Technical Field

[0001] This utility model relates to the field of air conditioner technology, and more specifically, to a mounting plate assembly for an air conditioner and an air conditioner. Background Technology

[0002] Currently, the installation process of air conditioner mounting plates presents numerous inconveniences. Traditional installation methods typically require the use of multiple screws for fixing. During the tightening process, the rotational torque of the screws can cause displacement of the mounting lugs, resulting in the actual installation position of the lugs deviating from the preset ideal position. Furthermore, the use of multiple fasteners not only increases the complexity of the installation and prolongs the installation time, but also easily leads to a decrease in installation accuracy due to the interaction forces between the fasteners. Utility Model Content

[0003] The problem solved by this invention is: how to fix the hook with fewer fasteners and prevent the hook from shifting during the fixing process.

[0004] To address the aforementioned problems, this utility model provides a mounting plate assembly for an air conditioner. The mounting plate assembly includes: a mounting ear; and a insert plate, which is connected to the mounting ear. A first gap exists between the mounting ear and the insert plate. At least a portion of the insert plate enters the mounting groove of the air conditioner's outer casing to fix the mounting ear. When the mounting ear is fixed to the outer casing, the side of the mounting groove away from the outer casing is located within the first gap.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: the matching design of the mounting slot and the insert plate reduces the number of fasteners while ensuring installation strength, effectively suppresses the possible displacement of the hanging ears during the fastening process, eliminates assembly errors caused by differences in the operation sequence of multiple fasteners, reduces the workload of workers installing the mounting plate components, and improves installation efficiency.

[0006] In one embodiment of this utility model, the hanging ear and the insert plate are integrally formed.

[0007] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the integrated molding of the hanging ear and the insert plate avoids the cumbersome assembly steps caused by fixing the hanging ear and the insert plate in stages, reduces the number of connecting parts, eliminates the risk of relative displacement of the split structure under stress, and improves positioning accuracy.

[0008] In one embodiment of the present invention, the insert plate includes: an extension section, which is fixedly connected to the hanging ear; and a snap-fit ​​section, which is engaged with the extension section, at least a portion of which can enter the mounting groove; wherein, when the snap-fit ​​section is located in the mounting groove, the extension section is located between the hanging ear and the outer shell.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the extension section makes the fit between the snap-fit ​​section and the mounting slot more convenient. At the same time, after the snap-fit ​​section enters the mounting slot, the extension section, together with the lug and the snap-fit ​​section, can snap the outer side of the mounting slot, making the lug more secure.

[0010] In one embodiment of this utility model, a first connecting hole is provided on the snap-fit ​​section, and a second connecting hole is provided on the mounting groove. The centers of the first connecting hole and the second connecting hole are located on the same axis, and a single fastener passes through the second connecting hole and the first connecting hole in sequence to fix the hanging ear.

[0011] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting the first connection hole and the second connection hole, the fastener can pass through the insert plate and the mounting groove. After the fastener is tightened, the connection strength of the individual fastener can be improved by utilizing the thickness of the outer wall of the insert plate and the mounting groove.

[0012] In one embodiment of this utility model, the ear is provided with a connection opening. When the ear is fixed to the outer shell, the connection opening is located on the side of the ear closer to the outer shell; wherein, the connection opening can completely cover the first connection hole and the second connection hole.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the setting of the connection opening makes it easy for workers to observe the first and second connection holes and quickly determine whether the insert plate is in the installation position. The setting of the connection opening can completely cover the first and second connection holes, allowing workers to control the fasteners to pass through the connection opening into the second and first connection holes, thus increasing the work efficiency of fixing the hanging ears.

[0014] In one embodiment of this utility model, the hanging plate assembly further includes: a limiting block, which is fixedly connected to the outer shell and abuts against the edge of the hanging ear; wherein, when the fastener is fixing the insert plate, the hanging ear can contact the limiting block.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: the setting of the limiting block abutting against the edge of the hanging ear allows a single fastener to not only fix the hanging ear, but also effectively prevent the hanging ear from shifting due to rotational torque during installation, ensuring that the hanging ear and the shell are precisely aligned, simplifying the installation steps while improving the reliability of positioning.

[0016] In one embodiment of this utility model, the hook includes: a first connecting plate having a connecting opening; a second connecting plate being fixedly connected to the first connecting plate; a reinforcing rib being disposed on the side of the first connecting plate away from the insert plate and protruding in a direction away from the insert plate; and / or; the reinforcing rib being disposed on the side of the second connecting plate away from the insert plate and protruding in a direction away from the insert plate; wherein, the extension section is located on the side of the connecting opening away from the second connecting plate.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the setting of reinforcing ribs makes the overall structural strength of the hanging ear more consistent with the connection method of fixing with individual fasteners, preventing the fixing position deviation caused by deformation or displacement of the hanging ear during installation, and improving the stability of the hanging ear connection.

[0018] In one embodiment of this utility model, there are multiple reinforcing ribs, which are arranged side by side and spaced apart at the connection points with the first connecting plate and the second connecting plate.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the setting of multiple reinforcing ribs allows the stress applied to the lug by a single fastener during tightening to be distributed, and the parallel and spaced arrangement also makes the lug more aesthetically pleasing.

[0020] In one embodiment of this utility model, the hanging ear further includes a wiring groove, which is located on the side of the second connecting plate away from the first connecting plate, and the wiring groove is hollowed out.

[0021] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting up cable trays, the cable layout of the air conditioner becomes more convenient after the mounting plate assembly is installed, the cable fixing process is simplified, and the installation efficiency of subsequent air conditioner installation is improved after the mounting ears are installed.

[0022] In one embodiment of this utility model, an air conditioner is also provided, including: a mounting plate surface, on which a mounting groove is provided, and the mounting plate assembly described above is connected to the mounting groove.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 and Figure 2 In one specific embodiment, this application provides a mounting plate assembly 200 for an air conditioner. The mounting plate assembly 200 includes: a mounting ear 220; and a plug plate 300. The plug plate 300 is connected to the mounting ear 220, and a first gap 330 is formed between the mounting ear 220 and the plug plate 300. At least a portion of the plug plate 300 enters the mounting groove 120 of the air conditioner housing 110 to fix the mounting ear 220. When the mounting ear 220 is fixed to the housing 110, the side of the mounting groove 120 away from the housing 110 is located within the first gap 330.

[0027] The mounting plate assembly 200 is fixedly connected to the air conditioner housing 110 via the insert plate 300 provided on the mounting ear 220. Typically, the air conditioner housing 110 has a mounting groove 120 that matches the insert plate 300. The insert plate 300 is fixed to the air conditioner by entering the mounting groove 120. The mounting groove 120 is usually U-shaped, and the insert plate 300 is rectangular. After inserting the insert plate 300 into the mounting groove 120, the mounting ear 220 can be fixed to the air conditioner housing 110.

[0028] When the mounting ear 220 is in the installation position, the insert plate 300 extends towards the outer casing 110 of the air conditioner, and the extended part and the mounting ear 220 form a mounting groove 120. When the insert plate 300 is inserted into the mounting groove 120, the first gap 330 accommodates the outer edge of the mounting groove 120, forming a vertical stop structure, so that the mounting groove 120 and the insert plate 300 can be engaged with each other. There are various ways to connect the insert plate 300 and the mounting groove 120, including but not limited to welding, snap-fit, magnetic attraction and screw connection.

[0029] The matching arrangement of the mounting slot 120 and the insert plate 300 reduces the number of fasteners 340 while ensuring installation strength. It also effectively suppresses the possible displacement of the hanging ear 220 during the fastening process, eliminates assembly errors caused by differences in the operation sequence of multiple fasteners 340, reduces the workload of workers installing the mounting plate assembly 200, and improves installation efficiency.

[0030] Furthermore, the ear loop 220 and the insert plate 300 are integrally molded.

[0031] One-piece molding refers to the continuous processing of materials to form a single integral structure between the lug 220 and the insert plate 300. This can be achieved by injection molding, stamping, or casting. The one-piece molding design eliminates the assembly gap between the two parts, eliminating the risk of displacement caused by assembly errors in the separate connection, and avoiding the deviation of the fixed position caused by loose connection during installation.

[0032] Normally, since there is no relative movement inside the integrated structure, when the insert plate 300 enters the mounting slot 120 of the air conditioner housing 110, the position of the hanging ear 220 is directly determined by the insertion depth of the insert plate 300. During the installation process, the staff only needs to control the cooperation between the insert plate 300 and the mounting slot 120 to complete the positioning, which simplifies the assembly process. The integrated design of the lug 220 and the insert plate 300 avoids the cumbersome assembly steps caused by fixing the lug 220 and the insert plate 300 in stages, reduces the number of connecting parts, eliminates the risk of relative displacement under stress in a split structure, and improves positioning accuracy.

[0033] Furthermore, the insert plate 300 includes: an extension section 310, which is fixedly connected to the lug 220; and a snap-fit ​​section 320, which is engaged with the extension section 310, at least a portion of which can enter the mounting groove 120; wherein, when the snap-fit ​​section 320 is located in the mounting groove 120, the extension section 310 is located between the lug 220 and the housing 110.

[0034] The extension section 310 refers to a plate-like structure extending from the main body of the insert plate 300 towards the outer casing 110. The extension section 310 creates a first gap 330 between the snap-fit ​​section 320 and the lug 220, facilitating the overall mating of the insert plate 300 with the mounting groove 120. The shape of the snap-fit ​​section 320 is typically adapted to the shape of the mounting groove 120. Generally, it is necessary to ensure that the snap-fit ​​section 320 can enter the mounting groove 120 and is compatible with its shape and size, increasing the stability of the connection between the snap-fit ​​section 320 and the mounting groove 120. After the snap-fit ​​section 320 enters the mounting groove 120, the physical limiting effect of the groove wall constrains the displacement of the insert plate 300. Typically, the extension section 310 and the snap-fit ​​section 320 form a 90° angle. During the assembly of the mounting plate assembly 200, the contact surface between the snap-fit ​​section 320 and the wall of the mounting groove 120 forms multi-point limiting, replacing the traditional multi-screw fixing method, thereby reducing the number of fasteners 340. When the snap-fit ​​section 320 is fully embedded in the mounting groove 120, the extension section 310, the lug 220 and the snap-fit ​​section 320 clamp the outer wall of the mounting groove 120 in the first gap 330, further restricting the relative movement of the insert plate 300 and the lug 220 through frictional resistance, achieving a double limiting effect.

[0035] The extension section 310 makes the engagement between the snap-fit ​​section 320 and the mounting slot 120 more convenient. At the same time, after the snap-fit ​​section 320 enters the mounting slot 120, the extension section 310, together with the hanging ear 220 and the snap-fit ​​section 320, can snap the outer side of the mounting slot 120, making the fixing of the hanging ear 220 more stable.

[0036] See Figure 3 and Figure 4 Furthermore, the snap-fit ​​section 320 is provided with a first connecting hole 321, and the mounting groove 120 is provided with a second connecting hole 130. The centers of the first connecting hole 321 and the second connecting hole 130 are located on the same axis. A single fastener 340 passes through the second connecting hole 130 and the first connecting hole 321 in sequence to fix the lug 220.

[0037] The first connecting hole 321 is a through hole provided on the snap-fit ​​section 320 of the insert plate 300. The diameter of the first connecting hole 321 matches the outer diameter of the fastener 340 to achieve a clearance fit. The second connecting hole 130 is a positioning hole provided on the outer side of the mounting groove 120. The position of the second connecting hole 130 corresponds axially to that of the first connecting hole 321. When the snap-fit ​​section 320 of the insert plate 300 is inserted into the mounting slot 120 and moved to the correct position, the first connecting hole 321 aligns with the second connecting hole 130. Normally, the correct position is when the snap-fit ​​section 320 enters the bottom of the mounting slot 120 and cannot move further into the slot. The operator then passes a single fastener 340 sequentially through the second connecting hole 130 and the first connecting hole 321 to complete the fixing of the mounting lug 220 to the air conditioner housing 110. The fastener 340 is typically a screw.

[0038] It should be noted that after the fastener 340 has secured the hanging ear 220, the individual fastener 340 can also achieve a good fixing effect with the support of the thickness of the insert plate 300 and the outer wall thickness of the mounting groove 120, preventing the hanging ear 220 from shaking during the installation of the air conditioner.

[0039] By setting the first connecting hole 321 and the second connecting hole 130, the fastener 340 can pass through the insert plate 300 and the mounting groove 120. After the fastener 340 is tightened, the connection strength of the individual fastener 340 can be improved by utilizing the thickness of the outer wall of the insert plate 300 and the mounting groove 120.

[0040] Furthermore, the ear loop 220 is provided with a connection opening 230. When the ear loop 220 is fixed to the outer shell 110, the connection opening 230 is located on the side of the ear loop 220 close to the outer shell 110. The connection opening 230 can completely cover the first connection hole 321 and the second connection hole 130.

[0041] The connecting opening 230 refers to the through structure on the surface of the lug 220, typically a rectangular through hole. The coverage area of ​​the connecting opening 230 is larger than the combined projection range of the first connecting hole 321 and the second connecting hole 130, ensuring that the positions of the first connecting hole 321 and the second connecting hole 130 can be exposed through the connecting opening 230. This allows workers to directly observe the hole alignment from the outside of the lug 220 during installation and proceed directly with the installation without needing to fasten the fastener 340 from the first gap 330. Generally, the coverage area of ​​the connecting opening 230 is more than five times larger than the coverage area of ​​the first connecting hole 321 and the second connecting hole 130 to facilitate installation. When the lug 220 is fixed to the housing 110 by the fastener 340, the position of the connection opening 230 corresponds to the mounting groove 120 on the housing 110. The operator can observe the positions of the first connection hole 321 and the second connection hole 130 through the connection opening 230 to quickly determine whether the lug 220 is in the preset installation position. If so, the fastener 340 is used to fix the insert plate 300 to the outer wall of the mounting groove 120. If not, the position of the insert plate 300 within the mounting groove 120 is adjusted to move the lug 220 to the preset installation position. Then, the fastener 340 is passed through the connection opening 230 and sequentially inserted into the second connection hole 130 and the first connection hole 321 to complete the fixing.

[0042] Compared to the traditional method of installing the ear loop 220, which requires multiple fasteners 340 to be combined and fixed, the method of fixing with a single fastener 340 is not only more convenient, but also reduces the impact of positional displacement caused by each fastener 340 during fixing.

[0043] The connection opening 230 allows workers to easily observe the first connection hole 321 and the second connection hole 130, quickly determining whether the insert plate 300 is in the installation position. The connection opening 230 can completely cover the first connection hole 321 and the second connection hole 130, allowing workers to control the fastener 340 to pass through the connection opening 230 into the second connection hole 130 and the first connection hole 321, increasing the efficiency of fixing the hanging ear 220.

[0044] See Figure 5 and Figure 6 Furthermore, the mounting plate assembly 200 also includes a limiting block 400, which is fixedly connected to the housing 110 and abuts against the edge of the hanging ear 220; wherein, when the fastener 340 fixes the insert plate 300, the hanging ear 220 can contact the limiting block 400.

[0045] The limiting block 400 is a blocking component that is rigidly connected to the air conditioner housing 110. It is usually a metal block that is welded or bolted. The limiting block 400 is usually half a cylinder in shape, and its cross section faces the hanging ear 220. The installation position of the limiting block 400 forms a contact surface with the edge of the hanging ear 220, and generates a reaction force when the fastener 340 applies torque. During installation, after the snap-fit ​​section 320 enters the mounting groove 120 and moves to the preset installation position, the limiting block 400 makes physical contact with the edge of the lug 220 beforehand. When the fastener 340 is tightened through the second connecting hole 130 and the first connecting hole 321, the lug 220 is subjected to the circumferential force generated by the rotation of the screw. At this time, the limiting block 400 forms a rigid block on the edge of the lug 220, counteracting the rotational torque. Due to the coaxial design of the second connecting hole 130 and the first connecting hole 321, the relative positions of the insert plate 300 and the lug 220 in the mounting groove 120 are forcibly aligned, preventing the lug 220 from undergoing lateral displacement. Before the fastener 340 is fully tightened, the contact surface between the limiting block 400 and the lug 220 has established stable support, thereby eliminating the risk of deflection caused by the fixing of a single fastener 340 during installation.

[0046] The setting of the limiting block 400 abutting against the edge of the hanging ear 220 allows the single fastener 340 to not only fix the hanging ear 220, but also effectively prevent the hanging ear 220 from shifting due to rotational torque during installation. This ensures that the hanging ear 220 and the installation position of the outer shell 110 are accurately aligned, simplifying the installation steps while improving the reliability of positioning.

[0047] Furthermore, the lug 220 includes: a first connecting plate 221, the first connecting plate 221 having a connecting opening 230; a second connecting plate 222, the first connecting plate 221 and the second connecting plate 222 being fixedly connected; a reinforcing rib 240, the reinforcing rib 240 being located on the side of the first connecting plate 221 away from the insert plate 300 and protruding in a direction away from the insert plate 300; and / or; the reinforcing rib 240 being located on the side of the second connecting plate 222 away from the insert plate 300 and protruding in a direction away from the insert plate 300; wherein, the extension section 310 is located on the side of the connecting opening 230 away from the second connecting plate 222.

[0048] The first connecting plate 221 is a plate-shaped structure with a connecting opening 230. When the mounting ear 220 is in the preset installation position, the first connecting plate 221 is parallel to the outer casing 110 of the air conditioner. The second connecting plate 222 is fixedly connected to the first connecting plate 221, or it can be integrally formed. Typically, the included angle between the second connecting plate 222 and the first connecting plate 221 is 90°. The reinforcing rib 240 refers to the protruding structure provided on the outer side of the plate. Multiple reinforcing ribs 240 are distributed on the first connecting plate 221 and the second connecting plate 222, increasing the overall strength of the mounting ear 220.

[0049] The reinforcing rib 240 is provided on the outer surface of the first connecting plate 221 or the second connecting plate 222. During the locking process of the fastener 340, the structural strength provided by the reinforcing rib 240 to the hanging ear 220 can prevent the hanging ear 220 from deforming as a whole, so as to adapt to the impact of fixing a single fastener 340.

[0050] The addition of reinforcing rib 240 makes the overall structural strength of the hook 220 more compatible with the connection method of fixing with a single fastener 340, preventing the hook 220 from deviating in its fixed position due to deformation or displacement under force during installation, and improving the stability of the hook 220 connection.

[0051] Furthermore, there are multiple reinforcing ribs 240, which are arranged side by side and spaced apart at the connection points with the first connecting plate 221 and the second connecting plate 222.

[0052] Multiple reinforcing ribs 240 are used to enhance the bending resistance of the joint. The parallel and spaced arrangement means that multiple reinforcing ribs 240 are arranged parallel to each other along the length of the joint, with gaps between them. This can be achieved through equidistant or non-uniform distribution, ensuring structural strength while avoiding material redundancy. Multiple parallel reinforcing ribs 240 form multiple support lines during the installation of the lugs 220. When the fasteners 340 apply rotational force, the load is distributed throughout the connection area through the reinforcing ribs 240, preventing local stress concentration from causing the connection plate to twist. The spacing creates a buffer zone between the reinforcing ribs 240, allowing the connection plate to undergo slight elastic deformation under stress, thus avoiding brittle fracture due to excessive rigidity. The multiple reinforcing ribs 240 allow the stress applied to the lug 220 by a single fastener 340 during tightening to be distributed, and the parallel and spaced arrangement also makes the lug 220 more aesthetically pleasing.

[0053] Furthermore, the hanging ear 220 also includes a wiring groove 250, which is located on the side of the second connecting plate 222 away from the first connecting plate 221, and the wiring groove 250 is hollowed out.

[0054] The cable tray 250 is a groove structure that accommodates cables. The hollow setting means that the bottom and side walls of the cable tray 250 form an open space, which is achieved by removing the material of the corresponding area of ​​the second connecting plate 222. After the hanging ear 220 is fixed, the air conditioning related circuits are adjusted through the cable tray 250.

[0055] By setting up the cable tray 250, the cable layout of the air conditioner becomes more convenient after the mounting plate assembly 200 is installed, simplifying the cable fixing process and improving the installation efficiency of the air conditioner after the mounting ears 220 are installed.

[0056] This application also provides an air conditioner including a mounting plate surface, on which a mounting groove 120 is provided. The mounting plate assembly 200 described above is connected to the mounting groove 120. The mounting plate assembly 200 has all the technical features of the mounting plate assembly 200 described above, which will not be repeated here.

[0057] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
