  • Publication number: 20200100376
    Abstract: Embodiments disclosed herein provide an apparatus to enable smooth and safe assembly of functional modules to computer chassis. The apparatus includes a chassis and a pair of racks mounted to the chassis. Each rack has a plurality of gear teeth formed thereon. A module having a housing is slidably coupled to the chassis and disposed between the pair of racks. A pair of gear pinions are rotatably mounted to the housing and meshed to the gear teeth of one of the racks. A damping member is coupled between each gear pinion and the housing. A sliding movement of the housing relative to the chassis rotates the pair of gear pinions to roll over along the gear teeth. During the sliding movement of the housing, the damping member exerts a resistance force against the housing, to reduce the movement speed of the housing.
