Description

Shock attenuation bed body

Technical Field

The utility model belongs to the field of health care beds, in particular to a damping bed body.

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 for horizontal and vertical swinging have been proposed in the prior art, and the above-described mechanism is then used in healthcare equipment. 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 increasing the speed of horizontal oscillation or continuously increasing the speed of vertical oscillation, and naturally, when a mechanism moves horizontally at a high speed, it is difficult to superpose a vertical motion at a high speed.

The applicant previously filed "CN 2020205191646 a curved reciprocating swing mechanism and a device thereof", which moves a movable support both up and down and back and forth during use. Because the bed body swings at high speed and the center of gravity is not at the center, if the bed body is not fixed well, the whole bed body can continuously move towards one direction.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a shock attenuation bed body avoids the bed body to last to move towards certain direction at the swing in-process.

In order to realize the above-mentioned purpose, the utility model provides a shock attenuation bed body, including the upper bed body, the lower bed body, drive mechanism and motor, the lower bed body is fixed, drive mechanism with the motor all install in the lower bed body, the motor passes through the drive mechanism drive the upper bed body realizes the arc swing, will horizontal motion's direction is called the fore-and-aft direction when the upper bed body arc swings, will the direction of vertical motion is called upper and lower direction when the upper bed body arc swings, the bottom of the lower bed body is equipped with a plurality of foot pads, the callus on the sole is including being used for connecting the upper bracket of the lower bed body, the lower carriage and a plurality of setting as load-bearing platform are in the upper bracket with shock attenuation unit between the lower carriage, the callus on the sole respectively arranges a shock attenuation unit in the front and back direction at least.

As a modification of the above, the shock absorbing unit includes a damper and a spring.

As an improvement of the proposal, the lower bed body is evenly provided with four foot pads at the peripheral edge.

As a modification of the above, the foot pad has two of the shock absorbing units, and the two shock absorbing units are respectively arranged in the front and rear directions.

As an improvement of the scheme, the distance between the two shock absorption units of the same foot pad is 3-6 cm.

As an improvement of the scheme, the upper bracket and the lower bracket are both oblong sheet bodies.

The utility model discloses following beneficial effect has: the arc motion of the upper bed body can be decomposed into a horizontal vector and a vertical vector, and the two vectors are reflected as the oblique impact in the front-back direction most of the time after being combined. At the moment, the foot pad is mainly stressed in a reciprocating manner in the front-back direction, the arrangement of the damping units is reasonably and respectively positioned in the front-back direction, the damping units can also swing in an arc manner in the front-back up-down direction properly, the swing of the lower bed body is just counteracted, and the front-back deviation of the lower bed body is effectively avoided (the lower bed body does not generate impact force in other directions, so the damping units can not be arranged in other directions).

Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Referring to fig. 1 to 4, the utility model discloses a damping bed body optimizes prior device, has solved the hidden danger that prior device exists. The bed body comprises an upper bed body 12, a lower bed body 11, a transmission mechanism 13 and a motor 14, wherein the lower bed body 11 is fixed, the transmission mechanism 13 and the motor 14 are both arranged on the lower bed body 11, and the motor 14 drives the upper bed body 12 to realize arc-shaped swing through the transmission mechanism 13. The specific structure and principle of the bed body can refer to "CN 2020205191646 an arc reciprocating swing mechanism and device thereof", which is not described herein again.

The direction of the horizontal movement when the upper bed body 12 swings in an arc shape is referred to as the front-back direction (i.e., the left-right direction in fig. 1, the direction perpendicular to the paper in fig. 2, and the left-right direction in fig. 4), the direction of the vertical movement when the upper bed body 12 swings in an arc shape is referred to as the up-down direction, the arc-shaped movement of the upper bed body 12 can be decomposed into a horizontal vector and a vertical vector, and most of the time after the two vectors are combined is reflected as the oblique impact in the front-back direction. The bottom of the lower bed body 11 is provided with a plurality of foot pads 20, each foot pad 20 comprises an upper bracket 23 used for connecting the lower bed body 11, a lower bracket 24 used as a bearing platform, and a plurality of shock absorption units arranged between the upper bracket 23 and the lower bracket 24, and each foot pad 20 is at least provided with one shock absorption unit in the front-back direction. The damping units are reasonably arranged in the front and back directions respectively, and can also swing in an arc shape in the front and back and up and down directions properly, so that the swing of the lower bed body 11 is just offset, and the front and back deviation of the lower bed body 11 is effectively avoided. As shown in fig. 2, the foot pad 20 is not subjected to an impact force in the left-right direction, and a shock absorbing unit is not generally provided, but may be additionally provided as the case may be, for the purpose of balancing the upper and lower brackets 24 of the foot pad 20.

The shock absorption unit has the effect of absorbing the impact of the lower bed body 11. In this embodiment, the shock absorbing unit includes a damper 21 and a spring 22, which in combination can effectively slow down the speed and the sub-impact. In other embodiments, the damping unit is entirely a spring 22 or an air cushion. In this embodiment, the foot pad 20 has two of the shock absorbing units, and the two shock absorbing units are respectively arranged in the front and rear directions. Further, the distance between the two shock absorption units of the same foot pad 20 is 3-6 cm. The spring 22 of the front and rear shock absorbing units can be seen in fig. 1, and the damper 21 is hidden at the back of the spring 22; the spring 22 and damper 21 of one damping unit can be seen in fig. 2, the latter damping unit being hidden.
