Description

Technical Field

[0001] The present invention relates to a vehicle vent, and more particularly, to a vehicle vent as an electric windless vent, which utilizes a spline mechanism to form an idle rotation interval of a driving rotator, thereby preventing operational conflicts between a cover and an air duct during switching between a normal mode and a windless mode. 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 for cooling or heating, 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 a HVAC system can remove frost or fog formed on the windshield and vehicle glass, thereby ensuring driving safety.

[0004] Typically, an HVAC system consists of an air conditioning box, which is equipped with indoor and outdoor units, an evaporator, and a heater core, which heat or cool the air before supplying it to the vehicle.

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

[0006] In the early stages of using air conditioning, the cold air from the HVAC system can make users feel comfortable through rapid cooling. However, in the middle or late stages of using air conditioning, users will feel more uncomfortable, such as being too cold. At this time, users must stop running the HVAC system.

[0007] That is, since the cooling or heating of the HVAC system directly contacts the user's body, the user may feel uncomfortable, so the HVAC system needs to be frequently turned on / off. In addition, the cooling or heating will give the user a drafty feeling, which is also one of the causes of air conditioning sickness.

[0008] Therefore, there is a need for a vent with a windless mode so that users do not feel uncomfortable due to cooling or heating. In this case, the switch between the normal mode and the windless mode can be achieved electrically or manually, and it is required that when switching the modes, there is no conflict between the movement of the internal air duct and the movement of the external cover.

[0012] Purpose of the Invention

[0013] The present invention is used to solve the problems in the above-mentioned prior art. Its purpose is to provide a vehicle vent as an electric windless vent, which uses a groove wheel mechanism to form a rotation idle (IDLE) interval of the driving rotator, thereby preventing operational conflicts between the cover and the air duct during the switching process between the general mode and the windless mode.

[0014] Technical solutions to the problem

[0018] A vehicle vent according to an embodiment of the present invention is characterized in that the driving rotator may have a first side formed with a first pin, and a second side formed with a second pin, a first slot engaged with the first pin is formed in the first sheave mechanism, and a second slot engaged with the second pin is formed in the second sheave mechanism.

[0019] The vehicle vent of one embodiment of the present invention may further include a spacer, which is arranged on both sides of the external air duct to connect the upper and lower parts of the external air duct, and a curved guide groove is formed on the inner side of the spacer to guide the rotation of the cover, and a first guide pin is formed on the side of the cover to be inserted into the guide groove.

[0020] The vehicle vent of one embodiment of the present invention may further include a guide link, one end of which is coupled to the rotating shaft of the first groove pulley mechanism, a long hole is formed in the middle part along the length direction, and a second guide pin is formed on the side of the cover to be inserted into the long hole, and the guide link transmits the rotational force based on the rotation of the first groove pulley mechanism to the cover.

[0021] The vehicle air vent according to an embodiment of the present invention is characterized in that the first sheave mechanism can be rotatably coupled to the spacer.

[0022] The vehicle vent according to an embodiment of the present invention is characterized in that the length of the long hole can be set to a length that compensates for positional changes in the longitudinal direction of the side portion of the cover when the cover rotates.

[0023] The vehicle vent according to an embodiment of the present invention is characterized in that the front portion of the cover can be formed in a grid shape, so that in a windless mode, the warm air or cold air supplied from the outer air duct and the inner air duct is dispersed and supplied to the user.

[0024] Effects of the Invention

[0025] According to one aspect of the present invention, a rotation IDLE section of the driving rotator is formed by using a sheave mechanism, thereby preventing operational conflict between the cover and the air duct during switching between the normal mode and the windless mode.

[0026] In addition, users can easily adjust the normal mode and windless mode by operating the button according to their needs to reduce the discomfort caused by cold air.

[0027] Furthermore, since the vehicle vent is operated in the windless mode, the user does not need to operate the vent power supply, thereby maintaining a constant temperature inside the vehicle.

[0028] It should be understood that the effects of the present invention are not limited to the above-mentioned effects, but also include all effects that can be derived from the inventive structure described in the detailed description of the present invention or the claims.

[0036] The present invention will be described below with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Portions of the drawings not relevant to the description have been omitted to facilitate a clearer description of the present invention. Similar reference numerals are used throughout the specification for similar components.

[0037] Throughout this specification, when a component is said to be "connected to" another component, this includes not only "direct connection" but also "indirect connection" where other components are interposed between the two components. Furthermore, when a component is said to "comprise" other constituent elements, this means that the component may further comprise other constituent elements, and does not exclude other constituent elements, unless otherwise specifically stated.

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0039] Figure 1 (a) and (b) are perspective views showing a no-wind mode and a normal mode of a vehicle vent according to an embodiment of the present invention, respectively; Figure 2 is a perspective view showing a vehicle vent with the external air duct removed according to an embodiment of the present invention; Figure 3 FIG. 1 is an exploded view showing a vehicle air vent according to an embodiment of the present invention.

[0040] According to an embodiment of the present invention, a vehicle vent 1000 is located on the front side panels of a driver and a passenger in a vehicle, and can supply heating or cooling air into the vehicle.

[0041] Reference Figures 1 to 3 The vehicle vent 1000 of the present invention includes an outer air duct 100 , an inner air duct 200 , a driving rotator 300 , a first sheave mechanism 400 , a second sheave mechanism 500 , a cover 600 , a side gear 700 , and a pinion 710 .

[0042] More specifically, the vehicle vent 1000 of the present invention is constructed to include: an outer air duct 100 for air flow; an inner air duct 200 arranged inside the outer air duct 100 and formed with a rack 210; a driving rotator 300 installed on one side of the outer air duct 100; a first grooved wheel mechanism 400 that rotates as the driving rotator 300 rotates; a second grooved wheel mechanism 500 that rotates as the driving rotator 300 rotates; a cover 600 that rotates as the first grooved wheel mechanism 400 rotates and simultaneously opens and closes the air outlet portion of the outer air duct 100; a side gear 700 that rotates as the second grooved wheel mechanism 500 rotates; and a small gear 710 that is coupled to the side gear 700 through a pin 720 so as to rotate together, and moves the inner air duct 200 in the front and rear directions while engaging with the rack 210.

[0043] The vehicle vent 1000 of the present invention is electrically operated and can be switched between a general mode for blowing air or a windless mode for no wind according to a user's operation.

[0044] On the one hand, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) defines wind speeds below 0.15 m / s, which are free of standard cold draft (air movement caused by temperature differences due to refrigeration), as "still air." In one embodiment of the present invention, this should be understood to include wind speeds below 0.15 m / s and above.

[0045] Hereinafter, the downstream side in the air discharge direction is defined as the front, and the upstream side is defined as the rear.

[0046] Figure 1 (a) shows the situation when the vehicle vent 1000 is in a general mode. At this time, the cover 600 opens the air outlet portion of the outer air duct 100, and the inner air duct 200 is located in the front of the inner portion of the outer air duct 100.

[0047] Figure 1 (b) shows the situation when the vehicle vent 1000 is in a windless mode. At this time, the cover 600 closes the air outlet portion of the outer air duct 100, and the inner air duct 200 is located at the rear of the inner portion of the outer air duct 100.

[0048] In this case, the front portion 610 of the cover 600 is formed in a mesh shape, so that in the windless mode, the air blown out from the outer air duct 100 and the inner air duct 200 can be dispersed to reduce the wind speed. In other words, the cover 600 can discharge the air with reduced wind speed to the user in the middle or late stages of air conditioning, thereby reducing the user's discomfort caused by the cold air.

[0049] In other words, in the early stage of air conditioning, the general mode can be used to open the air outlet part of the cover 600, so as to continue cooling at a certain wind speed. Then, in the middle or late stage of air conditioning, the windless mode can be used to close the air outlet part of the cover 600, so as to achieve windless cooling at a reduced wind speed.

[0050] The mode switching operation of the vehicle vent 1000 of the present invention will be described in detail later.

[0051] 4 (a) and (b) are respectively an outer side view and an inner side view of a vehicle vent according to an embodiment of the present invention with the outer air duct and the spacer omitted; Figure 5 is a perspective view of a vehicle vent with the external air duct omitted according to an embodiment of the present invention; Figure 6 They are respectively partial enlarged views of a vehicle vent according to an embodiment of the present invention.

[0052] Reference Figures 1 to 6 The outer air duct 100 can cooperate with an air conditioning device (not shown) for supplying air. The outer air duct 100 can be formed into a hollow shape with front and back openings. The cross section of the outer air duct 100 can be generally formed into a quadrilateral or polygon, but is not limited thereto.

[0053] As an example, the configuration may be such that 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 vehicle engine refrigerant flows for heat exchange, and then the cold air or warm air is distributed into the vehicle in various directions through air vents connected to various components in the vehicle, thereby achieving cooling or heating in the vehicle.

[0054] The above-mentioned cooling and heating cycles are well-known technologies and will not be described in detail here.

[0055] The outer air duct 100 may be composed of an upper air duct 110 and a lower air duct 120. The upper air duct 110 and the lower air duct 120 are connected by spacers 800 respectively coupled to both sides.

[0056] That is, the spacers 800 are disposed on both sides of the external air duct 100 , thereby connecting the upper portion and the lower portion of the external air duct 100 .

[0057] The inner air duct 200 may be disposed inside the outer air duct 100 and move toward the front or rear of the outer air duct 100 according to different modes.

[0058] In a general mode, the inner air duct 200 is located in front of the outer air duct 100 ; in a windless mode, the inner air duct 200 is located in the rear of the outer air duct 100 .

[0059] A rack 210 may be formed at the lower portion of the inner duct 200. As will be described below, the rack 210 of the inner duct 200 engages with the pinion 720, thereby moving the inner duct 200 toward the front or rear of the outer duct 100.

[0060] In this case, an insertion hole 121 may be formed at the lower portion of the lower air duct 120 , and the pinion 720 may be engaged with the rack 210 of the inner air duct 200 disposed inside the outer air duct 100 through the insertion hole 121 .

[0061] The driving rotator 300 may be rotatably installed at one side of the outer air duct 100 .

[0062] A motor (not shown) may be connected to the rotation shaft of the driving rotator 300 , and when the motor (not shown) is driven, the driving rotator 300 rotates in a clockwise direction or a counterclockwise direction by a certain angle.

[0063] When the rotator 300 is driven to rotate in the clockwise direction O, the vehicle vent 1000 switches from the windless mode to the normal mode; when the rotator 300 is driven to rotate in the counterclockwise direction C, the vehicle vent 1000 switches from the normal mode to the windless mode.

[0064] Meanwhile, the driving rotator 300 has a first side 310 and a second side 320. The first side 310 is formed with a first pin 311, and the second side 320 is formed with a second pin 321.

[0065] The first sheave mechanism 400 is rotatably installed at one side of the outer air duct 100 and rotates along with the rotation of the driving rotator 300 .

[0066] More specifically, the first sheave mechanism 400 may be rotatably mounted on the spacer 800. A first slot 410 is formed on the first sheave mechanism 400. When the rotator 300 is driven to rotate, the first slot 410 engages with the first pin 311, thereby rotating the first sheave mechanism 400.

[0067] The cover 600 rotates along with the rotation of the first sheave mechanism 400 , and opens and closes the air outlet portion of the external air duct 100 .

[0068] That is, when the vehicle vent 1000 is in a general mode, the cover 600 opens the air outlet portion of the outer air duct 100 ; when it is in a windless mode, the cover 600 closes the air outlet portion of the outer air duct 100 .

[0069] The cover 600 may be composed of a front portion 610 and two side portions 620. As described above, the front portion 610 may be formed in a grid shape, and the side portions 620 may be formed with a first guide pin 621 and a second guide pin 622.

[0070] On the one hand, the cover 600 may be connected to the first sheave mechanism 400 via the guide link 900. That is, the guide link 900 may transmit the rotational force based on the rotation of the first sheave mechanism 400 to the cover 600.

[0071] One end portion of the guide link 900 may be coupled to the rotation shaft of the first sheave mechanism 400 , and a long hole 910 is formed in a middle portion of the guide link 900 along a length direction.

[0072] The second guide pin 622 of the cover 600 may be inserted into the long hole 910 of the guide link 900 and guided along the long hole 910 in the length direction.

[0073] In this case, the length of the long hole 910 may be set to a length that compensates for a position change in the length direction of the side portion 610 when the cover 600 rotates.

[0074] Meanwhile, a curved guide groove 810 for guiding the rotation of the cover 600 may be formed inside the spacer 800 .

[0075] The first guide pin 621 of the cover 600 may be inserted into the guide groove 810 and guided in a rotation direction along the guide groove 810 .

[0076] That is, the rotation operation of the cover 600 may be achieved by driving the rotator 300 , the first sheave mechanism 400 , and the guide link 900 in sequence.

[0077] The second sheave mechanism 500 is rotatably installed at one side of the outer air duct 100 and rotates as the driving rotator 300 rotates.

[0078] More specifically, the second sheave mechanism 500 is formed with a second slot 510 and a serration 520 . When the rotator 300 is driven to rotate, the second slot 510 engages with the second pin 311 , thereby achieving the rotation of the second sheave mechanism 500 .

[0079] The side gear 700 is rotatably mounted on one side of the outer air duct 100 and meshes with the serrated portion 520 as the second sheave mechanism 500 rotates.

[0080] In this case, the side gear 700 installed on one side of the outer duct 100 may be connected to the side gear 700 installed on the other side through the pin 720. Thus, the rotational motions on both sides of the cover 100 may be synchronized.

[0081] The pinion gear 710 is coupled to the side gear 700 via a pin 720 , thereby rotating together.

[0082] More specifically, the pinion 710 is rotatably disposed at the center of the pin 720 , and when rotating, engages with the rack 210 of the inner duct 200 to move the inner duct 200 in the front-rear direction.

[0083] That is, the inner air duct 200 can be moved in the front-rear direction by driving the rotator 300 , the second sheave mechanism 500 , the side gear 700 , and the pinion gear 710 in sequence.

[0084] 4 (a), the rotation idle interval θ is formed between the driving rotator 300 and the first sheave mechanism 400 and the second sheave mechanism 500, so that the rotation of the cover 600 and the front-rear movement of the inner duct 200 has a predetermined time difference between the action.

[0085] More specifically, the rotation idle interval θ represents an angle formed by the second pin 321 of the driving rotator 300 and the second sheave mechanism 500 with the rotation axis of the driving rotator 300 as the center when the first pin 311 of the driving rotator 300 is engaged with the first sheave mechanism 400 in the switching mode.

[0086] In other words, by forming the rotation idle interval θ, the rotation of the cover 600 and the front-to-back movement of the inner duct 200 can be performed with a predetermined time difference, thereby preventing a conflict between the cover 600 and the inner duct 200 during mode switching.

[0087] At this time, the rotation idle interval θ can be between 25° and 45°. If the rotation idle interval θ is less than 25°, the risk of conflict between the cover 600 and the inner air duct 200 during the switching process increases; if the rotation idle interval θ exceeds 45°, the mode switching will be delayed, resulting in a poor operating experience.

[0088] 7( a )-( d ) are flow charts illustrating the operation process of the vehicle vent according to one embodiment of the present invention.

[0089] The following describes the operation process of switching from the windless mode to the normal mode with reference to Figures 4(a)-(b) and Figures 7(a)-(d). Switching from the normal mode to the windless mode is the reverse process of the above operation process.

[0090] FIG7( a ) shows the vehicle vent 1000 in the windless mode, with the cover 600 closing the air outlet portion of the exterior duct 100, and the interior duct 200 positioned at the rear of the exterior duct 100. Furthermore, a rotation idle region θ is formed between the drive rotator 300 and the first and second sheave mechanisms 400 and 500.

[0091] When the user sets the mode to the normal mode through a switch (not shown) such as a button, the motor (not shown) is driven by an electric signal, thereby rotating the driving rotator 300 connected to the motor in the clockwise direction O.

[0092] As the first pin 311 of the driving rotator 300 is inserted into and engaged with the first slot 410 of the first sheave mechanism 400, the first sheave mechanism 400 rotates counterclockwise C, thereby the cover 600 rotates counterclockwise C through the guide link 900 combined with the first sheave mechanism 400, thereby opening the air outlet portion of the outer air duct 100.

[0093] Figure 7(b) shows the situation when the second pin 321 of the driving rotator 300 passes through the rotation idle interval θ and begins to engage with the second sheave mechanism 500. When the cover 600 rotates to this position, the inner duct 200 inside the outer duct 100 remains in its initial position and does not move forward. In other words, as the rotation idle interval θ is formed, a time difference is generated between the rotation of the cover 600 and the movement of the inner duct 20.

[0094] 7(c) and (d), as the second pin 321 of the drive rotator 300 is inserted into and meshed with the second slot 510 of the second sheave mechanism 500, the second sheave mechanism 500 rotates counterclockwise (C), thereby rotating the pinion 710 connected to the two side gears 700 via the pin 720 in the clockwise (O) direction. Consequently, as the pinion 710 meshes with the rack 210 at the bottom of the inner duct 200, the inner duct 200 moves forward. Simultaneously, as the cover 600 continues to rotate counterclockwise (C), the air outlet portion is fully opened.

[0095] Thus, the electric vehicle vent 1000 according to the present invention forms the rotation idle section θ to prevent the rotation of the cover 600 and the movement of the inner duct 200 from conflicting during mode switching, thereby improving the overall operability of the vehicle vent 1000.

[0096] The above description of the present invention is for illustrative purposes only. Those skilled in the art will appreciate that the present invention can be easily modified into other specific forms without changing the technical spirit or basic features of the present invention. Therefore, it should be understood that the above embodiments are for illustrative purposes only and not for restrictive purposes in all aspects. For example, each component described in a monomeric form can be implemented in a dispersed form, and similarly, the components in a dispersed form can also be implemented in a combined form.
