DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0038] A hard disk recorder is a device that records video signals. Its main functions include video storage, video playback and replay, remote monitoring, and alarm functions. A hard disk recorder can use a mechanical hard disk or a solid-state hard disk. The cost of a solid-state hard disk is relatively high. In order to save costs, a mechanical hard disk can be selected, but a mechanical hard disk has high requirements for heat dissipation, so a heat dissipation structure needs to be designed accordingly. In order to ensure the heat dissipation performance of the heat dissipation structure, thermal conductive foam is generally used for contact heat dissipation. Therefore, during the assembly process of the hard disk recorder, the thermal conductive foam inevitably needs to rub against the radiator, hard disk module, etc., which makes its installation steps complicated and may also cause material loss such as thermal conductive foam during the installation process.

[0039] In order to alleviate the above technical problems, the present invention proposes a hard disk installation structure 100 and a hard disk video recorder. The hard disk installation structure 100 includes a hard disk module 10 and a hard disk radiator 20. The hard disk module 10 is inserted into the accommodation space 22 of the hard disk radiator 20. The width of the hard disk module 10 gradually decreases in its insertion direction, and the accommodation space 22 is adapted to the shape of the hard disk module 10. In this way, in the process of gradually inserting the hard disk module 10 into the hard disk radiator 20, the distance between the opposite sides of the hard disk module 10 and the side walls of the accommodation space 22 gradually decreases. Only in the final stage of assembly completion, the heat conductive structures 12 on both sides of the hard disk module 10 are in contact and squeezed with the side walls of the accommodation space 22, so that the heat generated by the hard disk body 11 can be transferred to the hard disk radiator 20 through the heat conductive structure 12, and has good heat dissipation performance.

[0040] The hard disk installation structure 100 provided in the embodiment of the present invention is now described.

[0041] Please also read Figures 1 to 4 The hard disk installation structure 100 includes a hard disk module 10 and a hard disk radiator 20 , and the hard disk module 10 is installed on the hard disk radiator 20 .

[0042] The hard disk radiator 20 is made of a material with good thermal conductivity, and can quickly transfer the heat transferred from the hard disk module 10 to the hard disk radiator 20 to the outside air or other heat-conducting components, thereby reducing heat accumulation and temperature rise. The hard disk radiator 20 has a receiving space 22, and the hard disk module 10 is used to be installed in the receiving space 22. Generally speaking, the receiving space 22 has an opening, and the hard disk module 10 is inserted into the inside of the receiving space 22 through the opening, and can be pulled out of the receiving space 22 through the opening. The receiving space 22 is generally in a cubic shape, and the length direction of the receiving space 22 can be regarded as the insertion direction of the hard disk module 10, and the width direction and height direction of the receiving space 22 can be perpendicular to its length direction. When the hard disk module 10 is installed in the receiving space 22 of the hard disk radiator 20, the heat-conducting structure 12 and the side wall of the receiving space 22 abut each other, and the heat generated by the hard disk body 11 is transferred to the hard disk radiator 20 through the heat-conducting structure 12.

[0043] The hard disk module 10 includes a hard disk body 11 and two heat-conducting structures 12 respectively arranged on opposite sides of the hard disk body 11 in the width direction. The hard disk body 11 is the main functional component for storing video signals. The hard disk body 11 is generally in a cubic shape, the length direction of the hard disk body 11 is parallel to the length direction of the accommodation space 22, the width direction of the hard disk body 11 is parallel to the width direction of the accommodation space 22, and the height direction of the hard disk body 11 is parallel to the height direction of the accommodation space 22. The heat-conducting structure 12 is made of a material with good thermal conductivity, and the heat-conducting structure 12 can be compressed and deformed. After the hard disk body 11 is installed in the hard disk radiator 20, the heat-conducting structure 12 on one side of the hard disk body 11 abuts against one side wall of the accommodation space 22, and the heat-conducting structure 12 on the other side of the hard disk body 11 abuts against the other side wall of the accommodation space 22, so that the heat-conducting structures 12 on both sides are compressed, so that the heat transfer performance between the hard disk body 11 and the heat-conducting structure 12, and the heat transfer performance between the heat-conducting structure 12 and the hard disk radiator 20 are good, ensuring the heat transfer effect.

[0044] Specifically, see Figure 5 and Figure 6 The heat-conducting structure 12 includes a heat-conducting block 123, a first heat-conducting foam layer 121 and a second heat-conducting foam layer 122. The first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are respectively arranged on opposite sides of the heat-conducting block 123. The first heat-conducting foam layer 121 is in contact with the hard disk body 11 on the side facing away from the heat-conducting block 123, and the second heat-conducting foam layer 122 is in contact with the side wall of the accommodation space 22 on the side facing away from the heat-conducting block 123. The heat-conducting block 123 is block-shaped, and the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are both layered. The first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are respectively arranged on opposite sides of the heat-conducting block 123. It can be understood that the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are respectively arranged on opposite sides of the heat-conducting block 123 in the width direction, and the width direction of the heat-conducting block 123 is parallel to the width direction of the hard disk module 10. The first heat-conducting foam layer 121 is disposed adjacent to the hard disk body 11 and the two are in contact with each other, and the second heat-conducting foam layer 122 is disposed adjacent to the side wall of the accommodating space 22 and the two are in contact with each other. When the hard disk module 10 is assembled to the hard disk radiator 20, the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are compressed, so that the thermal contact between the heat-conducting block 123 and the hard disk body 11 is good, and the thermal contact between the heat-conducting block 123 and the hard disk radiator 20 is good. By arranging the heat-conducting foam layers on both sides of the heat-conducting block 123, after the heat-conducting foam layers are compressed, the heat dissipation channels of the hard disk body 11, the heat-conducting block 123 and the hard disk radiator 20 maintain good heat dissipation performance.

[0045] The first heat-conducting foam layer 121 is fixed to one side of the heat-conducting block 123, and the second heat-conducting foam layer 122 is fixed to the other side of the heat-conducting block 123. When assembling the hard disk module 10, the first heat-conducting foam layer 121 is first fixed to one side of the heat-conducting block 123, and then the second heat-conducting foam layer 122 is fixed to the other side of the heat-conducting block 123 to form the heat-conducting structure 12. Of course, the second heat-conducting foam layer 122 can also be fixed first, and then the first heat-conducting foam layer 121 can be fixed.

[0046] In the insertion direction of the hard disk module 10, the width of the hard disk body 11 is uniform, the thickness of the first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 is uniform, the width of the heat conductive block 123 gradually decreases, and the width of the accommodating space 11 also gradually decreases. The width direction of the heat conductive block 123 is parallel to the width direction of the hard disk module 10. The uniform thickness of the first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 means that the thickness is equal at any position of the thermally conductive foam layer. The first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 are both made of thermally conductive foam, and the thickness of the thermally conductive foam is fixed. By setting the thermally conductive block 123 with a variable width, the width of the heat conductive structure 12 can be gradually reduced in the insertion direction of the hard disk module 10, meeting the installation requirements of the hard disk module 10.

[0047] In the insertion direction of the hard disk module 10, the widths of the hard disk module 10 and the accommodation space 22 are gradually reduced. Accordingly, the hard disk module 10 is a wedge-shaped structure, and the accommodation space 22 is also a wedge-shaped structure. The hard disk module 10 and the accommodation space 22 match each other at least in the width direction. Then, when the hard disk module 10 is just inserted into the accommodation space 22, the distance between the two sides of the hard disk module 10 in the width direction and the side walls corresponding to the accommodation space 22 is large. As the hard disk module 10 is continuously inserted, the distance between the two gradually decreases. When the hard disk module 10 is about to be installed in place, the heat-conducting structures 12 on both sides of the hard disk module 10 in the width direction are respectively abutted and squeezed against the corresponding side walls of the accommodation space 22, generating assembly friction. Therefore, when the hard disk module 10 is installed, the friction force it is subjected to is small, which is convenient for installation, and there will be no large-scale extrusion damage to the heat-conducting structure 12.

[0048] The hard disk installation structure 100 in the above embodiment includes a hard disk module 10 and a hard disk radiator 20. The hard disk module 10 has a heat-conducting structure 12 on both sides. In the insertion direction of the hard disk radiator 20, the width of the heat-conducting block 123 and the width of the accommodation space 22 are gradually reduced. The width of the hard disk body 11 and the thickness of the heat-conducting foam layer are uniform, so that the width of the heat-conducting structure 12 is gradually reduced. In this way, when the hard disk module 10 is inserted into the accommodation space 22 of the hard disk radiator 20, only in the last stage of insertion, the heat-conducting structures 12 on both sides of the hard disk module 10 contact with the side walls of the accommodation space 22, and then squeeze the heat-conducting structure 12, so that the heat generated by the hard disk body 11 is transferred to the hard disk radiator 20 through the heat-conducting structure 12. In this way, the installation steps of the hard disk module 10 are simple, and the hard disk module 10 contacts the hard disk radiator 20 only in the last stage of inserting the hard disk module 10 into the accommodation space 22. The friction during the installation process is small and the heat-conducting structure 12 will not be damaged.

[0049] In some embodiments of the present invention, see Figure 5 The hard disk body 11 is a rectangular parallelepiped structure, and the heat-conducting structure 12 is a wedge-shaped structure. The central plane of the hard disk module 10 perpendicular to its width direction is a symmetry plane, and the hard disk module 10 is symmetrically arranged about the symmetry plane. In other words, the specific structure and shape of the two heat-conducting structures 12 are the same, and the inclination angles of the two heat-conducting structures 12 away from the hard disk body 11 are the same. In this way, the two heat-conducting structures 12 on both sides can be installed interchangeably.

[0050] In some embodiments of the present invention, see Figure 5 and Figure 6 The narrower end of the heat-conducting block 123 is the first end of the heat-conducting block 123, and the wider end of the heat-conducting block 123 is the second end of the heat-conducting block 123. The first end of the heat-conducting block 123 is located at the narrower end of the accommodating space 22, and the second end of the heat-conducting block 123 is located at the wider end of the accommodating space 22; the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are connected to each other at the first end of the heat-conducting block 123, and the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are respectively adhered and fixed on the opposite sides of the heat-conducting block 123.

[0051] The first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are connected to each other at the first end of the heat-conducting block 123, so that the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are an integrated structure, which is more convenient for assembling the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122. Since the first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are both adhered and fixed to the side of the heat-conducting block 123, the heat-conducting foam layer can be first fixed to one side of the heat-conducting block 123, then bypass the end of the heat-conducting block 123 to the other side of the heat-conducting block 123, and the remaining heat-conducting foam layer can be fixed to the other side of the heat-conducting block 123. In this way, the two heat-conducting foam layers can be assembled as one.

[0052] The first heat-conducting foam layer 121 and the second heat-conducting foam layer 122 are connected to each other at a first end of the heat-conducting block 123 , which can save the material of the heat-conducting foam and reduce the installation error of the heat-conducting foam layer.

[0053] In some embodiments, the first thermally conductive foam layer 121 has an adhesive backing and can be directly attached to a corresponding position of the thermally conductive block 123 .

[0054] In some embodiments, the second thermally conductive foam layer 122 has adhesive backing and can be directly attached to a corresponding position of the thermally conductive block 123 .

[0055] In other embodiments, the first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 are connected to each other at the second end of the heat conductive block 123 , and the area of ​​the connection is small, which can reduce the concentrated stress at the connection between the first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 .

[0056] In some embodiments of the present invention, the first thermally conductive foam layer 121 is fixed to the side wall of the hard disk body 11, and the second thermally conductive foam layer 122 is fixed to the side of the thermally conductive block 123 facing away from the hard disk body 11. The side of the thermally conductive block 123 facing the first thermally conductive foam layer 121 is pressed against the first thermally conductive foam layer 121.

[0057] In some embodiments of the present invention, the first heat-conducting foam layer 121 is fixed to the side wall of the hard disk body 11, and the second heat-conducting foam layer 122 is fixed to the inner side wall (the side wall of the accommodating space 22) of the hard disk heat sink 20. The side of the heat-conducting block 123 facing the first heat-conducting foam layer 121 is pressed against the first heat-conducting foam layer 121, and the side of the heat-conducting block 123 facing the second heat-conducting foam layer 122 is pressed against the second heat-conducting foam layer 122.

[0058] In some embodiments of the present invention, the first thermally conductive foam layer 121 is fixed to one side of the thermally conductive block 123, the second thermally conductive foam layer 122 is fixed to the inner wall of the hard disk heat sink 20, and the side of the thermally conductive block 123 facing the second thermally conductive foam layer 122 is squeezed against the second thermally conductive foam layer 122.

[0059] In some embodiments of the present invention, see Figure 4 , Fig. 9 and Fig.10The hard disk module 10 also includes a mounting bracket 13, which includes a mounting plate 131, a vertical plate 132 vertically connected to the mounting plate 131, and a connecting rib 133 vertically connected to the vertical plate 132. The hard disk body 11 is fixed to the mounting bracket 13, and the heat conductive block 123 has at least a first connecting position and a second connecting position. The heat conductive block 123 is rotatably connected to the mounting plate 131 and the connecting rib 133 at opposite sides of the first connecting position, and the heat conductive block 123 is detachably connected to the mounting plate 131 at the second connecting position through a connecting piece.

[0060] The heat conducting block 123 is connected to the mounting bracket 13, and the hard disk body 11 is fixed to the mounting bracket 13. The mounting bracket 13 is used to install the heat conducting block 123, the hard disk body 11, etc., so that the above components are connected to form the hard disk module 10, and the hard disk module 10 can be inserted into the interior of the accommodating space 22 as a whole. The heat conducting block 123 is rotatably connected to the mounting bracket 13 at a first connection position, and the heat conducting block 123 is detachably connected to the mounting plate 131 at a second connection position through a connecting piece 16. In other words, the connecting piece 16 can be removed, and the heat conducting block 123 is rotatably connected to the mounting bracket 13 only at one end, so that the heat conducting block 123 can rotate relative to the mounting bracket 13, thereby increasing the space between the two heat conducting blocks 123 and facilitating the placement of the hard disk body 11 between the two heat conducting blocks 123. Specifically, after fixing the first thermally conductive foam layer 121 and the second thermally conductive foam layer 122 to the thermally conductive block 123, the thermally conductive block 123 is rotated to increase the installation space, the hard disk body 11 is placed between the two thermally conductive blocks 123, and then the two thermally conductive blocks 123 are rotated to make the first thermally conductive foam layer 121 gradually approach the side of the hard disk body 11, and then the connecting piece 16 is locked so that the first thermally conductive foam layer 121 is squeezed by the hard disk body 11 and the thermally conductive block 123.

[0061] After the connector 16 is removed, the heat conducting block 123 can rotate relative to the mounting bracket 13 to increase the installation space of the hard disk body 11 , avoid contact between the hard disk body 11 and the first heat conducting foam layer 121 during installation, and reduce the difficulty of installing the hard disk body 11 .

[0062] By providing the mounting bracket 13, a mounting position can be provided for the hard disk body 11 and the heat conductive block 123, so that a hard disk module 10 is formed. The hard disk module 10 can be inserted into the accommodating space 22 as a whole, and the hard disk module 10 can be easily assembled and disassembled while ensuring the heat dissipation performance. After the heat conductive block 123 is disassembled from the mounting plate 131 at the second connection position, it can be rotated relative to the mounting bracket 13 to prevent the hard disk body 11 from contacting the first heat conductive foam layer 121 during installation.

[0063] In some embodiments of the present invention, see Fig. 9, the number of the first connection position is one, and the first connection position is located at the end of the heat conductive block 123 with a larger width, the number of the second connection positions is multiple, and the first connection position and the multiple second connection positions are sequentially spaced and distributed along the length direction of the heat conductive block. In other words, the wider end of the heat conductive block 123 is rotatably connected to the mounting bracket 13. The wider end of the heat conductive block 123 has enough space to set the rotating shaft or the shaft hole, which makes it easier to realize the rotatable connection between the heat conductive block 123 and the mounting bracket 13.

[0064] In some embodiments, see Fig. 9 and Fig.10 The connecting member 16 is a threaded member, the mounting plate 131 has a first connecting hole 1311, the heat conducting block 123 has a second connecting hole 124, and the threaded member passes through the first connecting hole 1311 and is connected to the second connecting hole 124. The threaded member connection method is easy to assemble and disassemble, and the connection is relatively stable.

[0065] In some embodiments, see Fig. 9 and Fig.10 The vertical plate 132 is vertically connected to the mounting plate 131, and the vertical plate 132 is also vertically connected to the connecting rib 133, so that the mounting plate 131 and the connecting rib 133 are arranged at intervals. One end of the heat conductor can be set between the mounting plate 131 and the connecting rib 133 through a rotating shaft, and the other parts of the heat conductor are connected to the mounting plate 131.

[0066] In some embodiments of the present invention, see Figure 5 , Figures 8 to 10 The mounting plate 131 has rail parts on both sides in the width direction, the rail parts protrude from the outer side of the heat-conducting structure 12, and the width of the rail parts gradually increases in the insertion direction of the hard disk module 10; the hard disk heat sink 20 has slide grooves 23 on two opposite side walls of the accommodation space 22, and the two rail parts are slidably arranged in the two slide grooves 23. The outer side of the heat-conducting structure 12 can be understood as the side of the heat-conducting structure 12 that faces away from the hard disk body 11. The mounting plate 131 has rail portions on both sides in the width direction, and the rail portions protrude from the outer side surfaces of the heat-conducting structure 12. It can be understood that the heat-conducting structure 12 is projected along the thickness direction of the mounting plate 131 to form a heat-conducting structure projection, and the width of the heat-conducting structure projection is smaller than the width of the mounting plate 131, and both sides of the width of the heat-conducting structure projection are within the area of ​​the mounting plate 131, so that both sides in the width direction of the mounting plate 131 protrude to form rail portions, and the rail portions can be respectively inserted into the corresponding slide grooves 23, and the opposite sides in the width direction of the mounting plate 131 cooperate with the two opposite slide grooves 23 of the accommodating space 22, which is equivalent to the cooperation between the rail and the slide groove 23, thereby forming a guide for the hard disk module 10.

[0067] The outer side surfaces of the heat-conducting structure 12 protrude from both sides of the mounting plate 131 in the width direction to form slide rail portions, so that the slide rail portions on both sides of the mounting plate 131 can cooperate with the slide grooves 23 of the accommodating space 22 to guide the insertion and withdrawal of the hard disk module 10, thereby making the installation of the hard disk module 10 smoother.

[0068] In some embodiments, see Figure 4 An insulating layer 134 is fixed to one side of the mounting plate 131 facing the hard disk body 11 to improve the insulation performance of the hard disk module 10. Optionally, the insulating layer 134 may be an insulating Mylar sheet.

[0069] In some embodiments of the present invention, see Figure 3 and Figure 4 The hard disk module 10 further includes a hard disk panel 14 and a handle structure 15. The hard disk panel 14 is fixedly connected to the mounting bracket 13, and the handle structure 15 is rotatably connected to the hard disk panel 14. After the hard disk module 10 is inserted into the accommodation space 22, the handle structure 15 is rotated to close it, which can further ensure that the hard disk module 10 is installed in place. When removing the hard disk module 10, the handle structure 15 can be rotated to open it, so that the user can hold the handle structure 15 to pull out the hard disk module 10.

[0070] In some embodiments of the present invention, see Figure 7 and Figure 8 The hard disk heat sink 20 includes two heat sink blocks 21 arranged at intervals, and a receiving space 22 for inserting the hard disk module 10 is formed between the two heat sink blocks 21. The number of receiving spaces 22 is multiple, and they are arranged in sequence along the thickness direction of the hard disk module 10, so that the hard disk heat sink 20 can stack multiple hard disk modules 10. The hard disk module 10 is located between the two heat sink blocks 21. The distance between the two heat sink blocks 21 is the width of the receiving space 22, which is compatible with the width of the hard disk module 10 (the distance between the outer sides of the two heat-conducting structures 12). The height of the receiving space 22 is at least twice the thickness of the hard disk module 10, so that at least two stacked hard disk modules 10 can be accommodated.

[0071] A plurality of hard disk modules 10 can be arranged inside a hard disk radiator 20 to fully utilize the internal space of the hard disk radiator 20 and expand the capacity of the hard disk recorder.

[0072] In some embodiments, there are multiple hard disk heat sinks 20 , and multiple hard disk modules 10 are stacked in each hard disk heat sink 20 .

[0073] In some embodiments, the hard disk heat sink 20 has a heat dissipation protrusion 24 on the side facing away from the accommodation space 22 to improve the heat dissipation performance of the hard disk heat sink. The heat dissipation protrusion 24 can be a heat sink, a heat dissipation convex point, a heat dissipation block, etc.

[0074] In some embodiments of the present invention, see Figure 5 and Figure 6 , the angle between the side of the heat-conducting structure 12 facing the accommodation space 22 and the insertion direction of the hard disk module 10 is A, and A is 1.5 degrees to 5 degrees. When the angle A is too large, the inclination angle of the side wall of the heat-conducting structure 12 is too large, which will lead to excessive occupation of the width direction space and increase the volume of the hard disk recorder; when the angle A is too small, the inclination angle of the side wall of the heat-conducting structure 12 is too small, and the hard disk module 10 is easy to collide and rub with the side wall of the accommodation space 22 during the installation process, affecting the assembly of the hard disk module 10.

[0075] In some embodiments, angle A is 2 degrees, 3 degrees, etc.

[0076] In some embodiments of the present invention, see Figure 7 The angle B between the side of the accommodation space 22 facing the hard disk module 10 and the insertion direction of the hard disk module 10 is 1.5 to 5 degrees. Angle A is equal to angle B, so that the hard disk module 10 and the accommodation space 22 match.

[0077] See also Figures 11 to 15 The present invention further provides a hard disk video recorder, which includes the hard disk installation structure 100 in any of the above embodiments. The hard disk video recorder also includes a chassis shell 200, a dust cover 300, a hard disk back plate 400 and a fan assembly 500. The hard disk radiator 20 is fixed in the chassis shell 200. The chassis shell 200 has an installation inlet connected to the accommodation space 22. The dust cover 300 is covered on the installation inlet. The hard disk module 10 is inserted into the accommodation space 22 from the installation inlet. The hard disk back plate 400 is arranged on the side of the chassis shell 200 that is away from the installation inlet. The fan assembly 500 is arranged on the side of the hard disk back plate 400 that is away from the hard disk module 10.

[0078] The chassis housing 200 is a shell-like structure having an inner cavity with an installation entrance. The hard disk module 10 and the hard disk heat sink 20 are both arranged in the inner cavity. The accommodating space 22 is a part of the inner cavity. The dust cover 300 is arranged at the installation entrance. When installing the hard disk recorder, the hard disk module 10 is first inserted into the accommodating space 22, then the handle structure 15 is closed, and finally the dust cover 300 is installed. The hard disk backplane 400 and the fan assembly 500 are both arranged at the back of the chassis housing 200, and the back of the chassis housing 200 is the side away from its installation entrance.

[0079] The hard disk video recorder provided by the present invention adopts the hard disk installation structure 100 mentioned above, and the hard disk installation structure 100 includes a hard disk module 10 and a hard disk radiator 20. The hard disk module 10 has a heat-conducting structure 12 on both sides, and in the insertion direction of the hard disk radiator 20, the width of the heat-conducting block 123 and the width of the accommodating space 22 are gradually reduced, and the width of the hard disk body 11 and the thickness of the heat-conducting foam layer are uniform, so that the width of the heat-conducting structure 12 is gradually reduced. In this way, when the hard disk module 10 is inserted into the accommodating space 22 of the hard disk radiator 20, only in the last stage of insertion, the heat-conducting structures 12 on both sides of the hard disk module 10 contact with the side walls of the accommodating space 22, and then squeeze the heat-conducting structure 12, so that the heat generated by the hard disk body 11 is transferred to the hard disk radiator 20 through the heat-conducting structure 12. In this way, the installation steps of the hard disk module 10 are simple, and the hard disk module 10 contacts the hard disk radiator 20 only in the last stage of inserting the hard disk module 10 into the accommodating space 22. The friction force during the installation process is small and the heat-conducting structure 12 will not be damaged.

[0080] In some embodiments of the present invention, dustproof foam is provided between the dustproof cover plate 300 and the mounting bracket 13, so as to improve the dustproof performance of the hard disk video recorder.

[0081] In some embodiments of the present invention, see Figures 13 to 15 The side of the chassis shell 200 away from the installation entrance is provided with a chassis vent 201 and a first heat dissipation port 202 that exposes the hard disk radiator 20, the hard disk back plate 400 blocks the chassis vent 201, and the hard disk back plate 400 is provided with a second heat dissipation port 401 that is directly opposite to the first heat dissipation port 202, and a first dustproof foam 600 is provided between the chassis shell 200 and the hard disk back plate 400; the first dustproof foam 600 includes a first surrounding portion 601 surrounding the chassis vent 201, and a second surrounding portion 602 surrounding the first heat dissipation port 202, the first surrounding portion 601 and the second surrounding portion 602 are connected to each other, and the space enclosed by the first surrounding portion 601 and the space enclosed by the second surrounding portion 602 are independent of each other.

[0082] The heat generated by the electronic components such as the hard disk module 10 can be dissipated through the chassis vent 201, the side wall of the chassis shell 200 away from the installation entrance (which can be called the rear side of the chassis shell 200), and the hard disk radiator 20. Through the arrangement of the chassis vent 201 and the first heat dissipation port 202, the heat can quickly enter between the hard disk back plate 400 and the rear side of the chassis shell 200. The first surrounding portion 601 of the first dustproof foam 600, the rear side of the chassis shell 200 (at the chassis vent 201), and the hard disk back plate 400 form a first closed space, so that the air flowing out of the chassis vent 201 can only be in the first closed space, and the outside space cannot enter the interior of the chassis shell 200 through the chassis vent 201. The second surrounding portion 602 of the first dustproof foam 600, the rear side of the chassis shell 200 and the hard disk backplane 400 form a second closed space, and air can only enter the second closed space from the second heat dissipation port 401, and the heat of the hard disk radiator 20 can enter the second closed space through the first heat dissipation port 202. Since the first closed space and the second closed space are independent of each other, air cannot enter the interior of the chassis shell 200, but the heat of the hard disk radiator 20 can be dissipated outwards without affecting its heat dissipation.

[0083] In some embodiments, the first dustproof foam 600 is adhered and fixed to the chassis housing 200 or the hard disk backplane 400 .

[0084] In some embodiments, the number of chassis vents 201 and first heat dissipation vents 202 are both plural and arranged alternately in sequence. Accordingly, the number of first surrounding portions 601 and second surrounding portions 602 are both plural and arranged alternately in sequence.

[0085] In some embodiments of the present invention, see Figures 12 to 15 The fan assembly 500 has an air outlet 501, and a second dustproof foam 700 is provided between the fan assembly 500 and the hard disk backplane 400. The second dustproof foam 700 has a third surrounding portion 701 surrounding the air outlet 501; the air outlet 501, the space enclosed by the third surrounding portion 701, the second heat dissipation port 401, the space enclosed by the second surrounding portion 602, and the first heat dissipation port 202 are arranged opposite to each other and are connected in sequence.

[0086] The third surrounding portion 701 of the second dustproof foam 700 and the hard disk backplane 400 form a third enclosed space (the space enclosed by the third surrounding portion 701 ). The gas exhausted by the fan assembly 500 enters the third enclosed space and the second enclosed space (the space enclosed by the second surrounding portion 602 ) from the air outlet 501 in sequence, passes through the first heat dissipation port 202 and contacts the hard disk radiator 20 , thereby quickly taking away the heat emitted by the hard disk radiator 20 .

[0087] In some embodiments, the second dustproof foam 700 is adhered and fixed to the fan assembly 500 or the hard disk backplane 400 .

[0088] In some embodiments, the second dustproof foam 700 further includes a fourth surrounding portion 702, which is disposed around the periphery of the fan assembly 500 to improve its sealing capability. The fourth surrounding portion 702 may be a closed annular structure or an annular structure with an opening.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
