[0002] With the change of market demand and the development of technology, the novel structure of vehicles researched and produced by vehicle enterprises can obtain good response in the market, for example: the application of scissors door structure on the car, wherein the existing scissors door structure mainly includes a hinge, an extension link and a spring push rod, the hinge plays a crucial role in the opening height, opening degree and stability of the door, and the quality of the hinge directly determines the opening / closing action of the door.

[0003] For the scissors door hinge car, the cost and pricing are higher than that of the car with the flat door structure, the main reason is that when the scissors door hinge is just opened or about to be closed, the vertical displacement of the door in the height direction is large, which is different from the traditional flat door method, resulting in that the matching structure between the door and the vehicle body needs to be specially designed and cannot be universally replaced. Due to the small demand for cars with scissors door hinges, the production and inventory burden of manufacturers is increased.

[0004] Secondly, due to the large weight of the door, the traditional scissors door hinge is insufficient in rigidity or poor in stability, which leads to abnormal problems such as shaking and shaking during opening and closing of the door, and too large opening angle. SUMMARY

[0005] The purpose of the present application is to overcome the shortcomings of the prior art and provide a general, reliable and stable double-intersection scissors door hinge.

[0006] In order to achieve the above purpose, the double-intersection scissors door hinge provided by the present application comprises a mounting base and a hinge arm, the hinge arm is integrally extended and formed with a connecting part, further comprising a swing arm and a connecting arm, one end of the swing arm is hingedly connected with the mounting base to form a first axis; the other end of the swing arm is hingedly connected with the connecting part to form a second axis; the first axis and the second axis are not parallel and intersect to form an included angle, the size of the included angle is directly proportional to the maximum opening degree of the hinge arm in the height direction; the two ends of the connecting arm are respectively hingedly connected with a first rotating block and a second rotating block, wherein the first rotating block is hingedly connected to the mounting base; the second rotating block is hingedly connected with the connecting part.

[0007] Furthermore, the first rotating block is hinged to the mounting base to form a third axis; the first rotating block is hinged to the connecting arm to form a fourth axis; wherein the first axis, the third axis, and the fourth axis intersect at a first intersection point; the second rotating block is hinged to the connecting arm to form a fifth axis, and the second rotating block is hinged to the connecting part to form a sixth axis; wherein the second axis, the fifth axis, and the sixth axis intersect at a second intersection point.

[0008] Furthermore, the first intersection point and the second intersection point do not coincide.

[0009] Furthermore, the third axis is arranged perpendicular to the fourth axis.

[0010] Furthermore, the intersection point is located on the first rotating block.

[0011] Furthermore, the fifth axis is arranged perpendicular to the sixth axis.

[0012] Furthermore, the intersection point is located on the second rotating block.

[0013] Furthermore, the swing arm is formed with a limiting part that abuts and limits the connection part, wherein when the hinge arm is flipped up and opened to a predetermined opening degree, the limiting part abuts and limits the connection part.

[0014] Furthermore, the connecting part is integrally formed with a first branch and a second branch for connecting with the hinge arm, and the first branch, the second branch and the hinge arm are arranged in a triangular shape.

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the present application, the present application is described more fully below with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0026] Referring to the accompanying Figures 1-8 As shown in the figure, in the present embodiment, a double intersection scissors door hinge, comprising a mounting base 1, an arm 2, a swing arm 3 and a connecting arm 4, wherein the mounting base 1 is used for fixedly mounting to the vehicle body (not shown in the figure), and the arm 2 is used for fixedly mounting to the vehicle door (not shown in the figure). The arm 2 is integrally extended to form a connecting part 21; the connecting part 21 here can be adaptively designed according to the actual product requirements relative to the extension direction of the arm 2, which is not specifically limited here.

[0027] For ease of explanation, the accompanying Figure 8 For reference, the arm is defined as Y axis direction in horizontal transverse direction, and Z axis direction in height vertical direction.

[0028] Referring to the accompanying Figures 1-3As shown, in the present embodiment, one end of the swing arm 3 is hingedly connected with the first fixed part preformed on the mounting base 1, and the hingedly connected part forms a first axis a. The other end of the swing arm 3 is hingedly connected with the connecting part 21 of the hinge arm 2, and the hingedly connected part forms a second axis b. The first axis a and the second axis b are not parallel and intersect to form an included angle K, and the size of the included angle K is directly proportional to the maximum opening of the hinge arm 2 in the height direction. Specifically, the larger the included angle K, the larger the maximum opening of the hinge arm 2 in the height direction (Z-axis direction); on the contrary, the smaller the included angle K, the smaller the maximum opening of the hinge arm 2 in the height direction. Therefore, those skilled in the art can set the size of the included angle K according to the opening requirement of the vehicle door, which is not specifically limited here.

[0029] In the present embodiment, the two ends of the connecting arm 4 are respectively hingedly connected with a first rotating block 5 and a second rotating block 6. The first rotating block 5 is hingedly connected to the second fixed part preformed on the mounting base 1, and the second rotating block 6 is hingedly connected to the connecting part 21.

[0030] Specifically, referring to the accompanying drawings, Figure 4 As shown, the first rotating block 5 is hingedly connected with the mounting base 1 to form a third axis e, and the first rotating block 5 is hingedly connected with the connecting arm 4 to form a fourth axis f. The first axis a, the third axis e, and the fourth axis f intersect at a first intersection point A.

[0031] Specifically, referring to the accompanying drawings, Figure 5 and 6 As shown, the second rotating block 6 is hingedly connected with the connecting arm 4 to form a fifth axis d, and the second rotating block 6 is hingedly connected with the connecting part 21 to form a sixth axis c. The second axis b, the fifth axis d, and the sixth axis c intersect at a second intersection point B.

[0032] Further, the first intersection point A and the second intersection point B do not coincide, wherein the intersection point A is located on the first rotating block 5, and the intersection point B is located on the second rotating block 6.

[0033] Therefore, by dividing the first axis a, the third axis e, the fourth axis f, the second axis b, the fifth axis d, and the sixth axis c into two groups, and respectively intersecting at the first intersection point A and the second intersection point B, the opening and closing actions of the hinge arm 2 are more stable and reliable, effectively solving the problem of easy shaking during opening and closing of the vehicle door.

[0034] In the present embodiment, the third axis e and the fourth axis f are arranged perpendicularly, and the fifth axis d and the sixth axis c are arranged perpendicularly, further improving the stability of the opening and closing of the vehicle door.

[0035] In the present embodiment, referring to the accompanying drawings, Figure 5 and 6As shown, the swing arm 3 is formed with a limiting portion 31 which is in abutting limiting cooperation with the connecting portion 21, wherein when the hinged arm 2 is opened upward to a predetermined opening degree, the limiting portion 31 is in abutting cooperation with the connecting portion 21, thereby limiting the maximum opening degree of the hinged arm 2 by the abutting action of the limiting portion 31, and achieving the function of limiting protection, avoiding the situation of over opening of the door.

[0036] In the present embodiment, as shown in the schematic view of the hinged arm 2 in the closed state and the schematic view of the hinged arm 2 in the opened state in the attached drawings, in the process of upward or downward turning of the hinged arm 2, the connecting portion 21 rotates relative to the swing arm 3 around the second axis b and relative to the second rotating block 6 around the sixth axis c, at the same time, the swing arm 3 rotates relative to the mounting base 1 around the first axis a, the second rotating block 6 rotates relative to the connecting arm 4 around the fifth axis d, the connecting arm 4 rotates relative to the first rotating block 5 around the fourth axis f, and the first rotating block 5 rotates relative to the mounting base 1 around the third axis e, thereby the hinged arm rotates around the third axis e and the first axis a respectively, and the action of opening upward or closing downward is achieved. Figure 1 Figure 3 As shown in the schematic view of the hinged arm 2 in the closed state and the schematic view of the hinged arm 2 in the opened state in the attached drawings, in the process of upward or downward turning of the hinged arm 2, the connecting portion 21 rotates relative to the swing arm 3 around the second axis b and relative to the second rotating block 6 around the sixth axis c, at the same time, the swing arm 3 rotates relative to the mounting base 1 around the first axis a, the second rotating block 6 rotates relative to the connecting arm 4 around the fifth axis d, the connecting arm 4 rotates relative to the first rotating block 5 around the fourth axis f, and the first rotating block 5 rotates relative to the mounting base 1 around the third axis e, thereby the hinged arm rotates around the third axis e and the first axis a respectively, and the action of opening upward or closing downward is achieved.

[0037] Specifically, as shown in the attached drawings, when the hinged arm is opened upward, in the initial stage, the displacement of the hinged arm along the Z axis direction is small, and the displacement along the Y axis direction is large, so that the door can be smoothly moved out of the vehicle body; then, the hinged arm continues to turn along the predetermined parabolic trajectory, so that the displacement along the Z axis direction gradually increases, and the displacement along the Y axis direction gradually decreases, and finally the opening action of the hinged arm is achieved; on the contrary, when the hinged arm is closed downward, in the initial stage, the displacement of the hinged arm along the Z axis direction is large, and the displacement along the Y axis direction is small, then the hinged arm continues to turn along the predetermined parabolic trajectory, and when closing, the displacement along the Z axis direction gradually decreases, and the displacement along the Y axis direction gradually increases, so that the door can be smoothly moved into the vehicle body, and finally the opening action of the hinged arm is achieved. Based on this, when the door is initially opened or about to be closed, the hinged arm 2 at this time is mainly outwardly opened or inwardly closed horizontally along the Y axis direction, and the vertical displacement along the Z axis direction is negligible, and the opening and closing action at this time is similar to the opening and closing action of the conventional swing door, so that the door can be smoothly separated from or closed to the vehicle body. The scissor door hinge of the present embodiment can be directly applied to the conventional door without modification of the door and the vehicle body door lock, and has universality and replaceability, realizes platform production, and reduces the burden of spare parts cost of the vehicle enterprise.
