Description

Technical Field

[0001] The utility model relates to the field of beds, in particular to an electric turning bed. Background Art

[0002] The turning bed in the prior art usually has two functions: lifting the back and turning over. The realization of the two actions of lifting the back and turning over is actually to transform the backboard, backboard and side flap from a horizontal state to an inclined lifting state. In the prior art, in order to realize this lifting action, a rotatable driving arm is often provided on the base of the turning bed, one end of the driving arm is rotatably connected to the base of the turning bed, and the other end is provided with a roller in contact with the lower surface of the backboard or the side flap. In this way, when it is necessary to lift up, the driving arm is rotated upward by a driving device (such as a motor, etc.), so that the roller slides along the lower surface of the backboard or the side flap, thereby lifting it upward. When the backboard and the side flap need to be changed from the lifting state to the horizontal state, the driving arm rotates downward, and the backboard and the side flap return to the horizontal state under the action of the external force thereon (such as the patient's own weight or the external force pressed by the assistant).

[0003] However, in the process of descending back to a horizontal state, if the external force is insufficient, the rollers may separate from the back plate and the side flaps. It is possible that the rollers have rotated to a horizontal state, but the back plate and the side flaps have not yet been lowered by the rollers and are in an unsupported suspended state. At this time, the assistant needs to apply a certain external force to the back plate and the side flaps to press them down to a horizontal state. Due to this unsupported suspended state, the back plate and the side flaps may suddenly fall to a horizontal state, resulting in a greater risk of impact and collision sound, affecting the safety, convenience and quietness of use.

DETAILED DESCRIPTION

[0022] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0023] As one aspect of the utility model, an electric turning bed is provided, comprising: a head 1, a foot 2, and a bed frame assembly 3 arranged between the head 1 and the foot 2, wherein the bed frame assembly 3 comprises a base 4, two side flaps 5 arranged side by side, and two back panels 6 arranged side by side, wherein the sides of the two back panels 6 close to each other are pivotally connected to a back panel connecting rod 7, and one end of the back panel connecting rod 7 facing the side flap 5 is pivotally connected to the base 4, and the side flap 5 and the back panel 6 located on the same side are pivotally connected, and the two side flaps 5 is pivotally connected to the base 4, and the base 4 is provided with a first electric push rod 8 for simultaneously pushing up or down the back plate connecting rod 7 and the back plate 6 when the side flap 5 is in a horizontal state, and a second electric push rod 9 for simultaneously pushing up or down the side flap 5 and the back plate 6 located on the same side when both the side flap 5 and the back plate 6 are in a horizontal state, the first electric push rod 8 and the second electric push rod 9 are perpendicular to the axis of the first electric push rod 8, and the axis of the first electric push rod 8 and the axis of the back plate connecting rod 7 are arranged in the same vertical plane.

[0024] The back plate 6 rotates around the axis A when the back is raised; the back plate 6 and the side flap 5 rotate around the axis B when they are turned over, and the axis A is perpendicular to the axis B.

[0025] Preferably, one end of the first electric push rod 8 is pivotally connected to the base 4, and the other end of the first electric push rod 8 is pivotally connected to the backboard connecting rod 7. The first electric push rod 8 is arranged along the longitudinal direction of the electric turning bed. When the first electric push rod 8 is retracted, the backboard connecting rod 7 and the two backboards 6 connected to the left and right sides thereof are pushed upwards together to achieve the back-lifting function. Conversely, when the first electric push rod 8 changes from being extended to being stretched, the backboard connecting rod 7 and the two backboards 6 connected to the left and right sides thereof are lowered downwards together until they are restored to a horizontal state.

[0026] Preferably, one end of the second electric push rod 9 is pivotally connected to the base 4, and the other end of the second electric push rod 9 is pivotally connected to the side flap 5. The second electric push rod 9 is arranged along the horizontal direction of the electric turning bed, and each side flap 5 is provided with a corresponding second electric push rod 9, through which the side flap 5 can be switched between the horizontal and inclined upward turning states. At the starting position of turning, the side flap 5 and the backboard 6 are both in a horizontal position. Since the backboard 6 is in a horizontal position, the first electric push rod 8 is in an extended state, so that the side flap 5 and the backboard 6 are located in the same plane, and a linkage structure is formed between the side flap 5 and the backboard 6. When the linkage structure is linked, the pivotable structure between the backboard connecting rod 7 and the side flap 5 makes the side flap 5 and the backboard 6 in the same plane, due to the rotation of the side flap 5, drive the backboard 6 connected thereto to turn synchronously in the same plane, so that the upper body of the user lying on the bed can be turned to the left or right. After the turning over is completed, the side flip plate 5 and the back plate 6 in the inclined state are synchronously dropped down to a horizontal state under the action of the second electric push rod 9.

[0027] More specifically, preferably, the back plate connecting rod 7 is provided with a first hinge part 10, and the back plate 6 is provided with a second hinge part 11 matched with the first hinge part 10. Preferably, the side flap 5 is provided with a third hinge part 12, and the base 4 is provided with a fourth hinge part 13 matched with the third hinge part 12. Preferably, the side flap 5 is provided with a fifth hinge part 14, and the back plate 6 is provided with a sixth hinge part 15 matched with the fifth hinge part 14. The above corresponding matching hinge parts can be connected through a hinge shaft.

[0028] Preferably, the bed frame assembly 3 further comprises a leg support assembly 16 disposed on the base 4, and the leg support assembly 16 is located on a side of the side flap 5 away from the backboard 6. The leg support assembly 16 may be a foldable structure with an upward bend to achieve an upward bending movement of the knee, which belongs to the prior art and will not be described in detail here.

[0029] Below, the use method and process of the utility model are described in detail.

[0030] The utility model comprises at least the following two functions, namely, back lifting and body turning.

[0031] Back-lifting function: When the back needs to be lifted, when the first electric push rod is retracted, the backboard connecting rod 7 and the two backboards 6 connected to the left and right sides thereof are pushed upwards at an angle to achieve the back-lifting function. Conversely, when the first electric push rod 8 changes from being extended to being extended, the backboard connecting rod 7 and the two backboards 6 connected to the left and right sides thereof are lowered downwards at an angle until they are restored to a horizontal state.

[0032] Turning over function: When turning over is required, the starting position of turning over is the position where both the side flap 5 and the backboard 6 are in a horizontal state. At the starting position, since the backboard 6 is in a horizontal position, the first electric push rod 8 is in an extended state, so that the side flap 5 and the backboard 6 are located in the same plane. Therefore, a linkage structure is formed between the side flap 5 and the backboard 6, that is, when the linkage is made, the backboard 6 can be turned synchronously in the same plane with the backboard 6 connected thereto due to the rotation of the side head flap 5 located on the same side, so that the upper body of the user lying on the bed can be turned over to the left or right. When turning over, the second electric push rod 9 contracts to turn the side flap 5 upwardly tilted. After turning over, the side flap 5 and the backboard 6 in the tilted state fall back synchronously downward to a horizontal state under the action of the second electric push rod 9.

[0033] In the above technical solution, the utility model uses the first electric push rod 8 and the second electric push rod 9 to realize the functions of back-raising and turning over. During the operation of these two functions, the tilted position of the side flip plate 5 and the back plate 6 is at a position determined by the telescopic length of the first electric push rod 8 and the second electric push rod 9, and the position is locked by the telescopic length of the first electric push rod 8 and the second electric push rod 9. Therefore, in the process of back-raising and turning over to restore to a horizontal state, the tilted position of the side flip plate 5 and the back plate 6 can be kept fixed in real time, and there will be no risk of being in an unsupported suspended state due to insufficient external force applied thereto, thereby causing a sudden fall to a horizontal state, thereby improving safety, convenience and quietness during use.

[0034] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
