Description

Technical Field

[0001] This utility model relates to the field of massage mechanism, specifically a single-motor multi-purpose massage mechanism. Background Technology

[0002] Existing massage mechanisms typically use multiple motors to drive the kneading mechanism, tapping mechanism, and walking mechanism respectively. Although this mechanism structure can achieve multiple massage functions, the arrangement of different motors on the base plate can easily result in a large overall thickness of the mechanism, which is not conducive to installation in small massage devices.

[0003] To reduce the thickness of the massage mechanism and optimize its structure, solutions using a single motor to drive multiple components have emerged on the market. For example, Chinese patent application CN201510498026.8 discloses a multi-purpose, lightweight massage mechanism that drives a kneading mechanism and a tapping mechanism separately through different output structures at both ends of the motor. However, this solution still has significant shortcomings. For instance, the massage motor and the tapping transmission mechanism use helical gear transmission, which has poor impact resistance and is prone to wear under the high-frequency vibration of the tapping transmission mechanism, leading to transmission failure. The kneading transmission mechanism is mounted on the kneading shaft via an eccentric bushing, which is inconvenient for assembly. In addition, in this solution, the massage motor and the kneading transmission mechanism are driven by a combination of worm gear and multi-stage gears, resulting in a long transmission chain, low efficiency, and insufficient torque output, which cannot meet the power requirements for deep kneading. Utility Model Content

[0004] The purpose of this utility model is to provide a single-motor multi-purpose massage mechanism that can realize multiple massage functions through a single motor, and has the advantages of high power output, stable transmission structure, and good applicability.

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

[0006] A single-motor multi-purpose massage mechanism is mounted on a massage frame and includes a base plate, a walking mechanism, a kneading mechanism, and a tapping mechanism. The walking mechanism is mounted on the base plate and is used to drive the base plate to move relative to the massage frame. The kneading mechanism is mounted on the base plate and is used to perform kneading. The tapping mechanism is mounted on the base plate and connected to the kneading mechanism to drive the kneading mechanism to perform tapping.

[0007] It also includes a dual-output shaft motor, a drive shaft, and a compound gear;

[0008] The dual-output-shaft motor is mounted on the base plate, with a first output shaft and a second output shaft extending vertically at its upper and lower ends, respectively; a first worm gear is fixedly connected to the first output shaft, and a first gear is fixedly connected to the second output shaft.

[0009] The drive shaft is arranged horizontally and rotatably mounted on the base plate via bearings. A first worm gear is fixed on the drive shaft. The first worm gear meshes with a first worm to drive the drive shaft to rotate.

[0010] Both the kneading mechanism and the walking mechanism are connected to the transmission shaft. When the transmission shaft rotates, it drives the kneading mechanism to perform kneading and causes the walking mechanism to move the base plate.

[0011] The compound gear is rotatably mounted on the base plate via bearings, and the striking mechanism is provided with a striking transmission wheel. The first gear and the striking transmission wheel are connected by the compound gear.

[0012] When the second output shaft rotates, it is sequentially driven by the first gear, the compound gear and the striking transmission wheel, so that the striking mechanism drives the kneading mechanism to achieve striking.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] 1. By using worm gear transmission between the dual-output shaft motor and the transmission shaft, the kneading force of the kneading mechanism and the walking stability of the walking mechanism are significantly improved. In addition, through the cooperation of the first gear, compound gear and the striking transmission wheel, the striking mechanism maintains reliable transmission under high-frequency striking conditions, disperses the impact load, reduces gear wear, and has the advantages of good striking stability and high durability.

[0015] 2. Through the cooperation of the integrated first output shaft, second output shaft and one-way bearing, the kneading, tapping and kneading-tapping functions can be controlled by the forward and reverse rotation of the dual output shaft motor, which reduces the overall size of the mechanism and simplifies the mechanism transmission structure.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] like Figure 1-10 The image shown is a schematic diagram of an embodiment of a single-motor multi-purpose massage mechanism provided by this utility model:

[0029] A single-motor multi-purpose massage mechanism is mounted on a massage frame and includes a base plate 1, a walking mechanism 2, a kneading mechanism 3, and a tapping mechanism 4. The walking mechanism 2 is mounted on the base plate 1 and is used to drive the base plate 1 to move relative to the massage frame. The kneading mechanism 3 is mounted on the base plate 1 and is used to perform kneading. The tapping mechanism 4 is mounted on the base plate 1 and connected to the kneading mechanism 3, and is used to drive the kneading mechanism 3 to perform tapping.

[0030] It also includes a dual-output shaft motor 5, a drive shaft 6, and a compound gear 7;

[0031] The dual-output-shaft motor 5 is mounted on the base plate 1, and its upper and lower ends are respectively provided with a first output shaft and a second output shaft extending vertically; a first worm gear 51 is fixedly connected to the first output shaft, and a first gear 70 is fixedly connected to the second output shaft.

[0032] The drive shaft 6 is arranged horizontally and is rotatably mounted on the base plate 1 through bearings. A first worm wheel 60 is fixed on the drive shaft 6. The first worm wheel 60 meshes with the first worm 51 to drive the drive shaft 6 to rotate.

[0033] Both the kneading mechanism 3 and the walking mechanism 2 are connected to the transmission shaft 6. When the transmission shaft 6 rotates, it drives the kneading mechanism 3 to perform kneading and causes the walking mechanism 2 to drive the base plate 1 to move.

[0034] The compound gear 7 is rotatably mounted on the base plate 1 via a bearing, and the striking mechanism 4 is provided with a striking transmission wheel 41. The first gear 70 and the striking transmission wheel 41 are connected by the compound gear 7.

[0035] When the second output shaft rotates, it is sequentially driven by the first gear 70, the compound gear 7, and the striking transmission wheel 41, so that the striking mechanism 4 drives the kneading mechanism 3 to perform striking.

[0036] In this embodiment, the first gear 70 is an active bevel gear, the striking transmission wheel 41 is a passive spur gear, and the compound gear 7 includes a passive bevel gear 71 that meshes and rotates with the active bevel gear and an active spur gear 72 that meshes and transmits power with the passive spur gear. The passive bevel gear 71 and the active spur gear 72 are coaxially fixedly connected.

[0037] In some embodiments, the first gear 70 is a driving bevel gear, and the compound gear 7 includes a driven bevel gear 71 that meshes with and rotates with the driving bevel gear, as well as other transmission structures that are connected to the striking transmission wheel 41. For example, when the striking transmission wheel 41 is a driven pulley, the compound gear 7 includes a driven bevel gear 71 and a driving pulley, and the driven bevel gear 71 and the driving pulley are coaxially fixedly connected, and the driving pulley and the driven pulley are connected by a belt drive; when the striking transmission wheel 41 is a driven sprocket, the compound gear 7 includes a driven bevel gear 71 and a driving sprocket, and the driven bevel gear 71 and the driving sprocket are coaxially fixedly connected, and the driving sprocket and the driven sprocket are connected by a chain drive.

[0038] The drive shaft 6 includes a main shaft section 61, two kneading shaft sections 62, and two traveling shaft sections 63.

[0039] The first worm gear 60 is mounted on the main shaft section 61, the two kneading shaft sections 62 are respectively located at both ends of the main shaft section 61, and the two traveling shaft sections 63 are respectively connected to the ends of the two kneading shaft sections 62;

[0040] In this embodiment, the main shaft section 61, the kneading shaft section 62, and the walking shaft section 63 are coaxially arranged;

[0041] The kneading mechanism 3 is connected to the kneading shaft section 62 via an eccentric bushing 64.

[0042] The kneading mechanism 3 includes two transmission arms 31 and two massage arms 32. The middle sections of the two transmission arms 31 are respectively mounted on the corresponding kneading shaft sections 62 on both sides through eccentric bushings 64. The front ends of the transmission arms 31 are hinged to the massage arms 32. The kneading shaft sections 62 rotate and drive the transmission arms 31 and massage arms 32 to reciprocate, thereby realizing kneading.

[0043] In one embodiment, the kneading shaft section 62 is eccentrically arranged relative to the main shaft section 61, and the kneading mechanism 3 is mounted on the kneading shaft section 62;

[0044] The two walking shaft segments 63 are respectively disposed at the ends of the two kneading shaft segments 62, and the central axis of the walking shaft segment 63 and the main shaft segment 61 are on the same straight line. The walking mechanism 2 is connected to the walking shaft segment 63.

[0045] In this embodiment, the kneading mechanism 3 does not need to be used with the eccentric bushing 64; only the pre-machined drive shaft 6 needs to be purchased, which reduces the number of parts to be assembled and optimizes the cost.

[0046] The massage arm 32 includes an arc-shaped frame 321 and two massage rollers 322. The two massage rollers 322 are respectively installed at the upper and lower ends of the arc-shaped frame 321, and the middle part of the arc-shaped frame 321 is hinged to the front end of the transmission arm 31.

[0047] The walking mechanism 2 includes two active walking wheels 21, two walking teeth 22, a rotating shaft 23, and two passive walking wheels 24;

[0048] The two active walking wheels 21 are respectively installed at the ends of the two walking shaft sections 63 on both sides, and the two walking teeth 22 are respectively sleeved on the outer side of the two walking shaft sections 63 on both sides.

[0049] The rotating shaft 23 is parallel to the traveling shaft section 63 and is mounted on the lower part of the base plate 1 through bearings. The two passive traveling wheels 24 are respectively installed at both ends of the rotating shaft 23.

[0050] The walking gear 22 is engaged with the massage frame and is used to drive the active walking wheel 21 and the passive walking wheel 24 to walk on the massage frame.

[0051] The striking mechanism 4 includes a striking rotating shaft 42 and two striking transmission components 43;

[0052] The striking transmission wheel 41 is mounted on the striking rotating shaft 42. Both ends of the striking rotating shaft 42 are provided with striking eccentric shafts 44. The two striking transmission components 43 are respectively mounted on the striking eccentric shafts 44 on both sides and are hinged to the lower end of the transmission arm 31 on the corresponding side.

[0053] The dual-output shaft motor 5 drives the striking rotating shaft 42 and the striking eccentric shaft 44 to rotate, and drives the striking transmission assembly 43 to reciprocate, thereby pushing the transmission arm 31 to perform striking.

[0054] The striking transmission assembly 43 includes a striking bearing 431 and a universal ball joint connecting rod 432. The striking bearing 431 is mounted on the striking eccentric shaft 44. The ball joint end of the universal ball joint connecting rod 432 is hinged to the lower end of the transmission arm 31, and its other end is hinged to the outer side of the striking bearing 431.

[0055] The first output shaft and the second output shaft of the dual-output shaft motor 5 are integrally formed;

[0056] When the first output shaft and the second output shaft of the dual-output shaft motor 5 rotate in the forward direction, the dual-output shaft motor 5 simultaneously drives the kneading mechanism 3, the walking mechanism 2 and the striking mechanism 4.

[0057] The striking transmission wheel 41 is mounted on the striking rotating shaft 42 via a one-way bearing 45. When the first output shaft and the second output shaft of the dual-output shaft motor 5 rotate in opposite directions, the one-way bearing 45 is used to ensure that the dual-output shaft motor 5 drives the kneading mechanism 3 and the walking mechanism 2 simultaneously.

[0058] Preferably, the one-way bearing 45 is a one-way needle roller bearing.

[0059] The base plate 1 has clearance openings 100 corresponding to the striking transmission components 43 and transmission arms 31 on both sides.

[0060] The working principle of this utility model is roughly as follows:

[0061] A first worm gear 51 is fixedly connected to the first output shaft at the upper end of the dual-output shaft motor 5. The first worm gear 51 meshes with the first worm wheel 60, thereby driving the transmission shaft 6 to rotate. The transmission shaft 6 further drives the kneading mechanism 3 and the walking mechanism 2. Since the dual-output shaft motor 5 and the transmission shaft 6 adopt worm gear transmission, it has the characteristics of large reduction ratio, short transmission chain and high torque output, which significantly improves the kneading force of the kneading mechanism 3 and the running stability of the walking mechanism 2, effectively solving the problem of insufficient kneading force and walking vibration caused by the use of worm gear and multi-stage gear transmission in traditional massage mechanisms.

[0062] A first gear 70 is mounted on the second output shaft at the lower end of the dual-output-shaft motor 5. The first gear 70 acts as a driving bevel gear, meshing with the driven bevel gear 71 in the compound gear 7. The driven bevel gear 71 is coaxially fixed with the driving spur gear 72. The driving spur gear 72 further drives the striking transmission wheel 41, achieving stable multi-stage gear transmission. This multi-stage transmission structure can effectively disperse the impact load generated by the striking mechanism 4 during high-frequency striking, thereby significantly improving the durability and reliability of the striking transmission.

[0063] Specifically, when the dual-output shaft motor 5 rotates in the forward direction, the first output shaft drives the first worm wheel 60 via the first worm 51, causing the transmission shaft 6 to rotate. The transmission shaft 6 drives the transmission arm 31 and the massage arm 32 to swing back and forth through the kneading shaft section 62, realizing the kneading action. At the same time, it drives the active walking wheel 21 through the walking shaft section 63 and the walking gear 22, causing the base plate 1 to move along the massage frame. Meanwhile, the second output shaft transmits power sequentially through the first gear 70, the compound gear 7 and the tapping transmission wheel 41, causing the tapping rotating shaft 42 and the tapping eccentric shaft 44 to rotate synchronously, and driving the tapping transmission component 43 to move, thereby enabling the massage mechanism to realize the kneading and tapping massage function.

[0064] Since the striking transmission wheel 41 is mounted on the striking rotating shaft 42 via a one-way bearing 45, when the dual-output shaft motor 5 rotates in the reverse direction, the one-way bearing 45 is in an idle state, and the striking mechanism no longer outputs work. At this time, the first output shaft still drives the first worm wheel 60 and the transmission shaft 6 via the first worm 51, causing the kneading mechanism 3 to continue performing the kneading action, and causing the walking mechanism 2 to drive the base plate 1 to move. In summary, the massage mode can be switched by controlling the forward and reverse rotation of the dual-output shaft motor 5.

[0065] 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.
