[0021] In the above solution, the hard drive enclosure structure includes a hard drive board, a hard drive bracket, a first hard drive, and a second hard drive. The hard drive board is fixed to the hard drive bracket and divides the hard drive bracket into a first space and a second space. The first hard drive and the second hard drive are plugged into the first space and the second space, respectively. The hard drive enclosure structure provided by this utility model has a simple structural layout and is easy to assemble. When the hard drives need to be removed or installed, the first hard drive and the second hard drive can be pulled out of the first space and the second space, respectively, facilitating maintenance and replacement of the hard drives.

[0039] Vehicle video recorders (VDRs) are installed in various vehicles and provide functions such as GPS positioning, in-vehicle entertainment playback, and wireless network transmission. They consist of a main unit and a hard drive enclosure, the primary component of which is the hard drive. Some enclosures contain dual hard drives, resulting in a complex enclosure structure and assembly, and the hard drives are difficult to remove.

[0040] In order to solve the above technical problems, the present utility model proposes a new hard disk box structure 100 and a vehicle-mounted video recorder. The hard disk box structure 100 includes a hard disk board 20, a hard disk bracket 10, a first hard disk 30 and a second hard disk 40. The hard disk board 20 is installed on the hard disk bracket 10, dividing the hard disk bracket 10 into a first space and a second space. The first hard disk 30 and the second hard disk 40 are respectively plugged into the first space and the second space, making it very convenient to disassemble and assemble the hard disks. In addition, the hard disk box structure 100 is simple and easy to assemble.

[0041] The hard disk enclosure structure 100 provided in an embodiment of the present invention is now described.

[0042] Please also refer to Figures 1 to 4 The hard disk box structure 100 includes a hard disk board 20, a hard disk bracket 10, a first hard disk 30 and a second hard disk 40.

[0043] The hard drive bracket 10 is the internal support and mounting structure of the hard drive enclosure structure 100. The hard drive board 20, the first hard drive 30, and the second hard drive 40 are all mounted on the hard drive bracket 10. The hard drive bracket 10 defines a receiving cavity and has a mounting portion 115 inside it for securing the hard drive board 20.

[0044] The hard disk board 20 can be understood as a circuit board electrically connected to the hard disk. A first connector and a second connector 22 are respectively provided on opposite sides of the hard disk board 20. The first connector and the second connector 22 are both fixed and electrically connected to the hard disk board 20. The hard disk board 20 is located inside the hard disk bracket 10 and is mounted on the mounting portion 115 of the hard disk bracket 10. The hard disk bracket 10 forms a first space and a second space on opposite sides of the hard disk board 20. In other words, the accommodating cavity of the hard disk bracket 10 is divided into a first space and a second space. The first space is used to accommodate the first hard disk 30, and the second space is used to accommodate the second hard disk 40. The first connector is located in the first space, and the second connector 22 is located in the second space.

[0045] Both the first hard drive 30 and the second hard drive 40 are memories capable of storing and accessing data. The first hard drive 30 has a first terminal that plugs into the first connector, and the second hard drive 40 has a second terminal 41 that plugs into the second connector 22. When the first hard drive 30 is inserted into the first compartment, the first terminal and the first connector plug into each other, establishing electrical connection between the first hard drive 30 and the hard drive board 20. When the second hard drive 40 is inserted into the second compartment, the second terminal 41 and the second connector 22 plug into each other, establishing electrical connection between the second hard drive 40 and the hard drive board 20.

[0046] When the first hard disk 30 and the second hard disk 40 need to be disassembled, the first hard disk 30 and the second hard disk 40 can be pulled out from the hard disk bracket 10 . Therefore, the disassembly and assembly of the first hard disk 30 and the second hard disk 40 is very convenient.

[0047] The hard drive enclosure structure 100 in the above embodiment includes a hard drive board 20, a hard drive bracket 10, a first hard drive 30, and a second hard drive 40. The hard drive board 20 is fixed to the hard drive bracket 10 and divides the hard drive bracket 10 into a first space and a second space. The first hard drive 30 and the second hard drive 40 are respectively inserted into the first space and the second space. The hard drive enclosure structure 100 provided by the present invention has a simple structural layout and is easy to assemble. When the hard drives need to be removed or installed, the first hard drive 30 and the second hard drive 40 can be pulled out of the first space and the second space, respectively, facilitating maintenance and replacement of the hard drives.

[0048] In some embodiments of the present invention, please refer to Figures 4 to 6The first and second hard drives 30 and 40 are inserted in a first direction, and a direction perpendicular to the first direction is a second direction. The hard drive bracket 10 includes two bracket units 11 arranged opposite each other in the second direction. The bracket unit 11 includes a side panel 111, a mounting portion 115, and a first and second limiting plates 112 and 113 connected to opposite sides of the side panel 111. The mounting portion 115 is disposed on the side panel 111 and located between the first and second limiting plates 112 and 113. A first space is formed between the first limiting plate 112 and the hard drive board 20, and a second space is formed between the second limiting plate 113 and the hard drive board 20. The first and second hard drives 30 and 40 move in the first direction during assembly and disassembly. The second direction is perpendicular to the first direction. The third direction is perpendicular to both the first and second directions and is the thickness direction of the hard drive board 20. The two bracket units 11 are disposed on opposite sides of the hard drive board 20 in the second direction, respectively, to position the hard drive board 20 in the second direction. In the third direction, the first limiting plate 112, the mounting portion 115, and the second limiting plate 113 are sequentially arranged. The hard disk board 20 is mounted on one mounting portion 115 on one side of the first direction, and the hard disk board 20 is mounted on the other mounting portion 115 on the other side of the second direction. When the first hard disk 30 and the second hard disk 40 are both mounted on the hard disk bracket 10, the first hard disk 30, the hard disk board 20, and the second hard disk 40 are stacked sequentially in the third direction.

[0049] The first limiting plate 112, a portion of the side plate 111, and the hard disk board 20 form a first track that guides one side of the first hard disk 30. The two bracket units 11 can guide both sides of the first hard disk 30, allowing the first hard disk 30 to slide along the first track into the first space. The second limiting plate 113, a portion of the side plate 111, and the hard disk board 20 form a second track that guides one side of the second hard disk 40. The two bracket units 11 can guide both sides of the second hard disk 40, allowing the second hard disk 40 to slide along the second track into the second space.

[0050] The hard disk bracket 10 includes two bracket units 11, so a limiting structure can be set on both opposite sides of the second direction, and the first hard disk 30 and the second hard disk 40 can be limited in the second direction. The first limiting plate 112 of the bracket unit 11 limits the first hard disk 30 in the third direction, and the second limiting plate 113 of the bracket unit 11 limits the second hard disk 40 in the third direction, so that the first hard disk 30 and the second hard disk 40 can only move in the first direction.

[0051] In some embodiments, the two bracket units 11 are separately provided, that is, the two bracket units 11 are manufactured and formed separately, and are respectively installed on opposite sides of the hard disk board 20 .

[0052] By setting the two bracket units 11 separately, the transportation volume of the hard disk bracket 10 can be reduced, the processing difficulty of the hard disk bracket 10 can be reduced, and the installation and matching between the hard disk bracket 10 and the hard disk board 20 can be easier.

[0053] Optionally, both bracket units 11 are provided with an identification portion 12. When the structures of the two bracket units 11 are not identical, the two bracket units 11 can be distinguished and the bracket units 11 can be prevented from being installed upside down. For example, the two bracket units 11 are marked with "Left" and "Right" respectively, and are installed on the left and right sides of the hard disk board 20 (opposite sides in the second direction). Alternatively, the two bracket units 11 are marked with "L" and "R" respectively, and are installed on the left and right sides of the hard disk board 20 (opposite sides in the second direction).

[0054] In other embodiments, the two bracket units 11 may also be connected to each other so that the hard disk bracket 10 is an integral structure.

[0055] In some embodiments, please participate Figure 3 、 Figure 5 and Figure 6 The mounting portion 115 includes a mounting slot 116 extending along a first direction and a fixing portion 117 for fixing the hard disk board 20. The side wall of the hard disk board 20 is located in the mounting slot 116, and a connecting ear 24 is provided on the side wall of the hard disk board 20. The connecting ear 24 passes through the side panel 111 and is arranged opposite the fixing portion 117. The mounting slot 116 is used to limit the hard disk board 20 in the second and third directions, and the fixing portion 117 is used to fix the hard disk board 20 and the bracket unit 11. Specifically, the two mounting slots 116 of the two bracket units 11 respectively accommodate opposite sides of the hard disk board 20 in the second direction. When the hard disk bracket 10 is installed on the hard disk board 20, the two bracket units 11 are respectively connected to the two sides of the hard disk board 20 in the second direction through the mounting slots 116. At the same time, the connecting ear 24 on the hard disk board 20 passes through the avoidance hole 118 on the side panel 111 to face the fixing portion 117, facilitating the connection between the fixing portion 117 and the connecting ear 24. In this embodiment, the two bracket units 11 are provided separately, so that the two connecting ears 24 can pass through the corresponding side plates 111 .

[0056] By setting the mounting slot 116, the side of the hard disk board 20 can be clipped into the bracket unit 11, and by setting the fixing portion 117, the connecting ear 24 on the hard disk board 20 and the fixing portion 117 can be fixed to each other, thereby realizing the mutual connection between the hard disk board 20 and the bracket unit 11.

[0057] In some embodiments, see Figure 3The fixing portion 117 and the connecting ear 24 are fixedly connected by a first connecting member 51. There are multiple first connecting members 51, and they are arranged asymmetrically. Specifically, both the connecting ear 24 and the fixing portion 117 have connecting holes. The first connecting member 51 passes through the connecting hole in the connecting ear 24 and connects with the connecting hole in the fixing portion 117, thereby fixing the hard disk board 20 and the bracket unit 11 to each other. The asymmetrical arrangement of the multiple first connecting members 51 refers to the non-centrally and axially symmetrical distribution of the multiple first connecting members 51.

[0058] The presence of multiple first connectors 51 stabilizes the connection between the hard disk board 20 and the bracket unit 11. The asymmetrical arrangement of the multiple first connectors 51 prevents the connection holes on the connecting ears 24 from aligning with the connection holes on the fixing portion 117 when the bracket unit 11 is installed upside down, thus preventing errors.

[0059] Optionally, there are four first connecting members 51 , which are respectively disposed at four corners of the hard disk board 20 .

[0060] In some embodiments of the present invention, please refer to Figure 3 The hard disk bracket 10 is provided with a first limiting portion in the first space for limiting the position of the first hard disk 30 in the first direction; and / or, the hard disk bracket 10 is provided with a second limiting portion 13 in the second space for limiting the position of the second hard disk 40 in the first direction. This embodiment includes the following three situations: the hard disk bracket 10 is provided with a first limiting portion for limiting the position of the first hard disk 30 in the first direction. When the first hard disk 30 is inserted into the first space and reaches a predetermined position, the first limiting portion abuts the first hard disk 30 to prevent the first hard disk 30 from being out of position and causing damage to the first connector and the first terminal; the hard disk bracket 10 is provided with a second limiting portion 13 for limiting the position of the second hard disk 40 in the second direction. When the second hard disk 40 is inserted into the second space and reaches a predetermined position, the second limiting portion 13 abuts the second hard disk 40 to prevent the second hard disk 40 from being out of position and causing damage to the second connector 22 and the second terminal 41; the hard disk bracket 10 is provided with both the first limiting portion and the second limiting portion 13.

[0061] By providing the first limiting portion and / or the second limiting portion 13 , the first hard disk 30 and the second hard disk 40 can be limited during installation, thereby preventing the hard disks from being out of position and causing damage to the connectors and terminals.

[0062] In some embodiments, there are two first limiting portions, which are respectively disposed on two opposite sides of the hard disk bracket 10 in the second direction, thereby stopping both sides of the first hard disk 30 .

[0063] In some embodiments, there are two second limiting portions 13 , which are respectively disposed on two opposite sides of the hard disk bracket 10 in the second direction, thereby stopping both sides of the second hard disk 40 .

[0064] In some embodiments of the present invention, please refer to Figure 3 The hard disk board 20 is provided with a disassembly hole 23 at one end near the first connector for convenient disassembly of the first hard disk 30 and / or the second hard disk 40. The disassembly hole 23 is set through the hard disk board 20. A disassembly tool such as a finger can be inserted into the disassembly hole 23 to apply a disassembly force to the first hard disk 30 and the second hard disk 40, so that the first hard disk 30 and the second hard disk 40 move in the first direction. After the first hard disk 30 and the second hard disk 40 are partially removed from the hard disk bracket 10, the first hard disk 30 and the second hard disk 40 can be directly pulled out.

[0065] The disassembly hole 23 is provided to facilitate insertion of disassembly tools such as fingers into the disassembly hole 23 to apply force to the first hard disk 30 and / or the second hard disk 40 , thereby facilitating disassembly of the first hard disk 30 and / or the second hard disk 40 .

[0066] In some embodiments, there is only one disassembly hole 23 , and a finger inserted into the disassembly hole 23 can push the first hard disk 30 and the second hard disk 40 at the same time.

[0067] In some embodiments, there are two disassembly holes 23 . When fingers are inserted into the two disassembly holes 23 , the first hard disk 30 and the second hard disk 40 can be pushed respectively.

[0068] In some embodiments of the present invention, please refer to Figures 2 to 4 The first hard disk 30 is connected to the hard disk board 20 via the second connecting member 52, and the second hard disk 40 is connected to the hard disk bracket 10 via the third connecting member 53. Specifically, a first connecting hole is defined on the hard disk board 20, and a second connecting hole is defined on the first hard disk 30. The second connecting member 52 passes through the first connecting hole and connects with the second connecting hole, thereby achieving mutual connection between the first hard disk 30 and the hard disk board 20. A third connecting hole 119 is defined on the hard disk bracket 10, and a fourth connecting hole is defined on the second hard disk 40. The third connecting member 53 passes through the third connecting hole 119 and connects with the fourth connecting hole, thereby achieving mutual connection between the second hard disk 40 and the hard disk bracket 10.

[0069] The first hard disk 30 and the hard disk board 20 are connected via the second connecting member 52, and the second hard disk 40 and the hard disk bracket 10 are connected via the third connecting member 53, so that the first hard disk 30 and the second hard disk 40 can be stably mounted on the hard disk bracket 10. Even under vibration conditions, the first hard disk 30 and the second hard disk 40 will not become loose from the hard disk bracket 10.

[0070] When removing the first hard drive 30, first loosen the second connecting member 52, then push the first hard drive 30 in the first direction to disengage the first connector and the first terminal, and then pull out the first hard drive 30. When removing the second hard drive 40, first loosen the third connecting member 53, then push the second hard drive 40 in the first direction to disengage the second connector 22 and the second terminal 41, and then pull out the second hard drive 40.

[0071] In some embodiments, the second limiting portion 13 of the hard disk bracket 10 and the second hard disk 40 are connected to each other via a third connecting member 53. The second limiting portion 13 is provided with the third connecting hole 119 mentioned above.

[0072] In some embodiments, there are multiple second connectors 52 to stabilize the connection between the first hard disk 30 and the hard disk board 20. For example, there are four second connectors 52, each disposed at one of the four corners of the first hard disk 30.

[0073] In some embodiments, there are multiple third connectors 53 to stabilize the connection between the second hard disk 40 and the hard disk bracket 10. For example, there are four third connectors 53, each disposed at one of the four corners of the second hard disk 40.

[0074] Optionally, in the first direction, one of the third connecting holes 119 is a round hole, and the other third connecting hole 119 is a waist-shaped hole. In this way, even if there are processing and assembly errors, the third connecting member 53 can pass through the third connecting hole 119.

[0075] In some embodiments, see Figure 4 A third limiting plate 114 is also provided on the side plate 111. A second track is formed between the second limiting plate 113 and the third limiting plate 114. The side surface of the second hard disk 40 extends into the second track, thereby guiding the insertion and removal of the second hard disk 40. The third limiting plate 114 is provided between the second limiting plate 113 and the hard disk board 20.
