a substrate accommodated and disposed in the housing; a rotary hinge rod rotatably disposed within the housing and contactingly connected to a lever cooperating unit operated in cooperation with a vehicle gearshift lever so that the rotary hinge rod is rotated cooperatively with the vehicle gearshift lever when the vehicle gearshift lever is rotated; a sensing unit comprising a magnetic sensor disposed on the substrate and a magnet disposed at the rotary hinge rod to correspond to the magnetic sensor; and a rotary hinge rod torsion unit disposed within the housing in a manner to be supportingly contacted at one end thereof with the rotary hinge rod and at the other end thereof with the inside of the housing to elastically support the rotary hinge rod when the rotary hinge rod is rotated. ## Claims ### Claim 1 A shifting range rotary sensing device for a vehicle, comprising: a housing (100, 800); a substrate (400) accommodated and disposed in the housing (100, 800); a rotary hinge rod (500) rotatably disposed within the housing (100, 800) and contactingly connected to a lever cooperating unit (20) operated in cooperation with a vehicle gearshift lever (30) so that the rotary hinge rod (500) is rotated cooperatively with the vehicle gearshift lever (30) when the vehicle gearshift lever (30) is rotated; a sensing unit (430, 600) comprising a magnetic sensor (430) disposed on the substrate (400) and a magnet (600) disposed at the rotary hinge rod (500) to correspond to the magnetic sensor (430); and a rotary hinge rod torsion unit (700) disposed within the housing (100, 800) in such a manner as to be supportingly contacted at one end thereof with the rotary hinge rod (500) and at the other end thereof with the inside of the housing (100, 800) so as to elastically support the rotary hinge rod (500) when the rotary hinge rod (500) is rotated. ### Claim 2 (depends on 1) The shifting range rotary sensing device according to claim 1, wherein the housing (100, 800) comprises: a housing body (100) disposed in the vehicle; and a housing cover (800) engagingly coupled to the housing body (100), wherein the housing cover (800) has a cover opening part (801) formed thereon, and wherein the rotary hinge rod (500) is exposed to the outside through the cover opening part (801) so as to be connected to the lever cooperating unit (20). ### Claim 3 (depends on 2) The shifting range rotary sensing device according to claim 2, wherein the lever cooperating unit (20) comprises a cooperating rib (21) extending downwardly from one side thereof, and wherein the rotary hinge rod (500) comprises: a hinge rod mounting part (530) rotatably engaged to a housing cover rod mounting part (820) formed at the housing cover (800); a hinge rod body (501) connected to the hinge rod mounting part (530); and a hinge rod extension part (503) extending downwardly from the hinge rod body (501) and including a hinge rod rib insertion part (510) defined therebetween to accommodate the cooperating rib (21) therein. ### Claim 4 (depends on 3) The shifting range rotary sensing device according to claim 3, wherein the hinge rod body (501) comprises a rod body magnet accommodating part (502) formed therein to allow the magnet (600) to be accommodated therein. ### Claim 5 (depends on 4) The shifting range rotary sensing device according to claim 4, wherein the sensing unit detects a preset shifting range including one or more of P(parking), D(driving), R(rearward moving), and N(neutral shifting) of the vehicle, and wherein a buffer range is provided between at least two adjacent shifting ranges of the preset shifting range. ### Claim 6 (depends on 5) The shifting range rotary sensing device according to claim 5, wherein the rotary hinge rod torsion unit (700) is implemented as a torsion spring. ### Claim 7 (depends on 6) The shifting range rotary sensing device according to claim 6 wherein the rotary hinge rod torsion unit (700) comprises: a torsion coil part (710) configured to allow the hinge rod mounting part (530) to penetrate therethrough; a torsion coil rod support part (720) supported by a hinge rod torsion support part (520) extending from the hinge rod body (501) at its one end connected to the torsion coil part (710); and a torsion coil cover support part (730) supported by a cover torsion support part (810) extending from the housing cover (800) at its the other end connected to the torsion coil part (710). ### Claim 8 (depends on 7) The shifting range rotary sensing device according to claim 7, wherein the hinge rod torsion support part (520) comprises a hinge rod torsion support groove (521) formed thereon to allow the torsion coil rod support part (720) to be insertingly disposed therein; and wherein the cover torsion support part (810) comprises a cover torsion support groove (811) formed thereon to allow the torsion coil cover support part (730) to be insertingly disposed therein. ### Claim 9 (depends on 7) The shifting range rotary sensing device according to claim 7, wherein the substrate (400) comprises a through-hole (401) formed therein, and wherein the housing body (100) comprises a support rib (110) extending protruding from one side of the hinge rod body (501) to an opposing side of the hinge rod mounting part (530) while penetrating through the through-hole (401) to maintain a gap between the hinge rod body (501) and the substrate (400). ### Claim 10 (depends on 1) The shifting range rotary sensing device according to claim 1, further comprising a driving mode switch (900) disposed on the substrate (400) and configured to allow a user to select a driving mode of the vehicle through its manipulation by the user.
