The bottom end of the main box shell 1 is fixedly connected to two auxiliary brackets 37, and the front and rear ends of the two auxiliary brackets 37 are provided with slope surfaces 38.

[0041] The first servo motor 16, the second servo motor 28 and the monitor in this embodiment are all conventional devices purchased on the market and known to those skilled in the art. They can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here.

[0042] In summary, the use process of the field nursing box for placing the monitor is as follows: when in use, the field nursing box for placing the monitor is first sorted and tested, and the power in the battery pack 36 is tested. If necessary, charging is required to ensure that the battery pack 36 has sufficient power supply. The charging of the battery pack 36 can be carried out by opening the operating cover 7, or a charging port can be installed on the main box shell 1. When the field nursing box for placing the monitor is carried by lifting, the overall structure of the field nursing box for placing the monitor is adjusted to the attached Figure 1 In the state shown, in this state, the contact plane 25 on the hand-held curved rod 5 and the contact plane 25 in the auxiliary handle bar 24 form mutual contact, so that the auxiliary handle bar 24 and the hand-held curved rod 5 form mutual coupling, which is convenient for the carrier to hold or connect and install relative to other supporting settings. When the field nursing box for placing the monitor is required to move automatically, the two first servo motors 16 are first operated separately to realize the rotation drive of the front rotating frame 8 and the rear rotating frame 9 relative to the main box shell 1, and then the front wheel frame 10 and the rear wheel frame 11 are rotated out of the main box shell 1, so that the main box shell 1 can be supported by the front wheel frame 10 and the rear wheel frame 11. Due to the setting of the notch surface 35, the track 12 in the front wheel frame 10 and the track 12 in the rear wheel frame 11 can be exposed, so the two tracks The belt 12 will be in contact with the placement location of the field nursing box for placing the monitor. After that, the two second servo motors 28 are powered on and can form a rotational drive of the support drive roller 27 through the transmission cooperation of the driving pulley 29, the driven pulley 30 and the synchronous belt 31. The rotation of the support drive roller 27 can form the drive of the crawler belt 12 connected thereto. Since the crawler belt 12 is in contact with the placement location, the moving crawler belt 12 can realize the active movement of the field nursing box for placing the monitor, and the differential movement between the two crawlers belts 12 is realized by controlling the coordinated movement of the two second servo motors 28, so as to form a change in the movement direction of the field nursing box for placing the monitor. Since the distance exposed by the crawler belt 12 from the corresponding notch surface 35 is long enough, it is more suitable for movement and operation in the field environment.

[0043] Furthermore, when in use, the operating cover 7 is opened relative to the cover body frame 6. The opening process of the operating cover 7 is to first pull the operating cover 7 relative to the cover body frame 6 so that the limiting protrusion 21 is completely withdrawn from the limiting recessed groove 22, and the limiting protrusion 21 is kept in a state of completely withdrawing from the limiting recessed groove 22, so that the operating cover 7 can be rotated and opened relative to the cover body frame 6, and then the monitor can be used. Since the two operating covers 7 are independent of each other, the two operating covers 7 can be opened separately to suit the usage conditions, reduce the opening width of the main box shell 1, ensure the use of the monitor while improving the protection effect, and must When necessary, the overall structure formed by the cover body frame 6 and the two operating covers 7 can be completely removed synchronously relative to the main box shell 1 to match the specific usage conditions and improve convenience during use. After use, the operating cover 7 is rotated in the opposite direction to realize the operation cover 7 relative to the cover body frame 6 to form a reverse rotation and closure relative to the cover body frame 6 when the operation cover 7 is opened, until the limiting protrusion 21 and the limiting recessed groove 22 rotate into a relative position, and the rotation limit is formed under the supporting action of the elastic spring 17 and the push frame 20, and the operating cover 7 can reach the limit after closing relative to the cover body frame 6.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
