[0067] The distribution boxes of new-generation smart devices (such as smart building equipment) are often equipped with controllers. These controllers can be used to control smart building equipment (such as air conditioners and elevators). However, due to limitations in installation space and environment, the controllers need to be installed flexibly.

[0068] In some embodiments of this application, the controller can be a DDC controller (Direct Digital Controller) or a PLC controller (Programmable Logic Controller). The controller can be used to control systems and equipment such as air conditioning systems, hot water systems, fresh air systems, lighting systems, and elevator systems.

[0069] Referring to Figure 1, some embodiments of this application propose a controller 1000, which includes a housing 100 and a main control board 170. The housing 100 forms the exterior of the controller 1000, and an accommodating space (not shown) is formed inside the housing 100, within which the main control board 170 is disposed.

[0070] In some embodiments of this application, the housing 100 may include an upper housing 110, a lower housing 120, and a maintenance cover 190. The upper housing 110 and the lower housing 120 are connected and enclose the receiving space. A maintenance opening (not shown) is provided on the front of the upper housing 110. The maintenance cover 190 is pivotally and flip-mounted onto the upper housing 110 to cover / expose the maintenance opening. During maintenance, the maintenance personnel flip the maintenance cover 190 to expose the maintenance opening and perform maintenance or repair operations on the electrical components in the receiving space through the maintenance opening, such as resetting, copying data, etc. After the maintenance is completed, the maintenance cover 190 is flipped to cover the maintenance opening.

[0071] In some embodiments of this application, the controller 1000 can be mounted on either the guide rail 2000 or a wall. It should be noted that the wall can be a vertical wall or an inclined wall, and the guide rail 2000 can be adhered to the wall or fixed to the wall using threaded fittings. In some embodiments of this application, to facilitate wall mounting and guide rail mounting of the controller 1000, referring to Figures 2 and 3, the back of the housing 100 is provided with wall mounting holes 123 / 123A and a clearance portion 121 for the guide rail 2000, which accommodates the guide rail 2000. When the housing 100 includes an upper housing 110 and a lower housing 120, the back of the housing 100 refers to the back of the lower housing 120. It should be noted that after the controller 1000 is installed, the surface facing the user is the front of the housing 100, and the surface opposite to this front is the back of the housing 100. In some embodiments of this application, for ease of description, the direction of the straight line arrow shown in FIG2 is the length extension direction of the straight line arrow, which is denoted as left and right extension. The first side of the straight line arrow is the upper side and the second side of the straight line arrow is the lower side.

[0072] Referring to Figure 3, the clearance portion 121 has a bottom wall 1211, an upper side wall 1212 that abuts the first edge of the bottom wall 1211, and a lower side wall 1213 that abuts the second edge of the bottom wall 1211. Referring to Figure 3, the corresponding guide rail 2000 has a central U-shaped portion 2100 and first flanges 2200 and second flanges 2300 located on both sides of the central U-shaped portion 2100. Both the first flanges 2200 and the second flanges 2300 extend away from the central U-shaped portion 2100. The central U-shaped portion 2100 is formed by the bottom wall 1211 and the two side walls (upper side wall 1212 / lower side wall 1213), forming a continuous groove structure with a U-shaped cross-section. This geometric feature complements the clearance portion 121 of the controller housing 100, achieving mechanical adaptation between the guide rail and the controller. The U-shaped opening is perpendicular to the installation direction of the controller, and the bottom wall 1211 provides the main load-bearing support; the two side walls form mechanical constraints to limit the lateral displacement of the controller on the guide rail; the arc transition design of the U-shaped structure can improve stress distribution and avoid local stress concentration.

[0073] In some embodiments of this application, referring back to FIG2, the controller 1000 further includes a clamping portion and at least one fixing portion 125 formed on the housing 100. Referring to FIG2, the clamping portion and at least one fixing portion 125 are both formed on the back side of the lower housing 120. In some embodiments of this application, the fixing portion 125 and the clamping portion are integrally formed with the lower housing 120. In some embodiments of this application, referring to FIG2 and FIG3, the clamping portion may include a latching protrusion 124, which is disposed on the upper sidewall 1212 of the clearance portion 121 and protrudes toward the lower sidewall 1213 of the clearance portion 121, such that a first gap (not labeled) is formed between the latching protrusion 124, the upper sidewall 1212 and the bottom wall 1211 of the clearance portion 121, for engaging the first flange 2200 of the guide rail. In some embodiments of this application, the number of the latching protrusion 124 can be one or more. When there is one latching protrusion 124, its length extends along the length direction of the avoidance portion 121. When there are multiple latching protrusions 124, they are spaced apart on the upper sidewall 1212 of the avoidance portion 121.

[0074] Referring to Figure 4, in some embodiments of this application, the back of the fixing part 125 has a mounting part 1252, and the portion extending beyond the housing 100 forms a through-hole part 1251. In some embodiments of this application, the controller 1000 further includes a deformable part 130 that can be mounted to the mounting part 1252, and the deformable part 130 can be mounted on the fixing part 125 via the mounting part 1252. When the deformable part 130 is mounted to the corresponding mounting part 1252, the end of the deformable part 130 near the clearance part 121 forms a locking part 132 that extends into the clearance part 121, such that a second gap (not labeled) is formed between the locking part 132 of the deformable part 130, the bottom wall 1211 of the clearance part 121 and its lower side wall 1213, for engaging the second flange 2300 of the guide rail 2000. At least one fixing part 125 as described above can be described in the following two cases.

[0075] In some embodiments of this application, when a fixing part 125 (denoted as the first fixing part 125) is present, the plurality of latching protrusions 124 and the first fixing part 125 are arranged opposite to each other on both sides of the clearance part 121. The plurality of latching protrusions 124 are spaced apart along the length of the clearance part 121 on the first side of the clearance part 121, and the wall mounting holes 123 / 123A and the plurality of latching protrusions 124 are all located on the same side of the clearance part 121. A deformable part 130, denoted as the first deformable part, is installed in the mounting part 1252 of the first fixing part. When assembling the controller 1000 using a guide rail, the plurality of latching protrusions 124 clamp the first flange 2200 of the guide rail, and the first deformable part engages the second flange 2300 of the guide rail. During wall-mounted fastening, a first fastener passes through the through-part 1251 of the first fixing part and is fixed to the wall. When wall-mounted, a second fastener fixed to the wall using wall-mounting holes 123 / 123A is used to achieve wall-mounting. In some embodiments of this application, wall-mounting holes 123 / 123A can be closed holes or holes open at the bottom. In some embodiments of this application, for ease of mounting, wall-mounting holes 123 / 123A are set as holes open at the bottom. Referring to Figure 2, wall-mounting holes 123 / 123A extend upward from the upper side wall 1212 of the clearance part 121, and wall-mounting holes 123 / 123A communicate with the clearance part 121. When mounting the controller 1000, the second fastener is more easily inserted into the wall-mounting hole 123 / 123A through the lower part communicating with the clearance part 121. In some embodiments of this application, referring to Figure 2, there are two wall-mounting holes 123 / 123A, and the two wall-mounting holes 123 / 123A are arranged at intervals along the left and right extension direction of the clearance part 121.

[0076] In some embodiments of this application, to enhance the stability of the controller 1000 wall-mounted installation, when using wall-mounting holes 123 / 123A, a third fastener passes through the through-hole 1251 of the first fixing part, achieving a combination of suspension and fixing to secure the controller 1000 to the wall. In some embodiments of this application, referring to FIG2, the fixing part 125 and the two wall-mounting holes 123 / 123A form a triangle to stably fix the controller 1000. In some embodiments of this application, the number of wall-mounting holes 123 / 123A can be flexibly set. The first, second, and third fasteners can be screws or unthreaded pins.

[0077] In some embodiments of this application, when multiple fixing parts 125 exist, the multiple latching protrusions 124 and some of the fixing parts 125 (denoted as at least one first fixing part) are arranged opposite to each other on both sides of the clearance part 121. The multiple latching protrusions 124 are arranged on the first side of the clearance part 121, and at least one first fixing part is arranged on the second side of the clearance part 121. The remaining fixing parts 125 can be arranged on the same side as the multiple latching protrusions 124. The wall mounting holes 123 / 123A and the multiple latching protrusions 124 are all located on the same side of the clearance part 121. A deformation part 130, denoted as a first deformation part, is installed in the mounting part 1252 of each first fixing part. When assembling the controller 1000 using the guide rail, the multiple latching protrusions 124 clamp the first flange 2200 of the guide rail, and the first deformation part engages the second flange 2300 of the guide rail. When wall-mounted, a first fastener passes through the through-part of the first fixing part, and / or a second fastener passes through the through-part 1251 of at least one of the remaining fixing parts 125 to secure it to the wall. In some embodiments of this application, to enhance the stability of the controller 1000 wall-mounted installation, when using the wall mounting holes 123 / 123A, a fourth fastener passes through the through-part 1251 of at least one of the first fixing parts and / or the through-part 1251 of at least one of the remaining fixing parts 125, thereby securing the controller 1000 to the wall using a combination of suspension and fixation.

[0078] In some embodiments of this application, the fixing part 125 and the clamping part can be integrally formed with the lower housing 120. In some embodiments of this application, at least one deformable part is installed in the mounting part 1252 of at least one fixing part located on a different side from the clamping part 121. In some embodiments of this application, a first limiting recess 1253 is provided on the bottom wall 1211 of the mounting part 1252, and correspondingly, a first limiting protrusion is provided on the deformable part 130. When the deformable part 130 is installed to the mounting part 1252, the first limiting protrusion is inserted into the first limiting recess 1253, thus achieving installation in place. Referring to FIG5, in some embodiments of this application, the first limiting recess 1253 is a limiting groove, and correspondingly, the first limiting protrusion is a limiting protrusion 1343. In some embodiments of this application, both the deformable part 130 and the first limiting protrusion are made of deformable material. In some embodiments of this application, the deformable part 130 and the first limiting protrusion are integrally formed. In some embodiments of this application, in order to enable the guide rail 2000 to be snapped into the clearance part 121, the material of the deformable part 130 and the material of the first limiting protrusion are both deformable materials. After the first flange 2200 of the guide rail 2000 is snapped into the clamping part, when the second flange 2300 applies external force to it, the deformable part 130 is deformed due to the deformable limiting protrusion 1343, and finally the guide rail is snapped into the locking part 132, thus completing the snapping of the guide rail 2000.

[0079] In some embodiments of this application, referring to FIG4, to facilitate the guide rail 2000 engaging with the clearance portion 121, a guide surface 133 is formed on the side of the engaging portion 132 of the deformable portion 130 away from the clearance portion 121. This guide surface 133 is inclined towards the clearance portion 121 for guidance. When the user applies external force to the side where the second flange 2300 of the guide rail 2000 is located, the guide surface 133 guides the guide rail 2000, facilitating its engagement with the engaging portion 132. In some embodiments of this application, a cantilever-shaped limiting protrusion 1343 is formed to facilitate the deformation of the deformable portion 130. Referring to FIGS. 4 and 5, the deformable portion 130 has a cantilever 134 and a through hole 135. The cantilever 134 is disposed within the through hole 135 to provide deformation space for the cantilever 134. In some embodiments of this application, the cantilever 134 includes a connecting arm 1341 and a limiting arm 1342. The end of the connecting arm 1341 connected to the deformable part 130 is a fixed end, and the suspended end is a free end. The limiting arm 1342 is formed at the free end, and the portion of the limiting arm 1342 extending out of the deformable part 130 and facing the bottom plane of the mounting part 1252 forms the limiting protrusion 1343. Due to the through hole 135 and the cantilever 134, the elastic deformation force of the deformable part 130 is increased, so that when an external force is applied to the guide rail 2000, only a small external force is needed to deform the deformable part 130 and engage the second flange 2300 of the guide rail 2000 into the locking part 132. Furthermore, the through hole 135 and cantilever 134, while ensuring that the deformable part 130 is easy to deform, also reduce the thickness of the deformable part 130 in the direction perpendicular to the length of the mounting part 1252, thereby reducing cost and reducing the overall size of the controller 1000. In some embodiments, the cantilever 134 may be a deformable cantilever.

[0080] In some embodiments of this application, the deformable portion 130 is slidably installed into the mounting portion 1252 via a sliding fit. In some embodiments of this application, referring to FIG4, the mounting portion 1252 extends through the deformable portion 130 along its sliding direction. When the deformable portion 130 is installed into the mounting portion 1252, the locking portion 132 extends from the end of the mounting portion 1252 near the clearance portion 121 (denoted as the first end) and into the clearance portion 121. The end of the mounting portion 1252 opposite to the first end, away from the clearance portion 121 (denoted as the second end), forms the mounting opening 1255 of the mounting portion 1252. In some embodiments of this application, a slider 1254 is formed on the inner wall of the mounting portion 1252 of the fixing portion 125. Correspondingly, slide rails 131 that cooperate with the slider 1254 are formed on both sides of the deformable portion 130. When the deformable part 130 is slidably installed to the mounting part 1252, the first limiting protrusion is embedded in the first limiting recess 1253, thus achieving slid installation in place.

[0081] In some embodiments of this application, referring to FIG5, the free end of the limiting protrusion 1343 forms an inclined limiting guide surface 1344 at the front end along the sliding direction of the deformable portion 130, and the limiting guide surface 1344 forms an acute angle with the bottom wall 1211 of the mounting portion 1252. When the deformable portion 130 extends into the mounting opening 1255 of the mounting portion 1252 and slides within the mounting portion 1252, the limiting guide surface 1344 reduces the friction between the deformable portion 130 and the bottom wall 1211 of the mounting portion 1252, and at the same time facilitates the guiding of the limiting protrusion 1343 into the first limiting recess 1253 of the bottom wall 1211 of the mounting portion 1252. In some embodiments of this application, in order to facilitate the insertion of the limiting protrusion 1343 into the mounting opening 1255 of the mounting portion 1252, a clearance notch 1256 is formed at the mounting opening 1255 of the mounting portion 1252 to avoid the limiting protrusion 1343.

[0082] In some embodiments of this application, the free end of the limiting protrusion 1343 can form an inclined limiting guide surface 1344 at the front end along the sliding direction of the deformable part 130. Referring to FIG4, a clearance notch is formed at the mounting opening 1255 of the mounting part 1252 to avoid the limiting protrusion 1343. The clearance notch forms an inclined guide surface that matches the limiting guide surface 1344, facilitating the sliding of the limiting protrusion 1343 into the mounting part 1252. Furthermore, the cooperation between the limiting guide surface 1344 and the clearance notch also helps to achieve accurate positioning of the deformable part 130.

[0083] In some embodiments of this application, the deformable part 130 is an independent component that can be mass-produced. During use, the number of deformable parts 130 can be selected based on the number of fixing parts 125 on the housing 100 corresponding to the clamping part. In use, each deformable part 130 is installed into its corresponding mounting part 1252. The first flange 2200 of the guide rail 2000 is inserted obliquely into the first gap formed by the clamping part and the clearance part 121, completing the snap-fit ​​of the first flange 2200. Then, an external force is applied to the side where the second flange 2300 of the guide rail 2000 is located, causing each deformable part 130 to deform. The second flange 2300 then snaps into the second gap formed by the locking part 132 and the clearance part 121, completing the snap-fit ​​of the second flange 2300. Simultaneously, the deformable part 130 completes its deformation recovery, and the elastic recovery force also applies force to the guide rail 2000, ensuring that the guide rail 2000 is stably positioned in the clearance part 121.

[0084] In some embodiments of this application, the upper housing 110 and the lower housing 120 are connected by a plurality of first snap-fit ​​structures arranged circumferentially. Referring to Figure 6, the first snap-fit ​​structure includes a buckle and a slot. The slot can be provided on the upper housing 110, and the corresponding buckle can be provided on the lower housing 120, or the slot can be provided on the lower housing 120, and the corresponding buckle can be provided on the upper housing 110. In some embodiments of this application, a plurality of lifting lugs 112 are arranged circumferentially at intervals on the upper housing 110. Each lifting lug 112 has a slot. Correspondingly, buckles 126 are provided at corresponding positions circumferentially on the lower housing 120. When the upper housing 110 is fastened onto the lower housing 120, the buckles 126 are engaged in the slots, realizing the snap-fit ​​connection between the upper housing 110 and the lower housing 120. In some embodiments of this application, a first clearance opening (not shown) is provided at the connection position between the upper housing 110 and the lower housing 120 to avoid the wiring terminal. Through the first clearance opening, the wiring terminal is connected to the main control board 170 and is located outside the housing 100. The first clearance opening can be provided on the upper housing 110 or on the lower housing 120.

[0085] In some embodiments of this application, referring to Figures 6 and 17, the housing 100 of the controller 1000 has a square design, and multiple first snap-fit ​​structures are disposed at the four corners of the upper housing 110 and the lower housing 120. To prevent the upper housing 110 and the lower housing 120 from warping at the connection position, multiple second snap-fit ​​structures are also provided at the connection position. These second snap-fit ​​structures can be disposed between two adjacent first snap-fit ​​structures located on one side of the clearance portion 121. In some embodiments of this application, the second snap-fit ​​structure includes a buckle and a slot. The slot can be disposed on the upper housing 110, and the corresponding buckle can be disposed on the lower housing 120; or the slot can be disposed on the lower housing 120, and the corresponding buckle can be disposed on the upper housing 110. In some embodiments of this application, an anti-tilting lug 113 is provided on the portion of the upper housing 110 located on the side of the clearance portion 121. The anti-tilting lug 113 has an anti-tilting slot. Correspondingly, an anti-tilting buckle 127 corresponding to the anti-tilting lug 113 is provided on the portion of the lower housing 120 located on the side of the clearance portion 121. When the upper housing 110 is fastened onto the lower housing 120, the anti-tilting buckle 127 is engaged in the anti-tilting slot, thereby achieving a snap-fit ​​connection between the upper housing 110 and the lower housing 120 and preventing anti-tilting at the middle position between the upper housing 110 and the lower housing 120.

[0086] In some embodiments of this application, for ease of wiring, referring to FIG1, the terminals described above are located on one or both sides of the clearance portion 121, and the number is flexibly set according to wiring requirements. These terminals can be used for signal (e.g., communication signals, control signals) transmission, power supply, etc. Terminals used for transmitting communication signals are called communication terminals, for example, communication terminal 140. In some embodiments of this application, to facilitate the extended communication and control of the controller 1000, the controller 1000 can be extended to connect multiple expansion modules as needed (see FIG7, for example, expansion module 1000'). For example, when four expansion modules exist, the first expansion module is configured to output signals controlling the air conditioning system, the second expansion module is configured to output signals controlling the hot water system, the third expansion module is configured to output signals controlling the lighting system, and the fourth expansion module is configured to output signals controlling the elevator system. That is, the communication signal from the controller 1000 is used to control the air conditioning system through the extended connection with the first extension module, to control the hot water system through the extended connection with the first and second extension modules, to control the lighting system through the extended connection with the first, second and third extension modules, and to control the elevator system through the extended connection with the first, second, third and fourth extension modules.

[0087] In some embodiments of this application, the housing of the expansion module is configured to have the same structure as the housing of the controller 1000 as described above, that is, it can be installed either on a DIN rail or on a wall. In some embodiments of this application, in order to meet the connection requirements of the controller 1000 and the expansion module under various installation conditions (e.g., DIN rail installation, wall mounting), referring to Figures 7 and 8, and in conjunction with Figure 9, in addition to the communication terminals as described above, an expansion adapter 3000 for expansion is also provided. This expansion adapter 3000 and the controller 1000 form a controller assembly. Using this expansion adapter 3000, the controller 1000 installed on the same DIN rail 2000 and an adjacent expansion module, such as expansion module 1000', can be connected, or two adjacent expansion modules installed on the same DIN rail 2000 can be connected.

[0088] In some embodiments of this application, the housing 100 of the controller 100 forms two second clearance openings at both ends of the clearance portion 121 along its length extension direction to accommodate the extension adapter 3000 (see FIG. 8, which shows one second clearance opening 160 on the right). In some embodiments of this application, since the housing of the expansion module 1000' has the same structure as the housing of the controller 1000, the housing of the expansion module 1000' forms two third clearance openings at both ends of its clearance portion along its length extension direction to accommodate the extension adapter 3000 (see FIG. 7, which shows one third clearance opening 160' on the right). In some embodiments of this application, as described above, the upper housing 110 and the lower housing 120 of the controller 1000 form the second clearance opening 160 at their connection positions along the length extension direction of the clearance portion 121. The second clearance opening 160 can be disposed on the upper housing 110 of the controller 1000, or on the lower housing 120 of the controller 1000, or partially disposed on the upper housing 110 and partially disposed on the lower housing 120 of the controller 1000. In some embodiments of this application, the third clearance opening is formed at the connection position of the upper housing and the lower housing of the expansion module 1000' in the length extension direction of their clearance portion. The third clearance opening can be disposed on the upper housing of the expansion module or on the lower housing of the expansion module.

[0089] Referring to Figure 9, an expansion adapter 3000 connects to the main control board 170 of the adjacent controller 1000 and the main control board 170' of the expansion module 1000' via a second clearance opening 160 on the controller 1000 and a third clearance opening on the adjacent expansion module 1000', respectively, thus realizing the expansion connection between the controller 1000 and the adjacent expansion module 1000'. Another expansion adapter 3000 connects to the main control boards of two adjacent expansion modules via a third clearance opening on one expansion module and a third clearance opening on another adjacent expansion module, thus realizing the expansion connection between adjacent expansion modules. In some embodiments of this application, the structure of the expansion adapter 3000 is described as an example of the expansion adapter 3000 connecting the main control board 170 of the adjacent controller 1000 and the main control board 170' of the expansion module 1000'.

[0090] Referring to Figures 9 and 10, the expansion adapter 3000 includes a first expansion port 3100 and a second expansion port 3200 arranged opposite to the first expansion port 3100. The first expansion port 3100 and the second expansion port 3200 are located on the same straight line, which is parallel to the length extension direction of the clearance portion 121. The opening directions of the first expansion port 3100 and the second expansion port 3200 are opposite and electrically connected to each other. The first expansion port 3100 extends into the second clearance opening 160 of the controller 1000 to electrically connect to the communication point on the main control board 170 of the controller 1000 for expansion. The second expansion port 3200 extends into the third clearance opening 160' of the adjacent expansion module 1000' to electrically connect to the communication point on the main control board 170' of the expansion module 1000'. In some embodiments of this application, the first expansion port 3100 and the second expansion port 3200 are clamped and electrically connected to the corresponding main control board at the same time by clamping the corresponding main control board.

[0091] In some embodiments of this application, referring to FIG10, the first expansion port 3100 includes a first clamping part 3112. A portion of the main control board 170 of the controller 1000 with communication points extends into the first expansion port 3100. The electrical contacts on the first clamping part 3112 are electrically connected to and clamp the communication points on the main control board 170. The second expansion port 3200 includes a second clamping part (not labeled). Another portion of the main control board 170' of the expansion module 1000' with communication points extends into the second expansion port 3200. The electrical contacts on the second clamping part are configured to electrically connect to the communication points of the expansion module 1000' and clamp the main control board 170' of the expansion module 1000'. In some embodiments of this application, referring to FIG10, the first expansion port 3100 also includes a first insertion part 3111 and a first receiving part 3113. The first insertion portion 3111, the first clamping portion 3112, and the first receiving portion 3113 are sequentially connected through their opening (denoted as the first opening). For example, a portion of the main control board 170 of the controller 1000 with communication points can be inserted through the first opening, pass through the first insertion portion 3111, and extend into the first receiving portion 3113, so that the communication points are electrically connected to the electrical contact points of the first clamping portion 3112 while being clamped. In some embodiments of this application, referring to FIG10, the first clamping portion 3112 is located between the first receiving portion 3113 and the first insertion portion 3111, gradually narrowing from the first insertion portion 3111 to the first clamping portion 3112 and gradually widening from the first clamping portion 3112 to the first receiving portion 3113. In this way, the first clamping portion 3112 is used to clamp the main control board 170 while simultaneously achieving electrical connection with the communication points.

[0092] In some embodiments of this application, the electrical contact can be a set of cantilever beam elastic contacts. Each contact includes a fixed end and a free end. The fixed end is securely embedded or fixed inside the housing of the expansion port, for example, by injection molding. The free end extends into the channel to form a contact arm. The end of the contact arm forms a smooth, protruding contact point into the channel for contacting the communication pads of the main control board 170. When the main control board 170 is inserted, its surface presses against the contact point, causing the entire contact arm to elastically bend with its fixed end as the fulcrum. The electrical contact can also be designed as a hyperboloid spring socket. This structure consists of multiple bundles of elastic metal wires arranged according to a hyperboloid pattern, forming a socket. The edge of the main control board acts as a pin inserted into the spring socket. When the edge of the main control board is inserted, it simultaneously forms line contact with the surrounding multiple elastic metal wires.

[0093] In some embodiments of this application, the communication points can be a set of flat pads. These pads are copper foil areas formed on the printed circuit board of the main control board 170, and they are connected to the surface wiring of the PCB. This set of pads is linearly arranged along the edge of the main control board 170 at a predetermined spacing, and their position, number, and spacing correspond to the layout of the electrical contacts within the expansion port. In some embodiments of this application, the communication points can be a series of elongated, rectangular, parallel conductive pads.

[0094] In some embodiments of this application, the first expansion port 3100 and the second expansion port 3200 have the same structure. Therefore, in use, as long as the communication points of the main control board that communicate with each other are corresponding, there is no need to distinguish between the first expansion port 3100 and the second expansion port 3200 of the expansion adapter 3000, which is convenient for users.

[0095] The first expansion port 3100 and the second expansion port 3200 have basically the same structure and function, and are configured to be electromechanically connected to the main control boards 170 and 170' of two adjacent modules (e.g., controller 1000 and expansion module 1000'), respectively. The following description uses the first expansion port 3100 as an example, and the description also applies to the second expansion port 3200. In some embodiments of this application, the first expansion port 3100 has an integrated channel structure that integrates guiding, clamping, positioning, and electrical connection functions. From its opening inwards, the channel sequentially includes a first insertion part 3111, a first clamping part 3112, and a first receiving part 3113. The first insertion part 3111 is located at the entrance end of the first expansion port 3100, and its inner wall gradually narrows inwards from the port, forming a guiding slope or flared structure. With this structure, when the user inserts the edge of the main control board 170 into the first expansion port 3100, the first insertion part 3111 can automatically guide and correct the position of the main control board 170. Even if there is a certain deviation in the initial alignment, it can ensure that the main control board 170 smoothly enters the subsequent clamping channel. This design greatly reduces the difficulty of installation and the requirements for the operator's alignment accuracy, improves installation efficiency, and effectively avoids forced insertion and removal due to misalignment, thereby protecting the main control board 170 and the electrical contact points inside the expansion port from damage. The first clamping part 3112 is connected to the first insertion part 3111, and the width of its channel is designed to be slightly smaller than the nominal thickness of the main control board 170. When the main control board 170 is pushed in, the sidewall of the first clamping part 3112 will undergo elastic deformation, thereby applying a continuous positive clamping force to the two main surfaces of the main control board 170. This clamping force provides reliable mechanical fixation to the main control board 170, preventing it from loosening due to vibration or unexpected external forces. Furthermore, it provides stable and sufficient positive contact pressure between the electrical contact points on the inner wall of the first clamping portion 3112 and the communication points on the main control board 170, a prerequisite for establishing a low-resistance, high-reliability electrical connection. The first receiving portion 3113 communicates with the end of the first clamping portion 3112, and its channel width is greater than or equal to the width of the first clamping portion 3112. This structure, serving as the end point of the insertion stroke of the main control board 170, acts as over-insertion protection, ensuring that the communication points on the main control board 170 accurately stop at the contact positions corresponding to the electrical contact points within the first clamping portion 3112. Simultaneously, the wider receiving portion also provides stress relief space at the end of the main control board 170.

[0096] In some embodiments of this application, referring to Figures 7 and 9, when the controller 1000 and multiple expansion modules (e.g., expansion modules 1000') are sequentially mounted on the guide rail 2000 along its length, the expansion adapter 3000 is used to realize signal transmission between adjacent controllers 1000 and expansion modules 1000', as well as between two adjacent expansion modules. In use, the controller 1000 can be mounted on the guide rail 2000 first, and the first expansion port 3100 of the expansion adapter 3000 can be connected to the main control board 170 of the controller 1000. Then, the adjacent expansion module 1000' is mounted on the guide rail 2000, and the expansion module 1000' is moved on the guide rail 2000 so that the second expansion port 3200 of the expansion adapter 3000 is connected to the main control board 170' of the expansion module 1000'. This connection method, which uses the extension adapter 3000 for communication expansion, eliminates the need for manual connection of each communication cable, saving workload and achieving high-efficiency wiring. Furthermore, it eliminates the need to pay excessive attention to the wiring position when connecting adjacent modules.

[0097] In some embodiments of this application, when installation space is limited and the controller 1000 and expansion module 1000' cannot be mounted on a rail (e.g., wall-mounted), the controller 1000 and expansion module 1000', or the expansion modules, are connected via corresponding communication terminals 140. In some embodiments of this application, when installation space is limited and only the controller 1000 can be mounted on a rail, expansion modules not mounted on a rail are connected to the controller 1000 or its adjacent expansion modules via their communication terminals. In some embodiments of this application, when installation space is limited and only the controller 1000 and some expansion modules can be mounted on a rail, expansion modules not mounted on a rail are connected to adjacent expansion modules via their communication terminals. Through the communication terminals 140 and the expansion adapter 3000, the expansion needs of the controller 1000 under different installation conditions can be met, providing users with flexible expansion connection solutions.

[0098] In some embodiments of this application, the controller 1000 may omit the clamping part, fixing part 125, and deformation part 130 as described above, and instead provide multiple connecting parts 200 / 200A / 200B. Referring to Figures 11 and 14, the multiple connecting parts 200 / 200A / 200B are also respectively mounted on the back of the housing 100 and can switch between a first position and a second position. The connecting parts 200 / 200A / 200B have the same structure, and the mechanism of the connecting part 200 will be described as an example. Referring to FIG12, the connecting portion 200 is provided with a through portion 220 (e.g., a mounting hole). When the connecting portion 200 is in the first position, the through portion 220 is at least partially covered by the housing 100 (see FIG11 and FIG12), that is, the through portion 220 is not fully exposed, and the through portion 220 cannot be used at this time. When the connecting portion 200 is in the second position (see FIG13), the through portion 220 extends beyond the housing 100 to fully expose the through portion 220, and the through portion 220 can be used at this time.

[0099] In some embodiments of this application, the multiple connecting portions are divided into two parts: a first part and a second part, each part including at least one connecting portion. The first part and the second part are located on opposite sides of the clearance portion 121, respectively. Specifically, the first part is located on the first side of the clearance portion 121 and the second part is located on the second side of the clearance portion 121. When the first part includes multiple connecting portions, the multiple connecting portions in the first part are arranged at intervals on the first side of the clearance portion 121; when the second part includes multiple connecting portions, the multiple connecting portions in the second part are arranged at intervals on the second side of the clearance portion 121. When each of the first part and the second part includes only one connecting portion, the connecting portions of the first part and the connecting portions of the second part are arranged facing each other relative to the clearance portion 121 to ensure the installation stability of the controller 1000 when fixedly installed using connecting portions. When one of the first part and the second part has one connecting portion and the other has multiple connecting portions, all connecting portions form a triangular arrangement to ensure the stability of the controller 1000 when fixedly installed using connecting portions.

[0100] Referring to Figures 11 and 12, in some embodiments of this application, two connecting portions 200 and 200A are provided on the first side of the clearance portion 121, and one connecting portion 200B is provided on the second side of the clearance portion 121. These three connecting portions 200 / 200A / 200B form a triangular arrangement. Referring to Figure 14, in some embodiments of this application, when the connecting portion 200 is installed on the back of the housing 100, a locking portion 210 is formed at the end of the connecting portion 200 near the clearance portion 121, and a through portion 220 is formed at the end away from the clearance portion 121. In some embodiments of this application, the connecting portion 200 can switch between a first position and a second position. The sliding direction of the connecting portion 200 when switching from the first position to the second position is called the first direction (the dotted-line arrow shown in Figure 12), and the sliding direction of the connecting portion 200 when switching from the second position to the first position is called the second direction (the dashed-line arrow shown in Figure 12).

[0101] Referring to Figures 11 and 12, when the connecting portion 200 is in the first position, the engaging portion 210 extends into the abutment portion 121, and the engaging portion 210 of the connecting portion 200 engages with the first flange 2200 of the guide rail 2000. Similarly, for the lower connecting portion, the corresponding engaging portion engages with the second flange 2300 of the guide rail 2000. At this time, the through portion 220 is at least partially covered by the housing 100, i.e., the through portion 220 is not completely exposed, as shown in Figures 11 and 12. In some embodiments of this application, when the engaging portion 210 extends into the abutment portion 121, a first gap is formed between the engaging portion 210 of the connecting portion 200, the bottom wall 1211 of the abutment portion 121, and its upper side wall 1212 for engaging the first flange 2200 of the guide rail 200. Similarly, a second gap is formed between the engaging portion of the lower connecting portion, the bottom wall 1211 of the clearance portion 121 and its lower side wall 1213 for engaging the second flange 2300 of the guide rail 2000, thereby enabling the controller 1000 to be mounted on the guide rail 2000 (see FIG11). When the connecting portions 200 / 200A / 200B switch from the first position to the second position, the engaging portion 210 moves away from the clearance portion 121 in the first direction, the engaging portion 210 of the upper connecting portion 200 / 200A releases the first flange 2200 of the guide rail 2000 and the engaging portion of the lower connecting portion 200B releases the second flange 2300 of the guide rail 2000, and the guide rail 2000 can be removed from the clearance portion 121. At this time, the through portion 220 extends beyond the housing 100 to expose the through portion 220 (see FIG13), that is, the through portion 220 can be fully seen from the front 111 of the housing 100. In some embodiments of this application, the controller 1000 can be fixedly mounted to the wall when the guide rail 2000 is removed from the clearance part 121.

[0102] As described above, after the guide rail 2000 can be removed from the clearance portion 121 when all connecting portions 200 / 200A / 200B are in the second position, at least one upper connecting portion of the upper connecting portions 200 / 200A and at least one lower connecting portion of the lower connecting portions 200B can be kept in the second position. Thus, multiple third fasteners are used to pass through the through portions 220 of at least one upper connecting portion and at least one lower connecting portion, respectively, and are fixed to the wall. Unused remaining connecting portions can be switched from the second position to the first position to ensure the appearance of the controller 1000, or, for the sake of simplifying operation, the unused remaining connecting portions can be kept in the second position. In some embodiments of this application, the third fastener can be a screw or an unthreaded nail.

[0103] In some embodiments of this application, when fixing the controller 1000, one upper connecting part and one lower connecting part directly opposite the upper connecting part can be used to ensure stable installation of the controller 1000 with a small number of fasteners. In some embodiments of this application, when fixing the controller 1000, one upper connecting part and two lower connecting parts can be used, forming a triangle to ensure triangular stability of the controller 1000. In some embodiments of this application, when the guide rail 2000 is removed from the clearance part 121, the controller 1000 can be wall-mounted through the wall-mounting holes 123 / 123A or wall-mounted using the through-parts 220 of the connecting parts 200 / 200A / 200B. In some embodiments of this application, after the guide rail 2000 can be removed from the clearance part 121 when all connecting parts 200 / 200A / 200B are in the second position, all connecting parts 200 / 200A / 200B can be switched to the first position. Thus, the controller 1000 is hung on the first fastener fixed to the wall through the wall-mounting holes 123 / 123A. In the above embodiments, by cooperating with the first fastener through the two wall-mounting holes 123 / 123A, the controller 1000 is suspended on the first fastener, preventing the controller 1000 from swaying left and right, thereby stably suspending the controller 1000 on the wall.

[0104] In some embodiments of this application, after the guide rail 2000 can be removed from the clearance portion 121 when all connecting portions 200 / 200A / 200B are in the second position, at least one connecting portion (e.g., connecting portion 200A) can be selected to be in the second position while the remaining connecting portions are switched to the first position. Thus, the controller 1000 is fixed to the wall using a combination of suspension and fixing, with the first fasteners mounted on the wall through the wall-mounting holes 123 / 123A, and at least one second fastener passing through the through portion of the selected at least one connecting portion 200A. The selected connecting portion 200A forms a triangle with the two wall-mounting holes 123 / 123A to stably fix the controller 1000. Alternatively, the two selected connecting portions can be the two lower connecting portions (not shown) located in the lower connecting portion, thereby preventing the controller 1000 from swaying left and right. In some embodiments of this application, the number of wall mounting holes 123 / 123A and connecting parts 200 / 200A / 200B can be flexibly set to adapt to different installation environments. For example, there may be one wall mounting hole 123 / 123A and two connecting parts 200 / 200A / 200B (one upper connecting part 200 / 200A and one lower connecting part 200B).

[0105] In some embodiments of this application, to enable the switching of the connecting parts 200 / 200A / 200B between the first and second positions, referring to FIG14, the controller 1000 further includes multiple guide parts 122 / 122A / 122B, the number of which is consistent with the number of the multiple connecting parts 200 / 200A / 200B. That is, one connecting part 200 / 200A / 200B slides within one guide part 122 / 122A / 122B, realizing the switching from the first position to the second position along the first direction, and the switching from the second position to the first position along the second direction. In some embodiments of this application, the controller 1000 or the expansion module 1000' is provided with an indicator light unit (not shown) for issuing instructions to the user, for example, when the air conditioning system is started, the indicator light in the indicator light unit corresponding to the air conditioning system lights up. The main control board 170 of the controller 1000 is disposed within the housing 100, and the corresponding indicator light unit is disposed on the main control board 170. Therefore, if the light emitted by each indicator light in the indicator light unit is to be guided out, a light guide component 180 is required. Different controllers 1000 or expansion modules 1000' with different functions require different numbers of indicator lights. Therefore, in order to avoid the problem of high cost caused by the need for independent design of different controllers 1000 or expansion modules 1000' due to different numbers of indicator lights during design and production, in some embodiments of this application, referring to Figures 15 and 16, a decorative plate 150 that cooperates with the light guide component 180 can be provided.

[0106] Referring to Figure 15, the decorative panel 150 is detachably mounted to the housing 100. It has multiple display areas to guide the light emitted by the corresponding indicator lights to each display area and simultaneously limit the movement of the light guide component 180. In some embodiments of this application, the decorative panel 150 on the controller 1000 is used as an example. The number of display areas on the decorative panel 150 varies, and the number of display areas can be designed to correspond to different numbers of indicator lights, depending on requirements. For example, when the main control board 170 of the controller 1000 has six indicator lights, the decorative panel 150 has display areas corresponding to the six indicator lights. When the main control board of an expansion module has three indicator lights, the decorative panel has display areas corresponding to the three indicator lights. When the main control board 170 of the controller 1000 has six indicator lights but only needs to indicate three of them, a decorative panel 150 with three display areas can be used. The specific decorative panel 150 can be selected as needed.

[0107] In some embodiments of this application, referring to FIG16, the light guide assembly 180 may include a light guide limiting portion and a light guide post 181, wherein the light guide post 181 is disposed on the light guide limiting portion. In some embodiments of this application, a light guide recess 111 is provided on the outer side of the front of the upper housing 110, and a plurality of cylindrical portions 114 (see FIG18) are formed on the inner sidewall of the upper housing 110 corresponding to the outer sidewall to accommodate the light guide post 181, the cylindrical portions 114 communicating with the light guide recess 111. The light guide limiting portion and the light guide recess 111 cooperate, and the light guide post 181 extends through the corresponding cylindrical portion 114 and faces the indicator light on the main control board 170. In some embodiments of this application, the number of light guide posts 181 may be the same as the number of indicator lights on the main control board 170, depending on the indication requirements.

[0108] In some embodiments of this application, referring to FIG15, a third snap-fit ​​structure is provided to make the decorative panel 150 detachable, thereby enabling the detachment of the decorative panel 150 from the front of the upper housing 110 via a snap-fit ​​mechanism. In some embodiments of this application, an insertion position (an insertion position 115 is shown in FIG16) is provided on the front of the upper housing 110. A first buckle (not shown) is provided on the inner side of the upper housing 110 corresponding to the insertion position 115, and a second buckle 152 is provided on the decorative panel 150 corresponding to the position of the first buckle. The first buckle and the second buckle 152 engage in a snap-fit ​​relationship. In some embodiments, the insertion position 115 is an insertion groove. When the decorative panel 150 is snapped onto the front of the upper housing 110, the decorative panel 150 abuts against the light guide limiting part, thereby limiting the light guide assembly 180 and preventing it from coming out of the light guide recess 111. The free end of the light guide post 181 away from the indicator light extends into the display area.

[0109] In some embodiments of this application, referring to FIG16, the light guide limiting portion includes a light guide limiting seat 182 and at least one limiting rib 183 protruding from the light guide limiting seat 182. The light guide limiting seat 182 is placed within the light guide recess 111, and the limiting rib 183 protrudes towards the free end of the light guide post 181 away from the indicator light. When the decorative panel 150 is snapped onto the front of the upper housing 110, the inner side of the decorative panel 150 abuts against the protruding surface of the limiting rib 183, thereby limiting the light guide assembly 180 and preventing it from dislodging from the light guide recess 111. The free end of the light guide post 181 away from the indicator light extends into the display area. In some embodiments of this application, referring back to FIG15, the display area includes a display grid hole 151, which is formed on the decorative panel 150. In some embodiments of this application, in order to avoid external dust from contaminating the light guide column 181, transparent windows (not shown) can be provided at each display grid hole 151 of the decorative panel 150.

[0110] In some embodiments of this application, referring to Figures 17 and 18, the grid holes 151 gradually taper from the inner sidewall to the outer sidewall of the decorative panel 150, serving as a guide for the installation of the decorative panel 150, facilitating its installation onto the upper housing 110, and preventing the decorative panel 150 from bumping against the free end of the light guide post 181 away from the indicator light during installation. In some embodiments of this application, referring to Figure 16, to facilitate the arrangement of the light guide assembly 180, the light guide recesses 111 described above can be configured as multiple spaced light guide recesses 111, with multiple cylindrical portions 114 provided on the inner sidewall of the front of the upper housing 110 corresponding to each light guide recess 111; multiple light guide assemblies 180 are also provided for each of the multiple light guide recesses 111, with one light guide assembly 180 provided on each light guide recess 111.

[0111] In some embodiments of this application, referring to Figures 15 and 18, the decorative panel 150 includes a first side panel 155 and a second side panel 156 that abuts against the first side panel 155 at an obtuse angle. The first side panel 155 has a display grid hole 151 as described above. In some embodiments of this application, to facilitate the installation of the decorative panel 150, a first receiving groove (not shown) is provided at the first connection position where the first side panel 155 connects to the upper housing 110, and a second receiving groove (not shown) is provided at the second connection position where the second side panel 156 connects to the upper housing 110. Correspondingly, still referring to Figure 15, a first protrusion 153 is provided on the first side panel 155 corresponding to the first receiving groove; the number of first protrusions 153 can be one or multiple spaced protrusions. A second protrusion 154 is provided on the second side panel 156 corresponding to the second receiving groove; the number of second protrusions 154 can be one or multiple spaced protrusions. When installing the decorative panel 150, the first protrusion 153 can be inserted into the first receiving groove first, and then downward force can be applied. Simultaneously, as the first and second latches 152 engage, the second protrusion 154 engages in the second receiving groove, completing the installation of the decorative panel 150. In some embodiments of this application, the decorative panel 150 itself is generally not allowed to be disassembled. Therefore, when disassembling the decorative panel 150, the connection between the upper housing 110 and the lower housing 120 should be disassembled first, and then manual force should be applied to disengage the first and second latches 152. Finally, the decorative panel 150 can be removed. In some embodiments of this application, other text, symbols, or patterns can also be provided on the decorative panel 150. The detachable decorative panel 150 allows for the convenient installation of different numbers of display areas according to the display requirements of the number of indicator lights on the controller 1000 or expansion module. At the same time, it can limit the position of the light guide column 181, which facilitates the installation of the light guide column 181 and prevents the light guide column 181 from falling out of the light guide recess 111 of the housing 100.
