Description

Technical Field

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

[0002] Current lumbar massage devices generally employ a fixed-spaced arrangement of massage heads, which presents significant limitations in application. Due to individual differences in the curves and muscle thickness of the lower back, rigid massage heads cannot adaptively adjust to the user's body shape. This results in slender users experiencing localized pressure pain, while overweight users struggle to reach deeper muscle tissue, severely impacting massage comfort and therapeutic effectiveness. This structural defect not only forces users to frequently adjust their posture to match the mechanical trajectory, causing additional fatigue, but may also lead to soft tissue damage or impaired blood circulation due to continuous pressure, exacerbating user discomfort. Utility Model Content

[0003] The main purpose of this invention is to propose a massager that aims to solve the problem that the massage head of existing waist massagers cannot adaptively adjust according to the user's body shape.

[0004] To achieve the above objectives, the massager proposed in this utility model includes:

[0005] Supporting entity;

[0006] A massage mechanism includes at least two mechanisms and at least two massage heads. The two mechanisms are spaced apart from each other on the support body, and the two massage heads are located on the same side of the support body and are respectively driven and connected to the two mechanisms. The mechanisms are used to drive the massage heads to move.

[0007] An adjustment mechanism is provided on the support body. The adjustment mechanism includes a drive component and a transmission component. The drive component is driven to at least one of the movement components through the transmission component.

[0008] In one embodiment, the transmission member is provided with at least one transmission part, and at least one of the movement mechanisms is provided with a mating part that is connected to the transmission part in a transmission manner. The transmission member drives the movement mechanism to move through the mating part.

[0009] In one embodiment, the transmission component includes a lead screw, the transmission part is an external thread provided on the lead screw, the mating part is an internal thread provided on the movement, the transmission part is threadedly connected to the mating part, and the lead screw rotates to drive the movement to move along the axial direction of the lead screw.

[0010] In one embodiment, the lead screw is provided with two transmission parts, the external threads of the two transmission parts have opposite helical directions, the mating parts of the two mechanisms are respectively threadedly connected to the two transmission parts, and the lead screw is used to rotate to drive the two mechanisms to move in opposite directions along the axis of the lead screw.

[0013] In one embodiment, the second drive gear includes a bevel gear portion and a straight gear portion. The second drive gear is disposed below the transmission member. The rotating gearbox meshes with the straight gear portion. The first drive gear is arranged perpendicular to the axial direction of the second drive gear and meshes with the bevel gear portion.

[0014] And / or, the drive assembly is located between the two mechanisms.

[0015] In one embodiment, the massager further includes a control mechanism, and the adjustment mechanism further includes a magnet and a Hall element. The magnet is provided on one of the support body and the mechanism, and the Hall element is provided on the other. The Hall element is used to detect the magnetic field of the magnet and send the detection information to the control mechanism.

[0016] And / or, the support body includes a support plate, the adjustment mechanism and the two mechanisms are located on the same side of the support plate;

[0017] And / or, the adjusting mechanism further includes a support rod, which is spaced apart from the transmission member and extends in the same direction, and the movement is slidably mounted on the support rod.

[0018] In one embodiment, the mechanism includes a mounting base, a motor, and an output shaft. The motor is mounted on the mounting base and drivenly connected to the output shaft. The end of the output shaft away from the motor is drivenly connected to the massage head.

The first double gear meshes with the worm gear and the second double gear respectively. The second double gear also meshes with the output gear.

[0020] The technical solution of this utility model involves setting an adjustment mechanism on the support body to drive the movement of the massage cores, thereby adjusting the distance between the massage heads of the massager. Specifically, the massager includes a support body, a massage mechanism, and an adjustment mechanism. The massage mechanism includes at least two massage cores and at least two massage heads. The two massage cores are both located on the support body and spaced apart from each other. The two massage heads are located on the same side of the support body and are each driven and connected to one of the massage cores. The massage cores drive the massage heads to move for waist massage. The adjustment mechanism includes a drive component and a transmission component mounted on the support body. The drive component is driven and connected to at least one of the massage cores via the transmission component, causing one massage core to move closer to or further away from the other, thereby adjusting the distance between the two massage heads. As can be seen, by setting an adjustment mechanism, the distance between the two massage heads is adjustable, allowing the massager to adapt to the back curves of different people, improving its compatibility and thus enhancing massage comfort.

[0034] This utility model proposes a massager 100.

[0035] Please see Figures 1 to 3 In one embodiment of this utility model, the massager 100 includes a support body 1, a massage mechanism 2, and an adjustment mechanism 3. The massage mechanism 2 includes at least two actuators 21 and at least two massage heads 22. The two actuators 21 are both mounted on the support body 1 and spaced apart from each other. The two massage heads 22 are located on the same side of the support body 1 and are connected to the two actuators 21 in a one-to-one driving connection. The actuators 21 drive the massage heads 22 to move for waist massage. The adjustment mechanism 3 includes a drive assembly 31 and a transmission component 32 mounted on the support body 1. The drive assembly 31 is connected to at least one actuator 21 via the transmission component 32, causing one actuator 21 to move closer to or further away from the other actuator 21, thereby adjusting the distance between the two massage heads 22. As can be seen, by setting the adjustment mechanism 3, the distance between the actuators 21 and the massage heads 22 is adjustable, allowing the massager 100 to adapt to the back curves of different people, improving its compatibility and massage comfort.

[0036] It should be noted that existing waist massagers 100 on the market typically have two fixed massage heads 22, the spacing of which cannot be adjusted, resulting in poor adaptability. In this design, the number of massage heads 22 is set to at least two; that is, the number of massage heads 22 can be 2, 4, 6, or other numbers. Each massage head 22 requires a separate driving mechanism 21, therefore the number of mechanisms 21 is the same as the number of massage heads 22, and the specific number is not limited here. This design mainly uses an implementation with two massage heads 22 as an example for illustration.

[0037] Furthermore, at least one of the two mechanisms 21 is movably mounted on the support body 1, meaning one mechanism 21 is movable while the other mechanism 21 is fixed in position. The drive assembly 31 is driven by the movable mechanism 21 via the transmission member 32. Alternatively, the other mechanism 21 is also movably mounted on the support body 1, and the drive assembly 31 is driven by both mechanisms 21 via the transmission member 32, thereby moving the two mechanisms 21 towards or away from each other. Any of the above driving methods can be selected, as long as the distance between the two massage heads 22 can be adjusted.

[0038] The supporting body 1 can be configured as a shell, plate, base, bracket, or other component with a supporting structure. Its design can be tailored to the driving method of the mechanism 21 and the adjustment mechanism 3, and no specific limitations are imposed here. Furthermore, the drive assembly 31 and transmission component 32 can be implemented in various ways. For example, the drive assembly 31 can be a motor 214, a hydraulic pump, a pneumatic pump, or other components, while the transmission component 32 can be a lead screw 321, belt, gear, chain, connecting rod, or other components, which can be selected according to actual needs.

[0039] In one embodiment, the transmission member 32 is provided with at least one transmission part 322, and at least one movement 21 is provided with a mating part 211 that is connected to the transmission part 322 in a transmission manner. The transmission member 32 drives the movement 21 through the mating part 211.

[0040] like Figure 3 and Figure 5 As shown, in one embodiment of this utility model, the transmission member 32 is provided with at least one transmission part 322, and the movement 21 is provided with at least one mating part 211. The transmission member 32 applies force to the mating part 211 through the transmission part 322 to drive the movement 211 to move. For example, the transmission part 322 is commonly set as a gear, and the mating part 211 is set as a rack. The movement 21 can be driven by the gear and rack. Alternatively, a chain and sprocket structure can be used. Power can be transmitted by the meshing of the chain and sprocket. Or, a hydraulic / pneumatic linkage transmission can be used. The linkage is pushed by the hydraulic pump / pneumatic pump and the force is applied to the movement 21, which can also achieve the transmission effect. Therefore, the specific structure of the transmission part 322 and the mating part 211 is not limited here.

[0041] It should be noted that multiple transmission parts 322 can be provided on the transmission component 32, and each transmission part 322 corresponds to a mating part 211 of the mechanism 21. When the drive assembly 31 drives the transmission component 32 to move, multiple transmission parts 322 can simultaneously drive multiple mechanisms 21 to move. It can be understood that providing multiple transmission parts 322 on a single transmission component 32 can reduce the structural complexity of the adjustment mechanism 3 and reduce assembly and production difficulties. In this scheme, the lead screw 321 is mainly used to transmit force, and the specific details will be described below.

[0042] In one embodiment, the transmission member 32 includes a lead screw 321, a transmission part 322 is an external thread provided on the lead screw 321, and a mating part 211 is an internal thread provided on the movement 21. The transmission part 322 is threadedly connected to the mating part 211, and the lead screw 321 rotates to drive the movement 21 to move along the axial direction of the lead screw 321.

[0043] like Figure 3 and Figure 5 As shown, in one embodiment of this utility model, the transmission component 32 includes a lead screw 321. Specifically, the transmission part 322 is an external thread provided on the lead screw 321 and extending along its axial direction. The mating part 211 of the movement 21 is provided with an internal thread that matches the external thread. The movement 21 is threadedly connected to the transmission part 322 of the lead screw 321 through the mating part 211. The drive assembly 31 drives the transmission component 32 to rotate around its axial direction, which can drive the movement 21 to move along the axial direction of the lead screw 321.

[0044] Understandably, when a user uses the massager 100 to massage their waist, they usually lie on the massager 100. The massage head 22 and the mechanism 21 need to withstand a certain amount of pressure. The lead screw 321 can provide high force transmission efficiency, preventing jamming when the drive component 31 pushes the mechanism 21 to move. In addition, the self-locking property of the lead screw 321 can effectively prevent the load from moving in the opposite direction, enhancing the stability of the system. Furthermore, the thread structure of the lead screw 321 has high transmission precision, which can accurately adjust the distance between the two massage heads 22, which is beneficial to improving the user experience.

[0045] In one embodiment, the lead screw 321 is provided with two transmission parts 322, the external threads of the two transmission parts 322 are in opposite directions, the mating parts 211 of the two movement cores 21 are respectively threadedly connected to the two transmission parts 322, and the lead screw 321 is used to rotate to drive the two movement cores 21 to move in opposite directions along the axis of the lead screw 321.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the lead screw 321 is provided with two transmission parts 322. Specifically, the two transmission parts 322 are spaced apart and their external threads have opposite helical directions. The mating parts 211 of the two movement cores 21 are threadedly connected to the two transmission parts 322 respectively. When the drive assembly 31 drives the lead screw 321 to rotate, the two movement cores 21 move simultaneously in opposite directions along the axial direction of the lead screw 321 under the drive of the two transmission parts 322, so that the massage heads 22 on the two movement cores 21 move closer or further apart. It can be understood that by adjusting the movement of the two massage heads 22 simultaneously, the user can adjust the massage heads 22 to the accurate position without adjusting their posture, which is beneficial to improving the practicality of the massager 100.

[0047] In one embodiment, the movement 21 is provided with a bushing 212, and the mating part 211 is an internal thread provided on the bushing 212. The bushing 212 is rotatably sleeved on the lead screw 321 and threadedly connected to the transmission part 322.

[0048] like Figure 5 As shown, in one embodiment of this utility model, a bushing 212 is provided on the mechanism 21. Specifically, the bushing 212 has an internal thread that matches the transmission part 322. The bushing 212 is fixedly installed on the mechanism 21. The lead screw 321 passes through the bushing 212, and the external thread of the transmission part 322 meshes with the internal thread of the bushing 212. When the lead screw 321 rotates around its axis, it can drive the mechanism 21 to move through the bushing 212. It should be noted that the cooperation between the bushing 212 and the lead screw 321 can ensure that the rotation of the lead screw 321 is synchronized with the rotation of the shaft, reducing sliding friction and improving transmission efficiency. Furthermore, the bushing 212 can serve as a support component for the lead screw 321, reducing direct contact between the lead screw 321 and other mechanical parts, thereby reducing friction and wear and extending the service life of the massager 100. In addition, the cooperation between the bushing 212 and the lead screw 321 helps to reduce friction and avoid noise generated by direct metal-to-metal friction, making the massager 100 operate more quietly.

[0049] In one embodiment, the drive assembly 31 includes a rotary gearbox 311, a first drive gear 312, and a second drive gear 313. The first drive gear 312 is disposed on the transmission member 32, and the rotary gearbox 311 is drivenly connected to the first drive gear 312 through the second drive gear 313.

[0050] like Figures 1 to 3 As shown, in one embodiment of this utility model, the drive assembly 31 further includes a rotary gearbox 311, a first drive gear 312, and a second drive gear 313. The first drive gear 312 is mounted on the transmission member 32. The rotary gearbox 311 is drivenly connected to the first drive gear 312 via the second drive gear 313. The rotary gearbox 311 provides power to drive the second drive gear 313 to rotate. The second drive gear 313 meshes with the first drive gear 312. When the second drive gear 313 rotates, it can drive the transmission member 32 to rotate via the first drive gear 312. Using two drive gears can effectively distribute the load in the transmission system, avoid excessive pressure on a single gear, reduce wear or failure caused by overload, and help extend the service life of the massager 100.

[0051] In one embodiment, the second drive gear 313 includes a bevel gear portion 3131 and a straight gear portion 3132. The second drive gear 313 is disposed below the transmission member 32. The rotating gear box 311 meshes with the straight gear portion 3132. The first drive gear 312 and the second drive gear 313 are arranged perpendicularly to each other and mesh with the bevel gear portion 3131.

[0052] And / or, the drive assembly 31 is located between the two mechanisms 21.

[0053] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the second drive gear 313 includes a bevel gear portion 3131 and a spur gear portion 3132. Specifically, the axial direction of the rotating gearbox 311 is parallel to the axial direction of the second drive gear 313, and the rotating gearbox 311 meshes with the spur gear portion 3132 of the second drive gear 313 to drive the second drive gear 313 to rotate around its axial direction. The first drive gear 312 is a bevel gear and is coaxially arranged with the lead screw 321. The axial direction of the lead screw 321 is perpendicular to the axial direction of the second drive gear 313. The second drive gear 313 is located below the lead screw 321, and the bevel gear portion 3131 meshes with the first drive gear 312 to achieve vertical transmission. It can be understood that the vertical transmission structure is beneficial to reducing the height of the massager 100, thereby reducing the overall volume of the massager 100.

[0054] In one embodiment of this utility model, the drive assembly 31 is disposed between the two mechanisms 21. Specifically, there is a space between the two mechanisms 21. Disposing the drive assembly 31 within this space improves the compactness of the massager 100 components and further reduces the overall size of the massager 100. Furthermore, disposing the first drive gear 312 between the two transmission parts 322 balances the forces transmitted to the two mechanisms 21, prevents overload on one end of the lead screw 321, ensures stable operation of the massager 100, and optimizes the mechanical transmission model.

[0055] In one embodiment, the massager 100 further includes a control mechanism, and the adjustment mechanism 3 further includes a magnet 33 and a Hall element 34. A magnet 33 is provided on one of the support body 1 and the mechanism 21, and a Hall element 34 is provided on the other. The Hall element 34 is used to detect the magnetic field of the magnet 33 and send the detection information to the control mechanism.

[0056] And / or, the support body 1 includes a support plate 11, an adjustment mechanism 3, and two mechanisms 21 located on the same side of the support plate 11;

[0057] And / or, the adjustment mechanism 3 also includes a support rod 35, which is spaced apart from the transmission member 32 and extends in the same direction, and the movement 21 is slidably mounted on the support rod 35.

[0058] In one embodiment of this utility model, the massager 100 further includes a control mechanism (not shown), which typically includes a power supply and a main control board, such as... Figure 4As shown, the adjustment mechanism 3 also includes a magnet 33 and a Hall element 34. A magnet 33 is provided on one of the support body 1 and the mechanism 21, and a Hall element 34 is provided on the other. The main control board is electrically connected to the drive assembly 31 and the Hall element 34. The Hall element 34 is used to detect the magnetic field strength of the magnet 33 and transmit the information to the main control board. After the main control board obtains the information, it can calculate the position information of the mechanism 21 and control the drive assembly 31 to move the mechanism 21 according to the information, thereby adjusting the position of the massage head 22.

[0059] In one embodiment of this utility model, the support body 1 includes a support plate 11, an adjustment mechanism 3, and two mechanisms 21 disposed on the same side of the support plate 11. It is understood that by providing the support plate 11, its flat surface simplifies the movement structure of the mechanisms 21 and provides stable support, preventing the massage head 22 and mechanisms 21 from deforming under pressure during use. Furthermore, in another embodiment of this utility model, the support plate 11 has a mounting hole 1a for inserting a magnet 33. The magnet 33 is inserted into the mounting hole 1a from the side of the support plate 11 away from the mechanisms 21. The mechanism 21 has a mounting groove 213a on the side facing the support plate 11, and a Hall element 34 is disposed in the mounting groove 213a for detecting the magnetic field strength of the magnet 33.

[0060] In one embodiment of this utility model, such as Figure 2 As shown, the adjusting mechanism 3 also includes a support rod 35. Specifically, the support rod 35 is a cylindrical rod structure and is arranged parallel to and spaced apart from the lead screw 321. The movement 21 passes through the lead screw 321 and the support rod 35 respectively. When the lead screw 321 rotates and drives the movement 21 to move, the movement 21 can move along the axis of the support rod 35, playing a guiding and supporting role. Furthermore, four support seats 12 are provided on the support plate 11. The four support seats 12 are located at the four corners of the support plate 11. The two ends of the lead screw 321 and the two ends of the support rod 35 are rotatably mounted on the support seats 12. The ends of the lead screw 321 and the ends of the support rod 35 are also provided with bearings 14, and the bearings 14 are limited and installed on the support seats 12 by the first pressure cover 13.

[0061] In one embodiment, the mechanism 21 includes a mounting base 213, a motor 214, and an output shaft 215. The motor 214 is mounted on the mounting base 213 and drivenly connected to the output shaft 215. The end of the output shaft 215 away from the motor 214 is drivenly connected to the massage head 22.

[0062] like Figure 5As shown, in one embodiment of this utility model, the mechanism 21 further includes a mounting base 213, a motor 214, and an output shaft 215. Specifically, the mounting base 213 has two slots on the side away from the support body 1. One slot is used to install a bushing 212, and the other slot is used to install a sleeve 2132. The sleeve 2132 is used to fit on the support rod 35 to reduce sliding friction. The mounting base 213 is provided with two second pressure caps 2131 to fix and limit the sleeve 2132 and the bushing 212 respectively. An installation groove 213a is provided between the two slots. The motor 214 is located in the installation groove 213a and is driven and connected to the output shaft 215. The end of the output shaft 215 away from the motor 214 extends out of the support body 1 and is connected to the massage head 22. The control mechanism can control the motor 214 to drive the output shaft 215 to rotate, so that the massage head 22 rotates around the axis of the output shaft 215 and is used for massage.

[0063] It should be noted that the output shaft 215 can be located at the output end of the motor 214, and the motor 214 can directly drive the output shaft 215 to rotate. However, in order to increase the transmission ratio, a gear set or belt chain mechanism can also be added between the output shaft 215 and the motor 214. The specific configuration can be made according to the requirements.

[0064] In one embodiment, the mechanism 21 further includes a first double gear 216, a second double gear 217, and an output gear 218. The output end of the motor 214 is provided with a worm gear 219. The first double gear 216 is rotatably mounted on the output shaft 215, and the output gear 218 is fixedly connected to the output shaft 215. The second double gear 217 is mounted on the mounting base 213. The first double gear 216 meshes with the worm gear 219 and the second double gear 217 respectively, and the second double gear 217 also meshes with the output gear 218.

[0065] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the mechanism 21 further includes a first double gear 216, a second double gear 217, and an output gear 218. Specifically, the output gear 218 is fixedly mounted on the output shaft 215, the first double gear 216 is rotatably mounted on the output shaft 215, and the output end of the motor 214 is provided with a worm 219. The worm 219 meshes with the large diameter gear ring of the first double gear 216, the small diameter gear ring of the first double gear 216 meshes with the large diameter gear ring of the second double gear 217, and the small diameter gear ring of the second double gear 217 meshes with the output gear 218. The worm 219 transmits force to the output gear 218 through the first double gear 216 and the second double gear 217, and the output gear 218 drives the output shaft 215 to rotate.

[0066] As can be seen from the above, by setting two double gears to increase the transmission ratio, the load on the motor 214 can be reduced, avoiding damage to the equipment caused by the motor 214 operating at full load or even overload, and extending the service life of the equipment. In addition, by using a worm gear 219 to drive the motor 214 laterally on the mounting base 213, the space occupied by the mechanism 21 in terms of height can be reduced, which is beneficial to reducing the size of the massager 100. Furthermore, in order to fix the motor 214 on the mounting base 213, the mechanism 21 also includes a fixing member 2133. The fixing member 2133 has a through hole, through which the upper end of the output shaft 215 passes and connects to the massage head 22. The fixing member 2133 is set on the mounting base 213 to limit the installation of the motor 214, the output gear 218, the first double gear 216 and the second double gear 217.

[0067] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
