Description

Technical Field

[0001] This application relates to the field of automotive window regulator technology, and in particular to a window regulator and its spring support structure. Background Technology

[0002] As the device for raising and lowering car windows, power window regulators are mainly divided into two categories: electric and manual. Currently, most cars use push-button electric regulators, where the driver controls all windows via a master switch, while passengers operate individual windows independently via switches on the door handles, significantly improving ease of use. In terms of structural design, to balance cost and simplicity, most power window regulators use springs to achieve the raising and lowering function.

[0003] However, existing technology has significant drawbacks. The spring ends are prone to jamming, and uneven stress leads to misalignment and deformation, directly affecting the lifespan of the window regulator. Specifically, during spring operation, after the spring coils contract and flatten, line contact between the coils can easily generate misaligned noise, which in turn causes the adjusting rod to impact the seat plate, resulting in continuous abnormal noise.

[0004] Therefore, it is necessary to provide a window regulator and its spring support structure. By optimizing the support and guiding design of the spring support, the misalignment phenomenon after spring compression can be effectively suppressed, and the impact between the adjusting rod and the seat plate can be avoided, thereby significantly improving the product's operational stability and long-term reliability. Summary of the Invention

[0005] In view of the shortcomings or deficiencies mentioned in the background technology, the present application provides a window regulator and its spring support structure to solve the problems in the prior art where spring compression on the window regulator easily causes misalignment and abnormal noise, and causes the adjusting rod to collide with the seat plate and generate abnormal noise.

[0006] In a first aspect, embodiments of this application provide a spring support structure for a window regulator, comprising: A seat plate, wherein an interface is provided at the end of the seat plate; An adjusting rod, comprising a top section, a middle section, and a tail section coaxially connected and having progressively smaller cross-sections, wherein the end of the tail section away from the middle section extends into the interface and slides into the interface; A helical spring is sleeved on the middle section and its two ends abut against the top section and the seat plate, respectively. The spring wire of the helical spring is provided with a support surface to prevent radial misalignment of the helical spring. The compression height of the helical spring is greater than the length of the middle section.

[0007] In some embodiments, the cross-section of the spring wire is rectangular, and the helical spring is a rectangular spring made of spring wire with a rectangular cross-section.

[0008] In some embodiments, the support surface includes an upper support surface and a lower support surface disposed at both ends of the spring wire along the axial direction of the helical spring, and the coils of the helical spring form surface contact through the upper support surface and the lower support surface to prevent radial misalignment.

[0009] In some embodiments, the upper support surface and the lower support surface are both flat surfaces perpendicular to the axis of the helical spring.

[0010] In some embodiments, the upper support surface of the spring wire is provided with a recess, and the lower support surface of the spring wire is provided with a protrusion that matches the recess.

[0011] In some embodiments, the cross-section of the spring wire is a circle with a notch, the orientation of the notch is consistent with the axial direction of the helical spring, and the support surface is a concave arc surface forming the notch.

[0012] In one aspect, in some embodiments, the difference between the compression height of the helical spring and the length of the middle section is less than the dimension of the spring wire in the axial direction of the helical spring.

[0013] In some embodiments, the two ends of the helical spring are provided with supporting planes for forming stable surface contact with the top section and the seat plate, respectively.

[0014] In some embodiments, the interface is provided with an axially extending and smooth guide plane, the tail section has a non-circular cross-sectional shape, and the tail section is provided with an axially extending sliding plane that is slidably connected to the guide plane.

[0015] In some embodiments, the end of the seat plate is provided with an annular retaining edge located on the outer ring of the helical spring and surrounding the helical spring, and the inner side of the annular retaining edge is provided with a chamfer.

[0016] In some embodiments, the adjusting rod is provided with an axially penetrating through hole, the through hole including a large-diameter hole section and a small-diameter hole section arranged coaxially, the large-diameter hole section extending from the top section to the middle section, and the small-diameter hole section extending from the middle section to the tail section.

[0017] Secondly, embodiments of this application provide a window regulator, comprising: The spring support structure of the window regulator described in any of the above.

[0018] The beneficial effects of the technical solution provided in this application include: This application provides a window regulator and its spring support structure. The seat plate has an interface at its end. The adjusting rod includes a top section, a middle section, and a tail section that are coaxially connected and have progressively smaller cross-sections. The end of the tail section away from the middle section extends into the interface and slides to match the interface. A helical spring is sleeved on the middle section and its two ends abut against the top section and the seat plate, respectively. The spring wire of the helical spring is provided with a support surface to prevent radial misalignment of the helical spring. The compression height of the helical spring is greater than the length of the middle section.

[0019] Therefore, when the adjusting rod moves toward the base plate, causing the helical spring to compress, the supporting surface of the helical spring makes surface contact between the coils, replacing the line contact design. This effectively suppresses the misalignment phenomenon after the spring is compressed and prevents the friction of misaligned coils from generating abnormal noise. At the same time, the compression height of the helical spring is greater than the length of the middle section, ensuring that the middle section will not contact the base plate when the spring is compressed to its minimum height. This avoids the impact between the adjusting rod and the base plate, thereby significantly improving the product's operational stability and long-term reliability. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] In view of the shortcomings or deficiencies mentioned in the background technology, the present application provides a window regulator and its spring support structure to solve the problems in the prior art where spring compression on the window regulator easily causes misalignment and abnormal noise, and causes the adjusting rod to collide with the seat plate and generate abnormal noise.

[0025] See Figures 1 to 8 As shown, the first aspect of this application provides a spring support structure for a window regulator, comprising: Seat plate 1, with an interface 11 provided at one end; Adjusting rod 2 includes a top section 21, a middle section 22 and a tail section 23 that are coaxially connected and whose cross-sections decrease sequentially. The end of the tail section 23 away from the middle section 22 extends into the interface 11 and slides to match the interface 11. The helical spring 3 is sleeved on the middle section 22 and its two ends abut against the top section 21 and the seat plate 1 respectively. The spring wire 31 of the helical spring 3 is provided with a support surface 32 to prevent the helical spring 3 from radially misaligning. The compression height of the helical spring 3 is greater than the length of the middle section 22.

[0026] The spring bracket structure of this application embodiment provides a dedicated support surface 32 on the spring wire 31 of the helical spring 3. When the adjusting rod 2 moves toward the seat plate 1, causing the helical spring 3 to be pressed together, the support surface 32 makes the spring coils form a surface contact, effectively replacing the line contact design after the traditional round cross section spring 7 is pressed together, greatly suppressing the misalignment phenomenon after the spring is pressed together and eliminating the abnormal noise caused by misalignment friction. Meanwhile, the compression height of the helical spring 3 is precisely designed to be greater than the length of the middle section 22 of the adjusting rod 2, ensuring that the middle section 22 and the seat plate 1 always maintain a safe gap when the spring is compressed to its minimum height, thus completely avoiding the impact between the adjusting rod 2 and the seat plate 1.

[0027] This design optimizes the uniformity of force distribution on the spring during compression, reduces frictional losses, significantly improves the smoothness and quietness of the window regulator's operation, extends product lifespan, and makes the raising and lowering of vehicle doors and windows quieter and more reliable, providing users with a better driving experience. Moreover, it can be applied on a large scale without additional costs.

[0028] Firstly, in some alternative embodiments: see Figure 2 As shown, this application embodiment provides a spring support structure for a glass lifter. The spring wire 31 of the spring support structure of the glass lifter has a rectangular cross-section, and the helical spring 3 is a rectangular spring wound with the spring wire 31 with a rectangular cross-section.

[0029] In this embodiment, the helical spring 3 is a rectangular spring wound with spring wire 31 with a rectangular cross section. After compression, the support surface 32 can be regarded as a plane, so that the spring coils can achieve surface contact instead of the line contact of the traditional circular cross section spring 7, effectively suppressing the mis-coil phenomenon and eliminating friction noise.

[0030] When the rectangular spring is compressed to its minimum height, this height is precisely equal to the compression height, and the compression height is designed to be greater than the length of the middle section 22 of the adjusting rod 2, ensuring that the middle section 22 and the seat plate 1 always maintain a safe clearance and avoid any collision. This structural optimization significantly improves the smoothness of the window regulator's operation, the quietness, and the long-term reliability, achieving quiet and reliable window and door lifting operations without additional costs.

[0031] Firstly, in some alternative embodiments: see Figures 2 to 4 As shown, this application embodiment provides a spring support structure for a glass lifter. The support surface 32 of the spring support structure of the glass lifter includes an upper support surface 321 and a lower support surface 322 disposed at both ends of the spring wire 31 along the axial direction of the helical spring 3. The coils of the helical spring 3 form surface contact through the upper support surface 321 and the lower support surface 322 to prevent radial misalignment.

[0032] In this embodiment, the support surface 32 includes an upper support surface 321 and a lower support surface 322 disposed at both ends of the spring wire 31 along the axial direction of the helical spring 3. The radial misalignment of the spring during the compression process is effectively suppressed by the surface contact between the coils of the helical spring 3.

[0033] In specific implementation, the upper support surface 321 and the lower support surface 322 of the circular cross-section spring 7 can be formed by grinding the two ends of the spring wire 31, while the rectangular spring directly uses the upper and lower end surfaces of its spring wire 31 as the support surface 32.

[0034] This design ensures stable surface contact between the coils when the springs are compressed, eliminating friction noise from misaligned coils. Simultaneously, the compression height exceeds the length of the middle section 22 of the adjusting rod 2, preventing collisions between the adjusting rod 2 and the seat plate 1, significantly improving the smoothness and long-term reliability of the window regulator. In other embodiments, a helical spring 3 made of spring wire 31 with a hexagonal or octagonal cross-section can also be used.

[0035] Firstly, in some alternative embodiments: see Figures 2 to 4 As shown, this application embodiment provides a spring support structure for a glass lifter. The upper support surface 321 and the lower support surface 322 of the spring support structure are both flat surfaces perpendicular to the axis of the helical spring 3.

[0036] In this embodiment, both the upper support surface 321 and the lower support surface 322 are perpendicular to the axis of the helical spring 3, forming flat surfaces. This ensures that when the spring is compressed, the coils achieve surface contact instead of traditional line contact, effectively suppressing radial misalignment and frictional noise. This design is simple and reliable, requiring no additional processing, and significantly improves the stability of the spring compression process, thereby ensuring smooth and quiet operation of the window regulator and extending the product's service life.

[0037] Firstly, in some alternative embodiments: see Figures 2 to 6 As shown, this application embodiment provides a spring support structure for a glass lifter. The upper support surface 321 of the spring wire 31 of the glass lifter spring support structure is provided with a recess 3211, and the lower support surface 322 of the spring wire 31 is provided with a protrusion 3221 that matches the recess 3211.

[0038] In this embodiment, the upper support surface 321 of the spring wire 31 is provided with a recess 3211, and the lower support surface 322 is provided with a protrusion 3221 that matches the recess 3211. When the helical spring 3 is compressed, the corresponding protrusions 3221 between each coil are pressed into the recess 3211, thereby locking the coils together and effectively suppressing radial misalignment and friction noise.

[0039] The recess 3211 can be designed as a V-shaped groove, and the corresponding protrusion 3221 can be designed as a V-shaped protrusion; or the recess 3211 can be designed as a concave arc groove, and the corresponding protrusion 3221 can be designed as a convex arc block; ensuring that each ring fits tightly during the pressing process. This structure requires no additional parts, simplifies the manufacturing process, improves the spring compression stability, eliminates abnormal operating noise, and maintains controllable minimum spring height, significantly improving the quiet performance and long-term reliability of the window regulator.

[0040] Firstly, in some alternative embodiments: see Figure 7 and Figure 8As shown, this application embodiment provides a spring support structure for a glass lifter. The cross-section of the spring wire 31 of the spring support structure of the glass lifter is a circle with a notch 4. The orientation of the notch 4 is consistent with the axial direction of the helical spring 3. The support surface 32 is a concave arc surface forming the notch 4.

[0041] In this embodiment, the cross-section of the spring wire 31 adopts a circular design with a notch 4. The orientation of the notch 4 is consistent with the axial direction of the helical spring 3. The support surface 32 is a concave arc surface formed by the notch 4, and the side facing away from the notch 4 is a convex arc surface formed by the spring wire 31 itself.

[0042] When the helical springs are compressed, the corresponding convex arc surfaces of each coil are pressed into the concave arc surfaces to achieve mutual locking, effectively suppressing radial misalignment and friction noise, avoiding misalignment and deformation after the springs are compressed, ensuring stable and reliable compression process, and significantly improving the quietness of the window regulator operation and its long service life.

[0043] Firstly, in some alternative embodiments: see Figure 2 As shown, this application embodiment provides a spring support structure for a glass lifter, wherein the difference between the height of the coil spring 3 and the length of the middle section 22 in the spring support structure of the glass lifter is less than the axial dimension of the spring wire 31 in the coil spring 3.

[0044] In this embodiment, the difference between the compression height of the helical spring 3 and the length of the middle section 22 is strictly controlled within a range less than the axial thickness of the spring wire 31. This ensures that when the spring is compressed to its limit, the last coil can still be effectively radially constrained by the middle section 22, completely eliminating the risk of mis-coil. A small gap can be provided between the middle section 22 and the helical spring 3 to avoid contact friction, or the contact surface can be smoothed to further suppress abnormal noise.

[0045] This design ensures a stable and reliable spring compression process by precisely matching key dimensional parameters, significantly improving the smoothness and quietness of the window regulator's operation, extending the product's lifespan, and achieving a synergistic optimization of high performance and low cost without the need for additional components or complex processes. This provides a quiet and durable user experience for vehicle window and door operation.

[0046] Firstly, in some alternative embodiments: see Figures 2 to 8 As shown, this application embodiment provides a spring support structure for a glass lifter. The two ends of the helical spring 3 of the glass lifter spring support structure are provided with support planes 5 for forming stable contact with the top section 21 and the seat plate 1 respectively.

[0047] In this embodiment, the helical spring 3 has supporting planes 5 at both ends, and the supporting planes 5 at both ends form stable surface contact with the top section 21 and the seat plate 1, respectively. During the spring compression process, the surface contact effectively suppresses offset, avoids slippage of the ends of the helical spring 3, improves the smoothness and long-term reliability of the window regulator, and ensures a quiet, stable, and durable user experience.

[0048] Firstly, in some alternative embodiments: see Figures 2 to 8 As shown, this application embodiment provides a spring support structure for a glass lifter. The interface 11 of the spring support structure of the glass lifter is provided with an axially extending and smooth guide plane. The cross-sectional shape of the tail section 23 is non-circular, and the tail section 23 is provided with an axially extending sliding plane that is slidably connected to the guide plane.

[0049] In this embodiment, the interface 11 is provided with an axially extending and smooth guide plane, and the tail section 23 is designed to be non-circular in cross-section, such as rectangular, regular pentagonal or regular hexagonal, etc. The tail section 23 has an axial sliding plane that matches and slides with the guide plane.

[0050] This design effectively prevents the adjusting rod 2 from rotating during the lifting process, ensuring a stable and precise movement trajectory, eliminating jamming or abnormal noise caused by rotation, significantly improving the smoothness, quietness and long-term reliability of the window regulator, while simplifying the assembly process and extending the product's service life.

[0051] Firstly, in some alternative embodiments: see Figures 2 to 8 As shown, this application embodiment provides a spring support structure for a glass lifter. The end of the seat plate 1 of the spring support structure of the glass lifter is provided with an annular stop 12 located on the outer ring of the helical spring 3 and surrounding the helical spring 3. The inner side of the annular stop 12 is provided with a chamfer.

[0052] In this embodiment, the end of the base plate 1 has an integrally formed annular retaining edge 12 that surrounds the outer ring of the helical spring 3, with a chamfer on the inner side. This design provides radial limiting and protection during spring compression; the chamfered structure facilitates the quick insertion and installation of the helical spring 3, reducing assembly difficulty.

[0053] Firstly, in some alternative embodiments: see Figures 2 to 8 As shown, this application embodiment provides a spring support structure for a glass lifter. The adjusting rod 2 of the spring support structure of the glass lifter is provided with an axially penetrating through hole 6. The through hole 6 includes a large-diameter hole section 61 and a small-diameter hole section 62 arranged coaxially. The large-diameter hole section 61 extends from the top section 21 to the middle section 22, and the small-diameter hole section 62 extends from the middle section 22 to the tail section 23.

[0054] In this embodiment, the adjusting rod 2 is provided with an axially penetrating through hole 6, which is composed of a coaxial large-diameter hole section 61 and a small-diameter hole section 62. The large-diameter hole section 61 facilitates the insertion and fixing of the wire rope sleeve, achieving a stable installation of the wire rope; the small-diameter hole section 62 facilitates the wire rope to pass through and connect to the motor-driven winding wheel on the base plate 1, ensuring a smooth and reliable connection process and significantly improving the assembly efficiency and operational stability of the window regulator.

The surface contact design of the spring support surface effectively suppresses misalignment and abnormal noise, while ensuring that the compression height is greater than the middle length of the adjusting rod to avoid impact. This significantly improves the smoothness of operation, the quietness effect and the long-term reliability, and achieves a quiet and smooth window lifting process. It optimizes product performance without additional costs and brings users a better driving experience.
