Description

Technical Field

[0001] This utility model relates to a spool for a window regulator. Background Technology

[0002] The spool is a core component of the motor drive system. In Tesla's three-tooth motor, its compatibility and smooth operation directly affect the overall performance of the motor. Existing spools designed for this type of motor have rigid contact between the teeth, resulting in violent tooth collisions during motor start-up and shutdown, generating significant noise and impacting the user experience. Furthermore, some spools lack sufficient fitting precision, leading to accelerated tooth wear and decreased transmission efficiency with prolonged use, making it difficult to meet the motor's requirements for high efficiency and low noise. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spool for a glass lifter, which has a simple structure, stable and reliable positioning, and good performance.

[0004] To achieve the above objectives, this utility model provides a wire wheel for a window regulator, comprising a wheel body, a connecting through hole at the center of the wheel body, a wire routing groove on the outer peripheral wall of the wheel body, and wire end grooves on both end faces of the wheel body, the wire end grooves communicating with the wire routing grooves. Three connecting posts for cooperating with a three-tooth motor are provided on one end face of the wheel body, the three connecting posts being equidistantly distributed on the end face of the wheel body. A buffer pad is also fitted on the wheel body, and a pad wall is provided on the buffer pad corresponding to the position of the connecting post.

[0005] The benefits of this design are as follows: The three equidistant connecting posts on the wheel's end face precisely match the three-tooth motor. This equidistant design ensures even stress distribution on the connecting posts, preventing loosening caused by localized stress concentration. It guarantees that the wheel and motor maintain coaxiality during transmission, thus ensuring smooth cable routing within the window regulator's cable tray and preventing cable jamming or misalignment due to wheel offset. This meets the structural stability requirements of the window regulator during long-term, high-frequency operation. The buffer pad's walls are positioned corresponding to the connecting posts, cushioning the rigid collisions between the motor and connecting posts during transmission, reducing noise and improving quietness in automotive and other applications. Simultaneously, the pad walls isolate the connecting posts from direct metal-to-metal contact with the motor teeth, reducing frictional loss and preventing increased transmission clearance due to long-term wear. This extends the lifespan of the wheel and motor, reducing equipment maintenance frequency and costs.

[0006] As a further feature of this invention, the wheel body is provided with reinforcing ribs between adjacent connecting columns, and the curvature of the reinforcing ribs is the same as the curvature of the wheel body outline.

[0007] The beneficial effects of this design are as follows: The reinforcing ribs between adjacent connecting posts can precisely absorb the forces transmitted when the connecting posts engage with the three-tooth motor, distributing localized stress to the ribs and the entire wheel body. This prevents cracking or deformation due to stress concentration around the connecting posts, significantly improving the wheel's structural load-bearing capacity. Furthermore, the rib curvature matches the wheel's contour, adapting to the overall stress characteristics of the wheel and preventing additional weak points caused by structural abruptness. It also enhances the rigidity of the wheel's end face, reducing vibration and deformation during motor transmission, ensuring long-term stable transmission of the wheel, and further extending its service life.

[0008] As a further feature of this invention, the wheel body edge is provided with connecting ribs between adjacent connecting posts, and the curvature of the connecting ribs is the same as the curvature of the wheel body outline.

[0009] The beneficial effects of this design are as follows: The connecting ribs between adjacent connecting posts along the wheel's edge can directly bear the radial force and torque generated when the connecting posts and the three-tooth motor are engaged in transmission. This disperses locally concentrated stress to the ribs and the wheel's edge as a whole, effectively preventing cracking and deformation of the wheel around the connecting posts due to overload, and significantly improving the wheel's structural load-bearing strength. Furthermore, the rib curvature matches the wheel's contour, perfectly adapting to the overall wheel structure and preventing weak points caused by structural abruptness. It also further strengthens the rigidity of the wheel's edge, reducing vibration and deformation during motor transmission, ensuring long-term stable transmission of the reel, and meeting the stability requirements of the three-legged pedestal reel structure.

[0010] As a further feature of this utility model, the wheel body has a hollow groove between the connecting rib and the reinforcing rib, and a cavity is provided between the connecting through hole and the reinforcing rib.

[0011] The advantages of this design are as follows: The wheel body features a perforated groove between the connecting rib and the reinforcing rib, and a cavity between the connecting through-hole and the reinforcing rib. Both structures avoid critical stress areas. The connecting and reinforcing ribs ensure the core load-bearing strength of the wheel body, while the perforated groove and cavity precisely eliminate unnecessary redundant material. This significantly reduces the weight of the wheel body without compromising structural stability, achieving a lightweight design. This approach reduces the load on the motor from the wheel itself, improving motor transmission efficiency, and also reduces energy consumption during window regulator operation, aligning with the design goals of the three-legged tripod wheel structure for motor adaptation and efficient operation.

[0013] This utility model provides an embodiment of a reel for a window regulator, such as... Figures 1 to 2 As shown, the device includes a wheel body 1 with a connecting through hole 11 at its center. A cable routing groove 12 is provided on the outer peripheral wall of the wheel body 1. Cable end grooves 13 are also provided on both end faces of the wheel body 1, communicating with the cable routing grooves 12. Three connecting posts 2 for cooperating with a three-tooth motor are provided on one end face of the wheel body 1. The three connecting posts 2 are equidistantly distributed on the end face of the wheel body 1. A buffer pad 3 is also provided on the wheel body 1, with pad walls 31 corresponding to the positions of the connecting posts 2. The advantages of this design are: the three equidistantly distributed connecting posts 2 on the end face of the wheel body 1 are precisely matched with the three-tooth motor; the equidistant design ensures uniform force on the connecting posts 2, avoiding loosening caused by localized stress concentration; and ensuring that the wheel body 1 and the motor maintain coaxiality during transmission. This, in turn, ensures smooth cable winding and unwinding within the cable routing groove 12 of the window regulator, preventing cable jamming or misalignment due to wheel body 1 offset, thus meeting the structural stability requirements of the window regulator for long-term, high-frequency operation. The cushioning pad 3 has a corresponding wall 31 for the connecting column 2. When the motor and the connecting column 2 are in operation, the cushioning pad can buffer the rigid collision between them, reduce the noise generated by the collision, and improve the quietness of use in automotive and other scenarios. At the same time, the cushioning pad 31 isolates the connecting column 2 from the direct metal contact with the motor teeth, reduces friction loss, avoids the increase in transmission clearance due to long-term wear, extends the service life of the wheel body 1 and the motor, and reduces the frequency and cost of equipment maintenance.

[0014] As a further feature of this invention, the wheel body 1 is provided with reinforcing ribs 14 between adjacent connecting posts 2, and the curvature of the reinforcing ribs 14 is the same as the curvature of the wheel body 1. The beneficial effects of this design are: the reinforcing ribs 14 between adjacent connecting posts 2 can accurately bear the force transmitted when the connecting posts 2 cooperate with the three-tooth motor, dispersing the localized force to the ribs and the wheel body 1 as a whole, preventing cracking or deformation due to stress concentration around the connecting posts 2, and significantly improving the structural load-bearing capacity of the wheel body 1. Furthermore, the curvature of the ribs is consistent with the contour of the wheel body 1, adapting to the overall stress characteristics of the wheel body 1, avoiding additional weak points due to structural abruptness, while also enhancing the rigidity of the wheel body 1 end face, reducing vibration deformation of the wheel body 1 during motor transmission, ensuring long-term stable transmission of the wheel, and further extending its service life.

[0015] As a further feature of this invention, a connecting rib 15 is provided between adjacent connecting posts 2 along the edge of the wheel body 1. The curvature of the connecting rib 15 is the same as the curvature of the wheel body 1's outline. The beneficial effects of this design are: the connecting rib 15 between adjacent connecting posts 2 along the edge of the wheel body 1 can directly bear the radial force and torque generated when the connecting posts 2 cooperate with the three-tooth motor for transmission, dispersing locally concentrated stress to the rib and the overall edge of the wheel body 1. This effectively prevents cracking and deformation of the wheel body 1 around the connecting posts 2 due to overload, significantly improving the structural load-bearing strength of the wheel body 1. Furthermore, the rib curvature is consistent with the outline of the wheel body 1, perfectly adapting to the overall structural shape of the wheel body 1, avoiding weak points due to structural abruptness, and further strengthening the rigidity of the wheel body 1's edge, reducing vibration deformation of the wheel body 1 during motor transmission, ensuring long-term stable transmission of the reel, and meeting the stability requirements of the three-legged tripod reel structure.

[0016] As a further feature of this invention, the wheel body 1 has a hollow groove 16 between the connecting rib 15 and the reinforcing rib 14, and a cavity 17 between the connecting through hole 11 and the reinforcing rib 14. The advantages of this design are: the hollow groove 16 between the connecting rib 15 and the reinforcing rib 14, and the cavity between the connecting through hole 11 and the reinforcing rib 14, both avoid critical stress areas. The connecting rib 15 and the reinforcing rib 14 ensure the core load-bearing strength of the wheel body 1, while the hollow groove 16 and the cavity precisely eliminate unnecessary redundant material. This significantly reduces the weight of the wheel body 1 without weakening structural stability, achieving a lightweight design. This not only reduces the load on the motor from the wheel itself, improving motor transmission efficiency, but also reduces energy consumption during the operation of the window regulator, aligning with the design goal of adapting the three-legged pedestal wheel structure to the motor and pursuing efficient operation.
