Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a controller component. Background Technology

[0002] In the new generation of intelligent device control systems, controllers are typically mounted on walls for user operation. Due to varying installation environments, most controllers use communication cables for functional expansion. This leads to messy wiring as more functions are added, making it difficult to find the corresponding connection cables during maintenance. Furthermore, when expanding to multiple modules, each communication cable needs to be manually connected, resulting in a large workload, low efficiency, and the risk of incorrect wiring. Utility Model Content

[0003] In response to the problems pointed out in the background art, some embodiments of this application relate to a controller assembly that enables flexible installation of the controller, including rail mounting and wall mounting. Furthermore, through an extension adapter and communication terminals, it enables extended connections between the controller and external expansion modules under different installation methods, thereby improving the flexibility of controller expansion connections.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0005] Embodiments of this application provide a controller component, which includes:

[0006] A controller, suitable for installation on either a guide rail or a wall, and comprising:

[0007] The housing has a clearance portion on its back side to avoid the guide rail, and clearance openings are formed at both ends of the clearance portion in the length extension direction of the housing.

[0008] The main control board is located inside the housing, and the communication points on the main control board are arranged on the part of the main control board near the side clearance openings.

[0009] A communication terminal block, which is electrically connected to the communication point of the main control board and is located outside the housing, is used to lead out the communication signal of the main control board;

[0010] An extension adapter has a first extension port and a second extension port that are electrically connected and have opposite opening directions. When the controller is installed on the guide rail, the first extension port extends into a side clearance opening and is electrically connected to a communication point on the main control board. The second extension port is used to electrically connect to a communication point of an external extension module installed on the guide rail.

[0011] Here, the surface facing the user after the controller is installed is defined as the front, and the surface opposite the front is defined as the back.

[0012] The embodiments involved in this application have the following advantages and beneficial effects:

[0013] When the controller is installed on the rail, an expansion adapter can be used to connect an external expansion module. The expansion module can also be expanded using the expansion adapter to connect an external expansion module, realizing multi-functional expansion of the controller and expansion module installed on the rail. No wiring or communication cable connection is required, saving time and effort.

[0014] When the controller cannot be installed on a rail due to limited space, a communication terminal block is used to achieve communication connection between the controller and the expansion module.

[0015] This allows for flexibility in connecting expansion modules to the controller under different installation methods.

[0016] In some embodiments of this application, the first expansion port and the second expansion port have the same structure, and the first expansion port includes:

[0017] The first clamping part has a portion of the main control board with communication points extending into the first expansion port. The electrical contact points on the first clamping part are electrically connected to the communication points on the portion of the main control board and clamp the main control board.

[0018] The second expansion port includes:

[0019] The second clamping part, another part of the main control board with communication points extends into the second expansion port, and the electrical contact points on the second clamping part are used to electrically connect the communication points of the external expansion module and clamp the main control board of the external expansion module.

[0020] The embodiments involved in this application have the following advantages and beneficial effects:

[0021] During connection, the first expansion port is used to connect to the communication point on the main control board of the controller while simultaneously securing the main control board. The second expansion port is used to connect to the communication point on the main control board of the external expansion module while simultaneously securing the main control board. The first and second expansion ports are electrically connected. Therefore, the controller and expansion module located on the guide rail are connected via the expansion adapter. This connection method is simple and easy to operate, and improves communication connection efficiency.

[0022] In some embodiments of this application, the first expansion port further includes:

[0023] A first insertion portion having the first opening;

[0024] A first receiving portion is connected to the first insertion portion, and the locking portion is located between the first receiving portion and the first insertion portion, gradually narrowing from the first insertion portion to the first locking portion and gradually widening from the first locking portion to the first receiving portion.

[0025] The embodiments involved in this application have the following advantages and beneficial effects:

[0026] The first insertion part facilitates the insertion of the main control board with communication points and makes contact with the first locking part, while the first receiving part provides clearance for this part of the main control board to avoid collision when the main control board is inserted into the first expansion port.

[0027] In some embodiments of this application, the controller further includes:

[0028] At least one fixing part is formed on the housing, a mounting part is provided on the back of the fixing part and a through part is formed on the portion extending beyond the housing, at least one of the at least one fixing parts is located on one side of the clearance part, and a first limiting recess is formed on the bottom wall of the mounting part;

[0029] A clamping part, which is arranged opposite to at least one fixing part located on one side of the clearance part;

[0030] At least one deformable part is provided thereon with a first limiting protrusion that is deformable and cooperates with the first limiting recess, and at least one deformable part is installed in the mounting part of at least one fixed part located on one side of the clearance part;

[0031] When the controller is installed on the guide rail, the deformable part deforms to apply an elastic force toward the guide rail, causing the guide rail to be pressed between the deformable part and the clamping part;

[0032] When the controller is installed on the wall, the housing is secured to the wall via a second fastener that passes through at least one fixing part.

[0033] The embodiments involved in this application have the following advantages and beneficial effects:

[0034] With the deformable deformation part, when the controller is installed on the guide rail, the first flange of the guide rail is clamped by the clamping part, and the second flange is deformed by the external force. The deformation part applies an elastic force towards the guide rail by the deformation part to clamp the second flange of the guide rail, thereby realizing the guide rail installation of the controller.

[0035] The fixing part has a through part that extends out of the housing, and the fixing part can be fixed to the wall by means of the fasteners of the through part.

[0036] The housing is fixed to the wall via wall mounting holes and fasteners, enabling the controller to be wall-mounted.

[0037] Furthermore, the housing can be combined with the through-hole of the fixing part and the wall mounting hole to achieve a more stable installation of the controller on the wall. In this way, three installation methods can be realized: controller rail installation, wall mounting, and wall fixed installation, which improves the flexibility of controller installation scenarios.

[0038] Furthermore, during rail mounting, users do not need to operate the deformable part; they only need to apply external force to it, making operation convenient and enabling easy rail mounting of the controller.

[0039] In some embodiments of this application, the clamping part includes:

[0040] A locking protrusion is provided on one side wall of the clearance portion and protrudes toward the other side wall of the clearance portion, so that a gap for locking the guide rail is formed between the locking protrusion, one side wall of the clearance portion and the bottom wall of the clearance portion.

[0041] The embodiments involved in this application have the following advantages and beneficial effects:

[0042] The clamping part includes a locking protrusion, which facilitates the pre-installation of the first flange of the guide rail onto the clearance part, providing accurate positioning for guide rail installation.

[0043] In some embodiments of this application, the end of the deformable portion near the avoidance portion forms a locking portion, which extends into the avoidance portion;

[0044] The side of the locking part away from the avoidance part forms a guide surface, and the guide surface is inclined towards the avoidance part for guidance.

[0045] The embodiments involved in this application have the following advantages and beneficial effects:

[0046] The guide surface formed by the locking part allows the second flange to be easily guided into the locking part when the user applies external force to the side where the second flange is located, improving the ease of installation. The guide surface also helps to reduce the applied external force, saving time and effort.

[0047] When the user applies external force to the side where the second flange is located, the deformation part deforms, so that the second flange is guided and locked into the locking part by the guide surface.

[0048] In some embodiments of this application, the deformable part is slidably mounted in the mounting part by means of a sliding fit;

[0049] The mounting portion extends through the sliding direction of the deformable portion, and the end of the mounting portion away from the clearance portion is a mounting opening through which the deformable portion slides into or out of the mounting portion.

[0050] An avoidance notch is formed at the mounting opening to avoid the free end of the first limiting protrusion.

[0051] The embodiments involved in this application have the following advantages and beneficial effects:

[0052] The sliding fit method facilitates the installation of the deformable part within the mounting section, improving installation convenience and saving time and effort.

[0053] The clearance notch helps the deformable part slide into or out of the mounting part through the mounting opening, and also helps in the positioning of the deformable part within the mounting part.

[0054] In some embodiments of this application, the free end of the first limiting protrusion forms a limiting guide surface at the front end along the sliding direction of the deformed part, and the limiting guide surface forms an acute angle with the bottom wall of the mounting part;

[0055] The clearance notch forms an inclined guide surface that matches the limiting guide surface.

[0056] The embodiments involved in this application have the following advantages and beneficial effects:

[0057] The limiting guide surface facilitates the reduction of friction between the deformable part and the bottom wall of the mounting base when the mounting part slides, and when the part is installed in place, the first limiting protrusion can be easily guided into the first limiting recess through the limiting guide surface.

[0058] In some embodiments of this application, the deformable portion has:

[0059] A deformable elastic arm includes a connecting arm and a limiting arm. One end of the connecting arm is fixedly connected to the deformable part, and the other end is suspended. The limiting arm is formed at the suspended end. The portion of the limiting arm that extends out of the deformable part and faces the bottom plane of the mounting part forms the first limiting protrusion.

[0060] A through hole, in which the deformable elastic arm is disposed.

[0061] The embodiments involved in this application have the following advantages and beneficial effects:

[0062] The deformation arm and through hole are designed to increase the elastic deformation capacity of the deformation part, so that when an external force is applied to the guide rail, only a small external force is needed to deform the deformation part and lock the second flange of the guide rail into the locking part.

[0063] Furthermore, the thickness of the deformable part in the direction perpendicular to the length of the mounting part (i.e., the sliding direction of the deformable part) has been reduced, thereby reducing cost and decreasing the overall size of the controller.

[0064] In some embodiments of this application, the controller further includes:

[0065] Multiple connecting portions are installed on the back of the housing and are spaced apart on both sides of the clearance portion along the extending direction of the clearance portion. Each connecting portion is provided with a through portion and can be switched between a first position and a second position.

[0066] When the controller is installed on the guide rail, the ends of multiple connecting parts in the first position and near the clearance part extend into the clearance part to engage with the first and second flanges of the guide rail.

[0067] When the controller is installed on the wall, at least one connecting part on one side of the clearance portion and at least one connecting part on the other side of the clearance portion are in the second position and are fixed to the wall via a third fastener passing through the corresponding through portion.

[0068] The embodiments involved in this application have the following advantages and beneficial effects:

[0069] With the switchable connection part, when the controller is installed on the guide rail, the first connection part is in the first position, and the connection part engages with the first flange and the second flange of the guide rail.

[0070] When the controller is wall-mounted, the guide rail is released by switching the connecting part to the second position. The housing is fixed to the first fastener on the wall through the wall-mounting hole, and the second fastener is fixed to the wall through the through part of at least one connecting part. At this time, the unused remaining connecting part can be in the first position.

[0071] When the controller is fixedly installed on the wall, the connecting part is switched to the second position to release the guide rail. The third fastener is fixed to the wall via the through part of at least one connecting part on one side of the clearance part and at least one connecting part on the other side. At this time, the unused remaining connecting parts can be in the first position.

[0072] This allows for three installation methods for the controller: rail mounting, wall mounting, and fixed mounting, improving the flexibility of controller installation scenarios.

[0103] 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.

[0104] 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.

[0105] See Figures 1 to 18 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 ).

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In some embodiments of this application, the controller 1000 may be mounted on either the guide rail 2000 or the wall.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] See Figure 3The 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.

[0117] 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. Referring to the figure, the clamping portion and at least one fixing portion 125 are both formed on the back side of the lower housing 120.

[0118] In some embodiments of this application, the fixing part 125 and the clamping part are integrally formed with the lower housing 120.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] The at least one fixing part 125 described above can be divided into the following two cases.

[0125] 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.

[0126] The first fixing part 1252 is fitted with a deformation part 130, which is referred to as the first deformation part.

[0127] 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.

[0128] 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.

[0129] When wall-mounting, the second fastener, which is fixed to the wall using wall mounting holes 123 / 123A, is used to achieve wall mounting.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] In some embodiments of this application, the number of wall mounting holes 123 / 123A can be flexibly set.

[0136] The first, second, and third fasteners can be screws or unthreaded nails.

[0137] 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.

[0138] Each first fixing part has a deformation part 130 installed in its mounting part 1252, referred to as the first deformation part.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] In some embodiments of this application, the fixing part 125 and the clamping part may be integrally formed with the lower housing 120.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] In some embodiments of this application, both the deformable portion 130 and the first limiting protrusion are made of deformable material.

[0147] In some embodiments of this application, the deformable portion 130 and the first limiting protrusion are integrally formed.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] In some embodiments of this application, the deformable part 130 is slidably installed into the mounting part 1252 by means of a sliding fit.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] Furthermore, the cooperation between the limiting guide surface 1344 and the clearance notch also helps to achieve accurate positioning of the deformable part 130.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] See Figure 6The 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.

[0168] 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.

[0169] 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.

[0170] The first clearance opening can be provided on the upper housing 110 or on the lower housing 120.

[0171] 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.

[0172] 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.

[0173] In some embodiments of this application, the second snap-fit ​​structure includes a snap-fit ​​and a snap-fit ​​groove. The snap-fit ​​groove can be disposed on the upper housing 110, and the corresponding snap-fit ​​can be disposed on the lower housing 120, or the snap-fit ​​groove can be disposed on the lower housing 120, and the corresponding snap-fit ​​can be disposed on the upper housing 110.

[0174] 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.

[0175] In some embodiments of this application, for ease of wiring, see [reference needed]. Figure 1As 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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. The expansion adapter 3000 and the controller 1000 together form a controller assembly.

[0181] 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.

[0182] 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).

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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'.

[0187] 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.

[0188] 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'.

[0189] See Figure 9 and Figure 10The 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.

[0190] 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'.

[0191] 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.

[0192] 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.

[0193] 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 the communication point of the expansion module 1000' and to lock the main control board 170' of the expansion module 1000'.

[0194] 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).

[0195] 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.

[0196] In some embodiments of this application, see Figure 10The 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.

[0197] 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.

[0198] 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.

[0199] 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'.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] 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.

[0205] 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. See [link to relevant documentation]. Figures 11 to 14 Multiple connecting parts 200 / 200A / 200B are also installed on the back of the housing 100 and can be switched between the first position and the second position.

[0206] The connecting parts 200 / 200A / 200B have the same structure, and the mechanism of the connecting part 200 will be used as an example for explanation.

[0207] See Figure 12 The connecting portion 200 is provided with a through portion 220 (e.g., a mounting hole), and when the connecting portion 200 is in the first position, the through portion 220 is at least partially covered by the housing 100 (see...). Figure 11 and Figure 12 That is, the through portion 220 is not fully exposed, and in this case, the through portion 220 cannot be used; when the connecting portion 200 is in the second position (see... Figure 13 When the through portion 220 extends beyond the housing 100 to fully expose the through portion 220, the through portion 220 can be used.

[0208] 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.

[0209] The first part and the second part are located on both sides of the avoidance part 121, respectively. Note that the first part is located on the first side of the avoidance part 121 and the second part is located on the second side of the avoidance part 121.

[0210] When the first part includes multiple connecting parts, the multiple connecting parts in the first part are arranged at intervals on the first side of the clearance part 121. When the second part includes multiple connecting parts, the multiple connecting parts in the second part are arranged at intervals on the second side of the clearance part 121.

[0211] When each of the first and second parts includes only one connecting part, the connecting parts of the first part and the connecting parts of the second part are arranged facing each other relative to the clearance part 121 to ensure the installation stability of the controller 1000 when it is fixedly installed using the connecting parts.

[0212] When one part has one connecting part and the other part has multiple connecting parts in the first and second parts, all connecting parts are arranged in a triangular pattern to ensure the stability of the controller 1000 when it is fixedly installed using connecting parts.

[0213] See Figure 11 and Figure 12 In some embodiments of this application, the first side of the avoidance portion 121 has two connecting portions 200 and 200A, and the second side of the avoidance portion 121 has a connecting portion 200B, and the three connecting portions 200 / 200A / 200B form a triangular arrangement.

[0214] See Figure 14 In some embodiments of this application, when the connecting portion 200 is installed on the back of the housing 100, the end of the connecting portion 200 near the avoidance portion 121 forms an engaging portion 210, and the end away from the avoidance portion 121 forms a through portion 220.

[0215] In some embodiments of this application, the connecting portion 200 can switch between a first position and a second position. Let the sliding direction of the connecting portion 200 when switching from the first position to the second position be the first direction. Figure 12 (As shown by the dotted-dash arrow), when switching from the second position to the first position, the sliding direction of the connecting part 200 is the second direction. Figure 12 (The dashed arrow shown in the image).

[0216] See Figure 11 and Figure 12 When the connecting part 200 is in the first position, the engaging part 210 extends into the avoidance part 121, and the engaging part 210 of the connecting part 200 engages with the first flange 2200 of the guide rail 2000.

[0217] 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, that is, the through portion 220 is not completely exposed. See [reference needed]. Figure 11 and Figure 12 .

[0218] 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 2000.

[0219] 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 [reference]). Figure 11 ).

[0220] 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. The guide rail 2000 can then 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...). Figure 13 That is, the through portion 220 can be fully seen from the front 111 of the housing 100.

[0221] 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.

[0222] As described above, after the guide rail 2000 can be removed from the clearance portion 121 when all the 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. In this way, multiple third fasteners are used to pass through the through portions 220 of at least one upper connecting portion and the through portions 220 of at least one lower connecting portion respectively, and are fixed to the wall. The 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.

[0223] The third fastener can be a screw or a nail without threads.

[0224] In some embodiments of this application, when the controller 1000 is fixedly installed, an upper connecting part can be selected and a 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.

[0225] In some embodiments of this application, when fixing the controller 1000, one upper connecting part and two lower connecting parts can be used, which form a triangle to ensure the triangular stable installation of the controller 1000.

[0226] 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 hole 123 / 123A or wall-mounted by means of the through part 220 of the connecting part 200 / 200A / 200B.

[0227] 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, so that the first fastener fixed to the wall can be hung through the wall mounting hole 123 / 123A.

[0228] In the above embodiment, the controller 1000 is suspended on the first fastener by the cooperation of the two wall mounting holes 123 / 123A, which can prevent the controller 1000 from swaying left and right, thereby stably suspending the controller 1000 on the wall.

[0229] 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, at least one connecting part (e.g., connecting part 200A) can be selected to be in the second position and the remaining connecting parts can be switched to the first position. In this way, the controller 1000 is fixed to the wall by the first fastener that is hung on the wall through the wall hole 123 / 123A, and at the same time, at least one second fastener is used to pass through the through part of the selected at least one connecting part 200A respectively. The controller 1000 is fixed to the wall by a combination of suspension and fixing.

[0230] The selected connector 200A and the two wall mounting holes 123 / 123A form a triangle to achieve stable fixing of the controller 1000.

[0231] As mentioned above, the two connecting parts can be selected from the two lower connecting parts (not shown) located in the lower connecting part, thereby avoiding the controller 1000 from shaking around.

[0232] 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).

[0233] In some embodiments of this application, in order to achieve the switching between the first and second positions of the connecting parts 200 / 200A / 200B, see [link to relevant documentation]. Figure 14The controller 1000 also includes a plurality of guide portions 122 / 122A / 122B, the number of which is consistent with the number of the plurality of connecting portions 200 / 200A / 200B. That is, a connecting portion 200 / 200A / 200B slides within a guide portion 122 / 122A / 122B to realize switching from a first position to a second position along a first direction, and switching from a second position to a first position along a second direction.

[0234] 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.

[0235] 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.

[0236] 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 15 and Figure 16 A decorative panel 150 can be provided to cooperate with the light guide assembly 180.

[0237] See Figure 15 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.

[0238] In some embodiments of this application, the decorative panel 150 on the controller 1000 is used as an example for illustration.

[0239] 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.

[0240] In some embodiments of this application, see Figure 16The 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.

[0241] 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 18 The cylindrical portion 114 is connected to the light guide recess 111.

[0242] 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.

[0243] 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.

[0244] In some embodiments of this application, see Figure 15 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.

[0245] In some embodiments of this application, an insertion slot is formed on the front side of the upper housing 110. Figure 16 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.

[0246] 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.

[0247] In some embodiments of this application, see Figure 16 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.

[0248] 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.

[0249] In some embodiments of this application, see reference 1. Figure 15 The display area includes a display grid hole 151, which is formed on the decorative panel 150.

[0250] 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.

[0251] In some embodiments of this application, see Figure 18 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.

[0252] In some embodiments of this application, see Figure 16 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.

[0253] In some embodiments of this application, see Figure 15 and Figure 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 display grid holes 151 as described above.

[0254] 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.

[0255] Correspondingly, see still Figure 15 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.

[0256] 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.

[0257] 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.

[0258] In some embodiments of this application, other text, logos, or patterns may also be provided on the decorative panel 150.

[0259] 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.

[0260] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0261] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
