Electronics module for mirrors
View Patent ↗An electronics module is attachable to an exterior mirror of a vehicle and supports a camera and/or a display. The electronics module may be an add-on device that is retrofittable to the exterior mirror. The display may be arranged to display an indication of a distance between a back of the vehicle and an object.
1. An add-on electronics module for attachment to an exterior mirror housing of a vehicle, the exterior mirror housing having an exterior housing surface having a convex end at a bottom of the exterior mirror housing and having a forward facing surface in a direction of vehicle travel and having a top of the exterior mirror housing, the add-on electronics module comprising:
a module housing, wherein the module housing has a shape conforming to a shape of a bottom end of the exterior mirror housing so as to facilitate fitting of the add-on electronics module to the bottom of the exterior mirror housing, the module housing being shaped to receive at least a portion of the convex bottom end of the exterior housing surface of the external mirror housing in the module housing when the module housing is mounted on the external mirror housing, the module housing being shaped to be free of the top of the exterior mirror housing and to be free of portions of the forward facing surface of the exterior mirror housing, the module housing being shaped to match the bottom of the exterior mirror housing the module housing providing a rearwardly facing portion when mounted on the exterior mirror housing;
fastening devices permitting the module housing to be fastened to the exterior mirror housing, wherein the fastening devices are arranged to facilitate fitting of the add-on electronics module to the exterior mirror housing; and
electronics contained within and supported in the module housing.
2. The add-on electronics module of claim 1 , further including a camera supported by the module housing, the camera being enclosed within the module housing when the module housing is mounted on the external mirror housing, the enclosure being formed by cooperative engagement of the external mirror housing and the module housing, the camera being directed through the rearwardly facing portion of the module housing.
3. The add-on electronics module as claimed in claim 2 , wherein the electronics includes a printed circuit board populated by electrical components to form an operational electrical circuit that is operable to process image data from the camera.
4. The add-on electronics module of claim 1 , further including a camera and a display on the rearwardly facing portion of the module housing.
5. The add-on electronics module of claim 1 , wherein the fastening devices comprises holes through the module housing.
6. The add-on electronics module as claimed in claim 1 , wherein the module housing is configured to fit onto a surface of the external mirror housing so that the bottom of the exterior mirror housing fits into the module housing.
7. The add-on electronics module as claimed in claim 6 , wherein the module housing is cup-shaped and configured so that a portion of the external mirror housing fits into the cup-shaped module housing.
8. The add-on electronics module as claimed in claim 1 , wherein the module housing is configured to be mountable to the external mirror housing without the module housing fitting into an opening or recess in the external mirror housing when mounted on the external mirror housing.
9. The add-on electronics module as claimed in claim 1 , wherein the electronics includes a printed circuit board populated by electrical components to form an operational electrical circuit.
10. An add-on electronics module for attachment to an exterior mirror housing of a vehicle, the exterior mirror housing having an exterior housing surface having a convex end at a bottom of the exterior mirror housing and having a forward facing surface in a direction of vehicle travel and having a convex end at a top of the exterior mirror housing, the add-on electronics module comprising:
a module housing, wherein the module housing has a shape conforming to a shape of the exterior mirror housing so as to facilitate fitting of the add-on electronics module to the exterior mirror housing, the module housing being shaped to receive at least a portion of the convex bottom end of the exterior housing surface of the external mirror housing in the module housing when the module housing is mounted on the external mirror housing, the module housing being shaped to be free of portions of the forward facing surface of the exterior mirror housing, the module housing being shaped to match the exterior mirror housing the module housing providing a rearwardly facing portion when mounted on the exterior mirror housing;
fastening devices permitting the module housing to be fastened to the exterior mirror housing, wherein the fastening devices are arranged to facilitate fitting of the add-on electronics module to the exterior mirror housing; and
electronics contained within and supported in the module housing.
