Description

Technical Field

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

[0002] As society develops, people face increasing work pressure. Whether they can get enough rest and relaxation after work will directly affect their work performance the next day.

[0003] As a result, massage devices that can be used at home are becoming increasingly popular. Existing home massage devices, such as fascia guns, stimulate deep muscles through high-frequency vibrations, increasing blood flow to tissues and relaxing muscles, thus relieving discomfort caused by prolonged sitting. However, high-frequency vibrations, especially with prolonged use, may cause discomfort to some users. Summary of the Invention

[0004] In view of this, the present invention aims to provide a multi-joint massage mechanism that creates a patting-like massage effect on the human body, making the user experience more comfortable.

[0005] A multi-joint massage mechanism includes a massage component and a drive component connected to the massage component. The massage component includes a plurality of massage joints arranged in sequence, with adjacent massage joints rotatably connected. The drive component includes a motor and a traction rope, one end of which is connected to the motor and the other end of which is connected to the end massage joint of the massage component. When the traction rope is wound or released, the adjacent massage joints rotate relative to each other, causing the massage component to switch to a first mode or a second mode.

[0006] Compared to existing technologies, the multi-joint massage mechanism provided by this invention allows each massage joint to rotate relative to the others by winding or releasing the traction rope, thereby changing the shape of the massage components. This enables the ends of the massage components to swing back and forth and pat the massaged area, resulting in a more comfortable user experience. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. One or more embodiments of this utility model are exemplarily shown in the drawings to enable a more accurate and thorough understanding of the disclosed technical solutions. However, it should be understood that this utility model can be implemented in many different forms and is not limited to the embodiments described below.

[0021] This utility model provides a multi-joint massage mechanism that, when in use, acts on parts of the human body that require massage, such as the shoulders and neck, back, limbs, waist and abdomen. Figure 1-3The figure shown is a multi-joint massage mechanism 100 according to a specific embodiment of the present invention, which includes a massage component 20 and a drive component 30.

[0022] The massage component 20 is formed by sequentially connecting N massage joints 22, where N is an integer greater than 1. Each massage joint 22 is approximately hollow cylindrical, and the massage component 20 formed by the N massage joints 22 is generally rod-shaped. Adjacent massage joints 22 are rotatably connected, allowing the massage component 20 to have different first and second forms. In the first form, as... Figure 1-3 As shown, the massage component 20 is generally in the shape of a curved rod; in the second configuration, as... Figure 7-8 As shown, the massage component 20 is generally in the shape of a straight rod.

[0023] For ease of description, such as Figure 4 As shown, the massage joints 22 are sequentially referred to as the first joint 221, the second joint 222, the third joint 223, ..., the Nth joint 22N. The first joint 221 serves as the connection end of the massage assembly 20 and is connected to other components of the massage mechanism 100, such as the housing 32 of the drive assembly 30. The Nth joint 22N is located at the end of the massage assembly 20 and is suspended in the air. Figure 1 In the illustrated embodiment, the number of massage joints 22 is four. In other embodiments, the number of massage joints 22 can be adjusted as needed, such as six, seven, etc.

[0024] Please also refer to Figure 5-6 Each massage joint 22 has a first side end 22a and a second side end 22b that are axially opposite each other, wherein the outer diameter of the first side end 22a is slightly smaller than the inner diameter of the second side end 22b. During assembly, the first side end 22a of the latter massage joint (such as the second joint 222) is movably inserted into the second side end 22b of the adjacent former massage joint (such as the first joint 221), while the first side end 22a of the first joint 221 is inserted into the housing 32.

[0025] To facilitate relative rotation of the massage joints 22, the outer wall surface 22c of the first side end 22a of each massage joint 22 is constructed as part of a first spherical surface, and the inner wall surface 22d of the second side end 22b is constructed as part of a second spherical surface. The outer diameter of the first spherical surface containing the outer wall surface 22c is slightly smaller than the inner diameter of the second spherical surface 22d containing the inner wall surface 22d. Thus, the connection point of the two massage joints 22 forms a ball-head massage joint structure, allowing adjacent massage joints 22 to rotate flexibly relative to each other.

[0026] In this embodiment, each massage joint 22 has a shaft hole 22e at its first side end 22a, and preferably there are two shaft holes 22e symmetrically distributed; each massage joint 22 has a shaft 22f at its second side end 22b, and preferably there are two shafts 22f coaxially arranged. When the massage joints 22 are assembled together, the shaft 22f of the preceding massage joint 22 is rotatably pivotally connected to the corresponding shaft hole 22e of the following massage joint 22, so that two adjacent massage joints 22 can rotate relative to each other about the shaft 22f.

[0027] The first joint 221 and the housing 32 can be rotatably connected in a similar manner. For example, the inner wall surface of the housing 32 facing the first joint 221 can be constructed as part of a sphere, and a shaft 321 can be protruding from this inner wall surface. When the first side end 22a of the first joint 221 is inserted into the corresponding side end of the housing 32, the shaft 321 of the housing 32 is inserted into the shaft hole 22e of the first joint 221, thus rotatably connecting the massage assembly 20 to the housing 32. See [reference needed]. Figure 4 .

[0028] The massage component 20 is rotatably connected to the housing 32, allowing each massage joint 22 to rotate, thus giving the massage component 20 greater flexibility and range of deformation. In some embodiments, the first joint 221 of the massage component 20 can also be fixedly connected to the housing 32 by means of snap-fit, adhesive, screw connection, etc. In this case, although the first joint 221 cannot rotate, the massage component 20 can still achieve shape transformation by rotating the other massage joints 22.

[0029] like Figure 2 , Figure 4 As shown, the drive assembly 30 includes a motor 34, a traction rope 36, and a transmission structure 38 connecting the motor 34 and the traction rope 36. The motor 34 is preferably a geared motor. One end of the traction rope 36 is connected to the motor 34 via the transmission structure 38, and the other end is fixedly connected to the Nth joint 22N. The motor 34 drives the traction rope 36 to wind up or release, thereby causing the massage joints 22 to rotate relative to each other to change the shape of the massage assembly 20. The traction rope 36 is preferably a steel wire rope, possessing both rigidity and flexibility, capable of bending and deforming under stress but not stretching or contracting.

[0030] In this embodiment, the traction rope 36 is wound around the reel 39, and its end forms a loop 361. The loop 361 passes through each massage joint 22 and is sleeved onto the fixed shaft 23 inside the Nth joint 22N. When the motor 34 rotates in the forward direction, the reel 39 can rotate in a predetermined first direction (such as counterclockwise) under the drive of the motor 34, so that the traction rope 36 is further wound around the reel 39, pulling the Nth joint 22N connected thereto, thereby causing each massage joint 22 to rotate relative to the previous massage joint 22 connected thereto, changing the shape of the massage component 20.

[0031] In one embodiment, the massage component 20 is initially in a first configuration, with each massage joint 22 deflected downwards at a certain angle relative to the adjacent preceding massage joint 22, forming an angle between the axes of the massage joints 22, and the end of the massage component 20 bent and drooping. At this time, the traction rope 36 is in a relaxed state.

[0032] When the massage mechanism 100 of this application is started, the starter motor 34 drives the roller 39 to rotate in a first direction. The winding of the traction rope 36 pulls the Nth joint 22N upward, causing each massage joint 22 to swing upward until the massage mechanism 100 as a whole is basically in the shape of a straight rod. At this time, the axes of each massage joint 22 are almost in the same straight line, and the massage component 20 switches to the second mode.

[0033] It should be noted that the massage component 20 involved in this application is in a straight strip shape in the second form, but not in a standard straight strip shape. For example... Figure 7-9 As shown, each massage joint 22 of the massage assembly 20 may be tilted upward at a small angle relative to the previous massage joint 22 connected to it, and the angle between their axes is preferably no more than 5 degrees; the massage assembly 20 as a whole may be slightly tilted upward, and the angle between the axes of its first joint 221 and the Nth joint 22N is preferably no more than 15 degrees.

[0034] Furthermore, the upward and downward directions mentioned in this application are described based on the illustrated directions to facilitate understanding of the technical solution of this application. For actual products, there can be various different placement angles, but generally speaking, the massage component 20 is bent in the first direction in the first configuration; in the second configuration, the massage component 20 is roughly straight and can be slightly bent in the opposite second direction. That is to say, the bending direction and bending amplitude of the massage component 20 are different in the two different configurations.

[0035] In this embodiment, an elastic element 24 is provided inside the massage joint 22. The elastic element 24 is preferably a torsion spring or the like, with its two ends abutting against two adjacent massage joints 22 respectively. When the roller 39 rotates in the first direction under the drive of the motor 34, the relative rotation of each massage joint 22 causes the elastic element 24 to be compressed and deformed, and the traction rope 36 is tightened. After the motor 34 stops, the massage assembly 20 can remain in the second form for a certain period of time, which can be set as needed.

[0036] When the massage structure 100 needs to return to the first state, the motor 34 restarts and drives the roller 39 to rotate in the second direction (such as clockwise) to release the traction rope 36. At this time, the pressure acting on the elastic member 24 disappears, the elastic member 24 recovers its deformation and naturally opens, pushing the massage joint 22 to rotate in the opposite direction to reset, so that the massage assembly 20 returns to the first state.

[0037] In the illustrated embodiment, each massage joint 22 has a protrusion 25 on its inner wall near its second side end 22b. The protrusion 25 is preferably parallel to the shaft 321, and the elastic element 24 is sleeved on the protrusion 25. In addition, each massage joint 22 has a first limiting protrusion 26 on its inner wall at its first side end 22a, and a second limiting protrusion 27 at the axial center of its inner wall. One end of the elastic element 24 in the massage joint 22 abuts against the second limiting protrusion 27, and the other end abuts against the first limiting protrusion 26 of the adjacent massage joint 22.

[0038] After the traction rope 36 is released, when the elastic element 24 recovers its deformation and naturally opens, its two ends respectively push the second limiting protrusion 27 of the massage joint 22 where it is located and the first limiting protrusion 26 of the adjacent subsequent massage joint 22, causing the subsequent massage joint 22 to deflect downward and reset relative to the previous massage joint 22. The first limiting protrusion 26 and the second limiting protrusion 27 can be columnar, plate-shaped, etc., and can stably abut against the elastic element 24.

[0039] like Figure 4 As shown, each massage joint 22 has a guide groove 28 formed inside it for limiting and guiding the traction rope 36. The guide groove 28 can be single or multiple, and can be formed by the intervals between the guide posts 29 protruding from the inner wall of the massage joint 22, and / or by the intervals between the guide posts 29 and the inner wall of the massage joint 22, and / or by the intervals between the limiting protrusions 26, 27 and the inner wall of the massage joint 22. The guide groove 28 is preferably located close to the inner wall of the massage joint 22 so that the traction rope 36 and the elastic element 24 do not interfere with each other.

[0040] In this embodiment, the transmission structure 38 includes a worm gear 381 and a turbine gear 383 that cooperate with each other. The worm gear 381 is sleeved on the output shaft of the motor 34, and the turbine gear 383 is connected to the reel 39. Specifically, the reel 39 and the turbine gear 383 can be a coaxial integral structure. By providing the transmission structure 38, the arrangement of the motor 34 and the reel 39 can be facilitated. In other embodiments, the transmission structure can have other forms, such as belt pulley drive; or, the reel 39 can be directly driven by the motor 34, thus omitting the transmission structure.

[0041] The multi-joint massage mechanism 100 provided in this application allows the massage joints 22 to rotate relative to each other when the traction rope 36 is wound or released, thereby changing the shape of the massage component 20. This allows the ends of the massage component 20 to swing up and down, patting the massaged areas such as the shoulders, neck, back, limbs, and waist and abdomen, achieving the effect of relaxing muscles and soothing the mind and body. Compared with high-frequency vibration, the multi-joint massage mechanism 100 of this application provides a more comfortable user experience and is more beneficial to the user's health.

[0042] It should be noted that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, such as combining different features in various embodiments, and these should all fall within the protection scope of the present invention.
