1 is a perspective view of a sunroof sealing assembly 1 according to one embodiment.

Referring to Fig. 1, a sealing assembly 1 for a sunroof according to an embodiment can be used in a sunroof provided in an automobile C. Fig.

For example, the car C may be provided with an opening O that opens at least a part of the roof of the car C. [ The sunroof may include a sunroof glass (G) capable of selectively opening and closing the opening (O) and being formed to correspond to the size of the opening (O) to close the opening (O). In this case, the sealing assembly 1 for the sunroof can seal the space between the sunroof glass G and the opening O when the sunroof closes the opening O. [

Therefore, the sealing assembly 1 for the sunroof can be provided so as to surround the circumference of the sunroof glass G. Hereinafter, the sunroof sealing assembly 1 will be described in detail. For convenience of explanation, a configuration in which the sunroof glass selectively opens and closes the opening O formed in the automobile C by a driving means not shown is known to those skilled in the art, so a detailed description thereof will be omitted .

Fig. 2 is an exploded perspective view of a sealing assembly 1 for a sunroof according to an embodiment, Fig. 3 is a partial top view for showing a connection between a reinforcing unit and a supporting unit, Fig. 4 is a cross- Fig. 5 is a cross-sectional view taken along line V-V in Fig. 3; Fig.

The sealing assembly 1 for the sunroof may comprise a support unit 10, a rigid unit and a reinforcement unit 30. [

The supporting unit 10 supports the bottom surface of the sunroof glass G along the circumference of the sunroof glass G and the sealing unit 20 is connected to one side of the supporting unit 10 to form a sunroof glass G, It is possible to seal the space between the opening O and the sunroof glass G when the opening O is closed and the reinforcing unit 30 is connected to the other side of the supporting unit 10, 10 and the sealing unit 20 can be reinforced. In this case, the support unit 10 may be overmolded and injected onto the outer surface of the reinforcing unit 30 to be integrally formed.

2, the support unit 10 is overmolded and injection-molded so as to cover at least a part of the outer surface of the reinforcement unit 30, so that the support unit 10 can be integrally formed .

In this case, the reinforcing unit 30 and the supporting unit 10 are formed of different kinds of materials, and can be formed to have a single structure by being heterogeneously injection-molded by an overmolding injection molding method. Specifically, the support unit 10 formed of a plastic material is overmolded and injection-molded into the reinforcing unit 30 made of a metal material, so that the additional unit 30 for connection between the reinforcing unit 30 and the supporting unit 10 The process can be excluded.

For example, the supporting unit 10 may be formed to include polypropylene (PP) and glass fiber (GF), and the reinforcing unit 30 may include steel.

The support unit 10 may be provided so as to be connected along the circumference of the sunroof glass G. [ In this case, the support unit 10 may be provided to form a closed loop having a shape corresponding to the rim of the sunroof glass G.

The supporting unit 10 includes a first connecting portion 11 connected to the sealing unit 20, a first supporting portion 12 supporting the sunroof glass G and a second supporting portion 13 supporting the reinforcing unit 30 ).

The first connection part 11 may be formed to protrude toward the sealing unit 20. [ The first connection part 11 may be coupled to the sealing unit 20 to connect the supporting unit 10 and the sealing unit 20. For example, the first connection portion 11 may be inserted into the sealing unit 20. [

The first connection portion 11 may include a first connection protrusion 111 and a second connection protrusion 112 formed at the end of the first connection portion 11, respectively. The first connection protrusion 111 may protrude from the upper portion of the first connection portion 11 and the second connection protrusion 112 may protrude from the lower portion of the first connection portion 11. [

The first support portion 12 can support the bottom surface of the sunroof glass G. [ The first support part 12 may be formed to form a closed loop along the circumference of the sunroof glass G. [ In other words, the first support portion 12 is provided in a shape corresponding to the rim of the sunroof glass G, and can support a part of the bottom surface of the sunroof glass G.

The second supporting part 13 may be formed to extend toward the center of the front loop glass G like the first supporting part 12. [ The second support portion is spaced apart from the first support portion 12 by a predetermined distance, thereby providing a space in which the support unit 10 can be positioned. The support unit 10 is disposed in the space between the first support portion 12 and the second support portion 13 and is in contact with the lower surface of the first support portion 12 and the upper surface of the second support portion 13 .

The supporting unit 10 may include an upper fixing protrusion 113 protruding from the upper portion of the first connecting portion 11. [ The upper fixing protrusion 113 may be formed at a position where the sealing unit 20 and the sunroof glass G are in contact with each other.

The upper fixing protrusion 113 may protrude along the side surface of the sunroof glass G supported by the first connecting portion 11. [ In this case, the upper fixing protrusion 113 can prevent the sunroof glass G from moving in the first supporting portion 12. [

The support unit 10 may include a lower projection protruding downward. The lower protrusions may be formed at plural intervals along the periphery of the support unit 10 at a predetermined interval. The lower projection may be formed on the lower side of the supporting unit, for example, on the lower side of the second supporting portion 13. [ In this case, the lower protrusion can reduce the noise due to the air flow while the sunroof glass G is tilted so as to open the opening (O) by the operation of the sunroof. Specifically, when the sunroof glass G is tilted, the support unit 10 is also tilted upward in the opening (O). The lower projection formed on the lower side of the support unit 10 interferes with the flow of the air flowing through the open space and can reduce the noise caused by the air flow.

The sealing unit 20 may be connected to be engaged with the supporting unit 10. [ The sealing unit 20 is connected to the supporting unit 10 so as to be in contact with the sunroof glass G supported by the first supporting part 12 and is connected to the sunroof glass when the sunroof closes the opening O. [ G) and the opening (O).

The sealing unit 20 includes a first sealing fixing part 21 extending to cover an upper portion of the first connection part 11, a second sealing fixing part 22 extending to cover a lower portion of the first connection part 11, And a sealing portion 23 which extends in the opening (O) direction and seals between the opening O and the sunroof glass G. [

The first seal fixing part 21 and the second seal fixing part 22 are spaced apart from each other so that a space can be formed so that the first connection part 11 of the support unit 10 can be inserted. Hereinafter, for convenience of explanation, the first sealing fixing part 21 and the second sealing fixing part 22 may collectively be referred to as a " sealing fixing part ".

The first sealing sealing portion 211 and the second sealing sealing portion may be formed in the first sealing fixing portion 21 and the second sealing fixing portion 22. Specifically, the first sealing insertion groove 211 may be formed on the lower surface of the first seal fixing part 21 so that the first connection protrusion 111 formed on the first connection part 11 can be inserted. Likewise, the second sealing insertion groove may be formed on the upper surface of the second sealing fixing portion 22 so that the second connection projection 112 can be inserted.

The first sealing fixing portion 21 extends along the upper surface of the first connection portion 11 of the supporting unit 10 and can contact the side surface of the sunroof glass G disposed on the first supporting surface. In this case, the first sealing fixing part 21 can have a smooth flat shape with respect to the exposed surface of the sunroof glass (G). For example, the bottom surface of the first sealing fixing portion 21 is in close contact with the top surface of the first connection portion 11, and the top surface of the first sealing fixing portion 21 is in contact with the top surface of the sunroof glass G It can be connected to a flat surface with no steps.

The second sealing fixing portion 22 may extend along the lower surface of the first connection portion 11 of the support unit 10. [ In this case, the end of the second seal fixing part 22 is bent upward, so that the first connection part 11 can be firmly supported.

The sealing portion 23 extends in the opening (O) direction from the sealing fixing portion and may have a sealing space 24 therein. Therefore, the sealing part 23 can be pressed by the sealing space 24, and when the sunroof glass G closes the opening O, the sealing part 23 is closed between the opening O and the sunroof glass G Can be sealed.

The sealing unit 20 may be formed of an elastic material. For example, the sealing unit 20 may be formed of a material such as rubber. Therefore, the sealing unit 20 can effectively seal the space between the sunroof glass G and the opening O by being elastically compressed when the sunroof glass G closes the opening 0.

In this case, the sealing portion 23 may be formed in a hollow semicircular shape with the sealing space 24 therebetween. For example, the cross-sectional shape of the sealing portion 23 and the sealing space 24 may have a shape as shown in Fig. However, this is merely an example, and the shapes of the sealing portion 23 and the sealing space 24 are not limited thereto.

The reinforcing unit is overmolded with the supporting unit 10 so that the sealing unit 20 connected to the supporting unit 10 is fixed to the front glass glass G so as to reinforce the strength of the front glass glass G . The reinforcing unit may be formed of a rigid material having rigidity. For example, the reinforcement unit may include steel.

The reinforcing unit is composed of a reinforcement inserting portion arranged in the space between the first supporting portion 12 and the second supporting portion 13 of the supporting unit 10 and a reinforcing inserting portion extending from the reinforcing inserting portion 31 to the lower portion of the sunroof glass G And may include a reinforcing support portion 32.

Since the support unit 10 is overmoulded and injection-molded along the outer surface of the reinforcement insertion portion 31, the reinforcement insertion portion 31 has a shape that is inserted between the first support portion 12 and the second support portion 13 . In this case, since the reinforcement insertion portion 31 and the support unit 10 are integrally formed and connected, the first support portion 12 and the second support portion 13 are in intimate contact with the reinforcement insertion portion 31, No connection or assembly process is required.

The reinforcement insertion portion 31 may include a reinforcement insertion hole 311 into which the overmolded and projected support unit can be inserted. For example, the reinforcing insertion hole may be formed by vertically penetrating the reinforcing insertion portion, as shown in Fig. Although the shape of the cross section of the reinforcing insertion hole is shown as circular in the figure, this is merely an example, and the shape of the reinforcing insertion hole is not limited thereto, and it is also possible to have a rectangular or elliptical cross section.

As shown in Fig. 4, the reinforcing insertion holes may be formed so as to be spaced a predetermined distance along the circumference of the reinforcing unit. In this case, the support unit can be connected through the reinforcing insertion hole while being overmolded so as to surround the periphery of the reinforcing unit. Therefore, after the support unit is over-molded and injected into the reinforcement unit, it is possible to prevent the support unit from being detached from the reinforcement unit.

In other words, as shown in Fig. 3, a cross section to which the support unit and the reinforcement unit are connected is shown at a position where the reinforcement insertion hole is not formed, and at the position where the reinforcement insertion hole is formed, As shown in FIG.

The reinforcement supporting portion 32 is formed so as to extend from the reinforcement insertion portion 31 so as to extend along the lower portion of the sunroof glass G. In this case, the adhesive material 33 is applied to the space between the reinforcing supporting portion 32 and the bottom surface of the front loop glass G, so that the front loop glass G and the reinforcing supporting portion 32 can be bonded.

Although not shown in the drawing, one side of the reinforcing support portion 32 may extend so as to be bent toward the lower side. In this case, the end portion of the reinforcing support portion is upwardly bent so as to face the bottom surface of the front loop glass, and can adhere to the bottom surface of the front loop glass to support the front loop glass. In other words, the cross section of the reinforcing support portion may be formed such that one side thereof protrudes in the downward direction of the sunroof glass. In this case, the inner structure of the opening can be prevented from being exposed to the outside through the protruding portion of the reinforcing support portion on the basis of the state in which the sunroof glass is tilted so as to open the opening.

The reinforcement unit 30 is wrapped by the first support portion 12 and the second support portion 13 of the support unit 10 so that corrosion due to moisture that may flow between the opening O and the moisture can be prevented . Specifically, the moisture introduced into the gap between the sunroof glass G and the sealing unit 20 through the support unit 10 can prevent the reinforcing unit 30 from corroding, and the opening O and the sealing unit 20 Is lowered downward by gravity, it is possible to prevent the reinforcing unit 30 from being corroded.

Hereinafter, a method of assembling the sunroof sealing assembly 1 will be described in detail with reference to FIGS. 2 to 5. FIG. In describing the assembly method of the sealing assembly 1 for the sunroof, the description overlapping with the above description will be omitted.

The supporting unit 10 may be overmolded and injection-molded into the reinforcing unit 30 to be integrally formed. The support unit 10 can be installed to support the rim of the sunroof glass G. [ For example, the first support portion 12 supports a part of the bottom surface of the sunroof glass G along the rim of the sunroof glass G, and the first support portion 12 is supported by the upper fixing projections 113, The position of the sunroof glass G can be fixed.

In this case, since the reinforcing unit 30 is formed integrally with the supporting unit 10, the reinforcing supporting portion 32 is positioned below the sunroof glass G. [ An adhesive member 33 is provided in the space between the sunroof glass G and the reinforcing support portion 32 and can be adhered to the lower surface of the sunroof glass G and the upper surface of the reinforcing support portion 32. Therefore, the reinforcing unit 30 can be brought into close contact so as to reinforce the rigidity of the sunroof glass (G).

The sealing unit 20 can be engaged with the support unit 10. The first connecting portion 11 of the supporting unit 10 can be inserted into the space between the first sealing fixing portion 21 and the second sealing fixing portion 22 of the sealing unit 20. [ In this case, the first connection protrusion 111 formed at the end of the first connection part 11 is inserted into the first sealing insertion groove 211 formed in the first sealing fixing part 21, and the second connection protrusion 112 May be inserted into the second sealing insertion groove 212 formed in the second sealing fixing portion 22. [ In other words, by engaging the first connecting projection 111 with the first sealing insertion groove 211 and engaging the second connecting projection 112 with the second sealing insertion groove 212, the supporting unit 10 and the sealing The unit 20 can be firmly assembled.

In this case, since the sealing unit 20 and the supporting unit 10 are connected by the coupling structure, a separate bonding member 33 for bonding the sealing unit 20 and the supporting unit 10 is not required.

The sealing unit 20 is formed of an elastic material so that the first sealing fixing part 21 is tightly fitted to the edge of the front glass G so that the sealing unit 20 is interposed between the sealing unit 20 and the front loop glass G It is possible to seal the space of the battery. In this case, the upper surface of the first seal fixing part 21 and the open surface of the sunroof glass G can be connected without a step.

The assembled sunroof assembly 1 thus assembled is installed at the opening O formed in the vehicle as shown in Fig. 1, and can selectively open the opening O according to the operation of the sunroof have.

The sealing assembly 1 for a sunroof according to the embodiment described above is constructed by overmolding injection molding of a plastic supporting unit 10 into a reinforcing unit 30 made of a metal material so that the supporting unit 10, The process of connecting the reinforcement unit 30 may be omitted. Therefore, the manpower required for assembling the supporting unit 10 and the reinforcing unit 30 and the production time can be reduced.

In addition, since the reinforcing unit 30 and the supporting unit 10 are integrally formed, corrosion of the reinforcing unit 30 due to moisture can be prevented, and a large space is required for assembling the sunroof sealing assembly 1 It does not.

Hereinafter, a method of manufacturing the sunroof sealing assembly 1 according to the embodiment will be described.

Fig. 6 is a flowchart of a manufacturing method of the sealing assembly 1 for sunroof according to the embodiment. Fig. 7 is a flowchart of steps for manufacturing the supporting unit 10 and the reinforcing unit 30. Fig.

6, the manufacturing method of the sealing assembly 1 for a sunroof includes the steps of manufacturing the reinforcing unit 30 (S210), overmolding and injecting the supporting unit 10 into the reinforcing unit 30 Step S230 of connecting the front-end glass G to the supporting unit 10 and S240 joining the sealing unit 20 to the supporting unit 10, as shown in FIG.

Step S210 is able to manufacture the reinforcing unit 30. The reinforcing unit 30 may be formed in the form of a frame connected along the circumference of the sunroof glass G. [ In this case, the size and shape of the reinforcing unit 30 can be changed according to the shape and size of the opening O and the sunroof glass G.

The reinforcing unit 30 may be formed of a rigid rigid material. For example, the reinforcing unit may be made of a metal material including steel.

In step S220, the support unit 10 may be overmolded and injection-molded on the reinforcement unit 30 so as to surround the outer side of the reinforcement unit 30 along the periphery of the manufactured reinforcement unit 30. [

Step S220 includes a step of inserting the manufactured reinforcing unit 30 into the mold S221, a step S222 of overmolding the supporting unit 10 into the reinforcing unit 30 by injecting the material into the mold, And removing the supporting unit 10 and the reinforcing unit 30 from the mold (S223).

In step S221, the reinforcing unit 30 can be inserted into the mold. In this case, various methods can be used for accurate positioning of the reinforcing unit 30 in the mold. For example, the reference hole may be set in the reinforcing unit 30 to adjust the exact position of the reinforcing unit 30. [

In step S222, the support unit 10 can be manufactured by injecting the material into the mold. In this case, the material of the support unit 10 may be plastic. For example, the support unit 10 may include a material mixed with polypropylene (PP) and GF (GRASS FIBER). More specifically, as the material of the supporting unit 10, a material obtained by mixing 45% of GF with polypropylene may be used. However, the material of the support unit 10 is not limited thereto, and it is obvious that it is natural to replace it with other materials.

The shape of the support unit 10 can be changed depending on the shape of the mold. For example, the mold may be provided to produce the shape of the supporting unit 10 required for the shape and size of the sealing unit 20 and the reinforcing unit 30 combined with the supporting unit 10. [

 The process of connecting the supporting unit 10 and the reinforcing unit 30 can be performed simultaneously with the process of manufacturing the supporting unit 10 by injecting the material into the mold by overmolding injection molding the supporting unit 10 . In other words, although the supporting unit 10 and the reinforcing unit 30 are made of different kinds of materials, the combining process with the reinforcing unit 30 through the manufacture of the supporting unit 10 and the overmolding injection molding is performed simultaneously The supporting unit 10 and the reinforcing unit 30 can be integrally formed without a separate connecting step. Therefore, a separate process of joining the manufactured supporting unit 10 and the reinforcing unit 30 can be omitted.

In step S223, the support unit 10 that has been manufactured can be taken out of the mold. In this case, the supporting unit 10 and the reinforcing unit 30 can be taken out from the mold in a state in which they are integrally joined. Hereinafter, for convenience of explanation, the support unit 10 and the reinforcement unit 30 are referred to as an overmoulding unit.

In step S230, the front roof glass G can be connected to the completed over-molding unit.

Since the over molding unit is manufactured in a shape corresponding to the sunroof glass G, the outer surface of the sunroof glass G can be seated on one side of the support unit 10. In this case, an adhesive member (glass sealant) is applied to the contact surfaces of the over-molding unit and the sunroof glass G, and the over molding unit and the sunroof glass G can be bonded.

Step S240 may couple the manufactured sealing unit 20 to the overmolding unit. Specifically, the sealing unit may be coupled to one side of the supporting unit 10 so as to be in contact with the sunroof glass G. In this case, the sealing unit 20 can be manufactured in a shape that wraps around the space between the opening (O) and the sunroof glass (G).

A hollow sealing space may be formed inside the sealing unit 20 so that the sealing unit 20 can be pressed. In this case, the sealing unit 20 can be formed of a stretchable elastic material. The sealing unit 20 can be manufactured in a shape corresponding to the shape of the supporting unit 10 so as to be assembled with the supporting unit 10. [ Thus, the sealing unit 20 can be manufactured in the form of a frame extending along the outer surface of the support unit 10. [
