Description

Technical Field

[0001] This application relates to the field of vehicle door adjustment, and more particularly to a positioning structure, a vehicle door assembly, and a vehicle. Background Technology

[0002] Currently, some vehicles use swing-open doors. The hinge structure that connects the door to the vehicle body makes it difficult to install, adjust, and reinstall the door during the overall vehicle installation process, and the installation accuracy is hard to guarantee. Utility Model Content

[0003] To address the difficulties in assembling and reassembling swing-opening car doors, embodiments of this application provide a positioning structure that is easy to adjust and ensures accuracy, as well as a car door assembly and a vehicle.

[0004] This application provides a positioning structure connected to a hinge structure. The positioning structure includes an adjustment component and a first positioning member. The hinge structure has a first adjustment hole, and the adjustment component is movably connected to the hinge structure. The first positioning member is configured to be connected to a door body and has a second adjustment hole. The adjustment component can move along a first direction in one of the first adjustment hole and the second adjustment hole, and along a second direction in the other. The first direction and the second direction intersect.

[0005] It is understandable that by opening the first adjustment hole and the second adjustment hole on the hinge structure and the first positioning member, the adjustment component can move along the first direction and the second direction in the first adjustment hole and the second adjustment hole, so that the position of the first positioning member fixedly connected to the adjustment component after the adjustment is completed is adjusted, thereby enabling the door body connected to the hinge structure through the first positioning member to be adjusted and ensuring the installation accuracy.

[0006] In one embodiment, the positioning structure further includes a fixing member movably connected to the adjusting component. Based on the movement of the fixing member relative to the adjusting component, the fixing member can fix the adjusting component relative to the first positioning member in a first fixed state or release the first fixed state.

[0007] In one embodiment, the adjustment assembly includes a first adjustment member and a second adjustment member. The first adjustment member passes through the first adjustment hole and is movable within the first adjustment hole. The second adjustment member is connected to the first adjustment member. At least one of the first adjustment member and the second adjustment member is movable within the second adjustment hole.

[0008] In one embodiment, the second adjusting member is movably connected to the first adjusting member. Based on the movement of the second adjusting member relative to the first adjusting member, the second adjusting member can fix the first adjusting member relative to the hinge structure in a second fixed state or release the second fixed state.

[0009] In one embodiment, the first adjusting member passes through the second adjusting hole, the fixing member is connected to the first adjusting member, and along a third direction, the two sides of the first positioning member abut against the hinge structure and the fixing member respectively, and the third direction intersects with the first direction and the second direction.

[0010] In one embodiment, the second adjusting member has a connecting hole, and the fixing member can at least partially extend into the connecting hole, and the portion of the fixing member extending into the connecting hole is connected to the second adjusting member.

[0011] In one embodiment, the second adjusting member includes a limiting portion located outside the second adjusting hole along a third direction. The first positioning member abuts against the fixing member and the limiting portion on both sides to restrict displacement in the third direction, which intersects the first direction and the second direction.

[0012] This application embodiment also provides a door assembly connected to the vehicle body, including the positioning structure, sub-positioning structure, door body and hinge structure as described above. One side of the hinge structure is connected to the door body through the positioning structure and the sub-positioning structure, and the other side of the hinge structure is connected to the vehicle body.

[0013] Understandably, a door assembly with the positioning structure described above is easier to adjust during installation and ensures accuracy. It also facilitates reassembly; during disassembly, the hinge structure does not need to be disassembled, only the door body needs to be removed and reassembled. During reassembly, the first positioning component enables precise positioning and installation, reducing the difficulty of reassembly.

[0014] In one embodiment, the secondary positioning structure includes a second positioning member and a third adjusting member. The hinge structure has a third adjusting hole. The third adjusting member passes through the third adjusting hole and can move along the second direction in the third adjusting hole. The second positioning member is connected to the third adjusting member.

[0015] This application embodiment also provides a vehicle, including a door assembly and a body body as described above, wherein the door assembly is connected to the body body via the hinge structure.

[0016] Understandably, vehicles equipped with the aforementioned door assembly require higher precision during door body installation and are easier and simpler to reinstall, thus improving door installation efficiency and accuracy. Attached Figure Description

[0030] like Figures 1 to 3 As shown, this application embodiment provides a positioning structure 100 connected to a hinge structure 200. The positioning structure 100 includes an adjustment component 1 and a first positioning member 2. A first adjustment hole 201 is provided on the hinge structure 200, and the adjustment component 1 is movably connected to the hinge structure 200. The first positioning member 2 is configured to be connected to the door body 301, and a second adjustment hole 21 is provided on the first positioning member 2.

[0031] For ease of reading, this application introduces a first direction X, a second direction Z, and a third direction Y to describe the embodiments of this application. The first direction X, the second direction Z, and the third direction Y can be three non-parallel straight lines in space; further, the first direction X, the second direction Z, and the third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction X is described as the X-axis direction of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the three-dimensional coordinate system.

[0032] The adjustment component 1 can move along a first direction X in one of the first adjustment hole 201 and the second adjustment hole 21, and along a second direction Z in the other.

[0033] In this embodiment, the adjusting component 1 moves along the first direction X in the first adjusting hole 201 and along the second direction Z in the second adjusting hole 21. Specifically, along the first direction X, the width of the first adjusting hole 201 is greater than the outer diameter of the adjusting component 1, so that the adjusting component 1 can move along the first direction X within the first adjusting hole 201. When the adjusting component 1 moves in the first adjusting hole 201, its two sides along the second direction Z abut against the hole wall of the first adjusting hole 201, thereby limiting its displacement along the second direction Z within the first adjusting hole 201 and ensuring the reliability of its movement along the first direction X.

[0034] Along the second direction Z, the width of the second adjusting hole 21 is greater than the outer diameter of the adjusting component 1, so that the adjusting component 1 can move along the second direction Z within the second adjusting hole 21. When the adjusting component 1 moves within the second adjusting hole 21, its two sides along the first direction X abut against the hole wall of the second adjusting hole 21, thereby restricting its displacement along the first direction X within the second adjusting hole 21 and ensuring the reliability of its movement along the second direction Z. The adjusting component 1 can be a bolt assembly to be fixedly connected to the hinge structure 200 after adjustment, ensuring a firm and reliable position after adjustment. Other adjustable and fixable components can also be used for the adjusting component 1; no further restrictions are imposed here.

[0035] After the adjusting component 1 moves along the first direction X through the first adjusting hole 201 and completes the adjustment, it is fixedly connected to the hinge structure 200. Then, the adjusting component 1 is at least partially inserted into the second adjusting hole 21, and the displacement of the first positioning member 2 in the second direction Z is moved, thus allowing the adjusting component 1 to move within the second adjusting hole 21. After the position of the first positioning member 2 is adjusted, it is fixedly connected to the hinge structure 200 and connected to the vehicle door. This completes the adjustment of the position of the first positioning member 2 in the first direction X and the second direction Z, making the connected vehicle door easier to install and ensuring installation accuracy. The first positioning member 2 can be a positioning pin, used for subsequent connection to the vehicle door and for positioning.

[0036] It is understood that by opening the first adjustment hole 201 and the second adjustment hole 21 on the hinge structure 200 and the first positioning member 2, the adjustment component 1 can move along the first direction X and the second direction Z in the first adjustment hole 201 and the second adjustment hole 21, thereby adjusting the position of the first positioning member 2 which is fixedly connected to the adjustment component 1 after adjustment, and thus enabling the door body 301 connected to the hinge structure 200 through the first positioning member 2 to be adjusted and ensuring installation accuracy.

[0037] In one embodiment, the positioning structure 100 further includes a fixing member 3, which is movably connected to the adjustment component 1. Based on the movement of the fixing member 3 relative to the adjustment component 1, the fixing member 3 can fix the adjustment component 1 relative to the first positioning member 2 and put it in a first fixed state or release the first fixed state.

[0038] In this embodiment, when in the first fixed state, the first positioning member 2, the adjusting component 1, and the hinge structure 200 are all relatively fixed. When the adjusting component 1 has a threaded hole, the fixing member 3 can be a bolt for movable connection with the adjusting component 1. When it is necessary for the first positioning member 2 and the adjusting component 1 to be relatively fixed in the first fixed state, tightening the fixing member 3 with the selected bolt will achieve this. When it is necessary to release the first fixed state between the adjusting component 1 and the first positioning member 2, the fixing member 3 with the selected bolt can be loosened to release the first fixed state.

[0039] Further integration Figure 4 and Figure 5 As shown, in another embodiment, the adjusting component 1 may be provided with bolts, and the fixing member 3 may be a nut. The fixing member 3 and the adjusting component 1 are connected by threads, so that the adjusting component 1 and the first positioning member 2 can be in a first fixed state or released from the first fixed state.

[0040] It is understandable that after adjustment, the adjustment component 1 and the first positioning component 2 can be fixed by the fixing component 3, thereby ensuring that the first positioning component 2 is accurately and precisely connected to the door.

[0041] In one embodiment, the adjustment component 1 includes a first adjustment member 11 and a second adjustment member 12. The first adjustment member 11 passes through a first adjustment hole 201 and can move within the first adjustment hole 201. The second adjustment member 12 is connected to the first adjustment member 11. At least one of the first adjustment member 11 and the second adjustment member 12 can move within the second adjustment hole 21.

[0042] In this embodiment, the first adjusting member 11 can be a bolt, and the second adjusting member 12 can be a pin sleeve with a threaded hole, so that the first adjusting member 11 and the second adjusting member 12 can be detachably connected. After the first adjusting member 11 is adjusted in the first adjusting hole 201, it is connected and fixed relative to the second adjusting member 12, thereby completing the installation of the adjusting assembly 1. After installation, at least one of the first adjusting member 11 and the second adjusting member 12 is moved in the second adjusting hole 21 for secondary adjustment.

[0043] It is understandable that by setting the first adjusting member 11 and the second adjusting member 12, the first adjusting member 11 can move within the first adjusting hole 201, thereby achieving the adjustment of the adjusting component 1. Furthermore, the movable first positioning member 2 moves relative to the adjusting component 1 through the second adjusting hole 21, further adjusting the position of the first positioning member 2.

[0044] In one embodiment, the second adjusting member 12 is movably connected to the first adjusting member 11. Based on the movement of the second adjusting member 12 relative to the first adjusting member 11, the second adjusting member 12 can fix the first adjusting member 11 relative to the hinge structure 200 to a second fixed state or release the second fixed state.

[0045] In this embodiment, similarly, the first adjusting member 11 can be a bolt, and the second adjusting member 12 can be a pin sleeve with a threaded hole, so that the two can be movably connected. When the first adjusting member 11 is a bolt, along the third direction Y, the nut and screw of the first adjusting member 11 can be located on both sides of the hinge structure 200, wherein the screw is on the same side as the second adjusting member 12, and the nut can abut against the hinge structure 200. After the first adjusting member 11 has moved within the first adjusting hole 201, when the second adjusting member 12 is connected to the first adjusting member 11, the nut of the first adjusting member 11 and the second adjusting member 12 clamp the hinge structure 200 from both sides, thereby achieving relative fixation between the first adjusting member 11, the second adjusting member 12, and the hinge structure 200, that is, in the second fixed state, thus completing the installation of the adjusting assembly 1. Then, the connection between the first adjusting member 11 and the second adjusting member 12 is released by threading, thereby releasing the second fixed state.

[0046] It is understandable that, based on the movement of the second adjusting member 12 relative to the first adjusting member 11, the adjusting component 1 can be fixed relative to the hinge structure 200 after adjustment, which facilitates subsequent installation.

[0047] In one embodiment, the first adjusting member 11 passes through the second adjusting hole 21, and the fixing member 3 is connected to the first adjusting member 11. Along the third direction Y, the two sides of the first positioning member 2 abut against the hinge structure 200 and the fixing member 3 respectively.

[0048] For details in this embodiment, please refer to [link / reference]. Figure 5 The first adjusting member 11 can be a bolt with a relatively long screw, in which case the fixing member 3 can be a nut. After the second adjusting member 12 is connected and fixed to the first adjusting member 11, the first adjusting member 11 can move and adjust in the second adjusting hole 21. After adjustment, a portion of the first adjusting member 11 remains outside the second adjusting hole 21 for connection with the fixing member 3, thereby causing the first positioning member 2 to abut against the hinge structure 200 and the fixing member 3 on both sides along the third direction Y, thus allowing the first positioning member 2 to be fixed relative to the hinge structure 200 and in a first fixed state.

[0049] Understandably, when the portion of the first adjusting member 11 on the side of the first positioning member 2 is longer, adjusting the position of the first adjusting member 11 can directly adjust this portion, making it easier for the operator to operate. Furthermore, during door installation, it is not necessary to open and close the door separately to adjust the positions of the first adjusting member 11 and the first positioning member 2; both can be adjusted even with the door closed, making the overall process more convenient. Additionally, if the first adjusting member 11 can pass through the second adjusting hole 21, the fixing member 3 can be secured with a nut, making the fixation more convenient and secure.

[0050] In one embodiment, the second adjusting member 12 has a connecting hole 120, and the fixing member 3 can at least partially extend into the connecting hole 120, and the portion of the fixing member 3 extending into the connecting hole 120 is connected to the second adjusting member 12.

[0051] For details in this embodiment, please refer to [link / reference]. Figure 3 At this point, the first adjusting member 11 can be a bolt, but the threaded portion of the bolt is too short to pass through the second adjusting hole 21; only a portion extends into the connecting hole 120 of the second adjusting member 12. The connecting hole 120 is a threaded hole to allow the first adjusting member 11 to connect with the second adjusting member 12. The second adjusting member 12 can then move within the second adjusting hole 21.

[0052] In one embodiment, the second adjusting member 12 includes a limiting part 121 located outside the second adjusting hole 21 along the third direction Y. The first positioning member 2 abuts against the fixing member 3 and the limiting part 121 on both sides to limit the displacement in the third direction Y.

[0053] For details in this embodiment, please refer to [link / reference]. Figure 3The first adjusting member 11 can be a bolt, and the bolt's threaded portion is relatively short. When the second adjusting member 12 is connected to the first adjusting member 11, the first adjusting member 11 is relatively fixed to the hinge structure 200 in a second fixed state. At this time, the limiting part 121 abuts against the hinge structure 200 on one side along the third direction Y. When the fixing member 3 fixes the adjusting component 1 to the first positioning member 2 in a first fixed state, the first positioning member 2 abuts against the fixing member 3 and the limiting part 121 on both sides, thus limiting its displacement in the third direction Y. The first positioning member 2 also has a through hole 22, which communicates with the second adjusting hole 21. The diameter of the through hole 22 is smaller than the diameter of the second adjusting hole 21, so as to form a stepped surface between the through hole 22 and the second adjusting hole 21. Along the second direction Z, the outer diameter of the second adjusting member 12 is smaller than the length of the second adjusting hole 21, and the outer diameter of the second adjusting member 12 is larger than the diameter of the through hole 22. When the first positioning member 2 is in the first fixed state, the second adjusting member 12 abuts against the stepped surface on the side away from the first adjusting member 11 in the third direction Y. In this way, the first positioning member 2 also restricts the displacement of the second adjusting member 12 in the third direction Y. When the fixing member 3 is fixed with bolts, the screw of the fixing member 3 can pass through the through hole 22 and extend into the threaded hole opened in the second adjusting member 12 for connection by threads.

[0054] Furthermore, the nut of the fixing member 3 is located outside the first positioning member 2, and the nut of the fixing member 3 presses the first positioning member 2 against the second adjusting member 12 to clamp the first positioning member 2 between the fixing member 3 and the second adjusting member 12. The second adjusting member 12 is relatively fixed to the hinge structure 200 through its connection with the first adjusting member 11. The fixing member 3 is also connected to the second adjusting member 12, thereby achieving relative fixation between the second adjusting member 12, the first adjusting member 11, the first positioning member 2, the fixing member 3, and the hinge structure 200.

[0055] Specifically, the outer diameter of the screw of the fastener 3 is smaller than the outer diameter of the through hole 22, so that the screw of the fastener 3 can move in the second direction Z within the through hole 22.

[0056] It is understandable that when the first positioning member 2 is in the first fixed state by setting the limiting part 121, the displacement of the first positioning member 2 in the third direction Y is restricted, and the overall structure is firm and reliable.

[0057] like Figures 6 to 8 As shown, this application embodiment also provides a door assembly 300, which is connected to the vehicle body 401, including the positioning structure 100, the sub-positioning structure 302, the door body 301 and the hinge structure 200 as described above. One side of the hinge structure 200 is connected to the door body 301 through the positioning structure 100 and the sub-positioning structure 302, and the other side of the hinge structure 200 is connected to the vehicle body 401.

[0058] In this embodiment, the positioning structure 100 and the secondary positioning structure 302 are connected to the hinge structure 200, and the door body 301 is positioned and connected through the positioning structure 100 and the secondary positioning structure 302. The other side of the hinge structure 200 is connected to the vehicle body 401, thus enabling the door to be opened and closed through the hinge structure 200.

[0059] Understandably, the door assembly 300 with the aforementioned positioning structure 100 is easy to adjust during installation and ensures accuracy. It also facilitates reassembly. During disassembly, there is no need to disassemble the hinge structure 200; only the door body 301 needs to be disassembled and assembled. During reassembly, precise positioning and installation can be achieved through the first positioning component 2, reducing the difficulty of reassembly.

[0060] In one embodiment, the sub-positioning structure 302 includes a second positioning member 3021 and a third adjusting member 3022. The hinge structure 200 has a third adjusting hole 202. The third adjusting member 3022 passes through the third adjusting hole 202 and can move in the third adjusting hole 202 along the second direction Z. The second positioning member 3021 is connected to the third adjusting member 3022.

[0061] In this embodiment, the third adjusting member 3022 may be a bolt with an elliptical pin anti-rotation structure. The nut portion is located on one side of the hinge structure 200 in the third direction Y, and the screw portion passes through the third adjusting hole 202 on the other side of the hinge structure 200 in the third direction Y. Part of the screw can move within the third adjusting hole 202 along the second direction Z. The second positioning member 3021 may be a positioning pin, which may have threads for threaded connection with the selected screw in the third adjusting member 3022. After the second positioning member 3021 and the third adjusting member 3022 are connected, the side of the second positioning member 3021 along the third direction Y abuts against the hinge structure 200 to further ensure a firm and reliable connection between the sub-positioning structure 302 and the hinge structure 200. The door body 301 is positioned and connected to the hinge structure 200 via the second positioning member 3021.

[0062] It is understandable that the secondary positioning structure 302 is adjustable only along the second direction Z. Therefore, the third adjustment hole 202 opened on the hinge structure 200 allows the third adjustment member 3022 to move within it along the second direction Z for adjustment. After adjustment, the connection between the secondary positioning structure 302 and the hinge structure 200 is firm and reliable.

[0063] Further integration Figure 9 As shown, this application embodiment also provides a vehicle 400, including the door assembly 300 and the vehicle body 401 as described above, wherein the door assembly 300 is connected to the vehicle body 401 via a hinge structure 200.

[0064] It is understandable that vehicles 400 equipped with the aforementioned door assembly 300 have higher precision when installing the door body 301, and are more convenient and simpler to reinstall, thus improving the efficiency and precision of door installation.

[0065] 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.
