Description

Technical Field

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

[0002] Compared to manual massage, electric massage devices meet users' massage needs while saving costs, making them popular among consumers.

[0003] Existing electric massage devices achieve massage functions by simulating the kneading and grasping motions of human hands. Their structure includes a rotary drive, a rotating disk, and several tentacles. The rotating disk is equipped with a variable-diameter cam channel, and each tentacle is inserted into the channel through a connecting post. When the rotary drive drives the rotating disk to rotate, the variable-diameter cam channel guides the displacement of the connecting post through trajectory changes, driving the tentacles to swing in and out to achieve the massage action.

[0004] However, in this design, in order to ensure the smooth movement of the variable diameter cam channel and the connecting column, it is often necessary to increase the fit clearance to avoid jamming. However, an excessively large clearance will cause the connecting column to shake and deviate during operation, frequently hitting the channel wall, resulting in unstable movement and significantly increasing the noise of the device, which seriously affects the user experience. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a massage device to solve the problems of excessive noise and unstable motion structure generated during operation of the existing massage device.

[0006] The massage device provided in this embodiment of the utility model includes:

The rotating shaft is connected to the rotary drive member. The rotating shaft includes a first connecting structure extending in its axial direction. The plurality of sliders are arranged around the rotation axis of the rotating shaft, and each slider is movably disposed in the housing in the radial direction of the rotating shaft. The slider is provided with a second connecting structure connected to the first connecting structure. A plurality of tentacles are arranged around the rotation axis of the rotating shaft. Each tentacle includes a pressure-applying part, a rotating part, and a transmission part. The pressure-applying part is located outside the housing, the transmission part is located inside the housing and connected to the corresponding slider, and the rotating part is located between the pressure-applying part and the transmission part and connected to both the pressure-applying part and the transmission part. In the rotation direction of the rotating shaft, the rotating part is rotatably connected to the housing. The rotary drive is used to drive the shaft to rotate, and the first connecting structure cooperates with several second connecting structures to move several pressure-applying parts toward or away from the center of the housing.

[0008] In one embodiment, the first connecting structure is a plurality of eccentric rotating members arranged sequentially in the axial direction of the rotating shaft, and the second connecting structure is a slot-shaped hole passing through the slider. The plurality of sliders are stacked in the axial direction of the rotating shaft so that the plurality of slot-shaped holes are interconnected to form a transmission channel. The plurality of eccentric rotating members pass through the transmission channel and are disposed in the plurality of sliders, and each eccentric rotating member abuts against the hole wall of each slot-shaped hole.

[0009] In one embodiment, the central axes of the plurality of eccentric rotating members are misaligned with each other.

[0010] In one embodiment, the housing is provided with a mounting base, the rotary drive is mounted on the mounting base, the mounting base is provided with a through-hole, and the end of the rotating shaft away from the rotary drive passes through the through-hole to be rotatably connected to the mounting base. The first connecting structure is located in the mounting base.

[0011] In one embodiment, the mounting base is provided with a plurality of sliding grooves, and the plurality of sliding grooves are arranged in the axial direction of the rotating shaft; The slider includes a rotating seat and a guide seat. In the circumferential direction of the rotating shaft, the rotating seat is rotatably connected to the transmission part and located outside the mounting base. The guide seat is disposed on the side of the rotating seat away from the transmission part. The guide seat of each slider is slidably connected to the corresponding slide groove. The second connecting structure is disposed at the guide seat to cooperate with the first connecting structure.

[0012] In one embodiment, the slide groove is configured as an upper slide groove and a lower slide groove arranged vertically. The upper slide groove extends in a first direction and passes through both sides of the mounting base, and the lower slide groove extends in a second direction and passes through the other two sides of the mounting base. There are four sliders. Two adjacent sliders close to the rotary drive member are arranged opposite to each other in the first direction and are slidably connected to the upper slide groove. The other two adjacent sliders are arranged opposite to each other in the second direction and are slidably connected to the lower slide groove. The first direction is perpendicular to the second direction.

[0013] In one embodiment, the rotating seat includes two separately arranged connecting ears and a fixed shaft. The two ends of the fixed shaft are respectively connected to the two connecting ears. The transmission part is a card holder with a slot. The card holder is located between the two connecting ears, and the fixed shaft is accommodated in the slot.

[0014] In one embodiment, the mounting base includes an upper body and a lower body, the lower body being spaced apart from the upper body, and the lower body being located on the side of the upper body facing away from the rotary drive member; the upper body has two first flanges on the side facing the lower body, the two first flanges being spaced apart from each other and extending in a first direction to jointly enclose the upper sliding groove; the lower body has two second flanges on the side facing the upper body, the two second flanges being spaced apart from each other and extending in a second direction to jointly enclose the lower sliding groove.

[0016] In one embodiment, the guide seat of one of the sliders disposed in the upper slide groove is provided with a step, the step being used to accommodate the guide seat of the other slider, so that the rotating seats of the two sliders disposed opposite to each other are symmetrically arranged in the first direction.

[0017] Compared with the prior art, the beneficial effects of the massage device provided in this utility model embodiment are that the massage device can not only simulate human hand massage, but also has low noise and better movement stability during operation.

[0018] Specifically, the rotary drive is used to drive the rotating shaft to rotate. Then, the first connecting structure on the rotating shaft can cooperate with the second connecting structure. The rotation of the rotating shaft can be converted into linear movement of each slider in its specific radial direction. When each slider is displaced, it can drive the corresponding tentacle to move because it is connected to the transmission part of the tentacle. The movement of the transmission part is restricted by the rotating part, which ultimately causes the pressure part to move away from or closer to the center of the shell. The coordinated movement of each pressure part simulates the effect of human hand massage. Furthermore, by setting the rotating shaft and slider, when the rotating shaft cooperates with the second connecting structure of the slider using the first connecting structure, the cooperation gap between the two is small, which can effectively reduce the slider's deviation and wobbling. This results in less noise during operation and significantly improved motion stability, leading to a better user experience. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] This utility model embodiment provides a massage device 1000, such as... Figure 1 - Figure 5 , Figure 8 as well as Figure 9 As shown, the massage device 1000 includes a housing 10, a rotary drive 20, a transmission assembly 30, and a plurality of tentacles 40. The rotary drive 20 is installed inside the housing 10. The transmission assembly 30 includes a rotating shaft 31 and a plurality of sliders 32. The rotating shaft 31 is connected to the rotary drive 20 and includes a first connecting structure 311 extending axially therefrom. The plurality of sliders 32 are arranged around the rotation axis of the rotating shaft 31, and each slider 32 is movably disposed in the housing 10 radially therefrom. The sliders 32 are provided with a second connecting structure 321 connected to the first connecting structure 311. The plurality of tentacles 40 rotate around the rotating shaft 31. The shaft 31 is aligned along the axis. The hand 40 includes a pressure-applying part 41, a rotating part 42, and a transmission part 43. The pressure-applying part 41 is located outside the housing 10, the transmission part 43 is located inside the housing 10 and connected to a corresponding slider 32, and the rotating part 42 is located between the pressure-applying part 41 and the transmission part 43, and is connected to both the pressure-applying part 41 and the transmission part 43. In the rotation direction of the shaft 31, the rotating part 42 is rotatably connected to the housing 10. A rotary drive 20 drives the shaft 31 to rotate. A first connecting structure 311 cooperates with several second connecting structures 321 to move the pressure-applying parts 41 towards or away from the center of the housing 10. This application solves the problem of excessive noise generated by the existing massage device 1000 in simulating human hand massage. This massage device 1000 not only simulates human hand massage but also operates with low noise and better motion stability.

[0023] Specifically, the rotary drive 20 drives the rotating shaft 31 to rotate. Then, the first connecting structure 311 on the rotating shaft 31 can cooperate with the second connecting structure 321. The rotation of the rotating shaft 31 can be converted into linear movement of each slider 32 in its own specific radial direction. When each slider 32 is displaced, it can drive the corresponding tentacle 40 to move because it is connected to the transmission part 43 of the tentacle 40. The movement of the transmission part 43 is restricted by the rotating part 42, which ultimately causes the pressure part 41 to move away from or closer to the center of the housing 10. The joint movement of each pressure part 41 simulates the effect of human hand massage. Furthermore, by setting the rotating shaft 31 and the slider 32, when the rotating shaft 31 cooperates with the second connecting structure 321 of the slider 32, the cooperation gap between the two is small, which can effectively reduce the deviation and wobbling of the slider 32, thereby reducing the noise generated during operation and significantly improving the motion stability, resulting in a better user experience.

[0024] Preferably, in this application, the rotary drive 20 can be a DC motor. The cost of a DC motor of the same power is lower than that of a servo motor or a stepper motor, and it does not require a complex control circuit system, making the setup simpler and more reasonable.

[0025] Reference Figure 3 and Figure 5 In one embodiment, the first connecting structure 311 is a plurality of eccentric rotating members 3111 arranged sequentially in the axial direction of the rotating shaft 31, and the second connecting structure 321 is a slotted hole 3211 passing through the slider 32. The plurality of sliders 32 are stacked in the axial direction of the rotating shaft 31 so that the plurality of slotted holes 3211 are interconnected to form a transmission channel. The plurality of eccentric rotating members 3111 pass through the transmission channel and pass through the plurality of sliders 32, and each eccentric rotating member 3111 abuts against the hole wall of each slotted hole 3211. With this configuration, the central axis of the eccentric rotating component 3111 and the axis of the rotating shaft 31 are spaced apart radially on the rotating shaft 31. When each eccentric rotating component 3111 rotates, it can change its relative position in the corresponding slotted hole 3211 and abut against the hole wall of the corresponding slotted hole 3211 when changing its position, thereby applying pressure to the corresponding slider 32 and ultimately forming a linear movement of the slider 32 in its respective specific radial direction. This realizes the transformation of the rotation of the rotating shaft 31 into the linear movement of the slider 32. During the operation, the eccentric rotating component 3111 and the hole wall of the slotted hole 3211 always abut against each other. The fit gap between the two is small, the movement of the slider 32 is more stable, and the noise generated is reduced.

[0026] In the above embodiments, there are many ways to set the slotted hole 3211. It can be a straight slot or an elliptical hole. There is no limitation on its setting method here.

[0027] There are many ways to set the eccentric rotating component 3111. For example, in this application, the eccentric rotating component 3111 is circular. The circular eccentric rotating component 3111 can move better in the slotted hole 3211 and cooperate with the hole wall of the slotted hole 3211, so as to drive the slider 32 to move more smoothly and effectively reduce the occurrence of jamming.

[0028] In one embodiment, the central axes of several eccentric rotating members 3111 are misaligned. This arrangement allows each slider 32 to open outward or retract inward synchronously, better simulating the massage effect of a human hand grasping and kneading.

[0029] Specifically, a number of eccentric rotating parts 3111 overlap in the axial direction of the rotating shaft 31, and the number of eccentric rotating parts 3111 are arranged at equal intervals around the circumference of the rotating shaft 31.

[0030] It is worth mentioning that by implementing the above embodiments, the rotary drive 20 can convert the linear reciprocating movement of each slider 32 in its specific radial direction through a single continuous rotation, thereby enabling the synchronous opening or retraction of each tentacle 40. The rotary drive 20 can simulate human hand massage with several tentacles 40 without reversing direction. The unidirectional rotation setting avoids the inertial impact during reverse start-up, reduces frictional loss between the rotating shaft 31 and the slider 32, and avoids motion jamming caused by frequent reversals, making the massage device 1000 perform more smoothly when massaging the user, resulting in a better user experience. In addition, unidirectional continuous rotation usually does not require positional accuracy, and the control system of the massage device 1000 can eliminate feedback components such as encoders and Hall sensors, resulting in lower costs.

[0031] Reference Figure 3 and Figure 6 In one embodiment, a mounting base 11 is provided inside the housing 10, and a rotary drive 20 is mounted on the mounting base 11. The mounting base 11 has a through-hole 111, and one end of the rotating shaft 31 away from the rotary drive 20 passes through the through-hole 111 to be rotatably connected to the mounting base 11. A first connecting structure 311 is located in the mounting base 11. With this configuration, the other end of the rotating shaft 31 is rotatably connected to the mounting base 11. Due to the support and limiting effect of the mounting base 11, the rotating shaft 31 has better stability during rotation. Even at high speeds, the rotating shaft 31 can always maintain axial rotation, preventing the rotating shaft 31 from wobbling. This further enhances the stability of the rotating shaft 31 when it cooperates with the slider 32, and further reduces noise generation.

[0032] Reference Figure 6 and Figure 7 In one embodiment, the mounting base 11 is provided with a plurality of sliding grooves 112, which are arranged in the axial direction of the rotating shaft 31; the slider 32 includes a rotating seat 322 and a guide seat 323. In the circumferential direction of the rotating shaft 31, the rotating seat 322 is rotatably connected to the transmission part 43 and located outside the mounting base 11, and the guide seat 323 is located on the side of the rotating seat 322 away from the transmission part 43. The guide seat 323 of each slider 32 is slidably connected to the corresponding sliding groove 112. The second connecting structure 321 is provided at the guide seat 323 to cooperate with the first connecting structure 311. With this configuration, the slide 112 can guide the slider 32, so that each slider 32 can always move back and forth in a straight line along its own direction of movement, ensuring the stability of the slider 32's movement. Furthermore, the rotating shaft 31, slider 32, and rotary drive component 20 are all mounted on the mounting base 11. Under the same mounting reference of the mounting base 11, the relative positional relationship between the three after assembly can be effectively guaranteed, making the interaction and linkage process between the three more smooth and stable.

[0033] In one embodiment, the slide groove 112 is configured as an upper slide groove 1112 and a lower slide groove 2112 arranged vertically, the upper slide groove 1112 being in a first direction (e.g., Figure 6 As shown in the X direction, the groove 2112 extends along and passes through both sides of the mounting base 11 in the second direction. Figure 6 The slider 32 extends along the Y-direction and passes through the other two sides of the mounting base 11; four sliders 32 are arranged, with two adjacent sliders 32 close to the rotary drive 20 and facing away from each other in the first direction, and both slidingly connected to the upper slide groove 1112; the other two adjacent sliders 32 are facing away from each other in the second direction and both slidingly connected to the lower slide groove 2112; wherein, the first direction is perpendicular to the second direction. With this arrangement, four sliders 32 are arranged, each slider 32 is connected to a tentacle 40, and the pressure parts 41 of the four tentacles 40 together enclose the massage space 44. By reasonably controlling the number of sliders 32, the massage effect is effectively guaranteed, and the number of parts is kept within a suitable range, resulting in a more reasonable design and easier cost control. Furthermore, two adjacent sliders 32 are slidably connected to the upper slide groove 1112 and positioned opposite each other, while two other adjacent sliders 32 are slidably connected to the lower slide groove 2112 and positioned opposite each other. When the rotating shaft 31 rotates, the two sliders 32 at the upper slide groove 1112 can move synchronously towards or away from each other in the first direction, while the other two sliders 32 at the lower slide groove 2112 can move synchronously towards or away from each other in the second direction. Due to the separation of the upper slide groove 1112 and the lower slide groove 2112, the two sets of sliders 32 do not interfere with each other in the movement space, thus making the entire movement process of each tentacle 40 more synchronized and coherent during the cooperation process, and more realistically reproducing human hand massage. Moreover, the coordination of movement can be guaranteed by setting only two slide grooves 112. Compared with the embodiment in which each slider 32 uses an independent slide groove 112, only two slide grooves 112 are needed to cover the movement needs of four tentacles 40, avoiding the redundant structure caused by the superposition of multiple slide grooves 112. It should be noted that the first direction and the second direction are both specific radial directions of the rotating shaft 31.

[0034] It should be noted that the massage space 44 is used to accommodate the massage area so as to better massage the massage area. For example, the user can place the massage area such as the knee, elbow or hand in the massage space 44. When the massage device 1000 is working, several tentacles 40 will apply pressure to the massage area to achieve the effect of simulating human hand massage.

[0035] It is understandable that the number of sliders 32 and corresponding tentacles 40 can be adjusted according to needs, and is not limited here. For example, the number of sliders 32 and tentacles 40 can also be set to 3, with the 3 tentacles 40 together enclosing the massage space.

[0036] Reference Figure 4In one embodiment, the rotating base 322 includes two separately arranged connecting ears 3221 and a fixed shaft (not shown in the figure). The two ends of the fixed shaft are respectively connected to the two connecting ears 3221. The transmission part 43 is a retainer 431, which has a slot 4311 located between the two connecting ears 3221. The fixed shaft is housed in the slot 4311. With this arrangement, the fixed shaft and the slot 4311 cooperate, so that the movement of the rotating base 322 can drive the retainer 431 to move accordingly. The connection between the fixed shaft and the slot 4311 makes the movement of the tentacle 40 smoother, reduces jamming, and further reduces noise generation. Moreover, when assembling the rotating base 322 and the transmission part 43, the connection between the two can be achieved simply by placing the fixed shaft directly into the slot 4311, making the assembly more convenient and quick.

[0037] It should be noted that by using the rotating seat 322 to be rotatably connected to the transmission part 43, when the slider 32 moves back and forth in a linear motion, the rotating seat 322 can better drive the transmission part 43 to move, and ultimately make the pressure part 41 of the contact 40 swing outward or inward, reducing the sticking of the contact 40 during the engagement process and keeping the movement process continuous.

[0038] Reference Figure 6 In one embodiment, the mounting base 11 includes an upper base 113 and a lower base 114, which are spaced apart from the upper base 113 and are located on the side of the upper base 113 facing away from the rotary drive member 20. The upper base 113 has two first flanges 1131 on the side facing the lower base 114. The two first flanges 1131 are spaced apart from each other and extend in a first direction to jointly enclose the upper sliding groove 1112. The lower base 114 has two second flanges 1141 on the side facing the upper base 113. The two second flanges 1141 are spaced apart from each other and extend in a second direction to jointly enclose the lower sliding groove 2112. Two first flanges 1131 together define the upper slide groove 1112, and the guide seats 323 of the two sliders 32 are stacked in the upper slide groove 1112. The second flange 1141 together define the lower slide groove 2112, and the guide seats 323 of the other two sliders 32 are stacked in the lower slide groove 2112. By setting the upper slide groove 1112 and the lower slide groove 2112 at the upper seat body 113 and the lower seat body 114 respectively, the processing and manufacturing difficulty can be reduced. At the same time, the upper slide groove 1112 and the lower slide groove 2112 have a good guiding effect on the sliders 32, and the structural design is also simpler.

[0039] In one embodiment, the lower seat 114 is detachably connected to the upper seat 113. Thus, during assembly, each slider 32 can be first installed on the lower seat 114 and the upper seat 113 respectively, and then the lower seat 114 with the sliders 32 installed can be installed on the upper seat 113, which makes it easier for the assembler to adjust the relative position of each slider 32 and makes the assembly more convenient.

[0040] Reference Figure 6 In one embodiment, a blocking block 312 is also provided on the rotating shaft 31. The blocking block 312 is disposed on the side of the first connecting structure 311 near the rotary drive member 20. The blocking block 312 is accommodated in the through-hole 111 to press against the adjacent slider 32. With this arrangement, the blocking block 312 can limit the adjacent slider 32 in the axial direction of the rotating shaft 31 and act on the other sliders 32, so that each slider 32 can maintain a relative position at the mounting seat 11, reducing the axial upward movement of each slider 32 during movement, making the movement more stable, and further reducing the generation of noise.

[0041] Reference Figure 7 In one embodiment, the guide seat 323 of one of the sliders 32 disposed in the upper slide groove 1112 is provided with a step 3231. The step 3231 is used to accommodate the guide seat 323 of the other slider 32, so that the rotating seats 322 of the two sliders 32 disposed opposite to each other are symmetrically arranged in the first direction. In this way, the step 3231 of the guide seat 323 of one slider 32 can be used to accommodate the guide seat 323 of the other slider 32, thereby effectively reducing the axial depth of the upper slide groove 1112, making the overall structural layout more compact. Furthermore, by providing the step 3231, the rotating seats 322 of the two sliders 32 disposed opposite to each other can be symmetrically distributed on both sides of the upper slide groove 1112, thereby enabling the corresponding two tentacles 40 to be symmetrically distributed, so as to better maintain the coordination of their movements during massage.

[0042] Reference Figure 4 In one embodiment, the housing 10 includes an outer cover plate 12 and an inner cover plate 13. A plurality of tentacles 40 are respectively disposed on the outer cover plate 12 and the inner cover plate 13, such that the outer cover plate 12 and the inner cover plate 13 are located between the pressure application part 41 and the rotating disk, and the inner cover plate 13 is located on the side of the outer cover plate 12 away from the pressure application part 41. The outer cover plate 12 and the inner cover plate 13 together form a plurality of rotating structures, and the outer cover plate 12 is detachably connected to the inner cover plate 13. In this way, the outer cover plate 12 is separated from the inner cover plate 13, and a number of tentacles 40 are inserted through the outer cover plate 12. The rotating part 42 of each tentacles 40 can be placed into the corresponding position. Then, the inner cover plate 13 is fastened to the outer cover plate 12. When the outer cover plate 12 and the inner cover plate 13 are connected, the inner cover plate 13 can cooperate with the corresponding outer cover plate 12 to limit the installation of the rotating part 42 of each tentacles 40. The assembly method is more efficient and convenient. It can also effectively protect the tentacles 40 from damage during the installation process and ensure the stability of the overall structure of the massage device 1000.

[0043] There are various ways to detach the outer cover plate 12 from the inner cover plate 13, such as snap-fit ​​connection or threaded connection. No limitation is made here on the method of detachment and connection.

[0044] In one embodiment, the pressure-applying part 41 is made of an elastic material. Thus, the elastic material of the pressure-applying part 41 has a certain deformation capability, allowing the user to change the shape of the pressure-applying part 41 according to the massage area, thereby enabling the pressure-applying part 41 to make more full contact with the human body, facilitating the application of force to the massage area, and improving the massage experience. For example, the pressure-applying part 41 can be made of a soft tube.

[0045] In one embodiment, the pressure part 41, the transmission part 43 and the rotating part 42 are integrally formed to reduce the number of parts and facilitate assembly.

[0046] Reference Figure 2 and Figure 10 In one embodiment, the massage device 1000 further includes a battery 50 and a control circuit board 60. The control circuit board 60 and the battery 50 are mounted on the housing 10. The battery 50 is electrically connected to the control circuit board 60, and the control circuit board 60 is electrically connected to the first vibrator 70 and the rotary drive 20 to control the operation of the first vibrator 70 and the rotary drive 20. In this way, the battery 50 can be charged and stored, eliminating the need for the user to connect a power cord to the massage device 1000 for operation, making it more convenient to use. The control circuit board 60 controls the operation of the first vibrator 70 and the rotary drive 20, allowing the user to select massage functions according to their needs.

[0047] In one embodiment, the massage device 1000 also includes soft silicone (not shown in the figure), which is wrapped around the pressure-applying part 41. Thus, the soft silicone has a certain elasticity and softness. On the one hand, it can reduce the pressure and friction on the skin during massage and improve the comfort during the massage process. On the other hand, it can also improve the feel of the user holding the massage device 1000.

[0048] Preferably, the soft silicone also has protrusions (not shown in the figure), which can squeeze the skin, allowing the user to experience a deeper and more effective massage.

[0049] In one embodiment, the massage device 1000 also includes soft silicone, which is wrapped around the pressure-applying part 41. Thus, the soft silicone has a certain elasticity and softness. On the one hand, it can reduce the pressure and friction on the skin during massage and improve the comfort during the massage process.
