DETAILED DESCRIPTION

[0041] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0043] refer to Figures 1 to 10 As shown, this embodiment provides an air duct structure, which can be arranged, for example, between the dashboard of the vehicle and the air-conditioning system located behind the dashboard, and can connect the air outlet 2 of the air-conditioning system with the air supply outlet 2 on the dashboard, so that the air from the air outlet 2 of the air-conditioning system can pass through the air duct structure and the air supply outlet 2 in sequence into the vehicle cabin to adjust the temperature of the air in the cabin and enhance the user's driving experience.

[0044] Specifically, refer to Figures 1 to 10 As shown, the air duct structure includes a hollow air duct 1 and an air outlet 2 connected to the air duct 1. The air outlet 2 is provided with a first clamping portion 31 and a first rotating clamping portion 41, and the air duct 1 is provided with a second clamping portion 32 matching the first clamping portion 31 and a second rotating clamping portion 42 matching the first rotating clamping portion 41; the first rotating clamping portion 41 can be clamped with the second rotating clamping portion 42 when the air duct 1 and the air outlet 2 rotate relative to each other in the circumferential direction, and the first clamping portion 31 is clamped with the second clamping portion 32 when the first rotating clamping portion 41 and the second rotating clamping portion 42 are clamped, so as to connect the air outlet 2 to one end of the air duct 1.

[0045] During specific use, the first rotating clamping part 41 on the air outlet 2 and the second rotating clamping part 42 on the air duct 1 are matched together, and the air duct 1 or the air outlet 2 is rotated to make the first rotating clamping part 41 and the second rotating clamping part 42 rotate circumferentially relative to each other until the first rotating clamping part 41 and the second rotating clamping part 42 are clamped and connected. At the same time, the first clamping part 31 and the second clamping part 32 are also clamped together, so that the air outlet 2 can be connected to the end of the air duct 1.

[0046] That is to say, the air outlet 2 can be connected to one end of the air duct 1 through the rotational engagement of the first rotational engagement portion 41 and the second rotational engagement portion 42 and the engagement of the first engaging portion 31 and the second engaging portion 32 .

[0047] When the air outlet 2 and the air duct 1 are connected in place, the inner cavity of the air outlet 2 and the inner cavity of the air duct 1 are communicated to form the inner cavity of the air duct structure for air to pass through.

[0048] Based on this, when connecting the air outlet 2 and the air duct 1 of the air duct structure of this embodiment, no additional fasteners such as screws or additional tools such as screwdrivers are required, which simplifies the connection process between the air outlet 2 and the air duct 1, makes the assembly convenient and reliable, and has a high assembly efficiency.

[0049] In a specific implementation, the air vent 2 and the air duct 1 can be arranged on a dashboard, for example, and the air vent 2 can be connected to an end of the air duct 1 that is away from the air conditioning system.

[0050] The air duct structure provided in this embodiment is provided with a hollow air duct 1 and an air outlet 2 connected with the air duct 1, and a first clamping part 31 and a first rotating clamping part 41 are provided on the air outlet 2, and a second clamping part 32 matching the first clamping part 31 and a second rotating clamping part 42 matching the first rotating clamping part 41 are provided on the air duct 1. The first rotating clamping part 41 can be clamped with the second rotating clamping part 42 when the air duct 1 and the air outlet 2 rotate relative to each other in the circumferential direction, and the first clamping part 31 is clamped with the second clamping part 32 when the first rotating clamping part 41 and the second rotating clamping part 42 are clamped, so as to connect the air outlet 2 to one end of the air duct 1. When it is used specifically, the first rotating clamping part 41 and the second rotating clamping part 42 are first matched, and then one of the air duct 1 and the air outlet 2 is rotated to make the first rotating clamping part 41 and the second rotating clamping part 42 rotate relative to each other in the circumferential direction, so that the first rotating clamping part 41 and the second rotating clamping part 42 can be clamped. When the first rotating engaging portion 41 and the second rotating engaging portion 42 are engaged in place, the first engaging portion 31 and the second engaging portion 32 are also engaged together, so that the air outlet 2 can be connected to one end of the air duct 1. That is to say, the air outlet 2 and the air duct 1 can be connected together by the rotational engagement of the first rotating engaging portion 41 and the second rotating engaging portion 42, and the engagement of the first engaging portion 31 and the second engaging portion 32. Compared with the solution in the prior art that the air duct 1 and the air outlet 2 are connected by screws and a tool such as a screwdriver is required to achieve the connection, the air duct structure of this embodiment only needs to rotate the air duct 1 or the air outlet 2 when connecting, and no additional tools such as a screwdriver are required, which simplifies the connection process and improves the convenience and efficiency of assembly.

[0051] In some embodiments, reference Figure 1 , Figure 4 , Figures 7 to 10 As shown, the first rotating engaging portion 41 includes a locking protrusion, and the second rotating engaging portion 42 includes a locking groove for the locking protrusion to be rotatably engaged. The rotating engagement is achieved through the cooperation of the locking protrusion and the locking groove. The structure is simple, easy to implement, and the connection is convenient and reliable.

[0052] The extending direction of the card slot is not a straight line. For example, the card slot may extend in at least two intersecting directions to form a special-shaped slot, such as an L-shaped card slot.

[0053] In other embodiments, the first rotating engaging portion may be, for example, a locking protrusion provided on the air duct, and the second rotating engaging portion may be, for example, a locking groove provided on the air outlet.

[0054] In some embodiments, reference Figures 7 and 8 As shown in FIG. 1 , the card slot includes a matching section 421 for the card protrusion to enter and a card connection section 422 for card connection with the card protrusion. The matching section 421 is along the axial direction of the air duct 1 (refer to FIG. 1 ). Figure 1The line (1) indicated by the double arrows in the middle extends, the engaging section 422 extends along the circumferential direction of the air duct 1, and is connected to the end of the matching section 421 away from the air outlet 2, forming a substantially L-shaped engaging groove. The matching section 421 is connected to the engaging section 422, so that the engaging protrusion enters the engaging section 422 from the matching section 421 when the air duct 1 and the air outlet 2 rotate relative to each other in the circumferential direction.

[0055] During specific use, the latch is extended into the mating section 421, and the air duct 1 or air outlet 2 is moved along the axial direction of the air duct 1, so that the latch moves to the junction of the mating section 421 and the snap-fit ​​section 422, and then the air duct 1 or air outlet 2 is rotated circumferentially of the air duct 1, and the latch enters the snap-fit ​​section 422 and is snap-fitted and connected with the snap-fit ​​section 422.

[0056] Through the engagement connection between the cam and the engagement section 422, on the one hand, the relative movement of the air duct 1 and the air outlet 2 in the axial direction of the air duct 1 can be restricted. On the other hand, the rotation of the air duct 1 and the air outlet 2 toward one side in the circumferential direction of the air duct 1 can also be restricted. For example, referring to Figure 2 and Figure 7 As shown, when the locking protrusion and the locking section 422 are locked in place, the air duct 1 will not rotate clockwise relative to the air outlet 2.

[0057] When the locking protrusion and the locking section 422 are locked in place, the first connection part and the second connection part are also locked together, so that the air duct 1 and the air outlet 2 can at least be restricted from rotating toward the other side in the circumferential direction of the air duct 1 through the locking of the first connection part and the second connection part. Figure 2 and Figure 7 As shown, when the first connection portion and the second connection portion are engaged, the air duct 1 will not rotate counterclockwise relative to the air outlet 2.

[0058] In some embodiments, reference Figure 1 , Figure 7 and Figure 8 As shown, the arc transition at the junction of the mating section 421 and the snap-fit ​​section 422 makes the inner wall of the snap-fit ​​groove at the contact point between the mating section 421 and the snap-fit ​​section 422 relatively smooth. In this way, when the air duct 1 and the air outlet 2 rotate circumferentially relative to each other, it is convenient for the snap-fitting protrusion to enter the snap-fit ​​section 422 from the mating section 421, thereby facilitating the rotational snap-fit ​​connection between the two, further improving the assembly convenience between the air outlet 2 and the air duct 1.

[0059] In some embodiments, reference Figure 7 and Figure 8 As shown, in the axial direction of the air duct 1, the end of the mating section 421 facing away from the snap-in section 422 is open and is located on the end face of the air duct 1 facing the air outlet 2. That is to say, the end of the snap-in groove on the air duct 1 facing the air outlet 2 is open and is formed on the end face of the air duct 1, which facilitates the snap-in protrusion to enter the mating section 421, thereby further improving the assembly convenience between the air outlet 2 and the air duct 1.

[0060] In some embodiments, reference Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, in the radial direction of the air duct 1, a cover body 5 is provided on the side of the slot facing away from the air outlet 2, and the shape of the cover body 5 matches the shape of the slot, that is, the slot is a blind slot, which can improve the sealing of the air duct structure, has better air tightness and better ventilation performance.

[0061] In a specific implementation, part of the side wall of the air duct 1 protrudes outward along the radial direction of the air duct 1 to form a cover 5, and the side of the cover 5 facing the axis of the air duct 1 is a slot. The cover 5 and the air duct 1 are integrally formed, with good integrity and high structural strength. Of course, the cover 5 can also be bonded or welded to the side of the slot away from the air outlet 2.

[0062] In other embodiments, the slot may be, for example, a through slot opened on the side wall of the air duct.

[0063] Among them, reference Figure 4 As shown, the side of the cover body 5 facing the card slot matches the outer contour of the card protrusion, so that when the card protrusion and the card slot cooperate, the fit is better and the card connection is convenient.

[0064] In some embodiments, reference Figure 1 , Figure 5 , Figure 8 and Fig.10 As shown, the first clamping portion 31 is an insertion protrusion, and the second clamping portion 32 is a slot for the insertion protrusion to pass through. The structure is simple, easy to manufacture, and the connection is convenient and stable.

[0065] In other embodiments, the first clamping portion is a protrusion disposed on the air duct, and the second clamping portion is a slot disposed on the air outlet.

[0066] In some embodiments, reference Figure 5 As shown, the side wall of the insertion protrusion is provided with a guiding slope 6 for guiding the slot when the slot is inserted into the insertion protrusion, and the guiding slope 6 is located on the side of the insertion protrusion facing the slot along the circumference of the air duct 1. And in the direction from the air outlet 2 to the air duct 1, the guiding slope 6 is arranged to be inclined inward.

[0067] When the clamping protrusion is located at the joint of the matching section 421 and the clamping section 422, the air outlet 2 and the air duct 1 are rotated in the direction (reference Figure 1 On the line S with double arrows in the middle, the slot is located at the front side of the plug-in protrusion. When the air outlet 2 or the air duct 1 rotates, so that the plug-in protrusion enters the clamping section 422 and is clamped with the clamping section 422, the slot moves toward the plug-in protrusion and is clamped with the plug-in protrusion.

[0068] In some implementations, reference Figure 1 and Figure 5 As shown, the guide slope is arranged to be inclined inward in the direction from the end of the insertion protrusion away from the air duct 1 to the end of the insertion protrusion close to the air duct 1. That is to say, in the direction from the air outlet 2 to the air duct 1, the size of the insertion protrusion in the circumferential direction of the air outlet 2 gradually decreases, which facilitates the insertion of the slot on the insertion protrusion.

[0069] During the movement of the slot, the guide bevel 6 has a guiding effect on the insertion and snap-fitting between the slot and the insertion protrusion, which facilitates the snap-fitting of the insertion protrusion and the slot, making the plug-in efficiency between the insertion protrusion and the slot higher. Therefore, when the snap-fitting protrusion and the snap-fitting section 422 are snapped, the insertion protrusion and the slot can be quickly snapped together, further improving the convenience of assembly between the air outlet 2 and the air duct 1, and improving the assembly efficiency.

[0070] In some embodiments, reference Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.10 As shown, the air outlet 2 includes a mounting seat 21 and a connecting pipe 22 passing through the mounting seat 21. The first clamping portion 31 is arranged on a surface of the mounting seat 21 facing the air duct 1, and the first rotating clamping portion 41 is arranged on the side wall of the connecting pipe 22 and is located on a side of the mounting seat 21 facing the air duct 1.

[0071] For specific implementation, refer to Figure 1 As shown, the mounting seat 21 is provided with a mounting opening 211, and the connecting pipe 22 is passed through the mounting opening 211. Figure 2 , Figure 4 and Figure 7 As shown, one end of the connecting tube 22 facing away from the air duct 1 abuts against a surface of the mounting seat 21 facing away from the air duct 1 , and one end of the connecting tube 22 facing toward the air duct 1 is exposed on a side of the mounting seat 21 facing toward the air duct 1 .

[0072] Specifically, refer to Fig. 9 and Fig.10 Therefore, an insertion protrusion is provided on the surface of the mounting seat 21 facing the air duct 1, and the insertion protrusion extends along the axial direction of the connecting tube 22. A clamping protrusion is provided on the side wall of the connecting tube 22, and the clamping protrusion extends along the radial direction of the connecting tube 22. When specifically connected, the connecting tube 22 is sleeved and connected to the end of the air duct 1, and the mounting seat 21 abuts against the end surface of the air duct 1.

[0073] In some embodiments, reference Figure 8 As shown, the air duct 1 includes a stop wall 11 and a hollow air duct 12. The stop wall 11 is arranged at the end of the air duct 1 along the circumference of the air duct 1 and is used to abut against the air outlet 2. The second clamping portion 32 is arranged on the stop wall 11, and the second rotating clamping portion 42 is arranged on the side wall of the air duct 12. The structure is simple, easy to manufacture and connect, and easy to assemble.

[0074] Specifically, a slot is provided on the stop wall 11 , and a clamping slot is provided on the side wall of the air duct 12 .

[0075] For specific connection, refer to Figure 2 , Figure 4 and Figure 7 As shown, the air duct 12 is sleeved and connected with the connecting pipe 22, and the mounting seat 21 abuts against the stop wall 11. The slot and the insertion protrusion are snap-fitted along the axial direction of the air duct 1, and the snap-fitting protrusion and the snap-fitting slot are snap-fitted along the radial rotation of the air duct 1, thereby limiting the relative position of the air duct 1 and the air outlet 2 in the circumferential and axial directions of the air duct 1, and the connection is convenient and reliable.

[0076] In a specific implementation, the end of the slot on the air duct 1 facing the air outlet 2 is open, the open part is located on the end surface of the air duct 12, and the other open part is located on the stop wall 11, that is, the opening of the end of the slot facing the air outlet 2 is located at the junction of the air duct 12 and the stop wall 11.

[0077] In some embodiments, reference Figures 1 to 3 , Figures 7 to 10 As shown, there are at least two first clamping parts 31 and at least two first rotating clamping parts 41, and at least two first clamping parts 31 and at least two first rotating clamping parts 41 are spaced and arranged alternately in the circumferential direction of the air outlet 2. That is, referring to Figure 1 As shown, a plurality of first clamping parts 31 are arranged at intervals along the circumference of the air outlet 2, a plurality of first rotating clamping parts 41 are arranged at intervals along the circumference of the air outlet 2, and a first rotating clamping part 41 is arranged between two adjacent first clamping parts 31 in the circumference of the air outlet 2. There are at least two second clamping parts 32, which correspond to the first clamping parts 31 one by one, and there are at least two second rotating clamping parts 42, which correspond to the first rotating clamping parts 41 one by one.

[0078] That is to say, multiple groups of snap-fitting positions extending along the axial direction of the air duct 1 are provided between the air duct 1 and the air outlet 2, and multiple groups of rotating snap-fitting positions extending along the radial direction of the air duct 1 are also provided, so that the connection between the air duct 1 and the air outlet 2 is more firm and reliable.
