Description

Manual type side window roller shutter device Technical Field The present invention relates to a manual side window roller blind arrangement for use at a side window of a motor vehicle for shading sun light. Background The rolling device of the door side window of the motor vehicle is divided into two major types, namely manual rolling device and electric rolling device, and the rolling device of the manual side window comprises a curtain cloth scroll component and a curtain cloth connected with the curtain cloth scroll component, wherein the curtain cloth scroll component is transversely arranged in a door of a vehicle body, and the curtain cloth can be pulled out and unfolded from the curtain cloth scroll component and automatically rolled up by the curtain cloth scroll component. The curtain cloth of the existing manual side window roller shutter device can be transversely unfolded and folded or longitudinally unfolded and folded. When the curtain cloth of the manual side window roller shutter device is of a longitudinal unfolding and folding structure, the manual side window roller shutter device further comprises a supporting rod and an operation unit, wherein the supporting rod can move up and down on the vehicle door and is connected with the middle section of a movable edge of the curtain cloth, and the operation unit is positioned in the vehicle door and can lock and unlock the supporting rod. Therefore, when the curtain cloth is pulled to be unfolded from bottom to top, the supporting rods ascend along with the movable edge strips of the curtain cloth, and after the curtain cloth is unfolded, the supporting rods are positioned under the acting force of the operation unit, so that the supporting rods provide supporting force for the curtain cloth to maintain the unfolded state of the curtain cloth. When the curtain cloth is pulled to be folded from top to bottom, the curtain cloth is folded by applying the folding force to the curtain cloth by the curtain cloth scroll component. The above-mentioned conventional manual side window roller shutter device can provide a roller shutter device for providing a sunshade function for a side window of a motor vehicle, but the operation unit for locking and unlocking the support bar in the manual side window roller shutter device is composed of a plurality of independent components, each component is required to be individually installed in a vehicle door and then combined, and the manual side window roller shutter device is not a modularized mechanism. The aforementioned manual side window roller blind apparatus is inconvenient to install in a vehicle door due to a limited installation space in the vehicle door. In addition, in the operation process of unfolding and folding the curtain cloth, the manual side window roller shutter device needs to additionally operate the locking and unlocking states of the operation unit on the support rod, so that the locking and unlocking actions of the operation unit on the support rod are difficult to be directly switched through the upward pulling or downward pulling action of the curtain cloth, the curtain cloth cannot be stopped along with the pulling, and the problem of inconvenient use exists. Disclosure of Invention The invention aims to solve the technical problems of inconvenient assembly, inconvenient use and the like of the conventional manual side window roller shutter device. The invention provides a manual side window roller shutter device which can be arranged in a door of a vehicle body and comprises a curtain cloth scroll component and a curtain cloth connected with the curtain cloth scroll component, wherein the curtain cloth scroll component can be transversely arranged in the vehicle door, and the curtain cloth can be upwards unfolded by the curtain cloth scroll component to shield a side window of the vehicle door and be downwards rolled into the curtain cloth scroll component: a supporting unit which can be installed in the car door and connected with the edge strip of the curtain cloth, can be pulled upwards along with the curtain cloth to be unfolded and extend out of the car door and support the curtain cloth, and can be retracted into the car door along with the curtain cloth to be folded downwards, and The bidirectional positioner can be arranged in the vehicle door and is connected with the supporting unit, the bidirectional positioner comprises a stopping component under the action of elastic force, the stopping component under the action of elastic force can weaken the acting force on the supporting unit to automatically unlock when the supporting unit moves along with the lifting of the edge strip, and the stopping component under the action of elastic force can apply the acting force on the supporting unit to automatically lock when the supporting unit stops. In the manual side window roller shutter apparatus as described above, the bidirectional positioner includes: The shell is provided wit
