Technical Field
The invention relates to the technical field of automobile parts, in particular to a steering adjusting structure of a frameless glass lifter.
Background
Because the frameless glass lifter has a Y-direction pre-pressing function, the compression load of the adhesive tape of each door on the real vehicle and the states of different periods are deviated, and the pre-pressing amount of the glass lifter needs to be checked and adjusted regularly.
The traditional frameless lifter needs to adjust the height difference between an upper screw and a lower screw and a guide rail when the glass is prepressed in the Y direction to realize the prepressing amount adjustment of the glass, but the adjusting structure adopted by my department and other companies currently has two defects:
1. an adjustment assembly with Y-direction height adjustment and X-direction rotation can only be assembled at the end of the guide rail, as shown in fig. 1, using the glass 101, the bracket and the guide rail 102 as a lever, when the point O1 is used as a fulcrum, and when the rotational position of the point O2 is S1, the displacement amount s2++s1 (l1+l2)/L1 of the glass vertex O3 is larger, and the shorter the L2 is, the more limited the glass adjustment margin is.
2. When a conventional adjusting structure (for example, a structure described in a patent No. cn202120160495.X, entitled as a structure for adjusting a glass lifter in a Y direction) is mounted on a lifter rail, it is necessary to turn a flange on the rail, to provide two parallel turned edges with through holes 103 on the rail, and to insert elastic pins 104 of the adjusting structure together through the through holes 103 on the two parallel turned edges and pivot nuts of the adjusting structure (as shown in fig. 2).
Due to the structural limitation of the existing adjusting structure, the guide rail needs to be subjected to flanging design in the production process, and the development cost of the guide rail die and the price of a guide rail single product are high; meanwhile, based on the adjusting structure, the requirement on the coaxiality of two through holes formed in the two flanging of the guide rail is higher; in addition, as the double-headed screw of the adjusting structure can rotate and also can axially rotate around the elastic pin by a certain angle, the assembling process of the adjusting structure and the guide rail needs to be particularly paid attention to so as to meet the adjustment of the pre-pressing amount of the glass. The adjusting structure in the prior art is complex in assembly process with the guide rail due to structural limitation, and the maintenance cost of the tooling for controlling the pin shaft is high after long-term use. Therefore, it is necessary to provide a new adjusting structure, which can reduce the production cost of the guide rail and the assembly cost of the glass lifter while satisfying the adjustment of the pre-pressing amount of the glass.

Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
As shown in fig. 3, 4 and 6, a steering adjustment structure of a frameless glass lifter comprises a fastening bolt 1, wherein the fastening bolt 1 is a double-ended screw in the prior art, and the structure is the same as that in the prior art (the double-ended screw in the patent with the patent number of CN202120160495. X), and mainly plays a role in rotating adjustment. Because the fastening bolt 1 needs to have a certain amount of swing along the connection point of the fastening bolt 1 and the guide rail 102 when in use, the invention combines the use requirement thereof, and provides a novel adjusting structure which comprises a mounting base 2 and a connecting nut 3, wherein the mounting base 2 is provided with a mounting through hole 25, the connecting nut 3 is embedded in the mounting through hole 25 and is rotationally arranged in the mounting through hole 25, the fastening bolt 1 is deeply connected with the connecting nut 3 in a threaded manner, the connecting nut 3 is provided with a limiting structure for limiting the fastening bolt 1 and the mounting through hole 25 to rotate along the threaded rotation direction of the fastening bolt 1, and the fastening bolt 1 swings under the action of external force to drive the connecting nut 3 to rotate in the mounting through hole 25.
In order to enable the coupling nut 3 to be inserted into the mounting through-hole 25 and to be rotatable in the mounting through-hole 25; and also ensures that the coupling nut 3 cannot rotate in this direction in the mounting through hole 25 again when the coupling nut 3 is rotatably connected to the fastening bolt 1. The present invention provides a structure of the coupling nut 3 capable of achieving the above-mentioned effects. As shown in fig. 2, 3 and 4, the external structure of the coupling nut 3 is substantially hemispherical (as shown in fig. 7 (1)), and of course, the external shape of the coupling nut 3 is not limited to hemispherical, but may be a rotatable semi-cylindrical shape (as shown in fig. 7 (2)), as long as the coupling nut 3 can rotate in a specific direction within the mounting through hole 25, and the coupling nut 3 does not rotate within the mounting through hole 25 when the fastening bolt 1 is rotatably coupled with the coupling nut 3. Based on the structure of the coupling nut 3 in this embodiment, the outer periphery of the coupling nut 3 includes two opposite straight side walls 32 and two opposite outwardly protruding arc side walls 31, and any straight side wall 32 is located between and connected to the two arc side walls 31. The two straight side walls 32 on the connecting nut 3 can limit the rotation direction of the connecting nut 3, so that when the fastening bolt 1 is connected with the connecting nut 3 in a rotation way, the connecting nut 3 rotates in the mounting through hole 25, and the two arc side walls 31 can drive the connecting nut 3 to rotate in the mounting through hole 25 along the arc direction of the arc side walls 31 under the action of external force, thereby achieving the use function of the adjusting structure in the prior art. Of course, the overall shape of the curved side wall 31 may be hemispherical or semi-cylindrical, and the purpose is to ensure that the curved side wall 31 rotates in a predetermined direction when contacting the inside of the portion of the mounting hole 25.
In order to enable the installation through hole 25 to be provided, the connecting nut 3 can be embedded, and the connecting nut 3 can be rotated or braked in the installation through hole 25 according to the use requirement. On the basis of the structure of the connecting nut 3, the invention is provided with a mounting through hole 25 structure matched with the structure of the connecting nut 3, as shown in fig. 4 and 5, the inner wall of the mounting through hole 25 is provided with a planar inner wall 24 which is matched with a limiting structure for use and two curved inner walls 22 which are oppositely arranged and outwards protruded, and any planar inner wall 24 is positioned between the two curved inner walls 22 and is connected. When the connecting nut 3 is embedded in the mounting through hole 25, the two straight side walls 32 of the connecting nut 3 are just fit with the two plane inner walls 24 in the mounting through hole 25, and the two arc side walls 31 of the connecting nut 3 are matched with the two curved inner walls 22 of the mounting through hole 25. The mounting through hole 25 and the connecting nut 3 with the structure can ensure that the positions of the connecting nut 3 and the mounting through hole 25 are basically unchanged in the process of rotating the fastening bolt 1 and connecting the fastening nut 3 by bolts, thereby achieving the effect of braking the connecting nut 3 and further realizing the aim of adjusting the pre-pressing amount by rotating the fastening bolt 1; the curved inner wall 22 of the mounting through hole 25 is matched with the curved side wall 31 of the connecting nut 3, and when the fastening bolt 1 swings along the axial direction, the connecting nut 3 can rotate in the mounting through hole 25, so that the required mounting purpose is achieved.
The design of curved surface inner wall 22 and coupling nut 3 arc lateral wall 31 of installation through-hole 25 not only can effectively provide coupling nut 3 rotation from top to bottom's function, can also effectively increase coupling nut 3 and the area of contact of installation through-hole 25 inner wall, increases the atress transmission effect, promotes stability. The attachment of the two straight side walls 32 of the connecting nut 3 to the two planar inner walls 24 in the mounting through hole 25 can effectively avoid the axial rotation of the connecting nut 3 along the fastening bolt 1, and if the structural design is not provided, the connecting nut 3 will follow the fastening bolt 1 to rotate. The outer structure of the mounting through hole 25 may be arbitrarily set, and only the inner structure of the mounting through hole 25 is required to be matched with the outer peripheral structure of the coupling nut 3.
In summary, the principle of the present invention is as follows, in combination with the structure of the mounting through hole 25 and the coupling nut 3:
when the adjusting structure is used, the mounting base 2 and the guide rail 102 of the lifter are fixed in a welding or riveting mode, and strip-shaped holes (rectangular holes) which are opposite to the mounting through holes 25 are reserved in the guide rail 102, so that the guide rail 102 can be finely adjusted after being connected with the adjusting structure; then the fastening bolt 1 passes through the strip-shaped hole of the guide rail 102 and is in threaded connection with the connecting nut 3 embedded in the mounting through hole 25; due to the existence of the limiting structure, the fastening bolt 1 can smoothly be in rotary connection with the connecting nut 3 and the connection quantity of the fastening bolt 1 and the connecting nut 3 can be adjusted; in addition, the connecting nut 3 can rotate in the mounting through hole 25, and the pre-pressing amount of the glass lifter can be changed by rotating the fastening screw, so that the aim of adjusting the pre-pressing amount of the glass lifter in the prior art is fulfilled by the adjusting structure.
The invention provides a novel adjusting structure, which is based on the improvement of the whole structure of the adjusting structure on the premise of realizing the adjusting function, so that a flanging structure is not required to be additionally arranged on the guide rail 102, and the production and manufacturing cost of the guide rail 102 is reduced.
Meanwhile, due to the improvement of the overall structure of the adjusting structure, the connection between the mounting base 2 and the guide rail 102 is more convenient, the overall mounting of the lifter with the guide rail 102 is quicker, and the mounting cost of the lifter is saved.
Finally, due to the improvement of the integral adjusting structure, the installation position of the adjusting structure on the guide rail 102 is variable, and the adjusting structure is not limited to the position of the upper end part of the guide rail 102 in the prior art, so that the length ratio of L1 to L2 in the figure 1 can be effectively improved by designing the double-headed screws with the same length at different positions, and the Y-direction pre-pressing amount of the guide rail 102 can be improved under the condition of not lengthening the double-headed screws.
Further, in order to facilitate the rotation of the coupling nut 3 in the mounting through hole 25 under the action of the fastening bolt 1, the aperture of the mounting through hole 25 provided in the present invention is necessarily larger than the inner diameter of the coupling nut 3, so that the fastening bolt 1 coupled with the coupling nut 3 can also have a sufficient swing space.
Further, in order to facilitate the production and processing of the installation base 2 and the connection nut 3, the invention detachably connects the connection nut 3 with the installation base 2. As shown in fig. 3, 4 and 5, in particular, since the coupling nut 3 can rotate in the arc direction of the two arc-shaped side walls 31 of the coupling nut 3 within the mounting through hole 25; when the coupling nut 3 is not coupled with the fastening bolt 1, the coupling nut 3 may be rotated to a position where the arc-shaped side wall 31 thereof is located at the opening of the installation through-hole 25 (i.e., a state in which the coupling nut 3 is rotated by 90 ° around the view direction in fig. 3), and then the coupling nut 3 may be taken out of the installation through-hole 25 by an external force; when the coupling nut 3 is required to be coupled to the mounting through hole 25, the coupling nut 3 is installed in the mounting through hole 25 in a state as shown in fig. 3 by only reversing the operation, and then the fastening screw penetrates through the bar-shaped hole of the guide rail 102 and penetrates into the mounting through hole 25 to be screwed with the coupling nut 3. Therefore, based on the structures of the connecting nut 3 and the mounting through hole 25, the connecting nut 3 can be detachably connected with the mounting through hole 25, and the production and processing can be independently carried out in the production and processing process, so that the production and processing difficulty of the mounting base 2 and the connecting nut 3 is reduced. In addition, the assembly process of the connecting nut 3 and the mounting through hole 25 is extremely simple and convenient, and the assembly efficiency of the lifter assembly is improved.
Further, in order to enable the connecting nut 3 to be inserted into the mounting through hole 25 smoothly and to facilitate the insertion process of the connecting nut 3, a guiding plane 24 is provided along the through hole direction of the mounting through hole 25 at the connection position of any curved inner wall 22 and two plane inner walls 24 in the mounting through hole 25. As shown in fig. 4 and 5, four guide planes 24 are provided at each end of the mounting through hole 25, the four guide planes 24 extend into the mounting through hole 25, and the guide planes 24 have a certain inclination angle for guiding when designed, so that the connection nut 3 inserted into the mounting through hole 25 along the guide planes 24 can smoothly enter. Specifically, it is understood that the four guide planes 24 provided at each end of the installation through-hole 25 are inclined in a contracted state from the outside of the installation through-hole 25 to the inside of the installation through-hole 25; or, four guide planes 24 provided at each end of the installation through-hole 25 are inclined in a diffused state from inside the installation through-hole 25 to outside the installation through-hole 25. The guide plane 24 plays a guiding role of the connecting nut 3 in the inserting process and plays a role of avoiding the connecting nut 3, and the rotation of the connecting nut 3 is not affected, so that the connecting nut 3 cannot penetrate into the base without the design structure.
Further, since the mounting base 2 is directly fixedly connected with the guide rail 102, in order to facilitate the fixing of the mounting base 2 and the guide rail 102, the mounting base 2 is provided with the mounting side lugs 21 extending outwards, and the number of the mounting side lugs 21 can be one or a plurality. The mounting position of the mounting side ear 21 can be set according to the requirement, and the main purpose of the mounting side ear is to facilitate the fixed connection between the whole mounting base 2 and the guide rail 102.
To enable the mounting side ears 21 to be attached to the guide rail 102, in this embodiment, the mounting side ears 21 extend outwardly along any open end of the mounting through holes 25 and are disposed flush with the open ends of the mounting through holes 25. As shown in fig. 4 and 5, the mounting side ears 21 are attached to the guide rail 102, and according to the selection of the fixing mode of the mounting side ears 21 and the guide rail 102, riveting holes can be formed on the mounting side ears 21, so that the mounting side ears 21 and the guide rail 102 can be conveniently riveted and fixed; alternatively, the fixing of the mounting base 2, the mounting through hole 25, and the guide rail 102 can be achieved by directly fixing the mounting side ear 21 to the guide rail 102 by welding without providing a caulking hole in the mounting side ear 21.
Of course, in some special cases, the rail 102 is not horizontal; at this time, the mounting side ears 21 may be disposed to extend outward near the open ends of the mounting through holes 25 and may be offset by a certain angle along the open ends of the mounting through holes 25; or the mounting side ears 21 may have a certain distance from the open ends of the mounting through holes 25; only the mounting positions of the mounting side lugs 21 and the mounting through holes 25 are required to be matched with the structure of the guide rail 102, so that the whole mounting base 2 can be fixed with the guide rail 102 after the mounting side lugs 21 and the guide rail 102 are fixed.
Further, to ensure stable connection of the mounting base 2 and the guide rail 102, the number of the mounting ears 21 may be 2, 3, 4, 6, or the like. The stress when the installation side ears 21 are connected with the guide rail 102 can be dispersed by the arrangement of at least two installation side ears 21, the stabilizing effect of the connection of the installation side ears 21 and the guide rail 102 is improved, and the service life of the whole adjusting structure is prolonged. And the setting positions of the plurality of mounting side lugs 21 can be set according to the requirements, so that the whole mounting base 2 is ensured to meet the stress requirements after being connected with the guide rail 102. In this embodiment, as shown in fig. 4 and 5, the number of the mounting lugs 21 is two, and the two mounting lugs 21 are disposed outwardly opposite to each other along the open end of the mounting through hole 25. The mounting lugs 21 may also be disposed at positions rotated 90 ° in the direction of the through hole of the mounting through hole 25 in fig. 5 (i.e., extending outward along the outer sides of the two curved inner walls of the mounting through hole 25).
To further define the interrelationship of the various components of the adjustment structure of the present invention, one will define the following aspects.
1. Referring to fig. 7, 9 and 11, the length of the coupling nut 3 extending out of the mounting through hole 25 when it is fitted into the mounting through hole 25 is defined as b (the extending amount of each end is b); the corresponding spherical radius of the curved inner wall 22 defining the installation through hole 25 is R, and the curved angle of the curved inner wall 22 is α; while defining the length L of the entire coupling nut 3. The formula is satisfied between b, R, α, L: sin (α/2) r= (L/2) -b; wherein b, R and L are variables, and the angle alpha is determined by the first three variables.
2. The design of the guide plane 23 is based on the general hemispherical structure of the coupling nut 3 (the structure in fig. 4), and as shown in fig. 11, based on the hemispherical coupling nut 3, the width L1 of the guide plane 23 extending into the mounting through hole 25 is equal to or greater than 1mm, and in this embodiment, the width of the guide plane 23 extending into the mounting through hole 25 is 1mm. If the overall structure of the coupling nut 3 is substantially semi-cylindrical (as shown in fig. 7 (2)), it is not necessary to provide the guide plane 23 in the mounting through hole 25.
3. In order to smoothly insert or remove the coupling nut 3 into or from the mounting through hole 25 by rotation, as shown in fig. 8, 10, and 12, a distance L2 between two guide planes 23 perpendicular to the longitudinal direction of the mounting through hole 25 is equal to a depth L of a thread in the coupling nut 3 (also referred to as a length of the coupling nut 3) at either end of the mounting through hole 25.
If the coupling nut 3 has a hemispherical structure as shown in fig. 7 (1), the distance C between the two planar inner walls 24 in the mounting hole 25 is as long asIf the coupling nut 3 has a substantially semi-cylindrical structure as shown in fig. 7 (2), the length of the distance C' between the two planar inner walls 24 in the mounting through hole 25 corresponding to this structure satisfies
