[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

This is merely for ease of description and does not indicate or imply that the device or component described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting the utility model. In addition, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense, for example, to refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0037] Based on the problem pointed out in the background art that the existing electric control box has a small space and a large number of wire harnesses, which makes it difficult to plug and organize the wire harnesses, and they are prone to mutual interference, thus affecting the assembly efficiency. The utility model provides an electric control box body, an electric control box, and an air conditioner. By providing different wiring channels inside the electric control box body, different types of wire harnesses can be fixed and organized separately, making the wiring of the wire harness more regular and organized, facilitating the plugging and organization of the wire harnesses, optimizing the internal space, and improving the assembly efficiency.

[0038] Specifically, if Figure 1 and Figure 2 As shown, the utility model provides a box body of an electric control box, which includes a vertical plate 1 and a partition 2 arranged on the vertical plate 1, and the partition 2 divides the inner side of the vertical plate 1 into: an electric control compartment, which is used to install an electric control unit; a wire harness compartment, which is used to arrange various wire harnesses, and the wire harness compartment is connected to the electric control compartment and the external space of the box body at the same time, so that the wire harness can connect the electric control unit with the external functional unit, and a limiting structure is provided in the wire harness compartment, which can classify and fix different wire harnesses to prevent interference between the wire harnesses.

[0039] Exemplarily, a base is also provided at the bottom of the vertical plate 1. The vertical plate 1 and the base are integrally formed to form the inner shell of the box. The partition 2 extends in the vertical direction to divide the interior of the box into an electric control compartment and a wiring harness compartment arranged side by side in the horizontal direction. The electric control unit (such as electrical components such as circuit boards) is fixed to the part of the vertical plate 1 located in the electric control compartment, and the wiring harness is fixed to the part of the vertical plate 1 located in the wiring harness compartment. The partition 2 has several notches or through holes connecting the electric control compartment and the wiring harness compartment, so that various wiring harnesses can pass through to realize the connection between the wiring harness and the circuit board. A notch or through hole connecting the wiring harness compartment and the external space is also provided on one side of the vertical plate 1 located at the wiring harness compartment, so that the wiring harness can pass through and be electrically connected to the external functional unit.

[0040] In the wiring harness bin, the limiting structure can be set as several wiring channels composed of several grooves, clamps or pipes and other limiting structures, which can classify, fix and constrain the wiring harnesses so that different types of wiring harnesses can be arranged in the corresponding wiring channels. Compared with the messy distribution of wiring harnesses in traditional boxes, the box in this solution makes the distribution of wiring harnesses clearer and more regular, avoiding mutual interference between wiring harnesses. At the same time, the wiring harnesses can be easily connected without a large installation operation space, which greatly saves the time for wiring harness arrangement and connection, and improves the overall assembly efficiency and space utilization.

[0041] It should be noted that the position of the limiting structure and the wiring path can be flexibly set as needed, as long as the wiring harness can be organized and classified. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0042] Preferably, if Figure 1 and Figure 2 As shown, the limiting structure of the utility model includes: a first wiring channel, the two ends of the first wiring channel are respectively connected to the external space of the electric control compartment and the box body, and are used to limit the power line; a second wiring channel, the two ends of the second wiring channel are respectively connected to the external space of the electric control compartment and the box body, and are used to limit other wiring harnesses; a third wiring channel, the two ends of the third wiring channel are respectively connected to the external space of the electric control compartment and the box body, and are used to limit the press line.

[0043] The first routing channel, the second routing channel and the third routing channel are relatively independent, do not cross each other, and maintain a certain distance between them.

[0044] Since the power line is used to supply power to the electronic control module and the press line is used to transmit signals from the electronic control module to the press, the current intensity in these two types of wiring harnesses is relatively large. Arranging them together will produce strong electromagnetic interference, affecting the stability of current and signal transmission. Therefore, the two are separated and fixed through the first routing channel and the third routing channel respectively. Other wiring harnesses mainly include motor wires, four-way valve wires, etc. This type of wiring harness is allowed to be arranged together, which is conducive to saving space and cost.

[0045] Through this setting, three independent wiring channels can be used to restrain and fix the power cord, press wire and other wiring harnesses separately, preventing the messy distribution between the wiring harnesses, effectively reducing the intensity of electromagnetic interference, and making the plugging and organization of the wiring harness easier and faster.

[0046] Preferably, if Figure 1 and Figure 2As shown, the first wiring channel of the present invention includes: a first wiring opening 31, the first wiring opening 31 is set on the partition 2, connecting the electric control compartment and the wiring harness compartment; a second wiring opening 32, the second wiring opening 32 is set on the riser 1 in the part inside the electric control compartment, connecting the wiring harness compartment and the external space of the box; a first wiring groove 41, the first end of the first wiring groove 41 is connected to the first wiring opening 31, and the second end of the first wiring groove 41 extends to the vicinity of the second wiring opening 32; and / or the second wiring channel includes: a third wiring opening 33 , the third wiring opening 33 is arranged on the partition 2, connecting the electric control compartment and the wiring harness compartment; the second wiring groove 42, the first end of the second wiring groove 42 is connected to the third wiring opening 33, and the second end of the second wiring groove 42 extends to the vicinity of the second wiring opening 32; and / or the third wiring channel includes: a fourth wiring opening 34, the fourth wiring opening 34 is arranged on the partition 2, connecting the electric control compartment and the wiring harness compartment; the fifth wiring opening 35, the fifth wiring opening 35 is arranged on the part of the vertical plate 1 located in the electric control compartment, connecting the wiring harness compartment and the external space of the box.

[0047] Among them, the first wiring opening 31, the third wiring opening 33 and the fourth wiring opening 34 are all notches set on the partition 2, and the second wiring opening 32 and the fifth wiring opening 35 are all notches set on the vertical plate 1. This setting can not only limit the wiring harness, but also facilitate the rapid disassembly and replacement of the wiring harness.

[0048] The first wiring groove 41 is distributed along the edge of the riser 1 , and the second wiring groove 42 is located inside the first wiring groove 41 . The two are relatively independent and do not cross each other.

[0049] In addition, the above structure can not only realize the classification and fixation of the wire harness, but also greatly simplify the limiting structure in the wire harness bin, shorten the wiring distance, and make the distribution of the wire harness more regular and orderly.

[0050] Preferably, if Figure 1 and Figure 2 As shown, the positions of the first wiring groove 41 and the second wiring groove 42 of the present invention are both higher than the position of the second wiring opening 32 ; and / or the position of the fourth wiring opening 34 is higher than the position of the fifth wiring opening 35 .

[0051] Since the second wiring opening 32 and the fifth wiring opening 35 are both connected to the external space, when rainwater enters the air conditioner, it is easy to enter the box through the second wiring opening 32 and the fifth wiring opening 35 along the wiring harness, causing damage to the electronic control unit.

[0052] Therefore, the second wiring opening 32 and the fifth wiring opening 35 are both arranged at the lower part of the box, so that the second wiring opening 32 becomes the lowest point on the wiring path of the power cord and other wiring harnesses, ensuring that the part of the power cord and other wiring harnesses located in the box is higher than the position of the second wiring opening 32, so as to form a return bend at the second wiring opening 32, and prevent external water from flowing through the second wiring opening 32 along the power cord or other wiring harnesses into the box; similarly, the fifth wiring opening 35 is made the lowest point on the wiring path of the press line, ensuring that the part of the press line located in the box is higher than the fifth wiring opening 35, so as to form a return bend at the fifth wiring opening 35, and prevent external water from flowing through the fifth wiring opening 35 along the press line into the box.

[0053] Preferably, if Figure 1 and Figure 2 As shown, a limiting plate 421 is further provided at the slot opening of the first wiring slot 41 and / or the second wiring slot 42 of the present invention, and the limiting plate 421 can limit the movement of the wiring harness toward the slot opening.

[0054] The number of the limiting plates 421 can be flexibly set according to needs, as long as they can restrain and fix the wire harness to prevent the wire harness from escaping from the slot.

[0055] In practical applications, those skilled in the art can also flexibly set the limiting plate 421 to other limiting structures such as a clamp, which is not specifically limited in this case.

[0056] Preferably, if Figures 3 and 4 As shown, the outer side of the vertical plate 1 of the present invention is further provided with a first water retaining structure and a second water retaining structure. The first water retaining structure is provided on the upper edge of the second wiring opening 32 , and the second water retaining structure is provided on the upper edge of the fifth wiring opening 35 .

[0057] Exemplarily, the first water retaining structure 321 and the second water retaining structure 351 of the utility model are both configured as water retaining strips, which can block and divert the water flow above the second wiring opening 32 and the fifth wiring opening 35 on the outside of the vertical plate 1, so as to guide the water flow to the two sides of the second wiring opening 32 and the fifth wiring opening 35, thereby preventing the water flow from entering the box through the second wiring opening 32 and the fifth wiring opening 35, and further improving the waterproof performance of the box.

[0058] Preferably, if Figure 1 and Figure 2 As shown, the first wiring channel and the third wiring channel of the present invention are spaced apart, and the second wiring channel is located between the first wiring channel and the third wiring channel.

[0059] By separating the power line and the press line and maintaining a certain distance between them, the electromagnetic interference between the two can be minimized to ensure stable operation of the circuit.

[0060] Preferably, if Figure 1 and Figure 2 As shown, the first wiring channel and / or the second wiring channel and / or the third wiring channel of the present invention are further provided with a magnetic ring installation groove 11. This arrangement facilitates the installation and fixation of the magnetic ring to reduce the interference of electromagnetic signals and ensure the stability and reliability of the circuit.
