DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Please refer to Figures 1 to 7The present application provides an electrical box assembly, including: a box body 100, in which a control board 110 is arranged; a first bracket 200, which is arranged on a first side of the box body 100 and connected to the box body 100, and a first wire-passing portion 210 is arranged on the first bracket 200, and the first wire-passing portion 210 is used to accommodate a first cable bundle; a second bracket 300, which is arranged on a second side of the box body 100 and connected to the box body 100, and a second wire-passing portion 310 is arranged on the second bracket 300, and the second wire-passing portion 310 is used to accommodate a second cable bundle; a third wire-passing portion 400, which is arranged on the box body 100 and located between the first bracket 200 and the second bracket 300, and the first cable bundle and the second cable bundle are respectively connected to the control board 110 through the third wire-passing portion 400.

[0031] According to the electrical box assembly provided in the present application, it includes a box body 100, a first bracket 200, a second bracket 300 and a third wire-passing portion 400, and a control board 110 is arranged in the box body 100; the first bracket 200 is arranged on a first side of the box body 100 and is connected to the box body 100, and a first wire-passing portion 210 is arranged on the first bracket 200, and the first wire-passing portion 210 is used to accommodate a first cable bundle; the second bracket 300 is arranged on a second side of the box body 100 and is connected to the box body 100, and a second wire-passing portion 310 is arranged on the second bracket 300, and the second wire-passing portion 310 is used to accommodate a second cable bundle; the third wire-passing portion 400 is arranged on the box body 100 and is located between the first bracket 200 and the second bracket 300, and the first cable bundle and the second cable bundle are respectively connected to the control board 110 through the third wire-passing portion 400. By arranging the bracket and the wire-passing part on both sides of the box body, the internal space of the electrical box assembly is reasonably utilized, and the cables are prevented from occupying too much space, thereby providing more installation positions for other important components, optimizing the internal layout of the electrical box, and facilitating the compactness of the overall structure. By placing the first cable bundle (strong current cable) and the second cable bundle (weak current cable) on the first side and the second side of the box body respectively, and guiding them through the first wire-passing part and the second wire-passing part, the direct contact and overlap of strong and weak current wires in the traditional design are avoided, thereby significantly reducing electromagnetic interference and improving the electrical safety of the electrical box and the entire air-conditioning system.

[0032] The setting of the first bracket and the second bracket not only realizes the classification management of cables, but also simplifies the wiring path of the cables and shortens the length of the cables, which not only reduces the cost of wire materials, but also reduces the assembly cost and maintenance cost caused by the confusion of cables. The first bracket and the second bracket are respectively connected to the box body and the external structure (such as the moving part bracket and the chassis), forming a stable triangular support structure, which enhances the structural strength of the electrical box assembly, effectively prevents the forward tilt problem of the air conditioner due to unstable center of gravity during use, and improves the stability of the whole machine. The setting of the third wire passing part allows 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 to the control panel through the third wire passing part. This design greatly simplifies the assembly process of the electrical box assembly, and also facilitates later repairs and maintenance. The cables can be replaced or repaired individually without disassembling the entire electrical box.

[0033] Specifically, Figures 2 to 5 As shown, the electrical box assembly also includes: a first limiting component 500, which is arranged opposite to the first wire-passing portion 210, and a first limiting space is arranged between the first limiting component 500 and the first wire-passing portion 210; a second limiting component 600, which is arranged opposite to the second wire-passing portion 310, and a second limiting space is arranged between the second limiting component 600 and the second wire-passing portion 310. By setting the first limiting component 500 and the second limiting component 600, the wiring can be effectively fixed to prevent the shaking and misalignment of the wiring harness inside the electrical box. The limiting space between the limiting component and the wire-passing portion can effectively prevent the line from contacting and short-circuiting, especially between the strong current and weak current lines, reducing the fire hazard and improving the overall safety performance of the electrical box assembly.

[0034] The fixing function of the limiting component makes it easier to position and install the wiring harness during the assembly process, which reduces assembly time, improves production efficiency, and is conducive to large-scale production.

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

[0036] The first bracket 200 is provided with a first avoidance recess 220, which is in communication with the first wire-passing portion 210. The first limiting component 500 includes: a first limiting plate 510, at least part of which is disposed in the first avoidance recess 220. The first bracket 200 is equipped with a first avoidance recess 220, which is in communication with the first wire-passing portion 210, and is designed to better manage and protect the wiring harness passing through the bracket. The first limiting plate 510 in the first limiting component 500 is at least partially disposed in the first avoidance recess 220. Such a design can effectively limit the movement of the wiring harness in the bracket, prevent the wiring harness from loosening or being damaged due to vibration or external force, and also help keep the wiring harness neat, improve the internal aesthetics of the device, and reduce the difficulty of maintenance.

[0037] During the assembly process, the first avoidance recess 220 can also limit the first limiting plate 510. At the same time, the design of the first avoidance recess 220 makes the first limiting plate 510 closer to the first wire trough 211, so that the first limiting plate 510 enhances the limiting effect on the high-voltage harness 910 in the first wire trough 211.

[0038] The second bracket 300 is provided with a second avoidance recess 320, which is in communication with the second wire-passing portion 310, and the second limiting component 600 includes: a second limiting plate 610, at least part of which is disposed in the second avoidance recess 320. Similarly, the second bracket 300 is equipped with a second avoidance recess 320, which is in communication with the first wire-passing portion 210, and is designed to better manage and protect the wiring harness passing through the bracket. The second limiting plate 610 in the second limiting component 600 is at least partially disposed in the second avoidance recess 320. Such a design can effectively limit the movement of the wiring harness in the bracket, prevent the wiring harness from loosening or being damaged due to vibration or external force, and also help keep the wiring harness neat, improve the internal aesthetics of the equipment, and reduce the difficulty of maintenance.

[0039] During the assembly process, the second avoidance recess 320 can also limit the second limiting plate 610. At the same time, the design of the second avoidance recess 320 makes the second limiting plate 610 closer to the second wire trough 311, so that the second limiting plate 610 enhances the limiting effect on the low-voltage wire harness 920 in the second wire trough 311.

[0040] In the specific implementation process, the first limiting component 500 is arranged on the first side of the control board 110, and the first limiting component 500 includes a first connecting end and a first free end arranged oppositely, the first connecting end is connected to the control board 110, and the first free end extends toward the direction close to the first bracket 200; the second limiting component 600 is arranged on the second side of the control board 110, and the second limiting component 600 includes a second connecting end and a second free end arranged oppositely, the second connecting end is connected to the control board 110, and the second free end extends toward the direction close to the second bracket 300; the first limiting component 500 and the second limiting component 600 are an integrally formed structure with the control board 110. The limiting component and the control board are an integrally formed structure, which avoids the assembly of additional components, simplifies the assembly process of the electrical box assembly, reduces the assembly time, and reduces the failure rate caused by improper assembly, thereby improving the overall assembly efficiency and production quality. The design of the limiting component is directly implemented on the control board, and no additional space is required to install an independent limiting component, which makes the internal layout of the electrical box more compact, saves valuable space resources, and is conducive to the miniaturization and modular design of the electrical box assembly.

[0041] Furthermore, the box body 100 is provided with a third avoidance recess 120, and at least a portion of the first limiting component 500 is located in the third avoidance recess 120; the box body 100 is also provided with a through channel 130, and at least a portion of the second limiting component 600 passes through the through channel 130 and is opposite to the second wire passing portion 310. The introduction of the avoidance recess and the through channel provides a more precise guiding path for the cables, so that the first cable bundle and the second cable bundle can be fixed and passed more orderly, avoiding the disordered entanglement of the cables inside the electrical box, and improving the neatness and management efficiency of the cable layout. The design of the third avoidance recess 120 and the through channel 130 reasonably utilizes the internal space of the box body 100, not only providing an installation position for the first and second limiting components, but also ensuring that the cables can be connected to the control board in the shortest path, reducing space waste, and is conducive to the miniaturization and compactness of the electrical box assembly.

[0042] The combination of the limiter, avoidance notch, and through channel can not only fix the cable, but also enhance the mechanical strength of the electrical box assembly. The installation of the limiter 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 loose connection or damage caused by cable movement.

[0043] During the assembly process, the second limit plate 610 is first passed through the passage 130 to pre-position the control board 110. At this time, the second limit plate 610 extends into the second avoidance recess 320 to form a stopping effect on the second wire harness in the second wire passing groove 311. Then, the control board 110 continues to be completely placed into the box body 100. At this time, the first limit plate 510 extends into the third avoidance recess 120 and the first avoidance recess 220, so that the first limit plate 510 forms a stopping effect on the first wire harness in the first wire passing groove 211. At the same time, the control board 110 is also installed in the predetermined position in the box body 100 under the limiting effect of the third avoidance recess 120. Therefore, the first limit plate 510 and the second limit plate 610 not only play a stopping role for the first wire harness and the second wire harness, but also play a positioning role for the control board 110 when installing the control board 110.

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

[0045] In the embodiment provided in the present application, the first bracket 200 includes: a first frame 230 and a second frame 240 arranged opposite to each other, the first frame 230 and the second frame 240 are connected by a third frame 250, the first wire-passing portion 210 is arranged between the first frame 230, the second frame 240 and the third frame 250, and the first frame 230 is connected to the box body 100; the second frame 240 is provided with a first avoidance recess 220, at least part of the first limiting component 500 is located in the first avoidance recess 220 and is opposite to the third frame 250. In order to avoid the first frame 230 from interfering with the first limiting component 500, the height of the first frame 230 is smaller than that of the second frame 240, so that the first side surface of the box body 100 can also be used to limit the first wire harness.

[0046] The first wire-passing portion 210 is arranged between the first frame 230, the second frame 240 and the third frame 250 to form a polygonal cable channel. This design makes the cable layout more standardized, avoids the confusion and crossing of the cables, improves the neatness inside the electrical box, and facilitates maintenance and inspection. The first avoidance recess 220 on the second frame 240 cooperates with the first limiting component 500 to more firmly fix the cable, prevent the cable from loosening or being damaged due to vibration during the operation or transportation of the equipment, 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 bracket structure, enhances the bearing capacity and impact resistance of the electrical box assembly, especially when part of the first limiting component 500 is placed in the first avoidance recess 220 and opposite to the third frame 250, this structure can better fix the electrical box assembly to avoid forward tilting or shaking.

[0047] The second bracket 300 includes: a fourth frame 330 and a fifth frame 340 which are arranged opposite to each other, the fourth frame 330 and the fifth frame 340 are connected by a sixth frame 350, the second wire-passing portion 310 is arranged between the fourth frame 330, the fifth frame 340 and the sixth frame 350, and the fourth frame 330 is connected to the box body 100; the fifth frame 340 is provided with a second avoidance recess 320, at least part of the second position-limiting component 600 is located in the second avoidance recess 320 and is opposite to the sixth frame 350. In order to prevent the fourth frame 330 from interfering with the second position-limiting component 600, the height of the fourth frame 330 is smaller than that of the fifth frame 340, so that the second side surface of the box body 100 can also be used to limit the second wire harness.

[0048] The second wire-passing portion 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 machinery, but also a portion of the second limiting component 600 is arranged in the second avoidance recess 320 to ensure that the cable is fixed when passing through the second wire-passing portion to avoid cable wear or loosening due to vibration or movement. By arranging the second wire-passing portion 310 between the internal structures of the second bracket 300, the gap of the second bracket is fully utilized, effectively saving the space in the electrical box assembly, providing more installation space for other key components, and facilitating the optimization of the overall layout, making the electrical box assembly more compact.

[0049] Since the high-voltage cables and low-voltage cables are respectively guided through different wire-passing parts of the first bracket and the second bracket, this separate 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 present application also provides an air conditioner, including a body 700 and an electrical box assembly 800. The electrical box assembly 800 is disposed in the body 700, and the electrical box assembly 800 is the electrical box assembly of the above embodiment.

[0051] The electrical box assembly 800 significantly reduces electromagnetic interference by routing the strong and weak wires separately, isolating them using the first and second wire passing parts, and further fixing and managing the cables through the limit components, ensuring the precise operation of the air conditioner control system and improving the electromagnetic compatibility of the entire machine. The design of the electrical box assembly 800 effectively avoids the risks of line contact short circuit and fire. By separating the wiring and fixing the limit, it reduces the safety hazards caused by line failures and protects the safety of users' lives and property. The electrical box assembly 800 optimizes cable management and layout, simplifies the assembly process, facilitates maintenance and inspection, reduces the cost and time consumption of the air conditioner during production and maintenance, and improves work efficiency.

[0052] The air conditioner further includes: a chassis 710, which is arranged at the bottom of the body 700; a driving assembly 720, which includes a driving component 721 and a mounting bracket 722, wherein the driving component 721 is arranged on the mounting bracket 722 and is movably arranged relative to the mounting bracket 722, and the driving component 721 is drivingly connected to the air duct panel 730 of the air conditioner to drive the air duct panel 730 to move; the two ends of the first bracket 200 of the electrical box assembly 800 are respectively connected to the mounting bracket 722 and the chassis 710; and / or, the two ends of the second bracket 300 of the electrical box assembly 800 are respectively connected to the mounting bracket 722 and the chassis 710. The two ends of the first bracket 200 and the second bracket 300 are respectively connected to the mounting bracket 722 and the chassis 710, forming a stable triangular support structure. This structure can effectively disperse and carry the force generated by the drive assembly 720 when operating the air duct panel 730, avoid deformation or damage of the electrical box assembly 800 or the air duct panel 730 caused by uneven local force, and improve the overall structural stability and service life of the air conditioner. Since the bracket of the electrical box assembly 800 is directly connected to the mounting bracket 722 of the drive assembly 720, it helps to further isolate the strong and weak wires inside the electrical box. The cables connected to other components of the air conditioner are orderly managed through the first wire-passing portion 210 and the second wire-passing portion 310, reducing electromagnetic interference between cables and ensuring that the electrical system of the air conditioner can still maintain stable operation in a complex environment. The design of the bracket not only enhances the stability of the structure, but also provides space for cable management and positioning. During maintenance and overhaul, the drive assembly 720 and the electrical box assembly 800 can be easily accessed without major disassembly of the entire air conditioner, reducing maintenance costs and time. By connecting the first bracket 200 and the second bracket 300 to the mounting bracket 722 and the chassis 710, the internal space of the air conditioner is more reasonably utilized. This design avoids the possible interference when the electrical box assembly 800 is directly connected to the duct panel 730, provides more installation space for other key components, and optimizes the internal layout and design of the air conditioner.

[0053] The present application provides a new wiring method, in which the hot wire of the strong electric motor is routed through the left support groove (the first wire passing portion 210) of the electrical box component, and the weak wire stepper motor wire and fan wire are routed through the right support groove (the second wire passing portion 310) of the electrical box component, thereby reducing the electromagnetic interference ability of strong and weak electricity, solving the problem of a large number of strong and weak wire harnesses crossing and contacting each other, which is prone to fire, and is conducive to the normal operation of the air conditioner.

[0054] Specifically, Figure 6As shown, a first threading opening 260 is provided on the side of the first bracket 200, and a second threading opening 360 is provided on the side of the second bracket 300. The high-voltage harness 910 enters into the first wire groove 211 through the first threading opening 260, and then is connected to the control board 110 through the third wire passing portion 400. The low-voltage harness 920 enters into the second wire groove 311 through the second threading opening 360, and then is connected to the control board 110 through the third wire passing portion 400. The first threading opening 260 and the second threading opening 360 are respectively provided on the sides of the first bracket 200 and the second bracket 300, which is beneficial to avoid interference with the connection between the first bracket 200 and the second bracket 300 and the drive assembly 720. The first threading opening 260 is preferably provided on the first frame 230, and the second threading opening 360 is preferably provided on the fourth frame 330. The design of the wire threading port takes into consideration the rational use of space. By guiding the cables into specific wire troughs, such as the first wire trough 211 and the second wire trough 311, the internal layout of the electrical box assembly is made neater and more orderly, providing more space for the installation of other components.

They pass through the third wire passing part 400 of the electrical box and are inserted into the main board terminal.

[0066] like Figure 6 As shown, the wiring board 160 is fixed to the back of the sheet metal electrical box, and the connection harness 930 between the wiring board 160 and the mainboard passes through the electrical box rubber coil 161 from the back of the electrical box and is inserted into the mainboard terminal, without spatial intersection with the electric heating wire, the fan wire, and the stepper motor wire, which can reduce electromagnetic radiation interference. The wiring board 160 is also provided with a wire pressing plate 170, and the wire pressing plate 170 is provided with an insulating gasket 171, which contacts the cable to avoid short circuit.

[0067] The fireproof cover of the electrical box can catch the flames inside the electrical box when the mainboard catches fire accidentally, so as to prevent the flames from dripping onto the injection molded parts of the electrical box and catching fire.
