[0071] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0072] Heating, ventilation, and air conditioning (HVAC) systems are a crucial component of building environmental control, encompassing multiple systems such as heating, ventilation, and air conditioning. They are widely used in residential, commercial, and industrial buildings. Their primary function is to create a comfortable and healthy living and working environment by regulating parameters such as indoor temperature, humidity, and airflow. Common HVAC equipment includes air conditioners, radiators, and ventilation systems. These devices are widely used in residential, commercial, and industrial buildings.

[0073] Taking HVAC equipment as an example, an air conditioning system can be a multi-split system for buildings, that is, multiple indoor units are connected in parallel with one or more outdoor units to form a refrigerant circuit so that the refrigerant can circulate. Figure 1 A schematic diagram of the main structure of an outdoor unit in related technologies is shown. Combined with... Figure 1 The outdoor unit 10 has a body 110, which contains a compressor, switching valve, outdoor heat exchanger, outdoor expansion valve and oil separator, etc. These components are connected by refrigerant piping and cooperate with the components of the indoor unit to achieve refrigerant circulation and adjust the indoor temperature.

[0074] The body 110 is the external structure of the HVAC equipment, protecting internal components, providing a mounting base, and optimizing airflow. The body 110 can be made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance. The body 110 can be rectangular and placed on the roof or ground. The body 110 isolates internal live parts from the outside environment, preventing direct contact by users and thus reducing the occurrence of safety accidents such as electric shock.

[0075] Figure 2 A schematic diagram of the outdoor unit 10 is shown when the electronic control device 140 is exposed to the access port 1112. (Combined with...) Figure 2The outdoor unit 10 also includes an electrical control device 140, which is a core control component of the HVAC equipment. Installed inside the unit body 110, the electrical control device 140 facilitates maintenance and replacement, and also streamlines the installation and layout of the overall HVAC structure. The electrical control device 140 is responsible for precisely controlling the operation of the HVAC equipment. It contains various control circuits that use electronic components and wiring to control the HVAC equipment's start-up, stop, temperature adjustment, and mode switching.

[0076] Combination Figure 2 In some embodiments, the body 110 is provided with an access port 1112 and an openable access door 120. Maintenance personnel can open the access door 120 to expose the access port 1112 for maintenance and inspection of the electronic control device 140.

[0077] With the improvement of living standards, people have increasingly higher requirements for the intelligence of HVAC equipment. To this end, some HVAC equipment is equipped with a communication module to achieve linkage between the indoor unit and the outdoor unit 10. Specifically, the HVAC equipment includes an outdoor unit communication module installed on the outdoor unit 10 and an indoor unit communication module installed on the indoor unit. The outdoor unit communication module receives standby commands sent by the indoor unit communication module. The indoor unit communication module communicates with the outdoor unit communication module. Both the outdoor and indoor unit communication modules can be 4G, 5G, Bluetooth, or Wi-Fi modules. The outdoor unit communication module receives relevant commands (power on, standby, or power off, etc.) from the indoor unit communication module and generates corresponding instructions based on these standby commands. These instructions are then sent to the controller on the outdoor unit 10. The outdoor unit 10 acts according to the relevant instructions to achieve power on, standby, or power off, thereby executing the corresponding functions of the HVAC equipment.

[0078] In related technologies, the outdoor unit communication module is often installed inside the body 110 of the outdoor unit 10, or inside the electrical control cabinet of the electrical control device 140. When inspecting or maintaining the outdoor unit communication module, it is necessary to open the access door and / or the electrical control cabinet, allowing the user to perform maintenance or repairs inside the body 110. This operation requires the user to open the access port 1112 on the body 110 to open the electrical control cabinet of the electrical control device 140, or even to open the electrical control cabinet 140 itself, posing a technical problem of inconvenience in inspecting and maintaining the outdoor unit communication module.

[0079] Based on the aforementioned technical problems, this application provides an outdoor unit 10, in which the outdoor unit communication module is mounted on an externally exposed part of the outdoor unit 10. When the user maintains or repairs the outdoor unit communication module, they can directly maintain or repair the outdoor unit communication module without having to enter the unit body 110 to maintain or repair it, thus simplifying the maintenance procedure of the outdoor unit communication module and at least to some extent improving the technical problem of inconvenience in maintaining and repairing the outdoor unit communication module. For the sake of simplicity, the communication module referred to below refers to the outdoor unit communication module. The arrangement of the communication module in the outdoor unit 10 will now be further described with reference to the accompanying drawings.

[0080] Figure 3 A schematic diagram of the structure of the outdoor unit 10 in one or more embodiments of this application is shown. Figure 4 It shows Figure 3 A partial schematic diagram, Figure 5 It shows Figure 4 An enlarged view of point A. For clarity, Figure 4 Some components of the outdoor unit 10 have been omitted, retaining only the grille 114 and the communication module 130. Combined with... Figures 3-5 The outdoor unit 10 provided in this application includes a body 110 and a communication module 130. The body 110 has a maintenance section 111, and the maintenance section 111 is provided with an assembly part 1111. At least a portion of the assembly part 1111 is exposed outside the body 110. The communication module 130 is mounted on the portion of the assembly part 1111 that is exposed outside the body 110.

[0081] The outdoor unit 10 provided in this application has a maintenance section 111 in its body 110. The maintenance section 111 is provided with an assembly part 1111, at least a part of which is exposed to the outside of the body 110, that is, at least a part of which is directly exposed to the atmospheric environment. Since the communication module 130 is mounted on the part of the assembly part 1111 that is exposed to the outside of the body 110, when the user maintains and repairs the communication module 130, he / she can stand outside the body 110 and directly maintain and repair the communication module 130 without having to open the maintenance door 120 or the electrical control cabinet 140. This simplifies the maintenance and repair procedure of the communication module 130, improves the convenience and efficiency of maintenance and repair, and has good practicality.

[0082] It should be noted that the maintenance section 111 of this application may include other parts besides the assembly part 111, such as... Figure 2The inspection port 1112 shown is an example of this. Furthermore, at least a portion of the assembly part 1111 may be entirely exposed outside the body 110, or only partially exposed. Whether the assembly part 1111 is entirely or partially exposed outside the body 110, compared to solutions in related technologies, this improves the convenience and efficiency of maintenance and repair of the communication module 130.

[0083] In some embodiments, the mounting portion 1111 is disposed on the user-accessible side of the unit 110. Typically, the unit 110 has a top, a bottom, and a side. The top of the unit 110 protrudes from the outside of the unit 110, and the non-wall-facing side of the unit 110 also protrudes from the outside of the unit 110. The user-accessible side of the unit 110 can be the user-side surface of the unit 110, that is, when the outdoor unit 10 is used in a conventional installation posture, the plane containing the user-accessible side of the unit 110 faces the user. For the purposes of this application, the user-accessible side of the unit 110 is defined as the side of the unit 110, such as the side of the unit 110 facing away from the wall. The user-accessible side of the unit 110 is the front of the unit 110. When a user stands in front of the outdoor unit 10, the mounting portion 1111 faces the user, thereby allowing the user to easily and unobstructedly access the mounting portion 1111. The user can directly operate and maintain the communication module 130, improving the convenience and efficiency of the maintenance and repair of the communication module 130. For ease of description, the user-accessible side of the machine body 110 is now defined as the front, and the user-accessible side facing away from the machine body 110 is defined as the back.

[0084] In some embodiments, the height of the mounting portion 1111 relative to the bottom of the body 110 is adapted to the height of a human shoulder. This arrangement allows the user to perform ergonomic maintenance on the communication module 130, improving user comfort when operating the communication module 130. For example, the height of the mounting portion 1111 relative to the bottom of the body 110 is h1, which can be between 900mm and 1200mm (corresponding to the elbow-to-shoulder operating range for an adult user standing), conforming to the male shoulder height range in the "Anthropometric Dimensions of Chinese Adults" (GB / T 10000), enabling the user to perform maintenance on the communication module 130 in the optimal operating posture.

[0085] In some embodiments, the height of the body 110 is h2, where 0.5 ≤ h1 / h2 ≤ 0.8, for example: h1 / h2 = 2 / 3. Typically, the overall height of the body 110 is approximately 1.5m. This arrangement allows the height of the mounting part 1111 relative to the bottom of the body 110 to match the height of a human shoulder, enabling the user to maintain and repair the communication module 130 in the optimal operating posture, thus improving the user's comfort during communication module maintenance.

[0086] Since at least a portion of the assembly part 1111 protrudes outside the body 110, the communication module 130 is also located outside the body 110. Compared to a solution where the communication module 130 is housed within the body 110, the lack of protection from the body 110 makes the communication module 130 more susceptible to damage and moisture. Based on this, combined with... Figures 1-3 The housing 110 shown in this application also includes a frame 112 and a shielding part 113. The frame 112 houses components such as the unit that enable the outdoor unit 10 to operate. The shielding part 113 is connected to the frame 112, and the decorative part is located on the frame 112. At least a portion of the shielding part 113 protrudes from the mounting part 1111. This arrangement allows the shielding part 113 to shield the communication module 130 located on the decorative part, thereby preventing the communication module 130 from being directly exposed to rain, snow, dust, etc., which could cause damage or moisture, thus improving the service life of the communication module 130.

[0087] In one embodiment, the shield 113 is a protective cover connected to the top of the rack 112. The shield 113 protrudes from the rack 112 on the user-facing side to protect the communication module located on the rack 112. In another embodiment, the shield 113 can also be an eaves structure provided on the user-facing side of the rack 112, with the communication module 130 located below the shield 113, which can also achieve protection for the communication module 130. This application does not limit this aspect.

[0088] Combination Figures 3-5 In some embodiments, the body 110 further includes a grille 114 connected to the frame 112. The aforementioned access door 120 is provided on one side of the frame 112, and the grille 114 is connected to the other side of the frame 112. At least a portion of the grille 114 is configured as an assembly part 1111.

[0089] It should be noted that in some embodiments, the area of ​​the grille 114 is relatively large. For example, as shown in the figure, the area of ​​the grille 114 occupies approximately half of the side of the rack 112 facing the user, while the communication module 130 is relatively small. Therefore, the assembly part 1111 only needs to be located in a portion of the grille 114. In other embodiments, if the area of ​​the grille 114 is small, the entire grille 114 can be configured as the assembly part 1111. That is, in this application, the assembly part 1111 can be set in a suitable area of ​​the grille 114 according to the size of the grille 114, the communication module 130, and the grille 114 itself, for assembling the communication module 130.

[0090] Combination Figure 4 as well as Figure 5The grille 114 includes a frame 1141, first blades 1142, and connectors 1143. The first blades 1142 extend along a first direction, and both ends of the first blades 1142 are connected to the frame 1141. Multiple first blades 1142 are arranged at intervals along a second direction, with the second direction forming an angle with the first direction. The connectors 1143 connect at least two first blades 1142 and are configured as assembly parts 1111. In a specific implementation, when the outdoor unit 10 is in its installation position, the first blades 1142 extend horizontally, and multiple first blades 1142 are arranged at intervals vertically. The connectors 1143 connect adjacent first blades 1142 located above each other. Of course, if the communication module 130 is large, the connector 1143 can also be connected between three or more adjacent first blades 1142, or the connector 1143 can be connected between two non-adjacent first blades 1142 located above. For example, the connector 1143 can be connected between two first blades 1142 located in the first and third order above. The specific settings can be adjusted according to the size of the communication module 130, and this application does not impose any restrictions on this.

[0091] Combination Figure 4 as well as Figure 5 The grille 114 also includes a second blade 1144, which extends along a second direction (vertical). The two ends of the second blade 1144 are connected to the frame 1141. Multiple second blades 1144 are spaced apart along a first direction (horizontal) to enhance the overall strength of the grille 114 through multiple first blades 1142 and multiple second blades 1144, and to divide the grille 114 into multiple windows. The connector 1143 is located in one of the windows.

[0092] Figure 6 A schematic diagram of the assembly of connector 1143 on grille 114 is shown. Figure 6 The connector 1143 can be a sheet metal structure, with ear plates 1145 on both sides along the second direction (vertical). The ends of the ear plates 1145 away from the connector 1143 are adapted to overlap the back of the first blade 1142. The ear plates 1145 can be connected to the first blade 1142 by screws or welding. To strengthen the connection between the connector 1143 and the first blade 1142, at least two ear plates 1145 are connected to both sides of the connector 1143 in the second direction (vertical). In addition, the middle of the ear plates 1145 is bent, allowing the connector 1143 to be recessed into the grille 114. When the communication module 130 is assembled on the connector 1143, the communication module 130 is located within the grille 114. This arrangement protects the communication module 130 through the grille 114, improving the service life of the communication module 130.

[0093] In some embodiments, at least a portion of the cable configured for the communication module 130 is located on the side of the grille 114 facing the interior of the rack 112, that is, at least a portion of the cable is located on the back of the grille 114, for example, the cable may be located on the back of the first blade 1142. This arrangement allows the cable to be hidden through the grille 114, keeping the front of the rack 112 clean.

[0094] It should be noted that "at least part of the cable is located on the side of the grille 114 facing the inside of the rack 112" means that the entire cable is located on the side of the grille 114 facing the inside of the rack 112; it is also possible that due to the design of the grille 114 and / or the length of the cable, a part of the cable is located on the side of the grille 114 facing the inside of the rack 112, which can help keep the front of the rack 112 clean to a certain extent.

[0095] In some embodiments, the communication module 130 is detachably connected to the mounting portion 1111. This arrangement facilitates the installation and removal of the communication module 130 on the rack 112; if the communication module 130 needs to be replaced (e.g., for repair or upgrade), it can be quickly removed from the rack 112 and installed. The connection details between the communication module 130 and the mounting portion 1111 (i.e., the connector 1143) are now further described with reference to the accompanying drawings.

[0096] In some embodiments, the communication module 130 shown in this application is connected to the assembly part 1111 via a snap-fit ​​connection, which has the characteristics of quick installation, convenient disassembly, and reliable connection, and has good practicality.

[0097] Figure 7 An assembly diagram of the communication module 130 and the assembly part 111 is shown. Figure 8 It shows Figure 7 An explosion diagram. Figure 9 A schematic diagram of the communication module is shown. (Combined with...) Figures 7-9 At least a portion of the communication module 130 and at least a portion of the mounting portion 1111 are disposed opposite to each other. The side of the communication module 130 facing the mounting portion 1111 is defined as the first side 131, and the side of the mounting portion 1111 facing the communication module 130 is defined as the second side 11111. That is, the first side 131 is the back of the communication module 130, and the second side 11111 is the front of the communication module 130. One of the first side 131 and the second side 11111 is provided with a buckle 132, and the other is provided with a mounting hole 11112. The buckle 132 passes through the mounting hole 11112 so that the buckle 132 and one of them are located on both sides of the other, so that the communication module 130 can be snapped into the mounting portion 1111.

[0098] Combination Figures 7-9In some embodiments, when the communication module 130 is assembled to the assembly part 1111, the first side portion 131 and the second side portion 11111 are arranged opposite to each other. A buckle body 132 is provided on the first side portion 131, and a mounting hole 11112 is provided on the second side portion 11111. The buckle body 132 passes through the mounting hole 11112, so that the buckle body 132 and the first side portion 131 are located on opposite sides of the second side portion 11111. Since the assembly part 1111 is a plate-shaped connector 1143, when the communication module 130 is assembled, the buckle body 132 and the communication module 130 are respectively located on opposite sides of the assembly part 1111, thereby allowing the communication module 130 to snap into the assembly part 1111. This arrangement eliminates the need for holes in the first side portion 131, thus maintaining a sealed position for the communication module 130 and improving its waterproof and dustproof sealing performance. In other embodiments, mounting holes 11112 may be provided on the first side 131 and buckles 132 may be provided on the second side 11111. This application does not limit this.

[0099] Combination Figure 9 The buckle body 132 is connected to the first side 131, that is, the buckle body 132 is disposed on the first side 131. The side of the buckle body 132 facing the first side 131 forms an installation groove 133 with the first side 131. With the buckle body 132 passing through the installation hole 11112, by controlling the operation of the communication module 130, the buckle body 132 can move along the opening direction of the installation groove 133 to the side of the second side 11111 away from the first side 131, so that the second side 11111 is inserted into the installation groove 133. The buckle body 132 and the first side 131 are respectively located on both sides of the second side 11111, so that the communication module 130 and the assembly part 1111 can be snapped together. The operation is simple and quick. In specific implementation, the buckle body 132 can be integrally connected to the first side 131 through the connecting block 1321. The buckle body 132, the connecting block 1321 and the first side 131 form the installation groove 133. In other embodiments, the buckle body 132 may also be connected to the second side 11111, and the buckle body 132 and the second side 11111 form the above-mentioned mounting groove 133. The operation is similar to that described above, and will not be repeated here.

[0100] Combination Figure 9Multiple buckle bodies 132 are provided, and the openings of multiple mounting grooves 133 formed between the multiple buckle bodies 132 and the first side portion 131 or the second side portion 11111 face the same side. Correspondingly, multiple mounting holes 11112 are also provided, and the buckle bodies 132 and mounting holes 11112 are set one-to-one. When the buckle passes through the corresponding mounting hole 11112, the multiple buckle bodies 132 can be moved to the same side by controlling the communication module 130 to assemble the buckle body 132 into place. For example, two opposing fasteners 132 are provided on the first side portion 131 along the extension direction (horizontal direction) of the first blade 1142. The mounting groove 133 formed by the two fasteners 132 and the first side portion 131 is also opened along the extension direction (horizontal direction) of the first blade 1142. With the fasteners 132 passing through the corresponding mounting holes 11112, the communication module 130 can be moved along the extension direction (horizontal direction) of the first blade 1142, so that the communication module 130 can be assembled in place on the assembly part 1111. Since the assembly part 1111 (connector 1143) is located between two adjacent first blades 1142, the two adjacent first blades 1142 have sufficient space to facilitate the user's assembly of the communication module 130.

[0101] In other embodiments, the communication module 130 can also be directly connected to the assembly part 1111 by screws or other components, and this application does not limit this.

[0102] Figure 10 This shows a structural schematic diagram of the communication module 130 from another perspective. Figure 11 An exploded view of the communication module 130 is shown. (Combined with...) Figure 10 as well as Figure 11 To facilitate the inspection and maintenance of the communication module 130, the communication module 130 integrates a display screen 136 for displaying information about its internal components and / or operation buttons 137 for adjusting the information displayed on the display screen 137. Since the communication module 130 is externally located on the body 110, it lacks protection, and external objects (rain or dust) may damage the display screen 136 and / or operation buttons 137. Therefore, this application further improves the structure of the communication module 130 to extend its service life. The specific details of the communication module 130 are now described in further detail with reference to the accompanying drawings.

[0103] Combination Figure 10 as well as Figure 11 The communication module 130 includes a communication body 134 and a cover 135. The communication body 134 is connected to the assembly part 1111. The cover 135 is detachably connected to the communication body 134 and covers at least a portion of the communication body 134.

[0104] The communication module 130 provided in this application has a cover 135 that is detachably connected to the communication body 134 and covers at least a portion of the communication body 134. When the communication module 130 is assembled on the body 110 of the outdoor unit 10, the cover 135 can protect at least a portion of the communication body 134 from damage caused by external objects, thereby improving the service life of the communication module 130.

[0105] Combination Figures 7-11 In some embodiments, the aforementioned buckle 132 is disposed on the back of the communication body 134, and the communication body 134 is provided with a through mounting hole 1341, which penetrates the front and back of the communication body 134. The communication module 130 also includes a first locking member 138, at least a portion of which penetrates the mounting hole 1341 and connects to the mounting part 1111, thereby enabling the communication module 130 and the mounting part to be fixedly connected, preventing the communication module 130 from detaching from the mounting part 1111 due to external factors (such as wind).

[0106] In specific implementation, the communication body 134 is a shell structure, the mounting hole 1341 is a countersunk hole, and the first locking member 138 is a screw. The screw thread passes through the mounting hole 1341 and is locked in the connecting hole opened on the mounting part 1111. When the first locking member 138 is assembled in place, the first locking member 138 does not protrude from the front of the communication body 134, so that the front of the communication body 134 remains flat.

[0107] In addition, with the cover 135 covering at least a portion of the communication main body 134, the first locking member 138 is placed inside the cover 135, that is, the mounting hole 1341 is provided inside the cover 135. This arrangement allows the first locking member 138 to be hidden inside the cover 135, and the first locking member 138 cannot be seen from the outside of the communication module 130, thus ensuring the flatness of the appearance.

[0108] In some embodiments, the cover 135 is slidably connected to the communication body 134. That is, the cover 135 has a first state and a second state. When the outdoor unit 10 is operating normally, the communication module 130 is in a working state, and the cover 135 covers at least a portion of the communication body 134. The cover 135 is in the first state to protect at least a portion of the communication body 134. When the communication module 130 needs maintenance, the cover 135 slides away from the communication body 134 to expose the communication body 134 to the outside world, facilitating user maintenance. At this time, the cover 135 is in the second state. By switching between the first and second states, the cover 135 can adapt to the working state and maintenance state of the communication body 134.

[0109] Combination Figure 11 In some embodiments, the cover 135 is slidably connected to the communication body 134 along a height direction perpendicular to the frame 112, for example, the cover 135 slides along the extension direction of the first blade 1142. Since the communication module 130 is disposed between two adjacent first blades 1142, this arrangement allows the cover 135 to be operated using the space between the two adjacent first blades 1142. Because the cover 135 slides along the extension direction of the first blades 1142, the sliding of the cover 135 will not touch the first blades 1142, thus avoiding the first blades 1142 from obstructing the sliding of the cover 135, and facilitating user operation of the cover 135.

[0110] Combination Figure 11 In some embodiments, the communication body 134 includes a first body 1342 and a second body 1343. The first body 1342 and the second body 1343 are sequentially connected along the extension direction of the communication body 134. The projection of the second body 1343 is located within the first body 1342. A cover 135 is slidably disposed on the second body 1343 and can abut against the first body 1342. When the cover 135 is in a first state, it covers the second body 1343 to protect its outer surface. When the cover 135 is in a second state, it detaches from the second body 1343 to expose its outer surface, allowing the user to operate components on the outer surface of the second body 1343 for inspection and maintenance of the communication body 134.

[0111] In specific implementation, the part of the communication main body 134 covered by the cover 135 is provided with operation buttons 137, and the part of the communication main body 134 not covered by the cover 135 is provided with a display screen 136. For example, the first main body 1342 and the second main body 1343 are arranged sequentially along the extension direction (horizontal direction) of the first blade 1142. The side of the first main body 1342 facing the user can be provided with a display screen 136, the second main body 1343 is provided with the above-mentioned mounting hole 1341, and the side of the second main body 1343 facing the user is provided with operation buttons 137. When maintenance or repair of the communication main body 134 is required, the user operates the cover 135 to detach it from the second main body 1343. The cover 135 is in a second state, exposing the outer surface of the second main body 1343. The user operates the operation button 137. Simultaneously, the display screen 136 on the first main body 1342 displays various information about the communication module 130 in real time. The user determines whether the communication module 130 is malfunctioning based on the information displayed on the display screen 136. After the user completes the maintenance or repair of the communication main body 134, the user operates the cover 135 to cover the second main body 1343. The cover 135 is in a first state, protecting the outer surface of the second main body 1343. Since the operation button 137 protrudes from the second body 1343, it may cause the outer surface of the second body 1343 to be uneven. By covering the second body 1343 with the cover 135, the operation button 136 can be covered, making the outer surface of the communication module 130 flat, and protecting the operation button 137 to prevent dust and other impurities from entering the hole opened in the second body 1343 for mounting the operation button 137.

[0112] Combination Figure 11 The first body 1342 and the second body 1343 are arranged sequentially from left to right. When the user faces the communication module 130, the first body 1342 is located on the user's left and the second body 1343 is located on the user's right. Since the right hand is the dominant hand, this arrangement makes it easier for the user to operate the operation buttons 137 located on the second body 1343, thus improving the user experience.

[0113] Combination Figure 9 and Figure 11 The backs of the first main body 1342 and the second main body 1343 are located on the same plane, so that the back of the communication main body 134 is flush with it and can fit snugly with the mounting part 1111. The remaining sides of the first main body 1342 protrude from the remaining sides of the second main body 1343. With the cover 135 covering the second main body 1343 and abutting against the first main body 1342, the outer surface of the cover 135 is flush with the outer surface of the first main body 1342. This arrangement makes the outer surface of the communication module 130 completely flat, creating a simple appearance and enhancing visual continuity.

[0114] Figure 12 A structural schematic diagram of the cover 135 is shown. (Combined with...) Figure 12 The cover 135 is a U-shaped structure adapted to the second main body 1343. The end of the cover 135 facing the second main body 1343 and its back are open to prevent interference between the cover 135 and the latches on the back of the communication main body 134 when the cover 135 slides relative to the communication main body 134. The thickness of the cover 135 is consistent with the step difference between the remaining sides of the first main body 1342 and the remaining sides of the second main body 1343, so that when the cover 135 is in the second state, its outer surface is flush with the outer surface of the first main body 1342. Furthermore, the cover 135 can be made of plastic or metal to give it a certain degree of elasticity.

[0115] Figure 13 A schematic diagram of the communication unit 134 is shown. Figure 14 A cross-sectional schematic diagram of the communication module 130 is shown. (In conjunction with...) Figures 12-14 One of the second main body 1343 and the cover 135 is provided with a groove 13431, and the other is provided with a slide rail 1351, which slides within the groove 13431. The cooperation of the slide rail 1351 and the groove 13431 restricts the sliding direction of the cover 135, improving the ease of assembly and disassembly of the cover 135. Furthermore, the groove 13431 also helps to prevent the cover 135 from detaching from the second main body 1343, thus preventing the second main body 1343 from being left unprotected.

[0116] In specific implementation, the second main body 1343 is provided with sliding grooves 13431 on both sides (i.e., the top and bottom of the cover 135) along the height direction of the frame 112, and sliding rails 1351 are provided on the sides of the cover 135 that fit against the top and bottom of the second main body 1343. The sliding rails 1351 are slidably disposed in the corresponding sliding grooves 13431. In other embodiments, the above-mentioned sliding grooves 13431 may only be provided on one side of the second main body 1343 (the top or bottom of the cover 135), which can also achieve the technical effect of sliding guidance of the cover 135. This application does not limit this.

[0117] Combination Figure 13 The slide 13431 has a first end 13432 and a second end 13433. The first end 13432 of the slide 13431 is the end of the slide 13431 away from the first body 1342, and the second end 13433 of the slide 13431 is the end of the slide 13431 close to the first body 1342. The first end 13432 of the slide 13431 is open, thereby allowing the cover 135 to pass through... Figure 11The left side of the slide is pushed onto the second main body 1343. In addition, the two side walls of the first end 13432 of the slide groove 13431 are inclined, so that the opening of the end of the slide groove 13431 away from the first main body 1342 is funnel-shaped, thereby expanding the opening size of the first end 13432 of the slide groove 13431, so that the slide rail 1351 on the cover 135 can smoothly pass through the opening and enter the slide groove 13431, so as to facilitate the pushing of the cover 135.

[0118] Combination Figures 12-14 A first protrusion 13434 is provided in the groove 13431. The area between the first protrusion 13434 and the second end 13433 of the groove 13431 is defined as the first segment 13435. A third protrusion 1352 is provided on the slide rail 1351 corresponding to the groove 13431. The third protrusion 1352 can be provided at the end of the slide rail 1351. When the cover 135 is in the first state, the third protrusion 1352 is adapted to be embedded in the first segment 13435 of the groove 13431 to prevent the cover 135 from separating from the second body 1343 to a certain extent.

[0119] In specific implementation, the height of the first protrusion 13434 is lower than the depth of the groove 13431, so that when the slide rail 1351 is pushed, the slide rail 1351 always has a portion embedded in the groove 13431 to guide the sliding of the slide rail 1351. In addition, at least one side of the first protrusion 13434 and / or the third protrusion 1352 along the opening direction of the groove 13431 is inclined, so that when the slide rail 1351 is pushed, the third protrusion 1352 can be pushed smoothly along the groove 1352, ensuring the smoothness of the slide rail 1351 and avoiding the phenomenon of jamming during the sliding of the slide rail 1351.

[0120] Combination Figures 12-14 The slide groove 13431 is also provided with a second protrusion 13436, which is located on the side of the first protrusion 13434 away from the first body 1342. The area of ​​the slide groove 13431 between the second protrusion 13436 and the first protrusion 13434 is defined as the second segment 13437. The area of ​​the slide groove 13431 between the second protrusion 13436 and the second end 13433 of the slide groove 13431 is defined as the third segment 13438. The slide rail 1351 corresponding to the slide groove 13431 is provided with a fourth protrusion 1353. The fourth protrusion 1353 can be located at the other end of the slide rail 1351. When the cover 135 is in the first state, the fourth protrusion 1353 is embedded in the third segment 13438 of the slide groove 13431 to limit the pushing of the slide rail 1351, which indicates that the slide rail 1351 has been pushed into place.

[0121] In specific implementation, the height of the second protrusion 13436 is also lower than the depth of the groove 13431, so that when the slide rail 1351 is pushed, the slide rail 1351 always has a portion embedded in the groove 13431 to guide the sliding of the slide rail 1351. In addition, at least one side of the second protrusion 13436 along the opening direction of the groove 13431 is an inclined surface, so that when the slide rail 1351 is pushed, the third protrusion 1352 can smoothly pass over the second protrusion 13436 and be pushed in the direction of the first protrusion 13434, ensuring the smoothness of the slide rail 1351 and avoiding the phenomenon of jamming during the pushing of the slide rail 1351.

[0122] It should be noted that in other embodiments, the cover 135 can also cover at least a portion of the first main body 1342. For example, the cover 135 can cover the front, top, and bottom surfaces of the first main body 1342, thus achieving the same technical effect of protecting the communication main body 134. Alternatively, the communication main body 134 may not have operation buttons 137; a touch-screen display 136 can be used to display relevant data from the communication module 130 on the display screen 136.

[0123] In some embodiments, combined with Figure 10 The communication module also includes a second locking member 139, which is detachably connected to the cover 135 and the communication body 134. When the cover 135 covers at least part of the communication body 134, the cover 135 and the communication body 134 are locked together by the second locking member 139 to prevent the cover 135 from detaching from the communication body 134 due to external factors (such as wind).

[0124] Combination Figure 12 as well as Figure 13 In specific implementation, the end of the communication body 134 facing the cover 135 (the right end of the second body 1343 shown in the figure) is provided with a threaded hole 13439, and the end of the cover 135 is provided with a connecting hole 1354. The connecting hole 1354 and the threaded hole 13439 are arranged opposite to each other. The head of the second locking member 139 passes through the connecting hole 1354 and is threaded into the threaded hole 13439. The communication body 134 and the cover 135 can be locked by the second locking member 139 to prevent the cover 135 from detaching from the communication body 134 due to external factors (such as wind).

[0125] Combination Figure 12 as well as Figure 13Both the threaded hole 13439 and the connecting hole 1354 are inclined, and the central axis of both the threaded hole 13439 and the connecting hole 1354 are inclined toward the front of the communication body 134. This arrangement allows the disassembly direction of the second locking member 139 to be inclined toward the front of the communication body 134 (the side facing the user), thereby providing sufficient operating space to facilitate the user's disassembly of the second locking member 139 and thus improving the maintenance efficiency of the communication module.

[0126] When the user needs to maintain the communication module 130, the user operates the second locking member 139 to disconnect the connection between the communication body 134 and the cover 135. When assembling the cover 135 onto the communication body 134, the second locking member 139 needs to be reassembled onto both the cover 135 and the communication body 134. If the second locking member 139 is directly removed from the cover 135, there is a possibility of losing or searching for the second locking member 139, which to some extent reduces the assembly efficiency of the cover 135 and the communication body 134. Based on this, the second locking member 139 is movably connected to the cover 135. When the user needs to maintain the communication module 130, the user operates the second locking member 139 to disconnect the connection between the communication body 134 and the cover 135. However, the second locking member 139 is always located on the cover 135. When the cover 135 is assembled to the communication body 134, the second locking member 139 can be quickly assembled to the cover 135 and the communication body 134, thereby improving the assembly efficiency of the cover 135 and the communication body 134.

[0127] Figure 15 A schematic diagram of the assembly of the second locking member 139 into the cover 135 is shown. Figure 16 A schematic diagram of the second locking element 139 is shown. (Combined with...) Figure 15 as well as Figure 16 In specific implementation, the second locking member 139 is a screw structure. The nut 1391 of the second locking member 139 is located on the side of the cover 135 facing away from the communication body 134. The rod of the second locking member 139 is provided with a protrusion 1392, which is provided with threads. The protrusion 1392 is threaded into the threaded hole of the communication body 134. At least a portion of the gap between the protrusion and the nut is provided with a connecting hole 1354, so that the second locking member 139 can move on the cover 135 during the screwing in and out process, but will not disengage from the cover 135 due to the limiting of the protrusion 1392 and the nut 1391.

[0128] Since the communication module 130 provided in this application is externally mounted on the housing 110, it is inevitably subject to corrosion from rain, snow, dust, etc. Therefore, the sealing of the communication module 130 is particularly important. To facilitate the assembly of the internal components of the communication module 130, the outer shell of the communication module 130 needs to include at least two separate structures that can be joined together to form a shell. In related technologies, the separation between the separate structures is achieved through sealing elements. However, during actual assembly, the sealing elements may not be properly installed, causing them to deviate from their intended installation position. This results in poor sealing between the separate structures, consequently preventing the communication module 130 from being used for extended periods.

[0129] Based on the above-mentioned technical problems, this application further improves the communication module 130 to ensure the sealing effect of the communication module 130 and enable the communication module 130 to be used for a long time.

[0130] Figure 17 A schematic diagram of the communication body 134 of the communication module 130 is shown. Figure 18 It shows Figure 17 An explosion diagram. Figure 19 A top view of housing 1344 is shown. (Combined with...) Figures 17-19 The communication module 130 of this application includes a housing 1344, a cover 1345, a seal 1346, and a first limiting member 1347. The housing 1344 has an assembly opening 13441 and a first sealing groove 13442, with the first sealing groove 13442 surrounding the inner side of the assembly opening 13441. The cover 1345 is connected to the housing 1344 and detachably seals the assembly opening 13441. The seal 1346 is partially disposed within the first sealing groove 13442, and the other part protrudes from the opening side of the first sealing groove 13442 and abuts against the cover 1345. The first limiting member 1347 is connected to the housing 1344 and is disposed on at least one side of the width direction of the first sealing groove 13442.

[0131] The communication module 130 provided in this application has an assembly opening 13441 in the housing 1344, and a cover 1345 connected to the housing 1344 and detachably sealing the assembly opening 13441. Therefore, when assembling the communication module 130, the cover 1345 can be removed from the housing 1344, and after the communication module 130 is assembled, the cover 1345 can be assembled back onto the housing 1344 to seal the housing 1344. The housing 1344 has a first sealing groove 13442, which is located inside the assembly opening 13441, and a sealing element 1346 is partially disposed within the first sealing groove 13442. Inside, another part protrudes from the opening side of the first sealing groove 13442 and abuts against the cover 1345, thereby ensuring the sealing effect after the housing 1344 and the cover 1345 are assembled; since the first limiting member 1347 is connected to the housing 1344 and is provided on at least one side of the width direction of the first sealing groove 13442, the sealing member 1346 can be kept in the predetermined installation position by the setting of the first limiting member 1347, so as to avoid the phenomenon of the sealing member 1346 being misaligned due to improper assembly, thus ensuring the sealing effect between the housing 1344 and the cover 1345, and the communication module 130 can be used for a long time.

[0132] Figure 20 A partial schematic diagram of housing 1344 is shown, in conjunction with... Figure 20 The housing 1344 includes a peripheral side surface 13443 and a support portion 13444. One side of the peripheral side surface 13443 forms an assembly opening 13441. The support portion 13444 is connected to the inner side of the peripheral side surface 13443. A first sealing groove 13442 is formed on the side of the support portion 13444 facing the assembly opening 13441, and the opening side of the first sealing groove 13442 also faces the assembly opening 13441. In a specific implementation, the support portion 13444 includes a support plate 13441 and a first surrounding plate 13442. The support plate 13441 is integrally formed on the inner wall of the peripheral side surface 13443. The first surrounding plate 13442 is connected to the side of the support plate 13441 facing the assembly opening 13441. The first surrounding plate 13442, the support plate 13441, and the inner wall of the peripheral side surface 13443 together form the first sealing groove 13442. This configuration allows the inner wall of the peripheral side 13443 to form the first sealing groove 13442. While ensuring the first sealing groove 13442 has sufficient width, the width dimension of the support portion 13444 is reduced, thereby reducing the space occupied inside the housing 1344. In some embodiments, the first sealing groove 13442 can be a U-shaped groove to provide sufficient space inside for assembling the sealing element 1346, improving the stability of the sealing element 1346 within the first sealing groove 13442. In other embodiments, the first sealing groove 13442 can also be a V-shaped groove or a T-shaped groove; this application does not limit this.

[0133] Combination Figure 17 as well as Figure 18 The communication module 130 also includes a third locking member 1311. Multiple third locking members 1311 are provided. Multiple third locking members 1311 connect the cover 1345 and the support part 13444 so that the cover 1345 is fixedly connected to the housing 1344. Multiple third locking members 1311 are all provided between the first sealing groove 13442 and the peripheral side 13443.

[0134] Combination Figure 20 In some embodiments, the support portion 13444 further includes a plurality of second enclosure plates 13443, each corresponding to a third locking member 1311. The second enclosure plates 13443 are disposed on the side of the support plate 13441 facing the assembly port 13441, and connect to the peripheral side surface 13443. The area between the second enclosure plates 13443 and the peripheral side surface 13443 is used to install the third locking member 1311. The second enclosure plates 13443 are disposed between the first enclosure plate 13442 and the peripheral side surface 13443. The plurality of second enclosure plates 13443 and the peripheral side surface 13443 form the inner wall of the first sealing groove 13442. Since the third locking member 1311 is disposed between the first sealing groove 13442 and the peripheral side surface 13443, the third locking member 1311 also achieves the technical effect of restricting the position of the sealing member 1346.

[0135] Figure 21 A cross-sectional schematic diagram of seal 1346 is shown, in conjunction with... Figure 21 The sealing element 1346 includes a first portion 13461 and a second portion 13462 connected to each other. The first portion 13461 is adapted to be embedded in the first sealing groove 13442, and the second portion 13462 protrudes from the opening side of the first sealing groove 13442 and is flush with the inner side of the cover 1345. When the sealing element 1346 is assembled in the first sealing groove 13442, the outer sides of the first portion 13461 and the second portion 13462 are flush with each other so that the outer side of the sealing element 1346 fits against the inner wall of the peripheral side surface 13443 (excluding the position at the second enclosure 13443). The inner side of the second portion 13462 protrudes from the inner side of the first portion 13461 so that the second portion 13462 can overlap the first enclosure 13442 (the side wall of the first sealing groove 13442). This design prevents the second part 13462 of the seal 1346 from shrinking into the first sealing groove 13442 under cold conditions, thus avoiding a gap between the first enclosure 13442 and the housing 1344, which could cause the communication module 130 to lose its seal.

[0136] Combination Figure 20In some embodiments, the first limiting member 1347 is connected to the support portion 13444. Multiple first limiting members 1347 are provided, and each first limiting member 1347 is disposed between the first sealing groove 13442 and the peripheral side surface 13443; or / and, the first limiting member 1347 is disposed on the side of the first sealing groove 13442 away from the peripheral side surface 13443. That is, in some embodiments, the first limiting member 1347 may be provided only on one side of the first sealing groove 13442, or the first limiting member 1347 may be provided on both sides of the first sealing groove 13442, both of which can prevent the sealing member 1346 from loosening to a certain extent.

[0137] Combination Figure 20 The first limiting member 1347 includes at least one rib 13471, which is spaced apart and connected to the inner side of the support portion 13444. One end of the rib 13471 protrudes from the support portion 13444 towards the cover 1345 to restrict the inward movement of the sealing member 1346. In a specific implementation, multiple first limiting members 1347 are circumferentially spaced around the housing 1344 and arranged on the inner side of the support portion 13444. Each first limiting member 1347 includes two spaced ribs 13471. One end of the two ribs 13471 can be integrally formed and connected to the inner side of the peripheral side 13443, and the middle part of the two ribs 13471 can be integrally formed and connected to the inner side of the support portion 13444. The other end of the two ribs 13471 protrudes from the support portion 13444 to restrict the inward movement of the sealing member 1346. In other embodiments, the number of ribs 13471 included in each first limiting member 1347 may also be one, three, etc., and this application does not limit this.

[0138] Figure 22 A structural schematic diagram of the cover 1345 is shown. (Combined with...) Figure 21 The cover 1345 and the mounting opening 13441 are adapted to each other. When the cover 1345 is assembled into the mounting opening 13441, the cover 1345 and the peripheral side 13443 form one end of the mounting opening 13441, which are flush. A second sealing groove 13451 is provided on the side of the cover 1345 facing the housing 1344. The opening side of the second sealing groove 13451 is opposite to the opening side of the first sealing groove 13442. The sealing element 1346 has a portion disposed within the second sealing groove 13451. The second sealing groove 13451 can restrict the position of the sealing element 1346 to a certain extent to prevent the sealing element 1346 from loosening.

[0139] Figure 23 A partial schematic diagram of the cover 1345 is shown, in conjunction with... Figure 22 as well as Figure 23In some embodiments, the communication module 130 further includes a second limiting member 1348, which is connected to the cover 1345. One end of the second limiting member 1348 is located within the second sealing groove 13451, and the other end protrudes from the opening side of the second sealing groove 13451. This configuration restricts the movement of the seal 1346 while simultaneously compressing the seal 1346 to a certain extent, thus securing it between the support portion 13444 and the cover 1345 to prevent loosening. Specifically, the second limiting member 1348 is integrally formed into the bottom of the second sealing groove 13451, with its inner side flush with the inner wall of the second sealing groove 13451, thereby giving the second limiting member 1348 a portion located within the second sealing groove 13451.

[0140] In some embodiments, multiple second limiting members 1348 are provided, with at least some of the second limiting members 1348 inserted between two adjacent first limiting members 1347. This arrangement not only strengthens the housing 1344 through the first limiting members 1347 and strengthens the cover 1345 through the second limiting members 1348, but also provides guidance during the assembly of the cover 1345 with the housing 1344, demonstrating excellent practicality.

[0141] It should be noted that "at least some of the second limiting members 1348 are disposed between two adjacent first limiting members 1347" means that each second limiting member 1348 is disposed between two adjacent first limiting members 1347, or that only some of the second limiting members 1348 are disposed between two adjacent first limiting members 1347.

[0142] Combination Figure 19 as well as Figure 23 In some embodiments, at least a portion of the second limiting member 1348 has a locking hole 13481, and a buckle 1349 is provided on the inner wall of the peripheral side surface 13443. The buckle 1349 and the locking hole are provided in a one-to-one correspondence, and the buckle 1349 is engaged in the corresponding locking hole 13481. This arrangement not only uses the second limiting member 1348 to restrict the position of the sealing member 1346, but also allows the second limiting member 1348 to engage with the peripheral side surface 13443, improving the firmness of the assembly of the cover 1345 and the shell 1344. In specific implementation, at least a portion of the second limiting member 1348 protrudes from the support portion 13444, the locking hole 13481 is opened on the part of the second limiting member 1348 that protrudes from the support portion 13444, and the locking block is integrally formed and connected to the inner wall of the peripheral side surface 13443.

[0143] It should be noted that "at least some of the second limiting members 1348 have a locking hole 13481" means that each of the second limiting members 1348 has a locking hole 13481; or, only some of the second limiting members 1348 have a locking hole 13481. This application does not impose any restrictions on this.

[0144] As mentioned above, the communication module 130 integrates a display screen and operation buttons. How to ensure the sealing between the display screen and operation buttons and the housing 1344 while performing the corresponding functions is also a technical problem that needs to be solved.

[0145] Figure 24 A front view of housing 1344 is shown. (Combined) Figure 24 In some embodiments, the housing 1344 has a first mounting groove 13445. The bottom of the first mounting groove 13445 has a display opening 13446 and an adhesive groove 13447. The adhesive groove 13447 surrounds the display opening 13446 and is preferably located at the edge of the bottom of the first mounting groove 13445. The display screen 1310 is adapted to be bonded within the first mounting groove 13445. This bonding method not only allows the display screen 1310 to be mounted within the first mounting groove 13445, but also seals the connection between the display screen 1310 and the bottom of the first mounting groove 13445 using the adhesive, ensuring a tight seal between the display screen 1310 and the housing 1344. Furthermore, the adhesive can be contained within the adhesive groove 13447 to ensure the display screen is mounted as flatly as possible within the first mounting groove 13445.

[0146] Combination Figure 24 The housing 1344 also has a second mounting groove 13448, to which the operation button 1311 is bonded. This bonding method not only allows the operation button 1311 to be assembled within the second mounting groove 13448, but also ensures a seal between the operation button 1311 and the groove of the second mounting groove 13448 using the adhesive, thus guaranteeing a tight seal between the operation button 1311 and the housing 1344.

[0147] Combination Figure 24 In specific implementation, the first assembly slot 13445 and the second assembly slot 13448 are both opened on the side of the housing 1344 facing away from the cover 1345. That is, the first assembly slot 13445 and the second assembly slot 13448 are both arranged opposite to the cover 1345. The first assembly slot 13445 and the second assembly slot 13448 are both located on the front of the housing 1344, so that the display screen 1310 and the operation button 1311 are also located on the front of the housing 1344 for user convenience.

[0148] As described above, the communication module 130 is also equipped with a cable 1310, which needs to pass through the cover 1345 to connect with the corresponding components inside the machine. How to ensure the airtightness between the cable 1310 and the cover 1345 while the cable 1310 performs the corresponding function is also a technical problem that needs to be solved.

[0149] Figure 25 Another partial schematic diagram of the cover 1345 is shown. Figure 26 It shows Figure 25 A schematic diagram of the explosion. Combined with... Figure 25 as well as Figure 26 The cover 1345 has a cable mounting hole 13452. The communication module 130 also includes a cable sealing plate 1312 and a cable 1310. The cable sealing plate 1312 seals the cable mounting hole 13452 and is elastic. The cable 1310 is adapted to pass through the cable sealing plate 1312. With this configuration, while sealing the cable mounting hole 13452, the elasticity of the cable sealing plate 1312 allows it to press tightly against the periphery of the cable 1310, thereby ensuring that the cable 1310 passes through the cover 1345 in a sealed manner and ensuring the airtightness between the cable 1310 and the cover 1345.

[0150] Referring to the figures, in some embodiments, the cover 1345 has a cable mounting groove 13453 on the side facing the interior of the housing. The bottom of the cable mounting groove 13453 has a cable mounting hole 13452, and the side wall of the cable mounting groove 13453 has an injection hole 13454. A cable sealing plate 1312 is fitted through the cable mounting hole 13452, and a connecting flange 1313 is provided on the periphery of the cable sealing plate 1312. The connecting flange 1313 overlaps and adheres to the edge of the bottom of the cable mounting groove 13453. In specific implementations, adhesive can be injected through the injection hole 13454 between the connecting flange 1313 and the bottom of the cable mounting groove 13453 to seal the connection between the connecting flange 1313 and the bottom of the cable mounting groove 13453, thereby ensuring the airtightness between the cable sealing plate 1312 and the housing 1344.

[0151] As described above, the communication module 130 also has an assembly hole 1341 for installing the first locking member 138 on its communication body. Since the communication body 134 has an assembly hole 1341, how to ensure the sealing of the communication body 134 under the condition of having an assembly hole 1341 is also a technical problem that needs to be solved.

[0152] Figure 27 It shows Figure 19 A schematic diagram of the AA cross-section. Combined with... Figure 27The housing 1344 has a first through hole 13449, and the cover 1345 has a second through hole 13455. The second through hole 13455 and the first through hole 13449 are arranged opposite to each other. The communication module 130 also includes a first connecting sleeve 1314, a support member 1315, and a filler member 1316. One end of the first connecting sleeve 1314 is connected to one of the housing 1344 and the cover 1345, and the other end of the first connecting sleeve 1314 abuts against the other. The first through hole 13449 is connected to the second through hole 13455 through the first connecting sleeve 1314. The support member 1315 is connected to the first connecting sleeve 1314 and is placed inside the first connecting sleeve 1314. A third through hole 13151 is opened in the middle of the support member 1315. The filler member 1316 is disposed between the support member 1315 and the cover 1345 and surrounds the inner side of the first connecting sleeve 1314. The housing 1344, cover 1345, first connecting sleeve 1314, support member 1315, and filler 1316 enclose and form the aforementioned assembly hole. Due to the first connecting sleeve 1314, the area where the first locking member 138 is located is independent, ensuring the internal sealing of the communication body. Furthermore, the filler 1316 is made of a flexible material, ensuring the seal between the first locking member 138 and the first connecting sleeve 1314, thereby guaranteeing the sealing of the communication body. In one embodiment, the first connecting sleeve 1314 and housing 1344 are integrally formed, with the first connecting sleeve 1314 abutting against the cover 1345. In other embodiments, the first connecting sleeve 1314 and cover 1345 are integrally formed, with the first connecting sleeve 1314 abutting against the housing 1344.

[0153] Combination Figure 26 The communication module 130 also includes a second connecting sleeve 1317, which is built into the first connecting sleeve 1314. One end of the second connecting sleeve 1317 is connected to the cover 1345, and the other end abuts against the support member 1315. The second through hole 13455 and the third through hole 13151 are connected through the second connecting sleeve 1317. A filler 1316 is disposed between the second connecting sleeve 1317 and the first connecting sleeve 1314. This arrangement ensures that the communication module 130 is located between the second connecting sleeve 1317 and the first connecting sleeve 1314 when it is not assembled, thus guaranteeing that the communication module 130 is in a sealed environment when it is not assembled.

[0154] Figure 28 A structural schematic diagram of filler 1316 is shown. (Combined with...) Figure 27The filler 1316 has multiple sealing protrusions 1318 on the side facing the first connecting sleeve 1314. This arrangement improves the sealing effect between the filler 1316 and the first connecting sleeve 1314, further ensuring the airtightness of the communication device. In specific implementations, the sealing protrusions 1318 are annular or spiral in shape, and the sealing protrusions 1318 and the filler 1316 are integrally formed.

[0155] In summary, this application provides a communication module 130 that provides at least partial protection for the communication body 134 through a cover 135 that can slide relative to the communication body 134. Furthermore, through the aforementioned sealing arrangement, the sealing performance of the communication body 134 can be guaranteed, thereby improving the service life of the communication body 134 and demonstrating excellent practicality.

[0156] In a second aspect, this application also provides a heating, ventilation, and air conditioning (HVAC) device, which includes an indoor unit and the aforementioned outdoor unit 10.
