Referring to fig. 1 and 2, a motor mounting structure 100 according to an embodiment of the present invention is used for an embedded air conditioner, and the motor mounting structure 100 includes a base plate 10, a motor base 20, and a shock absorbing member 30.

The chassis 10 is for mounting to a wall or ceiling. The motor mount 20 is disposed on the chassis 10 through a shock absorbing member 30. The motor base 20 and the wall are respectively disposed on two opposite sides of the chassis 10. Alternatively, the motor base 20 and the ceiling are respectively disposed on two opposite sides of the chassis 10. The motor mount 20 is used to mount the motor 40. The shock absorbing member 30 serves to absorb shock generated from the motor 40.

In the motor mounting structure 100 according to the embodiment of the present invention, the shock absorbing element 30 can absorb the shock generated by the motor 40, so that the shock generated by the motor 40 can be prevented from being transmitted through the chassis 10, the generation of noise is reduced, and the user experience is improved.

Specifically, the embedded air conditioner includes a ceiling unit, and generally, the ceiling unit is installed on a ceiling, and when the ceiling unit is operated, the heat-exchanged wind generated by the ceiling unit is diffused from the ceiling to a floor and an indoor space, thereby achieving an effect of adjusting an indoor temperature.

Referring to fig. 3, the chassis 10 includes a bottom plate 11 and a sidewall 12. The base plate 11 is circular. The base plate 11 is used for mounting to a wall or a ceiling. The side wall 12 extends downward from the periphery of the bottom plate 11. The base plate 11 is formed with a radial reinforcing structure 13 connected to the center 111 of the base plate 11. The reinforcing structure 13 may increase the rigidity of the chassis 10, thereby reducing the vibration of the chassis 10 to reduce the occurrence of the jolts.

In the present embodiment, the reinforcing structure 13 is a reinforcing rib having a bar shape. Of course, in other embodiments, the reinforcing structure 13 may be a reinforcing structure such as a reinforcing plate having an uneven surface.

The bottom plate 11 is a hollow structure, so that the quality of the bottom plate 11 can be reduced while the bottom plate 11 forms the reinforcing structure 13 to ensure the strength of the bottom plate 11.

The sidewall 12 may be formed with a plurality of through holes through which the housing of the built-in air conditioner may be assembled to the base plate 10. It can be understood that other parts such as a heat exchanger and a wind wheel are arranged in the shell of the embedded air conditioner.

In the present embodiment, the plurality of side walls 12 are spaced apart from each other in the circumferential direction of the bottom plate 11. Of course, in other embodiments, the side wall 12 may extend continuously around the circumferential direction of the bottom plate 11.

The motor mount 20 is disposed at the center 111 of the base plate 11. Since the motor 40 is mounted on the motor mount 20, the motor 40 is located at the center 111 of the base plate 11. In the present embodiment, since the bottom plate 11 has a circular shape, the center 111 of the bottom plate 11 is a portion near the center of the bottom plate 11. In other embodiments, when the bottom plate 11 has a shape other than a circular shape, the center 111 of the bottom plate 11 is an area near the geometric center of the bottom plate 11 or an area near the center of gravity of the bottom plate 11.

Specifically, the motor mount 20 has a circular ring shape. In addition, the motor base 20 may have a sheet shape. The motor base 20 includes a motor connecting portion 21, and the motor connecting portion 21 is used for mounting the motor 40. The motor connecting portion 21 is opened with a motor mounting hole 211. In this embodiment, the number of the motor mounting holes 211 is three, and the three motor mounting holes 211 are uniformly spaced around the circumferential direction of the motor base 20. Of course, in other embodiments, the number of the motor mounting holes 211 may be four or five, among other numbers. A space 23 for avoiding the fastener is formed between the motor connecting portion 21 and the base plate 11.

the motor base 20 is further provided with a plurality of through holes 22 for fixing the damping element 30, and the through holes 22 and the motor mounting holes 211 are sequentially arranged at intervals in an alternating manner around the circumferential direction of the motor base 20.

The number of the shock absorbing members 30 is plural, and the plurality of shock absorbing members 30 are arranged at intervals around the circumferential direction of the motor base 20. It will be appreciated that the number of dampening members 30 is the same as the number of perforations 22, all three. It is understood that in other embodiments, the number of shock absorbing elements 30 may be set according to actual circumstances.

the shock-absorbing member 30 may be made of an elastic material, such as rubber, foam, or the like, so that the shock-absorbing member 30 has elasticity to absorb shock generated from the motor 40.

The shock-absorbing member 30 includes a first shock-absorbing portion 31 and a second shock-absorbing portion 32. The first damper portion 31 is disposed between the chassis 10 and the motor base 20. The first damper 31 abuts against the chassis 10 and the motor base 20. The first damping portion 31 is in a truncated cone shape, and two end surfaces of the first damping portion 31 are distributed to abut against the chassis 10 and the motor base 20.

The second damper element 30 is inserted into the motor base 20 and connected to the first damper portion 31. Specifically, the second damper portion 32 passes through the through hole 22. The connection between the second damping portion 32 and the first damping portion 31 is formed with a limiting structure 33 for limiting the movement of the motor base 20 relative to the damping element 30. In this embodiment, the limiting structure 33 is an annular groove, and the annular groove is clamped in the through hole 22 so as to limit the movement of the damping element 30 relative to the motor base 20.

referring to fig. 2 and 3 again, the motor mounting structure 100 further includes a first fastener 50, a second fastener 60, a motor 40, and a third fastener 70.

The first fastening member 50 is fixed to the chassis 10, and the second fastening member 60 is detachably coupled to the first fastening member 50. First fastener 50 cooperates with second fastener 60 to secure shock absorbing element 30 and motor mount 20 to chassis 10.

In the present embodiment, the first fastening member 50 is a stud fixed to the chassis 10. The axial direction of the stud is arranged substantially perpendicular to the chassis 10. The shock absorbing element 30 and the motor base 20 are sleeved on the stud, and the second fastening member 60 is a nut connected with the stud in a matching manner. Of course, in other embodiments, the first fastening member 50 may be a nut fixed on the chassis 10, and the second fastening member 60 may be a stud penetrating the motor base 20 and the damping element 30.

The motor 40 is mounted on the motor mount 20. The motor 40 and the chassis 10 are respectively disposed on two opposite sides of the motor base 20, that is, the motor 40 and the chassis 10 are not in contact. This prevents the vibration generated by the motor 40 from being directly transmitted to the chassis 10.

the motor 40 includes a body 41 and a mounting ear 42. The body 41 is cylindrical. Mounting ears 42 extend radially outward from body 41 along body 41. Specifically, the body 41 includes a top 411 and a bottom 412. The bottom 412 is disposed opposite the top 411. The motor shaft 43 of the motor 40 extends from the top portion 411 and the mounting ears 42 are disposed at the bottom portion 412.

The motor 40 is fixedly mounted on the motor base 20 by a third fastener 70 passing through the mounting lug 42. The third fastener 70 extends from the mounting ear 42 into the space 23 to avoid screw contact with the chassis 10. The third fastening member 70 is, for example, a screw, and a screw hole is formed in the motor base 20, and the motor 40 is screwed into the screw hole by the screw, so as to be fixed to the motor base 20.

When the structure of the motor 40 is assembled, the damping element 30 may be first clamped in the through hole 22 to fix the damping element 30 on the motor base 20, then the motor base 20 with the damping element 30 is collectively sleeved on the second fastening member 60 (stud), the third fastening member 70 (nut) is used to cooperate with the second fastening member 60 to fix the motor base 20 and the damping element 30 on the chassis 10, and then the motor 40 is fixed on the motor base 20 through the third fastening member 70, so as to assemble the structure of the motor 40.

The air duct comprises an air inlet and an air outlet. The heat exchanger is arranged in the air duct. The fan is arranged in the air duct and is used for establishing air flow from the air inlet to the air outlet. The fan includes a motor 40.

In the embedded air conditioner 200 according to the embodiment of the present invention, since the damping element 30 can absorb the vibration generated by the motor 40, the vibration generated by the motor 40 can be prevented from being transmitted through the chassis 10, the generation of noise is reduced, and the user experience is improved.
