Description

Technical Field

[0001] The utility model belongs to the technical field of amphibious equipment, and particularly relates to a vacuum cover and a cab of an amphibious equipment. Background Art

[0002] The sound insulation of the existing cab of amphibious equipment mainly depends on various forms of sound-absorbing sponges, which increases the vehicle body weight while reducing the buoyancy reserve of the amphibious equipment.

[0003] For example, the Chinese patent with the publication number CN115315366A discloses a separable cab device for an amphibious vehicle. The separable cab includes a housing for accommodating an operator, an independent floating system, and a separation device configured to separate the cab from the amphibious vehicle. Additional safety features are also provided to protect the operator in the separated cab from injury or to sustain life. However, this patent does not use a cover with a vacuum principle, and the floating system still uses sprayed foam, molded foam, or composite materials, and the cover has no sound insulation and buoyancy-increasing effects.

[0004] For example, the Chinese patent with the publication number CN204057737U discloses a shock-absorbing and noise-proof crane cab, which includes a noise-reducing damping housing. There is a rain shield on the top of the noise-reducing damping housing, double-layer sound-insulating glass on the front side and the left and right sides of the noise-reducing damping housing. There is a desiccant in the vacuum structure inside the double-layer sound-insulating glass, and there is a sealing rubber strip at the connection between the double-layer sound-insulating glass and the noise-reducing damping housing. There is a side door on the left side of the noise-reducing damping housing, and there is double-layer sound-insulating glass on the side door. There is a magnetic sealing strip between the side door and the noise-reducing damping housing. There is a double-layer floor at the bottom end of the noise-reducing damping housing. There is foam material in the middle of the double-layer floor, a noise-reducing pad on the upper side of the double-layer floor, and a rubber floor mat on the upper side of the noise-reducing pad. Shock-absorbing devices are arranged at the four corners on the lower side of the double-layer floor, including a circular concave cover plate, a circular concave bracket connected to the circular concave cover plate, a rubber shock-absorbing pad between the circular concave bracket and the circular concave cover plate, and a chassis under the circular concave bracket. However, this patent is not designed for amphibious equipment, has no buoyancy-increasing effect, and the housing is not designed with a vacuum structure, so it is not applicable to amphibious equipment.
