Description

Technical Field

[0001] This utility model relates to the field of automotive window regulator technology, specifically to a connection structure for an automotive window regulator drive mechanism. Background Technology

[0002] A window regulator is a device for raising and lowering automotive door windows. For example, a motor bracket connection structure for an automotive window regulator, disclosed in publication number "CN222558362U," includes a positioning assembly comprising a positioning plate one and a positioning plate two. A limit plate is provided on one side of the positioning assembly, and a hydraulic rod is provided on one side of the positioning plate one. A sliding plate is fixedly installed at the telescopic end of the hydraulic rod, and a clamping plate one is rotatably installed at one end of the sliding plate. The positioning plate one is rotatably installed at one end of the positioning plate one. This automotive window regulator motor bracket connection structure, through the inclusion of a hydraulic rod and sliding wheels, allows the hydraulic rod to move the sliding plate, indirectly causing the clamping plates one and two to rotate. The movement of clamping plates one and two adjusts the position of the glass. The sliding wheels further limit the movement of clamping plates one and two by embedding them into a sliding groove two, preventing clamping plate two from easily detaching from the positioning plate two. Simultaneously, the clamping plates one and two are positioned in real-time using locking strips during movement, making the movement of clamping plates one and two more stable and effectively improving the stability of window raising and lowering.

[0003] However, the sliding wheel and the groove in the above document lack a dustproof design, which makes it easy for dust to enter, thus causing jamming problems during use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a connection structure for the drive mechanism of an automotive window regulator that can improve sealing performance and thus avoid jamming, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a driving mechanism of an automotive window regulator, comprising a positioning plate one and a positioning plate two for glass installation, wherein a linkage assembly is provided between the positioning plate one and the positioning plate two, a hydraulic rod is provided on one side of the positioning plate one, and a linkage member is provided between the output end of the hydraulic rod and the linkage assembly, wherein the hydraulic rod can drive the linkage member to reciprocate, thereby linking the linkage assembly to cause the positioning plate two to rise or fall, characterized in that: a first pulley group is rotatably provided at the lower end of the linkage member, a first sliding groove is provided on the positioning plate one for the first pulley group to slide, a first sealing groove is provided along the inner wall of the first sliding groove, and a first lip sealing strip is embedded in the first sealing groove, the first lip sealing strip being able to fit tightly with the first pulley group.

[0006] The above technical solution, compared with the existing technology which has no dustproof design between the sliding wheel and the slide groove, improves the sealing performance by providing a first sealing groove on the inner wall of the first slide groove and embedding a first lip-shaped sealing strip in the first sealing groove, so that the first lip-shaped sealing strip can fit tightly with the first pulley assembly, preventing dust and other foreign objects from falling between the first pulley assembly and the first lip-shaped sealing strip.

[0007] A further feature of this invention is that the first lip-shaped sealing strip includes two sets of first lips with inner protrusions, and a first groove is formed between the first lips; the first pulley group includes at least one set of first sliding wheels arranged opposite each other, the first sliding wheels are connected by a first rotating shaft, a first bushing is provided outside the first rotating shaft, a first annular groove is provided on the outer wall of the first bushing, a first sealing ring is embedded in the first annular groove, and the outer side of the first sealing ring can move within the first groove and seal with the first lip.

[0008] The above technical solution involves the setting of the first lip on the first lip-shaped sealing strip and the first sealing ring on the first bushing. When the first sliding wheel moves along the first groove, the first sealing ring is located in the first groove. Due to the elastic properties of the lip, it will tightly adhere to the surface of the first sealing ring, forming a sealing barrier. In addition to the area where the first sliding wheel is located, the first lip of the first lip-shaped sealing strip will cover the first groove, preventing dust from falling into the first groove and improving the sealing performance. Preferably, lubricating oil can be applied to the first groove, so that when the first sliding wheel slides, the first sealing ring slides more smoothly in the first groove. At the same time, when the first sliding wheel rolls, the contact point between the first lip and the first sealing ring forms a shearing force, which can peel off the dust attached to the outside of the first sealing ring from the surface.

[0009] A further feature of this invention is that the linkage includes a first sliding plate and a second sliding plate, the first sliding plate and the second sliding plate are respectively located on both sides of the positioning plate, and the two ends of the first rotating shaft are respectively rotatably connected to the first sliding plate and the second sliding plate. The top ends of the first sliding plate and the second sliding plate are connected by a connecting shaft, and the two ends of the connecting shaft are rotatably connected to the connecting rod assembly. One side of the first sliding plate is connected to the hydraulic rod output end.

[0010] The above technical solution is adopted as follows: With the setting of the first slide plate and the second slide plate, during use, the first slide plate is moved by activating the hydraulic rod. Since the first slide plate and the second slide plate are connected by the connecting shaft and the first rotating shaft, the first slide plate can drive the second slide plate to move together, thereby linking the linkage assembly and driving the positioning plate two to rise and fall.

[0011] A further feature of this invention is that the connecting rod assembly includes two sets of clamping plates 1 arranged opposite to each other and two sets of clamping plates 2 hinged to the middle of clamping plates 1, and the two are arranged in a cross shape. The clamping plates 1 are rotatably mounted on the end of the connecting shaft, and the clamping plates 2 are rotatably connected to the end of the positioning plate 1 away from the first sliding plate. The other end of the clamping plates 1 is rotatably provided with a second pulley group, and the other end of the clamping plates 2 is rotatably provided with a third sliding wheel. The positioning plate 2 is provided with a second sliding groove for the second pulley group and the third sliding wheel to slide.

[0012] The above technical solution employs two clamping plates: a first clamp and a second clamp. The position of the glass is adjusted using clamps one and two, and the angle between them is adjusted to raise and lower the glass. The cross-clamping of clamps one and two increases the stability and balance of the lifting structure, reduces tilting and instability, and minimizes uneven stress and deformation. Therefore, the cross-clamping of clamps one and two provides greater stability during glass raising and lowering.

[0013] A further feature of this invention is that a second sealing groove is provided along the inner wall of the second sliding groove, and a second lip-shaped sealing strip is embedded in the second sealing groove, which can fit tightly with the second pulley assembly.

[0014] The above technical solution is adopted: by providing a second sealing groove on the inner wall of the second slide groove, and embedding a second lip-shaped sealing strip in the second sealing groove, the second lip-shaped sealing strip can fit tightly with the second pulley group and the third sliding wheel, preventing dust and other foreign objects from falling into the interior and improving the sealing performance.

[0015] A further feature of this invention is that the second lip-shaped sealing strip includes two sets of second lips with inner protrusions, and a second groove is formed between the second lips; the second pulley group includes a set of second sliding wheels arranged opposite to each other, the second sliding wheels are connected by a second rotating shaft, a second bushing is provided outside the second rotating shaft, a second annular groove is provided on the outer wall of the second bushing, a second sealing ring is embedded in the second annular groove, and the outer side of the second sealing ring can move within the second groove and seal with the second lip.

[0016] The above technical solution involves setting a second lip on the second lip-shaped sealing strip and a second sealing ring on the second bushing. When the second sliding wheel moves along the second groove, the second sealing ring is located in the second groove. Due to the elastic properties of the lip, it will tightly adhere to the surface of the second sealing ring, forming a sealing barrier. In addition to the area where the second sliding wheel is located, the second lip of the second lip-shaped sealing strip will cover the second groove, preventing dust from falling into the second groove and further improving the sealing performance. Preferably, lubricating oil can be applied to the second groove, so that the second sealing ring slides more smoothly in the second groove when the second sliding wheel slides.

[0017] A further feature of this invention is that: a third rotating shaft is provided in the middle of the third sliding wheel, and the two ends of the third rotating shaft are rotatably connected to each clamping plate; a third annular groove is provided along the circumferential direction of the outer wall of the third sliding wheel; the third annular groove can be embedded in the interior of the second sliding groove; a third sealing groove is provided on the outer wall of the third annular groove; a third sealing ring is embedded in the third sealing groove; the outer side of the third sealing ring can move within the second groove and seal with the second lip.

[0018] The above technical solution is adopted: by setting the third sealing ring on the third sliding wheel, when the third sliding wheel moves along the second sliding groove, the third sealing ring is located in the second groove. Due to the elastic properties of the lip, it will tightly fit the surface of the third sealing ring, forming a sealing barrier. In addition, the second lip of the second lip sealing strip will cover the second groove in the area where the third sliding wheel is located, preventing dust from falling into the second groove and further improving the sealing performance.

[0019] A further feature of this invention is that the upper end of the positioning plate has an integrally formed mounting part for glass installation, the upper end of the mounting part has an installation groove, and a number of mounting holes are provided through the mounting part from one side to the other side, with the mounting holes arranged at intervals along the transverse direction of the mounting part.

[0020] The above technical solution facilitates the installation of glass by setting up mounting slots and mounting holes. After the glass is placed into the mounting slot and the mounting holes on the glass are aligned with the mounting holes on the mounting part, the fasteners are inserted to complete the installation of the glass.
