Description

Technical Field

[0001] This utility model relates to the field of automotive window regulator technology, and further to a plastic guide rail regulator assembly and vehicle. Background Technology

[0002] Dual-rail window regulators are the core actuators in automotive window and door systems that enable window raising and lowering. In existing technology, such regulators typically consist of two guide rails, two sliders, a motor assembly, and a sheave assembly. The motor assembly provides power to drive the sheave assembly to rotate. The steel cable in the sheave assembly changes direction via a pulley system and pulls the sliders, which in turn move the window glass vertically up and down along the two guide rails.

[0003] However, such lifters have a significant limitation: their guide rail assemblies are generally made of metal. Although metal guide rails perform well in terms of strength and rigidity, this contradicts the current automotive industry's urgent need for lightweight components.

[0004] Therefore, it is necessary to design a plastic guide rail lift assembly and vehicle to solve the above problems. Utility Model Content

[0019] One end of the metal gasket is provided with a vertically bent limiting part, which is inserted into the slot and forms a fitting limiting with the boss.

[0020] In some embodiments, the bottom of the mounting groove is provided with a pulley clearance groove and a plurality of oil storage grooves. The pulley clearance groove is located radially outside the pin hole and is positioned below the outer edge of the pulley. The plurality of oil storage grooves are arranged at circumferential intervals along the pin hole.

[0022] The end of the hose extends into the large-diameter section, and its end face abuts axially against the annular limiting step.

[0023] After passing through the hose, the steel wire rope passes through the large-diameter section and the small-diameter section in sequence and extends to connect with the pulley.

[0024] In some embodiments, the top of the assembly slot is provided with a slot opening, and the thickness of the slot opening is not less than 2mm;

Detailed Implementation

[0048] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0049] To keep the drawings concise, each figure only schematically shows the parts relevant to the utility model, and these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0050] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0051] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] In one embodiment, refer to the appendix to the specification. Figures 1 to 3 The present invention provides a plastic guide rail lifting assembly, comprising: two parallel and spaced plastic guide rails 1; two sliders 2, each slidably connected to a corresponding plastic guide rail 1; a sheave assembly 3, disposed on the two plastic guide rails 1 and connected to the two sliders 2 respectively by steel wire ropes 32, with metal pads 4 respectively provided at the connection between the sheave assembly 3 and each plastic guide rail 1; and a motor assembly 5, driven and connected to the sheave assembly 3, for driving the sheave assembly 3 to rotate, thereby driving the two sliders 2 to reciprocate along their respective plastic guide rails 1.

[0054] In this embodiment, dual parallel plastic guide rails are used to replace metal parts to achieve significant weight reduction. At the same time, metal gaskets 4 are set at the connection between the roller assembly 3 and the plastic guide rail 1 to ensure the structural strength of key stress points. This not only greatly reduces the system weight and energy consumption, but also maintains reliable load-bearing performance. Meanwhile, the easy molding characteristics of plastics enable the integrated manufacturing of parts, effectively reducing production costs and assembly complexity.

[0055] In one embodiment, refer to the appendix to the specification. Figure 3 , Figure 4The reel assembly 3 includes: at least four pulleys 31, which are respectively disposed at the ends of two plastic guide rails 1; a steel wire rope 32, which is wound around the pulleys 31 and is respectively connected to two sliders 2; and a flexible hose 33, which is sleeved on the steel wire rope 32, with the ends of the flexible hose 33 respectively connected to the corresponding plastic guide rails 1.

[0056] The plastic guide rail 1 has a mounting groove 11 at its end, and the pulley 31 is rotatably mounted in the mounting groove 11 via a riveting pin 34. A metal washer 4 is located on the side of the plastic guide rail 1 facing away from the mounting groove 11. A pin hole 111 is located at the bottom of the mounting groove 11, and the riveting pin 34 passes through the pulley 31, the pin hole 111, and the metal washer 4 in sequence to securely connect the three. By providing a mounting groove 11 at the end of the plastic guide rail 1, and combining it with the riveting pin 34 and the metal washer 4, a stable and reliable installation of the pulley 31 on the plastic guide rail 1 is achieved. The metal washer 4 is placed on the back of the plastic guide rail 1 and works together with the riveting pin 34 to effectively distribute the dynamic load of the pulley 31 during operation, preventing deformation or cracking caused by local stress concentration in the plastic guide rail 1. This maintains the lightweight advantage of the plastic guide rail 1 while ensuring the structural strength and durability of the lifting device during long-term use.

[0057] Furthermore, the plastic guide rail 1 has a boss 12 on the side facing away from the metal gasket 4 and a slot 121 on the side facing the metal gasket 4. The slot 121 penetrates the thickness direction of the plastic guide rail 1 and extends into the boss 12. One end of the metal gasket 4 has a vertically bent limiting part 41, which is inserted into the slot 121 and forms a fitting limit with the boss 12. By providing the boss 12 and the through slot 121 on the plastic guide rail 1, and cooperating with the bent limiting part 41 of the metal gasket 4, a mechanical interlocking connection is formed. This structure can effectively prevent the metal gasket 4 from shifting or rotating during operation, significantly improving the structural stability of the pulley mounting point. Of course, the metal gasket 4 can also be fixed in other ways, such as inlay fixing or bolt fixing.

[0058] In one embodiment, refer to the appendix to the specification. Figure 4 The bottom of the mounting groove 11 is provided with a pulley clearance groove 112 and several oil storage grooves 113. The pulley clearance groove 112 is located radially outside the pin hole 111 and is positioned below the outer edge of the pulley 31. The several oil storage grooves 113 are arranged circumferentially around the pin hole 111. The clearance groove 112 provides sufficient dynamic clearance for the operation of the pulley 31, effectively preventing rotational interference; the circumferentially distributed oil storage grooves 113 can stably store lubricating grease, ensuring long-term lubrication of the pin, significantly reducing frictional resistance and wear, thereby improving the smoothness, quietness and service life of the lifting system.

[0059] Further, refer to the attached instruction manual. Figures 4 to 6The plastic guide rail 1 has a stepped mounting slot 13, which includes a large-diameter section 131 and a small-diameter section 132 that are coaxially connected. The connection between the large-diameter section 131 and the small-diameter section 132 forms a radially inwardly protruding annular limiting step 133. The end of the hose 33 extends into the large-diameter section 131, and its end face abuts axially with the annular limiting step 133. After the steel wire rope 32 passes through the hose 33, it passes through the large-diameter section 131 and the small-diameter section 132 in sequence and extends to connect with the pulley 31. By setting stepped mounting slots 13 on the plastic guide rail 1, the hose 33 is reliably fixed and the wire rope 32 is accurately guided. The large-diameter section 131 and the annular limiting step 133 cooperate to form an axial stop structure, which effectively prevents the hose 33 from coming off when under force. The small-diameter section 132 forms a radial constraint on the wire rope 32, ensuring accurate running trajectory. While maintaining the advantage of lightweight design, it significantly improves the reliability and durability of the lifting system.

[0060] Furthermore, the top of the assembly slot 13 is provided with a slot opening 134, the thickness of which is not less than 2mm; the length of the small diameter section 132 is not less than 4.5mm; a number of compensating ribs 135 are arranged circumferentially in the large diameter section 131, and the compensating ribs 135 extend along the length direction of the large diameter section 131; radial compensating ribs 136 are provided on both sides of the hole wall of the assembly slot 13, and an axial support rib 137 is provided at the end of the small diameter section 132 away from the large diameter section 131.

[0061] In this embodiment, the strength of the basic structure is ensured by limiting the thickness of the slot opening 134 and the length of the small-diameter section 132. The compensating rib 135 effectively resists the radial stress during hose assembly, the radial compensating rib 136 enhances the tensile strength of the hole wall, and the axial support rib 137 provides end protection under stall load. This structure enables the plastic guide rail 1 to maintain its lightweight characteristics while achieving mechanical properties at the level of metal parts in key stress-bearing components. It solves the problem of easy deformation and cracking of the plastic guide rail 1 under extreme working conditions, and significantly improves the reliability and service life of the lifting assembly.

[0062] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 7 The plastic guide rail 1 has a disassembly hole 14 and a weight reduction hole 15. Vertically extending annular reinforcing ribs 151 are provided on the circumferential edges of both the disassembly hole 14 and the weight reduction hole 15. By providing vertical annular reinforcing ribs 151 around the disassembly hole 14 and the weight reduction hole 15 of the plastic guide rail 1, a perfect balance between lightweight and structural strength is achieved: the weight reduction hole 15 effectively reduces the weight of the component, while the annular reinforcing ribs 151 significantly improve the bending stiffness and crack resistance of the opening area with minimal material increment.

[0063] Furthermore, the side of the plastic guide rail 1 is integrally formed with a working edge 16, which includes a horizontal connecting section 161, a vertical connecting section 162, and an outward bending section 163 connected in sequence; the vertical connecting section 162 extends downward of the horizontal connecting section 161 by a predetermined length, the predetermined length being not less than 3mm; the outward bending section 163 extends away from the horizontal connecting section 161, and the thickness of the outward bending section 163 is not less than 2.5mm; the connection between the horizontal connecting section 161 and the vertical connecting section 162 is rounded, and the rounded corner radius is not less than 2mm; the connection between the vertical connecting section 162 and the outward bending section 163 is rounded, and the rounded corner radius is not less than 2mm.

[0064] In this embodiment, the horizontal connecting section 161 provides a stable support surface, the vertical connecting section 162 ensures structural rigidity, and the outward bending section 163 enhances guiding reliability; the design of a thickness ≥2.5mm and a corner radius ≥2mm in key parts significantly improves impact resistance; this structure allows the plastic guide rail 1 to maintain its lightweight advantage while maintaining the bending strength of the working edge, so that the smoothness of glass operation reaches the level of metal guide rails.

[0065] According to another aspect of the present invention, the present invention further provides a vehicle including the plastic guide rail lift assembly described in any one of the above.

[0066] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0067] It should be noted that the above embodiments can be freely combined as needed. The above are only optional embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
