The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

In order to describe the technical scheme of the application, the following description is made with reference to specific drawings and embodiments.

The embodiment of the application provides a hard disk mechanism which can be used for compatibly placing two hard disks with different sizes.

Referring to fig. 1 to 5 and fig. 10, in an embodiment of the application, the hard disk mechanism 100 includes a base 10, a transmission member 20 disposed on the base 10, a first moving member 30 slidably connected to the base 10 along a first direction (X direction in the drawing) and a second moving member 40 slidably connected to the base 10 along a second direction (a direction in the drawing), wherein the second direction a forms an included angle with the first direction X, and the degree of the included angle is not limited. The first moving member 30 and the second moving member 40 are in transmission connection with the transmission member 20, and a space 101 for placing the hard disk 200 is formed among the base 10, the first moving member 30 and the second moving member 40. It will be appreciated that the shape of the space 101 for placing the hard disk 200 is adapted to the shape of the hard disk 200, and the length of the space 101 is slightly larger than the hard disk 200, so as to facilitate the installation of the hard disk 200.

The hard disk mechanism 100 includes a first state and a second state, and in the process of the hard disk mechanism 100 from the first state to the second state, the first moving member 30 slides along the first direction X and is away from the base 10, the first moving member 30 slides to drive the driving member 20 to move, and the driving member 20 moves to drive the second moving member 40 to move along the second direction a and away from the base 10. Accordingly, in the process of moving the hard disk mechanism 100 from the second state to the first state, the first moving member 30 slides along the first direction X and approaches the base 10, at this time, the first moving member 30 can drive the driving member 20 to move, and the driving member 20 can drive the second moving member 40 to move along the second direction a and approach the base 10.

It is understood that the size of the space 101 when the hard disk mechanism 100 is in the first state is smaller than the size of the space 101 when the hard disk mechanism 100 is in the second state. Specifically, the hard disk mechanism 100 is in a closed state when in the first state, and is used for placing the small-sized hard disk 200; the hard disk mechanism 100 is in the second state in an open state for placing the large-sized hard disk 200.

The hard disk mechanism 100 includes a base 10, a transmission member 20, a first moving member 30, and a second moving member 40, where the first moving member 30 and the second moving member 40 are in transmission connection with the transmission member 20, and the movements of the first moving member 30 and the second moving member 40 are synchronous; because the first moving member 30 is slidably connected to the base 10 along the first direction X, the second moving member 40 is slidably connected to the base 10 along the second direction a, and when the first moving member 30 is forced to move along the first direction X, the driving member 20 is driven to move, and the moving driving member 20 can drive the second moving member 40 to move along the second direction a, so that synchronous opening or closing of the hard disk mechanism 100 is realized, and thus, the size of the space 101 for accommodating the hard disk 200 is changed to be compatible with the hard disk 200 installed in different sizes, and the technical problems that the hard disk mechanism in the prior art cannot be compatible with the hard disk in different sizes and has poor universality are solved.

To accommodate the existing 2.5 inch and 3.5 inch universal hard disk 200, the space 101 for mounting the hard disk 200 on the hard disk mechanism 100 is rectangular, and the hard disk mechanism 100 includes a long side 102 and a wide side 103 connected. It will be appreciated that the length of the long side 102 and the wide side 103 is changed during the movement of the first moving member 30 and the second moving member 40 to achieve the expansion and contraction of the size of the space 101.

Referring to fig. 1 to 4, in an embodiment of the application, the hard disk mechanism 100 further includes a third moving member 50 slidably connected to the base 10 along a third direction (Y direction shown in the drawing), the third direction Y is perpendicular to the first direction X, the third moving member 50 is in driving connection with the driving member 20, and the driving member 20 is further used for driving the third moving member 50 to move along the third direction Y to approach or separate from the base 10.

Wherein, the first direction X, the second direction A and the third direction Y are all positioned in the same plane. At this time, a space 101 for placing the hard disk 200 is commonly formed among the base 10, the first moving member 30, the second moving member 40, and the third moving member 50.

Referring further to fig. 8 to 10, in the present embodiment, the transmission member 20 includes a first gear set 21 and a second gear set 22. The first gear set 21 includes a first rotating shaft 211, a first upper gear 212 and a first lower gear 213 coaxially and fixedly connected to the first rotating shaft 211, and it can be understood that the first upper gear 212 and the first lower gear 213 rotate synchronously, and the rotation directions of the first upper gear 212 and the first lower gear 213 are the same. The first lower gear 213 is in driving connection with the first moving member 30, and the first upper gear 212 is in driving connection with the second moving member 40.

The second gear set 22 includes a second rotating shaft 221, a second upper gear 222 and a second lower gear 223 coaxially and fixedly connected to the second rotating shaft 221, and it can be understood that the second upper gear 222 and the second lower gear 223 rotate synchronously, and the rotation directions of the second upper gear 222 and the second lower gear 223 are the same. The second lower gear 223 is meshed with the first lower gear 213, the second upper gear 222 is drivingly connected to the third moving member 50, and the first rotation axis 211 is parallel to the second rotation axis 221. The first gear set 21 and the second gear set 22 are manufactured through an open mold injection molding process, and a material adopts Polyoxymethylene (POM).

Thus, the positions of the first moving member 30, the second moving member 40 and the third moving member 50 are adjusted through the cooperation between different gears, the transmission is accurate and efficient, the working reliability is high, the service life is long, and the durability of the hard disk mechanism 100 is improved.

Referring to fig. 1 to 4, in the present embodiment, the first moving member 30 is capable of moving along the long side 102 of the hard disk mechanism 100, i.e. the first direction X is parallel to the length direction of the hard disk mechanism 100; the third mover 50 is movable along the wide side 103 of the hard disk mechanism 100, i.e., the third direction Y is parallel to the width direction of the hard disk mechanism 100. Because the second direction a is set at an included angle with the first direction X and the third direction Y, and the first direction X is perpendicular to the third direction Y, the moving distance of the second moving member 40, the moving distance of the first moving member 30, and the moving distance of the third moving member 50 are sequentially reduced in the switching process of the first state and the second state of the hard disk mechanism 100. Since the movements of the first, second and third moving members 30, 40 and 50 and the transmission member 20 are synchronized, the diameter of the first upper gear 212, the diameter of the first lower gear 213, and the diameter of the second upper gear 222 are sequentially reduced. In this way, the degree of expansion and contraction of the hard disk mechanism 100 can be precisely controlled by adjusting the transmission ratio of the first gear set 21 and the second gear set 22.

It will be appreciated that, in other embodiments of the present application, the first moving member 30 may also move along the wide edge 103 of the hard disk mechanism 100, i.e. the first direction X is parallel to the width direction of the hard disk mechanism 100, and then the third direction Y is parallel to the length direction of the hard disk mechanism 100, and the moving distance of the second moving member 40, the moving distance of the third moving member 50, and the moving distance of the first moving member 30 sequentially decrease during the switching process of the first state and the second state of the hard disk mechanism 100. Correspondingly, the diameter of the first upper gear 212, the diameter of the second upper gear 222, and the diameter of the first lower gear 213 decrease in order.

The first upper gear 212, the second upper gear 222 and the first lower gear 213 are disposed at intervals along a fourth direction (Z direction in the drawing), and the fourth direction Z is perpendicular to the first direction X and the third direction Y, that is, the first upper gear 212, the second upper gear 222 and the first lower gear 213 are disposed at intervals along the thickness direction of the hard disk mechanism 100, so that any two of the first moving member 30, the second moving member 40 and the third moving member 50 do not interfere with each other, and jamming is avoided.

It will be appreciated that the structure of the transmission member 20 is not unique, for example, in other embodiments of the present application, the second lower gear 223 may also be meshed with the first upper gear 212, and the third moving member 50 and the second moving member 40 may be moved synchronously by changing the diameter ratio of the second upper gear 222 and the second lower gear 223, which is not limited herein. Alternatively, the driving member 20 may be a sliding rail, a sliding block, or other structures, but is not limited thereto.

Referring to fig. 3 and 11 to 13, in an embodiment of the present application, a first moving member 30 is provided with a first synchronizing tooth 31 extending along a first direction X, and the first synchronizing tooth 31 is meshed with a first lower gear 213; the second moving member 40 is provided with a second synchronizing tooth 41 extending along the second direction a, and the second synchronizing tooth 41 is meshed with the first upper gear 212; the third moving member 50 is provided with a third synchronizing tooth 51 extending in the third direction Y, and the third synchronizing tooth 51 is engaged with the second upper gear 222. Thus, the first, second and third moving members 30, 40, 50 move smoothly, and the transmission accuracy is high.

Wherein the first synchronizing tooth 31, the second synchronizing tooth 41 and the third synchronizing tooth 51 each include a plurality of tooth grooves, it is understood that the distance traveled by the first lower gear 213 on the first synchronizing tooth 31 is equal to the stroke of the first moving member 30; the distance travelled by the second upper gear 222 on the third synchronizing tooth 51 is equal to the travel of the third mobile 50; the distance traveled by the first upper gear 212 on the second synchronizing tooth 41 is equal to the travel of the second mobile 40.

Referring to fig. 1, 6 and 7, in an embodiment of the present application, a base 10, a first moving member 30, a second moving member 40 and a third moving member 50 are sequentially connected end to end, and two ends of the base 10 are respectively slidably connected to the first moving member 30 and the third moving member 50; both ends of the second moving member 40 are slidably connected to the first moving member 30 and the third moving member 50, respectively. In this way, in the opening and closing process of the hard disk mechanism 100, the opposite ends of the first moving member 30, the second moving member 40 and the third moving member 50 are limited to be slidably connected with the adjacent structures, so that random shaking or rotation is avoided, the degree of expansion and deformation of the hard disk mechanism 100 after the hard disk mechanism is opened or closed for many times is kept consistent, and the expansion and contraction precision of the hard disk mechanism 100 is improved.

Specifically, the base 10, the first moving member 30, the second moving member 40, and the third moving member 50 each include a supporting portion 61 and two plugging portions 62 vertically connected to the supporting portion 61, and the two plugging portions 62 are vertically connected. After the hard disk 200 is mounted to the hard disk mechanism 100, the side wall of the hard disk 200 is disposed opposite to the insertion portion 62. The two plug-in parts 62 of the base 10 are respectively connected with one plug-in part 62 of the first moving member 30 and one plug-in part 62 of the third moving member 50 in a sliding manner; the two insertion parts 62 of the second moving member 40 are slidably connected with the other insertion part 62 of the first moving member 30 and the other insertion part 62 of the third moving member 50, respectively. In the present embodiment, in the two slidably connected plug-in parts 62, a sliding groove 63 is provided on one plug-in part 62, and the other plug-in part 62 is inserted into the sliding groove 63 and slides along the length direction of the sliding groove 63. Taking the base 10 and the first moving member 30 as an example, a sliding groove 63 is disposed on an insertion portion 62 of the first moving member 30 facing the base 10, and the insertion portion 62 of the base 10 facing the first moving member 30 is inserted into the sliding groove 63. Similarly, the two plug-in portions 62 of the other sliding connection can be slidably engaged in this manner, which is not described here again.

In addition, when the hard disk mechanism 100 is in the first state, referring to fig. 1, 6 and 7, the supporting portion 61 of the base 10, the supporting portion 61 of the first moving member 30, the supporting portion 61 of the second moving member 40 and the supporting portion 61 of the third moving member 50 are stacked along the fourth direction Z, so as to avoid interference.

Referring to fig. 1 and 2, in an embodiment of the present application, a limiting assembly is disposed between adjacent two of the base 10, the first moving member 30, the second moving member 40 and the third moving member 50, and the limiting assembly includes a limiting post 64 and a bar slot 65, wherein the limiting post 64 is disposed in the bar slot 65 in a penetrating manner and slides along the length direction of the bar slot 65. In this way, the limit post 64 and the bar-shaped groove 65 are matched for use, so that the moving tracks of the first moving member 30, the second moving member 40 and the third moving member 50 are further restrained and controlled, and the failure of the connection between the adjacent two of the base 10, the first moving member 30, the second moving member 40 and the third moving member 50 is avoided.

Specifically, taking the base 10 and the first moving member 30 as an example, referring to fig. 6 and 7 in combination, a through hole 66 is formed in the plugging portion 62 of the base 10, a bar-shaped groove 65 is formed in the plugging portion 62 of the first moving member 30, a limiting post 64 sequentially penetrates through the through hole 66 and the bar-shaped groove 65, and the limiting post 64 is in threaded connection with the through hole 66, so as to define a movement track of the first moving member 30 and avoid derailment of the first moving member 30. To further improve the stroke accuracy of the first moving member 30, the length of the bar-shaped groove 65 is the same as the stroke length of the first moving member 30. Similarly, a limiting component is also disposed between other adjacent two of the base 10, the first moving member 30, the second moving member 40 and the third moving member 50, which is not described in detail.

In order to further improve the connection stability between the hard disk mechanism 100 and the hard disk 200 in the first state or the second state, referring to fig. 1 to 3 and 5, in an embodiment of the present application, the hard disk mechanism 100 may further include a plurality of screws 67, the hard disk 200 is provided with threaded holes, the base 10, the first moving member 30, the second moving member 40 and the third moving member 50 are provided with through holes 68, and after the hard disk 200 is mounted to the hard disk mechanism 100, the screws 67 sequentially penetrate through the through holes 68 and the threaded holes to lock the hard disk 200.

Specifically, the insertion portions 62 of the base 10, the first moving member 30, the second moving member 40, and the third moving member 50 are provided with through holes 68, and the side walls of the hard disk 200 are provided with threaded holes. The specific positions of the through hole 68 and the threaded hole are not unique, and only the through hole 68 and the corresponding threaded hole are required to be arranged opposite to each other in the first state and the second state.

It is understood that in other embodiments of the present application, the third mover 50 may be omitted. Taking the movement of the first moving member 30 along the long side 102 of the hard disk mechanism 100 as an example, when the hard disk mechanism 100 is in the first state, one side of the base 10 is equal to the wide side 103 of the hard disk mechanism 100, one end of the second moving member 40 away from the first moving member 30 extends to the end of the base 10, and after the first moving member 30 is stressed and drives the second moving member 40 to move to the second state, a gap exists between one end of the second moving member 40 away from the first moving member 30 and the base 10, so that the installation of the large-size hard disk 200 is not affected.

Referring to fig. 1 and 2, in an embodiment of the present application, the hard disk mechanism 100 further includes a hard disk cord plug 70 fixedly mounted on the base 10, and the hard disk cord plug 70 is used for electrically connecting to the hard disk 200. In this way, the position of the hard disk cord plug 70 is not changed in the process of switching the first state and the second state of the hard disk mechanism 100, so as to avoid affecting the on-off of the internal circuit of the hard disk cord plug 70 and the connection on-off of the hard disk 200.

Specifically, the hard disk line plug 70 is inserted through the base 10, one end of the hard disk line plug 70 extends to the external space, the other end extends to the space 101, an interface is provided at the end of the hard disk line plug 70 extending to the space 101, and when the hard disk 200 is placed in the space 101, the interface on the hard disk 200 can be directly docked with the interface to realize data transmission. Alternatively, in other embodiments, the hard disk cord plug 70 is fixedly mounted on the base 10, and the base 10 is provided with a socket, and the plug of the hard disk 200 may be electrically connected to the hard disk cord plug 70 through the socket, which is not limited herein.

Specifically, when the hard disk mechanism 100 is in the first state, the 2.5 inch hard disk 200 is aligned with the hard disk line plug 70, and the hard disk 200 and the hard disk line plug 70 are tightly inserted from right to left; the 2.5 inch hard disk 200 is then locked to the hard disk mechanism 100 with screws 67.

Referring to fig. 1 and 6, in an embodiment of the application, the hard disk mechanism 100 further includes a shielding member 90 fixedly connected to the base 10, an accommodating space is defined between the shielding member 90 and the base 10, and the driving member 20 is accommodated in the accommodating space, so as to protect the driving member 20 and reduce the possibility of damaging the driving member 20 by external force.

Specifically, to avoid affecting the transmission connection between the transmission member 20 and the first moving member 30, the second moving member 40, and the third moving member 50, the shielding member 90 includes only a top cover 91 and a connecting piece 92 that are connected in a bending manner, and one end of the connecting piece 92 away from the top cover 91 is fixedly connected with the base 10, that is, three sides of the shielding member 90 are not shielded.

In addition, if the supporting portion 61 of the base 10, the supporting portion 61 of the first moving member 30, the supporting portion 61 of the second moving member 40, and the supporting portion 61 of the third moving member 50 are respectively located in the middle region of the corresponding insertion portion 62 along the fourth direction Z, two spaces 101 are formed between the base 10, the first moving member 30, and the second moving member 40, the two spaces 101 are spaced apart along the fourth direction Z, one space 101 is used for placing the hard disk 200, and the other space 101 is used for placing the first holder 11, the transmission member 20, the expansion member 80, the shielding member 90, and the like.

In one embodiment of the present application, the hard disk mechanism 100 changes the movement mode from the second state to the first state, so that the first moving member 30 moves in a direction approaching the base 10, that is, the first moving member 30 moves to the left in a stressed state, and the expansion member 80 is compressed. Synchronously, the first lower gear 213 rotates clockwise around the first axis L1, and the first upper gear 212 also rotates clockwise around the first axis L1 and drives the second moving member 40 to approach the base 10 along the second direction; since the second lower gear 223 is meshed with the first lower gear 213, when the first lower gear 213 rotates clockwise, the second lower gear 223 rotates counterclockwise, and the second upper gear 222 also rotates counterclockwise synchronously and drives the third moving member 50 to move along the third direction near the base 10 until the hard disk mechanism 100 is in the first state. At this time, the catch portion 112 of the first catch 11 catches the second catch 32 on the first mover 30, and the hard disk mechanism 100 is tightened.

The base 10, the first moving member 30, the second moving member 40, the third moving member 50, the first clamping member 11, the shielding member 90, etc. may also be formed by a mold opening injection molding process, and the material is glass fiber reinforced PC.

The hard disk mechanism 100 can be opened or closed synchronously, so that the size of the space 101 for placing the hard disk 200 is changed to be compatible with the hard disk 200 with different sizes, and the technical problem that the hard disk mechanism in the prior art cannot be compatible with the hard disk with different sizes and has poor universality is solved.

The above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application.
