Description
Technical Field
The invention relates to the technical field of server sliding rails, in particular to a sliding rail and a blade type server.
Background
The chassis of the server is often connected with the cabinet through the sliding rail, so that the installation position is determined through the limiting and sliding of the sliding rail, and meanwhile, the installation and the use of the chassis are convenient. As the application of server technology has matured, the computing power and density of the server have increased, and the volume and weight of the server have increased, so the bearing of the sliding rail has also increased.
The slide rails are generally mounted on both sides of the chassis in the length direction or the width direction. At present, the chassis of a server commonly used in the market is placed along a horizontal direction (i.e. the length direction and the width direction of the chassis are parallel to a plane in the horizontal direction), so that the gravity direction of the chassis is parallel to the mounting surface (vertical plane) of the sliding rail on the chassis, and the bearing of the sliding rail on the chassis is small.
However, for the blade server, the chassis is generally vertically installed on the cabinet (i.e., the length direction and the width direction of the chassis are parallel to the plane in the vertical direction), so that the sliding rail is located on the upper side and the lower side of the chassis, the gravity direction of the chassis is perpendicular to the installation surface (the horizontal plane) of the sliding rail on the cabinet, and almost all the gravity of the chassis is transferred to the installation surface through the sliding rail, so that the bearing of the sliding rail is larger, and the problems of shortening the service life of the sliding rail, reducing the strength, increasing the failure rate and the like are caused.
Disclosure of Invention
Based on this, it is necessary to provide a slide rail and a blade server aiming at the technical problems of short service life, reduced strength and increased failure rate of the slide rail caused by larger bearing of the slide rail between the chassis and the cabinet of the blade server in the prior art.

In one embodiment, the slide rail further comprises:
an outer stop portion disposed on the outer rail;

a deflector rod positioned between the inner rail and the outer rail, and
The deflector rod is connected with the inner rail through the elastic piece, and the deflector rod can be allowed to reciprocate along the first direction through elastic deformation of the elastic piece, so that the deflector rod can drive the rotating piece to switch between the first angle and the second angle;

Referring to fig. 1 and 2, an embodiment of the present application provides a sliding rail for use in a blade server (not shown). The track includes an outer rail 110, an inner rail 120, and a plurality of rolling elements 130. The first direction XX ', the second direction YY ', and the third direction ZZ ' are used for convenience of description. When the slide rail is actually applied to the blade server, the first direction XX ' and the second direction YY ' are respectively along the horizontal direction, and the third direction ZZ ' is along the vertical direction. The first direction XX ', the second direction YY ' and the third direction ZZ ' are perpendicular to each other.
The outer rail 110 includes a bottom wall 111 and two side walls 112 that are connected. The two side walls 112 and the bottom wall 111 enclose a recess 113 recessed in a third direction ZZ'. The outer rail 110 is used to connect with the cabinet of the blade server. The inner rail 120 is in moving engagement with the groove 113 in the first direction XX'. The inner rail 120 has an inner surface 121 opposite the bottom wall 111. The inner rail 120 is used to connect with an end of a chassis of the blade server in a vertical direction. The rolling member 130 is located between the inner surface 121 and the bottom wall 111, and the inner surface 121 and the bottom wall 111 are respectively in rolling engagement with the rolling member 130.
When the slide rail is used in a blade server (not shown), the chassis is vertically mounted on the cabinet. At least the lower end of the cabinet is connected with the cabinet in a sliding way along the first direction XX' through a corresponding sliding rail. The lower end of the chassis is connected with the inner rail 120 of the corresponding slide rail, and the outer rail 110 of the slide rail is connected with the cabinet, so that the mounting surface of the outer rail 110 of the slide rail on the cabinet is an (upward) horizontal plane. Since the rolling members 130 are located between the inner surface 121 and the bottom wall 111, the gravity of the chassis can be transferred to the mounting surface of the outer rail 110 on the cabinet via the inner rail 120, the rolling members 130, and the bottom wall 111 in sequence in the vertical direction. Therefore, the rolling element 130 can effectively bear most of gravity of the chassis, so that the risk of failure of the sliding rail is reduced, and the service life and strength of the sliding rail are prolonged. Meanwhile, since the inner surface 121 and the bottom wall 111 are respectively in rolling engagement with the rolling members 130, resistance when the inner rail 120 moves along the first direction XX' relative to the outer rail 110 can be effectively reduced, so that the cabinet can be smoothly inserted into or pulled out of the cabinet.
It will be appreciated that the upper end of the chassis may also be slidably connected to the cabinet along the first direction XX' by a corresponding slide rail, and the upper end of the chassis is connected to the inner rail 120 of the corresponding slide rail, and the outer rail 110 of the slide rail is connected to the cabinet, so that the mounting surface of the outer rail 110 of the slide rail on the cabinet is a (downward) horizontal plane.
Referring to fig. 2, in an embodiment, a first limiting groove 122 extending along a first direction XX 'is formed on the inner surface 121, and the first limiting groove 122 is in limiting fit with the rolling element 130 to limit the position of the rolling element 130 along a second direction YY'. The bottom wall 111 is formed with a second limiting groove 114 extending in the first direction XX ', and the second limiting groove 114 is in limiting fit with the rolling element 130 to limit the position of the rolling element 130 along the second direction YY'.
Since the first limiting groove 122 defines the position of the rolling element 130 along the second direction YY ', the rolling element 130 can roll along the first direction XX ' between the inner surface 121 and the bottom wall 111, and smooth and stable movement of the inner rail 120 along the first direction XX ' relative to the outer rail 110 is facilitated. Similarly, since the second limiting groove 114 defines the position of the rolling element 130 along the second direction YY ', the rolling element 130 can be further ensured to roll along the first direction XX ' between the inner surface 121 and the bottom wall 111, and smooth and stable movement of the inner rail 120 along the first direction XX ' relative to the outer rail 110 is facilitated.
Referring to fig. 2, in one embodiment, the rolling members 130 are balls. The groove wall of the first limiting groove 122 is an arc surface and is matched with the surface of the ball, so that smooth rolling of the ball is facilitated, and smooth and stable movement of the inner rail 120 relative to the outer rail 110 along the first direction XX' is facilitated. Similarly, the groove wall of the second limiting groove 114 is an arc surface and is adapted to the surface of the ball, so that smooth rolling of the ball is facilitated, and smooth and stable movement of the inner rail 120 relative to the outer rail 110 along the first direction XX' is facilitated.
In other embodiments, the rolling elements may be other rolling structures such as cylindrical rollers.
Referring to fig. 1 and 2, in an embodiment, the plurality of rolling elements 130 are arranged in at least two rows of rolling elements 130 arranged at intervals along the second direction YY ', and each row of rolling elements 130 includes a plurality of rolling elements 130 arranged in sequence along the first direction XX'. Thus, the inner rail 120 can move more stably relative to the outer rail 110, and the bearing capacity of the sliding rail is stronger.
In the embodiment shown in fig. 2, the plurality of rolling members 130 are arranged in two rows of rolling members 130 spaced apart in the second direction YY'.
In other embodiments, the plurality of rolling elements may be arranged in three or more rows of rolling elements spaced apart along the second direction. Of course, it is also possible for a plurality of rolling elements to discharge only one row of rolling elements arranged in succession in the first direction XX'.
Referring to fig. 2, in an embodiment, a first protrusion 123 protruding away from the bottom wall 111 is formed at a middle portion of the inner rail 120 along the second direction YY', and the first protrusion 123 protrudes from the outer rail 110 away from the bottom wall 111, so that the first protrusion 123 is convenient for connecting with a chassis of the blade server.
In the embodiment shown in fig. 2, the first protrusion 123 is located between the two rows of rolling members 130 in the second direction YY'.
Referring to fig. 1 and 2, in one embodiment, the sliding rail further includes a middle rail 140 disposed in the groove 113. The middle rail 140 is in moving engagement with the groove 113 in the first direction XX'. The middle rail 140 is provided with mounting holes 141 corresponding to the rolling elements 130, and the rolling elements 130 are mounted in the corresponding mounting holes 141, so that the mounting holes 141 can limit the positions of the rolling elements 130 relative to the middle rail 140, and further facilitate smooth and stable movement of the inner rail 120 relative to the outer rail 110 along the first direction XX'. Wherein the upper and lower ends of the rolling member 130 protrude through the mounting holes 141, respectively, so that the inner surface 121 and the bottom wall 111 can be engaged with the rolling member 130, respectively. It will be appreciated that when the inner rail 120 moves in the first direction XX 'relative to the outer rail 110, the rolling member 130 rolls in the first direction XX' between the inner rail 120 and the outer rail 110.
The rolling elements and the mounting holes can be in one-to-one correspondence, or one mounting hole can be corresponding to a plurality of rolling elements.
Referring to fig. 2, in an embodiment, a second protrusion 142 protruding toward the bottom wall 111 is formed at a middle portion of the middle rail 140 along the second direction YY', and the second protrusion 142 can serve to strengthen the middle rail 140.
Referring to fig. 3 and 2, in an embodiment, an inner stop portion 115 is disposed at one end of the outer rail 110 along a positive direction (i.e. OX 'direction) of the first direction XX', and the inner stop portion 115 is used to stop the inner rail 120, wherein the positive direction of the first direction XX '(i.e. OX' direction) is defined as a direction when the chassis of the blade server is inserted into the cabinet. Since the inner stopper 115 is disposed at one end of the outer rail 110 in the positive direction XX ' (i.e. OX ') of the first direction XX ', when the chassis of the blade server is inserted into the rack, the inner rail 120 is stopped by the inner stopper 115, so that it is convenient to determine whether the chassis is inserted in place, and the insertion position of the chassis is prevented from being too deep.
Referring to fig. 2, in an embodiment, two ends of the middle rail 140 along the second direction YY 'respectively have first matching walls 143 bent in a direction away from the bottom wall 111 (i.e. OZ' direction). The outer rail 110 further includes two first bending walls 116, and the two first bending walls 116 are connected to one end of the two side walls 112 facing away from the bottom wall 111 in a one-to-one correspondence. The first bending wall 116 is bent toward the inside of the groove 113 along the second direction YY 'with respect to the corresponding side wall 112, so that the first engaging wall 143 is stopped from moving in a direction away from the bottom wall 111, thereby preventing the middle rail 140 from being separated from the outer rail 110 in a direction away from the bottom wall 111 (i.e., OZ' direction).
Wherein, the first bending wall 116 and the corresponding side wall 112 may be integrally formed.
Referring to fig. 2, in an embodiment, two ends of the inner rail 120 along the second direction YY 'have second mating walls 124 bent in a direction away from the bottom wall 111 (i.e. OZ' direction). The outer rail 110 further includes two second bending walls 117, where the two second bending walls 117 are connected to one end of the two first bending walls 116 away from the corresponding side walls 112 in a one-to-one correspondence manner, and the second bending walls 117 are bent relative to the corresponding first bending walls 116 in a direction away from the bottom wall 111 (i.e. OZ ' direction) so as to limit the second mating walls 124 correspondingly in the second direction YY ', so that the position of the inner rail 120 is defined between the two second bending walls 117, and further, the inner rail 120 can be ensured to move along the first direction XX ' relative to the outer rail 110.
Wherein, the second bending wall 117 and the corresponding first bending wall 116 may be integrally formed.
Referring to fig. 2, in an embodiment, the outer rail 110 further includes two third bending walls 118, where the two third bending walls 118 are connected to one end of the two second bending walls 117 away from the corresponding first bending walls 116 in a one-to-one correspondence manner, and the third bending walls 118 are bent toward the inner side of the groove 113 along the second direction YY 'relative to the corresponding second bending walls 117, so that the second engaging walls 124 are stopped from moving in a direction away from the bottom wall 111, so that the inner rail 120 can be prevented from being separated from the outer rail 110 in a direction away from the bottom wall 111 (i.e. OZ' direction).
Wherein, the third bending wall 118 and the corresponding second bending wall 117 may be integrally formed.
In this embodiment, the inner rail 120 and the middle rail 140 are respectively movably matched with the outer rail 110 along the first direction XX' by the combined action of the first bending wall 116, the second bending wall 117 and the third bending wall 118. At the same time, the rolling elements 130 can be clamped between the inner surface 121 of the inner rail 120 and the bottom wall 111 to load the chassis.
Referring to fig. 4 to 7, the slide rail further includes an outer stop portion 117, a rotating member 150, a lever 160, and an elastic member 170. The outer stopper 117 is provided to the outer rail 110. The rotating member 150 is rotatably connected with the inner rail 120, and the rotating member 150 has a first angle and a second angle rotated relative to the inner rail 120. The shift lever 160 is located between the inner rail 120 and the outer rail 110. The shift lever 160 is connected to the inner rail 120 through the elastic member 170, and the elastic deformation of the elastic member 170 allows the shift lever 160 to reciprocate along the first direction XX', so that the shift lever 160 can drive the rotating member 150 to switch between the first angle and the second angle.
The opposite direction of the first direction XX' (i.e., OX direction) is defined as the direction in which the chassis of the blade server pulls out of the enclosure. The process of pulling the cabinet out of the cabinet is divided into a first stage and a second stage according to time sequence.
In the first stage, no external force is applied to the elastic member 170, the elastic member 170 is in a natural state, the lever 160 is in a first position relative to the inner rail 120, and the rotating member 150 is at a first angle. The inner rail 120 moves with the case in the opposite direction of the first direction XX ' (i.e., OX direction), so that the lever 160 and the rotary member 150 move with the inner rail 120 in the opposite direction of the first direction XX ' (i.e., OX direction), until the rotary member 150 connected to the inner rail 120 reaches the outer stopper 117, and the outer stopper 117 can stop the rotary member 150 at the first angle from moving in the opposite direction of the first direction XX ' (i.e., OX direction), and can then stop the inner rail 120 from moving in the opposite direction of the first direction XX ' (i.e., OX direction), i.e., stop the case from moving in the opposite direction of the first direction XX ' (i.e., OX direction). In this way, the case can be prevented from being damaged by personnel caused by rapid punching out of the cabinet due to inertia in the process of pulling out the cabinet, namely, the buffering effect on the case is achieved through the outer stop portion 117.
After the first stage, the lever 160 can be moved to the second position along the first direction XX' relative to the inner rail 120 by toggling the lever 160 to overcome the elastic force of the elastic member 170. When the shift lever 160 moves from the first position to the second position, the rotating member 150 is driven to rotate from the first angle to the second angle, so that the outer stop portion 117 releases the rotating member 150. At this time, the rotating member 150 can move in the opposite direction (i.e. OX direction) of the first direction XX ', and the inner rail 120 and the chassis can move in the opposite direction (i.e. OX direction) of the first direction XX ', so that the chassis enters the second stage of movement and continues to be pulled out of the cabinet in the second stage, i.e. the chassis and the inner rail 120 move in the opposite direction (i.e. OX direction) of the first direction XX ', until the chassis moves out of the cabinet.
The elastic member 170 may be a coil spring or other elastic structures such as an elastic strip.
Referring to fig. 5 and 8, in an embodiment, a chute 161 inclined to the first direction XX' is provided on the lever 160, and a sliding portion (not shown) is provided at one end of the rotating member 150. The sliding portion is in sliding engagement with the chute 161. When the lever 160 moves along the first direction XX', the rotating member 150 can be switched between the first angle and the second angle through the sliding fit of the sliding portion and the chute 161.
In other embodiments, the two ends of the connecting rod can be respectively connected with the rotating member and the shift lever in a rotating way, so that when the shift lever moves along the first direction, the connecting rod can drive the rotating member to switch between the first angle and the second angle.
Referring to fig. 5 and 7, in an embodiment, the rotating member 150 is provided with a limiting hook 152, and when the rotating member 150 rotates to a first angle, the limiting hook 152 hooks the outer stop portion 117 in a direction opposite to the first direction XX' (i.e. OX direction), so that the limiting hook 152 is stopped by the outer stop portion 117. When the rotating member 150 rotates to the second angle, the limiting hook 152 moves to one side of the outer stop portion 117 along the second direction YY ', and is dislocated with the outer stop portion 117 along the second direction YY ', so that the limiting hook 152 is not stopped by the outer stop portion 117 in the first direction XX ', that is, the outer stop portion 117 releases the rotating member 150.
Referring to fig. 8, in an embodiment, the inner rail 120 is provided with an avoidance groove 125, and the position of the avoidance groove 125 corresponds to the chute 161. The sliding portion extends into the escape groove 125 through the chute 161. By providing the escape groove 125, the sliding portion can be made longer in size, and the sliding portion can be prevented from being disengaged from the chute 161 as much as possible.
Referring to fig. 5, in an embodiment, a toggle button 162 is disposed on the lever 160 to facilitate movement of the toggle lever 160 in the first direction XX'.
Referring to fig. 5, in an embodiment, a guiding slot 163 is formed on the lever 160, a guiding portion 126 is formed on the inner rail 120, and the guiding portion 126 is slidably engaged with the guiding slot 163 along a first direction XX ', so as to guide the lever 160 to move exactly along the first direction XX'.
