Description

Technical Field

[0001] This utility model relates to automotive air vents, specifically to an air vent assembly structure based on passenger vehicles. Background Technology

[0002] Automotive air conditioning vents are key components of the car interior, directing processed airflow to specific areas to achieve a comfortable driving environment. Currently, mainstream vent assemblies on the market typically offer two degrees of freedom for adjustment: vertical swaying by moving the air guide vanes to change the vertical angle of the airflow; and horizontal swaying by rotating the vent grille horizontally to change the horizontal angle of the airflow. While existing structures can meet basic airflow guidance requirements, when the degrees of freedom in both directions are moved to their limits, there are unreachable "dead zones" in airflow, preventing the achievement of 360-degree airflow guidance. Utility Model Content

[0003] The purpose of this utility model is to provide an air vent assembly structure based on passenger vehicles. The technical problem to be solved is how the air vent assembly can achieve 360-degree air delivery without dead angles.

[0004] This utility model is achieved through the following technical solution:

[0005] An air vent assembly structure based on passenger vehicles includes an outer shell, an inner shell, and a rotating component.

[0006] One end of the aforementioned outer casing is provided with a limiting member, which has a first central hole; the aforementioned rotating component extends into the outer casing through the first central hole;

[0007] The inner shell is fitted inside the outer shell, and a rotating component extending into the outer shell is connected to one end of the inner shell; when the inner shell is subjected to force, the inner shell is rotated by the rotating component.

[0008] By incorporating a rotating component, the inner casing can be rotated, overcoming the limitations of traditional air vents that can only be adjusted in two directions: up and down, left and right. Driven by this component, the inner casing rotates in all directions, allowing airflow to be directed in any direction, regardless of the original airflow angle. This solves the problem of existing air vent assemblies failing to cover "dead zones," achieving 360-degree airflow without blind spots and providing a more comprehensive and comfortable airflow experience for passengers.

[0009] Furthermore, the aforementioned rotating assembly includes a support portion, a rotating portion, and a connecting sleeve, with the support portion and the rotating portion connected via the connecting sleeve;

[0010] One end of the aforementioned support part is provided with a sphere, and the other end is connected to a limiting member; one end of the aforementioned rotating part is provided with a first spherical crown groove, and the other end is connected to the inner shell; the aforementioned sphere is fitted inside the first spherical crown groove, the outer wall of the sphere contacts the groove wall of the first spherical crown groove, and the rotating part rotates around the sphere;

[0011] The connecting sleeve is provided with a spherical groove. The sphere and one end of the rotating part provided with the first spherical crown groove are fitted into the spherical groove, and the outer wall of the rotating part of the spherical groove is in contact with the spherical groove wall of the connecting sleeve.

[0012] Achieving flexible multi-angle rotation: The rotating part, through the cooperation of the first spherical crown groove and the spherical body of the supporting part, and the containment and constraint of the spherical groove of the connecting sleeve, enables the rotating part to rotate flexibly around the sphere in multiple directions. This provides a stable and flexible structural basis for the rotation of the inner shell, thereby achieving 360-degree air supply without dead angles. For example, in actual use, no matter which specific angle the user needs to direct the airflow, the rotating part can be rotated to adjust the inner shell to the corresponding position, eliminating air supply "dead angles".

[0013] The spherical groove of the connecting sleeve not only accommodates the sphere and the rotating part, but also provides additional support and stability to the entire rotating assembly through the contact between its groove wall and the outer wall of the rotating part. During rotation, the spherical groove can limit the swaying of the rotating part, ensure the smoothness of rotation, avoid deviation in the air supply direction caused by structural instability, and ensure the accuracy and reliability of air supply.

[0014] Furthermore, the aforementioned rotating part includes an inner knob and an outer knob, with the inner knob fitted inside the outer knob; the first spherical crown groove is provided on the inner knob, and the outer knob is provided with a second spherical crown groove;

[0015] The inner knob, with the first spherical groove at one end, is fitted into the second spherical groove. The outer wall of the inner knob fitted into the second spherical groove contacts the groove wall of the second spherical groove, and the outer knob rotates around the inner knob. The outer wall of the outer knob fitted into the spherical groove contacts the groove wall of the connecting sleeve.

[0016] Furthermore, the aforementioned outer knob is connected to the inner housing. The outer knob drives the inner housing to rotate, and the rotation of the inner knob can drive the rotation of the outer knob, so that the final rotation direction of the inner housing is the combined direction of the rotation of the inner and outer knobs.

[0017] The inner knob achieves rotation within a certain range by engaging with the ball of the support part through the first spherical groove; the outer knob is fitted around the inner knob and can rotate around it, while the outer knob can also move within the spherical groove of the connecting sleeve. The multi-layered rotating structure increases the degree of freedom of movement of the entire rotating assembly.

[0018] Since the inner knob can drive the outer knob to rotate, and the outer knob can further rotate based on the inner knob, users can control the airflow angle by fine-tuning either the inner or outer knob when adjusting the airflow direction. Rotating the inner knob can initially adjust the general direction of the airflow, while rotating the outer knob can further fine-tune it, guiding the airflow to the desired position. This step-by-step adjustment improves the accuracy of the airflow direction adjustment.

[0019] The spherical groove of the connecting sleeve constrains and supports the outer knob, while the second spherical groove of the outer knob also provides some restriction and stability to the inner knob. During rotation, the multi-layered nested structure mutually restrains each other, reducing unnecessary shaking of the components.

[0020] Furthermore, the outer wall of the inner knob is provided with a protrusion, which abuts against the end of the outer knob by a sealing ring.

[0021] The aforementioned connecting sleeve can initially fill the gap between the ball and the rotating part, and the sealing ring can further fill the gap between the outer knob and the inner knob, preventing airflow from leaking out of the rotating assembly, so that more airflow can be sent out in the set direction, avoiding the reduction of airflow and deviation of airflow direction caused by air leakage, thereby improving airflow efficiency.

[0022] Furthermore, the aforementioned limiting component includes a limiting sleeve and a limiting plate. The limiting sleeve is connected to the outer shell through the limiting plate, and the rotating component is sleeved inside the limiting sleeve.

[0023] The inner shell is provided with a second central hole, and the rotating part of the limiting sleeve extending out is inserted into the second central hole;

[0024] The outer diameter of the end of the limiting sleeve extending into the outer shell gradually decreases; the inner diameter of the end of the second central hole near the rotating part gradually increases.

[0025] When the rotating part rotates from the central axis of the first central hole to any direction by a preset angle, the inner wall of the second central hole abuts against the outer wall of the limiting sleeve.

[0026] The outer diameter of the limiting sleeve gradually decreases, and the inner diameter of the second center hole gradually increases. Combined with the abutment of their sidewalls when the rotating part rotates to a preset angle, this sets a clear boundary for the rotation range of the rotating part. The limiting sleeve and the limiting plate provide stable support and fixation for the rotating assembly.

[0027] Furthermore, an operation knob is provided at one end of the inner knob that extends out of the second central hole.

[0028] Users can apply force to the inner housing using the aforementioned operating knob to rotate the inner housing.

[0029] Furthermore, the aforementioned inner shell is provided with blades.

[0030] Airflow passes through the gaps between adjacent blades and is blown out; the blades can be tilted and set inside the inner casing.

[0031] Furthermore, a damper is connected to the side of the aforementioned rotating assembly away from the inner housing.

[0032] The airflow is regulated by the aforementioned dampers.

[0033] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0034] By incorporating a rotating component, the inner casing can be rotated, overcoming the limitations of traditional air vents that can only be adjusted in two directions: up and down, left and right. Driven by this component, the inner casing rotates in all directions, allowing airflow to be directed in any direction, regardless of the original airflow angle. This solves the problem of existing air vent assemblies failing to cover "dead zones," achieving 360-degree airflow without blind spots and providing a more comprehensive and comfortable airflow experience for passengers.

Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0045] First embodiment:

[0046] Combination Figure 1 , Figure 2 and Figure 4 An air vent assembly structure based on passenger vehicles includes an outer shell 1, an inner shell 2, and a rotating component 4.

[0047] One end of the outer shell 1 is provided with a limiting member 6, which has a first central hole 63; the rotating component 4 extends into the outer shell 1 through the first central hole 63.

[0048] The inner shell 2 is fitted inside the outer shell 1, and the rotating component 4, which extends into the interior of the outer shell 1, is connected to one end of the inner shell 2; when the inner shell 2 is subjected to force, the inner shell 2 is rotated by the rotating component 4.

[0049] By incorporating a rotating component 4 to allow the inner housing 2 to rotate, the limitations of traditional air outlets, which can only be adjusted in two directions (up / down and left / right), are overcome. Driven by the rotating component 4, the inner housing 2 rotates in all directions, freeing the airflow from fixed-direction adjustments. Regardless of the original airflow angle, the rotation of the inner housing 2 can guide the airflow in any direction, solving the problem of existing air outlet assemblies failing to cover "dead zones" in air delivery. This achieves 360-degree air delivery without dead zones, providing a more comprehensive and comfortable airflow experience for drivers and passengers.

[0050] Specific implementation examples, combined with Figures 3 to 5 The rotating component 4 includes a support part 42, a rotating part 41 and a connecting sleeve 46, and the support part 42 and the rotating part 41 are connected by the connecting sleeve 46.

[0051] One end of the support part 42 is provided with a ball 43, and the other end is connected to the limiting member 6; one end of the rotating part 41 is provided with a first spherical crown groove 47, and the other end is connected to the inner shell 2; the ball 43 is sleeved in the first spherical crown groove 47, the outer wall of the ball 43 contacts the groove wall of the first spherical crown groove 47, and the rotating part 41 rotates around the ball 43.

[0052] The connecting sleeve 46 is provided with a spherical groove. One end of the sphere 43 and the rotating part 41 provided with the first spherical crown groove 47 are fitted inside the spherical groove, and the outer wall of the rotating part 41 fitted in the spherical groove contacts the spherical groove wall of the connecting sleeve 46.

[0053] Achieving flexible multi-angle rotation: The rotating part 41, through the cooperation of the first spherical crown groove 47 and the sphere 43 of the support part 42, and the spherical groove of the connecting sleeve 46 accommodating and constraining both, allows the rotating part 41 to rotate flexibly around the sphere 43 in multiple directions. This provides a stable and flexible structural basis for the rotation of the inner shell 2, thereby achieving 360-degree air supply without dead angles. For example, in actual use, no matter which specific angle the user needs to direct the airflow, the inner shell 2 can be adjusted to the corresponding position by rotating the rotating part 41, eliminating air supply "dead angles".

[0054] The spherical groove of the connecting sleeve 46 not only accommodates the sphere 43 and the rotating part 41, but also provides additional support and stability to the entire rotating assembly 4 through the contact between its groove wall and the outer wall of the rotating part 41. During rotation, the spherical groove can limit the swaying of the rotating part 41, ensuring the smoothness of rotation, avoiding deviation in the air supply direction caused by structural instability, and ensuring the accuracy and reliability of air supply.

[0055] Second embodiment:

[0056] Based on the first embodiment, combined with Figures 3 to 5 The rotating part 41 includes an inner knob 44 and an outer knob 45, with the inner knob 44 sleeved inside the outer knob 45; the first spherical crown groove 47 is provided on the inner knob 44, and the outer knob 45 is provided with a second spherical crown groove.

[0057] The inner knob 44 is provided with a first spherical groove 47 at one end, which is fitted into the second spherical groove. The outer wall of the inner knob 44 fitted into the second spherical groove contacts the groove wall of the second spherical groove. The outer knob 45 rotates around the inner knob 44. The outer wall of the outer knob 45 fitted into the spherical groove contacts the groove wall of the connecting sleeve 46.

[0058] In a specific embodiment, the outer knob 45 is connected to the inner housing 2. The outer knob 45 drives the inner housing 2 to rotate, and the inner knob 44, when rotating, can drive the outer knob 45 to rotate, so that the final rotation direction of the inner housing 2 is the direction resulting from the superposition of the rotations of the inner knob 44 and the outer knob 45.

[0059] The inner knob 44 is engaged with the ball 43 of the support part 42 through the first spherical crown groove 47 to achieve a certain range of rotation; the outer knob 45 is sleeved on the inner knob 44 and can rotate around it, while the outer knob 45 can also move in the spherical groove of the connecting sleeve 46. The multi-layer rotation structure increases the degree of freedom of movement of the entire rotating assembly 4.

[0060] Since the inner knob can drive the outer knob 45 to rotate, and the outer knob 45 can be further rotated based on the inner knob 44, the user can control the air supply angle by fine-tuning the inner knob 44 or the outer knob 45 when adjusting the air supply direction. Rotating the inner knob 44 can initially adjust the general direction of the airflow, while rotating the outer knob 45 can further fine-tune it, guiding the airflow to the desired position. This step-by-step adjustment improves the accuracy of the air supply direction adjustment.

[0061] The spherical groove of the connecting sleeve 46 constrains and supports the outer knob 45, while the second spherical crown groove of the outer knob 45 also provides some restriction and stability to the inner knob 44. During rotation, the multi-layered nested structure mutually restrains each other, reducing unnecessary shaking of the components.

[0062] When the inner knob 44 rotates upwards by 32 degrees, it drives the outer knob 45 and the inner housing 2 to rotate upwards by 32 degrees. Then, when the outer knob 45 rotates 20 degrees around the inner knob 44, it drives the inner housing 2 to rotate 20 degrees. At this point, the inner knob 44 may not rotate. The angular positioning after rotation can be achieved by appropriately setting the friction coefficients between the sphere 43 and the first spherical crown groove 47, the inner knob 44 and the second spherical crown groove, and the outer knob 45 and the spherical groove. Specific values ​​can be set according to actual conditions and will not be elaborated further.

[0063] Third embodiment:

[0064] Based on the second embodiment, combined with Figure 5 The outer wall of the inner knob 44 is provided with a protrusion 48, which abuts against the end of the outer knob 45 through a sealing ring 7.

[0065] The connecting sleeve 46 can initially fill the gap between the ball 43 and the rotating part 41, and the sealing ring 7 can further fill the gap between the outer knob 45 and the inner knob, preventing airflow from leaking out of the rotating assembly 4, so that more airflow can be sent out in the set direction, avoiding the reduction of airflow and deviation of airflow direction caused by air leakage, thereby improving airflow efficiency.

[0066] Fourth embodiment:

[0067] Based on any of the above embodiments, combined with Figure 2The aforementioned limiting component 6 includes a limiting sleeve 62 and a limiting plate 61. The limiting sleeve 62 is connected to the outer shell 1 through the limiting plate 61, and the rotating component 4 is sleeved inside the limiting sleeve 62.

[0068] The inner housing 2 is provided with a second central hole 21, and the rotating part 41 of the limiting sleeve 62 extends out and is inserted into the second central hole 21.

[0069] The outer diameter of the end of the limiting sleeve 62 extending into the outer shell 1 gradually decreases; the inner diameter of the end of the second central hole 21 near the rotating part 41 gradually increases.

[0070] When the rotating part 41 rotates from the central axis of the first central hole 63 to any direction by a preset angle, the inner wall of the second central hole 21 abuts against the outer wall of the limiting sleeve 62.

[0071] The outer diameter of the limiting sleeve 62 gradually decreases and the inner diameter of the second center hole 21 gradually increases. When the rotating part 41 rotates to a preset angle (which can be 32 degrees), the abutment of the side walls of the two sets a clear boundary for the rotation range of the rotating part 41. The limiting sleeve 62 and the limiting plate 61 provide stable support and fixation for the rotating assembly 4.

[0072] Fifth embodiment:

[0073] Based on any of the above embodiments, combined with Figure 1 An operating knob 3 is provided at one end of the inner knob 44 extending out of the second central hole 21. The user can apply force to the inner housing 2 through the operating knob 3 to rotate the inner housing 2.

[0074] Sixth embodiment:

[0075] Based on any of the above embodiments, combined with Figure 2 The inner shell 2 is provided with blades 22.

[0076] Airflow passes through the gap between adjacent blades 22 and blows out. The blades 22 can be tilted inside the inner housing 2.

[0077] Seventh embodiment:

[0078] Based on any of the above embodiments, combined with Figure 6 The rotating assembly 4 is connected to a damper 5 on the side away from the inner housing 2. The airflow is regulated by the damper 5.

[0079] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
