Description

Technical Field

[0001] This utility model relates to the field of communication module installation technology, and in particular to an installation structure and a cabinet-type air handling unit. Background Technology

[0002] Currently, in cabinet-type air handling units, communication modules are commonly installed on the front panel using a multi-screw fastening method. This method requires pre-positioning the module to ensure precise alignment of the screw holes with the screw posts on the equipment before tightening each screw individually. This cumbersome process and difficult alignment significantly increase assembly time and impact production efficiency. Additionally, some products use a multi-claw plug-in fixing method. While this is more convenient during installation, requiring no tools, it presents significant challenges during after-sales service. If the communication module malfunctions and needs replacement or repair, disassembly is often extremely difficult. Because the claw structure is typically designed for one-way locking or is prone to brittle fracture, non-professional disassembly can easily damage the claws, even affecting the equipment's structure, resulting in higher maintenance costs.

[0003] Therefore, designing a fixing scheme that enables both rapid and reliable installation and easy, non-destructive disassembly of communication modules has become a key challenge for improving product assembly efficiency and after-sales maintenance experience, and is also a practical problem that the industry urgently needs to solve. Utility Model Content

[0004] This utility model provides an installation structure and a cabinet-type air handling unit to solve the defects of low assembly efficiency and high maintenance cost of communication modules in existing cabinet-type air handling units. It enables fast and reliable installation of communication modules and facilitates non-destructive disassembly of communication modules in the future, thereby improving product assembly efficiency and after-sales maintenance experience.

[0005] The first aspect of this utility model provides an installation structure, including: Mounting base; The first limiting member and the second limiting member are both installed on the mounting base; the first limiting member and the second limiting member are arranged at intervals along the first direction; the first limiting member and the second limiting member are respectively used to abut against the two end faces of the communication module; At least two second limiting components are mounted on the mounting base; the at least two second limiting components are arranged at intervals along a second direction; the second direction intersects the first direction; The second limiting component has a limiting groove along the first direction, and the limiting groove has an assembly opening; the assembly opening is used for the fixing piece on the side of the communication module to enter and exit the limiting groove, and the limiting groove is used for limiting assembly with the fixing piece.

[0006] According to the installation structure provided by this utility model, the second limiting component includes: The support frame includes a first support plate and a second support plate, both mounted on the mounting base; the first support plate and the second support plate are arranged along the second direction. The third limiting plate is located on the side of the first support plate and the second support plate away from the mounting base. The third limiting plate is connected to the first support plate and the second support plate, and together with the side of the first support plate away from the mounting base, they enclose the limiting groove having the assembly opening.

[0007] According to the installation structure provided by this utility model, the end of the third limiting plate facing the first limiting member forms a limiting guide angle.

[0008] According to the installation structure provided by this utility model, the draft angle of the third limiting plate toward the limiting surface of the mounting base is 3°~10°.

[0009] According to the installation structure provided by this utility model, it also includes: The first reinforcing rib is installed on the mounting base; the first reinforcing rib is connected to the support frame.

[0010] According to the installation structure provided by this utility model, a guide component is also included, the guide component comprising: Two guide members are installed on the mounting base; the two ends of the second limiting member are respectively connected to one end of the two guide members, and the other ends of the two guide members extend along the first direction. The guide members are used to abut against the side of the communication module.

[0011] According to the installation structure provided by this utility model, the side of the first limiting member away from the mounting base has a disassembly and assembly guide surface.

[0012] According to the installation structure provided by this utility model, it also includes: The second reinforcing rib is installed on the mounting base; the second reinforcing rib is installed on the side of the first limiting member away from the second limiting member.

[0013] According to the installation structure provided by this utility model, it also includes: A support component is disposed between the first limiting member and the second limiting member to support the communication module.

[0014] A second aspect of this utility model provides a cabinet-type air handling unit, including a housing and an installation structure as described in any of the above claims; the installation structure is installed on the housing.

[0015] The installation structure provided by this utility model eliminates the need for precise positioning during the installation of the communication module, enabling "blind operation." During the advancement process, the fixing piece slides along the limiting groove to the bottom, automatically completing precise positioning. This process requires no tools and eliminates the need to align multiple screw holes, significantly reducing operational difficulty and time consumption, greatly improving production line assembly efficiency, and reducing worker labor intensity. The structure of the limiting groove naturally constrains and guides the movement path of the fixing piece, acting like a "track" to ensure that even if the communication module is initially slightly off-center, it can automatically correct itself to the designed position during advancement, preventing installation misalignment. After the communication module is pushed into place, its two end faces tightly abut against the first and second limiting members, respectively. These two limiting members together eliminate the lateral force of vibration and handling along the installation direction (i.e., the first direction) of the communication module. The fixing pieces on the sides of the communication module are enclosed in their respective limiting grooves. The bottom of the limiting groove abuts against the end face of the fixing plate to prevent the module from loosening; the inner wall of the limiting groove abuts against the side of the fixing plate, effectively limiting the module's lateral swaying and twisting in the horizontal plane and its vertical displacement. The first limiting member, the second limiting member, and the limiting groove work together to limit the communication module from three directions, ensuring the stability of the communication module's installation.

[0016] The communication module can be disassembled without the need for any special tools or professional skills, which reduces the difficulty of disassembly and increases the speed of disassembly.

[0017] The installation structure of this utility model can achieve fast and reliable installation of the communication module and facilitate non-destructive disassembly in the later stage. It can improve product assembly efficiency and after-sales maintenance experience, and solve the defects of low assembly efficiency and high maintenance cost of communication module in cabinet-type air handling equipment in the prior art.

[0036] It should be noted that the mounting structure provided by this utility model can be used to install communication modules, such as mounting communication modules on the casing of cabinet-type air handling equipment, and can also be used to install electrical control boxes, etc. The specific embodiments of this utility model do not limit the application scenarios of the mounting structure.

[0037] The following is combined with Figures 1 to 9 Taking the installation of a communication module as an example, the installation structure of this utility model will be described.

[0038] like Figures 1 to 4 As shown, a specific embodiment of the first aspect of this utility model provides an installation structure 100. The installation structure 100 includes a mounting base 110, a first limiting member 121, a second limiting member 122, and at least two second limiting components 130.

[0039] The first limiting member 121 and the second limiting member 122 are both installed on the mounting base 110; the first limiting member 121 and the second limiting member 122 are arranged at intervals along the first direction; the first limiting member 121 and the second limiting member 122 are respectively used to abut against the two end faces of the communication module 300.

[0040] The second limiting component 130 is mounted on the mounting base 110; at least two second limiting components 130 are arranged at intervals on both sides of the second limiting member 122 along a second direction, the second direction intersecting the first direction. A limiting groove 131 is formed on the second limiting component 130 along the first direction, and the limiting groove 131 has an assembly opening 132; the assembly opening 132 is used for the fixing piece 310 on the side of the communication module 300 to enter and exit the limiting groove 131, and the limiting groove 131 is used for limiting assembly with the fixing piece 310.

[0041] The current communication module 300 is usually equipped with fixing plates 310 on both sides. The fixing plates 310 have threaded holes, and the communication module 300 can be fixedly installed by screws and nuts.

[0042] In this embodiment, the communication module 300 can be quickly installed and removed without changing its existing structure. Specifically: The communication module 300 is pushed into the space between the first limiting member 121 and the second limiting member 122 along the first direction. As the pushing process proceeds, the fixing piece 310 enters the limiting groove 131 from the assembly opening 132, and then enters the limiting groove 131 under the guidance of the limiting groove 131 until the end face of the fixing piece 310 away from the first limiting member 121 abuts against the bottom of the limiting groove 131, indicating that the assembly is in place. At the same time, both ends of the communication module 300 abut against the first limiting member 121 and the second limiting member 122 respectively, and the inner side wall of the limiting groove 131 abuts against the side of the fixing piece 310, so that the fixing piece 310 is limited and assembled in the limiting groove 131, thus realizing the installation of the communication module 300.

[0043] Clearly, precise positioning is unnecessary during the installation of the communication module 300, achieving "blind operation." During the advancement process, the fixing piece 310 slides along the limiting groove 131 to the bottom of the groove, automatically completing precise positioning. This process requires no tools and eliminates the need to align multiple screw holes, significantly reducing operational difficulty and time consumption, greatly improving production line assembly efficiency, and reducing worker labor intensity. The structure of the limiting groove 131 naturally constrains and guides the movement path of the fixing piece 310, acting like a "track" to ensure that even if the initial placement of the communication module 300 is slightly off, it can automatically correct to the designed position during advancement, avoiding installation misalignment. After the communication module 300 is pushed into place, its two end faces are tightly abutted against the first limiting member 121 and the second limiting member 122, respectively. These two limiting members together eliminate the lateral force of vibration and handling on the communication module 300 along the installation direction (i.e., the first direction). The fixing pieces 310 on the sides of the communication module 300 are enclosed within their respective limiting grooves 131. The bottom of the limiting groove 131 abuts against the end face of the fixing piece 310 to prevent the module from loosening; the inner wall of the limiting groove 131 abuts against the side of the fixing piece 310, effectively limiting the left and right swaying, twisting and vertical displacement of the module in the horizontal plane. The first limiting member 121, the second limiting member 122 and the limiting groove 131 cooperate with each other to limit the communication module 300 from three directions, ensuring the installation stability of the communication module 300.

[0044] The communication module 300 is lifted slightly upward to release the first limiting member 121 from limiting the communication module 300. Then, the communication module 300 is pulled out in the opposite direction of the first direction. At the same time, the fixing piece 310 also moves relative to the limiting groove 131. Finally, it leaves the limiting groove 131 from the assembly opening 132, thus realizing the disassembly of the communication module 300.

[0045] Clearly, the communication module 300 can be disassembled without the need for any special tools or professional skills, which reduces the difficulty of disassembly and increases the speed of disassembly.

[0046] The installation structure 100 of this embodiment can achieve fast and reliable installation of the communication module 300 and facilitate non-destructive disassembly in the future. It can improve product assembly efficiency and after-sales maintenance experience, and solve the defects of low assembly efficiency and high maintenance cost of communication module 300 in cabinet-type air handling equipment in the prior art.

[0047] Optionally, the first direction is perpendicular to the second direction.

[0048] Preferably, the first direction can be the length direction of the communication module 300, and the second direction can be the width direction of the communication module 300.

[0049] like Figure 4 and Figure 7 As shown, in some embodiments of this utility model, the second limiting component 130 includes a support frame and a third limiting plate 134.

[0050] The support frame includes a first support plate 135 and a second support plate 137, both mounted on the mounting base 110. The first support plate 135 and the second support plate 137 are arranged along a second direction, with clearance between them to avoid interference with the fixing piece. A third limiting plate 134 is located on the side of the first support plate 135 and the second support plate 137 away from the mounting base 110. The third limiting plate 134 is connected to the first support plate 135 and the second support plate 137, and together with the side of the first limiting plate away from the mounting base 110, forms a limiting groove 131 with the assembly opening 132.

[0051] In this embodiment, when the fixing piece 310 is installed in the limiting groove 131, the side of the second support plate 137 facing the first support plate 135 abuts against the side of the fixing piece 310 away from the communication module 300. The bottom of the limiting groove 131 abuts against the end of the fixing piece 310 away from the first limiting member 121. In this way, the second limiting components 130 arranged at intervals along the second direction cooperate with each other to limit the communication module 300 in the second direction. In addition, the first support plate 135, the second support plate 137 and the third limiting plate 134 are equivalent to wrapping the fixing piece 310 assembled in the limiting groove 131, which can prevent the communication module 300 from twisting and warping, and further improve the installation stability of the communication module 300.

[0052] Optionally, the shape of the second support plate 137 can be a rectangular plate or a square plate. The second support plate 137 and the first support plate 135 are arranged at intervals along the second direction, and then the first support plate 135 and the second support plate 137 are connected by the third limiting plate 134 located above.

[0053] Optionally, the second support plate 137 is an arc-shaped plate, and one side of the arc-shaped plate can be connected to the first support plate 135 to form a support frame with a U-shaped or C-shaped structure. This support frame structure is more stable than the scheme of arranging the two support plates independently.

[0054] like Figure 9 As shown, furthermore, the end of the third limiting plate 134 facing the first limiting member 121 forms a limiting guide angle 138, which is used to guide the fixing piece 310 to the limiting groove 131. The design of the limiting guide angle 138 plays a guiding role for the fixing piece 310, making it easier for the fixing piece 310 to be inserted into the limiting groove 131.

[0055] like Figure 9 As shown, further, the draft angle of the third limiting plate 134 toward the limiting surface 139 of the mounting base 110 is 3°~10°. A larger draft angle allows for the insertion of the fixing piece 310 into the limiting groove 131 with less force. When the fixing piece 310 is inserted to the bottom of the limiting groove 131, the fixing piece 310 can be squeezed tightly under the combined action of the limiting surface 139 and the first support plate 135, thus achieving a certain degree of fixation of the communication module 300. This ensures that even with a smaller limiting design, the communication module 300 can be fixed in the first direction.

[0056] like Figure 4 , Figure 7 and Figure 9 As shown, the mounting structure 100 further includes a first reinforcing rib 140; the first reinforcing rib 140 is mounted to the mounting base 110; the first reinforcing rib 140 is connected to the second limiting assembly 130. Specifically, the first reinforcing rib 140 is mounted on the side of the arc-shaped second support plate 137 away from the first limiting member 121. By providing the first reinforcing rib 140, the mechanical strength of the second limiting assembly 130 can be improved.

[0057] like Figure 4 and Figure 7 As shown, in some embodiments of the present invention, the mounting structure 100 further includes a guide assembly; the guide assembly includes two guide members 151.

[0058] Both guide members 151 are mounted on the mounting base 110; the two ends of the second limiting member 122 are respectively connected to one end of the two guide members 151, and the other ends of the two guide members 151 extend along the first direction. The guide members 151 are used to abut against the side of the communication module 300.

[0059] In this embodiment, the two guide members 151 and the second limiting member 122 between them together form a wide, open "guide channel" or "entry funnel". When installing the communication module 300, the operator does not need precise alignment. Simply placing the communication module 300 roughly into this channel will allow its sides to naturally contact the guide members 151, achieving "blind operation" and further reducing the difficulty of initial alignment, thus solving the problem of "alignment difficulty". The guide members 151 extend along the first direction, meaning they not only function in the initial stage but also provide lateral guidance throughout the entire insertion stroke of the communication module 300. This ensures that the communication module 300 moves smoothly along a preset straight path, effectively preventing tilting, warping, or jamming due to uneven force during insertion. The installation process becomes smoother and more reliable, with a very high success rate. After installation, the two sides of the communication module 300 abut against the two guide members 151 respectively. This, together with the first limiting member 121, the second limiting member 122, and the limiting groove 131 on the second limiting assembly 130, forms a stable system with all-round constraint, which improves the installation reliability of the communication module 300.

[0060] Optionally, guide 151 can be made of sheet metal.

[0061] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the side of the first limiting member 121 away from the mounting base 110 has a disassembly guide surface 123.

[0062] In this embodiment, the disassembly guide surface 123 facilitates the disassembly and assembly of the communication module 300. At the initial moment of disassembly, the operator needs to overcome the static friction between the communication module 300 and the first limiting member 121. Without the disassembly guide surface 123, this would be a purely direct vertical pull, often requiring considerable force to "break" the initial static state, easily leading to excessive force. The disassembly guide surface 123 forms a force-saving mechanical ramp. When the operator pulls the communication module 300 outward, the end face of the communication module 300 slides along this disassembly guide surface 123. The reaction force of the disassembly guide surface 123 on the communication module 300 can be decomposed into a vertical component and a horizontal component. The vertical component overcomes friction and lifts the communication module 300. The horizontal component helps to "push" the communication module 300 out of the constraint of the first limiting member 121. The pulling force applied by the operator is utilized more effectively, significantly reducing the maximum pulling force required to initiate movement of the communication module 300. Even technicians with less strength can easily start the disassembly process.

[0063] It should be noted that the disassembly guide surface 123 is an inclined surface.

[0064] like Figure 5 As shown, in some embodiments of this utility model, the mounting structure 100 further includes a second reinforcing rib 160. The second reinforcing rib 160 is mounted on the mounting base 110; the second reinforcing rib 160 is mounted on the side of the first limiting member 121 away from the second limiting member 122. This design can enhance the mechanical strength of the first limiting member 121, increase the service life of the first limiting member 121, and reduce the risk of the first limiting member 121 breaking due to repeated disassembly.

[0065] like Figure 4 As shown, in some embodiments of the present invention, the mounting structure 100 further includes a support component 170; the support component 170 is disposed between the first limiting member 121 and the second limiting member 122, and is used to support the communication module 300.

[0066] In this embodiment, the support component 170 is provided to support the communication module 300, enhancing its overall resistance to bending and deformation. This ensures the structural integrity and reliability of the communication module 300 under various operating conditions and extends its service life. Existing communication modules typically connect to the device motherboard via board-to-board connectors or cable sockets. If the module lacks support in the middle, even slight bending or displacement can lead to poor connector contact, intermittent connections, or even misaligned pins, causing communication failures. The support component 170 provides a stable reference plane for the module, ensuring that the module remains flat throughout the entire installation area. This allows the connectors on the back of the module to be precisely and parallelly aligned and plugged into the corresponding interfaces on the motherboard, avoiding stress caused by module deformation and significantly improving the reliability and consistency of the electrical connection.

[0067] Furthermore, the support assembly 170 effectively suppresses vibration of the communication module 300, increasing the rigidity of the entire structure. The top surface of the support assembly 170 (i.e., the side away from the mounting base) can form a complete support plane together with the first limiting member 121 and the second limiting member 122. When the module is pushed in, it can slide flat against this complete plane, rather than being "rested" on two isolated points. This makes the installation process smoother and more stable, provides better handling, and further improves the assembly experience and efficiency. The support assembly 170 distributes most of the vertical load, reducing the load on the first limiting member 121 and the second limiting member 122, allowing them to focus more on the horizontal limiting and locking functions, thereby improving the long-term durability of the entire mounting structure.

[0068] Optionally, the support assembly 170 includes a first support member 171 and a second support member 172; the first support member 171 and the second support member 172 are arranged at a distance along a first direction. One end of the second support member 172 is connected to the second limiting member 122, and the other end extends in the opposite direction of the first direction. One end of the first support member 171 is connected to the first limiting member 121, and the other end extends along the first direction. The height of the first support member 171 is lower than the height of the first limiting member 121 to form a height difference.

[0069] In this embodiment, the height of the first support member 171 is lower than the height of the first limiting member 121, effectively forming a ramp from low to high. The operator can naturally tilt the communication module 300 at a small angle, allowing the bottom of the module to easily pass over the lower first support member 171. Then, using this support member as a fulcrum, the operator gently presses down on the tail of the module (the end closest to the first limiting member 121), causing the module to rotate around it like a "rocker arm," ultimately fitting horizontally onto the second support member 172 and the second limiting member 122. This process avoids collisions and interference during the initial installation phase, ensuring smooth installation of the communication module 300. The "tilt-then-flat" installation action aligns more with natural human operating habits. Operators typically hold one end of the communication module 300 with one hand, and tilting it in is the most intuitive and effortless method. This design conforms to, rather than contradicts, this natural habit, transforming a potential operational disadvantage (tilt) into an advantage for installation guidance, greatly improving the operating experience and assembly speed.

[0070] Optionally, the first support member 171 and the second support member 172 have the same height.

[0071] like Figure 4 As shown, optionally, the side of the second support member 172 away from the second limiting member 122 is a guide inclined surface 173. This guide inclined surface 173 has a lower end and a higher end, guiding the communication module 300 during installation and ensuring that the communication module 300 can slide along the guide inclined surface 173 towards the upper end of the second support member 172. The low height of the first support member 171 solves the interference problem at the starting end of the communication module 300. The guide inclined surface 173 of the second support member 172 solves the interference problem at the end. From start to finish, the entire installation process is handled by a series of guiding features. The operator does not need to be careful or precisely manipulate the equipment; a roughly correct "tilt-down" action is sufficient, and the communication module 300 will automatically and smoothly reach the predetermined position under the action of various guiding structures. This greatly reduces the skill requirements for the operator and makes the assembly process very natural and intuitive.

[0072] like Figure 10As shown, a second aspect of this utility model provides a cabinet-type air handling unit.
