The hard disk module provided by the present invention includes the following parts: a hard disk body 3 and a hard disk frame 2. A plurality of hard disk bodies 3 are stacked and inserted into the hard disk frame 2. One end of the hard disk frame 2 is fixed to the chassis bottom plate 10 through a rotating shaft. One end and the other end can be rotated around the rotation axis. The second end can be referred to as FIG. 1. The left end of the hard disk frame 2 is referred to as the first end, and a segment of the hard disk frame 2 is referred to as the second end. The hard disk frame 2 is further provided with a rotatable lifting component 6. The hard disk module further includes a fixing bracket 4. The fixing bracket 4 is provided on at least one side of the hard disk frame 2, and may also be provided on both sides. The fixing bracket 4 is provided with an overlapping groove 41 that cooperates with the pulling component 6.

When the hard disk body 3 needs to be hot-plugged for maintenance. Simply lift the lifting component 6 so that the second end is lifted and rotated a certain angle around the first end, and the lifting component 6 is rotated to cooperate with the overlap groove 41 to keep the angle fixed. At this time, hot-plug maintenance can be performed on the hard disk body 3. A certain angle here is to satisfy that all the hard disk bodies 3 can be pulled out from the hard disk frame 2.

By providing the first end and the second end of the hard disk module provided by the present invention, the hard disk module can be rotated around the first end as an axis to fit all the hard disk bodies 3 to be taken out of the hard disk frame 2 to facilitate the heating of the hard disk body 3. Insertion and maintenance, compared with the traditional hard disk body 3 with limited installation space, which is inconvenient to take out from the hard disk module at both ends is fixed, which greatly improves the maintainability of the hard disk body 3. At the same time, because the rotating hard disk frame 2 is used, the hard disk body 3 can be hot-plugged and maintained without leaving a horizontal plug-in space for the hard disk body 3, and a small distance between the hard disk modules or between the hard disk modules and other components is achieved. Installation reduces the installation space of the hard disk module. The traditional hard disk module that meets the 3 hot-swappable hard disk body has high requirements on the layout of the chassis. It is necessary to leave enough space for the hard disk body 3 to be plugged in. For different types of chassis, such requirements are difficult to achieve, resulting in traditional The universality of the hard disk module for hot-plugging the hard disk body 3 is poor. The hard disk module provided by the present invention has a small requirement for installation space, and can be used universally as long as a small space is left for different models with different layouts, and the versatility of the hard disk module capable of realizing hot plugging of the hard disk body 3 is improved. .

The hard disk module provided by the present invention will be described in more detail below with reference to the drawings and specific embodiments.

First specific embodiment: As shown in FIG. 1, the hard disk module includes a hard disk body 3 and a hard disk frame 2. A plurality of hard disk bodies 3 are stacked and connected to the hard disk frame 2, and a sliding slot 22 is specially provided to facilitate the hard disk body 3 from When the hard disk frame 2 is inserted and pulled, a plurality of sliding grooves 22 are arranged in a vertical direction of the hard disk frame 2, and a single sliding groove 22 extends in a horizontal direction. The hard disk frame 2 has a fixing portion 1 connected by a rotating shaft at one end. The fixing portion 1 includes a fixing piece 101. The hard disk frame 2 has a rotating plate 21 at the bottom. The end is a shaft rotation. The fixing piece 101 is provided with a plurality of holes, and is fixed to the chassis bottom plate 10 by an anchor screw 102. The fixing piece 101 can also be directly welded to the chassis bottom plate 10, and the fixing screw 102 is more convenient for disassembly and has strong flexibility. One end of the hard disk frame 2 connected through the shaft and the fixing piece 101 is called a first end, as shown in the left end in FIG. 1; the other end of the hard disk frame 2 is called a second end, as shown in the right end in FIG. 1; the second end Can rotate around the first end.

The hard disk frame 2 is equipped with a lifting component 6 near the second end, and the lifting component 6 is installed near the second end. The main purpose is to pull and save labor. Here, it is specifically a U-shaped handle installed upside down. It can also be other shapes, even It can be a lifting ring, in short, it can meet the lifting requirements. The lifting component 6 and the side wall of the hard disk frame 2 are connected by a rotating member 8 to realize the rotation of the lifting component 6. Here, the rotating member 8 is specifically a screw. The side wall of the hard disk frame 2 and the two ends of the pulling assembly 6 are provided with holes for the rotating member 8 to pass through. The two are rotatably connected through the holes and the rotating member 8 to cooperate. The opening of the lifting component 6 is opened in the middle of the handles on both sides of the lifting component 6. The lower part of the rotating member 8 is also provided with a limiting portion 9. The two sides of the hard disk frame 2 are fixed to the top of the fixing bracket 4 of the chassis. An overlap groove 41 is provided. It is convenient to rotate the hard disk frame 2 to support the hard disk frame 2 in cooperation with the limiting portion 9 when the second end is pulled to a certain height. The fixing bracket 4 is also provided with a fixing groove 43 for cooperating with the limiting portion 9 to restrict the movement of the hard disk frame 2. The fixing groove 43 and the overlapping groove 41 communicate with each other through the leading edge 42 of the edge of the fixing bracket 4. The overlapping groove 41 is closer to the first end than the fixing groove 43, and the leading edge 42 is along the first end to the The direction of the second end gradually decreases. The limiting portion 9 is specifically a metal protrusion provided integrally with the lifting component 6, and may also be a bolt connected to the lifting component 6 by welding or other means. The position of the overlap groove 41 is sufficient to move the limiting portion 9 to overlap. In the slot 41, all the hard disk bodies 3 can be smoothly taken out from the hard disk frame 2.

The structure that restricts the movement of the hard disk frame includes a limiting portion 9 and a fixing groove 43. The fixing groove 43 is closer to the second end than the overlapping groove 41 and is located below the overlapping groove 41. The lower part here refers to the lower side closer to the second end. The details are shown in the lower right of Figure 1. Between the overlapping groove 41 and the fixing groove 43 is a guide edge of the fixing bracket 4 that can be slid by the limiting portion 9. The fixing groove 43 includes a locking end 431 for engaging the limiting portion, and further includes a moving-out end 432 communicating with the locking end 431 in the length direction of the hard disk frame; a slot 433 of the fixing groove 43 is located on the moving-out end. Above 432, and the locking end 431 communicates with the moving end 432. The fixing groove 43 has a structure in which the notch 433 is smaller than the width of the groove and the notch 433 of the fixing groove 43 is close to the second end; the width of the notch 433 is slightly larger than the width of the limiting portion 9 so that the limiting portion 9 can be easily removed from the fixing groove 43 to the end 432 Remove and place. Rotate the pull-up assembly 6 to make the stop 9 away from the notch 433 to the locking end 431. The fixing groove 43 cooperates with the stop 9 to fix the second end of the hard disk frame 2. Turn the pull-up assembly 6 to make the stop The part 9 reaches the notch 433 and lifts the pulling component 6 to lift the limiting part 9 from the notch 433 of the fixing groove 43 and slides along the frame of the fixing bracket 4 to the overlapping groove 41 to place. The overlapping groove 41 supports the hard disk frame 2 through the position-limiting portion 9 and the lifting component 6 so that the hard disk body 3 can be taken out obliquely upward from the hard disk frame 2.

The elastic portion 7 specifically includes an elastic member mounting hole, an elastic member, and a fixed terminal. The elastic member is specifically a spring. An elastic member mounting hole is opened above the rotating member 8 and is provided on a corresponding side wall of the fixed bracket 4 near the second end. One fixed terminal is located near the second end with respect to the pull-up assembly 6. One end of the elastic member is fixed to the fixed terminal, and the other end is fixed to the elastic-member mounting hole of the pull-up assembly 6. In this way, under the action of the tensile force of the elastic component, the lifting component 6 can realize the rotation of the first end axis (defined as a positive rotation, as shown in the clockwise direction shown in FIG. 1), and the limit portion 9 moves to The fixing groove 43 is locked at the end 431 to fix the second end of the hard disk frame 2. When the hard disk frame 2 needs to be rotated, turn the lifting component 6 in the opposite direction to take out the limiting portion 9 from the slot 43 of the fixing groove 43 and rotate and pull the second end to place the limiting portion 9 in the overlap groove 41 to support the hard disk frame 2. can. Other elastic components can also be used instead of the spring. The elastic components can even be torsion springs, rubber bands, etc., which can meet the elasticity of the retaining position 9 and the locking end 43 of the fixing groove 43 to cooperate with each other to achieve fixing. The second end of the hard disk frame 2.

In particular, a stop 5 is provided on the side of the hard disk frame 2 far from the second end, specifically in the direction of reverse rotation (specifically, the counterclockwise direction of FIG. 1) relative to the pull assembly 6, which may be specifically provided on the hard disk. The metal protrusions on the side wall of the frame 2 are used to limit the rotation angle of the lifting component 6 and prevent the elastic component from being damaged when the angle of the rotating lifting component 6 is too large when the second end is pulled. That is, when the lifting component 6 rotates in the reverse direction to contact the stopper portion 5, the hard disk frame 2 is lifted by the interaction with the stopper portion 5 instead of the pulling force of the elastic member.

For high storage density servers, one hard disk module usually cannot meet the requirements, and often multiple hard disk modules need to be installed to achieve the storage function. The installation positions of multiple hard disk modules are shown in Figure 2. The connected hard disk modules or hard disk modules and other components can be arranged in a tightly arranged manner to save chassis space.

As shown in FIG. 3, during normal operation, a plurality of hard disk bodies 3 are inserted and stacked in the hard disk frame 2. The first end of the hard disk frame 2 is fixed to the chassis bottom plate 10 through the fixing piece 101; under the action of the elastic component, the position-limiting portion 9 is kept away from the fixing groove 43 slot 433 by the lever principle, and is fixed in the fixing groove 43 to fix the hard disk frame 2 the second end. When hot-plugging maintenance of the hard disk body 3 is required, turn the lifting component 6 in the reverse direction to take out the limiting portion 9 from the slot 43 of the fixing groove 43; lift the lifting component 6 to touch the stopper portion 5 to pull the hard disk frame 2 The second end rotates around the first end, and the limiting portion 9 moves along the guide edge 42 of the fixing bracket between the overlapping groove 41 and the fixing groove 43 and is placed in the overlapping groove 41. At this time, the hard disk frame 2 is inserted into the hard disk body The opening of 3 is obliquely upward, so that the hard disk body 3 can be hot-plugged and maintained conveniently.

The hard disk module provided in this embodiment includes a hard disk frame 2 and a hard disk body 3; the hard disk frame 2 is provided with a first end and a second end, and the second end is rotated by the pull-up assembly 6 and the limiting portion 9 is placed in the overlap groove 41 It is that the opening of the hard disk frame 2 connected to the hard disk body 3 is inclined upward, which is convenient for the hard disk body 3 to perform hot plugging maintenance. By pulling out the hard disk body 3 obliquely upward, the reserved space between the hard disk modules and between the hard disk modules and other components is greatly reduced. Compared with the traditional hard disk module, the hard disk body 3 is horizontally plugged and unplugged and requires a large installation space, which greatly reduces the space required for installing the hard disk module. At the same time, due to the small installation space, this hard disk module does not have high requirements on the layout of the chassis, and it has strong versatility for different specifications and models of the chassis.

By setting the fixing groove 43 and the limiting portion 9 of the lifting assembly 6, the second end is fixed or unsecured and rotated according to the working state; the elastic member can be set to pull the lifting assembly by the elastic force in the normal working state of the hard disk body 3. The limiting portion 9 of 6 to the locking end 431 of the fixing groove 43 away from the notch 433 fix the hard disk frame 2 and the hard disk body 3. Prevent the elastic module from rotating and shaking during transportation or moving the chassis to damage the hard disk body 3. At the same time, a stopper 5 is provided on the side wall of the hard disk frame 2 in the reverse rotation direction of the pull-up assembly 6 to limit the rotation angle of the pull-up assembly 6 and prevent the elasticity of the pull-up assembly 6 from being too large to damage the elastic component.

The specific structure of the adjusting portion is shown in FIG. 4, and includes a fixing bracket 4, an adjusting plate 11 connected to the fixing bracket 4 through a guide groove, and an overlapping groove 41 on the adjusting plate 11. The adjusting plate 11 and the fixing bracket 4 are each provided with a plurality of height adjusting holes 12 as shown in FIG. 4. Bolts are used to fix the adjusting plate 11 and the fixing bracket 4 through the holes to adjust the height of the overlapping groove 41. The hard disk frame 2 is rotated by an appropriate angle and overlapped with the overlapping groove 41 so that all the hard disk bodies 3 can be taken out from the second end of the hard disk frame 2.

Compared with the first embodiment, the second specific embodiment with an adjustment section is implemented to adjust the height of the overlap groove 41, so that in special circumstances, including changes in the layout of the chassis, the height can be adjusted by The restriction portion 9 of the lifting assembly 6 and the overlap groove 41 are matched to realize that all the hard disk bodies 3 can be pulled out from the hard disk frame 2, which further improves the versatility of the hard disk module. Of course, the height adjustment here also changes the rotation angle. Limited by the stopper 5.
