Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a rope wheel type electric window regulator motor for automobiles. Background Technology

[0002] In the modern automotive industry, power windows have become a standard feature for enhancing driving comfort and convenience. Rope pulley-type power window regulators, as one of the mainstream technologies, use a motor-driven reel to wind and unwind a steel cable, thereby causing the glass to slide up and down along a guide rail. This type of regulator is widely used in various vehicle models due to its relatively simple structure, controllable cost, and small footprint. Therefore, optimizing the reliability, smoothness, and durability of its core drive motor and transmission system is of great significance for improving overall vehicle quality and user experience.

[0003] In existing technology, the conventional rope-driven electric window regulator motor assembly mainly consists of a DC motor body, a gear reduction mechanism, and a winding reel (also called a rope drum) connected to the reduction mechanism. Its working principle is as follows: after the motor is powered on, the gear set reduces speed and increases torque, driving the winding reel to rotate. A flexible steel cable (rope) is wound around the winding reel, with both ends connected to a slider or bracket fixed to the lower edge of the window glass. The middle part of the cable is arranged within a closed path formed by several fixed guide wheels and guide tubes. When the motor rotates forward or reverse, the winding reel correspondingly winds up one end of the cable and releases the other end. Through this "pull-release" action, the glass bracket is pulled up and down along the guide rail inside the door, realizing the raising and lowering of the window.

[0004] However, the aforementioned existing technologies have a significant design flaw in terms of rope guidance and tension control: their rope guidance system structure is too fixed and cannot adapt to potential diameter tolerance variations in the rope itself, easily leading to rope jamming during operation. Specifically, the groove dimensions of traditional guide wheels and guide tubes are precisely machined according to the standard rope diameter with a fixed gap, lacking any adjustment or elasticity. In actual production and long-term use, the rope may have slight unevenness in thickness due to batch differences in manufacturing, or local diameter changes due to wear and stretching. When the rope diameter is slightly larger than the standard value, it will be tightly squeezed into the fixed guide groove, resulting in a sharp increase in running resistance, accelerated wear, and in severe cases, direct jamming, causing lifting failure; conversely, if the rope is too thin, play will be generated in the groove, causing vibration, noise, and even the risk of detachment from the guide rail. Therefore, a rope wheel type automotive electric window regulator motor is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rope-wheel type electric window regulator motor for automobiles, aiming to improve the existing rope guidance system structure, which is fixed and unable to adapt to changes in rope diameter tolerance. This easily leads to jamming when the rope is too thick, and vibration and noise when it is too thin, seriously affecting the smoothness and reliability of the regulator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rope-wheel type automotive electric window regulator motor, comprising a mounting housing, a connecting housing on the upper side of the mounting housing, a motor body fixedly connected to one side of the connecting housing, an interface on one side of the motor body, multiple mounting seats fixedly connected inside the connecting housing, mounting bolts penetrating inside the mounting housing, a positioning seat fixedly connected inside the mounting housing, a winding wheel at the output end of the motor body, the inner wall of the winding wheel rotatably connected to the outer wall of the positioning seat, a through groove inside the mounting housing, and an anti-jamming component installed inside the mounting housing;

[0007] The anti-jamming assembly includes a sealing tube, the outer wall of which is fixedly connected to the inside of a through groove inside the mounting shell. A spring is sleeved on the outer wall of the sealing tube. Multiple mounting boxes are fixedly connected to the inner wall of the through groove. A spring is slidably connected inside the mounting box. A limit plate is fixedly connected to one end of the spring. A limit wheel is rotatably connected inside the limit plate.

[0008] As a further description of the above technical solution:

[0009] Multiple insertion rods are fixedly connected inside the mounting housing, and limit strips are fixedly connected to the outer wall of the insertion rods.

[0010] As a further description of the above technical solution:

[0011] The mounting base has a limiting groove inside for the limiting strip to slide, and the outer wall of the insertion rod is slidably connected to the inside of the mounting base.

[0012] As a further description of the above technical solution:

[0013] The insert rod is internally threaded with an adjusting bolt, and a tapered block is fixedly connected to the upper end of the adjusting bolt.

[0014] As a further description of the above technical solution:

[0015] The insert rod is slidably connected to a locking block, and an arc-shaped plate is fixedly connected to one side of the outer wall of the locking block.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the card block is disposed inside the insertion rod, and the outer wall of the card block is engaged in the slot of the inner wall of the mounting base.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the conical block is slidably connected to the inner wall of the insertion rod, and the outer wall of the conical block abuts against one side of the inner wall of the arc-shaped plate.

[0020] As a further description of the above technical solution:

[0021] One end of the spring is fixedly connected to one side of the outer wall of the sealing tube, and the other end of the spring is fixedly connected to one side of the outer wall of the mounting shell.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the mounting shell and the connecting shell are installed and connected, the motor body drives the winding wheel to rotate the rope, thereby achieving the effect of driving the rope to slide inside the sealed tube. When the rope slides inside the sealed tube, the extension and retraction will slide between multiple limit wheels. At this time, the limit wheels drive the limit plate to slide inside the mounting box, thereby achieving the effect of compressing the second spring to extend and retract. At this time, through the extension and retraction of the second spring, it is possible to adapt to the movement of ropes of different thicknesses while cooperating with the movement of the limit wheels, thereby preventing jamming during the extension and retraction process, thus improving the practicality of the motor.

[0024] 2. In this utility model, the adjusting bolt is rotated inside the insertion rod. The rotation of the adjusting bolt facilitates the removal of the adjusting bolt from the outer wall of the arc plate. Then, the arc plate causes the locking block to disengage from the slot inside the mounting base. After the locking block disengages from the mounting base, the mounting shell can be quickly disassembled, making it easier for workers to disassemble and repair the internal parts of the connecting shell, thereby improving the practicality of the motor.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-5 This utility model provides an embodiment of a rope-wheel type automotive electric window regulator motor, including a mounting shell 1, which serves as the main frame, housing internal components and providing an external mounting base. A connecting shell 2 is provided on the upper side of the mounting shell 1, forming a closed cavity with the mounting shell 1 to protect the internal transmission system. A motor body 3 is fixedly connected to one side of the connecting shell 2, providing the driving force source for the entire regulator. An interface 4 is provided on one side of the motor body 3 for connecting external power and control signals. Multiple mounting seats 5 are fixedly connected inside the connecting shell 2 for internal... For precise positioning and fixing of the components, mounting bolts 6 are installed through the inside of the mounting housing 1. These mounting bolts 6 are used to fix the entire device to the door structure. A positioning seat 7 is fixedly connected inside the mounting housing 1. The positioning seat 7 provides a rotation center and radial support for the winding wheel 8. The output end of the motor body 3 is provided with a winding wheel 8. The winding wheel 8 is used to directly perform the winding and unwinding action of the rope. The inner wall of the winding wheel 8 is rotatably connected to the outer wall of the positioning seat 7 to achieve smooth rotational transmission. A through groove 9 is opened inside the mounting housing 1. This through groove 9 provides space and reference for the installation of the anti-jamming component. The anti-jamming component is installed inside the mounting housing 1.

[0034] The anti-jamming assembly includes a sealing tube 10, which provides initial constraint and protection for the rope's running path. The outer wall of the sealing tube 10 is fixedly connected to the through groove 9 inside the mounting shell 1. A spring 11 is sleeved on the outer wall of the sealing tube 10, which applies an axial preload to the sealing tube 10 to eliminate vibrations caused by its installation gap. Multiple mounting boxes 12 are fixedly connected to the inner wall of the through groove 9, serving as carriers for accommodating the elastic limiting mechanism. A limiting plate 14 is slidably connected inside the mounting box 12 (according to the structural function, this should be the limiting plate 14 in...). The cable slides inside the mounting box 12 and is subject to the elastic action of spring 13. Spring 13 is the core elastic element for achieving adaptive adjustment. One end of spring 13 is fixedly connected to a limiting plate 14, which acts as a force transmitter to sense the radial change of the cable. A limiting wheel 15 is rotatably connected inside the limiting plate 14. The limiting wheel 15 is in direct contact with the cable and guides the cable by rolling. One end of spring 11 is fixedly connected to one side of the outer wall of the sealing tube 10, and the other end of spring 11 is fixedly connected to one side of the outer wall of the mounting shell 1.

[0035] Specifically, the main body of the device is formed by the mounting shell 1 and the connecting shell 2, providing a stable mounting and housing space for the motor body 3, winding reel 8, and other working components. The positioning seat 7 ensures the rotational accuracy of the winding reel 8. Crucially, an anti-jamming component is installed inside the through groove 9 of the mounting shell 1. This component is guided by the sealing tube 10 and forms a crucial control over the rope path through an elastic limiting mechanism composed of the mounting box 12, spring 13, limiting plate 14, and limiting wheel 15.

[0036] Reference Figures 1-5Multiple insert rods 16 are fixedly connected inside the mounting shell 1. These insert rods 16 serve as the basis for locking the shell. Limiting strips 17 are fixedly connected to the outer walls of the insert rods 16. These limiting strips 17 cooperate with limiting grooves in the mounting base 5 to prevent circumferential rotation of the insert rods 16 during assembly, ensuring their correct orientation. The mounting base 5 has a limiting groove inside for the sliding of the limiting strips 17. The outer walls of the insert rods 16 are slidably connected inside the mounting base 5. This constitutes the insertion guide relationship between the mounting shell 1 and the connecting shell 2. An adjusting bolt 18 is threaded inside the insert rod 16. This adjusting bolt 18 is the active component for locking or unlocking operations. A conical block 19 is fixedly connected to the upper end of the adjusting bolt 18. Block 19, through its tapered inclined surface, converts the axial movement of the adjusting bolt 18 into a radial driving force on the locking block 21. The locking block 21 is slidably connected inside the insert rod 16, serving as the final actuator for locking. An arc-shaped plate 20 is fixedly connected to one side of the outer wall of the locking block 21; this arc-shaped plate 20 acts as a force-bearing surface, abutting against the outer wall of the tapered block 19. The outer wall of the locking block 21 penetrates the interior of the insert rod 16, engaging in a groove on the inner wall of the mounting base 5. This radially locks the insert rod 16 to the mounting base 5, achieving a fixed connection between the mounting shell 1 and the connecting shell 2. The outer wall of the tapered block 19 is slidably connected to the inner wall of the insert rod 16, and abuts against one side of the inner wall of the arc-shaped plate 20. Through this contact relationship, the locking force is transmitted to the locking block 21.

[0037] Specifically, by setting a plug 16 on the mounting shell 1 and a corresponding mating hole on the mounting base 5 of the connecting shell 2, the basic assembly relationship between the two shells is established. The core of this mechanism lies in a wedge-shaped locking mechanism driven by an adjusting bolt 18. During locking, rotating the adjusting bolt 18 causes it to move axially, which in turn drives the conical block 19 to use its inclined surface to radially push the locking block 21 out and into the slot of the mounting base 5, thus firmly locking the two shells together. When disassembly is required, rotating the adjusting bolt 18 in the opposite direction causes the conical block 19 to retract, releasing the pushing force on the locking block 21. The locking block 21 then disengages from the slot, allowing the two shells to separate.

[0038] Working principle: When the motor is needed, the output end of the motor body 3 drives the winding wheel 8 to rotate. The winding wheel 8 winds up or unwinds the rope to drive the window to rise or fall. During the winding and unwinding process, the rope is guided within the sealing tube 10 and passes between multiple limit wheels 15. Each limit wheel 15 is rotatably connected to a limit plate 14 that can slide within the mounting box 12, and the limit plate 14 is constantly subjected to the elastic pushing action of spring 13. When the local diameter of the rope changes due to tolerance or wear, it will generate radial compressive force when passing through the limit wheel 15. This force is transmitted through the limit plate 14 and compresses the spring 13, causing the channel spacing between the limit wheels 15 to increase adaptively, thereby ensuring that rope segments of different thicknesses can pass smoothly and effectively preventing jamming during operation.

[0039] Secondly, when the device needs to be disassembled and maintained, the adjusting bolt 18 can be rotated to cause axial displacement within the insert rod 16, thereby retracting the conical block 19. As the conical block 19 disengages from the arc plate 20, the locking force acting on the locking block 21 disappears, allowing the locking block 21 to disengage from the slot of the mounting base 5, thus releasing the locking state between the mounting shell 1 and the connecting shell 2, achieving convenient and quick disassembly.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
