Description

Technical Field

[0001] The utility model belongs to the technical field of optical drive replacement structures in optical disk libraries, in particular to an optical drive positioning structure and an optical disk library free of screw assembly. Background Art

[0002] Optical discs have become an indispensable information carrier medium in today's information society with their incomparable advantages over traditional recording media, such as large capacity, low cost, standardized data format, easy storage, safety and reliability, convenient use and easy to carry. Optical discs are usually stored in optical disc libraries. In order to facilitate the management of optical discs, they usually need to be classified and placed in groups. Therefore, in the process of burning and reading optical discs, a single optical drive or a single group of optical drives is usually used as a unit. At present, the structural design related to the fixation of optical drives in optical disc libraries mostly uses the screw holes of the optical drive itself for fixed installation, but when tightening the screws, there are certain requirements for the screw torque, otherwise it is easy to cause the optical drive to deform, resulting in optical drive failure or shortened life. This requirement requires professionals and professional tools to replace it when replacing it. After replacement, position accuracy debugging is also required, which greatly increases the time and cost of after-sales maintenance and poor user experience. In addition, the existing standard half-height optical drive has a panel size larger than the sheet metal frame size, presenting a large head and a small rear shape, which means that the insertion and removal of the optical drive can only be assembled by inserting from the front to the back and pulling out from the back to the front. Although the optical drive can be inserted from back to front and pulled out from front to back after the panel is removed, removing the panel will bring the risk of reduced quality and life of the optical drive.

The optical drive module 2 can be positioned in the optical drive frame 1 without using screws, and the disassembly and assembly direction is convenient and easy to replace. The optical drive positioning structure of the present application includes an optical drive rack 1, an optical drive module 2 and a locking mechanism 3, wherein the optical drive rack 1 is used to carry the optical drive module 2 so that the optical drive module 2 is regularly arranged in the optical drive rack 1, and the optical drive rack 1 includes a first side plate 11 and a second side plate 12 arranged opposite to each other, and a plurality of optical drive supports 13 in a symmetrical array are arranged on the inner side surfaces of the first side plate 11 and the second side plate 12, and the optical drive supports 13 on each side are arranged up and down, and four optical drive supports 13 that are symmetrical on the left and right and spaced up and down form a positioning space for positioning the optical drive module 2, and in order to ensure that the optical drive module 2 can be smoothly inserted into and pulled out of the positioning space, a certain gap is left on each side of the upper and lower and left and right assembly cooperation; the front end of the positioning space is a limit outlet 14, and the limit outlet 14 is used to ensure that the optical drive tray 24 can be pulled out from the front end, and the rear end of the positioning space is open, and the openness can be understood as enabling the optical drive module 2 The entrance of the positioning space can be freely inserted, and the optical drive module 2 can be inserted into the positioning space from the opening and pulled out of the positioning space from the opening; the optical drive module 2 includes an optical drive 21, an optical drive front frame 22 and two optical drive side sleeves 23, the two optical drive side sleeves 23 are respectively fixed on the two side walls of the optical drive 21, the vertical distance between the two optical drive side sleeves 23 is not less than the length of the optical drive front frame 22, the height of the optical drive side sleeve 23 is not less than the height of the optical drive front frame 22, that is, the overall external dimensions of the optical drive side sleeve 23 are not less than the dimensions of the optical drive front frame 22, so as to realize the insertion and withdrawal of the optical drive module 2 from the opening of the optical drive rack 1, and the optical drive module 2 is installed in the positioning space through the two optical drive side sleeves 23, which can be understood as realizing the positioning of the optical drive 21 by contacting the optical drive side sleeves 23 with the optical drive support 13; the locking mechanism 3 is arranged at the opening, for locking the optical drive module 2 in the positioning space. The present application does not limit the number of positioning spaces, and multiple positioning spaces may be arranged side by side up and down. An optical drive module 2 may be installed in each positioning space. Each optical drive module 2 is configured with a locking mechanism 3, and the locking mechanism 3 does not make direct contact with the optical drive 21 to avoid deformation of the optical drive, resulting in malfunction of the optical drive or a reduction in its lifespan.

[0052] The present application sets optical drive side covers 23 on both sides of the optical drive, and the optical drive module 2 is installed in the positioning space through the optical drive side covers 23. On the one hand, the optical drive module 2 can be inserted from the back to the front and pulled out from the front to the back, reducing the risk of collision with other structures; on the other hand, the optical drive side covers 23 can enhance the strength and service life of the optical drive 21.

[0053] In the specific embodiment, see Figure 4 , Fig.16 , Fig. 20The position-limiting outlet 14 is limited by two optical drive stop bars 15 connected to the first side plate 11 and the second side plate 12, that is, the two optical drive stop bars 15 arranged up and down and the first side plate 11 and the second side plate 12 arranged left and right together form the position-limiting outlet 14. After the optical drive module 2 is inserted into the positioning space from the rear end, the front frame 22 of the optical drive is close to the optical drive stop bars 15, and the optical drive 21 cannot be pulled out from the position-limiting outlet 14. The optical drive stop bars 15 can determine whether to add a buffer pad according to the fine processing accuracy of the sheet metal process to ensure the positioning accuracy and quality of the optical drive module 2; the optical drive 21 also includes An optical drive tray 24 is movably arranged in the optical drive 21, and is used for carrying an optical disc. The optical drive tray 24 can be pulled out from the limit outlet 14 so as to place an optical disc thereon for storage or to take out an optical disc therefrom. The present application locks the optical drive module 2 in the positioning space through the optical drive stop bar 15 and the locking mechanism 3, and there is no need to perform operations such as tightening screws on the optical drive 21. Not only can the quality of the optical drive 21 be guaranteed, but also when the optical drive module 2 needs to be replaced, it can be directly pulled out from the rear end and the new optical drive module 2 can be installed in the positioning space without the need for further calibration, which is conducive to ensuring the positioning accuracy.

[0054] It should be noted that the optical drive side cover 23 of the present application can be designed to be integrally formed with the optical drive 21 or separately designed from the optical drive 21, but the split design also requires that professionals use special tools to fix the optical drive 21 to the optical drive side cover 23 before leaving the factory. The fixing method can be screw fixing or adhesive fixing, and there is no specific limitation on this.

[0055] See also Figures 1 to 7 In some embodiments, each optical drive side cover 23 includes an extension portion 231, and the extension portion 231 extends a distance to the rear of the optical drive 21; there are two locking mechanisms 3, which are respectively arranged on the two extension portions 231; the following takes one of the locking mechanisms 3 and the corresponding extension portion 231 as an example for description, and the locking mechanism 2 includes a spring clip buckle 31 fixed to the inner side of the extension portion 231 and a fastener 32 arranged beside the spring clip buckle 31; a guide groove 232 is opened on the extension portion 231, and a fastener 32 is arranged on the optical drive frame 1 corresponding to the guide groove 232 A limiting groove 16 is provided; the free end of the spring clip buckle 31 extends into the guide groove 232 and can move along the opening direction of the guide groove 232, such as the free end can extend out of the guide groove 232 or retract into the guide groove 232; by adjusting the fastener 32 of the locking mechanism 3 so that the fastener 32 presses against the spring clip buckle 31, the free end of the spring clip buckle 31 moves outward along the guide groove 232 under the action of the fastener 32 and is clamped into the limiting groove 16, thereby fixing the optical drive module 2 in the positioning space without applying force to the optical drive 21, thereby ensuring the yield of the optical drive.

[0056] Specifically, a mounting block 25 is fixed to the end of the extension portion 231 away from the optical drive 21. The mounting block 25 and the spring clip buckle 31 are both located on the inner side of the optical drive frame 1. A threaded hole running through the mounting block 25 is provided. The fastener 32 is a hand screw. After passing through the threaded hole, the hand screw contacts the spring clip buckle 31. During the process of continuous tightening, the hand screw applies an extruding force to the spring clip buckle 31, causing the spring clip buckle 31 to move toward the direction of the optical drive side sleeve 23 until the free end of the spring clip buckle 31 is inserted into the limiting groove 16. In one embodiment, the spring clip buckle 31 includes a fixed portion 311, a bent portion 312 and a straight portion 313 connected in sequence. The spring clip buckle 31 is fixed to the inner side of the optical drive side cover 23 through the fixed portion 311. The straight portion 313 is located in the guide groove 232. The hand screw contacts the outer side of the bent portion 312 and can press the bent portion 312 outward during the movement. The bent portion 312 can drive the straight portion 313 to snap into the limit groove 16. The spring clip buckle 31 of the present application is fixed to the optical drive side cover 23 and has no contact with the optical drive 21. It will not affect the quality of the optical drive 21 during its force application.

[0057] In the free state, the hand screw does not contact the spring clip buckle 31, and the straight portion 313 of the spring clip buckle 31 is already in the guide groove 232, but has not extended or has not fully extended. When the hand screw is tightened, it contacts the spring clip buckle 31 and presses the spring clip buckle 31 outward, so that the straight portion 313 moves outward along the direction of the guide groove 232 until it is stuck in the limit groove 16, thereby achieving the positioning and fixing of the optical drive module 2. When disassembling the optical drive module 2, loosen the hand screw, remove the wiring at the rear of the optical drive 21, keep the hand screw away from the spring clip buckle 31, restore the spring clip buckle 31 to its original state, and make the straight portion 313 exit the limit groove 16, and then the optical drive module 2 can be taken out.

When both ends of the stop shaft 33 move to the first fixed position 171, the optical drive module 2 is locked in the positioning space; when both ends of the stop shaft 33 move to the second fixed position 172, the optical drive module 2 can be pulled out from the opening. When installing the optical drive module 2, when the stop shaft 33 is located at the second fixed position 172, the optical drive module 2 is inserted into the positioning space from the opening, and then the stop shaft 33 is moved along the slide groove 17 to the first fixed position 171, and the stop shaft 33 clamps the rear part of the optical drive 21, thereby locking the optical drive module 2 in the positioning space; when disassembling the optical drive module 2, the stop shaft 33 is slid along the slide groove 17 to the second fixed position 172, and then the optical drive module 2 can be pulled out from the opening.

[0059] Specifically, the slide groove 17 includes a transverse groove 173 and a first vertical groove 174 and a second vertical groove 175 extending downward from both ends of the transverse groove 173 respectively. The bottom of the first vertical groove 174 is a first fixed position 171, and the bottom of the second vertical groove 175 is a second fixed position 172. The first fixed position 171 is higher than the second fixed position 172. The first fixed position 171 is arranged between the upper surface and the lower surface of the optical drive 21, and the second fixed position 172 is arranged below the lower surface of the optical drive 21 and is located above the upper surface of the adjacent optical drive. This ensures that when the stop shaft 33 is located at the second fixed position 172, the optical drive module 2 can be taken out from the rear without affecting the installation and removal of the adjacent optical drive module 2.

[0060] Specifically, the locking mechanism 3 further includes a locking nut 34. Both ends of the stop shaft 33 are provided with threaded portions, the threaded portions are located in the slide groove 17, and the locking nut 34 is screwed on the threaded portions. When the stop shaft 33 is moved to the first fixed position 171, the locking nut 34 is tightened to fix the stop shaft 33 on the optical drive frame 1. After the locking nut 34 is loosened, the stop shaft 33 can slide along the slide groove 17 to the second fixed position 172, and the optical drive module 2 can be taken out.

[0061] In the above embodiment, the locking mechanism 3 is designed to be a stop shaft 33 and a locking nut 34, which completely avoids the contact between the locking mechanism 3 and the optical drive module 2. In other words, during the installation of the optical drive module 2, no external force is applied thereto, which can ensure the quality and installation accuracy of the optical drive to the greatest extent. There is no need to disassemble the locking mechanism 3 during the installation process, and the optical drive module 2 can be installed and locked by simply moving the stop shaft 33.

When installing the optical drive module 2, loosen the bolt 35, keep the bolt 35 away from the extension portion 231, insert the optical drive module 2 into the positioning space from the open position, and then pass the bolt 35 through the through hole and screw it into the connection hole, or pass the bolt 35 through the through hole and the connection hole in turn and lock it by the nut 36, so as to fix the optical drive module 2 in the positioning space.

[0063] See also Figures 18 to 20 In some embodiments, the optical drive side cover 23 includes an extension portion 231, which extends to the rear of the optical drive 21. The end of the extension portion 231 is provided with an outer flange 233. The locking mechanism 3 is used to fix the outer flange 233 on the optical drive frame 1, thereby achieving the fixation of the optical drive module 2 and the optical drive frame 1. In this fixing method, the locking mechanism 3 does not contact the optical drive 21 and will not affect the quality of the optical drive.
