Description

Technical Field

[0001] The invention relates to the field of multifunctional shelters, and in particular to a shelter sealing structure. Background Art

[0002] Field operation vehicles have multiple functions such as communication and support. The shelter is one of the main components of the field operation vehicle. Its shell strength meets the bulletproof standard. The door is the main channel for electromagnetic leakage in the cabin, and its performance is crucial to the overall shielding effectiveness of the shielding body. The cabin side door is mainly composed of the door body, door frame, hinge, locking mechanism, etc. The electrical connections between them and the rest of the cabin and all gaps need to be electromagnetically shielded to achieve effective shielding effectiveness. It should also have multiple functions such as air tightness, water tightness, and reliable usability.

[0003] In actual engineering practice, there are the following problems: 1. In the prior art, inflatable seals are generally used to seal the gaps between large doors and hatches. Such doors generally have a large circumference and are affected by the processing and assembly accuracy or by changes in ambient temperature, which can cause thermal expansion and contraction deformation, resulting in inconsistent or variable gaps that need to be sealed. The range of variation is generally 3-5mm or even larger. It is difficult to achieve an ideal sealing effect using ordinary sealing strips. In this case, a sealing product that can change with the gap is needed. Inflatable seals are a new type of sealing technology that has been successfully developed to meet such sealing requirements.

[0004] The existing inflatable seal, see CN210003806U, has an inflatable pipe on the clamping part, but the clamping part with the inflatable pipe cannot be clamped into the door. The patent does not design how to clamp the clamping part and how to disassemble and assemble the inflatable pipe with the sealing ring body. This leads to interference problems when installing the inflatable nozzle in actual work.

[0005] 2. The prior art of shelters is different from ordinary doors and door bodies. Since the shelter and the door meet bulletproof standards, there are many material layers, frames, and components. There is also a separate arm to drive the movement between the shelter and the door, which requires that the accuracy of multiple components meet the standards to achieve dimensional alignment. Thermal expansion and contraction deformation occurs due to the influence of processing and assembly accuracy or changes in ambient temperature. The thermal expansion and contraction properties of different materials are different or the processing accuracy is different, so there is a dimensional interference problem when assembling the components.

[0006] 3. The inflatable seal between the cabin body and the cabin door in the prior art is difficult to maintain when it needs to be maintained or inflated because it is stuck in the corner; if it is completely disassembled for maintenance, the time cost is too high.

[0007] Fourth, the inflatable seal between the cabin body and the cabin door in the prior art lacks a separate storage location for its corresponding maintenance parts, and there is no suitable tool box or space to store them. Summary of the invention

[0010] Preferably, the sealing body comprises a symmetric plane, and the connecting member is located on one side of the symmetric plane.

[0011] Preferably, the docking portion comprises a trapezoidal cross-section.

[0012] Preferably, a receiving cavity is provided on the hatch to accommodate the shielding rubber strip.

The space is close to the seal to facilitate the identification of the position and to facilitate storage and removal. BRIEF DESCRIPTION OF THE DRAWINGS
