[0037] Referring to Figures 1, 2 and 3, Figure 1 is a schematic diagram of the first structure of an electric control component provided in one embodiment of the present invention. Figure 2 is a schematic diagram of the second structure of an electric control component provided in one embodiment of the present invention. Figure 3 is a schematic diagram of a partial explosion of an electric control component provided in one embodiment of the present invention. The electric control component provided in one embodiment of the present invention includes a box body 100 and a main control board 510, the box body 100 has a accommodating cavity 110, and the peripheral side walls of the box body 100 are provided with a first wire passing port 140 and a second wire passing port 150 that are connected to the accommodating cavity 110; the main control board 510 is accommodated in the accommodating cavity 110, and the main control board 510 has electrically connected weak wires and strong wires, the weak wires are routed through the first wire passing port 140, and the strong wires are routed through the second wire passing port 150.

[0038] Specifically, in this application, the main control board 510 Pre-installed onThe box body 100 is modularly designed, and the weak-current and strong-current wires are respectively led out from the first wire opening 140 and the second wire opening 150 of the box body 100, so that the strong and weak electrical wiring are separated and do not interfere with each other, so that the electrical wiring can be reasonably arranged, thereby improving the assembly efficiency of the electronic control components, and improving the product performance and product electrical safety.

[0039] It should be noted that the voltage of strong wires is greater than that of weak wires, the voltage range of strong wires is greater than 24V, and the voltage range of weak wires is less than 24V.

[0040] Furthermore, the first wire opening 140 and the second wire opening 150 are located on opposite sides, thereby reducing interference between strong wires and weak wires and further improving safety performance.

[0041] Referring to Figures 2, 3 and 4, Figure 4 is a schematic diagram of the structure of a wire harness in an electric control assembly provided in an embodiment of the present invention. In one embodiment, the electric control assembly includes a wire harness 400, which is disposed outside the box body 100 and connected to the box body 100. The wire harness 400 has a wire harness hole 410, which is used to be sleeved on a strong wire to fix the strong wire.

[0042] Specifically, the wire material of the strong wire is relatively hard, and the strong wire is fixed to the box body 100 by the wire harness 400, so as to ensure that the strong wire has a reserved length between the wire harness hole 410 and the main control board 510 to buffer the force generated by pulling and directly transmit it to the main control board 510, thereby reducing the influence of stress pulling caused by bending of the strong wire on the main control board 510, improving the service life of the main control board 510, and thus improving the reliability of the electric control component. Among them, the number of strong wires is multiple, and each strong wire is inserted into the wire harness hole 410 and tied tightly.

[0043] Referring to Figures 2, 3, 4 and 5, Figure 5 is a schematic diagram of the structure of a motherboard seat in an electric control assembly provided by an embodiment of the present invention. In one embodiment, the box body 100 includes an extension plate 170, the extension plate 170 has a mounting hole 171, the cable harness 400 includes a connecting column 420, a cable harness segment 430 and a clamping portion 450, the cable harness segment 430 is connected to the connecting column 420, the cable harness hole 410 is located at the cable harness segment 430, the clamping portion 450 is connected to the connecting column 420, and the clamping portion 450 is configured to deform after being squeezed to pass through the mounting hole 171, and is used to abut against the side of the extension plate 170 away from the cable harness segment 430.

[0044] Specifically, when the connecting column 420 is inserted into the mounting hole 171, the clamping portion 450 will be deformed after being squeezed by the mounting hole 171, so that the clamping portion 450 and the connecting column 420 extend into the mounting hole 171, and after the clamping portion 450 extends out of the mounting hole 171, the clamping portion 450 restores its deformation and is able to abut against the side of the extension plate 170 away from the wiring harness segment 430, thereby limiting the connecting column 420 from falling out of the mounting hole 171 toward the side away from the wiring harness hole 410.

[0045] Furthermore, one end of the clamping portion 450 is connected to the connecting column 420, and the other end of the clamping portion 450 extends toward the harness segment 430, and there is a gap between the clamping portion 450 and the connecting column 420. When the hole wall of the mounting hole 171 squeezes the clamping portion 450, the side of the clamping portion 450 close to the harness segment 430 is deformed to be close to the connecting column 420, thereby reducing the radial dimension, which facilitates the connecting column 420 and the clamping portion 450 to extend into the mounting hole 171. After the clamping portion 450 passes through the mounting hole 171, the squeezing force disappears, and the end of the clamping portion 450 close to the harness segment 430 moves away from the connecting column 420 to restore the deformation, and can abut against the side of the extension plate 170 away from the harness hole 410 to limit the connecting column 420 from coming out of the mounting hole 171 to the side away from the harness hole 410. When the cable harness 400 needs to be disassembled, the clamping portion 450 can be manually squeezed to deform so that the connecting column 420 is disengaged from the mounting hole 171. Preferably, there are two clamping portions 450, which are disposed on opposite sides of the connecting column 420.

[0046] Referring to FIG. 2, FIG. 3, FIG. 4 and FIG. 5, in one embodiment, a baffle 440 is further provided on the connecting column 420, and the baffle 440 is located between the wire harness segment 430 and the clamping portion 450. The baffle 440 is used to abut against the side of the extension plate 170 close to the wire harness segment 430, thereby limiting the connecting column 420 from coming out relative to the mounting hole 171 toward the side close to the wire harness hole 410. That is, in the present application, by providing the clamping portion 450 and the baffle 440, the wire harness component 400 can be stably installed on the mounting hole 171, thereby improving the stability of fixing the strong wire.

[0047] 1 and 3 , in one embodiment, the box body 100 includes a detachably connected mainboard base 120 and a mainboard cover 130 , and when the mainboard base 120 and the mainboard cover 130 are connected, an accommodating cavity 110 is enclosed, and a first wire passing opening 140 is located between the mainboard base 120 and the mainboard cover 130 .

[0048] Specifically, when the mainboard seat 120 is connected to the mainboard cover 130, part of the structure of the mainboard seat 120 and part of the structure of the mainboard cover 130 surround a first wire passing opening 140, so that when the mainboard seat 120 is not connected to the mainboard cover 130, the first wire passing opening 140 has a notch, so that the weak-wire wires can be inserted into the first wire passing opening 140 through the notch of the first wire passing opening 140, thereby facilitating wiring and improving the efficiency of electrical wiring layout.

[0049] Referring to Figures 2 and 3, in one embodiment, the second wire passing opening 150 is located between the main board seat 120 and the main board cover 130. When the main board seat 120 is connected to the main board cover 130, part of the structure of the main board seat 120 and part of the structure of the main board cover 130 surround the second wire passing opening 150. Therefore, when the main board seat 120 is not connected to the main board cover 130, the second wire passing opening 150 has a notch, so that it is convenient for the high-voltage wire to extend into the second wire passing opening 150 through the notch of the second wire passing opening 150, thereby facilitating wiring and improving the efficiency of electrical wiring layout.

[0050] Referring to FIG. 3, FIG. 5 and FIG. 6, FIG. 6 is a top view of the main control board in the electric control assembly provided in one embodiment of the present invention. In one embodiment, the main board seat 120 has a fixing buckle 121, and the main control board 510 has a slot 512, and the slot 512 is used to engage with the fixing buckle 121, so that the main control board 510 is stably fixed on the main board seat 120, thereby improving the stability of the installation of the main board seat 120. Among them, the main board seat 120 has a plurality of spaced reinforcing ribs 560 on one side facing the main control board 510, so as to increase the strength of the main board seat 120.

[0051] Furthermore, one side of the mainboard base 120 has a limiting protrusion 123, which is located on a side away from the fixing buckle 121, and a limiting groove is formed between the limiting protrusion 123 and the bottom wall of the mainboard base 120. The edge area of ​​the main control board 510 extends into the limiting groove and abuts against the side wall of the limiting protrusion 123, thereby limiting the movement of the main control board 510 along its own height direction, and improving the stability of the installation of the main control board 510. Preferably, the number of the limiting protrusions 123 is at least two, and each limiting protrusion 123 is arranged at intervals along the length direction of the main control board 510.

[0052] 3, 5 and 6, in one embodiment, the main board base 120 has a fastening column 122, the main control board 510 has a through hole 511, and the electric control assembly further includes a fastener, which is passed through the through hole 511 and connected to the fastening column 122 to fix the main control board 510 on the main board base 120, thereby further improving the stability of the main board base 120 installed on the main board base 120. Preferably, the fastener is a common part such as a screw.

[0053] Referring to Figures 1, 3 and 5, in one embodiment, the electronic control component also includes a retaining rib 160, which is accommodated in the accommodating cavity 110 and connected to the main board seat 120. The retaining rib 160 is located on the side of the first wire passing opening 140 to abut against the weak wires passing through the first wire passing opening 140, so as to protect the weak wires and limit the movement of the weak wires, thereby avoiding wire compression when the main board seat 120 and the main board cover 130 are connected.

[0054] It should be noted that since the weak wires are soft and thin, they only need to be straightened and routed directly from the first outlet. There are multiple weak wires, and the weak wires can also be bundled into a wire harness by using a wire harness 400, a cable tie or a heat shrink sheath.

[0055] Referring to Figures 1, 3 and 7, Figure 7 is a schematic diagram of the structure of the air docking terminal in the electric control component provided by an embodiment of the present invention. In one embodiment, the electric control component further includes an air docking terminal 200, which is arranged outside the box body 100 and is electrically connected to the main control board 510. The electric control component further includes a stopper 300, which is connected to the box body 100 and connected to the air docking terminal 200 to fix the air docking terminal 200 on the box body 100, so that after the main control board 510 is installed, when an external display or other types of electric control components can be connected through the air docking terminal 200, the main board cover 130 does not need to be removed, that is, when the main control board 510 is pre-installed, the air docking control line electrically connected to the main control board 510 is led out and fixed on the main board cover 130, which is more convenient.

[0056] Referring to Figures 1, 3 and 7, in one embodiment, the limiting member 300 has a limiting hole 310, and a matching groove 320 is provided on the hole wall of the limiting hole 310. The docking terminal includes a main body 210 and a matching portion 220 connected to the main body 210. The matching portion 220 is configured to deform and fit into the limiting hole 310 after being squeezed, and be stopped by the groove wall of the matching groove 320.

[0057] Specifically, when the main body extends into the limiting hole 310, the mating part 220 will be deformed under the pressure of the limiting hole 310, so that the mating part 220 and the main body extend into the limiting hole 310, and when the mating part 220 moves to the mating groove 320, the squeezing force of the hole wall of the limiting hole 310 on the mating part 220 disappears, so that the mating part 220 restores its deformation and abuts against the groove wall of the mating groove 320, thereby limiting the main body from escaping from the limiting hole 310 in the opposite direction to the extending into the limiting hole 310, so as to stably fix the aerial docking terminal 200 on the box body 100.

[0058] Furthermore, the first end 223 of the matching portion 220 is connected to the body 210, and the second end 224 of the matching portion 220 opposite to the first end 223 is bent toward one side of the body 210, and there is a gap between the matching portion 220 and the body 210 to form a deformation space 250. When the hole wall of the limiting hole 310 squeezes the matching portion 220, the second end 224 of the matching portion 220 is deformed to get closer to the body, thereby reducing the radial dimension and facilitating insertion into the limiting hole 310. When the body drives the matching portion 220 to move to the matching groove 320, the squeezing force disappears, and the second end 224 of the matching portion 220 moves away from the body to restore the deformation, and can abut against the groove wall of the matching groove 320 to limit the escape.

[0059] Furthermore, the aerial docking terminal 200 includes a female terminal 230 and a sub-terminal 240 that are plugged together. The female terminal 230 is electrically connected to the main control board 510, and the sub-terminal 240 is electrically connected to the display. The matching portion 220 is provided on the female terminal 230. Through the plug-in matching of the female terminal 230 and the sub-terminal 240, the connection between the female terminal 230 and the sub-terminal 240 can be disconnected on the outside of the box body 100 without opening the inside of the box body 100, which is more convenient.

[0060] Referring to FIG. 1 , FIG. 3 and FIG. 7 , in one embodiment, the second end 224 has a first inclined surface 221 on a side away from the body 210, and the distance between the first inclined surface 221 and the body 210 gradually decreases in the direction from the first end 223 to the second end 224. The first inclined surface 221 is used to abut against the side wall of the avoidance groove, so that the mating portion 220 is subjected to a force away from the body 210, so that the second end 224 is stably stopped by the groove wall of the mating groove 320, thereby improving the stability of the aerial docking terminal 200 fixed to the box body 100. The first inclined surface 221 has an anti-slip groove.

[0061] Referring to Figures 1, 3 and 7, in one embodiment, a side of the first end 223 away from the main body 210 has a second inclined surface 222, and the second inclined surface 222 is used to abut against the hole wall of the limiting hole 310. In the direction from the first end 223 to the second end 224, the distance between the first inclined surface 221 and the main body 210 gradually expands, and the second inclined surface 222 is used to abut against the groove side wall of the limiting hole 310, so that the mating portion 220 is subjected to a force approaching the main body 210, so that when the aerial docking terminal 200 extends into the limiting hole 310, it is convenient for the mating portion 220 to deform, thereby improving the smoothness of the aerial docking terminal 200 extending into the limiting hole 310.

[0062] Referring to Figures 1, 3, 7 and 8, Figure 8 is a front view of a main board cover in an electric control assembly provided in an embodiment of the present invention. In one embodiment, a boss 260 is further provided on the body 210, and a protrusion 330 is provided on the hole wall of the limiting hole 310, and the protrusion 330 is used to abut against a side of the boss 260 away from the matching portion 220 to limit the main body from escaping from the limiting hole 310 in the direction of extending into the limiting hole 310, so as to stably fix the aerial docking terminal 200 on the box body 100. Among them, the boss 260 is provided on the terminal mother body.

[0063] Referring to Figures 1, 3 and 7, in one embodiment, the limit member 300 includes a first snap-fit ​​portion 340 and a second snap-fit ​​portion 350, and the first snap-fit ​​portion 340 and the second snap-fit ​​portion 350 are arranged at an interval, and the gap between the first snap-fit ​​portion 340 and the second snap-fit ​​portion 350 forms a matching groove 320, thereby reducing the quality and processing steps of the limit member 300 and improving the adaptability of the electronic control component.

[0064] Further, both ends of the first buckle portion 340 and the second buckle portion 350 are connected to the mainboard cover 130 to partially surround the limiting hole 310 with the mainboard cover 130, and the protrusion 330 is disposed on the second buckle portion 350. The first buckle portion 340 and the second buckle portion 350 have openings on one side away from the box body 100, so as to facilitate the cable 270 on the aerial docking terminal 200 to extend into the limiting hole 310, thereby improving assembly efficiency.

[0065] Furthermore, the electronic control component also includes a buckle 550, which is located on the side of the second buckle portion 350 away from the first buckle portion 340.
