Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to an air outlet structure and a vehicle. Background Technology

[0002] In the automotive field, air conditioning vents are key components for cabin environment regulation, and their performance and experience directly affect users' perception of vehicle quality. This is especially true in luxury models, where the requirements for the quietness and tactile feel of the air vents are even more stringent.

[0003] In existing technologies, automotive air conditioning vents often employ a mechanically linked damper button structure. The damper is rotated by the button to open or close the air duct or adjust the airflow. However, the button in this type of structure rebounds too quickly upon release, resulting in a stiff operating feel. Furthermore, the damper is prone to rigid collisions with other structures due to the reverse force of air pressure during rotation, causing abnormal noises and compromising cabin quietness.

[0004] Therefore, it is necessary to provide an improved air outlet structure and vehicle to solve the above problems. Utility Model Content

[0005] This application provides an air outlet structure and vehicle to improve handling and reduce abnormal noise.

[0006] This application discloses an air outlet structure, including a housing, a damper, a button, a connecting component, and a buffer component. An air outlet channel is formed inside the housing. The damper is rotatably disposed within the air outlet channel. The button is slidably mounted on the housing. The connecting component connects the damper and the button. A rack is provided on the button. The buffer component includes a damping gear, which meshes with the rack.

[0007] Furthermore, the buffer assembly also includes a damping bracket fixed outside the housing, the damping bracket and the housing forming an accommodating space, and the damping gear located within the accommodating space; the damping bracket is provided with a slot, and the damping gear is provided with a buckle that cooperates with the slot.

[0008] Furthermore, the damping bracket has a through hole on the wall near the damper, and the rack extends out of the through hole from the accommodating space.

[0009] Furthermore, the connecting assembly includes a pull rod, with the two ends of the pull rod connected to the damper and the button, respectively, and the button drives the damper to rotate via the pull rod.

[0010] Furthermore, the connecting assembly also includes a damper bushing, which includes a first connecting portion connected to the damper and a second connecting portion connected to the pull rod.

[0011] Furthermore, the connecting assembly also includes a limiting member and a swing pin. The limiting member is located between the button and the housing and is fixed to the housing. The limiting member has a locking part and a track groove on the side near the button. One end of the swing pin is fixed relative to the button, and the other end of the swing pin is slidably disposed in the track groove and can abut against the locking part.

[0012] Furthermore, the housing includes a connected upper shell and a lower shell, with the upper shell and the damper located at opposite ends of the lower shell; the button includes a connected button housing and a button base, with the button housing located within a receiving groove in the upper shell and the button base located outside the lower shell.

[0013] Furthermore, the button base is provided with a first abutting wall and a pressing shaft perpendicular to the first abutting wall, the outer side of the lower shell is provided with a second abutting wall, and the button also includes a spring, the spring being sleeved on the pressing shaft and its two ends abutting against the first abutting wall and the second abutting wall respectively.

[0014] Furthermore, the air outlet duct is provided with a lower blade close to the damper and an upper blade away from the damper. Both the lower blade and the upper blade can swing, and their swing directions are perpendicular to each other.

[0015] This application also discloses a vehicle including the air vent structure described above.

[0016] The air vent structure and vehicle described in this application utilize a buffer component and a damping gear and rack meshing design to generate a damping effect when the button is moved. This effectively reduces the speed of button pressing and rebound, improving the stiff feel of the button and enhancing the smoothness and delicacy of operation. Simultaneously, the synergistic effect of the buffer component and connecting components makes the vent rotation process smoother, significantly reducing abnormal noises caused by impacts and contributing to improved cabin quietness.

[0032] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0033] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0034] The mixing blade assembly and food processor of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0035] like Figures 1 to 3 As shown, this application provides an air outlet structure for vehicle air conditioning. The air outlet structure includes a housing 10, an air damper 20, a button 30, a connecting component 40, and a buffer component 50. An air outlet channel 101 is formed inside the housing 10. The air damper 20 is connected to the housing 10 and located inside the air outlet channel 101. The button 30, the connecting component 40, and the buffer component 50 are all connected to the housing 10 and located outside the air outlet channel 101.

[0036] The housing 10 includes an upper housing 11 and a lower housing 12 connected together. The upper housing 11 is located on the side closer to the outside, and the lower housing 12 is located on the side closer to the air conditioning unit. The upper housing 11 is provided with a first ventilation slot 111 and a receiving slot 112, and the lower housing 12 is provided with a second ventilation slot 121. The first ventilation slot 111, the receiving slot 112, and the second ventilation slot 121 are all interconnected. The first ventilation slot 111 and the second ventilation slot 121 are connected and have the same cross-sectional shape, forming an air outlet channel 101. The receiving slot 112 is located on one side of the first ventilation slot 111 and is used to receive the button 30.

[0037] Furthermore, the housing 10 in this embodiment also includes a decorative panel 13, which is fixed to the upper housing 11 and fixed to the side of the upper housing 11 away from the lower housing 12. The decorative panel 13 is provided with a ventilation hole 131 and a receiving hole 132. The ventilation hole 131 is connected to the first ventilation groove 111 and has the same shape, and the receiving hole 132 is connected to the receiving groove 112 and has the same shape.

[0038] The upper shell 11, lower shell 12, and decorative panel 13 can be fixed by snap-fit, screw-fit, a combination of snap-fit ​​and screw-fit, or other fixing methods. This application does not limit this.

[0039] The damper 20 is rotatably disposed within the air outlet duct 101, with the upper housing 11 and the damper 20 located at opposite ends of the lower housing 12. When the damper 20 is open, the cold or warm air generated by the air conditioner can be delivered to the vehicle interior through the air outlet duct 101. When the damper 20 is closed, it blocks the air outlet duct 101, preventing the cold or warm air generated by the air conditioner from being delivered to the vehicle interior.

[0040] Button 30 is slidably mounted on housing 10 and drives damper 20 to rotate during sliding. Button 30 includes a connected button housing 31 and button base 32, with button base 32 located on the side closer to damper 20. Button housing 31 is located within receiving hole 133 and receiving groove 112, and button base 32 is located on the outside of lower housing 12. In use, the damper 20 opens after the button 30 is pressed and released for the first time, and closes after the button 30 is pressed and released again.

[0041] Please refer to the following at the same time Figure 4 and Figure 5 The button base 32 is provided with a first abutting wall 322 and a pressing shaft 323, which are located on the side away from the button housing 31. The pressing shaft 323 extends along the pressing direction of the button 30 and is perpendicular to the first abutting wall 322. A second abutting wall 122 is provided on the outer side of the lower housing 12. The button 30 also includes a spring 33, which is sleeved on the pressing shaft 323 and its two ends abut against the first abutting wall 322 and the second abutting wall 122 respectively, providing the button 30 with the force to rebound after being pressed.

[0042] Please refer to the following at the same time Figure 6 The connecting component 40 connects the damper 20 and the button 30, and the button 30 drives the damper 20 to rotate through the connecting component 40. The connecting component 40 includes a pull rod 41, with its two ends connected to the damper 20 and the button 30 respectively. The button 30 drives the damper 20 to rotate through the pull rod 41. This application directly connects the damper 20 and the button 30 through the pull rod 41, which enables direct force transmission, high transmission efficiency, and simple structure, reduces power loss, ensures that the button 30 can accurately drive the damper 20 to rotate, and improves the response sensitivity of the structure.

[0043] Furthermore, such as Figure 7As shown, in this embodiment, the connecting assembly 40 further includes a damper bushing 42. The damper bushing 42 passes through the lower housing 12 and is connected to both the damper 20 and the pull rod 41. Specifically, the damper bushing 42 includes a first connecting portion 421 and a second connecting portion 422. The first connecting portion 421 is connected to the damper 20, and the second connecting portion 422 is connected to the pull rod 41. Both the second connecting portion 422 and the damper 20 rotate synchronously about the axis of the first connecting portion 421. During the movement of the button 30, the pull rod 41 drives the second connecting portion 422 to move, thereby causing the damper 20 to rotate.

[0044] By setting the damper bushing 42, the compatibility between the damper 20 and the pull rod 41 is enhanced, ensuring smooth and stable rotation, reducing wear between components, and extending service life.

[0045] Furthermore, such as Figure 8 As shown, the connecting assembly 40 also includes a limiting member 43 and a pivot pin 44, used to limit the button 30 after the damper 20 is opened and closed. The limiting member 43 is located between the button 30 and the housing 10 and is fixed to the housing 10. A locking part 431 and a track groove 432 are provided on the side of the limiting member 43 near the button 30. In this embodiment, the track groove 432 is recessed inward from the main body of the limiting member 43, and the locking part 431 is located in the middle of the track groove 432 and protrudes relative to the track groove 432. One end of the pivot pin 44 is fixed relative to the button 30, and the other end is slidably disposed in the track groove 432 and can abut against the locking part 431 to limit the button 30.

[0046] The locking part 431 can limit the excessive movement of the button 30 and prevent the component from being damaged due to overtravel. The track groove 432 provides a stable movement path for the oscillating pin 44, ensuring the consistency of the sliding trajectory of the button 30, improving the stability and accuracy of operation, and improving the user's operating feel.

[0047] Specifically, in this embodiment, the oscillating needle 44 includes an oscillating needle body 441, a first bent portion 442, and a second bent portion 443. The first bent portion 442 and the second bent portion 443 are bent from both ends of the oscillating needle body 441 in a direction perpendicular to the oscillating needle body 441, and their bending directions are opposite. The first bent portion 442 is inserted into a mating hole (not shown in the figure) in the button base 32, and a section of the oscillating needle body 441 near the first bent portion 442 is clamped between the button base 32 and the button housing 31, so that one end of the oscillating needle 44 is fixed to the button 30. The locking portion 431 has a recess on the side away from the button housing 31, and the second bent portion 443 is slidably disposed in the track groove 432 and can move into the recess to abut against the locking portion 431. When the second bend 443 comes into contact with the locking part 431, the locking part 431 restricts the position of the second bend 443, thereby limiting the button 30 and locking the rotation angle of the damper 20.

[0048] like Figure 9 and Figure 10 As shown, the buffer assembly 50 includes a damping gear 51 and a damping bracket 52. A rack 321 is provided on the button 30, and the damping gear 51 meshes with the rack 321. Specifically, in this embodiment, the rack 321 is disposed on the button base 32 and located on the side of the actuation shaft 323 away from the air outlet channel 101. The damping gear 51 is a viscous silicone oil rotary damper, which can provide controllable resistance torque during rotation.

[0049] When button 30 is released, button base 32 drives rack 321 to move, and rack 321 drives damping gear 51 to rotate. Damping gear 51 generates reverse torque, slowing down the movement speed of rack 321, thereby reducing the rebound speed of button 30 by 60% to 80%. At the same time, since the rotation speed of damper 20 also slows down with the movement speed of button 30, it can release wind pressure during rotation, reducing the impact energy between damper 20 and other components of the air outlet structure by more than 90%, which can reduce or even completely eliminate abnormal noise and improve cabin quietness.

[0050] The damping bracket 52 is fixed to the outside of the housing 10. The damping bracket 52 and the housing 10 form an accommodating space, within which the damping gear 51 is located. The damping bracket 52 provides a relatively enclosed environment for the damping gear 51, effectively preventing dust intrusion and external interference, ensuring reliable and stable damping performance. The damping bracket 52 is provided with a slot 521, and the damping gear 51 is provided with a buckle 511 that mates with the slot 521. In this embodiment, there are two buckles 511, located on both sides of the damping gear 51, and there are also two slots 521.

[0051] Furthermore, to achieve a compact layout of the air outlet structure, part of the button base 32 is also located within the accommodating space. The damping bracket 52 has a through hole 522 on its wall near the damper 20, and the rack 321 extends outward from the through hole 522 from within the accommodating space to avoid structural interference between the rack 321 and the damping bracket 52, thereby improving the stability and reliability of the transmission.

[0052] Furthermore, such as Figure 3 and Figure 11As shown, in the air outlet structure of this application, the air outlet channel 101 is provided with a lower blade 61 near the damper 20 and an upper blade 62 away from the damper 20. Both the lower blade 61 and the upper blade 62 can swing, and their swing directions are perpendicular to each other, which can realize multi-angle and multi-directional air outlet adjustment, expand the air supply range, meet the air supply needs of different users, and effectively improve the comfort and flexibility of use. In this embodiment, the lower blade 61 is arranged along the width direction of the air outlet channel 101, and there are multiple lower blades. The upper blade 62 is arranged along the length direction of the air outlet channel 102, and there is one upper blade.

[0053] Furthermore, the air outlet duct 101 is also equipped with a connecting rod 63, a fork 64, a knob 65, a knob damper 66, a bushing damper 67, a tick pin 68, and a sealing sponge 69. The connecting rod 63 connects several lower blades 61 to ensure the synchronous oscillation of the lower blades 61. The fork 64 and the knob 65 are used to adjust the oscillation direction of the lower blades 61 and the upper blades 62. The fork 64 is connected to the lower blades 61 and the knob 65 respectively, and the knob 65 is set on the upper blades 62. When the knob 65 slides along the extension direction of the upper blades 62, it can drive the lower blades 61 to oscillate through the fork 64, thereby controlling the airflow direction of the lower blades 61. When the knob 65 moves along the extension direction of the lower blades 61, it can drive the upper blades 62 to oscillate, thereby controlling the airflow direction of the upper blades 62.

[0054] A damper 66 is located inside the toggle switch 65, and a bushing damper 67 is located at the connection between the upper blade 62 and the housing 10. The toggle damper 66 and bushing damper 67 reduce the rotational speed of the lower blade 61 and the upper blade 62, making the airflow adjustment process smoother. A tick pin 68 engages with a corresponding slot or groove when the lower blade 61 or the upper blade 62 rotates to a specific position, producing a mechanical beep to allow the user to intuitively perceive the blade's adjustment status. A sealing sponge 69 is fixed to the lower housing 12 and located near the damper 20, serving a sealing function to prevent air leakage from the lower housing 12.

[0055] This application also provides a vehicle including the air vent structure described above.

[0056] The air vent structure and vehicle of this application, by incorporating a buffer component 50 and utilizing the meshing design of a damping gear 51 and a rack 321, generate a damping effect when the button 30 moves. This effectively slows down the pressing and rebound speed of the button 30, improving the stiff feel of the button 30 and enhancing the delicacy and smoothness of the operation, achieving a three-stage advanced feel of "slow start, fast press, and soft rebound." Simultaneously, through the synergistic effect of the buffer component 50 and the connecting component 40, the rotation of the damper 20 is made smoother, significantly reducing abnormal noises caused by impacts and contributing to improved cabin quietness.

[0057] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
