Description

Technical Field

[0001] The present invention relates to a vent for a vehicle, and more particularly, to a vent for a vehicle as a multi-layer hidden vent, which is constructed of a plurality of layers having meshes formed therein, which are arranged one after another behind a cover and operated in a stepwise manner, thereby adjusting the wind direction. Background Art

[0002] Vehicles are equipped with a heating, ventilation, and air conditioning (HVAC) system that generates warm or cold air and supplies it to the interior of the vehicle to achieve heating or cooling, or to keep the interior of the vehicle comfortable at all times, regardless of the external environment.

[0003] Furthermore, when the outside temperature is low, such as on rainy days or in winter, such an HVAC system can also be used to ensure driving safety by removing frost or fog formed on the windshield and vehicle glass.

[0004] Typically, an HVAC system includes an air conditioning box, which is equipped with indoor and outdoor units, an evaporator, and a heater core, etc. for sucking in external air or internal air and sending the external air or internal air to the air conditioning box. The air is then supplied to the interior of the vehicle after being heated or cooled.

[0005] The air cooled or heated by the HVAC system is supplied to the interior of the vehicle through an air vent for the vehicle that communicates with the air conditioning box, thereby achieving cooling and heating in the vehicle.

[0006] Conventional vents typically have blades that adjust airflow direction exposed to the outside of the vent. This requires not only horizontal blades but also vertical blades. This complicates the internal structure of the vent, which regulates airflow direction. Furthermore, the exposed blades can lead to foreign matter entering the spaces between the blades, reducing vent performance.

[0035] The present invention will be described below with reference to the accompanying drawings. However, the present invention can be embodied in various different forms and is not limited to the embodiments described herein. Also, parts irrelevant to the description are omitted from the drawings to help clarify the description of the present invention, and like reference numerals are used for like parts throughout the specification.

[0036] Throughout the specification, when a part is referred to as being "connected to" another part, it includes not only "direct connection" but also "indirect connection" with other parts intervening between the two parts. Also, when it is stated that a part "includes" other components, this does not mean excluding other components, but may mean further including other components, unless otherwise stated to the contrary.

[0037] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0038] Figure 1 It is a perspective view of a vent for a vehicle according to an embodiment of the present invention; Figure 2 It is an exploded view of a vent for a vehicle according to an embodiment of the present invention; Figure 3 It is a perspective view of a vent for a vehicle according to an embodiment of the present invention, omitting the duct and the cover; Figure 4 It is an exploded view showing the connection structure of multiple layers according to an embodiment of the present invention.

[0039] A vent Figures 1 to 4 for a vehicle according to an embodiment of the present invention is located on the front panel of the driver and passengers in the vehicle, and thus can supply warm air or cold air to the vehicle interior.

[0040] Next, the downstream side in the air discharge direction is defined as the front, and the upstream side is defined as the rear.

[0041] Referring to Figures 1 to 4 , the vent Figures 1 to 4 for a vehicle of the present invention includes a duct 100, a cover 200, multiple layers 300, and a shaft 400.

[0042] More specifically, the vent 1000 for a vehicle according to the present invention includes: a duct 100 through which air flows; a cover 200 disposed on the front side of the duct 100 and having an outflow mesh F formed therein through which air flows out; a plurality of layers 300 disposed one after another behind the cover 200 and having guiding meshes G formed therein for guiding air therethrough; and a shaft 400 passing through the plurality of layers 300 and overlapping each other in the front-rear direction through the guiding meshes G to form at least one air flow passage S, and the vent 1000 for a vehicle is configured such that according to the operating direction of the shaft 400, the plurality of layers 300 move in a step-by-step manner to change the direction of the air flow passage S.

[0043] The duct 100 can cooperate with an air conditioning device (not shown) that supplies air. The duct 100 can be formed in a hollow shape that is open at both the front and the rear. The cross-section of the duct 100 can be generally formed in a quadrilateral or polygonal shape, but is not limited thereto.

[0044] As an example, it can be configured such that the air introduced by a blower unit (not shown) selectively passes through an evaporator through which a refrigerant flows or a heater core through which a coolant of a vehicle engine flows for heat exchange, and then, the cold or warm air is distributed in all directions in the vehicle through an air vent communicating with various components in the vehicle, thereby achieving refrigeration or heating in the vehicle.

[0045] The above refrigeration and heating cycles are well-known technologies and will not be described in detail herein.

[0046] The cover 200 is disposed on the front side of the duct 100 and can be fixed by a fixed end 110. The fixed end 110 can be formed in the front frame of the duct 100 and can form holes so that fastening components such as screws can be inserted.

[0047] An outflow mesh F for air to flow out can be formed on the cover 200. More specifically, an outflow grid 210 can be formed on the cover 200, and the outflow grid 210 can be arranged in a grid pattern extending diagonally, thereby forming a plurality of diamond-shaped outflow meshes F. However, the shape of the outflow mesh F is not limited thereto and can be formed in various shapes according to the arrangement pattern of the outflow grid 210.

[0048] A plurality of layers 300 can be disposed one after another behind the cover 200, and guiding meshes G for guiding air therethrough are formed on each of the plurality of layers 300.

[0049] In this case, the plurality of layers 300 can include a first layer 310, a second layer 320, a third layer 330, and a fourth layer 340 starting from the front.

[0050] More specifically, guide grids 311, 321, 331, and 341 may be respectively formed in each of the layers 310, 320, 330, and 340. The guide grids 311, 321, 331, and 341 may be arranged in a grid pattern extending diagonally, thereby forming a plurality of diamond-shaped guide mesh holes G. However, the shape of the guide mesh holes G is not limited thereto and may be formed into various shapes according to the arrangement pattern of the guide grids 311, 321, 331, and 341.

[0051] As each of the layers 310, 320, 330, and 340 is provided layer by layer, the guide mesh holes G overlap each other in the front-rear direction. Thus, an air flow passage S for air movement may be formed in front of the interior of the duct 100.

[0052] The fourth layer 340 is the rearmost layer. Insertion protrusions 343 may be disposed on both sides of the fourth layer 340 for insertion and connection to slots 522 formed on both sides of a layer carrier 500 described later.

[0053] The shaft 400 is disposed to pass through the cover case 200 and the plurality of layers 300.

[0054] More specifically, the shaft 400 is disposed to pass through the center of the cover case 200 and the center of the plurality of layers 300, and each of the layers 310, 320, 330, and 340 moves in a stepwise manner according to the operation direction of the shaft 400, thereby changing the direction of the air flow passage S.

[0055] A knob 410 may be formed at one end of the shaft 400, and a universal joint 420 may be formed at the other end. The universal joint 420 is a well-known technology and will not be described herein in detail.

[0056] The knob 410 is disposed to be exposed outside the cover case 200. In this case, a user may directly hold the knob 410 and then adjust the wind direction of the vent 1000 for a vehicle by operating it up, down, left, or right, so that the direction of the air supplied into the vehicle can be selected up, down, left, or right. A plurality of grooves, separate anti-slip members, etc. may be formed on the surface of the knob 410 to prevent the user's hand from slipping.

[0057] Refer to Figures 2 to 4 , the vent 1000 for a vehicle according to the present invention may further include a layer carrier 500, a layer link 600, and a link stopper 700.

[0058] The layer carrier 500 is a component that transmits the operating force of the shaft 400 to the plurality of layers 300 when the shaft 400 is operated up and down. The layer carrier 500 has a horizontal portion 510 and both side portions 520.

[0059] A through-hole 511 may be formed in the center of the horizontal portion 510 of the layer carrier 500, and the shaft 400 is inserted through the through-hole 511. In this case, the through-hole 511 may be in the shape of a long hole that is longer in the horizontal direction than in the vertical direction. Also, the vertical diameter of the through-hole 511 may correspond to the diameter of the shaft 400.

[0060] Coupling protrusions 521 and slots 522 may be formed on both side portions 520 of the layer carrier 500. Among them, the coupling protrusion 521 can be coupled to the pipe 100, and the insertion protrusion 343 of the fourth layer 340, which is the last layer, can be inserted into the slot 522. That is to say, the layer carrier 500 can be coupled to the pipe 100 through the coupling protrusion 521 and coupled to the fourth layer 340, which is the last layer, through the slot 522.

[0061] In other words, when the shaft 400 operates up and down, the layer carrier 500 rotates about the coupling protrusion 521 coupled to the pipe 100 as the rotation axis. Thus, the fourth layer 340, which is assembled through the slot 522 and is the last layer, moves linearly in the up and down directions.

[0062] Also, when the shaft 400 operates left and right, the operating force of the shaft 400 is directly transmitted to the fourth layer 340, which is the last layer. Thus, the fourth layer 340 moves linearly in the left and right directions. At this time, since the through-hole 511 is in the shape of a long hole in the left and right directions, the operating force of the shaft 400 is not transmitted to the layer carrier 500.

[0063] Meanwhile, the layer link 600 is a component configured to connect multiple layers 300, and the layer link 600 can be respectively arranged on both sides of the multiple layers 300.

[0064] More specifically, the layer link 600 can be located between the second layer 320 and the third layer 330, and can be provided with: a first protrusion 610 coupled to the first layer 310; a second protrusion 620 coupled to the second layer 320; a third protrusion 630 coupled to the third layer 330; a fourth protrusion 640 coupled to the fourth layer 340; and a fifth protrusion 650 coupled to the cover 200. Each protrusion 610, 620, 630, 640, 650 of the layer link 600 can be inserted and coupled to holes formed in each of the layers 310, 320, 330, 340 and the cover 200, thereby connecting the multiple layers 300 to each other.

[0065] In other words, when the fourth layer 340, which is the last layer, moves up and down under the action of the shaft 400 and the layer carrier 500, each of the layers 310, 320, 330 connected by the layer link 600 moves in a step-by-step manner, thereby changing the wind direction in the up and down directions.

[0066] Also, when the fourth layer 340, which is the last layer, moves left and right under the action of the shaft 400, the respective layers 310, 320, 330 connected by the layer link 600 move in a step-by-step manner, thereby changing the wind direction in the left and right directions.

[0067] The link stopper 700 is a component that assists in connecting multiple layers 300, and the link stopper 700 can be provided on the upper or lower part of the multiple layers 300.

[0068] Both end portions of the link stopper 700 are respectively provided with bent portions 710 formed by bending, and are generally formed into a shape. Also, the link stopper 700 can be made of elastic steel so as to be able to achieve a predetermined deformation when compressed.

[0069] That is, the bent portions 710 of the link stopper 700 are inserted through the insertion holes 312, 322, 332, 342 formed in the respective layers 310, 320, 330, 340, thereby connecting the respective layers 310, 320, 330, 340. From the front layer to the rear layer, the respective insertion holes 312, 322, 332, 342 formed in the respective layers 310, 320, 330, 340 are formed such that the diameters in the left and right directions can gradually increase.

[0070] Also, when the shaft 400 operates left and right, the link stopper 700 functions as a stopper for restricting the movement range of the respective layers 310, 320, 330, 340 in the left and right directions.

[0071] Figure 5 is a cross-sectional view showing the operation process of the air guide according to an embodiment of the present invention.

[0072] Referring to Figure 5 , the vent 1000 for a vehicle according to the present invention may further include a rotating shaft 430, an air guide 440, and a horizontal shaft 450.

[0073] One end of the rotating shaft 430 can be coupled to the universal joint 420, and a rotating shaft gear 431 can be formed in the other end of the rotating shaft 430.

[0074] The air guide 440 can be rotatably coupled to the horizontal shaft 450, and can be composed of a first air guide 441 and a second air guide 442.

[0075] The air guide 440 can be formed in a quadrilateral plate shape with a predetermined area to control the traveling direction of the air. Also, since the air guide 440 will be worn due to frequent rotation and friction, part or all of the air guide 440 can be made of wear-resistant materials such as rubber and silica gel.

[0076] In this case, a first horizontal shaft gear 441a meshing with the rotary shaft gear 431 may be formed on the first air guide 441, and a second horizontal shaft gear 442a meshing with the rotary shaft gear 431 may be formed on the second air guide 442.

[0077] Refer to Figure 5 , as the rotary shaft gear 431 rotates, the first horizontal shaft gear 441a and the second horizontal shaft gear 442a meshing therewith also rotate accordingly. When the first horizontal shaft gear 441a rotates, the first air guide 441 can rotate upward, and when the second horizontal shaft gear 442a rotates, the second air guide 442 can rotate downward.

[0078] In other words, when the user rotates the knob 410, the rotary shaft 430 can be rotated through the shaft 300, and as the rotary shaft 430 rotates, the first air guide 441 and the second air guide 442 meshing therewith can be rotated and moved.

[0079] Thus, the user can open or close the flow passage inside the duct 100 by rotating the knob 410 as needed, thereby adjusting the wind force.

[0080] Figure 6 is a cross-sectional view taken along line A-A of the vent for a vehicle according to an embodiment of the present invention; Figure 7 is a cross-sectional view taken along line B-B of the vent for a vehicle according to an embodiment of the present invention; Figure 8 is a cross-sectional view taken along line C-C of the vent for a vehicle according to an embodiment of the present invention; Figure 9 is a cross-sectional view taken along line D-D of the vent for a vehicle according to an embodiment of the present invention.

[0081] Refer to Figure 6 and Figure 7 The up-and-down direction operation of the vent 1000 for a vehicle according to the present invention will be described.

[0082] First, when the user operates the shaft 400 up and down via the knob 410, the layer carrier 500 rotates about the coupling protrusion 521 coupled to the duct 100. Thus, the fourth layer 340, which is the last layer assembled through the slot 522, moves linearly in the up-and-down direction. Then, when the fourth layer 340, which is the last layer, moves up and down, the respective layers 310, 320, 330 connected by the layer link 600 move in a stepwise manner, so that the respective guide meshes G are aligned in a stepwise manner, thereby changing the wind direction in the up-and-down direction.

[0083] Refer to Figure 8 and Figure 9The left-right direction operation of the vent 1000 for a vehicle according to the present invention will be described.

[0084] First, when a user operates the shaft 400 left and right via the knob 410, the operating force of the shaft 400 is directly transmitted to the fourth layer 340, which is the last layer. As a result, the fourth layer 340 moves linearly in the left-right direction. Then, when the fourth layer 340, which is the last layer, moves left and right, the respective layers 310, 320, and 330 connected by the layer link 600 move in a step-by-step manner, so that the respective guide meshes G are aligned in a step-by-step manner, thereby changing the wind direction in the left-right direction.

[0085] Thus, the vent 1000 for a vehicle according to the present invention is a multi-layer hidden vent. A plurality of layers 300 in which guide meshes G are formed are arranged one behind the other behind the cover 200 and can move in a step-by-step manner. Even without separate blades being exposed, the wind direction can be easily adjusted.

[0086] The above description of the present invention is for illustrative purposes only. Those of ordinary skill in the art to which the present invention pertains should understand that the present invention can be easily deformed into other specific forms without changing the technical spirit or basic characteristics of the present invention. Therefore, it should be understood that the above embodiments are illustrative in all respects and not restrictive. For example, each component described as an overall type can be implemented in a dispersed form, and similarly, components in a dispersed form can also be implemented in a combined form.

[0087] The scope of the present invention is defined by the claims described below, and all changes or deformations obtained from the meaning, scope, and equivalent concepts of the claims should be construed as being included within the scope of the present invention.
