[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0047] The present invention proposes an electric control box 100 for use with equipment such as an air conditioner. The air conditioner includes an outdoor air conditioner unit and an indoor air conditioner unit. A flexible connection assembly connects the indoor air conditioner unit and the outdoor air conditioner unit, respectively. The air conditioner can be a split-type air conditioner that is easy for users to install individually. The air conditioner uses a refrigerant pipe to connect the indoor heat exchanger of the indoor air conditioner unit and the outdoor heat exchanger of the outdoor air conditioner unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment themselves, they only need to fix the indoor air conditioner unit and the outdoor air conditioner unit separately, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be an ordinary split-type air conditioner or an integrated air conditioner.

[0048] See also Figures 1 to 5 In one embodiment of the present invention, the electric control box 100 includes:

[0049] Shell 1;

[0050] A circuit board 2 is disposed in the housing 1; and

[0051] The wiring bracket 3 is disposed in the housing 1 and spaced apart from the circuit board 2 to form a first wiring space 31 . The first wiring space 31 is used for arranging the conductive wire harness 4 in the power control box 100 .

[0052] Specifically, the housing 1 includes a housing space 11 for accommodating a circuit board 2, a conductive wiring harness 4, and several power devices. The electrical control box 100 often includes multiple conductive wiring harnesses 4, each used to control different power devices within the box, thereby controlling the air conditioner and achieving its various functions. Consequently, the housing space 11 typically includes numerous conductive wiring harnesses 4, leading to a somewhat chaotic layout of the wiring within the box 100. This not only affects the air conditioner's operating efficiency but also poses potential safety hazards, complicates maintenance, and hinders heat dissipation within the box.

[0053] Therefore, in this solution, a circuit board 2 is provided to reduce the number of conductive wire bundles 4 within the electrical control box 100. A wiring bracket 3 is also provided to create a first wiring space 31 for the conductive wire bundles 4. This standardizes the layout of the conductive wire bundles 4 within the electrical control box 100 and reduces wire clutter. Furthermore, the wiring bracket 3 is spaced apart from the circuit board 2, thereby separating the first wiring space 31 from the circuit board 2 and improving electrical safety within the electrical control box 100.

[0054] The first wiring space 31 can be formed solely by the wiring bracket 3, in which case a channel for placing the conductive wire bundle 4 is defined within the wiring bracket 3. The first wiring space 31 can also be formed by the wiring bracket 3 and the inner wall of the housing 1. The electrical control box 100 can be provided with only one wiring bracket 3, with a portion of the conductive wire bundle 4 arranged within the first wiring space 31. Alternatively, multiple wiring brackets 3 can be provided to form multiple first wiring spaces 31, allowing the conductive wire bundles 4 to be arranged independently of each other, further improving electrical safety within the electrical control box 100.

[0055] The technical solution of this utility model reduces the number of conductive wires 4 within the electrical control box 100 by arranging a circuit board 2 and a wiring bracket 3 within the housing 1. This creates a first wiring space 31 for the conductive wires 4, thereby standardizing the layout of the conductive wires 4 within the electrical control box 100 and reducing wire clutter. Furthermore, the wiring bracket 3 is spaced apart from the circuit board 2, thereby separating the first wiring space 31 from the circuit board 2, thereby improving electrical safety within the electrical control box 100.

[0056] In an embodiment of the present invention, the first wiring space 31 is configured as a first wiring groove 311 provided on the wiring bracket 3, and the first wiring groove 311 is provided with at least one first wire-holding structure 32, and the first wire-holding structure 32 is used to limit the conductive wire bundle 4. Specifically, the wiring bracket 3 is provided with a first wiring groove 311, thereby limiting the extension direction and arrangement of the conductive wire bundle 4, thereby limiting the conductive wire bundle 4. The first wiring groove 311 defines the first wiring space 31 of the conductive wire bundle 4, and in order to reduce the possibility of the conductive wire bundle 4 escaping from the first wiring groove 311, at least one first wire-holding structure 32 is provided in the first wiring groove 311, and the first wire-holding structure 32 is used to prevent the conductive wire bundle 4 from escaping from the first wiring groove 311. Multiple first wire-holding structures 32 are provided at least near the end of the first wiring groove 311.

[0057] The wiring bracket 3 may be provided with only one first wiring groove 311, or multiple first wiring grooves 311. When the wiring bracket 3 is provided with multiple first wiring grooves 311, the multiple conductive wire bundles 4 are located in different first wiring grooves 311, allowing the conductive wire bundles 4 to be independently arranged, further improving electrical safety within the electrical control box 100. In other embodiments, the wiring bracket 3 may not be provided with a first wiring groove 311, and may only be provided with multiple spaced-apart first wire-holding structures 32. The multiple first wire-holding structures 32 collectively limit the path of the conductive wire bundles 4.

[0058] See also Figure 1 and Figure 2 In an embodiment of the present invention, the first wire-holding structure 32 includes two spaced-apart first stoppers 321 that extend toward each other to prevent the conductive wire bundle 4 from escaping. Specifically, the two first stoppers 321 are located on opposite sides of the first wiring trough 311 and extend toward each other, thereby partially reducing the opening of the first wiring trough 311 and preventing the conductive wire bundle 4 from escaping. To facilitate installation of the conductive wire bundle 4, the two first stoppers 321 extend toward each other and then toward each other, thereby widening the opening between the two conductive wire bundles 4 and facilitating installation.

[0059] In another embodiment of the present invention, the first wire-holding structure 32 includes a second stopper 322, one end of which is connected to one side of the first wiring groove 311, and the other end of which extends toward the other side of the first wiring groove 311 and is spaced apart from the other side of the first wiring groove 311. Specifically, one end of the second stopper 322 is connected to one side of the first wiring groove 311, and the other end of which extends toward the other side of the first wiring groove 311, and the other end of the second stopper 322 is spaced apart from the other side of the first wiring groove 311, thereby changing the partial opening direction of the first wiring groove 311, so that the second stopper 322 can prevent the conductive wire bundle 4 from escaping. In order to further reduce the possibility of the conductive harness 4 escaping from the first wiring groove 311, the distance between the other end of the second limiting member 322 and the other side of the first wiring groove 311 is smaller than the width of the first wiring groove 311, and in order to facilitate the installation of the conductive harness 4, the other end of the second limiting member 322 extends toward the other side of the first wiring groove 311 and then extends again in the direction away from the other side of the first wiring groove 311, thereby facilitating the installation of the conductive harness 4.

[0060] See also Figure 3 and Figure 4 In an embodiment of the present invention, the first wiring trough 311 includes a main trough section 312 and at least one sub-trough section 313 connected to the main trough section 312. Both the main trough section 312 and the sub-trough section 313 are provided with at least one first wire-holding structure 32. Specifically, when multiple conductive wire bundles 4 have similar functions and / or connect similar power devices and / or have equal voltages, the multiple conductive wire bundles 4 can first pass through the main trough section 312 together and then pass through the multiple sub-trough sections 313 separately. This not only facilitates the installation of the conductive wire bundles 4, but also reduces the overall size of the wiring bracket 3, contributing to the miniaturization of the electrical control box 100. Both the main trough section 312 and the sub-trough section 313 are provided with at least one first wire-holding structure 32, which controls the routing of the conductive wire bundles 4 within the first wiring trough 311.

[0061] To better accommodate the conductive harness 4, the first wiring trough 311 is curved in this embodiment of the present invention, and its corners are chamfered. Because the conductive harness 4 is generally flexible and thus has no folding angles during bending, the chamfered corners of the first wiring trough 311 ensure a more consistent fit. Furthermore, the curved design of the first wiring trough 311 allows for as many conductive harnesses 4 as possible to fit within a limited space.

[0062] In order to further improve the safety of electricity use in the electric control box 100, in the embodiment of the present utility model, please refer to Figure 5The wiring bracket 3 is spaced apart from the housing 1, and the distance between the wiring bracket 3 and the housing 1 is greater than or equal to 5 mm. According to safety distance regulations for the electric control box 100, the distance between the conductive wire harness 4 and the external housing 1 is greater than or equal to 5 mm. Therefore, by setting the distance between the wiring bracket 3 and the housing 1 to be greater than or equal to 5 mm, the distance between the conductive wire harness 4 and the external housing 1 is greater than or equal to 5 mm, thereby further improving the electrical safety of the electric control box 100. The specific distance between the wiring bracket 3 and the housing 1 can be 5 mm, 6 mm, 7 mm, etc.

[0063] See also Figures 1 to 4 In an embodiment of the present invention, the conductive wiring harness 4 includes a high-voltage wiring harness 41 and a low-voltage wiring harness 42. There is also a second wiring space 12 in the shell 1. The high-voltage wiring harness 41 is arranged in the first wiring space 31, and the low-voltage wiring harness 42 is arranged in the second wiring space 12. Specifically, the conductive wiring harness 4 is roughly divided into a high-voltage wiring harness 41 and a low-voltage wiring harness 42. The high-voltage wiring harness 41 is mainly used for the electrical connection of high-voltage bodies, which generally include drive motors, power supply systems, and control of high-power loads; the low-voltage wiring harness 42 is mainly used for the electrical connection of low-voltage bodies and signal transmission: low-voltage bodies generally include control circuits, safety protection, and user interfaces. The voltage difference between the high-voltage wiring harness 41 and the low-voltage wiring harness 42 is large, so a second wiring space 12 separated from the first wiring space 31 is set. The high-voltage wiring harness 41 is arranged in the first wiring space 31, and the low-voltage wiring harness 42 is arranged in the second wiring space 12, which helps to achieve the separation of high and low voltage, thereby further improving the power safety of the distribution box.

[0064] Furthermore, a gap is provided between the circuit board 2 and the inner wall of the housing 1 to form a second wiring space 12. Specifically, the gap between the circuit board 2 and the inner wall of the housing 1 forms the second wiring space 12, and the circuit board 2 and the housing 1 together serve as the walls of the second wiring trough, eliminating the need for an additional wiring bracket 3, thereby facilitating the miniaturization of the electrical control box 100. Of course, in other embodiments, another wiring bracket may be provided, forming the second wiring space 12 spaced apart from the first wiring space 31, or providing the first wiring space 31 and the second wiring space 12 spaced apart from each other.

[0065] To further reduce the possibility of the weak-wire harness 42 escaping the second wiring space 12, in this embodiment, a second wire-locking structure 121 is provided in the second wiring space 12. The second wire-locking structure 121 is used to prevent the weak-wire harness 42 from escaping the first wiring space 31. Multiple second wire-locking structures 121 are provided at least at the end of the first wiring space 31.

[0066] See also Figure 1 and Figure 2In an embodiment of the present invention, the second wire-holding structure 121 includes two spaced-apart third stoppers 122 that extend toward each other to prevent the weak-wire harness 42 from escaping. Specifically, two first stoppers 321 are disposed on opposite sides of the first wiring trough 311 and extend toward each other, thereby partially reducing the opening of the first wiring trough 311 and preventing the conductive harness 4 from escaping. To facilitate installation of the conductive harness 4, the two first stoppers 321 extend toward each other and then toward each other, thereby widening the opening between the two conductive harnesses 4 and facilitating installation.

[0067] In another embodiment of the present invention, the second wire clamping structure 121 includes a fourth limiter, one end of which is connected to one side of the second wiring space 12, and the other end extends toward the other side of the second wiring space 12 and is spaced apart from the other side of the second wiring space 12.

[0068] To facilitate the installation of the wiring bracket 3, in the embodiment of the present invention, the wiring bracket 3 includes a main body 33 and a mounting portion 34. The main body 33 forms a first wiring space 31. The mounting portion 34 is snapped onto the housing 1, and the main body 33 is spaced apart from the circuit board 2. Specifically, the main body 33 of the wiring bracket 3 is used to form the first wiring space 31, that is, the first wiring groove 311 is provided on the main body 33. The mounting portion 34 is configured as a mounting arm, so that the main body 33 is suspended on the circuit board 2 by snapping the mounting portion 34 onto the housing 1. The mounting portion 34 can be installed on the same side wall of the housing 1 as the circuit board 2. In this case, the first mounting portion 34 is installed on the outer edge of the circuit board 2. The mounting portion 34 and the circuit board 2 can also be separately provided on two opposite side walls of the housing 1.

[0069] See also Figure 1 、 Figure 3 、 Figure 7 and Figure 8 In this embodiment, the housing 1 is provided with a wiring opening 13 for the conductive wire harness 4 to pass through, and the wiring opening 13 is provided with a wire-collecting portion 131. The wire-collecting portion 131 is used to limit the position of the conductive wire harness 4. Specifically, the conductive wire harness 4 passes through the wiring opening 13 and out of the electrical control board to electrically connect to the electrical components within the air conditioner. Therefore, the wiring opening 13 is often provided with multiple wiring openings. In order to further collect the conductive wire harness 4, the wiring opening 13 is provided with a wire-collecting portion 131. The wire-collecting portion 131 is used to limit the position of the conductive wire harness 4.

[0070] See also Figure 5 and Figure 6In order to ensure the electrical safety and use safety of the electric control box, the shell 1 includes an insulating shell 17 and a fireproof shell 16 wrapped around the outer periphery of the insulating shell 17. The insulating shell 17 is usually made of insulating materials such as plastic, and the fireproof shell 16 is usually made of fireproof materials such as metal.

[0071] See also Figure 1 、 Figure 3 、 Figures 5 to 8 In this embodiment of the present invention, the housing 1 is further provided with a grounding member 5, which extends out of the housing 1 and is connected to a grounding wire 51 to ground the electric control box 100;

[0072] The housing 1 is provided with an outwardly protruding anti-rotation protrusion 14 . The anti-rotation protrusion 14 is provided on at least one side of the grounding member 5 to limit the grounding wire 51 .

[0073] Specifically, a portion of the grounding member 5 extends from the distribution box, and the portion of the grounding member extending from the housing 1 is connected to the grounding wire 51, thereby grounding the electrical control box 100 and ensuring electrical safety of the electrical control box 100. Furthermore, at least one side of the grounding member 5 is provided with an outwardly protruding anti-rotation protrusion 14. The anti-rotation protrusion 14 is mounted on the housing 1 and located on at least one side of the grounding member 5. The anti-rotation protrusion 14 abuts against one side of the grounding wire 51, thereby limiting the rotation of the grounding wire 51 and reducing the possibility of the grounding member 5 rotating on its own, which could drive the grounding member 5 to rotate and cause the grounding member 5 to separate from the housing 1, or the grounding wire 51 to separate from the grounding member 5, thereby ensuring electrical safety of the electrical control box 100.

[0074] In the embodiment of the present invention, the housing 1 is provided with a thickened portion 15, to which the grounding member 5 and the anti-rotation protrusion 14 are both mounted, and the thickness of the thickened portion 15 is greater than the thickness of the periphery of the thickened portion 15. Specifically, the thickness of the housing 1 is generally thin, especially the thickness of the fireproof shell 16, which makes it difficult to ensure the installation stability of the grounding member 5 and the housing 1. For example, when the grounding member 5 and the housing 1 are connected by threads, the housing 1 is thin and prone to thread slippage. Therefore, the housing 1 is provided with a thickened portion 15, and the thickness of the thickened portion 15 is greater than the thickness of the periphery of the thickened portion 15, that is, the housing 1 is locally thickened. The grounding member 5 and the anti-rotation protrusion 14 are both mounted on the thickened portion 15, which helps to ensure the installation stability of the grounding member 5 and the housing 1.

[0075] Therefore, in one embodiment, the housing 1 includes a fireproof shell 16 , and the edge of the fireproof shell 16 is provided with a flange that fits the outer surface of the fireproof shell 16 to form a thickened portion 15 , thereby facilitating the processing of the fireproof shell 16 .

[0076] Furthermore, a thinned portion 151 is partially provided on the thickened portion 15, and the anti-rotation protrusion 14 is mounted on the thinned portion 151. The thickness of the thinned portion 151 is less than the thickness of the remaining portion of the thickened portion 15. Because the anti-rotation protrusion 14 protrudes from the exterior of the housing 1, to facilitate the processing of the anti-rotation protrusion 14, the anti-rotation protrusion 14 can be formed by partially stamping the thickened portion 15. However, since the thickened portion 15 is relatively thick, processing is difficult. Therefore, the thinned portion 151 is partially provided on the thickened portion 15. The thickness of the thinned portion 151 is less than the thickness of the remaining portion of the thickened portion 15. This allows the local thinning of the thickened portion 15 and the mounting of the anti-rotation protrusion 14 on the thinned portion 151 to facilitate the processing of the anti-rotation protrusion 14.

[0077] In other embodiments, the anti-rotation protrusion 14 can be directly bonded, clamped, or screwed to the housing 1 , and in this case, there is no need to provide an additional thinning portion 151 . The thinning portion 151 can be configured as a thinning groove provided in a portion of the thickened portion 15 .

[0078] Furthermore, the thickness of the housing 1 is less than or equal to 0.6 mm;

[0079] The thickness of the thickened portion 15 is greater than or equal to 0.6 mm and less than or equal to 1.2 mm;

[0080] The thickness of the thinned portion 151 is greater than or equal to 0.6 mm and less than or equal to 0.8 mm.

[0081] Specifically, if the thickness of the housing 1 is less than 0.6 mm, it is not only difficult to process the housing 1, but also difficult to ensure the installation strength of the housing 1. Specifically, the thickness of the housing 1 can be 0.6 mm, 0.7 mm, 0.8 mm, etc. The thickness of the thickened portion 15 is greater than the thickness of the periphery of the thickened portion 15. Therefore, the thickness of the thickened portion 15 must be greater than or equal to 0.6 mm. If the thickness of the thickened portion 15 is greater than 1.2 mm, the thickness of the thickened portion 15 is too thick, which is not conducive to the flatness of the surface of the electric control box 100.
