[0007] Furthermore, the motor pressure plate adjustment portion is detachably connected to the motor pressure plate main body portion.

[0008] Furthermore, the motor pressure plate adjustment part includes a stop structure and a mounting structure, wherein the stop structure extends toward the accommodating space and is used to stop and limit the end of the motor; one end of the mounting structure is connected to the stop structure, and the other end of the mounting structure is detachably connected to the motor pressure plate main body. When the mounting structure is connected to the motor pressure plate main body, the stop structure stops and limits the end of the motor, and when the mounting structure is separated from the motor pressure plate main body, the stop structure releases the end stop limit on the motor.

[0009] Furthermore, the main body of the motor pressure plate has a mating structure that cooperates with the mounting structure, the mating structure and the mounting structure are concave-convex mating, and at least one of the mating structure and the mounting structure extends along the circumference of the motor, and at least one of the mating structure and the mounting structure is multiple and arranged along the axial direction of the motor.

[0011] Furthermore, a surface of one side of the mounting plate facing the main body of the motor pressure plate is an arc-shaped surface, and is adapted to the surface in contact with the main body of the motor pressure plate.

[0012] Furthermore, the main body of the motor pressure plate has a limiting groove that cooperates with the first rib. There are multiple limiting grooves that are arranged in sequence along the axial direction of the motor. The first rib selectively extends into one of the multiple limiting grooves to adjust the installation position relationship between the motor pressure plate adjustment part and the main body of the motor pressure plate in the axial direction of the motor.

[0013] Furthermore, the limiting groove is inclined in a direction away from the stop structure along the entry direction of the first rib.

[0014] Furthermore, the motor limiting device includes a connecting portion, at least a portion of the connecting portion is connected to the motor pressure plate main body, and at least another portion of the connecting portion is connected to an end of the motor pressure plate adjusting portion away from the motor pressure plate main body.

[0020] Furthermore, the motor pressure plate adjustment portion has a slot for cooperating with the protrusion of the rubber ring of the motor; and / or, the motor pressure plate adjustment portion has at least one heat dissipation hole.

[0021] Furthermore, a rubber ring is respectively provided on the shaft and end of the motor. When the motor pressure plate main body of the motor limiting device is covered in the accommodating space of the bottom shell, the motor pressure plate main body and the bottom shell form a rubber ring limiting hole on the shaft side of the motor, so that the rubber ring located on the shaft side of the motor is limited at the rubber ring limiting hole. The outer peripheral side of the rubber ring located on the end side of the motor has a protrusion, and the motor pressure plate adjustment part has a slot for cooperating with the protrusion of the rubber ring of the motor.

[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] In order to solve the problem in the prior art that the motor pressure plate cannot be adapted to different models, the present invention provides a motor limiting device and a heat exchange device, wherein the heat exchange device includes a bottom shell 200, a motor limiting device 300 and a motor 100, and the motor limiting device 300 is the motor limiting device 300 described above and below; the motor 100 is arranged in the accommodating space of the motor limiting device 300.

[0045] like Figures 1 to 12 As shown, the motor limiting device 300 includes a motor pressure plate main body 10 and a motor pressure plate adjusting part 20, wherein the motor pressure plate main body 10 is used to be installed at the position to be installed and form an accommodating space with the structural parts at the position to be installed; the motor pressure plate adjusting part 20 is movably connected to the motor pressure plate main body 10, so as to adjust the installation position relationship between the motor pressure plate adjusting part 20 and the motor pressure plate main body 10 on the motor shaft 101 upward, so as to be used for adapting the model of the motor 100.

[0046] By applying the technical solution of the present invention, the motor limiting device 300 is set to a structural form including a motor pressure plate main body 10 and a motor pressure plate adjusting part 20. At the same time, the motor pressure plate main body 10 and the structural parts at the installation position form an accommodating space to provide installation space for the motor 100. In addition, by setting the motor pressure plate adjusting part 20 and the motor pressure plate main body 10 to a movable connection structural form, it is ensured that the motor pressure plate adjusting part 20 and the motor pressure plate main body 10 can be relatively adjusted. That is to say, by adjusting the positional relationship between the motor pressure plate adjusting part 20 and the motor pressure plate main body 10, the volume of the accommodating space is changed, ensuring that the accommodating space can be adapted to motors 100 of different models, without the need to develop a new motor limiting device 300, thereby reducing economic costs.

[0047] like Figures 1 to 3As shown, the motor pressure plate main body 10 has a cavity structure, which is at least a portion of the accommodating space. At least a portion of the motor pressure plate adjustment portion 20 extends into the cavity structure and contacts the cavity wall of the cavity structure, and at least a section of the cavity wall is a curved surface segment. In this way, the motor pressure plate main body 10 has a cavity structure, and at least a section of the cavity wall is a curved surface segment, providing an accommodating space for the installation of the motor 100. At least a portion of the motor pressure plate adjustment portion 20 extends into the cavity structure, so that the motor pressure plate adjustment portion 20 contacts the motor 100.

[0048] like Figure 10 and Figure 11 As shown, the motor pressure plate adjusting portion 20 is rotatably connected to the motor pressure plate main body 10. In this way, the motor pressure plate adjusting portion 20 can rotate within the cavity structure of the motor pressure plate main body 10, making it easy to adjust the positional relationship between the motor pressure plate adjusting portion 20 and the motor pressure plate main body 10 according to different models of motors 100. Figure 10 The arrow A in the figure indicates the direction in which the motor pressure plate adjusting portion 20 is rotated out. Figure 11 The arrow B in FIG. 1 represents the screwing direction of the motor pressure plate adjusting portion 20 .

[0049] Furthermore, the motor pressure plate adjusting portion 20 is detachably connected to the motor pressure plate main body 10. In this way, the motor pressure plate adjusting portion 20 is detachably connected to the motor pressure plate main body 10, which facilitates the installation and removal of the motor 100.

[0050] like Figure 1 、 Figure 2 and Figure 4 As shown, the motor pressure plate adjustment portion 20 includes a stop structure 21 and a mounting structure 22, wherein the stop structure 21 extends toward the accommodation space and is used to stop and limit the end of the motor 100; one end of the mounting structure 22 is connected to the stop structure 21, and the other end of the mounting structure 22 is detachably connected to the motor pressure plate main body 10. When the mounting structure 22 is connected to the motor pressure plate main body 10, the stop structure 21 stops and limits the end of the motor 100. When the mounting structure 22 is separated from the motor pressure plate main body 10, the stop structure 21 releases the end stop limit on the motor 100. In this way, the stop structure 21 limits the motor 100 and prevents the motor 100 from moving axially. The mounting structure 22 is connected to the motor pressure plate main body 10, and the motor pressure plate adjustment portion 20 is installed on the motor pressure plate main body 10. The mounting structure 22 is detachably connected to the motor pressure plate main body 10, which facilitates the installation and removal of the motor 100.

[0051] Furthermore, the motor pressure plate main body 10 has a mating structure that mates with the mounting structure 22. The mating structure and the mounting structure 22 have a concave-convex fit, and at least one of the mating structure and the mounting structure 22 extends along the circumference of the motor 100. There are multiple mating structures and at least one of the mounting structures 22 arranged along the axial direction of the motor 100. In this way, the concave-convex fit between the mating structure and the mounting structure 22 increases the reliability of the connection between the two.

[0052] like Figure 4 As shown, the mounting structure 22 includes a mounting plate 221 and a first rib 222. One end of the mounting plate 221 is connected to the stop structure 21; the first rib 222 is located at the end of the mounting plate 221 away from the stop structure 21. Thus, when the motor pressure plate adjustment portion 20 is mounted on the motor pressure plate main body 10, the end of the mounting plate 221 with the first rib 222 extends into the cavity structure, enhancing the reliability of the connection. The end of the mounting plate 221 connected to the stop structure 21 remains outside the cavity structure, acting as a stop for the motor 100.

[0053] It should be noted that, in the present application, the surface of the mounting plate 221 facing the motor pressure plate main body 10 is an arcuate surface, and is adapted to the surface in contact with the motor pressure plate main body 10. In this way, the surface of the mounting plate 221 facing the motor pressure plate main body 10 is an arcuate surface, which is adapted to the surface in contact with the motor pressure plate main body 10 and is also adapted to the outer peripheral surface of the motor 100, making it easier for the motor 100 to enter the motor pressure plate adjustment portion 20.

[0054] like Figure 3 and Figure 4 As shown, the motor pressure plate adjustment portion 20 has a limiting groove 13 that cooperates with the first rib 222. There are multiple limiting grooves 13 arranged in sequence along the axial direction of the motor 100. The first rib 222 selectively extends into one of the multiple limiting grooves 13 to adjust the installation position relationship between the motor pressure plate adjustment portion 20 and the motor pressure plate main body 10 in the axial direction of the motor 100. In this way, there are multiple limiting grooves 13 arranged in sequence along the axial direction of the motor 100. The motor pressure plate adjustment portion 20 can extend the first rib 222 into the appropriate limiting groove 13 according to the axial size of the motor 100, ensuring a close contact between the stop structure 21 and the motor 100, thereby increasing the reliability of the connection between the motor pressure plate adjustment portion 20 and the motor 100, and preventing the motor 100 from shaking during operation, thereby increasing the safety of the motor 100.

[0055] It should be noted that in the present application, the limiting groove 13 is tilted in the direction away from the stop structure 21 along the entry direction of the first rib 222. In this way, as the first rib 222 is gradually screwed into the limiting groove 13, the fit between the first rib 222 and the limiting groove 13 is ensured to be increasingly tight, thereby ensuring the stability of the fit between the two.

[0056] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the motor limiting device 300 includes a connecting portion 30, at least a portion of which is connected to the motor pressure plate main body 10, and at least another portion of the connecting portion 30 is connected to an end of the motor pressure plate adjustment portion 20 away from the motor pressure plate main body 10. In this way, the motor pressure plate main body 10 and the motor pressure plate adjustment portion 20 are connected via the connecting portion 30, thereby improving the reliability of the connection between the motor pressure plate main body 10 and the motor pressure plate adjustment portion 20.

[0057] Optionally, the connecting portion 30 is slidably connected to the motor pressure plate main body 10 ; and / or, the connecting portion 30 is rotationally connected to the motor pressure plate adjustment portion 20 .

[0058] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the connecting portion 30 includes a support structure 31 and an extension arm 32. The support structure 31 has at least one arcuate segment on its circumference, and at least a portion of the motor pressure plate adjustment portion 20 has a concave-convex fit with the arcuate segment. One end of the extension arm 32 is connected to the support structure 31, and the other end of the extension arm 32 is slidably connected to the motor pressure plate main body 10. In this way, the support structure 31 and the motor pressure plate adjustment portion 20 have a concave-convex fit, and the extension arm 32 connects the support structure 31 to the motor pressure plate main body 10, and further connects the motor pressure plate adjustment portion 20 to the motor pressure plate main body 10, thereby increasing the reliability of the connection between the motor pressure plate main body 10 and the motor pressure plate adjustment portion 20.

[0059] like Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As shown, the end of the extension arm 32 away from the support structure 31 has an opening 321, and the motor pressure plate main body 10 has a hanging post 11 extending along the axial direction of the motor 100 for cooperating with the opening 321. In this way, the opening 321 of the extension arm 32 passes through the hanging post 11, allowing the extension arm 32 to slide on the hanging post 11 along the axial direction of the motor 100, facilitating adjustment of the position between the connecting portion 30 and the motor pressure plate main body 10.

[0060] like Figure 1 、 Figure 2 and Figure 9 As shown, the motor pressure plate main body 10 further includes a stopper 12, which is detachably mounted on the protruding end of the mounting post 11 to stop the extension arm 32. Thus, after the opening 321 of the extension arm 32 passes through the mounting post 11, the stopper 12 is mounted on the mounting post 11 to stop the extension arm 32, thereby increasing the reliability of the connection between the extension arm 32 and the motor pressure plate main body 10.

[0061] like Figure 1 、 Figure 2 and Figure 4 As shown, the motor pressure plate adjustment portion 20 has an arc-shaped baffle on the side closest to the motor shaft 101 of the motor 100. A second rib 211 is disposed on the inner side of the arc-shaped baffle. The arc-shaped segment extends around the circumference of the support structure 31 and defines an annular groove 311. The second rib 211 is embedded in the annular groove 311. Thus, by embedding the second rib 211 in the annular groove 311, the motor pressure plate adjustment portion 20 is restrained in the annular groove 311. Simultaneously, the force directed from the support structure 31 in the direction of the mounting post 11 prevents the motor pressure plate adjustment portion 20 from moving in either the axial direction of the motor 100 or in a direction perpendicular to the axis of the motor 100, thereby increasing the reliability of the motor 100 installation.

[0062] It should be noted that, in the present application, the second rib 211 is embedded in the annular groove 311 , and the second rib 211 and the annular groove 311 can rotate relative to each other.

[0063] It should be noted that, in the present application, a stopper 3111 is provided in the annular groove 311 , and when the second rib 211 rotates to the limit position, the stopper 3111 blocks the second rib 211 from rotating.

[0064] like Figure 4 、 Figure 7 and Figure 8 As shown, the motor pressure plate adjustment portion 20 has a slot 212 for engaging with the protrusion 1021 of the rubber ring 102 of the motor 100; and / or, the motor pressure plate adjustment portion 20 has at least one heat dissipation hole 213. Thus, the protrusion 1021 of the rubber ring 102 of the motor 100 is installed in the slot 212, which improves the reliability of the connection between the motor pressure plate adjustment portion 20 and the motor 100. The motor pressure plate adjustment portion 20 has at least one heat dissipation hole 213 to prevent insufficient heat dissipation during operation of the motor 100, which may cause equipment damage.

[0065] like Figure 7 and Figure 8As shown, a rubber ring 102 is respectively provided on the shaft and end of the motor 100. When the motor pressure plate main body 10 of the motor limiting device 300 is covered in the accommodating space of the bottom shell 200, the motor pressure plate main body 10 and the bottom shell 200 form a rubber ring limiting hole on the shaft side of the motor 100, so that the rubber ring 102 located on the shaft side of the motor 100 is limited at the rubber ring limiting hole, and the outer peripheral side of the rubber ring 102 located on the end side of the motor 100 has a protrusion 1021, and the motor pressure plate adjustment part 20 has a card groove 212 for cooperating with the protrusion 1021 of the rubber ring 102 of the motor 100. In this way, the rubber ring 102 is set on the shaft of the motor 100, and the rubber ring 102 is set in the rubber ring limiting hole. The protrusion 1021 of the rubber ring 102 at the end of the motor 100 cooperates with the slot 212, so that when the motor 100 is working, the rubber rings 102 at both ends can reduce vibration and reduce noise.

[0066] It should be noted that an embodiment of the present application is as follows:

[0067] like Figure 9 As shown, the assembly sequence of the motor pressure plate main body 10 is as follows:

[0068] First, align the first rib 222 of the motor pressure plate adjusting part 20 with any limiting groove 13 on the motor pressure plate main body 10, then align the annular groove 311 of the connecting part 30 with the second rib 211 of the motor pressure plate adjusting part 20, and at the same time, align the opening 321 at the top of the connecting part 30 with the hanging column 11, and finally fix the limiting block 12 to the quasi-hanging column 11.

[0069] The method for adjusting the size of the cavity structure of the motor limiting device 300 is as follows:

[0070] like Figure 10 As shown, first, the motor pressure plate adjustment part 20 is rotated out of the motor pressure plate main body 10 in the direction of the arrow shown in the figure, and the first rib 222 is disengaged from the limiting groove 13. At this time, the motor pressure plate adjustment part 20 is not restricted in the direction perpendicular to the axial direction of the motor 100. When moving, since the second rib 211 is clamped on the annular groove 311 of the connecting part 30, it rotates together with the connecting part 30 in the limiting groove 13 of the motor pressure plate main body 10, thereby adjusting the size of the cavity structure of the motor limiting device 300.

[0071] Furthermore, when the connecting portion 30 moves in the direction away from the motor pressure plate main body 10, the cavity structure of the motor limit device 300 increases, and can cooperate with a longer motor 100 to reach the maximum space reserved for the bottom shell; when the connecting portion moves in the direction close to the motor pressure plate main body 10, the cavity structure of the motor limit device 300 decreases, and can cooperate with a shorter motor 100. After moving to a size that can cooperate with the required motor 100, the motor pressure plate adjustment portion 20 is moved along Figure 11The direction of the arrow turns into the motor pressure plate main body 10, that is, the first rib 222 turns into the corresponding limiting groove 13 of the motor pressure plate main body 10, until the second rib 211 reaches the stop block 3111 of the connecting part 30. At this time, the first rib 222 of the motor pressure plate adjustment part 20 is limited by the limiting groove 13 in the axial direction of the motor 100, and the motor pressure plate adjustment part 20 cannot move, that is, it is fixed.

[0072] like Figure 12 As shown, the figure is a schematic diagram of the inner unit with the housing and electrical structure hidden. The motor 100, motor limit device 300, evaporator 400, etc. are all installed on the bottom shell 200. The bottom shell 200 reserves space for the maximum length of the motor 100. The motor 100 and the motor limit device 300 are installed in conjunction with each other, and the motor limit device 300 is installed in conjunction with the evaporator 400. The cavity structure of the motor limit device 300 covers the motor 100, with a certain gap between the two. The motor limit device 300 is a cavity that can cover the motor 100 and leave a certain gap. The side away from the connecting portion 30 can support the installation of the evaporator 400. The side close to the connecting portion 30 has a hanging column 11, a limit groove 13 and other structures. The motor pressure plate main body 10 also has screw holes to facilitate fixed installation on the inner unit bottom shell 200.

[0073] It should be noted that during the installation of the indoor unit, after the rubber ring 102 close to the motor shaft 101 is fixedly installed on the bottom shell 200, the motor limiting device 300 covers the motor 100, and the slot 212 is aligned with the rubber ring 102 at the end of the motor 100, and then the motor limiting device 300 is fixedly installed on the bottom shell 200. At this time, the two ends of the motor 100 are completely fixed, and the axial direction of the motor 100 is limited by the limiting groove 13 of the motor pressure plate main body 10, and the radial direction is limited by the cooperation between the rubber ring 102 and the bottom shell 200, so the motor 100 will not shake during operation, avoiding abnormal noise. Subsequently, the evaporator 400 will be installed in conjunction with the motor limiting device 300, and the other parts of the air conditioner indoor unit can be assembled as usual.
