The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The specific structure of the motor assembly 100 according to the embodiment of the present invention is described below with reference to fig. 1 to 3.
As shown in fig. 1-2, a motor assembly 100 according to an embodiment of the present invention includes a mounting base 10, a motor 20, and a wind wheel 30. The installation base 10 is provided with a first clamping piece 11, the motor 20 is provided with a motor shaft 21, the motor 20 is provided with a second clamping piece 22, the motor 20 is arranged on the installation base 10, the second clamping piece 22 is in clamping connection with the first clamping piece 11, and the wind wheel 30 is connected to the motor shaft 21. A damping member 12 is provided between the surfaces of the first fastening member 11 and the second fastening member 22 that are in contact.
It can be appreciated that the motor 20 is connected with the mounting base 10 through a buckle, the connecting structure is simple, and the motor 20 is mounted without other tools, so that the assembly efficiency of the motor 20 is improved. In addition, the surface that the second fastening piece 22 on the motor 20 contacts with the first fastening piece 11 on the installation base 10 is provided with the damping piece 12, the damping piece 12 can completely isolate the motor 20 from the installation support, the full damping installation between the motor 20 and the installation is realized, the resonance between the motor 20 and the installation base 10 is avoided, the vibration transmitted to the installation base 10 and the wind wheel 30 by the motor 20 is effectively isolated, and the working noise of the motor assembly 100 is reduced.
According to the motor assembly 100 of the embodiment of the invention, as the motor 20 is in snap connection with the mounting seat, and the damping piece 12 is arranged on the surface of the second snap fastener 22 on the motor 20, which is contacted with the first snap fastener 11 on the mounting base 10, the purposes of simplifying the connection structure, reducing the production cost, improving the assembly efficiency of the motor 20, effectively isolating the vibration of the motor 20 transmitted to the mounting base 10 and reducing the working noise of the motor assembly 100 are achieved.
In some embodiments, the damping member 12 is a damping coating or a damping cushion.
Alternatively, when the damping member 12 is a damping rubber pad, the damping rubber pad is adhered to the first fastening member 11 or the second fastening member 22. Therefore, the phenomenon that the vibration isolation effect is reduced due to the falling of the damping rubber pad during installation can be prevented.
Alternatively, when the damper 12 is a damper coating, the damper coating may be formed on the inner peripheral wall of the first seizing means 11 or on the outer peripheral wall of the second seizing means 22. The damping coating is arranged to isolate vibration, so that the processing efficiency is very high.
In some embodiments, as shown in fig. 1, the bottom of the motor 20 is stopped on the mounting base 10, the second fastening members 22 are disposed on the peripheral wall of the motor 20 and are a plurality of circumferentially disposed, and the mounting base 10 is provided with a plurality of first fastening members 11 in a one-to-one correspondence around the motor 20. Such a design may promote mounting stability between the mounting base 10 and the motor 20. In addition, each of the snap structures is provided with a damping member 12, thereby enhancing vibration isolation between the mounting base 10 and the motor 20.
Specifically, as shown in fig. 2, the inner side of each first fastening member 11 facing the motor 20 is provided with a fastening groove 111, the fastening grooves 111 of the plurality of first fastening members 11 are open on the same side in the clockwise direction, and each second fastening member 22 is screwed into the corresponding fastening groove 111.
It can be understood that when the motor 20 is installed, only the second fastening member 22 is required to be aligned to the fastening groove 111, and then the motor 20 is rotated to enable the second fastening member 22 to be screwed into the corresponding fastening groove 111.
Specifically, each card slot 111 has only one opening in the clockwise direction. It will be appreciated that if the slot 111 has two openings, the motor 20 may be excessively rotated when the motor 20 is mounted, i.e., the second fastening member 22 is rotated out of the slot 111 due to the excessive rotation when the motor is mounted. Therefore, each of the clamping grooves 111 has only one opening in the clockwise direction, and the phenomenon of over-rotation of the motor 20 can be avoided by using the closed structure of the other side, so that the connection reliability between the motor 20 and the mounting base 10 is improved.
In some alternative embodiments, as shown in fig. 3, each second fastening member 22 includes a self-locking piece 221, and a surface of the self-locking piece 221 away from the mounting base 10 forms a self-locking surface, and the distance between the self-locking surface and the mounting base 10 gradually decreases in a direction in which the second fastening member 22 is screwed into the corresponding fastening groove 111.
It will be appreciated that, during the screwing of the self-locking block 221 into the corresponding clamping groove 111, the distance between the self-locking surface and the mounting base 10 in the screwing direction of the motor 20 is gradually reduced, that is, the self-locking block 221 and the clamping groove 111 have a height difference in the direction of the motor shaft 21. Therefore, in the screwing process, the self-locking surface of the self-locking block 221 rotates more and more tightly with the wall surface of the clamping groove 111, the self-locking block 221 is deformed by the pressure from the wall surface of the clamping groove 111, and when the self-locking block 221 rotates in place, the self-locking block 221 is locked in the buckle, so as to prevent the second buckle 22 from sliding towards the direction of screwing out of the clamping groove 111.
Specifically, the self-locking block 221 is formed in an arc-shaped bar shape, and the self-locking block 221 is connected to the outer circumferential wall of the motor 20 only at the end remote from the mounting base 10.
It will be appreciated that, as described above, during the screwing process, the second clasp 22 will come from the pressure of the wall of the slot 111. If the second fastening member 22 is all connected to the outer peripheral wall of the motor 20, the screwing resistance is very high due to the deformation of the second fastening member 22 during screwing, which makes the installation of the motor 20 very laborious. Therefore, the self-locking block 221 is designed to have a cantilever structure connected with the outer peripheral wall of the motor 20 only at the end far from the mounting base 10, so that on the premise that the self-locking block 221 can realize the self-locking function, the screwing resistance is reduced, and a user can mount the motor 20 in a more labor-saving manner.
More specifically, as shown in fig. 3, each second fastening member 22 further includes a guide block 222, and the guide block 222 is located downstream from the locking block 221 in the direction in which the second fastening member 22 is screwed into the corresponding fastening groove 111. The guide block 222 can play a role in rotating the motor 20, and facilitates installation of the motor 20. That is, when the first fastening piece 22 is engaged with the first fastening piece 11, the guide block 222 is first screwed into the fastening groove 111, and the self-locking block 221 starts to be screwed into the fastening groove 111 when the screwing is continued.
In some embodiments, a damping structure 23 is provided between the motor shaft 21 and the wind wheel 30. Thus, the damping installation between the motor 20 and the wind wheel 30 can be realized, the resonance phenomenon of the motor 20 and the wind wheel 30 is avoided, and the working noise of the motor 20 is reduced.
Alternatively, the damping structure 23 is formed by a damping coating applied to the motor shaft 21 where the rotor 30 is mounted.
Alternatively, as shown in fig. 3, the damping structure 23 is formed as a damping spacer and is mounted between the motor shaft 21 and the wind wheel 30.

The wind wheel 30 is connected to the motor shaft 21, and a damping structure 23 is installed between the wind wheel 30 and the motor shaft 21. A damping member 12 is provided between the surfaces of the first fastening member 11 and the second fastening member 22 that are in contact.
As shown in fig. 2, the inner side of each first fastening member 11 facing the motor 20 is provided with a fastening groove 111, the fastening grooves 111 of the plurality of first fastening members 11 are open on the same side in the clockwise direction, and only one opening is provided, and each second fastening member 22 can be screwed into the corresponding fastening groove 111.
