Description

Technical Field

[0001] This utility model relates to the field of massage mechanism, specifically a novel ultra-thin mechanism. Background Technology

[0002] Currently, massage mechanisms on the market typically consist of a walking mechanism and a massage mechanism, which enable the movement and massage of the mechanism. To ensure the walking efficiency of the mechanism, most existing walking mechanisms employ a worm gear transmission structure. However, because the axes of the worm and worm wheel must be perpendicular when meshing, the output shaft of the walking motor usually needs to be arranged perpendicular to the main shaft. This structural limitation results in the entire walking mechanism occupying a large amount of space in the longitudinal direction of the mechanism, leading to a relatively long overall structure length.

[0003] In order to minimize the overall length of the movement, existing movements use a stacked design for the various motors, reduction gears, and drive shafts. However, this significantly increases the thickness of the movement, making it difficult to further compress it in the thickness direction.

[0004] Therefore, existing massage mechanisms are generally too thick, making them unsuitable for the increasing number of small massage chairs, home products, and in-car massage scenarios. This severely limits the compatibility and installation space of the mechanisms, preventing them from meeting the design requirements of being thinner and more compact. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of ultra-thin movement, which has a compact and lightweight overall structure, stable transmission, avoids the defects of excessive thickness caused by stacking of transmission structures in existing movements, and has good applicability.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A novel ultra-thin mechanism is installed on a massage frame, comprising a base plate, a walking mechanism, and a massage mechanism; the massage mechanism is installed on the base plate for performing massage, and the walking mechanism is installed on the base plate for driving the base plate to move relative to the massage frame.

[0008] The walking mechanism includes a walking motor, a walking gearbox, and a drive walking wheel assembly;

[0009] The active walking wheel assembly includes a main shaft rotatably connected to the base plate, a fourth transmission component fixedly provided in the middle of the main shaft, and walking units that cooperate with the massage frame fixedly provided at both ends of the main shaft.

[0010] The walking motor is mounted on the base plate and located next to the main shaft. The output shaft of the walking motor is parallel to the main shaft, and a first transmission component is coaxially fixed on its output shaft.

[0011] The travel reduction gearbox is connected between the first transmission component and the fourth transmission component.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. By setting the output shaft of the walking motor parallel to the main rotating shaft, setting the transmission shaft perpendicular to the main rotating shaft, and using the transmission cooperation between the first and fourth transmission components of the double-shaft gear assembly, the stacking design of the traditional mechanism transmission structure is avoided. This allows the mechanism to effectively shorten its overall length and reduce its overall thickness, making it suitable for small massage chairs, home products, and in-vehicle massage devices.

Detailed Implementation

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

[0025] like Figure 1-9 The image shown is a schematic diagram of an embodiment of a novel ultra-thin movement provided by this utility model:

[0026] A novel ultra-thin mechanism is installed on a massage frame, comprising a base plate 1, a walking mechanism 2, and a massage mechanism; the massage mechanism is installed on the base plate 1 for performing massage, and the walking mechanism 2 is installed on the base plate 1 for driving the base plate 1 to move relative to the massage frame.

[0027] The walking mechanism 2 includes a walking motor 21, a walking reduction gearbox 22, and an active walking wheel assembly 23;

[0028] The active walking wheel assembly 23 includes a main shaft 231 rotatably connected to the base plate 1, a fourth transmission component 232 fixedly provided in the middle of the main shaft 231, and walking units that cooperate with the massage frame fixedly provided at both ends of the main shaft 231.

[0029] The walking motor 21 is mounted on the base plate 1 and located next to the main rotating shaft 231. The output shaft of the walking motor 21 is parallel to the main rotating shaft 231, and a first transmission component 211 is coaxially fixed on its output shaft.

[0030] The travel reduction gearbox 22 is connected between the first transmission component 211 and the fourth transmission component 232.

[0031] The traveling reduction gearbox 22 includes a housing 221 and a double-shaft gear assembly; the double-shaft gear assembly includes a second transmission component 222, a third transmission component 223, and a transmission shaft 224 rotatably mounted in the housing 221; the transmission shaft 224 is perpendicular to the main rotating shaft 231, the second transmission component 222 and the third transmission component 223 are coaxially arranged on the transmission shaft 224, and the first transmission component 211 is connected to the second transmission component 222, and the third transmission component 223 is connected to the fourth transmission component 232.

[0032] In this embodiment, the first transmission component 211 is a transmission worm, the second transmission component 222 is a transmission worm wheel, and the first transmission component 211 and the second transmission component 222 are meshed together; the third transmission component 223 is a driving bevel gear, the fourth transmission component 232 is a driven bevel gear, and the third transmission component 223 and the fourth transmission component 232 are meshed together.

[0033] The output shaft of the walking motor 21 is parallel to the main rotating shaft 231, while the transmission shaft 224 is perpendicular to the main rotating shaft 231. It is connected between the first transmission component 211 and the fourth transmission component 232 through a double-shaft gear assembly, which effectively shortens the overall length of the mechanism and avoids the stacking of the transmission structure, significantly reducing the thickness of the mechanism and making the overall structure of the mechanism flatter and more compact. This is beneficial for installation and use in small massage chairs, home massage products, and vehicle massage devices.

[0034] Furthermore, the double-shaft gear assembly adopts a two-stage meshing transmission of worm gear and bevel gear. The worm gear transmission of the first transmission component 211 and the second transmission component 222 has the characteristics of strong self-locking, smooth transmission, and large reduction ratio, which can realize stable primary reduction of the main shaft 231. The second transmission component 222 and the third transmission component 223 are arranged coaxially, and the second-stage reduction is completed through the bevel gear meshing of the third transmission component 223 and the fourth transmission component 232. This makes the output torque of the main shaft 231 larger and more stable, and can also effectively reduce the load on the travel motor 21, thereby improving the overall reliability and service life.

[0035] Furthermore, the first transmission component 211 may also be a spur gear, bevel gear, etc., and the second transmission component 222 may be a spur gear, bevel gear, etc. that matches the first transmission component 211;

[0036] The third transmission component 223 and the fourth transmission component 232 may also be selected as mutually matched interlocking helical gears.

[0037] The walking unit includes an active walking wheel 233 and a walking tooth 234. The active walking wheel 233, the walking tooth 234 and the main rotating shaft 231 are coaxially arranged.

[0038] The walking mechanism 2 also includes a passive walking wheel assembly 24, which includes a rotating shaft 241 and two passive walking wheels 242. The passive walking wheels 242 are respectively disposed at both ends of the rotating shaft 241. The rotating shaft 241 is mounted on the base plate 1 by bearings, and the rotating shaft 241 is parallel to the main rotating shaft 231.

[0039] The massage mechanism includes a kneading unit 3 and a tapping unit 4. The tapping unit 4 is connected to the kneading unit 3 and is used to drive the kneading unit 3 to perform tapping.

[0040] The kneading unit 3 includes a kneading motor 31, a kneading shaft 32, and two transmission arms 33.

[0041] The kneading motor 31 is mounted on the base plate 1, and its output end is fixedly connected to the second worm gear 311. The kneading shaft 32 is rotatably mounted on the base plate 1 and is parallel to the main rotating shaft 231. The kneading shaft 32 is equipped with a second worm wheel 321, and the second worm wheel 321 is meshed with the second worm gear 311.

[0042] Both ends of the kneading shaft 32 are obliquely provided with stepped shafts 34. The middle sections of the two transmission arms 33 are respectively mounted on the corresponding stepped shafts 34 on both sides through bearings. The upper end of the transmission arm 33 is connected to the massage arm 35. The kneading motor 31 drives the kneading shaft 32 to rotate and drives the transmission arm 33 and the massage arm 35 to reciprocate, thereby realizing kneading.

[0043] The massage arm 35 includes an arc-shaped frame 351 and two massage rollers 352. The two massage rollers 352 are respectively installed at both ends of the arc-shaped frame 351, and the middle part of the arc-shaped frame 351 is hinged to the upper end of the transmission arm 33.

[0044] The striking unit 4 includes a striking motor 41, a striking rotating shaft 42, a driving pulley 43, a driven pulley 44, and two striking transmission components 45;

[0045] The striking motor 41 is mounted on the base plate 1, and the driving pulley 43 is fixed on the output shaft of the striking motor 41; the striking rotating shaft 42 is coaxially connected to the driven pulley 44 and rotatably mounted on the base plate 1, and the driving pulley 43 and the driven pulley 44 are connected by belt drive.

[0046] Both ends of the striking rotating shaft 42 are provided with striking eccentric shafts 46, and two striking transmission components 45 are respectively installed on the striking eccentric shafts 46 on both sides and are hinged to the bottom end of the transmission arm 33 on the corresponding side.

[0047] The striking motor 41 drives the striking rotating shaft 42 and the striking eccentric shaft 46 to rotate, and drives the striking transmission assembly 45 to reciprocate, thereby pushing the transmission arm 33 to perform striking.

[0048] The striking transmission assembly 45 includes a striking bearing 451 and a universal ball joint connecting rod 452. The striking bearing 451 is mounted on the striking eccentric shaft 46. The ball joint end of the universal ball joint connecting rod 452 is hinged to the bottom end of the transmission arm 33, and its other end is hinged to the outer side of the striking bearing 451.

[0049] The base plate 1 has clearance openings 100 corresponding to the striking transmission components 45 and transmission arms 33 on both sides.

[0050] The working principle of this utility model is roughly as follows:

[0051] This utility model has the functions of kneading, tapping, kneading and tapping, and kneading, tapping, kneading and tapping when the object is moved.

[0052] When the kneading motor 31 starts, the second worm gear 311 on the output shaft of the kneading motor 31 drives the second worm wheel 321 on the kneading shaft 32 to rotate. The kneading shaft 32 rotates accordingly and drives the stepped shafts 34 at both ends to make eccentric movements. The transmission arm 33 installed on the stepped shaft 34 swings back and forth accordingly, so that the massage arm 35 at the upper end of the transmission arm 33 kneads the user.

[0053] When the tapping motor 41 is started, the tapping motor 41 drives the tapping rotating shaft 42 to rotate through the driving belt pulley 43 and the driven belt pulley 44. The tapping eccentric shafts 46 at both ends of the tapping rotating shaft 42 generate eccentric oscillation, which drives the tapping transmission assembly 45 to reciprocate. Since the tapping transmission assembly 45 is hinged to the transmission arm 33, when the tapping transmission assembly 45 moves, it drives the transmission arm 33 to swing together, so that the massage arm 35 taps the human body.

[0054] When the striking motor 41 and the kneading motor 31 start together, the transmission arm 33 adds a striking action on the basis of the kneading action, so as to achieve the joint work of kneading and striking.

[0055] When the walking motor 21 is started, the first transmission component 211 on the output shaft of the walking motor 21 drives the double-shaft gear assembly in the walking reduction gearbox 22 to rotate. The double-shaft gear assembly then drives the main rotating shaft 231 to rotate. The walking units at both ends of the main rotating shaft 231 cooperate with the rack and guide rail on the massage frame to make the base plate 1 move on the massage frame. At this time, the tapping motor 41 and the kneading motor 31 are turned on to realize the kneading, tapping or kneading and tapping action of the movement during the movement.

[0056] 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.
