Description

Technical Field

[0001] This invention relates to the field of toys, and in particular to an amphibious toy armored vehicle. Background Technology

[0002] In the toy model industry, amphibious toy armored vehicles have become popular products due to their ability to move on both land and water, offering diverse user experiences. However, most similar toy products on the market currently employ simplified structural designs, with their core flaws stemming from the conflicting structural requirements of "water buoyancy assurance" and "land mobility." This results in both aspects having relatively low performance levels, making it difficult to meet user needs.

[0003] Existing amphibious toy armored vehicles need to balance the requirements of being unsinkable on water and maneuverable on land, but these two requirements have fundamentally contradictory structural needs: to ensure unsinkability on water, existing products generally use lightweight materials. However, using lightweight materials results in insufficient overall weight of the vehicle, leading to problems such as poor track traction, difficulty in accurately controlling the trajectory, and weak obstacle-crossing ability when driving on land. Furthermore, even if such products can barely float in static water, once they begin to move, due to their excessively light weight and insufficient buoyancy reserves, they are prone to tilting, bumping, and even capsizing when faced with water currents or slight surface ripples, resulting in severely inadequate stability on water. Adding a small amount of weight to improve land performance, on the other hand, leads to insufficient buoyancy on water, increasing the risk of sinking once driving begins. This creates a core contradiction between weight and buoyancy, ultimately significantly limiting both the armored vehicle's land mobility and water stability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an amphibious toy armored vehicle that can take into account both land mobility and water stability, and can maintain a stable buoyancy whether it is entering the water or driving in the water.

[0005] To solve the above technical problems, the following technical solution is adopted:

[0006] An amphibious toy armored vehicle includes an armored vehicle body and a remote control. The armored vehicle body includes a chassis, a battery, a control device, a drive mechanism, two track mechanisms, and two spray pumps. The battery, control device, and drive mechanism are respectively mounted on the chassis. The control device, drive mechanism, track mechanisms, and spray pumps are electrically connected to the output terminals of the battery. The power output terminals of the drive mechanism are drively connected to the power input terminals of the two track mechanisms. The signal output terminal of the remote control is communicatively connected to the signal input terminal of the control device. The signal input terminals of the drive mechanism and spray pumps are electrically connected to the corresponding signal output terminals of the control device. The vehicle body includes a base. The upper housing and the base have an inner cavity. The upper housing is installed on the base and covers the opening of the inner cavity. The two track mechanisms are respectively installed on the left and right sides of the base. The two sides of the base are respectively provided with strip-shaped hollow floats extending to both sides. The strip-shaped hollow floats at least cover the upper area of ​​the track mechanism and form track baffles. There is a gap between the strip-shaped hollow floats and the track mechanism. A through hole is opened at the rear of the strip-shaped hollow floats. The two spray pumps are respectively installed on the rear of the upper surface of the two strip-shaped hollow floats. The spray pumps are provided with water inlet pipes at the rear. The water inlet pipes extend through the through hole into the gap. The water inlet of the water inlet pipes faces forward. The spray nozzle of the spray pump is opened at the rear end.

[0007] In the aforementioned amphibious toy armored vehicle, the remote control can control the armored vehicle to move on the ground and in the water. When moving on the ground, the drive mechanism can drive the track mechanism to complete actions such as moving forward, backward, turning left, turning right, or turning around on the spot. When moving in the water, the amount of water sprayed by the two spray pumps can be used to achieve forward movement and turning. Once the armored vehicle is launched into the water, the strip-shaped hollow floats act as buoys on both sides of the vehicle, providing buoyancy. Even if the armored vehicle is heavy, with the assistance of the strip-shaped hollow floats, it can still sink to the level of the spray pump, while the area above the spray pump remains above the water surface. In addition, when the spray pumps drive the armored vehicle to move, the pumps draw water from the water through the inlet pipe, which increases the water flow speed at the gaps, while the water flow speed below the track mechanism remains basically unchanged. This creates a pressure difference where the pressure is low at the gaps and high below the track mechanism. This pressure difference provides additional buoyancy to the strip-shaped hollow floats, ensuring that the armored vehicle can maintain a stable posture and not sink when moving rapidly in the water. This amphibious toy armored vehicle combines land mobility with water stability, eliminating the need for excessive weight reduction and ensuring maneuverability on land. Once submerged, it utilizes hollow, strip-shaped floats for buoyancy. Furthermore, the additional buoyancy generated by the water pump enhances its resistance to sinking at high speeds, improving stability. The hollow floats also function as track guards, preserving the vehicle's overall appearance.

[0008] The aforementioned spray pump is a miniature axial flow spray pump. The aforementioned strip-shaped hollow float can be made of lightweight materials, such as plastic or aluminum alloy.

[0009] In a preferred embodiment, the remote controller has a forward / reverse joystick, a left / right turn joystick, and a switch button for switching the control device between land mode and wading mode. In land mode, the remote controller controls the walking speed of the two tracked mechanisms on land, enabling the armored vehicle to move forward, backward, or turn. In wading mode, when the forward / reverse joystick and the left / right turn joystick are both moved by less than or equal to 50%, the control device controls the propulsion speed of the two spray pumps in the water, enabling the armored vehicle to move forward, backward, or turn in the water. The vehicle can move forward, backward, or turn at small angles. When in wading mode and the left and right steering levers are moved by more than 50%, the control device simultaneously controls the propulsion speed of the two spray pumps in the water and the water-dipping speed of the two track mechanisms, so that the armored vehicle can turn at large angles on the water surface. When in wading mode and the forward and backward steering levers are moved by more than 50%, the control device simultaneously controls the propulsion speed of the two spray pumps in the water and the water-dipping speed of the two track mechanisms, so that the armored vehicle can move forward, backward, land, and enter the water quickly.

[0010] The armored vehicle can freely switch between land and wading modes via a remote control, adapting to different driving scenarios. In land mode, by adjusting the travel speed and rotational speed difference of the two track mechanisms, the armored vehicle can move forward, backward, turn left, turn right, or make a U-turn on land, offering flexible control. In wading mode, tiered control is achieved based on the joystick movement: when the forward / reverse and left / right turn joystick movements are both less than or equal to 50%, only the spray pumps drive the vehicle, enabling smooth travel and small-angle turns. When the left / right turn joystick movement exceeds 50%, the control device controls the track mechanisms to simultaneously participate in water propulsion, significantly improving propulsion efficiency and steering torque. By separately controlling the propulsion difference of the two spray pumps and the water propulsion difference of the two track mechanisms, the armored vehicle can make large-angle turns on the water surface. When the forward / reverse joystick movement exceeds 50%, the control device simultaneously controls the propulsion speed of the two spray pumps and the water propulsion speed of the two track mechanisms. This system enables armored vehicles to move rapidly forward, backward, land, and launch into water. In transition zones between water and land, no additional operation is required; the tracks can directly drive the vehicle upon contact with land, while the spray pumps continuously provide auxiliary power in the water. This allows for a smooth and seamless transition between the armored vehicle and land, requiring no manual intervention. By employing this control logic, mode switching is linked to joystick amplitude, precisely adapting to both water and land scenarios. This effectively solves the problems of performance imbalance between water and land and cumbersome mode switching for armored vehicles, while also overcoming the pain point of requiring manual intervention in transition zones. It achieves easy driving and smooth automatic transitions, significantly improving the user experience and product practicality.

[0011] In a further preferred embodiment, the control device includes a joystick signal receiving module, a mode switching control module, and a speed adjustment module. The signal output terminals of the joystick signal receiving module and the mode switching control module are electrically connected to the corresponding signal input terminals of the speed adjustment module. The joystick signal receiving module is used to receive signals from the forward / backward joystick and the left / right turn joystick on the remote control. The speed adjustment module is used to receive signals from the switch button on the remote control. The speed adjustment module is used to control the forward, backward, turn, or mode switching of the armored vehicle body according to the signals issued by the joystick signal receiving module and the mode switching control module. When the user moves the forward / backward joystick on the remote control, the joystick signal receiving module captures the joystick's movement amplitude (e.g., 0%~100%) in real time and converts the amplitude signal into an electrical signal, which is then transmitted to the speed regulation module. The speed regulation module generates a corresponding PWM speed control signal based on the amplitude value (duty cycle increases with amplitude), causing the track mechanism and / or the spray pump to operate at the corresponding speed. The mode switching control module receives the signal from the switching key, thereby controlling the speed regulation module to switch between land mode (controlling only the drive mechanism) and wading mode (controlling both the spray pump and the drive mechanism simultaneously). The control device can use a microcontroller or microprocessor; the joystick signal receiving module, mode switching control module, and speed regulation module all use general-purpose remote control receiving modules.

[0012] In a further preferred embodiment, when the speed regulation module receives a switch from land mode to wading mode, the speed regulation module controls the spray pump to pre-start at 20% of its rated power for 2-4 seconds and controls the track mechanism to move forward at full power for 2-4 seconds. Then, after 2-4 seconds, the speed regulation module responds to the electrical signal sent by the joystick signal receiving module. When the speed regulation module receives a switch from wading mode to land mode, the speed regulation module simultaneously controls the spray pump and the track mechanism to move forward at full power for 2-4 seconds. Then, after 2-4 seconds, the speed regulation module responds to the electrical signal sent by the joystick signal receiving module. By adopting this logic, when switching to wading mode, the control device will not directly start the spray pump at full power, but will first pre-start it at 20% low power to avoid the armored vehicle body shaking or even overturning due to a sudden large flow impact. The track mechanism can still work for a certain period of time to provide time for transition from land to water. When switching to land mode, the control device can simultaneously control the spray pump and track mechanism to propel the armored vehicle body from the water to land with full power, so as to prevent it from running aground.

[0013] In a further preferred embodiment, the track mechanism includes a drive track, a drive wheel, and multiple driven wheels. The drive wheel is connected to the power output end of the drive mechanism, and each driven wheel is rotatably mounted on the base. The drive track is tensioned between the drive wheel and each driven wheel. The drive track includes multiple track sections connected in sequence, with a deflector plate in the middle of each track section. The deflector plate gradually slopes downwards from front to back. The front, back, and downward directions of the deflector plate are determined based on the position of the track section when it is in the forward section of the drive track. By setting the deflector plate, in land mode, the deflector plate can crawl, increasing friction, especially when traveling on muddy roads, it can also insert into the mud, further improving grip. In water-crossing mode, as the drive track rotates, the deflector plates in the forward section can also push the water backwards, further increasing the water-pushing force, improving propulsion efficiency and steering ability.

[0014] In a preferred embodiment, the upper surface of the upper housing is provided with a mounting groove, and a cover plate is provided on the mounting groove to cover the mounting groove. The control device is installed in the mounting groove. Since the upper surface of the upper housing is above the water surface after the armored vehicle enters the water, integrating the control device into the mounting groove of the upper housing, rather than in the cavity of the base, avoids the risk of water leakage caused by water flow, reduces the probability of water directly contacting the control device, further improves the waterproof reliability of the control device, and extends the service life of electronic components. Typically, the cover plate can be made in the shape of the armored vehicle's hatch cover.

[0015] In a preferred embodiment, the drive mechanism includes two planetary geared motors, each mounted within the inner cavity. Each planetary geared motor corresponds one-to-one with one of the two track mechanisms, and the power output of the planetary geared motor is connected to the power input of the corresponding track mechanism. The planetary geared motors are compact, and the torque after reduction and torque amplification is sufficient to drive the tracks against ground friction, thus meeting the drive requirements of the armored vehicle toy.

[0016] The beneficial effects of this invention are: this amphibious toy armored vehicle is suitable for both land and water scenarios, has precise control, and can easily switch between land and water driving, effectively improving the user experience. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figure 1-5 As shown, an amphibious toy armored vehicle includes an armored vehicle body and a remote control. The armored vehicle body includes a vehicle body 1, a battery (not shown), a control device (not shown), a drive mechanism 2, two track mechanisms 3, and two spray pumps 4. The battery, control device, and drive mechanism 2 are respectively mounted on the vehicle body 1. The control device, drive mechanism 2, track mechanisms 3, and spray pumps 4 are electrically connected to the output terminals of the battery. The power output terminals of the drive mechanism 2 are respectively connected to the power input terminals of the two track mechanisms 3. The signal output terminal of the remote control is communicatively connected to the signal input terminal of the control device. The signal input terminals of the drive mechanism 2 and spray pumps 4 are respectively electrically connected to the corresponding signal output terminals of the control device. The vehicle body 1 includes a base 101 and an upper shell 102. The base 101 has an inner cavity 101. 1. The upper housing 102 is mounted on the base 101 and covers the opening of the inner cavity 1011; two track mechanisms 3 are respectively mounted on the left and right sides of the base 101, and each side of the base 101 is provided with a strip-shaped hollow float 1012 extending to both sides. The strip-shaped hollow float 1012 covers the upper area of ​​the track mechanism 3 and forms a track baffle. There is a gap 5 between the strip-shaped hollow float 1012 and the track mechanism 3. A through hole 10121 is opened at the rear of the strip-shaped hollow float 1012; two spray pumps 4 are respectively mounted on the rear of the upper surface of the two strip-shaped hollow floats 1012. A water inlet pipe 401 is provided at the rear of the spray pump 4. The water inlet pipe 401 extends through the through hole 10121 into the gap 5. The water inlet of the water inlet pipe 401 faces forward, and the nozzle of the spray pump 4 is opened at the rear end.

[0024] In the aforementioned amphibious toy armored vehicle, the remote control can control the armored vehicle to move on the ground and in the water. When moving on the ground, the drive mechanism 2 can drive the track mechanism 3 to complete actions such as moving forward, backward, turning left, turning right, or turning around on the spot. When moving in the water, the amount of water sprayed by the two spray pumps 4 can be used to achieve forward movement and turning. After the armored vehicle is launched into the water, the strip-shaped hollow float 1012 can act as floats on both sides of the armored vehicle, providing buoyancy. Even if the armored vehicle is heavy, with the assistance of the strip-shaped hollow float 1012, the armored vehicle can still sink to a position level with the spray pump 4, while the area above the spray pump 4 can remain above the water surface. In addition, when the spray pump 4 sprays water to drive the armored vehicle body to move, the spray pump 4 draws water from the water through the water inlet pipe 401, which will accelerate the water flow speed at the gap 5, while the water flow speed below the track mechanism 3 remains basically unchanged. This creates a pressure difference with low pressure at the gap 5 and high pressure below the track mechanism 3. This pressure difference can provide additional buoyancy to the strip-shaped hollow float 1012, thereby ensuring that the armored vehicle body can maintain a stable posture and not sink when moving quickly in the water. This amphibious toy armored vehicle can balance land mobility and water stability without excessively pursuing lightweight design, ensuring its mobility on land. When launched into water, it can be buoyed by the strip-shaped hollow floats 1012. When moving in water, the additional buoyancy generated by the water pump 4 can enhance the armored vehicle's anti-sinking ability and improve its stability at high speeds in water. At the same time, the strip-shaped hollow floats 1012 can also form track baffles without affecting the overall appearance of the armored vehicle.

[0025] The aforementioned spray pump 4 is a miniature axial flow spray pump 4. The aforementioned strip-shaped hollow float 1012 can be made of thin and light materials, such as plastic or aluminum alloy.

[0026] The remote control has forward / reverse joysticks, left / right turn joysticks, and a switch button for switching between land and wading modes. In land mode, the remote control controls the speed of the two track mechanisms 3 on land, enabling the armored vehicle to move forward, backward, or turn. In wading mode, when the forward / reverse joysticks and left / right turn joysticks are both moved at a range of 50% or less, the control device controls the propulsion speed of the two spray pumps 4 in the water, enabling the armored vehicle to move forward, backward, or turn on the water surface. The vehicle can turn at a small angle or backward. When in wading mode, and the left and right steering levers are moved by more than 50%, the control device simultaneously controls the propulsion speed of the two spray pumps 4 in the water and the water-pushing speed of the two track mechanisms 3 in the water, so that the armored vehicle body can turn at a large angle on the water surface. When in wading mode, and the forward and backward steering levers are moved by more than 50%, the control device simultaneously controls the propulsion speed of the two spray pumps 4 in the water and the water-pushing speed of the two track mechanisms 3 in the water, so that the armored vehicle body can move forward, backward, land, and enter the water quickly.

[0027] The armored vehicle can freely switch between land mode and wading mode via the remote control switch button to adapt to different driving scenarios: In land mode, by adjusting the walking speed and rotation speed difference of the two track mechanisms 3 through the control device, the armored vehicle can move forward, backward, turn left, turn right or turn around on the spot, etc., making it flexible to operate. In wading mode, graded control is implemented based on the range of joystick movement: when the range of movement of the forward / reverse joystick and the left / right turn joystick is less than or equal to 50%, only the spray pump 4 is used for driving, achieving smooth travel and small-angle turns; when the range of movement of the left / right turn joystick is greater than 50%, the control device controls the track mechanism 3 to participate in water-pushing simultaneously, significantly improving propulsion efficiency and steering torque. By separately controlling the propulsion differential of the two spray pumps 4 in the water and the water-pushing differential of the two track mechanisms 3 in the water, the armored vehicle body can turn at large angles on the water surface; when the range of movement of the forward / reverse joystick is greater than 50%, the control device simultaneously controls the propulsion speed of the two spray pumps 4 in the water and the water-pushing of the two track mechanisms 3 in the water. Speed ​​is crucial for enabling the armored vehicle to move rapidly forward, backward, land, and enter the water. In transition zones between water and land, the track mechanism 3 can directly drive after contact with land, requiring no additional operation. The spray pump 4 continuously provides auxiliary power in the water, quickly completing the bidirectional transition of the armored vehicle from water to land or from land to water. The entire process is smooth and seamless, requiring no manual intervention. By adopting this control logic, mode switching and joystick amplitude are linked for precise adaptation to both water and land scenarios. This effectively solves the problems of performance imbalance between water and land and cumbersome mode switching for armored vehicles, while also overcoming the pain point of requiring manual intervention in transition zones. It achieves easy driving and smooth automatic transitions, significantly improving the user experience and product practicality.

[0028] The control device includes a joystick signal receiving module, a mode switching control module, and a speed adjustment module. The signal output terminals of the joystick signal receiving module and the mode switching control module are electrically connected to the corresponding signal input terminals of the speed adjustment module. The joystick signal receiving module receives signals from the forward / backward joystick and the left / right turn joystick on the remote control. The speed adjustment module receives signals from the switch button on the remote control. The speed adjustment module controls the forward, backward, turn, or mode switching of the armored vehicle body according to the signals sent by the joystick signal receiving module and the mode switching control module. When the user moves the forward / backward joystick on the remote control, the joystick signal receiving module captures the joystick's movement amplitude (e.g., 0%~100%) in real time and converts the amplitude signal into an electrical signal, which is then transmitted to the speed adjustment module. The speed adjustment module generates a corresponding PWM speed control signal (duty cycle increases with amplitude) based on the amplitude value, causing the track mechanism 3 and / or the spray pump 4 to operate at the corresponding speed according to the signal. The mode switching control module receives the signal from the switch button, thereby controlling the speed adjustment module to switch between the land mode control mode (controlling only the drive mechanism 2) and the wading mode (controlling both the spray pump 4 and the drive mechanism 2 simultaneously). The control device can be a single-chip microcomputer or a microprocessor. The aforementioned joystick signal receiving module, mode switching control module and speed adjustment module all use a general-purpose remote control receiving module.

[0029] When the speed control module receives a switch from land mode to wading mode, it controls the spray pump 4 to pre-start at 20% of its rated power for 2-4 seconds and controls the track mechanism 3 to move forward at full power for 2-4 seconds. After 2-4 seconds, the speed control module responds to the electrical signal sent by the joystick signal receiving module. When the speed control module receives a switch from wading mode to land mode, it simultaneously controls the spray pump 4 and the track mechanism 3 to move forward at full power for 2-4 seconds. After 2-4 seconds, the speed control module responds to the electrical signal sent by the joystick signal receiving module. By adopting this logic, when switching to wading mode, the control device will not directly start the spray pump 4 at full power, but will first pre-start it at 20% low power to avoid the armored vehicle body shaking or even overturning due to a sudden large flow impact. The track mechanism 3 can still work for a certain period of time, providing time for transition from land to water. When switching to land mode, the control device can simultaneously control the spray pump 4 and the track mechanism 3 to propel them at full power, thereby fully propelling the armored vehicle body from the water to land, preventing it from running aground.

[0030] The track mechanism 3 includes a drive track 301, a drive wheel 302, and multiple driven wheels 303. The drive wheel 302 is connected to the power output end of the drive mechanism 2. Each driven wheel 303 is rotatably mounted on the base 101. The drive track 301 is tensioned between the drive wheel 302 and each driven wheel 303. The drive track 301 includes multiple track sections 3011 connected in sequence. A deflector plate 3012 is provided in the middle of each track section 3011. The deflector plate 3012 gradually slopes downward from front to back. The front, back, and downward directions of the deflector plate 3012 are determined according to the position of the track section 3011 when it is in the forward section of the drive track 301. By setting up the paddles 3012, when in land mode, the paddles 3012 can play a crawling role, increasing friction, especially when traveling on dirt roads, they can also insert into the mud, further improving grip; when in water wading mode, as the drive track 301 rotates, the paddles 3012 in the forward section can also push the water backward, further increasing the water pushing force, improving propulsion efficiency and steering ability.

[0031] The upper surface of the upper housing 102 is provided with a mounting groove 1021, and a cover plate 1022 is provided on the mounting groove 1021 to cover the mounting groove 1021. The control device is installed in the mounting groove 1021. Since the upper surface of the upper housing 102 is above the water surface after the armored vehicle enters the water, by integrating the control device into the mounting groove 1021 of the upper housing 102, rather than in the inner cavity 1011 of the base 101, the risk of water leakage caused by water flow can be avoided, the probability of water directly contacting the control device can be reduced, the waterproof reliability of the control device can be further improved, and the service life of electronic components can be extended. The cover plate 1022 is made in the shape of the armored vehicle's main hatch cover.

[0032] The drive mechanism 2 includes two planetary geared motors, which are respectively installed in the inner cavity 1011. Each planetary geared motor corresponds one-to-one with one of the two track mechanisms 3, and the power output end of the planetary geared motor is connected to the power input end of the corresponding track mechanism 3. The planetary geared motors are compact in size, and the torque after reduction and torque amplification is sufficient to drive the tracks to overcome land friction, thus meeting the drive requirements of the armored vehicle toy.
