Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to an adjustable sliding door hinge for automobiles. Background Technology

[0002] Sliding doors for automobiles are widely used in MPVs, SUVs, and other vehicles due to their advantages of large opening space and minimal lateral space occupation. The proper use of sliding doors relies on the precise fit between the hinges, the vehicle body, and the door itself. However, due to minute tolerances in the body panels during automobile manufacturing, or door sagging after prolonged use (due to hinge wear and door weight), the sliding door's vertical position can easily shift, causing interference and jamming during opening and closing, or even preventing normal operation. Existing technologies offer some solutions to these problems. For example, patent CN112049536A discloses a Z-axis adjustment device for an automobile and its sliding door. When adjustment is needed, rotating a threaded component moves the hinge mounting bracket along the axial direction of the threaded component, thus achieving Z-axis adjustment of the sliding door fixedly connected to the hinge mounting bracket. However, this solution relies solely on the friction between the nut and the thread in the Z-axis direction to prevent loosening. High-frequency vibrations during vehicle operation (such as road bumps) and long-term wear can easily cause the nut to loosen, leading to door position shifts, and reliability needs improvement.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] In this embodiment, "several" and "more than" refer to two or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4As shown, this embodiment provides an adjustable sliding door hinge for automobiles, including a connector 1 and a mounting member 2 pivotally connected to the connector 1. The connector 1 is connected to the vehicle body 10, serving as the connection carrier between the hinge and the vehicle body 10, and also providing sliding guidance for the sliding door. The mounting member 2 is connected to the door body 20 of the sliding door, serving as the connection carrier between the hinge and the door body 20. The mounting member 2 is provided with an adjusting plate 3 and a driving member 4. The adjusting plate 3 is locked or fixed to the mounting member 2 by a locking member 5, which can be a screw. The adjusting plate 3 fits against the inner wall of the mounting member 2, increasing the contact area. The locking member 5 passes through the adjusting plate 3 and the mounting member 2 to lock or release with the door body 20, thereby enabling the adjusting plate 3 and the mounting member 2 to be locked onto the door body 20. The side of the adjusting plate 3 is provided with a mating part 31, and the driving member 4 is rotatably connected to the mounting member 2, allowing the driving member 4 to rotate relative to the mounting member 2. The driving component 4 is arranged along the Z-direction and has a driving part 41. The driving part 41 engages with the mating part 31. When the driving component 4 rotates forward or backward, it drives the adjusting plate 3 to rise or fall vertically along the Z-direction. In the above technical solution, when it is necessary to adjust the vertical position of the door body 20, the locking component 5 is first connected to the door body 20 through the adjusting plate 3 and the mounting component 2, but is not locked; then the driving component 4 is rotated to adjust the vertical position of the door body 20. After the adjustment is completed, the locking component 5 is locked. The locking component 5 is used to fix the relative position of the adjusting plate 3 and the mounting component 2 after the adjustment is completed, so as to achieve rigid fixation and avoid loosening during long-term use.

[0026] Specifically, the driving part 41 and the mating part 31 are threadedly engaged, meaning both the mating part 31 and the driving part 41 are threaded. This allows the rotation of the driving member 4 to be converted into the vertical movement of the adjusting plate 3. The threaded engagement also facilitates precise adjustment and engagement. The thread of the mating part 31 is straight, while the thread of the driving part 41 is helical. The driving member 4 can be a bolt. The adjusting plate 3 has a first positioning hole 32, and the mounting member 2 has a second positioning hole 21 corresponding to the first positioning hole 32. The size of the second positioning hole 21 is larger than that of the first positioning hole 32, allowing for a travel distance for the up-and-down movement of the adjusting plate 3. There are at least two first positioning holes 32, located at the corners of the adjusting plate 3. The number of second positioning holes 21 is the same as that of the first positioning holes 32, ensuring a more stable adjusting plate 3 when the locking member is engaged. In this embodiment, the adjusting plate 3 is rectangular.

[0027] Furthermore, the mounting component 2 includes an upper baffle 22, a lower baffle 23, and a mounting plate 24 disposed between the upper and lower baffles, and the mounting component is U-shaped. The adjusting plate 3 is disposed on the mounting plate 24, so that the adjusting plate 3 fits snugly against the mounting plate 24, which can reduce the space occupied by the adjusting plate 3 and make the overall structure more compact. The driving part 41 is located between the upper and lower baffles, and can also limit the adjustment plate 3 through the upper and lower baffles. The driving component 4 is vertically disposed between the upper baffle 22 and the lower baffle 23, and the driving component 4 passes through the holes in the baffles. Bearings can be installed in the holes to make the driving component rotate more flexibly. One end of the connecting component 1 is provided with a roller 11, and the other end is pivotally connected to the mounting component 2 through a shaft 12. The roller 11 cooperates with the sliding track of the vehicle body to realize the lateral sliding of the sliding door and reduce frictional resistance. The driving component 4 is arranged parallel to the shaft 12, so that the transmission direction of the driving component is consistent with the vertical adjustment direction of the door body, avoiding the generation of lateral force during the adjustment process and making the overall hinge structure more stable.

[0028] This embodiment uses the engagement of an adjusting plate and a driving component. The vertical displacement of the adjusting plate is adjusted by rotating the driving component, making the adjustment operation convenient. In addition, the locking component is used to lock the plate perpendicular to the Z-axis, enabling it to withstand Z-axis pressure and improving structural reliability.

[0029] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
