Description

Technical Field

[0001] This application relates to the field of marine motor technology, specifically a marine motor. Background Technology

[0002] Marine motors, also known as marine electric motors, are electrical devices widely used on ships. They convert electrical energy into mechanical energy, which in turn drives other devices or equipment.

[0003] Because marine motors are used in aquatic environments, they are mostly encased in a sealed, waterproof casing. However, this sealed casing also prevents the efficient dissipation of heat generated by the internal motor during operation. After prolonged use, the engine area can easily burn the operators, posing a safety hazard.

[0004] Therefore, this application provides a marine motor to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a marine motor designed to address the problem mentioned in the background art where existing marine motors suffer from poor heat dissipation efficiency due to the poor sealing of their waterproof protective casing, which poses a safety hazard.

[0006] To achieve the above objectives, this application provides the following technical solution: a marine motor, comprising a drive mechanism, a coupling mechanism connected to the output end of the drive mechanism, a propulsion turbofan connected to the other end of the coupling mechanism, and a steering rod fixedly mounted on the drive mechanism.

[0007] The drive mechanism includes a housing and a cover fixedly installed at the opening of the housing. A differential gearbox with its output end connected to the input end of the coupling mechanism is fixedly installed inside the housing. A motor with its output end connected to the input end of the differential gearbox is also fixedly installed inside the housing.

[0008] The motor has a fin matrix on its side for heat dissipation, and a cooling fan is embedded in the fin matrix.

[0009] The outer casing has an air inlet on the side near the fin matrix, and the cover has an air outlet coaxial with the cooling fan. Protective mesh covers are fixedly connected to both the air inlet and the air outlet. This design of the fin matrix and cooling fan on the side of the motor effectively improves the heat dissipation efficiency of the marine motor. This not only prevents the motor from overheating but also extends its service life. Due to the improved heat dissipation efficiency, the heat generated by the marine motor during operation can be dissipated more quickly, reducing the temperature of the engine components and thus reducing the risk of burns to operators, enhancing safety during use.

[0010] Preferably, the end of the air outlet near the fin matrix has a docking cylinder that connects with the cooling fan.

[0011] Preferably, both the air inlet and the air outlet have waterproof and breathable membranes near the inner side of the protective mesh cover.

[0012] Preferably, the coupling mechanism includes a connecting shaft whose top end is connected to the output end of the differential gearbox, a sleeve fitted outside the connecting shaft, a bearing seat fixedly installed on the top end of the sleeve and connected to the drive mechanism at the other end for fixed installation on the hull, and a universal coupling fixedly installed inside the sleeve by bearings and connected at both ends to the bottom end of the connecting shaft and the input end of the propulsion turbofan, respectively.

[0013] Preferably, the propulsion turbofan is oriented in the same direction as the air outlet.

[0014] Preferably, the propulsion turbine housing is fixedly installed on the side of the bottom end of the sleeve.

[0015] This marine motor, through the design of the fin matrix and cooling fan on the side of the motor, effectively improves the heat dissipation efficiency. This not only prevents the motor from overheating but also extends its service life. Due to the improved heat dissipation efficiency, the heat generated by the marine motor during operation can be dissipated more quickly, reducing the temperature of the engine parts and thus reducing the risk of burns to operators, thereby enhancing the safety of use.

[0016] The protective mesh inside the air inlet and outlet of this marine motor effectively prevents external debris from entering the casing, protecting the motor and other internal components from damage. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This embodiment provides a marine motor, such as Figures 1-3 As shown, the marine motor includes a drive mechanism 1, a coupling mechanism 2 connected to the output end of the drive mechanism 1, a propulsion turbofan 3 connected to the other end of the coupling mechanism 2, and a steering rod 4 fixedly mounted on the drive mechanism 1.

[0029] The drive mechanism 1 includes a housing 11 and a cover 12 fixedly installed at the opening of the housing 11. A differential gearbox 13 with its output end connected to the input end of the coupling mechanism 2 is fixedly installed inside the housing 11. A motor 14 with its output end connected to the input end of the differential gearbox 13 is fixedly installed inside the housing 11.

[0030] The motor 14 has a fin matrix 141 on its side for heat dissipation, and a cooling fan 142 is embedded in the fin matrix 141.

[0031] The outer casing 11 has an air inlet 111 on the side near the fin matrix 141, and the cover 12 has an air outlet 121 coaxial with the cooling fan 142. A protective mesh cover 122 is fixedly connected inside both the air inlet 111 and the air outlet 121.

[0032] When in use, when the motor 14 starts and drives the differential gearbox 13 and propulsion turbofan 3, heat is generated inside the motor 14. The heat is transferred to the external environment through the fin matrix 141 on the side of the motor 14. At the same time, the cooling fan 142 starts to rotate, drawing in cold air from the outside through the air inlet 111 on the outer casing 11. After passing through the motor 14 and the fin matrix 141, the hot air is discharged from the air outlet 121 on the cover 12, forming an effective heat dissipation cycle. The protective mesh cover 122 inside the air inlet 111 and the air outlet 121 can prevent external debris from entering the interior and affecting the normal operation of the motor.

[0033] Furthermore, the end of the air outlet 121 near the fin matrix 141 has a docking cylinder 123 that docks with the cooling fan 142; the docking cylinder 123 serves as a transition structure between the cooling fan 142 and the air outlet 121, ensuring that the hot air blown out by the cooling fan 142 can be smoothly discharged through the air outlet 121; the shape and size of the docking cylinder 123 match the cooling fan 142, so that the hot air will not be excessively obstructed during the flow.

[0034] Furthermore, both the air inlet 111 and the air outlet 121 have waterproof and breathable membranes on the inner side near the protective mesh cover 122. The waterproof and breathable membrane is a material with a microporous structure that allows air and water vapor molecules to pass through, but can block water droplets and larger particles. Installing the waterproof and breathable membrane on the inner side of the air inlet 111 and the air outlet 121 near the protective mesh cover 122 can ensure that air circulation is maintained while preventing water mist, dust and other debris from entering the motor.

[0035] Specifically, the coupling mechanism 2 includes a connecting shaft 21 whose top end is connected to the output end of the differential gearbox 13, a sleeve 22 fitted outside the connecting shaft 21, a bearing seat 5 fixedly installed on the top end of the sleeve 22 and connected to the drive mechanism 1 at the other end for fixed installation on the hull, and a universal coupling 23 fixedly installed inside the sleeve 22 via bearings and connected at both ends to the bottom end of the connecting shaft 21 and the input end of the propulsion turbofan 3, respectively. The coupling mechanism 2 is connected to the output end of the differential gearbox 13 via the connecting shaft 21, transmitting power to the universal coupling 23 inside the sleeve 22. The universal coupling 23 has multi-directional transmission characteristics and can adapt to power transmission requirements at different angles. The input end of the propulsion turbofan 3 is connected to the other end of the universal coupling 23, thereby receiving power and starting to rotate. The bearing seat 5 is fixedly installed on the hull, providing support and positioning for the sleeve 22.

[0036] It should be noted that the propulsion turbofan 3 and the air outlet 121 are aligned, and the outer shell of the propulsion turbofan 3 is fixedly installed on the side of the bottom end of the sleeve 22. The alignment of the propulsion turbofan 3 and the air outlet 121 is conducive to the smooth discharge of hot air and avoids the heat dissipation problem caused by the accumulation of hot air inside the motor.

[0037] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
