DETAILED DESCRIPTION

[0023] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein without departing from the scope of the present application, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0024] Referring to Figures 1 to 3 In an embodiment of the present application, a vehicle 10 includes a vehicle body 100, a door 200 and a door opening mechanism 300. The vehicle body 100 has an entrance / exit 110 formed therein, and the door 200 is movably provided at the entrance / exit 110 of the vehicle body 100 by the door opening mechanism 300. The door opening mechanism 300 can at least improve the stability of the door 200 during opening or closing relative to the vehicle body 100.

[0025] Specifically, the door opening mechanism 300 includes a first guide rail 310, a second guide rail 320, and a linkage component 330. The first guide rail 310 is used to be installed on one side of the entrance 110 of the vehicle body 100; the second guide rail 320 is used to be installed on the door 200. The linkage component 330 includes a first link 332 and a second link 334. The first link 332 and the second link 334 are cross-hinged. One end of the first link 332 is rotatably mounted on the second guide rail 320 or the door 200. The other end of the first link 332 is hinged to a vehicle body sliding member 340. The vehicle body sliding member 340 is movably mounted on the first guide rail 310 along its length direction and can deflect relative to the first guide rail 310 around its length direction. One end of the second link 334 is rotatably mounted on the first guide rail 310 or the vehicle body 100. The other end of the second link 334 is hinged to a door sliding member 350. The door sliding member 350 is movably mounted on the second guide rail 320 along its length direction. Specifically, the vehicle body sliding member 340 can deflect relative to the first guide rail 310 around the length direction of the first guide rail 310, so as to drive the linkage component 330 to rotate between the side of the first guide rail 310 facing the entrance 110 and the side of the first guide rail 310 facing away from the vehicle body 100.

[0026] like Figure 3 As shown, when the door is closed, the door 200 is pushed towards the entrance / exit 110 of the vehicle body 100, and the door 200 covers the entrance / exit 110 of the vehicle body 100. At this time, the linkage component 330 is located on the side of the first guide rail 310 facing the entrance / exit 110, that is, the plane formed by the intersection of the first link 332 and the second link 334 is located on the side of the first guide rail 310 facing the entrance / exit 110, which can reduce the space occupied by the door opening mechanism 300 in the closed state and ensure that the door 200 stably covers the entrance / exit 110 of the vehicle body 100. Figure 2As shown, when the door is opened, the door 200 is pulled outwards, the body sliding member 340 moves along the length direction of the first guide rail 310, the door sliding member 350 moves along the length direction of the second guide rail 320, and at this time, the body sliding member 340 is deflected around the length direction of the first guide rail 310, so that the linkage assembly 330 is rotated to the side of the first guide rail 310 away from the vehicle body 100, i.e. to the plane formed after the first connecting rod 332 and the second connecting rod 334 intersecting and intersecting the plane where the entrance 110 is located. At this time, the door 200 can be pushed open relative to the first guide rail 310 through the cooperation of the first connecting rod 332 and the second connecting rod 334, so as to realize the opening of the door 200 relative to the vehicle body 100. And because the first connecting rod 332 and the second connecting rod 334 are cross-hinged, the first connecting rod 332 and the second connecting rod 334 can be linked and supported with each other during the opening and closing of the door, effectively ensuring the stability of the door 200 during the opening and closing of the door.

[0027] In an embodiment, the length direction of the second guide rail 320 is consistent with the length direction of the first guide rail 310. In other embodiments, the length direction of the second guide rail 320 can also be inconsistent with the length direction of the first guide rail 310.

[0028] In an embodiment, a strip-shaped first guide structure is arranged on the outer wall of the first guide rail 310, the length direction of the first guide structure is the length direction of the first guide rail 310, one end of the first guide structure is located on the side of the first guide rail 310 facing the entrance 110 of the vehicle body 100, the other end of the first guide structure is located on the side of the first guide rail 310 away from the vehicle body 100, and the body sliding member 340 is arranged on the first guide structure and can move along the length direction of the first guide structure.

[0029] Because the body sliding member 340 is arranged on the first guide structure, and the other end of the first connecting rod 332 is hinged to the body sliding member 340, when the body sliding member 340 moves along the length direction of the first guide structure, Figure 3 As shown, when the door is closed, the door 200 is pushed towards the entrance 110 of the vehicle body 100, the body sliding member 340 moves to one end of the first guide structure, and because one end of the first guide structure is located on the side of the first guide rail 310 facing the entrance 110 of the vehicle body 100, the body sliding member 340 can be directed towards the entrance 110, so that the first connecting rod 332 and the second connecting rod 334 are located on the side of the body sliding member 340 facing the entrance 110, facilitating the door 200 to cover the entrance 110 of the vehicle body 100. As shown in Figure 2As shown, the vehicle door 200 is pulled outward to move the vehicle body sliding member 340 to the other end of the first guide structure, and since the other end of the first guide structure is located on the side of the first guide rail 310 away from the vehicle body 100, the first connecting rod 332 and the second connecting rod 334 can be rotated to the side of the vehicle body sliding member 340 away from the vehicle body 100 relative to the first guide rail 310 to drive the vehicle door 200 to open relative to the vehicle body 100. The first guide structure can effectively limit the movement and deflection position of the vehicle body sliding member 340 relative to the first guide rail 310, and improve the stability of the movement of the vehicle body sliding member 340 relative to the first guide rail 310.

[0030] Specifically, one end of the first guide structure is located near one end of the second connecting rod 334, and the other end of the first guide structure is located away from one end of the second connecting rod 334. As shown, Figure 2 Since one end of the second connecting rod 334 is rotatably arranged on the first guide rail 310 or the vehicle body 100, when the vehicle body sliding member 340 moves to the other end of the first guide structure, the other end of the first connecting rod 332 connected to the vehicle body sliding member 340 and one end of the second connecting rod 334 are away from each other, which facilitates shortening the distance between the first guide rail 310 and the second guide rail 320, and avoids the vehicle door 200 being too far away from the vehicle body 100 after being opened, which increases the space occupied by the vehicle door 200 after being opened.

[0031] In this embodiment, the first guide structure is a first guide groove 360, which includes a first positioning groove 361, a first limiting groove 362, and a first transition groove 363. The first positioning groove 361 and the first limiting groove 362 are arranged along the length direction of the first guide rail 310, and the first transition groove 363 is arranged between the first positioning groove 361 and the first limiting groove 362 and communicates the first positioning groove 361 and the first limiting groove 362. The opening of the first positioning groove 361 faces the entrance 110 of the vehicle body 100, and the opening of the first limiting groove 362 faces away from the vehicle body 100. One end of the vehicle body sliding member 340 is arranged in the first guide groove 360 from the opening side of the first guide groove 360, and the other end of the vehicle body sliding member 340 is hinged to the first connecting rod 332. The vehicle body sliding member 340 can reciprocate between the first positioning groove 361 and the first limiting groove 362.

[0032] Referring to Figure 2 and Figure 3When the vehicle body sliding member 340 is located in the first positioning slot 361, since the opening of the first positioning slot 361 is towards the entrance 110 of the vehicle body 100, the vehicle body sliding member 340 is located on the side of the first guide rail 310 which is towards the entrance 110, so that the second guide rail 320 and the linkage assembly 330 are located on the side of the first guide rail 310 which is towards the entrance 110, and the closing of the door 200 is realized. When the vehicle body sliding member 340 is moved from the first positioning slot 361 to the first limiting slot 362 through the first transition slot 363, since the opening of the first limiting slot 362 is towards the direction away from the vehicle body 100, the vehicle body sliding member 340 is located on the side of the first guide rail 310 which is away from the vehicle body 100, so that the second guide rail 320 and the linkage assembly 330 are located on the side of the first guide rail 310 which is away from the vehicle body 100, and the opening of the door 200 is realized.

[0033] In an embodiment, the first positioning slot 361 is smoothly transitioned to the first limiting slot 362 through the first transition slot 363. In other embodiments, the first transition slot 363 can be an arc-shaped slot, an inclined slot or a slot with other shapes, as long as the communication between the first positioning slot 361 and the first limiting slot 362 is realized.

[0034] In other embodiments, the first guide structure can also be a guide protrusion, and a sliding slot is formed on one end of the vehicle body sliding member 340 and the other end is hingedly connected with the first connecting rod 332. The guide protrusion is arranged in the sliding slot, and the vehicle body sliding member 340 can be moved and deflected relative to the first guide rail 310 through the cooperation of the sliding slot and the guide protrusion.

[0035] In an embodiment, the door opening mechanism 300 further comprises a first guide rod 370, a first rotating hole 312 is formed in the first guide rail 310, the axis direction of the first rotating hole 312 is the length direction of the first guide rail 310, one end of the first guide rod 370 is arranged in the first rotating hole 312; the first guide slot 360 is in communication with the first rotating hole 312, a vehicle body guide hole is formed on one end of the vehicle body sliding member 340, one end of the vehicle body sliding member 340 passes through the first guide slot 360 and is arranged in the first rotating hole 312, and the axis direction of the vehicle body guide hole is consistent with the axis direction of the first rotating hole 312, one end of the first guide rod 370 can be arranged in the vehicle body guide hole, so that the vehicle body sliding member 340 can be moved along the length direction of the first guide rod 370.

[0036] Since one end of the vehicle body sliding member 340 can be penetrated by the first guide slot 360 in the first rotating hole 312, so that one end of the first guide rod 370 can be penetrated in the vehicle body guide hole, when the vehicle body sliding member 340 moves along the length direction of the first guide slot 360, the penetrating state with the first guide rod 370 can be always kept, further ensuring the stability of the movement of the vehicle body sliding member 340, avoiding the vehicle body sliding member 340 from being separated from the first guide slot 360.

[0037] In the embodiment, the other end of the second connecting rod 334 away from the door sliding member 350 is hinged on the other end of the first guide rod 370. Specifically, one end of the first guide rod 370 is penetrated in the first rotating hole 312 and can rotate in the first rotating hole 312. When the vehicle body sliding member 340 drives the linkage assembly 330 to deflect, so that the second connecting rod 334 can deflect relative to the first guide rail 310 through the first guide rod 370, ensuring the stability of the deflection of the second connecting rod 334. And the first guide rod 370 can provide a connecting installation position for one end of the second connecting rod 334, and only the installation position of the first guide rail 310 needs to be provided on the vehicle body 100 during installation.

[0038] In the embodiment, the other end of the second connecting rod 334 away from the door sliding member 350 is hinged with the first mounting member 372, and the first mounting member 372 is installed on the other end of the first guide rod 370. The second connecting rod 334 can drive the first guide rod 370 to rotate in the first rotating hole 312 through the first mounting member 372. In other embodiments, a circular hole can also be opened on the first mounting member 372, the axis direction of the circular hole is consistent with the length direction of the first guide rod 370, and the other end of the first guide rod 370 is rotatably penetrated in the circular hole, so that the first guide rod 370 can not rotate in the first rotating hole 312.

[0039] In other embodiments, the first guide rod 370 can also be omitted, and the other end of the second connecting rod 334 away from the door sliding member 350 can also be rotatably installed on the vehicle body 100.

[0040] Referring to Figures 1 to 3 In an embodiment, the door sliding member 350 can deflect relative to the second guide rail 320 around the length direction of the second guide rail 320. As shown in Figure 3 When the door 200 is closed, the door 200 pushes in the direction of the entrance 110 of the vehicle body 100, the door 200 covers the entrance 110 of the vehicle body 100, and the second guide rail 320 and the linkage assembly 330 are located on the side of the first guide rail 310 towards the entrance 110. As shown in Figure 2As shown, during the opening of the door 200, the door 200 is pushed outward, and the door sliding member 350 moves along the length direction of the second guide rail 320 while being able to deflect relative to the second guide rail 320 around the length direction of the second guide rail 320. Since the position of the second guide rail 320 is fixed relative to the door 200, the door 200 is able to deflect relative to the door sliding member 350, which facilitates the parallel opening of the door 200 relative to the plane where the doorway 110 is located, and the parallel opening of the door 200 to the side of the vehicle body 100, thereby reducing the occupation of the door 200 to the horizontal space after opening, and improving the safety degree after opening.

[0041] Specifically, the outer wall of the second guide rail 320 is provided with a strip-shaped second guide structure, which is arranged on the outer wall of the second guide rail 320 and has a length direction consistent with the length direction of the second guide rail 320. One end of the second guide structure is located on the plane where the door 200 is located, and the other end of the second guide structure is located on the side of the second guide rail 320 facing the vehicle body 100. The door sliding member 350 is arranged on the second guide structure and is able to move along the length direction of the second guide structure.

[0042] As shown, Figure 3 When the door 200 is in a closed state, the door sliding member 350 moves to one end of the second guide structure, and the vehicle body sliding member 340 moves to one end of the first guide structure. At this time, one end of the first guide structure is arranged opposite to one end of the second guide structure. Since one end of the second guide structure is located on the plane where the door 200 is located, the door 200 effectively covers the doorway 110 of the vehicle body 100. Figure 2 When the door 200 is opened, the door sliding member 350 moves to the other end of the second guide structure, and the vehicle body sliding member 340 moves to the other end of the first guide structure. At this time, the other end of the first guide structure is arranged opposite to the other end of the second guide structure. Since the other end of the first guide structure is located on the side of the second guide rail 320 facing the vehicle body 100, and the second guide rail 320 is arranged on the door 200, the rotation of the door 200 relative to the door sliding member 350 is ensured, so that the door 200 is opened parallel to the vehicle body 100. By arranging the second guide structure, the stability of the movement and deflection of the door sliding member 350 is improved, and the parallel opening of the door 200 relative to the vehicle body 100 is ensured.

[0043] Specifically, one end of the first guide structure is close to one end of the second connecting rod 334, and one end of the second guide structure is close to one end of the first connecting rod 332. As shown, Figure 2As shown, after the door 200 is opened, it can ensure that one end of the first link 332 connected to the body sliding member 340 is far away from one end of the second link 334, and one end of the second link 334 connected to the door sliding member 350 is far away from one end of the first link 332. This facilitates shortening the distance between the first guide rail 310 and the second guide rail 320, and prevents the door 200 from being too far away from the body 100 after opening, which would increase the space occupied by the door 200 after opening.

[0044] In this embodiment, the second guide structure is a second guide groove 380, which includes a second positioning groove 381, a second limiting groove 382, ​​and a second transition groove 383. The second positioning groove 381 and the second limiting groove 382 are spaced apart along the length of the second guide rail 320. The second transition groove 383 is disposed between the second positioning groove 381 and the second limiting groove 382 and connects the second positioning groove 381 and the second limiting groove 382. The opening of the second positioning groove 381 faces the plane where the door 200 is located, and the opening of the second limiting groove 382 faces the direction from the second guide rail 320 toward the vehicle body 100. One end of the door sliding member 350 is disposed in the second guide groove 380 through the opening side of the second guide groove 380, and the other end of the door sliding member 350 is hinged to the second connecting rod 334. The door sliding member 350 can reciprocate between the second positioning groove 381 and the second limiting groove 382. Specifically, the first positioning groove 361 is closer to the end of the second connecting rod 334 relative to the first limiting groove 362, and the second positioning groove 381 is closer to the end of the first connecting rod 332 relative to the second limiting groove 382.

[0045] like Figure 3 As shown, when the door sliding member 350 is located within the second positioning groove 381, since the opening of the second positioning groove 381 faces the plane where the door 200 is located, the door sliding member 350 is located on the plane where the door 200 is located, thus achieving the closing of the door 200. Figure 2 As shown, when the door sliding member 350 is located within the second limiting groove 382, ​​since the opening of the second limiting groove 382 faces the direction of the second guide rail 320 towards the vehicle body 100, the door sliding member 350 is located on the side of the second guide rail 320 facing the vehicle body 100, thus enabling the door 200 to open. The second guide groove 380 effectively restricts the movement and deflection position of the door sliding member 350, thereby restricting the rotation and movement position of the door 200 relative to the vehicle body 100.

[0046] In an embodiment, the second positioning groove 381 is smoothly connected to the second limiting groove 382 through the second transition groove 383. In other embodiments, the second transition groove 383 can also be an arc-shaped groove, an inclined groove or a groove with other shapes, as long as the communication between the second positioning groove 381 and the second limiting groove 382 can be achieved.

[0047] In other embodiments, the second guide structure can also be a guide protrusion, and a sliding groove is formed on one end of the door sliding member 350 and the other end is hingedly connected to the second connecting rod 334. The guide protrusion is arranged in the sliding groove, and the door sliding member 350 can move and deflect relative to the second guide rail 320 through the cooperation of the sliding groove and the guide protrusion.

[0048] In an embodiment, the door opening mechanism 300 further comprises a second guide rod 390, a second rotating hole 322 is formed in the second guide rail 320, the axis direction of the second rotating hole 322 is the length direction of the second guide rail 320, one end of the second guide rod 390 is arranged in the second rotating hole 322; the second guide groove 380 is in communication with the second rotating hole 322, a door guide hole is formed on one end of the door sliding member 350, one end of the door sliding member 350 passes through the second guide groove 380 and is arranged in the second rotating hole 322, and the axis direction of the door guide hole is consistent with the axis direction of the second rotating hole 322, one end of the second guide rod 390 can be arranged in the door guide hole, so that the door sliding member 350 can move along the length direction of the second guide rod 390.

[0049] Since one end of the door sliding member 350 can be arranged in the second rotating hole 322 through the second guide groove 380, one end of the second guide rod 390 can be arranged in the door guide hole, when the door sliding member 350 moves along the length direction of the second guide groove 380, it can always maintain the arrangement state with the second guide rod 390, further ensuring the stability of the movement of the door sliding member 350, and avoiding the door sliding member 350 from being separated from the second guide groove 380.

[0050] In the embodiment, the other end of the first connecting rod 332 away from the vehicle body sliding member 340 is hinged to the other end of the second guide rod 390. Specifically, the other end of the second guide rod 390 is threaded into the second rotating hole 322 and can rotate in the second rotating hole 322. When the vehicle body sliding member 340 drives the door sliding member 350 to deflect relative to the second guide rail 320 through the linkage assembly 330, the first connecting rod 332 can deflect relative to the second guide rail 320 through the second guide rod 390, ensuring the stability of the deflection of the first connecting rod 332. The second guide rod 390 can provide a connecting and mounting position for one end of the first connecting rod 332, and only the mounting position of the second guide rail 320 needs to be provided on the door 200 during installation.

[0051] In the embodiment, the other end of the first connecting rod 332 away from the vehicle body sliding member 340 is hinged to the second mounting member 392, which is mounted on the other end of the second guide rod 390. The first connecting rod 332 can drive the second guide rod 390 to rotate in the second rotating hole 322 through the second mounting member 392. In other embodiments, a circular hole can also be formed in the second mounting member 392, the axis direction of the circular hole being consistent with the length direction of the second guide rod 390, and the other end of the second guide rod 390 can be rotatably threaded into the circular hole. When the second guide rod 390 enters the second rotating hole 322, it can not rotate.

[0052] In other embodiments, the second guide rod 390 can also be omitted, and the other end of the first connecting rod 332 away from the door sliding member 350 can also be rotatably mounted on the door 200.

[0053] In the embodiment, the first connecting rod 332 is in a strip-shaped structure, and the second connecting rod 334 is in a strip-shaped structure. One plate surface of the first connecting rod 332 is arranged to face one plate surface of the second connecting rod 334. As shown in the figure, since the first connecting rod 332 and the second connecting rod 334 are both in a strip-shaped structure, when the door 200 is closed, the first connecting rod 332 and the second connecting rod 334 intersect and have a smaller thickness, which can further reduce the occupation of the linkage assembly 330 to the horizontal space in the closed state of the door 200. In other embodiments, the first connecting rod 332 and the second connecting rod 334 can also be in a rod-shaped structure or other shapes. Figure 3
