Description

[Technical Field]

[0001] The present invention relates to a peripheral structure for a vehicle headlight. [Background technology]

[0002] Conventionally, vehicle bumpers have been attached to the vehicle body using bolts and clips. Bumpers have a certain degree of flexibility to absorb impacts, and applying excessive torque when tightening the bolts can cause deformation. Therefore, the bumper installation work required adjustments to avoid affecting the positional relationship with the headlights.

[0003] For example, Patent Document 1 is a technology related to a vehicle lighting fixture, and discloses a headlamp 1 surrounded by a bumper 2. In Patent Document 1, as shown in Fig. 2, a bumper holding portion 62 for holding the bumper 2 is provided near the lower edge of the outer lens 6 of the headlamp 1.

DETAILED DESCRIPTION OF THE INVENTION

[0010] A vehicle headlight peripheral structure according to one embodiment of the present invention comprises a headlight unit attached to the front of a vehicle body and a bumper attached to the vehicle body so as to cover the headlight unit, wherein the bumper has a bumper body exposed to the outside of the vehicle, an opening opened in a predetermined position of the bumper body to expose the headlight unit, and a rib provided along the edge of the opening and extending in a curved manner from the bumper body towards the vehicle body, the headlight unit has a base connected to the vehicle body, a lens portion protruding from the base towards the opening and exposed from the opening, an outer light convex portion of the base protruding forward of the vehicle from the outer side of the lens portion in the vehicle width direction and contacting the rib from the outside in the vehicle width direction, and a lower light convex portion of the base protruding forward of the vehicle from below the lens portion, and the bumper further has a lower bumper convex portion provided below the opening and protruding downward from the rib and contacting the lower light convex portion.

[0011] According to the above configuration, the bumper rib and the lower bumper convex portion contact each light convex portion of the headlight unit, thereby regulating the position of the bumper and enabling the parting line with the bumper around the lens portion to be formed with high precision. In particular, with the above configuration, the light convex portions are provided on the outer side and below the lens portion in the vehicle width direction. In other words, with the above configuration, the bumper can be brought into contact with each of the left and right headlight units from the outer side and below in the vehicle width direction to align them, efficiently improving the precision of the parting line of the headlight units on the front of the vehicle.

[0012] Furthermore, with the above-described configuration, the headlight unit and the bumper are not directly fastened to each other, which reduces distortion of the bumper caused by external forces during fastening. This configuration also makes it possible to form the parting line around the lens with high precision and to make it easy to correct the parting line.

[0013] The bumper body includes a front wall extending in the vehicle width direction along the front part of the vehicle body, and a side wall extending from the vehicle width end of the front wall along the side part of the vehicle body toward the rear of the vehicle, and a gap is formed in the vehicle fore-and-aft direction between the outer light convexity and the front wall, and a gap is formed in the vehicle width direction between the outer light convexity and the side wall.

[0014] The outer light protrusions only contact the ribs of the bumper, not the bumper body itself. This configuration reduces the chance of the bumper body interfering with the headlight unit when an impact is applied to the bumper body in a minor collision, thereby minimizing damage to the headlight unit.

[0015] The headlight unit further includes a predetermined holder member attached to the periphery of the lens portion of the base, and the outer light convex portion and the lower light convex portion are provided on the holder member.

[0016] According to the above configuration, by providing each light protrusion on the holder member that is a separate part from the base of the headlight unit, it becomes easy to adjust the contact condition between each light protrusion and the bumper, and it becomes possible to standardize the base of the headlight unit among different vehicle models, thereby increasing its versatility. Furthermore, by providing each light protrusion on the holder member, even if the bumper interferes with each light protrusion due to a minor collision or the like, the holder member can absorb the impact, thereby reducing damage to the base of the headlight unit.

[0017] A predetermined gap is formed between the lower light convex portion and the base portion of the holder member.

[0018] With the above configuration, when the bumper interferes with the holder member due to a minor collision or the like, the chances of the holder member interfering with the base of the headlight unit are reduced, and damage to the base of the headlight unit can be suppressed.

[0019] The headlight unit further includes an upper light convex portion that protrudes from above the lens portion of the base toward the front of the vehicle, and the bumper further has an upper bumper convex portion that is provided above the opening and protrudes upward from the rib and contacts the side of the upper light convex portion.

[0020] According to the above configuration, by providing an upper light convex portion also on the upper side of the lens portion and positioning it with the bumper, it is possible to further improve the accuracy of the parting line around the lens portion. [Example]

[0030] An upper bumper protrusion 128 and a lower bumper protrusion 130 are provided around the rib 126 as portions for positioning the headlight unit 104. The upper bumper protrusion 128 is provided above the opening 108, and protrudes upward and toward the rear of the vehicle from the upper side of the rib 126. The lower bumper protrusion 130 is provided below the opening 108, and protrudes downward from the lower side of the rib 126.

[0031] Fig. 3 is a view of the headlight structure 100 of Fig. 1 as viewed from the front of the vehicle. Fig. 3(a) is a view of the headlight structure 100 of Fig. 1(a) as viewed from the front of the vehicle. When the headlight structure 100 is viewed from the front of the vehicle, the lens portion 110 of the headlight unit 104 is surrounded by the bumper main body 106, and the flange portion 120 (see Fig. 1(b)) and the holder member 114 are covered and hidden by the bumper main body 106.

[0032] Fig. 3(b) is a view of the headlight unit 104 of Fig. 1(b) viewed from the front of the vehicle. When viewed from the front of the vehicle, the holder member 114 is shaped to surround the flange portion 120 around the lens portion 110 in a range extending from the outer side to the lower side in the vehicle width direction.

[0033] The outer light protrusion 122 and the lower light protrusion 124 are portions of the holder member 114 that protrude toward the front of the vehicle. The outer light protrusion 122 is formed on the outer side of the lens portion 110 in the vehicle width direction. The lower light protrusion 124 is formed below the lens portion 110.

[0034] In addition to the above-mentioned light protrusions, the headlight body 112 is also provided with an upper light protrusion 132. The upper light protrusion 132 is also a part that protrudes forward of the vehicle, and is provided at a location on the flange portion 120 above the lens portion 110.

[0035] Figure 4 is a cross-sectional view of the headlight structure 100 of Figure 3(a). Figure 4(a) is a cross-sectional view of the headlight structure 100 of Figure 3(a) taken along line AA.

[0036] In the bumper 102, a bumper recess 134 is formed on the rear side around the opening 108 by the bumper body 106 and the rib 126. Each of the light protrusions described above is fitted into this bumper recess 134 to position the bumper 102.

[0037] The outer light protrusion 122 is fitted into a location on the outer side in the vehicle width direction of the bumper recess 134 of the bumper 102. The outer light protrusion 122 contacts the rib 126 from the outer side in the vehicle width direction and grips the rib 126 at a portion on the inner side in the vehicle width direction.

[0038] Figure 4(b) shows the same a) is a BB cross-sectional view of the headlight structure 100. The lower light convex portion 124 contacts a lower bumper convex portion 130 of the bumper 102. More specifically, below the lens portion 110, the lower bumper convex portion 130 protrudes downward from the lower surface of the rib 126, and the lower end of the lower bumper convex portion 130 contacts an upper surface 136 of the lower light convex portion 124 of the holder member 114.

[0039] 3(b), the lower light protrusion 124 has a lower portion 124a and an inner portion 124b provided on the inner side of the lower portion 124a in the vehicle width direction when viewed from the front of the vehicle. The inner portion 124b is formed higher than the lower portion 124a, and an interior angle 138 is formed between the inner portion 124b and the lower portion 124a. The lower bumper protrusion 130 described above fits into this interior angle 138, and its lower end contacts an upper surface 136 of the lower portion 124a.

[0040] Fig. 5 is a cross-sectional view of the headlight structure 100 of Fig. 3(a). Fig. 5(a) is a CC cross-sectional view of the headlight structure 100 of Fig. 3(a). As shown in Fig. 5(a), the inner portion of the lower bumper protrusion 130 in the vehicle width direction contacts the outer side surface 140 in the vehicle width direction of the inner portion 124b of the lower light protrusion 124.

[0041] Fig. 5(b) is a DD cross-sectional view of the headlight structure 100 of Fig. 3(b). The upper bumper protrusion 128 comes into contact with the upper light protrusion 132 of the flange portion 120. More specifically, the upper bumper protrusion 128 protrudes upward and rearward from the rib 126 above the opening 108 (see Fig. 2), and comes into contact with the outer side of the upper light protrusion 132 in the vehicle width direction.

[0042] As described above, in this embodiment, the outer light convex portion 122, the lower light convex portion 124, and the upper light convex portion 132 are provided around the lens portion 110 of the headlight unit 104, and each light convex portion comes into contact with the rib 126 of the bumper 102, the lower bumper convex portion 130, and the upper bumper convex portion 128. This allows the headlight unit 104 to regulate the position of the bumper 102. With this configuration, it is possible to accurately form the parting line between the lens portion 110 and the opening 108 to a set width, etc.

[0043] In this embodiment, outer light convex portions 122 and lower light convex portions 124 can be provided on the outer side and lower side in the vehicle width direction of each lens portion 110. With this configuration, the bumper 102 can be brought into contact with each of the left and right headlight units 104 from the outer side and lower side in the vehicle width direction to align them, making it possible to efficiently improve the accuracy of the parting lines of the headlight units 104 on the front of the vehicle. In particular, with this configuration, the lower side of the lens portion 110 can be supported by the bumper 102, making it possible to correct misalignment of the parting lines due to the weight of the headlight units 104 with a simple configuration.

[0044] In this embodiment, by providing an upper light convex portion 132 also on the upper side of the lens portion 110 to position the bumper 102, it is possible to further improve the accuracy of the parting line around the lens portion 110.

[0045] In this embodiment, the headlight unit 104 and the bumper 102 are not directly fastened to each other, which makes it possible to prevent distortion of the bumper 102 due to external forces that may occur during fastening. This configuration also makes it possible to form the parting line around the lens portion 110 with high precision and to make it easy to correct the parting line.

[0046] In this embodiment, by providing the outer light convex portion 122 and the lower light convex portion 124 on the holder member 114, which is a separate part from the headlight body 112, it is possible to easily adjust the degree of contact between the outer light convex portion 122 and the lower light convex portion 124 and the bumper 102. In addition, by making the holder member 114 an independent member, it is possible to standardize the headlight body 112 between different vehicle models, thereby increasing its versatility.

[0047] Furthermore, by providing the holder member 114 with the outer light protrusion 122, etc., even if the bumper 102 interferes with the outer light protrusion 122, etc. due to a minor collision or the like, the holder member 114 receives the impact, making it possible to prevent damage to the headlight body 112.

[0048] 4(a) again, a gap S1 is formed in the vehicle longitudinal direction between the tip of the outer light protrusion 122 and the front wall 106a of the bumper main body 106. Furthermore, a gap S2 is formed in the vehicle width direction between the outer light protrusion 122 and the side wall 106b.

[0049] The outer light protrusion 122 contacts only the rib 126 of the bumper 102, and does not contact the bumper body 106. With this configuration, when an impact is applied to the bumper body 106 due to a minor collision or the like, the chances of the bumper body 106 interfering with the headlight unit 104 are reduced, and damage to the headlight unit 104 can be suppressed.

[0050] 4(b), a gap S3 is formed in the vehicle longitudinal direction between the lower light protrusion 124 of the holder member 114 and the lower bumper protrusion 130 of the bumper 102. A gap S4 is formed in the vehicle longitudinal direction between the lower light protrusion 124 of the holder member 114 and the flange portion 120 of the headlight body 112.

[0051] The formation of gaps S3 and S4 also reduces the chance of the holder member 114 interfering with the headlight body 112 when the bumper 102 interferes with the holder member 114 due to a minor collision or the like, thereby preventing damage to the headlight body 112.

[0052] Figure 6 is a diagram showing a modified example (headlight unit 200) of the headlight unit of Figure 3(b). In Figure 6, the same components as those already explained in the above embodiment are given the same reference numerals, and explanations of these components will be omitted. Furthermore, in the following explanation, components with the same names as those already explained will have the same functions unless otherwise specified, even if they are given different reference numerals.

[0053] Book Transform The example headlight unit 200 differs in configuration from the headlight unit 104 in Figure 3(b) in that the holder member 114 (see Figure 3(b)) is omitted and the outer light protrusion 202 and the lower light protrusion 204 are provided directly on the flange portion 120.

[0054] 4, the outer light protrusion 202 contacts the rib 126 from the outer side in the vehicle width direction and grips the rib 126 with its inner side in the vehicle width direction. The outer light protrusion 202 can also form a gap S1 with the front wall 106a and a gap S2 with the side wall 106b.

[0055] 4(b), the lower end of the lower bumper protrusion 130 contacts the upper surface of the lower light protrusion 204. The lower light protrusion 204 can also form a gap S3 between itself and the lower bumper protrusion 130 of the bumper 102.

[0056] The headlight unit 200 also uses the outer light convex portion 202 and the lower light convex portion 204 to regulate the position of the bumper 102 and accurately form a parting line between the lens portion 110 and the opening 108. Furthermore, the headlight unit 200 forms gaps S1, S2, S3 (see FIG. 4 ) between the outer light convex portion 202 and the lower light convex portion 204 and the bumper 102, thereby reducing the chance of interference with the bumper main body 106 during a minor collision or the like and making it possible to avoid damage.

[0057] As a further modification, a light convex portion having a configuration symmetrical to the outer light convex portion 122 (see FIG. 3(b)) described above in the vehicle width direction can be provided at a location on the inner side of the lens portion 110 in the vehicle width direction. In this case, the holder member 114 may be configured to surround the lens portion 110 up to the inner side in the vehicle width direction, or the light convex portion may be provided directly on the flange portion 120 on the inner side of the lens portion 110 in the vehicle width direction. With this configuration, the bumper 102 can be positioned in the range from the outer side of the lens portion 110 to the lower side and inner side in the vehicle width direction, and the parting line around the lens portion 110 can be formed more accurately.

[0058] While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to these examples. It is clear that those skilled in the art can conceive of various modifications and alterations within the scope of the claims, and it is understood that these modifications and alterations also fall within the technical scope of the present invention.
