Description

window lift mechanism

The invention relates to a vehicle window lifting mechanism, especially a lightweight vehicle window lifting mechanism.

With the advancement of modern industry, various manufacturers are constantly striving for perfection in pursuit of making products thinner and smaller with the same function. Therefore, in order to reduce the space occupied by the lifting mechanism, most of the existing window lifting mechanisms use guide rails. The lifting mechanism mainly pulls the steel cable through the driver, thereby pulling the slider to move along the arc guide rail to push the window up and down.

However, in order to take into account the overall structural strength, the general arc-shaped guide rail is mostly made of metal parts, so the addition of parts such as drivers, pulleys and steel cables makes the window lifting mechanism have a certain weight, and also makes the entire door. The weight is also relatively heavy, which leads to a substantial increase in the weight of the entire two-door car or four-door car, thereby affecting energy consumption, speed and production costs. Furthermore, since the metal parts are not easy to be integrally formed, they need to be manufactured in separate parts and then assembled separately, which makes it easy to produce tolerances during assembly.

In view of this, the present inventor aimed at the above-mentioned deficiencies in the prior art, devoted himself to research and combined with the application of theories, and tried his best to solve the above-mentioned problems, which became the goal of the inventor's improvement.

The main purpose of the present invention is to use the metal axle seat to maintain the structural strength, and at the same time reduce the weight significantly through the plastic guide rail, thereby reducing the production cost.

In order to achieve the above object, the present invention provides a vehicle window lifting mechanism, including a guide rail, a shaft seat, a pulley, a driving module and a slider, the shaft seat has an embedded section and a shaft rod, the embedded section is embedded At one end of the guide rail, the shaft rod is exposed to the guide rail and a flange attached to the guide rail extends laterally, the pulley is sleeved on the shaft rod, and the flange is blocked between the pulley and the guide rail, The driving module includes a driver and a hoop, the hoop is wound around the pulley and connected to the driver, the driver is arranged on the guide rail and linked with the hoop to pull the hoop, the slider is arranged on the guide rail, The sliding block is fixedly connected to at least one part of the loop cable and can be pulled by the loop cable to slide along the guide rail.

The present invention also has the following effects: through the integrally formed metal shaft seat, the dimensional accuracy can be effectively controlled and the impact on the structural strength and assembly work error can be avoided during assembly. By setting the mounting seat at the center of the guide rail, the plastic guide rail can be symmetrical up and down, and can be turned over and installed on the left and right sides of the car door universally. The transversal section through the embedded section is non-circular, which can prevent the embedded section from rotating in the guide rail. By means of the concave part arranged on the outer edge of the embedded section, the shaft seat can be restrained longitudinally to prevent it from detaching from the guide rail.

The invention provides a vehicle window lifting mechanism, which is arranged inside the vehicle door and connected to the vehicle window, so as to control the lifting of the vehicle window. Please refer to FIG. 1 to FIG. 5 , which mainly includes a guide rail 10 , a shaft seat 20 , a pulley 30 , a driving module 40 and a slider 50 .

In this embodiment, the guide rail 10 is integrally molded by plastic injection, thereby effectively reducing weight and cost, but the present invention is not limited thereto. For example, the guide rail 10 can also be made of plastic, polymer, or composite , copolymer, reinforced glass fiber, fiber-reinforced plastic (FRP, fiber-reinforced plastic), composite fiber, high-strength fiber or a mixture of at least two of the foregoing. In this embodiment, the guide rail 10 is generally in the shape of a strip, but the present invention is not limited thereto. Preferably, the guide rail 10 is arc-shaped and can match the shape of the door to be accommodated inside the door. A mounting base 11 for the driving module 40 extends from one side of the guide rail 10 . In this embodiment, the mounting seat 11 is located at the center of the guide rail 10, so that the guide rail 10 is symmetrical up and down, that is, the guide rail 10 can be turned upside down and installed in the left and right sides of the door universally, but this The invention is not limited thereto, for example, the mounting seat 11 can also be located at the bottom of the guide rail 10, or be accommodated in the existing space of the car door.

In this embodiment, the number of axle seats 20 and pulleys 30 is two, but the present invention does not limit the number of axle seats 20 and pulleys 30, and the structure of two axle seats 20 and two pulleys 30 in this embodiment and functions are the same, so only a single shaft seat 20 and a single pulley 30 will be further described in detail below.

In this embodiment, the shaft seat 20 is an integrally formed metal part, so as to effectively control the dimensional accuracy, and avoid affecting the structural strength and causing assembly errors during assembly, but the present invention is not limited thereto. In this embodiment, the shaft seat 20 is made by powder metallurgy forming or stamping, but the invention is not limited thereto. For example, the shaft seat 20 can also be formed by forging or machining. The shaft seat 20 has an embedded section 21 and a shaft 22 . The embedded section 21 is embedded in one end of the guide rail 10, that is, the end of the guide rail 10 covers the embedded section 21 and has an embedded hole 13 corresponding to the profile of the embedded section 21 (as shown in Figure 3 and Fig. 4 exploded view). The shaft 22 is exposed from the guide rail 10 and extends laterally with a flange 23 attached to the guide rail 10 . The transverse section of the embedded section 21 is non-circular, so that the embedded section 21 can be prevented from rotating in the guide rail 10 . In this embodiment, the transverse section of the embedded section 21 is hexagonal, but the invention is not limited thereto, as long as the transverse section of the embedded section 21 has at least one plane to prevent rotation. Also, at least one concave portion 211 is provided on the outer edge of the embedded section 21, and there is a distance d (see FIG. 5 ) between the end surface of the embedded section 21 end and the concave portion 211, so that the concave portion 211 can be affected by the concave portion 211. The plastic embedded in the hole 13 restricts the shaft seat 20 longitudinally, so as to prevent the shaft seat 20 from detaching from the guide rail 10 . In this embodiment, the concave portion 211 is a groove surrounding the embedding section 21 , so that the plastic embedded in the embedding hole 13 in the concave portion 211 can be locked evenly without being easily deflected due to torque. However, the present invention is not limited thereto. For example, the concave portion 211 can also be a concave groove of any shape, as long as it can function as a longitudinal stop.

The pulley 30 is sleeved on the shaft 22 , and the flange 23 is blocked between the pulley 30 and the guide rail 10 . In this embodiment, the flange 23 is a circular plate. In this way, the shaft seat 20 can have a better strength structure compared to the plastic, so as to effectively support the pulley 30 to avoid fracture when stressed; and the flange 23 of the shaft seat 20 can connect the pulley 30 and the guide rail 10, so as to prevent the pulley 30 from directly rubbing against the guide rail 10 when rotating and causing wear.

To further illustrate, the vehicle window lifting mechanism of the present invention also includes a stopper 60 . The stopper 60 is longitudinally fixed to the shaft 22 , so that the pulley 30 is limited between the stopper 60 and the flange 23 . In this embodiment, the stopper 60 is a bolt, but the present invention is not limited thereto. For example, the stopper 60 can also be a rivet or a pressing pin. Specifically, a screw hole 221 is defined in the center of the shaft 22 , and the bolt is locked into the screw hole 221 of the shaft 22 . It is worth noting that the head of the bolt is pressed against the end face of the shaft 22 instead of the side of the pulley 30, so that the left and right sides of the pulley 30 are not blocked. The head of the bolt is clamped with the flange 23 of the shaft seat 20 , but there is a certain clearance for the pulley 30 to rotate smoothly.

Please refer to FIG. 1 and FIG. 6 , the driving module 40 includes a casing 41 , a driver 42 , a winch 43 and a hoop 44 . In this embodiment, the driver 42 is a motor. The casing 41 is a cover that is arranged on the mount 11, the winch 43 is housed in the casing 41, the driver 42 is attached to the mount 11 and connected to the winch 43 to drive the winch 43 to rotate, but The present invention is not limited thereto, for example, the driver 42 and the winch 43 may also be connected by gears, belts or chains. The ring cable 44 is a ring-shaped steel cable, but the present invention is not limited thereto. The hoop 44 is looped around each of the pulleys 30 at the upper and lower ends of the guide rail 10, and a part of the hoop 44 is looped and fixed on the winch 43, so that when the driver 42 drives the winch 43 to rotate, it can Let the winch 43 drive and reel the hoop 44 .

Referring again to FIGS. 1 and 2 , the slider 50 is slidably disposed on the guide rail 10 . The sliding block 50 is fixed to at least one part of the hoop 44 and can be pulled by the hoop 44 to slide along the guide rail 10 . The glass system of the vehicle window is installed on the slide block 50 , so that when the slide block 50 is pulled by the hoop 44 and slides along the guide rail 10 , the window can be raised and lowered. Preferably, a limiting block 12 is formed at both ends of the guide rail 10 . Specifically, the limiting block 12 is a plastic block that is integrally molded together with the guide rail 10 , and the limiting block 12 is located on a side of the shaft seat 20 adjacent to the installation seat 11 . In this way, when the sliding block 50 is pulled to either end of the guide rail 10 by the loop rope 44 , the limiting block 12 can serve as a stopping point, thereby preventing the sliding block 50 from directly colliding with the pulley 30 and causing damage.

In summary, the present invention has industrial applicability, novelty and progress, fully meets the requirements for patent application, and should be filed in accordance with the Patent Law. Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can evolve various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and deformations should belong to the protection scope of the patent application for the present invention.
