Locking unit for vehicle

Abstract

A locking unit of a vehicle may include a mounting portion having a plurality of mounting grooves formed on an upper surface thereof, wherein supporting legs of a vehicle interior portion are configured to be inserted into the mounting grooves, installing the vehicle interior portion in the indoor compartment of the vehicle; and a plurality of locking devices provided on inner peripheries of the mounting grooves inside the mounting portion, respectively, such that, by selectively fixing or unfixing the supporting legs of the vehicle interior portion inserted in the mounting grooves, the vehicle interior portion is attached to or detached from the mounting portion.

What is claimed is: 
     
         1 . A locking unit for a vehicle, the locking unit comprising:
 a mounting portion having a plurality of mounting grooves formed on an upper surface thereof, wherein supporting legs of a vehicle interior portion are insertable into the plurality of mounting grooves; and   a plurality of locking devices provided on inner peripheries of the plurality of mounting grooves inside the mounting portion, respectively,   wherein by selectively fixing the supporting legs of the vehicle interior portion in the plurality of mounting grooves, the vehicle interior portion is selectively attached to the mounting portion.   
     
     
         2 . The locking unit of  claim 1 , wherein the vehicle interior portion includes a seat or a table, and one or more supporting legs are provided on a lower end portion of the seat or the table. 
     
     
         3 . The locking unit of  claim 1 , wherein the mounting portion includes one or more panels, and the one or more panels are coupled to an upper surface of a vehicle floor to form a portion of a floor. 
     
     
         4 . The locking unit of  claim 1 ,
 wherein a locking groove is formed on an external circumferential surface of each of the supporting legs of the vehicle interior portion,   wherein a locking protrusion is provided on a side of each of the locking devices, and   wherein each of the locking devices selectively inserts the locking protrusion into the locking groove so that the supporting legs of the vehicle interior portion are selectively coupled to the plurality of mounting grooves.   
     
     
         5 . The locking unit of  claim 4 , further including an actuator connected to the locking protrusion and provided at a side of each of the locking devices,
 wherein each of the locking devices selectively inserts the locking protrusion into the locking groove when the actuator selectively moves the locking protrusion toward the locking groove.   
     
     
         6 . The locking unit of  claim 4 ,
 wherein each of the locking devices inserts the locking protrusion into the locking groove through elastic force when the supporting legs are inserted in the plurality of mounting grooves, and   wherein each of the supporting legs has a release portion provided at a side of the locking groove, and the release portion is configured to push the inserted locking protrusion to the outside thereof and thus unfixes the supporting legs of the vehicle interior portion from the plurality of mounting grooves, when the release portion is pressed.   
     
     
         7 . The locking unit of  claim 6 , wherein a first portion of the locking protrusion is hingedly fixed so that the locking protrusion rotates around the first portion of the locking protrusion by the elastic force. 
     
     
         8 . The locking unit of  claim 6 , wherein each of the supporting legs has a channel through which the release portion is slidable so that the release portion is configured to selectively push a second portion of the locking protrusion so as to release the second portion of the locking protrusion from the locking groove. 
     
     
         9 . The locking unit of  claim 8 , further including a release member mounted in the channel,
 wherein when an end portion of the release portion presses the release member, the release member moves in a radial direction of the channel to push the second portion of the locking protrusion so as to release the locking protrusion from the locking groove.   
     
     
         10 . The locking unit of  claim 4 ,
 wherein a magnetic force portion connected to the locking protrusion is provided at a side of each of the locking devices, and   wherein each of the locking devices selectively attaches the locking protrusion to the locking groove through magnetic force of the magnetic force portion so as to selectively insert the locking protrusion into the locking groove.   
     
     
         11 . The locking unit of  claim 10 , wherein the magnetic force portion includes a fixation magnet, a rotating magnet, and an electromagnet, the magnetic force portion has a magnetic path changed according to a magnetism change of the electromagnet, the supporting legs are fixed to the plurality of mounting grooves when the magnetic force portion and each of the supporting legs together form the magnetic path, and the supporting legs are unfixed from the plurality of mounting grooves when only the magnetic force portion forms the magnetic path. 
     
     
         12 . The locking unit of  claim 1 , further including a cover portion provided at an upper end portion of each of the plurality of mounting grooves for covering each of the plurality of mounting grooves,
 wherein the cover portion is removable when the vehicle interior portion is provided in an indoor compartment of the vehicle.
