Description

Technical Field

[0001] The utility model relates to the technical field of motors for hydrofoils, in particular to an in-built drive waterproof motor. Background Art

[0002] The waterproof motors and electronic speed regulators used in existing hydrofoils are two independent components. When working together, the operation is often interrupted due to the high temperature of the electronic speed regulator caused by heat generation. Currently, most solutions to the heat generation problem use water pipes to supply water to the electronic speed regulator, and the electronic speed regulator is cooled through water circulation. Moreover, since the hydrofoil products are used in water, in addition to solving the heat dissipation problem of the electronic speed regulator, it is also necessary to do a good job in waterproofing the electronic speed regulator. The operation is relatively troublesome and will affect the normal use and battery life of the hydrofoil. Therefore, those skilled in the art have provided an in-built drive waterproof motor to solve the problems raised in the above background art. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an in-built drive waterproof motor, which includes a motor body. A motor output shaft is arranged on the front side of the motor body, and a rear cover is installed on the rear side thereof.

[0004] An electronic speed regulation mechanism is arranged at the rear end inside the motor body. The electronic speed regulation mechanism is fixed to the rear cover and transfers its own heat to the outer shell of the entire motor body through the rear cover to exchange heat with water for heat dissipation.

[0005] Preferably: The electronic speed regulation mechanism includes a MOS board, which is installed on the inner wall of the rear cover by screws, and thermal conductive silicone grease is filled between the MOS board and the rear cover.

[0006] Preferably: Both the rear cover and the outer shell of the motor body are made of aluminum.

[0007] Preferably: Multiple connecting wires are arranged on the MOS board, and the connecting wires are connected to the motor drive structure inside the motor body.

[0008] Technical Effects and Advantages of the Utility Model

[0009] In the utility model, the MOS board of the electronic speed regulation mechanism is closely attached to the rear cover of the motor. The rear cover of the motor is closely attached to the MOS board on the electronic speed regulation mechanism through thermal conductive silicone grease. The aluminum rear cover can well absorb the heat on the MOS board and transfer it to the outer shell of the entire motor. After contacting with water, through heat transfer by temperature difference, the heat is directly dissipated into the water, so that the electronic speed regulation mechanism can work for a longer time under a larger current and the heat dissipation of the electronic speed regulation mechanism is better.

[0010] In the present utility model, since the electronic speed control mechanism is directly placed inside the motor, an integrated design of the electronic speed control mechanism and the motor is achieved, solving the operation problem of the electronic speed control mechanism of the motor. The installation is more convenient and rapid, and it is wrapped by the aluminum shell of the motor to form a waterproof integration of the motor and the electronic speed control mechanism, solving the problem of independent waterproofing of the motor and the electronic speed control mechanism.

[0014] The present utility model will be further described in detail below with reference to the drawings and specific embodiments. The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0015] Embodiment

[0016] Please refer to Figure 1 , in this embodiment, a built-in drive waterproof motor is provided, including a motor body 1. A motor output shaft 2 is provided on the front side of the motor body 1, and a rear cover 3 is installed on the rear side thereof. The rear cover 3 realizes the sealing of the motor body 1. Moreover, inside the motor body 1, an electronic speed control mechanism 4 is provided at the rear end thereof. The electronic speed control mechanism 4 is fixed on the inner wall of the rear cover 3, so that the electronic speed control mechanism 4 and the motor form an integral structure, and there is no need to perform waterproofing and installation on it, saving a lot of cumbersome steps;

[0017] In the electronic speed control mechanism 4, the electronic speed control mechanism 4 includes a MOS board 41. The MOS board 41 is installed on the inner wall of the rear cover 3 through screws 42. Moreover, a heat-conducting silicone grease is filled between the MOS board 41 and the rear cover 3, which can make the heat generated on the MOS board 41 better conduct to the rear cover 3, and then the rear cover 3 transfers the heat to the outer shell of the motor. The outer shells of the rear cover 3 and the motor body 1 are both made of aluminum, which can conduct and absorb heat well. When the motor is placed in water, heat exchange with water can be realized, achieving a good heat dissipation effect. Multiple connecting wires 43 are also connected to the MOS board 41. The connecting wires 43 are connected to the motor drive structure inside the motor body 1 to realize the electrical connection and control between the electronic speed control mechanism 4 and the motor.

[0018] In this utility model, by integrating the electronic speed control mechanism 4 inside the motor body 1 and making the MOS board 41 of the electronic speed control mechanism 4 closely adhere to the rear cover 3 of the motor, the rear cover 3 of the motor is closely attached to the MOS board 41 on the electronic speed control mechanism 4 through thermal conductive silicone grease. According to the specific heat capacity of the substance Q = c * m * (T2 - T1), it can be concluded that the aluminum rear cover 3 can well absorb the heat on the MOS board 41 and transfer it to the entire motor housing. After the aluminum housing of the motor absorbs the heat of the electronic speed control mechanism 4 and comes into contact with water, through heat transfer by temperature difference, the heat is directly dissipated into the water, so that the electronic speed control mechanism 4 can work at a larger current for a longer time, and the heat dissipation of the electronic speed control mechanism 4 is better;

[0019] Moreover, since the electronic speed control mechanism 4 is directly placed inside the motor, the integrated design of the electronic speed control mechanism 4 and the motor is realized, solving the operation problem of the electronic speed control mechanism 4 of the motor. The installation is more convenient and fast, and it is wrapped by the aluminum housing of the motor to form a waterproof integration of the motor and the electronic speed control mechanism 4, solving the problem of independent waterproofing of the motor and the electronic speed control mechanism 4.

[0020] Obviously, the described embodiments are only part of the embodiments of this utility model, rather than all embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model shall be implemented by conventional means in the art without special instructions and limitations.
