Description

Technical Field

[0001] The present invention relates to a peripheral structure of a vehicle headlight.

Background Art

[0002] Conventionally, when attaching a bumper of a vehicle, bolts, clips, etc. are used. The bumper has a certain degree of softness so that it can absorb impacts, and there is a risk of deformation if excessive torque is applied when tightening the bolts. Therefore, the bumper installation work needs to be carried out while adjusting so as not to affect the positional relationship with the headlight.

[0003] For example, Patent Document 1 is a technology related to a vehicle lamp, 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. In Patent Document 1, the bumper 2 is attached by supporting the bumper holding portion 62 with a support rod 60 protruding from the lamp housing 5.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the technology of Patent Document 1, since the bumper 2 is supported only on the lower side of the headlamp 1, it is conceivable that the alignment between the bumper 2 and the headlamp 1 becomes insufficient. In addition, when a minor collision or the like occurs, the bumper 2 and the headlamp 1 may interfere with each other, so in such a case, consideration of means for avoiding damage to the headlamp 1 is also required.

[0006] In view of these problems, the present invention aims to provide a vehicle headlight surrounding structure that can improve the accuracy of the dividing line between the bumper and the headlight and prevent damage to the headlight in the event of an impact. [Means for solving the problem]

[0007] To solve the above problems, a typical configuration of the vehicle headlight peripheral structure according to the present invention is a vehicle headlight peripheral structure comprising a headlight unit attached to the front of the 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 made at a predetermined location in the bumper body to expose the headlight unit, and ribs provided along the edge of the opening and extending from the bumper body toward the vehicle body in a curved manner, the headlight unit has a base connected to the vehicle body, a lens portion protruding from the base toward the opening and exposed from the opening, an outer light protrusion protruding from the side of the base on the outside in the vehicle width direction of the lens portion and contacting the rib from the outside in the vehicle width direction, and a lower light protrusion protruding from the base on the bottom of the lens portion and extending toward the vehicle forward, and the bumper further has a lower bumper protrusion provided below the opening and protruding downward from the rib and contacting the lower light protrusion. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a vehicle headlight surrounding structure that can improve the accuracy of the dividing line between the bumper and the headlight and prevent damage to the headlight in the event of an impact. [Brief explanation of the drawing]

[0009] [Figure 1] This figure shows an overview of a vehicle headlight peripheral structure according to an embodiment of the present invention. [Figure 2] Figure 1(a) is a perspective view of the bumper from the rear of the vehicle. [Figure 3] Figure 1 shows the headlight structure as viewed from directly in front of the vehicle. [Figure 4]Figure 3(a) shows cross-sectional views of the headlight structure. [Figure 5] Figure 3(a) shows cross-sectional views of the headlight structure. [Figure 6] Figure 3(b) shows a modified version of the headlight unit. [Modes for carrying out the invention]

[0010] A headlight peripheral structure for a vehicle according to one embodiment of the present invention comprises a headlight unit attached to the front of the vehicle body and a bumper attached to the vehicle body so as to cover the headlight unit. The bumper comprises a bumper body exposed to the outside of the vehicle, an opening made at a predetermined location in the bumper body to expose the headlight unit, and ribs provided along the edge of the opening and extending from the bumper body toward the vehicle body in a curved manner. The headlight unit comprises a base connected to the vehicle body, a lens portion protruding from the base toward the opening and exposed from the opening, an outer light projection protruding from the side of the base on the outside in the vehicle width direction of the lens portion and contacting the ribs from the outside in the vehicle width direction, and a lower light projection protruding from the base on the bottom of the lens portion and extending toward the vehicle forward. The bumper further comprises a lower bumper projection provided below the opening and protruding downward from the ribs and contacting the lower light projection.

[0011] With the above configuration, the bumper ribs and the lower bumper protrusions come into contact with each light protrusion of the headlight unit, thereby regulating the position of the bumper and allowing for the precise formation of a dividing line between the bumper and the lens around the lens. In particular, the above configuration provides light protrusions on both the outer and lower sides in the vehicle width direction relative to the lens. That is, with the above configuration, the bumper can be brought into contact with each of the left and right headlight units from the outer and lower sides in the vehicle width direction to align them, efficiently improving the accuracy of the dividing line of the headlight unit on the front of the vehicle.

[0012] Furthermore, in the above configuration, the headlight unit and the bumper are not directly fastened together, thus suppressing bumper distortion caused by external forces during fastening. This configuration also allows for the precise formation of the trim line around the lens and makes it easier to correct the trim line.

[0013] The bumper body described above includes a front wall extending in the vehicle width direction along the front of the vehicle body, and a side wall extending from the vehicle width direction end of the front wall along the side of the vehicle body towards the rear of the vehicle, with a gap formed in the vehicle longitudinal direction between the outer light protrusion and the front wall, and a gap formed in the vehicle width direction between the outer light protrusion and the side wall.

[0014] The outer light protrusions mentioned above contact only the ribs of the bumper and not the bumper body itself. This configuration reduces the chances of the bumper body interfering with the headlight unit in the event of an impact to the bumper body, such as during a minor collision, thereby minimizing damage to the headlight unit.

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

[0016] According to the above configuration, by providing each light protrusion on a holder member, which is a separate part from the base of the headlight unit, it becomes easier to adjust the contact between each light protrusion and the bumper. Furthermore, it becomes possible to standardize the base of the headlight unit across different vehicle models, thereby increasing its versatility. In addition, by providing each light protrusion on the holder member, even if the bumper interferes with each light protrusion in a minor collision, the holder member will absorb the impact, thus preventing damage to the base of the headlight unit.

[0017] A predetermined gap is formed between the lower light protrusion and the base of the holder member described above.

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

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

[0020] According to the above configuration, by providing the upper light convex portion also above the lens portion and positioning it with the bumper, it becomes possible to further improve the accuracy of the cut-off line around the lens portion.

In the present specification and drawings, elements having substantially the same functions and configurations are denoted by the same reference numerals to omit redundant explanations, and elements not directly related to the present invention are not shown.

[0022] FIG. 1 is a diagram showing an overview of a vehicle headlight peripheral structure (hereinafter, headlight structure 100) according to an embodiment of the present invention. FIG. 1(a) is a perspective view showing the headlight structure 100 on the left side of the vehicle. Hereinafter, in FIG. 1 and all other drawings of the present application, the vehicle front-rear direction is exemplified by arrows F (Forward), B (Backward), the left and right in the vehicle width direction are exemplified by arrows L (Leftward), R (Rightward), and the vehicle up-down direction is exemplified by arrows U (upward), D (downward).

[0023] The headlight structure 100 comprises a bumper 102 and a headlight unit 104. In this embodiment, the bumper 102 is implemented as a front bumper and is mounted on the front structure of the vehicle body so as to cover the headlight unit 104. The bumper 102 is not directly fixed to the headlight unit 104.

[0024] The bumper body 106 is the portion of the bumper 102 that is exposed to the outside of the vehicle. The bumper body 106 includes a front wall 106a and a side wall 106b. The front wall 106a is the portion that extends in the vehicle width direction along the front of the vehicle body. The side wall 106b extends from the vehicle width direction end of the front wall 106a along the side of the vehicle body, curving toward the rear of the vehicle.

[0025] The opening 108 is the part that exposes the lens portion 110 of the headlight unit 104, and is formed in such a state that it penetrates through the front-rear direction of the vehicle at the vicinity of both ends in the vehicle width direction of the front wall 106a.

[0026] Figure 1(b) shows the headlight unit 104 exposed by removing the bumper 102 from Figure 1(a). The headlight unit 104 has a headlight body 112 and a holder member 114, which will be described later, and is attached to the structure at the front of the vehicle body.

[0027] The headlight body 112 consists of a base 116 and a lens portion 110. The base 116 is the main part of the headlight body 112 and is attached to the vehicle body by a plurality of fixing parts such as fixing parts 118a to 118c. The lens portion 110 is a transparent structure that covers the front of the light source, protruding from the base 116 toward the opening 108 and being exposed from the opening 108.

[0028] The holder member 114 is a resin component attached around the lens portion 110. The holder member 114 is attached to the flange portion 120 surrounding the lens portion 110 of the base portion 116 using bolts or the like. The holder member 114 has multiple light protrusions, such as the outer light protrusion 122 and the lower light protrusion 124, and the bumper 102 is positioned using each of these light protrusions.

[0029] Figure 2 is a perspective view of the bumper 102 shown in Figure 1(a) from the rear of the vehicle. The bumper 102 is provided with a rib 126 that borders the rear side of the opening 108. The rib 126 is formed to bend and extend from the bumper body 106 toward the rear of the vehicle body along the edge of the opening 108. The outer light protrusion 122 of the holder member 114 (see Figure 1(b)) mentioned above interferes with this rib 126 to position the bumper 102.

[0030] Around the rib 126, an upper bumper projection 128 and a lower bumper projection 130 are provided as positions for the headlight unit 104. The upper bumper projection 128 is located above the opening 108 and protrudes upward and rearward from the upper side of the rib 126. The lower bumper projection 130 is located below the opening 108 and protrudes downward from the lower side of the rib 126.

[0031] Figure 3 is a view of the headlight structure 100 of Figure 1, looking directly at it from the front of the vehicle. Figure 3(a) is a view of the headlight structure 100 of Figure 1(a), looking directly at it from the front of the vehicle. When the headlight structure 100 is viewed from the front of the vehicle, the area around the lens portion 110 of the headlight unit 104 is surrounded by the bumper body 106, and the flange portion 120 (see Figure 1(b)) and the holder member 114 are covered by the bumper body 106.

[0032] Figure 3(b) is a view of the headlight unit 104 of Figure 1(b) as seen from the front of the vehicle. When viewed from the front of the vehicle, the holder member 114 has a shape that encloses the area of ​​the flange portion 120 surrounding the lens portion 110, from the outer side in the vehicle width direction to the bottom.

[0033] The outer light projection 122 and the lower light projection 124 are parts of the holder member 114 that protrude forward of the vehicle. The outer light projection 122 is formed on the side of the lens portion 110, on the outer side in the vehicle width direction. The lower light projection 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 on the flange portion 120 above the lens portion 110.

[0035] Figure 4 shows various cross-sectional views of the headlight structure 100 in Figure 3(a). Figure 4(a) is a cross-sectional view AA of the headlight structure 100 in Figure 3(a).

[0036] The bumper 102 has a bumper recess 134 formed on the rear side around the opening 108 by the bumper body 106 and the rib 126. The aforementioned light protrusions are fitted into this bumper recess 134 to position the bumper 102.

[0037] The outer light protrusion 122 is fitted into 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 with the inner side in the vehicle width direction.

[0038] Figure 4(b) is a cross-sectional view of the BB of the headlight structure 100 shown in Figure 3(b). The lower light projection 124 contacts the lower bumper projection 130 of the bumper 102. More specifically, below the lens portion 110, the lower bumper projection 130 protrudes downward from the lower surface of the rib 126, and the lower end of this lower bumper projection 130 contacts the upper surface 136 of the lower light projection 124 of the holder member 114.

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

[0040] Figure 5 shows cross-sectional views of the headlight structure 100 in Figure 3(a). Figure 5(a) is a cross-sectional view of the headlight structure 100 in Figure 3(a). As shown in Figure 5(a), the portion of the lower bumper projection 130 that is on the inside 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 projection 124.

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

[0042] As described above, in this embodiment, the headlight unit 104 is provided with an outer light protrusion 122, a lower light protrusion 124, and an upper light protrusion 132 around the lens portion 110, and each light protrusion contacts the rib 126 of the bumper 102, the lower bumper protrusion 130, and the upper bumper protrusion 128. In this way, the headlight unit 104 can regulate the position of the bumper 102. With this configuration, it becomes possible to accurately form the dividing line between the lens portion 110 and the opening 108 to the set width, etc.

[0043] In this embodiment, outer light protrusions 122 and lower light protrusions 124 can be provided on the outer and lower sides of each lens portion 110 in the vehicle width direction. With this configuration, the bumper 102 can be brought into contact with each of the left and right headlight units 104 from the outer and lower sides in the vehicle width direction to align them, making it possible to efficiently improve the accuracy of the line of the headlight unit 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 the misalignment of the line of the headlight unit 104 due to its weight with a simple configuration.

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

[0045] In this embodiment, the headlight unit 104 and the bumper 102 are not directly fastened together, thus suppressing distortion of the bumper 102 due to external forces during fastening. This configuration also allows for the precise formation of the trim line around the lens portion 110 and makes it easier to correct the trim line.

[0046] In this embodiment, by providing the outer light protrusion 122 and the lower light protrusion 124 on a 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 protrusion 122 and the lower light protrusion 124 and the bumper 102. In addition, by making the holder member 114 an independent part, it is possible to standardize the headlight body 112 across different vehicle models, thereby increasing its versatility.

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

[0048] Refer again to Figure 4(a). A gap S1 is formed in the vehicle's longitudinal direction between the tip of the outer light projection 122 and the front wall 106a of the bumper body 106. In addition, a gap S2 is formed in the vehicle's width direction between the outer light projection 122 and the side wall 106b.

[0049] The outer light protrusion 122 described above contacts only the rib 126 of the bumper 102 and does not contact the bumper body 106. With this configuration, when the bumper body 106 is subjected to impact, such as in a minor collision, the opportunity for the bumper body 106 to interfere with the headlight unit 104 is reduced, thereby suppressing damage to the headlight unit 104.

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

[0051] The formation of gaps S3 and S4 reduces the chances of the holder member 114 interfering with the headlight body 112 when the bumper 102 interferes with the holder member 114 during a minor collision, thereby suppressing damage to the headlight body 112.

[0052] Figure 6 shows a modified example (headlight unit 200) of the headlight unit in Figure 3(b). In Figure 6, the same reference numerals are used for components that have already been described in the above embodiment, and thus the explanation of previously described components is omitted. In the following explanation, components with the same name as those already described will be considered to have the same function even if they are given different reference numerals, unless otherwise specified.

[0053] The headlight unit 200 in this embodiment differs in configuration from the headlight unit 104 in Figure 3(b) in that it omits the holder member 114 (see Figure 3(b)) and provides the outer light projection 202 and the lower light projection 204 directly on the flange portion 120.

[0054] The outer light projection 202, similar to the outer light projection 122 in Figure 4, contacts the rib 126 from the outside in the vehicle width direction and grips the rib 126 with the portion on the inside in the vehicle width direction. The outer light projection 202 can also form a gap S1 with the front wall 106a and a gap S2 with the side wall 106b.

[0055] Similar to the lower light projection 124 in Figure 4(b), the lower end of the lower bumper projection 130 contacts the upper surface of the lower light projection 204. The lower light projection 204 can also form a gap S3 between itself and the lower bumper projection 130 of the bumper 102.

[0056] The headlight unit 200 also utilizes the outer light protrusion 202 and the lower light protrusion 204 to regulate the position of the bumper 102, making it possible to accurately form the dividing line between the lens portion 110 and the opening 108. Furthermore, the headlight unit 200 reduces the chances of interference with the bumper body 106 during a minor collision, etc., by forming gaps S1, S2, S3 (see Figure 4) between the outer light protrusion 202 and the lower light protrusion 204 and the bumper 102, thereby avoiding damage.

[0057] As a further modification, a light protrusion symmetrical to the outer light protrusion 122 (see Figure 3(b)) in the vehicle width direction can be provided 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 inner side of the lens portion 110 in the vehicle width direction, or the light protrusion may be directly provided 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 to the bottom and the inner side of the lens portion 110 in the vehicle width direction, making it possible to form the trim line around the lens portion 110 with greater precision.

[0058] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these examples. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.
