Abstract
The invention discloses a glass lifter which comprises a guide rail, wire guide wheels arranged at two ends of the guide rail, a glass bracket arranged on the guide rail in a sliding manner, a cable, a motor assembly for winding the cable and an installation plate for accommodating the motor assembly, wherein a fixed plate is arranged on the guide rail, a lead screw transmission mechanism is arranged on the fixed plate, the lead screw transmission mechanism comprises a lead screw rod, a lead screw nut arranged on the lead screw rod and a driving mechanism for driving the lead screw rod to rotate, the lead screw nut is fixedly connected with the installation plate, a pressure-sensitive sensor is arranged on the wire guide wheels, the pressure-sensitive sensor is connected with a control unit, and the driving mechanism is connected with the control unit. The glass lifter can realize the tension adjustment of the cable under the condition of not disassembling the glass lifter, and prevents the problem of glass lifting caused by cable looseness.
Description
Technical Field
The invention relates to the field of automobile glass lifters.
Background
Traditional sheave formula glass-frame riser is after long-time the use, and the problem that the cable is lax appears easily takes place, if the cable takes place lax back, leads to glass-frame riser position inaccurate easily, and is unstable during the lift, and the problem that the cable drops from the wire wheel even takes place. Generally, after the cable is loosened, the maintenance can be carried out only by disassembling the lifter and then replacing the cable again, which is very inconvenient. In view of the above problems, there is a need for an improvement of the existing rope wheel type window regulator.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a glass lifter.
The invention is realized by the following technical scheme: the utility model provides a glass lifter, includes the guide rail, set up in wire guide wheel, the slip at guide rail both ends set up glass bracket, cable, the rolling on the guide rail the motor element of cable still including receiving motor element's mounting panel set up the fixed plate on the guide rail, set up screw drive mechanism on this fixed plate, screw drive mechanism includes the screw rod, sets up screw nut, the drive on the screw rod pivoted actuating mechanism, screw nut and mounting panel fixed connection.
In the above technical scheme, one end of the screw nut is provided with a first gear, and an output shaft of the driving mechanism is provided with a second gear matched with the first gear.
The invention has the following beneficial effects: the glass lifter can realize the tension adjustment of the cable under the condition of not disassembling the glass lifter, and prevents the problem of glass lifting caused by cable looseness.
Drawings
FIG. 1 is a schematic structural view of the present invention;
Fig. 2 is a schematic structural diagram of the screw drive mechanism.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments (it should be noted that, in the embodiments, the left and right directions are taken as reference in fig. 1): referring to fig. 1 to 2, the window regulator comprises a guide rail 3, wire guide wheels 2 arranged at two ends of the guide rail 3, a glass bracket 4 arranged on the guide rail 3 in a sliding manner, a cable 1, and a motor assembly 7 for winding the cable 1, wherein the motor assembly 7 comprises a winding wheel and a motor for driving the winding wheel. Still including accomodating motor element 7's mounting panel 6, motor and winding wheel are installed on this mounting panel 6 promptly set up fixed plate 5 on the guide rail 3, set up lead screw drive mechanism 8 on this fixed plate 5, lead screw drive mechanism 8 includes screw rod 80, set up in lead screw nut 82, the drive on the screw rod 80 lead screw rod 80 pivoted actuating mechanism 81, lead screw nut 82 and mounting panel 6 fixed connection. A pressure-sensitive sensor (not shown) is arranged on the guide wheel 2, said pressure-sensitive sensor is connected to a control unit 25, and said drive mechanism 81 is connected to said control unit 25.
A first gear 8a is provided at one end of the screw nut 82, and a second gear 8b that engages with the first gear 8a is provided on the output shaft of the driving mechanism 81. The second gear 8b is driven to rotate by the driving mechanism, which drives the first gear 8a engaged with the second gear 8b to rotate, thereby rotating the wire lever 80. Of course, the manner of driving the wire lever 80 to rotate is not limited to this, and the wire lever 80 may be directly driven by the driving mechanism 81.
A tension value is set in the control unit 25 in advance, and when the tension detected by the pressure sensitive sensor is smaller than the tension value set in advance, the control unit 25 controls the driving mechanism 81 to drive the mounting plate 6 to displace a small distance to the right (the horizontal rightward direction in fig. 1 is the right direction in the embodiment) so that the cable is tightened again. The problems that the rope wheel type glass lifter easily causes inaccurate glass lifting position, is unstable during lifting and even leads a cable to fall off from a wire guide wheel are effectively solved. And when the lifter normally operates, the motor component 7 cannot move in the left-right direction due to the self-locking matching of the screw rod transmission mechanism 8 and the mounting plate 6, so that the performance of the lifter is not influenced during normal operation.
