[0058] The embodiments of the present invention are described in detail below, and examples of the embodiments 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.

[0059] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0060] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0061] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0062] In the related art, in order to fix the wiring harness in the electric control box, the wiring harness is usually pressed and fixed to the box body by the cooperation of wire buckles and screws. However, when implementing this wiring harness fixing method, the staff needs to complete the installation of the wire buckle and the screw separately, which increases the assembly process of the electric control box. Therefore, it will not only increase the complexity of the assembly of the electric control box and increase the assembly time, but also easily increase the risk of assembly errors, resulting in reduced assembly efficiency and assembly quality of the electric control box. In addition, this wiring harness fixing method is difficult to match the assembly of the automated production line, resulting in a low degree of automation. The use of wire buckles and screws will also increase additional costs, making the production cost of the electric control box higher.

[0063] Reference Figure 1 , Figure 2 and Figure 3 As shown, an electric control box 1000 of an embodiment of the utility model may include: a box body 100, a wiring harness and a cover body 400. The box body 100 may be a hollow structure, and an installation space may be provided inside the box body 100 for installing electric control components such as an electric control board. The box body 100 may be made of plastic injection molding or sheet metal, and those skilled in the art may choose according to actual conditions, and this embodiment does not limit this.

[0064] In the embodiment of the utility model, the wiring harness may include wires such as air conditioner indoor unit connection wire and air conditioner outdoor unit connection wire. It should be noted that the number of wires in the wiring harness may be one, two or more, and this embodiment does not limit this.

[0065] Reference Figure 3 , Figure 4 and Figure 5As shown, in an embodiment of the utility model, the box body 100 may be provided with a fixing groove, and the peripheral wall of the wiring harness may be fixedly provided with a connecting portion that is snapped into the fixing groove. It is understandable that the fixing groove may be a semi-open mounting structure, and the fixing groove may match the shape and size of the connecting portion. In this embodiment, the connecting portion may be extended from the peripheral wall of the wiring harness in a certain direction to form a convex block, or may be extended along the circumferential direction of the peripheral wall of the wiring harness to be sleeved on the wiring harness. When the connecting portion is located in the fixing groove, the groove wall of the fixing groove may be tightly fitted with the peripheral wall of the connecting portion, so that the connecting portion is snapped into the fixing groove, thereby limiting the wiring harness and achieving the fixation of the wiring harness.

[0066] Based on this, when assembling the wiring harness, the worker can directly place the connecting part into the fixing groove to complete the assembly of the wiring harness. At this time, the groove wall of the fixing groove can play a guiding role, which not only allows the worker to easily align the connecting part with the fixing groove, but also enables the connecting part to quickly enter the fixing groove. It can be understood that this embodiment fixes the wiring harness by adopting a method of clamping the connecting part with the fixing groove, replacing the technical solution of the prior art that the wiring harness is pressed and fixed to the box body 100 by the cooperation of the wire buckle and the screw. When assembling the wiring harness, the assembly process of the wire buckle and the screw is eliminated, which not only reduces the complexity of the wiring harness assembly, facilitates the workers' operation, and brings a better assembly experience to the workers, but also shortens the assembly time of the wiring harness, thereby improving the efficiency of the wiring harness assembly.

[0067] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the cover body 400 can be covered on the box body 100. Specifically, the cover body 400 and the box body 100 can be connected by a threaded fitting, or by a buckle connection, or by other detachable connection methods. The cover body 400 can press the connection part into the fixing groove. Specifically, when the cover body 400 is connected to the box body 100, the cover body 400 can abut against the connection part, thereby limiting the connection part and fixing it in the fixing groove. Through the groove wall of the fixing groove and the limit of the connection part by the cover body 400, the connection part can be stably maintained in the fixing groove, reducing the possibility of the connection part being loose, thereby improving the stability of the wiring harness.

[0068] Reference Figure 1 , Figure 2 and Figure 3As shown, in the embodiment of the utility model, a wire hole for the wire harness to pass through can be formed between the cover body 400 and the box body 100, and the wire hole is connected to the fixing groove. Based on this, when the connecting portion is located in the fixing groove, the wire harness can be passed through the wire hole. In this embodiment, the wire hole can be formed in the box body 100, can also be formed in the cover body 400, and can also be formed in the gap between the two. It is understood that the shape and size of the wire hole can match the wire harness, so that the wire harness can pass through the wire hole to the outside of the electric control box 1000. It is understood that in this embodiment, two fixing grooves can be provided. Specifically, in one example, the box body 100 can be provided with a first fixing groove 110 and a second fixing groove 120, a first wire hole 111 can be formed between the first fixing groove 110 and the cover body 400, and a second wire hole 121 can be formed between the second fixing groove 120 and the cover body 400.

[0069] The utility model provides a fixing groove on the box body 100 and a connecting part on the peripheral wall of the wiring harness, and enables the connecting part to be snapped into the fixing groove, so that workers can easily and accurately place the connecting part into the fixing groove, and the wiring harness can be quickly connected to the box body 100, which not only shortens the assembly time and improves the assembly efficiency of the wiring harness, but also reduces the complexity of assembling the wiring harness, reduces the difficulty of operation for workers, and thus reduces the possibility of assembly errors, thereby improving the assembly quality of the electric control box 1000; and then a cover body 400 is provided on the box body 100, and a wire hole for the wiring harness to pass through is formed between the cover body 400 and the box body 100, and the cover body 400 can press the connecting part into the fixing groove, so that the connecting part can be firmly fixed in the fixing groove, and the possibility of the connecting part loosening is reduced. The position of the connecting part is limited by the cover body 400, and the stability of the wiring harness is increased, thereby improving the integrity and reliability of the electric control box 1000, so that the assembly of the electric control box 1000 can be more easily matched with the assembly of the automated production line, and the degree of automated generation is improved, and it is suitable for the indoor unit of the air conditioner.

[0070] Reference Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the connecting portion can be sleeved on the wire harness. Specifically, the connecting portion can be extended along the circumferential direction of the outer peripheral wall of the wire harness, so as to form a connecting structure that matches the shape and size of the fixing groove. Based on this, when the connecting portion is placed in the fixing groove, the connecting portion can fit with the inner wall of the fixing groove. Specifically, each end face of the connecting portion can fit with the corresponding inner wall in the fixing groove, so as to limit the connecting portion and make it stably fixed in the fixing groove. At the same time, the force of the fixing groove on the connecting portion can be evenly transmitted to the wire harness, reducing the possibility of stress concentration in the wire harness and improving the reliability and stability of the wire harness. It should be noted that the connecting portion and the wire harness can be integrally formed.

[0071] In the embodiment of the utility model, the outer peripheral wall of the connecting portion may be provided with one of the positioning ribs and the positioning grooves, and the inner wall of the fixing groove may be provided with the other of the positioning ribs and the positioning grooves. Specifically, referring to Figure 6 , Figure 7 and Figure 8 As shown, the outer peripheral wall of the connecting portion may be provided with positioning ribs, and the inner wall of the fixing groove may be provided with positioning grooves corresponding to the positioning ribs; or, referring to Fig. 9 , Fig.10 and Fig.11 As shown, the outer peripheral wall of the connection part may be provided with a positioning groove, and the inner wall of the fixing groove may be provided with a positioning rib corresponding to the positioning groove. It should be noted that in this embodiment, the positioning rib may be extended outward from the end surface of the connection part, or may be extended inward from the inner wall of the fixing groove; the positioning groove may be extended inward from the end surface of the connection part, or may be extended outward from the inner wall of the fixing groove.

[0072] In this embodiment, the positioning rib can be slidably connected to the positioning groove. It is understandable that when a worker assembles the wiring harness, the connection part can be quickly placed in the fixed groove by aligning the positioning rib and the positioning groove. The cooperation between the positioning rib and the positioning groove plays a guiding role, thereby improving the assembly efficiency of the wiring harness. When the wiring harness is located in the fixed groove, the cooperation between the positioning rib and the positioning groove can also limit the connection part, further improving the stability of the connection part.

[0073] Reference Fig.12 , Fig.13 and Fig.14 As shown, in the embodiment of the utility model, along the axial direction of the wire harness, the cross-sectional area of ​​the connection part gradually decreases from the middle part to the two ends. Specifically, the outer peripheral wall of the connection part can be two inclined surfaces arranged symmetrically along the radial direction of the connection part, and the two inclined surfaces can be arranged obliquely along the axial direction of the wire harness, respectively, so as to form a connection part with a large outer diameter in the middle part and a small outer diameter at both ends. Correspondingly, the inner wall surface profile of the fixing groove matches the outer wall surface profile of the connection part. Specifically, along the axial direction of the wire harness, the inner diameter of the fixing groove can gradually decrease from the middle part to the two ends. Based on this, the inner wall of the fixing groove can fit tightly with the outer peripheral wall of the connection part, so as to limit the connection part, thereby achieving the fixation of the wire harness.

[0074] In the embodiment of the utility model, at least two wire harnesses are provided, and at least two wire harnesses are arranged side by side in the fixing groove. The following description is made by taking the case where two wire harnesses are provided as an example. Specifically, the two wire harnesses are respectively the first wire harness 200 and the second wire harness 300. The outer peripheral wall of the first wire harness 200 is sleeved with the first connecting part 210, and the outer peripheral wall of the second wire harness 300 is sleeved with the second connecting part 310. In the present embodiment, the dimension of the fixing groove in its length direction matches the dimension when the first connecting part 210 and the second connecting part 310 are arranged side by side, and therefore, the first connecting part 210 and the second connecting part 310 can be arranged in the fixing groove at the same time.

[0075] Reference Figure 4 and Figure 5 As shown, in one example, the first fixing slot 110 includes a first fixing position 114 and a second fixing position 115, and the first fixing position 114 and the second fixing position 115 are arranged along the length direction of the first fixing slot 110. The first fixing position 114 corresponds to the first connecting portion 210, and the second fixing position 115 corresponds to the second connecting portion 310. A first opening 1141 is provided at the upper end of the first fixing position 114, and a second opening 1151 is provided at the upper end of the second fixing position. The first opening 1141 and the second opening 1151 may be connected or not connected, and this embodiment does not limit this.

[0076] Taking the example that the first opening 1141 and the second opening 1151 are connected to each other, in this embodiment, the first opening 1141 and the second opening 1151 are connected to each other, that is, the first fixing groove 110 is an open structure, and its open mouth faces upward. When assembling the first wire harness 200 and the second wire harness 300, the first connecting portion 210 and the second connecting portion 310 can be firstly pressed against each other, and then the first connecting portion 210 and the second connecting portion 310 are placed together into the first fixing groove 110 from the open mouth of the first fixing groove 110, wherein the first connecting portion 210 is placed in the first fixing position 114, and the second connecting portion 310 is placed in the second fixing position 115.

[0077] Reference Fig.18 As shown, in another example, the first fixing slot 110 includes a first fixing position 114 and a second fixing position 115, and the first fixing position 114 and the second fixing position 115 are arranged along the length direction of the first fixing slot 110. The first fixing position 114 corresponds to the first connecting portion 210, and the second fixing position 115 corresponds to the second connecting portion 310. Fig.19 As shown, the second wire fixing position 115 is provided with a second opening 1151 at one end facing the cover body 400, and the second opening 1151 is connected to the first fixing groove 110. Based on this, it can be understood that the first wire fixing position 114 is located inside the first fixing groove 110, and the second wire fixing position 115 is located outside the first fixing groove 110.

[0078] Reference Fig.17 and Fig. 20 As shown, in this embodiment, when assembling the first wiring harness 200 and the second wiring harness 300, the first connecting portion 210 and the second connecting portion 310 can be slid into the first fixing groove 110 from the second opening 1151 in sequence, so that the first connecting portion 210 slides to the first fixing position 114, and the second connecting portion 310 slides to the second fixing position 115.

[0079] In the embodiment of the utility model, the box body 100 is a semi-open structure, wherein a wire fixing seat 500 is provided at one end of the box body 100 facing the cover body 400, and the wire harness extends from the inside of the box body 100 toward the wire fixing seat 500. Figure 5 , Figure 7 and Fig.13 As shown, the cover 400 and the box body 100 are arranged along the up and down direction of the electric control box 1000. Based on this, the wire fixing seat 500 is arranged at the top of the box body 100, and the fixing groove is arranged at the top of the wire fixing seat 500. Specifically, referring to Figure 5 As shown, the first fixing groove 110 is provided at the edge of the wire fixing seat 500, and the first opening 1141 and the second opening 1151 are provided upward. When assembling the first wire harness 200 and the second wire harness 300, the first connecting portion 210 and the second connecting portion 310 can be respectively placed in the first wire fixing position 114 and the second wire fixing position 115 from top to bottom, and then the cover body 400 is covered on the top of the box body 100, thereby pressing the first connecting portion 210 and the second connecting portion 310.

[0080] In another example, referring to Fig.16 and Fig.18 As shown, the cover body 400 and the box body 100 are arranged along the width direction of the electric control box 1000. Based on this, the wire fixing seat 500 is arranged on the side wall of the box body 100 along the width direction of the electric control box 1000, and the wire fixing seat 500 is connected to the side wall and protrudes toward the cover body 400. Specifically, the wire fixing seat 500 is opened at one end close to the cover body 400, that is, the open mouth of the wire fixing seat 500 is opened at the side wall of the wire fixing seat 500 along the width direction of the electric control box 1000, and the open mouth can allow the wire harness to enter. The first fixing groove 110 is arranged at one end of the wire fixing seat 500 close to the cover body 400. It can be understood that in this embodiment, the second opening 1151 is a part of the open mouth, and the first wire hole 111 is arranged on the cover body 400.

[0081] When assembling the first wiring harness 200 and the second wiring harness 300, the first connecting part 210 and the second connecting part 310 can be placed in the first wire fixing position 114 and the second wire fixing position 115 in sequence from the second opening 1151 along the width direction of the electric control box 1000, and then the cover body 400 is covered on one side of the box body 100, thereby pressing the first connecting part 210 and the second connecting part 310.

[0082] Reference Fig.15 As shown, in the embodiment of the present invention, the structure formed by the cover body 400 covering the box body 100 is a semi-open structure. In order to close the electric control box 1000, in this embodiment, the electric control box 1000 also includes a cover plate 600. Fig.21 As shown, the cover plate 600 covers the open structure, thereby improving the airtightness of the electric control box 1000 and enhancing the protection performance of the electric control box 1000.
