Description

Technical Field

[0001] This utility model relates to the field of wired controller technology, specifically to a modular wired controller housing system and a wired controller. Background Technology

[0002] Wired controllers, especially those used in home appliances such as air conditioners, typically need to be adaptable to various installation scenarios, such as placement on a desktop, embedding in a wall junction box (86 box), or mounting on the sheet metal of a specific device. Existing wired controllers mostly have a single-structure housing, with one housing corresponding to only one installation method. If a user needs to change the installation method, they must replace the entire wired controller or use a complex and unsightly adapter bracket.

[0003] For example, utility model patent CN215372870U proposes a wired controller with a portion of the housing protruding into the electrical box to reduce external thickness. However, its fixed structure cannot adapt to installation scenarios where wall mounting is not required. Utility model patent CN220915587U provides a mounting bracket reinforcement and locking device, which optimizes installation stability but adds extra mounting components, resulting in a complex structure, increased cost, and failing to address the fundamental problem of limited installation options.

[0004] Therefore, there is an urgent need in this field for a wired controller housing solution that can flexibly adapt to various installation requirements, has a simple structure, and is inexpensive. Utility Model Content

Detailed Implementation

[0033] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the embodiments described herein are only some, not all, of the embodiments of this utility model, and are merely used to explain the present utility model and are not intended to limit the present utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figure 1-4As shown, this utility model provides a modular wired controller housing system, including a front cover 1 and at least two replaceable rear covers, including a first rear cover 2A and a second rear cover 2B. The front cover 1 can be selectively combined with either the first rear cover 2A or the second rear cover 2B to form a wired controller assembly with different installation configurations. The first rear cover 2A is configured to form an independent desktop wired controller housing. The second rear cover 2B integrates an installation interface for fixing to a mounting structure on a building wall. Through the replaceable combination of the front cover 1 and at least two rear covers (first rear cover 2A, second rear cover 2B), wired controllers with different installation configurations can be constructed. Users or manufacturers do not need to prepare multiple completely different products; they can adapt to various scenarios such as desktop use and wall mounting simply by replacing the core module (rear cover). This greatly improves the product's market adaptability and user convenience, solving the limitation of traditional wired controllers where one housing corresponds to one installation method, and achieving true modularity and multi-functionality.

[0035] In some specific embodiments, the mounting interface includes at least one mounting plate position for detachably connecting a mounting plate; and / or, at least a pair of screw holes 22 penetrating the front cover and / or rear cover. These correspond to two mainstream installation methods: mounting plate installation and direct 86-type junction box installation, providing installation options and compatibility to meet different user installation preferences and site conditions. Mounting plate installation facilitates repeated disassembly and adjustment. The screw holes 22 allow fasteners to pass directly through and be fixed to the junction box within the wall, while direct screw fixing is simpler, more direct, and structurally more robust.

[0036] In some specific embodiments, the mounting plate includes a first limiting part 211 and a second limiting part 212. The mounting plate is provided with a snap-fit ​​structure adapted to the mounting plate mounting position. The mounting plate slides into the second limiting part 212 and engages with the first limiting part 211 through the snap-fit ​​structure, thereby achieving the snap-fit ​​locking of the second rear cover 2B and the mounting plate. The mounting plate mounting position adopts a sliding snap-fit ​​structure with first and second limiting parts, realizing quick installation of "alignment, sliding down, and locking". The main body can be fixed without tools, greatly improving installation efficiency and user experience.

[0037] In some specific embodiments, the front cover 1 and / or the rear cover are provided with one or more screwdriver insertion ports 25. By inserting a tool into the screwdriver insertion port 25 and rotating it, the second rear cover 2B, which is already installed on the wall, can be pushed out and removed. Installers no longer need to blindly pry it with tools, avoiding the risk of damaging the product's appearance and internal clips, and reducing the difficulty and cost of after-sales maintenance.

[0038] In some specific embodiments, the first back cover 2A is provided with a cable routing groove 21 and / or a program flashing interface 27, which optimizes cable management in desktop usage scenarios and keeps things tidy; the reserved flashing interface facilitates production debugging and later firmware upgrades without opening the shell.

[0039] In some specific embodiments, the second rear cover 2B is provided with a heat dissipation grille 23, which effectively improves the heat dissipation capacity of the wired controller in a closed or semi-closed environment (such as inside a wall box), prevents internal components from being damaged or having their lifespan reduced due to overheating, and improves the long-term reliability of the product.

[0040] In some specific embodiments, the second rear cover 2B is provided with a clearance groove 24 to ensure that the wired controller can be installed tightly and flat against the wall, avoiding the problem that the outer shell cannot be installed properly or is deformed due to messy cables or protruding connectors in the wall box.

[0041] Furthermore, the second rear cover 2B is provided with a wiring position 29 to facilitate the introduction of wiring structures such as wiring terminals. The second rear cover 2B also contains a circuit board mounting base 20 for fixing and installing the built-in circuit board.

[0042] In some embodiments, the second rear cover 2B can also be combined with a small cover plate 3 to form an independent power supply housing, wherein the small cover plate 3 is detachably mounted on the second rear cover 2B. This greatly expands its application scenarios for non-wired controller uses. It significantly broadens the application scope of the core module (second rear cover 2B), transforming it from a simple wired controller component into a universal power supply or controller housing, which can be used in cabinets, equipment interiors, and other scenarios, achieving multi-purpose functionality.

[0043] In some embodiments, at least one edge region of the small cover plate 3 includes a separable structure 34. When installation space is limited or structural interference exists, installers can "customize" the shell shape as needed, ensuring smooth product installation, reducing the need for returns or modifications due to size issues, and providing extremely high field adaptability.

[0044] This utility model also provides a wired controller, including the modular wired controller housing system as described above, and a circuit board and control elements housed therein.

[0045] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of some embodiments of this utility model will be described in further detail below.

[0046] Example 1:

[0047] When the user needs to use the wired controller as a desktop device, the front cover 1 and the first rear cover 2A are fastened together. The first rear cover 2A has a simple structure and a flat bottom, allowing it to be placed stably on a desktop, forming a complete ordinary wired controller. The first rear cover 2A may also be equipped with a program flashing interface 27, which has a corresponding sealing plate structure to facilitate program updates or debugging of the internal circuitry.

[0048] Example 2:

[0049] When the user needs to install the wired controller on a wall, the second rear cover 2B should be used in combination with the front cover 1. The back of the second rear cover 2B integrates a variety of mounting structures:

[0050] Mounting plate installation: First, fix the mounting plate to the wall with screws. Then, align the mounting plate mounting position 21 on the back of the second rear cover 2B with the buckle structure on the mounting plate, slide it downwards, and let the narrow part of the buckle structure slide into the second limiting part 212 on the mounting plate mounting position 21, slide it into the first limiting part 211 to lock it in place.

[0051] Direct installation: Alternatively, you can choose not to use the mounting plate and directly pass the screws through the screw holes 26 on the second rear cover 2B to fix it to the 86 junction box pre-embedded in the wall.

[0052] Easy disassembly: After installation, if disassembly is required, insert a screwdriver or other tool into the screwdriver insert 25 and gently twist it. Use the lever principle to push the back cover out without the need for violent prying, thus protecting the product's appearance.

[0053] Heat dissipation and compatibility: Heat dissipation grille 23 ensures heat dissipation for internal components. Recessed groove 24 provides space for screws passing through mounting holes 26 (i.e., screw holes 22), ensuring installation compatibility.

[0054] Example 3:

[0055] The second rear cover 2B can also be used independently with the small cover plate 3, without being combined with the front cover 1. The small cover plate 3 is fixed to the second rear cover 2B by clips or screws. Specifically, it can be engaged by the key 28 on the second rear cover 2B and the slot 32 on the small cover plate 3 to form a sealed box. This box can be used to house a power module or other circuits. The cable outlet 31 on the small cover plate 3 is used to lead out cables.

[0056] Furthermore, the separable structure 34 on the edge of the second rear cover 2B (such as having pre-set easy-break ribs or engraved lines) allows for easy installation onto the sheet metal of a cabinet. Correspondingly, it can be secured with screws using the mounting holes 26 on the second rear cover 2B and the mating holes 33 on the small cover plate 3. Alternatively, depending on the limitations of the actual installation space, part of its edge can be broken off to change its shape and adapt to special installation requirements.

[0057] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
