[0028] When the rescue island is used, the push handle 4 on the upper end of the vehicle body 1 can facilitate the pushing of the vehicle body 1 so that the vehicle body 1 can be moved using the universal wheels 2 at the bottom. When rescue is needed, the electric unlocking button 14 on the upper side of the vehicle body 1 is pressed, and the electric unlocking button 14 controls the electromagnet 104 to be energized. After the electromagnet 104 is turned on, the signal can be transmitted to the first stepper motor 121 and the second stepper motor 126 through the single-chip microcomputer, thereby controlling the first stepper motor 121 and the second stepper motor 126 to turn on. The signal transmission control here has been disclosed in the software, and the transmission and reception of signals belong to the existing technology, which will not be described in detail here. After the first stepper motor 121 is turned on, it can use the gear to rotate the meshing transmission gear 122. After the transmission gear 122 rotates, the meshing first sector gear 123 can be used to drive the second sector gear 124 to rotate synchronously. After the first sector gear 123 and the second sector gear 124 rotate, the first linkage arm 125 can drive the first side door 6 to rotate and open. After the second stepper motor 126 is turned on, it can use the gear to make the third sector gear 127 drive the fourth sector gear 128 to rotate. After the third sector gear 127 and the fourth sector gear 128 rotate, they can drive the second linkage arm 129 to rotate. After the second linkage arm 129 rotates, The second side door 7 can be rotated and opened, and at the same time, the guide bearings 1210 at the bottom of the first side door 6 and the second side door 7 can move in the clamping groove 1211 on the door guide plate 1212, thereby improving the stability of the first side door 6 and the second side door 7 when rotating. A door locking block 1014 is installed on the first side door 6, and the door locking block 1014 is clamped in the clamping groove 1013 on the second lock buckle 1011. At this time, after the first side door 6 rotates, the door locking block 1014 can push the second lock buckle 1011 to rotate synchronously. After the second lock buckle 1011 rotates, it can push the connecting block 106, the guide rod 105 and the door opening rod 103 to move synchronously. When it is necessary to manually open the first side door 6 and the second side door 7, push the first side door 6 or the second side door 7 by hand. After the first side door 6 is pushed, the first linkage arm 125 at the bottom can reversely drive the second sector gear 124 and the first sector gear 123 to rotate, and after the second side door 7 is pushed, the second linkage arm 129 at the bottom can reversely drive the third sector gear 127 and the fourth sector gear 128 to rotate. In this way, the first side door 6 and the second side door 7 on the side of the vehicle body 1 can be manually opened. When the first side door 6 and the second side door 7 are opened, the first aid items placed on the internal tray 8 can be taken, and the internal oxygen cylinder 13 can be taken for use.

[0029] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. The overall design is a box-type design. When opening the door to take tools or place them, the overall design needs to occupy too much space. In order to further solve this technical problem, the following technical content is disclosed in this embodiment. The bottom of the connecting block 106 is interconnected with the drawer locking block 109 through a pin shaft 108. The drawer locking block 109 passes through the top plate 9 and is inserted into the bottom slot accommodating the drawer 5. The first side door 6 and the second side door 7 are both arranged as an arc structure. The upper ends of the first side door 6 and the second side door 7 are connected to the upper opening and closing component 10, and the lower ends of the first side door 6 and the second side door 7 are connected to the lower opening and closing component 12.

[0030] When the door opening pull rod 103 moves, it can drive the guide pull rod 105 at the end to move synchronously, and when the guide pull rod 105 moves, it can drive the connecting block 106 to move synchronously. Because the connecting block 106 and the drawer locking block 109 are interconnected by the pin shaft 108, when the connecting block 106 moves, the drawer locking block 109 can be pulled to rotate, so that the drawer locking block 109 rotates and disengages from the slot at the bottom of the accommodating drawer 5, thereby releasing the fixation of the accommodating drawer 5, and then facilitating the subsequent pulling out of the accommodating drawer 5. At the same time, the first side door 6 and the second side door 7 are both arranged to be arc-shaped. When in use, the side doors with an arc structure can minimize the occupied space of the vehicle body 1.

[0031] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
