[0027] The embodiment of the utility model provides an electric hospital bed 100 with an automatic lifting guardrail 131, please refer to Figure 1-3 The electric hospital bed 100 includes a bed frame assembly 110 , a bed board assembly 120 and a guardrail assembly 130 .

[0028] Please refer to Figure 1-2The bed frame assembly 110 includes an upper bed frame 111 and a lower bed frame 112, and the upper bed frame 111 is connected to the lower bed frame 112. The bed board assembly 120 is arranged on the upper bed frame 111, and the bed board assembly 120 is used to support the human body. The guardrail assembly 130 includes a guardrail 131, a connecting member 132 and a rotating driving member 133, and the connecting member 132 includes a first curved structure 1321, and the first curved structure 1321 has a first curved opening, one end of the first curved structure 1321 is rotatably connected to the upper bed frame 111, and the other end is rotatably connected to the guardrail 131. The rotating driving member 133 is arranged on the lower bed frame 112, and the output end of the rotating driving member 133 is rotatably connected to the guardrail 131, and the rotating driving member 133 is used to drive the guardrail 131 to move. When the guardrail 131 is at its lowest point in the vertical direction, the first curved opening is arranged toward the guardrail 131, and the height of the output end of the rotating driving member 133 in the vertical direction is higher than the height of the body of the rotating driving member 133, so that when the output end of the rotating driving member 133 moves, the first curved structure 1321 can drive the guardrail 131 to move up and down.

[0029] The guardrail assembly 130 of the utility model is provided with a first curved structure 1321 and a rotating driving member 133. The output end of the rotating driving member 133 moves between the guardrail 131 and the body of the rotating driving member 133, and can drive the guardrail 131 to move. When the height of the guardrail 131 in the vertical direction is at the lowest point, the first curved opening of the first curved structure 1321 is arranged toward the guardrail 131, and the height of the output end of the rotating driving member 133 in the vertical direction is higher than the height of the body of the rotating driving member 133, so that when the output end of the rotating driving member 133 pushes the guardrail 131 to move, the first curved structure 1321 can drive the guardrail 131 to move up and down, thereby adjusting the height of the guardrail 131 without manual adjustment, and is more convenient to use. Specifically, when the output end of the rotating driving member 133 contracts, the first curved structure 1321 drives the guardrail 131 to move downward. When the output end of the rotating driving member 133 extends, it can push the guardrail 131 to move. The guardrail 131 moves upward driven by the first curved structure 1321.

[0030] Please refer to Figure 2 The connecting member 132 also includes a first connecting rod 1322 , which is rotatably disposed on the upper bed frame 111 , and the first curved structures 1321 include two, one end of each of which is fixed to both ends of the first connecting rod 1322 .

[0031] In the embodiment of the utility model, two first curved structures 1321 and one first connecting rod 1322 are provided. Driven by the first connecting rod 1322 , the two first curved structures 1321 can move synchronously, so that the movement of the guardrail 131 is more stable.

[0032] Specifically, please refer to Figure 2 The connecting member 132 further includes a second connecting rod 1324 and a second curved structure 1323, and the second curved structure 1323 includes two. The second connecting rod 1324 is arranged on the upper bed frame 111 and is located above the first connecting rod 1322 in the vertical direction. One end of the two second curved structures 1323 is respectively fixed to the two ends of the second connecting rod 1324. More specifically, the curvature radius of the inflection point A of the first curved structure 1321 is smaller than the curvature radius of the inflection point B of the second curved structure 1323.

[0033] In the embodiment of the utility model, the curvature radius of the inflection point A of the first curved structure 1321 is smaller than the curvature radius of the inflection point B of the second curved structure 1323, which is beneficial for the first curved structure 1321 to apply force to drive the guardrail 131 to move upward. The second curved structure 1323 plays a role in assisting the movement of the guardrail 131, which can make the movement of the guardrail 131 more stable and smooth.

[0034] Please refer to Figure 2-3 The bed board assembly 120 includes a back board 121, a fixed board 122 and a leg board 123. The fixed board 122 is fixedly arranged in the middle position of the upper bed frame 111. The back board 121 and the leg board 123 are respectively arranged on both sides of the fixed board 122 on the upper bed frame 111. The back board 121 is used to support the back of the human body, the fixed board 122 is used to support the buttocks of the human body, and the leg board 123 is used to support the legs of the human body.

[0035] Please refer to Figure 3 The bed board assembly 120 further includes a third curved structure 124 having a third curved opening. One end of the third curved structure 124 is connected to one end of the back board 121 close to the fixed board 122, and the other end is connected to the upper bed frame 111. When the back board 121 is raised, the third curved opening is arranged away from the fixed board 122.

[0036] In this embodiment, the third curved opening is set away from the fixed plate 122, and one end of the third curved structure 124 is rotatably connected to the end of the back plate 121 close to the fixed plate 122, and the other end is rotatably connected to the upper bed frame 111. With such a design, when one end of the back plate 121 is raised, the end close to the fixed plate 122 has the third curved structure 124. The setting of the third curved opening away from the fixed plate 122 can reserve a certain space for the movement of the back plate 121, and the end of the back plate 121 close to the fixed plate 122 no longer makes a circular motion, thereby preventing the back plate 121 from pinching the hands or the back during the raising process.

[0037] Specifically, please refer to Figure 2-3The bed board assembly 120 includes a backboard driver 125, which is disposed on the upper bed frame 111, and an output end of the backboard driver 125 is rotatably connected to the backboard 121, and the backboard driver 125 is used to drive the backboard 121 to rise. The arrangement of the backboard driver 125 can facilitate the automatic rise of the bed.

[0038] Please refer to Figure 1 The bed board assembly 120 further includes a leg board driving member (not shown). The leg board 123 includes a thigh board 1231 and a calf board 1232. The end of the thigh board 1231 close to the fixed board 122 is rotatably connected to the upper bed frame 111, and the end of the thigh board 1231 away from the fixed board 122 is rotatably connected to the calf board 1232. The leg board driving member is disposed on the upper bed frame 111, and the output end of the leg board driving member is connected to the thigh board 1231, and the leg board driving member is used to drive the thigh board 1231 to rise.

[0039] In this embodiment, when the leg board driving member drives the thigh board 1231 to rise, the thigh board 1231 also drives the calf board 1232 to rise because the thigh board 1231 is rotatably connected to the calf board 1232. The rotation arrangement of the thigh board 1231 and the calf board 1232 can facilitate the patient to stretch and bend the legs.

[0040] The embodiment of the utility model further includes a remote controller (not shown), which is used to control the working state of the rotating driving member 133 , thereby realizing the raising and laying of the guardrail 131 .

[0041] Please refer to Figure 1 The embodiment of the utility model also includes universal wheels, which include four universal wheels. The four universal wheels are arranged on the lower bed frame 112 and are used to move the electric bed 100.

[0042] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
