AI Technical Summary
In existing automotive scissor door hinges, the fixed design of the rear pin shaft relative to the vehicle body results in an increased gap between the outer wall of the door and the outer surface of the vehicle body, causing the door to not close tightly and making it difficult to adjust.
The reinforcing plate and rotating seat adopt a split structure. By rotating the rotating seat and the support arm, the door leaf is driven to rotate synchronously, changing the relative position between the door leaf and the body fender, adjusting the gap and improving flexibility.
This allows for adjustment of the relative position between the door panel and the body fender after parts production and installation, reducing gaps, improving the flexibility of the device, and enhancing the aesthetics of the vehicle surface.

[0001] This disclosure pertains to the field of automobile manufacturing, specifically relating to an adjustable single-axis hinge for automobile scissor doors. Background Technology
[0002] The hinge of a car scissor door is a key component for opening scissor doors. It adopts a unique structural design and is usually made of high-strength metal materials. It allows the door to open upwards at a near-vertical angle, which not only adds a futuristic and technological visual effect to the vehicle, but also makes it easier for passengers to enter and exit the vehicle, especially in narrow spaces.
[0003] However, in a detachable car door hinge as disclosed in CN208184483U, the movable door hinge and the fixed body hinge are connected by a pin. The movable door hinge and the fixed body hinge are fixedly connected to the door and the body respectively, so that the relative position of the pin and the body is fixed after fixing. However, when the gap between the outer wall of the door and the outer surface of the body increases, the door cannot be closed tightly, which makes it inconvenient to adjust. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this disclosure is to provide an adjustable single-axis hinge for automotive scissor doors, which solves the problem in existing technologies where the relative position of the fixed rear pin shaft and the vehicle body is fixed, but when the gap between the outer wall of the door and the outer surface of the vehicle body increases, causing the door to not close tightly, making adjustment inconvenient.
[0005] The objective of this disclosure can be achieved through the following technical solutions:
[0006] An adjustable single-axis hinge for an automotive scissor door includes: a body fender, a rotating base, and a reinforcing plate;
[0007] A reinforcing plate is bolted to the side of the vehicle fender, and a rotating seat is rotatably connected to the side wall of the reinforcing plate and the side wall of the vehicle fender. A support arm is rotatably connected to the side of the rotating seat near the reinforcing plate. A rotating hole is provided at the upper end of the rotating seat, and a first bolt adapted to the rotating hole is provided inside the rotating hole. A fixing hole adapted to the rotating hole is provided on the side of the reinforcing plate near the rotating seat.
[0008] The end of the support arm away from the vehicle fender is fixed with a door leaf.
[0009] In some disclosures, the rotating seat has at least one adjustment hole on the side near the reinforcing plate, and the reinforcing plate has a limiting hole adapted to the adjustment hole on the side near the rotating seat.
[0010] In some disclosures, a second bolt is provided inside the limiting hole, penetrating the rotating seat and the reinforcing plate, and the diameter of the second bolt is smaller than the diameter of the limiting hole.
[0011] In some disclosures, the reinforcing plate has multiple connection holes on the side near the vehicle fender.
[0012] In some disclosures, the inner side of the reinforcing plate is fixed with a reinforcing rib, and the reinforcing rib is located between the side wall of the vehicle body fender and the rotating seat.
[0013] In some disclosures, the rotating seat has a fixed shaft hole on the side near the support arm, and the support arm has a through hole corresponding to the shaft hole near the rotating seat, and a single rotating shaft is provided through the inner side of the through hole.
[0014] In some disclosures, the rotating seat has an arc-shaped groove on the side near the reinforcing plate, and the center of the arc-shaped groove coincides with the central axis of the rotating hole.
[0015] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0016] A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them;
[0017] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.
[0018] Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields.

[0030] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0031] Based on the concept of this application, combined with Figures 1 to 5 This document describes an embodiment of an adjustable single-axis hinge for automotive scissor doors. Specifically, this adjustable single-axis hinge for automotive scissor doors is constructed as a split structure, comprising three components: a body fender 1, a rotating base 4, and a reinforcing plate 5. When the gap between the outer wall of the door leaf 2 and the outer wall of the body fender 1 is too large, rotating the rotating base 4, which in turn drives the rotating base 4, support arm 3, and door leaf 2 to rotate synchronously, allows the relative position between the door leaf 2 and the body fender 1 to be changed after the parts are manufactured and installed. This reduces the gap between the door and the body, thereby improving the flexibility of the device and enhancing the aesthetics of the vehicle's surface.
[0032] Please refer to Figures 1 to 6An adjustable single-axis hinge for a car scissor door includes: a body fender 1, a rotating seat 4, and a reinforcing plate 5;
[0033] A reinforcing plate 5 is bolted to the side of the fender 1 of the vehicle body, and a rotating seat 4 is rotatably connected to the side wall of the fender 1 of the reinforcing plate 5. A support arm 3 is rotatably connected to the side of the rotating seat 4 near the reinforcing plate 5. A rotating hole 41 is provided at the upper end of the rotating seat 4, and a first bolt 6 that matches the rotating hole 41 is provided inside the rotating hole 41. A fixing hole 51 that matches the rotating hole 41 is provided on the side of the reinforcing plate 5 near the rotating seat 4.
[0034] The end of the support arm 3 away from the fender 1 is fixed with the door panel 2.
[0035] In use, the reinforcing plate 5, body fender 1, rotating seat 4, and door leaf 2 are separate structures. Before installing the door leaf 2 onto the body fender 1, one side of the reinforcing plate 5 is fitted against the side wall of the body fender 1 and fixed to the side wall of the body fender 1. Then, one side of the rotating seat 4 is fitted against the other side of the reinforcing plate 5, and the rotating hole 41 on the rotating seat 4 is coaxially aligned with the fixing hole 51 on the reinforcing plate 5. The first bolt 6 is then passed through the rotating hole 41 and the fixing hole 51 from one side of the rotating seat 4 until the end of the first bolt 6 penetrates the reinforcing plate 5. At this point, the nut 61 that matches the first bolt 6 is tightened to the end of the first bolt 6. Then, the support arm 3 is rotatably connected to the rotating seat 4 near the side wall of the body fender 1. One side of the reinforcing plate 5 is then fixed, and the door leaf 2 is fixed to the end of the support arm 3 away from the rotating seat 4. At this time, the door leaf 2 can be opened and closed, thereby driving the door leaf 2 to rotate along the hinge point between the support arm 3 and the rotating seat 4, so that the door leaf 2 and the support arm 3 move from the open position of the scissor door to the closed position along the hinge point of the support arm 3. In order to improve the stability of the rotation of the door leaf 2 and the support arm 3, in one case, the rotating seat 4 is fixedly connected to the reinforcing plate 5. If the positioning reference of the rotating seat 4 and the reinforcing plate 5 deviates from the design reference during the processing, the door leaf 2 cannot rotate to the appropriate position when the car door is closed, which increases the gap between the outer wall of the door leaf 2 and the outer wall of the body fender 1, thus affecting the overall aesthetics of the car. If the gap between the outer wall of the door panel 2 and the outer wall of the fender 1 is too large, even affecting the safety of the vehicle, the reinforcing plate 5 and the rotating seat 4 need to be remanufactured. Instead, the reinforcing plate 5 and the rotating seat 4 can be designed as separate structures. When the gap between the outer wall of the door panel 2 and the outer wall of the fender 1 is too large, the nut 61 and the first bolt 6 can be loosened, and the rotating seat 4 can be rotated along the central axis of the first bolt 6. This will cause the rotating seat 4, the support arm 3, and the door panel 2 to rotate synchronously. Since the central axis of the first bolt 6 does not coincide with the central axis of the hinge point of the support arm 3 and the rotating seat 4, the rotation of the rotating seat 4 will change the relative position between the door panel 2 and the fender 1, thus allowing for adjustments during the processing of the rotating seat 4 and the reinforcing plate 5. When the positioning datum deviates from the design datum, the distance between the rotating seat 4 and the reinforcing plate 5 can be further adjusted by the operator. This makes the adjustable single-axis hinge of the car scissor door highly flexible. After the positioning datum of the rotating seat 4 and the reinforcing plate 5 deviates from the design datum during the processing, the position of the rotating seat 4 can be adjusted to remedy the situation. This helps to reduce the processing accuracy of the rotating seat 4 and the reinforcing plate 5, and can also reduce the gap between the outer wall of the door leaf 2 and the outer wall of the car body fender 1, change the relative position between the door leaf and the car body fender, improve the accuracy of the surface difference and gap between the car door and the car body, thereby improving the flexibility of the device and increasing the aesthetics of the car surface.
[0036] Please refer to Figure 1 and Figure 3 The rotating seat 4 has at least one adjustment hole 42 on the side near the reinforcing plate 5, and the reinforcing plate 5 has a limiting hole 52 that matches the adjustment hole 42 on the side near the rotating seat 4.
[0037] A second bolt 7 is provided on the inner side of the limiting hole 52, which penetrates the rotating seat 4 and the reinforcing plate 5, and the diameter of the second bolt 7 is smaller than the diameter of the limiting hole 52.
[0038] In use, the position and diameter of the limiting hole 52 are the same as those of the adjusting hole 42. When the position of the rotating seat 4 changes, the second bolt 7 is passed through the adjusting hole 42 and the limiting hole 52 and tightened between the rotating seat 4 and the reinforcing plate 5, thereby fixing the rotating seat 4 and the reinforcing plate 5. At the same time, the multiple adjusting holes 42 and the second bolt 7 can increase the stability of the connection between the rotating seat 4 and the reinforcing plate 5. Also, since the diameter of the second bolt 7 is smaller than the diameter of the limiting hole 52, the second bolt 7 can have a certain amount of movement within the limiting hole 52. When the rotating seat 4 rotates around the central axis of the first bolt 6, the position between the adjusting hole 42 and the limiting hole 52 will shift relative to each other. Even after the position between the adjusting hole 42 and the limiting hole 52 shifts, the second bolt 7 can still pass through the adjusting hole 42 and the limiting hole 52 and fix the rotating seat 4 and the reinforcing plate 5.
[0039] Please refer to Figure 6 In Embodiment 2, an arc-shaped groove 10 is provided on the side of the rotating seat 4 near the reinforcing plate 5, and the center of the arc-shaped groove 10 coincides with the central axis of the rotating hole 41. Unlike Embodiment 1, in Embodiment 1, multiple adjustment holes 42 are set as a single arc-shaped groove 10, thereby increasing the rotatable angle of the rotating seat 4. When fine adjustment of the rotating seat 4 is required, the arc-shaped groove 10 can provide greater adjustment freedom compared to multiple adjustment holes 42. By moving the position of the second bolt 7 in the arc-shaped groove 10, the rotating seat 4 can be adjusted within a certain range to meet different installation and use requirements, and has stronger adaptability.
[0040] Please refer to Figure 1 and Figure 3 Multiple connection holes 53 are provided on the side of the reinforcing plate 5 near the fender 1 of the vehicle body;
[0041] In use, multiple fixing bolts 8 are passed through the connecting hole 53 and the body fender 1, and the reinforcing plate 5 is fixed to the body fender 1. To increase the convenience of installation, in one case, the fixing bolts 8 are replaced with screws, and threaded holes are opened at the corresponding positions of the body fender 1 and the connecting hole 53. The screws are screwed into the corresponding threaded holes through the reinforcing plate 5 and the body fender 1 from one side, and the reinforcing plate 5 and the body fender 1 are fixed. However, the fixing method of fixing the fixing bolts 8 and the nuts 61 can increase its stability and can withstand a larger load compared with the screw fixing.
[0042] Please refer to Figure 1 and Figure 4 A reinforcing rib 54 is fixed to the inner side of the reinforcing plate 5, and the reinforcing rib 54 is located between the side wall where the body fender 1 and the rotating seat 4 are in contact.
[0043] In use, the reinforcing plate 5 and the reinforcing rib 54 are fixedly connected, and the reinforcing plate 5 and the reinforcing rib 54 form three mutually perpendicular side walls, forming a three-dimensional support structure. When the support arm 3 and the door leaf 2 rotate, the center of gravity of the door leaf 2 will change. The three-dimensional support structure can provide support for the support arm 3 and the door leaf 2 from multiple directions, reduce local stress concentration, and thus improve the durability and reliability of the structure.
[0044] Please refer to Figure 4 and Figure 5 The rotating seat 4 is fixed with a shaft hole 43 on the side near the support arm 3, and the support arm 3 is provided with a through hole 31 corresponding to the shaft hole 43 near the rotating seat 4, and a single rotating shaft 9 is provided through the inner side of the through hole 31.
[0045] In use, first place the support arm 3 inside the rotating seat 4 and make the central axis of the shaft hole 43 coincide with the central axis of the through hole 31. Then, the single rotating shaft 9 is set to pass through the shaft hole 43 and the through hole 31 in succession, so that the support arm 3 is rotatably connected to the rotating seat 4. At this time, the support arm 3 rotates around the central axis of the single rotating shaft 9, which can drive the door leaf 2 to rotate around the single rotating shaft 9, and drive the door leaf 2 to open and close.
[0046] The following description, in conjunction with the accompanying drawings and embodiments, provides a further explanation of the adjustable single-axis hinge for automobile scissor doors provided by this utility model.
[0047] In use, first, pass multiple fixing bolts 8 through the connecting hole 53 and the body fender 1, and fix the reinforcing plate 5 to the side of the body fender 1. Then, fit one side of the rotating seat 4 against the other side of the reinforcing plate 5, and align the rotating hole 41 on the rotating seat 4 with the fixing hole 51 on the reinforcing plate 5. Simultaneously, pass the first bolt 6 through the rotating hole 41 and the fixing hole 51 from one side of the rotating seat 4 until the end of the first bolt 6 penetrates the reinforcing plate 5. At this point, tighten the nut 61 that matches the first bolt 6 to the end of the first bolt 6. Then, place the support arm 3 inside the rotating seat 4, and align the shaft hole 43 with the central axis of the through hole 31. Then, pass the single rotating shaft 9 through the shaft hole 43 and the through hole 31 in sequence. This allows the support arm 3 to be rotatably connected to the rotating seat 4, and the end of the support arm 3 away from the rotating seat 4 to be fixed to the door leaf 2. When the door leaf 2 is closed, the door leaf 2 is rotated, causing the support arm 3 to rotate around the central axis of the single rotating shaft 9 until the door leaf 2 and the body fender 1 are closed. If the gap between the door leaf 2 and the body fender 1 is too large at this time, the rotating seat 4 is rotated around the second bolt 7 to adjust the distance between the single rotating shaft 9 and the body fender 1, thereby further adjusting the gap between the door leaf 2 and the body fender 1, improving the surface difference and gap accuracy between the car door and the car body, thereby improving the flexibility of the device and increasing the aesthetics of the car surface.
