(15) An electrode carrier 100 according to a preferred embodiment of the present disclosure is applied to an armrest heating device of a vehicle.

(16) The electrode carrier 100 may include electrode parts 200 and a fixing member 110.

(17) More specifically, the electrode parts 200 have polarities different from each other, and are deployed in a length direction of the vehicle.

(18) The fixing member 110 serves to fix the electrode parts 200 to the vehicle.

(19) It may be preferable that the fixing member 110 fixes the electrode parts 200 to an armrest core part 401 of the vehicle.

(20) More specifically, on a door trim 500 of the vehicle, the armrest core part 401, an armrest cushion part 402, and an armrest skin part 403 may be provided as illustrated in FIG. 3.

(21) The electrode carrier 100 is fixed to the armrest core part 401.

(23) The armrest skin part 403 covers an upper portion of the armrest cushion part 402.

(24) Meanwhile, a CNT composite material part 300 is formed to surround the electrode carrier 100.

(25) It may be preferable that the electrode carrier 100 is provided on a position on which an arm of a passenger is put on the door trim 500.

(26) In this case, it may be preferable that the thickness of the CNT composite material part 300 is 1.0 T, and the thickness of the armrest cushion part 402 is 5 T.

(27) Further, it may be preferable that the armrest skin part 403 has a thickness of 0.5 T.

(28) Meanwhile, it may be preferable that the thickness of each of the first electrode part 201 and the second electrode part 202 is 0.5 T.

(29) The electrode parts 200 may include a first electrode part 201 and a second electrode part 202 formed in a straight line along a length direction of the vehicle.

(30) It may be preferable that the fixing member 110 fixes the first electrode part 201 and the second electrode part 202 to be in parallel to each other and to be spaced apart from each other at a specific distance.

(31) More specifically, the fixing member 110 may include a plurality of lateral fixing members directed toward an indoor direction of the vehicle and configured to support the first electrode part 201 and the second electrode part 202 in the shortest distance between the first electrode part 201 and the second electrode part 202.

(32) Further, it may be preferable that the fixing member 110 may include a longitudinal fixing member directed toward the length direction of the vehicle and configured to connect among the plurality of lateral fixing members.

(33) Here, it may be understood that the term “longitudinal” indicates the length direction of the vehicle, and the term “lateral” indicates the indoor direction that is vertical to the length direction of the vehicle.

(34) In this case, the lateral fixing members may include a first fixing member 111, a second fixing member 112, and a third fixing member 113.

(35) More specifically, the first fixing member 111 may connect one end of the first electrode part 201 to one end of the second electrode part 202.

(36) The second fixing member 112 may connect the other end of the first electrode part 201 to the other end of the second electrode part 202.

(37) The third fixing member 113 may connect a center of the first electrode part 201 to a center of the second electrode part 202.

(38) Further, the longitudinal fixing member may include at least one of a fourth fixing member 114 and a fifth fixing member 115.

(39) In other words, it may be preferable that the longitudinal fixing member includes at least one of the fourth fixing member 114 configured to connect between the first fixing member 111 and the third fixing member 113 and the fifth fixing member 115 configured to connect between the second fixing member 112 and the third fixing member 113.

(40) In this case, the fourth fixing member 114 or the fifth fixing member 115 may connect between the center parts of the lateral fixing members.

(41) Meanwhile, it may be preferable that the first fixing member 111, the fourth fixing member 114, and the third fixing member 113 are “H”-shaped as a whole.

(42) Further, it may be preferable that the second fixing member 112, the fifth fixing member 115, and the third fixing member 113 are “H”-shaped as a whole.

(43) Meanwhile, it may be preferable that the electrode parts 200 are fixed through the lateral fixing members.

(44) It may be preferable that end parts of the electrode parts 200 project by a specific length from the first fixing member 111.

(45) The end parts of the electrode parts 200 project by the specific length from the first fixing member 111 and thus may be easily connected to a power supply part (not illustrated).

(46) However, because the end parts of the electrode parts 200 do not excessively project from the first fixing member 111, the damage to the electrode parts can be suppressed.

(47) Meanwhile, it may be preferable that the lateral fixing member includes an upper fixing part 120 formed to project upward from an upper surface of the lateral fixing member and fixed to the armrest core part 401.

(48) In one of the embodiments, it may be preferable that the upper fixing part 120 has a conical shape, and a diameter of the upper fixing part 120 is increased toward the upper part of the upper fixing part 120.

(49) Accordingly, the upper fixing part 120 can be suppressed from descending due to the gravity when the upper fixing part 120 is fixed to the armrest core part 401, and thus the stiffness and durability can be secured.

(50) Further, it may be preferable that the upper fixing part 120 is formed in the center of the upper surface of the lateral fixing member.

(51) Meanwhile, it may be preferable that the lateral fixing member includes a lower fixing part 130 formed to project downward from a lower surface of the lateral fixing member and fixed to the armrest core part 401.

(52) Further, in one of the embodiments, the lower fixing part 130 has a conical shape, and it may be preferable that a diameter of the lower fixing part 130 is increased toward the lower part of the lower fixing part 130.

(53) Accordingly, a fine displacement of the upper fixing part 120 in an upward direction can be suppressed when the upper fixing part 120 is fixed to the armrest core part 401, and thus the stiffness and durability can be secured.

(54) Meanwhile, it may be preferable that the lower fixing part 130 is formed in the center of the lower surface of the lateral fixing member.

(55) In one of the embodiments, it may be preferable that the thickness of the upper fixing part 120 is greater than that of the lower fixing part 130.

(56) This is because the fine displacement amount of the electrode carrier 100 in a downward direction by the gravity may be larger than the fine displacement amount of the electrode carrier 100 in an upward direction by the gravity, and by forming the thickness of the upper fixing part 120 to be greater than that of the lower fixing part 130, it is possible to minimize the movement due to the difference between the fine displacement amounts.

(57) Meanwhile, the distance between the first fixing member 111 and the third fixing member 113 may be equal to the distance between the third fixing member 113 and the second fixing member 112.

(58) In other words, the fourth fixing member 114 and the fifth fixing member 115 may have the same length.

(59) Further, the first fixing member 111, the second fixing member 112, and the third fixing member 113 may be formed to have the same shape.

(60) Meanwhile, it may be preferable that the electrode carrier 100 according to a preferred embodiment of the present disclosure is formed of a thermoplastic material.

(61) Further, the CNT composite material may be formed to surround the fixing member 110 and to have a surface area, and enables the electrode parts 200 to uniformly generate heat when being electrified.

(62) The CNT composite material is a component made of CNT mixtures, provided with the electrodes, and configured to self-generate heat when being electrified.

(63) The CNT composite material generates heat when being electrified through the electrode parts, and the principle thereof is as follows.

(64) A CNT heating element is obtained through combination of the CNT, which is a conductive additive, and a high molecular compound, and has the property of a conductor.

(65) According to the principle, if electricity is applied to the CNT heating element, heat is generated in the process of electron movements.

(66) While the present disclosure has been described with reference to the exemplified drawings, it will be apparent to those of ordinary skill in the art that the present disclosure is not limited to the described embodiments, and various changes and modifications may be made without departing from the spirit and scope of the present disclosure.
