Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a tailgate hinge structure, a tailgate and a vehicle. Background Art

[0002] The vehicle's tailgate, also known as the tailgate or rear door, is a body part located at the rear of the vehicle body that protects and covers the occupants or stored items and can be moved outward. The tailgate hinge is one of the important components that connects the vehicle's tailgate to the body. The vehicle has high connection strength requirements for the tailgate hinge.

[0003] In the related art, with the vehicle width direction as the Y direction and the vehicle length direction as the X direction, the tailgate hinge is usually connected to the tailgate through two connecting bolts in the Y direction or the X direction, and then the tailgate is connected to the body-in-white through the tailgate hinge.

[0004] However, in the above-mentioned related technologies, in order to achieve the required connection strength of the tailgate hinge structure, a relatively thick structure needs to be provided at the tailgate to ensure sufficient force-bearing area between the connecting bolts and the tailgate, resulting in a bloated and heavy structure at that part of the tailgate. Utility Model Content

[0005] In view of this, an embodiment of the present application provides a tailgate hinge structure, a tailgate and a vehicle. By changing the connecting components between the tailgate hinge and the vehicle tailgate, the dependence on the structural thickness of the tailgate connection is reduced and the connection strength is improved.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides a tailgate hinge structure, comprising: a body connecting portion connected to a body-in-white; a tailgate connecting portion, comprising a first structural plate and a second structural plate connected to a tailgate door body, the second structural plate extending along a plate surface of the first structural plate in a direction away from the first structural plate, a connecting assembly being provided on the second structural plate, the connecting assembly comprising a gap adjusting member, and when the second structural plate is assembled with the tailgate door body, the gap adjusting member abuts against the tailgate door body.

[0008] A tailgate hinge structure provided in an embodiment of the present application realizes the hinging of the body-in-white and the tailgate by setting a body connecting part to be connected to the body-in-white, and then connecting to the tailgate through a tailgate connecting part hinged to the body connecting part, thereby realizing the hinging of the body-in-white and the tailgate, and at the same time, the tailgate connecting part includes a first structural plate and a second structural plate, and the second structural plate extends from the first structural plate at a certain angle, thereby providing two mounting surfaces abutting the tailgate and being respectively connected to the tailgate by fasteners, and the two intersecting mounting surfaces provide a multi-angle reliable force transmission structure for the connection between the tailgate connecting part and the tailgate, thereby making the connection between the tailgate hinge structure and the tailgate more stable and reliable, and at the same time reducing the dependence on the structural thickness of the tailgate connection, thereby reducing the weight of the tailgate and thus reducing the weight of the entire vehicle, thereby meeting the lightweight requirements of the vehicle.

[0009] In a possible implementation of the present application, the connecting assembly also includes a mounting hole and a threaded connecting piece, the gap adjustment piece is an adjusting nut installed in the mounting hole, the adjusting nut slides with the mounting hole along the axial direction of the mounting hole, and in the assembled state, the threaded connecting piece is threadedly connected to the adjusting nut, and the adjusting nut is pressed against the back door body.

[0010] In a possible implementation of the present application, the adjusting nut extends out of the mounting hole toward one end of the tailgate body and forms an abutting flange, and the abutting flange is arranged around the circumference of the adjusting nut.

[0011] In a possible implementation of the present application, the mounting hole is a non-circular hole, and the outer surface of the adjusting nut is adapted to the mounting hole.

[0012] In a possible implementation of the present application, a boss structure is provided on the second structural plate, and the mounting hole is provided on the boss structure.

[0013] In a possible implementation of the present application, a limiting portion is provided in the mounting hole to prevent the adjusting nut from completely falling out of the mounting hole.

[0014] In a possible implementation of the present application, the mounting hole is a countersunk hole, a threaded hole is provided through the bottom of the mounting hole, the threaded hole is coaxially arranged with the mounting hole, and the thread of the threaded hole is arranged in the same direction as the thread of the adjusting nut.

[0015] In a possible implementation of the present application, the first structural plate is perpendicular to a plane where the vehicle body connecting portion is connected to the body-in-white, and the second structural plate is disposed perpendicular to the first structural plate.

[0016] In a second aspect, an embodiment of the present application provides a back door, comprising: a back door body having a first mounting surface and a second mounting surface; the above-mentioned back door hinge structure, wherein the first structural plate is connected to the first mounting surface, and the second structural plate is connected to the second mounting surface.

[0017] A tailgate provided in an embodiment of the present application is connected to the body-in-white through the above-mentioned tailgate hinge structure. Since the tailgate is provided with a first mounting surface and a second mounting surface, which are respectively connected to the first structural plate and the second structural plate intersecting the tailgate hinge, forces in multiple directions are transmitted between the tailgate and the tailgate hinge structure through surface contact, rather than the traditional hinges which transmit forces through a combination of surface contact and point positioning of fasteners. This makes the connection have higher structural strength and the structure more stable. At the same time, since the structural strength is greatly improved, there is no need to increase the thickness of the tailgate to increase the contact area between the fasteners and the tailgate, thereby improving the strength of the connection structure, so that the tailgate design is thinner and lighter, meeting the lightweight requirements of the vehicle.

[0018] In a third aspect, an embodiment of the present application provides a vehicle, comprising: a body in white; the above-mentioned tailgate, wherein the door body is hinged to the tailgate hinge structure, and the tailgate hinge is hinged to the body in white.

[0019] A vehicle provided in an embodiment of the present application adopts the above-mentioned tailgate, and the tailgate is connected to the body-in-white through a tailgate hinge structure. Since the force is transmitted between the tailgate hinge and the tailgate through two intersecting first mounting surfaces and second mounting surfaces, compared with the traditional hinge connection method, the structure has higher strength and more stable structure, and the design thickness of the tailgate can be thinner, thereby achieving a weight reduction effect. While meeting the lightweight requirements of the vehicle, the connection stability of the tailgate and the body-in-white is also ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0030] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0031] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0032] The embodiment of the present application provides a vehicle. It should be noted that the vehicle in the present application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other vehicle types. Generally, a vehicle is provided with a body-in-white and a back door. The back door is provided at the rear of the body-in-white and is hinged to the body-in-white to protect the occupants or the objects in the vehicle.

[0033] It should be noted that in the embodiment of the present application, the type and size of the body-in-white and the tailgate are not limited. The body-in-white door and the tailgate are hinged to each other through a tailgate hinge structure so that the tailgate can be opened by rotating from the body-in-white.

[0034] On this basis, refer to Figure 4 The embodiment of the present application also provides a back door, which has a first mounting surface and a second mounting surface, the planes where the first mounting surface and the second mounting surface are located intersect, and the back door hinge structure is fixed to the back door by connecting to the first mounting surface and the second mounting surface respectively.

[0035] It should be noted that in the embodiments of the present application, the angle between the first mounting surface and the second mounting surface, the specific positions and forms of the first mounting surface and the second mounting surface are not limited. Exemplarily, the first mounting surface and the second mounting surface are two planes intersecting at the edges of the back door, and the first mounting surface is arranged perpendicular to the second mounting surface.

[0036] In the present embodiment, the tailgate is connected to the body-in-white through the above-mentioned tailgate hinge structure. Since the tailgate is provided with a first mounting surface and a second mounting surface which are respectively connected to the tailgate hinge, forces in multiple directions are transmitted between the tailgate and the tailgate hinge structure through surface contact, rather than the traditional hinge which transmits forces through a combination of surface contact and point positioning of fasteners. This makes the connection have higher structural strength and the structure more stable. At the same time, since the structural strength is greatly improved, there is no need to increase the thickness of the tailgate to increase the contact area between the fastener and the tailgate, thereby improving the strength of the connection structure, so that the tailgate design is thinner and lighter, meeting the lightweight requirements of the vehicle.

[0037] On this basis, refer to Figure 1 and Figure 2 Furthermore, the embodiment of the present application also provides a tailgate, a tailgate hinge structure, including a body connecting part 100, connected to the body-in-white; a tailgate connecting part 200, including a first structural plate 201 and a second structural plate 202 connected to the tailgate door body 400, the second structural plate 202 extends along the plate surface of the first structural plate 201 in a direction away from the first structural plate 201, and a connecting component 300 is provided on the second structural plate 202, the connecting component 300 includes a gap adjusting member, and when the second structural plate 202 and the tailgate door body 400 are assembled, the gap adjusting member abuts against the tailgate door body 400.

[0038] In this embodiment, the body-in-white and the tailgate are hinged by providing a body connection part 100 connected to the body-in-white, and then connecting the tailgate through a tailgate connection part 200 hinged to the body connection part 100. At the same time, the tailgate connection part 200 includes a first structural plate 201 and a second structural plate 202. The second structural plate 202 extends from the first structural plate 201 at a certain angle, thereby providing two mounting surfaces abutting the tailgate and being respectively connected to the tailgate by fasteners. The two intersecting mounting surfaces provide a multi-angle reliable force transmission structure for the connection between the tailgate connection part 200 and the tailgate, thereby making the connection between the tailgate hinge structure and the tailgate more stable and reliable, and at the same time reducing the dependence on the thickness of the structure at the tailgate connection, thereby reducing the weight of the tailgate and reducing the weight of the entire vehicle, thereby meeting the lightweight requirements of the vehicle.

[0039] In the above embodiment, it should be noted that the above embodiment does not limit the relative position relationship between the first structural plate 201 and the second structural plate 202 of the back door body 400. The first structural plate 201 can be perpendicular to the back door panel or at a certain angle to the back door panel. The first structural plate 201 is provided with a connecting hole 2011 for fasteners to pass through. The angle between the second structural plate 202 and the first structural plate 201 can be an acute angle, a right angle or an obtuse angle.

[0040] In addition, it should be noted that the embodiment of the present application does not limit the specific form of the vehicle body connection portion 100, and the vehicle body connection portion 100 can be installed on the white vehicle body by fasteners or other connection methods.

[0041] Further, in some embodiments of the present application, please refer to Figure 2 The connection assembly 300 also includes a mounting hole 301 and a threaded connection piece 303. The gap adjustment piece is an adjustment nut 302 installed in the mounting hole 301. The adjustment nut 302 slides with the mounting hole 301 along the axial direction of the mounting hole 301. In the assembled state, the threaded connection piece 303 is threadedly connected to the adjustment nut 302, and the adjustment nut 302 is pressed against the back door body 400.

[0042] Specifically, the threaded connector 303 may be a general fastener with threads such as a screw, a bolt, a stud, etc. In some embodiments not shown, it may also be a special connector with threads specially designed for the corresponding vehicle model.

[0043] In this embodiment, since the tailgate hinge structure is connected to the tailgate through two intersecting first structural plates 201 and second structural plates 202 respectively, after the first structural plate 201 and the tailgate are fixed by fasteners, the relative position between the second structural plate 202 and the tailgate is also determined. However, since there is a certain tolerance between the body-in-white and the tailgate, there is a certain gap between the second structural plate 202 and the mounting surface of the tailgate during the actual assembly process. In this embodiment, an adjusting nut 302 is provided as a threaded connector 303, and the adjusting nut 302 is made to slide circumferentially in the mounting hole 301. During the actual assembly process, when the threaded connector 303 passes through the tailgate and extends into the adjusting nut 302, the adjusting nut 302 is driven by the rotation of the threaded connector 303, slides outward from the mounting hole 301 and presses against the tailgate direction, thereby making up the gap through the lifting and lowering of the adjusting nut 302, so that the second structural plate 202 can be stably and reliably connected to the tailgate.

[0044] Further, in some embodiments of the present application, please refer to Figure 2 The adjusting nut 302 extends out of the mounting hole 301 toward one end of the back door body 400 and forms an abutting flange 3021 , which is arranged around the circumference of the adjusting nut 302 .

[0045] Specifically, the abutting flange 3021 is arranged on the circumference of the adjusting nut 302 and extends to the side away from the axis of the adjusting nut 302. The embodiment of the present application does not limit the specific size and shape of the abutting flange 3021, and the abutting position of the flange and the tailgate body 400 can be adapted.

[0046] In this embodiment, by providing an abutting flange 3021 at the end of the adjusting nut 302, the contact area between the adjusting nut 302 and the back door in the assembled state is greatly increased, which plays the role of a "gasket" structure, making the connection between the adjusting nut 302 and the back door more stable and stronger.

[0047] Furthermore, in some embodiments of the present application, the mounting hole 301 is a non-circular hole, and the outer surface of the adjusting nut 302 is adapted to the mounting hole 301 .

[0048] In this embodiment, by setting the mounting hole 301 as a non-circular hole and making the outer surface of the adjusting nut 302 adapt to the mounting hole 301, when the threaded connection 303 extends into the adjusting nut 302, the rotation of the adjusting nut 302 is restricted by the non-circular mounting hole 301, thereby avoiding the situation where the adjusting nut 302 rotates in the same direction as the threaded connection 303 and cannot be tightly connected with the back door, making the assembly process smoother and more convenient.

[0049] Further, in some embodiments of the present application, please refer to Figure 2 and Figure 3 A boss structure 2021 is provided on the second structural plate 202 , and the mounting hole 301 is provided on the boss structure 2021 .

[0050] Specifically, on the second mounting surface of the back door, a receiving groove 401 is provided at a position adapted to the boss structure 2021. In the assembled state, the raised portion of the boss structure 2021 toward the back door extends into the receiving groove 401, which is beneficial to the pre-positioning of the parts assembly and can cover the threaded connection 303, making the back door more beautiful.

[0051] In this embodiment, a boss structure 2021 is provided on the second structural plate 202, the second structural plate 202 is locally thickened in a targeted manner, and the mounting hole 301 is provided on the boss structure 2021, thereby providing sufficient space for accommodating the adjusting nut 302 and improving the strength of the connection between the second structural plate 202 and the tailgate. At the same time, the threaded connection 303 and the second structural plate 202 have sufficient connection area and can withstand higher loads. In addition, the tailgate hinge structure itself is relatively small in size, and the weight of the local thickening can be ignored for the vehicle as a whole.

[0052] Further, in some embodiments of the present application, please refer to Figure 2 A limiting portion 3012 is provided in the mounting hole 301 to prevent the adjusting nut 302 from completely escaping from the mounting hole 301 .

[0053] It should be noted that the embodiment of the present application does not limit the specific form of the limiting portion 3012, and it is sufficient to prevent the adjusting nut 302 from escaping from the mounting hole 301. For example, the limiting portion 3012 can be a tightening portion at the orifice of the mounting hole 301 that reduces the diameter of the orifice, and cooperates with the adjusting nut 302 to slightly increase the diameter toward the bottom of the mounting hole 301, thereby preventing the adjusting nut 302 from escaping. In some embodiments not shown, the limiting portion 3012 can also be a limiting block arranged on the wall of the mounting hole 301, which cooperates with the limiting groove on the side wall of the adjusting nut 302. When the adjusting nut 302 is about to detach from the mounting hole 301, the limiting block abuts against the wall of the limiting groove and prevents the adjusting nut 302 from continuing to escaping. The specific forms of the above-mentioned limiting portion 3012 are all within the protection scope of the present embodiment.

[0054] In this embodiment, the limiting portion 3012 is provided to prevent the adjusting nut 302 from escaping from the mounting hole 301, thereby preventing the connection between the second structural plate 202 and the back door from failing, thereby improving the reliability of the connection structure.

[0055] Further, in some embodiments of the present application, please refer to Figure 2 The mounting hole 301 is a countersunk hole, and a threaded hole 3011 is provided at the bottom of the mounting hole 301 . The threaded hole 3011 is coaxially arranged with the mounting hole 301 , and the thread of the threaded hole 3011 is arranged in the same direction as the thread of the adjusting nut 302 .

[0056] In this embodiment, the mounting hole 301 is configured as a countersunk hole, and a threaded hole 3011 is coaxially configured at the bottom of the countersunk hole, so that the threaded connector 303 can extend into the threaded hole 3011 after passing through the nut and be directly connected to the back door. The threaded connector 303 not only fixes the second structural plate 202 and the back door by being threadedly connected to the adjusting nut 302, but is also directly threadedly connected to the second structural plate 202 on the premise that the adjusting nut 302 is pressed against the back door, thereby further improving the reliability of the connection, improving the structural strength, and effectively preventing the structure from loosening.

[0057] Further, in some embodiments of the present application, please refer to Figure 3 and Figure 4 The first structural plate 201 is perpendicular to the plane where the vehicle body connecting portion 100 is connected to the body-in-white, and the second structural plate 202 is arranged perpendicular to the first structural plate 201 .

[0058] In the present embodiment, the first structural plate 201 is perpendicular to the plane of the connection with the body-in-white, and the second structural plate 202 is arranged perpendicular to the first structural plate 201, so that the first mounting surface and the second mounting surface on the tailgate that match the first structural plate 201 and the second structural plate 202 are orthogonal, and the connecting piece connecting the first structural plate 201 and the tailgate is perpendicular to the threaded connecting piece 303 on the second structural plate 202, and the tailgate is fixed from two perpendicular directions respectively, so that the connecting structure has good stability and structural strength.

[0059] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
