Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an air outlet assembly for engineering machinery and agricultural machinery. Background Technology

[0002] Construction machinery and agricultural machinery are important components of the equipment industry and are essential mechanical equipment for comprehensive mechanized construction projects. They are mainly used in transportation construction, energy industry construction and production, raw material industry construction and production such as mining, agricultural, forestry and water conservancy construction, industrial construction, industrial environmental protection, industrial and civil buildings, urban construction, and environmental protection.

[0003] For large cabs equipped with air conditioning, the air outlet structure is a standard component widely used in construction machinery and agricultural machinery. It typically includes an air outlet body with an air outlet and a baffle plate installed inside the air outlet. Airflow flows through the air outlet and out to the outside of the air conditioner. The size of the air outlet opening can be adjusted by changing the angle of the baffle plate relative to the air outlet body.

[0004] In the existing technology, whether it is construction machinery or agricultural machinery, the interior of the equipment often adopts a structure in which several air outlets share a main air supply pipe and air is delivered through a distribution chamber. When the main air supply pipe delivers air to each air outlet, there is no flow guiding device. The air outlet structure has an air outlet body and a baffle plate set in the air outlet. The airflow flows through the air outlet and flows out to the outside of the air conditioner. The baffle plate adjusts the opening size of the air outlet by changing the angle relative to the air outlet body. Moreover, the air outlet device does not have a noise reduction device, the movement of the parts is not stable, and it is easy to generate vibration and abnormal noise.

[0005] In existing technologies, most air outlets, airflow direction adjustment, and airflow strength adjustment rely on traditional mechanical touches, which are prone to friction noise, resulting in an unsatisfactory user experience and failing to improve the overall quality.

[0006] In existing technologies, most air outlets do not have a multi-directional adjustment structure in the outer cover to adjust the airflow direction, nor do they hide the damper blades in the internal air duct. Most damper blades are integrated with the outer cover, which is not only unsightly but also results in an unsatisfactory customer experience and fails to improve the overall quality.

[0007] In the existing technology, especially in the cabs of excavators and loaders, there is a front control box that blows air onto the face and windshield. Due to the steering gear and internal space, there are high requirements for the size of the air vents. The bulges are large and affect the aesthetics of the front control box.

[0008] In existing technologies, especially in the cabs of medium and large excavators and loaders, shoulder and back air vents are installed in the rear C-pillar. Due to space constraints within the C-pillar, the size of these vents is critical, resulting in large protrusions that negatively impact the aesthetics of the C-pillar.

[0009] In the existing technology, the interior space of the front control box of the cab is relatively small, and electrical components such as display screen wiring harnesses will also occupy some space, leaving little space for air vents and air ducts, which makes the internal structure layout of the control box difficult. Utility Model Content

[0010] The purpose of this utility model is to provide an air outlet assembly for engineering machinery and agricultural machinery, which solves the problems of multi-directional air outlet adjustment and the occupation of front control box and C-pillar space. While improving practicality and aesthetics, the damper blades are hidden inside the air duct. Compared with traditional engineering machinery air outlets, it is smaller and more refined while ensuring functionality and strength.

[0011] To achieve the above objectives, this utility model provides the following technical solution: an air outlet assembly for engineering machinery and agricultural machinery, comprising an air outlet body, an air outlet inner ring rotatably mounted on the upper inner side of the air outlet body; a pair of air outlet knobs slidably mounted on the upper part of the air outlet inner ring, with a pair of knob bright strips correspondingly mounted above the knobs; a knob damping pad mounted on the inner side of the air outlet knobs; an air outlet slide rail mounted on the inner side of the air outlet inner ring, with a fork claw connected below the slide rail; a blade assembly rotatably mounted on the inner shaft hole of the air outlet body via a rotating shaft, with a connecting rod for synchronously driving each blade connected below the blade assembly; and a positioning spring pin and a damping component provided between the air outlet body and the air outlet inner ring.

[0012] Preferably, a sponge strip is provided on the lower outer side of the air outlet body to reduce assembly noise and air leakage.

[0013] Preferably, the blade group includes a first blade, a second blade, and a third blade, and when closed, the blades are arranged in a straight line and hidden inside the air outlet body.

[0014] Preferably, the air outlet knob is inserted into the inner side of the air outlet inner ring and is locked with the air outlet slide rail by the knob damping pad to form a sliding adjustment component.

[0015] Preferably, a distance limiting mechanism is provided on the inner side of the inner ring of the air outlet to limit the sliding distance of the air outlet knob.

[0016] Preferably, the damping component includes a first damping pad and a second damping pad, used to improve the motion feel.

[0017] Preferably, the outer side of the air outlet body is provided with an elastic snap-fit ​​mechanism for quick assembly and disassembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The multi-directional adjustment mechanism, consisting of an inner ring of the air outlet, a pair of air outlet knobs, a pair of knob light strips, a blade assembly, a connecting rod, an air outlet slide rail, and a fork claw, enables coordinated adjustment of the airflow direction and volume of the air conditioner outlet. Through a precise mechanical transmission system, users can achieve accurate airflow control with simple operation. 2. By adding a damping pad to the inside of the air outlet knob, making it softly contact the inner ring of the air outlet, the feel of opening and closing the air outlet is improved and noise is reduced; a damping pad and a positioning spring pin are provided between the inner ring of the air outlet and the air outlet body to improve the feel of adjusting the air outlet direction, improve the feel of adjusting the damper and reduce noise.

[0019] 3. By using the inner ring of the air outlet, a pair of air outlet knobs, a pair of knob bright strips, blade assembly, connecting rod, air outlet slide rail, and shift fork claw, practicality and aesthetics are improved. When the air damper is in the closed state, the lower blades of the air damper are hidden inside the air outlet body. Compared with the air outlets of traditional engineering machinery and agricultural machinery, the air outlets are smaller and more refined while ensuring functionality and strength.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, an air outlet assembly for engineering and agricultural machinery includes an air outlet body. An inner ring is rotatably mounted on the upper inner side of the air outlet body, and a damping pad effectively provides damping. A pair of air outlet knobs are slidably mounted above the inner ring, with a pair of knob strips correspondingly mounted above each knob. A damping pad is mounted inside each knob, and an air outlet slide rail is mounted inside the inner ring, with a fork connected below the slide rail. A blade assembly is rotatably mounted on the inner shaft hole of the air outlet body via a rotating shaft, and a connecting rod for synchronously driving each blade is connected below the blade assembly. A positioning spring pin and a damping component are provided between the air outlet body and the inner ring. The inner ring 2, a pair of air outlet knobs 3, a pair of knob strips 4, the blade assembly, the connecting rod 8, the air outlet slide rail 9, and the fork 10 constitute an air conditioning outlet air direction and air volume adjustment structure.

[0024] Specifically, a sponge strip 15 is provided on the lower outer side of the air outlet body 1. By providing the sponge strip 15, abnormal noise and air leakage are avoided between the air outlet and the air duct when it is assembled into the interior body.

[0025] Specifically, the blade assembly includes a first blade 5, a second blade 6, and a third blade 7. When closed, the first blade 5, the second blade 6, and the third blade 7 are arranged in a straight line and hidden inside the air outlet body 1.

[0026] The connecting rod 8 is installed below the first blade 5, the second blade 6, and the third blade 7. The rotating shafts below the first blade 5, the second blade 6, and the third blade 7 are locked in place with the shaft holes of the connecting rod 8. Both ends of the connecting rod 8 are installed inside the air outlet body 1. This enables the synchronous rotation of each blade in the blade assembly. The blade assembly and the connecting rod 8 constitute the damper assembly of this utility model.

[0027] Specifically, the damping component includes a first damping pad 11 and a second damping pad 12. The first damping pad 11 and the second damping pad 12 are installed on the lower inner side of the air outlet body 1. This improves the motion feel and avoids damage to the air outlet caused by improper operation.

[0028] Specifically, the positioning spring pin 14 includes a metal cap and a spring, and the positioning spring pin 14 is located between the inner side of the air outlet body 1 and the lower side of the inner ring 2 of the air outlet.

[0029] In this utility model, a multi-directional adjustment mechanism consisting of an inner ring 2 for the air outlet, a pair of air outlet knobs 3, a pair of knob strips 4, a blade assembly, a connecting rod 8, an air outlet slide rail 9, and a fork claw 10 can be used to adjust the direction and air volume of the air outlet of the air conditioner. By sliding the air outlet knob 3, the air outlet slide rail 9 and the fork claw 10 are driven to rotate the second blade 6, and the connecting rod 8 drives the other blades to rotate, thereby opening or closing the damper. This improves the quality of stepless adjustment of the air outlet and facilitates assembly.

[0030] Furthermore, a distance limiting mechanism 16 is provided on the inner side of the air outlet knob 3 and the inner ring 2 of the air outlet, and the sliding distance of the air outlet knob 3 is adapted to the distance limiting mechanism 16. An angle limiting mechanism 17 is provided between the inner ring 2 of the air outlet and the air outlet body 1, and the rotation angle of the inner ring 2 of the air outlet is adapted to the angle limiting mechanism 17.

[0031] Multiple elastic snap-fit ​​mechanisms 18 are provided on the outer side of the elastic snap-fit ​​mechanism 18, so that the air outlet body 1 can be quickly assembled with the counterpart.

[0032] The usage process of this utility model is described below: 1. The user slides the air outlet knob 3 horizontally with their finger, and the air outlet knob 3 moves smoothly on the guide rail of the inner ring 2. At this time, the knob damping pad 13 installed in the groove on the inside of the knob generates appropriate frictional resistance with the inner wall of the inner ring 2 of the air outlet, providing the user with clear tactile feedback.

[0033] 2. The sliding of the air outlet knob 3 drives the air outlet slide rail 9 to move synchronously through its bottom connecting structure. The displacement of the fork pawl 10 directly acts on the rotation axis of the second blade 6, driving the second blade 6 to rotate around its axis. Since the connecting rod 8 links the first blade 5, the second blade 6, and the third blade 7 together, the rotation of the second blade 6 is synchronously transmitted to the first blade 5 and the third blade 7 through the connecting rod 8, realizing the synchronous opening and closing of all blades. During the sliding process, the distance limiting mechanism 16 set on the inner side of the inner ring 2 of the air outlet limits the sliding stroke of the air outlet knob 3 to prevent excessive sliding from causing damage to the mechanism. When sliding to the maximum or minimum position, the limiting mechanism provides a clear stopping sensation.

[0034] 3. The user holds the inner ring 2 of the air outlet and applies a rotational force, causing it to rotate above the inner side of the air outlet body 1. At this time, the metal cap of the positioning spring pin 14 and the positioning groove on the lower side of the inner ring 2 of the air outlet generate relative movement. During the rotation, the first damping pad 11 and the second damping pad 12 generate uniform frictional damping with the contact surface of the air outlet body 1, ensuring smooth rotation without shaking. When rotated to a specific angle, the spring of the positioning spring pin 14 is compressed and quickly returns to its original position, emitting a clear "tick" sound, providing clear positioning feedback. This achieves the adjustment of the airflow direction.

[0035] In this invention, the user can simultaneously adjust both airflow and direction: first, slide the dial to adjust the airflow, then rotate the inner ring to precisely control the direction. The two adjustment functions do not interfere with each other and can be operated independently. When it is necessary to completely close the air outlet, slide the air outlet dial 3 to the closed position. At this time, the first blade 5, the second blade 6, and the third blade 7 rotate to a fully closed state under the drive of the connecting rod 8. All blades are arranged in a straight line and completely hidden inside the air outlet body 1, achieving an aesthetically pleasing concealment effect. Throughout the entire operation, the sponge strip 15 on the outside of the air outlet body 1 always ensures a tight seal at the duct interface, preventing air leakage and vibration noise. Simultaneously, each damping element effectively absorbs the impact energy of moving parts, extending their service life.
