Abstract
Description
Technical Field
[0001] The utility model relates to a manual driving component of a glass lifter. Background Art
[0002] The glass lift is a lifting device for the glass of automobile doors and windows, which is mainly divided into two categories: manual drive parts of glass lifts and manual glass lifts. Manual glass lifts are usually equipped with manual drive parts, steel cables, pulleys, guide rails and slide plates. The slide plates slide with the guide rails, and pulleys are arranged on the upper and lower edges of the slide rails. The manual drive parts drive the slide plates to slide on the guide rails by driving the steel cables, thereby driving the windows to complete the lifting and lowering action through the slide plates. However, the manual drive effect in the existing structure is not good, and it is easy to be unstable, resulting in obstacles to the lifting function, affecting the reliability of the structure. At the same time, in order to prevent the operator from continuing to operate after the glass is lifted or lowered into place, the existing structure has made various limit stops to remind the operator, but these structures are complicated and cumbersome, increasing the cost of the structure and reducing the economic benefits. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a manual drive member for a glass lifter, which has a simple and reliable structure and can achieve self-locking after the glass lifter reaches the top, thereby preventing the operating shaft from continuing to rotate and damaging the structure, and has a good use effect.
[0004] To achieve the above-mentioned purpose, the utility model provides a manual driving member of a glass lifter, comprising a driving seat, the driving seat being provided with a connected wiring groove and an operating groove, the driving seat being further provided with a blocking cover for covering the operating groove, the operating groove being provided with an operating shaft for driving the steel cable to slide, one end of the operating shaft being rotatably matched with the operating groove, and the other end being provided with a positioning platform, the positioning platform being provided with a rotating seat, the blocking cover being arranged outside the rotating seat, the rotating seat extending outward from the blocking cover with a connecting handle for matching with the crank, the rotating seat being provided with a connecting notch, a block being arranged at a position corresponding to the connecting notch on the positioning platform, a first gap and a second gap being arranged between the block and the connecting notch, the rotating seat being sleeved with a spring, the two ends of the spring respectively forming a first contact foot and a second contact foot, the first contact foot being inserted in the first gap, the second contact foot being arranged in the second gap, and the inner circumferential wall of the blocking cover being gap-matched with the outer wall of the spring.
[0005] The beneficial effect of such an arrangement is that, when the rotating seat is operated to rotate, the connecting notch on the rotating seat will contact the spring, causing the spring to compress and tighten. At the same time, during the rotation process, the block is further pushed, thereby driving the operating shaft to rotate, thereby driving the reciprocating movement of the steel cable through the movement of the operating shaft to achieve control of the glass lifting and lowering. When the glass moves to the extreme position, the movement of the glass is blocked, which causes the operator to experience stagnation during operation. At the same time, due to the hysteresis of the rotating seat movement, the spring is no longer subjected to the resistance force, thereby loosening and recovering from the tightened state to the natural state. Moreover, due to the clearance between the inner circumferential wall of the baffle cover and the outer wall of the spring, the outer wall of the spring contacts the inner wall of the baffle cover, increasing the difficulty of free rotation of the rotating table, thereby reminding the operator that it has been rotated into place and not to continue to rotate the handle to avoid damaging the overall structure. This structure is simple, easy to operate, and convenient to use. It can immediately remind the operator to rotate into place to avoid damaging the structure, and has a good use effect.
[0006] As a further configuration of the present invention, the angle between the first contact foot and the second contact foot is 103-105°.
[0007] The beneficial effect of such arrangement is that it avoids the angles of the two contact feet being too large, so that when the rotating seat rotates to tighten the compression spring, the spring loosens prematurely or is not compressed and tightened in place, affecting the use effect of the structure. At the same time, the structure is simple and has good use effect.
[0008] As a further configuration of the utility model, a resistance flange is provided on the driving seat in the circumferential direction of the operating shaft, a connecting flange is provided on the blocking cover corresponding to the resistance flange position, a folded edge is provided on the peripheral wall of the connecting flange, and the folded edge is bent and abuts against the rear end surface of the resistance flange of the driving seat.
[0009] The beneficial effect of such arrangement is that the reliability of the connection is further improved, and at the same time, the blocking cover and the driving seat can be pre-positioned, which facilitates the subsequent installation operation of fastening screws. At the same time, the structure is simple, the operation is convenient, and it has a good use effect.
[0010] As a further configuration of the utility model, a positioning protrusion and a positioning groove are further provided between the abutting flange and the connecting flange, and the positioning protrusion and the positioning groove are configured to be snap-connected.
[0011] The beneficial effect of such arrangement is that it is convenient to position the cover and to fasten it by folding the edge. At the same time, the cooperation between the positioning protrusion and the positioning groove can limit the circumferential rotation of the cover and the drive seat, thereby further improving the stability of the structure.
[0012] As a further configuration of the utility model, the connecting flange of the blocking cover is provided with three connecting platforms along the circumferential direction, the connecting platforms are provided with connecting screws for connecting with the door sheet metal, and supporting ribs are provided between the connecting platforms and the connecting flange.
[0013] The beneficial effect of such arrangement is that the connection is more stable and reliable, and structural deformation is avoided. At the same time, the structure is simple and has good use effect.
[0014] As a further configuration of the utility model, a reinforcing rib is connected between the abutting flange and the driving seat.
[0015] The beneficial effect of such arrangement is that, through such arrangement, the overall strength of the structure is effectively improved, the stability of the structure is ensured, and good use effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As a further configuration of this embodiment, a positioning protrusion 14 and a positioning groove 26 are further provided between the abutting flange 12 and the connecting flange 21, and the positioning protrusion 14 and the positioning groove 26 are configured for clamping. The beneficial effect of such configuration is that, through such configuration, it is convenient to position the stop cover and to fasten the folded edge, and at the same time, the cooperation between the positioning protrusion 14 and the positioning groove 26 realizes the limitation of the circumferential rotation of the stop cover and the driving seat, and further improves the stability of the structure in use.
[0024] As a further configuration of this embodiment, the connection flange 21 of the blocking cover 2 is provided with three connection platforms 23 along the circumferential direction, the connection platforms 23 are provided with connection screws 24 for connecting with the door sheet metal, and support ribs 25 are provided between the connection platforms 23 and the connection flange 21. The beneficial effect of this configuration is that through this configuration, the connection is more stable and reliable, and structural deformation is avoided. At the same time, the structure is simple and has a good use effect.
[0025] As a further configuration of this embodiment, a reinforcing rib 13 is connected between the abutting flange 12 and the driving seat 1. The beneficial effect of this configuration is that the overall strength of the structure is effectively improved, the stability of the structure is ensured, and a good use effect is achieved.
