Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a camera mounting structure, and more particularly to a camera mounting structure for helping to secure a field of view in front of a vehicle.
[0002]
[Prior art]
When driving a car, a blind spot may occur around the vehicle. For example, in a sedan type passenger car, it is difficult to visually confirm the surroundings of a front bumper and a rear bumper. In view of this, a system has been developed that assists in securing a front view and a rear view by installing a CCD camera in front of and behind the vehicle and displaying images from the camera on a screen of a navigation system in the vehicle interior.
[0003]
Japanese Patent Application Laid-Open No. 2001-58543 introduces a camera mounting structure used in this type of system. FIG. 5 shows a cross-sectional view of the camera mounting structure described in the publication. The emblem 100 is disposed substantially at the center in the vehicle width direction at the rear end of the vehicle. A rear camera 101 is fixed to the back surface of the emblem 100. A rack 102 is erected from the back surface of the emblem 100. The rack 102 extends in an arc shape toward the in-vehicle direction. The upper end of the emblem 100 is pivoted on the vehicle via a swing shaft 103. A case 104 is disposed inside the emblem 100. The case 104 has a box shape and includes an opening 105 in the direction of the emblem 100. A driving device 108 is disposed above the case 104. A drive shaft 107 to which the pinion 106 is fixed is disposed in the drive device 108. The teeth of the pinion 106 and the teeth of the rack 102 are meshed with each other.
[0004]
When using the camera, the rear camera 101 is projected from the rear end of the vehicle. That is, the driving force of the driving device 108 is transmitted to the rack 102 via the driving shaft 107 and the pinion 106. With this driving force, the rack 102 is pushed rearward of the vehicle. The emblem 100 and the rear camera 101 that are fixed to the rack 102 also swing backward about the swing shaft 103. In this way, the rear camera 101 is projected from the rear end of the vehicle.
[0005]
[Problems to be solved by the invention]
By the way, the space restriction is small at the rear end of the vehicle. For this reason, it is easy to dispose the driving device 108 above the case 104 when imaging the rear of the vehicle as in the camera mounting structure described in the publication. However, the emblem at the front end of the vehicle is often arranged at the center of the front grill. For this reason, when the drive device is arranged above the case, the drive device is exposed from the gaps in the front grille and looks bad. In order to hide the drive device, it is necessary to enlarge the emblem. However, when the emblem is enlarged, the design balance between the emblem and the front grill may be deteriorated. Further, when the emblem is enlarged, the cooling efficiency is deteriorated.
[0006]
Further, according to the camera mounting structure described in the publication, the rear camera 101 is moved by a rack and pinion mechanism. Of these, the rack 102 is exposed outside the vehicle when the camera is used. For this reason, dust or dirt may adhere to the teeth of the rack 102 during exposure. Then, the attached dust or dust may cause a problem in meshing between the teeth of the rack 102 and the teeth of the pinion 106. Therefore, the camera mounting structure described in the publication has low operational reliability.
[0007]
The camera mounting structure of the present invention has been completed in view of the above problems. Therefore, an object of the present invention is to provide a camera mounting structure with high designability and high operational reliability.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, a camera mounting structure according to the present invention includes a camera, a case in which the camera is housed and an opening in the front of the vehicle, a pivot provided at the upper end of the case and covering the opening so as to be freely opened and closed. A fixed emblem, a first arm portion pivoted on a drive device whose rear end is disposed rearward of the case, and a second arm portion pivoted on the front end of the first arm portion; And an arm that can push the camera and the emblem forward of the vehicle.When using the camera, the first arm portion is rotated by the driving force of the driving device, and the second arm portion is forward of the vehicle. moving the camera is projected disposed forward of the vehicle is pushed out from the case, the camera is to be able to image the camera to more forward as compared with the case of parallel fixed to emblem, env Characterized in that it is fixed with an inclination relative to the beam.

However, no gear member is disposed on the first arm portion and the second arm portion. Therefore, the first arm portion and the second arm portion are not easily affected by dust or dirt. For this reason, the camera mounting structure of the present invention has high operational reliability.
[0011]
Further, according to the camera mounting structure of the present invention, the driving device is arranged behind the case. Therefore, even when the emblem is arranged at the center of the front grille, the drive device is less likely to be exposed. For this reason, it is excellent in design property.
[0012]
The drive device according to the present invention includes a drive force transmission mechanism such as a gear in addition to a drive source such as a motor. That is, even when a driving source such as a motor is not disposed behind the case, when the driving force transmission mechanism is disposed behind the case, this driving force transmission device corresponds to the driving device according to the present invention. That is, the member that transmits the driving force to the camera and that is disposed behind the case is included in the driving device of the present invention.
[0013]

[0014]
That is, this structure fixes the front end of a 2nd arm part substantially perpendicularly with respect to an emblem. Further, when the camera is used, the first arm portion and the second arm portion are arranged substantially in series.
[0015]
According to the camera mounting structure described in the publication shown in FIG. 5, when the camera is used, the rear camera 101 is stopped in a state of protruding from the rear end of the vehicle. At this time, the rear camera 101 is supported by the rack 102 and the pinion 106. Therefore, a load due to the weight of the rear camera 101 and the emblem 100 is applied to the pinion 106 through the rack 102 while the camera is being used. Here, the load is applied to the outer peripheral edge of the pinion 106 where the teeth are formed. A drive shaft 107 is disposed at the inner peripheral side center of the pinion 106. For this reason, even if the load applied to the pinion 106 is small, a relatively large rotational load is applied to the drive shaft 107. The rotational load applied to the drive shaft 107 may adversely affect the drive device 108.
[0016]
On the other hand, according to the camera mounting structure of this configuration, the front end of the second arm portion 202 is fixed substantially perpendicular to the emblem 204, as schematically shown in FIG. In addition, when the camera is used, the drive shaft 200, the first arm portion 201, and the second arm portion 202 are arranged substantially in series as indicated by a one-dot chain line in the drawing. Therefore, the load due to the own weight of the camera 205 and the emblem 204 is applied to the drive shaft 200 from a substantially vertical direction. In other words, the load due to the weight of the camera 205 and the emblem 204 hardly affects the rotation direction of the drive shaft 200. For this reason, the rotational load applied to the driving device 203 is small. Therefore, according to the camera mounting structure of this configuration, there is little possibility of adversely affecting the drive device 203 when the camera is used.
