Detailed Description

In order to facilitate understanding of the features of the present invention, a cup holder for a vehicle according to an embodiment of the present invention will be described in detail below.

In order to facilitate understanding of the embodiments described below, in the process of assigning reference numerals to constituent elements in respective drawings, the same reference numerals are assigned to the same constituent elements as much as possible even when the constituent elements appear in different drawings. In describing the present invention, a detailed description of a related known structure or function will be omitted when it is determined that the detailed description may obscure the gist of the present invention.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

fig. 2 and 3 are a perspective view and an exploded perspective view schematically showing a cup holder for a vehicle according to an embodiment of the present invention, and fig. 4 and 5 are a rear perspective view and a front perspective view schematically showing a holder portion of the cup holder for a vehicle, taken out of the cup holder. Fig. 6 is a perspective view schematically showing the lid member, the heat exchanging unit, and the air blowing unit taken out of the vehicle cup holder, and fig. 7 is a cross-sectional view schematically showing a cut-away portion of the area I-I' in fig. 2.

Referring to fig. 2 to 7, a cup holder 100 for a vehicle according to an embodiment of the present invention includes: a holder portion 200 having a first insertion portion 210 and a second insertion portion 220 into which a cup (not shown) can be inserted, and having a communication passage 230 formed so that the first insertion portion 210 and the second insertion portion 220 communicate with each other; a heat exchange unit 300 disposed on the bracket unit 200 and exchanging heat with the air passing through the communication flow path 230; a thermoelectric device 400 disposed at one side of the heat exchange part 300, for heating or cooling the heat exchange part 300; and an air blowing unit 500 disposed at the other side of the heat exchange unit 300, for generating a flow of air in the communication flow path 230.

The bracket unit 200 is disposed on a console of a vehicle, and includes a first insertion unit 210 and a second insertion unit 220 so as to be able to receive two cups. Further, since the first insertion portion 210 and the second insertion portion 220 communicate with each other through the communication flow path 230, air heated or cooled by one thermoelectric device 400 and one heat exchange portion 300 can flow into the first insertion portion 210 and the second insertion portion 220 through the communication flow path 230.

Such a bracket portion 200 may be formed by injection molding using resin in order to reduce cost. That is, in the present invention, the cup is kept warm by convection heat exchange, not by heat conduction, and thus, even if it is manufactured by using resin as a non-conductive material, the cup can be kept warm.

further, a guide piece 240 may be formed on the bracket unit 200 to protrude from the communication passage 230 so as to face the air blowing unit 500, so that air flowing through the air blowing unit 500 is divided and guided to the first insertion unit 210 and the second insertion unit 220. The edge portion of the guide piece 240 connected to the bracket portion 200 is formed in a circular arc shape to have a predetermined radius of curvature, so that the air flow is smoothly guided without forming a vortex at the edge portion.

The bracket unit 200 is provided with a circulation flow path for circulating air present inside the first insertion unit 210 and inside the second insertion unit 220.

That is, a first through hole 211 is formed in the first insertion portion 210 so as to be spaced apart from the communication flow path 230, and the first through hole 211 is connected to the communication flow path 230 from the outside of the first insertion portion 210, thereby forming a first circulation flow path 250. A second through hole 221 is formed in the second insertion portion 220 so as to be spaced apart from the communication channel 230, and the second through hole 221 is connected to the communication channel 230 from the outside of the second insertion portion 220 to form a second circulation channel 260.

In order to form such a circulation flow path, a partition member 270 protruding outward from the holder 200 such that the communication flow path 230, the first through hole 211, and the second through hole 221 are positioned inward, and a cover member 280 coupled to cover the partition member 270 are provided.

the cover member 280 may be configured to closely fix the heat exchange unit 300 to the holder 200, and may be formed with an insertion hole 281 configured to closely attach the thermoelectric device 400 to the heat exchange unit 300 by inserting one side surface of the thermoelectric device 400.

That is, after the heat exchange unit 300 is inserted into the bracket unit 200, the heat exchange unit 300 may be fixed by coupling the cover member 280 and the bracket unit 200, and one side surface of the thermoelectric device 400 may be closely attached to the heat exchange unit 300 by inserting the thermoelectric device 400 into the insertion hole 281 formed in the cover member 280. In this case, the other side surface of the thermoelectric device 400 is exposed to the outside of the cover member 280.

The heat exchange unit 300 includes: a substrate 310 formed in a planar shape so that the thermoelectric device 400 is closely attached to the substrate 310 in order to improve heat transfer efficiency with the thermoelectric device 400; and a heat exchange fin 320 formed by a plurality of fins protruding from the base plate in a vertical direction at predetermined intervals so as to increase a surface area, in order to improve heat transfer efficiency with air.

The substrate 310 is larger than the insertion hole 281 of the cover member 280, supported by the inner surface of the cover member 280, and is in contact with one side surface of the thermoelectric device 400 inserted through the insertion hole 281, thereby being cooled or heated by the thermoelectric device 400.

The heat exchange fin 320 is disposed among the first circulation flow path 250, the second circulation flow path 260, and the communication flow path 230, and exchanges heat with air flowing in through the first circulation flow path 250 and the second circulation flow path 260. The air heat-exchanged with the heat exchange fins 320 in this way is re-introduced into the communication flow path 230 by the operation of the air blowing part 500.

The blowing part 500 is composed of a blowing fan, is disposed in front of the heat exchange fins 320, circulates air so that the air having flowed in through the first and second circulation flow paths 250 and 260 and having heat exchanged with the heat exchange fins 320 flows in through the communication flow path 230 again to the first and second insertion parts 210 and 220, and thus heat transfer efficiency can be further improved.

with this configuration, when the air blowing unit 500 is operated, air flows into the first insertion unit 210 and the second insertion unit 220 through the communication channel 230, and the air flowing into the first insertion unit 210 and the second insertion unit 220 flows on the outer circumferential surface of a cup (not shown) to perform heat exchange, and then flows into the first circulation channel 250 and the second circulation channel 260 through the first through hole 211 and the second through hole 221, and then re-exchanges heat with the heat exchange unit 300, and then flows into the communication channel 230 through the air blowing unit 500.

Accordingly, the two cups inserted into the first and second insertion parts 210 and 220, respectively, can be all insulated using one thermoelectric device 400 and heat exchange part 300.

fig. 8 and 9 are a perspective view and a separated perspective view schematically showing a heat radiating unit according to an embodiment provided in the cup holder for a vehicle.

Referring to fig. 8 and 9, the heat radiating unit 600 is configured to cool the thermoelectric device 400 by contacting the other side surface of the thermoelectric device 400.

More specifically, the heat dissipating unit 600 includes: a heat pipe 610 contacting the other side surface of the thermoelectric device 400 and receiving heat of the thermoelectric device 400; a heat sink 620 coupled to the holder 200 to closely fix the heat pipe 610 to the thermoelectric device 400; and a heat sink 630 connected to the heat pipe 610 and having a plurality of heat radiating fins for radiating heat to the outside.

With this configuration, when one side surface of the thermoelectric device 400 is cooled to cool the cup, the other side surface is heated, and thus the heat transfer pipe 610 receives heat generated at the other side surface of the thermoelectric device 400 and then is cooled by convection heat exchange at the heat sink 630, thereby cooling the other side surface of the thermoelectric device 400.

Here, a structure for cooling the heat sink 630 may be provided.

That is, the heat dissipating unit 600 may further include: a housing 640 having an inner portion penetrating therethrough and accommodating the heat sink 630 therein; a cover 650 coupled to an upper side of the heat sink 630 in the housing 640, and having a plurality of communication holes formed therein so as to allow air to flow; and a cooling fan 660 disposed below the heat sink 630 in the housing 640, and configured to generate a flow of air so as to cool the heat sink 630.

Therefore, when the cooling fan 660 is operated, air flows inside the housing 640, and the flowing air exchanges heat with the radiator 630 and then flows to the outside through the communication hole of the cover 650, thereby improving the cooling efficiency of the radiator 630.

Fig. 10 is a perspective view schematically showing a state in which a heat radiation unit according to another embodiment is provided in a cup holder for a vehicle according to an embodiment of the present invention.

referring to fig. 10, a heat dissipating unit 700 of another embodiment is such that a heat sink provided with a plurality of heat dissipating fins is in direct contact with the other side of the thermoelectric device 400.

Although not shown, a cover, and a cooling fan may be further provided to improve the cooling efficiency of the heat sink, as in the heat dissipating unit 600 of the above-described embodiment shown in fig. 8 and 9.

As described above, the present invention is explained by the embodiments and the drawings which are limited thereto, but the present invention is not limited thereto, and it is obvious that various modifications and variations can be made to the present invention by those skilled in the art to which the present invention pertains within the equivalent scope of the technical idea of the present invention and the scope of the claims.
