Specific implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0028] As Figures 1-3As shown in the figure, the specific structure of the present invention is: a mobile nursing bed, which includes a chassis 1 and wheels 2. The chassis 1 is connected to a bed base 5 through a support structure 4. A bed frame 6 is installed on the bed base 5. The bed frame 6 includes a fixed frame 21 and a movable frame 22. The support structure 4 is a structure that can electrically adjust the height of the bed base 5. A lifting structure 9 for lifting the movable frame 22 is provided on the bed base 5. A power distribution control module 10 is provided on the chassis 1. The lifting structure 9 and the support structure 4 are electrically connected to the power distribution control module 10. The power distribution control module 10 is equipped with a remote control. An obstacle avoidance block 3 is installed on the chassis 1. The obstacle avoidance block 3 is an arc-shaped block, and rotatable obstacle avoidance wheels are installed on the parts at the front and side of the chassis 1.

[0029] When the nursing bed of the present invention is specifically used, first place the mattress 7 on the bed frame 6. When a caregiver pushes the mobile nursing bed of the present application and needs to adjust the height for the convenience of the patient getting on and off the bed, the caregiver can transmit a signal to the power distribution control module 10 through the remote control. Then, the power distribution control module 10 will control the support structure 4 to drive the bed base 5 and the bed frame 6 to lift and lower as a whole. When the patient needs to lift the head, the caregiver can transmit a signal to the power distribution control module 10 through the remote control. Then, the power distribution control module 10 will control the lifting structure 9 to drive the movable frame 22 to rotate and lift. During the pushing process, if there are obstacles in the front or side, the obstacle avoidance wheels will be touched, thus avoiding the collision between the nursing bed and the obstacles. When specifically used, baffles 8 can also be provided on both sides of the bed base 5.

[0030] As Figure 3 As shown in the figure, the support structure 4 includes a support adjustment push rod 15 installed at the lower part of the chassis 1. The support adjustment push rod is connected to a support adjustment movable frame 16. Arc-shaped support rotating arms 17 are hinged at the four corners of the support adjustment movable frame 16. And the middle and lower parts of the support rotating arms 17 are installed on the side of the chassis 1 through a rotating shaft. The upper ends of the support rotating arms 17 are connected to a support frame 18. The support frame 18 is fixedly connected to the bed base. The support adjustment push rod 15 is electrically connected to the power distribution control module 10 and is remotely controlled by a remote control. The two support rotating arms 17 at the front or rear are installed on the same connecting rod of the support frame 18, and the upper ends of the two support rotating arms 17 at the front or rear are jointly connected to a fixed frame 21.

[0031] The specific use of the support structure 4 is as follows: When lifting and lowering adjustment is required, the support adjustment push rod 15 drives the support adjustment movable frame 16 to move. In this way, the support rotating arms 17 can rotate around the rotating shaft on the chassis 2, thus driving the support frame 18 to lift and lower, and further realizing the overall lifting and lowering of the bed base and the bed frame 6.

[0032] As Figure 4As shown, the lifting structure 9 includes a lifting connection block fixed on the movable frame 22. The lifting connection block is hinged with a lifting adjustment swing arm 25. The lifting structure 9 further includes a lifting adjustment push rod 26, and the body and the push rod end of the lifting adjustment push rod 26 are respectively hinged on the bed base 5 or the lifting adjustment swing arm 25. The number of the lifting connection block and the lifting adjustment swing arm 25 is two, and they are symmetrically arranged. The number of the lifting adjustment push rods 26 is two. The body of one of them is hinged on the bed base 5, and the body of the other is hinged on the lifting adjustment swing arm 25.

[0033] The lifting structure 9 adopts two lifting adjustment push rods 26, and the main bodies of the two lifting adjustment push rods 26 are located on the front and rear sides respectively. In this way, the front and rear quality and the left and right quality of the bed frame can be ensured to be balanced, and the movable frame 22 can be lifted from two points, so as to ensure the smoothness of the lifting.

[0034] As Figures 5-7 As shown, bed boards 23 are installed on both the fixed frame 21 and the movable frame 22, and both ends of the bed board 23 are connected with bed board installation blocks 32. Installation jacks 31 are opened on the fixed frame 21 and the movable frame 22. There are no less than two bed board installation plug posts 33 that can pass through the installation jacks 31 at the lower part of the bed board installation block 32. After the bed board installation plug posts 33 are installed, the length of the part passing through the installation jacks 31 exceeds 50 mm. A bed board installation plug block 34 is arranged on the bed board installation block 32, and a connection hole is opened on the bed board installation plug block 34. Bed board slots 35 are opened at both ends of the bed board 23, and connection plug rods that can be inserted into the connection holes are further arranged in the bed board slots 35.

[0035] The specific installation of the bed board is as follows. First, install the bed board installation blocks 32 on both sides of the bed board 23, sleeved the bed board slots 35 with the bed board installation plug blocks 34, and insert the connection plug rods into the connection holes. Then place the whole at the corresponding position of the movable frame 22 or the fixed frame 21, insert the bed board installation plug posts 33 into the installation jacks 31 and let them pass through, and the length of the part passing through exceeds 50 mm. In this way, in the case of use or lifting, the bed board installation plug posts 33 will not be separated from the installation jacks. If the bed board needs to be replaced, take out the whole of the bed board installation block and the bed board 23, and then separate the bed board installation block 32 from the bed board 23, then the replacement of the bed board can be realized.

[0036] As Figures 1-2 As shown, the power distribution control module 10 includes two power distribution control boxes 11 arranged on the front and rear sides of the chassis 1. The upper part of the power distribution control box 11 is conical, and the side surface of the conical part of the power distribution control box 11 is a heat dissipation mesh plate 12.

[0037] This application divides the power distribution control module 10 into two power distribution control boxes, so that the support structure and the lifting structure in the middle can be avoided without interference, and at the same time, it can play the role of power supply and control. Moreover, the design of the heat dissipation mesh plate 12 on the side of the conical part can ensure good heat dissipation operation.
