Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an anti-deviation automotive door guide rail assembly. Background Technology

[0002] In the automotive field, the door rail assembly is a core functional component of the car door system. It is mainly used to guide the movement trajectory of the door and support the door structure. The door rail assembly mainly includes the door hinge rail (such as the sliding door rail) that guides the overall movement of the door, and the special rail that controls the raising and lowering of the window. At the same time, the rail is mainly made of high-strength metal materials (such as stamped steel plates) to bear the weight of the door and dynamic loads.

[0003] Currently, existing automotive door glass guide rail assemblies are mainly connected to the door sheet metal panel and door shell by bolts. However, considering the vibration generated during vehicle operation, the bolts fixing the guide rail assembly are prone to loosening or displacement due to repeated vibrations. This can lead to positional deviation of the guide rail assembly during use, which is not conducive to the normal lifting and lowering of the automotive glass. Therefore, an anti-deviation automotive door guide rail assembly is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-displacement automotive door guide rail assembly to solve the problem mentioned in the background art that, during use, the bolt fasteners of the existing automotive door glass guide rail assembly are easily loosened or displaced due to multiple vibration factors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-deviation automotive door guide rail assembly includes a guide rail stamping body. An upper groove is formed at the upper center of the guide rail stamping body, and a lower groove is formed at the lower center of the guide rail stamping body. Both the lower and upper grooves have limiting screw holes on their inner surfaces. An outer ring is provided around the outer periphery of each limiting screw hole. An inner retaining ring is threaded to the inner side of the outer ring. A limiting guide frame is fixedly connected to the inner surface of the inner retaining ring. A spring is fixedly connected to the inner side of the limiting guide frame. A clamping ring is fixedly connected to the end of the spring. A sliding rod is fixedly connected to the outer surface of the clamping ring. A slider is fixedly connected at the point where the sliding rod abuts against the limiting guide frame. A protrusion is fixedly connected to the inner surface of the clamping ring. Irregularly shaped arc strips are fixedly connected to both the front and rear ends of the outer ring.

[0007] Preferably, the guide rail stamping body is straight, and the guide rail stamping body and the limiting screw holes are integrally formed, with a total of 5 limiting screw holes.

[0008] Preferably, the upper end of the guide rail stamping body is provided with an upper convex plate at the middle position, and the lower end of the guide rail stamping body is provided with a lower convex plate at the middle position. Both the lower convex plate and the upper convex plate are frustum-shaped structures with a central hole.

[0009] Preferably, the plurality of outer rings are respectively disposed on the inner side of the upper groove and the lower groove, and the plurality of outer rings are integrally formed with the guide rail stamping body, and the center point of the outer ring coincides with the center point of the defining screw hole.

[0010] Preferably, there are four groups of sliders, each consisting of two sliders. Each group of sliders is slidably connected to a single limiting guide frame. The connection between the slider and the slide rod forms an "L"-shaped structure. The four clamping rings are arranged in a circular array along the center point of the inner clamping ring. The protrusions are semi-circular in shape, and there are multiple rows of protrusions.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inclusion of an inner retaining ring, a shaped arc strip, a limiting guide frame, a slider, a sliding rod, a clamping ring, a protrusion, and a spring facilitates the rapid connection of this anti-deviation automotive door guide rail assembly to the automotive sheet metal parts and automotive doors via bolt fasteners. To mitigate vibrations generated during vehicle operation, the outer retaining ring, along with the buffer protection structure, provides elastic restraint and buffer protection for the bolt fasteners during vibration. This prevents loosening or displacement due to repeated vibrations and indirectly avoids positional shifts in the stamped parts during use, thus ensuring the proper lifting and lowering of the automotive windows.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution:

[0019] An anti-deviation car door guide rail assembly includes a guide rail stamping body 1. An upper groove 2 is provided at the upper middle position of the guide rail stamping body 1, and a lower groove 3 is provided at the lower middle position of the guide rail stamping body 1. A limiting screw hole 4 is provided on the inner surface of both the lower groove 3 and the upper groove 2. An outer ring 5 is provided on the outer periphery of the limiting screw hole 4. An inner retaining ring 6 is threaded to the inner side of the outer ring 5. A limiting guide frame 8 is fixedly connected to the inner ring surface of the inner retaining ring 6. A spring 13 is fixedly connected to the inner side of the limiting guide frame 8. A clamping ring 11 is fixedly connected to the end of the spring 13. A sliding rod 10 is fixedly connected to the outer ring surface of the clamping ring 11. A slider 9 is fixedly connected at the position where the sliding rod 10 and the limiting guide frame 8 abut. A protrusion 12 is fixedly connected to the inner ring surface of the clamping ring 11. A special-shaped arc strip 7 is fixedly connected to both the front and rear ends of the outer ring 5.

[0020] like Figure 1 As shown, the guide rail stamping body 1 has a straight strip shape. The guide rail stamping body 1 and the limiting screw holes 4 are integrally formed. There are a total of 5 limiting screw holes 4. The multiple limiting screw holes 4 are designed to facilitate multi-point fixing of the stamping part. The upper part of the guide rail stamping body 1 has an upper convex plate 15 at the middle position of the upper end, and the lower part of the guide rail stamping body 1 has a lower convex plate 14 at the middle position of the lower end. Both the lower convex plate 14 and the upper convex plate 15 are frustum-shaped structures with a round hole in the middle. When the glass lifter assembly is installed, the lower convex plate 14 and the upper convex plate 15 are mainly used to fix the lifter wheel.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, multiple outer rings 5 ​​are respectively set inside the upper groove 2 and the lower groove 3. The multiple outer rings 5 ​​are integrally formed with the guide rail stamping body 1. The center point of the outer ring 5 coincides with the center point of the limiting screw hole 4. This structure is conducive to the stamping part accurately installing the buffer protection structure to the outer periphery of the limiting screw hole 4 through the outer rings 5. There are four groups of sliders 9 in pairs. A group of sliders 9 and a single limiting guide frame 8 are slidably connected together. The connection between the slider 9 and the slide rod 10 forms an "L" shaped structure. The four clamping rings 11 are arranged in a ring array structure along the center point of the inner clamping ring 6. The protrusions 12 are semi-circular in shape. There are multiple rows of protrusions 12. When the clamping rings 11 are vibrated and slide slightly, and the spring 13 is squeezed, the sliders 9 and slide rods 10 mainly play an auxiliary limiting and guiding role.

[0022] Workflow: The stamped part in this invention needs to be adapted to automotive sheet metal parts with a multi-hole structure. Before using the anti-deviation automotive door guide assembly, it needs to be installed. With the automotive window regulator pre-assembled onto the stamped part, first firmly grasp the stamped part and insert it into the operating space formed by the automotive sheet metal part and the automotive door. After aligning the multiple limiting screw holes 4 on the stamped part with the multiple holes on the automotive sheet metal part, connect the automotive sheet metal part, the stamped part, and the automotive door together using multiple bolt fasteners to ensure stable lifting and lowering of the automotive window. Simultaneously, before installing the stamped part, it is necessary to connect the inner retaining ring 6 and the... The buffer protection structure, consisting of the arc strip 7, the limiting guide frame 8, the slider 9, the slide rod 10, the clamping ring 11, the protrusion 12, and the spring 13, is assembled to the inner side of the outer ring 5. After the bolt fastener is installed in place, the bolt fastener will be clamped and limited by multiple clamping rings 11. When the stamped part is subjected to vibrations generated by the vehicle operation, the multiple clamping rings 11 will apply the rebound force generated by the compression of the spring 13 to the bolt fastener. Furthermore, the multiple protrusions 12 with anti-slip effect effectively limit and buffer the bolt fastener, preventing it from loosening and slipping outwards. This improves the structural stability of the stamped part during use and avoids displacement problems.
