Description

Technical field:

[0001] The utility model relates to the technical field of rotary transmission, in particular to a rotary structure which can be used in various massage devices. Background technology:

[0002] As people pay more attention to their health, more and more people are actively participating in sports and fitness. At the same time, various types of massage equipment have gradually come into people's view, and the way of relaxing after sports and fitness with massage equipment has gradually been accepted by people. The more common massage equipment includes wearable massage equipment, neck-hanging massagers, fascia guns, etc. Moreover, massage equipment is now popular not only in the sports circle, but also among the general public. Even if many people do not have the habit of sports and fitness, they will buy one home to relax and relieve the soreness and tension caused by sitting still for a long time and working at a desk for a long time.

[0003] During the human body's exercise, skeletal muscles are dominated and controlled by the nervous system. After exercise, the muscles no longer contract and should indeed be in a relaxed state, but sometimes the nerves are still in an excited state. This may lead to continued stiffness, tension and discomfort in the skeletal muscles. At the same time, if you maintain a posture for a long time, such as sitting for a long time or working at a desk, the lower back and waist of the human body will experience various discomforts. This is also because the related muscles and fascia are in a state of contraction and work for a long time, causing damage and inflammation, and there is no time to recover and adapt. Therefore, whether it is after exercise or sitting for a long time, it is necessary to relax some muscles.

[0004] In principle, most massage devices mainly use a specially designed high-speed motor inside to drive the massage head through a special transmission mechanism, moving it back and forth at a high beat rate per minute. The motor drives the pressing component to simulate the kneading action of the human hand to relax, or, through the force exerted on the tissue by high-frequency vibration, the pressure is transmitted layer by layer to the fat, superficial fascia, deep fascia, and muscles.

[0005] At present, it is more common in the market that the transmission mechanism between the motor and the massage head in the massage equipment generally adopts an eccentric wheel connected to the motor, and a driving arm is connected to the eccentric wheel, and the driving arm is connected to the massage head, and the eccentric wheel is driven by the motor to rotate, and the driving arm is driven to do reciprocating motion to realize the massage function, such as: the Chinese utility model patent with patent announcement number CN211610680U discloses a fascia gun transmission mechanism and a fascia gun, which includes: the rotation center of the main tooth part of the motor is perpendicular to the rotation center of the transmission tooth part, the main tooth part and the transmission tooth part are vertically changed in direction, the transmission tooth part is connected to the eccentric wheel, the eccentric wheel is limited to rotate on the casing, the eccentric shaft of the eccentric wheel is rotatably connected to the driving arm, and the driving arm is rotatably connected to the piston rod, the piston rod is limited to reciprocate on the head, and the connecting shaft of the motor is parallel to the piston rod. Compared with the prior art, it adopts a primary transmission, the connecting shaft of the motor is not rigidly connected to the eccentric wheel, and the impact on the motor shaft is reduced.

[0006] However, there are the following deficiencies in the existing massage devices:

[0007] 1. In this technical solution, at least three transmissions are required from the motor to the massage head: a. between the main gear of the motor and the transmission gear on the eccentric wheel; b. between the eccentric wheel and the drive arm; c. between the drive arm and the massage head. When such a structure is running at high speed, not only is the internal mechanical vibration relatively large, but the wear between the transmission parts is relatively more serious, and the service life is poor.

[0008] 2. In this technical solution, the transmission direction of the driving mechanism has not changed, resulting in the entire massage product being T-shaped and having a large volume, which is inconvenient to store and carry.

[0009] In view of this, the inventor proposes the following technical solution. Utility model content:

[0010] The utility model aims to overcome the shortcomings of the prior art and provide a simple and compact rotating structure, which can be applied to various massage devices.

[0012] Furthermore, in the above technical solution, the transmission mechanism is a bevel gear set, the first transmission member is a first bevel gear arranged on the shaft section, and the second transmission member is a second bevel gear arranged on the drive assembly and meshing with the first bevel gear.

[0013] Furthermore, in the above technical solution, the angle between the first bevel gear and the second bevel gear is 80°-100°.

[0014] Furthermore, in the above technical solution, the transmission mechanism is a worm gear, the first transmission member is a worm gear arranged on the shaft section, and the second transmission member is a turbine gear arranged on the drive assembly and meshing with the worm gear.

[0015] Furthermore, in the above technical solution, the shell includes a first shell and a second shell covering the first shell, the first shell is formed with a positioning portion for limiting the shaft segment, and correspondingly, the second shell is formed with a pressing portion matching the positioning portion.

[0016] Furthermore, in the above technical solution, a first slot and a second slot are respectively formed in the positioning portion.

[0017] Furthermore, in the above technical solution, the driving assembly includes a first motor and a reduction gear box installed on the first motor, and the second transmission member is connected to the output shaft of the reduction gear box.

[0018] Furthermore, in the above technical solution, a massage head is installed on the bent section of the rotating rod extending out of the shell.

[0020] Furthermore, in the above technical solution, a first accommodating groove for limiting the position of the driving assembly and a second accommodating groove for limiting the position of the second motor are formed in the housing.

[0021] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0022] 1. In the utility model, the driving assembly drives the rotation of the rotating rod through the transmission mechanism, transmits the rotation through the transmission mechanism, and changes the rotation direction, thereby achieving the adjustment of the rotation direction within an effective space, and is suitable for various handheld massage devices.

[0023] 2. Compared with the existing structure, the utility model can directly drive the rotating rod to rotate through a bevel gear set or a worm gear, reducing the transmission level and improving the transmission efficiency.

[0031] The utility model is further described below in conjunction with specific embodiments and drawings.

[0032] See Figures 1 to 5 As shown, it is the first embodiment of the utility model, which includes a housing 1, a driving assembly 2 installed in the housing 1, and a rotating rod 3 driven by the driving assembly 2, and is characterized in that:

[0033] The rotating rod 3 includes: an integrally formed bending section 31 and an axle section 32. The bending section 31 extends out of the housing 1 and is bent relative to the axle section 32. The greater the bending angle of the bending section 31 relative to the axle section 32, the greater the rotation swing amplitude of the final shape. In this embodiment, the preferred bending angle is 10°-40°. The axle section 32 serves as the central axis when the rotating rod 3 rotates.

[0034] A transmission mechanism 7 is provided between the driving assembly 2 and the rotating rod 3. The transmission mechanism 7 includes a first transmission member provided on the shaft section 32 and a second transmission member provided on the driving assembly 2 and cooperating with the first transmission member. Since the utility model aims to realize that the driving assembly 2 changes the transmission direction through the transmission mechanism 7 and drives the rotating rod 3 to rotate, that is, the rotation direction of the second transmission member driven by the driving assembly 2 is perpendicular or inclined to the rotation direction of the rotating rod 3 driven by the first driving member. Therefore, the transmission mechanism 7 can adopt a bevel gear set or a worm gear transmission mechanism.

[0035] In this embodiment, the transmission mechanism 7 adopts a bevel gear set. Specifically, the first transmission member is a first bevel gear 320 provided on the shaft section 32, and the second transmission member is a second bevel gear 330 provided on the drive assembly 2 and meshing with the first bevel gear 320. According to actual use needs, the angle between the first bevel gear 320 and the second bevel gear 330 can be adjusted, and can usually be selected to be 80°-100°.

[0036] The driving assembly 2 is used to transmit the power to the first bevel gear 320 through the second bevel gear 330, thereby driving the rotation of the rotating rod 3. The shaft section 32 of the rotating rod 3 is respectively sleeved with a first bearing 301 and a second bearing 302, which can effectively reduce friction and improve transmission efficiency. Of course, in order to simplify the structure and reduce costs, the first bearing 301 and the second bearing 302 can also directly use shaft sleeve elements.

[0037] Compared with the existing structure, only one transmission from the second bevel gear 330 to the first bevel gear 320 is required from the drive component 2 to the end of the bending section 31, thereby reducing the number of transmission times. In addition, the second bevel gear 330 and the first bevel gear 320 are bevel gear sets with higher transmission efficiency. Not only is the mechanical vibration generated inside very small, but the wear between the transmission components is also greatly reduced, and the service life is improved. In addition, the size of the outer shape is greatly reduced, the shape is regular, and the portability is good.

[0038] In addition, the utility model can further be provided with a second motor 40 in the housing 1, and an eccentric vibration block 41 is connected to the second motor 40. The eccentric vibration block 41 can be driven by the second motor 40 to rotate when the device is running, thereby driving the entire device to vibrate, thereby producing a vibration massage effect.

[0039] Combination Figure 2 As shown, the housing 1 includes a first housing 11 and a second housing 12 covering the first housing 11. A positioning portion 110 for limiting the shaft section 32 is formed in the first housing 11, and correspondingly, a pressing portion 120 matching the positioning portion 110 is formed on the second housing 12. By covering the second housing 12 on the first housing 11, the pressing portion 120 contacts and presses the positioning portion 110, and the pressing portion 120 and the positioning portion 110 jointly fix the rotating rod 3 to ensure the stability of the device during operation.

[0040] The first housing 11 is formed with a first receiving groove 51 for limiting the position of the drive assembly 2, and the first housing 11 is formed with a second receiving groove 52 for limiting the position of the second motor 40. The first receiving groove 51 is T-shaped and is used to limit the position of the drive assembly 2; the second receiving groove 52 is rectangular and is used to limit the position of the second motor 40.

[0041] The driving assembly 2 includes a first motor 210 and a reduction gear box 220 mounted on the first motor 210 , and the second bevel gear 330 is connected to the output shaft of the reduction gear box 220 .

[0042] The positioning portion 110 is formed with a first slot 111 and a second slot 112. The shaft section 32 is provided with a first bearing 301 and a second bearing 302 for reducing friction on both sides of the first bevel gear 320. The first bearing 301 is installed in the first slot 111, and the second bearing 302 is installed in the second slot 112. As mentioned above, the first bearing 301 and the second bearing 302 can also be directly made of sleeve elements. When installing, the two ends of the sleeve are directly installed in the first slot 111 and the second slot 112.

[0043] See Figure 3 and Figure 4 As shown, a plurality of first screw holes 10 are formed on the first shell 11 , and correspondingly, a plurality of positioning holes 60 are formed on the second shell 12 , and screws 61 are correspondingly provided in the plurality of positioning holes 60 , and the screws 61 pass through the positioning holes 60 and are screwedly installed in the first screw holes 10 .

[0044] See Figure 6 As shown, in the bevel gear set in this embodiment, the rotation center axis of the first bevel gear 320 is the shaft section 32, and the shaft section 32 is perpendicular to the rotation center axis of the second bevel gear 330. By setting the first bevel gear 320 and the second bevel gear 330 as bevel gears, vertical directional transmission between the first bevel gear 320 and the second bevel gear 330 is achieved.

[0045] In the second embodiment of the present utility model, see Figure 7 As shown, compared with the first embodiment, only the rotating rod 3 is different, and the rest of the structure is the same. The rotating rod 3 includes: an integrally formed bending section 31 and a shaft section 32, the bending section 31 extends out of the housing 1, and a massage head 316 is provided at the end of the bending section 31. The massage head 316 can be a bearing with an outer layer coated with silicone or rubber, so that the massage head 316 can rotate itself while rotating with the rotating rod 3.

[0046] In the third embodiment of the present invention, the transmission mechanism 7 is a worm gear structure, that is, the first transmission member is a worm gear disposed on the shaft body section 32, and the second transmission member is a turbine gear disposed on the drive assembly 2 and meshing with the worm gear. Specifically, the worm gear can be directly formed on the shaft body section 32, and the bending section 31 is formed by extending from one end of the worm gear. Compared with the first embodiment, the third embodiment is different only in the transmission mechanism 7, and the other structures are the same, which will not be described one by one here.

[0047] In summary, in the present invention, the driving assembly drives the rotating rod to rotate through the transmission mechanism, transmits the rotation through the transmission mechanism, and changes the rotation direction, so as to adjust the rotation direction within an effective space, and is suitable for various handheld massage devices. In addition, compared with the existing structure, the present invention can directly drive the rotating rod to rotate through a bevel gear set or a worm gear, which reduces the transmission level and improves the transmission efficiency. Not only is the mechanical vibration generated inside very small, but the wear between the transmission parts is also greatly reduced, and the service life is long.
