DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0027] like Figures 1 to 3 As shown, an embodiment of the utility model provides a door hinge structure, including a mounting plate 100 provided with an avoidance hole 110 and at least one hinge 200; a hinge shaft is provided on the side of the mounting plate 100 facing away from the door body 300; the hinge 200 includes an arcuate connecting section 210, a rotating end 220 rotatably connected to the hinge shaft, and a connecting end 230 fixedly connected to the door body 300; one end of the arcuate connecting section 210 is connected to the connecting end 230, and the other end of the arcuate connecting section 210 passes through the avoidance hole 110 and is connected to the rotating end 220.

[0028] In this embodiment, the door hinge structure can be applied to the door structure of a carrier. The carrier includes but is not limited to a vehicle (such as a flying car) or an aircraft. The door structure includes but is not limited to a hatchback door or a side-opening door. The door body 300 is mounted around the passenger entrance on the carrier fuselage through the door hinge structure, so that the door body 300 can cover the passenger entrance on the carrier fuselage when rotating relative to the mounting plate 100. The mounting plate 100 can be mounted on the carrier fuselage, or can be an integrally formed structure with the fuselage.

[0029] It can be understood that the hinge 200 is fixedly connected to the door body 300 through the connection end 230 and is rotatably connected to the hinge shaft through the rotation end 220, so that a kinematic pair rotating around the hinge shaft is formed between the door body 300 and the mounting plate 100. The door body 300 can rotate around the hinge shaft driven by the hinge 200. At this time, the door body 300 rotates relative to the carrier body, thereby covering the passenger entrance on the carrier body or opening the member entrance, thereby realizing the opening and closing of the passenger entrance by the door body 300.

[0030] Among them, an avoidance hole 110 is provided on the mounting plate 100 for the arc-shaped connecting section 210 of the hinge 200 to pass through, and the connecting end 230 of the hinge 200 is connected to the hatch body 300, and the rotating end 220 is rotatably installed on the hinge shaft located on the side of the mounting plate 100 away from the hatch body 300. In this way, after the arc-shaped connecting section 210 passes through the avoidance hole 110, the connecting end 230 and the rotating end 220 on the hinge 200 are respectively located on opposite sides of the mounting plate 100. Furthermore, while avoiding interference between the hinge 200 and the mounting plate 100, the occupation of the passenger space between the mounting plate 100 and the hatch body 300 by the hinge 200 is also reduced. And because when the arc-shaped connecting section 210 rotates around the hinge axis, its moving trajectory during the rotation process is also an arc-shaped trajectory that moves around the edge of the avoidance hole 110 and has a certain spacing distance from the edge of the avoidance hole 110, therefore, the hinge 200 will not contact the edge of the avoidance hole 110 during the rotation process, thereby avoiding interference between the hinge 200 and the mounting plate 100. At the same time, the design of the arc-shaped connecting section 210 can also enable the hatch body 300 to have a larger rotation angle relative to the mounting plate 100, that is, the hatch body 300 of the carrier has a larger opening angle.

[0031] It can be understood that the shape of the arc-shaped connecting section 210 can be set according to actual conditions, as long as the door body 300 can have a larger opening angle relative to the mounting plate 100 while avoiding interference between the hinge 200 and the mounting plate 100. The connection method between the connecting end 230 and the door body 300 includes but is not limited to one or more of the methods such as screw connection, welding or clamping, as long as the door body 300 can be stably mounted on the connecting end 230. The shape of the avoidance hole 110 can be set according to actual conditions, as long as it does not interfere with the hinge 200 when the hinge 200 rotates. The hinge 200 can be provided with a structural hole for reducing the weight of the hinge 200, as long as it does not affect the structural strength of the hinge 200 supporting the door body 300. In one embodiment, the mounting plate 100 is provided with a mounting seat 120; the hinge shaft is provided on the mounting seat 120; and the rotating end 220 is rotatably connected to the mounting plate 100 through the hinge shaft on the mounting seat 120.

[0032] In the present invention, an avoidance hole 110 for the arc-shaped connecting section 210 of the hinge 200 to pass through is provided on the mounting plate 100, and the connecting end 230 of the hinge 200 is connected to the door body 300, and the rotating end 220 is rotatably mounted on the hinge shaft located on the side of the mounting plate 100 away from the door body 300, thereby reducing the occupation of the passenger space between the mounting plate 100 and the door body 300 by the hinge 200 while avoiding interference between the hinge 200 and the mounting plate 100, and the hinge The size of 200 is small, which will not occupy too much space in the cabin, nor will it affect the installation of other devices in the cabin, thereby improving space utilization; in addition, the setting of the arc-shaped connecting section 210 on the hinge 200 can prevent the hinge 200 from contacting the edge of the avoidance hole 110 during the process, that is, avoiding interference between the hinge 200 and the mounting plate 100, and at the same time allowing the hatch body 300 to have a larger rotation angle relative to the mounting plate 100, that is, allowing the hatch body 300 of the carrier to have a larger opening angle.

[0033] like Figures 1 to 3As shown, in one embodiment, the arc-shaped connecting section 210 is an arc section, and the hinge axis is perpendicular to the arc section and passes through the center of the arc section. It can be understood that the hinge axis is perpendicular to the arc section and passes through the center of the arc section, that is, when the hinge 200 rotates around the hinge axis, the arc section always moves on the circumference corresponding to the same circular trajectory (the radius of the circle is the distance between the arc section and the hinge axis) with the hinge axis as the center; therefore, when the hinge 200 rotates around the hinge axis, the distance between the arc section and the hinge axis (that is, the radius of the above-mentioned circular trajectory) remains unchanged, thereby preventing the arc section from contacting and interfering with the edge of the avoidance hole 110 when rotating around the hinge axis.

[0034] like Figure 3 As shown, in one embodiment, the center angle corresponding to the arc segment is 60 degrees to 120 degrees. Further, the center angle corresponding to the arc segment is 90 degrees. It can be understood that the larger the center angle corresponding to the arc segment, the larger the rotation angle of the hinge 200. The center angle corresponding to the arc segment can be set according to actual conditions. In this embodiment, the center angle corresponding to the arc segment is 60 degrees to 120 degrees, so that when the hinge 200 rotates within the range of 60 degrees to 120 degrees relative to the hinge axis, the distance between the arc segment and the hinge axis remains unchanged and does not interfere with the mounting plate 100. In addition, the rotating end 220 is rotatably connected to the mounting plate 100 via the hinge shaft on the mounting seat 120. There is a certain distance between the hinge shaft and the mounting plate 100, and the hinge 200 can continue to rotate around the hinge shaft. Therefore, the hinge 200 can continue to rotate relative to the hinge shaft within a range greater than the above-mentioned central angle. That is, the structural design of the hinge 200 allows the opening angle of the door body 300 to be greater than the central angle corresponding to the above-mentioned arc-shaped connecting section 210, thereby facilitating the occupants to enter the occupant space and improving the occupant comfort.

[0035] like Figure 1As shown, in one embodiment, the door hinge structure further includes a driving assembly 400, and the driving assembly 400 is connected to the rotating end 220 of at least one of the hinges 200, so as to drive the hinge 200 to rotate around the hinge axis, thereby realizing the opening and closing of the door body 300. It can be understood that the door hinge structure can include one or more hinges 200; in this embodiment, the driving assembly 400 can be connected to one of the hinges 200, and then the hinge 200 connected thereto is driven to rotate around the hinge axis through the driving assembly 400, thereby driving the door body 300 to rotate, and making other hinges 200 not connected to the driving assembly 400 also rotate with the door body 300, thereby realizing the synchronous rotation of all hinges 200 around the hinge axis. It can be understood that the door hinge structure is provided with multiple hinges 200 to strengthen the strength of the door hinge structure and improve the reliability of the door opening and closing. In the present embodiment, the connection ends 230 of all the hinges 200 are connected to the door body 300, the rotating ends 220 of all the hinges 200 are located on the side of the mounting plate 100 away from the door body 300, and the driving assembly 400 is also located on the side of the mounting plate 100 away from the door body 300. Therefore, the driving assembly 400 is connected to the rotating end 220, so that the driving assembly 400 will not interfere with the rotation of the arc-shaped connecting section 210 of the hinge 200 in the avoidance hole 110, and can also reduce the occupation of the passenger space.

[0036] like Figure 1 As shown, in one embodiment, the driving assembly 400 includes a connecting rod assembly 410 and a driving member 420; a fixed end 421 of the driving member 420 is connected to the mounting plate 100; one end of the connecting rod assembly 410 is rotatably connected to the driving end 422 of the driving member 420, and the other end of the connecting rod assembly 410 is rotatably connected to at least one of the arc-shaped connecting segments 210; the driving member 420 is used to drive the connecting rod assembly 410 to drive the hinge 200 to rotate around the hinge axis. It can be understood that a first rotating shaft is provided on the side of the mounting plate 100 away from the door body 300, and the connecting rod assembly 410 is rotatably connected to the mounting plate 100 through the first rotating shaft, thereby forming a kinematic pair rotating around the first rotating shaft. Further, the first rotating shaft is arranged in parallel with the hinge axis, so as to avoid interference between the hinge 200 and the connecting rod assembly 410 when rotating. In this embodiment, the driving member 420 performs linear motion, and the connecting rod assembly 410 converts the linear motion of the driving member 420 into rotational motion, thereby driving the hinge 200 to rotate around the hinge axis.

[0037] In one embodiment, the driving member 420 is a pneumatic pull rod or an electric pull rod; the fixed end 421 of the driving member 420 is rotatably connected to the mounting plate 100. It can be understood that the driving member 420 can be a pneumatic pull rod, and a buckle can be provided on the carrier body. The door body 300 can drive the connecting rod assembly 410 through the hinge 200 to compress the pneumatic pull rod, so that the door body 300 covers the passenger entrance, and then is connected to the carrier body through the buckle, so as to close the door body 300; after the buckle is connected, the door body 300 can drive the connecting rod assembly 410 to drive the hinge 200 and then drive the door body 300 to open through the compression force stored in the pneumatic pull rod. The driving member 420 may also be an electric pull rod. When the electric pull rod receives a signal to open or close the door, the electric pull rod may extend or retract, thereby driving the connecting rod assembly 410 to rotate and driving the hinge 200 to rotate, thereby driving the door body 300 to rotate around the hinge axis, thereby realizing the opening and closing of the door body 300.

[0038] like Figure 1 As shown, in one embodiment, a second rotating shaft is further provided on the side of the mounting plate 100 away from the door body 300, and the driving member 420 is rotatably connected to the mounting plate 100 via the second rotating shaft. In one embodiment, the hinge shaft, the first rotating shaft and the second rotating shaft are parallel to each other, so as to avoid mutual interference between the hinge 200, the connecting rod assembly 410 and the driving member 420 during rotation.

[0039] like Figure 4 As shown, in one embodiment, the connecting rod assembly 410 includes a first connecting rod 411 and a second connecting rod 412; the first connecting rod 411 includes a first connecting section 4111, a supporting section 4112 and a second connecting section 4113 connected in sequence; the supporting section 4112 is rotatably mounted on the mounting plate 100; one end of the first connecting section 4111 away from the supporting section 4112 is rotatably connected to the driving end 422 of the driving member 420; one end of the second connecting section 4113 away from the supporting section 4112 is rotatably connected to the second connecting rod 412; one end of the second connecting rod 412 away from the second connecting section 4113 is rotatably connected to the rotating end 220. It can be understood that the supporting section 4112 is rotatably connected to the mounting plate 100 via the first rotating shaft. The first connecting rod 411 is used to convert the linear motion of the driving member 420 into rotational motion, and the second connecting rod 412 is used to transmit the rotational motion converted by the first connecting rod 411 to the rotating end 220 of the hinge 200, thereby driving the hinge 200 to rotate.

[0040] In one embodiment, the first connecting section 4111 and the second connecting section 4113 are arranged at a preset angle, and the preset angle is less than 180 degrees. It can be understood that the first connecting rod 411 and the driving member 420 are both installed on the mounting plate 100, that is, the first connecting rod 411 and the driving member 420 are relatively located in a smaller space range. Therefore, in order to keep the linear motion direction of the driving member 420 and the tangent direction of the rotational motion of the first connecting rod 411 as small as possible within the range of the angle, the first connecting section 4111 and the second connecting section 4113 need to be arranged at a preset angle less than 180 degrees, so as to improve the space utilization rate.

[0041] like Figure 1 As shown, an embodiment of the utility model further provides a door structure, including a door body 300 and the door hinge structure. The specific structure of the door hinge structure can refer to the above embodiment, and will not be repeated here. The door structure can be a hatchback door or a side-opening door, etc. The door body 300 of the door structure is installed on the fuselage through the door hinge structure to realize the opening and closing of the door body 300 to the passenger entrance.

[0042] In the hatch structure of the above embodiment of the utility model, the hatch hinge structure is provided with an avoidance hole 110 for the arc-shaped connecting section 210 of the hinge 200 to pass through on the mounting plate 100, and the connecting end 230 of the hinge 200 is connected to the hatch body 300, and the rotating end 220 is rotatably mounted on the hinge shaft located on the side of the mounting plate 100 away from the hatch body 300, thereby reducing the occupation of the occupant space between the mounting plate 100 and the hatch body 300 by the hinge 200 while avoiding interference between the hinge 200 and the mounting plate 100. Moreover, the hinge 200 is small in size and will not occupy too much space in the cabin, nor will it affect the installation of other devices in the cabin, thereby improving space utilization. In addition, the arrangement of the arc-shaped connecting section 210 on the hinge 200 can prevent the hinge 200 from contacting the edge of the avoidance hole 110 during the process, that is, it can prevent the hinge 200 from interfering with the mounting plate 100, and at the same time, it can allow the hatch body 300 to have a larger rotation angle relative to the mounting plate 100, that is, the hatch body 300 of the carrier has a larger opening angle.

[0043] An embodiment of the utility model further provides a transport device, comprising the cabin door structure.

[0044] In the carrier device of the above embodiment of the utility model, the hatch hinge structure is provided with an avoidance hole 110 for the arc-shaped connecting section 210 of the hinge 200 to pass through on the mounting plate 100, and the connecting end 230 of the hinge 200 is connected to the hatch body 300, and the rotating end 220 is rotatably mounted on the hinge shaft located on the side of the mounting plate 100 away from the hatch body 300, thereby reducing the occupation of the passenger space between the mounting plate 100 and the hatch body 300 by the hinge 200 while avoiding interference between the hinge 200 and the mounting plate 100. Moreover, the hinge 200 is small in size and will not occupy too much space in the cabin, nor will it affect the installation of other devices in the cabin, thereby improving space utilization. In addition, the arrangement of the arc-shaped connecting section 210 on the hinge 200 can prevent the hinge 200 from contacting the edge of the avoidance hole 110 during the process, that is, it can prevent the hinge 200 from interfering with the mounting plate 100, and at the same time, it can allow the hatch body 300 to have a larger rotation angle relative to the mounting plate 100, that is, the hatch body 300 of the carrier has a larger opening angle.

[0045] The above are merely embodiments of the door hinge structure, door structure and carrier equipment of the present invention and are not intended to limit the present invention.
