[0002] At present, the sliding door assembly of the car uses a sliding door hinge to connect the door and the body.

Figure 1 As shown, a common sliding door hinge can be divided into a female hinge 1' and a male hinge 2', wherein the female hinge 1' is used for fixed connection with the vehicle door, and the male hinge 2' is used for sliding connection with the slide rail. The female hinge 1' and the male hinge 2' are fixed in relative position by at least two bolts 3', and the relative positions of the female hinge 1' and the male hinge 2' are adjusted and then the bolts 3' are tightened to achieve the adjustment of the sliding door hinge in the width direction of the vehicle body, thereby achieving the adjustment of the surface difference between the vehicle door and the vehicle body.
[0003] In the prior art, the method for adjusting the size of the sliding door hinge is to use a heavy object to hit the male hinge to achieve displacement of the male hinge relative to the female hinge, thereby achieving the purpose of adjusting the size of the sliding door hinge.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0038] In a first aspect, the present application provides a sliding door hinge structure, referring to the attached Figure 2-5 ,include:
[0039] A first hinge member 1 and a second hinge member 2;
[0040] A displacement component 3, the displacement component 3 is used to drive the first hinge member 1 to move relative to the second hinge member 2;
[0041] The fixing component 4 is used to fix the first hinge component 1 and the second hinge component 2 to each other.
[0042] The sliding door hinge structure provided in the embodiment of the present application directly installs a displacement assembly 3 on the sliding door hinge structure, and uses the displacement assembly 3 to drive the first hinge member 1 to displace relative to the second hinge member 2, thereby achieving the size adjustment of the sliding door hinge. After the size adjustment of the sliding door hinge is completed, the first hinge member 1 and the second hinge member 2 can be fixed to each other by the fixing assembly 4.
[0043] Since the size adjustment of the sliding door hinge is achieved by driving the displacement component 3, which is different from the prior art that uses heavy objects to manually knock to cause displacement, the displacement component 3 can accurately determine the displacement of the first hinge part 1 relative to the second hinge part 2, so as to effectively improve the accuracy of the sliding door hinge size adjustment.
[0044] Specifically, the first hinge component 1 is provided with a first through hole portion 101; the second hinge component 2 is provided with an axle pin hole 201, and the orthographic projection area of the axle pin hole 201 is located within the range of the orthographic projection area of the first through hole portion 101; the displacement assembly 3 includes a connected axle pin rod 301 and a rotating member 302, the rotation axis of the axle pin rod 301 and the central axis of the rotating member 302 are parallel to each other and the two are located on non-coaxial straight lines; the axle pin rod 301 is installed in the axle pin hole 201, the rotating member 302 is located on the inner side of the hole of the first through hole portion 101, and at least part of the outer side of the rotating member 302 abuts against the inner side wall of the first through hole portion 101; when the axle pin rod 301 rotates around the axle pin hole 201, the rotating member 302 performs eccentric rotation relative to the axle pin rod 301; at the same time, the rotating member 302 abuts against the inner side wall of the first through hole portion 101 to drive the first hinge component 1 to displace relative to the second hinge component 2. In this arrangement, since the rotation axis of the shaft pin 301 and the central axis of the rotating member 302 are parallel to each other and the two are located on non-colinear lines, that is, an eccentric design is adopted between the shaft pin 301 and the rotating member 302; when the shaft pin 301 rotates around the shaft pin hole 201, the rotating member 302 performs eccentric rotation relative to the shaft pin 301. At the same time, since the rotating member 302 is located inside the hole of the first through hole portion 101, and at least part of the outer side of the rotating member 302 abuts against the inner side wall of the first through hole portion 101, and since the shaft pin hole 201 is provided on the second hinge member 2 and the first through hole portion 101 is provided on the first hinge member 1; therefore, when the rotating member 302 performs eccentric movement, its outer side abuts against the inner side wall of the first through hole portion 101, so as to drive the first hinge member 1 to move relative to the second hinge member 2, thereby realizing the size adjustment of the sliding door hinge. The eccentric rotation angle of the rotating member 302 can be controlled manually, so the displacement component 3 can accurately determine the displacement of the first hinge member 1 relative to the second hinge member 2 .
[0045] It should be noted that, in the embodiment of the present application, the first hinge 1 is used for fixed connection with the vehicle body, and the second hinge 2 is used for sliding connection with the slide rail; or, the first hinge 1 is used for sliding connection with the slide rail, and the second hinge 2 is used for fixed connection with the vehicle body. With such arrangement, combined with the introduction of the background technology, when the first hinge 1 is used for fixed connection with the vehicle body, and the second hinge 2 is used for sliding connection with the slide rail, the first hinge 1 is a female hinge, and the second hinge 2 is a male hinge; when the first hinge 1 is used for sliding connection with the slide rail, and the second hinge 2 is used for fixed connection with the vehicle body, the first hinge 1 is a male hinge, and the second hinge 2 is a female hinge. It can be seen from this that the arrangement scheme of the first through hole portion 101 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.
[0046] In some embodiments of the present application, reference Figure 2The fixing assembly 4 includes a first fixing member 401 and a pressing plate member 402 connected to each other; the first hinge member 1 is provided with a second through hole portion 102 for the first fixing member 401 to pass through; the second hinge member 2 is provided with a second fixing member 202. When the first fixing member 401 passes through the second through hole portion 102 and is fixedly connected with the second fixing member 202, the pressing plate member 402 and the first hinge member 1 abut against each other, so that the first hinge member 1 is fixed between the pressing plate member 402 and the second hinge member 2. In this way, when the size of the sliding door hinge is adjusted, by passing the first fixing member 401 through the second through hole portion 102 located in the first hinge member 1 and being fixedly connected with the second fixing member 202 located in the second hinge member 2, the pressing plate member 402 and the first hinge member 1 abut against each other, so that the first hinge member 1 is pressed and fixed between the pressing plate member 402 and the second hinge member 2, thereby achieving mutual fixation of the first hinge member 1 and the second hinge member 2. The embodiment of the present application has a simple structure and strong practicality.
[0047] It should be noted that, in the embodiment of the present application, since the first hinge 1 will be displaced relative to the second hinge 2, in order to ensure that no matter how the relative position between the first hinge 1 and the second hinge 2 changes, the first fixing member 401 can pass through the second through hole portion 102 and be fixedly connected to the second fixing member 202; therefore, it is necessary to define the positional relationship between the second through hole portion 102 and the second fixing member 202. Specifically, the orthographic projection area of the second through hole portion 102 is larger than the orthographic projection area of the second fixing member 202, and the orthographic projection area of the second fixing member 202 is located within the range of the orthographic projection area of the second through hole portion 102. The part where the orthographic projection area of the second through hole portion 102 is larger than the orthographic projection area of the second fixing member 202 is used as the moving space for the displacement of the first hinge 1 relative to the second hinge 2; at the same time, the orthographic projection area of the second fixing member 202 is located within the range of the orthographic projection area of the second through hole portion 102, so as to ensure that the first fixing member 401 can always pass through the second through hole portion 102 and be fixedly connected to the second fixing member 202.
[0048] In addition, it should be noted that in the embodiments of the present application, the specific forms of the first fixing member 401 and the second fixing member 202 are not limited, and they can be configured according to actual conditions. For example, in some embodiments of the present application, the first fixing member 401 can be selected as a threaded rod; the second fixing member 202 can be selected as a threaded hole, and the threaded rod and the threaded hole are threadedly matched. In this way, the purpose of mutually fixing the first fixing member 401 and the second fixing member 202 is achieved by mutually threading the threaded rod and the threaded hole. The embodiments of the present application have a simple structure and strong practicality.
[0049] In some embodiments of the present application, reference Figure 2The rotating member 302 adopts a cylindrical structure, and the annular outer portion of the rotating member 302 of the cylindrical structure abuts against the inner wall of the first through hole portion 101. In this way, the rotating member 302 is set as a cylindrical structure, that is, the outer portion of the rotating member 302 is a smooth arc surface, so that when the outer portion of the rotating member 302 abuts against the inner wall of the first through hole portion 101, there is no obvious concave and convex position between the two, which is conducive to improving the smoothness of the rotating member 302 abutting against the inner wall of the first through hole portion 101 to drive the first hinge member 1 to move relative to the second hinge member 2.
[0050] Further, in some embodiments of the present application, referring to Figure 1 and Figure 2 , the first through hole portion 101 adopts a square hole structure, the width of the first through hole portion 101 of the square hole structure is equal to the cross-sectional diameter of the rotating member 302 of the cylindrical structure, and the length of the first through hole portion 101 of the square hole structure is greater than the cross-sectional diameter of the rotating member 302 of the cylindrical structure. In this arrangement, since the width of the first through hole portion 101 of the square hole structure is equal to the cross-sectional diameter of the rotating member 302 of the cylindrical structure, when the rotating member 302 undergoes eccentric rotation, at least part of its outer portion must abut against the inner side wall of the first through hole portion 101, thereby effectively driving the first hinge member 1 to move relative to the second hinge member 2. At the same time, the length of the first through hole portion 101 of the square hole structure is greater than the cross-sectional diameter of the rotating member 302 of the cylindrical structure, so that the first through hole portion 101 leaves a movable space for the rotating member 302 to undergo eccentric rotation.
[0051] Specifically, refer to Figure 3-5 ,definition Figure 3 When the rotating member 302 rotates counterclockwise, the reference Figure 4 Since the outer side of the rotating member 302 abuts against the inner side wall of the first through hole 101, the rotating member 302 abuts against the inner side wall of the first through hole 101 to drive the first hinge member 1 to move to the right relative to the second hinge member 2. At this time, the overall lateral length of the sliding door hinge increases; when the rotating member 302 rotates clockwise, Figure 5 Since the outer side of the rotating member 302 abuts against the inner side wall of the first through hole portion 101, the rotating member 302 abuts against the inner side wall of the first through hole portion 101 to drive the first hinge member 1 to move to the left relative to the second hinge member 2. At this time, the overall lateral length of the sliding door hinge is shortened. It can be seen that the size adjustment of the sliding door hinge can be achieved through the above technical solution.
[0052] In some embodiments of the present application, the first hinge component 1 is provided with a marking line 103, and the second hinge component 2 is provided with a scale line 203; when the first hinge component 1 is displaced relative to the second hinge component 2, the marking line 103 is displaced accordingly on the scale line 203. In this way, by observing the position of the marking line 103 on the scale line 203, the displacement of the first hinge component 1 relative to the second hinge component 2 can be confirmed, which helps to further improve the accuracy of the sliding door hinge size adjustment.
[0053] In some embodiments of the present application, at least part of the rotating member 302 protrudes from the first through hole portion 101; the part of the rotating member 302 protruding from the first through hole portion 101 is defined as a hand-held portion 3021, and the hand-held portion 3021 is used for an operator to hold the rotating member 302 to rotate around the shaft pin 301. In this way, the operator holds the part of the rotating member 302 protruding from the first through hole portion 101 to perform an eccentric rotation movement on the rotating member 302 around the shaft pin 301, thereby driving the first hinge member 1 to move relative to the second hinge member 2. The embodiment of the present application has a simple structure and strong practicality.
[0054] Alternatively, a socket portion 3022 is provided on a side of the rotating member 302 away from the shaft pin 301, and the socket portion 3022 is used for inserting the rotating rod, so that the rotating rod is rotated to drive the rotating member 302 to rotate around the shaft pin 301. This arrangement is similar to the mechanism of a key rotating to open a door. The operator inserts the rotating rod into the socket portion 3022, and rotates the rotating rod to drive the rotating member 302 to perform an eccentric rotational movement around the shaft pin 301, thereby driving the first hinge member 1 to move relative to the second hinge member 2. The embodiment of the present application has a simple structure and strong practicality.
[0055] It can be understood that the above two embodiments are both about how to effectively drive the rotating member 302 to rotate around the axis pin 301. Those skilled in the art may choose one of the above two embodiments or adopt them simultaneously, and the present application does not impose any specific restrictions thereon.
