For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The implementation methods of the present application are described in detail below with reference to the accompanying drawings.

[0031] Reference Figures 1 to 3 According to the embodiment of the present application, the communication module 100 includes a module housing 10 and a control board 20 .

[0032] The module housing 10 may be in the shape of a rectangular parallelepiped box. The control board 20 is installed in the module housing 10 .

[0033] The module housing 10 includes a housing body 11. The housing body 11 forms the general structure of the module housing 10. The outer surface of the housing body 11 includes four side surfaces and a first mounting surface 111 connected to one end of the four side surfaces. One of the four side surfaces is a reference surface 115, and the side surface opposite to the reference surface 115 is a second mounting surface 112.

[0034] Combination Figure 2 and Figure 4 The module housing 10 includes a buckle 12 . The buckle 12 is connected to the first mounting surface 111 .

[0035] The buckle 12 includes a root portion 121 and a clamping portion 122. The root portion 121 is formed by extending outward from the first mounting surface 111. The clamping portion 122 is connected to the root portion 121, and there is a spacing between the clamping portion 122 and the first mounting surface 111, and the spacing forms a clamping groove.

[0036] The root portion 121 is connected between the first mounting surface 111 and the clamping portion 122 , so that a space is formed therebetween.

[0037] Reference Figure 5 and Figure 6 The communication module 100 can be installed on a mounting plate 200 in the air conditioner for use. The mounting plate 200 is mostly in the shape of a thin plate, and a through card slot 210 is provided on it.

[0038] During assembly, the buckle 12 is inserted into the corresponding slot 210 , and then the mobile communication module 100 is moved so that the buckle 12 is clamped on the mounting plate 200 .

[0039] The module housing 10 includes an extension portion 13. The extension portion 13 is connected to the side surface excluding the reference surface 115. The extension portion 13 is provided with a first mounting hole 131.

[0040] The mounting plate 200 is provided with a second mounting hole 220. In the assembled state, the second mounting hole 220 corresponds to the first mounting hole 131. The communication module 100 can be fastened to the mounting plate 200 by penetrating the first mounting hole 131 and the second mounting hole 220 with fasteners such as screws or bolts.

[0041] In the embodiment provided in the present application, a clip 12 and a first mounting hole 131 are provided on the module housing 10 of the communication module 100. The communication module 100 is fixedly installed by combining the clip 12 and screws, which can reduce the use of screws and improve the efficiency of disassembly and assembly. In some occasions with limited space, only one screw needs to be tightened, which also improves the convenience of disassembly and assembly.

[0042] In some embodiments, reference Figure 6 The buckle 12 is close to the reference surface 115 , and the clamping portion 122 extends from the root portion 121 toward the direction close to the reference surface 115 .

[0043] Since the buckle 12 is close to the reference surface 115 and the clamping opening end of the buckle 12 (the end away from the root) is facing the reference surface 115, the communication module 100 can be installed in an inclined manner, that is, the first mounting surface 111 of the communication module 100 is inclined relative to the mounting plate 200, and the end where the reference surface 115 is located is close to the mounting plate 200, and the end where the second mounting surface 112 is located is away from the mounting plate 200. Then, after the buckle 12 is clamped to the mounting plate 200 from the slot 210, the end where the reference surface 115 is located is used as a fulcrum to rotate the second mounting surface 112 end of the communication module 100 in a direction close to the mounting plate 200.

[0044] In the embodiment provided in the present application, by setting the buckle 12 close to the end of the module housing 10 (close to the reference surface 115) and clamping the open end toward the reference surface 115, the buckle 12 can be inserted into the slot 210 in an inclined manner, thus facilitating the operation of on-site personnel.

[0045] In addition, since the buckle 12 can be inserted into the slot 210 in an inclined manner, the length d2 of the slot 210 can be smaller than the length d1 of the buckle 12, thereby avoiding the problem that the length of the slot 210 is greater than the length of the buckle 12 when the buckle 12 is directly inserted into the slot 210, resulting in the slot 210 being too long. The present application reduces the area of ​​the slot 210 and can improve the strength of the mounting plate 200.

[0046] The free end of the clamping portion 122 , ie, the end away from the root portion 121 , does not protrude beyond the reference surface 115 in the extending direction of the clamping portion 122 .

[0047] In some embodiments, the extension 13 is connected to the second mounting surface 112, and the extension 13 is opposite to the buckle 12. For example, the extension 13 and the buckle 12 may be located in the middle of the length direction of the shell body 11. Fixing the communication module 100 from the middle can reduce the connection structure and ensure the firmness of the connection.

[0048] In some embodiments, the module housing 10 includes a positioning column 14. The positioning column 14 is formed by protruding outward from the first mounting surface 111. Accordingly, a positioning hole 230 is provided on the mounting plate 200.

[0049] The positioning column 14 is located between the buckle 12 and the extension 13. The distance between the positioning column 14 and the extension 13 is smaller than the distance between the positioning column 14 and the buckle 12, that is, the positioning column 14 is closer to the extension 13.

[0050] In the present application, the communication module 100 can be installed and positioned by providing the buckle 12 and the positioning column 14. The installation is smooth by positioning first and then fixing, which is convenient for the operation of the on-site personnel.

[0051] The positioning post 14 may be disposed adjacent to the extension portion 13 , so that after the positioning post 14 is inserted into the positioning hole 230 of the mounting plate 200 , the first mounting hole 131 and the second mounting hole 220 may be accurately aligned.

[0052] According to an embodiment of the present application, the buckle 12 and the extension portion 13 are located at both ends of the shell body 11 in the width direction. The width direction of the buckle 12 is parallel to the length direction of the shell body 11.

[0053] If the width of the buckle 12 is relatively small, a positioning straight line is formed between the two positioning points of the buckle 12 and the positioning column 14. Due to the existence of the matching clearance at the positioning points, the positioning straight line may deviate from the ideal position, thereby causing the first mounting hole 131 and the second mounting hole 220 to be misaligned, that is, the positioning is not accurate enough.

[0054] Therefore, in the present application, the width of the buckle 12 is set to be greater than twice the diameter of the positioning column 14, so that a triangular positioning is formed between the buckle 12 and the positioning column 14, and the width direction of the buckle 12 forms one side of the triangle. Compared with the straight line positioning, the triangular positioning is not easy to deviate from the ideal position, thereby improving the positioning accuracy of the communication module 100.

[0055] The extension portion 13 may be triangular in shape, and the area of ​​the extension portion 13 is reduced as much as possible while ensuring the connection strength between the extension portion 13 and the shell body 11 , thereby reducing the effect of the extension portion 13 on the increase in the volume of the communication module 100 .

[0056] During the installation of the communication module 100, the first mounting surface 111 of the communication module 100 is oriented toward the mounting plate 200, and the communication module 100 is close to the mounting plate 200 in a tilted state relative to the mounting plate 200, that is, the end where the buckle 12 of the communication module 10 is located is aligned with the slot 210 of the mounting plate 200, so that the buckle 12 is inserted into the slot 210, and then the end where the buckle 12 is located is used as a fulcrum to rotate the end where the extension portion 13 of the communication module 100 toward the mounting plate 200, so that the positioning column 14 is inserted into the positioning hole 230, thereby realizing the installation positioning of the communication module 100. After the first mounting surface 111 of the communication module 100 abuts against the mounting plate 200, the screws are screwed into the first mounting hole 131 and the second mounting hole 220.

[0057] In some embodiments, reference Figure 4 The buckle 12 has a stepped structure. The inner surface of the clamping portion 122 facing the first mounting surface 111 is stepped to adapt to mounting plates 200 of different thicknesses.

[0058] Since the communication module 100 in the present application is fixed to the mounting plate 200 by combining a buckle 12 and a screw, if the mounting plate 200 is relatively thin, the matching clearance between the buckle 12 and the mounting plate 200 will be relatively large, and the communication module 100 may easily shake, resulting in the communication module 100 being installed loosely.

[0059] Therefore, the embodiment provided in the present application adopts a stepped buckle, which can adapt to mounting plates 200 of different thicknesses, reduce the gap between the buckle 12 and the mounting plate 200, and ensure the installation firmness of the communication module 100.

[0060] The inner surface of the clamping portion 122 has at least two stepped surfaces. Take the buckle 12 having two stepped surfaces as an example for description: the two stepped surfaces are a first stepped surface 1221 and a second stepped surface 1222. The first stepped surface 1221 is closer to the root 121 than the second stepped surface 1222.

[0061] The space between the first step surface 1221 and the first mounting surface 111 forms a first clamping groove 1231, and the space between the second step surface 1222 and the first mounting surface 111 forms a second clamping groove 1232. The clamping width of the first clamping groove 1231 is smaller than that of the second clamping groove 1232.

[0062] When the thickness of the mounting plate 200 is relatively thin, the first clamping groove 1231 of the buckle 12 can be adapted to the mounting plate 200, that is, the mounting plate 200 is clamped at the first clamping groove 1231 of the buckle 12; when the thickness of the mounting plate 200 is relatively thick, the second clamping groove 1231 of the buckle 12 can be adapted to the mounting plate 200, that is, the mounting plate 200 is clamped at the second clamping groove 1232 of the buckle 12.

[0063] For example, refer to Figure 7 and Figure 8 , the width of the first clamping groove 1231 is 0.9 mm, and the width of the second clamping groove 1232 is 1.1 mm.

[0064] When the thickness of the mounting plate 200 satisfies: 0.6mm≤thickness≤0.8mm, the mounting plate 200 is inserted into the first clamping groove 1231. Since the width of the first clamping groove 1231 is 0.9mm, a small gap can be maintained between the buckle 12 and the mounting plate 200 to prevent the communication module 100 from shaking after installation.

[0065] When the thickness of the mounting plate 200 satisfies: 0.8mm<thickness≤1.0mm, the mounting plate 200 is inserted into the second clamping groove 1232. Since the width of the second clamping groove 1232 is 1.1mm, a small gap can be maintained between the buckle 12 and the mounting plate 200 to prevent the communication module 100 from shaking after installation.

[0066] The stepped buckle 12 of the present application can be adapted to a mounting plate 200 with a thickness of 0.6 mm to 1.0 mm, thereby expanding the adaptability range of the mounting plate 200 and ensuring a small clearance fit between the buckle 12 and the mounting plate 200 .

[0067] In some embodiments, reference Fig. 9 The shell body 11 includes a base 113 and an upper cover 114. The base 113 and the upper cover 114 are buckled and connected together.

[0068] The base 113 is in the shape of a box with an open top; the upper cover 114 is in the shape of a box with an open bottom. The base 113 and the upper cover 114 can be connected by a buckle. A plurality of slots are provided at intervals on the upper end surface of the base 113; correspondingly, buckles are provided on the inner side wall of the upper cover 114. When the upper cover 114 is buckled onto the base 113, the buckles are snapped into the slots.

[0069] The buckle 12 , the positioning column 14 , and the extension portion 13 may be disposed at the bottom of the base 113 .

[0070] The communication module 100 includes a control board 20, and electrical components are connected to the control board 20. The control board 20 can be connected to the upper end of the base 113. Specifically, a support platform is provided at the inner side wall of the base 113, and the control board 20 abuts against the support platform.

[0071] In some embodiments, a first support column 1131 protruding upward is disposed at the center of the base 113 , and the control board 20 abuts against the top of the first support column 1131 .

[0072] The support platform supports the edge of the control board 20 , and the first support column 1131 supports the middle of the control board 20 .

[0073] In some embodiments, a second support column 1141 protruding downward is disposed in the upper cover 114 . The second support column 1141 abuts against the top surface of the control board 20 .

[0074] The second support column 1141 is opposite to the first support column 1131. The control board 20 is sandwiched between the first support column 1131 and the second support column 1141.

[0075] Fasteners such as screws are sequentially passed through the first support column 1131 , the control board 20 and the second support column 1141 are screwed together.

[0076] In the embodiment provided in the present application, screws are passed through the first support column 1131 , the control board 20 , and the second support column 1141 , which can not only fasten the upper cover 114 and the base 113 together, but also fasten the control board 20 .

[0077] In some embodiments, reference Fig.10 and Fig.11 The communication module 100 includes a transformer board 30 for realizing high and low voltage conversion.

[0078] The base 113 is divided into two chambers by a partition 1132, namely a first chamber 1133 and a second chamber 1134. The control board 20 is installed in the first chamber 1133, and the transformer board 30 is installed in the second chamber 1134. Placing the control board 20 and the transformer board 30 in two chambers can improve the insulation between the two.

[0079] The transformer board 30 is fixed in the second cavity 1134 by injecting glue into the second cavity 1134 .

[0080] In some embodiments, two ribs 1135 are respectively disposed on two opposite side walls of the second cavity 1134 , and a spacing between the two ribs 1135 forms a positioning groove 1136 .

[0081] The transformer board 30 is inserted into the positioning groove 1136 to achieve installation and positioning of the transformer board 30 in the base 113 .

[0082] The width of the positioning groove 1136 may be no greater than the thickness of the transformer plate 30 , so that an interference fit is formed between the transformer plate 30 and the positioning groove 1136 , thereby ensuring the firmness of the transformer plate 30 and preventing the transformer plate 30 from moving during subsequent glue injection.

[0083] After the transformer board 30 is inserted into the positioning groove 1136 , insulating glue is poured into the second cavity 1134 , and the height of the glue is higher than the transformer board 30 , so that the transformer board 30 meets the insulation requirements in the smallest space.

[0084] In some embodiments, there are strong and weak electric wire harnesses between the transformer board 30 and the control board 20. A strong electric wire trough 1137 and a weak electric wire trough 1138 are provided at the upper end of the partition 1132 between the first cavity 1133 and the second cavity 1134. The strong electric wire trough 1137 is used for routing the strong electric wire harness, and the weak electric wire trough 1138 is used for routing the weak electric wire harness.

[0085] The embodiments provided in the present application can not only meet the requirements of wiring harness fixation and prevent wire clamping during the buckling process of the upper cover 114 and the base 113 through different wire groove designs, but also achieve the separation of weak current and strong current.

[0086] In another aspect of the present application, an air conditioner is provided, wherein a mounting plate 200 is provided inside the air conditioner, and the communication module 100 is connected to the mounting plate 20 .

[0087] The mounting plate 200 may be a panel of the air conditioner, or the mounting plate 200 may be disposed in an electrical box of the air conditioner.

[0088] In the air conditioner of the present application, the communication module 100 is fixed by combining a clip 12 and a screw, which facilitates the disassembly and assembly operations; at the same time, the clip 12 adopts a stepped structure, and the thickness range of the adaptable mounting plate 200 is relatively large, so that the communication module 100 is universal and can be installed on any air conditioner.

[0089] In the present application, a buckle 12 and an extension portion 13 with a screw mounting hole are provided on the outer surface of the communication module 100, and the communication module 100 is fixedly connected to the mounting plate 200 by combining the buckle connection and the screw connection. Since the number of screws is relatively small, the disassembly and assembly efficiency and the operational convenience can be improved; the buckle 12 adopts a stepped structure, which can expand the thickness range of the adapted mounting plate. While improving the versatility, the gap between the buckle 12 and the mounting plate 200 will not be too large, thereby improving the connection firmness of the communication module 100.

[0090] In the present application, the buckle 12 is located on one end of the first mounting surface 111 close to the reference surface 115, and the clamping opening end of the buckle 12 faces the reference surface 115, so that the buckle 12 can be inserted into the slot 210 in an inclined manner, which facilitates the operation of on-site personnel.

[0091] In the present application, since the buckle 12 can be inserted into the slot 210 in an inclined manner, the length d2 of the slot 210 can be smaller than the length d1 of the buckle 12 , thereby reducing the area of ​​the slot 210 and improving the strength of the mounting plate 200 .

[0092] In the present application, the width of the buckle 12 is greater than twice the diameter of the positioning column 14. The limiting effect between the buckle 12 and the slot 210 can avoid the problem of inaccurate positioning of the communication module 100 during installation, and ensure the accuracy of the positioning of the communication module 100 in a direction parallel to the mounting plate 200.

[0093] In the present application, a first support column 1131 for supporting the control board 20 is arranged on the base 113, and a second support column 1131 for pressing the control board 20 is arranged on the upper cover 114. Screws are passed through the first support column 1131, the control board 20 and the second support column 1141, which can not only fasten the upper cover 114 and the base 113 together, but also play the role of fastening the control board 20.

[0094] In the present application, a first cavity 1133 and a second cavity 1134 separated from each other are provided on the base 113, a control board 20 is installed in the first cavity 1133, and the transformer board 30 is fixed in the second cavity 1134 by means of glue injection, which can increase insulation and reduce the module size while meeting the insulation performance requirements.

[0095] In the present application, the second cavity 1134 is provided with a rib sheet 1135, and the positioning groove 1136 between the transformer plate 30 and the rib sheet 1135 is interference fit, which can firmly fix the transformer plate 30 and prevent the transformer plate 30 from shaking or dislocating during the glue injection process.
