Thus, the example term "below" can encompass both above and below orientations.

[0053] As shown in Figures 1 and 2, in some embodiments of the present invention, the controller 100 includes a mounting plate 10 and a control module 20. The control module 20 has electronic components for transmitting control signals to the air conditioner, such as control buttons, control knobs, and display screens. The control module 20 is installed on a junction box 200 or a pre-installed accessory 300 such as a cabinet or wall through the mounting plate 10.

[0054] In the present invention, the controller includes but is not limited to a wired controller or a centralized controller.

[0055] In this embodiment, please refer to Figures 1, 4 and 5, the mounting plate 10 has a bottom 101 and a top 102 that are relatively set. Generally, when the mounting plate 10 is installed on the junction box 200, when the junction box 200 is placed on the wall, the top 102 is set to face upward and the bottom 101 is set to face downward. It can be understood that in other installation scenarios, if the junction box 200 is placed horizontally, the top 102 faces the side away from the operator and the bottom 101 faces the side close to the operator.

[0056] Furthermore, the control module 20 has a first side 201 and a second side 202 arranged opposite each other. The mounting plate 10 is provided with a first anti-mock structure 12, and the control module 20 is provided with a second anti-mock structure 214 that matches the first anti-mock structure 12. The first anti-mock structure 12 matches the second anti-mock structure 214. When the control module 20 is mounted on the mounting plate 10, the first anti-mock structure 12 and the second anti-mock structure 214 are connected. In this embodiment, the cooperation between the first anti-mock structure 12 and the second anti-mock structure 214 can limit the control module 20 to be installed in the mounting plate 10 in the forward direction, preventing the control module 20 from being installed upside down. Specifically, the forward direction refers to the direction in which the first side 201 is opposite the bottom 101 and the second side 202 is opposite the top 102.

[0057] It is understandable that if the installation direction of the control module 20 is inverted, the first fool-proofing mechanism and the second fool-proofing structure 214 cannot be adapted, so that the control module 20 cannot be invertedly installed on the mounting plate 10.

[0058] In some embodiments, the mounting plate 10 includes a plate body 11 and an ear plate 121 connected to the plate body 11, the plate body 11 is frame-shaped and defines an opening 111, the ear plate 121 is arranged at the inner edge of the plate body 11 and extends toward the opening 111, wherein the first anti-foolproofing structure 12 includes the ear plate 121, and the second anti-foolproofing structure 214 includes an assembly groove 2141 formed in the control module 20, the assembly groove 2141 is arranged at one end of the control module 20 facing the mounting plate 10, the contour of the assembly groove 2141 matches the ear plate 121, and the contour of each assembly groove 2141 matches the contour of a unique ear plate 121, so as to achieve an anti-foolproofing effect during the connection process between the control module 20 and the mounting plate 10.

[0059] In some specific examples, the specific shapes of the ear plate 121 and the assembly slot 2141 can be optimized to establish a unique alignment between the two, thereby defining the installation direction of the control module 20 and the mounting bracket 10. For example, if there is only one ear plate 121 and one assembly slot 2141, the outline of the ear plate 121 is asymmetrical, and the outline of the assembly slot 2141 matches the outline of the ear plate 121. Therefore, the control module 20 can only be installed on the mounting bracket 10 in the forward direction. If installed in the reverse direction, the ear plate 121 and the assembly slot 2141 will not match, making it impossible to install the control module 20 in the reverse direction on the mounting bracket 10. For another example, when the number of ear plates 121 and the number of assembly slots 2141 are two or more respectively, the contour shapes of each ear plate 121 are different. For example, when the number of ear plates 121 is two, one ear plate 121 is set to be rectangular, and the other ear plate 121 is set to be elliptical. Among the two assembly slots 2141, the contour of one assembly slot 2141 matches the rectangular ear plate 121, and the contour of the other assembly slot 2141 matches the elliptical ear plate 121. Therefore, the control module 20 and the mounting plate 10 have a unique and definite installation method, which can prevent inversion.

[0060] In other specific embodiments, the position of the ear plate 121 on the mounting plate 10 can be optimized to ensure that the control module 20 and the mounting plate 10 have a unique alignment relationship, thereby limiting the installation direction of the control module 20 and the mounting plate 10. The feasible implementation schemes are as follows:

[0061] In this embodiment, please refer to Figures 1, 3 and 5. When the control module 20 is installed on the mounting plate 10, the control module 20 is passed through the opening 111 and the circumferential outer contour of the control module 20 is against the inner edge of the opening 111. The ear plate 121 is arranged in the assembly groove 2141, and the circumferential outer contour of the ear plate 121 cooperates with the inner wall of the assembly groove 2141, thereby limiting the position between the control component and the mounting plate 10.

[0062] Furthermore, along the first direction, the opening 111 has a first inner edge 1111 and a second inner edge 1112 arranged opposite to each other along the first direction, the opening 111 has a symmetry line 112 that bisects itself, the distance between the ear plate 121 and the first inner edge 1111 is greater than the distance between the ear plate 121 and the second inner edge 1112, or the distance between the ear plate 121 and the first inner edge 1111 is less than the distance between the ear plate 121 and the second inner edge 1112, so that the ear plate 121 is set deviating from the symmetry line 112. Since the ear plate 121 is set away from the line of symmetry 112, and the circumferential outer contour of the control module 20 is against the inner edge of the opening 111, when the control module 20 is installed on the mounting plate 10 in a first direction, the ear plate 121 is opposite to the assembly groove 2141 and can enter into the assembly groove 2141. However, when the control module 20 is installed on the mounting plate 10 in a reverse direction, based on the limiting effect of the circumferential outer contour of the control module 20 and the inner edge of the opening 111, the assembly groove 2141 and the ear plate 121 are misaligned, and the ear plate 121 interferes with the control module 20, thereby preventing the control module 20 from being inserted into the opening 111 and moving to the assembly position with the mounting plate 10.

[0063] The symmetry line 112 bisecting the opening 111 means that the distance from the symmetry line 112 to the first inner edge 1111 is equal to the distance from the symmetry line 112 to the second inner edge 1112 .

[0064] In some embodiments of the present invention, as shown in FIG3 , the first fool-proof structure 12 includes two lugs 121 , each disposed on two opposing inner edges of the hanging plate body 11 along a second direction perpendicular to the first direction. Both lugs 121 are disposed on the same side of the symmetry line 112 .

[0065] In some embodiments of the present invention, as shown in Figures 1, 2, and 3, the ear plate 121 is provided with a first connection portion 13, and the hanging plate body 11 is provided with a second connection portion 14. The first connection portion 13 and the second connection portion 14 are selectively connected to a pre-assembled accessory. The pre-assembled accessory 300 can be provided as a frame-shaped plate-like member. The first connection portion 13 can be used to connect to the junction box 200, and the second connection portion 14 can be used to connect to the frame-shaped pre-assembled accessory 300. At least a portion of the control module 20 can be inserted through the connector or extend into the junction box 200 through the opening 111. By providing the first connection portion 13 and the second connection portion 14 on the ear plate 121 and the hanging plate body 11, respectively, the controller 100 provided by the present invention can be installed on components in different installation scenarios. The controller 100 can be installed in a junction box 200, such as an 86 box, or on a frame-shaped connector, making the controller 100 compatible with a wider range of application scenarios.

[0066] The frame-shaped pre-assembled component 300 may be a cabinet door of a control cabinet, a wall or a wall surface of furniture with a square receiving space and an opening for inserting the controller 100 .

[0067] Furthermore, the first connecting portion 13 includes an assembly hole 131 provided on the ear plate 121, and the assembly hole 131 is used to correspond to the mounting hole 2001 in the junction box 200. The hole distance between the two assembly holes 131 ranges from 58 mm to 62 mm. For example, the hole distance between the two assembly holes 131 can be set to one of 58 mm, 59 mm, 59.5 mm, 60 mm, 60.5 mm, 61 mm or 62 mm, so as to adapt to the two mounting holes 2001 in the junction box 200.

[0068] In this embodiment, as shown in Figure 3, the opening 111 and the ear plate 121 are both axially symmetrical in shape, the assembly hole 131 is set as a waist-shaped hole, the shape of the assembly hole 131 corresponds to the shape of the mounting hole 2001 in the junction box 200, the ear plate 121 is in an arc-shaped plate shape and has an axis of symmetry, the central axis of the assembly hole 131 coincides with the symmetry line 112 of the opening 111, and the central axis of the assembly hole 131 and the symmetry axis of the ear plate 121 are spaced apart.

[0069] The second connecting portion 14 includes at least one connecting hole 141 provided on the hanging plate body 11. The installation hanging plate 10 can be connected to the cabinet door by passing a connecting member such as a bolt through the connecting hole 141, or the installation hanging plate 10 can be connected to the wall by passing a connecting member such as an expansion screw through the connecting hole 141.

[0070] In some embodiments, as shown in Figures 2 and 3, the second connecting portion 14 includes four connecting holes 141, and the four connecting holes 141 are respectively arranged at the four corners of the hanging plate body 11. The hanging plate 10 can be connected to the cabinet door through four connecting parts, thereby improving the connection strength between the hanging plate 10 and the pre-assembled accessories 300 such as the cabinet door.

[0071] In some embodiments of the present invention, as shown in Figures 1, 2, and 3, mounting bracket 10 is provided with an indicator 103. Indicator 103 is arranged along a first direction and points toward top 102. Indicator 103 is used to provide directional guidance to the installer, thereby facilitating the installer's correct installation of mounting bracket 10 onto a pre-assembled accessory 300, such as a junction box 200 or a cabinet door, and preventing the mounting bracket 10 from being installed upside down. In this embodiment, indicator 103 includes one or more of an arrow, text, or letters.

[0072] In this embodiment, as shown in Figures 4, 5 and 6, the control module 20 includes a power supply back cover 21 and an upper cover 22. The power supply back cover 21 includes a connected back cover portion 211 and a convex portion 212. The back cover portion 211 is hollow box-shaped and has an opening formed on one side. The convex portion 212 is arranged on the outer peripheral surface of the back cover portion 211 and surrounds the outer peripheral surface of the back cover portion 211. The convex portion 212 is annular as a whole and is arranged around the opening and extends along the circumference of the back cover portion 211 in a direction away from the opening. When the back cover portion 211 is inserted into the opening 111, the convex portion 212 is abutted against the hanging plate body 11 of the mounting hanging plate 10. The upper cover 22 is connected to the power supply back cover 21 and seals the opening, so that a space for accommodating electronic components in the control module 20 is defined between the upper cover 22 and the power supply back cover 21.

[0073] In this embodiment, the assembly groove 2141 is formed on the outer peripheral surface of the rear cover portion 211. When the rear cover portion 211 is inserted into the opening 111, the circumferential outer contour of the rear cover portion 211 is abutted against the inner edge of the opening 111, and the ear plate 121 can enter into the assembly groove 2141.

[0074] In some embodiments of the present invention, please refer to Figures 2 and 4, the convex edge 212 is provided with a plurality of avoidance grooves 2121, and the avoidance grooves 2121 are arranged one-to-one corresponding to the connection holes 141. After the mounting plate 10 is fixed to the cabinet door by countersunk screws, the control module 20 is installed on the mounting plate 10. The avoidance grooves 2121 are used to provide installation space for the countersunk screws to avoid interference between the countersunk screws and the power back cover 21.

[0075] In some embodiments of the present invention, as shown in Figures 4 and 6, the rear cover 211 is further provided with at least one clip 213, and the power supply rear cover 21 is snapped with the mounting plate 10 through the clip 213, so that when the mounting plate 10 is installed to the junction box 200 or the cabinet door, the control module 20 can be quickly installed on the mounting plate 10, which is conducive to the rapid disassembly of the control module 20, shortening the maintenance time during the subsequent maintenance work and reducing the maintenance cost.

[0076] In some embodiments, the number of clips 213 may be multiple and spaced apart along the circumference of the rear cover 211 , thereby increasing the snap connection strength between the power supply rear cover 21 and the mounting plate 10 and improving the stability of the controller 100 after installation.

[0077] In some embodiments, please refer to Figures 1, 6 and 7, the buckle 213 includes a cantilever portion 2131 and a protrusion 2132. The cantilever portion 2131 is in the shape of a long strip, and one end of the cantilever portion 2131 is suspended in a cantilever shape. The protrusion 2132 is arranged at the free end of the cantilever portion 2131, and the protrusion 2132 and the flange portion 212 are spaced apart. When the power back cover 21 is inserted into the opening 111 and connected to the mounting plate 10, along the insertion direction of the power back cover 21, the protrusion 2132 moves from one side of the mounting plate 10 to the other side and clamps the mounting plate 10 between the protrusion 2132 and the flange portion 212 by cooperating with the flange portion 212, thereby realizing the snap connection between the power back cover 21 and the mounting plate 10. Among them, the purpose of setting the cantilever portion 2131 in a cantilever shape is that when the protrusion 2132 moves from one side of the mounting plate 10 to the other side, the cantilever portion 2131 can bend under the pressure of the mounting plate 10, so that the protrusion 2132 can avoid the mounting plate 10, and when the mounting plate 10 is between the protrusion 2132 and the flange portion 212, the cantilever portion 2131 elastically recovers so that the protrusion 2132 can cooperate with the end face stop on the side of the mounting plate 10 away from the flange portion 212, thereby realizing a snap connection between the mounting plate 10 and the power supply back cover 21.

[0078] In this embodiment, the extension direction of the cantilever portion 2131 is parallel to the plugging direction of the power back cover 21 .

[0079] In some embodiments, as shown in combination with Figures 1, 6 and 7, along the plugging direction of the buckle 213, the end of the protrusion 2132 away from the flange 212 is configured as a first guide surface 21321 inclined relative to the mounting plate 10. The first guide surface 21321 is used when the power back cover 21 is installed on the mounting plate 10. When the mounting plate 10 first abuts against the first guide surface 21321 of the buckle 213, and under the guiding action of the first guide surface 21321, the pressure of the mounting plate 10 acting on the first guide surface 21321 has a component force perpendicular to the cantilever portion 2131. This component force can drive the cantilever portion 2131 to bend, so that the protrusion 2132 can avoid the mounting plate 10, so that the power back cover 21 can be smoothly snapped onto the mounting plate 10.

[0080] In some embodiments, as shown in combination with Figures 1, 6 and 7, along the plugging direction of the buckle 213, the protrusion 2132 is configured as a second guide surface 21322 inclined relative to the mounting plate 10 toward one end of the flange 212, and the first guide surface 21321 is used to make the mounting plate 10 first abut against the second guide surface 21322 of the buckle 213 during the process of removing the power back cover 21 from the mounting plate 10, and under the guiding action of the second guide surface 21322, the pressure of the mounting plate 10 acting on the second guide surface 21322 has a component force perpendicular to the cantilever portion 2131, and this component force can drive the cantilever portion 2131 to bend, so that the protrusion 2132 can avoid the mounting plate 10, so that the power back cover 21 can be smoothly removed from the mounting plate 10.

In this embodiment, the disassembly guide buckle 122 cooperates with the guide groove 2142 provided on the control module 20 to ensure that the control module 20 and the mounting plate 10 have a unique assembly orientation, thereby preventing the control module 20 from being installed upside down on the mounting plate 10.

[0082] Furthermore, the disassembly guide buckle 122 extends from one end of the mounting plate body 11 toward a side away from the opening 111. The guide groove 2142 extends in the same direction as the disassembly guide buckle 122. Along the extension direction of the guide groove 2142, the guide groove 2142 sequentially passes through the power supply rear cover 21 and the upper cover 22, forming a disassembly opening at the edge of the upper cover 22. When the control module 20 is engaged with the mounting plate 10, the disassembly guide buckle 122 is inserted into the guide groove 2142. To remove the control module 20 from the mounting plate 10, a screwdriver can be inserted through the disassembly opening into the guide groove 2142 and between the disassembly guide buckle 122 and the ridge 212. The screwdriver can then be used to pry the disassembly guide buckle 122, thereby conveniently removing the control module 20 from the mounting plate 10 and separating the control module 20 from the mounting plate 10.
