the location shaft hole includes from first terminal surface along the round hole section 32 and the taper hole section 31 that the axial distributes in proper order, and taper hole section 31 and round hole section 32 all are used for locating with the cooperation of hinge frock.
Fig. 2 is a cross-sectional view taken along the direction B-B in fig. 1, and hatching is not added to clearly show the structure of the positioning shaft hole and the like. The leftmost end surface of the hinge shaft 30 in fig. 2 is the above-described first end surface.
The first hinge portion 10 is mainly used for connecting with a vehicle body, and the second hinge portion 20 is mainly used for connecting with a vehicle door. The operation principle and the connection mode of the first hinge portion 10 can refer to the operation and the assembly mode of the general car body hinges, and the operation principle and the connection mode of the second hinge portion 20 can refer to the operation and the assembly mode of the general car door hinges.
Wherein, the end of the hinge shaft 30 far away from the positioning shaft hole is provided with a pin cap 33, and a rivet pressing gasket 35 is arranged between the pin cap 33 and the second hinge part 20. The clinch spacer 35 prevents the second hinge portion 20 from being deformed by pressure during the clinching process.
Wherein, the middle part of the hinge shaft 30 is provided with a separating ring 34, the first hinge part 10 is positioned between the separating ring 34 and the positioning shaft hole, and the second hinge part 20 is positioned between the separating ring 34 and the pin cap 33.

In a simple aspect, the upper hinge and the lower hinge of the vehicle door can be accurately positioned due to the fact that the conical hole section 31 and the circular hole section 32 are respectively matched with the hinge tool, the stability after positioning is guaranteed, dislocation and other situations are not prone to occurring in the assembling process, the coaxiality of the upper hinge and the lower hinge after final assembling and forming is guaranteed to be good, and various using problems are avoided.
Specifically, referring to fig. 2, in the present embodiment, the conical hole section 31 is a conical hole, the circular hole section 32 is a circular hole, and the hole wall of the conical hole is connected with the hole wall of the circular hole. The gradual change of the hole pattern can better ensure the stability of matching with the hinge tool. It is understood that the taper hole section 31 may be designed as a circular hole, and the taper hole is designed in the present embodiment to fit the existing tooling, but this is not necessarily so. All the hole sections are designed into conical holes, and the hinge tool and the hinge shaft 30 cannot be out of fit as long as the effective positioning length is long.
In detail, the length of the taper hole section 31 in the present embodiment is 1 to 4mm, and preferably, the length is 2.3 mm. The length of the circular hole section 32 is 3-5 mm. The length of each hole section is only a reference, and the hinge shaft 30 with a proper hole section length can be selected according to the hinge tool condition of the assembly site.

The gradually changing outer diameter of the circular hole portion can facilitate guiding the first hinge portion 10 to be sleeved on the hinge shaft 30.
For example, taking the view of fig. 2 as an example, the first hinge portion 10 can be sleeved on the hinge shaft 30 from left to right, and since the outer diameter of the circular hole portion is gradually increased, the first hinge portion 10 can be guided and sleeved gradually, so as to improve the assembly efficiency and accuracy.
In the present embodiment, the conical hole section 31 and the circular hole section 32 are coaxially arranged, and the axis of the conical hole section 31 is collinear with the axis of the hinge shaft 30.
The axes of the taper hole section 31, the round hole section 32 and the hinge shaft 30 are designed in a collinear way, so that force can be applied on a straight line when a worker carries out clamping, the force application direction is also along the axis of the hinge shaft 30, dislocation is avoided, and good coaxiality of the upper hinge and the lower hinge of the vehicle door can be further ensured.
It can be understood that the present embodiment is mainly directed to a tool used in a conventional door hinge, and if the positioning structure of the tool itself is different for convenience of assembly, a door hinge rotating shaft structure in which the axis of the hinge shaft 30 is not collinear with the axes of the tapered hole section 31 and the circular hole section 32 may be considered. It should be noted that the axis of the hinge shaft 30 is not collinear with the axes of the conical hole section 31 and the circular hole section 32, but at least the axis of the hinge shaft 30 is required to be parallel to the axes of the conical hole section 31 and the circular hole section 32, and the direction of the applied force is also required to be parallel to the axis of the hinge shaft 30, so as to avoid the occurrence of misalignment as much as possible to ensure coaxiality.
For example, when the hinge shaft 30 of the upper hinge and the lower hinge of the vehicle door needs to maintain coaxiality when being positioned, but the appearance of the vehicle body is special, or the appearance of the vehicle door is special, so that the positioning structure of the conventional hinge tool is inconvenient to directly use, a tool which is not interfered by the appearance of the vehicle door or the vehicle body can be selected, and then a vehicle door hinge rotating shaft structure which is collinear with the axes of the taper hole section 31 and the circular hole section 32 and is not collinear with the axis of the hinge shaft 30 is correspondingly used.
In a word, as long as can ensure that the location structure of hinge frock plays the effect during the assembly for the upper and lower hinge of door keeps the axiality can.
The principle of the embodiment is as follows:
in prior art, the door generally relies on hinge structure to articulate with the automobile body, the upper and lower position of door all can set up corresponding hinge structure, but the axiality when guaranteeing the assembly is not easy, current hinge frock can be through fixing a position then the assembly on the pivot, but discovery in the practice, because on-line frock design defect and part self pressure rivet process problem, make even if also difficult location as the pivot of best locating position, thereby make the axiality of hinge about the door not ideal enough, lead to except general outward appearance problem, the door latch has still appeared, close difficult scheduling problem, greatly influence the use experience.
Research shows that the effective positioning length of the positioning part of the shaft pin of the existing hinge structure is insufficient, and the positioning part cannot be stably matched with a hinge tool.
Therefore, the door hinge pivot structure of this application has seted up the location shaft hole specially to designed into the structure that has taper hole section 31, round hole section 32, so can be compared with the hole of current axle, wholly increase the effective length in location, make hinge frock can with hinge pin 30 stable cooperation.
The location shaft hole passes through the machine tooling shaping, and its precision is high, has increased the effective length in location in addition, and the defect problem that solution technology and frock that can be fabulous brought guarantees that the axiality of hinge accords with the requirement about the door for door hinge pivot structure is more stable on the door.
For different tools, the profiles of the tapered hole section 31 and the circular hole section 32 can be further designed, for example, the circular hole is matched with the tapered hole in the embodiment, in other embodiments, the profiles can be changed into matched profiles to match the tools, and the length of the hole section can be selected according to actual requirements, so that the purpose of improving the positioning stability is finally achieved, and a plurality of corresponding problems caused by assembly are solved.
To sum up, the door hinge pivot structure of this application has the location shaft hole of taper hole section 31 and circle hole section 32 through designing hinge pin 30 for hinge pin 30 can have better cooperation with the hinge frock, makes the upper and lower hinge of door because the location is accurate and stable when the assembly, finally has good axiality, satisfies the assembly requirement, has overcome when the assembly a great deal of problems that the location is inaccurate or the unstability brings.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
