Description

Technical Field

[0001] The present invention relates to the technical field of massagers, and particularly to a kneading and pounding massager and its massage mechanism.

Background Art

[0002] In modern social life, people often sit for long hours at the office, study in the classroom for long hours, or sit for long hours in the dormitory or at home playing with the computer or mobile phone. Due to the daily accumulation, many people inevitably suffer from cervical spondylosis and periarthritis of the shoulder joint. There has emerged a shoulder belt type massager that massages the shoulders and neck. The shoulder belt type massager mainly massages the user's shoulders and neck. When in use, the drive device provides mechanical kinetic energy to the massage mechanism, so that the massage mechanism relaxes the user's muscles in a regular rotation, rocking, vibration, pounding and other ways, penetrates through the meridians, improves the blood circulation of the shoulders and neck, and can relieve symptoms such as muscle stiffness and pain in the shoulders and neck.

[0003] Currently, general massagers can be divided into kneading massagers and pounding massagers according to their functions. However, the kneading massagers and pounding massagers in the prior art generally have only a single function, that is, the kneading massager has only the kneading massage function, and the pounding massager has only the pounding massage function, which makes it difficult to meet the user's usage needs. Currently, some massagers can realize the two-in-one function of kneading and pounding, but their structures are more complex, the volume is large, and the cost is high. In addition, the kneading and pounding functions of many massagers can operate independently, but cannot operate simultaneously, so the massage effect is low.

[0004] In view of this, in order to address many defects and inconveniences caused by the insufficient structural design of the conventional massage mechanism, the present invention has advanced deep conceptions, actively carried out research and improvement, and developed prototypes to develop the present invention.

[0020] When the above structure is used, when the massage mechanism of the present invention operates, the motor operates to drive and rotate the first transmission mechanism and the second transmission mechanism. The first transmission mechanism drives the kneading shaft, the eccentric wheel, and the yo-yo wheel to rotate, and further drives the first massage head bracket and the second massage head bracket to rotate. The one-way needle bearing of the second transmission mechanism selects whether to be locked or rotated according to different rotation directions of the motor. When the one-way needle bearing is locked, the second transmission mechanism transmits at the same speed as the first transmission mechanism, so that the first massage head bracket and the second massage head bracket drive the first massage head and the second massage head to perform a synchronous operation for a kneading and pinching massage operation, and the knocking module does not perform a knocking operation. When the one-way needle bearing rotates, by driving and accelerating the transmission of the V-ribbed belt, the knocking rod drives the first massage head bracket and the first massage head to accelerate and swing up and down, and cooperates with the second massage head to perform a pinching and kneading massage operation while performing a knocking operation. The massage mechanism of the present invention can simultaneously drive the first massage head bracket and the second massage head bracket by one motor to swing left and right and up and down, so that the first massage head and the second massage head complete a kneading and pinching operation, and can select whether to perform a kneading and pinching massage and a knocking operation at the same time based on the forward or reverse rotation of the motor. The overall structure is compact, the manufacturing cost is low, and the market competitiveness can be improved.

[0028] The second transmission mechanism 4 includes a V-ribbed belt 41, a one-way needle bearing pulley 42, a one-way needle bearing 43, and a small pulley 44. The one-way needle bearing 43 is provided on the connecting shaft 9 that fixes the knocking gear 34. The one-way needle bearing pulley 42 is fitted into the one-way needle bearing 43.

One of the output shafts 21 is connected to the first transmission mechanism 3, and the other output shaft 21 is connected to the second transmission mechanism 4. Naturally, the corresponding transmission gears need to be corrected correspondingly. The above is only one specific embodiment of the present application.

[0030] As shown in FIG. 17, the kneading module 6 includes an eccentric wheel 61, a yawing wheel 62, a first massage head bracket 63, a second massage head bracket 64, a first massage head 65, and a second massage head 66. The kneading gear 33 is provided at the center of the kneading shaft 5. The kneading modules 6 are symmetrically provided on both sides of the kneading shaft 5. The eccentric wheel 61 is fixedly provided on the kneading shaft 5. The first massage head bracket 63 is fitted on the eccentric wheel 61. The yawing wheel 62 is provided on the kneading shaft 5 outside the eccentric wheel 61 to limit the first massage head bracket 63 to the eccentric wheel 61. The second massage head bracket 64 is fitted on the yawing wheel 62. The outer end of the yawing wheel 62 is limited by a yawing wheel fixing base 67, so that the second massage head bracket 64 is limited to the yawing wheel 62. The yawing wheel 62 between the first massage head bracket 63 and the second massage head bracket 64 forms a yawing inclined surface 621 with one side thin and the other side thick. The first massage head 65 is attached to the tip of the first massage head bracket 63. A gimbal bracket 631 is provided at the base end of the first massage head bracket 63.

A limiting base 15 is provided at a position corresponding to the limiting column 641 of the mechanism case 1. A limiting groove 16 for the limiting column 641 to move is formed in the limiting base 15. The limiting column 641 is movably provided in the limiting groove 16.

[0031] As shown in Fig. 17, the knocking module 8 includes a knocking base 81 and a knocking rod 82. The knocking base 81 is eccentrically provided on both sides of the knocking shaft 7 and at positions corresponding to the first massage head bracket 63. One end of the knocking rod 82 is connected to the knocking base 81, and a gimbal ball head 821 is provided at the other end. The gimbal ball head 821 is rotatably provided on the gimbal bracket 631 at the bottom of the first massage head bracket 63.

[0032] Taking the embodiments shown in Figs. 1 to 17 as examples, the operating principle of the massage mechanism 10 of the present invention will be described.

[0033] When the motor 2 rotates forward, the output shaft 21 of the motor 2 drives the triple gear 31 to rotate. One end of the triple gear 31 drives the kneading shaft 5 to rotate, drives the eccentric wheel 61 and the yawing wheel 62 to rotate, and further drives the first massage head bracket 63 and the second massage head bracket 64 to rotate. The limiting post 641 at the bottom of the second massage head bracket 64 is limited by the limiting groove 16 of the limiting base 15, so that the second massage head 66 on the second massage head bracket 64 yaws within a certain range. The first massage head bracket 63 is limited by the knocking rod 82 connected to the gimbal bracket 631 of the first massage head bracket 63 and the yawing inclined surface 621 of the yawing wheel 62, so that the first massage head 65 on the first massage head bracket 63 can swing when the kneading shaft 5 rotates, and can cooperate with the second massage head 66 on the second massage head bracket 64 to realize the massage effects of kneading and pinching. At the same time, the other end of the triple gear 31 drives the knocking gear 34 and the connecting shaft 9 to rotate. At this time, the one-way needle bearing 43 is locked, the V-ribbed belt 41 rotates normally downward. Since the one-way needle bearing 43 prohibits transmission, the gimbal bracket 631 connected to the knocking rod 82 swings up and down synchronously, and the transmission speeds of the second transmission mechanism 4 and the first transmission mechanism 3 are the same, that is, only the kneading and pinching operations are performed during the forward rotation of the motor 2, and the knocking operation is not performed.

[0034] As shown in FIGS. 5 and 6, when the gimbal bracket 631 swings upward to the highest point, the distance between the first massage head 65 and the second massage head 66 becomes the largest, and the current state is the use open state. As shown in FIGS. 7 and 8, when the gimbal bracket 631 swings downward to the lowest point, the interval between the first massage head 65 and the second massage head 66 becomes the smallest, and the current state is the use closed state (i.e., the clamping state).

[0035] When the motor 2 rotates reversely, the output shaft 21 of the motor 2 drives the triple gear 31 to rotate, one end of the triple gear 31 drives the kneading shaft 5 to rotate, drives the eccentric wheel 61 and the yoking wheel 62 to rotate, and further drives the first massage head bracket 63 and the second massage head bracket 64 to rotate. The limiting post 641 at the bottom of the second massage head bracket 64 is limited by the limiting groove 16 of the limiting base 15, so that the second massage head 66 on the second massage head bracket 64 yokes within a certain range. At the same time, the other end of the triple gear 31 drives the knocking gear 34 and the connecting shaft 9 to rotate. At this time, the one-way needle bearing 43 rotates and operates simultaneously. At this time, the transmission process of the second transmission mechanism 4 is an acceleration process (the brushless is about 2000 revolutions per minute, the speed of kneading and clamping is about 35 revolutions, for kneading and knocking, the kneading is 35 revolutions, and the knocking is about 300 times). Since the knocking rod 82 is connected to the gimbal bracket 631, the knocking rod 82 drives the gimbal brackets 631 on both sides of the kneading shaft 5 to swing up and down under the transmission action of the second transmission mechanism 4, and the speed of the swing is synchronized with the speed of the V-ribbed belt 41, and the speed is accelerated to perform the knocking operation.

[0036] As shown in FIGS. 9 to 12, when the motor 2 rotates in the reverse direction, the speed at which the gimbal bracket 631 of the first massage head bracket 63 swings up and down is synchronized with the transmission speed of the V-ribbed belt 41. However, it is different from the speed of the second massage head bracket 64. Thereby, the first massage head bracket 63 drives the first massage head 65 to perform the opening and clamping operations in the same manner. And due to the accelerated transmission of the V-ribbed belt 41, the first massage head bracket 63 can drive the first massage head 65 to perform the tapping operation simultaneously.

[0037] That is, when the one-way needle bearing 43 is locked, the transmission speeds of the first transmission mechanism 3 and the second transmission mechanism 4 are the same, and the massage speeds of the first massage head bracket 63 and the second massage head bracket 64 are the same. Thereby, the first massage head 65 and the second massage head 66 perform the rubbing and clamping massage operation and do not perform the tapping massage operation. When the one-way needle bearing 43 rotates, the second transmission mechanism 4 accelerates and operates, so that the tapping rod 82 drives the first massage head bracket 63 to accelerate and swing up and down. The massage operation of the massage mechanism 10 is rubbing and clamping and tapping. The rubbing is 35 rotations, and the tapping is about 300 times.

[0038] In this embodiment, four massage head holes 111 through which the first massage head 65 and the second massage head 66 extend are formed in the outer upper case 11 of the mechanism case 1. Buffer covers 112 are respectively provided in the four massage head holes 111, and the first massage head 65 and the second massage head 66 extend out from the buffer covers 112.

[0039] In this embodiment, the first massage head 65 is detachably provided on the first massage head bracket 63. At the end of the first massage head bracket 63, a first insertion post 632 is provided. At the proximal end of the first massage head 65, a first connector 651 corresponding to the first insertion post 632 is provided, so that the first massage head bracket 63 is detachably inserted and connected to the first massage head 65 and integrally fitted. The second massage head 66 is detachably provided on the second massage head bracket 64. At the tip of the second massage head bracket 64, a second insertion post 642 is provided. At the proximal end of the second massage head 66, a second connector 661 corresponding to the second insertion post 642 is provided, so that the second massage head bracket 64 is detachably inserted and connected to the second massage head 66 and integrally fitted. By making the first massage head 65 and the second massage head 66 detachable structures, it is possible to facilitate the installation of the first massage head 65 and the second massage head 66, and also to facilitate the replacement of the massage heads. By designing multiple sets of massage heads and simply replacing the first massage head and the second massage head, the massage mechanism can have different massage effects when performing massage.

[0040] In this embodiment, the gimbal bracket 631 at the bottom of the first massage head bracket 63 has a separate structure and includes a left gimbal bracket 633 and a right gimbal bracket 634 that are directly integrally formed with or fixedly provided on the first massage head bracket 63. The left gimbal bracket 633 and the right gimbal bracket 634 are engaged, and a ball hole 635 for engaging with the gimbal ball head 821 of the knocking rod 82 is formed between the left gimbal bracket 633 and the right gimbal bracket 634. The gimbal ball head 821 is installed in the ball hole 635.

[0041] In this embodiment, the knocking base 81 of the knocking module 8 has a mounting hole 811. The mounting hole 811 is fitted with a bearing 83, and the bearing 83 is fitted with a knocking shaft 7. A connecting base 812 is provided on the knocking base 81. A pivot groove 813 is formed on the connecting base 812, and one end of the knocking rod 82 is rotatably connected thereto. One end of the knocking rod 82 is rotatably attached to the pivot groove 813 by a pivot shaft 814.

[0042] When the massage mechanism of the present invention operates, the motor 2 operates to drive the first transmission mechanism 3 and the second transmission mechanism 4 to rotate. The first transmission mechanism 3 drives the kneading shaft 5, the eccentric wheel 61, and the yawing wheel 62 to rotate, and further drives the first massage head bracket 63 and the second massage head bracket 64 to rotate. The one-way needle bearing 43 of the second transmission mechanism 4 selects whether to be locked or rotate according to different rotation directions of the motor 2. When the one-way needle bearing 43 is locked, the second transmission mechanism 4 transmits at the same speed as the first transmission mechanism 3, so that the first massage head bracket 63 and the second massage head bracket 64 drive the first massage head 65 and the second massage head 66 to perform a synchronous operation for a kneading and pinching massage operation, and the knocking module 8 does not perform a knocking operation. When the one-way needle bearing 43 rotates, by driving and accelerating the transmission of the V-ribbed belt 41, the knocking rod 82 drives the first massage head bracket 63 and the first massage head 65 to accelerate and swing up and down, and cooperates with the second massage head 66 to perform a pinching and kneading massage operation, and at the same time, performs a knocking operation.

[0043] The massage mechanism of the present invention can drive the first massage head bracket 63 and the second massage head bracket 64 simultaneously by one motor 2 to perform yawing in the left - right and up - down directions. Thereby, the first massage head 65 and the second massage head 66 complete the pinching operation, and based on the forward or reverse rotation of the motor 2, it is possible to perform the pinching massage and at the same time select whether to perform the tapping operation. The overall structure is compact, the manufacturing cost is low, and the market competitiveness can be improved.

[0044] The above - mentioned embodiments and drawings do not limit the form and specifications of the products of the present invention, and any appropriate changes or modifications made by those skilled in the art thereto should be regarded as not departing from the patent scope of the present invention.
