Description

Technical Field

[0001] The present application relates to the technical field of massage instruments, and in particular to a driving mechanism of a massage instrument. Background Art

[0002] Massage is to stimulate the external organs of the human body through the continuous change of techniques, directly or indirectly stimulate the muscles, bones, joints, ligaments or nerves through the conduction of acupuncture points, meridians or nervous systems, and produce local or systemic reactions. Massage has the effects of relaxing muscles, relieving pain, and promoting blood circulation in the body. Thanks to the development of new materials and technological progress, massage instruments have been continuously improved in the bionic level of simulating massage techniques, realizing the requirements of miniaturization and precise control of massage instruments.

[0003] In the related art, a massage instrument includes a shell and a vibration head arranged at the end of the shell. A circuit board, a vibration motor and a battery are arranged in the cavity of the shell. The vibration motor and the battery are electrically connected to the circuit board. The vibration motor is used to control the vibration of the vibration head.

[0004] The above technical solution still has the following defects: the massage instrument generally only has a fixed vibration function, and the head of the shell cannot be extended or retracted, which results in the massage instrument having a relatively single function, a relatively light massage force, and a relatively poor massage effect. Utility Model Content

[0005] In order to improve the massage effect of a massage instrument, the present application provides a driving mechanism of the massage instrument.

[0006] The present application provides a driving mechanism of a massage instrument, which adopts the following technical solution:

[0007] A driving mechanism of a massage instrument includes a driving member and a power source arranged at one end of the driving member, the driving member includes a top plate, a rotating member is connected between the top plate and the power source, the power source is used to drive the rotating member to rotate, a supporting member is provided on the circumferential side wall of the rotating member, the supporting member performs periodic lifting and reciprocating motion along the length direction of the rotating member, and the supporting member is used to be clamped with a shell.

[0008] By adopting the above technical solution, after the power source is started, the power source controls the rotation of the rotating part. As the rotating part rotates, the shell linked with the support part will perform periodic lifting and reciprocating motion, thereby achieving the effect of telescopic massage instrument. Compared with massage instruments that achieve massage through vibration, telescopic massage instruments can increase the massage intensity, stimulate the body's acupuncture points, effectively relieve the blockage of meridians, and achieve the effect of decompression and relieving human fatigue. Secondly, the driving part is arranged inside the shell, making full use of the space inside the shell, so that the overall structural layout of the massage instrument is more reasonable.

[0009] Optionally, the rotating member is configured as a reciprocating screw.

[0010] By adopting the above technical solution, through the rotation of the reciprocating screw, the spiral groove side of the reciprocating screw pushes the support to make axial reciprocating motion. There is no need to frequently change the direction of the power source during operation, thereby reducing the workload of the power source and helping to extend the service life of the power source. The difference between the dynamic and static friction of the reciprocating screw is extremely small, which can achieve smooth movement of the support, is not easy to wear, has a long service life, and maintains good accuracy. Secondly, the reciprocating screw is sensitive, is not prone to low-speed creeping, and has a high transmission efficiency of 90%-96%.

[0011] Optionally, the support member includes a lifting seat and a sliding member, the sliding member includes a crescent pin and an insertion rod connected to the crescent pin, the crescent pin is arranged in a threaded groove of the rotating member, the insertion rod is connected to the lifting seat, and the lifting seat is used to be clamped with the shell.

[0012] By adopting the above technical solution, the lifting seat and the rotating member are connected by a sliding member, and the curved surface of the crescent pin can be well fitted with the inner wall of the thread groove, so that the crescent pin slides smoothly along the setting direction of the thread groove, and the lifting seat is also lifted smoothly, with high movement stability, and the lifting seat is not prone to jamming. The massage instrument works stably and can reduce maintenance costs.

[0013] Optionally, the lifting seat is provided with a through hole for the rotating member to pass through, and the lifting seat is provided with an insertion hole connected to the through hole, and the insertion hole is used for inserting the insertion rod.

[0014] By adopting the above technical solution, the rotating member is arranged through the lifting seat, so that the lifting of the lifting seat is more stable, safe and reliable, and can save space.

[0015] Optionally, a mounting hole is provided on the side wall of the lifting seat, the mounting hole is connected to the through hole, the mounting hole is connected to the insertion hole, a fixing block is provided in the mounting hole, a limiting groove is provided on the side of the fixing block close to the insertion hole, and the limiting groove is used for inserting the insertion rod.

[0016] By adopting the above technical solution, the convenience of assembling, manufacturing and using the lifting seat and the sliding part can be improved. During assembly, the lifting seat is firstly sleeved on the outside of the rotating part, and the fixed block is moved out of the mounting hole; then the sliding part is passed through the mounting hole, so that the crescent pin is inserted into the rotating part, and the insertion rod is set in the mounting hole; finally, the fixed block is reinserted into the mounting hole, so that the insertion rod is limited between the insertion hole and the limiting groove.

[0017] Optionally, a clamping block is connected to one side of the fixing block, and the lifting seat is provided with a clamping slot for the clamping block to be clamped into.

[0018] By adopting the above technical solution, on the one hand, the snap-on structure has a reliable connection, is simple and convenient to use, and can quickly complete the assembly of the fixed block. The connection strength between the fixed block and the lifting seat can be effectively met without the need for additional fasteners. On the other hand, the fixed block is detachable. If the support fails, it is convenient for maintenance personnel to carry out maintenance, which reduces the difficulty of maintenance and thus improves maintenance efficiency.

[0019] Optionally, a guide rod is connected between the top plate and the power source, the lifting seat is provided with a through hole for the guide rod to pass through, and the lifting seat performs periodic lifting and reciprocating motion along the length direction of the guide rod.

[0020] By adopting the above technical solution, the guide rod can guide and limit the lifting seat. On the one hand, it allows the lifting seat to slide upward and downward more smoothly along the length direction of the guide rod; on the other hand, since the connection between the insertion rod and the lifting seat is plug-in, the guide rod can limit the lifting seat to make circular motion with the central axis of the insertion rod as the center.

[0021] Optionally, at least two groups of guide rods are provided.

[0022] By adopting the above technical solution, the stability of the lifting seat when sliding up and down can be further enhanced, so that the lifting seat is not prone to tilt or shake when lifting, thereby ensuring that the lifting seat stably drives the shell to lift.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. By setting a reciprocating screw and a support, the massage instrument can achieve a telescopic effect. The telescopic massage instrument can increase the massage intensity, stimulate the acupuncture points of the body, effectively relieve the blockage of meridians, and achieve the effect of decompression and relieving human fatigue;

[0025] 2. By setting the guide rod, the lifting seat can be lifted and lowered more smoothly and stably, and the lifting seat is not prone to tilt or shake. BRIEF DESCRIPTION OF THE DRAWINGS

The driving member 1 includes a top plate 11, a rotating member 12, a support member 13 and a guide rod 14. The top plate 11 is arranged at one end of the rotating member 12 away from the power source 2. The guide rod 14 is fixedly connected between the top plate 11 and the power source 2. Three guide rods 14 are arranged circumferentially along the central axis of the rotating member 12. In the embodiment of the present application, the power source 2 is preferably a servo motor, and the rotating shaft of the servo motor is fixedly connected to the end of the rotating member 12.

[0034] The circumferential outer wall of the rotating member 12 is rotatably connected with the support member 13, and the guide rod 14 is inserted through the support member 13. The support member 13 is used to be clamped with the shell. The rotating member 12 is set as a reciprocating screw, and the reciprocating screw has two thread grooves with the same pitch and opposite rotation directions. The upper and lower ends of the reciprocating screw are connected by a transition curve. The power source 2 controls the rotation of the reciprocating screw, and the side wall of the thread groove pushes the support member 13 placed in the thread groove to perform periodic lifting and reciprocating motion, that is, the support member 13 slides up and down along the length direction of the guide rod 14, thereby driving the shell to slide up and down, achieving the effect of telescopic massage instrument.

[0035] Reference Figure 1 and Figure 2The support member 13 includes a lifting seat 131, a sliding member 132 and a fixed block 133. The lifting seat 131 is provided with a through hole 1311 for the rotating member 12 to pass through. The through hole 1311 is arranged at the center position of the lifting seat 131, that is, the central axis of the lifting seat 131 coincides with the central axis of the through hole 1311. The upper end surface of the lifting seat 131 is arranged in a circular shape, and the side edge of the upper end surface of the lifting seat 131 is used to engage with the inner wall of the shell, so that the driving member 1 is arranged inside the shell. The lifting seat 131 is provided with a through hole 1315 for the guide rod 14 to pass through. There are three through holes 1315, and the through holes 1315 correspond to the guide rod 14 one by one. The guide rod 14 guides and limits the lifting seat 131, and enhances the stability of the lifting seat 131 when sliding up and down.

[0036] The sliding member 132 includes a crescent pin 1321 and an insertion rod 1322, the crescent pin 1321 and the insertion rod 1322 are fixedly connected, the side of the crescent pin 1321 close to the rotating member 12 is set as a concave surface, and the side of the crescent pin 1321 close to the insertion rod 1322 is set as a convex surface. The crescent pin 1321 is set in the thread groove of the rotating member 12, and the concave surface of the crescent pin 1321 fits with the inner wall of the thread groove, so that the crescent pin 1321 slides smoothly along the setting direction of the thread groove. The crescent pin 1321 is pointed at both ends and wide in the middle, so that the crescent pin 1321 is not prone to jamming when sliding in the thread groove. The lifting seat 131 is provided with a socket 1312 for inserting the insertion rod 1322, and the length direction of the socket 1312 is perpendicular to the length direction of the through hole 1311.

[0037] Reference Figure 2 and Figure 3 The lifting seat 131 is provided with a mounting hole 1313 connected to the insertion hole 1312. The mounting hole 1313 is also connected to the through hole 1311. When the sliding member 132 is installed, the crescent pin 1321 passes through the mounting hole 1313 and is inserted into the threaded groove. A fixing block 133 is arranged in the mounting hole 1313. The outer wall of the fixing block 133 is in contact with the inner wall of the mounting hole 1313. A limiting groove 1331 is arranged on the side of the fixing block 133 close to the insertion hole 1312. The cavity formed between the limiting groove 1331 and the insertion hole 1312 is used for inserting the plug rod 1322, and the plug rod 1322 can be limited. The fixing block 133 is fixedly connected with a clamping block 1332 on both sides. The clamping block 1332 is symmetrically arranged along the central axis of the fixing block 133.
