    Abstract: A multi-lens changing mechanism is disclosed for use in optical scanners; it comprises: (a) a main mechanism having a bottom, first and second sides, and an aperture as an inlet for receiving light, each of the first and second sides having a magnetic means attached thereto; (b) a sliding lens carriage including at least two lenses, the sliding lens carriage being slidable within the main mechanism: and (c) a driving mechanism including a guide rod and a swinging arm. The guide rod is fitted at the bottom of the main mechanism, and is able to move back and forth. The swinging arm has a first end attached to the sliding lens carriage and a second end pivotally mounted to the main mechanism such that the swinging arm will swing when it is driven by the guide rod. The swinging arm of the driving mechanism is constructed such that a vertical movement of the guide rod is convened into a horizontal movement of the sliding lens carriage so as to switch between different lenses Furthermore, the sliding lens carriage has first and second sides opposite the first and second sides of the main mechanism, respectively, each of the first and second sides of the sliding lens carriage is provided with a magnetic means, which, in cooperation with the magnetic means provided on the main mechanism, causes the sliding lens carriage to be firmly but movably attached onto either of the first or second side of the main mechanism so as to effectuate a lens-changing function.

    Abstract translation: 公开了一种用于光学扫描器的多透镜更换机构; 它包括：（a）具有底部，第一和第二侧面以及作为用于接收光的入口的孔的主机构，第一和第二侧中的每一个具有连接到其上的磁性装置; （b）包括至少两个透镜的滑动透镜滑架，所述滑动透镜滑架可在所述主机构内滑动;以及（c）包括导杆和摆臂的驱动机构。 导杆安装在主机构的底部，能够前后移动。 摆臂具有附接到滑动透镜滑架的第一端和可枢转地安装到主机构的第二端，使得当摆动臂被导杆驱动时摆动臂将摆动。 驱动机构的摆动臂构造成使得导杆的垂直运动被转动成滑动透镜滑架的水平运动，以便在不同的透镜之间切换。此外，滑动透镜滑架具有与第一和第二侧相反的第一和第二侧 和主机构的第二侧，滑动透镜滑架的第一和第二侧中的每一个设置有磁性装置，其与设置在主机构上的磁性装置配合使滑动透镜滑架为 牢固但可移动地附接到主机构的第一或第二侧中的任一个上，以实现透镜改变功能。

    Abstract: Disclosed is a device configured for placement in the trunk of a vehicle. Embodiments are used to provide a buffer for protecting the front trunk of a vehicle. The device includes fire retardant/extinguisher powder that releases in the event of a fire caused by collision. In embodiments, the device may consist of one or more layered structures of geometry shapes. The structure consists of vertical geometry cells for storing fire retardant extinguisher powders. Other accessories such as a top covering and handle may apply depending on the embodiments.
