Description

Technical Field

[0001] This disclosure relates to a vehicle grille. Background Technology

[0002] The statements in this section provide only background information in relation to this disclosure and may not constitute prior art.

[0003] Radiator grilles for aerodynamics and engine cooling are located at the front of the vehicle, and grilles are applied to the front design components of the vehicle even when the vehicle is not an internal combustion engine vehicle.

[0004] The grille is a very important factor in the design of the front of a vehicle. Light shines through the grille to enhance its appearance and improve the vehicle's marketability.

[0005] Traditionally, in order to emit light from the grille, lighting devices are installed behind the grille to project light towards the front of the grille; however, we have found that space is needed for the installation of the light source.

[0006] Furthermore, the ease of operation is reduced when manufacturing the grille and connecting the components that form the grille, because the connection should be performed at a different location for each component.

[0007] The above content is only for the purpose of helping to understand the background of this disclosure and does not mean that this disclosure falls within the scope of related technologies known to those skilled in the art. Summary of the Invention

[0008] This disclosure provides a vehicle grille in which lights are turned on and diffused gently from the rear side of the grille, thereby enhancing the grille's appearance. Furthermore, this disclosure provides a vehicle grille in which easy connection is provided when each component forming the vehicle grille is coupled.

[0009] In one embodiment, a vehicle grille is provided, comprising: a grille panel configured to form a grille design; a lens panel disposed on the rear side of the grille panel, formed to have the same shape as a portion or all of the grille panel, and configured to allow light to propagate in the lens panel when light is incident, and to emit a portion of the light to the outside; and a housing including a coupling-providing end disposed on the rear surface of the lens panel, formed to have the same shape as the lens panel, and configured to allow the grille panel to be coupled to the front surface of the lens panel when the lens panel is coupled to the front surface of the housing, wherein the rear surface of the lens panel and the front surface of the housing are coupled on the rear side of the lens panel, and the front surface of the lens panel and the rear surface of the grille panel are coupled on the front side of the lens panel via the coupling-providing end of the housing.

[0010] The laser can be emitted from the front to the rear, allowing the grille panel, lens panel, and housing to be connected, so that the grille panel and housing are fused to the front and rear surfaces of the lens panel.

[0011] In the housing, the frame portion can be connected to the edge of the lens panel, the connection end can extend from the frame portion, and the connection end can be divided into an overlapping section that overlaps with the grille panel on the front side and a non-overlapping section that does not overlap with the grille panel.

[0012] The connection provides an end that extends obliquely from the frame portion to the rear side to form an oblique surface, such that laser light incident from the front side can be reflected by the oblique surface to propagate to the rear surface of the grille panel.

[0013] In the connection end, the non-overlapping sections of the inclined surface on which the laser is incident can undergo surface treatment to increase the reflectivity of the corresponding sections.

[0014] The portion with the grid panel can be bent rearward to form a curved portion in the lens panel. A fusion portion that matches and is disposed on the curved portion of the lens panel can be formed in the grid panel. The connection end of the housing can extend obliquely from the frame portion to the rear side and can be obliquely formed to allow laser light incident from the front side to propagate to the fusion portion of the grid panel.

[0015] The connection provides an end that can extend within the frame portion to have a parabolic curve, thereby forming a curved surface that allows laser light incident from the front to propagate toward the rear side of the grille panel.

[0016] In the connection end, the non-overlapping sections of the curved surface on which the laser is incident can undergo surface treatment to increase the reflectivity of the corresponding sections.

[0017] The portion with the grid panel can be bent rearward to form a curved portion in the lens panel. A fusion portion that matches and is disposed on the curved portion of the lens panel can be formed in the grid panel. The connection end of the housing can extend rearward from the frame portion to have a parabolic curve and can be formed obliquely to allow laser light incident from the front to propagate to the fusion portion of the grid panel.

[0018] The connection end may include: a first reflective end located in a non-overlapping section and configured to extend obliquely in a straight line from the frame portion to the rear side; and a second reflective end located in an overlapping section and configured to extend obliquely in a straight line from the first reflective end to the front side, such that laser light incident from the front side is reflected by the first reflective end and propagates to the second reflective end, and then reflected by the second reflective end and propagates to the rear surface of the grille panel.

[0019] The first and second reflective ends can undergo surface treatment to ensure that the reflectivity of the corresponding sections is high.

[0020] The connection end may include: a first curved end located in a non-overlapping section and configured to extend rearward from the frame portion to have a parabolic curve; and a second curved end located in an overlapping section and configured to extend forward from the first curved end to have a parabolic curve, such that laser light incident from the front can be reflected by the first curved end and propagated to the second curved end, and then reflected by the second curved end and propagated to the rear surface of the grille panel.

[0021] The first and second curved ends can undergo surface treatment so that the reflectivity of the corresponding sections can be high.

[0022] One of the frame sections of the housing can be configured to be longer than the front end, and when the lens panel and the housing are joined, the longer frame section can be joined to the lens panel, and then the other frame sections can be joined to the lens panel.

[0023] According to another embodiment, the vehicle grille includes: a grille panel configured to form a grille design; a lens panel disposed on the rear side of the grille panel, formed to have the same shape as a portion or the entire area of ​​the grille panel, and configured to allow light to propagate in the lens panel when light is incident, and to emit a portion of the light to the outside; and a housing including a connection providing hole disposed on the rear surface of the lens panel, formed to have the same shape as the lens panel, and configured to allow the grille panel to be connected to the front surface of the lens panel when the lens panel is connected to the front surface of the housing, wherein the rear surface of the lens panel and the front surface of the housing are connected on the rear side of the lens panel, and the front surface of the lens panel and the rear surface of the grille panel are connected on the front side of the lens panel through the connection providing hole of the housing.

[0024] The housing can be connected to the rear surface of the lens panel via the peripheral portion of the connection hole, and the grille panel can be configured to face the connection hole of the housing and be connected to the front side of the lens panel.

[0025] In the housing, the peripheral portion of the connection providing the hole can be connected to the rear surface of the lens panel, and the housing and the lens panel can be connected by an extension end that extends from the rear surface of the lens panel toward the peripheral portion of the housing, or from the peripheral portion of the housing toward the rear surface of the lens panel.

[0040] The following description is exemplary in nature only and is not intended to limit this disclosure, its application, or its use. It should be understood that in all the drawings, corresponding reference numerals denote the same or corresponding parts and features.

[0041] Figure 1 This is a schematic diagram showing a vehicle grille according to the present disclosure. Figure 2 It is shown Figure 1 The diagram shows the connection between the grille panel, lens panel, and housing of the vehicle grille. Figure 3 This is a schematic diagram illustrating the first form of this disclosure. Figure 4 This is a schematic diagram illustrating a second form of the present disclosure.

Figure 7 This is a schematic diagram illustrating the fifth form of this disclosure. Figure 8 This is a schematic diagram illustrating the sixth form of this disclosure, and Figure 9 This is a schematic diagram illustrating the frame portion forming the housing of this disclosure. Furthermore, Figure 10 This is a schematic diagram illustrating the connection of the grille panel, lens panel, and housing of a vehicle grille according to another form of this disclosure, and Figure 11 and 12 This is a schematic diagram showing the connection of the grille panel, lens panel and housing of a vehicle grille according to yet another form of the present disclosure.

[0042] like Figure 1 As shown, the vehicle grille according to this disclosure includes: a grille panel 100, which forms a grille design; a lens panel 200 disposed on the rear surface of the grille panel 100, formed in the same shape as a portion or the entire area of ​​the grille panel 100, and configured to allow light to propagate inside the lens panel 200 and to emit a portion of the light to the outside when light is incident; and a housing 300 disposed on the rear surface of the lens panel 200, formed in the same shape as the lens panel 200, and having a connection providing end 310 configured to allow the grille panel 100 to be connected to the front surface of the lens panel 200 when the lens panel 200 is connected to the front surface of the housing 300.

[0043] According to this disclosure, a grille panel 100, a lens panel 200, and a housing 300 are arranged from the front to the rear of the vehicle, and a cover panel 400 forming the front surface portion of the vehicle may also be provided towards the rear of the housing 300. Here, a plurality of holes are formed in the grille panel 100 to allow air to circulate from the front surface portion of the vehicle to its interior and exterior, and the design of the grille panel 100 can be determined based on the plurality of holes. As shown, depending on the desired design, the holes in the grille panel 100 can be formed not only in a rhomboid shape but also in an irregular shape, such as a circle or a polygon.

[0044] Lens panel 200 can be mounted on the rear surface of grille panel 100 and formed to have the same shape as a portion or all of the grille panel 100. Furthermore, lens panel 200 is configured to allow light to pass through and is formed as a light guide, wherein incident light propagates into the light guide and a portion of the incident light is emitted to the outside. Therefore, when lens panel 200 is formed to have the same shape as certain areas of grille panel 100, light is emitted from certain areas of grille panel 100, and when lens panel 200 is formed to have the same shape as the entire area of ​​grille panel 100, light is emitted from the entire area of ​​grille panel 100. This can be determined based on design factors of grille panel 100.

[0045] The housing 300, mounted on the rear surface of the lens panel 200, is formed with the same shape as the lens panel 200. A light source unit 500 for emitting light to the lens panel 200 can be mounted in the housing 300. That is, the housing 300 reflects light propagating toward the rear side of the light emitted from the lens panel 200 to emit the reflected light onto the grid panel 100, thereby improving light efficiency.

[0046] Therefore, according to this disclosure, when the light source unit 500 emits light, the light is emitted through the lens panel 200 disposed on the rear side of the grille panel 100 and propagates to diffuse toward the front side of the grille panel 100, thereby further enhancing the grille panel 100. Furthermore, the housing 300 provides light emission efficiency for the light emitted from the lens panel 200.

[0047] According to this disclosure, to improve the ease of connection between the grille panel 100, lens panel 200, and housing 300, a connection-providing end 310 is formed in the housing 300. The connection-providing end 310 supports the connection between the rear surface of the grille panel 100 and the front surface of the lens panel 200, with the lens panel 200 connected to the front surface of the housing 300 from the rear side, and the rear surface of the grille panel 100 connected to the front surface of the lens panel 200 from the front side via the connection-providing end 310 of the housing 300. In other words, all grille panels 100, lens panels 200, and housing 300 can be processed from the front to the rear, thereby providing operational convenience.

[0048] Specifically, the grille panel 100, lens panel 200, and housing 300 are irradiated with a laser from front to rear, allowing the grille panel 100 and housing 300 to be fused and bonded to the front and rear surfaces of the lens panel 200, respectively. In other words, according to this disclosure, the connection of the grille panel 100, lens panel 200, and housing 300 can be performed using a laser, with the laser emitted from front to rear. As described above, since the laser emission direction is the same when the grille panel 100 and lens panel 200 are connected as it is when the lens panel 200 and housing 300 are connected, the complexity of the manufacturing process is reduced, and manufacturing convenience is improved.

[0049] like Figure 2 As shown, since the lens panel 200 is configured to allow light to pass through, a laser emitted from the front to the rear passes through the lens panel 200 and enters the front surface of the housing 300. Therefore, the rear surface of the lens panel 200 and the front surface of the housing 300 are fused together due to the laser.

[0050] Simultaneously, when the grille panel 100 and the lens panel 200 are connected, the laser should be incident on the rear surface of the grille panel 100. For this purpose, the housing 300 is provided with a connection providing end 310, which switches the propagation path of the laser so that the laser emitted from the front to the rear is reflected by the connection providing end 310 to propagate to the rear surface of the grille panel 100. Therefore, the rear surface of the grille panel 100 and the front surface of the lens panel 200 can be fused together due to the laser.

[0051] As described above, by using a laser emitted from the front to the rear, the grille panel 100 and the housing 300 can be respectively attached to the front and rear surfaces of the lens panel 200. Therefore, since the laser emission direction is the same when the grille panel 100 and the lens panel 200 are attached as it is when the lens panel 200 and the housing 300 are attached, the complexity of the manufacturing process is reduced and the ease of manufacturing is improved.

[0052] like Figure 2 As shown, in the housing 300, the frame portion 320 can be coupled to the edge of the lens panel 200, the coupling providing end 310 extends from the frame portion 320, and the coupling providing end 310 can be divided into an overlapping section A that overlaps the grille panel 100 to the front side and a non-overlapping section B that does not overlap with the grille panel 100.

[0053] As described above, the housing 300 can be formed by a frame portion 320 and a connection-providing end 310, and the frame portion 320 and the connection-providing end 310 are formed integrally. The frame portion 320 is connected to the rear surface of the lens panel 200, and the connection-providing end 310 is configured to switch the propagation path of the laser. Here, the connection-providing end 310 is divided into an overlapping section A that overlaps with the grid panel 100 and a non-overlapping section B that does not overlap with the grid panel 100. That is, in the connection-providing end 310, the non-overlapping section B is the space where laser light emitted from the front side is incident to the rear side, and the overlapping section A is the space where laser light that is not incident from the outside and has a switched propagation path propagates to the rear surface of the grid panel 100.

[0054] Therefore, the connection end 310 can be applied in various examples, such as those below.

[0055] like Figure 3 As shown, according to the first example, the connection provides an end 310 that extends obliquely from the frame portion 320 to the rear side to form an oblique surface, such that laser light incident from the front side can be reflected from the oblique surface to propagate to the rear surface of the grille panel 100.

[0056] As described above, the connection-providing end 310 of the housing 300 extends obliquely from the frame portion 320 toward the rear side in a straight line, such that when a laser emitted from the front side to the rear side is incident on the oblique surface, the propagation path of the laser is switched. Here, the oblique angle of the connection-providing end 310 is set to allow the incident laser to be incident on the rear surface of the grille panel 100.

[0057] Here, in the connection providing end 310, the non-overlapping section B of the inclined surface on which the laser is incident undergoes a surface treatment to increase the reflectivity of the corresponding section. That is, the non-overlapping section B of the connection providing end 310 is formed to increase the reflectivity of the corresponding section through aluminum deposition or electroplating.

[0058] Therefore, when the laser emission position is fixed so that the laser is emitted from the front side to the rear side and moves toward the lateral side, the laser's movement position can be adjusted on the rear surface of the grille panel 100 because the movement position of the laser reflected by the inclined surface of the end 310 is changed.

[0059] At the same time, such as Figure 4As shown, according to the second example, the portion of the grid panel 100 is bent rearward, such that a bent portion 210 can be formed in the lens panel 200, and a fusion portion 110 can be formed in the grid panel 100 to match and be disposed on the bent portion 210 of the lens panel 200, and the connection end 310 of the housing 300 can be formed to extend obliquely from the frame portion 320 toward the rearward to allow laser light incident from the front to propagate to the fusion portion 110 of the grid panel 100.

[0060] Therefore, in the grid panel 100, the fusion portion 110 is disposed on the curved portion 210 of the lens panel 200, such that the fusion position of the grid panel 100 can be set closer to the connection providing end 310. Here, the connection providing end 310 of the housing 300 extends obliquely from the frame portion 320 to the rear side, such that the propagation path of the laser emitted from the front side to the rear side is switched due to the connection providing end 310. The tilt angle of the connection providing end 310 can be set to allow the incident laser to be incident on the fusion portion 110 of the grid panel 100.

[0061] Furthermore, the curved portion 210 and the fused portion 110 are formed to extend in a direction perpendicular to the propagation direction of the laser, thereby improving the incident efficiency of the laser, which is reflected to propagate through the connecting end 310. Additionally, in the connecting end 310, the non-overlapping segment B on which the laser is incident undergoes a surface treatment to increase the reflectivity of the corresponding segment.

[0062] Therefore, the laser emitted from the front to the rear can be reflected from the inclined surface of the coupling end 310, pass through the curved portion 210 of the lens panel 200, and then be incident on the fusion portion 110 of the grid panel 100. In particular, the fusion portion 110 of the grid panel 100 protrudes toward the coupling end 310 and extends in a direction perpendicular to the incident direction of the laser, thereby improving the incident efficiency of the laser and thus improving the connection performance between the grid panel 100 and the lens panel 200.

[0063] At the same time, such as Figure 5 As shown, according to the third example, the connection provides an end 310 that extends in the frame portion 320 to have a parabola, thereby forming a curved surface such that laser light incident from the front side can propagate to the rear surface of the grille panel 100.

[0064] As described above, the connection-providing end 310 of the housing 300 extends rearward from the frame portion 320 and bends so that when a laser emitted from the front to the rear is incident on an inclined surface forming a parabola, the propagation path of the laser is switched. Here, the curvature of the connection-providing end 310 is set to allow the incident laser to be incident on the rear surface of the grille panel 100 with a focal point.

[0065] Furthermore, in the connection providing end 310, the non-overlapping section B of the curved surface on which the laser is incident undergoes a surface treatment to increase the reflectivity of the corresponding section. That is, the non-overlapping section B of the connection providing end 310 is formed to increase the reflectivity of the corresponding section through aluminum deposition or electroplating.

[0066] Therefore, when the laser is emitted from the front to the rear and incident on the connection providing end 310, the propagation path of the laser moves to the rear surface of the grid panel 100 due to the parabolic shape of the connection providing end 310. In particular, in the connection providing end 310, due to the parabolic shape, the focal point is set on the rear surface of the grid panel 100 that contacts the front surface of the lens panel 200, so that even when the laser emission position moves in the lateral direction, the laser is precisely incident on the rear side of the grid panel 100.

[0067] At the same time, such as Figure 6 As shown, according to the fourth example, the portion of the grid panel 100 is bent rearward, such that a bent portion 210 can be formed in the lens panel 200, and a fusion portion 110 can be formed in the grid panel 100 to match and be disposed on the bent portion 210 of the lens panel 200, and the connection end 310 of the housing 300 can extend rearward from the frame portion 320 to have a parabola, and can be formed to be bent to allow laser light incident from the front to propagate to the fusion portion 110 of the grid panel 100.

[0068] Therefore, in the grille panel 100, the fusion portion 110 is disposed on the curved portion 210 of the lens panel 200, such that the fusion position of the grille panel 100 can be set closer to the connection providing end 310. Here, the connection providing end 310 of the housing 300 extends and bends rearward from the frame portion 320, such that the propagation path of the laser emitted from the front to the rear can be switched due to the connection providing end 310, so that the laser can be incident on the rear surface of the grille panel 100. The curvature of the connection providing end 310 can be set to allow the incident laser to be incident on the fusion portion 110 of the grille panel 100.

[0069] Furthermore, the curved portion 210 and the fused portion 110 are formed to extend in a direction perpendicular to the propagation direction of the laser, thereby improving the incident efficiency of the laser, which is reflected to propagate through the connecting end 310. Additionally, in the connecting end 310, the non-overlapping segment B to which the laser is incident can be formed to undergo a surface treatment to increase the reflectivity of the corresponding segment.

[0070] Therefore, the laser emitted from the front to the rear is reflected from the curved surface of the connection providing end 310, passes through the curved portion 210 of the lens panel 200, and then incident on the fusion portion 110 of the grid panel 100. In particular, the fusion portion 110 of the grid panel 100 protrudes toward the connection providing end 310 and extends in a direction perpendicular to the incident direction of the laser, thereby improving the incident efficiency of the laser and thus improving the connection performance between the grid panel 100 and the lens panel 200.

[0071] At the same time, such as Figure 7 As shown, according to the fifth example, the connection providing end 310 includes a first reflective end 330 located in the non-overlapping section B and extending obliquely in a straight line from the frame portion 320 to the rear side, and includes a second reflective end 340 located in the overlapping section A and extending obliquely in a straight line from the first reflective end 330 to the front side. Therefore, laser light incident from the front side can be reflected by the first reflective end 330 to propagate to the second reflective end 340, and then reflected by the second reflective end 340 to propagate to the rear surface of the grille panel 100.

[0072] As described above, the connection end 310 of the housing 300 is formed by a first reflective end 330 extending obliquely toward the rear and a second reflective end 340 extending obliquely from the first reflective end 330 toward the front, such that a laser emitted from the front to the rear can be reflected from the first reflective end 330 to propagate to the second reflective end 340, and then reflected again from the second reflective end 340 to be incident on the rear surface of the grille panel 100. Here, the tilt angle of the first reflective end 330 can be set to allow the incident laser to propagate toward the second reflective end 340, and the tilt angle of the second reflective end 340 can be set to allow its propagation path to move through the first reflective end 330 and onto the rear side of the grille panel 100.

[0073] The first reflective end 330 and the second reflective end 340 undergo surface treatment to increase the reflectivity of the corresponding sections. In other words, the first reflective end 330 and the second reflective end 340 can be formed to have high reflectivity through aluminum deposition or electroplating.

[0074] Therefore, when the laser emission position is moved laterally in a fixed state to emit laser from the front to the rear, the propagation position of the laser reflected by the first reflective end 330 and the second reflective end 340 of the connecting end 310 is adjusted so that the incident position of the laser can be precisely matched to the rear side of the grid panel 100.

[0075] At the same time, such as Figure 8As shown, according to the sixth example, the connection end 310 includes a first curved end 350 and a second curved end 360. The first curved end 350 is located in the non-overlapping section B and extends rearward from the frame portion 320 in a parabolic shape. The second curved end 360 is located in the overlapping section A and extends forward from the first curved end 350 in a parabolic shape. Therefore, laser light incident from the front can be reflected by the first curved end 350 to propagate to the second curved end 360, and then reflected by the second curved end 360 to propagate toward the rear surface of the grille panel 100.

[0076] As described above, the connection end 310 of the housing 300 is formed by a first curved end 350 extending toward the rear and a second curved end 360 extending from the first curved end 350 toward the front, such that a laser emitted from the front to the rear can be reflected from the first curved end 350 to propagate to the second curved end 360, and then reflected again from the second curved end 360 to incident on the rear surface of the grille panel 100. Here, the curvature of the first curved end 350 can be configured to allow the incident laser to propagate toward the second curved end 360, and the curvature of the second curved end 360 can be configured to allow its propagation path to move through the first curved end 350 and onto the rear side of the grille panel 100.

[0077] The first curved end 350 and the second curved end 360 undergo surface treatment to increase the reflectivity of the corresponding sections. In other words, the first curved end 350 and the second curved end 360 can be formed to have high reflectivity through aluminum deposition or electroplating.

[0078] Therefore, when a laser is emitted from the front to the rear and incident on the first curved end 350 forming the connection-providing end 310, the laser propagates to the second curved end 360 due to the parabolic shape of the first curved end 350. Furthermore, due to the parabolic shape of the second curved end 360, the laser incident on the second curved end 360 propagates to the rear surface of the grille panel 100. Specifically, the focal point of the first curved end 350, according to its parabolic shape, is located in the second curved end 360, and the focal point of the second curved end 360, according to its parabolic shape, is located on the rear surface of the grille panel 100, such that even when the laser emission position moves in the lateral direction, the laser is precisely incident on the rear surface of the grille panel 100.

[0079] At the same time, such as Figure 9As shown, one of the frame portions 320 of the housing 300 is formed to have a longer length facing forward, and when the lens panel 200 and the housing 300 are connected, the longer frame portion 320 can be connected to the lens panel 200, and then the other frame portion 320 can be connected to the lens panel 200.

[0080] In other words, a pair of frame portions 320 of the housing 300 are joined to the lens panel 200 by laser fusion. However, due to the characteristics of laser melting, the frame portion 320 to which the laser is incident is melted, thus reducing the length of the frame portion 320. Therefore, when the frame portions 320 have the same length and one of the frame portions 320 is fused, fusing the other frame portion 320 is difficult.

[0081] Therefore, any one of the frame portions 320 should be formed to have a longer length facing forward. Thus, when the lens panel 200 and the housing 300 are joined, the longer frame portion 320 is fused to the lens panel 200 first, and then the other frame portion 320 is fused to the lens panel 200, thereby suppressing unstable fusion due to length deviation.

[0082] At the same time, such as Figure 1 and 10 As shown, the vehicle grille according to this disclosure includes: a grille panel 100, which constitutes a grille design; a lens panel 200 disposed in the rear surface of the grille panel 100, formed with the same shape as a portion or the entire area of ​​the grille panel 100, and configured to allow light to propagate inside the lens panel 200 when light is incident, and to emit a portion of the light to the outside; and a housing 300 disposed in the rear surface of the lens panel 200, formed with the same shape as the lens panel 200, and having a connection providing hole 370 that allows the grille panel 100 to be connected to the front surface of the lens panel 200 when the lens panel 200 is connected to the front surface of the housing 300.

[0083] As described above, according to this disclosure, to improve the ease of connection between the grille panel 100, the lens panel 200, and the housing 300, a connection providing hole 370 is formed in the housing 300. The connection providing hole 370 allows the rear surface of the grille panel 100 to be connected to the front surface of the lens panel 200, the lens panel 200 being connected to the front surface of the housing 300 from its rear side, and the rear surface of the grille panel 100 being connected to the front surface of the lens panel 200 from its rear side via the connection providing hole 370 in the housing 300. Therefore, the grille panel 100 can be connected to the front surface of the lens panel 200, and the housing 300 can be connected to the rear surface of the lens panel 200.

[0084] Specifically, the grille panel 100, lens panel 200, and housing 300 can be fused and joined due to laser emission. Since the lens panel 200 is configured to allow light to pass through, a laser emitted from the front to the rear passes through the lens panel 200 and enters the front surface of the housing 300. Therefore, the rear surface of the lens panel 200 and the front surface of the housing 300 can be fused together due to the laser.

[0085] Simultaneously, when the grille panel 100 and the lens panel 200 are joined, the laser should be incident on the rear surface of the grille panel 100. For this purpose, a connection hole 370 is formed in the housing 300, thereby allowing the laser emitted from the rear to the front to be incident on the rear surface of the grille panel 100, so that the rear surface of the grille panel 100 and the front surface of the lens panel 200 can be fused together by laser.

[0086] At the same time, such as Figure 10 As shown, the housing 300 is connected to the rear surface of the lens panel 200 via the peripheral portion 380 of the connection providing hole 370, and the grid panel 100 is configured to face the connection providing hole 370 of the housing 300 to be connected to the front surface of the lens panel 200, such that the housing 300 and the grid panel 100 do not overlap each other in the front-rear direction.

[0087] As described above, since the grille panel 100 and the housing 300 do not overlap in the front-rear direction within the lens panel 200, the grille panel 100 and the housing 300 can be easily fused to the lens panel 200 by laser fusion. That is, from Figure 10 As can be seen, when the grid panel 100 is fused to the lens panel 200, the laser emitted from the rear side of the lens panel 200 bypasses the housing 300 and is incident on the grid panel 100, so that the grid panel 100 can be fused to the lens panel 200. And when the housing 300 is fused to the lens panel 200, the laser emitted from the front side of the lens panel 200 bypasses the grid panel 100 and is incident on the housing 300, so that the housing 300 can be fused to the lens panel 200.

[0088] Meanwhile, as another example, in the housing 300, the peripheral portion 380 of the connection providing hole 370 can be connected to the rear surface of the lens panel 200, and the housing 300 and the lens panel 200 can be connected by an extension end 390, which extends from the rear surface of the lens panel 200 toward the peripheral portion 380 of the housing 300 or from the peripheral portion 380 of the housing 300 toward the rear surface of the lens panel 200. Here, the extension end 390 can extend from the peripheral portion 380 of the housing 300 to be integrally formed with the housing 300, or it can extend from the lens panel 200 to be integrally formed with it. However, for the sake of understanding this disclosure in the following description, it is assumed that the extension end 390 is formed in the housing 300.

[0089] In other words, the extended ends 390 of the housing 300, which are connected to the rear surface of the lens panel 200, are spaced apart in the width direction of the lens panel 200, and the grille panel 100 is disposed on the front surface of the lens panel 200 between the extended ends 390 of the housing 300 to connect to the lens panel 200, such that the grille panel 100 and the housing 300 do not overlap in the front-rear direction based on the lens panel 200. Here, in the housing 300, the extended ends 390 are formed to be recessed on the side opposite to the lens panel 200, so when light propagating in the lens panel 200 propagates to the recessed portion formed by the extended ends 390, the light is reflected to propagate to the front side, thereby providing emission efficiency of light emitted through the lens panel 200. Furthermore, in the lens panel 200, optical portions 220 formed by a plurality of protrusions or grooves are formed in portions that match the recessed portions formed by the extended ends 390, so light is scattered by the optical portions 220, thereby further providing the amount of light emitted to the front side of the lens panel 200. When the optical portion 220 is formed at the location where the lens panel 200 and the grid panel 100 are in contact with each other or at the location where the lens panel 200 and the housing 300 are in contact with each other, the optical portion 220 will act as a fusion suppression factor, such that preferably the optical portion 220 is formed only in the recessed portion between the extended ends 390.

[0090] The vehicle grille formed by the above structure allows the lights to be turned on within the grille and diffused gently from the rear side of the grille, thus enhancing the grille's appearance. Furthermore, it facilitates the connection of the grille panel 100, lens panel 200, and housing 300 that form the grille, thereby improving ease of operation and productivity.

[0091] Although the specific form of this disclosure has been described and illustrated, those skilled in the art will understand that various substitutions and modifications can be made without departing from the technical spirit of this disclosure as provided in the appended claims.
