Description

Technical Field

[0001] This utility model relates to the field of massage mechanism technology, and in particular to a compact and small massage mechanism. Background Technology

[0002] Nowadays, people face increasing life pressures and become more and more physically exhausted. As a result, they need to use some auxiliary tools to relieve fatigue. With the widespread application of mechanization and automation, various massagers that simulate manual massage have entered thousands of households, and massage devices have thus emerged.

[0003] The existing patent announcement number CN206342658U, "A Massage Head Device", uses a combination of a turbine shaft, a worm gear, and a transmission screw to drive the lifting motion of the mounting frame. This 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 physiotherapy effect.

[0004] Another example is the "Up-and-Down Movement Adjustment Device for Thermotherapy Instrument" with authorization announcement number CN102462617B. As the moxibustion device moves in an arc and rises, it can simultaneously obtain both pressing and pushing effects. Therefore, it can not only improve the massage effect obtained by the moxibustion device, but also improve the thermotherapy effect.

[0005] For the first type, "a massage head device," the entire massage head device is relatively large because the transmission screw is set perpendicular to the top surface of the walking frame and protrudes from the walking frame. For the second type, "a vertical movement adjustment device for a thermotherapy instrument," although an arc-shaped gear component is set, which reduces the size of the device to some extent compared to the first type with a vertically set transmission screw, the overall structural volume is still relatively large. Moreover, this device has high requirements for the processing and installation precision of the rack, so the manufacturing cost is also high. At the same time, the massage head needs to be frequently raised and lowered during use, so the wear on the gears and rack is greater, resulting in a relatively short service life. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a compact and small massage mechanism to solve the problem that the existing massage mechanism is large in size when the massage head is pushed out for massage by a transmission screw or arc-shaped gear component set perpendicular to the top surface of the walking frame.

[0012] Preferably, the housing includes a first outer shell, a second outer shell, and a third outer shell. One side of the second outer shell is provided with a notch adapted to the third outer shell. The first outer shell and the second outer shell are detachably and fixedly connected. The third outer shell and the second outer shell are detachably and fixedly connected. A circuit board is detachably and fixedly connected to the second outer shell. The circuit board is located between the second outer shell and the third outer shell. The first driving component is located between the first outer shell and the second outer shell.

[0013] Preferably, two first bases are fixedly installed on the bottom surface of the inner wall of the first housing, and fixed seats are detachably and fixedly installed on the first bases. The lead screw is rotatably inserted between the two fixed seats, and the connecting rod and the sliding member have gaps with the bottom surface of the inner wall of the first housing.

[0014] Preferably, the support member is a U-shaped plate, which includes two vertical parts and one horizontal part. The horizontal part is located outside the housing and is detachably and fixedly connected to a first support rod. Both ends of the first support rod are detachably and fixedly connected to a first massage head. There are two rotating shafts, which are symmetrically fixed on both sides of the U-shaped plate.

[0015] Preferably, two second bases are fixedly installed on the bottom surface of the inner wall of the first outer shell. The top of the second base is provided with a first semi-circular groove, and the inner wall of the second outer shell is provided with a second semi-circular groove. When the second outer shell is fixed to the first outer shell, the combined size of the first semi-circular groove and the second semi-circular groove is adapted to the cross-sectional size of the rotating shaft. The two rotating shafts are far apart from each other and their ends abut against the inner wall of the second outer shell. The height of the second base is higher than the height of the first base.

[0016] Preferably, the second outer shell has two movable grooves not less than the thickness of the vertical portion and movable holes not less than the plane size of the horizontal portion. The movable holes are connected to the movable grooves, and a sealing plate can be detachably fixed inside the movable holes.

[0017] Preferably, a third base is also fixedly installed on the bottom surface of the inner wall of the first housing, and a bushing is fixedly installed on the third base.

[0019] Preferably, a second support rod is detachably and fixedly installed on the top surface of the second housing, and a second massage head is detachably and fixedly connected to both ends of the second support rod. When the first drive assembly drives the sliding member to move horizontally within the housing, the height of the second massage head is not higher than the height of the first massage head.

[0020] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0021] When the first drive assembly is adjusted to drive the slider to move horizontally within the housing, the slider drives the support and the rotating shaft to rotate around the center line of the rotating shaft, thereby causing the first massage head to make an arc-shaped ejection motion. By setting the first drive assembly and the slider horizontally within the housing, compared with the existing drive assembly (transmission screw) and arc-shaped gear component set perpendicular to the top surface of the walking frame, the volume of the entire massage mechanism is greatly reduced, making the structure of the entire massage mechanism more compact and small.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0029] like Figures 1-3 As shown, this utility model provides a compact and small massage mechanism, 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 mounted inside the housing 1;

[0031] The adjustment mechanism 4 includes a first drive assembly and a slider 45 horizontally disposed inside the housing 1. The first drive assembly drives the slider 45 to move horizontally within 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. The other end of the support member 2 is movably connected to the sliding member 45.

[0033] When the first drive assembly is adjusted to drive the slider 45 to move horizontally within the housing 1, the slider 45 drives the support 2 and the rotating shaft 5 to rotate around the center line of the rotating shaft 5, thereby causing the first massage head 31 to make an arc-shaped ejection movement. By horizontally setting the first drive assembly and the slider 45 within the housing 1, compared with the existing drive assembly (transmission screw 44) and arc-shaped gear component that are set perpendicular to the top surface of the walking frame, the volume of the entire massage mechanism is greatly reduced, making the structure of the entire massage mechanism more compact and small.

[0034] like Figure 2 As shown, the adjustment mechanism 4 also includes a connecting rod 46. The first drive assembly includes a first motor 41, a first worm 42, a first worm wheel 43, and a lead screw 44. The first motor 41 is horizontally fixedly installed inside the housing 1. The output end of the first motor 41 is fixedly connected to the first worm 42. The lead screw 44 is horizontally rotatably provided inside the housing 1. One end of the lead screw 44 is detachably fixedly connected to the first worm wheel 43. The first worm wheel 43 and the first worm 42 mesh. The outer surface of the lead screw 44 is helically engaged with a sliding member 45. Both ends of the sliding member 45 are hinged to connecting rods 46. 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 and extending in an arc around the center line of the rotating shaft 5 is as follows: The first motor 41 is activated by a timed forward / reverse switching mechanism, causing the first motor 41 to drive the first worm gear 42 to rotate in both directions. This, in turn, causes the first worm wheel 43 to rotate in both directions, which in turn drives the lead screw 44 to rotate in both directions. This, in turn, causes the sliding member 45 to reciprocate on the lead screw 44. Since the sliding member 45 is hinged to the connecting rod 46, and one end of the connecting rod 46 is hinged to the other end of the support member 2, the sliding member 45 will simultaneously drive the connecting rod 46 to move horizontally. Furthermore, the end of the connecting rod 46 that is hinged to the support member 2 swings in an arc, 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 lead screw 44 and the sliding member 45 avoids the high precision requirements of the machining and installation of the arc-shaped gear member and rack compared to the transmission between the existing arc-shaped gear member and rack, thus saving manufacturing costs. At the same time, it prevents the gear and rack from wearing out during use, which would lead to a relatively short service life.

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

[0037] By dividing the housing 1 into three parts—a first outer shell 11, a second outer shell 12, and a third outer shell 13—and fixing the circuit board 6 between the second outer shell 12 and the third outer shell 13, while the first drive assembly is located between the first outer shell 11 and the second outer shell 12, the third outer shell 13 can be disassembled separately when the circuit board 6 is damaged and needs repair or replacement. This allows for the individual disassembly and replacement of the circuit board 6, avoiding the situation in traditional massage devices where the circuit board 6 and drive structures such as the motor are placed together between the first outer shell 11 and the second outer shell 12. In such cases, when the circuit board 6 needs repair, the drive structures such as the motor are exposed to the air, allowing dust and impurities to fall onto them. This can affect the motor's heat dissipation and increase the resistance of the drive structures (such as the first worm 42, the first worm wheel 43, and the lead screw 44), reducing transmission efficiency, decreasing transmission accuracy, and even causing 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 outer shell 11. Fixed seats 112 are detachably fixedly installed on the first bases 111. The lead screw 44 is rotatably inserted between the two fixed seats 112. The connecting rod 46 and the sliding member 45 both have gaps with the bottom surface of the inner wall of the first outer shell 11.

[0039] By setting the first base 111 and the fixed seat 112, the lead screw 44 can be disassembled and assembled, so that when the lead screw 44 is damaged, it is convenient to quickly disassemble and replace it. In addition, after assembling the fixed seat 112, the lead screw 44 is in a suspended state, and the connecting rod 46 and the sliding member 45 have gaps with the bottom surface of the inner wall of the first housing 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 housing 11 during the movement.

[0040] like Figure 2 and Figure 3As shown, the support member 2 is a U-shaped plate, which includes two vertical parts 21 and a horizontal part 22. With this arrangement, the vertical parts 21 can fix the rotating shaft 5, and the horizontal part 22 can fix the first support rod 3. The horizontal part 22 is located outside the housing 1 and can be detachably fixed to the first support rod 3 (here it can be fixed by screws). The first massage head 31 can be detachably fixed to both ends of the first support rod 3 (the specific detachable fixed connection method of the first massage head 31 and the second massage head 32 mentioned below can be referred to the fixing component of a heated massager with an up and down adjustment device with authorization announcement number CN221655068U). There are two rotating shafts 5, which are symmetrically fixed on both sides of the U-shaped plate.

[0041] By setting two rotating shafts 5 and fixing them symmetrically on both sides of the U-shaped plate, material costs are saved and the weight of the entire massage mechanism is reduced. In addition, the overall volume of the massage mechanism can be further reduced. When a single rotating shaft 5 is fixed through the U-shaped plate, the height of the second base 113 needs to be increased or the distance between the rotating shaft 5 and the fixed seat 112 needs to be lengthened to ensure that the rotating shaft 5 and the fixed seat 112 do not come into contact, which would increase the overall volume of the massage mechanism.

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

[0043] With the first semicircular groove 1131 and the second semicircular groove configured in this way, the rotating shaft 5 can be well limited when the second outer shell 12 is assembled with the first outer shell 11, 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, the second outer shell 12 can be removed, so that the rotating shaft 5 can be quickly taken out and replaced.

[0044] like Figure 2 and Figure 3As shown, the second outer shell 12 has two movable grooves 121 with a thickness not less than that of the vertical part 21 and movable holes 122 with a size not less than that of the horizontal part 22. The movable holes 122 are connected to the movable grooves 121, and the sealing plate 123 can be detachably fixed inside the movable holes 122.

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

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

[0047] By setting the bushing 10, the lead screw 44 is assisted in centering and further supported, avoiding impurities and debris between the fixed seat 112 and the first base 111 when the fixed seat 112 is installed. This makes the fixed seat 112 fixed on the first base 111 slightly higher, thus avoiding the situation where the first worm gear 43 and the first worm 42 cannot mesh after the lead screw 44 is fixed.

[0048] like Figure 5 As shown, each of the two fixed seats 112 has a positioning groove that matches the size of the insertion part on one side. The first worm gear 43 has a first through hole 431 that matches the size of the insertion part. The insertion part has a second through hole 441 along the direction perpendicular to the lead screw 44. A limiting rod 442 is movably inserted into the second through hole 441. A limiting groove 432 that matches the size of the limiting rod 442 is opened on one side of the first worm gear 43. The limiting groove 432 communicates with the first through hole 431. A wear-resistant ring 14 is provided between the first worm gear 43 and the fixed seat 112.

[0049] The specific assembly principle of the lead screw 44 and the first worm gear 43 is as follows: One end of the lead screw 44 is inserted into a positioning groove on a fixed base 112. Then, a limiting rod 442 is inserted into the second through hole 441. Next, the first worm gear 43 is sleeved onto the outer surface of the insertion part, allowing the limiting rod 442 to enter the limiting groove 432, thus completing the initial positioning of the first worm gear 43. Finally, after inserting the wear-resistant ring 14, the other end of the insertion part is inserted into a positioning groove on another fixed base 112. At this point, the wear-resistant ring 14 is positioned on both sides of the first worm gear 43 and the fixed base, respectively. The first worm gear 43 is fixed in place by the limiting rod 442 and the wear-resistant ring 14. Then, the two fixing seats 112, which are assembled with the lead screw 44 and the first worm gear 43, are fixed to the first base 111 with screws. That is, the lead screw 44 is horizontally fixed to the first housing 11. With this setting, when the first worm gear 43 or the lead screw 44 is worn or damaged, it can be disassembled and replaced separately. This avoids the waste of materials caused by replacing the whole when the first worm gear 43 and the lead screw 44 are a non-removable whole.

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

[0051] When in use, the massage mechanism is placed on a long base with a long groove. The long groove is equipped with a gear rail that matches the driving gear 7 and the driven gear 8 (this is an existing structure). By setting up the drive mechanism 9, the massage mechanism can move along the gear rail within the long groove of the long base. Thus, when a person lies on the long base, a comprehensive massage can be performed on their back. Here, the second worm gear 93 and the first gear 94 are set to rotate concentrically, and the second gear 95 and the third gear 96 are set to rotate concentrically. Through the deceleration of these two sets of gears, the rotation speed of the driving gear 7 is reduced, that is, the speed at which the massage mechanism moves along the gear rail within the long groove of the long base is reduced, thus making the massage more comfortable for people.

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

[0053] When the first drive assembly drives the slider 45 to move horizontally within the housing 1, the height of the second massage head 32 is not higher than the height of the first massage head 31. When the first drive assembly drives the slider 45 to move horizontally within the housing 1 so that the first massage head 31 moves to the same height as the second massage head 32, the first massage head 31 and the second massage head 32 can massage together. When the first drive assembly drives the slider 45 to move horizontally within the housing 1 so that the height of the first massage head 31 gradually exceeds the height of the second massage head 32, the first massage head 31 plays the role of pushing out massage.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
