Description

Technical Field

[0001] The present invention relates to the technical field of massage instruments, and particularly to a hammering mechanism with a hammer clamping function and a neck massage device having the mechanism. Background Art

[0002] More and more people have shoulder and neck discomfort due to reasons such as sitting for a long time. To relieve this discomfort, a massage device can be used to massage the uncomfortable area, relieve problems such as headache and muscle stiffness, play a role in soothing nerves, promoting blood circulation, reducing fatigue, relaxing the body, and stretching the mood.

[0003] In the existing massage devices, a motor is usually used to drive the massage head to perform a rotational motion. Taking a neck massage device as an example, the neck massage device is sleeved on the human neck, and only the massage head rotates in the corresponding area to achieve the kneading massage effect.

[0004] Chinese patent application with publication number CN114533507A discloses a neck massager with both kneading and knocking functions. The knocking massage mechanism of this neck massager can only perform a reciprocating circular arc motion within a large range to generate a knocking function, but this knocking massage mechanism cannot produce a clamping massage effect. Therefore, the massage and relaxation effect of this neck massager on the shoulder and neck is not ideal enough.

[0005] Therefore, in view of the deficiencies of the prior art, it is very necessary to provide a hammering mechanism with a hammer clamping function and a neck massage device having the mechanism to solve the deficiencies of the prior art. Summary of the Invention

[0006] One of the purposes of the present invention is to avoid the deficiencies of the prior art and provide a hammering mechanism with a hammer clamping function, which can produce the effects of hammering and clamping.

[0007] The above object of the present invention is achieved by the following technical measures:

The first transmission component and the second transmission component are both in transmission connection with the driving component, and the first transmission component and the second transmission component are both in transmission connection with the hammer arm component.

[0009] When only the first transmission component is in transmission, the hammer arm component performs a reciprocating circular arc motion, and the central angle of the circular arc is defined as the total central angle.

[0010] Divide the total central angle into multiple sub - central angles. When the first transmission component and the second transmission component drive together, the hammer arm component sequentially passes through the ranges of multiple sub - central angles and reciprocates back and forth within the range of each sub - central angle.

The other end of the sleeve arm is assembled with one end of the connecting arm. The ball head at the other end of the connecting arm is rotatably assembled at the fixing member of the hammer arm component.

[0020] Preferably, the fixing member is provided with a spherical cavity, and the ball head is rotatably assembled inside the spherical cavity.

[0021] Preferably, the driving assembly is provided with a motor and a double gear. The first rotating shaft of the motor meshes with one layer of the double gear. The second rotating shaft of the motor is in transmission connection with a transmission belt. The other layer of the double gear meshes with the first gear of the first transmission assembly.

[0022] When the transmission belt drives the pulley to rotate, the state where the pulley drives the spring to tighten is regarded as the working state of the forward rotation of the second rotating shaft. At this time, the spring drives the rotating rod to rotate.

[0023] When the transmission belt drives the pulley to rotate and the pulley does not drive the spring to tighten, it is regarded as the working state of the reverse rotation of the second rotating shaft. At this time, the rotating rod does not rotate with the rotation of the belt.

The first transmission component and the second transmission component are both in transmission connection with the driving component, and the first transmission component and the second transmission component are both in transmission connection with the hammer arm component. When only the first transmission component is in transmission, the hammer arm component performs a reciprocating circular arc motion, and the central angle of the circular arc is defined as the total central angle, and the total central angle is divided into multiple sub-central angles. When the first transmission component and the second transmission component are in common transmission, the hammer arm component sequentially passes through the ranges of multiple sub-central angles and performs a back-and-forth reciprocating motion within each range of the sub-central angles. In the hammering mechanism with the function of hammering and pinching of the present invention, under the action of the first transmission component and the second transmission component, when the hammer arm component performs an overall reciprocating motion within the circular arc range, a hammering effect is generated.

When the included angle with the massage plane of the user is relatively small, a pressing action is generated on the user, thereby greatly improving the massage effect.

[0064] The technical solution of the present invention will be further described in conjunction with the following embodiments.

[0065] Embodiment 1.

[0066] A hammering mechanism with a hammer clamping function, as Figures 1 to 14 shown, is provided with a driving assembly 100, a hammer arm assembly 200, a first transmission assembly 300 for converting the rotational motion generated by the driving assembly 100 into a piston motion, and a second transmission assembly 400 for transmitting the rotational motion generated by the driving assembly 100 to the hammer arm assembly 200. Both the first transmission assembly 300 and the second transmission assembly 400 are in transmission connection with the driving assembly 100, and both the first transmission assembly 300 and the second transmission assembly 400 are in transmission connection with the hammer arm assembly 200.

[0067] It should be noted that the hammering mechanism of the present invention will be assembled and used in a seat body or a housing such as an assembly seat, and the specific description of such a seat body or housing is omitted here.

[0068] When only the first transmission assembly 300 is in transmission, the hammer arm assembly 200 performs a reciprocating circular arc motion. It should be noted that the reciprocating circular arc motion mentioned in the present invention means that with the center of the first bearing 260 in the hammer arm assembly 200 as the center of the hammer arm assembly 200, the hammer head 210 performs a reciprocating motion within a certain radian range with this center as the center and the distance between the hammer head 210 and this center as the radius, forming a hammering and knocking effect.

[0069] Define the central angle of this arc as the total central angle. As Figure 4 shown, the hammer arm assembly 200 performs a circular arc reciprocating motion within the area where the central angle is A. It should be noted that in this case, the hammer arm assembly 200 generates a hammering massage function.

[0070] Divide the total central angle into multiple sub - central angles. For example, in the figure, the total central angle is A, and the multiple sub - central angles are B, C, and D respectively. When the first transmission assembly 300 and the second transmission assembly 400 are jointly in transmission, the hammer arm assembly 200 sequentially passes through multiple sub - central angle ranges and performs a back - and - forth reciprocating motion within each sub - central angle range. In this embodiment, Figure 5For example, the hammer arm assembly 200 performs circular reciprocating motions within the regions of sub-central angles B, C, and D respectively. As a whole, the hammer arm assembly 200 first performs circular reciprocating motions within the region of central angle B for a period of time, then enters the region of central angle C and performs circular reciprocating motions within the region of central angle C for a period of time, and finally enters the region of central angle D and performs circular reciprocating motions within the region of central angle D for a period of time.

[0071] It should be noted that in this state, when the hammering mechanism is in use, the hammer arm assembly 200 sequentially passes through multiple sub-central angle ranges, that is, it generates reciprocating motions at different angles. During this process, the hammer arm assembly 200 acts on the user, exerting a pressing and pushing force on the user, forming the effect of reciprocating motions at different angles. Within different sub-central angle ranges, the force effect of squeezing the skin is also different; at the same time, the hammer arm assembly 200 also forms a hammering effect during the reciprocating process. This state where pressing and pushing coexist with hammering is the pinching massage function described in the present invention.

[0072] The drive assembly 100 of the present invention is provided with a motor 110 and a double gear 120. The first rotating shaft 130 of the motor 110 meshes with one layer of the double gear 120, the second rotating shaft 140 of the motor 110 is in transmission connection with a transmission belt 410, and the other layer of the double gear 120 meshes with a first gear 310.

[0073] The drive assembly 100 drives the first transmission assembly to move through the first rotating shaft 130, and the drive assembly 100 drives the second transmission assembly 400 to move through the second rotating shaft 140.

[0074] The specific driving method of the drive assembly 100 of the present invention is as follows:

[0075] When the transmission belt 410 drives the pulley 420 to rotate, the state where the pulley 420 drives the spring 450 to contract is defined as the working state of the forward rotation of the second rotating shaft 140. At this time, the spring 450 drives the rotating rod 430 to rotate;

[0076] When the transmission belt 410 drives the pulley 420 to rotate and the pulley 420 does not drive the spring 450 to contract, this state is defined as the working state of the reverse rotation of the second rotating shaft 140. At this time, the rotating rod 430 does not rotate along with the rotation of the transmission belt 410.

[0077] It should be noted that when the second rotating shaft 140 rotates forward, the spring 450 contracts and drives the rotating rod 430 to rotate. The rotating rod 430 is connected to the eccentric wheel 240. The arm body 220 generates a deflecting force through the assembling end 242 of the eccentric wheel 240, and the rotating rod 430 generates a pushing and pulling force through the eccentric wheel 240. Under the deflecting force and pulling action, the arm body 220 forms a pinching massage function.

[0078] When the second rotating shaft 140 rotates reversely, the transmission belt 410 drives the belt pulley 420 to rotate. The belt pulley 420 drives the spring 450 to relax, and the rotating rod 430 does not rotate. The rotating rod 430 does not generate a deflecting force on the eccentric wheel 240. The arm body 220 is only under the pushing and pulling force of the rotating rod 430, and the rotating rod 430 pulls the arm body 220 to perform a reciprocating knocking action at the assembling end 242, generating a hammering effect.

[0079] Among them, the first transmission component 300 is provided with a first gear 310 and a connecting rod part 320. The first gear 310 meshes with the driving component 100, specifically meshes with the first rotating shaft 130. One end of the connecting rod part 320 is assembled with the first gear 310, and the other end of the connecting rod part 320 is assembled with the hammer arm component 200.

[0080] Specifically, the first gear 310 is provided with a gear body 311 and an eccentric boss 312. The eccentric boss 312 is fixedly connected to a bottom surface of the gear body 311. The gear body 311 meshes with the first rotating shaft 130, and the outer surface of the eccentric boss 312 is sleeved with one end of the connecting rod.

[0081] It should be noted that the eccentric boss 312 means that its center does not overlap with the center of the gear body 311. Taking the gear body 311 as the center of revolution, the whole rotates around the gear body 311. At the same time, the first transmission component 300 is respectively assembled with the eccentric boss 312 and the hammer arm component 200. Under the common constraint of the eccentric boss 312 and the hammer arm component 200 on the connecting rod part 320, finally the connecting rod part 320 performs a reciprocating motion. In this way, the connecting rod part 320 generates a force on the end of the arm body 220 in the front and back directions along a straight line. When the middle part of the arm body 220 is movably assembled to the support rod, under the reciprocating pulling action of the connecting rod part, the arm body rotates around the support rod reciprocally, and the hammer head 210 makes an arc reciprocating motion.

[0082] The connecting rod part 320 is provided with a sleeve arm 321 and a connecting arm 322. One end of the sleeve arm 321 is sleeved on the outer periphery of the eccentric boss 312. The other end of the sleeve arm 321 is assembled with one end of the connecting arm 322. The other end of the connecting arm 322 is rotatably assembled with the hammer arm component 200. One end of the connecting arm 322 is provided with a ball head 323, and the ball head 323 is rotatably assembled with the hammer arm component 200.

[0083] It should be noted that the first transmission assembly 300 of the present invention converts the rotational motion of the drive assembly 100 into a linear reciprocating motion back and forth, generating a reciprocating pushing and pulling force on the hammer arm assembly 200.

[0084] The second transmission assembly 400 of the present invention is provided with a rotating rod 430, a spring 450, a pulley 420, a second bearing 440, and a transmission belt 410. The pulley 420 is rotatably assembled on the outer surface of the rotating rod 430. The rotating rod 430 is in transmission assembly with the hammer arm assembly 200. One end of the spring 450 is fixedly connected to the pulley 420, and the other end of the spring 450 is fixedly connected to the rotating rod 430. The transmission belt 410 is assembled on the second rotating shaft 140 of the drive assembly 100 and the pulley 420. The pulley 420 and the second bearing 440 are rotatably assembled on the outer surface of the rotating rod 430 from the outside to the inside.

[0085] It should be noted that when the drive assembly 100 rotates in one direction, the spring 450 is in a tightened state. Then the spring 450 drives the rotating rod 430 to rotate. The rotating rod 430 transmits the acting force to the hammer head 210 and the arm body 220 through the eccentric wheel 240 of the hammer arm assembly 200. The hammer head 210 and the arm body 220 are simultaneously driven by the first transmission assembly 300 to perform reciprocating back and forth movements within the range of each sub-central angle. When the drive assembly 100 rotates in the other direction, the spring 450 is in a relaxed state. At this time, the rotating rod 430 does not rotate, and the hammer arm assembly 200 only performs a reciprocating circular arc movement under the drive of the first transmission assembly 300.

[0086] The hammer arm assembly 200 of the present invention is provided with a hammer head 210, an arm body 210, an eccentric wheel 240, a first bearing 260, and a fixing member 230. The hammer head 210 and the fixing member 230 are respectively fixedly assembled at both ends of the arm body 210. The eccentric wheel 240 is fixedly assembled at the end of the rotating rod 43. The arm body 210 is movably assembled on the eccentric wheel 240. The fixing member 230 is provided with a spherical cavity 250, and the ball head 323 is rotatably assembled inside the spherical cavity 250.

[0087] The eccentric wheel 240 is provided with a wheel body 241 and an assembly end 242. The assembly end 242 is integrally connected to the wheel body 241, and the center of the assembly end 242 does not overlap with the center of the wheel body 241. The assembly end 242 is sleeved with the first bearing 260, and the wheel body 241 is fixedly sleeved with the rotating rod 430. The arm body 210 and the eccentric wheel 240 are movably assembled through the first bearing 260, and the first bearing 260 is sleeved on the outer surface of the eccentric wheel. The center of the first bearing 260 is the center of the circular arc of the present invention.

[0088] When the motor 110 rotates forward, the second rotating shaft 140 rotates forward. At this time, the transmission belt 410 drives the pulley 420 to rotate. Due to the rotation of the pulley 420, the spring 450 fixed at one end to the pulley 420 is increasingly tightened, and finally drives the rotating rod 430 to rotate. With the rotation of the rotating rod 430, the eccentric wheel 240 assembled at the end of the rotating rod 430 also rotates with the rotation of the rotating rod 430. Under the action of the structure of the eccentric wheel 240, the assembly end 242 rotates eccentrically relative to the second rotating shaft 140. At this time, the arm body 220 sleeved on the assembly end 242, under the combined action of the eccentric rotation of the second rotating shaft 140 and the pushing and pulling of the connecting rod portion 320, causes the hammer head 210 and the arm body 220 to perform circular reciprocating motions within each sub-central angle respectively.

[0089] Conversely, when the motor 110 rotates in reverse, the second rotating shaft 140 rotates in reverse. At this time, the transmission belt 410 drives the pulley 420 to rotate. The spring 450 fixed on the pulley 420 is in a relaxed state, and at this time the rotating rod 430 does not rotate either. The eccentric wheel 240 assembled at the end of the connecting rod portion 320 is stationary relative to the rotating rod, and the assembly end 242 of the eccentric wheel is also stationary. At this time, the arm body 220 movably assembled on the assembly end 242 rotates around the stationary assembly end 242. In this state, when the connecting rod portion 320 reciprocally pushes the fixing member 230 at the lower part of the arm body 220, the arm body 220 performs a reciprocating knocking action.

[0090] The function of the spherical cavity 250 and the spherical head 323 of the present invention is to form a joint movement effect. The connecting rod portion 320 does not move strictly in a straight line, but has a piston movement with left and right swings. Moreover, the accommodating relationship of the spherical head 323 in the spherical cavity 250 can prevent damage to the arm body 220 during left and right swings.

[0091] The inner surface of the transmission belt 410 of the present invention is provided with a plurality of annular protrusions, and the plurality of annular protrusions are distributed in parallel; the outer surface of the pulley 420 is provided with a first annular groove matching the annular protrusions; the annular protrusions are fitted into the first annular groove.

[0092] It should be noted that the transmission between the annular protrusions, the first annular groove and the second annular groove between the second rotating shaft 140 and the pulley 420 of the present invention is continuous, and it has been verified by multiple experiments that it can improve the force during hammering.

[0093] The applicant replaced the transmission between the second rotating shaft 140, the transmission belt 410 and the pulley 420 with an intermittent transmission as a comparative experiment. For example, the outer surface of the second rotating shaft 140 has a toothed structure, the inner surface of the transmission belt 410 also has a toothed structure, and the outer surface of the pulley 420 also has a toothed structure, so that the transmission belt 410 meshes with the second rotating shaft 140 and the pulley 420 for transmission. In the comparative experiment, the force during hammering increased by a small amount and then a large amount.

[0094] It should also be noted that the principle of the hammering mechanism of the present invention for reciprocating motion within multiple sub-central angles is that since the arm body 210 is assembled at the assembly end 242 of the eccentric wheel 240, when the hammer arm assembly 200 is only under the action of the second transmission assembly 400, due to the deviation of the assembly end 242, the arm body 210 and the hammer head 210 will perform circular reciprocating motion within the area with a central angle of A. However, at this time, the first transmission assembly 300 generates a pushing and pulling force on the hammer arm assembly 200, thereby restricting the rotation of the arm body 210 at the assembly end 242, thus forming circular reciprocating motion within each of the multiple sub-central angles.

[0095] The working principle of the hammering mechanism with a hammer clamping function of the present invention is as follows:

[0096] When the motor 110 starts forward, the second rotating shaft 140 of the motor 110 drives the belt pulley 420 through the transmission belt 410, and the belt pulley 420 drives the spring 450 to start tightening. When the spring 450 is tightened to the point where it can no longer contract, the spring 450 drives the rotating rod 430 to rotate, and the rotating rod 430 drives the arm body 220 to rotate. At this time, the first rotating shaft 130 of the motor 110 drives the double gear 120 to rotate forward, the double gear 120 drives the first gear 310 to rotate, the first gear 310 drives the connecting rod part 320 to perform a rotary piston motion, and the end of the arm body 220 generates a force in the front and back directions along a straight line. Under the combined action of the rotating rod 430 and the connecting rod part 320, the middle part of the arm body 220 passes through multiple sub-central angle ranges in sequence with the central axis of the rotating rod 430 and performs reciprocating motion back and forth within each sub-central angle range, ultimately causing the hammer head 210 to generate a clamping force.

[0097] When the motor 110 starts in reverse, the second rotating shaft 140 of the motor 110 drives the belt pulley 420 through the transmission belt 410, and the belt pulley 420 drives the spring 450 to relax. At this time, the rotating rod 430 does not rotate, so the belt pulley 420 has no effect on the hammer arm assembly 200; the first rotating shaft 130 of the motor 110 drives the double gear 120 to rotate in reverse, the double gear 120 drives the first gear 310 to rotate, the first gear 310 drives the connecting rod part 320 to perform a rotary piston motion, and the end of the arm body 220 generates a force in the front and back directions along a straight line. The middle part of the arm body 220 performs overall reciprocating motion within the circular arc range with the central axis of the rotating rod 430, ultimately causing the hammer head 210 to generate an overall back-and-forth knocking force.

[0098] It should be noted that the hammering mechanism of the present invention can adjust the size and number of sub-central angles according to the recorded technical solutions and through the electronic control of the motor 110, the eccentricity of the eccentric boss 312 and the eccentric wheel 240, etc., so as to realize the adjustment of the clamping massage function.

[0099] The hammering mechanism with the function of hammer clamping, under the action of the first transmission component 300 and the second transmission component 400, makes the whole reciprocating motion within the arc range of the hammer arm component 200 to produce a hammering effect. When the hammer arm component 200 makes a reciprocating motion back and forth within each sub-central angle range, it can make a reciprocating motion back and forth at different angles, and has a pressing and pushing effect on the user. This action mode forms an effect that the hammer arm head acts on the user's skin to simultaneously perform reciprocating pushing, squeezing and knocking actions, improving the massage dimension method and the massage effect.

[0100] Embodiment 2.

[0101] A hammering mechanism with the function of hammer clamping, as Figure 15 shown, has the same other features as Embodiment 1, and also has the following features: there are multiple first transmission components 300 and multiple hammer arm components 200. In this embodiment, there are specifically two first transmission components 300 and two hammer arm components 200.

[0102] The number of the first transmission components 300 is the same as the number of the hammer arm components 200, and the first transmission components 300 and the hammer arm components 200 are in one-to-one correspondence. The first gear 310 of at least one first transmission component 300 meshes with the double gear 120.

[0103] It should be noted that the multiple first transmission components 300 of the hammering mechanism with the function of hammer clamping in this embodiment drive each other, so that multiple first transmission components 300 and hammer arm components 200 can be simultaneously driven by the same driving component 100 to move simultaneously, thus reducing the setting of the driving component 100.

[0104] Embodiment 3.

[0105] A neck massage device has a hammering mechanism with the function of hammer clamping as in Embodiment 1 or 2. In this embodiment, there are specifically two first transmission components 300 and two hammer arm components 200.

[0106] The neck massage device is further provided with a housing and a rotary massage mechanism 500. The rotary massage mechanism 500 and the hammering mechanism with the function of hammer clamping are both assembled inside the housing 600, and the rotary massage mechanism 500 is assembled on the first gear 310 of the first transmission component 300, as Figure 16 and 17 .

[0107] The whole rotary massage machine of the present invention rotates following the first gear 310.

[0108] It should be noted that both the hammering mechanism and the rotary massage mechanism 500 of the present invention are driven by the same motor 110. When the motor 110 rotates forward, the hammering mechanism produces a clamping effect, and the rotary massage mechanism 500 rotates. When the two are closest to each other, a greater pressing force can be generated on the user, thereby better improving the massage effect.

[0109] With the piston movement of the first transmission component 300, the neck massage device drives the hammer arm component 200 to perform an arc reciprocating movement, thereby generating a knocking force and achieving a hammering effect. At the same time, the rotary massage mechanism 500 of the hammering mechanism with a hammer clamping function simultaneously produces a rotary massage effect. The neck massage device has rotary massage and hammering massage effects, so the massage and relaxation effect on the shoulders and neck is obvious.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
