Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to an expandable cabin structure for an emergency rescue command vehicle. Background Technology

[0002] As the core platform for on-site emergency command, the emergency rescue command vehicle needs to integrate multiple functional devices such as communication, monitoring, and conferencing within a limited onboard space. To obtain more internal working space when not in motion, existing command vehicles typically employ lateral or top-mounted expandable cabin structures. However, traditional expandable structures often use manual mechanical transmission or simple push-pull methods, resulting in laborious expansion operations, unstable processes, and poor positioning accuracy. In emergency rescue scenarios, rapid and reliable cabin deployment is crucial; any delay or instability can affect command efficiency. Furthermore, the airtightness and structural strength between the expandable cabin and the main cabin are also key to ensuring the normal operation of equipment and personnel safety. Therefore, a cabin structure capable of rapid, smooth, and automatic expansion with a robust structure is needed. Utility Model Content

[0003] (1) Technical solution To address the aforementioned technical problems, this utility model provides an expandable cabin structure for an emergency rescue command vehicle, comprising a main cabin, a first expandable cabin, a second expandable cabin, a first cylinder, a second cylinder, a first fixing plate, and a second fixing plate. The first expandable cabin and the second expandable cabin are respectively pull-out connected to one side and the other side of the main cabin. The first fixing plate and the second fixing plate are horizontally arranged on the upper and lower parts of the inner wall of the back of the main cabin, respectively. The first cylinder and the second cylinder are mounted on the middle part of the inner wall of the back of the main cabin, with one end of the first piston rod of the first cylinder facing the first expandable cabin. The second cylinder is connected to the inner wall of one side of the first expandable cabin. One end of the second piston rod of the second cylinder faces the second expandable cabin and is connected to the inner wall of one side of the second expandable cabin. A first guide rod is provided on the other side of the top of the first expandable cabin, a second guide rod is provided on the other side of the bottom of the first expandable cabin, a third guide rod is provided on the other side of the top of the second expandable cabin, and a fourth guide rod is provided on the other side of the bottom of the second expandable cabin. Guide grooves corresponding to the first guide rod, the second guide rod, the third guide rod, and the fourth guide rod are horizontally opened on the first fixing plate and the second fixing plate.

[0004] Preferably, the first guide rod, the second guide rod, the third guide rod, and the fourth guide rod are all T-shaped guide rods.

[0005] Preferably, the guide groove is a T-shaped groove.

[0006] Preferably, the main body has rectangular expansion openings on both sides that are adapted to the first expandable body and the second expandable body.

[0007] Preferably, both the first expandable cabin and the second expandable cabin are C-shaped.

[0008] Preferably, a sealing strip is provided at the position where the rectangular expansion port contacts the first expandable compartment and the second expandable compartment.

[0009] (2) Beneficial effects This utility model provides an expandable cabin structure for an emergency rescue command vehicle. Compared with the prior art, this utility model has the following advantages: 1. By setting cylinders as driving elements, the synchronous or independent deployment and retraction of the two side expansion chambers can be achieved simply by controlling the air source, which greatly reduces the labor intensity of operators and shortens the emergency response time.

[0010] 2. By setting guide grooves on the upper and lower fixing plates and precisely matching them with the guide rods on the expansion chamber, reliable guidance and support are provided for the expansion process, effectively preventing jamming, displacement or shaking of the chamber during movement, and ensuring structural stability and sealing effect after expansion into place.

[0011] 3. The combination of T-shaped guide rods and T-shaped slots not only ensures precise guidance but also enables the structure to withstand certain vertical and lateral loads, thereby enhancing the rigidity and integrity of the entire cabin structure in the extended state.

[0012] 4. A sealing strip is installed at the rectangular expansion port to ensure the airtightness of the connection between the main body and the expansion body after closing and expansion, effectively preventing water and dust, and protecting the working environment of the equipment inside the vehicle.

Detailed Implementation

[0017] The present invention will be further described in conjunction with the accompanying drawings and embodiments.

[0018] like Figures 1-3 As shown in this embodiment, an expandable cabin structure for an emergency rescue command vehicle includes a main cabin 1, a first expandable cabin 2, a second expandable cabin 3, a first cylinder 4, a second cylinder 5, a first fixing plate 6, and a second fixing plate 7. The first expandable cabin 2 and the second expandable cabin 3 are respectively pulled out and retracted from one side and the other side of the main cabin 1. To ensure a smooth and precise expansion process, the first fixing plate 6 and the second fixing plate 7 are horizontally arranged on the upper and lower parts of the inner wall of the back of the main cabin 1, respectively. The first cylinder 4 and the second cylinder 5 are installed on the middle part of the inner wall of the back of the main cabin 1. One end of the first piston rod 41 of the first cylinder 4 faces the first expandable cabin 2 and is connected to the inner wall of one side of the first expandable cabin 2. One end of the second piston rod 51 of the second cylinder 5 faces the second expandable cabin 3 and is connected to the inner wall of one side of the second expandable cabin 3. By controlling the movement of the cylinders, the two expandable cabins can be driven to extend and retract horizontally. A first guide rod 8 is provided on the other side of the top of the first expandable cabin 2, a second guide rod 9 is provided on the other side of the bottom of the first expandable cabin 2, a third guide rod 10 is provided on the other side of the top of the second expandable cabin 3, and a fourth guide rod 11 is provided on the other side of the bottom of the second expandable cabin 3. Guide grooves 12 are laterally opened on the first fixing plate 6 and the second fixing plate 7, corresponding to the first guide rod 8, the second guide rod 9, the third guide rod 10 and the fourth guide rod 11. These guide grooves 12 correspond one-to-one with the first guide rod 8, the second guide rod 9, the third guide rod 10 and the fourth guide rod 11 and slide in cooperation.

[0019] The first guide rod 8, the second guide rod 9, the third guide rod 10 and the fourth guide rod 11 are all T-shaped guide rods; the guide groove 12 is a T-shaped groove. This T-shaped fit structure can effectively prevent the guide rod from coming out of the guide groove and provides stronger torsional resistance and load-bearing capacity.

[0020] The main body 1 has rectangular expansion openings on both sides, which are adapted to the first expandable compartment 2 and the second expandable compartment 3. Both the first expandable compartment 2 and the second expandable compartment 3 are C-shaped so that they fit snugly against the side wall of the main body 1 when retracted, maximizing space saving. A sealing strip (not shown in the figure) is provided at the contact point between the rectangular expansion opening and the first expandable compartment 2 and the second expandable compartment 3. When the first expandable compartment 2 and the second expandable compartment 3 are fully retracted or extended, the sealing strip is compressed, thereby achieving a reliable seal between the main body 1 and the expandable compartments.

[0021] Working Principle: When expansion is required, the air supply is activated, and the first cylinder 4 and the second cylinder 5 operate simultaneously or separately, pushing the first piston rod 41 and the second piston rod 51 outwards. The piston rods drive the first expandable compartment 2 and the second expandable compartment 3 horizontally out of the rectangular expansion opening of the main compartment 1. During this process, each guide rod slides smoothly in its corresponding guide groove, ensuring that the expanded compartment moves in a straight line without jumping up and down or swaying left and right. When the expanded compartment reaches the predetermined position, the cylinder stops supplying air and locks itself, keeping the entire expansion structure stable. The retraction process is the reverse; the cylinder pulls the piston rod, smoothly retracting the expanded compartment into the main compartment. Content not described in detail in this specification is prior art known to those skilled in the art.

However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
