[0032] For the convenience of those skilled in the art to understand, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation mode is not a limitation to the present invention.

[0033] Please refer to Figures 1 to 5 As shown, a multifunctional vibration device of the present invention includes a chassis 1, a first motor 2 and a first transmission mechanism 3 installed on the chassis 1, a carrier 4 movably arranged on the chassis 1, a second motor 5 and a second transmission mechanism 6 arranged on the carrier 4, and a support frame 7 movably arranged on the second transmission mechanism 6. The chassis 1 is used to be placed on the ground. Preferably, the chassis 1 is generally a rectangular frame, and lifting support discs are respectively provided at the four corners of the bottom of the chassis 1. The lifting support discs are used to stably place the chassis 1 on the ground, and the lifting support discs can be screwed to the chassis 1. In actual use, the first motor 2 drives the carrier 4 to vibrate horizontally back and forth through the first transmission mechanism 3. The horizontally reciprocating vibrating carrier 4 drives the support frame 7 to vibrate horizontally back and forth together. The second motor 5 drives the support frame 7 to vibrate up and down through the second transmission mechanism 6. The lifting support discs are configured with soft pads pressed on the ground. Through the setting of the soft pads, the impact on the ground during the vibration of the vibration device is reduced.

[0034] Of course, according to actual needs, the first motor 2 can be used to drive the carrier 4 together with the support frame 7 to vibrate horizontally back and forth through the first transmission mechanism 3, and only the horizontal vibration mode is started; or the second motor 5 can be used to drive the support frame 7 to vibrate up and down through the second transmission mechanism 6, and only the vertical vibration mode is started; or horizontal reciprocating vibration and up and down vibration can be carried out simultaneously to improve the diversity of the vibration modes of the vibration device.

[0035] A first shaft body 8 is rotatably arranged on the chassis 1. The first shaft body 8 is configured with a first eccentric wheel 9. The first transmission mechanism 3 includes a first plate member 11, a second plate member 12, a third plate member 13 and a first brace member 14. One end of the first plate member 11 is rotatably sleeved outside the first eccentric wheel 9. The other end of the first plate member 11 is rotatably arranged with one end of the second plate member 12. The lower end of the first brace member 14 is fixedly arranged on the chassis 1. The middle part of the second plate member 12 is rotatably arranged on the upper end of the first brace member 14. The other end of the second plate member 12 is rotatably arranged with one end of the third plate member 13. The other end of the third plate member 13 is rotatably arranged on the carrier 4.

[0036] When the first motor 2 drives the carrier 4 to vibrate horizontally back and forth via the first transmission mechanism 3, the first plate 11, the second plate 12, and the third plate 13 are used to realize continuous decomposition of the horizontal movement stroke of the carrier 4, so as to prevent the carrier 4 from moving too far at one time, and enable the carrier 4 to move in small distances in sequence, thereby ensuring the stability of the vibration, improving the consumer experience, and avoiding excessive vibration of the carrier 4 and causing a poor experience.

[0037] In this embodiment, the first shaft body 8 and the first eccentric wheel 9 are integrally constructed, and the central axis of the first shaft body 8 and the central axis of the first eccentric wheel 9 are spaced apart and arranged in parallel. The first shaft body 8 and the first eccentric wheel 9 do not need to be assembled with each other, which improves the installation efficiency or disassembly efficiency on the one hand, and avoids the vibration caused by the installation error of the first eccentric wheel 9 on the other hand.

[0038] The first eccentric wheel 9 is sleeved with a first bearing 15 on its outer side, and one end of the first plate 11 is sleeved on the outer side of the first bearing 15. The first bearing 15 is provided to reduce the wear between the first eccentric wheel 9 and the first plate 11, extend the service life, and reduce the friction noise between the two.

[0039] Two support units 16 are provided on the base frame 1, and guide rods 17 are provided at both ends of the carrier 4 for use with the two support units 16 respectively. The support unit 16 has three rotatable guide wheels 18, and the rotation axes of the guide wheels 18 are parallel to the horizontal plane. One guide wheel 18 is located above the guide rod 17, and two guide wheels 18 are located below the guide rod 17. The guide wheel 18 above the guide rod 17 is located between the two guide wheels 18 below the guide rod 17, and the guide rod 17 is clamped between the guide wheels 18 arranged above and below.

[0040] The guide wheel 18 is provided with a first annular groove 19 , which is arranged around the rotation axis of the guide wheel 18 , and the guide rod 17 is accommodated in the first annular groove 19 of the guide wheel 18 .

[0041] Through the arrangement of the support unit 16, the carrier 4 is rolled with the base frame 1 via the guide wheel 18. When the first motor 2 drives the carrier 4 and the support frame 7 to vibrate horizontally back and forth via the first transmission mechanism 3, the wear between the carrier 4 and the base frame 1 is reduced. Through the arrangement of the first annular groove 19, the inner groove wall of the first annular groove 19 is used to block and abut the guide rod 17 to prevent the guide rod 17 from falling off the guide wheel 18. Preferably, the number of the support units 16 is four, and the same end of the carrier 4 is movably arranged with the base frame 1 via two support units 16, and the two support units 16 at the same end of the carrier 4 are respectively located on both sides of the carrier 4 away from each other. Of course, according to actual needs, the number of the support units 16 can also be six, seven or eight.

[0042] The first motor 2 drives the first shaft body 8 to rotate via a belt drive mechanism. The belt drive mechanism includes a first pulley 21 installed on the output shaft of the first motor 2, a second pulley 22 installed on the first shaft body 8, and an endless belt 23 sleeved outside the first pulley 21 and the second pulley 22.

[0043] The pulley is provided with a second annular groove, which is arranged around the rotation axis of the pulley. The endless belt 23 is provided with annular ribs extending along the length direction of the endless belt 23. The inner groove wall of the second annular groove abuts against the annular ribs. By means of the abutment of the inner groove wall of the second annular groove against the annular ribs, the endless belt 23 is prevented from falling off the pulley, ensuring that the endless belt 23 is firmly sleeved outside the pulley. In this embodiment, the second motor 5 also drives the second transmission mechanism 6 to operate via a belt drive structure, which will not be elaborated here.

[0044] The carrier 4 is rotatably provided with a second shaft body 24. The second shaft body 24 is provided with a second eccentric wheel 25. The second transmission mechanism 6 includes a plurality of transmission units 26. The transmission unit 26 includes a fourth plate member 27, a fifth plate member 28 and a second support member 29. One end of the fourth plate member 27 is sleeved outside the second eccentric wheel 25. The other end of the fourth plate member 27 is rotatably provided with one end of the fifth plate member 28. The lower end of the second support member 29 is fixedly provided on the carrier 4. The middle part of the fifth plate member 28 is rotatably provided with the upper end of the second support member 29. The other end of the fifth plate member 28 is rotatably provided with the support frame 7. The second motor 5 drives the second shaft body 24 to drive the second eccentric wheel 25 to rotate. The rotating second eccentric wheel 25 drives the support frame 7 to move up and down and vibrate via a plurality of transmission units 26.

[0045] Via the arrangement of a plurality of transmission units 26, it is ensured that the support frame 7 is stably arranged, avoiding the support frame 7 from tilting and turning over due to unstable force. Via the arrangement of the fourth plate member 27 and the fifth plate member 28, the vertical movement stroke of the support frame 7 is gradually decomposed, avoiding the support frame 7 from rising and falling too fast, resulting in excessive vibration, that is, avoiding the support frame 7 from moving a large stroke at one time, so that the support frame 7 moves in small-distance strokes in sequence, as described below. When the support member 7 rises from height A to height B, the distance between height A and height B is divided into continuous gradual movements; ensuring that the support frame 7 moves up and down and vibrates smoothly, improving the user experience.

[0046] The transmission unit 26 further includes a sixth plate member 31, a seventh plate member 32, and a third support member 33. The other end of the fifth plate member 28 is rotatably arranged with one end of the sixth plate member 31. The other end of the sixth plate member 31 is rotatably arranged with one end of the seventh plate member 32. One end of the third support member 33 is fixedly arranged on the carrier 4. The other end of the third support member 33 is rotatably arranged with the middle part of the seventh plate member 32. The other end of the seventh plate member 32 is rotatably arranged with the support frame 7. By using the sixth plate member 31 and the seventh plate member 32, the stroke of the up-and-down movement of the support frame 7 is further decomposed, ensuring that the support frame 7 moves step by step within the range of the up-and-down movement stroke, and ensuring the smoothness of the up-and-down vibration of the support frame 7.

[0047] The number of the transmission units 26 is two. The two transmission units 26 are arranged collinearly. The two transmission units 26 share a fourth plate member 27. The fifth plate members 28 of the two transmission units 26 away from each other are respectively rotatably arranged at different positions of the carrier 4. Through the arrangement of the two transmission units 26, the forces on the support frames 7 on both sides of the second shaft body 24 are roughly balanced, avoiding poor use due to uneven force on the support frames 7.

[0048] The number of the transmission units 26 is four, and the number of the second eccentric wheels 25 is two. The two second eccentric wheels 25 are respectively located at the left and right ends of the second shaft body 24. Any end of the second shaft body 24 corresponds to two transmission units 26. The two transmission units 26 at the same end of the second shaft body 24 are arranged collinearly. When the second motor 5 drives the second shaft body 24 to rotate, it avoids uneven forces at both ends of the second shaft body 24 resulting in uneven vibration at both ends of the second shaft body 24, and ensures the smoothness of the vibration of the support frame 7.

[0049] The second shaft body 24 and the second eccentric wheel 25 are of an integral structure. The central axis of the second shaft body 24 and the central axis of the second eccentric wheel 25 are spaced apart from each other and arranged in parallel. A second bearing 34 is sleeved outside the second eccentric wheel 25. One end of the fourth plate member 27 is rotatably sleeved outside the second bearing 34. By means of the arrangement of the second bearing 34, the frictional noise between the second eccentric wheel 25 and the fourth plate member 27 is reduced, the wear between the two is delayed, and the service life of the two is prolonged.

[0050] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
