Frameless glass lifter turning adjusting structure

Abstract

This invention discloses a frameless window regulator steering adjustment structure, including a fastening bolt, a mounting base, and a connecting nut. The mounting base has a mounting through hole, and the connecting nut is embedded in and rotatably positioned within the mounting through hole. The fastening bolt extends into the mounting through hole and is threadedly connected to the connecting nut. The connecting nut has a limiting structure that restricts its rotation along the bolt's thread direction with respect to the mounting through hole. Under external force, the fastening bolt swings, causing the connecting nut to rotate within the mounting through hole. Due to the improved overall adjustment structure, the installation position of the adjustment structure on the guide rail is variable, not limited to the position at the upper end of the guide rail as in existing technologies. Therefore, by designing the same length double-ended screw in different positions, the length ratio of L1 to L2 can be effectively improved, thereby increasing the Y-axis preload of the guide rail without lengthening the double-ended screw.

Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a frameless window regulator steering adjustment structure. Background Technology

[0002] Because frameless power windows have a Y-axis pre-compression function, and the compression load of the rubber strips on each door of a real vehicle varies and the state at different times, the pre-compression amount of the power windows needs to be checked and adjusted regularly.

[0003] Traditional frameless lifters require adjusting the height difference between the upper and lower screws and the guide rails during glass pre-compression in the Y direction to adjust the pre-compression amount. However, the adjustment structure currently used by our company and other companies has two drawbacks:

[0004] 1. Adjustment assemblies with Y-axis height adjustment and X-axis rotation can only be installed at the end of the guide rail, such as... Figure 1 As shown, if glass 101, bracket, and guide rail 102 are considered as a lever, with point O1 as the fulcrum and the rotation position of point O2 as S1, then the displacement of glass vertex O3 is S2≈S1*(L1+L2) / L1. The longer L1 is and the shorter L2 is, the more limited the glass adjustment margin will be.

[0005] 2. When installing existing adjustment structures (such as the structure described in patent CN202120160495.X, entitled "A Structure for Y-axis Adjustment of a Window Lifter") with the lifter guide rail, it is necessary to perform flanging on the guide rail and make through holes 103 on two parallel flanges on the guide rail. Then, the elastic pin 104 of the adjustment structure passes through the through holes 103 on the two parallel flanges and the pivot nut of the adjustment structure, and is installed in an interlocking manner (e.g., Figure 2 (As shown).

[0006] Due to structural limitations of existing adjustment mechanisms, the guide rail requires flanging during production, which increases the development cost of guide rail molds and the price of individual guide rails. Furthermore, this adjustment mechanism demands high coaxiality of the two through holes on the two flanged edges of the guide rail. Additionally, because the double-ended screw of the adjustment mechanism can rotate and also rotate around the elastic pin axis at a certain angle, the assembly process of the adjustment mechanism and the guide rail requires special attention to ensure the adjustment of the glass preload. This results in a complex assembly process for the existing adjustment mechanism due to its structural limitations, and long-term maintenance costs for the tooling controlling the through pin shaft are also high. Therefore, it is necessary to provide a new adjustment structure that can not only meet the requirements for glass preload adjustment but also reduce the production cost of the guide rail and the assembly cost of the window regulator. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a frameless window regulator steering adjustment structure that improves the utilization rate of the adjustment screw adjustment range, increases the preload adjustment space, reduces the structural complexity of the regulator guide rail, and reduces the assembly cost of the window regulator.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a frameless window regulator steering adjustment structure, including a fastening bolt, a mounting base, and a connecting nut. The mounting base has a mounting through hole, the connecting nut is embedded in the mounting through hole and rotates within the mounting through hole, the fastening bolt is threaded into the mounting through hole and connected to the connecting nut, the connecting nut has a limiting structure that restricts its rotation and that of the mounting through hole along the rotation direction of the fastening bolt thread, and the fastening bolt swings under external force, causing the connecting nut to rotate within the mounting through hole.

[0009] The principle of this invention: When using the adjustment structure, the mounting base and the guide rail of the lifter are first fixed by welding or riveting. The guide rail has a pre-drilled strip hole (rectangular hole) opposite to the mounting through hole, allowing for fine-tuning after the guide rail is connected to the adjustment structure. Then, the fastening bolt is threaded through the strip hole of the guide rail and into the connecting nut embedded in the mounting through hole. Due to the presence of the limiting structure, the fastening bolt can smoothly rotate and connect with the connecting nut, adjusting the connection amount between the fastening bolt and the connecting nut. Furthermore, the connecting nut can rotate within the mounting through hole, and the fastening bolt is a double-ended screw (as in existing technology). Therefore, rotating the fastening screw changes the preload of the glass lifter, enabling the adjustment structure to achieve the purpose of adjusting the preload of the glass lifter as described in existing technology.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention provides a new adjustment structure that achieves the same function as the adjustment structure in the prior art (patent number CN202120160495.X); however, the adjustment structure of this invention eliminates the need to add a flange structure to the guide rail, thus reducing the manufacturing cost of the guide rail.

[0012] Meanwhile, due to the improvement of the overall structure of the adjustment mechanism, the connection between the mounting base and the guide rail is more convenient, making the overall installation of the lifting device with guide rail faster and saving the installation cost of the lifting device.

[0013] Finally, due to the improvement of the overall adjustment structure, the installation position of the adjustment structure on the guide rail is variable and is not limited to the position at the upper end of the guide rail as in the existing technology. Therefore, by designing the same length double-ended screw in different positions, the length ratio of L1 to L2 can be effectively improved, thereby increasing the Y-direction preload of the guide rail without lengthening the double-ended screw.

[0014] Furthermore, the limiting structure includes two straight sidewalls arranged opposite to each other on the outer periphery of the connecting nut and two outwardly protruding arc-shaped sidewalls arranged opposite to each other, and any straight sidewall is located between the two arc-shaped sidewalls and connected to each other;

[0015] The connecting nut is embedded in the mounting through hole and rotates along the arc direction of the two arc-shaped side walls.

[0016] Furthermore, the inner wall of the mounting through hole is provided with two opposing planar inner walls and two opposing outwardly protruding curved inner walls for use with the limiting structure. Any planar inner wall is located between the two curved inner walls and is connected to each other.

[0017] Furthermore, a guide plane is provided at the junction of the inner wall of any curved surface and the inner walls of the two planes, which is set along the through hole direction of the mounting through hole.

[0018] Furthermore, the connecting nut is detachably connected to the mounting base.

[0019] Furthermore, the mounting base is provided with outwardly extending mounting lugs.

[0020] Furthermore, the number of side ears installed is at least two.

[0021] Furthermore, the diameter of the mounting through hole is larger than the inner diameter of the connecting nut. Attached Figure Description

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] like Figure 3 , 4 As shown in Figure 6, a frameless window regulator steering adjustment structure includes a fastening bolt 1, which is a double-ended screw in the prior art. This structure is the same as the double-ended screw in the prior art (patent number CN202120160495.X), and mainly serves to adjust rotation. Since the fastening bolt 1 needs a certain amount of swing along its connection point with the guide rail 102 during use, this invention provides a new adjustment structure to meet its usage requirements. This adjustment structure includes the fastening bolt 1, a mounting base 2, and a connecting nut 3. The mounting base 2 has a mounting through hole 25, and the connecting nut 3 is embedded in the mounting through hole 25 and rotates within it. The fastening bolt 1 is threaded into the mounting through hole 25 and connected to the connecting nut 3. The connecting nut 3 has a limiting structure that restricts its rotation and that of the mounting through hole 25 along the direction of the fastening bolt 1's thread rotation. Furthermore, the fastening bolt 1 swings under external force, causing the connecting nut 3 to rotate within the mounting through hole 25.

[0037] To ensure that the connecting nut 3 can be fitted into and rotate within the mounting through hole 25, and also to prevent the connecting nut 3 from rotating within the mounting through hole 25 in that direction when it is rotatably connected to the fastening bolt 1, this invention provides a connecting nut 3 structure that achieves the above-mentioned effects. For example... Figure 2 ,3 As shown in Figure 4, the external structure of the connecting nut 3 is roughly hemispherical (e.g., ...). Figure 7 As shown in (1), of course, the shape of the connecting nut 3 is not limited to a hemispherical shape, but can also be a rotatable semi-cylindrical shape (such as...). Figure 7 As shown in (2), as long as the connecting nut 3 can rotate in a specific direction within the mounting through hole 25, and the connecting nut 3 does not rotate within the mounting through hole 25 when the fastening bolt 1 is rotatably connected to the connecting nut 3, it is sufficient. Based on the structure of the connecting nut 3 in this embodiment, the outer periphery of the connecting nut 3 includes two oppositely arranged straight sidewalls 32 and two oppositely arranged outwardly protruding arc-shaped sidewalls 31, and any straight sidewall 32 is located between and connected to the two arc-shaped sidewalls 31. The two straight sidewalls 32 on the connecting nut 3 can limit the rotation direction of the connecting nut 3, preventing the connecting nut 3 from rotating within the mounting through hole 25 when the fastening bolt 1 is rotatably connected to the connecting nut 3, while the two arc-shaped sidewalls 31 can cause the fastening bolt 1 to be subjected to external force, thereby driving the connecting nut 3 to rotate within the mounting through hole 25 along the arc-shaped direction of the arc-shaped sidewall 31, achieving the function of the adjustment structure in the prior art. Of course, the overall shape of the arc-shaped sidewall 31 can also be hemispherical or semi-cylindrical. The purpose is simply to ensure that the arc-shaped sidewall 31 can rotate in a preset direction when it comes into partial contact with the interior of the mounting through hole 25.

[0038] To ensure that the mounting through hole 25 can both accommodate the connecting nut 3 and allow the connecting nut 3 to rotate or be braked within the mounting through hole 25 as needed, this invention provides a mounting through hole 25 structure that matches the structure of the connecting nut 3, such as... Figure 4 , 5 As shown, the inner wall of the mounting through hole 25 is provided with two opposing planar inner walls 24 and two opposing outwardly protruding curved inner walls 22 for use with the limiting structure. Each planar inner wall 24 is located between and connected to the two curved inner walls 22. When the connecting nut 3 is embedded in the mounting through hole 25, the two straight sidewalls 32 of the connecting nut 3 fit precisely with the two planar inner walls 24 within the mounting through hole 25, while the two arc-shaped sidewalls 31 of the connecting nut 3 cooperate with the two curved inner walls 22 of the mounting through hole 25. In this structure, the mounting through hole 25 and the connecting nut 3 allow the connecting nut 3 and the mounting through hole 25 to remain essentially unchanged during the bolting process of the fastening bolt 1 rotating and the bolting connection of the connecting nut 3, thus achieving the braking effect of the connecting nut 3. This allows the fastening bolt 1 to be rotated to adjust the preload. Furthermore, the cooperation between the curved inner wall 22 of the mounting through hole 25 and the arc-shaped side wall 31 of the connecting nut 3 allows the connecting nut 3 to rotate within the mounting through hole 25 when the fastening bolt 1 swings along its axial direction, achieving the desired installation purpose.

[0039] The curved inner wall 22 of the mounting hole 25 and the arc-shaped side wall 31 of the connecting nut 3 not only effectively provide the connecting nut 3 with the function of rotating up and down, but also effectively increase the contact area between the connecting nut 3 and the inner wall of the mounting hole 25, thereby increasing the force transmission effect and improving stability. The fit between the two straight side walls 32 of the connecting nut 3 and the two planar inner walls 24 of the mounting hole 25 effectively prevents the connecting nut 3 from rotating along the axial direction of the fastening bolt 1. Without this structural design, the connecting nut 3 would rotate with the fastening bolt 1. Furthermore, the external structure of the mounting hole 25 can be arbitrarily set, as long as the internal structure of the mounting hole 25 matches the external structure of the connecting nut 3.

[0040] In summary, considering the structure of the mounting through hole 25 and the connecting nut 3, the principle of this invention is as follows:

[0041] When using the adjustment structure, first fix the mounting base 2 to the guide rail 102 of the lifter by welding or riveting. The guide rail 102 has a pre-drilled strip hole (rectangular hole) opposite to the mounting through hole 25 to allow for fine adjustment after the guide rail 102 is connected to the adjustment structure. Then, the fastening bolt 1 is threaded through the strip hole of the guide rail 102 and connected to the connecting nut 3 embedded in the mounting through hole 25. Due to the existence of the limiting structure, the fastening bolt 1 can be smoothly rotated and connected to the connecting nut 3, and the connection amount between the fastening bolt 1 and the connecting nut 3 can be adjusted. In addition, the connecting nut 3 can rotate within the mounting through hole 25, and the preload of the glass lifter can be changed by rotating the fastening screw, so that the adjustment structure achieves the purpose of adjusting the preload of the glass lifter in the prior art.

[0042] This invention provides a new adjustment structure. While still achieving the adjustment function, the improvement of the overall structure of the adjustment structure eliminates the need to add a flange structure to the guide rail 102, thereby reducing the manufacturing cost of the guide rail 102.

[0043] Meanwhile, due to the improvement of the overall structure of the adjustment mechanism, the connection between the mounting base 2 and the guide rail 102 is more convenient, making the overall installation of the lifter containing the guide rail 102 faster and saving the installation cost of the lifter.

[0044] Finally, due to the improvement in the overall adjustment structure, the installation position of the adjustment structure on the guide rail 102 is variable, and it is not limited to the position at the upper end of the guide rail 102 as in the prior art. Therefore, by designing double-ended screws of the same length in different positions, the overall performance can be effectively improved. Figure 1 The length ratio of L1 to L2 is adjusted to increase the Y-direction preload of guide rail 102 without lengthening the double-ended screw.

[0045] Furthermore, in order to facilitate the rotation of the connecting nut 3 within the mounting through hole 25 under the action of the fastening bolt 1, the diameter of the mounting through hole 25 provided in this invention is necessarily larger than the inner diameter of the connecting nut 3, so that the fastening bolt 1 connected to the connecting nut 3 also has sufficient room for swing.

[0046] Furthermore, to facilitate the manufacturing and processing of the mounting base 2 and the connecting nut 3, the present invention makes the connecting nut 3 detachably connected to the mounting base 2. For example... Figure 3 , 4 As shown in Figure 5, specifically, since the connecting nut 3 can rotate along the arcuate direction of its two arcuate sidewalls 31 within the mounting through hole 25; when the connecting nut 3 is not connected to the fastening bolt 1, the connecting nut 3 can rotate until its arcuate sidewalls 31 are located at the opening position of the mounting through hole 25 (i.e., Figure 3 (The connecting nut 3 is rotated 90° around the view direction), and then external force can be used to remove the connecting nut 3 from the mounting through hole 25; when it is necessary to connect the connecting nut 3 to the mounting through hole 25, simply reverse the operation to place the connecting nut 3 into the mounting through hole 25. Figure 3 As shown, the fastening screw passes through the slotted hole in the guide rail 102 and extends into the mounting through hole 25 to connect with the connecting nut 3 via a thread. Therefore, based on the structure of the connecting nut 3 and the mounting through hole 25, the connecting nut 3 can be detachably connected to the mounting through hole 25, allowing for separate manufacturing processes and reducing the manufacturing difficulty of the mounting base 2 and the connecting nut 3. Furthermore, the assembly process of the connecting nut 3 and the mounting through hole 25 is extremely simple and convenient, improving the assembly efficiency of the lifting device assembly.

[0047] Furthermore, to ensure the connecting nut 3 can be smoothly inserted into the mounting through hole 25, and to facilitate the insertion process of the connecting nut 3, a guide plane 24 is provided at the junction of any curved inner wall 22 and the two planar inner walls 24 within the mounting through hole 25, arranged along the through hole direction of the mounting through hole 25. For example... Figure 4 , 5 As shown, four guide planes 24 are provided at each end of the mounting through hole 25. These four guide planes 24 extend into the mounting through hole 25 and are designed with a certain angle for guidance, ensuring that the connecting nut 3 inserted into the mounting through hole 25 along the guide planes 24 can smoothly enter. Specifically, this can be understood as follows: the four guide planes 24 at each end of the mounting through hole 25 are inclined in a contracting state from the outside of the mounting through hole 25 towards the inside; or, the four guide planes 24 at each end of the mounting through hole 25 are inclined in a expanding state from the inside of the mounting through hole 25 towards the outside. The guide planes 24 serve both to guide the connecting nut 3 during insertion and to avoid obstructing its rotation. Without this design structure, the connecting nut 3 would not be able to penetrate the base.

[0048] Furthermore, since the mounting base 2 is directly fixedly connected to the guide rail 102, to facilitate the fixing of the mounting base 2 to the guide rail 102, the present invention provides outwardly extending mounting ears 21 on the mounting base 2. The number of mounting ears 21 can be one or more. The mounting position of the mounting ears 21 can be set according to requirements, and its main purpose is to facilitate the fixed connection of the entire mounting base 2 to the guide rail 102.

[0049] To ensure that the mounting lug 21 can be fitted and fixed to the guide rail 102, in this embodiment, the mounting lug 21 extends outward along any open end of the mounting through hole 25 and is flush with the open end of the mounting through hole 25. For example... Figure 4 , 5 As shown, the mounting ear 21 is fitted to the guide rail 102. Depending on the method of fixing the mounting ear 21 to the guide rail 102, a rivet hole can be made on the mounting ear 21 to facilitate the riveting and fixing of the mounting ear 21 to the guide rail 102; or, it is not necessary to make a rivet hole on the mounting ear 21, and the mounting ear 21 to the guide rail 102 can be fixed directly by welding, so as to achieve the fixing of the mounting base 2, the mounting through hole 25 and the guide rail 102.

[0050] Of course, in some special cases, the guide rail 102 is not a horizontal plane; in this case, the mounting side ear 21 can be set to extend outward close to the opening end of the mounting through hole 25, and can be offset at a certain angle along the opening end of the mounting through hole 25; or the mounting side ear 21 can be a certain distance from the opening end of the mounting through hole 25; as long as the mounting position of the mounting side ear 21 and the mounting through hole 25 can match the structure of the guide rail 102, the entire mounting base 2 can be fixed to the guide rail 102 after the mounting side ear 21 is fixed to the guide rail 102.

[0051] Furthermore, to ensure a stable connection between the mounting base 2 and the guide rail 102, the number of mounting lugs 21 can be 2, 3, 4, 6, etc. Providing at least two mounting lugs 21 can distribute the force when the mounting lugs 21 are connected to the guide rail 102, increasing the stability of the connection and extending the service life of the entire adjustment structure. The positions of the multiple mounting lugs 21 can be set according to requirements to ensure that the entire mounting base 2 meets the force requirements after being connected to the guide rail 102. In this embodiment, as... Figure 4 , 5 As shown, there are two mounting ears 21, which extend outwards from the opening end of the mounting through hole 25. The two mounting ears 21 can also be positioned as follows: Figure 5 The mounting hole 25 is rotated 90° along its through-hole direction (i.e., it extends outward along the outer side of the inner wall of the two curved surfaces of the mounting hole 25).

[0052] To further define the interrelationships of the various components of the adjustment structure in this invention, the following aspects will be considered.

[0053] 1. Reference Figure 7 , 9 As shown in Figure 11, the length by which the connecting nut 3 extends beyond the mounting through hole 25 when it is embedded in the mounting through hole 25 is limited to b (the extension at each end is b); the radius of the sphere corresponding to the curved inner wall 22 of the mounting through hole 25 is limited to R, and the curvature angle of the inner wall 22 is limited to α; at the same time, the length of the entire connecting nut 3 is limited to L. Then b, R, α, and L satisfy the formula: Sin(α / 2)*R=(L / 2)-b; where b, R, and L are variables, and the angle α is determined by the first three variables.

[0054] 2. The design of the guide plane 23 is based on the fact that the overall structure of the connecting nut 3 is roughly hemispherical. Figure 4 (structure in the text), such as Figure 11 As shown, based on the hemispherical connecting nut 3, the guide plane 23 extends into the mounting through hole 25 with a width L1 ≥ 1mm. In this embodiment, the guide plane 23 extends into the mounting through hole 25 with a width of 1mm. If the overall structure of the connecting nut 3 is approximately semi-cylindrical (e.g. Figure 7 As shown in (2), there is no need to set a guide plane 23 in the mounting through hole 25.

[0055] 3. To ensure that the connecting nut 3 can be smoothly rotated into or removed from the mounting through hole 25, as follows: Figure 8 , 10 As shown in Figure 12, at any end of the mounting through hole 25, the distance L2 between the two guide planes 23 along the length direction perpendicular to the mounting through hole 25 is equal to the depth of the thread in the connecting nut 3 (also known as the length of the connecting nut 3) L.

[0056] If connecting nut 3 is used Figure 7 In the hemispherical structure of (1), the length of the distance C between the inner walls 24 of the two planes inside the mounting hole 25 satisfies If connecting nut 3 is used Figure 7 The structure in (2) is roughly semi-cylindrical. Therefore, the length of the distance C' between the inner walls 24 of the two planes within the mounting hole 25 of this structure must satisfy the following condition:

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
