Description

Technical Field

[0001] The present invention relates to the field of massage mechanisms, and in particular to a multi-functional massage device and a massage machine. Background Art

[0002] A massager is a health care device developed based on physics, bionics, bioelectrics, etc. Due to its convenient use method and remarkable massage effect, it can be used for self-massage at any time in daily life, and thus is favored by users. Currently, for the massage products with pinching and kneading massage actions on the market, when the pinching and kneading actions reverse, the actions can only be fixed, either pinching and kneading left and right, or swinging left and right fixedly, and the massage method cannot be changed by changing the rotation direction of the motor, nor can multiple actions be switched by a mechanical structure. For example, for a massage machine shown in the patent document CN107307982B, in order to enable the massage component to have a commutation function, an additional clutch mechanism and a pusher need to be provided. Therefore, there is an urgent need for a new massage device on the market, which can achieve multiple action switching by a mechanical structure and can achieve the effect of changing the massage method only by changing the rotation direction of the motor.

[0003] Prior Art: CN107307982B, a massage machine. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a massage device that can change the massage method by changing the rotation direction of the motor.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A multi-functional massage device includes at least a pair of massage arms and a drive assembly for driving the at least a pair of massage arms to swing to perform a massage action, and the pair of massage arms are arranged at intervals from each other; characterized in that the drive assembly includes:

[0007] A rotating shaft configured to rotate around a specified axis; and

[0008] A drive unit configured to be able to change the phase difference between the pair of massage arms by means of the rotation direction of the rotating shaft, so that the pair of massage swing arms can be changed between a first mode and a second mode;

[0009] Wherein, the first mode is configured such that the drive unit drives the pair of massage arms in a manner that the pair of massage arms swing in the same direction on the specified axis; the second mode is configured such that the drive unit drives the pair of massage arms in a manner that the pair of massage arms approach or move away from each other on the specified axis.

[0010] The first mode is scraping massage, and the second mode is pinching and kneading massage.

[0011] In order to enable the massage device to achieve the purpose of kneading massage when rotating forward and swinging massage when rotating reversely, the above-mentioned technical solution is adopted, wherein the left and right massage arms can be relatively rotatably installed in the fixed groove of the driving component, the fixed groove is set to be not perpendicular to the rotation axis, and the massage arm is provided with a rotation limiting protrusion for limiting rotation to prevent the massage arm from rotating with the driving component. Therefore, when the driving component rotates with the rotating shaft, the angle of the fixed groove will change with the rotation. Since the massage arm cannot rotate, its end will swing accordingly to implement massage.

[0012] Furthermore, the driving assembly is rotated by the pin on the rotating shaft. When the rotating direction of the rotating shaft is different, the pin will push two different driving surfaces to drive the driving assembly to rotate. Since there is a guide groove between the driving surfaces, the pin is idle in the guide groove on one side and will not drive the driving assembly on this side to rotate. The pin on the other side is fixed in the guide groove and will not idle. Therefore, when the rotating direction of the rotating shaft changes, the relative angle between the driving assemblies on both sides will change accordingly. Similarly, since the above-mentioned fixed groove is not perpendicular to the rotating shaft, the relative angle of the fixed grooves on the driving assemblies on both sides will also change accordingly, and the massage method will change accordingly.

[0013] Preferably, the driving unit comprises:

[0014] a first inclined cam for driving a first massage arm of the pair of massage arms to swing, the first inclined cam being installed on the rotating shaft in an inclined state; and

[0015] A second inclined cam for driving the second massage arm of the pair of massage arms to swing is installed on the rotating shaft in an inclined state.

[0016] Preferably, a phase difference changing mechanism is provided between one of the first inclined cam and the second inclined cam and the rotating shaft, and the phase difference changing mechanism comprises:

[0017] a toggle portion; and

[0018] A first stopper and a second stopper respectively cooperating with the toggle portion and staggered by 180° in the circumferential direction of the rotating shaft;

[0019] When the rotating shaft rotates in a first direction, the toggle portion and the first stop portion are pressed together to transmit the rotational power; when the rotating shaft rotates in a second direction opposite to the first direction, the toggle portion and the second stop portion are pressed together to transmit the rotational power.

[0020] Preferably, the shifting portion is arranged on a rotating shaft, and the first stop portion and the second stop portion are arranged on an inclined cam.

[0021] Preferably, the first stopper and the second stopper are both arranged on the rotating shaft, and the shifting part is arranged on the inclined cam.

[0022] Preferably, the toggle portion is configured as a shaft pin, and a space for the toggle portion to rotate around the prescribed axis is configured between the first stop portion and the second stop portion.

[0023] Preferably, the phase difference changing mechanism is arranged between the first inclined cam and the rotating shaft, and the second inclined cam and the rotating shaft are fixedly connected.

[0024] Preferably, an annular sleeve portion is provided on the massage arm, and the inclined cam is provided with retaining edges on both sides along its axial direction to prevent the annular sleeve portion from being separated.

[0025] The above technical solution can be further optimized through the following measures:

[0026] Preferably, the number of the driving components is two, and the two driving components are arranged at intervals along the left and right directions of the rotating shaft. The massage mode is changed by changing the relative angle of the left and right driving components through the above scheme. At the same time, the left and right driving components are arranged at intervals, leaving enough space to change the massage mode, so as to avoid collision between the massage arms on both sides when changing the massage mode. The driving component has an axial hole for the rotating shaft to pass through, and the rotating shaft passes through the axial hole to install the driving component on the rotating shaft. The diameter of the axial hole is the same as that of the rotating shaft, so that the driving component will not shake on the rotating shaft. The angle formed between the two driving surfaces is 180 degrees. On the one hand, it can be seen from the above scheme that the change in the relative angle of the left and right driving components when the rotation direction changes should be the same as the relative angle between the two driving surfaces. Combined with the requirements for angle change between kneading massage and swinging massage, the angle between the two driving surfaces is set to 180 degrees. On the other hand, when the relative angle of the two driving surfaces is 180 degrees, the two driving surfaces are on the same plane. In the guide groove on one side of the bolt fixing, a two-way bolt can be used to simultaneously fit the two driving surfaces on both sides of the rotating shaft, so as to achieve the purpose of bolt fixing. The guide groove and the outer peripheral surface are connected and fixed by a plurality of reinforcing ribs.

[0027] Preferably, the latch includes a one-way latch and a two-way latch, and the one-way latch and the two-way latch are configured such that the one-way latch is used on both sides of one driving component and the two-way latch is used on at least one side of the other driving component. From the above scheme, it can be seen that the one-way latch is arranged in the guide groove of the driving component on one side so that it can be idle at a certain angle, and the two-way latch is arranged in the guide groove of the driving component on the other side to be fixed in the guide groove, so that the driving components on both sides can produce a relative angle change when the rotation direction is changed. The rotating shaft is provided with a plurality of pin holes matching the latch, and the latch is fixedly installed in the pin holes.

[0028] Preferably, a rotation limit bump is provided on the massage arm to prevent the massage arm from rotating together with the drive assembly. The rotation limit bump is located at the other end of the massage arm for performing massage to avoid affecting the massage effect.

[0029] As an embodiment of the present invention, when the rotating shaft rotates forward, the one-way plug rotates to the position of the first stop portion in its guide groove, pushing the first stop portion to rotate the drive assembly on that side. At this time, the planes where the fixing grooves of the drive assemblies on the left and right sides are parallel to each other, and the massage arms fixed thereon swing parallel to each other as the rotating shaft rotates. The massage method at this time is swing massage.

[0030] As another embodiment of the present invention, when the rotating shaft rotates in the reverse direction, the one-way plug rotates 180 degrees to the position of the second stop portion in its guide groove, pushing the second stop portion to rotate the drive assembly on that side. At this time, a 180-degree change occurs in the relative angle of the drive assemblies on the left and right sides, and the planes where the two fixing grooves are located change from being parallel to each other to being mirror-distributed. The swinging manner of the massage arms fixed thereon also changes from being parallel to each other to mirror-swaying. The massage method at this time is changed to pinching and kneading massage.

[0031] The present invention also provides a massager that uses the above massage device.

[0032] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0033] In summary, in the above embodiments, by providing guide grooves on the drive assemblies on both sides and fixing them with one-way plugs and two-way plugs respectively, when the rotation direction of the rotating shaft changes, the drive assemblies on both sides can generate a relative angle change, and the relative angle of the drive assemblies is converted into the relative angle of the massage arms on both sides through the direction of the fixing grooves, achieving the purpose of changing the massage method only by changing the rotation direction of the motor.

[0058] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0059] Embodiment 1:

[0060] Such asFigure 1 As shown in the figure, the present invention provides a massage device, which includes a massage arm 3 for performing body massage; it also includes: a rotating shaft 2, which is used to drive the movement of the massage arm 3; and a driving component 1, which is installed on the rotating shaft 2. A fixing groove 12 is provided on the peripheral surface of the driving component 1, and the massage arm 3 is installed in the fixing groove 12; wherein semi-circular guiding grooves 11 are formed on both side surfaces of the driving component 1, driving surfaces in two opposite directions are formed in the guiding grooves 11, and a pin for pushing the driving component 1 to rotate is provided in the guiding grooves 11, and the driving component 1 is clamped and fixed by the pins in the guiding grooves 11 on both sides.

[0061] In order to enable the massage device to achieve the purpose of pinching and kneading massage during forward rotation and swinging massage during reverse rotation, the above technical solution is adopted. Among them, the left and right massage arms 3 are relatively rotatably installed in the fixing groove 12 of the driving component 1. The fixing groove 12 is set not to be perpendicular to the rotating shaft 2, and the massage arm 3 is provided with a rotating limiting protrusion 31 for restricting rotation to prevent the massage arm 3 from rotating with the driving component 1. Therefore, when the driving component 1 rotates with the rotating shaft 2, the angle of the fixing groove 12 will change with the rotation. Since the massage arm 3 cannot rotate, the end thereof will swing accordingly to perform massage.

[0062] The driving component 1 is driven to rotate by the pin on the rotating shaft 2. When the rotating direction of the rotating shaft 2 is different, the pin will respectively push two different driving surfaces to drive the driving component 1 to rotate. Since there is a guiding groove 11 between the driving surfaces, the pin idles in the guiding groove 11 on one side and will not drive the driving component 1 on this side to rotate at this time, while on the other side, the pin is fixed in the guiding groove 11 and will not idle. Therefore, when the rotating direction of the rotating shaft 2 changes, the relative angle between the driving components 1 on both sides will change accordingly. Similarly, since the above-mentioned fixing groove 12 is not perpendicular to the rotating shaft 2, the relative angle of the fixing grooves 12 on the driving components 1 on both sides will also change accordingly, and at this time the massage method will change accordingly.

[0063] As Figure 2 、 Figure 3 、 Figure 6 shown, when the rotating shaft 2 rotates forward, the one-way pin 22 rotates to the position of the first stop portion 111 in its guiding groove 11, and pushes the first stop portion 111 to rotate the driving component 1 on this side. At this time, the planes where the fixing grooves 12 of the driving components 1 on the left and right sides are located are parallel to each other, and the massage arms 3 fixed thereon are also parallel to each other when swinging with the rotation of the rotating shaft 2. At this time, the massage method is swinging massage.

[0064] As Figure 8 、 Figure 9 、 Figure 12As shown in the figure, there are two driving components 1, and the two driving components 1 are arranged at intervals in the left - right direction along the rotating shaft 2. By changing the relative angle of the left - right driving components 1 in the above - mentioned way, the massage mode is changed. At the same time, the left - right driving components 1 are arranged at intervals, leaving enough space to change the massage mode, avoiding the collision of the massage arms 3 on both sides when changing the massage mode. When the rotating shaft 2 rotates forward, the one - way pin 22 rotates to the position of the first stop portion 111 in its guide groove 11, pushing the first stop portion 111 to rotate the driving component 1 on this side. At this time, the planes where the fixing grooves 12 of the left - right driving components 1 are located are parallel to each other, and the massage arms 3 fixed on them swing parallel to each other as the rotating shaft 2 rotates. At this time, the massage mode is swing massage.

[0065] As Figure 13 , Figure 14 , Figure 15 shown, the driving component 1 has a shaft hole 13 through which the rotating shaft 2 passes. The rotating shaft 2 passes through the shaft hole 13 to install the driving component 1 on the rotating shaft 2. The diameter of the shaft hole 13 is the same as that of the rotating shaft 2, so that the driving component 1 will not shake on the rotating shaft 2. The angle formed between the two driving surfaces is 180 degrees. On the one hand, as can be seen from the above - mentioned solution, the relative angle change of the left - right driving components 1 when the rotation direction changes should be the same as the relative angle between the two driving surfaces. Considering the angle change requirements between the pinching - kneading massage and the swing massage, the angle between the two driving surfaces is set to 180 degrees. On the other hand, when the relative angle between the two driving surfaces is 180 degrees, the two driving surfaces are in the same plane. In the guide groove 11 on the side fixed by the pin, the two - way pin 23 can be used to fit the two driving surfaces on both sides of the rotating shaft 2 at the same time to achieve the purpose of pin fixing. The guide groove 11 and the outer peripheral surface are connected and fixed by a number of reinforcing ribs. The pin includes a one - way pin 22 and a two - way pin 23. The one - way pin 22 and the two - way pin 23 are configured such that the one - way pin 22 is used on both sides of one driving component 1, and the two - way pin 23 is used on at least one side of the other driving component 1. As can be seen from the above - mentioned solution, the one - way pin 22 is arranged in the guide groove 11 of one driving component 1 to enable it to rotate idly at a certain angle, and the two - way pin 23 is arranged in the guide groove 11 of the other driving component 1 to be fixed in the guide groove 11, so as to achieve the effect that the relative angle between the two driving components 1 can change when the rotation direction changes. A number of pin holes 21 matching the pins are provided on the rotating shaft 2, and the pins are fixedly installed in the pin holes 21.

[0066] Embodiment 2:

[0067] As Figure 4 , Figure 5As shown in the figure, other structures of this embodiment refer to Embodiment 1. The difference is that when the rotating shaft 2 rotates in the reverse direction, the one-way pin 22 rotates 180 degrees in its guide groove 11 to the position of the second stop portion 112, pushing the second stop portion 112 to rotate the driving assembly 1 on this side. At this time, the relative angle between the driving assemblies 1 on the left and right sides changes by 180 degrees, and the planes where the two fixing grooves 12 are located change from being parallel to each other to being mirror-image distributed. The swinging modes of the massage arms 3 fixed thereon also change from being parallel to each other to mirror-image swinging. At this time, the massage mode is changed to pinching and kneading massage.

[0068] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
