Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
In a first exemplary embodiment of the present invention, a motor mounting structure is provided. Fig. 2 is a schematic view of a motor mounting structure according to an embodiment of the present invention. As shown in fig. 2, the motor mounting structure of the present invention includes a motor frame 1 and a climbing bar 2, wherein the motor frame 1 and the climbing bar 2 are connected by a screw 4. Wherein, motor frame 1 includes two supporting parts 11, and two supporting parts 11 set up respectively in the both sides of motor 3, fix the fixed part of motor 3 both sides through with a cooperation of holding up and climbing 2.
Specifically, the motor frame 1 is provided with a hanging lug 111 for fixing the holding bar 2 and a limit fixing portion 112. The corresponding design of the holding tab 2 is provided with a first notch 21 corresponding to the hanging lug 111 and a second notch 22 matching with the limit flange 1122. It can be understood that the positions of the hanging lug 111 and the limit fixing part 112 can be interchanged. Fig. 3a is a schematic structural diagram of a motor mount according to an embodiment of the present invention, as shown in fig. 3a, two support portions 11 of the motor mount 1 are substantially parallel flat plates, a connection portion 12 is disposed between the two support portions 11, and the connection portion 12 is perpendicularly connected to the two support portions 11. The two supporting parts 11 are arranged on two sides of the motor 3 to fixedly support the motor 3, and the connecting part 12 is used for fixing the motor frame 1 on the volute plate 6. The hanging lugs 111, the limiting flanges 1122, the air passing openings 113 and the ground feet 114 are arranged on the supporting portion 11 on each side, and the positioning openings 121 are arranged below the connecting portion 12 of the motor frame 1.
Referring to fig. 3a again, the supporting portions 11 on both sides of the motor frame 1 are spaced apart by a predetermined distance, which is determined according to the specific shape and size of the motor 3. The support part 11 on each side is provided with an arc-shaped motor fixing clamping position 115 for being arranged below the cylindrical fixing parts protruding from the two sides of the motor 3 to support the fixing part of the motor 3 and to be matched with the climbing pole 2 with a curved surface arranged above the fixing part of the motor 3 for fixing.
Thus, the clip 2 can be easily hung on the motor frame 1 by the first notch 21, the hanging lug 111, the second notch 22, and the stopper flange 1122 in the after-sales mounting process. At the moment, the holding bar 2 is hung on the motor 3, and the falling prevention is not required to be protected by external force. When the screw is fixed, only the screw hole needs to be aligned, so that the after-sale installation difficulty is greatly reduced.
The side of the motor fixing clip 115 of the motor frame 1, which is far away from the connecting portion 12, is provided with a hanging lug 111 used for being matched with the first notch 21 of the holding bar 2, and the side of the motor fixing clip 115, which is near to the connecting portion 12, is provided with a limiting fixing portion 112 used for being positioned and fixed with the second notch 22 of the holding bar 2. Fig. 3b is an enlarged structural schematic view of a motor frame hanger according to an embodiment of the invention. As shown in fig. 3b, the shape of the hanging lug 111 can be designed to be a barb type, so that the hanging lug can be effectively prevented from being easily dropped when being hung on a motor. Specifically, the hanging lug 111 is substantially L-shaped, a first side 1111 of the L-shape is perpendicularly connected to the supporting portion 11 of the motor frame 1, and a second side 1112 of the L-shape extends in a direction away from the motor fixing clip 115 of the motor frame 1, so that the stable fixing of the holding bar 2 and the motor frame 1 is realized.
In this embodiment, the horizontal position of the hanging lug 111 is lower than that of the limiting fixing portion 112, and the L-shaped second edge 1112 extends downward in a direction away from the motor fixing clip 115 of the motor frame 1. It is understood that, in other embodiments, the horizontal position of the hanging lug 111 may also be higher than that of the limit fixing portion, and the L-shaped second edge 1112 extends upward and away from the motor fixing clip 115 of the motor rack 1.
Furthermore, a guide part 1113 is arranged at an end part of the second edge 1112 of the structure of the hanging lug 111, which is far away from the motor fixing clamping position 115, and the width of the guide part 1113 is smaller than the width of the second edge 1112, which is close to the motor fixing clamping position 115, so that the hanging lug 111 can be conveniently clamped with the first notch 21 of the holding strap 2 when the holding strap 2 is installed. Preferably, the guide part 1113 is connected with a part close to the second edge 1112 of the motor fixing clamp position 115 through a bevel edge, so that two parts with different widths can be smoothly transited, and the mounting process of the holding bar is smoother.
In order to fix the clasp 2, a slot can be formed between the first side 1111 and the second side 1112 of the hanging ear 111 and the supporting portion 11 of the motor frame 1 to match with the first notch 21 of the clasp 2. Furthermore, in order to prevent the notch of the holding bar 2 from being easily separated from the clamping groove, a protrusion 1114 is further arranged on one side of the clamping groove far away from the motor fixing clamping position 115. Therefore, when the clasp 2 is separated from the structure of the hanging lug 111, the protrusion 1114 can play a certain blocking role, so that the clasp 2 cannot be easily separated from the hanging lug 111, and the clasp is further ensured to be installed without being separated through external force.
Furthermore, the slot at the matching position of the first notch 21 on the hanging lug 111 of the motor rack 1 is approximately rectangular, the length of the side edge of the slot along the first edge 1111 direction of the L-shaped hanging lug 111 is C1, and the length of the bottom edge along the direction of the supporting part 11 of the motor rack 1 is C2. When the clip is installed, in order to prevent the clip 2 from interfering with the hanging lug 111, the clip 2 rotates with the contact edge of the first notch 21 and the hanging lug 111, and the installation position is adjusted, so that C2 is more than or equal to C1 and more than C3, wherein C3 is the external material width of the first notch 21 of the clip 2, namely the maximum material thickness of the clip at the first notch. Through setting up C1 > C3 to guarantee the size of draw-in groove and can make the first breach 21 of holding up the book 2 smoothly pass through, carry out the block.
In addition, in order to reduce stress concentration and increase the stability of the hanging lug 111, the back of the hanging lug 111 is provided with a fillet, i.e. a fillet structure R is arranged at the joint of the first edge 1111 of the hanging lug 111 close to the motor fixing clamping position 115 and the supporting part 11 of the motor frame 1. Wherein the value of R is 2.5-3.5 mm. Preferably, R is 3 mm. When the fillet is too small, the optimization effect of reducing stress concentration is not good. When the fillet is too large, the fillet part and the holding piece 2 interfere with each other, so that abnormal installation is caused.
Referring to fig. 3a again, the limit fixing portion 112 is disposed on the side of the motor fixing clip 115 of the motor rack 1 close to the connecting portion 12, and includes a first fixing plate 1121 and a limit flange 1122. The first fixing plate 1121 is perpendicular to the supporting portion 11, is disposed on one side of the supporting portion away from the motor 3, and is provided thereon with a first screw hole 1123 for being fixed to the holding bar 2 by a screw 4. The limit flange 1122 is provided on the first fixing plate 1121, and extends in parallel thereto, while further extending away from the motor 3.
Fig. 3c is an enlarged schematic structural view of the motor frame limiting fixing portion according to the embodiment of the present invention. As shown in fig. 3c, the limit flange 1122 is provided on the limit fixing portion 112 of the motor rack 1, the limit flange 1122 is T-shaped, the vertical side of the T-shaped lower portion is connected to the first fixing plate 1121, the horizontal side of the upper portion is away from the first fixing plate 1121, and the second notch 22 of the tab 2 is correspondingly provided. When the two are installed in a matched mode, the positioning function is achieved, the holding piece 2 cannot fall off when being preassembled, and the installation efficiency is improved.
The length of the second notch 22 is L1, the width of the vertical edge of the lower portion of the T-shaped retaining flange 1122 is L2, and the difference Δ L between L1 and L2 is 3.5-4.5 mm. Preferably, the difference Δ L between L1 and L2 is 4mm, ensuring a gap of 2mm around the second notch 22. When the gap is too large, the positioning is inaccurate, the position deviation of the upper screw hole and the lower screw hole is large, and the fixing screw is not easy to fix; when the clearance is too small, the clamping can be carried out only by accurately positioning the two, and the installation difficulty can be increased.
Fig. 4a is a schematic structural diagram of a clasp according to an embodiment of the invention. As shown in fig. 4a, the clasp 2 comprises a clasp body 23 and a second fixing plate 25 connected thereto. In this embodiment, the holding bar body 23 includes an arc section and a flat plate section connected to a first end of the arc section, and a second end of the arc section is connected to the second fixing plate 25. In this embodiment, a central angle corresponding to the circular arc segment is smaller than a predetermined angle, and the flat plate segment is disposed along a tangential direction of the circular arc segment, where the predetermined angle is 150 ° to 180 °. Through improving the shape of holding the scale body, cooperation hangers and limit flange's structure setting has changed the atress direction when holding the scale and being connected with the supporting part, has increased the block power that the block structure of holding the scale and motor frame received at the component of horizontal direction, simultaneously because limit flange's direction setting for a plurality of angles of holding the scale and motor frame at the horizontal direction receive the block power effect, thereby hold the scale difficult droing during making the installation, and easy to assemble and adjustment hold the scale.
Fig. 4b is a schematic structural diagram of the connection between the climbing pole and the motor frame according to the embodiment of the present invention. As shown in fig. 4b, the arc segment of the main body of the climbing bar 2 is opposite to the arc-shaped motor fixing clip 115 of the motor frame 1, and is used for clamping the cylindrical motor 3 fixing part therebetween.
