Protective capsules for earth moving machines

A device for an earth moving machine comprising:

• a cavity;
• and
• a capsule comprising one or more walls arranged so as to form both an inner chamber configured for housing an electronic device, and an opening through which the inner chamber is accessed, the opening being at least partially covered by a cover, wherein the one or more walls provide the capsule in at least one portion thereof with a geometry that is convex and adapted for allowing extraction of the capsule from the cavity by rotating the capsule about a rotation axis;
• wherein a cross-section of the capsule where the at least one portion starts extends over a plane, the plane being defined by both a longitudinal axis of the capsule and an axis transverse thereto;
• wherein the rotation axis is parallel to the axis transverse to the longitudinal axis;
• wherein the capsule is introducible in the cavity;
• wherein the geometry of the at least one portion of the capsule fits in at least one portion of the cavity, and the geometry of the at least one portion of the cavity is adapted for allowing extraction of the capsule from the cavity by rotating the capsule about the rotation axis.

An assembly comprising:

• a first device for an earth moving machine, and a second device for the earth moving machine;
• wherein the first device comprises:
• a cavity, and a capsule comprising one or more walls arranged so as to form both an inner chamber configured for housing an electronic device, and an opening through which the inner chamber is accessed, the opening being at least partially covered by a cover, wherein the one or more walls provide the capsule in at least one portion thereof with a geometry that is convex and adapted for allowing extraction of the capsule from the cavity by rotating the capsule about a rotation axis;
• wherein a cross-section of the capsule where the at least one portion starts extends over a plane, the plane being defined by both a longitudinal axis of the capsule and an axis transverse thereto;
• wherein the rotation axis is parallel to the axis transverse to the longitudinal axis;
• wherein the capsule is introducible in the cavity;
• wherein the geometry of the at least one portion of the capsule fits in at least one portion of the cavity, and the geometry of the at least one portion of the cavity is adapted for allowing extraction of the capsule from the cavity by rotating the capsule about the rotation axis;
• wherein the second device is attached or attachable to the first device;
• wherein the capsule of the first device comprises at least one Hall-effect sensor, each Hall-effect sensor of the at least one Hall-effect sensor being arranged on one groove of one or more grooves of the cover, and the second device comprising one or more magnets arranged such that each magnet is at a distance from one Hall-effect sensor when the second device is attached to the first device, the distance being less than 5 cm.

A method comprising:

• manufacturing a capsule for protecting an electronic device for an earth moving machine, the capsule comprising one or more walls arranged so as to form both an inner chamber configured for housing said electronic device, and an opening through which the inner chamber is accessible;
• forming a cover;
• coupling the cover with the one or more walls so as to at least partially cover the opening;
• forming the one or more walls such that the capsule comprises, in at least one portion thereof, a geometry that is convex and adapted for allowing extraction of the capsule from a cavity of the earth moving machine by rotating the capsule about a rotation axis, wherein a cross-section of the capsule where the at least one portion starts extends over a plane, the plane being defined by both a longitudinal axis of the capsule and an axis transverse thereto, wherein the rotation axis is parallel to the axis transverse to the longitudinal axis.
