Description

TECHNICAL FIELD

[0001] The present application relates to the field of commercial vehicle glass lifting device, and particularly relates to a rope wheel type automobile glass lifter with a stay wire angle correction mechanism. BACKGROUND

[0002] With the rapid development of the automobile industry, the safety, comfort and convenience of the automobile have become the focus of consumers. As one of the important components to improve the driving and riding experience, the automobile glass lifter not only needs to ensure the smooth and smooth lifting of the door glass, but also needs to have good durability and reliability. The traditional automobile glass lifter is mainly divided into two structural forms of cross arm type and rope wheel type, each of which has its own unique advantages and application scenarios.

[0003] The cross arm type automobile glass lifter, as a classic design, has been widely used in the field of commercial vehicles, especially in the field of commercial vehicles, due to its simple structure, low manufacturing cost and strong durability, especially in the field of commercial vehicles. However, with the diversification of automobile design and the improvement of consumers' requirements for the in-vehicle environment, the cross arm type lifter is not capable of adapting to more complex glass shapes and improving the smoothness of operation.

[0004] The emergence of the rope wheel type automobile glass lifter effectively solves the above problems. The rope wheel type automobile glass lifter transmits power through the winding of the steel wire rope, which not only can adapt to larger curvature glass surfaces and provide more flexible glass lifting solutions, but also significantly improves the sound quality in the vehicle due to the smaller noise generated during operation. Therefore, it has gradually become the preferred choice of mainstream automobile enterprises in the passenger vehicle field. These advantages of the rope wheel type automobile glass lifter make it occupy an increasingly important position in the market.

[0005] However, while the rope wheel type automobile glass lifter brings many advantages, it may also cause the rope wheel type automobile glass lifter to fail due to the twisting or dislodging of the steel wire rope. Specifically, the steel wire rope needs to follow the winding path of the winding wheel groove, and when installing the rope wheel type automobile glass lifter in a commercial vehicle, considering the installation of other components such as the engine inside the commercial vehicle, a baffle is usually added above the winding wheel of the rope wheel type automobile glass lifter for anti-twisting. However, in actual use, the steel wire rope may still dislodge from below the winding wheel of the rope wheel type automobile glass lifter, causing the steel wire rope to twist in the internal structure of the commercial vehicle, thereby directly causing damage to the entire lifting system and failure of the glass lifting function, which not only affects the normal use of the vehicle, but also may pose a potential threat to the safety of passengers in the commercial vehicle.

[0043] In order to better understand the present application, the following will be combined with the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] The present application provides a rope wheel type automobile glass lifter with a pull wire angle correction mechanism, which can solve the problem that the steel wire rope in the rope wheel type automobile glass lifter is easy to come off from the bottom of the winding wheel, resulting in failure of the glass lifting function.

[0045] Referring to Figure 1 The structure diagram of the rope wheel type automobile glass lifter without the pull wire angle correction mechanism, the two ends of the length direction of the lifter guide rail 1 are provided with the winding wheel 14 and the wire outlet wheel 11, and the top of the winding wheel 14 is provided with a cover plate. Due to the interference of the setting of other mechanisms in the automobile, it is difficult to install the same baffle plate on the bottom surface of the winding wheel 14 as on the top surface of the winding wheel 14. Therefore, when the steel wire rope 12 is stretched to the maximum pull distance, the steel wire rope 12 may come off from the bottom of the winding wheel 14.

[0046] Referring to Figure 2 The partial explosion diagram of the wire outlet end of the rope wheel type automobile glass lifter with the pull wire angle correction mechanism, the present application discloses a rope wheel type automobile glass lifter with a pull wire angle correction mechanism, which comprises a lifter guide rail 1 and a pull wire angle correction mechanism. The two ends of the length direction of the lifter guide rail 1 are rotatably provided with the winding wheel 14 and the wire outlet wheel 11, and the winding wheel 14 and the wire outlet wheel 11 are wound with the steel wire rope 12. The movement track of the steel wire rope 12 is parallel to the length direction of the lifter guide rail 1, and the steel wire rope 12 extends from the winding end and changes the movement track direction of the steel wire rope 12 through the wire outlet wheel 11. The pull wire angle correction mechanism is arranged on the lifter guide rail 1 and is specifically arranged at one end close to the wire outlet wheel 11. The pull wire angle correction mechanism can adjust the height of the steel wire rope 12 in the height direction of the lifter guide rail 1, thereby changing the included angle between the steel wire rope 12 and the bottom of the winding wheel 14. Specifically, the higher the height of the steel wire rope 12 at the wire outlet end, the larger the included angle between the steel wire rope 12 and the bottom of the winding wheel 14 when the steel wire rope 12 is wound from the winding wheel 14, thereby reducing the possibility of the steel wire rope 12 coming off from the winding wheel 14. Moreover, since the interval distance between the pull wire angle correction mechanism and the winding wheel 14 is close to the length of the lifter guide rail 1, the interval is relatively far. Therefore, only a small adjustment of the height of the steel wire rope 12 by the pull wire angle correction mechanism can change the included angle between the steel wire rope 12 and the bottom of the winding wheel 14, which is more convenient to use.

[0047] The pull wire angle correction mechanism comprises a fixed boss 2, an adjusting sliding block 3 and a height adjusting member, the fixed boss 2 is installed on the lifting guide rail, the height direction of the fixed boss 2 is parallel to the height direction of the lifter guide rail 1 and is arranged close to the outgoing wire wheel 11; the adjusting sliding block 3 is slidingly arranged on the fixed boss 2, the steel wire rope 12 is arranged on the top surface of the adjusting sliding block 3, the adjusting sliding block 3 can slide along the height direction of the fixed boss 2, thereby adjusting the height position of the steel wire rope 12 at the outgoing wire wheel 11, and thereby changing the included angle of the steel wire rope 12 below the winding wheel 14 at the winding wheel 14; the height adjusting member is connected with the adjusting sliding block 3 and is used for driving the adjusting sliding block 3 to slide along the height direction of the fixed boss 2, so as to facilitate the operator to move the height of the adjusting sliding block 3 on the fixed boss 2, and the use is more convenient.

[0048] As a more preferred embodiment, the fixed boss 2 is integrally injection molded with the lifter guide rail 1, so as to improve the connection strength of the fixed boss 2 and the lifter guide rail 1 and reduce the possibility of accidental fracture of the fixed boss 2 from the lifter guide rail 1.

[0049] In an embodiment of the present application, a matching through hole is formed in the adjusting sliding block 3 for the fixed boss 2 to pass through, the fixed boss 2 passes into the matching through hole so that the adjusting sliding block 3 is sleeved on the fixed boss 2, the length of the height direction of the adjusting sliding block 3, that is, the length of the height direction of the matching through hole, is greater than the height of the fixed boss 2, so that the height distance of the matching through hole becomes the height range that the adjusting sliding block 3 can adjust on the lifter guide rail 1. Threaded through holes of appropriate size are coaxially formed on the same vertical line of the adjusting sliding block 3 and the fixed boss 2, the height adjusting member is specifically an adjusting screw 4, and the adjusting screw 4 is threadedly connected with the threaded through holes on the adjusting sliding block 3 and the fixed boss 2. The adjusting screw 4 simultaneously passes through the threaded through holes on the adjusting sliding block 3 and the fixed boss 2 from bottom to top, and protrudes from the top end of the adjusting sliding block 3, and a supporting and pushing member is arranged at the bottom of the adjusting screw 4, which is used for supporting the adjusting sliding block 3. When the operator rotates the adjusting screw 4, the supporting and pushing member can push the adjusting sliding block 3 to slide along the height direction of the fixed boss 2. This kind of mechanical structure is simple in structure, convenient to operate, and convenient for the operator to control the movement distance of the adjusting screw 4, so as to adjust the angle of the steel wire rope 12 below the winding wheel 14.

[0050] More specifically, in an embodiment of the present application, the supporting and pushing member is specifically a supporting fixed block 41 fixed at the bottom of the adjusting screw 4, and the size of the supporting fixed block 41 is greater than the size of the threaded through hole on the adjusting sliding block 3, so that the supporting fixed block 41 can support and push the adjusting sliding block 3.

[0051] In order to further improve the connection strength between the support fixing block 41 and the adjusting screw 4, and reduce the risk of the support fixing block 41 falling off from the adjusting screw 4 and losing the supporting effect on the adjusting sliding block 3, as a more preferred embodiment, the support fixing block 41 is integrally formed with the adjusting screw 4. The integral manufacturing eliminates the joint weakness in the traditional connection mode, reduces the risk of the support fixing block 41 falling off from the adjusting screw 4, and prolongs the service life of the overall structure. In other embodiments, the design of the adjusting screw 4 and the support fixing block 41 can also be directly replaced by a connecting bolt. The rod part of the connecting bolt is used for threaded connection with the screw hole on the adjusting sliding block 3 and the fixed boss 2. The head part of the connecting bolt is larger than the size of the screw hole, so that the head part of the connecting bolt can support and push the adjusting sliding block 3.

[0052] After the angle correction of the steel wire rope 12 and the bottom of the winding wheel 14 is completed before leaving the factory, in order to reduce the risk of accidental rotation of the adjusting screw 4 during subsequent use, which causes the height of the adjusting sliding block 3 to change, the tensioning angle correction mechanism further includes a locking fixing part 31. The locking fixing part 31 is arranged on the adjusting sliding block 3 and is used for locking the adjusting screw 4 to lock the position of the adjusting sliding block 3. The locking fixing part 31 is spaced apart from the elevator guide rail 1 by a certain distance, and the steel wire rope 12 passes through the space. Therefore, the locking fixing part 31 can also block the edge of the movement track of the steel wire rope 12, thereby playing a role in preventing the steel wire rope 12 from falling off.

[0053] Referring to Figure 3 In an embodiment of the present application, the locking fixing part 31 includes a locking nut. The size of the locking nut is matched with the adjusting screw 4. After the adjusting screw 4 is rotated to the appropriate position, the locking nut is tightened on the adjusting screw 4, thereby achieving the locking of the adjusting screw 4. The locking mode of this mechanical structure is simple in structure and convenient for operators to use.

[0054] In order to further optimize the sliding guide of the adjusting sliding block 3 on the fixed boss 2, the tensioning angle correction mechanism further includes an L-shaped guide bracket 13. The L-shaped guide bracket 13 is installed on the elevator guide rail 1. The cross-sectional size of the L-shaped guide bracket 13 corresponds to the guide hole arranged on the adjusting sliding block 3. When the L-shaped guide bracket 13 is inserted into the guide hole, a simple auxiliary sliding guide rail on the adjusting sliding block 3 is formed. More specifically, in an embodiment of the present application, two L-shaped guide brackets 13 are arranged. The two L-shaped guide brackets 13 are respectively fixed on the two sides of the fixed boss 2 in the length direction. This symmetrical arrangement can further improve the balance of the sliding of the adjusting sliding block 3 on the fixed boss 2, so that the adjusting sliding block 3 can slide vertically and stably, and is more convenient to use.

[0055] In order to improve the connection strength of the L-shaped guide frame 13 and the elevator guide rail 1, the L-shaped guide frame 13 and the elevator guide rail 1 are also made by integral injection molding. The connection gap between the L-shaped guide frame 13 and the elevator guide rail 1 is eliminated, so that the connection of the L-shaped guide frame 13 and the elevator guide rail 1 is more compact, and the possibility of the L-shaped guide frame 13 falling off the elevator guide rail 1 is reduced.

[0056] The rope wheel type automobile glass lifter with the pull wire angle correction mechanism provided in the application has the implementation principle that before the rope wheel type automobile glass lifter is shipped, the steel wire rope 12 is stretched to the maximum pull wire length, and the inclination angle of the steel wire rope 12 and the bottom surface of the winding wheel 14 is evaluated, and when the inclination angle of the steel wire rope 12 and the ground of the winding wheel 14 is less than five degrees, the inclination angle of the steel wire rope 12 and the bottom surface of the winding wheel 14 needs to be corrected. When the correction operation is performed, the operator only needs to twist the adjusting screw 4, so that the adjusting slide block 3 on the fixed boss 2 is driven by the support fixed block 41 at the bottom of the adjusting screw 4, and then the height of the steel wire rope 12 at the outlet wheel 11 end is adjusted, so that the angle of the steel wire rope 12 and the bottom surface of the winding wheel 14 is increased, and the correction work of the angle of the steel wire rope 12 is completed.
