[0035] The embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0036] As Figures 1 to 7 shown, the door hinge 100 of the embodiment of the present disclosure includes a door page 1, a body page 2 and a bent arm 3. The door page 1 has a door connection part 11 for connecting with a door. The body page 2 has a body connection part 21 for connecting with the body 200. One end of the bent arm 3 is connected to the door page 1, and the other end of the bent arm 3 is rotatably connected to the body page 2. The installation direction of the body connection part 21 is consistent with the length direction of the vehicle, and the position of the body connection part 21 relative to the body 200 is adjustable along the width direction of the vehicle.

[0037] When the door hinge 100 of the embodiment of the present disclosure connects the door and the body 200, the door connection part 11 of the door page 1 is connected to the door to realize the connection between the door hinge 100 and the door; the body connection part 21 of the body page 2 is connected to the body 200 to realize the connection between the door hinge 100 and the body 200. By connecting one end of the bent arm 3 to the door page 1 and the other end of the bent arm 3 to the body page 2 rotatably, the door page 1 can rotate relative to the body page 2 to realize the opening and closing of the door. By setting the installation direction of the body connection part 21 to be consistent with the length direction of the vehicle and making the position of the body connection part 21 relative to the body 200 adjustable along the width direction of the vehicle, when the door is in the closed state, the body connection part 21 can be exposed outside and the position of the body connection part 21 relative to the body 200 can be adjusted along the width direction of the vehicle to realize the surface difference adjustment between the door and the body 200. That is, without opening the door, the surface difference adjustment between the door and the body 200 can be realized, simplifying the surface difference adjustment process between the door and the body 200, improving the installation efficiency of the door, and thus improving the production efficiency of the vehicle.

[0038] In some embodiments, the body connection portion 21 is adjustable in position relative to the vehicle body 200 in the height direction of the vehicle.

[0039] By adjusting the position of the body connection portion 21 relative to the vehicle body 200 in the height direction of the vehicle, the gap between the vehicle door and the vehicle body 200 in the height direction of the vehicle can be adjusted, so that the gap between the vehicle door and the vehicle body 200 in the height direction of the vehicle meets the design requirements.

[0040] Thus, when installing the vehicle door, without opening the vehicle door, the gap adjustment between the vehicle door and the vehicle body 200 in the height direction of the vehicle can be realized, which facilitates the gap adjustment between the vehicle door and the vehicle body 200 in the height direction of the vehicle, further improves the installation efficiency of the vehicle door, and thus further improves the production efficiency of the vehicle.

[0041] Optionally, as Figure 4 shown, the body connection portion 21 includes a body connecting rod 211, and the extending direction of the body connecting rod 211 is consistent with the length direction of the vehicle.

[0042] Wherein, the vehicle body 200 is provided with a body connection hole, the body connection hole extends along the length direction of the vehicle, and the aperture of the body connection hole is larger than the outer diameter of the body connecting rod 211, so that the body connecting rod 211 can move relative to the vehicle body 200 in the width direction and the height direction of the vehicle, thereby adjusting the position of the body connection portion 21 relative to the vehicle body 200 in the width direction and the height direction of the vehicle.

[0043] By setting the body connection portion 21 to include the body connecting rod 211, the body connecting rod 211 can be first inserted into the body connection hole to realize the pre-positioning between the body connection portion 21 and the vehicle body 200, and then the body connecting rod 211 is moved in the width direction and the height direction of the vehicle in the body connection hole to realize the precise positioning between the body connection portion 21 and the vehicle body 200, further improving the installation efficiency of the vehicle door, and thus further improving the production efficiency of the vehicle.

[0044] To make the technical solution of the present disclosure easier to understand, the technical solution of the present disclosure will be further described below by taking the height direction of the vehicle as consistent with the up-down direction, the width direction of the vehicle as consistent with the left-right direction, and the length direction of the vehicle as consistent with the front-back direction as an example. Wherein, the up-down direction is as Figures 1 to 5 shown, the left-right direction is as Figure 2 , Figure 3 and Figure 5 shown, and the front-back direction is as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown.

[0045] For example, as Figure 1 andFigure 4 As shown, the vehicle body connecting rod 2111 extends in the front - rear direction, and the vehicle body connection hole extends in the front - rear direction. The vehicle body connecting rod 211 can move relative to the vehicle body 200 in the left - right direction and the up - down direction, so as to adjust the position of the vehicle body connection part 21 in the left - right direction and the up - down direction, thereby adjusting the surface difference between the door and the vehicle body 200 and the gap between the door and the vehicle body 200 in the up - down direction.

[0046] Optionally, the outer peripheral surface of the vehicle body connecting rod 211 is provided with threads. The vehicle body connecting rod 211 passes through the vehicle body connection hole and is threadedly connected with a fastening nut to realize the connection between the vehicle body connection part 21 and the vehicle body 200.

[0047] Optionally, as Figure 4 shown, the number of the vehicle body connecting rods 211 is multiple, and the multiple vehicle body connecting rods 211 are arranged at intervals in the height direction of the vehicle.

[0048] For example, as Figure 4 shown, the number of the vehicle body connecting rods 211 is three, and the three vehicle body connecting rods 211 are evenly distributed at intervals in the height direction of the vehicle.

[0049] By setting multiple vehicle body connecting rods 211, the connection area between the vehicle body connection part 21 and the vehicle body 200 can be increased, thereby improving the connection reliability between the door and the vehicle body 200, and further improving the reliability of the vehicle.

[0050] In some embodiments, as Figures 1 to 4 shown, the bent arm 3 is rotatably connected to the vehicle body leaf 2 through a pin shaft 5, and the extending direction of the pin shaft 5 is consistent with the height direction of the vehicle. As Figure 3 shown, the bent arm 3 is provided with a bent - arm connection part 31, and the bent - arm connection part 31 is detachably connected to the door leaf 1. The installation direction of the bent - arm connection part 31 is consistent with the width direction of the vehicle, and the position of the bent - arm connection part 31 relative to the door leaf 1 is adjustable along the length direction of the vehicle.

[0051] By adjusting the position of the bent - arm connection part 31 relative to the door leaf 1 along the length direction of the vehicle, the gap between the door and the vehicle body 200 in the front - rear direction can be adjusted, so that the gap between the door and the vehicle body 200 in the front - rear direction meets the design requirements.

[0052] Thus, when installing the door, by adjusting the position of the bent - arm connection part 31 relative to the door leaf 1 along the length direction of the vehicle, the gap adjustment between the door and the vehicle body 200 in the vehicle length direction can be realized, which is convenient for the gap adjustment between the door and the vehicle body 200 in the vehicle length direction, further improving the installation efficiency of the door, and thus further improving the production efficiency of the vehicle.

[0053] In addition, by detachably connecting the door panel 1 to the bent arm 3, when installing the door, the door panel 1 can be first connected to the door to ensure the relative position between the door panel 1 and the door, and the body panel 2 can be connected to the body 200 to ensure the relative position between the body panel 2 and the body 200; then the door panel 1 is connected to the body panel 2, and by ensuring the relative position between the door panel 1 and the body panel 2, the relative position between the door and the body 200 is ensured.

[0054] By detachably connecting the door panel 1 to the bent arm 3, the door and the body 200 can be respectively connected to the door panel 1 and the body panel 2 first, and then the bent arm 3 is connected to the body panel 2, which is beneficial to further improving the installation efficiency of the door, thereby further improving the production efficiency of the vehicle.

[0055] As Figures 1 to 4 shown, the door hinge 100 further includes a gasket 6 and a bushing 7. Both the gasket 6 and the bushing 7 are sleeved on the pin shaft 5, and the bushing 7 is arranged between the gasket 6 and the body panel 2. The bushing is used to reduce the frictional resistance between the body panel 2 and the pin shaft 5.

[0056] Optionally, as Figure 4 shown, the bent arm connecting portion 31 includes a bent arm connecting hole 311. As Figure 6 shown, the door panel 1 is provided with a door connecting hole 13. As Figure 1 and Figure 2 shown, the door hinge 100 includes a bent arm connecting rod 4. The bent arm connecting rod 4 passes through the door connecting hole 13 and the bent arm connecting hole 311 to connect the bent arm connecting portion 31 to the door panel 1. The aperture of the door connecting hole 13 is larger than the outer diameter of the bent arm connecting rod 4.

[0057] By setting the aperture of the door connecting hole 13 to be larger than the outer diameter of the bent arm connecting rod 4, the bent arm connecting rod 4 can move along the length direction of the vehicle within the door connecting hole 13, so as to adjust the position of the bent arm connecting portion 31 relative to the door panel 1 along the length direction of the vehicle, thereby realizing the gap adjustment between the door and the body 200 in the length direction of the vehicle.

[0058] As Figure 2 shown, the bent arm connecting rod 4 is a screw rod. The door hinge 100 further includes a connecting nut 41. The bent arm connecting rod 4 passes through the door connecting hole 13 and the bent arm connecting hole 311 and is threadedly connected to the connecting nut 41 to realize the connection between the bent arm connecting portion 31 and the door panel 1.

[0059] When installing the car door, by screwing the connecting nut 41, the fastening and loosening between the bent arm connecting part 31 and the car door leaf 1 are realized. When adjusting the position between the bent arm connecting part 31 and the car door leaf 1, first make the bent arm connecting part 31 and the car door leaf 1 in a relaxed state, that is, the connecting nut 41 is in an untightened state. At this time, the bent arm connecting part 31 can move relative to the car door leaf 1 along the length direction of the vehicle; then after the bent arm connecting part 31 is adjusted to the designed position, that is, after the gap between the car door and the vehicle body 200 in the length direction of the vehicle meets the design requirements, then tighten the connecting nut 41 to realize the connection between the bent arm connecting part 31 and the car door leaf 1, that is, realize the connection between the car door and the vehicle body 200.

[0060] In some embodiments, such as Figure 1 and Figure 2 shown, the car door leaf 1 is provided with a car door positioning part 12 for positioning and cooperating with the car door.

[0061] When connecting the car door leaf 1 with the car door, the car door positioning part 12 is used for positioning and cooperating with the car door to ensure the assembly accuracy between the car door and the car door leaf 1, thereby ensuring the assembly accuracy between the car door and the vehicle body 200 and improving the assembly accuracy of the vehicle.

[0062] Optionally, as Figure 6 shown, the car door positioning part 12 includes a positioning post 121 for inserting into the car door.

[0063] For example, the car door is provided with a positioning hole, and the positioning post 121 is inserted into the positioning hole and is in positioning cooperation with the positioning hole.

[0064] By setting the car door positioning part 12 as the positioning post 121, not only the structure of the car door positioning part 12 is simple and convenient for processing and manufacturing; but also it is convenient for the car door positioning part 12 to be positioned and cooperate with the car door.

[0065] Such as Figure 1 and Figure 2 shown, the number of the car door connecting parts 11 is multiple, and the car door positioning part 12 is arranged between two adjacent car door connecting parts 11.

[0066] For example, the number of the car door connecting parts 11 is four, and the number of the car door positioning parts 12 is two. One car door positioning part 12 is arranged between two of the car door connecting parts 11, and the other car door positioning part 12 is arranged between the other two car door connecting parts 11.

[0067] By arranging the car door positioning part 12 between two adjacent car door connecting parts 11, the layout of the car door positioning part 12 and the car door connecting part 11 is compact, which is beneficial to reducing the volume and weight of the car door leaf 1, and thus is beneficial to the lightweight and miniaturized design of the car door hinge 100.

[0068] Optionally, as Figure 6As shown in the figure, the door leaf 1 includes a connecting plate 101 and a connecting arm 102. One end of the connecting arm 102 is connected to the connecting plate 101, and the other end of the connecting arm 102 is connected to the bent arm 3. The door connecting portion 11 is provided on the connecting plate 101.

[0069] By setting the door leaf 1 to include the connecting plate 101 and the connecting arm 102, the connecting arm 102 is used to connect the connecting plate 101 and the bent arm 3, and the door connecting portion 11 is provided on the connecting plate 101. In the case where the structure of the door leaf 1 is simple, the connection area between the door leaf 1 and the door can be increased, the connection reliability between the door leaf 1 and the door can be improved, and the reliability of the vehicle can be further improved.

[0070] Optionally, as Figure 6 shown, the connecting plate 101 includes a connected first plate body 1011, a transition plate body 1012, and a second plate body 1013. The extending directions of the first plate body 1011 and the second plate body 1013 both intersect with the extending direction of the transition plate body 1012, and the door connecting portions 11 are provided on both the first plate body 1011 and the second plate body 1013.

[0071] By setting the connecting plate 101 to the above structure, in the case where the structure of the connecting plate 101 is simple, the connection area between the door leaf 1 and the door can be increased, the connection reliability between the door leaf 1 and the door can be further improved, and the reliability of the vehicle can be further improved.

[0072] The vehicle of the embodiment of the present disclosure includes a door hinge 100, a door, and a vehicle body 200. The door hinge 100 is the door hinge 100 described in any one of the above embodiments. The door connecting portion 11 is connected to the door, and the vehicle body connecting portion 21 is connected to the vehicle body 200. Among them, the vehicle body connecting portion 21 can be connected to the side wall of the vehicle body 200.

[0073] Since the vehicle of the embodiment of the present disclosure adopts the door hinge 100 described in any one of the above embodiments, the production efficiency of the vehicle can be improved.

[0074] Optionally, as Figure 5 shown, the vehicle body 200 is provided with a cavity 2001 and a tool hole 2002 for a tool to pass through. Fasteners are provided in the cavity 2001. The vehicle body connecting portion 21 is connected to the vehicle body 200 through the fasteners, and the tool hole 2002 communicates with the cavity 2001. By providing the tool hole 2002 for the tool to pass through in the vehicle body 200, and providing the tool hole 2002 communicating with the cavity 2001 in the vehicle body 200, the tool can pass through the tool hole 2002 and reach the fasteners, realizing the fastening and loosening between the vehicle body connecting portion 21 and the vehicle body 200.

[0075] For example, the fastener is a fixing nut. The body connection part 21 and the vehicle body 200 are connected by the fixing nut. When installing the vehicle door, the tool passes through the tool hole 2002 and reaches the fixing nut, and the tool is used to screw the fixing nut to achieve the fastening and loosening between the body connection part 21 and the vehicle body 200. When adjusting the position between the body connection part 21 and the vehicle body 200, first make the body connection part 21 and the vehicle body 200 in a relaxed state, that is, the fixing nut is in an untightened state. At this time, the body connection part 21 can move relative to the vehicle body 200 in the height direction and width direction of the vehicle. After that, after the body connection part 21 is adjusted to the designed position, that is, the surface difference between the vehicle door and the vehicle body 200 and the gap between the vehicle door and the vehicle body 200 in the height direction of the vehicle meet the design requirements, then use the tool to tighten the fixing nut to achieve the connection between the body connection part 21 and the vehicle body 200.

[0076] By arranging a cavity 2001 and a tool hole 2002 for the tool to pass through on the vehicle body 200, it is convenient to adjust the position between the body connection part 21 and the vehicle body 200, thereby further improving the installation efficiency of the vehicle door and further improving the production efficiency of the vehicle.

The first tooling is matched with the vehicle door, and then the vehicle door is connected to the door connection part 11 to form a vehicle door assembly. The body leaf 2 is connected to the second tooling through the bent arm connection hole 311, and then the second tooling is positioned and matched with the vehicle body 200 to realize the positioning between the body leaf 2 and the vehicle body 200. After that, the vehicle body 200 is connected to the body connection part 21 to complete the connection between the vehicle body 200 and the body leaf 2. Then, the third tooling is used to realize the positioning of the vehicle door assembly and the vehicle body 200. After that, the bent arm 3 is connected to the connecting arm 102 of the door leaf 1, so as to connect the vehicle door assembly and the body leaf 2. Among them, when connecting the vehicle door to the door connection part 11, the door positioning part 12 is used for positioning and matching with the vehicle door to ensure the assembly accuracy of the vehicle door assembly. The installation method of this vehicle door can adopt an automatic assembly and adjustment scheme to meet the surface difference and gap requirements during mass production.

[0079] Among them, when connecting the vehicle door assembly and the body leaf 2, the surface difference between the vehicle door and the vehicle body 200 can be adjusted by adjusting the relative position between the body connection part 21 and the vehicle body 200 in the width direction of the vehicle.
