Technical Field

[0001] The present application relates to the field of movement technology, and in particular to a movement driven by a double-head motor. Background Art

[0002] The existing pulse beat function movement uses the Hall electromagnetic effect to drive the internal electromagnet to do reciprocating motion. This implementation method has high material costs and requires customization, which is not conducive to cost control, and is accompanied by the disadvantage of rapid temperature rise.

[0003] The Chinese patent with the publication number CN200920264225.2 discloses a pulse drive device for the pressure limiting valve of an electric pressure cooker, which is special in that it includes a bracket, a lever, an iron core and an electromagnetic coil; the lever is pivotally connected to the bracket, one end of the lever cooperates with the pressure limiting valve, and the iron core arranged on the lever cooperates with the ring. Due to the use of such a structure, according to the cooking requirements, the power switch of the electromagnetic coil is turned on in time, and the control device of the electric pressure cooker provides current to the electromagnetic coil. The change of the inductance of the electromagnetic coil attracts the iron core, thereby driving the pressure limiting valve with the lever; the pressure limiting valve pulses and the lever reciprocates, so it can drive the pressure limiting valve to operate according to the cooking requirements, release the pressure, and prevent the phenomenon of excessive pressure and boiling pot. This technical solution adopts the electromagnetic coil structure, which is relatively costly.

[0004] The movement is an important structure of the massager. Existing massagers are limited by the mechanical structure and can only provide continuous massage at a constant force of different gears. It is difficult to obtain a comfortable massage effect, and the massage process is relatively boring. The noise accompanied by the mechanical structure makes it difficult to truly relax the body and mind, and the user's massage experience is poor.

[0008] According to an embodiment of the present application, the motor gear is a cylindrical gear fixed on the output shaft of the first output end of the motor, and the transmission assembly includes a crown cylindrical gear, the tooth end of the crown cylindrical gear faces upward to the first cover body and meshes with the cylindrical gear, and a pin hole is provided in the center of the crown cylindrical gear, and the pin shaft passes through the pin hole and is connected to the inner side of the first cover body to fix the crown cylindrical gear.

[0009] According to an embodiment of the present application, a boss facing the second cover body is provided on the ground of the crown-shaped cylindrical gear, a pulley or a rotating ball is provided at the bottom of the boss, and a long groove for the boss to pass through is provided on the inner side of the second cover body along the width direction.

[0010] According to an embodiment of the present application, the vibration component includes an eccentric block, which is connected to the output shaft of the second output end of the double-headed motor. The eccentric block is connected to the massage component outside the outer shell. When the double-headed motor drives the eccentric block to rotate, the massage component generates a vibration effect as the eccentric block rotates.

[0011] According to an embodiment of the present application, the vibration component includes a vibrator and a main shaft through which the vibrator is passed. One end of the main shaft is connected to the output shaft of the second output end of the double-headed motor. The output shaft is used to drive the main shaft to rotate around its central axis and drive the vibrator to vibrate along the axial direction of the main shaft. The other end of the main shaft is connected to the massage component outside the shell.

[0012] According to an embodiment of the present application, a screw hole is provided on the first cover body, and a corresponding threaded hole is provided on the second cover body. The screw passes through the screw hole and is tightened with the threaded hole to achieve a fixed connection between the first cover body and the second cover body.

[0013] According to an embodiment of the present application, the outer shell is composed of a first shell and a second shell, and a sliding groove for the projection to slide is provided inside the second shell close to the second cover.

[0014] According to an embodiment of the present application, the first shell and the second shell are connected by tightening with screws, and the inner walls of the first shell and the second shell are provided with reinforcing ribs.

[0015] According to an embodiment of the present application, the motor is electrically connected to a circuit control board, and the circuit control board is connected to a power supply structure.

[0016] According to an embodiment of the present application, one end of the shell opening is detachably connected to a massage part for massage.

[0017] Compared with the prior art, the movement of the present application has the following beneficial effects:

[0018] 1. This application uses gear meshing, and the sound is very small if it is well lubricated, so the noise is small, the use is more comfortable, and the movement is more durable.

[0019] 2. The movement of this application can replace the outer shell as needed to meet various needs such as usage and appearance.

[0020] 3. The massage part connected to the vibration mechanism of the movement of the present application can have various combinations, can be applicable to various massagers, and has wide market applications.

[0021] 4. The present application has a simple structure and adopts a double-headed motor.

No complex control mechanism is required to synchronize the vibration frequency and the pulse frequency to achieve a good movement effect, so that the movement has both pulse beating and vibration functions, and has high practical value.

[0022] 5. The design of the present application is ingenious. When the double-headed motor is working, the motor gear rotates, and the crown-shaped cylindrical gear meshing with it is also driven to rotate. The eccentric boss at the bottom of the crown-shaped cylindrical gear rotates with the crown-shaped cylindrical gear, but the boss is stuck in the slide groove of the outer shell. The slide groove limits the movement trajectory of the boss. At the same time, the pin shaft in the center of the crown-shaped cylindrical gear is fixed in the machine cover and does not move. Therefore, when the motor rotates, the entire assembly wrapped by the machine cover will make reciprocating motion left and right in the outer shell, thereby driving the entire movement to achieve a pulse beating effect. Compared with the existing electromagnetic pulse effect, it not only has a low production cost, but also has a stable and controllable frequency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figures 1 to 3 As shown, a movement driven by a double-headed motor 104 of the present application includes a machine cover, a double-headed motor 104, a pulse device, a vibration device and a shell, wherein the double-headed motor 104, the pulse device and the vibration device are all arranged in the machine cover to form the inner part of the movement, and the shell wraps the entire machine cover, with one end closed and the other end open, and the open end can be installed on a matching corresponding device.

[0044] The corresponding device can be a massage part, the open end of the shell is connected to the massage part, the shell wraps the inner part of the entire movement, the pulse device can make the movement produce a pulse beating effect, and the vibration device can make the movement produce a vibration massage effect. These two effects are produced at the same time, the massage effect is more obvious, and the massage of the human body is more concentrated.

[0045] like Figure 1 As shown, the machine cover includes a first cover body 106 and a second cover body 107 which are aligned and spliced ​​to form the machine cover.

[0046] Furthermore, a screw hole is provided on the first cover 106, and a corresponding threaded hole is provided on the second cover 107. The screw 110 passes through the screw hole and is tightened with the threaded hole to achieve a fixed connection between the first cover 106 and the second cover 107. The present application does not limit the connection method of the first cover 106 and the second cover 107, and a commonly used connection method in the technical field can be adopted.

[0047] The double-headed motor 104 is located in a chamber formed by the first cover 106 and the second cover 107, and can be fixed in a motor fixing base provided in the second cover 107. The double-headed motor 104 includes a first output end and a second output end, and the first output shaft is connected to a motor gear.

[0048] Furthermore, the motor gear 103 is a cylindrical gear fixed on the output shaft of the first output end of the motor.

[0049] Furthermore, the double-headed motor 104 is preferably a motor with adjustable frequency.

[0050] Furthermore, the motor is electrically connected to a circuit control board, and the circuit control board is connected to a power supply structure. The circuit control board is provided with a control key for controlling the on-off between the power supply structure and the circuit control board. The power supply structure may include a lithium battery and a dry cell battery that are independent of each other, and the two are respectively connected to the circuit control board to form a structure that can be powered independently or together. Through the mixed power supply of lithium batteries and dry cells, the movement can be supported by the lithium battery or by the dry cell battery. When the user feels that the working force is not enough, the lithium battery and the dry cell battery can be turned on to work simultaneously to enhance the working force of the function.

[0051] The pulse device includes a transmission assembly meshed with the motor gear 103, and a first end of the transmission assembly is connected to the first cover body 106. The transmission assembly may include a crown-shaped cylindrical gear 108, the tooth end of the crown-shaped cylindrical gear 108 faces upward to the first cover body 106 and meshes with the cylindrical gear, and a pin hole is provided at the center of the crown-shaped cylindrical gear 108, and the pin shaft 102 passes through the pin hole and is connected to the inner side of the first cover body 106 to fix the crown-shaped cylindrical gear 108.

[0052] Furthermore, if Figures 1 to 3As shown, the bottom surface of the crown cylindrical gear 108 is provided with a boss 111 facing the second cover body 107, and the bottom of the boss 111 is fixedly connected with a pulley or a rotating bead, and the inner side of the second cover body 107 is provided with a long groove for the boss 111 to pass through along the width direction. The boss 111 passes through the long groove, and the bottom of the boss 111 is placed in the slide groove 112 provided inside the shell. The slide groove 112 is set along the arc of the bottom of the shell, and the size is adapted to the bottom of the boss 111. When the boss 111 moves, the slide groove 112 can limit the position and direction of its movement. When the double-headed motor 104 drives the motor gear 103 to rotate, it drives the crown cylindrical gear 108 to rotate, and the boss 111 at its bottom edge moves together with the crown cylindrical gear 108. Since the bottom of the boss 111 is set in the slide groove 112, it can drive the entire cover-wrapped device to move along the slide groove 112, and the cover component can make left and right reciprocating movements relative to the shell.

[0053] Furthermore, a pulley or a rotating ball may be fixedly provided at the bottom of the protruding column 111 , and the pulley or the rotating ball may slide freely in the sliding groove 112 along the sliding groove 112 .

[0054] The vibration device includes a vibration component connected to the second output end of the double-headed motor 104.

[0055] Furthermore, if Figure 1 As shown, the vibration component may include an eccentric block 105, which is connected to the output shaft of the second output end of the double-headed motor 104. The eccentric block 105 is connected to the massage component outside the shell. When the double-headed motor 104 drives the eccentric block 105 to rotate, the massage component generates a rotational vibration effect as the eccentric block 105 rotates.

[0056] Furthermore, the vibration component includes a vibrator and a main shaft through which the vibrator is installed. One end of the main shaft is connected to the output shaft of the second output end of the double-headed motor 104. The output shaft is used to drive the main shaft to rotate around its center and drive the vibrator to vibrate along the axial direction of the main shaft. The other end of the main shaft can be connected to the massage component outside the shell.

[0057] The shell wraps the whole machine cover and its internal devices. One end of the shell is closed and the other end is open. The open end is used to connect the working parts.

[0058] Furthermore, the housing may be composed of a first housing 101 and a second housing 109 , and a sliding groove 112 for the protruding column 111 to slide is provided inside the second housing 109 close to the second cover 107 .

[0059] Furthermore, the first shell 101 and the second shell 109 are connected by screws, and the two can be detachably connected, which is convenient for maintenance and cleaning. The inner walls of the first shell 101 and the second shell 109 are provided with reinforcing ribs.

[0060] Working principle: When the double-headed motor 104 is working, one end drives the motor gear 103 to rotate, and the motor gear 103 drives the crown-shaped cylindrical gear 108 to rotate. The rotation of the crown-shaped cylindrical gear 108 causes the convex column 111 fixed at the bottom thereof to rotate. However, since the pin 102 on the crown-shaped cylindrical gear 108 is fixed in the cover, the convex column 111 inserted into the slide groove 112 can move along the slide groove 112, thereby driving the inner liner part wrapped by the entire cover to move along the arc surface where the slide groove 112 is located, that is, the cover as a whole reciprocates left and right relative to the shell; at the same time, the output shaft of the other end of the double-headed motor 104 drives the eccentric block 105 to rotate, and the vibration massage effect of the movement is achieved through the rotation of the eccentric block 105. In this way, the movement has both pulse beating and vibration functions.

[0061] The corresponding device connected to the movement can be a variety of massage components. The outer shell of the movement can be provided with a massage part for massaging the human body. The massage part can be provided on the upper surface of the outer shell and provided in a plurality. Each massage part can be provided in different sizes. When the outer shell vibrates, it drives each massage part provided on the upper surface of the outer shell to vibrate together, and utilizes the vibration of the massage part to massage the human body. Since each massage part has different shapes and sizes, the vibration effect of each massage part is different, so that the massage strength on the human body is different, that is, the larger the massage part, the smaller the massage strength on the human body; the smaller the massage part, the greater the massage strength on the human body. In actual operation, different strengths are applied to different acupoints to achieve appropriate massage strengths, so as to obtain a better massage experience.

[0062] In summary, the double-head motor-driven movement of the present application has the following beneficial effects:

[0063] 1. This application uses gear meshing, and the sound is very small if it is well lubricated, so the noise is small, the use is more comfortable, and the movement is more durable.

[0064] 2. The movement of this application can replace the outer shell as needed to meet various needs such as usage and appearance.

[0065] 3. The massage part connected to the vibration mechanism of the movement of the present application can have various combinations, can be applicable to various massagers, and has wide market applications.

[0066] 4. The present application has a simple structure and adopts a double-headed motor. One end of the motor is connected to the vibration component, and the other end is connected to the component that produces the pulse beating effect. The controller is connected to the motor. No complex control mechanism is required to synchronize the vibration frequency and the pulse frequency to achieve a good movement effect, so that the movement has both pulse beating and vibration functions, and has high practical value.

[0067] 5. The design of the present application is ingenious. When the double-headed motor is working, the motor gear rotates, and the crown-shaped cylindrical gear meshing with it is also driven to rotate. The eccentric boss at the bottom of the crown-shaped cylindrical gear rotates with the crown-shaped cylindrical gear, but the boss is stuck in the slide groove of the outer shell. The slide groove limits the movement trajectory of the boss. At the same time, the pin shaft in the center of the crown-shaped cylindrical gear is fixed in the machine cover and does not move. Therefore, when the motor rotates, the entire assembly wrapped by the machine cover will make reciprocating motion left and right in the outer shell, thereby driving the entire movement to achieve a pulse beating effect. Compared with the existing electromagnetic pulse effect, it not only has a low production cost, but also has a stable and controllable frequency.
