Description:
CROSS REFERENCE TO RELATED APPLICATION 
     The present application claims priority to and the benefit of Korean Patent Application No. 10-2021-0162110, filed Nov. 23, 2021, the entire contents of which are incorporated herein by reference. 
     BACKGROUND 
     Field 
     The present disclosure relates to a device for mounting interior parts of a vehicle and, more particularly, to a device for mounting interior parts of a vehicle, which allows interior parts such as sun visors to be detachably installed on a vehicle body panel. 
     Description of the Related Art 
     The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. 
     A sun visor of a vehicle shields a driver&#39;s eyes from sunlight shining through the vehicle (e.g., a front windshield). The sub visor is typically rotatably mounted on the headliner of driver and front passenger seats. 
     In general, a pivot arm is connected to one side of the sun visor and this pivot arm is rotatably connected to a pivot arm body mounted on the vehicle body panel. 
     Accordingly, a user can use the sun visor while rotating the sun visor around the pivot arm in a desired direction. 
     As a conventional method for assembling such a sun visor, fastening the pivot arm body connected to the pivot arm to the vehicle body panel using screws or the like is mainly used. However, there is a problem in that assembly labor is required. For example, the pivot arm body is fastened to the vehicle body panel by one-point or two-point mounting of the screws by an operator using a dedicated tool, and the assembly quality may be deteriorated due to incomplete fastening during assembly. 
     In addition, as another conventional method for assembling the sun visor, inserting and fastening a clip mounted on the pivot arm body to the vehicle body panel is used. However, this method also has a problem that a separate dismantling operation is required to forcibly remove the clip using a dedicated tool for replacement or maintenance of the sun visor because once the clip is fastened to the vehicle body panel, it cannot be removed, and that the pivot arm body is damaged due to forced removal.

     The base plate  10  is a part to which a pivot arm of a sun visor is rotatably fastened. The base plate  10  is closely attached to a headliner which is a part forming an interior ceiling surface of the vehicle. The base plate  10  is provided in a structure that is fastened to a vehicle body panel inside the headliner using a clip. 
     To this end, the base plate  10  is provided in a structure in which the first wall  11  and the second wall  12  dividing a sliding path  13  with a lower opening are integrally formed facing each other in the front-rear direction on the upper surface of one side of the base plate, and a pivot arm assembly hole  14  is formed on the upper surface of the other side of the base plate. 
     Between the first wall  11  and the second wall  12 , a clip  20  is positioned. The clip  20  is detachably fastened to assembly holes of the vehicle body panel while supporting the bottom of the base plate  10 . 
     The clip  20  supports the bottom of the base plate  10 , and includes elastic fastening plates  24  having locking jaws  25  to be fastened to the assembly holes of the vehicle body panel. 
     In one embodiment, the clip  20  includes: a front plate  21 , a back plate  22 , and a top plate  23  that is integrally connecting the upper ends of the front plate  21  and the back plate  22  for form a basic frame. The elastic fastening plate  24  is integrally formed on each of the front plate  21  and the back plate  22  so as to be able to spread outward. In another embodiment, base plate support ends  27  are integrally formed at lower ends of the front plate  21  and the back plate  22  to support the bottom of the base plate  10 . The base plate support ends  27  are bent in the front-rear direction to support the bottom of the base plate  10 . 
     In one embodiment, the locking jaw  25  of the elastic fastening plate  24  is formed in a bent structure to protrude outward so that it can be inserted into the assembly hole of the vehicle body panel and locked. 
     In one embodiment, position-regulating protrusions  26  are formed at both lower ends of the elastic fastening plate  24  of the clip  20 . The position-regulating protrusions  26  are closely supported on the inner surfaces of the first wall  11  and the second wall  12  and protrude further in the front-rear direction when the elastic fastening plates  24  are spread outward. 
     Here, the position-regulating protrusions  26  are being closely supported on the inner surfaces of the first wall  11  and the second wall  12  when the elastic fastening plates  24  are spread outward, thereby constantly regulating a distance that the elastic fastening plate  24  spreads outwardly while limiting the vibration or shaking of the elastic fastening plate  24  in the vertical, left, and right directions by external force. 
     As illustrated in  FIG.  2   , The base plate support ends  27  of the clip  20  are inserted and seated in support grooves  16  formed on the bottom surface of the base plate  10  to support the base plate  10  after passing through the lower opening  15  of the sliding path  13  of the base plate  10 .

     Here, when the clip fastening/removal bar  30  moves forward, the pressurizing protrusions  31  protruding from both sides of the clip fastening/removal bar  30  push the elastic fastening plates  24  of the clip  20  outward, and the locking jaws  25  of the elastic fastening plates  24  can be lock-fastened to the assembly holes of the vehicle body panel. 
     In one embodiment, a lever  40  having a hinge shaft  41  is rotatably fastened to the base plate  10 . 
     In particular, a hinge hole  18  is formed between the sliding path  13  of the base plate  10  and the pivot arm assembly hole  14  so that the hinge shaft  41  is fastened along the front-rear direction. 
     In another embodiment, a push body  42  is formed on the hinge shaft  41  of the lever  40  to push the clip fastening/removal bar  30  in the direction of removal (backward direction). 
     In other embodiment, the push body  42  includes a vertical plate  43  integrally formed on the hinge shaft  41  of the lever  40 , and a pressurizing plate  44  integrally extended from the rear end of the vertical plate  43  to push the clip fastening/removal bar  30  in the direction of removal (backward direction) when the lever  40  rotates downward. 
     In another embodiment, the push body  42  may be formed of a gear structure and other similar structures capable of pushing the clip fastening/removal bar  30  in the direction of removal while rotating together with the rotation of the hinge shaft  41  according to the downward rotation of the lever  40 . 
     Here, a hook  45  is formed to protrude from the upper surface of the front end of the lever  40 , and a fastening jaw  19  to which the hook  45  is fastened is formed at one end of the base plate  10 . Accordingly, when the hook  45  is fastened to the fastening jaw  19 , the lever  40  may be firmly fixed to the bottom of the base plate  10 . 
     Meanwhile, a cover  50  for invisibly covering the clip  20  and the hinge shaft  41  is fastened to the bottom of the base plate  10 . 
     To this end, a plurality of fastening bars  52  having locking holes  51  are formed to protrude from the upper surface of the cover  50 , and insertion holes  53  are formed in the base plate  10 . The fastening bars  52  are inserted into the insertion holes  53 , and locking protrusions  54  are formed on the outer surfaces of the first wall  11  and the second wall  12  formed on the base plate  10  to be lock-inserted into the locking holes  51  of the fastening bars  52 . 
     When the fastening bars  52  of the cover  50  are inserted upward through the insertion holes  53  of the base plate  10 , the locking protrusions  54  are lock-inserted into the insertion holes  53  of the inserted fastening bars  52 , then the cover  50  is fixed to the bottom of the base plate  10  while covering the bottom of the base plate  10 . 
     Here, the assembling and dismounting operation of the device for mounting interior parts of a vehicle according to the first embodiment of the present disclosure having the above configuration is described as follows. 
       FIG.  4    is a longitudinal cross-sectional view showing a state in which a clip of the device for mounting interior parts of a vehicle is fastened to a vehicle body panel according to an embodiment of the present disclosure. 
     The base plate  10  is a component rotatably fastened to the pivot arm of the sun visor. Because the clip  20  is fastened to the assembly holes  62  formed in the vehicle body panel  60  inside a headliner  70 , the base plate  10  may be firmly fixed to the headliner  70 , which is a component constituting the interior ceiling surface of the vehicle. 
     To this end, the base plate  10  is brought into close contact with the headliner  70  first. 
     Then, when the operator inserts a finger or a pin tool into the manipulation hole  32  of the clip fastening/removal bar  30  through the lower opening  15  of the base plate  10  and pulls the clip fastening/removal bar  30  in the forward direction (direction of insertion), the clip fastening/removal bar  30  moves forward along the inner space of the sliding path  13  and the clip  20 . 
     When the clip fastening/removal bar  30  moves forward, the pressurizing protrusions  31  protruding from both sides of the clip fastening/removal bar  30  push the elastic fastening plates  24  of the clip  20  outward, and the locking jaws  25  of the elastic fastening plates  24  may be lock-fastened to the upper outer peripheral surfaces of the assembly holes  62  of the vehicle body panel  60  as shown in  FIG.  4   . 
     Here, the position-regulating protrusions  26  of the clip  20  are being closely supported on the inner surfaces of the first wall  11  and the second wall  12 , thereby constantly regulating a distance that the elastic fastening plate  24  spreads outwardly while limiting the vibration or shaking of the elastic fastening plate  24  in the vertical, left, and right directions by external force. 
     As such, by the base plate  10  being brought into close contact with the headliner  70 , and by spreading of the elastic fastening plate  24  of the clip  20  according to the forward movement operation of the clip fastening/removal bar  30 , the device for mounting interior parts of a vehicle may be easily assembled to the vehicle body panel  60 . 
     As discussed above, the pivot arm (not shown) of the sun visor is pivotally fastened to the pivot arm assembly hole  14  formed on the other side of the base plate  10 . 
     Also, when the base plate  10  is assembled to the vehicle body panel  60 , the lever  40  may rotate in the closing direction so that the hook  45  is fastened to the fastening jaw  19 , and the lever  40  comes in close contact with and fixed to the bottom of the base plate  10 . 
     In addition, when the base plate  10  is firmly fixed to the headliner  70  due to the lock-fastening of the clip  20  to the vehicle body panel  60 , by inserting the fastening bars  52  of the cover  50  upward through the insertion holes  53  of the base plate  10  and by lock-inserting the locking protrusions  54  into the locking holes  51  of the inserted fastening bars  52 , the cover  50  may be fixed to the bottom of the base plate  10  while covering the bottom of the base plate  10 . 
       FIG.  5    is a cross-sectional view showing a state in which a clip of the device for mounting interior parts of a vehicle is fastened to a vehicle body panel according to an embodiment of the present disclosure, and  FIG.  6    is a cross-sectional view showing a state in which a clip fastening/removal bar is pushed in the direction of removal by a lever operation of the device for mounting interior parts of a vehicle according to an embodiment of the present disclosure. 
     Referring to  FIGS.  5  and  6   , for maintenance and replacement of parts such as a sun visor and a pivot arm, by the reverse rotation (downward rotation) of the lever  40  and the backward removal operation of the clip fastening/removal bar  30 , the clip  20  may be automatically removed from the vehicle body panel  60  without the use of a separate dedicated tool. 
     To this end, after removing the cover  50 , when the lever  40  is rotated in the downward direction the push body  42  formed on the hinge shaft  41  of the lever  40  pushes the clip fastening/removal bar  30  in the direction of removal (backward direction). 
     In other words, as the pressurizing plate  44  of the push body  42  integrally formed with the hinge shaft  41  of the lever  40  rotates, the clip fastening/removal bar  30  is pushed in the direction of removal (backward direction) as shown in  FIG.  6   . 
     As the clip fastening/removal bar  30  moves in the direction of removal, the pressurizing protrusions  31  protruding from both sides of the clip fastening/removal bar  30  are separated from the elastic fastening plates  24  of the clip  20 , the pressing force of the pressurizing protrusions  31  is released, and thus the locking jaws  25  of the elastic fastening plates  24  are separated from the assembly holes  62  of the vehicle body panel  60  due to the elastic restoring force of the elastic fastening plates  24 . 
     Accordingly, the clip  20  may be easily removed downwardly from the vehicle body panel  60  and the base plate  10  may also be easily removed according to the removal of the clip  20 , and thus maintenance and replacement of parts such as a sun visor and a pivot arm may be performed easily.

     Here, as the base plate support ends  27  of the clip  20  are inserted and seated in the support grooves  16  of the base plate  10 , it is possible to prevent contact interference with the cover  50  fastened to the lower surface of the base plate  10  and thus the cover  50  may be easily and firmly fastened to the bottom surface of the base plate  10 . 
     Meanwhile, a lever  40  is rotatably fastened to the base plate  10 . 
     To this end, hinge bars  46  rotatably fastened to the base plate  10  are formed to protrude from the upper surface of the other side of the lever  40 , and guide grooves  47  are formed between the sliding path  13  of the base plate  10  and the pivot arm assembly hole  14  so that the hinge bars  46  are rotatably and movably inserted and fastened to the front and rear surfaces thereof. 
     In one embodiment, the guide grooves  47  are formed to be inclined downward toward one side of the base plate  10 . 
     Therefore, when the lever  40  is rotated in the downward direction, the hinge bars  46  move downward along the guide grooves  47  of the base plate  10 , and the downward rotation of the lever  40  may be achieved. 
     In particular, a clip fastening/removal bar  30  is integrally formed on the upper surface of the lever  40 . The clip fastening/removal bar  30  is detachably inserted into the inner space of the sliding path  13  and the clip  20 , and has, on the front and rear surfaces thereof, pressurizing protrusions  31  pressurizing the elastic fastening plates  24  of the clip  20  outwardly. 
     Meanwhile, elastic hooks  48  are formed to protrude from the upper surface of the front end of the lever  40 , and fastening jaws  19  to which the hooks  45  are fastened are formed at one end of the base plate  10 , and accordingly, when the hooks  45  are fastened to the fastening jaws  19 , the lever  40  may be firmly fixed to the bottom of the base plate  10 . 
     Here, the assembling and dismounting operation of the device for mounting interior parts of a vehicle according to the second embodiment of the present disclosure having the above configuration is described as follows. 
       FIG.  10    is a longitudinal cross-sectional view showing a state in which a clip of the device for mounting interior parts of a vehicle is fastened to a vehicle body panel according to another embodiment of the present disclosure. 
     The base plate  10  is a component rotatably fastened to the pivot arm of the sun visor, and by fastening the clip  20  to the assembly holes  62  formed in the vehicle body panel  60  inside a headliner  70 , the base plate  10  may be firmly fixed to the headliner  70 , which is a component constituting the interior ceiling surface of the vehicle. 
     To this end, the base plate  10  is brought into close contact with the headliner  70  first. 
     Then, an operator rotates the lever  40  upward from the open position to close it. 
     Here, when the lever  40  is rotated upward, the hinge bars  46  move upward along the guide grooves  47  of the base plate  10  so that the lever  40  may be rotated upward. 
     In particular, when the lever  40  is rotated upward, the clip fastening/removal bar  30  integrally formed on the upper surface of the lever  40  enters the inner space of the sliding path  13  and the clip  20  of the base plate  10 , and the pressurizing protrusions  31  push the elastic fastening plates  24  of the clip  20  outward, and thus the locking jaws  25  of the elastic fastening plates  24  may be lock-fastened to the upper outer peripheral surfaces of the assembly holes  62  as shown in  FIG.  10   . 
     Here, the position-regulating protrusions  26  of the clip  20  are being closely supported on the inner surfaces of the first wall  11  and the second wall  12 , thereby constantly regulating the distance the elastic fastening plate  24  spreads outwardly while limiting the vibration or shaking of the elastic fastening plate  24  in the vertical, left, and right directions by external force. 
     As such, when the lever  40  rotates upward, the pressurizing protrusions  31  of the clip fastening/removal bar  30  formed on the lever  40  push the elastic fastening plates  24  of the clip  20  outward, and the locking jaws of the elastic fastening plates  24  are easily lock-fastened to the upper outer peripheral surfaces of the assembly holes  62  of the vehicle body panel  60 , and thus the base plate  10  may be closely fixed to the headliner  70 . 
     As discussed above, a pivot arm (not shown) of a sun visor is pivotally fastened to the pivot arm assembly hole  14  formed on the other side of the base plate  10 . 
     Here, when the lever  40  is completely rotated in the closing direction, the hooks  45  are fastened to the fastening jaws  19 , and the lever  40  may be firmly fixed to the bottom of the base plate  10 . 
       FIG.  11    is a cross-sectional view showing a state in which a clip of the device for mounting interior parts of a vehicle is fastened to a vehicle body panel according to another embodiment of the present disclosure, and  FIG.  12    is a cross-sectional view showing a state in which a clip fastening/removal bar is pushed in the direction of removal by a lever operation of the device for mounting interior parts of a vehicle according to another embodiment of the present disclosure. 
     Referring to  FIGS.  11  and  12   , for maintenance and replacement of parts such as a sun visor and a pivot arm, by the reverse rotation (downward rotation) of the lever  40  and the removal operation of the clip fastening/removal bar  30 , the clip  20  may be automatically removed from the vehicle body panel  60  without the use of a separate dedicated tool. 
     To this end, when the lever  40  is rotated in the downward direction, the hinge bars  46  move downward along the guide grooves  47  of the base plate  10  and the clip fastening/removal bar  30  integrally formed on the upper surface of the lever  40  comes out of the inner space of the sliding path  13  and the clip  20  of the base plate  10  as shown in  FIG.  12   . 
     Also, as the pressurizing protrusions  31  of the clip fastening/removal bar  30  are separated from the elastic fastening plates  24  of the clip  20 , the pressing force of the pressurizing protrusions  31  is released, and thus the locking jaws  25  of the elastic fastening plates  24  are separated from the assembly holes  62  of the vehicle body panel  60  due to the elastic restoring force of the elastic fastening plates  24 . 
     Accordingly, the clip  20  may be easily removed downwardly from the vehicle body panel  60  and the base plate  10  may also be easily removed according to the removal of the clip  20 , and thus maintenance and replacement of parts such as a sun visor and a pivot arm may be performed easily. 
     As described above, the device for mounting interior parts of a vehicle of the present disclosure has been described for the purpose of mounting the sun visor pivot arm, however, it should be noted that the device can be used for the purpose of mounting other interior parts (handle, hanger, etc.) other than the sun visor pivot arm. 
     Although the present disclosure has been described in detail for each embodiment above, the scope of the present disclosure is not limited to each embodiment described above, and various modifications and improvements by those having ordinary skill in the art using the basic concept of the present disclosure are also included in the scope of the present disclosure.
