Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to motor mounting structures. Background Technology

[0002] Motors are usually fixed to the volute using a bracket. However, the internal space of the equipment using the motor and volute is limited, which restricts the installation process when mounting the bracket to the volute. Therefore, longer screws are used to facilitate the mounting of the bracket to the volute, resulting in part of the screw protruding after it is fixed.

[0003] After prolonged use, motors are prone to failure. In most cases, the volute housing does not need to be replaced, while the bracket fixed to the volute housing is replaced at the same time. Therefore, routine maintenance and repair usually only require removing the motor from the bracket to complete the replacement or repair, without replacing the bracket and volute housing. However, in the current fixing method, the screws that fix the motor are designed on the inside, which makes the long screws used to fix the bracket too protruding when removing the screws that fix the motor, which can easily scratch the hands of assembly or maintenance personnel. At the same time, the long screws used to fix the bracket are prone to loosening due to vibration during use, thereby reducing the service life of the fan. Utility Model Content

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figures 1 to 4 As shown, the motor mounting structure includes a volute 100, a motor 200, and a bracket 300. The motor 200 includes a housing 210, which is provided with connecting lugs 220. The bracket 300 includes an upper support plate 310, a lower support plate 320, and an inclined plate 330. The two ends of the inclined plate 330 are respectively connected to the upper support plate 310 and the lower support plate 320. The upper support plate 310 extends horizontally outward from the upper end of the inclined plate 330, and the lower support plate 320 extends horizontally inward from the lower end of the inclined plate 330, making the bracket 300 Z-shaped. The upper support plate 310 is connected to the connecting lugs 220 by screws. When replacing or repairing the motor 200, only the screws need to be removed to remove the motor, and the bracket 300 can be replaced along with the volute.

[0033] Meanwhile, the lower support plate 320 is connected to the volute 100 by rivets; because the bracket 300 and the volute 100 are connected by rivets, and the lower support plate 320 is located on the inside, it is not easy for assembly personnel or maintenance personnel to access it, so that the hands of assembly personnel or maintenance personnel will not be interfered with during assembly and assembly; at the same time, the rivets will not loosen due to fan vibration, thus increasing the service life of the fan.

[0034] In addition, since the bracket 300 is Z-shaped, a clearance is formed below the upper support plate 310, which can be easily connected to the connecting lug 220 with threaded parts, providing convenience for assembly or disassembly.

[0035] In some embodiments, the upper support plate 310 and the ear piece 220 are provided with corresponding through holes. The through holes may have internal threads to facilitate screw connection. It is understood that the through holes can also be smooth holes. A screw is inserted from one end of the through hole, and a nut is provided at the other end. The screw and nut cooperate to fix the upper support plate and the ear piece 220. In some embodiments, the number of connecting ear pieces 220 is three; of course, the number of connecting ear pieces 220 can also be two, four, five, or more. Preferably, the number of brackets 300 corresponds one-to-one with the number of connecting ear pieces 220.

[0036] Reference Figure 4 As shown, the motor 200 includes an upper housing 211 and a lower base plate 212, with the upper housing 211 fastened onto the lower base plate 212.

[0037] The bottom of the upper housing 211 is provided with an outer ring 2111, the outer ring 2111 is provided with an upper ear piece 221, and the lower bottom plate 212 is provided with a lower ear piece 222. The lower ear piece 222 and the upper ear piece 221 are combined to form a connecting ear piece 220. The number of upper and lower ear pieces corresponds to the number of connecting ear pieces.

[0038] In some embodiments, the upper housing 211 has a cavity, and the cavity contains motor components such as magnets and winding groups. The lower base plate 212 at least partially closes the cavity (preferably substantially or completely closes it).

[0039] In some embodiments, the upper housing 211 is a cylinder with an internal cavity, and the lower base plate 212 is also circular.

[0040] By providing an outer ring 2111 at the bottom of the upper housing 211, the upper lug 221 can protrude from the periphery of the upper housing 211, and the lower lug 222 of the lower base plate 212 can also protrude. In this way, the connecting lug 220 formed by the combination of the upper lug 221 and the lower lug 222 can protrude relative to the upper and lower housings, so as to be able to connect with the outwardly extending upper support plate 310. Since the connecting lug 220 protrudes outward, it is also convenient to make threaded connections (such as screwing in and out screws).

[0041] The upper ear piece 221 has a positioning hole 2211, and the lower ear piece 222 has a positioning protrusion 2221. The positioning protrusion 2221 extends into the positioning hole 2211, allowing the upper ear piece 221 and the lower ear piece 222 to be quickly positioned and assembled. The positioning protrusion 2221 can also be provided on the upper ear piece 221, and the positioning hole 2211 can also be provided on the lower ear piece 222. It is understood that the positioning hole 2211 and the positioning protrusion 2221 can be any matching shape, such as cylindrical or cuboid. The aforementioned positioning hole and positioning protrusion can be provided on one of the upper ear pieces 221 and the lower ear piece 222, or they can be provided on each of the upper ear pieces 221 and the lower ear piece 222.

[0042] Reference Figure 4 , 5 As shown, in this embodiment, the edge of the lower base plate 212 is bent upward with a baffle 2121. The baffle 2121 blocks the outer edge of the outer ring 2111 to fix the lower base plate 212, so as to prevent the lower base plate 212 from shifting after it is combined with the upper shell 211, which facilitates subsequent welding, riveting or threaded connection and fixation.

[0043] Secondly, the outer ring 2111 can also be bent to have a baffle 2121. The baffle 2121 blocks the outer edge of the lower base plate 212, so that the lower base plate 212 will not shift after it is combined with the upper shell 211.

[0044] In some embodiments, the number of baffles 2121 is multiple, for example Figure 4 At least five baffles are provided, with the five baffles surrounding the outer perimeter of the lower base plate 212. When the lower base plate 212 is installed in conjunction with the upper housing 211, the baffles 2121 are located outside the outer wall of the upper housing 211, thereby limiting the relative displacement between the lower base plate 212 and the upper housing 211, and also avoiding interference with the components inside the motor cavity.

[0045] Reference Figure 4 The upper housing 211 has a notch 2112, which allows heat dissipation from the inner cavity of the upper housing 211. At the same time, a cover 230 is fastened to the notch 2112 to seal the notch 2112.

[0046] The number of notches 2112 can be selected without affecting the strength of the upper shell 211, and the notches 2112 can be closed according to actual usage requirements.

[0047] Reference Figure 1 An air inlet 110 is provided at the bottom of the volute 100, and a bottom shell 400 is fixed at the bottom of the volute 100. A bottom air outlet 410 is opened on the bottom shell 400, and a ring plate 411 is bent upward at the edge of the bottom air outlet 410. The ring plate 411 is inserted into the air inlet 110 to ensure that the bottom shell 400 and the volute 100 are accurately aligned and to ensure accurate installation during assembly. At the same time, the ring plate 411 can also restrict the movement of the volute 100 after the bottom shell 400 and the volute 100 are assembled, so as to facilitate welding or riveting of the bottom shell 400 and the volute 100.

[0048] In addition, the ring plate 411 also extends downward from the air inlet 110. In this embodiment, the diameter of the bottom air inlet 410 is smaller than the diameter of the air inlet 110, so that the ring plate 411 can be inserted into the bottom air inlet 410. This can also achieve accurate alignment between the bottom shell 400 and the volute 100, and restrict the movement of the volute 100 after the bottom shell 400 and the volute 100 are assembled, so as to facilitate welding or riveting of the bottom shell 400 and the volute 100.

[0049] Reference Figure 3 , 6 The volute 100 is provided with an air outlet 120, and an air outlet bend 500 is installed at the air outlet 120. An anti-reverse plate 600 is installed inside the air outlet bend 500. When the fan is working, the air blows the anti-reverse plate 600, causing the anti-reverse plate 600 to fold in half, thereby releasing the seal of the inner cavity of the air outlet bend 500. When the fan stops working, the anti-reverse plate 600 unfolds to seal the air outlet bend 500.

[0050] Reference Figure 6 The air outlet bend 500 includes a first half-pipe 510 and a second half-pipe 520, which are interlocked. The first half-pipe 510 has a retaining plate 511 on its edge, and the second half-pipe 520 has a U-shaped buckle 521 on its edge. The retaining plate 511 is inserted into the U-shaped buckle 521 so that the first half-pipe 510 and the second half-pipe 520 are combined into a whole and ensure that the first half-pipe 510 and the second half-pipe 520 do not shift relative to each other.

[0051] Meanwhile, the edge of the first half tube 510 can also be provided with a U-shaped buckle 521, and the edge of the second half tube 520 can also be provided with a retaining plate 511, which can also achieve the stability of the combination between the first half tube 510 and the second half tube 520.

[0052] To ensure stability of the assembly, the lengths of the U-shaped buckle 521 and the clamping plate 511 can be selected according to the arc lengths of the edges of the first half-tube 510 and the second half-tube 520, thereby achieving a seal after assembly.

[0053] Implementation method 1: The length of the U-shaped buckle 521 and the card plate 511 can be the same as the arc length of the edge of the first half tube 510 and the second half tube 520;

[0054] Implementation method 2: Multiple U-shaped buckles 521 can be used. The number of clamping plates 511 is set according to the number of U-shaped buckles 521, so that the number of U-shaped buckles 521 and clamping plates 511 corresponds one-to-one. The number of U-shaped buckles 521 for sealing can be equally divided according to the arc length of the edge of the second half tube 520, so as to ensure uniform and stable force.

[0055] Reference Figure 8 , 9 As shown, a through-hole 5211 is opened on the U-shaped buckle 521, and a snap fastener 5112 is provided on the clamping plate 511. The snap fastener 5112 passes through the through-hole 5211 from a vertical position and is then pressed into a horizontal position to prevent the clamping plate 511 from coming out of the U-shaped buckle 521. There are multiple through-holes 5211 and snap fasteners 5112, and they are evenly arranged to ensure the stability of the combination between the clamping plate 511 and the U-shaped buckle 521.

[0056] Reference Figure 6 As shown, the check valve 600 includes a sub-valve plate 610 and a valve stem 620. Two sub-valve plates 610 are used, and the valve stem 620 is inserted between the two sub-valve plates 610. The two ends of the valve stem 620 are inserted into the air outlet bend 500. Air is blown from the air outlet of the air outlet bend 500 to the check valve 600. The sub-valve plates 610 do not flip, so that the air outlet bend 500 has a one-way air path, preventing foreign objects from entering or backflow of air.

[0057] The fan blows air onto the two valve plates 610, causing them to fold and releasing the seal on the inner cavity of the outlet bend 500. When the fan stops working, the two valve plates 610 are no longer blown by the air, causing them to reset and unfold, resealing the outlet bend 500 and blocking the air passage inside the outlet bend 500.
