Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to a lightweight hinge structure. Background Art
[0002] Hinge is one of the commonly used auto parts, which is often used to connect the door and the body, so that the door can rotate around the body in a fixed track to realize the door opening and closing. Traditional door hinges use a single long rivet pin as the rotation connection point between the door and the body. The long rivet pin is under great pressure and there are certain risks. In addition, the hinge is made of metal material and has a heavy structure, which makes the overall weight relatively large. Utility Model Content
[0003] The utility model aims to provide a lightweight hinge structure, which has the advantages of stable structure and light weight.
[0004] The technical solution of the utility model is as follows:
[0005] The hinge structure of claim 1, wherein the upper edges of the upper and lower edges of the vertical plates on the left and right sides of the hinge are aligned with each other, and the hinge has two projections on the top and bottom of the upper edges of the vertical plates. The projections are symmetrical with respect to each other, and the shape of the top of the mounting plate matches that of the circular groove. The top of the mounting plate is placed in the circular groove. The circular groove and the top of the mounting plate are provided with insertion holes at the center of the circle. Short rivet pins are installed in the overlapping insertion holes. The circular groove and the top of the mounting plate rotate with each other around the short rivet pin. The short rivet pins on the left and right sides are located on the same straight line. The short rivet pin, the circular groove and the top of the mounting plate at the same location coincide with the central axis. The front and rear ends of the circular arc outer edge of the top of the mounting plate are provided with projections that cannot be rotated into the circular groove. When the door connected to the door connecting plate is turned to a closed state or a maximum open state, the projection abuts against the two ends of the opening outer edge of the circular groove.
[0006] Preferably, extension plates are provided at both ends of the outer edge of the opening of the circular groove, and when the vehicle door is turned to a closed state or a maximum open state, the extension plates can abut against the protrusions on the top of the mounting plate.
[0007] Preferably, a square notch is provided in the middle of the transverse plate of the vehicle body connecting plate.
[0008] Preferably, the vehicle body connecting plate and the door connecting plate are made of aluminum alloy.
[0009] The utility model has the following beneficial technical effects:
[0010] 1. The rotational connection between the door connecting plate and the body connecting plate is achieved by inserting short rivet pins into overlapping sockets and limiting the top of the mounting plate to rotate in a circular groove. Compared with the general door hinge structure, the pressure borne by the short rivet pins here is shared, which improves the structural stability. Protrusions are set at both ends of the outer edge of the top of the mounting plate. Since the protrusions cannot be rotated into the circular groove, the rotation angle of the door connecting plate connected to the mounting plate and the door connected to the door connecting plate is limited within a reasonable range.
[0011] 2. The material of the circular groove part on the body connecting plate is removed, and the commonly used long rivet pin is replaced with two short rivet pins with a smaller total weight, thereby reducing the total weight of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the figure: 1-body connecting plate, 2-door connecting plate, 3-circular groove, 4-mounting plate, 5-hole, 6-short rivet pin, 7-protrusion, 8-extension plate, 9-square notch. DETAILED DESCRIPTION
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] Example:
[0019] like Figures 1 to 3As shown, the present embodiment provides a lightweight hinge structure, including a body connecting plate 1 and a door connecting plate 2, the body connecting plate 1 is U-shaped, and the inner sides of the upper ends of the vertical plates on the left and right sides of the body connecting plate 1 are respectively provided with circular grooves 3 corresponding to each other, and the door connecting plate 2 is provided with a left-right symmetrical mounting plate 4, the shape of the top end of the mounting plate 4 matches the shape of the circular groove 3, the top end of the mounting plate 4 is placed in the circular groove 3, the circular groove 3 and the top end of the mounting plate 4 are provided with a plug hole 5 at the center of the circle, and the overlapping plug holes 5 are loaded with short rivet pins 6, the circular groove 3 and the top end of the mounting plate 4 rotate with each other around the short rivet pin 6, the short rivet pins 6 on the left and right sides are located on the same straight line, the short rivet pin 6, the circular groove 3 and the top end of the mounting plate 4 coincide with the central axis, and the arc outer edge of the top end of the mounting plate 4 is provided with protrusions 7 that cannot be rotated into the circular groove 3 at the first and last ends. When the door connected to the door connecting plate 2 is turned to a closed state or a maximum open state, the protrusion 7 abuts against the two ends of the opening outer edge of the circular groove 3.
[0020] The rotational connection between the door connecting plate 2 and the body connecting plate 1 is achieved by inserting the short rivet pin 6 into the overlapping jack 5 and limiting the top of the mounting plate 4 to rotate in the circular groove 3. Compared with the general door hinge structure, the pressure borne by the short rivet pin 6 here is shared, which improves the structural stability. Protrusions 7 are respectively set at both ends of the outer edge of the top of the mounting plate 4. Since the protrusions 7 cannot be rotated into the circular groove 3, the rotation angle of the door connecting plate 2 connected to the mounting plate 4 and the door connected to the door connecting plate 2 is limited within a reasonable range. The material of the circular groove 3 is removed from the body connecting plate 1, and the commonly used long rivet pin is replaced with two short rivet pins 6 with a smaller sum of weights, thereby reducing the total weight of the entire structure.
[0021] Furthermore, extension plates 8 are provided at both ends of the opening outer edge of the circular groove 3. When the door is turned to a closed state or a maximum open state, the extension plates 8 can abut against the protrusion 7 on the top of the mounting plate 4. The extension plates 8 help to prevent the protrusion 7 from turning into the circular groove 3, thereby improving the blocking effect.
[0022] Furthermore, a square notch 9 is provided in the middle of the transverse plate of the vehicle body connecting plate 1. The square notch 9 reduces the material on the vehicle body connecting plate 1 and reduces the overall mass.
[0023] Furthermore, the vehicle body connecting plate 1 and the vehicle door connecting plate 2 are made of aluminum alloy. By selecting aluminum alloy with lower density, the overall weight is reduced.
[0024] The working principle and use process of this utility model:
[0025] When the car door is closed, the protrusion 7 at one end of the outer edge of the top of the mounting plate 4 abuts against the open end of the circular groove 3 and the extended plate 8 connected thereto. When the user opens the car door, the car door drives the connected door connecting plate 2 to rotate around the axis where the two short rivet pins 6 are located. When the car door is turned to the maximum open state, the protrusion 7 at the other end of the outer edge of the top of the mounting plate 4 abuts against the other end of the opening of the circular groove 3 and the extended plate 8 connected thereto.
[0026] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
