DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0033] like Figure 1 As shown, the air conditioner is provided with a motor 300 and a centrifugal fan 200. In the related art, Figure 2 As shown, the motor 300 (not shown) and the volute of the centrifugal fan 200 are usually fixed to the middle partition 4 with bolts, and the middle partition 4 is then fixed to the chassis with multiple bolts. If one of the components is tightened too hard or too little during the bolt tightening process, or due to manufacturing deviations of the middle partition 4, the relative position of the volute will deviate. In the normal assembly state, Figure 3 As shown, the middle partition 4 is arranged vertically relative to the chassis, and the air guide ring 24 of the volute fits in with the inner ring of the wind wheel 23. Figure 4 As shown, when the middle partition 4 has a deformation of 1°, there is a certain gap between the air guide ring 24 and the inner ring of the wind wheel 23. The maximum position deviation of the gap is n. The ratio of the maximum position deviation n to the inner diameter of the wind wheel 23 can reach 1.7%, resulting in poor performance of the fan.

[0034] To solve the above problems, Figures 5 to 15 As shown, the present disclosure provides a positioning connection structure, which includes a first component 2, a second component 3, a first connecting member 11 provided on the first component 2, a second connecting member 12 provided on the second component 3, and a third connecting member 13. The first connecting member 11 and the second connecting member 12 are both limitedly matched with the third connecting member 13, and the relative positions of the first component 2 and the second component 3 are fixed.

[0035] In the positioning connection structure provided by the present invention, the first connecting member 11 is fixed on the first component 2, and the second connecting member 12 is fixed on the second component 3. The first connecting member 11 and the second connecting member 12 are both limitedly cooperated with the third connecting member 13, so that the position of the third connecting member 13 is fixed, and the positions of the first component 2 and the second component 3 relative to the third connecting member 13 are also fixed, thereby achieving the relative position fixation of the first component 2 and the second component 3, realizing the connection and fixation of the two, reducing installation errors, and improving assembly accuracy and assembly efficiency.

[0036] Here, it should be noted that the first component 2 can be a volute and the second component 3 can be a chassis. By designing the structures of the first connecting member 11, the second connecting member 12 and the third connecting member 13, the relative position of the volute and the chassis is fixed, eliminating the position offset of the volute caused by installation errors or the manufacturing deviation of the middle partition 4 itself, and can well ensure the installation position of the volute in the box body, thereby ensuring the relative position of the volute and the wind wheel, and ensuring the performance of the centrifugal fan 200. Of course, the positioning connection structure provided by the present disclosure is not limited to application in air conditioners, but can also be applied to other components that need to be fixed and connected, such as the connection between different panels of the vehicle body, and the connection between the top cover plate 5 of the air conditioner and the surrounding panels. The limiting matching method of the first connecting member 11, the second connecting member 12 and the third connecting member 13 can be a snap-on, plug-in, threaded connection, etc. The specific structure and matching method of the three can be designed according to the assembly angle when the first component 2 and the second component 3 are fixed. The following will be described in detail by fixing the relative position of the volute and the chassis as an example.

[0037] In the present disclosure, the first connecting member 11 is provided on the first mounting surface 20 of the first member 2, and the second connecting member 12 is provided on the second mounting surface 30 of the second member 3. The first connecting member 11, the second connecting member 12 and the third connecting member 13 are configured such that the first mounting surface 20 and the second mounting surface 30 are arranged vertically. Figure 2 As shown, the volute can be fixed together by a lower volute 21 and an upper volute 22 by snap fastening, and the first mounting surface 20 can be the front and rear side surfaces of the lower volute 21 in the X direction, as shown in FIG. Figure 16 and Figure 17 As shown, the first connecting member 11 can be integrally injection-molded on the first mounting surface 20, or can be fixed on the first mounting surface 20 by screws. Figure 17As shown, the second mounting surface 30 is the plane where the chassis is located. The position of the second connecting member 12 on the chassis can be pre-designed according to the position of the volute. The second connecting member 12 is detachably mounted at an appropriate position on the chassis using fasteners. In other embodiments, it can also be fixed by welding, riveting, etc. The positioning connection structure provided by the present disclosure can achieve the fixation of the relative positions between two components at a specific assembly angle. The middle partition 4 is mounted on the volute. After the positions of the volute and the chassis are fixed, the middle partition 4 can be ensured to be arranged vertically with the second mounting surface 30 of the chassis, thereby ensuring that the state of the centrifugal fan meets the design requirements. In other embodiments, the first mounting surface 20 and the second mounting surface 30 can be arranged in parallel or in the same plane. Positioning connection structures that can achieve the fixation of the first component 2 and the second component 3 all fall within the scope of protection of the present disclosure.

[0038] In the present disclosure, the first connecting member 11 has a first clamping portion 110, the second connecting member 12 has a second clamping portion 120, and the third connecting member 13 has a clamping slot 130. The first clamping portion 110 and the second clamping portion 120 can extend into and be fixed in position within the clamping slot 130. In the embodiment of the clamping and limiting fit, not only is the first component 2 and the second component 3 connected and fixed, but the two can also be easily disassembled, making it convenient to remove the volute from the chassis.

[0039] The structures of the first connecting member 11, the second connecting member 12 and the third connecting member 13 will be introduced below in conjunction with specific embodiments to achieve the fixation of the relative positions of the first component 2 and the second component 3, so as to stably fix the volute on the chassis.

[0040] In an exemplary embodiment provided by the present disclosure, Figure 6 and Figure 7 As shown, the first connecting member 11 includes a first transverse plate 111 and a first clipping plate 112. One end of the first transverse plate 111 is fixed to the first member 2, and the first clipping plate 112 is provided at the other end of the first transverse plate 111. The first clipping plate 112 forms a first clipping portion 110. The first transverse plate 111 and the first clipping plate 112 can be formed into a T-shaped structure, so that the first clipping plate 112 is clipped into and matched with the clipping slot 130. The clipping plate 112 can only slide along the length direction of the clipping slot 130 and can be limited in both the length direction and the depth direction of the clipping slot 130, thereby fixing the position of the first member 2 relative to the third connecting member 13.

[0041] In an exemplary embodiment provided by the present disclosure, Figures 8 to 10As shown, the second connecting member 12 includes a second transverse plate 121, a vertical plate 122, and a second clipping plate 123. The first end of the vertical plate 122 is mounted on the second member 3, and the second transverse plate 121 is provided at the second end of the vertical plate 122. The second transverse plate 121 and the second clipping plate 123 are arranged at an angle to each other, and the second clipping plate 123 forms a second clipping portion 120. The second clipping plate 123 and the second transverse plate 121 form a T-shaped structure, which enables the second clipping plate 123 to be snap-fitted with the slot 130. The second clipping plate 123 can only slide along the length of the slot 130 and can be limited in both the length and depth directions of the slot 130, thereby fixing the position of the second member 3 relative to the third connecting member 13. In other embodiments, the first clipping portion 110 and the second clipping portion 120 can also be snap-fitted.

[0042] To facilitate connection between the second connector 12 and the chassis, a first reinforcing plate 124 is provided at the first end of the vertical plate 122. The first reinforcing plate 124 has fastening holes 1240 defined therein. The first reinforcing plate 124 is mounted on the second member 3 via fasteners passing through the fastening holes 1240. The first reinforcing plate 124 increases the contact area with the chassis, providing a stable and detachable mounting of the second connector 12 on the chassis.

[0043] Furthermore, in the present disclosure, a second reinforcing plate 125 is provided at the end of the second transverse plate 121 opposite the engaging plate 123. A clearance fit is formed between the second reinforcing plate 125 and the first mounting surface 20 of the first member 2. The second reinforcing plate 125 ensures symmetry between the two sides of the vertical plate 122 and increases the structural strength of the second connector 12. When the third connector 13 is pre-engaged in the second connector 12, the second reinforcing plate 125 can be grasped for ease of operation.

[0044] In an exemplary embodiment provided by the present disclosure, Figures 11 to 13 As shown, the third connecting member 13 has a slot 130 extending along its length direction. Figure 15 As shown, the first clamping portion 110 and the second clamping portion 120 can move along the length direction in the clamping slot 130 and be limited in the width direction and depth direction. After the first clamping plate 112 and the second clamping plate 123 are installed in the clamping slot 130, the first component 2 can be stably positioned and fixed at the specified position of the second component 3 through dimensional matching.

[0045] Specifically, to achieve positional engagement between the first connector 11 and the third connector 13, in this embodiment, the first connector 11 can be designed as an L-shaped plate or a T-shaped plate. In the embodiment designed as a T-shaped plate, the slot 130 has an upper stop wall 1301 and a lower stop wall 1302, and the upper and lower sides of the first clipping plate 112 respectively engage with the upper and lower stop walls 1301 and 1302 of the slot 130. To achieve positional engagement between the second connector 12 and the third connector 13, the second clipping plate 123 extends to both sides of the second transverse plate 121 and engages with the upper and lower stop walls 1301 and 1302 of the slot 130. The shapes of the first clamping portion 110 and the second clamping portion 120 are adapted to the shape of the card slot 130. In this embodiment, they are both designed as T-shaped structures. In other embodiments, they can be designed as long card slots, long card holes, etc. The shape of the clamping portion can be adaptively adjusted.

[0046] like Figure 14 As shown, in the longitudinal direction, one end of the slot 130 is closed, and the other end forms an opening for the first and second clipping plates 112, 123 to enter the slot 130. A limiting structure is provided at the opening of the slot 130 to prevent the first and second clipping plates 112, 123 from being dislodged. In the present disclosure, the limiting structure can be a bolt threadedly connected to the inner wall of the slot 130. After the first and second clipping plates 112, 123 are installed in place, the bolt is tightened to stop them from being dislodged.

[0047] In an exemplary embodiment of the present disclosure, the limiting structure is a stopper protrusion 131 protruding from the inner wall of the slot 130, and the first and second clamping plates 112 and 123 are arranged side by side along the length direction and are limited in the length direction by the stopper protrusion 131. Figure 18 and Figure 19 As shown, the second connecting member 12 is mounted on the chassis by fasteners, and the third connecting member 13 is snap-fitted with the second connecting member 12 in advance, as shown in FIG. Figure 17 As shown, the first connecting member 11 of the volute is then inserted into the slot 130 from one side of the opening along the length direction. At this time, the third connecting member 13 is moved until the stop protrusion 131 completely passes through the first clamping plate 112, completing the locking action and achieving limited cooperation in three directions. The first connecting member 11 and the second connecting member 12 can be stably and firmly fixed in the slot 130 of the third connecting member 13, thereby fixing the relative position of the volute and the chassis.

[0048] Furthermore, by designing the dimensional matching relationship between the first connecting member 11 , the second connecting member 12 and the slot 130 , positioning in the length direction, the width direction and the depth direction is achieved.

[0049] like Figure 15As shown, in the width direction, the distance between the top surface of the first horizontal plate 111 and the wall surface of the upper stop wall 1301 is c1, and the distance between the bottom surface of the first horizontal plate 111 and the wall surface of the lower stop wall 1302 is c2, wherein c1+c2<0.2mm, which can avoid movement in the width direction and achieve fixation in the width direction.

[0050] In the depth direction, the distance between the first surface of the first clamping plate 112 and the inner wall of the clamping slot 130 is b1, and the distance between the second surface of the first clamping plate 112 and the inner wall of the clamping slot 130 is b2, where b1+b2<0.1mm, which can avoid movement in the depth direction and achieve fixation in the depth direction.

[0051] In the length direction, Figure 14 As shown, the width of the gap between the first clamping plate 112 and the second clamping plate 123 is a, where a < 1 mm, so that the first clamping plate 112 and the second clamping plate 123 are arranged closely together in the length direction. A stopper protrusion 131 is used to limit the position at one end of the opening. In this embodiment, the stopper protrusion 131 can be a protruding hemispherical structure with a height of h. In the depth direction, h>b1+b2, which can ensure that the second clamping plate 123 does not pass over the stopper protrusion 131, acting as a stop. Multiple stopper protrusions 131 can be arranged at intervals along the width direction, and the specific number is not limited.

[0052] Further, if Figure 11 、 Figure 12 and Figure 19 As shown, the stop protrusion 131 is provided at the bottom of the slot 130, and a notch 132 is provided at a position of the slot 130 corresponding to the stop protrusion 131. When installing the first connecting member 11, in order to avoid interference caused by the stop protrusion 131, it is possible to make way at the notch 132 to ensure that the first connecting member 11 can smoothly enter the slot 130.

[0053] According to a second aspect of the present disclosure, an air conditioner is provided, which includes the positioning connection structure described above. The air conditioner has all the beneficial effects of the positioning connection structure described above, and no further details are given here.

[0054] During assembly, the second connecting member 12 is fixed to the chassis by fasteners, and the third connecting member 13 is inserted in advance, and the second clamping plate 123 of the second connecting member 12 is inserted into the clamping slot 130 in advance, so as to achieve the following Figure 19The state shown. Fix the volute to the middle partition 4, then snap-fit ​​the first connecting member 11 on the volute with the third connecting member 13, that is, snap the first snap-in plate 112 into the snap-in groove 130, and at this time move the third connecting member 13 in the direction away from the middle partition 4 until the stop protrusion 131 completely passes through the first snap-in plate 112, thus completing the locking action and stably fixing the volute on the chassis, which can well ensure that the installation position of the volute in the box is fixed, thereby ensuring the relative position of the volute and the wind wheel 23 is fixed, and ensuring that the fan state does not deviate from the design.

[0055] In the present disclosure, in the positioning connection structure introduced above, there are two first connecting members 11, second connecting members 12 and third connecting members 13 respectively. The two first connecting members 11 can be respectively arranged on the front and rear sides of the lower volute 21 in the X direction, and the two second connecting members 12 are arranged at intervals on the chassis. The positions of the two third connecting members 13 depend on the positions of the first connecting members 11 and the second connecting members 12, so as to stably fix the volute on the chassis. Regarding the number of the three connecting members in the positioning connection structure, the present disclosure does not limit it.

[0056] In the foregoing detailed description, reference is made to the accompanying drawings, which illustrate, by way of illustration, specific aspects of the present disclosure in which it may be practiced. In this regard, terms indicating directions or expressing positional relationships, such as "center," "longitudinal," "lateral," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc., may be used with reference to the orientation of the figures being described. Since the components of the described devices may be positioned in a plurality of different orientations, the directional terms may be used for illustrative purposes rather than restrictive. It should be understood that other aspects may be utilized and structural or logical changes may be made without departing from the concepts of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0057] It should be understood that, unless otherwise specifically noted, the features of the various embodiments of the present disclosure described herein may be combined with each other. As used herein, the term "and / or" includes any one of the relevant listed items and any combination of any two or more thereof; similarly, "at least one of" includes any one of the relevant listed items and any combination of any two or more thereof.

[0058] It should be understood that, unless otherwise expressly specified or limited, the terms "join," "attach," "install," "connect," "connect," "fix," etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected, electrically connected, or communicable with each other; they can be directly connected, or indirectly connected through an intermediate medium, and they can be internally connected between two elements or an interactive relationship between two elements, unless otherwise expressly limited. For those skilled in the art, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0059] Additionally, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may be used herein to mean that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or material layer. However, the term "over" as used in reference to a component, element, or material layer being formed "over" or located "over" a surface may alternatively have a specific meaning: the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0060] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or sections, these components, parts, regions, layers or sections are not limited to these terms. On the contrary, these terms are only used to distinguish one component, part, region, layer or section from another component, part, region, layer or section. Therefore, without departing from the teachings of each example, the first component, part, region, layer or section mentioned in the examples described herein may also be referred to as the second component, part, region, layer or section. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" can explicitly or implicitly include at least one such feature. In the description herein, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0061] It should be understood that spatially relative terms, such as "above," "upper," "below," and "lower," are used herein to describe the relationship of one element to another element shown in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" encompasses both above and below orientations, depending on the spatial orientation of the device. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0062] Furthermore, the word "exemplary" is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the use of the word exemplary is intended to present concepts in a concrete manner. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or." That is, unless otherwise specified or clear from the context, "X applies to A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies to A; X applies to B; or X applies to both A and B, then "X applies to A or B" satisfies any of the aforementioned instances. Furthermore, the articles "a" and "an," as used in this application and the appended claims, are generally understood to mean "one or more," unless otherwise specified or clear from the context to refer to the singular form.

[0063] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the accompanying drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims.
