Description

Technical Field

[0001] This utility model belongs to the field of air conditioner technology, specifically relating to an air guide plate structure and an air conditioner using the same. Background Technology

[0002] In modern home environments, air conditioning systems are an indispensable part, and their air deflector assemblies, as key components for regulating airflow direction, directly affect the user experience. Current technologies typically employ a crank and connecting rod structure to drive the air deflector. While this structure is compact and easy to operate, it suffers from the following problems: each air deflector needs to be individually connected to the crank, which in turn connects to the connecting rod, resulting in cumbersome assembly steps and low production efficiency; the overlap between the air deflector and the crank is difficult to control—insufficient overlap leads to loosening and failure, while excessive overlap results in interference fit difficulties and can easily cause air deflector deformation. Therefore, there is an urgent need for a simple and easy-to-assemble air conditioning air deflector assembly to solve the problems of low assembly efficiency and easy deformation in existing technologies.

[0011] In some embodiments, the transmission assembly includes a motor crankshaft and a guide rod, the motor crankshaft being connected to the output end of the drive assembly, and the guide rod being hinged to the drive connection portion of both the motor crankshaft and all the guide vanes.

[0038] Example 1

[0039] This embodiment provides an air guide plate structure, such as Figures 1-10 As shown, the air guide plate structure includes a drive assembly 1, a transmission assembly 2, a support assembly 3, and an air guide assembly 4. The output end of the drive assembly 1 is connected to the air guide assembly 4 through the transmission assembly 2. The air guide assembly 4 is located at the opening of the support assembly 3. The air guide assembly 4 includes at least one air guide plate 41. One side of the air guide plate 41 has a rotating connection part 42, and the other side of the air guide plate 41 has a drive connection part 43 integrally formed with the air guide plate 41. The air guide plate 41 is disposed at the opening of the support assembly 3 through the rotating connection part 42, and the transmission assembly 2 is connected to the air guide plate 41 through the drive connection part 43.

[0040] The drive assembly 1 is fixed to the support assembly 3, and its output end is directly connected to the transmission assembly 2. The other end of the transmission assembly 2 is simultaneously connected to the drive connection part 43 of all the air guide plates 41. The air guide assembly 4 is located at the opening of the support assembly 3, and the air guide plates 41 are mounted on both sides of the opening of the support assembly 3 through the rotating connection part 42, so that the air guide plates 41 can rotate around the rotating connection part 42. The drive connection part 43 is located on the side of the air guide plate 41 away from the rotating connection part 42, is integrally formed with the air guide plate 41 and exposed outside the air guide plate 41 body, and the transmission assembly 2 is connected to the drive connection part 43 through a hinge. The opening frame of the support assembly 3 wraps around the edge of the air guide plate 41, and the axis of the rotating connection part 42 is parallel to the opening direction of the support assembly 3.

[0041] Drive assembly 1 provides rotational power output, and transmission assembly 2 converts the rotational motion of drive assembly 1 into a synchronized action that controls the oscillation of multiple air guide vanes 41. Support assembly 3 provides structural support and defines the motion trajectory of the air guide vanes 41. Air guide assembly 4 adjusts the airflow direction by the physical deflection of the air guide vanes 41. Rotary connection 42 serves as the rotation fulcrum of the air guide vanes 41, constraining them to rotate only around a single axis. Drive connection 43 serves as a power input interface, directly transmitting the driving force of transmission assembly 2 to the air guide vane 41 body.

[0042] When drive assembly 1 is activated, its output shaft drives transmission assembly 2. Transmission assembly 2 simultaneously pulls the drive connection parts 43 of all air guide plates 41, forcing the air guide plates 41 to rotate around the rotating connection part 42 as an axis. The integrated design of the drive connection part 43 and the air guide plate 41 allows the driving force to act directly on the air guide plate 41 body, avoiding the intermediate transmission link of traditional crank-connecting rods. When the air guide plate 41 rotates, the rotating connection part 42 slides stably within the support assembly 3, ensuring motion accuracy.

[0043] In this embodiment, the drive connection part 43 and the air guide plate 41 are integrally formed, which completely eliminates the assembly process of the traditional air guide plate and crank, and solves the problem of low assembly efficiency; after eliminating the separate crank structure, the problem of overlap control is completely avoided, and the risk of air guide plate deformation caused by interference assembly is avoided.

[0044] In a specific embodiment, the support assembly 3 includes a detachably connected support frame 31 and a cover plate 32. The rotating connection part 42 cooperates with the support frame 31, and the driving connection part 43 is confined within the accommodating space formed by the cover plate 32 and the support frame 31. The cover plate 32 is provided with a clearance hole for the driving connection part 43 to pass through.

[0045] The support frame 31, as the main structure, is fixed to the edge of the air conditioner outlet. Mounting positions are provided on both sides of its opening. A cover plate 32 detachably covers the mounting area of ​​the drive connection part of the support frame 31. When closed, the two form a physically enclosed space. A through hole is opened in the center of the cover plate 32, and it is coaxially aligned with the corresponding area of ​​the support frame 31. The support frame 31 provides a pivot point for the rotation of the air guide plate 41, ensuring stable rotation of the rotating connection part 42, and also provides an initial positioning base for the drive connection part 43. The cover plate 32, through its covering action, forms a closed receiving space, restricting the axial displacement of the drive connection part 43. The through hole provides a rotation channel for the drive connection part 43 and isolates unnecessary contact.

[0046] The process of fitting the cover plate 32 with the support frame 31 is divided into three stages: during assembly, the drive connection part 43 is placed horizontally in the installation area of ​​the support frame 31, and the cover plate 32 covers the area and is fixed by the connector to form a receiving space; during operation, the drive connection part 43 can rotate freely in the receiving space, and the through hole of the cover plate 32 ensures that its connection end with the transmission component 2 is exposed; during disassembly, the drive connection part 43 can be directly taken out by removing the cover plate 32.

[0047] The split design of the support component 3 provided in this embodiment allows the drive connection part 43 to be assembled by horizontal placement, without the need to squeeze the air guide plate 41, thus ensuring structural integrity.

[0048] In a specific embodiment, the rotating connection part 42 is a pin, which cooperates with the bushing 311; wherein, the bushing 311 is disposed on the support frame 31 or disposed on the air guide plate 41 and is integrally formed with the air guide plate 41.

[0049] When the bushing 311 is mounted on the support frame 31, the pin of the air guide plate 41 can be directly inserted into the bushing 311 of the support frame 31. During assembly, the air guide plate 41 does not need to precisely position the bushing, which greatly reduces the assembly difficulty. At the same time, the support frame 31 serves as a fixed base to bear the wear of the bushing 311, and the air guide plate 41 itself has no frictional wear. During maintenance, only the bushing 311 on the support frame 31 needs to be replaced, which reduces maintenance costs.

[0050] When the bushing 311 and the air guide plate 41 are integrally formed, the fitting gap between the pin and the bushing 311 is directly formed during the injection molding process, eliminating the assembly process of the independent bushing; the integral structure avoids the risk of separation between the pin and the bushing 311 due to vibration, and the overall rigidity of the air guide plate 41 is strengthened while reducing the number of parts and material costs.

[0051] In a specific embodiment, the drive connection part 43 is a crankshaft structure, and the support frame 31 is provided with a mating opening 312 for the crankshaft structure to pass through. The crankshaft structure refers to the drive connection part 43 being designed as a cylinder with an eccentric shaft section, whose axis is parallel to the axis of the rotating connection part 42 but has a radial offset distance. The end of the eccentric shaft section is provided with a hinge interface for connecting the transmission assembly 2, and the whole is integrally injection molded with the air guide plate 41 body to form a non-removable structure. The cylindrical part of the crankshaft structure is horizontally embedded in the mating opening 312 of the support frame 31. The diameter of the cylinder is slightly smaller than the diameter of the mating opening 312 to form a rotational clearance, allowing the crankshaft structure to rotate freely within the mating opening 312. The axial height of the mating opening 312 is greater than the diameter of the crankshaft structure, allowing the crankshaft structure to tilt axially during rotation. The eccentric shaft section of the crankshaft structure is exposed after passing through the mating opening 312, and its hinged interface is connected to the transmission assembly 2. The inner wall of the mating opening 312 and the cylindrical surface of the crankshaft structure form a sliding friction pair, converting the tension of the transmission assembly 2 into the rotational torque of the air guide plate 41 around the rotating connection part 42.

[0052] In a specific embodiment, the cover plate 32 is connected to the support frame 31 by at least one fastener, and the cover plate 32 is provided with a square pin 321 in the middle for insertion into the positioning hole of the support frame 31.

[0053] The fasteners may be common mechanical fasteners such as screws, bolts, or clips. When connecting the cover plate 32 and the support frame 31 using fasteners, mounting holes or slot structures are usually provided at corresponding positions on the support frame 31 and the cover plate 32. After the fastener passes through the through hole of the cover plate 32 or is embedded in its clip structure, it forms a mechanical lock with the threaded hole or snap-fit ​​position of the support frame 31. For example, when a screw is used as the fastener, the mounting area of ​​the support frame 31 has a columnar structure with internal threads, and a through hole is opened at the corresponding position on the cover plate 32. The screw passes through the through hole and is screwed into the threaded column to generate axial pressure, pressing the cover plate 32 and the support frame 31 tightly and fixed. If a clip structure is used, the fastener may be an elastic clip protrusion. By pressing the cover plate 32, the clip protrusion is embedded into the groove of the support frame 31 to achieve self-locking. Regardless of the specific form, the core function of the fastener is to provide a detachable mechanical connection, ensuring that a stable receiving space is formed after the cover plate 32 and the support frame 31 are closed.

[0054] The square pin 321 functions by engaging with the positioning hole of the support frame 31 to achieve rapid pre-positioning of the cover plate 32 and the support frame 31. The non-circular cross-section of the square pin 321, when inserted into the corresponding positioning hole of the support frame 31, restricts the horizontal rotational freedom of the cover plate 32, preventing circumferential displacement of the cover plate 32 relative to the support frame 31. During assembly, the operator first inserts the square pin 321 into the positioning hole of the support frame 31, utilizing its shape-fitting characteristics to automatically correct the installation angle and position of the cover plate 32, and then finally secures it using fasteners. This design not only simplifies the assembly alignment process but also improves the connection accuracy between the cover plate 32 and the support frame 31, avoiding interference in the movement of the drive connection part 43 due to misalignment. Compared to cylindrical pins, the square structure has higher torsional resistance, ensuring positioning stability.

[0055] In a specific embodiment, the height h of the mating opening 312 and its radius r satisfy the following relationship: h = 1.5r, and the radius R of the clearance hole and the radius r of the mating opening 312 of the support frame 31 satisfy the following relationship: R = r + 0.1mm.

[0056] The height h of the fitting opening 312 is set to 1.5 times the radius r. This ensures the freedom of movement of the crankshaft structure through axial space allowance. When the crankshaft structure of the drive connection part 43 rotates within the fitting opening 312, the design of h = 1.5r makes the axial height of the opening slightly larger than the diameter of the crankshaft structure cylinder. This allowance allows the crankshaft structure to tilt slightly when a non-pure radial force is applied by the transmission assembly 2, avoiding frictional resistance or movement jamming caused by excessive axial constraint.

[0057] The radius R of the clearance hole is set to be 0.1 mm larger than the radius r of the mating opening 312 of the support frame 31. This achieves precise control over assembly tolerance and movement clearance. Since the crankshaft structure of the drive connection 43 needs to pass through both the mating opening 312 of the support frame 31 and the clearance hole of the cover plate 32, the design of R = r + 0.1 mm creates a radial clearance of 0.1 mm on one side between them. This small clearance compensates for axial misalignment between the support frame 31 and the cover plate 32 during assembly, preventing crankshaft structure installation interference due to hole misalignment. It also limits the radial wobble amplitude of the crankshaft structure during operation, preventing vibration noise or decreased movement accuracy due to excessive clearance.

[0058] In a specific embodiment, the transmission assembly 2 includes a motor crankshaft 21 and an air guide connecting rod 22. The motor crankshaft 21 is connected to the output end of the drive assembly 1, and the air guide connecting rod 22 is simultaneously hinged to the drive connection part 43 of the motor crankshaft 21 and all the air guide plates 41.

[0059] The motor crankshaft 21 and the air guide connecting rod 22 form a power transmission path through a hinge. One end of the motor crankshaft 21 is rigidly connected to the output shaft of the drive assembly 1, and the other end is designed with an eccentric shaft section. The axis of this eccentric shaft section is parallel to the axis of the output shaft of the drive assembly 1 but has a radial offset. One end of the air guide connecting rod 22 is sleeved on the eccentric shaft section of the motor crankshaft 21 through a bearing or bushing, forming a rotatable hinged connection. The other end of the air guide connecting rod 22 is simultaneously connected to the drive connection part 43 of all the air guide plates 41 through multiple hinge points, and each hinge point is equidistantly distributed along the length direction of the air guide connecting rod 22. In terms of positional relationship, the axis of the motor crankshaft 21 is perpendicular to the axis of the rotating connection part 42 of the air guide plate 41, so that the rotational motion output by the drive assembly 1 is converted into the planar reciprocating motion of the air guide connecting rod 22 through the eccentric shaft section of the motor crankshaft 21, and then the linkage deflection of all the air guide plates 41 is achieved through the multi-point synchronous traction of the air guide connecting rod 22.

[0060] The function of the motor crankshaft 21 is to convert the rotational motion output by the drive assembly 1 into the periodic oscillation of the air guide connecting rod 22. The radial offset of its eccentric shaft section determines the oscillation amplitude of the air guide connecting rod 22. The function of the air guide connecting rod 22 is to synchronously transmit the oscillation motion of the motor crankshaft 21 to the drive connection parts 43 of all air guide plates 41, and to ensure the consistency of the rotation angle of multiple air guide plates 41 through its own rigid structure. When the two work together, the rotation of the motor crankshaft 21 drives the air guide connecting rod 22 to perform planar reciprocating motion. The air guide connecting rod 22 pulls the drive connection parts 43 of all air guide plates 41 simultaneously through multi-point hinges, so that each air guide plate 41 produces synchronous angular displacement around its respective rotation connection part 42 axis, ultimately achieving unified angle adjustment of multiple air guide plates at the air conditioning outlet. This linkage design avoids the complex assembly of traditional independent crank connecting rods, and at the same time ensures the synchronous accuracy of the air guide plate movement through a single-point input and multi-point output transmission method.

[0061] In a specific embodiment, the air guide plate 41 is provided with a limiting rib 44, and the support component 3 is provided with a corresponding limiting baffle 33; when the air guide plate 41 is rotated to the opening limit position, the limiting rib 44 contacts the limiting baffle 33.

[0062] The limiting rib 44 protrudes vertically from the side or end surface of the air guide plate 41, and its extension direction is parallel to the rotation axis of the air guide plate 41. The limiting baffle 33 is fixed inside the opening frame of the support assembly 3, and its position coincides with the end point of the movement trajectory of the limiting rib 44 when the air guide plate 41 rotates to the opening limit. When the air guide plate 41 rotates around the rotating connection part 42 to the maximum opening angle, the end plane of the limiting rib 44 and the contact plane of the limiting baffle 33 are completely in contact, and the two form a surface contact constraint. The installation height of the limiting baffle 33 is slightly lower than the protrusion height of the limiting rib 44, ensuring that only a specific area of ​​the limiting rib 44 bears the load when in contact, avoiding stress on the overall structure of the support assembly 3.

[0063] In a specific embodiment, the contact area between the air guide plate 41 and the support component 3 is coated with a silicone grease layer. The core effect of applying a silicone grease layer to the contact area between the air guide plate 41 and the support component 3 is to optimize the motion performance and structural durability of the air guide plate 41 through lubrication and isolation. The viscous properties of the silicone grease layer can fill the microscopic gaps between the contact surfaces of the air guide plate 41 and the support component 3, reducing dry friction during relative movement and thus lowering the wear rate.

[0064] The air guide plate 41 and the support assembly 3 are made of POM (polyoxymethylene) or glass fiber reinforced nylon. The use of POM or glass fiber reinforced nylon in the air guide plate 41 and support assembly 3 improves the mechanical properties and durability of the air guide plate assembly through the comprehensive material characteristics. POM material has a low coefficient of friction, high rigidity, and excellent wear resistance, which reduces frictional loss at the contact points between the air guide plate 41 and the support assembly 3 during rotation. Its self-lubricating properties also reduce operating noise and prevent increased gaps due to wear after long-term use. Glass fiber reinforced nylon material, through the addition of glass fibers, significantly improves the material's strength, heat resistance, and dimensional stability, ensuring that the support assembly 3 maintains structural rigidity in the high and low temperature alternating environment of air conditioning operation, preventing thermal deformation from affecting the movement accuracy of the air guide plate 41, and enhancing the bending resistance of the air guide plate 41 to withstand airflow impact. Both exhibit excellent fatigue resistance and chemical corrosion resistance, enabling them to withstand long-term erosion from cleaning agents or condensate in humid environments. This reduces component wear, extends service life, and ensures the reliability and smooth operation of the air guide plate assembly under complex working conditions.

[0065] The working process of the air guide plate structure provided in this embodiment is as follows:

[0066] When drive assembly 1 starts, its output shaft drives the motor crankshaft 21 in transmission assembly 2 to rotate. The eccentric shaft section of the motor crankshaft 21 converts the rotational motion output by drive assembly 1 into planar reciprocating motion, driving the air guide connecting rod 22 to oscillate periodically. The air guide connecting rod 22 synchronously pulls the drive connection parts 43 of all air guide plates 41 through multiple hinge points. The drive connection parts 43, as crankshaft structures, are embedded in the mating openings 312 of the support frame 31 and pass through the clearance holes of the cover plate 32. Its eccentric shaft section converts the linear tension of the air guide connecting rod 22 into the rotational torque of the air guide plate 41 about the axis of the rotating connection part 42. The rotating connection part 42 of the air guide plate 41 achieves stable rotation on the support frame 31 through the cooperation of the pin and the bushing 311. The bushing 311 is set on the support frame 31 or integrally formed with the air guide plate 41 to ensure that frictional loss is controllable during rotation. When the air guide plate 41 is deflected by the driving force, its limiting rib 44 moves along the rotation trajectory until the air guide plate 41 reaches the preset opening limit position. At this point, the limiting rib 44 contacts the limiting stop 33 of the support component 3, absorbing kinetic energy through rigid stop and forcibly stopping the rotation, thus precisely controlling the air guide angle. After the support frame 31 and cover plate 32 of the support component 3 are pre-positioned by the square pin 321, they are locked by the fastener to form a closed receiving space. The drive connection part 43 rotates freely in this space. The height h = 1.5r of the matching opening 312 allows for slight tilting of the crankshaft structure to avoid jamming. The clearance of the clearance hole radius R = r + 0.1mm compensates for assembly errors and limits radial wobble. The silicone grease layer at the contact point between the air guide plate 41 and the support frame 31 provides continuous lubrication. Combined with the low friction and high rigidity characteristics of POM or glass fiber reinforced nylon materials, this ensures that the air guide plate 41 maintains smooth movement during long-term high-frequency rotation, while resisting airflow impact and temperature deformation. Ultimately, under the synchronous drive of the transmission component 2, multiple air guide vanes 41 deflect uniformly around their respective rotating connection parts 42 axes, and precisely adjust the airflow direction of the air conditioning outlet through angular linkage. The entire process achieves efficient, stable and durable air guiding control through the integrated drive connection part 43, the split support component 3 and the hard limit mechanism.

[0067] Example 2

[0068] This embodiment provides an air conditioner, such as Figure 11 and Figure 12 As shown, the air conditioner includes the air guide plate structure described in Embodiment 1, and the air guide plate structure is disposed at the air outlet of the air conditioner.

[0069] After applying the air guide plate structure of Example 1, the air conditioner in this embodiment simplifies assembly through integrated design and achieves precise air control through synchronous air guidance.
