Description

  The present invention relates to the technical field of an angle adjustment device for a vehicle which adjusts an angle of a body to be adjusted which is disposed in a disposition space of the housing.

  Generally, in each part such as a lamp provided in a vehicle, a camera, and a radar, an angle adjustment with respect to the housing is required, and the lamp, the camera, the radar, and the like also function as an angle adjustment device for a vehicle. For example, in the case of a vehicle headlamp which is one of the vehicle lamps, so-called aiming adjustment is performed to adjust the irradiation axis to a predetermined angle with respect to the housing as angle adjustment at the time of maintenance such as car inspection. .

  By performing the aiming adjustment, the light emitted from the light source of the vehicular headlamp is directed in the appropriate irradiation direction, and the generation of the illusionary light to the preceding vehicle, the oncoming vehicle or the like is prevented.

  On the other hand, a heat generator is often provided in a vehicle lamp or the like that functions as such a vehicle angle adjustment device. For example, in a vehicle lamp, heat is generated when the light source is turned on, and the light source or a circuit board on which the light source is mounted is used as the heat generating portion.

  Since the generation of such heat may affect the lighting of the light source, the proper driving state of the circuit board, and the like, it is desirable that the heat be dissipated.

  Therefore, some of the conventional vehicle angle adjustment devices, for example, vehicle headlights, are configured to transmit generated heat to the outside of the housing and to dissipate heat outside the housing (for example, a patent) Reference 1).

The unit having a light source disposed in the lamp chamber (arrangement space) is made rotatable relative to the housing by a ball joint structure, and at least one of the two aiming screws is rotated to support the unit with the spherical portion as a fulcrum The aiming adjustment is performed by being rotated with respect to it. Heat generated in a light source or the like which is a heat generating portion is transmitted from the ball joint structure to the housing and is released to the outside of the housing.

  Thus, since the heat generated in the heat generating portion is released to the outside of the housing, the temperature rise of the lamp chamber, which is the space inside the housing, is suppressed, high heat dissipation is ensured, and a good light source or circuit board etc. It becomes possible to secure the driving state.

In the state where the heat sink 34 is fastened to the heat transfer body 25, a gap is generated between the rear surface of the shaft 35 of the heat sink 34 and the front surface of the stopper nut 37.

  In the vehicle angle adjustment device 1 configured as described above, heat is generated from the light source 12 and the circuit board 11 which are heat generating parts when the light source 12 is lit. The generated heat is transmitted from the pedestal 10 to the connecting portion 25a of the heat transfer body 25, and is transmitted from the connecting portion 25a to the outer arrangement portion 25b. The heat transferred to the outer placement portion 25 b is transferred to the heat sink 34 and emitted from the heat sink 34 to the outside of the housing 2. Further, the heat transmitted to the outer placement portion 25 b is also transmitted to the fastening member 31 and the stopper nut 37, and is also released to the outside of the housing 2 from the fastening member 31 and the stopper nut 37.
