Description

Technical Field

[0001] This invention relates to a vehicle door opening structure. Background Technology

[0002] There are many types of car doors. Among the types of car doors, 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 recreational vehicles (RVs) are examples.

[0003] On the other hand, private vehicle (PBV) mobility is emerging as a future mode of transportation that expands living space. For example, when PBVs serving as shoe stores and clothing stores are parked at a hub, the hub transforms into a shopping mall. The functionality and design of a PBV are highly scalable depending on its purpose. PBVs are a new mode of transportation; they are not private cars or buses, but rather flexible spaces where the purpose of a hub changes depending on the use of the PBVs parked at it.

[0004] To make more effective use of PBV, a door opening structure that can be diversified according to the surrounding environment is needed, as well as an exit door opening structure suitable for the occasion.

[0005] Additionally, in the case of conventional doors equipped with door ramps, the ramp storage space, which is configured separately from the door, requires a separate space in the underfloor for the ramp to be inserted.

[0044] Furthermore, in the embodiments of this disclosure, the first door 110 of the first door unit 100 is located at the upper end relative to the second door 210 of the second door unit 200, and the second door 210 is disposed at a position adjacent to the bottom surface of the vehicle body 600. In the embodiments, the first door unit 100 and the second door unit 200 located on one side of the vehicle will be described below.

[0045] Figure 1A This is a front view showing the first gate unit 100 and the second gate unit 200 according to an embodiment of the present disclosure, and Figure 1B This is a rear view showing a first gate unit 100 and a second gate unit 200 according to an embodiment of the present disclosure.

[0046] As shown in the figure, the first door unit 100 is configured to include a first door 110 and is configured to be located at least a portion of the upper part of the side of the vehicle to cover at least a portion of the open portion of the vehicle, and the second door unit 200 is configured to be located at the lower end of the first door 110. The second door unit 200 includes a second door 210 located at the lower part of the first door 110 so as to be configured to cover the remaining open surface of the open portion of the vehicle.

[0047] The first door unit 100 may be configured to include: a drive unit 400, which is fastened to the first door 110 and applies a driving force in the sliding direction of the first door 110; and a fixing part 420, wherein the drive unit 400 and the first door 110 are fastened to the fixing part 420.

[0048] In embodiments of this disclosure, the drive unit 400 may be a main shaft 410 configured such that its first end is located in the first door 110 and its second end is fixed to the first end inside the vehicle. The first end of the main shaft 410 fixed to the fixing portion 420 includes a retaining protrusion 430, such that the first door 110 is configured to move together with the main shaft 410 in the same direction of movement while being fixed to the fixing portion 420.

[0049] The first door 110 is configured to be slidably inserted into the space between the vehicle body 600 and the vehicle interior material 800 by moving along the side of the vehicle adjacent to the first door 110 via a drive unit 400, thereby opening the first door 110. In an embodiment, a two-way opening structure is included. More preferably, the first door 110 is configured such that at least a portion of the first door 110 is located in the space between the vehicle body 600 and the vehicle interior material 800 when the first door 110 is in an open state and a closed state.

[0050] The second door unit 200 includes a second door 210, which is positioned adjacent to the lower surface of the first door 110. The side of the second door 210 can be positioned adjacent to the space between the vehicle body 600 and the vehicle interior material 800, and the second door 210 can be configured to slide open in the same direction of movement as the first door 110 when the second door 210 is opened together with the first door 110. Furthermore, when the fixation between the first door unit 100 and the second door unit 200 is released, the second door 210 can be independently rotated open relative to the lower first end of the vehicle body 600.

[0051] That is, in the closed state, the second door 210 can be separated from the body 600 located on both sides of the second door 210, so that the second door 210 can move independently in such a way that the upper end of the second door 210 rotates open relative to the lower part of the body 600.

[0052] The second door 210 rotates open in response to the vehicle's opening conditions or a user's request, thereby providing an inclined surface at a predetermined angle to the vehicle's floor 700. In embodiments of this disclosure, the second door 210 can perform a ramp function when opened independently.

[0053] The first door unit 100 and the second door unit 200 can be moved together by being engaged with the locked unit 300, and the first door unit 100 and the second door unit 200 are configured to perform independent actions when the engagement of the locked unit 300 is released.

[0054] The first door 110 is configured to be fastened to a drive unit 400, which extends from the vehicle body 600 and applies driving force to the first door 110. In embodiments of this disclosure, the drive unit 400 may be a main shaft 410 positioned in the direction of movement of the first door 110. More preferably, the drive unit 400 may be configured to be fastened to the first door unit 100 via a fixing portion 420 located on the rear surface of the first door 110. The fixing portion 420 may be configured as a clamp, and in embodiments of this disclosure, a first end of the main shaft 410 may be configured to be fastened to and located in the clamp.

[0055] The control unit 500 can control the driving force of the drive unit 400 located in the first door unit 100, and the control unit 500 can also control the drive of the locking unit 300 located between the first door unit 100 and the second door unit 200.

[0056] The second door unit 200 includes a second door 210, a guide portion 220, and a rotating portion 230. The second door 210 extends and is located at the lower end of the first door 110. The guide portion 220 is fastened to the second door 210 and configured to have a shape that corresponds in a direction substantially to the direction of movement of the drive unit 400 between the vehicle body 600 and the vehicle interior material 800. The rotating portion 230 is configured to contact the second door 210 and to perform independent rotational opening of the second door 210 when the fixation between the first door 110 and the second door 210 is released.

[0057] When the locking unit 300 releases the fixation between the first door 110 and the second door 210, the control unit 500 responds to the user's request to drive the rotating part 230, so that the second door 210 is configured to rotate and open independently of the first door unit 100 based on the guide part 220.

[0058] The second door 210, configured to open by rotating, is arranged such that its upper end contacts the ground, thereby providing passengers with a predetermined sloping area from the ground to the floor 700 inside the vehicle. That is, the independently opening second door 210 is configured to perform a ramp function along the floor surface of the vehicle body 600.

[0059] Figure 1C It is along Figure 1B The cross-sectional view of line AA, and Figure 1D It is along Figure 1B The cross-sectional view of line BB.

[0060] like Figure 1C As shown, in the fully closed state, the lower end of the second door 210 is configured to cover at least a portion of the guide portion 220, such that the second door 210 is positioned together with the first door 110 at the open surface of the vehicle. The guide portion 220 is located between the outermost surface of the body 600 and the vehicle interior material 800, and extends in the direction in which the second door 210 is slidably opened. More preferably, the guide portion 220 is configured to have a length at least longer than the length of the second door 210 that is slidably opened. Furthermore, the guide portion 220 is configured to extend in a direction corresponding to the direction of movement of the drive unit 400 fastened to the first door 110.

[0061] In summary, when the second door 210 moves together with the first door 110 via the locking unit 300, the second door 210 is configured to extend along the longitudinal direction of the guide portion 220, which is located in the lower surface of the second door 210 and configured to be covered by at least a portion of the second door 210. That is, the guide portion 220 is configured to extend in a direction corresponding to the slidable opening direction of the first door unit 100 and is located at the lower end of the second door 210 to guide the second door 210 in the slidable opening direction. The guide portion 220 may be configured to be located at the end of the vehicle body 600 frame and configured to guide the second door 210, which moves together with the first door 110, to move along the longitudinal direction of the guide portion 220, and is configured to operate as a central axis around which the second door 210 rotates and opens independently of the first door 110.

[0062] Figure 2 This shows the first end of the drive unit 400 located in the first gate unit 100 according to an embodiment of the present disclosure.

[0063] The first door 110 is configured such that it is secured to the drive unit 400 on a first surface facing the vehicle interior, and is configured to move in response to longitudinal movement of the drive unit 400. A first end of the drive unit 400 is configured to be secured to the first door 110 by means of a fixing portion 420 located in the first door 110, such that a retaining protrusion 430 located in the first end of the drive unit 400 is fixed to the fixing portion 420. The fixing portion 420 may be configured as a clamp, such that the fixing portion 420 of the drive unit 400 is configured to fix the first end of the main shaft 410. Therefore, the first door unit 100 is configured such that the first door 110 switches to an open or closed state in response to longitudinal movement of the drive unit 400.

[0064] Furthermore, the second door 210, which is fastened to the first door unit 100 by the locking unit 300, can be switched to an open or closed state together with the first door unit 100 by the driving force of the driving unit 400.

[0065] Figure 3A This is a view showing the state in which the second door unit 200 and the first door unit 100 are opened together when the locking unit 300 is fastened to the second door unit 200 and the first door unit 100.

[0066] When a driving force is applied from the drive unit 400 while the locking unit 300 is fastened to the first door 110 and the second door 210, the first door 110 and the second door 210 move together along the drive unit 400, thereby switching to a fully open state or a fully closed state.

[0067] Thus, the second door 210 moves into the interior of the vehicle body 600, such that the second door 210 is inserted along the guide portion 220 and located inside the vehicle body 600, as... Figure 3B As shown. For example, guide portion 220 is fixed to the body 600 and located at the lower end of the second door 210. Guide portion 220 is configured to be located between the outer surface of the body 600 and the vehicle interior material 800, such that the second door 210 is configured to slide together with the first door 110.

[0068] That is, the first door 110 and the second door 210 can be configured to open together or independently depending on the fastening state of the locking unit 300.

[0069] Figure 3B This is a cross-sectional side view showing the second door 210 in the open state. (See attached image.) Figure 3B As shown, the second door 210 is positioned along the guide portion 220 near the floor 700. The second door 210 is configured to move to a position facing the vehicle interior material 800 while near the floor 700.

[0070] Figure 4A The view shows a state where the first door 110 is slidably open and the second door 210 is closed with the locking unit 300 released. Figure 4B This view shows the state in which the first door 110 is slidably opened and the second door 210 is rotated open with the locking unit 300 released.

[0071] When the user requests to open the door, a signal to open the first door 110 is applied while the locking unit 300 is released by the control unit 500, and the drive unit 400 applies a driving force to the first door 110, so that the first door 110 is inserted into the space inside the vehicle body 600 on the side of the first door 110.

[0072] Even when the first door 110 is switched to the open state, the second door 210, whose locking unit 300 is released, is configured to move independently of the first door 110. For example... Figure 4A As shown, the second door 210 can remain in the closed state, and can also be configured such that the driving force of the rotating part 230 is applied to the lower end of the second door 210, causing the second door 210 to rotate and open around the guide part 220, as shown. Figure 4B As shown. The second door 210 is configured such that when the second door 210 is rotated open relative to the guide portion 220 located at the lower end of the vehicle body 600 by the rotational force of the rotating portion 230, the second door 210 opens to form a predetermined inclined area with the floor plate 700 inside the vehicle body 600.

[0073] The rotating part 230 may be configured to be positioned adjacent to the guide part 220, and more preferably, at least a portion of the second door 210 may be configured to be located between the rotating part 230 and the guide part 220.
