Telescopic cleaning device, detection system and method for assembling the telescopic cleaning device
A telescopic cleaning device for an optical sensor of a vehicle, including a support sheath, a sprayer body, a sprayer adapted to be movable in translation relative to the sprayer body, with the sprayer body being adapted to be inserted in translation into the sheath and adapted to be attached in the sheath by blocking means. The sprayer body is thus prevented from coming out of the sheath, allowing secure attachment of the sprayer body in a vehicle. The invention also relates to a detection system and a method for assembling the telescopic cleaning device.
1 . A telescopic cleaning device for an optical sensor of a vehicle, comprising
a support sheath,
a sprayer body,
a sprayer adapted to be movable in translation relative to the sprayer body, with
the sprayer body being adapted to be inserted in translation into the sheath and adapted to be attached in the sheath by a blocking means, the blocking means include tabs on the sprayer body or on the support sheath nesting elastically over and covering projections on the other of the sprayer body or of the support sheath and blocks translation of the sprayer body relative to the support sheath.
2 . The cleaning device as claimed in claim 1 , wherein the blocking means blocks rotation of the sprayer body relative to the sheath.
3 . The cleaning device as claimed in claim 2 , wherein the blocking means include guide surfaces on one or other of the sprayer body or of the support sheath interacting with at least one groove on the other of the sprayer body or of the support sheath.
4 . The cleaning device as claimed in claim 3 , wherein the at least one groove are frustoconical, the width of the at least one groove decreasing toward the bottom of the support sheath.
5 . A detection system comprising an optical sensor of a vehicle and a telescopic cleaning device configured to clean the optical sensor, with the telescopic cleaning device including:
a support sheath,
a sprayer body,
a sprayer adapted to be movable in translation relative to the sprayer body, with the sprayer body being adapted to be inserted in translation into the sheath and adapted to be attached in the sheath by a blocking means, the blocking means include tabs on the sprayer body or on the support sheath nesting elastically over and covering projections on the other of the sprayer body or of the support sheath and blocks translation of the sprayer body relative to the support sheath.
6 . A method for assembling a telescopic cleaning device, comprising:
inserting of a sprayer body into a sheath in a direction of translation of a sprayer toward the inside of the body,
attaching the sprayer body in the sheath with a blocking means, the blocking means include tabs on the sprayer body or on the sheath nesting elastically over and covering projections on the other of the sprayer body or of the sheath and blocks translation of the sprayer body relative to the sheath.
7 . The method as claimed in claim 6 , wherein the blocking means blocks rotation of the sprayer body relative to the sheath, the blocking means including guide surfaces on one or other of the sprayer body or of the sheath interacting with at least one groove on the other of the sprayer body or of the sheath.
