Preferably, the turnover mechanism 2 is arranged at the other end to be the opposite end of the opening end, and the closer to the end point of the end, the larger the storage opening after being lifted, and the simpler the storage of large articles.

Storing mechanism 3 can adopt panel to enclose to close and make, chooses for use four panels vertical to put and end-to-end connection becomes a tetragonal body, also can adopt a plurality of arcs to constitute cylinder, ellipsoid or other irregular spatial structure, and storing mechanism 3 highly depends on the height of panel, and the panel that the bottom is used for tetragonal body bottom opening to match at last seals and forms an upper portion open-ended storing mechanism 3.

Specifically, the lateral wall of storing mechanism 3 is equipped with the through-hole, be equipped with ventilation mechanism in the through-hole.

The storage mechanism 3 is generally in a closed or semi-closed state, air flow is poor, especially when the storage mechanism is in a closed state and the number of articles in the storage mechanism is large, ventilation in the storage mechanism 3 is not smooth and moist, and bacteria are easy to breed to cause mildew. In addition, the ventilation mechanism not only accelerates the air flow of the space below the bed body 1, but also is beneficial to the overall heat dissipation of the bed body 1, and is particularly beneficial to the heat dissipation of a mattress when being matched with a ventilation mattress, so that the ventilation of the back of a user is kept.

Specifically, the method further comprises the following steps: a spacer provided at the opening of the storage mechanism 3.

The opening of storing mechanism 3 is sealed through the separator, shelters from the article in the storing mechanism 3, at the bed body 1 during operation, prevents that outside article from falling into storing mechanism 3, prevents that the dust from getting into, keeps 3 inside cleanness of storing mechanism, and the people also can't see the article in storing mechanism 3, and is more pleasing to the eye. The isolating piece can be a telescopic isolating plate.

As shown in fig. 2, the turnover mechanism 2 includes: a first support 21 and a second support 22; two ends of the first supporting member 21 are respectively pivotally connected to the bed body 1 and the storage mechanism 3, two ends of the second supporting member 22 are respectively pivotally connected to the bed body 1 and the storage mechanism 3, and the first supporting member 21 and the second supporting member 22 are sequentially arranged along a direction from the rotating shaft to the opposite end of the bed body 1.

The length of the first support 21 is shorter than that of the first support 22, so that the lifting height of the bed 1 can be limited. The first supporting piece 21 and the second supporting piece 22 are in linkage fit, so that the bed body 1 can be lifted and lowered stably, and the overall supporting strength of the bed body 1 is improved.

As shown in fig. 2, the turnover mechanism 2 further includes: a third support 23 and a fourth support 24; wherein, two ends of the first supporting member 21 are respectively pivotally connected with one corresponding ends of the third supporting member 23 and the fourth supporting member 24, and two ends of the second supporting member 22 are respectively pivotally connected with the other corresponding ends of the third supporting member 23 and the fourth supporting member 24; in a closed state, the third supporting member 23 is arranged on the bottom surface of the bed body 1 in parallel, and the fourth supporting member 24 is arranged on the storage mechanism 3 and is parallel to the third supporting member 23; the included angle between the first supporting member 21 and the fourth supporting member 24 is an obtuse angle, and the included angle between the second supporting member 22 and the fourth supporting member 24 is an acute angle.

The first support member 21, the second support member 22, the third support member 23 and the fourth support member 24 are connected end to end, and the four support members are irregular quadrangles due to different lengths. When the mass of the bed body 1 is large, the turnover mechanism 2 is required to bear large weight, the stability of the lifting process is kept, and the lifting is avoided. In addition, the newly added third support member 23 and fourth support member 24 are beneficial to dispersing the weight of the bed body 1, reducing the pressure at the connection point of the first support member 21 and the second support member 22 with the storage mechanism 3, and preventing the storage mechanism 3 from being damaged by excessive pressure.

When the bed body 1 is heavy, it is relatively difficult to lift by only human power. Under the condition that the connection relationship among the first support member 21, the second support member 22, the third support member 23 and the fourth support member 24 is not changed, the third support member 23 extends towards the storage opening to form an extension portion 26, and then the first driving mechanism 25 is connected into the support structure for lifting or lowering the bed body 1, so that the user can lift or lower the bed body 1 without difficulty. In addition, the distance between the bed body 1 and the side wall of the storage mechanism 3 close to the rotating shaft is preferably controlled within 30 centimeters, so that the storage mechanism can obtain larger storage space.

The linear movement of the first driving mechanism 25 is equivalent to adding a support with variable length in the supporting structure, which can optimize the stress of the structure and provide power, and the scheme is simple to realize and avoids more complicated transmission structure. For example, the gas pole or straight-bar motor, gas pole and push rod motor all are the linear motion, and the motion goes up and down and does not need complicated drive mechanism, and direct mount can use, reduces the loss of drive power.

Further, the bed 1 includes: a base 13, a support mechanism 12 and at least two bed boards; the supporting mechanism 12 is arranged between the base 13 and the bed board; in the stretching state of the bed body 1, the projection of the support mechanism 12 on the side surface of the bed body 1 falls into the range of the cross section of the side surface of the bed body 1.

The bed board 11 is generally composed of a plurality of nonstandard bed boards, and the plurality of bed boards are sequentially pivoted with each other at junctions and horizontally arranged on the top of the base 13. The bed body 1 is in an extension state, namely the bed board is paved on the top surface of the base 13, at the moment, the supporting mechanism 12 is in a contraction state, and the bed body 1 has the smallest volume and the thinnest thickness. The plurality of bed boards can be deformed through the supporting mechanism 12, so that the bed boards can better adapt to the curve of a human body and the comfort level is increased.

When the second driving mechanism 5 works, the first connecting rod 6 is driven to rotate by taking the second connecting rod 7 as an axis, the second pulley 83 slides along the corresponding bed plate to push the bed plate to turn over, and when the bed plate turns over to 20-30 degrees relative to the base 13, the first pulley 82 also contacts with the bottom surface of the corresponding bed plate and can slide on the bottom surface of the bed plate 11. When only one pulley is used, the bed board can generate very large resistance when being turned for 20-30 degrees, and the resistance can be overcome by additionally arranging the other pulley, so that the bed board 11 can be stably turned.

When the supporting mechanism 12 is responsible for pushing the third bed plate 113, the third bed plate 113 is turned over by using the second connecting rod 7 (the lower end of fig. 3) as a rotating shaft through the pivot connection point of the supporting rod and the second connecting rod, and the horizontal direction of the turning is the same as the horizontal direction from the first pulley 82 to the second pulley 83; in addition, if the third bed plate 113 is provided with the fourth bed plate 114 in the horizontal direction from the second pulley 83 to the first slide, and one end of the fourth bed plate 114 is connected with the pivot thereof, the pivot connection end of the fourth bed plate 114 and the third bed plate 113 will also turn over relative to the base 13 along with the third bed plate 113, and at this time, only one support mechanism 12 can cause the two bed plates connected with the pivot to turn over and deform together; furthermore, still can add the third connecting rod at the other end of fourth bed board 114, through third connecting rod and base 13 pivot connection, when third bed board 113 overturns to certain angle, the other end of fourth bed board 114 can use the third connecting rod to overturn to a take the altitude as radius of rotation, and the length of third connecting rod is according to the concrete structural adjustment of bed body 1, and overlength or short can all lead to the unable upset lifting of the other end of fourth bed board 114. Therefore, the supporting mechanisms 12 in the bed body 1 can be reduced, the turning function of the bed plate 11 is not influenced, the weight of the bed body 1 can be reduced, the volume of the bed body 1 is reduced, and the production cost is reduced.

Further, the lengths and positions of the gravity arm, the first resistance arm and the second resistance arm in the horizontal direction of the support mechanism 12 in the extended state are adjusted according to the following equations (1) and (2) to reduce the length of the power arm in the vertical direction of the support mechanism 12 in the extended state:

F1＝(G×L3)÷L1 (1)；

L2>(F1×L4)÷F (2)；

wherein, the first resistance arm is above the second resistance arm.

The resistance F1 is a force perpendicular to the base 13 from the contact point of the second pulley 83 and the bed plate, the load G is a gravity perpendicular to the middle point of the bed plate contacted by the second pulley 83, the gravity arm L3 is a linear distance from the middle point of the bed plate contacted by the second pulley 83 to the rotation axis of the bed plate, the resistance arm L1 is a linear distance from the contact point of the second pulley 83 and the bed plate to the rotation axis of the bed plate, and the power arm L2 is a linear distance from the connection point of the support rod 81 and the second connecting rod to the extension line of the thrust F.

The length of the power arm L2 is proportional to the thickness of the support mechanism 12, i.e. the shorter the length of the power arm L2, the thinner the thickness of the support mechanism 12, and thus the thickness of the bed 1 is affected. For example, increasing the first resistance arm length, decreasing the gravity arm length to decrease the resistance, decreasing the second resistance arm length with decreasing resistance to further decrease the power arm length, and so on. When F <3000N, G >1285N, namely the bed bears the weight of a human body, the stress analysis is carried out to simulate and change the position of the force arm, calculate the change of the stress, find the optimal force arm, optimize the structure of the force arm of the bed body 1, reduce the thickness of the bed body 1 and thin the bed body.

The distance between the bearing part 31 and the opening is less than or equal to the thickness of the bed body 1, so that a larger storage space can be obtained. For example, set up bearing part 31 respectively in four corners of storing mechanism 3, the distance of bearing part 31 apart from the opening part equals the thickness of the bed body 1, just can put into the thing case opening with the bed body 1, has had the support of bearing part 31, and the bed body 1 can square put in storing mechanism 3 openings, also reduces the pressure that is in tilting mechanism 2 receives in the non-elevating state simultaneously, and the bed body 1 is put into storing mechanism 3 openings simultaneously, and is more pleasing to the eye on the whole.
