Description

Technical Field

[0001] The present disclosure relates to a pop-up floor system for a vehicle, which is configured to form the floor of the vehicle in a normal state and pop up when needed to provide a table or a seat, thereby providing convenience for the passengers of the vehicle. Background Art

[0002] Autonomous vehicles are evolving beyond being mere transportation tools to the concept of being able to utilize the interior space of the vehicle during transportation.

[0003] In such autonomous vehicles, the driver does not drive the vehicle, and thus, the passengers in the vehicle can engage in various activities. Therefore, it is necessary to provide various convenience devices inside the vehicle.

[0004] However, in currently developed vehicles, only necessary devices are provided at necessary positions in a limited space, and thus, it is difficult to fully meet the various needs of users.

[0005] Currently, in autonomous vehicles, there is a need for a technology that selectively deploys various convenience devices, such as in a pop-up manner, on the interior floor of the vehicle and selectively enables various convenience devices to be used.

[0006] On the other hand, vehicles are evolving beyond being mere transportation tools and expanding towards the concept of a space that can be used in daily life.

[0007] Therefore, essentially, there is a need for a system that can not only be freely configured inside the vehicle but also bring extensive practicality and satisfaction to users by providing various convenience devices.

[0008] The information included in the background art section of the present disclosure is only for enhancing the understanding of the general background of the present disclosure and should not be construed as an admission or any form of suggestion that such information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0009] Aspects of the present disclosure are directed to providing a pop-up floor system for a vehicle, which is configured to form the floor of the vehicle in a normal state and pop up when needed to provide a table or a seat, thereby providing convenience for the passengers of the vehicle.

[0010] The object of the present disclosure is not limited to the above object, and other objects of the present disclosure that have not been described will be more clearly understood by those skilled in the art from the following detailed description.

[0011] According to one aspect of the present disclosure, the above object and other objects can be achieved by providing a pop-up floor system for a vehicle, the pop-up floor system including: a vehicle floor that is recessed downward to form a storage space; a table that is configured to be stored in the storage space of the floor; a link assembly that is configured to interconnect the table and the storage space, and fold in a state where the table is stored in the storage space and unfold when the table pops up to move away from the storage space; and an actuator that is coupled to the link assembly and is configured to provide an unfolding force to the link assembly.

[0012] The storage space may be formed to include an area that is the same as the area of the table, and in a state where the table is stored in the storage space, the upper surface of the table may form the same plane as the upper surface of the floor.

[0013] The link assemblies may be arranged in pairs such that a pair of link assemblies are respectively provided on opposite sides of the table.

[0014] The actuator may be a gas spring connected between a pair of link assemblies to provide an unfolding force to the link assemblies.

[0015] The gas springs may simultaneously push the link assemblies provided on opposite sides of the table along the extension directions of the gas springs respectively, such that the opposite link assemblies unfold simultaneously.

[0016] The table may be divided into a plurality of table parts, and each of the table parts may rotate relative to its connection point with the link assembly.

[0017] When the table moves away from the storage space in the popped-up state, the table parts may rotate 180° to flip over.

[0018] Each of the table parts may have opposite surfaces respectively defined as a floor surface and a usable surface, and may be pushed by a spring such that the floor surface faces upward.

[0019] When each of the table parts moves away from the storage space in the popped-up state, the table parts may be pulled by a wire such that the usable surfaces of the table parts rotate to face upward.

[0020] A seat backrest may be connected to the upper surface of the table.

[0021] The seat backrest may rotate on the table, and when the seat backrest overlaps with the table in a state where the table is stored in the storage space, the upper surface of the seat backrest may form the same plane as the floor, and the lower surface of the seat backrest may face the table.

[0022] When the table moves away from the storage space in the popped-up state and the seat backrest unfolds from the table, the lower surface of the seat backrest may form a seat surface.

[0023] The pop-up floor system of a vehicle according to an exemplary embodiment of the present disclosure has the following effects. That is, the pop-up floor system can be configured to form the floor of the vehicle in a normal state and pop up when needed to provide a table or a seat, thereby providing convenience for the passengers of the vehicle.

[0041] Figure 1 It shows a vehicle provided with a pop-up floor system of a vehicle according to an exemplary embodiment of the present disclosure, and Figure 11 It shows a pop-up floor system of a vehicle according to another exemplary embodiment of the present disclosure.

[0042] As Figure 1 shown, the floor 100 is provided at the bottom inside the vehicle. In a conventional vehicle, the floor of the vehicle includes a fixed panel structure. However, the floor of the present disclosure is provided with a table 300 which is configured to be deployed in a pop-up manner. The table 300 is stored in the floor 100 in a normal state, but pops up when needed to perform the function of the table. Passengers can dine, have meetings, or read and study on the table 300. Therefore, in a normal state, the user can store the table 300 at the bottom of the vehicle to use the widened floor area, and when needed, the table 300 can be popped up to use the table 300.

[0043] Figure 11 The case of [[ID=]] is the case of providing an additional seat through the pop-up floor system as described above. In this case, in a normal state, the seat is folded so that the seat is stored in the floor 100, and thus, the floor function is performed, and similar to the above case, it pops up when needed to provide an additional seat. In this case, in addition to the existing seats, additional seats can be used in the vehicle, and when the seats are not needed, the seats can be stored in the floor. Therefore, the advantage is that the interior space of the vehicle can be used in a widened state.

[0044] First, an exemplary embodiment of providing a table through a pop-up floor system according to an exemplary embodiment of the present disclosure will be described. Figure 2 and Figure 3Shows the state in which the table of the pop-up floor system according to an exemplary embodiment of the present disclosure is stored. Figure 4 and Figure 5 Shows the state in which the table of the pop-up floor system according to an exemplary embodiment of the present disclosure is deployed.

[0045] The pop-up floor system according to an exemplary embodiment of the present disclosure includes: a floor 100, the floor 100 being recessed downward to form a storage space 120; a table 300, the table 300 being configured to be stored in the storage space 120 of the floor 100; a link assembly 500, the link assembly 500 being configured to interconnect the table 300 and the storage space 120, and being folded in a state where the table 300 is stored in the storage space 120 and being deployed when the table 300 pops up to move away from the storage space 120; and an actuator, the actuator being configured to provide a deployment force to the link assembly 500.

[0046] A predetermined portion of the floor 100 is recessed downward to form the storage space 120. When the table 300 is stored in the storage space 120 in a normal state, there is a boundary between the table 300 and the floor 100. However, the floor 100 generally remains in a flat state. When the table 300 needs to be used, the table 300 extends upward from the storage space 120 to be deployed, and thus, can be moved away from the storage space 120. Therefore, the pop-up of the table 300 is achieved. For the pop-up, the table 300 is connected to the storage space 120 through the link assembly 500, and the link assembly 500 is deployed by the actuator.

[0047] Therefore, in a normal state, the link assembly 500 is folded, storing the table 300 in the storage space 120, and thus, the table 300 forms the floor 100. When needed, the link assembly 500 is deployed by the operation of the actuator (seat back 340), and thus, the table 300 pops up from the storage space 120.

[0048] Figure 2 and Figure 3 Shows the state in which the table of the pop-up floor system according to an exemplary embodiment of the present disclosure is stored. In this state, through the folding of the link assembly 500, both the link assembly 500 and the table 300 are stored in the storage space 120 of the floor 100. On the other hand, Figure 4 and Figure 5 Shows the state in which the table 300 of the pop-up floor system according to an exemplary embodiment of the present disclosure is deployed. In this state, the table 300 pops up through the deployment of the link assembly 500.

[0049] Since the table 300 should be stored in the storage space 120 in the normal state to form the complete structure of the floor 100, the storage space 120 is formed to include the same area as the table 300. Therefore, in the state where the table 300 is stored in the storage space 120, the upper surface of the table 300 can form the same plane as the upper surface of the floor 100. Thus, in the normal state, the floor 100 including the widened area can be used to the maximum extent.

[0050] On the other hand, the link assemblies 500 can be arranged in pairs such that a pair of link assemblies 500 are respectively provided on opposite sides of the table 300. In addition, the table 300 can be divided into a plurality of table portions 310, and each table portion 310 can rotate relative to the connection point of the table portion and the corresponding one of the link assemblies 500.

[0051] Specifically, the table 300 includes a pair of table portions 310 that are laterally separated from each other. Each separated table portion 310 can be configured to rotate independently. Since each table portion 310 has a planar shape, the opposite surfaces of the table portion 310 are defined as the floor surface 310A and the usable surface 310B. Therefore, when the table 300 is stored, the floor surface 310A faces upward, and when the table 300 is popped up to be used as a table, each table portion 310 rotates 180°, so that the usable surface 310B of each table portion faces upward. Thus, in the normal state, the usable surface 310B can be kept clean.

[0052] When the table portion 310 changes between the stored state and the deployed state, the table portion 310 should rotate simultaneously. For this purpose, as shown in the figure, each link assembly 500 includes two links. First, the upper V-shaped link 540 is hinged to the table portion 310 and the gas spring 700. In addition, the support link 520 provided below the V-shaped link 540 is hinged to the lower portion of the V-shaped link 540. The upper end portion of the support link 520 is connected to the V-shaped link 540, and the lower end portion of the support link 520 is pivotally fixed to the bottom of the storage space 120 by a hinge. Therefore, when the gas spring 700 provided at the center extends, the gas spring 700 pushes the link assemblies 500 provided on the opposite side of the gas spring 700, so that the link assemblies 500 are spaced apart from each other. Thus, the link assemblies 500 are deployed, and accordingly, the table 300 pops up upward. The gas spring 700 includes a cylinder 720 and a piston 740, and the piston 740 is slidably coupled to the cylinder 720.

[0053] That is to say, the actuator can be a gas spring 700, and the gas spring 700 is connected between a pair of link assemblies 500 to provide a deployment force to the link assemblies 500. The gas spring 700 can simultaneously push the link assemblies 500 disposed on opposite sides of the gas spring 700 in the extension direction of the gas spring 700 respectively. Therefore, the opposite link assemblies 500 are deployed simultaneously.

[0054] The gas spring 700 is assembled in a preloaded state such that the gas spring 700 is pushed to extend in a normal state. Therefore, when no external force is applied, the link assemblies 500 are always pushed by the gas spring 700 in the deployment direction of the link assemblies 500. For this purpose, when the table 300 is stored in the storage space 120, the table 300 is locked in the storage space 120 of the floor 100 using a separate lock or the like. When the table 300 is to be ejected, the lock is opened, and thus, the table 300 is automatically ejected by the pressure of the gas spring 700.

[0055] In order to enable the table portion 310 to rotate when ejected, the table portion 310 and the link assemblies 500 are interconnected by a rotation mechanism 320. Each rotation mechanism 320 includes a housing 321 and a stopper. The housing 321 is disposed on one side of a corresponding one of the link assemblies 500, and the stopper is formed inside the housing 321. A rotation shaft 311 is inserted into the housing 321. The rotation shaft 311 is formed at an end of each table portion 310 corresponding to the rotation mechanism 320. A rod 312 extends from the rotation shaft 311. By a 180° rotation of the rod 312, the rod 312 can contact the stopper 322, and thus, the rotation of the rod 312 is restricted. In addition, a spring S is disposed between the rod 312 and the stopper 322 to push the rod 312 such that the rod 312 is always located on one side of the stopper 322. Therefore, the rod 312 is always pushed to be in the Figure 6 state, and thus, the table portion 310 is pushed such that the floor surface 310A of the table portion 310 faces upward.

[0056] When the table portion 310 rotates 180° clockwise from the Figure 6 state, the rotation shaft 311 of the table portion 310 rotates inside the housing 321, as shown in Figure 7 . According to the rotation of the rotation shaft 311, the rod 312 is configured to perform a circular motion and then contact the opposite side of the stopper 322, and thus, the rotation of the rotation shaft 311 stops. At this time, the usable surface 310B of the table 300 faces upward. When the external force is removed in this state, the table portion 310 rotates in the reverse direction again by the restoring force of the spring S, and thus, the rotation mechanism 320 can return to the Figure 6 state.

[0057] On the other hand, in the case where the table 300 should rotate while the table 300 pops up, the usable surface 310B faces upward, and in the case where the table 300 should rotate in the reverse direction while the table 300 moves downward for storage, the usable surface 310B is protected and the floor surface 310A is exposed. That is, when the upward / downward movement and rotation of the table 300 are performed simultaneously, it is convenient for the user. For this function, when the table portion 310 moves away from the storage space 120 in the popped-up state, the table portion 310 is pulled by the wire W and thus rotates so that the usable surface 310B of the table portion 310 faces upward.

[0058] Specifically, as described above, a rod 312 is provided at the rotation axis 311 of the table portion 310, and a control plate 313 is provided outside the rotation axis 311. The control plate 313 is formed with a hole 314. The rod 312 of the table portion 310 is inserted into the hole 314 of the control plate 313. Therefore, when the control plate 313 rotates, the table portion 310 also rotates. To rotate the control plate 313, a reduction gear 315 is connected to the control plate 313, and the wire W is wound around the reduction gear 315. When the wire W is pulled, the reduction gear 315 rotates, causing the control plate 313 to rotate. Therefore, the table portion 310 rotates 180°.

[0059] Figure 8 The state in which the table 300 is stored is shown. When the wire W is pulled in this state, the reduction gear 315 rotates counterclockwise, as Figure 9 shown. Therefore, the control plate 313 also rotates clockwise, and thus, the table portion 310 rotates 180° clockwise.

[0060] As Figure 10 shown, the connection of the wire W is realized. As Figure 10 shown, the opposite end portions of the wire W are respectively connected to the reduction gears 315 provided on the opposite sides. In addition, the wire W is arranged to extend along the link assembly 500 and the gas spring 700. Therefore, when the gas spring 700 extends as the table 300 pops up from the stored state, the opposite end portions of the wire W are pulled to compensate for the extended length of the gas spring 700, thereby rotating the reduction gears 315 provided on the opposite sides.

[0061] By the rotation of the reduction gear 315, the table portion 310 automatically rotates. When the rod 312 contacts the stopper 322, each table portion 310 stops in the state where the table portion 310 has rotated 180°. In this state, by the pressure of the gas spring 700 and the stopper 322, the table 300 is temporarily fixed in the state where the usable surface 310B faces upward.

[0062] When the user presses the table portion 310, as the gas spring 700 is compressed, the table portion 310 moves downward. Accordingly, the spring S rotates the rod 312, and thus, the table portion 310 also rotates. Subsequently, the table portion 310 is stored, and at the same time, the floor surface 310A faces upward. According to the above configuration, according to the storage movement and the pop-up movement of the table 300, the table 300 automatically rotates, and thus, the available surface 310B can be protected from being soiled and the table 300 can be used in a clean state.

[0063] On the other hand, Figure 11 A pop-up floor system for a vehicle according to another exemplary embodiment of the present disclosure is involved. In this case, the seat back 340 may be connected to the upper surface of the table 300. When the table 300 pops up and the seat back 340 is unfolded, the table 300 can be used as a seat cushion.

[0064] Specifically, Figure 12 The state in which the table 300 is stored is shown, and Figure 13 The state in which the table 300 pops up and accordingly becomes a seat is shown. For this function, the seat back 340 can rotate on the table 300. When the seat back 340 overlaps with the table 300 in a state where the table 300 is stored in the storage space 120, the upper surface 340A of the seat back 340 forms the same plane as the floor 100, and the lower surface 340B of the seat back 340 can face the table 300.

[0065] When the table 300 is moved away from the storage space 120 by the pop-up of the table 300 and the seat back 340 is unfolded from the table 300, the lower surface 340B of the seat back 340 can form a seat surface.

[0066] In order to enable the table 300 to be stored in the storage space 120 in a normal state, the storage space 120 should be formed to have a depth corresponding to the total thickness of the table 300 and the seat back 340 in an overlapping state. In addition, the seat back 340 and the table 300 overlap each other such that their seat surfaces face each other, and thus, the seat surface can be protected from being soiled. Similar to the previous embodiment, the pop-up of the table 300 is achieved by the gas spring 700. After the table 300 is fully popped up, the seat back 340 rotates manually or by a motor, and thus, a complete seat is provided together with the table 300.

[0067] After using the seat, fold the seat back 340 so that the seat back 340 overlaps with the table 300, and press down the table 300 to store it in the storage space 120. Accordingly, the floor 100 of the vehicle can be used in an expanded state.

[0068] The pop-up floor system of a vehicle according to an exemplary embodiment of the present disclosure may be configured to form the floor of the vehicle in a normal state and pop up when needed to provide a table or a seat, thereby providing convenience for the passengers of the vehicle.
