Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioning, and in particular to a mounting bracket, a fan and an air conditioning device. Background Art

[0002] As people's living standards continue to improve, air conditioning equipment is becoming more and more popular. In air conditioning equipment, fans are usually used to achieve air circulation and ventilation and heat exchange of the air conditioning system.

[0003] In the related art, when the fan is rotating, the fan bracket plays the role of supporting and fixing the motor. However, during the supporting and fixing process, the fan bracket is prone to fatigue failure due to the rotation of the fan. Utility Model Content

[0004] In view of this, the present disclosure provides a mounting bracket, a fan and an air conditioning device. The mounting bracket and the fan can reduce the risk of structural fatigue failure, thereby improving the reliability of the operation of the air conditioning device.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0006] According to a first aspect of an embodiment of the present disclosure, a mounting bracket is provided, comprising a mounting seat, a plurality of connecting arms and a plurality of first connecting members. The mounting seat is provided with a mounting portion for fixedly connecting to a motor. The plurality of connecting arms are arranged at intervals along the edge of the mounting portion, the connecting arm comprising an arm body, a first connecting portion fixedly connected to the mounting portion and a second connecting portion fixedly connected to a fixed component, one end of the arm body is fixedly connected to the first connecting portion, and the other end is fixedly connected to the second connecting portion, and the arm body is provided with at least two fixing portions arranged at intervals along the direction from the first connecting portion to the second connecting portion. At least one first connecting member is connected between two adjacent connecting arms, and one end of the first connecting member is connected to the fixing portion of one of the connecting arms, and the other end is connected to the fixing portion of the other connecting arm. Relative to the mounting portion, the distance from one end of the first connecting member to the first connecting portion of the connecting arm connected thereto is L1, and the distance from the other end of the first connecting member to the first connecting portion of the connecting arm connected thereto is L2, and L1 is not equal to L2.

[0007] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0008] When the motor is working, the motor will apply a rotational force to the mounting bracket, that is, a rotational force is applied to the connecting arm. The various fixed parts on the connecting arm move with different phases and different amplitudes. At least one first connecting member is connected between two adjacent connecting arms, one end of the first connecting member is connected to the fixed part of one of the connecting arms, and the other end is connected to the fixed part of the other connecting arm. And relative to the mounting part, the distance L1 from one end of the first connecting member to the first connecting part of the connecting arm connected thereto is not equal to the distance L2 from the other end of the first connecting member to the first connecting part of the connecting arm connected thereto. In other words, the distances from the fixed parts connected to the two ends of the first connecting member to the first connecting part of its connecting arm are not equal. Therefore, the fixed parts connected to the two ends of the first connecting member move with different phases and different amplitudes, so that the adjacent connecting arms are mutually constrained by the first connecting member, thereby improving the stiffness of the mounting bracket, especially the rotational stiffness of the mounting bracket, thereby reducing the risk of fatigue failure of the mounting bracket.

[0013] In one embodiment, the fixing portion is provided with a limiting groove, and at least a portion of the first connecting member is disposed in the limiting groove to be connected to the connecting arm.

[0014] In one embodiment, the mounting bracket further includes a second connecting member, and the connecting arm is fixedly connected to the mounting base via the second connecting member.

[0015] In one embodiment, the mounting seat is provided with a mounting slot, and at least a portion of the motor passes through the mounting slot.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0035] As people's living standards continue to improve, air conditioning equipment is becoming more and more popular, and consumers are also demanding more and more from it. At present, there are many types and brands of air conditioning equipment, which makes consumers have many choices. How to win the favor of consumers and improve product competitiveness has become an issue that air conditioning equipment manufacturers are paying more and more attention to.

[0036] At present, in addition to paying attention to the cooling and heating effects of air conditioners, people also have increasingly higher requirements for safety. High performance, safety and reliability are one of the important indicators for improving product competitiveness.

[0037] In the related art, when the fan is rotating, the fan bracket supports the fan and fixes the motor. However, during the support and fixation process, the fan bracket is prone to fatigue failure due to the rotation of the fan.

[0038] Based on this, the present disclosure provides a mounting bracket, a fan and an air conditioning device, wherein the mounting bracket and the fan can reduce the risk of structural fatigue failure, thereby improving the reliability of the operation of the air conditioning device.

[0039] In order to better understand the mounting bracket of the present invention, a fan and an air conditioning device using the mounting bracket are used for illustration.

[0040] The present disclosure provides an air conditioning device, the air conditioning device includes a fan. Specifically, in one example, the air conditioning device includes an indoor unit and an outdoor unit, the outdoor unit includes a casing, and the fan is installed in the casing.

[0041] In another example, the air conditioning device includes an air-cooled chiller, and the fan is installed on the air-cooled chiller.

[0042] like Figure 1 As shown, in some embodiments, the fan 10 includes a wind wheel 100, a motor 200, a protective assembly 300 and a mounting bracket 400. The wind wheel 100 includes a hub 110 and a plurality of blades 120 arranged on the outer peripheral wall of the hub 110. The motor 200 includes an output shaft connected to the hub 110 to drive the wind wheel 100 to rotate. The protective assembly 300 is provided with a cavity 310, and the wind wheel 100 is arranged in the cavity 310. The mounting bracket 400 is fixedly connected to the protective assembly 300. In this way, when the air-conditioning device is working, the output shaft of the motor 200 drives the wind wheel 100 to rotate, so that the air-conditioning device realizes air circulation and ventilation and heat exchange through the fan 10. Among them, the protective assembly 300 can protect the wind wheel 100 and the motor 200.

[0043] Optionally, the fan 10 may be an axial flow fan, a centrifugal fan, or the like.

[0044] It can be understood that the fan 10 can also be used for ventilation and heat exchange in general factories, warehouses, offices, residences and the like, and can also be used as a cold air fan 10 (air cooler), evaporator, condenser and the like.

[0045] In the practice of the present disclosure, the researchers found that the bracket is the main component that provides support for the motor and the fan. The bracket generally has multiple support arms, and a crossbeam is added between adjacent support arms to connect the adjacent support arms together to improve the integrity of the bracket. However, these crossbeams are usually installed at the same position of two adjacent support arms, which cannot improve the rigidity of the bracket in the direction of rotation around the motor shaft, because the positions where the crossbeams are connected are in the same phase and amplitude during rotation, and cannot play a role of mutual restraint.

[0046] The mounting bracket 400 disclosed in the present invention can reduce the risk of structural fatigue failure. Figures 2 to 4 As shown, in some embodiments, the mounting bracket 400 includes a mounting seat 410, a plurality of connecting arms 420 and a plurality of first connecting members 430. The mounting seat 410 is provided with a mounting portion 411 for fixed connection with the motor 200. The plurality of connecting arms 420 are arranged at intervals along the edge of the mounting portion 411. The connecting arm 420 includes an arm body 421, a first connecting portion 422 fixedly connected to the mounting portion 411 and a second connecting portion 423 for fixed connection with the fixing portion 401. One end of the arm body 421 is fixedly connected to the first connecting portion 422, and the other end is fixedly connected to the second connecting portion 423. The arm body 421 is provided with at least two fixing portions 401 spaced from the first connecting portion 422 to the second connecting portion 423. At least one first connecting member 430 is connected between two adjacent connecting arms 420, and one end of the first connecting member 430 is connected to the fixing portion 401 of one of the connecting arms 420, and the other end is connected to the fixing portion 401 of the other connecting arm 420. Relative to the mounting portion 411 , the distance from one end of the first connecting member 430 to the first connecting portion 422 of the connecting arm 420 connected thereto is L1, and the distance from the other end of the first connecting member 430 to the first connecting portion 422 of the connecting arm 420 connected thereto is L2, and L1 is not equal to L2.

[0047] Thus, when the air conditioner is working, the motor 200 drives the wind wheel 100 to rotate, and the motor 200 applies a rotational force to the mounting bracket 400, that is, applies a rotational force to the connecting arm 420. The fixing parts 401 on the connecting arm 420 move with different phases and amplitudes. At least one first connecting member 430 is connected between two adjacent connecting arms 420, one end of the first connecting member 430 is connected to the fixing part 401 of one connecting arm 420, and the other end is connected to the fixing part 401 of the other connecting arm 420. And relative to the mounting part 411, the distance L1 from one end of the first connecting member 430 to the first connecting part 422 of the connecting arm 420 connected thereto is not equal to the distance L2 from the other end of the first connecting member 430 to the first connecting part 422 of the connecting arm 420 connected thereto. In other words, the distances from the fixing parts 401 connected to the two ends of the first connecting member 430 to the first connecting part 422 of its connecting arm 420 are not equal. Therefore, the fixing parts 401 connected at both ends of the first connecting member 430 move with different phases and amplitudes, so that the adjacent connecting arms 420 are mutually constrained by the first connecting member 430, thereby improving the rigidity of the mounting bracket 400, especially the rotational rigidity of the mounting bracket 400, thereby reducing the risk of fatigue failure of the mounting bracket 400. In turn, the operating reliability of the fan 10 and the air conditioning equipment is improved.

[0048] It should be noted that the distance from one end of the first connecting member 430 to the first connecting portion 422 of the connecting arm 420 connected thereto and the distance from the other end of the first connecting member 430 to the first connecting portion 422 of the connecting arm 420 connected thereto refer to the distance along the path of the connecting arm 420.

[0049] It should be noted that there are many ways to fix the arm body 421 with the first connection part 422 and the second connection part 423, including welding, clamping, integral molding, etc.

[0050] like Figure 3 As shown, in one example, the arm body 421 is welded and fixed to the second connecting portion 423. This connection method is simple, easy to manufacture and has high connection strength.

[0051] It should be noted that there are many ways to fix the first connection portion 422 and the mounting portion 411, including welding, screwing, clamping, integral molding, etc.

[0052] like Figure 3 As shown, in one example, the arm body 421 is welded and fixed to the first connecting portion 422, and the first connecting portion 422 is welded and fixed to the mounting portion 411. In this way, the connection strength between the connecting arm 420 and the mounting seat 410 can be improved as a whole.

[0053] It should be noted that there are many ways to fix the motor 200 and the mounting portion 411, including snap-on fixation, screw-on fixation, riveted fixation, etc.

[0054] It should be noted that there are many ways to connect the first connecting member 430 and the connecting arm 420, including welding, clamping, etc.

[0055] In some embodiments, the fixing portion 401 is provided with a limiting groove, and at least part of the first connecting member 430 is installed in the limiting groove to connect with the connecting arm 420. In this way, the first connecting member 430 is installed in the first connecting member 430 through the limiting groove, and the limiting groove can play a role in positioning and limiting.

[0056] In some embodiments, at least a portion of the first connector 430 is welded to the connecting arm 420 via the limiting groove. Thus, the first connector 430 is arranged in the limiting groove so that the first connector 430 and the fixing portion 401 have a larger contact area, thereby improving the welding strength between the first connector 430 and the connecting arm 420.

[0057] In order to further improve the manufacturing efficiency of the mounting bracket 400. In other embodiments, the plurality of first connecting members 430 are integrally formed.

[0058] In some embodiments, in a top view of the mounting bracket, Figure 2 In the X direction shown, the first connecting members 430 may be integrally formed in a polygonal shape such as a triangle or a quadrilateral, or may be in a circular shape, an elliptical shape, or at least partially in a circular shape.

[0059] In one example, in a top view of the mounting bracket, that is, Figure 2 In the X direction shown, a plurality of first connecting members 430 are integrally formed in a circular ring shape, and the first connecting members 430 in a circular ring shape are eccentrically mounted on a plurality of connecting arms 420. At this time, the connection between the first connecting member 430 and each connecting arm 420, that is, the fixed portion 401, is at different distances from the first connecting portion 422 of the connecting arm 420 to which it is connected. In this way, the fixed portion 401 connected by the first connecting member 430 moves with different phases and amplitudes, so that adjacent connecting arms 420 are mutually constrained by the first connecting member 430, thereby improving the rigidity of the mounting bracket 400, especially the rotational rigidity of the mounting bracket 400, thereby reducing the risk of fatigue failure of the mounting bracket 400. This improves the operating reliability of the fan 10 and the air-conditioning equipment.

[0060] like Figure 1As shown, in some embodiments, the fixing portion 401 is the protection component 300 , and the mounting bracket 400 is fixedly connected to the protection component 300 via the second connecting portion 423 , so as to fix the mounting bracket 400 , the wind wheel 100 , and the motor 200 to the protection component 300 .

[0061] like Figure 3 as well as Figure 4 As shown, in some embodiments, the mounting seat 410 is a ring, and a plurality of connecting arms 420 are evenly spaced along the circumference of the mounting seat 410. In this way, the plurality of connecting arms 420 can strengthen the connection strength between the mounting seat 410 and the protective assembly 300. The vibration generated by the motor 200 can be distributed to each connecting arm 420 more evenly, thereby improving the reliability of the connecting arm 420 in supporting and fixing the motor 200. In addition, the plurality of connecting arms 420 are evenly spaced circumferentially, which can also make the air intake of the fan 10 smoother.

[0062] In some embodiments, in a top view of the mounting bracket, Figure 2 In the X direction as shown. Figure 4 As shown, the ring body can be a polygon such as a triangle, a quadrilateral, etc., or it can be a circular ring, an elliptical ring, at least partially a circular ring, etc.

[0063] like Figure 4 As shown, in one example, in a top view of the mounting bracket, the mounting seat 410 is in a circular ring shape, and a plurality of connecting arms 420 are evenly spaced along the circumference of the circular ring-shaped mounting seat 410. In this way, the circular ring-shaped mounting seat 410 can further evenly transmit the vibration generated by the motor 200, so that the vibration generated by the motor 200 can be further evenly distributed to each connecting arm 420, thereby improving the reliability of the connecting arm 420 supporting and fixing the motor 200.

[0064] like Figure 3As shown, in some embodiments, at least two fixing parts 401 include a first fixing part 402 and a second fixing part 403, and the first fixing part 402 is closer to the mounting seat 410 relative to the second fixing part 403. One end of the first connecting member 430 is connected to the first fixing part 402 of one of the connecting arms 420, and the other end is connected to the second fixing part 403 of the adjacent connecting arm 420. In this way, the first fixing part 402 and the second fixing part 403 move with different phases and different amplitudes. By connecting one end of the first connecting member 430 to the first fixing part 402 of one of the connecting arms 420 and the other end to the second fixing part 403 of the adjacent connecting arm 420, the movements of the first fixing part 402 and the second fixing part 403 of the two adjacent connecting arms 420 can be mutually constrained by the first connecting member 430, thereby improving the rigidity of the mounting bracket 400, especially the rotational rigidity of the mounting bracket 400, thereby reducing the risk of fatigue failure of the mounting bracket 400.

[0065] like Figure 4 As shown, in some embodiments, a first connecting member 430 is provided between any two adjacent connecting arms 420. Thus, by providing a first connecting member 430 between adjacent connecting arms 420, the manufacturing efficiency of the mounting bracket 400 can be improved while ensuring the overall strength of the mounting bracket 400.

[0066] like Figure 3 As shown, in some embodiments, the mounting bracket 400 further includes a second connecting member 440 , and the connecting arm 420 is fixedly connected to the mounting base 410 via the second connecting member 440 .

[0067] It should be noted that there are many ways to fix the connecting arm 420 and the mounting seat 410 with the second connecting member 440, including welding, clamping, integral molding, etc.

[0068] like Figure 3 As shown, in some embodiments, the connecting arm 420 is welded and fixed to the second connecting member 440, and the second connecting member 440 is welded and fixed to the mounting seat 410, so that the connecting arm 420 is fixedly connected to the mounting seat 410. In this way, the connecting arm 420 is fixedly connected to the mounting seat 410 through the second connecting member 440, and the contact area between the connecting arm 420 and the second connecting member 440, and the contact area between the second connecting member 440 and the mounting seat 410 is larger, which can improve the welding strength.

[0069] like Figure 3As shown, in some embodiments, the mounting seat 410 is provided with a mounting groove 412, and at least a portion of the motor 200 passes through the mounting groove 412. The mounting bracket 400 further includes a fastener, and the motor 200 is fixedly connected to the second connecting member 440 through the fastener, so that the motor 200 is fixedly connected to the mounting portion 411. In this way, by passing at least a portion of the motor 200 through the mounting groove 412 and fixedly connected to the second connecting member 440 through the fastener, the motor 200 is fixedly connected to the mounting portion 411, thereby improving the fixing effect of the motor 200.

[0070] like Figure 3 As shown, in one example, the fastener includes a nut and a screw fixedly connected to the nut. The second connecting member 440 is provided with a first mounting hole 441, the nut abuts against the second connecting member 440, the screw is passed through the first mounting hole 441, and is screwed and fixed with the nut. In this way, the motor 200 is fixedly connected to the mounting bracket 400 by screwing the screw and the nut to achieve a detachable fixation, which is convenient for maintenance and replacement.

[0071] like Figure 1 As shown, in another example, the fastener includes a screw with an external thread, the motor 200 is provided with a second mounting hole, and the second mounting hole is provided with an internal thread adapted to the external thread. The screw is sequentially inserted into the first mounting hole 441 and the second mounting hole, and the screw is screwed and fixed with the second mounting hole to fix the motor 200 to the mounting bracket 400. In this way, the use of a nut can be avoided, reducing the space occupied by the nut. And the assembly efficiency is improved.

[0072] like Figure 2 As shown, in some embodiments, the arm body 421 is a hollow structure. Thus, by designing the arm body 421 to be a hollow structure, the weight of the mounting bracket 400 as a whole can be reduced, so that the fan 10 can be lightweight.

[0073] It should be noted that the above embodiments can complement each other if there is no conflict.

[0074] The components included in the "component", "device" and "equipment" disclosed in the present invention can also be flexibly combined, that is, modular production can be carried out according to actual conditions and modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device.

[0075] The division of the above components in the present disclosure is only one of the embodiments, for the convenience of reading, rather than limiting the scope of protection of the present disclosure. As long as the above components are included and have the same function, it should be understood that they are equivalent technical solutions of the present disclosure. In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present disclosure.

[0076] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0077] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0078] In the present disclosure, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

Furthermore, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-fitting, integral molding, welding, etc., which can be achieved in traditional technologies and will not be repeated here.

[0080] The technical features of the above embodiments may be combined arbitrarily.
