Description

Technical Field

[0001] This utility model relates to the field of amphibious vehicle technology, and in particular to an underwater drive mechanism for amphibious vehicles. Background Technology

[0002] Amphibious vehicles can travel in water and on land. The vehicle body must be completely sealed or have a watertight compartment to prevent water from entering and sinking. The buoyancy of the watertight compartment ensures the safe and stable travel of the amphibious vehicle in water. Amphibious vehicles use two sets of drive systems to achieve travel in water and on land.

[0003] Current amphibious vehicles often employ multiple underwater drive structures driven by relatively small motors, resulting in large space requirements and making them difficult to arrange and install. Furthermore, the motors are located underwater, placing high demands on their performance. For example, patent CN223224150U discloses an underwater drive device for an amphibious vehicle, comprising: a connecting assembly, a hydraulic telescopic rod, a plate, and two sets of drive assemblies. The connecting assembly is connected to the vehicle body; one end of the hydraulic telescopic rod is pivotally connected to the connecting assembly, and the other end is pivotally connected to the plate; the two sets of drive assemblies are symmetrically arranged on both sides of the plate, resulting in a complex structure and large space requirements. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an underwater drive mechanism for an amphibious vehicle, achieving a compact structure, small footprint, and ease of installation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The underwater drive mechanism of the amphibious vehicle includes a vehicle body, a drive motor, a transmission structure, and a propeller propulsion structure. The drive motor and the propeller propulsion structure are connected by the transmission structure. The vehicle body is a hollow structure with a groove at the bottom. The transmission structure and the propeller propulsion structure are both located in the groove, and the drive motor is located inside the vehicle body.

[0006] Further or preferred: The vehicle body is equipped with a chassis frame, and the drive motor is fixed to the chassis frame by a bracket.

[0007] The transmission structure includes a shaft tube and a transmission shaft located inside the shaft tube. The shaft tube is fixed in the groove by a shaft tube fixing seat.

[0008] The vehicle body has a mating hole at the inner end of the corresponding groove. The drive motor and the shaft tube are connected by a flange structure, and the flange structure is sealed to the mating hole.

[0009] The propeller propulsion structure includes a propeller and a propeller anti-collision frame, with the propeller located inside the propeller anti-collision frame and connected to the drive shaft.

[0010] The propeller anti-collision frame is connected to the shaft tube fixing seat.

[0011] A propeller baffle is provided behind the propeller.

[0012] Compared with the prior art, this utility model has the following advantages: The amphibious vehicle has a reasonable underwater drive mechanism design. The bottom of the amphibious vehicle is equipped with a groove, and the transmission structure and propeller propulsion structure are located in the groove. The drive motor is located inside the vehicle body. The structure is compact, occupies little space, is easy to arrange, and is stable and reliable. Attached Figure Description
