LASER SCANNING MODULE EMPLOYING A LASER SCANNING ASSEMBLY HAVING ELASTOMERIC WHEEL HINGES

摘要

A laser scanning module employs a scan mirror and magnet rotor subassembly supported by a stator structure using a pair of elastomeric wheel hinges. The scan mirror and magnet rotor subassembly includes: a scan mirror and magnet rotor subassembly having a rotor frame having a pair of rotor support posts aligned along a scan axis passing through the rotor frame; a scan mirror mounted on the rotor frame; and a permanent magnet mounted on the rotor frame. The elastomeric wheel hinge includes a central portion having an aperture for passage and fixed attachment of one rotor support post, a plurality of elastomeric spoke portions extending from the central portion and radially extending from the central aperture to a circumferential rim portion connected to the outer end portion of each spoke portion so as to form the elastomeric wheel hinge.

1. A laser scanning assembly for a module housing, comprising:
a scan mirror and magnet rotor subassembly comprising:
a rotor frame having a pair of rotor support posts aligned along a scan axis passing through the rotor frame;a scan mirror mounted on the rotor frame; anda magnet mounted on the rotor frame; a pair of elastomeric wheel hinges torsionally supporting the scan mirror and magnet rotor subassembly such that the scan mirror and magnet rotor subassembly oscillate freely about the scan axis, wherein each elastomeric wheel hinge comprises: (i) a central portion having an aperture for passage and fixed attachment of one of the rotor support posts; (ii) a plurality of elastomeric spoke portions extending from the central portion and radially extending from the aperture; and (iii) a circumferential rim portion connected to an outer end portion of each spoke portion; and a stator structure mounted stationary relative to the module housing, comprising a pair of support members for supporting each of the elastomeric wheel hinges.
