Description

TECHNICAL FIELD

[0001] The utility model relates to a storage device field especially relates to a storage device. BACKGROUND

[0002] The storage device will produce heat in the use process, if the heat is not in time scattered, will cause the storage device to heat up constantly, make the storage device work in the high temperature environment, further influence the working condition of storage device. Figure 1 At present, the heat sink is usually used to accelerate the heat dissipation of the storage device, and the heat sink needs to be fixed.

[0003] As shown in Figure 1 The storage device includes: shell 110, PCB board 120, heat sink 130 and screw 140;PCB board 120 is located in the shell 110;The opposite two side walls of shell 110 have a plurality of up and down (height) extension and inside and outside through long hole 111;Heat sink 130 has corresponding number of threaded holes on the opposite two side walls, and heat sink 130 is inserted into shell 110 from the top of shell 110, and each threaded hole is opposite corresponding long hole 111;Screw 140 passes through long hole 111 and is screwed into corresponding threaded hole, thereby fixing heat sink 130 and shell 110.In the bottom of shell 110 and PCB board 120, heat dissipation pad can be arranged between PCB board 120 and heat sink 130, and the position of heat sink 130 can be adjusted up and down along the direction of long hole 111, so that heat sink 130 and PCB board 120 are pressed tightly and the heat dissipation pad and PCB board 120 and the bottom of shell 110 are pressed tightly.

[0004] The position of heat sink 130 needs to be adjusted left and right for several times to fix heat sink 130 and shell 110, so that each threaded hole of heat sink 130 is aligned with corresponding long hole 111 on shell 110 in left and right directions, so as to screw in screw 140.However, even if the threaded hole corresponds to the corresponding long hole 111, but in the process of screwing in screw 140, heat sink 130 also moves slightly, and the threaded hole and the corresponding long hole 111 will be misaligned, thereby increasing the difficulty of assembling and positioning heat sink 130, causing assembly inconvenience and screw 140 difficult to screw in and other problems, increasing the labor cost of assembly.

[0005] And, because the long hole 111 is arranged on the side wall of the shell 110, the positioning is relied on the screw 140 in the height direction of the shell 110, which leads to the uncertainty of the heat sink 130 in the height direction of the shell 110, thereby leading to the poor contact of the heat dissipation pad, and further affecting the heat dissipation of the storage device.

[0006] Therefore, how to simplify the assembly and positioning of the heat sink and the housing, thereby facilitating the assembly of the heat sink and the housing, and also avoiding poor contact of the heat dissipation pad, thereby improving the heat dissipation performance of the storage device, is a technical problem that urgently needs to be solved by those skilled in the art.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. Furthermore, spatial relationship terms such as "upper," "lower," "left," "right," "front," and "rear" are used for ease of description to explain the positional relationship between two components. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model and should not be construed as limiting it.

[0027] Please see Figure 2 The present invention provides a storage device, including: a housing 210 and a heat sink 230.

[0028] The radiator 230 is used for heat conduction and heat dissipation. It has one or more sliding buckles 231 protruding from the side walls on its two opposite side walls. Each sliding buckle 231 is used to snap into the groove 211 of the housing 210. At least one sliding buckle 231 is provided with a threaded hole 232 at a designated position for screwing in a screw 240.

[0029] Optionally, the heatsink 230 is generally rectangular, and its size is adapted to standard storage devices (e.g., M.2 standard storage devices, where M.2 is the physical dimensions and pin electrical interface specification for computer internal expansion cards and related connectors). Alternatively, the top of the heatsink 230 may have multiple downward-recessed grooves to increase the heat dissipation area of ​​the heatsink 230.

[0030] For ease of description, a rectangular coordinate system is established, such as... Figure 2 As shown. The width direction of the heat sink 230 is the X-axis direction; the length direction of the heat sink 230 is the Y-axis direction, and the X-axis and Y-axis directions define the orientation of the plane on which the heat sink 230 is located; the height direction of the heat sink 230 is the Z-axis direction, which is perpendicular to the plane on which the heat sink 230 is located. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0031] Alternatively, all sliding latches 231 on each sidewall parallel to the Y-axis are arranged in a horizontal row in the same direction as the Y-axis. Even more alternatively, each sidewall parallel to the Y-axis has two sliding latches 231, arranged in a horizontal row in the same direction as the Y-axis, and sequentially arranged along the Y-axis. For example, one sliding latch 231 is near the side of the heat sink 230 away from the Y-axis, and the other sliding latch 231 is near the other side of the heat sink 230 near the Y-axis.

[0032] Optionally, a threaded hole 232 is provided on one sidewall parallel to the Y-axis, extending along the X-axis direction, while the other sidewall parallel to the Y-axis does not have a threaded hole 232. This allows for a single screw 240 to securely connect the heat sink 230 to the housing 210, reducing the use of screws 240. Alternatively, the threaded hole 232 is located at a designated position on one of two sliding latches 231 on one sidewall. Still optional, the heat sink 230 is made of a thermally conductive material, such as aluminum.

[0033] Furthermore, to ensure that the sliding latch 231 is stably engaged within the groove 211 of the outer casing 210, the outer end of each sliding latch 231 can be bent upwards, that is, bent in the positive Z direction. This interference between the bent portion and the outer casing 210 prevents the sliding latch 231 from dislodging from the groove 211 in the Z direction. Alternatively, the outer end of each sliding latch 231 can be bent downwards, that is, bent in the negative Z direction. Again, interference between the bent portion and the outer casing 210 prevents the sliding latch 231 from dislodging from the groove 211 in the Z direction.

[0034] Continue reading Figure 2 The outer casing 210 has a base plate, and two opposing side plates extending from two opposite sides of the base plate parallel to the Y-axis toward the Z-axis. Each of these opposing side plates has one or more grooves 211, and each groove 211 has an L-shaped cross-section in the YZ plane. For example, the groove 211 has no notch at the top in the negative Y-axis direction, and the groove 211 has a notch at the top in the positive Y-axis direction. This notch is referred to as the mounting notch. During assembly, the sliding latch 231 of the radiator 230 extends into the groove 211 from the mounting notch, and then moves the radiator 230 in the negative Y-axis direction, causing the sliding latch 231 to slide in the negative Y-axis direction to the part of the groove 211 without the notch, and finally locks the sliding latch 231 into the part of the groove 211 without the notch.

[0035] Alternatively, the threaded hole 232 may be located at a designated position of the corresponding sliding latch 231 for ease of operation.

[0036] For example, in the YZ plane, the specified position needs to meet the following conditions: the angle between the line connecting the threaded hole 232 and the corresponding sliding buckle 231 and the Y-axis is the same as the angle between the hypotenuse of the L-shaped groove 211 and the Y-axis; and the distance between the threaded hole 232 and the corresponding sliding buckle 231 must be such that after the sliding buckle 231 is engaged in the corresponding groove 211, and after the screw 240 is screwed into the threaded hole 232, the screw 240 must be engaged at the top of the L-shaped groove 211 in the Z-axis direction.

[0037] Optionally, the housing 210 is generally rectangular. Also optionally, the storage device includes a PCB board 220; the width (X-axis direction) of the housing 210 is slightly larger than the width (X-axis direction) of the PCB board 220, so that the PCB board 220 can be placed inside the housing 210. Still optionally, all the grooves 211 on each side plate parallel to the Y-axis are arranged in a horizontal row in the same direction as the Y-axis. Still optionally, each side plate parallel to the Y-axis has two grooves 211, and the two grooves 211 are arranged in a horizontal row in the same direction as the Y-axis.

[0038] Optionally, a groove 211 on one side plate parallel to the Y-axis has a mating opening at its top in the Z-axis direction. This mating opening is formed by a rearward recess at the top of the groove 211 in the Z-axis direction, providing more assembly space for the screw 240 to mate with the threaded hole 232. The groove 211 on the other side plate parallel to the Y-axis does not have a mating opening to accommodate a single screw 240. Alternatively, the mating opening is located near the top of the groove 211 for ease of operation. Alternatively, the rear groove 211 of the two grooves 211 has a mating opening. Again, the housing 210 is optionally made of metal, such as stainless steel. Alternatively, the housing 210 is a stamped part.

[0039] Based on the above, a limiting wall 212 is provided extending from one side of the bottom plate of the outer casing 210 parallel to the X-axis toward the Z-axis, and the width of the limiting wall 212 is no greater than the width between the two side plates parallel to the Y-axis; the limiting wall 212 is parallel to the X-axis, and the height of the limiting wall 212 is lower than the height of the two side plates, for example, the height of the limiting wall 212 is the same as the height of the PCB board 220, thereby blocking the PCB board 220 by the limiting wall 212. Optionally, the limiting wall 212 is far away from the two side plates and has a specified distance between it and the two side plates, thereby preventing the sliding buckle 231 from driving the PCB board 220 forward during the sliding process in the slide groove 211.

[0040] Alternatively, the threaded hole 232 may be located at a designated position of one of the two sliding latches 231 on a side wall, on the side of the sliding latch 231 away from the limiting wall 212.

[0041] Alternatively, the storage device also includes a thermal pad 250. The thermal pad 250 and the PCB board 220 are stacked inside the housing 210. Various components and chips are disposed on the PCB board 220. The sliding clip 231 of the heat sink 230 is engaged with the unnotched part of the slide groove 211 of the housing 210. The screw 240 is screwed into the threaded hole 232 of the heat sink 230 and is engaged with the part of the slide groove 211 with the mounting notch.

[0042] Optionally, screw 240 is engaged with the mating opening of slide groove 211. Also optionally, thermal pad 250 includes: thermal pad 251 and thermal pad 252; thermal pad 252 is placed between the upper surface of PCB board 220 and heat sink 230 to conduct heat from PCB board 220 to heat sink 230; thermal pad 251 is placed between the lower surface of PCB board 220 and the base plate of housing 210 to conduct heat from PCB board 220 to housing 210. Still optionally, thermal pads 251 and 252 are both rectangular. Again optionally, thermal pad 250 is made of insulating thermally conductive material. For example, thermal pads 251 and 252 are disposed at the chip location on PCB board 220 to conduct heat generated by chip operation to heat sink 230 and housing 210.

[0043] The following describes the assembly process of the storage device of this utility model. First, during the assembly process, the exploded view ( Figure 2 The components are assembled sequentially to obtain the following: Figure 3A The initial assembly diagram is shown. Specifically, the thermal pad 251 is fixed (e.g., glued) to a designated position on the base plate of the housing 210, the PCB board 220 is placed on the thermal pad 251, the thermal pad 252 is placed on the PCB board 220, and then the heat sink 230 is placed on the thermal pad 252. At the same time as the heat sink 230 is placed, the sliding clip 231 of the heat sink 230 is inserted into the slide groove 211 from the mounting notch 211.

[0044] Assemble the components as follows: Figure 3A After reaching the desired state, the sliding latch 231 will be placed into the slot 211, and then the heat sink 230 will be pushed forward (in the negative direction of the Y-axis). The sliding latch 231 will slide from the rear part of the slot 211 to the front part of the slot 211 (e.g., Figure 3B (As shown in the figure), screw 240 into the threaded hole 232 of the heat sink 230, and lock the head of the screw 240 into the mating opening of the rear part of the slide groove 211, thereby locking the heat sink 230 in place by screw 240 and preventing the heat sink 230 from moving in the Y-axis direction.

[0045] This utility model utilizes a sliding groove in a sliding buckle to limit the assembly, which restricts the position in the X and Z axis directions. Then, it is locked with screws in the Y axis direction to prevent backward movement in the Y axis direction, thereby saving screws, reducing assembly time, and improving assembly convenience. Furthermore, since the outer shell is a stamped part, the processing accuracy of the stamping cut surface is also utilized to improve the assembly accuracy of the storage device.
