Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In this specification, the pulley assembly described in this specification means an upper pulley assembly in a window winder, since the upper pulley assembly in a window winder receives most of the force. For convenience of description and clarity, the inside of the pulley block described in this specification is the side closer to the window winder with respect to the window winder, while the outside of the pulley block faces the side farther from the window winder. The upper and lower portions described in the present specification are the upper and lower portions with respect to the drawings, and specifically, reference may be made to the symbols in the drawings. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 is a schematic view of a force analysis of a rotating shaft. Referring to fig. 1, a cable is provided on a pulley block provided on a rotation shaft. When the gravity of the cable is denoted by F, the force applied to the rotating shaft is 2F at this time because both sides of the rotating shaft bear the gravity F of the cable.
For a PP + GF 30% plastic material, the deformation of this material at 130 degrees and 1.8MPa is 0.22 mm. In the case where the rotary shaft is made of such a material and the weight of the cable is about 100N, the amount of deformation of the rotary shaft having a diameter of about 12mm is calculated according to the following equation:
S＝πr2＝3.14*36＝113.04mm2(1)
M＝2*100/113.04＝2.2606N/mm2(2)
deformation 2.26/1.8 0.22-0.276 mm (3)
Wherein S represents a cross-sectional area of the rotating shaft; m represents the force on the cross section of the rotating shaft; the calculated amount of deformation is an unrecoverable deformation, and therefore the rotating shaft made of the plastic material described above may be deformed by a large amount, which may affect the service life of the rotating shaft and may degrade the user's experience in using the window regulator and the vehicle.
FIG. 2 is a diagram illustrating a window winder according to one embodiment of the present invention; fig. 3A and 3B are front and side views of the reinforcing component of fig. 2.
Referring to fig. 2 and 3A and 3B, window winder 100 includes a window winder body 110, a pulley assembly, and a reinforcing member 130. Window winder body 110 provides most of the weight of window winder 100 as a support frame for window winder 100. The window regulator body 110 is provided with a guide rail for regulating a window and is fixed to a vehicle body. The window regulator body 110 includes a portion corresponding to the pulley block, an upper portion of the portion corresponding to the pulley block, and a lower portion of the portion corresponding to the pulley block, the lower portion corresponding to a portion in contact with the lower end of the reinforcing member 130.
The pulley assembly comprises a rotating shaft 121 and a pulley block 122, a cable is arranged on the pulley block 122, and the pulley block 122 can rotate relative to the rotating shaft 121 so as to drive the cable arranged on the pulley block to move, so that the vehicle window can be adjusted and moved up and down. The rotation shaft 121 is fixed to the window regulator body 110.
For the window regulator body 110 and the pulley assembly made of plastic, the weight thereof can be reduced by 0.25kg compared with the window regulator body and the pulley assembly made of metal. According to the above analysis, the rotation shaft of the pulley assembly made of plastic material may generate large unrecoverable deformation due to the gravity of the cable, and the window regulator 100 provided by the present invention disperses the force applied to the rotation shaft 121 by providing the reinforcing member 130, thereby reducing the stress on the rotation shaft 121 and preventing the deformation of the rotation shaft 121.
Referring to fig. 2, the reinforcing member 130 is provided on the rotating shaft 121 coaxially with the pulley block 122, and the lower end of the reinforcing member 130 is in contact with the window regulator body 110, so that the force of the cable 123 acting on the pulley block 122 is transmitted to the rotating shaft 121, the rotating shaft 121 in turn transmits the force at least partially to the reinforcing member 130 provided on the rotating shaft 121, and the reinforcing member 130 further transmits the force downward to the window regulator body 110 in contact with the lower end of the reinforcing member 130, whereby the force of the cable 123 and the pulley block 122 acting on the rotating shaft 121 can be dispersed, preventing deformation of the rotating shaft 121.
Referring to fig. 2, the rotation shaft 121 includes a screw 121, wherein the screw 121 passes through the pulley block 122 and the reinforcing member 130 in order and is finally fixed to the window regulator body 110. In this manner, the screw 121 serves as a rotation shaft 121 to support the pulley block 122 and rotate the pulley block 122 relative to the screw 121, thereby moving the cable on the pulley block 122. The bolt 121 is a tapping bolt, which can tap the corresponding positions of the reinforcing member 130 and the window regulator body 110 and is fastened by a nut.
A bushing 124 is disposed between the pulley block 122 and the screw 121 to ensure that the pulley block 122 can rotate relative to the screw 121. The screw 121 and the bushing 124 can support the reinforcing member 130 and the pulley block 122 as a whole with the rotating shaft 121, and the pulley block 122 can rotate with respect to the rotating shaft 121.
The reinforcing member 130 is disposed inside the pulley block 122 to be in close contact with the window regulator body 110, and a lower end 130-1 of the reinforcing member 130 is provided with a flange 131, and the reinforcing member 130 is in contact with the window regulator body 110 through the flange 131. According to an embodiment, the flange 131 extends outwardly from the lower end 130-1 of the reinforcing member 130. A support surface 111 that engages with the flange 131 is provided on the window regulator body 110 to support the flange 131. According to an embodiment, the support surface 111 is realized by a plurality of reinforcing ribs 113 provided on the window regulator body 110. The support surface 111 may comprise a flat, cambered, wave-like surface, wherein the cambered surface may comprise an upwardly curved or downwardly curved surface, which may be adjusted and selected as desired by design. In the embodiment shown in fig. 4, the support surface 211 is planar. In the embodiment shown in fig. 6, the support surface is a downwardly curved arc, i.e. convex. In the embodiment shown in fig. 8, the support surface 211 is an upwardly curved arc, i.e. a concave surface. In addition, the burring 131 may be formed by extending in different directions according to the position of the reinforcing member 130, for example, in the embodiment shown in fig. 4, 6, and 8, the burring 231 and 331 may extend inward from the lower ends 230-1 and 330-1 of the reinforcing members 230 and 330 to fit the support surfaces on the window regulator bodies 210 and 310 when the reinforcing members 230 and 230 are disposed outside the pulley blocks 222 and 322. In addition, as shown in fig. 2 to 4, the reinforcing members 230, 330, and 430 may be disposed outside the pulley blocks 222, 322, and 422. In addition, as shown in fig. 8, the lower end 430-1 of the reinforcing member 430 may not be formed with a burring but directly contact the window regulator body 110 by virtue of its own thickness. The embodiments of fig. 4, 6 and 8 will be described in detail below.
In the embodiment shown in fig. 2, the reinforcing member 130 is disposed inside the pulley block 122 and has a flange 131 extending outward at its lower end 130-1, the flange 131 is flat, and the support surface 111 on the window regulator body 110 has a flat surface that mates with the flange 131. Wherein the support surface 131 is realized by a plurality of reinforcing ribs 113 provided on the window regulator body 110, that is, the support surface 111 is realized by making the plurality of reinforcing ribs 113 have upper ends on the same horizontal plane. The upper end of the reinforcing member 130 also has an outwardly extending flange having a smaller width.
When mounting, the bushing 124 is disposed inside the pulley block 122, and screws are sequentially passed through the bushing 124 and break the reinforcing member 130 placed inside the pulley block 122 and then fixed to the corresponding position of the window regulator body 110. Finally, the bolt is fixed on the other side of the window regulator body 110 through a gong drum. The cable 123 is then mounted on the pulley block 122. This is done. The pulley block 122 can rotate relative to the screw 121 via the bushing 124 and move the cable 123 disposed thereon. The force of the cable 123 and the pulley block 122 acting on the screw 121 can be at least partially dispersed to the reinforcing member 130 coaxially provided on the screw 121, the reinforcing member 130 transmits the force to the support surface 111 on the window regulator body 110 which the flange 131 of the lower end 130-1 thereof contacts, and the support surface 111 disperses the force to the plurality of reinforcing ribs, thereby reducing the force applied to the screw 121, reducing the force applied by the screw 121 to the lower portion of the pulley block 122 which contacts therebelow, reducing the deformation of the pulley block 122, and increasing the service life of the window regulator 100.
FIG. 4 is a schematic diagram illustrating a window winder 200 according to another embodiment of the present invention; fig. 5A and 5B are schematic views illustrating the reinforcing member 230 of fig. 4.
Referring to fig. 4, 5A, and 5B, window regulator 200 includes a window regulator body 210, and window regulator body 110 includes a portion corresponding to the pulley block, an upper portion of the portion corresponding to the pulley block, and a lower portion of the portion corresponding to the pulley block, the lower portion corresponding to a portion in contact with the lower end of reinforcing member 130. Portions of the window winder body 210 above the portion corresponding to the pulley block and the portion corresponding to the pulley block are similar to the window winder body 110 described with reference to fig. 2, and since the shape of the structural support surface 211 of the window winder body 210 shown in fig. 4 is different from the support surface 111 described with reference to fig. 2, the portion below the window winder body 210 shown in fig. 4 is different from that described with reference to fig. 2, that is, the structure of the reinforcing rib 213 is different from the reinforcing rib 113 of the window winder body 110 described with reference to fig. 2 (described in detail below). In the embodiment shown in fig. 4, window regulator body 210 is provided with a projection 224 at a position of the axis of rotation of pulley block 222 to form a rotation axis in cooperation with a flange 221 provided on reinforcing member 230 (described in detail below).

As indicated above, the shape of the support surface 211 and the cuff 231 may be adjusted and selected according to design requirements, for example, as may be seen in the embodiments shown in FIGS. 2, 6 and 8.
On the window regulator body 210, the support surface 211 is implemented by a plurality of reinforcing ribs 213, for example, the plurality of reinforcing ribs 213 may be wired to present the upper end of an arc shape curved downward to implement the support surface 211 as shown in fig. 4.
When installed, the flange 221 of the reinforcing member 230 is extended into the inside of the pulley block 222 and mounted outside the boss 224, and is snapped outside the boss 224. A screw 240 is then inserted through the fastening holes 232 and 212 to fix the reinforcement member 230 to the window regulator body 230. Cable 223 is then mounted on pulley block 222.

Referring to fig. 8, 9A and 9B, the window regulator 400 includes a window regulator body 410, the window regulator body 410 includes a portion corresponding to the pulley block 422, and upper and lower portions of the portion of the pulley block 422, the portion corresponding to the pulley block 422 may be the same as the structure described with reference to fig. 6, and the upper portion may be adjusted as needed, and the lower portion may be adjusted according to the support surface 411. Window regulator 400 further includes pulley block 422, flange 421 of reinforcing member 430, cable 423, screw 440, through hole 433, and boss 424, which structures may be the same as described with reference to fig. 6. The following describes different portions of the reinforcing member 430 from the reinforcing member 430 described with reference to fig. 6.
According to the present embodiment, the lower end 430-1 of the reinforcing member 430 is not provided with the burring, but the lower end 430-1 directly contacts the support surface 411 of the window regulator body 410. The lower end 430-1 of the reinforcing member 430 forms a contact surface with the support surface 411 by its own thickness, thereby transmitting force to the window regulator body 410. The support surface 411 has a concave surface curved upward, and thus the lower end 430-1 of the reinforcing member 430 has a curved edge that mates with the support surface. The support surface 411 is realized by a reinforcement 413.
The edge of the lower end 430-1 is provided with a protrusion 431 and correspondingly the contact surface 411 is provided with a recess (not shown) corresponding to the protrusion such that the protrusion 431 and the recess cooperate to provide good fixed contact of the lower end 430-1 with the support surface 411 preventing the reinforcement member 430 from rotating as well as the pulley block 422 rotates. The present invention is not limited thereto and the edge of the lower end 430-1 may have other configurations.
The mounting process of the present embodiment is the same as the mounting process described with reference to fig. 6.
When the reinforcing member is provided inside the pulley block, the reinforcing member may be embedded on the window regulator body as an insert by a molding process. Or may be mounted on the window winder body according to the description above.
As described above, the reinforcing member may be provided in parallel on the inner side or the outer side of the pulley block as needed, the reinforcing member may be embedded in or assembled to the window regulator body as needed, a flange may be provided on the reinforcing member and a corresponding projection may be provided on the window regulator body as a rotation shaft of the pulley block or both the reinforcing member and the pulley block may be provided on the screw and a bushing may be provided between the pulley block and the screw to achieve rotation of the pulley block with respect to the screw, the reinforcing member may be fixed to the window regulator body coaxially with the pulley block or fixed to the window regulator body offset from the rotation shaft, and the lower end of the reinforcing member may directly contact the support surface and may contact the support surface through the burring. These may be adjusted and selected differently according to design requirements.
The invention further provides a vehicle comprising the window winder.
In summary, the present invention provides a window regulator for a vehicle, comprising: a window regulator body; the pulley assembly comprises a rotating shaft fixed to the window regulator body and a pulley block which is arranged on the rotating shaft and rotates relative to the rotating shaft so as to drive the cable to move; and a reinforcing member provided on the rotating shaft coaxially with the pulley block and having a lower end in contact with the window regulator body to disperse a force on the rotating shaft and the pulley block at least partially downward to the window regulator body with the lower end in contact. Thus, the force applied to the rotating shaft by the pulley block can be transmitted at least partially to the reinforcing member by the reinforcing member provided coaxially with the pulley block on the rotating shaft, so that the dispersed force is transmitted to the window regulator body in contact with the lower end of the reinforcing member by the reinforcing member to be transmitted to the vehicle. Therefore, the force born by the rotating shaft due to the pulley block and the cable on the pulley block can be reduced, and even for the window regulator made of plastic, the stress of the rotating shaft can be reduced, so that the deformation of the rotating shaft is reduced, and the service life of the rotating shaft is prolonged.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
