[0064] It should be noted that this embodiment takes three damping protrusions 401 as an example. Of course, the number of the damping protrusions 401 can also be selected as other values according to the actual situation, which is not limited here.

[0070] Among them, to ensure that the first vibration damping pad 30 can be stably installed on the bracket 10, referring to the attached Figure 3 and 6 , a cylindrical second limiting member 301 is provided in the middle of the bottom wall of the first vibration damping pad 30, and the bracket 10 is provided with a second limiting through hole 101 corresponding to the second limiting member 301;
[0071] Any one of the second limiting members 301 can be inserted into the corresponding second limiting through hole 101 in a matching manner.
[0072] It should be noted that only one second limiting member 301 is provided in the middle of the bottom wall of the first vibration damping pad 30 in this embodiment. And the value range of the thickness T1 of the edge of the first vibration damping pad 30 is [5 mm, 10 mm], and the thickness T1 of the edge of the first vibration damping pad 30 is equivalent to the height of the first vibration damping pad 30 excluding the second limiting member 301. Of course, the thickness T1 of the edge of the first vibration damping pad 30 can also be selected as other values according to the actual situation, which is not limited here.
[0073] Among them, referring to the attached Figures 3-4 and the attached Figure 6 , a circular first through hole 302 is provided in the middle of the first vibration damping pad 30, a circular second through hole 403 is provided in the middle of the second vibration damping pad 40, a third through hole 202 is provided on the top wall of the bracket 20 corresponding to the first limiting through hole 201, a limiting bolt 50 is provided in a matching manner between the first through hole 302 and the second through hole 403, and the limiting bolt 50 can sequentially pass through the first through hole 302, the second through hole 403 and the third through hole 202.
[0074] In this way, the second limiting member 301 of the first vibration damping pad 30 is inserted into the second limiting through hole 101 of the bracket 10 in a matching manner, the first limiting member 402 of the second vibration damping pad 40 is inserted into the first limiting through hole 201 of the bracket 20 in a matching manner, and then the limiting bolt 50 sequentially passes through the first through hole 302, the second through hole 403 and the third through hole 202, that is, after the limiting bolt 50 sequentially passes through the first vibration damping pad 30, the bracket 10, the second vibration damping pad 40, and then is connected to the bracket 20, so as to fix the first vibration damping pad 30, the bracket 10 and the second vibration damping pad 40 on the bracket 20, respectively, so as to improve the supportability, structural stability and structural reliability of the vibration damping structure.
[0075] It should be noted that the first through hole 302 also penetrates through the second limiting member 301, and the depth of the second through hole 403 is also equivalent to the thickness T3 of the middle part of the second damping pad 40; and the first limiting through hole 201 is circumferentially arranged around the third through hole 202 as the center.

[0077] And an external thread is provided on the outer surface of the limiting bolt 50 located below the limiting step 501 to facilitate the connection of matching nuts and bolts.
[0078] In this way, when the limiting bolt 50 passes through the third through hole 202, the limiting step 501 abuts against the top wall of the bracket 20, so that the limiting bolt 50 located above the limiting step 501 cannot be inserted into the third through hole 202, thereby restricting the depth of the limiting bolt 50 screwed into the bracket 20 to avoid excessive compression of the second damping pad 40 and thus affecting the damping performance.
[0079] Among them, referring to the attached Figure 7 , to ensure the damping effect and stability of the damping structure, it is necessary to limit the length L1 of the limiting bolt 50 located above the limiting step 501. Therefore, the value range of L1 is:

Moreover, compared with the existing damping structure that needs to install the damping rubber pad 400 separately in sequence, the present utility model can reduce the assembly tolerance during the installation of the first damping pad 30 and the second damping pad 40, improve the structural reliability, and further improve the consistency of the vibration noise during the operation of the water pump, effectively improving the working performance and user experience of the air conditioner. And compared with the existing damping structure where the damping rubber pad 400 needs to be connected to the bracket by a matching screw, and this process needs to be repeated three times, while the damping structure of the present utility model only needs one limit screw 50 to connect and fix, thus improving the production and assembly efficiency.
[0087] Among them, with reference to the attached Figure 9 , the shape of the bracket 10 is preferably L-shaped, and a plurality of mounting through holes 102 are provided on the side wall of the bracket 10.

The drawings give the preferred embodiments of the present utility model, but do not limit the patent scope of the present utility model. The present utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.
