[0006] Technical issues

[0007] However, in Patent Document 1, since the reflector is supported at three positions, namely the pivot part (ball joint) and the two adjusting screws (aiming screws), it is not possible to suppress the vibration of the reflector (vibration that occurs during vehicle operation, etc.), and there is a problem of reduced rigidity of resin parts involving the aiming reflector, etc.

[0008] The purpose of this invention is to provide a vehicle headlight accessory that can suppress the vibration of the reflector (such as vibration that occurs during vehicle operation).

[0009] The vehicle headlight accessory according to the present invention includes: a first retaining member that retains both a light source and a light control member that controls the light emitted by the light source; a second retaining member that retains the first retaining member so as to be tiltable in the up, down, left, and right directions; a vibration suppression unit that suppresses vibration of the first retaining member relative to the second retaining member; and the vibration suppression unit includes: a first portion disposed on the first retaining member; and a second portion disposed on the second retaining member, and suppresses vibration of the first retaining member relative to the second retaining member by abutting against the first portion which vibrates in the vibration direction of the first retaining member.

[0010] This configuration can suppress the vibration of the reflector (such as vibrations that occur during vehicle movement).

[0011] This is because a vibration suppression unit is provided to suppress the vibration of the first retaining member relative to the second retaining member.

[0012] The aforementioned vehicle light components may include: a pivot portion disposed on the first retaining member; a pivot retainer disposed in the second retaining member and rotatably retaining the pivot portion; a first adjusting screw that tilts the first retaining member in the left-right direction with the pivot portion as a fulcrum; and a second adjusting screw that tilts the first retaining member in the up-down direction with the pivot portion as a fulcrum.

[0013] Furthermore, in the aforementioned vehicle light accessories, the first part may be located near the first adjusting screw of the first retaining member.

[0014] Furthermore, in the aforementioned vehicle light accessories, the first part may be located near the second adjusting screw of the first retaining member.

[0015] Furthermore, in the aforementioned vehicle light accessory, the first part may be a first cylindrical part extending in a direction intersecting the vibration direction of the first retaining member, and the second part may be a slit portion having a U-shaped cross-section, the slit portion extending in a direction intersecting the vibration direction of the first retaining member, and the first cylindrical part may be arranged in the slit portion.

[0033] The following description of the vehicle lamp accessory 10 according to an embodiment of the present invention will be made with reference to the accompanying drawings. Throughout the drawings, the same parts are indicated by the same reference numerals, and redundant descriptions will be omitted.

[0034] Figure 1A This is a front view of headlight accessory 10, and Figure 1B This is the rear view. Figure 2 This is an exploded 3D view of the headlight accessory 10 (excluding external lenses, etc.). Figure 3A yes Figure 1B Cross-sectional view of IIIA-IIIA Figure 3B yes Figure 1B Cross-sectional view of IIIB-IIIB.

[0035] The headlight accessory 10 in this embodiment is a vehicle headlight and is mounted on the left and right sides of the front end of a vehicle such as an automobile (not shown). Since the headlight accessories 10 mounted on the right and left sides have a symmetrical configuration, the headlight accessory 10 mounted on the right side of the front end of the vehicle (facing forward) will be described as representative. For ease of explanation, the XYZ axes are defined as follows: Figure 1A As shown in the diagram. The X-axis extends in the longitudinal direction of the vehicle. The Y-axis extends in the width direction of the vehicle. The Z-axis extends in the vertical direction.

[0036] like Figure 1A and Figure 2 As shown, the headlight accessory 10 has a reflector 20 and a housing 30.

[0037] The reflector 20 holds both the light source 21 and the reflective surface 22 that controls the light emitted by the light source 21.

[0038] For example, light source 21 is a bulb light source such as a halogen bulb H4. Note that light source 21 can be a bulb light source other than a halogen bulb, such as an HID lamp. Light source 21 is inserted into bulb mounting holes H1 that penetrate the front and back of reflector 20 (see...). Figure 2 It is detachably mounted on the reflector 20 in a position relative to the reflector 20 (reflective surface 22) by a known fixing device.

[0039] The reflective surface 22 is a reflective surface that controls the light emitted by the light source 21 and is formed on the front side of the reflector 20. Specifically, the reflective surface 22 is configured as a reflective surface that combines multiple divided reflective regions (a so-called multi-reflector) such that a low-beam light distribution mode is formed when the low-beam filament of the light source 21 emits light, and a high-beam light distribution mode is formed when the high-beam filament emits light. The reflective surface 22 is formed, for example, by sequentially applying a base coating, aluminum deposition, and a top coating to a resin substrate (e.g., a BMC substrate).

[0040] The reflector 20 is attached to the housing 30 so that it can be tilted in the up, down, left and right directions (intended to be adjustable). Specifically, although not shown, the head 23a (spherical portion, hereinafter referred to as pivot portion 23a) of the pivot screw 23, which is attached to the back of the reflector 20, is rotatably held by the pivot retainer 31 attached to the front of the housing 30.

[0041] like Figure 3A As shown, a first adjusting screw N1, inserted into a through hole H2 formed in the housing 30, is threaded to a first aiming nut 24 fixed to the back of the reflector 20. Note that the first adjusting screw N1 is attached to the housing 30 so that it can rotate in the same position.

[0042] Figure 4This is a rear view of reflector 20. Figure 4 The balloon box B1 is Figure 4 An enlarged 3D view within rectangle b1. Figure 4 The balloon frame B2 is Figure 4 An enlarged 3D view within rectangle b2.

[0043] like Figure 4 As shown, the first aiming nut 24 is fixed to the back surface of the reflector 20 at a predetermined distance to the right of the pivot screw 23. The straight line L1 passing through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1) extends generally in the horizontal direction (Y direction).

[0044] like Figure 3B As shown, a second adjusting screw N2, inserted into a through-hole H3 formed in the housing 30, is threaded to a second aiming nut 25 fixed to the back of the reflector 20. Note that the second adjusting screw N2 is attached to the housing 30 so that it can rotate in the same position.

[0045] like Figure 4 As shown, the second aiming nut 25 is fixed to the rear surface of the reflector 20 at a predetermined downward distance from the pivot screw 23. Note that the reflector 20 is arranged in an inclined state due to the mounting space. Therefore, as... Figure 5 As shown, the straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (second adjusting screw N2) is relative to the vertical line L. V Tilt backward at an angle θ1. Angle θ1 is, for example, 5 degrees. Note that θ1 can also be 0 degrees. Figure 5 The straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (second adjusting screw N2) is shown relative to the vertical line L. V The backward tilt angle is θ1.

[0046] Next, the aiming operation will be described.

[0047] First, the aiming operation in the left and right directions will be described.

[0048] Figure 6A The aiming range (angles θ2 and θ3) in the left and right directions is shown.

[0049] Aiming in the left and right directions is performed by rotating the first adjusting screw N1 and changing the amount of threaded connection of the first adjusting screw N1 relative to the first aiming nut 24.

[0050] For example, suppose the first adjusting screw N1 is rotated such that the amount of threaded connection with the first aiming nut 24 is reduced. In this case, based on the amount of rotation of the first adjusting screw N1 (relative to the amount of threaded connection with the first aiming nut 24), the reflector 20 is positioned at an angle θ2 (see reference) with the pivot portion 23a as the fulcrum on the left side (towards the front of the vehicle) relative to the reference axis AX. Figure 6A The axis θ2 tilts (oscillates) around a straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (second adjusting screw N2). The reference axis AX extends in the X direction. θ2 is, for example, 2 degrees.

[0051] On the other hand, suppose the first adjusting screw N1 rotates, increasing the amount of threaded connection with the first aiming nut 24. In this case, based on the amount of rotation of the first adjusting screw N1 (relative to the amount of threaded connection with the first aiming nut 24), the reflector 20, with the pivot portion 23a as the fulcrum, is at an angle θ3 (see [reference]) on the right side (left side facing forward of the vehicle) relative to the reference axis AX. Figure 6A The axis is tilted (oscillated) around the straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (second adjusting screw N2). θ3 is, for example, 2 degrees.

[0052] As described above, aiming in the left and right directions is performed by rotating the first adjusting screw N1 and changing the amount of threaded connection of the first adjusting screw N1 relative to the first aiming nut 24.

[0053] Next, the aiming operation in the vertical direction will be described.

[0054] Figure 6B The aiming range (angles θ4 and θ5) in the vertical direction is shown.

[0055] Aiming in the up and down direction is performed by rotating the second adjusting screw N2 and changing the amount of threaded connection relative to the second aiming nut 25.

[0056] For example, suppose the second adjusting screw N2 rotates, reducing the amount of threaded connection with the second aiming nut 25. In this case, based on the amount of rotation of the second adjusting screw N2 (relative to the amount of threaded connection with the second aiming nut 25), the reflector 20, with its pivot portion 23a as the fulcrum, is at an angle θ4 on the upper side relative to the reference axis AX (see...). Figure 6B The axis is tilted (oscillated) around the straight line L1 that passes through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1). θ4 is, for example, 2 degrees.

[0057] On the other hand, suppose the second adjusting screw N2 rotates, increasing the amount of threaded connection with the second aiming nut 25. In this case, based on the amount of rotation of the second adjusting screw N2 (relative to the amount of threaded connection with the second aiming nut 25), the reflector 20, with its pivot portion 23a as the fulcrum, is at an angle θ5 on the lower side relative to the reference axis AX (see...). Figure 6B The axis is tilted (oscillated) around the straight line L1 that passes through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1). θ5 is, for example, 2 degrees.

[0058] As described above, aiming in the vertical direction is performed by rotating the second adjusting screw N2 and changing the amount of threaded connection of the second adjusting screw N2 relative to the second aiming nut 25.

[0059] Next, the configuration for suppressing the vibration of the reflector 20 (the up-and-down vibration in Figure 3) (the configuration of the vibration suppression unit) will be described. The first cylindrical portion 26, the second cylindrical portion 27, the first slit portion 32, and the second slit portion 33 constitute the vibration suppression unit (slider mechanism).

[0060] like Figure 4 As shown, the first cylindrical portion 26 and the second cylindrical portion 27 are disposed on the back side of the reflector 20.

[0061] The first cylindrical portion 26 is disposed on a straight line L1 passing through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1), and is disposed near the first adjusting screw N1. The first cylindrical portion 26 extends in a direction intersecting (e.g., orthogonal) to the vibration direction (vertical direction) of the reflector 20 (e.g., the Y direction). The first cylindrical portion 26 is supported by support portions 28a, 28b, the two ends of which extend axially from the back surface of the reflector 20 (see...). Figure 4 (Balloon frame B1 in the diagram). Note that the first cylindrical portion 26, the support portions 28a, 28b, and the reflector 20 are integrally formed. Note that the first cylindrical portion 26 may have a complete or incomplete cylindrical shape. In this embodiment, for ease of molding (relative to the draft angle), the first cylindrical portion 26 is not a perfect cylindrical shape, but an incomplete cylindrical shape.

[0062] Figure 7A yes Figure 1B Sectional view of VIIA-VIIA.

[0063] like Figure 7A As shown, with the reflector 20 attached to the housing 30 to be tilted in the up, down, left and right directions, the first cylindrical portion 26 is arranged in the first slit portion 32 provided in the housing 30.

[0064] The first slit portion 32 includes an upper portion 32a and a lower portion 32b extending in a direction (e.g., orthogonal) relative to the vibration direction (up and down direction) of the reflector 20, and is a portion having a U-shaped cross section.

[0065] The slit width W1 of the first slit portion 32 is the distance between the upper portion 32a and the lower portion 32b. See also Figure 7A The value is considered to be such that it is smaller than the amount of movement (the amount of movement in the Z direction) of the first cylindrical portion 26 due to the vibration (vertical vibration) of the reflector 20.

[0066] Furthermore, the slit depth D1 of the first slit portion 32 (see...) Figure 7A The value is considered to be such that even if the reflector 20 is tilted by aiming in the left and right directions with the pivot portion 23a as the fulcrum around the straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (the second adjusting screw N2), the first cylindrical portion 26 moves within the first slit portion 32 (that is, so that the first cylindrical portion 26 does not move out of the first slit portion 32).

[0067] like Figure 4 As shown, the second cylindrical portion 27 is disposed near the second adjusting screw N2. Like the first cylindrical portion 26, the second cylindrical portion 27 extends in a direction intersecting (e.g., orthogonal) to the vibration direction (vertical direction) of the reflector 20 (e.g., the Y direction). The second cylindrical portion 27 is supported by support portions 29a, 29b, the two ends of which extend axially from the back surface of the reflector 20 (see Figure 29a). Figure 4 (Balloon frame B2 in the image). Note that the second cylindrical portion 27, support portions 29a, 29b, and reflector 20 are integrally formed. Note that the second cylindrical portion 27 may have a complete or incomplete cylindrical shape. In this embodiment, for ease of molding (relative to the draft angle), the second cylindrical portion 27 is not a perfect cylindrical shape, but an incomplete cylindrical shape.

[0068] Figure 7B yes Figure 1B Sectional view of VIIB-VIIB.

[0069] like Figure 7B As shown, with the reflector 20 attached to the housing 30 to be tilted in the up, down, left and right directions, the second cylindrical portion 27 is arranged in the second slit portion 33 provided in the housing 30.

[0070] The second slit portion 33 includes an upper portion 33a and a lower portion 33b extending in a direction (e.g., orthogonal) relative to the vibration direction (up and down direction) of the reflector 20, and is a portion having a U-shaped cross section.

[0071] The slit width W2 of the second slit portion 33 (the distance between the upper portion 33a and the lower portion 33b). See also Figure 7B The value is considered to be such that it is smaller than the amount of movement (the amount of movement in the Z direction) of the second cylindrical portion 27 due to the vibration (vertical vibration) of the reflector 20.

[0072] Furthermore, the slit depth D2 of the second slit portion 33 (see...) Figure 7B The value is considered to be such that even if the reflector 20 is tilted about a straight line L1 passing through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1) by aiming in the up-down direction, the second cylindrical portion 27 moves within the second slit portion 33 (that is, the second cylindrical portion 27 does not move out of the second slit portion 33). However, in this embodiment, for ease of molding (relative to the draft angle), the upper portion 33a of the second slit portion 33 is shorter than the lower portion 33b. Note that the upper portion 33a of the second slit portion 33 can be shorter than the lower portion 33b because the vibration (up-down direction vibration) on the side of the second cylindrical portion 27 of the reflector 20 is smaller than the vibration (up-down direction vibration) on the side of the first cylindrical portion 26, and the second cylindrical portion 27 and the second slit portion 33 are auxiliary vibration measures.

[0073] Next, the vibration suppression operation will be described.

[0074] Figure 8 and Figure 9 This is a diagram used to illustrate vibration suppression operation.

[0075] exist Figure 8 In this context, "0 degrees" indicates the positional relationship between the first cylindrical portion 26 and the first slit portion 32 located in the housing 30 in the reference state before aiming. Figure 8 In this context, "2 degrees" refers to an angle θ2 relative to the reference axis AX, directed to the left (towards the front left of the vehicle), around a straight line L2 passing through the pivot portion 23a and the second aiming nut 25 (second adjusting screw N2) with the reflector 20 as the fulcrum. (See also: [link to relevant documentation]). Figure 6A The positional relationship between the first cylindrical portion 26 and the first slit portion 32 disposed in the housing 30 in a tilted (swinging) state. Figure 8In this context, "-2 degrees" indicates that the reflector 20, with pivot portion 23a as the fulcrum, revolves around a straight line L2 passing through pivot portion 23a and the second aiming nut 25 (second adjusting screw N2), at an angle θ3 to the right (towards the front right of the vehicle) relative to the reference axis AX (see [reference]). Figure 6A The positional relationship between the first cylindrical portion 26 and the first slit portion 32 disposed in the housing 30 in a tilted (swinging) state.

[0076] Reference Figure 8 It can be seen that when aiming in the left-right direction within angles θ2 and θ3, the first cylindrical portion 26 moves within the first slit portion 32 (that is, the first cylindrical portion 26 does not move outside the first slit portion 32). In other words, when aiming in the left-right direction within angles θ2 and θ3, the first cylindrical portion 26 moves between the upper portion 32a and the lower portion 32b of the first slit portion 32.

[0077] Therefore, when the reflector 20 (first cylindrical portion 26) vibrates (vibrates in the vertical direction), the vibrating first cylindrical portion 26 abuts against the first slit portion 32 (upper portion 32a or lower portion 32b). This suppresses the vibration (vertical vibration) of the reflector 20 (first cylindrical portion 26).

[0078] exist Figure 9 In this context, "0 degrees" indicates the positional relationship between the second cylindrical portion 27 and the second slit portion 33 within the housing 30 in the reference state before aiming. "2 degrees" indicates the upward angle θ4 relative to the reference axis AX of the reflector 20 about a straight line L1 passing through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1) with the pivot portion 23a as the fulcrum. (See [reference]). Figure 6B In a tilted (swinging) state, the positional relationship between the second cylindrical portion 27 and the second slit portion 33 disposed in the housing 30. "-2 degrees" indicates that the reflector 20, with the pivot portion 23a as a fulcrum, revolves around a straight line L1 passing through the pivot portion 23a and the first aiming nut 24 (first adjusting screw N1) at an angle θ5 downward relative to the reference axis AX (see...). Figure 6A The positional relationship between the second cylindrical portion 27 and the second slit portion 33 provided in the housing 30 in a tilted (swinging) state.

[0079] Reference Figure 9It can be seen that when aiming in the vertical direction within angles θ4 and θ5, the second cylindrical portion 27 moves within the second slit portion 33 (that is, the second cylindrical portion 27 does not move outside the second slit portion 33). In other words, when aiming in the vertical direction within angles θ4 and θ5, the second cylindrical portion 27 moves while sandwiched between the upper portion 33a and the lower portion 33b of the second slit portion 33.

[0080] Therefore, when the reflector 20 (second cylindrical portion 27) vibrates (vibrates in the vertical direction), the vibrating second cylindrical portion 27 abuts against the second slit portion 33 (upper portion 33a or lower portion 33b). This suppresses the vibration (vertical vibration) of the reflector 20 (second cylindrical portion 27).

[0081] As described above, according to this embodiment, vibrations of the reflector 20 (such as vertical vibrations that occur when the vehicle is moving) can be suppressed. As a result, the rigidity of resin components involving the aiming reflector, etc., is improved.

[0082] This is due to the vibration suppression unit (slider mechanism) that suppresses the vibration of the reflector 20 relative to the housing 30 (vibration in the vertical direction). Specifically, a first cylindrical portion 26, a second cylindrical portion 27, a first slit portion 32, and a second slit portion 33 are included. The first cylindrical portion 26 is arranged within the first slit portion 32, and the second cylindrical portion 27 is arranged within the second slit portion 33. Although there is no significant movement (almost no movement) during vertical vibration, deformation occurs in the first aiming nut 24 and the second aiming nut 25. Conversely, according to this embodiment, due to the vibration suppression unit (slider mechanism), the first aiming nut 24, the second aiming nut 25, etc., do not move unnecessarily, thus minimizing deformation. As a result, damage to the first aiming nut 24 and the second aiming nut 25 is suppressed.

[0083] Next, a variant will be described.

[0084] In the above embodiments, an example is described using a reflector 20 that holds both the light source 21 (bulb light source) and the reflective surface 22 that controls the light emitted by the light source 21 as the first holding member, but this is not limited to the above description.

[0085] For example, as the first holding member, a mounting ring 40 (also called a bracket) can be used to hold both the light source (a semiconductor light-emitting element such as an LED) and the optical system (near beam unit and far beam unit) such as a lens that controls the light emitted by the light source.

[0086] Figure 10This is an example of a headlight accessory 10A using a mounting ring 40, which holds three lenses 41, 42, and 43 that control the light emitted by the light source.

[0087] Furthermore, in the above embodiments, when the vibration of the reflector 20 (vibration in the vertical direction) is suppressed, an example has been described in which a first cylindrical portion 26 (and a second cylindrical portion 27) extending in a direction intersecting (e.g., orthogonally) with respect to the vibration direction (e.g., the Y direction) and a first slit portion 32 (and a second slit portion 33) extending in a direction intersecting (e.g., orthogonally) with respect to the vibration direction (e.g., the Y direction) and having a U-shaped cross section are used as vibration suppression units (slider mechanisms), but this is not limited to what has been described above.

[0088] For example, when the vibration of reflector 20 (vibration in the left-right direction) is suppressed, a cylindrical portion extending in a direction intersecting (e.g., orthogonally) with respect to the vibration direction (e.g., the Z direction) and a slit portion extending in a direction intersecting (e.g., orthogonally) with respect to the vibration direction (e.g., the Z direction) and having a U-shaped cross-section can be used as a vibration suppression unit (slider mechanism) (see...). Figure 11 ). Figure 11 yes Figure 10 The cross section of XI-XI within the rectangle B3 is an example of a cylindrical portion 26A extending in a direction (e.g., orthogonal) relative to the vibration direction (vibration in the left-right direction) of the reflector 20, and a slit portion 32A extending in a direction (e.g., orthogonal) relative to the vibration direction and having a U-shaped cross section. Figure 11 yes Figure 10 The cross section of CC within rectangle B3.

[0089] In the above embodiments, an example has been described in which the first cylindrical portion 26 (and the second cylindrical portion 27) are integrally formed with the reflector 20, but this is not limited to the above description. For example, the first cylindrical portion 26 (and the second cylindrical portion 27) may be configured as a component separate from the reflector 20 and subsequently attached to the reflector 20.

[0090] The vehicle lighting accessories of the present invention can also be applied to LED headlights (projector type, reflector type, direct projection type).

[0091] The values ​​shown in each of the above embodiments are given by way of example, and it is obvious that different values ​​can be used instead.

[0092] Each of the above embodiments is merely an example in each aspect. The invention should not be limited to the description of each of the above embodiments. The invention can be implemented in various other ways without departing from the spirit or essential characteristics of the invention.

[0093] This application is based on and claims the priority of Japanese Patent Application No. 2021-051032, filed on March 25, 2021, the disclosure of which is incorporated herein by reference in its entirety.
