[0075] The following describes in detail embodiments of the present disclosure, 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 intended only to explain the present disclosure and are not to be construed as limiting the present disclosure.

[0076] The electric control board assembly 20 according to an embodiment of the present disclosure will be described below with reference to FIG. 6 to FIG. 11 .

[0077] As shown in FIG6 , the electric control board assembly 20 of the electric control box component 100 according to the first embodiment of the present disclosure is adapted to be disposed within the electric control box body 11 of the electric control box component 100. 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 operating status of other components.

[0078] The electric control board assembly 20 includes an electric control board 2 and an electric control board bracket 3, with the electric control board 2 mounted on the electric control board bracket 3. The electric control board bracket 3 and the electric control board 2 form a single assembly, making the overall rigidity and structural strength of the electric control board assembly 20 greater than those of the electric control board 2. When the electric control board 2 is later replaced or repaired, the electric control board bracket 3 and the electric control board 2 can be removed from the electric control box 11 together, thereby reducing the risk of deformation or damage to the electric control board 2.

[0079] The electric control board 2 is mounted on the electric control board bracket 3. The electric control board bracket 3 can fix and protect the electric control board 2, thereby increasing 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 mounted on the electric control board bracket 3, and then the electric control board bracket 3 and the electric control board 2 can be installed into the electric control box body 11 together. This can prevent the electric control board 2 from being deformed or damaged during the installation process, thereby ensuring the normal use of the electric control board 2. Furthermore, during the production and transportation of the electric control board 2, the produced electric control board 2 can be first mounted on the electric control board bracket 3, and then the assembly consisting of the electric control board bracket 3 and the electric control board 2 can be transported. This can prevent the electric control board 2 from being deformed or damaged during the production and transportation process, thereby ensuring the normal use of the electric control board 2.

[0080] 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, thereby preventing the electric control board 2 from being deformed or damaged during assembly or transportation.

[0081] According to the electric control board assembly 20 of the embodiment of the present disclosure, by placing 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.

[0082] According to some embodiments of the present disclosure, referring to FIG6 , the electric control board 2 and the electric control board bracket 3 are detachably connected, which facilitates installation and removal of the electric control board 2, as well as replacement and repair of the electric control board 2. This arrangement allows the electric control board 2 to be replaced or repaired independently if it is damaged, without having to replace the electric control board bracket 3. Similarly, if the electric control board bracket 3 is damaged, the electric control board bracket 3 can be replaced or repaired independently without having to replace the electric control board 2. This reduces repair costs while maintaining the overall structural strength of the electric control board assembly 20.

[0083] According to some embodiments of the present disclosure, referring to Figures 8-9, 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 limiting buckle 31 that cooperates with the electric control board 2. The limiting buckle 31 and the placement portion 32 jointly limit the position of 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 limiting buckle 31 of the electric control board bracket 3. The limiting buckle 31 and the placement portion 32 cooperate to jointly limit the position of the electric control board 2, thereby achieving the fixation of the electric control board bracket 3 to the electric control board 2 as a whole, and improving the stability of the electric control board 2 when in use.

[0084] According to some embodiments of the present disclosure, referring to Figures 6 and 8-9, there are multiple limit buckles 31, which can make the fixation of the electric control board 2 by the electric control board bracket 3 more reliable, 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 is subjected to more uniform force, avoiding 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 buckles 31 cooperate with the outer edge of the electric control board 2 to facilitate the installation and removal of the electric control board 2, and at the same time avoid the limit buckles 31 occupying more space on the electric control board 2 and affecting the position distribution of components on the electric control board 2. For example, there can be six limit buckles 31. Two relatively longer sides of the electric control board 2 can be respectively provided with two limit buckles 31, and two relatively shorter sides of the electric control board 2 can be respectively provided with one limit buckle 31. This can make the distribution position of the limit buckles 31 more reasonable and make the overall force on the electric control board 2 more uniform.

[0085] According to some embodiments of the present disclosure, referring to FIG10 , the retaining buckle 31 includes a first retaining portion 311 and a second retaining portion 312. The first retaining portion 311 is located on the outer periphery of the electric control board 2. The first retaining portion 311 retains and secures the electric control board 2, preventing it from shifting toward the outer periphery of the placement portion 32. The placement portion 32 and the second retaining portion 312 are located on opposite sides of the electric control board 2 in the thickness direction. The second retaining portion 312 can abut against the electric control board 2, keeping it in close contact with the placement portion 32. The second retaining portion 312 cooperates with the placement portion 32 to limit the position of the electric control board 2 in the thickness direction. Thus, the retaining buckle 31 and the placement portion 32 cooperate to enhance the overall securing effect of the electric control board bracket 3 on the electric control board 2, better ensuring the stability of the electric control board 2 during use.

[0086] According to some embodiments of the present disclosure, referring to FIG10 , the second limiting portion 312 includes 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 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 in a direction away from the center of the electric control board 2. This configuration enables the guide surface 312a to guide and direct the electric control board 2 during installation. 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.

[0087] 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.

[0088] For example, the second retaining portion 312 is further provided with a plurality of guide ribs 315, formed on the side of the second retaining portion 312 away from the first retaining portion 311. In the direction from the placement portion 32 to the electronic control board 2, the guide ribs 315 extend obliquely away from the center of the electronic control board 2. The plurality of guide ribs 315 are spaced apart along the length of the electronic control board 2. The planar surface of the guide ribs 315, facing away from the placement portion 32 along the thickness direction of the electronic control board 2, forms a guide surface 312a. The guide ribs 315 enhance the structural strength of the retaining buckle 31, ensuring that the entire electronic control board bracket 3 secures the electronic control board 2.

[0089] According to some embodiments of the present disclosure, referring to Figures 6 and 8-9, multiple limiting buckles 31 include at least one first limiting buckle 313 and at least one second limiting buckle 314, for example, multiple limiting buckles 31 include a first limiting buckle 313 and a second limiting buckle 314, or multiple limiting buckles 31 include multiple first limiting buckles 313 and a second limiting buckle 314, or multiple limiting buckles 31 include a first limiting buckle 313 and multiple second limiting buckles 314, or multiple limiting buckles 31 include multiple first limiting buckles 313 and multiple second limiting buckles 314.

[0090] The first retaining buckle 313 is a deformable elastic buckle that facilitates installation and removal of the electronic control board 2 and the electronic control board bracket 3. The second retaining buckle 314 is more rigid than the first retaining buckle 313, which can better secure the electronic control board bracket 3 to the electronic control board 2, making the fixation of the electronic control board bracket 3 to the electronic control board 2 more reliable. The first retaining buckle 313 also facilitates installation and removal of the electronic control board 2 and the electronic control board bracket 3.

[0091] The multiple retaining buckles 31 include at least one first retaining buckle 313 and at least one second retaining buckle 314. These buckles ensure that the electric control board bracket 3 secures the electric control board 2 while facilitating installation and removal of the electric control board 2 from the electric control board bracket 3. For example, the number of first retaining buckles 313 in the multiple retaining buckles 31 can be greater than the number of second retaining buckles 314, facilitating installation and removal of the electric control board 2 while ensuring that the electric control board bracket 3 secures the electric control board 2. For example, there can be four first retaining buckles 313 and two second retaining buckles 314.

[0092] According to some embodiments of the present disclosure, referring to Figures 6 and 8-9, the first limiting buckle 313 and the second limiting buckle 314 are located on different sides of the electric control board 2. This arrangement facilitates the installation and removal of the electric control board 2. When installing the electric control board 2, a portion of the edge of the electric control board 2 can be first inserted between the second limiting buckle 314 and the placement portion 32. The electric control board 2 is then moved toward the placement portion 32. The elastic deformation of the first limiting buckle 313 allows the remaining portion of the edge of the electric control board 2 to be 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 disclosure, referring to Figures 6 and 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 sequentially along the circumference of the electric control board 2. The second retaining buckle 314 is located on the first side 22, and the first retaining buckle 313 is located on the second side 23, the third side 24, and the fourth side 25. This arrangement facilitates 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 retaining buckle 314 and the placement portion 32. The other side edges of the electric control board 2 are then moved toward the placement portion 32. The elastic deformation of the first retaining buckle 313 allows the edges of the second side 23, the third side 24, and the fourth side 25 of the electric control board 2 to be clamped between the first retaining buckle 313 and the placement portion 32, thereby securing the electric control board 2 to the electric control board bracket 3.

[0094] According to some embodiments of the present disclosure, the electric control board 2 is connected to the electric control board bracket 3 via a first fastener (not shown in the figure). This has a simple structure and is easy to assemble and disassemble, facilitating the installation and removal of the electric control board 2. Furthermore, the connection between the electric control board 2 and the electric control board bracket 3 by the first fastener ensures the stability and reliability of the connection between the electric control board 2 and the electric control board bracket 3, and ensures that the electric control board bracket 3 effectively secures the electric control board 2. For example, the first fastener can be sequentially inserted through the electric control board bracket 3 and the electric control board 2, and then both the electric control board bracket 3 and the electric control board 2 are secured to the inner wall of the electric control box body 11.

[0095] According to some embodiments of the present disclosure, multiple first fasteners are provided, which can more reliably secure the electric control board 2 to the electric control board bracket 3 and improve the stability of the electric control board 2 during use. The multiple first fasteners are arranged at intervals along the circumference of the electric control board 2, which can more evenly apply force to the electric control board 2, 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.

[0096] According to some embodiments of the present disclosure, referring to Figures 8-9 and 11 , the heat-generating components 21 on the electrical control board 2 are located on the same side of the electrical control board 2. When the electrical control board 2 is in operation, the heat-generating components 21 generate a significant amount of heat. Failure to promptly address this heat generation could damage the heat-generating components 21. This arrangement facilitates centralized heat dissipation of the heat-generating components 21 and facilitates assembly of the heat-generating components 21 with the electrical control board 2, thereby improving assembly efficiency. The electrical control board 2 has component pins on the side facing away from the heat-generating components 21. The electrical control board bracket 3 has a placement portion 32 for placing the electrical control board 2. The placement portion 32 has a clearance opening 321 formed therein for evacuating the component pins. The clearance opening 321 provides clearance for the component pins, preventing them from colliding or interfering with the placement portion 32 during assembly or transport, thereby improving the safety of the component pins and ensuring proper operation of the electrical control board assembly 20.

[0097] According to some embodiments of the present disclosure, component pins do not extend beyond the electrical control board bracket 3 along the thickness of the electrical control board 2 and in the direction away from the heat-generating component 21. This configuration allows the electrical control board bracket 3 to protect the component pins. During assembly or transportation of the electrical control board assembly 20, component pins do not extend beyond the clearance opening 321 of the electrical control board bracket 3 along the thickness of the electrical control board 2. This maintains a safe distance between the component pins and other structures, preventing damage from collisions with other structures and ensuring the normal operation of the electrical control board 2.

[0098] According to some embodiments of the present disclosure, referring to Figures 8 and 9 , the placement portion 32 includes a main rib 322 and a reinforcing rib 323. The main rib 322 is annular and extends along the circumference of the electronic control board 2. The reinforcing rib 323 is located on the inner circumference of the main rib 322 and is connected to the main rib 322. There are multiple reinforcing ribs 323, and at least some of the multiple reinforcing ribs 323 intersect. For example, some of the multiple reinforcing ribs 323 intersect, or all of the multiple reinforcing ribs 323 intersect. The connection between the reinforcing ribs 323 and the main rib 322 can further enhance the structural strength and rigidity of the placement portion 32, prevent deformation of the electronic control board bracket 3 during assembly, and ensure that the electronic control board bracket 3 effectively secures the electronic control board 2. Furthermore, the overall structural strength of the electronic control board assembly 20 can be increased, better preventing deformation and damage to the electronic control board 2 during assembly and transportation, and ensuring the normal use of the electronic control board 2.

[0099] The main ribs 322 and the plurality of reinforcing ribs 323 together define a plurality of avoidance openings 321 , facilitating the formation of the avoidance openings 321 .

[0100] According to some embodiments of the present disclosure, referring to Figures 8 and 9 , the electric control board bracket 3 is formed with a receiving groove 33. The electric control board 2 is received in the receiving groove 33. The bottom wall of the receiving groove 33 forms a placement portion 32 for the electric control board 2. The receiving groove 33 can accommodate and secure the electric control board 2. During installation, the receiving groove 33 can be used to initially position the electric control board 2, thereby facilitating installation and improving assembly efficiency.

[0101] According to some embodiments of the present disclosure, referring to Figures 8-9, a reinforcing rib 331 is formed on the bottom wall of the accommodating groove 33. The reinforcing rib 331 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, preventing the electric control board 2 from being deformed or damaged during assembly or transportation, and ensuring the normal use of the electric control board assembly 20.

[0102] According to some embodiments of the present disclosure, referring to FIG5 , the electric control box body 11 includes a box body 111 having a receiving cavity 115 formed therein. The heat-generating components 21 on the electric control board 2 face the receiving cavity 115. The electric control board 2 is mounted on an electric control board bracket 3 and installed within the electric control box body 11 via the electric control board bracket 3. This arrangement facilitates installation and removal of the electric control board 2 during overall assembly, while ensuring the overall structural strength of the electric control board assembly 20 and preventing deformation of the electric control board 2 during installation.

[0103] According to some embodiments of the present disclosure, referring to FIG4 , the electric control board bracket is detachably connected to the electric control box body 11, which facilitates the installation and removal of the electric control board assembly 20 from the electric control box body 11, as well as the replacement and repair of the electric control board assembly 20. This arrangement allows the electric control board assembly 20 to be replaced and repaired independently if it is damaged, without having to replace the electric control box body 11. Similarly, if the electric control box body 11 is damaged, the electric control board 2 can be replaced and repaired independently without having to replace the electric control board assembly 20, thereby reducing repair costs.

[0104] According to some embodiments of the present disclosure, the electric control board bracket is connected to the electric control box body 11 via a second fastener (not shown in the figure), resulting in a simple structure and easy assembly and disassembly, which can facilitate the installation and removal of the electric control board assembly 20. Furthermore, the connection between the electric control board assembly 20 and the electric control box body 11 by the second fastener 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 that the electric control box body 11 effectively fixes the electric control board assembly 20.

[0105] For example, multiple second fasteners can be provided to more reliably secure the electrical control box body 11 to the electrical control board assembly 20, improving the stability of the electrical control board assembly 20 during use. Multiple second fasteners spaced apart along the circumference of the electrical control board assembly 20 can more evenly distribute force on the electrical control board assembly 20, avoiding stress concentration and improving the stability and reliability of the connection between the electrical control board assembly 20 and the electrical control box body 11.

[0106] According to some embodiments of the present disclosure, referring to FIG6 and FIG8-9 , a wiring groove 34 is formed on the electric control board bracket 3, and the electric control wiring 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 wiring harness inside the wiring groove 34. The wiring groove 34 can facilitate the arrangement of the electric control wiring harness connected to the electric control board 2, making the position setting of the electric control wiring harness more reasonable, avoiding safety problems caused by the messy placement of the electric control wiring harness, and helping to 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 wiring 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 the arrangement of the electric control wiring harness inside the electric control box body 11, thereby making the arrangement of the electric control wiring harness more convenient, saving assembly time, and improving assembly efficiency.

[0107] According to some embodiments of the present disclosure, referring to FIG6 , the 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 trough 34 is toward the box body 111. This arrangement positions the electric control wiring harness between the wiring trough 34 and the box body 111, facilitating overall positioning of the electric control wiring harness. At the same time, the opening direction of the wiring trough 34 is directed toward the side of the electric control board 2 where the heat generating components 21 are provided, thereby shortening the wiring path of the electric control wiring harness, making wiring of the electric control wiring harness more convenient, and improving assembly efficiency.

[0108] According to some embodiments of the present disclosure, referring to FIG4 , the box body 111 is suitable for limiting the position of the electric control wiring harness together with the wiring trough 34. After the electric control board assembly 20 is installed in the electric control box body 11, the wiring trough 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 falling out of the wiring trough 34 during use, and ensure the normal connection of the electric control wiring harness.

[0109] According to some embodiments of the present disclosure, referring to FIG6 , the side of the electric control board 2 on which the heat-generating components 21 are provided is the electric control board surface 26, and the height difference between the bottom 348 of the wiring trough 34 and the electric control board surface 26 is less than 10 mm. The electric control wiring harness connected to the heat-generating components 21 is first routed along the electric control board surface 26, then enters the wiring trough 34, and is routed through the wiring trough 34 to the outside of the electric control box body 11. The height difference between the bottom 348 of the wiring trough 34 and the electric control board surface 26 is less than 10 mm, which makes the routing of the electric control wiring harness more convenient and facilitates shortening the routing path of the electric control wiring harness.

[0110] According to some embodiments of the present disclosure, referring to Figures 6 and 8-9, the sidewalls of the wiring trough 34 are provided with wire clamps 343. The wire clamps 343 are used to confine the electric control wiring harness within the wiring trough 34, thereby preventing the electric control wiring harness from escaping from the wiring trough 34, thereby ensuring the effective fixation of the electric control wiring harness by the wiring trough 34 and making the positioning of the electric control wiring harness more reasonable. For example, there may be multiple wire clamps 343, and the multiple wire clamps 343 may be spaced along the sidewalls of the wiring trough 34, thereby improving the fixing effect of the wiring harness by the wiring trough 34 and enhancing the safety performance of the electric control board assembly 20.

[0111] According to some embodiments of the present disclosure, the electric control wiring harness includes a first electric control wiring harness and a second electric control wiring harness. The first electric control wiring harness and the second electric control wiring harness are routed separately, and the power of the heat-generating component 21 connected to the first electric control wiring harness is greater than the power of the heat-generating component 21 connected to the second electric control wiring harness. This arrangement can reduce electromagnetic interference between the first and second electric control wiring harnesses, ensure stable and reliable information transmission between the first and second electric control wiring harnesses, and also help improve the reliability and safety of the electric control board assembly 20. The first electric control wiring harness can be high-voltage, and the second electric control wiring harness can be low-voltage.

[0112] According to some embodiments of the present disclosure, referring to FIG. 7 , the electric control board 2 has a first side 22 and a third side 24 that are oppositely disposed along the width direction.

[0113] At least a portion of the first electric control wiring harness is routed along the first side 22 of the electric control board 2, for example, the first electric control wiring harness is partially routed along the first side 22 of the electric control board 2, or the first electric control wiring harness is entirely routed along the first side 22 of the electric control board 2. At least a portion of the second electric control wiring harness is routed along the third side 24 of the electric control board 2, for example, the second electric control wiring harness is partially routed along the third side 24 of the electric control board 2, or the second electric control wiring harness is entirely routed along the third side 24 of the electric control board 2.

[0114] Alternatively, at least a portion of the first electric control wiring harness is routed along the third side of the electric control board 2, for example, the first electric control wiring harness is partially routed along the third side 24 of the electric control board 2, or the first electric control wiring harness is entirely routed along the third side 24 of the electric control board 2. At least a portion of the second electric control wiring harness is routed along the first side of the electric control board 2, for example, the second electric control wiring harness is partially routed along the first side 22 of the electric control board 2, or the second electric control wiring harness is entirely routed along the first side 22 of the electric control board 2.

[0115] In this way, the first electric control wiring harness and the second electric control wiring harness can be routed separately, thereby reducing electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0116] According to some embodiments of the present disclosure, referring to Figures 5 to 7, the electric control board 2 has a second side 23 and a fourth side 25 disposed opposite each other along the length direction. A sidewall of the electric control box body 11 adjacent to the second side 23 of the electric control board 2 is formed with a first cable outlet 113 and a second cable outlet 114 spaced apart along the width direction of the electric control board 2. The first cable 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 cable 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.

[0117] The electric control wiring harness routed along the first side 22 is suitable for exiting through the first wiring outlet 113, and the electric control wiring harness routed along the third side 24 is suitable for exiting through the second wiring outlet 114. This makes it easier to route the electric control wiring harness within the electric control box 11, and also facilitates control connections between the electric control wiring harness and other components outside the electric control box 11, thereby improving the assembly efficiency of the entire machine.

[0118] In addition, 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 wiring harness routed along the first side 22 and the electric control wiring harness routed along the third side 24 are spaced apart when they are routed out, thereby reducing electromagnetic interference between different electric control wiring harnesses.

[0119] According to some embodiments of the present disclosure, 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. This 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 improve the safety performance of the electric control board assembly 20.

[0120] According to some embodiments of the present disclosure, referring to FIG6 and FIG8-9 , the wiring trough 34 includes a first wiring trough 341 and a second wiring trough 342 located on opposite sides of the width direction of the electric control board 2. The first wiring trough 341 may be adjacent to the first side 22 of the electric control board 2, and the second wiring trough 342 may be adjacent to the third side 24 of the electric control board 2. The electric control wiring harness routed along the first side 22 is suitable for routing along the first wiring trough 341, and the electric control wiring harness routed along the third side 24 is suitable for routing along the second wiring trough 342. This arrangement can make routing of the electric control wiring harness within the electric control box body 11 more convenient, and can also achieve separate routing of different electric control wiring harnesses, so that the distance between the electric control wiring harness routed along the first side 22 and the electric control wiring harness routed along the third side 24 is greater, thereby better avoiding electromagnetic interference between the different electric control wiring harnesses.

[0121] For example, the heating 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 heating 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, thereby facilitating the routing of the first electric control wiring harness from the first wiring groove 341 and the routing of the second electric control wiring harness from the second wiring groove 342, thereby avoiding the long lengths of the first electric control wiring harness and the second electric control wiring harness, and saving costs.

[0122] According to some embodiments of the present disclosure, referring to FIG. 6 and FIG. 8 , the wiring trough 34 includes a third wiring trough 347 . The third wiring trough 347 is located on the fourth side 25 of the electric control board 2 and is connected to the first wiring trough 341 .

[0123] 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, making the routing paths of the first electric control wiring harness and the second electric control wiring harness more reasonable.

[0124] Alternatively, the first wiring trough 341 includes a first sub-wiring trough and a second sub-wiring trough spaced apart along the width direction of the electric control board 2. The first sub-wiring trough is connected to the third wiring trough 347. The second electric control wiring harness is adapted to be routed along the third wiring trough 347 and the first sub-wiring trough. A portion of the second electric control wiring harness is adapted to be routed along the second sub-wiring trough 342, and another portion of the second electric control wiring harness is adapted to be routed along the second wiring trough 342. The spacing between the first sub-wiring trough and the second sub-wiring trough facilitates routing of the first and second electric control wiring harnesses while separating the first and second electric control wiring harnesses, thereby preventing electromagnetic interference between the first and second electric control wiring harnesses.

[0125] Alternatively, the second wiring trough 342 includes a third sub-routing trough and a fourth sub-routing trough spaced apart along the width of the electric control board 2. A portion of the first electric control wiring harness is adapted to be routed along the third wiring trough 347 and the first wiring trough 341. Another portion of the first electric control wiring harness is adapted to be routed along the third sub-routing trough, and a portion of the second electric control wiring harness is adapted to be routed along the fourth sub-routing trough. The spacing between the third and fourth sub-routing troughs facilitates routing of the first and second electric control wiring harnesses while separating the first and second electric control wiring harnesses, thereby preventing electromagnetic interference between the first and second electric control wiring harnesses.

[0126] 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 heating 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 the safety problems caused by the messy routing of the electric control wiring harness can be avoided, thereby ensuring the safety performance of the electric control board assembly 20.

[0127] According to some embodiments of the present disclosure, with reference to Figures 4 to 6 and Figures 8 to 9, a side wall of the electric control box body 11 located on one side in the longitudinal direction of the electric control board 2 is formed with a first wire outlet 113 and a second wire outlet 114 spaced apart along the width direction of the electric control board 2. The first wire outlet 113 is opposite to and communicates with the first wiring trough 341, and the second wire outlet 114 is opposite to and communicates with the second wiring trough 342. The first electric control wiring harness is suitable for being routed out through the first wire outlet 113, and the second electric control wiring harness is suitable for being routed out through the second wire outlet 114. After the first electric control wiring harness is accommodated in the first wiring trough 341 and routed along the first wiring trough 341, it can be routed out directly from the first wire outlet 113. At the same time, after the second electric control wiring harness is accommodated in the second wiring trough 342 and routed along the second wiring trough 342, it can be routed out directly from the second wire outlet 114. The first wire outlet 113 and the second wire outlet 114 are spaced apart along the width direction of the electric control board 2 , thereby better reducing electromagnetic interference between the first electric control wiring harness and the second electric control wiring harness.

[0128] 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.

[0129] According to some embodiments of the present disclosure, referring to FIG6 and FIG8-9 , 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. 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 extraction of the electric control wiring 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, thereby making the overall arrangement of the electric control wiring harness more convenient, making the wiring layout of the electric control wiring harness more reasonable, and avoiding safety problems caused by the messy placement of the electric control wiring harness.

[0130] According to some embodiments of the present disclosure, the wiring portion 35 is adapted to be connected to the electrical control box body 11 via a second fastener, resulting in a simple structure and easy assembly and disassembly, thereby facilitating the installation and removal of the electrical control board assembly 20. Furthermore, the wiring portion 35 is connected to the electrical control box body 11 via the second fastener, thereby ensuring the stability and reliability of the connection between the wiring portion 35 and the electrical control box body 11 and ensuring the overall fixing effect of the wiring portion 35.

[0131] According to some embodiments of the present disclosure, 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.

[0132] According to some embodiments of the present disclosure, a second fastener is provided on one side of the wiring trough 34 adjacent to the placement portion 32. This ensures the stability and reliability of the connection between the second fastener and the wiring portion 35, and allows the second fastener to be closer to the wiring trough 34, thereby effectively securing the wiring trough 34 and better securing the electric control wiring harness to the electric control board bracket 3.

[0133] According to some embodiments of the present disclosure, referring to Figures 6 and 8-9, when the second fastener is located on the side of the wiring trough 34 away from the placement portion 32, the outer wall of the wiring trough 34 is recessed toward the placement portion 32 to form a first escape groove 345 for circumventing the second fastener. When the second fastener is located on the side of the wiring trough 34 adjacent to the placement portion 32, the inner wall of the wiring trough 34 is recessed toward the placement portion 32 to form a second escape groove 346 for circumventing the second fastener. Both the first escape groove 345 and the second escape groove 346 are designed to circumvent the second fastener, preventing interference between the second fastener and the wiring trough 34 and affecting the routing of the electronic control wiring harness within the wiring trough 34. This ensures smooth routing of the electronic control wiring harness within the wiring trough 34 and keeps the second fastener closer to the wiring trough 34, effectively securing the wiring trough 34. For example, there can 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.

[0136] According to the electric control box component 100 of the embodiment of the present disclosure, by setting the above-mentioned electric control board assembly 20 and by setting 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.

[0137] According to some embodiments of the present disclosure, referring to Figures 3 and 4 , the electric control box assembly 100 includes a heat sink 12, which is disposed outside the electric control box body 11. The heat generating components 21 on the electric control board 2 face the heat sink 12. This arrangement shortens the distance between the heat generating components 21 and the heat sink 12, thereby improving the heat dissipation efficiency of the heat sink 12 for the electric control board assembly 20 and ensuring the normal operation of the electric control board assembly 20.

[0138] The following describes an electric control box component 100 according to an embodiment of the present disclosure with reference to FIG. 3 to FIG. 11 .

[0140] The radiator 12 is disposed outside the electrical control box 11 and connected to the electrical control box 11. The radiator 12 dissipates heat and cools the electrical control box 11. The radiator 12 is disposed within the box body 111 and is integrally formed therewith, thereby enhancing the heat dissipation effect of the box body 111. The radiator 12 may include a plurality of fins 121 spaced apart along the width of the electrical control box 10. Each fin 121 extends along the length of the electrical control box 10, and adjacent fins 121 define a heat dissipation channel extending along the length of the electrical control box 10.

The first electric control wiring harness is for high-voltage power, while the second electric control wiring harness is for low-voltage power.

[0142] The electric control board bracket 3 is recessed near the center toward one side of the thickness direction of the electric control board bracket 3 to form a placement portion 32. The placement portion 32 is used to place the electric control board 2. The first fastener can pass through the electric control board 2 and the placement portion 32 to connect the electric control board 2 to the electric control board bracket 3. The placement portion 32 includes a main rib 322 and a reinforcing rib 323. The main rib 322 is annular and extends along the circumference of the electric control board 2. There are multiple reinforcing ribs 323, and at least some of the multiple reinforcing ribs 323 intersect. The reinforcing ribs 323 are located on the inner circumference of the main rib 322 and the reinforcing ribs 323 are connected to the main rib 322. The main rib 322 and the multiple reinforcing ribs 323 together define a plurality of avoidance openings 321. The avoidance openings 321 are used to avoid component pins, which can prevent the component pins from colliding with other structures and being damaged, affecting the normal use of the electric control board 2.
