Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an extended modified vehicle. Background Art

[0002] Fire command vehicles are often used in field exercises, flood relief, firefighting and rescue missions. Fire command vehicles are referred to as command vehicles. They are fire emergency rescue vehicles with communication, command, information processing and other functions. As a command center, they are mainly equipped with radio communication systems, TV monitoring systems, GPS positioning systems, voice recognition systems and high-definition video conferencing systems, etc., which can assist fire commanders in providing rapid information support and professional instructions in on-site decision-making;

[0003] Based on the above, during the use of traditional fire command vehicles, due to the fixed internal space, when commanding outdoors, the commander usually stands outside the vehicle to command. However, when encountering rainy weather, the command vehicle lacks a shielding device, making it very inconvenient for the commander to conduct outdoor command operations. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 6 , an expandable modified vehicle, whose structure includes a fire command vehicle 1 and an expansion mechanism 2 installed on the top of the fire command vehicle 1.

[0027] In this embodiment, the expansion mechanism 2 includes a driving device 21, an expansion plate 22 and a telescopic canopy 23. The driving device 21 is fixed to the top of the fire command vehicle 1, and the expansion plates 22 are symmetrically installed on the driving device 21. The bottom of the two expansion plates 22 are symmetrically installed with telescopic canopies 23 that can cover the expansion plates 22 twice through installation grooves.

[0028] In this embodiment, the driving device 21 includes a main frame 211, a rotating part 212, a pull rod 213, a fixed block 214 and a slide rail 215. The rotating part 212 is installed on the main frame 211, and the bottom of the rotating part 212 is connected to the control motor on the fire command vehicle 1. Both ends of the rotating part 212 are connected to the pull rod 213, and the other ends of the two pull rods 213 are connected to the fixed block 214. The bottom of the fixed block 214 is slidably matched with the slide rail 215 through a sliding seat. The slide rail 215 is located on the main frame 211 and fixed to the main frame 211.

[0029] In this embodiment, by controlling the motor to drive the rotating member 212 to rotate, the rotating member 212 can drive the two groups of pull rods 213 to rotate together, thereby driving the expansion plate 22 to move with the help of the two groups of pull rods 213, and the two groups of expansion plates 22 can be moved outward.

[0030] In this embodiment, the length of the pull rod 213 is greater than the width of the fire command vehicle 1 , so that the expansion plate 22 can be fully expanded to the outside of the fire command vehicle 1 under the action of the pull rod 213 .

[0031] In this embodiment, the telescopic shed 23 includes a mounting frame 31, a motor 32, a main shaft 33, a winding wheel 34, a rope 35, a base plate 36, a handle 37 and a telescopic cover 38. The mounting frame 31 is fixed to the expansion plate 22. The motor 32 is installed on the mounting frame 31. The output end of the motor 32 is connected to the main shaft 33. There are several winding wheels 34 arranged in an equidistant array on the main shaft 33. The several winding wheels 34 are all connected to ropes 35. The other ends of the several ropes 35 are connected to the base plate 36. A handle 37 is installed at the bottom of the base plate 36. A telescopic cover 38 is provided between the base plate 36 and the mounting frame 31. The telescopic cover 38 is located on the rope 35 and the telescopic cover 38 is connected to the base plate 36.

[0032] In this embodiment, the motor 32 drives a plurality of groups of winding wheels 34 to rotate in forward and reverse directions, so that the winding wheels 34 can drive the ropes 35 to be wound up and the telescopic cover 38 can be retracted or lowered.

[0033] Working principle: When the fire command vehicle 1 needs to be extended to block sunlight and rainy weather during outdoor use, the rotating member 212 is driven to rotate, and the rotating member 212 drives the two sets of pull rods 213 to move together on the slide rail 215 during rotation, so that the two sets of pull rods 213 drive the expansion plate 22 to move outward synchronously through the fixed block 214 during movement, until the expansion plate 22 is completely extended out of the body of the fire command vehicle 1 and stops;

[0034] Then, the main shaft 33 is driven to rotate by the motor 32, and several groups of winding wheels 34 are driven to rotate, so that the rope 35 wound in the winding wheel 34 can be extended, and the bottom plate 36 is driven to move downward. As the bottom plate 36 and the rope 35 move, the telescopic cover 38 will be driven to move downward and gradually expand until the telescopic cover 38 is fully opened and the rotation of the motor 32 is stopped. At this time, a shielding shed can be formed by the fully opened telescopic cover 38 and the expansion plate 22, which can block sunlight and rain, making it convenient for the fire command vehicle 1 to conduct safe command.
