Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a motor bracket, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] In the outdoor unit of the air conditioner, the motor and the fan blades are the moving parts. Figure 1 and Figure 2 As shown, the fan blade 200 is connected to the motor 100, and the motor is mounted on the motor bracket and fixed in the housing of the air conditioner outdoor unit. Figure 1 As shown, the structure of the existing integrated motor bracket 1' is as follows: the bottom is fixed to the chassis by screws, the upper side facing the condenser is clamped on the condenser, and the upper side facing the panel is fixed to the panel by screws. In order to enhance the structural strength of the bracket, there is also a spliced ​​motor bracket 1' in the prior art, see Figure 2 As shown, the left and right longitudinal beams are made into a U-shaped structure, and the motor mounting plate 101, the chassis connecting plate 103, and the panel connecting plate 102 are fixed on the longitudinal beams by fasteners; the spliced ​​motor bracket 1", the motor bracket assembly efficiency is low. And in the above two motor brackets, since the motor bracket is located on the wind inlet side of the fan blade 200, it is necessary to hollow out the middle of the motor bracket to reduce the wind shielding area.

[0003] The above two motor brackets have at least the following problems: 1. The above two motor brackets need to be fixed in contact with the chassis, condenser and panel. Since the rigidity of the panel and condenser is relatively weak, it is easy to cause noise and vibration of the whole machine; the motor is installed and fixed in the middle position of the motor bracket, and the motor and the motor bracket form a cantilever beam structure. For this structure, the middle part, that is, the motor part, has the weakest rigidity and is easy to cause vibration. 2. The above two motor brackets are almost the same height as the whole machine. Since the motor bracket is located on the wind inlet side of the fan blade, the wind shielding area of ​​the motor bracket is relatively large.

[0004] Some motor brackets are set to a height of half that of the unit, and the motor bracket is only in contact with the chassis, which can alleviate the vibration and noise problems to a certain extent and reduce the windshield area; however, this type of motor bracket has at least the following problems: since the height of the motor bracket is reduced and the middle of the motor bracket is hollowed out in order to reduce the windshield area, the strength of this type of motor bracket is greatly reduced and the stability is poor compared to the above-mentioned integral motor bracket and spliced ​​motor bracket.

[0005] In summary, the applicant has found that the prior art has at least the following technical problems: the existing motor bracket needs to increase its strength due to the large vibration during the operation of the whole machine, but since the motor bracket is on the wind inlet side of the fan blade, it is necessary to hollow out the middle of the motor bracket to reduce the windshield area, which in turn leads to a decrease in the strength and stability of the motor bracket. Therefore, how to reduce the windshield area while taking into account the structural strength and stability of the motor bracket has become an urgent problem to be solved. Summary of the invention

[0006] The object of the present invention is to provide a motor bracket, an air-conditioning outdoor unit and an air conditioner, so as to solve the technical problem in the prior art that the motor bracket has a large windshield area while ensuring the structural strength and stability, and reducing the windshield area of ​​the motor bracket will affect its structural strength and stability; the many technical effects that can be produced by the preferred technical scheme among the many technical schemes provided by the present invention are detailed as follows.

DETAILED DESCRIPTION

[0047] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0048] In the description of the present invention, it should be understood that the terms "center", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "side" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention 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 limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0049] The embodiments of the present invention provide a motor bracket and an air conditioner outdoor unit with high structural strength, good stability and relatively small windshield area.

[0050] Combine the following Figure 1-Figure 13 The technical solution provided by the present invention is described in more detail.

[0051] See also Figure 1 and Figure 2 As shown in the background technology, Figure 1 The vertical height of the integral motor bracket 1' and the spliced ​​motor bracket 1" is almost the same as that of the whole machine. On the one hand, the motor bracket needs to be fixedly connected to the chassis, panel and condenser, which increases the noise and vibration of the whole machine; and the motor is fixed in the middle position of the motor bracket to form a cantilever beam structure, and the middle part has the weakest rigidity and is more likely to cause vibration; on the other hand, the two motor brackets have good strength and stability, but because the motor is fixed in the middle position, the vertical height is high, and the motor bracket is located on the air inlet side of the motor, so the windshield area is large. For the above two commonly used motor brackets, some motor brackets seek to reduce the windshield area, but the structural strength and stability are far lower than the above two motor brackets.

[0052] Embodiment 1

[0053] like Figure 3-Figure 8 As shown, in this embodiment, a motor bracket is provided, which includes a structural reinforcement portion 12 and at least two components for mounting on a device (such as Fig.11 The support part 11 on the base) in the motor 100 is fixedly connected to the motor 100 so that at least part of the motor is located above the motor bracket, and after the fixing is completed, all the support parts 11 are located on both sides of the axis of the motor, such as Figure 8 . For better, see Figure 8 As shown, after the fixing is completed, the support parts 11 are symmetrically arranged on both sides of the axis of the motor.

[0054] The above-mentioned motor bracket 1, on the one hand, connects all the support parts 11 together through the structural reinforcement part 12 to form an integrated structure, wherein the reinforcement part can be connected to the support part 11 as a whole by screw connection, riveting, welding or integral molding, thereby ensuring the structural strength and structural stability of the motor bracket 1, while facilitating the overall assembly, and the integrated structure ensures reliability during transportation; on the other hand, the support part 11 is fixed to the motor 100 and carries the motor at a position at least partially above the bracket 1, so that after the motor and the fan blade 200 are installed, there is no motor bracket 1 on the top of the fan blade 200 to block the wind, and the overall wind blocking area is small.

[0055] After the bracket 1 is fixed to the motor, the support parts 11 are located on both sides of the motor axis. In other words, the airflow generated by the fan can flow through the support parts 11 .

[0056] Compared with the structure in which all the support parts 11 are arranged along the axial direction of the motor, the above structure can prevent the support parts 11 from interfering with the rotating fan blades 200 because the fan blades 200 are fixed at one end of the motor shaft; usually, in order to prevent the support parts 11 from interfering with the fan blades 200, one way is to increase the motor shaft 101, but this way will increase the thickness of the machine body, which is difficult to apply to the increasingly thin shells in order to increase the cabinet capacity. Another way is to reduce the span between the support parts 11, resulting in a significant reduction in the stability of the bracket 1. The above structure of this embodiment is convenient for increasing the span between the support parts 11 on both sides without interfering with the fan blades 200, increasing the matching area between the support parts 11 and the equipment, and improving the stability of the bracket 1; and because the support parts on both sides are located on both sides of the motor shaft 101, increasing the span between the support parts 11 will not affect the thickness of the machine body.

[0057] When the above-mentioned motor bracket 1 is applied to the outdoor unit of the air conditioner, the chassis 300 serves as a device for fixing the support part 11. On the premise that the motor bracket 1 has good structural strength and stability, the motor bracket 1 can be fixedly connected only to the chassis 300, thereby reducing the contact between the bracket 1 and the panel and the condenser, reducing the vibration transmitted to the panel and the condenser, weakening the vibration, and reducing the noise.

[0058] The number of the above-mentioned support parts 11 is at least two, and can also be three, four, etc., without specific limitation. After the motor is assembled, all support parts 11 include two parts arranged opposite to each other and distributed on both sides of the axis of the motor (i.e., both sides of the motor shaft), see Figure 3 and Figure 4 As shown, considering the compactness of the structure, the number of supporting parts 11 in this embodiment is two.

[0059] As an alternative embodiment, see Figure 3 and Figure 4 As shown, the structural reinforcement part 12 and all the supporting parts 11 of this embodiment are an integrally formed structure formed by bending a plate. The integrally formed structure of the motor bracket 1 does not require additional locking parts to connect the parts, which can improve the structural strength; and the reinforcement part 12 and all the supporting parts 11 can be formed by bending a plate, which is easy to process and can further improve the structural strength.

[0060] On the basis of the above-mentioned integrally formed structure, the structural reinforcement part 12 is connected between the two support parts 11, wherein the structural reinforcement part 12 can be located on the air inlet side of all the support parts 11, see Figure 8 and Fig.12As shown, in order to reduce the wind blocking area, the structural reinforcement part 12 is a plate body with ventilation holes 15, and the ventilation holes 15 are arranged to facilitate airflow through the structural reinforcement part 12. Alternatively, the structural reinforcement part 12 is connected to one end of all the supporting parts 11 for connecting with the equipment, that is, located at the bottom of the motor bracket 1. Since the structural reinforcement part 12 does not affect the airflow at this time, the structural reinforcement part 12 is a plate body, and the ventilation holes 15 are not necessary.

[0061] In fact, when the motor bracket 1 is applied to the outdoor unit of the air conditioner, the support portion 11 is connected to the chassis 300, and other components are usually arranged on the chassis 300. In fact, the surface of the chassis 300 is uneven. Therefore, preferably, see Figure 8 and Fig.12 As shown, the structural reinforcement portion 12 is located on the wind inlet side of the support portion 11, which is more conducive to improving the overall structural strength and stability.

[0062] Preferably, the structural reinforcement part 12 is in contact with the equipment; the structural reinforcement part 12 and the support part 11 form at least three parts that contact the motor bracket 1 with the equipment. When the unit is transported, the unit falls. If the unit is placed after transporting, the external force applied to the motor bracket 1 can be dispersed to the structural reinforcement part 12 and the support part 11. At least three of them evenly disperse the external force to ensure the strength and stability of the structure.

[0063] The support portion 11 in this embodiment fixes the motor. Since the support portion 11 needs to fix the motor at a position at least partially above the bracket 1, in order to facilitate the installation of the motor, see Figure 3 , Figure 4 and Figure 8 As shown, the top of the support portion 11 is bent to form a mounting portion 13, and all mounting portions 13 are arranged at intervals and fixedly connected to the motor.

[0064] The mounting portion 13 is a bearing plate formed by bending the top of the support portion 11, which is integrally formed with the support portion 11, has high structural strength, and does not require any extra connectors; and the mounting portions 13 are arranged at intervals to facilitate fixing the motor, increase the span between the support portions 11, and improve the stability of the structure.

[0065] for Figure 1 and Figure 2 For the two motor brackets, fasteners (such as screws) need to be nailed into the brackets horizontally. Affected by the gravity of the motor, the external force borne by the fasteners located below the motor is significantly greater than that of the fasteners located below the motor, which can easily cause uneven force on the fasteners and cause some fasteners to fall off due to excessive force.

[0066] For the above problems, as an optional implementation method, see Figure 8As shown, the mounting portion 13 is arranged parallel to the supporting surface of the device, and a mounting hole 131 for fixed connection with the motor is provided on the mounting portion 13 .

[0067] The mounting portion 13 is parallel to the support surface on the device for supporting and fixing the motor bracket, that is, when the support surface is a horizontal surface, the mounting portion 13 also has a horizontal surface, and the fastener passes through the fixing plate 102 (such as Figure 8 As shown) and mounting holes 131 realize fixed assembly of the motor, the fasteners can be screws, etc., the fasteners are fixed from top to bottom, which is convenient for screwing, and this structure makes all fasteners bear the same force and have high firmness.

[0068] When installing the motor, it is necessary to adjust the position of the motor to position the fixing plate 102 on the motor on the installation portion 13. The assembly process is relatively complicated. In order to improve the assembly efficiency of the motor, as an optional implementation method, Figure 4 and Figure 8 As shown, the side of the mounting portion 13 is bent to form a folded edge 132, and the folded edge 132 is located on one side or two or more sides of the mounting portion 13 to abut against the motor. Figure 8 As shown, after the motor is assembled, the mounting portion 13 extends along the axial direction of the motor.

[0069] When the above-mentioned folded edge 132 is provided on the mounting part 13, the motor with the fixed plate 102 can abut against one folded edge 132 and slide along the extension direction of the mounting part 13, and after sliding into place, the motor can abut against another folded edge 132, the positioning is completed, and then the motor and the mounting part 13 are fixed by fasteners.

[0070] As an optional embodiment, the distance between the two side support parts 11 is equal in width, or, see Figure 3 and Figure 4 As shown, the distance between the two side support parts 11 increases from the mounting end connected to the motor to the support end connected to the device, that is, the distance between the two side support parts 11 increases from top to bottom in the figure, which can increase the span of the motor bracket 1 and enhance the stability of the structure. And because the support parts 11 are distributed on both sides of the motor axis, when the distance between the support parts 11 increases, it will not affect the rotation of the fan blade 200 and will not increase the thickness of the unit.

[0071] Preferably, see Figure 3 As shown, the distance between the supporting parts 11 on both sides gradually increases from the mounting end connected to the motor to the supporting end connected to the equipment.

[0072] Embodiment 2

[0073] To fix the motor bracket 1 on the device, each support part 11 needs to be fixedly connected to the device. Usually, the position of the motor bracket 1 needs to be adjusted first, and then each support part 11 needs to be locked with the device, and the assembly process is relatively cumbersome.

[0074] For the above questions, see Figure 6 , Figure 9-11 As shown, based on the above embodiment, in the motor bracket 1 in this embodiment, the structural reinforcement portion 12 is bent on one side away from the motor shaft 101 to form an insertion portion 122, and there is a slot 301 on the device, and the insertion portion 122 can be inserted into the slot 301 to pre-position the motor bracket 1.

[0075] Preferably, see Figure 6 The insertion portion 122 is an insert formed by bending the structural reinforcement portion 12, and the opening of the slot 301 faces the motor bracket 1. When the insert is inserted into the slot 301, the motor bracket 1 can be pre-positioned. When fixing the support portion 11 and the equipment, it can assist in fixing and prevent the motor bracket 1 from shifting, thereby improving the assembly efficiency of the motor bracket 1.

[0076] The specific structure of the structural reinforcement part 12 is also provided in this embodiment. Figure 4 As shown, when the structural reinforcement part 12 is connected to the air inlet side of all the supporting parts 11, the outer contour of the structural reinforcement part 12 is a rectangle, or a trapezoid, or a combination of a rectangle and a trapezoid spliced ​​together from top to bottom, wherein the rectangle is located above the trapezoid or the trapezoid is located above the rectangle, and the bottom side of the trapezoid is always set toward the equipment.

[0077] The above structure can ensure that the structural reinforcement part 12 gradually widens from top to bottom, thereby increasing the distance between the two side support parts 11 from one end of the installation part 13 to the support end connected to the equipment, which can increase the span of the motor bracket 1 and enhance the stability of the structure.

[0078] As an alternative embodiment, see Figure 5 As shown, the outer contour of the structural reinforcement portion 12 and the shape of the ventilation hole 15 thereon are similar figures, wherein the definition of similar figures well known to those skilled in the art is: two figures with equal corresponding angles and proportional corresponding sides are similar figures. Figure 4 and Figure 5 As shown in the figure, in order to improve the structural strength, the end corners of the ventilation holes 15 in the figure are rounded after chamfering. Of course, the end corners of the ventilation holes can also be not chamfered. The "outer contour shape of the structural reinforcement part 12 and the shape of the ventilation holes 15 thereon are similar to each other" here means that the end corners of the ventilation holes 15 are not considered to be rounded. In other words, for Figure 5For the ventilation hole 15 after the chamfering treatment, the figure formed by the intersection of the extended lines of the edges of the ventilation hole is similar to the outer contour of the structural reinforcement part 12. This structure makes it easy to make the distance between the edge of the ventilation hole 15 and the outer edge of the structural reinforcement part 12 equal, thereby ensuring that the structural strength of the structural reinforcement part 12 is equal at all locations, thereby improving the overall structural strength.

[0079] The number of ventilation holes 15 on the structural reinforcement part 12 is one or more than two. When there are more than two ventilation holes 15, the ventilation holes 15 are distributed in a matrix or stepped manner on the structural reinforcement part 12. The above structure makes it easy to make the distance between the edge of the ventilation hole 15 and the outer edge of the structural reinforcement part 12 equal, ensuring that the structural strength of each part of the structural reinforcement part 12 is equal, thereby improving the overall structural strength.

[0080] Preferably, see Figure 5 As shown, the outer contour of the structural reinforcement part 12 is a trapezoid, and the shape of the ventilation holes 15 thereon are all trapezoidal, and the bottom sides of the trapezoids are all arranged toward the equipment, so that the distances from the edges of the ventilation holes 15 to the outer edges of the structural reinforcement part 12 are equal, which can increase the span between the supporting parts 11 on both sides and ensure the strength of the motor bracket and the stability of the motor bracket and the motor assembly structure.

[0081] As an alternative embodiment, see Figure 4 As shown, the edge of the ventilation hole 15 is bent to form a flange structure 121 to improve strength. The flange structure 121 extends horizontally and can further enhance the strength of the structural reinforcement part 12. When the motor is small and the motor bracket 1 is strong enough, the flange structure 121 may not be provided.

[0082] Embodiment 3

[0083] Based on the above embodiment, this embodiment proposes a specific implementation of the support portion 11, see Figure 7 and Figure 8 As shown, the support part 11 is a plate with ventilation holes 15, which can reduce the windshield area. Since the outer edge of the fan blade 200 is closer to the motor bracket 1 than the installation position of the fan blade 200 and the motor, in order to further prevent the fan blade 200 from colliding with the motor bracket 1 and affecting the rotation of the fan, as an optional implementation, see Fig.12 and Fig.13 As shown, a clearance opening 111 is provided on one side of the support portion 11 facing the motor shaft, and the clearance opening 111 is recessed in a direction away from the motor shaft 101 to prevent the support portion 11 and the fan blade 200 from interfering with each other.

[0084] The structure of the clearance opening 111 can make the structure of the motor bracket 1 more compact without affecting the rotation of the fan blade 200, reduce the span of the assembly structure of the fan blade 200, the motor and the motor bracket 1 along the motor shaft 101 direction (wind inlet direction), and enhance the stability of the structure; when the distance of the unit along the motor shaft 101 direction is sufficient, the clearance opening 111 may not be set to enhance the strength.

[0085] As an alternative embodiment, see Figure 7 As shown, the opening 111 divides the support part 11 into an upper part and a lower part, and a ventilation hole 15 is provided on the upper part and / or the lower part. The shape of the ventilation hole 15 is similar to the outer contour shape of the part where it is located. Similarly, the "similar figures" here refer to two figures with equal corresponding angles and proportional corresponding sides. Figure 7 The "shape of the ventilation hole 15 and the outer contour shape of the part where it is located are similar figures" here refers to the case where the corners of the ventilation hole are rounded. In other words, Figure 7 For the ventilation holes 15 after the chamfering treatment, on the support part 11, the figure formed by the intersection of the extended lines of the edges of the ventilation holes is similar to the outer contour shape of the part where the ventilation holes are located. This structure can also make the distance between the edge of the ventilation holes 15 on the support part 11 and the outer edge of the support part 11 equal, ensuring that the structural strength of each part of the support part 11 is equal, thereby improving the strength of the overall structure.

[0086] As an optional implementation, the end corners of the ventilation holes 15 are rounded to improve the structural strength.

[0087] As an alternative embodiment, see Figure 8 and Fig.11 As shown, the bottom of the support part 11 is bent to form a fixing part 14, and the fixing part 14 is used to be fixedly connected to the device. The fixing part 14 is a plate-like structure formed by bending the bottom of the support part 11. The fixing part 14 and the support part 11 are integrally formed, and no extra fasteners are required, which improves the structural strength and facilitates the fixed connection between the support part 11 and the device. Fig. 9 and Fig.11 As shown, a fixing hole 302 is provided on the chassis 300 of the device, and the fixing hole 302 is aligned with the screw hole on the motor bracket fixing part 14 and is fixedly connected by fasteners such as screws.

[0088] As an alternative embodiment, see Figure 5 and Figure 7As shown, there is an angle rib 17 between the structural reinforcement part 12 and the support part 11, and / or between the support part 11 and the mounting part 13, and / or between the support part 11 and the fixing part 14. There is a rolling rib 16 on the structural reinforcement part 12 and / or the support part 11. The structure of the angle rib 17 can strengthen the connection between the various parts of the motor bracket 1 and improve the strength and stability of the structure; the structure of the rolling rib 16 can improve the strength of the plate structure of the structural reinforcement part 12 and the support part 11.

[0089] Through simulation experiments, the first-order bending mode: the integral motor bracket 1' in the prior art is 31Hz, and the motor bracket in this embodiment is 47Hz. The fixed frequency of this order mode of the motor bracket in this embodiment is higher than that of the integral motor bracket 1', and the bending resistance is better than that of the integral motor bracket, and the strength is high.

[0090] A unit force is applied in the main excitation direction of the fan, and it is concluded from the analysis cloud map that the deformation of the existing spliced ​​motor bracket 1" is 0.0053mm, and the maximum stress is 0.71MPa; the deformation of the motor bracket in this embodiment is 0.0027mm, and the maximum stress is 0.42MPa; compared with the existing spliced ​​motor bracket 1", the deformation of the motor bracket 1 in this embodiment is reduced by 49% and the strength is higher; the maximum stress is reduced by 59%, the internal stress is more dispersed, and the stability is better.

[0091] Therefore, the above experiments can verify that Figure 3 , Figure 4 , Figure 8 and Fig.13 As shown, the motor bracket 1 in this embodiment has a structural strength and stability not lower than the integral motor bracket 1' commonly used in the prior art (such as Figure 1 ) and spliced ​​motor bracket 1" (such as Figure 2 ); however, the windshield area of ​​the motor bracket 1 of this embodiment is much smaller than that of the above two brackets. Compared with the existing motor brackets, it can take into account both improving the structural strength and reducing the windshield area. Therefore, when used in the outdoor unit of the air conditioner, the overall heat exchange performance is higher and the reliability is good. The height and weight of the motor bracket are only half of those of the integral motor bracket 1' and the spliced ​​motor bracket 1".

[0093] This embodiment provides an air-conditioning outdoor unit, including a chassis 300 and the motor bracket 1 , wherein the support portion 11 is mounted and fixed on the chassis 300 .

[0094] The air conditioner outdoor unit with the above-mentioned motor bracket 1 has a support part 11 connected and fixed to the chassis 300. There is no connection between the motor bracket 1 and the condenser, and between the motor bracket 1 and the panel, thereby ensuring the stability of the motor operation and the stability of the condenser. The chassis 300 has a high structural strength, which is beneficial to reducing the noise and vibration of the whole machine, and improving the overall strength and stability of the bracket 1. The windshield area is small, which is beneficial to the heat exchange of the whole machine.
