Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, and in particular to a window regulator adjuster. Background Technology
[0002] The raising and lowering of automotive windows is achieved by a specialized lift mechanism that uses steel cables to move the glass up or down. During repeated raising and lowering movements, the steel cables are under constant tension, causing their free length to gradually increase. When this elongation reaches a certain point, there will be a gap in the cable's travel, preventing the glass from moving to its original maximum position. This is especially problematic for frameless windows; if the glass cannot reach its highest point, issues such as leaks and air inconsistencies may occur. Therefore, it is necessary to compensate for the elongation of the steel cables to ensure the proper functioning of the window lift mechanism. Utility Model Content
[0003] The purpose of this utility model is to provide a glass lift adjuster to solve the problems mentioned in the background art, automatically compensate for the elongation of the wire rope, and ensure the tension of the wire rope.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A window lift adjuster includes a socket, a first automatic adjustment cover, a second automatic adjustment cover, and a compensating spring, wherein:
[0006] The outer wall of the socket is provided with several circumferential teeth, and each circumferential tooth is arranged at equal intervals along the axial direction of the socket. One end of the socket is provided with a socket hole.
[0007] The first automatic adjustment cover is fitted onto the socket, and a guide tube for inserting into the socket is provided inside the first automatic adjustment cover. The guide tube is used to pass through the regulator wire rope. A first stop is provided on the end of the first automatic adjustment cover away from the socket.
[0008] The second automatic adjustment cover is fitted onto the first automatic adjustment cover and abuts against the first stop edge. The second automatic adjustment cover is provided with a first claw. After the first claw passes through the first automatic adjustment cover, it engages with any circumferential claw tooth. The second automatic adjustment cover is provided with a second stop edge at one end near the socket.
[0009] The compensating spring is sleeved on the socket and abuts against the second stop. The compensating spring is used to give the second automatic adjustment cover and the first automatic adjustment cover a force away from the socket, thereby ensuring the tension of the regulator wire rope.
[0010] As an alternative, the circumferential surface of the second automatic adjustment cover is provided with a U-shaped groove, the first claw is formed by the middle part of the U-shaped groove, and the end of the first claw is bent inward.
[0011] As an alternative, the surface of the first claw is provided with reinforcing ribs.
[0012] As an optional solution, three first jaws are provided, and the three first jaws are evenly distributed around the circumference.
[0013] As an alternative, the bent first claw limits the position of the first automatic adjustment cover near the socket.
[0014] As an alternative, a locking groove is provided circumferentially on the outer wall of the socket, and a notch is provided on the locking groove; a second claw is provided on the second automatic adjustment cover.
[0015] When the second claw engages in the locking slot, the axial displacement of the second automatic adjustment cover relative to the socket is locked.
[0016] When the second automatic adjustment cover rotates relative to the socket until the second pawl is in the notch, the second automatic adjustment cover can move axially relative to the socket.
[0017] As an optional solution, the socket is marked with a first arrow corresponding to the notch, and the second automatic adjustment cover is marked with a second arrow corresponding to the second claw.
[0018] When the second arrow is aligned with the first arrow, the second claw is located at the notch.
[0019] As an optional solution, three second jaws are provided, which are evenly distributed around the circumference and are staggered from the first jaws.
[0020] As an alternative, the surface of the first automatic adjustment cover is provided with a protruding ridge along its own axis, and the inner wall of the second automatic adjustment cover is provided with a positioning groove corresponding to the protruding ridge. The protruding ridge and the positioning groove cooperate so that the first automatic adjustment cover and the second automatic adjustment cover can only move relative to each other axially.
[0021] As an alternative, the surface of the first automatic adjustment cover is provided with positioning protrusions, and the inner wall of the second automatic adjustment cover is provided with cavities corresponding to the positioning protrusions.
[0022] The beneficial effects of this utility model are:
[0023] During operation, the adjusting wire rope of this window lift mechanism passes through the first automatic adjusting cover, the second automatic adjusting cover, and the socket. Initially, the tension of the adjusting wire rope compresses the compensating spring. When the elongation of the adjusting wire rope reaches a certain value, the tension decreases, and the elastic force of the compensating spring pushes the first and second automatic adjusting covers away from the socket. This allows the elongated portion of the adjusting wire rope to be absorbed by the window lift mechanism, thus ensuring the tension of the adjusting wire rope is always maintained, allowing the glass to always rise to its highest point and preventing issues such as the vehicle body not being sealed properly or air leakage.

[0039] Please see Figures 1 to 5 As shown, this embodiment provides a window lift adjuster, including a socket 1, a first automatic adjustment cover 2, a second automatic adjustment cover 3, and a compensating spring 4, wherein:
[0040] The outer wall of the socket 1 is provided with a number of circumferential teeth 11, and each circumferential tooth 11 is arranged at equal intervals along the axial direction of the socket 1. One end of the socket 1 is provided with a socket 12.
[0041] The first automatic adjustment cover 2 is fitted onto the socket 1, and the first automatic adjustment cover 2 is provided with a guide tube 21 for inserting into the socket 12. The guide tube 21 is used to pass through the regulator wire rope. The first automatic adjustment cover 2 is provided with a first stop 22 at the end away from the socket 1.
[0042] The second automatic adjustment cover 3 is fitted onto the first automatic adjustment cover 2 and abuts against the first stop edge 22. The second automatic adjustment cover 3 is provided with a first claw 31. After the first claw 31 passes through the first automatic adjustment cover 2, it engages with any circumferential claw 11. The second automatic adjustment cover 3 is provided with a second stop edge 32 at one end near the socket 1.
[0043] The compensating spring 4 is sleeved on the socket 1 and abuts against the second stop 32. The compensating spring 4 is used to give the second automatic adjustment cover 3 and the first automatic adjustment cover 2 a force away from the socket 1, thereby ensuring the tension of the regulator wire rope.
[0044] During use, the regulator wire rope passes through the first automatic adjustment cover 2, the second automatic adjustment cover 3, and the socket 1. Therefore, in the initial state, the tension of the regulator wire rope compresses the compensating spring 4. (See details...) Figure 1 When the elongation of the regulator wire rope reaches a certain value, the tension of the regulator wire rope decreases, and the elastic force of the compensating spring 4 pushes the first automatic adjustment cover 2 and the second automatic adjustment cover 3 away from the socket 1. See details. Figure 2 Until the first pawl 31 engages with a certain circumferential tooth 11, the tension returns to its original value, so that the elongated part of the regulator wire rope is eliminated and absorbed by the window lift regulator, thereby always ensuring the tension of the regulator wire rope, so that the glass can always rise to the highest point, avoiding situations such as the vehicle body not being sealed or air leakage.
[0045] The pre-compression of the compensation spring 4 is precisely calculated to provide sufficient elastic force while avoiding fatigue failure caused by excessive compression.
[0046] Optionally, a U-shaped groove 33 is provided on the circumferential surface of the second automatic adjustment cover 3, and the first claw 31 is formed by the middle part of the U-shaped groove 33, and the end of the first claw 31 is bent inward.
[0047] This facilitates the simple forming of the first claw 31 on the second automatic adjustment cover 3, simplifies the structure and manufacturing process of the second automatic adjustment cover 3, and the design of the U-shaped groove 33 makes the first claw 31 more flexible, enhancing the stability and durability of the clamping.
[0048] Furthermore, the surface of the first claw 31 is provided with reinforcing ribs 34. The presence of reinforcing ribs 34 not only improves the strength of the first claw 31, but also further enhances the reliability of the engagement, effectively preventing loosening caused by external forces.
[0049] Optionally, three first jaws 31 are provided, and the three first jaws 31 are evenly distributed around the circumference. The design of the three first jaws 31 being evenly distributed around the circumference ensures reliable engagement and guarantees the stability of the positions of the second automatic adjustment and the first automatic adjustment cover 2.
[0050] Furthermore, the bent first claw 31 limits the position of the first automatic adjustment cover 2 near the socket 1. The bent design of the first claw 31 not only meets the requirement of engaging the circumferential teeth 11 inward, but also effectively prevents the first automatic adjustment cover 2 from moving excessively, so that the first automatic adjustment cover 2 and the second automatic adjustment cover 3 are combined into a whole.
[0051] Optionally, a locking groove 13 is provided circumferentially on the outer wall of the socket 1, and a notch 14 is provided on the locking groove 13. A second claw 35 is provided on the second automatic adjustment cover 3.
[0052] When the second claw 35 is engaged in the locking groove 13, the axial displacement of the second automatic adjustment cover 3 relative to the socket 1 is locked.
[0053] When the second automatic adjustment cover 3 rotates relative to the socket 1 until the second claw 35 is located at the notch 14, the second automatic adjustment cover 3 can move axially relative to the socket 1.
[0054] Thus, by changing the position of the second claw 35, the second automatic adjustment cover 3 can be flexibly switched between the locked state and the movable state, ensuring structural stability and normal compensation function in the factory condition.
[0055] Furthermore, the socket 1 is marked with a first arrow 15 at the position corresponding to the notch 14, and the second automatic adjustment cover 3 is marked with a second arrow 36 at the position corresponding to the second claw 35;
[0056] When the second arrow 36 is aligned with the first arrow 15, the second claw 35 is located at the notch 14.
[0057] This allows users to quickly identify and adjust the position of the second automatic adjustment cover 3, ensuring accurate and efficient operation.
[0058] Optionally, three second claws 35 are also provided, with the three second claws 35 evenly distributed around the circumference, and the second claws 35 are staggered from the first claw 31.
[0059] This avoids mutual interference between the first claw 31 and the second claw 35, making the structure of the second automatic adjustment cover 3 more stable and reasonable.
[0060] Optionally, the surface of the first automatic adjustment cover 2 is provided with a protruding ridge 23 along its own axial direction, and the inner wall of the second automatic adjustment cover 3 is provided with a positioning groove 37 corresponding to the protruding ridge 23. The protruding ridge 23 and the positioning groove 37 cooperate so that the first automatic adjustment cover 2 and the second automatic adjustment cover 3 can only move relative to each other axially.
[0061] This ensures that the first automatic adjustment cover 2 and the second automatic adjustment cover 3 are precisely aligned during axial movement, avoiding radial offset and improving the compactness and stability of the overall structure.
[0062] Optionally, the surface of the first automatic adjustment cover 2 is provided with a positioning protrusion 24, and the inner wall of the second automatic adjustment cover 3 is provided with a cavity 38 corresponding to the positioning protrusion 24.
[0063] Under normal circumstances, there is no relative displacement between the first automatic adjustment cover 2 and the second automatic adjustment cover 3. The positioning protrusion 24 and the cavity 38 are precisely matched, which further enhances the matching effect of the first automatic adjustment cover 2 and the second automatic adjustment cover 3, prevents accidental misalignment, and ensures that the adjustment process is stable and reliable.
[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
