FIG. 2 is a cross-sectional view of aa ′ of FIG. 1 of a heat steering wheel according to the present invention. FIG.

1 and 2, the heating steering wheel according to the present invention includes a wood portion A, a leather portion B, and a recess portion C.

Wood portion (A) is a portion where the upper pattern is exposed to the outside, and the appearance is beautiful through the pattern layer formed by the pattern by a variety of methods, and the wood portion heating layer 130 is provided to the temperature of the wood portion (A) Can be raised.

The leather part (B) is a part that is wrapped in a separate leather, unlike the wood part (A), and improves the grip feeling when the driver steers, and the leather part (B) also has a leather part heating layer (230). The temperature of B) can be raised.

The recess C is located between the wood part A and the leather part B, and an end portion of the leather 260 is inserted and fixed, and the both sides of the recess C are electrically connected to the leather part B. ), As well as the wood portion (A) to enable uniform heat generation.

Looking at the wood portion (A) first,

The wood portion A is a portion where the upper pattern is exposed to the outside, and the wood portion A increases the temperature of the wood portion A by including the wood portion heat generating layer 130. Here, the wood part A is not limited to a wood pattern as a part that looks beautiful, and may express various patterns such as metal, marble, and hair lines. .

Referring to FIG. 2, as an example of the structure of the wood part A, the wood part A includes a plastic resin layer 110, a wood part heat generating layer 130, and a pattern layer 140 surrounding the hub core H. It may include a wood protective layer 150.

The plastic resin layer 110 is a layer surrounding the hub core (H), and may include at least one of ABS (Acrylonitrile Butadiene Styrene copolymer), PC (PolyCarbonate) resin in consideration of the grip of the wood portion (A). Can be.

The wood part heating layer 130 has a structure surrounding the plastic resin layer 110 and serves to increase the temperature of the wood part A.

The wood portion heat generating layer 130 preferably uses a heat generating paint to release heat.

Conventionally, since the heating coil was directly embedded, it was difficult to form the pattern layer 140 having a beautiful pattern on the top due to the shape of the heating coil, but by forming the heating paint outside the plastic resin layer 110 through coating or the like, It is possible to form the pattern layer 140 having various patterns on the outside of the sub heating layer 130.

In order to form the wood heating layer 130 on the outer side of the plastic resin layer 110, a spray coating method for directly spraying the exothermic paint to the outer side of the plastic resin layer 110 and a heating coating printed in a predetermined pattern pad in advance. After being buried in, the pad printing method to be transferred to the outside of the plastic resin layer 110 can be used.

3 is a view illustrating a state in which a wood heat generating layer is formed by a spray coating method as one embodiment of a wood heat generating layer according to the present invention, and FIG. 4 is a pad printing as another embodiment of the wood heat generating layer according to the present invention. It shows the state in which the wood heating layer is formed by the method.

In particular, when the pad printing method is used, the wood portion heat generating layer 130 can be transferred in a predetermined pattern, so that the pattern of the wood portion heating layer 130 appears in parallel along the circumferential direction of the rim as shown in FIG. 4. Can print.

By printing the pattern of the wood portion heat generating layer 130 in parallel so that a portion of the wood portion heat generating layer 130 is scratched, the amount of current flowing through the wood portion heating layer 130 is different. Since it is dispersed in a pattern, the upper limit of the temperature temporarily rising to the portion where the scratch is generated can be lowered, so that an image or the like caused by the heat generating steering wheel can be prevented.

The pattern layer 140 may be formed by applying the coating material having excellent heat resistance to the outside of the wood heat generating layer 130, and transferring the transfer film to the outer circumferential surface of the wood heat generating layer 130 by using a hydrostatic transfer method. It can also form by making it.

It is possible to express a beautiful appearance by printing patterns such as wood, metal, marble and hair line through the hydraulic transfer method.

The wood protection layer 150 is formed outside the pattern layer 140 to protect the pattern layer 140.

Wood portion protective layer 150 is formed of a transparent material to make the pattern of the pattern layer 140 easily visible to the outside, such a transparent material such as PU resin, ester resin, acrylic resin, fluorine resin, CPP and other Transparent synthetic resins may be used.

That is, the pattern layer 140 that can express a variety of colors and patterns is formed on the outside of the wood portion heat-generating layer 130 coated with a heating paint as described above to increase the appearance and at the same time heat generation is possible, the pattern The layer 140 may be protected by the wood protection layer 150 to prevent damage such as scratches and the like on the pattern layer 140 and increase durability.

Next, looking at the leather (B),

Leather portion (B) is a portion wrapped in a separate leather 260 to improve the grip of the driver when steering, and has a leather portion heat generating layer 230 can increase the temperature of the leather portion (B).

Referring to FIG. 2, as an embodiment of the structure of the leather part B, the leather part B includes a foamable resin layer 210, a leather part heating layer 230, and a leather part protective layer surrounding the hub core H. 250 and leather 260.

The foamable resin layer 210 has a structure surrounding the hub core (H), and is made of a foamable resin. The foamable resin layer 210 may be made of a foamable polyurethane resin in consideration of the grip feeling of the leather part B and the like.

Leather portion heating layer 230 has a structure surrounding the foamable resin layer 210, and serves to increase the temperature of the leather (B).

The leather heating layer 230 may use a coil type for directly embedding the heating coil and a coating type for coating the heating paint to emit heat.

When using a coil type to embed the heating coil, a welding method may be used to electrically connect the leather part heating layer 230 and the conductive member disposed in the recess C.

In the case of using the coating type for coating the exothermic paint, since the leather part heating layer 230 is coated on a part or all of the conductive member disposed in the recess C, the recess C and the leather B are Electrical connection by the coating.

In the case of the coating type, after the spray coating method for directly spraying the exothermic paint on the outside of the foamable resin layer 210 and the exothermic paint printed in a predetermined pattern on the pad, the pad printing is transferred to the outside of the foamable resin layer 210. Can be used.

The leather protection layer 250 is formed outside the leather heating layer 230 to protect the leather heating layer 230. The leather protection layer 250 may be selectively included in consideration of properties, materials, and the like of the leather heating layer 230.

Leather 260 wraps the protective part 250 of the leather part, and is a part in direct contact with the driver's hand to improve the grip feeling due to the touch of the leather 260, increase the frictional force with the hand to slip the hand during steering. To prevent it.

That is, the leather portion heating layer 230 coated with the exothermic coating as described above is a structure that is wrapped by the leather 260, and improves the grip by the touch of the surface of the leather 260 and of the leather portion heating layer 230 The heat can provide a comfortable driving environment, especially during winter driving.

Next, look at the concave portion (C),

The recess C is located between the wood part A and the leather part B, and an end portion of the leather 260 is inserted and fixed, and the both sides of the recess C are electrically connected to the leather part B. ), As well as the wood portion (A) allows uniform heat generation

Referring to FIG. 2, the recess C includes the resin layer 310 and the conductive member 320.

The resin layer 310 surrounds the hub core H, and has a fixed groove having an outer diameter smaller than that of the plastic resin layer 110 of the wood part A and the foamable resin layer 210 of the leather part B. 311 is formed.

When the leather part (B) is wrapped in the leather 260, the fixing groove 311 pushes the end of the leather 260 to prevent the lifting of the leather to fix the leather 260 and at the same time finish Formed part.

The fixing groove 311 has a shape corresponding to the conductive member to be described later. Since the conductive member is previously inserted into the mold for injection molding, injection molding is performed in the state where the conductive member is inserted, and the fixing groove is molded to have a shape corresponding to the conductive member.

The resin layer 310 may be formed of a plastic resin and / or a foamable resin.

The resin layer 310 is injection molded the plastic resin layer 110 in the wood portion (A), and then in the process of injection molding the foamable resin layer 210 in the leather portion (B) plastic resin layer 110 and the foamability It may be formed between the resin layer 210. However, the formation of the resin layer 310 is not limited thereto, and may be formed even after the injection molding of the expandable resin layer 210 and the injection molding of the plastic resin layer 110.

The conductive member 320 is coupled to the fixing groove of the resin layer 310, and electrically connects the wood heat generating layer 130 and the leather heat generating layer 230.

When the conductive member 320 is coupled to the fixing groove 311, since the conductive member 320, which is a preformed structure, is coupled, the thickness of the conductive member 320 may be uniformly preformed, resulting in uneven thickness. Local overheating or short circuit can be prevented.

The conductive member 320 preferably uses a metal material. Thereafter, despite the strong pressure acting on the conductive member 320 when wrapped in the leather 260, the conductive member 320 may prevent a problem that the surface is cracked or scratched by using a metal material. Nickel or copper is generally used as the metal material used as the conductive member 320, but is not necessarily limited thereto.

In addition, the conductive member 320 has a structure in which the top is open. By having an open top structure, the end of the leather 260 can be inserted therein. Here, the upper portion refers to a portion exposed to the outside when the conductive member 320 is combined with the resin layer 310.

The conductive member 320 has an open top structure and may have various shapes.

As an embodiment of various shapes of the conductive member 320, the opening may have a 'c' shape facing upward. The conductive member 320 having a 'c' shape has a horizontal portion 321 in contact with the inner surface of the fixing groove 311 and a vertical portion 323 in contact with the side surface of the fixing groove 311. The vertical portion 323 may have an extension portion 325 extending in a horizontal direction on an upper portion thereof to increase an area in contact with the heating layers 130 and 230, thereby improving electrical connection with the heating layers 130 and 230.

5 is a sectional view showing a recessed part according to another exemplary embodiment of the present invention.

As another embodiment of various shapes of the conductive member 320, the locking step 327 may be formed on the side as shown in FIG. 5. Since the locking step 327 is formed at the side portion, the separation of the conductive member 320 from the resin layer 310 can be prevented. In FIG. 5, it is illustrated that the locking step 327 is formed at the lower side of the conductive member 320. However, if the locking step 327 is formed at the side, the location of the locking step 327 is not limited.

As the locking step 327 formed at the side of the conductive member 320 is coupled to the resin layer 310, the conductive member 320 may be prevented from being separated from the resin layer 310 due to a physical locking. .

In order to allow the conductive member 320 having various shapes to be coupled to the resin layer 310, the conductive member 320 may be disposed by various methods. In one embodiment, the conductive member 320 may be formed by insert injection. Can be deployed.

After arranging the conductive member 320 preformed in various shapes in a mold, the resin layer 310 may be injection molded, thereby bonding to the resin layer 310.

In addition, the metal material used as the conductive member 320 has high conductivity, and preferably, a material having a small resistance. As the metal material is high in conductivity, both ends of the concave portion C are electrically connected, but the resistance is small, thereby preventing the concave portion C from being overheated. Nickel and copper are generally used as the metal material used as the conductive member, but are not particularly limited thereto.

Although not shown in the drawings, the recess C may further include a recess heating layer and a recess protective layer on the outer circumferential surface of the conductive member 320.

By including the concave portion heating layer, the concave portion C can be heated while assisting the electrical connection between the wood portion A and the leather portion B. FIG. In addition, the surface of the recess C may be protected from external pressure or the like when the leather 260 is fixed by including the recess protective layer.

Conductive member disposition step (S110) is a step of placing the preformed conductive member 320 in the mold before the injection operation. At this time, the conductive member 320 may have a variety of shapes as the upper structure is open.

The conductive member coupling step (S130) closes the mold on which the conductive member 320 is disposed and supplies resin to form a plastic resin layer 110 on the outer circumferential surface of the hub core of the wood portion, and expand the foamable resin layer 210 on the outer circumferential surface of the leather portion. By forming, the conductive member 320 is bonded to the resin layer 310 formed between the plastic resin layer 110 and the foamable resin layer 210.
