Description
Technical Field
[0001] This utility model belongs to the field of air conditioning, specifically relating to a novel air conditioning damping plate for air valves. Background Technology
[0002] In a complex ventilation duct network, the airflow at the outlet closest to the fan may be very high, while the airflow at the farthest outlet may be very low. By adjusting the manually adjustable dampers on each branch pipe, it's possible to "limit" the airflow in the high-volume branch, forcing more air to flow to the low-volume branch. Ultimately, this ensures that the airflow at all outlets in the entire system reaches the design value, guaranteeing that each room receives the expected air volume.
[0003] Existing air conditioning damper damping plates typically consist of a frame, a baffle, and a pivot. The frame is directly installed inside the central ventilation duct, and the baffle is made of aluminum alloy single blades. When the air volume of each branch is adjusted to a large extent, the single blades are prone to generating noise and the air volume regulation is uneven, resulting in poor air conditioning regulation effect.
[0004] In summary, there is an urgent need for a new type of air conditioning damper damping plate to solve the problem that the existing air conditioning damper damping plate baffle uses a single blade for blocking, which easily generates noise during use. Utility Model Content

The connecting plate has multiple pin holes, and a rotating shaft is fixed in the pin holes. A damping plate is fixed between the rotating shafts. A drive plate is provided on one side of the connecting plate. The drive plate is connected to the rotating shaft and then to the moving plate. The moving plate is fixed to the drive plate by a pin. The other end of the drive plate is fixed to the connecting plate.
[0007] Furthermore, the damping plate is composed of a first damping plate and a second damping plate, with a damping connecting plate fixed between the first damping plate and the second damping plate, and the damping connecting plate is fixedly connected to the rotating shaft by a pin.
[0008] Furthermore, the first damping plate and the second damping plate are respectively composed of a snap-fit plate, an air guide plate and a connecting plate, the snap-fit plate, the air guide plate and the connecting plate are integrally formed, and the snap-fit plate of the first damping plate and the connecting plate of the second damping plate are embedded and connected.
[0009] Furthermore, the edge of the damping plate is provided with a slot, the width of which is the same as the width of the first damping plate and the second damping plate, and they are fixedly connected by an inlay method.

[0013] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0014] In this invention, the damping plate is composed of a first damping plate and a second damping plate. The first damping plate and the second damping plate are fixedly connected by interlocking and embedding with each other. When the damping plate rotates, the force is evenly distributed, reducing vibration and noise, and improving the service life and stability of the air valve.
[0015] In this embodiment, the air conditioning damper is used to adjust the air conditioning output volume and is usually composed of one or more metal blades (valve plates). These blades can change their angle manually, electrically or pneumatically, thereby changing the size of the cross-sectional area of the ventilation duct.
[0016] Reference Figures 1-2In this embodiment of the utility model, a novel air conditioning damping plate 102100 is provided, including: an upper frame 101 and a lower frame. The upper frame 101 and the lower frame are connected by a connecting plate 109. The connecting plate 109 is provided with a plurality of pin holes. A rotating shaft 104 is fixed in the pin holes. A damping plate 102 is fixed between the rotating shafts 104. A driving plate 103 is provided on one side of the connecting plate 109. The driving plate 103 is connected to the rotating shaft 104 and then connected to a moving plate 105. The moving plate 105 is fixed with a driving plate 106 by a pin. The other end of the driving plate 106 is fixedly connected to the connecting plate 109.
[0017] Specifically, in the novel air conditioning damper damping plate 102100 provided in this embodiment, the upper frame 101 and the lower frame are the main support structures of the damper, used to fix and install internal components. The upper frame 101 and the lower frame are made of rigid and corrosion-resistant materials, such as aluminum alloy, galvanized steel plate, or engineering plastics. There is one upper frame 101 and one lower frame, and their shapes can be designed as rectangles, circles, or other polygons according to the installation requirements of the damper, and their dimensions can be adjusted according to the diameter of the air duct.
[0018] The connecting plate 109 is a transverse component that connects the upper frame 101 and the lower frame, ensuring the stability of the overall structure. The connecting plate 109 can be fixed to the frame by welding or bolts. The connecting plate 109 is provided with multiple pin holes. The number and position of the pin holes are determined according to the layout of the rotating shaft 104. The rotating shaft 104 is evenly distributed on both sides of the connecting plate 109. After the rotating shaft 104 is installed, the two connecting plates 109 are subjected to balanced forces.
[0019] The rotating shaft 104 is the rotation axis of the damping plate 102. The damping plate 102 can be rotated freely through the rotating shaft 104, thereby changing the flow rate entering the branch and thus achieving the function of regulating the airflow. The rotating shaft 104 is made of wear-resistant and high-strength material, such as stainless steel or carbon steel. The diameter of the rotating shaft 104 is adapted to the pin hole and can be fixed by press fitting or thread.
[0020] The damping plate 102 is a key component for controlling airflow. The opening is changed by rotation. The damping plate 102 is made of lightweight and durable materials, such as aluminum plate or plastic composite material. The shape of the damping plate 102 is usually flat or blade-shaped, and the size matches the internal space of the air valve. In this embodiment, the damping plate 102 is fixed by two composite pieces, and the material is aluminum plate stamping.
[0021] The drive plate 103, the movable plate 105, and the drive plate 106 form a transmission mechanism for manually or automatically controlling the opening and closing of the damping plate 102. The drive plate 103 is connected to the rotating shaft 104 by a key. The movable plate 105 can transmit the power of the drive plate 106 to the drive plate 103. The drive plate 103 drives the rotating shaft 104 to rotate, and the rotating shaft 104 drives the damping plate 102 to change its opening, thereby adjusting the air volume. The movable plate 105 is hinged to the drive plate 106 by a pin. The other end of the drive plate 106 is fixed to the connecting plate 109, forming a lever mechanism.
[0022] By installing a crank on the drive plate 106, the rotation of the drive damping plate 102 can be achieved manually. Alternatively, a displacement sensor can be installed on the rotating shaft 104, and a drive motor can be installed on the drive plate 106. The displacement sensor and the drive motor are linearly connected to a controller. The controller controls the power supply of the drive motor based on the sensor's sensing information and the drive motor's position information, thereby controlling the opening and closing angle of the damping plate and achieving the effect of controlling the air volume.
[0023] The drive plate 103 and the moving plate 105 can be made of metal stamping parts. The drive plate 106 is made of a material with a certain elasticity to buffer the impact of movement. In this embodiment, alloy steel is preferred. During installation, the rotating shaft 104 is inserted into the pin hole and fixed. The damping plate 102 is installed between the rotating shafts 104. The drive plate 103 is keyed to the rotating shaft 104. The moving plate 105 is connected to the drive plate 103 by a pin or bolt. One end of the drive plate 106 is pinned to the moving plate 105, and the other end is fixed to the connecting plate 109, forming a complete transmission chain.
[0024] Understandably, in this embodiment, the air volume is controlled by adjusting the angle of the damping plate 102 to achieve airflow balance and energy saving. The drive mechanism can drive the moving plate 105 to move by driving the drive motor or manually cranking the crank, thereby driving the drive plate 103 and the rotating shaft 104 to rotate and change the angle of the damping plate 102.
[0025] Based on the above structure, the damping plate 102 has two states during use: open and closed. Specifically, when the drive mechanism is activated, the moving plate 105 moves linearly, pulling or pushing the drive plate 103 through the drive plate 106. The drive plate 103 drives the rotating shaft 104 to rotate, and the damping plate 102 on the rotating shaft 104 rotates accordingly. Taking the manual cranking of the drive mechanism to open the damping plate 102 as an example, the manual cranking rotates the drive plate 106 by a certain angle, which drives the moving plate 105 to move. The moving plate 105, through the drive plate 103, causes the rotating shaft 104 to rotate and move by an angle, thereby driving the damping plate 102 to a horizontal state, i.e., the damping plate 102 is in the open state. When the damping plate 102 is in the open state, airflow can pass smoothly. When the damping plate 102 is in the closed state, airflow is blocked, realizing the regulating function of the air valve. This structure is simple and reliable, has high transmission efficiency, and is easy to maintain and install.
[0026] Referring to Figure 3, the damping plate 102 in this embodiment is composed of a first damping plate and a second damping plate. A damping connecting plate is fixed between the first damping plate and the second damping plate, and the damping connecting plate is fixedly connected to the rotating shaft 104 by a pin.
[0027] Specifically, in this embodiment, the damping plate 102 adopts a split design, consisting of a first damping plate and a second damping plate, which are connected by a damping connecting plate in the middle. The first damping plate and the second damping plate can be made of the same material and shape, such as aluminum alloy or plastic injection molding, with a thickness of generally 0.5-2mm. The specific thickness can be selected according to the actual air volume and the ambient temperature difference. In this embodiment, 1mm is preferred.
[0028] The damping plate is a connecting component used to fix the two damping plates and transmit rotational torque. The damping plate is made of alloy steel and formed by stamping. It is fixedly connected to the rotating shaft 104 by pins. The diameter of the pins matches the holes on the rotating shaft 104, ranging from 2-5 mm, and the pins are made of stainless steel. During installation, the first and second damping plates are first fixedly connected by interlocking. After installation, the first and second damping plates are interlocked with the damping plate. Then, the mounting holes on the damping plate are aligned with the rotating shaft 104, and the pins are inserted and locked. The damping plate 102 adopts a split design for easy manufacturing and assembly, as well as for later replacement and installation.
[0029] With the symmetrical arrangement of the first and second damping plates, the damping plate 102 is subjected to uniform force during rotation, which reduces vibration and noise and improves the service life and stability of the air valve.
[0030] In this embodiment, the first damping plate and the second damping plate are respectively composed of a snap-fit plate 107, an air guide plate 108 and a connecting plate 109. The snap-fit plate 107, the air guide plate 108 and the connecting plate 109 are integrally formed, and the snap-fit plate 107 of the first damping plate and the connecting plate 109 of the second damping plate are embedded and connected.
[0031] In this embodiment, the first damping plate and the second damping plate are manufactured by an integral molding process consisting of three parts: a snap-fit plate 107, an air guide plate 108, and a connecting plate 109, respectively. For example, they can be manufactured by injection molding or die casting. The snap-fit plate 107 is used to connect with the connecting plate 109 of the adjacent damping plate. The cross-section of the snap-fit plate 107 is a U-shaped snap-fit. The air guide plate 108 is the main air guiding part. Its shape is a slope to reduce airflow resistance.
[0032] The snap-fit plate 107 of the first damping plate and the connecting plate 109 of the second damping plate are connected by an inlay method, that is, the connecting plate 109 is embedded in the snap-fit plate 107 to form a tight fit. This design does not require additional fasteners and simplifies the assembly process. The thickness of the snap-fit plate 107 and the connecting plate 109 is 1-2mm. The groove width of the connecting plate 109 is slightly smaller than the thickness of the snap-fit plate 107 to produce an interference fit.
[0033] During installation, first align the connecting plate 109 of the first damping plate with the snap-fit plate 107 of the second damping plate, and press it in firmly until it is locked. Then align the connecting plate 109 of the second damping plate with the snap-fit plate 107 of the first damping plate, and press it in firmly to lock it. Then install the whole assembly onto the damping plate. Through the interlocking and interlocking connection, not only is the overall stiffness of the damping plate 102 improved, but also abnormal noise is avoided under the impact of airflow, making it suitable for high wind speed environments.
[0034] The edge of the damping plate is provided with a slot, the width of which is the same as the width of the first damping plate and the second damping plate, and they are fixedly connected by an inlay method.
[0035] Specifically, the damping connecting plate serves as the support base for the damping sheet. Its edge is provided with a slot, which allows for more precise and reliable fixing of the first and second damping sheets. The width of the slot is adapted to the width of the damping sheet. For example, if the width of the damping sheet is 30mm, the width of the slot is also 30mm, with the tolerance controlled within ±0.1mm to ensure tight embedding. In this embodiment, the depth of the slot is generally twice the thickness of the damping sheet. When the damping sheet is embedded in the slot, it can securely fix the damping sheet to the damping connecting plate to provide sufficient fixing force.
[0036] Damping plates are typically made of metal or high-strength plastic. The slots can be machined by milling or molding. During installation, the edges of the first and second damping plates are first inserted into the slots, and then pressure is applied or a tapping tool is used to make them fully embedded. This inlay connection method not only ensures the accurate positioning of the damping plates, but also improves the overall sealing and durability, preventing loosening during long-term use.
[0037] With its slot design, the damping plate 102 is easier to assemble and suitable for automated production lines. It also reduces maintenance costs and ensures that the damper maintains reliable performance under frequent operation.
