Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0034] This application provides an installation structure to address the problem of low versatility in the mounting parts for the motor of an air conditioner cross-flow fan. The following description, in conjunction with the accompanying drawings, will illustrate this structure.

[0035] In the embodiments of this application, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the mounting structure includes:

[0036] The base 1 has a mounting cavity 11 for accommodating the motor 3. A first pressing block 12 is protruding from the side wall of the mounting cavity 11 and is positioned near the opening of the mounting cavity 11.

[0037] The pressure cover 2 is used to block the motor 3 from moving upward along the axis of the motor 3. A second pressure block 21 is provided on the periphery of the pressure cover 2.

[0038] The first pressure block 12 is inclined toward the surface of the motor 3, and the second pressure block 21 is inclined away from the surface of the mounting cavity 11. The pressure cover 2 is rotatably embedded in the mounting cavity 11. The second pressure block 21 is located between the first pressure block 12 and the motor 3. Along the circumference of the motor 3, the first pressure block 12 drives the second pressure block 21 to gradually press against the motor 3.

[0039] It should be noted that the pressure cap 2 rotates about the shaft of the motor 3. The surface of the second pressure block 21 facing away from the mounting cavity 11 refers to the surface that mates with the first pressure block 12. When installing the pressure cap 2, the position of the pressure cap 2 must first be adjusted so that the first pressure block 12 and the second pressure block 21 are misaligned. Then, the pressure cap 2 is inserted into the mounting cavity 11 and rotation begins. The surface of the first pressure block 12 facing the motor 3 gradually comes into contact with the surface of the second pressure block 21 facing away from the mounting cavity 11. As the pressure cap 2 gradually penetrates deeper into the mounting cavity 11, the inclined surface on the first pressure block 12 that mates with the second pressure block 21 will drive the second pressure block 21 to gradually approach the motor 3 and eventually press it against the end of the motor 3, completing the installation and fixing of the pressure cap 2. It can be imagined that the surface on the first pressure block 12 that mates with the second pressure block 21 is inclined relative to the end of the motor 3.

[0040] It is understandable that the pressure cover 2 is rotated and fixed by the inclined surfaces on the first pressure block 12 and the second pressure block 21. For different motor models, only the corresponding base 1 and pressure cover 2 need to be replaced, and the motor 3 can be installed and fixed by using the first pressure block 12 on the replaced base 1 and the second pressure block 21 on the pressure cover 2. No additional new parts, such as bolts, are needed to further fix the base 1 and pressure cover 2. In this embodiment, the first pressure block 12 and the second pressure block 21 can be applied to base 1 and pressure cover 2 with various structures, which is more versatile. When replacing, the pressure cover 2 can be removed simply by rotating it in the opposite direction.

[0041] In some embodiments, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the vertical distance between the first pressure block 12 and the motor 3 gradually decreases upward along the circumference of the motor 3, and the surface of the second pressure block 21 facing the motor 3 is in close contact with the surface of the first pressure block 12 away from the mounting cavity 11.

[0042] It should be noted that "the vertical distance between the first pressure block 12 and the motor 3 gradually decreases upward along the circumference of the motor 3" refers to the vertical distance between the surface of the first pressure block 12 facing the motor 3 and the motor 3. The inclination of the surface of the first pressure block 12 facing the motor 3 is consistent with the inclination of the surface of the first pressure block 12 away from the mounting cavity 11, so that the above surfaces achieve a tight fit.

[0043] Understandably, the first pressure block 12 and the second pressure block 21 work closely together to improve the installation stability of the pressure cover 2 and prevent the pressure cover 2 from tilting up.

[0044] In some embodiments, such as Figure 3 As shown, the surface of the first pressure block 12 facing the motor 3 is provided with a limiting protrusion, and the surface of the second pressure block 21 along the radial direction of the pressure cover 2 is provided with a limiting groove 211. The limiting protrusion is used to engage with the limiting groove 211.

[0045] It is understandable that when the surface of the first pressure block 12 and the surface of the second pressure block 21 are properly fitted, the pressure cover 2 is installed and fixed. At the same time, the limiting protrusion is embedded in the limiting groove 211 to limit the pressure cover 2 in the circumferential direction, prevent the pressure cover 2 from rotating in the opposite direction, avoid the pressure cover 2 from loosening or even coming out of the installation cavity 11, and improve the reliability of the pressure cover 2 fixing.

[0046] In some embodiments, such as Figure 3 As shown, multiple first pressing blocks 12 and second pressing blocks 21 are provided in a one-to-one correspondence.

[0047] It is understandable that the one-to-one cooperation of multiple first pressure blocks 12 and multiple second pressure blocks 21 serves to fix multiple positions on the pressure cover 2, balance the force on the pressure cover 2, and prevent the pressure cover 2 from tilting due to concentrated force, so that the pressure cover 2 is more firmly installed in the mounting cavity 11.

[0048] In some embodiments, multiple first pressure blocks 12 are spaced upward along the circumference of the motor 3. Along the direction of the opening of the mounting cavity 11 close to the motor 3, the vertical distance between the multiple first pressure blocks 12 and the motor 3 gradually decreases. The second pressure block 21 moves upward along the circumference of the motor 3 and cooperates with the multiple first pressure blocks 12 in sequence.

[0049] Understandably, as the pressure cap 2 gradually rotates deeper into the mounting cavity 11, the second pressure block 21 sequentially abuts against the surface of each first pressure block 12 facing the motor 3. After passing each first pressure block 12, the pressure cap 2 moves closer to the motor 3 until it is firmly against the end of the motor 3. Furthermore, the second pressure block 21 does not necessarily need to engage with the first pressure block 12 closest to the motor 3 to secure the pressure cap 2. The rotation depth of the pressure cap 2 can be adjusted according to the axial length of the motor 3, providing better versatility for motors 3 that differ only in axial length. It is conceivable that the multiple first pressure blocks 12 form a design similar to rotating steps on the side wall of the mounting cavity 11.

[0050] In some embodiments, such as Figure 4 and Figure 5As shown, the base 1 is provided with a snap-fit ​​arm 13, and the pressure cover 2 is provided with multiple snap-fit ​​slots 22 in the circumferential direction. The second pressure block 21 is located between the multiple snap-fit ​​slots 22 and the motor 3. One end of the snap-fit ​​arm 13 is connected to the opening end of the mounting cavity 11, and the other end of the snap-fit ​​arm 13 is used to snap into any of the snap-fit ​​slots 22.

[0051] It is understandable that after the first pressing block 12 presses the cover 2 against the end of the motor 3, the snap-fit ​​arm 13 is snapped into the corresponding slot 22 to restrict the cover 2 from rotating circumferentially, prevent the cover 2 from rotating in the opposite direction and exiting the mounting cavity 11, and improve the installation stability of the cover 2.

[0052] In some embodiments, such as Figure 5 and Figure 6 As shown, the depth of each slot 22 gradually increases in the counterclockwise direction along the circumference of the pressure cover 2, and the first pressure block 12 drives the second pressure block 21 to gradually press against the motor 3.

[0053] It should be noted that the counterclockwise direction of the pressure cover 2 refers to the counterclockwise direction of the pressure cover 2 when viewed from the opening of the mounting cavity 11 towards the motor 3.

[0054] Understandably, the pressure cap 2 is inserted into the mounting cavity 11 in a counterclockwise direction, so that the first pressure block 12 drives the second pressure block 21 to gradually press against the end of the motor 3. Then, the snap-fit ​​arm 13 is snapped into the corresponding slot 22, completing the fixation of the pressure cap 2. If the pressure cap 2 rotates clockwise at this time, the snap-fit ​​arm 13 is difficult to disengage from the slot 22 due to the greater depth of the slot 22 in the counterclockwise direction along the circumference of the pressure cap 2, thus effectively restricting the rotation of the pressure cap 2. In addition, during the process of the second pressure block 21 gradually pressing against the end of the motor 3, the snap-fit ​​arm 13 undergoes a clockwise relative movement with respect to the pressure cap 2, the depth of the slot 22 gradually decreases, and the bottom wall of the slot 22 drives the snap-fit ​​arm 13 to deform. One end of the snap-fit ​​arm 13 exits from the current slot 22 and is inserted into the adjacent slot 22, avoiding interference with the rotation of the pressure cap 2. When the pressure cap 2 is pressed against the end of the motor 3, one end of the locking arm 13 remains in the current slot 22 to achieve circumferential limiting, and the installation process is completed in one step. When removing the pressure cap 2, the locking arm 13 is pushed outward to disengage from the slot 22, and then the pressure cap 2 is rotated clockwise.

[0055] In some embodiments, such as Figure 5 As shown, the snap-fit ​​arm 13 extends counterclockwise along the circumference of the pressure cap 2.

[0056] Understandably, the bottom wall of the card slot 22 can better drive the deformation of the card arm 13, thereby enabling the card arm 13 to quickly respond to the rotation of the cover 2, exit the current card slot 22 radially upward along the cover 2 and embed into the adjacent card slot 22.

[0057] In some embodiments, such as Figure 4 As shown, the bottom walls and side walls of multiple slots 22 are enclosed to form a sawtooth structure, and the bottom wall of any slot 22 forms a tooth with the side wall of its adjacent slot 22.

[0058] In some embodiments, such as Figure 4 As shown, the inner wall of the mounting cavity 11 is provided with a clearance opening 111. The clearance opening 111 extends upward along the motor 3 axis through the opening end of the mounting cavity 11 and is used to avoid the second pressure block 21.

[0059] Understandably, the second pressure block 21 allows the pressure cap 2 to be embedded in the mounting cavity 11 through the clearance opening 111.

[0060] For example, multiple first pressing blocks 12 and multiple second pressing blocks 21 are provided in a one-to-one correspondence, and multiple clearance openings 111 are provided in a one-to-one correspondence with the second pressing blocks 21.
