Core elevating mechanism

Abstract

The invention provides a core elevating mechanism comprising a shell, a sliding bar and a driving device, wherein the shell comprises a main frame and a core bracket, an opening is arranged in the main frame, the core bracket is arranged in the opening, two sides of the core bracket and the main frame are integrally molded through elastic arms; the sliding bar is slidably arranged on the main frame and is internally provided with a plurality of Z-shaped pores in parallel, the core bracket is provided with guide columns corresponding to the Z-shaped pores and the guide columns pass through the Z-shaped pores; and the driving device drives the sliding bar to slide on the main frame, one end of the sliding bar is provided with a latch, the driving device comprises a motor and a gear, the gear is meshed with the latch and the motor drives the gear to rotate. The elastic arms are used for replacing the traditional hole-shaft rotation cooperation; only one mold is needed for injection molding, while an optical drive is assembled, the main frame and the core bracket are assembled without manual work, so that one mold is saved, the time for injection molding is reduced, and the manual assembly cost is lowered, therefore, the cost of the optical drive is lowered greatly.

Description

technical field [0001] The invention belongs to the field of optical drive equipment, and in particular relates to a core lifting mechanism. Background technique [0002] In recent years, with the advancement of modern storage technology, optical discs have the advantages of large storage capacity, easy storage, long shelf life, low cost, and data not easily damaged, and users can easily read and store them in optical discs through optical drives. Therefore, the combination of optical drive and optical disk has replaced the traditional magnetic storage medium (magnetic storage medium), and has become one of the indispensable optical storage medium (optical storage medium). In addition, due to fierce competition in the optical drive market, various optical drive manufacturers have to invest a lot of R&D manpower in order to reduce production costs and thereby enhance the competitiveness of optical drives. [0003] For example, the invention patent with the publication number...
