Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a mid-frame, outer casing, and air conditioner. Background Technology

[0002] With the development and progress of technology, air conditioning has gradually become a necessity in people's lives. Air conditioning generally includes: the indoor wall-mounted unit and the outdoor unit.

[0003] To ensure optimal operation of wall-mounted air conditioners, sensor components need to be installed inside. These sensors can track and locate the position of people in the room and automatically adjust the airflow parameters to improve the user experience.

[0004] However, the current sensing components have a small sensing range, resulting in poor performance of the wall-mounted air conditioner. Utility Model Content

[0005] This application provides a mid-frame, a housing, and an air conditioner. It can solve the problem of poor performance of existing wall-mounted air conditioners. The technical solution is as follows: On the one hand, a mid-frame is provided, including: a mid-frame body and at least two mounting boxes; The middle frame body includes: a front plate and a side plate fixedly connected to the outer edge of the front plate; the front plate and the side plate are used to form a cavity; the length direction of the front plate is parallel to a first direction; The at least two mounting boxes are arranged along the first direction within the cavity and connected to the front panel; each mounting box has a bearing cavity and a bearing surface located within the bearing cavity, the bearing surface being an inclined surface relative to the front panel and used to bear the sensing component; In this case, the bearing surfaces of two adjacent mounting boxes are distributed either back-to-back or facing each other.

[0006] Because the bearing surface of the mounting box is an inclined surface relative to the front panel, the bearing surfaces of two adjacent mounting boxes are distributed opposite to each other or facing each other. Therefore, by cooperating with the two sensing components in two adjacent mounting boxes, the 180° range in front of the air conditioner can be covered as much as possible, reducing the blind spot range when the air conditioner detects people in front of it through the sensing components, thereby improving the air conditioner's performance.

[0007] In some possible implementations, the mounting box has a first opening communicating with the bearing cavity; the side of the mounting box with the first opening is connected to the front panel. The front panel has at least two second openings corresponding to at least two of the mounting boxes, and the second openings communicate with the first openings.

[0008] In this case, the millimeter waves emitted by the radar element in the sensing assembly are emitted through the first opening and the second opening in sequence, without being blocked by the mounting box and the front panel.

[0009] In some possible implementations, the mounting box includes a support member fixed inside the support cavity, the support member having the support surface on the side facing the first opening. Here, the sensing component can be assembled onto the support member.

[0010] In some possible implementations, the supporting component includes at least one first support portion and at least one second support portion; wherein, in a direction perpendicular to the front plate, the minimum distance between the first support portion and the front plate is less than the minimum distance between the second support portion and the front plate.

[0011] Here, within the same mounting box, at least one first support and at least one second support can both support the same sensing component. Furthermore, in the direction perpendicular to the front panel, by ensuring that the minimum distance between the first support and the front panel is less than the minimum distance between the second support and the front panel, it can be guaranteed that the bearing surface used to support the sensing component is an inclined surface relative to the front panel.

[0012] In some possible implementations, the two adjacent mounting boxes are respectively: a first mounting box and a second mounting box; the first support portion in the first mounting box is closer to the second mounting box than the second support portion; the first support portion in the second mounting box is closer to the first mounting box than the second support portion.

[0013] This ensures that the bearing surface inside the first mounting box faces away from the second mounting box, and also ensures that the bearing surface inside the second mounting box faces away from the first mounting box.

[0014] In some possible implementations, the first mounting box and the second mounting box are centrally symmetrical, and the structures of the first mounting box and the second mounting box are identical. In this case, the first mounting box can be installed on the left and the second mounting box on the right, or the first mounting box can be installed on the right and the second mounting box on the left. That is, the first and second mounting boxes are no longer limited by their distribution positions, and foolproof design of the first and second mounting boxes can be achieved.

[0015] In some possible implementations, the first mounting box and the second mounting box are mirror images of each other, and the axis of symmetry between the first mounting box and the second mounting box is parallel to the width direction of the front panel.

[0016] In some possible implementations, the first support portion includes: a first support body and a first limiting member connected together; the second support portion includes: an adjacent second support body and a second limiting member; wherein the first support body and the second support body are both used to support the sensing component, and the sensing component is located between the first limiting member and the second limiting member.

[0017] Here, through the cooperation of multiple first limiting members and multiple second limiting members, the left and right sides of the sensing component on the bearing surface can be limited to ensure that the sensing component is not easily offset in the left and right directions.

[0018] In some possible implementations, the mounting box includes at least one connecting portion fixed inside the carrier cavity; wherein, after the sensing component is supported on the carrier surface, the at least one connecting portion is connected to the sensing component. The sensing component can be locked into the carrier cavity of the mounting box via the at least one connecting portion.

[0019] In some possible implementations, the connecting part includes: a snap-fit ​​member with a latch, wherein, after the sensing component is supported on the bearing surface, the snap-fit ​​member is snapped into the sensing component by the latch; Alternatively, the connecting part includes an auxiliary support column and a locking member, wherein after the sensing component is supported on the bearing surface, a portion of the sensing component is located on the auxiliary support column, and the locking member passes through an opening provided on the sensing component and connects to the auxiliary support column.

[0020] In some possible implementations, the mounting box includes: a first side plate and a second side plate distributed in the first direction, and a first connecting plate and a second connecting plate distributed in a second direction, the second direction being parallel to the width direction of the front plate body; A first opening of the mounting box is distributed between the side of the first side plate facing the front plate and the side of the second side plate facing the front plate; the side of the first side plate away from the front plate and the side of the second side plate away from the front plate are connected. In the second direction, one side of the first side plate and one side of the second side plate are both connected to the first connecting plate, and the other side of the first side plate and the other side of the second side plate are both connected to the second connecting plate. The first side plate, the second side plate, the first connecting plate, and the second connecting plate are used to form the bearing cavity.

[0021] In some possible implementations, the mounting box further includes an abutment portion fixed inside the bearing cavity; wherein, after the sensing component is supported on the bearing surface, the sensing component is located between the abutment portion and the first connecting plate.

[0022] Here, by the cooperation between the abutment part and the first connecting plate, the upper and lower sides of the sensing component on the bearing surface can be limited to ensure that the sensing component is not easily offset in the vertical direction.

[0023] In some possible implementations, the mounting box further includes: a first mounting part connected to the first connecting plate, and a second mounting part connected to the second connecting plate; wherein both the first mounting part and the second mounting part are connected to the front panel.

[0024] In some possible implementations, one of the first mounting part and the second mounting part is a snap-fit ​​mounting part, and the other is a fastening mounting part; the front plate has: a snap-fit ​​groove that mates with the snap-fit ​​mounting part, and a support column that mates with the fastening mounting part; wherein, the snap-fit ​​mounting part snaps into the front plate in the snap-fit ​​groove, and the fastening mounting part is fastened to the support column.

[0025] In some possible implementations, the angle between the bearing surface and the front panel is between 30° and 40°. In this case, there is no need to adjust the type of radar element in the sensing assembly; by cooperating with the sensing assemblies in the first and second mounting boxes, coverage of the front of the air conditioner unit can be achieved.

[0026] In some possible implementations, the sensing components include radar elements.

[0027] On the other hand, an outer shell is provided, including: a front cover, a middle frame, and a rear shell; the middle frame is the aforementioned middle frame, the front cover is connected to the front panel of the middle frame, and the rear shell is connected to the side of the middle frame opposite to the front panel.

[0028] In another aspect, an air conditioner is provided, comprising: any of the aforementioned mid-frames. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] This application provides a mid-frame that can serve as the mid-frame of an air conditioner. Here, the air conditioner can be a wall-mounted air conditioner unit installed indoors. Of course, this mid-frame can also serve as the mid-frame of other devices; this application does not limit its application to this. Please refer to... Figure 1 , Figure 1 This is a planar schematic diagram of a mid-frame on the back side according to an embodiment of this application. The mid-frame 000 may include: a mid-frame body 100 and at least two mounting boxes 200.

[0033] To see the structure of the mid-frame body 100 more clearly, please refer to... Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of a mid-frame body provided in an embodiment of this application. Figure 3 yes Figure 2 The diagram shows the structure of the mid-frame body on the other side. The mid-frame body 100 may include a front plate 110 and side plates fixedly connected to the outer edge of the front plate 110. The side plates 120 may be annular and distributed around the outer edge of the front plate 100. Thus, the front plate 110 and the side plates 120 can form a cavity O. Here, the front plate 110 may be a rectangular flat plate structure, with its length direction parallel to a first direction X and its width direction parallel to a second direction Y.

[0034] At least two mounting boxes 200 in the middle frame 000 can be arranged along the first direction X within the cavity O and connected to the front panel 100. It should be noted that the accompanying drawings in this embodiment illustrate an example where the middle frame 000 includes two mounting boxes 200. In other possible implementations, the middle frame 000 may also include more mounting boxes 200, such as three, four, or five. This embodiment does not limit this.

[0035] To see the structure of the mounting box 200 more clearly, please refer to... Figure 4 and Figure 5 , Figure 4 This is a plan view of the middle frame on the front provided in an embodiment of this application. Figure 5 This is a top cross-sectional view of a mid-frame provided in an embodiment of this application. Each mounting box 200 in the mid-frame 000 has a bearing cavity P and a bearing surface S0 located within the bearing cavity P. Here, for any mounting box 200 in the mid-frame 000, the bearing surface S0 of this mounting box 200 can be an inclined surface relative to the front panel 110, and this mounting box 200 is used to support the sensing component 010.

[0036] Specifically, the bearing surfaces S0 of two adjacent mounting boxes 200 are either opposite to each other or facing each other. That is, for two adjacent mounting boxes 200 distributed in the first direction X, when the bearing surfaces S0 of the two mounting boxes 200 are opposite to each other, the bearing surface S0 of one mounting box 200 is deflected and tilted relative to the front panel 100 in a direction away from the other mounting box 200; when the bearing surfaces S0 of the two mounting boxes 200 are facing each other, the bearing surface S0 of one mounting box 200 is deflected and tilted relative to the front panel 100 in a direction closer to the other mounting box 200.

[0037] Taking the opposite distribution of the bearing surfaces S0 of two adjacent mounting boxes 200 as an example, assuming that the two adjacent mounting boxes 200 distributed in the first direction X are: first mounting box 200a and second mounting box 200b, with first mounting box 200a located on the left and second mounting box 200b located on the right. Then, the bearing surface S0 of the first mounting box 200a can be deflected at a certain angle relative to the front plate 110 in a clockwise direction, and the angle of deflection is acute, so that the bearing surface S0 of the first mounting box 200a can face away from the second mounting box 200b; the bearing surface S0 of the second mounting box 200b can be deflected at a certain angle relative to the front plate 110 in a counterclockwise direction, and the angle of deflection is also acute, so that the bearing surface S0 of the second mounting box 200b can face away from the first mounting box 200a.

[0038] It should be noted that the sensing component 010 supported by the bearing surface S0 of the mounting box 200 can be a radar component or other types of sensing components. This application embodiment does not limit this. For example, the sensing component 010 may include: a circuit board 011, and a radar element 012 located on the circuit board 011. The circuit board 011 can be mounted on the bearing surface S0 of the mounting box 200, and the radar element 012 can be a millimeter-wave or microwave radar sensor. Taking a millimeter-wave sensor as an example, the central axis of the millimeter-wave beam emitted by the radar element 012 can be perpendicular to the circuit board 011.

[0039] In related technologies, the circuit board inside the air conditioner is parallel to the front panel of the mid-frame. This causes the central axis of the millimeter-wave beam emitted by the radar element to be perpendicular to the front panel. However, the beam range of the millimeter waves emitted by the radar element is usually small; for example, the beam angle is typically 120°. Therefore, current sensing components cannot cover a 180° area on the front of the air conditioner unit, resulting in blind spots when the air conditioner detects a person in front of it. These blind spots are located not only on the left but also on the right side of the front of the air conditioner unit, leading to poor performance.

[0040] In this embodiment, since the bearing surface S0 of the mounting box 200 is an inclined surface that is tilted relative to the front plate 110, and the bearing surfaces S0 of two adjacent mounting boxes 200 are distributed in opposite directions, the sensing range of the radar element 012 of the sensing component 010 located in one mounting box 200 can be deflected in a direction away from the other mounting box 200.

[0041] For example, such as Figure 6 As shown, Figure 6This is a schematic diagram illustrating the effect of the sensing component emitting millimeter waves according to an embodiment of this application. Assume two adjacent mounting boxes 200 are a first mounting box 200a and a second mounting box 200b, with the first mounting box 200a located on the left and the second mounting box on the right. Since the bearing surface S0 of the first mounting box 200a can be deflected at a certain angle counterclockwise relative to the front panel 110, and this angle is acute, the sensing range of the radar element 012 of the sensing component 010 within the first mounting box 200a can also be deflected at a certain angle counterclockwise, thereby reducing the blind zone on the left side of the air conditioner. Similarly, since the bearing surface S0 of the second mounting box 200b can be deflected at a certain angle clockwise relative to the front panel 110, and this angle is acute, the sensing range of the radar element 012 of the sensing component 010 within the second mounting box 200b can also be deflected at a certain angle clockwise, thereby reducing the blind zone on the right side of the air conditioner.

[0042] It should be noted that when the bearing surfaces S0 of two adjacent mounting boxes 200 are distributed facing each other, the sensing range of the radar element 012 of the sensing component 010 located in one mounting box 200 can be deflected in the direction closer to the other mounting box 200.

[0043] For example, suppose two adjacent mounting boxes 200 are a first mounting box 200a and a second mounting box 200b, with the first mounting box 200a located on the left and the second mounting box on the right. The bearing surface S0 of the first mounting box 200a can be deflected at a certain angle clockwise relative to the front panel 110, allowing the bearing surface S0 of the first mounting box 200a to deflect towards the second mounting box 200b. Therefore, the sensing range of the radar element 012 of the sensing component 010 located in the first mounting box 200a can also be deflected clockwise towards the second mounting box 200b, thereby reducing the blind spot area on the right side of the air conditioner.

[0044] The bearing surface S0 of the second mounting box 200b can be deflected at a certain angle counterclockwise relative to the front panel 110, so that the bearing surface S0 of the second mounting box 200b can be deflected in a direction closer to the first mounting box 200a. Therefore, the sensing range of the radar element 012 of the sensing component 010 located in the first mounting box 200a can also be deflected in a counterclockwise direction closer to the first mounting box 200a, thereby reducing the blind spot range on the left side of the air conditioner.

[0045] Therefore, regardless of whether the bearing surfaces S0 of two adjacent mounting boxes 200 are distributed opposite each other or facing each other, the sensing component 010 in the first mounting box 200a and the sensing component 010 in the second mounting box 200b can cover the 180° area in front of the air conditioner as much as possible through the cooperation of the sensing component 010 in the first mounting box 200a and the sensing component 010 in the second mounting box 200b. This reduces the blind spot range when the air conditioner detects people in front of it through the sensing component 010, thereby improving the performance of the air conditioner.

[0046] It should be noted that, for ease of description in the following embodiments, the following embodiments are illustrated by taking the example of two adjacent mounting boxes 200 with their bearing surfaces S0 facing away from each other.

[0047] In one possible implementation, such as Figure 6 As shown, the included angle α between the bearing surface S0 of the mounting box 200 and the surface of the front panel 110 ranges from 30° to 40°. For example, the included angle α between the bearing surface S0 of the mounting box 200 and the surface of the front panel 110 can be 35°.

[0048] In this case, there is no need to adjust the type of radar element 012 of the sensing assembly 010; that is, the beam angle of the millimeter wave emitted by the radar element 012 can still generally remain at 120°. By setting the angle α between the bearing surface S0 of the mounting box 200 and the side of the front plate 110 facing away from the side plate 120 to 35°, the circuit board 011 of the sensing assembly 010 can be rotated 35° relative to the front plate 110.

[0049] For example, for the sensing component 010 located in the first mounting box 200a on the left, the circuit board 011 of the sensing component 010 can be rotated 35° counterclockwise relative to the front panel 110, so that the beam of the millimeter wave emitted by the radar element 012 of the sensing component 010 can also be rotated 35° counterclockwise, thereby reducing or eliminating the left blind zone.

[0050] For the sensing component 010 located in the second mounting box 200b on the right, the circuit board 011 of the sensing component 010 can be rotated 35° clockwise relative to the front panel 110, so that the beam of the millimeter wave emitted by the radar element 012 of the sensing component 010 can also be rotated 35° clockwise, thereby reducing or eliminating the right blind spot.

[0051] Therefore, by cooperating with the sensing component 010 in the first mounting box 200a and the sensing component 010 in the second mounting box 200b, a 180° range of coverage on the front of the air conditioner unit can be achieved.

[0052] In some embodiments, such as Figure 7 As shown, Figure 7This is a schematic diagram of the structure of a mounting box provided in an embodiment of this application. The mounting box 200 in the middle frame 000 may have a first opening K1 communicating with the bearing cavity P. The side of the mounting box 200 with the first opening K1 may be connected to the front plate 110 in the middle frame body 100.

[0053] Please refer to Figure 8 , Figure 8 This is a plan view of the mounting box provided in this application embodiment after the sensing assembly is assembled. After the circuit board 011 in the sensing assembly 010 is supported on the bearing surface S0 of the mounting box 200, the radar element 012 is located on the side of the circuit board 011 opposite to the bearing surface S0. In this way, the millimeter waves emitted by the radar element 012 can be emitted through the first opening K1 without being blocked by the mounting box 200.

[0054] like Figure 2 and Figure 3 As shown, the front panel 010 in the middle frame body 100 may have at least two second openings K2. Each second opening K2 may communicate with the first opening K1 of the corresponding mounting box 200.

[0055] For example, each mounting box 200 in the middle frame 000 can be fixedly connected to the front panel 010 at the corresponding second opening K2. In this way, the first opening K1 of the mounting box 200 can communicate with the second opening K2 of the front panel 010. In this case, the millimeter waves emitted by the radar element 012 are emitted through the first opening K1 and the second opening K2 in sequence without being blocked by the front panel 110.

[0056] In some embodiments, such as Figure 7 As shown, the mounting box 200 may include a support component 20 fixed in the support cavity P, the support component 20 having a support surface S0 on the side facing the first opening K1.

[0057] For example, the sensing component 010 can be assembled with the support component 20, thereby fixing the sensing component 010 on the inclined support surface S0.

[0058] In some possible implementations, such as Figure 7 and Figure 8 As shown, the support component 20 inside the support cavity P may include at least one first support portion 210 and at least one second support portion 220. Here, within the same mounting box 200, at least one first support portion 210 and at least one second support portion 220 can both support the same sensing component 010.

[0059] For example, within the same mounting box 200, the first support portion 210 has a first main support surface S1 on the side facing the first opening K1, and the second support portion 220 has a second support surface S2 on the side facing the second opening K2. The first support portion 210 can support the sensing component 010 through the first main support surface S1, and the second support portion 220 can support the sensing component 010 through the second main support surface S2. Therefore, the support surface S0 located within the bearing cavity P may include: the first main support surface S1 located on the first support portion 210, and the second main support surface S2 located on the second support portion 220.

[0060] In this application, as Figure 9 As shown, Figure 9 This is a partial cross-sectional enlarged view of a mid-frame provided in an embodiment of this application. In the direction perpendicular to the front panel 110, the minimum distance d1 between the first support portion 210 and the front panel 110 is less than the minimum distance between the second support portion 220 and the front panel 100. In this case, in the direction perpendicular to the front panel 110, the first main support surface S1 of the first support portion 210 is closer to the front panel 110 than the second main support surface S2 of the second support portion 220. This ensures that the bearing surface S0 used to support the sensing component 010 is an inclined surface relative to the front panel 110.

[0061] In some embodiments, within the same mounting box 200, at least one first support portion 210 may be located on one side of the sensing component 010, and the first main support surface S1 of at least one support portion 210 may support one side of the sensing component 010; at least one second support portion 220 may be located on the other side of the sensing component 010, and the second main support surface S2 of at least one support portion 210 may support the other side of the sensing component 010.

[0062] It should be noted that there can be multiple first support parts 210 within the same mounting box 200, and multiple first support parts 210 can be arranged in a row along the second direction Y; similarly, there can be multiple second support parts 220 within the same mounting box 200, and multiple second support parts 210 can be arranged in a row along the second direction Y.

[0063] Here, the number of first support portions 210 and second support portions 220 within the mounting box 200 is set to multiple, and each first support portion 210 and each second support portion 220 can be a strip-shaped structure. Furthermore, since the mounting box 200 can be a box-shaped structure integrally injection molded using an injection molding process, the multiple first support portions 210 and multiple second support portions 220 not only improve the support effect for the sensing component 010, but also serve as reinforcing ribs for the mounting box 200, thereby increasing the overall strength of the mounting box 200.

[0064] In some embodiments, such as Figure 7 As shown, for the first support portion 210 and the second support portion 220 within the same mounting box 200, the first support portion 210 may include: a first support body 211 and a first limiting member 212 connected to each other; the second support portion 220 may include: a second support body 221 and a second limiting member 222 connected to each other.

[0065] The first support body 211 and the second support body 221 are both used to support the sensing component 010, and the sensing component 010 can be located between the first limiting member 212 and the second limiting member 222.

[0066] For example, in the first support portion 210, the first limiting member 212 is closer to the first opening K1 of the mounting box 200 relative to the first support body 211, and the side of the first support body 211 closest to the first opening K1 may have a first main support surface S1; in the second support portion 220, the second limiting member 222 is closer to the first opening K1 of the mounting box 200 relative to the second support body 221, and the side of the second support body 221 closest to the first opening K1 may have a second main support surface S2.

[0067] Thus, after the sensing component 010 is supported on the bearing surface S0 of the mounting box 200, the first support bodies 211 of each first support portion 210 and the second support bodies 221 of each second support portion 220 inside the mounting box 000 can support the sensing component 010. Furthermore, the sensing component 010 can be located between multiple first limiting members 212 of the multiple first support portions 210 and multiple second limiting members 222 of the multiple second support portions 220. That is, multiple first limiting members 212 are distributed on one side of the sensing component 010, and multiple second limiting members 222 are distributed on the other side of the sensing component 010.

[0068] Here, through the cooperation of multiple first limiting members 212 and multiple second limiting members 222, the left and right sides of the sensing component 010 on the bearing surface S0 can be limited to ensure that the sensing component 010 is not easily offset in the left and right directions.

[0069] In some embodiments, such as Figure 7 and Figure 8 As shown, the mounting box 200 further includes at least one connecting portion 230 fixed inside the bearing cavity P. After the sensing component 010 is supported on the bearing surface S0 of the mounting box 200, the at least one connecting portion 230 disposed inside the bearing cavity P of the mounting box 200 can be connected to the sensing component 010 to lock the sensing component 010 inside the bearing cavity P of the mounting box 200 through the at least one connecting portion 230.

[0070] For example, the mounting box 200 has two connecting portions 230 inside its supporting cavity P. Inside the same mounting box 200's supporting cavity P, one of these connecting portions 230 can be arranged in a row with multiple first support portions 210 in the second direction Y, and the other connecting portion 230 can be arranged in a row with multiple second support portions 220 in the second direction Y. Furthermore, in the second direction Y, one connecting portion 230 is located closer to one end of the mounting box 200, and the other connecting portion 230 is located closer to the other end of the mounting box 200.

[0071] That is, the two connecting parts 230 inside the mounting box 200 can correspond to a set of opposite diagonal parts of the sensing component 010, and after the two connecting parts 230 lock the set of opposite diagonal parts of the sensing component 010, the sensing component 010 can be fixed inside the bearing cavity P of the mounting box 200.

[0072] In this application, any one of the connecting parts 230 inside the bearing cavity P of the mounting box 200 can have various forms.

[0073] In one possible implementation, such as Figure 10 As shown, Figure 10 This is a schematic diagram of another mounting box provided in an embodiment of this application. The connecting part 230 may include a snap-fit ​​member with a snap-fit ​​231. Here, after the sensor component 010 is supported on the bearing surface S0 of the mounting box 200, the snap-fit ​​member can snap-fit ​​with the sensor component 010 through the snap-fit ​​231 to fix the sensor component 010 inside the bearing cavity P of the mounting box 200.

[0074] In another possible implementation, such as Figure 7 and Figure 8As shown, the connecting part 230 may include an auxiliary support column 232 and a locking member (not shown in the figure). After the sensor assembly 010 is supported on the bearing surface S0 of the mounting box 200, a portion of the sensor assembly 010 is located on the auxiliary support column 232, and the locking member can pass through the opening V1 provided on the sensor assembly 010 to connect with the auxiliary support column 232.

[0075] For example, the auxiliary support column 232 may have an auxiliary support surface S3, and the bearing surface S0 of the mounting box 200 may also include the auxiliary support surface S3. After the sensing component 010 is supported on the bearing surface S0 of the mounting box 200, the corner position of the mounting box 200 corresponding to this sensing component 010 may be located on the auxiliary support surface S3, and an opening V1 may be provided at the corner position of the sensing component 010. In this way, the locking member can pass through the opening V1 provided on the sensing component 010 and connect with the auxiliary support column 232, thereby fixing the sensing component 010 inside the bearing cavity P of the mounting box 200.

[0076] For example, the locking element in the connecting part 230 can be a screw, and the auxiliary support surface S3 of the auxiliary support column 232 can have a first threaded hole V2. After the sensor assembly 010 is supported on the bearing surface S0 of the mounting box 200, the first threaded hole V2 on the auxiliary support column 232 can communicate with the opening V1 provided on the sensor assembly 010. In this way, the screw can pass through the opening V1 provided on the sensor assembly 010 and be threadedly connected to the first threaded hole V2 to fix the sensor assembly 010 on the auxiliary support column 232.

[0077] It should be noted that in some possible implementations, both connecting portions 230 inside the bearing cavity P of the mounting box 200 include auxiliary support columns 232 and locking elements. In some possible implementations, one connecting portion 230 inside the bearing cavity P of the mounting box 200 includes auxiliary support columns 232 and locking elements, while the other connecting portion 230 includes a snap-fit ​​element with a latch 231. In other possible implementations, both connecting portions 230 inside the bearing cavity P of the mounting box 200 include snap-fit ​​elements with latches 231. This application embodiment does not limit this aspect.

[0078] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the mounting box 200 may include: a first side plate 201 and a second side plate 202 distributed in the first direction X, and a first connecting plate 203 and a second connecting plate 204 distributed in the second direction Y.

[0079] The first opening K1 of the mounting box 200 can be distributed between the side of the first side plate 201 facing the front plate 110 and the side of the second side plate 202 facing the front plate 110; the side of the first side plate 201 away from the front plate 110 is connected to the side of the second side plate 202 away from the front plate 110. In the second direction Y, one side of the first side plate 201 and one side of the second side plate 202 can be connected to the first connecting plate 203, and the other side of the first side plate 201 and the other side of the second side plate 202 can be connected to the second connecting plate 204. Here, the first side plate 201, the second side plate 202, the first connecting plate 203, and the second connecting plate 204 in the mounting box 200 are used to form a bearing cavity P. That is, the bearing cavity P of the mounting box 200 can be distributed between the first side plate 201 and the second side plate 202 in the first direction X, and can be distributed between the first connecting plate 203 and the second connecting plate 204 in the second direction Y.

[0080] In some possible cases, within the same mounting box 200, multiple first support portions 210 are located at least on the first side plate 201, and multiple second support portions 220 are located at least on the second side plate 202.

[0081] like Figure 9 As shown, the first side panel 201 of the mounting box 200 may include a first plate 2011 and a second plate 2012 connected to each other. The first plate 2011 is closer to the first opening K1 of the mounting box 200 than the second plate 2012. The first plate 2011 may be perpendicular to the front panel 110, and the angle between the second plate 2012 and the first plate 2011 is an obtuse angle.

[0082] The second side panel 202 of the mounting box 200 may include a third panel 2021 and a fourth panel 2022 connected to each other. The third panel 2021 is closer to the first opening K1 of the mounting box 200 than the fourth panel 2022. The side of the third panel 2021 facing away from the fourth panel 2022 can be connected to the side of the second panel 2012 facing away from the first panel 2011. Here, the fourth panel 2022 can be parallel to the front panel 110, and the angle between the fourth panel 2022 and the third panel 2021 is an obtuse angle.

[0083] In this application, after the first support body 211 of each first support portion 210 and the second support body 221 of each second support portion 220 align with the circuit board 011 in the sensing assembly 010, the circuit board 011 can be parallel to the second plate 2012. Furthermore, because both the first support body 211 and the second support body 221 have a certain height, there is a certain space between the circuit board 011 in the sensing assembly 010 and the second plate 2012. This space is used to accommodate other components disposed on the side of the circuit board 011 facing away from the radar element 012, ensuring that these components do not interfere with the second plate 2012 in the mounting box 200.

[0084] In some embodiments, the mounting box 200 further includes an abutment portion 240 fixed inside the bearing cavity P. After the sensing component 010 is mounted on the bearing surface S0 of the mounting box 200, the sensing component 010 can be located between the abutment portion 240 and the first connecting plate 203. Here, the cooperation between the abutment portion 240 and the first connecting plate 203 can limit the upper and lower sides of the sensing component 010 on the bearing surface S0, ensuring that the sensing component 010 is not easily displaced in the vertical direction.

[0085] In some possible implementations, the mounting box 200 may also include: a first mounting part 205 and a second mounting part 206.

[0086] The first mounting part 205 can be fixedly connected to the first connecting plate 203, and the second mounting part 206 can be fixedly connected to the second connecting plate 204. Both the first mounting part 205 and the second mounting part 206 can be connected to the front panel 110. Here, the mounting box 200 can be mounted on the front panel 110 via the first mounting part 205 and the second mounting part 206.

[0087] In some embodiments, one of the first mounting portion 205 and the second mounting portion 206 of the mounting box 200 is a snap-fit ​​mounting portion, and the other is a fastening mounting portion.

[0088] Among them, such as Figure 11 As shown, Figure 11 yes Figure 3 The diagram shows a partial enlarged view of the mid-frame body at point A. The front panel 110 of the mid-frame body 100 may have a snap-fit ​​groove U corresponding to the snap-fit ​​mounting portion, and a support post Z that mates with the fastening mounting portion. The snap-fit ​​mounting portion of the mounting box 200 can snap into the front panel 110 within the snap-fit ​​groove U, and the fastening mounting portion of the mounting box 200 can be fastened to the support post Z.

[0089] Here, we will take the first mounting part 205 as the fastening mounting part and the second mounting part 206 as the snap-fit ​​mounting part as examples for explanation.

[0090] The second mounting portion 206 may have a snap-fit ​​protrusion that matches the shape of the snap-fit ​​groove U. At least a portion of the snap-fit ​​protrusion of the first mounting portion 205 is located within the snap-fit ​​groove U, thereby enabling it to snap into the front panel 110.

[0091] The first mounting portion 205 may have a through hole V3, and the second mounting portion 206 may rest on the support column Z. The support column Z may have a second threaded hole V4 communicating with the through hole V3 of the second mounting portion 206. Here, when fastening with a screw that matches the second threaded hole V4, the screw can pass through the through hole V3 of the second mounting portion 206 and be threaded into the second threaded hole V4, thereby locking the second mounting portion 206 onto the support column Z.

[0092] Therefore, the mounting box 200 can be fixed to the front panel 110 by engaging the first mounting part 205 at one end of the mounting box 200 with the snap-fit ​​groove U on the front panel 110, and by engaging the second mounting part 206 at the other end of the mounting box 200 with the support column Z on the front panel 110.

[0093] In some embodiments, such as Figure 12 As shown, Figure 12 This is an exploded view of a mid-frame provided in an embodiment of this application. The first mounting box 200a and the second mounting box 200b are adjacently distributed within the mid-frame 000.

[0094] The first support portion 210 in the first mounting box 200a is closer to the second mounting box 200b than the second support portion 220. Since the minimum distance d1 between the first support portion 210 and the front panel 110 in the direction perpendicular to the front panel 110 is less than the minimum distance d2 between the second support portion 220 and the front panel 110, the bearing surface S0 of the first mounting box 200a can be deflected away from the second mounting box 200b relative to the front panel 110, allowing the bearing surface S0 of the first mounting box 200a to face away from the second mounting box 200b. Assuming the first mounting box 200a is located on the left side of the air conditioner, by deflecting the bearing surface S0 of the first mounting box 200a away from the second mounting box 200b relative to the front panel 110, the left-side blind spot of the air conditioner bracket can be eliminated.

[0095] Similarly, the first support portion 210 in the second mounting box 200b is closer to the first mounting box 200a than the second support portion 220. Since the minimum distance d1 between the first support portion 210 and the front panel 110 in the direction perpendicular to the front panel 110 is less than the minimum distance d2 between the first support portion 210 and the front panel 110, it can be ensured that the bearing surface S0 of the second mounting box 200b is deflected away from the first mounting box 200a relative to the front panel 110, allowing the bearing surface S0 of the second mounting box 200b to face away from the first mounting box 200a. Assuming the second mounting box 200b is located on the right side of the air conditioner bracket, by deflecting the bearing surface S0 of the second mounting box 200b away from the first mounting box 200a relative to the front panel 110, the right-side blind spot of the air conditioner bracket can be eliminated.

[0096] Here, by making the first support portion 210 in the first mounting box 200a closer to the second support portion 220 in the second mounting box 200b, and by making the first support portion 210 in the second mounting box 200b closer to the second support portion 220 in the first mounting box 200a, it can be ensured that the bearing surfaces S0 of the two adjacent mounting boxes 200 are distributed opposite to each other. It should be noted that, if it is desired that the bearing surfaces S0 of the two adjacent mounting boxes 200 are distributed facing each other, the second support portion 210 in the first mounting box 200a can be made closer to the second mounting box 200b relative to the first support portion 210, and the second support portion 210 in the second mounting box 200b can be made closer to the first mounting box 200a relative to the first support portion 210.

[0097] In the embodiments of this application, the first mounting box 200a and the second mounting box 200b in the middle frame 000 can be distributed in various ways.

[0098] In one possible implementation, such as Figure 12 As shown, the first mounting box 200a and the second mounting box 200b in the middle frame 000 are centrally symmetrical, and the structure of the first mounting box 200a can be the same as that of the second mounting box 200b. For example, the area where the first mounting box 200a is located can coincide with the area where the second mounting box 200b is located after rotating 180° around the center point of the front panel 110.

[0099] In this case, the first mounting box 200a can be installed on the left side and the second mounting box 200b on the right side, or the first mounting box 200a can be installed on the right side and the second mounting box 200b on the left side. That is, the first mounting box 200a and the second mounting box 200b are no longer limited by their distribution position, and the foolproof design of the first mounting box 200a and the second mounting box 200b can be realized.

[0100] It should be noted that after the first mounting box 200a and the second mounting box 200b, which are centrally symmetrical, are both mounted on the front panel 100, the first mounting part 205 of the first mounting box 200a and the second mounting part 206 of the second mounting box 200b are located on the same side in the second direction Y, and the second mounting part 206 of the first mounting box 200a and the first mounting part 205 of the second mounting box 200b are located on the same side in the second direction Y.

[0101] In another possible implementation, such as Figure 13 As shown, Figure 13 This is an exploded view of another mid-frame provided in an embodiment of this application. The first mounting box 200a and the second mounting box 200b are mirror symmetrical, and the axis of symmetry of the first mounting box 200a and the second mounting box 200b can be parallel to the width direction of the front panel 110 (i.e., the second direction Y). In this case, the structures of the first mounting box 200a and the second mounting box 200b are similar, and they are mirror symmetrical.

[0102] It should be noted that after the mirror-symmetrical first mounting box 200a and second mounting box 200b are both mounted on the front panel 100, the first mounting portion 205 of the first mounting box 200a and the first mounting portion 205 of the second mounting box 200b are located on the same side in the second direction Y, and the second mounting portion 206 of the first mounting box 200a and the second mounting portion 206 of the second mounting box 200b are located on the same side in the second direction Y.

[0103] In summary, because the bearing surface of the mounting box is an inclined surface relative to the front panel, the bearing surfaces of two adjacent mounting boxes are distributed opposite to each other or facing each other. Therefore, by cooperating with the two sensing components in two adjacent mounting boxes, the 180° area in front of the air conditioner can be covered as much as possible, reducing the blind spot range when the air conditioner detects people in front of it through the sensing components, thereby improving the air conditioner's performance.

[0104] This application also provides a housing, which may include a front cover, a middle frame, and a rear shell. The middle frame is the aforementioned middle frame; the front cover can be connected to the front panel of the middle frame; the rear shell can be connected to the side panel of the middle frame opposite to the front panel. Thus, through the cooperation of the front cover and the rear shell, the cavity within the middle frame can be enclosed into a sealed cavity.

[0105] This application also provides an air conditioner, which can be a wall-mounted air conditioner installed indoors, or other types of air conditioners; this application does not limit the specific type. The air conditioner may include the mid-frame as described in the above embodiments, or it may include the outer casing as described in the above embodiments. Furthermore, all functional components of the air conditioner can be installed inside the outer casing.

[0106] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0107] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
