Description
Technical Field
[0001] The present invention relates to the technical field of vehicle doors, and particularly to a three-opening sliding door structure and a vehicle. Background Art
[0002] The statements herein only provide background art related to the present invention and do not necessarily constitute prior art.
[0003] Sliding doors are a common door structure in modern vehicle design, especially widely used in van-type vehicles, trucks, and some large MPV models. Compared with traditional hinged doors, sliding doors achieve horizontal sliding of the door through slide rails, reducing the lateral space required for opening, which makes the vehicle more convenient in narrow parking lots or urban streets. However, despite the significant advantages shown by sliding doors in certain specific scenarios, there are still some limitations in their structural design and form.
[0004] Traditional sliding doors usually adopt a track design, and the door slides in a single direction. Such a door structure is mostly composed of three slide rails respectively arranged above, in the middle, and below the door, and the tracks are parallel to the vehicle body. Although this design simplifies the operation in horizontal opening and closing, the sliding direction and mode are relatively single. The distance between the chassis of van-type vehicles, trucks, and some large MPV models and the ground is relatively high, and it is inconvenient for passengers to get on and off the vehicle after the sliding door is opened, especially for passengers with inconvenient leg movement, which affects the boarding and alighting experience of passengers. Summary of the Invention
[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a three-opening sliding door structure and a vehicle, which improve the boarding and alighting experience of passengers.
[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions:
[0007] In a first aspect, an embodiment of the present invention provides a three-opening sliding door structure, including two horizontally sliding doors arranged opposite to each other. Both of the two horizontally sliding doors are slidably connected to at least three slide rails with consistent distribution trajectories. A flip door is provided below the two horizontally sliding doors. The flip door includes a flip part, and both ends of the flip part are provided with fixed parts. The fixed parts are fixedly arranged, and the flip part is rotatably connected to the fixed parts to achieve flipping.
[0008] Optionally, one of the slide rails of the horizontally sliding door is arranged on the top surface of the flip door as a movable slide rail, and the remaining slide rails are fixedly arranged as fixed slide rails. A movable slide rail part is provided on the top surface of the flip part, and a fixed slide rail part is provided on the top surface of the fixed part. The movable slide rail part and the fixed slide rail part constitute the movable slide rail.
[0009] Optionally, one of the fixed slide rails is slidably connected to a set position on the outer edge of the horizontal sliding door, and the top edge of the horizontal sliding door is slidably connected to at least one fixed slide rail.
[0010] Optionally, the L-shaped groove of the movable slide rail is composed of an L-shaped groove opened on the top surface of the flipping part and a linear groove opened on the top surface of the fixed part.
[0011] Optionally, the slide rails connected to the horizontal sliding door are all fixed slide rails. One of the fixed slide rails is slidably connected to a set position on the outer edge of the horizontal sliding door, and the top edge of the horizontal sliding door is slidably connected to at least two fixed slide rails.
[0012] Optionally, the fixed slide rail includes an L-shaped slide rail body. The slide rail body is provided with an L-shaped slide groove matching the shape of the slide rail body. The horizontal sliding door is slidably connected to the slide rail through the L-shaped slide groove.
[0013] Optionally, the L-shaped slide groove includes a first slide groove part and a second slide groove part vertically arranged at the end of the first slide groove part. The second slide groove part extends towards the vehicle interior direction. The horizontal sliding door is provided with a connecting piece, and the connecting piece is slidably connected to the slide rail through the L-shaped groove.
[0014] Optionally, the connecting piece includes a connecting rod. One end of the connecting rod is fixed to the horizontal sliding door, and the other end is provided with a slider. The slider is embedded in the L-shaped slide groove, and the length of the connecting rod is greater than the length of the second slide groove part.
[0015] Optionally, a rotating shaft is provided at the bottom end of the fixed part of the flipping door, and the bottoms of both ends of the flipping part are rotatably connected to the rotating shaft.
[0016] In a second aspect, an embodiment of the present invention provides a vehicle provided with the three-opening sliding door structure described in the first aspect.
[0017] The beneficial effects of the present invention are as follows:
[0018] 1. In the door structure of the present invention, a flipping door is provided below the horizontal sliding door. The flipping door includes a fixed part and a flipping part rotatably connected to the fixed part. The flipping part can flip and thus open towards the outside of the vehicle.

[0034] Embodiment 1
[0035] This embodiment provides a three-opening sliding door structure, as Figure 1 shown, including two horizontally sliding doors arranged oppositely, namely the left horizontal sliding door 1 and the right horizontal sliding door 2. The two horizontally sliding doors arranged oppositely can move towards or away from each other, so as to realize the switching between the open and closed states.
[0036] Both of the two horizontal sliding doors are at least slidably connected to two slide rails. The slide rails are used to guide the sliding of the horizontal sliding doors. The cooperation modes of the left horizontal sliding door 1 and the right horizontal sliding door 2 with the slide rails are exactly the same.
[0037] One of the slide rails is slidably connected to the bottom edges of the two horizontal sliding doors. This slide rail serves as the movable slide rail 3. The movable slide rail 3 is arranged on the flip door 4 below the two horizontal sliding doors. The flip door 4 can make a flipping movement towards the outside of the vehicle. When the two horizontal sliding doors are in the open state, the flip door 4 can flip towards the outside. After the top end 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.
[0038] The remaining slide rails are used to be fixed on the vehicle frame and are fixedly arranged as fixed guide rails.
[0039] In this embodiment, each horizontal sliding door is slidably connected to three slide rails. Among them, the slide rail connected to the bottom edge of the horizontal sliding door is the movable slide rail, and the other two slide rails are fixed slide rails. One of the fixed slide rails is slidably connected to the set position of the top edge of the horizontal sliding door, which is the upper fixed slide rail 5, and the other fixed slide rail is slidably connected to the set position of the outer edge of the horizontal sliding door, which is the middle fixed slide rail 6.
[0040] Specifically, the set position of the top edge of the horizontal sliding door is the inner end portion. A connecting member 7 is provided at the inner end portion. The connecting member 7 is slidably connected to the upper fixed slide rail 5. The set position of the outer edge of the horizontal sliding door is the corner position, that is, the middle position. A connecting member 7 is provided at the set position. The connecting member 7 is slidably connected to the middle fixed slide rail 6.
[0041] A connecting member 7 is provided at the inner end portion of the bottom edge of the horizontal sliding door. The connecting member 7 is slidably connected to the movable slide rail 3.
[0042] 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.
[0043] like Figure 2 As 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.
[0044] 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.
[0045] 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 .
[0046] 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.
[0047] Furthermore, the L-shaped slide groove of the movable slide rail is provided on the upper surface of the flip door, specifically:
[0048] like Figures 3 - 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.
[0049] 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.
[0050] 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.
[0051] Furthermore, a rotating shaft 4-5 is provided at the bottom end of the fixing part 4-2, and the bottom of the side end part of the flipping part 4-1 is rotationally connected to the fixing part 4-2 through the rotating shaft 4-5. In this way, the flipping door does not occupy the space inside the vehicle during installation, and the flipping part does not occupy the space inside the vehicle during the flipping process. The entire flipping part 4-1 can be used as a support component when passengers get on and off the vehicle, improving the convenience and experience of passengers getting on and off the vehicle.
[0052] The cooperation modes of the two horizontal sliding doors with the fixed sliding rail and the movable sliding rail 3 are exactly the same, and will not be repeated here.
[0053] The working principle of the three-opening sliding door structure of this embodiment is as follows:
[0054] In the closed state, the two horizontal sliding doors are closed, and the flipping door 4 is closed. At this time, the slider is at the closed end of the second chute part 9 of the L-shaped chute of the sliding rail.
[0055] When the door needs to be opened, as Figure 5 shown, the two horizontal sliding doors move along the second chute part 9 of the L-shaped chute through the connecting piece 7. The two horizontal sliding doors move towards the outside of the vehicle, leaving space for horizontal movement. After the slider of the connecting piece 7 moves to the corner position of the L-shaped chute, 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 chute part on the upper surface of the flipping part 4-1, the two horizontal sliding doors are in the open state. At this time, the flipping part 4-1 flips towards the outside of the vehicle, realizing the opening of the flipping door 4. At this time, after the flipping part 4-1 cooperates with the ground, it can be used as a support component for passengers to get on and off the vehicle.
[0056] When the door needs to be closed, as Figure 6 shown, first rotate the flipping part 4-1 to retract and close the flipping door 4, and then the two horizontal sliding doors move towards each other through the first chute part 8 of the L-shaped chute. When the slider of the connecting piece 7 moves to the corner of the L-shaped chute, the two horizontal sliding doors then move towards the inside of the vehicle along the second chute part 9 until the two horizontal sliding doors cooperate with the vehicle frame, and at this time, the closing of the door is completed.
[0057] In the three-opening sliding door structure of this embodiment, when the two horizontal sliding doors are opened until the bottom ends of the horizontal sliding doors are separated from the movable slide rail part, the flipping part 4-1 can flip, so as to open towards the outside of the vehicle. When the flipping part 4-1 contacts the ground, it acts as a connecting plate 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 flipping door, which improves the convenience and experience of getting on and off the vehicle, especially suitable for passengers with inconvenient legs and feet. Moreover, the bottom end of the end part of the flipping part is rotationally connected to the bottom end of the fixed part through a rotating shaft. During the flipping process of the flipping door, it does not occupy the interior space of the vehicle, and it also does not occupy the interior space of the vehicle when the flipping door is in the closed state. There is no need to set additional devices in the interior space of the vehicle to assist passengers in getting on and off, which improves the riding experience of passengers.
[0058] Embodiment 2
[0059] This embodiment provides a three-opening sliding door structure, as Figure 7 shown. Compared with Embodiment 1, the slide rails slidably connected to the horizontal slide door locks are all fixed slide rails. The horizontal slide door is slidably connected to three fixed slide rails through connecting pieces. No slide rail is provided on the flipping door. Specifically, a set position on the outer edge of the horizontal slide door is slidably connected to a fixed slide rail, which is the middle fixed slide rail 13. The top edge of the horizontal slide door is slidably connected to two fixed slide rails, which are the first upper fixed slide rail 11 and the second upper fixed slide rail 12 respectively. Among them, the inner end of the top edge of the horizontal slide door is slidably connected to the first upper fixed slide rail 11 through a connecting piece, and the outer end of the top edge of the horizontal slide door is slidably connected to the second upper fixed slide rail 12 through a connecting piece.
[0060] The structures of the middle fixed slide rail, the first upper fixed slide rail and the second upper fixed slide rail are the same as those of the fixed slide rail in Embodiment 1, and will not be described in detail here.
[0061] The three-opening sliding door structure of this embodiment, as Figure 8 shown. When the door needs to be opened, first drive the horizontal slide door to move from the closed end of the L-shaped groove to the corner position, leaving space for the flipping of the flipping door and the outward movement of the two horizontal slide doors. At this time, the two horizontal slide doors move horizontally outward through the three fixed slide rails until the connecting pieces of the horizontal slide doors move to the unfolded end of the L-shaped groove. At this time, the two horizontal slide doors are opened, and at the same time, the flipping door can flip outward.
[0062] As Figure 9As shown in the figure, when the car door needs to be closed, first flip the door inward to close it. While the flip door is flipping to the closed state, the horizontal sliding doors on both sides slide towards each other. After the flip door is completely closed, the two horizontal sliding doors continue to slide towards each other until the connecting piece moves to the corner position of the L-shaped groove. Then, the two horizontal sliding doors continue to slide along the L-shaped groove until the connecting piece moves to the closed end of the L-shaped groove, completing the closing of the car door.
[0063] Adopting the three-opening sliding door structure of this embodiment, the movable slide rails on the flip door are cancelled, which can better adapt to the flipping movement of the car door and can realize the function of simultaneous sliding opening and closing of the three car doors.
[0064] Embodiment 3
[0065] This embodiment provides a vehicle, as Figure 10 shown, which is provided with the three-opening sliding door structure described in Embodiment 1 or Embodiment 2. The fixed slide rail is fixedly connected to the vehicle frame. The two fixed parts of the flip door 4 are respectively fixed at both ends of the bottom of the upper and lower passenger openings of the vehicle frame. The remaining structures of the vehicle can adopt the existing technologies and will not be described in detail here.
[0066] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
