Detailed Implementation

[0020] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0022] The embodiments described in this specification will now be described in detail.

[0023] Reference Figures 1-3 As shown, this application discloses an electrical control box assembly, which includes a unit frame 10, an electrical control component 20, a first guide rail structure 30, and a second guide rail structure 40. The first guide rail structure 30 is placed inside and connected to the unit frame 10, and the second guide rail structure 40 is connected to the electrical control component 20. The first guide rail structure 30 and the second guide rail structure 40 are movably connected so that the electrical control component 20 can move relative to the unit frame 10.

[0024] Thus, through the movable connection between the first guide rail structure 30 and the second guide rail structure 40, the electronic control component 20 can be flexibly pulled out and moved, which greatly facilitates the daily inspection and maintenance of the electronic control component 20.

[0025] The aforementioned connection allows the electronic control assembly 20 to have at least one "push-in closed" working position and one "pull-out for inspection" maintenance position. In the pulled-out state, most of the terminals and components on the electronic control assembly 20 are fully exposed, realizing a shift from "concealed maintenance" to "direct maintenance," fundamentally improving the operator's field of vision and space.

[0026] In this embodiment, two sets of first guide rail structures 30 are provided, arranged vertically at intervals, and correspondingly, two sets of second guide rail structures 40 are also provided. The two sets of first guide rail structures 30 provide at least four support and guide points for the electronic control component 20, effectively preventing jamming, tilting, or twisting of the electronic control component 20 due to center of gravity shift during the pulling process, ensuring smooth and stable movement, and distributing the load. The first guide rail structure 30 and the second guide rail structure 40 can be, but are not limited to, ball bearing guides, roller guides, or slider guides.

[0027] Furthermore, in this embodiment, the unit frame 10 is provided with two sets of parallel and spaced-apart mounting plates 12. The mounting plates 12 are perpendicular to the first guide rail structure 30, and the first guide rail structure 30 is fixed to the mounting plate 12. In this way, by adjusting the number and installation position of the first guide rail structure 30 on the mounting plate 12, different sliding requirements can be accommodated.

[0028] Please refer to the reference again. Figure 4 As shown, the electrical control box assembly also includes a slide structure 50, which includes a guide rail 51, load-bearing rollers 52, and a support bracket 53. The guide rail 51 is fixed to the bottom of the electrical control assembly 20, and the load-bearing rollers 52 are fixed to the bottom of the unit frame 10 and slide in cooperation with the guide rail 51.

[0029] Furthermore, the shim bracket 53 is fixed to the bottom of the unit frame 10, and the load-bearing rollers 52 are fixed to the top of the shim bracket 53. The height raised by the shim bracket 53 can prevent water from entering the electrical control component 20 if water accumulates inside the electrical control box assembly.

[0030] In this embodiment, the support bracket 53 is an inverted U-shaped structure with flanges on both sides, which secure the support bracket 53 to the bottom of the unit frame 10. Thus, the inverted U-shaped support bracket 53 not only provides an installation base for the slide structure 50, but its arched space also provides a channel for the arrangement of the bottom wiring harness, avoiding the risk of damage to the wiring harness. Furthermore, to further increase the size of the arched space, a U-shaped structure recessed away from the support bracket 53 is provided at the bottom of the unit frame 10.

[0031] The electronic control box assembly also includes a transition frame 60, whose two opposite sides are connected to the electronic control component 20 and the second guide rail structure 40, respectively. Thus, the transition frame 60 acts as a crucial "adapter," enabling a modular connection between the electronic control component 20 and the second guide rail structure 40. On one hand, it effectively transfers and distributes the load of the electronic control component 20 onto the second guide rail structure 40. On the other hand, it allows the electronic control component 20 to be pre-assembled and tested as an independent unit before being integrated into the entire sliding system via the transition frame 60, significantly improving production efficiency and replacement speed during maintenance.

[0032] In this embodiment, the transition frame 60 is a square hollow frame. Openings are provided at both ends along the sliding direction of the electronic control component 20, providing channels for wire harnesses arranged along the sliding direction of the electronic control component 20.

[0033] In this embodiment, the guide rail 51 is fixed to the bottom of both the transition frame 60 and the electronic control component 20, effectively preventing the electronic control component 20 from tipping over or getting stuck during the sliding process, and significantly improving the stability of the entire movement.

[0034] In a preferred embodiment, crossbeams or reinforcing ribs may be added inside the square hollow frame structure of the transition frame 60 to improve its structural rigidity and prevent deformation when bearing heavy electronic control components 20. Furthermore, for wire harness management, standard cable clip mounting holes or Velcro cable tie holes may be pre-set on the transition frame 60. After the wire harness enters through one opening of the transition frame 60, it can be arranged along a pre-set cable routing channel on the inner side of the frame and led out from the other opening, ensuring that the wire harness is neatly arranged and does not interfere with moving parts.

[0035] The electrical control box assembly also includes a fixing rod 70, which is fixed within the unit frame 10 and located between the two sets of first guide rail structures 30. A fixing plate 61 on the transition frame 60 is detachably connected to the fixing rod 70. This detachable connection can refer to a bolted connection, a quick-release snap-fit ​​connection, or a pin connection.

[0036] When the electrical control component 20 is pushed into the unit frame 10 and reaches the working position, the fixing plate 61 on the transition frame 60 and the fixing rod 70 are fastened together, which can securely lock the electrical control component 20 inside the unit frame 10, effectively suppressing vibration during equipment operation and improving connection reliability. Furthermore, it is safer and more reliable during the transportation of the electrical control component.

[0037] The control box assembly also includes a baffle 80, which is fixed to one end of the first guide rail structure 30 and extends toward the second guide rail structure 40. Specifically, in the sliding direction of the control component 20, the baffle 80 partially overlaps with the second guide rail structure 40. In this embodiment, when the control component 20 slides into the unit frame 10, the second guide rail structure 40 contacts the baffle 80 located at the inner end of the first guide rail structure 30, thereby limiting the final sliding position of the control component 20.

[0038] Please refer to the reference again. Figure 5 As shown, the side of the unit frame 10 is provided with an opening 11 for the power control component 20 to enter and exit, and a handle 21 is provided on the side of the power control component 20. This makes it convenient for users to push and pull the power control component 20 into and out of the power control box assembly.

[0039] This application also discloses an air conditioner that includes the aforementioned electrical control box assembly. The air conditioner referred to herein can be an outdoor unit of a unitary air conditioner, an air-cooled heat pump unit, or a large multi-split unit; no specific limitation is made herein.

[0040] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
