[0074] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0075] Reference below Figure 6-Figure 11 An electric control board assembly 20 according to an embodiment of the present invention is described.

[0076] like Figure 6 As shown, according to the electric control board assembly 20 of the electric control box component 100 of the first embodiment of the present invention, the electric control board assembly 20 is suitable for being arranged in the electric control box body 11 of the electric control box component 100, and the electric control box body 11 can accommodate and protect the electric control board assembly 20. The electric control board assembly 20 can be used to control the working status of other components.

[0077] The electric control board assembly 20 includes: an electric control board 2 and an electric control board bracket 3, and the electric control board 2 is arranged on the electric control board bracket 3. The electric control board bracket 3 and the electric control board 2 form an assembly, so that the overall rigidity and structural strength of the electric control board assembly 20 are greater than the rigidity and structural strength of the electric control board 2. When the electric control board 2 is replaced or repaired later, the electric control board bracket 3 and the electric control board 2 can be removed from the electric control box body 11 together, thereby reducing the risk of deformation and damage of the electric control board 2.

[0078] The electric control board 2 is arranged on the electric control board bracket 3, and the electric control board bracket 3 can fix and protect the electric control board 2, and can increase the overall structural strength and rigidity of the electric control board assembly 20. During the installation of the electric control board 2 in the electric control box body 11, the electric control board 2 can be first arranged on the electric control board bracket 3, and then the electric control board bracket 3 and the electric control board 2 are installed in the electric control box body 11 together, so as to avoid deformation or damage of the electric control board 2 during the installation process, and ensure the normal use of the electric control board 2. In addition, during the production and transportation of the electric control board 2, the produced electric control board 2 can be first arranged on the electric control board bracket 3, and then the assembly composed of the electric control board bracket 3 and the electric control board 2 can be transported, so as to avoid deformation or damage of the electric control board 2 during the production and transportation process, and ensure the normal use of the electric control board 2.

[0079] The electric control board bracket 3 is a plastic part, which can facilitate the production of the electric control board bracket 3 and reduce production costs. At the same time, when the electric control board 2 is arranged on the electric control board bracket 3, the overall rigidity and structural strength of the electric control board assembly 20 can be increased to prevent the electric control board 2 from being deformed and damaged during assembly or transportation.

[0080] According to the electric control board assembly 20 of the embodiment of the present invention, by arranging the electric control board 2 on the electric control board bracket 3, the electric control board bracket 3 can protect and fix the electric control board 2, increase the overall rigidity and structural strength of the electric control board assembly 20, avoid deformation and damage of the electric control board 2 during assembly or transportation, and ensure the normal use of the electric control board 2.

[0081] According to some embodiments of the present invention, referring to Figure 6 The electric control board 2 and the electric control board bracket 3 are detachably connected, which can facilitate the installation and removal of the electric control board 2, as well as the replacement and maintenance of the electric control board 2. In this way, when the electric control board 2 is damaged, the electric control board 2 can be replaced and repaired alone without replacing the electric control board bracket 3; when the electric control board bracket 3 is damaged, the electric control board bracket 3 can be replaced and repaired alone without replacing the electric control board 2, thereby ensuring the overall structural strength of the electric control board assembly 20 and reducing the maintenance cost.

[0082] According to some embodiments of the present invention, referring to Figure 8-Figure 9 The electric control board bracket 3 has a placement portion 32 for placing the electric control board 2, and the placement portion 32 can support the electric control board 2. The electric control board bracket 3 also has a limit buckle 31 that cooperates with the electric control board 2, and the limit buckle 31 and the placement portion 32 jointly limit the electric control board 2. When the electric control board 2 is arranged on the electric control board bracket 3, the electric control board 2 is located between the placement portion 32 and the limit buckle 31 of the electric control board bracket 3, and the limit buckle 31 and the placement portion 32 cooperate to jointly limit the electric control board 2, so as to realize the fixing of the electric control board 2 by the electric control board bracket 3 as a whole, and improve the stability of the electric control board 2 when in use.

[0083] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 , there are multiple limit buckles 31, which can make the electric control board bracket 3 fix the electric control board 2 more reliably and improve the stability of the electric control board 2 when in use. The limit buckles 31 are arranged at intervals along the circumference of the placement portion 32, and the limit buckles 31 cooperate with the outer edge of the electric control board 2, so that the electric control board 2 placed on the placement portion 32 can be more evenly stressed, avoiding the phenomenon of stress concentration, and improving the stability and reliability of the connection between the electric control board 2 and the electric control board bracket 3. In addition, the limit buckle 31 cooperates with the outer edge of the electric control board 2, which can facilitate the installation and removal of the electric control board 2, and at the same time can avoid the limit buckle 31 occupying more space on the electric control board 2, affecting the position distribution of components on the electric control board 2. For example, there can be six limit buckles 31, and two relatively long sides of the electric control board 2 can be respectively provided with two limit buckles 31, and two relatively short sides of the electric control board 2 can be respectively provided with one limit buckle 31, so that the distribution position of the limit buckle 31 can be more reasonable, and the overall force of the electric control board 2 can be more evenly stressed.

[0084] According to some embodiments of the present invention, referring to Fig.10 The limiting buckle 31 includes a first limiting portion 311 and a second limiting portion 312. The first limiting portion 311 is located on the outer peripheral side of the electric control board 2. The first limiting portion 311 has a limiting and fixing effect on the electric control board 2, which can prevent the electric control board 2 from deviating to the outer peripheral side of the placement portion 32. The placement portion 32 and the second limiting portion 312 are located on both sides of the electric control board 2 in the thickness direction. The second limiting portion 312 can abut against the electric control board 2, so that the electric control board 2 is closely attached to the placement portion 32. The second limiting portion 312 cooperates with the placement portion 32 to jointly limit the electric control board 2 in its own thickness direction. Therefore, the limiting buckle 31 cooperates with the placement portion 32 to improve the fixing effect of the electric control board bracket 3 on the electric control board 2 as a whole, and better ensure the stability of the electric control board 2 when in use.

[0085] According to some embodiments of the present invention, referring to Fig.10 The second limiting portion 312 has a guide surface 312a and a limiting surface 312b. The limiting surface 312b contacts the surface of the electric control board 2 in the thickness direction. The limiting surface 312b can cooperate with the placement portion 32 to jointly limit the electric control board 2 in its own thickness direction, thereby ensuring the stability of the electric control board 2. The guide surface 312a is connected to the side of the limiting surface 312b away from the placement portion 32. In the direction from the placement portion 32 to the electric control board 2, the guide surface 312a extends obliquely toward the direction away from the center of the electric control board 2. Such an arrangement enables the guide surface 312a to guide and guide the electric control board 2 during the installation process of the electric control board 2. The electric control board 2 is suitable for being installed on the electric control board bracket 3 under the guidance of the guide surface 312a.

[0086] When the electric control board 2 needs to be installed on the electric control board bracket 3, the electric control board 2 can be moved along the guide surface 312a of the second limiting portion 312 toward the placement portion 32 until the surface of the electric control board 2 in the thickness direction contacts the limiting surface 312b. The electric control board 2 is located between the second limiting portion 312 of the limiting buckle 31 and the placement portion 32, and the first limiting portion 311 is located on the outer peripheral side of the electric control board 2, so that the electric control board 2 is installed and fixed to the electric control board bracket 3.

[0087] For example, the second limiting portion 312 is further provided with a plurality of guide ribs 315, which are formed on a side of the second limiting portion 312 away from the first limiting portion 311. In the direction from the placement portion 32 to the electric control board 2, the guide ribs 315 extend obliquely in a direction away from the center of the electric control board 2, and the plurality of guide ribs 315 are arranged at intervals along the length direction of the electric control board 2. The guide ribs 315 form a guide surface 312a on a plane away from the placement portion 32 along the thickness direction of the electric control board 2. The guide ribs 315 can increase the structural strength of the limiting buckle 31, and ensure the fixing effect of the electric control board bracket 3 on the electric control board 2 as a whole.

[0088] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 , multiple limit buckles 31 include at least one first limit buckle 313 and at least one second limit buckle 314, for example, multiple limit buckles 31 include a first limit buckle 313 and a second limit buckle 314, or multiple limit buckles 31 include multiple first limit buckles 313 and a second limit buckle 314, or multiple limit buckles 31 include a first limit buckle 313 and multiple second limit buckles 314, or multiple limit buckles 31 include multiple first limit buckles 313 and multiple second limit buckles 314.

[0089] The first limit buckle 313 is a deformable elastic buckle, which can facilitate the installation and removal of the electric control board 2 and the electric control board bracket 3. The rigidity of the second limit buckle 314 is greater than that of the first limit buckle 313. The second limit buckle 314 can make the electric control board bracket 3 fix the electric control board 2 better, and make the electric control board bracket 3 fix the electric control board 2 more reliably. The first limit buckle 313 can facilitate the installation and removal of the electric control board 2 and the electric control board bracket 3.

[0090] The plurality of limit buckles 31 include at least one first limit buckle 313 and at least one second limit buckle 314, which can ensure the fixing effect of the electric control board bracket 3 on the electric control board 2 and facilitate the installation and removal of the electric control board 2 and the electric control board bracket 3. For example, the number of the first limit buckles 313 in the plurality of limit buckles 31 can be greater than the number of the second limit buckles 314, which can facilitate the installation and removal of the electric control board 2 and ensure the fixing effect of the electric control board bracket 3 on the electric control board 2. For example, there can be four first limit buckles 313 and two second limit buckles 314.

[0091] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 The first limiting buckle 313 and the second limiting buckle 314 are located on different sides of the electric control board 2, so that the installation and removal of the electric control board 2 can be facilitated. When installing the electric control board 2, a part of the edge of the electric control board 2 can be inserted between the second limiting buckle 314 and the placement portion 32, and then the electric control board 2 can be moved toward the placement portion 32, and the elastic deformation of the first limiting buckle 313 can be used to make the other part of the edge of the electric control board 2 stuck between the first limiting buckle 313 and the placement portion 32, so that the electric control board 2 can be installed on the electric control board bracket 3.

[0092] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 The electric control board 2 includes a first side 22, a second side 23, a third side 24 and a fourth side 25 arranged in sequence along the circumference of the electric control board 2, the second limiting buckle 314 is located on the first side 22, and the first limiting buckle 313 is located on the second side 23, the third side 24 and the fourth side 25. Such a configuration can facilitate the installation and removal of the electric control board 2. When installing the electric control board 2, the edge of the first side 22 of the electric control board 2 can be first inserted between the second limiting buckle 314 and the placement portion 32, and then the other side edges of the electric control board 2 can be moved in a direction close to the placement portion 32. By utilizing the elastic deformation of the first limiting buckle 313, the edge of the second side 23, the edge of the third side 24 and the edge of the fourth side 25 of the electric control board 2 are clamped between the first limiting buckle 313 and the placement portion 32, thereby installing the electric control board 2 to the electric control board bracket 3.

[0093] According to some embodiments of the present invention, the electric control board 2 is connected to the electric control board bracket 3 by a first fastener (not shown in the figure), which has a simple structure and is easy to assemble and disassemble, and can facilitate the installation and removal of the electric control board 2. Moreover, the electric control board 2 is connected to the electric control board bracket 3 by the first fastener, which can ensure the stability and reliability of the connection between the electric control board 2 and the electric control board bracket 3, and ensure the fixing effect of the electric control board bracket 3 on the electric control board 2. For example, the first fastener can be sequentially inserted into the electric control board bracket 3 and the electric control board 2, and then the electric control board bracket 3 and the electric control board 2 are fixed to the inner wall of the electric control box body 11.

[0094] According to some embodiments of the present invention, there are multiple first fasteners, which can make the electric control board bracket 3 fix the electric control board 2 more reliably and improve the stability of the electric control board 2 when in use. Multiple first fasteners are arranged at intervals along the circumference of the electric control board 2, which can make the electric control board 2 more evenly stressed, avoid stress concentration, and improve the stability and reliability of the connection between the electric control board 2 and the electric control board bracket 3.

[0095] According to some embodiments of the present invention, referring to Figure 8-Figure 9 and Fig.11 , the heat generating components 21 on the electric control board 2 are located on the same side of the electric control board 2. When the electric control board 2 is working, the heat generating components 21 generate a lot of heat, and if not handled in time, the heat generating components 21 will be damaged. Such a setting can be beneficial to the centralized heat dissipation treatment of the heat generating components 21 as a whole, and at the same time can facilitate the assembly between the heat generating components 21 and the electric control board 2, which is beneficial to improve the assembly efficiency of the heat generating components 21. The side of the electric control board 2 away from the heat generating components 21 has component pins, and the electric control board bracket 3 has a placement portion 32 for placing the electric control board 2, and a avoidance opening 321 for avoiding component pins is formed on the placement portion 32. The avoidance opening 321 can avoid the component pins to prevent the component pins from colliding or interfering with the placement portion 32 during assembly or transportation and being damaged, thereby improving the safety of the component pins and ensuring the normal use of the electric control board assembly 20.

[0096] According to some embodiments of the present invention, along the thickness direction of the electric control board 2 and in the direction in which the electric control board 2 is away from the heat generating component 21, the component pins do not extend beyond the electric control board bracket 3. This arrangement enables the electric control board bracket 3 to protect the component pins. During the assembly or transportation of the electric control board assembly 20, the component pins will not extend out of the avoidance opening 321 of the electric control board bracket 3 along the thickness direction of the electric control board 2, thereby maintaining a safe distance between the component pins and other structures, avoiding collision and damage of the component pins with other structures, and ensuring the normal use of the electric control board 2.

[0097] According to some embodiments of the present invention, referring to Figure 8-Figure 9The placement portion 32 includes a main rib plate 322 and a reinforcing rib plate 323. The main rib plate 322 is in a ring shape extending along the circumference of the electric control board 2. The reinforcing rib plate 323 is located on the inner circumference of the main rib plate 322 and is connected to the main rib plate 322. The reinforcing rib plate 323 is a plurality of reinforcing rib plates 323 and at least a portion of the plurality of reinforcing rib plates 323 intersects, for example, a portion of the plurality of reinforcing rib plates 323 intersects, or a plurality of reinforcing rib plates 323 intersect. The reinforcing rib plate 323 is connected to the main rib plate 322, which can better enhance the structural strength and rigidity of the placement portion 32, prevent the electric control board bracket 3 from being deformed during the assembly process, and ensure the fixing effect of the electric control board bracket 3 on the electric control board 2. It can also increase the overall structural strength of the electric control board assembly 20, better prevent the electric control board 2 from being deformed and damaged during the assembly and transportation process, and ensure the normal use of the electric control board 2.

[0098] The main rib plate 322 and the plurality of reinforcing rib plates 323 together define a plurality of avoidance openings 321 , thereby facilitating the formation of the avoidance openings 321 .

[0099] According to some embodiments of the present invention, referring to Figure 8-Figure 9 The electric control board bracket 3 is formed with a receiving groove 33, and the electric control board 2 is received in the receiving groove 33. The bottom wall of the receiving groove 33 constitutes a placement portion 32 for receiving the electric control board 2. The receiving groove 33 can receive and fix the electric control board 2. When the electric control board 2 is installed, the receiving groove 33 can be used to perform preliminary positioning of the electric control board 2, thereby facilitating the installation of the electric control board 2 and improving the assembly efficiency of the electric control board 2.

[0100] According to some embodiments of the present invention, referring to Figure 8-Figure 9 The bottom wall of the accommodating groove 33 is formed with a reinforcing rib 331, which can enhance the structural strength and rigidity of the placement portion 32, thereby improving the overall structural strength of the electric control board assembly 20, avoiding deformation or damage of the electric control board 2 during assembly or transportation, and ensuring the normal use of the electric control board assembly 20.

[0101] According to some embodiments of the present invention, referring to Figure 5 The electric control box body 11 includes a box body 111, and a receiving cavity 115 is formed in the box body 111. The heat generating components 21 on the electric control board 2 face the receiving cavity 115. The electric control board 2 is arranged on the electric control board bracket 3, and is installed in the electric control box body 11 through the electric control board bracket 3. Such an arrangement can facilitate the installation and removal of the electric control board 2 during the overall assembly, and at the same time ensure the overall structural strength of the electric control board assembly 20, and prevent the electric control board 2 from being deformed during installation.

[0102] According to some embodiments of the present invention, referring to Figure 4The electric control board bracket is detachably connected to the electric control box body 11, which can facilitate the installation and removal of the electric control board assembly 20 and the electric control box body 11, as well as the replacement and maintenance of the electric control board assembly 20. In this way, when the electric control board assembly 20 is damaged, the electric control board assembly 20 can be replaced and repaired alone without replacing the electric control box body 11; when the electric control box body 11 is damaged, the electric control board 2 box body can be replaced and repaired alone without replacing the electric control board assembly 20, thereby reducing the maintenance cost.

[0103] According to some embodiments of the present invention, the electric control board bracket is connected to the electric control box body 11 by a second fastener (not shown in the figure), which has a simple structure and is easy to assemble and disassemble, and can facilitate the installation and disassembly of the electric control board assembly 20. In addition, the electric control board assembly 20 is connected to the electric control box body 11 by the second fastener, which can ensure the stability and reliability of the connection between the electric control board assembly 20 and the electric control box body 11, and ensure the fixing effect of the electric control box body 11 on the electric control board assembly 20.

[0104] For example, there may be multiple second fasteners, which can make the electric control box body 11 fix the electric control board assembly 20 more reliably and improve the stability of the electric control board assembly 20 when in use. Multiple second fasteners are arranged at intervals along the circumference of the electric control board assembly 20, which can make the electric control board assembly 20 more evenly stressed, avoid stress concentration, and improve the stability and reliability of the connection between the electric control board assembly 20 and the electric control box body 11.

[0105] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 A wiring groove 34 is formed on the electric control board bracket 3, and the electric control wire harness connected to the electric control board 2 is suitable for routing along the wiring groove 34. The wiring groove 34 can accommodate and protect the electric control wire harness in the wiring groove 34. The wiring groove 34 can facilitate the arrangement of the electric control wire harness connected to the electric control board 2, so that the position setting of the electric control wire harness is more reasonable, avoid the safety problems caused by the messy placement of the electric control wire harness, and help improve the safety performance of the electric control board assembly 20. In addition, the wiring groove 34 is formed on the electric control board bracket 3, and the electric control wire harness of the electric control board 2 can be arranged after the electric control board 2 is set on the electric control board bracket 3, which can avoid arranging the electric control wire harness in the electric control box body 11, so that the arrangement of the electric control wire harness can be more convenient, saving assembly time and improving assembly efficiency.

[0106] According to some embodiments of the present invention, referring to Figure 6The electric control box body 11 includes a box body 111, a receiving cavity 115 is formed in the box body 111, and the opening direction of the wiring groove 34 faces the box body 111. This arrangement allows the electric control harness to be located between the wiring groove 34 and the box body 111, which is convenient for limiting the position of the electric control harness as a whole, and at the same time, the opening direction of the wiring groove 34 faces the side of the electric control board 2 where the heating component 21 is provided, thereby shortening the wiring path of the electric control harness, making the wiring of the electric control harness more convenient, and improving assembly efficiency.

[0107] According to some embodiments of the present invention, referring to Figure 4 The box body 111 is suitable for limiting the position of the electric control wiring harness together with the wiring groove 34. After the electric control board assembly 20 is installed in the electric control box body 11, the wiring groove 34 cooperates with the box body 111 to jointly limit the position of the electric control wiring harness, which can improve the overall fixing effect of the electric control wiring harness, ensure the stability of the electric control wiring harness in the electric control box body 11, avoid the problem of the electric control wiring harness escaping from the wiring groove 34 when in use, and ensure the normal connection of the electric control wiring harness.

[0108] According to some embodiments of the present invention, referring to Figure 6 The side of the electric control board 2 provided with the heating component 21 is the electric control board surface 26, and the height difference between the groove bottom 348 of the wiring groove 34 and the electric control board surface 26 is less than 10 mm. The electric control wire harness connected to the heating component 21 is first routed along the electric control board surface 26, then enters the wiring groove 34, and is routed to the outside of the electric control box body 11 through the wiring groove 34. The height difference between the groove bottom 348 of the wiring groove 34 and the electric control board surface 26 is less than 10 mm, which can make the routing of the electric control wire harness more convenient and shorten the routing path of the electric control wire harness.

[0109] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 The side wall of the wiring groove 34 is provided with a wire pressing buckle 343, which is used to limit the electric control wire harness in the wiring groove 34, and can prevent the electric control wire harness from escaping from the wiring groove 34, thereby ensuring the fixing effect of the wiring groove 34 on the electric control wire harness, and the position setting of the electric control wire harness is more reasonable. For example, there can be multiple wire pressing buckles 343, and multiple wire pressing buckles 343 can be arranged at intervals along the side wall of the wiring groove 34, so that the wiring groove 34 can have a better fixing effect on the electric control wire harness, and improve the safety performance of the electric control board assembly 20.

[0110] According to some embodiments of the present invention, the electric control harness includes a first electric control harness and a second electric control harness, the first electric control harness and the second electric control harness are routed separately, and the power of the heating component 21 connected to the first electric control harness is greater than the power of the heating component 21 connected to the second electric control harness. This arrangement can reduce electromagnetic interference between the first electric control harness and the second electric control harness, making the information transmission between the first electric control harness and the second electric control harness stable and reliable, and is also conducive to improving the reliability and safety of the electric control board assembly 20. Among them, the first electric control harness can be strong electricity, and the second electric control harness can be weak electricity.

[0111] According to some embodiments of the present invention, referring to Figure 7 The electric control board 2 has a first side 22 and a third side 24 which are arranged opposite to each other along the width direction.

[0112] At least part of the first electric control harness is routed along the first side 22 of the electric control board 2, for example, part of the first electric control harness is routed along the first side 22 of the electric control board 2, or all of the first electric control harness is routed along the first side 22 of the electric control board 2. At least part of the second electric control harness is routed along the third side 24 of the electric control board 2, for example, part of the second electric control harness is routed along the third side 24 of the electric control board 2, or all of the second electric control harness is routed along the third side 24 of the electric control board 2.

[0113] Alternatively, at least part of the first electric control harness is routed along the third side of the electric control board 2, for example, part of the first electric control harness is routed along the third side 24 of the electric control board 2, or all of the first electric control harness is routed along the third side 24 of the electric control board 2. At least part of the second electric control harness is routed along the first side of the electric control board 2, for example, part of the second electric control harness is routed along the first side 22 of the electric control board 2, or all of the second electric control harness is routed along the first side 22 of the electric control board 2.

[0114] In this way, the separate routing of the first electric control wiring harness and the second electric control wiring harness can be better achieved, thereby reducing the electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0115] According to some embodiments of the present invention, referring to Figure 5-Figure 7 The electric control board 2 has a second side 23 and a fourth side 25 that are oppositely arranged along the length direction, and a side wall of the electric control box body 11 adjacent to the second side 23 of the electric control board 2 is formed with a first wire outlet 113 and a second wire outlet 114 that are spaced apart along the width direction of the electric control board 2. The first wire outlet 113 may be adjacent to the first side 22 of the electric control board 2 in the width direction of the electric control board 2, and the second wire outlet 114 may be adjacent to the third side 24 of the electric control board 2 in the width direction of the electric control board 2.

[0116] The electric control harness routed along the first side 22 is suitable for being routed out through the first wire outlet 113, and the electric control harness routed along the third side 24 is suitable for being routed out through the second wire outlet 114. Thus, the routing of the electric control harness in the electric control box body 11 can be made more convenient, and the control connection between the electric control harness and other components outside the electric control box body 11 can also be facilitated, thereby improving the assembly efficiency of the whole machine.

[0117] Furthermore, the first wire outlet 113 and the second wire outlet 114 are spaced apart along the width direction of the electric control board 2, so that the electric control wire harness routed along the first side 22 and the electric control wire harness routed along the third side 24 are spaced apart when they are routed out, thereby reducing electromagnetic interference between different electric control wire harnesses.

[0118] According to some embodiments of the present invention, part of the first electric control wiring harness is routed along the fourth side 25 of the electric control board 2, or part of the second electric control wiring harness is routed along the fourth side 25 of the electric control board 2. Such an arrangement can make the routing of the first electric control wiring harness or the second electric control wiring harness adjacent to the fourth side 25 of the electric control board 2 more convenient, make the routing path of the electric control wiring harness more reasonable, avoid safety problems caused by messy routing of the electric control wiring harness, and help to improve the safety performance of the electric control board assembly 20.

[0119] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 The wiring groove 34 includes a first wiring groove 341 and a second wiring groove 342 located on opposite sides of the width direction of the electric control board 2. The first wiring groove 341 can be adjacent to the first side 22 of the electric control board 2, and the second wiring groove 342 can be adjacent to the third side 24 of the electric control board 2. The electric control wire harness routed along the first side 22 is suitable for routing along the first wiring groove 341, and the electric control wire harness routed along the third side 24 is suitable for routing along the second wiring groove 342. This arrangement can make the routing of the electric control wire harness in the electric control box body 11 more convenient, and at the same time, different electric control wire harnesses can be routed separately, so that the distance between the electric control wire harness routed along the first side 22 and the electric control wire harness routed along the third side 24 is longer, and electromagnetic interference between different electric control wire harnesses can be better avoided.

[0120] For example, the heat-generating component 21 connected to the electric control wiring harness routed along the first side 22 can be located on the side of the electric control board 2 close to the first wiring groove 341 in the width direction of the electric control board 2, and the heat-generating component 21 connected to the electric control wiring harness routed along the third side 24 can be located on the side of the electric control board 2 close to the second wiring groove 342 in the width direction of the electric control board 2. This can facilitate the routing of the first electric control wiring harness through the first wiring groove 341 and the routing of the second electric control wiring harness through the second wiring groove 342, thereby avoiding the need to increase the length of the first electric control wiring harness and the second electric control wiring harness, and saving costs.

[0121] According to some embodiments of the present invention, referring to Figure 6 and Figure 8 The wiring groove 34 includes a third wiring groove 347 . The third wiring groove 347 is located on the fourth side 25 of the electric control board 2 and is connected to the first wiring groove 341 .

[0122] Among them, the first electric control wiring harness is routed along the third wiring groove 347 and the first wiring groove 341, and the second electric control wiring harness is routed along the second wiring groove 342, which can facilitate the routing of the first electric control wiring harness and the second electric control wiring harness and make the routing paths of the first electric control wiring harness and the second electric control wiring harness more reasonable.

[0123] Alternatively, the first wiring groove 341 includes a first sub-wiring groove and a second sub-wiring groove which are arranged at intervals along the width direction of the electric control board 2, the first sub-wiring groove is connected to the third wiring groove 347, the second electric control wiring harness is suitable for routing along the third wiring groove 347 and the first sub-wiring groove, a part of the second electric control wiring harness is suitable for routing along the second sub-wiring groove 342 and another part of the second electric control wiring harness is suitable for routing along the second wiring groove 342. The first sub-wiring groove and the second sub-wiring groove are arranged at intervals, which can facilitate routing of the first electric control wiring harness and the second electric control wiring harness, and can separate the first electric control wiring harness from the second electric control wiring harness, thereby avoiding electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0124] Alternatively, the second wiring groove 342 includes a third sub-wiring groove and a fourth sub-wiring groove which are arranged at intervals along the width direction of the electric control board 2, part of the first electric control wiring harness is suitable for routing along the third wiring groove 347 and the first wiring groove 341, another part of the first electric control wiring harness is suitable for routing along the third sub-wiring groove, and the second electric control wiring harness is suitable for routing along the fourth sub-wiring groove. The third sub-wiring groove and the fourth sub-wiring groove are arranged at intervals, which can facilitate routing of the first electric control wiring harness and the second electric control wiring harness, and can separate the first electric control wiring harness from the second electric control wiring harness, thereby avoiding electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0125] Therefore, during installation, the routing paths of the first electric control wiring harness and the second electric control wiring harness can be reasonably selected according to the arrangement of the heat-generating components 21 on the electric control board 2, so that the routing of the first electric control wiring harness and the second electric control wiring harness can be more convenient, the routing of the electric control wiring harness can be more reasonable, and safety problems caused by messy routing of the electric control wiring harness can be avoided, thereby ensuring the safety performance of the electric control board assembly 20.

[0126] According to some embodiments of the present invention, referring to Figure 4-Figure 6 and Figure 8-Figure 9The side wall of the electric control box body 11 located on one side in the length direction of the electric control board 2 is formed with a first wire outlet 113 and a second wire outlet 114 spaced apart in the width direction of the electric control board 2. The first wire outlet 113 is opposite to and communicated with the first wiring groove 341, and the second wire outlet 114 is opposite to and communicated with the second wiring groove 342. The first electric control wire harness is suitable for being discharged through the first wire outlet 113, and the second electric control wire harness is suitable for being discharged through the second wire outlet 114. After the first electric control wire harness is accommodated in the first wiring groove 341 and is routed along the first wiring groove 341, it can be directly discharged from the first wire outlet 113. At the same time, after the second electric control wire harness is accommodated in the second wiring groove 342 and is routed along the second wiring groove 342, it can be directly discharged from the second wire outlet 114. The first wire outlet 113 and the second wire outlet 114 are spaced apart from each other along the width direction of the electric control board 2 , so as to better reduce electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0127] In addition, the first electric control harness and the second electric control harness are led out from the first wire outlet 113 and the second wire outlet 114 respectively, which can facilitate the control connection between other components outside the electric control box body 11 and the first electric control harness and the second electric control harness, thereby improving the assembly efficiency of the whole machine.

[0128] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 The electric control board bracket 3 has a placement portion 32 for placing the electric control board 2, and the placement portion 32 can support the electric control board 2. The electric control board bracket 3 also includes a wiring portion 35, and a wiring groove 34 is formed in the wiring portion 35, and the wiring portion 35 is located on the outer peripheral side of the placement portion 32. This arrangement can shorten the distance between the wiring portion 35 and the placement portion 32, and can facilitate the lead-out of the electric control wire harness of the electric control board 2 from the outer peripheral side of the placement portion 32 and accommodate it in the wiring groove 34 of the wiring portion 35, so that the overall arrangement of the electric control wire harness is more convenient, and the wiring layout of the electric control wire harness is more reasonable, avoiding safety problems caused by the messy placement of the electric control wire harness.

[0129] According to some embodiments of the present invention, the wiring portion 35 and the electric control box body 11 are suitable for being connected by a second fastener, which has a simple structure and is easy to assemble and disassemble, and can facilitate the installation and disassembly of the electric control board assembly 20. In addition, the wiring portion 35 and the electric control box body 11 are connected by the second fastener, which can ensure the stability and reliability of the connection between the wiring portion 35 and the electric control box body 11, and ensure the overall fixing effect of the wiring portion 35.

[0130] According to some embodiments of the present invention, a second fastener is provided on the side of the wiring trough 34 away from the placement portion 32, which can ensure the stability and reliability of the connection between the second fastener and the wiring portion 35, and make the second fastener closer to the wiring trough 34, thereby achieving a better fixing effect on the wiring trough 34, so that the electric control board bracket 3 can better fix the electric control wiring harness.

[0131] According to some embodiments of the present invention, a second fastener is provided on one side of the wiring trough 34 adjacent to the placement portion 32. The stability and reliability of the connection between the second fastener and the wiring portion 35 can be ensured, and the second fastener is close to the wiring trough 34, so as to achieve a better fixing effect on the wiring trough 34, so that the electric control board bracket 3 can better fix the electric control harness.

[0132] According to some embodiments of the present invention, referring to Figure 6 and Figure 8-Figure 9 When the second fastener is located on the side of the wiring groove 34 away from the placement portion 32, the outer side wall of the wiring groove 34 is recessed in the direction of the adjacent placement portion 32 to form a first avoidance groove 345 for avoiding the second fastener. When the second fastener is located on the side of the wiring groove 34 adjacent to the placement portion 32, the inner side wall of the wiring groove 34 is recessed in the direction away from the placement portion 32 to form a second avoidance groove 346 for avoiding the second fastener. The first avoidance groove 345 and the second avoidance groove 346 are both used to avoid the second fastener, which can prevent the second fastener from interfering with the wiring groove 34 and affecting the routing of the electric control harness in the wiring groove 34, thereby ensuring the smooth routing of the electric control harness in the wiring groove 34, and at the same time, the second fastener can be closer to the wiring groove 34, achieving a better fixing effect on the wiring groove 34. For example, there may be four second fasteners, two of which are located on the side of the wiring groove 34 away from the placement portion 32, and two of which are located on the side of the wiring groove 34 adjacent to the placement portion 32, which can better ensure the stability and reliability of the connection between the second fasteners and the wiring portion 35.
