Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0142842, filed on October 24, 2023, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The utility model relates to a ventilation module, and more particularly to a ventilation module which can realize a hidden design and cool a tray when not in use. Background Art

[0004] A plurality of ventilators are provided in a cockpit module for cooling, heating and ventilation of the vehicle interior. Typically, a ventilator arranged at the front of the vehicle consists of two central parts and two side parts.

[0005] As the types and functions of vehicles become more diverse, purpose-built vehicles (PBVs) are also being developed. PBVs are vehicles used to achieve specific purposes and may include PBVs dedicated to last-mile transportation and delivery, PBVs for transporting semiconductors, and the like.

[0006] For PBV, autonomous driving can be adopted, and the structure of the vehicle is also different from that of existing vehicles because there may be no passengers or only one driver. Therefore, it is necessary to develop a cockpit for one driver, but it is very likely that instead of using four ventilators in the related art, only two ventilators in the center and one ventilator in the side (driver's seat) will be applied. In this case, air conditioning inside the vehicle may be difficult, and a separate ventilator may be required. In view of the vehicle design and characteristics of PBV, a ventilator that can realize a hidden design and have multiple functions is being studied. Utility Model Content

[0038] Hereinafter, one embodiment of a ventilation module according to the present invention will be described in detail with reference to the accompanying drawings, and the same or corresponding components will be assigned the same reference numerals and overlapping descriptions thereof will be omitted.

[0039] Vehicles that are an improved level compared to existing vehicles, such as autonomous driving vehicles, electric vehicles, etc., are being developed. In addition, special-purpose vehicles have been developed in recent years in which the interior and exterior of the vehicle are modified to support functions suitable for the purpose of the vehicle. Special-purpose vehicles are vehicles whose purpose is not to simply transport passengers, but to provide vehicles suitable for achieving the purpose desired by the user, such as transporting goods or camping by configuring the vehicle according to the purpose.

[0040] For a special vehicle, generally, the seat arrangement inside the vehicle is different from that of an existing vehicle, and the cockpit module 1 formed in front of the driver's seat can also be formed as a simplified mode for a single driver's seat. However, when the existing air conditioning device is applied to the simplified cockpit module 1, air conditioning inside the vehicle may be difficult.

[0041] Existing air conditioning systems achieve air conditioning inside the vehicle by utilizing a total of four ventilators, two of which are located in the center of the vehicle and two of which are located on the sides, but for a simplified cockpit module 1, two ventilators located in the center and one ventilator located on the driver's side may be used, making it difficult to control the temperature of the air inside the vehicle.

[0042] In order to solve the above problems, a ventilation module 100 is needed, which is installed on one side of the cockpit module 1 to adjust the air inside the vehicle and has a separate function. The utility model provides a ventilation module 100, which can realize a hidden design by connecting the housing 10 of the cockpit module 1 and the ventilation part 20 inserted into the housing 10, and simultaneously adjusts the air inside the vehicle and realizes a refrigeration function by cooling the inside of the housing 10.

[0043] Figure 1 2 is a view showing a cockpit to which a ventilation module according to an embodiment of the present invention is applied.

[0044] refer to Figure 1 The ventilation module 100 can be connected to the upper side of the cockpit module 1 of the vehicle, and can discharge air to the interior of the vehicle so that cooling and heating are possible. The housing 10 and the housing door 12 can be formed in front of the ventilation part 20 so that the occupant can store drinks, food or separate luggage inside the housing 10.

[0045] There is no limitation on the position where the ventilation module 100 is installed, and the position may be changed according to the position of ventilation applied to the vehicle to facilitate adjustment of the air temperature inside the vehicle.

[0046] Figure 2 is a perspective view of a ventilation module according to an embodiment of the present invention.

[0047] refer to Figure 2 According to an embodiment of the present invention, a ventilation module 100 may include: a shell 10 having an open upper side and a connecting hole 14, through which an air flow is formed at the rear side; a shell door 12, which is rotatably connected to the shell 10 to open or close the open upper side of the shell 10; and a ventilation part 20, which is rotatably arranged inside the shell 10 by being inserted through the connecting hole 14 and discharges air.

[0048] The ventilation portion 20 may be disposed at the rear side of the housing door 12 , and a plurality of ventilation portions 20 may be formed. Figure 2 It is shown that two ventilation parts 20 are formed at the rear side of the housing door 12. The housing door 12 can be opened and closed in a rotational manner, and a rotation axis can be formed at the rear boundary of the housing door 12 to facilitate opening and closing the housing door 12.

[0049] Similarly, the rotation axis of the ventilation portion 20 may also be formed at the rear side of the ventilation portion 20 to facilitate the rotation of the ventilation portion 20. The rotation axis of the ventilation portion 20 and the rotation axis of the housing door 12 may be formed to extend in the width direction of the housing 10.

[0050] The housing 10 may be connected to the upper side of the cockpit module 1 to facilitate access or visit by the occupant, and the occupant may open the housing door 12 and store luggage inside the housing 10. In addition, since the ventilation portion 20 may discharge air into the housing 10, cooling inside the housing 10 is also possible. Therefore, the occupant may store beverages, food, etc. that require cooling inside the housing 10.

[0051] The plurality of ventilation portions 20 may be individually controlled, and thus at least some of the ventilation portions may be arranged to discharge air into the housing 10 , and the remaining ventilation portions may rotate to discharge air into the vehicle.

[0052] A handle may be formed on one end of the ventilation portion 20 and the housing door 12 so that the user can rotate the ventilation portion and the housing door by pulling the handle. The user can open or close the housing door 12 by holding the handle and lifting the handle upward to adjust the ventilation portion 20 so that it is inserted into the housing 10, or expose it to the open upper side of the housing 10 so that air is discharged into the vehicle.

[0053] Alternatively, the ventilation part 20 and the housing door 12 can be rotated electronically. A motor can be mounted on the rotation axis of the ventilation part 20 and the rotation axis of the housing door 12, and when the user operates the button, the controller can drive the motor to rotate the ventilation part 20 and the housing door 12 by a preset value.

[0054] Hereinafter, the position in which the ventilation portion 20 is inserted into the shell 10 in response to being rotated downward at the maximum angle is referred to as the first position, and the position in which the ventilation portion 20 is exposed to the outside of the shell 10 in response to being rotated upward at the maximum angle so that air is discharged into the vehicle is referred to as the second position.

[0055] Figure 3 is a cross-sectional view of a ventilation module arranged in a first position according to an embodiment of the present invention, and Figure 4 is a cross-sectional view of a ventilation module arranged in a second position according to an embodiment of the utility model.

[0056] refer to Figure 3 and Figure 4 According to an embodiment of the present invention, the ventilation portion 20 of the ventilation module 100 may include: a cover 22, which is arranged in a horizontal direction when the ventilation portion is arranged in a first position; an inflow portion 24, which is formed at one end of the cover 22 in a direction intersecting with a surface direction of the cover 22, and air flows through the inflow portion 24; and a discharge portion 26, which connects the cover 22 and the inflow portion 24, and discharges air through the discharge portion 26.

[0057] As shown in the figure, the cross section of the ventilation part 20 including the cover 22, the inflow part 24 and the discharge part 26 may be triangular, and the cover 22 and the inflow part 24 may be formed to intersect vertically. Even if the cover 22 and the inflow part 24 are not vertical, the arrangement of the cover 22 and the inflow part 24 is not important, and any arrangement may be used as long as the ventilation part 20 can be fully inserted into the housing 10 or fully exposed depending on the rotation angle of the ventilation part 20.

[0058] The ventilation portion 20 may have three surfaces formed of the cover 22, the inflow portion 24, and the discharge portion 26, and both side surfaces thereof may also be formed to be closed so that air is discharged only through the discharge portion 26. The discharge portion 26 may be opened with a hole formed so that air can be discharged.

[0059] A communication hole 14 may be formed at the rear side of the housing 10. The ventilation portion 20 may be arranged inside the housing 10 by being inserted through the communication hole 14. The rear side of the housing 10 may be formed to extend so as to insert and arrange the ventilation portion 20, and the communication hole 14 may be formed at the rear end portion of the extended portion. The upper side of the extended portion may be formed to be open so that the ventilation portion 20 is exposed to the open upper side of the housing 10 by rotation, and the opened surface may be formed to be connected to the surface covered by the housing door 12. That is, the upper side of the housing 10 may be formed to be completely open, but at least a portion thereof may be opened and closed by the housing door 12, and the remaining portion may be opened and closed by the ventilation portion 20.

[0060] The hose 30 may be connected to the inflow portion 24 of the ventilation portion 20. The hose 30 may be used as a duct connecting the air outlet of the air conditioning device and the ventilation portion 20, and the hose 30 may be formed to be movable or deformable. That is, the hose 30 may be made of a material whose shape is freely deformable, such as rubber, so as to move or change shape in response to the rotation of the ventilation portion 20.

[0061] As shown in the drawings, when the vent portion 20 is arranged at the second position by being rotated, the hose 30 may be inserted into the housing 10 through the communication hole 14 and arranged according to the position of the inflow portion 24 of the vent portion 20 .

[0062] refer to Figure 3 , when the ventilation part 20 is arranged in the first position, the cover 22 can be arranged in the horizontal direction so that the ventilation part 20 is not exposed to the outside of the housing 10, and thus can be arranged on the same plane as the housing door 12 that closes the upper side of the opening of the housing 10. In this way, a hidden design of the ventilation module 100 can be achieved. Since the discharge part 26 of the ventilation part 20 arranged in the first position is directed to the inside of the housing 10, the cooled and heated air can be discharged into the housing 10, and the temperature inside the housing 10 can be adjusted.

[0063] refer to Figure 4When the ventilation portion 20 is arranged in the second position, the ventilation portion 20 can be exposed to the open upper side of the housing 10. The ventilation portion 20 can be rotated using the point where the cover 22 contacts the inflow portion 24 as a rotation axis, the inflow portion 24 can be arranged in a horizontal direction so as to be arranged on the same plane as the housing door 12 that closes the open surface of the housing 10, and the ventilation portion 20 can be exposed to the outside of the housing 10.

[0064] Since the discharge portion 26 of the ventilation portion 20 arranged in the second position is directed toward the interior of the vehicle, and the inflow portion 24 is rotated and moved to the upper side of the shell 10, the hose 30 connected to the inflow portion 24 can also be inserted and moved to the interior of the shell 10 accordingly, and air is allowed to flow in through the inflow portion 24, so that the air is discharged to the discharge portion 26.

[0065] Figure 5 is a view showing that a ventilation portion of a ventilation module according to an embodiment of the present invention is arranged in a first position; and Figure 6 2 is a view showing that the ventilation part of the ventilation module according to one embodiment of the present invention is arranged in the second position.

[0066] refer to Figure 5 and Figure 6 , fixing pins 29 may be formed on both side surfaces of the ventilation portion 20. Since the ventilation portion 20 can rotate inside the housing 10, the ventilation portion 20 needs to be maintained in a fixed state at the first position and the second position. The fixing pins 29 may extend from both side surfaces of the ventilation portion 20, and the fixing pins 29 may fix the ventilation portion 20 by being stuck in grooves formed on the inner surface of the housing 10.

[0067] The fixing pin 29 and the hinge 28 may be arranged near respective vertices of a triangle, which is the cross-sectional shape of the ventilating portion 20, and the fixing pin 29 and the hinge 28 may fix the ventilating portion 20 to correspond to the first position and the second position. Figure 5 As shown, when the ventilation portion 20 is arranged in the first position, the fixing pin 29 formed at the vertex formed by the cover 22 and the discharge portion 26 can maintain the state of being arranged in the first position by being stuck on the housing 10. In this case, the cover 22 can be arranged in the horizontal direction, and thus the ventilation portion 20 may not be exposed to the open upper side of the housing 10.

[0068] like Figure 6As shown, when the ventilation portion 20 is arranged in the second position, the fixing pin 29 formed at the vertex formed by the inflow portion 24 and the discharge portion 26 can be stuck on the housing 10. The ventilation portion 20 can maintain the state of being arranged in the second position. In this case, since the inflow portion 24 can be arranged in the horizontal direction, the ventilation portion 20 can be completely exposed to the open upper side of the housing 10, and the discharge portion 26 is opened toward the interior of the vehicle, the air temperature inside the vehicle can be controlled.

[0069] refer to Figure 6 , ribs 27 for guiding the direction of air may be formed in the discharge portion 26. Since the discharge portion 26 is formed to be open, the discharge portion 26 may be formed to be completely open except for the edge without the ribs 27. Alternatively, when it is desired to provide indirect wind to the passengers, a mesh cover may be arranged on the open side of the discharge portion 26 to achieve the indirect wind.

[0070] Alternatively, as shown in the figure, the ribs 27 may be formed to discharge air in a direction perpendicular to the opening side of the discharge portion 26. The ribs 27 may be formed parallel to each other and may also be formed to spread in a radial direction relative to the hinge 28 of the vent portion 20.

[0071] Figure 7 is a view showing a housing door of a ventilation module according to another embodiment of the present utility model; and Figure 8 is a view showing a cross section of a housing door of a ventilation module according to another embodiment of the present invention.

[0072] The housing door 12 opens and closes the open side of the housing 10, but needs to be maintained in a fixed state when closed. This is because when the vehicle body shakes due to the movement of the vehicle, there is a risk that the items stored inside the housing 10 may be separated to the outside of the housing 10.

[0073] refer to Figure 7 and Figure 8 A fastener 40 for fixing the housing door 12 in a closed state may be formed on one side of the housing door 12. The fastener 40 may extend by receiving an elastic force from an elastic body 42 disposed on one side of the fastener 40, and the housing door 12 may be fixed in a manner that the fastener 40 extends and is caught in a fastening groove 15 formed in the housing 10.

[0074] When the user opens the housing door 12 to open the housing 10, the user can push the fastener 40 in the direction opposite to the elastic force provided by the elastic body 42 so that the fastener 40 is separated from the fastening groove 15, and then lift the fastener 40 upward to open the housing door 12. The elastic body 42 may be a spring and is not limited as long as the elastic body 42 can provide the elastic force to the fastener 40 so that the fastener 40 is inserted into the fastening groove 15.

[0075] Fig. 9 2 is a view showing a ventilation part of a ventilation module according to another embodiment of the present invention.

[0076] refer to Fig. 9 In the ventilation part 20 of the ventilation module 100 according to another embodiment of the present invention, the discharge part 26 may be formed to be curved. Since the discharge part 26 is a part for discharging air, the discharge part 26 may be formed to have a curvature that diffuses air over a wide range.

[0077] In the ventilation part 20, since the discharge part 26 connects the inflow part 24 and the cover 22, the discharge part 26 may be curved to form a fan shape. When the ventilation part 20 is formed in a fan shape, air may be discharged as if the air diffuses in a radial direction in the fan shape. In order to widen the discharge direction of the air, ribs 27 may be formed in the discharge part 26 in a radial direction.

[0078] Fig.10 2 is a view showing a ventilation module according to still another embodiment of the present invention.

[0079] refer to Fig.10 , the hose 30 connected to the inflow portion 24 of the ventilation portion 20 may be formed to be folded when the ventilation portion 20 is arranged in the first position, and to be unfolded accordingly when the ventilation portion 20 is arranged in the second position. The hose 30 may be made of a material such as rubber, and folds may be formed at the end of the hose 30 connected to the inflow portion 24 so that the hose 30 is folded in the direction of the folds.

[0080] Fig.10 The ventilation portion 20 in the figure is shown to have the shape of an acute triangle rather than a right triangle. That is, the angle at which the cover 22 intersects the inflow portion 24 may not be perpendicular, but may be less than 90 degrees. In this case, the angle at which the ventilation portion 20 rotates may be reduced. Alternatively, the angle at which the cover 22 intersects the inflow portion 24 may be formed to be greater than 90 degrees, and in this case, the angle at which the ventilation portion 20 needs to be rotated in order to be exposed to the open upper side of the housing 10 may become even larger accordingly.

[0081] According to one embodiment of the utility model, the air conditioning of the interior of the vehicle can be facilitated by arranging the ventilation part in a rotatable manner inside the shell, and at the same time, a hidden design is implemented by inserting the ventilation part into the shell, and it can have functions other than vehicle air conditioning by allowing cooling of the interior of the shell.

[0082] Various beneficial advantages and effects of the present invention are not limited to the above contents and should be easily understood through the description of the detailed embodiments of the present invention.

[0083] Although specific embodiments of the present invention have been described above, it should be understood that various changes and modifications may be made to the present invention by those skilled in the art without departing from the spirit and scope of the present invention as claimed.
