Description

Technical Field

[0001] This invention relates to the field of electric boats, and in particular to a small electric boat for recreational land travel. Background Technology

[0002] Small boats travel on water. If boating is to be used as a recreational activity, it can only be done on water. Without waters that can accommodate small boats, this recreational activity cannot be carried out, and it cannot satisfy the desires of some people. Boating on water is more dangerous than recreational activities on land, especially for children. Currently, amusement parks only have various electric vehicles, and there is no electric small boat that can travel on land as a recreational activity. This electric small boat is similar in shape to the small boat on water, and the rowing method is also similar. It satisfies the desire to row on land, and importantly, it is safer than rowing on water. Summary of the Invention

[0003] The electric land-based boat, resembling a small boat in shape, is hereinafter referred to as "the boat." Its distinguishing feature is that it moves on land using two omnidirectional wheels and two drive wheels. The two omnidirectional wheels are unpowered, while the two drive wheels are powered. There are two control methods: rowing with oars and propelling with a pole, selectable via a switch. Rowing with oars involves the user mimicking rowing motions on water, controlling the boat without contacting the surface. Rowing controls the boat's movement (straight ahead, stop, left turn, right turn) and does not provide propulsion. The oars are a single component; the two oars are the first oar assembly and the second oar assembly. The oar assembly contains a generator, which is a gear-driven speed-increasing generator. This generator controls the boat's movement when rowing. The pole-steering mechanism involves the user using a matching pole to mimic the action of rowing in water. The pole's probe contacts the surface. Pole-steering controls the boat's movement (straight ahead, stopping, turning left, and turning right), but does not provide power for the boat's movement. The pole itself is an assembly containing a pressure sensor, which is a resistive pressure sensor. This pressure sensor controls the boat's movement when rowing. Further explanation follows with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0017] Referring to Figures 1, 2, and 3, the land-based electric boat uses hull 1 as its main body. Hull 1's shape is similar to that of a boat in water, consisting of a side 1-1 and a bottom 1-2. One end of hull 1 is the bow, and the other end is the stern. When moving, the bow is forward. Its purpose is to be used as a recreational device on land; it cannot be used in water. The user inside the boat mimics rowing or propelling motions to control the boat's movement (straight, stopping, turning left, and turning right). The boat moves on land using two casters and two drive wheels. The two casters are the casters in the first caster assembly 4 and the second caster assembly 14, and are non-powered. The two drive wheels are the drive wheels in the first drive wheel assembly 5 and the second drive wheel assembly 15, and are powered. The two casters and two drive wheels are mounted on the bottom 1-2. There are two ways for the user to control the boat. The first is to use two oars to imitate paddling in the water, and the second is to use a pole to imitate rowing in the water. The user can only choose one of the methods to control the boat. The two control methods are switched by a switch 7. Inside the boat, there is a foot brake 6, a switch 7, a decoding signal receiving circuit 8, and a power supply 13.

[0018] Referring to Figure 1, since two caster wheel assemblies and two drive wheel assemblies are installed on the bottom 1-2 of the boat, the appearance of the electric boat is affected. The purpose of the apron 2 is to cover the two caster wheel assemblies and two drive wheel assemblies, so that they cannot be seen from the outside. The apron 2 is made of soft material, and the outward side is marked with a pattern, which is based on water flow, waves, aquatic plants and animals. The apron 2 is generally located in the lower half of the side 1-1 of the boat. Special styles cover the entire side 1-1 of the boat and are wrapped around the whole side 1-1.

[0019] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, to describe the structure and working principle of the small boat in more detail, the left side of the boat when the user is facing the bow is set to the left side, and the right side to the right side is set to the right side. The first microwave radar 10 is set to the right side of the bow, and the second microwave radar 11 is set to the left side of the bow. The first universal wheel assembly 4 and the first drive wheel assembly 5 are set to the left side, and the second universal wheel assembly 14 and the second drive wheel assembly 15 are set to the right side. The first paddle connector 16 is set to the left side, and the second paddle connector 17 is set to the right side. The first paddle assembly 19 is set to the left side, and the second paddle assembly is set to the right side.

[0020] Referring to Figure 2, there are two microwave radars at the bow end of the boat (1-1): a first microwave radar 10 and a second microwave radar 11. The first and second microwave radars 10 and 11 have two functions. First, when using a pole-assisted propulsion system, they work together with the pole to control the boat's left and right turns, respectively. The first microwave radar 10 controls the motor in the drive wheel assembly on the left side of the boat, and the second microwave radar 11 controls the motor in the drive wheel assembly on the right side of the boat. Second, when an obstacle is encountered on the right side of the bow, the boat automatically steers to the left to avoid it; when an obstacle is encountered on the left side of the bow, the boat automatically steers to the right to avoid it. The sensing distance of the first and second microwave radars 10 and 11 is adjusted according to the requirements of different models. Too far a sensing distance can easily cause erroneous actions; too close a sensing distance will prevent the pole from controlling the electric boat's left and right turns. The third microwave radar 12 is located in the center of the stern. Its function is to work with the pole to control the boat's straight-line movement. The pole is positioned near the third microwave radar 12. Within the sensing range, the probe tip contacts the road surface and applies force, causing the small boat to move forward under control.

[0021] Referring to Figures 1 and 3, two caster wheel assemblies and two drive wheel assemblies are located at position 1-2 on the bottom of the boat. The two caster wheel assemblies are the first caster wheel assembly 4 and the second caster wheel assembly 14, and the two drive wheel assemblies are the first drive wheel assembly 5 and the second drive wheel assembly 15. Each caster wheel assembly consists of a bracket and casters. A shock-absorbing spring (first shock-absorbing spring 3) is located between the first caster wheel assembly 4 and the bottom of the boat (1-2), and its function is shock absorption. A shock-absorbing spring is also located between the second caster wheel assembly 14 and the bottom of the boat (1-2), serving the same purpose. The two drive wheel assemblies are the first drive wheel assembly 5 and the second drive wheel assembly 15. Both the first caster wheel assembly 4 and the second caster wheel assembly 14 are located at the bow end of the boat. Both should be at the stern, or both drive wheel assemblies should be at the bow, and both caster wheel assemblies should be at the stern. It is not possible for one caster wheel assembly to be at the bow and the other at the stern, or for one drive wheel assembly to be at the bow and the other at the stern.

[0022] Referring to Figures 4 and 6, the first paddle connector 16 and the second paddle connector 17 have the same structure. The first paddle connector 16 has a hole, 16-1, which serves to fix the connecting shaft on the first paddle assembly 19. The first paddle connector 16 has two rotating shafts at its ends: a first rotating shaft 16-2 and a second rotating shaft 16-3. These two rotating shafts are coaxial and are located in holes on the first side rail fixing member 1-1-1 and the second fixing member 1-1-2, respectively. The first side rail fixing member 1-1-1 and the second fixing member 1-1-2 are fixing members on the same side of the side rail. With the connecting shaft on the first paddle assembly 19 fixed in the first paddle connector hole 16-1, the paddle can rotate not only around its own connecting shaft but also around the first rotating shaft 16-2 and the second rotating shaft 16-3, more realistically mimicking the action of rowing in water. The second paddle connector 17... There is a hole on it, which is the second propeller connector hole 17-1. The connecting shaft on the second propeller assembly is fixed in the second propeller connector hole 17-1. Its principle and installation position are the same as those of the first propeller connector 16.

[0023] Referring to Figures 5 and 7, the first drive wheel assembly 5 and the second drive wheel assembly 15 utilize the first drive wheel damping spring 9 and the second drive wheel damping spring 18, respectively, to achieve damping. The mounting holes and output shaft holes on the outer shell of the first drive wheel assembly 5 are opposite to those on the outer shell of the second drive wheel assembly 14, and the internal parts are identical. In practical applications, the drive wheel assembly outer shell is universal, and its mounting holes and output shaft holes are common to both the first drive wheel assembly 5 and the second drive wheel assembly 15. The first drive wheel assembly 5 consists of a motor 5-3, a gearbox, and a drive wheel 5-2. Inside the gearbox outer shell 5-1 are a motor shaft gear 5-4, an electromagnetic brake coil 5-5, a brake wheel 5-6, an output shaft 5-7, and an output shaft gear 5-8. The principle is that when the motor 5-3 rotates, the motor shaft gear 5-4 meshes with the output shaft gear 5-8 to reduce speed, and then the output shaft 5-7 drives the drive wheel 5-2 to rotate. When connected to a power source, the iron core in the electromagnetic brake coil 5-5 is controlled to contact the brake wheel 5-6, thus achieving the purpose of braking.

[0024] Referring to Figure 8, the first paddle assembly 19 is similar in shape to a rowing paddle and consists of a paddle blade 19-1, a generator 19-2, a drive gear 19-3, a ratchet 19-4, a pawl 19-5, a paddle encoding signal transmission circuit module 19-6, a paddle power supply 19-7, a paddle handle 19-8, a paddle housing 19-9, a connecting shaft 19-10, and a paddle power switch 19-11. The generator 19-2 is a gear-driven generator. The drive gear 19-3 engages with the driven gear in the engagement device to rotate, driving the generator to produce electricity. The paddle encoding signal transmission circuit module 19-6 consists of a square wave signal generation circuit and an encoding signal transmission circuit. The axis of the connecting shaft 19-10 is perpendicular to the longitudinal axis of the paddle housing 19-9. The function of the connecting shaft 19-10 is to insert its protruding end portion 19-10-1 into the first paddle connector hole 16-1 on the first paddle connector 16. Inside, screws or connectors are used to fix it in this hole. The end portion 19-10-1 of the connecting shaft 19-10 has a stepped structure between it and the shaft body, which serves to better connect with the first paddle connector 16. After connection, the first paddle assembly 19 rotates around the connecting shaft 19-10, and the ratchet 19-4 rotates around the connecting shaft 19-10. The ratchet teeth of the ratchet 19-4 mesh with the pawl 19-5. The pawl shaft of the pawl 19-5 is fixed to the connecting shaft 19-10, and the pawl 19-5 rotates around the pawl shaft. There is also a pawl spring on the pawl shaft. The function of this structure is to use the action of the pawl 19-5 to control the ratchet 19-4 to rotate only in one direction on the connecting shaft 19-10, rotating in the direction of the pawl 19-5, but unable to rotate against the direction of the pawl 19-5. The spur gear meshes with the drive gear 19-3 in the power generation device.

[0025] The two propeller assemblies are a first propeller assembly 19 and a second propeller assembly. The first propeller assembly 19 controls a drive wheel assembly, designated as the first drive wheel assembly 5, and controlling the drive wheel assembly means controlling the motor within it. The second propeller assembly controls a drive wheel assembly, designated as the second drive wheel assembly 15, and controlling the drive wheel assembly means controlling the motor within it. The two propeller assemblies do not interfere with each other. The second propeller assembly consists of propeller blades, a generator, a drive gear, a ratchet, a pawl, a propeller encoding signal transmission circuit module, a propeller power supply, a propeller handle, a propeller housing, a connecting shaft, and a propeller power switch. The first propeller assembly 19 and the second propeller assembly have the same appearance and internal parts, the only difference being that the direction of the connecting shaft is opposite. It is designed that when the user pushes the two propeller handles towards the bow, the generator in the propeller assembly generates electricity; when the user pulls the two propeller handles towards the stern, the generator in the propeller assembly does not generate electricity.

[0026] Referring to Figure 8, the control component of the first paddle assembly 19 that controls the first drive wheel assembly 5 is the generator 19-2 within it. The generator 19-2 controls the paddle encoding signal transmitting circuit module 19-6 to transmit control signals, which are finally controlled by the decoding signal receiving circuit 8 on the hull. The circuit principle is as follows: When the user manipulates the paddle handle to simulate rowing in the water, the paddle handle 19-8 is pushed towards the bow, causing the first paddle assembly 19 to rotate around the connecting shaft 19-10. The ratchet 19-4, controlled by the pawl 19-5, cannot rotate around the connecting shaft 19-10. Since the ratchet 15-4 does not rotate, only the drive gear 19-3 rotates, thereby driving the generator 19-2 to generate electricity. When the paddle handle 19-8 is pulled towards the stern, the first paddle assembly 19 rotates around the connecting shaft 19-10, and the pawl 19-5 cannot control the ratchet 19-4. The ratchet 19-4, connected to the connecting shaft 19-10, rotates. Since the ratchet 19-4 rotates, the drive gear 19-3 cannot rotate, the generator 19-2 cannot generate electricity, and therefore cannot control the paddle encoder signal transmitting circuit module 19-6 to transmit remote control signals. The principle of the second paddle assembly controlling the second drive wheel assembly 15 is the same as the principle of the first paddle assembly 19 controlling the first drive wheel assembly 5.

[0027] Referring to Figure 8, the generator 19-2 is used as a component to control the movement of the small boat. Compared with the existing pedal acceleration device and handle acceleration device of vehicles, the pedal acceleration device and handle acceleration device can be fixed at a certain position within the range of motion, so the control signal can be output continuously. When rowing with a paddle, the boat is constantly performing rowing actions within the range of motion, so the control signal can be uninterrupted, and the small boat can keep moving, which conforms to the rowing action habits.

[0028] Referring to Figure 9, the strut assembly 20 consists of a probe 20-1, a pressure sensor 20-2, a strut housing 20-3, a strut encoding signal transmission circuit module 20-4, a strut power supply 20-5, and a strut power switch 20-6. The strut encoding signal transmission circuit module 20-4 consists of a square wave signal generation circuit and an encoding signal transmission circuit. One end of the probe 20-1 is inside the strut housing 20-3 and in contact with the pressure sensor 20-2, while the other end is outside the strut housing 20-3.

[0029] Referring to Figure 9, the working principle of the strut assembly 20 is as follows: When using the strut to propel the boat, the probe 20-1 is in contact with the road surface at one end outside the strut housing 20-3. The user controls the strut to exert force on the road surface, and this force is converted into a control force for the pressure sensor 20-2 through the probe 20-1. The greater the force exerted by the strut on the road surface, the greater the control force of the pressure sensor 20-2, and vice versa. The force applied to the pressure sensor 20-2 is controlled by changing the resistance value across the pressure sensor 20-2, thereby controlling the pulse width duty cycle of the square wave signal generating circuit. The pressure sensor 20-2 first controls the signal generating circuit to emit a square wave signal with a changing pulse width duty cycle, and then the square wave signal controls the encoded signal transmitting circuit module 20-4 to transmit a control signal. Finally, the decoding signal receiving circuit 8 on the hull controls the first drive wheel assembly 5 and the second drive wheel assembly 15. Controlling the drive wheel assembly means controlling the motor within it.

[0030] Referring to Figure 10, this circuit is a general circuit for both the paddle assembly and the strut assembly. Circuit component descriptions: The first paddle assembly 19 contains a generator G, a first resistor R1, and an optocoupler OC, but no pressure sensor IC1. The strut assembly 20 contains a pressure sensor IC1, but no generator G, first resistor R1, or optocoupler OC. An adjustable resistor RT, a second resistor R2, a first capacitor C1, a second capacitor C2, and a 555 timer IC2 form a square wave signal generation circuit. The first power supply DC1 is the power source. The first switch K1 is the power switch. IC3 refers to the encoded signal transmission circuit module; its function is to transmit encoded signals. The first voltage regulator module IC4 uses a 5V voltage regulator in the circuit.

[0031] Referring to Figure 10, the circuit principle is as follows: If this circuit is used in the paddle assembly, the paddle speed changes the voltage at the output terminal of the generator 19-2. The faster the paddle speed, the higher the voltage at the output terminal of the generator 19-2, and the lower the resistance at the output terminal of the optocoupler OC. As a result, the pulse width duty cycle output by the square wave signal generator circuit is larger, thereby controlling the motor speed and the corresponding speed of the electric boat. If this circuit is used in the strut assembly 20, the magnitude of the force between the probe 20-1 in the strut assembly and the road surface changes the resistance across the pressure sensor 20-2. The greater the control force of the pressure sensor 20-2, the larger the pulse width duty cycle output by the square wave signal generator circuit, thereby controlling the motor speed. The higher the speed, the faster the boat travels.

[0032] Referring to Figure 11, this circuit is the decoding signal receiving circuit 8 on the ship's hull. Circuit component descriptions: The address code of the first decoding signal receiving circuit module IC7 is the same as the address code of the third decoding signal receiving circuit module IC9, enabling it to simultaneously receive the encoded signal transmitted by the encoded signal transmitting circuit module IC3 with the same address code. The address code of the second decoding signal receiving circuit module IC8 is different from the address codes of IC7 and IC9. The second voltage regulator module IC5 and the third voltage regulator module IC6 use 5V voltage regulator modules in the circuit. The first motor M1 refers to motor 5-3 in the first drive wheel assembly 5, and the second motor M2 refers to the motor in the second drive wheel assembly 15. The first diode D1 and the second diode D2 are both freewheeling diodes. IC10 refers to the first microwave radar 10, IC11 refers to the second microwave radar 11, and IC12 refers to the third microwave radar 12. The first relay J1 is controlled by the first microwave radar IC10, the second relay J2 is controlled by the second microwave radar IC11, and the third relay J3 is controlled by the third microwave radar IC12. The control of the first transistor VT1 and the second transistor VT2 is to control the first motor M1 and the second motor M2, respectively. In practical applications, due to the limitation of output power, a single transistor VT1 and the second transistor VT2 cannot drive the motor. Multiple high-power transistors must be connected in parallel to drive the motor. The third capacitor C3, the third resistor R3 and the first transistor VT1 form a delay circuit. The fourth capacitor C4, the fourth resistor R4 and the second transistor VT2 form a delay circuit. The second switch K2 is the power switch. The second power supply DC2 refers to the hull power supply 13. The third switch K3 refers to the switch controlled by the foot brake 6. The fourth switch K4 refers to the changeover switch 7. The first electromagnetic brake coil YA1 refers to the electromagnetic brake coil in the first drive wheel assembly 5. The second electromagnetic brake coil YA2 refers to the electromagnetic brake coil in the second drive wheel assembly 15.

[0033] Referring to Figure 11, the switching principle between double-oar rowing and pole-pole rowing in the circuit is as follows: For double-oar rowing, the fourth switch K4 is connected to the output of IC8; for pole-pole rowing, the fourth switch K4 is connected to the output of IC7. The address code of IC8 is set to be the same as the address code of the oar encoding signal transmitting circuit module 19-6 in the first oar assembly 19. Its function is to only receive the encoding signal emitted by the first oar assembly 19 and not the encoding signal emitted by the second oar assembly. The address code of IC9 is set to be the same as the address code of the oar encoding signal transmitting circuit module 20-4 in the second oar assembly. This ensures that it only receives the encoding signal emitted by the second oar assembly and not the encoding signal emitted by the first oar assembly 19. Only then can the first oar assembly 19 and the second oar assembly control their respective drive wheel assemblies without interference. For pole-pole rowing, the address codes of IC7 and IC9 are set to be the same as the address codes of the pole encoding signal transmitting circuit module 20-4. The emitted coded signals can be received by IC7 and IC9, so that the strut assembly 20 can simultaneously control the first drive wheel assembly 5 and the second drive wheel assembly 15.

[0034] Referring to Figure 11, the circuit principle is as follows: After receiving the encoded signal, IC8 decodes it internally and outputs a control signal. The duration of this control signal depends on the duration of a single stroke of the oar or the duration of force applied after the pole touches the ground. This control signal passes through a delay circuit composed of the third resistor R3 and the third capacitor C3, controlling the first transistor VT1. The first transistor VT1 then controls the first motor M1 to rotate. The purpose of this circuit is to ensure that the boat continues to travel a certain distance after the user strokes the oar, preventing the boat from stopping immediately after paving. The circuit principles of IC9, the fourth resistor R4, the fourth capacitor C4, the second transistor VT2, and the second motor M2 are the same as described above. When the first microwave radar IC10 is within its sensing range and detects a moving object, it outputs a control signal to turn on the first relay J1, causing its contact J1-1 to open. This disconnects the control signal from the first transistor VT1, stopping the first motor M1 from rotating. The pole, placed within the sensing range of the microwave radar, is essentially a moving object. The second microwave radar IC11... The circuit principle is the same as that of the first microwave radar IC10. In the circuit, J1-1 and J2-1 are normally closed contacts, and J3-1 and J3-2 are normally open contacts. IC12 controls J3 to close, and after closing, J3-1 and J3-2 close.

[0035] The method of using a double oar rowing boat is as follows: The user imitates the action of rowing in water, gripping the oar handles with both hands and pushing forward and pulling back. If both oars are used simultaneously with equal force, the boat will move straight. If the user's left hand controls the oar to row continuously while the right hand stops rowing or slows down, the boat will turn right. The greater the force of the left hand's oar, the smaller the turning radius when turning right, and vice versa. If the boat turns left, the principle is the same as turning right. During the process of pushing the oar handle forward and the subsequent delay, the boat is moving, and the speed gradually decreases. If the boat needs to move continuously, the rowing action must be continuous. If it is necessary to stop moving midway, in addition to stopping the rowing action, in special cases such as downhill roads, the foot brake can be used.

[0036] The method of using a pole to propel a boat is as follows: The user imitates the action of paddling in water. Within the sensing range of the third microwave radar IC12 at the stern of the boat, the probe end of the pole is brought into contact with the ground and appropriate force is applied. The greater the force applied to the pole, the faster the boat travels. This is for straight-line movement. To turn left, simply place the pole within the sensing range of the first microwave radar 10 and perform the paddling action. Because the pole is within the sensing range of the first microwave radar 10, the motor in the first drive wheel assembly 5 on the left side of the boat stops rotating, and only the motor in the second drive wheel assembly 15 on the right side of the boat rotates, thus turning the boat to the left. The greater the force applied to the pole, the smaller the turning radius. To turn right, simply place the pole within the sensing range of the second microwave radar 11 and perform the paddling action. Because the pole is within the sensing range of the second microwave radar 11, the motor in the second drive wheel assembly 15 on the right side of the boat stops rotating, and only the motor in the first drive wheel assembly 15 on the left side of the boat rotates. The motor in the boat rotates, causing the boat to turn right. The greater the control force of the pole, the smaller the turning radius. During a single pole-steering process and the subsequent delay, the boat is in motion, and its speed gradually decreases. If the boat needs to keep moving, the pole-steering action must be performed continuously. If it is necessary to stop moving midway, in addition to stopping the pole-steering action, in special cases such as downhill roads, the foot brake can be used.

[0037] In actual manufacturing, both the first drive wheel assembly 5 and the second drive wheel assembly 15 use a combination of DC motor, gearbox and drive wheel, and the control circuit is simple. If a hub motor is used instead, the control circuit must use the hub motor control circuit. There is no reversing function circuit in the circuit, and reversing can only be solved manually. If the actual application requires a reversing function, a motor forward and reverse rotation control circuit is added to the circuit.

[0038] In the actual manufacturing of this invention, in order to prevent the oar from exceeding the set range and causing accidents when rowing, two limiting parts are set on the left and right sides of the boat respectively. One limiting part restricts the range of the oar pushing forward, and the other limiting part restricts the range of the oar pulling backward.

[0039] In actual production, the finished products of this invention are divided into children's and adult types. The children's type is designed according to children's characteristics, and the shape, color, and pattern of the boat must meet children's preferences. In the same batch of products, the address codes of the coded transmission circuit modules in all paddle components, the address codes of the coded transmission circuit modules in all strut components, and the address codes of the decoding circuit modules in all hull circuits are all unique. Each boat is equipped with two paddles and one strut. Special models of boats are equipped with two struts. The purpose of this is to allow two users to use the struts to propel the boat, one in front to turn left and right, and the other in the back to drive, in order to increase the entertainment effect. The special models of boats have two drive wheel components made waterproof. The purpose of this is to allow the boat to be used in a shallow water area. It is not required to provide buoyancy, but only to provide support. The driving power still relies on the two drive wheels.

[0040] This invention is an electric recreational device suitable for use in amusement parks, parks, entertainment venues, etc. It can only travel within a limited area and cannot travel on roads with motor vehicles. The maximum speed set at the factory cannot exceed the speed limit stipulated by the road. Compared with existing recreational electric vehicles, especially children's rowing, it not only exercises the body but also cultivates physical coordination and other advantages.

A land-based electric boat, whose shape resembles that of a small boat on water, is characterized by: On land, it is driven by two omnidirectional wheels and two drive wheels on the bottom of the boat. The two omnidirectional wheels are non-powered wheels, and the two drive wheels are powered wheels. There are two ways to control its movement: the first is rowing with oars, and the second is rowing with poles. Use the switch (7) to switch and select the control method. Oar rowing refers to the use of two oars on a boat to control the small boat by mimicking the action of rowing in water. The oars do not contact the ground. Rowing is used to control the small boat to go straight, stop, turn left and turn right, but does not provide power for the small boat to move. The oar is a component. The two oars are the first oar assembly (19) and the second oar assembly. Each oar assembly has a power generation device. The power generation device is the component in the oar assembly that controls the movement of the small boat when the small boat is rowed by oars. Pole-assisted boating refers to the user using a matching pole to control a small boat by mimicking the action of rowing a boat in water. The protruding end of the pole is in contact with the ground. Pole-assisted boating is used to control the small boat to go straight, stop, turn left and turn right, but does not provide power for the small boat to move. The strut is a component, and the strut assembly (20) contains a pressure sensor (20-2). The pressure sensor (20-2) is a component in the strut assembly (20) that controls the movement of the small boat when the boat is propelled by the strut method.

2. The land-based electric boat according to claim 1, characterized in that: The two casters are casters in the first caster assembly (4) and the second caster assembly (14), and the two drive wheels are drive wheels in the first drive wheel assembly (5) and the second drive wheel assembly (15). The drive wheel assembly consists of a motor, a gearbox and drive wheels.

3. The land-based electric boat according to claims 1 and 2, characterized in that: The first propeller assembly (19) controls a drive wheel assembly independently. Controlling the drive wheel assembly means controlling the motor within it. The first drive wheel assembly (5) is set to control. The second propeller assembly controls a drive wheel assembly independently. Controlling the drive wheel assembly means controlling the motor within it. The second drive wheel assembly (15) is set to control. The two propeller assemblies do not interfere with each other.

4. The land-based electric boat according to claims 1 and 2, characterized in that: The strut assembly (20) consists of a probe (20-1), a pressure sensor (20-2), a strut housing (20-3), a strut encoding signal transmitting circuit module (20-4), a strut power supply (20-5), and a strut power switch (20-6). The pressure sensor (20-2) is a resistive pressure sensor. The pressure sensor (20-2) first controls the signal generating circuit to emit a square wave signal, and then the square wave signal controls the encoding signal transmitting circuit (20-4) to emit a control signal. Finally, the decoding signal receiving circuit (8) on the hull controls the first drive wheel assembly (5) and the second drive wheel assembly (15). Controlling the drive wheel assembly means controlling the motor in it.

5. The land-based electric boat according to claims 1 and 3, characterized in that: The first propeller assembly (19) consists of a propeller blade (19-1), a power generator (19-2), a drive gear (19-3), a ratchet (19-4), a pawl (19-5), a propeller encoding signal transmitting circuit module (19-6), a propeller power supply (19-7), a propeller handle (19-8), a propeller housing (19-9), a connecting shaft (19-10), and a propeller power switch (19-11). The power generator (19-2) is a gear-speed-increasing power generator. The power generator (19-2) first controls the signal generating circuit to emit a square wave signal, and then the square wave signal controls the encoding signal transmitting circuit (19-6) to emit a control signal. Finally, the decoding signal receiving circuit (8) on the hull controls the first drive wheel assembly (5).

6. The land-based electric boat according to claims 1 and 3, characterized in that: The second propeller assembly consists of propeller blades, a generator, a drive gear, a ratchet, a pawl, a propeller encoding signal transmission circuit module, a propeller handle, a propeller housing, a connecting shaft, and a propeller power switch.
