Technical Field

[0001] The invention relates to the technical field of vehicle-mounted mobile shelters, in particular to an automatically opening and closing emergency shelter. Background Art

[0002] Emergency shelters can arrive at designated sites during emergencies or wars to set up shelter command centers, field barracks, shelter hospitals, and communication emergencies, etc.

[0003] Emergency communication support is an important part of the national emergency management system. When communication network facilities are damaged, performance is degraded, or special communication support tasks such as national public security, especially public emergencies, etc. are involved, emergency communication plays an irreplaceable role.

[0100] In some embodiments of the present invention, the butt edges of the left movable top plate 61 and the right movable top plate 62 are provided with a first interlocking rainproof structure 300, comprising:

[0101] A first U-shaped tooth portion 301 is arranged on the lateral outer side of the left movable top plate 61, a second U-shaped tooth portion 302 is arranged on the lateral outer side of the right movable top plate 62 and engages with the first U-shaped tooth portion 301, a first burr 303 is arranged on the right movable top plate 62 and is placed on the outer side of the upper side of the second tooth portion, and a first sealing strip is embedded at the bottom of the first burr 303.

[0102] The top movable panel 60 of the present invention is composed of a left movable panel 62 and a right movable panel 62. When unfolding, the left and right movable panels 62 are separated, and when closed, the free ends of the left and right movable panels 62 are butted together to form the top movable panel 60. In order to prevent the rainproof effect after butting, a first U-shaped latching tooth portion 301 with an opening facing upward in a closed state is provided at the free end of the left movable panel 61, and the first U-shaped latching tooth portion 301 extends in the length direction to cover the longitudinal length of the edge of the left movable panel 61, and a second U-shaped latching tooth portion 302 with an opening facing downward in a closed state is provided at the free end of the right movable panel 62, and the second U-shaped latching tooth portion 302 covers the free end edge of the right movable panel 62 along its length direction. When unfolding, the right movable panel 62 is unfolded first, and then the left movable panel 61 is unfolded, and when closing, the left movable panel 61 is closed first, and then the right movable panel 62 is closed. In the closed state, the second U-shaped latching tooth portion 302 covers the first U-shaped latching tooth portion 301, and the two are engaged with each other to form a labyrinth seal, achieving a certain rainproof effect. In order to further improve the rainproof effect, a first burr 303 is fixed on the upper side of the free end of the right movable top plate 62, and the first burr 303 extends in the length direction to cover the second U-shaped latching tooth portion 302. When closed, the second burr 401 passes over the engagement position of the first and second latching tooth portions and covers the top surface of the left movable top plate 61. The first burr 303 plays a rainproof effect. Furthermore, a first sealing strip is fixed on the lower side of the first burr 303. When the first burr 303 is pressed on the left movable top plate 61, the first sealing strip is pressed tightly, forming a further seal. Of course, the left movable panel 30, the left movable top panel 61, the right movable panel 40 and the right movable top panel 62 are also provided with a third fin 402 at the edge relative to the front cabin module 20, a sealing strip is provided inside the third fin 402, and a ridge 404 is provided inside the side edge of the front cabin module 20 facing the rear movable panel, and a sealing strip can be preferably provided on the ridge 404. When closed, the third fin covers the front cabin module 20 from the outside, and the inner sides of the left and right movable panels 40 and the left and right movable top panels 62 are attached to the ridge, forming a sealing structure. The above sealing structure effectively protects the cabin from rain.

[0103] As an embodiment of the present invention, the tail of the left movable panel 30, the left movable top panel 61, the right movable panel 40 and the right movable top panel 62 are all provided with a second burr 401, which extends downward over the top of the rear movable panel 50 in the closed state, and a second sealing strip is fixed inside the second burr 401. After the panels are closed, the second sealing strip presses the rear cabin movable panel 50 to achieve a rainproof effect. A fourth burr 403 is provided on the upper edge corresponding to the left movable panel, and a fourth burr 403 is provided on the upper edge corresponding to the right movable top panel and the right movable panel, and the fourth burr 403 passes outward over the corresponding movable panels, achieving a certain rainproof effect.

[0104] The cabin body of the present invention can be opened and closed with one button, and the unfolding order of the left, rear and rear movable cabin panels is controlled by the control box program (of course, it can also be controlled manually), and a logical relationship is designed in the program; each action of each cabin panel is executed in place, and a signal is output to the control system through the limit sensor, and the control system executes the termination command.

[0105] When the cabin is opened, the right movable cabin board 40 is unfolded first, and then the left movable cabin board 30 is unfolded, and finally the rear movable cabin board 50 is unfolded. During the unfolding process, the right movable top board 61 is unfolded integrally with the right movable cabin board 40, and the left movable top board 61 is unfolded integrally with the left movable cabin board 30, and finally the rear movable cabin board 50 is unfolded. The present invention drives the opening and closing of the left, right and rear movable cabin boards by arranging a connecting rod mechanism on the left, right and rear movable cabin boards, so that the four sides of the entire cabin can be fully unfolded. Compared with the traditional sliding cover structure (the problem of insufficient maximum unfolding angle mentioned in the background technology), the unfolding angle is greatly improved, which greatly expands the use space of the cabin and realizes the maximization of the opening and closing of the cabin.

[0106] After the four panels (left, right, rear and top) are unfolded simultaneously, the interior space of the cabin is completely connected with the external environment, forming an unobstructed open platform that meets the needs of large-scale equipment deployment or multi-person collaborative work.

[0107] When all four sides are open, the air convection efficiency is improved, avoiding the heat accumulation problem in traditional closed cabins.

[0108] When unfolded on all four sides, it forms a 360° barrier-free entrance and exit.

[0109] And after unfolding on all four sides, especially when the left, right and rear decks are unfolded 90 degrees, they form the same plane with the bottom plate, greatly expanding the area of ​​the bottom operating platform.

[0110] When closing, the rear movable panel 50 is closed first, then the left movable panel 30 is closed, and finally the right movable panel 40 is closed. During the closing process, the left and right movable top panels are closed integrally with the left and right movable panels, respectively, and finally the complete closure of the cabin is achieved.

[0111] The cabin is installed as a whole on the chassis, so it can quickly reach areas where communications and other emergencies are needed.
