[0048] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] This embodiment provides a disc ejection device, which can be used in a disc storage device to eject a target disc from a plurality of densely arranged discs so that a user can take it out and use it. The disc ejection device is not only compact in structure and highly automated, but can also effectively improve the efficiency of disc taking, reduce the time required for disc taking, and improve the user experience, and can be matched to different disc storage devices, and has a wide range of applications.

[0052] like Figures 1 to 11As shown, the optical disc ejection device includes a driving mechanism, a slide plate 4 and a lever 5. Among them, the driving mechanism is the power component of the entire device, which specifically includes a power assembly 1, an eccentric member 2 and a connecting plate 3. The power assembly 1 is connected to the eccentric member 2 in a transmission manner, and is used to drive the eccentric member 2 to rotate around the first axis. An eccentric structure is provided on the eccentric member 2, and a sliding structure is provided in the middle of the connecting plate 3. The sliding structure cooperates with the eccentric structure so that the first end of the connecting plate 3 can rotate around the second axis under the drive of the power assembly 1. In this embodiment, the first axis and the second axis are both arranged vertically. The second end of the connecting plate 3 is rotatably connected to the slide plate 4, and when the first end of the connecting plate 3 rotates forward around the second axis, the slide plate 4 can move linearly along the first direction a, and when the first end of the connecting plate 3 rotates reversely around the second axis, the slide plate 4 can move linearly along the second direction b. In this embodiment, the first direction a and the second direction b are arranged oppositely. One end of the lever 5 is a contact end, and the other end is a moving end. The middle part of the lever 5 is rotatably arranged around the third axis. The contact end of the lever 5 contacts the slide plate 4. When the slide plate 4 moves linearly along the first direction a, the moving end of the lever 5 is raised to eject the optical disc, and when the slide plate 4 moves linearly along the second direction b, the moving end of the lever 5 is pressed downward. In this embodiment, the third axis is arranged horizontally.

[0053] The optical disc ejection device, driven by the power assembly 1, can finally realize the lifting or pressing down of the toggle end of the lever 5 through the sequential transmission of the eccentric piece 2, the connecting plate 3 and the sliding plate 4. When the toggle end of the lever 5 is lifted, the target optical disc can be automatically ejected. When the toggle end of the lever 5 is pressed down, it can be automatically reset to prepare for the next ejection of the target optical disc. Compared with the existing manual method of manually taking the target optical disc from the densely arranged optical discs in the optical disc storage device, the optical disc ejection device has a higher degree of automation, which can effectively improve the efficiency of optical disc taking, reduce the time required for optical disc taking, and improve the user experience.

[0054] Alternatively, if Figure 1As shown, the power assembly 1 includes a motor 101, a transmission wheel mechanism and a gear set mechanism. The motor 101 is arranged on the bottom plate 10 of the optical disc ejection device, and the motor shaft of the motor 101 is arranged vertically upward. The transmission wheel mechanism includes a driving wheel 102, a driven wheel 103 and a transmission belt 104. The driving wheel 102 is sleeved on the motor shaft of the motor 101, and the driven wheel 103 is spaced apart from the driving wheel 102. The transmission belt 104 is sleeved between the driving wheel 102 and the driven wheel 103 to achieve the transmission of power between the driving wheel 102 and the driven wheel 103. The gear set mechanism includes an input gear 105, an intermediate gear and an output gear 106 that are meshed in sequence. In this embodiment, the input gear 105 is coaxially arranged with the driven wheel 103. When the driven wheel 103 rotates, the input gear 105 rotates synchronously. The number of intermediate gears can be set to multiple according to needs, and multiple intermediate gears are meshed in sequence to achieve power transmission. The output gear 106 meshes with the gear teeth structure provided on the outer circumferential surface of the eccentric member 2, so as to realize the rotation of the eccentric member 2 around the first axis. Optionally, the intermediate gear and the output gear 106 can be coaxially arranged to improve the compactness of the structure.

[0055] Of course, in other embodiments, the power assembly 1 may also include only the motor 101 and the transmission wheel mechanism, the driven wheel 103 of the transmission wheel mechanism is coaxially arranged with the eccentric member 2, and the driven wheel 103 is used to directly transmit power to the eccentric member 2, so that the eccentric member 2 rotates around the first axis; or only include the motor 101 and the gear set mechanism, the input gear 105 of the gear set mechanism is connected to the motor shaft of the motor 101, and the gear set mechanism is used to transmit power from the motor 101 to the eccentric member 2, so that the eccentric member 2 rotates around the first axis; or only include the motor 101, and the motor 101 is used to directly drive the eccentric member 2 to rotate around the first axis. In addition. The transmission wheel mechanism is not limited to a pulley mechanism, but can also be a sprocket mechanism. The gear set mechanism is not limited to a spur gear set, but can also be a bevel gear set, etc.

[0056] like Figure 7 and Figure 8 As shown, the eccentric member 2 is in the shape of a disk as a whole, and a first shaft hole is provided on it. The first shaft passes through the first shaft hole and is rotatably fixed on the bottom plate 10, and the central axis of the first shaft is the first axis. The eccentric structure is arranged on the lower surface of the eccentric member 2. In this embodiment, the eccentric structure is an eccentric groove 201, and the eccentric groove 201 is specifically an arc groove, which is arranged around the first axis. The eccentric groove 201 has at least two points with different distances from the first axis. Optionally, from one end of the eccentric groove 201 to the other end of the eccentric groove 201, the distance from each point in the eccentric groove 201 to the first axis gradually increases. Correspondingly, in this embodiment, the sliding structure used in conjunction with the eccentric structure on the connecting plate 3 is a sliding shaft 301, one end of which is fixedly connected to the middle part of the connecting plate 3, and the other end is placed in the eccentric groove 201.

[0057] The connecting plate 3 is placed on the bottom plate 10 and is located below the eccentric member 2. Fig. 9 As shown, in this embodiment, the connecting plate 3 is a triangular plate-like structure, and the sliding shaft 301 is convexly arranged in the middle of the upper surface of the connecting plate 3. In order to avoid the first rotating shaft, an avoidance groove 304 is also provided on the connecting plate 3, and the first rotating shaft passes through the avoidance groove 304 and is rotatably connected to the bottom plate 10. Optionally, the avoidance groove 304 is a U-shaped groove. A second rotating shaft hole 302 is provided on the first end of the connecting plate 3, and the second rotating shaft passes through the second rotating shaft hole 302 and is rotatably connected to the bottom plate 10, and a third rotating shaft hole 303 is provided on the other end, and a fourth rotating shaft hole 402 is provided on the slide plate 4, and the third rotating shaft passes through the third rotating shaft hole 303 and the fourth rotating shaft hole 402, thereby realizing the rotational connection between the connecting plate 3 and the slide plate 4. The central axis of the second rotating shaft is the second axis.

[0058] When the eccentric member 2 rotates around the first axis driven by the driving mechanism, the eccentric structure on the eccentric member 2 rotates accordingly. Since the sliding shaft 301 can only move in the eccentric groove 201, the side wall of the eccentric groove 201 can exert a force on the sliding shaft 301, thereby driving the connecting plate 3 to rotate around the second rotating axis, and then causing the second end of the connecting plate 3 to rotate.

[0059] like Fig.10 As shown, the slide plate 4 is a rectangular plate. In order to limit the moving track of the slide plate 4 so that the slide plate 4 can only move linearly along the first direction a or the second direction b under the drive of the connecting plate 3, the optical disc ejection device also includes a limiting mechanism, which is arranged on the side of the slide plate 4 and is used to make the slide plate 4 move linearly along the first direction a or the second direction b. Optionally, the limiting mechanism includes at least two limiting card plates 6, at least two limiting card plates 6 are arranged at intervals and form a limiting channel, and the slide plate 4 is arranged through the limiting channel. In this embodiment, four limiting card plates 6 are provided, and the four limiting card plates 6 are grouped in pairs, one group is arranged on both sides of the front end of the slide plate 4, and the other group is arranged on both sides of the rear end of the slide plate 4.

[0060] Optionally, the limiting card plate 6 is an L-shaped plate, the vertical plate of which is vertically fixed on the bottom plate 10, and the horizontal plate of which is arranged parallel to the bottom plate 10, and forms a space allowing the slide plate 4 to be accommodated and moved. Of course, in other embodiments, the limiting mechanism can also be a limiting groove arranged on the bottom plate 10, the slide plate 4 is placed in the limiting groove, and the moving direction of the slide plate 4 is limited by the limiting groove.

[0061] The lever 5 is arranged above the slide plate 4, and the two cooperate with each other to realize the lifting and pressing of the lever 5. Fig.10 As shown, a slope structure 401 is provided on the upper surface of the slide plate 4, and an inclined surface is provided on the slope structure 401. In this embodiment, along the first direction a, the height of the inclined surface gradually increases. Fig.11As shown, an abutment structure 501 is protruded below the abutment end of the lever 5, and the lower end of the abutment structure 501 always abuts against the inclined surface of the ramp structure 401. In this embodiment, the lower end surface of the abutment structure 501 is a horizontal plane, and there is a triangular gap between the horizontal plane and the inclined plane, which is conducive to the rotation of the lever 5 around the third axis.

[0062] When the slide plate 4 moves linearly along the first direction a, the ramp structure 401 moves synchronously along the first direction a, and the height of the portion of the ramp structure 401 below the abutment structure 501 gradually decreases, and the abutment structure 501 gradually decreases accordingly, so that the abutment end of the lever 5 gradually decreases. Since the middle part of the lever 5 is rotatably arranged around the third axis, the moving end of the lever 5 is gradually raised and ejects the target optical disc.

[0063] On the contrary, when the slide plate 4 moves linearly along the second direction b, the ramp structure 401 moves synchronously along the second direction b, and the height of the portion of the ramp structure 401 below the abutment structure 501 gradually increases, and the abutment structure 501 gradually increases accordingly, thereby causing the abutment end of the lever 5 to gradually increase. Since the middle part of the lever 5 is arranged to rotate around the third axis, the driving end of the lever 5 is gradually pressed downward, thereby achieving downward reset.

[0064] Specifically, Fig.11 As shown, the lever 5 includes a frame portion 502 and a lever portion connected in sequence, and the abutment structure 501 is a convex block convexly arranged below the frame portion 502. In this embodiment, there are two convex blocks, and the two convex blocks are arranged at intervals along the width direction of the frame portion 502. Correspondingly, two ramp structures 401 are provided, and abut against the two convex blocks one by one. The lever portion includes a first inclined plate 503 and a second inclined plate 504 connected to each other. One end of the first inclined plate 503 is connected to the frame portion 502, and the other end is connected to the second inclined plate 504. The bottom surface of the first inclined plate 503 is coplanar with the bottom surface of the second inclined plate 504, and the top surface of the first inclined plate 503 and the top surface of the second inclined plate 504 are both inclined surfaces. In addition, along the first direction a, the height of each point on the first inclined plate 503 gradually decreases, and the height of each point on the second inclined plate 504 gradually increases. The free end of the second inclined plate 504 is the toggle end of the lever 5.

[0065] In order to realize the rotation of the lever 5 around the third axis, Figures 1 to 6 As shown, the optical disc ejection device also includes a rotating support mechanism 8, which includes a rotating rod 802 and two support seats 801 arranged at intervals. The central axis of the rotating rod 802 is the third axis, and the third axis is arranged horizontally. The two ends of the rotating rod 802 are respectively connected to the two support seats 801, and the abutting end of the lever 5 is rotatably connected to the rotating rod 802.

[0066] Furthermore, if Figures 1 to 6As shown, the optical disc ejection device further includes an elastic member 7, one end of which is fixedly connected to the bottom plate 10, and the other end is connected to the abutting end of the lever 5. In order to achieve the connection between the elastic member 7 and the bottom plate 10, a avoidance hole 403 is provided on the slide plate 4, and one end of the elastic member 7 passes through the avoidance hole 403 and is fixedly connected to the bottom plate 10.

[0067] Optionally, the reset elastic body is a coil spring. Figure 3 When the lever 5 is in the lowest position shown in FIG. 1 , the abutting end of the lever 5 is raised, the coil spring is in a stretched state, and a certain amount of elastic potential energy is accumulated; when the lever 5 is in the lowest position shown in FIG. Figure 3 The least significant bit shown switches to Figure 6 When the lever 5 is in the highest position, the contact end of the lever 5 drops, and the coil spring gradually recovers from the stretched state to the original length state. Under the elastic force of the coil spring, the contact end of the lever 5 can be quickly lowered, thereby realizing the rapid lifting of the lever end, improving the efficiency of the optical disc ejection and avoiding the hysteresis phenomenon. Of course, in addition to the coil spring, other elastic elastic bodies can also be used as the elastic member 7.

[0068] In order to ensure that the lever 5 can accurately move the target optical disc, Figures 1 to 6 As shown, the optical disc ejection device further includes a centering mechanism, which can center the lever 5, even if the lever 5 is located in the middle of the two support seats 801. Specifically, the centering mechanism includes two centering elastic bodies 9, both of which are sleeved on the rotating rod 802 and are respectively located on both sides of the frame portion 502 of the lever 5, one end of the centering elastic body 9 elastically abuts against the outer wall surface of the frame portion 502, and the other end elastically abuts against the inner wall surface of the support seat 801. Optionally, the centering elastic body 9 is a coil spring sleeved on the rotating rod 802.

[0069] When the lever 5 is deflected during the rotation around the third axis, the centering elastic body 9 on one side thereof will be compressed, and the centering elastic body 9 on the other side thereof will be stretched, and the two centering elastic bodies 9 will generate elastic forces in the same direction, which can drive the lever 5 to return to the middle position. In addition, the setting of the centering elastic body 9 can also provide appropriate damping for the lifting and pressing of the lever 5, so that the movement stability of the lever 5 is improved.

[0070] Compared with the existing CD ejection device, this CD ejection device is not only compact and small in structure and has high working reliability, but also can lift and eject the CD without manual operation. It has a high degree of automation and high efficiency in CD removal, which saves users time and effort and provides a high user experience.

[0071] This embodiment also provides an optical disc storage device, which includes an optical disc storage rack and the above optical disc ejection device, wherein the optical disc storage rack is used to store multiple optical discs, and the optical disc ejection device is used to eject a target optical disc on the optical disc storage rack. The optical disc storage device has a high degree of automation, and the user has a high efficiency in taking optical discs, which saves time and effort and provides a high experience.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
