Description

Technical Field

[0001] The present disclosure relates to a mobile frame for a vehicle, which is configured to be installed inside or outside the vehicle and equipped with various convenience devices that can be freely used by a user inside or outside the vehicle. Background Art

[0002] Autonomous vehicles have evolved from simple transportation means to a concept where the interior space of the vehicle can be utilized while the vehicle is in motion.

[0003] Since the driver does not drive the autonomous vehicle, passengers inside the vehicle can engage in various activities. For this purpose, various convenience devices need to be installed in the vehicle.

[0004] For example, a large-screen display can be installed in the vehicle so that passengers can watch movies, make video calls, or retrieve various information while riding.

[0005] Optionally, storage boxes, tables, etc. can be installed, and an air conditioning device or various mechanisms required in the vehicle may also need to be installed.

[0006] However, in current vehicles, the predetermined mechanisms are installed at predetermined points in a narrow space, making it difficult to meet the various needs of users.

[0007] Therefore, in order for autonomous vehicles to meet the various requirements of users, it is necessary to replaceably install or separate various convenience devices at specific points inside the vehicle to meet the requirements of users.

[0008] On the other hand, vehicles have expanded beyond simple transportation means to a concept of a space that can be used in daily life. After the vehicle stops, the vehicle can be used as a movable store or hotel. In this case, the convenience devices in the vehicle can be used outside the vehicle.

[0009] Therefore, in the future, a system is needed that can be freely installed inside or outside the vehicle and provides a wide range of usage and satisfaction to users through compatibility with the installation of various convenience devices.

[0010] The information included in this background art of the present disclosure is only for enhancing the understanding of the general background art of the present disclosure and cannot be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

[0043] A mobile frame for a vehicle according to an exemplary embodiment of the present disclosure includes: a main body configured such that convenience devices can be mounted on or released from the main body, the main body being coupled to a track formed on the floor of the vehicle, configured to be slidable on the track, and configured to be withdrawn to the outside of the vehicle through a door opening of the vehicle; and mobile wheels connected to a lower portion of the main body through a link assembly, and configured to be accommodated in the lower portion of the main body when the main body is coupled to the floor of the vehicle and to be deployed downward from the main body when the main body is withdrawn to the outside of the vehicle.

[0044] First, an example in which the mobile frame for a vehicle of the present disclosure is applied will be described with reference to the drawings. Figure 1 is a view exemplarily showing a state in which a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is disposed in a vehicle. Figure 2It is a view exemplarily showing a state in which a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is provided outside the vehicle.

[0045] Figure 1 It shows that the mobile frame is provided inside the vehicle. In this example, as shown in the figure, the main body 100 of the mobile frame can be provided on the floor 300 of the vehicle. In addition, a display 520 can be provided on the main body 100 as a convenience device so that passengers can watch the video of the display 520. The main body 100 can be provided on the track 310 of the floor 300 of the vehicle and slide left and right. In the illustrated case, the door 340 is provided on the lateral side of the vehicle body, and the track 310 provided on the floor 300 extends in the left - right width direction of the vehicle. Therefore, the main body 100 of the mobile frame can slide left and right on the floor 300 of the vehicle, that is, slide in the width direction of the vehicle.

[0046] In addition, when the vehicle is stationary and the door 340 is open, the mobile frame can slide through the opening of the door 340 and withdraw to the outside of the vehicle.

[0047] Figure 2 It shows that the mobile frame is withdrawn to the outside of the vehicle. When the main body 100 is withdrawn to the outside of the vehicle, the main body 100 is used to install various convenience devices outside the vehicle. For example, as shown in the figure, a table 560 can be provided on the main body 100 outdoors so that users can enjoy coffee, etc., and various shelves 540 can be provided on the main body 100 so that a simple store can be operated outdoors.

[0048] As described above, the mobile frame of the present disclosure can be fixed in the vehicle and provided outside the vehicle. Various convenience devices can be provided on the mobile frame so that the mobile frame is constructed as a frame with maximum utilization.

[0049] In addition, when the vehicle is an autonomous vehicle or an electric vehicle, the mobile frame of the present disclosure enables the vehicle to be used as a mobile café or store, and the use by users can also be diversified, thus enriching human life.

[0050] Multiple functions are required to enable the mobile frame of the present disclosure to be used both inside and outside the vehicle. Rigidity needs to be ensured in the vehicle to prevent injuries caused by the provided convenience devices in the event of a vehicle collision. Therefore, the main body 100 needs to be made of a material such as steel to ensure rigidity. In addition, the size of the frame needs to fill the interior of the vehicle to ensure the size for installing various convenience devices. In addition, due to the increase in weight caused by the material and size, a track 310 needs to be provided in the vehicle to move the frame, and the frame needs to slide along the track 310.

[0051] To this end, the rail 310 is formed on the floor 300 of the vehicle. The rail 310 extends in the width direction of the vehicle and guides the sliding movement of the main body 100 in the width direction of the vehicle. In addition, the rail 310 extends toward the opening of the vehicle door 340. Accordingly, when the vehicle door 340 is opened, the main body 100 is guided such that the main body 100 slides along the rail 310 to the outside of the vehicle.

[0052] The moving wheels 150 are connected to the lower portion of the main body 100 through a link assembly 140. When the main body 100 is coupled to the floor 300 of the vehicle, the moving wheels 150 are received in the lower portion of the main body 100 and guide the sliding movement of the main body 100 on the rail 310. Since it is difficult for the main body 100 to move due to friction in a state where the main body 100 is in surface contact with the rail 310, the main body 100 can be easily slid by the moving wheels 150 provided in the lower portion of the main body 100, so that the position of the main body 100 can be changed. In addition, when the main body 100 is withdrawn to the outside of the vehicle, the moving wheels 150 are deployed downward from the main body 100 so that the main body 100 remains horizontal during the withdrawal process.

[0053] There is a height difference between the floor 300 of the vehicle and the ground GL. Accordingly, when the main body 100 is withdrawn to the outside of the vehicle, the portion of the main body 100 exposed to the outside needs to be supported on the ground GL. That is, in order to stably withdraw the main body 100, the exposed portion of the main body 100 can be supported on the ground GL, and the remaining unexposed portion of the main body 100 can be supported on the floor 300 of the vehicle, so that the main body 100 can be kept horizontal and the frame can be stably withdrawn without an accident. To this end, the moving wheels 150 are provided on the main body 100 through a link assembly 140. The link assembly 140 is folded and received in the lower portion of the main body 100, and the link assembly 140 is opened and deployed toward the ground GL.

[0054] Figure 3 and Figure 4 is a view exemplarily showing a state in which a link assembly of a moving frame for a vehicle according to an exemplary embodiment of the present disclosure is received, Figure 5 is a view exemplarily showing a state in which a link assembly of a moving frame for a vehicle according to an exemplary embodiment of the present disclosure is deployed.

[0055] As shown in the figure, the main body 100 may have a quadrilateral frame shape. In addition, the convenience devices provided on the main body 100 may be at least one of a display, a storage box, a shelf, and a table.

[0056] On the other hand, a connector 160 is provided at the lower end of the main body 100, and the convenience device can be electrically connected to the vehicle through the connector 160 and the rail 310. The connector 160 can be electrically connected to the convenience device provided on the main body 100. In addition, when the connector 160 can be electrically connected to a separate terminal provided on the rail 310, the connector 160 is connected to the battery of the vehicle through this terminal. Therefore, the convenience device provided on the main body 100 can be electrically connected to the vehicle and data communication can also be achieved.

[0057] On the other hand, the main body 100 can be supported on the rail 310 by the moving wheels 150. In addition, the rail 310 can extend in the direction from the floor 300 of the vehicle toward the door 340.

[0058] The rail 310 may include a groove 301 recessed in the floor 300 of the vehicle, and an engaging portion 320 may be formed on the upper portion of the rail 310. A protruding portion 120 may be formed at the lower end of the main body 100, and in a state where the protruding portion 120 is inserted into the groove 301 of the rail, the protruding portion 120 may be engaged by the engaging portion 320 and not withdrawn upward. Therefore, the main body 100 can slide stably on the rail 310 by the rolling movement of the moving wheels 150. When the engaging portion 320 and the protruding portion 120 are engaged with each other, the main body 100 can be prevented from shaking in the vehicle and withdrawing from the floor 300. Therefore, even when the vehicle collides or the vehicle travels on an uneven road surface, the position of the main body 100 can be stably maintained, thus ensuring the safety and convenience of the passengers.

[0059] When the main body 100 is coupled to the floor 300 of the vehicle, the link assembly 140 can be folded and accommodated in the lower portion of the main body 100, and the lower end of the moving wheel 150 can be exposed downward from the main body 100 and supported on the rail 310.

[0060] Figure 6 is a view exemplarily showing a state in which a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is provided on the floor of the vehicle, Figure 7 is a view exemplarily showing a state in which a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is withdrawn from the vehicle, Figure 8 is a view exemplarily showing a state in which the link assembly of a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is deployed outside the vehicle, Figure 9 is a view exemplarily showing a state in which the link assembly of a mobile frame for a vehicle according to an exemplary embodiment of the present disclosure is accommodated outside the vehicle.

[0061] The link assembly 140 includes a deployment portion configured to provide elasticity in its deployment direction. When the main body 100 is withdrawn to the outside of the vehicle, the link assembly 140 can be deployed through the deployment portion so that the moving wheels can be supported on the ground outside the vehicle. As shown in the figure, an example of the deployment portion may include a cylinder 170 and a piston 174. In addition, the cylinder 170 is filled with hydraulic or pneumatic pressure, and a component such as a spring is embedded in the cylinder 170 so that pressure can always be applied in the direction in which the piston 174 extends.

[0062] Figure 4 is a view exemplarily showing the lower surface of the main body. The moving wheels 150 and the link assembly 140 may be accommodated in the lower part of the main body 100. Figure 4 It shows the link assembly 140 folded and the piston 174 compressed inside the cylinder 170. The cylinder 170 is provided on the main body 100 through a rotating shaft 172, and the link 142 configured to support the moving wheel 150 is also connected to the main body 100 through a rotating shaft 143. In addition, the piston 174 is connected to the link 142 through a support rod 144, so that when the piston 174 retracts, the moving wheel 150 approaches the lower surface of the main body 100, and when the piston 174 extends, the moving wheel 150 is deployed in a direction away from the main body 100.

[0063] Figure 6 It shows the main body disposed on the track of the vehicle floor. In this example, the link assembly 140 is accommodated, and the main body 100 slides on the track 310 through the moving wheels 150 and is connected to the floor 300.

[0064] Figure 7 It shows the vehicle door 340 open, and a part of the main body 100 is withdrawn to the outside of the vehicle through the opening. The link assembly 140 and the moving wheels 150 are disposed on two opposite sides of the lower end of the main body. When the main body 100 is withdrawn from the vehicle, one of the link assemblies 140 on the two opposite sides that is first withdrawn can be deployed and supported on the ground GL through the moving wheel 150', and in this instant state, the remaining part of the main body 100 can be withdrawn. With this configuration, even when a part of the main body 100 is in a withdrawn state, the main body 100 can be stably kept horizontal relative to the ground GL or the vehicle floor 300, thereby preventing damage to the main body 100 and the convenience devices provided on the main body 100. In addition, the main body 100 is stably supported, so that the user withdrawing the main body 100 can conveniently withdraw the main body 100 to the outside without being injured.

[0065] As Figure 8As shown, when the main body 100 is stably withdrawn to the outside of the vehicle, both of the link assemblies 140 are deployed. Thus, in a state where the main body 100 and the ground GL have a predetermined height, the main body 100 can move on the ground GL by the moving wheels 150.

[0066] In addition, in a case where it is necessary to place the main body 100 at a point on the ground GL, both of the link assemblies 140 on two opposite sides contract, so that the main body 100 can be fixed to the ground GL, as Figure 9 shown. Even in this example, a part of the lower end portion of the moving wheels 150 is exposed to the ground, so that the main body 100 can slide on the ground GL. The center of gravity of the main body 100 is lowered by the contraction of the link assemblies 140, so that the main body 100 can be stably used outside the vehicle, as Figure 2 shown.

[0067] The mobile frame for a vehicle of the present disclosure can be provided inside or outside the vehicle and is provided with various convenience devices that can be freely used by a user inside or outside the vehicle.
