Description

Technical Field

[0001] This utility model relates to the field of automotive door hinge technology, and in particular to an automotive door hinge assembly with adjustable gap. Background Technology

[0002] As a key component connecting the car door to the body, the performance of the car door hinge directly affects the smoothness of opening and closing, sealing, and driving safety. In the automotive manufacturing and repair field, with the increasing diversification of car models, different models have varying requirements for the installation gap between the door and the body. Simultaneously, during long-term use, frequent opening and closing of the door causes wear on the hinge components due to friction and vibration, leading to a gradual increase in the gap between the door and the body. Traditional car door hinges have a fixed gap, making it difficult to meet the installation needs of different car models and unable to adjust for gap changes caused by wear. When the gap is too large, the door is prone to shaking and abnormal noises during driving, severely affecting the driving experience and reducing the door's sealing, allowing wind, rain, and dust to easily enter the vehicle, affecting interior comfort. Furthermore, an excessively large gap may adversely affect the door locking mechanism, posing a safety hazard. Conversely, a gap that is too small increases the resistance to door opening and closing, accelerates wear on the hinge components, shortens the hinge's lifespan, and may even lead to door deformation or jamming.

[0003] The inventors believe that the following defects often exist: when installing car doors, different door models require different door spacing. At the same time, as the car is used for a long time, frequent opening and closing causes wear and tear, resulting in a larger gap between the door and the car body, causing the door to shake and make abnormal noises, which affects the driving experience and reduces the door's sealing performance. Therefore, in order to address the above problems, an adjustable gap car door hinge assembly is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where frequent opening and closing causes wear, leading to increased gaps between the car door and the car body, door shaking, abnormal noises, and negatively impacting the driving experience and reducing the door's sealing performance. Therefore, this invention proposes an automotive door hinge assembly with adjustable gap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive door hinge assembly with adjustable clearance, comprising a first hinge plate and a second hinge plate, a rotating rod rotatably connected inside the first hinge plate, three rotating grooves being provided on one side of the second hinge plate, the rotating grooves being slidably connected to the arc surface of the rotating rod, three sliding rods being fixedly connected to the surface of the second hinge plate, a third hinge plate being slidably connected to the arc surface of the three sliding rods, three sliding holes being provided on the surface of the third hinge plate, the surfaces of the sliding holes being slidably connected to the arc surface of the rotating rod, a support plate being fixedly connected to the surface of the third hinge plate, a drive rod being threaded into the support plate, a locking block being rotatably connected to one end of the drive rod, two locking slots being provided on the arc surface of the rotating rod, the size of the locking block being adapted to the size of the locking slot of the rotating rod.

[0006] The aforementioned components achieve the following effect: they adjust the gap between the first and second hinge plates, thereby adapting to different door spacings. This avoids the situation where different door models require different door spacings during installation. Additionally, as the car is used over time, frequent opening and closing causes wear and tear, leading to a larger gap between the door and the car body, resulting in door shaking, abnormal noises, and reduced door sealing, thus improving the device's adaptability.

[0007] Preferably, a positioning rod is fixedly connected to the side of the snap-fit ​​block near the drive rod, and the arc surface of the positioning rod is slidably connected to the support plate.

[0008] The effect achieved by the above components is that the positioning rod restricts the locking block from rotating with the drive rod, so as to provide stable and accurate guidance for the locking block.

[0009] Preferably, an anti-slip pad is fixedly connected to one side of the snap-fit ​​block, and a handle is fixedly connected to one end of the drive rod.

[0010] The effects achieved by the above components are as follows: the handle facilitates operation by staff, and the anti-slip pad increases the stability of the locking block within the rotating rod slot.

[0011] Preferably, a rubber ring is fixedly connected to one side of the support plate, and the rubber ring is slidably connected to the arc surface of the drive rod.

[0012] The effect achieved by the above components is that the elasticity of the rubber ring wraps around the drive rod, thereby reducing the impact of external shaking on the drive rod.

[0013] Preferably, one end of the slide bar is fixedly connected to a limit plate.

[0014] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the third hinge plate on the arc surface of the slide rod, thus preventing the third hinge plate from detaching from the arc surface of the slide rod due to excessive pulling force when the operator pulls it.

[0015] Preferably, a first spring is fitted onto the arc surface of the slide rod, and the two ends of the first spring are fixedly connected to the limiting plate and the third hinge plate, respectively.

[0016] The aforementioned components achieve the effect of automatically opening the third hinge plate, thereby reducing the number of steps required for operators to use the device and improving their work efficiency.

[0017] In summary, the beneficial effects of this utility model are as follows: In this invention, the gap between the first hinge plate and the second hinge plate is adjusted through the cooperation of the first hinge plate, the second hinge plate, the third hinge plate, the rotating rod, and the locking block. This achieves the effect of adapting to different door spacings, avoiding the situation where different door models require different door spacings during car door installation. Furthermore, as the car is used over time, frequent opening and closing causes wear, leading to a larger gap between the door and the car body, resulting in door shaking, abnormal noises, and reduced door sealing, thus improving the adaptability of the device.

[0020] Reference Figure 1-5As shown, this utility model provides a technical solution: an automotive door hinge assembly with adjustable clearance, including a first hinge plate 1 and a second hinge plate 2. A rotating rod 4 is rotatably connected inside the first hinge plate 1. Three rotating grooves 5 are opened on one side of the second hinge plate 2, and the rotating grooves 5 are slidably connected to the arc surface of the rotating rod 4. Three sliding rods 7 are fixedly connected to the surface of the second hinge plate 2, and a third hinge plate 3 is slidably connected to the arc surface of the three sliding rods 7. Three sliding holes 6 are opened on the surface of the third hinge plate 3, and the surface of the sliding holes 6 is slidably connected to the arc surface of the rotating rod 4. A support plate 8 is fixedly connected to the surface of the third hinge plate 3, and a drive rod 9 is threaded into the support plate 8. One end of the drive rod 9 is rotatably connected to a locking block 10. Two locking grooves are opened on the arc surface of the rotating rod 4, and the locking block... The size of the locking block 10 is adapted to the size of the slot of the rotating rod 4. When the operator needs to adjust the gap between the first hinge plate 1 and the second hinge plate 2, the drive rod 9 is rotated. The drive rod 9 moves in the thread of the support plate 8, and the drive rod 9 drives the locking block 10 to move until the locking block 10 disengages from the slot of the rotating rod 4. At this time, the third hinge plate 3 is pulled upward, and the third hinge plate 3 slides upward on the arc surface of the slide rod 7. At this time, the position of the rotating rod 4 is adjusted until the correct position is reached. At this time, the third hinge plate 3 is pressed downward, and the third hinge plate 3 slides downward on the arc surface of the slide rod 7 until the surface of the third hinge plate 3 is in contact with the surface of the second hinge plate 2. At this time, the drive rod 9 is rotated again, and the drive rod 9 drives the locking block 10 into the slot of the rotating rod 4. At this time, the gap between the first hinge plate 1 and the second hinge plate 2 is adjusted. The effect of adjusting the gap between the second hinge plate 2 and the door is to adapt to different door spacings, avoiding the need for different door spacings when installing car doors of different models. Furthermore, as the car is used for a longer period, frequent opening and closing causes wear, leading to a larger gap between the door and the body, resulting in door shaking, abnormal noises, and reduced door sealing, thus improving the adaptability of the device. A positioning rod 13 is fixedly connected to the side of the locking block 10 near the drive rod 9. The arc surface of the positioning rod 13 is slidably connected to the support plate 8. Rotating the drive rod 9 causes it to move threadedly within the support plate 8, simultaneously moving the locking block 10. The locking block 10 then causes the positioning rod 13 to slide within the support plate 8. Positioning rod 13 restricts the locking block 10 from rotating with the drive rod 9, providing stable and accurate guidance for the locking block 10. An anti-slip pad 12 is fixedly connected to one side of the locking block 10, and a handle 11 is fixedly connected to one end of the drive rod 9. The handle 11 facilitates operation, while the anti-slip pad 12 increases the stability of the locking block 10 within the slot of the rotating rod 4. A rubber ring 14 is fixedly connected to one side of the support plate 8, slidingly connecting to the arc surface of the drive rod 9. The elasticity of the rubber ring 14 wraps around the drive rod 9, reducing the impact of external shaking on the drive rod 9. A limiting plate 15 is fixedly connected to one end of the slide rod 7, limiting the maximum sliding distance of the third hinge plate 3 on the arc surface of the slide rod 7.To prevent excessive pulling force from causing the third hinge plate 3 to detach from the arc surface of the slide rod 7, a first spring 16 is fitted onto the arc surface of the slide rod 7. The two ends of the first spring 16 are fixedly connected to the limiting plate 15 and the third hinge plate 3, respectively. When the operator releases the locking block 10 from the third hinge plate 3, the rebound force of the first spring 16 causes the third hinge plate 3 to slide upwards on the arc surface of the slide rod 7, achieving the effect of automatically opening the third hinge plate 3. This reduces the number of steps required for operator intervention and improves work efficiency.

[0021] Working principle: When it is necessary to adjust the gap between the first hinge plate 1 and the second hinge plate 2, the operator turns the handle 11, causing the drive rod 9 to move threadedly within the support plate 8. The drive rod 9 pushes the locking block 10 to move away from the rotating rod 4. The positioning rod 13 slides within the support plate 8 to restrict the rotation of the locking block 10, ensuring that it smoothly disengages from the slot of the rotating rod 4. At this time, the rebound force of the first spring 16 causes the third hinge plate 3 to automatically slide upward along the slide rod 7, releasing the restriction on the rotating rod 4. Depending on the door spacing requirements, the rotating rod 4 can be moved to the left or right. The limiting plate 15 restricts the sliding distance of the third hinge plate 3, preventing it from disengaging from the slide rod 7. After adjusting to the appropriate position, press down on the third hinge plate 3 to compress the first spring 16 and make it fit against the second hinge plate 2. Turn the handle 11 again to make the drive rod 9 drive the locking block 10 to insert into the corresponding slot of the rotating rod 4. The anti-slip pad 12 increases the locking stability, and the rubber ring 14 wraps the drive rod 9 with elasticity to reduce the impact of external shaking. Through the above operations, the gap between the first hinge plate 1 and the second hinge plate 2 can be precisely adjusted. It can not only adapt to the installation spacing of different car door models, but also compensate when the gap increases due to wear of the car door. It effectively solves problems such as door shaking, abnormal noise and reduced sealing, and improves the driving experience and device compatibility.
