Description

Technical Field

[0001] This invention relates to the field of automotive interior parts technology, and in particular to a four-bar linkage damping adjustable air vent. Background Technology

[0002] With the overall development of the automotive industry, the design trends of automotive air conditioning vents have undergone tremendous changes. Essentially, an air vent is a functional component that needs to meet the performance engineering requirements of automotive air conditioning. However, with the development of the times and changes in consumer aesthetics, air vents, which are within the passenger's field of vision, have gradually acquired the attributes of interior and exterior components. Styling designers also focus on their design to meet aesthetic demands. In recent years, air vents have increasingly leaned towards a minimalist design style, with traditional barrel-shaped and multi-blade air vents gradually being replaced by simpler single-blade and concealed air vents.

[0003] Compared to traditional air outlets, single-blade air outlets are smaller and simpler in structure, facilitating the spatial arrangement of surrounding components and improving the appearance of the outlet. However, single-blade air outlets also have certain drawbacks. Because this type only has a single blade, it cannot achieve a damping effect through the friction between the blade and the blade connecting rod. Damping is usually achieved using a silicone damping block structure at the blade pivot or damping structures on both sides of the blade. If limited by design or space constraints, these two methods cannot be implemented or can only be implemented in localized areas. Even relying on the friction between the shaft and the hole, it is still difficult to achieve the ideal damping effect for adjusting the blade's vertical movement. Furthermore, as usage time and frequency increase, the damping sensation provided by the friction between the shaft and the hole deteriorates due to the decrease in operating force. Summary of the Invention

[0004] The purpose of this invention is to provide a four-bar linkage damping adjustable air outlet to address the problem that the damping sensation brought about by the friction between the holes and shafts deteriorates due to the decrease in operating force when the usage time and frequency of existing air outlet blades increase.

[0005] To achieve the above objectives, the present invention provides a four-bar linkage damping adjustable air outlet, which includes: an air outlet housing, a blade assembly and a damping component, wherein the air outlet housing is provided with an avoidance notch, and mounting plates are respectively provided on both sides of the avoidance notch;

[0006] The blade assembly is disposed inside the air outlet housing. The blade assembly includes an upper blade, a lower blade, and a blade fixing seat. Blade fixing seats are respectively provided at both ends of the upper blade. The blade fixing seats are detachably connected to the air outlet housing. A lower blade is provided below the upper blade. The lower blade is rotatably connected to the air outlet housing and is connected to the upper blade.

[0007] The damping component includes a first link, a second link, a third link, and a fourth link. The first link is fixedly connected to the upper blade. One end of the second link is connected to the first link, and the other end of the second link passes through the clearance notch and connects to the third link. The end of the third link away from the second link is connected to the fourth link. The fourth link is rotatably connected to the mounting plate. A damping element is provided on the fourth link, and the damping element is provided on the mounting plate.

[0008] As a further description of the above technical solution:

[0009] One end of the mounting plate has a first slot, and the damping element is engaged in the first slot.

[0010] As a further description of the above technical solution:

[0011] The damping element has a first through hole, and the fourth connecting rod passes through the first through hole. The damping element is made of rubber.

[0012] As a further description of the above technical solution:

[0013] The air vent housing has a second slot at each end, and the blade fixing seat is engaged in the second slot.

[0014] As a further description of the above technical solution:

[0015] The air outlet housing is provided with a second through hole, which is connected to the second slot. The blade fixing seat is provided with a plug-in block, which is plugged into the second through hole.

[0016] As a further description of the above technical solution:

[0017] The blade mounting base is provided with a first mounting hole, and the upper blade is provided with a second mounting hole. A rotating shaft is installed in the first mounting hole and the second mounting hole.

[0018] As a further description of the above technical solution:

[0019] The blade holder is provided with a first protrusion, and the first protrusion is provided with a first inclined surface. The upper blade is provided with a second protrusion, and the second protrusion is provided with a second inclined surface that matches the first inclined surface.

[0020] As a further description of the above technical solution:

[0021] A lever is provided on the upper blade, and the lever is connected to the lower blade.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, by adding a first link, a second link, a third link, a fourth link, and a damping element to the air vent housing, the first link, the second link, the third link, and the fourth link form a four-bar linkage mechanism. When the upper blade moves, the upper blade can drive the fourth link to rotate through the first link, the second link, and the third link. Under the action of the damping element, the fourth link squeezes the damping element during rotation, thereby generating friction and forming resistance that hinders rotation. This allows the fourth link to provide stable resistance during rotation, allowing the blade assembly to remain smoothly at any position, while absorbing impact, reducing noise, and improving user experience and lifespan.

[0024] 2. In this invention, the upper blade is mounted on the air outlet housing via two blade fixing seats. The blade fixing seats are fixed to the air outlet housing by plugging in, which facilitates the installation and disassembly of the upper blade and reduces the assembly difficulty. A first protrusion and a second protrusion are provided at the contact point between the upper blade and the blade fixing seat. The first protrusion and the second protrusion are in contact through a first inclined surface and a second inclined surface. During rotation, the first protrusion and the second protrusion can always be in contact, which serves as a damping effect. Attached Figure Description

[0046] Specifically, the damping member 35 is provided with a first through hole 7, the fourth connecting rod 34 passes through the first through hole 7, and the damping member 35 is made of rubber.

[0047] Specifically, a toggle switch 16 is provided on the upper blade 21, and the toggle switch 16 is connected to the lower blade 22.

[0049] By adding a first link, a second link, a third link, a fourth link, and a damping element to the air outlet housing, the first link, the second link, the third link, and the fourth link form a four-bar linkage mechanism. When the upper blade moves, the upper blade can drive the fourth link to rotate through the first link, the second link, and the third link. Under the action of the damping element, the fourth link squeezes the damping element during rotation, thereby generating friction and forming resistance that hinders rotation. This allows the fourth link to provide stable resistance during rotation, allowing the blade assembly to smoothly stop at any position, while absorbing impact, reducing noise, and improving the user experience and lifespan.

[0050] The upper blade is mounted on the air outlet housing via two blade mounting brackets. The blade mounting brackets are fixed to the air outlet housing by plugging in, which facilitates the installation and removal of the upper blade and reduces the assembly difficulty.
