[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Sliding doors are a common door structure in modern car design, especially widely used in vans, trucks and some large MPV models. Compared with traditional hinged doors, sliding doors use rails to achieve horizontal sliding of the door, reducing the lateral space required when opening, which makes the vehicle more convenient in narrow parking lots or city streets. However, although sliding doors have shown significant advantages in certain specific scenarios, their structural design and form still have some limitations.

[0004] Traditional sliding doors usually adopt a track design, and the doors slide in a single direction. This type of door structure is mostly composed of three slide rails arranged at the top, middle and bottom of the door, and the track is parallel to the body. Although this design simplifies the operation in horizontal opening and closing, the sliding direction and mode are relatively single. The height between the chassis and the ground of vans, trucks and some large MPV models is relatively high. After the sliding door is opened, it is inconvenient for passengers to get on and off the vehicle, especially for passengers with limited leg and foot mobility. It is more difficult to get on and off the vehicle, which affects the passengers' experience of getting on and off the vehicle. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a three-opening sliding door structure and a vehicle, which improves the experience of passengers getting on and off the vehicle.

[0031] Example 1

[0032] This embodiment provides a three-opening sliding door structure, such as Figure 1 As shown, it includes two relatively arranged horizontal sliding doors, namely a left horizontal sliding door 1 and a right horizontal sliding door 2. The two relatively arranged horizontal sliding doors can move towards or away from each other, thereby realizing the switching between the open and closed states.

[0033] The two horizontal sliding doors are slidably connected to at least two slide rails, and the slide rails are used to guide the sliding of the horizontal sliding doors. The left horizontal sliding door 1 and the right horizontal sliding door 2 cooperate with the slide rails in exactly the same manner.

[0034] One of the slide rails is slidably connected to the bottom edges of the two horizontal sliding doors. The slide rail serves as a movable slide rail 3. The movable slide rail 3 is arranged on a flip door 4 below the two horizontal sliding doors. The flip door 4 can flip toward the outside of the vehicle. When the two horizontal sliding doors are opened, the flip door 4 can flip toward the outside. After the top of the flip door cooperates with the ground, it can serve as a support plate to assist passengers in getting on and off the vehicle.

[0035] The remaining slide rails are used to be fixed on the frame of the automobile and are fixedly arranged to serve as fixed guide rails.

[0036] In this embodiment, each horizontal sliding door is slidably connected to three sliding rails, wherein the sliding rail connected to the bottom edge of the horizontal sliding door is a movable sliding rail, and the other two sliding rails are fixed sliding rails, wherein one of the fixed sliding rails is slidably connected to the set position of the top edge of the horizontal sliding door, and is the upper fixed sliding rail 5, and the other fixed sliding rail is slidably connected to the set position of the outer edge of the horizontal sliding door, and is the middle fixed sliding rail 6.

[0037] Specifically, the setting position of the top edge of the horizontal sliding door is the inner end, and a connecting piece 7 is provided at the inner end, and the connecting piece 7 is slidably connected to the upper fixed slide rail 5. The setting position of the outer edge of the horizontal sliding door is the corner position, that is, the middle position, and a connecting piece 7 is provided at the setting position, and the connecting piece 7 is slidably connected to the middle fixed slide rail 6.

[0038] A connecting piece 7 is provided at the inner end of the bottom edge of the horizontal sliding door, and the connecting piece 7 is slidably connected to the movable slide rail 3 .

[0039] In this embodiment, the fixed slide rail and the movable slide rail corresponding to the horizontal sliding door have the same distribution track and both have an L-shaped slide groove, so that the horizontal sliding door can move along an L-shaped track line.

[0040] like Figure 2As shown, the L-shaped slide groove includes a first slide groove portion 8, and the first slide groove portion 8 is arranged along the opening and closing direction of the two horizontal sliding doors. The inner end of the first slide groove portion 8 is vertically connected to the second slide groove portion 9, and the outer end of the first slide groove portion 8 serves as an expansion end. When the two horizontal sliding doors are in an open state, the connecting member 7 contacts and cooperates with the expansion end, and the second slide groove portion 9 extends toward the inner side of the vehicle. One end of the second slide groove portion 9 is connected to the first slide groove portion 8, and the other end serves as a closed end. When the two horizontal sliding doors are in a closed state, the connecting member 7 contacts and cooperates with the closed end.

[0041] Furthermore, the connecting member 7 adopts a connecting rod, one end of which is fixed to the inner side of the horizontal sliding door, and the other end is provided with a sliding block, which is embedded in the L-shaped sliding groove, and the sliding block is slidably connected to the L-shaped sliding groove.

[0042] In this embodiment, the length of the connecting rod is not less than the length of the second slide groove portion 9 , so that the slider can move to contact the closed end of the second slide groove portion 9 .

[0043] Furthermore, the fixed slide rail includes a slide rail body 10, and the slide rail body 10 also adopts an L-shaped structure, and its shape matches the L-shaped slide groove. The slide rail body is provided with an L-shaped slide groove.

[0044] Furthermore, the L-shaped slide groove of the movable slide rail is provided on the upper surface of the flip door, specifically:

[0045] like Figure 3-Figure 4 As shown, the flip door 4 includes a flip part 4-1, and fixed parts 4-2 are provided on both sides of the flip part 4-1. The fixed parts 4-2 are used to be fixed on the frame to achieve a fixed setting. The flip part 4-1 is rotatably connected to the fixed parts 4-2 to achieve opening and closing of the flip door.

[0046] An L-shaped groove 4-3 is provided on the upper surface of the flipping part 4-1, and a straight groove 4-4 is provided on the upper surface of the fixing part 4-2. The L-shaped groove 4-3 and the straight groove 4-4 together constitute a movable slide rail. Since the two horizontal sliding doors are both equipped with movable slide rails 4, two L-shaped grooves 4-3 are provided on the upper surface of the flipping part 4-1, and straight grooves 4-4 are provided on the upper surfaces of the two fixing parts 4-2.

[0047] The L-shaped groove 4-3 includes a first groove portion distributed along the opening and closing direction of the two horizontal sliding doors, and a second groove portion is vertically provided at the inner end of the first groove portion. The first groove portion can cooperate with the straight groove on the upper surface of the fixed portion on the same side when the flip portion is closed, thereby forming an L-shaped slide groove of the movable slide rail of the horizontal sliding door.

[0048] Furthermore, a rotating shaft 4-5 is provided at the bottom end of the fixed part 4-2, and the bottom of the side end of the flipping part 4-1 is rotatably connected to the fixed part 4-2 through the rotating shaft 4-5. In this way, the flip door does not occupy the space inside the vehicle when installed, and the flip part does not occupy the space inside the vehicle during the flipping process. The entire flipping part 4-1 can be used as a supporting component when passengers get on and off the vehicle, thereby improving the convenience and experience of passengers getting on and off the vehicle.

[0049] The cooperation modes of the two horizontal sliding doors with the fixed slide rail and the movable slide rail 3 are exactly the same, and will not be repeated here.

[0050] The working principle of the three-open sliding door structure of this embodiment is:

[0051] In the closed state, the two horizontal sliding doors are closed, and the flip door 4 is closed. At this time, the slider is at the closed end of the second slide groove portion 9 of the L-shaped slide groove of the slide rail.

[0052] When you need to open the door, Figure 5 As shown, the two horizontal sliding doors move along the second slide groove portion 9 of the L-shaped slide groove through the connecting member 7, and the two horizontal sliding doors leave space for horizontal movement toward the outside of the vehicle. After the slider of the connecting member 7 moves to the corner position of the L-shaped slide groove, the two horizontal sliding doors move away from each other. When the slider at the bottom edge of the horizontal sliding door leaves the first groove portion on the upper surface of the flip portion 4-1, the two horizontal sliding doors are in an open state. At this time, the flip portion 4-1 flips toward the outside of the car, realizing the opening of the flip door 4. At this time, the flip portion 4-1 can be used as a supporting component for passengers to get on and off the vehicle after cooperating with the ground.

[0053] When you need to close the door, Figure 6 As shown, firstly rotate the flip part 4-1 to retract and close the flip door 4, and then the two horizontal sliding doors move toward each other through the first slide groove part 8 of the L-shaped slide groove. When the slider of the connecting member 7 moves to the corner of the L-shaped slide groove, the two horizontal sliding doors move along the second slide groove part 9 toward the inner side of the vehicle until the two horizontal sliding doors cooperate with the frame. At this time, the door is closed.

[0054] The three-opening sliding door structure of the present embodiment has a structure in which when the two horizontal sliding doors are opened until the bottom ends of the horizontal sliding doors are separated from the movable sliding rail portion, the flip portion 4-1 can flip over and open toward the outside of the vehicle. When the flip portion 4-1 contacts the ground, it acts as a connecting plate connected between the bottom surface of the interior space of the vehicle and the external ground. Passengers can get on and off the vehicle through the opened flip doors, which improves the convenience and experience of getting on and off the vehicle for passengers. It is especially suitable for passengers with mobility impairments to get on and off the vehicle. Moreover, the bottom end of the flip portion is rotatably connected to the bottom end of the fixed portion through a rotating shaft. The flip door does not occupy the interior space of the vehicle during flipping, and does not occupy the interior space of the vehicle when the flip door is closed. There is no need to set up additional devices in the interior space of the vehicle to assist passengers in getting on and off the vehicle, which improves the riding experience of passengers.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
