Example 1
As shown in fig. 1-2, the present embodiment provides a connection structure for a middle frame and a lower base, which is suitable for connecting a middle frame 1 and a lower base 3 of an air conditioner, and includes a first connection portion 13 disposed at an upper edge 12 of an air outlet of the middle frame 1 and an upper air outlet channel 31 disposed on the lower base 3, where the first connection portion 13 includes a protrusion structure 14, and a top end of the protrusion structure 14 abuts against one end of the upper air outlet channel 31, so that a point and a surface are formed between the middle frame 1 and the lower base 3 and connected in a matching manner.
When the air conditioner is operated, all the components are matched with each other to run, vibration is inevitably generated, and then vibration noise is generated, such as vibration transmission between the middle frame 1 and the lower base 3, and the noise affects user experience. In the existing air conditioner, because the middle frame 1 is a long and wide plastic piece, and because the structural strength of the middle frame 1 at the air outlet 11 is weaker, the middle frame is more easily vibrated in the using process, when the joint of the upper edge 12 of the air outlet of the middle frame 1 and the upper air outlet channel 31 of the lower base 3 is matched by adopting a surface-to-surface gap, the contact area of the middle frame 1 and the lower base 3 is larger, and the friction surface of mutual friction generated by vibration is also larger, so that the air conditioner can generate larger working noise.
In order to effectively reduce the noise generated between the middle frame 1 and the lower base 3, in this embodiment, a connection structure of the middle frame and the lower base is provided, and the first connection portion 13 is disposed at the upper edge 12 of the air outlet of the middle frame 1, and the first connection portion 13 is in contact with the upper air outlet channel 31 of the lower base 3. The first connecting portion 13 includes a protruding structure 14, the protruding structure 14 is formed on one side of the air outlet upper edge 12 of the middle frame 1 facing the inside of the middle frame 1, so that in an assembled state, a top end of the protruding structure 14 abuts against one end of the upper air outlet channel 31 of the lower base 3, which is close to the middle frame 1. The protruding structure 14 may be disposed at a position where vibration is strong between the air outlet 11 of the middle frame 1 and the lower base 3. As shown in fig. 2, the top end of the protruding structure 14 is the end far away from the upper edge 12 of the air outlet, in the assembled state of the middle frame 1 and the lower base 3, the free end of the upper air outlet channel 31 contacts with the end of the protruding structure 14 far away from the upper edge 12 of the air outlet, and under the action of external force, the upper air outlet channel 31 and the protruding structure 14 are squeezed, so that the top end of the protruding structure 14 and the end of the upper air outlet channel 31 close to the middle frame 1 are abutted together.
Preferably, the number of the first connecting portions 13 is plural, that is, the number of the protruding structures 14 is plural, and the plural first connecting portions 13 are disposed along the length direction (i.e., the left and right direction as shown in fig. 4) of the air outlet 11 of the middle frame 1, so as to avoid that the connecting strength between the upper edge 12 of the air outlet of the middle frame 1 and the lower base 3 is insufficient due to the too small contact area therebetween. Through evenly setting up a plurality of protruding structures 14 along the inside one side of air outlet upper edge 12 near center 1, not only can improve noise reduction, and can improve the leakproofness between center 1 and lower base 3.
Preferably, the protruding structure 14 is cylindrical, conical or truncated cone-shaped, and preferably, the protruding structure 14 is conical, that is, the protruding structure 14 has a smooth arc top, so that the contact area between the middle frame 1 and the lower base 3 can be further reduced on the basis of ensuring the connection strength of the middle frame and the lower base 3, and the noise generated by the middle frame 1 and the lower base 3 in the working process can be further reduced. In addition, when the upper edge 12 of the air outlet of the middle frame 1 abuts against the upper air outlet channel 31 of the lower base 3, the load is concentrated at the position of the protruding structure 14, so that the protruding structure 14 needs to meet a certain strength requirement, the shape of the protruding structure 14 can be determined according to the actual stress condition, and the upper edge 12 of the air outlet of the middle frame 1 and the upper air outlet channel 31 of the lower base 3 are connected in a point-surface mode.
In the connecting structure of the middle frame and the lower base provided by this embodiment, the first connecting portion 13 is arranged at the upper edge 12 of the air outlet of the middle frame 1, so that the surface-to-surface connection between the upper edge 12 of the air outlet of the middle frame 1 and the lower base 3 is optimized as point-to-surface connection; the contact area between the upper edge 12 of the air outlet of the middle frame 1 and the lower base 3 is greatly reduced, so that the vibration transmission area between the middle frame 1 and the lower base 3 is reduced, the noise generated by the air conditioner in the working process is effectively reduced, and the user experience is improved.
