[0042] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present utility model, not all embodiments.

[0043] In the related art, a turning nursing bed is provided with a lifting mechanism and a turning mechanism under the bed frame. The lifting mechanism is used to drive the bed frame to move up and down, and the turning mechanism is used to drive the bed frame to turn around the front and rear axes. Currently, generally, the turning mechanism and the lifting mechanism are separated, making the turning mechanism and the lifting mechanism independent of each other, resulting in a relatively large space occupied by the turning mechanism and the lifting mechanism.

[0044] Based on this, the embodiments of the present utility model provide a turning nursing bed. The space occupied by the relevant components of the front lifter 100 and the front turning frame 300 is relatively small, leaving a relatively large remaining space under the bed frame 10, which is convenient for installing other functional devices.

[0045] Refer to Figures 1 to 5 As shown, the turning nursing bed of the present utility model includes a chassis, a bed frame 10, a front lifter 100, a front base 200, a front turning frame 300, a transmission assembly 400, and a driving mechanism 500.

[0046] The front lifter 100 is arranged on the chassis. The front base 200 includes an installation part 210 and a first connection part 220. The installation part 210 is connected to the front lifter 100. The first connection part 220 extends downward. The front lifter 100 drives the front base 200 to move in the up and down direction.

[0047] The front tilting frame 300 is hinged to the installation part 210, and the front tilting frame 300 rotates around an axis extending in the front and back direction.

[0048] The bed frame 10 is connected to the front tilting frame 300, and the front tilting frame 300 drives the bed frame 10 to rotate.

[0049] The transmission assembly 400 hinges the front tilting frame 300 and the installation part 210. The transmission assembly 400 extends downward, and the transmission assembly 400 extends below the front tilting frame 300.

[0050] The driving mechanism 500 hinges the transmission assembly 400 and the first connection part 220, and the driving mechanism 500 drives the transmission assembly 400 to approach or move away from the first connection part 220.

[0051] Refer to Figure 3 As shown, in this embodiment, the driving mechanism 500 drives the transmission assembly 400 to move rightward and approach the first connection part 220. Since the front base 200 is fixed to the front lifter 100, the position of the first connection part 220 is fixed. Then the transmission assembly 400 moves rightward. Since the transmission assembly 400 is hinged to the left end of the front tilting frame 300, and the middle part of the front tilting frame 300 is hinged to the installation part 210 of the front base 200, the front tilting frame 300 rotates around an axis extending in the front and back direction, that is, the left end of the front tilting frame 300 rotates downward and the right end of the front tilting frame 300 rotates upward, thereby driving the top surface of the bed frame 10 to flip rightward.

[0052] Refer to Figure 3 As shown, in this embodiment, the driving mechanism 500 drives the transmission assembly 400 to move leftward and away from the first connection part 220. Since the front base 200 is fixed to the front lifter 100, the position of the first connection part 220 is fixed. Then the transmission assembly 400 moves leftward. Since the transmission assembly 400 is hinged to the left end of the front tilting frame 300, and the middle part of the front tilting frame 300 is hinged to the installation part 210 of the front base 200, the front tilting frame 300 rotates around an axis extending in the front and back direction, that is, the left end of the front tilting frame 300 rotates upward and the right end of the front tilting frame 300 rotates downward, thereby driving the top surface of the bed frame 10 to flip leftward.

[0053] The front lifter 100 is connected to the installation part 210 of the front base 200. The first connection part 220 of the front base 200 extends below the front tilting frame 300. The transmission assembly 400 also extends downward below the front tilting frame 300. The driving mechanism 500 is arranged below the front tilting frame 300. The driving mechanism 500 is connected to the transmission assembly 400 and the first connection part 220, enabling the first connection part 220, the transmission assembly 400, and the driving mechanism 500 to utilize the vertical space between the bed frame 10 and the bottom frame, which helps reduce the horizontal width of the space occupied by the above components. The space occupied by the components related to the front lifter 100 and the front tilting frame 300 is relatively small, leaving a relatively large remaining space below the bed frame 10 for facilitating the installation of other functional devices.

[0054] In some embodiments, the front base 200 is further provided with a second connection part 230. The second connection part 230 also extends downward. The second connection part 230 is arranged on the front side of the front lifter 100, and the first connection part 220 is arranged on the rear side of the front lifter 100. The second connection part 230 is connected to the first connection part 220.

[0055] By connecting with the first connection part 220 and the second connection part 230, and the second connection part 230 and the first connection part 220 are respectively on the front and rear sides of the front lifter 100, it helps improve the strength of the front base 200 and prevent the front base 200 from being damaged.

[0056] In some embodiments, the turning nursing bed further includes a damper 600. The two ends of the damper 600 are respectively hinged to the transmission assembly 400 and the second connection part 230.

[0057] The driving mechanism 500 is used to drive the transmission assembly 400, and the damper 600 is used to slow down the impact during the rotation of the front tilting frame 300, which helps the front tilting frame 300 and the bed frame 10 rotate smoothly and avoid the bed frame 10 from rotating too fast.

[0058] In some embodiments, the first connection part 220 and the second connection part 230 have the same structure. The damper 600 is arranged on the front side of the front lifter 100, and the driving mechanism 500 is arranged on the rear side of the front lifter 100.

[0059] Reasonably arranging the damper 600 and the driving mechanism 500 on the front and rear sides of the front lifter 100 helps reduce the space occupied by the above components.

[0060] In some embodiments, the turning nursing bed further includes a connecting rod 240. The driving mechanism 500 is hinged to the connecting rod 240, and the connecting rod 240 is hinged to the first connection part 220 and the second connection part 230.

[0061] The first connecting portion 220 and the second connecting portion 230 are connected to the driving mechanism 500 by the connecting rod 240, which helps to disperse the pulling force and the pushing force of the driving mechanism 500 to the first connecting portion 220 and the second connecting portion 230.

[0062] In some embodiments, the turning nursing bed further includes a rear lifter 700, a rear base 800, and a rear turning frame 900. The rear lifter 700 is disposed on the chassis, the rear lifter 700 is disposed behind the front lifter 100, the rear base 800 is connected to the rear lifter 700, the rear turning frame 900 is hinged to the rear base 800, and the rotation axis of the rear turning frame 900 and the rotation axis of the front turning frame 300 are on the same straight line. The rear turning frame 900 is connected to the bed frame 10.

[0063] Setting the front lifter 100 and the rear lifter 700 to lift the bed frame 10 together helps the bed frame 10 to lift more smoothly. The rear turning frame 900 and the rear base 800 also support the bed frame 10, which helps to reduce the pressure on the front turning frame 300 and the front base 200.

[0064] In some embodiments, the bottom surface of the rear base 800 abuts against the top surface of the rear lifter 700, and the bottom surface of the mounting portion 210 abuts against the top surface of the front lifter 100.

[0065] The front lifter 100 is in surface contact with the mounting portion 210, and the rear base 800 is in surface contact with the rear lifter 700, increasing the contact area, which helps to reduce the pressure received by the front base 200 and the rear base 800 and prevent the front base 200 and the rear base 800 from being damaged.

[0066] In some embodiments, the transmission assembly 400 includes a first connecting rod 410 and a second connecting rod 420. The top of the first connecting rod 410 is hinged to the mounting portion 210, the top of the second connecting rod 420 is hinged to the front turning frame 300, the bottom of the second connecting rod 420 is hinged to the bottom of the first connecting rod 410, and the driving mechanism 500 is hinged to the second connecting rod 420.

[0067] Setting the first connecting rod 410 and the second connecting rod 420 to move below the front turning frame 300 can avoid interference between the driving mechanism 500 and the front turning frame 300.

[0068] In some embodiments, the transmission assembly 400 further includes a third connecting rod 430, a fourth connecting rod 440, and a linkage rod 450. The third connecting rod 430 and the fourth connecting rod 440 are disposed on the front side of the front lifter 100, the first connecting rod 410 and the second connecting rod 420 are disposed on the rear side of the front lifter 100. The top of the third connecting rod 430 is hinged to the mounting portion 210, the top of the fourth connecting rod 440 is hinged to the front turning frame 300, the bottom of the fourth connecting rod 440 is hinged to the bottom of the third connecting rod 430, and the second connecting rod 420 and the fourth connecting rod 440 are connected by the linkage rod 450.

[0069] A third link 430 and a fourth link 440 are arranged on the front side of the front lifter 100, a first link 410 and a second link 420 are arranged on the rear side of the front lifter 100, and the second link 420 and the fourth link 440 are connected by a linkage rod 450. While ensuring the smooth transmission of the transmission assembly 400, the structural strength of the transmission assembly 400 is improved.

[0070] In some embodiments, the top of the drive mechanism 500 is lower than the top of the front tilting frame 300.

[0071] Avoid the drive mechanism 500 protruding above the front tilting frame 300, causing the drive mechanism 500 to protrude above the bed frame 10 and damaging devices such as the mattress or bed board on the bed frame 10.
