Referring to fig. 1 to 7, the present invention provides an automobile door hinge, including: door leaf 1, body leaf 2 and pivot 3.
Specifically, the door leaf 1 includes a first pivot portion 11, a first mounting portion 12, and a first connecting arm 13. The first connecting arm 13 is connected to the side of the first pivot portion 11 and the first mounting portion 12.
The first pivot joint is cylindrical or prismatic. The first pivot portion 11 has a first eccentric shaft hole 110. The first eccentric shaft hole is arranged along the axial direction of the first pivoting part. A stopping convex edge 111 is formed on one side of the first pivot part 11 far away from the first mounting part 12. The stopping convex edge is formed on the circumferential side surface of the first pivoting part. The stopping convex edge is arranged along the axial direction of the first pivoting part.
The body panel 2 includes a second pivot portion 21, a second mounting portion 22, and a second connecting arm 23. The second connecting arm 23 is connected to the side surface of the second pivot portion 21 and the second mounting portion 22. The second pivot portion 21 has a second eccentric shaft hole 210. The second eccentric shaft hole and the first eccentric shaft hole are coaxially arranged, and the inner diameter sizes of the second eccentric shaft hole and the first eccentric shaft hole are matched. The end surface of the second pivot portion 21 is opposite to the end surface of the first pivot portion 11. The second connecting arm 23 is extended to form a limit protrusion 221 for limiting the stop protrusion 111. The limiting convex edge is arranged along the axial direction of the second pivoting part.
The pivot shaft 3 is rotatably inserted into the first eccentric shaft hole 110 and the second eccentric shaft hole 210.
After the first pivoting part and the second pivoting part rotate relatively, the stop convex edge is supported on the limit convex edge to stop the rotation of the first pivoting part.
According to the automobile door hinge, the axis of the pivot, the first pivoting part and the second pivoting part are designed to be eccentric, so that the defects that different section steel or forging blanks are required to be adopted for processing at different axis positions and opening angles due to the fact that the axis of the hinge shaft of the hinge in the prior art is coaxial with the hinge end of the automobile body leaf and the hinge end of the door leaf, and different section steel or forging dies are required to manufacture a plurality of blanks with similar appearances are overcome, the production cost is greatly increased, and extra quality cost is caused due to the fact that materials are easy to mix.
The first eccentric shaft hole and the first pivot part, and the second eccentric shaft hole and the second pivot part of the automobile door hinge are respectively eccentrically arranged, so that products with different hinge axis positions can be processed by using the same blank in a certain range, and the requirements of automobile door hinges with different opening angles can be met. The invention can effectively utilize the section steel or the forging blank, improves the scale benefit, and reduces the types of the die and the blank, thereby reducing the cost and the quality risk.
In a preferred embodiment, an end of the stopping protrusion 111 away from the first pivot portion 11 is circular arc-shaped. The stop surface of the existing automobile door hinge product is generally planar or linear, and due to the machining tolerance, the actual contact position of the stop surface is uncertain, so that the error of the opening angle of the hinge is large. The stop convex edge 111 of the automobile door hinge has a circular arc-shaped end surface, so that the contact position of the stop surface is stabilized, and the precision of the opening angle is improved.
In the present embodiment, the first mounting portion 12 has a plate shape, and the first mounting portion 12 is disposed at an angle to the first connecting arm 13.
The second mounting portion 22 is plate-shaped, and the second mounting portion 22 is disposed at an angle to the second connecting arm 23.
The first mounting portion 12 is arranged perpendicular to the first connecting arm 13; the second mounting portion 22 is disposed perpendicular to the second connecting arm 23.
The eccentric direction of the first eccentric shaft hole 110 and the eccentric direction of the second eccentric shaft hole 210, and the eccentric distance of the first eccentric shaft hole and the eccentric distance of the second eccentric shaft hole 210 of the automobile door hinge of the present invention are set according to the installation position of the pivot shaft of the automobile door hinge on the automobile body and the opening angle of the automobile door.
In a preferred embodiment, the eccentric direction of the first eccentric shaft hole 110 and the eccentric direction and the eccentric distance of the second eccentric shaft hole 210 are set according to the position of the pivot of the door hinge on the vehicle body and the opening angle of the door, with the first mounting portion 12 and the second mounting portion 22 as reference surfaces.
Specifically, referring to fig. 3, the plate surface direction of the first mounting portion is taken as a first horizontal direction (X axis), and the axial direction of the first link arm is taken as a second horizontal direction (Y axis). When a rectangular coordinate system (XOY) is established with the positive axis of the first mounting portion as the origin O, the axis of the first eccentric shaft hole is offset in the second horizontal direction, and the axis of the first eccentric shaft hole is offset in the negative direction of the second horizontal direction (the negative direction of the Y axis). The plate surface direction of the second mounting portion is taken as a first horizontal direction (X axis), and the axial direction of the second connecting arm is taken as a second horizontal direction (Y axis). A rectangular coordinate system (XOY) is established with the positive axis of the second mounting portion as an origin O, the axis of the second eccentric shaft hole is disposed to be deviated in the second horizontal direction, and the axis of the second eccentric shaft hole is disposed to be deviated in the negative direction of the second horizontal direction (the negative direction of the Y axis).
Continuing to refer to fig. 4 and 5, fig. 4 shows the axis of the first eccentric shaft hole being offset to the negative direction of the first horizontal direction (the negative direction of the X axis); in FIG. 5, the axis of the first eccentric shaft hole is arranged in a positive direction (positive direction of X axis) deviated from the first horizontal direction. When the first eccentric shaft hole and the second eccentric shaft hole are respectively arranged along the first horizontal direction (X-axis direction) in an eccentric way and are arranged at different eccentric distances, the first eccentric shaft hole and the second eccentric shaft hole can be used for adjusting the opening angle of the automobile door hinge.
Continuing to refer to fig. 6 and 7, fig. 6 shows the axis of the first eccentric shaft hole being offset to the negative direction of the second horizontal direction (the negative direction of the Y axis); in FIG. 7, the axis of the first eccentric shaft hole is arranged in a direction (positive direction of Y axis) deviated from the positive direction of the second horizontal direction. When the first eccentric shaft hole and the second eccentric shaft hole are eccentrically arranged along the second horizontal direction (Y-axis direction) and are arranged at different eccentric distances, respectively, the distance between the axis of the pivot of the automobile door hinge of the present invention and the mounting surface (second mounting portion) can be adjusted.
The foregoing description is only exemplary of the preferred embodiments of the invention and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention herein disclosed is not limited to the particular combination of features described above, but also encompasses other arrangements formed by any combination of the above features or their equivalents without departing from the spirit of the invention. For example, the above features and (but not limited to) features having similar functions disclosed in the present invention are mutually replaced to form the technical solution.
