Identical or similar elements, members and processes shown in each of the drawings are represented by like or similar reference numerals and the repetition of their description will be omitted as appropriate. In addition, the embodiment is explanatory and is not intended to limit the present invention. It will be appreciated that all the features and combinations thereof described in the embodiment are not necessarily considered an essential part of the present invention. Fig. 1 is a schematic view for explaining the mounting position of a tilt sensor housing according to an exemplary embodiment. An inclination sensor housed in the tilt sensor housing is included in a trim ECU 1. The trim ECU 1 is installed for example near the dashboard of the vehicle body 300. D on the other hand, the mounting position of the attitude ECU 1 or the inclination sensor housing case is not particularly limited. For example, the attitude ECU 1 or the inclination sensor housing can be provided in a headlight unit 210. When asked to implement automatic attitude control from a lighting switch or the like mounted, for example, in a vehicle, the attitude ECU 1 begins to implement the automatic attitude control. In the automatic attitude control, the attitude ECU 1 generates information regarding the pitch angle in the pitch direction of a vehicle using the output value of the inclination sensor. The attitude ECU 1 then controls a attitude actuator 226 (see FIG. 2) using the information obtained and adjusts the optical axis of a lamp unit 10 (see FIG. that vehicle lamp mounted on the headlight unit 210 at an angle corresponding to the vehicle posture. In this way, the automatic attitude control for real-time setting of the attitude of the lamp unit 10 based on the vehicle posture is performed. As a result, it is possible to optimally adjust the range of range of the radiation light forward even when the posture of the vehicle is changed.
    [0005] Figure 2 is a schematic vertical sectional view of the headlight unit including the vehicle lamp. The headlight unit 210 has a structure in which a pair of headlight units are arranged, one by one, on the left and right sides in the vehicle width direction of a vehicle. The pair of headlight units is formed in a bilaterally symmetrical manner. A right headlight unit 210R has a structure substantially identical to that of a left headlight unit 210L. Accordingly, in the following, the structure of the right headlight unit 210R will be described.
    [0006] The headlight unit 210 includes a lamp body 212 having an opening portion on the front side of a vehicle and a transparent cover 214 covering the opening portion. The lamp body 212 has a removable cover 212a on the rear side of the vehicle. A lamp chamber 216 is formed by the lamp body 212 and the transparent cover 214. The lamp unit 10 is disposed in the lamp chamber 216. A lamp holder 218 is connected to the lamp unit 10. lamp holder 218 comprises a pivoting mechanism 218a which constitutes the center of pivoting in the vertical direction and the lateral direction of the lamp unit 10. The lamp holder 218 is screwed with a sight adjustment screw 220 supported on the A rotational shaft 222a of a pivot actuator 222 is attached to the lower surface of the lamp unit 10. The pivot actuator 222 is attached to a unit support. 224. The attitude actuating device 226 is connected to the unit support 224. The attitude actuating device 226 is configured for example by a motor or the like which extends and retracts a rod 226a in the directions indicated by fl When the rod 226a is extended and retracted in the directions indicated by the arrows M, N, the lamp unit 10 moves into a backward inclination position and a tilting posture towards the before. In this way, it is possible to adjust the attitude so that the attitude angle of the optical axis 0 of the lamp unit 10 is downward and upward. The lamp unit 10 includes a masking mechanism 18 having a rotating mask 12, a light source 14, a lamp housing 17 for supporting a reflector 16 on its inner wall and a projection lens 20. As a source 14, an incandescent lamp, a halogen lamp, a discharge lamp, an LED and the like can be used. At least a portion of the reflector 16 has an elliptical spherical shape. The reflector 16 reflects the light emitted by the light source 14. The light emitted by the light source 14 and reflected by the reflector 16 is partially guided towards the projection lens 20 via the rotary mask 12. The rotary mask 12 is a cylindrical member that can be rotated about a rotation shaft 12a. The rotary mask 12 has a cutting portion and a plurality of mask plates (not shown). A cutting portion or the mask plates is / are displaced on the optical axis 0, so as to form a predetermined light distribution pattern. The projection lens 20 is a plano-convex aspherical lens. The projection lens 20 is adapted to project the image of a light source formed on a rear focal plane, as an inverted image, on a virtual vertical screen located in front of the lamp. A tilt sensor housing case according to an exemplary embodiment will then be described in detail. Fig. 3 is an exploded perspective view showing a schematic structure of a trim ECU including the tilt sensor housing housing according to the exemplary embodiment. Figure 4 is a perspective view showing a schematic structure of the attitude ECU viewed obliquely from below. Figure 5 is a schematic view of the plate ECU viewed from the side. In the following description, for convenience, the normal direction of the sidewall 116 refers to the lateral direction of a tilt sensor housing housing 100. The direction parallel to the main surface of the sensor housing housing inclination 100 and to the side walls 116, i.e., the direction of insertion of the substrate 400, refers to the longitudinal direction of the tilt sensor housing 100. The normal direction of the main surface of the tilt sensor housing housing 100 refers to the vertical direction of the tilt sensor housing housing 100.
    [0007] The attitude ECU 1 comprises the tilt sensor housing 100, a tilt sensor 410, the substrate 400 and a CPU 412 as the controller. The inclination sensor 410 is mounted on the substrate 400. A predetermined wiring pattern is provided in the main surface of the substrate 400. On the substrate 400, the inclination sensor 410, the CPU 412, is mounted. contain various control programs, a RAM used as a work area to store data or run a program, an input interface (input I / F) to monitor the input voltage of the substrate 400, enter a signal from various switches or the like and communicating therewith, an output interface (output TIF) for outputting a control signal to the attitude actuating device 226 and performing communication therewith , and a memory or the like. In addition, a connector 414 is mounted on the substrate 400. The connector 414 is adapted to input a vehicle speed signal and a lighting switching signal and the like from a vehicle or to output the information generated to a vehicle. outside. In the present embodiment, the substrate 400 has a rectangular shape, in plan view. The connector 414 is provided on one side of the substrate 400. The inclination sensor 410 is a sensor for calculating the angle of inclination of the vehicle. In the present embodiment, the inclination sensor 410 is configured by means of an acceleration sensor. The CPU 412 generates information on the tilt angle of the vehicle using the output value of the tilt sensor 410. The CPU 412 controls the adjustment of the optical axis of the vehicle unit 10 using the information generated. In the present embodiment, the attitude ECU 1 has an integrated sensor-CPU structure such that the inclination sensor 410 and the CPU 412 are mounted on the same substrate 400. The present invention is not particularly limited. For example, the attitude ECU 1 may have a structure in which the CPU 412 is mounted on a separate substrate different from that of the inclination sensor 410. That is, the attitude ECU 1 may have a structure in which the CPU 412 is a separately configured component of a tilt sensor device. The tilt sensor device is here configured by the tilt sensor housing housing 100 and the substrate 400 on which the tilt sensor 410 is mounted.
    [0008] The tilt sensor housing housing 100 has a rectangular rectangular parallelepiped shape. The tilt sensor housing housing 100 has a main body portion 110 and a lid portion 150. The main body portion 110 is a container-shaped member having a housing space 112 for the substrate 400. The main body portion 110 has an opening portion 114 for inserting the substrate 400 into the housing space 112. The opening portion 114 is provided on a surface of the main body portion corresponding to a side wall of the housing. In addition, the main body portion 110 has guide rails 118 provided on the inner surfaces of two sidewalls 116. The two sidewalls 116 intersect the extension direction of the inner portion. opening 114 and are opposed to each other. The guide rails 118 extend in the direction of insertion of the substrate 400 (direction indicated by an arrow A in FIG. 3, in other words, the longitudinal direction). The substrate 400 is inserted along the guide rails 118 into the housing space 112 through the opening portion 114 from an end opposite the connector 414. An edge (two edges extending parallel to the direction of insertion of the substrate 400 and opposed to each other) of the substrate 400 is supported by the guide rails 118 in a state where the substrate 400 is housed in the housing space 112. Second engagement portions 120 are provided in positions near the opening portion 114 in the outer surfaces of two sidewalls 116 of the main body portion 110. The second engaging portions 120 are engaged with the first engagement portions. 154 of the cover portion 150. In the present embodiment, the second engagement portion 120 is configured by an engagement protrusion. The engagement protrusion protrudes toward the first engaging portion from the outer surface of the sidewall 116 to a state where the cover portion 150 is mounted on the main body portion 110. Support socket 122 is provided in the main surface of main body portion 110. One end of ECU support 600 (see Fig. 6) engages with support engaging portion 122 and the Another end of the ECU 600 support is engaged with the vehicle body. In this manner, the tilt sensor housing case 100 and thus the seat ECU 1 are mounted on the vehicle body. In addition, the main body portion 110 includes first protuberances 124 and second protuberances 126, which are provided to prevent damage to the first engaging portion 154. The first protuberances 124 and the second protuberances 126 are respectively provided. in the vicinity of each of the second engagement portions 120. The shape or arrangement or the like of the first protuberances 124 and 10 of the second protuberances 126 will be described in detail later. The lid portion 150 is an element for closing the opening portion 114 of the main body portion 110. The lid portion 150 includes a wall portion 152 and two first engaging portions 154. The wall portion 152 is fitted into the opening portion 114 and is one of the side walls of the tilt sensor housing 100. In addition, the wall portion 152 has an opening portion 156 to allow the connector 414 substrate 400 housed in the main body portion 110 protruding outwardly. The first engagement portions 154 are provided at both ends of the wall portion 152. Each of the first two engagement portions 154 extends along the outer surface of the body portion side wall 116. 110 in a state where the cover portion 150 is mounted on the main body portion 110. Accordingly, the side wall 116 and the first engagement portions 154 are opposed to each other at both the left-hand side and right of the tilt sensor housing housing 100 between which is inserted the opening portion 156. In the present embodiment, the first engagement portion 154 is configured by an engagement jaw. The engagement jaw is configured by a first arm portion 154a, a second arm portion 154b, and a connecting portion 154c. Each of the first arm portion 154a and the second arm portion 154b extends in the longitudinal direction, i.e. in the direction of insertion of the substrate 400. In addition, both arm portions 154a and 154b are separated from each other in the vertical direction, i.e. in the direction perpendicular to the direction of insertion of the substrate 400. The connecting portion 154c connects the leading ends of the first arm portion 154a and second arm portion 154b. Accordingly, the first engagement portion 154 configured by the engagement jaw includes an aperture portion that is formed by one end of the wall portion 152, the first arm portion 154a, the second portion of the arm 154b and the connecting portion 154c. The second engagement portion 120 configured by an engagement protrusion is fitted into the opening portion. After housing the substrate 400 in the housing space 112 of the main body portion 110, the lid portion 150 is fitted into the opening portion 114. The lid portion 150 is mounted on the main body portion 110 by a snap coupling using the resiliency of the cover portion 150. In addition, along with the snap coupling of the cover portion 150 to the main body portion 110, the first engagement portion 154 is engaged with the second engaging portion 120 and thus, the lid portion 150 is locked to the main body portion 110. Specifically, the lid portion 150 is aligned with the main body portion 110. so that the connector 414 is inserted through the opening portion 156. Thus, the lid portion 152 is pushed so as to move closer to the opening portion 114. When the lid portion 150 is in to the main body portion 110, the connecting portion 154c of the first engaging portion 154 abuts against the second engaging portion 120. In this state, when the lid portion 150 is further urged towards the main body portion 110, the connecting portion 154c of the first engaging portion 154 is pushed outward by the second engagement portion 120. In this manner, the lid portion 150 is deformed resiliently and two first engagement portions 154 are moved in a direction away from each other. When the lid portion 150 is further biased toward the main body portion 110 and thus the wall portion 152 is fitted into the opening portion 114, the connecting portion 154c is in a superposition state on the second portion 120. Thus, the support of the connecting portion 154c by the second engaging portion 120 is released, so that the cover portion 150 returns, by its elasticity, in the state preceding the displacement. In this manner, the second engaging portion 120 is fitted into an opening portion which is formed by one end of the wall portion 152, the first arm portion 154a, the second arm portion 154b, and the connection 154c. Accordingly, the engagement jaw of the first engagement portion 154 and the engagement protrusion of the second engagement portion 120 are engaged with each other by engagement with each other. irregular shape. The connector 414 is exposed to the outside of the housing from the opening portion 156. The connector 414 is connected to a beam 500 (see Fig. 6) for connecting the substrate 400 to an external device.
    [0009] In a state where the cover portion 150 is mounted on the main body portion 110, the first protuberances 124 and the second protuberances 126 are arranged in a state of interposition of the first engagement portions 154 therebetween. That is, the first protuberances 124 are disposed on the main surface of the tilt sensor housing 100 and the second protuberances 126 are disposed on the other major surface (in the present embodiment a surface where is provided the support engaging portion 122) thereof. In addition, the first protuberances 124 are provided on corners where a major surface of the main body portion 110, the side wall 116 and the wall portion 152 of the lid portion 150 are in contact with each other. Similarly, the second protuberances 126 are provided on corners where the other major surface of the main body portion 110, the side wall 116 and the wall portion 152 are in contact with each other.
    [0010] The first protuberances 124 and the second protuberance 126 project outwardly from the first engaging portion 154 in a direction of overlap of the outer surface of the side wall 116 and the first engaging portion 154, c '. that is, in the lateral direction of the tilt sensor housing housing 100.
    [0011] In addition, the end surfaces on the side of the cover portion 150 of the first protuberances 124 and the second protuberances 126 are located at the same level as the wall portion 152 of the cover portion 150. In other words, the first protuberances 124 are provided on corners so as to cover the first engagement portions 154, viewed from the normal direction of the main surface of the tilt sensor housing 100. At the corners, a major surface of the main body portion 110, the side wall 116 and the wall portion 152 are in contact with each other. Similarly, the second protuberances 126 are provided at the corners so as to cover the first engaging portions 154, seen from the normal direction of the main surface of the tilt sensor housing 100. At the corners, the other main surface of the main body portion 110, the side wall 116 and the wall portion 152 are in contact with each other. In this manner, the first protuberances 124 and the second protuberances 126 can prevent the first engagement portion 154 from directly colliding with the ground or the like, even when the attitude ECU 1 is dropped during the mounting the attitude ECU 1 on the vehicle body 300. To protect from the externally applied shock the substrate 400 housed in the tilt sensor housing housing 100 or the tilt sensor 410 and the CPU 412, which are mounted on the substrate 400, the tilt sensor housing housing 100 is preferably formed of a material having a relatively high rigidity, such as PBT (polybutyrene terephthalate). Further, the deformation of the tilt sensor housing housing 100 can be suppressed when the tilt sensor housing housing 100 is formed of the material having high rigidity. In this way, the deformation of the substrate 400 and the posture modification of the tilt sensor 410 due to deformation can be suppressed. Since the posture of the tilt sensor 410 can be kept stable, it is possible to improve the accuracy of the automatic attitude control. On the other hand, in the case where it is formed of a material having high rigidity, the impact resistance of the tilt sensor housing housing 100 tends to decrease. As a result, the tilt sensor housing housing 100 can be easily broken by shock or the like when dropped. In particular, since the first engagement portions 154 of the cover portion 150 are provided at the corners of the tilt sensor housing housing 100, the first engagement portions 154 directly collide with the ground. or the like and have a tendency to break easily when the tilt sensor housing 100 is dropped. As a method of preventing breakage of the first engaging portions 154, it is contemplated to improve the resistance to impacting by increasing the thickness of the first engagement portions 154. However, since the first engagement portions 154 and the second engagement portions 120 are engaged with each other by engagement with each other. of irregular shape, it is difficult to mount the cover portion 150 on the main body portion 110 as the thickness of the first engagement portions 154 is increased. Otherwise, the first engagement portions 154 are easily damaged during irregular shaping. In contrast, in the present embodiment, the first protuberances 124 and the second protuberances 126 are provided in a state of interposition of the first engaging portions 154 therebetween. In this way, the first engagement portions 154 can be prevented from directly colliding with the ground or the like when the tilt sensor housing housing 100 falls. As a result, it is possible to prevent damage to the first engagement portions 154 without sacrificing easy mounting of the cover portion 150 to the main body portion 110. Accordingly, the sensor housing housing of Tilt 100 may be less damaged. To protect the first engagement portions 154, the first protuberances 124 and the second protuberances 126 may project at least up to the same height as the first engagement portions 154 in the lateral direction of the sensor housing. The first engaging portions 154 can here be more securely protected when the first protuberances 124 and the second protuberances 126 project outwardly from the first engaging portions 154. This applies also at the end surfaces of the side of the cover portion 150 of the first protuberances 124 and the second protuberances 126.
    [0012] That is, the first engagement portions 154 may be more securely protected when these end surfaces project outwardly from the wall portion 152. In addition, in the first protuberances 124 and the second protuberances 126, the outwardly protruding portions of the first engaging portions 154 and the outwardly projecting portions of the wall portion 152 may be used as the crush margin. That is, when the attitude ECU 1 is dropped and thus the first protuberances 124 and / or the second protuberances 126 collide with the ground, the portions of the first protuberances 124 and / or or second protuberances 126, which protrude outwards, are deformed. Consequently, it is possible to be informed of the presence or absence of the fall of the attitude ECU 1 by visually confirming whether the first protuberances 124 and the second protuberances 126 are deformed or not. Further, as shown in Fig. 5, the substrate 400 is disposed in a position offset from the center of the main body portion 110 in the vertical direction of the tilt sensor housing housing 100. That is, that is, the guide rails 118 are disposed in a position offset from the center in the vertical direction of the main body portion 110. For example, to provide a housing space for the inclination sensor 410 or the like which is mounted on the substrate 400, the substrate 400 and the guide rails 118 are arranged to be offset from the center, so that the space on the substrate surface side for mounting the inclination sensor 410 or the like is expanded. In addition, the first engaging portion 154 has a shape such that the second arm portion 154b close to the guide rail 118 is thicker than the first arm portion 154a. When the attitude ECU 1 is dropped and collides with the ground or the like, the substrate 400 can press the cover portion 150 from the inside. At this time, a force applied to the cover portion 150 by the support of the substrate 400 tends to be concentrated in the first engaging portion 154. In particular, there is a tendency that the force is concentrated in the second arm portion 154b closer to the substrate 400. As a result, the second arm portion 154b is formed to be thicker than the first arm portion 154a, so that the resistance of the second arm portion 154b is increased. . As a result, it is possible to more safely prevent damage to the first engagement portion 154.
    [0013] A beam attachment structure which connects the substrate 400 and an external device will then be described. Figure 6 is a schematic view showing a beam attachment structure. The ECU support 600 includes an ECU mounting portion 602, a vehicle body attachment portion 604 and a beam attachment portion 606. The attitude ECU 1 is attached to the mounting portion of the ECU 602 of the ECU 600 support through the support engaging portion 122 (see Fig. 4). The vehicle body attachment portion 604 is attached to the vehicle body 300 by a fastener 610, such as screws. In the beam 500 connected to the connector 414, a medial portion between the substrate 400 and the external device is attached to the beam attachment portion 606 of the ECU support 600 by a beam mount 620. For example, in a process of assembly or repair process of a vehicle, there is a possibility that a worker hangs his hand or a tool or the like beam 500. In this case, a force F in a direction pulled to the outer device is applied 500 beam 500.
