Description

Technical Field

[0001] The present invention relates to the technical field of vehicle air supply, and in particular to an air supply duct, an air supply system and a vehicle. Background Art

[0002] The defrosting and defogging of automobile windshields is a mandatory national regulatory requirement. The defrosting and defogging effect of the windshield directly affects the driver's ability to see the front, and affects the safety and drivability of the vehicle. The automobile defrosting and defogging air supply system is mainly used to direct the air volume to the windshield and side windows. The cross-sectional area of ​​the air supply duct needs to meet the design requirements, otherwise it will cause problems such as abnormal noise, large wind loss and lack of air. However, the air supply ducts of existing vehicles are all set in the dashboard, and the air supply ducts are prone to interfere with the instrument beam. If the cross-sectional area of ​​the air supply duct is to meet the requirements, the instrument beam must avoid the air duct, resulting in the instrument beam adopting a variable cross-section or curved structure, which increases the production cost of the instrument beam and reduces the processing accuracy of the instrument beam.

[0003] Therefore, it is necessary to develop a new air supply duct, air supply system and vehicle to reduce the production cost of the instrument beam and improve the processing accuracy of the instrument beam. Summary of the Invention

[0004] The object of the present invention is to provide an air supply duct, an air supply system and a vehicle, so as to solve the problems of high manufacturing cost and low processing precision of the existing instrument beam.

[0005] In order to solve the above technical problems, the present invention provides an air supply duct, including an instrument beam with a hollow interior and sealed at both ends, and a connecting piece arranged on the outer surface of the instrument beam. The instrument beam is provided with a first connecting hole connecting the inner cavity of the instrument beam and the inner cavity of the connecting piece. The inner cavity of the instrument beam is connected to the air outlet duct, and the inner cavity of the connecting piece is connected to the outlet duct.

[0006] Optionally, the connecting member is a flexible member.

[0007] Optionally, the outlet pipe is sleeved on the outer surface of the connecting piece.

[0008] Optionally, the wall thickness of the connection between the outlet pipe and the connecting piece gradually becomes thinner from one end where the outlet pipe is connected to the connecting piece toward the other end where the outlet pipe is connected to the air outlet piece.

[0009] Optionally, a boss is provided on the outer surface of the connection between the connector and the outlet pipe, and the boss is located inside the outlet pipe.

[0010] Optionally, the connecting member is in the shape of an elongated strip, and the boss extends along the length direction of the connecting member.

[0011] Optionally, a structural member is further included, which is connected to the air outlet of the air outlet duct, and the structural member is arranged on a portion of the outer surface of the instrument beam, and the instrument beam is provided with a second connecting hole connected to the inner cavity of the structural member.

[0012] Optionally, the structural member is a flexible member.

[0013] The present invention also provides an air supply system, comprising a mounting plate connected to an instrument panel and having a mounting hole, an outlet pipe connected to the above-mentioned air supply duct at one end, and an air outlet piece connected to the other end of the outlet pipe, wherein the outlet pipe is a retractable and foldable flexible pipe, and the length of the outlet pipe after extension is greater than the distance between the air supply duct and the mounting hole, the air outlet piece is detachably connected to the mounting plate, and the air outlet piece can extend out of the mounting hole.

[0014] The present invention also provides a vehicle, comprising an instrument panel, an air outlet duct and the above-mentioned air supply system, wherein the air supply system is installed at a structural hole on the instrument panel, and the air supply system is connected to the air outlet duct.

[0015] The air supply duct, air supply system and vehicle provided by the present invention have the following beneficial effects: Since the instrument beam forms an air cavity, the connecting piece also forms an air cavity, the inner cavity of the instrument beam is connected to the inner cavity of the connecting piece, and the air cavity formed by the connecting piece is arranged outside the air cavity formed by the instrument beam. In this way, the cross-sectional area of ​​the air duct can be larger than the cross-sectional area of ​​the air cavity formed by only the connecting piece, and larger than the cross-sectional area of ​​the air cavity formed by only the instrument beam. This can reduce the pressure of the airflow in the air duct, avoid the problems of abnormal noise, large wind loss and the air outlet part failing to discharge air; in addition, using the instrument beam as part of the air duct can avoid the instrument beam from avoiding the air duct in order to ensure the cross-sectional area of ​​the air duct when the air duct passes through the instrument beam, resulting in the instrument beam adopting a variable cross-section or curved structure, increasing the production cost of the instrument beam and reducing the processing accuracy of the instrument beam; in addition, since the instrument beam does not need to avoid the air supply duct, the cross-sectional area of ​​the instrument beam can be made as large as possible, which is convenient for improving the rigidity of the instrument beam.

[0024] refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , Figure 1 is a simplified structural diagram of the air supply system in an embodiment of the present invention, Figure 2 is a partial cross-sectional schematic diagram of the air supply system in an embodiment of the present invention, Figure 3 is another partial cross-sectional schematic diagram of the air supply system in an embodiment of the present invention, Figure 4 FIG. 1 is another partial cross-sectional schematic diagram of the air supply system in an embodiment of the present invention. Figure 5 FIG. 1 is another partial cross-sectional schematic diagram of the air supply system in an embodiment of the present invention. Figure 6 It is a structural schematic diagram of the instrument beam in the air supply duct in an embodiment of the present invention, the air supply duct includes an instrument beam 910 with a hollow interior and sealed at both ends, and a connector 920 arranged on a portion of the outer surface of the instrument beam 910, and a first connecting hole 911 connecting the inner cavity of the instrument beam 910 and the inner cavity of the connector 920 is opened on the instrument beam 910, the inner cavity of the instrument beam 910 is connected to the air outlet duct 200, and the inner cavity of the connector 920 is connected to the outlet duct 300.

[0025] The instrument beam in this application is also called the instrument panel cross beam, which is usually used to support the instrument panel body, air conditioning box, central control screen, steering column and other components. It is usually welded by a main beam and multiple types of brackets. The structure must take into account strength, lightweight and spatial layout; its cross section is usually circular or U-shaped; in lightweight design, its two ends are open, that is, the two end faces of the instrument beam or instrument panel cross beam are not closed; by optimizing the deformation design, it absorbs collision energy, reduces occupant knee injury and forms a knee collision buffer zone; when designing with air conditioning components, in order to avoid interference with air conditioning components, the instrument panel cross beam is designed to be in a bent pipe state. This application uses the instrument panel cross beam as a ventilation duct of one of the air conditioning components and conducts an integrated innovative design. On the one hand, it solves the design defects of the instrument panel cross beam caused by the spatial arrangement of the existing air conditioning components and the instrument panel cross beam. On the other hand, it is conducive to the structural optimization of the instrument panel cross beam, such as but not limited to increasing the spatial cross-sectional area of ​​the instrument panel cross beam, which is conducive to ventilation and air supply while increasing the strength of the instrument beam and improving the collision characteristics.

[0026] Since the instrument beam 910 forms a wind cavity, the connecting piece 920 also forms a wind cavity, the inner cavity of the instrument beam 910 is connected to the inner cavity of the connecting piece 920, and the wind cavity formed by the connecting piece 920 is arranged outside the wind cavity formed by the instrument beam 910. In this way, the cross-sectional area of ​​the air duct can be larger than the cross-sectional area of ​​the wind cavity formed by only the connecting piece 920, and also larger than the cross-sectional area of ​​the wind cavity formed by only the instrument beam 910. In this way, the pressure of the airflow in the air duct can be reduced, and the problems of abnormal noise, large wind loss and the air outlet piece 400 not being able to discharge air can be avoided. In addition, the instrument beam 910 is used as a part of the air duct. Part, it can avoid the problem that when the air duct passes through the instrument beam 910, in order to ensure the cross-sectional area of ​​the air duct, the instrument beam 910 avoids the air duct, resulting in the instrument beam 910 adopting a variable cross-section or curved structure, increasing the production cost of the instrument beam 910 and reducing the processing accuracy of the instrument beam 910, and improving the performance of the beam; in addition, since the instrument beam 910 does not need to avoid the air supply duct, the cross-sectional area of ​​the instrument beam 910 can be made as large as possible, which is convenient for improving the stiffness and strength of the instrument beam 910; in addition, since the instrument beam is part of the air supply duct, this can maximize space utilization.

[0027] In this embodiment, the outlet duct 300 is communicated with the air outlet member 400. The outlet duct 300 can be a rigid duct or a flexible duct.

[0028] In this embodiment, the connector 920 is a rigid member. In other embodiments, the connector 920 is a flexible member. When there is no airflow passing through the connector 920 and the connector 920 is a flexible member, there is no airflow in the connector 920. When there is airflow passing through the connector 920, the connector 920 can act as a buffer to further reduce the pressure of the fluid in the air duct, allowing the airflow to be easily discharged from the air outlet 400.

[0029] Preferably, the outlet pipe 300 is sleeved on the outer surface of the connecting piece 920, so that the outlet pipe 300 is conveniently connected to the connecting piece 920; at the same time, after the air outlet piece 400 is pulled out and installed on the mounting plate 100, the outlet pipe 300 protrudes in a direction away from the inside of the outlet pipe 300, thereby realizing the smooth contraction and folding of the outlet pipe 300.

[0030] refer to Figure 4 and Figure 5 The wall thickness of the outlet duct 300 at the connection with the connector 920 gradually decreases from the first end 310 where the outlet duct 300 connects to the connector 920 toward the second end 320 where the outlet duct 300 connects to the air outlet member 400. This gradually decreases in thickness at the connection between the outlet duct 300 and the connector 920, with the thickness being greatest at the end where the outlet duct 300 connects to the connector 920. This facilitates the outlet duct 300 to bulge away from the interior of the outlet duct 300 after the outlet duct 300 is removed and the air outlet member 400 is installed on the mounting plate 100, allowing the outlet duct 300 to smoothly retract and fold.

[0031] The connecting member 920 and the instrument beam 910 are manufactured by integral injection molding or 3D printing, and can also be welded, riveted or screwed.

[0032] refer to Figure 5 The outer surface of the connection between the connector 920 and the outlet duct 300 is provided with a boss 921. The boss 921 is located inside the outlet duct 300. The boss 921 is provided on the outer surface of the connection between the connector 920 and the outlet duct 300 to guide the outlet duct 300 toward the connector 920. That is, when the outlet duct 300 is moved toward the connector 920, that is, when the removed air outlet member 400 is installed on the mounting plate 100, the connection between the outlet duct 300 and the connector 920 bulges away from the interior of the outlet duct 300, thereby achieving smooth contraction and folding of the outlet duct 300. Furthermore, the boss 921 also acts as a seal, preventing airflow from the outlet duct 300 from leaking from the connection between the outlet duct 300 and the connector 920.

[0033] Preferably, the connecting member 920 is in the shape of a strip, and the boss 921 extends along the length of the connecting member 920. In other embodiments, the bosses 921 may be arranged at intervals, but in this case, the sealing effect of the bosses 921 is not as good as that of the bosses 921 being arranged continuously.

[0034] The air supply device further includes a structural member 930, which is connected to the air outlet of the air outlet duct 200. The structural member 930 is disposed on a portion of the outer surface of the instrument beam 910. The instrument beam 910 defines a second communication hole 912 that communicates with the inner cavity of the structural member 930. Because the structural member 930 forms an air cavity, the instrument beam 910 also forms an air cavity, and the air cavity formed by the structural member 930 and the air cavity formed by the instrument beam 910 communicate with each other, the cross-sectional area of ​​the air duct is increased, ensuring smooth airflow and avoiding problems such as abnormal noise, excessive wind loss, and air failure of the air outlet member 400.

[0035] Preferably, the structural member 930 is a flexible member. In this way, when there is no airflow passing through, there is no air in the structural member 930. When there is airflow passing through, the structural member 930 can play a role in buffering the airflow. In this way, the pressure of the fluid in the air duct can be further reduced, making it easy for the airflow to be discharged from the air outlet member 400.

[0036] The structural member 930 is sleeved on the outer surface of the air outlet duct 200. This facilitates the assembly of the structural member 930.

[0037] The structural member 930 and the instrument beam 910 are manufactured by integral injection molding or 3D printing, and may also be welded, riveted or screwed.

[0038] refer to Figure 4 The instrument beam 910 is provided with air guide ribs 913 that cooperate with the first connecting holes 911 to guide the airflow out of the inner cavity of the instrument beam 910. The air guide ribs 913 facilitate the airflow from the inner cavity of the instrument beam 910 to flow into the connecting piece 920.

[0039] refer to Figure 6The instrument beam of an automobile is a key support for the instrument panel assembly, air ducts, and other system components. Its main functions are to achieve installation and support, occupant protection, and body reinforcement, and are crucial to the overall performance of the vehicle and the safety of the occupants. The common instrument beam layout is constrained by environmental factors such as the instrument panel assembly, air duct, HVAC, front panel, wiring harness, and other system components. This severely limits the layout direction, bracket layout, cross-sectional shape, molding process, and connection process of the instrument panel cross beam. This often results in increased weight, multiple bending and correction, complex cross-sections, complex manufacturing, poor dimensional stability, numerous welded joints, weakened rigidity, affected safety performance, large equipment and mold investment, and mold life. Common air supply ducts usually directly connect the air outlet duct 200 and the air outlet component 400 and are usually rigid components. This requires the instrument beam to avoid the air supply duct. However, the instrument beam in this embodiment adopts the above-mentioned special air supply duct, which avoids the instrument beam adopting a variable cross-section or curved structure to avoid the air supply duct, making the instrument beam basically a straight line with a constant cross-sectional change.

[0040] In this embodiment, the air outlet duct 200 is an air outlet duct of an air conditioner.

[0041] refer to Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 and Figure 19 , Figure 7 Schematic diagram of the structure of the air supply system installed on the instrument panel 600 in an embodiment of the present invention.

Figure 17 A schematic cross-sectional view of a position adjustment assembly of an air supply system according to an embodiment of the invention, Figure 18 A schematic cross-sectional view of the position adjustment assembly of the air supply system according to an embodiment of the invention from another perspective. Figure 19 It is a structural diagram of the defrosting of the air supply system in an embodiment of the present invention. This embodiment also provides an air supply system, including a mounting plate 100 connected to the instrument panel 600 and having a mounting hole, an outlet duct 300 connected to the connector 920 at one end, and an air outlet member 400 connected to the other end of the outlet duct 300, wherein the outlet duct 300 is a retractable and foldable flexible tube, and the length of the outlet duct 300 after extension is greater than the distance between the air supply duct and the mounting hole, and the air outlet member 400 is detachably connected to the mounting plate 100, and the air outlet member 400 can extend out of the mounting hole.

[0042] Since one end of the outlet duct 300 is connected to the air outlet of the air outlet duct 200, and the air outlet piece 400 is connected to the other end of the outlet duct 300, the air flow in the air outlet duct 200 can be discharged from the air outlet piece 400 through the outlet duct 300; since the outlet duct 300 is a retractable and foldable flexible tube, the length of the outlet duct 300 after extension is greater than the distance between the air outlet duct 200 and the mounting hole, and the air outlet piece 400 is detachably connected to the mounting plate 100, and the air outlet piece 400 can be extended out of the mounting hole, so the connection between the air outlet piece 400 and the mounting plate 100 can be untied, and then the air outlet piece 400 can be removed from the mounting hole. The air outlet piece 400 can be pulled out from the hole, so that the position, direction and angle of the air outlet piece 400 can be adjusted in a wide range according to the use requirements; it avoids the problem that after the traditional instrument panel 600 system design is completed, when the defrosting, demisting, blowing and other effects are very different from the CFD simulation or the requirements become higher during the bench verification stage and the prototype vehicle verification stage, the optimization and rectification are very difficult and costly; since the air outlet piece 400 is detachably connected to the mounting plate 100, when the air supply system is used up, the air outlet piece 400 can be returned to the mounting hole and the air outlet piece 400 can be detachably connected to the mounting plate 100 to realize the installation after the air supply system is used up, so the installation and use process is convenient and quick.

[0043] refer to Figure 7 、 Figure 8 and Figure 9The air supply system further includes a connecting assembly. The instrument panel 600 has a structural hole, and the mounting plate 100 is positioned at the structural hole and connected to the instrument panel 600 via the connecting assembly. The connecting assembly allows the mounting plate 100 to move relative to the instrument panel 600 along the X-direction. Once moved to a predetermined position, the mounting plate 100 is fixed relative to the instrument panel 600. This allows the mounting plate 100 to be adjusted relative to the instrument panel 600 along the X-direction. In this embodiment, the X-direction is the direction of vehicle travel.

[0044] refer to Figure 17 and Figure 18 The connecting assembly includes a connecting bracket 510, a slide groove 520 and a slider 530. The two ends of the connecting bracket 510 are respectively detachably fixedly connected to the instrument panel 600. The slide groove 520 has a wavy spring 521 that cooperates with the slider 530. One of the slide groove 520 and the slider 530 is installed on the connecting bracket 510, and the other is installed on the mounting plate 100. Because the chute 520 includes a wavy spring 521 that cooperates with the slider 530, when the mounting plate 100 slides relative to the instrument panel 600 and encounters a peak or trough in the wavy spring 521, the slider 530 can slide smoothly relative to the chute 520. However, when the slider 530 encounters the other peak or trough in the wavy spring 521, it needs to overcome a certain resistance to elastically deform the wavy spring 521 before it can pass through. This improves the sliding feel of the mounting plate 100 relative to the instrument panel 600 and allows the slider 530 to be stuck in the chute 520 after stopping sliding, thus preventing the mounting plate 100 from shaking relative to the instrument panel 600. In other embodiments, the wavy spring 521 may also be a toothed spring.

[0045] In this embodiment, the slide groove 520 is installed on the connecting bracket 510 , and the slider 530 is installed on the mounting plate 100 .

[0046] Furthermore, the surface of the wavy spring 521 is perpendicular to the surface of the mounting plate 100. Thus, when the slider 530 encounters a crest of the wavy spring 521 protruding toward the mounting plate 100, it needs to overcome a certain resistance to elastically deform the wavy spring 521 before it can pass through.

[0047] The slider 530 includes a slider body 531 and a ball 532 that cooperates with the slide groove 520 and is rotatably connected to the slider body 531 .

[0048] In this embodiment, the number of the balls 532 is two. In other embodiments, the number of the balls 532 is three or more.

[0049] In this embodiment, the slider 530 further includes a set of balls 532 rotatably connected to the slider body 531, so that the sliders 530 mounted on both ends of the mounting plate 100 are interchangeable and the sliders 530 can be matched with the slide grooves 520. This improves the versatility of the slider 530.

[0050] The connection assembly also includes a flexible plate 540, which connects the mounting plate 100 and the dashboard 600, mainly to prevent a gap between the mounting plate 100 and the dashboard 600, which is easy to accumulate dust and affect the appearance.

[0051] The air supply system further includes an angle adjustment component 700 for adjusting the outlet angle of the wind discharged from the air outlet member 400. In this way, after the air outlet member 400 is installed on the mounting plate 100, the angle of the airflow discharged from the air outlet member 400 can be adjusted.

[0052] Specifically, refer to Figure 13 、 Figure 14 、 Figure 15 and Figure 16 The angle adjustment assembly 700 includes a dial 710 hinged to the mounting plate 100, a lever 720 hinged to the dial 710, and a guide blade 730 hinged to the mounting plate 100. There are two guide blades 730, and the two guide blades 730 are hinged to the two ends of the lever 720 respectively. The outlet pipe 300 passes through the two guide blades 730. By turning the dial 710, the lever 720 is driven to rotate through the dial 710, thereby driving the guide blades 730 to rotate, and then the guide blades 730 drive the pipe wall of the outlet pipe 300 to deform, thereby adjusting the angle of the airflow discharged from the air outlet member 400.

[0053] In this embodiment, the dial 710 is extended out of the surface of the mounting plate 100 , so that the user can adjust the angle more easily.

[0054] The outlet pipe 300 may be made of a flexible material.

[0055] The outlet duct 300 and the air outlet duct 200 and the air supply member can be manufactured by integral injection molding or 3D printing, or can be welded, riveted or screwed.

[0056] The air outlet member 400 is an air outlet grille.

[0057] Furthermore, the air outlet grille may also be provided with an angle adjustment component.

[0058] The air outlet member 400 is snap-fitted to the mounting hole. In other embodiments, other detachable connection methods may be used, as long as the air outlet member 400 can be repeatedly removed and installed from the mounting plate 100, and this embodiment does not limit this.

[0059] Since the mounting plate 100 of the air supply system is connected to the instrument panel 600 via the flexible plate 540 and the connecting bracket 510, the air supply system can be modularly designed so that the air supply system can be used for different vehicle models, thereby improving the versatility of the air supply system.

[0060] The air supply system further includes a fixing seat 800 , which is used to support and fix the air outlet member 400 after the air outlet member 400 extends out of the mounting plate 100 .

[0061] Specifically, the fixing base 800 is detachably connected to the instrument panel 600, for example, by suction using a nozzle.

[0062] The fixing base 800 can rotate about two mutually perpendicular axes. This improves the reliability of the connection between the fixing base 800 and the air outlet member 400. Specifically, the fixing base 800 includes a first axis seat, a second axis seat rotatably connected to the first axis seat about a first axis, and a third axis seat rotatably connected to the second axis seat about a second axis. The third axis seat is used to detachably secure the air outlet member 400. For example, the air outlet member 400 and the third axis seat can be connected by a clip or magnetic attraction.

[0063] This embodiment further provides a vehicle, comprising an instrument panel 600 , an air outlet duct 200 and the air supply system of the above embodiment, wherein the air supply system is installed at a structural hole on the instrument panel 600 and is connected to the air outlet duct 200 .

[0064] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
