Description

Technical Field

[0001] The present disclosure relates to a vehicle body joint structure. Background Art

[0002] The pillars of a car are divided into front pillars, middle pillars and rear pillars according to their positions, and these pillars not only have the function of supporting the top of the vehicle, but also have the important function of improving the rigidity and stability of the vehicle body.

[0003] The pillar according to the prior art is a combination of several molded parts to be designed as a monocoque type (load-bearing type), and thus has high rigidity, but these molded parts can hardly be used as design parts for realizing various designs of vehicles and for common use in sections.

[0004] Obviously, in the existing monocoque structure, the entire front pillar can be designed using a stretch molded inner member and outer member, but this does not have scalability for connection with other parts and requires the development of new molds for various types and designs of vehicles.

[0005] That is, for various small-scale production and production using smart factories, many changes in design are required, and therefore, there is a problem that the number of molds increases significantly, whereby the manufacturing cost inevitably increases.

[0006] Therefore, a vehicle body having a novel structure or a novel pillar structure is required, which can overcome the defects of the prior art and ensure the expandability for connection with other parts.

[0007] The description provided above as a related art of the present disclosure is only intended to help understanding the background of the present disclosure, and should not be construed as being included in the related art known to those skilled in the art. Summary of the invention

[0008] The present disclosure relates to a vehicle body joint structure and a specific embodiment relates to a component structure connecting a vehicle body top and a pillar.

[0009] The present disclosure is directed to solving the problems in the related art, and an embodiment of the present disclosure provides a vehicle body joint structure, which generally uses a connector to connect a vehicle body roof and a pillar, thereby ensuring convenience in assembly and improving strength and rigidity by being able to apply components corresponding to the vehicle body roof and the pillar in various ways according to various types of vehicles.

[0010] In view of the foregoing, a vehicle body joint structure according to an embodiment of the present disclosure includes: a top side member extending from a side portion of an upper portion of a vehicle body in a front-to-rear direction; a pillar member extending in an up-down direction to match a front end portion or a rear end portion of the top side member; a top beam member extending laterally from an upper portion of the vehicle body to match a front end portion or a rear end portion of the top side member; and a connector disposed at the front end portion or the rear end portion of the top side member and fixing the top side member, the pillar member, and the top beam member.

[0011] The pillar member may be positioned below the front or rear end of the top side member and the top beam member may be positioned to the side of the front or rear end of the top side member, and thus the pillar member and the top beam member may be laterally spaced apart at an angle from each other.

[0012] The pillar member may be coupled to a lower portion of the front end portion or the rear end portion of the top side member, and the top beam member may be coupled to a side portion of the front end portion or the rear end portion of the top side member.

[0013] The connector may have a first seat extending in the front-rear direction to seat the top side member, a second seat extending downward from the first seat to seat the pillar member, and a third seat extending laterally from the first seat to seat the top beam member.

[0014] The first seat portion may extend in the front-rear direction with a curved shape to surround a surface of the roof side member, the second seat portion may be formed to surround the pillar member, and the third seat portion may be formed to surround the roof beam member.

[0015] The connector may have a bifurcated portion to which the first seat, the second seat, and the third seat are connected, and the first seat, the second seat, and the third seat may extend in different directions at the bifurcated portion.

[0016] The pillar member may be formed so that the end portion connected to the connector is bent in the front-rear direction, and the second seat may be formed in the same direction as the shape of the bent end portion of the pillar member so that the bent end portion of the pillar member is located in the second seat.

[0017] The connector may have a support portion which protrudes at a position where the first socket and the second socket are matched or at a position where the first socket and the third socket are matched and bifurcates the sockets.

[0018] The connector may have a panel portion extending downward from the first seat and having a region filling a space between the first seat and the second seat.

[0019] Several ribs extending in different directions and passing through the area may be formed on the panel portion of the connector.

[0020] The connector may have a reinforcing portion extending and bent along a space between the first and third seating portions, and coupled to the first and third seating portions.

[0021] The connector may include: a first part having a first mounting portion extending in a front-to-rear direction to seat a top side member and a second mounting portion extending laterally from the first mounting portion to seat a top beam member; and a second part assembled and fixed to the first part and having a third mounting portion for seating a pillar member.

[0022] An assembling protrusion may be formed at a lower portion of the first mounting portion of the first part, and an assembling groove may be formed at an upper portion of the second part, and the assembling groove is matched with the assembling protrusion.

[0023] The assembling protrusion may extend laterally and may have a rear end portion protruding in the front-rear direction, and the assembling groove may extend laterally and may be open to match the assembling protrusion.

[0024] The second portion may have flange portions extending in the front-rear direction along the first mounting portion in the third mounting portion and each having an area.

[0025] A lattice shape may be formed in other portions of the connector except for a portion where the top side member, the pillar member, and the top beam member are mounted.

[0026] The above vehicle body joint structure generally uses a connector to connect the vehicle body roof and the pillar, so that components corresponding to the vehicle body roof and the pillar can be applied in various ways according to various types of vehicles, thereby ensuring convenience in assembly and improving coupling strength and rigidity.

[0032] A vehicle body joining structure according to an embodiment of the present disclosure is described hereinafter with reference to the accompanying drawings.

[0033] Figure 1 is a view showing the structure of a vehicle body joining structure according to an embodiment of the present disclosure, Figures 2 to 7 is a view showing a first embodiment of a vehicle body joint structure according to the present disclosure, Figures 8 to 11 is a view showing a second embodiment of a vehicle body joint structure according to the present disclosure, and FIG. 12A to FIG. 12D 2 is a view showing an example when the embodiment of the present disclosure is applied to a vehicle body frame structure.

[0034] The present disclosure relates to a modular vehicle body, and in the construction of the vehicle body, for example, Figure 1 As shown, the floor assembly 10 is composed of a front assembly 11, a baffle assembly 12, a central floor assembly 13 and a rear floor assembly 14, the upper assembly 20 is composed of a front side assembly 21, a rear side assembly 22, a back assembly 23 and a top assembly 24, and the skin assembly 30 is composed of a fender 31, an outer side 32, and a top panel 33, and the skin assembly is combined with the floor assembly 10 and the upper assembly 20, thereby forming a modular vehicle.

[0035] The modular vehicle body is an embodiment provided only to facilitate modularization of the vehicle body, and the assembly sequence and components may be changed when forming an actual vehicle.

[0036] The embodiment of the present disclosure relates to a roof side member 100 and a roof beam member 300 constituting a roof assembly, and a connector 400 connecting a pillar member 200 to the roof side member and the roof beam member. The roof side member 100, the roof beam member 300, and the connector 400 connecting the pillar member 200 to the roof side member and the roof beam member all have a hollow closed cross-section, thereby forming a space frame structure. Therefore, by adjusting the length, the roof side member 100, the pillar member 200, and the roof beam member 300 can be easily applied to various types and models of vehicles.

[0037] When the shapes of the roof side member 100, the pillar member 200, and the roof beam member 300 are changed in this manner, the shapes or sizes of other parts connected to these members can be adjusted. Therefore, a vehicle body suitable for various types and models of vehicles can be developed, a new type of vehicle can be developed more easily, and the present disclosure can be effectively applied to small-scale production of various types of products.

[0038] A vehicle body joint structure according to an embodiment of the present disclosure relates to Figure 1The component A shown in the figure is connected to the top side member 100, the pillar member 200 and the top beam member 300, and includes the top side member 100 extending from the side of the upper part of the vehicle body in the front-rear direction, the pillar member 200 extending in the up-down direction to match the front end or the rear end of the top side member 100, the top beam member 300 extending transversely from the upper part of the vehicle body to match the front end or the rear end of the top side member 100, and the connector 400, which is provided at the front end or the rear end of the top side member 100 and fixes the top side member 100, the pillar member 200 and the top beam member 300.

[0039] like Figures 2 to 5 As shown, the roof side member 100, the pillar member 200, and the roof beam member 300 are connected by the connector 400. That is, the roof side member 100 extending in the front-rear direction from the side of the upper portion of the vehicle body, the pillar member 200 extending in the up-down direction and forming the A-pillar or the C-pillar, and the roof beam member 300 connecting the roof side member 100 at both sides are connected by the connector 400, whereby even if the roof side member 100, the pillar member 200, and the roof beam member 300 are changed according to the type and model of the vehicle, a modular vehicle body can be realized by the connector 400.

[0040] As described above, the pillar member 200 is positioned below the front end or rear end of the top side member 100 extending in the forward direction, and the top beam member 300 is positioned at the side of the front end or rear end of the top side member 100. As described above, the top side member 100 is coupled to the connector 400, the pillar member 200 is coupled to the lower portion of the top side member 100, and the top beam member 300 is connected to the side of the top side member 100, thereby ensuring the rigidity and strength of the joint of the members. The connector 400 extends in the front-rear direction so that the top side member 100 is located on the connector, and the pillar member 200 and the top beam member 300 are spaced apart from each other at a predetermined angle around the top side member 100, thereby realizing a curved shape that can accommodate the pillar member 200 and the top beam member 300.

[0041] The top side member 100, the pillar member 200, and the top beam member 300 located on the connector 400 can be coupled to each other. That is, the pillar member 200 is coupled to the lower part of the front end or the rear end of the top side member 100, and the top beam member 300 is coupled to the side of the front end or the rear end, thereby realizing a strong coupling structure through the coupling of the members. Therefore, the rigidity and strength are ensured at the joint by the connector 400.

[0042] The coupling structure of the connector 400, the top side member 100, the column member 200, and the top beam member 300 may be implemented in various embodiments.

[0043] As an example, Figure 4 As shown, the connector 400 may have: a first seat 410 extending in the front-to-rear direction to accommodate the top side member 100; a second seat 420 extending downward from the first seat 410 to accommodate the pillar member 200; and a third seat 430 extending laterally from the first seat 410 to accommodate the top beam member 300.

[0044] As described above, the connector 400 has the first seat portion 410, the second seat portion 420, and the third seat portion 430, wherein the first seat portion 410 extends in the front-rear direction to be able to seat the roof side member 100, the second seat portion 420 extends downward from the first seat portion 410 to seat the pillar member 200, and the third seat portion 430 extends laterally from the first seat portion 410 to seat the roof beam member 300. The pillar member 200 vertically supports the vehicle body, the roof beam member 300 extends horizontally, and the second seat portion 420 on which the pillar member 200 is seated and the third seat portion 430 on which the roof beam member 300 is seated are spaced apart from each other at a predetermined angle around the first seat portion 410, and thus, the connector member may be curved.

[0045] The first seat 410 may extend in the front-rear direction with a curved shape to surround the surface of the roof side member 100 , the second seat 420 may be formed to surround the pillar member 200 , and the third seat 430 may be formed to surround the roof beam member 300 .

[0046] That is, if Figure 4 It can be seen that the first seat portion 410 is bent into an L shape to surround the surface of the top side member 100, so the top side member 100 is firmly coupled to the first seat portion 410, and the second seat portion 420 and the third seat portion 430 may have seat surfaces extending along the pillar member 200 and the top beam member 300 respectively and side surfaces bent at both sides of the seat surfaces. Therefore, the members can be firmly coupled to the seat of the connector 400.

[0047] The connector 400 has a bifurcated portion 440 to which the first, second, and third sockets 410, 420, and 430 are connected, and the first, second, and third sockets 410, 420, and 430 may extend in different directions from the bifurcated portion.

[0048] As described above, since the roof side member 100, the pillar member 200, and the roof beam member 300 are all coupled to the bifurcated portion 440 of the connector 400, the coupling is easy, and the coupling strength and rigidity are ensured. That is, the bifurcated portion 440 of the connector 400 is a portion that connects the first seat portion 410, the second seat portion 420, and the third seat portion 430, and the roof side member 100, the pillar member 200, and the roof beam member 300 are supported by the bifurcated portion 440 and matched with each other, thereby being able to form a strong vehicle joint structure.

[0049] At the same time, if Figure 5 As shown, the pillar member 200 is formed so that the end portion 200a connected to the connector 400 is bent in the front-rear direction, and the second seat portion 420 is formed in the same direction as the shape of the bent end portion of the pillar member 200 to seat the bent end portion of the pillar member 200.

[0050] As described above, since the pillar member 200 is formed so that the end portion 200a connected to the connector 400 is bent forward or backward, the contact area with the connector 400 is increased, and the coupling rigidity is ensured. Therefore, the second seat portion 420 of the connector 400 can be formed to have the same shape as the bent end portion of the pillar member 200, and when the pillar member 200 is seated on the second seat portion 420, the support strength in the front-rear direction and the up-down direction is ensured.

[0051] On the other hand, Figure 6 As shown, the connector 400 may have a support portion 417 that protrudes at a position where the first socket 410 is matched with the second socket 420 or a position where the first socket 410 is matched with the third socket 430 and causes the sockets to fork.

[0052] As described above, since the support portion 417 is formed at the connector 400, and the first seat 410 and the second seat 420 or the first seat 410 and the third seat 430 are bifurcated through the support portion 417, the pillar member 200 and the top beam member 300 are spaced apart from the top side member 100. Therefore, the pillar member 200 and the top beam member 300 are spaced apart from the top side member 100 contacting the support portion 417 rather than being coupled, and thus, the pillar member 200 or the top beam member 300 may be coupled to the top side member 100 through the connector 400. As described above, since the pillar member 200 or the top beam member 300 is coupled to the top side member 100 through the connector 400, strength and rigidity are ensured.

[0053] As from Figure 7It can be seen that the support portion 417 can be changed according to the shape of the pillar member 200. That is, when the shapes of the roof side member 100, the pillar member 200 and the roof beam member 300 are changed according to the type and model of the vehicle, the connection structure can be formed by changing the connector 400 according to the shape of the member.

[0054] On the other hand, as Figure 4 It can be seen that the connector 400 may have a panel portion 413 extending downward from the first seat 410 and having an area filling the space between the first seat 410 and the second seat 420 .

[0055] As described above, since the panel portion 413 having the area is formed at the connector 400, the strength and rigidity of the panel portion are ensured. Specifically, the pillar member 200 supporting the top assembly 24 requires large rigidity, and therefore, the support rigidity of the pillar member 200 mounted on the connector 400 can be further ensured by forming the panel portion 413 in the space between the first seat portion 410 of the connector 400 where the top side member 100 is seated and the second seat portion 420 where the pillar member 200 is seated.

[0056] A plurality of ribs 414 extending in different directions and passing through the region may be formed on the panel portion 413 of the connector 400. The thickness and shape of the plurality of ribs 414 may be changed according to the required rigidity of the connector 400, and may be formed in a polygonal or circular shape relative to the region of the panel portion 413, so that the strength and rigidity of the entire connector 400 may be ensured by ensuring the rigidity of the panel portion 413.

[0057] As described above, since the connector 400 has the panel portion 413 in the space between the first seat 410 and the second seat 420 , the strength and rigidity of the roof side member 100 and the pillar member 200 are ensured so that the roof assembly 24 can be provided as a firmly coupled structure.

[0058] On the other hand, the connector 400 may have a reinforcing portion 416 that extends and bends along the space between the first seat portion 410 and the third seat portion 430 and is coupled to the first seat portion 410 and the third seat portion 430. The reinforcing portion 416 is formed to connect the first seat portion 410 and the third seat portion 430, thereby ensuring the strength and rigidity of the first seat portion 410 and the third seat portion 430. The coupling rigidity required for the top side member 100 and the top side member 300 is smaller than the coupling rigidity of the top side member 100 and the pillar member 200, but the reinforcing portion 416 connecting the first seat portion 410 and the third seat portion 430 has a bent and extended shape and is formed on the connector 400, thereby ensuring the necessary rigidity with a minimum weight increase.

[0059] Obviously, the reinforcing portion 416 of the connector 400 may be straight instead of being curved and extended, and may adopt various shapes depending on the rigidity required when coupling the top side member 100 and the top cross beam 300, thereby ensuring the coupling rigidity of the top side member 100 and the top cross beam 300 through the connector 400.

[0060] On the other hand, as another embodiment of the connector 400, Figures 8 to 11 As shown, the connector 400 may include: a first part 400a, having a first mounting portion 450 extending in the front-to-rear direction to accommodate the top side member 100 and a second mounting portion 460 extending laterally from the first mounting portion 450 to accommodate the top beam member 300; and a second part 400b, assembled and fixed to the first part 400a and having a third mounting portion 470 for accommodating the pillar member 200.

[0061] As described above, since the connector 400 is composed of the separate first portion 400a and second portion 400b, the vehicle body can be designed more freely by changing and applying these portions to design the vehicle body.

[0062] The first part 400a has a first mounting portion 450 and a second mounting portion 460 to place the roof side member 100 and the roof beam member 300 constituting the roof assembly. That is, when the design of the vehicle body is changed, the roof side member 100 and the roof beam member 300 are also changed as the configuration of the roof assembly, so the first part 400a has the first mounting portion 450 and the second mounting portion 460 so that the roof side member 100 and the roof beam member 300 can be placed. The pillar member 200 is mounted on the second part 400b assembled to the first part 400a, and the second part 400b assembled to the first part 400a has the pillar member 200 changed according to the design of the vehicle, so that the design of the vehicle body can be changed according to the kind and type of the vehicle.

[0063] On the other hand, an assembling protrusion 453 may be formed at a lower portion of the first mounting portion 450 of the first portion 400a, and an assembling groove 476 matching the assembling protrusion may be formed at an upper portion of the second portion 400b. The first portion 400a and the second portion 400b are coupled to each other by matching the assembling protrusion 453 and the assembling groove 476, thereby ensuring ease of assembly and assembly strength.

[0064] In detail, the assembly protrusion 453 extends laterally and has a rear end protruding in the front-to-back direction, and the assembly groove 476 extends laterally and opens to match the assembly protrusion 453. Therefore, the first part 400a and the second part 400b can be simply assembled by sliding the first part and the second part under the condition that the assembly protrusion 453 and the assembly groove 476 match each other. In addition, since the assembly protrusion 453 protrudes downward from the first part 400a and has a rear end protruding in the front-to-back direction, they are formed into an inverted T-shape. The assembly groove 476 is also formed into the same inverted T-shape to match the assembly protrusion 453, whereby the second part 400b can be assembled to the first part 400a by sliding the second part 400b laterally, thereby ensuring the rigidity in the front-to-back direction when the first part 400a and the second part 400b are assembled.

[0065] On the other hand, the second portion 400 b may have flange portions 473 extending in the front-rear direction along the first mounting portion 450 in the third mounting portion 470 and each having an area.

[0066] As described above, since the flange portions 473 each having an area are formed on the second portion 400b, the strength and rigidity of the second portion 400b are ensured. Specifically, since the pillar member 200 supporting the top side member 100 and the top beam member 300 constituting the top assembly requires high rigidity, the flange portion 473 is formed on the second portion 400b, thereby ensuring the support rigidity of the first portion 400a mounted on the second portion 400b. A plurality of ribs 474 extending in different directions and intersecting the area may be formed on the flange portion 473, and the thickness and shape of the plurality of ribs 474 may be changed according to the rigidity required by the second portion 400b.

[0067] On the other hand, the lattice shape 480 may be formed in other portions except for the portion where the roof side member 100 , the pillar member 200 , and the roof beam member 300 are mounted in the connector 400 .

[0068] As described above, since the lattice-shaped cross-section is formed in the other parts except the part where the top side member 100, the pillar member 200, and the top beam member 300 are installed in the connector 400, the overall rigidity is ensured. Since the lattice shape avoids appearing in the part where the top side member 100, the pillar member 200, and the top beam member 300 are installed, the coupling rigidity is not reduced when the top side member 100, the pillar member 200, and the top beam member 300 are installed on the connector 400.

[0069] The vehicle body joint structure according to the present disclosure can be generally applied to A-pillars and C-pillars. FIG. 12A to FIG. 12D, the vehicle body joint structure according to the present disclosure can be applied to the portion indicated by “■” in the vehicle body frame.

[0070] That is, the vehicle body joint structure of the embodiment of the present disclosure provides a technical basis that makes it easier to develop new vehicles by making the structure common to various vehicles, and can effectively apply the structure to produce various products on a small scale, as described above.

[0071] While the present disclosure is presented above with respect to the specific embodiments shown in the accompanying drawings, it will be apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the scope of the present disclosure described in the appended claims.
