DETAILED DESCRIPTION OF THE EMBODIMENTS

(12) The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those having ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

(13) As shown in FIGS. 1-9, the bed structure includes the bedstead formed by the bedstead units (10). The bedstead units (10) are symmetrically arranged with respect to the central axis of the bedstead. The bedstead unit (10) includes the first bedstead unit (11) and the second bedstead unit (12). The first bedstead unit (11) is hinged to the second bedstead unit (12). The motor (20) is provided between the first bedstead unit (11) and the second bedstead unit (12). The bedstead units (10) at both sides of the central axis of the bedstead are hinged by the fixing rod (30). In this arrangement, the electric bed can be folded around the fixing rod (30) to form a single piece, as shown in FIG. 4. In addition, the first bedstead unit (11) can be tilted around the second bedstead unit (12) under the action of the motor (20) to form an inclined backrest in which users can comfortably sit and lie for reading and other behaviors, as shown in FIG. 1.

(14) Further, the bedstead unit (10) includes the support frame (13) and the bed board (14). The bed board (14) of the second bedstead unit (12) is fixedly connected to the support frame (13). The bed board (14) of the second bedstead unit (12) acts as the fixing member, so that the bed board (14) of the first bedstead unit (11) can be lifted around the hinge point between the first bedstead unit (11) and the second bedstead unit (12) under the action of the motor (20) to form the backrest.

(15) Further, the bed board (14) includes the outer frames (15) and the support bar (16) arranged between the outer frames (15). Specifically, the second bedstead unit (12) is fixed to the support frame (13), wherein, the support frame (13) is provided with the first fixing member (41) that is fixed to the outer frame (15) of the second bedstead unit (12), and the support frame (13) is provided with the second fixing member (42) that is fixed to the support bar (16) of the second bedstead unit (12). The fixed connecting rod (43) is provided between the support frame (13) and the first bedstead unit (11). The support frame (13) is fixed in the longitudinal and horizontal directions to ensure the stable connection between the support frame (13) and the second bedstead unit (12). Moreover, the fixed connecting rod (43) is configured to improve the stability of the rotation between the first bedstead unit (11) and the second bedstead unit (12) and significantly reduce the force applied on the hinge point between the first bedstead unit (11) and the second bedstead unit (12).

(16) Further, the bed board (14) is provided with the latticed support columns (17). The latticed support columns (17) are integrated to form a support surface, avoiding the multiple disassembly and assembly processes. A cotton mattress can be directly placed on the support surface.

(17) Further, the clamping member (31) is provided at both ends of the fixing rod (30). The support frame (13) is provided with the matching member (50), which is matched with the clamping member (31). The clamping member (31) and the matching member (50) are hinged by a fastener. In FIG. 7, the position indicated by C is the hinge point of the fastener. In the embodiment of the present invention, the fastener is a rivet, or the like.

(18) Further, the clamping member (31) is provided with the positioning column (32). In FIG. 7, the positioning column (32) is arranged at the position D. The matching member (50) is provided with the arc-shaped groove (55) that is matched with the positioning column (32). The arc-shaped groove (55) includes the first notch (51) and the second notch (52). The first notch (51) is configured to position the clamping member (31) through the positioning column (32), and the second notch (52) is configured to avoid jamming in the course of folding the bedstead unit (10). The arc-shaped protrusion (53) is provided between the first notch (51) and the second notch (52). The arc-shaped groove (55) is arranged so that the bedstead units (10) at both sides of the fixing rod (30) can be seamlessly attached to each other by a relatively short rotational distance. Specifically, the side end surface of the first notch (51) is a vertical surface. The side end surface of the second notch (52) and the matching surface of the second notch (52) are straight surfaces. The first notch (51) and the second notch (52) are designed to avoid jamming when the bedstead unit (10) is rotated and folded around the fixing rod (30), so that the bedstead units (10) at both sides of the fixing rod (30) can be seamlessly attached to each other, as shown in FIG. 4. In use, the support frame (13) is unfolded, the positioning column (32) is clamped in the first notch (51) for positioning, as shown in FIG. 8 or FIG. 9. In the folded state, the bedstead units (10) at both sides of the fixing rod (30) are folded into one piece, and the positioning column (32) is clamped in the second notch (52). During the folding process, the arc-shaped protrusion (53) provided on the matching member (50) allows the second notch (52) to slide into and fit into the positioning column (32).

(19) During use, users can regulate and control the motor (20) by a control device, so that the first bedstead unit (11) can be tilted as a backrest or a footrest, and can also be folded integrally when the bed board (14) is horizontal, thus reducing the occupation of space.

(20) The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be construed as an exclusion from other embodiments, and can be used in various other combinations, modifications, and environments, and can be modified within the scope of the present invention described herein according to the above teachings or technologies or knowledge in the related field. Modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the scope of protection of the appended claims of the present invention.
