Description
Technical Field
[0001] The present invention relates to the technical field of unmanned vehicles (boats), and particularly to an amphibious variable-width unmanned vehicle (boat). Background Art
[0002] With the continuous development of technology, the application scenarios of unmanned vehicles (boats) are becoming more and more extensive. In some complex geographical environments, such as areas with both land and water, ordinary unmanned vehicles (boats) cannot meet the traffic requirements, so amphibious unmanned vehicles (boats) have emerged as the times require.
[0003] However, the existing amphibious unmanned vehicle (boat) body structures are relatively single, their adaptability to driving or sailing environments is poor, and their configurations and design methods have not kept up with the development of current technology. For example: the width of its vehicle (boat) body is generally fixed. When driving on land, a wider vehicle (boat) body may be restricted by narrow channels, reducing its passability; while when sailing on water, a narrower vehicle body will affect the driving stability, reducing its comprehensive sailing performance and economy. Summary of the Invention
[0004] The purpose of the present invention is to provide an amphibious variable-width unmanned vehicle (boat), which can adjust the width of the vehicle (boat) body according to different driving environments (land or water), and improve the traffic capacity and stability of the unmanned vehicle (boat) in different environments.
[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows.
[0006] The overall framework of a three-body amphibious unmanned vehicle (boat) is composed of a vehicle (boat) body structure (2), a vehicle (boat) body adjustment system (3), and an unmanned driving device and its control system (4).
[0007] The vehicle (boat) body structure (2) is characterized in that: the lower part of the vehicle (boat) body structure (5) is composed of three equally spaced parallel slender bodies connected horizontally, and the overall superstructure (6) forms the vehicle (boat) body structure (2).
[0008] The left and right slender bodies (7) of the lower part of the vehicle (boat) body structure (5) have exactly the same shape and scale, and the outer shape of the middle slender body (8) is similar to or exactly the same as that of the left and right slender bodies (7).
[0009] Each slender body is composed of a head, a middle section, and a tail.
[0010] The middle section of the slender body is a cylinder, and the cross-sectional shape of the cylinder is a semi-ellipse (9-1), or a composite shape of a semi-circle and a rectangle (9-2), or a composite shape of a semi-ellipse and a rectangle (9-3), or an approximate semi-ellipse (9-4), or an approximate composite shape of a semi-circle and a rectangle (9-5), or an approximate composite shape of a semi-ellipse and a rectangle (9-6).
[0011] The first section of the slender body gradually decreases in two equal proportions from the above-mentioned middle section cross-sectional shape along the length direction forward, and the tail section gradually decreases in two equal proportions from the above-mentioned middle section cross-sectional shape along the length direction backward, and the reduction ratio is a compound quadratic function or an approximate quadratic function law.
[0012] The maximum length L of the slender body is 1.2-7.8 meters, the maximum width B is 0.08-0.12L, and the maximum height H is 0.12-0.26L.
[0013] The integral superstructure (6) is a rectangular parallelepiped (10-1), or a column with an isosceles trapezoidal cross section (10-2), or a column with a polygonal cross section (10-3), or a column approximately rectangular parallelepiped (10-4), or a column approximately with an isosceles trapezoidal cross section (10-5), or a column approximately with a polygonal cross section (10-6).
[0014] The maximum length Ls of the integral superstructure (6) is 0.9-1.02L, the maximum width Bs is 0.3-0.5L, and the maximum height Hs is 0.18-0.26L. The land speed is 3-80km / h, and the water speed is 2-30km.
[0015] The vehicle (boat) body transverse width adjustment system is composed of a telescopic rod (11) and a control and execution system (12), wherein the telescopic rod (11) dynamically connects the outer slender body and the middle slender body (8).
[0016] The telescopic rods (11) are three sets in total and are respectively arranged at the front, middle and rear positions of the top of the middle sections of the three slender bodies, with one end of the telescopic rods being fixed to the inner and outer walls of the outer side bodies and the other end being fixed to the middle side bodies.
[0017] The cross section of the telescopic member is rectangular or arcuate, with an aspect ratio of 3--5 and a maximum width Bss of 0.03--0.06L; the control and execution system is arranged in the middle body.
[0018] The driving device of the vehicle (boat) and its control system are characterized in that the driving hardware device and its control hardware and software system constitute the driving device of the unmanned vehicle (boat) and its control system.
[0019] The described driving hardware device includes a land driving and a water navigation system.
[0020] The land driving hardware device (13) mainly consists of two sets of active caterpillar tracks or rolling wheels at the front and two passive wheels at the rear.
[0021] The caterpillar track driving device is arranged at the head of the middle section of the outer body, with about half inside the middle section and about half sinking outside (in contact with the ground).
[0022] The roller is arranged at the tail of the middle section of the outer body, with about half inside the middle section and about half sinking outside (in contact with the ground).
[0023] The active caterpillar track or rolling wheel consists of a motor and a rotating chain connecting the motor to the caterpillar track driving wheel or rolling wheel. The motor and the connecting chain are arranged on the bottom plate frame inside the middle section or the head section of the side body.

[0025] The unmanned driving (navigation) control software system is respectively arranged inside the superstructure and the side body.
[0026] The amphibious variable-width unmanned vehicle (boat) of the present invention can adjust the width of the vehicle (boat) body according to the driving environment and the type of goods carried through a width-changing mechanism. When the width is increased, the cargo hold capacity increases, the cargo volume is increased, and the economic benefit is improved.
[0027] When driving on land, reducing the width of the vehicle body enables it to easily pass through narrow passages, improving the passability of the unmanned vehicle on complex land terrains.
[0028] When driving on water, increasing the width of the vehicle (boat) body increases the stability of the unmanned vehicle (boat), reduces the risk of capsizing, improves safety, and also enhances the comprehensive navigation performance, thus further improving the economic efficiency.
