Abstract

A circuit board mounting and demounting device, which is used with a guide and fulcrum device, includes at least one actuation mechanism. The at least one actuation mechanism includes a substrate and a linkage assembly. The substrate is connected to a second circuit board and has at least one second guiding portion. The at least one second guiding portion is guided by the guide and fulcrum device. The linkage assembly includes an actuating rod pivotally disposed on the substrate by a pivot shaft. The actuating rod is pivotable between a first position and a second position and one end of the actuating rod abuts against the guide and fulcrum device. When the actuating rod is pivoted from the first position to the second position, the substrate is moved through the at least one second guiding portion along a guiding direction of the at least one guide and fulcrum device.

Dependent claims

A circuit board mounting and demounting device, which is used with at least one guide and fulcrum device, comprising at least one actuation mechanism, wherein the at least one actuation mechanism comprises:

a substrate adapted to fixedly connect to a second circuit board and having at least one second guiding portion for being guided by the at least one guide and fulcrum device;
and a linkage assembly comprising an actuating rod and a pivot shaft, wherein the actuating rod is pivotally disposed on the substrate by the pivot shaft and is pivotable between a first position and a second position;
when one end of the actuating rod abuts against the at least one guide and fulcrum device and the actuating rod is pivoted between the first position and the second position with the pivot shaft as a fulcrum, the substrate is movable in a guiding direction of the at least one guide and fulcrum device;
and the actuating rod comprises a wrench element and a linkage element;
the linkage element has a pivoting portion and a shank portion which are connected to each other;
the pivot shaft pivotally passes through the pivoting portion and the substrate;
the shank portion has a linkage aperture;
one end of the wrench element is pivotally connected to the substrate and is driven by the actuating rod when the actuating rod pivots;
the wrench element has a linkage protrusion which passes through the linkage aperture;
when the actuating rod is pivoted from the first position to the second position, the linkage protrusion of the wrench element is driven to slide along the linkage aperture, thereby driving the linkage element to pivot the actuating rod from the first position to the second position with the pivot shaft as the fulcrum.

7 more elements

A data processing device, comprising:

at least one guide and fulcrum device comprising at least one first guiding portion and a post portion;
the at least one guide and fulcrum device is located at a fixed position relative to a first circuit board;
a circuit board mounting and demounting device comprising at least one actuation mechanism, wherein the at least one actuation mechanism comprises a substrate and a linkage assembly;
the substrate is adapted to fixedly connect to a second circuit board and has at least one second guiding portion;
the at least one second guiding portion is adapted to engage with the at least one first guiding portion and the at least one second guiding portion is adapted to guide by the at least one first guiding portion;
the linkage assembly comprises an actuating rod and a pivot shaft, wherein the actuating rod is pivotally disposed on the substrate by the pivot shaft and is pivotable between a first position and a second position;
the actuating rod has a notch portion;
when the actuating rod is pivoted from the first position to the second position, the notch portion is in contact with the post portion and applies a force on the post portion, and the substrate is driven to move from a third position to a fourth position through the at least one second guiding portion along a guiding direction of the at least one first guiding portion;
when the substrate is located at the fourth position, the second circuit board is combined with the first circuit board;
and the two first guiding portions are dowel pins;
the two first guiding portions are disposed at an interval and the post portion is located between the two first guiding portions;
the two second guiding portions are disposed at an interval and are tracks extending in a same direction;
a distance of the interval of the two second guiding portions is equal to a distance of the interval of the two first guiding portions;
the two second guiding portions are adapted to engage with the two first guiding portions.
