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.
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.

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 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.
