Abstract

A push button assembly disposed on a cover has a push button hole, and includes a holder, a latch, a resilient member, and pushing bracket. The holder forms a chute with the cover. The holder has an abutting plate and a retaining structure. The abutting plate and the retaining structure are respectively located at first and second ends of the chute. The latch is slidably disposed in the chute and faces the push button hole. The retaining structure can prevent the latch from leaving the chute from the second end. The resilient member is disposed in the chute and compressed between the abutting plate and the latch. The pushing bracket is connected to the latch and extends away from the cover. The disclosure further discloses a chassis applying the push button assembly and an operating method of the chassis.

Claims12

Dependent claims

A push button assembly disposed on a cover, the cover having a push button hole, the push button assembly comprising:

a holder fixed to the cover and forming a chute with the cover, the holder having an abutting plate and a retaining structure, the chute having a first end and a second end, wherein the abutting plate is located at the first end, and the retaining structure is located in the chute, the chute is parallel to a sliding direction, and the holder further has a passing hole;
a latch slidably disposed in the chute and aligned with the push button hole, wherein the retaining structure blocks the latch, so as to prevent the latch from leaving the chute from the second end;
a resilient member disposed in the chute and compressed between the abutting plate and the latch;
a pushing bracket connected to the latch and substantially extending away from the cover wherein the pushing bracket comprises:
a passing portion connected to the latch and passing through the passing hole;
and
a pushing portion connected to the passing portion and substantially parallel to the sliding direction;
wherein the retaining structure is a slotted hole extending along the sliding direction, the latch has a resilient arm and a distal end of the resilient arm is slidably engaged with the slotted hole;
and
wherein the resilient member is a spring, the abutting plate has a through hole, and the latching further has a column which extends towards the first end and passes through the through hole, and the spring sleeved onto the column.

7 more elements

A chassis for accommodating a storage device, the chassis comprising:

a base, wherein the storage device is slidably disposed on the base along a sliding direction;
a cover connected to the base to form an entrance and an accommodating space;
a partition disposed on the base and adjacent to a sidewall of the storage device, wherein the partition comprises a stopping portion located over a top surface of the storage device;
an engaging bracket fixed to the sidewall and comprising a bent portion which is located over the storage device, faces toward the entrance, and bent upwards relative to the storage device, wherein the stopping portion blocks between a distal end of the bent portion and the entrance;
and
a push button assembly fixed on the cover and comprising a pushing bracket which substantially extends away from the cover and is capable of sliding relative to the cover along the sliding direction, wherein when the pushing bracket slides toward the entrance to push the bent portion, the bent portion is deformed toward the storage device to escape from the blocking of the stopping portion.
