FIG. 1 is a schematic diagram of an exemplary embodiment of an end cap for a medical bed. As shown in fig. 1, the hospital bed includes a frame 10 and a board 60, and the board 60 can move in a linear direction L and a reverse direction with respect to the frame 10. The end cap 20 is used to connect one end of the bed frame 10 in the linear direction L. The end cap 20 is positioned to avoid the path of movement of the deck 60 to avoid blocking the movement of the deck 60.

Fig. 2 is a schematic structural view for showing a view angle of the end cover and the bed plate of the hospital bed shown in fig. 1 in a direction opposite to the linear direction L. As shown in fig. 2, when the holder plate 60 moves to be opposite to the cover plate 20, a gap 80 penetrating in the linear direction L can be formed between the cover plate 20 and the holder plate 60 to prevent the holder plate 60 and the cover plate 20 from colliding with each other or being worn.

As shown in fig. 1 and 2, the end cap 20 includes a cap body 30 and two movable doors 40. The cover body 30 is used to connect the frame 10. The movable door 40 is rotatably coupled to the cover main body 30 and serves to form a partial gap 80. Fig. 2 is a broken line and fig. 3 shows a state in which the shutter 40 is rotated in addition to the state shown in fig. 1. In the present exemplary embodiment, the rotation axis of the shutter 40 with respect to the cover main body 30 is perpendicular to the linear direction L, so that the shutter 40 can change its projected area in the linear direction L by rotating, and thereby adjust the size of the gap 80 at the corresponding position. However, in other exemplary embodiments, the rotation axis of the movable door 40 relative to the cover main body 30 may be adjusted as needed, as long as the movable door 40 can change its projected area in the linear direction L by rotating, and thus adjust the size of the gap 80 at the corresponding position.

As shown in FIG. 1, when the end cap 20 is applied to a hospital bed, if a user's hand or object is inadvertently placed on the movable door 40, when the moving bed 60 hits or presses the hand or object, the movable door 40 is rotated to enlarge the gap 80 (i.e., to change from the state shown in FIG. 1 to the state shown in FIG. 3), so that the hit or pressed hand or object can be separated from the hospital bed through the enlarged gap 80, thereby reducing the damage. The end cover is applied to the medical bed, so that the use safety can be improved.

In the present exemplary embodiment, the two movable doors 40 correspond to the two receiving grooves 11 (only one of which is visible in fig. 1 and 3) of the frame 10. When the movable door 40 is in the state shown in fig. 1, the user's hand or article may further bypass the movable door 40 and be partially located in the receiving groove 11. When the moving bed plate 60 presses the hand or the object, the movable door 40 is rotated to enlarge the gap 80, so that the pressed hand or the object can be separated from the medical bed through the enlarged gap 80, thereby reducing the damage. Without limitation, in other exemplary embodiments, the gap 80 may be formed entirely by the moveable door 40, with the moveable door 40 not being located only at the most likely location of damage; and the number of the movable doors 40 can be adjusted as needed, for example, only one is provided.

As shown in fig. 1, in the present exemplary embodiment, the shutter 40 has an outer edge portion 41 for forming a partial gap 80. The moveable door 40 is moveable to a closed position (i.e., the position shown in fig. 1). Fig. 4 is a partial schematic structural view of the end cap of the hospital bed shown in fig. 1, showing the back side of the end cap shown in fig. 1. The cap body 30 has two pairs of stops 34 (only one of which is visible in fig. 4). A pair of stoppers 34 can abut against a movable door 40 in the closed position to prevent the outer edge portion 41 from rotating in a first rotating direction R1 toward the other end of the bed frame 10 in the linear direction L. When the movable door 40 is rotated in the second rotating direction R2 opposite to the first rotating direction R1, the gap 80 becomes larger at the corresponding position. Thereby preventing the user from pushing the movable door 40 in the first rotating direction R1 and inserting hands or articles into the medical bed to cause unnecessary damage. In other exemplary embodiments, the number, position and specific shape of the stoppers 34 may be adjusted as needed, and are not limited to those shown in the figures.

In the illustrated embodiment, the end cap 20 also includes two resilient members 50 (only one of which is visible in FIG. 4). An elastic member 50 applies force to the cover main body 30 and a shutter 40 to drive the shutter 40 to automatically return to the closed position, thereby simplifying the operation. In the present exemplary embodiment, the elastic member 50 is a tension spring, but is not limited thereto.

Referring to fig. 5, in the illustrated embodiment, each of the movable doors 40 has two pivot portions 42 extending in a direction parallel to the rotational axis thereof. The cover main body 30 has two pairs of pivoting portions 31 (only one of which is visible in fig. 5), and a pivoting portion 42 is rotatably inserted through one of the pivoting portions 31 through a pivoting hole 35 provided in the pivoting portion 31. Fig. 6 shows a schematic structural view of the pivot portion 42 and the pivot portion 31 along the rotation axis direction, wherein the pivot portion 42 and the pivot portion 31 are in a detached state. As shown in fig. 6, each pivot portion 42 has a cross section defined by two circular arc edges that are concentric and two straight edges that are parallel and of equal length. The circumferential side wall of each pivot portion 31 is opened with an opening 32 communicating with the pivot hole 35 to allow the pivot portion 42 to be detached from or attached to the pivot portion 31 through the opening 32 in a direction perpendicular to the rotation axis (i.e., from the bottom to the top in fig. 6). Thereby being convenient for the installation and the disassembly of the movable door. In other exemplary embodiments, the number of the pivoting portions 31 and the number of the pivoting portions 42 of each of the movable doors 40 may be adjusted as needed.

As shown in fig. 6, in the exemplary embodiment, the opening 32 is substantially trapezoidal, the caliber of the opening is gradually reduced in the direction perpendicular to the rotation axis, and the minimum caliber D2 is substantially equal to the distance D1 between two straight edges of the pivot portion 42, so that the pivot portion 42 and the pivot portion 31 are not easily separated during use. Without limitation, in other exemplary embodiments, the minimum diameter of the opening 32 in a direction perpendicular to the axis of rotation may be greater than the distance between two linear sides of the pivot portion 42; or the minimum caliber of the opening 32 in the direction perpendicular to the rotation axis is slightly smaller than the distance between two straight edges of the pivot part 42, the pivot part 31 is slightly deformed under the extrusion of an external force to allow the pivot part 42 to be assembled, so as to obtain better stability in use.

As shown in fig. 1, in the exemplary embodiment, the cap body 30 has a groove 33 that penetrates in the linear direction L. The recess 33 is used to accommodate the deck 60. The shutter 40 is disposed adjacent to the recess 33 and cooperates with the walls of the recess 33 to form a gap 80. Thereby being beneficial to the compactness of the medical bed.

The utility model also provides a bedstead subassembly of the medical bed, and the medical bed comprises a bed board 60. In an exemplary embodiment of a bed frame assembly, the bed frame assembly includes a bed frame 10 and an end cap 20 as shown in fig. 1.
