Description

Technical Field

[0001] The present disclosure relates to a roof vent, and more particularly to a roof vent configured to enter the interior of a vehicle to communicate the interior of the vehicle with the outside, circulate or introduce air, and adjust an airflow direction according to a passenger's selection. Background Art

[0002] Generally, a vehicle is a device that moves on land and is a representative means of transportation mainly used for people to travel.

[0003] The vehicle is provided with a passenger compartment (hereinafter referred to as "the interior of the vehicle") in which passengers sit. Generally, the interior of the vehicle is designed to be airtightly sealed from the outside to provide a comfortable riding environment for the passengers.

[0004] Therefore, the interior of the vehicle must be properly ventilated. A commonly used ventilation method is to introduce outside air into the interior of the vehicle when the vehicle is moving.

[0005] However, the amount of air flowing into the vehicle while the vehicle is moving is too small to adequately ventilate the interior of the vehicle, which may have an adverse effect on the health of passengers during long-term driving.

[0006] Furthermore, since the air is not uniformly introduced into the entire interior of the vehicle, only passengers located near the roof vents may receive the ventilated air.

[0007] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure. Therefore, this Background section may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Summary of the invention

[0035] In the figures, reference numerals refer to the same or equivalent parts of the present disclosure throughout the figures of the drawing. DETAILED DESCRIPTION

[0036] The present disclosure is more fully described with reference to the accompanying drawings, in which embodiments of the present disclosure are shown. However, the present disclosure may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Instead, these embodiments are provided so that the present disclosure will be complete and complete and will fully convey the scope of the present disclosure to those of ordinary skill in the art.

[0037] The terms “part” and “component” used in the specification mean a unit for processing at least one function or operation implemented by a hardware component, a software component, or a combination thereof.

[0038] In addition, it will be understood that the terms such as "first" and "second" are only used to distinguish one element from another element. The nature, order or sequence of the corresponding elements are not limited by these terms.

[0039] The term "entry" as used hereinafter refers to the movement of the vent assembly upward into the roof while remaining in a horizontal position within the interior of the vehicle, ie, parallel to the roof.

[0040] The term "inclined" used hereinafter refers to the vent unit entering the roof of the vehicle so that the entry depth of one end of the vent unit and the entry depth of the opposite end of the vent unit are different from each other in the width direction of the vehicle, whereby the plate constituting the vent unit enters the roof to be inclined in the width direction of the vehicle. The present disclosure is not limited to a specific upward tilt direction or upward tilt angle of the vent unit.

[0041] The roof vent according to the present disclosure is configured to distribute air throughout the interior of the vehicle when the vent unit is inset into the roof. The roof vent is configured to distribute air only in a selected area when the vent unit is tilted. However, the present disclosure is not limited to a specific ventilation method.

[0042] Figure 1 is a plan view of a roof of a vehicle including a vent apparatus according to one embodiment of the present disclosure.

[0043] As shown in the drawings, the vehicle roof vent of the present disclosure includes a vehicle roof 10 and a vent assembly 20 .

[0044] At least one vent assembly 20 may be provided in the roof 10, and according to an embodiment of the present disclosure, the vent assemblies 20 may be provided symmetrically with each other in the width direction of the vehicle. The vent assemblies 20 may be located at positions corresponding to the driver's seat and the front passenger seat and at positions corresponding to the respective rear passenger seats.

[0045] In one embodiment of the present disclosure, the vent assembly 20 may be formed to correspond to seats arranged in four rows, and may include vent units corresponding to respective passengers.

[0046] An air conditioning system (not shown) may be provided in the vehicle to heat or cool the interior or exterior air and introduce the heated or cooled air into the interior of the vehicle or circulate it in the interior of the vehicle. This maintains the temperature inside the vehicle at an appropriate level and provides a comfortable riding environment for passengers.

[0047] The air conditioning system may include a roof duct that communicates with the pillar duct and discharges air-conditioned air, and a floor duct that is installed in the floor of the vehicle and discharges air-conditioned air. The vent assembly 20 of the present disclosure disposed in the roof 10 is configured to be fluidly connected to the air conditioning system of the vehicle via the roof duct.

[0048] The roof 10 may include a roof panel (not shown) and a roof lining (not shown). The roof duct may be installed in the roof panel, or may be installed between the roof panel and the roof lining. The roof duct may be used to evenly distribute air for cooling or heating to the interior of the vehicle.

[0049] Furthermore, the air conditioning system and the roof duct may be configured to be fluidly connected to each other via at least one pillar.

[0050] refer to Figure 1 and Figure 2 The vent assembly 20 may include at least one vent unit 200 that is located in the vehicle roof 10 and is configured to enter the vehicle roof or to be tilted after entering the vehicle roof.

[0051] The vent unit 200 of the present disclosure may enter the roof such that it moves upward while maintaining a horizontal state (ie, parallel to the roof 10 of the vehicle), or may be tilted toward a driver seat or a passenger seat located in the interior of the vehicle after entering the roof.

[0052] The vent unit 200 may allow a large amount of outside air (air or wind) to flow into the interior of the vehicle during ventilation. In addition, the vent unit 200 may be opened or closed by a passenger who wishes to circulate air or wishes to change the air inside the vehicle.

[0053] In addition, the vent assembly 20 may include a stabilizing unit 21 disposed between the vent units 200 .

[0054] The smoothing unit 21 may include at least one fine hole formed therein. When the vent unit 200 is not in use, the smoothing unit 21 may generate a weak airflow introduced through a roof duct installed in the roof 10 and may enable indirect blowing of air to the interior of the vehicle.

[0055] Therefore, even when the vent unit 200 is not opened or closed, that is, not entering the roof or not tilted after entering the roof, it is possible to selectively diffuse the air introduced from the air-conditioning system to the passengers through the smoothing unit 21 .

[0056] The stabilizing unit 21 of the present disclosure may be located between two vent units 200 located in the longitudinal direction of the vehicle. Each vent unit 200 may include a plate, and the plate of the vent unit 200 may include fine holes formed therein, similar to the stabilizing unit.

[0057] Since the plate of the vent unit 200 further includes fine holes formed therein to generate a weak airflow, the vent unit 200 may achieve indirect blowing of air without entering the roof or tilting.

[0058] That is, the vent unit 200 may include at least one fine hole formed therein to perform the same function as the stabilizing unit 21 even when the vent unit 200 does not enter the roof or is not tilted. Therefore, even in a state where the vent unit 200 does not enter the roof, the vent unit 200 may perform the same function as the stabilizing unit 21 through the vent assembly 20.

[0059] Figure 2 It shows Figure 1 A view of the vent assembly of a roof vent is shown.

[0060] As shown, the driving unit 300 may drive at least one of the first rack unit 400 or the second rack unit 500 installed in the roof 10 or installed to one side of the vent assembly 20. The driving unit 300 may be implemented as a motor to rotate at least one of the first rack unit 400 or the second rack unit 500.

[0061] The first rack unit 400 may be provided on the back side of the vent unit 200. One end of the first rack unit 400 may be connected to the driving unit 300 to receive a driving force from the driving unit 300. The first rack unit 400 may be operated to cause the vent unit 200 to enter the roof or tilt after entering.

[0062] One end of the second rack unit 500 may be connected to an end of the first rack unit 400 to be interlocked with the first rack unit 400. Specifically, the end of the second rack unit 500 may contact the end of the first rack unit 400 connected to the driving unit 300, whereby the driving force transmitted to the first rack unit 400 may also be simultaneously applied to the second rack unit 500. Therefore, the second rack unit 500 may be operated to cause the vent unit 200 to enter the roof or tilt after entering.

[0063] In other words, the first rack unit 400 and the second rack unit 500 are interlocked with each other, that is, rotated together by the single driving unit 300. To this end, the end of the first rack unit 400 and the end of the second rack unit 500 facing each other may include gear portions that mesh with each other (see Figure 3 ).

[0064] In one embodiment of the present disclosure, either the first rack unit 400 or the second rack unit 500 may be connected to one end of the driving unit 300 so that the driving force of the driving unit 300 is applied to the first rack unit 400 or the second rack unit 500 .

[0065] The first groove 600 is formed in one end portion of the vent unit 200. The first protrusion 410 formed at the opposite end of the first rack unit 400 adjacent to the driving unit is inserted into the first groove 600 so that the opposite end of the first rack unit 400 moves along the first groove 600 in a sliding manner.

[0066] The first groove 600 may be formed in a horizontal direction, ie, parallel to the roof 10 , to guide the sliding movement of the first protrusion 410 .

[0067] The second groove 700 is formed in opposite end portions of the vent unit 200. The second protrusion 510 formed at the opposite end of the second rack unit 500 is inserted into the second groove 700 to slide in the horizontal direction along the second groove 700 when the driving force is applied to the first rack unit 400.

[0068] The second groove 700 may be formed in a horizontal direction, ie, parallel to the roof 10. Therefore, when the vent unit 200 enters the roof, the second protrusion 510 may slide from one inner end of the second groove 700 to an opposite inner end of the second groove 700.

[0069] When the vent unit 200 is tilted, the first protrusion 410 and the second protrusion 510 may move away from each other. The first groove 600 and the second groove 700 may be formed in a longitudinal direction of the vent unit 200 .

[0070] In another embodiment of the present disclosure, the opposite end of the first rack unit 400 may have a circular shape. The circular opposite end of the first rack unit 400 may be engaged with the first groove 600 to move along the first recess 600. The opposite end of the second rack unit 500 may also have a circular shape. The circular opposite end of the second rack unit 500 may be engaged with the second groove 700 to move along the second recess 700.

[0071] In addition, the circular end of the first rack unit 400 and the circular end of the second rack unit 500 may be respectively inserted into the first groove 600 and the second groove 700 in an interference fit manner. In addition, the first rack unit 400 and the second rack unit 500 may be configured to rotate a predetermined distance in the width direction of the vent unit 200 to correspond to the tilting operation of the vent unit 200.

[0072] Furthermore, the first recess 600 and the second recess 700 into which the first rack unit 400 and the second rack unit 500 are respectively inserted may be formed to have an open top surface so that when the vent unit 200 is tilted, the first rack unit 400 and the second rack unit 500 move a predetermined distance in the width direction of the vehicle.

[0073] like Figure 2 and Figure 3 As shown, the vent unit 200 may be provided on the rear surface thereof with at least one connection member 210. The connection member 210 may move along a guide groove 211 formed in the roof 10 to correspond to the connection member 210.

[0074] When the vent unit 200 enters the roof, the connecting member 210 may move along the guide groove 211. In addition, when the vent unit 200 enters the roof, the connecting member 210 may be used to limit the movement of the vent unit 200 to prevent the vent unit 200 from shaking and to maintain and fix the vent unit 200 in a horizontal state.

[0075] The guide groove 211 is used to guide the vertical movement of the connection member 210. The guide groove 211 includes a first guide 211a and a second guide 211b, which are provided at both sides of the connection member 210 in the width direction of the vent unit 200.

[0076] The guide groove 211 further includes a stopper 212 formed at the first guide 211 a to restrict upward movement of one end of the connection member 210 when the connection member 210 moves vertically.

[0077] In other words, the end of the connecting member 210 that moves vertically upward along the first guide 211a contacts and is stopped by the stopper 212 formed at the first guide 211a. The opposite end of the connecting member 210 moves vertically upward continuously along the second guide 211b without a stopper. Therefore, the vent unit 200 that has entered the roof is tilted toward the side surface of the roof.

[0078] In other words, the vent unit 200 that has entered the vehicle roof is inclined in such a manner that one end of the vent unit 200 enters further than the opposite end of the vent unit 200 .

[0079] Figure 3 and Figure 4 2 is a view showing a state in which the vent unit 200 of the vent assembly is introduced into the roof of the vehicle.

[0080] As shown in the drawing, when the vent unit 200 enters the roof, the first rack unit 400 is coupled to the first groove 600. The first protrusion 410 moves along the first groove 600 in the longitudinal direction of the vent unit 200.

[0081] In addition, the second protrusion 510 of the second rack unit 500 moves along the second groove 700 in a direction away from the first protrusion 410 .

[0082] Furthermore, when the first protrusion 410 and the second protrusion 510 move away from each other, the at least one connection member 210 moves in an upward direction of the vehicle along the guide groove 211. The vent unit 200 enters the roof while remaining parallel to the roof.

[0083] In other words, when the vent unit 200 enters the roof, the first protrusion 410 of the first rack unit 300 moves along the first groove 600. The second protrusion 510 of the second rack unit 500 moves along the second groove 700 in a direction away from the first protrusion 410.

[0084] Furthermore, the first protrusion 410 , the second protrusion 510 , and the connection member 210 move in an interlocking manner according to the upward vertical movement of the vent unit 200 .

[0085] like Figure 4 As shown, when the first protrusion 410 and the second protrusion 510 are respectively located at the ends of the first groove 600 and the second groove 700 which are farthest from each other in the longitudinal direction, the vent unit 200 completely enters the vehicle roof.

[0086] Furthermore, when the connection member 210 moves in the vertical direction of the vehicle along the guide groove 211, one end of the connection member 210 is stopped by the stopper 212 formed at the first guide 211a. This enables a tilting operation of the vent unit 200.

[0087] Figure 5 The coupling relationship between the guide groove 211 and the connecting member 210 according to one embodiment of the present disclosure is shown.

[0088] As shown in the figure, when the connecting member 210 moves along the guide groove 211 in the vertical direction of the vehicle, one end of the connecting member 210 facing the first guide 211 a is stopped by the stopper 212 formed at the first guide 211 a.

[0089] On the other hand, the opposite end of the connection member 210 facing the second guide 211b without the stopper moves to the upper end of the guide groove 211. This enables the tilting operation of the vent unit 200. The tilting angle of the vent unit 200 can be set by the tilting degree of the connection member 210.

[0090] In addition, the at least one connection member 210 may include a plurality of connection members 210 which are spaced apart from each other in a longitudinal direction with respect to the driving unit 300. A plurality of guide grooves 211 may be formed to correspond to the connection members 210.

[0091] The stopper 212 may be provided in the guide groove 211 away from the center of the vehicle interior so that the end of the vent unit 200 near the center of the vehicle interior enters the roof further than the opposite end of the vent unit 220. The depth to which the end of the vent unit 200 enters the roof may vary according to the setting.

[0092] Therefore, one end of the vent unit 200 having a larger entry depth receives a large amount of air from the roof duct, and strong wind is discharged through the other end of the vent unit 200 having a smaller entry depth. In other words, the strength of wind discharged through the end of the vent unit 200 located adjacent to the stopper increases.

[0093] In other words, the strength of the discharged wind and the direction in which the wind is introduced into the vehicle interior may vary according to the angle at which the vent unit 200 is inclined.

[0094] In addition, the roof vent may further include a position sensor (not shown) for detecting the position of the passenger and a controller (not shown) for controlling an entry or tilt operation of the vent unit 200 according to the position of the passenger.

[0095] In addition, according to one embodiment of the present disclosure, the controller may receive measured temperature values ​​from an external air temperature sensor (not shown) and an in-vehicle temperature sensor (not shown) of the vehicle. The controller may also perform an inlet or tilt operation of the vent unit 200 according to the received temperature values, and may control the amount of air exhausted through the vent unit 200.

[0096] In addition, according to one embodiment of the present disclosure, the controller may detect the position of the passenger using a position sensor, and may determine whether air conditioning inside the vehicle is necessary using an outside air temperature sensor and an in-vehicle temperature sensor of the vehicle. In other words, the controller may receive a measurement value, and may control the operation of the vent unit 200 based on the received measurement value.

[0097] In addition, the controller may include a lighting unit (not shown), which includes a brightness sensor (not shown) for sensing the brightness inside the vehicle when a passenger rides in the vehicle, and the lighting unit includes a lighting sensor (not shown) for turning on / off the light according to the brightness.

[0098] A position sensor may be installed in the seat to detect the position of the passenger. When the passenger sits on the seat, the controller may determine whether to perform an entry operation or a tilt operation of the vent unit 200 according to the seat position of the passenger.

[0099] In other words, the controller may control the operation of the vent unit 200 in consideration of factors such as the interior temperature of the vehicle, the exterior temperature of the vehicle, and a user request.

[0100] When the vent unit 200 enters the roof, the vent unit 200 can cause air to be uniformly introduced into the interior of the vehicle regardless of the seating position of the passenger according to the user's request. In addition, when the vent unit 200 is tilted after entering the roof, the vent unit 200 can cause a larger amount of air to flow to a selected area compared to other areas according to the seating position of the passenger.

[0101] The controller may control the vent unit 200 to enter the roof to uniformly introduce air into the interior of the vehicle through the vent unit 200, and to tilt the vent unit 200 after entering to cause a larger amount of air to flow to a selected area according to a user's position or a user's request.

[0102] In order to increase the amount of air discharged to achieve a dense flow of air to a selected area, the stopper 212 of the present disclosure is provided on a side surface of the guide groove 211 close to the area where the air densely flows.

[0103] Therefore, the end of the vent unit 200 with a smaller entry depth is arranged close to the area where the air densely flows. The end of the vent unit 200 with a larger entry depth is arranged away from the corresponding area. As a result, the strength of the wind discharged to the area located close to the end of the vent unit 200 with a smaller entry depth may increase.

[0104] In addition, according to one embodiment of the present disclosure, since the controller includes a roof vent and a lighting unit interlocked with a position sensor, the controller can perform control to turn on the lights in the area where the passengers are located and cause the opposite end of the vent unit 200 facing the passengers to further enter the roof.

[0105] Figure 62 is a view showing a roof vent according to another embodiment of the present disclosure. The vent unit 200 is tilted after entering the roof of the vehicle using at least one fixing member disposed to be offset from the central axis in the longitudinal direction of the vent unit 200 .

[0106] The at least one fixing member may include a plurality of fixing members 800 disposed offset from the central axis in the longitudinal direction of the vent unit 200 .

[0107] The fixing member 800 may be offset from the central axis in the longitudinal direction of the vent unit 200, and may be spaced apart from the surface of the roof by a predetermined distance in the height direction of the vehicle. Therefore, the vent unit 200 enters the roof after moving the predetermined distance. The side of the vent unit 200 positioned opposite to the fixing member 800 (i.e., the side of the vent unit 200 without the fixing member) enters the roof further than the opposite side of the vent unit 200.

[0108] The roof vent may further include a first groove 600 and a second groove 700 formed in the back surface of the vent unit 200, and a first rack unit 400 and a second rack unit 500 respectively engaged with the first groove 600 and the second groove 700. Ends of the first rack unit 400 and the second rack unit 500 respectively engaged with the first groove 600 and the second groove 700 may be formed to have a circular cross-section.

[0109] Therefore, when the vent unit 200 is tilted by the fixing member 800 , the rounded ends of the rack units 400 and 500 engaged with the corresponding grooves 600 and 700 may move a predetermined distance in the width direction of the vent unit 200 .

[0110] In other words, the upward movement of the vent unit 200 on one side in the width direction thereof is limited to a predetermined extent by the fixing member 800. The vent unit 200 is allowed to move further upward on the opposite side in the width direction thereof. Therefore, the rounded ends of the rack units 400 and 500 can rotate in the width direction according to the inclination of the vent unit 200 without interfering with the grooves 600 and 700.

[0111] The entry depth of one side of the vent unit 200 is limited by the fixing member. The entry depth of the opposite side of the vent unit 200 is greater than the entry depth of one side of the vent unit 200, whereby the vent unit 200 is inclined in the width direction of the vehicle.

[0112] Figure 7 200 is a view showing a roof vent according to another embodiment of the present disclosure. A rotating gear 1000 is provided as a driving unit, and a rack 1100 is fixed to the back side of the vent unit 200 to convert the rotating force of the driving unit into a vertical driving force.

[0113] As shown in the figure, the rack gear 1100 is fixed to the back side of the vent unit 200 and extends in a direction perpendicular to the roof of the vehicle. The rack gear 1100 is engaged with a rotating gear 1000 configured to be rotated by a driving unit.

[0114] The rotating gear 1000 is used to cause the vent unit 200 to enter the vehicle roof in response to a user request.

[0115] In addition, the roof vent may further include at least one connection member 210 disposed in the longitudinal direction of the vent unit 200 and fixed to the back side of the vent unit 200. The roof vent may further include a guide groove 211 formed in both side surfaces of the vent assembly to receive at least a portion of the connection member 210.

[0116] When the vent unit 200 enters the vehicle roof, the connection member 210 may move simultaneously therewith, and the guide groove 211 may serve to guide the upward movement of the connection member 210 .

[0117] The roof vent may further include a stopper 212 formed at one of the guide grooves 211. Therefore, when the vent unit 200 enters the roof, one side of the vent unit 200 adjacent to the stopper 212 is tilted in the downward direction of the vehicle. As a result, the vent unit 200 is tilted in the width direction of the vehicle.

[0118] According to yet another embodiment of the present disclosure, the roof vent may further include a fixing member 800 that is disposed on at least one end in the longitudinal direction of the vent unit 200 and is disposed to be offset from the central axis in the longitudinal direction of the vent unit 200. Therefore, one side of the vent unit 200 adjacent to the fixing member 800 may be more inclined downward than an opposite side of the vent unit 200.

[0119] As is apparent from the above description, the present disclosure provides a roof vent capable of adjusting the airflow direction so that air is introduced not only into an area corresponding to the installation position of the roof vent but also into an area away from the installation position of the roof vent. This selectively enables air to be uniformly introduced into the interior of a vehicle or the airflow to be concentrated in a desired direction.

[0120] In addition, since the roof vent is configured to be inclined, it is possible to allow air to flow to a selected location or to a selected passenger.

[0121] In addition, since the roof vent is configured to perform an entry or tilt operation in the interior of the vehicle, it is possible to introduce a larger amount of air into the interior of the vehicle compared to a roof vent configured to perform an entry or tilt operation outside the vehicle.

[0122] The above description is an illustration of the present disclosure. In addition, the above disclosure is intended to illustrate and explain the embodiments of the present disclosure. The present disclosure may be used in various other combinations, modifications, and environments. In other words, the present disclosure may be changed or modified within the scope of the concepts of the embodiments disclosed herein, within the equivalent scope of the present disclosure, and / or within the technology and knowledge in the art. The described embodiments illustrate the best techniques for implementing the technical ideas of the present disclosure. Various changes may be made to it according to the needs of the specific application and use of the present disclosure. Therefore, the above description is not intended to limit the present disclosure to these embodiments. In addition, the attached claims should be interpreted as including such other embodiments.
