Description

Technical Field

[0001] This utility model relates to the field of remote-controlled boats, and in particular to a high-speed remote-controlled boat. Background Technology

[0002] Toy boats on the market now have more and more functions, and their remote control capabilities are stronger than before, greatly enhancing their entertainment value.

[0003] Most remote-controlled toy boats on the market are designed to improve water maneuverability and achieve more dynamic and colorful movements. These boats typically consist of a hull, a motor, and a control circuit board. The motor connects to a propeller via a drive shaft, propelling the boat forward and backward. A remote control wirelessly connects to the control circuit board, allowing the boat to be controlled. These remote-controlled boats require specific water conditions, such as calm water and minimal debris. Currently, high-speed remote-controlled boats for use in open water are also very popular. However, the complex environment of open water means that debris can entangle the propeller of a high-speed boat, causing excessive stress on the drive shaft and resulting in bending and deformation. Because the drive shaft is located inside the hull, the extent of deformation is difficult to detect from the surface. Furthermore, deformation of the drive shaft affects the boat's speed and lifespan. Summary of the Invention

[0004] Therefore, it is necessary to provide a high-speed remote-controlled boat with a drive shaft that is not easily deformed and is easier to detect even if it is deformed.

[0005] This utility model provides a high-speed remote-controlled boat, including A housing having an accommodating cavity formed within it; Controller, the controller being located within the accommodating cavity; A power unit, comprising a motor and a propeller, wherein the motor is located in the accommodating cavity and the motor and the propeller are connected by a drive shaft; The drive shaft includes a shaft body and a sleeve rod. The sleeve rod is made of ceramic material and includes a rod body and a rod head. The diameter of the rod head is larger than the diameter of the rod body. The shaft body is hollow. A positioning groove is provided at the first end of the shaft body, and the second end of the shaft body is open. The rod body is inserted into the shaft body, and the rod head is located in the positioning groove. The first end of the shaft body is connected to the motor, and the second end of the shaft body is connected to the propeller.

[0006] Preferably, the shaft body is made of stainless steel, and the inner diameter of the shaft body is the same as the outer diameter of the sleeve.

[0007] Preferably, the sleeve is made of tempered ceramic.

[0008] Preferably, the housing is provided with a water inlet and a water outlet, and a cooling water pipe is wound around the motor, with both ends of the cooling water pipe connected to the water inlet and the water outlet, respectively.

[0009] Preferably, the housing includes an upper housing and a lower housing, a sealing ring is provided between the upper housing and the lower housing, and the water inlet and the water outlet are both located on the lower housing.

[0010] Preferably, the housing is provided with a fixing position, the motor is locked in the fixing position, and the cooling water pipe is provided with a fixing cover, which is fixed to the housing and fixes the motor and the cooling water pipe.

[0011] Preferably, the rear of the housing is provided with a rudder, and there are two rudders, which are located on both sides of the propeller.

[0012] Preferably, the housing is provided with a direction adjustment device, which is connected to the rudder; the housing is provided with a battery, which is connected to the controller, and the rudder is also electrically connected to the controller.

[0013] Preferably, a tail plate is provided at the rear of the housing, the tail plate is fixed to the rear of the housing and is sealed to the housing, and the rudder and the propeller both pass through the tail plate; a positioning step is provided on the tail plate, and the rudder and the propeller are both located on the upper part of the positioning step.

[0014] Preferably, the propeller includes multiple blades, and the edges of the blades are provided with cutting edges.

[0015] This utility model relates to a remote-controlled boat that connects a motor and a propeller via a drive shaft. The drive shaft includes a shaft body and a sleeve, with the sleeve located inside the hollow shaft body. The shaft body is made of ceramic. When the shaft body bends and deforms, the ceramic sleeve will break and detach from the shaft body. If the drive shaft is deformed, it can be seen directly, and the user can replace the drive shaft immediately, thus avoiding a decrease in the speed or a shortened lifespan of the remote-controlled boat due to drive shaft deformation. In addition, the ceramic sleeve can also strengthen the drive shaft. Because the motor of a high-speed remote-controlled boat rotates quickly and generates too much heat, it can affect the lifespan of the motor. Installing cooling water pipes can extend the lifespan of the motor. Because it has a tailplate, and the tailplate and the housing are separate, it is easier to install the drive shaft and rudder. Because the propeller blades are designed in a blade-like shape, when the propeller of this remote-controlled boat encounters debris in the water and gets entangled, the high-speed rotating blades can cut off the debris without affecting the operation of the boat.

[0020] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] refer to Figure 1-4This utility model provides a high-speed remote-controlled boat, including a hull 1, a controller 2, a battery 3, and a power unit 4. A receiving cavity is formed within the hull 1, where the controller 2 and battery 3 are located and removable. The power unit 4 includes a motor 41 and a propeller 42. The motor 41 is located within the receiving cavity, and the motor 41 and propeller 42 are connected via a drive shaft 43. The propeller 42 is located outside the hull 1, and the drive shaft 43 extends outside the hull 1 and is connected to the propeller 42. (Reference) Figure 3 The drive shaft 43 includes a shaft body 431 and a sleeve 432. The sleeve 432 includes a rod body 4321 and a rod head 4322. The diameter of the rod head 4322 is larger than the diameter of the rod body 4321. The shaft body 431 is hollow. A positioning groove 4311 is provided at the first end of the shaft body 431, and the second end of the shaft body 431 is open. The rod body 4321 is inserted into the shaft body 431, and the rod head 4322 is located in the positioning groove 4311. The sleeve 432 is made of a rigid material, such as ceramic. The first end of the shaft body 431 is connected to the motor 41, and the second end of the shaft body 431 is connected to the propeller 42. When the shaft body 431 bends and deforms, the ceramic sleeve 432 will break and fall out of the shaft body 431. If the drive shaft 43 is deformed, it will be clearly visible, and the user can replace the drive shaft 43 to avoid the remote control boat slowing down or shortening its service life due to the deformation of the drive shaft 43.

[0023] In a preferred embodiment, the shaft body 431 is made of stainless steel, which provides better strength. The sleeve 432 is made of ceramic material, and the inner diameter of the shaft body 431 and the outer diameter of the sleeve 432 are the same. The wall thickness of the shaft body 431 is approximately 2-3 mm to ensure its strength.

[0024] In a further preferred embodiment, the sleeve 432 is made of tempered ceramic, and the tempered ceramic sleeve can also strengthen the drive shaft 43.

[0025] refer to Figure 2 In a preferred embodiment, the housing 1 is provided with a water inlet 11 and a water outlet 12, and a cooling water pipe 5 is wound around the motor 41. The two ends of the cooling water pipe 5 are connected to the water inlet 11 and the water outlet 12, respectively. The cooling water pipe 5 is made of aluminum or aluminum alloy, which has better thermal conductivity.

[0026] refer to Figure 1 and Figure 2In a preferred embodiment, the housing 1 includes an upper housing and a lower housing, with a sealing ring provided between the upper and lower housings. Furthermore, a sealing ring groove is provided on the lower housing. The upper and lower housings press the sealing ring together to achieve a seal. The water inlet 11 and water outlet 12 are both located on the lower housing. The water inlet 11 and water outlet 12 are immersed in water, allowing the cooling water pipe 5 to be filled with water and thus providing cooling.

[0027] refer to Figure 1 and Figure 2 In a preferred embodiment, a fixing position is provided on the housing 1, and the motor 41 is locked in the fixing position. A fixing cover 6 is provided on the outside of the cooling water pipe 5, and the fixing cover 6 is fixed to the housing 1, fixing the motor 41 and the cooling water pipe 5. The fixing cover 6 is hollow, and the cooling water pipe 5 extends from the hollow to the inlet 11 and the outlet 12. refer to Figure 1 and Figure 2 In a preferred embodiment, a rudder 7 is provided at the rear of the housing 1. There are two rudders 7, located on either side of the propeller 42. They are used to adjust the direction of the remote-controlled boat.

[0028] refer to Figure 1 and Figure 2 In a preferred embodiment, a direction adjustment device is provided inside the housing 1, and the direction adjustment device is connected to the rudder 7. A battery 3 is provided inside the housing 1, and the battery 3 is connected to the controller 2. The rudder 7 is also electrically connected to the controller 2.

[0029] refer to Figure 1 and Figure 2 In a preferred embodiment, a tail plate 8 is provided at the rear of the housing 1. The tail plate 8 is fixed to the rear of the housing 1 and is sealed to the housing 1. Both the rudder 7 and the propeller 42 pass through the tail plate 8. The tail plate 8 and the housing 1 are separate, making it easier to install the drive shaft 43 and the rudder 7. A positioning step 81 is provided on the tail plate 8, and both the rudder 7 and the propeller 42 are located on the upper part of the positioning step 81. Specifically, the positioning step 81 has a lower center and higher sides, and the rudder 7 is positioned higher than the propeller 42.

[0030] refer to Figure 4In a preferred embodiment, the propeller 42 includes multiple blades 421, each blade 421 having a cutting edge 4211. When the propeller 42 of the remote-controlled boat becomes entangled with debris in the water, the high-speed rotating blades 421 can cut the debris without affecting the boat's operation. Specifically, the cutting edge 4211 is located on the opposite side of the rotation direction of the blades 421. When the propeller 42 is entangled with debris, the remote control can reverse the propeller 42 to cut off the debris. Furthermore, the cutting edge 4211 is relatively short and positioned close to the central axis of the propeller 42 to avoid accidental injury. As the propeller 42 rotates in the opposite direction, it pushes the entangled debris towards its central axis. When the debris approaches the cutting edge 4211 at the central axis, the rapidly rotating cutting edge 4211 can easily cut off the debris.

[0031] The remote-controlled boat of this invention connects the motor 41 and the propeller 42 via a drive shaft 43. The drive shaft 43 includes a shaft body 431 and a sleeve 432. The sleeve 432 is located inside the hollow shaft body 431. The shaft body 431 is made of ceramic. When the shaft body 431 bends and deforms, the ceramic sleeve 432 will break and fall out of the shaft body 431. If the drive shaft 43 is deformed, it can be seen directly, and the user can replace the drive shaft 43 to avoid the remote-controlled boat slowing down or shortening its service life due to the deformation of the drive shaft 43. In addition, the ceramic rod can also strengthen the drive shaft 43. Because the motor 41 of the high-speed remote control boat rotates quickly, excessive heat generation will also affect the service life of the motor 41. Setting up a cooling water pipe 5 can improve the service life of the motor 41. Because of the tailplate 8, which is a separate unit from the housing 1, it is easier to install the drive shaft 43 and the rudder 7. Since the blades 421 of the propeller 42 are blade-shaped, when the propeller 42 of the remote-controlled boat encounters debris in the water, the high-speed rotating blades 421 can cut the debris without affecting the operation of the boat.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above embodiments merely illustrate specific implementations of the utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
