DETAILED DESCRIPTION

[0029] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Reference should be made to Figures 1 to 7The application provides an electric appliance box assembly, comprising: a box body 100, a control panel 110 arranged in the box body 100; a first support 200 arranged on a first side of the box body 100 and connected with the box body 100, a first wire passing part 210 arranged on the first support 200, the first wire passing part 210 being used for accommodating a first cable bundle; a second support 300 arranged on a second side of the box body 100 and connected with the box body 100, a second wire passing part 310 arranged on the second support 300, the second wire passing part 310 being used for accommodating a second cable bundle; and a third wire passing part 400 arranged on the box body 100 and located between the first support 200 and the second support 300, the first cable bundle and the second cable bundle being connected with the control panel 110 by passing through the third wire passing part 400.

[0031] According to the electric appliance box assembly provided by the application, the box body 100, the first support 200, the second support 300 and the third wire passing part 400 are arranged, the control panel 110 is arranged in the box body 100, the first support 200 is arranged on the first side of the box body 100 and connected with the box body 100, the first wire passing part 210 is arranged on the first support 200, the first wire passing part 210 is used for accommodating the first cable bundle, the second support 300 is arranged on the second side of the box body 100 and connected with the box body 100, the second wire passing part 310 is arranged on the second support 300, the second wire passing part 310 is used for accommodating the second cable bundle, and the third wire passing part 400 is arranged on the box body 100 and located between the first support 200 and the second support 300, the first cable bundle and the second cable bundle are connected with the control panel 110 by passing through the third wire passing part 400. By arranging the supports and the wire passing parts on the two sides of the box body, the internal space of the electric appliance box assembly is reasonably utilized, the cables are prevented from occupying too much space, more mounting positions are provided for other important components, the internal layout of the electric appliance box is optimized, and the compactness of the overall structure is facilitated. By arranging the first cable bundle (strong electric cable) and the second cable bundle (weak electric cable) on the first side and the second side of the box body respectively and guiding the first cable bundle and the second cable bundle through the first wire passing part and the second wire passing part, the direct contact and overlapping of the strong electric cable and the weak electric cable in the traditional design are avoided, the electromagnetic interference is significantly reduced, and the electrical safety of the electric appliance box and the entire air conditioning system is improved.

[0032] The arrangement of the first support and the second support not only realizes classified management of the cables, but also simplifies the wiring path of the cables and shortens the cable length, which not only reduces the wire cost, but also reduces the assembly cost and maintenance cost caused by cable disorder. The first support and the second support are respectively connected with the box body and an external structure (such as a moving part support and a chassis), forming a stable triangular support structure, enhancing the structural strength of the electric appliance box assembly, effectively preventing the forward tilting problem of the air conditioner caused by unstable center of gravity during use, and improving the stability of the whole machine. The arrangement of the third wire passing part enables the first cable bundle and the second cable bundle to be introduced from the first side and the second side of the box body respectively, and then connected with the control panel through the third wire passing part. This design greatly simplifies the assembly process of the electric appliance box assembly, and also facilitates the later maintenance and maintenance, without the need to disassemble the whole electric appliance box to replace or repair the cables.

[0033] Specifically, as shown in Figures 2 to 5 The electric appliance box assembly further comprises: a first limiting part 500 arranged opposite to the first wire passing part 210, and a first limiting space is arranged between the first limiting part 500 and the first wire passing part 210; and a second limiting part 600 arranged opposite to the second wire passing part 310, and a second limiting space is arranged between the second limiting part 600 and the second wire passing part 310. Through the arrangement of the first limiting part 500 and the second limiting part 600, the wire arrangement can be effectively fixed, and the displacement and misplacement of the cable bundle in the electric appliance box can be avoided. The limiting space between the limiting part and the wire passing part can effectively prevent the short circuit of the line, especially between the strong current and weak current lines, reduce the fire hazard, and improve the overall safety performance of the electric appliance box assembly.

[0034] The fixing effect of the limiting part makes it easier to position and install the cable bundle during assembly, reduces the assembly time, improves the production efficiency, and is beneficial to large-scale production.

[0035] In the specific implementation process, the first wire passing part 210 comprises a first wire passing groove 211, the first limiting part 500 is arranged opposite to the groove bottom surface of the first wire passing groove 211, and the first limiting space is located between the first wire passing groove 211 and the first limiting part 500; and / or the second wire passing part 310 comprises a second wire passing groove 311, the second limiting part 600 is arranged opposite to the groove bottom surface of the second wire passing groove 311, and the second limiting space is located between the second wire passing groove 311 and the second limiting part 600. The first wire passing groove 211 and the second wire passing groove 311 guide the strong current line and the weak current line to independent limiting spaces respectively, avoiding the intersection of the strong current line and the weak current line in space, significantly reducing the electromagnetic interference, and ensuring the stability and reliability of the equipment. The design of the wire passing groove and the limiting part optimizes the wire arrangement path, makes the line management more standardized, reduces the complexity of the wire arrangement, and makes the assembly and maintenance more convenient and efficient.

[0036] The first bracket 200 is provided with a first avoiding recess 220, the first avoiding recess 220 is communicated with the first wire passing part 210, the first limiting part 500 comprises: a first limiting plate 510, at least part of the first limiting plate 510 is arranged in the first avoiding recess 220. The first bracket 200 is equipped with the first avoiding recess 220, the first avoiding recess 220 is communicated with the first wire passing part 210, the design purpose is to better manage and protect the wire harness passing through the bracket. The first limiting plate 510 in the first limiting part 500 is at least partially arranged in the first avoiding recess 220, so that the design can effectively limit the movement of the wire harness in the bracket, prevent the wire harness from loosening or damaging due to vibration or external force, and also help to keep the wire harness neat, improve the beauty of the equipment interior and reduce the maintenance difficulty.

[0037] In the assembly process, the first avoiding recess 220 can also limit the first limiting plate 510, and the design of the first avoiding recess 220 makes the first limiting plate 510 closer to the first wire passing groove 211, so that the first limiting plate 510 enhances the limiting effect on the strong current wire harness 910 in the first wire passing groove 211.

[0038] The second bracket 300 is provided with a second avoiding recess 320, the second avoiding recess 320 is communicated with the second wire passing part 310, the second limiting part 600 comprises: a second limiting plate 610, at least part of the second limiting plate 610 is arranged in the second avoiding recess 320. Similarly, the second bracket 300 is equipped with the second avoiding recess 320, the second avoiding recess 320 is communicated with the first wire passing part 210, the design purpose is to better manage and protect the wire harness passing through the bracket. The second limiting plate 610 in the second limiting part 600 is at least partially arranged in the second avoiding recess 320, so that the design can effectively limit the movement of the wire harness in the bracket, prevent the wire harness from loosening or damaging due to vibration or external force, and also help to keep the wire harness neat, improve the beauty of the equipment interior and reduce the maintenance difficulty.

[0039] In the assembly process, the second avoiding recess 320 can also limit the second limiting plate 610, and the design of the second avoiding recess 320 makes the second limiting plate 610 closer to the second wire passing groove 311, so that the second limiting plate 610 enhances the limiting effect on the weak current wire harness 920 in the second wire passing groove 311.

[0040] In the implementation process, the first limiting component 500 is arranged on the first side of the control panel 110, the first limiting component 500 includes a first connecting end and a first free end arranged oppositely, the first connecting end is connected with the control panel 110, and the first free end extends towards the direction close to the first support 200; the second limiting component 600 is arranged on the second side of the control panel 110, the second limiting component 600 includes a second connecting end and a second free end arranged oppositely, the second connecting end is connected with the control panel 110, and the second free end extends towards the direction close to the second support 300; the first limiting component 500 and the second limiting component 600 are in an integrated molding structure with the control panel 110. The limiting component and the control panel are in an integrated molding structure, which avoids the assembly of additional components, simplifies the assembly process of the electrical box assembly, reduces the assembly time, reduces the failure rate caused by improper assembly, and improves the overall assembly efficiency and production quality. The design of the limiting component is directly implemented on the control panel, without the need for additional space to install independent limiting components, which makes the internal layout of the electrical box more compact, saves valuable space resources, and is conducive to the miniaturization and modularization design of the electrical box assembly.

[0041] Further, the box body 100 is provided with a third avoiding notch 120, at least part of the first limiting component 500 is located in the third avoiding notch 120; the box body 100 is also provided with a through channel 130, at least part of the second limiting component 600 passes through the through channel 130 and is opposite to the second wire passing part 310. The introduction of the avoiding notch and the through channel provides a more accurate guide path for the cable, so that the first cable bundle and the second cable bundle can be fixed and passed through more orderly, avoiding the disorderly winding of the cable in the electrical box, improving the neatness and management efficiency of the cable layout. The design of the third avoiding notch 120 and the through channel 130 reasonably utilizes the internal space of the box body 100, not only provides installation positions for the first and second limiting components, but also ensures that the cable can be connected with the control panel in the shortest path, reduces space waste, and is conducive to the miniaturization and compactness of the electrical box assembly.

[0042] The combination of the limiting component and the avoiding notch and the through channel not only can fix the cable, but also can enhance the mechanical strength of the electrical box assembly. The installation of the limiting component in the specific notch and channel ensures the stability of the cable when the electrical box assembly is subjected to external impact, reducing the risk of connection loosening or damage caused by the movement of the cable.

[0043] In the assembling process, the second limiting plate 610 is firstly used to pre-position the control plate 110 by penetrating through the passage 130, at this time, the second limiting plate 610 extends into the second avoiding recess 320 to form a stop action on the second wire harness in the second wire passing groove 311, then the control plate 110 is completely put into the box body 100, at this time, the first limiting plate 510 extends into the third avoiding recess 120 and the first avoiding recess 220, so that the first limiting plate 510 forms a stop action on the first wire harness in the first wire passing groove 211, and at the same time, the control plate 110 is also installed at a predetermined position in the box body 100 under the limiting action of the third avoiding recess 120, therefore, the first limiting plate 510 and the second limiting plate 610 not only play a stop action on the first wire harness and the second wire harness, but also play a positioning action on the control plate 110 when the control plate 110 is installed.

[0044] Specifically, the control plate 110 comprises a fixed back plate 111 and a main plate 112, the main plate 112 is installed on the fixed back plate 111, and the first limiting plate 510 and the second limiting plate 610 are integrally formed with the fixed back plate 111.

[0045] In the embodiments provided in the application, the first support 200 comprises a first support body 230 and a second support body 240 which are oppositely arranged, the first support body 230 and the second support body 240 are connected through a third support body 250, the first wire passing part 210 is arranged between the first support body 230, the second support body 240 and the third support body 250, and the first support body 230 is connected with the box body 100; the second support body 240 is provided with the first avoiding recess 220, at least part of the first limiting part 500 is located in the first avoiding recess 220 and opposite to the third support body 250. In order to avoid the interference of the first support body 230 on the first limiting part 500, the height of the first support body 230 is less than that of the second support body 240, so that the first wire harness can also be limited by the first side surface of the box body 100.

[0046] The first wire passing part 210 is arranged between the first frame 230, the second frame 240 and the third frame 250 to form a polygonal cable channel, which makes the cable arrangement more standardized, avoids cable confusion and crossing, improves the neatness of the electrical box interior, and facilitates maintenance and inspection. The cooperation of the first avoiding notch 220 on the second frame 240 and the first limiting part 500 can more firmly fix the cable, prevent the cable from loosening or damaging due to vibration during equipment operation or transportation, and improve the safety of the cable. The combined design of the first frame 230, the second frame 240 and the third frame 250 forms a more stable support structure, enhances the carrying capacity and impact resistance of the electrical box assembly, especially when part of the first limiting part 500 is placed in the first avoiding notch 220 and opposite to the third frame 250, this structure can better fix the electrical box assembly to avoid tilting or shaking.

[0047] The second support 300 comprises: oppositely arranged fourth frame 330 and fifth frame 340, the fourth frame 330 and the fifth frame 340 are connected by the sixth frame 350, the second wire passing part 310 is arranged between the fourth frame 330, the fifth frame 340 and the sixth frame 350, the fourth frame 330 is connected with the box body 100; The second avoiding notch 320 is arranged on the fifth frame 340, at least part of the second limiting part 600 is located in the second avoiding notch 320, and opposite to the sixth frame 350. In order to avoid the interference of the fourth frame 330 to the second limiting part 600, the height of the fourth frame 330 is less than that of the fifth frame 340, so that the second wire harness can be limited by the second side of the box body 100.

[0048] The second wire passing part 310 is located in the area formed by the fourth frame, the fifth frame and the sixth frame, which not only provides a physical barrier for the cable to prevent it from being damaged by external mechanical damage, but also ensures that the cable is fixed when passing through the second wire passing part by setting part of the second limiting part 600 in the second avoiding notch 320, avoiding cable wear or loosening caused by vibration or movement. By arranging the second wire passing part 310 between the internal structures of the second support 300, the space of the second support is fully utilized, the space in the electrical box assembly is effectively saved, more installation space is provided for other key components, which is conducive to optimizing the overall layout and making the electrical box assembly more compact.

[0049] Since the strong current cable and the weak current cable are guided through different wire passing parts of the first support and the second support respectively, this separated wiring method can further reduce electromagnetic interference, ensure the clarity and stability of signal transmission, and improve the electromagnetic compatibility of the electrical box assembly.

[0050] The application also provides an air conditioner, comprising a machine body 700 and an electrical box assembly 800, the electrical box assembly 800 is arranged in the machine body 700, and the electrical box assembly 800 is the electrical box assembly in the above-mentioned embodiment.

[0051] The electrical box assembly 800 significantly reduces electromagnetic interference by respectively routing strong current wires and weak current wires, isolating the wires by using the first wire passing part and the second wire passing part, and further fixing and managing the cables by using the limiting part, ensures the precise operation of the air conditioner control system, and improves the electromagnetic compatibility of the whole machine. The design of the electrical box assembly 800 effectively avoids the risk of line contact short circuit and fire, reduces the safety hidden danger caused by line fault through separate wiring and fixed limiting, and protects the life and property safety of the user. The electrical box assembly 800 optimizes the cable management and layout, simplifies the assembly process, is convenient for maintenance and inspection, reduces the cost and time consumption of the air conditioner in the production and maintenance process, and improves the work efficiency.

[0052] The air conditioner further comprises: a bottom plate 710 arranged at the bottom of the body 700; a driving assembly 720, the driving assembly 720 comprising a driving component 721 and a mounting bracket 722, the driving component 721 being arranged on the mounting bracket 722 and being movably arranged relative to the mounting bracket 722, the driving component 721 being drivingly connected with an air duct panel 730 of the air conditioner to drive the air duct panel 730 to move; two ends of a first bracket 200 of the electrical box assembly 800 being respectively connected with the mounting bracket 722 and the bottom plate 710; and / or two ends of a second bracket 300 of the electrical box assembly 800 being respectively connected with the mounting bracket 722 and the bottom plate 710. The two ends of the first bracket 200 and the second bracket 300 are respectively connected with the mounting bracket 722 and the bottom plate 710, forming a stable triangular support structure. This structure can effectively disperse and bear the force generated by the driving assembly 720 when operating the air duct panel 730, avoiding deformation or damage of the electrical box assembly 800 or the air duct panel 730 caused by uneven local stress, and improving the overall structural stability and service life of the air conditioner. Since the brackets of the electrical box assembly 800 are directly connected with the mounting bracket 722 of the driving assembly 720, this helps to further isolate the strong and weak electric wires inside the electrical box. The cables connected with other components of the air conditioner are orderly managed through the first wire passing part 210 and the second wire passing part 310, reducing electromagnetic interference between the cables and ensuring that the electrical system of the air conditioner can still operate stably in a complex environment. The design of the brackets not only strengthens the stability of the structure, but also provides space for cable management and limiting. During maintenance and repair, the driving assembly 720 and the electrical box assembly 800 can be easily accessed without the need to disassemble the entire air conditioner, reducing maintenance cost and time. By connecting the first bracket 200 and the second bracket 300 with the mounting bracket 722 and the bottom plate 710, the internal space of the air conditioner is more reasonably utilized. This design avoids the interference that may occur when the electrical box assembly 800 is directly connected with the air duct panel 730, providing more installation space for other key components and optimizing the layout and design of the air conditioner.

[0053] The application provides a novel wiring method, in which the strong electric motor hot wire is arranged in the left support strip groove (first wire passing part 210) of the electrical box component, and the weak point line stepper motor wire and the fan wire are arranged in the right support strip groove (second wire passing part 310) of the electrical box component, thereby reducing the electromagnetic interference ability of strong and weak electricity, solving the problem that a large number of strong and weak wire bundles are crossed and contacted together, and easily causing a fire, and being beneficial to normal work of the air conditioner.
