Description

Technical Field

[0001] The utility model relates to the technical field of massage devices, in particular to a massage instrument kneading and hammering synchronous movement. Background Art

[0002] Prolonged sitting at a desk working or looking down at a mobile phone easily causes soreness in the waist and neck. For this reason, various massage instruments for different parts have been designed. The massage movement is the core device of the massage instrument, and the massage movement usually has the functions of kneading and pounding.

[0003] For example, Chinese Patent Application No. CN201720457150.4 discloses a rotary massage movement with pounding, which includes an upper gearbox cover, a lower gearbox cover, an elastic massage head, a pounding massage head, a connecting rod pin shaft and a pounding connecting rod. The upper gearbox cover and the lower gearbox cover are fixedly connected by screws and studs. A pounding shaft and a motor are arranged inside the lower gearbox cover. Eccentric twists are arranged at both ends of the pounding shaft. The pounding shaft is connected to a bearing seat through the eccentric twists via a second bearing. A pounding pin shaft is arranged on the bearing seat. A first bearing and a large pulley are also arranged on the pounding shaft. The pounding shaft is connected to the lower gearbox cover through the first bearing. The large pulley of the pounding shaft and a small pulley arranged on the driving shaft of the motor are connected to each other through a belt. Worms are arranged at both ends of the driving shaft of the motor in a mating connection. The worms are connected to a turbine arranged on the lower gearbox cover. A small straight gear of the turbine is arranged below the turbine. The turbine is in a mating connection with a large straight gear arranged on the lower gearbox cover through the small straight gear of the turbine. An output shaft is connected above the large straight gear. An elastic massage head is connected above the output shaft.

[0004] In the above patent, by arranging a one-way bearing inside the pulley, when the motor rotates clockwise, it has the effect of separate kneading massage. When the motor rotates counterclockwise, it has both the kneading massage effect and the pounding massage effect.

[0005] However, in the above patent, due to the arrangement of the one-way bearing inside the pulley, when the massage movement is in the separate kneading massage function, the running noise is large, and the one-way bearing is prone to wear, resulting in a short service life of the product. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a massage instrument kneading and hammering synchronous movement, which can reduce the noise during the operation of the massage movement, extend the service life of the massage movement, and reduce the production cost of the product.

[0007] The utility model is realized as follows:

[0008] The utility model provides a synchronous movement mechanism of a massage hammer for a massager, which comprises a housing, a motor, a driving component and a kneading component. The motor, the driving component and the kneading component are all arranged in the housing. The motor is connected with the driving component, and the kneading component is connected with the driving component. The movement mechanism further comprises a hammering component, which includes a driving wheel connected with the driving component and a driving shaft rotatably connected with the housing. A bearing is arranged on the outer wall of the driving shaft, and the driving wheel is sleeved on the outer wall of the bearing.

[0009] The driving shaft is connected with a connecting component, which includes a first sleeve and a first spring. The first sleeve is fixed on the outer wall of the driving shaft, and the first spring is sleeved on the outer wall of the first sleeve. One end of the first spring is fixedly connected with the driving wheel.

[0010] The helix direction of the first spring matches the forward rotation direction of the driving wheel, so that when the driving wheel rotates forward, the driving wheel winds the first spring around the first sleeve to drive the driving shaft to rotate forward.

[0011] A limiting component for restricting the reverse rotation of the driving shaft is arranged on the outer wall of the driving shaft. The limiting component includes a second sleeve and a second spring. The second sleeve is fixed on the outer wall of the driving shaft, and the second spring is sleeved on the outer wall of the second sleeve. One end of the second spring is fixedly connected with the housing. The helix direction of the second spring is opposite to that of the first spring, so that when the driving shaft rotates reversely, the second spring winds around the second sleeve to restrict the reverse rotation of the driving shaft.

[0012] Further, the first sleeve and the second sleeve are respectively fixedly connected with the driving shaft through pins.

[0013] Further, a fixing protrusion is arranged on the side wall of the driving wheel, and one end of the first spring is provided with a U-shaped first fixing part, which is fixedly connected with the fixing protrusion.

[0014] Further, a fixing column is arranged on the housing, and one end of the second spring is provided with a U-shaped second fixing part, which is fixedly connected with the fixing column.

[0015] Further, eccentric wheels are respectively connected to both ends of the driving shaft. The eccentric wheels are connected with hammering connecting rods. Two through holes for the hammering connecting rods to pass through the housing are formed in the housing. Guide round tubes are installed in the through holes. The hammering connecting rods are slidably connected with the guide round tubes. The upper ends of the hammering connecting rods are connected with hammering heads.

[0016] Further, the driving wheel is a belt pulley, and the driving component includes a driving belt pulley connected with the output end of the motor and a worm. The driving wheel and the driving belt pulley are connected by a belt.

[0017] The worm is meshed and connected with a worm wheel. The worm wheel is rotatably connected to a rotating shaft. An outer wall of the rotating shaft is connected with a driving gear. The driving gear is meshed and connected with a driven gear. The driven gear is connected with a kneading component to drive the kneading component to move.

[0018] The advantages of the present utility model are as follows: Through the cooperation of two springs and two sets of kits, the driving shaft that drives the hammering component to move rotates following the driving wheel during forward rotation, while during reverse rotation, it is restricted by one of the springs, enabling this massage movement mechanism to have the kneading and hammering functions or only have the kneading function alone. Moreover, compared with the one-way bearing for the springs and kits in this application, the cost of the product is lower and the service life of the product is longer. And during the operation of the single kneading function, since the driving wheel idles on the outer wall of the bearing, the generated noise is smaller. Description of the Drawings

[0029] Please refer to Figures 1 to 7 , the present utility model provides a massage device with a synchronous kneading and hammering mechanism, including a housing 1, a motor 2, a driving component 3 and a kneading component 4. The motor 2, the driving component 3 and the kneading component 4 are all arranged inside the housing 1. The housing 1 is composed of an upper housing 12 and a lower housing 13. After the upper housing 12 and the lower housing 13 are covered, a cavity for accommodating the motor 2, the driving component 3, the kneading component 4 and the hammering component 5 is formed inside the housing 1. The motor 2 is connected to the driving component 3, and the kneading component 4 is connected to the driving component 3. The driving component 3 drives the kneading component 4 to move to achieve the kneading effect. The kneading component 4 and the driving component 3 can adopt the prior art. The mechanism further includes a hammering component 5. The hammering component 5 includes a driving wheel 51 connected to the driving component 3 and a driving shaft 52 rotatably connected to the housing 1. A bearing 53 is arranged on the outer wall of the driving shaft 52. The bearing 53 is a deep groove ball bearing 53. The driving wheel 51 is sleeved on the outer wall of the bearing 53;

[0030] The driving shaft 52 is made of metal. The driving shaft 52 is connected with a connecting component 54. When the driving wheel 51 rotates forward, the connecting component 54 connects the driving shaft 52 and the driving wheel 51, so that the power of the driving wheel 51 can be transmitted to the driving shaft 52 to make the driving shaft 52 rotate forward;

[0031] The connecting component 54 includes a first kit 541 and a first spring 542. The first kit 541 is made of plastic. The first kit 541 is fixed on the outer wall of the driving shaft 52. The first spring 542 is sleeved on the outer wall of the first kit 541. One end of the first spring 542 is fixedly connected to the driving wheel 51, and the other end of the first spring 542 is not fixed; The first spring 542 is a torsion spring.

[0032] In this application, the rotation direction of the driving wheel 51 that can wind the first spring 542 around the first set 541 is defined as the forward rotation, and the rotation direction of the driving wheel 51 that causes the first spring 542 to loosen the winding around the first set 541 is defined as the reverse rotation. The winding direction of the first spring 542 matches the forward rotation direction of the driving wheel 51, so that when the driving wheel 51 rotates forward, the driving wheel 51 winds the first spring 542 around the first set 541 (i.e., the first spring 542 binds the first set 541), increasing the frictional force between the first spring 542 and the first set 541, and connecting the first spring 542 and the first set 541 into one body through the frictional force. Since one end of the first spring 542 is fixedly connected to the driving wheel 51, when the driving wheel 51 rotates forward, the driving wheel 51 drives the drive shaft 52 to rotate forward through the connecting member 54, enabling the massage mechanism core to have the massage effects of both kneading and pounding simultaneously;

[0033] When the driving wheel 51 rotates in the reverse direction, the first spring 542 gradually loosens the winding (binding) around the first set 541, and since a bearing 53 is also provided between the driving wheel 51 and the drive shaft 52. Therefore, when the driving wheel 51 rotates in the reverse direction, the driving wheel 51 idles outside the drive shaft 52, enabling the massage mechanism core to only have the kneading massage effect alone.

[0034] A limiting member 55 for restricting the reverse rotation of the drive shaft 52 is provided on the outer wall of the drive shaft 52. The limiting member 55 includes a second set 551 and a second spring 552. The second spring 552 is a torsion spring, the material of the second set 551 is plastic, the second set 551 is fixed on the outer wall of the drive shaft 52, the second spring 552 is sleeved on the outer wall of the second set 551, one end of the second spring 552 is fixedly connected to the housing 1, the other end of the second spring 552 is not fixed, and the winding direction of the second spring 552 is opposite to that of the first spring 542, so that when the drive shaft 52 rotates in the reverse direction, the second spring 552 winds around the second set 551 to restrict the reverse rotation of the drive shaft 52.

[0035] The winding direction of the second spring 552 is opposite to that of the first spring 542 (for example, if the winding direction of the first spring 542 is right-handed, then the winding direction of the second spring 552 is left-handed). Therefore, when the driving wheel 51 rotates in the reverse direction, the first spring 542 gradually loosens the winding around the first set 541. When the first spring 542 has not completely loosened the winding around the first set 541, the drive shaft 52 can still rotate, and as the drive shaft 52 rotates, the second spring 552 gradually winds to restrict the reverse rotation of the drive shaft 52.

[0036] Specifically, the first set 541 and the second set 551 are respectively fixedly connected to the drive shaft 52 through pins 56.

[0037] Specifically, a fixing protrusion 511 is provided on the side wall of the driving wheel 51. One end of the first spring 542 is provided with a U-shaped first fixing portion 5421, and the first fixing portion 5421 is fixedly connected to the fixing protrusion 511. The first fixing portion 5421 and the fixing protrusion 511 are fixedly connected by bolts and gaskets. One end of the bolt passes through the gasket and is screwed to the fixing protrusion 511, and the gasket contacts the first fixing portion 5421. After the bolt is tightened, the gasket presses the first fixing portion 5421, so that one end of the first spring 542 is fixedly connected to the first fixing portion 5421, as Figure 7 shown.

[0038] Specifically, the housing 1 is provided with a fixing column 11. One end of the second spring 552 is provided with a U-shaped second fixing portion 5521, and the second fixing portion 5521 is fixedly connected to the fixing column 11. The second fixing portion 5521 and the fixing column 11 are fixedly connected by another set of bolts and gaskets. One end of the bolt passes through the gasket and is screwed to the fixing column 11, and the gasket contacts the second fixing portion 5521. After the bolt is tightened, the gasket presses the second fixing portion 5521, so that one end of the second spring 552 is fixedly connected to the second fixing portion 5521.

[0039] Specifically, eccentric wheels 6 are respectively connected to both ends of the driving shaft 52. The eccentric wheels 6 are connected to hammering connecting rods 7. Another bearing 61 is connected between the eccentric wheels 6 and the hammering connecting rods 7. Two through holes 14 for the hammering connecting rods 7 to pass through the housing 1 are formed on the housing 1. The through holes 14 are formed on the upper housing 12. Guide round tubes 8 are installed in the through holes 14. The hammering connecting rods 7 are slidably connected to the guide round tubes 8. The upper ends of the hammering connecting rods 7 are connected to hammer heads 9. When the driving wheel 51 rotates forward, the driving shaft 52 drives the eccentric wheels 6 to rotate, so that the hammering connecting rods 7 reciprocate up and down along the guide round tubes 8, so that the hammer heads 9 can achieve the effect of hammering.

[0040] Specifically, the driving wheel 51 is a belt pulley. The driving assembly includes a driving belt pulley 31 and a worm 32 connected to the output end of the motor 2. The driving wheel 51 and the driving belt pulley 31 are connected by a belt (not shown in the figure); the worm 32 is meshed with a worm gear 33. The worm gear 33 is rotatably connected to a rotating shaft 34. An active gear 35 is connected to the outer wall of the rotating shaft 34. The active gear 35 is meshed with a driven gear 36. The driven gear 36 is connected to the kneading member 4 to drive the kneading member 4 to move.

[0041] A specific application of the present application is:

[0042] When the massage core is simultaneously provided with the kneading and hammering functions:

[0043] The motor 2 rotates, driving the driving pulley 31 to rotate, and causing the driving wheel 51 to rotate forward. When the driving wheel 51 rotates forward, since the helix direction of the first spring 542 matches the forward rotation direction of the driving wheel 51, the first spring 542 will tightly wind around the outer wall of the first set 541, resulting in an increase in the frictional force between the first spring 542 and the first set 541, thereby causing the drive shaft 52 to rotate forward following the driving wheel 51. When the driving wheel 51 rotates forward, since the helix direction of the second spring 552 is opposite to that of the first spring 542, therefore, the forward rotation of the drive shaft 52 will cause the second spring 552 to loosen, so that the limiting member 55 does not impede the forward rotation of the drive shaft 52.

[0044] The forward rotation of the drive shaft 52 drives the eccentric wheel 6 to rotate, causing the hammering connecting rod 7 to reciprocate, so that the hammer head 9 provided at the end of the hammering connecting rod 7 achieves the effect of hammering and knocking.

[0045] When the motor 2 rotates, it also drives the worm 32, and drives the kneading member 4 to rotate through the worm wheel 33, the driving gear 35 and the driven gear 36 to achieve the kneading effect.

[0046] When the massage mechanism only has the kneading function alone:

[0047] The motor 2 rotates in the reverse direction, thereby causing the driving wheel 51 to rotate in the reverse direction. At this time, the first spring 542 gradually loosens its winding around the first set 541. When the first spring 542 has not completely loosened its winding around the first set 541, the drive shaft 52 can still rotate. As the drive shaft 52 rotates, the second spring 552 gradually winds around the second set 551, increasing the frictional force between the second spring 552 and the second set 551 to limit the reverse rotation of the drive shaft 52. When the first spring 542 completely loosens its winding around the first set 541, the driving wheel 51 idles outside the drive shaft 52, and the first spring 542 rotates outside the first set 541 as the driving wheel 51 rotates.

[0048] In this application, the first spring 542 loosening its winding around the first set 541 means that the first spring 542 does not exert a force on the first set 541 to follow the rotation of the driving wheel 51. The second spring 552 loosening its winding around the second set 551 means that the second spring 552 does not exert a force on the second set 551 to limit the reverse rotation of the drive shaft 52. The first spring 542 itself still has a spiral structure sleeved on the outer wall of the first set 541, and the second spring 552 itself still has a spiral structure sleeved on the outer wall of the second set 551.

[0049] Through the cooperation of two springs and two sets of kits, the drive shaft that drives the hammering component rotates following the drive wheel during forward rotation, while during reverse rotation, it is restricted by one of the springs, enabling this massage movement mechanism to have the kneading and hammering functions or only the kneading function. Moreover, compared with the one-way bearing, the springs and kits in this application have lower product costs and longer service lives. And during the operation of the separate kneading function, since the drive wheel rotates idly on the outer wall of the bearing, the generated noise is smaller.

[0050] Although the specific embodiments of the present invention have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should all be covered by the scope protected by the claims of the present invention.
