DETAILED DESCRIPTION

[0038] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0039] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show the structures related to the present application rather than being drawn according to the number, shape and size of the structures in actual implementation. In actual implementation, the type, quantity and proportion of each structure may be changed arbitrarily, and its structural layout may also be more complicated.

[0040] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.

[0041] Figure 1 A schematic perspective view of an optical disc cartridge according to an embodiment of the present invention is shown. Figure 2 A schematic cross-sectional view of a partial structure of an optical disc cartridge according to an embodiment of the present invention is shown, in which the limiting member and the trigger mechanism do not generate any force. Figure 3 Shows Figure 2 A is a schematic enlarged view shown. Figure 4 Shows Figure 2 The schematic enlarged diagram of B is shown. Figures 1 to 4 As shown, the optical disc cartridge comprises an outer shell 1, an inner cartridge 2 disposed in the outer shell 1 and capable of being removed from the outer shell 1, and at least two sets of position limiting components. The inner cartridge 2 has an optical disc accommodating portion 21 for accommodating a plurality of stacked optical discs 4.

[0042] Each set of limiting components includes a trigger mechanism 31 and a limiting member 32. The trigger mechanism 31 is disposed in the housing 1. The limiting member 32 is disposed on the outer periphery of the optical disc accommodating portion 21, and moves with the inner case 2 when the inner case 2 is moved into the housing 1 until a force is generated with the trigger mechanism 31, thereby moving to a position that contacts or approaches the outer edges of the multiple optical discs 4 under the triggering action of the trigger mechanism 31. The limiting members 32 of the at least two sets of limiting components limit the multiple optical discs 4 together, thereby preventing displacement between the multiple optical discs 4.

[0043] According to the solution of the present invention, by setting at least two sets of limiting components, a trigger mechanism 31 is set in the outer shell 1, and a limiting member 32 is set on the outer periphery of the optical disc accommodating portion 21. The limiting member 32 can generate a force with the trigger mechanism 31 when the inner case 2 is moved into the outer shell 1, so that it can resist or approach the outer edges of the multiple optical discs 4, and then limit the multiple optical discs 4, so as to prevent the multiple optical discs 4 from being displaced. Therefore, when the optical discs 4 are placed in the optical disc case for transportation, due to the limiting of at least two sets of limiting components, it can be prevented that the multiple optical discs 4 are displaced and the friction of the disc surface is damaged.

[0044] Figure 5 A schematic structural diagram of a position-limiting member 32 according to an embodiment of the present invention is shown. Figure 6 Another schematic cross-sectional view of a partial structure of an optical disc cartridge according to an embodiment of the present invention is shown, in which a limiting member 32 and a trigger mechanism 31 generate a force. Figure 7 Shows Figure 6 A schematic enlarged view of point C is shown. Figure 8 Shows Figure 6 The schematic enlarged view of D is shown. Figures 1 to 8, the trigger mechanism 31 has a trigger portion 311, the limiting member 32 includes a limiting portion 321, and the limiting member 32 is configured to rotate when the limiting member 32 generates a force with the trigger mechanism 31, so that the limiting portion 321 abuts against or approaches the outer edges of the multiple optical disks 4. In other words, as long as the limiting member 32 has the limiting portion 321, and the limiting portion 321 can abut against or approach the outer edges of the multiple optical disks 4 when the limiting member 32 rotates, the multiple optical disks 4 can be limited by the joint action of the multiple limiting members 32. It can be understood that the multiple limiting members 32 are also arranged around the outer circumference of the optical disk 4, so that the multiple optical disks 4 can be limited by the joint action of the multiple limiting members 32.

[0045] The limiting part 321 has a contact surface 3211 and a push surface 3212. The contact surface 3211 faces the outer edge of the optical disc 4 so as to approach or contact the outer edge of the optical disc 4 when limiting the optical disc 4. There is an angle between the push surface 3212 and the contact surface 3211. The push surface 3212 faces the triggering part 311 so as to be able to contact the triggering part 311, and the limiting member 32 rotates under the action of the triggering part 311 until the contact surface 3211 of the limiting part 321 contacts or approaches the outer edges of the multiple optical discs 4. When the inner case 2 is moved out of the outer shell 1, the triggering part 311 is separated from the limiting part 321 so as not to interact with each other. At this time, the push surface 3212 is also separated from the triggering part 311, and the limiting member 32 returns to the initial state, that is, the limiting member 32 rotates to the position where the contact surface 3211 does not approach or contact the outer edge of the optical disc 4, so that the multiple limiting members 32 cannot limit the multiple optical discs 4. The force for the limiting member 32 to return to the initial state may be provided by a torsion spring, for example, or by other means, so that the limiting member 32 can automatically return to the initial state when the inner box 2 is moved out of the outer shell 1 .

[0046] See also Figure 5 The limiting part 321 includes a first part 3213 and a second part 3214 connected to the first part 3213, and the same side of the first part 3213 and the second part 3214 together form a contact surface 3211. The height of the first part 3213 is higher than that of the second part 3214, and the second part 3214 has a pushing surface 3212. The second part 3214 has a limiting hole 3215, and the limiting hole 3215 cooperates with the limiting shaft 22 set on the inner box 2 to limit the rotation stroke of the limiting member 32. The limiting hole 3215 can be, for example, a waist-shaped hole, and the limiting shaft 22 can be, for example, a pin. The first part 3213 has a connecting part 3216, and the lower end of the connecting part 3216 is connected to a torsion spring to drive the limiting member 32 to return to the initial state after the trigger mechanism 31 is separated from the limiting member 32.

[0047] The stopper 32 further includes a pivoting portion 3217, which is connected to the second portion 3214, and the pivoting portion 3217 and the first portion 3213 are respectively located on both sides of the second portion 3214. The height of the pivoting portion 3217 is lower than the height of the second portion 3214. The outer contours of the pivoting portion 3217, the first portion 3213 and the second portion 3214 are generally triangular. The stopper 32 further includes an abutting portion 3218, which is configured to abut against the stopper seat 312 in the outer shell 1 when the inner box 2 moves to a preset position in the outer shell 1. The abutting portion 3218 is, for example, located at a corner of the triangle of the stopper 32 that is away from the optical disk 4.

[0048] At least two groups of limiting components include at least one inner limiting component located inside when the inner box 2 is moved into the outer shell 1, the outer shell 1 has an inner wall, the inner wall has an inner end 24 close to the inner side of the inner box 2 when the inner box 2 is moved into the outer shell 1, and the trigger mechanism 31 of the inner limiting component includes a limiting seat 312 and a push rod 313. The limiting seat 312 is arranged at the inner end 24 of the outer shell 1. The push rod 313 is connected to the limiting seat 312 and extends toward the space where the inner box 2 is located, and the end of the push rod 313 has the aforementioned triggering portion 311.

[0049] At least two groups of limiting components also include at least one outer limiting component located on the outer side when the inner box 2 is moved into the outer shell 1, and the inner wall also includes a side wall body and an outer end portion 23 close to the outer side of the inner box 2 when the inner box 2 is moved into the outer shell 1, and the outer end portion 23 and the inner end portion 24 are respectively located at the two ends of the side wall body. The trigger mechanism 31 of the outer limiting component is the outer end portion 23, and the outer end portion 23 has a taper so that the diameter of the outer end portion 23 is smaller than the diameter of the side wall body, so that when the limiting member 32 of the outer limiting component moves along the outer end portion 23 to the side wall body, the limiting member 32 contacts or approaches the outer edge of the optical disc 4. In this way, the inner box 2 can be smoothly moved into the outer shell 1, and the optical disc 4 can be smoothly locked, that is, the limiting member 32 contacts or approaches the outer edge of the optical disc 4 smoothly.

[0050] Fig. 9 FIG. 2 shows a schematic structural diagram of a stopper 32 according to another embodiment of the present invention. Fig. 9 As shown, a protrusion 322 extending in the vertical direction is also provided on one side of the abutting surface 3211 of the stopper 32. The uppermost end of the protrusion 322 protrudes in the direction of the optical disc 4, and the protrusion 322 can limit the upward movement of the optical disc 4 when the at least two groups of stopper components abut against or contact the outer edges of the multiple optical discs 4. The uppermost end of the protrusion 322 has an edge protruding toward the optical disc 4, so that the optical disc 4 can be limited to move upward. Therefore, when transporting the optical disc box storing the optical disc 4, the upward movement of the optical disc 4 can be limited by the protrusion 322 on the stopper 32.

[0051] The at least two groups of limiting components are arranged so that at least some of the limiting members 32 are away from the outer edges of the multiple optical discs 4 when the inner box 2 is moved out of the outer shell 1, thereby allowing displacement between the multiple optical discs 4. It is understandable that at least the limiting members 32 on the outer side of the inner box 2 need not limit the outer edges of the multiple optical discs 4 when the inner box 2 is moved out of the outer shell 1. The limiting members 32 on the inner side of the inner box 2 can limit or not limit the outer edges of the multiple optical discs 4 when the inner box 2 is moved out of the outer shell 1. In this way, the limiting members 32 can be separated from the limiting of the optical discs 4 when the inner box 2 needs to be moved out of the outer shell 1, so that the optical discs 4 can be taken out.

[0052] In one embodiment, the inner box 2 is provided with a plurality of sliding beads on the upper surface of the optical disc accommodating portion 21, and a plurality of anti-wear pads are provided on the inner wall of the upper cover of the outer shell 1 to prevent the data surface of the top optical disc 4 from contacting the outer shell 1 when the inner box 2 is moved into or out of the outer shell 1.

[0053] In particular, the present invention also provides an optical disc library having the above optical disc cartridge. In addition to the above optical disc cartridge, the optical disc library also includes a disc grabber, which can be a disc grabber in the prior art and will not be described in detail here.

[0054] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the general principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
