[0086] 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.

[0087] 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.

[0088] See Figures 1 to 14 In some embodiments of this application, a controller 1000 is proposed, which includes a housing 100 and a main control board 170 (see...). Figure 1 ).

[0089] The housing 100 forms the exterior of the controller 1000, and the interior of the housing 100 forms a receiving space (not shown), in which the main control board 170 is disposed.

[0090] 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 can be flipped and connected to the upper housing 110 by pivoting and snap-fit / magnetic attraction and covers / exposes the maintenance opening.

[0091] During maintenance, the maintenance personnel flip the maintenance cover 190 to expose the maintenance port and perform maintenance or repair operations on the electrical components in the receiving space through the maintenance port, such as resetting, copying data, etc. After the maintenance is completed, the maintenance cover 190 is flipped to cover the maintenance port.

[0092] In some embodiments of this application, the controller 1000 may be mounted on either the guide rail 2000 or the wall.

[0093] It should be noted that the wall can be a vertical wall or an inclined wall. The guide rail 2000 can be pasted onto the wall or fixed to the wall with threaded parts.

[0094] In some embodiments of this application, for the convenience of wall mounting and rail mounting of the controller 1000, see [link to relevant documentation]. Figure 2 and Figure 3 The back of the housing 100 is provided with wall mounting holes 123 / 123A and a clearance part 121 for the guide rail 2000, and the guide rail 2000 is accommodated in the clearance part 121.

[0095] When housing 100 includes upper housing 110 and lower housing 120, the back side of housing 100 refers to the back side of lower housing 120.

[0096] 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 the front is the back of the housing 100.

[0097] In some embodiments of this application, for ease of description, the avoidance portion 121 is along... Figure 2 The solid arrow shown indicates the length extension direction of the avoidance part 121, denoted as left and right extension. The first side of the avoidance part 121 is the upper side and the second side of the avoidance part 121 is the lower side.

[0098] See 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.

[0099] See Figure 3 The corresponding guide rail 2000 has a middle U-shaped part 2100 and a first flange 2200 and a second flange 2300 located on both sides of the middle U-shaped part 2100. The first flange 2200 and the second flange 2300 both extend away from the middle U-shaped part 2100.

[0100] In some embodiments of this application, see reference 1. Figure 2 The controller 1000 also includes a clamping portion and at least one fixing portion 125 formed on the housing 100, both of which are formed on the back side of the lower housing 120.

[0101] In some embodiments of this application, the fixing part 125 and the clamping part are integrally formed with the lower housing 120.

[0102] In some embodiments of this application, see Figure 2 and Figure 3 The clamping part may include a locking protrusion 124, which is disposed on the upper side wall 1212 of the clearance part 121 and protrudes toward the lower side wall 1213 of the clearance part 121, so that a first gap (not marked) is formed between the locking protrusion 124, the upper side wall 1212 and the bottom wall 1211 of the clearance part 121, for engaging the first flange 2200 of the guide rail.

[0103] 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.

[0104] In some embodiments of this application, the back side of the fixing part 125 has a mounting part 1252 and the portion extending beyond the housing 100 has a through part 1251.

[0105] 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 fixed part 125 via the mounting part 1252.

[0106] When the deformable part 130 is installed to the corresponding mounting part 1252, the end of the deformable part 130 near the relief part 121 forms a locking part 132 that extends into the relief part 121, so that a second gap (not marked) is formed between the locking part 132 of the deformable part 130, the bottom wall 1211 of the relief part 121 and its lower side wall 1213, for locking the second flange 2300 of the guide rail 2000.

[0107] The at least one fixing part 125 described above can be divided into the following two cases.

[0108] 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. Note that the plurality of latching protrusions 124 are spaced apart along the length direction 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.

[0109] The first fixing part 1252 is fitted with a deformation part 130, which is referred to as the first deformation part.

[0110] When the controller 1000 is assembled using the guide rail, multiple locking 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.

[0111] When fastening the installation to the wall, the first fastener passes through the through-hole 1251 of the first fixing part and is fixed to the wall.

[0112] When wall-mounting, the second fastener, which is fixed to the wall using wall mounting holes 123 / 123A, is used to achieve wall mounting.

[0113] In some embodiments of this application, the wall mounting hole 123 / 123A can be a closed hole or an open hole on the lower side.

[0114] In some embodiments of this application, for ease of mounting, the wall mounting hole 123 / 123A is configured as an open hole on the bottom, see [reference]. Figure 2 The wall mounting hole 123 / 123A extends upward from the upper side wall 1212 of the clearance part 121 and communicates with the clearance part 121. When the controller 1000 is mounted, the second fastener is more easily inserted into the wall mounting hole 123 / 123A through the lower part that communicates with the clearance part 121.

[0115] In some embodiments of this application, see 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 directions of the clearance part 121.

[0116] In some embodiments of this application, in order to enhance the stability of the controller 1000 wall-mounted installation, when using the wall mounting hole 123 / 123A for wall mounting, a third fastener is used to pass through the through portion 1251 of the first fixing part, so as to fix the controller 1000 to the wall surface by a combination of suspension and fixing.

[0117] In some embodiments of this application, see Figure 2 The fixing part 125 and the two wall mounting holes 123 / 123A form a triangle to achieve stable fixing of the controller 1000.

[0118] In some embodiments of this application, the number of wall mounting holes 123 / 123A can be flexibly set.

[0119] The first, second, and third fasteners can be screws or unthreaded nails.

[0120] In some embodiments of this application, when multiple fixing portions 125 exist, the multiple latching protrusions 124 and some of the fixing portions 125 (denoted as at least one first fixing portion) are arranged opposite to each other on both sides of the clearance portion 121. Specifically, the multiple latching protrusions 124 are arranged on the first side of the clearance portion 121, and at least one first fixing portion is arranged on the second side of the clearance portion 121. The remaining fixing portions 125 may 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 portion 121.

[0121] Each first fixing part has a deformation part 130 installed in its mounting part 1252, referred to as the first deformation part.

[0122] When the controller 1000 is assembled using the guide rail, multiple locking 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.

[0123] During wall fastening, a first fastener is used to pass through the through-hole of the first fixing part, and / or a second fastener is used to pass through the through-hole 1251 of at least one of the remaining fixing parts 125 to fix it to the wall.

[0124] In some embodiments of this application, in order to enhance the stability of the controller 1000 wall-mounted installation, when using the wall-mounting hole 123 / 123A for wall mounting, a fourth fastener is used to pass through the through portion 1251 of at least one first fixing part and / or the through portion 1251 of at least one of the remaining fixing parts 125, so as to fix the controller 1000 to the wall surface by a combination of suspension and fixing.

[0125] In some embodiments of this application, the fixing part 125 and the clamping part may be integrally formed with the lower housing 120.

[0126] In some embodiments of this application, at least one deformable part is installed in the mounting portion 1252 of at least one fixed part located on a different side from the clamping part 121.

[0127] 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 embedded in the first limiting recess 1253, thus achieving installation in place.

[0128] 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.

[0129] In some embodiments of this application, both the deformable portion 130 and the first limiting protrusion are made of deformable material.

[0130] In some embodiments of this application, the deformable portion 130 and the first limiting protrusion are integrally formed.

[0131] 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.

[0132] In some embodiments of this application, see Figure 4 In order to facilitate the guide rail 2000 to be engaged with the clearance part 121, the side of the engaging part 132 of the deformable part 130 away from the clearance part 121 forms a guide surface 133. The guide surface 133 is inclined towards the clearance part 121 for guidance. When the user applies external force to the side where the second flange 2300 of the guide rail 2000 is located, it is guided by the guide surface 133 to facilitate the guide rail 2000 to be engaged in the engaging part 132.

[0133] In some embodiments of this application, the limiting protrusion 1343 is formed in a cantilever form to facilitate the deformation of the easily deformable part 130.

[0134] See Figure 4 and Figure 5 The deformable part 130 has a deformable cantilever 134 and a through hole 135. The deformable cantilever 134 is disposed in the through hole 135 to provide deformation space for the deformable cantilever 134.

[0135] In some embodiments of this application, the deformable cantilever 134 includes a connecting arm 1341 and a limiting arm 1342. The end of the connecting arm 1341 that is 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 that extends out of the deformable part 130 and faces the bottom plane of the mounting part 1252 forms the limiting protrusion 1343.

[0136] The through hole 135 and the deformation cantilever 134 increase the elastic deformation force of the deformation part 130, so that when an external force is applied to the guide rail 2000, only a small external force is needed to deform the deformation part 130 and insert the second flange 2300 of the guide rail 2000 into the locking part 132.

[0137] Furthermore, the through hole 135 and the deformation cantilever 134 not only ensure that the deformation part 130 is easy to deform, but also reduce the thickness of the deformation part 130 in the length direction perpendicular to the mounting part 1252, thereby reducing cost and reducing the overall volume of the controller 1000.

[0138] In some embodiments of this application, the deformable part 130 is slidably installed into the mounting part 1252 by means of a sliding fit.

[0139] In some embodiments of this application, see Figure 4 The mounting portion 1252 extends through the deformation portion 130 in the sliding direction. When the deformation portion 130 is installed into the mounting portion 1252, the locking portion 132 extends out from the end of the mounting portion 1252 that is close to the clearance portion 121 (referred to as the first end) and extends into the clearance portion 121. The end of the mounting portion 1252 that is opposite to the first end and away from the clearance portion 121 (referred to as the second end) is the mounting opening 1255 of the mounting portion 1252.

[0140] In some embodiments of this application, a slider 1254 is formed on the inner sidewall of the mounting portion 1252 of the fixing portion 125, and correspondingly, slide rails 131 that cooperate with the slider 1254 are formed on both sides of the deformable portion 130.

[0141] 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.

[0142] In some embodiments of this application, see Figure 5 The free end of the limiting protrusion 1343 forms an inclined limiting guide surface 1344 at the front end of the sliding direction of the deformed part 130, and the limiting guide surface 1344 forms an acute angle with the bottom wall 1211 of the mounting part 1252.

[0143] When the deformable part 130 extends into the mounting opening 1255 of the mounting part 1252 and slides within the mounting part 1252, the limiting guide surface 1344 reduces the friction between the deformable part 130 and the bottom wall 1211 of the mounting part 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 part 1252.

[0144] 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.

[0145] In some embodiments of this application, the free end of the limiting protrusion 1343 may form an inclined limiting guide surface 1344 at the front end along the sliding direction of the deformed portion 130, and see also Figure 4 An avoidance notch is formed at the mounting opening 1255 of the mounting part 1252 to avoid the limiting protrusion 1343. The avoidance notch forms an inclined guide surface that matches the limiting guide surface 1344, so that the limiting protrusion 1343 can slide into the mounting part 1252.

[0146] Furthermore, the cooperation between the limiting guide surface 1344 and the clearance notch also helps to achieve accurate positioning of the deformable part 130.

[0147] In some embodiments of this application, the deformable part 130 is an independent component that can be mass-produced. When in use, the number of deformable parts 130 can be selected according to the number of fixing parts 125 on the housing 100 that correspond to the clamping part.

[0148] In use, each deformable part 130 is installed into each 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 to complete 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. The external force causes each deformable part 130 to deform, so that the second flange 2300 is snapped into the second gap formed by the clamping part 132 and the clearance part 121 to complete the snap-fit ​​of the second flange 2300. At the same time, the deformable part 130 completes the deformation recovery, and the elastic recovery force also applies force to the guide rail 2000 to ensure that the guide rail 2000 is stably located in the clearance part 121.

[0149] 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.

[0150] See Figure 6 The first snap-fit ​​structure includes a snap-fit ​​and a snap-fit ​​groove. The snap-fit ​​groove can be set on the upper housing 110, and the corresponding snap-fit ​​can be set on the lower housing 120, or the snap-fit ​​groove can be set on the lower housing 120, and the corresponding snap-fit ​​can be set on the upper housing 110.

[0151] In some embodiments of this application, the upper housing 110 is provided with a plurality of lifting lugs 112 at circumferential intervals, and each lifting lug 112 has a slot. Correspondingly, buckles 126 are provided at corresponding circumferential positions 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, thereby achieving a snap-fit ​​connection between the upper housing 110 and the lower housing 120.

[0152] 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.

[0153] The first clearance opening can be provided on the upper housing 110 or on the lower housing 120.

[0154] In some embodiments of this application, see Figure 6 The housing 100 of the controller 1000 has a square design, and multiple first snap-fit ​​structures are set at the four corners of the upper housing 110 and the lower housing 120.

[0155] To prevent the upper housing 110 and the lower housing 120 from warping at the connection point, a plurality of second snap-fit ​​structures are provided at the connection point. These second snap-fit ​​structures can be located between two adjacent first snap-fit ​​structures on one side of the clearance portion 121.

[0156] In some embodiments of this application, the second snap-fit ​​structure includes a snap fastener and a snap slot. The snap slot can be disposed on the upper housing 110, and the corresponding snap fastener can be disposed on the lower housing 120, or the snap slot can be disposed on the lower housing 120, and the corresponding snap fastener can be disposed on the upper housing 110.

[0157] 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.

[0158] In some embodiments of this application, for ease of wiring, see [reference needed]. Figure 1 As described above, the wiring terminals are located on one or both sides of the clearance section 121, and the number can be flexibly set according to the wiring requirements.

[0159] This terminal block can be used for signal (e.g., communication signals, control signals) transmission, power supply, etc. A terminal block used for transmitting communication signals is called a communication terminal block, for example, communication terminal block 140.

[0160] 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 [link to relevant documentation]). Figure 7 For example, in the case of four expansion modules, the first expansion module is used to output signals to control the air conditioning system, the second expansion module is used to output signals to control the hot water system, the third expansion module is used to output signals to control the lighting system, and the fourth expansion module is used to output signals to control the elevator system.

[0161] 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.

[0162] 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 realize either rail mounting or wall mounting.

[0163] In some embodiments of this application, to meet the connection requirements of the controller 1000 and the expansion module under various installation conditions (e.g., rail mounting, wall mounting), see [link to relevant documentation]. Figures 7 to 9 In addition to the communication terminals as described above, an expansion adapter 3000 for expansion is also provided.

[0164] Using this expansion adapter 3000, it is possible to connect the controller 1000 mounted on the same guide rail 2000 to an adjacent expansion module, such as expansion module 1000', or to connect two adjacent expansion modules mounted on the same guide rail 2000.

[0165] In some embodiments of this application, the housing 100 of the controller 1000 forms two second clearance openings for the clearance extension adapter 3000 at both ends of the clearance portion 121 in the length extension direction (see...). Figure 8 (This shows a second clearance opening 160 on the right side).

[0166] 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 in the length extension direction to clearance the expansion adapter portion 3000 (see...). Figure 7 It shows a third clearance opening 160' on the right.

[0167] In some embodiments of this application, as described above, the upper housing 110 and lower housing 120 of the controller 1000 respectively form the second clearance opening 160 at the connection position in the length extension direction of the clearance portion 121. The second clearance opening 160 may be provided on the upper housing 110 of the controller 1000, or on the lower housing 120 of the controller 1000, or it may be partially provided on the upper housing 110 of the controller 1000 and partially provided on the lower housing 120 of the controller 1000.

[0168] In some embodiments of this application, the upper housing and lower housing of the expansion module 1000' respectively form the third clearance opening at the connection position in the length extension direction of their clearance portion. The third clearance opening can be provided on the upper housing of the expansion module or on the lower housing of the expansion module.

[0169] See 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 expansion module 1000' adjacent to the controller 1000, respectively, thereby realizing the expansion connection between the controller 1000 and the adjacent expansion module 1000'.

[0170] Another expansion adapter 3000 connects to the main control board of the two adjacent expansion modules through a third clearance opening on one expansion module and a third clearance opening on another adjacent expansion module, thereby realizing the expansion connection between the adjacent expansion modules.

[0171] In some embodiments of this application, the structure of the expansion adapter 3000 is described as an example of the expansion adapter 3000 that connects the main control board 170 of the adjacent controller 1000 and the main control board 170' of the expansion module 1000'.

[0172] See Figure 9 and Figure 10 The extension adapter 3000 includes a first extension port 3100 and a second extension port 3200 arranged opposite to the first extension port 3100. The first extension port 3100 and the second extension port 3200 are located on the same straight line and the straight line is parallel to the length extension direction of the avoidance part 121. The opening directions of the first extension port 3100 and the second extension port 3200 are opposite to each other and are electrically connected to each other.

[0173] 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'.

[0174] In some embodiments of this application, the first expansion port 3100 and the second expansion port 3200 achieve simultaneous clamping and electrical connection to the corresponding main control board by clamping the corresponding main control board.

[0175] In some embodiments of this application, see Figure 10 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 contact points on the first clamping part 3112 are electrically connected to the communication points on a portion of the main control board 170 and clamp the main control board 170.

[0176] The second expansion port 3200 includes a second locking part (not marked). Another portion of the main control board 170' of the expansion module 1000', which has a communication point, extends into the second expansion port 3200. The electrical contact point on the second locking part is used to electrically connect to the communication point of the expansion module 1000' and to lock the main control board 170' of the expansion module 1000'.

[0177] In some embodiments of this application, see Figure 10 The first expansion port 3100 also includes a first insertion part 3111 and a first receiving part 3113, wherein the first insertion part 3111, the first locking part 3112 and the first receiving part 3113 are connected in sequence from their opening (referred to as the first opening).

[0178] For example, a portion of the main control board 170 of the controller 1000 with communication points can be inserted through the first opening and then extended into the first receiving portion 3113 through the first insertion portion 3111, so that the communication points are electrically connected to the electrical contact points of the first locking portion 3112 and locked at the same time.

[0179] In some embodiments of this application, see Figure 10 The first clamping part 3112 is located between the first receiving part 3113 and the first insertion part 3111. It gradually narrows from the first insertion part 3111 to the first clamping part 3112 and gradually widens from the first clamping part 3112 to the first receiving part 3113. In this way, the first clamping part 3112 can clamp the main control board 170 while realizing the electrical connection with the communication point.

[0180] 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.

[0181] In some embodiments of this application, see Figure 7 and Figure 9 When the controller 1000 and multiple expansion modules (e.g., expansion module 1000') are sequentially installed 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.

[0182] In use, the controller 1000 can be installed 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' can be installed on the guide rail 2000. The expansion module 1000' can be moved on the guide rail 2000 so that the second expansion port 3200 of the expansion adapter 3000 can be connected to the main control board 170' of the expansion module 1000'.

[0183] 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.

[0184] In some embodiments of this application, when the 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 to each other via corresponding communication terminals 140.

[0185] In some embodiments of this application, when the installation space is limited and the controller 1000 can only be mounted on a rail, the expansion module not mounted on the rail is connected to the controller 1000 or its adjacent expansion module via the communication terminals thereon.

[0186] In some embodiments of this application, when the installation space is limited and only the controller 1000 and some expansion modules can be mounted on the rail, the expansion modules not mounted on the rail are connected to the adjacent expansion modules via communication terminals.

[0187] The communication terminal block 140 and the expansion adapter 3000 can meet the expansion needs of the controller 1000 under different installation conditions, providing users with a flexible expansion connection solution.

[0188] In some embodiments of this application, an indicator light unit (not shown) is provided on the controller 1000 or the expansion module 1000' to give 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 is lit.

[0189] The main control board 170 of the controller 1000 is located within the housing 100, and the corresponding indicator light unit is located on the main control board 170. Therefore, if you want to draw out the light emitted by each indicator light in the indicator light unit, you need to set up a light guide component 180.

[0190] Different controllers 1000 or expansion modules 1000' require different numbers of indicator lights. Therefore, to avoid the problem of high costs 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, some embodiments of this application refer to... Figure 11 and Figure 12 A decorative panel 150 can be provided to cooperate with the light guide assembly 180.

[0191] See Figure 11 The decorative panel 150 can be detachably installed onto the housing 100. It has multiple display areas, which are used to guide the light emitted by the corresponding indicator lights to each display area, and at the same time limit the light guide component 180.

[0192] In some embodiments of this application, the decorative panel 150 on the controller 1000 is used as an example for illustration.

[0193] The number of display areas on the decorative panel 150 varies, and the number of display areas corresponding to different numbers of indicator lights can be designed according to requirements. For example, when the main control board 170 of the controller 1000 is equipped with six indicator lights, the decorative panel 150 is equipped with display areas corresponding to the six indicator lights. When the main control board of an expansion module is equipped with three indicator lights, the decorative panel is equipped with display areas corresponding to the three indicator lights. When the main control board 170 of the controller 1000 is equipped with six indicator lights and only three indicator lights need to be indicated, the decorative panel 150 with three display areas can be used. The specific decorative panel 150 can be selected according to the needs.

[0194] In some embodiments of this application, see Figure 12 The light guide assembly 180 may include a light guide limiting part and a light guide post 181, wherein the light guide post 181 is disposed on the light guide limiting part.

[0195] In some embodiments of this application, a light-guiding recess 111 is provided on the outer side of the front of the upper housing 110, and a plurality of cylindrical portions 114 for accommodating the light guide post 181 are formed on the inner sidewall of the upper housing 110 corresponding to the outer side (see...). Figure 14 The cylindrical portion 114 is connected to the light guide recess 111.

[0196] The light guide limiting part and the light guide recess 111 cooperate, and the light guide post 181 extends through the corresponding cylindrical part 114 and is directly opposite the indicator light on the main control board 170.

[0197] In some embodiments of this application, the number of light guide columns 181 may be the same as the number of indicator lights on the main control board 170, depending on the indication requirements.

[0198] In some embodiments of this application, see Figure 11 In order to make the decorative panel 150 removable, a third snap-fit ​​structure is provided, which enables the decorative panel 150 to be detached from the front of the upper housing 110 through snap-fit.

[0199] In some embodiments of this application, an insertion slot is formed on the front side of the upper housing 110. Figure 12 The upper housing 110 is provided with a first buckle (not shown) on the inner side of the insertion slot 115 corresponding to the insertion slot 115. The decorative panel 150 is provided with a second buckle 152 at the position corresponding to the first buckle. The first buckle and the second buckle 152 are engaged and cooperated.

[0200] 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 to limit the light guide component 180, preventing it from coming out of the light guide recess 111, and the free end of the light guide column 181 away from the indicator light extends into the display area.

[0201] In some embodiments of this application, see Figure 12 The light guide limiting part 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 in the light guide recess 111, and the limiting rib 183 protrudes toward the free end of the light guide column 181 away from the indicator light.

[0202] 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 surface of the protruding limiting rib 183, 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 column 181 away from the indicator light extends into the display area.

[0203] In some embodiments of this application, see reference 1. Figure 11 The display area includes a display grid hole 151, which is formed on the decorative panel 150.

[0204] 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.

[0205] In some embodiments of this application, see Figure 14 The display grid hole 151 gradually narrows from the inner side wall to the outer side wall of the decorative panel 150, which serves as a guide for the installation of the decorative panel 150, making it convenient to install the decorative panel 150 onto the upper housing 110, and preventing the decorative panel 150 from hitting the free end of the light guide post 181 away from the indicator light during installation.

[0206] In some embodiments of this application, see Figure 12 To facilitate the arrangement of the light guide components 180, the light guide recesses 111 described above can be configured as multiple spaced light guide recesses 111, and multiple cylindrical portions 114 are provided on the inner side wall of the front of the upper housing 110 for each light guide recess 111; multiple light guide components 180 are also provided for each of the multiple light guide recesses 111, and one light guide component 180 is provided on one light guide recess 111.

[0207] In some embodiments of this application, see Figure 11 and Figure 14 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 display grid holes 151 as described above.

[0208] In some embodiments of this application, in order to facilitate the installation of the positioning decorative panel 150, a first receiving groove (not shown) is provided at the first connection position where the upper housing 110 is connected to the first side plate 155 and the upper housing 110, and a second receiving groove (not shown) is provided at the second connection position where the upper housing 110 is connected to the second side plate 156 and the upper housing 110.

[0209] Correspondingly, see still Figure 11 A first protrusion 153 is provided on the first side plate 155 corresponding to the first receiving groove. The number of the first protrusion 153 can be one or multiple spaced protrusions. A second protrusion 154 is provided on the second side plate 156 corresponding to the second receiving groove. The number of the second protrusion 154 can be one or multiple spaced protrusions.

[0210] When installing the decorative panel 150, the first protrusion 153 can be embedded into the first receiving groove first, and then downward force can be applied. At the same time that the first buckle and the second buckle 152 are engaged, the second protrusion 154 is embedded into the second receiving groove, thus completing the installation of the decorative panel 150.

[0211] In some embodiments of this application, the decorative panel 150 itself is 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 the first and second clips 152 should be disengaged by manual force, and finally the decorative panel 150 should be removed.

[0212] In some embodiments of this application, other text, logos, or patterns may also be provided on the decorative panel 150.

[0213] 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.
