Description

Technical Field

[0001] This disclosure relates to a closed modular frame structure for a vehicle, and more specifically, to a closed modular frame structure for a vehicle, wherein the frame structure allows the vehicle compartment to be detachably attached to the frame, allows various door components to be assembled into the PBV vehicle, and the frame structure includes a load path structure configured to disperse collision energy. Background Technology

[0002] There are many types of car doors. For example, there are swing doors, which are mainly used in passenger cars; sliding doors, which are mainly used in mid-sized vans; and hatchback doors, which are mainly used in vans and RVs.

[0003] Meanwhile, dedicated vehicles (hereinafter referred to as PBVs) are emerging as a future mode of mobility for expanding living spaces. For example, when PBVs including shoe stores and PBVs including clothing stores are parked at hubs, the hubs become shopping malls. Depending on the purpose of the PBV, its functions and design can be extensively expanded. PBVs are neither public transportation vehicles like buses nor private cars, but a new type of mobility, and they are used as flexible spaces where the purpose of the hub itself varies depending on the purpose of the PBVs parked at the hub.

[0004] Therefore, to maximize PBV utilization, a frame structure capable of adapting door types to different uses is required. For example, when space is limited, such as when only passengers exit the PBV or when the ceiling is low, sliding or opposing doors are necessary. Conversely, when loading large amounts of luggage, door types with wider openings are required. Among tailgate types, split-center and split-level "flip-top" doors require less force to open and occupy less space at the rear compared to opening and closing a single large tailgate. Flip-top doors have gained attention because the PBV opening can be widened when both the upper and lower doors are opened simultaneously.

[0005] Meanwhile, the frame structure of a typical car is configured such that, in the event of a collision, impact loads are concentrated on specific components such as the side beams. When impact loads are concentrated on specific components of the frame, there is a risk of increased vehicle damage and occupant injury.

[0006] The foregoing is intended only to help understand the background of this disclosure and is not intended to imply that this disclosure falls within the scope of prior art known to those skilled in the art. Summary of the Invention

[0007] This disclosure has been designed to solve the above-mentioned problems, and provides a closed modular frame structure for a vehicle that can apply various closed modules and compartment units to a PBV.

[0008] In addition, this disclosure provides a closed modular frame structure for a vehicle that can disperse collision energy in a car collision by applying several load path units.

[0009] The objectives of this disclosure are not limited to those described above, and other objectives not mentioned herein may be understood through the following description and will become clearer through the examples provided in this disclosure. Furthermore, the objectives of this disclosure may be achieved through the methods described in the claims and combinations thereof.

[0010] To achieve the above objectives, the closed modular frame structure of the vehicle may include the following construction.

[0011] According to an exemplary embodiment of the present invention, the enclosed modular frame structure of a vehicle may include: a platform extending from the front to the rear of the vehicle to form an external floor surface; a first compartment frame and a second compartment frame disposed on the platform such that the first compartment frame and the second compartment frame are spaced apart from each other while facing each other; at least one intermediate connecting member disposed between the first compartment frame and the second compartment frame; a load path unit contacting the first compartment frame and the second compartment frame and connected to both sides from the intermediate connecting member; and a compartment unit inserted between the load path units and fastened to the first compartment frame and the second compartment frame.

[0012] Furthermore, in the closed modular frame structure of the vehicle, the intermediate connecting component can be integrally formed with at least one of the first compartment frame and the second compartment frame.

[0013] Furthermore, in the closed modular frame structure of the vehicle, the intermediate connecting components can be integrally formed with the load path unit.

[0014] Furthermore, in the closed modular frame structure of the vehicle, at least one of the first compartment frame and the second compartment frame may further include a recess configured to accommodate an intermediate connecting component therein.

[0015] Furthermore, in the closed modular frame structure of the vehicle, the compartment unit may include: at least one load path coupling component inserted between load path units; and a compartment space component connected to the first compartment frame or the second compartment frame.

[0016] Furthermore, the vehicle's enclosed modular frame structure may further include: guide rails extending from both sides of the outer side of the platform; and compartment guiding components formed in the compartment space components at positions corresponding to and engaging with the guide rails.

[0017] Furthermore, the vehicle's enclosed modular frame structure may further include a fixing unit that secures the compartment unit to the load path unit.

[0018] Furthermore, in the closed modular frame structure of the vehicle, the fixing unit may include: a hook support member inserted into the load path unit; a hook formed on the load path unit at a position corresponding to the hook support member; and a hook insertion slot located on the load path connecting member and formed to fix the load path connecting member by receiving the hook therein.

[0019] Furthermore, the vehicle's enclosed modular frame structure may further include mounting bolts that run through both the guide rails and the compartment guidance components.

[0020] Furthermore, in the closed modular frame structure of the vehicle, when the load path connecting component and the load path unit are combined, the hook interference fits to the hook support component.

[0021] Furthermore, in the closed modular frame structure of the vehicle, the hook support component can be released from the hook when the load path coupling component is released from the load path unit.

[0022] Furthermore, the vehicle's enclosed modular frame structure may further include door components located between the first compartment frame and the second compartment frame.

[0023] This disclosure can achieve the following various effects through the combination of this embodiment and the configurations and usage relationships described below.

[0024] Because various enclosed modules and compartment units can be applied to PBV, the frame structure can be utilized depending on the application.

[0025] In addition, several load path units can be applied to disperse collision energy when a car collides, thereby reducing damage to the vehicle and ensuring passenger safety. Attached Figure Description

[0049] Reference Figure 2 According to an exemplary embodiment of the present disclosure, in the closed modular frame structure of the vehicle, at least one intermediate connecting component 300 and a load path unit 400 can be connected from front to back.

[0050] An intermediate connecting member 300 may be located between the first compartment frame 210 and the second compartment frame 220. The first compartment frame 210 and the second compartment frame 220 may be located on the platform 100. The intermediate connecting member 300 may be located on the upper side of the platform 100 between one end of the first compartment frame 210 and one end of the second compartment frame 220. More preferably, at least one intermediate connecting member 300 may be formed at a certain distance in the width direction of the vehicle. The intermediate connecting member 300 and the lower ends of the first compartment frame 210 and the second compartment frame 220 may be bolted together.

[0054] In the event of a forward collision, a load path can be formed, wherein the collision load transferred to the front load path unit 400 is transferred to the connection member with the first compartment frame 210, and the transferred collision load is transferred through the intermediate connection member 300 to the second compartment frame 220 and the rear load path unit 400. Similarly, in the event of a rearward collision, a load path can be formed, wherein the collision load transferred to the rear load path unit 400 is transferred to the connection member with the second compartment frame 220, and the transferred collision load is transferred through the intermediate connection member 300 to the first compartment frame 210 and the front load path unit 400. Multiple intermediate connection members 300 and load path units 400 can be formed to have a multi-load path structure, which distributes collision energy to multiple load paths upon collision.

[0055] Figure 3 This is a perspective view showing the case where the compartment unit 500, according to an exemplary embodiment of the present disclosure, is integrated into the load path unit 400 of the closed modular frame structure of the vehicle; and Figure 4 This is a perspective view showing the state of the compartment unit 500 combined with the load path unit 400 and the first compartment frame 210 of the closed modular frame structure of the vehicle according to an embodiment of the present disclosure.

[0056] Reference Figure 3 and Figure 4 The compartment unit 500 can be inserted between at least one load path unit 400. More preferably, the compartment unit 500 may include at least one load path connecting member 510 and a compartment space member 520. The compartment unit 500 may be located on both sides relative to the intermediate connecting member 300.

[0057] The load path coupling component 510 can be inserted between at least one load path unit 400. As an embodiment of this disclosure, see also... Figure 3 Two load path coupling components 510 can be inserted between three load path units 400. The shape of the load path coupling component 510 can correspond to the shape of the load path unit 400, so that the compartment unit 500 can be assembled without interference.

[0058] The compartment space component 520 can be connected to the first compartment frame 210 or the second compartment frame 220. When the compartment unit 500 is assembled in the vehicle, the compartment space component 520 can form the outermost surface of the vehicle's interior space. Furthermore, referring to… Figure 4 The load path unit 400 and the load path coupling component 510 can be configured to form the same plane.

[0059] Furthermore, this disclosure may include a guide rail 110 located on the platform 100 side and a compartment guide member 521 located on the compartment space member 520 side for assembling the compartment unit 500. The guide rail may be formed to extend from both sides of the outer side of the platform 100. More preferably, the guide rail 110 may extend longitudinally from the end of the platform 100 to the portion adjacent to the wheels.

[0060] This disclosure may further include a securing unit 600 for securing the compartment unit 500 to the load path unit 400. More preferably, the securing unit 600 secures the load path engagement member 510 to the load path unit 400 after the load path engagement member 510 has been fully inserted into the load path unit 400. After the securing unit 600 is released, the load path engagement member 510 is released from the load path unit 400.

[0061] Figure 5 This is a cross-sectional view showing the guide rail 110 and the compartment guide component 521 of the enclosed modular frame structure of a vehicle according to an exemplary embodiment of the present disclosure.

[0062] Reference Figure 5 The shapes of the inner circumferential surface of the guide rail 110 and the outer circumferential surface of the compartment guide component 521 can be configured to correspond to each other. When the compartment unit 500 is assembled, the compartment guide component 521 engages with the guide rail 110 to limit the amount of movement of the compartment unit 500 in the left-right direction.

[0063] According to an exemplary embodiment of this disclosure, the enclosed modular frame structure of the vehicle may further include mounting bolts 700 that completely penetrate the guide rail 110 and the compartment guide member 521. The mounting bolts 700 can be tightened to the upper surface of the guide rail 110 in the height direction. When the mounting bolts 700 are tightened, the bottom side of the compartment guide member 521 can contact the bottom side of the guide rail 110. As an embodiment of this disclosure, when the mounting bolts 700 are tightened, the compartment guide member 521 is pressed and attached to a sealing member of the guide rail 110. This limits the amount of movement of the compartment unit 500 in the height direction.

[0064] Figure 6A This is a cross-sectional view of the fixing unit 600 in the state where the load path coupling component 510 of the closed modular frame structure of the vehicle is coupled to the load path unit 400, according to an exemplary embodiment of the present disclosure.

[0065] Reference Figure 6A The fixing unit 600 may include a hook support member 610, a hook 620, and a hook insertion slot 630. The hook support member 610 can be inserted into at least one load path unit 400. The hook support member 610 may be formed as a fixing load path coupling member 510. More preferably, a groove is formed in at least one load path unit 400 such that the hook support member 610 can be assembled in the height direction. As an embodiment of the present disclosure, a cover may be formed at a position corresponding to the groove of the load path unit 400, and the groove is covered by the cover when the hook support member 610 is released. The compartment unit 500 may be selectively fixed by the fixing unit 600 and is removable.

[0066] Hook 620 may be formed on the load path unit 400 at a position corresponding to hook support member 610. More preferably, hook 620 may be configured such that one end is fixed to the load path unit 400 while the other end rotates. Hook 620 may be formed as a pair to fix the two ends of hook support member 610. As an embodiment of the present disclosure, when load path connecting member 510 and load path unit 400 are engaged, hook 620 is interference-fitted to hook support member 610. When load path connecting member 510 is fully inserted between load path units 400, hook support member 610 is inserted such that hook 620 is spaced apart. After assembling compartment unit 500, floor covering may be formed on the upper surface of intermediate connecting member 300, the upper surface of load path unit 400, and load path connecting member 510.

[0067] The hook insertion slot 630 is positioned in the load path coupling member 510 and can be configured such that the hook 620 is inserted, thereby securing the load path coupling member 510. More preferably, when the hooks 620 are spaced apart by the insertion hook support member 610, the hook insertion slot 630 limits the amount of rotation of the hooks 620. The hook insertion slot 630 can be formed in each spaced load path coupling member 510 in a shape corresponding to the hook 620. When the load path coupling member 510 is fully inserted between the load path units 400, the hook insertion slot 630 is formed in the longitudinal direction at a position corresponding to the hook 620.

[0068] Figure 6B This is a view showing the hook support member 610 of the closed modular frame structure of a vehicle according to an exemplary embodiment of the present disclosure being released from the hook 620; and Figure 6C This is a cross-sectional view of the fixing unit 600 in the case where the load path coupling component 510 of the vehicle's vehicle enclosure module frame structure is released from the load path unit 400, according to an exemplary embodiment of the present disclosure.

[0069] Reference Figure 6B and Figure 6C When the load path engaging member 510 is released from the load path unit 400, the hook support member 610 is released from the hook 620. More preferably, when the hook support member 610 is released from the hook 620, the hook 620 returns to its original position and is released from the hook insertion slot 630. When the hook 620 is released from the hook insertion slot 630, the load path engaging member 510 is released from the load path unit 400.

[0070] As an embodiment of this disclosure, when the hook support member 610 is released, the hook 620 returns to its original position, allowing the load path coupling member 510 to be released without interference from the load path unit 400. One end of the hook 620 can be hinged to the load path unit 400 via an elastic member. When the hook support member 610 and the hook 620 are in an interference fit, the hook support member 610 is fixed by an elastic repulsive force. When the hook support member 610 is released from the hook 620, the hook 620 can return to its original state by an elastic restoring force.

[0071] The compartment unit 500 can be stably assembled to the vehicle via the guide rail 110, the compartment guide member 521, and the fixing unit 600. More preferably, the side surfaces of the compartment unit 500 can be fixed via the guide rail 110 and the compartment guide member 521, and the middle component of the compartment unit 500 can be fixed via the fixing unit 600. When the compartment unit 500 needs to be replaced, the mounting bolts 700 are released and the hook support member 610 is removed. When the mounting bolts 700 and the hook support member 610 are released, the compartment unit 500 is released in the opposite direction to the direction in which it is inserted into the load path unit 400.

[0072] In summary, the present invention provides a closed modular frame structure for a vehicle, wherein the frame structure allows the cabin unit 500 to be detachably attached to the frame, thereby enabling the assembly of various door components 800 into the PBV vehicle, and includes a load path structure configured to disperse collision energy.
