[0002] In the case of a conventional monocoque vehicle body, a plurality of components are connected to each other in a complex structure to construct the vehicle body. The shape and connection connection structure of the components are different for each vehicle type.

[0003] Therefore, in order to construct the body of a vehicle model, a plurality of dies are required to manufacture the components for constructing the body. In addition, since the die cannot be used together to construct the body of another vehicle model, another set of dies should be manufactured.

[0004] As described above, in the case where a vehicle body is manufactured according to a different assembly structure for each vehicle model and a plurality of components are used, workability is reduced.

[0005] The foregoing content is only intended to help understand the background of the present disclosure, but is not intended to indicate that the present disclosure falls within the scope of the prior art already known to those skilled in the art. Summary of the invention

[0006] The present disclosure generally relates to a connection structure of a vehicle body, and a specific embodiment relates to a connection structure of an upper portion of a rear pillar (C-pillar).

[0007] Therefore, an embodiment of the present disclosure provides a connection structure of a vehicle body, which is configured so that when a modular space frame vehicle body is constructed, components corresponding to the rear pillars (C-pillars) of the vehicle can be easily assembled to the roof and the vehicle floor, and can be connected thereto with excellent strength and rigidity.

[0008] According to one embodiment of the present disclosure, a connection structure of a vehicle body is provided. The connection structure includes: a roof side beam member extending in the longitudinal direction of the vehicle body; a roof rear cross beam extending in the transverse direction of the vehicle body, the end of which is connected to the rear end of the roof side beam member; a rear pillar member extending in the vertical direction of the vehicle body, the upper part of which is connected to the rear end of the roof side beam member and aligned with the end of the roof rear cross beam member; and a covering bracket covering the portion where the rear end of the roof side beam member, the end of the roof rear cross beam member and the upper part of the rear pillar member are connected to each other, the covering bracket being integrated with a portion in a single vehicle body.

[0009] The upper portion of the rear pillar member may be directly coupled and connected to the rear end of the roof side rail member.

[0010] The structure in which the upper portion of the rear pillar member is directly coupled to the rear end of the roof side member may be a structure configured such that the upper end of the rear pillar member may extend in a straight line along the longitudinal direction of the roof side member, and its upper end surface may be directly coupled to the rear end of the roof side member. The structure in which the upper portion of the rear pillar member is directly coupled to the rear end of the roof side member may be a structure configured such that the upper end of the rear pillar member may be provided as a reinforcing portion that may be bent along the longitudinal direction of the roof side member, and the reinforcing portion may be coupled to the rear end of the roof side member in a surface contact manner.

[0011] When the upper portion of the rear pillar member is directly coupled to the rear end of the roof side member, a first reference line passing through the center of the connecting structure along the longitudinal direction of the roof side member, a second reference line passing through the center of the connecting structure along the longitudinal direction of the roof rear cross member, and a third reference line passing through the center of the connecting structure along the longitudinal direction of the rear pillar member may be connected together to intersect at one point.

[0012] The upper portion of the rear pillar member may be connected to the rear end of the roof side member through a cover bracket while being spaced apart from the rear end of the roof side member.

[0013] The structure in which the upper portion of the rear pillar member is connected to the rear end of the roof side member through the covering bracket while being spaced apart from the rear end of the roof side member may be a structure configured so that the upper end of the rear pillar member extending in a straight line along the longitudinal direction of the roof side member can be connected to the rear end of the roof side member through the covering bracket while being spaced apart from the rear end of the roof side member. The structure in which the upper portion of the rear pillar member is connected to the rear end of the roof side member through the covering bracket while being spaced apart from the rear end of the roof side member may be a structure configured so that the upper end of the rear pillar member can be provided as a reinforcing portion that can be bent along the longitudinal direction of the roof side member, and the reinforcing portion can be connected to the rear end of the roof side member through the covering bracket while being spaced apart from the rear end of the roof side member.

[0014] The covering bracket may include: a first covering bracket, which is arranged inside the vehicle body to integrally cover the rear end of the roof side beam member, the end of the roof rear cross beam member and the upper part of the rear pillar member; a second covering bracket, which is arranged outside the vehicle body to integrally cover the rear end of the roof side beam member and the end of the roof rear cross beam member; and a third covering bracket, which is arranged outside the vehicle body to integrally cover the rear end of the roof side beam member and the upper part of the rear pillar member.

[0015] The second cover bracket and the third cover bracket may be coupled to each other without a gap therebetween because the second cover bracket and the third cover bracket contact each other at the roof side member outside the vehicle body and are connected to each other in a surface contact manner.

[0016] The first cover bracket and the third cover bracket may be disposed to overlap each other to provide a flange portion having a predetermined area. The flange portion may be disposed at a portion between a rear end of the roof side member and an upper portion of the rear pillar member.

[0017] When a reinforcement portion bendable in the longitudinal direction of the roof side member is provided at the upper end of the rear pillar member, the flange portion may be provided to integrally cover the reinforcement portion.

[0018] According to an embodiment of the present disclosure, when constructing a modular space frame body, a rear pillar member corresponding to the rear pillar (C-pillar) of the vehicle can be easily connected to the roof and floor of the body with an easy assembly process and excellent strength and rigidity. Therefore, the connection structure of the embodiment of the present disclosure can ensure a strong connection force, strength and rigidity, and can improve durability.

[0027] Hereinafter, a connection structure of a vehicle body according to an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0028] Figure 1 is a view showing a modular space frame vehicle body. Figure 1 , the floor assembly 109 includes a front apron assembly 101, an instrument panel assembly 103, a center floor assembly 105, and a rear floor assembly 107. The upper assembly 119 includes a side assembly 111, a quarter assembly 113, a rear assembly 115, and a roof rack 117. When the floor assembly 109 and the upper assembly 119 are assembled, a skin assembly 127 including a fender 121, a side outer portion 123, and a roof panel 125 is coupled thereto to form a space frame body.

[0029] For reference, the above Figure 1 The description of the drawings in the figures is only for easy understanding of the configuration of the space frame body mentioned in the present disclosure, and it does not represent the assembly order of the carriages constituting the actual space frame body. The actual assembly order may vary depending on various circumstances.

[0030] The roof rack 117 includes a roof side tube 129, a dash panel 131, a center roof rail 133, and a rear roof rail 135 forming a space frame structure. The roof side tube 129 is located at opposite sides of the vehicle, and the dash panel 131, the center roof rail 133, and the rear roof rail 135 disposed between the roof side tubes 129 to connect the roof side tubes 129 to each other are formed into a hollow closed tube structure. As the roof side tube 129 expands and contracts in the longitudinal direction of the vehicle body, and the dash panel 131, the center roof rail 133, and the rear roof rail 135 expand and contract in the transverse direction of the vehicle body, the roof rack 117 is easily deformed and applied to various vehicle types and various vehicle models.

[0031] The front fender assembly 101, the instrument panel assembly 103, the center floor assembly 105, and the rear floor assembly 107, which are modularized to form the floor assembly 109, are assembled by changing their length or width. Therefore, the floor assembly 109 is easily deformed and applied to various vehicle types and various vehicle models.

[0032] As the roof frame 117 and the floor assembly 109 are deformed, other components can be assembled by adjusting their shapes or sizes. Therefore, it is easy to develop a body suitable for a new vehicle type or model, thereby facilitating the development of a new vehicle type, and the body structure can be effectively applied to small-volume production.

[0033] Meanwhile, the skin assembly 127 including the fender 121, the side outer portion 123, and the roof panel 125 may be made of various materials such as carbon fiber reinforced plastic (CFRP) as well as conventional steel plastic. Therefore, each shape of the assembly may be freely changed according to the vehicle type or vehicle model to be applied to the above-mentioned space frame, and various vehicles may be easily manufactured.

[0034] The connection structure for a vehicle body may be configured to be applied to a space frame vehicle body having the above configuration. Figure 2 and Figure 3 As shown in the embodiment of the present invention, the connection structure for the vehicle body includes: a roof side member 10 extending in the longitudinal direction of the vehicle body; a roof rear cross member 20 extending in the transverse direction of the vehicle body and having its end connected to the rear end of the roof side member 10; a rear pillar member 30 extending in the vertical direction of the vehicle body and having its upper portion connected to the rear end of the roof side member 10 while being aligned with the end of the roof rear cross member 20; and a cover bracket 40 formed in a plate shape, which covers the portion where the rear end of the roof side member 10, the end of the roof rear cross member 20 and the upper portion of the rear pillar member 30 are connected to each other, and the cover bracket 40 is integrated with a portion in a single vehicle body.

[0035] That is, the roof side member 10 is inserted between the roof rear cross member 20 and the rear pillar member 30, and the roof rear cross member 20 and the rear pillar member 30 are respectively connected at right angles to the roof side member 10. In addition, the cover bracket 40 covers and reinforces the portion where the rear end of the roof side member 10, the end of the roof rear cross member 20, and the upper portion of the rear pillar member 30 are connected to each other, thereby configuring a connection structure of the vehicle body.

[0036] The roof side rail member 10, the roof rear cross member 20, and the rear pillar member 30 may all be formed as hollow tubes or pipes to constitute a space frame structure.

[0037] exist Figure 1 , the roof side rail member 10 may be a configuration corresponding to the roof side pipe 129 , and the roof rear cross member 20 may be a configuration corresponding to the rear roof rail 135 .

[0038] In addition, the rear pillar member 30 may correspond to a component referred to as a C-pillar or a rear support pillar of a general vehicle.

[0039] like Figure 1 As shown, rear pillar member 30 may be aligned with and connected to a portion at a rear end of roof side tube 129, for example, a portion connected to rear roof rail 135, and cover bracket 40 may be coupled to the space frame structure to cover a connection portion where the above three components are connected to each other.

[0040] Furthermore, a connection structure of the vehicle body may be used so that the rear pillar member 30 is connected to a connection structure such as Figure 1 An object in the floor assembly 109.

[0041] That is, the connection structure may correspond to a structure in which the lower end of the rear pillar member 30 is coupled to the rear end of the side beam located at the side of the floor assembly 109 .

[0042] The floor assembly 109 as described above may be provided with a cross member which is different from the above assembly and is formed in the transverse direction of the vehicle body. Figure 1 The rear roof beam 135 in the roof frame 117 corresponds to the rear roof beam 135 in the roof frame 117. Figure 2 The connection structure of the vehicle body of FIG. 1 is used as the same structure in which the rear pillar member 30 is coupled to the rear end of the side member of the floor assembly 109 while only the direction of the connection structure is changed upside down.

[0043] In fact, the embodiment of the present disclosure is expressed with a concept including when the rear pillar member 30 is coupled to the rear end of the roof side pipe 129 and when coupled to the rear end of the side member of the floor assembly 109, as described above. That is, the connection structure of the vehicle body of the present disclosure can be commonly used in the structure in which the rear pillar member 30 formed in the vertical direction of the vehicle body is coupled to the upper side and the lower side of the vehicle body.

[0044] According to the embodiment of the present disclosure, the roof rear cross member 20 is disposed in the transverse direction of the vehicle body perpendicular to the roof side members 10. The end of the roof rear cross member 20 is connected to the roof side members 10 in a manner directly coupled to the rear end of the roof side members 10.

[0045] The coupling between the roof rear cross member 20 and the roof side rail member 10 may be performed by welding, a structural adhesive, or a separate coupling member.

[0046] Since the end portion of the roof rear cross member 20 and the rear end of the roof side member 10 are directly coupled to each other, the coupled portion between the roof rear cross member 20 and the roof side member 10 may provide sufficient strength and rigidity.

[0047] According to an embodiment of the present disclosure, the rear pillar member 30 is disposed at a right angle in the vertical direction of the vehicle body relative to the roof side member 10. The upper portion of the rear pillar member 30 can be directly coupled to the rear end of the roof side member 10 in a manner that the upper portion of the rear pillar member 30 is aligned with the end of the roof rear cross member 20.

[0048] The coupling between the rear pillar member 30 and the roof side rail member 10 may be performed by welding, a structural adhesive, or a separate coupling member.

[0049] As described above, the structure in which the upper portion of the rear pillar member 30 is directly coupled to the rear end of the roof side member 10 may be one of the following structures. That is, there may be a structure in which the upper end of the rear pillar member 30 extends in a straight line along the longitudinal direction of the roof side member 10, and the upper end surface of the rear pillar member 30 is directly coupled to the rear end of the roof side member 10, such as Figure 2 Alternatively, there may be a structure in which the upper end of the rear pillar member 30 is provided as a reinforcement portion 31 bent along the longitudinal direction of the roof side member 10, and the reinforcement portion 31 is coupled to the rear end of the roof side member 10 in a surface contact manner, as shown in FIG. Figure 4 shown.

[0050] like Figure 2 As shown, when the upper end of the rear pillar member 30 is directly connected to the rear end of the roof side member 10, or as shown in Figure 4 As shown, when the rear pillar member 30 is coupled to the rear end of the roof side member 10 by the reinforcement portion 31 bent into an L shape at the upper end of the rear pillar member 30, this structure can provide sufficient strength and rigidity with respect to the coupling portion between the upper portion of the rear pillar member 30 and the rear end of the roof side member 10.

[0051] like Figure 2 and Figure 4 As shown, in the case of a structure in which the upper portion of the rear pillar member 30 is directly coupled to the rear end of the roof side member 10, a first reference line L1 passing through the center of the connection structure along the longitudinal direction of the roof side member 10, a second reference line L2 passing through the center of the roof rear cross member 20 along the longitudinal direction thereof, and a third reference line L3 passing through the center of the rear pillar member 30 along the longitudinal direction thereof are connected together to intersect at a point P1. Therefore, the strength and rigidity of the coupling portion between the roof side member 10, the roof rear cross member 20, and the rear pillar member 30 can be increased, and specifically, the load can be appropriately distributed in various directions, thereby improving durability.

[0052] That is, the roof side member 10, the roof rear cross member 20 and the rear pillar member 30 are connected together so that one end of the second reference line L2 and one end of the third reference line L3 intersect the first reference line L1 at the point P1.

[0053] As another embodiment, the structure may be configured so that the upper portion of the rear pillar member 30 can be spaced apart from the roof side rail member 10 in an arrangement aligned with the end of the roof rear cross member 20. Figure 5 and Figure 6 As shown, the upper portion of the rear pillar member 30 may be connected to the roof side rail member 10 via a cover bracket 40 .

[0054] The structure in which the upper portion of the rear pillar member 30 is spaced apart from the roof side member 10 and connected thereto through the cover bracket 40 is preferably applied to a structure requiring low rigidity or a structure requiring medium rigidity, in which case its weight and manufacturing cost can be reduced.

[0055] As described above, the structure in which the upper portion of the rear pillar member 30 is spaced apart from the rear end of the roof side member 10 and connected thereto by the cover bracket 40 may be one of the following structures. There may be a structure in which the upper end of the rear pillar member 30 extending in a straight line in the longitudinal direction of the roof side member 10 is spaced apart from the rear end of the roof side member 10 by a predetermined gap G1 and connected thereto by the cover bracket 40, as shown in FIG. Figure 5 Alternatively, there may be a structure in which the upper end of the rear pillar member 30 is provided as a reinforcement portion 31 bent along the longitudinal direction of the roof side member 10, and the reinforcement portion 31 is spaced apart from the rear end of the roof side member 10 by a predetermined gap G2 and connected to the roof side member 10 through the cover bracket 40, as shown in FIG. Figure 6 shown.

[0056] like Figure 5 As shown, such a structure is preferably applied to reduce weight and manufacturing cost in a structure requiring low rigidity, and the structure is configured so that the upper end of the rear pillar member 30 extending in a straight line in the longitudinal direction of the roof side member 10 is spaced apart from the rear end of the roof side member 10 by a predetermined gap G1 and connected thereto through the cover bracket 40.

[0057] like Figure 6 As shown, such a structure is preferably applied to reduce weight and manufacturing cost in a structure requiring medium rigidity, and the structure is configured such that a reinforcement portion 31 bent into an L-shape at the upper end of a rear pillar member 30 is spaced apart from the rear end of the roof side member 10 by a predetermined gap G2 and connected thereto through a cover bracket 40.

[0058] With no Figure 5 Compared with the structure of the reinforcement portion 31, Figure 6 The structure in which the reinforcement portion 31 is provided at the rear pillar member 30 can ensure relatively greater strength and rigidity of the upper portion of the rear pillar member 30 .

[0059] The covering bracket 40 of the embodiment of the present disclosure includes a first covering bracket 41, which is arranged inside the vehicle body to integrally cover the rear end of the roof side beam member 10, the end of the roof rear cross beam member 20 and the upper part of the rear pillar member 30; a second covering bracket 42, which is arranged outside the vehicle body to integrally cover the rear end of the roof side beam member 10 and the end of the roof rear cross beam member 20; and a third covering bracket 43, which is arranged outside the vehicle body to integrally cover the rear end of the roof side beam member 10 and the upper part of the rear pillar member 30.

[0060] That is, the first covering bracket 41, the second covering bracket 42, and the third covering bracket 43 provide support by covering the connection portion between the rear end of the roof side member 10, the end of the roof rear cross member 20, and the upper portion of the rear pillar member 30 in a surface contact manner in all directions. Therefore, the connection portion can provide sufficient strength and rigidity.

[0061] The outer edge of the second cover bracket 42 and the outer edge of the third cover bracket 43 contact each other at the roof side member 10 outside the vehicle body and are connected to each other in a surface contact manner. The second cover bracket 42 and the third cover bracket 43 are coupled to each other without a gap therebetween. Therefore, the second cover bracket 42 and the third cover bracket 43 can have a stronger coupling force.

[0062] When the first covering bracket 41, the second covering bracket 42 and the third covering bracket 43 cover the connecting parts where the end of the roof rear cross member 20, the upper part of the rear pillar member 30 and the rear end of the roof side member 10 are connected to each other, the first covering bracket 41, the second covering bracket 42 and the third covering bracket 43 forming the covering bracket 40 can be connected to the connecting structure by welding or fixing with a structural adhesive.

[0063] The first cover bracket 41 and the third cover bracket 43 are arranged to overlap each other, thereby providing a flange portion 44 having a predetermined area. The flange portion 44 is configured as a portion provided between the rear end of the roof side member 10 and the upper portion of the rear pillar member 30. Therefore, the connection portion between the rear end of the roof side member 10 and the upper portion of the rear pillar member 30 can have improved strength and rigidity.

[0064] Furthermore, the flange portion 44 is provided to integrally cover the reinforcement portion 31 bent in the longitudinal direction of the roof side member 10 at the upper end of the rear pillar member 30. Therefore, the reinforcement portion 31 can be provided with sufficient coupling strength and rigidity.

[0065] The connection structure of the vehicle body as described above is configured so that the vertical length of the rear pillar member 30 can be easily changed and connected to the rear end of the roof side member 10. Therefore, the connection structure can be as follows 7A to 7C The shown is easily applicable to various structures of vehicle body frames.

[0066] exist Fig. 7A Figure 7C , various structures of the vehicle body frame are shown to be compared with each other. In each structure of the vehicle body frame, circles A1 and C1 represent joints provided to form each vehicle body frame. Among the circles, the opposite ends of the components corresponding to the rear pillar member 30 of the present disclosure are represented by solid circles C1, and the above-mentioned connection structure of the vehicle body of the present invention can be applied to the solid circles C1.

[0067] That is, when the length change and slight deformation of the rear pillar member 30 are caused, the connection structure of the vehicle body can be easily commonly applied to 7A to 7C Various vehicle types are shown. Therefore, development of new vehicle types can be easily performed, and a technical infrastructure that can be effectively applied to small-volume production can be provided.

[0068] Heretofore, according to an embodiment of the present disclosure, when constructing a modular space frame type vehicle body structure, a rear pillar member 30 corresponding to a rear pillar (C-pillar) of a vehicle having easy assembly performance and excellent strength and rigidity is connected to the roof and floor of the vehicle body. Therefore, the connection structure can ensure stronger connection force, strength and rigidity, and can improve durability.

[0069] Although preferred embodiments of the present disclosure have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
