Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle accessories, and more particularly to a vent device for a vehicle. Background Art

[0002] Heating, ventilation and air conditioning (HVAC) systems are usually used to control the environment in vehicles, so as to maintain the desired internal environment regardless of the external environment. For vehicles, air conditioning outlets are usually arranged on the dashboard or sub-dashboard of the vehicle to allow air-conditioned air to enter the interior of the vehicle to change the temperature and / or air freshness of the interior of the vehicle. In order to adjust the direction of the airflow, conventional air outlets control the up and down directions and the left and right directions respectively by adjusting the vertical blade group and / or the horizontal blade group or the position and / or degree of inclination of the blade string, and can realize functions such as natural wind outlet to improve the riding comfort of the passengers.

[0003] Although the existing air outlets can meet the airflow adjustment requirements in most cases, according to the user's wishes, the air outlets are preferably set in locations such as vehicle pillars and ceilings, and the airflow direction can be adjusted more flexibly and safely. In this way, due to the limited layout space, the traditional guidance method cannot meet the requirements. In addition, although some existing air outlets use electric control to provide automation of the air outlet method to improve comfort, when adjusting the electric air outlet, it is necessary to, for example, click on the menu of the touch screen, which increases the cumbersomeness of the operation and affects driving safety. Therefore, users still hope to retain the function of manually adjusting the air outlet while providing the electric air outlet function. Utility Model Content

DETAILED DESCRIPTION

[0033] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0034] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0035] Herein, the terms “first”, “second” and the like are not used to limit the order of precedence and the number of components, unless otherwise specified.

[0036] In this document, unless otherwise specifically defined, the terms "installation", "connection", "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0037] It should be understood that the term "vehicle" mentioned in this article includes but is not limited to vehicles, ships, airplanes, etc., where "vehicle" includes fuel vehicles, hybrid vehicles, electric vehicles, hydrogen-powered vehicles, etc., and can be various types of vehicles, and is not limited to the illustrations.

[0038] Combination Figure 1A and Figure 1BAs shown, the vehicle V includes an interior with an instrument panel IP, and vent devices A are usually arranged in the center and on both sides of the instrument panel IP. According to different user needs, it is desired to apply the vent device A to a position such as a pillar or a ceiling. It should be understood that the vent device A can also be set at any other position in the vehicle, such as a sub-instrument panel, a door trim, an armrest, etc.

[0039] It is known that the common vent device in the current vehicle is to set one or more adjustable blades at the air outlet to provide up and down, left and right wind direction adjustment and airflow cutoff functions. In order to improve the comfort of use in the car, users have put forward more functional requirements, such as airflow gathering and dispersion, natural wind and other air outlet functions, which puts higher requirements on the vent control mechanism, because providing such a device for influencing the airflow may require a large number of parts and structural space, resulting in high costs. Especially for space-constrained locations such as pillars or ceilings, existing vent devices cannot achieve multi-functional air outlet requirements with fewer parts in a compact structural space.

[0040] According to the concept of the present disclosure, there is provided a vent device with an air guide block, the vent device comprising a shell defining an air inlet and an air outlet, and an air guide blade group and an air guide block accommodated in the shell, wherein the air guide block is arranged adjacent to the air outlet and is configured to extend along a first direction and be pivotable about the first direction relative to the shell to adjust the direction of the airflow discharged through the air guide blade group.

[0041] By arranging an air guide block at the air outlet, and the air guide block can pivot relative to the housing, the vent device of the present disclosure can adjust the airflow direction of the air outlet with a compact layout, and is particularly suitable for locations with limited space, such as pillars or ceilings inside a vehicle. Furthermore, by controlling the pivoting movement of the air guide block, such as manual adjustment or electric adjustment, the vent device of the present disclosure can also improve the user's comfort while providing a convenient blind operation possibility, simplifying the operation and improving driving safety.

[0042] Figure 2A A vent device A1 according to a first embodiment of the present disclosure is shown. As an example, the vent device is described in a horizontal arrangement herein, and thus the directions indicated as "vertical" and "horizontal" below are consistent with the vertical and horizontal directions when the vehicle is parked on a flat ground. Figure 2A As shown in , the first direction is indicated by a mark D1, that is, the left-right horizontal direction in the figure, and the second direction is indicated by a mark D2, that is, the up-down vertical direction in the figure and is substantially perpendicular to the first direction D1.

[0043] It should be understood that the above directions are defined for ease of description only. When the vent device is applied to different locations in the vehicle (e.g., a vehicle pillar), the above directions may also change accordingly, for example, the first direction may be a vertical direction. In addition, when the vent device is installed at an angle relative to the horizontal direction, the first direction and the second direction may not be horizontal or vertical.

[0044] In this embodiment, the combination FIG. 2A to FIG. 2C As shown, the vent device A1 includes a housing 100 defining an internal volume or air flow passage, and the housing 100 may include an upper housing 110 and a lower housing 120 attached to each other, and has an air inlet 130 located on one side and an air outlet 140 located on the other opposite side. The air inlet 130 is generally connected to an air flow duct such as an air ventilation system, an air conditioning system, an air heating system, etc., and the air outlet 140 is used to discharge air to the interior of the vehicle. It should be understood that the housing 100 having a hollow structure may have any appropriate cross-sectional shape depending on the environment in which it is applied, and the illustration is only an example.

[0045] In the illustrated embodiment, the wind guide blade group 200 is constructed as a blade string having a rotating shaft 210, and the rotating shaft 210 is arranged along the first direction D1. The wind guide blade group 200 in the form of a blade string can provide a variety of air outlet modes while saving the number of motors, such as natural wind outlet, concentrated blowing, parallel air outlet, and feather-separated air outlet to avoid people, thereby improving the riding comfort of users or passengers. Moreover, compared with conventional blade groups, such as horizontal blade groups usually arranged near the air outlet and vertical blade groups arranged near the air inlet, the blade string only needs to occupy a smaller space in the shell to achieve multi-functional air outlet, which is particularly suitable for compact structural design.

[0046] Advantageously, the air guide block 310 disposed adjacent to the air outlet 140 is configured to pivot coaxially with the air guide blade set 200. In other words, the pivot axis of the air guide block 310 is coaxial with the rotation axis 210 of the blade string, which further enables the vent device to have a compact structure.

[0047] Specifically, combined Figures 2A to 4B As shown, the wind guide block 310 is provided with pivot arms 320 at both ends of the extension direction, and the pivot arms 320 are pivotally connected to the pivot parts 150 at both ends of the housing 100. In the illustrated embodiment, the upper housing 110 of the housing 100 may be provided with an upper semi-axial hole 111, and the lower housing 120 may be provided with a corresponding lower semi-axial hole 121 so as to be engaged with the upper semi-axial hole 111 to form a pivot part 150 in the form of an axial hole, and the rotating shaft 210 of the blade string may extend through the pivot part 150 and be connected to the drive motor. Accordingly, the pivot arm 320 may be provided with a rotating arm hole 321 to be sleeved on the pivot part 150, so that the wind guide block 310 can pivot relative to the housing 100.

[0048] In some embodiments, a damping member may be provided between the pivot arm 320 and the housing 100. For example, a damping member 330 may be provided between the pivot arm 320 and the pivot portion 150. Figure 3B As shown, a damping groove 322 for accommodating a damping member 330 is provided on the pivot arm 320 adjacent to the pivot hole 321. When the pivot arm 320 is sleeved on the pivot portion 150, the damping member 330 can rub against the surface of the pivot portion 150, thereby providing a holding force for the air guide block 310 to stabilize the air guide block 310 at a desired position. The damping member can also be a spring, a marble, a spring, etc.

[0049] It should be understood that although the pivot arm 320 of the air guide block 310 in the illustrated embodiment is configured to have a pivot hole 321, the pivot portion 150 of the housing 100 can be sleeved in the pivot hole 321 (that is, the pivot portion can be regarded as an axis), the pivot arm can also be configured in the form of an axis and sleeved in the pivot portion (that is, the pivot portion can be regarded as an axis hole), for example, when the air guide blade group adopts a conventional blade form, the blade group does not need to pass through the axis of the housing. Therefore, the form of the pivot arm of the air guide block and the pivot portion of the housing shown in the figure is not a limitation and can be adjusted accordingly according to actual needs.

[0050] Advantageously, the air guide block 310 has a guide surface 311 forming an outer contour, such as Figure 4B As shown, the shape of the guide surface 311 is adapted to the contour of the inner surface of the adjacent housing (e.g., the inner surface 112 of the upper housing 110). In this way, the guide surface 311 of the air guide block 310 and the inner surface of the housing form a guide air passage, so that the pivoting of the air guide block 310 relative to the housing can adjust the Figure 4B The direction of the airflow at the air outlet 140 is adjusted by adjusting the ratio of the upper and lower guide air ducts shown. Moreover, as shown in the figure, the structural design and movement mode of the air guide block 310 effectively realize a substantial reduction in the structural dimensions of the vent device in the direction of the air inlet 130 and the air outlet 140. Compared with the existing design in which an air guide structure is provided at the air inlet or an air guide structure is provided at the air outlet (usually translated along the first direction D1 or the second direction D2), the vent device of the present disclosure has a more compact structure, especially the air guide block 310 is configured to pivot coaxially with the rotating shaft 210 of the air guide blade group 200, further making the vent device have a shorter dimension L as shown in the figure, and can be suitable for applications with limited layout space.

[0051] The following combination FIG. 5A to FIG. 5C The specific operation process of the vent device A1 and the wind direction or airflow adjustment function achieved are described.

[0052] Figure 5AThe state of the air guide block 310 being in the first extreme position is shown. At this time, the upward guide surface of the air guide block 310 abuts against the inner surface of the upper shell 110 to close the guide air passage, and the downward guide surface of the air guide block 310 forms an upward guide air passage with the inner surface of the lower shell 120. Under the common guidance of the air guide blade group 200, the air guide block 310 and the lower shell 120, the airflow is guided upward as shown by the arrow.

[0053] Figure 5B The figure shows the state where the air guide block 310 is in the middle position. At this time, the upward guide surface of the air guide block 310 forms a guide air passage with the inner surface of the upper shell 110, and the downward guide surface of the air guide block 310 forms a guide air passage with the inner surface of the lower shell 120. The proportions of the two guide air passages are roughly the same. The upper and lower air flows converge at the air outlet 140 and are guided forward (to the right in the figure) as shown by the arrow.

[0054] Figure 5C The figure shows the state where the air guide block 310 is in the second extreme position. At this time, the downward guide surface of the air guide block 310 abuts against the inner surface of the lower shell 120 to close the guide air passage, and the upward guide surface of the air guide block 310 forms a downward guide air passage with the inner surface of the upper shell 110. Under the common guidance of the air guide blade group 200, the air guide block 310 and the upper shell 110, the airflow is guided downward as shown by the arrow.

[0055] It can be seen that the vent device of the present disclosure provides an effective air guide effect in a compact space, has a simple appearance, a simple and reliable structure, and is low in cost. In addition, in some embodiments, either the air guide block or the air guide blade set may be configured to have an outer surface that matches the contour of the other of the air guide block and the air guide blade set to accommodate the pivoting trajectory of the air guide block. For example, FIG. 5A to FIG. 5C As shown, for the wind guide blade group 200 in the form of a blade string, the wind guide block 310 may have an outer surface 313 that is adapted to the contour of the outer surface 220 of the blade string, thereby ensuring that the wind guide block 310 can smoothly implement the pivoting movement while further contributing to the compact structural design of the vent device.

[0056] Depending on different needs, the pivoting movement of the air guide block 310 can be controlled by a motor to provide automatic operation, or manually controlled to simplify operation. When the manual control mode is adopted, the user can enjoy the comfort of electric air outlet, and the convenient blind operation possibility is provided through the traditional manual operation, thereby improving driving safety.

[0057] As a form of manual control, Figure 2AThe vent device A1 shown may also include a dial button 340, which may be attached to the air guide block 310 and extend out of the housing 100, wherein the dial button 340 may be configured to be movable along the second direction D2, so that the displacement of the dial button 340 in the second direction D2 drives the air guide block 310 to pivot relative to the housing 100. For example, the dial button 340 may form an arc displacement in the second direction D2 (i.e., swing around the first direction D1) or a linear displacement in the second direction D2 (i.e., translate up and down along the second direction D2) or any other possible displacement trajectory. In the illustrated embodiment, the dial button 340 may be formed as one piece with the air guide block 310.

[0058] The above-mentioned air guide block is also applicable to the traditional air guide blade group. FIG. 6A to FIG. 6C Three conventional forms of wind guide blade groups are shown as examples. Figure 2A and Fig. 6A As shown, in some embodiments, the wind guide blade group 400A is constructed to include a plurality of blades arranged at least along the first direction D1 and pivoting around the second direction D2, that is, a traditional form of vertical blade group, which can achieve the direction adjustment of the airflow along the first direction D1 (or horizontal direction). Similarly, the wind guide block 310 can be pivotally connected to the pivot portion of the shell through a pivot arm, except that, in this case, the pivot axis of the wind guide block 310 is not coaxial with the axis on which the blades are arranged, but is located within the projection range of the plane formed by the first direction D1 and the second direction D2. Due to the design of the wind guide block 310, the traditional horizontal blade group arranged near the air outlet can be removed, and the wind direction can be adjusted along the second direction D2 (or vertical direction) through the wind guide block, so that a compact layout space can be obtained, which is suitable for applications with limited layout space. Similarly, in this embodiment, the air guide block 310 may have an outer surface 313 that is adapted to the contour of the outer surface 410A of the blades of the air guide blade group 400A, or the blades of the air guide blade group 400A may have an outer surface 410A that is adapted to the contour of the outer surface 313 of the air guide block 310, for example, the figure shows a convex outer surface 410A to accommodate the pivot trajectory of the air guide block 310.

[0059] Figure 6B In the illustrated embodiment, the blades of the wind guide blade set 400B may be conventional blades with rectangular cross sections, and another form of wind guide block 350 may be used, wherein the wind guide block 350 may be constructed as a hollow structure in which the dial button 360 is embedded. In this embodiment, the pivot axis of the wind guide block 350 pivoting around the first direction D1 may be configured to be arranged in sequence with the blades in the third direction D3, and combined with the wind guide block 350, the wind guide block 350 may be configured to be arranged in sequence with the blades in the third direction D3, and ... Figure 2A As shown, the third direction D3 is perpendicular to the first direction D1 and the second direction D2 respectively.

[0060] Figure 6CThe illustrated embodiment specifically shows the structure of the air guide block 350, and shows another form of the air guide blade group 400C, wherein the air guide blade group 400C is similarly constructed such that the blades may have an outer surface adapted to the outer surface contour of the air guide block 350, for example, the outer surface 410C having an inner concave is shown, or the air guide block 350 may have an outer surface adapted to the outer surface contour of the blades of the air guide blade group 400C to adapt to the pivot trajectory of the air guide block. In this embodiment, the air guide block 350 may be constructed to include an air guide block main board 351 and an air guide block decorative board 352, both of which are attached to form a hollow structure and a dial button 360 may be embedded therein. The dial button 360 may include a dial button block 361 extending out of the housing, and the dial button block 361 may be attached to the air guide block 350 by being attached to a dial button bracket 362 disposed in the hollow structure of the air guide block 350. The dial button 360 is configured as a toggle switch, and is provided with a first limit damper 363 for limiting the movement range of the dial button block 361 in the first direction D1, and a second limit damper 364 for limiting the movement range of the dial button block 361 around the first direction D1 or in the second direction D2. In addition, the dial button 360 may also be provided with a marble 365 for providing a toggle feel.

[0061] FIG. 6D to FIG. 6I The vent device of another embodiment of the present disclosure is shown as an example, which is installed on the vehicle ceiling C. The main structure of the vent device is similar to Figure 4B The vent devices shown are generally similar, so the same or similar structures will not be described in detail. Fig.6D In the vent device shown, the air guide block 370 also has a guide surface that is adapted to the inner surface contour of the adjacent shell. In addition, when the guide surface of the air guide block 370 is adjacent to or abuts the inner surface of the adjacent shell, the outer contour of the air guide block is adapted to the outer contour of the peripheral components of the vent device at the installation position to form a basically coherent curved surface, so that the airflow can meet the Coanda effect at the air outlet. The so-called "Coanda effect" refers to the tendency of a fluid (water flow or airflow) to deviate from the original flow direction and flow along the surface of a protruding object. In this way, due to the Coanda effect, the airflow will diffuse outward along the surface of the outer contour of the peripheral components, which can avoid the discomfort caused by direct airflow.

[0062] Specifically, Fig.6D The state of the air guide block 370 is shown to be in the first extreme position, at which time the outer contour of the air guide block 370 is adapted to the outer contour of the surrounding component of the vent device at the installation position (ie, the vehicle roof C) to form a substantially continuous curved surface. Fig. 6E Shows Fig.6DThe outlet direction of the airflow inside the vehicle when the vent device is in the state, that is, the airflow diffuses along the surface of the outer contour of the vehicle roof C in the direction of the arrow, and then diffuses along the surface of the window glass G, thereby being able to isolate the cold / heat radiation of the windows and / or ceiling through the air-conditioning wind, adjust the local climate inside the vehicle, and avoid the airflow directly blowing on the occupants P inside the vehicle to cause human discomfort, thereby achieving an adjustable guide range of nearly 180°, which is particularly suitable for occasions where air outlets are set on the vehicle roof. Fig. 6F and Fig.6D Similarly, the state where the air guide block 370 is in the middle position is shown. Figure 6G Shows Fig. 6F The air outlet direction of the airflow inside the vehicle when the vent device is in the state, at this time the airflow can be adjusted to the required air outlet direction according to actual needs. Figure 6H and Fig.6D Similarly, the state where the air guide block 370 is in the second extreme position is shown. Fig.6I Shows Figure 6H The airflow direction in the vehicle interior when the vent device is in the state. Similarly, in this case, the airflow diffuses along the surface of the outer contour of the vehicle ceiling C in the direction of the arrow, which can isolate the cold / heat radiation of the vehicle ceiling C, adjust the local climate inside the vehicle, and prevent the airflow from blowing directly on the occupant P and causing human discomfort. It should be understood that although the vent device is shown installed on the vehicle ceiling, based on this concept, the vent device can also be installed at other locations inside the vehicle, such as but not limited to the dashboard, sub-dashboard, door trim, armrest, pillar, etc.

[0063] 7A to 10B Another embodiment of the vent device A2 is shown. Similarly, the vent device A2 includes a housing 100 having an upper housing 110 and a lower housing 120 attached to each other, and an air guide blade group 200 in the form of a blade string, and the air guide block 510 is provided with a pivot arm 520 to pivotally connect to the pivot portion of the housing 100, so as to achieve pivoting around the first direction D1 relative to the housing 100. In addition, a damping member 530 may be provided between the pivot arm 520 and the pivot portion. The difference from the vent device A1 of the above embodiment is that, in this embodiment, the dial button 540 may be configured to be movable along the first direction D1, and the air guide blade group 200 changes the direction of the airflow or changes the air outlet mode in response to the movement of the dial button to achieve wind direction adjustment of different functional modes. In this way, while the button 540 swings around the first direction D1 to realize the pivoting of the air guide block 510 around the shell, the wind direction of the air guide blade group can also be additionally controlled by moving the button 540 along the first direction D1, further optimizing the air outlet effect of the vent device.

[0064] Specifically, combined 7A to 8CThe dial button 540 may include a dial button block 541 extending out of the housing 100 and a lever 543 attached to the dial button block 541, wherein the lever 543 is attached to a displacement sensor 546 (e.g., a linear displacement sensor) to sense the displacement of the dial button block 541 (e.g., a linear displacement along the first direction D1). The vent device further includes a control unit (not shown), which controls the air guide blade group 200 to change the direction of the airflow in response to the displacement signal sensed by the displacement sensor 546. In the illustrated embodiment, three functional modes are exemplarily shown, and three corresponding functional identifiers 550 may be provided on the air guide block 510, so that the user can move the dial button 540 to the corresponding functional identifier 550 according to different needs to achieve the desired air outlet function.

[0065] In the illustrated embodiment, the air guide block 510 may be configured as a hollow structure having a cavity 547, and the displacement sensor 546 is disposed in the cavity 547, and the cavity 547 may be closed by a cover 545. In addition, the air guide block 510 is provided with a button slot 511 through which the lever 543 passes and can move along the first direction D1. In some embodiments, the button block 541 may be attached to the lever 543 via a button bracket 542. Figure 7C , Figure 8B and Figure 8C As shown, the dial button bracket 542 is provided with a lever groove 544 for the lever 543 to be embedded, and the dial button block 541 can also be adapted to the shape of the dial button bracket 542 and be nested and connected. In this way, the movement of the dial button block 541 along the first direction D1 causes the dial button bracket 542 and the lever 543 to move together, and then a corresponding displacement signal is generated through the displacement sensor 546, and the control unit can identify the displacement signal to determine the different positions of the dial button block 541 movement, so as to control the wind guide blade group 200 according to the calibrated preset program to achieve different air outlet functions. It should be understood that, depending on different needs, the dial button 540 can also be changed to, for example, a button switch, a key switch or a touch switch, and is not limited to being able to move along the first direction D1. Depending on different needs, the displacement sensor can also be any other suitable form, such as an angle displacement sensor, to sense the angle displacement of the dial button block, such as around the first direction D1 or the second direction D2 or the third direction D3.

[0066] 9A to 10B The specific operation process of the dial button 540 of the vent device A2 and the wind direction or airflow adjustment function achieved are exemplified.

[0067] Fig.9A and Fig. 9BThe state when the dial button 540 moves to the first position along the first direction D1 is shown, that is, the dial button 540 is moved to the leftmost position. The control unit recognizes the displacement signal and controls the motor to drive the wind guide blade group 200 in the form of a blade string to convert to the natural wind state based on the function identifier 550 corresponding to this position. At this time, the air outlet discharges air in the natural wind state, which can provide turbulent flow in a large range and provide a more uniform cabin temperature experience.

[0068] Fig. 10A and Fig. 10B The state when the dial button 540 moves to the second position along the first direction D1 is shown, that is, the dial button 540 is moved to the rightmost position. The control unit recognizes the displacement signal and controls the motor to drive the wind guide blade group 200 in the form of a blade string to a parallel arrangement state based on the function identifier 550 corresponding to this position. At this time, the air outlet blows out air in a parallel wind state, and the air outlet blows out a more concentrated airflow, which can deliver the airflow to a more accurate local target point (blowing towards people or avoiding people).

[0069] Regardless of the implementation method, the vent device disclosed in the present invention realizes the adjustment of wind direction or airflow through the air guide block in a relatively small space. The vent device has a compact structure and high air guide efficiency, and is particularly suitable for applications with limited layout space. Through different control methods for the pivoting movement of the air guide block, automatic operation and manual operation can be provided according to different needs, wherein the manual operation in the form of a dial button simplifies the tedious operation and improves driving safety. Through further design of the dial button, the pivoting movement of the air guide block and the adjustment function of the air guide blade group can be realized independently or in combination, so as to allow the user to adjust and guide the airflow according to his wishes, thereby improving the user experience.
