[0006] Problems to be solved by the invention

[0007] However, in the above-mentioned headlamp mounting structure, all brackets are fixed to the vehicle body behind the lamp body, so the center of gravity of the headlamp is located at a position closer to the front of the vehicle than the bracket. Therefore, there is room for improvement in the vibration resistance of the lamp when it is excited in the vertical direction.

[0008] The present invention has been made in view of the above-mentioned situation, and one of its exemplary objects is to provide a new lamp mounting structure capable of improving the vibration resistance of the lamp.

[0009] Means used to solve problems

[0010] In order to solve the above-mentioned problems, a lamp mounting structure of a certain embodiment of the present invention comprises: a vehicle lamp; a first member constituting a frame of a vehicle body; and a second member constituting an exterior of the vehicle body. The vehicle lamp comprises: a first mounting portion, which is mounted on the first member or the second member directly or via other components; a second mounting portion and a third mounting portion, which are mounted on the first member directly or via other components; and a fourth mounting portion, which is mounted on the second member directly or via other components. In addition, in the lamp mounting structure, when the vehicle lamp is viewed from above in a vertical direction, a lamp unit or an electronic control unit constituting the vehicle lamp is included in a quadrilateral area formed by connecting the respective mounting positions of the first mounting portion, the second mounting portion, the third mounting portion, and the fourth mounting portion.

[0011] According to this method, when the vehicle lamp is viewed from above in the vertical direction, a heavy unit such as a lamp unit or an electronic control unit is contained in a quadrilateral area formed by connecting the mounting positions of the four mounting parts. Therefore, even if the vehicle lamp is subjected to vertical vibration, the vehicle lamp as a whole is not easily tilted, and the vibration resistance is improved.

[0012] Another embodiment of the present invention is also a lamp mounting structure. The lamp mounting structure comprises: a vehicle lamp; a first member constituting a frame of a vehicle body; and a second member constituting an exterior of the vehicle body. The vehicle lamp comprises: a first mounting portion, which is mounted on the first member or the second member directly or via other components; a second mounting portion and a third mounting portion, which are mounted on the first member directly or via other components; and a fourth mounting portion, which is mounted on the second member directly or via other components. The lamp mounting structure is configured so that, when the vehicle lamp is viewed from above in a vertical direction, the center of gravity of the vehicle lamp is located in a quadrilateral region formed by connecting the respective mounting positions of the first mounting portion, the second mounting portion, the third mounting portion, and the fourth mounting portion.

[0013] According to this embodiment, when the vehicle lamp is viewed from above in the vertical direction, the center of gravity of the vehicle lamp is located in a quadrilateral area formed by connecting the mounting positions of the four mounting parts. Therefore, even if the vehicle lamp is subjected to vertical vibration, the vehicle lamp as a whole is not easily tilted, and the vibration resistance is improved.

[0014] Alternatively, in the vehicle lamp, a first mounting portion, a second mounting portion, and a third mounting portion are sequentially provided from the rear of the vehicle, and the fourth mounting portion is arranged closer to the front side of the vehicle than a line connecting the first mounting portion and the third mounting portion. Thus, a wide range of quadrilaterals including each unit and the center of gravity can be realized.

[0015] The second mounting portion may be arranged on the vehicle rear side relative to a line connecting the first mounting portion and the third mounting portion. Thus, a wide-range quadrilateral including each unit and the center of gravity can be realized.

[0016] Alternatively, the second member may be arranged to cover the vehicle lamp from above. Thus, the fourth mounting portion can be fixed to the second member above the vehicle lamp.

[0017] Alternatively, in the vehicle lamp, the first mounting portion is mounted from the side of the vehicle, the second mounting portion is mounted from the top of the vehicle, the third mounting portion is mounted from the top of the vehicle, and the fourth mounting portion is mounted from the front of the vehicle. Thus, the workability when mounting the vehicle lamp on the first component and the second component is improved.

[0018] Any combination of the above-mentioned components or forms of expressing the present invention in which the above-mentioned components are changed between manufacturing methods, lamps, lighting devices, light-emitting modules, light sources, etc. are also effective as forms of the present invention.

[0019] Effects of the Invention

[0020] According to the present invention, the vibration resistance of the lamp can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 Observed from the direction of arrow A Figure 1 A side view of the lamp mounting structure is shown.

[0023] Figure 3 yes Figure 1 A BB section view of the headlamp unit is shown. DETAILED DESCRIPTION

[0024] Hereinafter, the present invention will be described with reference to the accompanying drawings based on preferred embodiments. The same or equivalent components, members, and processes shown in the respective drawings are given the same reference numerals, and repeated descriptions are appropriately omitted. In addition, the embodiments do not limit the invention but are examples, and all the features and combinations thereof described in the embodiments are not the essential features and combinations thereof of the invention.

[0025] The vehicle lamp involved in this embodiment is a left and right headlamp arranged at the front of the vehicle. The following is a description of the lamp mounting structure for mounting the headlamp on the vehicle body. Vehicle lamps such as headlamps are large and heavy units as units mounted on the vehicle. Therefore, depending on the mounting position of the vehicle lamp on the vehicle body, the weight balance of the entire unit is unbalanced and is sometimes easily affected by the vibration of the vehicle. Therefore, the inventor of the present application has conducted in-depth research on the vehicle body parts and positions for mounting vehicle lamps, and thus came up with the present invention.

[0026] Figure 1 It is a plan view schematically showing a main part of the lamp mounting structure according to the present embodiment. Figure 2 Observed from the direction of arrow A Figure 1 A side view of the lamp mounting structure is shown. Figure 3 yes Figure 1 The BB section view of the headlamp unit is shown. Figure 1 , Figure 2 The vehicle light shown is the right side headlamp.

[0027] Figure 1The lamp mounting structure 10 shown in the figure includes a headlamp 12, a radiator core bracket 14 as a first member constituting a frame of a vehicle body, and a fender 16 as a second member constituting an exterior of the vehicle body. The first member may be a front cross member, and the second member may be other components around the fender.

[0028] like Figure 3 As shown, the headlamp 12 includes a lamp body 18 made of resin, a transparent cover 20 covering the opening of the lamp body 18, a lamp unit 22 disposed inside the lamp body 18, and an electronic control unit 24 fixed to the lower part of the lamp body 18. The lamp unit 22 is a unit using a light emitting element such as an LED as a light source.

[0029] The lamp body 18 constituting a part of the headlamp 12 has a first bracket 26 as a first mounting portion mounted on the fender 16, a second bracket 28 as a second mounting portion mounted on the radiator core bracket 14, a third bracket 30 as a third mounting portion, and a fourth bracket 32 ​​mounted on the fender 16. Each bracket provided at a predetermined position of the lamp body 18 is mounted to the radiator core bracket 14 and the fender 16 directly or via other components. Thus, the lamp body 18 is fixed to the vehicle body. For example, the second bracket 28 is fastened to the radiator core bracket 14 by bolts or the like. In addition, the fourth bracket 32 ​​is fastened by the fender bracket 34 fixed to the front end of the fender 16 and the bolt 36.

[0030] like Figure 1 As shown, in the lamp mounting structure 10 according to the present embodiment, when the headlamp 12 is viewed from above in the vertical direction, the lamp unit 22 and the electronic control unit 24 constituting the headlamp 12 are included in a quadrilateral region R formed by connecting the respective mounting positions of the first bracket 26, the second bracket 28, the third bracket 30, and the fourth bracket 32. In addition, the lamp unit 22 and the electronic control unit 24 may be included in the region R in their entirety or in part. In the case where a part of the lamp unit 22 and the electronic control unit 24 is included, it is sufficient that at least half of the weight of the lamp unit 22 and the electronic control unit 24 is included. In addition, the shape of the headlamp 12, the weight balance, and the arrangement of each bracket may be selected so that the center of gravity G of the headlamp 12 is included in the quadrilateral region R.

[0031] Thus, when the headlamp 12 is viewed from above in the vertical direction, heavy units such as the lamp unit 22 and the electronic control unit 24 are included in a quadrilateral region R formed by connecting the mounting positions of the four brackets. Therefore, even if vertical vibration is applied to the headlamp 12, the headlamp 12 as a whole is unlikely to tilt, and vibration resistance is improved.

[0032] In the headlight 12, from the rear of the vehicle ( Figure 1The first bracket 26, the second bracket 28 and the third bracket 30 are sequentially arranged from the upper side of the first bracket 26 to the upper side of the third bracket 30, and the fourth bracket 32 ​​is arranged on the vehicle front side (arrow F side) relative to the line L connecting the first bracket 26 and the third bracket 30. Thus, a wide range of quadrilaterals including each unit and the center of gravity G can be realized.

[0033] In addition, the second bracket 28 is disposed on the vehicle rear side (the side opposite to the arrow F) with respect to the line L. Thus, a wide-range quadrilateral including each unit and the center of gravity G can be realized.

[0034] like Figure 2 As shown in FIG. 1 , the fender panel 16 according to the present embodiment is arranged so as to cover the headlight 12 from above. Thus, the fourth bracket 32 ​​can be fixed to the fender panel 16 above the headlight 12 .

[0035] In the headlamp 12 according to the present embodiment, the first bracket 26 is installed in a direction from the side of the vehicle ( Figure 1 The second bracket 28 is installed in the direction of the arrow S1 from the top of the vehicle ( Figure 2 The third bracket 30 is installed in the direction of the arrow S2 from the top of the vehicle ( Figure 2 The fourth bracket 32 ​​is installed in the direction of the arrow S3 from the front of the vehicle ( Figure 1 Thus, the workability when the headlight 12 is mounted on the radiator core bracket 14 and the fender 16 is improved.
