DETAILED DESCRIPTION

[0040] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0041] In this disclosure, unless otherwise stated, directional words such as "up" and "down" are generally defined by the upper and lower positions of the electric control box housing in normal use. For example, "up" and "down" can be Figure 1 The terms "up" and "down" in the vertical direction (i.e., the second direction) of the drawings are used solely to facilitate description and simplify the present disclosure. They do not indicate or imply that the devices or components referred to must have a specific orientation, structure, or operation. Therefore, they should not be construed as limitations on the present disclosure. "Inside" and "outside" refer to the inside and outside of the corresponding component outlines. Furthermore, the terms "first," "second," etc., are used to distinguish one element from another and do not convey sequential or significant meanings.

[0042] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0043] like Figures 1 to 8According to the first aspect of the present disclosure, there is provided an electric control box housing 100, comprising a box cover 10, a box body 20 and a rotating shaft 30. A accommodating cavity 21 suitable for accommodating an electric control assembly is provided in the box body 20, and an opening 22 communicating with the accommodating cavity 21 is provided on the box body 20. A first curl 41 is provided on the box body 20, and a second curl 42 is provided on the box cover 10. The rotating shaft 30 passes through the first curl 41 and the second curl 42, and the rotating shaft 30 is configured to be rotatable relative to at least one of the first curl 41 and the second curl 42, so that the box cover 10 can rotate around the rotating shaft 30 to a closed position closing the opening 22 or an open position opening the opening 22, that is, the box cover 10 can rotate around the rotating shaft 30 to a closed position closing the opening 22, or, the box cover 10 can rotate around the rotating shaft 30 to an open position opening the opening 22.

[0044] Through the above technical solution, since the box body 20 is provided with a first coil 41, the box cover 10 is provided with a second coil 42, the rotating shaft 30 is provided through the first coil 41 and the second coil 42, and the rotating shaft 30 is configured to be rotatable relative to at least one of the first coil 41 and the second coil 42, the box cover 10 can be rotated around the rotating shaft 30 to a closed position or an open position. When the electric control assembly needs to be wired or repaired, the box cover 10 can be rotated around the rotating shaft 30 to the open position, so that the opening 22 is opened, so that the staff can wire or repair the electric control assembly in the accommodating chamber 21 through the opening 22. After the wiring or repair is completed, the box cover 10 can be rotated around the rotating shaft 30 to the closed position to close the opening 22, so that the opening 22 is closed, so that the electric control assembly in the accommodating chamber 21 can be well protected.

[0045] Since opening the opening 22 does not require completely removing the box cover 10 from the box body 20, and closing the opening 22 does not require completely reinstalling the box cover 10 on the box body 20, it is helpful to simplify the steps of wiring or repairing the electronic control assembly, thereby helping to improve the efficiency of wiring or repairing the electronic control assembly.

[0046] Moreover, since air conditioners are usually installed at high places, the box cover 10 does not need to be completely removed from the box body 20, and the staff does not need to repeatedly climb up and down to pick up the box cover 10, which is conducive to further improving the staff's efficiency in wiring or repairing the electric control assembly.

[0047] Optionally, the relative rotation between the rotating shaft 30 and the first coil 41 and / or the second coil 42 is a relative rotation with damping, so that the box cover 10 can be maintained at a plurality of open positions with different openings. By arranging the rotating shaft 30 and the first coil 41 to rotate relative to each other with damping, or arranging the rotating shaft 30 and the second coil 42 to rotate relative to each other with damping, or arranging the rotating shaft 30 and the first coil 41 and the second coil 42 to rotate relative to each other with damping, the box cover 10 can be rotated to a suitable opening by a staff member and maintained at that opening, thereby preventing the box cover 10 from swinging on its own and hindering the staff member's operation.

[0048] In the present disclosure, the rotating shaft 30 can be enabled to have damped relative rotation with the first roll 41 in any suitable manner, and the present disclosure does not limit this. As an embodiment, a first damping member, such as a damping sleeve, can be provided between the rotating shaft 30 and the inner wall of the first roll 41. Through the action of the first damping member, the relative rotation with damping between the rotating shaft 30 and the first roll 41 is achieved.

[0049] As another embodiment of the present disclosure, the outer circumferential wall of the rotating shaft 30 may be slightly interference fit with the inner circumferential wall of the first coil 41 to achieve damped relative rotation between the rotating shaft 30 and the first coil 41 .

[0050] In the present disclosure, the rotating shaft 30 can also be enabled to have damped relative rotation with the second roll 42 in any suitable manner. The present disclosure does not limit this. As an embodiment, a second damping member, such as a damping sleeve, can be provided between the rotating shaft 30 and the inner wall of the second roll 42. Through the action of the second damping member, the rotating shaft 30 and the second roll 42 can achieve damped relative rotation.

[0051] As another embodiment of the present disclosure, the outer circumferential wall of the rotating shaft 30 may be slightly interference fit with the inner circumferential wall of the second coil 42 to achieve damped relative rotation between the rotating shaft 30 and the second coil 42 .

[0052] In the present disclosure, the number and position relationship of the first coil 41 and the second coil 42 can be reasonably set according to actual conditions, and the present disclosure does not limit this. As an embodiment, Figure 2 As shown, the number of the second curls 42 can be two, and the two second curls 42 are respectively disposed at opposite ends of the first curl 41. The two second curls 42 are respectively disposed at opposite ends of the axial direction of the first curl 41. On the one hand, this helps to evenly apply force to the shaft 30 during the rotation of the box cover 10, thereby facilitating the rotation of the box cover 10. On the other hand, it helps to increase the area of one side of the box cover 10 covered by the first curl 41 and the second curl 42, thereby improving the sealing between the box cover 10 and the box body 20 in the closed position.

[0053] In addition, the electrical control box housing 100 may also include a limiting structure, which is used to limit the axial position of the rotating shaft 30, that is, to limit the axial movement of the rotating shaft 30 relative to the first coil 41 and the second coil 42, thereby preventing the rotating shaft 30 from falling out of the first coil 41 and the second coil 42 due to axial movement.

[0054] The present disclosure does not limit the structure of the limiting structure. As an implementation method, Figure 2 、 Figure 4 、 Figure 6 and Figure 8 As shown, the number of the second rolls 42 can be two, and the two second rolls 42 are respectively arranged at the opposite ends of the first roll 41. The rotating shaft 30 can include a main shaft section 31 and two bent shaft sections 32, and the two bent shaft sections 32 are respectively arranged at the axial ends of the main shaft section 31, wherein the main shaft section 31 passes through the first roll 41 and the two second rolls 42, and the two bent shaft sections 32 are constructed as a limiting structure, which is used to press against and limit the corresponding second roll 42 at one end away from the first roll 41.

[0055] Since the two bent shaft segments can respectively abut the ends of the two second coils 42 away from the first coil 41 , the rotating shaft 30 can be prevented from axial movement, thereby preventing the rotating shaft 30 from falling out of the first coil 41 and the second coil 42 .

[0056] Here, optionally, the material of the rotating shaft 30 can be a plastically deformable metal. When the box cover 10 and the box body 20 are assembled, the rotating shaft 30 extending in the same direction from head to tail can be passed through one of the second curls 42, the first curl 41 and the other second curl 42 in sequence, and then the two ends of the rotating shaft 30 can be bent so that the two ends of the rotating shaft 30 form a bent shaft section 32, and the middle part of the rotating shaft 30 forms a main shaft section 31.

[0057] As other embodiments of the present disclosure, two stop blocks can be formed on the box body 20, and the two stop blocks are respectively located at both ends of the rotating shaft 30, so as to prevent the rotating shaft 30 from sliding out of the first roll 41 and the second roll 42 along the axial direction, thereby realizing axial limitation of the part of the rotating shaft 30 located outside the first roll 41 and the second roll 42.

[0058] In order to reduce the interference of the box cover 10 on the operation of the staff, as an embodiment, Figure 2 and Figure 3As shown, the box body 20 includes a first side wall 23 and a second side wall 24 adjacent to the first side wall 23. The opening 22 is located on the first side wall 23, and the first bead 41 is provided at the connection between the first side wall 23 and the second side wall 24. Since the first bead 41 is provided at the connection between the first side wall 23 and the second side wall 24, the box cover 10 can be located at the edge of the first side wall 23 when in the open position, thereby helping to reduce the obstruction of the box cover 10 to the operator's operation.

[0059] In order to further reduce the obstruction of the box cover 10 to the operation of the staff, as an embodiment, Figure 2 and Figure 3 As shown, the first curl 41 is located at one end of the first side wall 23 in the first direction (e.g., horizontal direction), the axial direction of the first curl 41 is parallel to the second direction (e.g., vertical direction), and the second direction intersects the first direction. Since the first curl 41 is located at one end of the first side wall 23 in the first direction and the axial direction of the first curl 41 is parallel to the second direction, the lid 10 can be rotated to a larger opening, for example, the lid 10 can be rotated to a position closer to the second side wall 24, thereby further reducing the obstruction of the lid 10 to the operator's operation.

[0060] Here, optionally, the first direction may be a horizontal direction, and the second direction may be a vertical direction.

[0061] Alternatively, as Figure 5 and Figure 7 As shown, the first roll 41 is provided with a first gap 411 extending along the axial direction of the first roll 41 (which may be axially extending through both axial ends of the first roll 41), and the width of the first gap 411 is smaller than the diameter of the rotating shaft 30, and / or, the second roll 42 is provided with a second gap 421 extending along the axial direction of the second roll 42 (which may be axially extending through both axial ends of the second roll 42), and the width of the second gap 421 is smaller than the diameter of the rotating shaft 30.

[0062] By setting the first gap 411 with a width smaller than the diameter of the rotating shaft 30, the material of the first roll 41 can be saved while ensuring that the rotating shaft 30 does not fall out of the first roll 41, thereby helping to reduce the cost of the electric control box housing 100 and helping to reduce the weight of the electric control box housing 100.

[0063] Similarly, by setting a second gap 421 with a width smaller than the diameter of the rotating shaft 30, the material of the second coil 42 can be saved while ensuring that the rotating shaft 30 does not fall out of the second coil 42, thereby helping to reduce the cost of the electric control box housing 100 and helping to reduce the weight of the electric control box housing 100.

[0064] The present disclosure does not limit the connection method between the first coil 41 and the box body 20. As an embodiment, the first coil 41 can be integrally formed with the box body 20, thereby facilitating a good connection strength between the first coil 41 and the box body 20. In particular, when the box body 20 and the first coil 41 are made of metal, the first coil 41 can be formed by sheet metal processing.

[0065] As another embodiment of the present disclosure, the first curl 41 may be connected to the box body 20 via fasteners.

[0066] The present disclosure does not limit the connection method between the second curl 42 and the box body 20. As an embodiment, the second curl 42 can also be integrally formed with the box body 20, thereby facilitating a good connection strength between the second curl 42 and the box cover 10. In particular, when the box cover 10 and the second curl 42 are made of metal, the second curl 42 can be formed by sheet metal processing.

[0067] As another embodiment of the present disclosure, the second curl 42 may be connected to the box body 20 via fasteners.

[0068] In order to open or close the box cover 10 and avoid the box cover 10 in the closed position from being accidentally opened, as an embodiment, Figure 3 As shown, the box body 20 may be provided with a first connecting portion 71, which is located on a side of the box body 20 opposite the first curl 41. The box cover 10 may be provided with a second connecting portion 72, which is detachably connected to the first connecting portion 71, thereby enabling the box cover 10 to be opened and closed. In addition, after completing wiring or maintenance of the electronic control assembly, the first connecting portion 71 and the second connecting portion 72 may be detachably connected, thereby preventing the box cover 10 from being accidentally opened when in the closed position, thereby facilitating the safety of the electronic control assembly and the user.

[0069] The present disclosure does not limit the structure of the first connecting portion 71 and the second connecting portion 72, as long as the first connecting portion 71 and the second connecting portion 72 can be detachably connected. As an embodiment, Figure 3 As shown, the electric control box housing 100 further includes a threaded fastener, the first connection portion 71 is configured as a threaded hole, the second connection portion 72 is a through hole, the threaded fastener is passed through the through hole and is threadedly connected to the threaded hole.

[0070] As another embodiment of the present disclosure, the first connecting portion 71 may be a slot, and the second connecting portion 72 may be a block. The first block may be inserted into the slot and slightly deformed.

[0071] According to a second aspect of the present disclosure, an electric control box is provided, comprising an electric control assembly and the above-mentioned electric control box housing 100, wherein the electric control assembly is accommodated in the accommodation cavity 21. The electric control assembly may include but is not limited to a power module, a control module, an input / output interface, and the like.

[0072] According to a third aspect of the present disclosure, an air-conditioning device is provided, comprising the above-mentioned electric control box.

[0073] The present disclosure does not limit the type of air-conditioning equipment. For example, the air-conditioning equipment may be a ducted air conditioner.
