Description

Technical Field

[0001] This invention belongs to the field of marine equipment technology, specifically relating to a propulsion appendage device and propulsion method for amphibious vehicles navigating on water. Background Technology

[0002] With the continuous development of my country's water transportation and navigation technology, the demand for exploring more types and methods of maritime transportation is constantly expanding. Amphibious vehicles, as an emerging force in maritime navigation, are increasingly attracting attention. Currently, most amphibious vehicles face the problem of insufficient propulsion power when navigating water, lacking conventional solutions and exhibiting significant shortcomings in energy conversion efficiency. This hinders their widespread application in real-world marine environments. Therefore, there is still considerable room for improvement in the propulsion power of amphibious vehicles. Consequently, a practical and convenient device and method are needed to enhance the effective conversion of energy power and achieve relatively higher propulsion power for amphibious vehicles during water navigation. Summary of the Invention

[0003] The purpose of this invention is to provide a propulsion attachment device and propulsion method for amphibious vehicles to navigate on water. By using an arc-shaped baffle with a partition on the inner side, the impact force difference between the upper and lower rims of the drive wheel is adjusted, thereby improving forward propulsion.

[0004] To achieve the above objectives, the present invention provides a propulsion attachment device for amphibious vehicle navigation on water, including an arc-shaped baffle covering the drive wheel of the amphibious vehicle, wherein a plurality of spaced partitions are provided on the side surface of the arc-shaped baffle facing the drive wheel.

[0005] Furthermore, the upper surface of the arc-shaped baffle is movably connected to the fender of the amphibious vehicle to adjust the distance between the arc-shaped baffle and the drive wheel.

[0006] Furthermore, the arc-shaped baffle is movably connected to the fender via a telescopic assembly, and the connection point is located at the middle part of the upper surface of the arc-shaped baffle.

[0007] Furthermore, the arc-shaped baffle is also provided with a circumferential length adjustment component, which is used to adjust the arc length of the arc-shaped baffle, thereby adjusting the circumferential coverage range of the arc-shaped baffle on the drive wheel.

[0008] Furthermore, the circumferential length adjustment component is a telescopic plate structure.

[0009] Furthermore, the partitions are arranged at equal intervals, and preferably the surface of each partition passes through the center of the drive wheel.

[0010] Furthermore, the arc-shaped baffle covers one-third to one-half of the circumference of the upper rim of the drive wheel.

[0011] Furthermore, horizontal thin plates are provided at both ends of the arc-shaped baffle.

[0012] The present invention also provides an amphibious vehicle, including any of the above-described propulsion attachment devices.

[0013] The present invention also provides a propulsion method for the above-described amphibious vehicle's waterborne navigation, comprising: adjusting the difference in water flow impact force on the drive wheel by adjusting the distance and arc length between the arc-shaped baffle and the amphibious vehicle's drive wheel, thereby adjusting the magnitude of the propulsion force. Specifically, the propulsion force is increased by reducing the distance between the arc-shaped baffle and the amphibious vehicle's drive wheel and / or increasing the arc length of the arc-shaped baffle.

[0014] In summary, compared with the prior art, the above-described technical solutions conceived by this invention mainly possess the following technical advantages:

[0015] 1. This invention utilizes an arc-shaped baffle with an inner partition covering the drive wheel. This creates a flowable space between the inner groove of the arc-shaped baffle and the upper rim of the drive wheel. Within this flowable space, the drive wheel generates a water channel. The impact force of the water flow on the lower rim remains largely unchanged. However, due to the presence of vertical partitions within the water channel, the impact force of the water flow on the upper rim is partially offset by the vertical partitions, thus increasing the impact force difference between the upper and lower rims and consequently enhancing the amphibious vehicle's forward propulsion on water. Simultaneously, it does not affect the vehicle's original driving capabilities when traveling on land, optimizing the conversion between amphibious and water-based uses and effectively solving the problem of insufficient power during amphibious vehicle navigation.

[0016] 2. This invention uses a telescopic component and a circumferential length adjustment component to drive the vertical and circumferential movement of the arc-shaped baffle, thereby adjusting the size of the flow space formed between the arc-shaped inner groove of the water flow baffle and the drive wheel rim. This changes the resistance in the flow channel through which the water flows, thereby increasing the forward power of the device and realizing the effective conversion of energy power.

[0017] 3. The present invention improves the balance and stability of the water flow boost by arranging the partitions at equal intervals; the horizontal thin plates at both ends of the arc-shaped baffle facilitate the guidance of water flow into the flowable space formed between the inner groove of the arc-shaped baffle and the wheel rim of the drive wheel, thereby improving the boosting effect.

[0018] 4. This invention only adds a booster attachment device, without changing the original shape and motion characteristics of the amphibious vehicle, maintaining its original land driving ability and efficiency, and reducing the economic costs required for the amphibious vehicle.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1

[0025] Please see Figure 1 and 2 This invention provides a propulsion attachment device for amphibious vehicle navigation, including an arc-shaped baffle 2 covering the drive wheel of the amphibious vehicle. The surface of the arc-shaped baffle 2 facing the drive wheel has a plurality of spaced-apart partitions 3. The arc-shaped opening of the arc-shaped baffle 2 faces the drive wheel. The side of the arc-shaped baffle 2 facing the drive wheel is referred to as the inner surface, and the side facing away from the drive wheel is referred to as the upper surface.

[0026] With this configuration, when the amphibious vehicle is navigating on water, the drive wheels are submerged. The motor's rotation stirs the water on the uneven surfaces of the drive wheel rims, creating a current. The impact force on the upper and lower rims is approximately equal in magnitude but opposite in direction, resulting in an overall impact force difference. After the curved baffle of the booster attachment covers the upper rim of the drive wheel, a flowable space is formed between the baffle and the upper rim. The drive wheel creates a flow channel within this space. The impact force on the lower rim remains largely unchanged, while the impact force on the upper rim is partially offset by the vertical baffles within the flow channel. This increases the impact force difference between the upper and lower rims. By altering the vertical distance between the baffle end and the circumference of the drive wheel, as well as the length of the flow channel, the overall impact force difference can be enhanced, thus solving the problem of insufficient forward propulsion for the amphibious vehicle while navigating on water.

[0027] Specifically, the baffles 3 are arranged at equal intervals, preferably with the surface of each baffle 3 passing through the center of the drive wheel. The baffles 3 are arranged along the width direction of the arc-shaped baffle 2 (i.e., the baffles are parallel to the width direction of the arc-shaped baffle 2) and are spaced apart along the length direction of the arc-shaped baffle 2. One end of the baffle 3 is connected to the inner groove surface of the arc-shaped baffle 2, and the other end extends slightly out of the inner groove of the arc-shaped baffle 2, pointing towards the hub of the drive wheel, maintaining a vertical distance from the rim of the drive wheel, and resisting part of the water flow impact within the flowable space formed between the baffle 3 and the rim of the drive wheel. The forward propulsion can also be controlled to a certain extent by adjusting the height of the baffle 3 (i.e., the height extending from the end connected to the arc-shaped baffle 2 towards the drive wheel) and the spacing.

[0028] Specifically, the arc-shaped baffle 2 covers one-third to one-half of the circumference of the upper rim of the drive wheel.

[0029] The arc-shaped baffle 2 is provided with horizontal thin plates 5 at both ends, which facilitates the flow of water into the flowable space formed between the inner groove of the arc-shaped baffle 2 and the wheel rim of the drive wheel.

[0030] The upper surface of the arc-shaped baffle 2 is movably connected to the fender of the amphibious vehicle, used to adjust the distance between the arc-shaped baffle 2 and the drive wheel, thereby changing the height of the flowable space formed between the inner groove of the arc-shaped baffle covering the wheel rim and the wheel rim. Specifically, the arc-shaped baffle 2 is movably connected to the fender via a telescopic assembly (not shown in the figure), and the connection point is located in the middle of the upper surface of the arc-shaped baffle 2. Figure 1 The part 1 is connected to the fender telescopic device. The telescopic assembly can be a spring telescopic assembly. When the spring extends or retracts, the arc-shaped baffle 2 moves vertically, thereby changing the vertical distance between the end of the vertical partition 3 in the groove of the arc-shaped baffle 2 and the wheel rim.

[0031] The arc-shaped baffle 2 is also provided with a circumferential length adjustment component 4, which is used to adjust the arc length of the arc-shaped baffle 2, thereby adjusting the circumferential coverage range of the arc-shaped baffle 2 on the drive wheel.

[0032] In some embodiments, the circumferential length adjustment component 4 is a telescopic plate structure. For example, an arc-shaped baffle is fitted inside another plate-like tube, and a limiting structure is provided, allowing the arc-shaped baffle to be pulled out and pushed in from the plate-like tube to adjust the arc length. Specifically, the telescopic plate is configured as a transmission telescopic structure, with the two arc-shaped baffles connected by a gear transmission device (not shown in the figure). When the gear rotates, the baffle extends circumferentially, thereby changing the circumferential coverage distance between the inner groove of the baffle and the rim. In some preferred embodiments, a foldable partition can also be provided on one of the arc-shaped baffles. When extended circumferentially, the folded partition can be opened, ensuring that the partitions are still evenly distributed.

[0033] When the drive wheel rotates, the water flow stirred by the wheel rim generates water flow in the flowable space formed between the inner groove of the arc-shaped baffle 2 and the upper wheel rim of the drive wheel. The water flow impacts the partition 3, generating resistance. The water flow force on the upper wheel rim of the drive wheel decreases, while the water flow force on the lower wheel rim of the drive wheel is greater than that on the upper wheel rim, thereby increasing the difference in water flow impact force. When the arc-shaped baffle 2 descends and extends circumferentially, the vertical distance between the end of the vertical partition 3 and the wheel rim decreases, and the circumferential distance covered by the arc-shaped baffle 2 on the wheel rim increases. This increases the resistance, the difference in water flow impact force, and the forward momentum.

[0034] Example 2

[0035] This invention provides an amphibious vehicle, including the booster attachment device described in Embodiment 1. Specifically, the amphibious vehicle includes a vehicle body and drive wheels, with an arc-shaped baffle 2 covering the drive wheels above them. A telescopic device connected to a fender is provided on the upper surface of the arc-shaped baffle 2, and transmission devices are provided on both sides of the arc-shaped baffle 2; a horizontal thin plate is provided at the end of the arc-shaped baffle 2.

[0036] The booster attachment is located on the lower surface of the fender of the amphibious vehicle. The two sides of the baffle are connected to each other through a transmission device, and the arc-shaped baffle 2 covers the wheel rim of the drive wheel. The outer contour of the baffle is arc-shaped and covers the wheel rim of the drive wheel. The arc-shaped booster attachment has multiple vertically arranged partitions in the grooves pointing towards the wheel hub. The partitions are evenly spaced and the ends of the partitions maintain a vertical distance from the drive wheel. The vertical distance can be changed by a telescopic device.

[0037] Example 3

[0038] This invention provides a propulsion method for amphibious vehicles to navigate on water. By covering the drive wheel with an arc-shaped baffle with a partition on its inner side, a flowable space is formed between the inner groove of the arc-shaped baffle and the upper rim of the drive wheel, thereby adjusting the impact force difference between the upper and lower rims of the drive wheel and improving the forward propulsion of the amphibious vehicle.

[0039] Furthermore, by adjusting the distance and arc length between the arc-shaped baffle 2 and the amphibious vehicle's drive wheel, the size of the flow space can be adjusted, thereby adjusting the difference in water flow impact force on the drive wheel, and ultimately adjusting the magnitude of the thrust.

[0040] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
