Description

Technical Field

[0001] This utility model relates to the field of kinetic energy recovery technology for outboard motors, and in particular to a kinetic energy recovery component for outboard motors. Background Technology

[0002] Outboard motors are typically started via an external battery, which drives the starter motor to start the equipment.

[0003] Meanwhile, batteries often power other devices such as lights, so they need to have sufficient capacity to meet the needs of a certain period of time. However, large-capacity batteries inevitably have a large size, which takes up a lot of space inside the boat and makes it difficult to move the batteries each time they are charged.

[0004] To extend battery life, energy recovery devices are typically installed, allowing the kinetic energy generated when the outboard motor starts to generate electricity to replenish the battery. However, due to the relatively enclosed environment of the outboard motor, the electromagnetic reaction during energy recovery generates heat. This heat, along with the heat generated by the outboard motor itself, can affect the magnets or coil circuits in the energy recovery components, shortening their lifespan and increasing the failure rate. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a kinetic energy recovery component for an outboard motor, thereby solving the problem that the kinetic energy recovery component cannot dissipate heat in a timely manner during operation within the outboard motor equipment, which affects the service life of the equipment in the kinetic energy recovery component.

[0006] The technical solution of this utility model is as follows: a kinetic energy recovery component for an outboard motor, including a rotating shaft connected to the power unit of the outboard motor, a flywheel at the end of the rotating shaft, the flywheel being a bowl-shaped structure with its opening facing downwards, an annular partition at the bottom of the flywheel, forming a receiving space between the partition and the flywheel, a magnetic component inside the receiving space, several inclined grooves being evenly and centripetally opened on the surface of the partition, the inclined grooves penetrating both sides of the partition to form a centrifugal fan, an equipment plate being fitted on the side of the rotating shaft near the bottom of the flywheel, several coils being distributed in an annular pattern on the top of the equipment plate, the bottom of the coils passing through the equipment plate and electrically connected to a battery.

[0007] Furthermore, the coil is positioned on the surface of the device board close to the partition, with a gap between the partition, the magnetic component, and the coil, ensuring that the coil can generate electricity under the influence of the magnetic component, while simultaneously not contacting the partition, thus ensuring smooth rotation of the flywheel.

[0008] Furthermore, the equipment plate is fixedly connected to the outboard motor. The equipment plate has a through hole with a diameter larger than the shaft at its center. It is fitted onto the outside of the shaft through the through hole, so that the equipment plate does not come into contact with other structures and maintains a certain distance from other structures to avoid the equipment plate absorbing heat and affecting other components.

[0009] Furthermore, the edge of the device plate is provided with grooves extending to the bottom of the coil. Several grooves are radially distributed along the center of the device plate, and the grooves make the edge of the device plate resemble a finned heat exchanger, thereby increasing the heat dissipation efficiency of the device plate.

[0010] Furthermore, a connecting component is provided at the bottom of the device board, and the connecting component connects each coil in series and provides leads to the battery.

[0011] Furthermore, the device plate has annularly distributed air inlets on the side near the central perforation to distinguish the air movement path during the cooling process and separate the air inlet and outlet parts.

[0012] Furthermore, the partition is integrally formed with the flywheel, and the inclined groove on its surface extends laterally through the partition, with the height of the inclined groove being less than the height of the partition.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model separates the magnetic component and the coil by setting a partition inside the flywheel, so that the heat emitted by the two structures does not affect each other. At the same time, the surface of the partition is opened with an inclined groove to prevent the partition from affecting the magnetic force acting on the coil. When the flywheel rotates, it drives the partition to rotate. At this time, the centrifugal fan formed by the inclined groove on the surface of the partition can draw in the outside air along the surface of the equipment plate, accelerate it and then discharge it. In this process, the air is used to cool the coil and the magnetic component.

[0015] 2. The equipment plate in this utility model can absorb heat and store the heat inside the outboard motor, thus preventing heat buildup inside the outboard motor. At the same time, when the flywheel rotates rapidly and drives the air out, the air passes through the grooves on the surface of the equipment plate, carrying away the heat inside the equipment plate, which can reduce the temperature of the equipment plate and allow the equipment plate to absorb heat better, thereby reducing the overall temperature inside the outboard motor.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figure 1-5 As shown, a kinetic energy recovery component for an outboard motor includes a rotating shaft 1 connected to the power unit of the outboard motor. A flywheel 2 is provided at the end of the rotating shaft 1. The flywheel 2 is shaped like a bowl with its opening facing downwards. An annular partition 3 is provided at the bottom of the flywheel 2. An accommodating space is formed between the partition 3 and the flywheel 2. A magnetic component 4 is provided inside the accommodating space. Several inclined grooves 5 are evenly and centripetally opened on the surface of the partition 3. The partition 3 and the flywheel 2 are integrally formed. The inclined grooves 5 on its surface penetrate the partition 3 laterally. The height of the inclined grooves 5 is less than the height of the partition 3.

[0024] The inclined groove 5 passes through both sides of the partition 3 to make the partition 3 form a centrifugal fan. The side of the rotating shaft 1 near the bottom of the flywheel 2 is fitted with an equipment plate 6. The equipment plate 6 is fixedly connected to the outboard motor. The center of the equipment plate 6 has a through hole with a diameter larger than that of the rotating shaft 1. The equipment plate 6 is fitted on the outside of the rotating shaft 1 through the through hole so that the equipment plate 6 does not come into contact with other structures and maintains a certain distance from other structures to avoid the equipment plate 6 absorbing heat and affecting other components. Several coils 7 are distributed in a ring on the top of the equipment plate 6. The bottom of the coils 7 passes through the equipment plate 6 and is electrically connected to the battery.

[0025] A connecting component is provided at the bottom of the device plate 6. The connecting component connects each coil 7 in series and provides leads to the battery. The coil 7 is located on the surface of the device plate 6 near the partition 3. A gap is left between the partition 3, the magnetic component 4, and the coil 7 to ensure that the coil 7 can generate electricity under the influence of the magnetic component 4, while not contacting the partition 3, ensuring smooth rotation of the flywheel 2. A groove extending to the bottom of the coil 7 is provided at the edge of the device plate 6. Several grooves are radially distributed along the center of the device plate 6. The grooves make the edge of the device plate 6 resemble a finned heat exchanger, increasing the heat dissipation efficiency of the device plate 6. A ring of air inlets is provided on the side of the device plate 6 near the central perforation to distinguish the movement path of air during the cooling process and separate the air inlet and outlet parts.

[0026] The working principle of this utility model is as follows: First, after the outboard motor is started normally during use, the power part keeps the rotating shaft 1 in a rotating state. When the rotating shaft 1 rotates, it drives the flywheel 2 to rotate. When the flywheel 2 rotates, it drives the magnetic component 4 to move. During the movement, the magnetic force of the magnetic component 4 acts on the coil 7, causing the coil 7 to generate electricity. The electricity generated by the coil 7 is rectified and sent to the battery. During this process, the magnetic component 4 and the coil 7 interact and the temperature rises.

[0027] As the flywheel 2 rotates, the partition 3 rotates along with it. The inclined groove 5 on the surface of the partition 3 causes the partition 3 to form a centrifugal fan that draws air from the bottom up through the air on the surface of the equipment plate 6 into the flywheel 2, and then discharges it to the surroundings. The discharged air passes through the coil 7 and the magnetic component 4 to remove their heat, and then is discharged outwards through the space between the equipment plate 6 and the flywheel 2.

[0028] When air passes through the equipment plate 6, it enters the groove at the edge of the equipment plate 6, increasing the contact area with the equipment plate 6 and carrying out the temperature inside the equipment plate 6. The high-temperature air is finally discharged outward along the exhaust and heat dissipation part of the outboard motor.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
