31 performs an arc-shaped ejection movement. By horizontally arranging the first driving component and the sliding member 45 in the shell 1, the volume of the entire massage movement is greatly reduced compared with the existing driving component (transmission screw 44) arranged perpendicular to the top surface of the walking frame and the arc-shaped gear component, making the structure of the entire massage movement more compact.

[0034] like Figure 2 As shown, the adjustment mechanism 4 also includes a connecting rod 46, and the first driving assembly includes a first motor 41, a first worm 42, a first worm wheel 43 and a screw 44. The first motor 41 is fixedly installed horizontally in the housing 1, and the output end of the first motor 41 is fixedly connected to the first worm 42. A screw 44 is provided for horizontal rotation in the housing 1, and one end of the screw 44 is detachably fixedly connected to the first worm wheel 43. The first worm wheel 43 and the first worm 42 are meshed. The outer surface of the screw 44 is spirally screwed with a sliding member 45, and both ends of the sliding member 45 are hinged with connecting rods 46, and one end of the connecting rod 46 is hinged to the other end of the support member 2;

[0035] The specific working principle of the first massage head 31 rotating in an arc around the center line of the rotating shaft 5 is as follows: the first motor 41 is started by switching forward and reverse at a fixed time, so that the first motor 41 drives the first worm 42 to switch forward and reverse, thereby the first worm wheel 43 switches forward and reverse, and the first worm wheel 43 drives the screw rod 44 to switch forward and reverse, thereby driving the sliding member 45 to reciprocate on the screw rod 44. Since the sliding member 45 is hinged with the connecting rod 46, and one end of the connecting rod 46 is hinged with the other end of the supporting member 2, the sliding member 45 will drive the connecting rod 46 to move horizontally. The end of the connecting rod 46 hinged to the support member 2 swings in an arc shape, thereby driving the support member 2 and the rotating shaft 5 to reciprocate around the center line of the rotating shaft 5, that is, the first massage head 31 follows the movement of the support member 2 to complete the arc-shaped ejection massage work. The transmission between the screw rod 44 and the sliding member 45 is relative to the transmission between the existing arc-shaped gear component and the rack, which avoids the high processing and installation precision requirements of the arc-shaped gear component and the rack, saves manufacturing costs, and at the same time prevents the gear and rack from being worn out during use, resulting in a relatively short service life.

[0036] like Figure 1 and Figure 2As shown, the housing 1 includes a first housing 11, a second housing 12 and a third housing 13, one side of the second housing 12 is provided with a notch adapted to the third housing 13, the first housing 11 and the second housing 12 are detachably fixedly connected (here they can be fixed by screws), the third housing 13 and the second housing 12 are detachably fixedly connected (here they can be fixed by screws), the second housing 12 is detachably fixedly connected with a circuit board 6, the circuit board 6 is located between the second housing 12 and the third housing 13, and the first drive assembly is located between the first housing 11 and the second housing 12;

[0037] By setting the shell 1 as three parts, namely the first shell 11, the second shell 12 and the third shell 13, the circuit board 6 is fixed between the second shell 12 and the third shell 13, and the first drive assembly is located between the first shell 11 and the second shell 12. Therefore, when the circuit board 6 is damaged and needs to be repaired or replaced, the third shell 13 can be removed separately, so that the circuit board 6 can be removed and replaced separately, thereby avoiding the situation in which the traditional massage device uniformly places the circuit board 6 and the driving structures such as the motor between the first shell 11 and the second shell 12. When the circuit board 6 needs to be repaired, the driving structures such as the motor will be exposed to the air, so that dust and impurities in the air will fall onto the driving structures such as the motor, which may affect the heat dissipation of the motor, and may increase the transmission resistance of the driving structure (such as the first worm 42, the first worm wheel 43 and the lead screw 44 here), reduce the transmission efficiency, reduce the transmission accuracy, and even cause malfunctions.

[0038] like Figure 3 and Figure 4 As shown, two first bases 111 are fixedly installed on the bottom surface of the inner wall of the first housing 11, and a fixing seat 112 is detachably fixedly installed on the first base 111, and the screw rod 44 is rotatably inserted between the two fixing seats 112, and the connecting rod 46 and the sliding member 45 are both spaced apart from the bottom surface of the inner wall of the first housing 11;

[0039] By setting the first base 111 and the fixing base 112, the screw rod 44 can be disassembled and assembled, so that when the screw rod 44 is damaged, it is convenient to quickly disassemble and replace it. In addition, after assembling the fixing base 112, the screw rod 44 is in a suspended state, and the connecting rod 46 and the sliding member 45 have a gap with the bottom surface of the inner wall of the first shell 11, ensuring that when the first motor 41 is started, the connecting rod 46 will not contact or collide with the inner wall of the first shell 11 during movement.

[0040] like Figure 2 and Figure 3As shown, the support member 2 is a U-shaped plate, and the U-shaped plate includes two vertical parts 21 and a horizontal part 22. By such a configuration, the vertical part 21 can fix the rotating shaft 5, and the horizontal part 22 can fix the first supporting rod 3. The horizontal part 22 is located outside the shell 1 and is detachably fixedly connected to the first supporting rod 3 (here it can be set to be fixed by screws), and both ends of the first supporting rod 3 can be detachably fixedly connected to the first massage head 31 (the specific detachable and fixed connection method of the first massage head 31 and the second massage head 32 below can refer to the fixed component of a warm massager with an up and down adjustment device with the authorization announcement number CN221655068U), there are two rotating shafts 5, and the two rotating shafts 5 are symmetrically fixed on both sides of the U-shaped plate;

[0041] By providing two rotating shafts 5 and symmetrically fixing them on both sides of the U-shaped plate, on the one hand, it can save material costs and reduce the weight of the entire massage movement. On the other hand, the volume of the entire massage movement can be further reduced. Because when a rotating shaft 5 is provided to be fixed through the U-shaped plate, it is necessary to increase the height of the second base 113 or lengthen the distance between the rotating shaft 5 and the fixed seat 112 to ensure that there is no contact between the rotating shaft 5 and the fixed seat 112, which will increase the overall volume of the massage movement.

[0042] like Figure 2-Figure 4 As shown, two second bases 113 are fixedly installed on the bottom surface of the inner wall of the first shell 11, and a first semicircular groove 1131 is opened on the top of the second base 113, and a second semicircular groove (not shown in the figure) is provided on the inner wall of the second shell 12. When the second shell 12 is fixed to the first shell 11, the size of the first semicircular groove 1131 and the second semicircular groove is adapted to the cross-sectional size of the rotating shaft 5, and the two rotating shafts 5 are away from each other and abut against the inner wall of the second shell 12 at both ends. The height of the second base 113 is higher than that of the first base 111, ensuring that there is enough space to install the fixing base 112 on the first base 111 without increasing the overall height and volume of the massage movement. After the fixing base 112 is installed on the first base 111, the height position of the top surface of the fixing base 112 is not higher than the height position of the top of the rotating shaft 5, avoiding an additional increase in the overall height of the massage movement.

[0043] By means of the first semicircular groove 1131 and the second semicircular groove arranged in this way, when the second shell 12 is assembled with the first shell 11, the rotating shaft 5 can be well limited so that it can rotate within the space enclosed by the first semicircular groove 1131 and the second semicircular groove. At the same time, when the rotating shaft 5 is severely worn and needs to be replaced, it is only necessary to disassemble the second shell 12, so that the rotating shaft 5 can be quickly taken out and replaced.

[0044] like Figure 2 and Figure 3As shown, the second housing 12 is provided with two movable grooves 121 not less than the thickness of the vertical portion 21 and two movable holes 122 not less than the plane size of the horizontal portion 22. The movable holes 122 are connected to the movable grooves 121, and a detachable fixed sealing plate 123 is provided in the movable holes 122;

[0045] By setting the movable groove 121, it is ensured that when the first driving component drives the sliding member 45 to move horizontally in the shell 1, the vertical portion 21 and the rotating shaft 5 can rotate normally in the movable groove 121 around the center line of the rotating shaft 5. Through the opened movable hole 122, when the fixed seat 112 is fixed on the first base 111, the rotating shaft 5 is located in the first semicircular groove 1131, and the positions of the screw rod 44, the sliding member 45, the connecting rod 46 and the support member 2 are relatively fixed, when assembling the second shell 12, the horizontal portion 22 of the support member 2 can pass through the movable hole 122, thereby ensuring the normal assembly of the second shell 12, and by setting the sealing plate 123, the movable hole 122 can be closed after the second shell 12 is assembled, thereby preventing foreign debris from entering the first shell 11 and the second shell 12 through the movable hole 122 to affect the normal operation of the internal first driving component, and after the sealing plate 123 is assembled, the first support rod 3 and the first massage head 31 are assembled.

[0046] like Figure 3-Figure 5 As shown, the third base 114 is also fixedly installed on the bottom surface of the inner wall of the first housing 11, and the shaft sleeve 10 is fixedly installed on the third base 114. Both ends of the screw rod 44 are provided with plug-in parts, and the outer surface of one plug-in part is rotatably connected to the shaft sleeve 10. The first worm gear 43 is detachably fixed to the plug-in part, and the first worm gear 43 is located between the shaft sleeve 10 and the fixed seat 112;

[0047] By setting the shaft sleeve 10, auxiliary centering and further supporting effects are played on the screw rod 44, thereby avoiding foreign debris between the fixed seat 112 and the first base 111 when installing the fixed seat 112, and making the height position of the fixed seat 112 fixed on the first base 111 slightly higher, thereby avoiding the situation that the first worm wheel 43 and the first worm 42 cannot engage after the position of the screw rod 44 is fixed.

[0048] like Figure 5 As shown, a positioning groove matching the size of the plug-in portion is provided on the opposite side of the two fixing seats 112, a first through hole 431 matching the plug-in portion is provided through the first worm gear 43, a second through hole 441 is provided on the plug-in portion along a direction perpendicular to the screw rod 44, a limiting rod 442 is movably inserted in the second through hole 441, a limiting groove 432 matching the size of the limiting rod 442 is provided on one side of the first worm gear 43, the limiting groove 432 is communicated with the first through hole 431, and a wear-resistant ring 14 is provided between the first worm gear 43 and the fixing seat 112;

[0049] The specific assembly principle of the screw rod 44 and the first worm gear 43 here is: insert the plug-in portion at one end of the screw rod 44 into the positioning groove on a fixing seat 112, then insert the limiting rod 442 into the second through hole 441, and then sleeve the first worm gear 43 on the outer surface of the plug-in portion so that the limiting rod 442 enters the limiting groove 432, thereby completing the preliminary positioning of the first worm gear 43, and finally insert the plug-in portion at the other end into the positioning groove on another fixing seat 112 after the wear-resistant ring 14 is inserted. At this time, the two sides of the wear-resistant ring 14 are respectively connected to the first worm gear 43 and the fixing seat 112 fits together, and the first worm gear 43 is limited and fixed by the limiting rod 442 and the wear-resistant ring 14, and then the two fixing seats 112 assembled with the screw rod 44 and the first worm gear 43 are fixed to the first base 111 by screws, that is, the screw rod 44 is horizontally fixed to the first shell 11. Through such an arrangement, when the first worm gear 43 or the screw rod 44 is worn and damaged, it can be disassembled and replaced separately, avoiding the situation where the first worm gear 43 and the screw rod 44 are an inseparable whole, and when a certain component is damaged, the whole needs to be replaced, resulting in waste of materials.

[0050] like Figure 3 and Figure 4 As shown, the massage movement also includes a driving mechanism 9 arranged between the first housing 11 and the second housing 12, a driving gear 7 and a driven gear 8 are rotatably arranged on the first housing 11, and the driving gear 7 and the driven gear 8 are partially located outside the first housing 11, and the driving gear 7 and the driven gear 8 are arranged here on both sides of the first housing 11, and the driving mechanism 9 includes a second driving assembly and a reduction assembly, the second driving assembly includes a second motor 91 and a second worm 92, and the reduction assembly includes a second worm wheel 93 and a first gear 94 that rotate concentrically and a second gear 95 and a third gear 96 that rotate concentrically, which are arranged on the first housing 11, the size of the second worm wheel 93 is larger than the size of the first gear 94 and meshes with the second worm 92, the size of the first gear 94 is smaller than the size of the second gear 95 and meshes with it, and the size of the third gear 96 is smaller than the size of the second gear 95 and the driving gear 7 and meshes with the driving gear 7;

[0051] When the massage movement is in use, it is placed on a long base with a long groove, in which a rack matched with the driving gear 7 and the driven gear 8 is provided (this is the existing structure). By setting the driving walking mechanism 9, the massage movement can be moved in the long groove of the long base along the rack, so that when a person lies on the long base, the person's back can be fully massaged. Here, the second worm gear 93 and the first gear 94 are arranged to rotate concentrically, and the second gear 95 and the third gear 96 are arranged to rotate concentrically. The two sets of gear structures are used to reduce speed, thereby reducing the rotation speed of the driving gear 7, that is, reducing the speed of the massage movement moving along the rack in the long groove of the long base, so that people can have a more comfortable massage.

[0052] like Figure 1 and Figure 2 As shown, the second support rod can be detachably fixedly installed on the top surface of the second housing 12 (here it can be fixed by screws), and both ends of the second support rod can be detachably fixedly connected to the second massage head 32;

[0053] When the first driving component drives the sliding member 45 to move horizontally in the shell 1, the height position of the second massage head 32 is not higher than the height position of the first massage head 31. When the first driving component drives the sliding member 45 to move horizontally in the shell 1 by adjusting the first driving component to make the first massage head 31 move to the same height as the second massage head 32, the first massage head 31 and the second massage head 32 can perform massage together. When the first driving component drives the sliding member 45 to move horizontally in the shell 1 by adjusting the first driving component to make the height position of the first massage head 31 gradually higher than the height position of the second massage head 32, the first massage head 31 plays a role of ejection massage.

[0054] 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.
