[0038] The present application embodiment provides a back door hinge structure, referring to the attached Figure 1-4 ,include:
[0039] A first hinge component 1, the first hinge component 1 comprises a first mounting plate 2 and a ball and socket component 3 connected to each other; a spherical cavity 301 is provided inside the ball and socket component 3, and an open groove 302 is provided on one side of the ball and socket component 3, and a groove direction of the open groove 302 is extended along the circumferential direction of the ball and socket component 3;
[0040] The second hinge component 4 includes a second mounting plate 5 and a ball head component 6 connected to each other; the ball head component 6 is movably connected in the spherical cavity 301, the second mounting plate 5 extends out of the ball socket component 3 through the opening groove 302, and the second mounting plate 5 can slide along the groove direction of the opening groove 302.
[0041] The back door hinge structure provided in the embodiment of the present application utilizes the ball socket 3 and the ball head 6 to cooperate with each other to realize the spherical connection between the first hinge 1 and the second hinge 4. On the basis of the spherical connection, the second hinge 4 can rotate around multiple axes relative to the first hinge 1, reducing the influence of the back door hinge posture on the flatness of the mounting surface of the vehicle body and the back door, thereby reducing the difficulty of adjusting the back door, and achieving the purpose of facilitating the posture control of the back door relative to the vehicle body. It can be understood that since the traditional back door hinge can only rotate around a single axis, the flatness of the mounting surface of the back door hinge, the back door and the vehicle body will be limited; during the fine adjustment of the back door, the XYZ directions of the back door and the vehicle body will affect each other, resulting in an increase in the difficulty of adjusting the back door, thereby affecting the back door posture. The embodiment of the present application adopts a spherical connection, so that the installation of the first hinge and the second hinge with the back door and the vehicle body can adapt to any mounting surface angle, which greatly reduces the design requirements of the back door hinge structure. At the same time, since the tailgate hinge structure is not affected by the flatness of the mounting surface, the deviation is absorbed by the connection between the ball socket component 3 and the ball head component 6, thereby reducing the precision requirements for components.
[0042] At the same time, an open groove 302 is provided on one side of the ball socket 3, and the groove direction of the open groove 302 extends along the circumferential direction of the ball socket 3; when the tailgate is opened or closed between the vehicle body, the second mounting plate 5 slides along the groove direction of its open groove 302.
[0043] It should be noted that, in the embodiment of the present application, the first mounting plate 2 is used to connect with the vehicle body, and the second mounting plate 5 is used to connect with the back door; or, the first mounting plate 2 is used to connect with the back door, and the second mounting plate 5 is used to connect with the vehicle body. In this way, combined with the introduction of the background technology, when the first mounting plate 2 is used to connect with the vehicle body, and the second mounting plate 5 is used to connect with the back door, the first hinge member 1 to which the first mounting plate 2 belongs is a female hinge, and the second hinge member 4 to which the second mounting plate 5 belongs is a male hinge; when the first mounting plate 2 is used to connect with the back door, and the second mounting plate 5 is used to connect with the vehicle body, the first hinge member 1 to which the first mounting plate 2 belongs is a male hinge, and the second hinge member 4 to which the second mounting plate 5 belongs is a female hinge. It can be seen that the arrangement scheme of the ball socket member 3 and the ball head member 6 in the female hinge and the male hinge in the embodiment of the present application can be swapped, and the present application does not impose specific restrictions on it. For the convenience of description, the following uses the first mounting plate 2 to connect with the vehicle body, and the second mounting plate 5 to connect with the back door for description.
[0044] In addition, it should be noted that in the embodiments of the present application, Figure 5-8 The first mounting plate 2 is provided with at least two first mounting holes 201, and the first mounting holes 201 are used for the first fixing bolts (not shown in the drawings) to pass through; in this way, the first fixing bolts pass through the first mounting holes 201 and are fixedly connected to the vehicle body, so as to realize the mutual fixation of the first mounting plate 2 and the vehicle body, and the structure is simple and practical. Further, in the embodiment of the present application, the first mounting holes 201 are provided in two, and the two first mounting holes 201 are symmetrically distributed on the opposite sides of the ball socket 3. In this way, it is ensured that after the first mounting plate 2 and the vehicle body are fixed to each other, the left and right sides of the ball socket 3 are balanced in force, which is conducive to strengthening the installation firmness of the first mounting plate 2 and the vehicle body.
[0045] In addition, it should be noted that in the embodiments of the present application, Fig. 9 , the second mounting plate 5 is provided with at least two second mounting holes 501, and the second mounting holes 501 are used for the second fixing bolts (not shown in the drawings) to pass through; in this way, the second fixing bolts pass through the second mounting holes 501 and are fixedly connected to the back door, so as to realize the mutual fixation of the second mounting plate 5 and the back door, and the structure is simple and practical. Further, in the embodiment of the present application, there are two second mounting holes 501, and the two second mounting holes 501 are arranged in a linear array along the length direction of the second mounting plate 5. In this way, it is ensured that after the second mounting plate 5 and the back door are fixed to each other, when the back door and the vehicle body are opened or closed, the back door can smoothly drive the second mounting plate 5 to slide along the opening groove 302.
[0046] Further, in some embodiments of the present application, refer to the attached Figure 1 An adjustment gap 7 is provided between the inner side wall of the ball socket 3 and the outer surface of the ball head 6. With such a configuration, the relative position between the ball socket 3 and the ball head 6 can be finely adjusted by utilizing the adjustment gap 7, and the first mounting plate 2 and the second mounting plate 5 are further not affected by the installation flatness, and the deviation of the installation surface flatness is absorbed by the adjustment gap 7, thereby reducing the requirements for the accuracy of components.
[0047] On this basis, in some embodiments of the present application, refer to the attached Figure 5-8 And attached Fig.10 , the ball socket 3 is provided with a plurality of adjustment holes 303, the adjustment holes 303 are used to install the adjustment member 8, so as to limit the ball head member 6 located inside the ball socket 3 by using the adjustment member 8. With such a configuration, considering the existence of the adjustment gap 7, a certain spherical movement space of the ball head member 6 is provided inside the ball socket 3; during normal use of the automobile, the spherical movement space is not conducive to the connection firmness between the vehicle body and the back door. Therefore, after the first mounting plate 2 and the second mounting plate 5 are respectively installed with the vehicle body and the back door, the depth of the adjustment member 8 inserted into the adjustment hole 303 is used to reduce its spherical movement space, so that it can limit the ball head member 6 located inside the ball socket 3.
[0048] In addition, it should be noted that, in the embodiment of the present application, the ball socket 3 includes at least three adjustment holes 303, and the plane determined by the at least three adjustment holes 303 is defined as the adjustment hole 303 plane, and the ball center point of the ball socket 3 is located on the adjustment hole 303 plane. In this way, based on the principle that three points determine a plane, the adjustment holes 303 are set to at least three, and in the embodiment of the present application, the adjustment holes 303 are set to three. And the ball center point of the ball socket 3 is located on the plane of its adjustment hole 303, so that the three adjustment members 8 cooperate with each other to adjust the position of the ball head member 6, so that the ball center point of the ball head member 6 coincides with the ball center point of the ball socket 3, which is conducive to improving the smoothness of the spherical member relative to the ball socket 3 when it moves, and avoiding the rotation jam of the two due to the deviation of the ball center point.
[0049] It should be noted that in the embodiments of the present application, the specific forms of the adjustment hole 303 and the adjustment member 8 are not limited, and they can be configured according to actual conditions. For example, in some embodiments of the present application, the adjustment hole 303 is provided with a threaded structure, the adjustment member 8 includes a threaded portion, and the adjustment member 8 is threadedly matched with the adjustment hole 303; in this way, the connection between the adjustment member 8 and the adjustment hole 303 is achieved by threaded matching, and the structure is simple and practical. At the same time, by adjusting the adjustment member 8 to be screwed into the internal depth of the ball socket 3, and using the end of the adjustment member 8 to abut against the ball head member 6, it is conducive to achieving the operability of the ball center point of the ball head member 6 and the ball center point of the ball socket 3 to coincide with each other.
