Description

Technical Field

[0001] This utility model belongs to the field of remote control boat equipment technology, and specifically relates to an electric remote control boat hull. Background Technology

[0002] Electric remote-controlled boats typically use a propeller-driven system. The driving efficiency is affected by the blade design and shaft sealing. Traditional propellers are parallel to the water surface, which can easily lead to leakage at the connection and poor driving efficiency. Setting the propeller at a certain angle will make the transmission mechanism complex and prone to failure. Electric remote-controlled boats require remote control in more scenarios. Due to the limitations of the usage scenarios, manual untying is not possible. When the water surface is turbulent, it is even more necessary for electric remote-controlled boats to have an automatic untying and towing function.

[0003] A search revealed that an electric toy boat with prior art authorization announcement number CN 221815303 U includes a hull, motor, battery, propeller, and control circuit board. However, it lacks an automatic towing mechanism, making it inconvenient to use when long-distance operation is required or when the water surface is turbulent. Another prior art authorization announcement number CN 222677165 U describes an automatically resetting dual-propeller remote-controlled boat, which uses a propeller to power the boat. The propeller is positioned parallel to the water surface, leading to potential leaks at the connection points. Furthermore, the lack of a proper propulsion angle results in poor pushing performance. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an electric remote-controlled boat hull. The motor is fixed by an inclined motor bracket, and the motor tilts downward to provide power to the hull, reducing the need for a transmission mechanism and increasing transmission efficiency. The towing mechanism can automatically release the towing rope without the need for manual untying, making it suitable for long-distance operation or use scenarios with large water surface fluctuations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An electric remote-controlled boat hull includes a hull, a drive mechanism, and a towing mechanism; the hull has a centrally symmetrical structure, with a pointed bilge structure at the front end, and the bottom and sides of the hull are connected by a distinct angle line, forming a sharply defined geometric shape. The angle line runs through the entire length of the hull, extending from the bow to the stern; the bottom cross-section of the hull presents a sharp V-shape, extending from the bow to the stern; the stern of the hull is a trapezoidal plane that is wider at the top and narrower at the bottom, and the sides and bottom of the hull are connected by distinct angle lines.

[0007] The hull is equipped with a motor bracket, a limiting block, and a transmission hole. There are two sets of motor brackets symmetrically distributed on both sides of the hull. The overall shape of the motor bracket is a truncated cube. The bottom surface of the motor bracket is fixedly connected to the hull. The top surface of the motor bracket is inclined backward. The motor bracket has a circular groove on its top surface. The circular groove is set from front to back with the horizontal center line on the top surface of the motor bracket as the center. All the overlapping parts of the motor bracket are rounded to form a smooth transition.

[0008] The limiting blocks are arranged in pairs, with the two sets symmetrically distributed and respectively located at the rear end of the motor brackets on both sides of the hull. The overall shape of the limiting blocks is a triangular prism, with the inclined surface of the triangular prism fixedly connected to the hull, and the inclination angle of the triangular prism being consistent with the inclination angle of the motor bracket.

[0009] The transmission hole is provided in two sets, which are symmetrically distributed and respectively set in the middle of the limiting blocks on both sides of the hull. The transmission hole and the groove set on the motor bracket are concentric.

[0010] The drive mechanism consists of two sets, symmetrically distributed on both sides of the hull. Each drive mechanism includes a motor, a drive shaft I, a bearing I, a waterproof washer, a propeller, and a limiting plate I. The motor is mounted in a circular groove on a motor bracket, and its bottom is limited by a limiting block. The motor output is connected to the drive shaft I, which extends out of the hull through a transmission hole. A bearing I is fitted onto the drive shaft I, and the drive shaft I is rotatably connected to the hull via the bearing I. A waterproof washer is located at the rear end of the bearing I, with a trapezoidal circular hole at its center. The outer ring of the waterproof washer contacts the hull, and the inner ring is fitted onto the drive shaft I. A propeller is fixed to the portion of the drive shaft I extending out of the hull, and a limiting plate I is located at the rear end of the propeller.

[0011] The motor controls the rotation of drive shaft I, which is rotatably connected to the hull via bearing I. A waterproof gasket prevents water from leaking into the hull from the connection point. A limiting plate I restricts the position of the propeller. Drive shaft I drives the propeller to rotate, providing power to the hull.

[0012] The towing mechanism is provided in a set and is located at the rear end inside the hull. The towing mechanism includes a motor, a drive shaft II, a bearing II, fastening bolts, a fixing plate, a fixing platform I, a gear, a rack, a limiting groove, a connecting rod, a limiting plate II, a fixing platform II, and a towing rope. The motor is mounted on the fixing plate, which is fixed to the fixing platform I by fastening bolts. The fixing platform I is fixed to the bottom surface inside the hull. The output end of the motor is connected to the drive shaft II. The lower end of the drive shaft II is provided with a gear. A bearing II is provided between the drive shaft II and the fixing plate. The bearing II enables the drive shaft II to rotate and connect with the fixing plate. The gear meshes with the rack, which is located in the limiting groove. The limiting groove is located on the bottom surface inside the hull. A connecting rod is provided at one end of the rack. The limiting plate II is fixed to the fixing platform II, which is located at the rear end outside the hull. The connecting rod passes through the round hole at the lower end of the hull and the limiting plate II. The towing rope is located between the connecting rod and the limiting plate II.

[0013] The motor controls the rotation of the transmission shaft II, which in turn drives the gear to rotate. The gear meshes with the rack, which in turn drives the rack to move within the limiting groove. The rack then drives the connecting rod to move. When the connecting rod passes through the limiting plate II, the towing rope passes between the connecting rod and the limiting plate II. The towing rope pulls the limiting plate II, thus towing the hull. When the connecting rod moves backward and retracts into the hull, the towing rope falls off.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] The bow of the hull features a pointed bilge structure. This structure provides an instantaneous righting moment when the hull tilts during turns or crosswinds, enhancing dynamic stability and generating a sliding effect at high speeds to reduce drag. The bottom of the hull has a sharp V-shaped cross section extending from the bow to the stern. This V-shape effectively cuts through waves at high speeds, reducing hull slap. The motor mount has a rearward-sloping circular groove. By fixing the motor into this groove, the motor tilts downwards and connects to drive shaft I to provide power to the hull. This reduces the number of transmission mechanisms, increases transmission efficiency, and decreases the probability of drive mechanism failure. The towing mechanism automatically releases the towing rope, eliminating the need for manual untying, making it suitable for long-distance operation or use in environments with large surface fluctuations.

[0030] An electric remote-controlled boat hull includes a hull 11, a drive mechanism 12, and a towing mechanism 13. The hull 11 has a centrally symmetrical structure, with a pointed bilge at the front. The bottom of the hull 11 is connected to the sides by a distinct angle line, forming a sharply defined geometric shape. The angle line runs the entire length of the hull 11, extending from the bow to the stern. The pointed bilge structure provides an instantaneous righting moment when the hull 11 turns or tilts in crosswinds, enhancing dynamic stability and generating a gliding effect at high speeds, reducing drag. The bottom cross section of the hull 11 has a sharp V-shape, extending from the bow to the stern. The V-shaped bottom can effectively cut through waves at high speeds, reducing the impact of the hull 11. The stern of the hull 11 is a trapezoidal plane that is wider at the top and narrower at the bottom. The sides of the hull 11 are connected to the bottom by a distinct angle line.

[0031] The hull 11 is equipped with a motor bracket 1101, a limiting block 1102, and a transmission hole 1103. The motor bracket 1101 has two sets symmetrically distributed on both sides of the hull 11. The overall shape of the motor bracket 1101 is a truncated cube. The bottom surface of the motor bracket 1101 is fixedly connected to the hull 11. The upper surface of the motor bracket 1101 is inclined backward. The motor bracket 1101 has a circular groove on its surface. The circular groove is arranged from front to back with the horizontal center line on the surface of the motor bracket 1101 as the center. All the overlapping parts of the edges of the motor bracket 1101 are rounded to form a smooth transition.

[0032] The limiting blocks 1102 are provided in two groups of two, which are symmetrically distributed and respectively set at the rear end of the motor brackets 1101 on both sides of the hull 11.

The output end of the motor 1201 is connected to the drive shaft I 1202. Drive shaft I 1202 extends out of hull 11 through drive hole 1103. Bearing I 1203 is sleeved on drive shaft I 1202. Drive shaft I 1202 and hull 11 are rotatably connected through bearing I 1203. Waterproof washer 1204 is provided at the rear end of bearing I 1203. Waterproof washer 1204 has a trapezoidal hole at its center. The outer ring of waterproof washer 1204 contacts hull 11, and the inner ring is sleeved on drive shaft I 1202. Propeller 1205 is fixed to the part of drive shaft I 1202 that extends out of hull 11. Limiting plate I 1206 is provided at the rear end of propeller 1205.

[0035] The motor 1201 controls the rotation of the drive shaft I 1202. The drive shaft I 1202 is rotatably connected to the hull 11 through the bearing I 1203. The waterproof gasket 1204 prevents water from leaking into the hull 11 from the connection. The limiting plate I 1206 restricts the position of the propeller 1205. The drive shaft I 1202 drives the propeller 1205 to rotate, providing power to the hull 11.

[0036] The towing mechanism 13 is provided in a set and is located at the rear end inside the hull 11. The towing mechanism 13 includes a motor 1301, a drive shaft II 1302, a bearing II 1303, fastening bolts 1304, a fixing plate 1305, a fixing platform I 1306, a gear 1307, a rack 1308, a limiting groove 1309, a connecting rod 1310, a limiting plate II 1311, a fixing platform II 1312, and a towing rope 1313. The motor 1301 is mounted on the fixing plate 1305, and the fixing plate 1305 is fixed to the fixing platform I 1306 by fastening bolts 1304. The fixing platform I 1306 is fixed to the bottom surface inside the hull 11. The output end of the motor 1301 is connected to the drive shaft II 1302. A gear 1307 is provided at the lower end. A bearing 1303 is provided between the drive shaft 1302 and the fixed plate 1305. The drive shaft 1302 and the fixed plate 1305 are rotatably connected through the bearing 1303. The gear 1307 meshes with the rack 1308. The rack 1308 is set in the limiting groove 1309. The limiting groove 1309 is set in the bottom surface inside the hull 11. A connecting rod 1310 is provided at one end of the rack 1308. The limiting plate 1311 is fixed on the fixed platform 1312. The fixed platform 1312 is set at the rear end of the hull 11.

The towing rope 1313 is set between the connecting rod 1310 and the limiting plate 1311.

[0037] The motor 1301 controls the rotation of the transmission shaft II 1302, which in turn drives the gear 1307 to rotate. The gear 1307 meshes with the rack 1308, which in turn drives the rack 1308 to move within the limiting groove 1309. The rack 1308 then drives the connecting rod 1310 to move. When the connecting rod 1310 passes through the limiting plate II 1311, the towing rope 1313 passes between the connecting rod 1310 and the limiting plate II 1311. The towing rope 1313 pulls the limiting plate II 1311, thus towing the hull 11. When the connecting rod 1310 moves backward and retracts into the hull 11, the towing rope 1313 falls off. The towing mechanism 13 can automatically release the towing rope 1313 without manual untying, making it suitable for long-distance operation or use scenarios with large water surface fluctuations.
