[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0026] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0027] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 12 The embodiment of the present application discloses a hard disk bracket 100, which may include a bracket body 110 and an elastic gasket 120. The bracket body 110 is provided with a receiving space, which may be an open design for receiving a hard disk 200, and the hard disk 200 may be fixed in the receiving space of the bracket body 110 by means of clamping, bolting, etc.

[0029] The bracket body 110 may include two opposite side panels, which are necessary structures for enclosing the above-mentioned accommodation space, and elastic gaskets 120 are provided on the two opposite side panels of the bracket body 110, and at least part of the elastic gaskets 120 extends into the accommodation space.

[0030] When the hard disk 200 is placed in the accommodation space, the elastic gasket 120 can be in elastic contact with the hard disk 200, thereby providing an elastic buffering effect between the bracket body 110 and the hard disk 200. The elastic gaskets 120 can be distributed symmetrically or asymmetrically on the two side panels, and the specific number of the elastic gaskets 120 can be selected according to the specific sizes of the hard disk 200 and the bracket body 110. Exemplarily, two elastic gaskets 120 are respectively arranged on the two opposite side panels of the bracket body 110, and the elastic gaskets 120 on the two side panels are in elastic contact with the two opposite side surfaces of the hard disk 200 respectively. The elastic gasket 120 can be made of materials such as rubber and silicone, and the connection method between the elastic gasket 120 and the side panel can be bonding, clamping, etc. The shape of the elastic gasket 120 can be circular, elliptical, polygonal, etc.

[0031] From the above, it can be seen that the hard disk bracket 100 disclosed in the embodiment of the present application improves the relevant technology. Since the elastic gasket 120 can play a good buffering and protective role between the hard disk 200 and the bracket body 110, it can reduce the relative shaking between the hard disk 200 and the bracket body 110, thereby reducing the risk of bumping and damage to the hard disk 200 and improving the durability of the hard disk 200.

[0032] Furthermore, if Figures 1 to 3 As shown, the bracket body 110 may include a bottom plate 111, a first side plate 112, a second side plate 113 and a third side plate 114. The bottom edges of the first side plate 112, the second side plate 113 and the third side plate 114 are respectively connected to the first side edge, the second side edge and the third side edge of the bottom plate 111. The first side plate 112, the second side plate 113, the third side plate 114 and the bottom plate 111 together form the above-mentioned open accommodation space, which is convenient for the installation and fixation of the hard disk 200. The elastic gaskets 120 are respectively arranged on the first side plate 112 and the second side plate 113.

[0033] The first side panel 112 , the second side panel 113 , the third side panel 114 and the bottom panel 111 can be assembled by welding, bolting, riveting and the like. The first side panel 112 , the second side panel 113 , the third side panel 114 and the bottom panel 111 can also be manufactured in an integrated manner, which can further enhance the structural strength and consistency of the bracket body 110 .

[0034] It should be noted that the first side and the second side of the bottom plate 111 are two opposite sides of the bottom plate 111, and the first side and the second side are connected by a third side. A gap is reserved on the side of the bottom plate 111 opposite to the third side for the hard disk 200 to enter and exit the accommodation space.

[0035] In order to fix the elastic gasket 120, as Figures 1 to 3 As shown, mounting holes 115 can be provided on both the first side plate 112 and the second side plate 113, and the elastic gasket 120 can be arranged in the mounting holes 115 by interference fit, snap-fit, etc. to achieve assembly, and at least a portion of the elastic gasket 120 extends into the accommodation space. The profile of the mounting hole 115 matches the shape of the elastic gasket 120, and the number of the mounting holes 115 and the number of the elastic gasket 120 correspond to each other and are equal.

[0036] In an optional embodiment of the present application, Figure 4 As shown, the elastic gasket 120 can be assembled with the mounting hole 115 by snapping. Specifically, taking the circular elastic gasket 120 and the circular mounting hole 115 as an example, a groove body 121 is provided in the circumference of the elastic gasket 120, and the diameter of the mounting hole 115 is slightly smaller than the diameter of the elastic gasket 120. The edge of the mounting hole 115 can extend into the groove body 121 of the elastic gasket 120, so that the elastic gasket 120 is snapped into the mounting hole 115.

[0037] In addition, the elastic gasket 120 and the mounting hole 115 may be bonded together by coating an adhesive around the elastic gasket 120 or the mounting hole 115 .

[0038] To further enhance the buffering effect between the elastic gasket 120 and the side of the hard disk 200, as Figures 1 to 4 As shown, an elastic protrusion 122 can be provided on the surface of the elastic gasket 120 facing the accommodating space, and the elastic protrusion 122 can be one, two, or more than two. Since the elastic protrusion 122 can enhance more precise deformation control, the hard disk 200 can be smoothly installed in the bracket body 110 through the slight deformation of the elastic protrusion 122. At the same time, the elastic protrusion 122 can also ensure the buffering effect of the elastic gasket 120 between the hard disk 200 and the bracket body 110.

[0039] When the hard disk 200 is installed in the bracket body 110, the hard disk 200 needs to be placed in a specific position of the bracket body 110, such as Figure 1As shown, a positioning protrusion 1111 can be provided on the surface of the bottom plate 111 facing the accommodating space, and the hard disk 200 is provided with a hole that matches the positioning protrusion 1111, and the positioning protrusion 1111 extends into the hole of the hard disk 200 to achieve positioning. The number of the positioning protrusions 1111 and the number of the holes of the hard disk 200 are equal and one-to-one corresponding. For example, two positioning protrusions 1111 can be provided in the diagonal direction of the bottom plate 111, and two holes can be provided in the diagonal direction of the lower surface of the hard disk 200.

[0040] It should be added that, in order to achieve the positioning and cooperation between the hard disk 200 and the bracket body 110 , holes can be set on the bottom plate 111 of the bracket body 110 , and positioning protrusions 1111 can be set on the lower surface of the hard disk 200 .

[0041] In some optional embodiments, Figures 1 to 12 As shown, the hard disk bracket 100 may further include a first buckle plate 130 and a second buckle plate 140, wherein the first buckle plate 130 is buckled on the side of the first side plate 112 facing away from the accommodation space, and the second buckle plate 140 is buckled on the side of the second side plate 113 facing away from the accommodation space. The first buckle plate 130 and the second buckle plate 140 are both provided with a fixing column 141, and correspondingly, the first side plate 112 and the second side plate 113 are both provided with a first through hole 1131, and the elastic gasket 120 provided on the first side plate 112 and the second side plate 113 are both provided with a second through hole 123, and the fixing column 141 is provided in a one-to-one correspondence with the first through hole 1131 and the second through hole 123.

[0042] like Figures 5 to 10 As shown, when the first buckle plate 130 is buckled with the first side plate 112, and the second buckle plate 140 is buckled with the second side plate 113, the fixing column 141 is respectively penetrated through the first through hole 1131 and the second through hole 123, and is plugged into and matched with the plug hole 210 on the side of the hard disk 200, thereby further fixing the elastic gasket 120 and the hard disk 200 and avoiding relative movement between the elastic gasket 120 and the hard disk 200.

[0043] The first gusset plate 130 and the second gusset plate 140 can be connected to the bracket body 110 by means of clamping, bonding, bolting, etc. In order to improve the assembly efficiency, clamping is used as an example. Figure 1 to Figure 2As shown, first elastic buckles 142 can be provided on the side of the first buckle plate 130 and the side of the second buckle plate 140, and first snap holes 1132 can be provided on the first side plate 112 and the second side plate 113. The first elastic buckles 142 and the first snap holes 1132 are provided in a one-to-one correspondence. When the first buckle plate 130 is buckled with the first side plate 112 and the second buckle plate 140 is buckled with the second side plate 113, the first elastic buckle 142 and the first snap holes 1132 are elastically snapped, so that the first buckle plate 130 and the second buckle plate 140 are snapped to the bracket body 110. The first snap hole 1132 and the mounting hole 115 can be independent of each other or can be connected. In this embodiment, a snap hole is connected with the mounting hole 115, which can provide a larger installation space for the elastic gasket 120 and facilitate the installation of the elastic gasket 120.

[0044] In order to further improve the reliability of the connection between the first buckle plate 130 and the second buckle plate 140 and the bracket body 110, as shown in FIG. Figure 1 to Figure 2 As shown, a flange structure 1133 may be provided at both the edge of the first side plate 112 and the edge of the second side plate 113, the flange structure 1133 extends in a direction away from the accommodation space, the flange structure 1133 is provided with a second clamping hole 1134, and the edge of the first buckle plate 130 and the edge of the second buckle plate 140 are provided with a protruding clamping portion 143, and the clamping portion 143 is provided in a one-to-one correspondence with the second clamping hole 1134. When the first buckle plate 130 is buckled with the first side plate 112, and the second buckle plate 140 is buckled with the second side plate 113, the clamping portion 143 is clamped and matched with the second clamping hole 1134, so that the first buckle plate 130 and the second buckle plate 140 are clamped to the bracket body 110.

[0045] The housing of the electronic device is provided with structural parts for supporting the hard disk bracket 100 and the hard disk 200. The structural parts may include slide rails, brackets, etc. The hard disk bracket 100 may be assembled with the housing of the electronic device by sliding. When the hard disk bracket 100 and the hard disk 200 are installed in the housing of the electronic device, the hard disk bracket 100 needs to be in contact with the structural parts of the electronic device. In order to prevent the hard disk bracket 100 from falling out of the housing of the electronic device, an anti-falling-out structure may be provided on the hard disk bracket 100.

[0046] Specifically, Figure 1 to Figure 2As shown, an arc-shaped protrusion 1135 can be provided on the flange structure 1133 of the first side panel 112 and the second side panel 113, and the lower part of the arc-shaped protrusion 1135 is a hollow area, which can provide a certain deformation space for the arc-shaped protrusion 1135. When the hard disk bracket 100 and the hard disk 200 are installed into the shell of the electronic device, a certain thrust is applied to the hard disk bracket 100, and the arc-shaped protrusion 1135 abuts against the structural parts of the electronic device and deforms, so that the hard disk bracket 100 and the hard disk 200 can smoothly enter the shell and have stable contact with the structural parts of the electronic device. The hard disk bracket 100 is not easy to fall off from the shell, thereby improving the installation stability of the hard disk bracket 100 and the hard disk 200.

[0047] Since the housing of the electronic device needs to reserve an installation opening for the hard disk bracket 100, after the hard disk bracket 100 and the hard disk 200 enter the housing, the installation opening on the housing is exposed, and the hard disk bracket 100 and the hard disk 200 are easy to fall out of the installation opening, which also affects the aesthetics. Figure 1 to Figure 2 As shown, the hard disk bracket 100 can also include a door frame 150 and a rotating shaft 160. The door frame 150 is arranged opposite to the third side plate 114. The door frame 150 is provided with a shaft sleeve 151, and the third side plate 114 is provided with a shaft hole 1141. The rotating shaft 160 is respectively passed through the shaft sleeve 151 and the shaft hole 1141, so that the door frame 150 is hinged to the third side plate 114.

[0048] After the bracket body 110 enters the housing, the door frame 150 can be rotated to engage with the installation opening on the housing, and the door frame 150 can be set flush with the outer surface of the housing, further improving the aesthetics of the housing. When the hard disk 200 needs to be taken out, the door frame 150 can be separated from the installation opening on the housing by rotating, so that the bracket body 110 and the hard disk 200 can be taken out from the installation opening on the housing.

[0049] The door frame 150 and the support body 110 can be fixed by means of clamping, bolting, etc. Specifically, Figure 1 to Figure 2 , Figures 5 to 8 As shown, a slot 152 may be provided on the door frame 150, and a second elastic buckle 1142 may be provided on the third side plate 114 of the bracket body 110. The second elastic buckle 1142 and the slot 152 may be elastically engaged and matched, so that the door frame 150 may be engaged with the third side plate 114. In addition, a slot 152 may be provided on the third side plate 114 of the bracket body 110, and a second elastic buckle 1142 may be provided on the door frame 150, so that the elastic engagement and matching between the door frame 150 and the bracket body 110 may also be achieved.

[0050] In addition, in order to further enhance the protection effect of the door frame 150 on the bracket body 110 and the hard disk 200, as shown in FIG. Figure 1 to Figure 2 , Figures 5 to 8As shown, a protruding stopper 153 can be provided on the side of the shaft sleeve 151 of the door frame 150. The door frame 150 has a first position and a second position relative to the bracket body 110. When the door frame 150 is in the first position, the stopper 153 is engaged with the housing of the electronic device. The first position can correspond to the position where the door frame 150 is engaged with the third side plate 114 and is flush with the outer surface of the housing. At this time, under the engagement of the stopper 153 with the housing, the bracket body 110 is restricted from escaping from the housing. When the door frame 150 rotates to the second position, the stopper 153 is separated from the housing of the electronic device. The second position can correspond to the position where the door frame 150 is partially separated from the third side plate 114 and the door frame 150 is separated from the mounting opening on the housing. When in this position, the bracket body 110 can be taken out of the housing.

[0051] like Figure 1 to Figure 2 As shown, since the hard disk 200 generates heat during operation, in order to improve the heat dissipation performance of the hard disk 200, a hollow heat dissipation area 1112 can be set on the base plate 111. The shape of the hollow heat dissipation area 1112 can be circular, elliptical, polygonal, etc. The specific number of the hollow heat dissipation areas 1112 can be selected according to the size of the base plate 111.

[0052] In order to further improve the heat dissipation performance of the hard disk 200, Figure 1 to Figure 2 As shown, a first heat dissipation grille 1143 can also be provided on the third side panel 114, and a second heat dissipation grille 154 opposite to the first heat dissipation grille 1143 can be provided on the door frame 150. By providing the first heat dissipation grille 1143 and the second heat dissipation grille 154, the heat generated by the hard disk 200 can be quickly transferred to the outside of the shell.

[0053] The embodiment of the present application also discloses an electronic device, which may include a housing, a hard disk 200 and the hard disk bracket 100. The hard disk 200 is disposed in the accommodation space of the hard disk bracket 100. The hard disk bracket 100 may be slidably connected to the housing, and specifically, a bracket slide rail may be disposed inside the housing to support the hard disk bracket 100. The electronic device may include a computer host, a server, a portable personal computer, etc. Taking a computer host as an example, the housing of the electronic device may be a chassis, and a bracket slide rail may be disposed inside the chassis to support the hard disk bracket 100.

[0054] From the above description, it can be seen that the electronic device disclosed in the embodiment of the present application adopts the above-mentioned hard disk bracket 100. Since the elastic gasket 120 can play a good buffering and protective role between the hard disk 200 and the bracket body 110, it can reduce the relative shaking between the hard disk 200 and the bracket body 110, thereby reducing the risk of bumping and damage to the hard disk 200, and improving the durability of the hard disk 200 and the electronic device.

[0055] The above embodiments of the present application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0056] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
