Description

Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning (HVAC) equipment technology, and more particularly to a housing assembly and HVAC equipment. Background Technology

[0002] In the field of HVAC equipment, the housing components of ceiling-mounted equipment typically require a reliable connection to the building's ceiling structure. Currently, the connection between the housing components and the ceiling flange is mostly achieved using bolts or snap-fit ​​structures. However, existing housing components suffer from problems such as unstable connections and difficulty in disassembly. Utility Model Content

[0003] This application provides a housing assembly and HVAC equipment to solve the problems of existing housing assemblies having loose connections and being difficult to disassemble.

[0004] In a first aspect, this application provides a housing assembly, including: a main body and a connecting structure;

[0005] The connection structure includes a sliding member and an abutment member that are connected together;

[0006] The sliding member is detachably connected to the main body, and the surface of the sliding member away from the main body can be used to abut against the first surface of the ceiling flange.

[0007] The abutment is disposed on the side of the slider away from the main body, and the surface of the abutment facing the slider can be used to abut against the second surface of the ceiling flange.

[0008] By adopting the above technical solution, the shell assembly includes a main body and a connecting structure. The connecting structure includes a sliding member and a stop member connected to each other. The sliding member is detachably connected to the main body, which facilitates installation and adjustment. The stop member works in cooperation with the sliding member to form a two-way clamping effect on the ceiling flange.

[0009] In the specific implementation process, the sliding parts and the main body are detachably connected, which can achieve quick installation and disassembly; at the same time, the cooperation between the sliding parts and the abutment parts can form a two-way clamping structure, so that the ceiling flange is firmly fixed between the two, avoiding loosening or displacement.

[0010] Understandably, compared to existing technologies that use a single fixing or simple snap-fit ​​solution, the housing assembly of this application achieves a more reliable connection effect through the synergistic effect of sliding parts and abutment parts, while also taking into account the ease of disassembly and assembly. It is suitable for ceiling flanges of different specifications, improving installation adaptability and structural stability.

[0011] In some embodiments of this application, the sliding member is provided with a protrusion that protrudes toward the abutment and can be used to abut against the first surface of the ceiling flange.

[0012] By incorporating protrusions, the contact with the ceiling flange is optimized, reducing the contact area to increase the clamping force per unit area. The specific orientation of the protrusions guides the ceiling flange into the predetermined installation position, achieving reliable line or point contact. This structural design effectively reduces installation resistance while enhancing connection stability and preventing loosening during use. The cooperation between the protrusions and the abutment creates a mechanical balance, ensuring that the clamping force is evenly distributed across the ceiling flange.

[0013] In some embodiments of this application, the abutting member includes a bent portion that protrudes toward the sliding member and can be used to abut against the second surface of the ceiling flange.

[0014] The protruding bend ensures a reliable fit with the second surface of the ceiling flange. This protruding bend compensates for thickness tolerances in the ceiling flange, maintaining a stable clamping position during assembly and use. The bend and the protruding sliding component work together to form a two-way constraint system, effectively preventing loosening of the connection.

[0015] In some embodiments of this application, the abutting member includes a connecting portion and a guiding portion; a first end of the connecting portion is connected to the sliding member, and a second end of the connecting portion is connected to the bending portion;

[0016] The first end of the guide portion is connected to the bending portion, and the second end of the guide portion gradually moves away from the slider.

[0017] The connecting section transmits the clamping force of the sliding component to the bending section, ensuring the mechanical integrity of the bidirectional clamping. The guide section reduces the insertion resistance of the ceiling flange, enabling automatic centering during installation. The continuous transition between the connecting section and the guide section optimizes stress distribution, avoids stress concentration in the bending area, and improves structural durability.

[0018] In some embodiments of this application, the connecting portion is configured as an elastic connecting portion, which can apply a force toward the sliding member to the bending portion.

[0019] The flexible connection provides continuous elastic restoring force, ensuring that the bending section maintains a constant clamping pressure on the ceiling flange. This elastic restoring force compensates for thickness tolerances in the ceiling flange, adapting to installation requirements under various working conditions. The synergistic effect of the flexible connection and the bending section forms a self-adjusting clamping system, simplifying assembly while ensuring connection stability, avoiding stress concentration issues common in rigid connections, and suppressing vibration-induced loosening during use.

[0020] In some embodiments of this application, the sliding member is provided with a protrusion that protrudes toward the abutting member and can be used to abut against the first surface of the ceiling flange.

[0021] The bent portion and the protrusion are spaced apart, and the first end of the bent portion is away from the connecting portion relative to the protrusion.

[0022] The spaced arrangement of protrusions and bends creates a clamping space, allowing the ceiling flange to smoothly enter the predetermined position during installation. The protrusions provide the main support points, working in conjunction with the elastic clamping force of the bends to form a stable two-way constraint.

[0023] In some embodiments of this application, the slider and the abutment are integrally formed.

[0024] By integrating the sliding and abutment components, the overall structural rigidity and connection precision can be improved, the manufacturing process can be simplified, and the number of parts can be reduced. One-piece molding ensures the continuity of force transmission and avoids stress concentration problems caused by connecting multiple parts.

[0025] In some embodiments of this application, the main body is provided with a sliding groove, the sliding member is provided with a sliding part, and the sliding part is slidably disposed in the sliding groove.

[0026] By using sliding grooves and sliding parts, the sliding parts can be positioned and moved relative to the main body, making installation easier.

[0027] In some embodiments of this application, there are multiple sliding grooves and multiple sliding members, and the number of sliding members corresponds to the number of sliding grooves;

[0028] The main body is provided with a limiting part, which is spaced apart from the bottom surface of the sliding groove, and the limiting part can be used to abut against the sliding member.

[0029] A distributed guiding structure can be formed by multiple sliding grooves and multiple sliding parts. The synergistic effect of the limiting part and the sliding groove can control the movement stroke of the sliding part, ensuring both the degree of freedom of adjustment and preventing overtravel and detachment.

[0030] In a second aspect, this application provides a heating, ventilation, and air conditioning (HVAC) device, including a housing assembly as described in any of the first aspects. Attached Figure Description

Detailed Implementation

[0041] In the field of HVAC equipment installation, the housing components of ceiling-mounted equipment typically require a reliable connection to the building's ceiling structure. Currently, the connection between the housing and the ceiling flange often employs bolt fixing or snap-fit ​​structures.

[0042] This type of connection often requires precise alignment during installation and is inconvenient to disassemble and maintain. When there are dimensional deviations or installation errors in the ceiling flange, it can easily lead to loose connections or poor sealing. Furthermore, existing connection structures may loosen after long-term use, affecting the stability and performance of the equipment.

[0043] Therefore, there is an urgent need for a shell connection solution that is easy to install, reliable in connection, and highly adaptable.

[0044] To address the aforementioned technical problems, this application provides a housing assembly, including a main body and a connecting structure. The connecting structure includes a sliding member and an abutting member connected to each other. The sliding member is detachably connected to the main body, facilitating installation and adjustment. The abutting member cooperates with the sliding member to form a bidirectional clamping effect on the ceiling flange.

[0045] In the specific implementation process, the sliding parts and the main body are detachably connected, which can achieve quick installation and disassembly; at the same time, the cooperation between the sliding parts and the abutment parts can form a two-way clamping structure, so that the ceiling flange is firmly fixed between the two, avoiding loosening or displacement.

[0046] Understandably, compared to existing technologies that use a single fixing or simple snap-fit ​​solution, the housing assembly of this application achieves a more reliable connection effect through the synergistic effect of sliding parts and abutment parts, while also taking into account the ease of disassembly and assembly. It is suitable for ceiling flanges of different specifications, improving installation adaptability and structural stability.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] See Figures 1 to 4 This application provides a housing assembly, which may include a main body 100 and a connecting structure 200.

[0055] The main body 100 can serve as the load-bearing structure of the shell assembly, providing an installation reference and structural support for the connecting structure 200. The main body 100 can be configured as a frame type, box type, or other structural form as needed, and its internal space can be used to accommodate relevant functional components of the HVAC equipment.

[0056] The connection structure 200 can serve as a component for connecting the housing assembly to an external mounting base (such as the ceiling flange 10), providing an adjustable and reliable connection method.

[0057] The connection structure 200 may include a sliding member 210 and an abutment member 220 connected to each other. The sliding member 210 and the abutment member 220 can work together to achieve an adjustable connection between the housing assembly and the ceiling flange 10.

[0058] The sliding element 210 provides a guide and support platform for the ceiling flange 10. The sliding characteristic of the sliding element 210 is reflected in its interaction with the ceiling flange 10; the ceiling flange 10 can slide relative to the surface of the sliding element 210 to achieve positioning and engagement. The sliding element 210 provides guidance during installation, ensuring that the ceiling flange 10 can be accurately connected to the housing assembly.

[0059] The sliding component 210 can be detachably connected to the main body 100. The detachable connection can be implemented in various ways, including but not limited to screw connections, snap-fit ​​connections, or plug-in connections, ensuring structural stability after assembly while allowing for disassembly when needed. By fixing the sliding component 210 to the main body 100 through this detachable connection, a stable installation reference surface can be formed, providing an accurate positioning reference for the subsequent installation of the ceiling flange 10.

[0060] The surface of the sliding member 210 away from the main body 100 can be used to abut against the first surface of the ceiling flange 10. The surface of the sliding member 210 away from the main body 100 can provide load-bearing and positioning functions. The shape and size of the surface of the sliding member 210 away from the main body 100 are designed according to the structural characteristics of the ceiling flange 10, and can be a flat surface, a curved surface, or an irregularly shaped surface with positioning features. In the actual assembly process, the first surface of the ceiling flange 10 can slide along this contact surface until it reaches the predetermined position, achieving initial positioning.

[0061] The abutment 220 can be positioned on the side of the slider 210 away from the main body 100. The abutment 220, together with the slider 210, forms a clamping space for the ceiling flange 10. An appropriate distance can be maintained between the abutment 220 and the slider 210; this distance can be set considering the standard thickness and allowable tolerances of the ceiling flange 10, and is not specifically limited here. This arrangement of the abutment 220 ensures that when the ceiling flange 10 is installed in place, it can be reliably constrained within the clamping space formed by the slider 210 and the abutment 220.

[0062] The surface of the abutment 220 facing the slider 210 can be used to abut against the second surface of the ceiling flange 10. The surface of the abutment 220 facing the slider 210 can provide a reverse supporting force, and together with the contact surface of the slider 210, complete the bidirectional fixation of the ceiling flange 10. The surface of the abutment 220 facing the slider 210 can match the shape of the second surface of the ceiling flange 10, including different forms such as a flat surface, a beveled surface, or a surface with anti-slip texture.

[0063] The first surface of the ceiling flange 10 can refer to the surface close to the housing assembly, and the first surface of the ceiling flange 10 can be used to bear the supporting force from the sliding member 210. The second surface of the ceiling flange 10 can refer to the surface away from the housing assembly, and the second surface of the ceiling flange 10 can be used to bear the elastic clamping force applied by the abutment member 220. The first surface and the second surface of the ceiling flange 10 can together constitute the stress-bearing area of ​​the ceiling flange 10.

[0064] The combined design of the sliding member 210 and the abutment member 220 achieves guiding positioning during installation and stable retention of the final connection. The sliding member 210 provides a sliding track and a first contact surface for the ceiling flange 10, while the abutment member 220 provides a reverse restraint force. The relative positional relationship between the two determines the size of the clamping space, which can accommodate ceiling flanges 10 of different thicknesses. In specific implementations, the sliding member 210 can be designed with a structure with a guide ramp to facilitate the introduction of the ceiling flange 10; the abutment member 220 can be equipped with an elastic element to compensate for dimensional tolerances and maintain a constant clamping force.

[0065] Through the coordinated operation of the sliding member 210 and the abutment member 220, bidirectional clamping and fixing of the ceiling flange 10 is achieved. The detachable connection design between the sliding member 210 and the main body 100 ensures positional adjustability during installation and provides the main load-bearing capacity for the ceiling flange 10 through its contact surface. The reverse constraint surface formed by the abutment member 220 at the distal end of the sliding member 210, together with the sliding member 210, constitutes a stable clamping space, ensuring connection reliability. This structural design can adapt to ceiling flanges 10 of different thicknesses, simplifying the installation process while providing a durable and stable connection effect.

[0066] As a specific embodiment of this application, the sliding member 210 may be provided with a protrusion 211, which protrudes toward the abutment member 220 and can be used to abut against the first surface of the ceiling flange 10.

[0067] The protrusion 211 optimizes the contact with the ceiling flange 10 and enhances positioning reliability. The protrusion 211 extends towards the abutment 220, ensuring stable line or point contact with the first surface of the ceiling flange 10. The cross-sectional shape of the protrusion 211 can be arc-shaped, trapezoidal, or other geometry suitable for stress distribution, and its top can be designed as a flat or curved surface to accommodate different contact requirements.

[0068] By setting the protrusion 211, the actual contact area can be reduced, the frictional resistance during installation can be reduced, and the pressure per unit area can be increased by concentrating the force, thereby enhancing the connection stability. The structural features of the protrusion can also serve as an installation positioning reference to guide the ceiling flange 10 to be accurately positioned.

[0069] As a specific embodiment of this application, the abutment portion may include a bent portion 221, which may protrude toward the sliding member 210 and be used to abut against the second surface of the ceiling flange 10. The bent portion 221 may serve as a key load-bearing structure to form a structure that contacts the ceiling flange 10.

[0070] The bent portion 221, through its bending structure protruding towards the sliding member 210, can create a contact interface with pre-tension force. Its bending angle and radius of curvature can be determined according to the required elastic deformation of the ceiling flange 10. The protrusion height of the bent portion 221 can maintain a cooperative relationship with the protrusion 211 on the sliding member 210, and the two together define a variable clamping space to accommodate ceiling flanges 10 of different thicknesses.

[0071] As a specific embodiment of this application, the abutment 220 may include a connecting portion 222 and a guide portion 223.

[0072] The first end of the connecting part 222 can be connected to the sliding member 210, and the second end of the connecting part 222 can be connected to the bending part 221. The connecting part 222 can serve as a main load-bearing component. The first end of the connecting part 222 can be rigidly connected to the sliding member 210 through a mechanical connection to ensure an effective transmission path of the clamping force. The second end of the connecting part 222 can be connected to the bending part 221 in a smooth transition manner. For example, it can be set as an arc transition area. The cross-sectional shape of the connecting part 222 can be set as a gradient, and the width and thickness can gradually change from the first end to the second end to adapt to the stress requirements of different sections.

[0073] The first end of the guide portion 223 can be connected to the bending portion 221, and the second end of the guide portion 223 can gradually move away from the slider 210. The guide portion 223 can be used to provide spatial guidance. The first end of the guide portion 223 maintains a continuous curved surface connection with the bending portion 221, forming a streamlined transition without abrupt changes. The second end of the guide portion 223 can gradually move away from the slider 210 with an expansion angle of 15 degrees to 45 degrees, forming a trumpet-shaped guide channel. The longitudinal section of the guide portion 223 can be curved or zigzag, and the edges of the guide portion 223 can be rounded to prevent scratching the surface of the ceiling flange 10 during installation.

[0074] The abutment member 220 achieves multiple functional integrations through the coordinated operation of the bending portion 221, the connecting portion 222, and the guide portion 223. The bending portion 221 provides elastic clamping force to ensure tight contact with the ceiling flange 10; the connecting portion 222 establishes a stable force transmission path, reliably transmitting the clamping force to the sliding member 210; and the guide portion 223 forms a gradually expanding guide channel, reducing installation resistance. The combined design of the bending portion 221, the connecting portion 222, and the guide portion 223 achieves reliable clamping, force transmission, and installation guidance within a limited space, ensuring connection strength while improving assembly convenience.

[0075] As a specific embodiment of this application, the connecting part 222 can be configured as an elastic connecting part 222, which can apply a force toward the sliding member 210 to the bending part 221.

[0076] The elastic connection 222 can generate a continuous restoring force through elastic deformation, ensuring a stable contact pressure between the bent portion 221 and the ceiling flange 10. The elastic connection 222 can also automatically adapt to changes in the thickness of the ceiling flange 10, maintaining a constant clamping force during assembly and use. The structure of the elastic connection 222 can be implemented in ways including, but not limited to, bending an elastic metal sheet to achieve deformation recovery through the material's inherent elasticity; or as an injection-molded structure with an elastic arm, utilizing the flexibility of the plastic material to generate the required elasticity; or by combining a metal spring with a rigid support.

[0077] The elastic connecting portion 222 applies a force toward the sliding member 210 to the bending portion 221, forming a self-adjusting clamping mechanism. When the ceiling flange 10 is inserted between the sliding member 210 and the abutment member 220, the bending portion 221 is compressed and displaced, causing the elastic connecting portion 222 to undergo elastic deformation. The restoring force generated by the deformation is transmitted to the ceiling flange 10 through the bending portion 221, forming a stable clamping state. The magnitude of this force can be controlled by adjusting the material thickness, bending radius, or structural form of the elastic connecting portion 222 to adapt to different load-bearing requirements.

[0078] As a specific embodiment of this application, the bent portion 221 may be spaced apart from the protrusion 211, and the first end of the bent portion 221 is away from the connecting portion 222 relative to the protrusion 211.

[0079] The spacing between the bent portion 221 and the protrusion 211 creates a clamping space that accommodates the ceiling flange 10 and provides it with a constrained environment. The geometry of the accommodating space is determined by the relative positional relationship between the bent portion 221 and the protrusion 211. Its width dimension can be slightly larger than the standard thickness of the ceiling flange 10 to allow for fine-tuning during assembly while ensuring a tight clamped state. The longitudinal extension of the clamping space can be matched to the contact area of ​​the ceiling flange 10 to ensure sufficient contact area to distribute clamping stress.

[0080] As a specific embodiment of this application, the slider 210 and the abutment 220 can be integrally formed. Integral sliding member 210 and abutment 220 simplifies the manufacturing process and improves the overall integrity of the connection structure 200. The slider 210 and abutment 220 can be manufactured as a single part from the same material using a molding process, eliminating the assembly steps required for traditional split structures.

[0081] The integrated sliding member 210 and abutting member 220 can be manufactured through processes such as metal stamping, injection molding or die casting. In the case of metal materials, a single metal plate can be formed by continuous bending; in the case of plastic materials, the complete structure can be injection molded in one go.

[0082] The integrated sliding member 210 and abutment member 220 optimize the force transmission path. The connection area between the sliding member 210 and abutment member 220 lacks a mechanical connection interface, avoiding stress concentration problems that may occur with traditional bolts or riveting. The elastic characteristics of the connection portion 222 can be achieved through gradual changes in material thickness or structural shape, such as designing variable thickness areas or pre-setting a bending radius.

[0083] By integrating the slider 210 and the abutment 220, the number of parts can be reduced, manufacturing costs and assembly time can be lowered, product maintenance can be simplified, and loosening problems that may occur when connecting multiple parts can be avoided. It can also eliminate the fit tolerance of the connection part 222, improve dimensional accuracy and consistency, and further optimize load transfer efficiency, thereby enhancing overall strength and durability.

[0084] As a specific embodiment of this application, the main body 100 may be provided with a sliding groove 110, and the slider 210 may be provided with a sliding part 212, which can be slidably disposed in the sliding groove 110.

[0085] The sliding groove 110 can serve as a guide structure, providing a movement trajectory and support base for the slider 210. The cross-sectional shape of the sliding groove 110 can be customized based on the structural characteristics of the sliding part 212, and can be T-shaped, dovetail-shaped, or rectangular, etc., to allow for sliding freedom while restricting displacement in other directions. The length of the sliding groove 110 is determined according to the adjustment range of the slider 210, and limiting structures can be provided at both ends to prevent slippage.

[0086] The sliding member 210 can be a structure that cooperates with the main body 100. Its shape can form a dynamic fit relationship with the sliding groove 110. For example, the sliding part 212 can adopt an integral slider structure, or it can be designed as a multi-roller or ball bearing structure to reduce frictional resistance.

[0087] As a specific embodiment of this application, the number of sliding grooves 110 can be multiple, the number of sliding members 210 can be multiple, and the number of sliding members 210 and the number of sliding grooves 110 can be set accordingly.

[0088] Multiple sliding grooves 110 can be arranged parallel to each other along the height direction on the main body 100, forming a hierarchical guide structure. Each sliding groove 110 can be equidistant in the vertical direction, and the spacing between each sliding groove 110 can be determined according to the height of the ceiling flange 10. This multi-level arrangement of sliding grooves 110 allows the sliding element 210 to form independent support points at different height positions, constructing a stable three-dimensional constraint system.

[0089] The extension direction of the sliding groove 110 can be consistent with the installation direction of the ceiling flange 10, and the length dimension covers the required adjustment range.

[0090] Multiple sliders 210 can be arranged in a one-to-one correspondence with multiple sliding grooves 110, and the sliders 210 are embedded in the paired sliding grooves 110 to form a sliding pair. The sliders 210 are arranged in parallel in the vertical direction and their length direction is consistent with the sliding grooves 110, forming a multi-layered linear guide structure.

[0091] The main body 100 may be provided with a limiting part 120. The limiting part 120 may be provided at a distance from the bottom surface of the sliding groove 110, and the limiting part 120 may be used to abut against the sliding member 210. The limiting part 120 may serve as a stroke control structure to limit the range of movement of the sliding member 210 within the sliding groove 110.

[0092] The limiting member and the bottom surface of the sliding groove 110 are arranged parallel to each other, and a guide space for accommodating the sliding member 210 can be formed between them. The limiting part 120 can extend along the length direction of the sliding groove 110, and the vertical distance between the limiting part 120 and the bottom surface of the groove can be slightly greater than the thickness of the sliding member 210, so as to ensure that the sliding member 210 can slide freely within the limited space without detaching.

[0093] The main body 100 is provided with a limiting part 120 to ensure that the sliding member 210 moves within a predetermined range through mechanical constraints, preventing damage from overtravel. The limiting part 120 and the sliding groove 110 together form a stable guide channel, enabling the sliding member 210 to slide smoothly.

[0094] In summary, as Figure 3 As shown, when the ceiling flange 10 is inserted into the housing assembly, the ceiling flange 10 first contacts the involute slope of the guide part 223. The guiding effect of the guide part 223 causes the flange to automatically correct the position deviation. At this time, the ceiling flange 10 is mainly subjected to the guiding friction force and the initial pre-tightening force of the elastic connection part 222.

[0095] Next, as Figure 4 As shown, the ceiling flange 10 simultaneously contacts the protrusion 211 of the sliding member 210 and the bent portion 221 of the abutment member 220. The protrusion 211 forms the main support point, and the bent portion 221 generates an increasing clamping force through elastic deformation. The ceiling flange 10 bears the normal support force from the protrusion 211 and the elastic pressure from the bent portion 221.

[0096] Finally, the ceiling flange 10 is fully inserted into the clamping space formed by the protrusion 211 and the bending part 221. The elastic connection part 222 reaches the preset deformation amount, and the bending part 221 applies a stable clamping force. At this time, the ceiling flange 10 is subjected to a balanced normal constraint force. The synergistic effect of the protrusion 211 and the bending part 221 forms a force couple balance, effectively resisting the torsional tendency of the flange.
