[0037] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples.

[0038] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0039] Hereinafter, with reference to the accompanying drawings, a chassis assembly 1000 according to an embodiment of the first aspect of the present invention will be described.

[0040] like Figure 1 、 Figure 4 and Figure 5 As shown, the chassis assembly 1000 includes a chassis 100, a first fan volute 200, a second fan volute 300 and a connecting member 400, the first fan volute 200 includes a first volute 210, the first volute 210 participates in defining a first air duct cavity 220 of the first fan volute 200, the second fan volute 300 includes a second volute 310, the second volute 310 participates in defining a second air duct cavity 320 of the second fan volute 300, and the second volute 310 and the first volute 210 are connected in a first direction (for example, Figure 1 The first volute 210 and the second volute 310 are respectively provided with a first matching portion 230, and the first matching portion 230 and the chassis 100 are at least in the second direction (eg Figure 4 The upper limit position cooperates with the first volute 210 and the second volute 310 to limit the movement of the first volute 210 and the second volute 310 relative to the chassis 100 in at least the second direction. The connecting member 400 is integrally connected between the first volute 210 and the second volute 310. For example, the first volute 210, the second volute 310 and the connecting member 400 are an integrally formed part; the connecting member 400 has a second matching portion 410, and the second matching portion 410 is aligned with the chassis 100 in the first direction and the third direction (for example Figure 1 CC' direction) upper limit cooperates to limit the movement of the connecting member 400 relative to the chassis 100 in the first direction and the third direction, the first direction intersecting the third direction and both being perpendicular to the second direction.

[0041] It can be understood that the first matching portion 230 and the chassis 100 can only be matched in the second direction, or the first matching portion 230 and the chassis 100 can not only be matched in the second direction but also be positioned in at least one of the first direction and the third direction; but it is not limited to this.

[0042] It can be seen that when the chassis assembly 1000 is assembled, the first matching portion 230 and the chassis 100 are matched in at least the second direction, the second matching portion 410 and the chassis 100 are matched in the first direction and the third direction, and the connecting member 400 connects the first volute 210 and the second volute 310, then the first volute 210 can be installed on the chassis 100 through the first matching portion 230 thereon and the second matching portion 410 on the connecting member 400, and similarly, the second volute 210 can also be installed on the chassis 100 through the first matching portion 230 thereon and the second matching portion 410 on the connecting member 400. The limiting directions of the first matching portion 230 and the second matching portion 410 are different, so that the first volute 210 and the second volute 310 can be reliably installed on the chassis 100, so that the structure composed of the first volute 210, the second volute 310 and the connecting member 400 can be reliably assembled with the chassis 100.

[0043] Therefore, in the above-mentioned setting of the embodiment of the present application, the first volute 210 and the second volute 310 can share the second matching portion 410 on the connecting member 400 to realize assembly with the chassis 100, which is convenient for reducing the number of structures on the first volute 210 and the second volute 310 that match with the chassis 100 while ensuring reliable installation of the first volute 210 and the second volute 310. For example, it is helpful to reduce the number of first matching portions 230 on both the first volute 210 and the second volute 310, so as to simplify the structure of the first volute 210 and the second volute 310. At the same time, since the first volute 210 and the second volute 310 can share the second matching portion 410, the second matching portion 410 can be "used for multiple purposes", which is helpful to reduce the number of second matching portions 410.

[0044] In addition, since the connecting member 400 is integrally connected between the first volute 210 and the second volute 310, it is beneficial to enhance the rigidity of the overall structure composed of the first volute 210, the second volute 310 and the connecting member 400. Compared with the way in which the first volute and the second volute are not connected and are separately installed on the chassis in some technologies, the above-mentioned setting can reduce the number of independent components. During the assembly process of the chassis assembly 1000, the overall structure composed of the first volute 210, the second volute 310 and the connecting member 400 is assembled with the chassis 100, which is beneficial to saving the assembly process between the first volute 210 and the connecting member 400, saving the assembly process between the second volute 310 and the connecting member 400, and facilitating processing.

[0045] It can be understood that in the description of this application, "limiting fit" can be understood as the generation of an interaction force between the first feature and the second feature, that is, the first feature generates a force on the second feature to limit the second feature to achieve a limiting effect. For example, the first feature and the second feature can be magnetically fitted, snap-fitted (for example, the buckle 110 on the chassis 100 is snap-fitted with the first fitting part 230), or threadedly connected, etc.

[0046] According to the chassis assembly 100 of the embodiment of the present utility model, the first volute 210 and the second volute 310 are provided to be limitedly engaged with the chassis 100 through the first matching portion 230 thereon, and the connecting piece 400 integrally connected between the first volute 210 and the second volute 310 is limitedly engaged with the chassis 100 through the second matching portion 410 thereon, so that the first volute 210 and the second volute 310 can be reliably installed on the chassis 100, and it is beneficial to reduce the number of the first matching portion 230 and the second matching portion 410, thereby simplifying the structure of the chassis assembly 100 and improving the assembly efficiency to a certain extent.

[0047] Compared with some technologies, the first volute and the second volute are spaced apart and are installed on the chassis separately and in sequence, so the number of the matching parts for limiting the first volute and the second volute is large, and usually the first volute and the second volute need to be fixed to the chassis by screws respectively, and the number of screws required is also large, which makes the assembly efficiency of the chassis assembly low and the production efficiency low. In the embodiment of the present application, a connecting piece 400 integrally connected between the first volute 210 and the second volute 310 is provided. Since the first volute 210 and the second volute 310 can be indirectly matched with the chassis 100 through the connecting piece 400, the number of the matching parts for limiting the first volute 210 and the second volute 310 can be reduced. 10 and the number of mating parts required for the second volute 310 are conducive to simplifying the structure and improving assembly efficiency; moreover, if the first volute 210 and the second volute 310 need to be fixed to the chassis 100 by fasteners (it can be understood that the fasteners can directly fix the connecting member 400 to the chassis 100, or the fasteners can indirectly fix the connecting member 400 to the chassis 100 through other components such as the mounting bracket 500 described later), the fasteners can be passed through the connecting member 400 and the chassis 100, so that the first volute 210 and the second volute 310 can also share the fasteners, saving the number of fasteners and improving assembly efficiency.

[0048] In some embodiments, as Figure 1 and Figure 2As shown, a latch hole 231 is formed on the first matching portion 230, and a latch 110 is provided on the chassis 100. The latch 110 is latched in the latch hole 231. During assembly, the latch 110 and the latch hole 231 are squeezed and deformed until the latch 110 abuts against the edge of the latch hole 231, thereby limiting the first matching portion 230 and the chassis 100 in at least the second direction, facilitating a stable connection between the two. This design not only simplifies the assembly process, but also ensures the reliability of the connection and improves the stability of the overall structure. And / or, Figure 4 and Figure 5 As shown, the second matching portion 410 is formed as a limiting hole 411, and the chassis 100 has a limiting column 120 that matches the limiting hole 411. The cross-sectional shape of the limiting column 120 is non-circular, and the cross-sectional shape of the limiting hole 411 is the same as the cross-sectional shape of the limiting column 120. The limiting column 120 can extend along the second direction to match with the limiting hole 411 and simultaneously realize the limitation of the second matching portion 410 and the chassis 100 in the first direction and the third direction. The design with a non-circular cross-section has an anti-rotation feature, which can prevent the connecting part 400 from rotating in the limiting hole 411, facilitates the rapid alignment of the first matching portion 230 and the corresponding position of the chassis 100, is conducive to improving the positioning accuracy, and ensures that the positioning of the connecting part 400 relative to the chassis 100 is more stable.

[0049] It is understood that the limiting hole 411 can be a through hole or a blind hole; the cross-sectional shape of the limiting post 120 can be semicircular, rectangular, elliptical, or hexagonal, etc. Of course, the cross-sectional shape of the limiting post 120 can also be circular, and can also achieve limiting engagement with the second mating portion 410 in both the first and third directions.

[0050] In some embodiments, as Figure 1 and Figure 6 As shown, the first matching portion 230 on the first volute 210 is located on a side away from the second volute 310, and the first matching portion 230 on the second volute 310 is located on a side away from the first volute 210. This design allows the first volute 210 and the second volute 310 to be limitedly matched with the chassis 100 on the side away from each other. Combined with the design that the second matching portion 410 is located between the first volute 210 and the second volute 310, a stable connection between the two sides of the structure composed of the first volute 210, the second volute 310 and the connecting member 400 and the chassis 100 is achieved. In this way, the first volute 210 and the second volute 310 can better disperse the load during installation, thereby ensuring that the entire first volute 210 and the entire second volute 310 are reliably installed on the chassis 100, which is beneficial to improving the stability of the overall structure.

[0051] In some embodiments, as Figure 1 、 Figure 5 and Figure 6As shown, a first air outlet 130 connected to the first air duct cavity 220 and a second air outlet 140 connected to the second air duct cavity 320 are formed on the chassis 100, and the first air outlet 130 and the second air outlet 140 are arranged at intervals; the first fan volute 200 also includes a third volute 240, and the third volute 240 is arranged on the side of the first volute 210 away from the chassis 100, and the third volute 240 cooperates with the first volute 210 to define the first air duct cavity 220, and the second fan volute 300 also includes a fourth volute 330, and the fourth volute 330 is arranged on the side of the second volute 310 away from the chassis 100, and the fourth volute 330 cooperates with the second volute 310 to define the second air duct cavity 320. This design allows each fan volute to define its own air duct cavity through the cooperation of the two volutes, and the spacing of the first air outlet 130 and the second air outlet 140 on the chassis 100 can achieve independent air discharge from the two air duct cavities, which is beneficial for increasing the air output of the air conditioner and facilitating the improvement of the applicability of the air conditioner 200. At the same time, the arrangement of the third volute 240 and the fourth volute 330 does not easily affect the assembly of the first volute 210 and the second volute 310 with the chassis 100. For example, the structure consisting of the first volute 210, the second volute 310 and the connector 400 can be first installed on the chassis 100, and then the third volute 240 can be matched with the first volute 210 and the fourth volute 330 can be matched with the second volute 310. It can be understood that the first air outlet 130 and the second air outlet 140 can be only the air outlets corresponding to the air duct cavity, rather than the air outlets of the air conditioner, or the first air outlet 130 and the second air outlet 140 can also be the air outlets directly facing the user, in which case the first air outlet 130 and the second air outlet 140 are the air outlets of the air conditioner.

[0052] In some embodiments, as Figure 1 、 Figure 3 and Figure 9 As shown, the chassis assembly 1000 also includes a mounting bracket 500, which is used to install the motor. The mounting bracket 500 is arranged between the first fan volute 200 and the second fan volute 300, and the mounting bracket 500 is opposite to the connecting member 400. The mounting bracket 500 is formed with a first connecting hole 510 and a second connecting hole 520. The first connecting hole 510 is provided with a first fastener to fix the mounting bracket 500 to the chassis 100, and the second connecting hole 520 is provided with a second fastener to fix the mounting bracket 500 to the connecting member 400.

[0053] As can be seen, the mounting bracket 500 is located between the first fan volute 200 and the second fan volute 300 and opposite the connecting member 400, so that the motor is located between the first fan volute 200 and the second fan volute 300 to drive the corresponding wind wheel to rotate. It is understood that there can be one or more motors. The mounting bracket 500 is fixed to the chassis 100 via a first fastener and fixed to the connecting member 400 via a second fastener. This design ensures a stable connection of the mounting bracket 500 and facilitates the connection of the mounting bracket 500, the connecting member 400 and the chassis 100 into an integrated structure. At the same time, the connecting member 400 can be indirectly fixed to the chassis 100 via the mounting bracket 500, which helps to reduce the requirements for the load-bearing capacity of the first mating portion 230 and the second mating portion 410. In addition, the first and second volutes 210 and 310 can share the first fastener on the mounting bracket 500 to be fixed to the chassis 100, which saves the number of first fasteners required to fix the first and second volutes 210 and 310 to the chassis 100.

[0054] Optionally, the first fastener and the second fastener are configured to make the mounting bracket 500 detachable. For example, the first fastener and the second fastener are both threaded fasteners (such as screws), which makes the installation and disassembly of the mounting bracket 500 more convenient, facilitates subsequent maintenance and inspection, and makes the overall structure more compact, saving space.

[0055] In some embodiments, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 9 As shown, the second matching portion 410 is formed as a limiting hole 411, and the limiting hole 411 is constructed as a through hole. The chassis 100 has a limiting column 120 that matches the limiting hole 411. The limiting column 120 extends through the limiting hole 411 to the side of the connecting member 400 facing the mounting bracket 500, and the limiting column 120 and the mounting bracket 500 are fixed by a first fastener. It can be seen that the limiting column 120 is limited by the connecting member 400 through the through hole, and the first fastener ensures a stable connection between the mounting bracket 500 and the chassis 100. At the same time, the setting of the first fastener is not easy to exceed the outer contour of the connecting member 400, which is conducive to breaking the restriction of the first fastener on the mounting bracket 500, and saving the space occupied by the mounting bracket 500 on the premise that the mounting bracket 500 can achieve reliable installation of the motor, making the overall structure more compact, and saving the overall structural space; in addition, the limiting column 120 extends through the through hole to the side of the connecting member 400 facing the mounting bracket 500, so that the first fastener is directly passed through the mounting bracket 500 and the limiting column 120, which is convenient for installation.

[0056] Of course, in other embodiments of the present application, the position on the chassis 100 for installing the first fastener is not limited to the limiting column 120. For example, the first fastener can also be arranged at intervals on the outer peripheral side of the connecting member 400.

[0057] In some embodiments, as Figure 1 、 Figure 3 、 Figure 4 and Figure 9 As shown, the chassis 100 and / or the connecting member 400 abuts against the side of the mounting bracket 500 facing the connecting member 400, providing stable support for the mounting bracket 500 and improving the stability of the overall structure.

[0058] The chassis 100 includes a positioning buckle 150, which is positioned away from the connector 400 and is buckled onto the side of the mounting bracket 500 facing away from the connector 400. The design of the positioning buckle 150 ensures a secure fit between the mounting bracket 500 and the chassis 100. When the motor bracket is first assembled, the positioning buckle 150 serves as a pre-positioning mechanism and prevents the mounting bracket 500 from tipping over, enhancing assembly convenience. Furthermore, the positioning buckle 150 is positioned away from the connector 400, ensuring that the connector 400 does not affect the fit between the positioning buckle 150 and the mounting bracket 500.

[0059] In some embodiments, as Figure 3 、 Figure 4 、 Figure 5 and Figure 9 As shown, the positioning buckle 150 is disposed on the outer periphery of the connector 400, achieving a clearance arrangement between the positioning buckle 150 and the connector 400. The edge of the mounting bracket 500 has a stop flange 530 extending away from the connector 400, and the positioning buckle 150 is secured to the stop flange 530. This design allows the positioning buckle 150 to fit tightly with the stop flange 530, facilitating positioning and coordination during assembly, and ensuring a secure connection between the mounting bracket 500 and the connector 400. Furthermore, the stop flange 530 increases the thickness of the mounting bracket 500 edge, enhancing structural strength and making the overall structure more stable.

[0060] In some embodiments, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 9As shown, the mounting bracket 500 and the connecting member 400 are positioned and matched in the first direction by the first positioning structure 600, and the mounting bracket 500 and the connecting member 400 are positioned and matched in the third direction by the second positioning structure 700. The positioning of the mounting bracket 500 and the connecting member 400 in the first direction and the third direction are respectively achieved by different positioning structures, which is conducive to simplifying the structure of the first positioning structure 600 and the second positioning structure 700, facilitating assembly, and the mounting bracket 500 and the connecting member 400 are reliably positioned.

[0061] The first positioning structure 600 includes a first positioning hole 620 and a first positioning protrusion 610 matched with the first positioning hole 620, and the second positioning structure 700 includes a second positioning hole 720 and a second positioning protrusion 710 matched with the second positioning hole 720. Therefore, the first positioning structure 600 and the second positioning structure 700 are simple in structure and easy to assemble.

[0062] It can be understood that there is no specific restriction on the shape of the first positioning protrusion 610 and the second positioning protrusion 710, and they can be T-shaped, square or other shapes, as long as positioning can be achieved, and can be adjusted according to actual needs; for example, the first positioning protrusion 610 is a T-shaped protrusion and includes a horizontal rib A and a vertical rib B. The horizontal rib A extends along the first direction and its two ends in the first direction respectively stop against the corresponding wall surfaces of the first positioning hole 620, and the vertical rib B extends along the third direction and is connected to the horizontal rib. The vertical rib B can disperse the stress concentration area, improve the fatigue resistance of the structure, and increase the structural strength; the second positioning hole 720 is sleeved on the second positioning protrusion 710, and the second positioning protrusion 710 cooperates with the second positioning hole 720 in the upper limit position in the third direction, so that the positioning between the mounting bracket 500 and the connecting member 400 is more stable and reliable, reduces the friction and wear caused by position offset, and improves the service life of the product. The positions of the first positioning protrusion 610 and the first positioning hole 620 are also not specifically limited. For example, the first positioning protrusion 610 can be located on the mounting bracket 500 and the first positioning hole 620 can be located on the connector 400, or the first positioning protrusion 610 can be located on the connector 400 and the first positioning hole 620 can be located on the mounting bracket 500. This does not affect the positioning and mating of the mounting bracket 500 and the connector 400 in the first direction via the first positioning structure 600. The positions of the second positioning protrusion 710 and the second positioning hole 720 are also not specifically limited. For example, the second positioning protrusion 710 can be located on the mounting bracket 500 and the second positioning hole 720 can be located on the connector 400, or the second positioning protrusion 710 can be located on the connector 400 and the second positioning hole 720 can be located on the mounting bracket 500. This does not affect the positioning and mating of the mounting bracket 500 and the connector 400 in the third direction via the second positioning structure 700. This design allows for flexible selection of the specific form and position of the positioning structure based on actual conditions to meet different needs and requirements.

[0063] In some embodiments, as Figure 3 and Figure 6 As shown, a second positioning protrusion 710 is formed on the connector 400, and the free end of the second positioning protrusion 710 has a flange portion 711. The flange portion 711 is located on the side of the mounting bracket 500 facing away from the connector 400, and the flange portion 711 is opposite to the portion surrounding the second positioning hole 720. When the second positioning hole 720 is engaged with the second positioning protrusion 710, the flange portion 711 can engage with the mounting bracket 500, achieving a limited engagement of the mounting bracket 500 in the second direction and ensuring a secure connection between the mounting bracket 500 and the connector 400. Alternatively, a certain distance between the flange portion 711 and the mounting bracket 500 allows for fine-tuning of the mounting bracket 500 within a certain range to accommodate different assembly requirements.
