Description

Technical Field

[0001] This application relates to the technical field of optical disc storage, and more particularly to an optical disc storage device. Background Technology

[0002] With the increasing awareness of information security, optical discs, as a physically isolated data storage medium, have demonstrated unique advantages in areas such as classified information management and important data archiving. Optical disc data storage systems, due to their tamper-proof nature, resistance to electromagnetic interference, and strong long-term storage stability, have gradually become a highly secure inter-network information exchange system, widely used in industries with high data security requirements, such as government, finance, and military. Among various optical disc storage structures, rotary disc storage systems occupy an important position in the market due to their efficient read / write path control, good space utilization, and modular, scalable structural design. This system uses a rotating mechanism to achieve rapid positioning and retrieval of the target optical disc, improving overall operational efficiency and system reliability.

[0003] Currently common rotary optical disc storage systems feature stacked trays, each hinged to the rotary drum body. These trays can be folded inside the drum to save space or partially extended outside for easy insertion and removal of discs. To ensure tray stability when not in use and controllability during operation, existing technologies typically employ positioning rods as limiting and returning mechanisms. When a tray is pulled out, the positioning rods, acting as limiters during drum rotation, return the extended tray to its predetermined position, thus achieving automatic return. This method improves the ease of operation and structural stability of the equipment to some extent.

[0004] Although existing rotary optical disc storage systems are relatively mature in terms of structural design and operational logic, they still have significant shortcomings. In particular, during the tray return process, the tray's trajectory needs to contact the positioning rod, resulting in relative sliding. Prolonged friction causes wear and tear on the tray surface material, leading to dust accumulation and contamination of the storage environment, affecting the cleanliness and read / write stability of the optical discs. Furthermore, dust accumulation can cause mechanical component jamming and control system misjudgments, reducing the overall lifespan and operational reliability of the equipment. Therefore, there is an urgent need to improve the existing tray return structure to reduce or avoid sliding friction between the tray and the positioning rod, thereby enhancing the cleanliness and durability of the storage system to meet the practical needs of high-security and high-stability applications. Utility Model Content

[0005] This application provides an optical disc storage device to solve the technical problem of tray powder shedding caused by friction between the tray and positioning components in current optical disc storage devices, thereby avoiding a poor optical disc storage environment. The technical solution is as follows:

[0006] This application provides an optical disc storage device, including: a rotating drum body that can rotate about its own axis; a plurality of trays stacked in the rotating drum body for storing optical discs; each tray is hinged to the rotating drum body, and the flipping direction of the tray is perpendicular to the axis of the rotating drum, so that the tray has a first working position that is received inside the rotating drum body and a second working position that partially extends out of the rotating drum body; and a positioning member that extends along the stacking direction of each tray, is disposed on one side of the rotating drum body, and the positioning member can rotate about its own axis.

[0007] When the rotating cage body drives the pallet to rotate synchronously, the pallet in the second station abuts against the positioning component. The positioning component is driven to rotate by the reverse force of the pallet, and the positioning component drives the pallet in the second station to flip to the first station.

[0008] In one embodiment, the positioning component includes: a first mounting base; a first bearing disposed on the first mounting base; and a rotating rod connected to the first mounting base via the first bearing, the radial side of the rotating rod being used to contact the tray.

[0009] In one embodiment, a first mounting base is provided with a first connecting hole; a first bearing is installed in the first connecting hole; a rotating rod has a first connecting end, which passes through the first connecting hole and is inserted into the first bearing.

[0010] In one embodiment, the positioning component further includes: a first limiting member, which is embedded in the first connecting hole and located on the side of the first bearing near the opening of the first connecting hole, for fixing the first bearing.

[0011] In one embodiment, it further includes: a first mounting plate, on which the rotating cage body is rotatably disposed, and the end of the first mounting seat opposite to the first bearing is connected to the first mounting plate.

[0012] In one embodiment, it further includes: a second mounting plate disposed on the side of the rotating drum body opposite to the first mounting plate, and the rotating drum body is rotatably mounted on the second mounting plate.

[0013] The positioning component also includes: a second mounting base connected to a second mounting plate; a second bearing disposed at one end of the second mounting base opposite to the second mounting plate; and a rotating rod connected to the second mounting base via the second bearing.

[0014] In one embodiment, the second mounting base has a second connecting hole on the side opposite to the second mounting plate; the second bearing is installed in the second connecting hole; the rotating rod has a second connecting end, which passes through the second connecting hole into the second bearing.

[0015] In one embodiment, the positioning component further includes a second limiting member, which is embedded in the second connecting hole and located on the side of the second bearing near the opening of the second connecting hole, for fixing the second bearing.

[0016] Compared to existing technologies, the optical disc storage device proposed in the above technical solution improves the traditional fixed positioning component into a rotating one, and cleverly utilizes the reverse force applied during tray movement to drive its rotation. This effectively reduces the sliding friction between the tray and the positioning component, thereby avoiding dust generation from tray surface wear and significantly improving the cleanliness and stability during optical disc storage. In use, when the tray in the second station rotates with the drum and contacts the positioning component, the tray applies a tangential force to the positioning component, driving its rotation. This rotation process transforms the original sliding friction into rolling or low-resistance contact, greatly reducing the friction intensity between the tray and the positioning component. This fundamentally avoids material wear and dust shedding caused by friction during long-term use, improving the equipment's lifespan and operational reliability. Since tray dust shedding is one of the main sources of dust accumulation in the optical disc storage environment, and the presence of dust can affect the read / write performance of the optical disc and even cause data corruption. This application significantly reduces dust generation by lowering the coefficient of friction between the tray and the positioning components, thereby maintaining the cleanliness of the optical disc storage space. This helps improve the stability of optical disc access and the accuracy of data reading and writing, and is especially suitable for applications with extremely high data security requirements, such as government, finance, and military industries.

[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0034] Reference Figure 1 As shown, an embodiment of this application proposes an optical disc storage device, which may include: a rotating drum body 1, which is rotatable about its own axis; a plurality of trays 2, which are stacked in the rotating drum body 1 for storing optical discs; each tray 2 is hinged to the rotating drum body 1, and the flipping direction of the tray 2 is perpendicular to the axis of the rotating drum, so that the tray 2 has a first station that is received inside the rotating drum body 1 and a second station that partially extends out of the rotating drum body 1; and a positioning member 3, which extends along the stacking direction of each tray 2, is disposed on one side of the rotating drum body 1, and the positioning member 3 is rotatable about its own axis.

[0035] When the rotating cage body 1 drives the pallet 2 to rotate synchronously, the pallet 2 in the second station abuts against the positioning component 3. The positioning component 3 is driven to rotate by the reverse force of the pallet 2, and the positioning component 3 drives the pallet 2 in the second station to flip to the first station.

[0036] Specifically, in the technical solution adopted in this application, several stacked trays 2 are arranged on the rotating drum body 1 to enable independent storage of optical discs by each tray 2. The trays 2 can be connected to the rotating drum body 1 by hinge shafts, and each tray 2 moves around the corresponding hinge shaft as the rotation center, so that each tray 2 can move in a flipping manner to the inside and outside of the rotating drum body 1 to form a first work station and a second work station. The tray 2 in the first work station is located inside the rotating drum body 1 and is used to store optical discs in the rotating drum body 1, while the tray 2 in the second work station can facilitate the placement or removal of optical discs in the tray 2; in one embodiment, the rotating drum body 1 can rotate around its own axis. When the positioning component 3 is engaged with the rotating drum body 1, the positioning component 3 can drive the tray 2 in the second station to return to the first station by flipping it. The key technical point of this application is that the positioning component 3 is configured to have a structure that can rotate around its own axis. Thus, during the process of the positioning component 3 driving the tray 2 back to the first station, the positioning component 3 is subjected to the reverse force of the tray 2. Based on the friction generated between the tray 2 and the positioning component 3, the positioning component 3 is driven to rotate, so as to avoid the phenomenon of powder falling off the tray 2 due to friction when it contacts the positioning component 3. This effectively improves the storage environment of the optical disc in the tray 2 and avoids unnecessary damage to the optical disc due to dust.

[0037] Furthermore, refer to Figures 2 to 4 As shown, in some embodiments, the positioning component 3 includes: a first mounting base 31; a first bearing 32 disposed on the first mounting base 31; and a rotating rod 37 connected to the first mounting base 31 via the first bearing 32, the radial side of the rotating rod 37 being used to contact the tray 2.

[0038] Specifically, in the technical solution adopted in this application, in order to realize the rotation function of the positioning component 3 around its axial direction, in one embodiment, the positioning component 3 may include: a first mounting base 31 fixedly installed on the target site or target equipment and a rotating rod 37 for contacting the tray 2. A first bearing 32 is disposed on the first mounting base 31, and the rotating rod 37 is mounted on the first mounting base 31 through the first bearing 32, so that the rotating rod 37 can rotate based on the first mounting base 31 after contacting the tray 2. Specifically, the radial side of the rotating rod 37 contacts the tray 2, and in use, the rotating rod 37 can be driven to rotate by the friction force generated between the tray 2 and the rotating rod 37.

[0039] Furthermore, refer to Figure 4 As shown, in some embodiments, the first mounting base 31 is provided with a first connecting hole 311; the first bearing 32 is installed in the first connecting hole 311; the rotating rod 37 has a first connecting end 371, which passes through the first connecting hole 311 into the first bearing 32.

[0040] Specifically, in the technical solution adopted in this application, in order to enable the rotating rod 37 to be mounted on the first mounting base 31 via the first bearing 32, a first connecting hole 311 can be opened on the first mounting base 31. During installation, the first bearing 32 can be installed in the first connecting hole 311, and one end of the rotating rod 37 has a first connecting end 371, so that the first connecting end 371 is inserted into the first connecting hole 311 and together with it is inserted into the first bearing 32, thereby enabling the rotating rod 37 to rotate based on the first mounting base 31 via the first bearing 32.

[0041] Furthermore, refer to Figure 4 As shown, in some embodiments, the positioning component 3 further includes: a first limiting member 33, which is embedded in the first connecting hole 311 and located on the side of the first bearing 32 near the opening of the first connecting hole 311, for fixing the first bearing 32.

[0042] Specifically, in the technical solution adopted in this application, the first limiting member 33 can be a C-shaped retaining ring, which is embedded in the first connecting hole 311 and fits against the side of the first bearing 32 near the opening of the first connecting hole 311. Thus, by configuring the first limiting member 33 in the first connecting hole 311, the first bearing 32 can be prevented from dislodging from the first connecting hole 311, thereby strengthening the connection between the first bearing 32 and the first mounting base 31.

[0043] Furthermore, refer to Figure 1 As shown, in some embodiments, it further includes: a first mounting plate 4, the rotating cage body 1 is rotatably disposed on the first mounting plate 4, and the end of the first mounting base 31 opposite to the first bearing 32 is connected to the first mounting plate 4.

[0044] Specifically, in the technical solution adopted in this application, the rotating cage body 1 and the positioning component 3 can be configured on the first mounting plate 4. In one embodiment, the first mounting plate 4 can be the bottom that can contact the ground, and the rotating cage body 1 can rotate based on the first mounting plate 4 and along its own axis. When the first end of the first mounting seat 31 away from the first bearing 32 is fixedly connected to the first mounting plate 4, the rotating rod 37 can rotate based on the first mounting seat 31 through the first bearing 32.

[0045] Furthermore, refer to Figure 3 , Figure 5 as well as Figure 6As shown, in some embodiments, it further includes: a second mounting plate 5, disposed on the side of the rotating cage body 1 away from the first mounting plate 4, and the rotating cage body 1 is rotatably disposed on the second mounting plate 5; the positioning component 3 further includes: a second mounting base 34, connected to the second mounting plate 5; a second bearing 35, disposed at the end of the second mounting base 34 away from the second mounting plate 5; and a rotating rod 37 connected to the second mounting base 34 through the second bearing 35.

[0046] Specifically, in one embodiment of the technical solution adopted in this application, the rotating cage body 1 and the positioning component 3 can be configured on a first mounting plate 4 and a second mounting plate 5. The first mounting plate 4 can be a bottom plate that can contact the ground, while the second mounting plate 5 can be a top plate with the mounting base located on top of the rotating cage body 1. The rotating cage body 1 can rotate along its own axial direction based on the first mounting plate 4 and the second mounting plate 5. The positioning component 3 can also include a second mounting base 34 connected to the second mounting plate 5 and a second bearing 35 configured on the second mounting base 34. The end of the rotating rod 37 facing away from the first mounting base 31 is connected to the second mounting base 34 through the second bearing 35, so that the rotating rod 37 rotates based on the first mounting base 31 and the second mounting base 34 through the first bearing 32 and the second bearing 35. Compared with the above embodiment where the rotating rod 37 rotates based on the first mounting base 31, since the two ends of the rotating rod 37 in this embodiment are limited in the corresponding first mounting base 31 and second mounting base 34, the displacement of the rotating rod 37 during rotation can be better avoided, making the rotation of the rotating rod 37 more stable and reliable.

[0047] Furthermore, refer to Figure 5 As shown, in some embodiments, the second mounting base 34 is provided with a second connecting hole 341 on the side opposite to the second mounting plate 5; the second bearing 35 is installed in the second connecting hole 341; the rotating rod 37 has a second connecting end 372, which passes through the second connecting hole 341 and is inserted into the second bearing 35.

[0048] Specifically, in the technical solution adopted in this application, in order to enable the rotating rod 37 to be mounted on the second mounting base 34 via the second bearing 35, a second connecting hole 341 can be opened on the second mounting base 34. During installation, the second bearing 35 can be installed in the second connecting hole 341, and the end of the rotating rod 37 facing away from the first mounting base 31 has a second connecting end, so that the second connecting end 372 can be inserted into the second connecting hole 341 and together with it through the second bearing 35, thereby enabling the rotating rod 37 to rotate based on the second mounting base 34 via the second bearing 35.

[0049] Furthermore, refer to Figure 5As shown, in some embodiments, the positioning component 3 further includes a second limiting member 36, which is embedded in the second connecting hole 341 and located on the side of the second bearing 35 near the opening of the second connecting hole 341, for fixing the second bearing 35.

[0050] Specifically, in the technical solution adopted in this application, the second limiting member 36 can be a C-shaped retaining ring, which is embedded in the second connecting hole 341 and fits against the side of the second bearing 35 near the opening of the second connecting hole 341. Thus, by configuring the second limiting member 36 in the second connecting hole 341, the second bearing 35 can be prevented from dislodging from the second connecting hole 341, thereby strengthening the connection between the second bearing 35 and the second mounting base 34.
