Description

Rhythm device and rhythm bed

The creation system is related to the rhythm device and the rhythm bed; in particular, a rhythm device that can make the carrier member reciprocate and rhythm and a rhythm bed using the rhythm device.

Modern people are busy with life, and the relative exercise time is reduced. The long-term lack of exercise is likely to cause chronic diseases, which leads to a decline in the national health rate. On the other hand, the social population has become increasingly aging in recent years, and the elderly are often unable to exercise because of joint aging. Therefore, there are beds on the market that can perform vertical vibration or parallel rhythm, so that people who do not exercise often or cannot exercise can also exercise during rest.

The parallel rhythm bed is equipped with a rhythm device under the mattress to make the mattress parallel to the rhythm. In the prior art, the rhythm device uses a motor to drive a plurality of wheel bodies to rotate, and then the belt is driven by a belt around the wheel body. Or the frame under the mattress is swinged back and forth in parallel. However, this method requires the motor to drive the wheel body to rotate in different directions to achieve the reciprocating effect. In other words, when the motor drives the wheel body to rotate clockwise, the belt is driven by the wheel body to advance and the frame and the mattress face toward the bed. The direction moves, and when the motor-driven wheel body rotates counterclockwise, the belt is driven by the wheel body to retreat and move the frame and the mattress toward the tail of the bed, thereby achieving a reciprocating effect.

In addition, in another rhythm device, the motor can drive one of the wheel bodies to rotate, and the screw or gear rotating together with the wheel body can drive the frame to be reciprocated in parallel with the frame of the screw or the gear. However, whether the belt or the wheel body drives the mattress to reciprocate in parallel, the motor is required to drive the wheel body to rotate in different directions. In addition to the motor must switch the driving direction, the wheel body must first overcome the inertial rotation in the previous direction to continue to rotate in the opposite direction. Therefore, when switching the reciprocating direction, it is easy to cause the rotation to be unsmooth and the reciprocating motion is not smooth, or even because The above-mentioned unsmooth operation causes equipment damage and increases maintenance costs.

On the other hand, in the prior art, there is also a rhythm device in which the frame is parallel reciprocated in such a manner that the link cooperates with the wheel. In the rhythm device, the motor controls a rotating wheel to perform continuous rotation in one direction, and the other end of the connecting rod is connected to the other end of the frame and is pivotally disposed on the rotating wheel at a position offset from the center of the wheel. Therefore, the rotating wheel continues in one direction. Rotating can be used to push and pull the connecting rod, so that the frame can reciprocate in parallel. However, in such a manner that the connecting rod achieves a reciprocating motion, the kinetic energy consumed by the connecting rod is excessive, so that the rhythmic device consumes a large amount of electricity and is not environmentally friendly.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the drawings. 1 and FIG. 2, FIG. 1 is a schematic diagram of a rhythm bed 1 according to an embodiment of the present invention, and FIG. 2 is a schematic cross-sectional view of the rhythm bed 1 of FIG. As shown in FIGS. 1 and 2, the rhythm bed 1 includes a fixed base 10, a rhythmic base 12, and a rhythm device 14 disposed therebetween. In this embodiment, the rhythm bed 1 can be used as a bed for medical or health care, for the user to lie on it to perform parallel rhythm to the user, but the practice is not limited thereto, and any parallel rhythm The functional carrier is the scope of this creation. In addition, in practical applications, the rhythm bed 1 can also have a vertical vibration function.

Please refer to FIG. 3 and FIG. 4. FIG. 3 is a partial schematic view of the rhythm bed 1 of FIG. 2, and FIG. 4 is a partial schematic view of the rhythm bed 1 of FIG. As shown in FIG. 3 and the figure, the rhythm device 14 has a motor 140, an eccentric wheel 141, a first pulley 142, a first belt 143, and a return mechanism 144. The eccentric wheel 141 is disposed on the fixed base 10, and the first pulley 142 is disposed on the rhythm base 12, and the first belt 143 surrounds the eccentric wheel 141 and the first pulley 142 to interlock the two. The eccentric 141 is connectable to the motor 140 and is drivable by the eccentric shaft 1410 as a rotational axis. Since the eccentric shaft 1410 of the eccentric wheel 141 is not the axis, when the eccentric wheel 141 rotates with the eccentric shaft 1410 as the rotating shaft, the wheel surface of the eccentric wheel 141 far from the eccentric shaft 1410 will abut against the first belt 143 to pull the first The pulley 142 is exemplified by the arrangement of FIG. 3. When the eccentric wheel 141 is rotated until the wheel surface farther from the eccentric shaft 1410 is located on the right side of the eccentric shaft 1410, the first pulley is pulled to the right and the rhythm base is pulled together. 12 moves to the right. Please note that in the specific embodiment, the position of the first pulley 142 is farther from the center of the eccentric bed 141 than the eccentric wheel 141, but it is not limited thereto. In practice, the first pulley can also be disposed away from the center. The center of the rhythm bed is closer to the center.

In the present embodiment, the return mechanism 144 further includes a second pulley 145 and a second belt 146. The second pulley 145 is disposed on the rhythmic base 12 and disposed opposite to the first pulley 142. The second belt 146 surrounds the second pulley 145 and the eccentric wheel 141 such that the eccentric wheel 141 and the second pulley 145 are movable through the second belt 146. Since the second pulley 145 is disposed opposite the first pulley 142, the second pulley 145 can provide a restoring force opposite to the direction in which the first pulley 142 pulls the rhythmic base 12. Please note that the second belt 146 and the first belt 143 respectively surround different portions of the eccentric wheel 141, and the two do not interfere with each other.

As described above, when the eccentric wheel 141 is rotated by the motor, the first pulley 142 can be linked to move the rhythm base 12 in one direction, and the second pulley 145 can be moved in the opposite direction to form a parallel rhythm effect.

The manner in which the rhythm device 14 drives the rhythm base 12 to perform parallel rhythm will be described in detail below. Please refer to FIG. 5 and FIG. 6 . FIG. 5 and FIG. 6 are schematic diagrams of the rhythm device 14 of FIG. 3 interlocking with the rhythm base 12 . As shown in FIG. 5, when the eccentric wheel 141 driven by the motor 140 rotates clockwise, and the wheel surface away from the eccentric shaft 1410 is rotated to the right side of the eccentric shaft 1410, the wheel surface will abut against the first belt 143, so that the first pulley 142 is pulled and moved to the right. Since the first pulley 142 is disposed on the rhythm base 12, the rhythmic base 12 is also pulled together when the first pulley 142 is pulled, and the rhythmic base 12 is moved to the right with respect to the fixed base 10. In contrast, the eccentric wheel 141 does not abut against the second belt 146 at this time, so the second pulley 145 does not exert a pulling effect on the rhythmic base 12. On the other hand, as shown in FIG. 6, when the eccentric 141 continues to rotate in the clockwise direction, and the wheel surface away from the eccentric shaft 1410 is turned to the left side of the eccentric shaft 1410, its tread will abut against the second belt 146 and pull The second pulley 145 moves to the left. Similarly, since the second pulley 142 is disposed on the rhythm base 12, the rhythmic base 12 is also pulled together when the second pulley 145 is pulled, and the rhythmic base 12 is moved to the left with respect to the fixed base 10. In contrast, the eccentric wheel 141 does not abut against the first belt 143 at this time, so the first pulley 142 does not exert a pulling effect on the rhythmic base 12.

As described above, the motor 140 drives the eccentric wheel 141 to continuously rotate in the clockwise direction, that is, the rhythmic base 12 of the rhythm bed 1 can be driven to perform parallel reciprocating rhythm with respect to the fixed base 10. In addition, the motor 140 can also drive the eccentric 141 to continuously rotate in the counterclockwise direction, and the above-described parallel reciprocating rhythm effect can also be achieved. Since the motor 140 only needs to drive the eccentric wheel 141 to continuously rotate in a single direction, and does not need to switch the rotation direction, the problem of the prior art can be avoided to make the reciprocating motion smooth, further preventing damage to the device, and even allowing the use of lying on the rhythm bed. More comfortable. In addition, through the eccentric wheel and the belt pulling the pulley, the kinetic energy provided by the motor can be prevented from being excessively consumed in the parallel direction, and the rhythm of the creation is compared with the rhythm device which generates the parallel reciprocating motion of the connecting rod in the prior art. The device is more energy efficient.

Referring to FIG. 3 and FIG. 4 again, in the specific embodiment, the rhythm device 14 may further include a drive pulley set 147 for connecting the motor 140 and the eccentric wheel 141. As shown in FIGS. 3 and 4, the drive pulley set 147 includes a first drive wheel 1470, a first drive belt 1472, a second drive wheel 1474, and a second drive belt 1476, wherein the first drive wheel 1470 and the second drive wheel 1474 They are all disposed on the fixed base 10. The first transmission wheel 1470 can be coupled to the motor 140 through the first transmission belt 1472, and the axis of the second transmission wheel 1474 is coupled to the eccentric shaft 1410 of the eccentric wheel 141 such that the eccentric wheel 141 can rotate together with the second transmission wheel 1474. Also, the second drive belt 1476 can surround the first drive wheel 1470 and the second drive wheel 1474 to interlock the two. Please note that the first transmission belt 1472 and the second transmission belt 1476 are wrapped around different portions of the first transmission wheel 1470 without mutual interference.

When the motor 140 starts to rotate, the first transmission belt 1472 is driven, and the first transmission belt 1472 drives the first transmission wheel 1470 to rotate. Then, the rotation of the first transmission wheel 1470 is transmitted to the second transmission wheel 1474 through the second transmission belt 1476 to drive the second transmission wheel 1474 to rotate, so that the eccentric wheel 141 coupled with the second transmission wheel 1474 can be driven to rotate.

By the drive pulley set 147, the motor 140 can be disposed at other portions of the rhythm bed 1 without directly connecting the eccentric wheel 141, so that the configuration of the components of the rhythm device 14 can be more free. In addition, the first transmission wheel 1470 can also generate a deceleration and buffering function, so that the rhythm bed 1 can move more smoothly when parallel reciprocating rhythm is performed.

In the present embodiment, the rhythm device 14 uses the eccentric wheel 141 and two opposing pulleys connected to the rhythm base 12 to drive the rhythm base 12 such that it can produce parallel reciprocating rhythm with respect to the fixed base 10. However, in practice, the rhythm device of this creation can also present different implementations. Please refer to FIG. 7 and FIG. 8. FIG. 7 is a partial schematic view of the rhythm bed 2 according to another embodiment of the present invention. FIG. 8 is a partial schematic view of the rhythm bed 3 according to still another embodiment of the present invention.

As shown in FIG. 7 , the specific embodiment is different from the previous embodiment in that the recovery mechanism 244 of the specific embodiment includes a tension spring, and the two ends of the tension spring are connected to the fixed base 20 of the rhythm bed 2 and Rhythm base 22. It should be noted that the other components of the specific embodiment are substantially the same as the components corresponding to the previous embodiment, and thus will not be further described herein. When the motor 240 drives the eccentric 241 to rotate to the right side of the eccentric shaft 2410, the rhythm base 22 is pulled to move to the right side, and at this time, the tension spring is pulled by the rhythm base 22 to elongate. Therefore, the tension spring provides the leftward elastic restoring force to the rhythmic base 22. When the motor 240 continues to drive the eccentric 241 to rotate to the left side of the eccentric shaft 2410 on the left side of the eccentric shaft 2410, the eccentric wheel 241 pulls the force of the first pulley 242 and the rhythm base 22 to disappear, and the tension spring pair The elastic restoring force provided by the rhythm base 22 will pull the rhythm base 22 to the left. Then, when the motor 240 continues to drive the eccentric wheel 241 to rotate, and the wheel surface of the eccentric wheel 241 away from the eccentric shaft 2410 is again located to the left of the eccentric shaft 2410, the rhythm base 22 will be pulled again to move to the left. Thereby, the rhythm bed 2 can generate parallel reciprocating rhythm.

As shown in FIG. 8, the recovery mechanism 344 of the present embodiment includes a compression spring, and the two ends of the compression spring are connected to the fixed base 30 and the rhythm base 32 of the rhythm bed 3. It should be noted that other components of the specific embodiment are substantially the same as those of the foregoing specific embodiments, and thus will not be described again. Similarly, the motor 340 can drive the eccentric wheel 341 to pull the rhythm base 32 to move, and the compression spring provides the elastic restoring force in the opposite direction to the rhythm base 32, and when the eccentric wheel 341 rotates to not provide the force to the rhythm base 32, The elastic restoring force will pull the rhythmic base 32 to move in the opposite direction to produce parallel reciprocating rhythm. The difference between this embodiment and the previous embodiment is only the difference in the type of the spring and the connection relationship between the spring and the fixed base and the rhythm base. In practice, the recovery mechanism includes an elastic response that provides the opposite direction. The elastic body of the force can be. Moreover, the returning mechanism only needs to provide the restoring force in the opposite direction. For example, the specific embodiment of Fig. 3 provides the restoring force in the opposite direction with the second pulley 145 and the second belt 146.

It can be seen from the various embodiments described above that the rhythm device of the present invention has an eccentric wheel, a pulley connected to the eccentric through the belt, and a return mechanism, and the motor can drive the eccentric to rotate in a single direction to reach the pulling rhythm bed or the carrier. The effect of parallel reciprocating rhythm. Thereby, the rhythmic moving bed or the carrier can be smoothly parallel reciprocating rhythm, so that the probability of equipment damage is reduced, and even the user lying on the rhythm bed can be more comfortable. In addition, the rhythm device of the present invention can achieve more power saving and environmental protection effects than the prior art that generates parallel reciprocating motion through the connecting rod.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
