Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 schematically illustrates an application scenario provided by an embodiment of the present application, as shown in fig. 1, the scenario includes a server, and the server may exemplarily include a server chassis, a server backplane disposed in the server chassis, and various functional devices disposed in the server backplane, and may further include a hard disk tray rack in which a hard disk is placed. The server back plate can be arranged in a partitioning mode, functional devices with different functions can be placed in each partition, and the hard disk tray frame and other functional devices can be located in different partitions.

In one example, the server in fig. 1 may be specifically designated as a 1U server, that is, the thickness of the server is 4.445 cm. For a 1U server, the functional devices disposed in the server backplane may generally include a Central Processing Unit (CPU), a memory, a motherboard, a power backplane, an input/output module, a hard disk module, and other functional devices, such as an interface circuit. And the hard disk module is usually arranged on one side close to the server backboard.

In the embodiment of the application, the internal space of the 1U server is usually smaller, and the accommodating space of the hard disk is also smaller. In a traditional server assembly scheme, a hard disk is placed in a server hard disk rack, then the hard disk is inserted into a hard disk plugging port, and then the hard disk and the hard disk rack are fixed. Specifically, the bottom of the hard disk is provided with a small hole, the server hard disk frame is also provided with small holes with equal sizes, a bolt is screwed in from one side of the hard disk frame until the bolt is screwed in the small hole of the hard disk, and the hard disk and the server hard disk frame are fixed by matching with a nut. However, in this fixing method, when the hard disk fails, the hard disk must be taken out for maintenance, that is, the server must be powered off, the bolt must be screwed out of the hard disk, the hard disk must be taken out, and then the hard disk must be fixed in the server again after the maintenance is completed. Obviously, the processing method may interrupt the processing process of the server, and after the server is restarted, the system restart and the data recovery are also required, which affects the performance of the server and consumes a lot of time cost.

In view of this, the present disclosure provides a hard disk fixing device, which can plug a hard disk into or out of a server without turning off a power supply of the server, and does not affect the normal operation of the entire server system. Namely, the hard disk fixing device provided by the embodiment of the application can realize the hot plug function of the hard disk of the server.

The following describes a specific structure of the hard disk fixing device disclosed in the present application by way of specific embodiments.

It should be understood that the hard disk fixing apparatus may be applied to the server illustrated in fig. 1, and may also be applied to other types of servers, where other types of servers may have more or fewer functional devices than those illustrated in fig. 1, and may also have other partition manners different from those illustrated in fig. 1, and this is not particularly limited in this embodiment of the present application.

Fig. 2 exemplarily shows a schematic structural diagram of a hard disk fixing device provided in an embodiment of the present application, where the hard disk fixing device is used to fix a hard disk on a server hard disk rack 200, a plug-in port 201 is provided on the server hard disk rack 200, and data is uploaded and downloaded by inserting the hard disk into the plug-in port 201 to establish a connection with a server. The hard disk fixing device shown in fig. 2 includes a tray 211 and a handle 212, wherein the tray 211 is used for carrying a hard disk, and the handle 212 is pivoted to two sides of the tray 211 and rotates between a horizontal position and a vertical position relative to the tray 211. The handle 212 is provided with a fulcrum 213, correspondingly, the server hard disk rack 200 is provided with a groove 202, and during the movement of the handle 212 relative to the tray 211 from the vertical position to the horizontal position, the fulcrum 213 slides in the groove 202 to drive the hard disk in the tray 211 to move towards the insertion opening 201 on the server hard disk rack 200 until the hard disk is inserted into the insertion opening 201.

In one possible implementation, during the movement of the handle 212 from the horizontal position to the vertical position relative to the tray 211, the fulcrum 213 slides in the groove 202 in the opposite direction, so as to move the hard disk in the tray 211 away from the insertion/extraction opening 201 on the server hard disk rack 200. As the handle 212 is rotated from the horizontal position to the vertical position with respect to the tray 211, the fulcrum 213 slides upward in the groove 202. At this time, the horizontal distance of the pivot point 213 relative to the pivot hole 214 on the handle 212 is increased, and the pivot point 213 is embedded in the groove 202 on the server hard disk rack 200, and the horizontal distance of the pivot hole 214 on the handle 212 relative to the groove 202 on the server hard disk rack 200 is not changed, so that the horizontal distance of the tray 211 relative to the groove 202 on the server hard disk rack 200 is increased, and the hard disk is driven to move away from the insertion/extraction opening 201 on the server hard disk rack 200 until the hard disk is pulled out of the insertion/extraction opening 201.

In the embodiment of the present application, the tray 211 is used for bearing a hard disk, in other words, the hard disk may be fixed on the tray 211, and the fixing manner may be, for example, an adhering fixing manner, or a screw fixing manner, or may also be other fixing manners, such as a rivet fixing manner, a snap fixing manner, or a welding fixing manner. It should be understood that any fixing manner capable of ensuring that the relative position between the tray 211 and the hard disk is not changed is within the protection scope of the embodiments of the present application, and the embodiments of the present application are not listed.

In the embodiment of the present application, the handle 212 may be any frame structure that can be pivoted to two sides of the tray 211, the shape of the frame structure may be, for example, a semi-circle, an ellipse, a polygon, a rectangle, a triangle, etc., and one or two ends of the frame structure are pivoted to the tray 211.

Fig. 3 schematically illustrates a structure of a hard disk fixing device according to an embodiment of the present application. As shown in fig. 3, the handle 212 may include a first support rod 2121, a second support rod 2122, and a cross rod 2123 connecting the first support rod 2121 and the second support rod 2122, wherein the first support rod 2121, the second support rod 2122, and the cross rod 2123 are fixedly connected to form a frame structure, and the first support rod 2121 and the second support rod 2122 are pivotally connected to opposite sides of the tray 211. Specifically, the first support rod 2121 may be pivoted to the C-side of the tray 211, and the second support rod 2122 may be pivoted to the D-side of the tray 211.

It should be noted that the cross bar 2123, the first support bar 2121 and the second support bar 2122 may be fixedly connected by welding or screws, or may be fixedly connected by other methods that enable relative positions to be unchanged, which is not specifically limited in this embodiment of the present invention.

Illustratively, referring to fig. 2, the shape of the support rod may be a structure with a long arm, and the end of the long arm is a polygon, and the polygon is pivotally connected with the tray. In this case, the handles 212 are pivotally connected to both sides of the tray 211, and are implemented as follows: the holes are formed in the positions, connected with the tray, of the supporting rods, the holes with the same size are formed in the corresponding positions of the side walls of the tray 211, and the bolts penetrate through the holes in the positions, connected with the tray, of the polygonal supporting rods and the holes in the side walls of the tray 211, so that the handle 212 can rotate around the bolts, and the rotating connection of the handle 212 and the tray 211 is achieved.

Illustratively, the rotatable angle range of the handle 212 may be limited to 0-90 degrees, i.e. it can only be rotated 90 degrees counterclockwise from the vertical direction or 90 degrees clockwise from the horizontal direction as shown in fig. 2, so as to avoid the technical problem of occupying much space in the server due to the excessive rotation angle of the handle 212.

As further illustrative, and with continued reference to fig. 2, a fulcrum 213 may also be provided on the handle 212. The fulcrum 213 may be specifically disposed at one side of the pivot hole 214 in the middle of the polygon, for example, when the hard disk fixing device can be horizontally placed, the handle 212 is in a vertical state, the fulcrum 213 is located in the horizontal direction of the pivot hole 214 in the middle of the polygon, and the distance from the pivot hole 214 in the middle of the polygon may be set according to actual requirements.

In the present embodiment, the shape of the fulcrum 213 may be varied, for example, in one example, the fulcrum 213 may be a small raised cylinder as illustrated in fig. 2, which is welded in the horizontal direction of the polygonal middle pivot hole 214. Thus, when the handle 212 rotates around the bolt from the vertical direction to the horizontal direction, the power transmission trajectory of the small cylinder is a 90-degree arc, and the center of the arc is the center of the pivot hole 214 in the middle of the polygon.

In an example, as shown in fig. 2, the server hard disk rack 200 may further have a groove 202, and the groove 202 may be disposed on a sidewall of the server hard disk rack 200. Specifically, fig. 4 is a schematic structural diagram illustrating a hard disk fixing device provided in an embodiment of the present application, and fig. 4(a) illustrates a state where a tray is just placed in a server hard disk rack; fig. 4 (B) shows a state of the tray after the hard disk is inserted into the insertion/extraction opening; fig. 4(C) shows a state in which the fulcrum is opposite to the server hard disk rack after the hard disk is inserted into the insertion/extraction port. As shown in fig. 4(a), when the tray 211 carrying the hard disk is placed in the hard disk rack of the server, the handle 212 on the tray 211 is perpendicular to the tray 211, and at this time, the fulcrum 213 on the handle 212 is embedded in the groove 202 and is located at an upper position in the groove 202. As the handle 212 is rotated relative to the tray 211 from the vertical position to the horizontal position, the fulcrum 213 slides downward in the groove 202. At this time, the horizontal distance of the pivot point 213 relative to the pivot hole 214 on the handle 212 is gradually decreased, and the pivot point 213 is embedded in the groove 202 on the server hard disk rack 200, that is, the horizontal distance of the pivot point 213 relative to the groove 202 on the server hard disk rack 200 is not changed, so that the horizontal distance of the pivot hole 214 on the handle 212 relative to the groove 202 on the server hard disk rack 200 is also decreased, that is, the horizontal distance of the tray 211 relative to the groove 202 on the server hard disk rack 200 is decreased, and thus the hard disk is driven to move towards the insertion/extraction opening 201 close to the server hard disk rack 200 until the hard disk is inserted into the insertion/extraction opening 201. As shown in fig. 4 (B), when the hard disk is completely inserted into the insertion/extraction opening 201 of the server hard disk rack 200 (for easy understanding, fig. 4 (B) shows a state where the hard disk is separated from the insertion/extraction opening 201, and fig. 4(C) shows a state where the hard disk is inserted into the insertion/extraction opening 201), the handle 212 is located in a horizontal position. At this time, as shown in fig. 4(C), the fulcrum 213 slides to the lowest position of the groove 202, and the fulcrum 213 is located right below the pivot hole 214 and has a horizontal distance of 0 from the pivot hole 214. In the process of pulling the hard disk out of the plug port 201, as shown in fig. 2, an upward pressure is applied to the handle 212, the fulcrum 213 slides upward in the groove 202, and the fulcrum 213 abuts against the B plane, which provides a supporting force for the fulcrum 213 to drive the pivot hole 214 to move away from the plug port 201 until the hard disk is pulled out of the plug port 201.

Therefore, the handles 212 are pivoted on the two sides of the tray 211, so that the handles 212 rotate between a horizontal position and a vertical position relative to the tray 211, and the hard disk can be inserted into or pulled out of the server hard disk frame 200, thereby realizing the hot plug function of the hard disk of the server. In an example, as shown in fig. 4(a) with continued reference, the groove 202 may be disposed at two sides of the server hard disk frame 200, so that a side plane of the groove 202 away from the insertion/extraction opening 201 (i.e., a plane a shown in fig. 4 (a)) may provide a supporting force for the fulcrum 213 during the sliding of the fulcrum 213 in the groove 202. Specifically, when the hard disk fixing device is horizontally placed, in the process of inserting the hard disk into the insertion opening 201, downward pressure is applied to the handle 212, the fulcrum 213 slides downward in the groove 202, meanwhile, the fulcrum 213 abuts against the plane a, the plane a provides a supporting force for the fulcrum 213, and the pivot hole 214 is driven to move towards the insertion opening 201 until the hard disk is inserted into the insertion opening 201.

In one example, and with continued reference to fig. 4(a), the recess 202 may be funnel-shaped, with the funnel body facing upward when the device is horizontally positioned. Thus, during vertical to horizontal rotation, the fulcrum 213 first enters the body of the hopper and moves along the body towards the lid, engaging the recess 202. The funnel-shaped groove 202 enables the supporting point 213 to be easily inserted into the groove 202, so that the hard disk can be more conveniently fixed.

It should be understood that in other examples, the groove 202 may have other shapes, such as a column or an inverted cone. Any groove 202 that can allow the fulcrum 213 to be inserted and provide a supporting force for the fulcrum 213 is within the scope of the embodiments, and the embodiments are not listed here.

As shown in fig. 3, the handle 212 may further include an elastic plug 2124, and the server hard disk rack 200 is correspondingly provided with a to-be-plugged hole 302 corresponding to the elastic plug 2124, and after the hard disk is plugged into the plugging port 201 of the server, the elastic plug of the handle 212 may be inserted into the to-be-plugged hole 302 to fix the hard disk in the server hard disk rack 200.

Illustratively, with continued reference to fig. 3, the resilient plug 2124 may be provided at the F-end of the crossbar and the standby jack 302 may be provided on the server hard disk rack 200. After the hard disk is inserted into the insertion/extraction port 201 of the server, the elastic plug 2124 of the handle 212 is inserted into the insertion/extraction hole 302 and is clamped. When the hard disk is removed, the elastic plug 2124 of the handle 212 may be ejected from the hole 302 to be inserted.

Specifically, as shown in fig. 4(C), when the hard disk fixing device is horizontally disposed, after the hard disk is inserted into the insertion/extraction opening 201, the handle 212 on the tray 211 is horizontally disposed with respect to the tray 211, and the elastic plug 2124 of the handle 212 is inserted into the insertion/extraction opening 302 and is locked. At this time, the fulcrum 213 on the handle 212 is located at a lower position in the recess 202. When the hard disk needs to be removed, a downward force is applied to the elastic plug 2124 to eject the elastic plug 2124 from the hole 302 to be inserted.

In one example, the server hard disk frame 200 may further be provided with a slide rail, the slide rail may be exemplarily provided on a side wall of the server hard disk frame 200, and correspondingly, the tray 211 may further be provided with a slide block corresponding to the slide rail, the side wall of the tray 211 is provided with the slide block, and a lubricant may be further applied on the slide rail or the slide block. Therefore, in the process that the handle rotates from the horizontal position to the vertical position, the sliding block slides leftwards along the sliding rail, so that the tray 211 can move towards the plugging port 201 close to the server hard disk rack 200 with the hard disk. On the contrary, in the process that the handle rotates from the vertical position to the horizontal position, the sliding block slides rightwards along the sliding rail, so that the tray 211 can move towards the plugging port 201 far away from the server hard disk rack 200 with the hard disk. By applying the lubricant, the friction force between the tray 211 and the server hard disk frame 200 can be reduced, so that the movement of the tray 211 relative to the server hard disk frame 200 is smoother, and the convenience of fixing the hard disk is improved.

In an example, the hard disk fixing device may further include a buffer 501, and fig. 5 exemplarily illustrates a structural schematic diagram of a cross section of a hard disk fixing device provided in an embodiment of the present application, as shown in fig. 5, the buffer 501 may have an i-shaped structure, and the tray 211 is clamped in a middle groove of the i-shaped structure. Specifically, the bottom of the tray 211 is provided with a downward groove, the bottom of the groove is provided with a small hole, and the middle upright post of the I-shaped structure passes through the small hole to clamp the tray 211 in the middle groove of the I-shaped structure.

Illustratively, the buffer 501 may be made of thermoplastic elastomer (TPE), which is a material combining plastic and rubber characteristics and shows high elasticity of rubber at normal temperature, and the buffer 501 has good buffering performance and is used at the bottom of the tray 211 to weaken vibration generated by server operation and protect the hard disk.

In one example, in order to make the effect of damping the vibration more remarkable, buffering members 501 may be further provided at four corners of each tray.

In one example, as shown with continued reference to fig. 5, the hard disk fixing device may further include a partition 502, and the partition 502 is fixed between the tray 211 and the server hard disk shelf 200. The spacer 502 may be disposed below the i-shaped cushion 501, and an upper surface of the spacer 502 is attached to a lower surface of the i-shaped cushion 501. Therefore, the vibration generated by the operation of the server can be further transmitted to the partition plate 502, so that the vibration transmitted to the hard disk is less, and the hard disk is prevented from being damaged.

In one example, the center of the buffer 501 and the partition 502 is provided with a hole, and the buffer 501 and the partition 502 are fixed on the tray 211 through the hole by a screw 503. For example, as shown in fig. 5, a through hole 504 may be formed in the middle of the buffer 501, and a screw 503 may be inserted into the through hole 504 of the buffer 501 through a hole in the partition 502. In this way, the bolts 503 pass through the openings in the partition 502, so that the partition 502 does not directly contact with the server hard disk rack 200, and the strength of the server vibration transmitted to the partition 502 can be effectively reduced.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the utility model.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
