Description

Technical Field

[0001] The present invention belongs to the technical field of amphibious vehicles, and in particular relates to an amphibious vehicle. Background Art

[0002] Most existing amphibious vehicles are modified from various basic chassis, usually with only the bottom of the vehicle waterproofed and sealed, and the exterior generally adopts a ship-shaped body. Compared with general traditional vehicles, the front of the vehicle is located higher, similar to the bow of a ship. In addition, to ensure the suspension and vibration reduction performance, its rear axle, shock absorber, buffer structure and other components are inevitably exposed outside the vehicle body. In other words, when driving in water, due to the lack of ground reaction force, the wheels, rear axle and other components will sink further relative to the bottom of the vehicle, causing excessive water resistance. The water resistance of current amphibious vehicles is mainly caused by the body shape and external accessories. In addition, its system architecture adopts land and water system control units that usually operate independently, lacking unified intelligent management, resulting in unreasonable energy distribution or high operational complexity.

[0024] The following drawings illustrate various embodiments of the present invention. For clarity, many physical details will be included in the following description. However, it should be understood that these physical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these physical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0025] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] This embodiment provides an amphibious vehicle. The amphibious vehicle system adopts two front drive wheels 12 and one rear drive wheel 13, and the overall layout is triangular, so that it has higher stability when traveling on land. It also adopts two rear underwater thrusters 20, which drive the generator to generate electricity through the pedal part, and send the drive signal through the corresponding module to drive the two rear underwater thrusters 20. In addition, the modules of the amphibious vehicle system of this embodiment have a high degree of coordination and cooperation, and the switching between land mode and water mode is smooth.

[0027] Combine Figures 1 to 4As shown, the amphibious vehicle of this embodiment includes a chassis 10, an underwater propeller 20, a pedal portion 30, a seat 40 and a control unit 50. A body 11 is provided on the chassis 10, and a front drive wheel 12 and a rear drive wheel 13 are provided at the bottom of the chassis 10. The underwater propeller 20 is installed at the bottom of the chassis 10 to push the vehicle. The pedal portion 30 is provided at the front end of the body 11 for stepping operation. The seat 40 is installed on the body 11 and corresponds to the position of the pedal portion 30. A drive motor (a protective cover is used to protect the drive motor) and a generator are provided in the body 11. The drive motor is connected to the underwater propeller 20 to move the underwater propeller 20. 0 drive, the generator is connected to the pedal part 30 to generate electricity, the battery part is located at the end of the vehicle body 11, and corresponds to the position of the control part 50 (in this embodiment, the upper and lower corresponding relationship). During the normal water riding process of the vehicle, the foot must be continuously stepped on to achieve full power output. The fastest speed is 25km / h. When the foot stops operating, the vehicle will enter the energy recovery mode, and the generator will convert kinetic energy into electrical energy to charge the lithium battery. At this time, the vehicle will encounter certain resistance. During the water riding process of the vehicle, you must pay attention to braking. There is a certain braking distance and there will be a water sliding distance, so you need to consider squeezing the brake to the bottom in case of emergency braking.

[0028] In this embodiment, when the lithium battery is at more than 96% of the battery power, the pedal power generation function will be lost, that is, in this case the feet will be lighter and there will be no feeling of power generation. If the power is lower than 96%, there will be a power generation effect. When the water riding is completed, the gear position will first reach 0 and then turn off. The brake force button must be pressed to prevent the vehicle from sliding for a long time. When the operator's feet stop walking, the water vehicle will enter the energy recovery mode, and the battery will be charged in this process. This embodiment uses the corresponding modules to monitor the battery in real time, which can effectively protect the safety of the entire system. Through the real-time control of the GCU module, MCU module and VCU module, the MCU module can control the magnitude of the motor driving force through the frequency and speed of human pedaling.

[0029] Furthermore, in this embodiment, the number of front drive wheels 12 is two, the number of rear drive wheels 13 is one, and the overall layout forms a triangular layout (in actual use, the number of rear drive wheels 13 can be two, forming a quadrilateral layout). The triangular layout formed by the two front drive wheels 12 and the one rear drive wheel 13 can effectively improve the stability of the vehicle. The number of underwater thrusters 20 is two, and they are installed at the rear end of the chassis 10. An operating joystick 60 is provided on the vehicle body 11, and the operating joystick 60 corresponds to the position of the seat 40 for control operation. In addition, the amphibious vehicle adopts two rear underwater thrusters 20, which drive the generator through the pedal part to generate electricity, and sends the drive signal through the corresponding module to drive the two rear underwater thrusters 20.

[0030] like Figure 3 As shown, the control unit 50 of the amphibious vehicle of this embodiment is located at the end of the vehicle body 11. The control unit 50 includes a BCU module, a VCU module, a GCU module, an MCU module, an LCU module and an IOT module for control. The BCU module, VCU module, GCU module, MCU module, LCU module and IOT module of this embodiment can share a set of products to switch different modules to realize vehicle control. The modules of this embodiment are designed in a modular circuit for maintenance. Through independent instrument Bluetooth, controller Bluetooth and IOT modules, independent online multi-channel control data platform upload can be realized. The power of energy recovery of the entire system is controlled by the LCU module, which can effectively protect the safety of the entire system. Furthermore, the GCU module and MCU module are controlled in real time through the VCU module. The MCU module can be controlled by the frequency and speed of human pedaling, thereby controlling the driving force of the main motor.

[0031] In actual use, the amphibious vehicle of this embodiment employs an operator sitting in one, two, or more seats 40 and using their feet to drive (step on) one, two, or more pedals 30. The pedals 30 then generate electricity for one, two, or more generators. Furthermore, one, two, or more VCU modules perform logical analysis, which in turn transmits control signals to one, two, or more MCU modules, which in turn transmit drive signals to drive one, two, or more rear-mounted underwater thrusters 20, thereby operating in a surface mode. At the land-water or land-water interface, the remote control lever and pedals coordinate to drive the motor and underwater thruster, respectively, to achieve switching between land-water and land-water interfaces.

[0032] During the switching operation, the remote control lever and pedals respectively drive and generate electricity for one, two, or more drive motors and the generator. One, two, or more VCU modules perform logical analysis, subsequently sending control signals to one, two, or more MCU modules and one, two, or more GCU modules, which then issue drive signals to drive one, two, or more drive motors and the rear underwater propeller 20, thereby enabling operation on land or at the land-water interface. When on land, the operator controls the drive motors via the remote control lever, causing the front and rear drive wheels 12, 13 to drive on land. When on water, the operator controls the underwater propeller 20 via the pedals (which drive the motors and then send control signals via the GCU module), enabling the underwater propeller 20 to operate on water. Furthermore, this embodiment includes a buoyancy section beneath the vehicle chassis 10, enhancing the buoyancy of the amphibious vehicle. The amphibious vehicle system is waterproof and sealed in all parts that come into contact with water, and other areas that may come into contact with water are also waterproof and sealed, resulting in a large number of waterproof and sealed parts. Furthermore, the amphibious vehicle system has various peripheral components, such as, but not limited to, Bluetooth instruments, Bluetooth controllers, IoT modules, and LCU modules.
