Abstract: A housing assembly for a portable electronic device includes a first body, a second body, a first engaging member, a first resilient member and a first housing. The first body has a first space. The second body is installed to the first body and has a first release hole. The first engaging member is movably located in the first space. The first engaging member has at least one first engaging portion. The first resilient member provides a force to the first engaging member to orient the first engaging member toward the first release hole. The first housing is connected to the second body and has at least one first contact portion. When assembling, the first contact portion contacts the first engaging portion. The force of the first resilient member applied to the first engaging member to firmly connect the first housing to the second body.

Abstract: A securing device for a portable electronic device includes a body and a case is mounted to the body. First and second engaging members are respectively connected to two sides of the body. First and second locking members are respectively and movably connected to the two sides of the body and located corresponding to the first and second engaging members. The first locking member includes a first stop and a first recess, and the second locking member includes a second stop and a second recess. The first/second engaging member is stopped by the first/second stop and is movable in the first/second recess to unlock the secured status. A connection member is pivotably connected to the first and second locking members and is movable by operation of the control member to shift the first and second locking members to allow the first and second engaging members to unlock.

Abstract: A locking device includes a body, a first part, an engaging assembly, a link and a locking member. The body has an installation area and the engaging assembly is installed in the installation area and includes a first engaging member and a first resilient member which provides a force to the first engaging member to connect the engaging member to the first part. The link is movably located in the installation area to push the first engaging member to move relative to the first part to release the locked status. The locking member is located in the installation area and has a first recess and an operation end. When the first recess is located corresponding to the first engaging member, the first engaging member is movable in the first recess. When the first recess is located away from the first engaging member, the first part is secured to the body.

Abstract: An operation device for controlling sliding cover of portable electronic product includes first, second and third magnetic members, a transmission unit and an operation unit. The third magnetic member is connected to the transmission unit and includes first and second magnetic polarities. The operation unit drives the transmission unit and the two magnetic members are fixed to the first and second positions of the sliding cover. When the operation unit is operated, the third magnetic member is rotated so that the first magnetic polarity of the third magnetic member is impulsive to the first magnetic member to open the sliding cover, or the first magnetic polarity of the third magnetic member is impulsive to the second magnetic member to close the sliding cover.

Abstract: A case assembly for electronic appliance includes a first case having a plurality of engaging members and each engaging member includes two clamping protrusions. Each clamping protrusion includes a supporting portion and a protruding portion. A space is defined between the two clamping protrusions. A second case includes multiple ports and each port has a shoulder defined in an inside thereof and the shoulder is located corresponding to the protruding portions of the clamping protrusions. Multiple positioning members each have an insertion portion and a head. A transverse width of the opening of the space is smaller than a width of the insertion portion. When the insertion portion of each of the positioning members is inserted into the space corresponding thereto, the clamping protrusions are expanded outward by the positioning member, and the protruding portions are engaged on the shoulder of the second case.
