Description

Technical Field

[0001] This application relates to the field of door adjustment technology, and in particular to a hinge structure, door assembly, and vehicle. Background Technology

[0002] Currently, during the rough assembly of the four-bar hinge with the car door, the four-bar hinge is fitted against the Y-axis surface of the car body, and then the car door is assembled onto the four-bar hinge. The four-bar hinge is bolted through holes in both the X and Z directions relative to the car body, allowing for adjustable sliding. During installation, the Z-axis position of the hinge relative to the car body is typically adjusted to meet the requirements of the Z-axis relative position control fixture between the door and the side panel. Similarly, the X-axis position of the door and hinge is adjusted to meet the requirements of the X-axis relative position control fixture between the door and the side panel. However, the Y-axis sliding adjustment of the four-bar hinge is achieved through X-axis adjustment of a single arm of the side hinge on the car body. This setup couples the door-side Y-axis surface difference (DTS) guarantee with the four-bar hinge's own closing function guarantee. Even minor X-axis adjustments between the two arms of the four-bar hinge on the car body side significantly affect both the closing function and the surface difference. Utility Model Content

[0003] To address the issue of inconvenient Y-axis adjustment during rough assembly of a four-bar hinge with a vehicle door, embodiments of this application provide a hinge structure, a door assembly, and a vehicle that facilitate Y-axis adjustment of the four-bar hinge.

[0004] This application provides a hinge structure comprising a first hinge body, a first connecting member, and a second connecting member. One end of the first hinge body is rotatably connected to a door body, and the other end is rotatably connected to a vehicle body. The door body is located on one side of the vehicle body along a first direction. One end of the first connecting member is connected to the door body, and the other end is movably connected to the first hinge body along the first direction. One end of the second connecting member is connected to the vehicle body, and the other end is movably connected to the first hinge body along a second direction and a third direction. The first direction, the second direction, and the third direction intersect each other.

[0005] Understandably, the first hinge body is movably connected to the first hinge body along the first direction via the first connecting member, allowing the first hinge body to be adjustable relative to the door body along the first direction. Furthermore, the second connecting member is movably connected to the first hinge body along the second and third directions, enabling the first hinge body to be adjusted relative to the vehicle body along the second and third directions. This allows for independent adjustment of the first hinge body in the first, second, and third directions, eliminating the need to adjust the hinge's Y-direction by adjusting its X-direction, thus facilitating the rough assembly of the hinge with the door to meet assembly requirements.

[0006] In one embodiment, the first hinge body is provided with a first adjustment hole, and the first connector can move within the first adjustment hole along the first direction.

[0007] In one embodiment, the first hinge body is provided with a connecting portion, the connecting portion having the first adjustment hole, and the connecting portion being connected to the first hinge body or integrally formed on the first hinge body.

[0008] In one embodiment, the hinge structure further includes a reinforcing member connected to the door body, and the end of the first connecting member away from the first hinge body is connected to the reinforcing member.

[0009] In one embodiment, the first hinge body is provided with a second adjustment hole, and the second connector can move within the second adjustment hole along the second direction and along the third direction.

[0010] In one embodiment, the hinge structure further includes a first locking member configured to fix the first connector relative to the first hinge body.

[0011] In one embodiment, the first connector includes a protrusion and a body portion, and the first locking member clamps at least a portion of the body portion between the first locking member and the protrusion.

[0012] In one embodiment, the hinge structure further includes a second hinge body and a third connector. One end of the second hinge body is rotatably connected to the door body and the other end is rotatably connected to the vehicle body. One end of the third connector is connected to the vehicle body and the other end is movably connected to the second hinge body along the second direction and the third direction.

[0013] This application embodiment also provides a door assembly connected to the vehicle body, including a door body and a hinge structure as described above, wherein one end of the hinge structure is connected to the door body and the other end is connected to the vehicle body.

[0014] Understandably, when a door assembly with the aforementioned hinge structure is roughly assembled with the door, the hinge structure can be adjusted independently in the first, second, and third directions, making assembly easier.

[0015] This application also provides a vehicle, including a body body and a door assembly as described above, the door assembly being connected to the body body.

[0016] It is understandable that when installing doors in vehicles including the aforementioned door assemblies, the position of the hinge structure can be adjusted to make the doors easier to install and adjust, thereby improving the efficiency of door installation and adjustment, and thus improving vehicle production efficiency.

[0027] like Figures 1 to 3 As shown in the figure, this application embodiment provides a hinge structure 100, which includes a first hinge body 1, a first connector 2, and a second connector 3. One end of the first hinge body 1 is rotatably connected to the door body 201, and the other end is rotatably connected to the vehicle body 301.

[0028] For ease of reading, this application introduces the terms first direction Y, second direction X, and third direction Z to describe the embodiments of this application. The first direction Y, second direction X, and third direction Z can be three non-parallel straight lines in space; further, the first direction Y, second direction X, and third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the description will use the first direction Y as the Y-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Z as the Z-axis direction of the three-dimensional coordinate system as examples. Simultaneously, the first direction Y also represents the vehicle body's Y-direction, i.e., the width direction of the vehicle body; the second direction X represents the vehicle body's X-direction, i.e., the length direction of the vehicle body; and the third direction Z represents the vehicle body's Z-direction, i.e., the height direction of the vehicle body.

[0029] Along the first direction Y, the door body 201 is located on one side of the vehicle body 301. One end of the first connector 2 is connected to the door body 201, and the other end is movably connected to the first hinge body 1 along the first direction Y. One end of the second connector 3 is connected to the vehicle body 301, and the other end is movably connected to the first hinge body 1 along the second direction X and the third direction Z.

[0030] In this embodiment, the door body 201 and the vehicle body 301 are spaced apart along the first direction Y and can be connected by a hinge structure 100. The hinge structure 100 includes a first hinge body 1 and a second hinge body 6, which are arranged parallel to each other to form a four-bar hinge structure. One end of the first hinge body 1 is rotatably connected to the door body 201, and the other end is rotatably connected to the vehicle body 301. One end of the second hinge body 6 is rotatably connected to the door body 201, and the other end is rotatably connected to the vehicle body 301. Thus, the door body 201 is connected to the vehicle body 301 via the hinge structure 100, and the door body 201 can rotate relative to the vehicle body 301 to open and close the door.

[0031] The first connecting member 2 can be a lockable positioning pin, which can be movably connected to the first hinge body 1 along the first direction Y. No further restrictions are imposed here. One end of the first connecting member 2 is movably connected to the first hinge body 1 along the first direction Y, allowing adjustment of the position of the first connecting member 2 relative to the first hinge body 1 in the first direction Y. After adjustment, the first connecting member 2 can be fixed relative to the first hinge body 1. The other end of the first connecting member 2 is fixedly connected to the door body 201. Adjusting the position of the first connecting member 2 relative to the first hinge body 1 allows adjustment of the position of the door body 201 connected to the first hinge body 1 relative to the first hinge body 1 in the first direction Y, thus facilitating the assembly of the door body 201.

[0032] The second connecting member 3 can be a bolt, which can be movably connected to the first hinge body 1 along the second direction X and the third direction Z. No further restrictions are imposed here. One end of the second connecting member 3 is movably connected to the first hinge body 1 along the second direction X and the third direction Z, allowing adjustment of the position of the second connecting member 3 relative to the first hinge body 1 in the second direction X and the third direction Z. After adjustment, the second connecting member 3 can be fixed relative to the first hinge body 1. The other end of the second connecting member 3 is fixedly connected to the vehicle body 301. Adjusting the position of the second connecting member 3 relative to the first hinge body 1 allows adjustment of the position of the vehicle body 301 relative to the first hinge body 1 in the second direction X and the third direction Z, facilitating the assembly of the vehicle body 301. Simultaneously, it allows the position of the door body 201 connected to the hinge structure 100 relative to the vehicle body 301 to be adjustable, ensuring that the installation meets requirements.

[0033] It is understandable that the first connecting member 2 is movably connected to the first hinge body 1 along the first direction Y, making the first hinge body 1 adjustable relative to the door body 201 along the first direction Y. Furthermore, the second connecting member 3 is movably connected to the first hinge body 1 along the second direction X and the third direction Z, allowing the first hinge body 1 to be adjusted relative to the vehicle body 301 along the second direction X and the third direction Z. This enables independent adjustment of the first hinge body 1 in the first direction Y, the second direction X, and the third direction Z, eliminating the need to adjust the hinge's Y direction by adjusting its X direction. This facilitates meeting assembly requirements during rough assembly of the hinge and the door.

[0034] In one embodiment, the hinge structure 100 further includes a third connector 7, one end of which is connected to the vehicle body 301, and the other end is movably connected to the second hinge body 6 along the second direction X and the third direction Z.

[0035] In this embodiment, one end of the second hinge body 6 is fixedly connected to the door body 201, and the other end is movably connected to the vehicle body 301 along the second direction X and the third direction Z via a third connector 7. The third connector 7 can be a bolt, which can be movably connected to the second hinge body 6 along the second direction X and the third direction Z; no further restrictions are imposed here. One end of the third connector 7 is movably connected to the second hinge body 6 along the second direction X and the third direction Z, allowing adjustment of the position of the third connector 7 relative to the second hinge body 6 in the second direction X and the third direction Z. After adjustment, the third connector 7 can be fixed relative to the second hinge body 6. The other end of the third connector 7 is fixedly connected to the vehicle body 301. Adjusting the position of the third connector 7 relative to the second hinge body 6 allows adjustment of the position of the vehicle body 301 relative to the second hinge body 6 in the second direction X and the third direction Z, thereby facilitating the assembly of the vehicle body 301.

[0036] Understandably, the second hinge body 6 can also be adjusted relative to the body body 301 in the second direction X and the third direction Z via the third connector 7, so that the hinge structure 100 can better adjust its position relative to the body body 301, making the door body 201 easier to install and adjust.

[0037] Further integration Figure 4 and Figure 5 As shown, in one embodiment, a first adjustment hole 111 is provided on the first hinge body 1, and the first connector 2 can move within the first adjustment hole 111 along the first direction Y.

[0038] In this embodiment, the first adjustment hole 111 can be an elongated hole, so that the first connector 2 can move within the first adjustment hole 111 along the first direction Y. When the first connector 2 is located within the first adjustment hole 111, along the second direction X, the first connector 2 abuts against the hole wall of the first adjustment hole 111 to achieve good adjustment of the first connector 2.

[0039] It is understandable that the first connecting member 2 can be adjusted relative to the first hinge body 1 along the first direction Y by the setting of the first adjustment hole 111, and the displacement of the first connecting member 2 in the second direction X is restricted by the hole wall of the first adjustment hole 111, making the adjustment of the first connecting member 2 more stable and reliable.

[0040] In one embodiment, the first hinge body 1 is provided with a connecting part 11, and the connecting part 11 has a first adjustment hole 111. The connecting part 11 is connected to the first hinge body 1 or integrally formed on the first hinge body 1.

[0041] In this embodiment, the connecting part 11 can be plate-shaped, and a first adjustment hole 111 can be formed on the connecting part 11 to facilitate the adjustment and connection of the first connector 2. The projection shape of the first adjustment hole 111 on the connecting part 11 can be oblong. Two first adjustment holes 111 can be provided at intervals along the second direction X. The connecting part 11 and the rest of the first hinge body 1 can be integrally formed or separately formed, and the connecting part 11 is fixedly connected to the rest of the first hinge body 1.

[0042] It is understandable that the first hinge body 1 with the connecting part 11 allows the first adjustment hole 111 to be opened on the connecting part 11, thereby making the first connecting member 2 easy to adjust.

[0043] In one embodiment, the hinge structure 100 further includes a reinforcing member 4, which is connected to the door body 201, and the end of the first connecting member 2 away from the first hinge body 1 is connected to the reinforcing member 4.

[0044] In this embodiment, the reinforcing member 4 can be a plate-like structure, and an L-shaped reinforcing plate can be selected to connect to the door body 201 and the connecting part 11. The reinforcing member 4 can be provided with a positioning hole 41 so that the end of the first connecting member 2 away from the first hinge body 1 passes through the positioning hole 41 and is positioned by the positioning hole 41, so that the first connecting member 2 can be connected to the reinforcing member 4.

[0045] Understandably, the reinforcing member 4 has sufficient strength to withstand the forces exerted on the door body 201. Simultaneously, the positioning hole 41 on the reinforcing member 4 facilitates the connection and positioning of the first connecting member 2. This allows the door body 201 to be positioned and connected to the first connecting member 2 through the positioning hole 41 after the position of the first connecting member 2 relative to the first hinge body 1 is adjusted. This enables the adjustment of the position of the first connecting member 2 relative to the first hinge body 1, thereby adjusting the position of the door body 201 relative to the first hinge body 1.

[0046] In one embodiment, the hinge structure 100 further includes a first locking member 5, which is configured to fix the first connector 2 relative to the first hinge body 1.

[0047] In this embodiment, the first locking member 5 can be a nut, which can cooperate with the first connecting member 2 selected by the positioning pin and lock the first connecting member 2 to the first hinge body 1. After the first connecting member 2 passes through the first adjusting hole 111 and the positioning hole 41, the first locking member 5 can lock the first connecting member 2, the reinforcing member 4 and the connecting part 11.

[0048] Understandably, the first locking element 5 is designed so that the first connecting element 2 can be fixed relative to the reinforcing element 4 and the first hinge body 1 after adjustment, making the subsequent assembly and installation more reliable.

[0049] In one embodiment, the first connector 2 includes a protrusion 21 and a body portion 22, and the first locking member 5 clamps at least a portion of the body portion 22 between the first locking member 5 and the protrusion 21.

[0050] In this embodiment, the protrusion 21 is connected to the body part 22. The body part 22 can pass through the first adjustment hole 111 and the positioning hole 41. After adjustment, the protrusion 21 abuts against the connecting part 11 and is then connected to the body part 22 through the first locking member 5, so that the first locking member 5 abuts against the reinforcing member 4. At this time, the first locking member 5 clamps at least part of the body part 22 between the first locking member 5 and the protrusion 21.

[0051] Understandably, the first locking member 5 clamps at least part of the main body 22 between the first locking member 5 and the protrusion 21 to fix the first connecting member 2 relative to the connecting part 11 and the reinforcing member 4, ensuring that the connection is stable after the first connecting member 2 is adjusted.

[0052] Further integration Figure 6 As shown, in one embodiment, a second adjustment hole 12 is provided on the first hinge body 1. The second connector 3 can move within the second adjustment hole 12 along the second direction X, and the second connector 3 can move within the second adjustment hole 12 along the third direction Z.

[0053] In this embodiment, multiple second adjustment holes 12 may be provided, and each second adjustment hole 12 may have a certain space to allow the second connecting member 3 to move within the second adjustment hole 12 along the second direction X and the third direction Z, thereby adjusting the position of the second connecting member 3. The hinge structure 100 may also include a second locking member, which may be a nut or other component capable of fixing the second connecting member 3 relative to the first hinge body 1; no further restrictions are imposed here. After the second connecting member 3 is adjusted within the second adjustment hole 12, the second locking member fixes the second connecting member 3 relative to the first hinge body 1, so that the position of the vehicle body 301 relative to the first hinge body 1 in the second direction X and the third direction Z is adjustable, thereby adjusting the position of the door body 201 connected to the first hinge body 1 relative to the vehicle body 301.

[0054] It is understandable that the second connecting member 3 can move relative to the first hinge body 1 in the second direction X and the third direction Z by setting the second adjustment hole 12. Combined with the setting of the first adjustment hole 111 and the first connecting member 2, the door body 201 can be independently adjusted relative to the body body 301 in the first direction Y, the second direction X and the third direction Z.

[0055] In other embodiments, one end of the second hinge body 6 is connected to the door body 201, and the other end has a third adjustment hole 61. Multiple third adjustment holes 61 may be provided, and each hole 61 may have sufficient space to allow the third connecting member 7 to move within the third adjustment hole 61 along the second direction X and the third direction Z, thereby adjusting the position of the third connecting member 7. The hinge structure 100 may also include a third locking member, which may be a nut or other component capable of fixing the third connecting member 7 relative to the second hinge body 6; no further limitations are imposed here. After the third connecting member 7 is adjusted within the third adjustment hole 61, the third locking member fixes the third connecting member 7 relative to the second hinge body 6, allowing the position of the vehicle body 301 relative to the second hinge body 6 in the second direction X and the third direction Z to be adjustable, thereby adjusting the position of the door body 201 connected to the second hinge body 6 relative to the vehicle body 301.

[0056] It is understood that by opening a second adjustment hole 12 on the first hinge body 1 and a third adjustment hole 61 on the second hinge body 6, both the first hinge body 1 and the second hinge body 6 can adjust their positions relative to the vehicle body 301 in the second direction X and the third direction Z. The hinge structure 100 can be adjusted as a whole relative to the vehicle body 301, thereby adjusting the position of the door body 201 connected to the hinge structure 100 in the second direction X and the third direction Z.

[0057] This application embodiment also provides a door assembly 200, which is connected to the vehicle body 301, including the door body 201 and the hinge structure 100 as described above. One end of the hinge structure 100 is connected to the door body 201, and the other end is connected to the vehicle body 301.

[0058] It is understandable that the door assembly 200 with the aforementioned hinge structure 100 can be adjusted independently in the first direction Y, the second direction X, and the third direction Z during rough assembly of the hinge structure 100 with the door, making assembly easier.

[0059] This application embodiment also provides a vehicle 300, including a body body 301 and a door assembly 200 as described above. The door assembly 200 is connected to the body body 301, and the door body 201 is connected to the body body 301 through a hinge structure 100.

[0060] It is understandable that when installing the door of a vehicle 300 including the aforementioned door assembly 200, the position of the hinge structure 100 can be adjusted to make the door easier to install and adjust, thereby improving the efficiency of door installation and adjustment, and thus improving the production efficiency of the vehicle 300.

[0061] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
