Description

Window lift mechanism

This creation is about the window lift mechanism, especially a fast and structurally stable window lift mechanism.

The existing window lifting mechanism is mainly divided into a tooth plate type and a sliding rail type. The tooth plate type window lifting mechanism shifts the window by the rotation of the tooth plate, and the mechanism itself has lower manufacturing precision requirements, but the mechanism occupies space and the mechanism swings. The extra space required is large and therefore not suitable for all doors. The slide type window lifting mechanism moves the slider to move along the curved slide rail by the cable to move the window, so the mechanism occupies a small space, and the additional space required for the mechanism to operate is small. However, the rail-type window lifting mechanism has a higher manufacturing precision requirement, and the cable is less easy to assemble than the toothed plate.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The winch 300 is housed in the seat shell 200. The side edge surface of the winch 300 is preferably provided with a screw groove 301 extending spirally around the winch 300 along the side edge surface of the winch 300. The motor 400 is attached to the housing 200. The motor 400 is inserted into the housing 200 and the winch 300 is connected to thereby drive the winch 300 to rotate. The motor 400 and the winch 300 are preferably connected by gears, belts or chains.

Referring to Figures 1, 3, 4 and 6, the loop cord 500 is preferably a loop-shaped cable, but the present invention is not limited thereto, and the cross-sectional diameter of the loop cord 500 preferably matches the inner diameter of the slot 301. A portion of the loop cable 500 is wound around the winch 300 and embedded in the screw groove 301 to be fixed to the winch 300. The loops 500 extend through the respective slots 211a/211b and extend out of the housing 200. Another portion of the loop cord 500 is wrapped around the pulley 120, specifically the loop cable 500 about the pulley 120 for about half a week. Thereby, the loop cable 500 is spanned between the pulley 120 and the winch 300 and the loop cable 500 is rolled by the winch 300 to pull the loop cable 500 cyclically displaced in the longitudinal direction thereof.

The loop cable 500 spans a portion 510a/510b disposed at two intervals between the pulley 120 and the winch 300, wherein one of the line segments 510a contacts the convex surface 103 of the guide plate 100 and is disposed along the arc of the guide plate 100. The other line segment 510b is suspended from the guide plate 100 and passes through the lead frames 140.

The lower limit stop 130 is disposed on the guide plate 100 instead of the slider 600, and therefore does not wobble as the slider 600 moves, so that the lower limit of the slider 600 is positioned more accurately. Since the slider 600 is connected to the window, when the slider 600 lifts the window upward, once the window contacts the upper edge of the frame, the upward movement cannot be continued, so the upper limit block is not required to be set.

When the motor 400 drives the winch 300 to rotate, the winch 300 winds the loop cable 500 onto the winch 300 through one of the slots (211a or 211b), and the winch 300 releases the loop cable 500 through the other slot (211b or 211a). . The motor 400 drives the winch 300 to rotate forwardly and reversely to drive the loop cable 500 to move bidirectionally, thereby driving the slider 600 to move up and down along the slide rail 110 between the top end 101 and the bottom end 102 of the guide plate 100, thereby pushing The window lifts. Positive and negative rotation means that the winch 300 has two opposite directions of rotation and is not limited to a particular direction of rotation.

The housing 210 of the housing case 200 is provided with a cutout 211a/211b to facilitate assembly of the winch 300. The loop cable 500 is first wound around the winch 300 during assembly. When the winch 300 is placed in the casing 210 of the bottom end 102 of the guide plate 100, the loop cable 500 can be laterally placed into each of the missing slots 211a/211b, respectively, and the winch 300 can be positioned to simultaneously tighten the loop cable 500, and the other cover shell When the cover is closed, the assembly can be completed. Therefore, it is not necessary to spend more labor to pass the loop cable 500 out of the seat shell 200, and the loop cable 500 can also assemble the slider 600 in a relaxed state to facilitate assembly.
