The invention provides a three-folding electric bed to solve the technical problem that the electric bed of the prior art has a large packaging size and cannot adapt to global logistics.

Figure 1 is a schematic diagram of the structure of a three-folding electric bed folding bed according to an embodiment of the present invention. As shown in Figure 1, a three-folding electric bed provided by the present invention includes: a first bed body 1, a second bed body 2 and The third bed body 3; wherein the first bed body 1, the second bed body 2 and the third bed body 3 are detachable and fixedly connected or rotatably connected at the junction; when the electric bed is horizontal When unfolded, the first bed body 1, the second bed body 2 and the third bed body 3 are at the same level; when the electric bed is folded, the first bed body 1, the second bed The body 2 and the third bed body 3 are folded in the thickness direction.

The volume of electric bed is generally larger than that of ordinary bed, and the transportation space cannot be fully utilized when it is directly packed and transported. Divide the electric bed into three independent parts, which can be detachably connected or revolved, such as drilling holes in the adjacent part of the bed, and then fixing the fasteners with better load-bearing performance through bolts To the adjacent bed bodies, the adjacent bed bodies are connected to form a completed electric bed. When it needs to be folded, only the fixing parts and bolts can be removed to fold the three together; another example is the hinge or pivot between the adjacent bed bodies. Connected, the adjacent beds can be rotated at least 180 degrees. When folding is needed, the first bed 1 and the third bed 3 are rotated 180 degrees in the opposite direction relative to the second bed 2, and are respectively folded on the second bed The top or bottom surface of the body 2; the detachable fixed connection and the rotatable connection can also be combined, and multiple bed bodies adopt different connection methods. When folded, the length of the electric bed is reduced to about one-third of that when it is spread horizontally, and the packaging size is also reduced. This breaks through the technical bottleneck that large-size electric beds cannot be transported by UPS, expands the scope of global distribution, and the overall packaging size It is best to meet the maximum size of length + 2 × width + 2 × height <420cm. By dividing the electric bed into three independent parts for folding, the length of the electric bed is reduced, the packaging size is reduced, the limited transportation space is fully utilized, the single transportation volume is increased, and the transportation cost is reduced.

Preferably, a detachable and fixedly connected bed body is used. After the half-folding is disassembled, it is better to add a connecting piece to fix the relative position of the folded bed body to prevent sliding between the two bed bodies and damage the bed body.

2 is a schematic structural diagram of a three-folding electric bed in an inverted state according to an embodiment of the present invention. As shown in FIG. 2, the first bed body 1 includes: a first support portion 101, a first base 102, and a first turning mechanism 103 The second bed body 2 includes: a second support portion 201 and a second base 202; the third bed body 3 includes: a third support portion 301, a third base 302, and a second turning mechanism 303; The first supporting portion 101 is provided on the top surface of the first base 102 and is pivotally connected, the first turning mechanism 103 is pivotally connected to the first base 102, and the first turning mechanism 103 can drive all The first supporting portion 101 is flipped relative to the first base 102; the second supporting portion 201 is disposed on the top surface of the second base 202; the third supporting portion 301 is disposed on the third base 302 The second turning mechanism 303 is pivotally connected to the third base 302, and the second turning mechanism 303 can drive the third support portion 301 relative to the third base 302 Flip.

The supporting parts are bounded by the boundary between the corresponding bases. When the supporting part in the first bed body 1 or the second bed body 2 is in a horizontal position, that is, the turning mechanism does not start to work, the turning mechanism is located between the corresponding supporting part and the base, and the base supports the supporting part. When the first turning mechanism 103 starts to work, push the first supporting part 101 to turn upwards relative to the first base 102 with the pivotal connection shaft of the first supporting part 101 and the first base 102 as the rotation axis; when the second turning mechanism 303 starts to work When pushing the third supporting part 301 to flip upward relative to the third base 302 with the pivotal connection axis of the third supporting part 301 and the third base 302 as the rotation axis; the position of the pivotal connection between the supporting part and the base can be selected and set according to the required flipping direction .

The first bed body 1 and the third bed body 3 are of modular design, which are not affected by the size of the second bed body 2 located in the middle of the electric bed, and can be combined in various ways. When you need to adjust the length of the bed body, you only need to adjust the length of the second bed body 2. There is no need to adjust the first bed body 1 and the second bed body 2, and the electric bed only needs to be adjusted between the three before and after folding. The connecting parts are convenient and quick.

Further, the third bed body 3 further includes a fourth supporting portion 304, and the fourth supporting portion 304 is pivotally connected to the third supporting portion 301.

At this time, only one turning mechanism is needed to drive the two support parts to turn over. Without adding a turning mechanism, more complex deformations can be completed to adapt to the human body curve, without increasing the volume and weight of the electric bed, and saving costs. It is beneficial to control the thickness of the electric bed, thereby controlling the packaging size.

Further, the third bed body 3 further includes a connecting rod 305, and two ends of the connecting rod 305 are pivotally connected to the fourth support portion 304 and the third base 302, respectively.

The connecting rod 305 can restrict the fourth support portion 304 from rotating around the connecting rod 305. When the third support portion 301 is turned to a certain angle, the fourth The end of the supporting part 304 pivotally connected with the third supporting part 301 will follow the flip, and the other end of the fourth supporting part 304 will be restricted and supported by the connecting rod 305 and will rise accordingly; the length of the connecting rod 305 will be adjusted according to the needs. If it is too long or too short, the other end of the fourth support portion 304 cannot be turned and raised. The fourth support portion 304 rotates to a certain height under the action of the connecting rod 305, which can better adapt to the human body curve and provide a more comfortable experience.
