[0003] The main purpose of a motor mounting structure in the prior art is to solve the technical problem in the prior art that the motor wire is easily pulled during wiring, causing the motor to be skewed and produce friction noise. The main technical solution adopted is: the outer surface of the motor mounting plate is provided with a wiring area; the motor wire pressing plate is in conflict with the motor wire in the wiring area, and cooperates with the motor mounting plate to press and fix the motor wire, so that the motor wire cannot be pulled, thereby effectively preventing the motor wire from being pulled during the wiring process, causing the motor to be skewed and produce friction noise. However, the disadvantage of adopting this solution is that the motor wire is clamped at the outlet, causing the motor to transmit vibration to the fuselage, thereby causing abnormal vibration of the whole machine.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] The present invention provides a motor mounting plate, please refer to Figures 1 to 14 , comprising: a mounting plate body 11; a sealing rib 12, wherein the sealing rib 12 is arranged on the mounting plate body 11 so that the wind shield 60 of the air conditioner is in sealing contact with the sealing rib 12, so that a ventilation area is enclosed between the motor mounting plate 10 and the wind shield 60.

[0038] The motor mounting plate in the present invention includes a mounting plate body 11 and a sealing rib 12, wherein the sealing rib 12 is disposed on the mounting plate body 11, so that the sealing rib 12 is in sealing contact with the windshield 60, so that the windshield 60 of the air conditioner and the motor mounting plate can be sealed and a ventilation area can be formed, thereby utilizing the ventilation area to form a part of the air duct of the air conditioner. It can be seen that the motor mounting plate in the present invention can be used to form the air duct of the air conditioner, so the motor mounting plate has more functions, which breaks through the functions of the motor mounting plate in the prior art and solves the problem that the functions of the motor mounting plate in the prior art are relatively single.

[0039] Since the air conditioner involved in the present application has two fan structures, that is, has two motor mounting plates, in order to achieve the universality of the motor mounting plates, such as Figures 1 to 4 As shown, the sealing rib 12 includes a first rib portion 121 and a second rib portion 122 arranged in parallel, so that according to the assembly between the motor mounting plate 10 and the wind shield 60, the first rib portion 121 or the second rib portion 122 is selected to be in sealing contact with the wind shield 60.

[0040] In the air conditioner, two motor mounting plates are arranged in the vertical direction, the second rib portion 122 of the upper motor mounting plate is in sealing contact with the wind shield 60 , and the first rib portion 121 of the lower motor mounting plate is in sealing contact with the wind shield 60 .

[0041] In order to ensure the sealing effect, sealing cotton is sandwiched between the first convex rib portion 121 and / or the second convex rib portion 122 and the wind shield plate 60.

[0042] Specifically, Figure 4 As shown, the sealing rib 12 includes a third rib portion 123, the first end of the first rib portion 121 and the first end of the second rib portion 122 are both connected to the third rib portion 123, the second end of the first rib portion 121 and the second end of the second rib portion 122 are in contact, and at least a portion of the first rib portion 121 and at least a portion of the second rib portion 122 are arranged at intervals. The third rib portion 123 is divided into two parts, the first rib portion 121 and a part of the third rib portion 123 form a first rib strip, and the second rib portion 122 and another part of the third rib portion 123 form a second rib strip.

[0043] To match the ventilation profile of the ventilation area, such as Figure 4 As shown, along the direction away from the third convex rib portion 123, the distance between the first convex rib portion 121 and the second convex rib portion 122 first gradually increases and then gradually decreases.

[0044] In this embodiment, the motor mounting plate also includes: a wiring protrusion 13, and a wiring structure is formed between the mounting plate body 11, the wiring protrusion 13 and the air conditioner volute 30 so that the power cord 41 of the motor 40 connected to the motor mounting plate 10 is limited within the wiring structure.

[0045] During the use of the motor mounting plate, the power line 41 of the motor 40 needs to pass through the motor mounting plate. For this purpose, a wiring protrusion 13 is provided on the motor mounting plate to limit the wiring protrusion 13 .

[0046] The wiring structure in this embodiment has the following two forms:

[0047] The first structural form: Figure 4 As shown, the wiring structure includes a wiring groove 131, and the wiring groove 131 is arranged between the limiting rib 31 of the volute 30 and the outer periphery of the mounting plate body 11;

[0048] The second structural form: Fig.13 As shown, the wiring structure includes a limiting plate 14 disposed on the mounting plate body 11 , and a wiring groove 131 is disposed between the limiting plate 14 and the outer periphery of the mounting plate body 11 .

[0049] For the second structural form, the wiring groove is only formed on the motor mounting plate 10, and no corresponding ribs need to be provided on the volute. This solution makes the motor mounting plate model structure more complicated and makes the volute structure simpler.

[0050] In this embodiment, the wiring protrusion 13 is arranged on the side of the wiring groove 131 away from the volute 30. In this embodiment, by arranging the wiring protrusion 13 on the side of the wiring groove 131 away from the volute 30, the wiring protrusion 13 can form a stopper effect on the opening of the wiring groove 131, thereby preventing the power cord 41 from falling out of the wiring groove 131.

[0051] In addition, there are multiple wiring protrusions 13, and the multiple wiring protrusions 13 are arranged at intervals along the circumference of the mounting plate body 11. In this way, the stopping effect of the power line 41 can be improved.

[0052] Specifically, when the wiring groove 131 is composed of a limiting rib 31, the limiting rib 31 includes a plurality of rib segments 311, the plurality of rib segments 311 are spaced apart around the mounting plate body 11, and at least a portion of the wiring protrusion 13 is located between two adjacent rib segments 311; when the wiring groove 131 is composed of a limiting plate 14, the limiting plate 14 includes a plurality of limiting plate segments 141, the plurality of limiting plate segments 141 are spaced apart around the mounting plate body 11, and at least a portion of the wiring protrusion 13 is located between two adjacent limiting plate segments 141.

[0053] In order to ensure the stopping effect on the power line 41 , the motor mounting plate further comprises: a wire pressing plate 15 , which is mounted on the mounting plate body 11 to be pressed on the power line 41 of the motor 40 connected to the motor mounting plate 10 .

[0054] In addition, the motor mounting plate in this embodiment further includes a support ridge 16, which is disposed on the mounting plate body 11 so that the power line 41 can be pressed by the wire pressing plate 15 after passing through the support ridge 16. By providing the support ridge 16 in this embodiment, the power line 41 can be pressed by the wire pressing plate 15 after passing through the support ridge 16, thereby preventing the power line 41 from being tightened.

[0055] In this embodiment, the motor mounting plate is fixed to the volute by four screws. The sealing ribs on the motor mounting plate are sealed with the wind shield. A wiring structure is arranged around the motor mounting plate. Ribs (support ribs) are arranged at the outlet of the motor to prevent the motor wire from being stuck. The wiring of the ribs is as follows: Fig.12 As shown in A.

[0056] A rib (support convex strip 16) is provided between the wire pressing plate and the motor wire outlet position, which can prevent the motor wire from being straightened and clamped between the wire outlet position and the wire pressing plate during the pre-installation process of the motor assembly, so that the motor transmits vibration to the fuselage, resulting in abnormal vibration of the whole machine.

[0057] There is another way to implement the wiring structure of this application, such as Fig.14 As shown, a limiting groove 111 is provided on the mounting plate body 11 for accommodating the power cord 41 of the motor 40 connected to the motor mounting plate 10, and the minimum distance between the two opposite side walls of the limiting groove 111 is greater than the predetermined distance so that the power cord 41 can be movably set in the limiting groove 111.

[0058] During the pre-installation stage, the staff ensured that the motor wire was not tightened at this position to reduce the transmitted vibration. At the same time, the vibration of the motor wire would not touch the sides during operation to avoid abnormal noise.

[0059] It is worth noting that the predetermined distance here is the width of the limiting groove 111 which is at least twice greater than the diameter of the power cord 41 .

[0060] The present invention further provides an air conditioner, comprising a volute 30, a wind shield 60, and a motor mounting plate 10 disposed on the volute 30, wherein the motor mounting plate 10 is the above-mentioned motor mounting plate.

[0061] Preferably, the volute 30 includes an upper volute 71 and a lower volute 72, the fan blades 90 of the air conditioner are arranged between the upper volute 71 and the lower volute 72, and the motor mounting plate 10 is mounted on the upper volute 71. The upper volute 71 is provided with a transition rib 711 for connecting the second rib portion 122 of the motor mounting plate located above and the first rib portion 121 of the motor mounting plate located below.

[0062] In this embodiment, a sealing ridge 32 is provided on the volute 30, and the sealing ridge 32 is arranged opposite to the sealing ridge 12 of the motor mounting plate 10, and the wind shield 60 is in sealing contact with the sealing ridge 12, so that a ventilation area is enclosed between the wind shield 60, the sealing ridge 32, the sealing ridge 12, the volute 30 and the mounting plate body 11 of the motor mounting plate 10.

[0063] Preferably, the motor mounting plate 10 and the volute 30 are connected by a concave-convex matching structure.

[0064] The motor mounting plate in this embodiment not only has the basic function of fixing the motor, but also seals with the wind shield to form the air duct structure of the air conditioner.

[0065] The motor mounting plate in this embodiment solves the following technical problems:

[0066] 1. The motor mounting plate has a wiring structure that matches the ribs on the volute. This structure allows the parts to be processed and formed by a moving die, avoiding the use of a core-pulling process to form a groove for wiring, reducing the difficulty of mold processing and reducing costs.

[0067] 2. The motor mounting plate is sealed with the wind shield to form a diffusion section, which can effectively prevent the airflow from diffusing, making the wind speed high and the air delivery distance long.

[0068] 3. Add reinforcement (support convex strip 16) at the outlet of the motor. The rib can prevent the motor wire from being clamped and fixed between the outlet position and the wire pressing plate during the pre-installation process, so that the motor transmits vibration to the machine body, thereby causing abnormal vibration of the whole machine.

[0069] The motor mounting plate in this embodiment reduces the difficulty of mold processing, reduces costs, and can effectively prevent the diffusion of the airflow passing through, so that the wind speed is high and the air supply distance is long. At the same time, it can prevent the motor from transmitting vibration to the fuselage, causing abnormal vibration of the whole machine.

[0070] In this technical solution, the motor mounting plate is fixed to the volute by four screws. Pin positioning is adopted, and the three pin holes are respectively located near the three screw holes, which play the role of positioning and preventing reverse installation. The ribs on the motor mounting plate are sealed with the wind shield, and the upper and lower motor mounting plates in the double-blade air duct are universal. The thickness of the motor mounting plate is 9mm to 15mm, and it is reinforced by a concave-convex package structure. That is, a reinforcing groove 17 is provided on the motor mounting plate. The motor bracket 80 fixes the motor to the motor mounting plate by four screws. A rib (support convex strip 16) is grown between the wire pressing plate and the motor outlet position. The protruding structure of the circumference (wiring protrusion) cooperates with the ribs (limiting convex rib 31) on the volute to form a wiring structure.

[0071] A wiring structure is added around the motor mounting plate to cooperate with the ribs on the volute. This structure allows the volute to be formed by moving and fixed molds, avoiding the use of core pulling, reducing the difficulty of mold processing and reducing costs.

[0072] During cooling, the airflow from the lower centrifugal blades enters the air duct sealed by the wind shield and the volute from the left side of the middle of the volute. The right side of the duct is sealed at two ribs on the wind shield and the motor mounting plate to form a pressure expansion section, which can effectively prevent the airflow from diffusing to the right, so that the air outlet speed at the head of the air conditioner is high and the air supply distance is long. During heating, the lower airflow is the same as the upper airflow during cooling.

[0073] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0074] The motor mounting plate in the present invention includes a mounting plate body 11 and a sealing rib 12, wherein the sealing rib 12 is disposed on the mounting plate body 11, so that the sealing rib 12 is in sealing contact with the windshield 60, so that the windshield 60 of the air conditioner and the motor mounting plate can be sealed and a ventilation area can be formed, thereby utilizing the ventilation area to form a part of the air duct of the air conditioner. It can be seen that the motor mounting plate in the present invention can be used to form the air duct of the air conditioner, so the motor mounting plate has more functions, which breaks through the functions of the motor mounting plate in the prior art and solves the problem that the functions of the motor mounting plate in the prior art are relatively single.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
