[0049] like Figures 1 to 9 In the middle, the first direction, the second direction, and the third direction are perpendicular to each other. The first direction refers to the thickness direction of the display motherboard 3, the second direction refers to one of the thickness direction and the length direction of the display motherboard 3, and the third direction refers to the other of the thickness direction and the length direction of the display motherboard 3.

[0050] like Figures 1 to 3 As shown, an embodiment of the present invention provides a wired controller housing and a wired controller. The wired controller includes a display motherboard 3 and a wired controller housing. The wired controller housing includes a front cover 1 and a rear cover 2 distributed and connected along a first direction. The bottom wall of the rear cover 2 is recessed in a direction away from the front cover 1 to form a receiving groove 24. The front cover 1 is provided with two mounting structures, namely a first mounting structure and a second mounting structure.

[0051] The display motherboard 3 includes a first display motherboard 3a or a second display motherboard 3b. The thickness of the first display motherboard 3a is greater than the thickness of the second display motherboard 3b. The first display motherboard 3a is the display motherboard 3 of a high-voltage wire controller, which is used to connect to a 220V AC power supply. The second display motherboard 3b is the display motherboard 3 of a low-voltage wire controller, which is used to connect to a DC power supply of no more than 15V.

[0052] The first mounting structure has multiple flush first support surfaces for supporting the first display motherboard 3a along a first direction; the second mounting structure has a second support surface for supporting the second display motherboard 3b along the first direction. The first support surface is closer to the rear cover 2 along the first direction than the second support surface, and the projections of the first support surface and the second support surface onto a plane perpendicular to the second direction at least partially overlap.

[0053] For the first display motherboard 3a and the second display motherboard 3b with different maximum thicknesses, the first support surface is positioned closer to the back cover 2 along the first direction than the second support surface, and the first support surface and the second support surface are arranged at intervals along the first direction; for the first display motherboard 3a and the second display motherboard 3b with different maximum lengths along the third direction, the first support surface and the second support surface are arranged at intervals along the second direction, and the projections of the first support surface and the second support surface on a plane perpendicular to the second direction are at least partially overlapping.

[0054] When the wire controller housing is used for a high-voltage wire controller, the transformer and other components of the high-voltage wire controller are installed in the receiving groove 24, and the first display main board 3a of the high-voltage wire controller is abutted against the first support surface along the first direction through the first mounting structure, so as to install the first display main board 3a in the front cover 1; when the wire controller housing is used for a low-voltage wire controller, the second display main board 3b of the low-voltage wire controller is abutted against the second support surface along the first direction through the second mounting structure, so as to install the second display main board 3b in the front cover 1, so that the high-voltage wire controller and the low-voltage wire controller can use the same wire controller housing, improving the versatility of the wire controller housing; moreover, only the same mold needs to be used to manufacture the wire controller housing, reducing the manufacturing cost of the wire controller housing.

[0055] In addition, the first mounting structure includes multiple flush first support surfaces, which facilitate the opening of clearance holes in the openable area on the circumferential side of the second display motherboard 3b to allow clearance for the first mounting structure.

[0056] In some embodiments, the first mounting structure includes a first fixed support portion 112 protruding from the inner wall of the front cover 1, and a plurality of first support surfaces including a first fixed support surface 1121 disposed on the first fixed support portion 112. The first fixed support portion 112 is provided with a first threaded mounting hole 1122 extending at one end along a first direction to the first fixed support surface 1121, for connection with a first mounting through hole 3a4 on the first display motherboard 3a via a first motherboard fastener. This configuration enables the first display motherboard 3a to be fixed to the front cover 1 via the first motherboard fastener when supported by the first fixed support surface 1121, thereby improving the stability of the first display motherboard 3a.

[0057] The second mounting structure includes a second fixed support portion 122 protruding from the inner wall of the front cover 1. Multiple second support surfaces are provided, including a second fixed support surface 1221 located on the second fixed support portion 122. The second fixed support portion 122 has a second threaded mounting hole 1222 extending at one end along a first direction to the first fixed support surface 1121, for connection with the second mounting through hole 3b6 on the second display motherboard 3b via a second motherboard fastener. This configuration allows the second display motherboard 3b to be fixed to the front cover 1 via the second motherboard fastener when supported by the second fixed support surface 1221, thus improving the stability of the second display motherboard 3b.

[0058] In some embodiments, the inner wall of the front cover 1 is provided with a front limiting surface perpendicular to the first direction, for abutting against either the display surface of the first display motherboard 3a or the display surface of the second display motherboard 3b. Specifically, the two sides of the display motherboard 3 in the thickness direction are respectively the display surface and the non-display surface, and the display interface of the display motherboard 3 is located on the display surface of the display motherboard 3. The front cover 1 has a display hole through which the display interface of the display motherboard 3 is exposed, making it convenient for the user to observe the display interface. Both the first display motherboard 3a and the second display motherboard 3b can abut against the front limiting surface, and the display hole can also be completely covered by the display motherboard.

[0059] In some embodiments, the display motherboard 3 includes a first motherboard and a second motherboard protruding from one side of the thickness direction of the first motherboard, with the first motherboard extending out of the second motherboard along both a second direction and a third direction.

[0060] To improve the stability of the first display motherboard 3a, such as Figure 3As shown, the first mounting structure also includes a first limiting support portion 111 protruding from the inner wall of the front cover 1. A plurality of first support surfaces include a first limiting support surface one 1111. The first limiting support portion 111 is provided with a first limiting groove. The two side walls of the first limiting groove, which are arranged opposite to each other along the first direction, respectively form the first limiting support surface one 1111 and the first limiting support surface two 1112. The first limiting support surface one 1111 is located between the first limiting support surface two 1112 and the front limiting surface along the first direction, and is used to clamp the first display motherboard 3a between the first limiting support surface two 1112 and the first limiting support surface two 1112 along the first direction.

[0061] Specifically, the first motherboard of the first display motherboard 3a is sandwiched between the first limiting support surface 1111 and the second limiting support surface 1112 along the first direction.

[0062] To improve the stability of the second display motherboard 3b, such as Figure 3 As shown, the plurality of second support surfaces include a second limiting support surface 1211, and the second mounting structure includes a second limiting support portion 121 protruding from the inner wall of the front cover 1. The second limiting support portion 121 is provided with a second limiting groove. The two side walls of the second limiting groove, which are arranged opposite to each other along the first direction, respectively form the aforementioned second limiting support surface 1211 and the second limiting support surface 1212. The second limiting support surface 1211 is located between the second limiting support surface 1212 and the front limiting surface along the first direction, and is used to clamp the second display motherboard 3b between the second limiting support surface 1212 and the second limiting support surface 1212 along the first direction.

[0063] Specifically, the first motherboard of the second display motherboard 3b is sandwiched between the second limiting support surface 1211 and the second limiting support surface 1212 along the first direction, and the second fixed support surface 1221 is flush with the second limiting support surface 1211.

[0064] When installing the first display motherboard 3a, simply insert one end of the first display motherboard 3a into the corresponding first limiting groove along the third direction, so that the first display motherboard 3a is clamped between the first limiting support surface 1111 and the second limiting support surface 1211 at one end along the first direction. At the other end of the first display motherboard 3a, it is supported by the first fixed support surface 1121, and the first motherboard fastener passes through the first mounting through hole 3a4 on the first display motherboard 3a and is threaded to the first threaded mounting hole 1122 on the first fixed support part 112 to fix the first display motherboard 3a to the front cover 1. The installation method of the first display motherboard 3a is simple and the disassembly and assembly are convenient and quick.

[0065] When installing the second display motherboard 3b, simply insert one end of the second display motherboard 3b into the corresponding second limiting groove along the third direction, so that the second display motherboard 3b is clamped between the second limiting support surface 1211 and the second limiting support surface 1212 at one end along the first direction. At the other end of the second display motherboard 3b, it is supported by the second fixed support surface 1221. The second motherboard fastener passes through the second mounting through hole 3b6 on the second display motherboard 3b and is threaded to the second threaded mounting hole 1222 on the second fixed support part 122 to fix the second display motherboard 3b to the front cover 1. The installation method of the second display motherboard 3b is simple and the disassembly and assembly are convenient and quick.

[0066] When the wire controller housing is used in a high-voltage wire controller, the first display main board 3a is sandwiched between the first limiting support surface 1112 and the front limiting surface along the first direction. When the wire controller housing is used in a low-voltage wire controller, the second display main board 3b is sandwiched between the second limiting support surface 1212 and the front limiting surface. This arrangement allows the first and second display main boards 3a and 3b to share the front limiting surface. Based on the maximum thickness difference between the first and second display main boards 3a and 3b, the thickness of the first and second support surfaces is spaced apart along the first direction to meet the installation requirements of the first and second display main boards 3a and 3b.

[0067] For example, the front cover 1 includes a front cover bottom and a first side wall, a second side wall, a third side wall and a fourth side wall surrounding the periphery of the front cover bottom, wherein the first side wall and the third side wall are disposed opposite each other along a third direction, and the second side wall and the fourth side wall are disposed opposite each other along a second direction.

[0068] The first limiting support portion 111 and the second limiting support portion 121 both protrude from the inner sidewall of the first sidewall, with one end of the first limiting support portion 111 and one end of the second limiting support portion 121 extending to the bottom of the front cover. The first fixing support portion 112 and the second fixing support portion 122 both protrude from the inner wall of the bottom of the front cover. To improve stability, the inner wall of the bottom of the front cover is provided with a first reinforcing rib connected to the first fixing support portion 112, thereby improving the connection stability between the first fixing support portion 112 and the bottom of the front cover; the inner wall of the bottom of the front cover is provided with a second reinforcing rib connected to the second fixing support portion 122, thereby improving the connection stability between the second fixing support portion 122 and the bottom of the front cover.

[0069] In some embodiments, such as Figure 3As shown, at least two first limiting support portions 111 are provided and arranged at intervals along the second direction, and at least two first fixed support portions 112 are provided and arranged at intervals along the second direction. For the first display motherboard 3a, it can be limited along the first direction by multiple first limiting support portions 111, supported by multiple first fixed support portions 112, and fastened by first motherboard fasteners, which helps to improve the connection stability between the first display motherboard 3a and the front cover 1.

[0070] At least two second limiting support portions 121 are provided and arranged at intervals along the second direction, and at least two second fixed support portions 122 are provided and arranged at intervals along the second direction. For the second display motherboard 3b, it can be limited along the first direction by multiple second limiting support portions 121, supported by multiple second fixed support portions 122, and fastened by second motherboard fasteners, which helps to improve the connection stability between the second display motherboard 3b and the front cover 1.

[0071] For example, there are two first limiting support parts 111 and two first fixed support parts 112, and there are two second limiting support parts 121 and two second fixed support parts 122.

[0072] In some embodiments, such as Figures 4 to 8 As shown, since the maximum thickness of the first display motherboard 3a is greater than the maximum thickness of the second display motherboard 3b, the second support surface is located between the first support surface and the front limit surface along the first direction.

[0073] In order to avoid interference with the installation of the second display motherboard 3b by the first mounting structure used to install the first display motherboard 3a, the second display motherboard 3b is provided with a clearance hole on its circumferential sidewall to avoid the second mounting structure that installs the first display motherboard 3a on the front cover 1.

[0074] Specifically, the clearance holes on the second display motherboard 3b include a first clearance hole 3b1 and a second clearance hole 3b2. When the second display motherboard 3b is installed on the front cover 1 through the first mounting structure, the first limiting support part 111 passes through the first clearance hole 3b1 along the first direction, and the first fixing support part 112 passes through the second clearance hole 3b2 along the first direction.

[0075] For example, along the first direction, the end face of the second limiting support 121 near the end of the rear cover 2 is located between the end face of the first limiting support 111 near the end of the rear cover 2 and the first limiting support surface 1111.

[0076] To prevent the second limiting support 121 from interfering with the installation of the first display motherboard 3a, the first display motherboard 3a is provided with a first clearance hole 3a1 for avoiding the second limiting support 121. When the first display motherboard 3a is installed on the front cover 1 through the second mounting structure, the first limiting support 111 passes through the first clearance hole 3a1 in the first direction.

[0077] In some embodiments, such as Figures 4 to 8 As shown, the inner wall of the front cover 1 is provided with a positioning member 13, which is used to be inserted and positioned with the first positioning part 3a3 on the first display motherboard 3a along the first direction, and to be inserted with the second positioning part 3b5 on the second display motherboard 3b along the first direction. When installing the first display motherboard 3a, the positioning member 13 and the first positioning part 3a3 are inserted along the first direction, which allows the first threaded mounting hole 1122 and the first mounting through hole 3a4 to be aligned, facilitating the installation of the first display motherboard 3a onto the front cover 1 using the first motherboard fasteners. When installing the second display motherboard 3b, the positioning member 13 and the second positioning part 3b5 are inserted along the first direction, which allows the second threaded mounting hole 1222 and the second mounting through hole 3b6 to be aligned, facilitating the installation of the second display motherboard 3b onto the front cover 1 using the second motherboard fasteners.

[0078] For example, the positioning member 13 is a motherboard positioning protrusion protruding from the inner wall of the bottom of the front cover, the first positioning part 3a3 is a first positioning hole provided on the first display motherboard 3a, and the second positioning part 3b5 is a second positioning hole provided on the second display motherboard 3b. The motherboard positioning protrusion can be inserted into the first positioning hole along the first direction and can also be inserted into the second positioning hole along the first direction.

[0079] In some embodiments, such as Figures 4 to 8 As shown, the first mounting structure also includes a first auxiliary support portion 113 protruding from the inner wall of the front cover 1, and the plurality of first support surfaces also include a first auxiliary support surface 1131 disposed on the first auxiliary support portion 113. The first auxiliary support surface 1131 is used to provide auxiliary support for the first display motherboard 3a to improve the stability of the first display motherboard 3a.

[0080] For example, the first auxiliary support portion 113 and the first limiting support portion 111 are located on the same side of the front cover 1 in the second direction. There are two first auxiliary support portions 113. The first limiting support portion 111 is disposed between the two first auxiliary support portions 113 along the second direction. The first auxiliary support portion 113 protrudes from the inner sidewall of the first sidewall. One end of the first auxiliary support portion 113 extends to the inner wall of the bottom of the front cover.

[0081] For example, the first auxiliary support surface 1131, the first limiting support surface 1111, and the first fixed support surface 1121 abut against the same side of the first display motherboard 3a.

[0082] When installing the second display motherboard 3b, the first fixed support part 112 used to install the first display motherboard 3a will not interfere with the installation of the second display motherboard 3b, so there is no need to set corresponding clearance holes on the second display motherboard 3b.

The second auxiliary support portion 123 protrudes from the inner sidewall of the first sidewall, and one end of the second auxiliary support portion 123 extends to the inner wall of the bottom of the front cover.

[0085] For example, the second auxiliary support surface 1231, the second limiting support surface 1211, and the second fixed support surface 1221 are flush with each other and abut against the same side of the second display motherboard 3b.

[0086] In order to avoid the first auxiliary support 113 interfering with the installation of the second display motherboard 3b, the clearance hole on the second display motherboard 3b also includes a second clearance hole 3b3. When the second display motherboard 3b is installed on the front cover 1, the first auxiliary support 113 passes through the second clearance hole 3b3.

[0087] In some embodiments, such as Figure 1 , Figure 3 and Figure 9 As shown, one of the front cover 1 and the rear cover 2 is provided with a first latching hole 21, and the other is provided with a first latch 14, which is latched into the first latching hole 21. The front cover 1 and the rear cover 2 are latched together, which can improve the ease of disassembly and assembly between the front cover 1 and the rear cover 2.

[0088] For example, the first buckle 14 is provided on the front cover 1 and the first latch 21 is provided on the rear cover 2. When the wired controller housing is used as a wired controller for a heating furnace, the rear cover 2 of the wired controller is usually built in and the front side of the front cover 1 is exposed. By providing the first latch 21 on the rear cover 2, the first latch 21 can be avoided from being exposed and affecting the aesthetics, and at the same time, moisture is prevented from entering the wired controller through the first latch 21.

[0089] Specifically, the first buckle 14 includes a buckle one, which protrudes from the first side wall and extends one end to the bottom of the front cover, while the other end extends out of the front cover 1 along the first direction; the first latch 21 includes a latch hole one, the rear cover 2 includes the bottom of the rear cover, and a fifth side wall, a sixth side wall, a seventh side wall, and an eighth side wall surrounding the bottom of the rear cover, wherein the fifth side wall and the seventh side wall are arranged opposite each other along the third direction, the sixth side wall and the eighth side wall are arranged opposite each other along the second direction, the inner wall of the first side wall protrudes with a buckle one, the fifth side wall has a latch hole one, the buckle one is latched in the latch hole one, and the bottom of the rear cover is recessed along the first direction away from the front cover 1 to form the aforementioned receiving groove 24.

[0090] The first buckle 14 also includes a second buckle, which protrudes from the third side wall and extends one end to the bottom of the front cover, while the other end extends out of the front cover 1 along the first direction; the first latch 21 also includes a second latch, which is provided on the seventh side wall, and the second buckle is latched in the second latch.

[0091] In some embodiments, such as Figure 1 , Figure 3 and Figure 9 As shown, there are at least two snap fasteners, which are spaced apart along the second direction; there are at least two snap fasteners, which are spaced apart along the second direction. This arrangement improves the engagement stability between the front cover 1 and the rear cover 2.

[0092] For example, there are two buckles, which are spaced apart along the second direction, and the buckles and the holes are engaged in a one-to-one correspondence; there are two buckles, which are spaced apart along the second direction, and the buckles and the holes are engaged in a one-to-one correspondence.

[0093] In some embodiments, such as Figure 1 As shown, the front cover 1 and the rear cover 2 form a disassembly notch 15. One end of the disassembly notch 15 is exposed. The disassembly notch 15 is used to insert a disassembly tool, so that the disassembly tool applies force to disengage the first buckle 14 from the first buckle hole 21.

[0094] For example, the front cover 1 has a disassembly notch 15 on its surface facing the rear cover 2 in a first direction and capable of contacting the rear cover 2, and one end of the disassembly notch 15 extends to the outer wall of the front cover 1.

[0095] When the online controller is applied to equipment such as hot water boilers, the front cover 1 is exposed, which exposes the disassembly notch 15. When it is necessary to remove the front cover 1, one end of the disassembly tool can be inserted into the disassembly notch 15 and pressed on the surface of the rear cover 2 facing the front cover 1 in the first direction. The other end of the disassembly tool is used to press the first buckle 14 and the first clip hole 21 to disengage, thereby removing the front cover 1 and improving the ease of disassembly and assembly between the front cover 1 and the rear cover 2.

[0096] In some embodiments, the disassembly notch 15 and the second latch are located on the same side wall of the front cover 1, which makes it easier for the second latch and the second latch hole to disassemble when the front cover 1 and the rear cover 2 are disassembled using disassembly tools. Furthermore, it ensures that the holes in the front cover 1 are located on the same side of the front cover 1, improving the aesthetics of the other side walls. In other embodiments, the disassembly notch 15 and the first latch can also be located on the same side wall of the front cover 1.

[0097] In some embodiments, the first display motherboard 3a is provided with a first mounting clearance groove 3a2 to avoid the first latch 14 from interfering with the installation of the first display motherboard 3a. The second display motherboard 3b is provided with a second mounting clearance groove 3b4 to avoid the first latch 14 from interfering with the installation of the second display motherboard 3b.

[0098] It should be noted that all the clearance slots and holes on the first display motherboard 3a, as well as the clearance slots and holes on the second display motherboard 3b, are located in the openable area of ​​the display motherboard 3.

[0099] In some embodiments, such as Figure 2 As shown, the wired controller also includes a circuit board 4 and a heat insulation plate 5, both located within the rear cover 2. The circuit board 4 is used to supply power to the display motherboard 3, and the heat insulation plate 5 is located between the display motherboard 3 and the circuit board 4 along the first direction. In other words, the display motherboard 3 and the circuit board 4 are located on opposite sides of the heat insulation plate 5 in the first direction.

[0100] The heat insulation plate 5 separates the circuit board 4 and the display motherboard 3, preventing the heat generated by the circuit board 4 from being transferred into the front cover 1 and affecting the normal operation of the display motherboard 3. The rear cover 2 is provided with heat dissipation holes to dissipate the heat generated by the circuit board 4 inside the rear cover 2.

[0101] In some embodiments, such as Figure 2 and Figure 9 As shown, the inner wall of the receiving groove 24 is provided with a power support protrusion 23, and the back cover 2 is provided with a second buckle 22. The circuit board 4 is sandwiched between the power support protrusion 23 and the second buckle 22 along the first direction.

[0102] When disassembling circuit board 4, simply pull out circuit board 4 along the first direction to the side where front cover 1 is located. The fixing method of circuit board 4 is simple and convenient to disassemble and assemble.

[0103] For example, multiple second buckles 22 are provided, and the multiple second buckles 22 are arranged at intervals along the circumferential direction of the receiving groove 24, and multiple power support protrusions 23 are provided.

[0104] In some embodiments, such as Figure 2 and Figure 9As shown, the inner wall of the rear cover 2 is provided with a heat insulation positioning protrusion 25, and the heat insulation plate 5 is provided with a heat insulation positioning hole 51. The heat insulation positioning protrusion 25 and the heat insulation positioning hole 51 are inserted and engaged in the first direction to limit the heat insulation plate 5 in the second and third directions, prevent the heat insulation plate 5 from shaking, and improve the stability of the heat insulation plate 5.

[0105] For example, the heat insulation positioning protrusion 25 protrudes from the open end face of the receiving groove 24, and the projection of the heat insulation positioning protrusion 25 on the plane perpendicular to the first direction is an ellipse, with the major axis direction and minor axis direction of the ellipse, one of which is the second direction and the other is the third direction.

[0106] For example, there are two heat insulation positioning protrusions 25, which are spaced apart along a third direction and whose long axis is perpendicular.

[0107] In some embodiments, such as Figure 2 and Figure 9 As shown, the heat insulation positioning protrusion 25 is provided with a through hole 251, one end of which extends through to the outer wall of the rear cover 2. The through hole 251 is used to insert heat insulation fasteners.

[0108] When using the wired controller in equipment such as a hot water heater, it is threaded onto the main body of the equipment by passing through the through hole 251 with an insulated fastener, so as to install the wired controller onto the main body of the equipment.

[0109] To improve the stability of the heat insulation board 5, the heat insulation board 5 is fixed to the inner wall of the back cover 2 with 3M adhesive strips, without affecting the subsequent disassembly and assembly of the heat insulation board 5.

[0110] In some embodiments, the wired controller also includes a decorative panel 6, which is attached to the front side of the front cover 1 to cover some holes on the front cover 1 and improve the aesthetics of the wired controller.

[0111] It should be noted that the wired controller provided in the embodiments of this utility model can be installed in water heaters, heating boilers, etc., and will not be listed one by one here.
