       FIGS.  1  to  3    are views showing various embodiments of a vehicle body to which embodiments of the present invention are applied. 
     A conventional vehicle has been manufactured such that a vehicle body is molded into a monocoque body made in an integrated frame, a suspension and a wheel are mounted on a lower portion, and a driving device is mounted in the front or rear. A vehicle made of a monocoque body may be designed to apply to an internal combustion engine vehicle in general, and such a vehicle body manufacturing method needs molds in different shapes for respective vehicle types, thereby increasing manufacturing cost, incurring additional costs in the development of new vehicle types, and complicating the manufacturing process during manufacturing. 
     However, the development of an electric vehicle has led to the development of an integrated driving system in which a battery, a suspension, a wheel, a motor, and the like are all included by a skateboard-type platform method. In such a skateboard-type platform vehicle, a vehicle may be coupled to the top of the skateboard platform and, accordingly, vehicle bodies may be formed in different shapes even on the same skateboard platform. 
     As shown in  FIG.  1   , a vehicle body may be manufactured such that a space in which a driver drives and a cargo space in which cargo is loaded are separated, depending on the use of the vehicle. Or, a vehicle body may be manufactured into a loading space for cargo loading without a driver space in a fully autonomous driving vehicle. 
     Further, as shown in  FIG.  2   , a vehicle body may be manufactured in various shapes for the appearance of the vehicle. 
     For this purpose, as shown in  FIG.  3   , the vehicle to which embodiments of the present invention are applied is designed such that a lower body  500  and a side sill  100  of the vehicle are coupled to the top of the skateboard platform and pillar members  300  are coupled thereto. 
     Embodiments of the present invention are designed to facilitate the coupling of the pillar member  300  to the side sill  100 , and this allows the reduction of manufacturing cost by applying the pillar members to various vehicle types without limit to the positions and number of pillar members and the simplification of the manufacturing process by eliminating the need for a separate mold for every vehicle type. 
       FIG.  4    is a perspective view showing the side sill  100 , a coupling member  200 , and the pillar member  300  of the vehicle coupled to each other according to an embodiment of the present invention;  FIG.  5    is an enlarged perspective view showing the coupling member  200  of a vehicle according to an embodiment of the present invention;  FIG.  6    is a cross-sectional view of a coupling member taken along the line A-A in  FIG.  5   ;  FIG.  7    is a view showing a side sill, a coupling member, and a pillar member coupled to each other viewed from the outside of a vehicle in  FIG.  1   ; and  FIG.  8    is a perspective view showing a cover  260  coupled to a coupling member  200  of a vehicle body according to an embodiment of the present invention. 
     A preferable embodiment of the present invention will be described with reference to  FIGS.  4  to  8   . 
     The side sills  100  are coupled to a floor on either side of a conventional vehicle to protect the vehicle against a side collision, and a pillar member  300  to be connected to a vehicle roof may be connected to the top of the side sill  100 . 
     The side sill  100  and the pillar member  300  were integrally formed in the structure of the conventional vehicle, and such a configuration had the problem of increasing the manufacturing cost of a vehicle. 
     Embodiments of the present invention can resolve such a problem of a vehicle body. 
     A vehicle body according to embodiments of the present invention includes a side sill  100  coupled to a side of a vehicle floor and configured to extend in the front-rear direction, a coupling member  200  coupled to the top of the side sill  100  and provided with a coupling groove  240  penetrating in the up-down direction, and a pillar member  300  extending in the up-down direction such that an upper end portion is connected to the roof and a lower end portion is inserted into the coupling groove  240  to be coupled to the coupling member  200 . 
     A pair of side sills  100  extending in the front-rear direction to be coupled to either side of the vehicle floor may be provided and the coupling member  200  may be coupled to the top of the respective side sill  100 . 
     A coupling groove  240  penetrating in the up-down direction may be formed over the coupling member  200 , and the pillar member  300  connected to the roof side of the vehicle may be connected to the penetrating coupling groove  240 . 
     A plurality of coupling members  200  and pillar members  300  may be provided to be spaced apart from each other in the front-rear direction of the vehicle to the pair of side sills  100 , and the number of coupling members  200  and pillar members  300  may be determined according to the length or type of vehicle. 
     An upper end of the pillar member  300  is connected to the roof member or roof side so that the pillar members  300  coupled to the side sills  100  on either side may be connected to each other to form a vehicle body. 
     The coupling member  200  and the side sill  100  may be coupled to each other by an adhesive material or welding coupling, and the pillar member  300  coupled to the coupling member  200  by insertion of the coupling member  200  into the coupling groove  240  may be fixed by the methods including a bolting coupling, an adhesive material, or the like. 
     This facilitates the coupling between the pillar member  300  and the side sill  100 , each of which is formed of members, by the coupling member  200 , thereby having the effect of cost reduction. 
     Further, when a plurality of pillar members  300  are disposed, coupling the coupling members  200  to the side sill  100  and the pillar members  300  to the coupling members  200  allows the adoption of the pillar members in various types of vehicles according to the vehicle models and front-rear lengths, thereby having the effect of excellent general-purpose applicability. 
     The coupling member  200  may be formed with a protrusion portion  230  protruding from an inner surface toward the center of the coupling groove  240 , and the pillar member  300  may be formed with an insertion portion  310  into which the protrusion portion  230  is inserted in a shape corresponding to the protrusion portion  230  at a lower end portion. 
     As shown in  FIG.  6   , the protrusion portion  230  may protrude from an inner perimetric surface toward the center of the coupling groove  240  and extend as much as the coupling groove  240  extends in the up-down direction, and the pillar member  300  may be formed with an insertion portion  310  indented to correspond to the coupling groove  240  and configured to extend in the length direction at a lower end portion. 
     This has the effect of guiding the insertion of the pillar member  300  into the coupling groove  240  while the pillar member  300  moves downward as the protrusion portion  230  is inserted into the insertion portion  310  when the pillar member  300  is inserted into the coupling groove  240 , and has the effect of improving the bearing capacity with which the coupling member  200  supports the pillar member  300  in the direction in which the protrusion portion  230  crosses the length direction of the pillar member  300  as the protrusion portion  230  is inserted into the insertion portion  310 . 
     The protrusion portion  230  is formed such that the cross-sectional area expands in the protruding directions and may be fitted into the insertion portion  310  concurrently when the pillar member  300  is inserted downward into the coupling groove  240  from above. 
     As shown in  FIG.  6   , the protrusion portion  230  may be formed to expand in the direction in which the cross-section thereof extends. 
     This has the effect of supporting the pillar member  300  in the direction crossing the extending direction of the protrusion portion  230 , which has the effect of supporting rotational stress of the pillar member  300  and the effect of improving coupling force between the coupling member  200  and the pillar member  300 . 
     Further, the cross-sectional area of the protrusion portion  230  may expand such that the two sides are symmetrical. 
     Accordingly, the protrusion portion  230  expands in both directions crossing the protruding direction, thereby having the effect of supporting the torsional torque of the pillar member  300  in both directions. 
     Further, a plurality of protrusion portions  230  and insertion portions  310  are formed to be spaced apart from each other on the inner perimetric surface of the coupling groove  240 , thereby having the effect of improving the coupling force between the pillar member  300  and the coupling member  200 . 
     The coupling member  200  may include a rib  220  formed inside and configured to extend in a direction crossing the coupling groove  240  that extends in the up-down direction and to connect the coupling groove  240  to the outer surface of the coupling member. 
     As shown in  FIG.  6   , the coupling member  200  may be formed with an inner space inside to reduce the weight of the coupling member  200  and may be formed with the rib  220  positioned in the inner space to connect an outer surface of the coupling member  200  to an outer perimetric surface of the coupling groove  240  positioned inside the coupling member  200 . 
     This has the effect of reducing the weight of the coupling member  200  and improving the rigidity of the coupling member  200  at the same time. 
     The coupling member  200  may be formed with a first injection hole  250  that penetrates the coupling groove  240  from the outside and through which an adhesive material is injected. 
     As shown in  FIG.  7   , the coupling member  200  may be formed with the first injection hole  250  penetrating the coupling groove  240  from the outer surface. 
     The adhesive material may be injected into the coupling groove  240  through the injection hole, and the adhesive material may be an adhesive material such as epoxy that is capable of coupling metals. 
     Accordingly, by guiding the flow of the adhesive material inside the injection hole in a state where the pillar member  300  is inserted into the coupling groove  240  of the coupling member  200 , embodiments of the present invention may have the effect of applying the adhesive material to the inside of the coupling groove  240  for coupling the coupling member  200  with the pillar member  300 , without separately applying the adhesive material to the side surface of the pillar member  300  and the inner surface of the coupling groove  240  of the coupling member  200 . 
     The coupling member  200  may be formed with a second injection hole  210  that penetrates in the up-down direction and through which the adhesive material is injected to the bottom of the coupling member  200 . 
     When the coupling member  200  is coupled to the side sill  100 , the outside of the bottom is first coupled by welding coupling, and then, the adhesive material may be moved and applied to the bottom of the coupling member  200  through the second injection hole  210 . 
     This allows the firm fixing of the coupling member  200  to the side sill  100  and has the effect of facilitating the application of the adhesive material to the bottom of the coupling member  200 . 
     Further, as shown in  FIG.  5   , a plurality of second injection holes  210  may be formed and may be connected to the rib  220  to be fixed. 
     The second injection hole  210  may include an opening portion  211  in which a part of the outer surface is open. 
     As shown in  FIG.  5   , a part of the outer surface of the second injection hole  210  may be open to form the opening portion  211 , and the adhesive material may flow downward along the part in which the inner circumferential surface of the second injection hole  210  is formed. 
     That is, when the adhesive material is injected through the second injection hole  210 , the inside air escapes through the opening portion  211 , thereby having the effect of the adhesive material easily flowing to the bottom of the coupling member  200 . 
     The coupling member  200  and the pillar member  300  may be coupled to each other by bolting a bolt V inward from the outside in a direction crossing the length direction of the pillar member  300 . 
     As shown in  FIG.  6   , the pillar member  300  may be inserted into the coupling groove  240  of the coupling member  200  to be coupled to the coupling member  200 , and then, may be fixed by bolting coupling by inserting the bolt V in the direction crossing the length direction of the pillar member  300  from the outside of the coupling member  200 . 
     The adhesive material is injected through the first injection hole  250  to fix the pillar member  300  to the coupling member  200  after the pillar member  300  is fixed to the coupling member  200  by bolting coupling, thereby having the effect of double fixing the pillar member  300  to the coupling member  200 . 
     The upper surface of the coupling member  200  may be formed to incline upward from the inside to the outside of the vehicle. 
     As shown in  FIGS.  4  and  5   , the upper surface of the coupling member  200  may be formed to incline upward from the inside to the outside of the vehicle so that the outer surface of the coupling member  200  may be higher. 
     The outer surface of the coupling member  200  is formed to be higher so that rigidity may be improved to better protect the pillar member  300  and the side sill  100  in the event of a collision, and further, the inclination may be set at various angles in consideration of the rigidity and the like. 
     As shown in  FIG.  8   , the coupling member  200  may include a cover  260  formed to cover the upper surface. 
     The coupling member  200  may be formed by injection molding in a shape with an open-top so as to form the rib  220  and the coupling groove  240  inside. 
     Accordingly, there is a concern that an external foreign material may be introduced into the inner space and there is the problem that the introduction of an external foreign material renders the adhesion by an adhesive material difficult. 
     In order to resolve the issue, the cover  260  covering the upper surface of the coupling member  200  may be provided to prevent foreign material from being introduced inside. 
       FIG.  9    is a perspective view showing the coupling member  200 , a connecting member  400 , and the pillar member  300  of a vehicle body coupled to each other according to still another embodiment of the present invention;  FIG.  10    is a longitudinal view of a connecting member taken along the line B-B in  FIG.  9   ;  FIG.  11    is a perspective view showing the coupling member  200 , the connecting member  400 , and the pillar member  300  of a vehicle body coupled to each other viewed from the outside of the vehicle according to still another embodiment of the present invention;  FIG.  12    is a view showing the connecting member  400  according to still another embodiment of the present invention; and  FIG.  13    is a longitudinal view showing the connecting member taken along the line C-C in  FIG.  12   . 
     Still another embodiment of a vehicle body according to embodiments of the present invention will be described with reference to  FIGS.  9  to  13   . 
     The connecting member  400  which extends in the up-down direction to be inserted into the coupling groove  240  and which connects the pillar member  300  to the coupling member  200  by the insertion of the lower end portion of the pillar member  300  into a through groove  430  provided to penetrate in the up-down direction may be further included. 
     As shown in  FIG.  9   , the connecting member  400  extending in the up-down direction of the vehicle may be inserted into the coupling groove  240  of the coupling member  200  and the pillar member  300  may be inserted into the through groove  430  penetrating in the up-down direction of the connecting member  400  so that the pillar member  300 , the connecting member  400 , and the coupling member  200  may be coupled to each other. 
     This has the effect of minimizing the height difference between the coupling member  200  and the pillar member  300  and has the effect of improving rigidity with which the lower portion of the pillar member  300  is supported in the lateral and vertical directions of the vehicle. 
     Further, the connecting member  400  may be coupled to the pillar member  300  with an adhesive material or by welding coupling. 
     The coupling member  200  may be formed with the first injection hole  250  that penetrates the coupling groove  240  from the outside and through which the adhesive material is injected, and the connecting member  400  may be provided with a first guide groove  410  inclined downward and indented from the outer surface of the coupling member  200  at a position where the adhesive material is introduced from the first injection hole  250  to guide the flow of the adhesive material. 
     As shown in  FIG.  9   , the adhesive material is injected through the first injection hole  250  that penetrates the coupling groove  240  from the outside of the coupling member  200  to inject the adhesive material into the coupling groove  240 , the connecting member  400  is provided with the first guide groove  410  formed to be indented from the outer perimetric surface and inclined downward to guide the flow of the injected adhesive material, and the first guide groove  410  is formed around the outer perimetric surface of the connecting member  400 , thereby having the effect of guiding the flowing direction of the adhesive material so that the adhesive material spreads over the entire outer perimetric surface. 
     The connecting member  400  may include a first flow hole  420  that penetrates the through groove  430  at a lower end portion of the first guide groove  410  and through which the adhesive material flowing from the first guide groove  410  is injected into the through groove  430 , and a second guide groove  460  connected to the first flow hole  420  and indented outward from the inner surface of the through groove  430  to guide the flow of the adhesive material flowing in the first flow hole  420 . 
     As shown in  FIG.  10   , in order to introduce the adhesive material of which the flow is guided by the first guide groove  410  into the through groove  430 , the first flow hole  420  penetrating the lower end portion of the first guide groove  410  is formed so that the adhesive material may flow into the through groove  430  through the first flow hole  420 . 
     This allows the coupling of the connecting member  400  to the pillar member  300  by an adhesive material. 
     Further, the second guide groove  460  that guides the flow of the adhesive material introduced into the through groove  430  through the first flow hole  420  so that the adhesive material flows inside the through groove  430  is formed to be indented outward from the inside of the through groove  430  such that the adhesive material flows along the second guide groove  460 , thereby having the effect of coupling the pillar member  300  to the connecting member  400 . 
     The connecting member  400  may include a second flow hole  440  formed to penetrate the through groove  430  at a position corresponding to the first injection hole  250 , and a third guide groove  450  connected to the second flow hole  440  and indented outward from the inner surface of the third insertion groove to guide the flow of the adhesive material flowing into the second flow hole  440 . 
     As shown in  FIGS.  11  to  13   , the second flow hole  440  through which the adhesive material injected into the first injection hole  250  is injected into the through groove  430  may be formed at the position corresponding to the first injection hole  250 , and the adhesive material flows along the third guide groove  450  connected to the second flow hole  440  and is formed to be indented outward from the inside of the through groove  430 , thereby having the effect of coupling the pillar member  300  to the connecting member  400 . 
       FIGS.  14 A and  14 B  are views showing still another embodiment of the present invention. 
     As shown in  FIGS.  14 A and  14 B , it may be confirmed that the inclination angle at the top of the coupling member may be varied according to the rigidity setting of the coupling member. 
       FIGS.  15  and  16    are views showing various manufacturing processes of a vehicle body according to an embodiment of the present invention. 
       FIGS.  15  and  16    show the manufacturing processes of embodiments of the present invention to which the connecting member  400  is applied.  FIG.  15    shows a first manufacturing process and a second manufacturing process of embodiments of the present invention, and  FIG.  16    shows a third manufacturing process of embodiments of the present invention. 
     The first manufacturing process of embodiments of the present invention may couple the connecting member  400  to the coupling member  200  by an adhesive material and then couple the coupling member to the side sill  100  by welding coupling. Thereafter, the pillar member  300  is inserted into the connecting member  400  and the pillar member  300 , the connecting member  400 , and the coupling member  200  may be coupled to each other by an adhesive material at a high temperature through a separate heating process. The first manufacturing process has the advantage of strong coupling strength. 
     The second manufacturing process is the same as the first manufacturing process up to welding of the coupling member  200  to the side sill  100 , and insertion of the pillar member  300  into the connecting member  400 , fixing by an adhesive material at the room temperature at the time of fixing, and a separate mechanical coupling such as bolting may be added. Compared with the first manufacturing process, the second manufacturing process has the advantage of simplifying the manufacturing process by eliminating the heating process. 
     The third manufacturing process may couple the pillar member  300  and the connecting member  400  to the coupling member  200  at the same time by coupling the coupling member  200  to the side sill  100  by welding coupling and injecting the adhesive material through the first injection hole  250  formed in the coupling member  200  to the connecting member  400  and the pillar member  300 . Compared with the first and second manufacturing processes, the third manufacturing process has the advantage of simplifying the coupling process. 
     The specific embodiments of the present invention are illustrated and described, but it will be self-evident to those skilled in the art that the present invention may be improved upon and modified in various ways within the scope not departing from the technical spirit of the present invention provided by the patent claims below.
