Referring now to the drawings, an air duct assembly 100 according to an embodiment of the present invention will be described.

As shown in fig. 1 and 2, an air duct assembly 100 according to an embodiment of the present invention includes a volute 1 and a motor 2, the volute 1 includes an air duct portion 11 and a bracket portion 12, the air duct portion 11 may be formed substantially in a cylindrical structure, the air duct portion 11 defines an air supply duct 110, and an air flow may flow in the air supply duct 110, so that the air duct assembly 100 may supply air through the air supply duct 110; the radial inboard of wind channel portion 11 is located to stake frame portion 12, then stake frame portion 12 is located the inboard of the air supply wind channel 110 in the outward flange of the orthographic projection of predetermineeing on the projection face in the orthographic projection of predetermineeing on the projection face, circumference one side of stake frame portion 12 is formed with installation cavity 120, motor 2 installs in installation cavity 120, and the open setting of axial one end of installation cavity 120, then motor 2 can cooperate in installation cavity 120 from the open side of installation cavity 120, be favorable to promoting the packaging efficiency of motor 2 and stake frame portion 12.

Wherein, the predetermined projection plane is perpendicular to the central axis of the mounting cavity 120. It should be noted that, in the description of the present application, the axial direction of the mounting cavity 120 may be understood as the axial direction of the air channel portion 11, the central axis of the mounting cavity 120 may coincide with the central axis of the air channel portion 11, or the central axis of the mounting cavity 120 may be disposed offset from the central axis of the air channel portion 11.

Wherein, the perisporium of installation cavity 120 is formed with first spacing portion 120a, the periphery wall 20 of motor 2 has the spacing portion 2a of second, the spacing portion 2a of second cooperates with first spacing portion 120a in order to restrict the ascending rotation of motor 2 in the circumference of installation cavity 120, motor 2 can not take place great rotation relatively to support portion 12 in the circumference of installation cavity 120 basically promptly, thereby realize motor 2 spacing in the circumference of installation cavity 120, in order to avoid motor 2 to cooperate and take place great rotation and lead to the follow-up installation of motor 2 to fix loaded down with trivial details for installation cavity 120 after the installation cavity 120.

It can be seen that, when the motor 2 is fitted to the mounting cavity 120, the motor 2 can be pre-positioned in the circumferential direction of the mounting cavity 120 through the fitting of the first limiting portion 120a and the second limiting portion 2a, and in the subsequent installation and fixation process of the motor 2, the motor 2 does not need to be circumferentially limited, so that the subsequent installation and fixation of the motor 2 are facilitated. The degree of tightness of the fit between the first limiting part 120a and the second limiting part 2a can be set according to actual requirements, or the degree of circumferential limitation of the motor 2 by the first limiting part 120a can be set according to actual requirements; for example, after the first limiting portion 120a and the second limiting portion 2a are engaged, the motor 2 does not rotate relative to the mounting cavity 120 in the circumferential direction of the mounting cavity 120, or the motor 2 allows a small rotation (for example, the rotation does not exceed 10 ° or the like) relative to the mounting cavity 120 in the circumferential direction of the mounting cavity 120.

It is understood that during the installation of the motor 2, the circumferential wall of the installation cavity 120 may carry the motor 2 to limit the movement of the motor 2 in the radial direction of the installation cavity 120 to achieve the radial limitation of the motor 2.

According to the air duct assembly 100 of the embodiment of the utility model, the first limiting portion 120a is arranged on the peripheral wall of the mounting cavity 120, the second limiting portion 2a is arranged on the peripheral wall 20 of the motor 2, and the second limiting portion 2a is matched with the first limiting portion 120a to limit the rotation of the motor 2 in the circumferential direction of the mounting cavity 120, so that the limiting of the motor 2 in the circumferential direction of the mounting cavity 120 is realized, that is, the pre-limiting when the motor 2 is mounted in the mounting cavity 120 can be realized, a fixing hole (for example, a first fixing hole 2c described later) on the motor 2 is conveniently and quickly aligned with a mounting hole (for example, a second fixing hole 120c described later) on the volute 1, the assembly of the motor 2 and the volute 1 is convenient, and the assembly efficiency of the motor 2 and the volute 1 is effectively improved.

Compared with some technologies, a manual assembly post is added on a production line to realize radial limiting of the motor and the volute through hand feeling, limiting accuracy is poor, and production efficiency is limited in improvement degree and incomplete in improvement; can realize motor 2's spacing in advance fast in this application, be convenient for guarantee motor 2 spacing accuracy in advance, effectively promoted the production efficiency of wind channel subassembly 100.

Optionally, at least a part of the outer circumferential wall 20 of the motor 2 is matched with the inner circumferential wall of the mounting cavity 120, so as to ensure that the motor 2 and the mounting cavity 120 have a larger matching area, so as to ensure that the motor 2 is stably mounted.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, the first position-limiting portion 120a is a position-limiting hole 120b, the second position-limiting portion 2a is a position-limiting support lug 2b, and the position-limiting support lug 2b extends into the position-limiting hole 120b along the radial direction of the mounting cavity 120, and two side walls of the position-limiting hole 120b in the circumferential direction of the mounting cavity 120 can limit the position of the position-limiting support lug 2b in the circumferential direction of the mounting cavity 120. Therefore, the first limiting part 120a and the second limiting part 2a are simple in structure and reliable in matching.

In some embodiments of the present invention, as shown in fig. 1 and 3, the limiting hole 120b penetrates through the open end of the mounting cavity 120 in the axial direction of the mounting cavity 120, that is, the limiting hole 120b penetrates through the end surface of the open end of the mounting cavity 120, or the end surface of the open end of the mounting cavity 120 is formed with a notch, the notch is communicated with the limiting hole 120b, when the motor 2 is fitted to the mounting cavity 120, the motor 2 can be fitted to the mounting cavity 120 from the open end of the mounting cavity 120 in the axial direction of the mounting cavity 120, in this process, the limiting lug 2b is fitted to the limiting hole 120b through the notch on the open end of the mounting cavity 120, so as to realize the fitting of the limiting lug 2b and the limiting hole 120b, and facilitate the mounting of the motor 2.

Of course, the limiting hole 120b may not penetrate through the open end of the mounting cavity 120, so as to avoid the limiting lug 2b from being clamped on the wall surface of the limiting hole 120b in the mounting process of the motor 2, and to properly increase the axial length of the limiting hole 120b in the mounting cavity 120, the motor 2 may be smoothly fitted to the mounting cavity 120.

In some embodiments of the present invention, as shown in fig. 1 to fig. 3, the limiting hole 120b penetrates through the circumferential wall of the mounting cavity 120 along the radial direction of the mounting cavity 120, that is, the limiting hole 120b is formed as a through hole in the radial direction of the mounting cavity 120, so that the limiting hole 120b allows the limiting lug 2b to extend out of the mounting cavity 120 through the limiting hole 120b, which is beneficial to reducing the requirement on the radial length of the limiting lug 2b, and meanwhile, in the radial direction of the mounting cavity 120, the limiting hole 120b may be communicated with the air supply duct 110, so that the part of the motor 2 located in the mounting cavity 120 may dissipate heat through the limiting hole 120b, and the air flow in the air supply duct 110 may take away heat generated by the operation of the motor 2 in time, which is beneficial to the heat dissipation of the motor 2, and ensures the reliable operation of the motor 2.

In some embodiments of the present invention, as shown in fig. 1 to fig. 3, the limit support lug 2b is formed with a first fixing hole 2c penetrating therethrough, that is, the first fixing hole 2c is formed as a through hole, the first fixing hole 2c can penetrate through the limit support lug 2b along an axial direction of the installation cavity 120, the bracket portion 12 is formed with a second fixing hole 120c, and a fastening member is sequentially inserted through the first fixing hole 2c and the second fixing hole 120c to fixedly connect the motor 2 and the bracket portion 12, obviously, when the fastening member is installed, the fastening member is disposed on a side of the first fixing hole 2c, which is opposite to the second fixing hole 120c, and the fastening member is inserted through the first fixing hole 2c first and moves continuously to be inserted through the first fixing hole 2c and the second fixing hole 120c, so as to achieve the fixed installation of the motor 2.

It can be seen that, in the fixing process of the motor 2, the fastening member may be installed from one side of the installation cavity 120 facing the open end, that is, after the motor 2 is fitted to the installation cavity 120 through the open side of the installation cavity 120, the fastening member may be directly installed in the first fixing hole 2c and the second fixing hole 120c without turning over the scroll casing 1; for in some technologies, with motor 2 through the open side cooperation of installation cavity 120 after installation cavity 120, upset spiral case 1 wears to locate support portion 12 and motor 2 with the fastener in proper order again, the setting mode of fastener can save the upset step of spiral case 1 in the motor 2 installation in this application, simplifies motor 2's installation, further promotes motor 2 installation convenience, effectively promotes motor 2's installation effectiveness to promote the production efficiency of wind channel subassembly 100.

For example, when assembling the air duct assembly 100 in the present application on a production line, because the motor 2 can realize pre-positioning, and meanwhile, the spiral case 1 does not need to be turned over, the working time can be saved for the production line by about 12s, and the production efficiency is improved.

Wherein, first fixed orifices 2c is located the radial outside of the periphery wall 20 of motor 2, then the orthographic projection of first fixed orifices 2c on predetermineeing the projection is located the outside of the outline of the orthographic projection of periphery wall 20 of motor 2 on predetermineeing the projection, that is to say, along the axial of installation cavity 120, first fixed orifices 2c can not sheltered from to the periphery wall 20 of motor 2, thereby be convenient for operating personnel directly confirm the position of first fixed orifices 2c, and direct follow-up fixed operation, the periphery wall 20 of motor 2 can not take place to interfere with the fastener simultaneously, be convenient for guarantee that the fastener is installed smoothly.

It can be understood that, in the radial direction of the motor 2, the radial distance between the first fixing hole 2c and the central axis of the motor 2 is L1, the radial distance between any point on the portion of the outer peripheral wall 20 of the motor 2 corresponding to the first fixing hole 2c and the central axis of the motor 2 is L2, L1 > L2, and the difference between L1 and L2 can be set according to actual needs, so as to effectively ensure that the outer peripheral wall 20 of the motor 2 does not interfere with the installation of the fastener.

In addition, the second fixing hole 120c may be a blind hole or a through hole; when the second fixing hole 120c is a through hole, the second fixing hole 120c may penetrate the bracket portion 12 in the axial direction of the mounting cavity 120, and the extending direction of the first fixing hole 2c is the same as the extending direction of the second fixing hole 120 c.

Alternatively, the fastening member may be a screw, and the fastening member is screwed with at least the second fixing hole 120c to ensure that the motor 2 is reliably installed.

In some embodiments of the present invention, as shown in fig. 1 to 4, the limiting hole 120b penetrates through the circumferential wall of the mounting cavity 120 in the radial direction of the mounting cavity 120, the limiting support lug 2b extends out of the mounting cavity 120, and the first fixing hole 2c is located at the radial outer side of the mounting cavity 120, so that the space of the mounting cavity 120 occupied by the limiting support lug 2b can be saved, and it is convenient to ensure that a whole circle of the outer circumferential wall 20 of the motor 2 is matched with the circumferential wall of the mounting cavity 120, so as to effectively ensure the radial limitation of the mounting cavity 120 on the motor 2, and at the same time, to facilitate the installation of the fastening member.

It is understood that, when the limiting hole 120b penetrates the open end of the mounting cavity 120 along the axial direction of the mounting cavity 120 and the limiting hole 120b penetrates the circumferential wall of the mounting cavity 120 along the radial direction of the mounting cavity 120, the circumferential width of the portion of the limiting lug 2b extending out of the mounting cavity 120 may be smaller than, equal to, or larger than the circumferential width of the limiting hole 120 b.

Of course, in other embodiments, the first fixing hole 2c may also be located in the mounting cavity 120, and in this case, a certain space may be provided between the peripheral wall of the mounting cavity 120 and the outer peripheral wall 20 of the motor 2, so as to appropriately weaken the radial limit effect of the peripheral wall of the mounting cavity 120 on the motor 2.

It should be noted that, in the description of the present application, "a plurality" means two or more.

Of course, the present application is not limited thereto; in other embodiments, at least one first position-limiting portion 120a may further cooperate with a plurality of second position-limiting portions 2a, for example, for a single first position-limiting portion 120a, the first position-limiting portion 120a cooperates with two second position-limiting portions 2a, a side wall of one side of the first position-limiting portion 120a in the circumferential direction of the mounting cavity 120 may be used to limit forward rotation of one of the second position-limiting portions 2a in the circumferential direction of the mounting cavity 120, and a side wall of the other side of the first position-limiting portion 120a in the circumferential direction of the mounting cavity 120 may be used to limit reverse rotation of the other second position-limiting portion 2a in the circumferential direction of the mounting cavity 120, so that circumferential position limitation of the motor 2 may also be achieved when the first position-limiting portion 120a cooperates with two second position-limiting portions 2 a.

In addition, the number of the first position-limiting portions 120a may be one, and the number of the second position-limiting portions 2a is one, which is beneficial to simplifying the structure of the air duct assembly 100.

It can be understood that, when the first position-limiting portion 120a is a position-limiting hole 120b, and the second position-limiting portion 2a is a position-limiting support lug 2b, the position-limiting hole 120b is plural, the plural position-limiting holes 120b are arranged at intervals along the circumferential direction of the mounting cavity 120, and each position-limiting hole 120b is matched with one or more position-limiting support lugs 2 b.

It can be understood that the center of the orthographic projection of the base portion 121 on the preset projection plane and the center of the orthographic projection of the air supply duct 110 on the preset projection plane may be overlapped, or may be spaced apart from each other, i.e., not overlapped.

The axial end face of the base portion 121 has a rib 1211, the rib 1211 extends along a curve to define the mounting cavity 120, the rib 1211 forms a peripheral wall of the mounting cavity 120, and a free end of the rib 1211 can define an open end of the mounting cavity 120, which facilitates the processing of the mounting cavity 120.
