[0042] First embodiment

[0043] Figures 1 to 5 The first embodiment of the present application is shown. Figure 3 The vehicle door hinge structure provided in this embodiment includes: a vehicle body page 1, a tightening bolt 2, a hinge shaft 3, and vehicle door pages 4 and 5.

[0044] The difference from the prior art is that the door leaf is no longer a separate, integrally formed component, but contains a fixed part and an angle control part inside.

[0045] Wherein, the fixed part is fixedly connected with the hinge shaft. Once the door hinge structure is assembled, the fixed part is immovable and non-rotatable relative to the hinge shaft.

[0046] The angle control part is completely different. Even after the transfer is completed, the angle control part can still rotate relative to the hinge axis. Since the fixed part is stationary relative to the hinge axis, this rotation also occurs relative to the fixed part.

[0047] The reason for this rotation is that an annular outer tooth is arranged on the outer side of the angle control part. The annular outer tooth meshes with the annular inner tooth of the fixed part. Through the meshing between the two, the angle control part can rotate freely relative to the fixed part in the installation position.

[0048] In addition to the annular outer teeth, the angle control part is also equipped with a protrusion. It is called a protrusion because it protrudes outside the overall circumference of the angle control part. The function of setting the protrusion is to limit the position. Where the protrusion is set on the outer circumference determines the maximum opening of the door during use. Since the angle control part can rotate relative to the fixed part, the actual setting position of the protrusion can be adjusted, and therefore, the maximum opening of the door can also be adjusted. The specific adjustment method is to let the angle control part rotate clockwise or counterclockwise relative to the fixed part.

[0049] In this embodiment, the protrusion and the annular external teeth are formed on the same outer circle. In other words, the protrusion and the annular external teeth are arranged in the same plane. Figure 4 The angle control part is in the shape of a circular ring as a whole, and an annular outer tooth and a protrusion are arranged on the outer side of the circular ring. The only difference is that the annular outer tooth is on one side of the outer circle, and the protrusion is on the other side of the outer circle.

[0050] Since the protrusion and the annular outer teeth are located on the outer side of the same circumference, the annular outer teeth cannot cover the entire outer circumference. In this embodiment, the annular outer teeth occupy more than two-thirds of the entire outer circumference. At the other third position, a protrusion can be selected.

[0051] The annular outer teeth match the annular inner teeth of the fixed part. Figure 3 and Figure 4 In this embodiment, the annular inner teeth are arranged to protrude from the bottom surface of the fixed part.

[0052] Furthermore, since the annular outer teeth do not completely cover the circumference of the outer circle, in this embodiment, the annular inner teeth do not necessarily completely cover the circumference of the inner circle. Figures 1 to 5 As shown, in this embodiment, the inner circle may be an incomplete ring, and only a portion of the inner side of the ring is provided with annular inner teeth.

[0053] In addition, in this embodiment, the inner diameter of the annular inner teeth should be larger than the outer diameter of the annular outer teeth. The reason for this requirement is to ensure that the annular inner teeth and the annular outer teeth can rotate freely. Once the inner diameter of the annular inner teeth is smaller than the outer diameter of the annular outer teeth, the two cannot mesh.

[0054] In this embodiment, the protruding portion and the annular outer teeth are arranged on the same circumference, thereby achieving free rotation between the annular outer teeth and the annular inner teeth, thereby achieving free adjustment of the door opening.

[0055] Second embodiment

[0056] Figures 6 to 9The second embodiment of the present application is shown. The difference between this embodiment and the first embodiment is that the annular inner teeth of the fixed part are no longer arranged on the bottom surface of the door leaf, but are embedded in the bottom surface. At the same time, in the angle control part, the annular outer teeth and the protrusion are no longer arranged on the same circumference, but the annular outer teeth are arranged in two mutually parallel planes on the protrusion. In other words, the annular outer teeth and the protrusion are arranged on different circumferences.

[0057] Specifically, see Figures 6 to 9 On the circumference of the protrusion, a cylindrical body is protruding upward. The side of the protruding cylindrical body is provided with an annular outer tooth for realizing rotation.

[0058] In addition, this embodiment is different from the first embodiment of the utility model in that the outer circumference is fully covered with annular external teeth, and the inner circumference of the fixed part is also fully covered with annular internal teeth. This is completely different from the situation in the first embodiment where only part of the outer circumference is provided with annular external teeth and only part of the inner circumference is provided with annular internal teeth.

[0059] In order to realize the free rotation between the angle control part and the fixed part, the outer diameter of the outer peripheral surface should be slightly smaller than the inner diameter of the inner peripheral surface. Only in this way can the annular outer teeth mesh with the annular inner teeth.

[0060] The function of the protrusion is still to limit the position. That is, during the rotation of the door, the protrusion blocks the door, which can effectively limit the position of the maximum opening of the door. Moreover, by rotating the angle control part and the fixed part, the position of the protrusion can be effectively adjusted, thereby completing the adjustment of the door opening.

[0061] This embodiment realizes free rotation between the annular outer teeth and the annular inner teeth by arranging the protruding part on different circumferences, thereby realizing free adjustment of the door opening.

[0062] Third embodiment

[0063] Fig.10 and Fig.11 The third embodiment of the present application is shown. Fig.10 and Fig.11 The damping device includes an outer sleeve 61, a sliding block 62, a compression spring 63 and a wedge block 64. One end of the sliding block 62 is sleeved in the outer sleeve 61, and the compression spring 63 is arranged in the outer sleeve 61. The two ends of the compression spring 63 are respectively against the outer sleeve 61 and the sliding block 62. The wedge block 64 is axially connected to the other end of the sliding block 62 and is pressed against the toothed surface of the angle control part 4.

[0064] Initially, the wedge block 64 presses against the toothed surface of the angle control part 4, thereby jamming the angle control part 4. When in use, under the action of external force, the angle control part 4 is bendable to make the angle control part 4 rotate relative to the fixed part 5, the angle control part 4 drives the hinge shaft 3 to rotate, the hinge shaft 3 drives the gear of the angle control part 4 to rotate, the gear overcomes the resistance of the wedge block 64 and rotates. At this time, the gear squeezes the wedge block 64, thereby squeezing the sliding block 62, the sliding block 62 squeezes the compression spring 63, causing the compression spring 63 to deform, and when the external force is released, the compression spring 63 restores the deformation, driving the sliding block 62 to slide, the sliding block 62 drives the wedge block 64 to press against the toothed surface of the gear, thereby realizing damping of the rotation of the angle control part, making it less likely to cause misoperation in the adjustment operation of the opening.

[0065] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the system or device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description.
