[0001] The utility model relates to motor technical field, especially relate to a motor structure of temperature and noise can be reduced. BACKGROUND

[0002] Motor technology has experienced rapid development since the middle of the nineteenth century, from the initial DC motor to AC motor, and then to the emergence of high-efficiency energy-saving motor such as brushless DC motor and permanent magnet synchronous motor. With the improvement of industrial automation level and the increasing demand for energy saving and emission reduction, as the key equipment for power conversion, the requirements for motor in efficiency, reliability and operating characteristics are becoming higher and higher. Especially in terms of heat dissipation and noise reduction, the traditional motor structure often faces great challenges. The traditional motor usually adopts natural cooling or simple fan cooling method, which is not effective when the motor runs at high speed, easily leading to rapid temperature rise of the motor, affecting the performance and service life of the motor; at the same time, the noise problem of traditional motor has been bothering users, especially in the fields of precision instruments, medical equipment, household appliances, etc., the excessive noise of motor not only affects the user experience, but also may cause environmental noise pollution.

[0003] In recent years, in order to solve the above problems, some improvement measures have appeared in the industry, such as increasing the area of cooling fins, optimizing the design of air duct, using low noise bearings, etc. However, these methods are mostly optimized for single factor, lack of systematic solution, and in actual application, due to the limited space inside the motor, how to effectively use the limited space to achieve better heat dissipation and noise reduction effect becomes a new problem. In addition, some existing improvement schemes have high manufacturing cost, which is not conducive to large-scale popularization and application. Therefore, it is particularly urgent to develop a motor structure which can effectively reduce temperature and noise without significantly increasing cost. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies in the prior art, the utility model provides a motor structure capable of reducing temperature and noise, comprising a shell, one end of the shell is provided with a widened part, one end of the widened part is connected with a motor front cover, a plurality of blade-shaped reinforcing sheets are welded on the front part of the motor front cover, first ventilation openings are arranged between adjacent blade-shaped reinforcing sheets, a horn-shaped wind deflector is arranged in the inside of the widened part, a mixed type blade is arranged in the inside of the horn-shaped wind deflector, and a motor rear cover is connected to one end of the shell.

[0005] A second ventilation opening is formed in the rear part of the motor rear cover, and a third ventilation opening is formed in the left and right sides of the motor front cover.

[0006] Two connecting blocks are fixedly connected to the top of the motor front cover, and mounting holes are formed in the connecting blocks.

[0007] The top of the motor front cover is fixedly connected with a central positioning plate, and the lower part of the motor front cover is fixedly connected with a heightening plate.

[0008] The inside of the shell is provided with a stator and a rotor, the first output shaft of the rotor is in transmission connection with a mixed type fan blade, the first output shaft is fixedly connected with a first gear, the first gear is in transmission connection with a second gear, and the second gear is in transmission connection with a second output shaft.

[0009] The first sleeve and the second sleeve are fixedly connected to the motor front cover, the second sleeve is connected with an end cover through bolts, and the right side of the first sleeve is provided with a notch part.

[0010] Compared with the prior art, the utility model has the advantages that:

[0011] 1. By setting a widened part at one end of the shell and installing a horn-shaped wind deflector and a mixed type fan blade inside, the air flow path is optimized. The design of the widened part increases the space at the front end of the motor, providing a larger flow cross section for the airflow and reducing airflow resistance, thereby improving cooling efficiency. The horn-shaped wind deflector not only guides the direction of airflow entering the motor interior, ensuring that the airflow uniformly covers the entire motor, but also plays a certain sound attenuation role, reducing the noise generated by airflow impact. The mixed type fan blade further enhances the advantages of this design, as it generates strong suction force during rotor rotation through a special blade shape and arrangement, promoting the rapid intake of cool air and the effective exhaust of hot air, achieving high-efficiency heat dissipation. This structural design is particularly suitable for high-power density, long-time continuous operation motor environments, significantly prolonging the service life of the motor and improving operational reliability;

[0012] 2. By welding several fan blade-shaped reinforcing pieces on the front part of the motor front cover, providing first ventilation openings between adjacent fan blade-shaped reinforcing pieces, and opening second ventilation openings on the rear part of the motor rear cover, as well as third ventilation openings on the left and right sides of the motor front cover, full-range air circulation is achieved. This ventilation opening layout effectively solves the common problem of local overheating in traditional motors, as it allows cool air to enter the motor interior from multiple directions, forming a complete air circulation system. The first ventilation openings near the fan blade-shaped reinforcing pieces help to enhance air intake strength; the second ventilation openings on the motor rear cover facilitate the rapid exhaust of heated air; and the third ventilation openings provide an additional air intake and exhaust channel, which is particularly important in cases of motor transverse installation or limited space. This design not only improves the overall heat dissipation performance of the motor, but also reduces mechanical vibration and noise caused by poor airflow, enhancing user experience.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the ordinary skilled in the art without creative labor are within the scope of the present application.

[0022] As Figures 1-6The motor structure shown can reduce temperature and noise, comprising a shell 1, one end of the shell 1 is provided with a widened part 7, one end of the widened part 7 is connected with a motor front cover 2, the front part of the motor front cover 2 is welded with a plurality of blade-shaped reinforcing pieces 18, first air vents 3 are arranged between adjacent blade-shaped reinforcing pieces 18, the inside of the widened part 7 is provided with a horn-shaped wind shield 15, the inside of the horn-shaped wind shield 15 is provided with a mixed blade 14, one end of the shell 1 is connected with a motor rear cover 12.

[0023] The rear part of the motor rear cover 12 is provided with a second air vent 11, the left side and the right side of the motor front cover 2 are respectively provided with third air vents 4.

[0024] The top of the motor front cover 2 is fixedly connected with two connecting blocks 6, mounting holes are arranged on the connecting blocks 6.

[0025] The top of the motor front cover 2 is fixedly connected with a central positioning plate 9, the lower part of the motor front cover 2 is fixedly connected with a heightening plate 8.

[0026] The inside of the shell 1 is provided with a stator and a rotor, the first output shaft 13 of the rotor is in transmission connection with the mixed blade 14, the first output shaft 13 is fixedly connected with a first gear, the first gear is in transmission connection with a second gear 16, the second gear 16 is in transmission connection with a second output shaft 5.

[0027] The motor front cover 2 is fixedly connected with a first sleeve 19 and a second sleeve 17, the second sleeve 17 is connected with an end cover 10 through bolts, the right side of the first sleeve 19 is provided with a notch part.

[0028] Working principle: when in use, the motor starts and provides kinetic energy to the mixed blade 14 through the first output shaft 13. The mixed blade 14 is located inside the horn-shaped wind shield 15, as the rotor rotates, the blade starts to work, generating strong suction force, so that external cold air is sucked into the motor through the first air vent 3. The horn-shaped wind shield 15 cleverly utilizes the principle of aerodynamics, forming a certain negative pressure area on both sides, which not only enhances the air intake efficiency, but also ensures that the airflow can enter the motor more smoothly, reducing the possibility of airflow turbulence.

[0029] The blade-shaped reinforcing pieces on the motor front cover 2 have a dual role in structure: on the one hand, they enhance the mechanical strength of the motor front cover 2, ensuring the stability of the motor under high-speed operation; on the other hand, these reinforcing ribs work together with the first air vent 3 to more freely guide the wind out, guiding and accelerating the airflow, thereby improving the ventilation efficiency of the entire system. Excellent air outlet design not only helps to quickly remove the heat generated during motor operation, achieving better cooling effect, but also reduces the noise caused by airflow friction, providing a quieter working environment for users.

[0030] In addition, the presence of the second vent 11 and the third vent 4 further optimizes the airflow path, forming a complete internal and external circulation system. Hot air is quickly expelled outside the motor through these vents, avoiding the occurrence of localized overheating phenomena, which is essential to maintain the high efficiency of the motor. An effective heat dissipation mechanism not only extends the service life of the motor, but also improves its long-term working reliability.

[0031] In summary, the utility model realizes strong and efficient air circulation through a series of carefully designed structural improvements, such as the widened part 7, the trumpet-shaped wind deflector 15, the hybrid fan blade 14, and the unique vent layout. This design not only significantly reduces the temperature and noise level of the motor, but also greatly improves the overall performance and life of the motor, providing users with a more stable and reliable power solution.
