Key components such as bearings and seals are installed inside. In addition, the front cover also has functions such as waterproof and dustproof to keep the inside of the motor clean and safe. The rear cover is usually located at the rear of the motor, and serves as the end cover and bearing seat of the motor. Its main function is to support the motor rotor 3 and fix the motor stator 4. The controller 1 is fixed on the housing 21 for fixing the stator 4, that is, the controller 1 is fixed on the rear cover.

[0039] Please refer to Figures 2 to 3 The controller 1 includes a mounting seat 11, a protective cover 12 and a control board 13.

A plurality of electronic components 131 are arranged on the control board 13.

[0040] In the technical solution of the utility model, the protective cover 12 and the mounting seat 11 are combined to form the accommodating cavity 121, so as to protect the control board 13 in the accommodating cavity 121, so that the control board 13 will not be affected by splashing water vapor. Compared with the conventional form of potting glue, the assembly is simpler and the protection is more comprehensive. At the same time, the setting of the protective cover 12 isolates the hardware on the controller 1 to prevent people from touching it. At the same time, it can avoid safety risks such as short circuit caused by damage to the controller 1 during the assembly and testing process of the motor, thereby improving the efficiency and safety of motor assembly.

[0041] In this embodiment, the mounting base 11 serves as a mounting base for the control board 13 and has the effect of fixing the control board 13 .

[0042] Considering that the sizes of the multiple electronic components 131 are different, in one embodiment, the accommodating cavity 121 is formed with multiple cavity segments distributed along the second direction, and the multiple cavity segments have different sizes in the first direction. The multiple cavity segments are used to accommodate multiple electronic components 131 of different heights, so that the protective cover 12 and the control board 13 are more closely matched, and the overall volume of the controller 1 is smaller.

[0043] It should be understood that the plurality of cavity segments may be arranged in a step-by-step increasing or step-by-step decreasing manner along the second direction, or may be arranged in a staggered manner in the second direction, depending on the arrangement design of the electronic components 131 on the control board 13 .

[0044] In other embodiments, the inner cavity of the protective cover 12 is arranged in a stepped shape, that is, the outer surface of the corresponding protective cover 12 is stepped, so as to be compatible with the multiple electronic components 131. It should be understood that the stepped shape forms multiple stepped cavity sections inside the protective cover 12, and each stepped cavity section accommodates multiple or one electronic component 131.

[0045] In order to facilitate assembly, in one embodiment, the protective cover 12 and the mounting seat 11 are connected by a buckle structure 14. The protective cover 12 is fixed to the mounting seat 11 in advance by the buckle structure 14, so that the controller 1 forms a whole, which makes it easier to assemble the motor.

[0046] It should be understood that one of the protective cover 12 and the mounting seat 11 is provided with a buckle, and the other is provided with a buckle hole, so as to cooperate. Considering the stability of the buckle, the buckle structure 14 can be provided in plurality. In this embodiment, two buckle structures 14 are provided along the second direction, and the two buckle structures 14 are located on both sides of the control board 13.

[0047] In order to ensure a tight connection, in some embodiments, the controller 1 further includes at least one connecting member 15, and the connecting member 15 is arranged through the mounting seat 11 and the protective cover 12. The utility model does not limit the specific form of the connecting member 15, which can be a structure such as a screw, a pin, etc. The connecting member 15 is used to be screwed on the rear end cover of the motor assembly 100, that is, the mounting seat 11, the protective cover 12 and the rear end cover are locked together through the connecting member 15, thereby enhancing the matching stability of the protective cover 12 and the mounting seat 11.

[0048] It should be understood that, during the matching, the protective cover 12 can be fitted with the rear end cover, or the mounting base 11 can be fitted with the rear end cover. In this embodiment, the protective cover 12 is fitted with the rear end cover, and the electronic components 131 on the control board 13 are arranged toward the rear end cover.

[0049] In this embodiment, the connecting member 15 is provided as a screw, and a plurality of screws are provided, and the plurality of screws correspond to the peripheral edges of the mounting seat 11 and the protective cover 12 .

[0050] Considering the installation of the control panel 13, please refer to Figure 1 An insulating gasket 16 is provided between the control board 13 and the mounting seat 11. It should be understood that the upper part of the control board 13 is the side where the electronic component 131 is provided, and the bottom of the control component is the power connection part. The insulating gasket 16 is used to insulate the control board 13 to prevent the mounting seat 11 from being connected to electricity.

[0051] In addition, please refer to Figure 4 The outer surface of the mounting seat 11 is provided with a plurality of heat dissipation ribs 111 arranged at intervals. Thus, the controller 1 is cooled, and the heat emitted by the electronic components 131 of the control board 13 is directed to the mounting seat 11, and then the heat is dissipated by the heat dissipation ribs 111, so as to avoid the high temperature of the controller 1 affecting the use.

[0052] It should be understood that the intervals between adjacent heat dissipation ribs 111 can be the same or different. In the present embodiment, the plurality of heat dissipation ribs 111 are arranged at intervals in the second direction and are not evenly distributed on the entire side of the mounting base 11. A contact portion is provided on the side of the control board 13 facing away from the electronic component 131. The contact portion is in contact with the insulating gasket 16 for conducting heat through physical contact. A plurality of heat sinks are concentrated at the position of the mounting base 11 corresponding to the contact portion.

[0053] Please refer again Figure 1In this embodiment, the controller 1 is composed of a protective cover 12, a control board 13, an insulating gasket 16, and a mounting seat 11. A buckle hole is provided on the mounting seat 11, and a buckle is provided on the protective cover 12. When assembling the motor of the utility model, the protective cover 12, the control board 13, the insulating gasket 16, and the mounting seat 11 are arranged along the first direction, and the protective cover 12 is fixed in the buckle hole on the mounting seat 11 by buckles, so that the protective cover 12 completely covers and protects the control board 13 to form a complete controller 1, and then the entire controller 1 is assembled to the rear end cover of the motor by screws, so that the controller 1 is locked with the housing structure 2. This can not only make the assembly simple, the protective cover 12 is not easy to slip off, but also the control board 13 can be tightly wrapped by the protective cover 12 to prevent water vapor from damaging it. At the same time, the use of integrated screw locking can also reduce the installation process and simplify the structure. During use, the motor assembly 100 can prevent people from touching the electronic components 131 on the control board 13, reduce safety risks such as short circuits caused by damage to the controller 1 during motor assembly and testing, and improve the efficiency and safety of motor assembly.
