Description

Technical Field

[0001] The invention relates to the technical field of optical disc storage, and in particular to a desktop optical disc access device. Background Art

[0002] Data storage refers to storing data on a certain medium for subsequent use. Common storage media include hard disks, USB flash drives, and optical disks. The lifespan of hard disk storage is generally 3 to 5 years. Compared with hard disk storage, optical disk storage can store data and the lifespan of optical disks can reach more than 50 years.

[0003] At present, the existing optical disk access devices are divided into two types according to different working modes: mechanical hand grabbing disk and circular disk array horizontal pushing mode. First, the mechanical hand grabbing disk method has a complex movement mechanism, which is easy to slip out of the movement mechanism during the process of grabbing the optical disk, commonly known as "disc drop", and has poor protection effect on the read and write area of ​​the optical disk. The optical disk is easy to wear to the read and write area during movement, thus causing data damage. Second, the vertically arranged circular disk array pushing mode is usually used to push the optical disk in the horizontal direction, which has complex structural requirements for the optical disk storage library, high cost, and many production and assembly steps, which is easy to cause cumulative errors; when the optical disk moves between the storage position and the working position, there is still a risk of causing wear to the optical disk read and write area.

[0004] In summary, the existing optical disc access device has a complex motion mechanism, which is prone to disc dropping. The optical disc storage library has a complex structure and poor assembly accuracy, which can easily lead to wear and damage of the read and write area of ​​the optical disc and data loss.

[0022] Compared with the prior art, the desktop optical disc access device of the present invention has the following beneficial effects: the desktop optical disc access device adopts a design form of a main shell, an upper cover, an optical disc storage structure, a rotating drive, a first ejection mechanism and a second ejection mechanism, the upper cover is installed on the upper side of the main shell, and the upper cover is provided with a slot communicated with the internal space of the main shell, and the optical disc can be inserted into the main shell through the slot, or the optical disc can be taken out of the main shell through the slot.

[0040] An access port 33 is provided on the upper side of the storage slot 30 for inserting and removing the optical disc 31. Guide edges 32 are provided on both sides of the storage slot 30, and the guide edges 32 are used to position and cooperate with the edge non-read and write area 310 of the optical disc 31.

The main housing 1 is also provided with a suction optical drive 10 on the upper side of the optical disc storage structure 3, and the suction optical drive 10 corresponds to the second ejection mechanism 6 up and down.

[0041] A top entrance 34 is provided at the lower side of the disk storage slot 30, and a stopper 35 is provided on the inner side of the top entrance 34 for vertically stopping the optical disk 31. The first ejection mechanism 5 and the second ejection mechanism 6 are both equipped with a top plate 50, which is arranged on the lower side of the top entrance 34 for vertical movement and is used to lift and cooperate with the optical disk 31 in the disk storage slot 30.

[0042] The desktop optical disc access device adopts a design form of a main shell 1, an upper cover 2, an optical disc storage structure 3, a rotating drive 4, a first ejection mechanism 5 and a second ejection mechanism 6. The upper cover 2 is installed on the upper side of the main shell 1. The upper cover 2 is provided with a slot 20 communicated with the internal space of the main shell 1. The optical disc 31 can be inserted into the main shell 1 through the slot 20, or the optical disc 31 can be taken out of the main shell 1 through the slot 20.

[0043] The optical disk storage structure 3 is rotatably mounted in the main housing 1, and the rotation axis of the optical disk storage structure 3 is arranged to extend vertically. The rotary driver 4 is in transmission connection with the optical disk storage structure 3, and the optical disk storage structure 3 is provided with a plurality of storage slots 30 at intervals in the circumferential direction about the rotation axis. The optical disk storage structure 3 can accommodate a plurality of optical disks 31 to be inserted into the storage slots 30, and can meet the requirements of batch and high-density storage of optical disks 31. In addition, the optical disk storage structure 3 can rotate circumferentially around the rotation axis. When one of the storage slots 30 is aligned with the slot 20, the optical disk 31 can be stored in the storage slot 30 or taken out of the storage slot 30 through the access port 33 of the storage slot 30.

[0044] Among them, guide edges 32 are respectively provided on both sides of the disk storage slot 30, and the guide edges 32 are used to position and cooperate with the edge non-read-write area 310 of the optical disk 31. The guide edges 32 are located on both sides of the disk storage slot 30. In the process of storing and accessing the optical disk 31, the guide edges 32 are used to position and cooperate with the edge non-read-write area 310 of the optical disk 31, which not only ensures that the storage position of the optical disk 31 is reliable and avoids the disc from falling; and the guide edges 32 are limited to contact with the edge non-read-write area 310, thereby avoiding possible friction damage to the read-write area 311 of the optical disk 31 caused by the inner wall of the disk storage slot 30, thereby ensuring that the optical disk 31 is well protected during the storage and access movement.

[0045] In addition, the first ejection mechanism 5 and the second ejection mechanism 6 are respectively arranged at the lower side of the optical disk storage structure 3, and the slot 20 corresponds to the first ejection mechanism 5 up and down, and the slot-in optical drive 10 corresponds to the second ejection mechanism 6 up and down. The first ejection mechanism 5 is arranged corresponding to the slot 20, and can eject the optical disk 31 in the storage slot 30 to the upper side of the slot 20, so that the user can take out the optical disk 31; the second ejection mechanism 6 is arranged corresponding to the slot-in optical drive 10, and can eject the optical disk 31 in the storage slot 30 to the slot-in optical drive 10, and the slot-in optical drive 10 can automatically suck in the optical disk 31 and read the data in the optical disk 31.

[0046] It should be noted that a top inlet 34 is provided at the lower side of the storage slot 30, and a stopper 35 for vertically stopping the optical disc 31 is provided inside the top inlet 34. A top plate 50 is installed on the upper part of the first ejection mechanism 5 and the second ejection mechanism 6, and the top plate 50 is arranged at the lower side of the top inlet 34 for vertical movement. When the ejection mechanism is in the reset state, its top plate 50 is located at the lower side of the optical disc 31, and the optical disc 31 is kept in the storage position under the limitation of the stopper 35. Moreover, at this time, the top plate 50 of the ejection mechanism will not interfere with the optical disc 31, thereby ensuring the reliability of the rotation action of the optical disc storage structure 3.

[0047] When the ejection mechanism is in the ejection state, the top plate 50 plays an upward pushing role on the optical disc 31, so that the optical disc 31 can be moved to the upper side of the access port 33, so that the optical disc 31 can be taken out from the slot 20 and the optical disc 31 can be sucked into the slot-type optical drive 10. The desktop optical disc access device is designed with a rotation and direct motion mechanism, and the optical disc 31 is accurately limited in the storage slot 30 to avoid the possibility of the disc falling. The optical disc storage structure 3 has a simple structure and low requirements for assembly accuracy, which effectively prevents the problems of wear and damage of the read-write area 311 of the optical disc 31 and data loss.

[0048] In this embodiment, the optical disk storage structure 3 is a circular disk structure, and a plurality of storage slots 30 are arranged along the radial direction of the optical disk storage structure 3, and the thickness of the optical disk storage structure 3 is less than the diameter of the optical disk 31. The optical disk storage structure 3 is made of integrated injection molding, which can simplify the assembly process of production and reduce the cumulative error of assembly. When the optical disk 31 is placed in the storage slot 30, the lower half of the optical disk 31 can be suspended from the top entrance 34, and the top plate 50 of the first ejection mechanism 5 and the top plate 50 of the second ejection mechanism 6 do not need to extend into the top entrance 34, and the optical disk 31 in the storage slot 30 can be lifted to the upper side of the access port 33.

[0049] As a further preferred solution, the guide edge 32 is protrudingly arranged on the inner wall of the disk storage slot 30, and a guide groove 320 is also provided on the inner side of the guide edge 32, and the guide groove 320 is used to fit with the edge non-read / write area 310 of the optical disk 31. The guide edge 32 is protrudingly arranged relative to the inner wall of the disk storage slot 30, and the guide groove 320 of the guide edge 32 can accurately guide the edge non-read / write area 310 of the optical disk 31, thereby preventing the inner wall of the disk storage slot 30 from causing wear and damage to the read / write area 311 of the optical disk 31.

[0050] Specifically, the width of the guide groove 320 in the length direction of the access port 33 is an arbitrary size of 0.5 mm to 3 mm. The width of the guide groove 320 is slightly larger than the width of the edge non-read / write area 310 of the optical disc 31. It can not only accommodate the edge non-read / write area 310 of the optical disc 31 for guiding and positioning, but also avoid wear and damage to the read / write area 311 of the optical disc 31 due to excessive width.

[0051] Moreover, the guide edge 32 includes a vertical section and an arc section. The vertical section is arranged on the upper inner side of the disk storage slot 30, and the distance between the vertical sections of the two guide edges 32 matches the diameter of the optical disk 31, ensuring that the vertical sections of the guide edges 32 on both sides can accurately guide the optical disk 31 into the disk storage slot 30. The arc section is smoothly connected to the lower side of the vertical section. The arc sections of the two guide edges 32 match the outer contour of the optical disk 31 in a concave-convex manner, and the arc sections of the two guide edges 32 constitute a stopper 35 for vertically stopping the optical disk 31. The arc sections of the guide edges 32 on both sides play a vertical stopping role on the optical disk 31, ensuring that the lower half of the optical disk 31 is exposed from the top inlet 34 and remains in a suspended state, effectively preventing the disk from falling.

[0052] In this embodiment, the rotation driver 4 includes a bottom bracket 40, a driving motor 41, a rotating spindle 42 and a fixing frame 43. The bottom bracket 40 is fixedly connected to the inner side of the bottom plate of the main shell 1, the driving motor 41 is installed on the bottom bracket 40, the rotating spindle 42 is rotatably installed on the bottom bracket 40, the driving motor 41 is transmission-connected to the rotating spindle 42, and the fixing frame 43 is rotationally connected to the upper end of the rotating spindle 42 and is fixedly connected to the optical disc storage structure 3.

[0053] Specifically, the motor shaft of the driving motor 41 is fixedly connected with a driving gear 44, the rotating main shaft 42 is fixedly connected with a driven gear 45, a synchronous belt 46 is connected between the driving gear 44 and the driven gear 45, and a bearing 47 is also provided between the rotating main shaft 42 and the bottom bracket 40. A gear-belt transmission design is adopted, and the driving motor 41 drives the driving gear 44, the synchronous belt 46 and the driven gear 45 to operate, thereby driving the rotating main shaft 42, the fixing frame 43 and the optical disk storage structure 3 to rotate, so as to achieve the purpose of accurately controlling the rotation of the optical disk storage structure 3.

[0054] The first ejection mechanism 5 is the same as the second ejection mechanism 6, and includes a base 51 and an electric push rod 52. The base 51 is fixedly connected to the inner side of the bottom plate of the main housing 1, and the electric push rod 52 is installed on the base 51. The top plate 50 is fixedly connected to the upper part of the electric push rod 52, and the upper side of the top plate 50 is provided with an arc edge that matches the outer contour of the optical disc 31. The electric push rod 52 can drive the top plate 50 to move up and down, and the arc edge of the top plate 50 can form an accurate lifting and supporting effect with the optical disc 31.

[0055] It should be noted that the first ejection mechanism 5 is the same as the second ejection mechanism 6. The first ejection mechanism 5 has a reset state and an ejection state. In the reset state, the top plate 50 is arranged at intervals on the lower side of the optical disc 31, avoiding the first ejection mechanism 5 and the second ejection mechanism 6 from interfering with the optical disc 31, ensuring that the optical disc storage structure 3 can rotate smoothly. In the ejection state, the top plate 50 is close to the ejection entrance 34, and the up and down stroke of the top plate 50 is any size from one quarter to one half of the diameter of the optical disc 31, ensuring that the top plate 50 can effectively eject the optical disc 31 in the storage slot 30 to the upper side of the access port 33.

[0056] In addition, the upper cover 2 is hingedly mounted on the upper side of the main shell 1. The upper cover 2 is a step-shaped upper cover, which includes a first step surface 21 and a second step surface 22 that are staggered up and down. The slot 20 is opened in the middle of the first step surface 21, and the suction optical drive 10 is arranged on the lower side of the second step surface 22 when the upper cover 2 is closed. The slot 20 is opened on the first step surface 21 of the upper cover 2, and the optical disc 31 in the optical disc storage structure 3 can be smoothly ejected to the upper side of the slot 20 through the first ejection mechanism 5, so that the user can take out the optical disc 31. The suction optical drive 10 is arranged on the lower side of the second step surface 22 when the upper cover 2 is closed, which can fully accommodate the suction optical drive 10 and avoid mutual interference with the optical disc storage structure 3.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
