Description

Rhythm device and rhythm bed

The invention relates to a rhythmic device and a rhythmic bed; in particular, it relates to a rhythmic device capable of reciprocating rhythmic movement of a carrier and a rhythmic bed using the rhythmic device.

Modern people have a busy life and relatively reduced exercise time, while chronic lack of exercise can easily lead to chronic diseases and lead to a decline in the national health rate. On the other hand, the social population is getting older in recent years, and the elderly are often unable to exercise because of aging joints. Therefore, there are beds on the market that can perform vertical vibrations or parallel rhythms, so that people who do not usually exercise or cannot exercise can also exercise at rest.

The parallel rhythmic bed is provided with a rhythmic device under the mattress so that the mattress can be moved in parallel. In the prior art, the rhythmic device uses a motor to drive a plurality of wheel bodies to rotate, and then the mattress is driven by a belt around the wheel body. Or the frame under the mattress swings back and forth in parallel. However, this method requires the motor-driven wheel body to rotate in different directions to achieve the back-and-forth movement effect. In other words, when the motor-driven wheel body rotates clockwise, the belt is driven by the wheel body to move forward and the frame and mattress toward the bed head. When the motor drives the wheel body to rotate counterclockwise, the belt is driven back by the wheel body and moves the frame and the mattress toward the end of the bed, thereby achieving the effect of reciprocating motion.

In addition, in another rhythmic device, a motor can drive one of the wheel bodies to rotate, and a screw or gear rotating with the wheel body can drive a frame linked with the screw or gear to perform parallel reciprocating movements. However, whether the mattress is driven to reciprocate in parallel by a belt or a wheel, a motor is required to drive the wheel to rotate in different directions. In addition to the motor must switch the driving direction, the wheel must also 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 produce a situation where the rotation is not smooth and the reciprocating motion is not smooth. The above-mentioned unsmooth actions cause equipment damage and increase maintenance costs.

On the other hand, there is another kind of rhythmic device in the prior art that makes the frame perform parallel reciprocating movements in the manner of connecting rods and wheels. In this rhythmic device, the motor controls a runner to make continuous rotation in one direction, and the other end of the connecting rod is pivotally located at a position off the center of the runner, so the runner continues in a single direction. The rotation can perform the function of pushing and pulling the connecting rod, so that the frame performs parallel reciprocating motion. However, this way of using the connecting rod to achieve reciprocating motion consumes too much kinetic energy on the connecting rod, resulting in large power consumption of such a rhythmic device and not environmental protection.

Therefore, it is necessary to develop a new type of rhythmic device and rhythmic bed to solve the above problems.

In view of this, an object of the present invention is to provide a rhythmic device that can be used in a carrier and smoothly reciprocates the carrier in parallel.

In order to achieve the above object, the rhythm device provided by the present invention includes a motor, an eccentric wheel, a first pulley, a first belt, and a return mechanism, wherein the motor and the eccentric wheel are disposed on a fixed base of the carrier, and the first pulley and the return The mechanism is arranged on the rhythmic base of the carrier. The eccentric wheel is connected to a motor, which can be driven by the motor to rotate with its eccentric shaft as a rotating shaft. The first belt surrounds the eccentric wheel and the first pulley. When the eccentric wheel is driven by the motor to rotate, the eccentric wheel can be linked with the first pulley through the first belt to cause the first pulley to pull the rhythmic base. The restoring mechanism can provide a restoring force to the rhythmic base opposite to the direction in which the first pulley pulls the rhythmic base. With this, the rhythm device can make the carrier perform parallel reciprocating rhythm.

Another object of the present invention is to provide a rhythmic bed capable of reciprocating in parallel.

In order to achieve the above object, the rhythmic bed provided by the present invention includes a fixed base, a rhythmic base, and a rhythmic device. The rhythmic device further includes a motor, an eccentric wheel, a first pulley, a first belt, and a return mechanism. The motor and the eccentric are arranged on a fixed base, and the first pulley and the return mechanism are arranged on a rhythmic base. The eccentric wheel is connected to a motor, which can be driven by the motor to rotate around its eccentric shaft. The first belt surrounds the eccentric wheel and the first pulley. When the eccentric wheel is driven by the motor to rotate, the eccentric wheel can be linked with the first pulley through the first belt to cause the first pulley to pull the rhythmic base. The restoring mechanism can provide a restoring force to the rhythmic base opposite to the direction in which the first pulley pulls the rhythmic base. With this, the rhythm bed can perform parallel reciprocating rhythm.

Therefore, the present invention can achieve the effect of making the rhythmic bed or the carrier smoothly perform parallel reciprocating rhythms.

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

Please refer to FIGS. 3 and 4. FIG. 3 is a partial schematic diagram of the rhythmic bed 1 of FIG. 2, and FIG. 4 is a partial schematic diagram of the rhythmic bed 1 of FIG. 2 from another perspective. As shown in FIG. 3 and FIG. 3, the rhythm device 14 includes 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 belt pulley 142 is disposed on the rhythmic base 12. The first belt 143 surrounds the eccentric wheel 141 and the first belt pulley 142 to link the two. The eccentric wheel 141 can be connected to the motor 140 and can be driven to rotate by using the eccentric shaft 1410 as a rotation axis. Since the eccentric shaft 1410 of the eccentric wheel 141 is not a shaft center, when the eccentric wheel 141 rotates with the eccentric shaft 1410 as a rotation axis, 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, taking the configuration of FIG. 3 as an example, when the eccentric 141 rotates until the above-mentioned wheel surface farther from the eccentric shaft 1410 is located on the right side of the eccentric shaft 1410, it will pull the first pulley to the right and pull the rhythm base together. 12Move right. Please note that in this specific embodiment, the position of the first pulley 142 is farther from the center of the moving bed 1 than the eccentric wheel 141, but it is not limited to this. In practice, the first pulley may also be disposed at a distance from The center of the rhythmic bed is closer.

In this 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 is opposite to the first pulley 142. The second belt 146 surrounds the second pulley 145 and the eccentric wheel 141, so that the eccentric wheel 141 and the second pulley 145 can be linked through the second belt 146. Since the second pulley 145 and the first pulley 142 are oppositely disposed, 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 parts of the eccentric wheel 141, and they do not interfere with each other.

As described above, when the eccentric wheel 141 rotates under the control of the motor, the first pulley 142 can be linked to move the rhythmic base 12 to one direction, and the second pulley 145 can be linked to move in the opposite direction to form a parallel rhythmic effect.

The following describes in detail the manner in which the rhythm device 14 drives the rhythm base 12 to perform parallel rhythms. Please refer to FIG. 5 and FIG. 6, which are schematic diagrams of the linkage between the rhythm device 14 and the rhythm base 12 of FIG. 3. As shown in FIG. 5, when the eccentric wheel 141 driven by the motor 140 and rotated clockwise is rotated away from the wheel surface of the eccentric shaft 1410 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 to move to the right. Since the first pulley 142 is disposed on the rhythmic base 12, the rhythmic base 12 is also pulled together when the first pulley 142 is pulled, so that the rhythmic base 12 moves to the right relative 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 belt wheel 145 has no pulling effect on the rhythmic base 12. On the other hand, as shown in FIG. 6, when the eccentric wheel 141 continues to rotate in a clockwise direction, and the wheel surface away from the eccentric shaft 1410 is turned to the left of the eccentric shaft 1410, its wheel surface will abut against the second belt 146 and pull The second pulley 145 moves to the left. Similarly, since the second pulley 142 is provided on the rhythmic base 12, the rhythmic base 12 is also pulled together when the second pulley 145 is pulled, so that the rhythmic base 12 moves to the left relative 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 has no pulling effect on the rhythmic base 12.

As described above, the motor 140 drives the eccentric wheel 141 to continuously rotate in a clockwise direction, thereby driving the rhythmic base 12 of the rhythmic bed 1 to perform parallel reciprocating rhythms relative 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 parallel reciprocating rhythm effect described above 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 direction of rotation, it can avoid the problems of the prior art and make the reciprocating movement smooth, further prevent the equipment from being damaged, and even use it when lying on a rhythmic bed. People are more comfortable. In addition, the way of pulling the pulley through the eccentric wheel and the belt can prevent the kinetic energy provided by the motor from being excessively consumed outside the parallel direction. Compared with the prior art device that generates parallel reciprocating motion by the connecting rod, the rhythm of the present invention The device is more power efficient.

Please refer to FIG. 3 and FIG. 4 again. In this embodiment, the rhythm device 14 may further include a transmission pulley set 147 for connecting the motor 140 and the eccentric wheel 141. As shown in FIG. 3 and FIG. 4, the transmission pulley group 147 includes a first transmission wheel 1470, a first transmission belt 1472, a second transmission wheel 1474, and a second transmission belt 1476, wherein the first transmission wheel 1470 and the second transmission wheel 1474 Both are disposed on the fixed base 10. The first transmission wheel 1470 can be connected to the motor 140 through the first transmission belt 1472, and the axis of the second transmission wheel 1474 is connected to the eccentric shaft 1410 of the eccentric wheel 141, so that the eccentric wheel 141 can rotate with the second transmission wheel 1474. In addition, the second transmission belt 1476 may surround the first transmission wheel 1470 and the second transmission wheel 1474 so as to interlock the two. Please note that the first transmission belt 1472 and the second transmission belt 1476 surround different parts of the first transmission wheel 1470, and the two do not interfere with each other.

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. Therefore, the eccentric wheel 141 linked with the second transmission wheel 1474 can be driven to rotate.

By transmitting the belt pulley set 147, the motor 140 can be installed in other parts of the rhythmic bed 1 without directly connecting the eccentric wheel 141, so that the configuration of the components of the rhythmic device 14 can be more freely. In addition, the first transmission wheel 1470 can also produce deceleration and buffer functions, so that the rhythmic bed 1 can move more smoothly when performing parallel reciprocating rhythmic movements.

In this embodiment, the rhythmic device 14 drives the rhythmic base 12 by using an eccentric wheel 141 and two opposite pulleys connected to the rhythmic base 12, so that it can generate a parallel reciprocating rhythmic motion relative to the fixed base 10. However, in practice, the rhythm device of the present invention can also show different implementation modes. Please refer to FIG. 7 and FIG. 8. FIG. 7 is a partial schematic diagram of the rhythmic bed 2 according to another embodiment of the present invention, and FIG. 8 is a partial schematic diagram of the rhythmic bed 3 according to another embodiment of the present invention.

As shown in FIG. 7, this embodiment is different from the previous embodiment in that the recovery mechanism 244 of this embodiment includes a tension spring, and both ends of the tension spring are connected to the fixed base 20 and the fixed bed 20 of the moving bed 2 and Rhythm base 22. Please note that the other components of this specific embodiment are substantially the same as the corresponding components of the previous specific embodiment, so they are not repeated here. When the motor 240 drives the eccentric wheel 241 to rotate so that the wheel surface away from the eccentric shaft 2410 is on the right side of the eccentric shaft 2410, the rhythmic base 22 is pulled to move to the right side, and at this time, the tension spring is pulled by the rhythmic base 22 to extend, The tension spring thus provides a leftward elastic restoring force to the rhythmic base 22. When the motor 240 continues to drive the eccentric wheel 241 to rotate until the wheel surface away from the eccentric shaft 2410 is on the left side of the eccentric shaft 2410, the force of the eccentric wheel 241 pulling the first pulley 242 and the rhythmic base 22 disappears. The elastic restoring force provided by the rhythmic base 22 will pull the rhythmic base 22 to the left. Next, when the motor 240 continues to drive the eccentric wheel 241 to rotate, so that the wheel surface of the eccentric wheel 241 away from the eccentric shaft 2410 is located on the left side of the eccentric shaft 2410 again, the rhythm base 22 will be pulled again to move to the left. Thereby, the rhythmic bed 2 can generate a parallel reciprocating rhythm.

As shown in FIG. 8, the recovery mechanism 344 of this embodiment includes a compression spring, and both ends of the compression spring are connected to the fixed base 30 and the rhythmic base 32 of the rhythmic bed 3. Please note that the other components of this specific embodiment are substantially the same as the corresponding components of the foregoing specific embodiment, so they will not be repeated here. Similarly, the motor 340 can drive the eccentric wheel 341 to pull the rhythmic base 32 to move, and the compression spring provides the elastic restoring force in the opposite direction to the rhythmic base 32, and when the eccentric wheel 341 rotates to provide no force to the rhythmic base 32, The elastic restoring force will pull the rhythmic base 32 to move in the opposite direction to generate a parallel reciprocating rhythm. The difference between this specific embodiment and the previous embodiment is only the difference in the type of spring and the connection relationship between the spring and the fixed base and the rhythmic base. In practice, the recovery mechanism includes an elastic recovery that can provide the opposite direction. Forced elastomer is sufficient. Furthermore, the returning mechanism only needs to provide a returning force in the opposite direction. For example, the specific embodiment of FIG. 3 uses the second pulley 145 and the second belt 146 to provide the returning force in opposite directions.

It can be known from the above specific embodiments that the rhythm device of the present invention has an eccentric wheel, a pulley connected to the eccentric wheel through a belt, and a return mechanism. The motor can drive the eccentric wheel to rotate in a single direction to reach the moving bed or the carrier. The effect of parallel reciprocating rhythm. With this, the rhythmic bed or carrier can smoothly perform parallel reciprocating rhythms, reduce the probability of equipment damage, and even make the user lying on the rhythmic bed more comfortable. In addition, compared with the prior art of generating parallel reciprocating motion through the connecting rod, the rhythm device of the present invention can achieve more power-saving and environmental protection effects.
