[0035] In order to enable those skilled in the art to better understand the implementation scheme of the present utility model, the technical scheme in the implementation scheme of the present utility model will be clearly and completely described below in conjunction with the drawings in the implementation scheme of the present utility model. Obviously, the described implementation scheme is only a part of the implementation scheme of the present utility model, not all of the implementation schemes. Based on the implementation scheme in the implementation scheme of the present utility model, all other implementation schemes obtained by those skilled in the art without making creative work are within the scope of protection of the implementation scheme of the present utility model.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Please also read Figure 1 and Figure 2 The embodiment of the utility model provides a compound motion motor 100, which includes a first driving mechanism 11 and a second driving mechanism 12. The first driving mechanism 11 has a first driving shaft 111, and the first driving mechanism 11 is suitable for driving the first driving shaft 111 to rotate or vibrate. In this way, the first driving mechanism 11 can meet the rotation or vibration requirements of the compound motion motor 100, so that the compound motion motor 100 can achieve rotational motion or vibration motion through the first driving mechanism 11.

[0038] In some embodiments, the first driving mechanism 11 may include a second frame 112 , a coil stator group 114 and a rotor group 115 , wherein the rotor group 115 is sleeved on the outer periphery of the first driving shaft 111 , and the coil stator group 114 is installed on the second frame 112 and surrounds the outer periphery of the rotor group 115 .

[0039] Thus, after the coil stator group 114 is energized, a magnetic field that changes with time is generated, which acts on the rotor group 115, thereby generating a torque that rotates the rotor group 115, thereby driving the first drive shaft 111 to rotate. The first drive mechanism 11 realizes rotation in a simple manner, which facilitates the manufacture of the first drive mechanism 11.

[0040] In addition, when the first driving mechanism 11 drives the first driving shaft 111 to move at a high frequency, the first driving shaft 111 can reciprocate along the length direction of the compound motion motor 100 , thereby outputting high-frequency vibration to the outside to achieve the vibration action of the first driving mechanism 11 .

[0041] In some embodiments, the first driving mechanism 11 and the second driving mechanism 12 are distributed along the length direction of the compound motion motor 100, and the second driving mechanism 12 has a driving end 121, which is connected to the first driving mechanism 11, and the driving end 121 is suitable for driving the first driving mechanism 11 to move along the length direction of the compound motion motor 100. In this way, the second driving mechanism 12 can meet the movement requirements of the compound motion motor 100, so that the compound motion motor 100 can achieve linear motion.

[0042] In addition, since the driving end 121 is connected to the first driving mechanism 11, the driving end 121 can drive the first driving mechanism 11 to synchronously perform linear motion, so that the compound motion motor 100 can synchronously achieve rotational motion and linear motion. In this way, the compound motion motor 100 can achieve rotational motion and / or linear motion, which helps to improve the diversity of the movement of the compound motion motor 100, thereby helping to meet the user's usage needs in different situations.

[0043] The driving end 121 being connected to the first driving mechanism 11 may refer to the driving end 121 being connected to the first driving shaft 111 , or may refer to the driving end 121 being connected to a partial structure of the first driving mechanism 11 , which may be specifically configured according to actual conditions.

[0044] The length direction of the compound motion motor 100 is arranged parallel to the axial direction of the first driving shaft 111 and the axial direction of the driving end 121 .

[0045] Please also read Figures 1 to 4 In some embodiments, the second driving mechanism 12 has a second driving shaft 1211, the driving end 121 is located on the second driving shaft 1211, and the first driving shaft 111 is connected to the second driving shaft 1211. In this way, the second driving shaft 1211 can drive the first driving shaft 111 to perform linear motion synchronously, so that the compound motion motor 100 can achieve rotational motion and linear motion synchronously.

[0046] In some embodiments, the second driving mechanism 12 may include a first frame 122, an electromagnetic coil group 123 and a magnetic core group 124, the magnetic core group 124 is sleeved on the outer periphery of the second driving shaft 1211, the electromagnetic coil group 123 is installed on the first frame 122 and surrounded by the outer periphery of the magnetic core group 124, the electromagnetic coil group 123 and the magnetic core group 124 are spaced apart, and the second driving shaft 1211 is suitable for driving the first driving shaft 111 to move along the length direction of the compound motion motor 100.

[0047] In this way, when the electromagnetic coil group 123 is energized, a magnetic field with alternating magnetic poles is formed by changing the direction of the current. The magnetic core group 124 is acted upon by the electromagnetic force in the magnetic field, driving the second drive shaft 1211 to move toward the first drive mechanism 11 or away from the first drive mechanism 11 along the length direction of the compound motion motor 100. Then, the second drive shaft 1211 can synchronously drive the first drive shaft 111 to move toward the first drive mechanism 11 along the length direction of the compound motion motor 100 to be in an extended state, as shown in FIG. Figure 3 or the second drive shaft 1211 can synchronously drive the first drive shaft 111 along the length direction of the compound motion motor 100 away from the first drive mechanism 11 to move in a retracted state, such as Figure 2 shown.

[0048] In some embodiments, the electromagnetic coil group 123 may be an annular coil, which is mounted on the first frame 122 and arranged around the outer periphery of the magnetic core group 124. The magnetic core group 124 may be an annular magnetic core, which is sleeved on the outer periphery of the driving end 121. In this way, the annular coil and the annular magnetic core help to simplify the structure of the second driving mechanism 12, facilitate manufacturing, save manufacturing costs, and also help to improve the compactness of the structure of the second driving mechanism 12.

[0049] The coil stator group 114 and rotor group 115 of the first drive mechanism 11 are spaced apart from the electromagnetic coil group 123 and magnetic core group 124 of the second drive mechanism 12, which helps to reduce the noise caused by the mutual interference between the structures of the first drive mechanism 11 and the second drive mechanism 12.

[0050] Among them, the first drive shaft 111 is connected to the second drive shaft 1211, which may mean that the first drive shaft 111 and the second drive shaft 1211 are an integrally formed structure; for example, the first drive shaft 111 is indirectly connected to the second drive shaft 1211, for example, the first drive shaft 111 can be connected to the second drive shaft 1211 through a retaining ring, a buffer structure, etc., and the specific settings can be made according to actual conditions.

[0051] In some embodiments, the first drive shaft 111 and the second drive shaft 1211 are integrally formed structures. For example, the first drive shaft 111 and the second drive shaft 1211 can be formed into a whole by an integral molding process. Figure 2 As shown, this helps to simplify the structure of the compound motion motor 100, helps to reduce the number of parts of the compound motion motor 100, and facilitates manufacturing.

[0052] See also Figure 5 In some embodiments, the compound motion motor 100 may include a buffer mechanism 16 , and two ends of the buffer mechanism 16 are respectively connected to the first driving shaft 111 and the second driving shaft 1211 .

[0053] In this way, the buffer mechanism 16 can provide a certain buffering effect for the first drive shaft 111, which helps to reduce the vibration transmitted to the second drive shaft 1211 during the rotational motion of the first drive shaft 111, thereby helping to reduce the resonance between the second drive shaft 1211 and the first drive shaft 111.

[0054] In some embodiments, the buffer mechanism 16 includes a spring 161, and both ends of the spring 161 are respectively connected to the first drive shaft 111 and the second drive shaft 1211. Figure 5 Alternatively, the buffer mechanism 16 includes a spring 162, the ends of which are respectively connected to the first drive shaft 111 and the second drive shaft 1211, as shown Figure 6 As shown; or, the buffer mechanism 16 includes a first buffer table 164, a second buffer table 165 and at least one buffer column 163, the two ends of the buffer column 163 are respectively connected to the first buffer table 164 and the second buffer table 165, the first buffer table 164 is connected to the first drive shaft 111, and the second buffer table 165 is connected to the second drive shaft 1211, as shown Figure 7 shown.

[0055] For example, Figure 5As shown, the buffer mechanism 16 may include a spring 161, and both ends of the spring 161 are respectively connected to the first drive shaft 111 and the second drive shaft 1211. The spring 161 can absorb the vibration and impact energy of the first drive shaft 111, thereby helping to reduce the vibration and impact energy transmitted from the first drive shaft 111 to the second drive shaft 1211, and helping to reduce the situation where the second drive shaft 1211 is disturbed by the vibration of the first drive shaft 111.

[0056] One end of the spring 161 is clamped on the outer periphery of the first drive shaft 111 through an annular retaining spring, and the other end of the spring 161 is clamped on the outer periphery of the second drive shaft 1211 through an annular retaining spring. This helps to improve the stability of the spring 161 connected to the first drive shaft 111 and the second drive shaft 1211, and helps to reduce the risk of the spring 161 being loosened from the first drive shaft 111 and the second drive shaft 1211.

[0057] For example, Figure 6 As shown, the buffer mechanism 16 may include a spring sheet 162, and the two ends of the spring sheet 162 are respectively connected to the first drive shaft 111 and the second drive shaft 1211. The spring sheet 162 can absorb the vibration and impact energy of the first drive shaft 111, thereby helping to reduce the vibration and impact energy transmitted from the first drive shaft 111 to the second drive shaft 1211, and helping to reduce the situation where the second drive shaft 1211 is disturbed by the vibration of the first drive shaft 111.

[0058] Wherein, the two ends of the spring sheet 162 may be provided with a spring sheet respectively, the first drive shaft 111 and the second drive shaft 1211 may be provided with a slot, the spring sheet at one end of the spring sheet 162 is clamped in the slot of the first drive shaft 111 to achieve the connection between one end of the spring sheet 162 and the first drive shaft 111, and the spring sheet at the other end of the spring sheet 162 is clamped in the slot of the second drive shaft 1211 to achieve the connection between the other end of the spring sheet 162 and the second drive shaft 1211. In this way, it is helpful to improve the stability of the spring sheet 162 connected to the first drive shaft 111 and the second drive shaft 1211, and it is helpful to reduce the risk of the spring sheet 162 being loosened from the first drive shaft 111 and the second drive shaft 1211.

[0059] For example, Figure 7As shown, the buffer mechanism 16 may include a first buffer platform 164, a second buffer platform 165 and at least one buffer column 163. The first buffer platform 164, the second buffer platform 165 and the buffer column 163 may all be made of hardware structures such as stainless steel to improve the rigidity of the buffer structure 16. The two ends of the buffer column 163 are respectively connected to the first buffer platform 164 and the second buffer platform 165. The first buffer platform 164 is connected to the first drive shaft 111, and the second buffer platform 165 is connected to the second drive shaft 1211. In this way, it is helpful to reduce the situation where the vibration and impact energy of the first drive shaft 111 are directly transmitted to the second drive shaft 1211, and it is also helpful to form a rigid connection between the first drive shaft 111 and the second drive shaft 1211, thereby providing the telescopic power of the first drive shaft 111 and the second drive shaft 1211.

[0060] The buffer mechanism 16 may include one, two, three, four, five or other number of buffer columns 163 , which may be specifically configured according to actual conditions.

[0061] In other embodiments, the buffer mechanism 16 may further include other components, which may be specifically configured according to actual conditions, as long as the buffer mechanism 16 can provide a buffering effect for the first drive shaft 111 .

[0062] Please also read Figures 8 to 10 In some embodiments, the second driving mechanism 12 may include a driving member 125 and a sliding assembly 126. For example, the driving member 125 may be a servo motor. The driving end 121 is located at the sliding assembly 126. The sliding assembly 126 is connected to the driving member 125 and the first driving mechanism 11. The driving member 125 is suitable for driving the sliding assembly 126 to move along the length direction of the compound motion motor 100. The movement of the sliding assembly 126 along the length direction of the compound motion motor 100 is suitable for driving the first driving mechanism 11 to move along the length direction of the compound motion motor 100. For example, the driving member 125 may drive the sliding assembly 126 to move toward the driving member 125 along the length direction of the compound motion motor 100, so that the first driving mechanism 11 may move toward the driving member 125 along the length direction of the compound motion motor 100, or the driving member 125 may drive the sliding assembly 126 to move away from the driving member 125 along the length direction of the compound motion motor 100, so that the first driving mechanism 11 may move away from the driving member 125 along the length direction of the compound motion motor 100.

[0063] In this way, the compound motion motor 100 can drive the first driving mechanism 11 to synchronously perform linear motion through the driving member 125 and the sliding assembly 126, so that the compound motion motor 100 can achieve rotational motion and linear motion. The driving member 125 drives the sliding assembly 126 to move along the length direction of the compound motion motor 100 in a simple manner, which helps to simplify the structure of the compound motion motor 100 and facilitates the manufacture of the compound motion motor 100.

[0064] Please also read Figures 8 to 10 In some embodiments, the sliding assembly 126 may include a sliding member 1261 and a cam 1262, the driving end 121 is located on the sliding member 1261, the sliding member 1261 is connected to the first driving mechanism 11, the cam 1262 is connected to the driving member 125, a sliding body 1263 is provided on the side of the sliding member 1261 facing the cam 1262, a sliding groove 1264 is provided on the side of the cam 1262 facing the sliding member 1261, the sliding groove 1264 extends obliquely relative to the length direction of the compound motion motor 100, the sliding body 1263 is slidably located in the sliding groove 1264, the driving member 125 is suitable for driving the cam 1262 to rotate, and the rotation of the cam 1262 is suitable for driving the sliding member 1261 to move along the length direction of the compound motion motor 100.

[0065] Thus, the second drive mechanism 12 can convert the rotational motion of the cam 1262 into the linear motion of the slide 1261 through the cooperation between the slide body 1263 and the slide slot 1264, thereby helping to ensure the normal operation of the second drive mechanism 12. The second drive mechanism 12 has a simple structure and is easy to manufacture.

[0066] For example, the driving member 125 can be controlled to rotate forwardly so that the cam 1262 and the driving member 125 rotate forwardly synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the forward rotation of the cam 1262 drives the sliding member 1261 to move toward the driving member 125 along the length direction of the compound motion motor 100, so that the first driving mechanism 11 connected to the sliding member 1261 can synchronously move toward the driving member 125 along the length direction of the compound motion motor 100, so that the first driving shaft 111 is in a retracted state (such as Figure 8 shown).

[0067] For another example, the driving member 125 can be controlled to reverse so that the cam 1262 and the driving member 125 reverse synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the reverse rotation of the cam 1262 drives the sliding member 1261 to move away from the driving member 125 along the length direction of the compound motion motor 100, so that the first driving mechanism 11 connected to the sliding member 1261 can synchronously move away from the driving member 125 along the length direction of the compound motion motor 100, so that the first driving shaft 111 is in an extended state (such as Fig. 9shown).

[0068] In some embodiments, the slide groove 1264 can also be set to a ring structure connected end to end. In this case, the sliding body 1263 can slide a full circle in the slide groove 1264, and the first drive shaft 111 can be repeatedly switched between the retracted state and the extended state by controlling the driving member 125 to rotate forward or reverse.

[0069] In some embodiments, the sliding member 1261 is disposed around the outer periphery of the cam 1262 and connected to the first driving shaft 111 , and the movement of the sliding member 1261 along the length direction of the compound motion motor 100 is suitable for driving the first driving shaft 111 to move along the length direction of the compound motion motor 100 .

[0070] In this way, the driving member 125 can drive the sliding member 1261 to move to drive the first driving shaft 111 to move along the length direction of the compound motion motor 100, and the second driving mechanism 12 can be only connected to the driving shaft 111 of the first driving mechanism 11, which helps to reduce the load of the first driving mechanism 11 connected to the second driving mechanism 12, thereby helping to reduce the load of the driving member 125 and helping to increase the service life of the driving member 125.

[0071] Exemplarily, the driving member 125 can be controlled to rotate forward so that the cam 1262 and the driving member 125 can rotate forward synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the forward rotation of the cam 1262 will drive the sliding member 1261 to move toward the driving member 125 along the length direction of the compound motion motor 100, so that the first driving shaft 111 connected to the sliding member 1261 can move toward the driving member 125 synchronously along the length direction of the compound motion motor 100.

[0072] For another example, the driving member 125 can be controlled to reverse so that the cam 1262 and the driving member 125 reverse synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the reversal of the cam 1262 will drive the sliding member 1261 to move away from the driving member 125 along the length direction of the compound motion motor 100, so that the first driving shaft 111 connected to the sliding member 1261 can synchronously move away from the driving member 125 along the length direction of the compound motion motor 100.

[0073] See also Figure 11 to Figure 12 In some embodiments, the first driving shaft 111 is located in the second frame 112, the sliding member 1261 is arranged around the cam 1262 and the outer periphery of the second frame 112 and is connected to the second frame 112, and the movement of the sliding member 1261 along the length direction of the compound motion motor 100 is suitable for driving the second frame 112 to move along the length direction of the compound motion motor 100.

[0074] In this way, the driving member 125 can drive the sliding member 1261 to move so as to drive the second frame 112 to move along the length direction of the compound motion motor 100. At this time, the first driving shaft 111 will move synchronously with the second frame 112 along the length direction of the compound motion motor 100. The second driving mechanism 12 is connected to the second frame 112 so that the second driving mechanism 12 is not directly connected to the first driving shaft 111, which helps to reduce the vibration generated by the rotational movement of the first driving shaft 111 from being transmitted to the second driving mechanism 12, thereby helping to reduce the resonance between the second driving mechanism 12 and the first driving shaft 111.

[0075] For example, the driving member 125 can be controlled to rotate forwardly so that the cam 1262 and the driving member 125 rotate forwardly synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the forward rotation of the cam 1262 drives the sliding member 1261 to move toward the driving member 125 along the length direction of the compound motion motor 100, so that the second frame 112 connected to the sliding member 1261 can synchronously move toward the driving member 125 along the length direction of the compound motion motor 100, so that the first driving shaft 111 is in a retracted state (such as Fig.11 shown).

[0076] For another example, the driving member 125 can be controlled to reverse so that the cam 1262 and the driving member 125 reverse synchronously. At this time, the sliding body 1263 slides in the sliding groove 1264, and the reversal of the cam 1262 will drive the sliding member 1261 to move away from the driving member 125 along the length direction of the compound motion motor 100, so that the second frame 112 connected to the sliding member 1261 can synchronously move away from the driving member 125 along the length direction of the compound motion motor 100, thereby making the first driving shaft 111 in an extended state.

[0077] See also Fig.13 and Fig.14 In some embodiments, the second driving mechanism 12 has a second driving shaft 1211, and the driving end 121 is located at the second driving shaft 1211. The second driving mechanism 12 may also include a first connecting member 1265 and a second connecting member 1266, and the first connecting member 1265 and the second connecting member 1266 are threadedly matched. The second driving shaft 1211 is connected to the first driving shaft 111 and the end of the second connecting member 1266 away from the first connecting member 1265. The driving member 125 is connected to the end of the first connecting member 1265 away from the second connecting member 1266 and is suitable for driving the first connecting member 1265 to rotate. The rotation of the first connecting member 1265 is suitable for driving the second connecting member 1266 and the second driving shaft 1211 to move along the length direction of the compound motion motor 100. The movement of the second driving shaft 1211 along the length direction of the compound motion motor 100 is suitable for driving the first driving shaft 111 to move along the length direction of the compound motion motor 100.

[0078] In this way, the second drive mechanism 12 can convert the rotational motion of the first connection member 1265 into the linear motion of the second connection member 1266 through the screw transmission of the first connection member 1265 and the second connection member 1266, so that the second drive shaft 1211 can perform linear motion synchronously with the second connection member 1266, thereby helping to ensure the normal operation of the second drive mechanism 12. The second drive mechanism 12 has a simple structure, which helps to facilitate manufacturing.

[0079] Exemplarily, the driving member 125 can be controlled to rotate forward synchronously with the driving member 125. At this time, the first connecting member 1265 and the second connecting member 1266 are threadedly matched. The forward rotation of the first connecting member 1265 will drive the second connecting member 1266 and the second drive shaft 1211 to move away from the first connecting member 1265 along the length direction of the compound motion motor 100, so that the first drive shaft 111 connected to the second drive shaft 1211 can be synchronously moved away from the first connecting member 1265 along the length direction of the compound motion motor 100, so that the first drive shaft 111 is in an extended state.

[0080] For another example, the driving member 125 can be controlled to reverse so that the first connecting member 1265 and the driving member 125 reverse synchronously. At this time, the first connecting member 1265 and the second connecting member 1266 are threadedly matched. The reversal of the first connecting member 1265 will drive the second connecting member 1266 and the second drive shaft 1211 to move toward the first connecting member 1265 along the length direction of the compound motion motor 100, so that the first drive shaft 111 connected to the first connecting member 1265 can be synchronously moved along the length direction of the compound motion motor 100 toward the first connecting member 1265, so that the first drive shaft 111 is in a retracted state.

[0081] Re-read Figure 2 and Figure 8 and Fig.13 In some embodiments, the compound motion motor 100 may further include a first universal bearing 14 and a second universal bearing 15. For example, the first universal bearing 14 and the second universal bearing 15 may both be rolling bearings. The first universal bearing 14 and the second universal bearing 15 are respectively sleeved at two opposite ends of the first drive shaft 111 in the axial direction.

[0082] In this way, the first universal bearing 14 and the second universal bearing 15 can meet the rotation and movement requirements of the first drive shaft 111, and also help reduce the friction between the second frame 112 and the first drive shaft 111 when the first drive shaft 111 rotates and moves, thereby helping to improve the smoothness of the operation of the compound motion motor 100.

[0083] For example, Figure 2As shown, the first universal bearing 14 can be located on the side of the first drive shaft 111 axially away from the second drive shaft 1211, and the second universal bearing 15 can be located at the connection between the first drive shaft 111 and the second drive shaft 1211; for example, Figure 8 As shown, the first universal bearing 14 can be located on the axial side of the first drive shaft 111 away from the sliding member 1261, and the second universal bearing 15 can be located on the axial side of the first drive shaft 111 and connected to the sliding member 1261; for example, Fig.13 As shown, the first universal bearing 14 can be located on the side of the first drive shaft 111 axially away from the second drive shaft 1211, and the second universal bearing 15 can be located on the side of the first drive shaft 111 axially facing the second drive shaft 1211, which can be specifically arranged according to actual conditions.

In this way, when the oral cleaning device 1000 is working, the first drive mechanism 11 of the compound motion motor 100 can drive the first drive shaft 111 to rotate repeatedly and alternately clockwise and counterclockwise along the length direction of the compound motion motor 100 at a high frequency, thereby generating a circumferential vibration effect, and the second drive mechanism 12 can drive the first drive shaft 111 to rotate repeatedly and alternately along the first drive mechanism 11 at a high frequency, thereby generating an axial vibration effect, thereby ensuring the normal operation of the cleaning body 200.

[0086] For example, when the oral cleaning device 1000 is an electric toothbrush, the cleaning body 200 can be a toothbrush head, and the toothbrush head is connected to the first drive shaft 111. When the electric toothbrush is working, the first drive shaft 111 can drive the toothbrush head to perform circumferential and axial composite vibrations to achieve all-round cleaning of the teeth.

[0087] In summary, the compound motion motor 100 and the oral cleaning device 1000 provided by the embodiment of the utility model, the first driving mechanism 11 of the compound motion motor 100 has a first driving shaft 111, and the first driving mechanism 11 is suitable for driving the first driving shaft 111 to rotate or vibrate, so the first driving mechanism 11 can meet the rotation or vibration requirements of the compound motion motor 100. The second driving mechanism 12 of the compound motion motor 100 has a driving end 121, and the driving end 121 is connected to the first driving mechanism 11, and the driving end 121 is suitable for driving the first driving mechanism 11 to move along the length direction of the compound motion motor 100, so the second driving mechanism 12 can meet the movement requirements of the compound motion motor 100. In this way, the compound motion motor 100 can realize the functions of rotation and / or movement, which helps to improve the diversity of the movement of the compound motion motor 100, thereby helping to improve the diversity of the movement of the oral cleaning device 1000, and helping to meet the use requirements of users in different situations.
