Description

Arc reciprocating swing mechanism and device thereof

Technical Field

The invention belongs to the field of health-care equipment, and particularly relates to an arc-shaped reciprocating swinging mechanism and a device thereof.

Background

Research shows that (referring to the influence and mechanism progress of whole-body horizontal vibration training on the cardiovascular system, Chinese rehabilitation theory and practice, vol. 25, 4 th of 2019 in 4 months), whole-body vibration training can achieve the purposes of relaxing blood vessels, improving blood circulation, improving pulse pressure and the like, and is beneficial to the physical and mental health of users. The specific principle is as follows: whole body vibration-clapping phenomenon-increasing blood flow rate-increasing shearing force, stimulating endothelial cells-increasing NO content-acting as gas signal molecules-relaxing blood vessels.

Many solutions have been proposed in the prior art for horizontal and vertical vibrations, and the above-described mechanism is then used in healthcare facilities. The reason that the prior art does not combine horizontal and vertical motions is that the prior art has gone into an isolated direction of development, continuously increases the speed of horizontal vibration or continuously increases the speed of vertical vibration, and naturally, when a mechanism moves horizontally at a high speed, it is difficult to superpose a vertical motion at a high speed.

Disclosure of Invention

The invention aims to provide an arc-shaped reciprocating swing mechanism and a device thereof, which organically combine the motions on a vertical surface, thereby overcoming the defect that the prior art can only move horizontally or vertically independently.

In order to achieve the above object, the present invention provides an arc-shaped reciprocating swing mechanism, comprising: a base support; the movable bracket is arranged above the basic bracket; the arc-shaped swinging pieces are uniformly arranged between the base support and the movable support, each arc-shaped swinging piece comprises an upper connecting plate, a lower connecting plate and connecting rods, the upper ends and the lower ends of the connecting rods are respectively hinged with the upper connecting plate and the lower connecting plate, the connecting rods are parallel to each other, the upper connecting plate is fixedly connected with the movable support, and the lower connecting plate is connected with the base support; and the output end of the driving mechanism is connected with the movable support, and the driving mechanism pushes the movable support to swing back and forth under the limitation of each arc-shaped swinging piece.

By adopting the scheme, the arc-shaped swinging piece can only swing in a reciprocating mode, and the hinged position of the lowest point is fixed according to the position in fig. 2, the highest point swings leftwards and downwards, and the highest point swings rightwards and moves rightwards and downwards. Since the movable bracket is installed above each arc-shaped swinging member, the movable bracket naturally attaches a state of vertical movement when moving horizontally. Based on the vibration in the horizontal and vertical directions, the vibration of the whole body is really realized, and the effects of better relaxing blood vessels, improving blood circulation, improving pulse pressure, increasing joint muscle movement, increasing bone density, promoting respiration and the like are realized.

As an improvement of the scheme, each arc-shaped swinging part comprises two connecting rods and two rotating shafts, the lower connecting plate and the upper connecting plate respectively comprise a flat plate part and a shaft seat part with a through hole inside, the shaft seat part is installed on the flat plate part, the two rotating shafts are respectively inserted into the two shaft seat parts, the two rotating shafts are arranged in parallel, the two lower connecting plates are respectively positioned at the head end and the tail end of the shaft seat part, the lower sides of the two connecting rods are penetrated through by the rotating shafts of the lower connecting plate, the upper sides of the two connecting rods are penetrated through by the rotating shafts of the upper connecting plate, and the two connecting rods are arranged in parallel. The arc-shaped swinging piece needs to bear a large amount of pressure and move back and forth, and the simpler the structure and the more reliable the structure performance are.

In other solutions, there is a simple combination of a horizontal push rod and a vertical push rod, i.e. the horizontal push rod pulls the first platform to move horizontally, the vertical push rod is mounted on the first platform, and then the second platform is arranged, and the vertical push rod pulls the lifting movement. After the movement is decomposed, the movement can be diversified, but the structure complexity, the control difficulty and the cost are greatly improved.

As an improvement of the scheme, a bearing is arranged between the rotating shaft and the shaft seat part. The selectable plastic bearing, the ceramic bearing or the deep groove ball bearing can effectively reduce the noise generated by the friction of the rotating shaft. In other schemes, the outer wall of the rotating shaft is directly attached to the inner wall of the shaft seat part.

As an improvement of the scheme, the base support is a rectangular frame, the inner side of the base support is provided with a plurality of reinforcing rods, the movable support is a rectangular frame, the inner side of the movable support is provided with a plurality of reinforcing rods, and the four arc-shaped swinging pieces are uniformly arranged on two longer rods between the base support and the movable support. In other schemes, the ground can be directly used as a basic bracket, and the movable bracket can also be a flat plate. In other versions, three or six arcuate pendulums may be arranged.

As an improvement of the scheme, the driving mechanism is an eccentric transmission mechanism and comprises a motor, a rotating wheel and a transmission rod, the motor is connected with the rotating wheel to provide power, one end of the transmission rod is hinged with the movable support, and the other end of the transmission rod is hinged with the eccentric position of the rotating wheel. By adopting the scheme, the strength of the rotating wheel is enough, and the rotating wheel can balance weight to store potential energy, so that the movement of the movable support is more stable. As long as the effect of the reciprocating oscillation of the transmission rod is achieved, in other embodiments a lever may be used instead of a wheel, in which case a crank-rocker mechanism is formed. If high-speed movement is needed, the rotating speed of the motor and the strength of relevant parts are improved.

As an improvement of the scheme, the motor is connected with the rotating wheel through a speed reducer. The stress of the movable support can be transmitted to the motor, and by adopting the scheme, the speed reducer can reduce the moment born by the motor and properly protect the motor. Of course, in other schemes, the motor has good quality, the movable support needs to move at high speed, and the motor can also directly drive the rotating wheel.

As an improvement of the scheme, the motor is arranged on the base bracket. By adopting the scheme, the whole mechanism is equivalent to a relatively independent part and can be flexibly transferred to other positions. In other arrangements, the motor may also be mounted on the ground if it is determined that the entire mechanism is no longer moving, thereby reducing the strength requirements for the base support.

As an improvement of the scheme, the basic bracket is provided with a plurality of limiting bulges at one side close to the movable bracket, and the maximum height of each limiting bulge is lower than the lowest position of the movable bracket in an initial state. Generally, the height of the movable support is locked by the transmission rod, and by adopting the scheme, the movable support can be prevented from having large fall when falling accidentally, so that the safety function is realized. In other schemes, the limiting bulge can adopt a lifting structure, and when the movable support is required to be used, the limiting bulge is properly lowered to a proper height; when the movable support is not needed, the limiting bulge is lifted to support the movable support.

The device comprises a lathe bed and the arc reciprocating swing mechanism, wherein the lathe bed is arranged on the upper side of the movable support. By adopting the technical scheme, the device is mainly applied to beds, mattresses, leisure and health-care reclining chairs, sofas and the like. In other schemes, the arc-shaped reciprocating swing mechanism can also be applied to (i.e. be transformed into) the fields of original bed frames, sofas, reclining chairs, wheelchairs and the like.

As an improvement of the above scheme, the device further comprises a central processing unit, an external signal receiving module, a timing module and a storage module, wherein the central processing unit is simultaneously connected with the external signal receiving module, the timing module, the storage module and the motor; the central processing unit acquires an instruction of an external receiving module or a timing module, then transfers a common motion mode in the storage module and drives the motor to rotate at a constant speed; the central processing unit obtains the instruction of the external receiving module or the timing module, then the getting-up mode in the storage module is called, the driving motor is started, the rotating speed is slowly increased to a set working condition, and finally the driving motor is stopped.
