All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

The following is an example of a possible embodiment of the present invention, and does not limit the scope of the present invention, as illustrated in .

Referring to fig. 1 to 8, which illustrate an embodiment of the present invention, the bed structure of the present invention includes a bed frame 1 and a supporting mechanism 2.

The bed frame 1 includes a first side 11 and a second side 12 opposite to each other, the first side 11 is defined as a first direction 91, and the second side 12 is defined as a second direction 92. The supporting mechanism 2 can swing to a first position and a second position, the supporting mechanism 2 includes at least one first supporting member 21 and at least one second supporting member 22, the at least one first supporting member 21 is corresponding to the upper half of the human body, the at least one second supporting member 22 is corresponding to the lower half of the human body, and the at least one first supporting member 21 and the at least one second supporting member 22 can be pivotally arranged on the bedstead 1 and are both in a curved shape. When the supporting mechanism 2 is located at the first position, the at least one first supporting member 21 and the at least one second supporting member 22 do not protrude from the first side surface 11, and the direction of the bending opening of the at least one first supporting member 21 faces the first direction 91; when the supporting mechanism 2 is located at the second position, the at least one first supporting member 21 and the at least one second supporting member 22 swing relatively to each other to approach and protrude from the first side surface 11.

More specifically, the bed structure preferably further comprises a cushion unit 3 disposed on the first side surface 11 for supporting a human body in a large range, when the supporting mechanism 2 is located at the first position, the at least one first supporting member 21 and the at least one second supporting member 22 do not push against the cushion unit 3, the cushion unit 3 is disposed on the first side surface 11, and the bed structure allows a user to lie flat and stretch his body, and the cushion unit 3 is supported by the bed frame 1. When the supporting mechanism 2 moves from the first position to the second position, the at least one first supporting member 21 and the at least one second supporting member 22 push the cushion unit 3 to move in conjunction, so that the cushion unit 3 deforms with the actuation of the at least one first supporting member 21 and the at least one second supporting member 22, and at this time, the user can lie on the cushion unit 3 in a semi-lying and semi-sitting posture to perform other actions, such as: reading books, eating meals, etc.

It should be particularly noted that when the supporting mechanism 2 is located at the second position, the at least one first supporting member 21 with the upward bending mouth can make the cushion unit 3 bend to conform to the curved contour of the back (spine) of the human body, so as to firmly abut against and support the back, and make the muscles of the upper half of the human body supported and relaxed sufficiently, thereby improving the comfort of the user when sitting and lying, and further making the user lie for a long time. Meanwhile, the at least one second support member 22 can support the user's thighs to relax the natural slight bending. Therefore, the bed body structure is very suitable for the people who are inconvenient to move or need to be taken care of and lie on the bed for a long time.

More specifically, the bed structure further includes a power unit 41, a first rotating rod 51, a second rotating rod 52, at least one first pushing component 6 and at least one second pushing component 7, the first rotating rod 51 is pivoted to the bed frame 1 and is controlled by the power unit 41 to rotate, the at least one first pushing component 6 is connected to the first rotating rod 51 to rotate together, and a portion of the at least one first pushing component 6 is located below the at least one first supporting component 21 to push and support the swinging of the at least one first supporting component 21. In short, the power unit 41 drives the first rotating rod 51 to rotate, so that the first pushing component 6 rotates around the first rotating rod 51, the first pushing component 6 pushes the first supporting member 21 upwards during the rotation, and finally the first supporting member 21 pushes the cushion unit 3 to move and bend towards the first direction 91. Similarly, the second rotating rod 52 is pivotally connected to the frame 1 and is controlled by the power unit 41 to rotate, the at least one second pushing component 7 is connected to the second rotating rod 52 to rotate, and a portion of the at least one second pushing component 7 is located below the at least one second supporting component 22 for pushing the at least one second supporting component to swing.

In this embodiment, a tangent line at the most curved portion of each first supporting member 21 forms a first included angle with the first side surface 11, a tangent line at the most curved portion of each second supporting member 22 forms a second included angle with the first side surface 11, the first included angle is greater than the second included angle, the first included angle is between 40 degrees and 90 degrees, and the second included angle is between 5 degrees and 40 degrees. The power unit 41 includes two electric motors 411, and the two electric motors 411 are respectively connected to the first rotating rod 51 and the second rotating rod 52, it can be understood that the two electric motors 411 can be integrally formed as in the present embodiment, and in other embodiments, the two electric motors 411 can be independently separated or not. The supporting mechanism 2 is driven by the power unit 41 to move between the first position and the second position, so that the burden of users and other people can be effectively relieved, the supporting mechanism is very suitable for people with weak body (such as old people and patients), the people can freely lie flat or lie half flat and sit, the supporting mechanism 2 can assist the body to gradually move in the moving process, and the situation that the body is stiff due to the fact that the body maintains a fixed posture for a long time is avoided.

More specifically, the supporting mechanism 2 further comprises a neck supporting frame 24, the neck supporting frame 24 is pivotally connected to the at least one first supporting member 21, so that the neck supporting frame 24 can support the neck of the user when the user sits on the seat and lies on the seat. In order to actually drive and provide a supporting force to the head and neck supporting frame 24, each of the first pushing assemblies 6 includes a seat body 61, a first main pushing member 62, a first auxiliary pushing member 63 and a first rolling member 64, the seat body 61 is positioned on the head and neck supporting frame 24, one end of the first main pushing member 62 is positioned on the first rotating rod 51, the first auxiliary pushing member 63 is respectively pivoted to the other end of the first main pushing member 62 and the seat body 61, so that the head and neck supporting frame 24 has a swing margin, and when the head and neck supporting frame 24 is pressed by the user, the head and neck supporting frame can tilt backwards (see fig. 8), so that the user can move the neck to avoid stiffness. In addition, the first rolling member 64 is positioned on one of the first main pushing member 62 and the first supporting member 21 and selectively rolls against the other, and the first rolling member 64 can enable the first main pushing member 62 to smoothly push the first supporting member 21 to move upward and pivotally, and can provide a supporting force to the first supporting member 21.

More specifically, the supporting mechanism 2 further includes at least one third supporting member 23, the at least one third supporting member 23 is correspondingly pivoted to the at least one second supporting member 22, so that when the user is half seated or lying down, the at least one third supporting member 23 can further suspend and lift the lower leg of the user to maintain a certain height so as not to suspend to the ground, wherein a node 231 is defined at a position where the second supporting member 22 and the third supporting member are pivoted to each other.

In the present embodiment, when the first side surface 11 is viewed along the second direction 92, the lengths of the supporting members are, in order from long to short, the first supporting member 21, the third supporting member 23 and the second supporting member 22. When the supporting mechanism 2 is located at the first position, the direction of the curved opening of the at least one second supporting member 22 is toward the first direction 91, so as to continue the contour of the at least one first supporting member 21 and to support the buttocks and thighs of the human body, so that the thighs are placed upward, the at least one third supporting member 23 is preferably curved, and the direction of the curved opening of the at least one third supporting member 23 is toward the second direction 92, so that the lower abdomen can be supported, so that the lower abdomen can be relaxed and naturally hung. Moreover, since the at least one first support member 21, the at least one second support member 22 and the at least one third support member 23 are curved structures, when tilting, the curved portions are naturally and smoothly curved, and even if the cushion unit 3 with a small thickness is selected, the user will not feel sharp and stabbing feeling and can comfortably lie down on the cushion unit 3.

Of course, the directions of the curved openings of the second supporting member 22 and the third supporting member 23 are not limited to the above, but may be configured in any reverse direction as required. For example, but not limited to, referring to fig. 9, when the supporting mechanism 2A is located at the first position, the direction of the curved opening of the at least one second supporting member 22A and the direction of the curved opening of the at least one third supporting member 23 are towards the second direction 92.

It should be noted that when the supporting mechanism 2 moves from the first position to the second position, the second roller 73 can be lifted smoothly and provide a supporting force to the third supporting member 23, and the second sub-pushing member 72 can drive the second supporting member 22 and the third supporting member 23 to operate simultaneously by applying a force to the node 231, so as to have a better synchronous operation effect. Moreover, the second sub-pushing member 72 supports the node 231, so as to further enhance the structural stability thereof to resist external force, so that the second supporting member 22 and the third supporting member 23 can be kept at fixed positions without shaking or folding due to the weight of the user.

Specifically, the second main pushing member 71 includes a first section 711 and a second section 712, the first section 711 is connected to the second rotating rod 52, the second roller 73 is disposed on the second section 712, the first section 711 is obliquely connected to the second section 712 and is substantially "v" -shaped, one end of the second sub-pushing member 72 is pivotally connected to the connection between the first section 711 and the second section 712, and when the supporting mechanism 2 is located at the second position, the second main pushing member 71 and the second sub-pushing member 72 are substantially "y" -shaped. Wherein the length of the second secondary pusher 72 is half the length of the second section 712.

It should be noted that, in the present embodiment, the pivotable elements of the bed structure (such as the first supporting member 21, the second supporting member 22, the head and neck supporting frame 24 …, etc.) are all pivoted to each other through a pivot ear structure 8 in a shape of "ㄩ", so as to facilitate quick assembly and have better structural strength.
